Description

Technical Field

[0001] This invention relates to the field of engine assembly technology, and in particular to a device for fixing an engine crankcase to an assembly vehicle. Background Technology

[0002] Due to development needs, a new type of engine requires production. However, due to the engine's unique design, existing equipment cannot be used to place its crankcase on existing assembly vehicles. Furthermore, the engine's irregular shape means it remains eccentric throughout the assembly process. As more components are added, the weight increases, increasing the risk of the engine becoming unbalanced, tipping over, and falling, potentially causing damage and injury to operators. This not only results in low production efficiency and compromised product quality but also poses significant safety hazards. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device for fixing an engine crankcase to an assembly vehicle, thereby enabling the placement and fixing of a new type of engine crankcase on an existing assembly vehicle and preventing the engine from becoming unbalanced, tipping over, or falling off during the assembly process.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A device for securing an engine crankcase to an assembly vehicle is disclosed. The device comprises two identical left and right parts, each including a support leg, a support leg seat mounted on the lower part of the support leg, a support leg wheel fitted onto the outside of the support leg seat, and a hook. The support leg wheel is fixed to the outside of the support leg seat with screws. When using the device, first, high-strength bolts are used to fix the support leg to the corresponding position on the engine crankcase. Then, the groove of the support leg wheel is placed into a groove on the assembly vehicle to limit the movement of the entire device. Finally, the upper part of the hook is inserted into a fixing hole on the support leg, and the lower part of the hook is hooked to the corresponding position on the assembly vehicle, and the hook is tightened using washers and nuts. When it is necessary to manually rotate the engine 180 degrees, simply remove the hook, washers, and nuts, and after the engine is rotated, reinstall the hook, washers, and nuts in the corresponding positions.

[0006] A further improvement of the technical solution of the present invention is as follows: the support frame includes a first base plate and a second base plate, and two parallel first reinforcing ribs are provided between the first base plate and the second base plate; a first perforated square steel plate is provided on each side of the lower end of the second base plate, and a third reinforcing rib is provided on the inner side of each of the two first perforated square steel plates; a second reinforcing rib is provided between the two third reinforcing ribs and the bottom end of the second base plate; a first hook fixing hole for inserting a hook is also provided at one end of the second base plate; a second perforated square steel plate is also provided parallel to the lower part of one end of the second base plate with the first hook fixing hole; and a second hook fixing hole is provided on the second perforated square steel plate.

[0007] A further improvement of the technical solution of the present invention is that: the first base plate is a right-angled trapezoidal perforated steel plate, which is provided with a number of bolt holes for high-strength bolts to pass through and a first weight-reducing hole.

[0008] A further improvement of the technical solution of the present invention is that: the second base plate is a T-shaped perforated steel plate; it is provided with a first hook fixing hole and a second weight reduction hole.

[0009] A further improvement of the technical solution of the present invention is that the first reinforcing rib plate is a right-angled isosceles triangle plate.

[0010] A further improvement of the technical solution of the present invention is that the second reinforcing plate is a rectangular plate.

[0011] A further improvement of the technical solution of the present invention is that the third reinforcing rib is a right-angled trapezoidal plate.

[0012] A further improvement of the technical solution of the present invention is that: the front part of the outrigger seat is a small cylinder with a chamfer, and the rear part is a large cylinder with a blind hole in the center; the small cylinder is inserted into the mounting hole at the bottom of the outrigger frame; the large cylinder is fitted with an outrigger wheel, and screws are installed in the blind hole.

[0013] A further improvement of the technical solution of the present invention is that the support leg wheel is a wheel-shaped structure with grooves and a stepped through hole in the center.

[0014] A further improvement of the technical solution of the present invention is that the hook has an L-shaped structure, with the upper part being a straight rod that can be inserted into the fixing hole on the support leg, and the lower part being a straight hook with a reinforcing rib.

[0015] The technological advancements achieved by this invention due to the adoption of the above technical solutions are as follows:

[0016] 1. In the design process of this invention, the special features of a new type of engine and the irregular characteristics of the engine as a whole were fully considered, and the crankcase of the new type of engine was placed and fixed on the existing assembly vehicle to prevent the engine from becoming unbalanced, overturning and falling off during the assembly process.

[0017] 2. This invention enables the crankcase of a new type of engine to be fixed on the assembly vehicle even after being manually rotated 180 degrees, thereby reducing production safety hazards and ensuring product quality and production efficiency.

[0018] 3. The present invention fixes the engine crankcase to the existing assembly vehicle, so there is no need to redesign and produce a new assembly vehicle suitable for this engine, thus reducing production costs and saving resources.

