An adjusting bolt 19 is screwed on the second transverse section 16. The axis direction of the adjusting bolt 19 is parallel to the axis direction of the first circular plate 8. One end of the bolt head of the adjusting bolt 19 passes through the corresponding waist-shaped slot 10.

[0027] A second T-block 20 is fixedly arranged at one end of the first T-block 18 close to the axis of the first circular plate 8. The second T-block 20 is inclined relative to the axis of the first circular plate 8. The distance between the end of the second T-block 20 close to the top plate 2 and the axis of the first circular plate 8 is smaller than the distance between the end of the second T-block 20 away from the top plate 2 and the axis of the first circular plate 8.

[0028] An action hole 21 with two ends passing through is provided at the axis of the first circular plate 8, and an action rod 22 is slidably inserted in the action hole 21, and the axis of the action rod 22 is kept coincident with the axis of the first circular plate 8. An action block 23 is fixedly provided at one end of the action rod 22 close to the top plate 2, and the action block 23 is a cubic structure; the action block 23 is located between the four second T-shaped blocks 20, and a second T-shaped slot 24 is respectively provided on the four end surfaces of the action block 23, and the four second T-shaped blocks 20 are slidably inserted in the four second T-shaped slots 24 respectively.

[0029] A third T-slot 25 is provided at one end of the action rod 22 away from the top plate 2, and the extension direction of the third T-slot 25 is perpendicular to the axis of the action rod 22. A first adjustment cylinder 26 is rotatably provided inside the third T-slot 25, and the axis of the first adjustment cylinder 26 coincides with the axis of the first circular plate 8. A first threaded column 27 is provided outside the end of the action rod 22 away from the top plate 2, and the first threaded column 27 coincides with the axis of the action rod 22. The first threaded column 27 and the first adjustment cylinder 26 are fixedly connected by a first connecting column. A hexagonal countersunk hole 28 is provided at the center of the end surface of the first threaded column 27 away from the top plate 2.

[0030] A cylindrical fixed cylinder 29 is fixedly arranged at the center of the end face of the bottom plate 1 away from the top plate 2, and the axis of the fixed cylinder 29 coincides with the axis of the first circular plate 8. An insertion groove is arranged at the center of the end face of the fixed cylinder 29 facing the top plate 2, and the end of the action rod 22 away from the top plate 2 is inserted into the insertion groove of the fixed cylinder 29; a first threaded hole is arranged at the center of the end face of the fixed cylinder 29 away from the top plate 2, and the first threaded hole is connected to the insertion groove. The first threaded column 27 is screwed into the first threaded hole.

[0031] When the four sliding seats 5 need to be adjusted, it is only necessary to insert the hexagonal wrench into the hexagonal counterbore 28 of the first threaded column 27, and rotate the hexagonal wrench to rotate the first threaded column 27. Since the first threaded column 27 is threadedly connected with the first threaded hole of the fixed cylinder 29, the first threaded column 27 is driven to move along the axis of the fixed cylinder 29. When the first threaded column 27 rotates, it drives the first adjustment cylinder 26 to slide inside the third T-slot 25 of the actuating rod 22. At the same time, when the first threaded column 27 moves axially, it also drives the actuating rod 22 to move axially through the first adjustment cylinder 26, and the actuating rod 22 drives the actuating block 23 to move along the axial direction of the actuating rod 22.

[0032] When the action block 23 moves toward the side close to the top plate 2, under the mutual cooperation of the second T-block 20 and the second T-slot 24, the first T-block 18 is driven to move inside the first T-slot 14 in the direction away from the axis of the first circular plate 8, thereby driving the four sliding seats 5 to move in the direction away from the axis of the first circular plate 8, thereby realizing the outward expansion of the four sliding seats 5.

[0033] When the action block 23 moves toward the side away from the top plate 2, under the mutual cooperation of the second T-block 20 and the second T-slot 24, the first T-block 18 is driven to move inside the first T-slot 14 toward the direction close to the axis of the first circular plate 8, thereby driving the four sliding seats 5 to move toward the direction close to the axis of the first circular plate 8, thereby realizing the inward retraction of the four sliding seats 5.

[0034] A support seat 6 is respectively arranged outside one end of the second transverse section 16 of the four sliding seats 5 away from the axis of the first circular plate 8. The end surface of the support seat 6 away from the axis of the first circular plate 8 is an arc surface. A fourth T-slot 30 is fixedly arranged on the end surface of the support seat 6 close to the axis of the first circular plate 8. The fourth T-slot 30 is arranged obliquely relative to the axis of the first circular plate 8. The distance between the end of the fourth T-slot 30 close to the top plate 2 and the axis of the first circular plate 8 is greater than the distance between the end of the fourth T-slot 30 away from the top plate 2 and the axis of the first circular plate 8. An adjustment block 31 is arranged between the support seat 6 and the sliding seat 5. The end surface of the adjustment block 31 close to the axis of the first circular plate 8 fits the sliding seat 5. The end surface of the adjustment block 31 away from the axis of the first circular plate 8 is fixedly arranged with a third T-block 32. The third T-block 32 is slidably inserted into the fourth T-slot 30.

[0035] A fifth T-shaped slot 33 is provided on the end face of the adjusting block 31 away from the top plate 2, and a second adjusting cylinder 34 is rotatably provided inside the fifth T-shaped slot 33. The second adjusting cylinder 34 is fixedly connected to one end of the adjusting bolt 19 close to the top plate 2 through a second connecting column.

