Problems solved by technology

[0002] The puller is widely used in machinery. It can disassemble round workpieces such as pulleys, gears, bearings, etc. in various mechanical equipment. It has the advantages of convenient use and stable disassembly. Although the size of the horse can be adjusted within a certain range, the angle of the hook part relative to the workpiece will change after the size adjustment, resulting in weak clamping and effective disassembly.

Embodiment Construction

[0017] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0018] Such as figure 1 As shown, the puller corresponding to a preferred embodiment of the present invention is used to disassemble the ring-shaped workpiece 7 from the shaft 8, and the workpiece 7 can be workpieces such as bearings, pulleys and gears. The puller includes a body 1 , an extruding screw 2 and a hook 3 .

[0019] The body 1 includes at least two ends 1a that work together to clamp the workpiece 7. The body 1 also includes a connecting portion 1b connecting each end. The extruding screw 2 is arranged at the center of the connecting portion 1b. When the puller clamps the workpiece 7 , the axis of the extruding screw 2 is basically consistent with the axis of the workpiece 7 . In this embodiment, the body 1 is U-shaped, which includes two opposite end portions 1a.

Abstract

The invention discloses a puller. The puller comprises a body (1) and an extrusion screw (2) which is in threaded connection with the body (1), the body (1) comprises at least two ends (1a), and the ends (1a) are used for hooking an annular workpiece (7). The puller is characterized in that hooking parts (3) are movably connected to the ends (1a), and can move in the axial direction of the workpiece (7). The size of the puller can be adjusted according to the size of the workpiece; meanwhile, the angle of a hooking portion and the workpiece cannot be changed, and the puller is convenient to use and high in reliability.

Description

technical field [0001] The present invention relates to a puller. Background technique [0002] Pullers are widely used in machinery. They can disassemble round workpieces such as pulleys, gears, and bearings in various mechanical equipment. They have the advantages of convenient use and smooth disassembly. Although the size of the horse can be adjusted within a certain range, the angle of its hook portion relative to the workpiece will change after the size is adjusted, resulting in weak clamping and effectively dismounting. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned defects in the prior art, and provide a puller, the clamping distance of which can be easily adjusted according to the size of the workpiece, and the angle of the hook will not change. [0004] In order to achieve the purpose of the above invention, the present invention adopts the following technical solution: a puller, including a body, an extrus...
