Description

Technical Field

[0001] This utility model relates to the field of inspection tools, and in particular to a dual positioning inspection tool for automotive parts. Background Technology

[0002] In existing automotive parts inspection fixtures, guide sleeves are mostly mounted on a base plate via a flip-support structure. During inspection, after multiple clamps hold the shell-shaped part in place, each guide sleeve must be manually flipped to the inspection position before the fixture can be inserted for inspection. This process is cumbersome, with each guide sleeve flipping and adjusting taking time, and the sequential operation of multiple guide sleeves resulting in low overall inspection efficiency, making it difficult to meet the rapid inspection requirements of mass production. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a dual positioning fixture for automotive parts, which solves the problem that the guide sleeves of traditional fixtures need to be manually flipped one by one.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] A dual positioning inspection fixture for automotive parts includes a base plate, a contouring seat fixed to the top surface of the base plate, and multiple clamps surrounding the contouring seat on the top surface of the base plate. The clamps are used to press shell-shaped parts onto the contouring seat. Multiple guide sleeves are arranged around the contouring seat above it, and the axis of each guide sleeve is perpendicular to a side wall of the contouring seat opposite it. A synchronous opening and closing device is provided on the base plate, which is used to drive all the guide sleeves to expand or close synchronously. The detection end of the inspection tool passes through the guide sleeve and abuts against the outer wall of the shell-shaped part, and the guide sleeves position the inspection tool.

[0006] Optionally, the clamp is a pressure-type quick clamp, and a spline shaft is fixed on the bottom surface of the base plate corresponding to each lead sleeve. The outer wall of the spline shaft is slidably fitted with a spline sleeve. A through groove is opened on the base plate directly opposite the spline shaft. A support bar is fixed on the outer wall of the spline sleeve. The upper end of the support bar extends through the through groove to the top of the base plate and is fixed with the corresponding lead sleeve.

[0007] Optionally, the synchronous opening and closing device includes a support shaft fixed to the bottom surface of the base plate, a reinforcing ring fixed to the bottom surface of the base plate, and the upper end of the support shaft fixed to the inner wall of the reinforcing ring, which improves the stability of the connection between the support shaft and the base plate. Multiple spline shafts are arranged around the support shaft, and the axis of the spline shaft is perpendicular to the axis of the support shaft. A lifting sleeve is slidably sleeved on the outer wall of the support shaft. A push-pull bar is rotatably connected to the outer wall of the lifting sleeve opposite to each spline sleeve. The end of the push-pull bar away from the lifting sleeve is rotatably connected to the outer wall of the opposite spline sleeve. An electric push rod is fixed to the bottom surface of the base plate. The electric push rod is located between two adjacent push-pull bars and is vertically downward. A connecting piece is fixed to the extended end of the electric push rod, and the lifting sleeve is fixed on the connecting piece.

[0008] Compared with the prior art, the advantages of this utility model are as follows:

[0009] This invention incorporates an electric push rod, a lifting sleeve, a push-pull bar, a spline sleeve, and a spline shaft. The electric push rod drives the lifting sleeve to rise and fall, which in turn moves the push-pull bar to slide the spline sleeve along the spline shaft. This allows all the guide sleeves to expand or converge synchronously, eliminating the need for manual flipping of each guide sleeve. After the shell-shaped part is positioned once, the guide sleeves can be automatically positioned a second time, and the secondary positioning of all guide sleeves is performed simultaneously. This simplifies the operation process and improves testing efficiency. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1 to 3This embodiment provides a dual positioning fixture for automotive parts, including a base plate 1. A contouring seat 2 is fixed on the top surface of the base plate 1. The shape of the contouring seat 2 is adapted to the inner wall of the shell-shaped part to be inspected, which can play a preliminary positioning role for the shell-shaped part and ensure the accuracy of the part placement position.

[0016] The top surface of the base plate 1 is provided with three clamps surrounding the contour base 2. In this embodiment, the clamps are pressure-type quick clamps 3. When the pressure-type quick clamps 3 are activated, they can firmly press the shell-shaped part onto the contour base 2, preventing the part from shaking or shifting during the inspection process and ensuring the stability of the inspection. The pressure-type quick clamps 3 are existing and mature technologies, and will not be described in detail here.

