[0002] The main function of a linear motor is to convert electrical energy directly into linear motion. It can provide linear displacement with high precision and high environmental adaptability. It is widely used in situations requiring precision control, such as automated production lines, robots and CNC machine tools.

[0028] Preferably, the load translation drive device 2 can be configured as a single-axis linear motor module. The linear motor module can achieve high-precision linear motion and can provide accurate linear displacement when measuring the performance of the motor under test, thereby ensuring the accuracy of the test data.

[0029] Among them, the quick clamp 5 of the motor under test is used to quickly and stably fix the motor under test, so as to facilitate convenient installation and disassembly during the test, reduce the loading and unloading time of the motor under test, and ensure that the position of the motor under test remains stable during the test; the connecting shaft 7 is used to transmit the power provided by the load translation drive device 2 to the motor under test, and the sliding connection component 4 realizes the flexible installation and real-time data acquisition of the push-pull force sensor 6. The push-pull force sensor 6 is used to measure the push-pull force applied to the motor under test during the test. By collecting and analyzing the push-pull force data, the performance of the motor under test, such as pulling pressure and linear speed, can be effectively evaluated, providing a basis for optimized control.

[0030] like Figure 3As shown, the sliding connection assembly 4 may include a left side plate 41, a right side plate 42, two sliding rods 43, two sensor connectors 44 and two connecting clamps 45.

[0031] Among them, the two sliding rods 43 provide a guiding function, and the left side plate 41 and the right side plate 42 are both slidably connected to the two sliding rods 43 through shaft sleeves, ensuring their rapid response and stability under load.

[0032] Preferably, it can also include a grating ruler 91, a zero adjustment slide 92 and a connecting rod 93 for accurately measuring the position change of the sliding connection component 4.

[0033] Preferably, in order to prevent this, two oil pressure buffers 81 may be further included. The two oil pressure buffers 81 are respectively fixedly arranged outwardly on one side of the support base 8 facing the right side plate 42.

[0035] like Figure 5As shown, the adjustable clamp 52 may include a clamp base 521, a clamp top plate 522, two lateral clamps 523, two screws 524, two Y-shaped nuts 525 and two abutment nuts 526. The two lateral clamps 523 are respectively arranged opposite to each other and can be installed on the top surface of the clamp base 521 so as to be movable left and right. The clamp top plate 522 can be lifted and lowered on the two screws 524 through Y-shaped nuts 525 and abutment nuts 526 and is located above the two lateral clamps 523. The two abutment nuts 526 are respectively threadedly connected to the screws 524 and abut against the bottom surface of the clamp top plate 522. The two Y-shaped nuts 525 are respectively threadedly connected to the screws 524 and are located on the top surface of the clamp top plate 522.

[0036] In order to further provide a flexible adjustment mechanism, a first fixing hole 5231 can be respectively opened at both ends of the two lateral clamps 523, and a first slide bar 5211 is fixedly provided on the top surface of the clamp base 521 along its length direction, which is slidably connected to the first slide groove 5232 on the bottom surface of the two lateral clamps 523, and a number of first threaded holes 5212 corresponding to the bottom of the first fixing hole 5231 are opened on both sides of the top surface of the clamp base 521.

[0037] Among them, the adjustable clamp 52 is used to clamp the motor under test to ensure that it does not move during the test. A V-shaped structure is formed between the middle parts of the two lateral clamps 523 to match the overall structure of the motor under test. It can be flexibly adjusted in the horizontal direction to adapt to the sizes of different motors under test and has a wide range of applications.

[0038] like Figure 6 As shown, the front end fixing fixture 71 may include a U-shaped pull block coupling 711, a first conical pin 712 and a first locking screw 713. The circular back of the U-shaped pull block coupling 711 is fixedly connected to the adapter end of the connecting shaft 7. When the fisheye joint 102 at the front end of the output shaft of the motor under test 101 is aligned with the U-shaped pull block hole position of the U-shaped pull block coupling 711, the first conical pin 712 can pass through the U-shaped pull block hole position and the fisheye joint and then be threadedly connected to the first locking screw 713, thereby realizing the fixed installation of the front end of the output shaft of the motor under test 101.

[0039] Furthermore, the end fixing fixture 53 may include a U-shaped fixing seat 531, a second conical pin 532 and a second locking screw 533. The opening of the U-shaped fixing seat 531 is fixedly installed on the movable plate 51 with its opening facing upward. When the fisheye joint 102 at the tail end of the motor 101 under test is aligned with the U-shaped opening hole of the U-shaped fixing seat 531, the second conical pin 532 can pass through the U-shaped pull block hole and the fisheye joint and then be threadedly connected with the second locking screw 533, thereby realizing the fixed installation of the tail end of the motor 101 under test.

[0040] Among them, the front fixing fixture 71 and the end fixing fixture 53 ensure that the motor under test maintains a stable position during testing or operation through the design of the U-shaped pull block coupling 711 and the U-shaped fixing seat 531, as well as the combination of tapered pins and locking screws, thereby ensuring the stability and reliability of the test operation.

[0041] More specifically, second fixing holes 511 can be respectively opened on both sides of the movable plate 51, and a second slide bar 31 slidably connected to the second slide groove 512 on the bottom surface of the movable plate 51 is horizontally fixed on the test bench 3, and a plurality of second threaded holes 32 corresponding to the bottom of the second fixing holes 511 are opened on both sides of the top surface of the test bench 3.

[0042] It should be noted here that the load translation drive device 2, push-pull force sensor 6 and control buttons of this embodiment can be connected to the control panel 12, three-color light 13, industrial control computer, computer, control cabinet and other common control devices currently on the market through wires, but this embodiment does not involve structural improvements to the control equipment, which will not be repeated here.

[0043] The working principle of this embodiment for measuring the push-pull performance of the motor under test is as follows:

[0044] like Figure 7 As shown, the motor 101 to be tested is first placed between the two lateral clamps 523 of the adjustable clamp 52, and then the motor 101 to be tested is fixedly installed by the front fixing clamp 71 and the end fixing clamp 53. When the motor 101 to be tested is powered on and started, its output shaft moves laterally, driving the connecting shaft 7 to translate, and the connecting shaft 7 drives the sliding connection component 4 to translate. Since the sliding connection component 4 is connected by the load translation drive device 2, during the process of the motor 101 to be tested driving the connecting shaft 7 and the sliding connection component 4 to translate, the operator can control the output torque of the load translation drive device 2, thereby controlling the force applied by the load translation drive device 2 to the sliding connection component 4, and then controlling the force applied to the motor 101 to simulate the load condition. During the above process, the tension and compression sensor 6 can continuously measure the tension or pressure on the output shaft of the motor 101 to be tested. By collecting and analyzing the push-pull force data, the performance of the motor 101 to be tested can be effectively evaluated.

[0045] To sum up, the utility model has an integrated design, which makes the operation quick and convenient, the installation and disassembly of the motor under test simple, and it can adapt to most linear motors on the market. The joint operation of various components ensures the accurate testing of the motor under test under various load conditions, thereby improving the efficiency and reliability of the test. The integrated design makes the entire test platform efficient, accurate and stable, meeting the large-scale testing needs of enterprises.
