[0016] (1) The bar is placed on the surface of the storage plate. Under the action of gravity, the bar slides to the surface of the crossbeam. The first hydraulic cylinder drives the transmission plate to move upward. The transmission plate drives the crossbeam to move upward through the support leg. The crossbeam pushes the bar on the surface into the surface of the ramp plate. The bar automatically slides to the center position of the V-block. The third hydraulic cylinder drives the lifting frame to move downward through the transmission frame. The lifting frame drives the pressure block to move downward.

[0017] (2) The second hydraulic cylinder drives the linkage plate to move, and the linkage plate drives the top material inclined block to move. Since the top material inclined block is an inclined structure, the top material inclined block pushes the bar material at the top of the V-shaped block into the surface of the discharge table, and discharges it from the discharge table. This realizes that the automatic drilling center hole device can automatically push the bar material out, which facilitates the automatic entry and exit of the bar material, reduces the participation of manual labor, reduces the intensity of manual labor, and improves the efficiency of bar material drilling.

[0018] (3) The threaded rod is driven to rotate by a servo motor. Under the threaded connection between the threaded rod and the threaded block, the threaded block is driven to move laterally. The threaded block drives the pressure block to move laterally, so that the pressure block can clamp and fix bars of different lengths. This realizes convenient lateral adjustment and movement of the automatic center hole drilling device when clamping bars, which facilitates clamping and fixing bars of different lengths.

[0029] Please see Figure 1-8This utility model provides an embodiment of an automatic center hole drilling device for bar stock, comprising a frame 1 and a feeding rack 2. The feeding rack 2 is disposed on the outside of the frame 1, and a storage plate 3 is installed on the top of the feeding rack 2. A support platform 8 is installed on the top of the frame 1, and multiple sets of V-shaped blocks 11 with equal spacing are installed on the top of the support platform 8. A discharge platform 12 is disposed on the top of the support platform 8 on one side of the V-shaped blocks 11, and a discharge rack 13 is symmetrically installed on the bottom of the discharge platform 12. The discharge platform 12 is connected to the support platform 8 through the discharge rack 13. A ramp plate 10 is disposed on the top of the support platform 8 on the other side of the V-shaped blocks 11. A positioning seat 9 is symmetrically installed at the bottom end of the ramp plate 10, and the ramp plate 10 is connected to the support platform 8 through the positioning seat 9. A first hydraulic cylinder 4 is installed at the top of the frame 1 on one side of the support platform 8. A transmission plate 5 is installed at the top of the first hydraulic cylinder 4. A crossbeam 7 is set at the top of the transmission plate 5. Support legs 6 are symmetrically installed at the bottom end of the crossbeam 7, and the support legs 6 are connected to the transmission plate 5. A linkage plate 16 is installed inside the support platform 8 below the V-block 11. A top material inclined block 17 is installed at the top of the support platform 8 on one side of the V-block 11. A drilling machine 18 is installed on the side of the top of the frame 1 away from the support platform 8.

[0030] The bar stock is placed on the surface of the storage plate 3. Under the action of gravity, the bar stock slides down to the surface of the crossbeam 7. The first hydraulic cylinder 4 drives the transmission plate 5 to move upward. The transmission plate 5 drives the crossbeam 7 to move upward via the support leg 6. The crossbeam 7 pushes the bar stock on the surface into the surface of the ramp plate 10. With the support of the positioning seat 9 on the ramp plate 10, the bar stock automatically slides down to the center position of the V-block 11 because the ramp plate 10 is a ramp structure. The lifting drive of the crossbeam 7 facilitates the separation of the front and rear groups of bar stock to facilitate the flow of one group of bar stock at a time. With the support of the support frame 19 on the third hydraulic cylinder 25, the third hydraulic cylinder 25 passes through... The transmission frame 26 drives the lifting frame 23 to move downwards, the lifting frame 23 drives the pressure block 27 to move downwards, the lifting frame 23 drives the limiting block 20 to slide on the surface of the slide rail 21 for limiting support, the pressure block 27 presses and fixes the bar on the surface of the V-block 11, and the drilling machine 18 performs drilling. Since the V-block 11 adopts a V-shaped structure, it can easily adapt to the center positioning of bars of different diameters, realizing the automatic feeding center positioning drilling of bars by the automatic center drilling device, which facilitates the center positioning drilling of bars of different diameters and increases the drilling range of bars of different diameters by the automatic center drilling device.

