Problems solved by technology

[0004] Based on the background technology, there is an unstable connection between the existing hydraulic parts and the connecting valve. When the pressure measuring oil pipe is disassembled, it is easy to cause high-pressure oil injection, which will cause injury to the test personnel or pollute the test environment, and also waste resources. problem, the present invention proposes a quick-change device for hydraulic parts

Embodiment 1

[0024] refer to Figure 1-5 In this embodiment, a quick-change device for hydraulic parts is proposed, including a connecting valve 1 and a hydraulic part main body 2. A cavity 3 is provided on the connecting valve 1, and a positioning column 4 is fixedly connected to the bottom of the hydraulic part main body 2. The bottom of the positioning column 4 runs through the top of the connecting valve 1 and extends into the cavity 3. A sliding plate 5 is slidably connected in the cavity 3. The bottom of the positioning column 4 is in contact with the top of the sliding plate 5. Both sides of the cavity 3 Two first rotating rods 6 are rotatably connected on the inner wall, and a second rotating rod 7 is connected to the first rotating rod 6. The fixed sleeve on the second rotating rod 7 is provided with a gear 8, and two tooth racks 9 are slidably connected to each other on the top inner wall of the cavity 3, the gear 8 is meshed with the tooth rack 9, and the sides of the two tooth ...

Abstract

The invention belongs to the field of detecting equipment and particularly relates to a hydraulic piece table position fast changing device directing at the problems that an existing hydraulic piece and a connection valve are instable in connection, when a pressure measuring oil pipe is disassembled, high-pressure oil injection can be caused very easily, injuries are caused to test personnel or the test environment is polluted, and meanwhile resource waste is also caused. Now the following scheme is put forwards, the hydraulic piece table position fast changing device comprises a connection valve and a hydraulic piece body; the connection valve is provided with a cavity; and a positioning column is fixedly connected to the bottom of the hydraulic piece body. The hydraulic piece table position fast changing device is reasonable in structure, and due to fast fixing on the hydraulic piece body, the oil leaking problem generated between the connection valve and the hydraulic piece body canbe effectively solved; a first rotating shaft is rotated so that two sealing plates can be used for sealing a through pipe, it can be effectively prevented that when a pressure measuring oil pipe isdisassembled, high pressure oil injection is caused, the test personnel are injured or the test environment is polluted, meanwhile resources are saved, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a quick-change device for hydraulic parts. Background technique [0002] Hydraulic components are all components used in hydraulic systems such as hydraulic pumps, hydraulic motors, hydraulic cylinders, hydraulic valves, and boosters. [0003] At present, some hydraulic parts test benches use threaded joints, quick-change joints and oil pipes to connect with the test bench, but the existing hydraulic parts and connecting valves are not connected stably, because the pressure during the hydraulic parts test is between 35-50bar During the disassembly of the connecting oil pipe in the valve body of the existing hydraulic parts, it is easy to cause high-pressure oil injection, which will cause injury to the test personnel or pollute the test environment, and will also waste resources. Therefore, we propose a hydraulic part platform A quick change device is used to solve t...
