Description

Technical Field

[0001] The present invention relates to the technical field of machining, and more specifically, it relates to a tooling for installing a machining drill bit. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. The machines required for machining include digital display milling machines, digital display lathes, drill presses, electric discharge machines, machining centers, laser welding machines, wire cutting machines, grinding machines, precision lathes, etc. Precision parts can be machined, such as turning, milling, planing, grinding, etc. In machining, drilling with a drilling device is a common machining method. Drilling is the machining of holes on solid materials and various parts with a drill bit. Except for a part completed by machine tools such as lathes, boring machines, and milling machines, a large part is completed by fitters using drill presses and drilling tools (drill bits, reamers, etc.).

[0003] Currently, for the tooling for installing machining drill bits on the market, there are the following technical problems when installing and disassembling drill bit parts: When the existing tooling for installing machining drill bits installs and disassembles drill bit parts, it mostly installs and disassembles by clamping and engaging with a chuck. This easily causes the circumferential slipping of the engaged drill bit parts during later use, and the installation and disassembly processes are relatively cumbersome, making it inconvenient for workers to quickly replace drill bit parts, bringing certain inconvenience to the maintenance process of workers. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a tooling for installing a machining drill bit that can replace the original fixed connection method of the chuck, simplifies the installation and disassembly processes in the whole process, and avoids the circumferential slipping phenomenon inside the drill bit parts during later use due to the fixed connection method of the chuck.

A rocker is fixed to the outer wall of the rotating cylinder and slidably engaged with the socket column. An L-shaped pressing column is fixed to the outer wall of the rotating cylinder and abuts against the rectangular column. An arc-shaped spring is fixed between the rocker and the baffle.

[0011] The present invention is further configured as: two symmetrical limiting grooves are formed in the inner wall of the socket hole, and both opposite end faces of the socket column are provided with a round top.

[0012] Two symmetrical limiting rails are fixed to the circumferential side of the socket column, and the two limiting rails are respectively slidably engaged with the two limiting grooves.

[0013] The present invention is further configured as: two symmetrical connecting plates are fixed to one side of the H-shaped plate below the rocker, and positioning holes are respectively formed through the tops of the two connecting plates.

[0014] A plurality of threaded columns are fixed to the inner bottom of the socket cylinder, and a rotating nut is threadedly connected to the circumferential sides of the plurality of threaded columns. The positioning holes are inserted and engaged with the threaded columns.

A hexagonal groove extending upward is formed at the bottom of the anti-rotation column, and a circular socket hole inserted and engaged with the threaded column is formed at the top of the hexagonal groove. The hexagonal groove is clamped and engaged with the rotating nut.

[0016] The present invention is further configured as: a machine tool spindle is fixed to the opposite other end of the conical socket table.

[0023] Through the elastic reset process of the compressed elastic spring, the plugging posts slidably fitted through the bottom of the extension plate are driven to slide in the reverse direction, so that the tops of the plugging posts gradually separate from the plugging holes, driving the rocker fixedly connected to the outer peripheral side of the rotating cylinder to be gradually pressed down, and combining with the synchronous elastic reset process of a number of compressed arc-shaped springs, driving a number of L-shaped pressing columns to perform a reverse lifting action, providing a reverse force for the rectangular column plugged and fixed between a number of positioning members, so that the drill bit finally separates from the spindle member. In the whole process, the detachable process between the spindle member and the drill bit is simplified, replacing the original method of fixing and disassembling the chuck, and facilitating the staff to quickly replace the drill bit in a timely manner.

[0024] In the present invention, through the anti-rotation column fixed at the end of the conical insertion table, the hexagonal groove opened at the bottom of the anti-rotation column, and the circular insertion hole opened at the top inside the hexagonal groove, the anti-rotation column is clamped and inserted and fixed with the rotating nut and the threaded column, further positioning and fixing the rotating nut. Synchronously, the first thread track provided on the inner wall of the rotating sleeve and the second thread track provided on the outer wall of the rotating sleeve are respectively threadedly rotated and connected to the first thread groove and the second thread groove, further clamping and locking the positioned component fixed by insertion, preventing the internal components from loosening during the high-speed rotation process of the tooling in the later use process, and avoiding affecting the later use process.

