DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] like Figs. 1-3 As shown, this embodiment provides a circular carving machine, including a bed 10, a base 11 on the bed 10, a chuck 12 on one side of the base 11, a Y-axis transmission mechanism on the other side of the base 11 opposite to the chuck 12, a rotary ejector pin 14 on the Y-axis transmission mechanism, and up-and-down sliding mechanisms on both sides of the bed 10, which are controlled by a motor to move up and down. A crossbeam 16 is on the up-and-down sliding mechanism, and a swing shaft 17 on one side of the crossbeam 16 is aligned with the length direction of the crossbeam 16. A carving component 18 is mounted on the swing shaft 17.

[0023] Furthermore, the sliding mechanism in this embodiment is specifically as follows: uprights 15 are fixed on both sides of the bed 10, and through grooves 28 are provided on the opposite surfaces of the uprights 15. The two ends of the through grooves are close to the top and bottom of the uprights, respectively. A reciprocating screw 26 is provided inside the uprights 15, and a motor 25 is provided on the top of the uprights 15. The motor controls the rotation of the reciprocating screw. A moving block 27 is screwed on the reciprocating screw. The two ends of the crossbeam 16 are connected to the moving blocks on both sides, respectively. The rotation of the reciprocating screw drives the moving blocks to move up and down, thereby realizing the Z-axis function.

[0024] It should be noted that the top of the reciprocating lead screw 26 is controlled by a motor, and a limit plate 28 is added at the bottom to prevent the bottom from shaking.

[0025] The swing shaft 17 is suspended from the crossbeam 16 via the support arm 19, which serves as the fulcrum for driving the rotation of the swing shaft 17. The control unit uses a computer to transmit signals to control the direction of movement.

[0026] The chuck 12, the first rotating ejector pin 14, and the engraving assembly 18 are each provided in several groups, and they correspond one-to-one. In this embodiment, eight groups are provided.

[0027] It should be noted that the column 15 in this embodiment adopts a double-column design and an enlarged motor, thereby reducing vibration during processing and achieving processing requirements more efficiently, at higher speeds, and with higher precision. The addition of reinforcing ribs inside the square tube further enhances machine stability and extends its service life.

[0028] The Y-axis transmission mechanism is provided in two parallel sets. Each set of Y-axis transmission mechanisms is provided with a tailstock 20. A screw is screwed on the tailstock 20. One end of the screw is fixedly connected to the handwheel 21, and the other end is connected to the rotary pin 14.

[0029] The chuck 12 is driven to rotate by a motor.

[0030] The cross beam 16 is reinforced by welding reinforcing ribs at intervals. The strength of the cross beam 16 with a long span is increased.

[0031] Further scheme of the embodiment: a Y-direction moving platform mechanism is arranged between the lathe bed 10 and the base 11 to control the forward and backward movement of the base 11.

[0032] The Y-direction moving platform mechanism comprises a fixed table 22 connected with the lathe bed 10 and a moving table 23 connected with the base 11, the fixed table 22 is provided with a limiting groove 24, the moving table 23 is inserted into the limiting groove 24, and the fixed table 22 and the moving table 23 are connected and driven by a lead screw.

[0033] Since the column and the cross beam 16 are arranged above the base 11 like a gantry, and the tailstock 20 and the chuck 12 are located on the two sides respectively, the existence of the cross beam 16 will hinder the installation process, therefore, the Y-direction moving platform mechanism is adopted, the moving table 23 is moved in the limiting groove 24 by the lead screw, when the cross beam 16 is moved out from below, the installation is carried out, after the installation is completed, the moving table 23 is moved to the other side by the lead screw, so that the workpiece is located below the cross beam 16 to the specified position.

[0034] In this document, the terms "comprise", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements, but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, an element defined by the statement "comprising a" does not exclude the existence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0035] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "setting", "installing", "connecting", "connecting" should be understood broadly, for example, it can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0036] The above is only an example and description of the structure of the utility model, and those skilled in the art can make various modifications or supplements to the described specific embodiments or replace them with similar ways, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, which shall belong to the protection scope of the utility model.
