An automatic feeding device for twist drill materials Technical Field

[0001] This utility model relates to the technical field of twist drill production equipment, and in particular to an automatic feeding device for twist drill materials. Background Technology

[0002] The twist drill production equipment sector is a collection of specialized equipment and technologies focused on twist drill manufacturing. It covers the entire process from blank processing, cutting and shaping, surface treatment, inspection, and packaging, including equipment such as bar cutting machines, CNC grinding machines, and coating equipment. The equipment must be compatible with materials such as high-speed steel and cemented carbide to meet the precision machining requirements of different drill bit specifications (from micrometers to tens of millimeters). It integrates CNC technology and automated processes, widely serving fields such as machining, aerospace, and electronics manufacturing, with the core objective of efficiently producing high-precision hole-machining tools.

[0003] When producing twist drills, the rods used for making twist drills need to be transported by a rod conveyor. However, existing equipment often uses conveyor belts or similar structures to transport the rods. When the rods are transported, the conveyor belt stops when they reach the designated position. However, the rods have inertia and are prone to slight forward movement, which causes the position of the rods to deviate each time they are transported, greatly affecting the production accuracy.

[0004] Therefore, we propose an automatic feeding device for twist drill materials to solve the above problems. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic feeding device for twist drill material includes a feeding bin, on the inner side of which are provided multiple feeding mechanisms, each of which holds a rod; a conveying platform is fixedly installed on one side of the feeding bin, and a conveying trough is opened on the top of the conveying platform, with a conveying mechanism on the inner side of the conveying trough.

[0007] Specifically, a feeding cylinder is fixedly installed on the bottom inner wall of the feeding hopper to facilitate the stacking of bar stock.

[0008] Specifically, the feeding mechanism includes two fixed shafts, two limiting shafts, and two supporting metal blocks. Two fixed shafts and two limiting shafts are fixedly installed on one inner wall of the feeding bin. Supporting metal blocks are rotatably sleeved on both fixed shafts. Each of the two supporting metal blocks has a limiting protrusion at one end near the limiting shaft and a supporting protrusion at the other end. Both supporting protrusions are in contact with the same bar.

[0009] Specifically, a push cylinder is fixedly installed on the top of the feeding hopper to facilitate pushing the bar material to the conveying platform.

[0010] Specifically, the conveying mechanism includes a servo motor, a ball screw, a slider, a clamping base, and a clamping assembly. A ball screw is rotatably mounted on one inner wall of the conveying trough. A drive trough is provided inside the conveying platform. A servo motor is fixedly mounted on one inner wall of the drive trough. The output shaft of the servo motor is fixedly connected to the ball screw. A slider is threaded onto the ball screw. The slider is slidably mounted on the bottom inner wall of the conveying trough. A clamping base is fixedly mounted on the top of the slider. A clamping assembly is provided on the clamping base.

[0011] Specifically, the clamping assembly includes a guide metal block and a clamping metal block. The guide metal block is fixedly installed on one side of the slider, and a guide groove is provided on one side of the guide metal block. The clamping metal block is slidably installed on the inner side of the guide groove. The clamping metal block contacts the clamping base to clamp the bar.

[0012] Specifically, two threaded rods are rotatably mounted on the top of the clamping base, and a motor slot is provided inside the clamping base. Two synchronous motors are fixedly installed on the bottom inner wall of the motor slot. The output shafts of the two synchronous motors are respectively fixedly connected to the corresponding threaded rods, and the corresponding threaded rods can be driven to rotate by the synchronous motors.

[0013] Specifically, two guide posts are fixedly installed on one side of the clamping metal block. Each guide post has a threaded hole at its top, and two threaded rods are threadedly connected to the corresponding threaded holes, so that the corresponding guide posts can be moved axially by the two threaded rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the conveying mechanism can clamp the bar stock and cooperate with the ball screw to stably and accurately convey the bar stock to the designated position without deviation, which greatly improves the accuracy during production.

[0022] In this embodiment, a feeding cylinder 2 is fixedly installed on the bottom inner wall of the feeding hopper 1 to facilitate the stacking of the bar stock 3.

[0023] In this embodiment, the feeding mechanism includes two fixed shafts 4, two limiting shafts 5, and two supporting metal blocks 6.

Each of the two supporting metal blocks 6 has a limiting protrusion at one end near the limiting shaft 5 and a supporting protrusion at the other end. Both supporting protrusions are in contact with the same rod 3.

