DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figures 1 to 3 As shown, the motor housing clamp comprises: a mounting seat 1; a supporting assembly, which is movably arranged on the mounting seat 1, and is used to bear and drive the motor housing to move laterally; a positioning assembly, which is arranged on the mounting seat 1 and is located on the side of the supporting assembly, and when the supporting assembly moves toward the positioning assembly, it can drive the end of the motor housing to abut against the positioning assembly; a clamping assembly, which is movably arranged on the mounting seat 1 and is located on the side of the supporting assembly away from the positioning assembly, and one end of the clamping assembly abuts against the end of the motor housing and drives the other end of the motor housing to abut against the positioning assembly.

[0030] The supporting assembly is movably arranged on the mounting base 1. When the motor housing is placed on the supporting assembly, it can be driven by the supporting assembly to move laterally. When the supporting assembly drives the motor housing to move toward the positioning assembly, the positioning assembly can position the clamping position of the motor housing. The clamping assembly is movably arranged on the mounting base 1. After the positioning of the end of the motor housing is completed, the clamping assembly can move toward the motor housing, and then can abut against the motor housing and drive the other end of the motor housing to abut against the positioning assembly, so that the motor housing can be clamped.

[0031] Before the motor shell is placed in the supporting assembly, the clamping assembly is moved away from the positioning assembly, which can increase the clamping installation space of the motor shell, and is conducive to installing the motor shell with a longer stroke in the fixture. The motor shell is placed on the supporting assembly, and the supporting assembly can drive the motor shell to move laterally. During the lateral movement of the motor shell, the operator does not need to lift the motor shell all the time, which is convenient for positioning the heavier motor shell.

[0032] The supporting assembly includes: a movable plate 2, which is movably connected to the mounting base 1; a height adjustment block 3, which is movably arranged on the upper end surface of the movable plate 2, and the upper end of the height adjustment block 3 movably abuts against the side surface of the motor housing; a first fixed block 4, which is arranged at the end of the movable plate 2, and the fixed block movably abuts against the end surface of the motor housing; a second fixed block 5, which is arranged at the other end of the movable plate 2, and the second fixed block 5 movably abuts against the other end surface of the motor housing; when the height adjustment block 3 moves up and down, it can drive the motor housing to move up and down.

[0033] The movable plate 2 is movably connected to the mounting seat 1, and the height adjustment block 3 is arranged on the upper end surface of the movable plate 2. The upper end of the height adjustment block 3 movably abuts against the side surface of the motor housing, so when the movable plate 2 moves laterally, it can drive the motor housing to move laterally, thereby achieving the purpose of driving the motor housing to move closer to the positioning component. When the motor housing is placed on the height adjustment block 3, the first fixed block 4 and the second fixed block 5 respectively abut against the two ends of the motor housing, so that it can be ensured that when the movable plate 2 moves, the motor housing can move simultaneously with the movable plate 2, and the motor housing will not slide out of the movable plate 2 due to inertia, thereby ensuring that the motor housing will not be damaged during the movement.

[0034] The height adjustment block 3 is movably arranged on the movable plate 2. When the height adjustment block 3 moves up and down, it can drive the motor housing to move up and down, thereby adjusting the longitudinal position of the motor housing so that the motor housing can remain level with the positioning component, thereby facilitating the positioning of the motor housing.

[0035] The upper end of the movable plate 2 is threadedly connected with a stud 6, and the upper end of the stud 6 is movably inserted on the height adjustment block 3. An adjusting nut 7 is provided on the stud 6, and the adjusting nut 7 movably rests against the end face of the height adjustment block 3; when the adjusting nut 7 is turned clockwise or counterclockwise, the height adjustment block 3 can be driven to move upward or downward.

[0036] The adjusting nut 7 is threadedly connected to the stud 6, and the height adjusting plate abuts against the adjusting nut 7. When the adjusting nut 7 is turned, the relative positions of the adjusting nut 7 and the stud 6 will change, thereby being able to lower or increase the height of the height adjusting block 3. Because the motor housing abuts against the height adjusting block 3, the height of the motor housing can be changed when the height of the height adjusting block 3 changes, thereby achieving the height adjustment of the motor housing, so that the motor housing and the positioning assembly are in a horizontal position.

[0037] A slider 9 is disposed on the lower end surface of the movable plate 2 , a slide rail 8 is disposed on the upper end of the mounting seat 1 , and the slider 9 is movably connected to the slide rail 8 .

[0038] The slider 9 is movably connected to the slide rail 8 , so that the moving plate 2 can move along the route of the slide rail 8 .

