Problems solved by technology

When the threaded self-tightening piston head is disassembled, it can only be disassembled by the force of the two fixed pin holes on the upper end of the piston head. At present, there is no disassembly tool for the hydraulic cylinder self-tightening piston head that can quickly and conveniently disassemble the hydraulic cylinder piston head. The use of general tools is low in efficiency and time-consuming, and it is easy to break the positioning pin, deform the positioning pin hole, and slip off the disassembly tool during disassembly, which poses a greater safety hazard to parts and maintenance personnel.
Only two positioning holes can be used on the piston head. Due to the large tightening torque between the piston head and the piston rod, a large torque is required for disassembly, and the depth and diameter of the holes on the piston head are limited. , the disassembly tool cannot be fixed. When a large torque is used and the force is uneven, the disassembly tool will slip off immediately, causing the positioning pin hole to be deformed or personnel injured, which poses a safety hazard and is prone to safety accidents

Embodiment 1

[0016] Embodiment 1: The embodiment of this embodiment is basically as attached Figure 1-3 Shown: a hydraulic cylinder piston head removal device, including a main shaft 5 and a clamping structure, the main shaft 5 is provided with threads, and the clamping structure includes a fixing part 1 and two claws 2, and the two claws 2 and the fixing part 1 One end is fixedly connected, the fixing part 1 is threadedly connected with the main shaft 5, and the cross section of the claw 2 is semi-circular; 2. A plurality of protrusions 8 are provided on the inner surface, a magnetic part 7 is provided on the main shaft 5, and the fixing part 1 is made of a metal material, such as iron. The other end of the fixing part 1 is provided with a handle 4, and the fixing part 1 is rotated by the handle 4, which is easy to operate, convenient and labor-saving. The handle 4 is telescopic, and the telescopic handle 4 can be used to control the use of different forces when rotating, and the operat...

Embodiment 2

[0019] Embodiment 2: The difference between this embodiment and Embodiment 1 is that there is a groove in the claw 2, and there are a fixed block 113, a fixed column 10 and a spring 9 in the groove, and the fixed block is located in the spring 9 and connected to the end of the spring 9. Fixedly connected, the other end of the spring 9 is fixedly connected with the fixed column 10. In this way, when the fixing part 1 is selected, the fixing column 10 contacts and rotates with the piston head, and the force of the claw 2 on the piston head becomes stronger and stronger, and the piston head is clamped tighter, which is convenient for disassembly.

Abstract

The invention discloses a hydraulic cylinder piston head dismounting device which comprises a spindle and a clamping structure. The spindle is provided with a thread. The clamping structure comprises a fixing part and two clamping jaws; the two clamping jaws and one end of the fixing part are fixedly connected; the fixing part is connected with the spindle in a threaded mode; the cross section of each clamping jaw is in a semi-circular shape; the clamping jaws are connected with the fixing part through bolts; a plurality of fixing blocks are arranged on one sides of the clamping jaws; a plurality of protrusions are arranged on the inner surfaces of the clamping jaws; a magnetic piece is arranged on the spindle; and the clamping structure is made of metal materials. The hydraulic cylinder piston head dismounting device can dismount a piston head conveniently.

Description

technical field [0001] The invention relates to the field of hydraulic cylinder manufacturing devices, in particular to a hydraulic cylinder piston head dismounting device. Background technique [0002] The hydraulic cylinder is the executive element in the hydraulic system of construction machinery, mainly composed of cylinder barrel, piston rod, cylinder head, piston head and seal. There are two types of piston heads: one is a nut self-tightening piston head, and the other is a threaded self-tightening piston head. The nut self-tightening piston head can be disassembled by common tools, and the disassembly process is relatively convenient. When the threaded self-tightening piston head is disassembled, it can only be disassembled by the force of the two fixed pin holes on the upper end of the piston head. At present, there is no disassembly tool for the hydraulic cylinder self-tightening piston head that can quickly and conveniently disassemble the hydraulic cylinder pisto...
