Description

Technical Field

[0001] The utility model belongs to the technical field of gearbox assembly tooling, and in particular relates to a gearbox bracket assembly assembly tooling. Background Art

[0002] The gearbox bracket assembly is composed of three parts: suspension flexible shaft, suspension bracket and suspension hanger, which are screwed together. During assembly, the suspension hanger and the suspension flexible shaft must be assembled first, and the nuts must be tightened. Then the assembled sub-assembly must be assembled with the suspension bracket and tightened with nuts.

[0003] The traditional method is to connect the suspension hanger with the locating pin on one side of the suspension flexible shaft during assembly, and then connect the suspension flexible shaft to the suspension bracket through bolts. Since there is only one locating pin, it can only be connected to the suspension bracket at one point, and there is a gap of about 1mm between the bolt hole and the through hole of the suspension bracket at the other point, so there is still a moving gap between the suspension flexible shaft and the suspension bracket. It is difficult to ensure the centering accuracy between the suspension flexible shaft and the suspension bracket by manual positioning by workers alone, resulting in a decrease in positioning accuracy. Similarly, by using the suspension flexible shaft to align the suspension bracket with the locating pin on the other side, the suspension flexible shaft can be easily connected to the suspension bracket. The positioning pin on one side is docked with the suspension hanger, and then connected to the suspension hanger by bolts. Since there is a gap of about 1 mm between the bolt hole of the suspension flexible shaft and the through hole of the suspension hanger, there is still a moving gap between the suspension flexible shaft and the suspension hanger. It is difficult to ensure the centering accuracy by manual centering by workers alone, and it is easy to cause position offset between the suspension flexible shaft and the suspension hanger, resulting in inaccurate positioning. In addition, it is inconvenient to operate power tools during the centering process, and manual tightening increases labor intensity, reduces work efficiency, and has a high return rate for defective products.

Since the first positioning component 2 can realize the positioning of the suspension flexible shaft 15 and the suspension bracket 16, the second positioning component 3 can realize the positioning of the suspension flexible shaft 15, the suspension bracket 16 and the suspension hanger 17, therefore, the workers can free their hands to operate the power tools conveniently, improve labor efficiency and reduce labor intensity.

[0051] Preferably, the first positioning assembly 2 and the second positioning assembly 3 are respectively arranged above the base 1, and the first positioning assembly 2 and the second positioning assembly 3 are separated by a preset distance. After the suspension bracket 16 assembly is installed on the first positioning assembly 2, Figure 3 As shown, the suspension bracket 16 assembly is turned over and placed on the second positioning component 3, and the suspension bracket 16 assembly and the suspension hanger 17 are assembled on the second positioning component 3 to form a gearbox bracket assembly.

[0053] In this implementation mode, the following two different embodiments may be used, but the specific application may not be limited to the structures listed in the embodiments of this application:

[0054] Example 1: Figure 1 and Figure 2 As shown, the first positioning seat 22 includes a positioning plate 222 and a positioning block 221. The positioning plate 222 is connected to the top of the first support 21, and the positioning block 221 is connected to the top of the positioning plate 222. The size of the positioning plate 222 is larger than that of the positioning block 221, in order to reserve space for installing multiple first positioning pins 6. The positioning block 221 is connected to one side of the positioning plate 222 facing the first end 13 of the base, and the first positioning pin 6 is connected to the other side of the positioning plate 222 facing the second end 14 of the base.

[0055] A first positioning groove 4 is formed on one side of the positioning block 221 facing the first end 13 of the base. When in use, the suspension flexible shaft 15 is installed in the first positioning groove 4. The bottom wall of the suspension flexible shaft 15 abuts against the step surface described below, so that the top surface of the suspension flexible shaft 15 protrudes from the first positioning groove 4. Therefore, in order to facilitate the installation of the suspension bracket 16, the suspension bracket 16 needs to be positioned and installed above the suspension flexible shaft 15 and corresponding to the installation position of the suspension flexible shaft 15. Therefore, it is necessary to connect a plurality of first positioning pins 6 to the side of the positioning plate 222 away from the positioning block 221.

[0057] Embodiment 2: The first positioning seat 22 includes a positioning block 221, and the positioning block 221 has a positioning platform protruding from the positioning block 221 in the horizontal direction. The positioning block 221 of the first positioning seat 22 is directly connected to the first support 21, and the positioning block 221 is provided with a positioning platform protruding in the horizontal direction. The purpose of providing the positioning platform is to facilitate the installation of the first positioning pin 6.

[0058] The above two embodiments are arranged in this way so that the first positioning seat 22 can be a detachable structure or a non-detachable structure, which is convenient for making more choices according to needs in actual applications.

