Description

Technical Field

[0001] The invention relates to the technical field of automated production, and in particular to an alternating lifting mechanism. Background Art

[0002] At present, automated production lines generally use a single fixture platform for conveying, which cannot achieve alternating operation, resulting in low production efficiency. Some automated production lines use double fixture platforms for alternating operation. The double fixture platform not only needs to be transported horizontally, but also needs to be lifted up and down so that the two fixture platforms can avoid each other when alternating, preventing the two fixture platforms from colliding and interfering. However, to achieve the above actions, multiple power sources are generally required to drive the fixture platform to move, and complex synchronous control is required, resulting in high production costs.

[0003] Therefore, further improvements are necessary. Summary of the invention

[0006] The lifting guide part comprises a guide member arranged on the second clamp device and a U-shaped groove section arranged on the guide plate. The guide member moves up and down along the U-shaped groove section to make the second clamp device move up and down.

[0007] The guide plate is provided with a guide groove. When the first clamp device and the second clamp device make horizontal alternating movements, the guide piece moves in a limited position on the guide groove.

[0008] The guide member is a roller, and the roller is rotatably arranged on the guide groove.

[0009] The first clamp device is provided with an avoidance position. When the first clamp device and the second clamp device move to the alternating position, the second clamp device performs a synchronous descending movement, and the second clamp device passes through the first clamp device through the avoidance position. After passing through the first clamp device, the second clamp device performs a synchronous ascending movement.

[0010] The transmission device includes a first rack, a second rack and a gear. The driver drives the first rack, the first rack and the gear are meshed with each other, the gear and the second rack are meshed with each other, the first rack is connected to the second clamp device, and the second rack is connected to the first clamp device. The driver drives the first rack and the second rack to move in opposite directions, thereby driving the first clamp device and the second clamp device to move horizontally alternately.

[0011] The first and second buffers are also included. When the first rack moves to a maximum stroke, the first buffer acts on the first buffer. When the second rack moves to a maximum stroke, the second buffer acts on the second buffer.

[0012] The guide groove comprises a U-shaped groove section and linear groove sections respectively arranged on both sides of the U-shaped groove section, and the guide member moves horizontally along the linear groove sections to make the second clamp device move horizontally.

[0013] The second clamp device includes a second clamp assembly, a fixed plate and a first linear guide assembly. The first rack is connected to the fixed plate. The second clamp assembly is linearly slid up and down on the fixed plate through the first linear guide assembly. The first rack drives the second clamp assembly to move horizontally through the fixed plate.

The first clamp device is arranged on the base through horizontal linear sliding through the second linear guide assembly, and the second clamp device is arranged on the base through horizontal linear sliding through the third linear guide assembly.

[0015] The alternating lifting mechanism of the present invention is driven by one cylinder, which drives two sets of racks for synchronous transmission, realizes the horizontal alternating movement of the first clamp device and the second clamp device, and synchronously lifts the second clamp device through the guide plate, so that the first clamp device and the second clamp device avoid each other to prevent the two clamp devices from colliding and interfering. The structure only needs one power source to realize the above-mentioned actions, so that the movement synchronization of the clamp device is high, and no complicated synchronous control is required, so that the operation of the alternating lifting mechanism is more stable, while reducing the production cost.
