Description

Technical Field

[0001] This utility model relates to the technical field of flip-type clamps for cutting sheet metal, specifically a flip-type clamp for cutting metal sheet metal. Background Technology

[0002] Improving work efficiency is one of the main advantages of flip-over fixtures. In the traditional metal sheet cutting process, workers need to manually handle and flip the sheet, which is not only time-consuming and labor-intensive, but also prone to errors. Flip-over fixtures can automatically complete these operations, greatly reducing manual operation time and improving overall work efficiency. Ensuring operational safety is also an important advantage. In the traditional cutting process, workers directly handling the sheet poses a great safety hazard. Using flip-over fixtures can avoid this dangerous operation, reduce the occurrence of workplace accidents, and ensure worker safety.

[0003] For example, the metal sheet cutting fixture disclosed in patent application CN 211804081 U includes a front clamping platform and a rear clamping platform. The front clamping platform includes a front base, a front sliding column, and a front clamping block. The front base and the front sliding column are slidably connected left and right, and the front clamping block is movably connected to the front sliding column in the vertical direction. A material feeding drive mechanism is also connected to the front base, and the output end of the material feeding drive mechanism is drivenly connected to the front sliding column. The rear clamping platform includes a rear base, a rear sliding column, and a rear clamping block. The rear base and the rear sliding column are fixedly connected, and the rear clamping block is movably connected to the rear sliding column in the vertical direction. The front base and the rear base are spaced apart. Although it achieves automatic material feeding, after the external cutting tool cuts the external metal sheet, the material feeding drive mechanism drives the front sliding column to move to the left, pushing the cut metal sheet off the front base, thus achieving automatic continuous cutting and feeding with high production efficiency.

[0004] However, this does not solve the problem that existing flip-type clamps for cutting sheet metal are generally not conducive to quick and easy clamping and fixing of sheet metal, easy adjustment of the flip angle, easy adjustment of the position by circumferential rotation, and easy multi-degree-of-freedom control and adjustment. This greatly affects the range of rotation adjustment, the practicality of the flip-type clamp, and the efficiency of cutting metal sheet metal. Utility Model Content

[0007] Preferably, a limit rod is installed on the side wall of the second cylinder above the push rod, and the limit rod is slidably connected to the left clamping block, and a support shaft is installed at the center of the bottom end of the gimbal.

[0008] Preferably, the support shaft extends through the flip plate to the outside of the flip plate, and six sets of equally spaced support sliders are installed at the top of the flip plate outside the support shaft.

[0009] Preferably, a motor mount is installed at the bottom of the flip plate, and a servo motor is installed on the side wall of the motor mount.

[0010] Preferably, the output end of the servo motor is equipped with a rotating shaft, and a small gear is fitted on the surface of the rotating shaft.

[0013] Preferably, a rotating shaft is movably mounted on the side of the flip plate away from the first axis, and the flip plate is movably connected to the frame through the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the flip-type clamp for cutting sheet metal not only realizes the convenient and quick clamping and fixing of sheet metal, but also facilitates the convenient adjustment of the flip angle and the adjustment of the position by the circumferential rotation, and facilitates the control and adjustment of multiple degrees of freedom, increases the range of rotation adjustment, and improves the practicality of the flip-type clamp and the efficiency of cutting metal sheet metal.

[0015] (1) The push rod is driven by the second cylinder to retract inward. The push rod causes the left clamping block to retract inward under the limit of the limiting rod, thereby clamping and fixing the metal plate. The second cylinder supports the limiting rod, and the limiting rod provides sliding support for the left clamping block. The stepper motor drives the extension shaft to rotate, which in turn drives the flipping frame to rotate. With the support of the second shaft and the second support seat, the flipping frame drives the support plate, the second cylinder, the right clamping block, the left clamping block, and the metal plate to flip, so as to facilitate the flipping adjustment angle for cutting. The servo motor drives the rotating shaft to rotate, and the rotating shaft drives the small gear. The wheel rotates, the small gear drives the large gear to rotate, and the large gear drives the support shaft, gimbal, first support base, second support base, flipping frame, and metal plate to rotate and adjust in a circular motion around the support shaft. With the support of the flipping plate supporting the support slide head, the support slide head provides sliding support to the gimbal, allowing the metal plate to rotate to the position to be processed. This facilitates convenient placement, clamping, and fixing of the metal plate, enabling the flipping fixture to clamp and fix the plate quickly and easily. It also facilitates convenient adjustment of the flipping angle and allows for further adjustment of the position through circular rotation, thus improving the flexibility of the flipping fixture.

[0016] (2) The first shaft is moved by the first cylinder. The first shaft drives the flip plate to tilt at a certain angle around the rotation axis, so that the metal plate can be cut by adjusting the tilt angle. This increases the cutting range of the metal plate, realizes the flexible adjustment of the tilt angle of the flip fixture, facilitates the control and adjustment of multiple degrees of freedom, increases the range of rotation adjustment, and improves the practicality of the flip fixture and the efficiency of metal plate cutting.

A first support base 14 is mounted on the top of the gimbal 3, and a second support base 15 is mounted on the side of the top of the gimbal 3 away from the first support base 14. A stepper motor 16 is mounted on the side wall of the first support base 14, and an extension shaft 17 is mounted on the output end of the stepper motor 16. The end of the extended shaft 17 away from the stepper motor 16 is connected to the flipping frame 4. The flipping frame 4 is equipped with a second shaft 25 on the side near the second support base 15. The second shaft 25 is movably connected to the second support base 15.

