Description

Technical Field

[0001] This utility model relates to the field of sheet metal clamping technology, specifically to a metal sheet metal clamping device. Background Technology

[0002] In the field of metal processing, the processing of sheet metal is a crucial step. To improve processing efficiency and precision, sheet metal fixtures have emerged to securely clamp and position sheet metal, ensuring stability during processes such as cutting, bending, and welding. However, existing sheet metal fixtures often face difficulties in leveling and repositioning after the workpiece has been flipped.

[0003] Existing metal sheet fixtures come in various designs and functions, but they generally lack an efficient flipping and resetting mechanism. During machining, when it's necessary to flip the workpiece to the other side for processing, operators typically need to manually adjust the fixture's position and angle to achieve quick leveling and resetting of the workpiece. This process is not only time-consuming and labor-intensive but also prone to introducing errors, affecting machining accuracy and efficiency.

[0004] Chinese Patent Publication No. CN221363461U discloses a metal sheet welding fixture. A frame is mounted above a base plate. Two sets of support columns are symmetrically installed on the top two edges of the base plate. Two sets of electric turntables are symmetrically installed on the opposite side walls of the two sets of support columns. A transmission rod is connected to the output end of each electric turntable, and the other end of the transmission rod is connected to the frame. A locking post causes a slider to move a slide table and a placement table on a sliding groove, allowing metal sheets of different specifications to be freely spliced ​​together. The locking post and groove allow the slider to be fixed in any position, enabling the fixture to adapt to the splicing of metal sheets of various sizes, improving the practicality of the device and increasing welding efficiency.

[0005] However, in practical use, the aforementioned structure struggles to quickly reset and level the workpiece after clamping and flipping it. Specifically, it lacks an efficient mechanism to rapidly adjust the workpiece's position and orientation to ensure it quickly returns to a horizontal or predetermined position after flipping. This deficiency forces workers to spend considerable time manually leveling the workpiece in subsequent processes, reducing efficiency and potentially introducing errors due to improper operation, thus affecting machining accuracy.

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0029] See Figures 1-3 As shown, a metal sheet clamp includes a base 1, a fixed plate 2 disposed on top of the base 1, a sliding seat 3 disposed on top of the base 1 and located beside the fixed plate 2, and a rotating shaft 4 rotatably disposed between the sliding seat 3 and the fixed plate 2. The clamp also includes a leveling mechanism 5 and a clamping mechanism 6. The leveling mechanism 5 is disposed on top of the sliding seat 3 and located outside the rotating shaft 4. The leveling mechanism 5 includes a rotating part 51, a positioning rod 52, and an abutting part 53. The rotating part 51 is rotatably disposed on top of the sliding seat 3 and located outside the rotating shaft 4. The positioning rod 52 is disposed on top of the sliding seat 3 and located beside the rotating part 51. The abutting part 53 is rotatably disposed outside the positioning rod 52. When the abutting part 53 rotates, it can abut against the bottom of the rotating part 51 and restrict the rotation of the rotating part 51. The clamping mechanism 6 is disposed outside the rotating shaft 4 and located on top of the base 1.

[0030] The rotating part 51 is mounted on the top of the sliding seat 3 via bearings and is fixedly connected to the rotating shaft 4. When the rotating part 51 rotates, it can drive the rotating shaft 4 to rotate synchronously. A threaded rod 31 is rotatably provided on the end face of the fixed plate 2 and is threadedly connected to the sliding seat 3. When the threaded rod 31 rotates, it can drive the sliding seat 3 to move closer to or away from the fixed plate 2. When the screw 64 rotates, it can drive the sliding seat 3 to move, and when the rotating part 51 rotates, it can drive the clamping mechanism 6 to rotate, so that the clamping mechanism 6 can rotate the clamped workpiece. After the workpiece rotates, the clamping mechanism 6 and the rotating part 51 need to be reset and leveled. Rotate the rotating part 51 until the rotating part 51 contacts the abutment part 53 and stops rotating. After contact, the rotating part 51 stops rotating and resets and levels, ensuring that the workpiece can quickly and accurately return to the initial position and achieve leveling after clamping and rotation.

[0031] See Figures 2-5As shown, the leveling mechanism 5 also includes a sliding part 54 and a connecting rod 55; the top of the sliding seat 3 is provided with a vertical limiting groove 32, and the vertical limiting groove 32 is located on the side of the rotating shaft 4; the connecting rod 55 is provided on the outside of the abutting part 53, one end of the connecting rod 55 is rotatably connected to the sliding part 54, and the other end of the connecting rod 55 is rotatably connected to the abutting part 53.

[0032] When the rotating part 51 rotates, it will come into contact with the abutting part 53. When in contact, the abutting part 53 can rotate along the positioning rod 52. When the abutting part 53 rotates, the sliding part 54 can be pulled down and slid along the vertical limiting groove 32 by the connecting rod 55.

[0033] See Figures 4-6 As shown, the leveling mechanism 5 also includes a mounting plate 56 and a telescopic spring 57; the mounting plate 56 is disposed on the top of the sliding seat 3 and above the abutment part 53; the telescopic spring 57 is disposed on the top of the mounting plate 56 and above the base 1, one end of the telescopic spring 57 is fixedly connected to the mounting plate 56, and the other end of the telescopic spring 57 is fixedly connected to the sliding part 54.

[0034] When the sliding part 54 slides down along the vertical limiting groove 32, it can drive the extension spring 57 to be stretched.

