Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, and in particular relates to a clamping device for processing spherical structures. Background Art

[0002] Spherical workpieces refer to components or products with a spherical shape. They are more common in industrial production and manufacturing. Their shape is complete and spherical. Spherical workpieces can be made of various materials, such as metal, plastic, glass, ceramic, etc. The properties of these materials determine the use and performance of spherical workpieces. In actual applications, the sizes of spherical workpieces vary greatly, ranging from miniature balls used for internal transmission of precision instruments to large spherical structures, such as the heads of certain storage tanks or containers. Their manufacturing processes are also diverse, and the required precision and surface quality may be achieved through casting, forging, turning, grinding and other processing methods. For example, the ball in a ball bearing is a spherical workpiece with very high precision requirements. It needs to undergo fine grinding to ensure that it can provide low-friction, high-precision support when the bearing is running. Some large spherical workpieces, such as spherical storage tanks in the chemical industry, need to be manufactured using large molds and welding processes.

[0003] The Chinese patent with the announcement number "CN220145320U" discloses a spherical metal product clamping fixture, which includes a mounting base, the bottom end portion of the mounting base is fixedly connected to a support column, the surface of the support column is fixedly connected to a mounting positioning support foot, the top of the mounting base is fixedly connected to a fixed bottom block, the inner side of the fixed bottom block is movably connected to a movable adjustment mechanism, the interior of the fixed bottom block is provided with a fixed guide groove, the outer surface of the movable adjustment mechanism and the inner side of the fixed guide groove are movably connected to a first movable mounting block; this spherical metal product clamping fixture can quickly adjust the movable adjustment mechanism during use through the movable adjustment mechanism, and then can adjust the positions of the first movable mounting block, the movable mounting block, the connecting mounting block and the connecting clamping block, so that the connecting clamping block can clamp and fix the spherical metal product under the action of the arc groove, thereby stably processing the spherical metal product;

[0004] During actual application, although the above-mentioned device can provide auxiliary functions of positioning and clamping for spherical metal workpieces, during the positioning and clamping process, the spherical metal workpiece is in a completely fixed state. If the spherical metal workpiece needs to be flipped and adjusted, especially during the processing process, if all positions on the outer surface of the spherical workpiece need to be processed, then it is obviously necessary to manually remove the spherical workpiece, flip it over and clamp it again before continuing the processing. It can be seen that this operation method is relatively cumbersome and inconvenient as a whole, so it is necessary to improve its design to improve the convenience and efficiency of processing. For example, in the automobile manufacturing industry, for the processing of some spherical parts, if such cumbersome operations are required every time, it will not only increase the labor intensity of the workers, but also extend the production cycle and increase production costs. For example, in the field of precision instrument manufacturing, the processing of tiny spherical metal workpieces requires efficient and convenient clamping and flipping methods, otherwise it is easy to affect the accuracy and quality of the product. Therefore, improvements to the existing devices are imminent. Utility Model Content

[0023] Example

[0024] refer to Figures 1 to 4 The present embodiment is a clamping device for processing a spherical structure, comprising a fixed platform 1, a square groove 2 is formed in the middle of the fixed platform 1, a clamping mechanism 3 is fixedly installed on the rear side of the inner portion of the square groove 2, a mounting frame 4 is fixedly installed on the bottom of the fixed platform 1, a power component 5 is fixedly installed in the middle of the mounting frame 4, a positioning component 6 is fixedly installed in the middle of the front end of the fixed platform 1, and the positioning component 6 is arranged between the clamping ends of the clamping mechanism 3;

