Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and specifically discloses a product grinding clamping device with dust collection function. Background Technology

[0002] Grinding devices are mechanical tools or equipment used to grind, polish, or deburr the surface of workpieces. They are widely used in woodworking, metal processing, plastics processing, ceramics manufacturing, and other fields. Depending on different processing needs, grinding devices can be divided into manual tools (such as sandpaper and files), power tools (such as angle grinders and belt sanders), and automated equipment (such as CNC grinding machines).

[0003] Before grinding, a clamping device is needed to fix the workpiece. Existing clamping devices generally fix the workpiece in one direction, which is not secure enough. Moreover, dust is easily generated during grinding, which affects the health of the operators. Therefore, a grinding clamping device with dust collection function is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a product grinding clamping device with dust collection function. Through a four-way linkage clamping mechanism driven by a single electric push rod and a negative pressure dust collection system, it realizes the adaptive and firm clamping of workpieces and the efficient collection of grinding dust. It has the advantages of compact structure, simple operation and environmental protection.

[0005] This utility model is implemented as follows: a product grinding and clamping device with dust collection function includes a worktable. The worktable is equipped with a dust collection mechanism and a clamping mechanism. The clamping mechanism includes four L-shaped rods that pass through and are slidably connected to the inner wall of the worktable. Clamping plates are fixedly connected to the near ends of the L-shaped rods. A sleeve is passed through and rotatably connected to the bottom surface of the worktable. A rotating shaft is rotatably connected to the inner wall of the sleeve. Two first connecting rods are fixedly connected to the outer wall of the sleeve and the outer wall of the rotating shaft. The other ends of the four first connecting rods are rotatably connected to second connecting rods. The other ends of the four second connecting rods are rotatably connected to the lower ends of the four L-shaped rods respectively.

[0006] As a preferred embodiment of the dust collection function product grinding clamping device of this utility model, the clamping mechanism further includes a first gear fixedly connected to the lower end of the outer wall of the sleeve and the lower end of the outer wall of the rotating shaft respectively. Mounting plates are fixedly connected to both the front and rear sides of the lower end face of the worktable. Two second slide rods are fixedly connected to both the upper and lower sides between the two mounting plates. Slide plates are slidably connected to the outer walls of the two second slide rods at the same height. A first spur rack that meshes with the first gear is fixedly connected to the outer walls of the two slide plates.

[0007] An electric actuator is installed on the rear end face of the mounting plate located on the front side. The output end of the electric actuator is fixedly connected to a gantry frame. A second gear is rotatably connected to the inner wall of the gantry frame. A second spur rack that meshes with the second gear is fixedly connected to the outer walls of the two opposing slide plates.

[0008] As a preferred embodiment of the dust collection function of this utility model for product grinding and clamping device, the dust collection mechanism includes an air cavity fixedly connected to the upper surface of the workbench. The upper surface of the workbench has multiple through holes communicating with the air cavity. The outer wall of the workbench is provided with a collection box communicating with the air cavity through a pipe. The collection box has a drawer movably arranged inside. The lower end of the outer wall of the drawer is provided with a filter screen. The outer wall of the workbench is equipped with a suction fan with an air inlet communicating with the collection box.

[0009] As a preferred embodiment of the dust collection function product grinding and clamping device of this utility model, the air inlet of the suction fan is located on the lower side of the filter screen.

[0010] As a preferred embodiment of the present invention, a product grinding and clamping device with dust collection function, rubber pads are provided on the outer walls of the multiple clamping plates that are close to each other.

[0011] As a preferred embodiment of the dust collection function product grinding clamping device of this utility model, two first sliding rods are fixedly connected to the inner wall of the workbench and the outer wall of the air cavity around the perimeter, and four L-shaped rods are slidably connected to eight first sliding rods respectively, and a sliding groove is provided through the upper end surface of the workbench.

[0012] As a preferred embodiment of the dust collection function of this utility model, a controller is provided on the outer wall of the workbench, and the suction fan and the electric push rod are both electrically connected to the controller.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses a gear and rack transmission and linkage mechanism linkage design to achieve synchronous or step-by-step clamping of four clamping plates with only a single electric push rod. When some clamping plates contact the workpiece first, the driving force can be automatically distributed to ensure adaptive clamping while enhancing overall stability through reaction force. Compared with traditional multi-power source clamping devices, it has a more compact structure, lower energy consumption, and simpler operation. With anti-slip rubber pads, it avoids damaging the surface of the workpiece.