[0039] The positioning assembly includes: a positioning plate 10, which is longitudinally arranged on the mounting seat 1, and a positioning column 20, an abutment block 21 and a clamping cylinder 11 are sequentially arranged on the positioning plate 10; when the moving plate 2 drives the motor housing to move toward the positioning plate 10, the positioning column 20 can be inserted into the motor housing, the abutment block 21 can abut against the end face of the motor housing, and the clamping cylinder 11 can clamp the end of the motor housing.

[0040] The positioning column 20 and the abutment block 21 are arranged on the positioning plate 10. When the moving plate 2 drives the motor housing to move toward the positioning plate 10, the end of the motor housing can abut against the abutment block 21, that is, the abutment block 21 can limit the moving distance of the motor housing. The positioning column 20 can be inserted into the motor housing to play a role in positioning the motor housing. When the positioning of the motor housing is completed, the clamping cylinder 11 clamps the end of the motor housing so that the motor housing abuts against the abutment block 21, thereby achieving the purpose of positioning one end of the motor housing.

[0041] A rotating block 12 is disposed at the upper end of the clamping cylinder 11 , and one end of the rotating block 12 is located above the abutting block 21 and abuts against the motor housing.

[0042] When the clamping cylinder 11 is extended or retracted, it can drive the rotating block 12 to rotate. When the rotating block 12 rotates, one end of the rotating block 12 can approach or move away from the end of the motor housing. When one end of the rotating block 12 approaches the end of the motor housing, one end of the rotating block 12 presses tightly against the end of the motor housing. At this time, the motor housing is pressed tightly against the abutment block 21.

[0043] The clamping assembly includes: a connecting plate 13, which is arranged on the mounting seat 1; a clamping plate 14, which is movably connected to the connecting plate 13, and the lower end of the clamping plate 14 is movably connected to the slide rail 8. An insertion disk 15 and a plurality of clamping columns 16 are arranged on the clamping plate 14, and the clamping columns 16 are evenly arranged around the periphery of the insertion disk 15 and are movably connected to the clamping plate 14; when the clamping plate 14 moves toward the motor housing, it can drive the insertion disk 15 to be inserted into the motor housing and each clamping column 16 can press against the end of the motor housing.

[0044] The lower end of the clamping plate 14 is movably connected to the slide rail 8. When the motor housing is placed on the support assembly, the clamping plate 14 moves away from the positioning assembly, thereby increasing the distance between the clamping assembly and the positioning assembly, ensuring that the motor housing can be smoothly placed on the support assembly. After the motor housing is positioned, the clamping plate 14 drives the insertion disk 15 and the clamping column 16 to move toward the motor housing, and then the insertion disk 15 can be inserted into the motor housing, thereby ensuring that the inserted end of the motor housing is in the correct position. Under the joint action of the insertion disk 15 and the positioning column 20, the specific positions of the two ends of the motor housing can be determined, thereby determining the specific position of the motor housing.

[0045] After the insertion disk 15 is inserted into the motor housing, the clamping plate 14 continues to move forward. At this time, the clamping column 16 can abut against the end face of the motor housing, and the clamping plate 14 continues to provide a forward thrust for the clamping column 16, so that the clamping column 16 can abut against the end face of the motor housing, and the other end face of the motor housing can abut against the abutment block 21, thereby clamping the motor housing.

[0046] A plurality of expansion oil cylinders 17 are evenly arranged on the insertion plate 15; when the insertion plate 15 is inserted into the motor housing, one end of each expansion oil cylinder 17 is pressed against the inner wall of the motor housing.

[0047] When the insert plate 15 is inserted into the motor housing, one end of the expansion cylinder 17 is pressed against the inner wall of the motor housing, thereby further clamping the motor housing to ensure that no angular deviation occurs during the processing of the motor housing.

[0048] A clamping spring 18 is sleeved on each clamping column 16 , and one end of each clamping spring 18 abuts against the clamping plate 14 .

[0049] When the clamping plate 14 pushes the clamping column 16 against the end surface of the motor housing, the clamping spring 18 can be squeezed and contracted to prevent the clamping column 16 from causing damage to the end surface of the motor housing due to excessive thrust.

[0050] A moving cylinder 19 is inserted on the connecting plate 13 , and one end of the moving cylinder 19 is connected to the clamping plate 14 .

[0051] The moving cylinder 19 is disposed on the connecting plate 13 and one end of the moving cylinder 19 is connected to the clamping plate 14 , so that when the moving cylinder 19 is extended or retracted, it can drive the clamping plate 14 to slide on the slide rail 8 .

[0052] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the scope defined by the spirit of the present invention.
