Description

Technical Field

[0001] The present invention relates to the technical field of rotary shaft processing, in particular to a forming machine tool for processing a hydraulic motor rotary shaft. Background Art

[0002] As the core component of power transmission, the dimensional accuracy and end surface quality of the hydraulic motor shaft directly determine the sealing and transmission efficiency of the motor.

[0003] The current industry generally adopts a step-by-step processing model: operators must first cut long shaft blanks into segments according to preset lengths on a lathe, then disassemble and transfer them to independent grinding equipment for end face deburring. This traditional process has systemic flaws: manual adjustment of the cutting spacing can easily lead to inconsistent lengths of multiple shaft segments due to scale errors and visual deviations, resulting in large cumulative tolerances and seriously affecting the concentricity of multi-axis parallel assembly. More importantly, the blanks undergo axial movement during the cutting process due to the lack of multi-point dynamic locking, resulting in oblique burrs or microcracks in the cut. The separation of the process steps also leads to repeated clamping, often requiring multiple positioning cycles for a single shaft. This not only prolongs the processing cycle but also causes coaxial deviations due to datum plane conversion. In addition, the high-speed rotating disc blades generate high-temperature metal debris that scatters radially, posing a risk of burns to the operator. The metal debris scattered on the ground must be manually cleaned, polluting the workshop environment. To this end, we propose a forming machine tool for hydraulic motor shaft processing.

[0015] The present invention provides a forming machine tool for processing a hydraulic motor shaft. It has the following beneficial effects: This hydraulic motor shaft processing forming machine uses the second electric telescopic rod in the distance adjustment component to drive the cross long rod to synchronously adjust the spacing of all the first sliding blocks, so that the disc blade is accurately positioned to the evenly divided cutting point of the shaft blank. The connecting rod rigidly pulls the supporting assembly to move equidistantly, ensuring that the cutting point is always located in the center of the support rod gap. The spring preloads the supporting wheel to form elastic contact. When the movable seat moves toward each other to the spring compressed state, it turns into rigid support, and cooperates with the pressure roller to form a three-point extrusion pressure, which completely eliminates the vibration offset of the blank, thereby ensuring the consistency of the length of multiple shaft sections and the flatness of the incision. This forming machine tool for processing hydraulic motor shafts adopts an integrated knife-grinding structure. Grinding discs are coaxially fixed on both sides of the disc blade. After cutting is completed, the blade continues to move downward, and the grinding disc instantly polishes the end face of the cut. The intelligent trigger system uses the transmitter and receiver group to coordinate control to trigger the protective box to open and descend in stages, close the protective box to block debris, and activate the pressure roller to drive the blank to rotate, so as to achieve comprehensive grinding of the cut surface. The slitting and end face finishing are completed through one clamping, avoiding repeated positioning errors. (3) The hydraulic motor shaft processing forming machine controls the swing arm through the second motor driving gear set, so that the arc-shaped protective box closes and wraps the blade during the cutting and grinding stages, effectively blocking high-speed flying debris. The debris is gathered into the through groove through the arc-shaped inner wall of the protective box and slides into the collection box through the inclined guide plate to achieve closed recycling of waste chips. In the non-operating state, the protective box re-covers the cutting edge when the disc blade rises, eliminating the safety hazard of the equipment standby. There is no human intervention in the debris processing throughout the process, ensuring the cleanliness of the operating environment and the safety of personnel. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the first sliding seat 2 and the second sliding seat 4 are driven to approach each other, and the two ends of the rotating shaft blank 10 are clamped and supported by the electric chuck 3 provided on the first sliding seat 2 and the second sliding seat 4; Then, the second mounting plate 803 is driven downward by the third electric telescopic rod 801, so that the disc blade 806 cuts downward at the cutting point on the rotating shaft blank 10. The cutting point of the disc blade 806 on the rotating shaft blank 10 is located between the two support rods 1506. When the second mounting plate 803 moves downward, the fifth electric telescopic rod 1101, whose fixed end is fixedly connected to the side wall of the second mounting plate 803, is adaptively shortened at the same time, while still maintaining a tight state on the rotating shaft blank 10. When the second mounting plate 803 moves downward, the transmitter provided on the third electric telescopic rod 801 is misaligned with the first receiver 701 provided on the outer wall of the extension rod 802. The laser generated by the transmitter cooperates with the receiver group 7 to trigger an electrical signal, wherein the laser irradiating the receiver group 7 or leaving the receiver group 7 can trigger an electrical signal (the model FU-JGDS-10-30V-M12-NPN can be used). Laser sensor), at this time, the first receiver 701 transmits an electrical signal to the controller, which drives the fourth electric telescopic rod 902 to extend and the second motor 904 to rotate, so that the first gear 905 drives the two second gears 906 to rotate relative to each other, thereby causing the two swing rods 907 to open to both sides. After opening, the protective boxes 908 set at the ends of the two swing rods 907 move downward to both sides of the rotating shaft blank 10. When the outer wall of the disc blade 806 contacts the outer wall of the rotating shaft blank 10 to cut the rotating shaft blank 10, the position of the transmitter and the second receiver 702 corresponds to each other, and the second receiver 702 transmits an electrical signal to the controller (model CPM1A The PLC controller drives the first gear 905 to rotate through the controller so that the two protective boxes 908 are closed. The protective box 908 is set at the cutting point of the disc blade 806 on the shaft blank 10. Under the action of the protective box 908, the waste chips splashed when the disc blade 806 cuts the shaft blank 10 into multiple sections of the hydraulic motor shaft. After the disc blade 806 cuts the shaft blank 10 into multiple sections, the third electric telescopic rod 801 still drives the disc blade 806 to continue to move downward until the height of the transmitter corresponds to that of the third receiver 703. At this time, the grinding disc 807 set at the center of the two side walls of the disc blade 806 is aligned with the shaft blank 10. The end contacts after cutting, and the cutting surface on the shaft blank 10 is ground by the grinding disc 807. When the third receiver 703 is triggered, the third receiver 703 transmits an electrical signal to the controller. Under the action of the controller, the third motor 1104 is turned on, and the third motor 1104 drives the pressure roller 1103 to rotate. When the pressure roller 1103 rotates, the friction between its outer wall and the outer wall of the shaft blank 10 causes the shaft blank 10 cut into multiple sections to rotate synchronously, so that the grinding disc 807 can grind the end face of the shaft blank 10 after cutting more comprehensively. In this process, the protective box 908 can still protect the waste chips generated during grinding.The waste chips are guided by the arc-shaped inner wall of the protective box 908 and then fall from the through slot 909 onto the upper surface of the guide plate 1402. Then, they are guided by the inclined guide plate 1402 and fall into the interior of the collection box 1401. After the hydraulic motor shaft is polished after being cut and formed, the second mounting plate 803 is driven upward by the third electric telescopic rod 801. When the transmitter and the second receiver 702 are misaligned, the controller drives the second motor 904 to rotate so that the two swing rods 907 are opened, and at the same time drives the fourth electric telescopic rod 902 to drive the protective box 908 to move upward. After the disc blade 806 is reset upward, the protective box 908 is located on the outside of the disc blade 806 to cover the disc blade 806, preventing the disc blade 806 from injuring people when not in use. Through the connection of the connecting rod 13, when the distance adjustment component 6 adjusts the cutting component 8, the supporting component 15 can be changed synchronously according to the position of the cutting component 8. The cutting component 8 and the supporting component 15 are always used in conjunction with each other. The hydraulic motor rotating shaft after processing and forming can be taken out in sequence by an external robot.
