Description

Technical Field

[0001] This application relates to the field of machining equipment, and in particular to an adjustable vise for machining curved workpieces. Background Technology

[0002] As an indispensable general-purpose clamping tool in the field of machining, the vise is widely used for fixing and holding workpieces. Whether in metal processing, parts manufacturing, or assembly operations, the vise, with its simplicity and efficiency, has become an important tool for improving machining accuracy and work efficiency. With the rapid development of the manufacturing industry and the ever-increasing demands for workpiece machining accuracy, the vise's role as a basic clamping tool is becoming increasingly important. In the machining of various complex workpieces, the performance of the vise directly affects the machining quality; therefore, the need for functional improvements is becoming increasingly urgent.

[0003] A vise is a general-purpose clamping tool used to hold workpieces and is a common tool in machining processes. When using a vise, the workpiece is placed on a worktable between the movable and fixed jaws. The movable jaws move towards the fixed jaws to clamp the workpiece, and the movable jaws move in the opposite direction to release the workpiece. However, existing vises have a large range of motion when tightening and loosening workpieces, and the clamping force cannot be effectively controlled. This large range of motion and poor clamping force control can easily cause damage to the workpiece. Utility Model Content

[0004] To improve the control of the clamping force of the vise on the workpiece, this application provides an adjustable vise for machining curved workpieces.

[0005] The adjustable vise for machining curved workpieces provided in this application adopts the following technical solution: An adjustable vise for machining curved workpieces includes a fixed vise and a movable vise, with a vise body disposed below the fixed vise and the movable vise; the fixed vise is fixedly mounted on the vise body, and the movable vise is movably mounted on the vise body, with a scale disposed on the vise body; the movable vise can be locked and fixed on the vise body, and the movable vise and the fixed vise cooperate to clamp the workpiece.

[0006] By adopting the above technical solution, stable clamping of the workpiece is achieved. The design of the clamp body provides a stable support foundation, ensuring the structural stability of the vise during use; the setting of the scale can accurately control the movement distance of the movable clamp, thereby effectively improving the control accuracy of the clamping force on the workpiece; the cooperative design of the movable clamp and the fixed clamp makes the workpiece clamping more secure, while facilitating adjustment and fixation, avoiding workpiece damage caused by large movements.

[0007] Preferably, both the fixed clamp and the movable clamp include a clamp body and a support platform, both of which are mounted on the clamp body. The two support platforms are located between the two clamp bodies, and the clamp body is connected to the corresponding support platform.

[0008] By adopting the above technical solution, both the fixed and movable clamps are designed with a structure including a clamp body and a support platform, and the clamp body is connected to the corresponding support platform, which enables the workpiece to obtain a more stable support effect during clamping. The two support platforms are located between the two clamp bodies, which further improves the balance of workpiece clamping, thereby effectively improving the control of the vise's clamping force on the workpiece and reducing the risk of workpiece damage caused by uneven clamping force.

[0009] Preferably, the clamp body is provided with a guide groove, and both the clamp body and the support platform are embedded in the guide groove; the movable clamp body and the support platform can slide along the length direction of the guide groove.

[0010] By adopting the above technical solution, the clamp body and support platform are embedded in the guide groove and can slide along the length of the guide groove, thereby achieving precise movement of the movable clamp. This design effectively reduces the range of motion of the vise when tightening or loosening workpieces, improves the controllability of clamping force, and thus reduces the risk of workpiece damage.

[0011] Preferably, locking blocks and locking pins are provided on both sides of the movable clamp body and support platform; locking grooves are provided on both sides of the movable clamp body and support platform, and mounting grooves are also provided on the side wall of the clamp body; one end of the locking block is inserted into the locking groove and the other end is inserted into the mounting groove, the side wall of the locking block is in contact with the clamp body, one threaded end of the locking pin is screwed onto the locking block, and the other threaded end of the locking pin is screwed onto the clamp body; the locking pin is installed on the support platform of the movable clamp in the same way as it is installed on the clamp body of the movable clamp.

[0012] By adopting the above technical solution, the locking block and locking pin effectively fix the position of the movable jaw and support platform, preventing displacement during workpiece clamping and thus improving the stability of the vise's clamping force. The design of the locking block, with one end inserted into the locking groove and the other end into the mounting groove, allows the locking block to firmly restrict the movement of the movable jaw and support platform, enhancing clamping reliability. The threaded connection between the locking pin and the locking block and jaw body facilitates adjustment of the locking force, enabling precise control of the clamping force and reducing the risk of workpiece damage.

