[0039] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0040] Example:

[0041] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment discloses a tooling that is beneficial for high-precision cutting, including a housing 10, a support column 20, a clamping assembly 30, a linear drive assembly 40, and a circumferential drive assembly 50. The housing 10 is elongated and has a certain weight, which is sufficient to ensure that the blank 60 will not move easily when clamped and during processing.

[0042] The interior of the housing 10 is hollow, and the top of the housing 10 has a long strip-shaped groove 11, which is arranged along the length of the housing 10.

[0043] The support column 20 is a cylindrical structure. It is slidably disposed within the slide groove 11 and can reciprocate along the length of the slide groove 11. The support column 20 is arranged vertically, while the housing 10 is arranged horizontally. A clamping assembly 30 is fixedly disposed at the top of the support column 20. The clamping assembly 30 is used to clamp the blank 60 of the required part.

[0044] A linear drive assembly 40 is disposed within the housing 10. The output end of the linear drive assembly 40 reciprocates within the housing 10 along its length, and the top of the linear drive assembly 40 has a circular groove. The bottom end of the aforementioned support column 20 is movably disposed within this groove, and the bottom end of the support column 20 can rotate within this groove.

[0045] The circumferential drive assembly 50 is disposed inside the housing 10, and the circumferential drive assembly 50 moves together with the linear drive assembly 40 inside the housing 10. In addition, the output end of the circumferential drive assembly 50 is poweredly connected to the support column 20 and is used to drive the support column 20 to rotate.

[0046] The working principle of this embodiment is as follows: First, the blank 60 of the part is mounted on the clamping assembly 30. Then, according to the pre-set program, the linear drive assembly 40 and the circumferential drive assembly 50 are controlled. During operation, the circumferential drive assembly 50 controls whether the clamping assembly 30 and the blank 60 rotate, and the rotation angle. The linear drive assembly 40 controls whether the clamping assembly 30 and the blank 60 move horizontally, and the distance they move. In addition, by coordinating with the movement of the electrode wire of the wire EDM machine, the entire part processing can be completed.

[0047] In this embodiment, the electrode wire of the wire EDM machine only needs to move horizontally along the direction perpendicular to the length of the housing 10. Therefore, the control of the electrode wire movement is greatly simplified. Furthermore, since the linear drive assembly 40 and the circumferential drive assembly have simple structures, their control methods are also very simple.

[0048] This technical solution can greatly reduce the control time for processing relatively simple parts on an online cutting machine, thereby improving processing efficiency.

[0049] In one specific embodiment:

[0050] The circumferential drive assembly 50 includes a support plate 51, a first motor 52, and a spur gear 53. The support plate 51 is slidably disposed within the housing 10, and the direction of movement of the support plate 51 is consistent with the length direction of the housing 10. The support plate 51 is poweredly connected to the output end of the linear drive assembly 40. The first motor 52 is disposed on the support plate 51 and moves together with the support plate 51.

[0051] There are two spur gears 53, which are respectively mounted on the output shaft of the first motor 52 and the support column 20, and the two spur gears 53 mesh with each other.

[0052] During operation, the first motor 52 drives the two spur gears 53 to rotate, thereby driving the support column 20 to rotate, which in turn drives the clamping assembly 30 and the blank 60 to rotate.

[0053] By setting the support plate 51, the first motor 52 and the spur gear 53 can be driven to move together with the output end of the linear drive assembly 40.

[0054] Preferably, the support plate 51 has a through hole in the middle, through which the support column 20 passes, and the support column 20 is rotatably connected to the support plate 51, typically through a bearing. In this design, since the support column 20 is poweredly connected to the output end of the linear drive assembly 40, connecting the support plate 51 and the support column 20 allows the support plate 51 to move along with the output end of the linear drive assembly 40 when the support column 20 moves with it.

[0055] Preferably, the housing 10 is provided with a slide for the support plate 51 to slide. By providing the slide, the direction of movement of the support plate 51 is restricted, so that the support plate 51 can only move in a straight line.

[0056] In addition, in order to improve the rotational accuracy of the clamping assembly 30 and the blank 60, the number of teeth of the two spur gears 53 is set to a ratio of 3:1 or greater, and the spur gear 53 with more teeth is placed on the support column 20. Thus, when the output shaft of the first motor 52 rotates multiple times, the support column 20 only rotates once, thereby achieving accurate control.

[0057] In another specific embodiment:

[0058] The linear drive assembly 40 includes a drive block 41, a screw 42, and a second motor 43. The drive block 41 has the aforementioned groove on its top and a threaded hole in its middle, which is a through hole and is positioned horizontally.

[0059] The screw 42 is matched with the threaded hole on the drive block 41. One end of the screw 42 is rotatably connected to one end inside the housing 10, and the other end of the screw 42 is coaxially connected to the output shaft of the second motor 43. Meanwhile, the second motor 43 is located on the other end of the housing 10.

[0060] By driving the screw 42 to rotate forward or backward by the second motor 43, the drive block 41 can move within the housing 10, thereby driving the circumferential drive assembly and the support column 20 to move on the housing 10.

[0061] Preferably, the housing 10 is provided with a strip groove 12 for the drive block 41 to move, and the movement direction of the drive block 41 is restricted by the strip groove 12.

[0062] In another specific embodiment:

[0063] The clamping assembly 30 includes a base plate 31, studs 32, nuts 33, and a pressure plate 34. The base plate 31 is fixedly mounted on the top of the support column 20, and the surface of the base plate 31 is located on a horizontal plane. Multiple studs 32 are vertically arranged on the base plate 31, all of which are close to one side of the base plate 31, and each stud 32 is matched with a nut 33.

[0064] The pressure plate 34 is located above the base plate 31 and has multiple holes through which all the studs 32 pass.

[0065] When installing the blank 60 on the clamping assembly 30, the side of the blank 60 is placed between the base plate 31 and the clamping plate, and the blank 60 is stably clamped by matching the nut 33 and the stud 32.

[0066] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
