A position-adjustable aluminum alloy stir friction welding fixture disclosed includes a lifting platform mechanism, and a fixed fixture mechanism is slidably connected to the lifting platform mechanism. The fixed fixture mechanism includes a slider, a connecting column, a movable column, a connecting rod, a threaded hole, a threaded rod, a knob, and a rotating block. And a clamping block, the slider is located inside the slide groove of the lifting platform mechanism, the connecting column is located at the top of the slider, the movable column is located at the top of the connecting column, the connecting column penetrates into the movable column and is connected with a round block, the connecting rod is located on the outer wall of the movable column near the top, the threaded hole is located at the top of the connecting rod and penetrates to the bottom of the connecting rod, the threaded rod and the inner wall of the threaded hole are mutually sleeved, the knob is located at the top of the threaded rod, the rotating block is located at the bottom of the threaded rod, and the clamping block and the outer wall of the rotating block are mutually sleeved; the movable column can rotate the knob on the connecting column to drive the threaded rod to rotate and adjust the position of the clamping block.

[0003] The tooling clamp rotates the clamp block to above the material by rotating the movable column, so that the clamp block swings relative to the connecting column. However, after the clamp block is rotated into place, it can only form a locking operation from the top of the clamp block downward, so the position of the clamp block cannot be locked well, and the position of the clamp block is fixed by the friction between the clamp block and the material. In this way, the clamp block is easy to rotate relative to the material, causing dislocation between the clamp block and the material, and the clamping position of the clamp block cannot be adjusted. When the clamping area is too small, it cannot be adjusted by movement to ensure the reliability of clamping. Summary of the invention

[0004] The utility model provides a clamp with adjustable position for sheet metal parts. After a clamp block is rotated into position, a locking piece is used to lock the clamp block to limit the rotation position of the clamp block on a connecting column. The clamp block will not swing relative to the workpiece, and the clamp block has a good clamping effect on the workpiece.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a sheet metal position adjustable clamp, including a connecting column, a supporting assembly and a clamping block are sleeved on the connecting column, the clamping block is arranged above the supporting assembly and abuts against the supporting assembly, a through hole is provided in the clamping block, the connecting column is penetrated in the through hole and the clamping block is rotatably arranged in the through hole, the through hole is arranged along the length direction of the clamping block, the clamping block is movably arranged in the through hole, a locking piece is provided above the clamping block, the locking piece is provided with a first threaded hole, an external thread is provided on the outer wall surface of the connecting column, and the first threaded hole is threadedly connected to the connecting column to press the clamping block onto the supporting assembly.

[0006] The above arrangement is that the clamp is installed on the frame for use, and the workpiece to be clamped is placed between the clamp block and the frame, and the clamp block is supported by the supporting assembly, and the through-hole of the clamp block cooperates with the connecting column to realize the movement of the clamp block in the circumferential direction of the connecting column, so that the position of the clamp block can be adjusted by rotating the clamp block, and the clamp block can clamp different positions of the workpiece. When the clamp block is rotated into place; the clamp block is locked by a locking piece. Since the locking piece is locked at the upper end of the clamp block, and the lower end of the clamp block is supported by the supporting assembly, and the locking piece and the supporting assembly are both arranged on the connecting column, the clamp block can be acted on from the upper and lower surfaces of the clamp block to limit the rotation position of the clamp block on the connecting column, and the clamp block will not swing relative to the workpiece, and the clamp block has a good clamping effect on the workpiece. At the same time, the clamp block can move along the length direction so that the contact area of ​​the workpiece can be adjusted according to actual needs, thereby achieving a good clamping effect.

[0007] Furthermore, one end of the clamping block is used to contact the workpiece, and the other end of the clamping block is connected to a support portion, which is located below the clamping block and extends along the length direction of the connecting column.

[0008] In the above arrangement, the bottom of the support portion is used to abut against the frame body, and under the action of the support portion, the supporting effect on the clamping block is improved.

[0009] Furthermore, a protrusion is provided on the bottom surface of the support portion, and the cross-sectional area of ​​the protrusion is smaller than the cross-sectional area of ​​the bottom surface of the support portion.

[0011] Furthermore, the support portion and the clamping block are detachably connected.

[0012] The above arrangement facilitates the disassembly and assembly of the support part on the clamping block.

[0013] Furthermore, the connecting column is a threaded column, the supporting component is provided with a second threaded hole, and the supporting component is threadedly connected to the connecting column through the second threaded hole.

[0014] The above arrangement is connected to the connecting column through the threaded connection of the supporting component. When the supporting component is installed in place on the connecting column, the movement of the supporting component is restricted along the height direction of the connecting column, which provides good stability for the support of the clamping block.

[0015] Furthermore, a cushion block is provided between the locking piece and the clamping block, and the cushion block is sleeved on the connecting column; the cross-sectional area of ​​the cushion block is greater than the cross-sectional area of ​​the locking piece.

