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

[0002] Surface treatment is a process that artificially forms a layer on the surface of a substrate material that has different mechanical, physical, and chemical properties from the substrate. The purpose of surface treatment is to meet the requirements of corrosion resistance, wear resistance, decoration, or other special functions of the product. In order to meet the surface roughness requirements of the workpiece, after the workpiece is processed and formed, a polishing machine is needed to polish the surface of the workpiece to remove burrs generated during processing or rust generated during long-term storage.

[0003] However, in existing technologies, in devices that use chains to transport workpieces, the workpiece to be processed is usually mounted on the outer periphery of the conveyor chain, and a support device is set on the inner periphery of the conveyor chain to support the chain and the downward pressure generated by the workpiece during processing. This causes frictional wear between the chain and the support device during transmission. Secondly, the chain is prone to fluctuations during transmission, which is not conducive to the stable processing of the workpiece, resulting in poor transmission effect and affecting the processing quality of the product.

[0004] Therefore, this utility model provides a new technical solution to solve the above problems. Utility Model Content

[0012] The present invention is further configured such that the support plate is inclined relative to the two ends of the conveyor chain, the two support plates in each group are arranged parallel to each other, the support plate is slidably mounted with a slider, and the two ends of the grinding roller are respectively rotatably mounted on the slider.

[0013] The present invention is further configured such that the receiving plate is fixedly connected to multiple support plates on the same side of the conveyor chain, and multiple sets of rollers are rotatably installed on the receiving plate below the grinding roller. The outer periphery of the rollers protrudes from the upper surface of the receiving plate and can abut against the lower end of the carrier to form rolling support.

[0014] The present invention is further configured such that the width of the carrier is greater than the distance between two adjacent rollers.

[0015] The present invention is further configured such that the carrier is horizontally fixedly installed on the outer periphery of the conveyor chain, and the two ends of the carrier protrude from both sides of the conveyor chain, and can be rolledly connected with the rollers rotatably installed on the receiving plate.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment discloses a surface processing apparatus for a workpiece, referring to... Figures 1-7 As shown, the main components include a frame 1, a conveying assembly 2, and multiple grinding rollers 3. The conveying assembly 2 mainly includes two drive shafts 23 and two conveying chains 21. The two drive shafts 23 are arranged in parallel and rotatably mounted on the frame 1. Each of the two drive shafts 23 has two sprockets 24, for a total of four sprockets 24. Two opposing sprockets 24 form a set that can drive the conveying chains 21.

[0029] The conveyor chain 21 has a ring structure and is fitted around the sprockets 24 of the two drive shafts 23. It meshes with two sprockets 24 on different drive shafts 23 to drive the conveyor chain 21. The meshing of the conveyor chain 21 with the sprockets 24 enables the transmission of the conveyor chain 21. One of the drive shafts 23 is driven to rotate by the first motor 25, thereby driving the two conveyor chains 21 to rotate synchronously in a circumferential direction.

[0030] Several carriers 22 are fixedly installed at intervals on the outer periphery of the conveyor chain 21, and the workpiece 4 can be fixedly installed on the upper end of the carrier 22.

[0031] Specifically, the workpiece 4 is a plate material to be processed. A limiting groove 221 matching the shape of the workpiece 4 is provided on the upper end of the carrier 22. Multiple limiting holes 222 are also provided in the limiting groove 221. A limiting block 41 that matches the limiting hole 222 is integrally connected to the lower end of the workpiece 4. The workpiece 4 can be embedded in the limiting groove 221, so that the limiting block 41 passes through the limiting hole 222 to form a limiting installation, so that the workpiece 4 can be stably installed on the carrier 22, which can improve the grinding stability of the workpiece 4. In addition, when the workpiece 4 is embedded in the limiting groove 221, the upper end of the workpiece 4 can partially protrude from the upper end surface of the carrier 22, so that the surface of the workpiece 4 can abut against the outer periphery of the grinding roller 3, thereby achieving stable grinding of the surface of the workpiece 4.

[0032] Reference Figure 2 As shown, multiple sets of support plates 11 are fixedly installed on the frame 1. Each set of support plates 11 includes two support plates 11, which are vertically arranged on both sides of the conveyor chain 21 and parallel to each other. The two support plates 11 are inclined relative to the two ends of the conveyor chain 21. A slider 14 is slidably installed on each support plate 11. The slider 14 is rotatably connected to an adjusting screw 15. The other end of the adjusting screw 15 is threaded to the upper end of the support plate 11. By rotating the adjusting screw 15, the slider 14 can be adjusted vertically relative to the support plate 11. The height of block 14; wherein the two ends of the grinding roller 3 are rotatably mounted on the slider 14 and driven to rotate by the second motor 31. By adjusting the position height of the slider 14 relative to the support plate 11 by adjusting the screw 14, the height of the grinding roller 3 can be adjusted, thereby controlling the distance between the grinding roller 3 and the workpiece 4 to be ground, and realizing the grinding of the surface of the workpiece 4; when the thickness of the workpiece 4 to be ground changes, the height of the grinding roller 3 can be adjusted so that it can abut against the surface of the workpiece 4 for grinding, which can improve the versatility of the grinding device.

[0033] Reference Figure 3 and Figure 4As shown, a support plate 12 is fixedly installed on the inner side of the support plate 11 and on both sides of the conveyor chain 21. The support plate 12 is fixedly connected to multiple support plates 11 on the same side of the conveyor chain 21, forming a stable support structure. Multiple sets of rollers 13 are rotatably installed on the support plate 12 below the grinding roller 3. The outer periphery of the rollers 13 protrudes from the upper end face of the support plate 12. When the carrier 22 carries the workpiece 4 and moves to the lower side of the grinding roller 3 for grinding, both ends of the carrier 22 will move to the upper side of the support plate 12, and can be supported by the support plate 12 and the rollers 13. The rollers 13 can provide vertical support for the carrier 22, making it easy for the grinding roller 3 and the workpiece 4 to make a pressing contact and achieve rolling grinding. They can also form a rolling connection between the carrier 22 and the rollers 13, reducing adverse friction during transmission and improving the transmission reliability of the device and the grinding stability of the workpiece 4.

[0034] Reference Figure 5 and Figure 6 As shown, the width of the carrier 22 is greater than the distance between two adjacent rollers 13 on the same side, so that the lower side of one end of the carrier 22 can stably abut against the upper end of at least one roller 13, and can effectively support one end of the carrier 22.

[0035] Furthermore, since the rollers 13 on the two receiving plates 12 are staggered in the horizontal direction, when the carrier 22 moves to the bottom of the grinding roller 3 for grinding, when one side of the carrier 22 is supported by one roller 13, the other side of the carrier 22 will be supported by two rollers 13. This allows the lower ends of both sides of the carrier 22 to be supported by at least three rollers 13, forming a stable support structure and improving the grinding stability and grinding quality of the workpiece 4. Secondly, the lower ends of the carrier 22 in the length direction are provided with rounded corners, and the two ends of the receiving plate 12 are also provided with inclined surfaces. When the carrier 22 on the conveyor chain 21 is conveyed to the receiving plate 12, it can play a stable transition role and improve the transmission stability.

[0036] Furthermore, to improve the support stability of the receiving plate 12, the width of the carrier 22 can be appropriately increased, so that both ends of the carrier 22 can simultaneously abut against more rollers 13, thereby maintaining more stable operation. Specifically, it can be set according to the width dimension of the workpiece 4.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
