Problems solved by technology

[0004] (1) Due to the different dimensions of the outer circles of the disassembled parts, different pullers need to be purchased, and the cost of maintenance tools is high. Some pullers of certain specifications are used less frequently and idle for a long time, resulting in a waste of resources;
[0005] (2) When disassembling the bearing in the hole, the pull claws of the puller in the prior art cannot be installed, nor can the bearing in the hole be disassembled;
[0006] (3) When the disassembled part has an arc-shaped appearance, the pull claws of the prior art puller cannot be fixed for use;
[0007] (4) When the parts to be disassembled have irregular shapes and need to be drawn eccentrically, the pullers of the prior art cannot meet the requirements for use

Embodiment 1

[0032] Embodiment one, such as figure 1 As shown, the disassembly of the supporting roller: the large shaft section of the screw jack 2 is set on the left side of the fixed faceplate 1, and the threaded section of the screw jack 2 passes through the center of the supporting roller 4 and is fixed; one end of the four tie rods 3 Fix the left side of the waist-shaped hole of the fixed faceplate 1 with nuts respectively, and the other ends of the four tie rods 3 are fixed with nuts on the right side of the side plate of the roller 4;

[0033] Pull rod 3 also can select two combination use or three combination use.

Embodiment 2

[0034] Embodiment two, such as figure 2 As shown, the disassembly of the inner and outer rings of the bearing: the large shaft section of the screw jack 2 is set on the left side of the fixed faceplate 1, and the threaded section of the screw jack 2 passes through the center of the bearing 6 and then fixed; one end of the four tie rods 3 is respectively used The nut is fixed on the left side of the waist-shaped hole of the fixed faceplate 1, and the other ends of the four pull rods 3 are all provided with pull claws 5, and the pull claws 5 are arranged on the outer ring of the bearing 6, and the hook surface of the pull claw 5 is in contact with the outer ring of the bearing 6. right end face contact;

[0035] Pull rod 3 also can select two combination use or three combination use.

Embodiment 3

[0036] Embodiment three, such as image 3 As shown, the disassembly of the tensioning wheel: the two ring plates of the fixed faceplate 1 are provided with hooks of the chain assembly 7, and the chain of the chain assembly 7 is connected to the hook after bypassing the rim of the tensioning wheel 8; The large shaft section of 2 is set on the left side of the fixed faceplate 1, and the threaded section of the screw jack 2 passes through the axis of the tensioning wheel 8 and is fixed;

[0037] The ring plate of the fixed face plate 1 can also be selected to use in combination of three hanging chain assemblies 7 or four hanging chain assemblies 7 in combination.

Abstract

The invention discloses a multifunctional puller. A fixing disc is provided with a group of four elongated holes distributed uniformly and peripherally and a group of three elongated holes distributed uniformly and peripherally, and the group of four elongated holes and the group of three elongated holes share one elongated hole which is formed in a boss A; the elongated hole which forms a 180-degree angle with the shared elongated hole is formed in a boss B; the elongated hole which forms a 90-degree angle with the shared elongated hole and the elongated hole which forms a 120-degree angle with the shared elongated hole are formed in a boss C; elongated hole which forms a -90-degree angle with the shared elongated hole and the elongated hole which forms a -120-degree angle with the shared elongated hole are formed in a boss D; the boss A is respectively in ring plate connection with the boss C and the boss D. The multifunctional puller has the advantages of structural reasonability, suitableness for various dimension requirements, functional diversification, wide application range, saving of maintenance cost and avoiding of resource waste.

Description

technical field [0001] The invention belongs to the technical field of mechanical maintenance and relates to a multifunctional puller. Background technique [0002] The puller in the prior art is a tool often used in mechanical maintenance. Its function is to disassemble the pulley, sprocket, bearing, bushing, etc. fastened on the shaft. The puller is composed of a rotary handle, a screw ejector rod and a pull claw. . [0003] In the maintenance of agricultural machinery, especially harvesters, there are the following technical deficiencies: [0004] (1) Due to the different dimensions of the outer circles of the disassembled parts, different pullers need to be purchased, and the cost of maintenance tools is high. Some pullers of certain specifications are used less frequently and idle for a long time, resulting in a waste of resources; [0005] (2) When disassembling the bearing in the hole, the pull claws of the puller in the prior art cannot be installed, nor can the be...
