Technical Field
[0001] This utility model belongs to the field of electrical discharge cutting machine equipment, and specifically relates to a UV tapered head mechanism. Background Technology
[0002] Electrical discharge wire cutting (EDM) is a machining method that uses voltage applied between a workpiece and an electrode to induce a discharge phenomenon between the electrode and the workpiece. The high temperature and chemical reaction generated by the discharge are used to cut the workpiece. The electrode wire needs to be fed with extreme precision and stability. Existing wire guide wheel assemblies adjust parameters such as the tension of the electrode wire through the wire guide wheel and follower wheel, but the adjustment range is small. When the parameters of the electrode wire deviate significantly, traditional wire guide wheel assemblies cannot meet the adjustment requirements. Summary of the Invention

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a UV tapered head mechanism, comprising a first mounting plate, a guide wheel assembly disposed on the left side wall of the first mounting plate, a second mounting plate mounted on the upper surface of the first mounting plate, a guide head assembly, a linear motor assembly suspended on the lower surface of the second mounting plate and used to drive the guide head assembly to move on a horizontal plane, an electrode wire passing through the guide wheel assembly and then winding onto the guide head assembly, the guide wheel assembly comprising a plurality of guide wheels, follower wheels spaced apart from the guide wheels, and an adjusting guide assembly disposed between the follower wheel closest to the guide head assembly and the guide head assembly, the adjusting guide assembly comprising an adjusting base mounted on the left side wall of the first mounting plate, at least two guide posts disposed on the adjusting base, at least one of the guide posts being an adjusting guide post, the upper end of which is frustoconical in shape, and its thickness increasing or decreasing from top to bottom.
[0005] In another embodiment, any cross-section of the upper end of the adjusting guide post is elliptical. The outer circumferential surface of the adjusting guide post changes gradually not only axially but also radially, making the adjusting guide post suitable for electrode wires requiring different clamping forces and clamping directions.
[0006] In another embodiment, the adjusting base has an adjusting plane, and the adjusting plane has first adjusting holes corresponding to the guide posts. The lower ends of the guide posts are cylindrical and pass through the first adjusting holes. Rotating the adjusting guide posts can adjust the clamping rollers and clamping direction between the adjusting guide posts and the electrode wires.
[0007] In another embodiment, the adjusting base is further provided with a second adjusting hole perpendicular to and communicating with the first adjusting hole. The second adjusting hole is provided with a pin for controlling the insertion depth of the guide post into the first adjusting hole, and the end of the pin located in the second adjusting hole can penetrate deep into the first adjusting hole. By controlling the insertion depth of the adjusting guide post into the first adjusting hole with the pin, the clamping roller and clamping direction of the adjusting guide post and the electrode wire can be further adjusted.
[0008] In another embodiment, the wire guide wheel assembly includes a first wire guide wheel, a first follower wheel, a second wire guide wheel, and a second follower wheel sequentially disposed on the left side wall of the mounting plate, and the adjusting guide assembly is located between the second follower wheel and the wire guide head assembly.
[0009] In another embodiment, the guide wheel assembly includes an output block located between the adjusting guide assembly and the guide head assembly, and has a guide groove thereon, the width of which decreases from the first guide wheel to the second guide wheel.
[0010] In another embodiment, the linear motor assembly includes a first slider fixed to the lower end face of the second mounting plate, a first direction linear motor slidable in the front-back direction and disposed on the first slider, a second linear motor whose driving direction is perpendicular to the driving direction of the first direction linear motor and fixed to the first direction linear motor, a second slider slidably connected to the second linear motor, the first slider being driven by the first direction linear motor, the second slider being driven by the second direction linear motor, and a guide wire assembly fixed to the lower end face of the second slider.
[0011] In another embodiment, the mounting plate has multiple weight-reducing holes. This facilitates the installation of the UV taper head mechanism and lowers the center of gravity of the cutting machine head, thereby improving the stability of the cutting machine operation.
[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: the clamping force and clamping direction of the guide post and the electrode wire can be adjusted by the inclined side wall of the guide post, thereby adjusting the tension and torque of the electrode wire, making it run more smoothly and improving the cutting accuracy of the cutting machine.