[0015] 2. The system adopts a negative pressure dust removal system with interconnected air chambers. Grinding dust is sucked in through the through holes of the workbench and then intercepted by the filter screen and stored in a drawer-type dust collection box. The drawer-type structure facilitates quick cleaning and maintenance, effectively improving the working environment and protecting the health of operators. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4 A dust collection and polishing clamping device includes a workbench 1. The workbench 1 is equipped with a dust collection mechanism and a clamping mechanism. The clamping mechanism includes four L-shaped rods 8 that pass through and are slidably connected to the inner wall of the workbench 1. Clamping plates 9 are fixedly connected to the near ends of the L-shaped rods 8. A sleeve 10 is passed through and rotatably connected to the bottom surface of the workbench 1. A rotating shaft 11 is rotatably connected to the inner wall of the sleeve 10. Two first connecting rods 12 are fixedly connected to the outer wall of the sleeve 10 and the outer wall of the rotating shaft 11. The other ends of the four first connecting rods 12 are rotatably connected to the second connecting rods 13. The other ends of the four second connecting rods 13 are rotatably connected to the lower ends of the four L-shaped rods 8 respectively.

[0024] In this embodiment: Rotating the sleeve 10 causes the two L-shaped rods 8 on the front and rear sides to move synchronously relative to each other via the two first connecting rods 12 and the second connecting rod 13, thereby causing the clamping plates 9 on the front and rear sides to move synchronously relative to each other, clamping the workpiece from the front and rear sides. Rotating the rotating shaft 11 causes the two L-shaped rods 8 on the left and right sides to move synchronously relative to each other via the two first connecting rods 12 and the second connecting rod 13, thereby causing the clamping plates 9 on the left and right sides to move synchronously relative to each other, clamping the workpiece from the left and right sides. This utility model clamps the workpiece from four directions: front, rear, left, and right, making the clamping more secure.

[0025] As a technical optimization of this utility model, the clamping mechanism also includes a first gear 18 that is fixedly connected to the lower end of the outer wall of the sleeve 10 and the lower end of the outer wall of the rotating shaft 11 respectively. Mounting plates 14 are fixedly connected to both the front and rear sides of the lower end face of the worktable 1. Two second slide rods 15 are fixedly connected to the upper and lower sides between the two mounting plates 14. Slide plates 16 are slidably connected to the outer walls of the two second slide rods 15 at the same height. A first spur rack 17 that meshes with the first gear 18 is fixedly connected to the outer walls of the two slide plates 16.

[0026] An electric actuator 19 is installed on the rear end face of the front mounting plate 14. A gantry frame 20 is fixedly connected to the output end of the electric actuator 19. A second gear 21 is rotatably connected to the inner wall of the gantry frame 20. A second rack 22 that meshes with the second gear 21 is fixedly connected to the outer walls of the two sliding plates 16.

[0027] In this embodiment: The electric actuator 19 is activated, causing the portal frame 20 to move backward, which in turn drives the second gear 21 to move backward. The second gear 21 further drives the upper and lower slide plates 16 to slide backward synchronously along the second slide rod 15 via the upper and lower second spur racks 22, thereby driving the upper and lower first spur racks 17 to move backward. The two first spur racks 17 further drive the sleeve 10 and the rotating shaft 11 to rotate counterclockwise synchronously via the upper and lower first gears 18, thereby driving the four L-shaped rods 8 to slide synchronously towards the center position via the four first connecting rods 12 and the four second connecting rods 13, thus driving the four clamping plates 9 to move synchronously towards the workpiece. (The clamping plates 9 on the front and rear sides first contact the workpiece.) (Taking contact as an example) When the clamping plates 9 on the front and rear sides first come into contact with the workpiece, the sleeve 10 stops rotating. The electric push rod 19 continues to push the second gear 21 to move backward, which in turn drives the second gear 21 to roll along the upper second spur rack 22. Then, through the lower second spur rack 22, it drives the lower slide plate 16 to continue sliding backward. The lower slide plate 16 further drives the rotating shaft 11 to continue rotating counterclockwise through the first spur rack 17 and the first gear 18 until the clamping plates 9 on the left and right sides come into contact with and clamp the workpiece. Similarly, the reaction force continues to clamp the workpiece on the front and rear sides until the workpiece is completely fixed. This utility model can clamp the workpiece from four directions with a single power source, and the operation is simple.

