Description

Technical Field

[0001] This invention relates to the field of tooling technology for processing top covers, specifically a special tooling for processing top covers. Background Technology

[0002] The diesel engine top cover is a component located on top of the diesel engine. Its main function is to protect the internal structure of the engine and prevent dust and foreign objects from entering. As a part with a complex shape, high hardness, and high precision requirements, the machining process of the top cover faces many challenges. Existing machining tooling often suffers from insufficient limit performance and low positioning accuracy. This leads to the need for repeated zero-position calibration during the machining process, which not only prolongs the machining cycle but also increases the complexity of operation. At the same time, the cumbersome pressing process and human interference make it difficult to consistently control product quality.

[0003] Therefore, there is an urgent need for a special tooling for processing the top cover. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, the present invention provides a special tooling for processing top covers to solve the problems of insufficient limiting performance and low positioning accuracy. This leads to the need for repeated zero-position calibration during the processing, which not only prolongs the processing cycle but also increases the complexity of operation. At the same time, the cumbersome pressing process and human interference also make it difficult to control the product quality stably.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a special tooling for processing a top cover, comprising: a base plate, a pad being fitted on the top of the base plate, a positioning post being fitted on the top of the base plate, adjusting pads being fitted at both ends of the top of the base plate, studs being fitted at both ends of the top of the base plate, a pressure plate being fitted between the adjusting pad and the stud, a nut being fitted on the outside of the stud, a positioning pin being fitted on the top of the pad, and screws with washers being fitted at the four corners of the top of the pad.

[0008] Preferably, both ends of the positioning pin are provided with L-shaped grooves, which can work with the limiting ring and the protrusion to fix the positioning pin.

[0009] Preferably, the positioning pin is externally slidably connected to a limiting ring, and both sides of the limiting ring are connected to protrusions. The protrusions are slidably disposed inside the L-shaped groove, and the limiting ring can slide inside the L-shaped groove. By rotating the positioning pin 90°, the protrusions, the limiting ring, and the L-shaped groove are used to fix the positioning pin.

[0010] Preferably, the pad is a square block with slots at all four corners, and a washer screw is assembled inside the slot, which allows the washer screw to be assembled.

[0011] Preferably, the stud has threads on its exterior, and the stud is threadedly connected to the nut, which allows the stud to be adjusted.

[0012] Preferably, the washered screw includes a bolt, and a washer is fitted onto the outside of the bolt, the washer increasing the fixing effect of the washered screw.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a special tooling for processing top covers, which has the following advantages:

[0015] This specialized tooling for machining top covers utilizes positioning pins, making parts changeover quick and easy, significantly reducing changeover time and improving production efficiency. Secondly, the single-tool, multi-station design allows for easy multi-station machining; changing stations does not require tooling replacement, further enhancing machining efficiency. Simultaneously, the tooling's stable structure and high clamping force maintain high clamping force even for irregularly shaped parts, while maintaining high positioning accuracy reduces machining cycles and operational complexity, stabilizes product quality, and further improves machining quality and product consistency. Overall, it simplifies the assembly and disassembly process, reduces the impact of human factors on product quality, significantly improves overall machining quality, and substantially increases production efficiency by increasing assembly speed.

[0016] This special tooling for processing the top cover has a positioning pin that, when inserted into the pad, can be quickly fixed and restricted inside the pad by rotating 90°, in conjunction with the L-shaped groove, the limiting ring, and the protrusion. This prevents the pad from shaking up and down during use, thereby improving the overall stability of the device. Attached Figure Description

[0024] This invention provides a technical solution; please refer to [link / reference]. Figure 1 and Figure 2 A special tooling for processing top covers includes: a base plate (1) for fixing and installing the tooling, a pad (2) is fitted on the top of the base plate (1), the pad (2) is installed on the base plate (1) to form the basic support structure of the tooling, and a positioning column (3) is fitted on the top of the base plate (1), the positioning column (3) is installed on the base plate (1) for quick positioning when installing parts.

[0025] Adjusting pads (4) are installed at both ends of the top of the base plate (1). The adjusting pads (4) are located on both sides of the tooling and are used to support the pressure plate and fix the parts to be processed. Studs (5) are installed at both ends of the top of the base plate (1) and are installed on the base plate (1) to fix the parts to be processed.

[0026] A pressure plate (6) is assembled between the adjusting pad (4) and the stud (5). The pressure plate (6) is set on the adjusting pad (4) and the stud (5) to fix the part to be processed. A nut (7) is assembled on the outside of the stud (5). The nut (7) is installed on the stud (5) to fix the pressure plate (6). A positioning pin (8) is assembled on the top of the pad (2). The positioning pin (8) is installed on the pad (2) for quick positioning when the part is installed.

[0027] The pad (2) is equipped with washer screws (9) at the four corners of the top. The washer screws (9) are installed on the pad (2) to fix the parts to be processed. The pad (2) is a square block with slots at all four corners. The washer screws (9) are installed inside the slots. The slots can be used to assemble the washer screws (9). The stud (5) is threaded on the outside and is threadedly connected to the nut (7). The nut (7) can adjust the stud (5).

[0028] The washer screw (9) includes a bolt, and a washer is sleeved on the outside of the bolt. The washer increases the fixing effect of the washer screw (9). The positioning post (3) is installed on the base plate (1), which enables the part to be quickly positioned and fixed, thereby improving processing efficiency and accuracy. The positioning pin (8) is installed on the base plate (1), which enables the part to be quickly positioned and fixed, thereby improving processing efficiency and accuracy.

[0029] The adjusting pad (4), stud (5), pressure plate (6), and nut (7) work together to securely fix the parts. The washer screw (9) and pad (2) work together to securely fix the parts.

[0030] Please see Figure 3 and Figure 4 The positioning pin (8) has L-shaped grooves (81) at both ends of its outer surface.
