In this embodiment, as shown in fig. 15, the chain conveying unit 10 includes a base platform 1001, a conveying cylinder 1002 is mounted at an upper end of the base platform 1001, a moving platform 1003 is mounted at an output end of the conveying cylinder 1002, the moving platform 1003 is slidably mounted at an upper end of the base platform 1001, a chain engaging clamping strip 1004 is vertically and slidably inserted in a middle part of the moving platform 1003, an engaging movable cylinder 1005 is mounted on the moving platform 1003, a telescopic end of the engaging movable cylinder 1005 is fixedly connected with the chain engaging clamping strip 1004 through a connecting frame, when a chain a needs to be conveyed, the engaging movable cylinder 1005 is started, the chain engaging clamping strip 1004 is pushed to approach and be inserted into a chain groove of a pin chain a conveyed in the chain conveying track 7, and the pin chain a is pulled to be conveyed in cooperation with the starting recovery of the conveying cylinder 1002.
In this embodiment, as shown in fig. 5 and 6, the upper in-place sensor 204 and the lower in-place sensor 205 are respectively installed on the inner wall of the rack II corresponding to the heights of the two ends of the punching stroke of the upper rivet block 202, so that the assembly system is convenient to precisely control the punching rivet stroke of the oil cylinder 201 and ensure the assembly of the pin chain a through the induction of the upper in-place sensor 204 and the lower in-place sensor 205.
In this embodiment, as shown in fig. 9 and 10, a section of the chain conveying track 7 located at the upper end of the table III300 is provided with a counting sensor II405 for counting the chain links 9, and according to the number of links required by the whole assembly system, the pin chain a is fixed back and forth, and the pretensioning mechanism is started to make the total length of the pin chain a reach the specified requirement at the specified number of links.
Example 2
The difference between this embodiment and embodiment 1 is that, as shown in fig. 8, the two sides of the stepping screw 304 are symmetrically distributed with positioning sliding rods extending in the same direction, and the two positioning sliding rods are fixedly mounted on the screw rotating frame, and the two positioning sliding rods are slidably inserted on two sides of the sliding seat, so that the forward and backward sliding of the movable rotating wheel 303 is effectively ensured, and the operation of the forward working procedure and the backward working procedure in the material buffering mechanism 3 is ensured.
Other undescribed structures refer to embodiment 1.
According to the pin-chain automatic assembly machine disclosed by the embodiment of the invention, after the pin 88 and the belt conveyor 103 are automatically sent to the designated positions through the feeding vibration disc 101, the assembly system starts an action instruction after receiving a material-to-material signal, so that the pin 8 and the chain link 9 are automatically assembled, the pin 8 is pre-pressed, and the like, the assembly is continuously carried out on the basis of the materials without shortage, and the semi-finished products of the chain after the pre-pressing are automatically counted from the first according to the required section number requirement and then sent to the rivet station;
after the material induction is obtained at the rivet station, the rivet process is started immediately, the production action of the rivet process is automatically and continuously carried out, meanwhile, according to the requirement of the number of chain sections designed by an assembly system, after the number of the chain sections is finished, the rivet work of the next section is stopped, and the chain is continuously and automatically sent to a material buffer zone before pretensioning and the pretensioning station;
The pre-tensioning is a process action which is carried out on the requirement of the length of the product after the rivet is assembled when the number of the joints is regulated, after the assembly system receives the material induction, the station fixes the chain back and forth according to the number of the joints designed in advance by the assembly system, and starts the pre-tensioning mechanism to enable the total length of the chain to reach the specified requirement when the number of the joints is regulated;
After the pretensioning process is finished, the equipment continues to automatically send the chains to a pin removing station, the station automatically counts the node number requirement of each chain according to the counting requirement of the design of an assembly system after material induction is obtained, the pin 8 without rivet is removed under the pressure action of a cylinder which is multiple times, and the pin 8 is automatically transferred to the next process station, namely a disc circle station;
The coiling station carries out coiling action on the rotary disc 602 on the chain for conveying and discharging from the previous station, after the coiling action is finished, the discharging and pushing mechanism is automatically started, the chain for finishing coiling is pushed out, automatic assembly of the pin chain a is finished, and then the assembled chain products are conveyed and collected by staff.
The embodiments of the present invention are disclosed as preferred embodiments, but not limited thereto, and those skilled in the art will readily appreciate from the foregoing description that various extensions and modifications can be made without departing from the spirit of the present invention.
