The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0055] like Figures 1 to 12 The tool positioning and installation tooling suitable for a vertical machine tool shown in the figure comprises: a plurality of tool placement grooves 11 are arranged along the circumferential direction of a tool disc 1, and one side wall of the tool placement groove 11 is arranged inclined toward the adjacent tool placement groove 11; a swing plate 2 is arranged at the inclined side wall position of the tool placement groove 11, and a fan-shaped groove 121 for the swing plate 2 to be embedded is arranged on the top surface of the tool disc 1, and one end of the swing plate 2 close to the center of the tool disc 1 is arranged in the fan-shaped groove 121 through a hinge shaft 2A; a tool positioning assembly 3 comprises two front end limit blocks 31 located at the opening of the tool placement groove 11, and a rear end limit block 32 located at the end position of the tool placement groove 11, and a front end limit block 31 is arranged at the swing end of the swing plate 2;

[0056] Among them, the depth of the fan-shaped groove 121 is equal to the thickness of the swing plate 2, the angle of the fan-shaped groove 121 is greater than or equal to the angle of the two side edges of the swing plate 2, and the tool placement groove 11 is located at the end position. A distance sensor 4 is provided, and a driving component 5 is provided in the tool disc 1 area between two adjacent tool placement grooves 11. The driving end of the driving component 5 is connected to the swing plate 2 so that the swing plate 2 swings around the hinge axis 2A. When the swing plate 2 is swung to be parallel to the relative side walls of the tool placement groove 11, two front end limit blocks 31 and a rear end limit block 32 form a positioning and installation area for accommodating the tool head 01.

[0057] After the swing plate 2 in the present invention is installed into the fan-shaped groove 121, the top surface of the swing plate 2 is flush with the top surface of the cutter disc 1, and the side wall of the knife placing groove 11 on one side of the swing plate 2 is radially inclined outward, and the inclined side wall forms an angle with the other side wall. When the knife needs to be installed, the driving component 5 drives the swing plate 2 to swing toward the side away from the knife placing groove 11 until the swing plate 2 is completely embedded in the fan-shaped groove 121. At this time, the tool handle 00 is sent into the knife placing groove 11 from the side of the cutter disc 1 in the horizontal direction; when the distance sensor 4 senses that the tool has moved to the set distance, the tool stops moving in the horizontal direction, and at the same time, the tool moves downward in the vertical direction until the tool head 01 contacts the front end limit block 31 on the cutter disc 1, and the tool stops moving downward. At this time, the driving component 5 drives The swing plate 2 swings toward the tool side. When the side edge of the swing plate 2 swings to be parallel to the other side wall of the tool placement groove 11, the side wall of the swing plate 2 protrudes from the inclined side wall of the tool placement groove 11. The protruding part of the swing plate 2 contacts the step part of the tool head 01, and forms a support surface for the step surface of the tool head 01 with the other side wall of the tool placement groove 11. The front end limit block 31 on the swing plate 2 and the front end limit block 31 on the tool disc 1 position the front end of the tool head 01, and the rear end limit block 32 located at the end position of the tool placement groove 11 abuts against the rear side wall of the tool head 01, so that the tool head 01 is fixed in the positioning and installation area formed by the two front end limit blocks 31 and the one rear end limit block 32. Finally, the manipulator moves away from the tool in the horizontal direction to realize the positioning and clamping of the tool on the tool disc 1. In the present invention, a swing plate 2 is provided at the inclined side wall of the tool placement groove 11, which can flexibly control the size of the entrance of the tool placement groove 11, provide a larger fault tolerance space for the entry of the tool, thereby reducing the risk of the tool hitting the tool disc 1. During the positioning of the cutter head 01, the part of the swing plate 2 protruding from the inclined side wall can compensate for the support area at the inclined side edge, thereby providing auxiliary support for the cutter head 01 and ensuring the accuracy and stability of the tool positioning.

[0058] When the tool handle 00 of the present invention completely enters the tool placement groove 11, the swing plate 2 swings to be parallel to the side wall opposite to the tool placement groove 11. As the tool moves down to contact the tool disc 1, the rear end limit block 32 contacts the rear side surface of the tool head 01, and the two front end limit blocks 31 contact the front side surface of the tool head 01. However, since there is still a gap between the tool handle 00 and the two side walls in the tool placement groove 11, the centrifugal force generated during the rotation of the tool disc 1 will cause the tool handle 00 to be attached to one of the side walls, resulting in the centering accuracy of the tool in the tool placement groove 11 cannot be guaranteed, which seriously affects the accuracy of the tool removal in the next step. Therefore, in order to further ensure the positioning accuracy of the tool head 01, a limiting step is provided on the side of the front end limit block 31 close to the tool, and the limiting step includes a first abutting surface 311 and a second abutting surface 312 perpendicular to the first abutting surface 311; the first abutting surface 311 abuts against the side wall of the tool head 01, and the second abutting surface 312 abuts against the front wall of the tool head 01. The two front end limit blocks 31 located at the opening of the knife groove 11 have two opposite first abutment surfaces 311 that are equidistant from the adjacent side walls of the knife groove 11. When the tool head 01 is positioned by the limit step, the centering accuracy of the tool handle 00 in the knife groove 11 is further guaranteed, thereby achieving precise positioning of the tool.

