Detailed Description

When the existing press machine carries out bearing closing processing on the support type assembly, as the appearance of the support type assembly is irregular, referring to fig. 2, the lug plate with the bearing on the lug plate is difficult to be placed into the working surface of the press machine for processing. Aiming at the problem, the application designs the tool for closing up the bearing of the bracket assembly, and the working face of the press machine is moved to the edge of the working table, so that the closing up assembly of the bearing of the bracket assembly is facilitated.

The stent assembly in the present scheme refers to a stent assembly composed of a rod or a rod and other assemblies, such as shown in fig. 2, and the shape of the stent assembly is generally irregular, so that it is difficult to directly close the bearing on the lug thereof by a press.

Referring to fig. 1 to 7, a tooling for a bearing closing-in of a bracket assembly comprises:

the lower backing plate 4 is arranged on a workbench 7 of the press machine; the lower backing plate 4 is a flat plate and mainly plays a role in bottom support; the upper pressing plate 1 is arranged above the lower backing plate 4, and the upper surface of the upper pressing plate 1 is matched with a pressing column 6 of the press; when the press machine works, after a pressing column 6 of the press machine is pressed down to be in contact with the upper surface of the upper pressing plate 1, the bearing is pressed through the upper pressing plate 1 and the stamping die 2 so as to close the bearing. The guide post 3 is vertically arranged between the upper pressing plate 1 and the lower backing plate 4; the guide column 3 serves on the one hand for mounting the punch 2 and the bearing to be machined; on the other hand, the die 2 plays a role in guiding and limiting when being pressed downwards. The die 2 is sleeved on the guide post 3 and is divided into an upper part and a lower part, and the lug plates with the bearings on the support assemblies to be processed are sleeved on the guide post 3 and are positioned between the upper part 21 and the lower part 22 of the die, so that the support assemblies can be positioned in front of the workbench 7 without being placed in a working surface, and only the lug plate parts with the bearings on the assemblies are processed through the die 2, thereby effectively solving the problems in the prior art.

Referring to fig. 3 (a) and (b), in one embodiment of the present application, the upper platen 1 is an L-shaped structure, and includes a pressure-bearing panel 11 and a support plate 12 vertically disposed at one end of the bottom of the pressure-bearing panel 11; a first limit groove 13 matched with the top of the upper part 21 of the punch die 2 is processed on the bottom surface of the front end of the pressure-bearing panel 11. Wherein, the upper surface of pressure-bearing panel 11 is used for cooperating with compression leg 6 of press, and backup pad 12 plays spacing and protection support's effect. The shape of the first retaining groove 13 is adapted to the shape of the top of the upper part 21 of the die 2 so that it can be snapped into it.

Referring to fig. 6 (a) and (b), the upper surface of the rear end of the lower backing plate 4 is provided with a second limiting groove 41 corresponding to the supporting plate 12, and the second limiting groove and the strip-shaped groove are inserted into the lower end of the supporting plate 12 on the upper platen 1, so that the lower end of the supporting plate can be limited when being pressed down, and the upper end of the supporting plate can be prevented from being over-pressed. A third limiting groove 42 matched with the bottom of the lower part 22 of the punching die 2 is processed on the upper surface of the front end of the lower backing plate 4; the third limit groove 42 is shaped to correspond to the bottom shape of the lower part 22 of the die 2. Alternatively, the front end of the lower cushion plate 4 is a convex structure, as shown in fig. 5 (b), and the structure of the shape can avoid the assembly in the process, so that the lug can be attached to the die 2 without interference. Besides, the front end of the lower backing plate 4 is flush with the edge of the workbench 7 or exceeds the edge of the workbench 7; wherein, it is an optimal arrangement to flush, makes the body of subassembly not receive the influence of lower bolster 4 or workstation 7 when processing on the one hand, and on the other hand also can bear the pressure better.

Fig. 4 is a schematic view of the structure of the upper part 21 of the die 2; the upper part 21 and the lower part 22 of the punch die 2 are both provided with through holes 23 which are sleeved on the guide posts 3 along the axial direction, and conical surfaces 24 for closing the bearings are processed at the lower ends of the through holes 23 of the upper part 21 and the upper ends of the through holes 23 of the lower part 22; the small end of the tapered surface 24 communicates with the through hole 23. When pressed down, the bearing completes the closing under the pressure of the conical surfaces 24 of the upper part 21 and the lower part 22. The structure of the lower part 22 of the die 2 corresponds to that of the upper part 21 and will not be described in detail here.

Further, a protection block 5 is placed on the lower backing plate 4, and when a compression column 6 of the press is not pressed down, a gap exists between the protection block 5 and the upper pressing plate 1. When the device works, the upper pressure plate 1 is stressed to incline, and if the inclination is too large, the protective block 5 can be supported below the upper pressure plate, so that parts are prevented from being damaged due to excessive inclination.

Optionally, the upper surface of the upper pressure plate 1 is provided with graduation mark 14. The mark lines are based on the position of the press, which is calculated using the principle of leverage to apply several times the force, e.g., 1 time the force at the top surface 1/2 scale mark 14.

When the device is used, the lower base plate 4 is firstly placed on the press workbench 7, and the protection block 5 is placed on the lower base plate 4; then the support plate 12 on the upper pressure plate 1 is placed into the second limit groove 41 on the lower backing plate 4, the bracket assembly to be processed is lifted, the lug with the bearing passes through the guide post 3, the upper part 21 and the lower part 22 of the punch die 2 clamp the bracket assembly, and the top of the upper part 21 and the bottom of the lower part 22 of the punch die 2 are respectively clamped into the first limit groove on the upper pressure plate 1 and the second limit groove 41 on the lower backing plate 4; and determining the position of the pressure column 6 of the press for applying force according to the pre-calculated scale mark 14, starting the press, and slowly applying the loading force to finish the closing of the bearing.

The above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equally replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present application, and are intended to be included within the scope of the present application.
