Description

Technical Field

[0001] The utility model relates to the technical field of lifting operations, in particular to an automatic synchronous lifting device. Background Art

[0002] The statements in this section merely provide background technology related to the present invention and do not necessarily constitute prior art.

[0003] Lifting mechanisms are often used in automation equipment. Lifting mechanisms are usually driven by pneumatic cylinders or electric cylinders to achieve up and down movement of the mechanism. When the lifting mechanism needs to set multiple stop positions during the rising and falling process, an electric cylinder (motor servo module) is generally used to drive it.

[0004] At present, in general, a lifting mechanism is driven by a single electric cylinder connected to a certain position of the mechanism, but for a large lifting mechanism, it is usually necessary to use two electric cylinders connected to the left and right symmetrical positions of the mechanism to drive the mechanism to rise and fall.

[0005] Therefore, the prior art has at least the following technical problems:

[0006] (1) When the lifting mechanism uses two electric cylinders for lifting control, there may be differences in the synchronization of the two electric cylinders, resulting in jamming or deviation during the lifting process of the mechanism.

[0007] (2) Since two electric cylinders are used, the cost is relatively high. Utility Model Content

[0008] In order to solve the above problems, the utility model designs a device with relatively low cost and good lifting synchronization, which uses a motor to transmit power to two jacks for synchronous action, thereby reducing operation and hardware costs and enhancing the stability of the lifting mechanism.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] An automatic synchronous lifting device comprises at least: a first lifting platform, a second lifting platform, two jacks, a guide shaft, a connecting rod and a motor;

[0011] The first lifting platform is located directly above the second lifting platform, and the platform is arranged in a square shape;

[0012] The second lifting platform is located directly below the first lifting platform and is parallel to the first lifting platform, and the platform is arranged in a hexagonal shape;

[0013] The jack and the guide shaft are inserted through the first lifting platform and fixedly connected to the upper surface of the second lifting platform;

[0014] The motor is arranged on the first lifting platform and connected to the jacks through a connecting rod to transmit power to the two jacks to achieve synchronous action of the two jacks;

[0015] The jack is provided with a gear screw mechanism inside, and the middle gear screw of the jack is raised and lowered to drive the second lifting platform below.

[0016] The motor is arranged on the first lifting platform and connected to the jacks through a connecting rod to transmit power to the two jacks to achieve synchronous action of the two jacks, specifically including:

[0017] A T-type reducer is provided at the lower end of the motor, and the motor is connected to the T-type reducer;

[0018] The ports on both sides of the T-type reducer are respectively connected to the connecting rods on both sides;

[0019] The connecting rods on both sides of the T-type reducer extend in opposite directions along the side of the table where the motor is located to the two corners of the table, and are connected to the first L-type reducer and the second L-type reducer;

[0020] The first L-shaped reducer and the second L-shaped reducer are respectively connected to the first jack and the second jack through a connecting rod along the side of the table where the jacks are located.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] Existing large-scale lifting mechanisms usually use two electric cylinders to provide power. The synchronization of the two electric cylinders is affected by factors such as the response speed of the motor control system, and is prone to asynchrony. The lifting mechanism of the utility model connects a motor with two jacks, and can transmit power to the two jacks at the same time through a mechanical connection to achieve synchronous action, thereby solving the problem of poor lifting synchronization of traditional lifting mechanisms, improving the stability of the lifting mechanism during the rising process, and avoiding jamming or offset.

[0023] The lifting mechanism of the utility model is driven by a motor, thereby reducing operation and equipment costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The first lifting platform 1 is located directly above the second lifting platform 2, and the table top is set in a rectangular shape. In this embodiment, a square is preferred. The second lifting platform 2 is located directly below the first lifting platform 1 and is parallel to the first lifting platform 1, and the table top is set in a hexagonal shape. The first jack 301, the second jack 302 and the guide shaft 9 are inserted through the first lifting platform 1 and fixedly connected to the upper surface of the second lifting platform 2. A linear bearing 10 is provided between the guide shaft 9 and the first lifting platform 1. The linear bearing 10 is nested on the guide shaft 9 and plays a connection and positioning function. The guide shaft 9 is used to guide the lifting of the second lifting platform 2.

