Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a sheet metal flipping mechanism. Background Technology

[0002] In existing sheet metal processing, the weight is generally large, so when it needs to be flipped, most of the time a clamping plate or jaw structure is used in conjunction. However, in actual production, sheet metal materials may be non-standard structures, so it is difficult for clamping plates or jaws to guarantee the stability of clamping.

[0003] Of course, existing clamping structures that use other methods, such as Chinese Patent 202510314257.2, use an electric telescopic rod to achieve clamping, but in practice, the fulcrum of this design is subjected to a large force, which can easily affect the stability of the clamping.

[0004] Therefore, in order to solve the problem of the inconvenience of flipping during daily sheet metal processing (such as welding, spraying, gluing, etc.). Utility Model Content

[0005] The main purpose of this utility model is to propose a sheet metal flipping mechanism, which aims to solve the problem of large and heavy workpieces being difficult to flip in daily processing by coordinating lifting devices, clamping devices, flipping devices and fixtures, thereby improving production stability and applicability.

[0006] To achieve the above objectives, this utility model proposes a sheet metal flipping mechanism, comprising:

[0007] Erecting the frame;

[0008] A vertical moving device, comprising at least two vertical guide rails disposed on the front wall of the upright, a vertical slider disposed on the vertical guide rails, and a vertical driving device for driving the vertical slider.

[0009] A horizontally arranged support plate is provided between the two vertical sliders;

[0010] A bidirectional clamping device, comprising a transverse guide rail mounted on a support plate, two sets of transverse sliders mounted on the transverse guide rail, and a clamping drive device for driving the transverse sliders to move.

[0011] The horizontal slider extends forward to have a clamping arm, and the clamping drive device is provided with a synchronous adjustment structure to make the two clamping arms move synchronously.

[0012] The two clamping drive devices respectively drive the two clamping arms to move between positions close to each other or positions far apart from each other;

[0013] The clamp is detachably mounted on the front wall of the clamping arm. A synchronizing rod is provided between the two clamps, and the two ends of the synchronizing rod are slidably connected to the guide holes of the clamps.

[0014] A rotating device is provided on the outer side of any one of the clamping arms. When the rotating device drives any one of the clamping arms to rotate, the other clamping arm rotates synchronously through a synchronizing rod.

[0015] In the actual design, a vertical moving device is used to lift the sheet metal, thereby meeting different processing requirements and also achieving tilting and avoidance. In addition, a dual clamping drive device and a synchronous adjustment structure are used to achieve mechanized bidirectional clamping, which can provide greater clamping force. Furthermore, through the cooperation of the fixture and the synchronous rod, the fixture can clamp the sheet metal parts, such as plate-shaped structures, block-shaped structures, and box-shaped structures, thereby ensuring the processing stability of large sheet metal parts.

[0034] like Figures 1 to 5 As shown, a sheet metal flipping mechanism includes:

[0035] Frame 1;

[0036] The vertical moving device 2 includes at least two vertical guide rails 21 disposed on the front wall of the upright 1, a vertical slider 22 disposed on the vertical guide rails 21, and a vertical driving device 3 for driving the vertical slider 22.

[0037] A horizontally arranged support plate 20 is provided between the two vertical sliders 22;

[0038] The bidirectional clamping device includes a transverse guide rail 71 mounted on the support plate 20, two sets of transverse sliders 72 mounted on the transverse guide rail 71, and a clamping drive device for driving the transverse sliders to move.

[0039] The horizontal slider extends forward to have a clamping arm, and the clamping drive device is provided with a synchronous adjustment structure to make the two clamping arms move synchronously.

[0040] The two clamping drive devices respectively drive the two clamping arms to move between positions close to each other or positions far apart from each other;

[0041] A clamp 8 is detachably mounted on the front wall of the clamping arm. A synchronizing rod 81 is provided between the two clamps 8, and the two ends of the synchronizing rod 81 are slidably connected to the guide holes 80 of the clamps 8.

