Abstract
Description
Technical Field
[0001] This utility model relates to the field of sorting machine technology, and in particular to an automatic sorting machine for tool hardness. Background Technology
[0002] CNC cutting tools are cutting tools used in conjunction with CNC machine tools. They are key tools used in machining to cut workpieces. The accuracy and performance of CNC cutting tools directly affect the dimensional accuracy, surface quality, and machining efficiency of machined parts. In order to ensure the stability of machining quality and reduce machining defects and equipment wear caused by tool hardness issues, sorting machines are usually used to specifically test and sort tool hardness, thereby ensuring that the hardness of tools entering the production process meets the standards.
[0003] In the existing technology, when it is necessary to adjust the worktable to a specific angle or to perform equipment maintenance, it is necessary to use external tools to disassemble the relevant parts, which makes the operation cumbersome and time-consuming, and easily affects the adjustment efficiency and maintenance convenience of the equipment. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an automatic tool hardness sorting machine, which aims to improve the problem that the existing technology cannot quickly adjust the worktable to a specific angle, thus affecting the use of the equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic tool hardness sorting machine, comprising:
[0006] A base, with a support rod rotatably connected to its inner wall, a connecting seat engaged at the top of the support rod, a servo motor fixedly connected to the top of the connecting seat, a worm gear fixedly installed at the output end of the servo motor, a first connecting member fixedly connected to the surface of the worm gear, a pull rod fixedly connected to the inner wall of the first connecting member, a worm wheel meshing with the surface of the worm gear, a rotating sleeve fixedly connected to the top of the worm wheel, and a multi-station mechanism installed at the top of the rotating sleeve;
[0007] A support base is fitted to the bottom surface of the worm gear, and a rotating shaft is fixedly connected to the surface of the support base.
[0008] The above technical solution, by pulling down to disengage the worm and worm wheel and rotating the worktable independently, avoids the problem of slow adjustment of the initial angle of the worktable and reduced work efficiency caused by the low-speed transmission of the worm and worm wheel when changing tools of different sizes.
[0009] Preferably, the sorting machine further includes a cylinder, which is fixedly connected to the support base, and a piston is slidably connected to the inner wall of the cylinder, with a movable column rotatably connected to the top of the piston;
[0010] The above technical solution involves adding a cylinder to control the lifting and lowering of the worktable. When the multi-directional mechanical gripper places the tool, the lifting worktable works in conjunction with the multi-directional mechanical gripper, reducing the impact of positional deviation between the tool and the mechanical gripper.
[0011] Preferably, the multi-station mechanism includes a worktable, which is fixedly connected to a rotating sleeve. The worktable surface is evenly provided with connecting grooves, and fixing clamps are fixedly connected to both sides of the inner wall of the connecting grooves. The fixing clamps are used to fix the cutting tool.
[0012] The above technical solution achieves orderly switching between different stations of the sorting machine by fixing the worktable to the rotating sleeve.
[0013] Preferably, a multi-directional mechanical claw is fixedly connected to the top of the base, and the multi-directional mechanical claw is used to clamp and place the tool.
[0014] Preferably, a hardness tester is fixedly connected to the top of the base, and the hardness tester is used to test the hardness of the cutting tool.
[0015] Preferably, a second connector is fixedly connected to the inner surface of the connector, the second connector is rotatably connected to the rotating shaft and the worm gear respectively, and the second connector is fixedly connected to the pull rod.
[0016] Preferably, the first connecting member is rotatably connected to both the rotating shaft and the worm gear.
[0017] Preferably, the top surface of the piston is in contact with the bottom surface of the rotating sleeve, and the piston is slidably connected to the inner wall of the support seat.
[0018] This utility model has the following beneficial effects:
[0019] 1. In this utility model, the meshing state of the worm and worm wheel can be disengaged by moving the pull rod downward, which facilitates the rapid rotation of the worktable to a specific angle. At the same time, it can quickly clean and inspect the tooth surface condition of the worm and worm wheel, and perform maintenance on the sorting machine.
[0020] 2. In this utility model, the tool to be tested is moved to the bottom detection position of the hardness tester probe by rotating the worktable, and the tool is moved to the sorting position by rotating the worktable, thereby realizing the rapid switching of the work position and shortening the tool testing cycle.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1:
[0029] Reference Figures 1-3 This utility model provides an embodiment of an automatic tool hardness sorting machine, comprising a base 1, a support rod 3 rotatably connected to the inner wall of the base 1, a connecting seat 5 engaged at the top of the support rod 3, a servo motor 6 fixedly connected to the top of the connecting seat 5, a worm gear 13 fixedly disposed at the output end of the servo motor 6, a first connecting member 11 fixedly connected to the surface of the worm gear 13, a pull rod 12 fixedly connected to the inner wall of the first connecting member 11, a worm wheel 14 meshing with the surface of the worm gear 13, a rotating sleeve 15 fixedly connected to the top of the worm wheel 14, a multi-station mechanism disposed at the top of the rotating sleeve 15; a support seat 10, the support seat 10 being in contact with the bottom surface of the worm wheel 14, and a rotating shaft 20 fixedly connected to the surface of the support seat 10.
[0030] Specifically, the worm gear 13 and worm wheel 14 mesh to achieve self-locking, which can prevent angular deviation during the operation of the multi-station mechanism and ensure the stability of the sorting machine. The servo motor 6 controls the rotation of the worm gear 13 and worm wheel 14, which enables more accurate adjustment of the angle of the rotating sleeve 15, thereby improving the rotation accuracy of the worktable 7. The support rod 3 connects the connecting seat 5 and the base 1, which can further support the servo motor 6.
