Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and in particular to a drilling device for processing umbrella ribs. Background Technology

[0002] Umbrellas are an essential tool for people to protect themselves from rain on rainy days. The umbrella ribs, which support the umbrella frame, are generally made of materials such as iron, steel, and aluminum alloy. During the manufacturing process, holes need to be drilled in the umbrella ribs before subsequent installation.

[0003] For example, Chinese utility model patent application number CN202322388168.1 discloses a device for drilling holes in umbrella ribs during umbrella processing, relating to the field of umbrella processing. It includes a frame, a first cylinder fixedly mounted on the frame, a clamping plate fixedly mounted at the end of the first cylinder, a feeding assembly installed inside the frame, a hollow rotating cylinder movably mounted inside the frame with its lower end above a waste material chute, a feeding tray fixedly mounted at the upper end of the hollow rotating cylinder with umbrella rib slots on the tray, a driven gear fixedly mounted on the hollow rotating cylinder, a servo motor fixedly mounted inside the frame on one side of the driven gear, a drive gear fixedly mounted at the output end of the servo motor, and a drilling mechanism located above the feeding tray inside the frame. After the umbrella ribs move below the drilling mechanism, the first cylinder can be activated, causing the clamping plate to press the umbrella ribs together. After the umbrella ribs are pressed together, a second cylinder and a drill can be activated, causing the drill bit on the drill to move downwards, thereby automatically drilling holes in the umbrella ribs and improving drilling efficiency.

[0004] Although the aforementioned punching device can punch holes in the umbrella ribs, it cannot accurately position the ribs after they are placed in the rib groove. Furthermore, the feeding tray cannot fix the ribs during rotation, which makes the ribs prone to displacement. This results in deviations in the hole positions after punching, rendering the ribs unusable. Utility Model Content

[0005] This utility model discloses a drilling device for processing umbrella ribs, which solves the problems that the umbrella ribs cannot be accurately positioned after being placed in the rib groove, and the feeding tray cannot fix the umbrella ribs during rotation, resulting in displacement of the umbrella ribs and deviation of the hole position after drilling.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A drilling device for processing umbrella ribs includes a worktable, a ring on top of the worktable, a set of rib grooves on the top of the ring, and a groove at the center of the ring that communicates with the rib grooves; a cylinder inside the ring, with a first semicircular plate and a second semicircular plate forming a ring, each corresponding to a groove; two electric telescopic rods inside the cylinder, used to drive the first and second semicircular plates to rise and fall respectively; a fixed frame on the worktable, with a first automatic telescopic rod located above the ring on the fixed frame, a first motor at the telescopic end of the first automatic telescopic rod, and a drill bit mounted on the shaft of the first motor; and a second motor on the worktable for driving the ring to rotate.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] After placing the umbrella ribs in the rib slots, ensure one end of each rib is in contact with the outer wall of the cylinder and positioned below the first semicircular plate. Then, activate the electric telescopic rod controlling the first semicircular plate to move it downwards, pressing down on and securing the ribs. Next, activate the second motor to drive the ring to rotate, causing the electric telescopic rod to move the first semicircular plate upwards. Place the other rib into the second rib slot, ensuring one end is in contact with the outer wall of the cylinder. Move the first semicircular plate downwards again to secure the rib. Repeat this process, placing the ribs to be drilled into a set of rib slots, and then using the first and second semicircular plates to press and secure them. The cylinder provides precise positioning for the ribs. Finally, the telescopic end of the first automatic telescopic rod drives the first motor downwards. Once the first motor starts, the drill... As the head moves and the drill bit moves downward with motor number one, it can drill holes in the umbrella ribs located in the rib slots. During the drilling process, the ribs will not shift. Subsequently, through the rotation of the ring, the drill bit can sequentially drill holes in the ribs fixed by the first and second semicircular plates. The arrangement of the first and second semicircular plates allows for easy removal of the drilled rib when drilling begins, as the rib fixed by the second semicircular plate is moved upward. This improves drilling efficiency. This invention effectively and precisely positions and fixes the umbrella ribs, preventing displacement during movement or drilling, and ensuring that the holes are in the designated positions after drilling.

