Description

Technical Field

[0001] This application relates to the field of drill bit processing, and in particular to an integrated milling machine. Background Technology

[0002] With the development of Chinese society, my country's industry has become increasingly developed, which has led to an increase in the demand for industrial products, of which drill bits are one.

[0003] A drill bit typically consists of a shaft with spiral grooves on its outer wall to guide drill cuttings out. The shaft end also has a chip removal groove to guide drill cuttings into the spiral grooves. The end wall of the shaft end also features an angled surface to improve cutting efficiency. The spiral grooves are usually machined using a milling cutter on a milling machine. After milling, the shaft is removed and placed on a cutting machine. The chip removal grooves and the angled surface on the shaft end are typically machined using the cutting machine.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: the rod body processing requires processing by two machines, a milling machine and a cutting machine, to be formed, and workers need to transport the rod body processed by the milling machine to the cutting machine, which makes the rod body processing process cumbersome. Summary of the Invention

[0005] To improve the cumbersome processing flow of the rod body, this application provides an integrated milling machine.

[0006] This application provides an integrated milling machine, which adopts the following technical solution:

[0007] An integrated milling machine includes: a milling mechanism for clamping the rod of a drill bit and controlling its rotation and sliding; a cutter shaft slide mechanism located on one side of the milling mechanism for machining a spiral groove on the rod; a corner-cutting mechanism located on one side of the milling mechanism for machining a chip removal groove and a bevel at the end of the rod; a clamping and cutting mechanism located on one side of the milling mechanism for clamping the rod held on the milling mechanism and moving the rod to the corner-cutting mechanism; and a base on which the milling mechanism, cutter shaft slide mechanism, corner-cutting mechanism, and clamping and cutting mechanism are all mounted.

[0008] By adopting the above technical solution, when the rod needs to be processed, the rod is first clamped by the milling mechanism and moved to the cutter shaft slide mechanism. Then, the rod is processed by the cutter shaft slide mechanism. The milling mechanism then rotates and slides the rod simultaneously to process the spiral groove. The clamping and cutting mechanism then clamps the rod processed by the milling mechanism and transports it to the corner cutting mechanism. The corner cutting mechanism processes the chip removal groove and the bevel at the end of the rod. This reduces the steps of transporting the rod between the corner cutting mechanism and the cutter shaft slide mechanism and the angle correction of the rod, shortening the process and greatly improving the efficiency of rod processing.

[0009] Optionally, the milling mechanism includes a milling base and a milling clamp that rotates through the milling base. The milling clamp has a rod inlet hole for inserting a rod. An elastic clamping block for holding the rod is provided on the inner wall of the end of the rod inlet hole. A milling rotation drive is provided outside the milling clamp, which drives the milling clamp to rotate. A milling sliding seat is provided under the milling base, and a milling sliding drive is provided on the base, which drives the milling base to slide along the extension direction of the spiral groove.

[0010] By adopting the above technical solution, the rod is placed into the milling groove clamping cylinder through the rod inlet hole, and then the rod is clamped by the elastic clamping block. The milling groove rotation drive and the milling groove sliding drive are used to make the milling groove clamping cylinder rotate and slide, thereby controlling the rod to process a spiral groove extending along the length of the rod on the cutter shaft slide plate mechanism. The operation is convenient and quick.

[0011] Optionally, a milling groove clamping cylinder is fitted with a milling groove pressure plate wheel, the milling groove pressure plate wheel is rotatably connected to the milling groove base, and a milling groove angle driving component is provided on the milling groove sliding seat, the milling groove angle driving component is used to control the rotation of the milling groove pressure plate wheel.

[0012] By adopting the above technical solution, the milling groove pressure plate wheel is controlled to rotate on the milling groove base by the milling groove angle drive component, thereby controlling the rotation of the milling groove clamping cylinder, and then adjusting the angle formed between the rod held by the milling groove clamping cylinder and the cutter shaft slide mechanism, thereby adjusting the pattern of the spiral groove, which is convenient and quick to operate.

