Technical Field

The invention belongs to the technical field of processing devices, and particularly relates to a demagnetization and fine grinding integrated structure of a rocker arm shaft.

Background

The rocker shaft has the function of fixing the rocker arm, the rocker arm is a lever, and the rocker arm shaft is a fulcrum. The rocker arm can rotate a certain angle around the rocker shaft.

At present, the production process of the rocker arm shaft is ordered into fine grinding of an excircle, burr brushing, demagnetization, sorting and the like. The demagnetization process after the excircle is finely ground is characterized in that the parts collide with each other to cause poor appearance due to one-time turnover, the local edge of the intersection line is protruded, the assembly and the use are directly influenced, and the demagnetization process belongs to poor functions.

The existing defective rocker shaft removal is a sorting process after demagnetization, and the existing defective rocker shaft is subjected to manual full inspection to identify appearance defects such as burrs, bumps and the like. The existing process is manual selection, is influenced by personal subjective factors of operators, and still has defective products due to different working environments due to understanding of selection standards.

In view of the above, the present invention provides an integrated structure for demagnetizing and fine grinding of a rocker arm shaft, which is improved in view of the conventional structure and drawbacks, and is intended to achieve a more practical purpose.

Disclosure of Invention

In order to solve the technical problems, the invention provides an integrated structure for demagnetizing and fine-grinding a rocker arm shaft, which aims to solve the problems that when the demagnetizing process is carried out after the outer circle of the existing rocker arm shaft is finely ground, the parts collide with each other once again, the appearance is poor, the local edge at the intersection line is raised, and the assembly and the use are directly influenced.

The invention aims to achieve the purpose and the effect of a demagnetization and fine grinding integrated structure of a rocker arm shaft, and is achieved by the following specific technical means:

a rocker arm shaft demagnetization and fine grinding integrated structure comprises a track motor, a main driving wheel, a feeding hopper, a centerless grinding machine, a demagnetization machine and a supporting block; the track motor is screwed and fixed on one side of the top surface of the working table top through screws; the main driving wheel is fixedly connected to one end of a rotating rod of the track motor; the feed hopper is screwed and fixed on the top surface of the working table top through screws; the centerless grinding machine is screwed and fixed in the middle of the top surface of the worktable through screws; the track motor, the centerless grinding machine and the demagnetizer are electrically connected with an external power supply and a control switch; the supporting block is fixedly connected to one end of the top surface of the workbench surface, and the top of the supporting block is rotatably connected with an auxiliary driving wheel.

Furthermore, the outer parts of the main driving wheel and the auxiliary driving wheel are provided with two conveying belts, and the sections of the tracks of the conveying belts are circular.

Furthermore, top tracks of the external conveying belts of the main driving wheel and the auxiliary driving wheel sequentially pass through the centerless grinding machine and the demagnetizer in the conveying direction.

Furthermore, the feeder hopper is the slope design, and the bottom of feeder hopper is located the both sides of conveyer belt and is equipped with the track baffle.

Compared with the prior art, the invention has the following beneficial effects:

the device utilizes the mechanical structure that centerless grinder and demagnetization machine all have the conveyer belt, merges demagnetization machine and centerless grinder, shares a conveyer belt, gets rid of the demagnetization process that can produce the part and collide with after the correct grinding. The original generation of collision, selection and rework is changed into the generation of no collision, so that the problem of part scrapping caused by collision is fundamentally solved.

Firstly, the conveyer belt is equipped with two, and the track cross-section of conveyer belt is circular for when the work piece is polished by centerless grinder, the work piece can rotate and can both be polished smoothly in order to guarantee all surfaces of work piece, has improved the device's flexibility and practicality.

Secondly, the top track of conveyer belt passes centerless grinder and demagnetization machine in proper order on the direction of transfer and makes the work piece can at first carry out the operation of correct grinding excircle on the conveyer belt, then just can get into the demagnetization machine and carry out the demagnetization operation, and a conveyer belt of twice process sharing makes the phenomenon that the work piece can not appear colliding with, has improved the device's stability and practicality.

Moreover, the track baffle can prevent that the work piece from dropping out the conveyer belt and causing unnecessary part loss in transportation process, has improved the device's stability and adaptability.
