[0022] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0023] Please refer to Figure 1—4, A fully enclosed inner hole guiding boss device, including a box body 1. A through hole 2 is provided on the outer wall of one side of the box body 1. It also includes a torsion block 3, a torsion seat 4, a driving unit 5, a movable block 6 and a fixed seat 7. The fixed seat 7 is fixedly installed inside the through hole 2. A supporting block 8 is arranged inside the fixed seat 7. The torsion block 3 is rotatably connected to the fixed seat 7. An arc-shaped groove 31 is provided on the outer wall of the torsion block 3. A sliding groove 71 is provided on the outer wall of one side of the fixed seat 7. One end of the movable block 6 is slidably connected to the arc-shaped groove 31, and the other end of the movable block 6 is slidably connected to the sliding groove 71. The driving unit 5 is fixedly installed inside the box body 1. The torsion seat 4 is fixedly connected to the torsion block 3, and the output end of the driving unit 5 is rotatably connected to the torsion seat 4.

[0024] Specifically, the interior of the box body 1 is a hollow structure. A through hole 2 is fixedly opened on the outer wall of one side of the box body 1. The fixing seat 7 is fixedly installed inside the through hole 2 by bolts. A supporting block 8 is movably arranged inside the fixing seat 7. Preferably, the shape of the end of the supporting block 8 is adapted to the inner wall shape of the workpiece to be processed, so that the workpiece can be nested on the supporting block 8. A boss 75 is fixedly arranged on the outer wall of one side of the fixing seat 7. The torsion block 3 is integrally in a ring structure. The torsion block 3 is rotatably connected to the fixing seat 7 through the boss 75. An arc-shaped groove 31 is opened on the outer wall of one side of the torsion block 3. Preferably, as an embodiment provided by the present invention, the number of the arc-shaped grooves 31 is three, and the three arc-shaped grooves 31 are circumferentially and arrayedly distributed on the outer wall of the torsion block 3. A sliding groove 71 is opened on the outer wall of the boss 75, and the number and distribution of the sliding grooves 71 are adapted to the number and distribution of the arc-shaped grooves 31. An extrusion block 61 is fixedly installed on the outer wall of one side of one end of the movable block 6, and a sliding rod 62 is fixedly installed on the outer wall of the other end. The sliding rod 62 is adapted to the arc-shaped groove 31, so that one end of the sliding rod 62 can be slidably connected to the arc-shaped groove 31. The end of the movable block 6 away from the sliding rod 62 is slidably connected to the sliding groove 71 on the boss 75. The driving unit 5 is fixedly installed on the inner wall of one side of the box body 1. Specifically, the driving unit 5 is a telescopic cylinder. The output end of the driving unit 5 is rotatably connected to the torsion seat 4. The torsion seat 4 is fixedly connected to the torsion block 3. Therefore, the torsion seat 4 can rotate on the fixing seat 7. The driving unit 5 can be used to drive the torsion seat 4 to rotate, and the torsion block 3 can be driven to rotate through the rotation of the torsion seat 4. When the torsion block 3 rotates, the sliding rod 62 slides in the arc-shaped groove 31, and the sliding rod 62 is pushed to move through the arc-shaped groove 31, thereby driving the movable block 6 to move in the sliding groove 71. Multiple movable blocks 6 can move towards or away from each other. When multiple movable blocks 6 move towards each other, the extrusion blocks 61 arranged on the movable blocks 6 can be abutted against the workpiece, and the workpiece can be processed into a shape. When multiple movable blocks 6 move away from each other, the processing is completed. At this time, the workpiece can be taken out, optimizing the traditional extrusion process, forming three bosses at one time with one clamping, with high efficiency, and there is no situation of cumulative error caused by continuous processing of a single boss.

[0025] In this utility model, the driving unit 5 is used to drive the torsion seat 4 to rotate, and then drive the torsion block 3 connected to the torsion seat 4 to rotate. Since one end of the movable block 6 is slidably connected in the arc-shaped groove 31 and the other end is slidably connected in the sliding groove 71, when the torsion block 3 rotates, the movable block 6 can be driven to reciprocate along the sliding groove 71. When the movable block 6 moves towards the center of the torsion block 3, it can be abutted against the workpiece on the supporting block 8, and the outer wall of the workpiece is extruded inward, so that a convex block is formed inside the workpiece, which is convenient for the processing of cylindrical workpieces. By changing and increasing the number of the sliding grooves 71, the arc-shaped grooves 31 and the movable blocks 6, multiple convex blocks can be processed at one time, which can improve the processing efficiency, ensure the accuracy of subsequent assembly, and facilitate the assembly by assembly workers.

