Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a high-precision housing manufacturing device. Background Technology

[0002] Cylindrical shells are widely used in various fields due to their simple structure and excellent load-bearing performance, especially excelling in strength, stability, and space utilization. During manufacturing, cylindrical shells typically require machining holes or other structures, primarily to meet assembly, connection, operation, or inspection functions. To ensure machining accuracy and improve operational safety and production efficiency, fixtures are usually used. However, most commonly used circular fixtures have rigid, fixed gripping jaws with limited contact points with the cylindrical shell, typically only 3-4 discrete contact points. Because the clamping force transmission path is singular, the force distribution is concentrated only in the jaw contact area, making it difficult to diffuse evenly along the circumference, easily leading to localized stress concentration. This causes excessive stress on certain parts of the cylindrical shell, potentially inducing plastic deformation or microcracks, ultimately affecting the roundness and dimensional accuracy of the shell. Utility Model Content

[0003] The purpose of this invention is to address the problem that existing circular clamps have rigidly fixed grippers with few contact points and single force transmission, which easily leads to local stress concentration, thereby causing plastic deformation or cracks in the cylindrical shell and affecting roundness and dimensional accuracy. The invention proposes a high-precision shell manufacturing device.

[0004] The technical solution of this utility model is as follows: a high-precision housing manufacturing device, including a base and a cylindrical housing, and further including: a plurality of support blocks arranged in a circumferential array, located on the top of the base, the support blocks having an inner frame inside, the inner frame having a locking mechanism for fixing the cylindrical housing after the support blocks are opened; and a driving mechanism, located in the middle of the inner frame and the base, to open and close the locking mechanism.

[0005] Optionally, the locking mechanism includes a locking block inserted between the support blocks. The inner frame has multiple first sliding grooves corresponding to the support blocks. A pair of first springs are fixedly connected inside each of the first sliding grooves. A center block is fixedly connected to the inner wall of each support block. The end of each first spring away from the first sliding groove is fixedly connected to the center block. The inner frame also has multiple second sliding grooves corresponding to the locking blocks. A second spring is fixedly connected inside each of the second sliding grooves. The end of each second spring away from the second sliding groove is fixedly connected to the corresponding locking block.

[0006] Optionally, the driving mechanism includes a cylinder fixedly connected to the upper surface of the base. The piston rod of the cylinder is fixedly connected to a U-shaped locking block. The end of the U-shaped locking block away from the cylinder is fixedly connected to a sleeve that inserts into the middle of the locking block. One end of the central block is provided with a locking groove for the sleeve to be inserted. The upper surface of the base is fixedly connected to a U-shaped frame that holds the U-shaped locking block. The upper surface of the U-shaped frame is fixedly connected to a telescopic rod that moves through the sleeve and is fixedly connected to the inner frame.

[0007] Optionally, the end of the sleeve away from the U-shaped locking block is provided with a tapered abutment.

[0008] Optionally, a first anti-slip pad is fixedly connected to the outer wall of the support block, and a second anti-slip pad is fixedly connected to the outer wall of the locking block.

[0009] Optionally, the outer walls of the support blocks are all fixedly connected with support strips for supporting the cylindrical shell.

[0010] Optionally, one end of the locking block inserted between the support blocks is provided with an inclined surface, and the locking block inserted into the support block forms a circular structure with the same size as the inner diameter of the cylindrical shell.

[0024] Example

[0025] like Figures 1 to 4 As shown, this utility model proposes a high-precision housing manufacturing device, including a base 1 and a cylindrical housing 2. The cylindrical housing 2 is the object to be processed by the device and is clamped and fixed by support blocks 3 for high-precision processing. The top of the base 1 is provided with multiple support blocks 3 arranged in a circumferential array. These support blocks 3 are spread out under the action of locking blocks 45, and their outer walls contact the inner wall of the cylindrical housing 2, achieving clamping and fixing of the housing. A first anti-slip pad 34 is fixedly connected to the outer wall of the support block 3, enhancing the friction with the inner wall of the cylindrical housing 2, preventing slippage, and also providing a cushioning effect. A second anti-slip pad 46 is fixedly connected to the outer wall of the locking blocks 45, enhancing the friction with the inner wall of the cylindrical housing 2, assisting in fixing the housing, and also providing a cushioning effect. Each support block 3 has a fixed support strip 33 on its outer wall to support the cylindrical shell 2. The support strip 33 is fixed to the outer wall of the support block 3 to support the cylindrical shell 2 and make it more stable. The support block 3 has an inner frame 4 inside it. The inner frame 4 is located inside the support block 3 and has a first sliding groove 41 and a second sliding groove 43 to provide installation and movement space for the first spring 42 and the second spring 44. The inner frame 4 is provided with a locking mechanism to fix the cylindrical shell 2 after the support block 3 is opened. The middle of the inner frame 4 and the base 1 is provided with a drive mechanism to open and close the locking mechanism.

