Embodiment
In order to make goal of the invention of the present utility model, technical scheme and Advantageous Effects thereof more clear, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.Should be understood that, the embodiment described in this instructions is only used to explain the utility model, is not intended to limit the utility model.
Refer to Fig. 1 and Fig. 2, the utility model focusing of microscope device is arranged on microscope stand, and it comprises installation frame 101 and focusing framework 102.
Installation frame 101 is shaft-like, and its one end is microscope installation end 103, and the other end is focusing end 104.Microscope installation end 103 is preferably annular, is locked in the center pit 123 that microscope is arranged on annular by screw 124.Focusing end 104 presets embedding focusing nut 106 wherein.
The middle part of focusing framework 102 offers the groove 105 of a longitudinal direction, and the focusing end 104 of installation frame 101 is preset in the groove 105 of focusing framework 102.The framework of groove 105 top and bottom offers respectively the screw be in alignment with each other, a focusing screw 107 runs through focusing framework 102 by focusing nut 106 from top to down of screw and focusing end 104, thus can be arranged on by focusing end 104 in focusing framework 102 up or down; The top of focusing screw 107 is installed with the longitudinal handwheel 108 of handled easily.Because the shape of cross section of the focusing edge shape of end 104 and groove 105 is suitable, therebetween connection is connected but not interference connection for adaptive, therefore focusing screw 107 can be utilized to drive installation frame 101 upper and lower displacement by rotating longitudinal handwheel 108, making the microscope of the installation end 103 being arranged on installation frame 101 move up and down and realize focusing action.
In order to avoid or reduce focusing time due to microscope Action of Gravity Field occur tenesmus, the utility model also presets two Compress Springs 113,114 be set on focusing screw 107 in the groove 105 of focusing framework 102, two Compress Springs 113,114 lay respectively at the both sides up and down of focusing end 104 and are preset with certain decrement separately, therefore can ensure that focusing screw 107 rotates under certain tension force.Radially wobbling of installation frame 101 can not only be reduced like this, and when longitudinal handwheel 108 can be made to rotate, there is more continuous print feel.
Refer to Fig. 2, in order to reduce radially wobbling of installation frame 101 further, the focusing end 104 of installation frame 101 and the groove 105 of focusing framework 102 are designed to suitable concavo-convex snap-in structure by the utility model, such as focusing end 104 is designed to the bulge-structure 201 with three semicolumns, the groove 105 of focusing framework 102 is correspondingly designed to the groove structure 202 with three semicolumns simultaneously.
In addition, the utility model offers pin-and-hole respectively again on focusing groove 105 top of framework 102 and the framework of bottom, offers pin-and-hole accordingly at the focusing end 104 of installation frame 101 simultaneously; Be separately fixed in the corresponding pin-and-hole of installation frame 101 by the two ends 115,116 of register pin 203, the middle part of register pin 203 can be inserted in the pin-and-hole of focusing end 104 up and downly, thus avoids radially wobbling of focusing end 104 further.
Refer to Fig. 1, the microscope stand for installing above-mentioned focus control comprises bracket base 112 and column 111.Wherein, bracket base 112 is for being horizontally disposed with, and column 111 is vertically fastened on bracket base 112.The focusing framework 102 of focusing of microscope device is just being installed with column ring 109 to the rear side of groove 105, column ring 109 presets the screw 110 of band handwheel.During installation, column ring 109 is set on column 111, screw 110 can be utilized can be arranged on microscope stand to up-down adjustment by focusing of microscope device.Obviously, the coarse adjustment (i.e. the adjustment of microscope high and low position) of microscope focus can be realized by the position adjustments of column ring 109 on column 111.
In order to reduce production cost also for ease of maintenaince, the focusing nut 106 that the utility model focusing of microscope device uses, focusing screw 107 and screw 110,124 etc. all adopts standard component, and nut 106 of such as focusing generally can select the standard component embedding nut of commercially available M8 or M10.Like this, when wearing and tearing appear in each screw and nut in use for some time, the standard component more renewed only is needed.
Because the radially wobbling when doing focusing displacement of minimizing focusing of microscope device is the key of improving the quality of products, therefore the utility model focusing of microscope device generally adopts aluminium to produce in batches with mould drawing focusing framework 102 and installation frame 101.This is because have very high precision with the structure of aluminium section bar to circular hole and semicolumn of mould drawing, it can ensure register pin 203, semicolumn protruding 201 and the isostructural precision of groove 202, thus radially wobbling when more effectively reducing focusing displacement.
Known by describing above, the focusing of microscope apparatus structure that the utility model proposes is simple, processing and install all very convenient, and compared with prior art, it at least has the following advantages:
1) estimation of processing cost, installation cost and material cost sum is only below 100 yuans, is significantly less than the focusing of microscope device (cost is at least more than 200 yuans) of existing gear & rack structure;
2) by longitudinal handwheel, microscope is focused, therefore without the need to lateral operation space, avoid the not enough problem of the very compact horizontal space caused in operating space on existing micro-welding automatic production line.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of the utility model claim modifications and changes more of the present utility model.In addition, although employ some specific terms in this instructions, these terms just for convenience of description, do not form any restriction to the utility model.
