Description

A high-precision spindle motor-assisted drag test platform Technical Field

[0001] This utility model relates to the field of CNC machine tools, and in particular to a high-precision spindle motor drag test platform. Background Technology

[0002] With the rapid development of the CNC machine tool industry, the demand for high-precision motors is increasing, making motor mounting platforms, as key platforms in motor testing or experimentation, increasingly important. Furthermore, as motor speeds and power / torque continue to rise, the requirements for the concentricity of the motor and its mounting platform are also becoming increasingly stringent.

[0003] The existing solution involves directly fixing the L-shaped adapter plate of the motor onto the sheet metal frame. However, during testing, the machine is often repeatedly pulled apart. The connection method of the L-shaped adapter plate results in poor platform concentricity, causing significant vibration during rotation, thus making it impossible to obtain experimental data at higher speeds. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a high-precision spindle motor mounting test platform. It improves the accuracy of the mounting platform through a slide rail, enabling high-speed, high-precision motor load testing. Furthermore, it uses a sleeve to quickly detect the concentricity of the motors on both sides, achieving rapid alignment.

[0005] According to one aspect of the present invention, a high-precision spindle motor drag test platform is provided, comprising a base platform, two left-right extending slide rails are installed on the front and rear sides of the base platform, two motors and a torque sensor are slidably mounted on the two slide rails, and the torque sensor is located between the two motors.

[0006] Both of the motors have drive shafts facing the torque sensor and are on the same horizontal line as the torque sensor's shaft. At least one of the motors has a sleeve fitted on one end of its drive shaft, and the other end of the sleeve can be fitted onto the shaft.

[0007] Multiple sliding and fixed limiting blocks are slidably installed in the middle of the base platform. Each limiting block is located on the left and / or right side of each motor and can limit the movement of the motor.

[0008] In some embodiments, two L-shaped sliding brackets and a sliding support are slidably mounted on the two slide rails, with two motors respectively mounted on the two L-shaped sliding brackets, and the torque sensor mounted on the top of the sliding support. The advantage is that it describes the specific mounting method of the two motors and the sliding support.

[0009] In some embodiments, the two L-shaped sliding frames and the two motors are arranged in opposite directions. The advantage is that the arrangement of the two L-shaped sliding frames and the two motors is further described.

[0010] In some embodiments, two left-right extending outer sliding grooves are formed on the front and rear sides of the base, and an outer cover is slidably mounted on both outer sliding grooves. The outer cover can slide to enclose each of the drive shafts and the torque sensor inside it. The advantage of this is that by setting the outer cover, it is possible to prevent the rotating parts from flying off in the event of excessive experimental torque or an accident, thereby avoiding safety hazards.

[0011] In some embodiments, a central groove extending laterally is formed in the middle of the base, and each of the limiting blocks is respectively installed in the central groove. The advantage is that the central groove allows the limiting blocks to slide and be fixed in place.

[0012] In some embodiments, the top of each limiting block is higher than the bottom of each L-shaped sliding frame. This is advantageous because it allows each limiting block to limit the movement of both the L-shaped sliding frame and the motor. Attached Figure Description

[0014] Figure 2 is a partial structural schematic diagram of a high-precision spindle motor drag test platform shown in Figure 1.

[0015] Figure 3 is a schematic diagram of the structure related to the base platform shown in Figure 1.

[0016] In the diagram: base 1, motor 2, torque sensor 3, sleeve 4, limit block 5, slide rail 11, L-shaped sliding frame 12, sliding bracket 13, outer slide groove 14, center slide groove 15, drive shaft 21, outer cover 22, rotating shaft 31. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] As shown in Figures 1-3, the experimental platform includes a base 1. Two parallel sliding rails 11 are installed on both sides (front and back sides) of the base 1. Two L-shaped sliding frames 12 and one sliding bracket 13 are slidably installed on the two sliding rails 11. The two L-shaped sliding frames 12 are arranged opposite to each other, and the sliding bracket 13 is located between the two L-shaped sliding frames 12. Both the two L-shaped sliding frames 12 and the sliding bracket 13 can slide along the two sliding rails 11.

[0019] Two motors 2 are mounted on two L-shaped sliding brackets 12, respectively, and the two motors 2 are arranged in opposite directions. At the same time, a torque sensor 3 is mounted on the top of the sliding bracket 13. The torque sensor 3 has a horizontal rotating shaft 31, and the drive shafts 21 of the two motors 2 face the torque sensor 3 and are both located on the same horizontal line as the rotating shaft 31. This ensures that the repeated pulling and connecting of the motors 2 will not produce deviation and guarantees excellent concentricity.

[0020] In addition, a sleeve 4 is fitted onto one end of the drive shaft 21 of at least one motor 2. When the motor 2 moves, the other end of the sleeve 4 can be used to fit the rotating shaft 31 of the torque sensor 3, thereby completing the docking of the motor 2 and the torque sensor 3 and achieving the effect of quickly checking concentricity.

[0021] Preferably, two left-right extending outer sliding grooves 14 are formed on the front and rear sides of the base platform, and an outer cover 22 is slidably installed on the two outer sliding grooves 14. The outer cover 22 can slide between the two motors 2 to cover the drive shafts 21 of the two motors 2 and the torque sensor 3 inside, so as to prevent the rotating body from flying out in case of excessive experimental torque or accident, thereby avoiding safety hazards.

[0022] Furthermore, a central sliding groove 15 extending laterally is formed in the middle of the base platform 1, and multiple sliding and fixed limiting blocks 5 are installed on the central sliding groove 15. Each limiting block 5 is located on the left and / or right side of each L-shaped sliding frame 12, with its top end higher than the bottom end of each L-shaped sliding frame 12. Therefore, after each motor 2 moves to the appropriate position, the limiting blocks 5 can be used to limit and fix each L-shaped sliding frame 12, preventing even slight movements of the L-shaped sliding frame 12 from amplifying vibrations and affecting the test.

[0023] When using this platform, slide the two L-shaped sliding frames 12 until the drive shafts 21 of the two motors 2 are connected to the rotating shaft 31 of the torque sensor 3 through the sleeve 4. Then, use the limit blocks 5 to limit and fix the two L-shaped sliding frames 12. Then, the main shaft motor drag test can be carried out in conjunction with other instruments and circuits.

[0024] The high-precision spindle motor-assisted experimental platform of this utility model has the following beneficial effects:

[0025] 1. By using slide rails, the repeated pulling and connecting of the motor will not produce deviation, thus ensuring excellent concentricity;

[0026] 2. By using front and rear limit blocks, it is ensured that the sliding frame will not move even slightly, thus amplifying the vibration and affecting the test;

[0027] 3. By using a sleeve to align the motor's drive shaft with the torque sensor's rotating shaft, concentricity can be quickly checked, avoiding excessive dial indicator usage that could affect the time.

[0028] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
