A new type of clamp

Abstract

A novel clamping fixture includes a housing, a fixed clamping arm, a movable clamping arm, and a control base. A connecting member is provided between the movable clamping arm and the control base. The control base has a control groove. One end of the connecting member is connected to the movable clamping arm, and the other end of the connecting member extends into the control base and connects to the control groove. The end of the connecting member extending into the control base can move along the length of the control groove. This application uses a sliding movable clamping arm in conjunction with the fixed clamping arm to laterally clamp the product to be processed. Compared with traditional rotary clamping fixtures, it is not limited by the shape of the workpiece and has a wider adaptability. At the same time, the movable clamping arm can be driven to complete the clamping action by pulling the connecting member through the control base. The overall structure is simple. During the clamping process, the movable clamping arm only moves in a straight line with small sway amplitude and higher clamping stability. With the help of the limiting protrusion, the end of the product to be processed is limited, which can ensure the accurate placement of the product to be processed and improve the accuracy of subsequent processing.

Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and specifically to a novel clamping fixture. Background Technology

[0002] Fixtures are used in mechanical manufacturing to fix workpieces in the correct position for machining. Fixtures for fixing parts to be machined, such as wire terminals, are crucial. Existing fixtures typically clamp the workpiece by rotating the clamping arms. This structure limits the rotation angle of the clamping arms to some workpiece shapes, making it impossible to clamp them properly. Some lateral-shifting fixtures have an integrated design of the chuck and clamping arms, which is inconvenient for disassembly and replacement. Furthermore, when the workpiece is transferred to the fixture, it is prone to misalignment or being placed too deep, resulting in low machining accuracy. Utility Model Content

[0003] In view of this, the present invention provides a novel clamp.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel clamp includes a control base, a fixed clamping arm, and a movable clamping arm. The control base has a movable slot.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] This utility model provides the following technical solution:

[0027] according to Figure 1-5As shown, a novel clamp includes a control base 4, a fixed clamping arm 2, and a movable clamping arm 3. The control base 4 has a movable groove 8. One end of the fixed clamping arm 2 extends into the movable groove 8 and connects to the control base 4. The movable clamping arm 3 includes a clamping arm body 32 and a connecting member 6. The connecting member 6 is detachably connected to the clamping arm body 32 and supports the clamping arm body 32. One side of the connecting member 6 extends into the movable groove 8 and is movably connected to the control base 4. During the movement of the control base 4, the connecting member 6 drives the clamping arm body 32 to clamp and release relative to the fixed clamping arm 2. In this embodiment, the connecting member 6 transmits power, allowing the pulling action of the control base 4 to be converted into a releasing movement of the clamping arm body 32 away from the fixed clamping arm 2. In this embodiment, the connecting member 6 transmits power, allowing the pushing action of the control base 4 to be converted into a movement of the clamping arm body 32 moving closer to the fixed clamping arm 2. The linear motion of the control base is converted into the opening and closing action of the clamping arm body driven by the connecting member. The overall transmission structure is simple and reliable, with a lower probability of failure. The clamping arm body 32 and the connecting piece 6 are designed to be detachably connected, which facilitates the installation and disassembly of the clamping arm body 32 and the connecting piece 6, making the whole system adaptable to more situations during use. In this embodiment, there is a gap between the fixed clamping arm 2 and the movable clamping arm 3, and there is also a gap between the fixed clamping arm 2 and the connecting piece 6.

[0028] according to Figure 2-5 As shown, a clamping arm connecting groove 15 is formed on the side of the clamping arm body 32 near the control seat 4, and one side of the connector 6 extends into the clamping arm connecting groove 15 to connect with the clamping arm body 32. In this embodiment, the clamping arm connecting groove 15 provides positioning and installation space for the connection between the connector 6 and the clamping arm body 32. During assembly, the connector 6 can be quickly aligned and placed in the corresponding position, reducing the difficulty of alignment during assembly. At the same time, it can also ensure the stability of the connection position between the connector 6 and the movable clamping arm 3, and prevent the connector 6 from shaking or shifting during use.