[0042] Rotating device 9 is located on the outer side of any one of the clamping arms. When the rotating device 9 drives any one of the clamping arms to rotate, the other clamping arm rotates synchronously through the synchronizing rod 81.

[0043] In the actual design, a vertical moving device 2 is used to lift the sheet metal, thereby meeting different processing requirements and also achieving flipping and avoidance. In addition, a dual clamping drive device and a synchronous adjustment structure are used to achieve mechanized bidirectional clamping, which can provide greater clamping force. Furthermore, through the cooperation of the fixture 8 and the synchronous rod 81, the fixture 8 can clamp the sheet metal parts, such as plate-shaped structures, block-shaped structures, and box-shaped structures, thereby ensuring the processing stability of large sheet metal parts.

[0044] Specifically, the vertical drive device 3 is a vertical telescopic hydraulic cylinder or a vertical lead screw assembly.

[0045] The top of the support frame 1 is equipped with a guide gear 30, and the guide gear 30 is equipped with a balance chain 31. One end of the balance chain 31 is connected to the support plate 20, and the other end is connected to a balance block 32. Unlike existing designs, the movement of the support plate 20 is achieved through a vertical drive device 3, in which the vertical telescopic hydraulic cylinder has a larger load capacity, and the vertical screw pair has higher stroke accuracy.

[0046] The additional structure extending outward from the clamping arm, in conjunction with the balance block 32, improves the stability of the flipping mechanism and eliminates the reaction force generated during flipping, thereby enhancing safety in use.

[0047] To further ensure safety, a locking device can be added, such as a latch and a limit device on the guide gear 30. Motor control is preferred, meaning the vertical drive device 3 works in conjunction with a motor.

[0048] In this embodiment of the utility model, the top end of the support plate 20 is provided with a plurality of connectors for connecting with the vertical drive device 3 and the balance chain 31.

[0049] Specifically, the clamping device is provided in two sets, located above and below the clamping arm, respectively.

[0050] In this embodiment of the invention, the clamping device includes a first telescopic motor 51 and a second telescopic motor 52, and the clamping arm includes a first clamping arm 41 and a second clamping arm 42.

[0051] The rear end of the first telescopic motor 51 is oscillatingly mounted on the first clamping arm 41, and the drive end of the first telescopic motor 51 is pivotally connected to the second clamping arm 42.

[0052] The rear end of the first telescopic motor 51 is oscillatingly mounted on the second clamping arm 42. The drive end of the second telescopic motor 52 is pivotally connected to the first clamping arm 41, thereby realizing the double clamping effect, ensuring synchronous movement and stable clamping. Even if a single telescopic motor fails, there will be no sudden separation. Furthermore, a secondary locking structure can be set to further ensure the stability of the clamp.

[0053] Specifically, the synchronization adjustment structure includes a first rack and a second rack respectively disposed on the opposite walls of the first clamping arm 41 and the second clamping arm 42, and a synchronization gear is provided between the first rack and the second rack.

[0054] This ensures the synchronous movement between the two;

[0055] The clamping arm has a bent structure.

[0056] In this embodiment of the invention, the rotating device 9 is equipped with a reduction gearbox, thereby achieving a greater driving torque.

[0057] Of course, in another embodiment, rotating devices can be provided at both ends, and synchronous flipping between the two clamping arms can be achieved by a synchronous drive device.

[0058] Specifically, the guide hole 80 is provided with a linear bearing, and the synchronizing rod 81 extends into the linear bearing. Specifically, the synchronizing rod 81 is provided with locking pins at both ends to form a limiting position.

[0059] In this embodiment of the utility model, the clamp 8 includes a main body and a limiting groove 82 recessed in the main body. The limiting groove 82 is provided with a limiting structure that is adapted to the shape of the sheet metal. Of course, it can be replaced according to actual needs.

[0060] Specifically, the limiting structure is a limiting rod 83, which thereby achieves the limiting of the sheet metal parts.

[0061] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
