Problems solved by technology

[0002] At present, when performing performance tests on the automatic transmission valve body, the automatic transmission valve body needs to be combined on the test steel plate of the automatic transmission valve body assembly testing machine. Dozens of bolts are needed to fasten the automobile automatic transmission valve body with the test steel plate, and disassembly and assembly are very troublesome, time-consuming and laborious, and the assembly testing machine for the automobile automatic transmission valve body is used as a test vehicle automatic transmission valve The special equipment for the body assembly needs to frequently disassemble the valve body assembly of the automatic transmission of the automobile, causing the internal threaded hole thread on the steel plate of the test machine of the automatic transmission valve body assembly to be broken, and it is necessary to re-expand and tap the thread for repair. It is very difficult, and if it is serious, the whole test steel plate needs to be replaced, resulting in high maintenance costs, poor sealing, oil leakage and pressure relief, etc., time-consuming and laborious operations for workers, too long preparation time for operation, too much invalid work, which affects the valve body assembly Test efficiency seriously affects the normal use of the machine

Abstract

The invention relates to the technical field of testing of automobile transmissions, and in particular relates to a positioning clamping system of a testing machine for an automatic transmission valve body assembly of an automobile. The positioning clamping system comprises a clamping mechanism for positioning and gripping a transmission valve body, and a pressing mechanism for driving the clamping mechanism to tightly press the transmission valve body. According to the system, the transmission valve body is positioned and gripped on the clamping mechanism and then is clamped by the clamping mechanism through the pressing mechanism, so that the transmission valve body is hard to shake. The system is simple in structure, convenient to operate, and accurate and quick to position and grip the transmission valve body; moreover, the transmission valve body is clamped and hard to shake. Therefore, efficiency is greatly improved; the workload of workers is decreased; and a series of disadvantages such as repeated damage and time and force waste can be completely avoided.