[0027] Limit rods 22 are installed on the side wall of the second cylinder 20 above the push rod 18, and the limit rods 22 are slidably connected to the left clamping block 23. A support shaft 12 is installed at the center of the bottom end of the gimbal 3. The support shaft 12 extends through the flip plate 2 to the outside of the flip plate 2. Six sets of support slides 24 with equal spacing are installed at the top of the flip plate 2 outside the support shaft 12.

[0028] A motor base 8 is installed at the bottom of the flip plate 2. A servo motor 9 is installed on the side wall of the motor base 8. A rotating shaft 10 is installed at the output end of the servo motor 9. A small gear 11 is fitted on the surface of the rotating shaft 10. A large gear 13 is fitted on the surface of the support shaft 12 at the bottom of the flip plate 2. The small gear 11 and the large gear 13 mesh with each other.

[0029] When the metal sheet needs to be flipped and cut, the worker places the metal sheet between the right clamping block 21 and the left clamping block 23, and activates the two sets of second cylinders 20. Supported by the support plate 19, the second cylinders 20 drive the push rod 18 to retract inward. The push rod 18 causes the left clamping block 23 to retract inward under the limit of the limiting rod 22, thus clamping and fixing the metal sheet. The second cylinders 20 support the limiting rod 22, and the limiting rod 22 provides sliding support for the left clamping block 23. The stepper motor 16 is activated, and supported by the first support seat 14, it drives the extension shaft 17 to rotate. The extension shaft 17 drives the flipping frame 4 to rotate. Supported by the second shaft 25 and the second support seat 15, the flipping frame 4 flips the support plate 19, the second cylinders 20, the right clamping block 21, the left clamping block 23, and the metal sheet, facilitating angle adjustment by flipping. Cutting is performed by activating the servo motor 9. Supported by the motor base 8, the servo motor 9 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the small gear 11 to rotate. With the meshing of the small gear 11 and the large gear 13, the small gear 11 drives the large gear 13 to rotate. The large gear 13 drives the support shaft 12, the gimbal 3, the first support base 14, the second support base 15, the flipping frame 4, and the metal plate to rotate in a circular motion around the support shaft 12. With the support of the flipping plate 2 and the support slide head 24, the support slide head 24 provides sliding support to the gimbal 3, allowing the metal plate to rotate to the required processing position. This facilitates convenient placement and clamping of the metal plate, enabling the flipping fixture to clamp and fix the plate quickly and easily. It also facilitates convenient adjustment of the flipping angle and allows for further adjustment of the position through circular rotation, improving the flexibility of the flipping fixture.

[0030] The first cylinder 5 is symmetrically and movably installed on the side wall of the frame 1. The output end of each first cylinder 5 is equipped with a first shaft 6, and each first cylinder 5 is connected to the flip plate 2 through the first shaft 6.

[0031] A rotating shaft 7 is movably mounted on the side of the flip plate 2 away from the first shaft 6, and the flip plate 2 is movably connected to the frame 1 through the rotating shaft 7;

[0032] When cutting at different angles is required, the first cylinder 5 is opened. Supported by the frame 1, the first cylinder 5 drives the first shaft 6 to move. The first shaft 6 drives the flip plate 2 to tilt at a certain angle around the rotation shaft 7, so that the metal sheet can be cut by adjusting the tilt angle. This increases the cutting range of the metal sheet, realizes the flexible adjustment of the tilt angle of the flip fixture, facilitates multi-degree-of-freedom control and adjustment, increases the range of rotation adjustment, and improves the practicality of the flip fixture and the efficiency of metal sheet cutting.

[0033] Working principle: When the metal sheet needs to be flipped and cut, the operator places the metal sheet between the right clamping block 21 and the left clamping block 23. The second cylinder 20 drives the push rod 18 to retract inward. The push rod 18 drives the left clamping block 23 to retract inward under the limit of the limiting rod 22, thereby clamping and fixing the metal sheet. The second cylinder 20 supports the limiting rod 22, and the limiting rod 22 provides sliding support for the left clamping block 23. The stepper motor 16 drives the extension shaft 17 to rotate, which in turn drives the flipping frame 4 to rotate. Under the support of the second shaft 25 and the second support seat 15, the flipping frame 4 drives the support plate 19, the second cylinder 20, the right clamping block 21, the left clamping block 23, and the metal sheet to flip, facilitating the adjustment of the cutting angle by flipping. The servo motor 9 drives the rotating shaft 1. The rotating shaft 10 rotates, driving the small gear 11 to rotate, which in turn drives the large gear 13 to rotate. The large gear 13 then drives the support shaft 12, gimbal 3, first support base 14, second support base 15, flipping frame 4, and metal sheet to rotate in a circular motion around the support shaft 12. With the support of the flipping plate 2 and the support slide head 24, the support slide head 24 provides sliding support to the gimbal 3, allowing the metal sheet to rotate to the desired processing position. This facilitates convenient placement and clamping of the metal sheet. The first cylinder 5 drives the first shaft 6 to move, which in turn causes the flipping plate 2 to tilt at a certain angle around the rotating shaft 7, allowing the metal sheet to be cut at an adjustable angle. This increases the cutting range of the metal sheet, thus completing the use of the flipping fixture for cutting sheet metal.
