Description

Technical Field

[0001] This utility model relates to the field of disassembly technology, and in particular to a two-claw puller. Background Technology

[0002] Existing patent publication number (CN218082544U) discloses a puller device, including a screw, a crossbeam, pull rods, pull claws, a longitudinal fixing screw, and a transverse fixing screw. The screw is installed on the crossbeam through a screw hole. The puller device includes two pull rods and two pull claws. Both pull rods are detachably connected to the crossbeam. One pull claw is detachably connected to one end of one pull rod, and the other pull claw is detachably connected to one end of the other pull rod. A square hole is provided at one end of each pull rod. The crossbeam is inserted into the square hole of the pull rod, and the distance between the two pull rods is adjusted by moving the crossbeam within the square hole. This utility model's puller device can adjust the distance between the pull rods and facilitates the replacement of pull claws, and is safe and reliable.

[0003] However, the above-mentioned patent requires the removal of four screws when replacing the pull claw, which is a cumbersome process, and the above-mentioned patent can only remove the outer ring of the bearing. Utility Model Content

[0004] This utility model provides a puller device to solve the technical problems mentioned in the background art, such as the need to remove four screws when replacing the puller using the above-mentioned patent, which makes the process cumbersome, and the fact that only the outer ring of the bearing can be disassembled.

[0005] A two-clawed pulling horse, comprising; A crossbar with a screw hole in the middle and a screw threaded to the crossbar. Pull claws are inserted at both ends of the crossbar. Adjustable fasteners are also provided on the pull claws. After the pull claws are completely disengaged from the crossbar, replacement pull claws can be inserted on the crossbar. The replacement pull claws are also provided with adjustable fasteners. The lower ends of the pull claws and the replacement pull claws have a transverse protrusion structure for hooking the bearing end face.

[0006] Preferably, the pull claw has a screw hole on its side and a sliding groove on its upper end. The sliding groove on the pull claw is slidably inserted into the crossbar. A screw is threaded into the screw hole. Tightening the adjusting screw causes its front end to abut against the side of the crossbar for fixation.

[0007] Preferably, a protruding flange is fixedly provided on the side wall of the pull claw, and the inner wall of the flange is flush with the inner wall of the slide groove. The flange increases the contact and clamping surface between the inner wall of the slide groove and the crossbar, thereby improving the insertion stability of the pull claw relative to the crossbar.

[0008] Preferably, the replacement pull claw has a screw hole on its side and a sliding groove at its upper end. The sliding groove on the replacement pull claw is slidably inserted into the crossbar. An adjusting screw is threaded into the screw hole on the replacement pull claw. After the adjusting screw is tightened, the replacement pull claw is fixed on the crossbar.

[0009] Preferably, the upper sidewall of the replacement pull claw is fixedly provided with a flange, the inner wall of the flange is flush with the inner wall of the slide groove, thereby increasing the contact surface length between the slide groove and the crossbar after the slide groove is inserted into the crossbar, and improving the stability of the replacement pull claw insertion.

[0010] Preferably, a flange ring with an upward protrusion is fixedly provided at the middle part of the crossbar with the screw hole of the crossbar as the center. The flange ring forms an upward open annular groove. After the screw is threadedly connected to the crossbar, lubricating oil is added to the annular groove of the flange ring. Then, the screw is rotated once relative to the crossbar so that the lubricating oil is evenly applied to the screw thread. This facilitates smooth disassembly and effectively improves the service life of the device.

[0011] The advantages and positive effects of this utility model are: Compared to existing patented technologies that can disassemble bearings of different sizes and shapes within a certain range by replacing the pull claws or adjusting the pull claw spacing, this technology is more convenient as it only requires manually loosening two adjusting screws.

[0012] Compared to existing technologies, this method can change the insertion direction of the pull claw, causing the hook at the lower end of the pull claw or the replacement pull claw to face outward, thereby allowing it to enter from the inner ring of the bearing for disassembly.
