Description

Technical Field

[0001] The present application relates to the technical field of workpiece processing equipment, and in particular to a surface grinder. Background Art

[0002] A surface grinder is a type of grinder that mainly uses a grinding wheel to rotate and grind the workpiece so that it can achieve the required flatness.

[0003] A Chinese patent with publication number CN219987059U discloses a surface grinder, including a machine table with a U-shaped bracket welded to the rear outer wall, the bottom inner wall of the machine table is provided with evenly distributed chip suction holes, and two symmetrically distributed clamping components are provided in the machine table, an adjustable grinding mechanism is provided on the U-shaped bracket, and the adjustable grinding mechanism includes a horizontal movement component, a height adjustment component and a grinding component. The suction force generated by the chip suction fan can suck the debris generated during the grinding process through the chip suction holes into the chip suction box for processing, and the debris is filtered and intercepted by the filter net and uniformly collected in the collection frame, which is conducive to the normal progress of the grinding work and saves the subsequent cleaning work.

[0004] In the actual processing process, there are often many irregular workpieces. The clamping components in the related technology are suitable for clamping regular workpieces, but are difficult to adapt to the fixation of irregular workpieces, which affects the processing quality. Utility Model Content

[0005] In order to reduce the adverse effects on machining quality, the present application provides a surface grinder.

[0006] The surface grinder provided in this application adopts the following technical solution:

[0007] A surface grinder comprises a placing plate for placing workpieces, the placing plate is provided with a plurality of vacuum tubes facing the workpieces, the upper ends of the vacuum tubes are provided with baffles, the lower ends of the vacuum tubes arranged along the length direction of the placing plate are connected to control tubes located in the placing plate, and the control tubes are installed with an exhaust pump.

[0008] By adopting the above technical solution, the workpiece is placed on the supporting plate, and the baffle on the vacuum tube located on the lower side of the workpiece is opened. At this time, the vacuum tube on the lower side of the workpiece is connected to the control tube, and the vacuum pump is driven to extract the air in the vacuum tube and the control tube and discharge it through the control tube, so that the workpiece is adsorbed on the vacuum tube, which is convenient for fixing the workpiece, improves the applicability of workpiece fixing, and reduces the adverse effects on processing quality.

[0009] Optionally, the height of the upper end of the vacuum tube is higher than the height of the upper side of the supporting plate, the vacuum tube is slidably connected to the supporting plate, the lower end of the vacuum tube is slidably connected with a connecting tube, the connecting tube is connected to and fixedly connected with the corresponding control tube, and the connecting tube is provided with a reset part for driving the vacuum tube to reset.

[0010] By adopting the above technical solution, when the workpiece is placed on the supporting plate, the weight of the workpiece drives the vacuum tube on the lower side of the workpiece to move toward the connecting tube until the upper end of the vacuum tube is flush with the upper side of the supporting plate, thereby facilitating the support of the workpiece by the supporting plate while improving the stability of the vacuum tube adsorption. When the workpiece is polished, the reset member drives the vacuum tube to reset, facilitating the movement and adsorption of the workpiece again, thereby reducing the adverse effects on the processing quality.

[0011] Optionally, the cross-section of the vacuum tube is set to be square, the baffle is plugged into and slidably connected to the end of the vacuum tube, and a driving component for driving the baffle to open is provided on the connecting tube.

[0012] By adopting the above technical solution, when the driving component drives the baffle to slide and open the vacuum tube, the upper end of the vacuum tube and the side close to the baffle is always blocked by the baffle, reducing the possibility of a gap forming on the upper end of the vacuum tube due to the movement of the baffle, so that the vacuum tube can always be adsorbed on the workpiece, which is convenient for adapting to different workpieces and reducing the adverse effects on processing quality.

[0013] Optionally, the driving assembly includes a first rack fixedly connected to the lower side of the baffle, a first gear rotatably connected to the side wall of the vacuum tube and meshing with the first rack, and a rotating member driving the first gear to rotate is provided on the vacuum tube.

[0014] By adopting the above technical solution, the rotating member drives the first gear to rotate. At this time, the first rack meshing with the first gear drives the baffle to move, thereby opening the vacuum tube, making it easier to adsorb the workpiece on the vacuum tube, improving the stability of the workpiece on the supporting plate, and reducing the adverse effects on the processing quality.

[0015] Optionally, the rotating member includes a belt located in the vacuum tube and having one end mounted on the axis of the first gear, the other end of the belt faces the connecting tube, and the connecting tube is provided with a driving member that drives the first gear to rotate through the belt.

[0016] By adopting the above technical solution, the vacuum tube moves under the drive of the gravity of the workpiece and drives the first gear to rotate through the driving member driving belt, thereby driving the baffle to move through the first rack meshing with the first gear, thereby facilitating the opening of the vacuum tube and adsorbing the workpiece, thereby improving the stability of the workpiece on the supporting plate.

