The following detailed description of the embodiments of the invention is provided.
A bush press-fitting apparatus, as shown in fig. 1 to 4, includes an apparatus stand 1; the lower part of the equipment rack is provided with a workbench 2, and the upper part of the equipment rack is provided with a working arm 3 corresponding to the workbench;
a press-fitting tool 4 is arranged on the workbench, and a press-fitting head 5 is arranged on the working arm corresponding to the press-fitting tool; the press mounting tool comprises a base 6 arranged on a workbench, a positioning seat 7 is arranged on the base, and a central positioning assembly 8 and an auxiliary positioning assembly 9 are arranged on the positioning seat; the press-fitting head comprises a press-fitting seat 10 and a press-fitting driving mechanism 11 for driving the press-fitting seat to move up and down, and a press column 12 is arranged on the press-fitting seat; by way of example, the press-fitting driving mechanism includes a driving cylinder. Generally, the driving cylinder is a pneumatic cylinder, an electric cylinder or a hydraulic cylinder.
The central positioning assembly comprises a central positioning column 13 and auxiliary positioning blocks 14 symmetrically arranged on the periphery of the central positioning column; the auxiliary positioning assembly comprises an auxiliary positioning column 15, the height of the auxiliary positioning column is higher than that of the central positioning column, and a plurality of auxiliary positioning column mounting holes 16 are formed in the positioning column. The upper end of the auxiliary positioning block can be provided with a rubber pad or a nylon pad.
The workpiece placing operation is very simple, the workpiece is placed after the bushing is sleeved on the central positioning column and the auxiliary mounting hole in the workpiece is aligned to the auxiliary positioning hole, and then the workpiece is placed without complex clamping and positioning operation. After the workpiece and the bushing are pressed in place, the auxiliary positioning block abuts against the lower surface of the workpiece, so that the workpiece is guaranteed to have good stability, and meanwhile, the workpiece is prevented from being damaged by direct contact with the workbench.
The central positioning column is arranged on the central supporting block 17, and the height of the upper end surface of the auxiliary positioning block is higher than that of the central supporting block; the height of the upper end face of the auxiliary positioning block is lower than that of the central positioning column. On the pressure equipment frock was laid to the work piece, the auxiliary positioning post inserted in the auxiliary mounting hole of work piece to, can adjust the mounted position of auxiliary positioning post according to the concrete hole site of work piece, so that better supplementary mounting hole that corresponds, the commonality is good, and the auxiliary positioning piece can bear the work piece both sides in addition, ensures that the work piece is reliable and stable, and when the bush pressure equipment, workpiece stability is better, and pressure equipment bush precision is higher, and the rejection rate reduces.
In order to ensure the precision of the pressing head in the pressing process, a guide mechanism 18 is arranged between the pressing seat and the working arm. The specific structure may be that the guide mechanism includes a guide post 19 fixed on the press-fitting seat and a guide sleeve 20 arranged on the working arm corresponding to the guide post, and the guide post and the guide sleeve are in sliding fit. Usually, the guide posts are symmetrically arranged on both sides of the compression post.
The upper surface of the base is provided with a groove 21, the lower end of the positioning seat is provided with a supporting column 22 in sliding fit with the groove, a plurality of buffer parts 23 are arranged between the base and the positioning seat, and the buffer parts are uniformly distributed on the periphery of the supporting column. The bottom end of the supporting column is provided with a plane matched with the bottom of the groove, and the buffer part adopts a spring as an example. The upper end of the buffer piece is fixed at the bottom of the positioning seat, and the lower end of the buffer piece is arranged in the concave hole of the base. Preferably, the distance between the bottom surface of the supporting column and the bottom of the groove is smaller than the compression amount of the buffer.
When carrying out the bush pressure equipment, with the bush suit on central reference column, later lay the pressure equipment frock with the controller casing on, make the auxiliary positioning post insert the supplementary mounting hole of work piece, reach the purpose of location work piece, later utilize pressure equipment actuating mechanism to drive the pressure equipment head and move down, the compression leg supports the work piece, the work piece transmits the positioning seat to the pressure that the bush formed, consequently, in the bush pressure equipment in-process, the bolster forms certain cushioning effect to the base, form the protection to the controller casing, to a certain extent, can avoid the work piece to transship suddenly and cause extrusion deformation.
It should be noted that, the control of the exertion of the buffering performance can be achieved by selecting buffering parts with different elasticity according to the needs, for example, when buffering is needed in the initial stage of press mounting, the buffering parts select products with smaller elasticity (smaller bearing load), and when buffering is needed in the final stage of press mounting, the buffering parts with smaller compressibility and larger elastic acting force (larger bearing load) are selected as far as possible.
In an alternative embodiment, the device rack is provided with a limiting device 21, which includes, by way of example, a distance sensor arranged corresponding to the press-fitting seat, and the distance sensor is electrically connected to a control valve of the press-fitting driving mechanism. When the press-mounting driving mechanism drives the press-mounting head to rise to the set position, the distance sensor feeds back a signal to the control valve, the control valve cuts off the power of the driving cylinder, and the press-mounting head is not lifted continuously. Of course, other limiting devices can be adopted by those skilled in the art as long as the limitation on the displacement of the press-fitting head can be met. Through the stop device who sets up, can effectively avoid pressure equipment head and equipment rack "hard contact", improve equipment's stability, increase of service life.
