Description

Technical Field

[0001] This utility model relates to the technical field of brake disc processing equipment, and in particular to a linkage drilling and tapping machine tool. Background Technology

[0002] In the automotive manufacturing industry, brake discs are critical safety components, and their machining accuracy and quality directly affect driving safety. Traditional brake disc machining processes are complex, typically requiring multiple machine tools of different types to perform drilling, tapping, turning, vertical milling, and side milling. This not only leads to low production efficiency but also introduces positioning errors between processes, affecting the overall machining accuracy of the brake disc. Furthermore, the investment in multiple machines significantly increases production costs, including equipment procurement, installation, commissioning, and subsequent maintenance. Moreover, the need for multiple clamping operations during different machine operations can reduce product consistency due to operational errors during clamping. Therefore, developing a multi-functional drilling and tapping machine tool that integrates drilling, tapping, turning, vertical milling, and side milling is of significant practical importance, as it can improve the machining efficiency and accuracy of brake discs while reducing production costs.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0028] like Figures 1-10 As shown, a linkage drilling and tapping machine tool includes a bed 1, a column 2, a base 7, a receiving mechanism 8, and a drilling and tapping mechanism 6. The receiving mechanism 8 is provided on the upper part of the bed 1, and the base 7 is provided on one side of the receiving mechanism 8. The drilling and tapping mechanism 6 is provided on the base 7. The drilling and tapping mechanism 6 includes a lifting platform 601, a turret support 603, a first drive motor 602, and a second drive motor 607. The lifting platform 601 is slidably connected to the first sliding groove on the inner wall of the base 7 through first sliding strips on both sides. The turret support 603 is provided at one end of the lifting platform 601. The turret support 603 is provided with a plurality of connecting holes 604 and cutting tools 606. The other end of the turret support 603 is connected to the first drive motor 602 through a first rotating shaft. The second drive motor 607 is provided on the upper part of the base 7 and is connected to the first lead screw 605 through a coupling. The first lead screw 605 is connected to the screw hole on the lifting platform 601 to form a transmission structure.

[0029] It should be noted that, in order to achieve integrated machining of brake disc drilling, tapping, turning, vertical milling, and side milling, a receiving mechanism 8 and a drilling and tapping mechanism 6 for fixing and rotating the brake disc are set on the machine bed. These mechanisms can process the brake disc. Different machining methods require different tools. Traditional machining methods generally use multiple machines working together or require operators to change tools in conjunction with the control system. This method has significant drawbacks. Machining a single brake disc requires different machines, so the brake disc needs to be installed multiple times. Moreover, changing tools is cumbersome and greatly affects work efficiency. Based on this, a centralized drilling and tapping machine was designed, which can greatly overcome this problem.

[0030] It should be further explained that during operation, the drilling and tapping mechanism 6 can achieve precise adjustment in the left and right directions with the help of the second drive mechanism 4, thereby achieving adjustment of the horizontal position of the entire drilling and tapping mechanism 6. At the same time, through the first drive mechanism 5, the drilling and tapping mechanism 6 can be flexibly adjusted in the front and back directions, thereby achieving change in the horizontal longitudinal position of the entire drilling and tapping mechanism 6. Under the precise control of the control system, the drilling and tapping mechanism 6 can carry out efficient and precise machining operations on the brake disc.

[0031] As shown in the figure - Figure 7 As shown, the receiving mechanism 8 includes a first rotating shaft 801, a rotating table 802, a three-grip chuck 803, a third drive motor 806, a first synchronous pulley 805, and a second synchronous pulley 804. The first rotating shaft 801 is installed in the connecting hole of the bed 1, and the rotating table 802 and the three-grip chuck 803 are installed on the upper part of the first rotating shaft 801. The lower part of the first rotating shaft 801 is connected to the first synchronous pulley 805 on the third drive motor 806 through the second synchronous pulley 804 and the synchronous belt.

[0032] It should be noted that the receiving mechanism 8 is set up to fix the brake disc and rotate it, so as to cooperate with the drilling and tapping mechanism 6 to complete the processing of it. The first rotating shaft 801 is equipped with a rotating table 802 and a three-jaw chuck 803 on its upper part. The first rotating shaft 801 is connected to the third drive motor 806 through the second synchronous pulley 804 and the synchronous belt to realize power transmission. The entire rotating table 802 can rotate. The three-jaw chuck 803 is a starting chuck that can fix and limit the brake disc and drive the brake disc to rotate at the same time.

