Description

Technical Field

[0001] The utility model relates to the technical field of hoisting fixtures, in particular to a height-adjustable clamping device and a hoisting fixture formed by the clamping device. Background Art

[0002] When injection molded workpieces or other workpieces need to be hoisted for processing, two symmetrical clamping assemblies are usually used to clamp the two ends of the workpiece. The position and height of the existing clamping assemblies are fixed. If the heights of the two ends of the workpiece are inconsistent after clamping, auxiliary tools such as pads need to be used to level the clamping assemblies according to the height difference.

[0003] In the process of height adjustment using auxiliary tools, it is necessary to frequently install or remove the workpiece, or to constantly replace the pads of different thicknesses, and the ideal effect can only be achieved after repeated debugging. This results in a large waste of debugging time in the process of hoisting and clamping, while increasing the labor intensity of the operators and reducing the efficiency of hoisting and clamping processing. Utility Model Content

[0004] In order to overcome the problems existing in the related art, one of the purposes of the utility model is to provide a height-adjustable clamping device, which can adjust the height of the clamping assembly by lifting and rotating the two ends of the pedal, thereby improving the efficiency and accuracy of the height adjustment of the clamping device.

[0005] A height-adjustable clamping device includes a rotating adjustment member, which includes a pedal and a fixed shaft located at the center of the pedal. Both sides of the pedal can rotate relative to the axis of the fixed shaft. One side of the pedal is connected to the adjustment control member, and the other side of the pedal is connected to the clamping assembly. The clamping assembly is provided with a clamping member for fixing a workpiece.

[0006] Since the position of the fixed shaft is fixed, the fixed shaft and the pedal together form a seesaw structure. When the adjustment control presses one side of the pedal or moves away from the side of the pedal, the position and height of the clamping assembly will change. By controlling the position of the adjustment control, the height of the clamping assembly can be accurately controlled, thereby achieving adjustment of the height of the workpiece clamping position. The present application can avoid the defects of frequent debugging in the prior art and improve the efficiency and accuracy of adjustment of the clamping device.

[0007] In a preferred technical solution of the utility model, it also includes an adjustment shell, the adjustment shell is provided with a hollow chamber, and the rotating adjustment member is located inside the hollow chamber.

[0008] The present application uses an adjustment shell to wrap the rotating adjustment part, which can ensure that the rotating adjustment part acts as a whole, is easy to install and clamp, is suitable for various clamping occasions, expands the application scope of the clamping device, and facilitates the installation and disassembly of the clamping device.

[0009] In a preferred technical solution of the utility model, a first through hole for the clamping assembly to extend out is provided on the top of the adjusting shell, and a second through hole for the adjusting control unit to extend out is provided on the top of the adjusting shell.

[0010] In the present application, the bottom of the adjustment control is set inside the adjustment housing, and the top is set outside the adjustment housing, so that it is convenient for the operator to press or lift the adjustment control. The adjustment control is an active control part, and the clamping assembly is a passive lifting part. The operating end of the active control part is set outside the adjustment housing, which can be convenient for the operator to operate and can also facilitate the operator to accurately adjust the lifting height. The bottom of the clamping assembly is set inside the adjustment housing, and the top is also set outside the adjustment housing. A clamping part needs to be set on the top. The clamping part is used to clamp the tooling. Specifically, it can be based on the processing requirements of the workpiece to ensure that the clamping part exposes the surface to be processed of the workpiece when clamping the workpiece.

[0011] In a preferred technical solution of the present utility model, a third through hole is provided on the side wall of the adjusting shell, and the fastener passes through the third through hole and abuts against the side wall of the clamping assembly.

[0012] During the lifting and lowering adjustment of the clamping assembly, the fastener is far away from the clamping assembly. At this time, the fastener and the clamping assembly do not abut, and the fastener is not limited. After the lifting position of the clamping assembly is determined, tighten the fastening screw so that the fastening screw abuts against the clamping assembly to form a limit for the clamping assembly, ensuring that the height of the clamping assembly in the vertical direction is constant and avoiding position deviation of the clamping assembly after leveling.

[0013] In a preferred technical solution of the utility model, the abutting surfaces of the clamping assembly and the fastener are inclined surfaces that match each other.