[0029] according to Figure 2-5As shown, the portion of the connector 6 extending into the movable groove 8 has a moving hole 9. The control seat 4 has a control groove 7 inclined towards the fixed clamping arm 2. The control groove 7 is elongated, and the moving hole 9 is positioned corresponding to the control groove 7. A shaft is installed within the moving hole 9, with a portion of the shaft extending out of the moving hole 9 and into the control groove 7. The shaft drives the connector 6 to move within the control groove 7. In this embodiment, the shaft slides along the groove wall within the control groove 7, directly transmitting the trajectory restriction effect of the control groove 7 to the connector 6. This ensures that the moving direction of the connector 6 is always consistent with the preset extension direction of the control groove 7, preventing the connector 6 from deviating during movement and ensuring stable clamping action. The clearance fit between the shaft and the moving hole 9 ensures smooth rotation of the shaft, reduces friction during movement, and avoids jamming that could affect the normal use of the clamp. The structure is simple, and the transmission reliability is high. (Shaft not shown in the diagram)

[0030] according to Figure 2-4 As shown, one end of the fixed clamping arm 2 that extends into the movable groove 8 protrudes to form a connecting part 10. The control seat 4, corresponding to the position of the connecting part 10, is recessed to form a connecting groove 11. The connecting part 10 extends into the connecting groove 11, connecting the fixed clamping arm 2 and the control seat 4. A control part 12 is formed on the side of the control seat 4 away from the fixed clamping arm 2. A transmission hole 13 is provided on the control part 12, and a limiting rod 14 is provided within the transmission hole 13. In this embodiment, the fixed clamping arm 2 and the control seat 4 are connected through the connecting part 10 and the connecting groove 11. During assembly, the connecting part 10 can be directly aligned and inserted into the connecting groove 11 to complete the positioning of both, simplifying the assembly process. Simultaneously, this plug-in connection method provides stronger structural stability, preventing relative displacement between the fixed clamping arm 2 and the control seat 4 during use, further ensuring clamping accuracy. In this embodiment, the limiting rod 14 transmits tension to the control seat 4, causing the control seat 4 to move, thereby controlling the movable clamping arm 3 to loosen away from the fixed clamping arm 2 and away from the product 18 to be processed. In this embodiment, a pressure hole is provided on the side wall of the transmission hole 13, and a transmission hole is provided at the corresponding position on the limiting rod 14. The two are connected by a pin, and the control seat 4 is moved by pressing down one end of the limiting rod.

[0031] according to Figure 1 , 2As shown, the device also includes a housing 1, within which a movable groove 5 is formed. The control seat 4, fixed clamping arm 2, and movable clamping arm 3 are all disposed within the movable groove 5. The housing 1 also has a control hole 31. A swing hole 33 is provided on the connecting member 6 corresponding to the position of the control hole 31. The control hole 31 and the swing hole 33 are connected by a shaft (not shown in the diagram). The connecting member 6 swings around the swing hole 33. In this embodiment, one end of the connecting member 6 extends into the clamping arm body 32, and the other end extends into the control seat 4. When the control seat 4 moves, it can drive the connecting member 6 to rotate around the shaft of the swing hole 33, thereby driving the clamping arm body to complete the movement of approaching and moving away from the fixed clamping arm. This converts the linear motion of the control seat 4 into the swing opening and closing of the clamping arm body 32, resulting in a simple and reliable transmission structure. When the control seat 4 is pulled outward, the connector 6 moves along the inclined control groove 7 with one end centered on the control hole 31, and the other end drives the movable clamping arm 3 to gradually move away from the fixed clamping arm 2, thereby completing the release of the clamp. This inclined groove design does not require an additional transmission structure to complete the conversion of force direction, making the structure simpler and more compact, and reducing the difficulty of processing and assembly.

[0032] according to Figure 1-5 As shown, a fixed seat 27 is also provided below the control seat 4. An elastic element 28 is provided between the fixed seat 27 and the control seat 4. The elastic element 28 pushes the control seat 4 to move towards the fixed clamping arm 2. The control seat 4 drives the clamping arm body 32 to move towards the fixed clamping arm 2 via the connecting member 6. In this embodiment, the connecting member 6 transmits power, allowing the pulling action of the control seat 4 to be converted into a releasing movement of the clamping arm body 32 away from the fixed clamping arm 2. The control groove 7 provides guidance and force support to the connecting member 6 when the control seat 4 drives the connecting member 6 to move outward as a whole. By utilizing the inclined extension trajectory of the control groove 7, the axial pulling action of the control seat 4 is converted into a lateral pulling action of the connecting member 6 driving the movable clamping arm 3, simplifying the operation steps and overall structure of the fixture, and making the clamping operation more convenient and efficient. When the elastic element 28 pushes the control seat 4 towards the fixed clamping arm 2, the shaft moves in the opposite direction along the control groove 7, and the movable clamping arm 3 gradually approaches the fixed clamping arm 2, realizing the clamping action of the workpiece. In this embodiment, the elastic element 28 is a spring.

