Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a pulling claw assembly suitable for a retreat machine. Background Art

[0002] A bearing removal machine is a device used to remove bearings. It typically uses hydraulic or mechanical principles to apply force to push the bearing out of the shaft or bearing seat. It can improve the efficiency and safety of bearing removal and reduce the difficulty and risks of manual operation.

[0003] The existing claws have low compatibility. When disassembled, the claw heads will not form a complete circle, which reduces the strength.

[0004] It is hoped to provide a pulling claw assembly suitable for a retreat machine that can solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a pulling claw assembly suitable for a retreating machine, wherein a pulling claw stopper device is added to a conventional pulling head to increase the strength.

[0006] In order to achieve the purpose of the above utility model, a claw assembly suitable for a retreat machine includes two claws and two claw stops;

[0007] The facing ends of the two pulling claws are provided with a semicircular groove, and the other ends of the two pulling claws are provided with a plurality of through holes;

[0008] Both ends of the side with the semicircular groove on the two pulling claws are provided with mounting grooves;

[0009] The two pulling claws are respectively fixed to the two mounting slots of any pulling claw by screws.

[0010] Preferably, the end of the semicircular groove on the pulling claw has an arc-shaped transition area.

[0011] Preferably, the interior of the semicircular groove has a reinforcing rib protrusion.

[0012] The utility model is a claw assembly suitable for retreating machines, which has the following advantages compared with the prior art:

[0013] (1) A claw block device is added to the conventional pull head to increase the strength; the wheel axle surface is not easily worn; the bearing force is evenly distributed;

[0014] (2) Simple structure and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is a schematic diagram of the structure of a pull claw suitable for a retreat machine in this embodiment. Figure 1 ;

[0016] Figure 2 This is an exploded view of a claw assembly suitable for a retreat machine in this embodiment.

[0017] Figure 3 This is a schematic diagram of a claw assembly suitable for a retreat machine according to the embodiment of the present invention, which is installed on the retreat machine in a non-working state;

[0018] Figure 4 This is a schematic diagram of the working state of a pulling claw assembly suitable for a retreat machine of this embodiment installed on the retreat machine. DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figure 1 and Figure 2 As shown, a pulling claw composition suitable for a retreat machine includes two pulling claws 1 and two pulling claw blocks 2.

[0022] The two claws 1 have a semicircular groove 3 at one end facing each other, and a plurality of through holes 4 are provided on the other end of the two claws 1 ; both ends of the side with the semicircular groove 3 on the two claws have mounting grooves 5 .

[0023] The two pulling claws 1 are fixed to the two mounting slots 5 of any one pulling claw 1 by screws 6 , respectively.

[0024] like Figure 3 and Figure 4 As shown, during operation, the claw stopper 2 is fixed to the upper and lower ends of the claw 1 by screws 6. During operation, the two claws 1 are embraced together, and the claw stopper 2 is inserted into the other claw. During disassembly, the force is concentrated on the entire circle, the strength is more reliable, the axle surface is not easily worn, and the bearing is evenly stressed.

[0025] In this embodiment, the end of the semicircular groove 3 on the pulling claw 1 has an arc-shaped transition area 7 to avoid stress concentration and better clamp the bearing to be disassembled.

[0026] In this embodiment, the interior of the semicircular groove 3 has a reinforcing rib protrusion 8, which effectively improves the strength of the claw assembly.

[0027] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
