The working principle is as follows:
a positioning stage:
referring to the drawings, the specific implementation process shown in fig. 1 to 6 is as follows:
firstly, the clamp for processing the bearing is installed in a bearing processing workshop, a power supply in the workshop is connected, a common bearing is cast by gray cast iron, but the gray cast iron has poor plasticity and high brittleness and is not suitable for grinding, and a bearing seat is used for supporting shaft parts, in order to meet the matching requirement of an outer ring of a rolling bearing and a bearing hole or the matching of an outer circle of a sliding bearing and the bearing hole, the bearing seat needs to be processed such as boring, polishing and the like, in order to reduce the condition that the quality of processing is poor due to the swinging of the bearing seat in the processing process, the swinging of the bearing seat needs to be reduced, then, the bearing seat to be processed is placed on a bearing table 1 through a manipulator in the workshop, the bearing seat is positioned at the middle position of the bearing table 1, then, the first electric actuator 101 is controlled to be started, the first electric actuator 101 is extended, the connecting plate 102 is synchronously driven to drive the U-shaped plate 103 to move backwards, the U-shaped plate 103 drives the two air bags 105 to move backwards through the supporting rod 104, the two air bags 105 move towards the direction close to the bearing seat until the air bags 105 are contacted with the bearing seat, and the first electric actuator 101 is extended, and the two supporting rods 104 simultaneously drive the U-shaped air bags 105 to move backwards to close the bearing seat, and position the back plate 301.
After the front and rear limiting is completed, in order to stably fix the bearing seat, the bearing seat needs to be positioned in the middle of the bearing platform 1, and therefore the bearing seat needs to be positioned left and right, at this time, the two second electric actuators 201 are controlled to be started, the two second electric actuators 201 contract to synchronously drive the cross beam 202 to drive the top cover 203 to move downwards until the top cover 203 contacts with the bearing seat, if the position of the bearing seat is not in the middle of the bearing platform 1, when the top cover 203 moves downwards, one side of the top cover 203 preferentially contacts with the bearing seat, so that the upper part of the top cover 203 rotates in the center of the first through groove 20201, the top cover 203 drives the two contact blocks 205 to rotate through the sliding plate 204, the upper part of the sliding plate 204 contacts with the bottom of the cross beam 202, along with the rotation of the top cover 203, the first elastic member 206 on the sliding plate 204 is stretched, and meanwhile, the sliding plate 204 slides downwards relative to the top cover 203 to synchronously drive the contact blocks 205 to move, as the cross beam 202 descends, the arc surface of the lower part of the contact block 205 contacts the upper part of the bearing seat, the contact block 205 pushes the bearing seat to the middle of the bearing seat 1, at this time, the first elastic member 206 gradually recovers, and at the same time, the opening of the top cover 203 swings downwards until the opening of the top cover 203 vertically descends, then the cross beam 202 continues to descend, both the contact blocks 205 contact the upper part of the bearing seat, the first elastic member 206 is stretched again, the two contact blocks 205 retreat into one second through groove 20301, each of the two contact blocks 205 drives one sliding plate 204 to move upwards, the deformation part 20401 of the sliding plate 204 contacts the cross beam 202, the deformation part 20401 is an arc reed, and as the cross beam 202 presses downwards, the deformation part 20401 contacts the lower surface of the cross beam 202 with the arc top thereof, the deformation part 20401 begins to deform, because the two deformation parts 20401 splay open, the descending degree of the cross beam 202 is larger, the larger the deformation of the two deformation parts 20401 is, the larger the downward pressure applied to the bearing seat by the contact block 205 by the sliding plate 204 is, the better the fixing effect of the bearing seat is, until the inner arc surface of the top cover 203 contacts with the bearing seat, the top cover 203 also participates in the pressing-down fixation of the bearing seat, the two second electric actuators 201 are controlled to be closed, the left and right positioning of the bearing seat is completed at the moment, the bearing hole is aligned with the round hole 30101, and the quick positioning fixation of the bearing seat is completed.
A fixing stage:
referring to the drawings, the specific implementation process shown in fig. 7 to 9 is as follows:
because the bearing seat can shake when the tool is used for processing a bearing hole in the process of processing the bearing seat, the bearing seat can be fixed only by the pressure of the top cover 203 from top to bottom, and after the bearing seat works for a period of time, the connecting position of the top cover 203 and the cross beam 202 is greatly worn, bolt connecting parts at two sides of the bearing seat also need to be fixed, because the two air bags 105 are contacted with the front part of the bearing seat when the bearing seat is fixed in the prior art, and the bearing seat is pressed downwards and limited by the top cover 203 at the moment, the first electric actuator 101 is controlled to be started first, the first electric actuator 101 contracts and synchronously drives the two air bags 105 to move forwards, so that the two air bags 105 are separated from the bearing seat, the first electric actuator 101 is controlled to be closed, then the two power assemblies 302 are controlled to be started, the output shafts of the power assemblies 302 rotate, and the pressure plates 304 are synchronously driven by the first rotating shafts 303 to rotate, until the lower surface of the pressing plate 304 contacts with the bolt connecting parts at two sides of the bearing seat, then the first electric actuator 101 is controlled to be started, the first electric actuator 101 extends to synchronously drive the two supporting rods 104 to respectively enter a first U-shaped groove 1002, the two supporting rods 104 respectively drive a roller 402 to move backwards through the rotating seat 401, at this time, the pressing plate 304 is parallel to the bearing platform 1, therefore, when the roller 402 moves backwards, the supporting rods 104 drive the rotating seat 401 to enter a second U-shaped groove 30401, meanwhile, the roller 402 enters a wedge-shaped groove 30402, the roller 402 moves backwards along with the extension of the first electric actuator 101, the roller 402 moves backwards relative to the wedge-shaped groove 30402, namely, the front part of the pressing plate 304 is pressed downwards by the roller 402, at this time, the locking of the front part of the pressing plate 304 is completed through the supporting rods 104, the rotating seat 401 and the roller 402, and the movement of the roller 402 in the wedge-shaped groove 30402 also presses the front part of the pressing plate 304 downwards, and the clamping and fixing effect of the pressure plate 304 on the bolt connecting part of the bearing seat is further enhanced, and the two power assemblies 302 are controlled to be closed.
And (3) heat dissipation impurity removal stage:
referring to the drawings, the specific implementation process shown in fig. 10 to 12 is as follows:
