Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, and in particular to a clamping fixture that integrates clamping and positioning. Background Technology
[0002] In the processing of some plate-shaped workpieces, it is necessary to position and fix the workpiece before processing and manufacturing using appropriate equipment. Positioning is achieved using a cylinder and a positioning block controlled by the cylinder, while clamping is also achieved by the cylinder driving the clamping block to clamp the workpiece. For example, the positioning fixture and positioning and docking method for ignition and extinguishing arc plates disclosed in patent publication number CN111266699B includes a pair of positioning clamping mechanisms and a clamping mechanism, both of which are driven by cylinders and are located in different positions.
[0003] As can be seen, conventional positioning and clamping structures are arranged separately, and can only position or clamp a certain position of the workpiece. However, for special workpieces, such as a certain position in the lithium battery liquid cooling plate designed by our company that requires both positioning and clamping, conventional fixture structures are difficult to meet application requirements due to their dispersed nature.
[0004] There are also fixtures that combine positioning and clamping functions. For example, patent publication number CN220592079U discloses a highly adaptable universal positioning tooling fixture. A cylinder drives a clamping block to clamp and fix the side of the workpiece, and the top of the clamping block, through the coordinated application of a series of components, clamps and fixes the top of the workpiece. It can simultaneously position and clamp a certain position of the workpiece. However, manual clamping is cumbersome and has weak reliability. Summary of the Invention
[0005] To address the problem that conventional fixtures cannot simultaneously accommodate positioning and clamping, this invention provides a fixture that integrates clamping and limiting functions. This fixture combines positioning and clamping structures into one compact design, providing both positioning and clamping functions. It uses a cylinder as the driving force to achieve automated operation and improve clamping reliability.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fixture that integrates clamping and limiting functions includes a limiting component and a clamping component. The limiting component includes a limiting bracket, a limiting cylinder, and a limiting plate. The limiting cylinder is installed above the limiting bracket to facilitate support of the limiting cylinder. The limiting plate is connected to the piston rod of the limiting cylinder to facilitate control of the movement of the limiting plate. The limiting plate slides horizontally above the limiting bracket. The pressing member is arranged inside the limiting bracket. The pressing member includes a pressing seat, a mounting bracket, a pressing cylinder, and a clamping jaw. The mounting bracket is arranged on one side of the pressing seat. The pressing cylinder is hinged below the mounting bracket to facilitate slight swinging of the pressing cylinder. The clamping jaw is hinged above the mounting bracket. One end of the clamping jaw is hinged to the piston rod of the pressing cylinder, and the other end of the clamping jaw presses the workpiece. The clamping jaw extends upward beyond the limiting plate.
[0007] Further, the limiting bracket includes a horizontal frame and a supporting bent plate. The horizontal frame is bent into a "U" shape and is horizontally arranged. The supporting bent plate is centrally arranged below the horizontal frame. This improves the reliability of supporting the limiting cylinder.
[0008] Further, the limiting cylinder is arranged on the horizontal frame. The limiting cylinder is a double-rod cylinder with stable operation. The cross-section of the limiting plate is in a "T" shape, and a rectangular relief hole is provided on the limiting plate to facilitate providing a certain space for the clamping jaw to pass through. After the relief hole and the limiting plate are connected and combined, the cross-section is in a "hui" (Chinese character for "return") shape. The clamping jaw extends upward beyond the relief hole to the upper plane of the limiting plate.
[0009] Further, the cross-section of the pressing seat is in a "U" shape. The pressing seats are arranged between the two sides of the horizontal frame and are vertically arranged. The mounting bracket is bolted to one side of the pressing seat, and the cross-section of the mounting bracket is in an "a" shape.
[0010] Further, a cylinder seat is provided on the pressing cylinder. The pressing cylinder is hinged to the lower part of the mounting bracket through the cylinder seat. The piston rod of the pressing cylinder extends upward beyond the cylinder seat and is bolted to a hinge block. The cross-section of the hinge block is in a "U" shape, and the hinge block is hinged to one end of the clamping jaw.
[0011] Further, two connecting rods are hinged above the mounting bracket. The two connecting rods are arranged at intervals. The clamping jaw is arranged between the upper ends of the two connecting rods. A pin shaft is passed through the middle parts of the two connecting rods and the clamping jaw. The number of the pin shafts is two. The cross-section of the clamping jaw is in a "T" shape, which increases the contact area with the workpiece.
[0012] Through the above technical solutions, the beneficial effects of the present utility model are as follows: The structure of the present utility model is reasonably designed. For the special position of the workpiece, there are both positioning requirements and pressing requirements, and the entire fixture tooling can be applicable. The limiting member and the pressing member are combined together to achieve a compact structural layout. The limiting cylinder drives the limiting plate to press against the edge of the workpiece to facilitate positioning it, and the pressing cylinder realizes the pressing of the workpiece through the connecting rod structure to facilitate pressing it. Thus, the positioning and pressing of a certain position of the workpiece can be achieved simultaneously, and the positioning and pressing requirements of the workpiece can be quickly met, and the actual application effect is good.

[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: like Figures 1-5 As shown, the fixture integrates clamping and limiting, including limiting component 1 and clamping component 2. Both limiting component 1 and clamping component 2 are installed on a certain carrier, which can be a welding table 3. The limiting component 1 and clamping component 2 can be fixed at the edge of the welding table 3.
