[0004] When assembling the existing sleeve type end mill, the end blades and side blades need to be installed at the installation positions on the end and side of the milling cutter shank. During the installation, the milling cutter shank needs to be fixed on the clamp first, and then assembled and installed. After installation, the clamp needs to be loosened and the milling cutter shank needs to be rotated a certain angle and then fixed to install the next set of end blades or side blades. The disassembly and assembly are cumbersome during adjustment. For this reason, we propose an automatic assembly device for machine tool tool components to solve the above problems. Summary of the invention

[0008] The middle frame can swing around the turntable. When the middle frame swings backward to a vertical position, the knife handle is released and can be replaced and the rotation angle adjusted. When the middle frame swings forward to a horizontal position, the position of the knife handle is locked. The knife handle can be locked and released by swinging the middle frame 90 degrees, which is convenient for adjustment.

[0009] Preferably, the fixture includes a plug plate that pushes the sliding shaft forward when the middle frame is in a horizontal position, the turntable includes a base, the rear end of the middle frame is hingedly mounted on the top of the base through a pin shaft, the plug plate is fixed to the front of the top of the base, the lower part of the middle frame is provided with a notch that matches the plug plate, the middle part of the sliding shaft is installed with a middle ring, the rear end of the sliding shaft is installed with a permanent magnetic spline head, and the rear part of the middle frame is located at the connecting frame position and is installed with a permanent magnetic active ring;

[0010] When the middle frame swings from a vertical position to a horizontal position, the plug plate pushes the sliding shaft forward through the middle ring. When the middle frame swings to a vertical position, the permanent magnetic adsorption causes the sliding shaft to move downward. The sliding shaft can play a locking role and a stable transmission role at the same time.

[0011] Preferably, a step block is installed at the front end of the sliding shaft, a through hole is opened in the middle of the step block to be slidably assembled and connected with the lock pin relatively forward and backward, the sliding cavity is provided with a limiting portion at the concave position of the lock pin, the two ends of the lock pin are arranged in a hard columnar shape, and the middle part of the lock pin is arranged in a spiral shape;

[0012] The step block moves forward, and the hard columnar structures at both ends of the locking pin can be inserted into the tool handle. When the step block moves backward, the spiral structure in the middle of the locking pin rebounds, and the locking pin only moves horizontally to the left and right to ensure accurate docking with the pin hole of the tool handle.

[0016] The turntable faces the front and the robotic arm faces the right side, so the side blade can be installed. The turntable and the robotic arm rotate forty-five degrees relative to each other, so the end blade can be easily installed. The assembly head can negatively absorb the side blade or end blade and use a batch bit for combined installation.

[0017] Preferably, the telescopic sleeve comprises a fixed outer sleeve and an inner sleeve sliding inside the outer sleeve, the air passage is arranged between the left and right ends of the upper side wall of the inner sleeve, a sealing ring is installed at the left end of the annular inner sleeve, a bushing is installed in the middle of the sealing ring, and the bushing is sleeved and installed on the outside of the motor;

[0018] The inner sleeve rotates with the motor through the sealing ring to rotate and align the side edge or end edge with the installation position of the tool handle. After the alignment is stuck, the sealing ring and the motor rotate relatively, and the motor can rotate and tighten the bolt by itself.

[0019] Preferably, a suction ring with a ring groove is installed at the right end of the inner sleeve, a circular hole corresponding to the airway is opened on the upper part of the suction ring, and the ring groove is in conduction connection with the airway;

[0022] The robotic arm can pick up materials at the discharge port, and before picking up the materials, it shakes the feed rack to make the materials inside slide to the left for automatic feeding.

[0023] Preferably, the second material channels are provided with two front and rear ones, the inner gaps of the two second material channels correspond to the diameters of the side blade and the end blade respectively, and the inner gap of the first material channel corresponds to the diameter of the bolt end head;

[0024] There are two second material channels, one providing side blades and the other providing end blades. The two first material channels provide bolts. During the vibration, the upper bolt can be inserted into the middle hole of the lower side blade or end blade during the sliding process to the left to perform automatic batching.

[0025] Preferably, a bomb rack is installed between the first material channel and the second material channel, and a main frame is installed at the bottom end of the bomb rack;

[0026] The spring rack enables the first material channel and the second material channel to be driven and vibrated more easily, thereby making the first material channel and the second material channel discharge materials more smoothly.

[0027] Compared with the prior art, the advantages of the automatic assembly device for machine tool tool components are:

[0028] 1. Through the setting of the middle frame, the rear end of the middle frame is pin-connected with the turntable and can swing around the pin-connected position. When the middle frame is vertical, the sliding shaft moves downward to retract the locking pin into the sliding cavity. At this time, the tool handle is loosened and can be replaced and the rotation angle can be adjusted. When the middle frame is horizontal, the plug plate pushes the sliding shaft forward to push the locking pin into the pin hole of the tool handle on both sides to lock the position of the tool handle. The tool handle can be locked and released by swinging the middle frame 90 degrees, which is convenient for adjustment.