[0017] Three guide sleeves 4 are arranged around the top of the profile holder 2, and the axis of each guide sleeve 4 is perpendicular to one side wall of the profile holder 2 opposite it. The guide sleeves 4 are used to guide the inspection tool. When the inspection end of the inspection tool passes through the guide sleeve 4 and abuts against the outer wall of the shell-shaped part, it can ensure the accuracy of the inspection direction and improve the reliability of the inspection data.

[0018] A splined shaft 5 is fixed to the bottom surface of the base plate 1 corresponding to each lead sleeve 4, and a splined sleeve 6 is slidably fitted onto the outer wall of the splined shaft 5. The cooperation between the splined shaft 5 and the splined sleeve 6 guides and limits the movement of the splined sleeve 6, ensuring that the splined sleeve 6 can only slide along the axial direction of the splined shaft 5 and preventing it from deviating. A through groove 7 is provided on the base plate 1 directly opposite the splined shaft 5, and a support bar 8 is fixed to the outer wall of the splined sleeve 6. The upper end of the support bar 8 extends through the through groove 7 to the top of the base plate 1 and is fixed to the corresponding lead sleeve 4. When the splined sleeve 6 slides along the splined shaft 5, it will drive the lead sleeve 4 to move synchronously through the support bar 8, thereby adjusting the position of the lead sleeve 4.

[0019] A reinforcing ring 9 is fixed to the bottom surface of the base plate 1, which enhances the stability of the connection. A support shaft 10 is fixed to the inner wall of the reinforcing ring 9. The support shaft 10 is vertically arranged, and three splined shafts 5 are distributed around the support shaft 10. The axis of the splined shafts 5 is perpendicular to the axis of the support shaft 10. This arrangement makes the force on each component more even and the operation more stable.

[0020] A lifting sleeve 11 is slidably fitted onto the outer wall of the support shaft 10, and the lifting sleeve 11 can slide up and down along the axial direction of the support shaft 10. A push-pull bar 12 is rotatably connected to the outer wall of the lifting sleeve 11 opposite to each spline sleeve 6. The end of the push-pull bar 12 facing away from the lifting sleeve 11 is rotatably connected to the outer wall of the opposite spline sleeve 6. When the lifting sleeve 11 moves up and down, it drives the spline sleeve 6 to slide along the spline shaft 5 through the push-pull bar 12, thereby achieving synchronous movement of the lead sleeve 4.

[0021] An electric push rod 13 is fixed to the bottom surface of the base plate 1. The electric push rod 13 is located between two adjacent push-pull bars 12 and is vertically downward. A connecting piece 14 is fixed to the extended end of the electric push rod 13, and the lifting sleeve 11 is fixed to the connecting piece 14. When the electric push rod 13 is working, the extension and retraction of its extended end will drive the lifting sleeve 11 to rise and fall along the support shaft 10 through the connecting piece 14, thereby driving the entire guide sleeve 4 moving mechanism to operate.

[0022] In the actual testing process, the shell-shaped part is first placed on the contour base 2 for initial positioning. Then, the downward-pressing quick clamp 3 is operated to clamp the part. Next, the electric push rod 13 is activated, which drives the lifting sleeve 11 to rise and fall, thereby driving the push-pull bar 12 to pull the spline sleeve 6 to slide along the spline shaft 5, so that all the lead sleeves 4 expand or converge to the testing position, thereby guiding and positioning the testing tool. Finally, the testing end of the testing tool is passed through the lead sleeve 4 and pressed against the outer wall of the shell-shaped part for testing.

[0023] In summary, compared with traditional technologies, this embodiment eliminates the need for manual flipping of each guide sleeve 4. After the shell-shaped part is positioned initially, the guide sleeve 4 can be automatically positioned a second time, and the secondary positioning of all guide sleeves 4 is performed simultaneously, effectively simplifying the operation process and improving inspection efficiency. Furthermore, the precise coordination of each component ensures the stability of the inspection process and the accuracy of the inspection results.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
