Description

TECHNICAL FIELD

[0001] The utility model belongs to microscope device technical field, concretely relates to a high-precision swing arm microscope device. BACKGROUND

[0002] In the CNC machining and manufacturing die industry, the sharpness, average degree and smoothness of the blade are crucial. Sharpness determines whether the die can cleanly cut off the material when punching the product, ensuring that the cutting edge is neat and burr-free; average degree reflects the consistency of the blade in all parts, and if the sharpness of different parts of the blade varies greatly, the punching effect may be good in some areas but not in others, or tearing may occur; smoothness is related to the quality of the blade surface, and rough blades not only affect the punching effect but also may accelerate blade wear and shorten the service life of the die. Therefore, these characteristics directly affect the final punching effect and are key indicators of die quality.

[0003] When machining and repairing the blade on a CNC machine, detecting the blade is an indispensable and critical step. Because during the machining process, even if the CNC equipment has high precision, the actual state of the blade may deviate from the expected due to factors such as tool wear and machining parameter fluctuations. Only through accurate detection can it be determined whether the blade has reached the required sharpness, average degree and smoothness standards, and the machining process can be adjusted to ensure that the die quality is qualified. If the detection link fails, such as failing to accurately determine the problems with the blade, it may lead to a series of serious consequences, such as the die not meeting quality requirements and becoming a defective product, which cannot be used and must be reworked. This not only wastes previous processing time and material costs, but also delays product delivery, affects enterprise reputation and customer satisfaction, increases production costs, reduces production efficiency, and causes significant losses to the enterprise.

[0004] When manually detecting the blade with a manual microscope, some surface conditions of the blade can be observed directly, but the operation relies on manual adjustment of the microscope's focal length, stage position and other parameters to find the appropriate observation field of view, and the naked eye is used to judge whether the blade's characteristics meet the standards. This has a large subjective element, and different detection personnel may have different standards for judging sharpness and average degree, and long-term observation can lead to visual fatigue, affecting the accuracy of detection. In addition, the detection efficiency of a manual microscope is relatively low, and for mass-produced dies, manual microscope detection one by one will consume a lot of time and is not conducive to improving production efficiency.

[0005] The hand feeling detection is a relatively rough way, and a detection personnel roughly feels the sharpness and smoothness of the blade by touching the blade with hands. This way completely depends on the experience and tactile perception of the individual, and the accuracy is extremely low. The hand feeling sensitivity of different people is different, and the judgment result is quite different. Moreover, it is difficult to accurately judge the average degree of the blade by hand feeling. More importantly, touching the blade with hands is dangerous, and it is easy to scratch fingers and cause safety accidents. Practical new type content

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] To address the issues of poor stability and accuracy in existing manual microscopes or manual blade inspection, this invention provides a high-precision swing-arm microscope device. This device is easy and quick to install, improving inspection efficiency. Simultaneously, it precisely and automatically adjusts the measurement position, significantly enhancing the accuracy of blade inspection and ensuring the quality of the cutting die.

[0040] like Figure 1 As shown, the high-precision swing-arm microscope device provided in this embodiment includes: a mounting base 10 and a multi-axis rotating arm 20. The mounting base 10 is magnetically mounted on a CNC machine tool. The first end of the multi-axis rotating arm 20 is rotatably connected to the mounting base 10, and the second end of the rotating arm is movably connected to the microscope.

[0041] In this embodiment, the mounting base 10 is magnetically mounted on the CNC machine tool in conjunction with the multi-axis rotating arm 20, making the mounting base 10 detachable. This allows the microscope device to be detachably mounted on the CNC machine tool, enabling rapid installation and removal of the microscope device and improving inspection efficiency. Furthermore, the position of the microscope can be adjusted using the multi-axis rotating arm 20 and / or the mounting base 10 as needed to detect the blade edge, achieving precise and automatic adjustment of the measurement position. This significantly improves the accuracy of blade edge detection, thereby ensuring the quality of the die.

[0042] In this embodiment, the specific structure of the mounting base 10 has been optimized.

[0043] like Figure 2 As shown, the mounting base 10 includes a magnetic base 11 and a connecting base 12. The magnetic base 11 is connected to the connecting base 12. The magnetic base 11 has an on / off switch 111 that controls the magnetic base 11 to be in an engaged or closed state. When the magnetic base 11 is in an engaged state, the connecting base 12 is magnetically connected to the CNC machine tool.

[0044] Further, the magnetic seat 11 is nested with the connecting seat 12, the top of the connecting seat 12 is provided with a first rotating part 121, and the first end of the multi-axis rotating arm 20 is rotationally connected with the first rotating part 121.

[0045] Specifically, the side wall of the connecting seat 12 is provided with a mounting groove matched with the magnetic seat 11, and the magnetic seat 11 can be magnetically mounted in the mounting groove.

[0046] As a preferred embodiment, the on-off key 111 can be a switch knob or a switch button, and the magnetic seat 11 can be an electromagnetic magnetic seat or a permanent magnetic magnetic seat.

[0047] In the embodiment, when the magnetic seat 11 is an electromagnetic magnetic seat, it mainly consists of a core, a coil, an armature, a shell and the like. The core is located at the center of the magnetic seat, the coil is wound around the core, the armature is a movable part connected with the external connecting structure, and the shell plays a role of protecting and fixing the internal components.

