Description

Technical Field

[0001] The invention relates to the field of flywheel accessories production, and in particular to a quality inspection device for flywheel gear ring processing and production. Background Art

[0002] The flywheel ring gear is a gear ring installed on the outside of the flywheel. Since the flywheel is a component that transmits the power between the engine and the clutch, there are certain requirements for the stability of the flywheel during operation. During the manufacturing process of the flywheel ring gear, some processing errors may cause deviations in the size of the inner ring of the ring gear, so the radial runout of the inner ring must be tested. Most existing tests use a positioning device to rotate the ring gear, and then use a dial indicator to test the inner ring. During the testing process, workers need to observe the value of the dial indicator and then distinguish unqualified ring gears. Manual observation of the dial indicator value throughout the process results in a high error rate and high labor intensity.

[0003] If high-end testing equipment is used and judged through programs, the accuracy can be maximized. However, the use and maintenance costs of electronic equipment are relatively high, and during the testing process, only the results are needed, and it is not necessary to understand all the specific data. Therefore, this type of professional testing equipment is generally only suitable for use in the research and development process and is not suitable for factory production.

[0004] In addition, most of the existing rotating gear ring devices can only position and rotate gear rings of one size, and gear rings of different sizes need to be re-adjusted before they can be put into use, and the adaptability is poor. Summary of the invention

[0005] The object of the present invention is to provide a quality inspection device for flywheel ring gear processing and production to solve the problems mentioned in the above background technology.

[0007] The detection component determines whether the size of the inner ring of the gear ring is qualified by the displacement change amount generated after the contact rod contacts the inner ring of the gear ring.

The travel switch is arranged between the drive frame and the trigger block and is fixedly connected to the drive frame, and when the travel switch is triggered, the output shaft of the hydraulic cylinder stops extending and self-locks.

[0010] Preferably, the detection component includes a linear module and a base plate, the base plate is fixedly connected to the slide table of the linear module, the linear module is fixedly connected to the workbench, the base plate is fixedly connected with a guide block, a limit plate 1 and a limit plate 2 in sequence from the outside to the inside, the contact rod passes through the guide block and the limit plate 1, and is slidably connected to both, the contact rod is provided with a baffle, the baffle is located between the limit plate 1 and the guide block, the contact rod between the baffle and the limit plate 1 is sleeved with a spring 1, the front end of the contact rod is provided with a ball bearing, and the rear end of the contact rod is fixedly connected with a trigger plate, the trigger plate is provided with a power connection column, the limit plate 1 is provided with a contact 1, and the limit plate 2 is provided with a contact 2.

[0011] Preferably, an indicator light is provided on the workbench. When the contact one is disconnected from the power post two for the first time, the indicator light goes out. At this time, an electrical signal is sent to the controller to control the linear module to stop running and start the rotating motor. When the contact two is connected to the power post and the contact one is connected to the power post, the indicator light will light up, and the gear ring is unqualified.

[0012] Preferably, the axis of the contact rod points to the midpoint of the line connecting the centers of the two positioning friction wheels, and the workbench is provided with slots for the detection assembly and the positioning friction wheels to move.

[0013] The advantages of the present invention are:

[0014] The two positioning friction wheels are driven by the same driving device, and the booster assembly is used to detect in real time whether the contact pressure between the positioning friction wheel and the gear ring reaches the preset value, so as to automatically control the driving device to close. When replacing different gear rings, the position of the positioning friction wheel can be automatically adjusted, which has strong adaptability and eliminates the trouble of manual debugging.

[0016] When the connecting post is between contact two and contact one, the gear ring is qualified. Once the connecting post is connected to any contact, it means that the distance from that point on the inner circle to the center of the gear ring does not meet the tolerance value, and the indicator light will be triggered to light up, thereby judging that the gear ring is unqualified.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] like Figures 1 to 4As shown, a quality inspection device for flywheel gear ring processing and production includes a workbench 1, a contact rod 3 and a detection component 4. The bottom of the workbench 1 is slidably connected to two slides 5 through a guide rail. Two positioning friction wheels 6 are rotatably connected to the slides 5. One of the positioning friction wheels 6 is also fixedly connected to the output shaft of the rotating motor 7. The positioning friction wheel 6 is located above the workbench 1. The positioning friction wheel 6 is made of rubber to increase the friction with the gear ring. The two slides 5 are each connected to the driving device 9 through a pressurizing component 8 to achieve synchronous approach and separation.

[0028] In this embodiment, the driving device 9 includes a hydraulic cylinder 91, the output shaft of the hydraulic cylinder 91 is fixedly connected to a hinge block 92, the hinge block 92 is slidably connected to the workbench 1, two push rods 93 are symmetrically hinged on the hinge block 92, and the other end of each push rod 93 is hinged to a C-shaped driving frame 94; the front end of the driving frame 94 is fixedly connected to a support block 95, and the slide plate 5 and the support block 95 are connected via a pressurizing component 8.

[0029] In this embodiment, the pressurizing assembly 8 is used to detect the contact pressure between the positioning friction wheel 6 and the inner wall of the gear ring, and automatically close the driving device 9 according to the pressure, and specifically includes a trigger block 80, a connecting block 81 and a travel switch 82. The trigger block 80 is arranged between the support block 95 and the travel switch 82. The connecting block 81 is fixedly connected to the slider and is located at the front side of the support block 95. Two guide rods 83 are fixedly connected between the trigger block 80 and the connecting block 81. The guide rods 83 are slidably connected to the support block 95. A spring 2 84 is arranged on the guide rods 83 between the connecting block 81 and the support block 95. The travel switch 82 is arranged between the driving frame 94 and the trigger block 80, and is fixedly connected to the driving frame 94. When the travel switch 82 is triggered, the output shaft of the hydraulic cylinder 91 stops extending and self-locks.

