[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection.

[0020] In the description of the embodiments, it should be understood that terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the embodiments.

[0021] like Figure 1 As shown, in an embodiment of the present invention, a grinding device for processing hardware pliers is provided, aiming to improve the grinding efficiency of the pliers head. The device mainly includes a grinding box 10 and a loading frame 20.

[0022] A grinding window 100 is provided on the grinding box 10 , a grinder 30 is installed in the grinding box 10 corresponding to the grinding window 100 , and a plurality of clamping seats 211 for installing clamps are provided on the loading frame 20 corresponding to the grinding window 100 .

[0023] Furthermore, two groups of grinders 30 are symmetrically arranged along the grinding window 100 in the grinding box 10 for grinding both sides of the clamp. The loading frame 20 includes a loading column 21 and a second driver 22. Multiple clamping seats 211 are rotatably installed on the loading column 21. The second driver 22 is configured to drive multiple clamping seats 211 to rotate at the same time, so that the clamp can be deflected by a set angle, so that the two ungrinded sides of the clamp can continue to be grinded by the grinder 30.

[0024] In some embodiments, a plurality of clamping seats 211 are provided on the loading column 21 along the height direction. The clamping seat 211 is constructed as a disc-shaped seat, and a bearing is installed between the clamping seat 211 and the loading column 21 so that the clamping seat 211 can rotate on the loading column 21, and each clamping seat 211 is provided with a clamping hole 210 for installing pliers. The clamping holes 210 are arranged in pairs and can install the handles of the pliers.

[0025] like Figure 3As shown, further, each clamping seat 211 is provided with a protruding second linkage gear 212, and the output end of the second driver 22 is provided with a second linkage rack 221 meshing with multiple second linkage gears 212. The second linkage gear 212 can drive the second linkage rack 221 to move and drive multiple second linkage gears 212 to rotate to adjust the angle of the clamp on the clamping seat 211 in the working area 311, wherein the second driver 22 can adopt an electric actuator or a pneumatic reciprocating cylinder to drive the second linkage rack 221 to reciprocate within a certain distance, and through the meshing cooperation between the second linkage rack 221 and the second linkage gear 212, the clamping seat 211 is driven to rotate within a set angle. Since the pliers head usually has four surfaces, the rotation angle is set to ninety degrees, so that after grinding two surfaces, the pliers head rotates ninety degrees and then grinds the other two surfaces.

[0026] In this way, during the grinding process, the grinding box 10 grinds the two sides of the pliers in advance. After the grinding is completed, the loading frame 20 drives the pliers to rotate ninety degrees, and the grinding box 10 grinds the other two sides of the pliers. During the entire grinding process, there is no need to manually adjust the angle of the pliers, which can simplify the grinding steps of the pliers and improve the efficiency of grinding the pliers.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, in order to further improve the grinding efficiency of the clamp, the loading column 21 is set to a prism, and the cross-sectional shape of the loading column 21 is set to a triangle, a quadrilateral or a hexagon. A base 23 is provided at the bottom of the second driver 22, so that a plurality of clamping seats 211 are within the height range of the grinding window 100, and the second driver 22 is rotatably connected to the base 23, so that a plurality of side surfaces of the loading column 21 can be rotated to the front side of the grinding window 100. In this way, when grinding, the grinding box 10 can grind the clamp installed on the side of the loading frame 20 facing the grinding window 100, while the other sides can be loaded and unloaded. After the grinding of one side is completed, the installed but ungrinded clamp is rotated into the grinding window 100, thereby reducing the downtime and greatly improving the grinding efficiency.

[0028] like Figure 4 As shown, the grinding box 10 includes a box shell 11 and a first driver 12. A grinding chamber 110 is provided inside the box shell 11. A grinding window 100 is arranged on the box shell 11, and the grinding window 100 is communicated with the grinding chamber 110. The grinder 30 includes a driving wheel 32 rotatably installed in the grinding chamber 110 and a grinding belt 31 sleeved on the outside of the driving wheel 32. The first driver 12 drives the driving wheel 32 to rotate, driving the outer grinding belt 31 to circulate, so as to grind the clamp inserted into the grinding window 100. The position of the grinding belt 31 corresponding to the grinding window 100 is set as a working area 311.

