Description

Technical Field

[0001] This utility model belongs to the field of engine housing production technology, specifically relating to a positioning fixture for engine housing sheet metal parts. Background Technology

[0002] In the new energy vehicle industry, with the continuous advancement of global industrialization, automotive electronics technology has become an important direction for the upgrading of the automotive industry. 48V hybrid technology can provide better driving control for the entire vehicle. With this technology, the engine can start immediately, allowing for exceptionally smooth driving control from the moment the vehicle starts. The 48V integrated starter motor effectively reduces the load on the internal combustion engine, especially when driving in urban conditions, resulting in lower fuel consumption and stronger dynamic performance: utilizing recovered electrical energy, the 48V integrated starter motor can provide power to the internal combustion engine, giving the vehicle stronger acceleration performance.

[0003] In the production process of a 48V integrated starter motor, several external sheet metal parts need to be installed onto the 48V mild hybrid enclosure. The current method involves fixing the enclosure, manually pre-installing the sheet metal parts, and then using a hand-held electric screwdriver to screw the fasteners through the sheet metal parts into the mounting holes in the enclosure. However, this method is only suitable for installing sheet metal parts on one side of the enclosure. If installation is required on multiple sides, the enclosure must be flipped over manually for fixing, resulting in low production efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] This application provides a positioning fixture for an engine housing sheet metal part, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0020] See Figures 1 to 3 In one embodiment, the engine housing sheet metal positioning fixture includes: a base plate 1, the back of which is vertically mounted on a rotating seat 2, and the front of which is provided with a housing positioning groove 11 for accommodating the housing 100; a plurality of housing clamping devices 3 for clamping and fixing the housing 100 in the housing positioning groove 11; and a plurality of sheet metal clamping devices 4, which are disposed on the side of the base plate 1 for clamping and fixing the corresponding sheet metal parts 200 to be installed on the sheet metal mounting position of the housing 100; wherein the rotating seat 2 is used to rotate the housing 100 to the side orientation after the sheet metal parts 200 on the top surface of the housing 100 are fixed by the fixing members 300, so as to install the fixing members 300 on the side of the sheet metal parts 200 of the housing 100.

[0021] In one application scenario, after the box 100 is placed into the box positioning groove 11, the box 100 can be clamped and fixed in the box positioning groove 11 by the box clamping device 3; then the sheet metal part 200 is pre-installed on the sheet metal mounting position of the box 100 and fixed by the sheet metal clamping device 4; after the box 100 and the sheet metal part 200 are installed, since the box 100 is placed vertically, the fastener 300 can be screwed into the mounting hole on the top surface of the box 100 from top to bottom by manual or automatic screw driving machine, which is convenient for operation; after the fastener 300 on the top surface is screwed, the corresponding sheet metal part 200 has been fixed on the top surface of the box 100. Then, the box 100 is rotated to the side by the rotating seat 2, and the fastener 300 is screwed into the mounting hole on the side of the box 100 from top to bottom by manual or automatic screw driving machine to fix the corresponding sheet metal part 200 on the side of the box 100. Of course, if there are other sheet metal parts 200 that need to be installed on other sides, the housing 100 can be rotated to face the corresponding side by rotating the rotating seat 2.

[0022] In this embodiment, the box 100 and sheet metal parts 200 only need to be fixed once. When installing the fasteners 300 on different surfaces, the box 100 can be rotated to face the corresponding surface by the rotating seat 2. This is convenient to operate and has high production efficiency.

[0023] See Figure 3 and Figure 4 Optionally, positioning blocks 111 protruding from the bottom of the positioning groove 11 are provided on the inner walls of both sides of the box positioning groove 11; the positioning blocks 111 are used to cooperate with the recesses 101 provided on the back of the box 100.

[0024] The back of the housing 100 is provided with a recess 101 that corresponds one-to-one with the positioning block 111.

[0025] Furthermore, the bottom of the positioning groove 11 of the box body is provided with a plurality of positioning posts 112 for passing through the corresponding positioning holes 102 on the box body 100.

[0026] See Figure 1 and Figure 3 Since the box 100 cannot be completely contained in the box positioning groove 11, in order to effectively support the weight of the box 100, optionally, a number of support rods 12 are provided on the front of the bottom plate 1, which can be used to support the bottom surface of the box 100.

[0027] See Figure 3 Optionally, the box clamping device 3 includes: a clamping cylinder 31, which is disposed on the front side of the base plate 1; and a clamping rod 32, which is fixed to the drive end of the clamping cylinder 31.

[0028] In some embodiments, the housing clamping device 3 may be located on both sides of the housing positioning groove 11.

[0029] See Figure 5 Optionally, the sheet metal clamping device 4 includes: a mounting base 41, fixed on the top surface and / or side surface of the base plate 1; and a quick clamp 42, disposed on the mounting base 41, for clamping and fixing the corresponding sheet metal part 200 to be installed on the mounting base 41.

[0030] In this embodiment, one end of the sheet metal part 200 is provided with a mounting hole for alignment with the mounting hole on the housing 100, and the quick clamp 42 and the mounting base 41 can cooperate to clamp and fix the other end of the sheet metal part 200.

[0031] In some embodiments, the sheet metal clamping device 4 can be provided as needed, and it can be located on the same side of the housing 100 or on different sides.

[0032] See Figure 6Optionally, the rotating seat 2 includes: a fixed seat 21; a turntable 22 rotatably mounted on the fixed seat 21; the back of the base plate 1 is detachably connected to the turntable 22; and a driving device 23 mounted on the fixed seat 21 for driving the turntable 22 to rotate.

[0033] In this embodiment, the drive device 23 may be, but is not limited to, a motor, a manual rotation device, etc. The back of the base plate 1 is detachably connected to the turntable 22, which facilitates the installation of different base plates 1 according to different models of housings.

[0034] In summary, the engine housing sheet metal positioning fixture of this utility model can clamp and fix the housing in the housing positioning groove through the housing clamping device, and clamp and fix the corresponding sheet metal parts to be installed on the sheet metal mounting position of the housing through the sheet metal clamping device. After the sheet metal parts on the top surface of the housing are fixed by the fasteners, the rotating seat can drive the housing to rotate to the side to install the fasteners of the sheet metal parts on the side of the housing. This avoids the housing and sheet metal parts being fixed again after the housing is flipped over, thus improving production efficiency.
