[0072] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0073] The grinding device provided in this application is applicable to, but not limited to, grinding of lifting components and straps such as latches in railway freight car braking systems.

[0074] Please see Figures 1-5 , Figure 1 This is an isometric schematic diagram of a grinding device according to a specific embodiment of the present invention; Figure 2 for Figure 1 Front view diagram; Figure 3 for Figure 1 Side view; Figure 4 This is a schematic diagram of the split structure of the chute; Figure 5 for Figure 4 Side view.

[0075] In one embodiment, the grinding apparatus provided by the present invention includes a base frame assembly 100, a conveying system assembly 200, and a grinding head assembly 300. The base frame assembly 100 includes a support assembly 110 and a slide groove assembly 120. The support assembly 110 is the main support structure, and the slide groove assembly 120 is disposed on the support assembly 110. The slide groove assembly 120 has a longitudinally extending slide groove 1213 to limit the workpiece. The shape and size of the slide groove 1213 are set according to the workpiece and are not specifically limited here. The conveying system assembly 200 is disposed on the support assembly 110 and is used to drive the workpiece to slide along the slide groove 1213. The grinding head assembly 300 includes a roller brush 310 and a roller brush 310 grinding drive component 320. The roller brush 310 is rotatably connected to the support assembly 110, and the grinding drive component 320 is used to drive the roller brush 310 to rotate to grind the workpiece.

[0076] Using the grinding device provided by this invention, the workpiece to be ground is placed in the slide groove 1213 of the slide groove assembly 120. The grinding drive component 320 drives the roller brush 310 to rotate, thereby enabling the roller brush 310 to grind the workpiece. The conveying system assembly 200 can drive the workpiece to move along the slide groove 1213, so that each part of the workpiece can pass through the roller brush 310 in sequence to complete the overall grinding. In summary, the grinding device provided by this application can realize automatic grinding of workpieces, significantly improving grinding efficiency and reducing labor intensity compared with manual angle grinder grinding.

[0077] In one embodiment, the chute assembly 120 includes two opposing chute sections 121, each with a chute 1213 for limiting the workpiece on its opposite sides. By limiting the workpiece on both sides through the two chute sections 121, the conveying system 200 can act on the workpiece between the two chute sections 121, driving the workpiece to move. Furthermore, by supporting and limiting the workpiece from both sides, the workpiece moves smoothly. In other embodiments, the chute assembly 120 can also be a single unit, allowing the conveying system 200 to move the workpiece by pulling or pushing.

[0078] In one embodiment, see Figure 4 and Figure 5The slide groove 121 includes a slide rail 1211 and a limiting member 1212. The slide rail 1211 supports the workpiece. The limiting member 1212 and the slide rail 1211 form a slide groove 1213. The limiting member 1212 includes a vertical portion 1212-1 located outside the slide rail 1211 and a horizontal portion 1212-2 located above the slide rail 1211. The horizontal portion 1212-2 connects to the vertical portion 1212-1, and a clearance hole 1212-3 is provided at the connection point, allowing the roller brush 310 to pass through the clearance hole 1212-3 to act on the workpiece. It can be understood that the outer side of the slide rail 1211 refers to the side of one of the two slide rails 1211 that is furthest from the other. The workpiece is placed on the slide rail 1211. The vertical part 1212-1 can limit the outer side of the workpiece, and the horizontal part 1212-2 can limit the upper side of the workpiece, thereby preventing the workpiece from moving within the slide groove 1213. A clearance through hole 1212-3 is provided at the connection between the horizontal part 1212-2 and the vertical part 1212-1, so that the roller brush 310 can pass through the clearance through hole 1212-3 to grind the side of the workpiece. The number and width of the clearance through holes 1212-3 can be set as needed. Preferably, multiple clearance through holes 1212-3 are provided corresponding to the position of the roller brush 310 to improve grinding efficiency. Specifically, a guide rail 1214 can be provided on the support assembly 110, and the limiting member 1212 is provided on the guide rail 1214. The limiting member 1212 can be fixed to the support assembly 110 by a guide block and a guide sleeve, or it can be fixed to the support assembly 110 by welding or other methods. The slide rail 1211 can also be fixed to the bracket assembly 110 by welding or other means. In order to facilitate the workpiece to enter the slide groove 1213 along the slide rail 1211 under the drive of the grinding drive component 320, the end of the limiting component 1212 can be flared.