Specifically, it includes a spindle assembly 1, and a drill bit assembly 2 is inserted and installed at the end of the spindle assembly 1; the spindle assembly 1 includes a spindle part 3 and a fastener 4 threadedly connected to the spindle part 3, and the drill bit assembly 2 includes a drill bit part 5 inserted and fixed on the spindle part 3 and several positioning parts 6 inserted and fixed inside the drill bit part 5; the spindle part 3 includes a conical insertion table 301, a rectangular column 302 is fixed at the end of the conical insertion table 301, and insertion holes 303 are formed through the end of the conical insertion table 301 in a circumferential and integral arrangement, and several insertion holes 303 are respectively inserted and fixed with several positioning parts 6; the drill bit part 5 includes an insertion cylinder 501 inserted and fixed with the conical insertion table 301, and several L-shaped positioning plates 502 are fixed at the inner bottom of the insertion cylinder 501, and adjacent L-shaped positioning plates 502 are slidably matched with the positioning parts 6; the positioning part 6 includes an H-shaped plate 601 slidably matched between adjacent L-shaped positioning plates 502, a rectangular groove 602 extending upward is formed at the bottom of the H-shaped plate 601, a baffle 603 is fixed on the inner wall of the rectangular groove 602, an extension plate 604 is fixed at the top of the H-shaped plate 601, and an insertion column 605 inserted and matched with the insertion hole 303 is slidably penetrated at the bottom of the extension plate 604; a positioning ring 606 is fixed on the circumferential side of the insertion column 605 below the extension plate 604, and an elastic spring 607 sleeved on the insertion column 605 is fixed between the positioning ring 606 and the extension plate 604. A rotating cylinder 608 is rotatably matched on the inner wall of the rectangular groove 602 below the baffle 603. A rocker 609 slidably matched with the insertion column 605 is fixed on the outer wall of the rotating cylinder 608, an L-shaped pressing column 610 mutually attached to the rectangular column 302 is fixed on the outer wall of the rotating cylinder 608, and an arc-shaped spring 611 is fixed between the rocker 609 and the baffle 603.

[0041] The specific application of the first embodiment is as follows: Before this tooling is used, through the sliding plug-in fit between the rectangular column 302 fixed at the end of the conical plug-in table 301 and several positioning members 6, a squeezing force is gradually generated on the outer top of several L-shaped pressing columns 610 by the rectangular column 302 fixed at the end of the conical plug-in table 301, so that the rotating cylinder 608 rotatably fitted on the inner wall of the rectangular groove 602 below the baffle 603 rotates, compresses the arc-shaped spring 611 fixedly connected between the rocker 609 and the baffle 603, drives the rocker 609 fixed on the outer peripheral side of the rotating cylinder 608 to gradually perform a tilting action, and provides an upward sliding force for the plug-in column 605 slidably fitted through the extension plate 604, driving the elastic spring 607 fixedly connected between the positioning ring 606 and the extension plate 604 to be compressed synchronously, so that the outer bottom of several L-shaped pressing columns 610 gradually approaches the inner bottom of the plug-in cylinder 501, and synchronously makes the top of the plug-in column 605 gradually inserted into the interior of the plug-in hole 303, thus completing the slow plug-in fixation between the drill bit part 5 and the main shaft part 3. After the slow plug-in fixation is completed, the fastener 4 threadedly rotatably connected to the main shaft part 3 and the drill bit part 5 is rotated synchronously, so that the fastener 4 gradually moves forward on the main shaft part 3 and the drill bit part 5 and gradually approaches the interior of the plug-in cylinder 501 in the drill bit part 5, replacing the original clamping chuck fixed connection method, simplifying the installation method in the whole process, and avoiding the phenomenon of circumferential slippage inside the drill bit part 5 due to the clamping chuck fixed connection method during its later use; When it is necessary to disassemble and replace the drill bit part 5 after long-term use, first reverse-rotate the fastener 4 threadedly rotatably connected to the main shaft part 3 and the drill bit part 5, so that the fastener 4 gradually moves backward on the main shaft part 3 and the drill bit part 5 and gradually moves away from the interior of the plug-in cylinder 501 in the drill bit part 5 until the fastener 4 gradually separates from the drill bit part 5. At this time, the compressed elastic spring 607 gradually starts to perform elastic reset, drives the plug-in column 605 slidably fitted through the bottom of the extension plate 604 to slide backward, and thus makes the top of the plug-in column 605 gradually separate from the plug-in hole 303, so that the rocker 609 fixed on the outer peripheral side of the rotating cylinder 608 is gradually pressed down. When the rocker 609 fixed on the outer peripheral side of the rotating cylinder 608 is gradually pressed down, the compressed several arc-shaped springs 611 perform elastic reset synchronously, and thus drive several L-shaped pressing columns 610 to perform a reverse lifting action synchronously, providing a reverse force for the rectangular column 302 plug-in fixed between several positioning members 6, so that the drill bit part 5 is finally separated from the main shaft part 3. In the whole process, the detachable process between the main shaft part 3 and the drill bit part 5 is simplified, replacing the original clamping chuck fixed disassembly method, which is convenient for the staff to quickly replace the drill bit part 5 in time.

Subsequently, through the threaded rotation connection between the rotating nut 504 and the threaded column 503, the bottom of the rotating nut 504 is attached to the top of the connecting plate 613, thereby completing the insertion and installation and fixation of the entire positioning member 6.
