Description

Technical Field

[0001] The present invention relates to the technical field of transmission shaft detection, and in particular to a verticality detection device and method based on automobile transmission shaft processing. Background Art

[0002] The automobile drive shaft is an important component of the automobile power transmission system. It is mainly used to connect the engine and the drive wheels to transmit the power generated by the engine to the wheels. The design of the drive shaft needs to take into account factors such as the type of vehicle, drive mode (front drive, rear drive or four-wheel drive) and specific application scenarios. The drive shaft is usually made of steel pipe. In order to reduce weight and increase strength, aluminum alloy or other lightweight and high-strength materials are sometimes used. In order to prevent the automobile drive shaft from vibrating during use and improve its operating stability, the automobile drive shaft is usually tested for verticality before installation and use.

[0003] Publication number CN107036558B discloses a device for detecting the spatial verticality of the axis of the drive shaft seat hole of a worm gear reducer. The above application includes a three-claw positioning mechanism in the input axis, a three-claw positioning mechanism in the output axis, a laser receiver (CCD sensor, lens), an input axis axis determining member, an output axis axis determining member, a laser, a multi-degree-of-freedom fine-tuning mechanism, a beam splitter prism (beam splitter prism cover, beam splitter prism base), a 180° beam splitter prism (180° beam splitter prism cover, 180° beam splitter prism base), a cross-hair plate, and an adjustment device.

[0004] Although the structures used in the above-mentioned applications and the prior art are relatively simple and cause no damage or little damage to the test object, when the above-mentioned applications and the prior art perform verticality detection on the automobile drive shaft, most of them can only perform verticality detection on a certain surface of the automobile drive shaft, and cannot perform verticality detection on other surfaces of the automobile drive shaft. Therefore, the results of the verticality detection are prone to errors, which in turn affects the subsequent normal use of the automobile drive shaft. When detecting other surfaces of the automobile drive shaft, the surface of the automobile drive shaft will rub against the detection support platform, which will cause damage to the surface of the automobile drive shaft, which will affect the subsequent normal use. When detecting other surfaces of the automobile drive shaft, due to the different sizes of the automobile drive shaft, the automobile drive shaft will tilt inside the detection support platform when rotating, which will affect the subsequent verticality detection results. Therefore, we propose a verticality detection device and detection method based on automobile drive shaft processing. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides a verticality detection device and method based on automobile drive shaft processing, which has the advantages of multi-directional detection, friction prevention and tilt prevention, etc., and solves the problem that when the above-mentioned applications and the prior art perform verticality detection on the automobile drive shaft, most of them can only perform verticality detection on a certain surface of the automobile drive shaft, but cannot perform verticality detection on other surfaces of the automobile drive shaft. Therefore, the result of the verticality detection is prone to errors, which in turn affects the subsequent normal use of the automobile drive shaft. When detecting other surfaces of the automobile drive shaft, the surface of the automobile drive shaft will rub against the detection support platform, which will cause damage to the surface of the automobile drive shaft, thereby affecting the subsequent normal use. When detecting other surfaces of the automobile drive shaft, due to the different lengths of the automobile drive shaft, the automobile drive shaft will tilt inside the detection support platform when rotating, thereby affecting the subsequent verticality detection results.

The lifting assembly includes a lifting plate slidably connected to the interior of the inspection platform, the bottom of the lifting plate is fixedly connected to a first mounting platform, the interior of the first mounting platform is rotatably connected to a rolling wheel, and the top of the lifting plate is fixedly connected to a plurality of second mounting platforms, and the interiors of the plurality of second mounting platforms are all rotatably connected to anti-scratch wheels; The anti-tilt component is arranged on the surface of the lifting component and is used to prevent the transmission shaft from tilting when the rotating component rotates the transmission shaft.

[0007] Furthermore, the lifting assembly also includes a driving motor fixedly connected to the inside of the detection box, the output end of the driving motor is fixedly connected to a bidirectional screw, the surface of the bidirectional screw is threadedly connected to a first T-shaped screw plate, and one side of the first T-shaped screw plate is fixedly connected to a tilting platform.

