Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to a clutch release bearing durability detection device. Background Art

[0002] The clutch release bearing is installed between the clutch and the transmission. Its working principle is to use the return spring to keep the boss of the release bearing on the main release fork at all times, while being able to retreat to the final position, which is about 3-4mm away from the end, ensuring smooth engagement of the clutch. The clutch release bearing is an important part of the car. The clutch pressure plate, release lever and engine crankshaft operate synchronously, so its release fork can only move axially along the clutch output shaft. Installing a clutch release bearing can make the clutch smoother to use, reduce wear and extend the service life of the clutch.

[0003] In order to ensure that the performance of the clutch release bearing can meet the requirements of long-term rotation, it is necessary to perform a durability test on the clutch release bearing. The existing clutch release bearing durability test method is generally to sleeve the clutch release bearing on the motor shaft and rotate it continuously to detect the durability of the clutch release bearing. However, due to the different models and sizes of clutch release bearings, the clutch release bearings detected by the clutch release bearing durability detection device in the prior art are of uniform size, which is not convenient for durability detection of clutch release bearings of different sizes. Therefore, it is necessary to improve the relevant technology. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a clutch release bearing durability detection device.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a clutch release bearing durability detection device, comprising a workbench and a release bearing arranged above the workbench, a support frame is fixed on the workbench, a through groove is penetrated on the support frame, a limiting ring is integrally formed at a position on one side of the through groove, a mounting ring is interference fit in the through groove, the diameter of the mounting ring is larger than the inner diameter of the limiting ring, the inner wall of the mounting ring is interference fit with the outer ring of the release bearing, the inner ring of the release bearing is interference fit with a driven rod, a driving component for driving the driven rod to rotate is arranged on the workbench, the driving component comprises a mounting plate arranged on the top of the workbench and a motor fixed to the side of the mounting plate away from the support frame, the output shaft end of the motor is connected to the driven rod by a coupling, and a fixing component for moving and fixing the mounting plate is arranged on the workbench.

[0006] By adopting the above technical scheme, when the staff uses the clutch release bearing durability detection device to detect the durability of the clutch release bearing, the staff first installs the release bearing to be detected on the driven rod that has an interference fit with the release bearing, and installs the mounting ring that matches the release bearing to be detected into the through groove until the side of the mounting ring close to the motor is tightly against the limit ring, and then installs the release bearing into the mounting ring. Subsequently, the coupling is installed to the end of the driven rod close to the motor, and the fixing assembly is pushed to push the output shaft end of the motor into the coupling. The staff uses an appropriate wrench to lock the coupling. After the output shaft of the motor is fixed to the driven rod, the staff uses a suitable wrench to tighten the first bolt to fix the mounting plate. At this time, the motor is started, and the output shaft end of the motor drives the driven rod to rotate, and the driven rod drives the release bearing to rotate, so that the durability of the release bearing can be tested. When the staff needs to test release bearings of different sizes, they only need to replace the driven rod and mounting ring that match the release bearing to be tested, which improves the applicability of the clutch release bearing durability detection device and changes the traditional method of only being able to test release bearings of the same size.

[0007] Furthermore, the workbench is provided with a T-shaped slide groove connected to the top of the workbench, and the fixing component includes a rectangular block arranged in the T-shaped slide groove and slidingly matched with the T-shaped slide groove, mounting blocks integrally formed on both sides of the mounting plate near the bottom of the mounting plate, and a first bolt penetrating the mounting block and loosely matched with the mounting block, and the lower end of the first bolt penetrates the rectangular block and is threadedly connected to the rectangular block.

[0008] By adopting the above technical solution, after the driven rod is connected to the coupling, the staff loosens the first bolt, and then pushes the mounting block. The first bolt and the rectangular block also move with the movement of the mounting block. When the output shaft end of the motor is pushed into the coupling, the staff uses an appropriate wrench to lock the coupling. After the output shaft of the motor is fixed to the driven rod, the staff uses an appropriate wrench to tighten the first bolt to fix the mounting plate.

[0009] Furthermore, a first plug rod that is gap-matched with the support frame is provided through the top of the support frame, and a plug hole that is plug-matched with the first plug rod is provided at a position on the top of the mounting ring corresponding to the first plug rod.

[0010] By adopting the above technical solution, the staff installs the mounting ring that matches the release bearing to be tested into the through groove until the side of the mounting ring close to the motor is tightly against the limiting ring, and then inserts the first plug rod into the plug-in hole, which has a good limiting effect on the mounting ring and reduces the probability of the mounting ring sliding and affecting the bearing detection results.

