[0026] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.
[0027] like Figures 1 to 4 and Figure 6As shown in the figure, this embodiment provides a tooling fixture for the battery pack housing, which includes a tooling base plate 1, a first clamping assembly 2, a second clamping assembly 3, a flushing assembly 4, and a column 5. The first clamping assembly 2 and the second clamping assembly 3 are arranged on the tooling base plate 1. The first clamping assembly 2 and the second clamping assembly 3 are respectively used to clamp the front and back sides of the battery pack housing. Among them, the first clamping assembly 2 includes a plurality of first clamping devices 20, a first supporting device 21, and a first positioning device 22. The second clamping assembly 3 includes a plurality of second clamping devices 30, a second supporting device 31, and a second positioning device 32. The height of the first clamping device 20 is higher than that of the second clamping device 30, the height of the first supporting device 21 is higher than that of the second supporting device 31, and the height of the second positioning device 22 is higher than that of the second positioning device 32. The flushing assembly 4 is symmetrically arranged at both ends of the tooling base plate 1 and is used to flush the debris generated during the processing of the battery pack housing. The column 5 is arranged on the lower surface of the tooling base plate 1, and the column 5 can install the fixture carried by the tooling base plate 1 on the airport platen.
[0028] In the present utility model, by arranging the first clamping assembly 2 and the second clamping assembly 3 on the same tooling base plate 1, the front and back sides of the battery pack housing can be integrated on the same fixture for processing, reducing the number of machine tools invested and the cost. At the same time, it can also reduce the time spent due to moving the battery pack housing to switch the fixture, resulting in a reduction in efficiency.
[0029] As Figure 1 、 Figure 2 and Figure 7 shown in the figure, in this embodiment, both the first clamping device 20 and the second clamping device 30 are composed of a pressing cylinder 200 and a receiving seat 201. The receiving seat 201 is arranged on the side where the pressing head of the pressing cylinder descends. The bottom of the receiving seat 201 is a columnar structure, and its top is a bolt. The bolt can be rotated to move up and down to adjust the height of the receiving seat 201. When clamping, the battery pack housing is placed on the receiving seat, and the pressing cylinder clamps the battery pack housing by pressing down the pressing head to prevent it from shaking during the processing.
[0030] As Figure 8 shown in the figure, in this embodiment, both the first supporting device 21 and the second supporting device 31 are composed of a base 210 and a supporting oil cylinder 211. The supporting oil cylinder 211 is arranged on the base 210. By using the supporting oil cylinder 211 to support the battery pack housing, buffering can be provided to the battery pack housing during processing to prevent damage to the battery pack housing.
[0031] As Figure 4As shown, the first positioning device 22 or the second positioning device 32 includes a positioning rod 220 and a lateral adjustment mechanism 221. The positioning rod 220 is an L-shaped plate structure, and there are two of them. The positioning rods 220 are symmetrically arranged on the tooling base plate 1. The positioning rod 220 can quickly position the battery pack housing to a specified position, facilitating the quick clamping of the battery pack housing.
[0032] As Figure 9 shown, the lateral adjustment mechanism 221 includes a cushion block 2210, an adjustment block 2211, and a positioning block 2212. The adjustment block 2211 and the positioning block 2212 are located above the cushion block 2210, and the adjustment block 2211 is fixed on the cushion block 2210. The positioning block 2212 is movably connected to the adjustment block 2211 by bolts. By rotating the bolts on the adjustment block 2211, the positioning block 2212 can be adjusted to move. When the battery pack housing is placed on the positioning device, the positioning block 2212 of the lateral adjustment structure 221 will sink into the groove on the battery pack housing or be located at the edge of the side of the battery pack housing. By adjusting the movement of the positioning block 2212, the battery pack housing can be slightly shifted horizontally to reach the specified position.
[0033] As Figure 5 shown, the flushing assembly 4 includes a connecting rod 40, a conduit 41, and a nozzle 42. The connecting rod 40 is an L-shaped columnar structure. The connecting rod 40 is fixed on the tooling base plate 1 by bolts. The conduit 41 is installed on the connecting rod 40. The conduit 41 is used to connect to a water source. The nozzles 42 are evenly distributed on the conduit. By connecting the conduit 41 to the water source, water can be sprayed from the nozzles 42 to flush the battery pack housing being processed on the tooling base plate 1, flushing away the debris generated during the processing.
[0034] As Figure 3 and Figure 4 shown, in order to be able to detect whether the battery pack housing has been placed in the specified position, the first clamping assembly 2 further includes a first installation detection assembly 23, and the second clamping assembly 3 further includes a second installation detection assembly 33. The first installation detection assembly 23 and the second installation detection assembly 33 are arranged on the tooling base plate 1. The installation detection assembly can detect whether the battery pack housing is placed in the specified position.
[0035] To facilitate the movement of the entire tooling fixture, as Figure 1 and Figure 2 shown, lifting rings 6 are also provided at the four top corners of the tooling base plate 1 for easy hoisting.
[0036] It should be noted that although the above embodiments have been described in this text, it does not thereby limit the patent protection scope of the present utility model. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this text, or equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, and directly or indirectly applying the above technical solutions to other related technical fields, are all included within the patent protection scope of the present utility model.
