DETAILED DESCRIPTION

[0026] In order to make the technical problem, technical scheme and beneficial effect solved by the utility model more clearly, the following is further explained to the utility model by combining with the drawings and examples.

[0027] As Figures 1-6As shown, this utility model provides a hollow indexing disc hopper for cutting tools and workpieces, including a frame 1, a motor 2, a hollow reducer 3, an indexing disc 4, a fixed shaft 5, an extension frame 6, and a pusher positioning and detection device 7. The motor 2 drives and connects to the hollow reducer 3. The hollow reducer 3 is fixed on the frame 1 and its output end face is fixedly connected to the indexing disc 4. A first through hole 8 is opened in the center of the indexing disc 4. The fixed shaft 5 is fixed on the hollow reducer 3 and its top passes through the first through hole 8. The extension frame 6 is fixed on the upper part of the fixed shaft 5. The pusher positioning and detection device 7 is fixed on the extension frame 6 and is used to detect and push the workpiece 21.

[0028] The output end of motor 2 is connected to the input end of hollow reducer 3. Motor 2 transmits power to hollow reducer 3, and then to indexing plate 4, causing indexing plate 4 to rotate relative to frame 1. Hollow reducer 3 is fixed on frame 1, and fixed shaft 5 is fixed on hollow reducer 3. Therefore, fixed shaft 5 is fixed relative to frame 1. Fixed shaft 5 passes through first through hole 8 through indexing plate 4 without affecting the rotation of indexing plate 4, thus ensuring that the position of push knife positioning detection device 7 on extension frame 6 is fixed.

[0029] The hollow reducer 3 has a second through hole 9 in the vertical direction. The lower part of the fixed shaft 5 passes through the second through hole 9 and the bottom end is fixed to the bottom of the hollow reducer 3 by the shaft fixing member 10. The output end face of the hollow reducer 3 avoids the first through hole 8 to make room for the installation of the fixed shaft 5. The fixed shaft 5 is fixed on the shaft fixing member 10, and the shaft fixing member 10 is fixed to the bottom of the hollow reducer 3. The position of the fixed shaft 5 is defined by the shaft fixing member 10, thus fixing the fixed shaft 5 to the hollow reducer 3. The extension frame 6 and the pusher positioning detection device 7 are located in the middle area of ​​the indexing plate 4. Compared with placing the pusher positioning detection device 7 on the periphery of the indexing plate 4, this utility model makes full use of the middle area of ​​the indexing plate 4, saves space, and leaves more operating space for the articulated robot 20.

[0030] A connecting plate 11 is fixed to the output end face of the hollow reducer 3. The top of the connecting plate 11 is fixed to the bottom of the indexing plate 4, and the fixed shaft 5 passes through the connecting plate 11. The hollow reducer 3 and the indexing plate 4 are fixedly connected by the connecting plate 11. The fixed shaft 5 passes through the connecting plate 11, and the rotation of the connecting plate 11 does not affect the fixed position of the fixed shaft 5.

[0031] The upper part of the fixed shaft 5 is provided with an adjusting member 12 for fixing the extension frame 6. The adjusting member 12 is detachable from the fixed shaft 5. The extension frame 6 is fixed on the adjusting member 12. By adjusting the position of the adjusting member 12 on the fixed shaft 5, the height of the extension frame 6 and the pusher positioning detection device 7 is adjusted so that they can accurately sense the workpiece 21 and push the workpiece 21.

[0032] The pusher positioning and detection device 7 includes a workpiece sensor 71, a telescopic cylinder 72, and a pusher plate 73. The workpiece sensor 71 and the telescopic cylinder 72 are fixed on the extension frame 6. The workpiece sensor 71 is used to detect whether there is a workpiece 21 on the work station. The pusher plate 73 is fixed to the telescopic end of the telescopic cylinder 72 and is used to push the workpiece 21 on the work station.

[0033] A connecting flange 13 is fixed on the hollow reducer 3, and the hollow reducer 3 is fixed on the frame 1 through the connecting flange 13.

[0034] The indexing plate 4 has several clearance holes 14 along its circumference. A positioning frame 15 is provided on the outer side of the indexing plate 4. A lifting assembly 16 is provided on the positioning frame 15. A positioning shaft 17 is fixed to the top of the lifting assembly 16. The positioning shaft 17 can pass through the clearance holes 14 when moving upward. The lifting assembly 16 can be moved up and down using a cylinder, lead screw, or other structure. In one embodiment, the lifting assembly 16 includes a lifting cylinder, and the positioning shaft 17 is fixed to the top of the lifting cylinder.

[0035] The positioning shaft bracket 17 has a positioning groove 18. When the lifting component 16 moves upward, the positioning shaft bracket 17 moves upward and lifts the workpiece 21 on the tool holder 19. The workpiece 21 is confined in the positioning groove 18, which increases stability.

[0036] The indexing plate 4 is provided with several tool holders 19 along its circumference. The tool holders 19 are used to place the workpiece 21, and the clearance hole 14 is provided under the tool holder 19.

[0037] Working principle: The control device controls the motor 2 to work intermittently. The motor 2 transmits power to the hollow reducer 3. The hollow reducer 3 drives the connecting plate 11 and the indexing plate 4 to rotate intermittently. The workpiece 21 (i.e., knife and scissors) is placed on the tool holder 19 of the indexing plate 4. Each time the indexing plate 4 rotates to a tool holder 19, the lifting component 16 drives the positioning shaft 17 to move upward. The positioning shaft 17 passes through the clearance hole 14 and lifts the workpiece 21 to the loading and unloading station. After the workpiece sensor 71 senses the workpiece 21 at the station, the telescopic cylinder 72 drives the push plate 73 to extend horizontally forward. The push plate 73 pushes the tip of the blade of the workpiece 21. At this time, the articulated robot 20 takes away the workpiece 21.

[0038] This invention fixes the output end face of the hollow reducer 3 to the indexing plate 4 to achieve the rotation of the indexing plate 4; fixes the fixed shaft 5 on the hollow reducer 3, the fixed shaft 5 passes through the indexing plate 4, and fixes the push-tool positioning detection device 7, so that the push-tool positioning detection device 7 is fixed in the middle area of ​​the indexing plate 4. Compared with the prior art, it not only makes full use of the space in the middle area of ​​the indexing plate 4, but also avoids occupying the space on the outside of the indexing plate 4, which can leave more operating space for the articulated robot 20. In addition, since the push-tool positioning detection device 7 is located inside the tool holder 19, it can push the tip of the workpiece 21. Compared with pushing the tool holder end, pushing the tip of the tool can make the positioning more accurate and the precision higher.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