[0025] The clamping mechanism 3 includes a guide rail 31, which is fixedly mounted on the rear end of the fixed platform 1. A first motor 32 is fixedly mounted on one end of the guide rail 31. The output end of the first motor 32 passes through the guide rail 31 and is fixedly mounted with a first screw rod 33. The first screw rod 33 is rotatably connected to the inside of the guide rail 31. The threads at both ends of the first screw rod 33 are rotated in opposite directions. Both ends of the first screw rod 33 are threadedly connected to a sliding block 34. The sliding block 34 is slidably connected to the inside of the guide rail 31. A clamping member 35 is fixedly connected to the side of the sliding block 34 close to the square groove 2. The square groove 2 opened in the middle of the fixed platform 1 provides a reasonable installation space for the internal components, making the device structure compact. The setting of the mounting frame 4 provides a stable support for the power component 5. , ensuring stable power output, the guide rail 31 in the clamping mechanism 3 is fixed to the rear end of the fixed platform 1, which enhances the stability of the structure, and the first motor 32 drives the first screw rod 33 to rotate. Since the threads at both ends of the screw rod rotate in opposite directions, the sliding blocks 34 at both ends can be driven to slide toward or away from each other in the guide rail 31, thereby achieving precise clamping action, and the sliding block 34 is tightly connected to the clamping member 35, which can efficiently transmit the clamping force and ensure stable clamping of the spherical structure. The positioning component 6 is located between the clamping ends of the clamping mechanism 3, which helps to improve the accuracy and precision of the clamping. In short, this design makes the entire clamping device stable and reliable in structure, accurate and efficient in function, and can meet the clamping requirements of spherical structure processing.

[0026] refer to Figure 4 The clamping member 35 includes a fixing rod 351, which is fixedly installed on the side of the sliding block 34 close to the square groove 2. A clamping frame 352 is fixedly installed on the side of the fixing rod 351 away from the sliding block 34. The internal top view cross-sectional shape and cross-sectional shape of the clamping frame 352 are both set to be V-shaped. The internal inclined surfaces of the clamping frame 352 are rotatably connected to the balls 353. The external corners of the clamping frame 352 are all set to be arc-shaped. The fixing rod 351 is firmly installed on one side of the sliding block 34, providing a reliable connection for the clamping frame 352. The internal top-view cross-sectional shape and cross-sectional shape of the frame 352 are both designed to be V-shaped, which can adapt well to the spherical structure and fit closely with the curved surface of the spherical workpiece to achieve stable clamping. The ball 353 connected by rotation on the internal inclined surface can not only reduce the friction with the workpiece during clamping, but also help to make it smoother when flipping and adjusting the workpiece. The external edges and corners of the clamping frame 352 are set to be arc-shaped, which effectively avoids possible scratches and damage to the operator or the workpiece, and also optimizes the appearance and safety of the entire clamping device.

[0027] refer to Figure 1-Figure 3The positioning assembly 6 includes a front rail 61, which is fixedly mounted on the middle part of the front end of the fixed platform 1. The interior of the front rail 61 is rotatably connected to the second screw rod 62. The front end of the front rail 61 is fixedly mounted with a second motor 63. The outer surface of the second screw rod 62 is threadedly connected to a sliding block 64. One end of the sliding block 64 close to the square groove 2 is fixedly mounted with a limited suction cup 65. The power assembly 5 includes an electric push rod 51, which is fixedly mounted on the middle part of the mounting frame 4. The top output end of the electric push rod 51 is fixedly mounted with a third motor 52. The output end of the third motor 52 is fixedly mounted with a concave seat 53. A fourth motor 54 is fixedly mounted on one side of the concave seat 53. The output end of the fourth motor 54 passes through the concave seat 53 and is fixedly mounted with a driving wheel 55. The driving wheel 55 is rotatably connected to the concave seat 53. On the inside, in the positioning component 6, the front rail 61 is fixed to the middle of the front end of the fixed table 1, providing stable support for the second screw rod 62 inside, and the second motor 63 drives the second screw rod 62 to rotate, driving the sliding block 64 and the limiting suction cup 65 to move, so as to realize the precise positioning and fixation of the workpiece. In the power component 5, the electric push rod 51 in the middle of the mounting frame 4 provides a stable vertical power output, and the third motor 52 at the top drives the concave seat 53, and the fourth motor 54 on one side drives the wheel 55 to rotate inside the concave seat 53, providing power for the flipping of the spherical workpiece. The overall design is compact, and the various components work together accurately and efficiently. The cooperation of the electric push rod 51 and the motor makes the power output stable and controllable, which can meet the positioning and flipping operations of the workpiece under different processing requirements, and improves the flexibility and efficiency of processing.

