For ease of illustration, a three-dimensional coordinate is shown in FIG. 3, in which the x-axis represents the axial direction, the y-axis represents the transverse direction, and the z-axis represents the vertical direction. In this coordinate system, the direction of the x-axis arrow is forward, the opposite direction of the x-axis arrow is backward, the direction of the z-axis arrow is upward, and the opposite direction of the z-axis arrow is downward.

The equipment comprises an arrangement feeding device 100, a main shaft 200, a chuck 210, slide carriages 300, 301, a tool rest and a mechanical arm 400. The spindle 100 is provided on the base 500 and rotated by a motor, and the chuck 210 is mounted on the front end of the spindle 200 to rotate with the spindle. The carriage 300 is also provided on the base 500, and the blade holder 301 is provided on the carriage 300. The base, the main shaft, the chuck, the slide carriage and the tool rest form a lathe, according to the lathe, a workpiece is clamped by the clamping force of the chuck, the main shaft drives the workpiece to rotate, the drill bit is installed on the tool rest, the slide carriage drives the tool rest to move transversely and change positions, the drill bit is moved to be coaxial with the main shaft, and then the tool rest is moved axially to feed or withdraw a tool, so that a hole can be drilled on the workpiece.

On the basis of the lathe, the arrangement feeding device 100 and the manipulator 400 are arranged, and the electric control system controls the slide carriage, the manipulator, the main shaft, the chuck and the gas injection type rotary oil hydraulic cylinder to coordinate to realize automatic feeding and automatic processing. The electric control system controls the supporting plate, the mechanical arm, the main shaft, the chuck and the gas injection type rotary oil hydraulic cylinder to control the power of the supporting plate, the mechanical arm, the main shaft, the chuck and the gas injection type rotary oil hydraulic cylinder (such as a servo motor, a pneumatic cylinder, an oil hydraulic cylinder, a control valve and the like), so that the supporting plate, the mechanical arm, the main shaft, the chuck and the gas injection type rotary oil hydraulic cylinder can be controlled to accurately act.

The arrangement feeding device 100 is composed of a vibration disk 110 and a groove-shaped rail 120 extending obliquely downward from the vibration disk, and when in operation, the ferrules are stacked in a hopper of the vibration disk, and the ferrules are arranged and roll in the rail from top to bottom as shown in fig. 13-15 under the vibration of the vibration disk, and the lower end of the rail 120 is provided with a baffle plate 121, and the position of one ferrule depending on the baffle plate is determined, so that the ferrules can be accurately clamped by a manipulator. In order to facilitate the manipulator to accurately clamp the workpiece, a notch 122 is formed in the side surface of the lower end of the rail, and the manipulator can clamp the ferrule through the notch. The vibration plate 110 is fixed to the first holder 111 in view of the high position of the vibration plate.

As shown in fig. 5-7 and fig. 13-15, the robot 400 is composed of a finger clamp cylinder 410 and three inward-expanding 411 claws, and the three inward-expanding claws are radially expanded or contracted by the finger clamp cylinder. Accordingly, the three closed inner expansion claws are extended into the axial inner hole of the ferrule as shown in fig. 14, and then the finger clamp cylinder drives the inner expansion claws to radially expand the ferrule, so that the ferrule can be taken away. When the ferrule is sent to a position, such as to and clamped by the V-shaped jaws described below, the finger clamp cylinder radially draws the three inward-expanding jaws together to release the ferrule. Thus, the robot can pick up the ferrule from the rail of the alignment feeder and feed the ferrule to the V-shaped jaws on the chuck.

The V-shaped jaws 211 are arranged in view of the radial holes to be made in the ferrule, which are not suitable for directly clamping the ferrule, i.e. the V-shaped jaws are arranged for clamping the ferrule. Therefore, as shown in fig. 5-9 and fig. 11-12, the chuck 210 is a two-jaw chuck, and a pair of V-shaped jaws 211 are mounted on the chuck, and the V-shaped jaws clamp the ferrule by the clamping force of the chuck, and the axis of the ferrule is perpendicular to the axis of the spindle when the V-shaped jaws clamp the ferrule.

