DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4 As shown, a plastic part polishing device includes a workbench 1, a support plate 2 and support legs 3. The support plate 2 is provided on the outer wall of the bottom end of the front side of the workbench 1, and the bottoms of the workbench 1 and the support plate 2 are both installed with support legs 3. A polishing control mechanism 4 is provided on the top rear side of the workbench 1, a resistance limit mechanism 5 is provided in the middle of the top of the workbench 1, and a debris collection mechanism 6 is provided on the top of the support plate 2.

[0025] The polishing control mechanism 4 includes a support seat 41, a servo motor 42, a mounting plate 43 and a polishing plate 44. The support seat 41 is arranged just above the middle of the top of the workbench 1. The top of the support seat 41 is provided with a servo motor 42. The output end of the servo motor 42 rotates through the support seat 41 and is fixedly connected to the mounting plate 43. The bottom of the mounting plate 43 is fixedly provided with a polishing plate 44. A support box 45 is provided on the top rear side of the workbench 1. A reciprocating screw rod 47 is provided for rotation inside the support box 45. A drive motor 46 is provided on the top outer wall of the support box 45. The output end of the drive motor 46 rotates through the support seat 41 and is fixedly connected to the mounting plate 43. The polishing plate 44 is fixedly provided at the bottom of the mounting plate 43. After extending to the interior of the support box 45, it is fixedly connected to the top of the reciprocating screw 47. The bottom end of the reciprocating screw 47 is rotatably installed with the bottom inner wall of the support box 45. A limit bar 48 is arranged at intervals on one side of the reciprocating screw 47. The top and bottom ends of the limit bar 48 are respectively connected to the top inner wall and the bottom inner wall of the support box 45. A limit block 49 is provided for sliding inside the support box 45. The reciprocating screw 47 is threaded through the limit block 49. The limit bar 48 slides through the limit block 49. The limit block 49 is set to a horizontal "convex" shape, and the protruding end of the limit block 49 is connected to the side of the support seat 41.

[0026] When it is necessary to polish the plastic part after it has been positioned, it is first necessary to turn on the drive motor 46. After the drive motor 46 is turned on, it will drive the reciprocating screw 47 to rotate, and then drive the limit block 49 to move. Here, due to the setting of the limit bar 48, the reciprocating screw 47 will only drive the limit block 49 to realize the sliding trajectory movement in the vertical direction when it rotates, and then the movement of the limit block 49 will drive the support seat 41 to move, and then the movement of the support seat 41 will automatically drive the polishing disc 44 to move; when the polishing disc 44 moves to a suitable polishing height, the drive motor 46 is turned off at this time. It should be noted that the drive motor 46 has a self-locking function. After it is turned off, the polishing disc 44 can still maintain its position after movement; then the servo motor 42 is turned on. When the servo motor 42 is turned on, it will drive the mounting disc 43 to rotate, and then drive the polishing disc 44 to rotate. When the polishing disc 44 rotates, it will polish the plastic part clamped by the conflict limit mechanism 5.

[0027] In the embodiment, the interference limiting mechanism 5 includes a placement groove 51, a driving cylinder 52 and a support plate 53. A placement groove 51 is provided inside the workbench 1. Two driving cylinders 52 are symmetrically provided inside the placement groove 51. The output ends of the two driving cylinders 52 are fixed with support plates 53. The bottom surface of the support plate 53 is slidably installed with the inner bottom wall of the placement groove 51. The top of the two support plates 53 is provided with mounting blocks. Two avoidance grooves connected to the placement groove 51 are provided in the middle of the top of the workbench 1. The tops of the two mounting blocks slide through the two avoidance grooves and are fixedly connected to the support back plate 54. The bottom surface of the support back plate 54 is slidably installed with the top surface of the workbench 1. The sides of the two support back plates 54 that are close to each other are provided with friction pads 55. The polishing disc 44 is located directly above the two support back plates 54, so that after the two support back plates 54 clamp and fix the plastic parts, the polishing disc 44 can easily polish the plastic parts.

