Description

Technical Field

[0001] This utility model relates to the field of bearing testing technology, specifically a self-aligning roller bearing testing device. Background Technology

[0002] Self-aligning roller bearings have two rows of rollers and mainly bear radial loads, but can also bear axial loads in any direction. They have high radial load capacity and are particularly suitable for heavy loads or vibration loads. However, they cannot bear pure axial loads. After the bearing is manufactured, it is necessary to test its strength, including testing its rotational load-bearing capacity.

[0003] For example, application number CN202322317909.7 discloses a self-aligning roller bearing testing device, belonging to the field of bearing testing technology. It includes a mounting base plate on which a self-aligning roller bearing is mounted; a testing mechanism disposed on the front side of the mounting base plate, used for rotating the self-aligning roller bearing; and a limiting mechanism disposed on the mounting base plate, used for limiting the self-aligning roller bearings of different specifications. This utility model includes a testing mechanism, enabling the detection of the self-aligning roller bearing's rotational load-bearing capacity. Furthermore, it adjusts the pressure exerted by the testing mechanism on the self-aligning roller bearing, allowing the device to test not only the rotational speed but also the load-bearing capacity of the self-aligning roller bearing, increasing the versatility of the device's testing functions. The limiting mechanism also allows for limiting and testing of self-aligning roller bearings of different specifications.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem that the inner ring of a self-aligning roller bearing can rotate at a certain angle, making general bearing testing devices unsuitable for self-aligning roller bearings and potentially causing inaccurate measurements during testing due to fluctuations in the inner ring, the use of self-aligning roller bearings is problematic. Since the models and sizes of self-aligning roller bearings vary, and their widths differ, the first mounting plate is fixed to the top of the mounting base plate, resulting in an unadjustable distance between the sliding block and the fixed plate. Therefore, for some self-aligning roller bearings with larger widths, they cannot be placed in the testing device. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a self-aligning roller bearing testing device. This device addresses the issue that, due to the varying models and sizes of self-aligning roller bearings, their widths differ. Since the first mounting plate is fixed to the top of the mounting base plate, the distance between the sliding block and the fixed plate is not adjustable. This makes it impossible to fit certain wider self-aligning roller bearings into the testing device, thus solving the problem of adjusting the bearing clamping distance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-aligning roller bearing testing device, comprising a mounting base plate, a first screw, a second screw, a first mounting plate, a second mounting plate, a sliding block, a fixed plate, a conveying device, and a fixed spike. The fixed plate is fixedly connected to the right side of the top of the mounting base plate, the conveying device is fixedly connected to the right side of the inner cavity of the mounting base plate, the sliding block is disposed on the top of the mounting base plate, the first screw is movably connected to the front side of the top of the mounting base plate and penetrates the bottom of the sliding block, the first screw is threadedly connected to the sliding block, and the first mounting plate is movably connected to the rear side of the top of the mounting base plate and penetrates the bottom of the sliding block, the first mounting plate is slidably connected to the sliding block. The second mounting plate is fixedly connected to the top of the first mounting plate. The top of the first screw extends through to the front side of the top of the second mounting plate. The second screw is threadedly connected to the left side of the sliding block, and the right end of the second screw extends through the right side of the sliding block. The fixing spike is fixedly connected to the right end of the second screw. The top of the mounting base plate has first sliding grooves on both sides. The bottom end of the first screw and the bottom end of the first mounting plate are both provided with first sliders. The bottom end of the first screw is movably connected to the front first slider. The bottom of the first mounting plate is fixedly connected to the rear first slider. The first slider is slidably connected to the second sliding groove. The top of the mounting base plate has positioning mechanisms on both sides.

[0007] In a preferred embodiment of this utility model, the positioning mechanism includes a baffle, a spring, a U-shaped plate, and a positioning block. The baffles are all fixedly connected to both sides of the top of the mounting base plate, the U-shaped plates are all fixedly connected to the top of the inner side of the first slider, the spring is fixedly connected to the top of the inner side of the first slider, and the positioning block is fixedly connected to the other end of the first tension spring. The inner side of the positioning block is movably connected to the outer side of the baffle.

[0008] As a preferred embodiment of this utility model, a second sliding groove is provided at the bottom of the inner side of the U-shaped plate, and a second slider is fixedly connected to the bottom of the positioning block, with the second slider slidably connected to the second sliding groove.

[0009] As a preferred embodiment of this utility model, grooves are provided on both sides of the U-shaped plate, and pull rods are fixedly connected to both sides of the positioning block, with the pull rods slidably connected to the grooves.

[0010] As a preferred embodiment of this utility model, a third sliding groove is provided on both sides of the U-shaped plate, and a third slider is slidably connected inside the third sliding groove. The outer side of the third slider is movably connected to the inside of the spring.

[0011] As a preferred embodiment of this utility model, a telescopic rod is fixedly connected to the top of the inner side of the first slider, the other end of the telescopic rod is fixedly connected to the outer side of the positioning block, and the spring is sleeved on the surface of the telescopic rod.

