Description

Technical Field

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

[0002] Chamfering refers to the process of cutting the edges of a workpiece into a certain bevel. Chamfering is used to remove burrs produced by machining and to facilitate the assembly of parts. Generally, chamfers are made at the ends of parts. After machining, standard workpieces need to be ground and polished, and the beveled surfaces at the chamfers also need to be ground to meet production requirements.

[0003] Some existing grinding equipment has inaccurate workpiece positioning and slow positioning speed before grinding the chamfer of the workpiece. Moreover, it does not have a protective shell. When grinding the chamfer of the workpiece, the burrs and debris are easy to fly out, causing injury to nearby workers. Furthermore, it is difficult to clean up the flying debris, which is inconvenient to collect. The cleanup is time-consuming and laborious for workers, reducing work efficiency. Utility Model Content

[0004] To facilitate quick positioning and installation of workpieces and to collect flying grinding debris while preventing it from injuring workers, this utility model provides a chamfering grinding device.

[0005] The chamfering and grinding device provided by this utility model adopts the following technical solution: A chamfering and grinding device includes a housing, a clamping structure, a grinding mechanism, and a debris collection structure. The housing has an internal working space with a working surface at its bottom. A positioning groove is provided on the working surface. The clamping structure is slidably connected to the housing, and its sliding direction is parallel to the axis of the positioning groove. The grinding mechanism includes a drive assembly and a grinding element. One end of the grinding element near the working surface has an inclined grinding surface. The drive assembly is mounted on the clamping structure, and the grinding element is rotatably connected to the clamping structure. The drive assembly and the grinding element are drive-driven. The debris collection structure is fixedly connected to the bottom of the housing.

[0006] By adopting the above technical solution, when grinding a workpiece, the workpiece is first placed in the positioning groove on the working surface. The positioning groove is adapted to the workpiece, which can position the workpiece. Then, the clamping structure drives the grinding structure to slide towards the workpiece until the workpiece is clamped. At this time, the inclined grinding surface on the grinding part contacts the chamfer on the upper part of the workpiece, and the workpiece is positioned again. The drive component drives the grinding part to rotate and grinds the chamfer of the workpiece. The grinding debris is blocked by the shell to prevent the debris from flying to the outside and causing injury to the workers. Finally, the debris falls into the debris collection structure at the bottom of the shell, completing the collection of debris. There is no need to clean the working surface, which reduces the workload of the workers, makes the workpiece installation convenient, and improves the grinding efficiency.

[0007] Furthermore, the clamping structure includes a clamping block, which is positioned directly above the positioning groove. Connectors are provided on both sides of the clamping block, and the two connectors are mirror images of each other. The connectors are slidably connected to the housing.

[0008] Furthermore, the clamping block has a top surface, and a cylinder is provided on the upper part of the clamping block. The cylinder has a fixed end and an output end. The fixed end of the cylinder is fixedly connected to the housing, and the output end of the cylinder is fixedly connected to the top surface of the clamping block.

[0009] Furthermore, the drive assembly includes a motor, a first gear, and a second gear. The motor is fixedly connected to the side of the connector away from the working surface. The first gear is disposed on the side of the connector close to the working surface. The motor is connected to the first gear in a transmission manner. The side of the clamping block is provided with a mounting groove. The middle of the second gear is provided with a circular hole that matches the mounting groove. The second gear is rotatably connected to the clamping block. The first gear and the second gear mesh with each other.

[0010] Furthermore, the grinding component is fixedly connected to the side of the second gear near the working surface, and the axis of the grinding component is collinear with the axis of the second gear.

[0011] Furthermore, the uppermost end of the grinding surface of the grinding component and the lowermost end of the clamping block are on the same plane.

[0012] Furthermore, the debris collection structure includes a support frame and a collection component. The support frame is fixedly connected to the bottom of the housing, and the collection component is slidably connected to the support frame. An inlet is provided on the outside of the positioning groove at the bottom of the housing. Multiple fixing rods are provided in the inlet. The working surface on the outside of the inlet is set as an inclined surface, and the height of the working surface increases continuously from the middle to the outside.

