[0001] The invention relates to the technical field of copper busbar surface quality detection, in particular to a copper busbar surface quality detection device. Background Art

[0002] Copper busbar is a high current conductive product, suitable for electrical engineering projects such as high and low voltage electrical appliances, switch contacts, and power distribution equipment.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

When the mass of the copper bar is too large, the copper bar presses the receiving device to rotate, so that the sliding pin leaves the pressure rod through the oblique groove. When the mass of the copper bar is too small, the copper bar presses the receiving device to rotate at a small angle, so that the detection needle of the electronic dial indicator does not contact the copper bar, and the quality of the copper bar is judged by the rotation of the receiving device, thereby eliminating the step of measuring the quality of the copper bar and speeding up the detection of the copper bar.

[0019] 2. In the copper busbar surface quality inspection equipment, the two electronic dial indicators are driven to move horizontally and circularly by the power motor, and the driving device drives the moving device to move at the same time, so that the trajectory of the detection needle of the electronic dial indicator on the copper busbar becomes a broken line, thereby increasing the contact area between the detection needle of the electronic dial indicator and the copper busbar, reducing the detection blind area, and improving the accuracy of the device in detecting the surface flatness of the copper busbar.

[0038] Example 1

[0039] See also Figure 1-Figure 7 As shown, the purpose of this embodiment is to provide a copper bar surface quality detection device, including a base 1, a receiving device 2 is symmetrically arranged on the upper side of the base 1, a driving detection device 3 is arranged between the two receiving devices 2, the base 1 is used to support the receiving device 2 and the driving detection device 3, the driving detection device 3 is used to measure the flatness of the steel bar surface, the receiving device 2 is used to receive the steel bar, and the driving detection device 3 is driven to move downward by the weight of the steel bar;

[0040] The base 1 includes a base frame 11, which is U-shaped. The receiving device 2 includes two pressure rods 21, one end of which is fixed with a receiving rod 22. The position where the pressure rod 21 and the receiving rod 22 are connected is hinged at one end of the base frame 11, and the pressure rod 21 and the receiving rod 22 are fixed together to form a fishhook shape, so that when the receiving rod 22 is driven to flip by the weight of the copper bar, the receiving rod 22 drives the pressure rod 21 to press the driving detection device 3, so that the driving detection device 3 moves downward and approaches the copper bar, so that the device for detecting the flatness of the copper bar on the driving detection device 3 contacts the copper bar. At the same time, considering that the copper bar needs to be received when placing it, a receiving plate 27 is rotatably connected between the two receiving rods 22, and the receiving plate 27 is used to receive the steel bar. When the copper bar is placed, the side wall of the receiving plate 27 contacts the side edge of the copper bar, so as to ensure the stability of the placement of the copper bar.

[0041] The driving detection device 3 includes a driving device 31 and a moving device 32 installed on the driving device 31, and the driving device 31 is used to drive the moving device 32 to move, so that the detection needle on the moving device 32 that detects the surface of the copper bar moves on the copper bar;

[0042] The moving device 32 includes a moving block 321, a receiving frame 322 is provided at the lower side of the moving block 321, and electronic dial gauges 328 are provided on both sides of the receiving frame 322 near the bottom. When the driving device 31 moves downward, the detection needle of the electronic dial gauge 328 is in vertical contact with the surface of the copper bar.

