Description

Technical Field

[0001] This utility model belongs to the technical field of drill body processing equipment, and relates to a drill body drilling equipment. Background Technology

[0002] Drill chucks are a key accessory in the power tool and machine tool industries, widely used in electric drills and drilling machines. Existing drill chucks generally consist of a drill body with a connecting hole at the rear end for mates with the motor shaft. At the front end of the drill body, three jaw holes are evenly arranged circumferentially, inclined towards the centerline of the drill body. These jaw holes have the same inclination angle and contain jaws that can slide back and forth within them. The rear end of each jaw is threaded. The drill chuck includes a nut that surrounds the drill body and is axially constrained, with the nut threadedly connected to the jaws. Currently, the drill chuck needs to be engaged with a robot arm via a quick-release mechanism. Therefore, multiple circular holes need to be drilled on the outer circumference of the rear end of the drill body to ensure stable engagement with the drill body when the steel balls in the quick-release mechanism move radially inward. This requires drilling equipment to machine these circular holes.

[0003] The applicant previously developed a jaw hole processing device for a drill chuck with application number CN202311867754.2, which includes a frame, a positioning mechanism, a drilling mechanism, a material handling mechanism, and a loading mechanism and a unloading mechanism arranged side by side. A turntable is rotatably connected to the middle of the frame. There are several positioning mechanisms that are evenly distributed around the turntable. The number of drilling mechanisms is one less than that of the positioning mechanisms and they are evenly distributed around the turntable along with the material handling mechanism. The positioning mechanism includes a positioning screw and a driving component one that drives the positioning screw to rotate. The material handling mechanism includes two clamps arranged side by side, a driving component two that drives the two clamps to rotate, a driving component three that drives the two clamps to move back and forth between the loading / unloading mechanism and the positioning mechanism, and a driving component four that drives the two clamps to move along the distribution direction.

[0004] The above-mentioned equipment can drill holes in the drill body, but it still has shortcomings: for the radial opening requirements of the drill body, in order to ensure the clamping strength, the number of openings must be much more than three. For this reason, multiple drilling machines need to be set up to carry out drilling processing. Therefore, the circumferential space in the processing position is very limited. The loading and unloading mechanism of the above-mentioned equipment will cause spatial interference with the drilling machine. At the same time, it cannot meet the needs of conveying and processing the vertical drill body, making it difficult to guarantee processing efficiency. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a drilling device. The technical problem this utility model aims to solve is: how to ensure processing efficiency while maintaining a compact structure.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A drilling device includes a disc-shaped frame with several drilling machines arranged at intervals around the center of the frame and with their output ends facing inward. The frame is characterized by further having an upward-pointing center, a vertically movable clamping seat, and a conveyor belt arranged horizontally along the radial direction of the frame. The center is located at the center of the frame, and an inner chuck is located on the lower side of the clamping seat, directly opposite the center. The conveyor belt is located between two adjacent drilling machines and below their output ends. One end of the conveyor belt is positioned close to the center, and the other end extends out of the frame. The frame also has a clamp located directly above the conveyor belt and movable along its length to below the inner chuck, with the clamp positioned above the output end of the drilling machine.

[0008] The output end of the drilling machine is used to drill holes by interacting with the outer periphery of the drill body. An upward-facing center is positioned at the center of the frame, along with a vertically adjustable clamping seat. An inner chuck is located below the clamping seat, directly opposite the center. This allows the inner chuck to grip the upright drill body and then move downwards to engage with the center, positioning the drill body. This facilitates simultaneous processing by multiple drilling machines. A conveyor belt is installed radially along the frame between two drilling machines, positioned below the output end of each machine. A clamping jaw, positioned above the conveyor belt and above the output end, holds the drill body and extends along the length of the conveyor belt. The machine moves back and forth, so that after the drill body is drilled, the clamping seat rises and lifts, and then the jaws can move horizontally to the bottom of the inner chuck to clamp the finished drill body. Then the jaws retract to the top of the conveyor belt and release the drill body, which can fall downward onto the conveyor belt and be automatically transported to the outside of the frame. This realizes the processing of the radial hole of the drill body and automatic unloading, ensuring processing efficiency. At the same time, the jaws and the conveyor belt are respectively set on the upper and lower sides of the output end of the drilling machine, which is conducive to making full use of the space above and below the output end of the drilling machine when a sufficient number of drilling machines are arranged in the circumferential direction. This ensures processing efficiency while making the overall structure more compact.

[0009] In the aforementioned drilling equipment, limiting vertical plates are provided on both sides of the conveyor belt in the width direction, fixed to the frame and arranged along the length direction of the conveyor belt. This ensures that even if the drill body falling onto the conveyor belt bounces, it will be restrained by the limiting vertical plates, preventing it from slipping off the conveyor belt and making the output of the drill body more stable.

[0010] In the aforementioned drilling equipment, the frame has a downward-facing through hole at its center, and a crossbeam is fixed to the frame above the through hole. The tip is fixed to the crossbeam. This allows debris generated during drilling to fall downwards into the through hole below the crossbeam for easy collection and processing.

[0011] In the aforementioned drilling equipment, the frame is funnel-shaped with the larger end facing upwards. The upper side of the frame has several support platforms arranged at intervals around the through hole. The drilling rig is slidably connected to each support platform and can reciprocate radially along the frame. This facilitates the guide of debris that does not directly fall into the through hole, allowing for centralized collection and processing.

