In addition, the terms "one", "first", "second", "third", "fourth", "fifth", "sixth" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0036] See also Figures 1 to 10 , the present invention provides a technical solution:

[0037] Embodiment 1, an automatic appearance detection device for a tool used for aviation precision machining, comprises: a workbench 1, a mounting block 4 and a clamping block 7.

[0038] Specifically, a drill tool 3 is arranged above the workbench 1, and the structure of the drill tool 3 is as follows: Figure 4 and Figure 7 As shown, the drill tool 3 itself is a columnar structure, and a plurality of spiral grooves distributed in a circular array are opened on the surface. The drill tool 3 is a prior art known in the art, such as a press-fit hexagonal shank and square shank drill with press-fit and torque enhancement disclosed in publication number CN211758732U. A detector 2 is arranged on the outside of the drill tool 3, and the detector 2 is used to perform appearance inspection on the drill tool 3. The detector 2 is a prior art known in the art, and a CCD camera and a light source lamp are arranged at the front end thereof, such as a precise high-end appearance inspection instrument for tool production disclosed in publication number CN217981215U.

[0039] Secondly, the mounting block 4 is located on the upper side of the workbench 1, and the drill tool 3 is placed on the upper side of the mounting block 4. The position of the mounting block 4 itself can be adjusted according to actual use, so as to change the position of the drill tool 3. A mounting plate 5 is fixedly installed on the side of the mounting block 4, and two sets of supporting wheels 6 are rotatably installed on the upper surface of the mounting plate 5, and the drill tool 3 is placed between the two sets of supporting wheels 6 from top to bottom, and the supporting wheels 6 are tilted. Figure 2 and Figure 7As shown, the drill cutter 3 can be located between the two groups of support wheels 6 by its own gravity. When the drill cutter 3 is pressed down and compacted, friction can be generated between the drill cutter 3 and the support wheels 6. At this time, the rotation of the drill cutter 3 can drive the support wheels 6 to rotate accordingly. However, since the support wheels 6 themselves are inclined, the support wheels 6 can transport the drill cutter 3 when rotating, so that the drill cutter 3 can move along its own length direction, thereby ensuring that each position on the surface of the drill cutter 3 can be detected by the detector 2 above it.

[0040] Furthermore, the clamping block 7 is located above the drill bit 3, and a rolling body 71 is movably embedded at the lower end of the clamping block 7, and the rolling body 71 is stuck in the spiral groove on the surface of the drill bit 3 from top to bottom. There is no contact between the clamping block 7 and the drill bit 3, and the rolling body 71 can roll in the spiral groove on the surface of the drill bit 3. Clamping rollers 8 are rotatably installed on both sides of the clamping block 7, and the clamping rollers 8 are pressed on the outer side of the drill bit 3 from top to bottom. After the clamping rollers 8 press the drill bit 3 downward, the drill bit 3 will not come off. The pressing roller 8 can drive the drill bit 3 to rotate by the friction between it and the drill bit 3, but because the pressing block 7 will not move in the length direction of the drill bit 3, when the drill bit 3 rotates, the spiral groove on the surface of the drill bit 3 cooperates with the rolling body 71 to drive the drill bit 3 to move along its own length direction, and the moving direction is consistent with the direction in which the support wheel 6 drives the drill bit 3 to move, so that the rolling body 71 can be prevented from detaching from the spiral groove on the surface of the drill bit 3;

[0041] In combination with the above, it can be seen that the drill tool 3 of the present device can be driven to rotate by the clamping roller 8, and the drill tool 3 can also move along its own length direction during rotation, so that each area of ​​its own surface can be detected by the detector 2, ensuring that the appearance inspection of the drill tool 3 is more comprehensive and accurate.

[0042] The movable arm 9 is fixedly connected to the outer side of the clamping block 7, and a support block 91 is fixedly connected to the middle part of the lower surface of the movable arm 9. A support frame 10 is arranged below the support block 91, and the two are rotatably connected. The movable arm 9 can rotate around the upper end of the support frame 10, thereby driving the clamping block 7 to rotate and move. By rotating the clamping block 7 upward, the clamping roller 8 can be separated from the drill bit 3 to facilitate the removal of the drill bit 3. Conversely, the clamping block 7 can be rotated downward to press and position the drill bit 3. A reset torsion spring 92 is arranged between the side of the support block 91 and the inner wall of the support frame 10. The reset torsion spring 92 provides torque to drive the clamping block 7 to always have a tendency to rotate downward, thereby ensuring that the clamping roller 8 can automatically press the drill bit 3. The support frame 10 is fixedly installed on the surface of the mounting block 4.