[0048] When the circuit is turned on through the on-off key 111, the current passes through the coil, and according to the principle of electromagnetic induction, a magnetic field is generated around the coil. After the core is magnetized, its magnetic field intensity is greatly enhanced, generating a strong magnetic force. The magnetic force attracts the armature, making the armature move towards the core until it is in close contact with the core. At this time, the magnetic force between the armature and the core firmly attracts the magnetic seat 11 to the connecting seat 12, further firmly attracting the connecting seat 12 to the CNC machine, realizing the attraction function of the magnet.

[0049] When the circuit is turned off through the on-off key 111, there is no current passing through the coil, and the magnetic field disappears. The armature separates from the core under the action of its own gravity or other external forces, and the magnetic force of the magnetic seat 11 disappears, so as to realize the closing of the magnet, facilitate the removal of the magnetic seat 12 from the connecting seat 12, and further facilitate the removal or position adjustment of the connecting seat 12 from the CNC machine.

[0050] In some optional embodiments, when the magnetic seat 11 is a permanent magnetic magnetic seat, it mainly consists of a permanent magnet, a magnetic yoke, a handle, a shaft and the like. The permanent magnet is the core component for generating magnetic force, the magnetic yoke is used for guiding and concentrating the magnetic force lines of the permanent magnet, and the handle is connected with the internal magnetic circuit structure through the shaft for manual operation.

[0051] The on-off key 111 is a linkage mechanism with the handle or an indication button.

[0052] In the initial state, the handle is in the initial position, at this time the magnetic force lines of the permanent magnet form a closed loop through the magnetic yoke, the magnetic force is mainly concentrated inside the magnetic seat, and the external magnetic force is weak or almost non-existent. When the key 111 is operated and the handle is turned to another position, the direction of the magnetic force lines of the permanent magnet changes, and the magnetic force lines diverge outward through the magnetic yoke and the external connecting structure, so that the magnetic seat 11 exhibits strong magnetic force to the outside, thereby being attracted to the connecting seat 12, and further making the connecting seat 12 firmly attached to the CNC machine table, thereby realizing the attraction of the magnet.

[0053] To turn off the magnetic force of the magnetic seat 11, the handle is returned to the initial position by operating the key 111 again, the magnetic force lines of the permanent magnet change path again, and the external magnetic force is weakened or disappears. The magnetic seat 11 can be easily removed from the connecting seat 12, and further the connecting seat 12 can be removed from the CNC machine table or adjusted in position.

[0054] Therefore, the high-precision swing arm microscope device of the embodiment is magnetically attached to the CNC machine table through the mounting seat 10, so that the mounting seat 10 is detachable, and the microscope device is detachably mounted on the CNC machine table, thereby realizing quick mounting and dismounting of the microscope device, improving detection efficiency, and adjusting the position of the microscope according to the position of the blade to be detected, thereby realizing precise automatic adjustment of the measurement position and greatly improving the precision of the blade detection, thereby ensuring the quality of the blade mold.

[0055] The mounting seat 10 is a basic fixed component of the entire device, which is magnetically attached to the CNC machine table through the magnetic seat 11, and the key 111 is used to control the attraction and closing of the magnet in the magnetic seat 11. By operating the key 111, the magnetic seat 11 can be turned on and off, thereby realizing the mounting and dismounting of the entire device. The magnetic seat 11 cooperates with the connecting magnet, which balances the magnetic force distribution of the magnet and ensures the stability and reliability of the device during adsorption or fixation, thereby avoiding position deviation or instability caused by uneven adsorption.

[0056] In the embodiment, the high-precision swing arm microscope device further comprises a microscope mounting tube 30, the upper end of the microscope mounting tube 30 is movably connected with the second end of the multi-axis rotating arm 20, and the lower end of the microscope mounting tube 30 is fixedly connected with a microscope.

[0057] Specifically, the second end of the multi-axis rotating arm 20 is provided with a through hole, the upper end of the microscope mounting tube 30 passes through the through hole and is movable along the through hole in the longitudinal direction, and the microscope mounting tube 30 is locked and fixed with the second end of the multi-axis rotating arm 20 by the first locking member 40.

[0058] The first locking member mainly comprises a first rotating handle. When the position of the microscope mounting tube 30 needs to be adjusted, the first locking member 40 is loosened, so that the microscope mounting tube 30 moves along the through hole in the longitudinal direction, thereby adjusting the height of the microscope, and then the first locking member 40 is locked and fixed.

[0059] In addition, a sensor and a light source module are arranged on the microscope mounting tube 30. The sensor is used to obtain the detection height of the microscope, and the light source module is used to provide the detection brightness for the microscope.

[0060] Therefore, in the embodiment, the light source module is used to control the brightness, so as to provide good illumination conditions for the microscope, so that the detection personnel can clearly observe the details of the detected object, thereby improving the detection precision and efficiency. The sensor mainly adopts a probe inductor, which is used to monitor the measurement height of the microscope, so as to adjust the installation height of the microscope mounting tube 30 through the sensed related parameters, thereby realizing accurate adjustment of the position of the microscope, ensuring that the microscope is at a suitable height during detection, and obtaining accurate detection results.

[0061] The embodiment as the preferred embodiment also optimizes the specific structure of the multi-axis rotating arm 20.
