[0042] Please refer to Figure 1-2 , the present invention provides a technical solution: an automatic polishing device for a ticket vending machine sheet metal part, including:

[0043] Device housing 1, with a laterally penetrating processing station 2 arranged therein;

[0044] Adsorption seat 3, which is arranged at the bottom of the processing station 2, and several suction cups 4 are arranged thereon;

[0045] Several clamping seats 5, which are arranged at intervals along the circumferential direction of the adsorption seat 3 and are horizontally and laterally elastically slidably arranged on the outside of the adsorption seat 3, and clamping notches 6 are arranged on the inner side of the top thereof;

[0046] Lifting seat 7, which is sleeved on the outside of the clamping seat 5 and is vertically movably arranged in the processing station 2 through the first lifting drive device 8, and an inverted conical wedge-shaped ring surface is arranged on the inner side thereof, and the wedge-shaped ring surface is in sliding contact with the wedge-shaped surface on the outside of the clamping seat 5;

[0047] Polishing part 12, which is detachably arranged at the top of the processing station 2 through a drive mechanism, and polishes the sheet metal part.

[0048] Several connecting rods 51 are arranged on the inner side of the clamping seat 5, and the connecting rods 51 are correspondingly slidably inserted into the sockets 31 on the side of the adsorption seat 3, and elastic members 32 for elastically pre-tightening the connecting rods 51 outward are arranged in the sockets 31, so that the clamping seat 5 is tightened. When positioning the sheet metal part, the elastic pre-tightening effect of the elastic members 32 can be used to further improve the positioning strength of the sheet metal part, so as to avoid the offset of the sheet metal part during polishing.

[0049] The bottom of the clamping seat 5 is slidably connected to the sliding seat 33 on the outside of the adsorption seat 3. A guide rail is arranged on the sliding seat 33, and the guide groove at the bottom of the clamping seat 5 is slidably connected to the guide rail. The cross-sections of the guide rail and the guide groove are T-shaped. The above structure enables the clamping seat 5 to only move horizontally and radially with respect to the adsorption seat 3, avoiding the inclination of the clamping notch 6 caused by the jacking of the lifting seat 7 and the extrusion of the sheet metal part, thereby resulting in insufficient support and positioning of the sheet metal part and poor polishing quality. In addition, the overall shapes of the adsorption seat 3, the clamping seat 5, and the lifting seat 7 can be circular, square, etc., and the clamping notch 6 can also be structures such as circular, square, and irregular. The above structures are all detachably arranged with the docking structure, so as to more fully position sheet metal parts with different shapes.

[0050] The inclination angles of the wedge surfaces on the outer sides of the clamping seats 5 are different, and the wedge ring surface is in close fit with the wedge surface. Based on the adjustable sheet metal part placement cavity design formed by multiple clamping notches 6, by using the clamping seats 5 with wedge surfaces of different inclination angles in cooperation with the wedge structure guidance of the lifting seat 7, it is possible to provide more sufficient support for sheet metal parts with irregular shapes and non-coincident structural mass centers and centers; through the wedge abutting structures with different inclination angles, different support forces can be locally provided to the sheet metal parts on each clamping seat 5. According to the mass distribution of the sheet metal part and the pressure to be applied to the sheet metal part during the polishing position processing, the placement orientation is arranged to ensure the horizontality of the clamping notches 6, so as to achieve sufficient support and positioning of the sheet metal part, and further ensure the polishing quality.

[0051] In addition, wear-resistant layers are provided on the surfaces of the wedge ring surface and the wedge surface. A rubber cushion layer is provided on the surface of the clamping notch 4. While reducing the sliding wear between the clamping seat 5 and the lifting seat 7, the elastic pre-tightening positioning of the surface of the sheet metal part is achieved through the rubber cushion layer, avoiding its displacement during polishing processing and reducing the additional wear between it and the clamping seat 5, ensuring product quality.

[0052] The driving mechanism includes a second lifting driving device 9 positioned in the equipment housing 1, a base 10 positioned at the output end of the second lifting driving device 9, a positioning seat 11 provided below the base 10, and the polishing part 12 rotationally driven by a first rotation driving device 13. Among them, the polishing part 12 is detachably assembled on the first rotation driving device 13. Thus, an appropriate polishing part 12 can be selected based on different sheet metal parts and processing positions to improve the quality of sequential or synchronous polishing of multiple parts of the sheet metal part.

[0053] A second rotation driving device 14 is provided at the bottom of the base 10, the positioning seat 11 is located at the center of the bottom of the second rotation driving device 14, and the polishing part 12 is located outside the positioning seat 11. The above driving devices are one or more of a motor, a cylinder, or a hydraulic cylinder corresponding to the driving movement mode.

