Description

Technical Field

[0001] This utility model relates to the field of drill bit holders, and more particularly to a drill bit holder for a drilling machine. Background Technology

[0002] In fields such as machining, drilling machines are widely used as core processing equipment. Drill bits, as key consumables for drilling machines, come in various specifications. Due to their sharp tips and high surface precision requirements, they need to be stored and protected in an orderly manner using a special rack to ensure the accuracy of subsequent drilling operations.

[0003] Currently, traditional drill bit racks are mainly divided into two categories: open-air placement structures and enclosed box-type placement structures. However, both types of racks still have shortcomings in actual use.

[0004] While open-air racks allow for quick access to drill bits, the lack of effective protective structures means that drill bits exposed to the air for extended periods are prone to accumulating dust, oil, and other impurities. These impurities can affect the fit between the drill bit and the workpiece, leading to decreased drilling accuracy. Furthermore, workers are at risk of being scratched by sharp points during handling or tidying, posing a safety hazard. While enclosed box racks can isolate external impurities and protect the drill bit surface to some extent, the depth of the rack's slots is often greater than the length of the drill bit. Once placed in the rack, the top of the drill bit can easily sink into the slot, requiring fingers to be inserted to retrieve it, which is inconvenient and also carries the risk of being scratched by sharp points.

[0005] To address this problem, a drill bit holder for a drilling machine is proposed. Summary of the Invention

[0006] To overcome the above shortcomings, this utility model provides a drill bit placement rack for a drilling machine, which aims to improve the problems of poor protection of open-air placement racks, easy contamination of drill bits and safety hazards when picking them up and putting them down, and inconvenience of picking up materials with box-type placement racks.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a drill bit placement rack for a drilling machine, including a support frame, an insertion hole through the inner surface of the support frame, a protective cover threaded to the top of the outer wall of the support frame, a rotating ring rotatably connected to the bottom of the outer wall of the support frame, a base slidably connected to the outer wall of the rotating ring, and a material picking mechanism provided inside the base. The material handling mechanism includes an ejection assembly, which includes a connecting plate. The connecting plate is slidably connected to the left surface of the base. A top block is fixedly connected to the right end of the connecting plate. A locking block is elastically connected to the inner wall of the bottom of the base via a connecting spring. A locking groove is formed through the inner surface of the connecting plate. A placement cylinder is slidably connected through the lower surface of the insertion hole. A positioning block is fixedly connected to the lower surface of the placement cylinder.

[0008] As a further description of the above technical solution: The material handling mechanism further includes a positioning component, which includes a pull ring. A slide rod is fixedly connected to the right surface of the pull ring. A connecting rod is fixedly connected through the middle section of the inner surface of the slide rod. A push block is elastically connected to the right end of the outer wall of the slide rod via a torsion spring. A slot is provided on the inner surface of the base. A limit groove is provided on the inner surface of the base. The push block is slidably connected to the inner wall of the limit groove. A limit block is elastically connected to the inner wall of the rotating ring via a compression spring.

[0009] As a further description of the above technical solution: The support frame is stepped, and the upper half of the top block is a cone with the tip pointing upwards.

[0010] As a further description of the above technical solution: The card block is slidably connected to the inner wall of the base, and the upper half of the card block is set as a "hemispherical" and the card block is inserted into the inner wall of the card slot.

[0011] As a further description of the above technical solution: One side of the outer surface of the positioning block is set as an inclined surface. Multiple sets of the insertion hole, placement cylinder and positioning block are provided. The multiple sets of insertion hole, placement cylinder and positioning block are distributed in inner and outer rings on the support frame.

[0012] As a further description of the above technical solution: The diameter of the insertion holes and placement cylinders located near the inner ring of the support frame is larger than that of the insertion holes and placement cylinders located away from the inner ring of the support frame. Multiple sets of insertion holes, placement cylinders, and positioning blocks located in the same ring are arranged in a circular array with the center of the support frame as the origin.

