Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and more specifically, to an annular part slitting device. In addition, the present invention also relates to a vertical lathe including the above annular part slitting device. Background Art

[0002] The slitting of multiple annular parts from one annular part is a common operation in machining. The traditional slitting operation of annular parts uses a special flat and elongated slitting tool. The annular part is fixed on the workbench of a vertical lathe, and the workbench drives the annular part to rotate. The tool feeds alternately in two paths (which is beneficial for chip removal and preventing tool jamming). After cutting through the entire wall thickness of the annular part, the annular part can be slit.

[0003] In this traditional annular part slitting method, the tool feeding speed cannot be increased during the annular cutting process, resulting in low slitting efficiency; Moreover, in traditional annular part slitting, the tool path cannot be a single cut to the end. Otherwise, chip accumulation and tool jamming are likely to occur, and two tool paths need to feed alternately, further reducing the efficiency; At the same time, the thickness of the traditional annular part slitting tool cannot be made very thin. Coupled with two tool paths, the slitting cut is relatively wide, and there is more material waste; For small annular parts, the sawing method can be used to improve the slitting efficiency. However, for large annular parts, there is still no better slitting method in the industry, and this low-efficiency slitting method is still purchased.

[0004] In the prior art, although there are devices that use a circular saw to perform horizontal feeding and cross-cutting for slitting annular parts, the feeding length of the circular saw mainly depends on the length and rigidity of the guide rail. Therefore, its actual feeding amount is limited, and it cannot meet the slitting requirements of various sizes of annular parts. Moreover, the individual manufacturing cost is relatively high, and the equipment usage range is also small.

[0005] In summary, how to solve the problems of low slitting efficiency of large annular parts and limited stroke and high cost of circular saw equipment is an urgent problem to be solved by those skilled in the art at present. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide an annular part slitting device that uses a circular saw blade to slit annular parts, which helps to improve efficiency and solve the problems of difficult chip removal and wide cut. At the same time, the circular saw blade is connected to the lathe tool bar through a mounting frame, and the existing vertical lathe is used for slitting annular parts, reducing costs and solving the problem of limited stroke of existing circular saw equipment.

[0007] Another purpose of the present invention is to provide a vertical lathe including the above annular part slitting device, which has the same technical features and can solve the same technical problems.

[0008] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0014] Preferably, a stepped shaft is coaxially arranged at the end of the power output shaft of the driving device, the circular saw blade is coaxially sleeved on the small-diameter part of the stepped shaft, and one end face of the circular saw blade abuts against the shaft shoulder of the stepped shaft. A fastening nut is threadedly engaged with the small-diameter end of the stepped shaft for abutting against the other end face of the circular saw blade.

[0019] Compared with the prior art, the ring part cutting device provided by the present invention has at least the following beneficial effects:

[0020] 1. By driving the circular saw blade to rotate through the driving device to cut the ring part, with the high rotational speed and relatively thin thickness of the circular saw blade, the cutting efficiency of the ring part is improved, and the problems of difficult chip removal and easy tool jamming are solved.

[0021] 2. The circular saw blade is directly connected to the lathe tool post by using the mounting frame, so there is no need to manufacture the guide rail required for the feeding of the circular saw blade, which reduces the cost. Moreover, by means of the original structure of the lathe, the ring part can rotate during the cutting process, so the circular saw blade only needs a relatively small feeding stroke to complete the cutting of the ring part, solving the problem that a super-large sawing machine is required for traditional sawing.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0027] The core of the present invention is to provide a ring part cutting device. Using a circular saw blade to cut ring parts helps improve efficiency and solve the problems of difficult chip removal and wide cutting edges. At the same time, the circular saw blade is connected to the lathe tool post through an installation frame, and an existing vertical lathe is used to cut ring parts, reducing costs and solving the problem of limited stroke of existing circular saw equipment.

[0028] Another core of the present invention is to provide a vertical lathe including the above ring part cutting device, which has the same technical features and can solve the same technical problems.