[0031] A positioning frame 14 is installed at the top of the frame 1 below the linkage plate 16. A second hydraulic cylinder 15 is installed on the side wall of the positioning frame 14, and the output end of the second hydraulic cylinder 15 is connected to the linkage plate 16.

[0032] After drilling is completed, the third hydraulic cylinder 25 drives the pressure block 27 to reset. Under the support of the support platform 8 and the support of the positioning frame 14 on the second hydraulic cylinder 15, the second hydraulic cylinder 15 drives the linkage plate 16 to move, and the linkage plate 16 drives the top material inclined block 17 to move. Since the top material inclined block 17 is an inclined structure, the top material inclined block 17 pushes the bar material at the top of the V-shaped block 11 into the surface of the discharge platform 12, and discharges it from the discharge platform 12. This realizes the automatic top material discharge of the bar material by the automatic drilling center hole device, which facilitates the automatic entry and exit of the bar material, reduces manual intervention, reduces the intensity of manual labor, and improves the efficiency of bar material drilling.

[0033] A support frame 19 is installed at the top of the support platform 8 above the V-block 11. A lifting frame 23 is slidably installed inside the support frame 19. A third hydraulic cylinder 25 is installed on the outer wall of the support frame 19 on one side of the lifting frame 23.

[0034] The output end of the third hydraulic cylinder 25 is equipped with a transmission frame 26, and the transmission frame 26 is connected to the lifting frame 23. The lifting frame 23 is equipped with a threaded rod 22, and a threaded block 24 is fitted on the surface of the threaded rod 22. The threaded block 24 is slidably connected to the lifting frame 23, and a pressure block 27 is installed at the bottom end of the threaded block 24.

[0035] A servo motor 28 is installed inside the lifting frame 23 on one side of the threaded rod 22, and the output end of the servo motor 28 is connected to the threaded rod 22. A limit block 20 is movably installed at the end of the threaded rod 22 away from the servo motor 28, and the limit block 20 is fixedly connected to the lifting frame 23.

[0036] A slide rail 21 is installed on the inner wall of the support frame 19 on one side of the limiting block 20, and the slide rail 21 is slidably connected to the limiting block 20.

[0037] The threaded rod 22 is opened by the servo motor 28. With the support of the lifting frame 23, the servo motor 28 drives the threaded rod 22 to rotate. Under the threaded connection between the threaded rod 22 and the threaded block 24, the threaded block 24 is driven to move laterally. The threaded block 24 drives the pressure block 27 to move laterally, so that the pressure block 27 can clamp and fix bars of different lengths. This realizes convenient lateral adjustment and movement when the automatic center hole drilling device clamps bars, which is convenient for clamping and fixing bars of different lengths.

[0038] In this embodiment, when in use: An external power supply is connected. First, the bar stock is placed on the surface of the storage plate 3. Under gravity, the bar stock slides down to the surface of the crossbeam 7. The first hydraulic cylinder 4 drives the transmission plate 5 to move upwards. The transmission plate 5, via the support leg 6, drives the crossbeam 7 to move upwards. The crossbeam 7 pushes the bar stock onto the surface of the ramp plate 10. The bar stock automatically slides down to the center position of the V-block 11. The lifting drive of the crossbeam 7 facilitates the separation of the two sets of bar stock, allowing one set of bar stock to flow in at a time. The third hydraulic cylinder 25, via the transmission frame 26, drives the lifting frame 23 to move downwards. The lifting frame 23 drives the pressure block 27 to move downwards. The pressure block 27 presses against the V-block 11. The bar stock on the surface is clamped and fixed, and then drilled by the drilling machine 18. The second hydraulic cylinder 15 drives the linkage plate 16 to move, and the linkage plate 16 drives the top material inclined block 17 to move. Since the top material inclined block 17 is an inclined structure, the top material inclined block 17 pushes the bar stock at the top of the V-block 11 into the surface of the discharge table 12, and discharges it from the discharge table 12. The servo motor 28 drives the threaded rod 22 to rotate, and drives the threaded block 24 to move laterally under the threaded connection between the threaded rod 22 and the threaded block 24. The threaded block 24 drives the pressure block 27 to move laterally, so that the pressure block 27 can clamp and fix bar stock of different lengths to complete the use of the automatic center hole drilling device.
