Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a quick fixing fixture for bearings. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings generally include inner ring bearings and outer ring bearings, with balls between the inner and outer rings. Such bearings often require drilling operations and rotation accuracy detection during processing, which all require the bearings to be fixed. Therefore, bearing fixtures have become the basic equipment for bearing processing. Traditional bearing fixtures have a single function and can only act on bearings of one specification. The operating platform needs to be changed according to the different bearing specifications, which increases the production cost of the enterprise.

[0003] For example, the patent publication number CN201820683918.4 discloses a bearing fixture that has two functions for precision detection and fixed drilling of bearings of different models. It has multiple functions and reasonable design. It uses the upper base to isolate noise, the shock-absorbing pad, the buffer pad and the spring to achieve triple shock absorption, and the suction cup fixes the fixture, which enhances the stability of the fixture and effectively extends the service life of the equipment. However, this technical solution still has shortcomings, as follows:

[0004] The surface temperature of the bearing is often too high after processing, making the material removal process more difficult. In particular, the device also uses an inner and outer double fixing structure, which makes disassembly more difficult. Secondly, during use, the inner layer structure is easily offset when it is limited to the outside, affecting the fixing efficiency. To this end, we propose a quick fixing fixture for bearings to solve the above-mentioned problems. Utility Model Content

[0040] The following is combined with Figure 1-5 The utility model is described in further detail.

[0041] Embodiment 1, refer to Figure 1-3 In order to solve the problem that the existing bearings are easily offset during the limiting process, the utility model discloses a quick fixing fixture for the bearings.

[0042] The device assembly 100 includes a device body 101, a support block 102 is arranged at the center of the device body 101, and an external limiting mechanism 103 is arranged around the device body 101;

[0043] The inner limit assembly 200 also includes a first cylinder 201, which is located above the support block 102. The first cylinder 201 is connected with a piston rod 202 on all sides, and the outer side of the piston rod 202 is connected with a linkage block 203. The linkage block 203 is driven to move by the cooperation of the first cylinder 201 and the piston rod 202, so as to facilitate subsequent clamping work. The interior of the linkage block 203 is connected with a reset spring 204, and the outer side of the reset spring 204 is connected with an anti-slip block 205. The bearing is pre-limited by the anti-slip block 205 to avoid bearing deviation. The outer side of the anti-slip block 205 is connected with a first clamping plate 206, and the center of the linkage block 203 is connected with a second clamping plate 207.

[0044] The connection between the device body 101 and the support block 102 is a rotational connection. Three groups of external limit mechanisms 103 are evenly and equidistantly distributed around the device body 101. The external limit mechanism 103 is composed of a cylinder, a fixed block and a clamping block. The external limit mechanism 103 is used to limit the outer side of the bearing to ensure that the bearing will not shake during processing.

[0045] The connection between the first cylinder 201 and the piston rod 202 is a piston connection. The piston rod 202 and the linkage block 203 are installed in an integrated manner. The center of the linkage block 203 coincides with the center of the second clamping plate 207. The first cylinder 201 cooperates with the piston rod 202 to drive the linkage block 203 and the second clamping plate 207 to be limited and fixed, thereby ensuring the bearing positioning work.

[0046] The linkage block 203 forms a spring buffer structure with the anti-slip block 205 through the return spring 204. The anti-slip block 205 and the first clamping plate 206 are installed in an integrated manner. An annular limiting structure is arranged on the outer side of the return spring 204. The linkage block 203 cooperates with the return spring 204 so that the anti-slip block 205 and the first clamping plate 206 can pre-contact the bearing, preliminarily limit the bearing, and avoid bearing deviation.

[0047] The specific working principle is: first, when the bearing needs to be processed, the bearing to be processed is placed above the device body 101, and then the switch of the first cylinder 201 is turned on, so that the first cylinder 201 drives the piston rod 202 to move, and then the piston rod 202 drives the linkage block 203 to move toward the outside, so that the linkage block 203 drives the return spring 204 to move, and then the return spring 204 drives the anti-dropping block 205 to move toward the position of the bearing until the first clamping plate 206 contacts the bearing. Due to the existence of the return spring 204, the first clamping plate 206 will have elasticity. When it contacts the bearing, if the bearing is not at the center point, the first clamping plate 206 that contacts first will slowly shrink, and while initially limiting the bearing, it will not cause the bearing to deviate, until the other first clamping plates 206 contact the bearing in turn, and at the same time, as the linkage block 203 continues to move, the second clamping plate 207 is also opened to complete the limit fixation of the bearing to ensure that the bearing is stably fixed.

