Description

Technical Field

[0001] This invention relates to the field of lifting and rotating mechanism technology, and specifically to a high-efficiency and low-cost lifting and rotating mechanism. Background Technology

[0002] The lifting and rotating mechanism is mainly used on the conveyor rollers of various palletized workpieces in automated production lines. Its function is to lift and rotate the workpieces and materials and then automatically stop and position them at the operating station, waiting for the operator or equipment to complete the process activities at that station.

[0003] Ensure that the pallet or workpiece is transferred to the next station in a constant posture, and that the direction of the pallet and material transfer is not changed due to the operating direction required by the current process.

[0004] Currently, most domestic automakers use traditional multi-stage lifting and rotating mechanisms in their engine, transmission, electric drive, and battery assembly lines. These mechanisms involve first-stage lifting, automatic rotation, and second-stage lifting, which is time-consuming and inefficient. Furthermore, traditional lifting and rotating mechanisms require at least three power sources (two-stage cylinders + rotation) or two power sources (servo lifting + rotation). The expensive components such as servo modules, servo motors, and multi-stage cylinders not only have high manufacturing costs but also require higher usage and maintenance costs due to the additional power sources. Therefore, a high-efficiency and low-cost lifting and rotating mechanism is proposed to address these issues. Summary of the Invention

[0005] The purpose of this invention is to address the problems of traditional staged lifting and rotating mechanisms, which involve a long time consumption and low efficiency due to the first stage of lifting, automatic rotation, and the second stage of lifting. Furthermore, traditional lifting and rotating mechanisms require at least three power sources (two-stage cylinders + rotation) or two power sources (servo lifting + rotation), and their expensive components such as servo modules, servo motors, and multi-stage cylinders not only have high manufacturing costs but also require higher usage and maintenance costs due to the additional power sources. This invention provides a high-efficiency and low-cost lifting and rotating mechanism.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: A high-efficiency, low-cost lifting and rotating mechanism includes a support plate and a lifting plate. The support plate is connected to a rotating shaft, and the surface of the rotating shaft has at least one tracking groove. It also includes at least one limiting protrusion and a lifting assembly. The lifting assembly is installed on one side of the lifting plate and drives the lifting plate and the support plate upwards or downwards. The limiting protrusion is located on the side of the lifting plate away from the support plate, and its position is fixed. One of the limiting protrusions slides against the inner wall of a corresponding tracking groove, causing the support plate and the rotating shaft to rotate during the upward or downward movement.

[0007] Furthermore, each tracking groove includes a second slot that surrounds the central axis of the rotation shaft and spirals upward or downward.

[0008] Furthermore, each tracking groove also includes a first slot, which is connected to the second slot, with one limiting protrusion sliding against the inner wall of a corresponding first slot, causing the support plate and the rotating axis to move upward or downward.

[0009] Furthermore, each tracking groove also includes a third slot, the end of the second slot away from the first slot being connected to the third slot, and one of the limiting protrusions sliding on the inner wall of a corresponding third slot, causing the support plate and the rotation axis to move upward or downward.

[0010] Furthermore, a servo electric cylinder is provided on one side of the lifting plate, and the servo electric cylinder provides power to the lifting assembly to move the lifting plate upward or downward.

[0011] Furthermore, the lifting assembly includes an inner lifting rod and an outer lifting cylinder, the inner lifting rod sliding on the inner wall of the outer lifting cylinder, and the inner lifting rod being mounted on the lifting plate and / or the rotating shaft.

[0012] Furthermore, a support rod is connected to the end of the lifting outer cylinder away from the lifting plate, and a support block is connected to the end of the support rod away from the lifting outer cylinder.

[0013] Furthermore, it also includes a substrate, the surface of which has a through hole through which the rotating shaft passes. At least one fixing block is mounted on the substrate, and each fixing block is locked in combination with a corresponding limiting protrusion.

[0014] Furthermore, the surface of the lifting plate has through-holes for mounting, and at least one bearing is installed in the mounting holes. Each bearing is fitted with a corresponding mounting block, and the side of the mounting block away from the lifting plate is mounted on the support plate.

[0015] The beneficial effects of the present invention are as follows: By setting a rotating shaft, a tracking groove, and a limiting cam, the present invention uses a set of power sources (servo electric cylinders) to realize a compound operation of lifting + rotation + lifting, so as to save time and improve production efficiency, and effectively reduce manufacturing costs.

[0026] A high-efficiency and low-cost lifting and rotating mechanism includes a support plate 1 and a lifting plate 2. The support plate 1 is connected to a rotating shaft 3, and the surface of the rotating shaft 3 is provided with at least one tracking groove 4. There is at least one limiting protrusion 5 and a lifting assembly 7. The lifting assembly 7 is installed on one side of the lifting plate 2 and drives the lifting plate 2 and the support plate 1 to move up or down. The limiting protrusion 5 is located on the side of the lifting plate 2 away from the support plate 1 and its position is fixed. One of the limiting protrusions 5 slides on the inner wall of a corresponding tracking groove 4, so that the support plate 1 and the rotating shaft 3 rotate during the upward or downward movement.

