Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to a thread processing equipment for automotive piston rod production. Background Technology

[0002] Automotive piston rods are key transmission components that connect pistons to external parts. They are widely used in core components such as engines, shock absorbers, and hydraulic systems. They serve as a bridge for force transmission and motion conversion, and withstand high-frequency alternating loads. In the production process of automotive piston rods, one step is to perform thread machining on their surface. This thread machining process utilizes thread machining equipment from mechanical manufacturing. Traditional automotive piston rod thread processing equipment typically uses thread rolling machines. The core of thread rolling is the cold plastic deformation of metal. Through two threaded rollers, the piston rod surface in a plastic state is subjected to radial extrusion and friction spinning. Under the extrusion force, the workpiece metal undergoes plastic flow and conforms to the roller teeth, ultimately forming a thread that complements the roller teeth. The entire process is chip-free, relying solely on material plastic deformation to complete the thread processing. However, traditional thread rolling machines require operators to load and unload materials, which is time-consuming and reduces production efficiency when processing threads on the surface of automotive piston rods. Therefore, a new type of automotive piston rod thread processing equipment is needed to solve the above problems. Summary of the Invention

[0014] The present invention provides a thread processing equipment for automobile piston rod production, the advantages of which are: When threading an automotive piston rod, the teeth on one side of the moving plate mesh with the first rotating gear, thereby driving the disc to rotate. During the rotation of the disc, the rotating column and the connecting rod work together to drive the second bevel gear to rotate circumferentially outside the first bevel gear, causing the material box on one side of the connecting block to rotate. When the first thread rolling machine returns to its original position, the teeth on one side of the moving plate are exactly at the end, allowing the material box to rotate at the same angle so that the material outlet at the bottom of the material box is perpendicular to the top of the placement seat, facilitating subsequent automatic material feeding. Furthermore, during the rotation of the connecting rod, the rotation of the bevel gear and the main bevel gear drives the distribution roller to rotate. When the material box rotates 90° to the top of the placement seat, the distribution roller also rotates 90° inside the fixed box, causing the car piston rod inside the material trough to fall into the discharge port and then to the top of the placement seat, completing the automatic feeding operation. Furthermore, before the material box rotates, the connecting plate moves back to its original position, driving the rack to move. During this movement, the rack rotates through the second rotating gear. The cooperation of the main and slave synchronous pulleys drives the lead screw to rotate. During this rotation, the lead screw, through its cooperation with the screw sleeve, drives the push plate to move, thereby pushing the first set of car piston rods on the placement seat to one side and sliding them down the discharge guide rail, achieving automatic discharge. The above structure enables automated connection of processing, loading, and unloading. A set of piston rods can be prepared simultaneously during processing, and after processing, unloading and precise loading of new materials are completed automatically. There is no manual operation, no process intervals, and continuous processing can be carried out in cycles, improving work efficiency and making loading and unloading operations more convenient.

