Description

Technical Field

[0001] The present invention relates to the field of stator rubber ring correction, and particularly to a stator rubber ring correction device. Background Art

[0002] As Figure 16 shown Figure 16 is a stator produced according to customer requirements. This stator consists of two parts. One part is the iron core, and the other part is a rubber ring made of plastic. There are two rubber rings, namely an upper rubber ring and a lower rubber ring, which are respectively sleeved on the upper and lower ends of the iron core.

[0003] Due to the low precision of injection molding, the eccentricity of the rubber ring is large. The larger the eccentricity, the flatter the shape of the rubber ring, which leads to the problem that the rubber ring does not match the iron core, and the two cannot be installed smoothly. Summary of the Invention

[0004] To solve the above problems, the present invention provides a stator rubber ring correction device for solving the problem of excessive eccentricity of the rubber ring.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a stator rubber ring correction device, characterized by comprising:

[0006] A positioning platform for providing a positioning area for the rubber ring;

[0007] A correction mechanism, the correction mechanism comprising a cam disk and a plurality of follower members. The cam disk is provided with a plurality of cam grooves with curved profiles. One end of the follower member is an extrusion end, and the other end is embedded in the cam groove. The trajectories of the cam grooves are symmetrically distributed along the same direction deviating from the center of the positioning platform, so that the plurality of follower members form a rigid constraint on the rubber ring along the trajectories of the cam grooves.

[0008] Advantages of the Present Invention:

[0009] The correction mechanism used in the present invention is composed of a cam disk and a plurality of follower members. Among them, the offset setting of the cam grooves enables the plurality of follower members to constrain the surrounded rubber ring in a synchronous manner, so as to achieve the purpose of correction and further reduce the eccentricity of the entire rubber ring; in addition, this synchronous form can also prevent the rubber ring from being deformed more severely.

[0010] Regarding the symmetric distribution of the trajectories of the cam grooves along the same direction deviating from the center of the positioning platform, specifically, the cam grooves are distributed on the cam disk such that one end is close to the inner ring surface of the cam disk and the other end is close to the outer ring surface of the cam disk. Thus, it can be obtained that the two end points in the cam groove are distributed on arcs with different eccentricities. Therefore, the contour can be used to push the follower member to perform reciprocating motion according to the expected law.

[0011] The above-mentioned cam disk is of an annular structure. The cam disk is sleeved on the positioning platform, and the cam disk is parallel to the positioning platform. During calibration, the surfaces of the follower in contact with the rubber ring are all on the same horizontal plane, which makes the distribution of the calibration force on the rubber ring uniform.

[0012] The extrusion end has a shape adapted to the outer peripheral surface of the rubber ring, and this shape is specifically an arc. One end of the follower embedded in the cam groove is provided with a first bearing. The purpose of using the first bearing is to reduce the friction generated by mutual contact and improve the overall stability of use.

[0013] The extrusion end is also provided with a guide block, and an opening through which the guide block can pass is reserved on the rubber ring. During the calibration process, the guide block penetrates into the opening, which is to prevent the rubber ring from suddenly breaking away from the restraint due to force deformation and rebounding and projecting during calibration.

[0014] A guide disk is also provided above the cam disk. The guide disk is also of an annular structure. The guide disk is provided with a guide groove adapted to the follower, and the guide groove has a depth for the linear movement of the follower. The guide disk is fixed. Therefore, under the rotation of the cam disk, the follower is constrained by the guide groove and makes a linear forward or backward movement. Specifically, outside the cam disk, there is also a fixed seat for supporting the guide disk.

[0015] It also includes a turntable fixed seat, a bearing mounting seat, a swing arm, and a driving cylinder. The turntable fixed seat is arranged on the bearing fixed seat, the cam disk is arranged on the turntable fixed seat, one end of the swing arm is connected to the outer wall of the bearing mounting seat, and the other end of the swing arm is hinged to the output end of the driving cylinder. Under the action of the driving cylinder, the bearing mounting seat will rotate, and then drive the cam disk to rotate in sequence through the turntable fixed seat.

[0016] A second bearing is arranged inside the bearing mounting seat, and the second bearing is sleeved on the positioning platform.

[0017] In this specific embodiment, it also includes a fixed block. The bearing mounting seat is arranged on the fixed block. A pair of limit sensors are also arranged on the fixed block. The sensing ends of the limit sensors face each other. A buffer block is arranged on the outer wall of the fixed block between the two sensing ends. The telescopic movement of the output end of the driving cylinder will drive the bearing mounting seat to rotate forward and backward. In order to restrict the rotation amplitude of the cam disk, after the buffer block touches any one of the sensing ends, the driving cylinder is controlled by the upper computer to stop telescoping to avoid irreversible rigid damage to the cam disk and the second bearing.

[0034] Please refer to Figures 1 - 16 shown in the figure, a stator rubber ring 2 calibration device, characterized in that it comprises:

[0035] A positioning platform 8 for providing a positioning area for the rubber ring 2;

[0036] Calibration mechanism, the calibration mechanism includes a cam disk 100 and a plurality of follower members 101. The cam disk 100 is provided with a plurality of cam grooves 100-a having a curved profile. One end of the follower member 101 is an extrusion end, and the other end is embedded in the cam groove 100-a. The trajectory of the cam groove 100-a is symmetrically distributed along the same direction deviating from the center of the positioning platform 8, so that the plurality of follower members 101 form a rigid constraint on the rubber ring 2 along the trajectory of the cam groove 100-a.

