Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling positioning device for machining engine parts. Background Art

[0002] A drilling machine refers to a machine tool that mainly uses a drill to process holes on a workpiece. Due to the large number of engine parts, different parts often need to be fixed and assembled. At this time, a drilling machine is needed to open mounting holes on the engine parts to facilitate the fixed assembly of the engine parts. When drilling parts, a drilling positioning device for engine parts processing is used.

[0003] The "Drilling Device for Processing Engine Parts" with application number "202320581469.3" has been disclosed on the Chinese Patent Network. In this patent, an auxiliary positioning device is provided, and when the engine parts are fixed on the workpiece fixture, the position of the engine parts to be drilled can be aligned with the positioning through hole provided on the auxiliary positioning device. Since the positioning through hole is directly below the drilling bit, the position of the engine parts to be drilled aligned with the positioning through hole will also be directly below the drilling bit. At this time, during the drilling process, the drilling bit can accurately drill holes at the positions of the engine parts to be drilled, thereby improving the drilling accuracy of the engine parts, and further increasing the fixed assembly accuracy between the engine parts. However, in this patent, the auxiliary positioning device is used to coincide with the drilling position of the drilling machine, and at the same time, the drilling machine can pass through the auxiliary device to achieve When it comes to the precise positioning of drilling, because of the auxiliary positioning device, there is a circular hole in the middle. The drilling position is judged through the circular hole. Its height is at a certain height from the surface of the part, resulting in the overshoot of the judgment of the center position of the circle. The user's field of vision generally judges the precise processing position of the part through an inclined perspective. The deviation of the field of vision will cause a deviation in the drilling position of the part, resulting in reduced accuracy. If the user's eyes are kept vertically to the circular hole for observation and precise positioning, the user's eyes need to keep the circular hole vertical, and the user's head will be at the bottom of the drilling machine, causing the user to be in a dangerous state, reducing the user's safety. Alternatively, the drilling machine is moved down to determine the position, which is cumbersome and inconvenient to adjust the processing position of the part. The user needs to clamp and fix the part again, increasing the number of part fixations, which will inevitably cause damage to the part and reduce the qualified rate of the part.

[0027] The following is combined with Figure 1-8 To further explain this application in detail,

[0028] The present application embodiment discloses a drilling positioning device for engine parts processing.

[0029] The positioning mechanism 5 includes a support rod 501, which is fixedly mounted on the surface of the support frame 16. A rotation groove 502 is provided on the surface of the support rod 501. A positioning plate 503 is rotatably connected to the inner cavity of the rotation groove 502. A laser pen 504 is fixedly mounted on the inner wall of the positioning plate 503.

[0030] The adjusting mechanism 6 includes a movable groove 601, which is opened on the top of the workbench 1. A motor 602 is fixedly installed on one side of the workbench 1. A rotating rod 603 is fixedly installed on the output end of the motor 602. The rotating rod 603 penetrates into the inner cavity of the movable groove 601. The surface of the rotating rod 603 is threadedly connected with a mounting platform 604. A sliding groove 605 is opened on the top of the mounting platform 604. An electric telescopic rod 606 is fixedly installed on the inner wall of the sliding groove 605. A fixed platform 607 is fixedly installed on one end of the electric telescopic rod 606.

[0031] Reference Figure 3 and Figure 4 The inner wall of the movable groove 601 is provided with a guide groove 7, and a guide block 8 is fixedly installed on the surface of the mounting platform 604. The inner cavity of the guide groove 7 is slidably connected to the surface of the guide block 8. Through the sliding connection between the guide groove 7 and the guide block 8, the movement of the mounting platform 604 can be guided, so that the mounting platform 604 can move horizontally;

[0032] Reference Figure 4 The inner wall of the movable groove 601 is provided with a rotating shaft 9, and the surface of the rotating rod 603 is rotatably connected with the inner wall of the movable groove 601 through the rotating shaft 9. By providing the rotating shaft 9, the rotating rod 603 and the inner cavity of the movable groove 601 can be rotated, and the friction force is reduced, so that the rotating rod 603 can rotate more smoothly;

[0033] Reference Figure 7 A positioning groove 10 is provided on the inner wall of the rotating groove 502, and a positioning block 11 is fixedly installed on the inner wall of the positioning plate 503. The surface of the positioning block 11 is slidably connected with the inner cavity of the positioning groove 10. The sliding connection between the positioning groove 10 and the positioning block 11 can limit the rotation angle of the positioning plate 503, so that the positioning plate 503 can rotate between 0° and 90°. When the positioning plate 503 is at 90°, the point irradiated by the laser pen 504 coincides with the drilling point of the drilling machine 4, which can reduce the docking time between the irradiation point of the laser pen 504 and the drilling point of the drilling machine 4, and realize the rapid and accurate positioning of the laser pen 504.

At the same time, the spring 14 is compressed. When the positioning plate 503 moves 90°, the opening of the limit groove 15 overlaps with the opening of another fixing groove 12. Under the reaction force of the spring 14, the other limit button 13 is driven to enter the inner cavity of the limit groove 15, so as to fix the rotating positioning plate 503 and ensure the stability of the limit plate when working.

At the same time, the laser is in contact with the surface of the part, so that the user can clearly see the point where the drilling machine 4 falls, and the precise positioning of the part drilling point is achieved, which increases the accuracy of the part drilling. When the part is fixed, the laser irradiation When the point and the drilling point are offset, the motor 602 is started, and the rotating rod 603 is driven by the motor 602 to rotate, so that the mounting table 604 can move horizontally left and right in the inner cavity of the movable hole, and the water position of the part can be adjusted. The fixed table 607 is driven by the electric telescopic rod 606 to move, and the fixed table 607 can be adjusted horizontally front and back in the inner cavity of the sliding groove 605, so as to adjust the drilling position of the part.