[0059] As a preferred embodiment, the suspension bracket 16 has a fixed end and a connecting end inclined to the fixed end; the positioning block 221 has a positioning end parallel to the connecting end of the suspension bracket 16, so that the suspension flexible shaft 15 installed on the positioning end is parallel to the connecting end of the suspension bracket 16 for assembly.

[0066] As a preferred embodiment, positioning steps 18 are formed on both side walls of the notch of the first positioning groove 4, and the positioning steps 18 have a step surface abutting against the bottom wall of the suspension flexible shaft 15 to limit the bottom wall of the suspension flexible shaft 15 along the axial direction of the first positioning groove 4.

[0067] The notch of the first positioning groove 4 is provided with a positioning step 18. The purpose of the positioning step 18 is to be able to be used to position the suspension flexible shaft 15. The step surface of the positioning step 18 can abut against the bottom wall of the suspension flexible shaft 15, thereby ensuring the installation accuracy of the suspension flexible shaft 15. The suspension flexible shaft 15 will not move downward along the first positioning groove 4, thereby ensuring the installation position of the suspension flexible shaft 15, facilitating installation with the suspension bracket 16, and improving the efficiency of assembly.

[0068] The structure of the second positioning component 3 is not limited by the present application, and any of the following implementations may be adopted:

[0069] Embodiment 1: The second positioning assembly 3 includes a second support 31 and a second positioning seat 32, the second support 31 is connected to the base 1, the second positioning seat 32 is symmetrically connected to both sides of the second support 31 along the length direction of the second support 31, and the top of the second positioning seat 32 has a second positioning pin 7 for installing the fixed end of the suspension bracket 16.

[0070] The second support 31 is used to support and connect the second positioning seat 32. The second positioning seat 32 is used to install and position the suspension bracket 16 assembly formed by the fully assembled suspension flexible shaft 15 and the suspension bracket 16, and to position and connect the suspension hanger 17 to the second positioning seat 32 to complete the assembly with the suspension bracket 16; the top of the second positioning seat 32 has a plurality of second positioning pins 7, and the second positioning pins 7 are symmetrically connected to the top of the second support 31, the purpose is to facilitate the symmetrical connection with the suspension bracket 16 in the suspension bracket 16 assembly, and ensure that the suspension bracket 16 is evenly stressed on the second positioning seat 32. Figure 3As shown, after the suspension bracket 16 assembly is taken out from the first positioning component 2 and turned over, the two positioning holes connecting the suspension bracket 16 of the suspension bracket 16 assembly with the first positioning pin 6 are respectively positioned with the second positioning pin 7, and the complete suspension bracket 16 assembly is positioned on the second support 31, and the through hole of the suspension hanger 17 for docking with the bolt 8 of the suspension flexible shaft 15 is sleeved on the outer side of the bolt 8 of the corresponding suspension flexible shaft 15, and the pin shaft 9 of the suspension flexible shaft 15 is positioned with the hole of the suspension hanger 17, and the side surface of the suspension hanger 17 can abut against the side surface of the second support 31 facing the second end 14 of the base, so as to realize the dual positioning of the positioning point where the pin shaft 9 of the suspension hanger 17 is located and the positioning surface where the second support 31 and the side surface of the suspension hanger 17 are located, and the bolt 8 can be tightened by an electric tool to assemble the suspension hanger 17 and the suspension bracket 16 assembly.

[0071] It is worth noting that the bottom wall of the second positioning groove 5 has an inclined guide slope 10, the purpose of which is to be able to adapt to the connecting end of the suspension bracket 16 of the suspension bracket 16 assembly, and the side walls of the second positioning groove 5 are used to abut and connect with the two sides of the suspension bracket 16 to achieve the positioning of the two sides of the suspension bracket 16, thereby ensuring that the suspension bracket 16 assembly is fixed in the second positioning groove 5, preventing the suspension bracket 16 assembly and the suspension hanger 17 from offsetting between the suspension hanger 17 and the suspension bracket 16 assembly during the subsequent installation process, thereby further improving the positioning accuracy.

[0072] Embodiment 2: The second positioning assembly 3 includes a second support 31, which is connected to the base 1. The top of the second support 31 has at least two positioning bosses protruding from the second support 31, and the positioning boss has a second positioning pin 7 for installing the fixed end of the suspension bracket 16.

[0073] In the second embodiment, the top of the second support 31 has a positioning boss protruding upward, and a second positioning pin 7 is provided above the positioning boss to facilitate positioning and installation with the suspension bracket 16 in the suspension bracket 16 assembly.

[0074] As a preferred embodiment, a second positioning groove 5 for installing the suspension bracket 16 assembly is formed between the two positioning bosses; the second positioning groove 5 has a first abutting surface for abutting against two sides of the suspension bracket 16, and a second abutting surface abutting against the outer wall of the connecting end of the suspension bracket 16.