[0079] In one embodiment, see Figure 6 and Figure 7The support assembly 110 includes a first support 111 and two second supports 112. The two second supports 112 are arranged opposite to each other, and at least one second support 112 is a movable support that is laterally slidable on the first support 111. Two sliding groove components 121 are respectively connected to the two second supports 112. The grinding head assembly 300 is connected to either the first support 111 or the second support 112. The first support 111 is a fixed support, and at least one second support 112 is a movable support. By laterally moving the movable support, the distance between the two second supports 112 can be adjusted, thereby adjusting the distance between the two sliding groove components 121 to accommodate workpieces of different widths. When the grinding head assembly 300 is connected to the movable support, it can move synchronously with the movable support to accommodate workpieces of different widths. When the grinding head assembly 300 is connected to the first support 111, one of the two second supports 112 is a movable support, and the other is a fixed support. The grinding head assembly 300 can cooperate with the side of the fixed support to grind the corresponding side of the workpiece. The above settings make the grinding device more versatile.

[0080] In one embodiment, see Figure 8 and Figure 9 The first support 111 includes a first steel structure 1111, a guide connecting plate 1112, a support slide rail 1113, and a bearing seat connecting plate 1114. The guide connecting plate 1112, the support slide rail 1113, and the bearing seat connecting plate 1114 are all located on the first steel structure 1111. The first steel structure 1111 can be a welded structure of shaped steel and plate, and can be fixed to the ground or a support platform; the guide connecting plate 1112 is used to connect a guide assembly 140 that guides the lateral movement of the second support 112 relative to the first support 111; the support slide rail 1113 is used to support the conveying system component 200, such as supporting the chain 213 drive of the conveying system component 200; the bearing seat connecting plate 1114 is used to connect the bearing seats of the conveying system component 200.

[0081] In one embodiment, see Figure 10 and Figure 11 The second support 112 includes a second steel structure 1121, a dust collection box 1122, and a swivel bearing seat 1123. The second steel structure 1121 can be a welded structure of steel profiles and plates, and can move laterally on the first support 111; the dust collection box 1122 can collect the waste generated during grinding; the swivel bearing seat 1123 is used to mount the grinding head assembly 300, such as the swivel arm frame 330 of the grinding head assembly 300. Furthermore, the swivel bearing seat 1123 is provided with adjusting screws at both ends for fine adjustment of the lateral position of the grinding head assembly 300.

[0082] In one embodiment, see Figure 12The base frame assembly 100 also includes a width adjustment component 130 connected to the movable support to drive the movable support to move laterally. That is, the width adjustment component 130 drives the movable support to move laterally along the first support 111. The width adjustment component 130 can be a device that can output driving force to drive the movable support to move automatically, such as a telescopic cylinder, or it can be a manually adjustable structure.

[0083] In one embodiment, the width adjustment assembly 130 includes an adjustment seat 131 and a connecting rod 132. The adjustment seat 131 is mounted on a movable bracket and has a threaded through hole. The connecting rod 132 is laterally mounted on a first bracket 111 and has external threads that pass through the threaded through hole. Rotation of the connecting rod 132 causes the adjustment seat 131 to move laterally along the connecting rod 132, thereby adjusting the distance between the two second brackets 112. The threaded engagement provides reliable transmission, and the position of the adjustment seat 131 is continuously adjustable. Specifically, the thread may have a self-locking function, allowing the adjustment seat 131 to be easily locked in its current position. To facilitate rotation of the connecting rod 132, in one embodiment, a handwheel 133 is provided at the end of the connecting rod 132, allowing the operator to rotate the connecting rod 132. In other embodiments, the end of the connecting rod 132 may also be connected to a drive device such as a motor to rotate under the drive of the drive device.

