Technical Field
[0001] This utility model relates to the field of automotive stamping parts quality inspection technology, specifically, it demonstrates a quick inspection tooling for automotive stamping parts. Background Technology
[0002] In the automotive manufacturing industry, many parts are manufactured using stamping processes. Stamped parts have relatively simple structures, low production costs, and high production efficiency. Before leaving the factory, the finished stamped parts need to be inspected to ensure their quality. For stamped parts with partially curved surfaces, which differ from ordinary, more rigid stamped parts, the curvature of the curved surface also needs to be inspected for compliance. Common inspection fixtures are complex, requiring multiple inspections using different fixtures to determine the quality of stamped parts with partially curved surfaces, hindering the rapid inspection of curved surfaces on stamped parts. Utility Model Content
[0003] The purpose of this invention is to provide a quick inspection fixture for automotive stamping parts, which has a simple and practical structure and high inspection efficiency.
[0004] The technical solution is as follows:
[0005] A quick inspection fixture for automotive stamped parts includes a base and, disposed on the base, an inspection table, a fixture, an arc-shaped inspection plate, and a hole position inspection pin. A sloping profile seat is provided on one side of the upper part of the inspection table, the surface of which is used to place the stamped part to be inspected. The fixture is positioned close to the inspection table to fix the stamped part to be inspected onto the sloping profile seat. The sloping profile seat has a contour seat and an inspection pin hole, corresponding to the arc-shaped structure and inspection hole position on the stamped part to be inspected, respectively. The arc-shaped inspection plate is movably disposed on the sloping profile seat and can move directly opposite the contour seat. The head end of the arc-shaped inspection plate has an arc-shaped semi-groove that matches the outer surface of the arc-shaped structure on the stamped part to be inspected. The hole position inspection pin is inserted into the inspection pin hole after passing through the inspection hole position on the stamped part to be inspected.
[0006] Optionally, the arc-shaped inspection plate is movably inserted into a guide seat, which is disposed on the inclined contour seat, and the arc-shaped inspection plate is perpendicular to the contour seat. During inspection, the operator manually pushes the arc-shaped inspection plate so that the arc-shaped semi-groove at its head end approaches the arc-shaped structure on the contour seat. After inspection, the operator manually pulls the arc-shaped inspection plate away from the stamping part to be inspected.
[0007] The guide seat is equipped with a guide pin whose lower end can penetrate its interior, and a strip-shaped guide groove is provided in the middle of the arc-shaped detection plate. The lower part of the guide pin is located in the guide groove and can slide relative to the guide groove. The reliable sliding cooperation between the guide pin and the guide groove ensures the stability of the arc-shaped detection plate during its movement relative to the guide seat, thus guaranteeing the inspection accuracy of the arc-shaped detection plate.
[0008] Furthermore, a handle is provided at the tail of the arc-shaped detection plate. This allows the operator to push or pull the arc-shaped detection plate using the handle, thereby achieving relative movement with the guide seat.
[0009] Optionally, the fixture includes a column mounted on the base and an elbow clamp located at the top of the column, which secures the stamping to be inspected to the inclined contour seat. Using a standard elbow clamp enables rapid clamping and release of the stamping to be inspected.
[0010] Optionally, the contour seat is embedded in the inclined contour seat, and a gap is left between the bottom surface of the contour seat and the inclined contour seat to facilitate the fitting of the arc-shaped structure on the stamped part to be inspected with the contour seat.
[0011] The top surface of the contour seat is provided with a positioning pin to correspond to a pre-drilled through hole on the stamped part to be inspected. This ensures that the stamped part to be inspected can be accurately placed on the inclined contour seat, guaranteeing the stable progress of the inspection work.
[0012] Optionally, multiple inspection stations are arrayed on the base, each station being equipped with a fixture, an arc-shaped inspection plate, a hole position inspection pin, and a beveled contour seat. This enables the inspection of multiple sets of stamped parts, thereby improving inspection efficiency.
