Description

Technical Field

[0001] This utility model relates to the field of sculpture work tooling technology, specifically to a turntable for sculpture work. Background Technology

[0002] As a specialized device for sculpture, the turntable used in sculpture work not only requires good stability but also convenient rotation to allow the working surface to be switched at any time according to the progress of the carving. Existing turntables for sculpture work generally lack feasible and effective rotation and fixing functions. During the carving process, the turntable is prone to unavoidable slight swaying and shaking, requiring the sculptor to hold it steady or to install a dedicated positioning mechanism to fix the turntable and overcome the swaying and shaking, thus causing inconvenience in use. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a turntable for sculpting operations, which can reliably lock after the turntable rotates to a predetermined position, keeping the turntable in a stable and reliable locked state, and can easily switch between the locked state and the freely rotatable state.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a turntable for sculpting operations, including a turntable that matches the frame pivot, an armature ring, an electromagnet ring, and multiple pressing parts.

[0005] A groove is formed on the lower end face of the turntable, and an elastic pad is fixed on the inner bottom surface of the groove, so that the outer end face of the elastic pad is retracted inward relative to the port of the groove.

[0006] The armature ring and the electromagnet ring are arranged opposite each other and both are sleeved on the pivot of the turntable. The electromagnet ring is positioned directly below the armature ring and is fixed to the frame. The upper end of the armature ring can be inserted into the slot on the turntable.

[0007] Multiple pressing parts are arranged alternately around the circumference of the electromagnet ring, including screw blocks and support springs. The screw blocks are matched with the electromagnet ring through a vertically extending threaded structure, allowing the screw blocks to move vertically up and down relative to the electromagnet ring. The lower end of the support spring is fixedly connected to the upper end of the screw block, and the upper end is matched with the armature ring, thus supporting the armature ring to maintain a vertical distance relative to the electromagnet ring.

[0008] The selected support spring should have strong torsional resistance, be less prone to axial bending, and be relatively easy to undergo vertical expansion and contraction deformation.

[0009] In the initial state, the initial supporting elastic force of the supporting spring is adjusted by adjusting the height position of the screw block on the electromagnet ring part, so as to adjust the force of the armature ring part acting on the rotating table, to make the elastic pad significantly compress and deform, to increase the static friction resistance between the armature ring part and the rotating table, so that the rotating table cannot rotate freely and can be stably kept in the static state. When the direction of the rotating table needs to be adjusted, the foot switch is stepped to make the electromagnet ring part generate electromagnetic attraction, to make the armature ring part move downward, and the elastic pad arranged on the rotating table is removed, so that the rotating table can restore to the free state and can rotate under the action of external force.

[0010] Optionally, the armature ring part comprises a bearing ring I and an armature block fixed on the lower end face of the bearing ring I. The upper end of the bearing ring I can be inserted into the sink groove on the rotating table, and the protruding strip body is arranged on the upper end face of the bearing ring I.

[0011] After the protruding strip body is arranged, when the armature ring part pushes the rotating table upward, the protruding strip body can be sunk into the elastic pad, the static friction resistance between the armature ring part and the rotating table can be further increased, and the mechanical blocking action can be generated, which helps the rotating table to be more stably and reliably kept in the static state relative to the rack.

[0012] Optionally, a plurality of protruding shafts are arranged on the lower end face of the bearing ring I. The protruding shafts are matched with the supporting springs one by one and the protruding shafts are inserted into the upper ends of the supporting springs.

[0013] Optionally, a light column counterbore corresponding to the supporting spring is formed on the upper end of the screw block, and the lower end of the supporting spring is inserted into the light column counterbore.

[0014] Optionally, a plurality of resistance parts and a rib plate corresponding to the resistance parts and formed on the rack are further included.

[0015] A boss is formed on the lower part of the rotating table, and the sink groove is formed on the lower end face of the boss. A plurality of tooth grooves are arranged on the side wall of the boss in the circumferential direction, so that the side surface of the boss is formed as a tooth surface.