[0008] Furthermore, a rolling groove for the rolling wheel to move is provided on the top of the tilting platform, and an insertion groove for the tilting platform to move is provided on the surface of the detection platform.

[0009] Furthermore, the rotating assembly includes a support bar fixedly connected to the surface and back of the first T-shaped screw plate and a rotating rod fixedly connected to the inside of the anti-scratch wheel, and the surface of the support bar is fixedly connected to the T-shaped tooth plate.

[0010] Furthermore, the rotating rod is rotatably connected to the plurality of second mounting platforms, a fixed gear is fixedly connected to the surface of the rotating rod, and the fixed gear is meshed with a T-shaped gear plate for transmission.

[0011] Furthermore, the anti-skew assembly includes a second T-shaped screw plate threadedly connected to the surface of the bidirectional screw, and three fixed cylinders are fixedly connected to one side of the second T-shaped screw plate. The interiors of the three fixed cylinders are all fixedly connected to extrusion springs, and the interiors of the fixed cylinders are all slidably connected to extension cylinders.

[0012] Furthermore, one end of the extrusion spring is fixedly connected to one end of the extension tube, and the end of the extension tube away from the extrusion spring is internally rotatably connected to a limiting wheel, and a rubber layer is provided on the surface of the limiting wheel.

[0013] Furthermore, a number of fixed blocks are fixedly connected to the inner wall of the arc groove inside the detection platform, and auxiliary wheels are rotatably connected to the interior of the several fixed blocks. Three slots are opened on one side of the detection platform for the movement of the fixed cylinder and the extension cylinder.

[0014] Furthermore, a control panel is provided on the surface of the detection box, an audible and visual alarm is fixedly connected to the top of the detection box, a movable groove for the movement of the T-shaped gear plate is provided inside the detection box, a box door is hinged on the surface of the detection box, and an observation window is provided on the surface of the box door.

[0015] The present invention also provides a verticality detection method based on automobile transmission shaft processing, and the verticality detection method specifically comprises the following steps: Step 1: Place the automobile transmission shaft to be tested in the arc trough, and then use the detection component to test the verticality of the automobile transmission shaft; Step 2: When it is necessary to detect the verticality of different surfaces of the automobile drive shaft, the drive motor is started, and the drive motor drives the first T-shaped screw plate to move through the bidirectional screw, so that the first T-shaped screw plate drives the T-shaped tooth plate to move through the support bar. As the T-shaped tooth plate continues to move, the T-shaped tooth plate engages with the fixed gear, and then drives the rotating rod to rotate through the fixed gear. The rotating rod drives the automobile drive shaft to rotate through the anti-scratch wheel, so that different surfaces of the automobile drive shaft gradually face the detection component, so that the detection component can detect different surfaces of the automobile drive shaft; Step 3: When it is necessary to avoid friction between the automobile transmission shaft and the inspection platform during rotation, the bidirectional screw drives the first T-shaped screw plate to drive the tilting platform to be inserted into the insertion groove. As the tilting platform is continuously inserted, the rolling wheel rolls in the rolling groove, and then the rolling wheel drives the lifting plate to rise through the first mounting platform. The second mounting platform lifts the automobile transmission shaft through the anti-scratch wheel, so that the other surface of the automobile transmission shaft contacts the auxiliary wheel. Then, when the automobile transmission shaft rotates, the surface of the automobile transmission shaft does not contact the inspection platform, thereby avoiding friction between the automobile transmission shaft and the inspection platform. Step 4. When it is necessary to prevent the automobile drive shaft from deflecting during rotation, while the bidirectional screw drives the first T-shaped screw plate to move, the bidirectional screw drives the second T-shaped screw plate to move, so that the second T-shaped screw plate drives the fixed cylinder and the extension cylinder to be inserted into the slot. As the fixed cylinder and the extension cylinder continue to move, the limiting wheel gradually contacts the surface of the automobile drive shaft, so that the automobile drive shaft squeezes the extension cylinder through the limiting wheel, and then the extension cylinder is accommodated in the fixed cylinder and compresses the extrusion spring. Through the expansion and contraction tension of the extrusion spring, the limiting wheel is always in contact with the surface of the automobile drive shaft, so as to prevent the automobile drive shaft from tilting during rotation, thereby affecting the subsequent verticality detection.

