When decorative boards with different sizes need to be loaded, the rotary disc 409 drives the chuck 405 to rotate under the control of the controller, the support shafts 403 are driven by the chuck 405 to approach or separate from each other, when the two support shafts 403 approach each other, the screw rods approach each other under the drive of the support shafts 403, and then the two driven gears 406 extrude the power gear, the positioning motor 407 slides on the slide rail 408 under the drive of the power gear, the positioning motor 407 enables the power gear to be always meshed with the driven gears 406 under the support of the tensioning spring, and when the two support shafts 403 separate from each other, the positioning motor 407 moves under the support of the tensioning spring to enable the power gear to be meshed with the driven gears 406.
After loading board 401 down moved under the drive of back shaft 403, scraper blade 402 supported on base 1 up end, later, chuck 405 rotated, made scraper blade 402 scrape on base 1 up end, concentrated, scraper blade 402 on two loading boards 401 mutually supported and cleared up, concentrated the piece on the base 1, made things convenient for clearance mechanism (not drawn in the figure) among the compressive strength detection device to clear up the piece.
The working principle of the invention is as follows:
place the decorative board on two loading boards 401, loading board 401 carries out the centre gripping to the decorative board, later, the pressure is examined motor 203 and is made the lead screw rotate through rotating, presses pipe 202 to make pressure under the effect of lead screw examine axle 301 downstream or upstream, makes mainboard 303 and expansion board 304 be close to the decorative board and support on the decorative board.
When the force-bearing area needs to be changed, the sliding plate 3013 moves down on the inner shaft 3012, and when the sliding plate 3013 moves down on the inner shaft 3012, the resistance of the slide rheostat 3014 connected to the circuit becomes small, so that the alternating current introduced into the coil 3016 becomes large, further the alternating magnetic field generated by the coil 3016 becomes strong, the magnetic induction line passes through the induction plate 3015, so that an eddy current is generated on the induction plate 3015, further a reverse magnetic field is generated on the induction plate 3015, the induction plate 3015 and the coil 3016 are mutually repelled, further the inner shaft 3012 is difficult to be compressed into the outer shaft tube 3011, and thus the pressure detection range of the pressure detection shaft 301 is enlarged;
the adjusting rod 302 slides down from the inner shaft 3012 under the driving of the sliding plate 3013, the adjusting rod 302 pushes the plate box 305 outwards to enable the expansion plate 304 to extend out of the plate box 305, then the lifting block 308 loses the extrusion of the plate box 305, the limiting spring enables the gear plate 307 to abut against the limiting gear, the gear plate 307 is meshed with the limiting gear, the gear plate 307 enables the expansion plate 304 and the main plate 303 not to rotate relatively, and a complete pressing plate is formed between the expansion plate 304 and the main plate 303 and between the expansion plate 304 and the expansion plate 304, so that the area of the whole pressing plate is changed, and the pressure resistance detection of different stress areas can be carried out on the decorative plate.
When the sliding plate 3013 moves upward, the resistance of the circuit connected to the sliding rheostat 3014 increases, so that the alternating current flowing into the coil 3016 decreases, further the magnetic field generated by the coil 3016 weakens, the reverse magnetic field generated by the induction plate 3015 weakens, the repulsive force between the induction plate 3015 and the coil 3016 decreases, the inner shaft 3012 is pressed into the outer shaft 3011 more easily, and the measurement range of the pressure detection shaft 301 decreases;
when the adjusting rod 302 is driven by the sliding plate 3013 to move up on the inner shaft 3012, the board box 305 is driven by the adjusting rod 302 to approach the main board 303, and in the approach process, the board box 305 presses the lifting block 308, so that the lifting block 308 lifts the gear board 307 through a rope, the limitation of the gear board 307 on relative rotation is further removed, the expansion board 304 below the board box 305 and another expansion board 304 rotate relatively and then are put into the board box 305, the area of the whole pressing board is changed, and the pressing detection of different stress areas can be performed on the decorative board.
When the decorative boards with different inclination angles need to be subjected to compression resistance detection, the positioning motor 407 works to enable one supporting shaft 403 to move upwards and the other supporting shaft 403 to move downwards, when the support shaft 403 moves upwards, the posture plate 404 moves upwards under the drive of the arc-shaped plate, and then the bearing plate 401 rotates upwards on the supporting shaft 403, so that the bearing plate 401 tilts on the supporting shaft 403, when the supporting shaft 403 moves downwards, the arc-shaped plate of the posture plate 404 is driven to move downwards, and then the bearing plate 401 rotates downwards on the supporting shaft 403, so that the bearing plate 401 tilts on the supporting shaft 403, the two bearing plates 401 cooperate with each other to adjust the tilt angle of the decorative plate, when the decorative board takes place the slope, the clamp plate also carries out corresponding rotation under the drive of adjusting pole 302, makes clamp plate and decorative board parallel, and later, the clamp plate pushes down perpendicularly, realizes the resistance to compression detection to the different inclination of decorative board.
When decorative boards with different sizes need to be loaded, the rotating disc 409 drives the chuck 405 to rotate, the support shafts 403 are driven by the chuck 405 to be close to or away from each other, when the two support shafts 403 are close to each other, the screw rods are driven by the support shafts 403 to be close to each other, then the two driven gears 406 extrude the power gears, the positioning motor 407 is driven by the power gears to slide on the slide rails 408, the positioning motor 407 enables the power gears to be always meshed with the driven gears 406 under the support of the tensioning springs, and when the two support shafts 403 are far from each other, the positioning motor 407 moves under the support of the tensioning springs to enable the power gears to be meshed with the driven gears 406.
When needing to clear up the piece, loading board 401 is under the drive of back shaft 403, supports on base 1 up end until scraper blade 402, and later, chuck 405 rotates, makes scraper blade 402 scrape on base 1 up end and get, concentrate, and scraper blade 402 on two loading boards 401 mutually supports and clears up, concentrates the piece on the base 1, makes things convenient for the clearance mechanism among the compressive strength detection device to clear up the piece.
