Description

Technical Field

[0001] The utility model relates to the technical field of gear ring processing, in particular to a clamping device for gear ring processing. Background Art

[0002] Gear ring processing is a key link in the field of precision machinery manufacturing and is widely used in the automotive, aerospace, wind power, heavy machinery and other industries; the gear ring, as the core component of the gear transmission system, its processing accuracy directly affects the operating efficiency and service life of the entire mechanical equipment; in the manufacturing process of the gear ring, whether it is the forming of the external or internal teeth, it is inseparable from high-precision processing technology, among which the clamping technology of the gear ring is the cornerstone to ensure processing accuracy and processing quality; the clamping of the gear ring refers to the process of firmly fixing the gear ring on the processing equipment through a specific clamping device during the processing, ensuring that the gear ring maintains a stable position and posture throughout the entire processing cycle without being disturbed by external forces; the design and selection of the clamping device is directly related to the processing accuracy, efficiency, safety and cost.

[0003] For example, Chinese patent CN212822769U discloses a semi-automatic universal clamping tool for turning the inner circle of a flywheel gear ring, which includes a three-jaw chuck, a tensioning mechanism, a lever mechanism and a pressure block. The gear ring is clamped and positioned by the claws on the three-jaw chuck, and then the gear ring is pressed by the pressure block, thereby achieving the purpose of clamping the gear ring, solving the problem that the gear ring is easily deformed by clamping the gear ring only by the three-jaw chuck, and effectively reducing the deformation of the gear ring. However, in the process of clamping the gear ring with the above-mentioned universal clamping tool, since vibrations are easily generated during the processing of the gear ring, when the friction force is not enough to resist these vibrations, the gear ring is easily affected and produces a small but significant displacement; although this displacement is small, it is enough to destroy the geometric accuracy of the gear ring, cause tooth shape deviation, and ultimately lead to processing errors, affecting the overall quality and performance of the product.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a clamping device for gear ring processing to overcome the above technical problems existing in the existing related technology.

[0006] To this end, the specific technical solutions adopted by the utility model are as follows:

[0007] A clamping device for processing a gear ring is arranged at the bottom end of the gear ring, comprising a clamping frame arranged at the bottom end of the gear ring, a plurality of clamping grooves are opened at the top end of the clamping frame, a clamping mechanism is inserted at the bottom end of the clamping frame, and the bottom end of the clamping frame is connected to the clamping mechanism through a driving mechanism.

[0008] Furthermore, to ensure the stable clamping of the gear ring during the machining process, under the telescopic action of the electric telescopic rod, the clamping block connected to the electric telescopic rod can move towards the gear ring, and under the connection action of the connecting rod, drive the other clamping blocks to move towards the gear ring until the clamping blocks clamp and fix the gear ring, thereby providing the required stability for the gear ring during the machining process, ensuring the machining accuracy and product quality. The clamping mechanism includes a connecting column inserted in the middle of the clamping frame. The bottom of the connecting column is inserted with a rotating plate, and connecting rods are arranged at the four corners of the top of the rotating plate; clamping blocks are arranged inside the clamping grooves, and one end of the connecting rod away from the rotating plate is connected to the middle of the bottom end of the clamping block; the driving mechanism includes a connecting block arranged at the bottom of a group of clamping blocks and located at the bottom end of the clamping frame, and the cross-section of the connecting block is an inverted U-shaped structure. Fixed columns are inserted at both ends of the connecting block, and electric telescopic rods are arranged at both ends of the fixed columns. Lifting lugs are arranged at both ends of the electric telescopic rods and located at the bottom end of the clamping frame; both ends of the fixed column are connected to the telescopic ends of the electric telescopic rod through two groups of lifting lugs, and the two groups of lifting lugs at the other end of the electric telescopic rod are connected through a connecting column two; a number of clamping grooves are evenly arranged and distributed in a circle at the top of the clamping frame; clamping grooves are provided in the middle of both ends of the clamping block, and an anti-slip surface is arranged on the side of the clamping block close to the gear ring; the cross-section of the connecting rod is a seven-shaped structure, and the four connecting rods are evenly arranged and distributed in a circle under the clamping frame.

[0009] Furthermore, to avoid the gear ring from generating small displacements due to vibrations during the machining process and to avoid damaging the surface of the gear ring, under the dual anti-slip mechanism of the anti-slip convex stripes and the serrated blocks, that is, the serrated blocks can form a bite with the surface of the gear ring to increase the friction force of the contact surface and prevent the gear ring from generating displacements during high-speed machining; at the same time, the unique V-shaped design of the anti-slip convex stripes can not only further increase the friction coefficient to ensure the stable fixation of the gear ring, but also keep the position of the gear ring unchanged even when encountering strong vibrations during the machining process; especially, the side segments of the anti-slip convex stripes are cleverly embedded between the side segments of adjacent anti-slip convex stripes, which not only increases the contact area, improves the clamping stability, but also can disperse the clamping force to avoid damage to the surface of the gear ring caused by excessive local pressure and ensure the machining quality. Serrated blocks are arranged on the top of the anti-slip surface, anti-slip convex stripes are arranged on the bottom of the anti-slip surface, and the cross-section of the anti-slip convex stripes is a V-shaped structure. The openings of adjacent two groups of anti-slip convex stripes face in opposite directions, and the side segments of the anti-slip convex stripes are located inside the side segments of adjacent anti-slip convex stripes.