[0016] Compared with the prior art, the present invention provides a verticality detection device and method based on automobile transmission shaft processing, which has the following beneficial effects: 1. The verticality detection device and detection method based on automobile drive shaft processing, through the coordinated use of the detection platform and the lifting component, start the drive motor, and the drive motor drives the first T-shaped screw plate to drive the tilting platform to be inserted into the insertion groove through the bidirectional screw. As the tilting platform is continuously inserted, the rolling wheel rolls in the rolling groove, and then the rolling wheel drives the lifting plate to rise through the first mounting platform. The second mounting platform lifts the automobile drive shaft through the anti-scratch wheel, so that the other surfaces of the automobile drive shaft contact with the auxiliary wheel. Then, when the automobile drive shaft is rotating, the surface of the automobile drive shaft will not contact the detection platform, thereby avoiding friction between the automobile drive shaft and the detection platform, thereby achieving the effect of preventing friction.

[0017] 2. This verticality detection device and detection method based on automobile drive shaft processing uses a lifting component and a rotating component in conjunction with each other. When the first T-shaped screw plate moves, the first T-shaped screw plate drives the T-shaped tooth plate to move through the support bar. As the T-shaped tooth plate continues to move, the T-shaped tooth plate engages with the fixed gear, and then drives the rotating rod to rotate through the fixed gear. The rotating rod drives the automobile drive shaft to rotate through the anti-scratch wheel, so that different surfaces of the automobile drive shaft gradually face the detection component, and then the detection component can detect different surfaces of the automobile drive shaft, thereby achieving the effect of multi-directional detection.

[0018] 3. The verticality detection device and detection method based on automobile drive shaft processing, through the coordinated use of a lifting component and an anti-tilt component, while the bidirectional screw drives the first T-shaped screw plate to move, the bidirectional screw drives the second T-shaped screw plate to move, so that the second T-shaped screw plate drives the fixed cylinder and the extension cylinder to be inserted into the slot; as the fixed cylinder and the extension cylinder continue to move, the limiting wheel gradually contacts the surface of the automobile drive shaft, so that the drive shaft squeezes the extension cylinder through the limiting wheel, and then the extension cylinder is accommodated in the fixed cylinder and compresses the extrusion spring; through the expansion and contraction tension of the extrusion spring, the limiting wheel is always in contact with the surface of the automobile drive shaft, avoiding the automobile drive shaft from tilting when rotating, thereby affecting the subsequent verticality detection, thereby achieving the effect of preventing tilting.

The rotating rod 32 drives the automobile drive shaft to rotate through the anti-scratch wheel 234, so that different surfaces of the automobile drive shaft gradually face the detection component 13, so that the detection component 13 can detect different surfaces of the automobile drive shaft; Step 3: When it is necessary to prevent the automobile transmission shaft from rubbing against the inspection platform 14 during rotation, the bidirectional screw 211 drives the first T-shaped screw plate 212 to drive the tilting platform 22 to be inserted into the insertion groove 143. As the tilting platform 22 is continuously inserted, the rolling wheel 232 rolls in the rolling groove 221, and then the rolling wheel 232 drives the lifting plate 23 to rise through the first mounting platform 231. The second mounting platform 233 lifts the automobile transmission shaft through the anti-scratch wheel 234, so that the other surface of the automobile transmission shaft contacts the auxiliary wheel 142.

When it is necessary to prevent the automobile transmission shaft from tilting during the rotation process, the bidirectional screw 211 drives the first T-shaped screw plate 212 to move, and the bidirectional screw 211 drives the second T-shaped screw plate 41 to move , so that the second T-shaped screw plate 41 drives the fixed cylinder 411 and the extension cylinder 42 to be inserted into the slot 145. As the fixed cylinder 411 and the extension cylinder 42 continue to move, the limiting wheel 421 gradually contacts the surface of the automobile drive shaft, so that the automobile drive shaft squeezes the extension cylinder 42 through the limiting wheel 421, and then the extension cylinder 42 is accommodated in the fixed cylinder 411 and compresses the extrusion spring 412.
