The scheme has the following working processes:

when the bracket is used for clamping a regular workpiece with light weight, the supporting area of the supporting platform 13 is firstly required to be adjusted according to the size of the workpiece and the size of a processing device, the elastic pin 9 is only required to be pulled up to move the fixing ring 6 during adjustment, the connecting rod 10 can push the first sliding plate 15 and the second sliding plate 16 to move outwards when the fixing ring 6 ascends, the supporting area is enlarged, the first sliding plate 15 and the second sliding plate 16 retract when the fixing ring 6 descends, the workpiece can be matched with the limiting hole 8 to be fixed after being adjusted to a required state, then the workpiece is placed on the supporting platform 13, the fixing ring 6 is moved and adjusted to compress the workpiece, the workpiece can gradually move towards the center shaft of the supporting platform 13 to finally realize the clamping when being clamped by the fixing pieces 19 in four directions, and is stably clamped by the fixing piece 19, and finally the servo motor 2 is started to adjust the workpiece to the height of the processing point.

When the shape of the workpiece is irregular and heavy, the plurality of fixing members 19 need to be controlled to move, and the moving distances are different, at this time, the second hydraulic rod 26 needs to be used for controlling the moving distance of each fixing member 19 in the first sliding groove 25, so as to clamp the workpiece with the irregular shape, specifically: the height of the fixing ring 6 is adjusted to ensure that the first sliding plate 15 and the second sliding plate 16 are opened at proper angles, the workpiece is placed on the top of the support platform 13 and is placed at the axle center of the support platform 13 as far as possible, the first hydraulic rod 18 is started, the fixing piece 19 is controlled to be lifted or lowered, so that the clamping position of the fixing piece 19 to the workpiece is the most reasonable, at the moment, the second hydraulic rod 26 is started to control the limiting block 24 to move towards one end of the workpiece, after the top fixing piece 19 is contacted with the workpiece, the magnetic fixing block 22 is continuously contacted with one end of the workpiece and the value of the pressure sensor is gradually increased, when the pressure value of the pressure sensor reaches the set threshold value, the second hydraulic rod 26 stops moving, at the moment, the electromagnet in the electromagnetic limiting column 21 starts and repels the magnetic fixing block 22, the clamping device is in close contact with the workpiece, and can simultaneously control the movement of the fixing piece 19 in multiple directions so as to clamp the workpiece.

