Detailed Description
In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Example 1:
Referring to fig. 1 to 4, the present embodiment provides a high torque linear module, which includes a screw nut assembly and a high torque driving assembly that are used in combination, and a mounting base for mounting the screw nut assembly and the high torque driving assembly.
In the following, specifically, the screw-nut assembly used in the present embodiment includes a screw 11 and a nut 12 which are used in cooperation, and a high torque driving assembly is directly or indirectly connected to the screw 11 to be adapted to drive the screw 11 to operate. By way of example, in connection with the figures, the high torque drive assembly employed in this embodiment comprises a gear motor, a coupling 24 for connecting the gear motor and the screw 11, and an encoder 23 connected to the gear motor. Wherein, in the gear motor, the rotating motor 22 is directly connected through the reduction gearbox 21, the output torque of the motor is amplified, the encoder 23 is used for the feedback of the motor and can realize torque control through driving and control, so as to realize a small-sized module with high torque.
Any mature means in the prior art can be directly adopted for the specific screw-nut component and the high-torque driving component, and the embodiment is not improved, so that the specific implementation principle of the embodiment is not repeated here.
The mounting seat comprises a support base 31 and a mounting frame 32 which are integrally formed and vertically connected, wherein the mounting frame 32 and the support base 31 form an L-shaped structure, and the L-shaped structure can be changed into an inverted T-shaped structure, so that the embodiment is not limited. The mounting frame 32 is used for fixing a high-torque driving assembly, and the supporting base 31 is provided with a sliding rail assembly matched with the nut 12.
Specifically, the sliding rail assembly used in this embodiment includes a linear sliding rail 42 fixed on the supporting base 31 and a sliding block 41 slidably matched with the linear sliding rail 42, and the nut 12 is fixedly connected with the sliding block 41. The nut 12 and the slide 41 can also be connected here by means of a connecting socket 43. This embodiment is not limited in any way.
Based on the above, the mounting base further includes a pair of support frames 5 vertically disposed on the support base 31, for which, the screw 11 is mounted on a support frame 5 adjacent to the high torque driving assembly in the pair of support frames 5 through a first bearing 61, and the screw 11 is also mounted on a support frame 5 far from the high torque driving assembly in the pair of support frames 5 through a second bearing 62. It should be noted that, for improving the stability of the high torque type linear module in the use process of the present embodiment, at least one of the pair of support frames 5 may be integrally formed with the support base 31, and only one of the pair of support frames 5 is integrally formed with the support base 31, while the other support frame 5 is of a detachable assembly structure with the support base 31, and specifically, the integral processing of the support frame 5 with the support base 31 is not limited in this embodiment. In addition, the case where both the support frames 5 are integrally formed with the support base 31 is included. The integrally machined structure not only improves the efficiency of machining, but also reduces the machining difficulty and improves the coaxiality between the screw rod 11, the first bearing 61, the second bearing 62 and the output shaft of the high-torque driving assembly. Of course, the pair of support frames 5 may be detachably assembled and fixed on the support base 31, which is not limited in any way.
It should be noted that in an alternative embodiment, a pre-tightening nut 7 is further provided in the support frame 5 adjacent to the high torque drive assembly of the pair of support frames 5, and the pre-tightening nut 7 is adapted to abut the first bearing 61 towards the shaft side end of the high torque drive assembly.
Based on the above-described structure, in more detail, a through hole adapted to the penetration of the screw 11 is formed in the pretensioning nut 7, in such a structure that the design of the pretensioning nut 7 does not constitute an obstacle to the assembly of the screw 11 with the high torque driving assembly. In addition, a mounting hole for screw-fitting with the pretensioning nut 7 is provided in the support bracket 5 adjacent to the high torque drive assembly in the pair of support brackets 5.
In summary, in this embodiment, the first bearing 61 is matched with the pretensioning nut 7, so that the screw rod 11 is located in the pair of support frames 5, and no axial gap can be generated, thereby enabling the overall high-torque linear module to operate more reliably.
Example 2:
Referring to fig. 1 to 4, on the basis of the high torque type linear module of embodiment 1, since the high torque type linear module of this embodiment has high torque, in order to prevent the sliding blocks 41 from striking the pair of support frames 5 during use, the high torque type linear module of this embodiment further designs an anti-collision assembly.
For example, in an alternative embodiment, the anti-collision assembly includes a pair of photoelectric switches 81 disposed on the pair of support frames 5 in a one-to-one manner, and a pair of light shielding elements 82 disposed on the slider 41 in a one-to-one manner and adapted to the pair of photoelectric switches 81.
For example, in an alternative implementation case with reference to the drawings, the photoelectric switch 81 on the support frame 5 may be disposed on one side end face of the support frame 5 along the linear motion direction of the sliding block 41, where the photoelectric switch 81 adopts an L-shaped structure, so that installation is convenient, and the axial space of the whole linear module is not wasted, and for the photoelectric switch 81 with this structure, the sensing probe at least partially protrudes from the side end face of the support frame 5 facing the sliding block 41. In this regard, regarding the light shielding member 82, it may be mounted on one side end surface in the linear movement direction of the slider 41, and the light shielding member 82 and the photoelectric switch 81 used in cooperation therewith are located on the same side of the screw 11. The light shielding member 82 may be an L-shaped structure, and for the photoelectric switch 81 of this structure, a portion for shielding light of the sensing probe of the photoelectric switch 81 is at least partially protruded from a side end surface of the slider 41 facing the support frame 5.
With this structure, the slider 41 moves between the two photoelectric switches 81, and when the slider 41 moves to approach any one of the supporting frames 5, the light shielding element 82 located on that supporting frame 5 shields the light of the photoelectric switch 81, at this time, the high torque type linear module of this embodiment needs to stop or reverse.
In addition, in the high-torque linear module of the present embodiment, the crash cushion 9 may be provided on the side end surfaces of the slider 41 facing the pair of support frames 5 and/or the side end surfaces of the pair of support frames 5 facing the slider 41, and in this case, in the event of failure of the photoelectric switch 81, the impact cushion 9 may serve to cushion the impact generated between the slider 41 and the support frames 5.
It should be noted that, when the screw 11 is connected to the slider 41 through the connecting seat 43, both the light shielding element 82 and the crash cushion 9 of the present embodiment may be disposed on the connecting seat, and, even if the connecting seat 43 is present, the light shielding element 82 and the crash cushion 9 may still be disposed on the slider 41.
