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 the production cost
If high-carbon steel or alloy steel with better heat treatment performance is used for welding, due to the poor performance of the weld seam, it is easy to crack, the service life is short, and the cost of raw materials is high, which will also result in high costs.
[0005] 3. Both of the above two structures have the problems that the vulnerable parts are not suitable for replacement, it is not easy to maintain, and it is difficult to replace two or more kinds of tooling.

Embodiment 1

[0058] Such as figure 1 As shown, in the pressing and hammering assembly tooling of Embodiment 1 of the present invention, the pressing and hammering assembly tooling includes an upper pressing head 1, an intermediate body 2 and a lower pressing head 3, and the upper pressing head 1 and the described The intermediate body 2 is connected by a pair of threads, and the intermediate body 2 is connected with the lower pressing head 3 by a pair of threads.

[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 pressing head 1 are flat; The cross section of the head 3 is T-shaped.

[0060] The end face of the upper connector 21 welded with the main pillar 202 is the first end face 211, and the first end face 211 is provided with a circular boss 212 (for the convenience of manufacturing and pro...

Embodiment 2

[0065] Such as figure 2 As shown, in the pressing and hammering assembly tooling of Embodiment 2 of the present invention, the pressing and hammering assembly tooling includes an upper pressing head 1, an intermediate body 2 and a lower pressing head 3, and the upper pressing head 1 and the described The intermediate body 2 is connected through a seam, and the intermediate body 2 is connected with the lower pressing head 3 through a thread pair.

[0066] 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. The difference from Embodiment 1 is that one end of the upper connector 21 connected to the upper indenter 1 is set as a first installation cavity 214, and a stopper 213 is opened on the wall of the first installation cavity 214 , a ring groove 102 is provided at a position corresponding to the notch 213 on the upper pressing head 1 . The upper indenter 1 extends into ...

Embodiment 3

[0068] Such as image 3 As shown, in the press-fitting and hammering assembly tooling of Embodiment 3 of the present invention, the press-fitting and hammering assembly tooling includes an upper pressing head 1, an intermediate body 2 and a lower pressing head 3, and the upper pressing head 1 and the described The intermediate body 2 is connected by a pair of threads, and the intermediate body 2 is connected with the lower pressing head 3 by a pair of threads.

[0069] Specifically, the intermediate body 2 includes a main post 22, and the two ends of the main post 22 are provided with external threads.

[0070] One end of the upper indenter 1 connected to the main post 22 has a third installation cavity 105, and an internal thread cooperating with the external thread of one end of the main post 22 is provided in the third installation cavity 105, The external thread and the internal thread form a thread pair, and the other end of the upper pressing head 1 can be set according...

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...
