The invention relates to a brake disc processing technology, step 1: rough and fine car brake disc small end two friction surfaces; step 2: rough and fine car brake disc big end two friction surfaces; step 3: processing the brake disc big end Holes on the end face and small end face; Step 4: Dynamic balance and weight removal inspection; when turning the large end face and small end face of the brake disc, double-end turning tools are used to improve processing efficiency and ensure the stability of the braking effect. When processing the holes of the big end face and small end face of the brake disc, the fourth-axis rotary table is used to realize the end face hole processing, and the process merging is considered in the process design to reduce the process turnover bump. The dynamic balance de-weight detection adopts the tensioning fixture to improve the dynamic balance accuracy of the brake disc product, and realizes the same self-centering clamping function through the expansion force of the expansion sleeve to expand and open the expansion flap, which can not only meet the balance process requirements of the brake disc It can also reduce the manufacturing cost of the process fixture.

The invention discloses a tight braking device of a rotating workbench. The device is characterized by comprising upper press plates and lower press plates, wherein the upper press plates and the lower press plates are oppositely arranged, and tight braking rings are arranged in gaps between the upper press plates and the lower pressing plates. Each upper press plate comprises an upper press plate elastic device and an upper press plate pushing device, the upper press plate elastic device is arranged on the bottom face of the upper press plate, and the upper press plate pushing device can push the upper press plate elastic device to deform. Each lower press plate comprises a lower press plate elastic device and a lower press plate pushing device, the lower press plate elastic device is arranged on the top face of the lower press plate, and the lower press plate pushing device can push the lower press plate elastic device to deform. The upper elastic devices and the lower elastic devices are simultaneously pushed by the upper pushing devices and the lower pushing devices, pressing devices of the tight braking device are arranged between the upper elastic devices and the lower elastic devices, the tight braking rings fixedly connected with a rotary table of the workbench have no influences on rotating accuracy of the workbench, and the rigid requirement for the workbench is also lowered. The tight braking device of the rotating workbench is convenient to detach and adjust, long in service life and low in cost.

The invention provides a two-way check valve easy to adjust. The two-way check valve comprises a valve body, wherein an exhaust passage is arranged in the valve body; a metering pin valve is arranged on the upper side of the valve body and comprises a flow adjusting lever and a locknut; the flow adjusting lever is partially arranged in the exhaust passage and partially extends out of the valve body; the locknut is arranged on the outer side of the valve body and is used in coordination with the flow adjusting lever; the lower side of the valve body is connected with a connector through an intermediate housing or is directly connected with the connector; and an air inlet or an air outlet, which is communicated with the exhaust passage, is formed in the connector, and correspondingly, an air inlet or an air outlet, which is communicated with the exhaust passage, is formed in the side wall of the valve body. Compared with the prior art, the two-way check valve has the advantages that the air inflow can be adjusted; the braking forces of a number of wheels are balanced; after braking, air in a brake chamber can be exhausted quickly; and the two-way check valve is energy-saving and environment-friendly.