[0014] Specifically, the abutting surface of the clamping assembly can be set as a downward inclined surface, and the abutting surface of the fastener can be set as an upward inclined surface. When the clamping assembly and the fastener abut, the two abutting inclinations are just adapted. Since the clamping assembly is lifted and lowered in the vertical direction, in order to avoid relative displacement between the fastener and the clamping assembly, the abutting surfaces of the two are set as inclined surfaces, and one is an upward inclined surface and the other is a downward inclined surface, which fit and abut in the vertical direction to avoid displacement of the clamping assembly and the fastener in the vertical direction.

[0015] In a preferred technical solution of the utility model, the fixed shaft is fixed in the adjustment housing; the angle of rotation of the two sides of the pedal around the axis of the fixed shaft is 0-10°.

[0016] In a preferred technical solution of the present utility model, the lifting height of the clamping assembly is 0-22.6 mm.

[0017] In order to ensure that the horizontal position of the clamping assembly does not deviate, the application needs to control the rotation angle of the pedal within a certain range, such as 0-10°. Correspondingly, the lifting range of the clamping assembly controlled by the angle rotation is 0-22.6mm. When the height adjustment range of the clamping assembly needs to be larger, the height can be adjusted by lifting the adjustment shell. In the application, the height controlled by the adjustment control is kept within the range of 0-22.6mm.

[0018] In a preferred technical solution of the utility model, the clamping assembly includes a lifting support block and a clamping member located on the top of the lifting support block, and the bottom of the lifting support block abuts against the pedal; the bottom of the lifting support block is a spherical structure, and a first spherical positioning groove is provided in the pedal.

[0019] The bottom of the lifting support block in the present application is set as a spherical structure that matches the first positioning groove in the pedal, ensuring that the lifting support block can fit the pedal accurately to avoid deviations during the synchronous rotation or synchronous lifting of the two. The top of the lifting support block in the present application is set with a clamping block for clamping the workpiece, and the lifting support block and the clamping piece are fixedly connected to achieve synchronous lifting.

[0020] In a preferred technical solution of the utility model, the bottom of the adjustment control is a spherical structure, and a second spherical positioning groove is provided in the pedal abutting against the adjustment control.

[0021] In the present application, the adjustment control unit can specifically be a nut, the bottom of the nut is designed as a spherical structure, a second spherical positioning groove is provided in the pedal, and the second spherical positioning groove is adapted to the spherical structure at the bottom of the nut to ensure that the two are precisely fitted to avoid position deviation between the two when the adjustment control unit presses the pedal, thereby ensuring the accuracy of the lifting and lowering position of the clamping assembly.

[0022] The second purpose of the utility model is to provide a lifting fixture, comprising the height-adjustable clamping device as described above, wherein two height-adjustable clamping devices are symmetrically arranged on the lifting fixture, and the two clamping devices are respectively used to clamp the two ends of the workpiece.

[0023] After the workpiece is clamped and hoisted, if the heights on both sides are uneven, the height of the clamping parts in one or both clamping devices can be adjusted through the control panel to achieve rapid leveling of the workpiece, thereby ensuring the subsequent processing accuracy of the workpiece.

[0024] The beneficial effects of the utility model are:

[0025] The utility model provides a height-adjustable clamping device, including a rotary adjusting member, the rotary adjusting member including a pedal and a fixed shaft located at the center of the pedal, the two sides of the pedal can rotate relative to the axis of the fixed shaft, one side of the pedal is connected to the adjusting control member, and the other side of the pedal is connected to the clamping assembly, and the clamping assembly is provided with a clamping member for fixing the workpiece. Since the position of the fixed shaft is fixed, the fixed shaft and the pedal together form a seesaw structure, when the adjusting control member presses one side of the pedal or moves away from the side of the pedal, the position and height of the clamping assembly will change, and the height of the clamping assembly can be accurately controlled by controlling the position of the adjusting control member, thereby achieving the height adjustment of the workpiece clamping position. The present application can avoid the defects of frequent debugging in the prior art and improve the efficiency and accuracy of the clamping device adjustment.

[0026] The utility model also provides a lifting fixture including the above-mentioned clamping device, the lifting fixture includes two clamping devices, and the two clamping devices are respectively used to clamp the two ends of the workpiece.