[0010] The beneficial effects of the present utility model are:

[0011] 1. Through the cooperative setting of the clamping frame, clamping groove, clamping mechanism and driving mechanism, the utility model not only ensures the stability of the clamping of the gear ring during the processing, effectively avoids the occurrence of processing errors, but also, through the finely designed anti-slip and protection mechanism, protects the surface of the gear ring from damage, achieving a significant improvement in the overall quality and performance of the product.

[0012] 2. By setting the cooperative setting of the clamping mechanism and the driving mechanism, under the telescopic action of the electric telescopic rod, the clamping block connected to the electric telescopic rod can move towards the gear ring, and under the connection action of the connecting rod, drive the remaining clamping blocks to move towards the gear ring until the clamping block clamps and fixes the gear ring, thereby providing the required stability for the gear ring during the processing and ensuring the processing accuracy and product quality.

[0013] 3. By setting the anti-slip surface, under the dual anti-slip mechanism of the anti-slip convex stripes and the serrated blocks, that is, the serrated blocks can form a bite with the surface of the gear ring, increasing the friction force of the contact surface and preventing the gear ring from generating displacement during high-speed processing; at the same time, the unique V-shaped design of the anti-slip convex stripes can not only further improve the friction coefficient and ensure the stable fixation of the gear ring, but also keep the position of the gear ring unchanged even when encountering strong vibrations during the processing; especially, the side segments of the anti-slip convex stripes are cleverly embedded between the side segments of the adjacent anti-slip convex stripes, which not only increases the contact area, improves the clamping stability, but also can disperse the clamping force, avoiding damage to the surface of the gear ring caused by excessive local pressure and ensuring the processing quality.

[0023] According to an embodiment of the present utility model, a clamping device for ring gear processing is provided.

[0024] Now, in combination with the drawings and specific embodiments, the present utility model is further described. As Figures 1-5 shown, the clamping device for ring gear processing according to an embodiment of the present utility model is arranged at the bottom end of the ring gear 1, and includes a clamping frame 2 arranged at the bottom end of the ring gear 1. A plurality of clamping grooves 3 are opened at the top end of the clamping frame 2. A clamping mechanism 4 is inserted through the bottom end of the clamping frame 2. The bottom end of the clamping frame 2 is connected to the clamping mechanism 4 through a driving mechanism 5.

[0025] By means of the above technical solution of the present utility model, through the cooperative setting of the clamping frame 2, the clamping groove 3, the clamping mechanism 4 and the driving mechanism 5, the present utility model not only ensures the stability of the clamping of the ring gear 1 during the processing, effectively avoids the occurrence of processing errors, but also protects the surface of the ring gear 1 from damage through the finely designed anti-slip and protection mechanisms, achieving a significant improvement in the overall quality and performance of the product.

[0026] In one embodiment, for the above clamping mechanism 4 and driving mechanism 5, the clamping mechanism 4 includes a connecting column 401 inserted in the middle of the clamping frame 2. A rotating plate 402 is inserted at the bottom of the connecting column 401, and connecting rods 403 are provided at the four corners of the top end of the rotating plate 402; a clamping block 404 is arranged inside the clamping groove 3, and one end of the connecting rod 403 away from the rotating plate 402 is connected to the middle of the bottom end of the clamping block 404; the driving mechanism 5 includes a connecting block 501 arranged at the bottom of a group of clamping blocks 404 and located at the bottom end of the clamping frame 2, and the cross-section of the connecting block 501 is an inverted U-shaped structure. Fixed columns 502 are inserted at both ends of the connecting block 501, and electric telescopic rods 503 are arranged at both ends of the fixed columns 502. Lifting lugs 504 are arranged at both ends of the electric telescopic rods 503 and located at the bottom end of the clamping frame 2; both ends of the fixed column 502 and the telescopic ends of the electric telescopic rod 503 are connected by two groups of lifting lugs 504, and two groups of lifting lugs 504 at the other end of the electric telescopic rod 503 are connected by a connecting column two 505; a number of clamping grooves 3 are evenly arranged and distributed in a circle at the top end of the clamping frame 2; clamping grooves 40401 matching the clamping frame 2 are provided in the middle of both ends of the clamping block 404, and an anti-slip surface 40402 is arranged on one side of the clamping block 404 close to the gear ring 1; the cross-section of the connecting rod 403 is a seven-shaped structure, and the four connecting rods 403 are evenly arranged and distributed in a circle below the clamping frame 2; under the telescopic action of the electric telescopic rod 503, the clamping block 404 connected to the electric telescopic rod 503 can move towards the gear ring 1, and under the connection action of the connecting rod 403, the remaining clamping blocks 404 are driven to move towards the gear ring 1 until the clamping block 404 clamps and fixes the gear ring 1, so as to provide the required stability for the gear ring 1 during the processing, and ensure the processing accuracy and product quality.

