Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an adaptive positioning mandrel for stamping automotive parts. Background Technology

[0002] Automotive parts are the various unit components that make up a car and the consumable materials that serve the car. They include core components such as engines, transmission systems, braking systems, and electrical systems, as well as accessories such as interior and exterior trim. When stamping automotive parts, an adaptive positioning mandrel is needed. An adaptive positioning mandrel is a positioning tooling used in the field of machining. It can adjust its structure to adapt to workpieces of different sizes to achieve precise positioning. It is often used in stamping, wheel hub processing and other scenarios.

[0003] To address this, patent publication CN211639489U discloses a cylindrical grinding tapered positioning mandrel. This mandrel includes a mandrel with a tapered (typically a standard 60° taper angle) tail end and a threaded section at the front. A tapered plug is fitted onto the mandrel, and a nut is screwed into the threaded section to lock the workpiece in place. In use, this cylindrical grinding tapered positioning mandrel utilizes the workpiece's own structure. The chamfered openings of the inner holes at both ends match the taper of the plug and tail sleeve. It directly utilizes the through-hole characteristic of the workpiece's inner hole, allowing the positioning mandrel to pass through the hollow portion of the inner hole. This transforms the process reference into the tapered holes at both ends, facilitating machining, reducing part control costs and processing difficulty, simplifying assembly and disassembly, and effectively utilizing the workpiece's own structure.

[0004] The aforementioned external cylindrical grinding taper positioning mandrel is easy to machine, can reduce part control costs and machining difficulty, and makes the disassembly and assembly process simpler, effectively utilizing the part's own structure. However, in use, the shaft cannot adapt to different situations, and the length of the shaft is difficult to adapt to different situations. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive positioning mandrel for stamping automotive parts, in order to solve the defect of existing adaptive positioning mandrels for stamping automotive parts that are difficult to adjust the height of the shaft.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adaptive positioning mandrel for stamping automotive parts, including a locking block;

[0007] The locking block has a groove inside, a positioning block is installed at the bottom of the locking block, and a connecting block is installed at the bottom of the positioning block.

[0008] The bottom end of the connecting block is equipped with a first shaft, and the bottom end of the first shaft is equipped with a second shaft, and the bottom end of the second shaft is equipped with a shaft head.

[0009] The first shaft body has an internal telescopic structure, which includes a movable groove disposed inside the first shaft body, and a threaded rod is installed inside the movable groove.

[0010] In use, the second shaft can rotate. The threaded groove and threaded rod inside the second shaft form a threaded connection. Rotating the second shaft can drive it to rise and fall. Rotating the second shaft adjusts the overall length of the shaft, allowing it to adapt to different situations. The reinforcing ribs can be made of steel to strengthen the structural strength of the shaft head.

[0011] Furthermore, the outer side of the shaft head is provided with anti-slip grooves, and the anti-slip grooves are arranged at equal intervals on the outer side of the shaft head, which can increase the friction of the shaft head.

[0012] Furthermore, the shaft head has an internal reinforcing structure, which includes a wear-resistant layer disposed inside the shaft head and an isolation layer disposed on the inner side of the wear-resistant layer. The reinforcing structure can enhance the structural strength of the shaft head.

[0013] Furthermore, reinforcing ribs are installed on the outer side of the isolation layer, and the reinforcing ribs are arranged at equal intervals on the outer side of the isolation layer, which can enhance the structural strength of the shaft head.

[0014] Furthermore, the threaded rod has a threaded groove on its outer side, a fixing block is installed at the bottom end of the first shaft, and a fixing screw is installed on the outer side of the fixing block. The telescopic structure can adjust the length of the shaft.

[0015] Furthermore, the outer sidewall of the fixing screw is uniformly provided with external threads, and the inner sidewall of the fixing block is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the fixing block are threadedly connected, and the fixing screw can fix the second shaft.

[0016] Furthermore, the locking block is equipped with a disassembly and assembly structure on both sides. The disassembly and assembly structure includes grooves on both sides of the locking block, and nuts are installed inside the grooves. The nuts have rotating grooves inside, and a mounting screw is installed on one side of the nut. The disassembly and assembly structure can fix the object.

[0017] The adaptive positioning mandrel for stamping automotive parts provided by this utility model has the following advantages: during use, the overall length of the shaft can be adjusted by the telescopic structure, the structural strength of the shaft head can be strengthened by the reinforcing structure, and the objects can be connected by the disassembly and assembly structure.

[0018] By installing a second shaft at the bottom of the first shaft, the first and second shafts form a sliding structure. The second shaft can slide inside the moving groove inside the first shaft. The second shaft can rotate. The threaded groove and threaded rod inside the second shaft form a threaded connection. Rotating the second shaft can drive the second shaft to rise and fall. Rotating the second shaft adjusts the overall length of the shaft, allowing the shaft to adapt to different situations. When it is necessary to fix the second shaft, the fixing screws can be tightened to fix the second shaft. This achieves the purpose of making it easy to adjust the shaft height of the self-adaptive positioning mandrel used for stamping automotive parts.

[0019] By incorporating a wear-resistant layer inside the shaft head, and reinforcing ribs arranged at equal intervals within the wear-resistant layer and the isolation layer, which can be made of steel, the structural strength of the shaft head can be enhanced, preventing damage to the shaft head. This achieves the purpose of strengthening the shaft head of the self-adaptive positioning mandrel used in automotive parts stamping. Attached Figure Description