[0029] 2. Through the setting of the assembly head, when the manipulator takes the material, the negative pressure of the telescopic sleeve fixes the side blade or end blade at the end of the assembly head. When the manipulator moves, the side blade or end blade can rotate with the bit. After the manipulator approaches the installation position, it slows down and the side blade or end blade is embedded in the installation groove and locked as it rotates. At this time, the bit and the telescopic sleeve slip, and the telescopic sleeve plays a role in pressing the side blade or end blade. Then the bit screws the bolt into the handle to complete the installation;

[0030] 3. Through the setting of the feeding rack, the manipulator can absorb and pick up materials from the second material channel, and can vibrate the second material channel through the manipulator. The deformation of the spring rack allows the first and second material channels to vibrate. During the vibration, the upper bolts will penetrate into the middle hole of the side blade or end blade, and then the internal material will slide to the left to complete the automatic assembly, which is convenient for subsequent direct material picking and assembly, ensuring the automation of the process.

At this time, the tool handle a is released and can be replaced and the rotation angle can be adjusted. When the middle frame 12 swings forward to a horizontal position, the sliding shaft 14 moves forward to push the locking pin 15 into the pin hole a1 of the tool handle a on both sides to lock the position of the tool handle a. The tool handle a can be locked and released by swinging the middle frame 12 ninety degrees, which is convenient for adjustment.

The robot arm 2 installs the side blade a3 and the end blade a4 on the corresponding installation position of the tool handle a through a bolt a31. The feed rack 3 is slidably provided with the side blade a3, the bolt a31 and the end blade a4. The fixture 1 includes a horizontal turntable 11 and a middle frame 12 with a swingable front end. A tool handle seat 122 with a sliding cavity 123 is rotatably installed at the front end of the middle frame 12. A sliding shaft 14 is slidably arranged in the sliding cavity 123. A locking pin 15 that slides left and right is installed at the front end of the sliding shaft 14 in the sliding cavity 123. The locking pin 15 is locked with the pin hole a1 of the tool handle a.

[0047] Specifically, the fixture 1 includes an insert plate 141 that pushes the sliding shaft 14 forward when the middle frame 12 is in a horizontal position. The turntable 11 includes a base 112. The rear end of the middle frame 12 is hingedly installed on the top of the base 112 through a pin shaft. The insert plate 141 is fixed to the front of the top of the base 112. A notch that cooperates with the insert plate 141 is opened at the lower part of the middle frame 12. A middle ring 142 is installed in the middle of the sliding shaft 14, and a permanent magnet spline head 145 is installed at the rear end of the sliding shaft 14. A permanent magnet active ring 143 is installed at the rear of the middle frame 12 at the position of the connecting frame 121.

[0048] Furthermore, a step block 144 is installed at the front end of the sliding shaft 14, and a through hole 152 is opened in the middle of the step block 144 to be slidably assembled and connected with the locking pin 15 relative to the front and rear. A limiting portion 151 is set at the concave position of the locking pin 15 in the sliding cavity 123, and the two ends of the locking pin 15 are set to be hard columnar, and the middle part of the locking pin 15 is set to be spiral.

[0050] During the swinging process of the middle frame 12 from the vertical to the horizontal position, the plug plate 141 is gradually inserted into the notch, and then the sliding shaft 14 is pushed forward through the middle ring 142 to complete the action of pushing the locking pin 15 to both sides. When the middle frame 12 swings to the vertical position, the permanent magnetic active ring 143 will absorb the permanent magnetic spline head 145, so that the sliding shaft 14 moves down. At this time, the servo motor connected to the permanent magnetic active ring 143 can drive the tool handle a to rotate to a corresponding angle, which is convenient for the installation of the next side blade a3. The sliding shaft 14 is connected by spline clamping to ensure that the servo motor and the tool handle a will not be separated. The sliding shaft 14 can play a stable transmission role while playing a locking role. The step block 144 moves forward, and the hard columnar structures at both ends of the locking pin 15 can be inserted into the tool handle a. When the step block 144 moves backward, the spiral structure in the middle of the locking pin 15 The rebound can drive the hard columnar structures at both ends to separate from the tool handle a, and the spiral structure in the middle of the locking pin 15 can slide in the through-hole 152 to ensure that when the step block 144 moves forward and backward, the locking pin 15 will only move horizontally to the left and right to ensure that the position pushed out each time is stable and accurately docked with the pin hole a1 of the tool handle a. The fixed frame 133 can support the lower front end of the horizontal tool handle a, and the swing frame 131 can be driven by the rack 132 and the pinion 135 to rotate and press the upper front end of the tool handle a. When the middle frame 12 is lifted, due to the transmission ratio of the rack 132 and the pinion 135, the swing frame 131 will swing at a faster angular velocity, so that when the middle frame 12 reaches the vertical position, the swing frame 131 will swing to a position disengaged from the limit block a2. Locking and disengagement do not require an external separate driving device, and can be completed only by the swinging of the middle frame 12.
