In laser cladding processing, single-pass or multi-pass lapping experiments (cladding is completed at multiple positions and multiple angles) need to be performed on a plate-shaped workpiece, and the workpiece is generally directly placed on a rotary worktable or clamped by common bench clamps. When a non-horizontal lapping experiment needs to be performed, a workpiece is generally fixed by using a bench clamp according to a required angle, then the bench clamp is fixed on a rotary worktable, and the rotary worktable is adjusted to a required processing position. When the angle of the steel plate is adjusted, the bench clamp needs to be opened to clamp the workpiece again, and the inclined steel plate is clamped by the bench clamp, so that the inclination angle of the upper surface of the workpiece is difficult to determine, and the clamping is not stable enough.
In addition, since laser processing is a hot and fast cooling process, the accumulation and dissipation speed of heat have a great influence on the processing process. When a workpiece is horizontally placed for laser cladding processing, if the workpiece is directly placed on a rotary worktable, the heat conduction of the laser cladding processing is fast, and the analysis of the actual distribution condition of the laser heat on a steel plate is influenced; and when the clamp is placed on a common bench clamp, if the cutting surface of a workpiece is not flat, the clamping effect is poor, and the level is not easy to ensure.

the rotary table is provided with a groove, the lower end of the longitudinal section of the groove is arc-shaped, a rotary block which is in rotary fit with the groove is arranged in the groove, and a through hole is formed in the rotary block and positioned at the center of the arc; the rotary table is provided with a support, the support is provided with a cross shaft which is in rotating fit with the through hole, and the rotary block is provided with a clamping unit for clamping a workpiece; the rotary table is provided with a first electromagnet, and a first magnetic block attracted with the electrified first electromagnet is embedded in the rotary block;
the clamping unit comprises a clamping block fixed on one side of the upper end of the rotating block, a sliding groove facing the clamping block is formed in the upper end of the rotating block, a moving block is connected in the sliding groove in a sliding mode, a second magnetic block is arranged on the clamping block, and a second electromagnet which is attracted or repelled with the second magnetic block when the moving block is electrified is arranged on the moving block.
The working principle of the basic scheme is as follows: in the laser processing process, when a workpiece needs to be clamped, the tool can be adopted to complete the process. When the tool clamps a workpiece, the workpiece can be placed between the clamping block and the moving block, the second electromagnet is electrified to be attracted with the second magnetic block, and the moving block can slide along the sliding groove to be close to the clamping block after the second electromagnet is electrified and attracted with the second magnetic block, so that the workpiece is clamped tightly. After the workpiece is clamped, the rotary table and the rotary block can be rotated according to the requirement, so that the workpiece is adjusted to the required position.
When the rotary table is required to rotate, the telescopic rod and the supporting block are pressed downwards, so that the telescopic rod is shortened downwards, the rectangular hole in the fixing sleeve acts on the spiral strip in the inner cavity of the telescopic rod, the spiral strip can rotate to drive the rotating sleeve to rotate, and the short shaft is connected with the bottom plate in a rotating mode due to the fact that the rotating sleeve is fixedly connected with the short shaft, and the rotating sleeve can rotate to drive the short shaft to rotate.

In the process of processing a workpiece by adopting a laser cladding technology, the tool can be used for clamping the workpiece. The specific process is that the workpiece is placed between the clamping block 60 and the moving block 61, the second switch 66 is controlled to electrify the second electromagnet 65 to enable the second electromagnet 65 to be attracted with the second magnetic block 64, and the moving block 61 slides along the sliding groove 63 to be close to the clamping block 60 after the second electromagnet 65 is electrified and then attracted with the second magnetic block 64, so that the workpiece is clamped; in the process, the vibrator 67 can be started to vibrate the workpiece by a proper amount, so that the two ends of the workpiece are positioned in the clamping groove 62 more centrally along with the approach of the moving block 61 to the clamping block 60, and the workpiece is clamped more stably. After the workpiece is clamped, the vibrator 67 is turned off, and the turntable 40 and the rotary block 50 can be rotated as required to adjust the workpiece to a desired position and angle.
When the horizontal position of the workpiece needs to be adjusted, an acting force is applied to the supporting block 36, so that the telescopic rod 30 is shortened downwards, namely the upper supporting rod moves downwards along the inner part of the lower supporting rod, in the process, the rectangular hole 33 on the fixed sleeve 32 moves downwards along with the lower supporting rod and acts with the spiral strip 35, the spiral strip 35 can rotate and drive the rotary sleeve 34 to rotate, and the rotary sleeve 34 rotates and drive the short shaft 20 to rotate.

Laser cladding processing generally requires melting another workpiece, placing another workpiece on the first clamping plate 71, rotating the screw 74, and sliding the second clamping plate 73 down along the support plate 70 to close the first clamping plate 71 by the screw 74 and the screw 75 acting on the second clamping plate 73. After the position of the workpiece on the clamping unit is adjusted, the piston of the cylinder 76 can be controlled to extend or contract, so that the position of the fulcrum plate 70 is changed, and the workpiece on the first clamping plate 71 and the second clamping plate 73 is adjusted to a required position.
After the positions and the angles of the two workpieces are adjusted, the laser cladding processing technology can be utilized to carry out laser cladding processing on the workpieces, if multi-pass or single-pass lapping needs to be carried out on the workpieces, the positions and the angles of the workpieces can be adjusted by applying acting force on the upper supporting rod and the supporting block 36 and controlling the rotating block 50 to rotate after the first electromagnet 43 is powered off. After the laser cladding processing of the workpiece is completed, the second switch 66 can be used for switching the energization direction of the second electromagnet 65 to reverse, so that the magnetic pole change of the second electromagnet 65 is repellent to the second magnetic block 64, the moving block 61 slides along the sliding groove 63 to be far away from the clamping block 60, and the workpiece can be conveniently taken out of the clamping unit.
