TECHNICAL FIELD

[0001] The application relates to the technical field of polishing devices, in particular to a polishing device for mold machining. BACKGROUND

[0002] In the mold machining process, polishing is an important process, and the machining quality directly affects important performance indicators such as the precision, surface finish and service life of the mold. In the mold machining process, polishing refers to the process operation of using various polishing tools and abrasives to process the surface of the mold to improve its appearance, precision, surface quality and physical properties.

[0003] For the above related technology, the inventors believe that the mold polishing operation in the traditional technology is usually manually operated by a polishing tool. This method has many drawbacks. On the one hand, manual polishing cannot guarantee the consistency and uniformity of polishing. Different operators may have different polishing effects due to differences in skill level, experience and physical strength, thereby affecting the final quality of the mold. In addition, the workpiece is difficult to rotate at multiple angles, so it is difficult to polish various shaped polishing pieces. Therefore, in order to solve the above problems, the application provides a polishing device for mold machining. CONTENT OF THE UTILITY MODEL

The surface of the fixing seat is fixedly connected with a servo motor. The output end of the servo motor is fixedly connected with a driving gear. The outer part of the driving gear is engaged with a driven gear. The inner part of the driven gear is fixedly connected with a rotating shaft. The top of the rotating shaft is fixedly connected with a machining disc. The surface of the fixing seat is fixedly installed with a U-shaped plate through a connecting plate. The outer side wall of one wing of the U-shaped plate is fixedly connected with a driving motor. The output end of the driving motor is fixedly connected with a threaded rod through a shaft coupling. The outer part of the threaded rod is threadedly connected with an adjusting seat.

[0006] Preferably, the clamping assembly comprises a horizontal groove opened on the surface of the machining disc. One end of the horizontal groove is fixedly connected with a forward and reverse motor. The output end of the forward and reverse motor is fixedly connected with a bidirectional screw rod through a shaft coupling. The outer part of the bidirectional screw rod is symmetrically threadedly connected with two adjusting blocks. The top of each adjusting block is fixedly connected with a clamping plate.

[0007] Preferably, the polishing assembly comprises a cylinder fixedly connected to the bottom of the adjusting seat, the output end of the cylinder is fixedly connected with a transverse plate, the bottom of the transverse plate is fixedly connected with a vertical plate, the bottom of the vertical plate is hingedly connected with a movable plate, the bottom of the movable plate is provided with a polisher, and the bottom of the transverse plate is hingedly connected with an electric telescopic rod, and the output end of the electric telescopic rod is hingedly connected with the inner side wall of the movable plate.

[0008] Preferably, the bottom end of the rotating shaft is rotatably connected to the surface of the fixed seat through a bearing.

[0009] Preferably, the opposite sides of the two clamping plates are provided with a plurality of rows of arc-shaped protrusions.

[0010] In summary, the present application has the following beneficial technical effects:

[0011] 1. By arranging the cylinder, electric telescopic rod and hinge in the polishing assembly, the position and angle of the polisher can be accurately controlled.

[0022] With reference to Figure 3 And Figure 5 , the clamping assembly includes a horizontal groove 11 opened on the surface of the machining disc 7, one end of the horizontal groove 11 is fixedly connected with a reversible motor 12, the output end of the reversible motor 12 is fixedly connected with a bidirectional screw rod 13 through a shaft coupling, the outside of the bidirectional screw rod 13 is symmetrically screwed with two adjusting blocks 14, the top of each of the two adjusting blocks 14 is fixedly connected with a clamping plate 15, when the reversible motor 12 is started, the bidirectional screw rod 13 will rotate, the outside of the bidirectional screw rod 13 is symmetrically screwed with the two adjusting blocks 14, according to the transmission principle of the bidirectional screw rod 13, when the bidirectional screw rod 13 rotates, due to the characteristics of its threads, the two adjusting blocks 14 will move towards or away from each other in the horizontal groove 11, the top of the adjusting block 14 is fixedly connected with the clamping plate 15, therefore, when the adjusting block 14 moves, the clamping plate 15 will move synchronously, the bottom of the clamping plate 15 is tightly attached to the surface of the machining disc 7, achieving the clamping or loosening operation of the mold placed on the machining disc 7.