[0033] according to Figure 1 , 2As shown in Figure 5, each of the fixed clamping arm 2 and the movable clamping arm 3 has a corresponding chuck 16 on the portion extending out of the moving groove 5. A fixing groove 17 is formed between the chucks 16, and the product to be processed 18 is placed within the fixing groove 17. In this embodiment, the position of the chucks 16 can be adjusted according to the processing requirements of the product to be processed 18. Several fixing holes 20 are evenly distributed on the top of the fixed clamping arm 2 and the movable clamping arm 3. Clamping holes 21 are provided on the chucks 16. The connection between the clamping holes 21 and different fixing holes 20 allows for adjustment of the position of the chucks 16 and the setting of fixing grooves 17 of different lengths. The fixing grooves 17 stably support the product to be processed 18, preventing displacement during processing and ensuring processing accuracy. The two chucks 16 move synchronously with the fixed clamping arm 2 and the movable clamping arm 3, respectively. The opening and closing action directly acts on the product, resulting in direct clamping force transmission and stable clamping effect.

[0034] according to Figure 1 , 2 As shown in Figure 5, both the fixed clamping arm 2 and the movable clamping arm 3 are provided with several limiting protrusions 22 on the side away from the control seat 4. These limiting protrusions 22 limit the position of the product to be processed 18 within the fixed groove 17. In this embodiment, the function of the limiting protrusions 22 is to restrict the position of the product to be processed 18 within the fixed groove 17, ensuring the accuracy of the position when the product to be processed 18 is loaded into the fixture, and avoiding inaccurate positioning during loading. In this embodiment, the movable clamping arm 3 moves laterally, and the product to be processed 18 is loaded into the fixed groove 17 longitudinally. The limiting protrusions 22 prevent the product to be processed 18 from excessively extending longitudinally into the fixed groove 17 when loaded, thus avoiding a decrease in processing accuracy.

[0035] according to Figure 2 , 5 As shown, the movable clamping arm 3 is also provided with a limiting groove 23, which connects the clamping arm connecting groove 15 to the outside. The connector 6 is provided with a clamping arm connecting hole 24, which is positioned corresponding to the limiting groove 23. In this embodiment, the limiting groove 23 facilitates the installation and removal of the connector 6 and the movable clamping arm 3, allowing for quick and accurate positioning of the connector 6 on the movable clamping arm 3. Simultaneously, the limiting groove 23 also restricts the positional deviation of the connector 6 during use, preventing it from loosening and further improving the stability of the entire clamping connection structure, ensuring the reliability of the transmission and clamping action during long-term use.

[0036] In this application, the chuck 16 has a clamping part 25 and a limiting part 26. The clamping part 25 is disposed on the fixed clamping arm 2 and the movable clamping arm 3. The limiting part 26 is disposed on the side of the clamping part 25 near the product 18 to be processed, and the limiting part 26 limits the vertical movement of the product 18 to be processed. The clamping part 25 directly fits against the side wall of the product to be processed, providing lateral clamping force to ensure that the product does not move horizontally. The limiting part 26 protrudes from the inside of the clamping part 25, and can press the product to be processed from above, limiting the product's jumping or displacement in the vertical direction. With the support of the bottom fixing groove 17 and the side clamping, the product to be processed is limited and fixed from multiple dimensions, further improving the stability of the product after clamping and ensuring processing accuracy. At the same time, this split-type chuck structure can replace the clamping part or limiting part of different specifications according to the shape and size of the product to be processed, further improving the adaptability of the fixture.

[0037] according to Figure 4 , 5 As shown, the fixed base 27 has an elastic groove 29 corresponding to the position of the elastic element 28. One end of the elastic element 28 extends into the elastic groove 29 and connects to the fixed base 27. The fixed base 27 also has a clearance groove 30, which is positioned corresponding to the position of the control part 12. Pulling the control seat 4 causes the control part 12 to extend into the clearance groove 30. In this embodiment, the fixed base 27 can be fixedly mounted on the workbench or work tray. The function of the fixed base 27 is to provide installation and limiting space for the elastic element 28. After one end of the elastic element is inserted into the elastic groove, it will not shift laterally and can always apply a stable elastic force to the control seat along the axial direction, ensuring stable transmission of elastic force. The clearance groove provides movement and clearance space for the control part. When the control seat is pulled to release the clamp, the control part can extend into the clearance groove without structural interference with the fixed base, ensuring that the release action can be completed smoothly. It also makes the overall structure more compact and reduces the space occupied by the clamp.
