Description

Technical Field

[0001] This application relates to the technical field of workpiece clamping, and in particular to an easy-to-use clamp. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix and position a workpiece, ensuring that it occupies the correct position for processing or inspection. Also known as a clamp, it can be used to hold the workpiece to prevent it from shifting, so as to facilitate the processing of the workpiece.

[0003] In the production and processing process, it is usually necessary to use fixtures to fix the workpiece. There are two types of conventional fixtures: one is horizontal clamping (such as three-jaw chucks); the other is vertical downward pressing (such as common quick clamps, hydraulic fixtures, etc.). However, for some workpieces with a conical outer surface, it is difficult to achieve stable clamping and fixing using the above two methods. Therefore, it is necessary to propose a fixture that is easy to use to solve the above problems. Summary of the Invention

[0004] To address the problem that existing conventional fixtures are unable to stably clamp and fix certain workpieces with tapered outer surfaces, this application provides a fixture that is easy to use.

[0005] This application provides a user-friendly clamp, which adopts the following technical solution: A user-friendly clamp includes a base, a placement plate fixedly mounted on the top of the base, first fixing plates fixedly mounted on the left and right sides of the top of the placement plate, the upper surface of the first fixing plates being inclined, a first clamping block slidably connected to the top of the first fixing plates via a slider, the inner surface of the first clamping block being inclined, and first push plates provided on the left and right outer sides of the first clamping block, with adjusting components for adjusting the position of the first push plates provided on the left and right sides of the placement plate; a pair of second fixing plates fixedly mounted on the front and rear sides of the top of the placement plate, the upper surface of the second fixing plates being inclined, a second clamping block slidably connected to the top of the first fixing plates via a movable block, the inner surface of the second clamping block being inclined, and second push plates provided on the front and rear outer sides of the second clamping block, with movable components for adjusting the position of the second push plates provided on the front and rear sides of the placement plate.

[0006] Through the cooperation between the first fixed plate and the first clamping block, as well as the second fixed plate and the second clamping block, and by opening inclined surfaces on their surfaces, the first push plate and the second push plate can push the first clamping block and the second clamping block obliquely downwards respectively, thereby limiting the workpiece with a conical outer surface, thus achieving outer and top limiting and improving clamping stability. At the same time, by sliding the first clamping block on the top of the first fixed plate and the second clamping block on the top of the second fixed plate, the positions of the first clamping block and the second clamping block can be flexibly adjusted according to the specific size of the workpiece, further adapting to the clamping requirements of workpieces of different specifications.

[0007] A further improvement of the technical solution of this application is that: a first movable plate is rotatably installed on the inner side of the inclined surface of the first clamping block, a plurality of second springs are fixedly installed on the outer side of the first movable plate, the outer side of the second springs is fixedly connected to the inner wall of the first clamping block, and a first rubber pad is attached to the inner surface of the first movable plate.

[0008] By adopting the above technical solution, the first movable plate and the second spring cooperate with each other. The first movable plate is rotated between the first movable plate and the first clamping block. As the first clamping block approaches the workpiece, the first movable plate can rotate synchronously with the different inclinations of the workpiece's conical surface. At the same time, the second spring squeezes the first movable plate to dynamically adjust the rotation angle of the first movable plate. This allows for clamping and limiting of workpieces with different conical surfaces from both the left and right sides, thus expanding the applicability of the device.

[0009] A further improvement of the technical solution of this application is that: a second movable plate is rotatably installed on the inner side of the inclined surface of the second clamping block, a number of fourth springs are fixedly installed on the outer side of the second movable plate, the outer side of the fourth springs is fixedly connected to the inner wall of the second clamping block, and a second rubber pad is attached to the inner surface of the second movable plate.

[0010] By adopting the above technical solution, the second movable plate and the fourth spring cooperate with each other. The second movable plate is rotated between the second movable plate and the second clamping block. As the second clamping block approaches the workpiece, the second movable plate can rotate synchronously with the different inclinations of the workpiece's conical surface. At the same time, the fourth spring squeezes the second movable plate to dynamically adjust the rotation angle of the second movable plate. This allows for clamping and limiting of workpieces with different conical surfaces from both the front and rear sides, thus expanding the applicability of the device.

[0011] A further improvement of the technical solution of this application is that: the adjusting component includes a pair of guide blocks, the guide blocks are fixedly connected to the bottom of the first push plate, and fixed frames are fixedly installed on both the left and right sides of the placement plate. A bidirectional screw is rotatably connected to the inner side of the fixed frame. The bidirectional screw passes through the interior of the placement plate, and the outer surface of the bidirectional screw is threadedly connected to the guide block. A first handwheel is provided on the left side of the fixed frame on the left side of the placement plate, and the first handwheel is fixedly connected to the left side of the bidirectional screw.