[0015] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a drilling device for processing umbrella ribs, including a workbench 1, a ring 2 above the workbench 1, a set of umbrella rib grooves 21 on the top of the ring 2, and a groove 22 connected to the set of umbrella rib grooves 21 at the center of the ring 2; a cylinder 3 is provided inside the ring 2, and a first semicircular plate 31 and a second semicircular plate 32 forming a ring are provided on the cylinder 3, the first semicircular plate 31 and the second semicircular plate 32 are respectively corresponding to the groove 22, and two electric telescopic rods 33 are provided inside the cylinder 3, which are used to drive the first semicircular plate 31 and the second semicircular plate 32 to rise and fall respectively; a fixing frame 4 is fixed on the workbench 1, and a first automatic telescopic rod 5 located above the ring 2 is provided on the fixing frame 4, and a first motor 51 is provided at the telescopic end of the first automatic telescopic rod 5, and a drill bit 52 is installed on the shaft of the first motor 51; a second motor 6 is provided on the workbench 1 to drive the ring 2 to rotate.

[0017] like Figure 1As shown, the telescopic end of the first automatic telescopic rod 5 is fixed with a lifting plate 53, the main body of the first motor 51 is fixed on the lifting plate 53, the fixed end of the first automatic telescopic rod 5 is fixed with a slider 54, the top of the fixing frame 4 has a straight opening, and the slider 54 is slidably connected in the opening; the top of the fixing frame 4 is provided with a lead screw 41 that is threadedly connected to the slider 54, the fixing frame 4 is fixed with a third motor 42 for driving the lead screw 41, and the top of the fixing frame 4 is fixed with a fixing plate 43 that is rotatably connected to the end of the lead screw 41 away from the third motor 42. After starting the No. 1 automatic telescopic rod 5, the telescopic end of the No. 1 automatic telescopic rod 5 can drive the No. 1 motor 51 to move up or down through the lifting plate 53, so that the drill bit 52 can move down to drill holes in the umbrella rib. The No. 3 motor 42 is a servo motor. The rotating shaft of the No. 3 motor 42 is fixed to the end of the lead screw 41. After starting the No. 3 motor 42 to rotate the lead screw 41, the slider 54 can move left or right, so that the No. 1 automatic telescopic rod 5 drives the No. 1 motor 51 to move and change the position of the drill bit 52 so that the drill bit 52 can correspond to the part of the umbrella rib that needs to be drilled.

[0018] like Figure 1 As shown, a vertical cylinder 7, which passes through the top of the workbench 1 and is rotatably connected to the workbench 1, is fixed to the bottom of the ring 2. A transmission belt 8 is provided above the workbench 1. A second motor 6 is connected to the vertical cylinder 7 via the transmission belt 8. A support rod 24, which is slidably connected to the top of the workbench 1, is fixed to the bottom of the ring 2. A storage battery 23 is fixed on the ring 2. Pulleys adapted to the transmission belt 8 are fixed to the shaft of the second motor 6 and the vertical cylinder 7, respectively. After the second motor 6 is started, the vertical cylinder 7 can be driven to rotate via the transmission belt 8, so as to make the ring 2 rotate. A ring-shaped groove is opened on the top of the workbench 1. The bottom of the support rod 24 is slidably connected in the groove to increase the stability of the ring 2. The storage battery 23 can supply power to the electric telescopic rod 33.

