Detailed Implementation

[0028] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0029] like Figure 1-7 As shown, an elliptical aluminum shell trimming fixture is characterized by:

[0030] Base plate 1, wherein an aluminum shell positioning device is fixed in the middle of the base plate 1;

[0031] A cutting tool mechanism is fixed to one side of the base plate 1, and the cutting tool mechanism can feed downwards;

[0032] A sliding positioning component is slidably mounted on the other side of the base plate 1 to hold one end of the aluminum shell 6.

[0033] The clamping mechanism 14 is fixed on both sides of the aluminum shell positioning mechanism;

[0034] The aluminum shell positioning mechanism includes a left positioning block 12 and a right positioning block 13. The left positioning block 12 and the right positioning block 13 are respectively provided with a first mounting groove and a second mounting groove for placing the aluminum shell 6. The pressing end of the pressing mechanism 14 acts on the aluminum shell 6 to press the aluminum shell 6 onto the aluminum shell positioning device.

[0035] Furthermore, the cutting tool mechanism includes a guide post 151, an upper mold frame 16, an upper template 15, a first cutting edge upper blade 161, and a second cutting edge upper blade 162. The guide post 151 is vertically fixed on two corners on the same side of the base plate 1. The two ends of the upper template 15 are connected to the guide post 151 and can move up and down along the guide post 151. The upper mold frame 16 is installed at the lower end of the upper template 15. The first cutting edge upper blade 161 and the second cutting edge upper blade 162 are installed on the upper mold frame 16 and correspond to the left positioning block 12 and the right positioning block 13, respectively.

[0036] Furthermore, the lower end of the upper mold frame 16 is spaced from the base plate 1 to allow the tool mechanism to feed downwards.

[0037] Furthermore, the left positioning block 12 has a relief groove 123 corresponding to the first cutting edge upper blade 161, and a cutting edge lower blade 121 is fixed inside the relief groove 123. The first cutting edge upper blade 161 feeds downward and acts on the aluminum shell 6, and the cutting edge lower blade 121 removes the excess part.

[0038] Furthermore, the surface of the cutting blade 121 is aligned with the surface of the first positioning groove 122. This arrangement does not affect the placement of the aluminum shell 6, allowing the aluminum shell 6 to be placed stably on the first positioning groove 122.

[0039] Furthermore, the shapes of the first positioning groove 122 and the second positioning groove 131 correspond to the shape of the elliptical aluminum shell 6. The first positioning groove 122 is semi-elliptical and is positioned to accommodate the first cutting process of the aluminum shell 6, while the second positioning groove 131 is semi-circular and is positioned to accommodate the removal of burrs after the aluminum shell 6 is flipped over.

[0040] Furthermore, the clamping mechanism 14 includes a base 141, a hinge seat 142, a clamping arm 142, and a clamping block 144. The base 141 is fixed to one side of the left positioning block 12 and the right positioning block 13 on the base plate 1. The hinge seat 142 is fixed to the base 141. One end of the clamping arm 142 is connected to the hinge seat 142, and the other end is connected to the clamping block 144. The clamping end of the clamping block 144 has two inclined and symmetrically arranged clamping edges 145. The aluminum shell 6 is clamped by the gravity of the clamping arm 142 and the clamping block 144, and the clamping edges 145 are provided to better clamp the aluminum shell 6, adapting to aluminum shells 6 of various sizes.

[0041] Furthermore, the base plate 1 has a discharge port 3 at the positions corresponding to the first cutting edge upper blade 161 and the second cutting edge upper blade 162. The discharge port 3 facilitates the falling of the cut material.

[0042] Furthermore, the sliding positioning assembly includes a sliding seat 11 and a positioning baffle 111. The base plate 1 has a sliding strip 21 with limiting blocks 2 at both ends. The sliding seat 11 is slidably connected to the sliding strip 21, and the positioning baffle 111 is fixed to the sliding seat 11 and can press against one end of the aluminum shell 6. The positioning baffle 111 can move laterally through the slidable sliding seat 11, thereby pressing against the aluminum shell 6.

[0043] Place the oval aluminum shell 6 blank into the first positioning groove 122 of the left positioning block 12. The aluminum shell 6 should be positioned according to the shape of the first positioning groove 122. Then pull the aluminum shell 6 so that the part of the aluminum shell 6 to be cut corresponds to the first cutting edge upper blade 161. Slide the sliding seat 11 so that the head end of the aluminum shell 6 hits the positioning baffle 111. Rotate the clamping arm 142 so that the clamping block 144 presses the aluminum shell 6 to fix it. Start the equipment to punch downwards, so that the upper template 15, upper mold frame 16 and the first cutting edge upper blade 161 are punched downwards along the guide post 151 as a whole. With the help of the cutting edge lower blade 121 on the left positioning block 12, the excess part at the end of the oval aluminum shell 6 will be cut off. Then rotate the aluminum shell 6 180° and repeat the above operation to end the first cutting edge.

[0044] Place the aluminum shell 6 after the first trimming into the right positioning block 13, and place it according to the shape of the second positioning groove 131. Then push the aluminum shell 6 by hand and slide the sliding seat 11 so that the head end of the aluminum shell 6 hits the positioning baffle 111. Rotate the clamping arm 142 so that the clamping block 144 presses the aluminum shell 6 to fix it, so that the notch of the blank after the first trimming of the elliptical aluminum shell 6 abuts against the upper blade 162 of the second trimming edge. Then start the equipment to cut off the excess part. Rotate the aluminum shell 6 180° and cut it off again to obtain the final aluminum shell 6 with perfect flatness.