[0043] In order to install the clamping roller 8, the present application also has a rotating shaft 72 movably penetrating the lower end of the clamping block 7, and the two clamping rollers 8 are respectively fixedly sleeved on the outer sides of the two ends of the rotating shaft 72, and the rotating shaft 72 is kept parallel to the drill bit tool 3 to ensure that the two clamping rollers 8 can be pressed on the surface of the drill bit tool 3. The length of the clamping roller 8 is greater than the width of the spiral groove on the surface of the drill bit tool 3. Figure 4 As shown, the pressure roller 8 can avoid getting stuck in the spiral groove on the surface of the drill bit tool 3. The surface of the pressure roller 8 only contacts the surface of the drill bit tool 3, and the friction force generated between the two ensures that the pressure roller 8 can drive the drill bit tool 3 to rotate. A rounded corner is also provided at the edge of the surface of the pressure roller 8 to avoid the edge of the pressure roller 8 from scraping against the edge of the spiral groove on the surface of the drill bit tool 3. Concave grooves 73 are provided on both sides of the pressure block 7. A driven wheel 74 and a driving wheel 75 are movably provided at the bottom of the concave groove 73. The driven wheel 74 and the driving wheel 75 are connected by a belt. The driven wheel 74 is fixedly sleeved on the outer side of the rotating shaft 72. Figure 5 As shown, the driving wheel 75 and the driven wheel 74 rotate at the same speed, thereby driving the rotating shaft 72 and the pressure roller 8 to rotate.

[0044] In order to drive the pressing roller 8 to rotate, the present application also has a double-axle extension motor 76 installed in the upper inner cavity of the pressing block 7, and the two ends of the rotating shaft of the double-axle extension motor 76 are respectively fixedly connected to the two driving wheels 75, such as Figure 5 As shown, when the double-axle extension motor 76 is working, it can drive the two driving wheels 75 to rotate synchronously, thereby stably driving the clamping roller 8 to rotate. The upper end of the clamping block 7 is fixedly connected to a clamping cover 77 by bolts, and the clamping cover 77 clamps and positions the double-axle extension motor 76 from top to bottom. The lower surface of the clamping cover 77 is provided with a clamping block, and the lower surface of the clamping block is in a concave arc shape, which is used to match the surface of the double-axle extension motor 76. When the clamping cover 77 is close to the clamping block 7, the clamping block can clamp and position the double-axle extension motor 76. Conversely, when the double-axle extension motor 76 fails and needs to be replaced, it only needs to remove the clamping cover 77 from the upper end of the clamping block 7 to remove the double-axle extension motor 76 from the inner cavity at the upper end of the clamping block 7.

[0045] In order to limit the position of the support wheel 6, the support wheel 6 of the present application is provided with multiple support wheels 6 and is linearly distributed at equal intervals along the length direction of the drill bit 3, so as to stably support the drill bit 3. The spacing between two adjacent support wheels 6 is the same as the spacing between two adjacent spiral grooves on the surface of the drill bit 3. The support wheel 6 is in contact with the surface of the drill bit 3 and is staggered with the spiral grooves on the surface of the drill bit 3. Figure 7 As shown, the support wheel 6 only contacts the surface of the drill bit 3 and does not fall into the spiral groove on the surface of the drill bit 3.

[0046] In order to install the support wheel 6, the present application also has a stand 61 installed on the outer side of the support wheel 6 for supporting and positioning the support wheel 6. The two ends of the lower surface of the stand 61 are respectively fixedly connected with a connecting pin 62 and a positioning shaft 63. The positioning shaft 63 is stepped and has a length greater than the connecting pin 62. The lower end of the positioning shaft 63 is movably plugged into the surface of the mounting plate 5 and rotatably connected thereto. A gap is left between the lower end surface of the connecting pin 62 and the surface of the mounting plate 5. Figure 8 and Figure 7 As shown, the stand 61 and the mounting plate 5 are rotatably connected, and the rotation center is the positioning axis 63, that is, the connecting pin 62 can rotate around the positioning axis 63 without scratching the surface of the mounting plate 5, so the inclination angle of the support wheel 6 itself can be adjusted, and in the process of adjusting the inclination angle of the support wheel 6, the horizontal spacing between the support wheel 6 and the clamping block 7 can also be changed accordingly. The advantage of this design is that when the rolling body 71 is stuck in the spiral groove on the surface of the drill tool 3, the position of the spiral groove on the surface of the drill tool 3 is determined, but for drill tools 3 of different sizes, the surface The spacing of the spiral grooves is different. Therefore, in order to avoid the support wheel 6 from getting stuck in the spiral grooves on the surface of drill bits 3 of different sizes, the position of the support wheel 6 needs to be adjusted according to actual use. In addition, for drill bits 3 of different sizes, when the diameter of the drill bit 3 increases, the stability of the drill bit 3 when placed can be effectively improved by appropriately increasing the spacing between the two groups of support wheels 6. When the support wheel 6 is adjusted, its moving trajectory is exactly an arc. Therefore, the two groups of support wheels 6 can move away from each other to adapt to the drill bit 3 with a larger diameter and ensure its stability when placed.

