[0023] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0024] like Figure 1-Figure 4 As shown, the utility model provides a universal fixture, including a base 10 and at least two locking assemblies 20.

[0025] A plurality of connecting columns 11 are fixedly mounted on the bottom of the base 10, and the connecting columns 11 are used to connect the base 10 and the workbench together. A plurality of T-shaped slots 12 extending inwardly in the transverse direction are formed on the side of the base 10.

[0026] The locking assembly 20 includes a T-block 21, a fixed block 22, a threaded column 23, a locking block 24 and a locking nut 25. The T-block 21 is arranged in the T-slot 12 and is in sliding contact with the inner wall of the T-slot 12. The limit block is arranged above the T-block 21. The threaded column 23 passes through the limit block in the longitudinal direction and is threadedly connected to the limit block, and the threaded column 23 is fixedly connected to the T-block 21. The locking block 24 is arranged above the limit block, and a waist-shaped groove 26 is provided on the locking block 24 that passes through in the longitudinal direction, and the waist-shaped groove 26 is adapted to the threaded column 23. The locking nut 25 is arranged above the locking block 24 and is threadedly connected to the threaded column 23.

[0027] In the present application, since the T-block 21 is in sliding contact with the inner wall of the T-slot 12 , the position of the entire locking assembly 20 can be moved along the direction of the T-slot 12 .

[0028] For ease of understanding and description, the number of locking assemblies 20 is limited to two to describe the use process of the present invention.

[0029] The specific use process of the utility model is as follows: first, the staff places the irregular workpiece 40 on the base 10. Then, the staff inserts the T-blocks 21 of the two locking assemblies 20 into the T-slots 12 on both sides of the irregular workpiece 40, and moves the T-blocks 21 to the appropriate position. At this time, the staff rotates the limit block until the limit block is in close contact with the base 10, and the position of the T-block 21 is fixed. Finally, due to the design of the waist-shaped groove 26, the staff moves the locking block 24 horizontally until the locking block 24 contacts the side of the irregular workpiece 40. At this time, the staff can tighten the locking nut 25 downward, so that the position of the locking block 24 is fixed. At this time, the two locking assemblies 20 can squeeze the two sides of the irregular workpiece 40 respectively, thereby forming a stable clamp for the irregular workpiece 40, and then the irregular workpiece 40 can be processed by processing equipment.

[0030] Since the position of the locking assembly 20 and the position of the locking block 24 are both movable and adjustable, the utility model can stably clamp various irregular workpieces 40 .

[0031] When the number of the locking assemblies 20 is greater than two, it should be ensured that at least two locking assemblies 20 form a stable clamping for the two sides of the irregular workpiece 40 .

[0032] In one embodiment, a plurality of threaded holes 13 extending downward are formed on the top of the base 10 .

[0033] At least one clamping assembly 30 is arranged on the base 10, and the clamping assembly 30 includes a fixed seat 31, a screw 32, a lifting plate 33, a guide rod 34, a pressure block 35, a threaded rod 36 and a clamping nut 37. The fixed seat 31 is arranged on the base 10, and a guide hole extending downward is opened on the top of the fixed seat 31. The screw 32 is arranged on the fixed seat 31, and the threaded end of the screw 32 passes through the fixed seat 31 and matches with the threaded hole 13. The lifting plate 33 is arranged above the fixed seat 31 in the horizontal direction, and a jack running through the lifting plate 33 in the longitudinal direction is opened. The first end of the guide rod 34 is fixedly connected to the lifting plate 33, and the second end of the guide rod 34 is in sliding contact with the inner wall of the guide hole. The pressure block 35 is fixedly installed at the bottom of the lifting plate 33. The threaded rod 36 passes through the jack, and the lower end of the threaded rod 36 is threadedly matched with the threaded hole 13, and the clamping nut 37 is arranged above the lifting plate 33 and threadedly matched with the threaded rod 36.

[0034] After at least two locking assemblies 20 form a stable clamp on both sides of the irregular workpiece 40, the staff will place the fixing seat 31 at a suitable position on the top, and then match the threaded end of the screw 32 with the threaded hole 13, and then the fixing seat 31 will be fixed on the base 10. Then, the staff will rotate the lifting plate 33 so that the pressing block 35 will contact the top of the irregular workpiece 40. Next, the staff will pass the threaded rod 36 through the jack and thread the lower end of the threaded rod 36 with the threaded hole 13. Finally, the staff will tighten the clamping nut 37 downward until the pressing block 35 presses the top of the irregular workpiece 40.

[0035] In this way, the clamping assembly 30 can clamp the irregular workpiece 40 in the longitudinal direction, further preventing the irregular workpiece 40 from moving, thereby improving the stability of the present invention.

[0036] In one embodiment, the pressing assembly 30 further includes a spring 38 , which is sleeved on the threaded rod 36 , a first end of the spring 38 is in contact with the lifting plate 33 , and a second end of the spring 38 is in contact with the base 10 .

[0037] When the clamping nut 37 is tightened downward, the spring 38 is in a compressed state. At this time, it can exert an upward force on the lifting plate 33, thereby preventing the lifting plate 33 and the threaded rod 36 from loosening, further improving the stability of the utility model.

[0038] In one embodiment, a pad 14 is further included, and the pad 14 is disposed on the base 10. The irregular workpiece 40 can be placed on the pad 14, which can avoid direct contact between the irregular workpiece 40 and the base 10. Since the base 10 is generally made of steel, the design of the pad 14 can reduce the wear of the irregular workpiece 40 during subsequent processing; on the other hand, the friction coefficient between the pad 14 and the irregular workpiece 40 is greater, which can further improve the stability of the utility model.

[0039] In one embodiment, chamfers are formed at the edges of the locking block 24 to better adapt to and protect the irregular workpiece 40 .

[0040] In one embodiment, there are three locking assemblies 20 , which can squeeze the irregular workpiece 40 at three points in different directions, thereby forming a stable clamp.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.

[0042] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
