Description

Technical Field

[0001] The invention belongs to the technical field related to parts finishing, and specifically discloses a shaft parts processing device. Background Art

[0002] Shafts are among the most fundamental and important mechanical components in mechanical engineering. These are rotating parts whose length is greater than their diameter, used to support rotating parts (such as gears, pulleys, and couplings) and transmit motion and torque. Their primary function is to bear loads, transmit motion and power, and play a crucial supporting and transmission role in various types of mechanical equipment. They are widely used in numerous fields, including automobiles, machine tools, aerospace, shipbuilding, metallurgy, and mining. For example, a car's drive shaft transmits engine power to the wheels; a machine tool's spindle supports and rotates the cutting tool to perform cutting operations; and a motor shaft connects the rotor to the load, transmitting electromagnetic torque. Turning is the primary process in shaft machining, used to machine surfaces such as the outer diameter, end faces, and threads, ensuring dimensional accuracy, including diameter and length, and surface roughness.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-11The shaft parts processing device shown in the figure includes a base 1, a spindle box 3 is provided on one side of the upper end surface of the base 1, a hydraulic caliper 4 is installed on the end of the spindle box 3, a turning frame 2 is provided on the upper end surface of the base 1 and on one side of the spindle box 3, a slide 11 is connected to the turning frame 2 on one side through an X-axis drive slide mechanism 9, a double-axis adjustment seat 12 is provided on the upper end of the slide 11, a mounting seat 13 is fixedly connected above the double-axis adjustment seat 12, and a tool holder 7 is connected to the upper end surface of the mounting seat 13 through a mounting block 29. A tailstock 8 is fixedly installed above one end of the cutting frame 2, a cutting block 15 is installed inside the tool holder 7, and an outer wall of one side of the tool holder 7 is connected to a rotary joint 44 through a transmission mechanism. A negative pressure pump 35 is provided on the outer wall of the tool holder 7 and located at the rotary joint 44. The rotary joint 44 is rotatably sleeved on the port of the negative pressure pump 35. The end of the rotary joint 44 away from the negative pressure pump 35 is connected to a rotating tube 33. Adsorption mechanisms are arranged at equal distances along the circumferential direction inside the rotating tube 33. Chip suction buckets 18 are symmetrically installed at both ends of one side of the outer wall of the tool holder 7. See the instructions attached Figure 1 and Figure 2 It can be seen that the X-axis drive slide mechanism 9 can be a combination of a linear guide and a servo motor to drive the slide 11 to move horizontally, driving the tool holder 7 to move synchronously to complete the basic turning operation; The hydraulic caliper 4 is used to clamp one end of the slender shaft and cooperate with the spindle box 3 to drive the workpiece to rotate, while the tailstock 8 provides auxiliary support.

[0021] The transmission mechanism includes a second motor 30 disposed on the outer wall of one side of the tool holder 7. The output end of the second motor 30 is connected to the rotary joint 44 via a connected pulley assembly 27. An L-shaped block 32 is provided on the outer edge of one side of the tool holder 7 near the top. The output end of the second motor 30 rotates and is inserted into the interior of the L-shaped block 32. See the instructions attached Figure 3 and Figure 4 It can be seen that the second motor 30 drives the rotary joint 44 to rotate via the pulley assembly 27 , and the corresponding rotary tube 33 rotates synchronously, and the L-shaped block 32 lifts and supports one end of the second motor 30 .

[0022] The adsorption mechanism includes a winding tube 34 that is connected and installed inside the rotating tube 33 at equal distances in the horizontal direction, and a card shell 43 is commonly sleeved on one end of the outer side of the multiple winding tubes 34. Support seats 38 are provided on the outer edges of the upper and lower ends of the card shell 43. Multiple groups of chip rotating mechanisms are symmetrically arranged inside the two support seats 38. The multiple groups of chip rotating mechanisms include a rotating shaft 40 rotatably installed inside the support seat 38. Rotating spline blades 41 are installed on the upper and lower sides of the rotating shaft 40. A gear 42 is fixedly sleeved on the lower side of the rotating shaft 40. A rack 39 is slidably inserted into one side of the support seat 38. The rack 39 is meshed with the gear 42. A push block 37 is fixedly installed on the side of the rack 39 away from the gear 42. A reciprocating cylinder 36 is provided on the outside of the push block 37. A triangular disc 26 is installed at the end of the rotating tube 33. One end of the reciprocating cylinder 36 is fixedly installed on the outside of the triangular disc 26. See the instructions attached Figures 6-11 As can be seen, when the rotating tube 33 rotates, the multiple winding tubes 34 and the clamping shell 43 rotate accordingly. The winding tubes 34 can bring the cutting block 15 to the long chips above for winding. In addition, the rotating tube 33 is connected to the negative pressure pump 35, which enables the winding tubes 34 to absorb the long chips during rotation to prevent the long chips from winding around the outer surface of the workpiece. Then the reciprocating cylinder 36 drives the rack 39 to reciprocate by pushing the push block 37, and the meshing gear 42 drives the rotating shaft 40 and the rotating spline blade 41 to rotate at a high frequency to shear the long chips; The triangular disc 26 stably supports the drive of the reciprocating cylinder 36 at one end of the rotating tube 33 .

