Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a magnetic sheet metal quick positioning fixture. Background Technology

[0002] In sheet metal processing, fixtures play a crucial role, ensuring that sheet metal parts maintain a stable position and posture during processing, thereby guaranteeing processing accuracy and quality. Currently, in automated sheet metal processing, robotic arms are often used in conjunction with magnetic clamps to achieve rapid positioning of sheet metal parts.

[0003] However, while traditional magnetic clamps can achieve rapid positioning, in actual use, if there is an unexpected power outage, the magnetic attraction disappears, and the sheet metal parts will fall off the clamps. This will not only damage the sheet metal parts and processing equipment, but may also pose a safety threat to the operators, posing a significant safety hazard. Utility Model Content

[0004] In view of the problems existing in the current magnetic sheet metal quick positioning fixture, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a magnetic sheet metal quick positioning fixture, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A magnetic sheet metal quick positioning fixture includes a mounting plate and electromagnet chucks. Multiple electromagnet chucks are arranged in a rectangular array at the four corners of the lower surface of the mounting plate. A groove is formed on the upper surface of the mounting plate, and through holes are formed in the middle of multiple side walls of the groove. A sliding rod is slidably disposed inside the through holes. A magnetic attraction mechanism for moving the sliding rod is disposed inside the groove. A vertical plate is fixedly disposed at one outer end of the sliding rod. A first adjusting plate is disposed below the vertical plate. A first adjusting mechanism for moving the first adjusting plate longitudinally is disposed between the vertical plate and the first adjusting plate. A second adjusting plate is disposed parallel to one side of the first adjusting plate. A second adjusting mechanism for moving the second adjusting plate horizontally is disposed between the first and second adjusting plates. A support plate is fixedly disposed at the lower end of the second adjusting plate, near the mounting plate.

[0008] Preferably, the magnetic attraction mechanism includes an electromagnet plate and an iron block. The electromagnet plate is fixedly disposed on the inner wall of the groove and at a position corresponding to the through hole. The iron block is fixedly disposed at the end of the slide rod away from the first adjusting plate. A spring is movably sleeved on the wall of the slide rod, and the two ends of the spring are fixedly connected to the corresponding electromagnet plate and the iron block, respectively.

[0009] With the above setup, the iron block can be magnetically attracted by the electromagnet plate, allowing the support plate to be moved away from under the mounting plate. This facilitates the magnetic attraction of the sheet metal parts by the electromagnet chuck. By disconnecting the power supply to the electromagnet plate, the spring pushes the iron block to reset, which in turn drives the slide rod to reset, thereby causing the support plate to reset to under the sheet metal parts. This effectively protects the sheet metal parts and prevents them from falling due to accidental breakage of the electromagnet chuck.

[0010] Preferably, the first adjusting mechanism includes a first threaded rod, a first threaded hole is provided on one side of the upper surface of the vertical plate, the first threaded rod is threaded into the inside of the first threaded hole, and the lower end of the first threaded rod is rotatably connected to the upper surface of the first adjusting plate.

[0011] With the above settings, the distance between the first adjusting plate and the vertical plate can be adjusted, and the vertical position of the support plate can be adjusted.

[0012] Preferably, the second adjusting mechanism includes a second threaded rod, a second threaded hole is provided on one side of the lower end of the first adjusting plate, the second threaded rod is threaded into the interior of the second threaded hole, and one end of the second threaded rod is rotatably connected to the second adjusting plate.

[0013] With the above settings, the distance between the second adjustment plates can be adjusted, that is, the horizontal position of the support plate can be adjusted.

[0014] Preferably, a first limiting hole is provided on the upper surface of the vertical plate and on one side of the first threaded hole, and a vertical rod is slidably sleeved inside the first limiting hole, and the lower end of the vertical rod is rotatably connected to the first adjusting plate.

[0015] With the above settings, the first adjusting plate cannot rotate with the first threaded rod, that is, it can slide stably with the first threaded rod.

[0016] Preferably, a second limiting hole is provided on the lower side wall of the second adjusting plate and on one side of the second threaded hole. A crossbar is slidably sleeved inside the second limiting hole, and one end of the crossbar is fixedly connected to the second adjusting plate.

[0017] With the above settings, the second adjusting plate cannot rotate with the second threaded rod, that is, it can slide stably with the second threaded rod.

[0018] Preferably, the cross-sections of the slide rod and the through hole are both rectangular, and the outer wall of the slide rod abuts against the inner wall of the through hole.

[0019] With the above settings, the crossbar cannot rotate, thus allowing it to slide stably within the through hole.

[0020] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0021] 1. In normal operation, the electromagnet chuck can directly attract sheet metal parts. In the event of an accidental power failure, the support plate forms a support below the sheet metal parts, so even if the electromagnet chuck loses its magnetism, the sheet metal parts will not fall off, greatly reducing the safety hazards during the use of the clamp.

[0022] 2. This utility model, by rotating the first threaded rod, drives the first adjusting plate to move up and down along the vertical rod through thread transmission, which can precisely adjust the height of the support plate to adapt to sheet metal parts of different thicknesses. By rotating the second threaded rod, the second adjusting plate is driven to slide left and right along the horizontal rod, which can adjust the horizontal distance between the support plate and the electromagnet chuck to adapt to the different positioning point requirements of the sheet metal parts.

