Description

Technical Field

[0001] This utility model relates to the technical field of plate positioning, and in particular to a center positioning fixture. Background Technology

[0002] In sheet metal processing, it is necessary to flip the flat plate so that the front and back sides can be processed separately. In existing processing production lines or assembly lines, a robotic arm is used to grab and flip the sheet metal during the production process.

[0003] The problem is that during the conveyor belt transport of the sheet material on the production line, the vibration of the equipment causes the sheet material to constantly change position on the conveyor belt. This requires the robotic arm to spend a lot of time positioning the sheet material for gripping, resulting in insufficient overall flipping efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a centering fixture to address the problem of the inability to quickly locate the position of the board material, so as to ensure that the board material can be accurately placed into the gripping area.

[0005] A center positioning fixture includes a transport frame, a transport belt mounted laterally on the transport frame, and a box mounted longitudinally on the transport frame. First mounting plates that can slide centered are mounted on both sides of the top of the box. First support members are mounted on the first mounting plates, and first connecting rods are mounted on both first support members. First clamping seats for holding workpieces are mounted at the ends of both first connecting rods. A driving component is installed inside the box to drive the two first mounting plates to center displacement.

[0006] As a preferred embodiment, a first slider is installed at the bottom of the first mounting plate, and a first slide rail that cooperates with the first slider is installed at the top of the box.

[0007] As a preferred embodiment, the first support member includes two support seats mounted on the top surface of the first mounting plate, and a first connecting rod is inserted through the two support seats, with the end of the first connecting rod fixedly connected to the side of the first clamp.

[0008] As a preferred embodiment, a threaded hole is provided on any one of the support seats, and a first fastening bolt is threaded into the threaded hole, with one end of the first fastening bolt passing through the threaded hole abutting against the surface of the first connecting rod body.

[0009] As a preferred embodiment, the first connecting rod has a positioning hole that mates with the first fastening bolt.

[0010] In a preferred embodiment, the driving component includes a first through slot formed at the top of the housing. A threaded rod is horizontally installed inside the housing, with both ends of the threaded rod rotatably connected to the inner wall of the housing. A worm gear is fixedly connected to the middle of the threaded rod. A worm for driving the worm gear is installed inside the housing, with both ends of the worm rotatably connected to the inner wall of the housing. A first connecting block is provided between the threaded rod and two first mounting plates. The top of the first connecting block passes through the first through slot and is fixedly connected to the bottom of the first mounting plate. The bottom of the first connecting block is threadedly connected to the threaded rod.

[0011] As a preferred embodiment, a geared motor for driving the worm gear rotation is installed on the side of the housing.

[0012] The advantages of this utility model are:

[0013] The board to be processed needs to be flipped over by a flipping device so that the top and bottom surfaces of the board can be processed separately. Before flipping the board, the centering and alignment device can ensure that the board is accurately centered so that the suction cup assembly in the subsequent flipping device will not deviate from the center position of the board and the board will be evenly stressed after being picked up.

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model.

[0021] like Figures 1-3 As shown,

[0022] As an optional embodiment,

[0023] A center positioning fixture includes a transport frame 1, a transport belt 2 mounted laterally on the transport frame 1, and a box 10 mounted longitudinally on the transport frame 1. The top two sides of the box 10 are equipped with first mounting plates 3 that can slide in a centered manner. First support members 4 are mounted on the first mounting plates 3. First connecting rods 7 are mounted on both first support members 4. First clamping seats 5 for clamping workpieces are mounted at the ends of both first connecting rods 7. A driving component is installed inside the box 10. The driving component is used to drive the two first mounting plates 3 to move in a centered manner.