[0026] Furthermore, as Figure 4 shown, it further includes a mounting base 12. The mounting base 12 can be fixedly connected to the fixed base 7 through bolts. A circular groove 72 is provided at the axis center of the fixed base 7, and the circular groove 72 penetrates through the boss 75. A guiding block 73 is arranged inside the circular groove 72. Preferably, the setting position of the guiding block 73 is adapted to the setting position of the extrusion block 61 on the movable block 6. A receiving groove 81 is provided on the outer wall of the circumferential direction of the supporting block 8. As an embodiment provided by the present utility model, the number and distribution of the receiving grooves 81 are adapted to the number and distribution of the guiding blocks 73. The supporting block 8 is slidably connected to the guiding block 73 through the receiving groove 81. The setting of the receiving groove 81 can accommodate the convex block inside the workpiece when the movable block 6 extrudes the workpiece, preventing the convex block from damaging the supporting block 8 during the production process. At the same time, the receiving groove 81 is connected to the guiding block 73, which can provide sliding guidance for the supporting block 8 and prevent the supporting block 8 from rotating in the circular groove 72. The lifting unit 9 is fixedly installed on the outer wall of one side of the mounting base 12, and the output end of the lifting unit 9 is connected to the supporting block 8. Furthermore, as Figure 3 and Figure 1 shown, a cover plate 10 is fixedly installed on the outer wall of one side of the fixed base 7. The cover plate 10 is fixedly installed on the boss 75 of the fixed base 7. A material feeding hole 11 is provided at the axis center of the outer wall of one side of the cover plate 10. The diameter of the material feeding hole 11 is adapted to the diameter of the workpiece, so that when the workpiece is placed on the supporting block 8, the circumferential wall of the workpiece is located inside the material feeding hole 11 and the boss 75. The cover plate 10 can block the movable block 6, so that during the extrusion process, the movable block 6, the workpiece, and the receiving groove 81 on the supporting block 8 are all in a closed state, and the operator cannot put his fingers into the extrusion and stamping areas, with high safety and no potential safety hazards under normal circumstances, which can improve the safety of production. The lifting unit 9 can specifically be a lifting cylinder.

[0027] As a further embodiment provided by the present utility model, waist-shaped grooves 74 are provided on the outer wall of the fixed base 7. The number of the waist-shaped grooves 74 is three, and the three waist-shaped grooves 74 are arranged in a circumferential array. A connecting rod 41 is fixedly installed on the outer wall of the torsion seat 4. The number and distribution of the connecting rods 41 are adapted to the waist-shaped grooves 74, and one end of the connecting rod 41 penetrates through the waist-shaped groove 74 and is connected to the torsion block 3, so as to ensure that the torsion block 3 rotates synchronously while the torsion seat 4 rotates.

[0028] Working principle:

[0029] The operator first places the workpiece to be processed onto the supporting block 8 through the material feeding hole 11;

[0030] Subsequently, the switch is started, and the driving unit 5 drives the torsion seat 4 to rotate, and synchronously drives the three movable blocks 6 on the torsion block 3 to move along the sliding groove 71;

[0031] The squeezing block 61 is driven to squeeze the outer wall of the workpiece by the opposite movement of the three movable blocks 6;

[0032] After the squeezing is completed, the driving unit 5 resets, and the three movable blocks 6 reset. Subsequently, the lifting unit 9 drives the supporting block 8 to descend. After the supporting block 8 descends, the supporting block 8 is separated from the workpiece. It can abut against the workpiece through the edge at the top of the circular groove 72. At this time, there is a certain gap between the workpiece and the supporting block 8, which is convenient for the operator to take out the workpiece. After taking out the workpiece, the lifting unit 9 drives the supporting block 8 to reset.

[0033] Those skilled in the art can understand that other similar connection methods can also implement the present utility model. For example, welding, bonding or screwing, etc.

[0034] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
