Description

Technical Field

[0001] The invention relates to the technical field of lift platforms, in particular to a high-precision multiple lift platform device. Background Art

[0002] The lifting platform is generally achieved by setting up a worm gear lift to achieve the lifting of the platform. When connecting multiple worm gear lifts, couplings and drive shafts are required. The existing method adopts the setting of plum blossom coupling and flat key, but due to the phase relationship, the input end of the worm gear lift must be rotated 90° to install the plum blossom coupling. This is because the shape of the plum blossom must be relative and the plum blossoms at the four corners have a 90° phase difference. In addition, the plum blossom coupling has a gap and will idle for one or two degrees before there will be tooth contact. In this way, it is difficult to keep the phase of each worm gear lift the same, and it is difficult to make the top of the internal lifting rod on the same horizontal plane. For lift platforms with higher precision requirements, it is difficult to achieve high-precision repeated positioning and lifting.

[0003] For example, in the field of battery cell testing, due to the large number and weight of battery cells, the lifting platform must have good lifting stability and good lifting accuracy, and must ensure that the contacts of each battery cell are located on the same plane to achieve contact detection of all battery cells. However, the precision control in the existing technology has not met the actual production needs and cannot achieve the expected detection effect. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a high-precision multi-lift platform device, which can solve the above-mentioned problems in the prior art.

[0005] The present invention is achieved through the following technical solutions: A high-precision multi-lift platform device of the present invention includes a reducer, and a first wheel worm lifter is arranged on the left and right sides of the reducer, and a second wheel worm lifter is arranged on the front and rear sides of the first wheel worm lifter. It is characterized in that a connecting shaft is arranged between the reducer and the first wheel worm lifter, and between the first wheel worm lifter and the second wheel worm lifter, and diaphragm couplings are arranged at both ends of the connecting shaft. By adjusting the diaphragm coupling, the connecting shaft, the input end and output end of the reducer, the input end and output end of the first wheel worm lifter, and the input end of the second wheel worm lifter have the same rotation phase.

[0006] A further technical solution is that the diaphragm coupling is dynamically connected to the two output ends of the reducer, the diaphragm coupling is dynamically connected to the input and output ends of the first worm gear lifter, the diaphragm coupling is dynamically connected to the input end of the second worm gear lifter, and a power component connected to the input end of the reducer is provided on one side of the reducer.

[0007] According to a further technical solution, the power assembly includes a power motor, which is arranged on one side of the reducer and is power-connected to an input end of the reducer.

[0008] According to a further technical solution, the first worm gear lifter and the second worm gear lifter are provided with lifting screws for lifting, and a lifting plate is provided on the upper side of the lifting screws.

[0009] A method for precise lifting using the device is as follows: the first step is to install two first-wheel worm lifters on a mounting plane, to set a diaphragm coupling at the output end of the first-wheel worm lifter, to set a second-wheel worm lifter on one side of the diaphragm coupling, to lock the diaphragm couplings at both ends of the first-wheel worm lifter, so that the connecting shafts on both sides of the output end of the first-wheel worm lifter rotate in the same phase as the output end of the first-wheel worm lifter;

[0010] The second step is to arrange the second worm gear lifter on both sides of the first worm gear lifter, and to arrange the input end of the second worm gear lifter on one side of the connecting shaft on both sides of the output end of the first worm gear lifter, and to connect and arrange a diaphragm coupling between the input end of the second worm gear lifter and the connecting shaft, first fix the diaphragm coupling to the connecting shaft, and then adjust the height of the lifting screws in the second worm gear lifter and the first worm gear lifter so that the height of the lifting disk on the second worm gear lifter is the same as the height of the lifting disk on the first worm gear lifter, and after the height of the lifting disk on the second worm gear lifter is flush with the height of the lifting disk on the first worm gear lifter, lock and fix the diaphragm coupling on one side of the input end of the second worm gear lifter;

[0011] The third step is to install a reducer between the first wheel worm lifter, firstly set diaphragm couplings at both ends of the output end of the reducer, and then set a connecting shaft on one side of the diaphragm coupling, and fix the diaphragm coupling and the connecting shaft on both sides of the output end of the reducer so that the three are in the same phase;

[0012] The fourth step is to set a diaphragm coupling between the input end of the first-wheel worm lifter and the connecting shafts on both sides of the output end of the reducer, and after adjusting the height of the lifting screws in the first-wheel worm lifters on both sides, make the lifting plates on the top of the first-wheel worm lifters on both sides be on the same plane, and then lock the diaphragm coupling set between the input end of the first-wheel worm lifter and the connecting shafts on both sides of the output end of the reducer.

[0013] The beneficial effects of the present invention are: 1. By setting up a diaphragm coupling, compared with a traditional coupling, it has good transmission rigidity. When it is specifically applied to a connecting shaft, a reducer, a first-wheel worm lifter and a second-wheel worm lifter, it can be adjusted in a free direction before it is locked, so that personnel can adjust the lifting screws in different positions so that the lifting plates are located at the same height plane, and then lock and fix them, thereby improving the accuracy of repeated positioning of the lifting screws and the lifting plates. Overall, a function of higher repeated positioning accuracy is achieved.

