Compared with the prior art, the lifting nut is rotated, the lifting nut is always in contact with the first guide sleeve, and the lifting screw moves up and down relative to the lifting nut, so that the lifting top plate can move up and down, the height of the lifting top plate can be accurately adjusted within a certain range, and the height of the motor dynamometer is adjusted.
Description
Technical Field
The utility model relates to a lifting platform for a motor dynamometer, and belongs to the technical field of motor testing.
Background
A motor dynamometer is a device that measures mechanical torque. The essence of the device is a DC generator with a stator capable of rotating, when torque is input to a rotating shaft, the movable stator deflects due to the counter torque, and the torque is conveniently and accurately measured by using a scale and a lever arm arranged on the stator. If the rotation speed is measured at the same time, the mechanical power can be calculated. The motor dynamometer is suitable for testing the performance of a motor in a laboratory, is also suitable for a production line and is used for detecting the delivery of motor products. However, the height of the motor dynamometer is often required to be adjusted during testing, and the height of the motor dynamometer is increased by adding a wood board to the bottom of the motor dynamometer at present, which is very troublesome.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a lifting platform for a motor dynamometer, which is convenient for adjusting the height, aiming at the defects of the prior art.
The technical scheme adopted by the utility model for realizing the purpose is as follows:
the lifting platform for the motor dynamometer comprises a lifting bottom plate and a lifting top plate, wherein a first guide sleeve is installed on the lifting bottom plate, the first guide sleeve is hollow and internally provided with a lifting screw, a lifting nut is sleeved on the lifting screw, the bottom of the lifting nut is always in contact with the top surface of the first guide sleeve, and the lifting top plate is fixed to the top of the lifting screw.
As a further optimization of the above technical solution: and rotating the lifting nut, enabling the lifting screw to move up and down relative to the lifting nut, and enabling the lifting top plate to start moving up and down relative to the lifting bottom plate.
As a further optimization of the above technical solution: the lifting bottom plate is further provided with a plurality of second guide sleeves, lifting guide posts are arranged in the second guide sleeves, the lifting top plate is fixed to the tops of the lifting guide posts, positioning holes are formed in the second guide sleeves, positioning screws are arranged in the positioning holes, the lifting guide posts are fixed in the second guide sleeves by screwing down the positioning screws, and at the moment, the lifting top plate stops moving up and down.
As a further optimization of the above technical solution: the second guide sleeves are four and are respectively positioned at four corners of the lifting bottom plate.
Compared with the prior art, the lifting nut is rotated, and the lifting nut is always contacted with the first guide sleeve, so that the lifting screw moves up and down relative to the lifting nut, the lifting top plate can move up and down, the height of the lifting top plate can be accurately adjusted within a certain range, the height of the motor dynamometer is adjusted, and the motor dynamometer is convenient and quick; a lifting guide post and a second guide sleeve are arranged to guide the lifting process, and the lifting guide post plays a role in supporting a lifting top plate; the positioning screw is used for positioning the lifting guide post.

Detailed Description
The utility model is further described with reference to the following figures and detailed description. As shown in fig. 1-2, the lifting table for the motor dynamometer comprises a lifting bottom plate 1 and a lifting top plate 2, and the motor dynamometer is placed on the lifting top plate 2. Install first uide bushing 3 on the lifting bottom plate 1, first uide bushing 3 cavity is and its inside lifting screw 4 that is provided with, and the cover is equipped with lifting nut 5 on the lifting screw 4, and lifting nut 5's bottom contacts with the top surface of first uide bushing 3 all the time, and lifting top plate 2 passes through set screw to be fixed at lifting screw 4's top. Rotatory lifting nut 5 because lifting nut 5 contacts with first uide bushing 3 all the time, and lifting screw 4 reciprocates for lifting nut 5 to realize reciprocating of lift roof 2, can be at the height of certain extent accurate adjustment lift roof, thereby the height of adjustment motor dynamometer machine, convenient and fast.
In the above technical scheme: a plurality of second guide sleeves 6 are further installed on the lifting bottom plate 1, and four second guide sleeves 6 are arranged in the embodiment and are respectively located at four corners of the lifting bottom plate 1. A lifting guide post 7 is arranged in the second guide sleeve 6, and the lifting top plate 2 is fixed at the top of the lifting guide post 7 through a fixing screw. The side wall of the second guide sleeve 6 is provided with a positioning hole 61, a positioning screw is arranged in the positioning hole 61, the lifting guide post 7 is fixed in the second guide sleeve 6 by screwing the positioning screw, and at the moment, the lifting top plate 2 is positioned and stops moving up and down. The positioning screw is unscrewed, the lifting screw 4 drives the lifting top plate 2 to move up and down, the lifting guide post 7 moves up and down along with the lifting top plate 2, and the lifting guide post 7 and the second guide sleeve 6 are matched to play a role in guiding the lifting process of the lifting top plate 2. After the lifting is finished, the positioning screws are screwed again, and the lifting guide columns 7 play a role in supporting the lifting top plate 2.
The foregoing detailed description of the preferred embodiments of the utility model has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concept of the present invention should fall within the scope of the present invention.
