Description

Technical Field

[0001] This invention belongs to the field of machine tool tool changing, and specifically relates to a tool magazine tool changing and feeding device. Background Technology

[0002] With the continuous improvement of CNC machine tool technology, tool changing speed has become a key factor affecting the overall machining efficiency of machine tools. To improve tool changing efficiency, tool magazines with chuck-type tool holders generally use a tool-changing robot for tool changing. By setting up a tool feeding mechanism in the tool magazine, the tool is pushed to the tool-changing robot, saving tool changing time by preparing the tool in advance. The tool changing action includes: the tool holder descends to the tool holder, the tool holder locks the tool holder, the tool holder is pushed onto the gripper of the tool-changing robot, the tool holder releases the tool holder, and the tool holder is lifted away from the tool holder. In the existing tool feeding mechanism, the tool feeding action needs to be realized by three cylinders. The three cylinders control the raising and lowering of the tool holder, the clamping or releasing of the tool holder, and the movement of the tool holder, respectively. In order to ensure that the action is executed in place, the next cylinder can only be executed after the previous cylinder has completed its action and received a signal. It is difficult to guarantee the continuity of the action, which increases the preparation time and is not conducive to improving tool changing efficiency. Furthermore, each of the three cylinders needs to be equipped with a magnetic switch to detect whether the cylinder is in place, which involves many electrical components and has many potential failure points.

[0031] The forward and backward moving device 7 includes a mounting plate 71 and a horizontal guide rail 72. The horizontal guide rail 72 is fixed to the lower end of the mounting plate 71 and is slidably connected to the horizontal slide block 73. A second slide groove 711 is provided on the left side of the mounting plate 71. The second roller 56 is installed in the second slide groove 711 and can roll along the second slide groove 711, thereby converting the swing of the second swing arm 54 into the horizontal linear movement of the mounting plate 71.

[0032] The lifting device 8 includes a lifting guide rail 81, a lifting plate 82, and a horizontal guide wheel 83. The lifting guide rail is fixed on the mounting plate 71, the lifting plate 82 is slidably mounted on the lifting guide rail 81, and the horizontal guide wheel 83 is mounted on the left side of the lifting plate 82. In order to enable the lifting plate 82 to move up and down along the lifting guide rail 81 under the drive of the up and down sliding device 6, and to move back and forth together with the mounting plate 71, a horizontal guide groove 611 is provided on the right side of the sliding plate 61. The horizontal guide groove 611 is arranged in the front and back direction, and the horizontal guide wheel 83 is installed in the horizontal guide groove 611 and can move back and forth along the horizontal guide groove 611.

[0033] Combination Figure 2 and Figure 6 As shown, the tool holder 9 includes a sleeve body 91, a steel ball seat 92, a locking rod 93, a locking limit sleeve 94, steel balls 95, a locking spring 96, and a lifting rod 97. The steel ball seat 92 is fixed inside the sleeve body 91. Steel ball holes are evenly distributed along the circumference of the steel ball seat 92, and a steel ball 95 is installed in each steel ball hole. The locking limit sleeve 94 and the locking rod 93 are both installed inside the steel ball seat 92 and are distributed vertically along the steel ball seat 92. A locking spring 96 is installed between the locking limit sleeve 94 and the locking rod 93. Under the action of the locking spring 96, the locking rod 93 moves downward to push the steel ball 95 out of the steel ball hole, thereby locking the tool holder. A lifting rod 97 is fixed to the upper end of the locking rod 93. The lifting rod 97 is provided with an annular groove 971, and the lifting plate 82 is provided with a U-shaped slot 821. The U-shaped slot 821 is inserted into the annular groove 971 to connect the lifting rod 97 and the lifting plate 82 together. As the lifting plate 82 moves upward, the lifting rod 97 can pull the locking rod 93 upward, thereby releasing the tool holder.

[0034] The sleeve 91 is disposed in the inner hole of the tool holder 10, which is fixed to the mounting plate 71. A first guide rod 101 and a second guide rod 102 are fixed on the tool holder 10. The sleeve 91 has two guide holes, which respectively mate with the first guide rod 101 and the second guide rod 102. A first compression spring 103 and a second compression spring 104 are respectively disposed on the first guide rod 101 and the second guide rod 102. The first compression spring 103 compresses between the first guide rod 101 and the sleeve 91, and the second compression spring 104 compresses between the second guide rod 102 and the sleeve 91. The initial combined compression force of the first compression spring 103 and the second compression spring 104 is greater than the compression force of the locking spring 96 when the lifting rod 97 is raised to the tool release position. This effectively ensures that when the lifting rod 97 is raised, the locking spring 96 compresses first, releasing the tool handle, and then pulls the entire tool holder 9 upward, thus actively releasing the tool. Corresponding to the first guide rod 101, the lifting plate 82 is provided with a clearance hole 822 to prevent the lifting plate 82 from interfering with the first guide rod 101 when it moves up and down.