[0026] Among them, such as Figures 1 to 4As shown, the locking mechanism includes a locking block 45 inserted between the support blocks 3. The locking block 45 is inserted between the support blocks 3 and, under the push of the conical abutment 51, opens the support blocks 3. The second anti-slip pad 46 on its outer wall enhances the fit with the shell. The ends of the locking blocks 45 inserted between the support blocks 3 are all inclined, and the locking blocks 45 form a circular structure with the same inner diameter as the cylindrical shell 2. The inner frame 4 has multiple first sliding grooves 41 corresponding to the support blocks 3. The first sliding grooves 41 are formed on the inner frame 4, and first springs 42 are fixed inside, providing guidance for the extension and retraction of the first springs 42. A pair of first springs 42 are fixedly connected inside each first sliding groove 41. One end of each first spring 42 is fixed inside the first sliding groove 41, and the other end is fixed to the center block 31. They extend and retract when the support blocks 3 move, providing a restoring force and adaptive elasticity. A center block 31 is fixedly connected to the inner wall of each support block 3. The center block 31 is fixed to the inner wall of the support block 3 and connected to the first spring 42. The locking groove 32 on the center block 3 allows the sleeve 5 to be inserted and participate in the locking mechanism. The end of the first spring 42 away from the first slide groove 41 is fixedly connected to the center block 31. The inner frame 4 also has multiple second slide grooves 43 corresponding to the locking blocks 45. The second slide grooves 43 are formed on the inner frame 4, and the second springs 44 are fixed inside them, providing guidance for the extension and retraction of the second springs 44. The second springs 44 are fixedly connected inside each of the second slide grooves 43. One end of the second spring 44 is fixed inside the second slide groove 43, and the other end is fixed to the locking block 45. It extends and retracts when the locking block 45 moves, providing a restoring force and adaptive elastic force. The end of the second spring 44 away from the second slide groove 43 is fixedly connected to the corresponding locking block 45.

[0027] In addition, such as Figures 1 to 4As shown, the driving mechanism includes a cylinder 11 fixedly connected to the upper surface of the base 1. The cylinder 11 provides driving force, and its piston rod can drive the U-shaped locking block 52 and the sleeve 5 to move, realizing clamping or releasing actions. The piston rod of the cylinder 11 is fixedly connected to the U-shaped locking block 52. The U-shaped locking block 52 connects the piston rod of the cylinder 11 and the sleeve 5. Under the drive of the cylinder 11, it drives the sleeve 5 to move, and at the same time, it is locked and limited by the U-shaped frame 12. The end of the U-shaped locking block 52 away from the cylinder 11 is fixedly connected to the sleeve 5 inserted into the middle of the locking block 45. One end of the sleeve 5 is fixed to the U-shaped locking block 52, and the other end is provided with a conical abutment 51. Under the drive of the cylinder 11, it moves and pushes the locking block 45 through the conical abutment 51, and can be locked into the locking groove 32. A tapered abutment 51 is provided at the end of the sleeve 5 away from the U-shaped locking block 52. The tapered abutment 51 is located at the end of the sleeve 5 away from the U-shaped locking block 52. The tapered structure pushes the locking block 45 to move between the support block 3, thus opening the support block 3 and the locking block 45. A locking groove 32 is provided at one end of the center block 31 for the sleeve 5 to be inserted, thereby locking the support block 3 in the opened state. A U-shaped frame 12 is fixedly connected to the upper surface of the base 1 to hold the U-shaped locking block 52. The U-shaped frame 12 holds the U-shaped locking block 52 and limits its movement. At the same time, the structure connected to the upper surface passes through the sleeve 5 and is fixed to the inner frame 4, playing an auxiliary fixing role. The upper surface of the U-shaped frame 12 is fixedly connected to a telescopic rod 47 that is movable through the sleeve 5 and then fixedly connected to the inner frame 4. The telescopic rod 47 is used to fix the inner frame 4 on the U-shaped frame 12 to ensure that the inner frame 4 is stably supported under normal conditions.

[0028] In this embodiment, when using a high-precision housing manufacturing device, the cylindrical housing 2 is placed on the support strip 33 of the support block 3. Then, the cylinder 11 is activated, and the piston rod of the cylinder 11 drives the U-shaped locking block 52 and the sleeve 5 to move along the telescopic rod 47 towards the inner frame 4. At this time, the conical abutment 51 at the front end of the sleeve 5 is inserted into the middle of the locking block 45. As the conical abutment 51 advances, it pushes the locking block 45 to move between the support blocks 3. The inclined surface of the locking block 45 squeezes the support block 3 to make it open outward. At the same time, the first spring 42 and the second spring 44 are stretched and stored. The first anti-slip pad 34 on the outer wall of the support block 3 is in contact with the inner wall of the cylindrical housing 2, and multiple support blocks 3 arranged in a circumferential array form a circular structure matching the inner diameter of the cylindrical housing 2 under the action of the locking block 45, so as to achieve uniform clamping.

[0029] When the locking groove 32 on the center block 31 engages with the sleeve 5, the locking mechanism is fixed, and the U-shaped frame 12 limits the U-shaped locking block 52 to ensure stable clamping. After machining, the reverse-start cylinder 11 retracts the conical abutment 51, the first spring 42 and the second spring 44 return to their original positions, pulling the support block 3 and the locking block 45 back to their original positions. The support block 3 disengages from the cylindrical shell 2, allowing the shell to be removed. The entire process, through the cooperation of the elastic element and the conical structure, achieves adaptive and uniform clamping of the cylindrical shell, avoiding local stress concentration and ensuring machining accuracy.
