Description
Technical Field
[0001] This utility model belongs to the technical field of drill body processing equipment, and relates to a feeding mechanism for 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 realize drill body transportation and drilling, but there are still shortcomings: for the requirement of radial opening on the outer periphery of the drill body, it is necessary to transport and clamp the upright drill body, and its feeding mechanism is difficult to meet the requirements of stable and efficient feeding. Summary of the Invention
[0005] This utility model addresses the aforementioned problems in existing technologies by providing a feeding mechanism for a drilling equipment. The technical problem this utility model aims to solve is: how to meet the high-efficiency feeding requirements of drilling equipment.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A feeding mechanism for a drilling machine includes a disc-shaped frame and a receiving seat fixed to the frame. The frame is characterized by having a vertically movable clamping seat, an upward-pointing tip, and a feeding seat. The tip is located at the center of the frame. An inner chuck with its lower end directly opposite the tip is connected to the lower side of the clamping seat. The receiving seat has a feeding channel extending from the top to the lower side of the receiving seat, with its lower port vertically downward. A vertically arranged multi-jaw chuck is connected to the upper part of the feeding seat. The feeding seat can move horizontally, with the multi-jaw chuck facing upwards, directly opposite the lower port of the feeding channel and the lower end of the inner chuck.
[0008] The receiving seat can receive drill bodies fed in from the outside. A height-adjustable clamping seat is installed on the frame, with an inner chuck located below the clamping seat. Referring to existing technology, the inner chuck can hold the end of the drill body. A center point with its tip pointing upwards is located at the center of the frame. After holding the upper end of the drill body, the inner chuck can move downwards to position the lower end of the drill body onto the center point, stabilizing the drill body's position and facilitating subsequent drilling around the drill body. During machining, debris can fall from around the center point without affecting the inner chuck, ensuring stable machining and simultaneously receiving the drill body. The base is equipped with a vertically downward-facing feeding channel and a horizontally movable feeding seat. A vertically arranged multi-jaw chuck is connected to the upper part of the feeding seat. The basic structure of the multi-jaw chuck can refer to existing pneumatic chucks, so that when the feeding seat moves horizontally, the multi-jaw chuck can be directly aligned with the lower end of the feeding channel and the lower end of the inner clamp, respectively. In this way, the multi-jaw chuck can form a stable clamp with the end of the drill body falling from the feeding channel, so that it maintains a stable upright state during the process of the receiving seat moving to the bottom of the clamp to facilitate automatic feeding and ensure feeding efficiency.
[0009] In the feeding mechanism of the aforementioned drilling equipment, a vertically mounted lifting cylinder is fixed on the feeding seat, and the multi-jaw chuck is fixed to the output end of the lifting cylinder. Thus, when the feeding seat moves below the unloading channel, the lifting cylinder drives the multi-jaw chuck upwards to the lower end of the unloading channel. Subsequently, the lifting cylinder drives the multi-jaw chuck downwards and horizontally to the inner chuck for clamping, ensuring that the drill body falling from the lower end of the unloading channel can land smoothly and accurately on the multi-jaw chuck for clamping. This results in more precise clamping and facilitates stable and efficient feeding.
[0010] In the feeding mechanism of the aforementioned drilling equipment, the multi-jaw chuck includes several clamping blocks arranged circumferentially at intervals. Each clamping block has a vertically upward-facing, arc-shaped limiting plate, and the limiting plates are arranged in a ring. The multiple clamping blocks close together to clamp the outer periphery of the drill body's end. This allows the limiting plates to limit the protruding shoulder in the middle section of the drill body, preventing the drill body from being misaligned when the multi-jaw chuck begins clamping, thus ensuring smooth and stable clamping and guaranteeing feeding efficiency.
[0011] In the feeding mechanism of the aforementioned drilling equipment, each clamping block has at least two limiting plates. This helps to give the limiting plates better elasticity and avoids damage to the surface of the drill body when they make rigid contact with it.
