Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, and in particular to a mechanical parts polishing device. Background Technology

[0002] For example, patent application CN202223212043.5 discloses a polishing device for mechanical parts, including a bed frame. An assembly opening is located in the middle of one side of the top surface of the bed frame. A movable frame is slidably connected inside the assembly opening. A motor is installed on the outer side of the movable frame, and a turntable is installed at the output end of the motor. A grinding wheel is installed in front of the turntable. This polishing device uses the bed frame as its main body, with an assembly opening in the middle of one side of the top surface of the bed frame. The movable frame is L-shaped and located inside the assembly opening. A turntable, driven by a motor, is installed outside the movable frame. A grinding wheel is installed in front of the turntable. Simultaneously, a second assembly groove is formed recessed on the outer side of the turntable, and a grinding belt is installed inside the second assembly groove. In use, the workpiece is placed on the bed frame, and the flat and curved surfaces of the workpiece can be polished by the grinding wheel and grinding belt, respectively.

[0003] However, the polishing process for mechanical parts requires high surface treatment precision and processing efficiency. Traditional polishing equipment often uses manual clamping to fix the workpiece (such as the mechanical clamping of the workpiece by driving the clamping plate with a threaded rod in the above scheme), which has problems such as uneven clamping force leading to deformation of parts and damage to thin-walled parts. At the same time, when polishing parts in the comparative document, it is necessary to frequently adjust the position of the workpiece or change tools, which is time-consuming and cumbersome. In addition, the workpiece in the comparative document is fixed on the top surface of the bed frame, resulting in poor adaptability to parts of different sizes. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A mechanical parts polishing device includes an operating table 1. Each of the four corners of the bottom of the operating table 1 is provided with a support leg 101. Adjacent support legs 101 are connected by connecting legs 102 to form a frame structure. The frame structure formed by the support legs 101 and the connecting legs 102 enhances the overall stability of the device and avoids polishing vibration from affecting the accuracy.

[0025] Furthermore, in the embodiments of this disclosure, the top of the operating table 1 is fixed with a base 2, and the top of the base 2 is provided with a moving component 3. The moving component 3 includes a slide groove 301 formed on the surface of the base 2. A lead screw 302 is transversely arranged in the slide groove 301. The lead screw 302 is rotatably connected to the inner wall of the slide groove 301 through a bearing. A slider 303 is threadedly fitted on the lead screw 302.

[0026] Furthermore, a first drive motor 304 is fixed on one side of the base 2, and the output end of the first drive motor 304 is connected to one end of the lead screw 302 via a coupling; the top of the slider 303 is vertically connected to the fixed base 4, and a hydraulic cylinder 402 is provided on the back of the fixed block 401. The output end of the hydraulic cylinder 402 passes through the fixed block 401 and is connected to the grinding motor 5. A polishing disc 501 is installed on the output end of the grinding motor 5.

[0027] In addition, in this embodiment of the utility model, the bottom of the operating table 1 is provided with a drive box 6, and an electric push rod 7 is vertically installed in the drive box 6. The top of the electric push rod 7 passes through the operating table 1 and is connected to the parts placement tray 8. The height of the parts placement tray 8 can be adjusted by raising and lowering the electric push rod 7. The electric push rod 7 can quickly adapt to the polishing requirements of parts of different heights by vertically raising and lowering.

[0028] Example 2

[0029] Please continue to refer to Figures 1-4 Unlike Embodiment 1, in this embodiment of the present invention, the electric push rod 7 and the drive box 6 are rotatably connected by bearings. The electric push rod 7 is surrounded by a driven gear 601 and located inside the drive box 6. The driven gear 601 meshes with the driving gear 602. The bottom of the drive box 6 is fixed with a second drive motor 603. The output end of the second drive motor 603 is connected to the driving gear 602 for transmission, so as to realize the overall rotation of the electric push rod 7. An electromagnet 801 is embedded on the top surface of the parts placement tray 8 for adsorbing and fixing metal parts.

[0030] In addition, in this embodiment of the utility model, a control panel 9 is provided on the other side of the front of the operating table 1. The control panel 9 is electrically connected to the first drive motor 304, the hydraulic cylinder 402, the grinding motor 5, the electric push rod 7, the second drive motor 603 and the electromagnet 801.

[0031] When using a mechanical parts polishing device, before operation, the parts to be polished are placed on the top surface of the parts placement tray 8 and fixed by electromagnet 801 being energized; then, by the operation of the electric push rod 7 in the drive box 6, its output end pushes the placement tray to rise, and the height of the placement tray is adjusted accordingly according to the height of the parts in order to carry out subsequent polishing.

[0032] After the part is positioned, the hydraulic cylinder 402 pushes the grinding motor 5 forward, so that the polishing disc 501 contacts the surface of the part. The grinding motor 5 drives the polishing disc 501 to rotate at high speed to perform the polishing operation. With the cooperation of the moving component 3, the operator starts the first drive motor 304 through the control panel 9 to drive the lead screw 302 to rotate, so that the slider 303 drives the fixed seat 4 to move laterally. While adjusting the horizontal position of the polishing disc 501, one side of the part is also polished.

[0033] After one side of the part is processed, the hydraulic cylinder 402 drives the grinding motor 5 to move backward, and the polishing disc 501 does not contact the part. Then, the second drive motor 603 drives the driven gear 601 to rotate through the drive gear 602, causing the electric push rod 7 to rotate as a whole, driving the part to rotate synchronously, and then polishing the other unprocessed side of the part.

[0034] During the polishing process, the part placement disk 8 rotates continuously to achieve uniform polishing at multiple angles. The moving component 3 adjusts the lateral position of the polishing disk 501 in real time. The hydraulic cylinder 402 finely adjusts the contact depth of the polishing disk 501 according to the polishing pressure requirements. After polishing is completed, each driving component resets, and the electromagnet 801 is de-energized to release the part.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