[0017] Optionally, the driving member includes a second gear installed at the end of the belt, the second gear is rotatably connected to the vacuum tube, a second rack is fixedly connected to the side of the connecting tube close to the second gear, and the side of the second gear away from the inside of the vacuum tube passes through the side wall of the vacuum tube and meshes with the second rack.

[0018] By adopting the above technical solution, when the vacuum tube moves toward the direction close to the connecting tube, the second gear moves downward with the vacuum tube and rotates under the drive of the second rack. At this time, the belt drives the first gear to rotate with the second gear, thereby facilitating the driving of the first rack to drive the baffle to move and open the vacuum tube. After the workpiece is polished, the reset member drives the vacuum tube to reset. At this time, the second gear rotates in the opposite direction and drives the baffle to cover the vacuum tube, thereby facilitating the control of the opening and closing of the baffle and improving the fixing efficiency of the workpiece.

[0019] Optionally, the reset member includes a spring having one end fixedly connected to the upper end of the connecting tube, and the other end of the spring fixedly connected to the outer side wall of the vacuum tube.

[0020] By adopting the above technical solution, when the vacuum tube moves toward the connecting tube, the spring is compressed. After the workpiece on the upper side of the vacuum tube is removed, the spring recovers its deformation and pushes the vacuum tube to reset, thereby improving work efficiency.

[0021] Optionally, a limiting plate is fixedly connected to the side wall of the vacuum tube, and a limiting groove adapted to the limiting plate is opened in the supporting plate. When the spring is at its original length, the upper end of the vacuum tube is located outside the supporting plate, and the limiting plate is located at the upper end of the limiting groove.

[0022] By adopting the above technical solution, when the vacuum tube slides on the supporting plate, the limit plate moves in the limit groove. When the spring drives the vacuum tube to reset, the limit plate limits the vacuum tube, reducing the possibility of the vacuum tube moving too far and leaving the supporting plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Place the workpiece on the placing plate, and open the baffle on the vacuum tube on the lower side of the workpiece. At this time, the vacuum tube on the lower side of the workpiece is connected with the control tube, and the vacuum pump is driven to extract the air in the vacuum tube and the control tube and discharge it through the control tube, so that the workpiece is adsorbed on the vacuum tube, which is convenient for fixing the workpiece, improving the applicability of workpiece fixing, and reducing the adverse effects on processing quality;

[0025] 2. When the driving assembly drives the baffle to slide and open the vacuum tube, the upper end of the vacuum tube and the side close to the baffle is always blocked by the baffle, reducing the possibility of a gap in the upper end of the vacuum tube caused by the movement of the baffle, so that the vacuum tube can always be adsorbed on the workpiece, which is convenient for adapting to different workpieces and reducing the adverse effects on processing quality;

[0026] 3. When the vacuum tube moves toward the connecting tube, the second gear moves downward with the vacuum tube and rotates under the drive of the second rack. At this time, the belt drives the first gear to rotate with the second gear, so as to facilitate driving the first rack to drive the baffle to move and open the vacuum tube. After the workpiece is polished, the reset part drives the vacuum tube to reset. At this time, the second gear rotates in the opposite direction and drives the baffle to cover the vacuum tube, so as to facilitate the control of the opening and closing of the baffle and improve the fixation efficiency of the workpiece.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a surface grinder. Figure 1 and Figure 2 A surface grinder comprises a grinder body 1 and a horizontal placing plate 2 installed on the grinder for placing a workpiece, and a plurality of vacuum tubes 3 are arranged vertically and evenly distributed on the placing plate 2. Figure 2 and Figure 3 The cross section of the vacuum tube 3 is set to be square and the upper end height of the vacuum tube 3 is greater than the upper side height of the supporting plate 2. A sliding groove 21 adapted to the vacuum tube 3 is opened in the supporting plate 2. The lower end of the vacuum tube 3 is inserted into the corresponding sliding groove 21 and is slidably connected to the supporting plate 2.

[0033] Reference Figure 2 and Figure 3, a vertical connecting pipe 31 is slidably connected to the outer side of one end of the vacuum tube 3 inserted into the receiving plate 2, and the connecting pipe 31 is inserted into the receiving plate 2. A reset member 32 connected to the corresponding connecting pipe 31 is provided on the outer side of the vacuum tube 3. The reset member 32 includes two vertical springs 321 symmetrically arranged on both sides of the vacuum tube 3, and an annular limiting plate 322 is sleeved and fixedly connected to the outer side of the vacuum tube 3. A limiting groove 22 adapted to the moving trajectory of the limiting ring and connected to the sliding groove 21 is provided on the receiving plate, and the limiting plate 322 is inserted into the limiting groove 22 and slidably connected to the receiving plate. The limiting plate 322 is located on the upper side of the spring 321, and the upper end of the spring 321 is fixedly connected to the limiting plate 322, and the other end is fixedly connected to the upper side of the connecting pipe 31.