[0013] Optionally, the milling mechanism further includes a milling fixture seat, which has a milling fixture slot. The milling fixture slot has the same milling elastic element on its inner wall. The milling elastic element clamps the rod body on the inner wall of the milling fixture slot.

[0014] By adopting the above technical solution, the rod is clamped by the inner walls of the milling fixture with the slots facing each other, so that the milling fixture seat and the milling clamping cylinder jointly clamp the rod, which improves the stability of the rod and reduces the probability of the rod's rotation and sliding being affected when the tool shaft slide mechanism processes the rod, thus improving the stability of the rod during processing.

[0015] Optionally, the cutter shaft slide mechanism includes a lifting seat, on which a milling lifting head slides. A disc cutter for machining spiral grooves on the rod rotates on the milling lifting head. A milling rotation drive is provided on the milling lifting head, and the output shaft of the milling rotation drive is used to drive the disc cutter to rotate. The milling lifting drive is provided on the lifting seat, and the milling lifting drive is used to drive the milling groove lifting head to rise and fall.

[0016] By adopting the above technical solution, the milling rotary drive component drives the disc cutter to rotate, thereby processing the rod. The milling lifting drive component controls the lifting of the disc cutter, so that the disc cutter rises and disengages from the rod after processing, reducing the probability of the disc cutter accidentally cutting the rod, improving the processing stability between the disc cutter and the rod, and facilitating the disc cutter's cutting of the rod and disengagement from the rod.

[0017] Optionally, the clamping and cutting mechanism includes a clamping transition pad, a cutting clamp seat that slides on the clamping transition pad, a movable cutting clamp for clamping the rod that slides on the cutting clamp seat, a cutting slider for controlling the sliding of the movable cutting clamp that slides on the cutting clamp seat, a cutting clamp driving component that is also provided on the cutting clamp seat, the output shaft of the cutting clamp driving component that controls the sliding of the cutting slider, a clamp sliding driving component that is provided on the clamping transition pad, and the output shaft of the clamp sliding driving component that controls the cutting clamp seat to slide toward or away from the milling groove clamping cylinder.

[0018] By adopting the above technical solution, the sliding of the cutting fixture seat is controlled by the fixture sliding drive component, causing the cutting fixture seat to slide towards the milling chuck. Then, the cutting fixture drive component controls the sliding of the cutting slider, thereby causing the moving cutting clamp to slide and clamp the machined rod held by the milling chuck. Then, the milling chuck is controlled to disengage from the rod. At this time, the cutting fixture seat can control the displacement of the rod, and at the same time, the clamping of the rod plays a limiting role in the rotation and sliding of the rod, improving the stability of the rod and facilitating the transportation of the rod. This makes it difficult for the angle of the rod to change after transportation, thereby reducing the steps of calibrating the angle of the rod and shortening the processing flow of the rod.

[0019] Optionally, the clamping and cutting mechanism further includes a clamping slider plate that slides on the clamping transition pad. The clamping slider plate is provided with a cutting clamping cylinder for clamping the rod. The cutting clamping cylinder is provided with a cutting rotation drive member for driving the cutting clamping cylinder to rotate. The clamping slider plate is also provided with a cutting sliding drive member for controlling the cutting clamping cylinder to slide towards or away from the cutting mechanism. The clamping transition pad is provided with a clamping slider drive member, and the output shaft of the clamping slider drive member is used to control the clamping slider plate to slide towards or away from the cutting mechanism.

[0020] By adopting the above technical solution, the rod body transported by the cutting clamp is clamped by the cutting clamp, and the sliding of the cutting clamp is controlled by the cutting sliding drive component, thereby transporting the rod body to the corner cutting mechanism. The corner cutting mechanism processes the chip removal groove at the end of the rod body, and the outer wall of the end of the rod body is cut at an angle by the cooperation of the corner cutting mechanism and the rotation of the cutting clamp, which facilitates the processing of the end of the rod body.

