Description

Technical Field

[0001] The invention relates to an online automatic detection machine for a transmission shaft movable end section, belonging to automatic detection equipment in the assembly of a vehicle transmission shaft movable end section. Background Art

[0002] The transmission shaft of the car constant velocity universal joint is composed of a moving end joint, an intermediate shaft and a fixed end joint. Among them, the moving end joint is an important safety component of the transmission shaft and is directly connected to the differential of the car engine. The power of the engine is transmitted to the wheel through the differential, the moving end joint, the intermediate shaft, the fixed end joint and the wheel hub, thereby driving the wheel to rotate. The moving end joint (workpiece) is composed of an outer sleeve, an inner sleeve, a retainer, a steel ball, and an accessory sleeve, a rubber cover, grease, and a clamp. The functional characteristics of the moving end joint, such as sliding force, sliding stroke, number of steel balls, and air tightness, have a vital impact on the assembly function of the transmission shaft. If the above functional characteristics are unqualified, the function of the assembly will be affected, and there will be problems such as abnormal noise, severe wear, reduced transmission efficiency, and shortened service life of the moving end joint. There will be shaking when the vehicle turns. What is more serious is that the retainer will break and the transmission shaft will fail, causing accidents, user dissatisfaction, and the risk of recall. In the past, the functional inspection of the moving end joint was carried out in the laboratory. It cannot be 100% tested online, and the inspection cost is high and the efficiency is low. Since 100% detection is not possible, it often happens that the function is unqualified when the assembly is re-checked. In this case, it is necessary to re-test the function of the batch of transmission shafts 100%, disassemble the mobile end section of the unqualified transmission shaft, and replace the unqualified parts to meet the requirements of the sliding force, sliding stroke, air tightness, etc. of the mobile end section. After disassembling the mobile end section, the clamp, steel ball, grease, sheath, rubber cover and other parts of the mobile end section are all scrapped, resulting in serious waste of materials and materials, increasing production costs, and leading to low assembly efficiency. If the transmission shaft equipped with unqualified mobile end sections is shipped to the user, grease leakage or abnormal noise will occur after the transmission shaft is used for a period of time, and even the phenomenon of being unable to assemble and stopping the line when loading on the main engine factory site will occur, resulting in user returns or claims, causing huge losses to the unit. Therefore, there is an urgent need for a machine that can automatically detect the function of the mobile end section and has reliable and efficient test results at the assembly site, so as to replace the laboratory sampling method, which not only improves production efficiency, but also 100% guarantees that the function of the mobile end section is qualified.

If the set force and displacement range or the set number of steel balls is exceeded, an alarm is sounded, indicating that the function test of the mobile end section is unqualified. The force value is transmitted to the controller through the pressure sensor, and the controller compares it with the set force to finally determine whether the function of the mobile end section to be tested is qualified.

Since 100% detection is not possible, it often happens that the function of the entire shaft after assembly is unqualified when it is re-inspected. In this case, it is necessary to re-test the 100% function of the batch of transmission shafts, disassemble the mobile end sections of the unqualified transmission shafts, and replace the unqualified parts to meet the requirements of the sliding force, sliding stroke, number of steel balls, air tightness, etc. of the mobile end section. After disassembling the mobile end section, the clamps, steel balls, grease, sheaths, rubber covers and other parts of the mobile end section are all scrapped, resulting in serious waste of materials and materials, increased production costs, and low assembly efficiency. If a transmission shaft with an unqualified mobile end section is shipped to the user, abnormal noise will occur after the transmission shaft is used for a period of time, and even the assembly line will be stopped when it is installed on the main engine factory site, resulting in user returns or claims, causing huge losses to the company. The present invention solves this problem and realizes online detection instead of laboratory sampling. It not only improves production efficiency, but also 100% guarantees that the function of the mobile end section is qualified, improves product quality, and improves its detection efficiency by at least 20 times (laboratory sampling takes 10 minutes, and online detection takes 27 seconds), increases customer satisfaction, and enhances the core competitiveness of the enterprise.

[0064] The symmetrical upper boss of the clamping jaw and the symmetrical lower boss of the clamping jaw are conical.