These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0040] Example 1

[0041] like Figure 1-Figure 8 As shown, a height-adjustable clamping device includes a rotating adjustment member, wherein the rotating adjustment member includes a pedal 112 and a fixed shaft 111 located at the center of the pedal, both sides of the pedal 112 can rotate relative to the axis of the fixed shaft 111, one side of the pedal 112 is connected to the adjustment control unit 12, and the other side of the pedal 112 is connected to the clamping assembly, and the clamping assembly is provided with a clamping member 13 for fixing the workpiece.

[0042] Since the position of the fixed shaft 111 is fixed, the fixed shaft 111 and the two sides of the pedal 112 together form a seesaw structure. When the adjustment control 12 presses one side 112 of the pedal or moves away from the side 112 of the pedal, the position and height of the clamping assembly will change. By controlling the position of the adjustment control 12, the height of the clamping assembly can be accurately controlled, thereby achieving adjustment of the height of the workpiece clamping position. The present application can avoid the defects of frequent debugging in the prior art and improve the efficiency and accuracy of adjustment of the clamping device.

[0043] In practical applications, the fixed shaft 111 is a shaft extending in the horizontal direction and fixed in position, and both sides of the fixed shaft 111 pedal 112 can be horizontal structures, or Figure 3 As shown, both sides of the pedal 112 are slightly inclined upward relative to the fixed shaft 111. The fixed shaft 111 and both sides of the pedal 112 are integrally formed to form a seesaw-like structure. Figure 3 As shown, when both sides of the pedal 112 are tilted upward relative to the fixed shaft 111, the up and down movement of both sides of the pedal 112 can be made more convenient. Since the lifting and lowering movements of both sides of the pedal 112 are opposite, that is, one side rises and the other side falls, if the pedal 112 is tilted upward, sufficient rising and falling space can be reserved for both sides of the pedal 112 to move.

[0044] It should be noted that in the present application, the rotation angles of both sides of the pedal 112 relative to the fixed axis 111 can be limited by structures such as blocking members or shells. According to the size of the rotating adjustment member, the rotation angle of the pedal 112 is limited, which can ensure that the clamping assembly rotates basically in the vertical direction, and avoid the clamping assembly from changing in the horizontal direction when clamping the workpiece, thereby affecting the clamping position of the workpiece. Specifically, when the distance between the side of the pedal 112 away from the fixed axis 111 and the fixed axis 111 is large, the rotation angle can be limited to be relatively large; when the distance between the side of the pedal 112 away from the fixed axis 111 and the fixed axis 111 is small, the rotation angle can be limited to be relatively small. A limiting structure such as a blocking member is set at the extreme position of the rotation angle to ensure that the rotation angle of the pedal 112 relative to the fixed axis 111 is limited to a preset range, so as to achieve position correction within the corresponding height range.

[0045] The limiting structure in the present application can be a blocking member arranged on the upper and lower sides of the pedal 112, such as a baffle or other structure; it can also be an adjusting shell 10 mounted on the outside of the rotating adjusting member, and the shell structure of the adjusting shell 10 can be used alone as a blocking member to limit the rotation of the pedal 112.

[0046] Example 2

[0047] like Figure 1-Figure 8As shown, a height-adjustable clamping device includes a rotating adjustment member, wherein the rotating adjustment member includes a pedal 112 and a fixed shaft 111 located at the center of the pedal, both sides of the pedal 112 can rotate relative to the axis of the fixed shaft 111, one side of the pedal 112 is connected to the adjustment control unit 12, and the other side of the pedal 112 is connected to the clamping assembly, and the clamping assembly is provided with a clamping member 13 for fixing the workpiece.

[0048] The present application also includes an adjustment housing 10 , wherein the adjustment housing 10 is provided with a hollow chamber, and the rotary adjustment member is located inside the hollow chamber.