[0035] See Figure 5 and Figure 6 As shown, the leveling mechanism 5 also includes a positioning pin 58 and a limiting rod 59; a positioning hole is provided on the top of the sliding seat 3; the positioning pin 58 is slidably disposed on the top of the sliding part 54 and located beside the positioning hole, and the positioning pin 58 can slide on the sliding part 54 and abut against the positioning hole; the limiting rod 59 is disposed on the top of the sliding seat 3 and located beside the abutting part 53.

[0036] When the sliding part 54 descends and the rotating part 51 rotates, the positioning pin 58 is first pulled outwards from the sliding part 54 until it disengages from the outside of the positioning hole. Then, when the rotating part 51 rotates, it can drive the sliding part 54 to descend via the connecting rod 55. After the workpiece is processed and the rotating part 51 needs to be leveled, the sliding part 54 is pulled and driven into an upward sliding state. When the sliding part 54 rises, the connecting rod 55 pulls the abutment part 53 into a rotating state until the abutment part 53 contacts the limiting rod 59, at which point the rotation stops. Then, the positioning pin 58 is inserted into the positioning hole through the sliding part 54, thus fixing the sliding part 54 onto the sliding seat 3. Then, the worker continues to rotate the rotating part 51 until it contacts the abutment part 53 and stops rotating, achieving rapid reset and leveling of the rotating part 51 and the clamping mechanism 6.

[0037] See Figures 2-8As shown, the leveling mechanism 5 also includes a level 591; the level 591 has a pair and is respectively disposed on the top of the rotating part 51, and the level 591 is located on the side of the abutment part 53.

[0038] When rotating the rotating part 51 for leveling, the level 591 can help workers observe the rotation and reset status of the rotating part 51.

[0039] See Figure 7 and Figure 8 As shown, the clamping mechanism 6 includes a rotating part 61 and a locking block 62; the rotating part 61 has a pair of rotating parts that are respectively rotatably disposed outside the rotating shaft 4; the end faces of the fixing plate 2 and the sliding seat 3 are provided with circular grooves 611 for the rotating part 61 to rotate; the locking block 62 is rotatably disposed outside the rotating part 61, and the locking block 62 can slide inside the circular groove 611.

[0040] When clamping a workpiece, firstly, the rotating part 51 is rotated, and the abutment part 53 brings the rotating part 51 and the rotating shaft 4 into a horizontal position. Then, the threaded rod 31 is rotated, driving the sliding seat 3 to slide. During this process, the sliding seat 3 can drive the rotating part 61 to move synchronously. Since the rotating part 61 is fixedly connected to the rotating shaft 4, and the rotating part 61 slides with the circular groove 611 through the snap-fit ​​block 62, this allows the rotating part 61 to move synchronously when the sliding seat 3 slides, and also allows the rotating part 61 to rotate simultaneously when the rotating shaft 4 rotates. This achieves the adjustment of the position of the sliding seat 3 and the rotating part 61.

[0041] See Figure 8 As shown, the clamping mechanism 6 also includes a square plate 63, a screw 64, and a support plate 65; the square plate 63 is disposed on the top of the rotating part 61 and above the base 1; the screw 64 is rotatably disposed on the top of the square plate 63; and the support plate 65 is disposed on the right side of the rotating part 61 and below the screw 64.

[0042] When the sliding seat 3 drives the rotating part 61 to move, the workpiece is first placed above the support plate 65, and then the screw 64 is rotated.

[0043] See Figure 8 As shown, the clamping mechanism 6 also includes a rubber block 66; the rubber block 66 is disposed at the bottom of the screw 64 and is circular.

[0044] When the screw 64 rotates, it can drive the rubber block 66 to rotate synchronously until the rubber block 66 abuts the workpiece against the top of the support plate 65, thus realizing the clamping of workpieces of different sizes.

[0045] Working principle: When the rotating part 51 rotates, it contacts the abutting part 53. At this time, the abutting part 53 can rotate along the positioning rod 52 and drive the sliding part 54 to descend within the vertical limiting groove 32 through the connecting rod 55. The descent of the sliding part 54 stretches the telescopic spring 57. During this process, the positioning pin 58 needs to be pulled out from the outside of the sliding part 54 until it disengages from the positioning hole to allow the sliding part 54 to move freely. After the workpiece is processed, the rotating part 51 needs to be leveled. At this time, the sliding part 54 is pulled up to make it rise, and the abutting part 53 is driven to rotate through the connecting rod 55 until the abutting part 53 contacts the limiting rod 59 and stops. Then, the positioning pin 58 is inserted into the positioning hole of the sliding part 54 to fix the sliding part 54 on the sliding seat 3. After that, the rotating part 51 continues to rotate until it contacts the abutting part 53 and stops, realizing the rapid reset and leveling of the rotating part 51 and the clamping mechanism 6. During this process, the level 591 can help observe the rotation and reset status of the rotating part 51. When clamping a workpiece, first rotate the rotating part 51 and make it horizontal with the rotating shaft 4 through the abutment part 53. Then rotate the threaded rod 31 to drive the sliding seat 3 to slide. Since the rotating part 61 is fixedly connected to the rotating shaft 4 and slides with the circular groove 611 through the snap-fit ​​block 62, the sliding of the sliding seat 3 will drive the rotating part 61 to move synchronously. At the same time, the rotation of the rotating shaft 4 will also drive the rotating part 61 to rotate, thereby realizing the adjustment of the position of the sliding seat 3 and the rotating part 61. After the sliding seat 3 drives the rotating part 61 to move to the appropriate position, place the workpiece on the support plate 65, and then rotate the screw 64. The rotation of the screw 64 will drive the rubber block 66 to rotate synchronously until the rubber block 66 presses the workpiece against the top of the support plate 65, realizing the clamping of workpieces of different sizes.

[0046] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
