Abstract

The utility model discloses a tool assembly for assembling a machine tool part bearing. The hammer is composed of a handle (1), a hammer head (2), a handle (3), a ferrule (4) and a pressing block (5). The handle (1) and the hammer head (2) are integrated, the handle (3) and the ferrule (4) are integrated, a round hole is formed in the front part of the ferrule (4), a round table is arranged at the tail part of the pressing block (5), the round hole in the front part of the ferrule (4) is in interference fit with the round table at the tail part of the pressing block (5), and the handle (3), the ferrule (4) and the pressing block (5) are integrated. The bearing is characterized by being moderate in hardness, only transmitting force without damaging the bearing and being simple in structure.

Description

Technical Field

[0001] The utility model relates to the field of assembly of machine tool parts. Background Art

[0002] In mechanical manufacturing, many parts of machine tools have bearings. Assembling bearings is a necessary task. The quality of bearing assembly directly affects the performance of machine tool parts. However, there are no tools on the market specifically for assembling bearings. Utility Model Content

[0003] The utility model is based on the fact that there is no tool for assembling bearings specifically on the market, and the bearings are usually directly hit with lead blocks. Due to uneven force on the bearings, the bearings are often damaged. Therefore, a relatively soft copper material is proposed as a tool, which contacts the end face of the bearing and only transmits force without damaging the bearing, and has a simple structure.

[0004] A tool assembly for assembling a bearing of a machine tool component, comprising: a first handle (1), a hammer head (2), a second handle (3), a ferrule (4), and a pressing block (5), wherein the first handle (1) and the hammer head (2) are integrated, the second handle (3) and the ferrule (4) are integrated, the front of the ferrule (4) has a round hole, the rear of the pressing block (5) has a round table, the front round hole of the ferrule (4) and the rear round table of the pressing block (5) are interference fit, the second handle (3), the ferrule (4), and the pressing block (5) are integrated, and the pressing block (5) is a stepped cylindrical The small cylinder matches the inner ring of the ferrule (4) and is an interference fit. The material is red copper, and the outer diameter is smaller than the outer diameter of the bearing. The front end is provided with a countersunk hole (8) on which a through venting groove (9) is provided. The first handle (1) is cylindrical and can be held by hand without swelling and is comfortable. The hammer head (2) is cylindrical. The materials of the first handle (1) and the hammer head (2) are 45 steel. The second handle (3) is cylindrical and can be held by hand without swelling and is comfortable. The ferrule (4) is annular. The materials of the second handle (3) and the ferrule (4) are 45 steel. BRIEF DESCRIPTION OF THE DRAWINGS

[0005] Figure 1 A schematic diagram of a tool assembly for assembling a bearing of a machine tool component. DETAILED DESCRIPTION

[0006] The following is a further description of a tool assembly for assembling a bearing of a machine tool component, which comprises: a first handle (1), a hammer head (2), a second handle (3), a ferrule (4), and a pressing block (5). The first handle (1) and the hammer head (2) are integrated, the second handle (3) and the ferrule (4) are integrated, the front of the ferrule (4) has a round hole, the rear of the pressing block (5) has a round table, the front of the ferrule (4) and the rear of the pressing block (5) are interference fit, and the second handle (3), the ferrule (4), and the pressing block (5) are integrated.

[0007] The method of using the hammer is as follows: holding the bearing in one hand and holding the second handle (3) in the other hand, and gently and evenly knocking the end face of the bearing; after the bearing is inserted into the hole of the housing, the hand is withdrawn, and the first handle (1) is held again, and the end of the second handle (3) is evenly knocked with the hammer head (2) to press the bearing into the position in the hole of the housing.
