Description

Technical Field

[0001] The present invention relates to the technical field of linear guide performance testing, and in particular to a linear guide performance testing device and a testing method. Background Art

[0002] A linear guide is a component that enables a slider to perform linear motion. The slider can only perform linear motion on the linear guide. After production, the linear guide needs to be tested for performance. The most basic test includes the surface flatness of the linear guide and the running smoothness of the slider on the guide. Some testing devices set a distance measuring device on a line on both sides of the linear guide to measure whether the distance between each point on the linear guide and the distance measuring device is equal, thereby determining the flatness of the linear guide.

[0003] The defects of the existing linear guide performance testing device are:

[0004] 1. Patent document US07210242B2 discloses a method for detecting the verticality of a lifting guide rail and a detector for implementing the method. The guide rail detection device in the patent can detect the verticality of the guide rail, but cannot detect whether there are protrusions on the guide rail. The protrusions on the guide rail are likely to affect the stability of the operation of the slider. Therefore, a linear guide rail performance testing device that can detect whether there are protrusions on the guide rail is needed to solve this problem.

[0005] 2. Patent document JPH0551184A discloses an elevator guide rail detection device. The guide rail detection device in the patent detects the deformation of the guide rail by receiving a pulse signal, but cannot detect the bearing capacity of the guide rail under the condition of bending force. Some guide rails will be affected by the force perpendicular to the guide rail during operation. Therefore, a linear guide rail performance testing device capable of measuring the bearing capacity of the guide rail to bending force is needed to solve this problem.

[0006] 3. Patent document US20160102962A1 discloses a guide rail direct-beam tester. The guide rail detection device in the patent can determine the straightness of the guide rail, but the device cannot grind the protrusions on the guide rail to make the protrusions flat. Therefore, a linear guide rail performance testing device that can grind the protrusions on the guide rail is needed to solve this problem.

[0007] 4. Patent document CN206161290U discloses a rolling linear guide performance test device. The guide test device in the patent can perform temperature rise measurement, noise measurement, vibration measurement, and acceleration measurement on the guide. However, after the guide test is completed, the staff needs to manually remove the guide, which affects the staff's inspection efficiency of the guide. Therefore, a linear guide performance test device that can easily remove the guide from the inspection device is needed to solve this problem. Summary of the invention

[0018] Preferably, the testing method of the linear guide performance testing device is as follows:

[0019] S1. Place the linear guide between the first clamping plates on the first mounting plate, and install the slider matching the linear guide on the linear guide. Then, the first hydraulic cylinder drives the first clamping plate to fix the linear guide. Then, the ninth hydraulic cylinder drives the first lifting frame to move downward, so that the pressing plate presses the slider on the linear guide. Then, the second hydraulic cylinder drives the third clamping plate to move inward, so that the third clamping plate clamps the slider on the linear guide.

[0020] S2, the first motor drives the first movable plate to move forward and backward, so that the slider inside the third clamping plate moves forward and backward on the linear guide rail. When a protruding part appears on the top of the linear guide rail, the slider on the linear guide rail will be pushed up, thereby applying an upward force to the pressure plate, thereby causing the pressure of the first pressure sensor to increase. When protruding parts appear on both sides of the linear guide rail, or the linear guide rail is curved, the second pressure sensor will also experience a drastic change in pressure when the slider moves to the corresponding part of the linear guide rail.

[0021] S3. When it is necessary to measure the bending force that the linear guide rail can withstand, the first lifting plate is driven downward by the third hydraulic cylinder, and then the fourth hydraulic cylinder drives the pressing frame to squeeze the linear guide rail. The third pressure sensor measures the pressure of the pressing frame on the linear guide rail and transmits the pressure value to the controller, thereby judging the ability of the linear guide rail to withstand the bending force.