[0047] In order to synchronously adjust the positions of multiple support wheels 6 of the same group, the present application also has a linkage rod 51 movably arranged on the surface of the mounting plate 5, and one side of the linkage rod 51 is fixedly connected to multiple connecting rings 52 that are linearly distributed at equal intervals. The connecting ring 52 is located between the stand 61 and the mounting plate 5, and the upper and lower sides of the connecting ring 52 are respectively in contact with the lower surface of the stand 61 and the upper surface of the mounting plate 5, thereby ensuring that the stand 61 can only rotate in the horizontal direction, and the connecting ring 52 is movably sleeved on the outside of the connecting pin 62, so that the linkage rod 51 can drive the multiple support wheels 6 of the same group to move synchronously when moving, thereby ensuring that the multiple support wheels 6 of the same group are always distributed along the length direction of the drill tool 3.

[0048] In order to position and adjust the linkage rod 51, the present application also has a positioning protrusion 53 fixedly connected to the other side of the linkage rod 51, such as Figure 7As shown, the surface of the mounting plate 5 is provided with an adjustment slot 56 corresponding to the positioning protrusion 53, and the adjustment slot 56 is arc-shaped, and a fastening bolt 54 is movably provided through the middle of the positioning protrusion 53, and the fastening bolt 54 is inserted into the inner cavity of the adjustment slot 56, and the cross-section of the adjustment slot 56 is in a "convex" shape, and an adjustment slider 55 is slidably installed at the bottom of the slot, and the lower end of the fastening bolt 54 passes through the middle of the adjustment slider 55 through a thread, as shown in FIG. Fig. 9 and Fig.10 As shown, the adjusting slider 55 can only slide in the inner cavity of the adjusting slot 56 along the length direction of the adjusting slot 56, and will not detach from the inner cavity of the adjusting slot 56. When the fastening bolt 54 is tightened to make the adjusting slider 55 and the positioning protrusion 53 approach each other, the adjusting slider 55 can position the linkage rod 51 through the friction force generated between the adjusting slider 55 and the inner wall of the adjusting slot 56. Conversely, when the fastening bolt 54 is loosened to make the adjusting slider 55 and the positioning protrusion 53 move away from each other, the linkage rod 51 can move, thereby adjusting the position of the support wheel 6. In addition, friction grooves are provided on the upper surface of the adjusting slider 55 to increase the friction force generated between the adjusting slider 55 and the inner wall of the adjusting slot 56, so as to prevent the adjusting slider 55 from easily sliding in the inner cavity of the adjusting slot 56 after the fastening bolt 54 is tightened.

[0049] In order to adjust the position of the mounting block 4, the present application also has a sliding seat 41 installed at the lower end of the mounting block 4, and the two are kept fixed, a slide rail 42 is provided on the lower side of the sliding seat 41, and the sliding seat 41 and the slide rail 42 are slidably connected, the sliding seat 41 can slide along the length direction of the slide rail 42, thereby driving the mounting block 4 to change its position, a rotating seat 43 is provided below the slide rail 42, and the rotating seat 43 is fixed to the surface of the workbench 1, a rotating table 44 is rotatably installed on the upper side of the rotating seat 43, the slide rail 42 is fixed to the upper surface of the rotating table 44, and the rotating table 44 can rotate horizontally around the circle of the rotating seat 43, thereby further changing the position of the mounting block 4.

[0050] In order to determine the distribution position of the detector 2, the present application is provided with two detectors 2, which are respectively facing the end face and the surface of the drill bit tool 3, and the two detectors 2 are vertically distributed to each other, such as Figure 1 As shown, the two detectors 2 are respectively used to perform appearance inspection on the end face and surface of the drill tool 3. A display 11 is arranged on the surface of the workbench 1, and the two detectors 2 are electrically connected to the display 11. The display 11 is used to display the image detected by the detector 2 in real time for confirmation by the staff.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