[0016] The resistance part comprises a protruding tooth body, a connecting rod, an assembly cylinder and a thrust spring.

[0017] One end of the connecting rod is fixedly connected with the protruding tooth body, and the other end is inserted into the cylinder cavity of the assembly cylinder.

[0018] The assembly cylinder is fixedly connected with the rib plate, so as to fix the resistance part on the rack.

[0019] The thrust spring is arranged in the barrel cavity of the assembling barrel and one end of the thrust spring is in contact with one end of the connecting rod extending into the assembling barrel, so that the thrust force can be applied on the connecting rod.

[0020] The free end of the protruding tooth body is directed to the sidewall of the boss and can be engaged with the tooth groove, so that the protruding tooth body can be switchingly engaged with each tooth groove when the rotary table rotates.

[0021] Optionally, the resistance part further comprises a pressing block, a screw rod and an end cap.

[0022] The pressing block is arranged in the barrel cavity of the assembling barrel and in contact with the end of the thrust spring. The end cap is fixedly arranged at the end of the assembling barrel and a threaded through hole is formed in the end cap. The screw rod is matched with the threaded through hole and the rod end of the screw rod extends into the assembling barrel and is fixedly connected with the pressing block.

[0023] By adjusting the matching position of the screw rod on the end cap, the length of the screw rod extending into the assembling barrel can be adjusted, that is, the axial position of the pressing block in the assembling barrel is adjusted, so that the compression degree of the thrust spring is adjusted and controlled.

[0024] The utility model discloses the beneficial effect is: the utility model discloses can realize reliable locking after rotary table rotates to predetermined position, make rotary table keep under stable, reliable locking state, and can conveniently switch between locking state and the state of free rotation.

[0031] Multiple supporting legs 101 are provided on the frame 100. A boss 11 is formed at the lower part of the rotary table 10, and an annular sink is formed at the lower end surface of the boss. An elastic pad 13 is fixedly arranged on the inner bottom surface of the sink, and the outer end surface of the elastic pad 13 is inwardly retracted relative to the port of the sink. Multiple tooth grooves 111 (fine tooth grooves) are distributed around the circumferential direction on the side wall of the boss 11, so that the side surface of the boss 11 is formed as a tooth surface / toothed surface.

[0032] The armature ring part 20 and the electromagnet ring part 30 are arranged opposite to each other and are both sleeved on the pivot 12 of the rotary table 10. The electromagnet ring part 30 is located directly below the armature ring part 20, and the electromagnet ring part 30 is fixed on the frame 100. The upper end of the armature ring part 20 can be inserted into the sink on the rotary table 10.

[0033] The armature ring part 20 includes a bearing ring I 21 and an armature block 22 fixedly arranged on the lower end surface of the bearing ring I 21. The upper end of the bearing ring I 21 can be inserted into the sink on the rotary table 10, and protruding strip bodies 212 (or protruding bodies, not limited to strip shape) are distributed on the upper end surface of the bearing ring I 21.

[0034] Multiple protruding shafts 211 are distributed on the lower end surface of the bearing ring I 21. The protruding shafts 211 correspond to the supporting springs 42 one by one and are inserted into the upper ends of the supporting springs 42 to establish a fixed connection relationship. A plug hole structure matching the upper end of the supporting spring 42 can also be formed on the bearing ring I 21 to establish a fixed connection relationship between the two.

[0035] The electromagnetic ring part 30 is provided with an electromagnetic body 32 on the bearing ring two 31, and the electromagnetic body 32 is arranged vertically opposite to the armature block 22 arranged on the bearing ring one 21, so that the electromagnetic body 32 can exert magnetic attraction on the armature block 22, and the armature ring part 20 is moved downward to approach the electromagnetic ring part 30.