[0012] In the aforementioned drilling equipment, a cylindrical support sleeve is fixed to the upper side of the crossbeam. The upper end of the support sleeve is a truncated cone shape with the smaller end facing upwards. The support sleeve is fitted around the outer periphery of the tip, with the upper end of the tip extending beyond the upper end of the support sleeve. In this way, the support sleeve can guide the debris scattered from the drill body on the tip to slide down to the surrounding area, thereby preventing it from accumulating on the crossbeam.

[0013] In the aforementioned drilling equipment, the frame is further equipped with a feeding seat that can move radially towards the frame to below the inner chuck. This feeding seat has an upward-facing multi-jaw chuck. The feeding seat is located between two adjacent drilling machines and is circumferentially spaced from the conveyor belt. The feeding seat is positioned higher than the output end of the drilling machine. This allows the multi-jaw chuck to grip the drill body in an upright position, and then the feeding seat can move the drill body to the center of the frame for gripping by the inner chuck for processing, ensuring processing efficiency. Simultaneously, the feeding seat and conveyor belt are arranged between different drilling machines and avoid the output end of the drilling machines, effectively utilizing limited space and ensuring a compact structure.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] After the drilling of the drill body is completed, the chuck can move horizontally to the bottom of the inner chuck to pick up the finished drill body and retract it to the top of the conveyor belt to release the drill body, realizing automatic unloading of the drill body and ensuring processing efficiency. At the same time, the chuck and the conveyor belt are respectively set on the upper and lower sides of the output end of the drilling machine, which is conducive to making full use of the space above and below the output end of the drilling machine under the condition of circumferentially arranging a sufficient number of drilling machines, meeting the needs of multi-hole processing of the drill body, and making reasonable use of space to ensure processing efficiency.

Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1-2 As shown, this drilling equipment includes a disc-shaped frame 1. Multiple drilling machines 2 are arranged horizontally around the center of the frame 1 with their output ends facing inwards. The drilling machines 2 are existing components. The frame 1 also has a vertically adjustable clamping seat 3 and a conveyor belt 4 arranged horizontally along the radial direction of the frame 1. The conveyor belt 4 is an existing component. The clamping seat 3 can be raised and lowered using an existing screw assembly. The frame 1 also has a gripper 6 located directly above the conveyor belt 4 and movable along the length of the conveyor belt 4 to below the inner chuck 5. The structure of the gripper 6 can refer to existing horizontally opening and closing clamping assemblies. The frame also has a feeding track 104 and a receiving seat 105 to feed external drill bodies 103 into the frame 1. The basic structure of the feeding track 104 and the receiving seat 105 can refer to the corresponding existing structures in the background art.

[0025] like Figure 3-6As shown, the frame 1 is also equipped with a tip 102 pointing upwards, located at the center of the frame 1. An inner chuck 5, directly opposite the tip 102, is located on the lower side of the clamp 3. A conveyor belt 4 is positioned between two adjacent drilling machines 2 and is below the output end of the drilling machine 2. One end of the conveyor belt 4 is close to the tip 102, and the other end extends out of the frame 1. The clamp 6 is positioned above the output end of the drilling machine 2. Limiting vertical plates 7, fixed to the frame 1 and arranged along the length of the conveyor belt 4, are provided on both sides of the conveyor belt 4 in the width direction. The frame 1 has a through hole 11 pointing downwards at its center. A crossbeam 8 is fixed above the through hole 11 on the frame 1, and the tip 102 is fixed to the crossbeam 8. The frame 1 is funnel-shaped with the larger end pointing upwards. Several support platforms 12 are spaced around the through hole 11 on the upper side of the frame 1. The drilling machines 2 are slidably connected to the support platforms 12 and can reciprocate radially along the frame 1. A cylindrical support sleeve 9 is fixed to the upper side of the crossbeam 8. The upper end of the support sleeve 9 is a truncated cone with the small end facing upward. The support sleeve 9 is fitted around the outer periphery of the tip 102, and the upper end of the tip 102 extends out of the support sleeve 9. The frame 1 is also provided with a feeding seat 10 that can move radially along the frame 1 to below the inner chuck 5. The feeding seat 10 achieves horizontal reciprocating movement by being fixed to the output end of an existing horizontally arranged cylinder. The feeding seat 10 has an upwardly arranged multi-jaw chuck 101. The structure of the multi-jaw chuck 101 can refer to the existing three-jaw chuck. The feeding seat 10 is located between two adjacent drilling machines 2 and is circumferentially spaced from the conveyor belt 4. The position of the feeding seat 10 is higher than the output end of the drilling machine 2. The receiving seat 105 is provided with a downwardly connected unloading channel (not shown) for the vertical sliding of the drill body, which facilitates the multi-jaw chuck 101 to receive materials from the lower port of the unloading channel and feed them one by one to the clamp 3.

[0026] During processing, the upright drill body 103 is held by the multi-jaw chuck 101 on the feed seat 10. The feed seat 10 moves down to below the clamping seat 3. After the inner chuck 5 clamps the drill body 103, the feed seat 10 moves outward and the clamping seat 3 moves down to cooperate with the lower tip 102 to form a stable clamping of the drill body 103. Then, multiple drilling machines 2 drill holes on the outer periphery of the drill body 103. After processing, the clamping seat 3 drives the drill body 103 to move upward. Then, the jaws 6 move towards the drill body 103 and clamp the drill body 103. The inner chuck 5 releases the drill body 103 and continues to move upward. Then, the jaws 6 retract and release the drill body 103, which falls onto the conveyor belt 4 and is finally sent to the outside of the frame 1 for unloading.
