Abstract

The utility model discloses a mounting tool for a sealing ring on a piston of an oil cylinder. The mounting tool comprises a three-claw chuck (1), upper pushing rings (2), expansion blocks (4) and a working table (10). The three-claw chuck (1) is mounted on the working table (10), at least three expansion blocks (4) are uniformly welded on the outer wall of the top of the three-claw chuck (1) to form an expansion ring, and the upper pushing rings (2) are sleeved on the expansion blocks (4), and thus the mounting tool is formed. When the three-claw chuck of the mounting tool is clamped on a limiting block, the three expansion blocks do not interfere and are kept in an original state. The limiting block is used for internal positioning and the upper pushing ring is used for external positioning, the travels of the expansion blocks are effectively controlled so that the sealing ring is not damaged by overlarge total radial deformation in a mounting process. The mounting tool disclosed by the utility model has the advantages of simple structure, convenience in operation, efficient operation and long service life.

Description

The erecting tools of the sealing ring on the oil cylinder piston

Technical field

The utility model relates to instrument, is specifically related to the erecting tools of the sealing ring on a kind of oil cylinder piston.

Background technology

At present, in tractor lifter hydraulic cylinder assembly, conical surface mandrel method is often adopted in the installation of the sealing ring on the piston, is placed on conical surface mandrel on the piston earlier, then is contained in sealing ring on the conical surface mandrel, passes along the mandrel conical surface sealing ring to piston with instrument again; Because the sectional area of conical surface mandrel is little, rigidity is big, and afterburning difficulty is installed, and the application of force is difficult for accomplishing circumferentially to be uniformly distributed with, and is prone to cause that sealing ring damages; In addition, this installation method efficient is low, and effort is difficult to satisfy the production demand; Certainly, also have some other installation methods, but all cut both ways.

Summary of the invention

The purpose of the utility model is: design the erecting tools of the sealing ring on a kind of oil cylinder piston, this erecting tools is simple in structure, and is easy to use, uniform force application, high efficiency.

The technical solution of the utility model is: this erecting tools comprises scroll chuck, last throw-out collar, piece and workbench expand; Scroll chuck is installed on workbench; On the top exterior walls of scroll chuck, at least evenly weld three bloated pieces and form tensioner ring; Cover connects throw-out collar on the piece that expands, whole formation erecting tools.

Wherein, limited block is installed on workbench, limited block is positioned at the centre bit of scroll chuck.

Wherein, crank is installed on scroll chuck.

Wherein, handle installation on last throw-out collar.

Wherein, establish spiral chute, on the piece that expands, pin is installed, the operation that pin cooperates spiral chute control to go up throw-out collar at the inwall of last throw-out collar.

During work, rotate crank earlier, three bloated pieces are moved to the center of scroll chuck, scroll chuck snaps into limited block, sealing ring is placed on the male half coupling of the piece that expands; The crank that then reverses makes the piece that expands outwards move to throw-out collar, is placed on the targeting part of piston on the inner conical surface of tensioner ring to locate; Last turning handle, last throw-out collar moves on pinning by its spiral chute, and moves on the drive sealing ring, in sealing ring mobile piston mounting groove.

The utility model beneficial effect: 1,Utilize this erecting tools that sealing ring is installed, simple to operate, convenient efficient; When 2, scroll chuck snaps into limited block; Three bloated pieces must not interfere and keep reset condition, limited block to play the effect of interior location, and last throw-out collar plays the effect of outside fix; Effectively controlled the stroke of bloated piece, guaranteed that sealing ring can not damage because of radially total deformation is excessive in installation process.

Description of drawings

Fig. 1 will seal snare to the piece male half coupling sketch map that expands for scroll chuck is tightened to limited block.

Fig. 2 unclamps the supreme throw-out collar sketch map of scroll chuck.

Move sketch map on the throw-out collar on the counterclockwise driving handle of Fig. 3.

The last throw-out collar of Fig. 4 drives sketch map in sealing ring to the piston mounting groove.

Among the figure: 1 scroll chuck, throw-out collar on 2,3 sealing rings, 4 pieces that expand, 5 pistons, 6 handles, 7 limited blocks, 8 cranks, 9 pins, 10 workbench.

The specific embodiment

Shown in Fig. 1-4; This erecting tools comprises scroll chuck 1, last throw-out collar 2, piece 4 and workbench 10 expand; Scroll chuck 1 is installed on workbench 10; On the top exterior walls of scroll chuck 1, at least evenly weld three bloated pieces 4 and form tensioner ring, cover connects throw-out collar 2 on bloated piece 4, whole formation erecting tools.

Wherein, limited block 7 is installed on workbench 10, limited block 7 is positioned at the centre bit of scroll chuck 1.

Wherein, crank 8 is installed on scroll chuck 1.

Wherein, handle installation 6 on last throw-out collar 2.

Wherein, establish spiral chute, pin 9 is installed on bloated piece 4, the operation that pin 9 cooperates spiral chute control to go up throw-out collar 2 at the inwall of last throw-out collar 2.

During work, rotate crank 8 earlier, three bloated pieces 4 are moved to the center of scroll chuck 1, scroll chuck 1 snaps into limited block 7, sealing ring 3 is placed on the male half coupling of the piece 4 that expands; The crank 8 that then reverses makes the piece 4 that expands outwards move to throw-out collar 2, is placed on the targeting part of piston 5 on the inner conical surface of tensioner ring to locate; Last turning handle 6, last throw-out collar 2, and move on the drive sealing ring 3 along moving on the pin 9 by its spiral chute, in sealing ring 3 mobile piston mounting grooves.