[0048] Example 2, refer to Figure 1-3 In order to solve the existing problem of overheating and difficulty in removing the finished bearing in this embodiment, based on the same concept as the above-mentioned embodiment 1, the quick fixing fixture for the bearing also includes:

[0049] The blanking component 300 also includes a first arc block 301, which is located above the device body 101. A connecting plate 302 is connected to the inner side of the first arc block 301. The connecting plate 302 cooperates with the first arc block 301 to complete the limiting and fixing of the bearing. A driving rod 303 is also connected to the bottom of the first arc block 301. A second cylinder 304 is connected to the bottom of the driving rod 303. The first arc block 301 is automatically driven to rise by the second cylinder 304, thereby driving the bearing to automatically rise for easy disassembly.

[0050] Connecting plates 302 are evenly and equidistantly distributed on the inner side of the first arc block 301. The first arc block 301 is connected to the device body 101 by sliding connection. The connecting plates 302 and the piston rod 202 are staggered. The first arc block 301 cooperates with the connecting plates 302 to limit the position of bearings of any size, thereby facilitating subsequent bearing disassembly work.

[0051] The first arc block 301 is installed in an integrated manner with the driving rod 303, and the driving rod 303 is connected to the second cylinder 304 in a piston connection. The first arc block 301 is installed in an integrated manner with the sliding rod 305, and the sliding rod 305 is a telescopic structure. The driving rod 303 drives the first arc block 301 to rise and fall, so that the overheated bearing above the first arc block 301 is raised and lowered, thereby facilitating the unloading of the bearing.

[0052] The specific working principle is: as mentioned above, after processing, turn on the switch of the second cylinder 304, so that the second cylinder 304 drives the first arc block 301 to rise through the driving rod 303, so that the first arc block 301 drives the connecting plate 302 to rise, and then the first arc block 301 pushes the bearing to rise when it rises, so that the bearing and the piston rod 202 are above different horizontal lines, and at the same time, when the first arc block 301 rises, the sliding rods 305 on the other two sides slide against each other to ensure the stability of the first arc block 301, and finally take out the processed bearing.

[0053] Example 3, refer to Figure 4-5 In order to solve the problem that the first arc block 301 may cause the bearing to move during the lifting process, in this embodiment, based on the same concept as the first embodiment, the quick fixing fixture for the bearing also includes:

[0054] The anti-slip component 400 also includes a second arc block 401, which is located above the driving rod 303. The outer side of the second arc block 401 is connected to an auxiliary block 402, and the auxiliary block 402 cooperates with the baffle 403 to limit and fix the bearing to ensure that the bearing does not move and fall. The interior of the auxiliary block 402 is connected to the baffle 403, and a movable block 404 is arranged above the baffle 403. Insert blocks 405 are connected to both sides of the movable block 404. The movable block 404 is limited so that the baffle 403 is retracted into the auxiliary block 402 when not in use.

[0055] Auxiliary blocks 402 are evenly and equidistantly distributed on the outside of the second arc block 401. The auxiliary block 402 is connected to the device body 101 by sliding connection, and the auxiliary block 402 is connected to the baffle 403 by rotating connection. The auxiliary block 402 cooperates with the baffle 403 to limit the bearing to prevent the bearing from falling during the feeding process and causing a safety accident.

[0056] The width of the movable block 404 is greater than that of the auxiliary block 402. The movable block 404 and the insertion block 405 are installed in an integrated manner. The insertion block 405 and the device body 101 are connected in a sliding manner. Through the cooperation between the movable block 404 and the insertion block 405, the movable block 404 can limit and fix the baffle 403 to prevent the baffle 403 from affecting the work when not in use.

[0057] The specific working principle is: as mentioned above, when the second arc block 401 is working, the movable block 404 is moved so that it slides above the device body 101 through the insertion block 405, and the movable block 404 is moved to a position where it is separated from the auxiliary block 402, and the limit on the baffle 403 is released. The torsion springs on both sides of the rear baffle 403 drive the baffle 403 to reset. At this time, the second arc block 401 is driven to rise through the second cylinder 304. Due to the limit of the baffle 403, the bearing will not be separated from the second arc block 401, thereby preventing safety accidents.

[0058] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
