Description

Technical Field

[0001] The utility model relates to an intermediate shaft shock absorber assembly machine, which is a device for assembling a shock absorber on an intermediate shaft of a constant velocity universal joint transmission shaft of a car. Background Art

[0002] A car's constant velocity universal joint drive shaft consists of a fixed end joint, an intermediate shaft, and a movable end joint. The fixed end joint is directly connected to the car's wheel hub, while the movable end joint is directly connected to the engine's differential. Engine power is transmitted to the wheels through the differential, the movable end joint, the intermediate shaft, the fixed end joint, and the wheel hub, thereby driving the wheels. During the drive shaft assembly process, the installation of the shock absorber on the intermediate shaft is crucial. The position of the shock absorber, in particular, directly affects the performance of the drive shaft. Improper placement of the shock absorber will cause the intermediate shaft to vibrate and shimmy, resulting in abnormal drive shaft noise, reduced performance, and customer dissatisfaction. Traditionally, the installation of shock absorbers on intermediate shafts has been manual, with operators manually attaching the shock absorber to the intermediate shaft. This labor-intensive and inefficient process also resulted in poor assembly positioning, requiring rework and impacting delivery. Therefore, a machine is needed on the assembly site that can free up labor, improve assembly efficiency, and ensure 100% assembly quality. Summary of the Invention

[0003] The purpose of the utility model is to provide an intermediate shaft shock absorber assembly machine. Using this technology, the shock absorber of the intermediate shaft can be automatically assembled online and the assembly quality is 100% guaranteed. Not only is the assembly efficiency high, the labor intensity of the operator is reduced, and the assembly result is reliable.

[0004] The technical solution of the utility model is: an intermediate shaft shock absorber assembly machine includes a frame, a frame, a vertically arranged double guide rail and a single guide rail are fixed on the frame, a horizontal plate, a positioning plate, a fixing plate, a sensor A, a sensor B, a beam sensor A, and a beam sensor B are also fixed on the frame, a longitudinal slide A with a sliding connection is installed on the double guide rail, a connecting block and a sensing head are fixed on the longitudinal slide A, the horizontal plate is located above the double guide rail, a cylinder is installed on the horizontal plate, the telescopic end of the cylinder is fixedly connected to the connecting block through a coupling, the lower end of the connecting block is fixedly connected to a cylindrical pressure cylinder, the The double guide rails are equipped with a longitudinal slide B with a sliding connection, which is located below the longitudinal slide A. A clamping cylinder is fixedly connected to the longitudinal slide B, and the movable end of the clamping cylinder is fixedly connected to the rubber clamping block. The positioning plate is placed below the double guide rails, and a rubber locator is fixedly connected to the positioning plate. The single guide rail is located below the positioning plate. A transverse slide with a sliding connection is installed on the single guide rail, and a positioning block is fixedly connected to the transverse slide. The opposing sensors A and B are arranged above both sides of the rubber locator, and the sensors A and B are arranged on the sides of the double guide rails.

[0005] The center line of the cylindrical pressing cylinder, the center line of the rubber clamping block, the center line of the rubber positioner and the center line of the positioning block coincide with each other.

[0006] The frame is fixedly equipped with a bearing seat and a handwheel driver A. A screw is installed in the bearing seat. One end of the screw is rotatably connected to the bearing seat, and the other end is engaged with the bevel gear on the handwheel driver A through a bevel gear. A spirally connected nut is installed on the screw, and the nut is fixedly connected to the longitudinal slide B.

[0007] The fixed plate is fixedly provided with a handwheel driver B, and the lead screw in the handwheel driver B is spirally connected to the nut in the horizontal slide to adjust the position of the horizontal slide.

[0008] The frame is fixed with a touch screen, a safety light grid, and an audible and visual alarm. The left side of the frame is equipped with an electric control cabinet, which contains a controller. The touch screen is provided with a start button and an emergency stop switch. The touch screen, safety light grid, audible and visual alarm, start button, and emergency stop switch are electrically connected to the controller through a signal line.

[0009] The principle of this utility model is that the cylindrical pressure cylinder at the telescopic end of the cylinder presses the intermediate shaft, which passes through the inner hole of the shock absorber on the rubber positioner, against the positioning block. Sensor B and the induction head automatically determine whether the intermediate shaft is pressed into place. At the same time, mechanical error prevention, that is, the distance between the rubber positioner and the positioning block, ensures that the shock absorber is installed in place. Not only does this improve assembly efficiency, free up labor and reduce operator labor intensity, but the assembly result is 100% reliable.

