Description

Technical Field

[0001] This utility model relates to the field of drill bit chuck technology, and in particular to a magnetic chuck device for quick drill bit replacement. Background Technology

[0002] In the process of circuit board production, it is necessary to drill holes in the circuit board to facilitate the installation of electronic components. Since the drill bit used for drilling circuit boards is small, the drill bit often breaks during the drilling process, so the drill bit needs to be replaced frequently. In the existing technology, drill bit chucks for drilling circuit boards typically use threaded locking to lock the drill bit. Threaded locking has problems such as low drill bit replacement efficiency, the need to manually rotate the locking mechanism, cumbersome operation, and long time consumption. In addition, long-term twisting of the threaded locking structure can easily cause the thread to strip, affecting the drill bit locking. Therefore, a magnetic chuck device for quick drill bit replacement is designed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a magnetic chuck device for quick drill bit replacement.

[0004] The technical problem to be solved by this utility model is to provide a magnetic chuck device for quick drill bit replacement, which solves the problem that the drill bit chuck for circuit board drilling usually uses a threaded locking method to lock the drill bit, which has the problems of low drill bit replacement efficiency, easy thread stripping, and affecting the locking effect of the drill bit.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic chuck device for quick drill bit replacement, comprising a chuck body, a drill bit mounting groove, a through groove, a connecting component, and clamping blocks. The drill bit mounting groove is provided in the center of the left end of the chuck body. Through grooves are provided in the four directions of the drill bit mounting groove: up, down, inside, and outside. Multiple clamping blocks are connected to the right end of the drill bit mounting groove through the connecting component. The connecting assembly includes a fixed plate fixed inside the right end of the drill bit mounting slot. Guide rods are fixedly provided on the four sides of the fixed plate in the inner, outer, upper, and lower directions. A through hole is provided through the right end of the clamping block, and the guide rods pass through the through hole. A sleeve spring is fixedly provided between the clamping block and the fixed plate. A magnetic locking assembly is installed on the right side of the outer surface of the chuck body to drive the clamping block to move towards the drill bit mounting slot and clamp the drill bit installed in the drill bit mounting slot.

[0006] Preferably, the clamping block matches the through slot, and the clamping block can move along the through slot towards the side closer to the drill bit mounting slot and away from the drill bit mounting slot.

[0007] Preferably, the clamping block is trapezoidal in shape with a thickness that gradually decreases at the right end, and when the sleeve spring is in its natural extended state, the right end of the clamping block is completely inside the through groove, while the left end of the clamping block extends out of the through groove.

[0008] Preferably, the fixing plate is made of magnetic material.

[0009] Preferably, the magnetic locking assembly includes a fixing ring, a through rod, an electromagnetic ring, and a locking ring. The fixing ring is fixedly disposed on the right side of the outer surface of the chuck body. Multiple through rods are disposed through the fixing ring. An electromagnetic ring is fixedly disposed at the right end of each through rod, and a locking ring is fixedly disposed at the left end of each through rod.

[0010] Preferably, the retaining ring is made of stainless steel that can be magnetically attracted.

[0011] Preferably, the inner diameter of the locking ring is equal to the outer diameter of the chuck body, and when the electromagnetic ring is adsorbed on the fixed ring, the locking ring is located on the left side of the inclined surface at the right end of the clamping block.

[0012] Preferably, a positioning component is installed on the right side of the outer surface of the chuck body. The positioning component includes a positioning groove formed on the right side of the outer surface of the chuck body, and a positioning block is fixedly disposed in the positioning groove by a spring.

[0013] Preferably, the positioning block is trapezoidal in shape with the thickness gradually decreasing on the right side. When the spring is in its natural extended state, the right end of the positioning block is completely inside the positioning groove, and the left end of the positioning block extends out of the positioning groove. When the spring is in its maximum compressed state, the positioning block is completely embedded in the positioning groove.

[0014] Preferably, when the electromagnetic ring is adsorbed onto the left side surface of the fixed ring, the right side surface of the electromagnetic ring and the left side surface of the positioning block are on the same vertical plane.

[0015] 1. This utility model, by incorporating a clamping block and a magnetic locking assembly, allows for easy drill bit replacement. By disconnecting the power supply to the electromagnetic ring and moving it to the right, the electromagnetic ring, via a through rod, moves the locking ring to the right until it is positioned to the right of the clamping block. The spring force then moves the clamping block to the outside of the drill bit mounting slot, releasing the clamping block and facilitating the removal of the replacement drill bit from the slot. The replacement drill bit is then placed into the slot. Moving the electromagnetic ring to the left, the electromagnetic ring, via the through rod, moves the locking ring to the left, pressing against the inclined surface of the clamping block until it is embedded in the drill bit mounting slot, clamping and fixing the drill bit within. Energizing the electromagnetic ring causes it to adhere to the right surface of the fixing ring, locking the clamping block in place and thus locking the drill bit. Drill bit replacement is simple and convenient.

[0016] 2. This utility model, by setting a positioning block, ensures that when the electromagnetic ring moves to the right and is adsorbed onto the fixed ring, the locking ring presses the clamping block into the drill bit mounting groove, and the clamping block locks and fixes the drill bit. At this time, the right surface of the electromagnetic ring and the left surface of the positioning block are on the same vertical plane. The positioning block positions the electromagnetic ring, preventing the electromagnetic ring from falling off the fixed ring due to unstable adsorption, which would cause the locking ring to fail to position the clamping block and lock the drill bit, thus further ensuring the stability of the drill bit after installation.