Further, the manipulator 400 is driven by an index motor 420 (stepping motor) to rotate so as to rotate the ferrule gripped by the manipulator around the axis of the ferrule, and after one radial hole is machined, the ferrule is rotated by an included angle β by the index motor, and another radial hole is machined.

In order to be able to grasp and convey the ferrule, particularly based on the posture of the ferrule in the rail, when the ferrule is taken from the rail clamp to the V-shaped jaws by the robot, the V-shaped jaws are initially arranged such that the axial direction of the ferrule when the ferrule is gripped by the V-shaped jaws is transverse, that is, the pair of V-shaped jaws are arranged vertically symmetrically with their V-shaped grooves 212 facing each other, so that the ferrule can be fed between the V-shaped grooves of the pair of V-shaped jaws from the transverse direction. To ensure the precise location of the radial hole, a locating plate 213 is set on the side of the V-shaped pawl away from the inner expanding pawl to locate the ferrule.

In order to transversely clamp and convey the ferrule between the V-shaped grooves of the V-shaped jaws, the inner expansion jaw 411 is positioned on one transverse side of the V-shaped jaws 211 so as to avoid the interference of a chuck and a track; the indexing motor 420 is driven by a transverse cylinder 430 to move transversely, so that the transverse movement of the manipulator is realized; the transverse cylinder 430 is driven by a vertical cylinder 440 to move vertically to realize the vertical movement of the manipulator, and the vertical cylinder 420 is fixed on the second bracket 441. The transverse movement and the vertical movement ensure the smooth and accurate movement of the sliding rail. Accordingly, the inner expanding claw of the manipulator can move vertically and horizontally and is used for extending into the inner hole of the ferrule to radially expand the ferrule. The inner expanding claw moves back and forth between a first position and a second position through vertical and horizontal movement so as to grab and convey the ferrules one by one, wherein the first position is a position for grabbing the ferrules from the arrangement feeding device, and the second position is a position for conveying the ferrules to the V-shaped clamping claws.

The ferrule clamped by the V-shaped jaws is discharged to the downstream of the equipment after the machining is finished, for this purpose, as shown in fig. 10, an air pipe 220 is arranged in the spindle 200 along the axial direction of the spindle, the front end of the air pipe extends to the chuck and points to the ferrule to be machined, after the ferrule is machined, the V-shaped jaws release the ferrule, and the ferrule is blown away by air flow from the air pipe. In order to guide the blown ferrule, a receiving groove or a receiving pipe is arranged, and the ferrule is blown into the receiving groove or the receiving pipe by air flow and is guided out of the device.

Specifically, the rear end of the main shaft 200 is provided with a gas injection type rotary oil hydraulic cylinder 230, the gas injection type rotary oil hydraulic cylinder comprises a first part 231 and a second part 232 which rotate relatively, the first part 231 is connected to the rear end of the main shaft 200 and rotates along with the main shaft, the first part is connected with the chuck 210 through a pull pipe 240, and the gas injection type rotary oil hydraulic cylinder drives the pull pipe to move axially to enable the chuck to clamp or loosen a ferrule with a V-shaped jaw. The second part 232 of the gas injection type rotary oil pressure cylinder is provided with an external gas injection port 233 and a hydraulic oil port 234, and the second part is kept fixed during operation.

The air pipe 220 is positioned in the pull pipe 240, the rear end of the air pipe 220 is connected with the first part 231 of the air injection type rotary oil hydraulic cylinder through the adapter 221, the front end of the air pipe 220 is connected with the air nozzle 222 pointing to the ferrule to be processed, and the air nozzle 222 is fixed relative to the chuck. Therefore, the gas injection channel of the gas injection type rotary oil pressure cylinder is communicated and can deliver gas to the gas nozzle. When the gas injection type rotary oil hydraulic cylinder works, the first part of the gas injection type rotary oil hydraulic cylinder, the adapter, the gas pipe, the gas nozzle, the pull pipe, the main shaft, the chuck and the V-shaped clamping jaws rotate together.

