[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] like Figure 1-Figure 13 As shown, this embodiment provides a fixture for a CNC machine tool for processing the housing of a new energy vehicle motor, including a fixture 100 arranged inside a CNC machine tool 200, a rotating mechanism 300 is installed at the bottom of the fixture 100, a transverse mechanism 400 is installed at the bottom of the rotating mechanism 300, and the transverse mechanism 400 is installed at the bottom of the inner cavity of the CNC machine tool 200.

[0034] The fixture body 101 of the fixture 100 is connected to the rotating end of the rotating mechanism 300, and the rotating mechanism 300 drives the fixture 100 to rotate 360 ​​degrees horizontally. The rotating mechanism 300 is connected to the moving end of the transverse mechanism 400, and the transverse mechanism 400 drives the rotating mechanism 300 and the fixture 100 to move left and right to change the processing angle and position of the motor housing by the CNC machine tool 200.

[0035] By setting up the clamp 100, the motor housing can be easily clamped and fixed. When the motor housing is processed, the clamp 100 is used to fix the motor housing, and the tool inside the CNC machine tool 200 processes the motor housing. The rotating mechanism 300 drives the clamp 100 to rotate, and the transverse mechanism 400 drives the clamp 100 to move left and right to change the processing angle and position of the motor housing.

[0036] The clamp 100 includes a clamp body 101 , and a plurality of clamping claw mechanisms 102 and supporting columns 105 are installed on the left and right sides of the front of the clamp body 101 . The supporting columns 105 support the rear side of the motor housing, and the clamping claw mechanisms 102 fix the front side of the motor housing.

[0037] A hydraulic rod 106 is fixedly connected to the top of the clamp body 101, and the piston rod of the hydraulic rod 106 is fixedly connected to the clamping head 103. A multi-point support mechanism 104 used in conjunction with the clamping head 103 is fixedly installed at the bottom of the inner wall of the clamp body 101. The clamping head 103 and the multi-point support mechanism 104 fix the top and bottom of the motor housing.

[0038] The clamping claw mechanism 102 includes a mounting block 1021 , which is mounted on the fixture body 101 . A mounting column 1022 is fixedly connected to one side of the mounting block 1021 , and a threaded column 1024 is fixedly connected to one end of the mounting column 1022 .

[0039] A limit claw 1025 is movably sleeved on the surface of the threaded column 1024 , and a nut sleeve 1023 for fixing the limit claw 1025 is threadedly sleeved on the surface of the threaded column 1024 . The support column 105 is located at one side of the limit claw 1025 .

[0040] The coordinated use of the clamping mechanism 102 and the support column 105 can facilitate the fixing of the front and rear sides of the motor housing. The coordinated use of the hydraulic rod 106, the clamping head 103 and the multi-point support mechanism 104 can facilitate the fixing of the upper and lower sides of the motor housing. When fixing the motor housing, the motor housing is placed on the top of the multi-point support mechanism 104, and the support column 105 is pressed against the rear side of the motor housing to limit it. The limiting clamping claw 1025 is sleeved on the surface of the threaded column 1024 and pressed against the front side of the motor housing. The nut sleeve 1023 is screwed on the surface of the threaded column 1024. The threaded column 1 024 applies pressure to the limiting claw 1025, so that the limiting claw 1025 fixes the front side of the motor housing. After the fixing is completed, the piston rod of the hydraulic rod 106 drives the clamping head 103 to move downward, and the clamping head 103 is against the top of the motor housing and fits the shape of the top of the motor housing. The multi-point support mechanism 104 supports the different surfaces of the bottom of the motor housing. The upper and lower sides of the motor housing are fixed by fixing the clamping head 103 and the multi-point support mechanism 104, thereby finally realizing effective support of the motor housing, avoiding partial suspension of the motor housing, and preventing local stress deformation of the motor housing during processing.

[0041] The clamping head 103 includes a ring body 1031 , the inner part of the ring body 1031 is threadedly connected with a threaded member 1033 , the threaded member 1033 is fixedly connected to the piston rod of the hydraulic rod 106 , and the bottom of the ring body 1031 is fixedly connected with an elastic membrane 1032 .