[0012] In the above technical solution, by adjusting the cooperation between the components, the rotation of the bidirectional lead screw can synchronously drive the two guide blocks to move, so that the two first push plates move closer to each other and push the two first clamping blocks, so that the workpiece can be clamped by the first clamping blocks. There is no need to move each first clamping block separately, which reduces the operation steps and improves the work efficiency.

[0013] A further improvement of the technical solution of this application is that: a plurality of first balls are rolledly installed on the inner surface of the first push plate, and the first balls are rolledly connected to the left and right outer sides of the first clamping block.

[0014] In the above technical solution, during the process of the first push plate pushing the first clamping block to move, the first clamping block will slide obliquely downward along the inner side of the first push plate. The first ball bearing can be installed to separate the first push plate from the first clamping block, and the first ball bearing can roll, thereby reducing the wear between the first push plate and the first clamping block and extending the service life of the device.

[0015] A further improvement of the technical solution of this application is that: the movable part includes a pair of guide blocks, the guide blocks are fixedly connected to the bottom of the second push plate, and connecting frames are fixedly installed on both the front and rear sides of the placement plate. A bidirectional screw is rotatably connected to the inner side of the connecting frame. The bidirectional screw passes through the interior of the placement plate and is located at the bottom of the bidirectional lead screw. The outer surface of the bidirectional screw is threadedly connected to the guide block. A second handwheel is provided on the front side of the connecting frame on the front side of the placement plate. The second handwheel is fixedly connected to the front side of the bidirectional screw.

[0016] In this technical solution, the movement of the two guide blocks is synchronously driven by the rotation of the bidirectional screw, which brings the two second push plates closer together and pushes the two second clamping blocks. This allows the workpiece to be clamped using the second clamping blocks, eliminating the need to move each second clamping block individually, reducing the number of operation steps and improving work efficiency.

[0017] A further improvement of the technical solution of this application is that: a number of second balls are rolled on the inner surface of the second push plate, and the second balls are rolled to the front and rear outer sides of the second clamping block.

[0018] In the above technical solution, during the process of the second push plate pushing the second clamping block to move, the second clamping block will slide obliquely downward along the inner side of the second push plate. The second ball bearing can be installed to separate the second push plate from the second clamping block, and the second ball bearing can roll, thereby reducing the wear between the second push plate and the second clamping block and extending the service life of the device.

[0019] A further improvement of the technical solution of this application is that: the slider is internally slidably connected to the first fixed plate, a first spring is fixedly installed on the inner side of the slider, and the inner side of the first spring is fixedly connected to the inner wall of the first fixed plate.

[0020] By adopting the above technical solution, the installation of the first spring can generate an upward thrust on the slider, thereby squeezing the first clamping block to ensure that the first clamping block is in contact with the surface of the first ball, thus preventing the first clamping block from moving downward to the bottom before the workpiece is placed, which would affect the placement of the workpiece.

[0021] A further improvement of the technical solution of this application is that: the movable block is internally slidably connected to the second fixed plate, a third spring is fixedly installed on the inner side of the movable block, and the inner side of the third spring is fixedly connected to the inner wall of the second fixed plate.

[0022] By adopting the above technical solution, the installation of a third spring can generate an upward oblique thrust on the movable block, thereby squeezing the second clamping block to ensure that the second clamping block is in contact with the surface of the second ball, thus preventing the second clamping block from moving downward obliquely to the bottom before the workpiece is placed, which would affect the placement of the workpiece.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. This application provides a user-friendly clamp. By opening inclined surfaces on the surfaces of the first fixed plate and the first clamping block, as well as the second fixed plate and the second clamping block, the first push plate and the second push plate can push the first clamping block and the second clamping block obliquely downwards respectively, thereby limiting the workpiece with a conical outer surface, thus achieving external and top limiting and improving clamping stability.

[0024] 2. This application provides a user-friendly clamp. By setting a first movable plate and a second spring, as well as a second movable plate and a fourth spring, when the first clamping block and the second clamping block approach the workpiece, both the first movable plate and the second movable plate can rotate synchronously according to the different inclinations of the workpiece's conical surface. At the same time, the second spring and the fourth spring respectively squeeze the first movable plate and the second movable plate, thereby clamping and limiting workpieces with different conical surfaces, expanding the applicability of the device.