[0049] The hollow chamber here refers to a space provided for accommodating a rotating adjustment member; specifically, the fixed shaft 111 can be fixed inside the adjustment housing 10. In actual operation, the adjustment housing 10 is fixedly mounted on the platform. Since the fixed shaft 111 is fixed relative to the adjustment housing 10, it can be ensured that the fixed shaft 111 is fixed relative to the platform, and both sides of the pedal 112 are raised and lowered under the action of the adjustment control 12. In the present application, the adjustment control 12 is used to control the position of the corresponding pedal 112. The pedals 112 are relatively arranged and rotate relatively. When the adjustment control 12 controls one end of the pedal 112 to rotate, the other end of the pedal 112 synchronously drives the clamping assembly to rotate. When the rotation angle is controlled within a small range, the rotation of the pedal 112 can be understood as lifting and lowering in the vertical direction.

[0050] The present application uses an adjustment shell 10 to wrap the rotating adjustment part, which can ensure that the rotating adjustment part acts as a whole, is easy to install and clamp, is suitable for various clamping occasions, expands the application scope of the clamping device, and facilitates the installation and disassembly of the clamping device.

[0051] The top of the adjusting housing 10 of the present application is provided with a first through hole 16 for the clamping assembly to extend out, and the top of the adjusting housing 10 is provided with a second through hole 17 for the adjusting control 12 to extend out.

[0052] In the present application, the bottom of the adjustment control 12 is set inside the adjustment housing 10, and the top is set outside the adjustment housing 10, so that it is convenient for the operator to press or lift the adjustment control 12. The adjustment control 12 is an active control component, and the clamping component is a passive lifting component. The operating end of the active control component is set outside the adjustment housing 10, which can be convenient for the operator to operate and can also be convenient for the operator to accurately adjust the lifting height. The bottom of the clamping component is set inside the adjustment housing 10, and the top is also set outside the adjustment. A clamping component 13 needs to be set on the top. The clamping component 13 is used to clamp the tooling. Specifically, it can be based on the processing requirements of the workpiece to ensure that the clamping component 13 exposes the surface to be processed of the workpiece when clamping the workpiece.

[0053] Furthermore, a third through hole 18 is provided on the side wall of the adjusting housing 10 of the present application, and the fastener 15 passes through the third through hole 18 and abuts against the side wall of the clamping assembly.

[0054] During the lifting and lowering adjustment of the clamping assembly, the fastener 15 is away from the clamping assembly, and at this time, the fastener 15 does not abut against the clamping assembly, and does not limit the position of the fastener 15. After the lifting position of the clamping assembly is determined, the fastening screw is tightened so that the fastening screw abuts against the clamping assembly to limit the position of the clamping assembly, ensuring that the height of the clamping assembly in the vertical direction is constant, and avoiding position deviation of the clamping assembly after leveling.

[0055] In order to avoid relative displacement between the fastener 15 and the clamping assembly, the present application may set the abutment surfaces of the clamping assembly and the fastener 15 to be mutually compatible inclined surfaces.

[0056] Specifically, the abutting surface of the clamping assembly can be set as a downward inclined surface, and the abutting surface of the fastener 15 can be set as an upward inclined surface. When the clamping assembly and the fastener 15 abut, the two abutting inclinations are just adapted. Since the clamping assembly is lifted and lowered in the vertical direction, in order to avoid relative displacement between the fastener 15 and the clamping assembly, the abutting surfaces of the two are set as inclined surfaces, and one is an upward inclined surface and the other is a downward inclined surface, which fit and abut in the vertical direction to avoid the clamping assembly and the fastener 15 from deviating in the vertical direction.

[0057] As a specific embodiment, the fastener 15 can be a fastening screw, one side of which is located outside the adjustment housing 10, and the other side of which extends into the adjustment housing 10 through the third through hole 18. The inner side wall of the third through hole 18 can be provided with an internal thread adapted to the fastening screw, and by tightening or loosening the fastening screw, the fastening screw is ensured to be away from the clamping assembly, or to abut against the clamping assembly, thereby achieving a limiting effect on the height-determined clamping assembly.

[0058] In order to avoid relative displacement between the clamping assembly and the fastening screw, the abutting surface of the clamping assembly is set as a downward inclined surface, and the abutting surface of the fastener 15 is set as an upward inclined surface. When the clamping assembly and the fastener 15 abut, the two abutting inclinations are just adapted. Alternatively, the abutting surface of the clamping assembly is set as an upward inclined surface, and the abutting surface of the fastener 15 is set as a downward inclined surface.

