DETAILED DESCRIPTION

[0026] In order to further understand the content, features and functions of the utility model, the following embodiments are given, together with the attached Figures 1 to 7 The detailed instructions are as follows.

[0027] like Figures 1 to 7 As shown, this embodiment provides a combined support fixture for main engine assembly operation. In this embodiment, the number of combined support fixtures 5 is four in total, wherein the main engine 3 includes an engine 31 located on the left and a generator 32 located on the right. The purpose of the combined support fixture 5 proposed in the utility model is to achieve efficient assembly of the engine 31 and the generator 32. Two of the combined support fixtures 5 are arranged on both sides of the engine 31, and the other two are arranged on both sides of the generator 32. The ends of the engine 31 and the generator 32 are both provided with connecting arms 33. A single combined support fixture is arranged between the connecting arm 33 and the frame 1, and the connecting arm 33 is connected to the frame 1 through the connecting seat 2. One end of the connecting seat 2 is provided with a pin shaft hole 21 for placing a pin shaft 4, and the other end is arranged on the frame 1. The pin shaft 4 is used to connect the connecting arm 33 and the connecting seat 2.

[0028] The combined support tool 5 includes a profiling block 51 and a support member 52 connected to each other; the profiling block 51 is provided with a first space 61 for accommodating the connection seat 2 and a second space 62 for accommodating the support member 52 .

[0029] The utility model provides a combined supporting tool, which includes a contour block and a supporting member. The supporting member plays a role in accurately positioning the connecting arm and protecting the connecting arm. The supporting member is provided to lift and position the connecting arm. The supporting member can be used to quickly align the pin hole and insert the pin. There is no need for workers to repeatedly adjust the lifting mechanism to align the pin hole. The operation of adjusting the lifting height and assembling bolt fasteners in a suspended state in the prior art is optimized to the installation of bolt fasteners in a dropped and fixed posture, which greatly reduces the difficulty of the operation and improves the operation efficiency.

[0030] In this embodiment, Figures 2 to 4The figure shows a schematic diagram of the structure of the combined support tooling located at the engine 31 , wherein the profiling block 51 includes two sub-profiling blocks 511 arranged in parallel, the first space 61 is opened on a single sub-profiling block 511 , and the second space 62 is formed between the two sub-profiling blocks 511 .

[0031] In this embodiment, Figure 6 As shown, three threaded through holes 53 are formed on the sub-profiling block 511 and the support member 52 , and the sub-profiling block 511 and the support member 52 are connected by three bolt fasteners 54 adapted to the threaded through holes 53 .

[0032] In this embodiment, Figure 7 As shown, a connecting plate 512 for structural reinforcement is fixedly overlapped on the outer surface of the sub-profile block 511, thereby playing a role in structural reinforcement.

[0033] In this embodiment, Figure 4 As shown, a handle 513 for easy grasping is fixedly provided on the outer surface of the sub-profile block 511 to facilitate grasping.

[0034] In this embodiment, the overall shape of the support member 52 is L-shaped, which facilitates the quick placement of the connecting arm 33 and plays a certain limiting role thereon.

[0035] In this embodiment, Figures 5 to 7 The figure shows a schematic diagram of the structure of the combined support fixture 5 located at the generator 32. Different from the combined support fixture 5 located at the engine 31, the first space 61 is a through channel, and the sub-profile block 511 includes two left and right flat plates of different sizes, and the through channel formed therebetween is used to match the shape of the connecting seat 2.

[0036] In this embodiment, the sub-profile block 511 is made of steel, and the support member 52 is made of nylon, which plays a role in protecting the connecting arm 33 .

[0037] In this embodiment, Figure 1 As shown, the end surface of the support member 52 abutting against the connecting arm 33 and the shape of the outer peripheral surface of the connecting arm 33 are adapted to each other, and the shape of the support member 52 is L-shaped as a whole, which limits the position of the engine 31 and the generator 32 on the yz plane, so that it is convenient to limit and fix the L-shaped support member 52. Of course, other numbers can also be used according to the actual size.

[0038] The working process of the combined support of the utility model is as follows: first, grasp the handle 513 and clamp the two sub-profile blocks 511 on the outer edge of the connecting seat 2 from both sides along the x-axis direction, so that the first space 61 just accommodates the connecting seat 2, and then insert the support member 52 and fix the two with multiple bolt fasteners 54, and wait for the engine 31 and the generator 32 to be hoisted into place, and finally make the main engine 3 as a whole completely fall on the tooling in a assembled posture. At this time, the outer peripheral surface of the connecting arm 33 abuts against the inner end surface of the support member 52, and the inner end surface here refers to the surface in contact with the connecting arm 33. The joint of the engine 31 and the generator 32 is assembled, and when the engine 31 and the generator 32 are assembled with the connecting seat 2, the bolt fastener 54 includes bolts and nuts. The bolts and nuts are removed in turn, and the support member 52 and the two sub-profile blocks 511 are taken away, and then the combined support tooling is used to install other main engines that need to be assembled, which is convenient for reuse.

[0039] The utility model described above in the present invention only expresses the implementation method of the utility model embodiment, and cannot be understood as limiting the scope of the utility model patent, nor is it any form of limitation on the structure of the utility model embodiment. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model embodiment, several changes and improvements can be made, which all belong to the protection scope of the utility model embodiment.