[0013] As a further description of the above technical solution: The slide bar passes through and is rotatably connected to the left surface of the push block, and the connecting rod is inserted into the inner wall of the slot.

[0014] As a further description of the above technical solution: The limiting block is slidably connected to the left surface of the rotating ring, the limiting block is inserted into the inner wall of the limiting groove, and the upper half of the left surface of the limiting block is set as an inclined surface that gradually slopes upward from left to right.

[0015] This utility model has the following beneficial effects: 1. In this utility model, the problem of poor protection of open-air placement racks is solved by the cooperation of protective cover and placement cylinder.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a drill bit placement rack for a drilling machine, including a support frame 1 for supporting the drill bit. The inner surface of the support frame 1 has a through hole 5 through which the drill bit is inserted. The top of the outer wall of the support frame 1 is threaded with a protective cover 2, which can protect the drill bit and ensure the stability of the drill bit placement state. The bottom of the outer wall of the support frame 1 is rotatably connected with a rotating ring 3. The rotating ring 3 and the support frame 1 are in a "transition fit" and will not rotate under the influence of no external force. The outer wall of the rotating ring 3 is slidably connected with a base 4, which moves longitudinally. The base 4 is provided with a material picking mechanism inside.

[0021] Reference Figure 2 - Figure 4 The material handling mechanism includes an ejection assembly 7 for ejecting the required drill bit. The ejection assembly 7 includes a connecting plate 71, which is slidably connected to the left surface of the base 4. A top block 72 is fixedly connected to the right end of the connecting plate 71. When the top block 72 moves to the rightmost end, its center is on the same axis as the center of the innermost insertion hole 5. A locking block 74 is elastically connected to the inner wall of the bottom end of the base 4 through a connecting spring 73. A slot 75 is opened through the inner surface of the connecting plate 71. The locking block 74 and the slot 75 fit together. There are three sets of slots 75, which are distributed horizontally at equal intervals. A placement cylinder 76 for accommodating the drill bit is slidably connected through the lower surface of the insertion hole 5. The inner surface of the placement cylinder 76 is made of rubber. When the drill bit is inserted, the sharp end can face down to ensure that it will not scratch the hands of personnel when it is picked up later. The rubber material can prevent damage to the sharp end of the drill bit. A positioning block 77 is fixedly connected to the lower surface of the placement cylinder 76.

[0022] Reference Figure 2 - Figure 4The support frame 1 is stepped, and the upper half of the top block 72 is a cone with its tip pointing upwards. The top block 72 facilitates the subsequent pressing of the positioning block 77 to push out the drill bit, making it easy to pick up. The locking block 74 is slidably connected to the inner wall of the base 4. The locking block 74 moves longitudinally. When the locking block 74 moves downwards, it will press the connecting spring 73 to generate a reaction force. The upper half of the locking block 74 is a hemisphere. When the upper half of the locking block 74 is pressed from the side, it will move downwards. The locking block 74 is inserted into the inner wall of the slot 75. When the locking block 74 moves downwards, it will disengage from the slot 75 and release the limit. One side of the outer surface of the positioning block 77 is set as a slope, which corresponds to the top block 72. The insertion hole 5 Multiple sets of insertion holes 5, insertion cylinders 76, and positioning blocks 77 are provided on the support frame 1. The insertion holes 5 and insertion cylinders 76 located near the inner circle of the support frame 1 have larger diameters than those located away from the inner circle. A drill bit of a matching size is placed inside the insertion cylinder 76. The multiple sets of insertion holes 5, insertion cylinders 76, and positioning blocks 77 located in the same circle are arranged in a circumferential array with the center of the support frame 1 as the origin. By changing the position of the top block 72 from the center of the support frame 1, the size of the drill bit being lifted can be changed. By rotating the support frame 1, the model of the drill bit being lifted can be changed.

