Referring to fig. 1 and 7, the regulated power supply 4 and the first conductive plate 707, the current detector 5 and the third conductive plate 709 are electrically connected through the first wire 701 and the second wire 702, respectively, and the farthest distances between the second conductive plate 708 and the first conductive plate 707 and between the fourth conductive plate 710 and the third conductive plate 709 are the extendable distances of the telescopic cylinder 3.
In the present embodiment, by providing such a structure, when the telescopic cylinder 3 is fully extended, the fourth conducting strip 710 and the second conducting strip 708 respectively contact with the third conducting strip 709 and the first conducting strip 707, so that the electrical connection between the regulated power supply 4, the positive plate 610, the copper bar, the negative plate 618 and the current detector 5 can be realized.
Referring to fig. 1 and 7, the thickness of the positive plate 610 and the negative plate 618 is equal to the length of the lead screw 608, and when the positive plate 610 and the negative plate 618 are at the initial position, the distance from the top of the positive plate 610 to the bottom of the worktable 1 is smaller than the height of the worktable 1.
In the embodiment, when the limiting frame 609 moves to the highest position along the lead screw 608 by the arrangement of the structure, the limiting frame 609 drives the positive plate 610 and the negative plate 618, so that the positive plate 610 and the negative plate 618 are convex relative to the top of the workbench 1, and thus the positive plate 610 and the negative plate 618 can be in contact with the copper bar placed on the top of the workbench 1.
The working principle of the invention is as follows: when the device is used, a copper bar to be detected can be placed at the top of the workbench 1, then the telescopic cylinder 3 is started, when the telescopic cylinder 3 extends, the H-shaped connecting block 616 can be pushed to move downwards, meanwhile, the H-shaped connecting block 616 can drive the fourth conducting strip 710 and the second conducting strip 708 to move downwards along the inner walls of the first connecting bin 704 and the second connecting bin 705 through the first sleeve 703 and the second sleeve 706, when the pressing plate 619 moves downwards, the stop block 625 is separated from the limit block 624, at this time, the ratchet 628 loses the limit of the stop block 625 and is buckled on the outer side of the ratchet 623 under the action of the torsion spring 627, meanwhile, the H-shaped connecting block 616 can stir the first straight gear 603 through the second rack 626 to rotate, when the first straight gear 603 rotates, the first bevel gear 602 can drive the first bevel gear to rotate, when the first bevel gear 604 rotates, the second bevel gear 605 can be driven to rotate, therefore, the second bevel gear 605 drives the half-gear turntable 606 to rotate, when the half-gear turntable 606 rotates, the sleeve rod 612 limited by the limiting rod 613 can be driven by the positioning column 611 to move towards the workbench 1, so that the side plate 629 can be driven to move, so that the copper bar on the top of the workbench 1 can be pushed by the side plate 629, the vertical central axis of the copper bar and the vertical central axis of the workbench 1 are in a superposed state, so that the pressing of the copper bar by the subsequent pressing plate 619 is facilitated, in the process, if the copper bar is corrected by the side plate 629, the copper bar cannot be in contact with the positive plate 610 and the negative plate 618, so that the friction with the positive plate 610 and the negative plate 618 in the process of correcting the copper bar is prevented, the service lives of the positive plate 610 and the negative plate 618 are prolonged, when the half-gear turntable 606 does not rotate by one hundred eighty degrees, at this time, the distance of the sleeve rod 612 pushing the side plate 629 to move is converted into the contraction distance of the first expansion spring 615, when the half-gear turntable 606 rotates one hundred eighty degrees, the half-gear turntable 606 continues to rotate, at this time, the outer side of the half-gear turntable 606 is just meshed with the outer side of the second spur gear 607, at this time, the second spur gear 607 rotates along with the rotation of the half-gear turntable 606, so that the lead screw 608 rotates along with the rotation of the second spur gear 607, so that the limiting frame 609 moves upwards along the lead screw 608 to push the positive plate 610 and the negative plate 618 to move upwards, so that the positive plate 610 and the negative plate 618 jack up the copper bar at the top of the workbench 1, the tops of the positive plate 610 and the negative plate 618 are in contact with the copper bar, the bottom of the copper bar is separated from the top of the workbench 1, at this time, the expansion cylinder 3 continues to push the pressing plate 619 to move downwards, when the pressing plate 619 contacts with the top of the copper bar in the downward movement process, the pressing plate 619 is obstructed by the copper bar, the telescopic cylinder 3 extends continuously at the moment, so that the H-shaped connecting block 616 moves downward relative to the pressing plate 619 to extrude the second telescopic spring 620 between the H-shaped connecting block 616 and the pressing plate 619, the third spur gear 622 rotates along the first rack 621, the ratchet 623 rotates along with the rotation of the third spur gear 622 in the process, meanwhile, the ratchet 623 stirs the ratchet 628 to swing, the ratchet 628 limits the rotation of the ratchet 623 in the direction, so that the pressing plate 619 limits the pressing of the copper bar with different thicknesses, when the telescopic cylinder 3 extends completely, the positioning mechanism 6 can press and limit the copper bar at the top of the workbench 1, and the fourth conducting strip 710 and the second conducting strip 708 at the moment are respectively connected with the third conducting strip 709, first conducting strip 707 contact, so alright realize constant voltage power supply 4, positive plate 610, the copper bar, negative plate 618, current detector 5's electric connection, later alright detect out the resistance size of copper bar through the data that current detector 5 shows, accessible telescopic cylinder 3's shrink makes fourth conducting strip 710 and third conducting strip 709 after detecting the completion, second conducting strip 708 and first conducting strip 707 separation, so alright realize the outage and handle, so that make equipment go on with the detection of copper bar in step to the spacing of copper bar, so as to increase the detection efficiency of equipment to copper bar resistance, also alleviateed staff's intensity of labour simultaneously, simultaneously positive plate 610, negative plate 618 can be income workstation 1 once more, later can take off the copper bar after detecting, when telescopic cylinder 3 contracts completely, stopper 625 just can press stopper 624, so alright make ratchet 628 and the separation of ratchet 623 outside, first rack 621 at this moment just can lose spacingly, thereby make second telescopic spring 620 promote the clamp plate 619 and restore, thereby convenience is provided for subsequent use.