[0035] During tool changing, the motor 31 rotates, driving the worm gear 32 to rotate. The worm gear 32, through the worm wheel gear transmission on the double-sided cam 2, drives the double-sided cam 2 to rotate. The left cam groove 25 on the double-sided cam 2 drives the first rocker arm 42 to swing upward around the first support bearing 45 via the first needle roller bearing 41. The first rocker arm 42 drives the first swing arm 44 to swing downward around the first support bearing 45, thereby pushing the slide plate 61 downward through the first slide groove 441 and the first roller 62. The slide plate 61 drives the lifting plate 82 to move downward, and under the compression force of the first compression spring 103 and the second compression spring 104, pushes the sleeve 91 downward onto the tool holder. Then, under the compression force of the locking spring 96, the locking rod 93 moves downward, pushing the steel ball 95 out of the steel ball hole, thereby locking the tool holder.

[0036] Next, the right cam groove 26 on the double-sided cam 2 drives the second rocker arm 52 to swing backward around the second support bearing 55 via the second needle roller bearing 51. The second rocker arm 52 drives the second swing arm 54 to swing forward around the second support bearing 55, which in turn pushes the mounting plate 71 forward via the second roller 56 and the second slide groove 711. The tool holder 9 drives the tool handle to move forward with the mounting plate 71 and moves the tool handle onto the robotic arm gripper.

[0037] Then, the left cam groove 25 on the double-sided cam 2 drives the first rocker arm 42 to swing downward around the first support bearing 45 via the first needle roller bearing 41. The first rocker arm 42 drives the first swing arm 44 to swing upward around the first support bearing 45, and then pushes the slide plate 61 to move upward through the first slide groove 441 and the first roller 62. This sequentially drives the lifting plate 82, the lifting rod 97 and the locking rod 93 to move upward and loosen the tool handle. The lifting rod 97 continues to move upward, and through the locking rod 93 and the locking spring 96, it drives the sleeve 91 to move upward and disengage from the tool handle.

[0038] The robotic gripper rotates 180 degrees. The left cam groove 25 on the double-sided cam 2 drives the first rocker arm 42 to swing upward around the first support bearing 45 via the first needle roller bearing 41. The first rocker arm 42 drives the first swing arm 44 to swing downward around the first support bearing 45, which in turn pushes the slide plate 61 downward through the first slide groove 441 and the first roller 62. The slide plate 61 drives the lifting plate 82 to move downward, and under the compression force of the first compression spring 103 and the second compression spring 104, pushes the sleeve 91 downward to the tool handle on the other side of the robotic gripper. Under the compression force of the locking spring 96, the locking rod 93 moves downward, pushing the steel ball 95 out of the steel ball hole and locking the tool handle.

[0039] The right cam groove 26 on the double-sided cam 2 drives the second rocker arm 52 to swing forward around the second support bearing 55 via the second needle roller bearing 51. The second rocker arm 52 drives the second swing arm 54 to swing backward around the second support bearing 55, which in turn pulls the mounting plate 71 backward via the second roller 56 and the second slide groove 711. The tool holder 9 drives the tool holder to move backward with the mounting plate 71 and moves the tool holder onto the tool magazine chuck.

[0040] The left cam groove 25 on the double-sided cam 2 drives the first rocker arm 42 to swing downward around the first support bearing 45 via the first needle roller bearing 41. The first rocker arm 42 drives the first swing arm 44 to swing upward around the first support bearing 45, which in turn pushes the slide plate 61 to move upward through the first slide groove 441 and the first roller 62. This drives the lifting plate 82, the lifting rod 97 and the locking rod 93 to move upward in sequence and release the tool handle. The lifting rod 97 continues to move upward, and the sleeve 91 moves upward and disengages from the tool handle through the locking rod 93 and the locking spring 96. The motor 31 stops rotating, thus completing one tool change action.

[0041] Although the present invention has been described in detail above, it is not limited thereto, and those skilled in the art can make various modifications based on the principles of the present invention. Therefore, all modifications made in accordance with the principles of the present invention should be understood to fall within the protection scope of the present invention.
