DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 In this embodiment, an automatic tool changing mechanism for a honing machine includes a base plate 1, a support frame 2 is fixed on the top of the base plate 1, a driving motor 3 is fixed on the top of the base plate 1, the output shaft of the driving motor 3 passes through the interior of the support frame 2, a driving gear 4 is fixed on the output shaft of the driving motor 3, a driven gear 5 is meshed on the left side of the driving gear 4, a rotating rod 6 rotatably connected to the support frame 2 is fixed at the axis of the driven gear 5, a fixed bearing is fixed on the inner top wall of the support frame 2, the interior of the fixed bearing is fixed to the rotating rod 6, and the fixed bearing is provided to make the rotation of the rotating rod 6 more stable.

[0023] In addition, a tool holder 7 is fixed to the top of the rotating rod 6, and a switching assembly 8 is fixed to the top of the base plate 1. The switching assembly 8 is used to change the tool of the honing machine. A tool 9 is fixed inside the tool holder 7. A fixing assembly is provided inside the tool holder 7. The fixing assembly is used to fix the tool 9. The fixing assembly includes a fixing block 10, a fixing plate 11 and a fixing spring 12. The fixed spring 12 can support the fixing block 10, thereby ensuring the stability of the fixation of the tool 9. The fixing block 10 is slidably connected to the tool holder 7, the fixing plate 11 is fixed to the fixing block 10, and the fixing plate 11 is fixed to the fixing spring 12 that fixes the tool holder 7. Inclined surfaces are provided on the upper and lower sides of the fixing block 10. The inclined surfaces are provided so that when the tool 9 is subjected to a large force, the fixed block 10 will be squeezed, thereby making the fixed block 10 away from the tool 9.

[0024] In general, the fixing block 10 can be supported by the fixed spring 12, so that the tool 9 can be fixed inside the tool holder 7. When the tool 9 moves upward or downward with a large force, the inclined surface on the fixing block 10 will be squeezed, so that the fixing block 10 slides toward the inside of the tool holder 7, so that the tool 9 can be disassembled and installed.

[0025] See also Figure 2-3The switching assembly 8 in this embodiment includes a protective box 801, a rotating motor 802, a telescopic rod 803, a limit block 804, two limit plates 805 and a switching frame 806. A card slot is opened inside the switching frame 806, and a rubber pad is fixed inside the card slot. There are two card slots, which can be respectively inserted into the outer surface of the tool holder 7 and the tool 9 on the honing machine. The rubber pad has a certain elasticity, so that the tool 9 inside the card slot can be squeezed, so that the card connection is more stable.

[0026] Furthermore, the protective box 801 is fixed to the base plate 1, the interior of the protective box 801 is fixed to the rotating motor 802, the output shaft of the rotating motor 802 is fixed to the telescopic rod 803 extending to the outside of the protective box 801, the telescopic rod 803 includes an extension rod fixed to the rotating motor 802, the outer surface of the extension rod is threadedly connected to an extension block fixed to the switching frame 806, a threaded strip is fixed to the outer surface of the extension rod, a threaded strip matching the threaded strip is provided inside the extension block, a positioning block is fixed to the outer surface of the extension rod, a positioning groove matching the positioning block is provided inside the protective box 801, the telescopic rod 803 is rotatably connected to the protective box 801, the outer surface of the telescopic rod 803 is fixed to the limit block 804, the limit block 804 is fixed to the telescopic rod 803, and the limit plate 805 is set to limit the turnover of the limit block 804, so that the telescopic rod 803 cannot rotate, so that when the extension rod rotates, the extension block moves due to the extrusion of the thread.

[0027] In addition, the top of the protection box 801 is fixed to the limit plate 805, the top of the telescopic rod 803 is fixed to the switching frame 806, the outer surface of the limit block 804 is covered with a sponge pad, and a ventilation window is opened on the right side of the protection box 801.

[0028] In general, the limit plate 805 limits the rotation of the limit block 804, so that the telescopic rod 803 can only rotate half a circle to complete the swap between the left and right sides of the switching frame 806. Continuing to rotate after the swap will move the non-rotatable extension block and push the switching frame 806 to move up and down.

[0029] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0030] The working principle of the above embodiment is:

[0031] By starting the driving motor 3, the active gear 4 can push the driven gear 5 to rotate, so that the rotating rod 6 drives the tool holder 7 to rotate, and the tool 9 to be replaced is rotated to the left side of the tool holder 7. By starting the rotating motor 802, the telescopic rod 803 can drive the switching frame 806 to rotate, so that the card slot provided in the switching frame 806 is inserted into the outer surface of the tool 9 inside the tool holder 7. At this time, the rotating motor 802 is continued to be started. Because the limit plate 805 limits the turnover of the limit block 804, the telescopic rod 803 can be adjusted in length due to the extrusion of the thread, thereby making the telescopic rod 803 The tool 9 is driven to move downward, so that the tool 9 squeezes the inclined surface of the fixed block 10, so that the fixed block 10 moves to the side away from the tool 9, thereby separating the tool 9 from the tool holder 7. At this time, the rotary motor 802 rotates in the opposite direction, so that the tool 9 rotates to the left, and the limit block 804 contacts the limit plate 805 on the left. Continuing to start the rotary motor 802 can make the telescopic rod 803 extend due to the extrusion of the thread, thereby pushing the switching frame 806 to move upward, completing the installation of the tool 9. The overall structure is simple, which effectively improves the convenience of tool changing, making the overall structure more practical.