[0020] When threading an automobile piston rod, a set of automobile piston rods is first placed on the top of the mounting seat 6. Then, an external power source starts the motor to drive the first thread rolling machine 2 and the second thread rolling machine 4 to rotate. After the first thread rolling machine 2 and the second thread rolling machine 4 rotate, the starting cylinder 3 pushes the first thread rolling machine 2 to one side, so that the first thread rolling machine 2 fits against one side of the automobile piston rod. Then, through the cooperation with the second thread rolling machine 4, the radial extrusion and friction spinning of the first thread rolling machine 2 and the second thread rolling machine 4 cause the automobile piston rod to undergo plastic flow under the extrusion force, fitting the tooth profile of the first thread rolling machine 2 and the second thread rolling machine 4. Finally, a thread complementary to the tooth profile of the roller is formed, completing the threading work on the automobile piston rod. While the first thread rolling machine 2 is processing the first set of automotive piston rods, other automotive piston rods to be processed are placed inside the material box 504. After one set of automotive piston rods is processed, the cylinder 3 is activated to move the first thread rolling machine 2 back. When the first thread rolling machine 2 moves back, it drives the moving plate 5016 at one end of the connecting plate 5019 to move. When the moving plate 5016 moves, it drives the teeth on one side to mesh with the first rotating gear 5018, thereby driving the disc 5017 to rotate. During the rotation of the disc 5017, it drives the rotating column 507 to rotate via a belt. During the process, the connecting rod 509 will rotate. As the connecting rod 509 rotates, it will cause the second bevel tooth 5012 to rotate in a circle outside the first bevel tooth 508. As the second bevel tooth 5012 rotates, it will also cause the connecting block 5014 to rotate to one side. As the connecting block 5014 rotates, it will cause the material box 504 to rotate. When the first thread rolling machine 2 returns to its original position, the teeth on one side of the moving plate 5016 will reach the end. When the teeth of the moving plate 5016 reach the end, the material box 504 will rotate 90° so that the discharge port 5021 at the bottom of the material box 504 is perpendicular to the top of the placement seat 6. During its rotation, the connecting rod 509 also drives the bevel gear 5011 to rotate. The bevel gear 5011, in turn, drives the main bevel gear 5010. The main bevel gear 5010, in turn, drives the main pulley 701. The main pulley 701, in turn, drives the secondary pulley 702 via a belt. The secondary pulley 702, in turn, drives the distributing roller 703. When the material box 504 rotates 90° to the top of the placement seat 6, the distributing roller 703 also rotates 90° inside the fixed box 505, causing the material box 504 to fall onto the piston rod inside the material trough 704, perpendicular to the bottom of the discharge port 5021, and then onto the top of the placement seat 6, completing the automatic feeding process and making feeding more convenient. Before the material box 504 rotates, when the first thread rolling machine 2 returns to its original position after the first processing, the connecting plate 5019 moves to move the rack 5020. During the movement of the rack 5020, it drives the second rotating gear 5027 to rotate. During the rotation of the second rotating gear 5027, it drives the main synchronous pulley 5034 to rotate. During the rotation of the main synchronous pulley 5034, it drives the driven synchronous pulley 5035 to rotate via a belt. By adjusting the main synchronous pulley 5034 and the driven synchronous pulley 5035... The 0.35 transmission ratio allows the synchronous pulley 5035 to rotate faster. During this rotation, the synchronous pulley 5035 drives the lead screw 5033, which in turn drives the lead sleeve 5036. Because the guide groove 5026 uses the push plate 5032 for limiting, the lead sleeve 5036 moves to one side outside the lead screw 5033, thus pushing the first set of automotive piston rods on the placement seat 6 to one side and allowing them to slide down the unloading guide rail 5025, achieving automatic unloading.When the first thread rolling machine 2 is processing the second set of automotive piston rods, it will drive the connecting plate 5019 to move to one side. While the first thread rolling machine 2 is still moving, before the material box 504 has rotated 90°, the rack 5020 has completed its movement. Through its cooperation with the second rotating gear 5027, the lead screw 5033, and the thread sleeve 5036, the push plate 5032 returns to its original position, ready to push away the next set of processed automotive piston rods. When the material box 504... When rotated 90°, the teeth on one side of the moving plate 5016 are in position. At this time, there is still a certain distance between one side of the first thread rolling machine 2 and one side of the placement seat 6. Since the teeth of the moving plate 5016 have completed their movement, the first thread rolling machine 2 will not cause the disc 5017 to rotate when it moves the moving plate 5016 to one side. When the lower feed port 5021 drops the car piston rod, the first thread rolling machine 2 has not yet moved into position. At this time, the limiting plate 5022 on one side of the placement seat 6 is perpendicular to the placement seat 6. On one side, since the position of the second thread rolling machine 4 is fixed, the car piston rod is precisely placed on the top of the placement seat 6 under the guidance of the second thread rolling machine 4 and the limiting plate 5022. As the first thread rolling machine 2 continues to move, the extrusion block 5023 on one side of the first thread rolling machine 2 will contact the extrusion seat 5024, thereby extruding the limiting plate 5022 downward through the inclined surface set on one side of the extrusion seat 5024. When the limiting plate 5022 moves downward, it will drive the spring 5029 at the bottom of the second fixed plate 5030 to be stretched through the first fixed plate 5028. When the first thread rolling machine 2 contacts one side of the car piston rod, the limiting plate 5022 will be squeezed down one step in advance, which will not affect the contact between the first thread rolling machine 2 and the car piston rod, thus completing the guidance of the car piston rod unloading, making it more accurate during unloading. By repeating the above working steps, the automatic feeding and unloading of the car piston rod thread processing can be completed, eliminating the need for manual grooving and making the processing efficiency higher.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
