[0043] Embodiment 1:

[0044] See also Figure 1-Figure 4 The present application provides a quickly detachable modular clamp, including a clamping seat 1, a fixed clamp 2, a movable clamp 3, and a locking bolt 4; the bottom of the clamping seat 1 is cylindrical, and the top is quadrangular prism-shaped. The top of the clamping seat 1 is constructed with a clamping groove 101, and the clamping groove 101 runs through the front and rear side surfaces of the clamping seat 1; the right side of the clamping groove 101 is provided with a fixed clamp 2. Specifically, after the bolt passes through the fixed clamp 2 from top to bottom, it is screwed with the clamping seat 1, and then the fixed clamp 2 is detachably installed on the clamping seat 1. The installation and disassembly of the fixed clamp 2 are convenient, which is convenient for the staff to perform subsequent maintenance and maintenance of the fixed clamp 2; the right side surface of the fixed clamp 2 abuts against the right side surface of the clamping groove 101, and the force applied to it when clamping the workpiece is provided through the side wall of the clamping groove 101, so as to reduce the shear force applied to the bolt, which is beneficial to improving the service life of the clamp and at the same time ensuring that the corresponding bolt can be removed smoothly when the fixed clamp 2 is disassembled. In some specific embodiments, a boss is provided on the right side of the clamping groove 101, and the fixed clamp 2 is fixedly installed on the boss. The fixed clamp 2 is made into a smaller volume and its top surface can still reach the set height, which is beneficial to reducing the overall volume of the fixed clamp 2 and reducing the replacement cost of the fixed clamp 2.

[0045] A movable jaw 3 is provided on the left side of the clamping groove 101, and the left end portion of the movable jaw 3 is movably connected to the clamping groove 101, and the right end portion of the movable jaw 3 is tilted upward, and the workpiece clamping position is set between the fixed jaw 2 and the movable jaw 3. When in use, the workpiece is placed at the workpiece clamping position, that is, between the fixed jaw 2 and the movable jaw 3, and then the right end of the movable jaw 3 is pressed down, and the right end of the movable jaw 3 moves to the lower right. This action can be decomposed into two, one is horizontally to the right, close to the fixed jaw 3, so as to clamp the workpiece, and the other is vertically downward, pressing the workpiece tightly on the fixture to ensure that the workpiece does not shake during the processing, which is conducive to the smooth progress of the workpiece processing process.

[0046] In this embodiment, the left end of the movable jaw 3 is in an arc shape, and the left end of the movable jaw 3 is respectively in contact with the side wall and the bottom surface of the clamping groove 101, forming a limit on the left end of the movable jaw 3, so that when the right end of the movable jaw 3 is pressed down, the left end of the movable jaw 3 will not move leftward or downward, but rotate at the original position, that is, when the right end of the movable jaw 3 is pressed down, the movable jaw 3 as a whole rotates clockwise with its left end as the center point. In some specific embodiments, the left end of the movable jaw 3 is hinged to the clamping groove 101 using a hinge shaft, which can also achieve the purpose of clamping the workpiece.

[0047] In this embodiment, the right end of the movable jaw 3 is pressed down by the locking bolt 4. Specifically, the movable jaw 3 is configured with a first through hole 301, and the bottom surface of the clamping groove 101 is provided with a first threaded hole 102 corresponding to the position of the first through hole 301, and the diameter of the first through hole 301 is larger than the diameter of the locking bolt 4, so as to avoid the locking bolt 4 interfering with the first through hole 301 and causing the right end of the movable jaw 3 to be unable to be pressed down; the locking bolt 4 passes through the first through hole 301 and is threadedly connected with the first threaded hole 102. In some specific embodiments, the first through hole 301 is a countersunk hole, and the head of the locking bolt 4 is hidden in the countersunk hole, so that there is no protrusion on the upper end surface of the movable jaw 3, which is conducive to the processing of the workpiece.

