[0002] In the fields of industrial automation and precision manufacturing, positioning detection tooling jigs are key tools to ensure product quality and processing accuracy. Previously, after the characters were laser-engraved on the product, the inspectors needed to use a 2D detector to confirm whether there was any deviation in the position, which was very inconvenient and affected the work efficiency of the inspectors. Therefore, there is an urgent need for a positioning detection tooling jig to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a positioning detection tooling jig to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A positioning detection tooling jig, including a bottom plate, a workpiece to be measured, a detection piece, and a bracket. A placement groove is opened at the top of the bottom plate. The four sides of the bottom end of the workpiece to be measured are closely attached to the inner wall of the placement groove. The workpiece to be measured is provided with a character to be inspected one and a character to be inspected two. The detection piece is used to detect whether there is any deviation in the positions of the character to be inspected one and the character to be inspected two. The bracket is connected to one side of the bottom plate, and a lifting mechanism for controlling the detection piece to move towards or away from the bottom plate is provided on the bracket.

[0005] Preferably, the lifting mechanism includes a screw rod, a turning handle, a support column, and a sliding plate. One end of the screw rod is threadedly connected to the top of the bracket, and one end of the screw rod penetrates through the top of the bracket. The turning handle is connected to the top of the screw rod. The other end of the screw rod is rotatably connected to the bottom of the bracket. The support column is installed between the opposite ends of the bracket. The sliding plate is connected to one side of the detection piece.

Detailed Embodiment

[0015] In order to make the implementation means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings. In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection or a mechanical connection, and it can also be an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and the internal communication of two components can be achieved.

[0016] Embodiment 1

[0017] As Figure 1-2A positioning and detection tooling fixture as shown includes a bottom plate 1, a workpiece to be measured 2, a detection piece 5, and a bracket 13. A placement groove 14 is formed at the top of the bottom plate 1. The four sides of the bottom end of the workpiece to be measured 2 are closely attached to the inner wall of the placement groove 14. When the workpiece to be measured 2 is placed in the placement groove 14, the position of the workpiece to be measured 2 will be fixed and will not shake around. An inspection character one 3 and an inspection character two 4 are installed on the workpiece to be measured 2. The detection piece 5 is used to detect whether there is an offset in the positions of the inspection character one 3 and the inspection character two 4. The bracket 13 is connected to one side of the bottom plate 1, and a lifting mechanism for controlling the movement of the detection piece 5 towards or away from the bottom plate 1 is provided on the bracket 13. The bracket 13 is in a U-shaped form, and the lifting mechanism is installed between the corresponding two ends of the bracket 13.

[0018] In this embodiment, the lifting mechanism includes a screw rod 9, a turning handle 10, support columns 11, and a sliding plate 12. One end of the screw rod 9 is threadedly connected to the top of the bracket 13, and one end of the screw rod 9 penetrates through the top of the bracket 13. The turning handle 10 is connected to the top of the screw rod 9. The other end of the screw rod 9 is rotatably connected to the bottom of the bracket 13. There are two support columns 11, and both of the two support columns 11 are installed between the opposite ends of the bracket 13. The two support columns 11 are respectively installed on both sides of the screw rod 9. The sliding plate 12 is connected to one side of the detection piece 5, and the sliding plate 12 is threadedly connected to the screw rod 9. Both ends of the sliding plate 12 are slidably connected to the support columns 11. The support columns 11 limit the two ends of the sliding plate 12 to prevent the sliding plate 12 from shaking left and right during sliding. During detection, after the workpiece to be measured 2 is placed on the bottom plate 1, the sliding plate 12 is driven to move downward along the screw rod 9 by rotating the turning handle 10, driving the detection piece 5 to move towards the bottom plate 1. When the bottom end of the detection piece 5 is in contact with the top of the bottom plate 1, it means that there is no offset in the inspection character one 3 and the inspection character two 4 on the workpiece to be measured 2, otherwise there is an offset. The lifting mechanism has a simple structure and is easy to operate. When in use, the workpiece to be measured 2 is not easy to slide, which can effectively improve the detection speed.

[0019] Embodiment 2

[0020] On the basis of Embodiment 1, the further improvement lies in that, as Figure 3A positioning and detection fixture as shown. A transparent cover plate 6 is installed on the top of the detection piece 5. A detection groove 7 is provided on the transparent cover plate 6. A detection hole 8 is provided on the top of the detection piece 5. A clamping groove 15 is provided on the bottom of the detection piece 5. The inner wall of the detection groove 7 is closely attached to the outer wall of the character to be detected 1 3. The detection hole 8 is arranged according to the shape of the outer wall of the character to be detected 2 4. The inner wall of the clamping groove 15 is closely attached to the outer wall of the piece to be measured 2. When the detection piece 5 contacts the piece to be measured 2, if the character to be detected 1 3 and the character to be detected 2 4 do not shift, the outer wall of the character to be detected 1 3 just closely adheres to the inner wall of the detection groove 6, and the character to be detected 2 4 can just pass through the detection hole 8. Otherwise, it means that the character to be detected 1 3 and the character to be detected 2 4 have shifted. Through the transparent cover plate 6, the fitting condition between the detection groove 6 and the character to be detected 1 3 can be observed. If it is found that they are not closely fitted, it means that the character to be detected 1 3 has shifted. By observing the state of the character to be detected 2 4 in the detection hole 8, if the character to be detected 2 4 cannot pass through the detection hole 8 and is blocked outside the detection hole 8, it means that the character to be detected 2 4 has shifted. If both situations occur simultaneously, it means that both the character to be detected 1 3 and the character to be detected 2 4 have shifted. By providing the detection groove 6, the transparent cover plate 7 and the detection hole 8, the states of the character to be detected 1 3 and the character to be detected 2 4 can be clearly observed, whether there is a shift can be quickly obtained, and the detection of the character to be measured label 1 3 and the character to be measured label 2 4 is more accurate.

[0021] The technological process and working principle of the present utility model are as follows: When performing detection, first place the piece to be measured 2 in the placement groove 14 on the top of the bottom plate 1. The bottom end of the piece to be measured 2 is fixed by the placement groove 14. Then rotate the turning handle 10 to make the screw rod 9 rotate, driving the sliding plate 12 to move downward along the outer wall of the screw rod 9, reducing the height of the detection piece 5, and making the clamping groove 15 in the detection piece 5 gradually contact the outer wall of the piece to be measured 2. If the character to be detected 1 3 and the character to be detected 2 4 do not shift, the outer wall of the character to be detected 1 3 just closely adheres to the inner wall of the detection groove 6, and the character to be detected 2 4 can just pass through the detection hole 8. Otherwise, it means that the character to be detected 1 3 and the character to be detected 2 4 have shifted. Through the transparent cover plate 6, the fitting condition between the detection groove 6 and the character to be detected 1 3 can be observed. If it is found that they are not closely fitted, it means that the character to be detected 1 3 has shifted. By observing the state of the character to be detected 2 4 in the detection hole 8, if the character to be detected 2 4 cannot pass through the detection hole 8 and is blocked outside the detection hole 8, it means that the character to be detected 2 4 has shifted. This makes the detection process more convenient, and can quickly obtain the detection result feedback, having the effects of being easy to operate and improving the detection rate.

[0022] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