[0029] Furthermore, an output shaft 1211 is provided at the output end of the transmission box 121, and a driving wheel 32 is fixedly connected to the output shaft 1211, and the driving wheel 32 drives the grinding belt 31 to transmit. When working, the output shaft 1211 at the output end of the first driver 12 drives the driving wheel 32 to rotate, so that the grinding belt 31 mounted on the outside of the driving wheel 32 is circulated. When the pliers is placed between the two grinding belts 31 in the grinding window 100, the working area 311 of the grinding belt 31 contacts the pliers and grinds the surface of the pliers to make the rough surface of the pliers smooth.

[0030] Since the pliers have a bevel side (pointed nose) and a flat side, and the widths of the bevel side and the flat side of the pliers are inconsistent, when the pliers are polished, the spacing and shape between the two polishing belts 31 are also inconsistent. In order to make the spacing between the two polishing belts 31 adaptively adjusted according to the width of the pliers and adapt to the bevel or flat surface.

[0031] like Figure 4 As shown, a clamping plate 50 is provided on the inner side of each grinding belt 31 in the grinding chamber 110 , and the first driver 12 can drive the two groups of clamping plates 50 to move relative to each other to adjust the distance between the two working areas 311 .

[0032] like Figure 5 and Figure 6 As shown, in some embodiments, a transmission cavity 111 is provided on the rear side of the box shell 11 corresponding to the grinding cavity 110, and a transmission box 121 is provided in the transmission cavity 111 and is connected to the output end of the first driver 12. The transmission box 121 is configured to drive the two sets of linkage frames 14 to move in directions that are close to or away from each other at the same time.

[0033] Furthermore, a double-headed screw shaft 1212 is provided at the output end of the transmission box 121, and the two linkage frames 14 respectively transmit the two transmission parts installed on the double-headed screw shaft 1212. Specifically, a sleeve is provided at the connection between the linkage frame 14 and the double-headed screw shaft 1212, and the sleeve is meshed with the double-headed screw shaft 1212 for transmission, and a guide cylinder is provided at the lower part of the linkage frame 14, so that the two groups of linkage frames 14 can only move in the direction of approaching or moving away from each other. When the transmission box 121 drives the double-headed screw shaft 1212 to rotate, the two linkage frames 14 are moved closer to or away from each other.

[0034] Furthermore, a rotating shaft 141 is rotatably installed on the linkage frame 14, and one end of the rotating shaft 141 extends into the grinding chamber 110 and is fixedly connected to a clamping plate 50. In this way, when the linkage frame 14 moves, the clamping plate 50 on the inner side of the grinding belt 31 is driven to move, so as to adjust the distance between the two working areas 311 on the grinding belt 31.

[0035] At the same time, in order to ensure that the grinding belt 31 always has the elastic force to recover, the grinder 30 also includes a tensioning wheel 33. The tensioning wheel 33 is arranged on the outside of the grinding belt 31 and away from the side of the working area 311. The tensioning wheel 33 is rotatably installed in the box shell 11, and the tensioning wheel 33 can move elastically in the direction perpendicular to the working area 311. In this way, by adjusting the position of the tensioning wheel 33, a telescopic margin is provided for the position change of the working area 311 of the grinding belt 31, and the grinding belt 31 can be tightly attached to the surface of the splint 50. When grinding the workpiece, it can be stably pressed against the surface of the workpiece to achieve a stable grinding effect.

[0036] Furthermore, in order to make the clamp 50 adapt to the inclined side and the flat side of the pliers, the clamp 50 includes a first clamping surface 51 adapted to the inclined side of the pliers and a second clamping surface 52 adapted to the flat side of the pliers. When the inclined side of the pliers is located between the two working areas 311, the first clamping surface 51 is located on the inner side of the working area 311, and the working area 311 is fitted to the inclined side of the pliers for grinding. When the flat side of the pliers is located between the two working areas 311, the second clamping surface 52 is located on the inner side of the working area 311, and the working area 311 is fitted to the flat side of the pliers for grinding.

