Description

quick limit clamp Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a quick-release clamping fixture. Background Technology

[0002] In machining processes, fixtures are often used to position and clamp workpieces to ensure machining accuracy and operational safety. In traditional technology, fixtures are generally used to position and clamp workpieces by holding their outer circumferential surfaces. However, this method of using fixtures to hold the outer circumferential surfaces of workpieces results in the workpiece being obstructed by the fixtures, requiring the machining equipment to clamp the workpiece multiple times during the machining process to avoid the surface of the workpiece being held by the fixtures. This leads to the technical problem of low machining efficiency on the outer circumferential surfaces of workpieces. Summary of the Invention

[0003] Therefore, it is necessary to provide a quick-closing fixture to address the technical problem of low machining efficiency on the outer periphery of the workpiece.

[0004] A quick-release clamp includes: a fixed base, a pressure head, a driving component, and a positioning component. The fixed base has a placement surface and a movable hole penetrating the placement surface. The pressure head is spaced apart from the side of the fixed base near the placement surface. The driving component is connected to the side of the fixed base away from the placement surface and passes through the movable hole to connect with the pressure head. The driving component drives the pressure head to move closer to or away from the placement surface. The positioning component is disposed between the pressure head and the placement surface and has a clearance opening for the driving component to move through. The positioning component is supported by the pressure head.

[0005] In one embodiment, the number of driving elements is multiple, and the number of movable holes and positioning elements is the same as the number of driving elements.

[0006] In one embodiment, the clearance opening is U-shaped.

[0007] In one embodiment, the positioning member is provided with a guide opening that connects to the avoidance opening, and the guide opening gradually expands in a direction away from the avoidance opening.

[0008] In one embodiment, the number of driving members is multiple, the number of movable holes is the same as the number of driving members, and the positioning member is provided with clearance openings for the multiple driving members to move through.

[0009] In one embodiment, the positioning member further includes a positioning groove disposed on the side of the positioning member close to the placement surface.

[0010] In one embodiment, the positioning element is further provided with a guide opening that gradually widens toward the placement surface.

[0011] In one embodiment, the number of positioning elements is multiple.

[0012] In one embodiment, the fixing base includes a support plate and support blocks. The support plate has the placement surface and the movable hole. There are two support blocks, which are connected to the end of the support plate opposite to the placement surface. Each support block and the support plate form a receiving groove communicating with the movable hole. Part of the driving component is disposed in the receiving groove.

[0013] In one embodiment, the driving component includes a cylinder and a piston rod. The cylinder is connected to the side of the fixed seat opposite to the placement surface and drives the piston rod to move through the movable hole. The piston rod is connected to the pressure head. The side of the fixed seat opposite to the placement surface is provided with a receiving groove to accommodate the cylinder.

[0014] The beneficial effects of the quick-release clamp provided in this application are as follows: A driving component drives the pressure head to move closer to or further away from the placement surface. A positioning component is positioned between the pressure head and the placement surface, allowing the pressure head to hold the workpiece. The workpiece is placed on the placement surface, and the positioning component is positioned between the pressure head and the workpiece through a clearance opening. The positioning component provides initial positioning of the workpiece. Then, the driving component drives the pressure head downwards, using the force applied by the pressure head to the positioning component to clamp the workpiece between the positioning component and the placement surface. This clamping method eliminates the need to clamp the outer circumferential surface of the workpiece. Instead, the pressure head and the positioning component work together to clamp the workpiece vertically, avoiding obstruction of the workpiece's outer circumferential surface by the clamp. This eliminates the need for multiple clamping operations when processing the outer circumferential surface of the workpiece, thereby improving the processing efficiency of the workpiece's outer circumferential surface.

[0032] Example 1:

[0033] As shown in Figures 1 to 3, this is the quick-release clamp 100 of this utility model.

