[0002] like Figure 1 - Figure 4 As shown, the existing housing assembly 100 includes a housing 110 and a mounting plate 120. The housing 110 has a cavity 111, and one side wall and the bottom wall of the cavity 111 are open. The housing 110 has a mounting hole 112 and a first through hole 113 communicating with the cavity 111. The mounting hole 112 and the first through hole 113 are both located on the top wall of the cavity 111. The mounting plate 120 has a triangular structure and has a front side 121 and a back side 122. The center of the mounting plate 120 has an inwardly recessed boss 123. The inwardly recessed boss 123 is... The mounting plate 120 has a columnar structure, and the length of the protrusion of the concave boss 123 is less than the length of the mounting hole 112. The concave part of the concave boss 123 is located on the front side 121, and the protrusion of the concave boss 123 is located on the back side 122. A second through hole 124 is provided at the center of the mounting plate 120. The second through hole 124 is located on the concave boss 123 and is coaxial with the concave boss 123. The protrusion of the concave boss 123 is used to slide into the mounting hole 112, and the back side 122 of the mounting plate 120 abuts against the top surface of the housing 110. In the process of producing the housing assembly with the above structure, the protrusion of the inner concave boss of the mounting plate is slid into the mounting hole of the housing, and the back of the mounting plate is brought into contact with the top surface of the housing. Then, a positioning fixture is used to position the housing assembly, and a welding machine is used to weld the connection between the mounting plate and the housing. Existing positioning fixtures (such as the aluminum tube welding positioning fixture disclosed in application number 202221273709.5) are not suitable for positioning the housing assembly of this structure. When using existing positioning fixtures to position the housing assembly of this structure, the housing assembly is prone to movement during the welding process, resulting in poor positioning effect of the housing assembly and reduced welding efficiency.

The top surface of the fixed platform 200 is used to abut against the top surface of the cavity 111 of the housing 110. The first positioning hole 210 corresponds to the first through hole 113 of the housing 110, and the second positioning hole 220 corresponds to the second through hole 124 of the mounting plate 120. The first positioning member 300 is used to slide into the first through hole 113 and the first positioning hole 210. The second positioning member is used to slide into the second through hole 124 and the second positioning hole 220.

[0029] In use, place the housing 110 on the fixed platform 200, with the top surface of the fixed platform 200 abutting against the top surface of the cavity 111 of the housing 110. Then, slide the protrusion of the inner concave boss 123 of the mounting plate 120 into the mounting hole 112 of the housing 110, and make the back surface 122 of the mounting plate 120 abut against the top surface of the housing 110. Adjust the position of the housing assembly 100 so that the first through hole 113 of the housing 110 corresponds to the first positioning hole 210, and the second through hole 124 of the mounting plate 120 corresponds to the second positioning hole 220. Then, slide the first positioning member 300. Insert the second positioning member into the first through hole 113 and the first positioning hole 210, and slide it into the second through hole 124 and the second positioning hole 220. This allows for the positioning of the housing 110 and the mounting plate 120 of the housing assembly 100. This housing assembly welding positioning fixture is suitable for positioning the housing 110 and the mounting plate 120 of the housing assembly 100 of this structure. It ensures that the housing 110 and the mounting plate 120 will not move during the welding process at the connection between the housing 110 and the mounting plate 120, thereby improving the positioning effect of the housing assembly 100 and increasing the welding efficiency.

[0030] As a preferred embodiment, please refer to Figure 5 and Figure 6 The fixed platform 200 includes a base 230, a first support 240, and a second support 250.

The second support 250 is disposed within the receiving groove 241. The top surface of the second support 250 abuts against the cavity 111 of the housing 110. The bottom surface of the concave boss 123 of the mounting plate 120 abuts against the second bearing seat 250, which has the second positioning hole 220. The housing 110 is placed on the fixed platform 200, and the top surface of the fixed platform 200 abuts against the top surface of the cavity 111 of the housing 110. Then, the protrusion of the concave boss 123 of the mounting plate 120 is slid into the mounting hole 112 of the housing 110, and the back surface 122 of the mounting plate 120 abuts against the top surface of the housing 110. The bottom surface of the concave boss 123 of the mounting plate 120 abuts against the top surface of the second bearing seat 250, which can improve the bearing effect of the housing assembly 100.

[0031] As a preferred embodiment, please refer to Figure 6Both the first positioning hole 210 and the second positioning hole 220 extend vertically. Since the housing 110 is placed on the fixed platform 200 and the top surface of the fixed platform 200 abuts against the top surface of the cavity 111 of the housing 110, the first through hole 113 of the housing 110 and the second through hole 124 of the mounting plate 120 both extend vertically. The fact that both the first positioning hole 210 and the second positioning hole 220 extend vertically ensures that the first positioning hole 210 corresponds to the first through hole 113 and the second positioning hole 220 corresponds to the second through hole 124.

[0032] As a preferred embodiment, please refer to Figure 5 and Figure 6 The diameter of the first positioning hole 210 is smaller than the diameter of the first through hole 113.

The diameter of the second segment is equal to the diameter of the first through hole 113 and is used to insert into the first through hole 113. This can improve the connection effect between the first positioning member 300 and the first positioning hole 210 and the first through hole 113.

[0033] As a preferred embodiment, please refer to Figure 5 and Figure 6 The second positioning hole 220 includes a lower section and an upper section that are interconnected. The diameter of the lower section is smaller than the diameter of the upper section, and the diameter of the upper section is equal to the diameter of the second through hole 124. The second positioning member is a columnar structure and includes a third section and a fourth section that are fixedly connected. The diameter of the third section is equal to the diameter of the lower section of the second positioning hole 220 and is used to be inserted into the lower section. The diameter of the fourth section is equal to the diameter of the upper section of the second positioning hole 220 and the diameter of the second through hole 124, and is used to be inserted into the upper section and the second through hole 124. This can improve the connection effect between the second positioning member and the second positioning hole 220 and the second through hole 124.

[0034] As a preferred embodiment, please refer to Figure 5 and Figure 6 The top surfaces of the first support 240 and the second support 250 are both horizontal, so that the top surface of the first support 240 can abut against the top surface of the cavity 111 of the housing 110, and the top surface of the second support 250 can abut against the bottom surface of the concave boss 123 of the mounting plate 120.

[0035] As a preferred embodiment, please refer to Figure 5 and Figure 6 The top surface of the second support 250 is higher than the top surface of the first support 240. Since the length of the protrusion of the recessed boss 123 of the mounting plate 120 is less than the length of the mounting hole 112 of the housing 110, when the protrusion of the recessed boss 123 of the mounting plate 120 slides into the mounting hole 112 of the housing 110, and the back surface 122 of the mounting plate 120 abuts against the top surface of the housing 110, there is still a certain distance between the bottom surface of the recessed boss 123 of the mounting plate 120 and the top surface of the cavity 111 of the housing 110. The top surface of the second support 250 is higher than the top surface of the first support 240. When the housing 110 is placed on the first support 240, the top surface of the cavity 111 of the housing 110 abuts against the top surface of the first support 240. Then, the protrusion of the concave boss 123 of the mounting plate 120 is slid into the mounting hole 112 of the housing 110, and the back surface 122 of the mounting plate 120 abuts against the top surface of the housing 110.