[0084] In one embodiment, both second supports 112 are movable supports, and each movable support is equipped with two adjusting seats 131. The threads of the two adjusting seats 131 that engage with the connecting rod 132 have opposite directions, so that the two adjusting seats 131 move laterally inward or outward synchronously with the rotation of the connecting rod 132. As configured above, when the connecting rod 132 rotates, the two adjusting seats 131 at both ends can move towards each other (inward) or away from each other (outward), thereby driving the two second supports 112 on them to move towards each other or away from each other to accommodate workpieces of different widths. The synchronous movement of the two adjusting seats 131 results in high adjustment efficiency. Furthermore, a tie rod seat 134 can be provided to cooperate with the tie rod. The connecting rod 132 is rotatably mounted on the tie rod seat 134, and the tie rod seat 134 is fixed to the first support 111. The tie rod seat 134 facilitates the installation of the connecting rod 132.

[0085] In one embodiment, see Figure 13 and Figure 14The base frame assembly 100 also includes a guide assembly 140, which includes a first support connector 141, a second support connector 142, and a guide member 143. The first support connector 141 is connected to the first support 111; the second support connector 142 is connected to the movable support; the guide member 143 is connected to the first support connector 141, and the guide member 143 and the first support connector 141 form a guide groove 144. The second support connector 142 is inserted into the guide groove 144 and can slide along the guide groove 144. During the lateral movement of the movable support, the second support 112 moves along the guide groove 144 to limit and guide the movement of the movable support. Specifically, the first support connector 141 and the first support 111 can be connected by bolts or welding, and the second support connector 142 and the movable support can specifically be connected by bolts or welding. The guide member 143 can be L-shaped, with one side connected to the first bracket connector 141 and the other side opposite to the first bracket connector 141. This allows it to guide and limit the movement of the movable bracket on the second bracket connector 142 in the vertical direction and on the side, making the movement of the movable bracket on the second bracket connector 142 more stable.

[0086] Furthermore, a bolt hole is provided at the end of the guide member 143 opposite to the first bracket connector 141. When the movable bracket moves into place relative to the first bracket 111, the second bracket connector 142 can be pressed onto the first bracket connector 141 by tightening the bolt, thereby locking the movable bracket in the current position.

[0087] In one embodiment, see Figure 15 and Figure 16 The base assembly 100 also includes a height adjustment component 150, which is connected to the grinding head assembly 300 to drive the roller brush 310 closer to or further away from the slide groove assembly 120. By adjusting the height adjustment component 150, the distance between the roller brush 310 and the slide groove assembly 120 can be adjusted to accommodate workpieces of different heights, thus improving the versatility of the grinding device.

[0088] In one embodiment, the grinding head assembly 300 further includes a rotating arm 330, the middle of which is rotatably connected to the support assembly 110. The roller brush 310 is rotatably connected to the first end of the rotating arm 330. The height adjustment assembly 150 includes a lifting mechanism 151, one end of which is rotatably connected to the second end of the rotating arm 330, and the other end of which is rotatably connected to the support assembly 110. By raising and lowering the lifting mechanism 151, one end of the rotating arm 330 swings up and down, and the other end swings in the opposite direction to move closer to or further away from the slide rail assembly 120, thus accommodating workpieces of different heights. The height adjustment of the roller brush 310 is achieved by rotating the rotating arm 330, requiring less driving force and facilitating operation. In other embodiments, the roller brush 310 can also be slidably installed in the vertical direction, and a telescopic cylinder or similar device can be used to drive the roller brush 310 up and down to adjust its distance from the slide rail assembly 120.

