For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] like Figure 1 , Figure 2 As shown, a self-made clamp that is easy to adjust greatly includes a slide rail 1, a fixed block 5 fixed to a section of the slide rail 1, and a tightening block slidably arranged on the slide rail 1; a driving screw 2 is arranged at one end of the tightening block away from the fixed block 5;

[0043] One end of the driving screw rod 2 is rotatably connected to the tightening block, and the other end is threadedly connected to the threaded seat.

[0044] The threaded seat includes a fixed seat 9 and a movable seat 8. The bottom of the fixed seat 9 is fixedly connected to the slide rail 1, and the upper end of the fixed seat 9 is provided with a first semicircular threaded hole; the movable seat 8 is lifted and lowered at the upper end of the fixed seat 9 by a lifting assembly, and the lower end of the movable seat 8 is provided with a second semicircular threaded hole corresponding to the first semicircular threaded hole; the driving screw 2 is threadedly connected to the threaded hole composed of the first semicircular threaded hole and the second semicircular threaded hole.

[0045] In this embodiment, through the threaded seat of the present application, when it is necessary to significantly adjust the position of the top tightening block, it is only necessary to lift the movable seat 8, at which time the driving screw 2 is freed from the restriction of the threaded connection with the threaded seat, and the driving screw 2 can be pulled left and right, and the position of the top tightening block can be quickly adjusted by pulling the driving screw 2, and when it is moved to the desired position, the movable block can be lowered, so that the first semicircular threaded hole of the movable seat 8 and the second semicircular threaded hole of the fixed seat 9 form a complete threaded hole, so that the driving screw 2 is threadedly connected with the threaded seat, and the workpiece can be clamped by rotating the driving screw 2. In other words, through the design of the threaded seat of the present application, the movement of the top tightening block does not require the rotation of the driving screw 2 throughout the entire process, and when it is necessary to significantly move the top tightening block, it is only necessary to lift the movable seat 8, and then the staff can pull the driving screw 2 by hand to significantly adjust the position of the top tightening block, and at this time, it is not necessary to rotate the driving screw 2, which greatly increases the movement efficiency of the top tightening block.

[0046] In one embodiment, if Figure 1 , Figure 2 As shown, the lifting assembly includes a lifting screw 10 and a U-shaped plate 12 with an opening facing downward, and the bottom of the U-shaped plate 12 is fixedly connected to the slide rail 1, which can be fixed by bolts or welding. Preferably, threaded connection is adopted.

[0048] Through the structural design of this embodiment, the movable seat 8 can be lifted and lowered by rotating the lifting screw 10, which has a simple structure and is easy to operate.

[0049] It should be noted that the lifting screw 10 is connected to the top plate of the U-shaped plate 12 in radial rotation, and the axial direction needs to be limited, that is, the lifting screw 10 can only rotate, and cannot move up and down. A clamping ring can be added to the lifting screw 10 to limit the axial direction of the lifting screw 10 and prevent it from moving up and down.

[0050] In one embodiment, a handle 11 is provided on the top of the lifting screw 10, and a hand wheel 7 is provided at one end of the driving screw 2 away from the tightening block, so as to facilitate the rotation of the lifting screw 10 and the driving screw 2.

[0051] In one embodiment, a flexible connector is provided in the middle of the driving screw 2, and the flexible connector is a universal shaft 6. The driving screw 2 is connected to the top block through the universal shaft 6, which makes the driving screw "flexible" and can lift the driving screw. There are two purposes for setting the universal shaft 6. One is to realize the rotation of the driving screw 2 normally (that is, to make the driving screw 2 rotate normally), and the other is to realize the "flexible" structural design of the driving screw 2. After the movable seat 8 is raised, the driving screw 2 can be lifted from the first semicircular threaded hole of the fixed seat 9, the thread restriction is released, and it is convenient to pull the top block left and right.

[0052] In one embodiment, the fixing block 5 is an L-shaped metal block; the fixing block 5 is connected to the slide rail 1 through threads.

[0053] In one embodiment, if Figure 1 , Figure 3 As shown, the clamping block includes a first channel steel 3 and a second channel steel 4; the opening of the first channel steel 3 faces upward, and a fixed position is formed between the first side plate of the first channel steel 3 and the fixed block 5 for fixing the workpiece; the second side plate of the first channel steel 3 at one end away from the fixed block 5 is rotatably connected to one end of the driving screw 2; the number of the second channel steels 4 is two, and the two second channel steels 4 are respectively fixed to the two sides of the bottom of the first channel steel 3, and the second channel steel 4 is slidably connected to the slide rail 1. The second side plate of the first channel steel 3 has a through hole corresponding to the driving screw 2, and the end of the first channel steel 3 passes through the through hole, and the driving screw 2 is clamped in the through hole by a clamping member (for example, a clamping ring), thereby realizing axial fixation between the driving screw 2 and the second side plate, so that the driving screw 2 can rotate in the through hole and will not move axially in the through hole.

[0054] In one embodiment, T-slots 101 are provided on both sides of the slide rail 1;

[0055] The opening of the second channel steel 4 faces outward, and a roller 401 is provided on the side of the back plate of the second channel steel 4 adjacent to the slide rail 1 ; the roller 401 is connected to the back plate of the second channel steel 4 via a connecting shaft; the roller 401 is arranged in the T-slot 101 .

[0056] Based on this embodiment, the smoothness of the tightening block during movement is increased, and the friction between the tightening block and the slide rail 1 is reduced, so that the tightening block moves more smoothly, the operation is simpler and more efficient, and the movement efficiency of the tightening block is increased.

[0057] Working principle:

[0058] 1. When there is a need to fix the workpiece, turn the handle on the lifting rod to raise the movable seat.

[0059] 2. After the movable seat is raised, hold the hand wheel and lift the drive screw upward to separate the drive screw from the fixed seat, and pull the tightening block outward to increase the distance between the tightening block and the fixed block.

[0060] 3. Place the workpiece between the clamping block and the fixed block, then push the drive screw inward to reduce the distance between the clamping block and the fixed block to preliminarily clamp the workpiece.

[0061] 4. Place the drive screw in the first semicircular threaded hole of the fixed seat, lower the movable seat, and make the drive screw return to the threaded connection with the movable seat and the fixed seat.

[0062] 5. Turn the handwheel to drive the driving screw to rotate, further reducing the distance between the clamping block and the fixed block to complete the clamping and fixing of the workpiece.