When need process the top surface of work piece when in actual use, and the top surface and the bottom surface of work piece are not parallel, place the bottom surface of work piece this moment on a supporting bench 13 the top surface of back work piece in the tilt state, this bracket just not only need possess and press from both sides tight rising function, still need control the work piece upset when pressing from both sides tightly, makes its top surface be in the horizontality, can also control its and supporting bench 13 coaxial axle center better, and concrete operation is: as mentioned above, the height of the fixing ring 6 is controlled to control the opening degree of the first sliding plate 15 and the second sliding plate 16, and then the workpiece is placed on the top of the supporting platform 13, taking the working process of the fixing piece 19 at the lowest end of the workpiece as an example, at this time, the second hydraulic rod 26 is started and drives the limiting block 24 to move towards the workpiece end, when the fixing piece 19 contacts with the workpiece and the value detected by the pressure sensor at the end of the magnetic fixing block 22 reaches the set pressure threshold, the second hydraulic rod 26 drives the limiting block 24 to move reversely, and simultaneously, the first hydraulic rod 18 drives the fixing piece 19 to move upwards, during the moving process, the fixing piece 19 just faces upwards along one side line of the workpiece, because the outer end of the fixing piece 19 is uniformly and circumferentially provided with a plurality of magnetic fixing blocks 22, the pressure sensors at the ends of the magnetic fixing blocks 22 close to the workpiece end can detect the value, when the pressure value of the pressure sensor at the topmost part drops to zero, the topmost magnetic fixing block 22 is proved to be separated from the workpiece at this time, the second hydraulic rod 26 and the first hydraulic rod 18 are controlled to stop control at this time, the current of the electromagnetic limiting column 21 is increased to control the line size of the electromagnetic limiting column, the numerical value of the pressure sensor reaches the set pressure threshold value at this time, then the linear distance between the end part of the workpiece and the second sliding plate 16 at this time is detected by the laser distance meter in the topmost magnetic fixing block 22, the vertical distance detected by the laser distance meter when the fixing pieces 19 clamp the end part of the top surface of the workpiece is detected in sequence through the process, the inclination condition of the top surface of the workpiece can be determined, the condition that the fixing pieces 19 at each position need to work is determined through statistics and calculation of the controller 33, so that the horizontal placement of the top surface of the workpiece can be realized, taking the vertical distance detected by the fixing pieces 19 as an example, the first hydraulic rod 18 is started and controls the fixing pieces 19 to move upwards, the workpiece is driven to turn over in the upward moving process of the fixing piece 19, the first hydraulic rod 18 opposite to the fixing piece 19 can synchronously control the fixing piece 19 to move downwards in the turning process so as to compensate the turning process of the workpiece, and as the outer ring of the supporting disk 20 is uniformly provided with the plurality of groups of magnetic fixing blocks 22, when some magnetic fixing blocks 22 are separated from the pressing state of the workpiece in the turning process of the workpiece, the upper magnetic fixing blocks 22 or the lower magnetic fixing blocks 22 can compensate the workpiece, so that the pressing state of the magnetic fixing blocks 22 on the workpiece is ensured constantly, and in the turning process, if the measured pressure value is lower than a set pressure threshold value, the lost pressure value can be compensated by only increasing the current in the electromagnetic limiting column 21 so as to increase the magnetism of the magnetic fixing blocks, the pressing state of the fixing piece 19 on the workpiece is ensured at the moment, and the clamping and turning work of the workpiece can be realized by sequentially controlling the movement of the fixing piece 19 at each position according to the process, and known from the working process, the clamping and fixing degree and precision can be increased by increasing the number of the fixing pieces 19 and the number of the electromagnetic limiting columns 21, so that the top surface of the workpiece is better leveled, and various machining is facilitated.

After the top surface of the workpiece is controlled to be horizontally arranged, the center shaft of the workpiece needs to be superposed with the center shaft of the support table 13, so that the workpiece can be processed more conveniently, and the method specifically comprises the following steps: the moving distance s of the limiting block 24 in the first sliding groove 25 can be well calculated by controlling the movement of the second hydraulic rod 26, the length of the connecting rod 10 is L, the distance from the bottom of the electric telescopic column 11 when the fixing ring 6 does not rise is L, and when the upward moving distance of the fixing ring 6 is x and the moving distance of the limiting block 24 controlled by the second hydraulic rod 26 is s, the distance y from the fixing part 19 to the central shaft of the supporting table 13 is as follows:

through the formula, the rising height l of the fixing ring 6 is fixed, but the moving distance s of the fixing piece 19 driven by the second hydraulic rod 26 is different, so the distance from the fixing piece 19 to the axis position in the supporting table 13 can be calculated through the formula, the difference value of the smaller end of the distance is subtracted from the half of the distance sum of the fixing pieces 19 at the opposite positions, namely the moving distance of the workpiece to the smaller end in the direction, at the moment, the clamping degree of the workpiece by the two fixing pieces 19 vertical to the moving direction is only needed to be controlled, namely, the current in the electromagnetic limiting column 21 is reduced to reduce the magnetic force, so that the repulsive force to the magnetic fixing block 22 is reduced, the clamping degree of the workpiece by the magnetic fixing block 22 is reduced, the pressure sensor is used for detecting the second pressure threshold value set by the pressure value reduction value, the pressure threshold value ensures that the magnetic fixing block 22 does not block the workpiece from moving in the other direction, can also play a role ofThe workpiece supporting function sequentially controls the movement of the workpiece in two directions through the method, the center axis of the workpiece is coincided with the center axis of the supporting table 13, and finally the thread lifting column 4 is started and drives the supporting table 13 to ascend to a processing position, so that the top surface of the workpiece can be conveniently processed by a processing part.

In conclusion, the adjustability of the universal bracket can be realized in an auxiliary mode through the cooperation between each part and the structure, the function of fixing the workpiece by the bracket is improved, the fixing mode is more variable, the adaptability is stronger, and the stability of the bracket is improved through the matching mode of limiting and screwing the threads.
