Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular to an alternating lifting mechanism. Background Technology

[0002] Current automated production lines generally use a single clamping platform for conveying, which cannot achieve alternating operations, resulting in low production efficiency. Some automated production lines use dual clamping platforms for alternating operations. Dual clamping platforms not only need to convey the clamping platforms horizontally, but also need to lift and lower the clamping platforms vertically so that the two clamping platforms can avoid each other when moving alternately, preventing collisions and interference. However, to achieve the above actions, multiple power sources are generally required to drive the clamping platforms, and complex synchronization control is required, resulting in higher production costs.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide an alternating lifting mechanism that is simple in structure, has high production efficiency, low production cost, high synchronization, and strong practicality, so as to overcome the shortcomings of the prior art.

[0005] An alternating lifting mechanism designed for this purpose is characterized by comprising a driver, a transmission device, a guide plate, a first clamping device, and a second clamping device. The driver drives and connects to the transmission device, which in turn connects to the first clamping device and the second clamping device. A lifting guide is provided between the second clamping device and the guide plate. The driver drives the first clamping device and the second clamping device to perform horizontal alternating movements through the transmission device, so that the first clamping device and the second clamping device exchange positions. When the first clamping device and the second clamping device move to the alternating position, the second clamping device moves up and down synchronously through the lifting guide to avoid the first clamping device.

[0006] The lifting guide includes a guide member disposed on the second clamping device and a U-shaped groove section disposed on the guide plate. The guide member moves up and down along the U-shaped groove section to make the second clamping device move up and down.

[0007] The guide plate is provided with a guide groove. When the first clamping device and the second clamping device move horizontally alternately, the guide member is limited to move on the guide groove.

[0008] The guide component is a roller, which is rolled on the guide groove.

[0009] The first clamping device is provided with a clearance position. When the first clamping device and the second clamping device move to the alternation position, the second clamping device moves down synchronously and passes through the clearance position to pass through the first clamping device. After passing through the first clamping device, the second clamping device moves up synchronously.

[0010] The transmission device includes a first rack, a second rack, and a gear. The driver drives the first rack, which meshes with the gear. The gear meshes with the second rack. The first rack is connected to a second clamping device, and the second rack is connected to the first clamping device. The driver drives the first rack and the second rack to move in opposite directions, thereby causing the first clamping device and the second clamping device to move horizontally alternately.

[0011] It also includes a first buffer and a second buffer. When the first rack moves to its maximum stroke, it acts on the first buffer, and when the second rack moves to its maximum stroke, it acts on the second buffer.

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

[0013] The second clamping device includes a second clamping assembly, a fixed plate, and a first linear guide assembly. A first rack is connected to the fixed plate. The second clamping assembly is linearly slidably mounted on the fixed plate through the first linear guide assembly. The first rack drives the second clamping assembly to move horizontally through the fixed plate.

[0014] It also includes a base and a second linear guide assembly and a third linear guide assembly disposed on the base. The first clamping device is horizontally and linearly slidably disposed on the base through the second linear guide assembly, and the second clamping device is horizontally and linearly slidably disposed on the base through the third linear guide assembly.

[0015] The alternating lifting mechanism of this utility model is driven by a cylinder, which drives two sets of racks to transmit synchronously, realizing the horizontal alternating movement of the first clamping device and the second clamping device. The second clamping device is raised and lowered synchronously through a guide plate, so that the first clamping device and the second clamping device avoid each other and prevent collision interference between the two clamping devices. This structure only requires a power source to achieve the above actions, which makes the movement synchronization of the clamping devices high and does not require complex synchronization control, thereby making the operation of the alternating lifting mechanism more stable and reducing production costs.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-7 This alternating lifting mechanism includes a driver 1, a transmission device 2, a guide plate 3, a first clamping device 4, and a second clamping device 5. The driver 1 drives the transmission device 2, which in turn connects to the first clamping device 4 and the second clamping device 5. A lifting guide is provided between the second clamping device 5 and the guide plate 3. The driver 1 drives the first clamping device 4 and the second clamping device 5 to perform horizontal alternating movements through the transmission device 2, so that the first clamping device 4 and the second clamping device 5 exchange positions. When the first clamping device 4 and the second clamping device 5 move to the alternating position, the second clamping device 5 moves up and down synchronously through the lifting guide to avoid the first clamping device 4. This structure allows the first clamping device 4 and the second clamping device 5 to perform horizontal alternating movements, while the second clamping device 5 moves up and down synchronously, continuously cycling to achieve alternating conveying operations of the two clamping devices. When the first clamping device 4 and the second clamping device 5 move to the working position (e.g. Figure 3 (As shown in the image), the machining mechanism processes the workpiece on the fixture device, which is suitable for scenarios such as automated production equipment that require continuous cyclic lifting.

[0025] The lifting guide includes a guide member 6 disposed on the second clamping device 5 and a U-shaped groove section 7 disposed on the guide plate 3. The guide member 6 moves up and down along the U-shaped groove section 7 to make the second clamping device 5 move up and down.

[0027] The guide 6 is a roller, which is rolled on the guide groove 8. The use of roller rolling can reduce the friction between it and the guide groove 8, making the movement of the second clamping device 5 smoother.

[0028] The first clamping device 4 is provided with a clearance position 9. When the first clamping device 4 and the second clamping device 5 move to the alternation position, the second clamping device 5 first moves down synchronously, and then the second clamping device 5 passes through the clearance position 9 and passes through the first clamping device 4 (at this time, the second clamping device 5 moves horizontally). After passing through the first clamping device 4, the second clamping device 5 moves up synchronously, thereby allowing the second clamping device 5 to avoid the first clamping device 4.

[0029] A linear section 22 is provided at the bottom of the middle of the U-shaped groove section 7. When the second clamping device 5 passes through the first clamping device 4 through the clearance position 9, the guide 6 moves horizontally along the linear section 22.

The first rack 10 is connected to the second clamping device 5, and the second rack 11 is connected to the first clamping device 4. The driver 1 drives the first rack 10 and the second rack 11 to move horizontally in opposite directions, thereby driving the first clamping device 4 and the second clamping device 5 to move horizontally alternately. The driver 1 is a cylinder.

[0031] It also includes a first buffer 13 and a second buffer 14. When the first rack 10 moves to its maximum stroke, it acts on the first buffer 13, and when the second rack 11 moves to its maximum stroke, it acts on the second buffer 14. The first buffer 13 and the second buffer 14 are hydraulic buffers, which can reduce the impact force generated when the rack moves.

[0032] The guide groove 8 includes a U-shaped groove section 7 and linear groove sections 15 respectively disposed on both sides of the top of the U-shaped groove section 7. The guide member 6 moves horizontally along the linear groove section 15 so that the second clamping device 5 moves horizontally.