[0059] In the preferred embodiment of the present invention, the rear end stopper 32 is arranged at the hinge position of the swing plate 2, including a middle hole 321 for the hinge shaft 2A to pass through, and a first positioning hole 322 arranged radially near one end of the center of the cutter disc 1; the first positioning hole 322 is arranged on one side near the center of the circle, and the rear end stopper 32 is fixed to the cutter disc 1 by bolts passing through the first positioning hole 322; wherein, the end of the rear end stopper 32 away from the first positioning hole 322 is placed above the swing plate 2, and is parallel to the bottom of the fan-shaped groove 121 to form a swing gap, and the swing plate 2 is placed in the swing gap. Through the contact between the cutter head 01 and the rear end stopper 32, the swing angle of the swing plate 2 can be accurately controlled, thereby avoiding the situation where the cutter head 01 cannot be installed.

[0060] In another preferred embodiment, a second positioning hole 323 is provided at one end of the rear end limit block 32 placed above the swing plate 2; a circular hole for accommodating a pin shaft is provided at a position of the swing plate 2 corresponding to the second positioning hole 323, and a positioning pin 33 is provided at the other side wall of the swing plate 2 corresponding to the tool placement groove 11, and the positioning pin 33 abuts against the side wall of the cutter head 01; wherein, an inclined arc surface 324 is provided at the corner of the rear end limit block 32 close to the tool placement groove 11, and when the swing plate 2 swings around the hinge shaft 2A, the pin shaft drives the rear end limit block 32 to rotate synchronously around the hinge shaft 2A, and the inclined arc surface 324 cooperates with the front end limit block 31 on the swing plate 2 to realize the positioning and clamping of the tool. When the tool enters the tool placement groove 11, the front end limit block 31 and the positioning pin 33 located on the same side of the tool placement groove 11 cooperate to achieve accurate positioning of the tool, and the pin shaft is used to make the rear end limit block 32 and the swing plate 2 rotate synchronously. During the rotation process, the inclined arc surface 324 gradually enters the rear wall of the cutter head 01 from one side to evenly apply the thrust to the tool, and cooperates with the front end limit block 31 on the swing plate 2 to clamp the tool, so that the tool is firmly clamped in the positioning and installation area, effectively ensuring the stability of the tool during the clamping process and avoiding the tilting phenomenon caused by uneven force on the tool.

[0061] In the preferred embodiment of the present invention, a fan-shaped support platform 12 is provided between two adjacent tool placement grooves 11, and the fan-shaped support platform 12 includes a fixed surface of the tool disc 1 and a movable surface on the swing plate 2; the drive assembly 5 is provided on the fixed surface to drive the swing plate 2 to swing toward or away from the fixed surface. The fan-shaped support platform 12, as a support point of the swing plate 2, can improve the rigidity of the entire structure and reduce vibration during tool replacement or processing, while the drive assembly 5 is provided on the fixed surface and directly acts on the swing plate 2, and can accurately control the swing angle of the swing plate 2 to achieve accurate positioning of the tool.

[0062] As a preferred embodiment, the driving assembly 5 is arranged at a position close to the outer edge of the fan-shaped supporting platform 12 to provide a larger lever arm, thereby generating a larger torque when the same force is applied, reducing the required driving force. Specifically, the driving assembly 5 includes a cylinder 51 arranged on a fixed surface, and a connecting bracket 52 arranged on a movable surface; the connecting bracket 52 includes a first connecting plate 521 and a second connecting plate 522 arranged vertically, the first connecting plate 521 is fixed on the movable surface, and the second connecting plate 522 is connected to the driving rod of the cylinder 51; wherein, a horizontal long hole 5221 is provided in the second connecting plate 522, and the driving rod of the cylinder 51 passes through the horizontal long hole 5221, and two limit rings 53 are provided at the end of the driving rod of the cylinder 51, and the two limit rings 53 are located on both sides of the second connecting plate 522.

