Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to an internal support clamp for processing motor cylinder parts. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It can be divided into DC motors and AC motors. The working principle of a DC generator is to convert the alternating electromotive force induced in the armature coil into a DC electromotive force when it is led out from the brush end through the commutation action of the commutator and the brush.

[0003] When machining the cylindrical parts of motors, it is usually necessary to machine the outer surface. Commonly used positioning fixtures usually clamp and position the outer surface directly, but the fixtures often affect the normal machining of the outer surface and have poor use effects. Utility Model Content

[0006] The internal support mechanism includes a motor, a first gear, a second gear, a driving shaft, a positioning plate, a positioning part, an adjusting shaft and a toggle part. The first gear is fixedly mounted at the output end of the motor, and the driving shaft rotates on the supporting seat through a bearing. The second gear is fixedly mounted at one end of the driving shaft and meshes with the first gear for transmission. The positioning plate is fixed to the supporting seat through a fixing rod. The toggle part is rotatably installed inside the positioning plate and fixed to the other end of the driving shaft. The adjusting shaft is a plurality of groups arranged around the edge of the toggle part and extending out of the positioning plate. The positioning part is fixed at one end of the adjusting shaft extending out of the positioning plate.

[0007] By adopting the technical solution, it is convenient to clamp motor cylindrical parts of different sizes from the inside, so as to facilitate the external processing thereof.

[0012] The middle part of the toggle part is arranged in a circular ring structure, the edge of the toggle part is arranged in a fan-shaped structure, and four groups are arranged around it at equal angles.

[0013] By adopting the above technical solution, the adjusting shaft rod can be driven to push the positioning part to support the inner part of the motor cylinder.

[0014] The adjusting shaft rods are arranged in four groups and are arranged one by one between the fan-shaped structures at the edge of the toggle part. One end of the adjusting shaft rod close to the toggle part is arranged in a hemispherical structure, and its diameter is larger than the diameter of the other part of the adjusting shaft rod.

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] Reference Figure 1-2 , an internal support fixture for machining motor cylindrical parts, comprising a workbench 1, two sets of support seats 2 are installed on the workbench 1, and the two sets of support seats 2 are both installed with internal support mechanisms;

[0025] The inner support mechanism includes a motor 5, a first gear 6, a second gear 7, a drive shaft 8, a positioning plate 9, a positioning part 11, an adjusting shaft rod 12 and a toggle part 13. The first gear 6 is fixedly mounted at the output end of the motor 5. The drive shaft 8 rotates on the support seat 2 through a bearing. The second gear 7 is fixedly mounted on one end of the drive shaft 8 and meshes with the first gear 6 for transmission. The positioning plate 9 is fixed to the support seat 2 through a fixing rod 10. The toggle part 13 is rotatably mounted inside the positioning plate 9 and fixed to the other end of the drive shaft 8. The adjusting shaft rod 12 is a plurality of groups arranged around the edge of the toggle part 13 and extending out of the positioning plate 9. The positioning part 11 is fixed at one end of the adjusting shaft rod 12 extending out of the positioning plate 9.

[0026] The motor cylindrical part can be placed between the two groups of support seats 2, and the driving cylinder 4 drives the movable group of support seats 2 to move to a suitable position along the slide rail 3. At this time, the two groups of motors 5 can be driven to rotate the second gear 7 through the first gear 6, and the second gear 7 drives the toggle part 13 to rotate through the driving shaft 8. When the toggle part 13 rotates, it pushes the adjusting shaft rod 12 through its side, and the adjusting shaft rod 12 can support the end of the motor cylindrical part from the inside through the positioning part 11, so that the motor cylindrical part can be internally supported and positioned;

[0027] The inner support mechanisms on the two groups of support seats 2 are arranged relatively, and the motors 5 on the inner support mechanisms are all fixed on one end face of the support seat 2. The second gear 7, the drive shaft 8 and the positioning plate 9 are all arranged coaxially. The positioning plate 9 is fixed on the support seat 2 by three groups of fixing rods 10. The three groups of fixing rods 10 are arranged around the outer side of the drive shaft 8, so as to position the positioning plate 9. When the drive shaft 8 rotates, the middle part of the toggle part 13 is arranged in a circular ring structure, and its edge is arranged in a fan-shaped structure, and four groups are arranged around it at equal angles, which can synchronously drive the toggle part 13 to rotate, and the toggle part 13 gradually pushes the adjustment shaft rod 12 through its arc-shaped surface, and the surface of the positioning part 11 contacting the inner side of the motor cylindrical part is an arc-shaped structure, so that the adjusting shaft rod 12 pushes the positioning part 11 to adapt the arc inner support to the motor cylindrical part.

[0028] The two groups of support seats 2 are one group fixed on the workbench 1, and the other group slides on the slide rail 3 fixed on the workbench 1; the workbench 1 is also equipped with a cylinder 4 for driving the movable group of support seats 2 to slide along the slide rail 3, which can drive the cylinder 4 to push the movable group of support seats 2 to a suitable position, and the motor cylindrical parts are internally supported by the internal support mechanism, saving manpower for pushing.

[0029] The adjusting shaft rods 12 are arranged in four groups and are arranged one by one between the fan-shaped structures at the edge of the toggle part 13. One end of the adjusting shaft rod 12 close to the toggle part 13 is arranged as a hemispherical structure, and its diameter is larger than the diameter of the other part of the adjusting shaft rod 12.

[0030] The bottom of the adjusting shaft 12 is a hemispherical structure, which can prevent the adjusting shaft 12 from escaping from the positioning disk 9. The hole opened on the side of the positioning disk 9 is adapted to the cylindrical part of the adjusting shaft 12, so that the adjusting shaft 12 can be normally extended and retracted in the positioning disk 9.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
