Description

Technical Field

[0001] This utility model belongs to the field of tooling components technology, specifically relating to a special clamp for disassembling electromagnetic valves. Background Technology

[0002] Hydraulic solenoid valves are common electrical components in hydraulic control systems. These valves are insert-type connectors with rubber seals installed at the insertion point into the housing. Disassembling the solenoid requires overcoming the friction of these seals. Conventional disassembly methods use both hands and general-purpose tools like screwdrivers. To overcome the frictional resistance between the rubber seals and the inner wall of the housing, the solenoid valve is clamped with one hand and gently pried and shaken with a screwdriver. However, this method carries the risk of scratching the housing and cutting wires. Therefore, a special clamp for disassembling solenoid valves needs to be designed to ensure that the valve is coaxial with the housing hole when pulled out, thus preventing damage to the valve. Utility Model Content

[0003] The purpose of this invention is to address the problems of poor compatibility, poor operability, and poor product protection of conventional tools used for disassembling solenoid valves in the prior art, which cannot meet the requirements for quick and accurate disassembly of solenoid valves. This invention provides a special clamp for disassembling solenoid valves, which is specially designed according to the structure of the solenoid valve to ensure that the solenoid valve is semi-enclosed and fixed in the left-right and front-back directions, thereby avoiding damage to the solenoid valve during disassembly.

[0004] This utility model provides a special clamp for disassembling a solenoid valve, comprising a housing, a screw cap, a limiting screw, a screw, cylindrical pins, and a chuck. The screw cap is installed on the upper end of the housing, and a through hole is provided in the middle of the housing along its axis. The chuck is coaxial with the housing and its upper end passes through the housing and connects to the screw cap. A threaded hole is provided on one side of the housing, in which a limiting screw is installed to restrict the up and down position of the chuck. The upper end of the chuck has an external thread that matches the threaded hole at the screw cap, and the lower end of the chuck has a threaded hole that matches the screw. There are three cylindrical pins, one long cylindrical pin installed at the screw cap, and two short cylindrical pins symmetrically installed at the screw. The screw cap has a through hole.

[0005] Furthermore, the chuck and the screw cap, and the housing and the chuck are connected by their own threads and limiting screws, respectively.

[0006] Furthermore, the chuck has a three-section structure and is integrally molded.

[0007] Furthermore, the lower end of the chuck has a two-lobed arc structure, with a threaded hole on one side of the arc structure and a through hole slightly larger than the outer diameter of the screw on the other side of the arc structure.

[0008] Furthermore, the lower end of the chuck has a two-lobed arc structure with the arc size matching the outer diameter of the solenoid valve, and the bottom end of the chuck is provided with a small boss that matches the groove at the bottom end of the solenoid valve.

[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0012] This utility model discloses a special clamp for disassembling electromagnetic valves, such as... Figure 1-5 As shown, the device includes a chuck 1, a housing 2, a limiting screw 3, a long cylindrical pin 4, a screw cap 5, a screw 6, and short cylindrical pins 7. The screw cap 5 is installed on the upper end of the housing 2. The housing 2 has a through hole along its axis in the middle. The chuck 1 is coaxial with the housing 2 and its upper end passes through the housing 2 and connects to the screw cap 5. The housing 2 has a threaded hole on one side, in which the limiting screw 3 is installed to limit the vertical position of the chuck 1. The upper end of the chuck 1 has an external thread that matches the threaded hole at the screw cap 5. The lower end of the chuck 1 has a threaded hole that matches the screw 6. There are three cylindrical pins, one of which, the long cylindrical pin 4, is installed at the screw cap 5, and two short cylindrical pins 7 are symmetrically installed at the screw 6. The screw cap 5 has a through hole.

[0013] The chuck 1 is connected to the screw cap 5, and the housing 2 is connected to the chuck 1 by its own threads and the limiting screw 3, respectively.

[0014] like Figure 4 As shown, the chuck has a three-section structure and is integrally molded. The lower end of the chuck has a two-lobed arc structure. One arc structure has a threaded hole, and the other arc structure has a through hole slightly larger than the outer diameter of the screw. The lower arc dimension is consistent with the outer diameter of the solenoid valve, and the bottom end of the chuck has a small boss that matches the groove at the bottom end of the solenoid valve, allowing the solenoid valve to be tightly clamped when disassembling it.

[0015] When disassembling the solenoid valve, the bottom boss of the chuck 1 matches the groove of the electromagnet, and then the screw 6 is slowly tightened so that the two arc-shaped structures at the bottom of the chuck 1 slowly come into contact with and clamp the solenoid valve. Then, the screw cap 5 is rotated by the long cylindrical pin 4 to drive the chuck 1 to rise, which in turn drives the solenoid valve clamped by it to overcome frictional resistance and slowly rise until it is completely separated from the inner wall of the product housing, thus completing the disassembly work.