[0059] As another specific embodiment, the fastener 15 includes a top block and a nut. The top block passes through the third through hole 18. The nut is nested on the side of the top block away from the clamping assembly, and the nut is located outside the adjustment housing 10. By tightening or loosening the nut, the top block can be driven to move in a direction close to or away from the clamping assembly. Specifically, a limiting boss is provided inside the nut, and a limiting groove is provided outside the top block. The limiting boss and the limiting groove are adapted to be connected to ensure that the nut and the top block are fixed together, and the two can move forward or backward synchronously. The outer diameter of the top block is less than or equal to the inner diameter of the third through hole 18, and the inner diameter of the nut is greater than the inner diameter of the third through hole 18, ensuring that the nut is located outside the adjustment housing 10. One end of the top block is connected to the nut, and the other end is located inside the adjustment housing 10.

[0060] In order to avoid relative displacement between the clamping assembly and the fastening screw, the abutting surface of the clamping assembly is set as a downward inclined surface, and the abutting surface of the top block is set as an upward inclined surface. When the clamping assembly and the top block abut, the inclinations of the two abutments are just adapted. Alternatively, the abutting surface of the clamping assembly is set as an upward inclined surface, and the abutting surface of the top block is set as a downward inclined surface.

[0061] like Figure 1-Figure 4 As shown, the rotary adjustment member in the present application is a symmetrically arranged structure, wherein an arc-shaped protrusion is arranged at the center of the pedal 112, and the pedal 112 and the arc-shaped protrusion can be integrally formed by injection molding. A through hole for the fixed shaft 111 to pass through is arranged in the arc-shaped protrusion, and the fixed shaft 111 passes through the through hole and is fixed together with the arc-shaped protrusion. At the same time, the two ends of the fixed shaft 111 are fixed in the two opposite inner side walls of the adjustment housing 10; in this way, it can be ensured that the fixed shaft 111 is fixedly connected to the arc-shaped protrusion and the adjustment housing at the same time, and the rotary adjustment member is fixed inside the adjustment housing 10.

[0062] Continue reading Figure 1-Figure 4 When the adjustment shell 10 is placed horizontally, the fixed axis 111 is an axis extending in the horizontal direction, and the two sides of the pedal 112 are inclined plates slightly inclined upward relative to the horizontal plane. The inclined plates can be set to an arc-shaped structure and smoothly dock with the arc-shaped protrusion. The pedal 112 is symmetrically arranged relative to the fixed axis 111, that is, the shape, size and upward angle of the two are the same. When the rotary adjustment member is installed inside the adjustment shell 10, the bottom of the arc-shaped protrusion abuts against the inner bottom of the adjustment shell 10. Since the two sides of the pedal 112 are an upwardly inclined structure, if the upward inclination angle is x, the two sides of the pedal 112 can rotate around the axis of the fixed axis 111 within the angle range of 0-x.

[0063] like Figure 5As shown, the fixed shaft 111 is fixed to the inner bottom of the adjusting housing 10; the angle of rotation of the two sides of the pedal 112 around the axis of the fixed shaft 111 is 0-10°. When the size of the pedal 112 is determined, the rotation angle can drive the lifting height of the clamping assembly to be 0-22.6mm.

[0064] In order to ensure that the position of the clamping assembly in the horizontal direction does not deviate, the present application needs to control the rotation angle of the pedal 112 within a certain range, such as within the range of 0-10°. Correspondingly, the lifting range of the clamping assembly controlled by the angle rotation is 0-22.6mm. When the height adjustment range of the clamping assembly needs to be larger, the height can be adjusted by lifting the adjustment housing 10. In the present application, the height controlled by the adjustment control 12 is kept within the range of 0-22.6mm.

[0065] As a specific embodiment, the clamping assembly includes a lifting support block 14 and a clamping member 13 located on the top of the lifting support block 14, and the bottom of the lifting support block 14 abuts against the pedal 112; the bottom of the lifting support block 14 is a spherical structure, and a first spherical positioning groove is provided in the pedal 112.

