Description

Technical Field

[0001] The invention relates to automatic assembly and detection equipment for a circlip, in particular to an online automatic assembly and detection machine for a circlip of a movable end shank of a car transmission shaft. Background Art

[0002] The constant velocity universal joint drive shaft of a passenger car consists of a fixed end joint, an intermediate shaft, and a movable end joint. The fixed end joint consists of an outer ring, an inner ring, a retainer, steel balls, a rubber cover, grease, and a clamp; the movable end joint consists of an outer sleeve, an inner sleeve, a retainer, steel balls, a sheath, a rubber cover, grease, and a clamp. The intermediate shaft is connected to the internal splines of the inner ring of the fixed end joint and the internal splines of the inner sleeve of the movable end joint via external splines at both ends. The intermediate shaft is axially locked in the retaining spring grooves on the inner and outer splines, thus connecting the intermediate shaft to the fixed and movable end joints. The fixed end joint is connected to the wheel hub via the external splines and threads of the shank, while the movable end joint is connected to the engine differential via the external splines of the shank and the retaining spring in the retaining spring groove on it. The connection between the moving end joint and the differential is crucial to the function of the driveshaft assembly. If the connection is unreliable, the moving end joint will fall off, causing the main engine manufacturer's assembly line to malfunction and production to stop, leading to customer dissatisfaction and recalls, resulting in significant losses for the company. If a driveshaft is shipped to the user with a missing retainer on the moving end joint shank, serious consequences such as vehicle and personnel damage, vehicle recalls, and heavy losses for the company can occur. Traditionally, the retainer assembly of the moving end joint shank of the driveshaft was performed by manually pressing the retainer into the retainer groove and visually inspecting its position. This labor-intensive process can lead to swollen fingers, and due to operator fatigue or lack of concentration, retainers can be missing or incorrectly positioned. If the retainer on the moving end joint shank is missing or incorrectly assembled during the complete shaft assembly, the entire batch of driveshaft assemblies must be unpacked and 100% inspected before being repacked. This not only reduces assembly efficiency but also increases costs. If a driveshaft assembly is shipped to the OEM with missing or incorrectly assembled parts, it could fall off and cause production to stop. Furthermore, if a driveshaft with a missing retainer on the shank is shipped to the customer, serious damage to the vehicle or personnel could occur, leading to recalls, returns, and claims from the OEM, resulting in significant losses for the manufacturer. Therefore, a highly efficient and reliable device is urgently needed on the production site to ensure automated assembly and testing of retainers on the shank. Summary of the Invention

Then, the slide plate B is equipped with a retaining spring feeding column, a retaining spring supporting plate, a retaining spring push plate, a retaining spring detection plate, a positioner, a guide mechanism, a limit mechanism, a power and transmission mechanism, a sensor, and a control mechanism. The positioner corresponds to the elastic top above it. The retaining spring feeding column is provided with a stop pin and a weight block. The lower end face of the retaining spring feeding column is opposite to the retaining spring supporting plate. There is a gap between the lower end face of the retaining spring feeding column and the retaining spring supporting plate. The height of the gap is set to the height of the diameter of the retaining spring wire. The retaining spring supporting plate is located below the retaining spring push plate, and the retaining spring push plate and the retaining spring supporting plate are slidably connected.

[0005] The guide mechanism includes: single guide rail A, single guide rail B, the limiting mechanism includes limiter A, limiter B, limiter C, limiter D, limiter E, the power and transmission mechanism includes: cylinder B, cylinder C, cylinder D, cylinder E, cylinder F, slider A, slider B, slider C, connecting plate, clamping block, wherein the telescopic end of cylinder B is fixedly connected to slider B, slider B is slidably connected to the single guide rail B, the retaining spring push plate is installed on slider B, slider A is slidably connected to the single guide rail B, the retaining spring support The material plate is mounted on slider A, and slider A is elastically connected to slider B through a spring; the telescopic ends of cylinder C and cylinder D are fixedly connected to the connecting plate, the connecting plate is fixedly connected to slider C, and slider C is slidingly connected to the single guide rail A. A retaining spring detection plate is fixedly mounted on the connecting plate, and the front end of the retaining spring detection plate is provided with a conformal groove B on the outside of the retaining spring opening side. The telescopic ends of cylinder E and cylinder F are fixedly connected to the clamping block, and the inner edge of the clamping block is opposite to the locator and the workpiece. The limiters A, B, C, D, E and sensors are fixedly mounted on slide B.

[0006] The control mechanism includes: a controller and an audible and visual alarm electrically connected to the controller, a touch screen, a start button, an emergency stop switch, a limit mechanism, and a sensor, wherein the audible and visual alarm and the touch screen are fixedly mounted on the frame, the start button and the emergency stop switch are mounted on the touch screen, and the controller is mounted in the electrical cabinet.

[0007] The frame is fixedly equipped with a handwheel A and a handwheel B. The handwheel A is connected to the screw A. The nut A is fixedly mounted on the back of the skateboard A. The screw A is rotatably connected to the nut A. The handwheel B is connected to the screw B. The nut B is fixedly mounted on the back of the skateboard B. The screw B is rotatably connected to the nut B. A slot is opened on the back of the frame. The two nuts behind the skateboards A and B are placed in the slot and are slidably connected to the slot.

[0008] The front end of the clamping spring push plate is provided with a conformal groove A on the outside of the non-opening side of the clamping spring.

[0009] The clip loading column is fixedly connected to the slide plate B via a quick-change screw.

[0010] The advantages of the present invention are: by using the retaining spring loading column and the weight block, the retaining spring can be automatically placed on the retaining spring supporting plate, and the retaining spring can be automatically driven into the retaining spring groove of the movable end section handle through the cylinder and the retaining spring pushing plate, and then the retaining spring detection plate automatically detects whether the retaining spring is in the retaining spring groove. Not only can the retaining spring be automatically assembled, but also the assembly quality of the retaining spring can be 100% guaranteed, thereby realizing online automatic assembly detection. In the past, the operator was required to press the retaining spring into the retaining spring groove by hand and visually check whether the retaining spring is in the retaining spring groove. The labor intensity of the operator was large and the fingers were swollen. In addition, due to the human factors of operator fatigue or lack of concentration, the retaining spring may be missed or the retaining spring may be incorrectly positioned. If the retaining spring of the movable end section handle is missed or the assembly position is incorrect when the whole shaft is assembled, the entire batch of transmission shaft assemblies needs to be unpacked and 100% inspected, and then repacked, which not only leads to low assembly efficiency but also increases costs. If a drive shaft assembly is shipped to the OEM with missing or incorrectly assembled parts, the moving end of the drive shaft may fall off and the production line may stop. Furthermore, if a drive shaft with a missing retaining ring on the shank of the moving end is shipped to the user, serious consequences such as vehicle and personnel damage may occur, leading to recalls, returns, and claims from the OEM, resulting in significant losses for the manufacturer. The present invention achieves automated assembly testing, replacing manual assembly testing. This frees up labor, reduces operator labor intensity, ensures 100% qualified products, avoids the waste of unpacking unqualified workpieces after assembly, improves production efficiency, increases customer satisfaction, and enhances the core competitiveness of the enterprise.

[0029] The front end of the retaining spring push plate is provided with a conformal groove A56 corresponding to the outside of the non-opening side of the retaining spring.

[0030] The retaining spring loading column 12 is fixedly connected to the slide plate B21 via a quick-change screw 50 .

[0031] The assembly detection principle of the present invention is: the movable end section is clamped by the clamping block, and the center hole of the handle is positioned and pressed by the pressure head and the elastic top thereunder, the stop pin at the lower end of the retaining spring upper column is pulled out, and the retaining spring falls onto the retaining spring supporting plate under the action of the gravity of the weight block, and a gap that just passes through the retaining spring is provided between the lower end surface of the retaining spring upper column and the retaining spring supporting plate, under the action of the cylinder B, the conformal groove A at the front end of the retaining spring push plate carries the retaining spring along the retaining spring supporting plate through the lower end of the retaining spring upper column toward the movable end section, and synchronously the retaining spring supporting plate moves toward the movable end section under the action of the spring and first contacts the handle of the movable end section. Under the action of the telescopic end of cylinder B, the circlip is quickly pushed into the circlip groove, and the telescopic end of cylinder B touches the limiter D, indicating that the cylinder has run into place; the circlip detection plate moves toward the moving end under the action of cylinders C and D, and the conformal groove B at the front end of the circlip detection plate contacts the circlip, and the telescopic ends of cylinders C and D do not contact the limiter A, indicating that there is a circlip in the circlip groove. If there is no circlip in the circlip groove, the telescopic ends of cylinders C and D will continue to move forward a distance of the diameter of the circlip wire and contact the limiter A. At this time, the sound and light alarm sends a signal to indicate that there is a problem with the circlip assembly and needs to be processed.