[0016] The above arrangement increases the contact area between the locking member and the clamping block by providing the spacer block, and the locking member has a good locking effect on the clamping block. BRIEF DESCRIPTION OF THE DRAWINGS

A locking piece 4 is provided above the clamping block 3, and the locking piece 4 is provided with a first threaded hole. The connecting column 1 is a threaded column, and the first threaded hole is threadedly connected to the connecting column 1 to press the clamping block 3 onto the supporting component 2.

[0024] The workpiece 7 to be clamped is placed between the clamp block 3 and the frame 6, and the clamp block 3 is supported by the supporting assembly 2.

Since the locking member is locked at the upper end of the clamp block, and the lower end of the clamp block is supported by the supporting assembly, and the locking member and the supporting assembly are both arranged on the connecting column, the clamp block can be acted on from the upper and lower surfaces of the clamp block to limit the rotation position of the clamp block 3 on the connecting column 1, the clamp block 3 will not swing relative to the workpiece 7, and the clamp block 3 has a good clamping effect on the workpiece 7.

[0025] The support assembly 2 is provided with a second threaded hole, and the support assembly 2 is threadedly connected to the connecting column 1 through the second threaded hole. Through the threaded connection between the support assembly 2 and the connecting column 1, when the support assembly 2 is installed in place on the connecting column 1, the movement of the support assembly 2 is limited along the height direction of the connecting column 1, and the support of the clamping block 3 is stable. The support assembly 2 includes more than one support member 21. In this embodiment, three support members 21 are provided, and the three support members 21 are stacked along the height direction of the connecting column 1. The support member 21 and the locking member 4 are nuts.

[0026] The through hole 31 is a waist hole, and the through hole 31 is arranged along the length direction of the clamp block 3. The through hole 31 is arranged as a waist hole, so that the clamp block 3 can be moved relative to the connecting column 1 along the length direction of the clamp block 3, thereby increasing the contact area between the clamp block 3 and the workpiece 7; the reliability is good.

[0027] In this embodiment, one end of the clamp block 3 is used to contact the workpiece 7, and the other end of the clamp block 3 is connected to the support portion 5, which is located below the clamp block 3 and extends along the length direction of the connecting column 1. The bottom of the support portion 5 is used to abut against the frame 6, and under the action of the support portion 5, the support effect on the clamp block 3 is improved. A protrusion 51 is convexly provided on the bottom surface of the support portion 5, and the cross-sectional area of ​​the protrusion 51 is smaller than the cross-sectional area of ​​the bottom surface of the support portion 5. The protrusion 51 is provided to contact the frame 6 to reduce the contact area between the support portion 5 and the frame 6, thereby reducing the friction between the support portion 5 and the frame when the clamp block 3 is rotated.

[0028] The support portion 5 is detachably connected to the clamp block 3, which facilitates the disassembly and assembly of the support portion 5 on the clamp block 3. In this embodiment, a first mounting hole 32 is provided on the other end of the clamp block 3, and a second mounting hole 52 is provided in the support portion 5. The second mounting hole 52 is a threaded hole. A bolt passes through the first mounting hole 32 and is threadedly connected to the second mounting hole 52, thereby realizing a detachable connection between the support portion 5 and the clamp block 3, and the structure is simple.

[0029] In this embodiment, the connecting column 1 is detachably arranged on the frame 6, and a stopper 11 is provided at the bottom of the connecting column 1; the connecting column 1 is passed through the frame 6, and the stopper 11 contacts the bottom surface of the frame 6, referring to Figure 3 As shown, the clamp is installed on the frame body 6 by the abutment portion 11 abutting against the bottom surface of the frame body 6 and the protrusion 51 of the support portion 5 abutting against the top surface of the frame body 6 .

[0030] A cushion block 8 is provided between the locking member 4 and the clamping block 3, and the cushion block 8 is sleeved on the connecting column 1; the cross-sectional area of ​​the cushion block 8 is larger than the cross-sectional area of ​​the locking member 4. By providing the cushion block 8, the contact area between the locking member 4 and the clamping block 3 is increased, and the locking effect of the locking member 4 on the clamping block 3 is good.

[0031] The working principle of the utility model is as follows: the workpiece 7 is placed between the clamp block 3 and the frame body 6, and the locking piece 4 is tightened. Under the pressure of the locking piece 4, the clamp block 3 presses the workpiece 7 onto the frame body 6 to achieve clamping of the workpiece 7. When adjusting the contact area between the clamp block 3 and the workpiece 7, the locking piece 4 is released, and the clamp block 3 is moved along the length direction of the clamp block 3. The clamp block 3 moves horizontally relative to the connecting column 1 and the workpiece 7, thereby changing the contact area between the clamp block 3 and the workpiece 7, and then the locking piece 4 is re-locked; when adjusting the contact position of the clamp block 3 and the workpiece 7, the locking piece 4 is released, and the clamp block 3 is swung along the circumferential direction of the connecting column 1. The clamp block 3 swings horizontally relative to the connecting column 1 and the workpiece 7, thereby changing the clamping position of the clamp block 3 on the workpiece 7, and then the locking piece 4 is re-locked.
