Problems solved by technology
[0002] At present, when drilling the ignition hole of the gear, the paired gear is often used to determine the tooth shape, and the fixture itself cannot be tested. The fixture can only be adjusted according to the actual measurement of the processed product. After the adjustment, the positioning gear is fixed by welding. The fixture after welding is deformed due to internal stress, the use of the fixture is very unstable, it takes a long time to debug the fixture, the product quality is unstable, and the pass rate is low

Embodiment Construction
[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0013] Such as figure 1 A fixture for drilling the ignition hole on the end surface of a gear shown in —3, consists of a drilling template 1, a latch 2, a latch seat 3, a mandrel 4, a foot 5, a nut 7, a supporting nail 8, a split washer 9, a positioning block 10, a ring Washer 11, cylindrical pin 12, screw 13 etc. are formed. The drilling template 1 is square and horizontally arranged, and the drilling template 1 has a round hole for installing a fixed drill sleeve 1a, and the fixed drill sleeve 1a corresponds to the position of the ignition hole 6a of the gear 6. There are four legs 5 located below the drill template 1, which are distributed in a rectangle and correspond to the four corners of the square drill template 1 respectively. The four legs 5 are used to support the drill template 1, and the legs 5 are threaded with the drill template 1. Three supp...

The invention discloses a gear ignition hole drilling clamp which comprises a horizontally-arranged drill plate (1), a mandril (4) sequentially penetrates through a gear (6) and the drill plate (1) from bottom to top, and two ends of the maindril (4) are fastened respectively by nuts (7), the drill plate (1) is provided with a supporting nail (8) used for supporting the gear (6), a bolt seat (3) is fixedly arranged at one side of the drill plate (1), a bolt (2) penetrates through the bolt seat (3) horizontally and extends to the position below the drill plate (1), the spherical head (2a) of the bolt (2) is clamped between two teeth of the gear (6) for positioning the gear (6), and a fixed drill bushing (1a) is arranged on the drill plate (1), corresponding to an ignition hole (6a) of the gear (6). By using the spherical head of the bolt to position the gear, the clear detection data on whether the clamp is qualified or not can be obtained before the ignition hole is drilled, thereforethe regulation time of the clamp is shortened, and the product positioning precision and the clamp stability can be improved.
Description
technical field [0001] The present invention relates to a mechanical drilling jig for drilling gear ignition holes. Background technique [0002] At present, when drilling the ignition hole of the gear, the paired gear is often used to determine the tooth shape, and the fixture itself cannot be tested. The fixture can only be adjusted according to the actual measurement of the processed product. After the adjustment, the positioning gear is fixed by welding. The welded fixture is deformed due to internal stress, the use of the fixture is very unstable, the debugging of the fixture takes a long time, the product quality is unstable, and the pass rate is low. Contents of the invention [0003] The purpose of the present invention is to provide an easy-to-adjust drilling jig, which has stable product quality, high pass rate and can detect whether the jig is adjusted in place before processing the product. [0004] In order to achieve the above purpose, the present invention ...
