[0002] With the continuous progress of the automobile industry, the production and assembly requirements for automobile engines and their components are becoming increasingly strict. Especially for key components such as clutches, as a key connecting device between the engine and the transmission system, its performance plays a crucial role in the entire operating system of the automobile.
[0003] The traditional clutch installation adopts a direct assembly form. When the clutch assembly and the engine are docked and assembled, the center is prone to deviation. This deviation in concentricity not only increases the assembly difficulty and reduces the assembly efficiency, but also causes a series of assembly abnormal problems during subsequent use. For example, it directly affects the smoothness of gear shifting, power transmission efficiency, and the reliability of the whole vehicle, and even leads to safety accidents during vehicle driving. Therefore, designing a simple, new and high-quality three-jaw guiding tooling for an engine clutch is of great significance for ensuring the correct assembly of the clutch, improving the assembly efficiency, and guaranteeing the overall performance of the automobile.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] The present invention will be described in detail below with reference to the accompanying drawings.
[0026] Refer to Figures 1 - 4 , an engine clutch three-jaw guiding tooling, comprising:
[0027] A tooling plate 1, including a main body 101. A first mounting hole 1011 is opened at the center of the main body 101. Three claw portions 102 are evenly distributed around the first mounting hole 1011 in the circumferential direction of the main body 101. Second mounting holes 1021 are opened at the ends of the three claw portions 102;
[0028] A tooling handle 2. After passing through the first mounting hole 1011, the tooling handle 2 is fixedly connected to the tooling plate 1. A guiding section 201 that is in clearance fit with the engine flywheel bearing is provided at the head of the tooling handle 2;
[0029] Tooling pin sleeves 3. After passing through the three second mounting holes 1021 respectively, the three tooling pin sleeves 3 are fixedly connected to the tooling plate 1. The inner cavity of the tooling pin sleeve 3 is in clearance fit with the clutch positioning shaft.
[0030] S1, Assemble the three-jaw guiding tooling: Fix the tooling handle 2 and the three tooling pin sleeves 3 to the tooling plate 1 by appropriate fixing methods to complete the assembly;
[0031] S2, Pre-install the clutch assembly: Use the 6 clutch bolts to pre-install the clutch assembly onto the engine flywheel assembly, ensuring the correct alignment and initial fixation of the clutch assembly and flywheel assembly.
[0032] S3, use the three-claw guide tool: insert the head of the tool handle 2 of the three-claw guide tool into the engine flywheel bearing, and then align the tool pin sleeve 3 with and insert it into the clutch positioning shaft. The clutch assembly and the engine flywheel are relatively supported and positioned by the three-claw guide tool to ensure that the clutch assembly can maintain accurate alignment with the flywheel assembly during installation;
[0033] S4: Tighten the clutch bolts: Use tools such as an electric tightening gun to gradually tighten the clutch bolts until the clutch assembly and the flywheel assembly are completely fixed to complete the final assembly of the clutch assembly.
[0034] Compared with the traditional direct assembly method, the three-claw guide tooling can provide precise guidance to ensure that the clutch assembly can be quickly and accurately positioned on the flywheel assembly during installation or maintenance, thereby improving assembly efficiency and precision, enhancing assembly safety and ensuring assembly quality, and providing strong protection for the safety and reliability of the vehicle.
[0035] Additionally, an inner chamfer 301 is provided at the end of the tooling pin sleeve 3, and an outer chamfer 2011 is provided at the end of the guide section 201. The design of the outer chamfer 2011 makes it easier for the guide section 201 of the tooling handle 2 to extend into the flywheel bearing, and the design of the inner chamfer 301 makes it easier for the tooling pin sleeve 3 to be inserted into the clutch positioning shaft, thereby reducing the difficulty and time during assembly.
[0036] A gripping section 202 is provided at the tail of the tooling handle 2, and a mesh structure is provided on the surface of the gripping section 202. The design of the gripping section 202 is ergonomic, increases the gripping force, and reduces the risk of the tooling handle 2 slipping, so as to ensure that the operator can easily and accurately control the movement and positioning of the tooling, thereby improving the accuracy and efficiency of assembly or maintenance work.
[0037] The three claws 102 are all provided with weight-reducing holes 1022 that penetrate through the thickness direction. On the one hand, the overall weight of the tooling is reduced while ensuring the strength and rigidity of the tooling, making the operation easier. On the other hand, it can be avoided according to the actual assembly situation to avoid affecting the assembly of other parts.
[0038] The tooling handle 2 and the tooling plate 1 are fixed by welding, which ensures a firm connection between the tooling handle 2 and the tooling plate 1, thereby improving the stability and durability of the entire tooling.
[0039] The tooling pin sleeve 3 and the tooling plate 1 are fixed by fasteners. The fasteners include fastening nuts 4 and spring washers, ensuring a firm connection between the tooling pin sleeve 3 and the tooling plate 1, and thus enabling the precise positioning of the tooling pin sleeve 3 in the three-jaw guiding tooling.
[0040] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
