Detailed implementation manners
[0025] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.
[0026] A drilling and tapping integrated machine includes: a rotating disk 3, on which a plurality of positioning seats 4 are arranged at intervals in the circumferential direction, and the positioning seats 4 are used to position the workpiece 1 to be processed, and the rotating disk 3 is used to drive the positioning seats 4 to rotate around its axis; a fixing member 5, which is arranged on the rotating disk 3, and each positioning seat 4 corresponds to a fixing member 5, and the fixing member 5 applies a thrust to the workpiece 1 to fix the workpiece 1 to be processed on the positioning seat 4; a plurality of drill bits 6 and a plurality of taps 7 arranged on the side of the rotating disk 3, and the plurality of drill bits 6 and the plurality of taps 7 both have a processing path extending into the positioning seat 4. Among them, the workpiece 1 fixed on the positioning seat 4 can be rotated by the rotating disk 3 driving the positioning seat 4 to the processing paths of the drill bit 6 and the tap 7, so as to perform drilling and tapping operations.
[0027] Based on the above technical solution, an exemplary structure of this solution is as Figures 1 to 3 shown. Among them, four positioning seats 4 are arranged on the rotating disk 3, and these four positioning seats 4 are arranged at equal intervals. Four fixing members 5 are also arranged on the rotating disk 3, and each positioning seat 4 corresponds to a fixing member 5. A workpiece 1 is fixed on each positioning seat 4, and the number of threaded holes 2 to be processed on each workpiece 1 is three, so three drill bits 6 and three taps 7 are each equipped.
[0028] During operation, the workpiece 1 is first placed on the first positioning seat 4 and fixed by the corresponding fixing member 5. Then, the rotating disk 3 rotates to transport the workpiece 1 onto the machining path of the drill bit 6; meanwhile, the second positioning seat 4 is rotated to the position where the workpiece 1 was previously placed. When the rotating disk 3 reaches the designated position, the second workpiece 1 is placed and fixed on the second positioning seat 4. Subsequently, three drill bits 6 simultaneously machine the bottom hole of the first workpiece 1. After the bottom hole of the first workpiece 1 is machined, the rotating disk 3 rotates again to rotate the third positioning seat 4 to the initial position of the first positioning seat 4 for placing the third workpiece 1; meanwhile, the second workpiece 1 is moved onto the machining path of the drill bit 6 for machining the bottom hole. After the bottom hole of the second workpiece 1 is machined, the rotating disk 3 continues to rotate to send the first workpiece 1 that has completed the bottom hole machining onto the machining path of the tap 7 and rotate the fourth positioning seat 4 to the initial position of the first positioning seat 4. At this time, the first workpiece 1 that has completed the bottom hole machining will complete the machining of the threaded hole 2 under the action of the tap 7. Meanwhile, the second and third workpieces 1 also complete the machining of the bottom hole. Under the continuous rotation of the rotating disk 3, all the workpieces 1 in this batch will repeat the above machining steps until all the workpieces 1 in this batch are completely machined.
[0029] In this solution, by arranging a number of positioning seats 4 for fixing the workpiece 1 on the rotating disk 3, and a plurality of drill bits 6 and taps 7 movably arranged on the side of the rotating disk 3, the rotating disk 3 drives the positioning seat 4 to rotate, thereby transporting the workpiece 1 onto the machining paths of the drill bit 6 and the tap 7, and successively completing the drilling and tapping operations of the workpiece 1. Moreover, these operations are all completed at the same station, reducing the number of transfers of the workpiece 1 and lowering the manufacturing cost of the workpiece 1. In addition, in this solution, the workpiece 1 only needs to be fixed once during the drilling and tapping processes, and its machining reference remains unchanged, which also ensures the machining accuracy of the workpiece 1.
[0030] The thrust of the fixing member 5 on the workpiece 1 is along the radial direction of the rotating disk 3 and points from the center of the rotating disk 3 to the edge of the rotating disk 3. This is used to reasonably design the position of the fixing member 5 on the rotating disk 3 so that more positioning seats 4 can be loaded on the rotating disk 3. The more positioning seats 4 there are on the rotating disk 3, the smaller the angle of each rotation of the rotating disk 3, and the faster the positioning seat 4 rotates, thereby increasing the machining efficiency of the workpiece 1.
[0031] The drill bit 6 and the tap 7 are arranged oppositely, and the movement path of the drill bit 6 and the movement path of the tap 7 are on the same straight line.
[0032] In this solution, when there are four positioning seats 4, while the drill bit 6 is machining the third workpiece 1, the tap 7 starts to perform tapping operation on the first workpiece 1. In order to enable the forces exerted by the drill bit 6 and the tap 7 on the rotating disk 3 to cancel each other out, thereby extending the service life of the rotating disk 3, the moving paths of the drill bit 6 and the tap 7 are set on the same straight line.
[0033] The positioning seat 4 has a positioning lug 8 facing the rotation center of the rotating disk 3. When the workpiece 1 is fixed on the positioning seat 4, the positioning lug 8 is embedded into the workpiece 1 to provide a limit for the workpiece 1, so as to prevent the forces exerted by the drill bit 6 and the tap 7 on the workpiece 1 from causing the workpiece 1 to have a lateral offset on the positioning seat 4, thereby further ensuring the machining quality of the workpiece 1.
[0034] A plurality of through holes 9 corresponding to the holes to be machined on the workpiece 1 one by one are provided on the positioning seat 4. The through holes 9 are used for the drill bit 6 and the tap 7 to pass through, and play a guiding role for the drill bit 6 and the tap 7.
[0035] Furthermore, the fixing member 5 includes: a fixing frame 10 which is fixedly connected to the rotating disk 3 and is arranged opposite to the positioning seat 4; a first driving member 11 which is connected to the fixing frame 10 and the output end of the first driving member 11 faces the positioning seat 4; a pressing block 12 which is connected to the output end of the first driving member 11 and is used for pressing on the workpiece 1.
[0036] The fixing frame 10 is used for the installation and fixation of the entire fixing member 5 on the rotating disk 3. Among them, the fixing frame 10 and the rotating disk 3 are in threaded connection. The first driving member 11 is preferably a cylinder. The pressing block 12 is pressed on the workpiece 1 by the thrust of the cylinder, so that the workpiece 1 can be fixed on the positioning seat 4.
[0037] Preferably, the pressing block 12 is a nylon block, so as to prevent the workpiece 1 from being knocked when the first driving member 11 presses on the workpiece 1 through the pressing block 12.
[0038] Furthermore, this solution further includes: a support frame 13. A second driving member 14 for driving the rotating disk 3 to rotate is arranged on the support frame 13. The rotating disk 3 is connected to the output end of the second driving member 14; several third driving members 15 which are connected to the support frame 13 and are located on the side of the rotating disk 3. The third driving members 15 are used for driving the drill bit 6 and the tap 7 to move on the side of the rotating disk 3.
[0039] The second driving member 14 and the third driving member 15 are preferably motors. The support frame 13 serves as the support of the entire drilling and tapping machine. And, it can also be equipped with accessories such as a spray nozzle water pipe, etc., for providing lubrication for the drill bit 6 and the tap 7 and cooling the workpiece 1 when the workpiece 1 is drilled and tapped.
