Description

Technical Field

[0001] The utility model relates to the field of mechanical manufacturing, in particular to a tool adjustment device. Background Art

[0002] In the machining industry, holes are the most common feature. Hole machining involves drills, reamers, fine boring cutters and other related tools. Among them, fine boring cutters are the most useful. Generally, fine boring cutters are used to ensure the dimensional accuracy and positional accuracy of the holes. The diameter of the hole is determined by the diameter of the fine boring cutter, which is bound to result in a variety of sizes of fine boring cutters. On the other hand, it is also limited by the mechanical structure of the boring cutter. At present, all boring cutter diameters on the market are manually adjusted using hexagonal bars, which increases tool management and personnel costs, especially in the discrete manufacturing industry. This situation is even worse, and it is also a key factor restricting machining automation.

[0003] Considering the requirements of automation and intelligent manufacturing, if the manual adjustment of the fine boring tool can be changed to automatic adjustment, it will be one step closer to the big scene of intelligent manufacturing; limited by the cost and application of tools, all tool manufacturers on the market currently do not have tool products that can automatically adjust boring tools. Machine tools do not have related functions; therefore, there is currently no solution for automatic adjustment of boring tools on the market. On the other hand, aperture tolerance is a common phenomenon, most of which is caused by the wear of the blade of the fine boring tool or the tool letting the tool, which requires manual adjustment of the size of the fine boring tool to solve this problem, which leads to a low degree of automation, let alone intelligent manufacturing. With the development of visual technology, the technology of shooting and positioning through visual cameras has become increasingly mature and has been applied in the manufacturing field. Therefore, the use of existing visual technology to adjust boring tools provides a research direction for the intelligent automatic adjustment of boring tools. Utility Model Content

The quick-change positioning mechanism includes a quick-change positioning disk 2, the wrench placement seat 7 is installed on the quick-change positioning disk 2, the adjustment wrench 8 is placed on the wrench placement seat 7, the manipulator 3 is installed on the quick-change positioning disk 2, the clamping mechanism 5 and the knob drive mechanism 4 are both installed on the manipulator 3, the clamping mechanism 5 can clamp the adjustment wrench 8, the knob drive mechanism 4 is connected to the clamping mechanism 5, and can drive the clamping mechanism 5 to rotate; the visual recognition mechanism 6 includes a visual camera fixed on the manipulator 3, the visual recognition mechanism 6 is communicatively connected to the control mechanism 9, and the control mechanism 9 is respectively controlled and connected to the manipulator 3, the knob drive mechanism 4 and the clamping mechanism 5; the energy storage mechanism 10 is connected to the manipulator 3 to provide electrical energy for the movement of the manipulator 3.

