Impact adjustable internal puller

Abstract

The invention discloses an impact adjustable internal puller, which comprises a handle rod, an adjusting rod, an impact hammer and a clamping claw component, wherein the handle rod is constituted by a hollow circular tube; the front end of the handle rod is welded with a supporting frame, and the rear end of the handle rod is provided with a handle; the root part of the handle is welded with a fixed disc; the supporting frame consists of a left lug seat and a right lug seat; the impact hammer is sleeved on a polished rod part of the handle rod; the clamping claw component consists of a left pulling claw, a right pulling claw, and a tension slide block and a tension spring which are arranged between the left pulling claw and the right pulling claw; the middle part of the tension slide block is provided with a threaded hole; the adjusting rod is constituted by an iron stick and is penetrated in the handle rod; the front end of the adjusting rod is provided with a threaded head, and the rear end of the adjusting rod is provided with a hexagon nut; the threaded head at the front end of the adjusting rod is screwed with the threaded hole on the middle part of the tension slide block; and the hexagon nut at the rear end of the adjusting rod is pressed against an orifice at the rear end of the handle rod. The product is smooth to operate, convenient and easy to use, fast to disassemble, time-saving and labor-saving and is suitable for disassembling bearings of various specifications.

Description

technical field [0001] The invention belongs to the field of mechanical maintenance tools, and relates to a dismantling tool for bearings and metal sheaths or non-metal sheaths, in particular to an impact-type adjustable inner puller. Background technique [0002] In the maintenance of motor vehicles, it often occurs that the bearing cannot be removed from the outside. In such a situation, the entire wheel hub must be disassembled, and then the bearing must be removed from the inside. The operation is cumbersome, not only time-consuming, labor-intensive, and laborious The bearing and the sheath (bearing seat) are inlaid tight fit, which is not easy to start, and the dismantling project is relatively large, and it is easy to squeeze hands and touch hands, causing personal injury. [0003] For this reason, someone has designed a bearing puller, which is to bend a hook at one end of the crowbar, extend the hook into the hole of the inner ring of the bearing, hook the inner ring...

Problems solved by technology

[0002] In the maintenance of motor vehicles, it often occurs that the bearing cannot be removed from the outside. In such a situation, the entire wheel hub must be disassembled, and then the bearing must be removed from the inside. The operation is cumbersome, not only time-consuming, labor-intensive, and laborious There is a mosaic tight fit between the bearing and the sheath (bearing seat), which is not easy to start with. In addition, the disassembly process is relatively large, and it is easy to squeeze hands and touch hands, causing personal injury

[0003] For this reason, someone has designed a bearing puller, which is to bend a hook at one end of the crowbar, extend the hook into the hole of the inner ring of the bearing, hook the inner ring of the bearing from the outside, and then hold the crowbar with both hands Pull it out to pull the bearing out of the sheath (bearing seat). This method of pulling it out has obvious disadvantages, that is, the strength is not easy to control. The crowbar has only one point of force, the force is unbalanced, and if the force is too large, it is easy to damage the bearing or the sheath