[0022] S4. When there is a raised part on the linear guide rail, the first motor can drive the grinding head to move forward and backward so that the grinding head moves to the raised part of the linear guide rail, and then the fifth hydraulic cylinder drives the grinding head to move left and right so that the grinding head moves in the left and right directions to the place where the linear guide rail needs to be polished, and then the sixth hydraulic cylinder drives the grinding head to move down to contact the raised part of the linear guide rail, and then the second motor drives the grinding head to rotate, thereby polishing the raised part of the linear guide rail;

[0023] S5. After grinding is completed, if the stripping assembly is the seventh hydraulic cylinder, the moving rod and the fourth clamping plate, the seventh hydraulic cylinder drives the fourth clamping plate to move backward to both sides of the linear guide rail, and then the eighth hydraulic cylinder drives the fourth clamping plate to squeeze the linear guide rail, and then the first hydraulic cylinder drives the first clamping plate to move to both sides, thereby releasing the fixation of the linear guide rail, and then the seventh hydraulic cylinder drives the fourth clamping plate to move forward, thereby driving the linear guide rail to move forward, so that the linear guide rail falls from the front of the first mounting plate, realizing the blanking of the linear guide rail, and the staff can install a new linear guide rail above the first mounting plate during the process of removing the linear guide rail, thereby speeding up the test.

[0024] Preferably, the step S5 further includes the following steps:

[0025] S51. If the stripping assembly is a mounting block, a rotating plate and a vibrator, the second piston rod is driven upward by the cylinder, and the second piston rod pushes the rotating plate upward to rotate the rotating plate upward. Then the vibrator vibrates, thereby driving the rotating plate to vibrate, so that the linear guide rail slides off the rotating plate. At the same time, impurities on the rotating plate can also be vibrated and slide off. When passing through the grid holes on the rotating plate, the impurities will pass through the grid holes and enter the collection box from the opening, which is convenient for handling the impurities.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention enables the pressure plate to press the slider on the linear guide rail, and enables the third clamping plate to clamp the slider on the linear guide rail. The first motor drives the first movable plate to move forward and backward, so that the slider inside the third clamping plate moves forward and backward on the linear guide rail. When a protruding part appears on the top or both sides of the linear guide rail, the slider pressure plate and the third clamping plate will apply pressure, and then apply pressure to the first pressure sensor and the second pressure sensor respectively, so as to facilitate the detection of the flatness of the top and both sides of the linear guide rail and whether it is bent, so that the linear guide rail performance testing device can apply pressure to the first pressure sensor and the second pressure sensor respectively through the slider, so as to facilitate the detection of the flatness of the top and both sides of the linear guide rail and whether it is bent.

[0028] 2. When it is necessary to measure the bending force that the linear guide can withstand, the present invention drives the first lifting plate downward through the third hydraulic cylinder, and then drives the pressure frame to squeeze the linear guide through the fourth hydraulic cylinder. The third pressure sensor measures the pressure of the pressure frame on the linear guide, and transmits the pressure value to the controller, thereby judging the ability of the linear guide to withstand the bending force. The linear guide performance testing device drives the first lifting plate downward through the third hydraulic cylinder, and then drives the pressure frame to squeeze the linear guide through the fourth hydraulic cylinder. The third pressure sensor measures the pressure of the pressure frame on the linear guide, and transmits the pressure value to the controller, thereby judging the ability of the linear guide to withstand the bending force.

[0029] 3. In the present invention, when there is a raised part on the linear guide rail, the first motor can drive the grinding head to move forward and backward so that the grinding head moves to the raised part of the linear guide rail, and then the fifth hydraulic cylinder drives the grinding head to move left and right so that the grinding head moves in the left and right directions to the place where the linear guide rail needs to be polished, and then the sixth hydraulic cylinder drives the grinding head to move downward to contact the raised part of the linear guide rail, and then the second motor drives the grinding head to rotate, and then the raised part of the linear guide rail is polished. After the polishing is completed, the linear guide rail performance testing device can use the grinding head to polish the raised parts on the top and both sides of the linear guide rail and grind them flat.