[0038] The basic working principle of the tool adjustment device of the present invention is: the tool adjustment device can be used to adjust the boring tool 12 or similar tools. The quick-change positioning mechanism is used for rapid installation and removal on the machine tool, and serves as the installation basis for other mechanisms of the tool adjustment device. When in use, the machine tool finds the fine boring tool 12 that needs to be adjusted; the tool adjustment device is moved to the machine tool and installed on the machine tool table 11 through the quick-change positioning mechanism, see Figure 1; The machine tool spindle grabs the fine boring tool 12 that needs to be adjusted, opens it to the specified safe position and locks it, and the adjusting wrench 8 selects a suitable type of wrench according to the specific situation of the fine boring tool 12. Specifically, in this embodiment, the fine boring tool 12 has a locking screw and an adjusting screw. When the adjusting screw is rotated, the diameter of the fine boring tool 12 can be adjusted. The locking screw is used to lock the diameter of the fine boring tool 12 or unlock it. The locking screw and the adjusting screw are both hexagon socket screws, and the adjusting wrench 8 selects a hexagon socket wrench accordingly. Then, the movement of the manipulator 3 is controlled by the control mechanism 9 to drive the clamping mechanism 5 to move to the wrench placement seat 7. The control mechanism 9 can control the clamping action and the loosening action of the clamping mechanism 5. The clamping mechanism 5 grabs the corresponding adjusting wrench 8 and clamps and fixes the adjusting wrench 8; then the manipulator 3 is opened to the side of the boring tool 12, and the visual recognition mechanism 6 is used for visual recognition and positioning. The visual camera is used to shoot, identify and locate to determine the position and angle of the locking screw and the adjusting screw, and then transmit the positioning information to the control mechanism 9, wherein the visual camera is preferably arranged at the attachment of the clamping mechanism 5. When the adjusting wrench 8 is close to the boring tool 12, the visual camera can better realize visual shooting. The control mechanism 9 includes a controller, which is used to control the movement of the manipulator 3 according to the positioning information of the visual recognition mechanism 6, drive the adjusting wrench 8 to move to the corresponding position, and adjust the position and angle of the adjusting wrench 8 so that it is aligned with the locking screw of the fine boring tool 12 and the angle is consistent, and the adjusting wrench 8 is inserted into the locking screw, and then the twisting drive mechanism 4 drives the adjusting wrench 8 to rotate and loosen the locking screw. At this time, the diameter of the fine boring tool 12 is in an adjustable state; then the manipulator 3 moves to the back of the boring tool 12, and also determines the position and angle of the adjusting screw through visual recognition positioning. The manipulator 3 adjusts the position and angle of the adjusting wrench 8 so that it is aligned with the adjusting screw and the angle is consistent, inserts the adjusting wrench 8 into the adjusting screw, and then controls the twisting drive mechanism 4 to drive the adjusting wrench 8 to rotate a certain angle, drives the adjusting screw to rotate, and adjusts the diameter of the fine boring tool 12. The rotation angle is the difference between the target diameter and the existing diameter converted into the angle of the adjusting screw; after the adjustment is completed, the locking screw can be tightened again in the same way as the above-mentioned loosening of the locking screw. After the boring tool 12 is adjusted, the tool adjustment device is removed from the machine tool through the quick-change positioning plate 2.

[0039] In the present utility model, the visual recognition mechanism 6 is used to identify and locate objects by shooting, and specifically, existing mature products can be used. In terms of hardware structure, the visual recognition mechanism 6 generally includes structures such as a visual camera and a data processor. The visual camera shoots and transmits image data to the data processor for processing. The data processor is used for storage and data calculation and processing, and a corresponding calculation processing program can be built in. Among them, the visual recognition positioning method required by the visual recognition mechanism 6, and the method of driving the manipulator to move to a specified position after visual recognition and positioning, are all existing mature methods, such as: "Visual recognition and positioning technology of components based on deep learning" (Lei Wentong, Gu Jinan, etc., School of Mechanical Engineering, Jiangsu University, Zhenjiang 2012013), "Research on autonomous grasping of workpieces by manipulators based on machine vision" (Sun Wanlin's master's thesis, Tarim University), patent CN 201911310686.3 "Manipulator grasping method, device, computer-readable storage medium and robot".

[0040] In this embodiment, see Figure 1 As a preferred design, in this embodiment, it also includes a quick-change positioning base 1 for fixing on a machine tool, a first positioning connection structure is provided on the quick-change positioning base 1, a second positioning connection structure matched with the first positioning connection structure is provided on the quick-change positioning disk 2, and the quick-change positioning disk 2 is fixed on the quick-change positioning base 1 through the matching connection of the first positioning connection structure and the second positioning connection structure, and the manipulator 3, the rotary drive mechanism 4, the clamping mechanism 5, the wrench placement seat 7, the adjustment wrench 8, the visual recognition mechanism 6, the energy storage mechanism 10 and the control mechanism 9 and other structures are all arranged on the quick-change positioning disk 2, and can be carried as a whole with the quick-change positioning disk 2. The first positioning connection structure and the second positioning connection structure can adopt existing structures that can achieve fast and stable connection, such as the positioning block and the positioning groove can be matched and snapped together. During the machining process, the quick-change positioning base 1 can be fixed on the machine table 11 without affecting the proper position of machining. Whenever the boring tool 12 needs to be adjusted, the quick-change positioning plate 2 carrying the manipulator 3, the rotary drive mechanism 4, the clamping mechanism 5, the wrench placement seat 7, the adjustment wrench 8, the visual recognition mechanism 6, the energy storage mechanism 10 and the control mechanism 9 only needs to be quickly positioned and installed on the quick-change positioning base 1. After the tool is adjusted, the quick-change positioning plate 2 is detached from the quick-change positioning base 1. In this way, it can be ensured that each time the tool is adjusted, the tool adjustment device is in the same position of the machine tool and does not occupy the machine tool resources.