[0025] 3. This application provides a user-friendly clamp. By setting adjustment and movable parts, it is possible to push two first clamping blocks and a second clamping block simultaneously to clamp the workpiece. There is no need to move each first clamping block and the second clamping block separately, which reduces the operation steps and improves work efficiency. Furthermore, the first spring and the third spring can respectively generate an upward oblique pushing force on the slider and the movable block, which prevents the first clamping blocks and the second clamping blocks from moving downward obliquely to the bottom before the workpiece is placed, thus affecting the placement of the workpiece.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] Example 1 See Figure 1 , Figure 2 and Figure 4This application provides a user-friendly clamp, including a base 1, a placement plate 2 fixedly mounted on the top of the base 1, first fixing plates 7 fixedly mounted on the left and right sides of the top of the placement plate 2, the upper surface of the first fixing plates 7 being inclined, the top of the first fixing plates 7 being slidably connected to a first clamping block 3 via a slider 14, the inner surface of the first clamping block 3 being inclined, the left and right outer sides of the first clamping block 3 being provided with first push plates 11, and the left and right sides of the placement plate 2 being provided with adjustment components for adjusting the position of the first push plates 11; a pair of second fixing plates 24 fixedly mounted on the front and rear sides of the top of the placement plate 2, the upper surface of the second fixing plates 24 being inclined, the top of the first fixing plates 7 being slidably connected to a second clamping block 4 via a movable block 25, the inner surface of the second clamping block 4 being inclined, the front and rear outer sides of the second clamping block 4 being provided with a second push plate 21, and the front and rear sides of the placement plate 2 being provided with movable components for adjusting the position of the second push plate 21.

[0030] In this embodiment, through the cooperation between the first fixing plate 7 and the first clamping block 3, as well as the second fixing plate 24 and the second clamping block 4, and by opening inclined surfaces on their surfaces, the first push plate 11 and the second push plate 21 can push the first clamping block 3 and the second clamping block 4 obliquely downwards respectively, thereby limiting the workpiece with a conical outer surface, thus achieving external and top limiting and improving clamping stability. At the same time, by sliding the first clamping block 3 on the top of the first fixing plate 7 and the second clamping block 4 on the top of the second fixing plate 24, the positions of the first clamping block 3 and the second clamping block 4 can be flexibly adjusted according to the specific size of the workpiece, further adapting to the clamping requirements of workpieces of different specifications.

[0031] Example 2 See Figure 1 , Figure 3 and Figure 5 Based on Embodiment 1, this application provides a technical solution: Preferably, a first movable plate 12 is rotatably installed on the inner side of the inclined surface of the first clamping block 3, and a plurality of second springs 16 are fixedly installed on the outer side of the first movable plate 12. The outer side of the second springs 16 is fixedly connected to the inner wall of the first clamping block 3, and a first rubber pad 17 is attached to the inner surface of the first movable plate 12.

The outer side of the fourth springs 27 is fixedly connected to the inner wall of the second clamping block 4. A second rubber pad 28 is attached to the inner surface of the second movable plate 22.

[0032] In this embodiment, through the cooperation between the first movable plate 12 and the second spring 16, the first movable plate 12 is rotatably set with the first clamping block 3. As the first clamping block 3 approaches the workpiece, the first movable plate 12 can rotate synchronously with the different inclinations of the workpiece's conical surface. At the same time, the second spring 16 presses the first movable plate 12, thereby dynamically adjusting the rotation angle of the first movable plate 12. This allows for clamping and limiting of workpieces with different conical surfaces from both the left and right sides, expanding the applicability of the device. Through the cooperation between the second movable plate 22 and the fourth spring 27, the second movable plate 22 is rotatably set between the second movable plate 22 and the second clamping block 4. As the second clamping block 4 approaches the workpiece, the second movable plate 22 can rotate synchronously with the different inclinations of the workpiece's conical surface. At the same time, the fourth spring 27 presses the second movable plate 22, realizing the dynamic adjustment of the rotation angle of the second movable plate 22. This allows for clamping and limiting of workpieces with different conical surfaces from both the front and rear sides, expanding the applicability of the device.