[0043] Considering that the receiving device 2 needs to drive the driving detection device 3 to move up and down, and at the same time, the driving detection device 3 needs to detect the quality of the copper bar when measuring the surface flatness of the copper bar, so as to reduce the steps of copper bar detection and speed up the copper bar detection. Please refer to Figure 1-Figure 8 A sliding groove 23 is provided on the side wall between the two pressure rods 21, and the driving device 31 includes a receiving frame 311. The ends of the front and rear side walls of the receiving frame 311 are provided with sliding pins 315. At the same time, a sliding groove corresponding to the sliding pin 315 is provided on the side wall of the receiving frame 311, and one end of the sliding pin 315 is slidably set inside the sliding groove, and one end of the sliding pin 315 is slidably set inside the sliding groove 23, so that the pressure rod 21 and the receiving frame 311 are connected together through the sliding pin 315. When the receiving plate 27 receives the copper bar, the receiving plate 27 drives the receiving rod 22 to rotate around The receiving rod 22 rotates at the position hinged with the base frame 11. When the receiving rod 22 rotates, the receiving rod 22 drives the pressure rod 21 to rotate, so that one end of the two pressure rods 21 approaches each other. When one end of the two pressure rods 21 approaches each other, the two pressure rods 21 press down the sliding pin 315 through the lower slide groove 23, so that the sliding pin 315 slides downward along the track of the lower slide groove 23. The sliding pin 315 sliding downward drives the receiving frame 311 to move downward, and the downwardly moving receiving frame 311 drives the moving device 32 to approach and contact the copper bar, so that the moving device 32 detects the flatness of the surface of the copper bar.

[0044] At the same time, considering that the receiving device 2 needs to test the weight of the copper bar when receiving it, side guard plates 12 are fixed at both ends of the base frame 11, and hinge plates 13 are fixed on the side where the two side guard plates 12 are close to each other, and torsion springs 26 are fixed on both sides of the hinge plates 13. The other end of the torsion spring 26 is fixed at the position where the pressure rod 21 and the receiving rod 22 are connected. After the copper bar is placed on the receiving plate 27, the receiving rod 22 drives the pressure rod 21 to rotate. At this time, the rotating pressure rod 21 drives the torsion spring 26 to rotate, so that the torsion force on the torsion spring 26 increases. When the torsion force on the torsion spring 26 and the weight of the copper bar reach a balance, the receiving device 2 stops rotating. When the weight of the copper bar does not reach the specified weight, the flipping angle of the receiving device 2 is too small, and the sliding distance of the sliding pin 315 in the sliding groove 23 is short, so that the electronic dial indicator 328 cannot contact the surface of the copper bar. When the weight of the copper bar is too heavy, the copper bar drives the receiving device 2 to flip at an excessively large angle, so that the driving device 31 moves downward too far, which easily causes the electronic dial indicator 328 to over-contact with the copper bar. Considering that the excessive contact between the electronic dial indicator 328 and the copper bar is likely to cause damage to the detection needle of the electronic dial indicator 328, an oblique groove 24 and an oblique groove 25 are respectively opened at both ends of the sliding groove 23, and the sliding pin 315 slides in the sliding groove 23. One end of the pin 315 is away from the pressure rod 21 through the oblique groove 24 and the oblique groove 25. The oblique groove 24 is used for the sliding pin 315 to leave the pressure rod 21 through the oblique groove 24 when the pressure rod 21 rotates too much, so that the pressure rod 21 cannot press the driving device 31 downward, thereby making the electronic dial indicator 328 away from the copper bar. At the same time, after the copper bar is taken down, when the torsion spring 26 drives the pressure rod 21 to return to its original position, the sliding pin 315 enters the sliding groove 23 through the oblique groove 25, so as to facilitate the continuous use of the device. At the same time, considering that the sliding pin 315 entering the sliding groove 23 is easy to detach from the sliding groove 23, the oblique groove The slanted groove 24 and the oblique groove 25 are inclined in the direction away from each other, and the oblique groove 24 and the oblique groove 25 are inclined from the edge of the pressure rod 21 to the middle, so that the oblique groove 24 and the oblique groove 25 are in an inclined state, so that the sliding pin 315 cannot arbitrarily escape from the lower sliding groove 23, and at the same time, a thrust spring 316 is fixed at one end of the sliding pin 315, and the thrust spring 316 pushes the sliding pin 315 away from the receiving frame 311 to ensure that when the sliding pin 315 passes through the inclined surfaces of the oblique groove 24 and the oblique groove 25, the sliding pin 315 will not be stuck in position due to the inclined surfaces of the oblique groove 24 and the oblique groove 25, thereby ensuring the normal use of the device.