[0066] In the present application, the bottom of the lifting support block 14 is set to a spherical structure that matches the first positioning groove in the pedal 112, ensuring that the lifting support block 14 can accurately fit the pedal 112 to avoid deviations during the synchronous rotation or synchronous lifting of the two. In the present application, a clamping block for clamping a workpiece is set on the top of the lifting support block 14, and the lifting support block 14 and the clamping member 13 are fixedly connected to achieve synchronous lifting.

[0067] The bottom of the adjustment control 12 is a spherical structure, and a second spherical positioning groove is provided in the pedal 112 abutting against the adjustment control 12 .

[0068] In the present application, the adjustment control 12 can specifically be a nut, the bottom of the nut is designed as a spherical structure, a second spherical positioning groove is provided in the pedal 112, and the second spherical positioning groove is adapted to the spherical structure at the bottom of the nut to ensure that the two are precisely fitted to avoid position deviation between the two when the adjustment control 12 presses the pedal 112, thereby ensuring the accuracy of the lifting and lowering position of the clamping assembly.

[0069] Example 3

[0070] like Figure 6 As shown, this embodiment provides a lifting fixture, including two symmetrically arranged height-adjustable clamping devices, and the two clamping devices are respectively used to clamp two ends of a workpiece.

[0071] The two clamping devices have the same structure and are symmetrically arranged to clamp the two ends of the workpiece.

[0072] Specifically, the height-adjustable clamping device includes an adjusting shell 10 and a rotating adjusting member located inside the adjusting shell 10, wherein the rotating adjusting member includes a pedal 112 and a fixed shaft 111 located at the center of the pedal, and both sides of the pedal 112 can rotate relative to the axis of the fixed shaft 111. One side of the pedal 112 is connected to the adjustment control unit 12, and the other side of the pedal 112 is connected to the clamping assembly, wherein the clamping assembly is provided with a clamping member 13 for fixing the workpiece.

[0073] The top of the adjustment housing 10 is provided with a first through hole 16 for the clamping assembly to extend out, and the top of the adjustment housing 10 is provided with a second through hole 17 for the adjustment control 12 to extend out. The side wall of the adjustment housing 10 is provided with a third through hole 18, and the fastener 15 passes through the third through hole 18 and abuts against the side wall of the clamping assembly. At the same time, the abutting surfaces of the clamping assembly and the fastener 15 are mutually adapted inclined surfaces.

[0074] The rotary adjustment member in the present application is a symmetrically arranged structure, wherein an arc-shaped protrusion is arranged at the center of the pedal 112, and the pedal 112 and the arc-shaped protrusion can be integrally formed by injection molding. A through hole is arranged in the arc-shaped protrusion for the fixed shaft 111 to pass through, and the fixed shaft 111 passes through the through hole and is fixed together with the arc-shaped protrusion. At the same time, the two ends of the fixed shaft 111 are fixed in the two opposite inner side walls of the adjustment housing 10; in this way, it can be ensured that the fixed shaft 111 is fixedly connected to the arc-shaped protrusion and the adjustment housing at the same time, and the rotary adjustment member is fixed inside the adjustment housing 10.

[0075] Continue reading Figure 1-Figure 4 When the adjustment shell 10 is placed horizontally, the fixed axis 111 is an axis extending in the horizontal direction, and the two sides of the pedal 112 are inclined plates slightly inclined upward relative to the horizontal plane. The inclined plates can be set to an arc-shaped structure and smoothly dock with the arc-shaped protrusion. The pedal 112 is symmetrically arranged relative to the fixed axis 111, that is, the shape, size and upward angle of the two are the same. When the rotary adjustment member is installed inside the adjustment shell 10, the bottom of the arc-shaped protrusion abuts against the inner bottom of the adjustment shell 10. Since the two sides of the pedal 112 are an upwardly inclined structure, if the upward inclination angle is x, the two sides of the pedal 112 can rotate around the axis of the fixed axis 111 within the angle range of 0-x.

[0076] The clamping assembly includes a lifting support block 14 and a clamping member 13 located on the top of the lifting support block 14. The bottom of the lifting support block 14 abuts against the pedal 112. The bottom of the lifting support block 14 is a spherical structure, and a first spherical positioning groove is provided in the pedal 112. The bottom of the adjustment control 12 is a spherical structure, and a second spherical positioning groove is provided in the pedal 112 abutting against the adjustment control 12.