[0029] Please refer to Figure 1 , a ring part cutting device, comprising: A circular saw blade 4; A driving device 3, whose power output shaft is power-connected to the circular saw blade 4 for driving the circular saw blade 4 to rotate; An installation frame 1, which is relatively rotatably connected to the circular saw blade 4 and is relatively fixedly installed with the driving device 3; Wherein, a connecting mechanism for installing with a lathe tool post 8 is arranged in the installation frame 1.

[0030] As Figure 3 shown, the driving device 3 is used to drive the circular saw blade 4 to rotate at a high speed to cut the ring part. By using the high rotation speed of the circular saw blade 4, the cutting efficiency is effectively improved. At the same time, the thickness of the circular saw blade 4 at the edge position is usually greater than that at other positions, so the problems of the circular saw blade 4 being stuck and difficult chip removal can be effectively solved; at the same time, the circular saw blade 4 can cut to the bottom in one cut without taking two cutting paths, and the cutting efficiency is further improved;

[0031] Moreover, the thickness of the circular saw blade 4 is smaller than that of the existing cutting tool. When cutting the ring part, a narrower cutting edge can be obtained, so less raw material is wasted; Moreover, by connecting the circular saw blade 4 and the driving device 3 to the lathe tool bar 8 together through the mounting frame 1, when performing ring splitting, the ring is clamped in a vertical lathe. The lathe drives the ring to rotate, and the lathe tool bar 8 drives the circular saw blade 4 to perform feeding in the vertical or horizontal direction, realizing that the ring is split while rotating itself, that is, the feeding amount of the circular saw blade 4 only needs to be greater than the thickness of the ring to complete the splitting of the ring. Thus, the requirement for the feeding stroke of the circular saw blade 4 is reduced, there is no need to manufacture an oversized sawing machine, the splitting cost is reduced, and after separating the mounting frame 1 from the lathe tool bar 8, it does not affect the original functions of the lathe itself, and the overall use is relatively flexible.

[0032] Among them, the driving device 3 is preferably a device capable of generating high-speed rotary motion such as a motor or a hydraulic motor.

[0033] In some embodiments, the mounting frame 1 is of a frame structure. The driving device 3 is fixedly arranged inside the mounting frame 1, and a shaft hole 13 for positioning the driving device 3 and for the power output shaft of the driving device 3 to penetrate is arranged at one end of the mounting frame 1.

[0034] As Figure 2 shown, the mounting frame 1 is an integral frame structure, which wraps the driving device 3 inside, and fixes and positions the driving device 3, ensuring a relatively stable relative position relationship between the power output shaft of the driving device 3 and the lathe tool bar 8. At the same time, the mounting frame 1 wraps the driving device 3, which helps to achieve physical protection of the driving device 3; At the same time, a shaft hole 13 is arranged at the bottom of the mounting frame 1, so that the power output shaft of the driving device 3 can extend to the outside of the mounting frame 1. When setting the shaft hole 13, it can be designed according to the end structure of the driving device 3 to play a role in positioning the driving device 3. At the same time, a plurality of second screw holes 14 are arranged around the periphery of the shaft hole 13 for fixing the driving device 3 to the mounting frame 1 through bolts.

[0035] In some embodiments, the mounting frame 1 adopts a combined structure, that is, it includes a top plate, side plates and a bottom plate that are relatively fixedly connected, and the top plate, side plates and bottom plate jointly enclose a frame structure. Among them, a shaft hole 13 is arranged on the surface of the bottom plate, which can also achieve the same effect as above.

[0036] In some embodiments, a clamping plate 2 is fixedly connected to the other end of the mounting frame 1 through bolts, and the clamping plate 2 can be fixedly connected to the lathe tool bar 8 through bolts.

[0037] As Figure 1 and Figure 2 shown, a first screw hole 12 is arranged at the top of the mounting frame 1 for connecting the clamping plate 2 through bolts, and the clamping plate 2 can be directly clamped with the lathe tool bar 8, so that the connection and installation of the mounting frame 1 and the lathe tool bar 8 can be realized quickly and without damage.

