Specifically, the upper snap ring 32, the lower snap ring 312 and the turntable 2 are coaxial all the time, so that the positioning of the processing sample plate 7 is more accurate.
Specifically, the magnet 14 is fixed on one side of the sliding ejector block 5 close to the turntable 2, the attraction force of the magnet 14 is far greater than the gravity of the processing sample plate 7 and the friction force of the circular clamping block 38, the processing sample plate 7 can be tightly attracted, and the phenomenon that the position of the processing sample plate 7 is changed in the process of returning the clamping mechanism 3 to the original position, which causes inaccurate positioning, is prevented.
The working principle is as follows: when the processing template 7 is used, a processing template 7 is firstly taken and placed into the arc-shaped feeding hole 9, the processing template 7 rolls into the T-shaped slide rail 8, then slides to the position above the strip-shaped clamping block 313, then rolls into the lower annular groove 310, then hits the L-shaped lower connecting rod 37 and then is clamped and stopped in the lower annular groove 310, the sliding speed of the processing template 7 cannot be too high due to the existence of friction force, after the processing template 7 stops, the power supply of the electric supporting rod 318 is switched on, the electric supporting rod 318 begins to extend, the L-shaped lower connecting rod 37 is pushed to move upwards, the lower clamping ring 312 and the lower straight teeth 36 are driven to slide upwards, the gear 35 is driven to rotate, the gear 35 is also meshed with the upper straight teeth 34, and the upper straight teeth 34 slide in the concave frame 31 and drive the L-shaped upper connecting rod 33 and the upper clamping ring 32 to slide downwards; meanwhile, the sliding push rod 317 is gradually not contacted with the bottom of the L-shaped support 1 any more, the pressure applied to the thrust spring 316 is gradually released and pushes the sliding push rod 317 to rotate along the shaft, so that the sliding push rod 317 approaches to each other and drives the strip-shaped clamping block 313 to rotate to gradually clamp the processing sample plate 7, the processing sample plate 7 is prevented from falling off, and the strip-shaped clamping block 313 completely clamps the processing sample plate 7; meanwhile, when the lower clamping ring 312 moves upwards, the sliding connecting rods 314 gradually do not extrude the bottom of the L-shaped support 1 any more, the two sliding connecting rods 314 are gradually drawn close to each other due to the pulling force of the tension spring 320, the connecting block 315 is driven to gradually approach to each other, the circular clamping blocks 38 at the tops of the connecting blocks 315 are gradually close to each other and clamp the processing sample plate 7, when the rollers 15 on the inner sides of the circular clamping blocks 38 completely contact the processing sample plate 7, the sliding connecting rods 314 do not rotate at the moment, and the processing sample plate 7 is supported by the circular clamping blocks 38 to be in a vertical state; meanwhile, when the electric stay bar 318 extends to push the L-shaped lower connecting rod 37 and drives the L-shaped upper connecting rod 33 to move downwards, the hydraulic pipe 45 is compressed, the liquid outlet one-way valve 48 is communicated at the moment, the liquid inlet one-way valve 47 is closed, lubricating oil flows through the fixed pipe 43 and the liquid outlet hose 41 after being compressed from the bottom of the hydraulic pipe 45, enters the circular clamping block 38 close to the sliding top block 5, and is sprayed out of the oil nozzle 44 which is obliquely arranged to the side wall of the processing sample plate 7 for lubrication, so that the friction force in the spinning process is reduced to reduce the temperature of the processing sample plate 7; when the top of the processing template 7 is clamped by the lower clamping ring 312, at this time, the electric support rod 318 does not extend any more, then the sliding top block 5 is controlled to slide towards the processing template 7 in the sliding groove 10, when the magnet 14 on the sliding top block 5 tightly sucks the processing template 7, the electric support rod 318 is controlled to contract, at this time, the L-shaped lower connecting rod 37 moves downwards and drives the lower clamping ring 312 to move downwards, at this time, the two circular clamping blocks 38 clamp the processing template 7, because the rollers 15 are arranged in the adjacent side walls of the circular clamping blocks 38, the friction force between the circular clamping blocks and the processing template 7 is reduced, the suction force provided by the magnet 14 is large, the two circular clamping blocks 38 move downwards along with the lower clamping ring 312, finally separate from the processing template 7 under the rotation of the rollers 15, simultaneously, the lower straight teeth 36 slide downwards and drive the gear 35 to rotate, the gear 35 is also meshed with the upper straight teeth 34, so that the upper straight teeth 34 slide in the concave frame 31 and drive the L-shaped upper connecting rod 33 and the upper clamping ring 32 to slide upwards, until the original position is returned; when the L-shaped lower connecting rod 37 and the L-shaped upper connecting rod 33 are far away from each other, the hydraulic pipe 45 is stretched, the liquid outlet one-way valve 48 is closed, the liquid inlet one-way valve 47 is communicated, and lubricating oil flows into the bottom of the hydraulic pipe 45 from the oil suction pipe 46 to be stored for later use; when the electric stay bar 318 contracts to the bottom of the L-shaped support 1, where the sliding link 314 and the sliding push bar 317 contact the bottom of the L-shaped support 1, the pulleys 13 at the bottom of the sliding link 314 and the sliding push bar 317 roll along the bottom of the L-shaped support 1, driving the two sliding links 314 to move away from each other and stretch the tension spring 320, at this time, the connecting block 315 and the circular clamping block 38 also move away from each other, and the two sliding push bars 317 approach each other and press the thrust spring 316 on one side and drive the bar-shaped clamping block 313 to rotate to contact the T-shaped slide rail 8, at this time, the electric stay bar 318 does not contract any more, the power supply of the electric stay bar 318 is disconnected, and at the same time, the sliding top block 5 continues to slide inward to the pressing turntable 2, and then the rotating wheel arm 6 can be controlled to process the processing template 7.
