Description

Technical Field

[0001] The present invention relates to the technical field of positioning drilling, and in particular to a positioning drilling device for mechanical castings. Background Art

[0002] A casting is a process in which molten metal is poured into a mold cavity that conforms to the shape and dimensions of a part. After it cools and solidifies, a blank or part is obtained. Some castings require drilling during the processing.

[0003] For example, patent (CN216028173U) discloses a positioning drilling device for mechanical castings, which records: "The casting can be positioned by the third electric push rod, which is beneficial to improving the quality of subsequent drilling. The front and rear positions of the casting to be drilled can be conveniently adjusted by the first motor, and the left and right positions of the casting to be drilled can be conveniently adjusted by the second motor; after the casting is positioned by the positioning plates on the left and right sides, then the hand wheel is rotated. The rotation of the hand wheel drives the rotation of the third threaded rod. When the third threaded rod rotates, it drives the lifting block and the clamping block to move downward, and thus the clamping block can re-position the casting, further improving the positioning effect of the casting", and also records: "Due to the unfixed position of the casting, the deviation of the drilling position is caused, which affects the product quality of the casting. At the same time, when drilling the casting at multiple positions, it is necessary to repeatedly adjust the position of the casting for drilling. However, this not only reduces the work efficiency, but also easily damages the external structure of the casting when repeatedly fixing and adjusting the casting."

[0004] In summary, it can be seen that the following technical problems exist in the prior art: when drilling a casting, waste chips will fly, which causes inconvenience to the collection and cleaning of waste chips. When cleaning waste chips, it is necessary to stop the machine, affecting the production efficiency. For this reason, the present application proposes a positioning drilling device for mechanical castings, and provides a new technical solution to solve the above-mentioned technical problems. Summary of the Invention

[0005] Based on this, in view of the above technical problems, it is necessary to provide a positioning drilling device for mechanical castings.

At the same time, when the two adjustment sliders rotate synchronously, they can drive the connecting frame to rotate inside the waste chip tray with the positioning column as the axis. When the connecting frame rotates, the cleaning member on the side of the connecting frame can contact the waste chips, thereby pushing the waste chips to move inside the waste chip tray until the waste chips reach the position of the chip discharge through groove, and then the waste chips fall downward to achieve the discharge of waste chips.

[0022] To solve this technical problem, the present invention provides a positioning drilling device for mechanical castings, which is applied to the positioning drilling of castings.

[0023] Specifically, please refer to Figure 1 - Figure 6 , the positioning drilling device for mechanical castings specifically includes: A fixed frame 1, and a drilling mechanism 2 is arranged in the middle of the upper end of the fixed frame 1 for drilling; An adjusting component 3 is arranged at the lower part inside the fixed frame 1, a scrap tray 4 for collecting chips is arranged above the adjusting component 3, and fixed fixtures 5 for fixing the casting are arranged on both sides inside the scrap tray 4; The adjusting component 3 includes two longitudinal linear motors 6.

[0025] In order to enable the personnel in the technical field to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings.

[0026] Embodiment 1: Please refer to Figure 1 - Figure 10 , a mechanical casting positioning drilling device, which includes: A fixed frame body 1, and a drilling mechanism 2 for drilling is arranged in the middle of the upper end of the fixed frame body 1; An adjusting assembly 3 is arranged at the lower part inside the fixed frame body 1. Above the adjusting assembly 3, there is a waste chip tray 4 for collecting waste chips. Fixed jigs 5 for fixing the casting are arranged on both sides inside the waste chip tray 4; it can be seen that the waste chip tray 4 can be driven to move in four directions through the adjusting assembly 3. Thus, during the movement of the waste chip tray 4, the casting fixed by the fixed jig 5 can be adjusted, so as to realize the adjustment of the drilling position.

[0027] Specifically, the adjusting component 3 includes two longitudinal linear motors 6. The upper ends of the two longitudinal linear motors 6 are both movably connected to longitudinal moving seats 7. The two longitudinal linear motors 6 are connected by a connecting shaft. The two longitudinal linear motors 6 are driven by the same motor. Above the two longitudinal linear motors 6, there is a transverse linear motor 8. The transverse linear motor 8 is arranged at a ninety-degree intersection with the longitudinal linear motors 6. The two ends of the transverse linear motor 8 are respectively fixedly connected to the longitudinal moving seats 7 on the two longitudinal linear motors 6. A transverse moving seat 9 is movably connected to the transverse linear motor 8. It can be seen that the two longitudinal linear motors 6 can drive the two longitudinal moving seats 7 to move synchronously, thereby driving the transverse linear motor 8 and the transverse moving seat 9, the waste chip tray 4, and the fixed fixture 5 above the transverse linear motor 8 to perform longitudinal two-way adjustment. The transverse linear motor 8 can drive the transverse moving seat 9 and the waste chip tray 4 and the fixed fixture 5 above the transverse moving seat 9 to perform transverse two-way adjustment, thereby achieving a four-way adjustment effect.

[0028] The lower end of the waste chip tray 4 is fixedly connected to the transverse moving seat 9. An annular slide rail 12 is fixedly connected to the inner side of the waste chip tray 4. Two adjusting slide seats 13 are arranged inside the annular slide rail 12. The two adjusting slide seats 13 are symmetrically arranged. The two adjusting slide seats 13 are both slidably connected to the annular slide rail 12. A positioning column 14 is fixedly connected to the middle of the waste chip tray 4. The lower ends of the two adjusting slide seats 13 are fixedly connected by a connecting frame 15. The middle of the connecting frame 15 is sleeved outside the positioning column 14. The connecting frame 15 is rotatably connected to the positioning column 14. Among them, in order to avoid waste chip accumulation at the top of the positioning column 14, the top of the positioning column 14 is arc-shaped. Cleaning members 16 are arranged on both sides of the connecting frame 15. A chip discharge through groove 17 is formed in the waste chip tray 4. The two fixed fixtures 5 are respectively fixed on one side of the two adjusting slide seats 13 close to each other.

