[0023] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:
[0024] Embodiment 1: Refer to Figures 1-9 , an automatic drilling device, including a drilling machine 1 and an automatic fixture 2.
[0025] Among them, the automatic fixture 2 includes a fixture base 2-1, a loading chute 2-2, a discharging chute 2-3, a turntable 2-4, a first driving cylinder 2-5, and a second driving cylinder 2-6.
[0026] Specifically, the drilling machine 1 is a numerically controlled drilling machine, which belongs to the prior art and will not be elaborated herein.
[0027] Refer to Figures 1-4 , two side baffles 2-7 are fixedly arranged at intervals on the fixture base 2-1; the turntable 2-4 is rotatably arranged on the fixture base 2-1 and is located between the two side baffles 2-7. Specifically, the center of the turntable 2-4 is rotationally matched with the fixture base 2-1; the gap between the two side baffles 2-7 matches the axial length of the workpiece; a V-shaped groove 2-41 is provided on the top side of the turntable 2-4; when the workpiece is in the V-shaped groove 2-41, the two ends of the workpiece are close to or just in contact with the two side baffles 2-7; the first driving cylinder 2-5 is used to drive the turntable 2-4 to rotate reciprocally.
[0028] Refer to Figures 1-4 , among which, the loading chute 2-2 and the discharging chute 2-3 are both fixedly arranged obliquely and are distributed vertically; the low end of the loading chute 2-2 is close to the turntable 2-4; the high end of the discharging chute 2-3 is close to the turntable 2-4. Specifically, the cross sections of the loading chute 2-2 and the discharging chute 2-3 are both U-shaped.
[0029] In this embodiment, refer to Figures 1-4 , the first driving cylinder 2-5 is a telescopic cylinder; the tail of the first driving cylinder 2-5 is hinged to the fixture base 2-1 through a first rotating shaft 5-21; the output end of the first driving cylinder 2-5 is hinged to the lower part of the turntable 2-4 through a second rotating shaft 5-22. Refer to Figure 7 , when the output end of the first driving cylinder 2-5 retracts, the first driving cylinder 2-5 will drive the turntable 2-4 to rotate clockwise by a certain angle (such as 30°) to the discharging position. At this time, the V-shaped groove 2-41 of the turntable 2-4 is connected to the high end of the discharging chute 2-3, and the workpiece N in the V-shaped groove 2-41 of the turntable 2-4 will automatically roll into the high end of the discharging chute 2-3 for automatic discharging (refer to Figure 7)。When the output end of the first driving cylinder 2-5 extends outward, the first driving cylinder 2-5 will drive the turntable 2-4 to rotate counterclockwise by a certain angle (such as 30°) to reach the feeding position (i.e., the initial position). At this time, the V-shaped groove 2-41 of the turntable 2-4 is at the highest position, and the V-shaped groove 2-41 of the turntable 2-4 is connected to the lower end of the feeding groove 2-2. A workpiece N at the lowest position in the feeding groove 2-2 will automatically roll into the V-shaped groove 2-41 of the turntable 2-4 for automatic feeding (see Figure 8 ).
[0030] See Figures 1-4 . In this embodiment, the second driving cylinder 2-6 also adopts a telescopic cylinder; the second driving cylinder 2-6 is fixedly installed on one of the side baffles 2-7, and the output end of the second driving cylinder 2-6 vertically faces the other side baffle 2-7. When a workpiece N at the lowest position in the feeding groove 2-2 automatically rolls into the V-shaped groove 2-41 of the turntable 2-4, then start the output end of the second driving cylinder 2-6 to move towards the other side baffle 2-7. The output end of the second driving cylinder 2-6 will axially press the workpiece in the V-shaped groove 2-41 of the turntable 2-4. At this time, both ends of the workpiece N are axially positioned and clamped by the other side baffle 2-7 and the output end of the second driving cylinder 2-6 (see Figures 1-2 ), thereby ensuring the drilling position accuracy.
[0031] See Figures 1-4 . The V-shaped groove 2-41 can center-position the shaft-shaped workpiece N. At this time, the workpiece N is center-positioned and axially pressed (see Figures 1-2 ).
[0032] Before processing in this embodiment, a number of workpieces N to be processed (such as transmission shafts or other pipe-shaped, shaft-shaped, rod-shaped parts) need to be pre-placed on the feeding groove 2-2. Since the feeding groove 2-2 is inclined, each workpiece N in the feeding groove 2-2 will automatically move towards the lower end under its own gravity (see Figures 5-6 ).
[0033] Initially, the V-shaped groove 2-41 of the turntable 2-4 is in the feeding position. A workpiece N at the lowest position in the feeding groove 2-2 (due to the inclined setting) will automatically roll into the V-shaped groove 2-41 of the turntable 2-4 for feeding (see Figures 5-6 ), and then start the second driving cylinder 2-6 to work and axially press the workpiece N located in the V-shaped groove 2-41 (see Figures 1-2), at this time, the workpiece N on the turntable 2-4 is positioned and clamped; then the drilling machine 1 is started to work and feeds downward to drill the workpiece N until the machining is completed and then retracts the tool and resets (since the working principle of the drilling machine belongs to the prior art, it will not be elaborated); then the first driving cylinder 2-5 is started to work to drive the turntable 2-4 to rotate to the blanking position, and the machined workpiece N in the V-shaped groove 2-41 on the turntable 2-4 will roll into the upper end of the blanking groove 2-3 to achieve blanking (see Figure 7 ), and then the workpiece N rolls down obliquely in the blanking groove 2-3 to automatically complete the discharging; then the first driving cylinder 2-5 is started to work and drive the turntable 2-4 to rotate back to the loading position (i.e., the initial position, see Figure 8 ), and then the above work is cycled.
[0034] This embodiment can realize that the workpiece N is automatically loaded from the lower end of the loading groove 2-2 into the V-shaped groove 2-41 of the turntable 2-4, and then the second driving cylinder 2-6 automatically positions and compresses the workpiece N to be machined, and then the drilling machine 1 is started to complete the automatic drilling N-1 machining of the workpiece N (see Figure 2 ), and then the first driving cylinder 2-5 is started to drive the turntable 2-4 to rotate, and the machined workpiece N in its V-shaped groove 2-41 is automatically blanked into the upper end of the blanking groove 2-3 to complete the fully automatic drilling machining of the workpiece.
[0035] Therefore, the utility model can realize the automatic loading, positioning and clamping, and blanking of the workpiece, can perform fully automatic continuous drilling machining, and can greatly improve the production efficiency.
[0036] Embodiment 2: This embodiment is a further improvement on the basis of Embodiment 1:
[0037] See Figure 2 and Figure 5 , in addition, the automatic fixture 2 further includes a stop block 2-8; the stop block 2-8 is fixed on the fixture base 2-1, and a turntable avoiding groove 2-81 is provided on the stop block 2-8; the turntable 2-4 is located in the turntable avoiding groove 2-81.
[0038] During the work, when the workpiece N is automatically loaded from the lower end of the loading groove 2-2 into the V-shaped groove 2-41 of the turntable 2-4, it will be blocked by the stop block 2-8 (see Figure 5 ), which can prevent the problem that the workpiece N rolls too fast when being loaded into the V-shaped groove 2-41 and runs out of the V-shaped groove 2-41 due to inertia, so as to ensure that each workpiece N will stay very stably in the V-shaped groove 2-41 when being automatically loaded from the lower end of the loading groove 2-2 into the V-shaped groove 2-41 of the turntable 2-4.
[0039] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