[0037] Advantages of the present invention:

[0038] The calibration mechanism used in the present invention is composed of a cam disk 100 and a plurality of follower members 101. Among them, the offset setting of the cam groove 100-a enables the plurality of follower members 101 to constrain the surrounded rubber ring 2 in a synchronous manner, so as to achieve the purpose of calibration and further reduce the eccentricity of the entire rubber ring 2. In addition, this synchronous form can also prevent the rubber ring 2 from experiencing an aggravated deformation.

[0039] Regarding the symmetric distribution of the trajectory of the cam groove 100-a along the same direction deviating from the center of the positioning platform 8, specifically, the cam grooves 100-a are distributed on the cam disk 100 such that one end is close to the inner ring surface of the cam disk 100 and the other end is close to the outer ring surface of the cam disk 100 (from a top view, the offset of the cam groove 100-a rotates counterclockwise on the cam disk 100). Thus, it can be obtained that the two end points in the cam groove 100-a are distributed on arcs with different eccentricities. Therefore, the contour can also be used to push the follower member 101 to perform reciprocating motion according to the expected law.

[0040] The above-mentioned cam disk 100 is of an annular structure. The cam disk 100 is sleeved on the positioning platform 8, and the cam disk 100 is parallel to the positioning platform 8. During calibration, the surfaces of the follower members 101 in contact with the rubber ring 2 are all on the same horizontal plane, which makes the distribution of the calibration force on the rubber ring 2 uniform.

[0041] The extrusion end 101-a has a shape adapted to the outer peripheral surface of the rubber ring 2, and this shape is specifically an arc. One end of the follower member 101 embedded in the cam groove 100-a is provided with a first bearing 102. The purpose of using the first bearing 102 is to reduce the friction generated by mutual contact and improve the overall stability of use.

[0042] The extrusion end 101-a is also provided with a guide block 101-b, and an opening through which it can pass is reserved on the rubber ring 2. During the calibration process, the guide block 101-b penetrates into the opening, which is to prevent the rubber ring 2 from suddenly breaking away from the constraint due to force deformation and experiencing a rebound and ejection during calibration.

[0043] Above the cam disk 100, there is also a guide disk 103. The guide disk 103 is also of an annular structure. The guide disk 103 is provided with a guide groove 103-a adapted to the follower 101. The guide groove 103-a has a depth for the linear movement of the follower 101. The guide disk 103 is fixed. Therefore, under the rotation of the cam disk 100, the follower 101 is constrained by the guide groove 103-a and makes a forward or backward linear movement. Specifically, outside the cam disk 100, there is also a fixed seat 104 for supporting the guide disk 103.

[0044] It also includes a turntable fixed seat 41, a bearing mounting seat 42, a swing arm 43, and a driving cylinder 44. The turntable fixed seat 41 is arranged on the bearing fixed seat 42. The cam disk 100 is arranged on the turntable fixed seat 41. One end of the swing arm 43 is connected to the outer wall of the bearing mounting seat 42, and the other end of the swing arm 43 is hinged to the output end of the driving cylinder 44. Under the action of the driving cylinder 44, the bearing mounting seat 42 will rotate, and then drive the cam disk 100 to rotate in sequence through the turntable fixed seat 41.

[0045] Inside the bearing mounting seat 42, there is a second bearing, and the second bearing is sleeved on the positioning platform 8.

[0046] In this specific embodiment, it also includes a fixed block 5. The bearing mounting seat 42 is arranged on the fixed block 5. The fixed block 5 is also provided with a pair of limit sensors 6. The sensing ends of the limit sensors 6 face each other. A buffer block 7 is arranged on the outer wall of the fixed block 5 between the two sensing ends. The telescopic movement of the output end of the driving cylinder 44 will drive the bearing mounting seat 42 to rotate forward and backward. In order to restrict the rotation amplitude of the cam disk 100, after the buffer block 7 touches any one of the sensing ends, the driving cylinder 44 is controlled by the upper computer to stop telescoping, so as to avoid irreversible rigid damage to the cam disk 100 and the second bearing.

[0047] The positioning platform 8 includes a positioning seat 81, a positioning block 82, a spring 83, a spring positioning seat 84, and a pin shaft 85. An assembly groove 81-a is provided on the positioning seat 81. The positioning block 82 is arranged in the assembly groove 81-a. The spring positioning seat 84 is in the shape of a "C". A positioning groove 82-a penetrating the inner and outer surfaces is provided on the positioning block 82. The spring positioning seat 84 is embedded in the positioning groove 82-a and can move within the positioning groove 82-a. Both the pin shaft 85 and the spring 83 are embedded in the spring positioning seat 84. One end of the spring 83 is connected to the pin shaft 85, and the other end of the spring 83 abuts against the inner wall of the spring positioning seat 84. Among them, a limiting portion 84-a is provided on the edge of the open end of the spring positioning seat 84, and the positioning block 82 has a limiting groove 82-b for the limiting portion 84-a to move a certain stroke. The function of the limiting groove 82-b is to prevent the spring positioning seat 84 from detaching from the inner surface of the positioning block 82. The cam disk 100 is sleeved outside the positioning seat 81. Under the action of the spring 83, the pin shaft 85 abuts against the inner surface of the cam disk 100.

[0048] It should be noted that during calibration, both the iron core 3 and the rubber ring 2 are located within the positioning seat 81. The positioning seat 81 has corresponding positioning openings 81-b for the iron core 3 and the rubber ring 2. After the shape of the rubber ring 2 is corrected, the fitting between the rubber ring 2 and the iron core 3 can be carried out immediately. For this, first, the iron core 3 is placed, and then the rubber ring 2 is placed on top of it. After the stator rubber ring 2 calibration mechanism of the present invention completes the shape correction of the rubber ring 2, through other equipment, the rubber ring 2 is pressed down, thereby completing the assembly between the rubber ring 2 and the iron core 3.

[0049] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