[0042] The bottom of the ring body 1031 is fixedly connected with a base 1034 , the surface of the base 1034 is movably connected with the inner wall of the elastic membrane 1032 , and the base 1034 has electromagnets 1035 distributed in a circular array fixedly installed inside.

[0043] A rubber spiral piece 1036 is fixedly connected to the bottom of the inner wall of the elastic membrane 1032 , and the top of the rubber spiral piece 1036 is fixedly connected to the bottom of the base 1034 .

[0044] The inner cavity of the elastic membrane 1032 is filled with a shaped filler 1037 used in conjunction with the electromagnet 1035 , the rubber spiral piece 1036 is located in the shaped filler 1037 , and a replacement hole used in conjunction with the shaped filler 1037 is opened at the center of the ring body 1031 and the base 1034 .

[0045] The shaped filler 1037 includes electromagnetic powder and silicone oil, the ratio of the electromagnetic powder to the silicone oil is 7:3, the electromagnetic powder is carbonyl iron powder or iron silicon aluminum alloy powder, and the particle size is 50-150 μm.

[0046] The elastic membrane 1032 includes an outer layer 1038, a middle layer 1039 is fixedly connected to the inner side of the outer layer 1038, and an inner layer 10310 is fixedly connected to the inner side of the middle layer 1039. The outer layer 1038 is made of silicone with a Shore hardness of A30 and a thickness of 2 mm. The middle layer 1039 is made of aramid fiber. The inner layer 10310 is made of magnetic rubber with a thickness of 1 mm.

[0047] When the elastic membrane 1032 contacts the motor housing, the outer layer 1038 contacts the surface of the housing. The outer layer 1038 is soft and wear-resistant, which prevents damage to the surface of the elastic membrane 1032 and can deform it. The middle layer 1039 is located in the middle to improve the tensile strength of the elastic membrane 1032. The inner layer 10310 is located at the innermost side and contacts the shaping filler 1037, which can enhance the penetration of the magnetic field and assist the elastic membrane 1032 to follow the shaping filler 1037 to shape.

[0048] The blade height of the rubber spiral piece 1036 is 5-8mm, and the spiral is 15-20mm, which guides the particles of the shaped filler 1037 to flow along the spiral path to avoid local accumulation. The rubber spiral piece 1036 is made of high-elastic silicone. The Shore hardness of the high-elastic silicone is A40-50, and the compression rebound rate is ≥95%, which can assist the elastic membrane 1032 in resetting.

[0049] By setting the clamping head 103, the shape of the top of the motor housing can be fitted. During the operation of the clamping head 103, the piston rod of the hydraulic rod 106 pushes the clamping head 103 to contact the motor housing. The elastic membrane 1032 deforms when it contacts the motor housing and fits the shape of the top of the motor housing. The shaped filler 1037 flows and fills the gap under the action of pressure. The rubber spiral sheet 1036 shrinks under pressure. When the elastic membrane 1032 is completely fitted, the electromagnet 1035 is controlled to be energized, and the electromagnet 1035 applies a 0.05T magnetic field to the shaped filler 1037. The carbonyl iron powder or iron-silicon-aluminum alloy powder in the shaping filler 1037 forms a chain structure along the magnetic flux lines. The silicone oil in the shaping filler 1037 can facilitate the flow of particles. Then the magnetic field is strengthened. A 0.3T magnetic field is applied to trigger the particles to be closely arranged. The shear modulus jumps from 10kPa to 1GPa, forming a fixed structure that fits the top of the motor housing. After the fixation is completed, the cylinder pressure drops to 0.1MPa, and the clamping force is maintained by magneto-solidification. When the processing is completed, the electromagnet 1035 is controlled to be on and off, and the rubber spiral piece 1036 drives the shaping filler 1037 to reset.

[0050] The multi-point support mechanism 104 includes a support shell 1041 , which is fixedly mounted on the bottom of the inner wall of the clamp body 101 , and an elastic sleeve 1042 is fixedly connected to the top of the support shell 1041 . The support shell 1041 and the elastic sleeve 1042 are located at the bottom of the clamping head 103 .