[0048] During the process of tightening the locking bolt 4, the force exerted on the movable clamp 3 by tightening the locking bolt 4 is vertically downward, and the workpiece is clamped by the horizontal displacement generated by the rotation of the right end of the movable clamp 3, that is, the force direction of the driving component of the clamp is perpendicular to the clamping direction. Compared with traditional clamps, such as vises, the force direction of the driving component is parallel to the clamping direction. The clamping method of the present application can provide a greater clamping force and a certain downward pressure, so that the workpiece can be clamped more stably.

[0049] In some specific embodiments, the jaws of the fixed jaw 2 and the movable jaw 3 are constructed with a biting structure. During the clamping process, the biting structure enables the fixed jaw 2 and the movable jaw 3 to bite into materials of conventional hardness, such as 45# steel, aluminum, copper alloy, etc., that is, the biting structure is partially embedded in the workpiece during the clamping process, thereby increasing the friction between the workpiece and the fixture, and further ensuring the stability of the fixture clamping.

[0050] In this embodiment, the angle between the bottom surface of the movable jaw 3 and the bottom surface of the clamping groove 101 is 1 degree to 45 degrees. Specifically, the angle between the bottom surface of the movable jaw 3 and the bottom surface of the clamping groove 101 is 1 degree to 5 degrees, such as 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees or any angle between 1 degree and 5 degrees. When the locking bolt 4 is tightened, the right end of the movable jaw 3 is pressed down a certain distance, and its bottom contacts the bottom surface of the clamping groove 101, thereby achieving the maximum clamping force. At this time, the right end of the movable jaw 3 cannot continue to be pressed downward, effectively avoiding the problem of damage to the workpiece caused by excessive clamping force of the movable jaw 3 and the fixed jaw 2.

[0051] In this embodiment, a support block 5 is provided on the clamping station. The support block 5 is fixedly connected to the clamping seat 1 by bolts and serves as the bottom support plate of the workpiece during clamping. The support block 5 is designed to be detachable and replaceable according to the processing material or the wear condition.

[0052] A second threaded hole 501 is provided at one end of the support block 5; the L-shaped positioning block 6 is constructed with a second through hole 601 that penetrates the L-shaped positioning block 6. After the connecting bolt 602 passes through the second through hole 601, it is screwed with the second threaded hole 501. When batch parts are processed, the vertical section of the positioning block 6 extends upward to form a protrusion at the end of the support block 5. When placing the workpiece, the end of the workpiece can be directly against the positioning block 6 to form a limit, which effectively ensures that the workpiece is placed in the same position each time, which is conducive to speeding up the efficiency of batch processing of workpieces. In the case of single-piece part processing or other situations where end positioning is not required, the connecting bolt 602 can be loosened and the positioning block 6 can be flipped downward 180°, which is convenient to use.

[0053] Embodiment 2:

[0054] Based on the first embodiment, in this embodiment, if Figure 5-Figure 10 As shown, the clamping seat 1 is connected to the workbench through the quick-change module 7 to facilitate the replacement of the clamping seat 1, or in the clamping state, the workpiece together with the clamping seat 1 is moved to another station for further processing. When in use, it is only necessary to place the quick-change module 7 at different stations in advance, and when the next step of processing is performed, the workpiece together with the clamping seat 1 is directly moved, and the clamping seat 1 can be processed after it is installed, without the need for additional tool positioning, which is conducive to improving the speed of workpiece processing.

[0055] In this embodiment, the quick-change module 7 includes a base 701 , a locking base 702 , a connecting base 703 , a locking block 704 , and a connecting block 705 .