[0029] It can be seen that the waste chip tray 4 can collect the waste chips generated during drilling. By rotating the two adjusting slide seats 13 synchronously clockwise or synchronously counterclockwise, the rotation adjustment of the casting can be realized, thereby further improving the flexibility of the drilling position adjustment. At the same time, when the two adjusting slide seats 13 rotate synchronously, the connecting frame 15 can be driven to rotate inside the waste chip tray 4 with the positioning column 14 as the axis. When the connecting frame 15 rotates, the cleaning member 16 on the side of the connecting frame 15 can contact the waste chips, thereby pushing the waste chips to move inside the waste chip tray 4 until the waste chips reach the position of the chip discharge through groove 17, and then the waste chips fall downward to achieve the discharge of the waste chips. Furthermore, the waste chips can be cleaned without stopping the device during operation.

[0030] Further, in order to better support and fix the waste chip tray 4, a mounting seat 10 is fixedly connected to the lower end of the waste chip tray 4. The mounting seat 10 is detachably and fixedly connected to the transverse moving seat 9. Stable lifting frames 11 are arranged on both sides of the mounting seat 10. The ends of the stable lifting frames 11 are fixedly connected to the mounting seat 10. The upper end of the mounting seat 10 is fixedly connected to the waste chip tray 4. The number of stable lifting frames 11 on both sides of the mounting seat 10 is multiple.

[0031] Further, in order to facilitate the centralized collection of waste chips, a chip discharge chute 28 is fixedly connected to the lower end of the waste chip tray 4 at a position corresponding to the chip discharge through groove 17. The upper end of the chip discharge chute 28 is communicated with the chip discharge through groove 17. The lower part of the chip discharge chute 28 is inclined. The end of the lower end of the chip discharge chute 28 is fixedly connected with a chip discharge connection port 29. The chip discharge connection port 29 is communicated with the inside of the chip discharge chute 28. The waste chips discharged from the chip discharge through groove 17 fall into the inside of the chip discharge chute 28. By connecting an external suction device to the chip discharge connection port 29, the waste chips in the chip discharge chute 28 can be sucked out, achieving the cleaning effect of the waste chips.

[0032] Embodiment 2: The mechanical casting positioning drilling device provided in Embodiment 1 is further optimized. Specifically, as Figure 9 shown, the cleaning member 16 includes a cleaning plate 26. A flexible contact strip 27 is fixedly connected to the lower end of the cleaning plate 26. The cleaning plate 26 is fixedly connected to the side surface of the connecting frame 15. One end of the cleaning plate 26 away from the center of the waste chip tray 4 is arranged in an arc-shaped curved surface, and one end of the cleaning plate 26 close to the center of the waste chip tray 4 is arranged in an inclined surface. Among them, the cleaning plate 26 is made of metal, and the flexible contact strip 27 is made of rubber.

[0033] Through the above structural design, the cleaning plate 26 can drive the flexible contact strip 27 to move synchronously. Through the arc-shaped curved surface setting and inclined surface setting at the end of the cleaning plate 26, when the cleaning plate 26 rotates, it can better guide the waste chips, making the waste chips gather in the direction of the chip discharge through groove 17, thereby facilitating the discharge of the waste chips more conveniently.

[0034] Embodiment 3: The mechanical casting positioning drilling device provided in Embodiment 1 is further optimized. Specifically, as Figure 7 - Figure 8 shown, guide wheel grooves 18 are formed on both the upper and lower end surfaces of the annular slide rail 12. A limit chute 19 is formed on the inner side surface of the annular slide rail 12. A fixed internal gear 20 is arranged inside the limit chute 19.

[0035] Specifically, the adjusting slider 13 includes a slider body 21. Guide rollers 22 are rotatably connected to the four corner positions on the side of the slider body 21 close to the annular slide rail 12. The two guide rollers 22 on the upper part of the slider body 21 are in rolling connection with the guide wheel groove 18 at the upper end of the annular slide rail 12, and the two guide rollers 22 on the lower part of the slider body 21 are in rolling connection with the guide wheel groove 18 at the lower end of the annular slide rail 12. A limit slider 23 is provided in the middle of the side of the slider body 21 close to the annular slide rail 12, and the limit slider 23 is in sliding connection with the limit chute 19. A driving wheel 24 is rotatably connected to the middle of the slider body 21, and the driving wheel 24 is in meshing connection with the fixed internal teeth 20. A synchronous motor 25 is fixedly connected to the top of the slider body 21. The output end of the synchronous motor 25 extends into the slider body 21, and the output end of the synchronous motor 25 is fixedly connected to the driving wheel 24.

[0036] Through the above structural design, by synchronously starting the two synchronous motors 25, the two driving wheels 24 rotate synchronously. Through the meshing connection between the driving wheel 24 and the fixed internal teeth 20, the slider body 21 can be driven to drive the fixed fixture 5 to move along the track of the annular slide rail 12 inside the waste chip tray 4, thereby achieving the effect of rotating and adjusting the casting.