[0013] Compared with the prior art, the advantages of this utility model are as follows: the stamped part to be inspected is accurately placed on the inclined contour seat, the arc-shaped structure on the stamped part is correspondingly fitted to the outer surface of the contour seat, the inspection holes on the stamped part are aligned with the detection pin holes, and then the stamped part is fixed on the inclined contour seat by a clamp; the arc-shaped semi-groove at the end of the arc-shaped detection plate abuts against the arc-shaped structure on the stamped part, and the presence of gaps at the contact points is observed to quickly determine whether the arc-shaped structure is machined to a satisfactory standard; the end of the hole detection pin is inserted into the detection pin hole after passing through the inspection hole on the stamped part. If it can be inserted into the detection pin hole just right, it indicates that the machining position of the inspection hole is qualified; if it cannot be inserted into the detection pin hole smoothly, it indicates that the machining position of the inspection hole is deviated. This utility model has a simple structure, can quickly determine whether the arc-shaped structure and inspection holes on the stamped part are machined to a satisfactory standard, is very convenient to use, and has low cost.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] This utility model provides a quick inspection fixture for automotive stamping parts, used to solve the technical problems mentioned in the background art. For example... Figure 1 and Figure 2 As shown, specifically, it includes a horizontal base 1, and on the base 1: a testing table 2, a clamp 3, an arc-shaped testing plate 4, and a hole position testing pin 5. An inclined contouring seat 6 is inclinedly arranged on one side of the upper part of the testing table 2. The surface of the inclined contouring seat 6 is used to tilt the stamping part to be inspected (for certain considerations, the structure of the stamping part is not shown in this application, but this does not affect other skilled personnel's understanding of the scheme in this application specification), that is, the surface shape of the inclined contouring seat 6 is completely adapted to the shape of the stamping part to be inspected; the clamp 3 is arranged close to the testing table 2, and it can apply a certain pressure to the surface of the stamping part to be inspected to press and fix the stamping part to be inspected onto the inclined contouring seat; the inclined contouring seat 6 has a contour seat 61 and a testing pin hole 62, which respectively correspond to the arc-shaped structure and the testing hole position on the stamping part to be inspected. The contour seat 61 is located below the surface of the inclined contour seat 6, while the detection pin hole 62 is located above the surface of the inclined contour seat 6. The arc-shaped detection plate 4 is movably disposed on one side of the bottom of the inclined contour seat 6 and can move directly in the direction of the contour seat 61. The head end of the arc-shaped detection plate 4 has an arc-shaped semi-groove 41 that matches the outer surface of the arc-shaped structure on the stamping part to be inspected. That is to say, if the stamping part to be inspected is processed into a standard part, the arc-shaped semi-groove 41 on the arc-shaped detection plate 4 can just abut against the arc-shaped structure on the stamping part to be inspected. The hole position detection pin 5 is inserted into the detection pin hole 62 after passing through the inspection hole on the stamping part to be inspected.
[0019] During inspection: The stamped part to be inspected is accurately placed on the inclined contour base 6. The arc-shaped structure on the stamped part is aligned with the outer surface of the contour base 61. The inspection holes on the stamped part are aligned with the detection pin holes 62. Then, the stamped part is fixed on the inclined contour base 6 using the clamp 3. The arc-shaped semi-groove 41 at the end of the arc-shaped detection plate 4 abuts against the arc-shaped structure on the stamped part. By observing whether there is a gap at the contact point, it is quickly determined whether the arc-shaped structure is machined to be qualified. The end of the hole detection pin 5 is inserted into the detection pin hole 62 after passing through the inspection hole on the stamped part. If it can be inserted into the detection pin hole just right, it indicates that the machining position of the inspection hole is qualified. If it cannot be inserted into the detection pin hole smoothly, it indicates that the machining position of the inspection hole is deviated, and the product is unqualified.
[0020] In this embodiment, the arc-shaped detection plate 4 is movably inserted into a guide seat 7, which is located on the bottom side of the inclined contour seat 6. The arc-shaped detection plate 4 is perpendicular to the contour seat 61, meaning that the arc-shaped semi-groove 41 at the head end of the arc-shaped detection plate 4 is vertically aligned with the side of the contour seat 61, thus ensuring accurate correspondence with the arc-shaped structure on the stamping part to be inspected. During inspection, the operator manually pushes the arc-shaped detection plate so that the arc-shaped semi-groove at its head end is close to the arc-shaped structure on the contour seat. After inspection, the operator manually pulls the arc-shaped detection plate away from the stamping part to be inspected.
[0021] Furthermore, a guide pin 71 with its lower end penetrating its internal channel is inserted into the guide seat 7, and a strip-shaped guide groove 42 is provided in the middle of the arc-shaped detection plate 4. The lower part of the guide pin 71 is located in the guide groove 42 and can slide relative to the guide groove 42. The lower part of the guide pin 71 is designed to be exactly the same as the width of the guide groove 42. Through the reliable sliding cooperation between the guide pin and the guide groove, the movement stability of the arc-shaped detection plate is ensured during the movement of the plate relative to the guide seat, thus guaranteeing the inspection accuracy of the arc-shaped detection plate.
[0022] A protruding handle 43 can be provided at the tail of the arc-shaped detection plate 4. This allows the operator to push or pull the arc-shaped detection plate to achieve relative movement with the guide seat.
[0023] In this embodiment, the fixture 3 includes a column 31 mounted on the base 1 and an elbow clamp 32 mounted on the top of the column 31. The elbow clamp 32 applies a certain pressure to the surface of the stamping part to be inspected, thereby pressing and fixing the stamping part to be inspected onto the inclined contour seat 6. The use of a standard elbow clamp enables quick clamping and release of the stamping part to be inspected, making the operation simple.
[0024] In this embodiment, the contour seat 61 is essentially embedded in the inclined contour seat 6, with a gap between the bottom surface of the contour seat 61 and the inclined contour seat 6. This facilitates the fitting of the arc-shaped structure on the stamping part to be inspected with the contour seat, and makes it easier to position the arc-shaped structure on the stamping part to be inspected.
[0025] The top surface of the contour base 61 is provided with a positioning pin 63 to correspond to the reserved through hole on the stamping part to be inspected. This ensures that the stamping part to be inspected can be accurately placed on the inclined contour base, guaranteeing the stable progress of the inspection work.
[0026] In other embodiments, multiple inspection stations 2 can be arrayed on the base 1, each inspection station 2 being equipped with a fixture 3, an arc-shaped inspection plate 4, a hole position inspection pin 5, and an inclined contour seat 6. This enables the inspection of multiple sets of stamped parts, allowing for batch operations and improving inspection efficiency.
[0027] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