[0034] As shown in Figures 1 and 2, the quick-release clamp 100 includes: a fixed base 10, a pressure head 20, a driving member 30, and a positioning member 40a. The fixed base 10 has a placement surface 11 and a movable hole 12 penetrating the placement surface 11. The pressure head 20 is spaced apart from the side of the fixed base 10 near the placement surface 11. The driving member 30 is connected to the side of the fixed base 10 away from the placement surface 11 and passes through the movable hole 12 to connect with the pressure head 20. The driving member 30 drives the pressure head 20 to move closer to or away from the placement surface 11. The positioning member 40a is disposed between the pressure head 20 and the placement surface 11 and has a clearance opening 41 for the driving member 30 to move through. The positioning member 40a is supported by the pressure head 20. The driving member 30 drives the pressure head 20 to move closer to or away from the placement surface 11. The positioning member 40a is disposed between the pressure head 20 and the placement surface 11 to support the pressure head 20. The workpiece 200 is placed on the placement surface 11 by the pressure head 20 abutting. The positioning member 40a is placed between the pressure head 20 and the workpiece 200 through the clearance opening 41. The positioning member 40a initially positions the workpiece 200. Then, the driving member 30 drives the pressure head 20 to move downward. The force applied by the pressure head 20 to the positioning member 40a clamps the workpiece 200 between the positioning member 40a and the placement surface 11. This clamping method does not require clamping the outer peripheral surface of the workpiece 200. Instead, the workpiece 200 is clamped in the vertical direction by the cooperation of the pressure head 20 and the positioning member 40a, and by the positioning member 40a and the placement surface 11. This avoids the obstruction of the workpiece 200's outer peripheral surface by the fixture, so that the processing equipment does not need to clamp multiple times when processing the outer peripheral surface of the workpiece 200, thereby improving the processing efficiency of the outer peripheral surface of the workpiece 200.

[0035] The quick-stop clamp 100 described above will be further explained below with reference to Figures 1 to 3.

[0036] As shown in Figure 2, the fixed base 10 includes a support plate 13 and support blocks 14. The support plate 13 has a placement surface 11 and a movable hole 12. There are two support blocks 14, which are connected to the end of the support plate 13 away from the placement surface 11. Each support block 14 and the support plate 13 form a receiving groove 15 that communicates with the movable hole 12. Some of the driving components 30 are disposed in the receiving groove 15. The setting of the receiving groove 15 provides installation space for the driving components 30, so that the driving components 30 can be installed more compactly on the fixed base 10, reducing the overall volume of the fixture and saving installation space. At the same time, the receiving groove 15 can play a certain protective role for the driving components 30, preventing the driving components 30 from being exposed to the outside and subjected to external collisions or contamination, thereby extending the service life of the driving components 30.

[0037] Specifically, as shown in Figure 2, the driving component 30 includes a cylinder body 31 and a piston rod 32. The cylinder body 31 is connected to the side of the fixed seat 10 opposite to the placement surface 11, and drives the piston rod 32 to move through the movable hole 12. The piston rod 32 is connected to the pressure head 20. The side of the fixed seat 10 opposite to the placement surface 11 is provided with a receiving groove 15 to accommodate the cylinder body 31. The driving method using the cylinder body 31 and the piston rod 32 can provide a stable and controllable driving force, realizing the rapid movement and precise positioning of the pressure head 20. The receiving groove 15 accommodates the cylinder body 31, making the installation of the driving component 30 more stable, reducing the vibration of the driving component 30 during operation, and ensuring the smoothness of the driving process. At the same time, this structural design facilitates the replacement and maintenance of the driving component 30, thereby improving the practicality and reliability of the fixture.

[0038] To enhance the positioning effect of the fixture on the workpiece 200, as shown in Figures 1 and 2, there are multiple driving components 30. The number of movable holes 12 and positioning components 40a is the same as the number of driving components 30. By driving the pressure head 20 simultaneously with multiple driving components 30, the driving force on the pressure head 20 is more uniform, thereby enabling more stable clamping of the workpiece 200 and preventing the workpiece 200 from shifting during processing, thus achieving the purpose of enhancing the positioning effect of the fixture on the workpiece 200.

[0039] To improve the placement efficiency of the positioning component 40a, as shown in Figure 3, the clearance opening 41 is U-shaped. The U-shaped clearance opening 41 makes it easier for the driving component 30 to pass through the positioning component 40a, increasing the placement convenience of the positioning component 40a and achieving the purpose of improving the placement efficiency of the positioning component 40a.