[0037] like Figure 8 and Fig. 9 As shown, in some embodiments, the clamp 50 is configured as a rectangular plate, the first clamping surface 51 and the second clamping surface 52 are respectively located on both sides of the rectangular plate, a first linkage gear 142 is fixedly mounted on the rotating shaft 141, a linear actuator 15 is fixedly mounted on the linkage frame 14, and an output end of the linear actuator 15 is provided with a first linkage rack 151 for driving the rotating shaft 141 to rotate, and according to the inclined side or the flat side of the clamp, the first clamping surface 51 or the second clamping surface 52 is rotated to the inner side of the working area 311 so that the working area 311 fits with the surface of the clamp.

[0038] Among them, the linear actuator 15 can adopt an electric actuator or a pneumatic reciprocating cylinder, and the linear actuator 15 is used to drive the first linkage rack 151 to perform linear reciprocating motion, driving the first linkage gear 142 to rotate, so that the first clamping surface 51 or the second clamping surface 52 of the clamping plate 50 is placed on the inner side of the working area 311 of the grinding belt 31.

[0039] It should be understood that the first clamping surface 51 in the scheme can only be adapted to the inclined side of one type of pliers. When the type or size of the pliers is adjusted, different clamps 50 should be installed to make the replaced first clamping surface 51 adapt to the replaced inclined side of the pliers. The inclined side of a general pliers has a bevel, a trapezoidal bevel or an arc-shaped edge.

[0040] like Figure 5 and Figure 7As shown in the figure, a smoke exhaust device 40 is provided between two working areas 311 in the grinding chamber 110. The cross-section of the smoke exhaust device 40 is set in a "C" shape or a "V" shape. Every two horizontally symmetrically arranged clamping plates 50 form a group. The number and height position of the clamping plate groups 50 correspond to those of the clamping seats 211. The smoke exhaust device 40 is provided in multiple numbers, and the smoke exhaust device 40 is located below each group of clamping plates 50.

[0041] Furthermore, a circulating liquid supply device 13 is fixedly provided at the bottom of the box housing 11. Above the circulating liquid supply device 13, a liquid extraction pipe 131 and a liquid supply pipe 132 are respectively fixedly connected and extend into the transmission chamber 111. Among them, a liquid pumping device and a liquid extraction device are provided inside the circulating liquid supply device 13. The liquid pumping device and the liquid extraction device are respectively connected to the liquid supply pipe 132 and the liquid extraction pipe 131. And a filter is provided inside the circulating liquid supply device 13 for filtering the particulate impurities generated during grinding.

[0042] Even further, the smoke exhaust device 40 includes a smoke exhaust hopper 41. The bottom of the smoke exhaust hopper 41 is connected to the liquid extraction pipe 131 through a liquid discharge pipe 42. The top of the smoke exhaust hopper 41 is connected to the liquid supply pipe 132 through a liquid supply hose 43. A mist spray head 411 is fixedly provided at the top end of the side wall of the smoke exhaust hopper 41. The mist spray head 411 is communicated with the liquid supply hose 43 and can spray water mist into the smoke exhaust hopper 41. During operation, the liquid pumping device in the circulating liquid supply device 13 transports water to the mist spray head 411 through the liquid supply pipe 132, and after being atomized by the mist spray head 411, it is sprayed onto the inner side of the smoke exhaust hopper 41, collecting the dust generated during grinding into the smoke exhaust hopper 41, and then discharging it into the circulating liquid supply device 13 through the liquid discharge pipe 42 connected to the bottom of the smoke exhaust hopper 41. Circulating like this can prevent the dust during grinding from spreading into the working environment.

[0043] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0044] The above describes the implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the creative purpose, and design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope.