[0063] When the driving rod of the cylinder 51 is extended, the limiting ring 53 located on one side of the cylinder 51 abuts against the second connecting plate 522, driving the swing plate 2 to swing around the hinge shaft 2A, and at the same time the driving rod slides in the horizontal long hole 5221 toward the center of the circle; and when the driving rod of the cylinder 51 is retracted, the limiting ring 53 located on the other side of the second connecting plate 522 applies a pulling force to the connecting bracket 52, so that the swing plate 2 swings into the fan-shaped groove 121, and at this time the driving rod slides in the horizontal long hole 5221 toward the direction away from the center of the circle.

[0064] When the driving rod of the oil cylinder 51 in the present invention makes the swing plate 2 swing, the reciprocating drive of the swing plate 2 relies on the two limit rings 53 to apply force to the second connecting plate 522. As the swing plate 2 is gradually pushed out, the driving rod slides in the horizontal long hole 5221, and the axis of the driving rod forms a moving angle with the second connecting plate 522. After long-term use, the two limit rings 53 will be worn, affecting the control of the swing angle. Preferably, the driving rod of the oil cylinder 51 is located in the middle position of the two limit rings 53 and is sleeved with a universal joint bearing 54; on the two sides of the second connecting plate 522, the track edges of the long holes are located An annular sealing plate 5222 is provided at each of the two annular sealing plates 5222; the inner edges of the two annular sealing plates 5222 extend inwardly to form an annular groove for the outer ring of the universal joint bearing 54 to roll, and the inner ring of the universal joint bearing 54 is fixed on the driving rod; in the initial state, the swing plate 2 is completely embedded in the fan-shaped groove 121, and at this time, the two limit rings 53 are parallel to the second connecting plate 522. When the swing plate 2 swings toward the knife groove 11 to a set angle, the side of the swing plate 2 is parallel to the opposite side of the knife groove 11. At this time, the two limit rings 53 are in contact with the two side surfaces of the second connecting plate 522 respectively to prevent the swing plate 2 from exceeding the set angle.

[0065] The inner ring of the universal joint bearing 54 is fixed on the drive rod, and the outer ring rolls in the annular groove, which can allow the cylinder 51 drive rod to transmit power in multiple directions, so that the swing plate 2 can swing more flexibly. When the limit ring 53 contacts the second connecting plate 522, it provides a clear signal indicating that the swing plate 2 has reached its swing limit position, which helps to accurately control the swing angle of the swing plate 2 and accurately position the tool.

[0066] As a preferred embodiment, a notch is provided on one side of the limiting ring 53, and a locking screw is provided at the notch to make the two opposite sides of the notch close to each other. The limiting ring 53 is detachably arranged on the driving rod of the oil cylinder 51, so as to facilitate the rapid adjustment or replacement of the position of the limiting ring 53, so as to adjust the distance between the two limiting rings 53, and further control the swing angle of the swing plate 2, so as to ensure that the space of the knife placing groove 11 meets the knife placing requirement.

[0067] The present invention also provides a method for using a tool positioning and installation tool suitable for a vertical machine tool, comprising the following steps:

[0068] Rotate the cutter disc 1 to rotate any cutter slot 11 to the cutter change point;

[0069] In the initial state, the swing plate 2 is completely embedded in the fan-shaped groove 121, and the manipulator sends the tool handle 00 from the side of the cutter disc 1 into the cutter placement groove 11 in the horizontal direction. At this time, the manipulator is located below the cutter disc 1;

[0070] As the tool gradually enters, the distance sensor 4 senses that the tool has moved to the set position, and the tool stops moving in the horizontal direction;

[0071] The manipulator drives the tool to move in the vertical direction, descending until the step surface of the cutter head 01 contacts the front end stopper 31 on the cutter disc 1, and the tool stops moving downward;

[0072] Start the driving assembly 5 to drive the swing plate 2 to swing toward the tool side. When the side edge of the swing plate 2 swings to be parallel to the other side wall of the tool placement groove 11, the swing plate 2 and the edge of the other side of the tool placement groove 11 support the step surface of the tool head 01. At this time, the front end limit block 31 on the swing plate 2 and the other front end limit block 31 jointly position the front end of the tool head 01, and the rear end limit block 32 located at the end of the tool placement groove 11 abuts against the side wall of the tool head 01 close to the center of the circle, so that the tool head 01 is fixed in the positioning and installation area.

[0073] Finally, the manipulator moves away from the tool to complete the positioning and clamping of the tool on the cutter disc 1.

[0074] In the present invention, a swing plate 2 is provided at the inclined side wall of the tool placement groove 11, which can flexibly control the size of the entrance of the tool placement groove 11, provide a larger fault tolerance space for the entry of the tool, thereby reducing the risk of the tool hitting the tool disc 1. During the positioning of the cutter head 01, the part of the swing plate 2 protruding from the inclined side wall can compensate for the support area at the inclined side edge, thereby providing auxiliary support for the cutter head 01 and ensuring the accuracy and stability of the tool positioning.