[0013] Preferably, the locking block includes a block body and several friction-reducing rods. The block body has an installation notch on one side near the clamp body, extending through the block body along its length. The block body has friction-reducing semi-grooves on both sides of the installation notch along its width. A friction-reducing hole communicating with the semi-grooves is formed at the bottom of the installation notch. One end of each friction-reducing rod is inserted into the friction-reducing hole, and the other end is embedded in the semi-grooves, with one end of the rod protruding from the semi-grooves. Several positioning grooves for embedding the friction-reducing rods are formed on both the locking groove and the installation groove, arranged sequentially along the length of the clamp body. The inner walls of the block body on both sides of the installation notch are inclined towards the center of the installation notch, and the surfaces of the installation groove and the locking groove that contact the inclined surface of the installation notch are synchronously inclined.

[0014] By adopting the above technical solution, the structural design of the locking block effectively reduces the friction between the block and the clamp body, thereby reducing the operational resistance during locking and unlocking. The cooperation between the friction-reducing rod and the positioning groove enables precise positioning of the locking block at different positions, ensuring the stability of the movable clamp body and support platform when clamping the workpiece. The inclined design of the inner walls on both sides of the mounting notch of the block, as well as the inclined surfaces of the mounting groove and locking groove that match it, further improves the fit between the locking block and the clamp body, enhancing the locking effect. This design improves the control accuracy of the vise's clamping force on the workpiece, while reducing the risk of workpiece damage due to improper operation.

[0015] Preferably, the width of the bottom of the mounting notch is less than the minimum distance between the locking groove and the mounting groove.

[0016] By adopting the above technical solution, the width of the bottom of the mounting notch is less than the minimum distance between the locking groove and the mounting groove, resulting in better positioning of the locking block during installation and effectively preventing the locking block from shaking or misaligning within the mounting notch. This design further improves the stability of the locking structure, thereby enhancing the control accuracy of the vise's clamping force on the workpiece and reducing the risk of workpiece loosening during processing.

[0017] Preferably, the movable clamp has a clamping groove on the top wall of its body facing the clamp body, the bottom of the clamping groove is inclined downwards away from the support platform of the movable clamp, and a clearance groove is formed on the clamp body of the movable clamp near the support platform of the movable clamp, the bottom of the clearance groove being perpendicular to the bottom of the clamping groove; a clamping block is provided in the clamping groove, and a clamping notch is formed on the side of the clamping block near the clamping groove, the inner wall of one side of the clamping notch being able to abut against the bottom of the clamping groove, and the inner wall of the other side of the clamping notch being able to abut against the bottom of the clearance groove; the clamping block can slide in the clamping groove along the inclined direction of the bottom of the clearance groove; an adjustment hole communicating with the clamping notch is formed on the top of the clamping block, and an adjustment bolt is provided in the adjustment hole, the adjustment bolt passing through the clamping groove and threadedly connected to the clamp body of the movable clamp; a reset blind hole is formed at the bottom of the clamping groove, and an elastic element is provided in the reset blind hole, the end of the elastic element away from the reset blind hole abutting against the clamping block.

[0018] By adopting the above technical solution, the clamping block can slide along the inclined direction within the clamping groove, allowing it to automatically adjust its position according to the shape of the workpiece when clamping it, thus improving clamping adaptability. The adjusting bolt design allows users to manually adjust the position of the clamping block, thereby precisely controlling the clamping force and preventing workpiece damage due to excessive clamping force. The elastic element provides a reset function when the workpiece is released, ensuring the clamping block quickly returns to its initial position, improving operational efficiency. The matching design of the clearance groove and the clamping groove allows the clamping block to achieve multi-angle support during clamping, enhancing clamping stability.

[0019] Preferably, a limiting blind hole is formed on the top wall of the clamping notch, and the end of the elastic member away from the reset blind hole is inserted into the limiting blind hole and abuts against the bottom wall of the limiting blind hole.

