The invention discloses a wedge type brake drum dismounting and clamping device, which includes a bracket, a jacking mechanism, etc., the jacking mechanism includes a positioning sleeve, a jacking sleeve sliding on the positioning sleeve, and a hydraulic cylinder is arranged in the positioning sleeve; The stop-lift conversion mechanism includes a touch lever and a stop-lift arm. A wedge-shaped block is fixed at the lower part of the touch lever. The rotation of the stop-lift arm is set on the inner wall of the jacking sleeve. Lifting teeth, the upper end of the lifting arm cooperates with a wedge block, and the touch bar slides vertically through a spring and is arranged on the support beam at the top of the jacking sleeve. The clamping mechanism includes a hinge shaft fixed horizontally on the support beam, two clamping arms installed on the hinge shaft through the hinge shaft cylinder, and a clamping driving arm is fixed under the two clamping arms, driven by a hydraulic cylinder. The clamping drive arm is connected, and the lift-stop arm is provided with a pressure bar that acts as a limit to the clamping drive arm, and the clamping arm cooperates with clamping the brake drum. The hydraulic cylinder is a pedal hydraulic cylinder.
Description
technical field [0001] The invention relates to the technical field of vehicle maintenance and disassembly, in particular to a wedge-type brake drum disassembly and clamping device. Background technique [0002] The brake system maintenance of large vehicles sometimes requires the disassembly of the brake drum, but the brake drum is heavy and requires certain clamping equipment to prevent unnecessary damage caused by sudden drop during disassembly; In the teaching experiment, students also need to remove the brake drum, and then the teacher will explain and teach the internal structure of the brake drum. Students have poor safety awareness and try to avoid the appearance of power supply lines. The above two situations are very dangerous, and there is no need for batch disassembly and assembly. What is needed is a clamping device that is easy to operate and does not require additional power input. It only needs to ensure that the brake drum is stable during the manual disasse...
