Abstract
The invention relates to a production process of a press-welding brake, which comprises the technical scheme of fabricating a bottom plate and an air chamber bracket. The production process is characterized in that the process of the brake bottom plate comprises the steps of: turning a center hole and an end face, drilling a flange hole, facing, milling the end face of a camshaft hole and the end face of a shoe piece shaft hole, boring, drilling a bracket hole and a dustproof cover hole, and drilling four connecting bracket threaded holes; the process of the air chamber bracket comprises the following steps of: boring, turning the end face, drilling a bottom surface hole, milling an air chamber surface, and drilling an air chamber surface hole and a lubricating nipple hole. By applying the process of the invention, the press-welding brake can be processed by using lathes, milling machines and drilling machines frequently used in the industry. The process has flexible and reliable arrangement without purchasing many special lathes.
Description
Technical field
The present invention relates to a kind of production technology of vehicle press-welding brake, relate in particular to the back-plate of press-welding brake, the production technology of air chamber support, belong to automobile and accessory thereof and make the field.
Background technology
At present, brake generally is as main drum brake take founding materials.Along with the development of vehicle bridge industry, according to the demand of each producer, press-welding brake more and more receives an acclaim.Press-welding brake has the quality of alleviating, superior, the stock utilization advantages of higher of structure.But it is higher that press-welding brake exists cost of manufacture, the problem of complex manufacturing technology.
Summary of the invention
For the deficiency that prior art exists, this practicality invention technical problem to be solved provides a kind of production technology of press-welding brake, to reduce cost of manufacture, simplifies manufacture craft.
For solving the problems of the technologies described above, the production technology of press-welding brake of the present invention, its technical scheme of taking is that it comprises following content:
It comprises the process program of back-plate, air chamber support, wherein:
The technological process of back-plate is: car centre bore and end face, brill flange hole, ream are put down, are milled the camshaft hole end face and mill shoe shaft hole end surface, bore hole, brill and attack bracket holes, bore attacking and defending dust hood hole, bore and attack four connection bracket screwed holes;
The technological process of air chamber support is: bore hole, face work, brill bottom hole, mill the air chamber face, bore the air chamber face, bore and attack the oil nozzle hole.
The production technology of above-mentioned press-welding brake, the technological process of its air chamber support is:
1, support external cylindrical surface with V-block, upper V-type briquetting workpiece pressing, knife bar band cutter carries out bore hole;
2, with camshaft hole location and end face location, come clamping work pieces to carry out face work by tightening the conical surface screw spreading core that rises;
3, with camshaft hole and end face location, screw holds out against the air chamber end face, and bushing plate is inserted in two locating dowels and compresses the other end, bores bottom hole;
4, with camshaft hole and end face location, flat with adjusting the screw adjustment, hold out against with dog screw, plate compresses the camshaft hole other end, then mills the air chamber face;
5, with camshaft hole and end face location, hold out against the air chamber end face with the pallet centering, plate compresses the camshaft hole other end and bores the air chamber face;
6, brill is attacked the oil nozzle hole.
435 car centre bore and end face, 457 brill flange hole are because workpiece and frock interference, bad processing in the technology establishment of back-plate.We arrange and have made frock, process with engine lathe and radial drill.Milling the camshaft hole end face and milling in the shoe shaft hole end surface operation, we adjust rig, adjust the spacing of facing cutter by being inserted in cutterhead mandrel positioning sleeve.Brill attacking and defending dust hood hole and brill are attacked four screwed holes and have also all again been made frock.In the technological process of air chamber support, particularly first step bore hole does not have suitable cutter owing to the hole is long, and we are provided with knife bar, have so namely reduced cost and have been easy to use again.
Use technique of the present invention, as long as just can process press-welding brake with usual lathe, milling machine, the drilling machine that uses of the industry.
