[0027] Please refer to Figures 1 to 3 .

[0028] In a specific embodiment, the straightness inspection tool provided by the specific embodiment of the utility model includes a inspection tool body, on which a straightness inspection groove 2 is obliquely arranged for the product to be inspected to slide freely. Specifically, the angle between the straightness inspection groove 2 and the horizontal plane is an acute angle, and the bottom of the straightness inspection groove 2 provides support for the product to be inspected. The opposite sides of the straightness inspection groove 2 are used to fit with the opposite sides of the product to be inspected. The straightness inspection groove 2 includes a first slide groove 201 and a second slide groove 202 that is isolated from the first slide groove 201 and located below the first slide groove 201. Specifically, the interval between the first slide groove 201 and the second slide groove 202 is preferably less than the length of the product to be inspected along the free sliding direction. Specifically, the first slide groove 201 and the second slide groove 202 can both be rectangular groove bodies.

[0029] The two side walls of the first chute 201 and the two side walls of the second chute 202 are coplanar, that is, the left side wall of the first chute 201 is coplanar with the left side wall of the second chute 202, and the right side wall of the first chute 201 is coplanar with the right side wall of the second chute 202. When the product to be inspected slides from the first chute 201 to the second chute 202, the straightness of the product to be inspected is qualified, otherwise the straightness of the product to be inspected is unqualified.

[0030] Specifically, a straightness inspection groove 2 can be provided on the gauge body, which is used to inspect the straightness of a product to be inspected. In order to improve the inspection efficiency of the straightness gauge, preferably, at least two straightness inspection grooves 2 are provided in sequence along the horizontal direction on the gauge body, and the widths of two adjacent straightness inspection grooves 2 are the same. In order to improve the versatility of the straightness gauge, preferably, the widths of two adjacent straightness inspection grooves 2 are different.

[0031] When the product to be inspected needs to be inspected for straightness, the product to be inspected is placed on the top of the first chute 201, and the product to be inspected slides downward under the action of its own gravity. When the product to be inspected slides to the second chute 202, it means that the interval between the first chute 201 and the second chute 202 does not block the product to be inspected, and the straightness of the product to be inspected is qualified. When the product to be inspected slides downward under the action of its own gravity, the product to be inspected cannot slide to the second chute 202, which means that the interval between the first chute 201 and the second chute 202 blocks the product to be inspected, and the straightness of the product to be inspected is unqualified.

[0032] From the above description, it can be seen that in the straightness inspection tool provided in the specific embodiment of the present application, the staff only needs to place the product to be inspected in the first slide groove 201, and by observing the sliding condition of the product to be inspected, it can be known whether the straightness of the product to be inspected is qualified. The operation is simple and the convenience of straightness inspection is improved.

[0033] In a specific embodiment, three straightness inspection grooves 2 are sequentially arranged on the gauge body along the horizontal direction, and the straightness of the three straightness inspection grooves 2 gradually increases along the horizontal direction. Figure 2 As shown, the straightness inspection grooves 2 are respectively straightness inspection grooves 2a, straightness inspection grooves 2b and straightness inspection grooves 2c. Specifically, the straightness inspection grooves 2 with a straightness of 0.07mm, the straightness inspection grooves 2 with a straightness of 0.065mm and the straightness inspection grooves 2 with a straightness of 0.06mm can be set. At this time, the gauge body has three specifications, namely 0.60mm, 0.065mm and 0.07mm, and the three specifications of the gauge should correspond to the measurement results (correlation) of OMM / CMM, 0.06mm corresponds to the OMM / CMM measurement result of 0.05mm, 0.065mm corresponds to the OMM / CMM measurement result of 0.055mm, and 0.07mm corresponds to the OMM / CMM measurement result of 0.06mm.

[0034] In order to facilitate the sliding of the product to be inspected, preferably, the bottom of the first chute 201 and the bottom of the second chute 202 are coplanar. Of course, in actual use, the bottom of the second chute 202 can be deeper than the bottom of the first chute 201, or the depth of the second chute 202 gradually increases along the sliding direction of the product to be inspected.

[0035] In order to facilitate the support stability of the gauge body, preferably, the straightness gauge also includes a support frame 6, and the gauge body is obliquely installed on the side of the support frame 6. Specifically, the gauge body is detachably and obliquely installed on the side of the support frame 6, or the gauge body is welded or welded to the side of the support frame 6. In order to improve assembly efficiency, preferably, the support frame 6 and the gauge body are integrally formed.

[0036] In order to improve the support stability, preferably, the support frame 6 is provided with at least two triangular fixing frames, and the triangular fixing frames are arranged in sequence along the horizontal direction.

[0037] Further, the straightness gauge also includes a base 4, and the bottom end of the support frame 6 is mounted on the upper surface of the base 4, and the base 4 provides stable support for the support frame 6 and the gauge body. Specifically, the triangular fixing frame is mounted on the base 4 by threaded fasteners.

[0038] In a specific embodiment, the support frame 6 includes a triangular fixing frame, the bottom plate of the triangular fixing frame is fixedly connected to the base 4, and the side plates of the triangular fixing frame are fixedly connected to the inspection fixture body. Specifically, the bottom plate of the triangular fixing frame and the two side plates are connected end to end to form an equilateral triangle.

[0039] A groove 3 is provided on the gauge body to separate the first slide groove 201 and the second slide groove 202. Figure 2 As shown, all straightness inspection grooves 2 correspond to the same groove 3. In this case, the inspection fixture body can be easily processed.

[0040] In another embodiment, if Figure 3 As shown, the straightness inspection grooves 2 correspond to the grooves 3 one by one, and adjacent grooves 3 can be isolated by protrusions 5 arranged on the gauge body.

[0041] In order to reduce the end face damage of the product to be inspected, preferably, the straightness inspection tool further includes an anti-collision elastic stopper 1, which is located below the second slide groove 202 to accommodate the product to be inspected. In order to facilitate the use of the straightness inspection tool, preferably, the anti-collision elastic stopper 1 is fixedly connected to the base 4.

[0042] Specifically, the anti-collision elastic stopper 1 can be a plastic pad or a sponge pad.

[0043] During specific use, the present application places the product to be inspected in the specified straightness inspection groove 2, allowing the product to slide freely and then fall on the anti-collision elastic stopper 1. If the straightness of the product to be inspected is qualified, it will slide freely, and if the straightness is unqualified, it will not slide smoothly.
