Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, a plastic part surface polishing device includes a processing table 1; a support frame 2 is fixedly connected to the top of the processing table 1; a polishing component 3 is installed at the bottom of the support frame 2; a pair of telescopic slides 4 are fixedly connected to the top of the processing table 1; the pair of telescopic slides 4 are symmetrically arranged on the processing table 1; a slider 5 is slidably connected to the middle of the telescopic slides 4; a drive motor 6 is fixedly connected to the side wall of one of the sliders 5; a first fixing rod 7 is fixedly connected to the output end of the drive motor 6; the first fixing rod 7 passes through the side wall of the slider 5; a second fixing rod 8 is rotatably connected to the side wall of the other slider 5. During operation, by providing a pair of telescopic slides 4 on the processing table 1, when it is necessary to polish the surface of the plastic part, the plastic part is placed between the pair of telescopic slides 4, and then the control switch is used to control the pair of sliders 5 to slide on the telescopic slides 4 and move closer to each other, thereby driving the first fixing rod 8. Rod 7 and the second fixing rod 8 move closer together. At this time, the first fixing rod 7 and the second fixing rod 8, which are close to each other, will clamp and fix the plastic part located in the middle position. Then, the control switch of the grinding assembly 3 is turned on, so that the grinding assembly 3 descends and performs grinding operation on the surface of the plastic part. During the grinding process, the switch of the drive motor 6 can be controlled to drive the first fixing rod 7 to rotate, thereby causing the plastic part fixed by the first fixing rod 7 and the second fixing rod 8 to rotate and grind different surfaces of the plastic part. The position of a pair of sliders 5 on the telescopic slide table 4 can also be controlled to move the clamped and fixed plastic part laterally, thereby changing the position of the plastic part and grinding different parts of the plastic part. When plastic parts of different lengths can be fixed and ground without changing the clamps, the processing range and adaptability of the plastic parts can be increased, making the grinding process of plastic parts more convenient and faster.

[0025] like Figures 1 to 5As shown, a fixing plate 9 is fixedly connected to the ends of the first fixing rod 7 and the second fixing rod 8; a plurality of positioning rods 10 are slidably connected to the side wall of the fixing plate 9; the positioning rods 10 are evenly distributed on the fixing plate 9; a compression spring 11 is fixedly connected to the end of the positioning rod 10; the end of the compression spring 11 is fixedly connected to the inner side wall of the fixing plate 9. During operation, a fixing plate 9 is provided at the ends of the first fixing rod 7 and the second fixing rod 8. When the first fixing rod 7 and the second fixing rod 8 clamp the plastic part under the push of the drive motor 6, the fixing plate 9 located at the ends of the first fixing rod 7 and the second fixing rod 8 will contact the surface of the plastic part. At this time, the plastic part will squeeze the positioning rods 10 on the surface of the fixing plate 9, causing the positioning rods 10 on the contact surface of the plastic part to slide into the fixing plate 9. At this time, the positioning rods 10 that are not in contact with the surface of the plastic part will remain in the external state and will surround the plastic part, forming a limiting effect on the plastic part. During the rotation of the plastic part, further limiting and fixing of the plastic part can be achieved, improving the stability of the plastic part during processing and polishing.

[0026] like Figures 2 to 3 As shown, the processing table 1 has multiple through holes 13 in the middle; the through holes 13 are located below the grinding assembly 3; a collection box 14 is fixed to the bottom side wall of the processing table 1; the collection box 14 is located below the through holes 13. During operation, when grinding the surface of the plastic part, plastic debris is generated. This debris is prone to accumulation on the surface of the processing table 1, which hinders subsequent processing and grinding. At this time, by providing through holes 13 on the processing table 1, the debris generated during grinding can fall into the collection box 14 below through the through holes 13, and the debris can be collected uniformly and cleaned up.

[0027] like Figure 3 As shown, the collection box 14 has a hinged door 15 on its side wall; a latch 16 is hinged to the end of the door 15; and a lock body 17 is fixed to the side wall of the collection box 14. The latch 16 and the lock body 17 are configured to work together. During operation, the door 15 on the collection box 14 can be opened and closed, which can reduce the pollution caused by debris scattering. The latch 16 and the lock body 17 also make the opening and closing of the door 15 more convenient and quick.