[0036] A plurality of pressing parts 40 are arranged on the electromagnetic ring part 30 in the circumferential direction, including a screw block 41 and a supporting spring 42. The screw block 41 is matched with the bearing ring two 31 of the electromagnetic ring part 30 through a threaded structure arranged in the vertical direction, so that the screw block 41 can be lifted and moved in the vertical direction relative to the electromagnetic ring part 30. The lower end of the supporting spring 42 is fixedly connected to the upper end of the screw block 41, and the upper end is matched with the armature ring part 20, so that the armature ring part 20 can be supported to maintain a vertical distance relative to the electromagnetic ring part 30.

[0037] The selected supporting spring 42 should have strong torsional resistance and be not easy to bend in the axial direction, but be relatively easy to stretch and deform in the vertical direction.

[0038] In the initial state, the initial supporting force of the supporting spring 42 is adjusted by adjusting the height position of the screw block 41 on the electromagnetic ring part 30, so as to adjust the pressure of the armature ring part 20 acting on the turntable 10, so as to cause the elastic pad 13 to be significantly compressed and deformed, so as to increase the static friction resistance between the armature ring part 20 and the turntable 10, so that the turntable 10 cannot be freely rotated, and can be stably maintained in a static state. When it is necessary to adjust the direction of the turntable 10, the electromagnetic ring part 30 is powered to generate electromagnetic attraction, so that the armature ring part 20 moves downward, and the compression of the elastic pad 13 arranged on the turntable 10 is removed, so that the turntable 10 can be restored to a free state, and can rotate under the action of external force.

[0039] After the convex strip body 212 is arranged, when the armature ring part 20 pushes the turntable 10 upward, the convex strip body 212 can be caused to sink into the elastic pad 13, so as to further increase the static friction resistance between the armature ring part 20 and the turntable 10, and a mechanical blocking action can be generated, so as to help the turntable 10 to be more stably and reliably maintained in a static state relative to the rack 100.

[0040] A light column counterbore corresponding to the supporting spring 42 is formed at the upper end of the screw block 41, so that the lower end of the supporting spring 42 is inserted into the light column counterbore.

[0041] A rib plate 102 corresponding to the resistance part 50 is formed on the frame 100. The resistance part 50 comprises a protruding tooth body 51, a connecting rod 52, an assembling cylinder 53, a thrust spring 54, a pressing block 55, a screw rod 56 and an end cap 57.

[0042] One end of the connecting rod 52 is fixedly connected with the protruding tooth body 51, and the other end extends into the cylinder cavity of the assembling cylinder 53.

[0043] An arm plate 531 is formed on the side wall of the assembling cylinder 53, and the resistance part 50 is fixed on the frame 100 through the fixed connection of the arm plate 531 and the rib plate 102.

[0044] The thrust spring 54 is arranged in the cylinder cavity of the assembling cylinder 53, and one end of the thrust spring 54 is in contact with the end of the connecting rod 52 extending into the assembling cylinder 53, so that the thrust force can be applied to the connecting rod 52.

[0045] The free end of the protruding tooth body 51 faces the side wall of the boss 11 and can engage with the tooth groove 111, so that the protruding tooth body 51 can be switchedly engaged with each tooth groove 111 when the rotating table 10 rotates.

[0046] The pressing block 55 is arranged in the cylinder cavity of the assembling cylinder 53 and in contact with the end of the thrust spring 54. The end cap 57 is fixedly arranged at the end of the assembling cylinder 53, and a threaded through hole is formed in the end cap 57. The screw rod 56 matches the threaded through hole, and the rod end of the screw rod 56 extends into the assembling cylinder 53 and is fixedly connected with the pressing block 55.

[0047] By adjusting the matching position of the screw rod 56 on the end cap 57, the length of the screw rod 56 extending into the assembling cylinder 53 can be adjusted, that is, the axial position of the pressing block 55 in the assembling cylinder 53 can be adjusted, so as to realize the adjustment and control of the compression degree of the thrust spring 54.

[0048] By arranging the resistance part 50, the free rotation state of the rotating table 10 can be further limited, which helps to better maintain the rotating table 10 in a stationary state. In addition, after arranging the resistance part 50, the driving force for driving the rotating table 10 to rotate is only slightly increased, which does not adversely affect the rotation of the rotating table 10 relative to the frame 100.
