The front end of the upper telescopic rod 44 is fixedly connected with an upper clamping plate 45, and the bottom end of the upper telescopic rod 44 is connected with a pneumatic rod 46. The other end of the pneumatic rod 46 is hinged with a lower telescopic rod 47, and the front end of the lower telescopic rod 47 is fixedly connected with a lower clamping plate 48.

[0048] A control member 49 is arranged on the lower clamping plate 48, and a placing member 410 is arranged on one side of the robotic arm 41.

[0049] In this embodiment, as Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, the control member 49 includes an inner groove 491. The inner groove 491 is opened on the upper clamping plate 45.

[0052] In this embodiment, as Figure 5 shown, the outer diameter of the clamping block 494 matches the inner diameter of the notch, and the plurality of clamping blocks 494 are arranged corresponding to the plurality of notches. When the tool head is located between the upper clamping plate 45 and the lower clamping plate 48, the position of the tool head can be locked through the locking of the clamping blocks 494, facilitating the installation and disassembly of the tool head.

[0053] In this embodiment, as Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the control member 49 further includes a lower arc groove 498 which is formed on the lower clamping plate 48. An inner groove 499 is formed at the end of the lower arc groove 498, and an inner groove 499 with the same structure is formed at the center of the lower arc groove. The inner groove 499 is provided with a trapezoidal structure;

A release groove 4911 is formed at the end of the upper arc groove 4910, and a release groove 4911 with the same structure is formed on the other side of the upper arc groove 4910. The release groove 4911 and the inner groove 499 are arranged in a staggered manner, and the upper arc groove 4910 and the lower arc groove 498 are distributed in a concentric circle structure. Through the staggered arrangement of the upper arc groove 4910 and the lower arc groove 498, when disassembling the tool head, the unlocking of the clamping block 494 in the lower arc groove 498 can be delayed, which is convenient for the movement of the tool head.

[0055] In this embodiment, as Figure 12 and Figure 13 shown, the placing member 410 includes a base 411. The bottom end of the base 411 is fixedly connected to the top end of the machine tool body 1. The top end of the base 411 is rotatably connected to a load-carrying disk 412 through a bearing.

A plurality of annularly arrayed card slots 414 are equidistantly formed at the top end of the cleaning disk 413, and spheres 415 are inserted into the top ends of the plurality of card slots 414, and the top ends of the plurality of spheres 415 are fixedly connected to the bottom end of the cleaning disk 413;

[0056] A trigger post 416 is fixedly connected to the top end of the load-carrying disk 412. A plurality of spiral grooves 417 are annularly arrayed equidistantly on the outer wall of the trigger post 416, and the plurality of spiral grooves 417 are connected through vertical grooves 418, and the vertical grooves 418 are formed on the outer wall of the trigger post 416. A pressure sleeve 419 is sleeved on the outer wall of the trigger post 416, and the top end of the pressure sleeve 419 is fixedly connected to a hydraulic rod 420. The top end of the hydraulic rod 420 is communicated with a hydraulic pump 421, and the hydraulic pump 421 is fixedly connected to the top wall of the machine tool body 1;

[0057] A spring telescopic rod 422 is fixedly connected in the inner wall of the trigger post 416, and the outer diameter of the spring telescopic rod 422 matches the inner diameters of the spiral grooves 417 and the vertical grooves 418. Through the arrangement of the cleaning disk 413, when the upper load-carrying disk 412 rotates to switch the tool head, it triggers the intermittent up and down floating of the load-carrying disk 412 to clean the surface of the placed tool head.

[0058] In this embodiment, as Figure 12 and Figure 13As shown, the spiral groove 417 and the vertical groove 418 are arranged in a Y-shaped structure, and the groove depth of the spiral groove 417 gradually becomes shallower from left to right, and the groove depth of the vertical groove 418 gradually becomes shallower from top to bottom, so that the spring telescopic rod 422 can stably slide in the vertical groove 418 and the spiral groove 417, drive the loading plate 412 to rotate, and switch the tool head.