[0032] The working process of the present invention is as follows: first, the circlip loading column 12 is removed from the slide B21 by the quick-change screw 50, the circlip loading column is filled with circlips 10, and the latch is inserted. Then, the circlip loading column is installed by the quick-change screw, and the latch is pulled out. Then, under the action of the weight block 11, the circlip moves downward and falls onto the circlip supporting plate 5. The movable end section 30 is placed in the positioner 32, and the start button 8 is pressed. When the sensor 49 detects the presence of the movable end section 30 on the positioner, the controller receives the detection signal of the sensor and, after processing, sends a command to the cylinder E29 and the cylinder F2. The telescopic ends of the cylinders E29 and F2 drive the clamping block 31 to clamp the movable end section 30. The telescopic end of the cylinder A15 drives the pressure head 19 and the elastic tip 13 thereon to move downward until the elastic tip enters the center hole 54 of the movable end section handle 52 and the pressure head presses against the upper end surface of the movable end section handle 52 to perform positioning and clamping. The telescopic end of the cylinder B3 drives the slider B48 and the retaining spring push plate 6 thereon to move forward along the single guide rail B. The conformal groove A56 at the front end of the retaining spring push plate (the function of the conformal groove A is to make conformal contact with the retaining spring to ensure the stability of the retaining spring pushing process, so that the retaining spring opening is always facing the retaining spring groove of the movable end section handle, which is convenient for smoothly driving the retaining spring into the retaining spring groove.) contacts the retaining spring and pushes the retaining spring to move forward along the retaining spring supporting plate. Synchronously, the slider A4 and the retaining spring supporting plate thereon move forward along the single guide rail B under the action of the cylinder B3 and the spring. Rail B37 moves forward with slider B, and the circlip supporting plate 5 first contacts the movable end handle and contacts the limiter E47 at the same time. Under the action of cylinder B, the circlip push plate 6 quickly drives the circlip into the circlip groove 55 (the length of the circlip supporting plate is designed so that no matter whether cylinder B moves forward or backward, the circlip supporting plate is always located below the circlip upper column to ensure that the circlip falls onto the circlip supporting plate). The telescopic end of cylinder B3 contacts the limiter D45 at the same time, indicating that the telescopic end of cylinder B has moved into place; cylinder C27 and air cylinder B3 are in contact with the limiter D45 at the same time, indicating that the telescopic end of cylinder B has moved into place. The telescopic end of cylinder D28 drives slider C25 and its connecting plate 23 and retaining spring detection plate 22 to move forward. The accompanying groove B51 on the front of the retaining spring detection plate contacts the retaining spring, but does not contact the limiter A24, indicating that the retaining spring is in the retaining spring groove. The telescopic ends of cylinders C and D drive slider C and its connecting plate and retaining spring detection plate back, and return to their original position when they contact the limiter B26. Synchronously, cylinder B drives slider B and its retaining spring push plate back, and returns to its original position when it contacts the limiter C46. Slider A and its The retaining ring supporting plate on the upper part returns to its original position along with the slider B under the action of the spring, the telescopic end of the cylinder A drives the pressure head and the elastic top on it to return to their original position, the telescopic ends of the cylinder E and the cylinder F drive the clamping block to return to their original position, remove the movable end section, and then place the next movable end section into the positioner, press the start button to start the next cycle... If there is no retaining ring in the retaining ring groove, the telescopic ends of the cylinders C and D will contact the limiter A24, indicating that the retaining ring is not in the retaining ring groove, and the sound and light alarm 14 will alarm, notifying the operator to handle it.

[0033] For mobile end sections of different heights, a suitable distance is required between skateboard A17 and skateboard B21. By turning the handwheel A35 to drive the screw A43 to rotate in the nut A fixedly connected to the back of skateboard A, the up and down position of skateboard A can be adjusted; similarly, by turning the handwheel B34 to drive the screw B41 to rotate in the nut B fixedly connected to the back of skateboard B, the up and down position of skateboard B can be adjusted.

[0034] Electronic equipment requiring shielding and protection is installed in an electrical cabinet. The controller's human-machine interface is a touchscreen 9, located on the cabinet's surface or mounted on the machine frame. This touchscreen allows on-site personnel to control the machine's operation and adjust various parameters. An audible and visual alarm on the machine frame or cabinet indicates the operating status of the automatic assembly and testing machine for the circlip at the drive shaft's movable end section, or provides an audible alarm for any malfunctions.