[0033] like Figures 1-10As shown, the base 7 is mounted on the first drive mechanism 5. The first drive mechanism 5 includes a first receiving plate 501, a second lead screw 504, a fourth drive motor 503, and a first receiving slider 505. The bottom of the first receiving plate 501 is connected to the second slide bar 502 and the second lead screw 504 on the second drive mechanism 4 through the first receiving slider 505 and the first nut, respectively. The second lead screw 504 is mounted on the second receiving plate 404 through a bearing seat, and one end of the second lead screw 504 is connected to the fourth drive motor 503 through a coupling.

[0034] It should be noted that the first receiving plate 501 can move back and forth by rotating the second lead screw 504 at the bottom, which in turn drives the upper drilling and tapping mechanism 6 to move back and forth as well.

[0035] like Figures 1-7 As shown, the second drive mechanism 4 includes a second receiving plate 404, a third lead screw 402, a fifth drive motor 401, a third slide bar 403, and a second receiving slider 405. The second receiving plate 404 is connected to the third slide bar 403 and the third lead screw 402 on the bed 1 through the second receiving slider 405 at the bottom and the second nut, respectively. The third lead screw 402 is mounted on the upper part of the bed 1 through a bearing seat, and the third lead screw 402 is connected to the output shaft of the fifth drive motor 401 through a coupling.

[0036] It should be noted that the second receiving plate 404 can move left and right under the transmission of the third lead screw 402, and in conjunction with the control system, it can transmit the upper first drive mechanism 5 and drilling mechanism 6 left and right, so that the tool 606 on the turret support 603 can approach the brake disc, thereby realizing machining.

[0037] like Figures 1-8 As shown, it also includes a feeding mechanism 3, which includes a transverse connecting rod 301, a first connecting support 302, a first pneumatic cylinder 303, a second connecting support 305, a second pneumatic cylinder 306, and a parallel opening and closing pneumatic gripper 308. The transverse connecting rod 301 is connected to the base 7 through the column 2 to form a support frame structure, and a second connecting support 305 is provided on the transverse connecting rod 301. The second connecting support 305 is slidably connected to the fourth sliding strip 304 on the transverse connecting rod 301 through a fourth sliding groove on one side, and the second connecting support 305 is connected to the first connecting support 302 through the first pneumatic cylinder 303. The lower part of the second connecting support 305 is connected to the parallel opening and closing pneumatic gripper 308 through the second pneumatic cylinder 306, and a third connecting support 307 is directly provided between the second pneumatic cylinder 306 and the parallel opening and closing pneumatic gripper 308.

[0038] It should be noted that, in order to achieve automated feeding, we designed an independent feeding mechanism 3, which can drive the second connecting support 305 to move laterally through the first pneumatic cylinder 303. Furthermore, a second pneumatic cylinder 306 and a parallel opening and closing air gripper 308 are set on the upper part of the second connecting support 305. The parallel opening and closing air gripper 308 is extended by the second pneumatic cylinder 306, and then the brake disc is grasped by the parallel opening and closing air gripper 308 and moved onto the three-grip chuck 803, thereby realizing automated feeding and automated unloading.

[0039] It should be further explained that a sensor is installed on the transverse connecting rod 301 and a limit switch is installed on the second connecting support 305. Under the control of the control system, the switch can start and stop after reaching the required position, which facilitates control.

[0040] like Figure 1 and Figure 10 As shown, the upper part of the bed 1 is provided with several connecting grooves and connecting holes, and the bed 1 is provided with several guide grooves 9, which are connected to the discharge port 10 on the side wall of the bed 1.

[0041] It should be noted that the guide channel 9 is designed to discharge iron filings and wires generated during the processing. Moreover, the guide channel 9 is connected to the discharge port 10 on the side wall of the bed 1, so that the generated iron filings and wires can be discharged from the discharge port 10. Compared with the traditional manual cleaning method, the cleaning efficiency is greatly improved.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