[0027] like Figure 1 As shown, each tracking groove 4 includes a second slot 42, which surrounds the central axis of the rotation shaft 3 and spirals upward or downward.

[0028] like Figure 3 As shown, each tracking groove 4 also includes a first slot 41, the first slot 41 and the second slot 42 are connected, and one of the limiting protrusions 5 slides on the inner wall of the corresponding first slot 41, so that the support plate 1 and the rotating shaft 3 are displaced upward or downward.

[0029] like Figure 2 As shown, each tracking groove 4 also includes a third groove 43. The end of the second groove 42 away from the first groove 41 is connected to the third groove 43. One of the limiting protrusions 5 slides on the inner wall of the corresponding third groove 43, causing the support plate 1 and the rotating shaft 3 to move upward or downward.

[0030] like Figure 1 As shown, a servo electric cylinder 6 is provided on one side of the lifting plate 2. The servo electric cylinder 6 provides power to the lifting assembly 7 to make the lifting plate 2 move up or down. The servo electric cylinder 6 can also be replaced by a pneumatic cylinder to save more costs.

[0031] like Figure 1 As shown, the lifting assembly 7 includes an inner lifting rod 71 and an outer lifting cylinder 72. The inner lifting rod 71 slides on the inner wall of the outer lifting cylinder 72. The inner lifting rod 71 is mounted on the lifting plate 2 and / or the rotating shaft 3.

[0032] like Figure 2 As shown, a support rod 73 is connected to the end of the lifting outer cylinder 72 away from the lifting plate 2, and a support block 74 is connected to the end of the support rod 73 away from the lifting outer cylinder 72.

[0033] like Figure 1 As shown, it also includes a substrate 8, the surface of which has a through hole through which the rotating shaft 3 passes. At least one fixing block 9 is mounted on the substrate 8, and each fixing block 9 is locked in combination with a corresponding limiting protrusion 5.

[0034] like Figure 4As shown, the surface of the lifting plate 2 has through holes for mounting, and at least one bearing 102 is installed in the holes. Each bearing 102 is fitted with a corresponding mounting block 101. The side of the mounting block 101 away from the lifting plate 2 is mounted on the support plate 1.

[0035] Example 1: The entire workflow of this organization, in sequence, can be divided into the following four states: Standby state (not lifted); first stage straight-line state; rotating state; second stage straight-line state; the four working states are described in detail below:

[0036] 1. Standby state: When the stop device is in standby state, the servo electric cylinder 6 is not started and the drive cylinder is retracted. The conveyor line of the conveyed object is higher than the entire lifting and rotating mechanism, and the pallet 1 does not interfere with the flow of the conveyed object.

[0037] 2. First straight-line state: Start the servo electric cylinder 6, the inner lifting rod 71 begins to extend, driving the lifting plate 2 to rise. The lifting plate 2 drives the support plate 1 above it to rise together. At this time, the rotating shaft 3 is restricted by the tracking groove 4 and the limiting protrusion 5, and can only make straight-line upward or downward movements. The movement stroke depends on the length of the straight section of the third slot 43, that is, the length required by the process.

[0038] 3. Rotation state: When the inner lifting rod 71 continues to extend, the limiting protrusion 5 and the second slot 42 of the tracking groove 4 on the rotating shaft 3 enter a relative sliding state. At this time, the lifting plate 2 continues to rise or fall, and the support plate 1 starts to rotate with the rotating shaft 3, forming an independent multi-layer action between them.

[0039] 4. Second straight-line state: When the lifting inner rod 71 continues to extend, the rotating shaft 3 enters the second straight-line state. At this time, the limiting protrusion 5 slides relative to the inner wall of the first slot 41. The length of the stroke is determined according to the stroke of the lifting inner rod 71 and the length of the straight-line section of the cam groove.

[0040] In addition, multiple tracking grooves 4 can be made on the rotating shaft 3. Only 1 to 2 of the tracking grooves 4 are used during operation. The extra tracking grooves 4 on the rotating shaft 3 can be reserved for future use, which increases the service life of the rotating shaft 3 by 2 to 3 times and greatly reduces the cost of use and maintenance.

[0041] Example 2: Figure 3 The example shown is the case of embodiment 1, but there is another case in which the inner lifting rod 71 and the rotating shaft 3 are indirectly connected. During the rotation of the rotating shaft 3, it will not change or contradict the linear upward or downward movement of the inner lifting rod 71. In this case, the inner lifting rod 71 is not connected to the lifting plate 2, and the entire mechanism can be without the lifting plate 2.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