[0028] As a technical optimization of this utility model, the dust collection mechanism includes an air cavity 2 fixedly connected to the upper surface of the workbench 1. The upper surface of the workbench 1 has multiple through holes communicating with the air cavity 2. The outer wall of the workbench 1 is provided with a collection box 3 that is connected to the air cavity 2 through a pipe. The inside of the collection box 3 is movably provided with a drawer 4. The lower end of the outer wall of the drawer 4 is provided with a filter screen 5. The outer wall of the workbench 1 is equipped with a suction fan 6 whose air inlet is connected to the collection box 3.

[0029] In this embodiment: the suction fan 6 is started, and the suction fan 6 generates negative pressure in the collection box 3, which in turn generates negative pressure in the air chamber 2 through the pipe, thereby sucking the dust generated by grinding into the collection box 3, and filtering the dust into the drawer 4 through the filter screen 5 for unified treatment.

[0030] As a technical optimization of this utility model, the air inlet of the suction fan 6 is located on the lower side of the filter screen 5.

[0031] In this embodiment, by placing the air inlet of the suction fan 6 on the lower side of the filter screen 5, it is convenient to filter dust.

[0032] As a technical optimization of this utility model, rubber pads are provided on the outer walls of multiple clamping plates 9 that are close to each other.

[0033] In this embodiment, rubber pads are provided on the outer walls of multiple clamping plates 9 that are close to each other to prevent the clamping plates 9 from damaging the workpiece.

[0034] As a technical optimization of this utility model, two first slide rods 7 are fixedly connected to the inner wall of the workbench 1 and the outer wall of the air cavity 2, and four L-shaped rods 8 are slidably connected to eight first slide rods 7 respectively. A sliding groove is provided through the upper end surface of the workbench 1.

[0035] In this embodiment: the first slide bar 7 facilitates the limiting of the L-shaped rod 8, making the L-shaped rod 8 slide stably; and the slide groove is opened on the upper end face of the worktable 1 to facilitate the passage of the L-shaped rod 8.

[0036] As a technical optimization of this utility model, a controller is provided on the outer wall of the workbench 1, and the suction fan 6 and the electric push rod 19 are both electrically connected to the controller.

[0037] In this embodiment, the controller facilitates the normal operation of the suction fan 6 and the electric actuator 19.

[0038] The working principle and usage process of this utility model are as follows: First, the workpiece is placed on the upper surface of the workbench 1 between the four clamping plates 9. Then, the electric actuator 19 is activated, causing the gantry frame 20 to move backward, which in turn drives the second gear 21 to move backward. The second gear 21 further drives the upper and lower slide plates 16 to slide backward synchronously along the second slide rod 15 via the upper and lower second spur racks 22, thereby driving the upper and lower first spur racks 17 to move backward. The two first spur racks 17 further drive the sleeve 10 and the rotating shaft 11 to rotate counterclockwise synchronously via the upper and lower first gears 18, which in turn drives the four L-shaped rods 8 to slide synchronously towards the center position via the four first connecting rods 12 and the four second connecting rods 13, thus driving the four clamping plates 9 to move synchronously towards the workpiece. (The following example shows the clamping plates 9 on the front and rear sides contacting the workpiece first.) When the clamping plates 9 on the front and rear sides contact the workpiece first, the sleeve 10 stops rotating. The electric actuator 19 continues to push the second gear 21 backward, which in turn causes the second gear 21 to roll along the upper second spur rack 22. This, in turn, causes the lower slide plate 16 to continue sliding backward through the lower second spur rack 22. The lower slide plate 16 further drives the rotating shaft 11 to continue rotating counterclockwise through the first spur rack 17 and the first gear 18 until the clamping plates 9 on both sides contact and clamp the workpiece. Similarly, the reaction force continues to clamp the workpiece on both sides until the workpiece is completely fixed. This utility model can clamp the workpiece from four directions with a single power source, making the fixation more reliable and the operation simple. When grinding, the suction fan 6 is started. The suction fan 6 generates negative pressure in the collection box 3, which in turn generates negative pressure in the air chamber 2 through the pipe, thereby sucking the dust generated during grinding into the collection box 3. The dust is then filtered into the drawer 4 through the filter screen 5 to prevent the dust from flying and affecting the health of the operator.

Therefore, they should not be construed as limitations on this utility model.