[0089] In one embodiment, the lifting mechanism 151 includes a lead screw 1511 and two nuts 1512. The two nuts 1512 are threadedly engaged with the lead screw 1511, with opposite rotation directions. The top nut 1512 is rotatably connected to the second end of the boom 330, and the bottom nut 1512 is rotatably connected to the support assembly 110. Specifically, the nuts 1512 and the boom 330 are rotatably connected via pins 155. When the height of the grinding head assembly 300 needs to be adjusted, rotating the lead screw 1511 causes the two nuts to move in opposite directions, and the top nut 1512 drives the second end of the boom 330 to swing up and down, thereby causing the first end of the boom 330 to swing the grinding head assembly 300 in the opposite direction. The lead screw 1511 and nuts 1512 have a simple structure and allow for continuous height adjustment. To facilitate the rotation of the lead screw 1511, an operating hole can be provided on the lead screw 1511, and an operating rod or the like can be inserted into the operating hole to easily rotate the lead screw 1511. In other embodiments, the lifting mechanism 151 may also adopt a gear and rack structure, or a telescopic drive device.

[0090] In one embodiment, the height adjustment assembly 150 further includes a connecting seat 152, a lever arm 153, and a locking component 155. The connecting seat 152 is disposed on the bracket assembly 110; one end of the lever arm 153 is rotatably connected to the connecting seat 152, and the other end is rotatably connected to the bottom end of the lifting mechanism 151; the locking component 154 is used to lock the lever arm 153 to the connecting seat 152. The lever arm 153, the lead screw 1511, and the rotating arm frame 330 can form a linkage mechanism. By rotating the lever arm 153, the lifting mechanism 151 is driven to rotate, and the rotating arm frame 330 is driven to rotate to a certain angle, such as a vertical position, thereby facilitating the maintenance of the roller brush 310 on the rotating arm frame 330. The locking component 154 can specifically be a movable pin. A through hole is provided on the lever arm 153, and through holes can be provided on the connecting seat 152 corresponding to the working position and the maintenance position, respectively. When the lever arm 153 rotates to the working position, the movable pin is inserted to lock the lever arm 153 to the connecting seat 152, thereby allowing the grinding head assembly to adjust its height under the action of the lifting mechanism 151 and ensuring the safety of the grinding process. When maintenance is required, the movable pin is first pulled out, the lever arm 153 is rotated to the maintenance position, and then the movable pin is inserted again to lock the grinding head assembly 300 in the retrieval position for easy maintenance. The locking component 154 can also be a latch or other locking parts. A handle fixedly connected to the lever arm 153 can be provided to facilitate rotation of the lever arm 153.

[0091] In one embodiment, two grinding heads 300 are arranged opposite each other on both sides of the slide assembly 120. By providing two grinding heads 300, the opposite sides of the workpiece can be ground simultaneously, improving grinding efficiency. When the slide assembly 120 includes two oppositely arranged slide sections 121, the two grinding head assemblies 300 are respectively positioned corresponding to the two slide sections 121. When the support assembly 110 includes two second supports 112, the two grinding head assemblies are respectively mounted on the two second supports 112.

[0092] In one embodiment, see Figure 17 and Figure 18The grinding head assembly 300 includes a pulley 340, a pulley shaft 350, a belt 360, a swing arm 330, a bearing 370, a motor, a sliding groove 380, and a roller brush 310. During operation, the motor drives the pulley 340 to rotate, and the pulley 340 drives the roller brush 310 to rotate and grind the product via the belt 360. The swing arm 330 can be a welded structure of steel profiles and plates, used to connect various moving parts. The swing arm 330 is rotatably connected to the support assembly 110 via the bearing 370. Furthermore, the grinding head assembly 300 also includes a roller brush cover 311 and / or a belt cover 361. The roller brush cover 311 is rotatably connected to the swing arm 330 to cover the roller brush 310 for protection, while also preventing sparks from flying during grinding.