[0021] Optionally, the base is provided with a cutting slider plate, and the cutting slider plate is provided with a pad sliding drive component. The output shaft of the pad sliding drive component is used to control the fixture transition pad to slide towards or away from the cutting mechanism. The base is also provided with a cutting slider drive component, and the output shaft of the cutting slider drive component is used to control the cutting slider plate to slide towards or away from the milling base.

[0022] By adopting the above technical solution, the sliding of the fixture transition pad is controlled by the pad sliding drive component, and the sliding of the cutting slider plate is controlled by the cutting slider drive component. These components work together to assist the sliding of the cutting fixture seat and the cutting clamping cylinder set on the fixture transition pad, making the sliding of the cutting fixture seat and the cutting clamping cylinder more convenient, faster and more accurate. This improves the efficiency of the cutting fixture seat in holding the rod and the efficiency of the cutting clamping cylinder in transporting the rod to the corner cutting mechanism.

[0023] Optionally, the corner-cutting mechanism includes a cutting machine for machining chip grooves on the rod, the cutting machine being equipped with a deburring blade, a milling cutter disc for machining bevels on the end of the rod being provided on the base, and a milling cutter drive for controlling the rotation of the milling cutter disc being provided on the base.

[0024] By adopting the above technical solution, a chip removal groove is processed on the end of the rod using a cutting machine, burrs generated after processing on the end of the rod using a razor blade, and a bevel is processed on the end of the rod using a milling cutter. The processing flow is fast and smooth, improving the processing efficiency of the rod.

[0025] Optionally, the cutting fixture seat is provided with a fixture groove, and the number of cutting movable clamps is at least two and they are symmetrically installed on the inner walls opposite to each other in the fixture groove. A first guide slope is provided on the side walls of adjacent cutting movable clamps facing away from each other, and a second guide slope is provided on the side walls of the cutting sliders facing each other. The first guide slope and the second guide slope correspond one-to-one and abut against each other. When the cutting slider slides towards the cutting movable clamp, the adjacent cutting movable clamps will slide towards each other. A cutting elastic element for resetting is provided between adjacent cutting movable clamps.

[0026] By adopting the above technical solution, the cutting slider is controlled to slide closer to the cutting movable clamp by the cutting clamp drive component. The second guide slope on the cutting slider abuts against the first guide slope on the cutting movable clamp, so that as the cutting slider slides, the adjacent cutting movable clamps slide closer to each other, thereby clamping the rod located between the adjacent cutting movable clamps. The squeezing clamp between the cutting movable clamps also limits the rotation and sliding of the rod, so that after the spiral groove is processed, the rod can be directly processed for the chip removal groove and the slope without the need for rod angle calibration, reducing the processing steps of the rod and improving the processing efficiency of the rod.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When machining the rod body, the rod body is first clamped by the milling mechanism and moved to the cutter shaft slide mechanism. Then, the cutter shaft slide mechanism is used to machine the rod body. The milling mechanism then rotates and slides the rod body simultaneously to machine a spiral groove. The clamping and cutting mechanism then clamps the rod body that has been machined by the milling mechanism and transports it to the corner cutting mechanism. The corner cutting mechanism then machines chip removal grooves and bevels at the ends of the rod body. This reduces the steps of transporting the rod body between the corner cutting mechanism and the cutter shaft slide mechanism and the angle correction of the rod body, shortening the process and greatly improving the efficiency of rod body machining.

[0029] 2. The sliding of the cutting fixture seat is controlled by the sliding drive component of the fixture, causing the cutting fixture seat to slide towards the milling chuck. Then, the cutting fixture drive component controls the sliding of the cutting slider, which in turn slides to clamp the machined rod held by the milling chuck. Then, the milling chuck is controlled to disengage from the rod. At this time, the cutting fixture seat can control the displacement of the rod. At the same time, by clamping the rod, it limits the rotation and sliding of the rod, improving the stability of the rod and facilitating the transportation of the rod. This makes it difficult for the angle of the rod to change after transportation, thereby reducing the steps of calibrating the angle of the rod and shortening the processing flow of the rod.