[0011] Furthermore, two groups of infrared locators are fixed on one side of the mounting plate close to the support frame and are symmetrically distributed about the output axis of the motor, and the positions of the infrared locators correspond to the positions of the mounting ring.

[0012] By adopting the above technical solution, the infrared locator makes it easy for the staff to observe the flatness of the mounting ring after installation, improves the detection effect of the release bearing detection, and reduces the probability of the release bearing to be detected being tilted due to the tilted installation of the mounting ring.

[0013] Furthermore, a second bolt is threadedly connected to one end of the driven rod away from the mounting plate, a gasket is arranged between the second bolt and the driven rod, and a diameter of the gasket is larger than a diameter of an inner ring of the release bearing.

[0014] By adopting the above technical solution, after the staff installs the release bearing to be tested on the driven rod that has an interference fit with the release bearing, the gasket is placed on the thread of the second bolt, and the second bolt is tightened using a suitable wrench. At this time, the gasket is pressed against the release bearing on one side close to the shift lever. Since the diameter of the gasket is larger than the diameter of the inner ring of the release bearing, the gasket has a good limiting effect on the release bearing, thereby reducing the probability of the release bearing sliding from the driven rod during rotation.

[0015] Furthermore, the workbench is provided with a blocking assembly for blocking the driven rod when opening the coupling, the blocking assembly comprising a first L-shaped plate fixed between the mounting plate and the support frame and away from the support frame, a second L-shaped plate fixed between the mounting plate and the support frame and close to the support frame, and a baffle plate provided between the first L-shaped plate and the second L-shaped plate and slidingly engaged with the first L-shaped plate and the second L-shaped plate, the first L-shaped plate and the second L-shaped plate are each provided with two groups and are symmetrically distributed about the driven rod, and the distance between the side wall of the baffle plate close to the driven rod and the end of the driven rod close to the mounting plate is 0-1mm.

[0016] By adopting the above technical solution, after the staff installs the release bearing to be tested on the driven rod that has an interference fit with the release bearing, when the release bearing needs to be installed in the mounting ring, the baffle is pulled to the position corresponding to the driven rod, and the installation of the release bearing is completed when the end of the driven rod close to the baffle abuts against the baffle. The setting of the baffle has a good limiting effect on the driven rod. Through the cooperation of the first L-shaped plate, the second L-shaped plate and the baffle, the baffle is more stable when subjected to knocking force.

[0017] Furthermore, the tops of the two groups of the first L-shaped plates and the second L-shaped plates away from the baffle are penetrated by a plurality of second plug rods which are gap-matched with the tops of the first L-shaped plates and the second L-shaped plates, and each of the second plug rods is plugged into and matched with the top of the workbench.

[0018] By adopting the above technical solution, the second insertion rod is further improved the connection stability between the first L-shaped plate, the second L-shaped plate and the top of the workbench, and reduces the force applied to the connection between the first L-shaped plate, the second L-shaped plate and the workbench, thereby reducing the probability of the connection becoming loose.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In the present application, the staff first installs the release bearing to be tested on the driven rod that is interference fit with the release bearing, installs the mounting ring that matches the release bearing to be tested into the through groove, and installs the release bearing into the mounting ring. Subsequently, the coupling is installed to the end of the driven rod close to the motor, and the fixing assembly is pushed to push the output shaft end of the motor into the coupling. The staff uses an appropriate wrench to lock the coupling, and the staff uses an appropriate wrench to tighten the first bolt to fix the mounting plate. At this time, the motor is started, and the output shaft end of the motor drives the driven rod to rotate, and the driven rod drives the release bearing to rotate, so that the durability of the release bearing can be tested. When the staff needs to test release bearings of different sizes, they only need to replace the driven rod and the mounting ring that match the release bearing to be tested, thereby improving the applicability of the clutch release bearing durability detection device and changing the traditional method of only being able to detect release bearings of the same size and size.

[0021] 2. In the present application, the infrared locator provided enables the staff to observe the flatness of the mounting ring after installation, thereby improving the detection effect of the release bearing detection and reducing the probability of the release bearing to be detected being tilted due to the tilted installation of the mounting ring.

[0029] The driving assembly 5 is arranged on the workbench 1, and is used to drive the driven rod 21 to rotate. The driving assembly 5 includes a mounting plate 51 and a motor 52. The mounting plate 51 is arranged on the top of the workbench 1. Two groups of infrared locators 511 (the model of the infrared locator 511 is YD-L650P5-10-30) symmetrically distributed about the output axis of the motor 52 are fixed on the side of the mounting plate 51 close to the support frame 3. The position of the infrared locator 511 corresponds to the position of the mounting ring 4. The motor 52 is fixed to the side of the mounting plate 51 away from the support frame 3, and the end of the output shaft of the motor 52 is connected to the driven rod 21 through a coupling 8. The infrared locator 511 is arranged to facilitate the staff to observe the flatness of the mounting ring 4 after installation, improve the detection effect of the release bearing 2, and reduce the probability of the release bearing 2 to be detected being tilted due to the tilted installation of the mounting ring 4.