[0012] In the feeding mechanism of the aforementioned drilling equipment, the upper side of the receiving seat has a strip-shaped accommodating groove, and the unloading channel is arc-shaped and located within the receiving seat. The upper end of the unloading channel is horizontally positioned and connected to the port of the accommodating groove, while the lower end of the unloading channel is vertically downward. This facilitates the horizontal feeding of the drill body, after falling into the accommodating groove, by pushing it horizontally into the unloading channel. The unloading channel guides the change of the drill body's posture, enabling smooth material reception and feeding by the multi-jaw chuck.
[0013] Compared with the prior art, the advantages of this utility model are as follows:
[0014] The feeding mechanism of this drilling equipment enables the multi-jaw chuck to form a stable clamp with the end of the drill body falling from the feeding channel, so that the receiving seat remains in a stable upright state during the process of moving to the bottom of the clamp to facilitate automatic feeding, meet the vertical processing requirements of the drill body and ensure feeding efficiency.

Detailed Implementation
[0022] 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.
[0023] like Figure 1-6 As shown, the drilling equipment includes a disc-shaped frame 1 and a feeding mechanism including a receiving seat 2 fixed on the frame 1. The frame 1 is equipped with a vertically movable clamp 3, a tip 8 with its tip facing upward, and a feeding seat 4. The clamp 3 can be raised and lowered by an existing screw assembly. The tip 8 is located at the center of the frame 1. The lower side of the clamp 3 is connected to an inner chuck 5 with its lower end facing the tip 8. The design of the inner chuck 5 can refer to the existing structure in the background technology center. The receiving seat 2 has a feeding channel 21 that extends from the top to the lower side of the receiving seat 2 and has its lower port facing downward. The feeding seat 4 can be reciprocated by being fixed to the output end of an existing cylinder with its horizontally facing inward. The upper part of the feeding seat 4 is connected to a vertically arranged multi-jaw chuck 6. The basic structure of the multi-jaw chuck 6 can refer to the existing three-jaw chuck. The feeding seat 4 can move horizontally and make the multi-jaw chuck 6 face upward, respectively facing the lower port of the feeding channel 21 and the lower end of the inner chuck 5. A vertically positioned lifting cylinder 7 is fixed to the feeding seat 4, and a multi-jaw chuck 6 is fixed to the output end of the lifting cylinder 7. The multi-jaw chuck 6 includes three circumferentially spaced arc-shaped clamping blocks 61, each clamping block 61 having two vertically upward-facing arc-shaped limiting plates 62, and the six limiting plates 62 are arranged in a ring. The upper side of the receiving seat 2 has a strip-shaped receiving groove 22, and the unloading channel 21 is arc-shaped and located inside the receiving seat 2. The upper end of the unloading channel 21 is horizontally positioned and connected to the port of the receiving groove 22, and the lower end of the unloading channel 21 is vertically downward.
[0024] During feeding, the external drill body 9 can first be fed into the receiving slot 22 of the receiving seat 2. Then, through the existing pushing structure, the drill body 9 can be pushed into the unloading channel 21, causing it to slide downwards and be adjusted to an upright state. At this time, the feeding seat 4 has driven the multi-jaw chuck 6 to move below the lower port of the unloading channel 21, and under the action of the lifting cylinder 7, it approaches the lower port of the unloading channel 21, so that the drill body 9 can fall stably onto the multi-jaw chuck 6 and be clamped by it. After that, the lifting cylinder 7 resets downwards, and the feeding seat 4 can move horizontally to the lower part of the clamping seat 3. The lifting cylinder 7 drives the multi-jaw chuck 6 to move upwards again, so that the inner chuck 5 can clamp the drill body 9. Then, the lifting cylinder 7 resets downwards, the feeding seat 4 moves horizontally outwards, and finally the clamping seat 3 moves downwards and cooperates with the lower tip 8 to form a stable clamping of the drill body 9 for subsequent processing.
[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