[0056] The base 701 is fixedly connected to the workbench, and a locking base 702 is fixedly installed on the base 701. Specifically, four bolts are passed through the locking base 702 and then screwed on the base 701, thereby fixing the locking base 702 on the base 701. A first connecting hole 7021 extending vertically downward is configured on the top surface of the locking base 702, and the first connecting hole 7021 is arranged in the middle of the top surface of the locking base 702. A second connecting hole 7022 is arranged on one side surface of the locking base 702, and the second connecting hole 7022 extends horizontally toward the inside of the locking base 702 and is connected to the first connecting hole 7021. The clamping seat 1 is installed on the connecting seat 703. Specifically, two bolts are passed through the clamping seat 1 and then screwed onto the connecting seat 703, thereby fixing the clamping seat 1 on the connecting seat 703. A connecting block 705 matching the shape of the first connecting hole 7021 is provided at the bottom of the connecting seat 703. The connecting block 705 protrudes from the bottom surface of the connecting seat 703. A locking hole 7051 is provided on one side surface of the connecting block 705. The locking hole 7051 runs through the connecting block 705.

[0057] When in use, the connecting block 705 is inserted into the first connecting hole 7021 from top to bottom, and the position of the locking hole 7051 corresponds to the position of the second connecting hole 7022, and the locking block 704 passes through the second connecting hole 7022 and the locking hole 7051 from the side in sequence, thereby firmly connecting the connecting block 705 and the locking seat 702, and then firmly connecting the connecting seat 703 and the locking seat 702. The operation is convenient, which is beneficial to improving the speed of changing the workpiece position and improving the work efficiency of the staff.

[0058] In this embodiment, the left and right side walls of the locking hole 7051 are contracted inwardly to form a trumpet shape, and the left and right side surfaces of the locking block 704 are also contracted to match and are roughly conical. Therefore, in the process of inserting the locking block 704 into the locking hole 7051, the connecting block 705 is aligned with the center of the locking block 704, forming a limit on the X-axis, thereby improving the positioning accuracy of the connecting block 705, and further improving the positioning accuracy of the clamping seat 1.

[0059] The bottom surface of the locking hole 7051 is tilted upward along the insertion direction of the locking block 704, and the bottom surface of the locking block 704 is also tilted upward to match. During the process of inserting the locking block 704 into the locking hole 7051, the locking block 704 pulls the connecting block 705 downward, so that the bottom surface of the connecting seat 703 is in close contact with the top surface of the locking seat 702, thereby determining the position of the connecting seat 703 on the Z axis (height position), and at the same time ensuring the stability of the connection between the connecting seat 703 and the locking seat 702.

[0060] In this embodiment, the locking block 704 includes a first connecting portion 7041 and a second connecting portion 7042 that are perpendicular to each other, and the shape of the first connecting portion 7041 matches the locking hole 7051; the second connecting hole 7022 is a stepped hole with a step 7023, and the bolt passes through the second connecting portion 7042 and is screwed onto the thread of the step 7023.

[0061] In this embodiment, a guide rod 103 extending vertically downward is provided on the bottom surface of the clamping seat 1, and a guide hole 7031 matching with the guide rod 103 is provided on the connecting seat 703; when the clamping seat 1 is installed on the connecting seat 703, the installation position of the clamping seat 1 is determined by the guide rod 103 to improve the installation accuracy of the clamping seat 1.

[0062] In this embodiment, a cross-net-shaped anti-sticking groove 104 is constructed on the bottom surface of the clamping seat 1. The depth of the anti-sticking groove 104 is 1 mm. It mainly plays two roles. First, it increases the friction between the clamping seat 1 and the connecting seat 703; second, it prevents the formation of oil film molecules on the fitting surfaces of the clamping seat 1 and the connecting seat 703 to form a vacuum state when the clamping seat 1 and the connecting seat 703 are disassembled after using coolant, which makes it difficult to disassemble.

[0063] In this embodiment, a limiting protrusion 7052 is provided on the top surface of the connecting block 705, and a limiting groove 7032 matching the shape of the limiting protrusion 7052 is provided on the bottom surface of the connecting seat 703. When installing the connecting block 705, the position of the connecting block 705 on the bottom of the connecting seat 703 is determined by inserting the limiting protrusion 7052 into the limiting groove 7032, which is beneficial to improving the positioning accuracy of the connecting block 705, and further improving the matching accuracy of the connecting seat 703 and the locking seat 702.

[0064] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