[0031] Reference Figures 1-2 The multi-station mechanism includes a worktable 7, which is fixedly connected to a rotating sleeve 15. The surface of the worktable 7 is evenly provided with connecting grooves 8, and both sides of the inner wall of the connecting grooves 8 are fixedly connected with fixing clips 9, which are used to fix the cutting tools.
[0032] Specifically, the connecting grooves 8 evenly distributed on the surface of the worktable 7 allow multiple tools to be placed on the worktable 7 simultaneously. When one tool is being tested at the hardness tester 2, the other tools can be in different states of being tested or being sorted, thereby shortening the testing cycle of a single tool and improving the overall testing and sorting efficiency.
[0033] Reference Figure 2 The top of the base 1 is fixedly connected to a multi-directional mechanical claw 4, which is used to clamp and place the cutting tool.
[0034] Specifically, the multi-directional mechanical gripper 4 has multi-angle rotation capability, which can adapt to the tool clamping and placement requirements of different work positions and different postures. The multi-directional mechanical gripper 4 can grab the tool from the tool storage area, put the tool into the connecting groove 8, and fix the tool with the fixing clamp 9. After the tool has been tested by the hardness tester 2, the multi-directional mechanical gripper 4 moves the tool to the corresponding sorting area to realize the automated sorting of tools.
[0035] Reference Figure 1 A hardness tester 2 is fixedly connected to the top of the base 1. The hardness tester 2 is used to test the hardness of the tool.
[0036] Specifically, when the tool to be tested is securely fixed in the connecting groove 8 of the worktable 7 by the fixing clamp 9, and rotates with the worktable 7 to the testing area of the hardness tester 2, the testing probe of the hardness tester 2 contacts the tool surface downward to measure the hardness.
[0037] Reference Figure 3 A second connector 19 is fixedly connected to the inner surface of the connector 5. The second connector 19 is rotatably connected to the rotating shaft 20 and the worm gear 13 respectively. The second connector 19 is fixedly connected to the pull rod 12.
[0038] Specifically, when the worm 13 rotates under the drive of the servo motor 6, it is rotatably connected to the worm 13 through the second connecting piece 19, which ensures that the worm 13 can mesh with the worm wheel 14 for transmission. At the same time, the two connecting pieces can provide support for the worm 13, preventing the worm 13 from axially shifting and affecting the operation of the sorting machine.
[0039] Reference Figures 1-3 The first connecting piece 11 is rotatably connected to the rotating shaft 20 and the worm gear 13 respectively;
[0040] Specifically, when the pull rod 12 is pulled, the first connecting piece 11 and the second connecting piece 19 can rotate around the rotating shaft 20. Since the connecting pieces are rotatably connected to the worm 13, the connecting pieces can drive the worm 13 to move without affecting the rotation function of the worm 13 itself, thereby realizing the separation of the worm 13 from the worm wheel 14.
[0041] Example 2:
[0042] Reference Figure 4 The sorting machine also includes a cylinder 16, which is fixedly connected to the support base 10. A piston 17 is slidably connected to the inner wall of the cylinder 16, and a movable column 18 is rotatably connected to the top of the piston 17.
[0043] Specifically, the movable column 18 is connected to the rotating sleeve 15 via a cross spline, so that the movable column 18 can lift the worktable 7 and rotate together with the rotating sleeve 15. The cylinder 16 can control the lifting and lowering of the top worktable 7, so that the worktable 7 can be adjusted according to the height of different tools and the position of the hardness tester 2 detection probe, ensuring that the tool is in the optimal height position during testing, thus improving the accuracy of hardness testing.
[0044] Reference Figure 4 The top surface of piston 17 is in contact with the bottom surface of rotating sleeve 15, and piston 17 is slidably connected to the inner wall of support seat 10.
[0045] Specifically, when the piston 17 moves upward under the drive of the cylinder 16, its top end can tightly press against the bottom of the rotating sleeve 15, thereby limiting the extension distance of the piston 17 through the rotating sleeve 15, preventing the worktable 7 from rising too high due to the piston 17 extending too far, and ensuring the safe operation of the sorting machine.
[0046] Working principle: When the sorting machine is running, the tool to be tested is placed on the top of the worktable 7 by the multi-directional mechanical claw 4 and fixed by the fixing clamp 9. The worktable 7 is rotated by the servo motor 6, so that the tool to be tested is moved to the bottom detection position of the hardness tester 2 probe. After detection, the worktable 7 is rotated again by the servo motor 6 to the sorting position. The multi-directional mechanical claw 4 sorts the tested tool, so that the sorting machine can switch positions by rotation, reducing the translation and handling of the tool.
[0047] The servo motor 6 can control the worktable 7 to rotate at a small and accurate angle through the transmission of worm gear 13 and worm wheel 14. By pulling down the pull rod 12, the first connecting piece 11 and the second connecting piece 19 rotate around the rotating shaft 20, thereby disengaging the worm gear 13 and worm wheel 14. When inspecting tools of different diameters and lengths, the worktable 7 needs to be rotated to a specific initial angle. After disengaging the worm gear 13 and worm wheel 14, the worktable 7 can be manually and quickly rotated to the target angle. This also facilitates cleaning and inspection of the tooth surface condition of the worm gear 13 and worm wheel 14, and maintenance of the sorting machine.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