[0024] In this embodiment, a push cylinder 7 is fixedly installed on the top of the feeding hopper 1 to facilitate pushing the bar 3 to move onto the conveying platform 8.

[0025] In this embodiment, the conveying mechanism includes a servo motor 9, a ball screw 10, a slider 11, a clamping base 13, and a clamping assembly. The ball screw 10 is rotatably mounted on one inner wall of the conveying trough. A drive trough is provided inside the conveying platform 8. The servo motor 9 is fixedly mounted on one inner wall of the drive trough. The output shaft of the servo motor 9 is fixedly connected to the ball screw 10. The slider 11 is threaded onto the ball screw 10. The slider 11 is slidably mounted on the bottom inner wall of the conveying trough. The clamping base 13 is fixedly mounted on the top of the slider 11. A clamping assembly is provided on the clamping base 13.

[0026] In this embodiment, the clamping assembly includes a guide metal block 12 and a clamping metal block 14. The guide metal block 12 is fixedly installed on one side of the slider 11. A guide groove is provided on one side of the guide metal block 12. The clamping metal block 14 is slidably installed on the inner side of the guide groove. The clamping metal block 14 contacts the clamping base 13, thereby clamping the rod 3.

[0027] In this embodiment, two threaded rods 16 are rotatably mounted on the top of the clamping base 13. A motor slot is provided inside the clamping base 13. Two synchronous motors 17 are fixedly mounted on the bottom inner wall of the motor slot. The output shafts of the two synchronous motors 17 are respectively fixedly connected to the corresponding threaded rods 16, and the corresponding threaded rods 16 can be driven to rotate by the synchronous motors 17.

[0028] In this embodiment, two guide posts 15 are fixedly installed on one side of the clamping metal block 14. The top of each guide post 15 is provided with a threaded hole, and two threaded rods 16 are respectively threaded to the corresponding threaded holes, so as to facilitate the corresponding guide post 15 to move axially by the two threaded rods 16.

[0029] Working principle: When producing twist drills, the rod 3 first needs to be transported to the designated position. The operator feeds the rod 3 into the feeding bin 1 through the feeding port on one side. At this time, the feeding cylinder 2 is activated, causing the bottom rod 3 to rise. As the rod 3 rises, it pushes against the two corresponding support metal blocks 6, causing them to rotate around the corresponding fixed axis 4. One end of the support metal block 6 has a limiting protrusion. At this time, the limiting protrusion moves away from the limiting axis 5, and the support metal block... The other end of 6 is provided with a support protrusion. When the support protrusion is raised, and the bar 3 rises to a certain height and passes over the support protrusion of the upper set of support metal blocks 6, the support metal blocks 6 that were originally lifted are reset under the action of gravity, and the support protrusion returns to a horizontal state. At this time, the bottom bar 3 is supported by the upper set of support metal blocks 6. This process is repeated to complete one layer of stacking. The feeding cylinder 2 is reset, and the next bar 3 stacking cycle begins. When the top bar 3 rises to the designated position, the cylinder 7 is activated to move it. The bar 3 is pushed by the cylinder 7, causing one end to pass through the clamping base 13. At this time, the two synchronous motors 17 start and drive the corresponding threaded rods 16 to rotate. The two guide posts 15 are threaded, and the two threaded rods 16 are threaded to the corresponding threaded holes. The two guide posts 15 are slidably engaged with the guide grooves of the guide metal block 12 and can only move axially. When the two threaded rods 16 rotate, since the threaded rods 16 are threaded to the threaded holes at the top of the guide posts 15, the rotation of the threaded rods 16 drives the guide posts 15 to move axially. The movement of the two guide posts 15 drives the same clamping metal block 14 to move. Since the clamping metal block 14 is slidably installed in the guide groove opened on one side of the guide metal block 12, the clamping metal block 14 can only move up and down. The clamping metal block 14 approaches the clamping base 13, thereby clamping the bar 3. The servo motor 9 starts and drives the slider 11 to move, which in turn drives the clamping base 13 and the bar 3 to move, conveying the bar 3 to the designated position for subsequent twist drill production.

[0030] The technological advancements of this invention compared to existing technologies are as follows: it can clamp the bar stock 3 and cooperate with the ball screw 10 to stably and accurately transport the bar stock 3 to the designated position with minimal deviation, greatly improving production accuracy. Furthermore, through the feeding mechanism, the bar stock 3 can be fed autonomously, thereby improving production efficiency.
