Description

Technical Field

[0001] The invention relates to the technical field of workpiece polishing, and more particularly to a polishing device with switchable polishing tools. Background Art

[0002] Polishing milling machine is a machine tool equipment that combines polishing and milling functions. It can not only polish the workpiece, but also perform milling. It has a wide range of applications and high efficiency. The working principle of polishing milling machine is based on the combination of milling and polishing. The milling cutter mainly moves in rotation, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, curved surfaces, etc. The polishing unit improves the surface quality and precision of the workpiece by polishing the surface of the workpiece. Due to the characteristics of multi-edge intermittent cutting, the productivity of the milling machine is high and it is suitable for large-scale production.

[0003] The existing patent is a multi-axis milling machine for polishing processing. The patent authorization number CN216657532U includes a base, an electric control telescopic rod 1, an electric control telescopic rod 2, an electric control telescopic rod 3, a motor and a controller. The upper end of the base is fixedly connected to one end of a support column, and the other end of the support column is fixedly connected to the bottom end of the operating table. A limiting plate is fixedly connected to the middle of the upper end of the operating table, and the limiting plate is placed on the product to be processed. The right side of the upper end of the base is fixedly connected to one end of a support plate, and the other end of the support plate is fixedly connected to the bottom end of the support plate. The present invention utilizes the principle of multi-axis operation of machine tools and multi-angle swing processing. The feed amount can be digitally controlled, which can greatly improve the product accuracy and surface finish of the product, shorten the processing time, and save labor. After the grinding wheel is modified, due to surface cutting, the overall processing accuracy and finish of the product are improved, and no knife marks will be produced. Compared with the manual processing process, the machine tool grinding process has good efficiency and high stability.

[0004] However, the polishing tool head in patent authorization number CN216657532U is a single tool head structure. Different types of tools need to be frequently replaced on the milling machine to adapt to different processing needs. Tool changing on the milling machine is the process of replacing tools. Its main purpose is to replace tools in order to change the shape and size of the workpiece. Frequent replacement not only increases the labor intensity of manual labor, but also reduces the efficiency of workpiece processing. Therefore, we propose a polishing device with switchable polishing tools to solve the above-mentioned problems. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a polishing device with switchable polishing tools, which can arbitrarily switch the tool heads, eliminating the operation of frequent manual replacement of tool heads, reducing manual labor intensity, and improving the efficiency of workpiece processing.

[0007] 2. Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A polishing device with switchable polishing tools comprises a machine tool, a slide rail symmetrically mounted on the top of the machine tool, a slide seat slidably connected to the slide rail, a telescopic cylinder mounted between the slide rails and having a movable end connected to the slide seat, a drive motor mounted on the upper surface of the slide seat, and a fixture mounted on the power output end of the drive motor, a connecting frame mounted above the fixture, a vertical plate fixedly connected to the upper surface of the connecting frame, and two vertical plates are transversely arranged, a rotating shaft is rotatably connected between the vertical plates through bearings, and a reduction motor with a power output end drivingly connected to the rotating shaft is mounted on the surface of one of the vertical plates;

[0010] An eccentric wheel is installed on the outer wall of the rotating shaft, and two eccentric wheels are provided, and the two eccentric wheels are arranged in opposite directions;

[0011] A knife sleeve fixedly connected to the connecting frame is arranged below the eccentric wheel, a cavity is opened on the inner side of the knife sleeve, a knife handle longitudinally penetrating the knife sleeve is arranged in the cavity, a limit plate is fixedly connected to the outer wall of the knife handle located on the inner side of the cavity, springs are symmetrically installed below the limit plate, and a knife head is connected to the bottom end of the knife handle by a screw.

[0012] Furthermore, a guide sleeve is symmetrically fixedly connected to an edge of the machine tool away from the telescopic cylinder, a telescopic rod is movably connected to the top of the guide sleeve, and the top of the telescopic rod is welded to the connecting frame.

[0013] Furthermore, the telescopic rod and the outer wall of the guide sleeve are both fixedly connected with connecting seats, and an electric push rod is installed between the connecting seats.

[0018] Furthermore, the fixture clamps a workpiece with a cylindrical structure, and the workpiece corresponds to the tool head.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) In this scheme, the clamp is driven by a driving motor to rotate, thereby cutting and polishing the workpiece. When the cutter head needs to be replaced, the reduction motor drives the rotating shaft to rotate in conjunction with the vertical plate to exchange the position of the eccentric wheel. One of the tool handles is separated from the contact with the eccentric wheel and reset upward by a spring and a limit plate, while the top of the other tool handle contacts the eccentric end of the eccentric wheel, pressing the tool handle downward so that the workpiece can be polished with the replaced tool head. This eliminates the need for frequent manual replacement of tool heads, reduces labor intensity, and improves workpiece processing efficiency.

[0022] (2) This solution utilizes the movable end of the electric push rod to push the telescopic rod to move up and down in conjunction with the guide sleeve, so that the position of the cutter head can be adjusted according to the diameter of the workpiece. Therefore, workpieces of different sizes can be processed, thereby improving applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] An eccentric wheel 11 is installed on the outer wall of the rotating shaft 9. Two eccentric wheels 11 are provided, and the two eccentric wheels 11 are arranged in opposite directions.

[0035] A knife sleeve 12 fixedly connected to the connecting frame 7 is arranged below the eccentric wheel 11, a cavity 13 is opened inside the knife sleeve 12, a knife handle 14 longitudinally penetrating the knife sleeve 12 is arranged at the cavity 13, a limit plate 15 is fixedly connected to the outer wall of the knife handle 14 located inside the cavity 13, a spring 16 is symmetrically installed below the limit plate 15, and a knife head 17 is connected to the bottom end of the knife handle 14 by screws;

[0036] It should be noted that when the polishing device of the switchable polishing tool is in use, the workpiece 21 is clamped in the fixture 6, and then the height of the cutter head 17 is adjusted so that it abuts against the side wall of the workpiece 21. The fixture 6 is driven to rotate by the driving motor 5, so that the workpiece 21 is cut and polished.