[0024] Specifically, the sheet material to be processed needs to be flipped using a flipping device to facilitate separate processing of the top and bottom surfaces. Before flipping, the sheet material needs to be centered to ensure that it does not deviate from the center after being picked up by the suction cup assembly in the flipping device, which could cause the sheet material to fall off due to unstable force after being picked up. Based on this, a centering and alignment device is designed. This centering fixture ensures that the sheet material is accurately placed in the center of the transport frame 1, and then the conveyor belt 2 transports the sheet material to the flipping area. During the centering process, the drive component pushes the first mounting plates 3 located on both sides of the conveyor belt 2 to move closer simultaneously. The halfway point between the two first mounting plates 3 is located at the center of the conveyor belt 2, ensuring that the distance between the two first mounting plates 3 is equidistant from the conveyor belt 2. Thus, even after the distance between the two first mounting plates 3 changes, their distance from the center point of the conveyor belt 2 remains consistent. The first clamps 5 on the first mounting plates 3, connected by the first support member 4, are attached to the outside of the workpiece. The first clamps 5 on the front and rear sides are located on the front and rear sides of the workpiece, respectively. During the movement of the first mounting plates 3, the two first clamps 5 on the front and rear sides drive the workpiece to be centered and positioned, achieving rapid positioning.

[0025] Based on the above implementation method, the improvements are as follows, specifically as follows: Figure 2 As shown,

[0026] The bottom of the first mounting plate 3 is equipped with a first slider 8, and the top of the box 10 is equipped with a first slide rail 9 that cooperates with the first slider 8. The first slide rail 9 is fixed on the box 10, and the box 10 is fixed on the transport frame 1. The first slider 8 is fixed to the bottom of the first mounting plate 3, and the first slider 8 and the first slide rail 9 slide in cooperation to ensure that the first mounting plate 3 is oriented and will not deviate during the movement.

[0027] like Figure 2 As shown, the first support member 4 includes two support seats installed on the top surface of the first mounting plate 3. A first connecting rod 7 is inserted through the two support seats. The end of the first connecting rod 7 is fixedly connected to the side of the first clamp 5. The two support seats are fixedly connected to the first mounting plate 3. At the same time, the first connecting rod 7 passes through the two support seats and is fixedly connected to the side of the first clamp 5, so that the first clamp 5 can be fixed.

[0028] like Figure 2 As shown, a threaded hole is provided on any one of the support seats, and a first fastening bolt 6 is threaded into the threaded hole. One end of the first fastening bolt 6 passes through the threaded hole and abuts against the surface of the first connecting rod 7. Subsequently, the surface of the first connecting rod 7 can be tightly abutted against one of the support seats by the fastening bolt engaging with the threaded hole.

[0029] like Figure 2As shown, the first connecting rod 7 has a positioning hole 71 that mates with the first fastening bolt 6. After the first fastening bolt 6 passes through the threaded hole, it abuts against the positioning hole 71 on the surface of the first connecting rod 7, thereby restricting the rotation of the first connecting rod 7 on the support.

[0030] like Figure 3 As shown, the driving component can use an existing centering driving module, or a driving part capable of centering displacement can be designed, and the specific structure of the driving component is as follows:

[0031] The enclosure includes a first through slot 1001 on the top of the housing 10, a threaded rod 12 horizontally installed inside the housing 10, with both ends of the threaded rod 12 rotatably connected to the inner wall of the housing 10, a worm gear 13 fixedly connected to the middle of the threaded rod 12, a worm 14 for driving the worm gear 13 to rotate installed inside the housing 10, with both ends of the worm 14 rotatably connected to the inner wall of the housing 10, a first connecting block 11 between the threaded rod 12 and each of the two first mounting plates 3, the top of the first connecting block 11 passing through the first through slot 1001 and fixedly connected to the bottom of the first mounting plate 3, and the bottom of the first connecting block 11 threadedly connected to the threaded rod 12; and a reduction motor 15 for driving the worm 14 to rotate is installed on the side of the housing 10.

[0032] The threaded rods 12, which are laterally distributed in the housing 10, and the worm gears 14, which are longitudinally distributed in the housing 10, are arranged in a cross shape. The threaded rods 12 are equipped with worm wheels 13 that mesh with the worm gears 14. The reduction motor 15 can drive the worm gears 14 to rotate, thereby ultimately driving the threaded rods 12 to rotate. Two first connecting blocks 11 are installed on the threaded rods 12, one in front and one in back, and both first connecting blocks 11 cooperate with the threaded rods 12. Therefore, when the threaded rods 12 rotate, the two first connecting blocks 11 move closer to each other or further away from each other. The first through slot 1001 can be used to limit the movable position of the two first connecting blocks 11 inserted therein, so as to avoid collision when the two first clamps 5 are centered and displaced.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. 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 patent should be determined by the appended claims.
