[0021] The top surface of the workbench 10 is provided with a first groove 11 and a second groove 12 , the first groove 11 and the second groove 12 are parallel, the conveyor belt 20 is arranged through the first groove 11 , and the upper surface of the conveyor belt 20 is flush with the upper surface of the workbench 10 .

[0022] It can be understood that the half-bridge shells 60 are placed on the conveyor belt 20 in sequence. By manipulating the positioning mechanism, the half-bridge shells 60 transported on the conveyor belt 20 can be removed and cut in sequence, and then sent back after cutting, thereby ensuring efficient cutting processing.

[0023] In addition, when the half axle housing 60 is removed from and placed on the conveyor belt 20, the half axle housing 60 can be horizontally transferred between the workbench 10 and the conveyor belt 20, which helps to stably position the half axle housing 60 subsequently.

[0024] It should be noted that the conveyor belt 20 described in this embodiment is an integration of rollers or wheels, idlers and a driving device, etc. Due to the prior art, it will not be elaborated here.

[0025] The cutting mechanism 30 and the positioning mechanism are respectively arranged on the symmetric two sides of the second groove 12.

[0026] The positioning mechanism may include an outer positioning member 41 and an inner positioning member 42. Among them, the outer positioning member 41 and the inner positioning member 42 are respectively arranged on the symmetric two sides of the conveyor belt 20.

[0027] The outer positioning member 41 may include a first driving component 411, a C-shaped frame 412 and two clamps 413. Among them, the output end of the first driving component 411 is connected to the C-shaped frame 412; both ends of the C-shaped frame 412 are respectively connected to the clamps 413, and the clamps 413 are horizontally arranged.

[0028] It should be noted that the first driving component 411 described in this embodiment may be a telescopic motor, a cylinder, etc. The first driving component 411 can drive the C-shaped frame 412 to move horizontally. Cooperating with the two clamps 413, it can realize the functions of removing and placing the half axle housing 60 on the conveyor belt 20.

[0029] The inner positioning member 42 may include a vertical seat 421 and a plurality of inner support rods 422. Among them, the vertical seat 421 is arranged on the central axis of the C-shaped frame 412, and the plurality of inner support rods 422 are circumferentially distributed on the outside of the vertical seat 421, and a telescopic section 4221 is arranged on the inner support rods 422.

[0030] It should be noted that the telescopic section 4221 described in this embodiment may be a telescopic motor, a pneumatic rod, etc. The plurality of inner support rods 422 can circumferentially abut against the middle arc-shaped notch of the half axle housing 60. By arranging the telescopic section 4221, the plurality of inner support rods 422 can be synchronously telescoped to adapt to the support and positioning of the middle arc-shaped notches of half axle housings 60 of different sizes. And according to the size of the half axle housing 60 to be cut as required in advance, the length of the inner support rods 422 can be adjusted through the telescopic section 4221, so as to improve the positioning efficiency of the half axle housing 60.

[0031] It can be understood that the half axle housing 60 is a half shell with semi-circular cross-sections at both ends and an arc-shaped notch in the middle. The welding surface of the half axle housing 60 on the conveyor belt 20 faces the second groove 12. The C-shaped frame 412 and the plurality of inner support rods 422 can respectively abut against both sides of the half axle housing 60 and perform multi-point positioning on the half axle housing 60, and the two clamps 413 can respectively clamp both ends of the half axle housing 60.

[0032] Specifically, during the actual operation of the welding surface of the half axle housing 60, when the conveyor belt 20 conveys the half axle housing 60 to a suitable position in the first groove 11, the relevant personnel first start the first driving component 411, so that the first driving component 411 drives the U-shaped frame 412 to move horizontally. The movement of the U-shaped frame 412 can push the half axle housing 60 on the conveyor belt 20 to the upper surface of the workbench 10, and the middle part of the half axle housing 60 is sleeved outside multiple inner support rods 422, and the welding surface of the half axle housing 60 is located in the second groove 12.

[0033] At this time, the U-shaped frame 412 and multiple inner support rods 422 can respectively abut against both sides of the half axle housing 60, and perform multi-point positioning on the half axle housing 60, and then two clamps 413 can be controlled to clamp both ends of the half axle housing 60 respectively.

[0034] Subsequently, the welding surface of the half axle housing 60 can be cut and flattened by the cutting mechanism 30.

[0035] Finally, the first driving component 411 drives the half axle housing 60 to reset, so that the cut half axle housing 60 is placed on the conveyor belt 20, and by repeating the operation, multiple half axle housings 60 on the conveyor belt 20 can be cut in sequence.

[0036] In an embodiment of the present utility model, as Figure 1 and Figure 2 shown, the clamp 413 includes a first clamping plate 4131, a second clamping plate 4132 and an angle adjuster 4133 arranged in an L shape. Among them, one end of the first clamping plate 4131 is connected to the U-shaped frame 412, and the other end of the first clamping plate 4131 is rotatably connected to the second clamping plate 4132 through the angle adjuster 4133. The second clamping plate 4132 is linearly arranged.

[0037] It should be noted that the angle adjuster 4133 described in this embodiment can control the second clamping plate 4132 to rotate horizontally, so that the first clamping plate 4131 and the second clamping plate 4132 clamp the end of the half axle housing 60 together.

[0038] In an embodiment of the present utility model, as Figure 1 and Figure 2 shown, the cutting mechanism 30 includes a slide table module 31, a second driving component 32 and a cutting tool 33. Among them, the slide table module 31 is parallel to the second groove 12, the second driving component 32 is arranged on the slide of the slide table module 31, the output end of the second driving component 32 is connected to the cutting tool 33, and the cutting tool 33 is vertically arranged in the second groove 12.

[0039] It should be noted that the second driving component 32 described in this embodiment is a reduction motor, a servo motor, etc. The second driving component 32 can drive the cutting tool 33 to rotate, so that the cutting tool 33 performs a cutting operation on the half axle housing 60 in the second groove 12.

[0040] Specifically, when relevant personnel cut the welding surface of the half axle housing 60 through the cutting mechanism 30, first, the second driving component 32 drives the cutting tool 33 to rotate, and then the sliding table module 31 drives the second driving component and the cutting tool 33 to linearly move in the second groove 12, so that the cutting tool 33 performs a cutting operation on the welding surface of the half axle housing 60 in the second groove 12.

[0041] In an embodiment of the present utility model, as Figure 1 shown, a plurality of auxiliary positioning rods 50 are symmetrically arranged inside the C-shaped frame 412, and the auxiliary positioning rods 50 are parallel to both sides of the C-shaped frame 412.

[0042] It can be understood that the arranged auxiliary positioning rods 50 can increase the positioning fulcrums of the positioning mechanism for the half axle housing 60, which helps to more stably limit the half axle housing 60.

[0043] In summary, the cutting device for the electric vehicle rear axle housing in the embodiment of the present utility model can perform multi-point positioning on the half axle housing through the positioning mechanism, thereby effectively improving the stability during the movement and cutting of the half axle housing. At the same time, the half axle housing can be conveniently removed from and placed on the conveyor belt, thus ensuring the efficient progress of the cutting process.