[0038] In some embodiments, the clamping plate 2 is of a U-shaped structure and is arranged perpendicular to the outer end face of the mounting frame 1, and the middle arm of the clamping plate 2 is fixedly connected to the mounting frame 1 by bolts.

[0039] As Figure 1 and Figure 2 shown, the clamping plate 2 adopts a U-shaped structure, and its middle wall is directly fixedly connected to the first screw hole 12 at the top end of the mounting frame 1 by bolts. Moreover, since the clamping plate 2 is perpendicular to the outer end face of the mounting frame 1, the remaining two end arms of the clamping plate 2 can be directly clamped and fixed inside the lathe tool bar 8 to obtain a good connection relationship.

[0040] In some embodiments, the side wall of the mounting frame 1 is provided with a through weight reduction hole 11.

[0041] As Figure 2 shown, a plurality of weight reduction holes 11 are opened on the side wall of the mounting frame 1 to reduce the self-weight of the mounting frame 1 and realize the light weight of the equipment.

[0042] In some embodiments, the power output shaft of the driving device 3 is power-connected to the circular saw blade 4 through a speed change mechanism or direct drive, and the speed change mechanism is fixedly installed relative to the mounting frame 1.

[0043] When the torque of the driving device 3 is small, a gearbox can be selected to be added to the output shaft end to realize speed reduction and torque increase, so as to improve the cutting force and further ensure the cutting effect of the ring part;

[0044] In some embodiments, when the torque requirement for circular cutting is small, the driving device 3 can be directly connected to the circular saw blade 4 for driving, reducing the intermediate transmission components, reducing power loss, and reducing the equipment cost.

[0045] In some embodiments, a stepped shaft 5 is coaxially arranged at the end of the power output shaft of the driving device 3, the circular saw blade 4 is coaxially sleeved on the small-diameter part of the stepped shaft 5, and one end face of the circular saw blade 4 abuts against the shaft shoulder of the stepped shaft 5. A fastening nut 7 is threadedly engaged with the small-diameter end of the stepped shaft 5 for abutting against the other end face of the circular saw blade 4.

[0046] As Figure 2 shown, the circular saw blade 4 is installed through the stepped shaft 5 at the end of the output shaft of the driving device 3, further reducing the installation difficulty of the circular saw blade 4. At the same time, the circular saw blade 4 is fastened by the fastening nut 7 to ensure that the circular saw blade 4 and the stepped shaft 5 have a stable relative position relationship during the working process.

[0047] In some embodiments, a gasket 6 is arranged outside the stepped shaft 5 between the circular saw blade 4 and the fastening nut 7, and the gasket 6 is an elastic gasket.

[0048] By adding an elastic gasket between the circular saw blade 4 and the fastening nut 7, the loosening of the fastening nut 7 during the working process is effectively prevented, thereby ensuring the stable installation of the circular saw blade 4.

[0049] In some embodiments, a blind hole is provided at the large-diameter end of the stepped shaft 5. The blind hole is installed in interference fit with the power output shaft, and a through threaded hole is provided on the side wall of the blind hole. A fastening screw 51 for abutting against the outer peripheral wall of the power output shaft at the end is installed in the threaded hole.

[0050] A flat key for inhibiting the relative rotation between the stepped shaft 5 and the power output shaft is provided between the stepped shaft 5 and the power output shaft.

[0051] As Figure 2 shown, the blind hole provided at the end of the stepped shaft 5 itself is directly sleeved with the power output shaft of the driving device 3 in an interference fit manner. By adding a flat key, it is ensured that the two will not rotate relative to each other, and by adding a fastening screw 51, it is ensured that the two will not move axially, that is, the relative position stability of the stepped shaft 5 and the power output shaft of the driving device 3 is ensured.

[0052] In addition to the ring part cutting device disclosed in each of the above embodiments, the present invention also provides a vertical lathe including the above ring part cutting device. For the structures of other parts of the vertical lathe, reference may be made to the prior art and will not be elaborated herein.