[0059] In this embodiment, Figure 15 and Figure 16 As shown, the placement member 410 further includes a placement slot 423, which is provided on the loading plate 412, and a plurality of the placement slots 423 are provided in an annular array with equal spacing, a rotating disk 424 is inserted into the inner wall of the placement slot 423, and a shaft 425 is fixedly connected to the bottom end of the rotating disk 424, the cross section of the shaft 425 is a teardrop-shaped structure, and a driving gear 426 is fixedly connected to the bottom end of the shaft 425, and a fixed gear sleeve 427 is meshedly connected to the side wall of the shaft 425, and the fixed gear sleeve 427 is installed on the base 411;

[0060] An extrusion block 428 is fitted and connected to the side wall of the shaft 425, and the extrusion block 428 is slidably connected to the loading plate 412. A pressing block 429 is vertically slidably connected to the inner wall of the loading plate 412, and a push plate 430 is rotatably connected to the side wall of the pressing block 429.

A lower pressure plate 431 is fitted and connected to the top of the pressing block 429, and the side wall of the lower pressure plate 431 is fixedly connected to the side wall of the pressing sleeve 419. By setting the driving gear 426, when the loading plate 412 rotates, the rotating disk 424 can be driven to rotate, so that the material on the rotating disk 424 rotates synchronously, which is convenient for comprehensive cleaning of the cutter head.

[0061] In this embodiment, Figure 15 and Figure 16 As shown, the placement member 410 further includes a left pressure plate 432, the outer wall of the left pressure plate 432 is slidably connected to the inner wall of the rotating disk 424, and a moving groove is provided on the outer wall of the left pressure plate 432, and a telescopic plate 433 is plugged into the moving groove, and the other end of the telescopic plate 433 is fixedly connected to a rotating shaft 434, and the rotating shaft 434 is rotatably connected to the rotating disk 424, and two telescopic plates 433 are symmetrically arranged about the axis of the rotating shaft 434, and a right pressure plate 435 is plugged into the front end of the other telescopic plate 433;

A telescopic spring rod is provided between the bottom end of the tooth plate 437 and the top end of the rotating disk 424.

[0063] The tooth plate 437 is set as an L-shaped structure, and an inclined groove is opened on the outer wall of the tooth plate 437. Through the cooperation of the inclined groove and the protrusion at the bottom end of the lower clamping plate 48, the tooth plate 437 is driven to slide left and right by the left and right rotation of the lower clamping plate 48, so that when the cutter head is released, the rotating disk 424 clamps the cutter head and places the cutter head.

[0064] The use method and advantages of the present invention: The working process of the five-axis linkage machine tool with automatic tool change is as follows:

[0065] like Figures 1 to 16 As shown, first, when it is necessary to replace the tool 3, the staff starts the device and drives the installation cavity 42 to move toward the tool handle 2 through the mechanical arm 41. At this time, the upper clamping plate 45 and the lower clamping plate 48 on the installation cavity 42 will fit with the tool handle 2 and the tool head respectively. At this time, the gas rod 46 is started, and the gas rod 46 drives the upper clamping plate 45 and the lower clamping plate 48 to rotate relative to each other through the upper telescopic rod 44 and the lower telescopic rod 47 on both sides, and the trigger rod 496 on the upper clamping plate 45 moves from the inner groove 499 into the lower arc groove. 498, the trigger rod 496 moves forward, the trigger rod 496 slides on the outer arc groove 495, and pushes the arc frame 492 to rotate. The arc frame 492 rotates, and at this time, the clamping block 494 slides on the outer wall of the upper clamping plate 45, so that the clamping block 494 moves forward. At this time, the clamping block 494 on the upper clamping plate 45 is clamped into the notch on the outer wall of the knife handle 2. At the same time, the lower clamping plate will move out of the release groove 4911, and the clamping block 494 is clamped into the notch on the knife head.

