[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figures 1-4 The utility model provides an embodiment: an auxiliary bracket for replacing a drive motor for a CNC machine tool, comprising a rectangular base 1, a square mounting plate 2 and a support module; a square mounting plate 2 for telescopically adjusting and clamping the drive motor according to the size of the drive motor is provided above the rectangular base 1, and a support module for lifting and lowering according to the distance from the drive motor to the installation position and slidingly connected to the rectangular base 1 is installed at each corner of the lower end of the square mounting plate 2, an L-shaped telescopic sleeve 203 is provided around the top of the square mounting plate 2, a rectangular telescopic plate 204 is sleeved and connected between each two groups of L-shaped telescopic sleeves 203, a positioning pin 205 is provided at the connection between the rectangular telescopic plate 204 and the L-shaped telescopic sleeve 203, and an L-shaped rubber pad 208 is installed on the inner side of the L-shaped telescopic sleeve 203.

[0023] See also Figure 2 In this embodiment, a rectangular slide groove 102 is provided on each of the two side edges above the rectangular base 1. The rectangular base 1 has two groups of rectangular slide grooves 102 with multiple groups of mounting holes 101 arranged in an array between them. The rectangular base 1 has multiple groups of first fixing holes 103 horizontally provided on one side of the rectangular slide groove 102. First, the bolts are passed through the mounting holes 101 to fix the rectangular base 1 to the ground or the machine tool to improve the stability when the drive motor is replaced.

[0024] See also Figure 3 In this embodiment, four groups of strip slides 201 are opened around the top of the square mounting plate 2, a circular limiting groove 202 is opened in the middle of the top of the square mounting plate 2, and positioning holes 206 are opened horizontally above the rectangular telescopic plate 204. The positioning pin 205 passes through the L-shaped telescopic sleeve 203 and is positioned and connected with the rectangular telescopic plate 204 through the positioning hole 206. Take out the driving motor that needs to be replaced and installed, and place it on the square mounting plate 2 along the circular limiting groove 202. Then, according to the size of the driving motor, the positioning pin 205 is adjusted and the driver is driven. The strip slider 207 drives the L-shaped telescopic sleeve 203 to slide along the strip slide 201 and connect with the square mounting plate 2, and the lower end of the L-shaped telescopic sleeve 203 is turned. A strip slider 207 is installed at the position, and a driver is provided inside the strip slider 207 (the driver model is AQMD6030BLS-E3). The strip slider 207 drives the L-shaped telescopic sleeve 203 to slide along the strip slide groove 201 and connect with the square mounting plate 2. During the sliding process, the rectangular telescopic plate 204 is contracted and adjusted along the L-shaped telescopic sleeve 203, driving the L-shaped rubber pad 208 to continuously approach and fit the drive motor to clamp and fix it. The L-shaped rubber pad 208 can increase the friction to prevent the drive motor from shaking or displacement. After confirming that the fixation is correct, the positioning pin 205 is passed through the L-shaped telescopic sleeve 203 and positioned and connected with the rectangular telescopic plate 204 through the positioning hole 206 for further fixation.