[0024] like Figures 1-5As shown, an embodiment of this utility model provides a magnetic chuck device for quick drill bit replacement, including a chuck body 1, a drill bit mounting groove 101, a through groove 102, a connecting component, and clamping blocks 2. The drill bit mounting groove 101 is provided in the center of the left end of the chuck body 1. Through grooves 102 are provided in the four directions of the drill bit mounting groove 101 (up, down, inside, and outside). Multiple clamping blocks 2 are connected to the right end of the drill bit mounting groove 101 through the connecting component. The connecting assembly includes a fixed plate 3 fixed inside the right end of the drill bit mounting slot 101. Guide rods 301 are fixedly provided on the four sides of the fixed plate 3 in the inner, outer, upper and lower directions. A through hole 201 is provided through the right end of the clamping block 2. The guide rods 301 pass through the through hole 201. A sleeve spring 302 is fixedly provided between the clamping block 2 and the fixed plate 3. A magnetic locking assembly is installed on the right side of the outer surface of the chuck body 1 to drive the clamping block 2 to move towards the drill bit mounting slot 101 and clamp the drill bit installed in the drill bit mounting slot 101.

[0025] In this embodiment, the clamping block 2 matches the through slot 102, and the clamping block 2 can move along the through slot 102 to the side closer to the drill bit mounting slot 101 and away from the drill bit mounting slot 101.

[0026] In this embodiment, the clamping block 2 is in the shape of a trapezoid with a gradually decreasing thickness at the right end, and when the sleeve spring 302 is in a naturally extended state, the right end of the clamping block 2 is completely inside the through groove 102, and the left end of the clamping block 2 extends out of the through groove 102.

[0027] In this embodiment, the fixing plate 3 is made of magnetic material. The fixing plate 3 can attract and install the drill bit in the drill bit mounting slot 101, ensuring the stability of the drill bit installation.

[0028] In this embodiment, the magnetic locking assembly includes a fixing ring 4, a through rod 401, an electromagnetic ring 402, and a locking ring 403. The fixing ring 4 is fixedly disposed on the right side of the outer surface of the chuck body 1. Multiple through rods 401 are disposed through the fixing ring 4. An electromagnetic ring 402 is fixedly disposed at the right end of the through rod 401, and a locking ring 403 is fixedly disposed at the left end of the through rod 401.

[0029] In this embodiment, the fixing ring 4 is made of stainless steel that can be magnetically attracted, which facilitates the electromagnetic ring 402 to attract the fixing ring 4.

[0030] In this embodiment, the inner diameter of the locking ring 403 is equal to the outer diameter of the chuck body 1, and when the electromagnetic ring 402 is adsorbed on the fixed ring 4, the locking ring 403 is located on the left side of the inclined surface at the right end of the clamping block 2, which facilitates the locking ring 403 being pressed into the drill bit mounting groove 101 to achieve the effect of locking the drill bit.

[0031] With the clamping block 2 and magnetic locking assembly, when changing the drill bit, the power to the electromagnetic ring 402 is disconnected, and then the electromagnetic ring 402 is moved to the right. The electromagnetic ring 402 drives the locking ring 403 to move to the right through the through rod 401 until the locking ring 403 is on the right side of the clamping block 2. The elastic force of the sleeve spring 302 moves the clamping block 2 to the outside of the drill bit mounting slot 101. At this time, the clamping block 2 releases its grip on the drill bit, making it easy to remove the drill bit to be replaced from the drill bit mounting slot 101. Then, the drill bit to be replaced is put into the drill bit mounting slot. Within the mounting slot 101, the electromagnetic ring 402 is moved to the left. The electromagnetic ring 402, through the through rod 401, drives the locking ring 403 to move to the left. The locking ring 403 presses against the inclined surface of the clamping block 2 until the clamping block 2 is embedded in the drill bit mounting slot 101, clamping and fixing the drill bit in the slot 101. The electromagnetic ring 402 is then energized, causing it to adhere to the right side surface of the fixing ring 4, thus locking the position of the clamping block 2 and locking the drill bit. Drill bit replacement is simple and convenient.

[0032] In this embodiment, a positioning component is installed on the right side of the outer surface of the chuck body 1. The positioning component includes a positioning groove 103 formed on the right side of the outer surface of the chuck body 1. A positioning block 5 is fixedly disposed in the positioning groove 103 by a spring 501.

[0033] In this embodiment, the positioning block 5 is a trapezoidal shape with the thickness gradually decreasing on the right side. When the spring 501 is in a naturally extended state, the right end of the positioning block 5 is completely inside the positioning groove 103, and the left end of the positioning block 5 extends out of the positioning groove 103. When the spring 501 is in a maximum compressed state, the positioning block 5 is completely embedded in the positioning groove 103.

[0034] In this embodiment, when the electromagnetic ring 402 is adsorbed onto the left side surface of the fixed ring 4, the right side surface of the electromagnetic ring 402 and the left side surface of the positioning block 5 are on the same vertical plane.

[0035] With the positioning block 5 in place, when the electromagnetic ring 402 moves to the right and is attracted to the fixed ring 4, the locking ring 403 presses the clamping block 2 into the drill bit mounting groove 101, and the clamping block 2 locks and fixes the drill bit. At this time, the right surface of the electromagnetic ring 402 and the left surface of the positioning block 5 are on the same vertical plane. The positioning block 5 positions the electromagnetic ring 402 to prevent the electromagnetic ring 402 from falling off the fixed ring 4 due to unstable attraction, which would cause the locking ring 403 to be unable to position the clamping block 2 and lock the drill bit, thus further ensuring the stability of the drill bit after installation.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
