In this technical solution, the bracket assembly 100 may include a bracket body 110, a guide rod 120, and a sliding member 130, where the guide rod 120 and the electromagnetic assembly 200 are disposed on the bracket body 110, so that the bracket assembly 100 may constrain positions of the guide rod 120 and the electromagnetic assembly 200, improving stability of the guide rod 120 and the electromagnetic assembly 200, the sliding member 130 is slidably disposed on the guide rod 120, and the guide rod 120 is disposed along an extending direction of the carrier wall 201 of the electromagnetic assembly 200, so that the sliding member 130 may adjust a position relative to the carrier wall 201 by sliding along the guide rod 120; the driving assembly 300 is arranged on the sliding member 130, so that the driving assembly 300 and the pressing member 400 can both move along with the sliding member 130, further the position flexibility of the pressing member 400 can be improved, the pressing member 400 can conveniently correspond to different positions on the carrying wall 201, and the driving assembly 300 can be driven to abut against the workpieces 10 'to be processed at different positions on the carrying wall 201, so that the adaptability of the workpiece fixing device to the workpieces 10' to be processed with different sizes can be improved.
It is understood that the direction in which the driving assembly 300 drives the pressing member 400 may be different from the arrangement direction of the guide bars 120, so that the positional flexibility of the pressing member 400 may be further improved.

Based on the above-mentioned arrangement, in practical application, if the position of the pressing member 400 relative to the carrying wall 201 needs to be adjusted, the positioning member 140 may be in an unlocked state, so that the sliding member 130 may slide relative to the guide rod 120, and after the pressing member 400 is adjusted in place, the positioning member 140 may be in a locked state, so as to avoid the pressing member 400 from further generating displacement relative to the carrying wall 201, and further ensure the positioning effect of the pressing member 400 on the workpiece 10' to be processed.
It should be understood that the specific limiting manner of the positioning element 140 may be various, such as structural limiting, magnetic force adsorption limiting, etc., and may be specifically set according to practical requirements, which is not limited herein.
In some examples, the thickness of the press 400 is less than or equal to 20mm in a direction perpendicular to the load bearing wall 201.

It will be appreciated that, as shown in fig. 3, after the plate thickness exceeds a certain range, the magnitude of the magnetic force applied to the plate member is reduced along with the change of the plate thickness, and similarly, the magnetic force applied to the pressing member 400 in the magnetic field of the electromagnetic assembly 200 is difficult to follow the increase of the thickness of the pressing member 400 along the direction perpendicular to the carrying wall 201, so that in practical application, the thickness of the pressing member 400 may be specifically set according to practical requirements, for example, the thickness of the pressing member 400 along the direction perpendicular to the carrying wall 201 may be set to be 2mm, 5mm, 10mm, etc., which is not limited herein.
In some examples, the side of the press 400 facing the carrier wall 201 is formed with a rounded structure.
In this technical solution, a rounded corner structure may be formed on a side of the pressing member 400 facing the carrying wall 201, and it may be appreciated that a side of the pressing member 400 facing the carrying wall 201 may be used to abut against the workpiece 10 'to be processed, so that, based on the foregoing arrangement, the corner structure of the side of the pressing member 400 facing the carrying wall 201 may be reduced, thereby reducing the possibility that the pressing member 400 damages the workpiece 10' to be processed, which is beneficial to further improving the processing quality and the production yield, and reducing the production cost.

In this technical solution, the pressing member 400 may be hinged to the output end of the driving assembly 300, so that the pressing member 400 may rotate relative to the output end of the driving assembly 300, so that the pressing member 400 has relatively high flexibility, and is convenient to adjust the posture of the pressing member 400 relative to the workpiece 10 'to be processed, and further, in the case that the pressing member 400 abuts against the workpiece 10' to be processed, the contact area between the pressing member 400 and the workpiece 10 'to be processed may be adjusted by rotating the pressing member 400, which is beneficial to improving the fixing effect of the pressing member 400 on the workpiece 10' to be processed.
It will be appreciated that as the number of uses of the press 400 increases, the amount of surface wear of the press 400 increases, and the tightness of the fit of the press 400 to the workpiece 10' to be machined tends to be degraded. Based on the above arrangement, the pressing member 400 can have good posture self-adapting capability, that is, the pressing member 400 is easy to adjust to a higher stable posture under the constraint of an external structure and the driving of external force, so that under the condition that the pressing member 400 is pressed against the workpiece 10' to be processed, if the pressing member 400 is subjected to the magnetic force applied by the electromagnetic assembly 200 or other external force capable of driving the pressing member 400 to further approach the electromagnetic assembly 200, the pressing member 400 is easy to automatically adjust to a more stable posture in a mode of rotating relative to the output end of the driving assembly 300, thereby ensuring the fixing effect of the pressing member 400 on the workpiece 10' to be processed, reducing the loosening probability of the workpiece 10' to be processed, reducing the influence of abrasion problem on the pressing member 400, being beneficial to prolonging the service life of the pressing member 400 and reducing the maintenance cost of the pressing member 400.
It can be appreciated that the hinge manner and the rotation direction between the pressing member 400 and the driving assembly 300 may be set in combination with actual requirements, for example, the pressing member 400 may be hinged to the output end of the driving assembly 300 through a universal hinge, so as to further expand the rotation direction of the pressing member 400 and improve the posture adjustment flexibility of the pressing member 400.
Illustratively, the drive assembly 300 may include a telescoping cylinder and a floating joint to which the floating structure is rotatably coupled to the telescoping end of the telescoping cylinder and the abutment 400 is coupled to the floating joint.