[0036] When the adjusting bolt 19 is rotated, since the adjusting bolt 19 is threadedly connected to the second transverse section 16 of the sliding seat 5, the adjusting bolt 19 is driven to move along the axis of the first circular plate 8. When the adjusting bolt 19 rotates, the second adjusting cylinder 34 is driven to rotate inside the fifth T-slot 33. At the same time, the adjusting bolt 19 also drives the adjusting block 31 to move along the axis of the first circular plate 8 through the second adjusting cylinder 34.

[0037] When the adjusting block 31 moves toward the side close to the top plate 2, the third T-block 32 and the fourth T-slot 30 cooperate with each other to drive the support seat 6 to move toward the direction close to the axis of the first circular plate 8, thereby achieving the inward retraction of the support seat 6. When the adjusting block 31 moves toward the side away from the top plate 2, the third T-block 32 and the fourth T-slot 30 cooperate with each other to drive the support seat 6 to move toward the direction away from the axis of the first circular plate 8, thereby achieving the outward expansion of the support seat 6.

[0038] The independent adjustment mechanism 7 includes an adjustment cylinder 35 , a second threaded column 37 , an adjustment nut 36 , and an adjustment seat 38 .

[0039] The adjusting cylinder 35 is a cylindrical structure with one end open. The unopened end of the adjusting cylinder 35 is fixedly arranged on the end face of the fixed block 3 away from the axis of the first circular plate 8. The axis of the adjusting cylinder 35 is arranged along the radial direction of the first circular plate 8. An adjusting nut 36 is rotatably arranged at the opening of the adjusting cylinder 35. A second threaded column 37 is screwed inside the adjusting nut 36. One end of the second threaded column 37 is inserted into the inside of the adjusting cylinder 35. An adjusting seat 38 is rotatably arranged at the other end of the second threaded column 37. The end face of the adjusting seat 38 away from the second threaded column 37 is an arc surface.

[0040] The four supporting seats 6 and the four adjusting seats 38 are arranged alternately.

[0041] The working principle of the present invention is: When processing the composite cylinder, the cylinder needs to be clamped and positioned, and a set of combined clamps provided by the present invention is placed at the openings at both ends of the cylinder. One end of the top plate 2 of the combined clamp is inserted into the opening of the cylinder, and the end surfaces of the four positioning plates 11 close to the top plate 2 are in contact with the outer side of the opening of the cylinder. At this time, the four support seats 6 and the four adjustment seats 38 are all inserted into the opening of the cylinder.

[0042] Then, the hexagon wrench is inserted into the hexagon counterbore 28 of the first threaded column 27, and the first threaded column 27 is rotated by rotating the hexagon wrench. Since the first threaded column 27 is screwed with the first threaded hole of the fixing cylinder 29, the first threaded column 27 is driven to move along the axis of the fixing cylinder 29 toward the side close to the top plate 2. When the first threaded column 27 rotates, the first adjustment cylinder 26 is driven to slide inside the third T-slot 25 of the action rod 22. At the same time, when the first threaded column 27 moves axially, it also drives the action rod 22 to move axially through the first adjustment cylinder 26, and the action rod 22 drives the action block 23 to move along the axial direction of the action rod 22 toward the side close to the top plate 2. Under the mutual cooperation of the second T-block 20 and the second T-slot 24, the first T-block 18 is driven to move inside the first T-slot 14 toward the direction away from the axis of the first circular plate 8, thereby driving the four sliding seats 5 to move toward the direction away from the axis of the first circular plate 8, thereby realizing the outward expansion of the four sliding seats 5. When the outer arc surface of the support seat 6 contacts the inner wall of the cylinder, the rotation of the hexagonal wrench is stopped, and the self-centering function of the combined clamp is realized.

[0043] Then check the contact between the four support seats 6 and the inside of the cylinder. For the support seat 6 that has not yet contacted the inside of the cylinder, rotate the adjusting bolt 19 corresponding to this support seat 6. Since the adjusting bolt 19 is screwed with the second transverse section 16 of the sliding seat 5, the adjusting bolt 19 is driven to move along the axis of the first circular plate 8 toward the side away from the top plate 2. When rotating, the adjusting bolt 19 drives the second adjusting cylinder 34 to rotate inside the fifth T-slot 33. At the same time, the adjusting bolt 19 also drives the adjusting block 31 to move along the axis of the first circular plate 8 toward the side away from the top plate 2 through the second adjusting cylinder 34; when the adjusting block 31 moves toward the side away from the top plate 2, under the mutual cooperation of the third T-block 32 and the fourth T-slot 30, the support seat 6 is driven to move in the direction away from the axis of the first circular plate 8, thereby realizing the outward expansion of the support seat 6, so that this support seat 6 also keeps in contact with the inner wall of the cylinder.

[0044] Then, the adjusting nuts 36 of the four independent adjusting mechanisms 7 are rotated so that the second threaded column 37 moves toward the outside of the adjusting cylinder 35 until the adjusting seat 38 outside the second threaded column 37 also keeps contact with the inner wall of the cylinder.

[0045] Then continue to rotate the hexagonal wrench so that the four support seats 6 continue to expand outward to achieve the tightening of the inner wall of the cylinder. At the same time, it is necessary to observe the contact between the four support seats 6 and the four adjustment seats 38 and the inner wall of the cylinder to ensure that the four support seats 6 and the four adjustment seats 38 are in reliable contact with the inner wall of the cylinder. When the hexagonal wrench is rotated to the specified torque, stop applying force. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.