[0010] The advantages of this utility model are that it can ensure the assembly quality of the intermediate shaft shock absorber through mechanical and electrical error proofing, freeing up labor, improving production efficiency, reducing costs, and reducing the labor intensity of operators, while ensuring 100% assembly quality. In the past, the installation of shock absorbers on intermediate shafts was manual, with operators manually attaching the shock absorbers to the intermediate shafts. This was labor-intensive and inefficient, and due to human factors, the shock absorber assembly position was sometimes not up to standard, requiring rework and affecting delivery. The utility model solves these problems, achieving automatic assembly, increasing customer satisfaction, and enhancing the core competitiveness of enterprises. BRIEF DESCRIPTION OF THE DRAWINGS

The single guide rail 31 is located below the positioning plate 4, and the single guide rail 31 is provided with a slidingly connected transverse slide 33, and the transverse slide 33 is fixedly connected with a positioning block 32. The said beam sensor A9 and beam sensor B29 are provided on both sides of the rubber positioner 5 and are higher than the rubber positioner (5). Their function is to detect whether there is a shock absorber 36 and an intermediate shaft 37. The said sensor A24 and sensor B25 are provided on one side of the double guide rail 14. The function of sensor A24 is to cooperate with the sensing head 23 to sense the longitudinal slide A16 to return to its position, and the function of sensor B is to cooperate with the sensing head 23 to sense that the lower end of the intermediate shaft 37 contacts the positioning block 32 to be in place.

[0022] The center line of the cylindrical pressing cylinder 15 , the center line of the rubber clamping block 10 , and the center line of the rubber positioner 5 are on the same straight line and are opposite to the positioning block 32 .

[0023] The frame is fixedly mounted with a bearing seat 26 and a handwheel driver A30. Bearing seat 26 is rotatably connected to one end of a lead screw 28. The bevel gear at the other end of lead screw 28 meshes with the bevel gear on handwheel driver A30. A screw nut 27 is mounted on lead screw 28 and fixedly connected to longitudinal slide B12.

[0024] A handwheel driver B34 is fixedly mounted on the fixed plate 1 . The lead screw in the handwheel driver B34 is screw-connected to the nut in the horizontal slide 33 , and its function is to adjust the position of the horizontal slide 33 .

[0025] The frame is fixed with a touch screen 8, a safety light grid 2, and an audible and visual alarm 21. The left side of the frame is equipped with an electric control cabinet 11, which contains a controller. The touch screen is provided with a start button 6 and an emergency stop switch 7.

[0026] The utility model intermediate shaft vibration damper assembly machine is provided with an automatic control system, which includes a controller and a plurality of cylinders and sensors that undertake different tasks. The corresponding sensors are installed in the units corresponding thereto. An electric control cabinet 11 is installed on the left side of the frame, and the controller is installed in the electric control cabinet.

[0027] The working process of the present invention is as follows: the distance between the positioning block 32 and the rubber positioner 5 is set in advance, that is, the installation position of the shock absorber 36 on the intermediate shaft 37 is determined, and the setting plays a role in mechanical error prevention. Press the start button 6, put the shock absorber 36 into the rubber positioner 5, insert the designated end of the intermediate shaft 37 into the shock absorber 36, and push the intermediate shaft 37 against the rubber clamping block 10. When the opposing sensor B29 detects the presence of the shock absorber 36 and the opposing sensor A9 detects the presence of the intermediate shaft 37, the telescopic end of the clamping cylinder 13 drives the rubber clamping block 10 to retract and clamp the intermediate shaft 37, so that the intermediate shaft is radially positioned. The telescopic end of the cylinder 19 drives the connecting block 17 fixed to the longitudinal slide A16 downward through the coupling 20, and simultaneously drives the longitudinal slide A16 downward along the double guide rails 14, and simultaneously drives the cylindrical pressure cylinder 15 at the lower end of the connecting block downward, pushing the intermediate shaft 37 downward until the lower end of the intermediate shaft 37 contacts the positioning block 32. At this time, the sensor B25 senses the sensing head 23, indicating that the lower end of the intermediate shaft 37 has contacted the positioning block 32, and at the same time, the shock absorber 36 When it reaches the installation position on the intermediate shaft 37, cylinder 19 drives longitudinal slide A16 back, and sensor head 23 reaches the position of sensor A24, indicating that longitudinal slide A16 has returned to its position. The drive shaft with the shock absorber 36 assembled is removed, and another shock absorber is installed and inserted into another intermediate shaft to assemble the next shock absorber. For drive shafts of different lengths, the handwheel driver A30 can be rotated to drive the lead screw 28, which drives the nut 27 and the longitudinal slide B12 connected to it to move up and down along the dual guide rails 14 to set the position of longitudinal slide B12. Alternatively, the handwheel driver B34 can be used to adjust the transverse slide 33 and its positioning block 32 to move up and down along the single guide rail 31 to set the position of positioning block 32 to accommodate intermediate shafts of different lengths. The rubber positioner 5 can be replaced to accommodate intermediate shafts of different diameters.