[0020] By adopting the above technical solution, the installation stability of the elastic element can be improved, ensuring that it always maintains an effective restoring force during use, thereby improving the control accuracy of the vise's clamping force on the workpiece.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The rectangular design of the vise body provides a stable support base, ensuring the structural stability of the vise during use; the scale setting allows for precise control of the moving jaw's movement distance, thereby effectively improving the control accuracy of the workpiece clamping force; the cooperative design of the moving jaw and the fixed jaw makes the workpiece clamping more secure, while facilitating adjustment and fixation, avoiding workpiece damage caused by large movements. 2. The locking block and locking pin effectively fix the position of the movable jaw and support platform, preventing displacement during workpiece clamping and thus improving the stability of the vise's clamping force. The design of the locking block, with one end inserted into the locking groove and the other end into the mounting groove, allows the locking block to firmly restrict the movement of the movable jaw and support platform, enhancing clamping reliability. The threaded connection between the locking pin and the locking block and jaw body facilitates adjustment of the locking force, enabling precise control of the clamping force and reducing the risk of workpiece damage. 3. The clamping block can slide along an inclined direction within the clamping groove, allowing it to automatically adjust its position according to the workpiece's shape when clamping, improving clamping adaptability. The adjusting bolt design allows users to manually adjust the position of the clamping block, thereby precisely controlling the clamping force and preventing workpiece damage due to excessive clamping force. The elastic element provides a reset function when the workpiece is released, ensuring the clamping block quickly returns to its initial position, improving operational efficiency. The matching design of the clearance groove and the clamping groove allows the clamping block to provide multi-angle support during clamping, enhancing clamping stability.

The movable clamp 2's clamp body 4 and the fixed clamp body 4 cooperate to clamp the workpiece. The side wall of the clamp body 3 is provided with a scale 31 along its length. When the movable clamp 2's clamp body 4 moves on the clamp body 3, the distance moved can be accurately known according to the scale 31.

[0033] Reference Figure 2 and Figure 3 Locking blocks 6 are provided on both sides of the clamp body 4 and the support platform 5 of the movable clamp 2. Locking grooves 41 are provided on both sides of the clamp body 4 and the support platform 5 of the movable clamp 2. Mounting grooves 33 are also provided on the side wall of the clamp body 3.

[0037] The block 61 has anti-friction semi-grooves 612 on both sides of the mounting notch 611 in the width direction of the clamp body 3. The bottom of the block 61 in the mounting notch 611 has an anti-friction hole 613 communicating with the anti-friction semi-grooves 612. One end of the anti-friction rod 62 is inserted into the anti-friction hole 613 and the other end is embedded in the anti-friction semi-grooves 612.

Several positioning grooves 34 for embedding the anti-friction rod 62 are provided on both the locking groove 41 and the mounting groove 33. The positioning grooves 34 are arranged sequentially along the length direction of the clamp body 3. Each time the clamp body 4 and the support platform 5 of the movable clamp 2 are adjusted, the locking pin 7 must be unscrewed first to disengage part of the block 61 from the locking groove 41 and the mounting groove 33, so that the anti-friction rod 62 can be completely disengaged from the anti-friction semi-grooves 612 and slide smoothly on the clamp body 3.

[0038] Reference Figure 4 and Figure 5 When the clamp body 4 and support platform 5 of the movable clamp 2 move to the corresponding positions, the workpiece is placed on the support platform 5.

The bottom of the clamping groove 42 is inclined downward towards the support platform 5 away from the movable clamp 2. The clamp body 4 of the movable clamp 2 is provided with a clearance groove 43 in the direction close to the support platform 5.

[0041] The implementation principle of an adjustable vise for machining curved workpieces according to an embodiment of this application is as follows: When machining the same type of workpiece (such as an automobile tire mold), the position of the movable vise body 4 is adjusted according to the length or width of the workpiece. After the vise body 4 of the movable vise 2 moves to the corresponding position, the locking pin 7 is tightened to fix the jaw of the movable vise 2 at this position until the next type of workpiece is changed and then adjusted again; the workpiece is placed on the support table 5, and after positioning, the adjusting bolt 45 is rotated. The obliquely set adjusting bolt 45 drives the clamping block 44 to move, thereby clamping the workpiece; the adjusting bolt 45 is rotated in the opposite direction, and the elastic element 422 lifts one end of the clamping block, and the clamping block returns to its original position, thereby releasing the workpiece. Through the vise body 3 with the scale 31, the vise body 4 of the movable vise 2 can accurately move the corresponding distance, thereby improving the control of the vise's clamping force on the workpiece.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