[0027] In addition, it should be noted that the above electric telescopic rod 503 is composed of an electric motor, a reduction gear set, a telescopic rod body, a door position sensor, a limit switch, a control unit and a power supply. The working principle of the electric telescopic rod 503 is to convert the rotational motion into a linear driving force through the reduction gear set, and push the pipe segments inside the telescopic rod body to extend or retract in sequence. The composition and working principle of this electric telescopic rod 503 are prior art and will not be elaborated here.

[0028] Working principle of the clamping mechanism 4 and the driving mechanism 5: By starting the electric telescopic rod 503, under the contraction effect of the electric telescopic rod 503, the clamping block 404 connected to the electric telescopic rod 503 moves along the path of the clamping groove 3 towards the direction of the gear ring 1. Under the connection effect of the connecting rod 403, the connecting rod 403 can make an arc motion, and at the same time drive the rotating plate 402 to rotate around the fixed column 502, driving all the connecting rods 403 to make arc motions, thereby driving the remaining clamping blocks 404 to also move along the path of the clamping groove 3 towards the direction of the gear ring 1 until all the clamping blocks 404 surround and clamp the gear ring 1, so as to realize the stability of the gear ring 1 during the processing, and ensure the processing accuracy and product quality.

[0029] In one embodiment, for the above-mentioned anti-slip surface 40402, serrated blocks 4040201 are arranged on the top of the anti-slip surface 40402, anti-slip convex stripes 4040202 are arranged on the bottom of the anti-slip surface 40402, and the cross-section of the anti-slip convex stripes 4040202 is a V-shaped structure. The openings of adjacent two groups of anti-slip convex stripes 4040202 face in opposite directions, and the side segments of the anti-slip convex stripes 4040202 are located inside the side segments of the adjacent anti-slip convex stripes 4040202. It can, under the dual anti-slip mechanism of the anti-slip convex stripes 4040202 and the serrated blocks 4040201, that is, the serrated blocks 4040201 can form a bite with the surface of the gear ring 1 to increase the friction force of the contact surface and prevent the gear ring 1 from generating displacement during high-speed processing. At the same time, the unique V-shaped design of the anti-slip convex stripes 4040202 can not only further improve the friction coefficient to ensure the stable fixation of the gear ring 1, but also keep the position of the gear ring 1 unchanged even when encountering strong vibrations during the processing. Especially, the side segments of the anti-slip convex stripes 4040202 are cleverly embedded between the side segments of the adjacent anti-slip convex stripes 4040202, which not only increases the contact area, improves the clamping stability, but also can disperse the clamping force, avoid local excessive pressure from damaging the surface of the gear ring 1, and ensure the processing quality.

[0030] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0031] During actual application, the operator places the gear ring 1 at the middle of the top of the clamping frame 2, and clamps the gear ring 1 by starting the clamping mechanism 4 and the driving mechanism 5 to ensure the stable clamping of the gear ring 1 during the processing. At the same time, the anti-slip surface 40402 is used to avoid the micro-displacement of the gear ring 1 caused by vibrations during the processing and avoid damaging the surface of the gear ring 1.

[0032] In summary, by means of the above technical solution of the present utility model, through the cooperative setting of the clamping frame 2, the clamping groove 3, the clamping mechanism 4 and the driving mechanism 5, not only the stability of the clamping of the gear ring 1 during the processing is ensured, effectively avoiding the occurrence of processing errors, but also, through the finely designed anti-slip and protection mechanisms, the surface of the gear ring is protected from damage, achieving a significant improvement in the overall quality and performance of the product; through the cooperative setting of the clamping mechanism 4 and the driving mechanism 5, under the telescopic action of the electric telescopic rod 503, the clamping block 404 connected to the electric telescopic rod 503 can move towards the gear ring 1, and under the connection action of the connecting rod 403, drive the remaining clamping blocks 404 to move towards the gear ring 1 until the clamping blocks 404 clamp and fix the gear ring 1, thereby providing the required stability for the gear ring 1 during the processing and ensuring the processing accuracy and product quality; by setting the anti-slip surface 40402, under the dual anti-slip mechanism of the anti-slip convex stripes 4040202 and the serrated blocks 4040201, that is, the serrated blocks 4040201 can form an engagement with the surface of the gear ring 1 to increase the friction force of the contact surface and prevent the gear ring 1 from generating displacement during high-speed processing; at the same time, the unique V-shaped design of the anti-slip convex stripes 4040202 can not only further increase the friction coefficient to ensure the stable fixation of the gear ring 1, but also keep the position of the gear ring 1 unchanged even when encountering strong vibrations during the processing; especially, the side segments of the anti-slip convex stripes 4040202 are ingeniously embedded between the side segments of the adjacent anti-slip convex stripes 4040202, which not only increases the contact area, improves the clamping stability, but also can disperse the clamping force and avoid damage to the surface of the gear ring 1 caused by excessive local pressure, ensuring the processing quality.