[0019] like Figure 1 , Figure 3 and Figure 4As shown, a fixed beam 71 is fixed inside the vertical cylinder 7. A second automatic telescopic rod 72 is fixed to the top of the fixed beam 71. A T-shaped connecting rod 73 is fixed to the telescopic end of the second automatic telescopic rod 72. The two opposite ends of the connecting rod 73 are fixed to the inner wall of the cylinder 3, and the outer wall of the cylinder 3 is in contact with the inner wall of the ring 2. A folded tube 74 is fixed to the bottom end of the connecting rod 73, which is fixed to the top of the fixed beam 71 and covers the second automatic telescopic rod 72. The groove 22 is arranged in a ring shape, and the bottom of the groove 22 is flush with the bottom of the umbrella rib groove 21. When waste accumulates in the umbrella rib groove 21 or the groove 22 and needs to be cleaned, the second automatic telescopic rod 72 can be activated to drive the connecting rod 73 to move the cylinder 3 upward, so that the bottom of the cylinder 3 moves above the top of the ring 2, so that the workers can clean the waste in the umbrella rib groove 21 or the groove 22 toward the axis of the ring 2, so that the waste falls downward through the inner side of the ring 2 into the vertical cylinder 7, and then is discharged through the bottom of the vertical cylinder 7 for waste collection. The folding tube 74 can prevent the second automatic telescopic rod 72 from contacting the waste, thus protecting the second automatic telescopic rod 72, and the battery 23 can supply power to the second automatic telescopic rod 72.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the telescopic ends of the electric telescopic rods 33 are fixed with fixing rods 34. The ends of the two fixing rods 34 located outside the cylinder 3 are respectively fixed to the first semicircular plate 31 and the second semicircular plate 32. After the two electric telescopic rods 33 are started, the telescopic ends of the two electric telescopic rods 33 drive the first semicircular plate 31 and the second semicircular plate 32 to move upward or downward through the fixing rods 34.

[0021] like Figure 2 and Figure 3 As shown, the top of the ring 2 is inlaid with two automatic telescopic rods 9 arranged left and right. The telescopic ends of the three automatic telescopic rods 9 are fixed with arc-shaped strips 91. When the part of the umbrella rib that needs to be drilled is blocked by the first semicircular plate 31 or the second semicircular plate 32, the two electric telescopic rods 33 can be activated to drive the first semicircular plate 31 and the second semicircular plate 32 downwards, so that the bottom of the first semicircular plate 31 and the second semicircular plate 32 contacts the bottom of the groove 22. Then, after the worker places the umbrella rib into the rib groove 21, one end of the umbrella rib contacts the outer wall of the first semicircular plate 31 or the second semicircular plate 32, thus positioning the umbrella rib. Then, the two automatic telescopic rods 9 are activated again, and the telescopic ends of the three automatic telescopic rods 9 drive the arc-shaped strips 91 downwards, so that the bottom of the arc-shaped strips 91 contacts the top of the ring 2, thus pressing down the umbrella rib located in the rib groove 21 and fixing the umbrella rib. Figure 2As shown, a set of umbrella rib grooves 21 is divided into two parts. Two arc-shaped strips 91 fix a portion of the umbrella rib groove 21. The arc-shaped strip 91 on the left can press down the umbrella rib that contacts the first semicircular plate 31, while the arc-shaped strip 91 on the right can press down the umbrella rib that contacts the second semicircular plate 32. Figure 1 (as shown in the diagram), and then the drill bit 52 can be used to drill holes in the parts of the umbrella rib that need to be drilled; the battery 23 can supply power to the No. 3 automatic telescopic pole 9.

[0022] In use, several umbrella ribs to be drilled are placed in a set of rib grooves 21, with one end of each rib in contact with the outer wall of the cylinder 3 to position them. Some ribs are located below the first semicircular plate 31, and others below the second semicircular plate 32. The two electric telescopic rods 33 are then activated to move the first and second semicircular plates 31 and 32 downwards, pressing the ribs down and fixing them in place. Then, the second motor 6 is activated to drive the ring 2 to rotate, positioning one rib directly below the drill bit 52. The first automatic telescopic rod 5 and the first motor 51 are then activated to move the drill bit 52 downwards and drill the ribs. Once all the ribs below the first semicircular plate 31 have been drilled, drilling begins on the ribs below the second semicircular plate 32. The operator can then move the first semicircular plate 31 upwards to remove the drilled ribs and replace them with the ones to be drilled.
