[0023] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0024] Reference Figures 1 to 3 As shown, an internal support clamp is provided, including a main body 1, in which a movable connecting sleeve 2 is installed, one end of the connecting sleeve 2 is fixedly connected to an internal support chuck 4, and the internal support chuck 4 is movably arranged on an end of the main body 1 away from the connecting sleeve 2. A convex column 11 is arranged on the end of the main body 1 away from the connecting sleeve 2, and the internal support chuck 4 is sleeved on the outside of the convex column 11 and can move back and forth along the length direction of the convex column 11 so that the internal support chuck 4 can clamp or release the workpiece.

[0025] In this embodiment, the inner support chuck 4 includes a connecting seat 41 and a plurality of elastic clamping blocks 42, the plurality of clamping blocks 42 are evenly distributed on the connecting seat 41 around the axis, and the plurality of clamping blocks 42 surround a clamping opening 421. The workpiece is placed at the clamping opening 421, and one end of the connecting sleeve 2 is connected to the oil cylinder. When the connecting sleeve 2 moves toward the main body 1, the workpiece placed at the clamping opening 421 will be clamped inward by the plurality of clamping blocks 42 due to the elasticity of the clamping blocks 42. If the workpiece needs to be taken out, It is necessary to move the connecting sleeve 2 outward, and the clamping block 42 fits against the boss 11, so that the closer the clamping block 42 is to the boss 11, the more it opens outward. At this time, the aperture of the clamping port 421 becomes larger. When the aperture is larger than the outer diameter of the workpiece, the workpiece can be removed from the clamping port 421. At the same time, during the movement of the clamping block 42, the position of the boss 11 is fixed, so the boss 11 will also press against the workpiece, which is helpful for removing the workpiece. A gap is provided between two adjacent clamping blocks 42, which is helpful for each clamping block 42 to expand or retract.

[0026] Furthermore, a through hole 12 is provided at one end of the main body 1 close to the inner support chuck 4, and a connecting block 21 is provided on the connecting sleeve 2. The connecting block 21 passes through the through hole 12 and is fixedly connected to the connecting seat 41. The connecting seat 41 is provided with bolt holes. The connecting seat 41 and the connecting block 21 are fixedly connected by bolts. When the connecting sleeve 21 is driven, the connecting seat 41 also moves therewith, thereby driving a number of clamping blocks 42 to move, thereby realizing the opening or closing of the clamping mouth, thereby loosening or clamping the workpiece.

[0027] In one embodiment of the utility model, the end of the main body 1 away from the connecting sleeve 2 is fixedly connected to the positioning cover 3, and the positioning cover 3 is provided with a positioning hole 31, and the boss 11 can pass through the positioning hole 31. The positioning cover 3 is used to protect the interior of the main body 1 from damage and help position the workpiece. The positioning cover 3 is provided with a plurality of fixing holes. If the workpiece is provided with holes, it can be fixedly connected with the fixing holes to prevent the boss 11 from accidentally pushing the workpiece out of the clamping port 421 when holding the workpiece, thereby damaging the workpiece. The fixing holes can also be connected to other accessories to assist in the processing of the workpiece. The positioning hole 31 prevents the clamp block 42 from extending too much outward, causing the clamp block 42 to be overly retracted inward, causing the workpiece to be over-clamped, thereby damaging the workpiece.

[0028] Preferably, a first thread is provided on the outer side of the main body 1, and a second thread is provided on the inner side of the positioning cover 3. The main body 1 is threadedly connected to the positioning cover 3. The positioning cover 3 is twisted to tighten the positioning cover 3 on the main body 1, and vice versa, the positioning cover 3 is loosened to facilitate the disassembly and installation of the positioning cover 3.

[0029] Furthermore, a positioning protrusion 32 is provided on the positioning cover 3, and the positioning protrusion 32 is used for positioning the workpiece.

[0030] In one embodiment of the utility model, a movable cavity is provided inside the main body 1, and the connecting sleeve 2 is movably arranged in the movable cavity. There is a gap between the outer side of the connecting sleeve 2 and the movable cavity, so as to facilitate the movement of the connecting sleeve 2 in the movable cavity.

[0031] In one embodiment of the utility model, the protruding column 11 includes a first end and a second end, the first end is arranged on a side close to the connecting sleeve 2, and the second end is arranged on a side away from the connecting sleeve 2, and the outer diameter of the first end is greater than the outer diameter of the second end, so that when the clamping block 42 moves toward the main body 1, the clamping block 42 gradually expands outward, and the aperture of the clamping opening 421 becomes larger, and at this time, the workpiece is in a state of loosening; when the clamping block 42 moves in a direction away from the main body 1, the clamping block 42 gradually contracts inward, and the aperture of the clamping opening 421 becomes smaller, and at this time, the workpiece is in a state of clamping.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