[0013] In summary, this utility model has at least one of the following beneficial technical effects: 1. By setting a positioning groove and a grinding element on the housing to position the workpiece, the workpiece is placed into the positioning groove on the working surface. The positioning groove is adapted to the workpiece, which can position the workpiece. At the same time, the clamping block clamps the workpiece, and the inclined grinding surface on the grinding element is in close contact with the chamfer on the upper part of the workpiece, thus performing secondary positioning of the workpiece. The drive component drives the grinding element to rotate and grind the chamfer of the workpiece. The motor starts, and the output shaft of the motor drives the first gear to rotate. The first gear drives the second gear that meshes with it to rotate. The grinding element on the second gear rotates to grind and polish the chamfer on the workpiece. The secondary positioning ensures the accuracy of positioning and improves the quality of grinding.

[0014] 2. By setting up a shell and making the working surface an inclined surface that is high around the edges and low in the middle, the grinding debris is blocked by the shell, preventing the debris from splashing to the outside and causing injury to the workers. Finally, the debris falls onto the working surface at the bottom of the shell. The working surface is inclined, so the debris can slide along the working surface to the feed port and finally fall into the collector, completing the collection of debris. There is no need to clean the working surface, reducing the workload of the workers. Attached Figure Description

[0016] The technical solutions of this utility model are clearly and completely described below through specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] The following combination Figures 1-6 The present invention will be described in further detail below.

[0018] The standard workpiece that needs to be polished is cylindrical, and one end face of the workpiece has a chamfer.

[0019] This embodiment discloses a chamfering and grinding device, referring to... Figures 1-2 The system includes a housing 100 to prevent grinding debris from splashing, a clamping structure 200 to fix the workpiece, a grinding mechanism for grinding the chamfer of the workpiece, and a debris collection structure 400 for collecting grinding debris. When grinding the workpiece, the workpiece is placed inside the housing 100, and the clamping structure 200 moves towards the workpiece to clamp and reposition it. The positioning is quick and accurate. The grinding structure 300 grinds the chamfer of the workpiece. The grinding debris is blocked by the housing 100 and cannot splash out of the housing 100 to cause injury to the workers. The blocked debris falls to the bottom inside the housing 100 and is collected by the debris collection structure 400. There is no need to clean the debris, which reduces the workload of the workers.

[0020] Reference Figures 1-2 In this embodiment, the housing 100 is rectangular in shape, and a working space is provided inside the housing 100. An opening communicating with the working space is provided on the side of the housing 100, and a door panel is provided at the opening. The door panel is rotatably connected to the housing 100. A support leg is provided at the bottom of the housing 100. The bottom of the working space inside the housing 100 has a working surface 110, and a positioning groove 120 is provided in the middle of the working surface 110. The positioning groove 120 is adapted to a standard workpiece, and the workpiece can be positioned for the first time when inserted into the positioning groove 120.

[0021] Thus, the workpiece is placed in the positioning groove 120 on the working surface 110. The positioning groove 120 is adapted to the workpiece and can position the workpiece. The housing 100 can block the flying grinding debris.

[0022] Reference Figures 1-4In this embodiment, the clamping structure 200 is slidably connected to the housing 100. The sliding direction of the clamping structure 200 is parallel to the axial direction of the positioning groove 120. The clamping structure 200 includes a clamping block 210. Connectors 220 are provided on both sides of the clamping block 210. The two connectors 220 are mirror images of each other. The connectors 220 are slidably connected to the housing 100. Specifically, sliders are provided on the end faces of the two connectors 220 near the housing 100. A sliding groove is provided on the inner side of the housing 100. The sliding groove is longitudinally arranged. The slider is disposed inside the sliding groove and can slide within the sliding groove.

[0023] The clamping block 210 has a top surface, and a cylinder 230 is provided on the upper part of the clamping block 210. The cylinder 230 has a fixed end and an output end. The fixed end of the cylinder 230 is fixedly connected to the housing 100, and the output end of the cylinder 230 is fixedly connected to the top surface of the clamping block 210.

[0024] Thus, after the workpiece is placed in the positioning groove 120, the cylinder 230 works, and the cylinder 230 drives the clamping block 210 to move towards the workpiece. The connecting piece 220 of the clamping block 210 slides longitudinally along the housing 100 until it abuts against the workpiece and fixes the workpiece. The positioning and fixing of the workpiece is very convenient and saves a lot of time in fixing the workpiece.