[0020] The limiting component 1 is used for positioning the workpiece and limiting its horizontal movement. The limiting component 1 includes a limiting bracket 4, a limiting cylinder 5, and a limiting plate 6. The limiting bracket 4 is fixed to the edge of the welding table 3. The limiting bracket 4 includes a horizontal frame 41 and a supporting bent plate 42. The horizontal frame 41 is bent into a "U" shape and is arranged horizontally. Both ends of the horizontal frame 41 are connected and fixed to the edge of the welding table 3. The supporting bent plate 42 is centrally located below the horizontal frame 41. The supporting bent plate 42 is a bent plate body. The upper end of the supporting bent plate 42 is connected and fixed to the horizontal frame 41, and the lower end is connected and fixed to the welding table 3.
[0021] A limit cylinder 5 is arranged above the limit bracket 4, that is, the limit cylinder 5 is arranged on the horizontal bracket 41. The limit cylinder 5 is a double-rod cylinder. A limit plate 6 is connected to the piston rod of the limit cylinder 5. The cross-section of the limit plate 6 is in the shape of a "T". The limit plates 6 are arranged horizontally. Under the operation of the limit cylinder 5, the limit plate 6 can be driven to slide horizontally above the limit bracket 4. A rectangular relief hole 7 is formed in the limit plate 6. After the relief hole 7 and the limit plate 6 are connected and combined, the cross-section is in the shape of a "hui" character.
[0022] The pressing member 2 is arranged inside the limit bracket 4 to achieve the compactness of the design structure. The pressing member 2 is used to press the workpiece from above the workpiece. The pressing member 2 includes a pressing seat 8, a mounting bracket 9, a pressing cylinder 10 and a clamping jaw 11. The cross-section of the pressing seat 8 is in the shape of a "凵". The pressing seats 8 are arranged between both sides of the horizontal bracket 41. The pressing seats 8 are arranged vertically. The pressing seat 8 is fixedly connected to the edge of the welding seat.
[0023] A mounting bracket 9 is arranged on one side of the pressing seat 8. Specifically, the mounting bracket 9 is bolted to one side of the pressing seat 8. The cross-section of the mounting bracket 9 is in the shape of a "ㅏ". The pressing cylinder 10 is hinged below the mounting bracket 9. Specifically, a cylinder seat 12 is arranged on the pressing cylinder 10. The pressing cylinder 10 and the cylinder seat 12 are fixed. The cylinder seat 12 is a plate body. The pressing cylinder 10 is hinged to the lower part of the mounting bracket 9 through the cylinder seat 12. Therefore, the entire pressing cylinder 10 can swing relative to the mounting bracket 9. The piston rod of the pressing cylinder 10 extends upward out of the cylinder seat 12, and the cylinder seat 12 does not interfere with the operation of the piston rod. There is a gap between the pressing cylinder 10 and the support bent plate 42, which does not interfere with the slight swing of the pressing cylinder 10.
[0024] The clamping jaw 11 is hinged above the mounting bracket 9. Specifically, two connecting rods 13 are hinged above the mounting bracket 9. The two connecting rods 13 are arranged at intervals. The two connecting rods 13 are equivalent to clamping the upper end of the mounting bracket 9. The clamping jaw 11 is arranged between the upper ends of the two connecting rods 13. A pin shaft 14 is arranged through the middle parts of the two connecting rods 13 and the clamping jaw 11. The number of the pin shafts 14 is two. Therefore, there is no relative swing between the clamping jaw 11 and the connecting rods 13. After the clamping jaw 11 and the connecting rods 13 are connected, the whole can swing relative to the mounting bracket 9 to achieve the hinged installation of the clamping jaw 11.
[0025] In order to drive the clamping jaw 进行摆动, one end of the clamping jaw 11 is hinged to the piston rod of the pressing cylinder 10. Specifically, after the piston rod of the pressing cylinder 10 extends upward out of the cylinder seat 12, it is bolted to a hinge block 15. The cross-section of the hinge block 15 is in the shape of a "凵". The hinge block 与压爪11一端铰接. After the pressing cylinder 10 operates, it can control the clamping jaw 11 to swing.
[0026] The pressure claw 11 has a "T" shaped cross-section. The other end of the pressure claw 11 passes over the limiting plate 6 and clamps the workpiece. The pressure claw 11 extends upwards beyond the limiting plate 6, that is, it extends upwards past the clearance hole 7 and above the upper plane of the limiting plate 6. This prevents the limiting plate 6 from interfering with the movement of the pressure claw 11. Simultaneously, the clearance hole 7 has a certain size, allowing the pressure claw 11 to move without affecting the operation of the limiting plate 6 itself. After the end of the pressure claw 11 clamps the workpiece, the pressure claw 11 contacts the workpiece surface.
[0027] The principle of this invention is as follows: The limiting plate 6 and the clamping component 2 are installed together at the designated edge position of the welding table 3. After installation, the lithium battery liquid cooling plate 16 workpiece can be positioned and clamped at the designated position. After the limiting cylinder 5 is activated, it drives the limiting plate 6 to move horizontally until the limiting plate 6 abuts against the edge of the workpiece. After the clamping cylinder 10 is activated, it drives the clamping claw 11 to swing downward, and the clamping claw 11 eventually becomes parallel to the workpiece, thereby causing the downward pressure to be evenly distributed on the contact surface between the clamping claw 11 and the workpiece. In this way, the positioning and clamping structures are combined in a compact structure, realizing the side clamping and top clamping of the workpiece at the designated position, meeting the requirements of practical applications.
[0028] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
