The clutch dynamic balance detection fixture described in the present invention has a detection mechanism that is installed one-to-one based on the clutch system of the car. In this way, the clutch detection environment is more in line with reality, which indirectly guarantees the accuracy of the clutch detection results. In addition, the laser pen is used in conjunction with the detection flywheel for detection, and the straightness of the light further guarantees the detection accuracy of the fixture. The light-absorbing strip is made of black material, and the light ring is made of white material. If the light-absorbing strip is irradiated by the laser, the black light reflected by the light-absorbing strip is not easily perceived by the operator. When the laser is shot at the light ring, the light ring can effectively reflect red light. In this way, the operator can more quickly perceive the dynamic balance performance defects of the clutch.

Description

Technical Field

[0001] The present invention relates to the field of detection technology, in particular to a clutch dynamic balance detection fixture. Background Art

[0002] The clutch is a common component in mechanical transmission, which can separate or engage the transmission system at any time;

[0003] Because the clutch is installed between the engine and the transmission, it is an assembly part in the automobile transmission system that is directly connected to the engine. Therefore, the premise for ensuring the safety of automobile driving is to ensure that the clutch can rotate smoothly enough.

[0004] The direct cause of the clutch's dynamic balance is that the clutch's weight is not uniform. Generally speaking, during the operation of the clutch, it is necessary to observe whether the clutch's rotation has excessive vibration to know whether the clutch's dynamic balance performance is qualified.

[0005] The dynamic balancing machines available on the market are the main technical means for detecting the dynamic balance performance of machinery. However, due to the complex structure of the clutch, which is different from that of general mechanical rotors and is complicated to install, general dynamic balancing machines are not suitable for this purpose. In addition, the results of the dynamic balancing machine are presented in the form of electronic data. Although it is accurate enough, the test results are not intuitive enough. Therefore, we propose a fixed tool for clutch dynamic balance detection. Summary of the Invention

[0006] (1) Technical problems solved

[0007] In view of the shortcomings of the existing technology, the present invention provides a clutch dynamic balance detection fixture, which has the advantages of intuitive detection and practical application, and can effectively solve the problems in the background technology.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is: a clutch dynamic balance detection fixture, including a clutch, and also including

[0009] Fixed fixtures installed on both sides of the clutch for dynamic balance performance testing;

[0010] The fixing fixture includes a detection mechanism for fixing the clutch and a laser pen for performing detection in conjunction with the laser pen.

[0011] Preferably, the lower ends of the laser pen and the detection mechanism are provided with a frame for fixing them;

[0012] The detection mechanism includes a detection flywheel that cooperates with the laser pen to perform dynamic balance detection, and a connecting shaft is provided at the middle part of the outer side of the detection flywheel.

[0013] Preferably, the outer wall of the connecting shaft is provided with a support bearing for fixed support, and the lower end of the support bearing is connected to the upper end of the frame. A spline hub is attached to the geometric center of the detection flywheel, and the inner wall of the spline hub is provided with a spline shaft that matches its structure.

[0014] Preferably, a release bearing is provided on the outer wall of the middle section of the spline shaft, and a pressure lever is provided on one side of the outer wall of the outer ring of the release bearing. A support bearing is also provided on the outer wall of the side section of the spline shaft away from the detection flywheel.

[0015] Preferably, the middle section of the pressing lever is provided with a support rod, and the support rod is fixedly connected to one side of a support bearing attached to the spline shaft.

[0016] Preferably, a hydraulic rod is provided at one end of the pressing lever away from the release bearing, and the main body of the hydraulic rod is fixedly connected to the frame.

[0017] Preferably, the detection flywheel includes a flywheel body, and a light ring for cooperating with a laser pen for detection is provided on the outer edge of the flywheel body away from the clutch.

[0018] Preferably, a light absorbing strip is provided in the middle of the light ring, and the width of the light absorbing strip is 1 mm.

[0019] Compared with the prior art, the present invention provides a clutch dynamic balance detection fixture, which has the following beneficial effects:

[0020] The clutch dynamic balance detection fixture has an overall detection mechanism that is designed one-to-one with the vehicle's clutch system, making the clutch detection environment more realistic and indirectly ensuring the accuracy of the clutch detection results. In addition, the laser pen is used in conjunction with the detection flywheel for detection, and the linearity of light further ensures the detection accuracy of the fixture.

[0021] The clutch dynamic balance detection fixture has a detection flywheel, a light-absorbing strip made of black material, and a light ring made of white material. If the light-absorbing strip is irradiated by a laser, the black light reflected by the light-absorbing strip is not easily perceived by the operator. However, when the laser is emitted to the light ring, the light ring can effectively reflect red light, thereby allowing the operator to more quickly detect defects in the dynamic balance performance of the clutch.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0039] In order to address the shortcomings of existing technologies, such as Figure 1 、 2 As shown, the present invention provides a clutch dynamic balance detection fixture, and the clutch 1 and the fixture 2 are detachably connected.

[0040] Specifically, such as Figure 3 As shown, the clutch dynamic balance detection fixture has its main body, the detection mechanism 22 is fixedly connected to the upper end of the frame 23, and the laser pen 21 is fixedly connected to one side of the upper end of the frame 23, and the clutch 1 is connected to the detection mechanism 22.

[0041] It should be noted that the present invention is a fixed tool for clutch dynamic balance detection. Before testing the dynamic balance performance of the clutch 1, the operator first installs the clutch 1 on the detection mechanism 22, and connects the two mechanical input ends of the detection mechanism 22 to the external transmission device, and then turns on the laser pen 21 to perform dynamic balance performance testing.