[0065] The frame is provided with a closed cover 81, which is composed of a frame and a translucent or opaque plate fixed in the frame. The mobile beat leveling mechanism 4, the sliding force detection mechanism 3, the steel ball quantity detection mechanism 25, the sheath flipping mechanism 23, the sheath pre-beating mechanism 17, the NG material channel 12, and the transplanting mechanism 7 are all placed in the closed cover. The closed cover is used to protect the various components, and the on-site operator can observe the operation status of the equipment in real time through the touch screen.

[0066] The working process and principle of the present invention are as follows: put the assembled mobile end section (measured workpiece) on the locator A of the first station of the turntable, make the end of the outer sleeve with the annular groove face upward, and make the locating pin A be located in the six-equally divided through hole of the mobile end section, put the large end of the sleeve face upward on the locator B, and make the locating pin B be located in the six-equally divided hole of the sleeve. When the start button is pressed, the sensor A detects that there is a mobile end section on the locator A, and the sensor B detects that there is a sleeve on the locator B, the O-ring presence and the front and back detection camera of the mobile end section start to detect the front and back of the mobile end section and whether there is an O-ring in the annular groove of the outer sleeve (some mobile end sections require an O-ring in the annular groove of the outer sleeve, and some end sections do not require an O-ring), and the sealing gasket detection switch starts to detect whether there is a sealing gasket on the mobile end section (some end sections require a sealing gasket, and some end sections require glue). The telescopic end of the lifting cylinder A in the mobile beat leveling mechanism (4) moves downward, thereby driving the slider A and the pressure head A on it to move downward along the double guide rail A. At this time, the lifting mechanism of the first station of the turntable starts to move: the telescopic end of the lifting cylinder under the first station of the turntable rises, pushing the lower plate to drive the sliding column to move upward along the sliding sleeve, driving the fixture seat A and the positioner A and the mobile end section on it to rise, and the upper end of the inner sleeve in the mobile end section contacts and presses the downward moving pressure head A, pressing the inner sleeve in the mobile end section to be corrected, preparing for subsequent work, and then the lifting cylinder A and the lifting cylinder each retreat to their original positions, and the pressure head A and the mobile end section each return to their original positions. The role of the lifting cylinder to lift the mobile end section is to prevent the pressure head from pressing down and deforming the turntable, and to protect the turntable. The motor drives the turntable to rotate through the transmission belt and the turntable divider. When the first induction switch on the right side of the induction switch group and the induction switch A light up in pairs, it means that the turntable has moved to the required working position.

[0067] The turntable divider rotates, driving the turntable to rotate 90 degrees clockwise. The middle induction switch and induction switch D in the induction switch group light up in pairs, indicating that the turntable is in place. When the opposing sensor A and the opposing sensor B sense that there is a moving end section and a sleeve at the second station of the turntable, in the gap detection mechanism, the telescopic end of the lifting cylinder B drives the slide plate B and the sliding force detection pressure ring on it to move downward along the vertical single guide rail and make the sliding force detection pressure ring press the end face of the outer ring of the moving end section. At the same time, the lifting mechanism starts to move, driving the moving end section to rise as in the first station of the turntable. The telescopic end of the sliding force detection electric cylinder drives the slide plate A, the force sensor, the connecting plate A, the double guide column, the clamping cylinder A and the symmetrical clamping claw A on it to move downward through the connecting piece, so that the symmetrical clamping claw A enters the inner hole of the inner ring of the moving end section. When the inner sleeve is within the range of the upper boss of the symmetrical clamping claw and the lower boss of the symmetrical clamping claw, the clamping cylinder A expands and clamps the inner sleeve of the moving end section between the upper and lower bosses of the symmetrical clamping claw to prevent it from moving. The symmetrical jaw A continues to move downward until it reaches the set position, the sliding force detection electric cylinder records the operating position, the force sensor measures the sliding force during operation, and displays the corresponding curve of sliding force and displacement on the touch screen; the symmetrical jaw A moves upward until it reaches the set position, the sliding force detection electric cylinder records the operating position again, the force sensor measures the sliding force during operation again and displays the corresponding curve of sliding force and displacement on the touch screen. The clamping cylinder A moves downward to the set position again and contracts, so that the symmetrical jaw A can be moved out of the sleeve hole in the moving end section. Within the set displacement range, if the sliding force is qualified, it means that the sliding force and sliding stroke of the moving end section are qualified, otherwise an alarm prompts. The telescopic end of the lifting cylinder B drives the slide plate B and the sliding force detection pressure ring on it to rise and retreat to the original position. The sliding force detection electric cylinder drives the symmetrical jaw A to rise and retreat to the original position.