[0054] A transparent observation window 15 is provided on the outer side of the processing station 2 of the equipment housing 1. One side of the transparent observation window 15 is hinged to one side of the equipment housing 1, and the other side is locked and positioned on the clamping block on the other side of the equipment housing 1 through a lock. A sealing strip is provided at the docking part of the equipment housing 1 and the end of the transparent observation window 15. This design is used for the isolation of the processing station 2 during the use of the automatic polishing device, the blocking of the debris polished from the sheet metal part, and the realization of the visualization function of the processing process, avoiding its splashing out of the equipment, thereby realizing the centralized collection of processing scraps.

[0055] An adsorption tube is provided on the clamping seat 5. The inlet end of the adsorption tube faces the clamping notch 6, and its outlet end is docked with the collection channel at the top or bottom of the equipment housing 1. The collection channel is docked with an external negative pressure dust storage system. Thereby, the debris and waste generated during polishing are adsorbed, realizing the automatic cleaning of the processing table and the work station, and improving the production efficiency.

[0056] The working principle of an automatic polishing device for the sheet metal parts of a ticket vending machine in this embodiment includes: during use, open the transparent observation window 15, assemble the polishing part 12 on the first rotation drive device 13 according to the model of the product to be processed, place the sheet metal part on the adsorption seat 3, and then close the transparent observation window 15; start the first lifting drive device 8 to lift and lower the lifting seat 7, and cooperate with the elastic part 32 to realize the synchronous opening and closing movement of each clamping seat 5 to clamp the sheet metal part. After completion, the suction cup 4 adsorbs and performs secondary positioning on it; the second lifting drive device 9 drives the positioning seat 11 to move down to the surface of the sheet metal part, the first rotation drive device 13 drives the polishing part 12 to rotate, and the second lifting drive device 9 drives the polishing part 12 to lift and lower synchronously to polish the sheet metal part; after a part of the sheet metal part is completed, the polishing part 12 is rotated by the second rotation drive device 14 to process the next polishing position. After polishing is completed, the drive mechanism lifts to drive the polishing part 12 to move up and reset, the lifting seat 7 resets, and under the elastic force of the elastic part 32, the clamping seat 5 moves outward and resets, releasing the clamping and positioning of the sheet metal part, and releasing the adsorption state of the suction cup 4 on the sheet metal part, which can be realized by supplying air and repressurizing in the suction cup 4. During this period, the negative pressure dust storage system operates, making the collection channel and the adsorption tube form a negative pressure, and sucking in and uniformly collecting and processing the debris and waste generated on the surfaces of the polishing part 12, the clamping notch 6, and the sheet metal part; after polishing and table cleaning, the transparent observation window 15 can be opened to take out the product.

[0057] In summary, due to the adoption of the above technical solutions, an automatic polishing device for the sheet metal parts of a ticket vending machine in this embodiment has the following beneficial effects compared with the prior art:

[0058] 1. The automatic polishing device of the present invention is applied to the processing of the sheet metal parts of a ticket vending machine. The sheet metal part is adsorbed by the adsorption seat, and in cooperation with the lifting and lowering of the lifting seat, wedge-shaped guiding, and elastic pre-tightening of the elastic part, the clamping seat is driven to open and close synchronously to clamp and perform secondary positioning on the product, thereby adapting to the positioning and processing of products of multiple sizes and improving the equipment adaptability; for small-sized sheet metal parts that require fine polishing, the supporting position of the lifting seat for the clamping seat is relatively high, which can provide more sufficient and stable support for the outside of the sheet metal part. For large-sized sheet metal parts, the supporting position of the lifting seat for the clamping seat is relatively low, which can provide sufficient support for the whole sheet metal part to ensure its overall flatness, and thus ensure the polishing quality.

[0059] 2. The design of an adjustable sheet metal part placement cavity formed based on multiple clamping notches. The clamping seats with wedge surfaces of different inclination angles are used in cooperation with the wedge structure guide of the lifting seat, which can provide more sufficient support for sheet metal parts with special shapes and the center of mass not coinciding with the center; through the wedge abutting structures with different inclination angles, different supporting forces can be locally provided to the sheet metal parts on each clamping seat. According to the mass distribution of the sheet metal parts and the pressure to be applied to the sheet metal parts during the polishing position processing, the placement orientation is arranged to ensure the horizontality of the clamping notches, so as to achieve sufficient support and positioning of the sheet metal parts, and further ensure the polishing quality.

[0060] 3. The driving mechanism can rotate and be detachably assembled for the polishing parts, so as to perform sequential or synchronous polishing operations on different polishing positions of the sheet metal parts, improving the processing efficiency.
