Description

Technical Field

[0001] This utility model relates to the field of lead screw testing technology, specifically a vertical lead screw testing device. Background Technology

[0002] Vertical lead screws are one of the core components in the field of mechanical transmission. They are widely used in high-end equipment such as CNC machine tools, industrial robots, and aerospace equipment. Their function is to convert rotary motion into precise linear motion. The accuracy, rigidity, and stability of the lead screw directly affect the positioning accuracy, machining quality, and service life of the equipment. After long-term use, lead screws will wear out, so it is necessary to test their performance using a testing device.

[0003] When using a vertical lead screw testing device to test the wear of the lead screw, it is necessary to check whether the threads on the outside of the lead screw are intact. During installation, the position of the clamping assembly needs to be manually adjusted to connect with the test thread sleeve. This method is cumbersome, increases labor costs, takes up a long time, and reduces testing efficiency. Utility Model Content

[0023] Please see Figure 1-4This utility model provides a technical solution for a vertical lead screw testing device: A vertical lead screw testing device includes a base 1, a housing 2, a controller 3, a testing device 4, and an adjusting device 5. The housing 2 is located at the top of the base 1, the controller 3 is located at the front end of the housing 2, and the testing device 4 is located at the top of the base 1. The testing device 4 includes a support column 41, a guide rail 42, and a clamping assembly 43.

The linkage device 5 includes a fixed rod 51, an adjusting rod 52, a sprocket 53, a chain 54, a movable block 55, a limit block 56, an infrared ranging sensor 57, and a movable mechanism 58. Both ends of the fixed rod 51 are rotatably connected to the inside of the support column 41 via bearing seats. One end of the adjusting rod 52 is rotatably connected to the inside of the support column 41 via a bearing seat. Two sets of sprockets 53 are provided, fixed to the outside of the fixed rod 51 and the outside of the adjusting rod 52, respectively. The chain 54 is located on the outside of the sprockets 53 and is drively connected to them. The movable block 55 is fixed to the outside of the chain 54, and one end of the movable block 55 is connected to the clamping assembly 43. The outer side is fixedly connected, the limiting block 56 is fixed inside the support column 41, the infrared ranging sensor 57 is installed on the top of the clamping assembly 43, the movable mechanism 58 is set on the outer side of the support column 41, and the movable mechanism 58 is used to control the rotation of the adjusting rod 52. The detection device 4 also includes a support plate 44, a cylinder 45, a bellows 46, a lead screw to be tested 47, a test threaded sleeve 48, a three-jaw chuck 49, and a motor 410.

Since the test threaded sleeve 48 is fitted on the lead screw 47 under test and the test threaded sleeve 48 has a certain thickness, the detection distance of the infrared ranging sensor 57 on the lead screw 47 under test and the detection distance of the test threaded sleeve 48 are different. When the distance changes, it can be seen that the clamping assembly 43 has moved to the same horizontal position as the test threaded sleeve 48.

The electromagnet 5810 is installed on the right end of the fixed block 588, the iron block 5811 is fixed to the left end of the connecting block 587, the spring 5812 is fitted on the outer side of the round rod 589, the outer side of the rotating rod 582 is connected to the movable rod 584 through a guide key, and the movable rod 584 is slidably connected to the rotating rod 582. This setting allows the rotating rod 582 to rotate and drive the movable rod 584 to rotate, and the movable rod 584 can slide along the rotating rod 582. The gear on the outer side of the bevel gear 585 is arc-shaped. The inside of the adjusting rod 52 is provided with a tooth groove, and the tooth groove meshes with the bevel gear 585. This setting allows the bevel gear 585 to rotate and drive the adjusting rod 52 to rotate. The inside of the connecting block 587 is smooth and is slidably connected to the round rod 589. This setting makes it easier for the connecting block 587 to move along the round rod 589.

[0026] The working principle is as follows:

[0027] First, before use, bring the lead screw 47 to be tested to the side of the housing 2 and wait for testing;

[0028] Second, when using it, place the lead screw 47 to be tested on the three-jaw chuck 49 and fix it with the three-jaw chuck 49. Then, put the corresponding test thread sleeve 48 on the lead screw 47 to be tested, start the cylinder 45, and the cylinder 45 drives the mounting sleeve to connect the top of the lead screw 47 to be tested.

[0029] Third, start the electromagnet 5810. The electromagnet 5810 generates a magnetic force that attracts the iron block 5811, causing the iron block 5811 to move toward the electromagnet 5810. When the iron block 5811 moves, it drives the connecting block 587 to move. When the connecting block 587 moves, it drives the movable rod 584 to move through the bearing sleeve 586. At the same time, the connecting block 587 compresses the spring 5812. When the movable rod 584 moves, it drives the bevel gear 585 to move, so that the bevel gear 585 extends into the interior of the adjusting rod 52 and meshes with it.

[0030] Fourth, start motor 583. Motor 583 drives rotating rod 582 to rotate. When rotating rod 582 rotates, it drives moving rod 584 to rotate. When moving rod 584 rotates, it drives bevel gear 585 to rotate. When bevel gear 585 rotates, it drives adjusting rod 52 to rotate. When adjusting rod 52 rotates, it drives sprocket 53 to rotate. When sprocket 53 rotates, it drives chain 54 to move. When chain 54 moves, it drives moving block 55 to move. When moving block 55 moves, it drives clamping assembly 43 to move. When clamping assembly 43 moves, it drives infrared ranging sensor 57 to move. The infrared ranging sensor 57 locates the position of test threaded sleeve 48. When the infrared ranging sensor 57 detects the position of test threaded sleeve 48, the clamping assembly 43 clamps the test threaded sleeve 48.

[0031] Fifth, then turn off the electromagnet 581. After the spring 5812 loses its force, it releases elastic potential energy to push the connecting block 587 to move. When the connecting block 587 moves, it drives the movable rod 584 to move through the bearing sleeve 586. When the movable rod 584 moves, it drives the bevel gear 585 to move. When the bevel gear 585 moves, it disconnects from the adjusting rod 52.

[0032] Sixth, start motor 410. Motor 410 drives the three-jaw chuck 49 to rotate. When the three-jaw chuck 49 rotates, it drives the lead screw 47 to be tested to rotate. When the lead screw 47 to be tested rotates, it drives the test thread sleeve 48 to move. When the test thread sleeve 48 moves, it drives the clamping assembly 43 to move, so that the lead screw 47 to be tested can be tested.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
