Description

Technical Field

[0001] The utility model belongs to the technical field of positioning tooling, and relates to a positioning tooling for wire cutting of wax pattern material. Background Art

[0002] Wire cutting is short for wire electrical discharge machining, which refers to a machining method. It is developed on the basis of electric discharge machining for punching and forming. It uses a moving metal wire as the electrode wire, and relies on the pulsed electric discharge between the electrode wire and the workpiece to generate high temperature to melt or vaporize the metal, forming a cutting seam, so as to cut out parts. The cutting speed is an important index to reflect the machining efficiency, that is, the so-called machining speed. It is the feeding speed of the electrode wire along the graphic machining trajectory multiplied by the thickness of the workpiece, that is, the area swept by the electrode wire on the workpiece per unit time.

[0003] During the existing wire cutting process, the wax pattern material is first placed on adjacent left and right support plates. On one of the support plates, there are devices such as threaded rods and pressing blocks. By placing the pressing block on one side of the wax pattern material and turning the nut at the same time, the force generated by the meshing of the nut and the threaded rod is transmitted to the pressing block to fix the wax pattern material. However, the wax pattern material on the other side is not positioned, resulting in a movable state, and further causing the wax pattern material to shake and shift during cutting, affecting the machining accuracy.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present utility model will be further described below with reference to the accompanying drawings.

[0026] As Figure 1-5As shown in the figure, a positioning tooling for wire cutting of mold materials includes an operating table 1 and a wire cutting machine 2. An inner groove 11 is provided in the operating table 1, and a bracket 3 is installed in the inner groove 11. A top plate 31 is installed at the top of the bracket 3. A sliding groove 32 is provided on the outer wall of the upper side of the top plate 31. At the same time, a right support plate 4 is installed on the top plate 31. A left support plate 41 is provided on one side of the right support plate 4. A fixing block 42 is installed on the left support plate 41. Threaded holes 43 are provided at both ends of the left support plate 41. A threaded rod 44 is inserted through the threaded holes 43. A lever 45 is installed at the top of the threaded rod 44. A round block 5 is installed in the middle of the right support plate 4. At the same time, a threaded rod 44 is installed on the round block 5. A limiting block 6 is installed at the top of this threaded rod 44. A pressing block 61 is installed directly below the limiting block 6. A slot 62 is provided in the pressing block 61. A positioning device 7 is installed on one side of the fixing block 42. In the positioning device 7, square blocks 71 are symmetrically installed. A sliding rod 72 is inserted through the square blocks 71. An electric telescopic rod 73 is installed between adjacent square blocks 71. A cross-shaped block 74 is installed at one end of the electric telescopic rod 73. Two groups of side plates 8 are symmetrically provided on one side of the cross-shaped block 74. A cylinder 81 is installed between adjacent side plates 8. Connecting plates 82 are installed at both ends of the cylinder 81. At the same time, a roller 83 is installed at one end of the side plate 8.

[0027] In this embodiment, how the wire cutting machine 2 performs wire cutting work is prior art, so it will not be described in detail.

[0028] Combined with Figure 1 、 Figure 4 As shown, the brackets 3 are symmetrically installed, the top plate 31 is installed horizontally, and both ends of the sliding groove 32 penetrate the outer wall of the top plate 31.

[0029] Furthermore, as can be seen in the figure, the contours of both ends of the sliding groove 32 are concave-shaped. The right support plate 4 and the left support plate 41 can be installed so that the threaded rod 44 and the limiting block 6 can be inserted into the sliding groove 32, and then the right support plate 4 and the left support plate 41 can move along the sliding groove 32, thereby adjusting the distance between the two to adapt to mold materials of different sizes.

[0030] Combined with Figure 1 、 Figure 5 As shown, the threaded rod 44 at the round block 5 is inserted into the slot 62. The diameter of the threaded rod 44 is smaller than the inner diameter of the slot 62. A nut is meshed and installed on this threaded rod 44, and the size of this nut is larger than the slot 62.

[0031] Furthermore, place the pressing block 61 on the mold material, and at the same time rotate the nut here to make the nut and the threaded rod 44 mesh with each other, so that the pressing block 61 closely adheres to the mold material to fix the position of the lower mold material and prevent it from falling off.

