Problems solved by technology

[0004] 2. Welding structural parts tooling can use ordinary materials with better welding performance. The advantage is that the production cost is low, but because the welding material has poor heat treatment performance, its hardness and strength are low, and it cannot withstand large dynamic loads. Pressure, hammer Impact force, short service life, plastic deformation will occur in a short service period, affect the assembly quality, easily reduce the assembly accuracy, thus increasing

Example Embodiment

[0057] Example 1:

[0058] Such as figure 1 As shown, in the press-fitting and hammering assembly tooling of embodiment 1 of the present invention, the press-fitting and hammering assembly tooling includes an upper indenter 1, an intermediate body 2 and a lower indenter 3, the upper indenter 1 and the The intermediate body 2 is connected by a thread pair, and the intermediate body 2 and the lower indenter 3 are connected by a thread pair.

[0059] Specifically, the intermediate body 2 includes an upper connecting piece 21, a main pillar 22 and a lower connecting piece 23 welded end to end in sequence. According to the needs of the workpiece to be assembled, both ends of the upper indenter 1 are flat surfaces; the lower indenter 3, the lower connecting piece 23, and the main pillar 22 all have middle through holes, and the lower indenter The cross section of the head 3 is T-shaped.

[0060] The end surface of the upper connecting member 21 welded to the main pillar 202 is the first ...

Abstract

The invention relates to a press fitting and hammering assembling tool which comprises an upper pressing head, a middle body and a lower pressing head. The tool is characterized in that the upper pressing head and the middle body are connected through a thread pair or a flange or a blocking opening. The middle body and the lower pressing head are connected through a thread pair or a flange or a quick-replacing mechanism. The middle body comprises a main guiding column. According to the press fitting and hammering assembling tool, upper pressing heads and lower pressing heads with different types can be selected for combining designing or mounting according to an assembled workpiece and a press fitting tool, and replacing is convenient after damaging.

Description

technical field [0001] The invention relates to the field of mechanical assembly, in particular to a pressing and hammering assembly tool. Background technique [0002] At present, in the machinery industry, when bearings, bushings, bearing bushes, pulleys, sealing rings and other parts are assembled with the shaft or housing parts that match them, due to the large pre-tightening force, the matching precision requirements are relatively high. High, the assembly method usually uses special tooling to apply a certain pressure on the press, press tools or use hammer tools (including copper hammers, iron hammers, copper rods) to hit, in order to achieve the purpose of assembly, while meeting the assembly accuracy requirements , to reduce damage to parts. This kind of tooling is mainly designed and manufactured by two structural forms of integral material or pair welding, but there are many defects in it: [0003] 1. The overall processing tooling can be processed from material...
