[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides a drilling fixture for a reverse gear shaft, comprising a fixture base (1) and a fixing device, wherein the fixing device comprises clamping devices distributed on the left and right sides above the fixture base (1) and pressing devices distributed on the front and rear sides above the fixture base (1), and the right side of the clamping device is adjustable; based on the above structure, by adjusting the position of the reverse gear shaft during the processing of the reverse gear shaft, accurate positioning of the drilling is achieved, and the drilling accuracy rate reaches 100%; and by using the fixture prepared by the present invention, the operation is simple, the adjustment is convenient, the work efficiency is improved, and the labor cost is greatly reduced.

[0020] 2. In the present invention, the fixing block b is arranged on the upper part of the guide block a of the slide rail, and the clamping bolt passes through the fixing guide block. By adjusting the clamping bolt, the fixing block b is adjusted. Based on the above structure, the user can adjust and fix the position of the reverse gear shaft according to the actual needs of the processing to facilitate the drilling processing, so that the reverse gear shaft and the tool are more easily and accurately aligned, and the operation is simpler. By adjusting the clamping bolt to adjust the fixing block b, the adjustment and fixation of the position of the reverse gear shaft during the processing are convenient, and the installation and disassembly of the reverse gear shaft is also more convenient, and the disassembly and assembly will not cause damage to the reverse gear shaft.

[0021] The slide rail is fixed on the fixture base, the guide block is set on the slide rail and can slide, and the fixed block b (8) is fixed on the guide block to avoid the fixed block b directly contacting the slide rail, causing the fixed block to be unstable and vibrate during processing.

[0022] 3. In the present invention, the pressure plate is in an inverted concave structure, the long end is pressed on the fixture base, and the short end is pressed on the part to be processed. The clamping spring is fixedly connected to the pressure plate and the fixture base. The screw hole above the pressure plate is elliptical, and the adjustable bolt passes through the screw hole to fix the pressure plate. Based on the above structure, the position of the pressure plate can be adjusted forward and backward, and the pressure plate can also be pressed more stably on the reverse gear shaft.

[0023] 4. The fixing block a and the fixing block b are of V-shaped structure or U-shaped structure. The fixing block a and the fixing block b work together, and the clamping effect of the pressure plate and the clamping spring makes the reverse gear shaft more firmly fixed on the fixture, greatly improving the overall stability of the fixture, making it less likely to move during the drilling process, improving the safety of the drilling process, and realizing accurate positioning of the reverse gear shaft drilling during the processing process.

[0024] 5. In the process of processing, the present invention avoids the occurrence of over-large or under-sized drilling caused by the position deviation of the reverse gear shaft due to continuous vibration during the drilling process through the continuous force of the compression spring.

[0025] 6. In the present invention, a boss is arranged on one side of the quick-change drill sleeve, which is then pressed and fixed with fixing bolts, so that the processing process is safer and more stable, and the drill bit is not easy to move abnormally.

[0026] 7. In the present invention, after the drilling template is fixed, it is only necessary to select fixed blocks a of different specifications according to the gear shaft to be drilled. The position of the gear shaft is determined by the fixed block a. The fixed block a is fixedly connected to the right side of the column. The fixed block b is clamped and positioned on the basis of the fixed block a to realize the drilling processing of the reverse gear shaft.

[0027] 8. In the present invention, a slide rail guide block b is installed at the bottom of the fixed block a, so that different parts can be processed without changing the drilling template and the fixed block, and converted into a universal fixture to achieve more operability.