The working steps of the ferrule radial hole machining equipment are as follows:

1. the ferrules are poured into a vibrating tray where they are aligned and rolled from top to bottom in a track as shown in fig. 13-15, with one ferrule at the lower end of the track positioned against the stop 121 and corresponding to the notch 122. The manipulator 400 is driven by the vertical cylinder to move vertically to the height corresponding to the gap (see fig. 13), and then the manipulator is driven by the transverse cylinder to move transversely to enable the inner expanding claw to extend into the axial inner hole of the ferrule to reach the first position (see fig. 14).

2. The finger clamping cylinder enables the three inner expansion claws to radially expand the ferrule, so that the ferrule is clamped (or called as grabbing); the manipulator is carried with the ferrule to be moved laterally away from the track in turn by the lateral cylinder as shown in fig. 15 and is carried with the vertical cylinder to be moved vertically down to a height corresponding to the V-shaped jaw as shown in fig. 5. After one ferrule at the lower end of the track is clamped away, other ferrules arranged in the track automatically move downwards to fill the position.

3. The transverse cylinder carries the robot arm to move transversely to feed the ferrule between the V-shaped grooves of the V-shaped jaws, and one end face of the ferrule is positioned against the positioning plate to a second position (see fig. 6).

4. The gas injection type rotary oil hydraulic cylinder acts, the chuck drives the V-shaped clamping jaws to clamp the ferrule through a pipe pulling, the finger clamping cylinder drives the inner expanding jaws to loosen the ferrule, and the transverse cylinder drives the manipulator to transversely move away from the V-shaped clamping jaws (see figure 7).

5. The main shaft drives the ferrule to rotate under the driving of the motor, the drill bit is driven by the slide carriage to move so that the drill bit is coaxial with the main shaft, and the drill bit is fed to the ferrule through the slide carriage, so that the small-diameter hole of the first radial hole can be drilled. Because the first radial hole is a stepped hole, after the small-diameter hole 602 is machined, the slide carriage drives the drill to retract, and then the other larger drill is moved to be coaxial with the main shaft and fed, so that the large-diameter hole 603 of the first radial hole can be machined.

6. After the large-diameter hole of the first radial hole is processed, the slide carriage drives the drill bit to retract; stopping the rotation of the main shaft; the V-shaped jack catch is restored to the initial state; the transverse cylinder drives the manipulator to move transversely to enable the inner expanding claws to extend into the axial inner holes of the ferrules, and the finger clamping cylinder enables the three inner expanding claws to expand radially to expand the ferrules radially; the gas injection type rotary oil hydraulic cylinder acts to enable the V-shaped clamping jaw to loosen the ferrule; the transverse oil cylinder drives the mechanical arm to move transversely to move the ferrule away from the V-shaped clamping jaw.

7. The indexing motor drives the finger clamp cylinder to rotate by an included angle beta; repeating the action of the step 3; then the gas injection type rotary oil hydraulic cylinder acts, and the chuck drives the V-shaped clamping jaw to clamp the ferrule through pipe drawing; the finger clamping cylinder enables the inner expanding claw to loosen the ferrule, and the transverse cylinder drives the manipulator to reset to the first position to clamp the subsequent ferrule to be processed.

8. The main shaft drives the ferrule to rotate under the driving of the motor, the drill bit is driven by the slide carriage to move so that the drill bit is coaxial with the main shaft, and the drill bit is fed to the ferrule through the slide carriage, so that a second radial hole can be drilled.

9. After the second radial hole is processed, the slide carriage drives the drill bit to retract; stopping the rotation of the main shaft; the V-shaped jack catch is restored to the initial state; the gas injection type rotary oil hydraulic cylinder acts to enable the V-shaped clamping jaw to loosen the ferrule; the ferrule is blown away by the air flow emitted by the air nozzle. In the working process, the air nozzle can spray air all the time, so that the V-shaped clamping jaw can be ensured to be clean, and the drill bit can be cooled.

Repeating the steps 2-9, two radial holes can be processed on the ferrule one by one. It is foreseen that when the number, location, configuration of the radial holes of the ferrule are changed, the machining may be accomplished by adjusting the foregoing steps.
