Description

Technical Field

[0001] This utility model relates to the field of plasma polishing technology, specifically to a plasma polishing machine with a flipping mechanism. Background Technology

[0002] Plasma polishing is an environmentally friendly polishing process. Under high temperature and pressure, charged ions are formed through the action of the anode and cathode, forming a dense oxide film on the surface of the part, removing burrs from the part and polishing the surface of the part to a smoother finish.

[0003] Existing plasma polishing machines typically use hangers to fix various components, then immerse them in polishing liquid and apply electricity. During this process, since the polishing effect is directly related to the depth of the workpiece immersed in the polishing tank, the polishing equipment will add a flipping structure to ensure that the hanger is flipped vertically during the polishing process, so as to ensure that the polishing effect of products in the same batch is consistent.

[0004] However, in the above structure, the fixture usually carries a lot of metal workpieces. Therefore, after a single polishing is completed, it takes a long time to pick up and put down these metal parts, and then to fix new workpieces. During the whole process, the polishing equipment is in a stopped state, which affects the production efficiency of the entire polishing equipment. Utility Model Content

[0005] Based on the above description, this utility model provides a plasma polishing machine with a flipping mechanism to solve the problem that existing polishing equipment requires a long time to replace parts after a single polishing operation in order to carry out a second polishing operation. During this period, the entire polishing equipment is in a shutdown state, which leads to a reduction in the production efficiency of the entire polishing equipment.

[0006] This utility model is achieved through the following technical solution:

[0007] A plasma polishing machine with a flipping mechanism includes a base, a hydraulic cylinder at the top of the base, a connecting seat at the top of the hydraulic cylinder, a conveying assembly movably mounted on the outer side wall of the connecting seat, a mounting plate extending horizontally in all four directions from the side wall of the conveying assembly, a flipping frame at the lower end of the mounting plate, a hanger at the bottom of the flipping frame, and installation stations and polishing tanks spaced apart around the base. The conveying assembly sequentially conveys the hanger to the installation stations and polishing tanks by rotating.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Further, the conveying component includes a sleeve, which is movably sleeved on the connecting seat through a ball bearing, and the mounting plate is arranged in a cross-shaped structure and fixedly connected to the side of the sleeve. Moreover, a toothed structure is provided on the bottom surface of the sleeve, and a driving motor is provided on the connecting seat and is in transmission connection with the toothed part.

[0010] Further, a connecting part is provided on the bottom surface of the end of the mounting plate. A circular through hole is provided at the center of the bottom surface of the connecting part. A protruding part is provided on the top of the turning frame and is inserted into the circular through hole.

[0011] Further, the connecting part is arranged in a cylindrical shape and has flanges on the four sides of the bottom surface. The flanges are locked and fixed to the top surface of the turning frame through bolts.

[0012] Further, the turning frame is arranged in an inverted U-shaped structure. A movable seat is provided on the inner side wall of the bottom end of the vertical section of the turning frame. The hanger is located between the two movable seats, and both ends of the central axis extend outward and are inserted into the movable seats.

[0013] Further, a conductive rod is provided inside the hanger. A number of insertion rods for hanging workpieces are arranged around the outer side wall of the hanger. The insertion rods extend inward and are connected to the surface of the conductive rod. One end of the conductive rod is provided with a rotary connector. Both the turning frame and the central axis are arranged to be hollow and communicate with each other. The end of the rotary connector is connected and passes through the turning frame through a wire and forms an interface on the surface of the connecting part.

[0014] Further, a power supply is provided at the top end of the hydraulic cylinder. The positive pole of the power supply extends along the surface of the mounting plate through a wire and is connected to the interface. The negative pole of the power supply is directly connected to the inside of the polishing pool through a wire.

[0015] Further, a servo motor is also provided inside the vertical section of the turning frame on the side far from the rotary connector. The output end of the servo motor is in transmission connection with the end of the central axis.

[0016] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0017] The present application is improved based on the existing plasma polishing machine. By using the method of rotary conveying and cooperating with multiple hangers, it continuously inputs them into the polishing pool.

[0025] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0027] Combination Figure 1-6 As shown, a plasma polishing machine with a flipping mechanism includes:

[0028] The base 1 is the conveying part of the entire polishing equipment. A hydraulic cylinder 11 is vertically installed on its top. A connecting seat 12 is provided at the top of the output end of the hydraulic cylinder 11. Installation stations and polishing pools are arranged in sequence around the base 1 at intervals.

[0029] The conveying component 2 is movably mounted on the connecting seat 12 and can rotate flexibly;

[0030] The flipping frame 3 is located at the bottom of the conveying assembly 2 and is used to flip the components vertically to ensure consistent polishing quality.