[0028] refer to Figure 1-Figure 3 , fixing brackets 7 are fixedly installed on both sides of the bottom of the fixing platform 1, and a mounting plate 8 is fixedly installed on the bottom of the fixing bracket 7. Mounting holes 9 are opened at both ends of the mounting plate 8, and the mounting holes 9 are set as countersunk holes. The fixing bracket 7 provides a stable support for the fixing platform 1, thereby enhancing the stability of the entire device. The mounting holes 9 opened at both ends of the mounting plate 8 provide convenience for the installation and fixation of the device, and setting the mounting holes 9 as countersunk holes can not only make the heads of the mounting bolts sink into the holes, making the installation surface more flat and beautiful, but also prevent the bolt heads from being damaged by external collisions to a certain extent, and at the same time help reduce the interference of the bolt heads on the surrounding environment or operation, thereby ensuring the safety and stability of the device during installation and use.

[0029] Principle and advantages of use: By setting the clamping mechanism 3, during the use of the present device, the workpiece can be placed between the inner sides of the clamping frames 352. At this time, the first motor 32 is started to drive the first screw rod 33 to rotate. Since the threads at both ends of the first screw rod 33 are rotated in opposite directions, the first screw rod 33 can drive the sliding block 34 to slide back and forth on the inner side of the guide rail 31, and the sliding block 34 will drive the two clamping frames 352 to slide back and forth, thereby prompting the clamping frames 352 to clamp the spherical workpiece. It is worth noting that the overall longitudinal and transverse cross-sectional shapes of the clamping frames 352 are both V-shaped, and the internal inclined surface can stably contact the bottom of the arc surface of the spherical workpiece. Through the isosceles inclined surface guidance, it can ensure that the spherical workpiece is stably clamped and positioned. At this time, the spherical workpiece is exactly located in the middle between the inner sides of the clamping frames 352. It can be seen that the adjustable design of the present device cooperates with the V-shaped shape to stably clamp and position spherical workpieces of different sizes, thereby maximizing the stability and adaptability of the overall clamping and positioning of the present device.

[0030] Secondly, by arranging the power component 5 to cooperate with the positioning component 6, during the use of this device, when the spherical workpiece is clamped, the second motor 63 can be started to drive the second screw rod 62 to rotate, and the second screw rod 62 will drive the sliding block 64 to move toward one side of the spherical workpiece. At this time, the sliding block 64 drives the limiting suction cup 65 to fit the outer surface of the spherical workpiece. Through the fit between the limiting suction cup 65 and the spherical workpiece, it can be fixed. At this time, the spherical workpiece can be stably located on the inner side of the clamping frame 352. If the workpiece needs to be flipped and adjusted, the electric push rod 51 can be started to drive the driving wheel 55 to fit the bottom of the spherical workpiece, and then the second motor 63 is started to drive the limiting suction cup 65 to separate from the outer surface of the workpiece, and then the fourth motor 54 is started to drive the driving wheel 55 to rotate, so that the spherical workpiece can be driven to rotate inside the clamping frame 352. When it is necessary to adjust it to the other side, it is only necessary to reposition the workpiece through the positioning component 6, and then start the fourth motor 54 to drive the driving wheel 55 to rotate. The three motors 52 drive the concave seat 53 to rotate, and the driving direction of the driving wheel 55 can be adjusted at this time. In this way, the workpiece can be flexibly flipped in any direction to adapt to the processing requirements to the greatest extent. At the same time, the entire device does not need to be disassembled and manually flipped and adjusted, which can further improve the production and processing efficiency of the device. Moreover, in the process of flipping the spherical workpiece, the ball 353 rolls against the outer surface of the workpiece, which can promote the stable flipping and adjustment of the workpiece, thereby improving the overall ease of use of the device. For example, in the processing scenario of mechanical parts, for spherical workpieces of different specifications, this stable and flexible clamping and flipping design can significantly improve production efficiency and processing accuracy. For example, in the manufacture of electronic equipment, for some miniature spherical components, precise clamping and convenient flipping adjustment functions can ensure the high quality and consistency of the product. In short, these design advantages are of great significance and value in a variety of practical application scenarios.