[0077] In this embodiment, the clamping member 13 is specifically a clamping screw, and the lifting support block 14 is an L-shaped structure. The bottom of the L-shaped lifting support block 14 is a spherical structure, and the top is a vertical bending structure, and the bending structure includes a horizontal bending plate extending in the horizontal direction, and a vertical bending plate extending in the vertical direction. The horizontal bending plate and the vertical bending plate are both provided with a fastening track for fixing the clamping screw. In this embodiment, the clamping screw is fixed in the horizontal bending plate, and the horizontal bending plate extends in a direction away from the fixed axis 111. The clamping screw runs through the top of the horizontal bending plate to the bottom, and the end of the clamping screw is used to fix the workpiece.

[0079] like Figure 7 As shown, this embodiment provides a lifting fixture, including two symmetrically arranged height-adjustable clamping devices, and the two clamping devices are respectively used to clamp two ends of a workpiece.

[0080] The two clamping devices have the same structure and are symmetrically arranged to clamp the two ends of the workpiece.

[0081] Specifically, the height-adjustable clamping device includes an adjusting shell 10 and a rotating adjusting member located inside the adjusting shell 10, wherein the rotating adjusting member includes a pedal 112 and a fixed shaft 111 located at the center of the pedal, and both sides of the pedal 112 can rotate relative to the axis of the fixed shaft 111. One side of the pedal 112 is connected to the adjustment control unit 12, and the other side of the pedal 112 is connected to the clamping assembly, wherein the clamping assembly is provided with a clamping member 13 for fixing the workpiece.

[0082] The top of the adjustment housing 10 is provided with a first through hole 16 for the clamping assembly to extend out, and the top of the adjustment housing 10 is provided with a second through hole 17 for the adjustment control 12 to extend out. The side wall of the adjustment housing 10 is provided with a third through hole 18, and the fastener 15 passes through the third through hole 18 and abuts against the side wall of the clamping assembly. At the same time, the abutting surfaces of the clamping assembly and the fastener 15 are mutually adapted inclined surfaces.

[0083] The rotary adjustment member in the present application is a symmetrically arranged structure, wherein an arc-shaped protrusion is arranged at the center of the pedal 112, and the pedal 112 and the arc-shaped protrusion can be integrally formed by injection molding. A through hole is arranged in the arc-shaped protrusion for the fixed shaft 111 to pass through, and the fixed shaft 111 passes through the through hole and is fixed together with the arc-shaped protrusion. At the same time, the two ends of the fixed shaft 111 are fixed in the two opposite inner side walls of the adjustment housing 10; in this way, it can be ensured that the fixed shaft 111 is fixedly connected to the arc-shaped protrusion and the adjustment housing at the same time, and the rotary adjustment member is fixed inside the adjustment housing 10.

The inclined plates can be set to an arc-shaped structure and smoothly dock with the arc-shaped protrusion. The pedal 112 is symmetrically arranged relative to the fixed axis 111, that is, the shape, size and upward angle of the two are the same. When the rotary adjustment member is installed inside the adjustment shell 10, the bottom of the arc-shaped protrusion abuts against the inner bottom of the adjustment shell 10. Since the two sides of the pedal 112 are an upwardly inclined structure, if the upward inclination angle is x, the two sides of the pedal 112 can rotate around the axis of the fixed axis 111 within the angle range of 0-x.

The bottom of the L-shaped lifting support block 14 is a spherical structure, and the top is a vertical bending structure, and the bending structure includes a horizontal bending plate extending in the horizontal direction, and a vertical bending plate extending in the vertical direction. The horizontal bending plate and the vertical bending plate are both provided with a fastening track for fixing the clamping screw. In this embodiment, the clamping screw is fixed in the horizontal bending plate, and the horizontal bending plate extends in a direction away from the fixed axis 111. The clamping screw runs through the bottom of the horizontal bending plate to the top, and the upper end of the clamping screw is used to fix the workpiece. Figure 7 As shown, the clamping screw finally formed fixes the bottom of the workpiece, thereby lifting the workpiece and facilitating the processing of the side and top surfaces of the workpiece.
