Abstract
The utility model discloses a device is riveted to round pin axle pressure, the device include crimping tong platform, the fixed tray of work piece, with crimping tong platform fixed connection's press and have the work piece of round pin axle, the fixed tray of work piece passes through the fixed axle and is connected with the rotation of crimping tong platform, the last locating pin that is equipped with of crimping tong platform, the work piece is fixed on the fixed tray of work piece, install the crimping on the press and dash the round pin. The corresponding positions of the pin shaft and the compression joint punch pin can be rapidly determined through the fixed shaft and the positioning pin, and the compression joint punch pin extrudes the pin shaft through the press machine to enable the pin shaft to expand in the mounting hole. By using the device, the operation of installing the workpiece on the production line can be realized, the potential safety hazard in the operation process is eliminated, and the consistency and the product quality of the product are improved.
Description
Technical Field
The utility model belongs to the technical field of metal stamping, in particular to press and rivet device suitable for round pin axle
Background
In the existing installation and production of the extractor, the pin shaft riveting method is to use a hammer to knock a punch pin to expand a pin hole so as to fix a workpiece. However, the method has the following disadvantages: firstly, an operator holds the impact pin by hand and then uses a hammer to knock the impact pin, so that the safety problem of the operation of knocking the hand exists; secondly, very large noise is generated during knocking, the desktop vibrates greatly, other personnel of a production line can be influenced, and the conventional pin shaft is arranged in other areas and cannot be operated on the production line in order not to influence the operation of the personnel on the production line; the knocking force is different, so that the pin holes of the pin shafts are not expanded uniformly, the products processed in the same batch are inconsistent, and the quality of the products cannot be ensured well; the shell moves or shakes on the table top due to the existence of a reverse force during knocking, and friction and impact are formed between the shell and the cushion block and the table top, so that the shell is easily scratched or gouged; fifthly, aligning of the punching pin and the pin hole is manually aligned during knocking, and the operation efficiency is low. Therefore, in order to realize the operation of installing the extractor on the production line and improve the power supply production efficiency and the product quality, a new production flow, an assembly method and a device are urgently needed.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a rivet pressing device for round pin axle can realize the operation of installation work piece on the assembly line, eliminates the potential safety hazard in the operation process, improves the uniformity and the product quality of product simultaneously.
The technical scheme of the utility model is specifically as follows:
the utility model provides a round pin axle is pressed and is riveted device, includes crimping tong platform, the fixed tray of work piece, press and has the work piece of round pin axle, be equipped with fixed axle and locating pin on the crimping tong platform, the fixed tray of work piece passes through the fixed axle and is connected with the rotation of crimping tong platform, fixedly connected with is used for the fixed block of fixed work piece and round pin axle push down the cushion on the fixed tray of work piece, be connected with the crimping on the press and dash the round pin.
Further, in the above technical solution, the press machine includes a pressing handle and a connecting piece, and the pressing punch pin is movably connected with the connecting piece; and a rubber layer is arranged on the surface of the fixing block.
The utility model has the advantages that: the device can be directly operated on flowing water, has no noise during operation, does not need to be held by hand during crimping, has no potential safety hazard and is simple to operate. The device is provided with the limiting device, so that the pin punching and pin hole do not need to be aligned during operation, and the operation efficiency is improved. The workpiece shell can not move or jump during operation, and the fixed block of the workpiece shell is protected by rubber, so that the phenomenon of damaging the surface of the shell during operation is avoided. After the device is used for compression joint, the pin shaft holes are compressed and expanded, and are completely and precisely attached to the corresponding mounting holes, the expanded appearance is consistent, and the product quality and consistency are improved. The device is short in time consumption during operation, can be directly integrated into the beat of an assembly station, enables the whole operation process to be on a production line, and improves the whole production efficiency of the production line.
