Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] A preferred embodiment of the clamping device for fine carving of handicrafts provided by this utility model is, for example... Figures 1 to 5 As shown: A clamping device for fine carving of handicrafts includes an operating table 1; a rotating plate 2 rotatably disposed inside the operating table 1; mounting holes 3 integrally disposed at the four corners inside the rotating plate 2; a pivot pin 4 disposed inside the mounting holes 3 and pivot pin 4 rotatably connected to the rotating plate 2; a shaped plate 5 fixedly sleeved outside the pivot pin 4; a guide hole 6 integrally disposed at the lower end inside the shaped plate 5; and a first drive assembly 7 assembled at the lower end inside the operating table 1, the first drive assembly 7 controlling the shaped plate 5 to rotate.

[0029] The first drive assembly 7 includes a support plate 701 fixedly installed inside the lower end of the operating table 1; a circular plate 702 rotatably installed on the top of the support plate 701; an electric push rod 703 fixedly installed on the top of the circular plate 702; and a pull rod 704 fixedly installed on the outer wall of the output end of the electric push rod 703. There are four pull rods 704. The pull rods 704 have an irregular cross-section when viewed from above. The pull rods 704 are installed inside the guide hole 6, and the guide hole 6 is a through hole.

[0030] It should be noted that existing clamping devices for fine carving of handicrafts still have certain shortcomings in actual use. They cannot control the clamping force of the handicrafts within the range required by the operator, which affects the clamping effect of the handicrafts.

[0031] In this embodiment, the operator first places the craft item at the middle of the top of the rotating plate 2, and then turns on the pulling function of the electric push rod 703. The electric push rod 703 drives the pull rod 704 to move downward along the direction of the guide hole 6. At this time, the pull rod 704 drives the irregular plate 5 to rotate in conjunction with the pivot pin 4. In the above manner, the upper end of the irregular plate 5 moves along the direction of the craft item.

[0032] In a further preferred embodiment of this utility model, a monitoring component 8 is assembled inside the irregular plate 5. The monitoring component 8 can monitor the clamping force on the craft. The monitoring component 8 includes a sliding plate 801 slidably disposed inside the irregular plate 5; a top pin 802 fixedly disposed on the outside of the sliding plate 801; a pressure sensor 803 fixedly disposed inside the irregular plate 5; a spring 9 is fixedly disposed on the outer wall of the sliding plate 801, and the end of the spring 9 away from the sliding plate 801 is fixedly connected to the irregular plate 5. A limit pin 15 is threaded through the outer wall of the irregular plate 5. A controller 10 is fixedly disposed on the outer wall of the operating table 1. The controller 10 is connected to the electric push rod 703 and the pressure sensor 803 through wires.

[0033] In this embodiment, when the upper end of the irregular plate 5 moves along the direction of the craft, the irregular plate 5 drives the sliding plate 801 to exert a clamping force on the outside of the craft. Through the reaction force of the craft, the sliding plate 801 causes the top pin 802 to move along the direction of the pressure sensor 803, and the spring 9 deforms. At this time, the top pin 802 exerts a squeezing force on the pressure sensor 803. When the squeezing force reaches the value set by the pressure sensor 803, the electric push rod 703 stops running. The operator then rotates the limiting pin 15, so that the limiting pin 15 exerts a squeezing force on the sliding plate 801, thereby restricting the movement of the sliding plate 801. In the above way, the clamping force on the craft is controlled within the range required by the operator.

[0034] Example 2

[0035] Based on Embodiment 1, a preferred embodiment of the clamping device for fine carving of handicrafts provided by this utility model is as follows: Figures 1 to 5 As shown: Connecting rods 11 are fixed at the four corners of the bottom of the rotating plate 2. The connecting rods 11 have an irregular shape. The end of the connecting rod 11 away from the rotating plate 2 is fixedly connected to the circular plate 702. A rack 12 is fixedly installed on the top of the circular plate 702. The rack 12 has a circular cross-section when viewed from above. The center of the rack 12 is concentric with the center of the circular plate 702. A second drive assembly is provided on the top of the support plate 701. The second drive assembly controls the circular plate 702 and the rotating plate 2 to rotate. The second drive assembly includes a motor 13 fixed on the left side of the top of the support plate 701; a gear 14 fixedly sleeved on the outside of the output end of the motor 13, and the gear 14 meshes with the teeth of the rack 12. The motor 13 is a geared servo motor with a self-locking function. The motor 13 is connected to the controller 10 through a wire.

[0036] In this embodiment, the operator turns on the motor 13, which drives the gear 14 to rotate the rack 12, the circular plate 702, the electric push rod 703, the connecting rod 11, the rotating plate 2, and the craftwork until the area to be carved on the craftwork faces the operator. Then the operator turns off the motor 13 and can then carve the craftwork.

[0037] In summary, this application, through the use of the first drive component, enables four irregularly shaped plates, along with a sliding plate, to clamp the craftwork. The monitoring function allows for control of the clamping force, and the mechanical linkage design allows the area of ​​the craftwork to be carved to face the operator, thus improving the operator's convenience in carving the craftwork.
