Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a manipulator conveying device of an automatic welding machine. Background Art

[0002] Automatic welding machine is an automatic welding machine based on motor control technology, single chip microcomputer control technology, PLC control technology and numerical control technology.

[0003] The known authorized patent application number is: CN202223565702.3, which discloses a manipulator transporting device for a welding machine. Its background technology proposes the problem that "the iron block needs to be clamped during mechanical transport. Currently, the clamping mostly requires an electric telescopic rod or a drive motor to achieve clamping, which is costly; the sliding part is easily bumped by hard objects during use, which affects subsequent use after the bump." Therefore, the technical solution to this problem is "including: a welding machine base, an adjustment part, a lifting part and a clamping part; the welding machine base is fixed on a workbench; the adjustment part consists of a sliding seat, a sliding block, a connecting plate, a threaded rod and a drive motor, the sliding seat is fixedly connected to the top surface of the welding machine base, and a sliding block is slidably connected in the sliding seat" and so on.

[0004] However, in the implementation of related technologies, it was found that the above technical solution has the following problems: although it achieves the effects of automatic clamping and shielding protection through the provided technical solution, it is not convenient to lock and limit the clamping block when in use. It uses the elastic force of the spring to clamp the workpiece, and when the clamped workpiece is moved, the workpiece will be squeezed laterally by the force to squeeze the clamping block to move, which can easily cause the clamping block and the workpiece to slip and loosen, thereby reducing the clamping stability and conveying effect of the workpiece.

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figure 1 - Figure 5The present invention provides a manipulator transport device for an automated welding machine, comprising: a base 1; two mounting plates 2 symmetrically arranged on the base 1, the mounting plates 2 being lifted and moved laterally to adjust their positions by an adjusting mechanism arranged on the base 1; two clamping blocks 3 symmetrically arranged between the two mounting plates 2, the two clamping blocks 3 being movable relative to each other by an elastic mechanism arranged on the mounting plate 2, wherein the bottom of the clamping block 3 is an arc structure; a tooth plate 4 fixedly connected to one side of the clamping block 3 and slidably connected to the mounting plate 2; a fixing block 5 fixedly mounted on one side of the mounting plate 2; a movable rod 6 slidingly connected to the fixing block 5; a tooth block 7 fixedly connected to the bottom end of the movable rod 6 and meshing with the tooth plate 4; and a fixing mechanism arranged on the fixing block 5 for limiting and locking the movable rod 6.

[0026] The fixing mechanism includes a ring-shaped electromagnet 8 fixedly mounted on the top of the fixing block 5 and a permanent magnet ring 9 fixedly connected to the top surface of the movable rod 6 and magnetically connected to the electromagnet 8 .

[0027] The technical solution provided by this embodiment is as follows: when in use, the position of the clamping block 3 can be adjusted through the adjustment mechanism so that it is aligned with the workpiece, and then the adjustment mechanism drives the mounting plate 2 and the clamping block 3 to move down again, so that the clamping block 3 contacts the workpiece, and the clamping block 3 is squeezed by the workpiece to move and compress the elastic mechanism, and automatically clamps the workpiece under the action of the elastic mechanism, and at the same time, when the clamping block 3 moves, it can drive the tooth plate 4 to move synchronously, and utilize the mutual squeezing action of the inclined surface of the tooth block 7 to make the tooth block 7 drive the movable rod 6 to move up, when the clamping After the holding block 3 clamps the workpiece, the movable rod 6 moves down and resets due to gravity, driving the tooth block 7 to engage with the tooth plate 4. At the same time, the electromagnet 8 is energized to attract the permanent magnet ring 9, so that the movable rod 6 applies force downward to drive the tooth block 7 and the tooth plate 4 to be locked and fixed, so that the clamping block 3 is fixed and cannot move. Therefore, the clamping block 3 is locked and limited, avoiding the situation where the clamping block 3 moves and separates from the workpiece when the workpiece moves, ensuring the continuous clamping effect of the clamping block 3 on the workpiece, and effectively improving the clamping stability and conveying effect and efficiency.

[0028] Preferably, the elastic mechanism includes two limit rods 10 symmetrically fixedly mounted on one side of the clamping block 3 and slidingly connected to the mounting plate 2, and a spring 11 sleeved on the surface of the limit rod 10 and connected to the mounting plate 2 and the clamping block 3 at both ends respectively. A slot is provided on the mounting plate 2 for the tooth plate 4 to slide through.

[0029] Specifically: when clamping the workpiece, the clamping block 3 is driven downward by the adjustment mechanism to contact the workpiece. Since the bottom end of the clamping block 3 is an arc structure, as the clamping block 3 moves downward, it is squeezed by the workpiece and can move the compression spring 11 to both sides, and drive the limit rod 10 to slide. When the clamping block 3 moves downward to be parallel to the side of the workpiece, the workpiece can be automatically clamped under the action of the spring 11, which improves the convenience of use.

[0030] Preferably, the adjustment mechanism includes a transverse sliding component provided on the base 1 for moving the clamped workpiece, and a vertical sliding component provided on the transverse sliding component for lifting and lowering the clamping block 3 .

[0031] The transverse sliding component includes a sliding shell 12 fixedly mounted on the top of the base 1, a screw rod 13 rotatably connected between the two sides of the inner wall of the sliding shell 12, a sliding block 14 threadedly connected to the surface of the screw rod 13 and slidingly connected to the sliding shell 12, and a motor 15 fixedly mounted on one end face of the sliding shell 12, the output end of the motor 15 movably passes through the sliding shell 12 and is connected to the screw rod 13.

[0032] The vertical sliding component includes a connecting block 16 fixedly installed on the top of the sliding block 14, an electric push rod 17 fixedly installed at the top center of the connecting block 16, two guide rods 18 symmetrically fixedly installed on both sides of the top of the connecting block 16, and an L-shaped plate 19 fixedly connected to the output end of the electric push rod 17 and slidingly connected to the guide rod 18. The two mounting plates 2 are symmetrically fixedly installed at the bottom of the horizontal section of the L-shaped plate 19.

[0033] Specifically: when transporting the workpiece, the electric push rod 17 drives the L-shaped plate 19 to move downward along the surface of the guide rod 18, so that the two clamping blocks 3 are in contact with the workpiece. At the same time, as the clamping block 3 moves, the clamping block 3 can automatically clamp the workpiece through the elastic force of the spring 11. The motor 15 then drives the screw rod 13 to rotate, so that the sliding block 14 slides in the sliding shell 12, thereby driving the clamped workpiece to move, achieving the purpose of moving and transporting. After moving to the appropriate position, the electric push rod 17 drives the clamping block 3 to move up and reset to separate it from the workpiece.

[0034] Example 2

[0035] Based on the first embodiment, in this embodiment: multiple rows of anti-skid protrusions 20 are fixedly mounted on the opposite surfaces of the two clamping blocks 3. The anti-skid protrusions 20 are made of rubber and have an arc-shaped cross section.

[0036] The technical solution provided by this embodiment is: by setting the anti-slip protrusion 20, the contact friction between the clamping block 3 and the workpiece can be increased, thereby facilitating further improving the clamping effect, and the anti-slip protrusion 20 is made of rubber material, which can buffer the clamping force and avoid the influence of excessive clamping force on the workpiece.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