[0012] As a preferred embodiment of this utility model, the inner side of the positioning block is provided with anti-slip grooves, and the anti-slip grooves are provided in a plurality of them and are distributed in a rectangular and equidistant manner.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a first sliding groove and a first sliding block, moves the sliding block through a first mounting plate and a first screw. Then, the first sliding block moves the first mounting plate and the first screw inside the first sliding groove, thereby completing the adjustment of the sliding block. This solves the problem that due to the different models and sizes of self-aligning roller bearings, their widths are not the same. The first mounting plate is fixed to the top of the mounting base plate, which makes the distance between the sliding block and the fixed plate non-adjustable. Therefore, for some self-aligning roller bearings with larger widths, they cannot be placed in the detection device. This invention has the advantage of adjusting the bearing clamping distance.

[0015] 2. This utility model, by setting a positioning mechanism, when adjusting the distance between the sliding block and the fixed plate, moves the positioning block inside the U-shaped plate, causing the positioning block to disengage from the contact friction with the baffle. Simultaneously, the positioning block drives the spring to move and compress, then the sliding block drives the first screw and the first mounting plate to move. Afterward, the first mounting plate and the first screw drive the two sets of first sliders to move inside the first slide groove. Finally, after adjustment, the spring releases pressure, causing the positioning block to move inside the U-shaped plate and contact the outside of the baffle for friction, thereby completing the positioning of the first slider after movement. Furthermore, by setting a second slide groove and a second slider, when the positioning block drives the spring to move, the positioning block simultaneously drives the second slider to move, causing the second slider to move inside the second groove, thereby completing the limitation of the movement of the positioning block.

[0016] 3. This utility model, by setting a groove and a pull rod, allows the positioning block to move within the groove when the positioning block moves. This facilitates the movement of the spring within the U-shaped plate. Furthermore, by setting a third sliding groove and a third slider, when the pull rod moves within the groove through the positioning block and the spring, the third slider moves upward through the second sliding groove. When the pull rod passes through the third sliding groove, the third slider moves to the bottom of the third sliding groove, blocking the pull rod and thus positioning the spring.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3As shown, this utility model provides a self-aligning roller bearing testing device, including a mounting base plate 1, a first screw 2, a second screw 3, a first mounting plate 4, a second mounting plate 5, a sliding block 6, a fixed plate 7, a conveying device 8, and a fixed spike 9. The fixed plate 7 is fixedly connected to the right side of the top of the mounting base plate 1, the conveying device 8 is fixedly connected to the right side of the inner cavity of the mounting base plate 1, the sliding block 6 is disposed on the top of the mounting base plate 1, the first screw 2 is movably connected to the front side of the top of the mounting base plate 1 and passes through the bottom of the sliding block 6, the first screw 2 is threadedly connected to the sliding block 6, the first mounting plate 4 is movably connected to the rear side of the top of the mounting base plate 1 and passes through the bottom of the sliding block 6, the first mounting plate 4 is slidably connected to the sliding block 6, and the second screw 3 is threadedly connected to the sliding block 6. The first mounting plate 4 is movably connected to the rear side of the top of the mounting base plate 1 and passes through the bottom of the sliding block 6, the first mounting plate 4 is slidably connected to the sliding block 6, and the second screw 3 is threadedly connected to the sliding block 6. Mounting plate 5 is fixedly connected to the top of first mounting plate 4. The top of first screw 2 extends through to the front side of the top of second mounting plate 5. Second screw 3 is threadedly connected to the left side of sliding block 6. The right end of second screw 3 extends through the right side of sliding block 6. Fixed spike 9 is fixedly connected to the right end of second screw 3. First sliding grooves 10 are provided on both sides of the top of mounting base plate 1. First sliders 11 are provided at the bottom of first screw 2 and the bottom of first mounting plate 4. The bottom of first screw 2 is movably connected to the front first slider 11. The bottom of first mounting plate 4 is fixedly connected to the rear first slider 11. First slider 11 is slidably connected to second sliding groove 13. Positioning mechanisms 12 are provided on both sides of the top of mounting base plate 1.

[0023] refer to Figure 2 The positioning mechanism 12 includes a baffle 121, a spring 122, a U-shaped plate 123, and a positioning block 124. The baffle 121 is fixedly connected to both sides of the top of the mounting base plate 1. The U-shaped plate 123 is fixedly connected to the top of the inner side of the first slider 11. The spring 122 is fixedly connected to the top of the inner side of the first slider 11. The positioning block 124 is fixedly connected to the other end of the first tension spring. The inner side of the positioning block 124 is movably connected to the outer side of the baffle 121.

[0024] As a technical optimization of this utility model, by setting a positioning mechanism 12, when adjusting the distance between the sliding block 6 and the fixed plate 7, the positioning block 124 moves inside the U-shaped plate 123, causing the positioning block 124 to disengage from the contact friction with the baffle 121. At the same time, the positioning block 124 drives the spring 122 to move and squeeze, and then the sliding block 6 drives the first screw 2 and the first mounting plate 4 to move. After that, the first mounting plate 4 and the first screw 2 drive the two sets of first sliders 11 to move inside the first slide groove 10. Finally, after adjustment, the spring 122 releases pressure and drives the positioning block 124 to move inside the U-shaped plate 123 and contact the outside of the baffle 121, thereby completing the positioning of the first slider 11 after movement.

