Self-adaptive assembling device for paired press fitting of bearings

Abstract

The invention discloses a self-adaptive assembling device for paired press fitting of bearings. The mechanical portion of the self-adaptive assembling device for paired press fitting of the bearings comprises a screw guide rail module, mechanical claw assemblies, a self-movement guide rail sliding block assembly and a resetting cylinder assembly. The lower portion of the self-movement guide rail sliding block assembly is fixedly connected with the screw guide rail module, and the rear portion of the self-movement guide rail sliding block assembly is fixedly connected with the resetting cylinder assembly. The mechanical claw assemblies are fixedly connected to sliding blocks of the screw guide rail module. The screw guide rail module is driven by a servo motor and used for driving the mechanical claw assemblies to move. The mechanical claw assemblies are used for paired grabbing and installing of the bearings. The self-movement guide rail sliding block assembly is used for achieving mechanical self-adaption of the assembling process. The self-movement guide rail sliding block assembly can be driven to return to an original position by the resetting cylinder assembly. According to the self-adaptive assembling device for paired press fitting of the bearings, the bearings can be grabbed in pairs and press-fitted in pairs; automatic centering can be achieved; the device can be adaptive to bearings and parts of a certain dimension range; and self-adaptive dynamic adjustment can be achieved by relying on mechanical structure innovation to design the press fitting process of the bearings.

Description

technical field [0001] The invention relates to an self-adaptive assembly device for paired press-fitting of bearings. The assembly device can be used for automatic grasping and assembly of bearings, and belongs to the technical field of automatic assembly. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. As mechanical supports, they are widely used in shafting mechanisms with rotary motion, which can effectively reduce the friction coefficient in the rotation of mechanical rotating bodies and ensure their rotation accuracy. Due to the huge application of bearings in industrial products, the low efficiency of manual assembly, high cost and difficulty in ensuring the consistency of assembly quality, more and more factories use automation technology for bearing assembly.

Problems solved by technology

Due to the huge application of bearings in industrial products, the efficiency of manual assembly is low, the cost is high, and the consistency of assembly quality is difficult to guarantee. More and more factories use automation technology for bearing assembly.

[0003] When carrying out automatic assembly of bearings, it is necessary to pay attention to the adaptation of the bearing size. Mechanical equipment generally contains a variety of bearings, and some bearings are similar in size. It is necessary to design a set of assembly devices to adapt to a variety of bearings of similar sizes; attention should be paid to the bearings and bearing holes. Alignment problem, if the two are not aligned, the bearings will not fit in, and the automation equipment will be destroyed if the two are not aligned; it is necessary to solve the problem that the bearings on both sides are not completely synchronized when the bearings are assembled in pairs. The existing bearing installation mechanism is performing bearing assembly. When entering the hole, it often depends on the feedback information of the displacement sensor or pressure sensor for control, which requires high precision and real-time performance of the sensor, and the sensor needs to continuously feed back force position information, and the controller analyzes the feedback force position information After processing, the actuator will be controlled for the next step, and the efficiency of bearing assembly needs to be further improved