[0034] In this embodiment, the top surface of the first lifting platform 1 is viewed from above as a reference system for the positional relationship between the first jack 301, the second jack 302 and the guide shaft 9. The top surface of the first lifting platform 1 has four sides (four sides), wherein the first jack 301 and the second jack 302 are respectively arranged at the middle positions on the two opposite sides of the top surface of the first lifting platform 1 (near the middle positions of the two relative sides of the top surface), and four guide shafts 9 are provided, of which two are arranged on both sides of the first jack 301, and the other two are arranged on both sides of the second jack 302.

[0035] In this embodiment, the motor 4 is arranged on the first lifting platform 1, and the power is transmitted to the two jacks 301 and 302 through the connecting rod 5, so as to realize the synchronous action of the two jacks 301 and 302. The top of the first lifting platform 1 is also overlooked as a reference system for judging the positional relationship of the motor 4. Specifically, the motor 4 is arranged in the middle position of any adjacent side (side length) of the first jack 301 or the second jack 302.

[0036] As a specific implementation, the motor 4 transmits power to the two jacks 301 and 302 through the connecting rod 5 to achieve the synchronous action of the two jacks 301 and 302, which specifically includes:

[0037] A T-type reducer 8 is provided at the lower end of the motor 4, and the motor is connected to the T-type reducer; the ports on both sides of the T-type reducer 8 are respectively connected to the connecting rods 5 on both sides, and the connecting rods 5 on both sides of the T-type reducer 8 extend in opposite directions along one side of the table where the motor 4 is located to the two corners of the table of the first lifting platform 1, and are connected to the first L-type reducer 701 and the second L-type reducer 702; further, the first L-type reducer 701 and the second L-type reducer 702 are respectively connected to the first jack 301 and the second jack 302 through the connecting rod 5 along one side of the table where the jack is located; couplings 6 are provided at both ends of each connecting rod 5, and the couplings 6 are used to connect different mechanisms to achieve torque transmission.

[0038] Among them, the motor 4 is used to provide a power source, and the T-type reducer 8, the first L-type reducer 701, and the second L-type reducer 702 are mainly used to reduce the power of the motor through the gear with a small number of teeth on the input shaft of the reducer meshing with the large gear on the output shaft to achieve the purpose of deceleration, and then the output shaft transmits the power to other mechanisms. In this embodiment, the T-type reducer 8 divides the power provided by the motor 4 into two paths, and then transfers the power to two power lifting jacks through the connecting rod, the coupling and the L-type reducer, and uses the jacks to realize the lifting and lowering of the mechanism.

[0039] The above-mentioned power is transferred to two power lifting jacks, and the jacks are used to realize the lifting of the mechanism, which specifically includes: a gear screw mechanism is provided inside the jack, the motor 4 transmits power to the jack, and the intermediate gear screw of the jack is lifted and lowered, thereby realizing the up and down movement of the second lifting platform 2 below, and the second lifting platform 2 drives the working equipment to move up and down. The working equipment 12 in this embodiment is a welding gun, which can realize welding of objects in the vertical direction.

[0040] Further, such as Figure 3 As shown, an auxiliary support positioning mechanism is provided in the middle position of each connecting rod 5, and the auxiliary support positioning mechanism includes a ball bearing 13 and a fixed seat 14. The connecting rod 5 passes through the ball bearing 13, and the fixed seat 14 is fixed on the surface of the first lifting platform 1. The auxiliary support positioning mechanism is used for the connecting rod 5 to play an auxiliary support positioning function to prevent the connecting rod 5 from shaking and deviating during the rotation process.
