DETAILED DESCRIPTION

[0028] The technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment.

[0029] Please refer to Figures 1-4 A three-coordinate detection machine probe structure with protection function, including guide frame 2, guide frame 2 is provided with probe body 1 in it:

[0030] Two groups of guide slides 3 are opened in the outer wall surface of guide frame 2;

[0031] Two protection frames 4, the front and back two wall surfaces of the inner wall are fixedly installed with two groups of limit sliding blocks 5 matched with guide slides 3, the left and right two side surfaces of the inner wall surface are fixedly installed with support frames 6;

[0032] Two groups of limit guide rods 7, the roots are fixedly installed on the two side surfaces inside guide frame 2;

[0033] Two groups of cylinders 8, the connecting end is fixedly installed with sliding sleeve 9 slidably connected with limit guide rod 7, the telescopic end is fixedly installed on the upper wall surface of support frame 6.

[0034] In use, the guide frame 2 provides a mounting base for the protective structure; when the air cylinder 8 extends or retracts, the protective frame 4 is driven to move along the guide slide 3 through the limiting slide block 5, and at the same time, the protective frame 4 is driven to slide along the limiting guide rod 7 through the sliding sleeve 9, so as to realize the opening and closing of the protective frame 4; when the protective frame 4 is opened, it does not affect the working of the probe body 1, and when it is not detected, it is closed to form a protective barrier to avoid the probe body 1 from being collided; the limiting guide rod 7 cooperates with the sliding sleeve 9 to ensure that the air cylinder 8 extends or retracts stably, and then ensures that the protective frame 4 moves accurately, and improves the reliability of the protective structure.

[0035] Please refer to Figure 3 The guide frame 2 and the front and rear walls of the two protective frames 4 are provided with magnetic attraction grooves 10, and the magnetic attraction grooves 10 are fixedly installed with magnetic attraction pieces 11; the magnetic attraction pieces 11 on the protective frame 4 are composed of two parts and are installed on the two protective frames 4 respectively, and when the two protective frames 4 are combined, a circular structure is formed; in use, the magnetic attraction grooves 10 and the magnetic attraction pieces 11 provide quick adsorption fixing points for the telescopic sleeve 12, and the installation of the telescopic sleeve 12 can be completed without bolts and other fasteners, and the telescopic sleeve 12 can be separated only by applying external force, which greatly improves the disassembly efficiency of the protective auxiliary component; the magnetic adsorption mode can ensure that the telescopic sleeve 12 is tightly attached to the guide frame 2 after installation, avoiding loosening when the detection machine moves.

[0036] Please refer to Figure 4 The telescopic sleeve 12 is adsorbed in the magnetic attraction groove 10, the sliding piece 13 is slidably connected in the telescopic sleeve 12 along the axial direction, and the bottom wall of the telescopic sleeve 12 and the rear wall of the sliding piece 13 are fixedly installed with the reset spring 14; in use, the reset spring 14 always applies a forward thrust to the sliding piece 13, so that the sliding piece 13 remains in the extended state and expands the protection range; when the protective plate 16 is collided, the sliding piece 13 can be retracted axially along the telescopic sleeve 12, and the impact force is buffered through the elastic deformation of the reset spring 14, avoiding the direct transmission of external force to the protective frame 4, forming a double protection effect of "rigid protection + elastic buffering".

[0037] Please refer to Figure 1 The telescopic sleeve 12 has magnetism at the root and can be adsorbed with the magnetic attraction piece 11; in use, when the probe body 1 is not used, the telescopic sleeve 12 is adsorbed in the magnetic attraction groove 10 in the protective frame 4 to enhance the protection effect, and when the probe body 1 is used, the telescopic sleeve 12 is adsorbed in the magnetic attraction groove 10 in the guide frame 2 to avoid the loss of the protective plate 16 after the probe body 1 is used.

[0038] Please refer to Figure 4 The front wall of the sliding piece 13 is fixedly installed with the supporting rod 15, and the supporting rod 15 is fixedly installed with the protective plate 16; in use, the supporting rod 15 provides stable support for the protective plate 16, so that the protective plate 16 can cover the key area of the probe body 1.