[0028] When the plastic part to be polished needs to be positioned, the plastic part must first be adjusted to a suitable position and placed in the middle of the workbench 1 with the polished surface facing upwards. The two driving cylinders 52 are then started synchronously. When the driving cylinders 52 are turned on, the two support plates 53 are driven to move toward each other, and the mounting blocks are driven to move toward each other. The two mounting blocks then move toward each other, which in turn drives the opposing support back plates 54 to move toward each other, and the two friction pads 55 are driven to move. As the two friction pads 55 move toward each other, the plastic part is clamped in the middle of the two friction pads 55, thereby completing the centering effect of the plastic part.

[0029] The debris collection mechanism 6 includes a storage box 61, a collection box 62 and an isolation filter plate 63. The storage box 61 is provided at the middle of the top of the support plate 2. The top outer wall of the storage box 61 is set as an opening structure, and the top of the storage box 61 is provided with a collection box 62. The lower end of the collection box 62 is connected to the top opening of the storage box 61, and the side of the collection box 62 close to the workbench 1 is an open structure. The top of the collection box 62 is provided with a through groove, and the isolation filter plate 63 is slidably installed inside the through groove; A limit handle 64 is provided at the top of the filter plate 63, and interference strips 65 are symmetrically provided on the outer walls of both sides of the isolation filter plate 63. The collection box 62 has corresponding interference slots on the inner walls on both sides of the through slot, and the interference strips 65 and the interference slots are snap-fitted together; an axial flow fan 66 is installed on the side of the collection box 62, and a through opening is provided on the side outer wall of the storage box 61, and a collection box 67 is slidably installed inside the storage box 61, and the collection box 67 slides with the through opening.

[0030] When debris is generated during the polishing process and needs to be cleaned, it is only necessary to turn on the axial flow fan 66. After the axial flow fan 66 is turned on, the debris on the workbench 1 will be sucked into the collection box 62 along with the air flow through negative pressure extraction. At this time, due to the setting of the isolation filter plate 63, the debris in the air flow will be isolated on the side of the isolation filter plate 63 and fall into the collection box 67 under the influence of gravity; when the isolation filter plate 63 has been used for a long time and needs to be cleaned, the limit handle 64 is directly pulled in the vertical upward direction, and the limit handle 64 is lifted upward to pull the isolation filter plate 63 out of the collection box 62; when reinstalling after cleaning, it is only necessary to adjust the isolation filter plate 63 to the appropriate position and push the interference card strip 65 on its side from top to bottom to the bottom of the interference card slot at the corresponding position to complete the installation.

[0031] When the utility model is in use, the plastic part is adjusted to a suitable position and placed in the middle position of the workbench 1 with the polishing surface facing upward. Then, the two driving cylinders 52 are started synchronously to drive the two supporting back plates 54 to move toward each other to clamp and fix the plastic part. The reciprocating screw rod 47 is driven by the motor 46 to drive the polishing disc 44 to move to a suitable height. Then, the servo motor 42 is started to drive the polishing disc 44 to rotate, thereby polishing the plastic part. By starting the axial flow fan 66, the debris on the workbench 1 is sucked into the inside of the collection box 62 along with the air flow, so that the debris falls into the inside of the collection box 67 and is collected and processed uniformly.

[0032] It is noted here that the above-mentioned servo motor 42, drive motor 46, drive cylinder 52 and axial fan 66 can be powered by existing conventional operating technical means, whether it is powered by a power supply component or an external wire. Since the grinding debris has directional uncertainty, a baffle can be set around the workbench 1 where the debris collection mechanism 6 is not set to isolate and block the debris, so that the above-mentioned debris collection mechanism 6 can better collect the debris. These are all existing conventional operating technical means and will not be described in detail here.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
