The embodiment further comprises a conveying device 1 and a lifting device 2, wherein the conveying direction of the conveying device 1 is perpendicular to the longitudinal guide rail 61, and a plurality of stop blocks 11 are arranged on the product contact surface of the conveying device 1 and used for preventing the product to be detected from sliding relative to the conveying device 1. The bottom of the conveyor 1 is provided with a support plate 12, and the support plate 12 is usually made of a stainless steel plate with a good gloss angle and used for supporting the conveyor 1.
Referring to fig. 7 and 8: the dotted line in fig. 7 indicates the conveyor belt 1, the material lifting device 2 includes an ascending section 21 and a horizontal section 22 which are connected in sequence, the height of the lower end of the ascending section 21 is lower than the upper surface of the conveyor device 1, the height of the higher end of the ascending section 21 and the height of the horizontal section 22 are both higher than the upper surface of the conveyor device 1, but lower than the upper edge of the stopper 11, so that the stopper 11 can still push the product to be tested to the horizontal section 22.
The horizontal section 22 is provided with a first supporting roller 23 which corresponds to the position of the feeding device 3 and is parallel to the conveying direction of the conveying device 1, and the first supporting roller 23 corresponds to the position of the feeding device 3, namely the first supporting roller 23 and the feeding device 3 are collinear, so that a product to be tested on the first supporting roller 23 can be directly pushed into the feeding device 3. The side of the material lifting device 2 is further provided with a feeding cylinder 28 arranged opposite to the feeding device 3, and the feeding cylinder 28 is used for pushing a product to be tested to the working range of the feeding device 3.
When the product that awaits measuring gets into bearing roller 23, can be blocked by the retaining ring of bearing roller 23 tip, in order to guarantee that the product that awaits measuring can enter into bearing roller 23 smoothly, the one end that the ascending section 21 is close to bearing roller 23 of this embodiment needs to adopt the design of liftable, and concrete structure can refer to fig. 7 to fig. 9:
During operation, the product to be tested is placed on the conveying device 1 in a state that the guide surface faces upwards, and the approximate axial position of the product is ensured during placement, namely the distance between the end part of the product and the edge of the conveying device 1 is within a certain range. The conveying device 1 conveys the products to be tested forwards, and when the products to be tested are conveyed to the ascending section 21, the products to be tested can stop moving under the blocking effect of the ascending section 21, so that the stop blocks 11 are in contact with two ends of the products to be tested, and the products to be tested can be perpendicular to the conveying direction of the conveying device 1. When the product to be tested is pushed to the horizontal section 22, the product to be tested enters the interior of the first carrier roller 23 in a state that the first carrier roller 23 is inclined (fig. 8), then the first carrier roller 23 is lifted through the sliding of the driving plate 26, so that the first carrier roller 23 is in a horizontal state (fig. 7), and the product to be tested is separated from the horizontal section 22. Then, the feeding cylinder 28 pushes the product to be tested to enter the working range of the feeding device 3 from the first carrier roller 23, the product to be tested is conveyed to the material supporting assembly under the clamping action of the two feeding wheels 34, and the two ends of the product to be tested are respectively supported by the two end material supporting assemblies 4, so that in the process that the product to be tested moves to the material supporting assembly, the second carrier roller 43 and the third carrier roller 53 need to be ensured to be in the equal height state, and the product to be tested can conveniently advance. After the two ends of the product to be tested are supported by the two carrier rollers two 43, the plurality of carrier rollers three 53 in the middle are also supported by the corresponding floating air cylinders 56, the supporting force of the floating air cylinders is related to the number of the carrier rollers three 53 and the quality of the product to be tested, the final purpose is to ensure that the supporting forces of all the carrier rollers two 43 and the carrier rollers three 53 for supporting the product to be tested are equal to the supporting force of the product to be tested, and the specific control method can be designed by a person skilled in the art according to the prior art. Wherein, the supporting force of the third idler roller 53 can be controlled by the air pressure of the corresponding floating air cylinder 56.
Because the second carrier roller 43 at the two ends is of an equal-height structure, when the second carrier roller 43 and the third carrier roller 53 complete the support of the product to be tested, the two ends of the product to be tested are in an equal-height state. Then, the second idler roller 43 is locked through the pneumatic clamp 45 and the pneumatic clamp 46, so that the second idler roller 43 cannot rotate and cannot axially slide. And the third carrier roller 53 can axially slide and rotate, so that the product to be detected can be supported and only vertically upward supporting force can be provided for the product to be detected. The products to be measured are supported by the second carrier rollers 43 and the third carrier rollers 53, so that the products to be measured can be in a free bending state with equal height at two ends before straightness measurement, and the self weight or the original shape of the products to be measured is prevented from being changed by clamping.
After the product to be detected enters the material supporting component and floating support is completed, linearity measurement can be carried out, the longitudinal sliding assembly 71 starts to move from one end of the longitudinal guide rail 61, the electromagnet 76 is electrified to enable the sliding support 73 to ascend, when the sliding support 73 moves to the position right above the product to be detected, the electromagnet 76 is powered off, the contact plate 731 is in contact with the upper surface of the product to be detected under the action of gravity, along with the movement of the longitudinal sliding assembly 71, the distance between the sensor mounting plate 733 and the auxiliary support 74 is detected in real time by the first distance sensor 75, the distance can be directly converted into the linearity of the elevator guide rail in the Y direction, the linearity of the elevator guide rail in the X direction is detected in real time by the second distance sensor 77, and comprehensive linearity detection of the elevator guide rail can be achieved through fitting of the straightness in the.
In the above measurement process, since the product to be measured is not necessarily parallel to the longitudinal guide rail 61 in the transverse direction (X direction in fig. 1), the distance difference between the two ends of the product to be measured needs to be corrected, for example, when the distance data of one end of the elevator guide rail detected by the second distance sensor 77 is 8mm and the distance data of the other end is 20mm, the elevator guide rail should use the connection line of two points at 8mm and 20mm corresponding to the movement locus of the second distance sensor 77 in the horizontal direction as a reference line, so that the transverse error caused by the non-parallelism of the product to be measured and the longitudinal guide rail 61 can be removed. And adopt sliding bracket 73 can increase the measurement width of distance sensor 75, when the product that awaits measuring is not parallel with longitudinal rail 61, still can cover whole guide rail completely, only needs a sensor can accomplish the measurement of this direction straightness accuracy. In the vertical direction, the two ends are in a state of equal height, and the error of the straightness does not cause the second distance sensor 77 to be staggered with the detection part, so the elevator guide rail is always in the measurement range of the second distance sensor 77.
Compared with the prior art, the embodiment can simultaneously measure the straightness of the elevator guide rail in two directions, and can realize the fitting of the straightness in two directions by the method in the prior art.
The material supporting component can ensure that the product to be measured is in a horizontal and longitudinal free deformation state under the condition that the heights of the two ends of the product to be measured are equal, and the influence of the product to be measured on the measurement result due to the self-weight deformation is avoided.
The conveyer 1 of this embodiment, rise material device 2, material feeding unit 3 can provide the relatively high feeding system of degree of automation for the measurement of product, guarantee that the measurement process is high-efficient to go on smoothly.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
