Abstract
The utility model provides a fixture for drilling a track plate of a heading machine. The fixture comprises a base, a rotating rack, and a pressure plate, wherein the base and the rotating rack are movably connected with each other through a rotating shaft; the pressure plate is connected with the rotating rack through bolts; a groove matched with the track plate is formed in the middle of the rotating rack; a drilling sleeve is arranged at each of two ends of the rotating rack. The fixture provided by the utility model is simple in structure, light in weight, simple in operation and convenient to mount, can meet the drawing requirements on coaxiality and size tolerance, can guarantee the quality of a product, facilitates the fixation of a workpiece, and can improve the production efficiency.
Description
Technical field
The utility model relates to a kind of fixture, is specifically related to the boring fixture of a kind of development machine creeper tread.
Background technology
Because the shape of creeper tread in development machine is not too regular, the installation way that general boring adopts easily causes hole drill partially or disalignment, be difficult to guarantee size, precision and the drawing requirement in hole, when creeper tread bearing pin is installed, wear to enter, impact is produced and product quality.Because hole number is more, working (machining) efficiency is also lower in addition.
Utility model content
The technical problems to be solved in the utility model is that in development machine, the creeper tread installation way adopting of generally holing easily causes hole drill partially or disalignment, be difficult to guarantee size, precision and the drawing requirement in hole, a kind of the fixing of workpiece that facilitate is provided, improves the machining accuracy of workpiece and the development machine creeper tread fixing device for drilling of production efficiency.
For achieving the above object, the utility model adopts following technical proposals: a kind of development machine creeper tread fixing device for drilling, comprise base, swivel mount and pressing plate, base and swivel mount are flexibly connected by rotating shaft, pressing plate is connected with swivel mount by bolt, in the middle of swivel mount, be provided with the groove matching with described creeper tread, swivel mount two ends are provided with drill bushing.
In the middle of described base and swivel mount, be also provided with alignment pin I, swivel mount is also provided with for fixedly jackscrew, alignment pin II and the connecting bolt of creeper tread.
Described bolt is provided with nut.
Described rotating shaft end is provided with end cap.
Described base comprises gripper shoe and supporting leg.
Adopt the utility model after said structure simple in structure, lightweight, simple to operate, be convenient to install; Axiality and dimensional tolerance all reach drawing requirement, guarantee product quality, facilitate the fixing of workpiece, can also enhance productivity.

The specific embodiment
As shown in Figures 1 to 4, the utility model comprises base 6, swivel mount 5 and pressing plate 4, base 6 and swivel mount 5 are flexibly connected by rotating shaft 11, pressing plate 4 is connected with swivel mount 5 by bolt 3, in the middle of swivel mount 5, be provided with the groove 21 matching with described creeper tread 20, swivel mount 5 two ends are provided with drill bushing 10.
In the middle of described base 6 and swivel mount 5, be also provided with alignment pin I7, swivel mount 5 is also provided with for fixedly jackscrew 13, alignment pin II12 and the connecting bolt 8 of creeper tread 20.
Described bolt 3 is provided with nut 2.
Described rotating shaft 11 ends are provided with end cap 14.
Described base 6 comprises gripper shoe 61 and supporting leg 62.
As shown in Figure 5 and Figure 6, the utility model in use, is installed to the utility model on Drilling machines bench, with alignment pin I7, first swivel mount 5 is positioned on base 6, then creeper tread 20 is put into the groove 21 of swivel mount 5.Fastening jackscrew 13, the nut 2 tighting a bolt on 3, make pressing plate 4 and swivel mount 5 that creeper tread centering is clamped.Then can hole in the drill bushing 10 center of drill bit being aimed on swivel mount 5.Bored after the hole I22 of creeper tread one end, remove alignment pin I7, unclamp nut 2, make swivel mount 5 centered by rotating shaft 11, drive creeper tread 20 Rotate 180s °, because the diameter in the hole of boring on creeper tread is all the same, in order to upper method, by Workpiece clamping, can continue to bore another stomidium II23 on creeper tread.Lower track plate is unloaded after all boring in the hole at creeper tread two ends, another piece creeper tread is installed and is continued boring.