[0030] In this embodiment, the detection component 4 determines whether the inner ring size of the gear ring is qualified by the displacement change amount generated after the contact rod 3 contacts the inner ring of the gear ring, and specifically includes a linear module 40 and a base plate 41. The base plate 41 is fixedly connected to the slide of the linear module 40, and the linear module 40 is fixedly connected to the workbench 1. The base plate 41 is fixedly connected with a guide block 42, a limit plate 1 43 and a limit plate 2 44 from the outside to the inside. The contact rod 3 passes through the guide block 42 and the limit block The contact rod 3 is provided with a baffle 30, which is located between the limit plate 1 43 and the guide block 42. The contact rod 3 between the baffle 30 and the limit plate 1 43 is provided with a spring 1 45, which is used to reset the contact rod 3. The front end of the contact rod 3 is provided with a ball, and the rear end is fixedly connected with a trigger plate 46, which is provided with a power connection column 47. The limit plate 1 43 is provided with a contact point 1 48, and the limit plate 2 44 is provided with a contact point 2 49. The guide block 42, the limit plate 1 43, the limit plate 2 44 and the trigger plate 46 are all made of non-conductive material.

[0031] In this embodiment, an indicator light 2 is provided on the workbench 1, and contact 1 48 and contact 2 49 are both connected to the negative pole of the indicator light 2, and the power pole 47 is connected to the power supply and then to the positive pole of the indicator light 2. When contact 1 48 and power pole 47 are disconnected for the first time, the indicator light 2 goes out, and an electrical signal is sent to the controller at this time, thereby controlling the linear module 40 to stop running and starting the rotating motor 7. When contact 2 49 is connected to power pole 47 and contact 1 48 is connected to power pole 47, the indicator light 2 will light up, and the gear ring is unqualified.

[0032] In this embodiment, the axis of the contact rod 3 points to the midpoint of the line connecting the centers of the two positioning friction wheels 6, thereby ensuring that the contact rod 3 points to the center of the positioned gear ring, and the workbench 1 is provided with a slot for the detection component 4 and the positioning friction wheel 6 to move.

[0033] Working process and principle:

[0034] When detection is required, the two positioning friction wheels 6 are in a close position, and the contact rod 3 is also located close to the center of the workbench 1 at this time.

[0035] Place the gear ring on the workbench 1 and put it on the outer side of the positioning friction wheel 6 and the contact rod 3. Start the hydraulic cylinder 91, the output shaft of the hydraulic cylinder 91 extends, and pushes the hinge block 92 to slide toward the center of the workbench 1. The two push rods 93 hinged to the hinge block 92 are opened at an angle relative to each other to push the two drive frames 94 to move outward, and the support block 95 on the front side of the drive frame 94 applies a force to the spring 2 84. When the positioning friction wheel 6 has not yet contacted the gear ring, the slider is not affected by other external forces, so it can be pushed to move to both sides by the spring 2 84.

[0036] When the positioning friction wheels 6 just start to contact the ring gear, the two positioning friction wheels 6 can push the ring gear to automatically center to the center of the workbench 1. As the output shaft of the hydraulic cylinder 91 continues to extend, the two positioning friction wheels 6 are already in contact with the ring gear, so the positioning friction wheels 6 cannot continue to move, that is, the slide plate 5 remains stationary, the support plate continuously compresses the spring 2 84, the contact pressure between the positioning friction wheel 6 and the ring gear continues to increase, and the trigger plate 46 also continues to approach the travel switch 82 until the trigger plate 46 contacts the travel switch 82, triggering the travel switch 82. The controller receives this trigger signal and determines that the positioning friction wheel 6 has completely achieved the positioning work of the ring gear, and then closes the hydraulic cylinder 91 and allows the hydraulic cylinder 91 to maintain the extended length of the output shaft.

[0037] At the same time, the linear module 40 starts, driving the contact rod 3 to move outward. When the ball on the contact rod 3 contacts the gear ring, the gear ring causes the contact rod 3 to retract a certain distance inward, the power connection column 47 is disconnected from the contact point 1 48, and the signal indicator light 2 goes out. At this time, the controller detects this signal and controls the linear module 40 to close and the rotary motor 7 to start.

[0038] The rotating motor 7 drives one of the positioning friction wheels 6 to rotate, thereby utilizing the friction force between the positioning friction wheel 6 and the inner wall of the gear ring to drive the gear ring to start rotating. The inner wall of the gear ring remains in contact with the ball on the contact rod 3. The positioning friction wheel 6 rotates for a certain period of time, so that the number of revolutions of the gear ring is greater than or equal to one revolution.

[0039] Spring 1 45 acts on baffle 30, causing connection post 47 to move back and forth between contact 1 48 and contact 2 49. If the inner diameter of the gear ring is too small, contact rod 3 moves further inward, connection post 47 contacts contact 2 49, indicator light 2 lights up, and the gear ring is unqualified. On the contrary, connection post 47 contacts contact 1 48, indicator light 2 still lights up, and the gear ring is still unqualified. Only when connection post 47 moves between the two but never contacts contact 1 48 and contact 2 49, that is, indicator light 2 never lights up, the gear ring is qualified.

[0040] After that, the hydraulic cylinder 91 is started, the output shaft retracts, and the push rod 93 pulls the two positioning friction wheels 6 to move closer to each other and reset. The linear module 40 also drives the bottom plate 41 to move, so that the contact rod 3 is reset, and a detection is completed.

[0041] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