[0025] refer to Figure 3The bottom of the inner side of the U-shaped plate 123 is provided with a second sliding groove 13, and the bottom of the positioning block 124 is fixedly connected with a second slider 14, which is slidably connected to the second sliding groove 13.

[0026] As a technical optimization of this utility model, by setting a second sliding groove 13 and a second slider 14, when the positioning block 124 drives the spring 122 to move, the positioning block 124 simultaneously drives the second slider 14 to move, so that the second slider 14 moves inside the second groove 15, thereby completing the limitation of the movement of the positioning block 124.

[0027] refer to Figure 2 The U-shaped plate 123 has grooves 15 on both sides, and the positioning block 124 has a pull rod 16 fixedly connected to both sides, with the pull rod 16 slidably connected to the groove 15.

[0028] As a technical optimization of this utility model, by setting the groove 15 and the pull rod 16, when the positioning block 124 moves, the pull rod 16 is moved to drive the positioning block 124 to move inside the groove 15, thereby facilitating the positioning block 124 to drive the spring 122 to move inside the U-shaped plate 123.

[0029] refer to Figure 3 The U-shaped plate 123 has a third slide groove 17 on both sides. The third slide groove 17 is slidably connected to the inside of the third slide groove 17. The outside of the third slide groove 18 is movably connected to the inside of the spring 122.

[0030] As a technical optimization of this utility model, by setting a third slide groove 17 and a third slider 18, when the rod inside the groove 15 of the pull rod 16 is squeezed and moved by the positioning block 124, the third slider 18 inside the second slide groove 13 moves upward. Then, when the pull rod 16 passes the third slide groove 17, the third slider 18 moves to the bottom inside the third slide groove 17, so that the third slider 18 blocks the pull rod 16, thereby completing the positioning of the spring 122.

[0031] refer to Figure 2 A telescopic rod 19 is fixedly connected to the top of the inner side of the first slider 11, and the other end of the telescopic rod 19 is fixedly connected to the outer side of the positioning block 124. A spring 122 is sleeved on the surface of the telescopic rod 19.

[0032] As a technical optimization of this utility model, by setting the telescopic rod 19, the safety and stability of the spring 122 are increased, and the spring 122 is prevented from twisting and being damaged during the compression process, thereby extending the service life of the spring 122.

[0033] refer to Figure 3The inner side of the positioning block 124 is provided with anti-slip grooves 20, and there are several anti-slip grooves 20 distributed in a rectangular and equidistant manner.

[0034] As a technical optimization of this utility model, by setting the anti-slip groove 20, the friction generated by the contact between the positioning block 124 and the baffle 121 is increased, thereby strengthening the friction of the positioning block 124 and making the positioning of the positioning block 124 more secure.

[0035] The working principle and usage process of this utility model are as follows: When adjusting the distance between the sliding block 6 and the fixed plate 7, the pull rod 16 is moved inside the groove 15, causing the pull rod 16 to move the positioning block 124 inside the U-shaped plate 123. This causes the positioning block 124 to disengage from the contact friction with the baffle 121. At the same time, the positioning block 124 causes the spring 122 to move and compress. When the pull rod 16 passes the third slide groove 17, the third slider 18 moves from the top of the third slide groove 17 to the bottom inside the third slide groove 17, blocking the pull rod 16 and thus positioning the spring 122. After that, the first mounting plate 4 and the first screw 2 are moved together. The two sets of first sliders 11 move inside the first slide groove 10. After final adjustment, the third slider 18 moves inside the third slide groove 17 to disengage from the pull rod 16, causing the spring 122 to release pressure and drive the positioning block 124 to move inside the U-shaped plate 123 and rub against the outside of the baffle 121, thereby completing the positioning of the first slider 11 after movement. This achieves the advantage of adjusting the bearing clamping distance. At the same time, while the positioning block 124 drives the spring 122 to move, the positioning block 124 also drives the second slider 14 to move inside the second groove 15, thereby limiting the movement of the positioning block 124.

[0036] In summary, this adjustable-angle spray device, through the setting of a first sliding groove 10 and a first slider 11, uses a first mounting plate 4 and a first screw 2 to drive the sliding block 6 to move. Then, the first slider 11 drives the first mounting plate 4 and the first screw 2 to move inside the first sliding groove 10, thereby completing the movement adjustment of the sliding block 6. This solves the problem that due to the different models and sizes of self-aligning roller bearings, their widths are not the same. The first mounting plate is fixed to the top of the mounting base plate, resulting in the distance between the sliding block and the fixed plate being non-adjustable. Therefore, for some self-aligning roller bearings with larger widths, they cannot be placed in the testing device.