[0040] To improve the assembly efficiency of the fixture, as shown in Figure 3, the positioning member 40a is provided with a guide port 42 that connects to the clearance port 41. The guide port 42 gradually expands in the direction away from the clearance port 41. The setting of the guide port 42 can guide the driving member 30 to insert into the clearance port 41 of the positioning member 40a. The flared structure of the guide port 42 makes it easy for the driving member 30 to quickly align with the clearance port 41, reducing the difficulty of installation and debugging, and achieving the purpose of improving the assembly efficiency of the fixture.

[0041] To clamp the workpiece 200 more evenly and reduce the manufacturing cost of the fixture, as shown in Figures 1 and 2, there are multiple driving components 30, and the number of movable holes 12 is the same as the number of driving components 30. The positioning component 40a is provided with a clearance opening 41 for multiple driving components 30 to pass through. Multiple driving components 30 are connected to the pressure head 20 through corresponding movable holes 12, and can jointly drive the pressure head 20 to move, so that the pressure head 20 is subjected to uniform force during movement, ensuring that the pressure head 20 is parallel to the placement surface 11, thereby clamping the workpiece 200 evenly. The clearance opening 41 on the positioning component 40a can allow multiple driving components 30 to pass through at the same time, which simplifies the structural design of the positioning component 40a, reduces the number of positioning components 40a, and achieves the purpose of reducing the manufacturing cost of the fixture.

[0042] To improve the machining quality of workpiece 200, as shown in Figure 3, positioning member 40a also includes positioning groove 43. Positioning groove 43 is located on the side of positioning member 40a near placement surface 11. The positioning groove 43 can be matched with the specific structure of workpiece 200, such as the groove on workpiece 200, so as to more accurately position workpiece 200. Through the cooperation between positioning groove 43 and workpiece 200, the horizontal movement of workpiece 200 can be restricted, the positioning accuracy of workpiece 200 can be improved, and the position of workpiece 200 can be kept stable during the machining process, thereby achieving the purpose of improving the machining quality of workpiece 200.

[0043] As shown in Figure 3, the positioning component 40a is also provided with a guide opening 44. The guide opening 44 gradually widens towards the placement surface 11. The guide opening 44 is mainly used to guide the workpiece 200. When the workpiece 200 is placed on the placement surface 11, the flared structure of the guide opening 44 can guide the workpiece 200 to accurately enter the positioning position, reducing the difficulty for workers to place the workpiece 200 and improving clamping efficiency. At the same time, the guide opening 44 can also provide a certain degree of protection for the edges of the workpiece 200, preventing the workpiece 200 from colliding with the positioning component 40a during placement and causing damage.

[0044] Example 2:

[0045] As shown in Figure 4, this is another quick-closing fixture 100 of the present invention. The difference between it and the quick-closing fixture 100 shown in Embodiment 1 is that there are multiple positioning elements 40b. Each positioning element 40b is arranged in a disc shape. Multiple positioning elements 40b can be distributed at different positions of the workpiece 200 to provide multi-point positioning and support for the workpiece 200. This better adapts to workpieces 200 of different shapes and sizes, improves the versatility of the fixture, and prevents the workpiece 200 from shaking or deforming during processing, thereby achieving the purpose of providing safety and processing accuracy for the workpiece 200 during processing.

[0046] When using the quick-release clamp 100 provided in this application: the workpiece 200 is placed on the placement surface 11 of the support plate 13. The driving member 30 passes through the positioning groove 43 and guide port 44 of the positioning member 40 to place the positioning member 40 on the workpiece 200 for initial positioning. Then, the driving member 30 works, the piston rod 32 extends, and drives the pressure head 20 to move downward. The force applied by the pressure head 20 to the positioning member 40 clamps the workpiece 200 between the positioning member 40 and the placement surface 11. Since the clamp clamps the workpiece 200 from top to bottom through the positioning member 40 and the placement surface 11, the outer peripheral surface of the workpiece 200 is not effectively clamped. Therefore, the processing equipment can continuously process the outer peripheral surface of the workpiece 200 without multiple clamping, thereby improving the processing efficiency of the outer peripheral surface of the workpiece 200.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
