Car (drilling) * cut - heat treatment * car (processing one end, car medium) silver (drilling 05mm hole, 2-llmm groove bottom hole) one milling (slot) * car (processing another end face) * pliers (go glitch).
Due to the large output of the product, more than 100,000 pieces per year, a set of drilling fixtures () is required on the 2-11mm bottom hole of the fitter drill. When using, loosen the nut 4, remove the open washer 6, and drill the template 2. , remove the workpiece 8, and then install another workpiece on the drill template, insert the indexing pin (not shown), mount the drill template 2 on the clamp, install the opening washer 6, tighten the nut 4, and drill Hole processing.
Clip specific drill template drill sleeve * female * rod open washer positioning plate workpiece because there is no gap between the drill template 3 and the workpiece 9, forming a closed system, difficult to remove chips during drilling, slow drilling speed, drill bit and drill sleeve 3 The wear is severe, and the drill sleeve 3 is basically changed once a month, and the waste is serious. In addition, the clamping is cumbersome, the time is long, and the production efficiency is not high. In the product flow operation, the daily output of other processes is about 600 pieces, and the daily output of this process is only 200 pieces, which seriously restricts the production. After careful study, it was decided to improve the fixture, and the improved drill template template drilling clamp (). In order to solve the problem that the screw 6 hinders the workpiece clamping, the clamp adopts a floating clamping mechanism. When the workpiece is clamped, the screw 6 is at the position of the broken line. After the workpiece is mounted, the screw 6 slides in the center hole of the positioning sleeve 8 to the figure. Position, loading 1. Clip specific 2. Fixed plate 3. Drill template 4. Drill sleeve 5. Township 6.* Rod 7. Opening washer 8. Positioning sleeve 9. Workpiece 10. Horn 11. Anti-rotation drill This set The advantage of the relative cover type drilling jig is that a gap of 5 mm between the drill template and the workpiece forms an open environment, which facilitates chip removal, reduces wear of the drill bit and the drill sleeve, and saves cost. 2 The clamping is simple. When clamping the workpiece, simply loosen the nut 5 and remove the opening washer 7. The clamping time of each clamping workpiece is less than that of the cover drilling fixture. 3 can process two products at a time, reducing the total number of clamping times. 4 The cover type drilling jig needs to repeatedly draw the drill template when clamping the workpiece, and the weight of the drill template is about 1.5kg, the labor intensity of the worker is large, and the clamp only needs to remove the opening washer 7 to reduce The labor intensity of the workers. Thanks to the use of this set of fixtures, the labor productivity is significantly improved, and 600 products can be processed every day to meet the production requirements and solve the bottleneck problem that restricts production.
This technology was listed in the national “Golden Bridge Project†in 1998 and has been promoted nationwide. It has more than 400 enterprises in 30 provinces, autonomous regions and municipalities, and has won users. trust. In the new century, we will continue to provide a full set of materials and limb adhesives (160 yuan wish 0, a bottle of repairable general bearings 5060 sets.
0-shaped 啪 speed kiss 啪 technology 0-ring is small, often due to incomplete specifications, affecting the maintenance schedule, especially imported equipment. We have developed a simple, on-site construction of rapid self-made technology that can easily solve problems.
The technology includes correspondence materials, strips, special adhesives and tools (180 yuan).
According to the above two technologies, the above two technologies can be operated and can be used for long-term limb supply.
