Detailed Embodiments

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments.

[0024] It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0025] In the embodiments, unless otherwise specified, the means used are all conventional means in the art.

[0026] Please refer to Figures 1 - 3 , this application provides an assembly auxiliary connection device for an engine assembly line, including an auxiliary connection component 100. The first threaded sleeve 150 and the second threaded sleeve 160 are threaded on the assembly flat car connecting plate 140, which facilitates removing the first threaded sleeve 150 and the second threaded sleeve 160 from the assembly flat car connecting plate 140. This auxiliary connection device facilitates replacing the first threaded sleeve 150 and the second threaded sleeve 160, providing a better user experience for the user.

[0027] Please refer to Figures 1 - 3 , the auxiliary connection component 100 includes: an engine connecting plate 110, a first adjusting sleeve 120, a first adjusting washer 130, an assembly flat car connecting plate 140, a first threaded sleeve 150, a second threaded sleeve 160, an intermediate connecting plate 170, a second adjusting washer 190, and a second adjusting sleeve 191. The intermediate connecting plate 170 is fixed between the engine connecting plate 110 and the assembly flat car connecting plate 140. The auxiliary connection component 100 further includes a lifting ring 180, and the lifting ring 180 is fixed on the outer wall of the intermediate connecting plate 170. The lifting ring 180 facilitates the crane to lift this connection device beside the engine cylinder block. The auxiliary connection component 100 further includes two groups of reinforcing ribs 192. One group of the reinforcing ribs 192 is fixed between the engine connecting plate 110 and the intermediate connecting plate 170, and the other group of the reinforcing ribs 192 is fixed between the assembly flat car connecting plate 140 and the intermediate connecting plate 170. The reinforcing ribs 192 effectively prevent the engine connecting plate 110 and the assembly flat car connecting plate 140 from deforming. The first adjusting sleeve 120 and the second adjusting sleeve 191 are both threaded on the engine connecting plate 110, and the first adjusting sleeve 120 and the second adjusting sleeve 191 facilitate adjusting the parallelism between the engine and the assembly flat car connecting plate 140.

[0028] The engine connecting plate 110 is provided with a first threaded hole 193. The second adjusting sleeve 191 is threaded into the first threaded hole 193. The first threaded hole 193 facilitates threading the second adjusting sleeve 191 onto the engine connecting plate 110. The first adjusting washer 130 is arranged between the engine connecting plate 110 and the first adjusting sleeve 120. The engine connecting plate 110 is provided with a third threaded hole 197. The first adjusting sleeve 120 is threaded into the third threaded hole 197. The third threaded hole 197 facilitates threading the first adjusting sleeve 120 onto the engine connecting plate 110. The second adjusting washer 190 is arranged between the engine connecting plate 110 and the second adjusting sleeve 191. The first threaded sleeve 150 and the second threaded sleeve 160 are both threaded onto the assembly flatcar connecting plate 140. The assembly flatcar connecting plate 140 is provided with a second threaded hole 194. The second threaded sleeve 160 is threaded into the second threaded hole 194.

[0029] The second threaded hole 194 facilitates threading the second threaded sleeve 160 onto the assembly flatcar connecting plate 140. The assembly flatcar connecting plate 140 is provided with a fourth threaded hole 198. The first threaded sleeve 150 is threaded into the fourth threaded hole 198. The fourth threaded hole 198 facilitates threading the first threaded sleeve 150 onto the assembly flatcar connecting plate 140. There are four fourth threaded holes 198 and one second threaded hole 194. The number of the first threaded sleeves 150 is the same as that of the fourth threaded holes 198, and the number of the second threaded holes 194 is the same as that of the second threaded sleeves 160. The four first threaded sleeves 150 and one second threaded sleeve 160 make the assembly flatcar connecting plate 140 and the assembly flatcar more firmly connected together. The engine connecting plate 110 and the assembly flatcar connecting plate 140 are parallel to each other to ensure the rapid assembly of the engine. The intermediate connecting plate 170 is provided with a first weight-reducing hole 195 and a second weight-reducing hole 199. The first weight-reducing hole 195 and the second weight-reducing hole 199 reduce the weight of the connecting device and save materials. To prevent the first adjusting sleeve 120, the second adjusting sleeve 191, the first threaded sleeve 150, and the second threaded sleeve 160 from being pulled out, these components are arranged in the opposite direction of the force. The engine connecting plate 110 is provided with through holes 1990. Different through holes 1990 are respectively arranged corresponding to the first threaded sleeve 150 and the second threaded sleeve 160. The through holes 1990 facilitate the disassembly and assembly of the first threaded sleeve 150 or the second threaded sleeve 160.

[0030] Specifically, the working principle of the assembly auxiliary connection device of this engine assembly line: During use, the connection device is lifted by a crane through the lifting ring 180, and the connection device is hoisted beside the engine cylinder block. The engine connecting plate 110 is installed on the side screw holes of the cylinder block. The connection device together with the engine cylinder block is hoisted beside the assembly flat car on the assembly line. The assembly flat car connecting plate 140 is connected to the assembly flat car through the first threaded sleeve 150 and the second threaded sleeve 160. The position of the engine connecting plate 110 and the engine is adjusted through the first adjusting sleeve 120, the second adjusting sleeve 191, the first adjusting washer 130 and the second adjusting washer 190 on the engine connecting plate 110. The first adjusting sleeve 120 and the second adjusting sleeve 191 are connected to the engine cylinder sleeve. The five bolts on the assembly flat car are connected to the four first threaded sleeves 150 and one second threaded sleeve 160 on the assembly flat car connecting plate 140. Since both the first threaded sleeve 150 and the second threaded sleeve 160 are threaded onto the assembly flat car connecting plate 140, the depth of the ends of the first threaded sleeve 150 and the second threaded sleeve 160 inside the assembly flat car connecting plate 140 can be controlled, facilitating the adjustment of the position accuracy of the engine on the line. The attitude of the engine on the assembly line can be adjusted to adapt to the equipment on the line. When the threads inside the first threaded sleeve 150 or the second threaded sleeve 160 on the assembly flat car connecting plate 140 are damaged, they can be replaced in time to make it suitable for the equipment on the assembly line, completing the engine assembly. This auxiliary connection device facilitates the replacement of the first threaded sleeve 150 and the second threaded sleeve 160, giving users a better user experience.

[0031] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the invention patent.

[0032] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of this invention patent should be subject to the appended claims.