[0019] 4. This invention utilizes a simple geometric structure to meet the placement requirements of a new type of engine. It cleverly uses a hook structure to secure the engine to the existing assembly vehicle, preventing the engine from tipping over and falling during assembly due to eccentricity. It also meets the requirement that the engine must still be fixed in place after being tipped over, thereby improving production efficiency, saving resources, and reducing production costs.

[0039] This prevents the engine from sliding forward, backward, left, or right during assembly, which could lead to dangerous situations.

[0040] Furthermore, such as Figure 3-9 As shown, the support frame 1 includes a first base plate 11 and a second base plate 12. Two parallel first reinforcing ribs 13 are provided between the first base plate 11 and the second base plate 12. A first perforated square steel plate 14 is provided on each side of the lower end of the second base plate 12. A third reinforcing rib 17 is provided on the inner side of each of the two first perforated square steel plates 14. A second reinforcing rib 16 is provided between the two third reinforcing ribs 17 and the bottom end of the second base plate 12. A first hook fixing hole 121 for inserting hooks 5 is also provided at one end of the second base plate 12. A second perforated square steel plate 15 is also provided parallel to the lower part of one end of the second base plate 12 with the first hook fixing hole 121. A second hook fixing hole 151 is provided on the second perforated square steel plate 15.

[0041] Furthermore, such as Figure 4 , 5 As shown in Figure 8, the first base plate 11 is a right-angled trapezoidal perforated steel plate, with several bolt holes for high-strength bolts to pass through and a first weight-reducing hole. The first base plate is fixedly installed at the corresponding position of the engine crankcase.

[0042] Furthermore, such as Figure 3 , 4 As shown in Figures 9 and 1, the second base plate 12 is a T-shaped perforated steel plate; it is provided with a first hook fixing hole 121 and a second weight reduction hole.

[0043] Furthermore, such as Figure 3 As shown, the first reinforcing rib plate 13 is a right-angled isosceles triangle plate.

[0044] Furthermore, such as Figure 3, 4 As shown in Figures 8 and 9, the second reinforcing plate 16 is a rectangular plate.

[0045] Furthermore, such as Figure 1 , 3 As shown in Figures 4 and 5, the third reinforcing rib plate 17 is a right-angled trapezoidal plate.

[0046] Furthermore, such as Figure 1 , 10 As shown, the front part of the outrigger 2 is a small cylinder with a chamfer, and the rear part is a large cylinder with a blind hole in the center. The small cylinder is inserted into the mounting hole at the bottom of the outrigger frame 1 (the hole in the first perforated square steel plate 14). The outrigger wheel 4 is fitted onto the outside of the large cylinder, and the screw 3 is installed in the blind hole. The blind hole is provided with a thread that matches the screw.

[0047] Furthermore, such as Figure 1 , 11 As shown, the outrigger wheel 4 is a wheel-shaped structure with grooves and a stepped through hole in the center. The outrigger seat 2 and the screw 3 are inserted into the stepped through hole.

[0048] Furthermore, such as Figure 2 , 12 As shown, the hook 5 has an L-shaped structure, with the upper part being a straight rod that can be inserted into the fixing hole on the support leg 1, and the lower part being a straight hook with a reinforcing rib plate.

[0049] How to use:

[0050] like Figure 13 , 14 As shown in the figure, 8 is a simplified engine model and 9 is a simplified assembly vehicle model.

[0051] The outrigger seat 2 is pressed into the corresponding mounting hole (the hole in the first perforated square steel plate 14) of the outrigger frame 1 using an interference fit method. The outrigger wheel 4 is then positioned... Figure 1 The middle part is fitted onto the support leg 2 and secured with screws 3.

[0052] This device is divided into left and right parts. When using this device, first use high-strength bolts to fix the first base plate 11 on the outrigger bracket 1 to the corresponding position on the engine crankcase. Then, place the groove of the outrigger wheel 4 into the groove of the assembly vehicle to limit the entire device. Finally, insert the upper part of the hook 5 into the corresponding first hook fixing hole 121 and second hook fixing hole 151 on the outrigger bracket 1, and hook the lower part of the hook 5 onto the assembly vehicle (e.g., ...). Figure 13 , 14 After placing the simplified assembly vehicle model 9) in the corresponding positions as shown, use washers 6 and nuts 7 to tighten and secure it, as shown. Figure 13As shown. Depending on assembly requirements, when the engine needs to be manually rotated 180 degrees, simply remove hook 5, washer 6, and nut 7.
