Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a clamping device for a grinding machine. Background Technology

[0002] A grinding machine is a mechanical device used to grind and finish the surface of a workpiece to achieve a smooth and flat surface. The clamping device is an important component of the grinding machine. Its main function is to stably clamp the workpiece during the grinding process to ensure the accuracy and safety of the process.

[0003] In the grinding process, stable clamping of the workpiece is a key link to ensure processing accuracy and operational safety. Existing grinding machine clamping equipment has many shortcomings in practical applications. Most clamping equipment has a relatively simple clamping structure, which is difficult to adapt to workpieces of different shapes and sizes. In particular, for plate-shaped workpieces with arc or irregular contours, problems such as unstable clamping and positioning deviation are prone to occur, affecting the accuracy of grinding. Therefore, this application proposes a clamping device for grinding machines. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a clamping device for a grinding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a clamping device for a grinding machine, comprising a main body, configured as a vertical box structure, a processing area is provided on the left side of the front of the upper half of the main body, a storage cavity is provided on the front side of the lower half of the main body, and an installation port communicating with the storage cavity is provided at the bottom of the processing area. The storage mechanism is installed in the mounting opening at the bottom of the processing area; The material collection hood is installed at the mounting opening on the top of the storage cavity; The collection box is placed inside the storage cavity and below the collection hood. Rollers are installed at the four corners of the bottom of the collection box. Two slots extending to the front of the main body are opened at the bottom of the storage cavity, and the four rollers are located in the corresponding slots. The cabinet door has two hinges that are symmetrically mounted on the opening of the storage compartment; The control panel is mounted on the front of the main body and located on the right side of the processing area.

[0006] Furthermore, the storage mechanism includes a base plate, a top plate, a lifting plate, two sets of clamping components, and an adjusting component. The base plate is installed in the mounting opening, and a lower opening is provided in the center of the base plate. The lifting plate is located in the lower opening. The top plate is located directly above the base plate, and an upper opening is provided in the center of the top plate. The upper opening and the lower opening are the same size and aligned vertically. Support blocks are fixedly installed between the centers of both ends of the top plate and the base plate. The two sets of clamping components are diagonally distributed between the base plate and the top plate. The adjusting component is installed at the bottom of the base plate and the lifting plate.

[0007] Furthermore, the clamping assembly includes clamping plates and motors. The motors in the two clamping assemblies are installed diagonally at two corners on the top of the top plate. The clamping plates in the two clamping assemblies are installed diagonally between the top plate and the bottom plate. The output end of the motor passes through the top plate and is fixedly connected to the top of one end of the clamping plate. The end of the clamping plate away from the motor is set in an arc shape, and the diameter of the arc end of the clamping plate is smaller than the diameter of the upper opening. Support columns are fixedly installed between the two corners of the top plate and the bottom plate away from the motor.

[0008] Furthermore, two grooves are formed on the inner wall of the arc end of the clamping plate, and an extrusion block is fixedly installed in each of the two grooves. Two first hydraulic rods are fixedly installed on the outer side of the arc end of the clamping plate, and the telescopic ends of the two first hydraulic rods extend into the corresponding grooves and are fixedly connected to the extrusion blocks.

[0009] Furthermore, the adjustment assembly includes a fixed frame, second hydraulic rods, fixed blocks, and a horizontal plate. The fixed frame is fixedly installed at the bottom of the base plate in a U-shape, and the horizontal part of the fixed frame is located directly below the lower opening. The two ends of the bottom of the horizontal part of the fixed frame are fixedly installed with second hydraulic rods. The telescopic ends of the two second hydraulic rods pass through the fixed frame, and fixed blocks are fixedly installed at the telescopic ends of the two second hydraulic rods. The horizontal plate is fixedly installed at the bottom of the lifting plate, and the length of the horizontal plate is greater than the diameter of the lifting plate. A rod shaft is provided at both ends of the horizontal plate. The horizontal plate is located between the two fixed blocks, and the rod shafts at both ends of the horizontal plate are rotatably inserted into the sides of the two fixed blocks.