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0017] like Figure 1-3 As shown, the UV tapered head mechanism includes a first mounting plate 1, a guide wheel assembly disposed on the left side wall of the first mounting plate 1, a second mounting plate 2 mounted on the upper end surface of the first mounting plate 1, a guide head assembly 7, a linear motor assembly suspended on the lower end surface of the second mounting plate 2 and used to drive the guide head assembly 7 to move on the horizontal plane, and the electrode wire 0 passes through the guide wheel assembly and then winds onto the guide head assembly 7. The first mounting plate 1 is vertically arranged.
[0018] Specifically, the guide wheel assembly includes several guide wheels, follower wheels spaced apart from the guide wheels, and an adjusting guide assembly located between the follower wheel closest to the guide head assembly 7 and the guide head assembly 7. The adjusting guide assembly includes an adjusting base 8 mounted on the left side wall of the first mounting plate 1 and at least two guide posts 10 disposed on the adjusting base 8. At least one of the guide posts 10 is an adjusting guide post 9, the upper end of which is frustoconical, and its thickness increases or decreases from top to bottom. Any cross-section of the upper end of the adjusting guide post 9 is elliptical. An adjusting plane is formed on the adjusting base 8, and a first adjusting hole 11 is formed on the adjusting plane corresponding to each guide post 10. The lower ends of the guide posts 10 are all cylindrical and pass through the first adjusting holes 11. The adjustment base 8 is also provided with a second adjustment hole 12 that is perpendicular to and connected to the first adjustment hole 11. The second adjustment hole 12 is provided with a pin 13 for controlling the depth of the guide post 10 inserted into the first adjustment hole 11. The end of the pin 13 located in the second adjustment hole 12 can penetrate into the first adjustment hole 11.
[0019] The wire guide wheel assembly includes a first wire guide wheel 3, a first follower wheel 5, a second wire guide wheel 4, and a second follower wheel 6, which are sequentially disposed on the left side wall of the mounting plate. The adjusting guide assembly is located between the second follower wheel 6 and the wire guide head assembly 7. The wire guide wheel assembly includes an outlet block 14, which is located between the adjusting guide assembly and the wire guide head assembly 7. The outlet block 14 is provided with a guide groove 15, the width of which decreases from the first wire guide wheel 3 to the second wire guide wheel 4.
[0020] The linear motor assembly includes a first slider 16 fixed to the lower end face of the second mounting plate 2, a first direction linear motor 17 slidably mounted on the first slider 16 in the front-back direction, a second linear motor whose driving direction is perpendicular to the driving direction of the first direction linear motor 17 and fixed on the first direction linear motor 17, and a second slider 19 slidably connected to the second linear motor.

[0021] The mounting plate has multiple weight-reducing holes 20. This facilitates the installation of the UV taper head mechanism and lowers the center of gravity of the cutting machine head, which helps improve the stability of the cutting machine operation.
[0022] The principle of this invention is as follows: The outer circumferential surface of the adjusting guide post 9 changes gradually not only axially but also radially, enabling the adjusting guide post 9 to be suitable for electrode wires 0 requiring different clamping forces and clamping directions. Rotating the adjusting guide post 9 adjusts the clamping wheel and clamping direction of the adjusting guide post 9 and electrode wire 0. The depth of insertion of the adjusting guide post 9 into the first adjusting hole is controlled by the pin 13, further adjusting the clamping wheel and clamping direction of the adjusting guide post 9 and electrode wire 0. This, in turn, adjusts the tension and torque of the electrode wire 0, making its operation more stable and improving the cutting accuracy of the cutting machine; during cutting, the linear motor assembly drives the electrode wire to move slightly along with the cutting head and as needed.