[0042] Furthermore, Figure 4As shown, the detection mechanism 22 used for the clutch dynamic balance detection fixture has a detection flywheel 221 with a middle portion outside thereof fixedly connected to one end of a connecting shaft 222, and the connecting shaft 222 is fixedly connected to the inner wall of the inner ring of one support bearing 223, a spline shaft 224 is plugged into the inner wall of the inner ring of the other support bearing 223, and a spline section of the spline shaft 224 is plugged into the inner wall of the spline hub located in the middle of the detection flywheel 221;

[0043] The housing of the clutch 1 is fixedly connected to the detection flywheel 221, and the diaphragm spring of the clutch 1 is in contact with the release bearing 225. The mechanical output end of the hydraulic rod 227 is fixedly connected to one end of the pressing lever 226, and the other end of the pressing lever 226 is rotatably connected to the outer wall of the outer ring of the release bearing 225.

[0044] One end of the support rod attached to the middle section of the pressing lever 226 is fixedly connected to one side of one of the support bearings 223 adjacent to the spline shaft 224, and the other end of the pressing lever 226 is rotatably connected to the middle section of the pressing lever 226, and the lower ends of the two support bearings 223 are fixedly connected to the frame 23.

[0045] It should be noted that the present invention is a fixture for clutch dynamic balance detection. By means of the detection mechanism 22, before detecting the dynamic balance performance of the clutch 1, the operator first removes the spline shaft 224, then moves the release bearing 225 apart to place the clutch 1 between the release bearing 225 and the detection flywheel 221, and fixes the housing on which the clutch 1 is based to the inner side of the detection flywheel 221 by fixing screws. After the clutch 1 and the detection flywheel 221 are installed, the release bearing 225 should be fully connected with the clutch 1.

[0046] Then the operator inserts the spline shaft 224 through the separation bearing 225 and connects it to the corresponding support bearing 223 and the spline hub located in the middle of the detection flywheel 221. After the spline shaft 224 is connected, the connecting shaft 222 and the spline shaft 224 can be connected to the external transmission device, and the oil supply port on the hydraulic rod 227 can be connected to the external oil supply device through the oil pipe.

[0047] During the dynamic balance performance test of the clutch 1, the transmission device drives the connecting shaft 222 and the spline shaft 224 to rotate synchronously. At the same time, the operator can control the oil supply device to realize the pressure supply and pressure relief of the hydraulic rod 227.

[0048] When the hydraulic rod 227 is compressed, the output rod on it extends, driving the pressing lever 226 to rotate based on the support rod on it, thereby driving the release bearing 225 to slide inward based on the clutch 1, thereby squeezing the diaphragm spring on the clutch 1;

[0049] In contrast, after the hydraulic rod 227 is depressurized, the output rod thereon retracts and resets, thereby driving the pressing lever 226 to rotate based on the support rod thereon, driving the release bearing 225 to slide outward based on the clutch 1, thereby realizing the closed state of the clutch 1.

[0050] In order to better realize the dynamic balance performance detection of the clutch 1, a solenoid valve can be installed between the hydraulic rod 227 and the oil supply device, and the solenoid valve can be periodically opened and closed to realize the periodic pressure supply to the hydraulic rod 227;

[0051] The detection mechanism 22 is installed one-to-one based on the clutch system of the car, so that the detection environment of the clutch 1 is more in line with reality, indirectly ensuring the accuracy of the detection results of the clutch 1. In addition, the laser pen 21 cooperates with the detection flywheel 221 for detection, and the straightness of light further ensures the detection accuracy of the fixed tooling 2.

[0052] Furthermore, Figure 5 As shown, the detection flywheel 221 in the detection mechanism 22 of the clutch dynamic balance detection fixing tool is embedded in the middle of the light ring 2212 and fixedly connected thereto, and the light ring 2212 is fixedly connected to the outer edge of the outer side of the flywheel body 2211, and the light absorption strip 2213 is opposite to the output end of the laser pen 21.

[0053] It should be noted that the present invention is a fixed fixture for detecting dynamic balance of a clutch. The detection flywheel 221 is provided. During the process of detecting the dynamic balance performance of the clutch 1, the detection flywheel 221 rotates based on the connecting shaft 222 through the corresponding support bearing 223.

[0054] During the rotation of the flywheel body 2211, the laser pen 21 is turned on, and the laser light emitted by the laser pen 21 is directed towards the light absorbing strip 2213 located in the middle of the light ring 2212, and the laser light is irradiated on the light absorbing strip 2213;

[0055] If the dynamic balance performance of the clutch 1 is poor, that is, the clutch 1 may vibrate during rotation, the laser light emitted by the laser pen 21 will deviate from the light absorbing strip 2213 to the light ring 2212. The light ring 2212 will reflect the laser light, making the laser light more conspicuous. In this way, the operator can know whether the clutch 1 has deviated during rotation.

[0056] Among them, the light absorbing strip 2213 is made of black material, and the light ring 2212 is made of white material. If the light absorbing strip 2213 is irradiated by laser, the black light reflected by the light absorbing strip 2213 is not easily perceived by the operator. When the laser is irradiated by the light ring 2212, the light ring 2212 can effectively reflect red light, thereby allowing the operator to more quickly perceive the dynamic balance performance defects of the clutch 1.

[0057] Those skilled in the art should know that, corresponding to the present technical solution, the transmission device and oil supply device proposed above are both common mechanical devices on the market. For example, the oil supply device can adopt a general high-pressure oil supply pump, which can be selected according to actual usage requirements.

[0058] The basic principles, main features and advantages of the present invention are shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