[0045] When the cam 315 is in the unlocked position, the locking cam 318 is in the unlocked position, and the locking cam 318 is in the unlocked position, so that the cam 315 can be unlocked easily.

[0046] At the same time, when the pressure rod 21 drives the driving device 31 to move downward, the sliding pin 315 slides in the sliding groove 23 and continues to approach the hinged position of the pressure rod 21, the receiving rod 22 and the base frame 11, so that the downward movement distance of the pressure rod 21 becomes shorter when the pressure rod 21 rotates at the same angle. As a result, when the rotation angle of the pressure rod 21 gradually increases, the speed at which the pressure rod 21 drives the driving device 31 to move downward becomes slower, thereby ensuring that when the electronic dial indicator 328 is about to contact the copper busbar, the detection needle on the electronic dial indicator 328 will not directly hit the copper busbar, thereby ensuring the normal use of the electronic dial indicator 328.

[0047] Considering the need to change the trajectory of the electronic dial gauge 328 detecting the copper bar surface, and increase the range of the electronic dial gauge 328 detecting the copper bar surface, refer to Figure 8-Figure 9, tooth plates 325 are symmetrically arranged on the receiving frame 322, a gear is meshed between the two tooth plates 325, a power motor 326 for driving the gear to rotate is arranged on the gear, sliding rods penetrating the side wall of the receiving frame 322 are fixed at both ends of the tooth plates 325, and bottom slide grooves 324 are symmetrically opened on the receiving frame 322, and a slider sliding in the bottom slide groove 324 is fixed at the bottom of the tooth plates 325, and the sliding position of the tooth plates 325 is limited by the slider to ensure the stability of the lateral movement of the tooth plates 325, and a mounting frame is fixed on one side of the slider 327, the electronic dial gauge 328 is connected to the inside of the installation frame 327, and the electronic dial gauge 328 is connected to the installation frame 327, so that the electronic dial gauge 328 is easy to replace. A limit plate 329 is set on the tooth plate 325, and both ends of the limit plate 329 are fixed on the receiving frame 322. The power motor 326 is installed on the limit plate 329. When the electronic dial gauge 328 needs to detect the flatness of the copper bar surface, the power motor 326 drives the gear to rotate, so that the gear drives the tooth plate 325 to move horizontally, and at the same time, the power motor 326 The rotating shaft rotates forward and reversely, thereby driving the tooth plate 325 to slide back and forth horizontally on the receiving frame 322, and driving the electronic dial gauge 328 to move back and forth on the copper bar. Considering that when the electronic dial gauge 328 slides on the copper bar, the entire surface of the copper bar needs to be measured, the receiving frame 311 is set as a frame structure, and the interior of the receiving frame 311 is symmetrically fixed with sliding rods 312, and the upper side of the receiving frame 311 is hinged with a threaded screw rod 313, the sliding rod 312 and the threaded screw rod 313 both penetrate the moving block 321 and extend out, and the threaded screw rod 313 A driving motor 314 is installed at one end of 13 to drive the threaded screw 313 to rotate along its axis. The rotating shaft of the driving motor 314 drives the threaded screw 313 to move, and the position of the moving block 321 is limited by the sliding rod 312, so that the moving block 321 slides along the axis position of the threaded screw 313, thereby changing the sliding trajectory of the electronic dial gauge 328 on the copper bar into a reciprocating folded corrugated shape, thereby increasing the contact range between the electronic dial gauge 328 and the copper bar, and improving the accuracy of the electronic dial gauge 328 in measuring the flatness of the copper bar;

[0048] When considering the copper busbar, refer to the different thickness of the copper busbar to be measured. Fig. 9 Threaded rods 323 are symmetrically arranged at both ends of the receiving frame 322, one end of the threaded rod 323 is rotatably arranged on the receiving frame 322, and one end of the threaded rod 323 is threadedly connected to the moving block 321. Before testing, by rotating the threaded rod 323, the threaded rod 323 is threadedly connected to the moving block 321, and the receiving frame 322 is driven close to or away from the moving block 321, so as to ensure the contact between the detection needle of the electronic dial indicator 328 and the surface of the copper busbar.
