[0033] See also Figure 1-4 A pressure test tool for an automobile ABS pump comprises a base 1, a clamping assembly 2, a limiting assembly 3 and a docking assembly 4, wherein the clamping assembly 2 is arranged on the base 1, the limiting assembly 3 and the clamping assembly 2 are arranged on the base 1 on the opposite side, and the docking assembly 4 comprises a tube body 41 arranged on the clamping assembly 2, one end of the tube body 41 can move along the base 1, a pre-positioning member 42 that can move along the tube body 41 is arranged on the tube body 41, and a connector 43 is arranged on one end of the pre-positioning member 42 extending to the outside of the tube body 41.

[0034] Based on the above, this embodiment, through the combination of the base 1, the clamping assembly 2 and the docking assembly 4, moves the pre-positioning member 42 along the channel constructed by the tube body 41 between the base 1 and the clamping assembly 2, pushes the connecting head 43 to be inserted into the oil pipe interface of the ABS pump first, and preliminarily positions the ABS pump. Then, the clamping assembly 2 is operated to move toward the ABS pump, and the tube body 41 is brought close to the connecting head 43. After the clamping assembly 2 clamps the ABS pump on the base 1 and the tube body 41 is connected to the connecting head 43, the pre-positioning member 42 is pulled out, and the lower limit assembly 3 is released to achieve precise docking of the external oil pipe during the rapid clamping process of the ABS pump.

[0035] See also Figure 1-4 The clamping assembly 2 includes a driving member 21 disposed on the base 1 , and a pressing plate 22 is disposed at one end of the driving member 21 extending above the base 1 .

[0036] The above-mentioned clamping assembly 2 presses the ABS pump onto the base 1. The base 1 adopts a concave cross-section design. A threaded hole is preset on one side of the base 1. The driving member 21, which is preferably a threaded rod, rotates and engages to drive the pressure plate 22 to move inside the base 1, pushing the ABS pump to the other side of the base 1, and completing the clamping and fixing after contact.

[0037] See also Figure 1-4 The limiting assembly 3 is symmetrically arranged on the guide rails 31 on the base 1 , a mounting seat 32 is arranged between the guide rails 31 , and a pressing rod 33 is symmetrically arranged on the mounting seat 32 .

[0038] Based on the concave design of the base 1, the ABS pump is pushed in from the front and rear sides of the base 1, and the guide rail 31 is vertically arranged with the highest point at the other end of the base 1, and the corresponding mounting seat 32 moves from top to bottom, driving the lower pressure rod 33 to stop the ABS pump from moving and restrict it.

[0039] Taking into account that the ABS pump is in close contact with the other side of the base 1, a connecting hole is opened on the mounting seat 32 of the present embodiment, and a hanger 34 is arranged on the connecting hole. The hanger 34 is in close contact with the base 1, and the hanger 34 designed by the L-shaped slat is rotatably installed in the connecting hole. Under normal circumstances, the hanger 34 is in close contact with the other side of the base 1, and the mounting seat 32 can be positioned between the guide rails 31. After the ABS pump is placed, the mounting seat 32 is first pushed upward to provide a rotation space for the hanger 34, which is symmetrical with the original position. Finally, the mounting seat 32 is lowered to drive the pressure rod 33 to contact the ABS pump.

[0040] See also Figure 1-4The tube body 41 includes a connecting tube 411 arranged on the pressure plate 22, one end of the connecting tube 411 can move along the base 1, and a plug connector 412 is arranged on the other end of the connecting tube 411. The pre-positioning member 42 includes a positioning rod 421 that can move along the connecting tube 411, and a push rod 422 is arranged on one end of the positioning rod 421. The push rod 422 is located outside the base 1, and the other end of the positioning rod 421 is located above the base 1.

[0041] The prior art installs the pipeline onto one end of the movable clamp, cooperates with the clamping ABS pump, and connects it to the oil port to complete the efficient connection of the ABS pump, and is convenient for later disassembly. In this embodiment, the pipe body 41 moves with the pressure plate 22. Before the pipe body 41 is operated, the positioning rod 421 is driven to move in the connecting pipe 411 by operating the push rod 422, and then passes through the plug connector 412 and moves toward the ABS pump oil port. When the positioning rods 421 are aligned with the oil ports one by one and enter, it can be indirectly confirmed that the connecting pipe 411 is aligned with the ABS pump oil port, which assists in the installation of the connecting pipe 411.

[0042] The positioning rod 421 auxiliary connecting pipe 411 is connected to the ABS pump oil port. The connector 43 of this embodiment includes a buffer head 431 arranged on the positioning rod 421. The buffer head 431 is provided with a buffer sleeve 432. The buffer sleeve 432 is located outside the positioning rod 421, and the buffer sleeve 432 is adapted to the plug connector 412.

[0043] By connecting the connector 43 with the positioning rod 421, the positioning rod 421 can first enter the oil port under the movement of the positioning rod 421 to seal the oil port, and then cooperate with the movement of the connecting pipe 411 to insert the plug connector 412 into the buffer sleeve 432, and finally, the positioning rod 421 is pulled out by the push rod 422 to complete the sealed connection between the tube body 41 and the ABS pump oil port.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