[0068] The turntable divider rotates, driving the turntable to continue rotating 90 degrees clockwise. The middle induction switch and the right induction switch in the induction switch group light up in pairs with induction switch C, indicating that the turntable has rotated to the right position. When sensor C and sensor D sense that there are movable end sections and sheaths at the third station of the turntable, in the steel ball quantity detection mechanism, the steel ball quantity detection electric cylinder drives the slider B and the steel ball quantity detection camera on it to move downward along the double guide rail B to the top of the movable end section to detect the number of steel balls. After detection, the steel ball quantity detection electric cylinder drives the steel ball quantity detection camera back to its original position. If the number of steel balls does not match the set number, an alarm prompts. In the sheath flipping mechanism, the horizontal cylinder B drives the sheath flipping electric cylinder to move along the horizontal single guide rail to a position relative to the sheath, the telescopic end of the sheath flipping electric cylinder drives the rotating cylinder, the clamping cylinder B and the symmetrical clamping claw B to fall to the outside of the mobile end section, the symmetrical clamping claw B clamps the mobile end section, the telescopic end of the sheath flipping cylinder lifts the symmetrical clamping claw B to the specified position, the rotating cylinder drives the clamping claw B to flip the sheath 180 degrees so that the large end of the sheath faces downward, the horizontal cylinder B drives the sheath flipping electric cylinder to move along the horizontal single guide rail to a position relative to the mobile end section, the telescopic end of the sheath flipping electric cylinder drives the symmetrical clamping claw B to move downward and put the sheath on the mobile end section, the clamping cylinder B drives the symmetrical clamping claw B to release, the telescopic end of the sheath flipping cylinder drives the clamping claw B to rise to the specified position, the rotating cylinder rotates 180 degrees, and the horizontal cylinder B drives the sheath flipping cylinder back to its original position. In the sheath pre-shooting mechanism, the horizontal cylinder A drives the vertical cylinder A to move above the mobile end section, and the telescopic end of the vertical cylinder A drives the sheath pressing plate to move downward so that the large end of the sheath and the mobile end section fit together and are placed straight. At the same time, the lifting mechanism starts to move, driving the mobile end section to rise like the second station of the turntable. The telescopic end of the vertical cylinder A drives the sheath pressing plate to rise to the original position, and the horizontal cylinder A drives the vertical cylinder A back to the original position.

[0069] The turntable divider rotates, driving the turntable to continue rotating 90 degrees clockwise. The left induction switch and induction switch B in the induction switch group light up in pairs, indicating that the turntable has been rotated to the right position. When the through-beam sensor C and the through-beam sensor D detect that there is a moving end section on the turntable station 4 and there is no cover, in the transfer mechanism, the horizontal electric cylinder drives the horizontal slide and the vertical cylinder B, the clamping cylinder C, and the symmetrical clamping claw C on it to move to the top of the moving end section of the turntable station 4. The telescopic end of the vertical cylinder B drives the clamping cylinder C and the symmetrical clamping claw C to fall to the outside of the moving end section. The symmetrical clamping claw C clamps the moving end section. The telescopic end of the vertical cylinder B rises to the specified position. The horizontal electric cylinder drives the horizontal slide and the vertical electric cylinder B to transfer the moving end section to the next station together with the moving end section, and the transfer mechanism returns to its original position. This completes a cycle. When the moving end section and the cover are placed on the turntable station 1 and the start button is pressed again, the next cycle begins.

[0070] When the through-beam sensor D detects the presence of a sheath, it means that the sheath at the third station of the turntable is not correctly placed on the moving end section, and the equipment alarm prompts.