[0030] 4. The present invention can realize the blanking of the linear guide through the stripping assembly, and the staff can install a new linear guide above the first mounting plate while the linear guide is being removed, thereby speeding up the test speed and enabling the linear guide performance testing device to realize the blanking of the linear guide through the stripping assembly, and the staff can install a new linear guide above the first mounting plate while the linear guide is being removed, thereby speeding up the test speed.

[0059] S1, place the linear guide between the first clamping plates 4 on the first mounting plate 1, and install the slider matching the linear guide on the linear guide, then the first hydraulic cylinder 3 drives the first clamping plate 4 to fix the linear guide, then the ninth hydraulic cylinder 49 drives the first lifting frame 11 to move downward, so that the pressing plate 13 presses the slider on the linear guide, and then the second hydraulic cylinder 14 drives the third clamping plate 18 to move inward, so that the third clamping plate 18 clamps the slider on the linear guide;

[0060] S2, the first motor 6 drives the first movable plate 8 to move forward and backward, so that the slider inside the third clamping plate 18 moves forward and backward on the linear guide rail. When a protruding part appears on the top of the linear guide rail, the slider on the linear guide rail will be pushed up, thereby applying an upward force to the pressure plate 13, thereby increasing the pressure of the first pressure sensor 12. When protruding parts appear on both sides of the linear guide rail, or the linear guide rail is curved, the second pressure sensor 16 will also experience a drastic change in pressure when the slider moves to the corresponding part of the linear guide rail.

[0061] S3. When it is necessary to measure the bending force that the linear guide rail can withstand, the first lifting plate 21 is driven downward by the third hydraulic cylinder 20, and then the fourth hydraulic cylinder 22 drives the pressing frame 25 to press the linear guide rail, and the third pressure sensor 24 measures the pressure of the pressing frame 25 on the linear guide rail, and transmits the pressure value to the controller 48, thereby determining the ability of the linear guide rail to withstand the bending force;

[0062] S4. When there is a raised part on the linear guide rail, the first motor 6 can drive the grinding head 32 to move forward and backward so that the grinding head 32 moves to the raised part of the linear guide rail, and then the fifth hydraulic cylinder 27 drives the grinding head 32 to move left and right so that the grinding head 32 moves in the left and right directions to the place where the linear guide rail needs to be polished, and then the sixth hydraulic cylinder 29 drives the grinding head 32 to move down and contact the raised part of the linear guide rail, and then the second motor 31 drives the grinding head 32 to rotate, thereby grinding the raised part of the linear guide rail;

[0063] S5. After grinding is completed, if the stripping assembly is the seventh hydraulic cylinder 33, the moving rod 34 and the fourth clamping plate 37, the seventh hydraulic cylinder 33 drives the fourth clamping plate 37 to move backward to both sides of the linear guide rail, and then the eighth hydraulic cylinder 36 drives the fourth clamping plate 37 to squeeze the linear guide rail, and then the first hydraulic cylinder 3 drives the first clamping plate 4 to move to both sides, thereby releasing the fixation of the linear guide rail, and then the seventh hydraulic cylinder 33 drives the fourth clamping plate 37 to move forward, thereby driving the linear guide rail to move forward, so that the linear guide rail falls from the front of the first mounting plate 1, realizing the blanking of the linear guide rail, and the staff can install a new linear guide rail above the first mounting plate 1 during the process of removing the linear guide rail, thereby speeding up the testing speed.

[0064] S5 also includes the following steps:

[0065] S51. If the stripping assembly is a mounting block 38, a rotating plate 39 and a vibrator 41, the second piston rod 46 is driven to move upward by the cylinder 45, and the second piston rod 46 pushes the rotating plate 39 upward to rotate the rotating plate 39 upward, and then the vibrator 41 vibrates, thereby driving the rotating plate 39 to vibrate, so that the linear guide rail slides off the rotating plate 39, and at the same time, impurities on the rotating plate 39 can also be vibrated and slide off, and the impurities will pass through the grid holes 40 on the rotating plate 39 when passing through the grid holes 40, and enter the inside of the collection box 44 from the opening 42, so that the impurities can be easily processed.