[0023] An air inlet is provided inside the two sets of chip suction buckets 18 on the side close to each other, and the outer surfaces of the chip suction buckets 18 on the side close to each other are arranged in an inclined surface. The upper parts of the two chip suction buckets 18 are connected by a commonly connected U-shaped tube 31. One end of the U-shaped tube 31 is connected to the suction pipe 28, and the end of the suction pipe 28 away from the U-shaped tube 31 is connected to the negative pressure suction mechanism 10. The negative pressure suction mechanism 10 is arranged on the upper end surface of the dual-axis adjustment seat 12; See the instructions attached Figure 5 It can be seen that the two chip suction buckets 18 are designed with inclined surfaces. The cut chips are connected through the negative pressure suction mechanism 10, the suction pipe 28 and the U-shaped tube 31, forming a negative pressure airflow in the local area of ​​the chip suction bucket 18 to absorb the chips.

[0024] The outer wall of the front end of the tool holder 7 is symmetrically provided with connecting rods 20, and the ends of the two connecting rods 20 are jointly installed with a cross frame 6. A screw rod 17 is rotatably installed at the bottom of the cross frame 6. A No. 1 motor 22 is provided at one end of the screw rod 17. The two ends of the outer side of the screw rod 17 are respectively threaded with a stabilizing clamping rod 5, and the inner side of the stabilizing clamping rod 5 close to each other is provided with an arc groove 23 adapted to the shaft workpiece. A plurality of universal balls 21 are rotatably embedded in the arc groove 23. A connecting pipe 24 is installed on the outer wall of one side of the stabilizing clamping rod 5. A cooling air blow pipe 25 is installed at one end of the connecting pipe 24. The internal threaded surface of the stabilizing clamping rod 5 is symmetrically arranged. The outer wall of the upper end of the stabilizing clamping rod 5 slides in contact with the inside of the cross frame 6. A baffle 14 is provided on one side of the outer wall of the spindle box 3, and one end of the cross frame 6 slides inside the baffle 14. See the instructions attached Figure 3-Figure 5 As can be seen, the No. 1 motor 22 drives the two stabilizing clamping rods 5 to move toward each other until the universal ball 21 inside the arc groove 23 fits the outer surface of the overhanging workpiece, providing a stable support force for the middle section of the workpiece during turning operation, ensuring that the workpiece will not vibrate excessively due to the grinding of the tool block 15, resulting in chatter marks on the workpiece surface. The universal ball 21 can provide its own degree of freedom when the cross frame 6 moves with the tool holder 7 and the hydraulic caliper 4 drives the workpiece to rotate, avoiding clamping interference; The cooling air blowing pipe 25 can be connected to an external cooling fan or other device through the connecting pipe 24. During the workpiece processing, the cooling air flow can be sprayed on the outer surface to prevent the workpiece from being overheated and deformed.

[0025] The tool holder 7 is symmetrically slidably mounted with a slide 16 below one side of the chip suction bucket 18, and a collection box 19 is mounted on the upper end surfaces of the two slides 16; See the instructions attached Figure 3 It can be seen that the collection box 19 is located at the lower end of the workpiece and the tool block 15, and can collect some of the debris that falls. The two slides 16 can be slid out from one end of the tool holder 7, and the debris can be processed collectively afterwards.

[0026] Working principle: The slender shaft workpiece is clamped at one end by the hydraulic caliper 4, and the other end is freely suspended. The No. 1 motor 22 is started to drive the screw 17 to rotate, which drives the two stabilizing clamping rods 5 to move toward each other along the inside of the cross frame 6 until the universal ball 21 in the arc groove 23 flexibly contacts the outer surface of the workpiece, providing support for the overhang section for subsequent processing; The X-axis driving slide mechanism 9 drives the tool holder 7, the cross frame 6, and the adsorption mechanism to move synchronously with the tool block 15 to perform turning on the workpiece. The spindle box 3 drives the workpiece to rotate by driving the hydraulic caliper 4. The tool block 15 is fed by the movement of the tool holder 7, thereby performing turning operations. The long chips brought out from the outer surface of the turning workpiece are guided upward by the inclined surface of the tool block 15 and enter between the chip suction buckets 18 on both sides of the outer wall of the tool holder 7. The negative pressure suction mechanism 10 exhausts the inside of the chip suction bucket 18 through the suction pipe 28 and the U-shaped tube 31 to form a local negative pressure air field. At the same time, the No. 2 motor 30 drives the rotary joint 44 to rotate through the pulley assembly 27, thereby driving the rotating tube 33 and the internal winding tube 34 to rotate at high speed. The adsorption ports distributed circumferentially around the winding tube 34 cooperate with the negative pressure pump during rotation. 35, enhance the suction force on the chips, and wind the long chips around the winding tube 34, the triangular disc 26 at the end of the rotating tube 33 drives the reciprocating cylinder 36 to perform reciprocating motion, and the telescopic end of the reciprocating cylinder 36 pushes the push block 37, so that the rack 39 slides back and forth in the support seat 38, and the rack 39 is engaged with the gear 42, driving the rotating shaft 40 and the rotating spline blade 41 to rotate at a high frequency, shearing and crushing the long chips wound on the winding tube 34 to form debris, and the crushed debris is adsorbed by the chip suction bucket 18 and falls into the chip suction bucket 18 for temporary storage, and some debris falls into the collection box 19 below. In this way, the accuracy and reliability of the slender shaft turning process can be greatly improved. After the processing is completed, the No. 1 motor 22 flips and drives the stabilizing clamping rod 5 to release the workpiece, and the workpiece can be taken out.

[0027] The basic principles, main features and advantages of the present invention are shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
