Description

Technical Field

[0001] The utility model relates to the technical field of spline detection of rubber suction cup components, in particular to an automatic spline detection mechanism for rubber suction cup components. Background Art

[0002] The rubber suction cup component is an important component of the automobile clutch. The rubber suction cup component is composed of a rubber component, a suction cup component, a wheel hub component, rivets and gaskets. The suction cup component and the wheel hub component are riveted to the rubber component by rivets, and there is a spline mechanism in the center of the wheel hub component. The spline in the rubber suction cup component is a key part for connecting and transmitting power. Its accuracy and quality directly affect the stability and reliability of the entire mechanical system. Therefore, it is very important to accurately and efficiently detect the splines of the rubber suction cup component.

[0003] In the production process of rubber suction cup parts, it is necessary to detect and process their splines. The Chinese utility model patent with the announcement number CN209541644U discloses an automatic detection device for the splines of rubber suction cup parts, including a driving mechanism, a detection mechanism, a detection sliding seat, and a base. A column is provided on the base, and a buffer positioning mechanism is provided on the base. The driving mechanism is arranged on the column. The detection mechanism includes a second motor and a spline detection rod. The second motor is fixed on the detection sliding seat. The rotating shaft of the second motor is fixedly connected to the spline detection rod through a pressure sensor. The driving mechanism drives the detection sliding seat to move in the vertical direction. The utility model only needs to cooperate with a manipulator to realize the automatic detection of the splines of the rubber suction cup parts, thereby reducing manpower input and improving product detection efficiency.

[0004] However, during the use of the utility model, since different splines have different models and sizes, the same spline detection rod cannot be used for different splines. At the same time, it is inconvenient to replace the spline detection rod, which leads to certain limitations of the device and cannot meet production needs. Therefore, a rubber suction cup component spline automatic detection mechanism is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an automatic spline detection mechanism for a rubber suction cup component, which has the advantage of easy replacement of the spline detection rod, and solves the problem that the same spline detection rod cannot be used for different splines due to the different models and sizes of different splines, and it is inconvenient to replace the spline detection rod, which leads to certain limitations of the device and the inability to meet production needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rubber suction cup component spline automatic detection mechanism, comprising a base and a support frame fixedly connected to the top of the base, a lifting platform is arranged directly above the support frame, a disassembly structure is arranged on the side of the lifting platform close to the support frame, and a clamping and positioning mechanism extending to the top of the support frame is arranged inside the support frame to fix the spline;

[0007] The disassembly and assembly structure comprises a mounting sleeve rotatably connected to a side of the lifting platform close to the support frame, an insertion rod extending into the interior of the mounting sleeve is arranged at the bottom of the mounting sleeve, a return spring is fixedly connected to the interior of the insertion rod, and one end of the return spring is fixedly connected to an elastic block extending to the outside of the mounting sleeve;

[0009] Furthermore, the number of the reset spring and the number of the elastic block are both two, the two reset springs are symmetrically distributed inside the insertion rod, and a clamping hole matched with the elastic block is opened inside the mounting sleeve.

[0010] Furthermore, one end of the insertion rod close to the support frame is fixedly connected to an external spline shaft, and a driving motor for driving the mounting sleeve is fixedly installed on the top of the lifting platform.

[0011] Furthermore, a connecting rod is fixedly connected between the clamping block and the second hinged member, and a movable groove adapted to the connecting rod is provided inside the support frame.

[0012] Furthermore, the number of the clamping blocks is four, and the four clamping blocks are evenly distributed on the upper surface of the support frame, and the opposite sides of the four clamping blocks are all arc-shaped.

[0013] Furthermore, a support box is fixedly connected to the back side of the top of the base, a servo motor is fixedly installed on the top of the support box, an adjusting screw extending to the inside of the support box is fixedly connected to the output shaft of the servo motor, and a threaded sleeve is connected to the external thread of the adjusting screw.

[0015] Furthermore, a limiting block extending into the interior of the support box is fixedly connected to a side of the threaded sleeve away from the lifting platform, and a limiting groove matched with the limiting block is provided on the inner wall of the support box.

[0016] Compared with the prior art, the utility model provides a rubber suction cup component spline automatic detection mechanism, which has the following beneficial effects:

[0017] 1. The automatic detection mechanism of the spline of the rubber suction cup component is provided with a reset spring and an elastic block, so that the elastic block can be elastically displaced. When the insertion rod is inserted into the installation sleeve, the installation sleeve will squeeze the elastic block, and then due to the effect of the card hole, the elastic block will be ejected, thereby completing the installation of the insertion rod. Otherwise, the elastic block can be squeezed to disassemble the insertion rod, which is convenient for the staff to replace different external spline shafts according to the spline model, thereby improving the application range of the device.

[0018] 2. The automatic detection mechanism of the spline of the rubber suction cup component drives the connection plate to move up and down by setting a telescopic cylinder, so that the connecting rod drives the first hinge to move and drives the hinge rod to rotate at the same time, thereby being able to drive the four clamping blocks to move at the same time, so as to facilitate the clamping and fixing of the spline and avoid the displacement of the spline during detection. This solves the problem that the same spline detection rod cannot be used for different splines due to the different models and sizes of splines, and it is inconvenient to replace the spline detection rod, which leads to certain limitations of the device and cannot meet production needs.

There are four clamping blocks 13, and the four clamping blocks 13 are evenly distributed on the upper surface of the support frame 2, and the opposite sides of the four clamping blocks 13 are all arc-shaped.