[0066] Working principle: Before using the linear guide performance test device, you should first check whether there are any problems that affect the use of the linear guide performance test device. First, place the linear guide between the first clamping plate 4 on the first mounting plate 1, and install the slider matching the linear guide on the linear guide. Then the first hydraulic cylinder 3 drives the first clamping plate 4 to fix the linear guide. Then the ninth hydraulic cylinder 49 drives the first lifting frame 11 to move downward, so that the pressure plate 13 presses the slider on the linear guide. Then the second hydraulic cylinder 14 drives the third clamping plate 18 to move inward, so that the third clamping plate 18 clamps the slider on the linear guide. The first motor 6 drives the first movable plate 8 to move back and forth, so that the slider inside the third clamping plate 18 moves back and forth on the linear guide. When the linear guide When a protruding portion appears on the top, the slider on the linear guide rail will be pushed up, thereby applying an upward force to the pressure plate 13, which in turn causes the pressure of the first pressure sensor 12 to increase. When protruding portions appear on both sides of the linear guide rail, or the linear guide rail is curved, the second pressure sensor 16 will also experience a drastic change in pressure when the slider moves to the corresponding portion of the linear guide rail. When it is necessary to measure the bending force that the linear guide rail can withstand, the first lifting plate 21 is driven downward by the third hydraulic cylinder 20, and then the fourth hydraulic cylinder 22 drives the pressure frame 25 to squeeze the linear guide rail. The third pressure sensor 24 measures the pressure of the pressure frame 25 on the linear guide rail, and transmits the pressure value to the controller 48, thereby determining whether the linear guide rail is bent. In order to improve the ability of the linear guide to withstand bending force, when there is a raised part on the linear guide, the first motor 6 can be used to drive the grinding head 32 to move forward and backward so that the grinding head 32 moves to the raised part of the linear guide, and then the fifth hydraulic cylinder 27 drives the grinding head 32 to move left and right so that the grinding head 32 moves in the left and right directions to the place where the linear guide needs to be polished, and then the sixth hydraulic cylinder 29 drives the grinding head 32 to move down and contact the raised part of the linear guide, and then the second motor 31 drives the grinding head 32 to rotate, and then the raised part of the linear guide is polished. After the polishing is completed, if the stripping assembly is the seventh hydraulic cylinder 33, the moving rod 34 and the fourth clamping plate 37, the seventh hydraulic cylinder 33 drives the fourth clamping plate 37 to move backward to both sides of the linear guide, and then the eighth hydraulic cylinder 3 6 drives the fourth clamping plate 37 to squeeze the linear guide rail, then the first hydraulic cylinder 3 drives the first clamping plate 4 to move to both sides, thereby releasing the fixation of the linear guide rail, and then the seventh hydraulic cylinder 33 drives the fourth clamping plate 37 to move forward, thereby driving the linear guide rail to move forward, so that the linear guide rail falls from the front of the first mounting plate 1, and the linear guide rail is dropped. The staff can install a new linear guide rail above the first mounting plate 1 during the process of the linear guide rail being removed, thereby speeding up the test speed. If the stripping assembly is a mounting block 38, a rotating plate 39 and a vibrator 41, the second piston rod 46 is driven to move upward by the cylinder 45, and the second piston rod 46 pushes the rotating plate 39 upward, so that the rotating plate 39 rotates upward, and then the vibrator 41 vibrates,This causes the rotating plate 39 to vibrate, so that the linear guide rail slides off the rotating plate 39, and at the same time, impurities on the rotating plate 39 can also be vibrated and slide off. When the impurities pass through the mesh holes 40 on the rotating plate 39, they will pass through the mesh holes 40 and enter the collection box 44 from the opening 42, making it easy to handle the impurities.