[0023] Reference Figure 2 , Figure 4 , Figure 5 The material handling mechanism also includes a positioning component 6, which includes a pull ring 61 for easy pulling. A slide rod 62 is fixedly connected to the right surface of the pull ring 61. The slide rod 62 passes through the left surface of the base 4. A connecting rod 63 for positioning the slide rod 62 passes through and is fixedly connected to the middle section of the inner surface of the slide rod 62. A push block 65 is elastically connected to the right end of the outer wall of the slide rod 62 through a torsion spring 64. When the slide rod 62 rotates, it will compress the torsion spring 64 to generate a reaction force. A slot 66 is opened on the inner surface of the base 4. A limit groove 67 is opened on the inner surface of the base 4. Two sets of limit grooves 67 are opened and are distributed longitudinally at equal intervals. The push block 65 is slidably connected to the inner wall of the limit groove 67. A limit block 68 is elastically connected to the inner wall of the rotating ring 3 through a compression spring 69.

[0024] Reference Figure 2 , Figure 4 , Figure 5The sliding rod 62 passes through and is rotatably connected to the left surface of the push block 65. The connecting rod 63 is inserted into the inner wall of the slot 66. The connecting rod 63 can only be aligned with the slot 66 after rotating 90 degrees. The limiting block 68 passes through and is slidably connected to the left surface of the rotating ring 3. The limiting block 68 is inserted into the inner wall of the limiting groove 67, which can limit the height of the support frame 1. The upper half of the left surface of the limiting block 68 is set as an inclined surface that gradually slopes upward from left to right. When the inclined surface is squeezed, the limiting block 68 will move to the right to release the obstruction. When the limiting block 68 moves upward, the inclined surface will be squeezed by the base 4. Therefore, the limiting block 68 can only achieve the function of unidirectional limiting.

[0025] Working principle: When the device is idle, the rotating ring 3 remains stationary due to the "transition fit" when there is no external force, which prevents the support frame 1 from rotating at will. The protective cover 2 seals the top of the support frame 1, which can isolate external dust and moisture and provide protection for the drill bit.

[0026] When placing drill bits, drill bits of different specifications are inserted into the corresponding placement cylinders 76 through the insertion holes 5 on the support frame 1. When the drill bits need to be removed, the position of the support frame 1 needs to be adjusted downwards first. During adjustment, rotating the pull ring 61 drives the slide rod 62 and the connecting rod 63 to rotate synchronously, and the slide rod 62 will compress the torsion spring 64 to generate a reaction force. When the connecting rod 63 and the slot 66 are aligned, the pull ring 61 is moved to the right, which drives the connecting rod 63, the slide rod 62 and the push block 65 to move to the right, pushing out the limiting block 68 that is stuck in the limiting groove 67 to release the limit. When the limiting block 68 moves, it will compress the compression spring 69 to generate a reaction force. After the limit is released, the support frame 1 is moved downwards. When the limiting block 68 is aligned with the lower limiting groove 67, it will be inserted under the force of the compression spring 69 to limit the support frame 1.

[0027] Then, adjust the position of the top block 72 according to the required drill bit size. During adjustment, simply move the connecting plate 71 horizontally. In this process, the connecting plate 71 will press the arc surface of the locking block 74 to move it down to release the limit and press the connecting spring 73 to generate a reaction force. When it moves to the appropriate position, the connecting spring 73 will push the locking block 74 out and insert it into the slot 75 at that position for positioning. Then rotate the support frame 1. When rotating, the top block 72 will press the inclined surface of the positioning block 77 at different positions and drive the placement cylinder 76 connected to it and the corresponding drill bit to move upward and protrude from the support frame 1 for easy removal. After removal, push the connecting plate 71 to the rightmost point, pull the pull ring 61 to the left, and then move the support frame 1 upward to reset the device. When the pull ring 61 moves to the left end, the torsion spring 64 will drive the pull ring 61 to rotate in the opposite direction to the initial position. When the support frame 1 moves upward, the inclined surface of the limiting block 68 will be pressed and cannot form a limit.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