[0071] Regardless of which turntable station, the equipment will give an alarm prompt, but will not stop. The equipment will record the unqualified mobile end section prompted by the alarm prompt, and when the turntable is at the fourth station, the unqualified mobile end section will be placed on the NG material channel by the transplanting mechanism. When the through-shooting sensor E detects that there is a mobile end section on the NG material channel, the telescopic end of the push cylinder extends to push the mobile end section out, and the mobile end section moves downward on the gravity slide, and the push cylinder returns to its original position. When the through-shooting sensor F detects that there is a mobile end section, it means that the NG material channel is full, and the operator is prompted to clear the unqualified mobile end sections on the NG material channel in time.

[0072] like Fig.33 As shown, the mobile end section (the workpiece to be inspected) is composed of an outer sleeve 106, an inner sleeve 109, a retainer 108, and a steel ball 107; the outer sleeve of the mobile end section is provided with an annular groove 112, six equally divided through holes 114, and an inner equally divided oblique ball track 113; the inner sleeve of the mobile end section is provided with an inner sleeve inner hole 110, and an outer equally divided oblique ball track 111; the retainer is provided with an equally divided window 105. The inner equally divided oblique ball track of the outer sleeve of the mobile end section corresponds to the outer equally divided oblique ball track of the inner sleeve of the mobile end section and the equally divided windows of the retainer, and the steel balls are located in the corresponding ball tracks and windows. The inner sleeve, retainer, and steel ball assembly of the mobile end section can move forward and backward axially and swing in the outer sleeve of the mobile end section. The equally divided ball tracks are usually divided into six equal parts, and the ones used in high-end cars are divided into eight equal parts.

[0073] like Fig.35 , 36 As shown, the sleeve 86 has a large sleeve end 115, which is provided with six equally divided holes 117, and is coated with sealant 116 before assembly (when assembling a product requiring a sealing gasket on the end face of the movable end section sleeve, sealant does not need to be applied to the sleeve).

[0074] The servo motor is a prior art product, and the servo motor can accurately control the rotation angle.

[0075] The servo electric cylinder is a prior art product, and the servo electric cylinder can accurately control the displacement.

[0076] The telescopic cylinder described in this article is a mechanical product of the prior art. The telescopic cylinder generally has a cylinder body as a fixed end, and the cylinder body is fixedly mounted on a component corresponding thereto. The telescopic cylinder also has a telescopic end as a moving end, and the telescopic end is also called a telescopic rod. The telescopic end reciprocates along its axial direction within a designed stroke. The telescopic cylinder is mainly divided into pneumatic telescopic cylinders, electric telescopic cylinders, electromagnetic telescopic cylinders and hydraulic telescopic cylinders, etc. In the present application, pneumatic telescopic cylinders and electric telescopic cylinders are preferred; among them, the pneumatic telescopic cylinder is a prior art product that converts pressurized gas into mechanical action. The pressurized gas output from the total on-site gas source is filtered and stabilized through the gas source triplet and then transported to each pneumatic telescopic cylinder through each gas pipe for use.

[0077] The controller and each actuator and each electronic device that needs to be shielded and protected are installed in an electrical cabinet 61 arranged on site. The human-machine interface of the controller is preferably a touch screen. The touch control display end of the touch screen is arranged on the surface of the electrical cabinet or installed on the rack, which is convenient for on-site staff to operate.

[0078] The turntable divider is a prior art. The working principle of the turntable divider is that the conjugate cam on the input shaft and the indexing disk with uniformly distributed needle bearings on the output shaft are meshed vertically without gap. The curve segment of the cam profile surface drives the needle bearings on the indexing disk to drive the indexing disk to rotate, and the straight segment makes the indexing disk stationary and self-locked. Under normal circumstances, the input shaft rotates one circle (360°), and the output shaft completes a division process of one movement and one stop. In a division process, the angle occupied by the straight segment on the cam circumference is called the static angle, and the sum of the dynamic angle and the static angle is 360°. The number of workstations of the turntable divider (that is, 360° divided by the angle Ф of each output shaft transfer is the number of workstations N, N = 360° ÷ Ф). The number of workstations of the present invention is 4, and the turntable rotates 90° each time, and the number of workstations N = 360 ÷ 90 = 4. The number of workstations is related to the number of needle bearings loaded on the output shaft indexing disk. Under normal circumstances, the number of needle bearings on the indexing disk is the same as the number of workstations.
