Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, and in particular to a drill bit chuck structure. Background Technology

[0002] PCB boards, also known as circuit boards, are used to support, fix, and connect electronic components, and to interconnect electronic components through different forms of circuits. They are widely used in various electrical appliances and automated equipment.

[0003] During the production of PCB boards, many holes need to be drilled to fix various electronic components and for circuit connections. Moreover, the size of the holes will vary depending on the actual needs, and the inner diameter will also vary, ranging from a few millimeters to tens of millimeters. Therefore, when drilling holes in PCB boards using machine tools, it is necessary to change to different sized drill bits.

[0004] Drill bits for machine tools are usually stored in the chuck of the drill bit magazine, also known as the tool magazine chuck. When a drill bit needs to be changed, the corresponding drill bit can be taken out by a robotic arm.

[0005] However, due to the special nature of PCB board processing, static electricity cannot be generated during the process to avoid damaging the circuit board. Therefore, the chuck used to store drill bits is generally made of plastic. After a long period of taking drill bits in and out, wear will occur, making it unusable. At this time, the chuck needs to be replaced.

[0006] However, existing chuck structures are directly fixed in the machine tool's drill bit magazine. When wear occurs, the chuck cannot be replaced quickly, which will affect subsequent PCB board processing. Utility Model Content

[0007] The purpose of this utility model is to solve the technical problem in the prior art that the chuck is directly fixed in the drill bit magazine of the machine tool, and it is impossible to quickly replace the chuck after wear occurs. Therefore, a drill bit chuck structure is proposed.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A drill bit chuck structure includes a base and a placement cylinder, and also includes a chuck strip: the placement cylinder is fixedly connected to the chuck strip; the base is provided with a first chuck groove, and the chuck strip is inserted into the first chuck groove.

[0010] Preferably, the two side walls of the first slot are fixedly connected with protrusions; the two side walls of the card strip are provided with second slots; the protrusions are engaged in the second slots.

[0011] Preferably, both ends of the second slot have a first outward sloping opening.

[0012] Preferably, a baffle is fixedly connected to one end of the first card slot; a first groove is provided at one end of the card strip.

[0013] Preferably, the top inner wall of the placement cylinder has a second outward-curving shape.

[0014] Preferably, the number of the first card slots is 5-10.

[0015] Preferably, the number of placement tubes is 8-20.

[0016] Preferably, the bottom of the placement cylinder is provided with a through hole.

[0017] Preferably, the base is provided with mounting holes.

[0018] Compared with the prior art, the present invention provides a drill bit chuck structure, which has the following beneficial effects:

[0019] 1. With this drill bit chuck structure, when the drill bit wears out due to prolonged use and comes into contact with the placement cylinder, making it unusable, the chuck can be directly pulled out and replaced with a new one, which in turn replaces the placement cylinder without disassembling the base, achieving the purpose of quick replacement and thus avoiding affecting subsequent PCB board processing.

[0020] 2. The drill bit chuck structure features a design where a protruding strip engages with the second slot, serving as a guide during insertion to prevent the chuck from moving upwards. This also prevents the chuck from accidentally wobbling during use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Example:

[0031] Reference Figures 1-6 A drill bit chuck structure includes a base 1 and a placement cylinder 103 for placing drill bits. It also includes a chuck bar 101: the placement cylinder 103 is fixedly connected to the chuck bar 101, and the number of placement cylinders 103 is 8-20. That is, there are 8-20 placement cylinders 103 fixed on the chuck bar 101 for placing drill bits of different models.

[0032] The base 1 is provided with a first card slot 102, and the card strip 101 is inserted into the first card slot 102. After insertion, the side wall of the card strip 101 is tightly attached to the side wall of the first card slot 102.

[0033] The base 1, the card strip 101, and the placement tube 103 are all made of plastic.

[0034] In use, the base 1 is fixed in the drill bit magazine of the machine tool, and then the retaining strip 101 is inserted into the first retaining groove 102. After insertion, since the side wall of the retaining strip 101 is tightly attached to the side wall of the first retaining groove 102, and the plastic material has a certain elasticity, the two will fit tightly together and generate friction to achieve fixation. Then, when in use, the drill bit can be placed directly in the placement cylinder 103.

[0035] When the drill bit wears down and becomes unusable after prolonged use and comes into contact with the placement cylinder 103, simply pull out the retaining strip 101 and replace it with a new one. This also replaces the placement cylinder 103 without disassembling the base 1, achieving a quick replacement and avoiding any impact on subsequent PCB board processing.

[0036] like Figure 2 and Figure 3 The first slot 102 has two protrusions 201 fixedly connected to the two side walls of each side. The number of protrusions 201 on each side is two. The two side walls of the slot 101 are provided with a second slot 2. When the slot 101 is inserted into the first slot 102, the protrusions 201 are engaged in the second slot 2.

[0037] The thickness of the protrusion 201 is the same as the width of the second slot 2, so that the protrusion 201 can be attached to the upper and lower surfaces of the second slot 2.

[0038] The design of the protrusion 201 engaging in the second slot 2 serves as a guide during insertion, preventing the card strip 101 from moving upwards. At the same time, it also prevents the card strip 101 from accidentally shaking during use.

[0039] like Figure 5 Both ends of the second slot 2 have the shape of the first outward-curving opening 3.

[0040] The fact that both ends of the second slot 2 have the first outward-curved opening 3 means that both ends of the inner wall of the second slot 2 are inclined and chamfered to the sides to enlarge the opening. During the insertion process, the protrusion 201 enters the second slot 2 more stably.

[0041] like Figures 3-6 A baffle 4 is fixedly connected to one end of the first card slot 102; a first groove 401 is provided at one end of the card strip 101.

[0042] During insertion, the end with the first groove 401 faces the baffle 4, and then the clip 101 is inserted into the first slot 102. When fully inserted, the first groove 401 is in contact with the baffle 4, which serves as a limit and prevents excessive insertion.

[0043] like Figure 6 The top inner wall of the placement cylinder 103 has a second outwardly inclined opening 301.

[0044] The second outward-curved opening 301 refers to the outward-curving of the inner top wall of the placement cylinder 103, which enlarges the opening and facilitates the placement of the drill bit.

[0045] like Figure 2 and Figure 3 The number of the first card slot 102 is 5-10.

[0046] The base 1 has 5-10 first slots 102, and each first slot 102 is fitted with a clip 101, or the number of clips 101 can be flexibly determined according to the number of drill bits.

[0047] like Figures 4-6 The bottom of the placement cylinder 103 is provided with a through hole 5.

[0048] Through hole 5 is used for venting and plays a role in balancing air pressure.

[0049] When placing the drill bit, the gas at the bottom of the placement cylinder 103 is quickly discharged through the through hole 5, which facilitates the placement of the drill bit; when removing the drill bit, during this process, the gas can quickly enter the placement cylinder 103 through the through hole 5 at the bottom, so that the gas pressure is balanced, which makes it easier to remove the drill bit.

[0050] like Figure 3 and Figure 6 The base 1 is provided with mounting holes 6. The base 1 is fixed in the machine tool drill bit magazine through the mounting holes 6. The mounting holes 6 can be on the two side walls of the base 1 or at the bottom of the first slot 102. Note that when it is located at the bottom of the first slot 102, the bottom of the clip 101 needs to be provided with a second groove 601 to avoid the clip 101 from interfering with the fixing screw.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