[0023] 3. This utility model automates the entire process of sheet metal parts from positioning to processing by rapidly magnetizing / demagnetizing the electromagnet chuck. Compared to the manual adjustment mode of traditional mechanical fixtures, the positioning time for a single part is greatly shortened, significantly improving the processing cycle time.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] This utility model discloses a magnetic sheet metal quick positioning fixture.

[0032] Reference Figure 1-3 A magnetic sheet metal quick positioning fixture includes a mounting plate 1 and electromagnet chucks 2. Multiple electromagnet chucks 2 are arranged in a rectangular array and installed at the four corners of the lower surface of the mounting plate 1. A groove is formed on the upper surface of the mounting plate 1. Through holes are formed in the middle of multiple side walls of the groove. A slide rod 3 is slidably arranged inside the through holes. The cross-section of the slide rod 3 and the through holes are both rectangular. The outer wall of the slide rod 3 abuts against the inner wall of the through holes, so that the slide rod 3 cannot rotate, i.e., it can slide stably. A magnetic attraction mechanism is set inside the groove to drive the slide rod 3 to move. A vertical plate 4 is fixedly set at one end of the outer side of the slide rod 3. A first adjusting plate 5 is set at the lower side of the vertical plate 4. A first adjusting mechanism is set between the vertical plate 4 and the first adjusting plate 5 to drive the first adjusting plate 5 to move longitudinally. A second adjusting plate 6 is arranged parallel to one side of the first adjusting plate 5. A second adjusting mechanism is set between the first adjusting plate 5 and the second adjusting plate 6 to drive the second adjusting plate 6 to move horizontally. A support plate 7 is fixedly set at the lower end of the second adjusting plate 6 and on the side close to the mounting plate 1.

[0033] Reference Figure 1-3 The magnetic attraction mechanism includes an electromagnet plate 8 and an iron block 9. The electromagnet plate 8 is fixedly installed on the inner wall of the groove and at the position corresponding to the through hole. The iron block 9 is fixedly installed at the end of the slide rod 3 away from the first adjusting plate 5. A spring 10 is movably sleeved on the wall of the slide rod 3. The two ends of the spring 10 are fixedly connected to the corresponding electromagnet plate 8 and iron block 9, respectively.

[0034] Reference Figure 1-3 The first adjustment mechanism includes a first threaded rod 11. A first threaded hole is provided on one side of the upper surface of the vertical plate 4. The first threaded rod 11 is threaded into the inside of the first threaded hole. The lower end of the first threaded rod 11 is rotatably connected to the upper surface of the first adjustment plate 5. A first limiting hole is provided on the upper surface of the vertical plate 4 and on one side of the first threaded hole. A vertical rod 12 is slidably sleeved inside the first limiting hole. The lower end of the vertical rod 12 is rotatably connected to the first adjustment plate 5, so that the first adjustment plate 5 will not rotate with the first threaded rod 11, that is, it can stably follow the first threaded rod 13 to move.

[0035] Reference Figure 1-3 The second adjustment mechanism includes a second threaded rod 13. A second threaded hole is provided on one side of the lower end of the first adjustment plate 5. The second threaded rod 13 is threaded into the inside of the second threaded hole. One end of the second threaded rod 13 is rotatably connected to the second adjustment plate 6. A second limiting hole is provided on the lower side wall of the second adjustment plate 6 and on one side of the second threaded hole. A crossbar 14 is slidably sleeved inside the second limiting hole. One end of the crossbar 14 is fixedly connected to the second adjustment plate 6, so that the second adjustment plate 6 will not rotate with the second threaded rod 13, that is, it can stably slide with the second threaded rod 13.

[0036] In this utility model, firstly, according to the size of the sheet metal part, the position of the support plate 7 is adjusted by the first threaded rod 11 and the second threaded rod 13 so that the support plate 7 is located directly below the area to be processed of the sheet metal part.

[0037] When a sheet metal part needs to be gripped, the electromagnet plate 8 is energized, magnetically attracting the iron block 9. The slide rod 3 drives the vertical plate 4, the first adjusting plate 5, the second adjusting plate 6, and the support plate 7 to move towards the center of the mounting plate 1 until the support plate 7 is completely detached from the sheet metal part gripping area. At this time, the electromagnet chuck 2 is energized and magnetized, attracting the sheet metal part and lifting it to the processing position.

[0038] After the electromagnet chuck 2 attracts the sheet metal part and lifts it a certain distance, the power supply to the electromagnet plate 8 is disconnected. The spring 10 pushes the iron block 9 to move outward, and the support plate 7 returns to the position below the sheet metal part with the slide rod 3, supporting the sheet metal part to prevent it from falling.

[0039] After processing, the electromagnet chuck 2 is demagnetized, and the operator can readjust the position of the support plate 7 via the adjustment mechanism for the next gripping operation. The entire process requires no manual intervention, achieving a fully automated workflow of magnetic positioning, processing protection, and rapid changeover, effectively improving the safety and efficiency of sheet metal processing.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
