Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a positioning device for wire drawing on the surface of metal parts. Background Technology

[0002] Wire drawing is a metal processing technique. In metal pressure processing, metal is forced through a die under external force, compressing its cross-sectional area and obtaining the desired shape and size. The tool used to change its shape and size is called a wire drawing die.

[0003] A search of existing Chinese patent technology reveals a device called "A Metal Part Surface Wire Drawing Machine" (publication number CN215430857U). This device's rotation drives a moving rod to move left and right, which in turn moves a moving plate connected by a connecting rod. This allows the metal part to be fixed on the moving plate, and the back-and-forth movement improves the quality of the metal wire drawing. Simultaneously, when the moving plate reaches the left and right limit plates, the metal part can be replaced. The moving plate facilitates feeding the wire drawing machine, eliminating the need for manual feeding and improving processing safety. However, during wire drawing, the part is clamped near the edge of the sheet metal, affecting the processing effect. Utility Model Content

[0004] Based on this, it is necessary to address the problem that the device is clamped near the edge of the sheet metal during wire drawing, affecting the processing effect. A positioning device for wire drawing of metal parts is provided, comprising: a bottom working frame, a mounting frame fixedly connected to one side of the bottom working frame, two rectangular holes opened at the upper end of the bottom working frame, the surface of the mounting frame extending above the rectangular holes, a telescopic frame installed inside the mounting frame, and a grinding belt sleeved on the surface of the telescopic frame; a positioning mechanism installed above the bottom working frame, the surface of the positioning mechanism penetrating the rectangular holes and extending below the bottom working frame; wherein, the positioning mechanism includes a guide component installed inside the rectangular holes, the surface of the guide component extending below the bottom working frame, a servo motor connected to one end of the guide component, the servo motor installed at one end of the bottom working frame, and a clamping component installed at the upper end of the guide component.

[0005] In one embodiment, the guide assembly includes a guide rail fixedly connected to the inner wall of a rectangular hole, a guide slide seat slidably connected to the inner wall of the guide rail, a connecting frame fixedly connected between two guide slide seats, a positioning circular hole provided inside the connecting frame, and a guide threaded sleeve fixedly connected to the inner wall of the positioning circular hole.

[0006] In one embodiment, the clamping assembly includes a plurality of support brackets slidably connected to the upper end of the guide slide seat. The upper end of the guide slide seat has a plurality of threaded holes, which are evenly distributed in a straight line along the surface of the guide slide seat. The support brackets have a top hole inside.

[0007] In one embodiment, the inner wall of the guide threaded sleeve is threaded with a guide threaded rod, which is fixedly connected to the output shaft of the servo motor.

[0008] In one embodiment, the guide thread rod is located between two rectangular holes and is rotatably connected to the surface of the bottom work frame.

[0009] In one embodiment, the inner wall of the top hole is provided with two positioning bolts, the lower ends of which extend to the lower end of the support frame.

[0010] In one embodiment, the lower end of the positioning bolt extends into the interior of the adjacent threaded hole, and the surface of the positioning bolt is threaded to the inner wall of the threaded hole.

[0011] In one embodiment, the upper end of the support is engaged with a clamping bolt, and the lower end of the clamping bolt passes through a top hole and is threaded with a fastening nut. Beneficial effects

[0012] The aforementioned positioning device for wire drawing of metal parts, through the cooperation of the guide component and the clamping component, the positioning bolt and the threaded hole can be connected to securely position the support frame, and the support frame supports the bottom of the wire drawing plate, so that the clamping bolt and the upper end of the support frame clamp the plate. The clamping bolt is tightened by the set fastening nut, so that the edge of the plate can be wire drawn normally, ensuring the processing effect of the plate.

[0013] By setting a guide component, the guide thread rod and the guide thread sleeve cooperate under the action of the guide component, so that the connecting frame moves linearly along the axis of the guide thread rod. Then, the connecting frame drives the two guide sliding seats to move synchronously, so that the connecting frame drives the two guide sliding seats to move synchronously linearly on the inner wall of the adjacent guide rail, so that the guide component assists in accurately positioning the clamping component.

[0025] Positioning mechanism 3 is installed above the bottom work frame 1. The surface of positioning mechanism 3 passes through the rectangular hole 11 and extends to the bottom of the bottom work frame 1. Positioning mechanism 3 includes a guide component 31 installed inside the rectangular hole 11. The surface of guide component 31 extends to the bottom of the bottom work frame 1. One end of guide component 31 is connected to a servo motor 33. The servo motor 33 is installed at one end of the bottom work frame 1. A clamping component 32 is installed at the upper end of guide component 31.

[0026] like Figure 1-4 As shown, the guide assembly 31 includes a guide rail 311 fixedly connected to the inner wall of the rectangular hole 11. A guide sliding seat 316 is slidably connected to the inner wall of the guide rail 311. A connecting frame 312 is fixedly connected between the two guide sliding seats 316. A positioning circular hole 313 is opened inside the connecting frame 312. A guide threaded sleeve 314 is fixedly connected to the inner wall of the positioning circular hole 313. A guide threaded rod 315 is threadedly connected to the inner wall of the guide threaded sleeve 314. The guide threaded rod 315 is fixedly connected to the output shaft of the servo motor 33. The guide threaded rod 315 is located between the two rectangular holes 11. The guide threaded rod 315 is rotatably connected to the surface of the bottom work frame 1.

[0027] In this embodiment, the guide thread rod 315 is driven to rotate synchronously by the drive servo motor 33. The guide thread rod 315 and the guide thread sleeve 314 are engaged to make the connecting frame 312 move linearly along the axis of the guide thread rod 315. Then, the connecting frame 312 drives the two guide sliding seats 316 to move synchronously, so that the connecting frame 312 drives the two guide sliding seats 316 to move synchronously linearly on the inner wall of the adjacent guide rail 311.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, the clamping assembly 32 includes multiple support brackets 324 slidably connected to the upper end of the guide slide seat 316. The upper end of the guide slide seat 316 is provided with multiple threaded holes 321, which are evenly distributed in a straight line along the surface of the guide slide seat 316.

The clamping bolt 322 is tightened by the fastening nut 326, so that the part of the plate near the edge can get a good processing effect.

[0031] Working principle: The drive servo motor 33 drives the guide thread rod 315 to rotate synchronously. The guide thread rod 315 cooperates with the guide thread sleeve 314. The connecting frame 312 moves linearly along the axis of the guide thread rod 315. The connecting frame 312 drives the two guide sliding seats 316 to move synchronously. The connecting frame 312 drives the two guide sliding seats 316 to move linearly on the inner wall of the adjacent guide rail 311. The positioning bolt 323 is connected to the threaded hole 321 to fix the support frame 324 in place. The support frame 324 supports the bottom of the wire drawing plate. The clamping bolt 322 clamps the plate at the upper end of the support frame 324. The clamping bolt 322 is tightened by the fastening nut 326.
