DETAILED DESCRIPTION

[0023] See also Figures 1 to 2 , which is a schematic diagram of a multifunctional workpiece parallel clamp provided by the present invention. The multifunctional workpiece parallel clamp comprises a base 10; a slide 20 mounted on the base 10; and a wedge-shaped female block 30 and a wedge-shaped male block 40 mounted on the slide 20 and cooperating with each other. It is contemplated that the multifunctional workpiece parallel clamp may also include other functional components and specific structures, such as electrical connection components, control components, and mounting structures. These are well known to those skilled in the art and will not be described in detail here.

[0024] The base 10 serves as a mounting carrier for the multifunctional workpiece parallel clamp and is usually arranged on a moving device or a material transfer robot.

[0025] In this embodiment, a mounting hole is provided through the base 10, into which one end of the slide 20 is inserted, and then secured using bolts or other fastening structures. This installation method results in a compact mounting structure for the slide 20 and the base 10, while maintaining good compressive stability when the slide 20 is subjected to force. Sliding grooves 21 are provided on both sides of the slide 20, symmetrically arranged along the width of the base 10. The sliding grooves 21 are used to slide the wedge-shaped female block 30. The slide 20 also has a sliding channel 22 extending along the length of the base 10 and communicating with the sliding groove 21.

[0026] In other embodiments, the two sliding slots 21 may also be an integral through-groove structure.

[0027] The wedge-shaped female block 30 has two slide slots 21 on either side, one for each of the two. The wedge-shaped female block 30 engages the inner walls of the slide slots 21, constraining the wedge-shaped female block 30 within the slide slots 21. The wedge-shaped female block 30 is provided with wedge-shaped holes 31. In this embodiment, the path of the wedge-shaped holes 31 slopes outward from the end closest to the wedge-shaped male block 40. The two wedge-shaped holes 31 are symmetrically arranged, ensuring that they maintain communication with the corresponding slide channels 22.

[0028] A chuck block 32 is provided on the wedge-shaped mother block 30. In this embodiment, the chuck block 32 is used to directly contact the workpiece. A supporting surface 33 that can be pressed against the workpiece is provided on the chuck block 32. The supporting surface 33 corresponds to the clamping point of the workpiece and can move back and forth along the surface of the workpiece.

[0029] A chuck groove 34 is provided on the wedge-shaped mother block 30, and the chuck block 32 can be detachably installed in the chuck groove 34. It can be imagined that it is not limited to the plug-in installation method used in this embodiment, and other fastening methods such as bolts can also be used, which are all easy for technical personnel in this field to think of based on the existing technology.

[0030] In this embodiment, the cross-section of the wedge-shaped male block 40 is U-shaped. A driver 50 is connected to the middle of the wedge-shaped male block 40. The driver 50 is a driving cylinder. The driver 50 drives the wedge-shaped male block 40 to slide in the sliding channel 22. The slide 20 is located between the sliding channel 22 and the wedge-shaped hole 31 and is provided with a guide hole 23. Two guide parts 42 are spaced apart at one end of the wedge-shaped male block 40. The main part of the guide part 42 is fitted with the guide hole 23 to ensure the driving and guiding performance of the wedge-shaped male block 40.

[0031] A wedge portion 41 is provided at the end of the guide portion 42 away from the wedge male block 40. The wedge portion 41 is in contact with the wedge hole 31 and is longer than the wedge hole 31. It is conceivable that, in order for the wedge portion 41 to stably reciprocate in the wedge hole 31, a counterbore is provided at the end of the guide hole 23 near the wedge hole 31. Similarly, a movable cavity 24 for the wedge portion 41 to move is provided at the end of the slide 20 away from the sliding channel 22. This prevents the wedge portion 41 from interfering with the slide 20 during movement. The inner diameters of the counterbore and movable cavity 24 also serve as the range of movement for the wedge portion 41. As the driver 50 drives the wedge male block 40 to move, the wedge portion 41 and the wedge hole 31 are displaced relative to each other, causing the wedge female block 30 to move along the sliding groove 21, ultimately defining the upper and lower limits of movement of the wedge female block 30.

[0032] A spring 60 is installed between the wedge-shaped male block 40 and the slide 20. Specifically, a blind hole is defined at the end of the slide 20 closest to the wedge-shaped male block 40. The ends of the spring 60 are connected to the blind hole and the inner wall of the U-shaped wedge-shaped male block 40, respectively. The spring 60 provides a return stroke, or elastic clamping action. The specific operating principle is described below.

[0033] See also Figures 3 and 4 During the internal clamping process, the driver 50 drives the wedge-shaped male block 40 to move outward along the sliding channel 22, and the wedge-shaped portion 41 abuts against the wedge-shaped hole 31, forcing the two wedge-shaped female blocks 30 to retract inward accordingly until the two chuck blocks 32 are clamped at both ends of the workpiece. After the end, the power of the driver 50 is removed, and the spring 60 forces the wedge-shaped male block 40 to return to its original position.

[0034] During the external support process, the driver 50 drives the wedge male block 40 to move inward along the sliding channel 22 so that the wedge portion 41 abuts against the wedge hole 31, forcing the two wedge female blocks 30 to move outward accordingly until the two chuck blocks 32 are clamped on both sides of the recessed cavity of the workpiece.

[0035] In this other embodiment, during the external support process, the driver 50 drives the wedge male block 40 to move outward along the sliding channel 22, and the wedge portion 41 abuts against the wedge hole 31, forcing the two wedge female blocks 30 to retract inward accordingly, placing the workpiece on the outside of the chuck head. Then, the power of the driver 50 is removed, and the spring 60 forces the wedge male block 40 to move inward until the two chuck blocks 32 are clamped on both sides of the recessed cavity of the workpiece.

[0036] The multifunctional workpiece parallel clamp has a compact overall structure and occupies little space. It also reduces the use of elastic components, improves clamping accuracy, and increases service life. It can also adopt a variety of workpiece clamping methods such as internal clamping and external support, thereby improving the versatility of the parallel clamp.

[0037] The utility model also provides a processing jig having the multifunctional workpiece parallel clamp as described above. Except for the multifunctional workpiece parallel clamp, other components are all existing technologies or commercially available parts.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