[0034] Reference Figure 2 and Figure 3 The upper ends of the vacuum tubes 3 are all slidably connected to a horizontal baffle 33, and the connecting tubes 31 are provided with a driving assembly 4 for controlling the opening or closing of the baffle 33. The lower ends of the connecting tubes 31 located in the same vertical plane parallel to the length direction of the placing plate 2 are all fixedly connected to the same horizontal control tube 34, which is arranged along the length direction of the placing plate 2, and is connected to the corresponding connecting tubes 31. One end of the control tube 34 passes through the placing plate 2 and is installed with an air pump 35.

[0035] When the workpiece is placed on the supporting plate 2, the weight of the workpiece drives the vacuum tube 3 on the lower side of the workpiece to move toward the connecting tube 31 until the upper end of the vacuum tube 3 is flush with the upper side of the supporting plate 2, and the driving component 4 drives the baffle 33 at the upper end of the sliding vacuum tube 3 to open, and the spring 321 is compressed, driving the vacuum pump 35 to extract the air in the vacuum tube 3 and the control tube 34 and discharge it through the control tube 34, thereby adsorbing the workpiece on the vacuum tube 3, which is convenient for fixing the workpiece. When the workpiece is polished, the spring 321 restores its deformation and pushes the vacuum tube 3 to reset through the limit plate 322 until the limit plate 322 moves to the upper end of the limit groove 22, thereby reducing the possibility of the vacuum tube 3 moving too far and leaving the supporting plate 2, which is convenient for moving and adsorbing the workpiece again.

[0036] The side of the upper end of the vacuum tube 3 close to the baffle 33 is always blocked by the baffle 33, reducing the possibility of a gap in the upper end of the vacuum tube 3 caused by the movement of the baffle 33, so that the vacuum tube 3 can always be adsorbed on the workpiece, which is convenient for adapting to different workpieces.

[0037] Reference Figure 2 and Figure 3The driving assembly 4 includes a first rack 41 fixedly connected to the lower side of the baffle 33 and parallel to the length direction of the control tube 34. A vertical first gear 42 is rotatably connected to the inner side wall of one side of the upper end of the vacuum tube 3. The first gear 42 is located below the first rack 41 and meshes with the first rack 41. A rotating member for driving the first gear 42 to rotate is provided on the vacuum tube 3. In the embodiment of the present application, the rotating member is configured as a belt 43 with one end mounted on the axis of the first gear 42, and the other end of the belt 43 faces the connecting tube 31. A driving member 44 for driving the first gear 42 to rotate through the belt 43 is provided on the connecting tube 31.

[0038] Reference Figure 2 and Figure 3 The driving member 44 includes a second gear 441 installed at the end of the belt 43 away from the first gear 42. The second gear 441 is vertical and rotatably connected to the inner wall of the vacuum tube 3. A vertical second rack 442 is fixedly connected to the inner wall of the connecting tube 31 near the second gear 441. The side of the second gear 441 near the second rack 442 passes through the side wall of the vacuum tube 3 and meshes with the second rack 442.

[0039] When the vacuum tube 3 moves toward the connecting tube 31, the second gear 441 moves downward with the vacuum tube 3 and rotates under the drive of the second rack 442. At this time, the belt 43 drives the first gear 42 to rotate with the second gear 441, thereby facilitating the driving of the first rack 41 to drive the baffle 33 to move and open the vacuum tube 3. After the workpiece is polished, the spring 321 drives the vacuum tube 3 to reset. At this time, the second gear 441 rotates in the opposite direction and drives the baffle 33 to cover the vacuum tube 3, thereby completing the opening or closing of the vacuum tube 3.

[0040] The implementation principle of a surface grinder in an embodiment of the present application is as follows: a workpiece is placed on a supporting plate 2, and the weight of the workpiece drives the vacuum tube 3 on the lower side of the workpiece to move toward the connecting tube 31 so that the workpiece is flush with the upper side of the supporting plate 2. The second gear 441 moves with the vacuum tube 3 and rotates under the drive of the second rack 442, thereby driving the first rack 41 through the belt 43 and the first gear 42 to drive the baffle 33 to move and open the vacuum tube 3. The spring 321 is compressed, driving the vacuum pump 35 to work and adsorb the workpiece on the vacuum tube 3 for easy grinding. When the workpiece grinding is completed, the spring 321 restores its deformation and pushes the vacuum tube 3 to reset through the limit plate 322. The second gear 441 rotates in the opposite direction and drives the baffle 33 to cover the vacuum tube 3 until the limit plate 322 moves to the upper end of the limit groove 22, completing the workpiece grinding.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