[0025] Reference Figures 2-3 , Figures 5-6 In this embodiment, the grinding mechanism includes a drive assembly 310 and a grinding component 320. The grinding component 320 has an inclined grinding surface 321 at one end near the working surface 110. The drive assembly 310 is mounted on the clamping structure 200, and the grinding component 320 is rotatably connected to the clamping structure 200. The drive assembly 310 and the grinding component 320 are connected by a transmission.

[0026] The drive assembly 310 includes a motor 311, a first gear 312, and a second gear 313. The motor 311 is fixedly connected to the side of the connector 220 away from the working surface 110. The first gear 312 is disposed on the side of the connector 220 close to the working surface 110. The motor 311 and the first gear 312 are connected in a transmission manner. The clamping block 210 has a mounting groove 211 on its side. The second gear 313 has a round hole in the middle that matches the mounting groove 211. The second gear 313 is rotatably connected to the clamping block 210. The first gear 312 and the second gear 313 mesh with each other. The grinding part 320 is fixedly connected to the side of the second gear 313 close to the working surface 110. The axis of the grinding part 320 is collinear with the axis of the second gear 313. The uppermost end of the grinding surface 321 of the grinding part 320 is on the same plane as the lowermost end of the clamping block 210.

[0027] Thus, while the clamping block 210 clamps the workpiece, the inclined grinding surface 321 on the grinding component 320 makes close contact with the chamfer on the upper part of the workpiece, performing secondary positioning of the workpiece. The drive assembly 310 drives the grinding component 320 to rotate, grinding the chamfer of the workpiece. Specifically, the motor 311 starts, and the output shaft of the motor 311 drives the first gear 312 to rotate. The first gear 312 drives the second gear 313 meshing with it to rotate. The grinding component 320 on the second gear 313 rotates to grind and polish the chamfer on the workpiece. The secondary positioning ensures the accuracy of positioning and improves the quality of grinding.

[0028] Reference Figures 1-2 In this embodiment, the debris collection structure 400 is fixedly connected to the bottom of the housing 100. The debris collection structure 400 includes a support frame 410 and a collection component 420. The support frame 410 is fixedly connected to the bottom of the housing 100, and the collection component 420 is slidably connected to the support frame 410. An inlet 130 is provided on the outside of the positioning groove 120 at the bottom of the housing 100. A plurality of fixing rods 140 are provided in the inlet 130. The working surface 110 on the outside of the inlet 130 is set as an inclined surface, and the height of the working surface 110 increases continuously from the middle to the outside.

[0029] In this way, the grinding debris is blocked by the housing 100, preventing it from flying to the outside and causing injury to the workers. Finally, the debris falls onto the working surface 110 at the bottom of the housing 100. The working surface 110 is inclined, allowing the debris to slide along the working surface 110 into the feed inlet 130 and finally fall into the collector 420, completing the collection of debris. There is no need to clean the working surface 110 again, reducing the workload of the workers.

[0030] The implementation principle of this embodiment is as follows: The workpiece is placed into the positioning groove 120 on the working surface 110. The positioning groove 120 is adapted to the workpiece and can position the workpiece. The housing 100 can block flying grinding debris. After the workpiece is placed in the positioning groove 120, the door panel is closed, and the cylinder 230 is activated. The cylinder 230 drives the clamping block 210 to move towards the workpiece. The connecting piece 220 of the clamping block 210 slides longitudinally along the housing 100 until it abuts against the workpiece, fixing the workpiece. At the same time, the inclined grinding surface 321 on the grinding piece 320 is in close contact with the chamfer on the upper part of the workpiece, performing secondary positioning of the workpiece. The drive assembly 310 drives the grinding piece 320 to rotate, grinding the chamfer of the workpiece. Specifically, the motor 311 starts, and the output shaft of the motor 311 drives the first gear 312 to rotate. The first gear 312 drives the second gear 313, which meshes with it, to rotate. The grinding part 320 on the second gear 313 rotates to grind and polish the chamfer on the workpiece. The grinding debris is blocked by the housing 100 to prevent the debris from flying to the outside and causing injury to the workers. Finally, the debris falls onto the working surface 110 at the bottom of the housing 100. The working surface 110 is inclined, and the debris can slide along the working surface 110 into the feed port 130 and finally fall into the collector 420 to complete the collection of debris. Finally, the cylinder 230 works to drive the clamping block 210 away from the workpiece and take out the ground workpiece.

[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