[0033] Example 3 See Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on Embodiment 2, this application provides a technical solution: Preferably, the adjusting component includes a pair of guide blocks 9, the guide blocks 9 are fixedly connected to the bottom of the first push plate 11, and the left and right sides of the placement plate 2 are fixedly installed with fixing frames 8. The inner side of the fixing frame 8 is rotatably connected with a bidirectional screw 5, which passes through the interior of the placement plate 2. The outer surface of the bidirectional screw 5 is threadedly connected to the guide blocks 9. The left side of the fixing frame 8 on the left side of the placement plate 2 is provided with a first handwheel 10, which is fixedly connected to the left side of the bidirectional screw 5. A plurality of first balls 13 are rolledly installed on the inner surface of the first push plate 11, and the first balls 13 are rolledly connected to the left and right outer sides of the first clamping block 3. The movable parts include a pair of guide blocks 19, which are fixedly connected to the bottom of the second push plate 21. Connecting brackets 18 are fixedly installed on both the front and rear sides of the placement plate 2. A bidirectional screw 6 is rotatably connected to the inner side of the connecting bracket 18. The bidirectional screw 6 passes through the interior of the placement plate 2 and is located at the bottom of the bidirectional lead screw 5. The outer surface of the bidirectional screw 6 is threadedly connected to the guide blocks 19. A second handwheel 20 is provided on the front side of the connecting bracket 18 on the front side of the placement plate 2. The second handwheel 20 is fixedly connected to the front side of the bidirectional screw 6. A plurality of second balls 23 are rolled on the inner surface of the second push plate 21. The second balls 23 are rolledly connected to the front and rear outer sides of the second clamping block 4. The slider 14 is slidably connected to the inside of the first fixed plate 7. A first spring 15 is fixedly installed on the inside of the slider 14, and the inside of the first spring 15 is fixedly connected to the inner wall of the first fixed plate 7. The movable block 25 is slidably connected to the inside of the second fixed plate 24. A third spring 26 is fixedly installed on the inside of the movable block 25, and the inside of the third spring 26 is fixedly connected to the inner wall of the second fixed plate 24.

[0034] In this embodiment, by adjusting the cooperation between the components, the rotation of the bidirectional lead screw 5 can synchronously drive the two guide blocks 9 to move, so that the two first push plates 11 move closer to each other and push the two first clamping blocks 3, so that the workpiece can be clamped by the first clamping blocks 3. There is no need to move each first clamping block 3 separately, which reduces the operation steps and improves the work efficiency. During the process of the first push plate 11 pushing the first clamping block 3 to move, the first clamping block 3 will slide obliquely downward along the inner side of the first push plate 11. The first ball bearing 13 can separate the first push plate 11 from the first clamping block 3 and can roll, thereby reducing the wear between the first push plate 11 and the first clamping block 3 and extending the service life of the device. Through the cooperation between the moving parts, the rotation of the bidirectional screw 6 can synchronously drive the two guide blocks 19 to move, so that the two second push plates 21 move closer to each other and push the two second clamping blocks 4, so that the workpiece can be clamped by the second clamping blocks 4. There is no need to move each second clamping block 4 separately, which reduces the operation steps and improves the work efficiency. During the process of the second push plate 21 pushing the second clamping block 4 to move, the second clamping block 4 will slide obliquely downward along the inner side of the second push plate 21. The second ball bearing 23 can separate the second push plate 21 from the second clamping block 4 and can roll, thereby reducing the wear between the second push plate 21 and the second clamping block 4 and extending the service life of the device. By installing the first spring 15, an upward pushing force can be generated on the slider 14, thereby squeezing the first clamping block 3 to ensure that the first clamping block 3 is in contact with the surface of the first ball 13, and to prevent the first clamping block 3 from moving downward to the bottom before the workpiece is placed, thus affecting the placement of the workpiece; by installing the third spring 26, an upward pushing force can be generated on the movable block 25, thereby squeezing the second clamping block 4 to ensure that the second clamping block 4 is in contact with the surface of the second ball 23, and to prevent the second clamping block 4 from moving downward to the bottom before the workpiece is placed, thus affecting the placement of the workpiece.

[0035] The working principle of this fully automatic multi-axis winding machine is explained in detail below.

[0036] like Figures 1-5As shown, the operator places the conical workpiece on top of the placement plate 2, then rotates the first handwheel 10, causing the bidirectional screw 5 to rotate, which in turn moves the guide block 9, causing the two first push plates 11 to push the first clamping block 3. The second spring 16 is used to adjust the angle of the first movable plate 12, so that the first rubber pad 17 is in contact with the left and right sides of the workpiece. Then, the second handwheel 20 is rotated, causing the bidirectional screw 6 to rotate, which in turn moves the guide block 19, causing the two second push plates 21 to push the second clamping block 4. The fourth spring 27 is used to adjust the angle of the second movable plate 22, so that the second rubber pad 28 is in contact with the left and right sides of the workpiece, thereby achieving clamping and limiting of the workpiece to facilitate processing.