[0032] Combined with Figure 1 , Figure 5 As shown, the threaded hole 43 is located directly above the sliding groove 32. At the same time, the threaded hole 43 and the threaded rod 44 are meshed with each other, and a limit block 6 is installed at the bottom of the threaded rod 44. The limit block 6 is located in the sliding groove 32, and at this time, the limit block 6 and the sliding groove 32 are slidably connected. Threaded holes 43 and threaded rods 44 are also provided at both ends of the right support plate 4.

[0033] Furthermore, after the right support plate 4 and the left support plate 41 can move along the sliding groove 32 to a suitable position, rotate the lever 45 to drive the threaded rod 44 to rotate, and then the limit block 6 at its bottom closely adheres to the inner wall of the sliding groove 32. Therefore, the right support plate 4 and the left support plate 41 can be fixed at the required positions.

[0034] Combined with Figure 1 , Figure 5 As shown, the positioning device 7 is located on the left support plate 41. The sliding rod 72 and the square block 71 are slidably connected, and at the same time, one end of the sliding rod 72 is connected to the cross-shaped block 74.

[0035] Furthermore, the electric telescopic rod 73 is responsible for pushing the cross-shaped block 74 forward, and the sliding rods 72 on both sides play a role in supporting and guiding the cross-shaped block 74.

[0036] Combined with Figure 1 , Figure 5 As shown, two groups of connecting plates 82 are provided between the side plates 8. Both ends of the connecting plate 82 are inserted between the side plates 8. A pin shaft penetrates through the side plates 8, and the side plates 8, the connecting plate 82, and the cylinder 81 are rotatably connected through the pin shaft.

[0037] Furthermore, symmetrically arranged upper and lower side plates 8 are installed on each side. The connecting plate 82 is inserted between adjacent side plates 8, a cylinder 81 is provided between the connecting plates 82, and the cylinder 81 and the connecting plate 82 are rotatably installed between the side plates 8 through a pin shaft.

[0038] Combined with Figure 1 , Figure 3 As shown, one end of the cross-shaped block 74 is inserted between the connecting plates 82, and the cross-shaped block 74 and the connecting plate 82 are rotatably connected. The roller 83 and the side plate 8 are rotatably connected, and at the same time, the diameter of the roller 83 is greater than the width of the side plate 8.

[0039] Furthermore, when the roller 83 abuts against the outer wall of the mold material, since the outer contours of different mold materials are also different, the side plates 8 on both sides will move to different degrees, and the middle connecting plate 82 will also shift to different degrees. Therefore, it can adapt to different types of mold materials.

[0040] The working principle of the present utility model is:

[0041] Insert the threaded rods 44 and the limit blocks 6 at the right support plate 4 and the left support plate 41 into the sliding slots 32. The right support plate 4 and the left support plate 41 move along the sliding slots 32. Adjust the distance between the two according to the size of the molding compound. After the right support plate 4 and the left support plate 41 move along the sliding slots 32 to the appropriate positions, rotate the lever 45 to drive the threaded rod 44 to rotate. Then the limit block 6 presses tightly against the inner wall of the sliding slot 32, thereby fixing the right support plate 4 and the left support plate 41 in place.

[0042] Place the molding compound on the right support plate 4 and the left support plate 41, and at the same time make one side of it closely adhere to the fixed block 42. Place the pressing block 61 on the molding compound, and rotate the nut to make it engage with the threaded rod 44, thereby fixing the molding compound by using the pressing block 61.

[0043] Then the electric telescopic rod 73 pushes the cross-shaped block 74 to move, and then the roller 83 abuts against the outer wall of the molding compound. Because the outer wall contours of the molding compound are different, the two side plates 8 will shift to different degrees, and the movement states of the two side plates 8 will also be different. There may be a misalignment situation between the two side plates 8. Then the middle connecting plate 82 will also change to an inclined state accordingly, and at the same time the cross-shaped block 74 will also rotate appropriately at the connecting plate 82. Thus, the positioning device 7 can adapt to different models of molding compounds.

[0044] The specific embodiments described in this article are only examples to illustrate the spirit of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present utility model.
