Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of drill bit stripping device technology, and more specifically, to a stripping device for drill bit production. Background Technology

[0002] In the field of machining, various types of drill rods are often used for hole machining of parts. In the production and processing of drill rods, in order to ensure the cutting performance and service life of the drill bit, it is often necessary to use a grinding device to grind the drill bit.

[0003] Currently, existing drill bits require one end to be smaller in diameter than the other during grinding. The method is to remove the drill bit after grinding one end to stop further grinding. Existing devices use electromagnets to achieve drill bit ejection using electromagnetic force. However, the short-stroke electromagnet brake generates a large impact force when it quickly engages, which can easily cause the fixing bolts to loosen, leading to the failure of the ejection device. At the same time, excessive inertial force can cause the equipment bridge to vibrate violently, affecting processing accuracy and stability, and resulting in low safety. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a stripping device for drill bit production, which solves the technical problems of low efficiency and poor grinding quality of manual hand-held grinding in the prior art.

[0005] According to one aspect, at least one embodiment of this disclosure provides a stripping device for drill bit production, comprising a plate, a vertical plate, connecting bolts, a pneumatic cylinder, a connector, a connecting rod, a limiting mechanism, a horizontal plate, a guide block, a connecting screw, a fixing frame, a threaded cylinder, a nut, an extension plate, a proximity switch, a fixing frame, a hinge, an opening and closing frame, and fixing screws. The vertical plate is fixedly mounted to the front end of the plate via connecting bolts. A limiting groove is formed on the vertical plate, and a limiting mechanism is slidably disposed within the limiting groove. The limiting mechanism is fixedly connected to the connecting rod. A pneumatic cylinder is fixedly mounted to the upper end of the plate. The piston rod of the pneumatic cylinder passes through the plate and the lower end of the piston rod is connected to the connecting rod through a connector. The rear end of the vertical plate is fixedly connected to a horizontal plate and a fixing frame. The rear end of the fixing frame is provided with a guide block. The guide block is fixedly connected to the fixing frame through a connecting screw. The lower end of the guide block is fixedly connected to a threaded cylinder. The threaded cylinder passes through the horizontal plate and is screwed with four nuts. Two of the nuts are respectively located at the upper and lower ends where the threaded cylinder passes through the horizontal plate. The lower end of the connecting rod passes through the guide block and the threaded cylinder and the lowest end is fixedly connected to a knock-down rod.

[0006] For example, in at least one embodiment of the present disclosure, a stripping device for drill bit production is provided, wherein the connecting member includes a cylinder and a first fixing bolt. The upper and lower ends of the cylinder are symmetrically provided with mounting holes, and one side of each mounting hole is spirally connected with a first fixing bolt. The lower end of the pneumatic cylinder piston rod and the top end of the connecting rod are both interference-fitted and installed in the cylinder, and the connection is fixed by the first fixing bolt.

[0007] For example, at least one embodiment of the present disclosure provides a stripping device for drill bit production, wherein the limiting mechanism includes a connecting ring, a second fixing bolt, and a limiting rod. The second fixing bolt is spirally connected to one side of the connecting ring, and the limiting rod is fixedly connected to the other side. The limiting rod is slidably disposed in a limiting groove, and the connecting ring is sleeved on the connecting rod and fixed by the second fixing bolt.

[0008] For example, in at least one embodiment of the present disclosure, an extension plate is fixedly connected to the inner side of the lower end of the vertical plate, and a proximity switch is fixedly installed at the lower end of the extension plate.

[0019] like Figures 1-6 As shown, a stripping device for drill bit production according to an embodiment of this disclosure is illustrated, comprising a plate 1, a vertical plate 2, connecting bolts 3, a pneumatic cylinder 4, a connector 5, a connecting rod 6, a limiting mechanism 7, a horizontal plate 8, a guide block 9, a connecting screw 10, a fixing frame 11, a threaded cylinder 12, a nut 13, an extension plate 14, a proximity switch 15, a fixing frame 16, a hinge 17, an opening and closing frame 18, and fixing screws 19. The front end of the plate 1 is fixedly mounted with the vertical plate 2 by the connecting bolts 3. A limiting groove 201 is formed on the vertical plate 2, and a limiting mechanism 7 is slidably arranged in the limiting groove 201. The limiting mechanism 7 is fixedly connected to the connecting rod 6. The upper end of the plate 1 is fixedly mounted with... The plate is equipped with a pneumatic cylinder 4. The piston rod of the pneumatic cylinder 4 passes through the plate 1 and the lower end of the piston rod is connected to the connecting rod 6 through the connector 5. The rear end of the vertical plate 2 is fixedly connected to a horizontal plate 8 and a fixing frame 11. The rear end of the fixing frame 11 is provided with a guide block 9. The guide block 9 is fixedly connected to the fixing frame 11 through a connecting screw 10. The lower end of the guide block 9 is fixedly connected to a threaded cylinder 12. The threaded cylinder 12 passes through the horizontal plate 8 and is screwed with four nuts 13. Two of the nuts 13 are respectively located at the upper and lower ends of the threaded cylinder 12 where it passes through the horizontal plate 8. The lower end of the connecting rod 6 passes through the guide block 9 and the threaded cylinder 12 and is fixedly connected to a knocking rod at the bottom.

