Description

Technical Field

[0001] The utility model relates to the technical field of motor housing processing, in particular to a fixing device for motor housing processing. Background Art

[0002] The motor is a basic equipment in modern industrial production and a type of general mechanical equipment. The motor housing is a shell structure used to accommodate and install the motor rotor and stator related structures. During actual processing, it needs to be fixed by a fixing device, and the outer surface needs to be processed using related equipment. Most existing fixing devices use a clamp to clamp the outer side of the motor housing for processing. However, the processing of the motor housing includes internal processing and external processing. When the clamp is clamping the motor housing, it will hinder the external processing of the motor housing. Therefore, a fixing device for motor housing processing is proposed. When the motor housing is processed internally and externally, two different clamps are used to clamp and fix the motor housing, respectively, to avoid the clamp affecting the processing. Utility Model Content

There are multiple connecting rods, and the multiple connecting rods are movably connected to the slider and the fixed block.

[0009] By adopting the above technical solution, the slider moves downward on the outside of the screw rod, and then the slider drives the connecting rod to expand outward, so that the two second chucks can clamp and fix the motor housing from the inside to the outside, and then cooperate with the rotation of the first turntable to facilitate the staff to process all directions of the outside of the motor housing.

[0010] Specifically, a first electric cylinder is fixedly installed inside the workbench, the output end of the first electric cylinder is fixedly connected to the bottom end of the first piston push rod, and the top end of the first piston push rod is fixedly connected to the bottom center of the mounting block.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] In order to clamp and fix the motor housing with two different fixtures during internal and external processing of the motor housing, thereby avoiding the fixture affecting the processing, as an embodiment of the present invention, Figures 1-4 As shown, the fixing device for machining a motor housing according to the present invention comprises a workbench 1, a second turntable 5 is rotatably mounted on the top of the workbench 1, a second electric cylinder 9 is fixedly mounted on the top of the second turntable 5, and the second electric cylinder 9 is provided at two opposite locations, the output ends of the two second electric cylinders 9 are fixedly connected to one end of a second piston push rod 8, and the ends of the two second piston push rods 8 that are close to each other are fixedly connected to one side of a first chuck 7;

[0025] A mounting block 6 is movably mounted at the center of the workbench 1 , a first turntable 2 is rotatably mounted at the center of the mounting block 6 , and a fixing rod 15 is fixedly mounted at the top center of the first turntable 2 .

[0026] During use, the two second electric cylinders 9 are started by an external power supply. The start of the two second electric cylinders 9 will drive the two second piston push rods 8 to approach each other, and then the two first clamps 7 can be brought close to each other. The first clamps 7 that are close to each other can clamp and fix the motor housing at the center of the second turntable 5, and the second turntable 5 can be rotated, and then the motor housing is rotated, which is convenient for the staff to process the outside of the motor housing.

[0027] For example, Figure 1-4 As shown, the present invention further includes: a fixed block 16 is fixedly sleeved on the outer side of the fixed rod 15; a screw rod 12 is rotatably connected to the top end of the fixed rod 15; and a slider 14 is movably sleeved on the outer side of the screw rod 12.

[0028] During use, when the outside of the motor housing needs to be processed, the motor housing is vertically sleeved on the outside of the screw rod 12, and the slider 14 outside the screw rod 12 is moved downward by rotating the screw rod 12.

[0029] For example, Figure 1-4 As shown, the new use model also includes a second chuck 10 movably connected between the slider 14 and the fixed block 16 via a connecting rod 13, the second chuck 10 is relatively provided at two locations, and there are multiple connecting rods 13, and the multiple connecting rods 13 are movably connected to the slider 14 and the fixed block 16.

[0030] During use, the downward movement of the slider 14 can expand the connecting rod 13 connecting the slider 14 to the outside of the fixed block 16 outward. The outward expansion of the connecting rod 13 will push the two second chucks 10 outward, thereby clamping and fixing the motor housing on the outside of the screw rod 12 from the inside to the outside. The first turntable 2 can be rotated to drive the screw rod 12 and the motor housing to rotate, making it convenient for the staff to process the outside of the motor housing.

[0032] During use, when the interior of the motor housing needs to be processed, the motor housing is placed vertically at the center of the second turntable 5. First, the first electric cylinder 3 is started by an external power supply. The first electric cylinder 3 will drive the first piston push rod 11 to move downward, and then drive the mounting block 6 to move downward.

[0033] For example, Figure 1-4 As shown, the present invention further includes that a storage cavity 4 is provided inside the workbench 1 , and the storage cavity 4 is used for placing and storing the mounting block 6 .

[0034] When in use, the mounting block 6 and the screw rod 12 can be completely received in the receiving cavity 4 to avoid interfering with the internal processing of the motor housing.

[0035] When the utility model is in use, when it is necessary to process the outside of the motor housing, the motor housing is vertically sleeved on the outside of the screw rod 12, and the slider 14 on the outside of the screw rod 12 is moved downward by rotating the screw rod 12, so that the connecting rod 13 connecting the slider 14 and the outside of the fixing block 16 can be expanded outward, and the outward expansion of the connecting rod 13 will push the two second clamps 10 outward, so that the motor housing sleeved on the outside of the screw rod 12 can be clamped and fixed from the inside to the outside, and the first turntable 2 can be rotated to drive the screw rod 12 and the motor housing to rotate, so that the staff can conveniently process the outside of the motor housing;

[0036] When it is necessary to process the interior of the motor housing, the motor housing is placed vertically at the center of the second turntable 5. First, the first electric cylinder 3 is started by an external power supply. The first electric cylinder 3 will drive the first piston push rod 11 to move downward, and then drive the mounting block 6 to move downward, so that the mounting block 6 and the screw rod 12 are all stored in the storage cavity 4 to avoid interference with the internal processing of the motor housing. Then, the two second electric cylinders 9 are started by an external power supply. The start of the two second electric cylinders 9 will drive the two second piston push rods 8 to approach each other, and then the two first chucks 7 can be brought close to each other. The first chucks 7 close to each other can clamp and fix the motor housing at the center of the second turntable 5, and the second turntable 5 can be rotated and then the motor housing is rotated, which is convenient for the staff to process the outside of the motor housing.