[0028] like Figures 1 to 2 As shown, a dust cover 18 is fixedly connected to the top of the processing table 1; the dust cover 18 is sleeved on the telescopic slide table 4; a cover door 19 is hinged to the side wall of the dust cover 18. During operation, by providing a dust cover 18 on the processing table 1, the cover door 19 can be opened to place and install plastic parts, and then the cover door 19 can be closed during operation to achieve the airtightness of the working environment, thereby reducing the impact of dust and other impurities generated during grinding on the working environment.

[0029] like Figure 1As shown, an observation window 20 is fixed to the side wall of the dust cover 18; the observation window 20 is made of transparent material. During operation, the observation window 20 allows the staff to observe the polishing process at any time, making it easier to deal with emergencies and protecting the safety of the staff while making the polishing work safer.

[0030] Working principle: A pair of telescopic slides 4 are provided on the processing table 1. When surface polishing of a plastic part is required, the plastic part is placed between the pair of telescopic slides 4. Then, by controlling the switch, a pair of sliders 5 are controlled to slide on the telescopic slides 4 and move closer to each other, thereby driving the first fixing rod 7 and the second fixing rod 8 to move towards the middle. At this time, the first fixing rod 7 and the second fixing rod 8, which are close to each other, will clamp and fix the plastic part located in the middle position. Then, the control switch of the polishing assembly 3 is turned on, causing the polishing assembly 3 to descend and perform polishing operation on the surface of the plastic part. During the polishing process, the control can be adjusted. The switch of the drive motor 6 is turned on, causing the drive motor 6 to rotate the first fixed rod 7, which in turn causes the plastic part fixed by the first fixed rod 7 and the second fixed rod 8 to rotate, grinding different surfaces of the plastic part. It can also control the position of a pair of sliders 5 on the telescopic slide table 4, causing the clamped plastic part to move laterally, thereby changing the position of the plastic part and grinding different parts of the plastic part. When plastic parts of different lengths can be fixed and ground without changing the fixture, the processing range of plastic parts and the adaptability of the device can be increased, making the grinding process of plastic parts more convenient and faster.

[0031] Fixing discs 9 are provided at the ends of the first fixing rod 7 and the second fixing rod 8. When the first fixing rod 7 and the second fixing rod 8 clamp the plastic part under the push of the drive motor 6, the fixing discs 9 located at the ends of the first fixing rod 7 and the second fixing rod 8 will contact the surface of the plastic part. At this time, the plastic part will squeeze the positioning rods 10 on the surface of the fixing disc 9, causing the positioning rods 10 on the contact surface of the plastic part to slide into the fixing disc 9. At this time, the positioning rods 10 that are not in contact with the surface of the plastic part will remain in the external state and will surround the plastic part, forming a limiting effect on the plastic part. During the rotation of the plastic part, further limiting and fixing of the plastic part can be achieved, improving the stability of the plastic part during processing and polishing.

[0032] When polishing the surface of plastic parts, plastic debris is generated. This debris tends to accumulate on the surface of the processing table 1, which can hinder subsequent polishing. By providing a through hole 13 on the processing table 1, the debris generated during polishing can fall into the collection box 14 below, allowing for unified collection and easy cleaning.

[0033] By providing an openable door 15 on the collection box 14, the problem of debris scattering and causing environmental pollution can be reduced. The cooperation of the latch 16 and the lock body 17 also makes the opening and closing of the door 15 more convenient and quick.

[0034] By providing a dust cover 18 on the processing table 1, the cover door 19 can be opened during operation to place and install plastic parts, and then the cover door 19 can be closed during operation to achieve a sealed working environment, thereby reducing the impact of dust and other impurities generated during grinding on the working environment.

[0035] By setting up the observation window 20, staff can observe the polishing process at any time, making it easier to deal with emergencies and ensuring the safety of staff while making the polishing work safer.