[0025] See also Figure 4 In this embodiment, the support module includes a square telescopic sleeve 301, a rectangular slider 302, a second fixing hole 303, a fixing bolt 304, a nut 305, a latch 306, a square telescopic column 307 and a round hole 308. A rectangular slider 302 is installed at the lower end of the square telescopic sleeve 301. The rectangular slider 302 is slidably connected to the rectangular base 1 along the rectangular slide 102. After the drive motor is fixed, if the drive motor needs to be fine-tuned during the replacement and installation process, the nut 305 can be loosened first, the fixing bolt 304 can be pulled out, and then the rectangular slider 302 drives the square telescopic sleeve 301 to move laterally along the rectangular slide 102. A second fixing hole 303 is opened on one side of the rectangular slider 302, and a fixing bolt 304 is passed through the middle of the second fixing hole 303 of the rectangular slider 302. The outer sleeve of the bolt 304 is provided with a nut 305. When it is moved to the appropriate position, the fixing bolt 304 is passed through the first fixing hole 103 and the second fixing hole 303 to fix it with the rectangular slider 302, and then tightened with the nut 305 to fix it. The square telescopic sleeve 301 is internally provided with a square telescopic column 307. The square telescopic column 307 and the square telescopic sleeve 301 are connected symmetrically with latches 306 on both sides. Multiple groups of circular holes 308 are linearly symmetrically provided on both sides of the square telescopic column 307. According to the distance from the drive motor to the installation position, the square telescopic column 307 drives the square mounting plate 2 to move to the appropriate height along the square telescopic sleeve 301 through the adjustment of the latch 306. After confirming that the height is correct, the latch 306 is passed through the square telescopic sleeve 301 and positioned and connected to the square telescopic column 307 through the circular hole 308.

[0026] During operation, first, bolts are passed through the mounting holes 101 to securely connect the rectangular base 1 to the ground or machine tool. Then, according to the distance between the drive motor and the mounting location, the square telescopic column 307 drives the square mounting plate 2 to move along the square telescopic sleeve 301 to a suitable height by adjusting the latch 306. After confirming that the height is correct, the latch 306 is passed through the square telescopic sleeve 301 and positioned and connected to the square telescopic column 307 through the circular hole 308.

[0027] After the height adjustment is completed, the drive motor to be replaced and installed is taken out and placed on the square mounting plate 2 along the circular limit groove 202. Then, according to the size of the drive motor, the positioning pin 205 is adjusted and the driver is driven, and the strip slider 207 drives the L-shaped telescopic sleeve 203 to slide along the strip slide groove 201 and connect with the square mounting plate 2. In this process, the rectangular telescopic plate 204 is contracted and adjusted along the L-shaped telescopic sleeve 203, driving the L-shaped rubber pad 208 to continuously approach and fit the drive motor, clamping and fixing it. The L-shaped rubber pad 208 can increase the friction force to prevent the drive motor from shaking or displacement. After confirming that it is fixed correctly, the positioning pin 205 is passed through the L-shaped telescopic sleeve 203 and positioned and connected to the rectangular telescopic plate 204 through the positioning hole 206 for further fixing.

[0028] After the drive motor is fixed, if the drive motor needs to be fine-tuned during the replacement and installation process, the nut 305 can be loosened first, and the fixing bolt 304 can be pulled out. Then the rectangular slider 302 drives the square telescopic sleeve 301 to move horizontally along the rectangular slide groove 102. When it moves to the appropriate position, the fixing bolt 304 is passed through the first fixing hole 103 and the second fixing hole 303 to fix it with the rectangular slider 302, and then tightened with the nut 305 to carry out replacement and installation.

[0029] Through the above steps, the support module is height-adjusted according to the distance between the drive motor and the installation position, which is convenient for the subsequent installation of the drive motor. Then, the drive motor that needs to be replaced and installed is taken out and placed on the square mounting plate 2. Then, the L-shaped telescopic sleeve 203 cooperates with the rectangular telescopic plate 204 to adjust the telescopic size of the drive motor and clamp it. Finally, the support module drives the fixed drive motor to move laterally along the rectangular base 1, which can slightly adjust the position of the drive motor to facilitate the assembly of the drive motor. The adjustable clamping and fixing structure can ensure that the motor maintains the correct position and angle during the installation process, which helps to reduce vibration, noise and precision reduction caused by improper installation, thereby improving the processing quality and stability of the machine tool, so as to solve the problem that most existing auxiliary brackets are fixed in one direction. Since the drive motors of different machine tools may vary greatly in size, if the auxiliary bracket is inconvenient to adjust, it may affect the precision and stability of the machine tool, and even cause damage to the motor or machine tool.