[0030] The fixing assembly 6 is arranged on the workbench 1, and is used for the installation plate 51 to move and fix. The fixing assembly 6 includes a rectangular block 61, a mounting block 62, and a first bolt 63. The rectangular block 61 is arranged in the T-shaped slide groove 11 and is slidably matched with the T-shaped slide groove 11. The mounting block 62 is integrally formed on the side wall of the installation plate 51 near the bottom of the installation plate 51.

At this time, the gasket 2111 is pressed against the release bearing 2 on the side close to the slave lever, which reduces the probability of the release bearing 2 sliding off the driven rod 21 during the rotation process.

[0032] In order to effectively limit the driven rod 21, a blocking assembly 7 is provided on the workbench 1 for blocking the driven rod 21 when the coupling 8 is opened. The blocking assembly 7 includes a first L-shaped plate 71, a second L-shaped plate 72 and a baffle 73. The first L-shaped plate 71 is fixed between the mounting plate 51 and the support frame 3 and at a position away from the support frame 3. The second L-shaped plate 72 is fixed between the mounting plate 51 and the support frame 3 and at a position close to the support frame 3. Two groups of the first L-shaped plate 71 and the second L-shaped plate 72 are provided and are symmetrically distributed about the driven rod 21. The baffle 73 is provided between the first L-shaped plate 71 and the second L-shaped plate 72 and is slidably matched with the first L-shaped plate 71 and the second L-shaped plate 72. The distance between the side wall of the baffle 73 close to the driven rod 21 and the end of the driven rod 21 close to the mounting plate 51 is 0-1 mm. After the staff installs the release bearing 2 to be tested on the driven rod 21 that is interference fit with the release bearing 2, when the release bearing 2 needs to be installed in the mounting ring 4, pull the baffle 73 to the position corresponding to the driven rod 21, and when the end of the driven rod 21 close to the baffle 73 abuts against the baffle 73, the installation of the release bearing 2 can be completed. Through the cooperation of the first L-shaped plate 71, the second L-shaped plate 72 and the baffle 73, the baffle 73 is more stable when subjected to the force of knocking.

[0033] In this embodiment, the tops of the two groups of first L-shaped plates 71 and second L-shaped plates 72 away from the baffle 73 are penetrated by a plurality of second plug rods 711 that are gap-matched with the tops of the first L-shaped plates 71 and second L-shaped plates 72, and each second plug rod 711 is plugged and matched with the top of the workbench 1. The second plug rods 711 further improve the connection stability of the first L-shaped plates 71, the second L-shaped plates 72 and the top of the workbench 1, and reduce the force of the connection between the first L-shaped plates 71, the second L-shaped plates 72 and the workbench 1, thereby reducing the probability of the connection being loosened due to the force of being struck.

[0034] The use principle of a clutch release bearing 2 durability detection device in the present embodiment is as follows: when the staff uses the clutch release bearing 2 durability detection device to detect the durability of the clutch release bearing 2, the staff first installs the release bearing 2 to be detected on the driven rod 21 that is interference fit with the release bearing 2, and installs the mounting ring 4 that matches the release bearing 2 to be detected into the through groove 31, until the side of the mounting ring 4 close to the motor 52 is tightly against the limit ring 32, and then installs the release bearing 2 into the mounting ring 4, and then installs the coupling 8 to the end of the driven rod 21 close to the motor 52. The staff loosens the first bolt 63, and then pushes the mounting block 62. The first bolt 63 and the rectangular block 61 also move with the movement of the mounting block 62. When the output of the motor 52 After the shaft end is pushed into the coupling 8, the staff uses an appropriate wrench to lock the coupling 8. After the output shaft of the motor 52 is fixed to the driven rod 21, the staff uses an appropriate wrench to tighten the first bolt 63 to fix the mounting plate 51. At this time, the motor 52 is started, and the output shaft end of the motor 52 drives the driven rod 21 to rotate, and the driven rod 21 drives the release bearing 2 to rotate, so that the durability of the release bearing 2 can be tested. When the staff needs to test release bearings 2 of different sizes, they only need to replace the driven rod 21 and the mounting ring 4 that match the release bearing 2 to be tested, thereby improving the applicability of the durability detection device for the clutch release bearing 2 and changing the traditional method of only being able to test release bearings 2 of the same size.
