Description

Technical Field

[0001] This utility model relates to the field of tooling, and in particular to a tooling for clamping and heat-treating workpieces with low deformation. Background Technology

[0002] Workpiece clamping heat treatment fixtures are fixtures that clamp and position metal workpieces during heat treatment, allowing the workpieces to undergo heat treatment in a fixed position. They are widely used in various metal workpiece processing applications.

[0003] However, when using tooling, in order to suppress the deformation of the workpiece during the heat treatment process, it is usually necessary to use special tooling fixtures to clamp and fix it. At present, the industry generally uses rigid fixtures. Although these fixtures have a simple structure, they have many drawbacks in practical applications: First, rigid fixtures are prone to generating excessive concentrated stress in the local area of ​​the workpiece when clamping. They may also undergo thermal deformation at high temperatures, which will aggravate the deformation of the workpiece, causing the workpiece to have out-of-tolerance deformation after heat treatment, making it difficult to guarantee dimensional accuracy, and even causing the product to be scrapped. Second, traditional fixtures are usually custom-made for specific workpieces and have poor versatility. When the size or shape of the workpiece changes, it is often necessary to replace the entire set of fixtures, which is cumbersome, time-consuming and labor-intensive, seriously affecting production efficiency and equipment utilization. Furthermore, most existing fixtures have a single function, which can only achieve fixed clamping and cannot adjust the angle of the workpiece during the heat treatment process. This may lead to uneven heating of the workpiece in the furnace and affect the stability of the heat treatment quality. Utility Model Content

[0004] The main purpose of this utility model is to provide a workpiece clamping and heat treatment fixture with low deformation, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A low-deformation workpiece clamping heat treatment fixture includes a mounting base and screw mounting blocks. The screw mounting blocks are integrally formed on the front and rear ends of the mounting base. Positive and negative screws are movably mounted on the inner side of the mounting base. A first slider and a second slider are movably mounted on the upper end of the mounting base, with the first slider located on one side of the second slider. Threaded blocks are integrally formed on the lower ends of both the first and second sliders. A first rotating head is movably mounted on one side of the first slider, and a second rotating head is movably mounted on one side of the second slider. A strap structure is provided between the first rotating head and the second rotating head.

[0007] As a further embodiment of this utility model, the first slider and the second slider are arranged symmetrically, and the first slider and the second slider are located above the positive and negative screws.

[0008] As a further embodiment of this utility model, the threaded block is located inside the mounting base, and the positive and negative screws pass through the threaded block and are threadedly connected to it. A screw drive head is welded to one end of the positive and negative screws.

[0009] As a further embodiment of this utility model, a turntable is movably mounted on the other side of the first slider, and an adjustment drive head is fixedly mounted on one side of the turntable. One end of the adjustment drive head passes through the turntable and the first slider and is fixedly connected to the first rotating head.

[0010] As a further embodiment of this utility model, the bandage structure includes a T-shaped mounting block, a screw plate, clamping bandages, and anti-slip protrusions. The two T-shaped mounting blocks are respectively installed in the slots of the first rotating head and the second rotating head. The screw plate is welded to the outside of the T-shaped mounting block. The two clamping bandages are fixedly installed between the two T-shaped mounting blocks. The anti-slip protrusions are integrally formed on the adjacent surfaces of the two clamping bandages.

[0011] As a further embodiment of this utility model, the T-shaped mounting block is inserted into the slots of the first rotating head and the second rotating head from the front and rear, and the screws on the screw plate position the T-shaped mounting block within the slots of the first rotating head and the second rotating head, with the clamping bandage located between the first rotating head and the second rotating head.

[0012] Compared with the prior art, the present invention has the following advantages: by setting the bandage structure, the elastic properties of the clamping bandage are utilized to provide uniform pressure when clamping the workpiece, avoiding local stress concentration and deformation caused by traditional rigid clamps, reducing the deformation caused by clamping, and is particularly suitable for thin-walled or easily deformable metal workpieces, ensuring higher dimensional accuracy after heat treatment.

[0013] The tooling adopts a modular design. The T-shaped mounting block can be inserted into the slots of the first and second rotating heads and fixed by screw plates, enabling quick replacement. Different sizes of clamping straps can be replaced to clamp workpieces of different sizes, improving the versatility of the tooling and reducing downtime.

