Description

Technical Field

[0001] This utility model relates to the field of grinding fixture technology, and in particular to a grinding fixture for a quick-positioning silicon steel sheet punching die. Background Technology

[0002] The quick-positioning silicon steel sheet punching die punch sharpening fixture is a clamping tool specifically designed for the precise sharpening of punches in stamping dies.

[0003] Chinese utility model patent CN212946630U discloses a fixture for processing the length of a die punch. In use, this device uses a V-shaped limiting plate to clamp the die punch with a circular outer wall. However, in practice, to consider the contact surface during clamping, rubber pads are often placed on the outer wall of the limiting plate to improve clamping stability. Simultaneously, the outer wall of the die punch may be contaminated with oil during operation. After clamping, the oil adheres to the rubber pad. During subsequent clamping and fixing, the lubricating properties of the oil reduce the friction between the rubber pad and the die punch, resulting in insufficient clamping force. This causes displacement or slippage of the die punch during processing, thus affecting processing accuracy and stability. Therefore, this paper proposes a sharpening fixture for a quick-positioning silicon steel sheet punch. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sharpening fixture for a quick-positioning silicon steel sheet punching die.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sharpening fixture for a quick-positioning silicon steel sheet punching die includes a base plate. Two sets of side plates are fixedly connected to the outer walls of both sides of the base plate. A double-threaded rod is rotatably connected between the two sets of side plates. The double-threaded rod is connected to two sets of clamping plates through a connecting mechanism. Both sets of clamping plates are slidably connected to the upper end of the base plate. A placement groove is provided on the upper end of the base plate. A rubber pad is fixedly connected to the outer wall of the clamping plate. A scraper is slidably connected to the outer wall of the rubber pad and is slidably connected in the placement groove. A sliding groove is provided on the outer wall of the clamping plate, and a driving mechanism for driving the scraper to slide is installed in the sliding groove.

[0007] Preferably, the driving mechanism includes an adjusting block slidably connected in the groove, a bracket fixedly connected to the outer wall of the adjusting block, and the end of the bracket fixedly connected to the scraper.

[0008] Preferably, a threaded rod is rotatably connected to the bottom of the groove, and the adjusting block is threadedly connected to the threaded section of the threaded rod.

[0009] Preferably, the connecting mechanism includes two sets of sliders threadedly connected to the threaded section of a double-ended threaded rod, and the two sets of sliders are respectively fixedly connected to their adjacent clamping plates.

[0010] Preferably, a limiting rod is fixedly connected between the other two sets of side plates, and two sets of limiting blocks are slidably connected to the outer wall of the limiting rod. The two sets of limiting blocks are respectively coaxially fixedly connected to their adjacent clamping plates.

[0011] Preferably, the end of the adjusting block is slidably connected to the inner wall of the slide groove, and the outer wall of the clamping plate is rotatably connected to a gear.

[0012] Preferably, the gear is coaxially and fixedly connected to the threaded rod, and a rack is fixedly connected to the upper end of the base plate, with the gear and rack meshing with each other.

[0013] Preferably, a servo motor is fixedly connected to the outer wall of one of the side plates, and the end of the output shaft of the servo motor is coaxially fixedly connected to its adjacent double-threaded rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model uses the meshing transmission of gears and racks to drive the threaded rod to rotate, causing the adjusting block on its thread to drive the scraper to slide along the surface of the rubber pad. When sliding, the oil stains attached to its outer wall can be cleaned, effectively keeping the rubber pad clean and preventing the decrease in clamping force caused by oil stains, thus further improving the reliability and durability of the clamp.