[0014] 2. Since a lifting platform is installed on the lifting plate, and the lifting platform is relatively large and is used to install components such as battery cells, it is necessary to arrange the reducer, the first wheel worm lifter and the second wheel worm lifter separately, and connect them through a connecting shaft and a diaphragm coupling. Overall, the lifting plates at multiple positions can be on the same horizontal plane only through adaptive adjustment of the diaphragm coupling by the installation personnel during installation, and the lifting plates can also be kept on the same horizontal plane when the lifting screw is reciprocating. This cannot be achieved with the plum blossom coupling in the prior art, and its accuracy cannot meet actual needs. The diaphragm coupling has no gap, and the accuracy of the motor's forward and reverse rotation will be higher. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting shaft 11, the input and output ends of the reducer 13, the input and output ends of the first wheel worm lifter 15, and the input end of the second wheel worm lifter 17 have the same rotation phase.

[0024] Advantageously, the power assembly includes a power motor 18 , which is disposed on one side of the reducer 13 , and the power motor 18 is power-connected to an input end of the reducer 13 .

[0025] Advantageously, a lifting screw 16 is provided inside the first worm gear lifter 15 and the second worm gear lifter 17, a lifting plate 14 is provided on the upper side of the lifting screw 16, and a lifting platform can be installed on the upper side of the lifting plate 14. The first worm gear lifter 15 and the second worm gear lifter 17 are prior art.

[0026] Advantageously, a method for performing precise lifting using the device is as follows: the first step is to install two first-wheel worm lifters 15 on a mounting plane, to set a diaphragm coupling 12 at the output end of the first-wheel worm lifter 15, to set a second-wheel worm lifter 17 on one side of the diaphragm coupling 12, to lock the diaphragm couplings 12 at both ends of the first-wheel worm lifter 15, so that the connecting shafts 11 at both sides of the output end of the first-wheel worm lifter 15 rotate in the same phase as the output end of the first-wheel worm lifter 15;

[0027] In the second step, the second worm lifter 17 is arranged on both sides of the first worm lifter 15, and the input end of the second worm lifter 17 is arranged on one side of the connecting shaft 11 on both sides of the output end of the first worm lifter 15, and the diaphragm coupling 12 is connected between the input end of the second worm lifter 17 and the connecting shaft 11. Specifically, the diaphragm coupling 12 is first fixed to the connecting shaft 11, and then the height of the lifting screw 16 in the second worm lifter 17 and the first worm lifter 15 is adjusted to make the height of the lifting plate 14 on the second worm lifter 17 and the first worm lifter 15 equal. The heights of the lifting plates 14 on the worm gear lifters 15 are the same, and a height gauge can be used for measurement and adjustment during specific adjustments. After the height of the lifting plate 14 on the second worm gear lifter 17 is flush with the height of the lifting plate 14 on the first worm gear lifter 15, the diaphragm coupling 12 on the input end side of the second worm gear lifter 17 is locked and fixed. Since a second worm gear lifter 17 is provided on each of the front and rear sides of the first worm gear lifter 15, a plane is determined by three points, and the second worm gear lifter 17 and the lifting plate 14 on the first worm gear lifter 15 form a lifting plane of the same level;

[0028] The third step is to install the reducer 13 between the first wheel worm lifter 15, firstly set the diaphragm coupling 12 at both ends of the output end of the reducer 13, and then set the connecting shaft 11 on one side of the diaphragm coupling 12, and fix the diaphragm coupling 12 and the connecting shaft 11 on both sides of the output end of the reducer 13 so that the three are in the same phase;

[0029] In the fourth step, a diaphragm coupling 12 is arranged between the input end of the first-wheel worm lifter 15 and the connecting shafts 11 on both sides of the output end of the reducer 13. By adjusting the height of the lifting screws 16 in the first-wheel worm lifters 15 on both sides, the lifting plates 14 on the top of the first-wheel worm lifters 15 on both sides are placed on the same plane. Then, the diaphragm coupling 12 arranged between the input end of the first-wheel worm lifter 15 and the connecting shafts 11 on both sides of the output end of the reducer 13 is locked. The reducer 13 can be used to transmit power of the same phase to the first-wheel worm lifter 15, so that all the lifting plates 14 can be lifted and lowered at the same time, and all the lifting plates 14 are almost located on the same plane.

[0030] After the power motor 18 starts working, it drives the reducer 13 to rotate, so that the reducer 13 passes through the diaphragm coupling 12, the connecting shaft 11, the first wheel worm lifter 15 and the second wheel worm lifter 17, so that the lifting screw 16 can be lifted and lowered simultaneously in the first wheel worm lifter 15 and the second wheel worm lifter 17, thereby realizing high-precision transmission.

[0031] The above are only specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this.
