Description

Technical Field

[0001] This utility model relates to the field of stator rubber ring calibration, and more particularly to a stator rubber ring calibration device. Background Technology

[0002] like Figure 16 As shown, Figure 16 It is a stator produced according to customer requirements. This stator consists of two parts: an iron core and plastic rings. There are two plastic rings, an upper plastic ring and a lower plastic ring, which are respectively fitted onto the upper and lower ends of the iron core.

[0003] Because injection molding has low precision, the eccentricity of the rubber ring is large. The larger the eccentricity, the flatter the shape of the rubber ring, which leads to a mismatch between the rubber ring and the iron core, making it impossible for the two to be installed smoothly. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a stator rubber ring correction device to solve the problem of excessive centrifugal force of the rubber ring.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a stator rubber ring correction device, characterized in that it comprises:

[0006] A positioning platform is used to provide a positioning area for the rubber ring;

[0007] The calibration mechanism includes a cam disk and multiple followers. The cam disk has multiple cam grooves with curved profiles. One end of the follower is a pressing end, and the other end is embedded in the cam groove. The cam grooves are symmetrically distributed along the same direction away from the center of the positioning platform, so that the multiple followers form a rigid constraint on the rubber ring along the cam groove trajectory.

[0008] The beneficial effects of this utility model are:

[0009] The correction mechanism used in this invention consists of a cam disk and multiple driven members. The offset setting of the cam groove allows the multiple driven members to constrain the enclosed rubber ring in a synchronous manner, thereby achieving the purpose of correction and further reducing the eccentricity of the entire rubber ring. In addition, this synchronous form can also prevent the rubber ring from undergoing accelerated deformation.

[0010] Regarding the symmetrical distribution of the cam groove trajectory along the same direction away from the center of the positioning platform, specifically, the distribution of the cam groove on the cam disk is 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 seen that the two endpoints in the cam groove are distributed on arcs with different eccentricities. Therefore, the follower can be driven to reciprocate according to the expected law through the contour.

[0011] The aforementioned cam disk has a ring structure and is fitted onto the positioning platform. The cam disk and the positioning platform are parallel. During calibration, the surfaces of the follower and the rubber ring that contact each other are 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 that adapts to the outer circumference of the rubber ring. Specifically, this shape is arc-shaped. The 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 equipped with a guide block, and the rubber ring has a pre-reserved opening through which it can pass. During the calibration process, the guide block is inserted into the opening. This is to prevent the rubber ring from suddenly breaking free of the constraint and rebounding and being ejected due to deformation under force during calibration.

[0014] Above the cam disk is a guide disk, which is also a ring structure. The guide disk has guide grooves adapted to the follower, and these grooves have a depth sufficient for the follower to move linearly. The guide disk is fixed; therefore, as the cam disk rotates, the follower, constrained by the guide grooves, moves linearly forward or backward. Specifically, a fixed seat is provided outside the cam disk to support the guide disk.

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

[0016] The bearing mounting base contains a second bearing, which is fitted onto the positioning platform.

[0017] In this specific embodiment, a fixed block is also included, and a bearing mounting seat is disposed on the fixed block. A pair of limit sensors are also provided on the fixed block, with the sensing ends of the limit sensors facing each other. A buffer block is provided on the outer wall of the fixed block between the two sensing ends. The extension and retraction of the output end of the drive cylinder will cause the bearing mounting seat to achieve forward and reverse rotation. In order to constrain the rotation amplitude of the cam disc, after the buffer block contacts either sensing end, the drive cylinder is stopped by the upper computer to avoid irreversible rigid damage between the cam disc and the second bearing.

[0034] Please see Figure 1-16 As shown, a stator rubber ring 2 calibration device is characterized by comprising:

[0035] Positioning platform 8 is used to provide a positioning area to rubber ring 2;

[0036] The correction mechanism includes a cam disk 100 and multiple followers 101. The cam disk 100 is provided with multiple cam grooves 100-a with curved contours. One end of the follower 101 is a pressing 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 away from the center of the positioning platform 8, so that the multiple followers 101 form a rigid constraint on the rubber ring 2 along the trajectory of the cam groove 100-a.

[0037] The beneficial effects of this utility model are:

[0038] The correction mechanism used in this utility model consists of a cam disk 100 and multiple followers 101. The offset setting of the cam groove 100-a allows the multiple followers 101 to constrain the enclosed rubber ring 2 in a synchronous manner, thereby achieving the purpose of correction and further reducing the eccentricity of the entire rubber ring 2. In addition, this synchronous form can also prevent the rubber ring 2 from undergoing accelerated deformation.

[0039] Regarding the symmetrical distribution of the trajectory of cam groove 100-a off from the center of the positioning platform 8 in the same direction, specifically, the distribution of cam groove 100-a on cam disk 100 is such that one end is close to the inner ring surface of cam disk 100, and the other end is close to the outer ring surface of cam disk 100 (from the top view, the offset of cam groove 100-a rotates counterclockwise on cam disk 100). Thus, it can be seen that the two endpoints of cam groove 100-a are distributed on arcs with different eccentricities. Therefore, the follower 101 can be driven to reciprocate according to the expected law through the contour.

[0040] The aforementioned cam disk 100 has a ring structure and is fitted onto the positioning platform 8. The cam disk 100 and the positioning platform 8 are parallel. During calibration, the surfaces of the follower 101 and the rubber ring 2 are 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 that adapts to the outer peripheral surface of the rubber ring 2. Specifically, this shape is arc-shaped. The end of the follower 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. The rubber ring 2 has a pre-reserved opening through which it can pass. During the calibration process, the guide block 101-b is inserted into the opening. This is to prevent the rubber ring 2 from suddenly breaking free from the constraint and rebounding and being ejected due to deformation under force during calibration.

[0043] Above the cam disk 100, a guide disk 103 is also provided. The guide disk 103 is also a ring structure, and it has a guide groove 103-a adapted to the follower 101. The guide groove 103-a has a depth for the follower 101 to move linearly. 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 linear forward or backward movements. Specifically, outside the cam disk 100, a fixed seat 104 is also provided to support the guide disk 103.

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

[0045] The bearing mounting base 42 contains a second bearing, which is fitted onto the positioning platform 8.

[0046] In this specific embodiment, a fixed block 5 is also included, and a bearing mounting seat 42 is disposed on the fixed block 5. A pair of limit sensors 6 are also provided on the fixed block 5. The sensing ends of the limit sensors 6 are opposite to each other. A buffer block 7 is provided on the outer wall of the fixed block 5 between the two sensing ends. The extension and retraction of the output end of the drive cylinder 44 will drive the bearing mounting seat 42 to achieve forward and reverse rotation. In order to constrain the rotation amplitude of the cam disk 100, after the buffer block 7 contacts either sensing end, the drive cylinder 44 is stopped from extending and retracting by the host computer to avoid irreversible rigid damage between the cam disk 100 and the second bearing.

[0047] The positioning platform 8 includes a positioning base 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 base 81, and 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, and 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 one 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 base 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 base 81. The positioning base 81 has corresponding positioning ports 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 immediately carried out. For this, first, the iron core 3 is placed, and then the rubber ring 2 is placed on its upper end. After the stator rubber ring 2 calibration mechanism of the present utility model 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 utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model should fall within the protection scope determined by the claims of the present utility model.