[0039] Please refer to Figure 4The rear wall surface of the protection plate 16 is fixedly provided with a buffer pad 17; in use, the buffer pad 17 is made of elastic material (such as rubber, foam), when the protection plate 16 is impacted, the buffer pad 17 can further absorb the impact force, reduce the influence of the impact on the protection plate 16, the supporting rod 15 and the probe body 1, especially can avoid the precision deviation of the probe body 1 caused by hard contact, and ensure the detection accuracy of the three-coordinate detection machine.

[0040] Please refer to Figure 3 Both groups of guide slides 3 are turning slides; in use, the guide slides 3 can guide the protection frame 4 to realize direction conversion when moving, improve the opening and closing range of the protection frame 4 along the guide frame 2, and avoid interference caused by the probe body 1 when working.

[0041] Please refer to Figure 3 The two side surfaces of the guide frame 2 are provided with an air avoidance groove 18 for supporting the movement of the support frame 6; in use, the air avoidance groove 18 provides movement space for the support frame 6 of the protection frame 4, avoids collision or interference between the support frame 6 and the side wall of the guide frame 2 when the support frame 6 slides with the protection frame 4, ensures smooth movement of the protection frame 4 along the guide slide 3, does not appear jamming phenomenon, and guarantees the continuity of the opening and closing action of the protection structure.

[0042] In example 1, the protection frame 4 is driven by the air cylinder 8 to move along the guide slide 3, realizes opening and closing freely during detection, does not interfere with the work of the probe body 1, and can provide protection at any time, ensuring the detection accuracy and the safety of the probe body 1.

[0043] Specifically, before detection, two air cylinders 8 are started, the telescopic ends of the air cylinders 8 pull the support frames 6 of the two protection frames 4, the protection frames 4 slide along the two groups of guide slides 3 of the guide frame 2 through the limiting sliding blocks 5 on the inner walls, and the sliding sleeves 9 at the connecting ends of the air cylinders 8 move stably along the limiting guide rods 7; the air avoidance grooves 18 on the two sides of the guide frame 2 provide movement space for the support frames 6, avoiding interference; the protection frame 4 opens to both sides along the guide slide 3, completely exposes the detection end of the probe body 1, and does not affect the detection work of the probe body 1 on the workpiece. If temporary protection is needed during detection, the air cylinders 8 are started in reverse, the protection frame 4 quickly closes to form a semi-enclosed barrier; after detection, the protection frame 4 is completely closed, and the magnetic attraction piece 11 in the magnetic attraction groove 10 is adsorbed and fixed, preventing the probe from being damaged by external impact.

[0044] In example 2, the telescopic sleeve 12 adsorbs to expand the protection range, and the double buffering of the reset spring 14 and the buffer pad 17 realizes the all-round protection of the probe body 1 in the non-detection state, avoiding the precision deviation caused by the impact.

[0045] Specifically, when not detecting, the telescopic sleeve 12 with a magnetic root is adsorbed in the magnetic adsorption groove 10 on the front and rear walls of the protective frame 4 and is fixed in close contact with the magnetic adsorption sheet 11. The reset spring 14 in the telescopic sleeve 12 pushes the sliding sheet 13 to extend out, and through the cooperation of the supporting rod 15 and the protective plate 16, an impact protection barrier for the protective frame 4 is formed. If the protective plate 16 is impacted, the sliding sheet 13 is retracted along the axis of the telescopic sleeve 12, and the reset spring 14 further buffers and absorbs the shock, so that the external force is not transmitted to the probe body 1, and at the same time, the buffer pad 17 on the rear wall further absorbs part of the impact force. When the probe needs to be used, the telescopic sleeve 12 can be taken off from the magnetic adsorption groove 10 of the protective frame 4 and is adsorbed in the magnetic adsorption groove 10 of the guide frame 2 for storage, which does not affect the detection and can avoid the loss of the protective plate 16.

[0046] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
