Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 - Figure 5 , a high-voltage servo motor speed measurement device, including a fixed base 1, a limit rod 2 is installed on the top of the fixed base 1, a fixed plate 3 is installed on the top of the fixed base 1, a driving toothed plate 4 is provided on the outer wall of the limit rod 2, a moving plate 5 is movably sleeved on the outer wall of the limit rod 2, a driving box 6 is fixedly assembled on the outer wall of the moving plate 5, a driving screw 7 is rotatably connected in the inner cavity of the driving box 6, a driving gear 8 is rotatably connected in the inner cavity of the driving box 6, a transmission rod 9 is fixedly assembled on the outer wall of the driving gear 8, a driven box 10 is fixedly assembled on the outer wall of the moving plate 5, a transmission gear 11 is rotatably connected in the inner cavity of the driven box 10, a protective bottom shell 12 is installed on the top of the fixed base 1, a protective top shell 13 is rotatably connected to the outer wall of the protective bottom shell 12, a display screen 14 is installed on the top of the fixed base 1, a motor to be measured 15 is installed in the inner cavity of the fixed plate 3, a fixing ring 16 is fixedly assembled on the top of the fixed base 1, a permanent magnet 17 is installed in the inner cavity of the fixing ring 16, and a motor rotor 18 is rotatably connected in the inner cavity of the fixing ring 16.

[0022] By providing the fixed plate 3 and the moving plate 5 on the top of the fixed base 1, and the driving box 6, the driving screw 7 and the driving gear 8 on the outer wall of the moving plate 5, the moving plate 5 can be driven under the action of the driving screw 7 and the driving gear 8, so that the outer wall of the moving plate 5 approaches the outer wall of the fixed plate 3, thereby fixing the motor to be measured 15 during the approaching process of the fixed plate 3 and the moving plate 5.

[0023] In a preferred implementation mode: the number of the limit rods 2 is two, and the two limit rods 2 are respectively installed on the top of the fixed base 1.

[0024] By means of two limit rods 2 installed on the top of the fixed base 1, stable limitation of the moving plate 5 is achieved under the action of the two limit rods 2, enabling the moving plate 5 to only move left and right along the outer wall of the limit rods 2, thereby better realizing the fixing effect on the motor 15 to be measured.

[0025] In a preferred embodiment: The outer wall of the driving screw rod 7 meshes with the outer wall of the driving gear 8, and the outer wall of the driving gear 8 meshes with the outer wall of the driving tooth plate 4.

[0026] By means of the driving screw rod 7 and the driving gear 8 arranged in the inner cavity of the driving box 6, when the driving screw rod 7 rotates, the outer wall of the driving screw rod 7 will drive the outer wall of the driving gear 8, causing the driving gear 8 to rotate. Furthermore, during the rotation of the driving gear 8, the moving plate 5 is pushed, enabling the moving plate 5 to move back and forth along the outer wall of the limit rod 2.

[0027] In a preferred embodiment: The outer wall of the transmission rod 9 passes through the outer wall of the driven box 10 and is connected to the transmission gear 11, and the outer wall of the transmission gear 11 meshes with the outer wall of the limit rod 2.

[0028] By arranging the transmission rod 9 on the outer wall of the driving gear 8 and connecting the outer wall of the transmission rod 9 to the transmission gear 11, the driving gear 8 and the transmission gear 11 can rotate synchronously. Furthermore, when the driving screw rod 7 rotates, the driving gear 8 and the transmission gear 11 can be simultaneously driven to rotate under the action of the driving screw rod 7, thereby driving the moving plate 5.

[0029] In a preferred embodiment: Both the protective top shell 13 and the protective bottom shell 12 are made of stainless steel, and the fixed ring 16 is electrically connected to the display screen 14.

[0030] By installing the protective bottom shell 12 and the protective top shell 13 on the top of the fixed base 1, the fixed ring 16 and the motor rotor 18 are wrapped under the action of the protective bottom shell 12 and the protective top shell 13. Thus, when the motor 15 to be measured drives the motor rotor 18 to rotate at a high speed, good protection can be achieved under the action of the protective bottom shell 12 and the protective top shell 13, avoiding safety risks when the motor rotor 18 rotates in the inner cavity of the fixed ring 16.

[0031] In a preferred embodiment: Buffer pads are installed on the inner walls of the fixed plate 3 and the moving plate 5, and the buffer pads are all made of natural rubber.

[0032] By means of the buffer pads provided on the inner walls of the fixed plate 3 and the moving plate 5, when the fixed plate 3 and the moving plate 5 are attached to the outer wall of the motor 15 to be measured, the friction force between them and the outer wall of the motor 15 to be measured can be increased under the action of the buffer pads, so as to achieve a better fixing effect and ensure that the motor 15 to be measured can stably perform the speed measurement work.

[0033] Working principle: During the use of the above-mentioned device, when it is necessary to use the device to measure the speed of the motor, the motor is placed on the top of the fixed base 1. Then, the driving screw 7 is rotated. Under the action of the driving screw 7, the driving gear 8 rotates, so that the outer wall of the driving gear 8 moves back and forth along the outer wall of the limiting rod 2, thereby realizing the pushing of the moving plate 5. During the rotation of the driving gear 8, under the action of the transmission rod 9, the transmission gear 11 rotates synchronously with the driving gear 8, so as to realize the joint driving of the moving plate 5 under the action of the driving gear 8 and the transmission gear 11, so that the outer wall of the moving plate 5 can contact the outer wall of the motor 15 to be measured faster, thus achieving the fixing effect on the motor 15 to be measured. Then, the power output shaft of the motor 15 to be measured is inserted into the inner cavity of the motor rotor 18, and the driving of the motor rotor 18 can be started, so that the motor rotor 18 rotates at a high speed in the inner cavity of the fixed ring 16, and a voltage is generated under the action of the motor rotor 18, the fixed ring 16 and the permanent magnet 17. The faster the rotation speed, the greater the voltage, and the voltage is fed back to the outer wall of the display screen 14, so that the voltage fluctuation can be observed on the display screen 14, thereby realizing the measurement of the rotation speed of the motor 15 to be measured.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