[0010] Furthermore, connecting plates are fixedly installed on both sides of the center of the horizontal section of the fixed frame. Springs are fixedly connected to the top of the two connecting plates at the ends away from the fixed frame. The tops of the two springs are fixedly connected to the bottom of the lifting plate, and the two springs are vertically and symmetrically distributed on both sides of the horizontal plate.

[0011] Furthermore, a top rod is fixedly installed on the top of one of the connecting plates, and the height of the top rod is half the distance between the connecting plate and the bottom plate.

[0012] The beneficial effects of this utility model are: With two sets of diagonally distributed clamping components and the design of the arc end of the clamping plate, it can adapt to plate-shaped workpieces with arc or irregular contours. At the same time, the extrusion block on the inner side of the clamping plate can be flexibly adjusted through the first hydraulic rod, which can not only ensure that the workpiece does not shift during processing, but also further increase the stability of workpiece clamping. It effectively solves the problems of unstable clamping and positioning deviation of traditional equipment for irregular workpieces, and significantly improves the processing accuracy.

[0013] The adjustment assembly, through the cooperation of the second hydraulic rod, the cross plate, and the spring, can drive the lifting plate to move up and down. When the lifting plate descends, it will move out of the lower opening at the top of the base plate. As the lifting plate continues to descend, it will contact the top rod and be pushed by the top rod, causing the lifting plate to tilt. This allows the debris generated during grinding on the lifting plate to slide down, thus preventing the debris from affecting the placement of the workpiece and also cleaning up the debris.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1-9 This utility model provides a technical solution: a clamping device for a grinding machine, including a main body 11, which is a vertical box structure. A processing area 12 is provided on the left side of the front of the upper half of the main body 11, and a storage cavity 14 is provided on the front of the lower half of the main body 11. An installation port 15 communicating with the storage cavity 14 is provided at the bottom of the processing area 12. A storage mechanism 2 is installed in the installation port 15 at the bottom of the processing area 12. A material collection hood 16 is installed at the installation port 15 at the top of the storage cavity 14. A collection box 17 is provided inside the storage cavity 14 and below the material collection hood 16. The four corners at the bottom of the collection box 17... All are equipped with rollers 171. The bottom of the storage cavity 14 has two slots 18 extending to the front of the main body 11. The four rollers 171 are located in the corresponding slots 18. The door 19 is symmetrically hinged at the opening of the storage cavity 14. The control panel 13 is set on the front of the main body 11 and on the right side of the processing area 12. The collection box 17 is quickly pulled out and cleaned by the rollers 171 cooperating with the slots 18, which solves the problem of inconvenient debris collection of traditional equipment. The door 19 design protects the internal structure of the storage cavity 14 and improves the safety of operation. The centralized setting of the control panel 13 simplifies the equipment operation process.

[0017] like Figure 4 and Figure 7As shown, the storage mechanism 2 includes a base plate 21, a top plate 22, a lifting plate 25, two sets of clamping components, and an adjusting component 4. The base plate 21 is installed in the mounting opening 15, and a lower opening 211 is provided at the center of the base plate 21. The lifting plate 25 is located in the lower opening 211. The top plate 22 is located directly above the base plate 21, and an upper opening 221 is provided at the center of the top plate 22. The upper opening 221 and the lower opening 211 are the same size and aligned vertically. Support blocks 23 are fixedly installed between the centers of both ends of the top plate 22 and the base plate 21. The two sets of clamping components are diagonally distributed on the base plate 21. Between plate 21 and top plate 22, adjustment component 4 is installed at the bottom of bottom plate 21 and lifting plate 25. The placement mechanism 2, through the cooperation of bottom plate 21, top plate 22 and lifting plate 25, combined with the upper opening 221 and lower opening 211 aligned vertically, provides a channel for debris to fall, taking into account both workpiece placement stability and debris collection efficiency. Two sets of diagonally distributed clamping components can adapt to workpieces of different shapes. Adjustment component 4 can adjust the lifting plate 25 vertically. By lowering the height and tilting the angle of the lifting plate 25, the debris accumulated on the lifting plate 25 can be cleaned.