[0016] 2. This utility model uses a servo motor to drive a double-headed threaded rod, which enables the clamping plates on both sides to slide synchronously. The rubber pads installed on the clamping plates can make precise contact with the outer wall of the die punch, achieving a stable and uniform clamping. This ensures that the die punch will not shift during the grinding process, thereby improving the processing accuracy and stability. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A sharpening fixture for a quick-positioning silicon steel sheet punching die includes a base plate 1. Two sets of side plates 2 are fixedly connected to the outer walls of both sides of the base plate 1. A double-threaded rod 3 is rotatably connected between the two sets of side plates 2. The double-threaded rod 3 is connected to two sets of clamping plates 5 through a connecting mechanism. Both sets of clamping plates 5 are slidably connected to the upper end of the base plate 1. A placement groove is opened at the upper end of the base plate 1. A rubber pad 8 is fixedly connected to the outer wall of the clamping plate 5. A scraper 9 is slidably connected to the outer wall of the rubber pad 8. The scraper 9 is slidably connected in the placement groove. A sliding groove 12 is opened on the outer wall of the clamping plate 5. A driving mechanism for driving the scraper 9 to slide is installed in the sliding groove 12. By driving the scraper 9 to slide, the surface of the rubber pad 8 can be effectively cleaned, preventing oil accumulation and maintaining clamping force. It should be noted that during specific clamping, the scraper 9 is positioned below the die punch to avoid conflict with it.

[0025] The drive mechanism includes an adjusting block 14 that is slidably connected in the slide groove 12. A bracket 10 is fixedly connected to the outer wall of the adjusting block 14. The end of the bracket 10 is fixedly connected to the scraper 9. A threaded rod 13 is rotatably connected to the bottom of the slide groove 12. The adjusting block 14 is threadedly connected to the threaded section of the threaded rod 13.

[0026] The connecting mechanism includes two sets of sliders 4 threadedly connected to the threaded section of the double-ended threaded rod 3. The two sets of sliders 4 are fixedly connected to their adjacent clamping plates 5. In addition, a limit rod 6 is fixedly connected between the two sets of side plates 2. Two sets of limit blocks 7 are slidably connected to the outer wall of the limit rod 6. The two sets of limit blocks 7 are coaxially fixedly connected to their adjacent clamping plates 5. The end of the adjusting block 14 is slidably connected to the inner wall of the slide groove 12. A gear 15 is rotatably connected to the outer wall of the clamping plate 5. Through the connection between the sliders 4 on the double-ended threaded rod 3 and the clamping plates 5, the two sets of clamping plates 5 can move synchronously to realize automatic adjustment of clamping, which can adapt to different sizes of die punches and improve work efficiency.

[0027] Gear 15 is coaxially and fixedly connected to threaded rod 13. Rack 16 is fixedly connected to the upper end of base plate 1. Gear 15 and rack 16 mesh with each other. Servo motor 11 is fixedly connected to the outer wall of a set of side plates 2. The output shaft end of servo motor 11 is coaxially and fixedly connected to the adjacent double-headed threaded rod 3. Through the meshing transmission of gear 15 and rack 16, the automatic movement of adjusting block 14 and scraper 9 is realized.

[0028] In this utility model, when the device is used, firstly, the operator places the die punch to be sharpened in the placement groove at the upper end of the base plate 1, and then drives the double-headed threaded rod 3 to rotate through the servo motor 11, so that the clamping plates 5 on both sides slide close to each other on the base plate 1. The rubber pads 8 installed on the surface of the clamping plates 5 contact the outer wall of the die punch and begin to clamp, thereby achieving the clamping and fixing of the die punch. At this time, the scraper 9 is located below the die punch.

[0029] After the punch is sharpened, the double-headed threaded rod 3 is reversed by the servo motor 11, which drives the clamping plate 5 to slide to both sides. During this process, the meshing of the gear 15 and the rack 16 drives the threaded rod 13 to rotate, causing the adjusting block 14 to move in the slide groove 12, thereby pushing the bracket 10 to drive the scraper 9 to slide along the outer wall of the rubber pad 8, thereby cleaning the oil stains on the surface of the rubber pad 8 and effectively preventing the problem of insufficient clamping force caused by oil stains.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
