Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of numerical control lathe, in particular to a slant bed numerical control lathe with high operation stability. BACKGROUND

[0002] The slant bed numerical control lathe is a highly automated metal cutting machine tool, which is mainly used for machining various rotary parts, such as shafts, discs, sleeves and other parts. Due to its precision in machining, it is widely used in mechanical manufacturing, automobiles, aerospace, electronics and many other fields. Compared with traditional flat bed lathes, slant bed numerical control lathes have many advantages, of which the most obvious advantage is that due to its inclined structure, the generated chips are not easy to remain in the guide rail during turning, and the chips will naturally slide down the bed slope under the action of gravity, thereby reducing the wear of the guide rail and improving the service life and machining accuracy of the machine tool.

[0003] The slant bed numerical control lathe mainly consists of a bed, a clamping assembly, a tail tower assembly, a tool tower assembly, a multi-directional moving assembly and a numerical control system, etc. The clamping assembly and the tail tower assembly are located directly above the chip removal port of the bed, and the tool tower assembly and the multi-directional moving assembly are in an inclined state on the side. When the clamping assembly clamps the workpiece and rotates at high speed, the tail tower assembly will be tightly pressed against the other end of the workpiece according to the length of the workpiece, thereby enhancing the stability of the workpiece fixation. The tool tower assembly will be driven by the multi-directional moving assembly to perform complex and precise machining on the workpiece. The multi-directional moving assembly drives the tool tower assembly to move in the Z-axis, X-axis and Y-axis directions, thereby making the tool tower assembly more flexible and the workpiece more precise.

[0004] However, in order to prevent thermal deformation of the workpiece during machining, cold water or coolant is sprayed at the machining site for cooling. At this time, once the combination of chips and liquid splashes onto the bed slope, due to the viscosity and surface tension of the liquid, they will quickly adhere to the lathe and are not easy to naturally slide down. Currently, the slant bed numerical control lathe is equipped with telescopic inclined plates on the surface of each axial guide rail. On the one hand, the telescopic inclined plates can effectively reduce the splashing of chips into the guide rail; on the other hand, as the telescopic inclined plates continuously extend and retract, the part of the chips adhered to the surface of the telescopic inclined plates will be scraped off by the extrusion action between the telescopic inclined plates, so that the surface of the telescopic inclined plates is relatively clean and tidy.

[0005] However, it is inevitable that the high and low difference between the plates will exist in order to complete the telescopic operation, which will cause the upper layer plate to push the debris on the surface of the lower layer plate together, and due to the viscosity and surface tension of the liquid on the surface of the debris, part of the debris will be attached to the surface of the lower layer plate in a linear shape after being pushed by the upper layer plate (this situation often occurs on the telescopic inclined plate in the Z-axis direction due to the transverse telescopic design of the telescopic inclined plate in the Z-axis direction), and long-term accumulation will cause the adhesion layer to become thicker and more firmly adhered, and the later cleaning is very laborious, and too much debris will even seriously affect the stability and precision of the tool turret assembly operation. Although the hard scraper used to clean the debris can remove most of the attached debris, the hard scraper is difficult to adapt to the high and low difference between the plate joints, so that the lower telescopic inclined plate is blocked by the upper telescopic inclined plate and cannot be in full contact with the hard scraper, and the surface of the lower telescopic inclined plate still has debris, and the position of the tool turret assembly after each machining is different, that is, the length of the telescopic inclined plate is not fixed, and the hard scraper with fixed size is difficult to adapt to such changes, resulting in unsatisfactory scraping effect.

[0006] In view of the above problems, it is urgent to make innovative design on the basis of the original work-stable inclined bed numerical control lathe. SUMMARY

DETAILED DESCRIPTION

[0058] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0059] Please refer to Figures 1 to 10 The present application provides a technical solution: a slant bed numerical control lathe with high work stability, comprising a numerical control machine box 1, a placement table 4 fixed on the front of the numerical control machine box 1, and a telescopic slant plate movably arranged in the numerical control machine box 1, further comprising:

[0060] A hanging rail 2 fixed at the upper end in the numerical control machine box 1;

[0061] A scraping assembly driven by the weight of the workpiece to adaptively change the height difference and the extension width of the telescopic slant plate;

[0062] A material receiving assembly with flexible discharging function driven by the weight of the workpiece;

[0063] In the specific implementation, the numerical control machine box 1 is composed of a bed, a clamping assembly, a tail tower assembly, a tool tower assembly, a multi-directional moving assembly, a numerical control system and the like, and the layout and electrical connection relationship of each assembly are consistent with the prior art, which will not be described in detail herein. In addition, the "Z-axis direction", "X-axis direction" and "Y-axis direction" mentioned in the present application are also consistent with the axis direction of the prior art. In addition, it should be noted that the present application is commonly used for machining regular solid shafts, discs and the like, and such parts have a relatively heavy weight. Since the part to be turned often has a large number of turning parts, a large amount of waste is generated, and the finished workpiece still has a relatively heavy weight. The present application uses the weight of the workpiece to complete the flexible discharging and scraping of the waste.