[0031] The fixture 4 is arranged at the bottom of the turnover frame 3, and the processed parts are hung on the side wall surface.

[0032] Specifically; in this embodiment, the conveying component 2 includes a cross-shaped plate structure composed of 4 mounting plates 21, and a sleeve 22 located at the center of the structure. The two are fixedly connected, and the sleeve 22 is directly sleeved on the connecting seat 12 and is movably assembled by using a ball bearing. The bottom of the sleeve 22 protrudes downward and has a toothed portion on the inner ring surface. A driving motor 23 is correspondingly arranged on the connecting seat 12. A gear is arranged on the output end of the driving motor 23 and is in transmission engagement with the toothed portion, so as to drive the entire conveying component 2 to rotate, so as to cooperate with the polishing equipment for continuous conveying.

[0033] Moreover, a connecting portion 24 is further arranged on the bottom surface of the mounting plate 21 at the end far from the hydraulic cylinder 11. The connecting portion 24 is integrally arranged in a cylindrical shape, and a circular through hole is arranged at the center of the bottom surface. A cylindrical protruding portion 31 is correspondingly arranged at the top end of the turnover frame 3, and the protruding portion 31 is exactly inserted into the circular through hole. Flanges are further arranged on the four sides of the bottom surface of the connecting portion 24. Bolt holes are arranged on the flanges and are locked and fixed to the top surface of the turnover frame 3 by using bolts.

[0034] The turnover frame 3 is arranged in a "冂" - shaped structure, and a movable seat 32 is arranged on one side of the two vertical segments opposite to each other. The movable seat 32 is arranged by using a ball bearing structure and has a hole at the center. The fixture 4 is exactly horizontally arranged between the two vertical segments, and both ends of the central axis 41 of the fixture 4 are respectively inserted into the holes of the two movable seats 32, and the movable seat 32 also seals the connection part by using a sealing ring.

[0035] The fixture 4 is integrally arranged in a rectangular shape. The central axis 41 is hollow inside and is communicated with the inside of the fixture 4. Moreover, a conductive rod 42 is further arranged at the center of the fixture 4. A plurality of insertion rods 43 made of metal material are vertically arranged on the outer side wall of the fixture 4. The insertion rods 43 are connected and fixed to the metal workpiece, and their ends extend inward and are fixedly connected to the side wall of the conductive rod 42.

[0036] One end of the conductive rod 42 is further provided with a rotary connector. The rotary connector can adopt the circuit rotary connector of AsianTool or other models of connectors. A wire is arranged at the other end of the rotary connector. On this basis, the central axes 41 at both ends of the fixture 4 and the inside of the turnover frame 3 are both hollow, and a through hole is opened on the top surface of the protruding portion 31 at the top of the turnover frame 3. The wire extends along the central axis 41 and the inner wall of the turnover frame 3 to the inside of the connecting portion 24, and an interface 25 is formed on the side wall of the connecting portion 24.

[0037] Additionally, a power supply 5 is located at the top of the rectangular base. This power supply 5 is equipped with a PLC controller and a rotary connector at its top. The rotary connector at this location has four connection ports, each equipped with a control switch. The four control ports extend along the surface of the mounting plate 21 to the connection part 24 via wires and are electrically connected to the interface 25. The four control ports are controlled by the PLC controller so that the hanger 4 located at the installation station is disconnected from the power supply 5, while the hanger 4 located at the polishing tank is connected to the power supply 5. The negative terminal of the power supply 5 is directly connected to the inside of the polishing tank via a wire. Therefore, whenever the power supply 5 is connected, the hanger 4 located in the polishing tank can be energized, and the surface treatment of the workpiece can be accelerated by electrolysis.

[0038] In the vertical section of the flipping frame 3, a servo motor 33 should be installed on the side away from the rotary connector. This servo motor 33 is connected to the central shaft 41 at the other end, thereby driving the entire hanger 4 to rotate vertically without affecting the power supply of the hanger 4. Furthermore, the servo motor 33's wiring can also be powered through the aforementioned power supply structure, so that the servo motor 33 and the electrolytic polishing process operate synchronously whenever the corresponding control switch is turned on. For example... Figure 5 As shown, area A is the installation station and area B is the polishing pool. Each time it runs, the tools on the two hangers 4 can be polished simultaneously, which greatly improves the polishing efficiency.

[0039] Combining the above-mentioned conveying method, this embodiment can achieve continuous and uninterrupted conveying of the hanger 4 through the lifting operation of the hydraulic cylinder 11 and the on / off control of the circuit by the PLC, thereby ensuring that there are always tools in the polishing pool for polishing operations, which greatly improves the production efficiency of the entire polishing equipment. At the same time, the rotation process will not affect the circuit, making it convenient to use.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