[0020] In this embodiment, the piston rod of the pneumatic cylinder 4 is fixedly connected to the connecting rod 6 by the connector 5. By extending and retracting the piston rod of the pneumatic cylinder 4, the connecting rod 6 is pushed to perform the action of dropping and resetting the drill bit. This replaces the existing electromagnet technology for material removal devices. During operation, it will not generate large impact force and inertial force, and there is no problem of demagnetization of magnetic materials affecting the reliability of drill bit material removal. It has better stability and safety.

[0021] In this embodiment, each component adopts a detachable connection structure design, which facilitates the disassembly and installation of the device, and makes it easy to replace or repair a damaged component during use.

[0022] When further installing the unloading device, a through hole slightly larger than the diameter of the threaded cylinder 12 is pre-drilled on the equipment bridge. After unscrewing the nut 13 at the bottom of the threaded cylinder 12, the lower end of the threaded cylinder 12 passes through the through hole. Then, the unscrewed nut 13 is tightened upwards until it can no longer be turned. The unloading device can then be installed and fixed on the equipment bridge, thus achieving the installation and fixation of the device.

[0023] The connecting component 5 includes a cylinder 501 and a first fixing bolt 502. The upper and lower ends of the cylinder 501 are symmetrically provided with mounting holes, and the first fixing bolt 502 is spirally connected to one side of each mounting hole. The lower end of the piston rod of the pneumatic cylinder 4 and the top end of the connecting rod 6 are both interference-fitted and installed in the cylinder 501, and the connection is fixed by the first fixing bolt 502.

[0024] The structure of the connecting piece 5 facilitates the installation and disassembly of the piston rod of the pneumatic cylinder 4 and the connecting rod 6, improving assembly efficiency and facilitating subsequent maintenance. The interference fit and the fixing method of the first fixing bolt 502 ensure that the connection between the piston rod of the pneumatic cylinder 4 and the connecting rod 6 has sufficient strength and stability.

[0025] The limiting mechanism 7 includes a connecting ring 701, a second fixing bolt 702, and a limiting rod 703. The second fixing bolt 702 is spirally connected to one side of the connecting ring 701, and the limiting rod 703 is fixedly connected to the other side. The limiting rod 703 is slidably disposed in the limiting groove 201. The connecting ring 701 is sleeved on the connecting rod 6 and fixed by the second fixing bolt 702.

[0026] An extension plate 14 is fixedly connected to the inner side of the lower end of the vertical plate 2, and a proximity switch 15 is fixedly installed at the lower end of the extension plate 14.

[0027] The connecting ring 701 of the limiting mechanism 7 is fixedly installed on the connecting rod 6 by the second fixing bolt 702, while the limiting rod 703 is slidably arranged in the limiting groove 201. The limiting groove 201 and the limiting rod 703 cooperate to limit the stroke of the pneumatic cylinder 4 pushing the connecting rod 6. The proximity switch 15 installed at the lower end of the extension plate 14 enables precise movement and limiting of the stripping rod, which has good safety.

[0028] like Figures 5-6 As shown, it illustrates a stripping device for drill bit production in one embodiment of the present disclosure. A fixing frame 16 is provided at the rear end of the plate 1. The fixing frame 16 is fixedly connected to the rear end of the plate 1 by two fixing screws 19. The lower end of the fixing frame 16 is engaged with the bottom end of the horizontal plate 8 by a bent edge.

[0029] The two sides of the fixed frame 16 are movably connected to the opening and closing frame 18 via hinges 17. The front end of the opening and closing frame 18 is fixedly connected to the plate 1 via fixing screws 19. The fixed frame 16, hinges 17 and opening and closing frame 18 constitute the protective outer frame. In this embodiment, the opening and closing frame 18 is movably connected to both sides of the fixed frame 16. During use, the fixing screws 19 that fix the opening and closing frame 18 can be unscrewed, so that the opening and closing frame 18 can be flipped outward around the hinge 17 to open and close, thereby exposing the internal protective structure. This makes it easier to observe the operation of the disengagement device during use and facilitates inspection and maintenance.