[0066] At this time, the gas rod 46 controls the upper clamping plate 45 and the lower clamping plate 48 to rotate continuously relative to each other, and the cutter head is unscrewed from the knife handle 2. At this time, due to the staggered setting between the release groove 4911 and the inner groove 499, when the upper clamping plate 45 rotates until the cutter head is unscrewed from the knife handle 2, the trigger rod 496 in the upper clamping plate will move to the inner groove 499 at the other end. At this time, the trigger rod 496 moves backward and drives the arc frame 492 to rotate in the opposite direction through the outer arc groove 495, thereby pulling the clamping block 494 out of the notch on the knife handle 2 and releasing the connection between the upper clamping plate 45 and the knife handle 2. However, due to the staggered setting of the release groove 4911 and the inner groove 499, the trigger rod 496 on the lower clamping plate does not enter the release groove 4911 at this time, and the cutter head is stuck between the lower clamping plate 48 and the upper clamping plate 45. At this time, the mechanical arm 41 controls the installation cavity 42 to move downward to pull the cutter head out of the knife handle 2.

[0067] After the cutter head is moved toward the loading plate 412 by the robot arm 41, the cutter head is vertically inserted toward the center of the transmission plate, and the cutter head penetrates the loading plate 412. At the same time, the lower clamping plate 48 is placed on the top of the toothed plate 437. Due to the squeezing force of the lower clamping plate 48, the toothed plate 437 pushes the buckle block 438 downward, and the buckle block 438 no longer fits the inner wall of the loading plate 412. At this time, the toothed plate 437 is unlocked, and the lower clamping plate 48 continues to move until the trigger rod 496 on the lower clamping plate 48 slides into the release groove 4911, and the clamping block 494 on the lower clamping plate 48 is separated from the cutter head, thereby unlocking the cutter head.

[0068] At the same time, when the lower clamping plate 437 contacts the surface of the toothed plate 437, the convex point at the bottom end of the lower clamping plate 48 will be inserted into the oblique groove on the surface of the toothed plate 437, so that when the lower clamping plate 48 rotates to unload the cutter head, the toothed plate 437 can be driven to slide to the left, and the toothed plate 437 moves to the left, driving the toggle gear 436 to rotate clockwise, and the telescopic plate 433 at the front end of the toggle gear 436 will pull the left pressure plate 432 to move to the right, and the telescopic plate 433 at the rear end of the toggle gear 436 can pull the right pressure plate 435 to move to the left, so that the left pressure plate 432 and the right pressure plate 435 slide relative to each other. At the same time, the surfaces of the left pressure plate 432 and the right pressure plate 435 are rubber layers, so that the cutter head can be clamped;

[0069] Then the mechanical arm 41 drives the installation cavity 42 to move upward, and separates the upper clamping plate 45 and the lower clamping plate 48 from the old cutter head. At this time, the hydraulic pump 421 is started, and the hydraulic pump 421 pushes the pressing sleeve 419 to slide downward through the hydraulic rod 420. Since the spiral groove 417 and the vertical groove 418 are arranged in a Y-shaped structure, and the groove depth of the spiral groove 417 gradually becomes shallower from left to right, and the groove depth of the vertical groove 418 gradually becomes shallower from top to bottom, the spring telescopic rod 422 on the pressing sleeve 419 slides downward from the deepest end of the spiral groove 417, pushing the trigger column 416 to drive the loading plate 412 to rotate. At this time, the spring telescopic rod 422 will slide into the vertical groove 418, and the loading plate 412 will move the next new cutter head to the top of the installation cavity 42. At this time, the installation cavity 42 is moved downward, and the lower clamping plate 48 is again separated from the loading plate 412. The toothed plate 437 is connected, and the lower clamping plate 48 is fitted with the side wall of the cutter head. The lower clamping plate 48 and the upper clamping plate 45 are rotated in the opposite direction.