[0051] The inner wall of the support shell 1041 is fixedly connected with a mounting frame 1043 , and a plurality of support components 1044 are installed inside the mounting frame 1043 . The top of the support component 1044 is movably connected with the bottom of the elastic sleeve 1042 .

[0052] The mounting frame 1043 includes a supporting ball head 1045, the top of the supporting ball head 1045 is movably connected to the bottom of the elastic sleeve 1042, the bottom of the supporting ball head 1045 is fixedly connected to a piston 1046, the surface of the piston 1046 is slidably connected to a first tube body 10411, the bottom of the piston 1046 is fixedly installed with a pressure sensor 10414 and a spring 10412, the pressure sensor 10414 is located inside the spring 10412, and the inner cavity of the first tube body 10411 is filled with hydraulic oil.

[0053] The second tube body 10410 is fixedly connected to the bottom of the first tube body 10411, and a solenoid valve 10413 is fixedly installed on the top of the inner cavity of the second tube body 10410. The liquid inlet end of the solenoid valve 10413 penetrates to the bottom of the inner cavity of the first tube body 10411, and the liquid outlet end of the solenoid valve 10413 is connected to a rubber oil bag 1047. The bottom of the rubber oil bag 1047 is movably connected to a threaded support seat 1049, and the surface of the threaded support seat 1049 is threadedly connected to the inner wall of the second tube body 10410.

[0054] A plurality of reset rings 1048 are fixedly connected to the inner cavity of the second tube body 10410 , and the reset rings 1048 are movably sleeved on the surface of the rubber oil bag 1047 to assist in its reset.

[0055] The reset ring 1048 includes an elastic ring 10415 movably mounted on the surface of the rubber oil bag 1047, a plurality of elastic sheets 10416 are fixedly connected to the surface of the elastic ring 10415, a bent steel wire 10417 is fixedly connected inside the elastic sheet 10416, and a fixing ring 10418 is fixedly connected to one end of the elastic sheet 10416 away from the elastic ring 10415, and the surface of the fixing ring 10418 is fixedly connected to the inner wall of the second tube body 10410.

[0056] By setting a multi-point support mechanism 104, the bottom of the motor housing can be supported. The support shell 1041 fixes several support components 1044 through the mounting frame 1043. The support components 1044 can effectively support multiple planes, curved surfaces and anisotropic surfaces at the bottom of the motor housing. The motor housing contacts the support ball head 1045 through the elastic sleeve 1042. The support ball head 1045 contacts the surfaces of different heights at the bottom of the motor housing to provide multi-point support. The support ball head 1045 can automatically adjust the support height according to the contact pressure. When the support ball head 1045 is subjected to pressure, it drives the piston 1046 to slide inside the first tube body 10411 to pressurize the hydraulic oil inside the first tube body 10411. The pressure sensor 10414 detects the pressure. When the pressure is higher than the set pressure When the pressure is applied, the solenoid valve 10413 is opened, and the solenoid valve 10413 discharges the hydraulic oil in the inner cavity of the first tube body 10411 into the rubber oil bag 1047, so that the supporting ball head 1045 can descend. When the pressure reaches the set value, the solenoid valve 10413 is closed to maintain the supporting height of the supporting ball head 1045. After the hydraulic oil enters the rubber oil bag 1047, the rubber oil bag 1047 expands and squeezes the reset ring 1048. When the support is completed, the solenoid valve 10413 is opened, and the reset ring 1048 drives the rubber oil bag 1047 to reset, so that the excess hydraulic oil in the rubber oil bag 1047 flows back to the first tube body 10411 to drive the supporting ball head 1045 to reset. At the same time, the spring 10412 is also stretched, driving the piston 1046 to move upward, assisting the supporting ball head 1045 to reset.

[0057] During the operation of the reset ring 1048, the elastic ring 10415 drives the elastic sheet 10416 and the bending steel wire 10417 to deform, and the fixing ring 10418 fixes one end of the elastic sheet 10416 and the bending steel wire 10417. When the rubber oil bag 1047 does not apply pressure to the elastic ring 10415, the elastic sheet 10416 and the bending steel wire 10417 drive the elastic ring 10415 to reset and squeeze the rubber oil bag 1047.