[0014] By adjusting the drive head to drive the first rotating head, the second rotating head is driven to rotate synchronously, thereby causing the clamped workpiece to rotate. The workpiece can be adjusted 360° in the clamped state, which facilitates the workpiece to be heated in multiple directions in the heat treatment furnace and improves the uniformity of processing.

[0020] 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.

[0021] like Figures 1-4 As shown, please refer to the heat treatment fixture for clamping workpieces with low deformation. Figures 1-4 The system includes a mounting base 1 and a screw mounting block 2. The screw mounting block 2 is integrally formed at the front and rear ends of the mounting base 1. A positive and negative screw 3 is movably mounted on the inner side of the mounting base 1. A first slider 5 and a second slider 6 are movably mounted on the upper end of the mounting base 1, with the first slider 5 located on one side of the second slider 6. Threaded blocks 7 are integrally formed on the lower ends of both the first slider 5 and the second slider 6. A first rotating head 8 is movably mounted on one side of the first slider 5, and a second rotating head 11 is movably mounted on one side of the second slider 6. A bandage structure 12 is provided between the first rotating head 8 and the second rotating head 11.

[0022] Please refer to this carefully. Figure 1 and Figure 2 The first slider 5 and the second slider 6 are arranged symmetrically, and the first slider 5 and the second slider 6 are located above the positive and negative screws 3.

[0023] Please refer to this carefully. Figure 1 and Figure 2 The threaded block 7 is located inside the mounting base 1. The positive and negative screws 3 pass through the threaded block 7 and are threadedly connected to it. One end of the positive and negative screws 3 is welded with a screw drive head 4.

[0024] Specifically, when the positive and negative screws 3 are rotated, they are connected to the two threaded blocks 7 by the positive and negative threads, which causes the two threaded blocks 7 to move in opposite directions, thereby causing the first slider 5 and the second slider 6 to move in opposite directions.

[0025] Please refer to this carefully. Figures 1-3A turntable 9 is movably mounted on the other side of the first slider 5. An adjustment drive head 10 is fixedly mounted on one side of the turntable 9. One end of the adjustment drive head 10 passes through the turntable 9 and the first slider 5 and is fixedly connected to the first rotating head 8.

[0026] Specifically, when the drive head 10 rotates, it drives the first rotating head 8 to rotate. At the same time, the first rotating head 8 also drives the second rotating head 11 to rotate through the bandage structure 12, thereby adjusting the angle of the workpiece fixed in the bandage structure 12.

[0027] Please refer to this carefully. Figures 2-4 The bandage structure 12 includes a T-shaped mounting block 13, a screw plate 14, a clamping bandage 15, and an anti-slip protrusion 16. The two T-shaped mounting blocks 13 are respectively installed in the slots of the first rotating head 8 and the second rotating head 11. The screw plate 14 is welded to the outside of the T-shaped mounting block 13. The two clamping bandages 15 are fixedly installed between the two T-shaped mounting blocks 13. The anti-slip protrusion 16 is integrally formed on the adjacent surfaces of the two clamping bandages 15.

[0028] Please refer to this carefully. Figures 2-4 The T-shaped mounting block 13 is inserted into the slots of the first rotating head 8 and the second rotating head 11 from the front and rear to position the T-shaped mounting block 13. The screw on the screw plate 14 is pressed into the slots of the first rotating head 8 and the second rotating head 11. The clamping bandage 15 is located between the first rotating head 8 and the second rotating head 11.

[0029] Specifically, the workpiece undergoing heat treatment is placed between two clamping straps 15. When the first slider 5 and the second slider 6 move to widen the gap between them, the two clamping straps 15 straighten to reduce the space in the middle, thereby tightening the workpiece. The anti-slip protrusions 16 provide protection. The flexible tension of the clamping straps 15 reduces the deformation caused by clamping. When the first slider 5 and the second slider 6 move to narrow the gap between them, the two clamping straps 15 relax to widen the space in the middle, allowing for contact clamping of the workpiece. Furthermore, the T-shaped mounting block 13, inserted into the first rotating head 8 and the second rotating head 11, allows for quick disassembly and replacement of the T-shaped mounting block 13, enabling the use of different sized clamping straps 15 to clamp workpieces of different sizes.
