Abstract
The utility model discloses a special fixture for drilling the end part of a locomotive traction pin. The special fixture comprises a fixture body (1), wherein the bottom end of the fixture body (1) is provided with a blind hole (1.1) which can be sleeved on the end part of a locomotive traction pin (5), and the upper end surface of the fixture body (1) is provided with a mounting hole (1.2) for installing a drill bushing (2). The mounting hole (1.2) is communicated with the blind hole (1.1), and the drill bushing (2) is inserted into the mounting hole (1.2) of the fixture body (1). Through the special fixture, the traditional radial drilling machine can machine a locomotive traction pin workpiece. Thus, the original machining center machining for the workpiece is converted into radial drilling machine machining, and the machining quality completely meets the technical requirements of drawings. According to the special fixture disclosed by the utility model, a great deal of cost is saved, and the machining efficiency is increased. The special fixture is simple to operate, has no high technical level requirement on workers and is suitable for volume production.
Description
Technical field
The utility model relates to a kind of locomotive traction pin end boring special fixture, belongs to locomotive traction pin processing aid technical field.
Background technology
The locomotive traction pin is part, particularly P5 towing pin commonly used on traditional combustion engine car or an electric locomotive vital part on the locomotive especially, and this part plays an important role to traffic safety.Usually on the small end face of locomotive traction pin, require processing 4-M24 screwed hole; The position degree is 0.1mm; Adopt relatively difficulty of machine tool processing; Adopt the processing of holing of expensive machining center equipment in the prior art often, therefore not only exist the high problem of processing cost, but also exist production efficiency low, be unfavorable for the problem produced in enormous quantities.
Summary of the invention
The purpose of the utility model is: provide that a kind of production efficiency is higher, cost is lower, and can guarantee the locomotive traction pin end boring special fixture of crudy, to overcome the deficiency of prior art.
The technical scheme of the utility model is to constitute like this: a kind of locomotive traction pin of the utility model end boring special fixture; Comprise clamp body; Be provided with the blind hole that can be enclosed within on the locomotive traction pin end in the bottom of clamp body; Be provided with the installing hole that drill bushing is installed in the upper surface of clamp body, and installing hole communicates with blind hole, drill bushing inserts in the installing hole of clamp body.
On the upper surface of above-mentioned clamp body, be provided with 4 installing holes that drill bushing is installed, in each installing hole, all be separately installed with a drill bushing.
Above-mentioned drill bushing is the convex structure that is provided with the back-up ring formula, and a screw that presses solidly that can be pressed on the drill bushing back-up ring position all is housed on the next door of each installing hole on the clamp body end face.
Above-mentioned clamp body is a cylindrical shape, and around clamp body cylindrical, is arranged with 4 set screw that are used for the concrete center of adjustable clamp.
Owing to adopted technique scheme; The utility model can accurately entangle the position, upper end of processed locomotive traction pin in use; And can be according to the situation of locomotive traction pin; Come adjustable clamp specifically to cooperate through set screw,, just can solve the bigger problem of position degree deviation in hole in when work symmetry four set screw of screwing gently with the accurate of locomotive traction pin.Can be implemented in existing radial drilling machine through the utility model processes locomotive traction pin workpiece.Make this workpiece change radial drilling machine processing into, and crudy meet the drawing specification requirement fully by original Cutter Body Processing with Machining Center.Therefore, the utility model has not only been practiced thrift a large amount of costs, has been improved working (machining) efficiency, but also have simple to operate, less demanding to workman's technical merit, be suitable for advantages such as production in enormous quantities.