[0018] like Figure 6 and Figure 9 As shown, the clamping assembly includes a clamping plate 31 and a motor 32. The motors 32 in the two clamping assemblies are installed diagonally at the two corners of the top plate 22. The clamping plates 31 in the two clamping assemblies are installed diagonally between the top plate 22 and the bottom plate 21. The output end of the motor 32 passes through the top plate 22 and is fixedly connected to the top of one end of the clamping plate 31. The end of the clamping plate 31 away from the motor 32 is set as an arc shape, and the diameter of the arc end of the clamping plate 31 is smaller than the diameter of the upper opening 221. Support columns 24 are fixedly installed between the two corners of the top plate 22 and the bottom plate 21 away from the motor 32. The clamping assembly uses a diagonal motor 32 to drive the clamping plate 31. The arc end of the clamping plate 31 is designed to adapt to arc-shaped or irregular workpieces, avoiding the problem of unstable clamping of irregular workpieces. The support columns 24 further strengthen the connection between the top plate 22 and the bottom plate 21, improve the overall structural strength of the placement mechanism 2, ensure accurate workpiece positioning during processing, and reduce processing deviations caused by vibration.

[0019] like Figure 6 and Figure 9As shown, two grooves 311 are formed on the inner wall of the arc end of the clamping plate 31. An extrusion block 34 is fixedly installed in each of the two grooves 311. Two first hydraulic rods 33 are fixedly installed on the outer side of the arc end of the clamping plate 31. The telescopic ends of the two first hydraulic rods 33 extend into the corresponding grooves 311 and are fixedly connected to the extrusion block 34. The thickness of the clamping plate 31 matches the distance between the top plate 22 and the bottom plate 21 to ensure that the workpiece is subjected to balanced force during clamping. The extrusion block 34 in the groove 311 can adjust its telescopic length through the first hydraulic rod 33. The clamping force can be flexibly controlled according to the shape of the workpiece, which can not only prevent the workpiece from slipping, but also further improve the stability of clamping irregular workpieces.

[0020] like Figure 7 and Figure 8 As shown, the adjusting assembly 4 includes a fixed frame 41, second hydraulic rods 42, fixed blocks 43, and a horizontal plate 44. The fixed frame 41 is fixedly installed in a U-shape at the bottom of the base plate 21, and the horizontal part of the fixed frame 41 is located directly below the lower opening 211. The two ends of the bottom of the horizontal part of the fixed frame 41 are fixedly installed with second hydraulic rods 42. The telescopic ends of the two second hydraulic rods 42 pass through the fixed frame 41, and fixed blocks 43 are fixedly installed at the telescopic ends of the two second hydraulic rods 42. The horizontal plate 44 is fixedly installed at the bottom of the lifting plate 25. The horizontal plate 44 is longer than the diameter of the lifting plate 25. Both ends of the horizontal plate 44 are provided with rod shafts 441. The horizontal plate 44 is located between two fixed blocks 43, and the rod shafts 441 at both ends of the horizontal plate 44 are rotatably inserted into the sides of the two fixed blocks 43. The adjusting component 4 drives the fixed blocks 43 through the second hydraulic rod 42, thereby driving the horizontal plate 44 and the lifting plate 25 to achieve height adjustment. The rotatable connection design between the horizontal plate 44 and the fixed blocks 43 allows the lifting plate 25 to tilt slightly, allowing debris on the lifting plate 25 to slide down.

[0021] like Figure 7 and Figure 8 As shown, connecting plates 45 are fixedly installed on both sides of the center of the horizontal part of the fixed frame 41. Springs 46 are fixedly connected to the top of the two connecting plates 45 at the end away from the fixed frame 41. The top of the two springs 46 are fixedly connected to the bottom of the lifting plate 25. The two springs 46 are vertically and symmetrically distributed on both sides of the horizontal plate 44. The springs 46 provide elastic support for the lifting plate 25, so that the lifting plate 25 can be in a nearly horizontal state.

[0022] like Figure 7 and Figure 8As shown, a top rod 47 is fixedly installed on the top of one of the connecting plates 45. The height of the top rod 47 is half the distance between the connecting plate 45 and the bottom plate 21. During the process of the lifting plate 25 descending, the top rod 47 can lift one end of the lifting plate 25 to make it tilt, so that the debris on the lifting plate 25 can slide down smoothly and fall into the collection box 17 below through the collection hood 16, thereby realizing the cleaning and collection of debris.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
