Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a positioning tool for stainless steel casing processing which is easy to adjust. Background Art

[0002] The clamping tools on the market often use a threaded handle for rotational clamping to complete the fixed clamping of the workpiece. However, the twist handle needs to be twisted during rotation and disassembly. If the internal threads are misaligned or rusted, the twist handle cannot be twisted, making adjustment inconvenient.

[0003] To solve the above problem, there is a solution of a steel pipe clamping tool (announcement number CN218800711U) that is easy to adjust. The cylinder is started to make the upper pressure hand press the steel pipe downward. As the pressing progresses, the upper pressure hand enters the through groove of the lower pressure hand, thereby completing the clamping and avoiding the longitudinal displacement of the steel pipe. When adjustment is needed, the cylinder is started to pull the spring to make the steel pipe disengage and complete the adjustment.

[0004] However, the above scheme clamps the steel pipe through the cylinder and the spring, but some thin steel pipes can only withstand limited pressure. When the cylinder is used to clamp the steel pipe, the pressure of the cylinder will cause the steel pipe to be partially flattened, causing the steel pipe to no longer be round, affecting the use of the steel pipe.

[0007] The outer clamping plate and the inner clamping plate cooperate to clamp the stainless steel casing according to the thickness of the stainless steel casing, so as to achieve the clamping and fixing of the stainless steel casing;

[0008] A stud, the stud is fixedly connected at the center of the assembly disk, an outer screw sleeve and an inner screw sleeve are screwed on the surface of the stud, the outer screw sleeve and the inner screw sleeve are both rotatably connected to a movable seat, the two movable seats are respectively rotatably connected to four outer push-pull arms and inner push-pull arms, and the outer push-pull arms and the inner push-pull arms are rotatably connected to the corresponding outer control arms and inner control arms;

[0009] The distance between the outer clamping plate and the inner clamping plate can be controlled by twisting the outer screw sleeve and the inner screw sleeve, and stainless steel casings of different thicknesses can be fixed.

[0010] Furthermore, the surfaces of the outer screw sleeve and the inner screw sleeve are both fixedly connected with an adjusting handle, and it is more convenient and labor-saving to control the outer screw sleeve and the inner screw sleeve using the adjusting handle.

[0021] A stud 3, wherein the stud 3 is fixedly connected to the center of the assembly disk 1, an outer screw sleeve 4 and an inner screw sleeve 10 are screwed on the surface of the stud 3, and a movable seat 18 is rotatably connected to the surface of the outer screw sleeve 4 and the inner screw sleeve 10, and two movable seats 18 are rotatably connected to four outer push-pull arms 6 and inner push-pull arms 11, respectively, and the outer push-pull arms 6 and the inner push-pull arms 11 are rotatably connected to the corresponding outer control arms 7 and inner control arms 12;

[0022] When the moving seat 18 translates, the two moving seats 18 can control the corresponding outer push-pull arm 6 and inner push-pull arm 11 to move. The outer push-pull arm 6 drives the outer clamping plate 8 to move through the outer control arm 7, and the inner push-pull arm 11 drives the inner clamping plate 14 to move through the inner control arm 12.

[0029] Specifically, when in use, the stainless steel sleeve 19 is sleeved on the surface of the inner clamping plate 14, and the inner screw sleeve 10 is rotated to move it to the left along the stud 3, and the inner screw sleeve 10 drives the corresponding moving seat 18 to move to the left, and the moving seat 18 drives the inner push-pull arm 11 and the inner control arm 12 to move, and the inner control arm 12 drives the four inner clamping plates 14 to fit to the inner wall of the stainless steel sleeve 19; the outer screw sleeve 4 is rotated to move it to the right along the stud 3, and the outer screw sleeve 4 drives the corresponding moving seat 18 to move to the right, and the moving seat 18 drives the outer push-pull arm 6 and the outer control arm 7 to move, and the outer control arm 7 drives the four outer clamping plates 8 to fit to the surface of the stainless steel sleeve 19. At this time, the stainless steel sleeve 19 is clamped by the inner clamping plate 14 and the outer clamping plate 8, reducing the clamping force on the stainless steel sleeve 19. For the thinner stainless steel sleeve 19, it can be stably clamped without causing deformation of the stainless steel sleeve 19.