[0041] In this embodiment, see Figure 1As a preferred design, the upper end of the quick-change positioning disk 2 is provided with a mounting surface, and the lower end is used to connect with the quick-change positioning base 1. A plurality of positioning holes 201 are provided on the mounting surface. The positioning holes 201 are preferably arranged in an array and cover the entire mounting surface. The manipulator 3, the wrench placement seat 7, the energy storage mechanism 10 and the control mechanism 9 are all fixedly connected in the positioning holes 201 by bolts, so that the relative positions of the manipulator 3 and the wrench placement seat 7 on the quick-change positioning disk 2 can be conveniently adjusted as needed, so as to facilitate the taking and adjusting of the wrench 8. A transport interface 202 is also provided on the side of the quick-change positioning disk 2, and the transport interface 202 is used to connect with a transport robot, so as to facilitate the transport of the quick-change positioning disk 2.

[0042] In this embodiment, see Figure 1 As a preferred design, the wrench placement seat 7 has multiple placement positions, and different specifications of adjustment wrenches 8 are placed on different placement positions. The control mechanism 9 can control the manipulator 3 to drive the clamping mechanism 5 to the designated placement position to grab the corresponding adjustment wrench 8 according to actual needs.

[0043] In this embodiment, see Figure 1 As a preferred design, the manipulator 3 is a multi-axis manipulator 3 with multi-degree-of-freedom movement. Specifically, an existing mature intelligent manipulator 3 product can be used, which can drive the clamping mechanism 5 to move flexibly, so as to accurately grasp the adjusting wrench 8 and insert the adjusting wrench 8 into the screw of the boring tool 12.

[0044] In this embodiment, see Figure 1 As a preferred design, the rotary drive mechanism 4 includes a servo motor, which is fixedly connected to the manipulator 3, and the clamping mechanism 5 is installed on the output shaft of the servo motor. The servo motor has a good rotation angle control accuracy, so that the rotation angle of the adjustment wrench 8 can be accurately controlled to ensure accurate adjustment of the boring tool 12. The clamping mechanism 5 can adopt an existing suitable mechanism that can automatically and stably clamp the wrench.

[0045] In this embodiment, see Figure 1 The energy storage mechanism 10 has a charging interface including a battery for storing electric energy to provide electric energy for the movement of the manipulator 3, and can also supply power to other parts of the tool adjustment device such as the rotary drive mechanism 4, the clamping mechanism 5, the visual recognition mechanism 6, and the control mechanism 9 that need electricity. As a preferred design, the energy storage mechanism 10 has a charging interface to charge the battery. After the boring tool 12 is adjusted, the handling robot moves the quick-change positioning plate to the position waiting for work and charges it.

[0046] As can be seen from the above, the tool adjustment device of the utility model has the following beneficial effects:

[0047] 1. It can be used for automatic adjustment of boring tools 12 and other tools. Existing visual technology can be used to position and align the tool and the adjusting wrench 8, and the adjusting wrench 8 can be automatically rotated to adjust the tool, thereby realizing automated work, reducing labor costs, and improving tool preparation efficiency.

[0048] 2. Through the quick-change positioning mechanism, the tool adjustment device can be quickly installed or disassembled on the machine tool. It is suitable for the manufacturing industry based on the quick-change positioning mechanism clamping, especially for the intelligent production line with the quick-change positioning mechanism as the clamping method.

[0049] 3. It has a wide range of uses and can be used for adjusting various fine boring cutters 12, and can also be used for other similar cutters that can be adjusted by various wrenches, thereby reducing the number of cutters and saving cutter costs.