[0064] The scraping assembly comprises a first sliding plate 6 slidingly arranged at the top end in the hanging rail 2, and an elastic water belt 5 fixed at the lower end of the first sliding plate 6 and expanding the surface to fully adhere to the telescopic slant plate through internal interference;

[0065] In the specific implementation, the elastic water belt 5 is made of PU material, which has high strength and tear resistance, and is not easy to be damaged by scraping with waste. In addition, the elastic water belt 5 is elastic, and the water injected in the elastic water belt 5 is in an interference state, so that the elastic water belt 5 is in an expanded state to fully adhere to the surface of the telescopic slant plate.

[0066] The material receiving assembly comprises a second sliding plate 8 slidingly arranged at the top end in the hanging rail 2, a material receiving plate 12 movably arranged above the chip removal opening of the numerical control machine box 1, and a suspension rail 3 fixed on the inner wall of the numerical control machine box 1 to adaptively change the track to rotate and discharge the material receiving plate 12.

[0067] In practical implementation, in the initial state, that is, when the receiving plate 12 is not affected by the downward pressure of the workpiece's own weight, the receiving plate 12 should be located below the clamping assembly, ready to receive the cut workpiece after processing and drop it onto the receiving plate 12. (See attached...) Figure 9 and attached Figure 10 As can be clearly seen, the upper end of the receiving plate 12 is designed as an arc plate, which can effectively reduce the risk of the workpiece rolling off after falling onto the receiving plate 12. Furthermore, when the receiving plate 12 is rotated and unloaded later, the workpiece can roll off the arc surface of the receiving plate 12 more smoothly.

[0068] The overhead rail 2 is suspended in the air inside the CNC machine housing 1 via a lifting rod;

[0069] In practice, the hoisting design of the overhead rail 2 ensures that the first slide plate 6 and the second slide plate 8 will not collide with the clamping components in the CNC machine housing 1 when they slide.

[0070] The hanging rail 2 is parallel to the telescopic inclined plate;

[0071] In practice, when the first slide plate 6 and the second slide plate 8 slide along the track of the hanging rail 2, it can be ensured that the movement trajectory of the elastic water belt 5 and the receiving plate 12 can conform to the telescopic inclined plate, especially the elastic water belt 5 can always remain in contact with the surface of the telescopic inclined plate.

[0072] The length of the hanging rail 2 is more than twice the length of the telescopic inclined plate.

[0073] In practice, the first slide plate 6 and the second slide plate 8 slide together inside the same set of hanging rails 2, which ensures that when the elastic water hose 5 slides to the end of the telescopic ramp, the second slide plate 8 will not detach from the hanging rails 2.

[0074] The top of the shelf 4 has an inner groove;

[0075] In specific implementation, as shown in the appendix Figure 3 As shown, when the receiving plate 12 is rotating and pouring material, it is flush with the top surface of the shaping wire 14, so that the workpiece can slide smoothly into the inner groove.

[0076] The inner groove and the upper surface of the receiving plate 12 are both covered with sponge pads;

[0077] In practice, the sponge pad prevents the workpiece from being damaged by excessive impact when it falls onto the receiving plate 12 and into the inner groove.

[0078] One end of the inner groove is inclined near the inside of the CNC machine housing 1.

[0079] In practice, when the workpiece enters the inner groove, it tends to slide automatically into the groove due to the influence of its inclined surface, which prevents the workpiece from rebounding and falling off due to the rebound force.

[0080] The upper end of the first sliding plate 6 and the second sliding plate 8 is fixed with a fixed plate 9;

[0081] In the specific implementation, the fixed plate 9 fixes the first sliding plate 6 and the second sliding plate 8, so that the receiving plate 12 can drive the first sliding plate 6 and the second sliding plate 8 to slide along the hanging rail 2 at the same time while moving under the weight of the workpiece.

[0082] One end of the fixed plate 9 and the inner wall of the numerical control machine box 1 are connected by a iron ring hook with a reset tension spring 13;

[0083] In the specific implementation, when the fixed plate 9 moves obliquely downward, the reset tension spring 13 can be stretched, and after the workpiece pouring is completed, the fixed plate 9 can be pulled back to the original position automatically under the rebound of the reset tension spring 13, so as to prepare for the next time of receiving material. It should be noted that a square groove with sufficient space should be provided in the numerical control machine box 1 corresponding to the position of the reset tension spring 13, so that the reset tension spring 13 will not be unnecessarily rubbed with the numerical control machine box 1 when it is stretched.

[0084] The distance between the first sliding plate 6 and the second sliding plate 8 is greater than the length of the telescopic inclined plate.

[0085] In the specific implementation, the sufficient space distance between the first sliding plate 6 and the second sliding plate 8 will not hinder the work of the whole device.

[0086] The scraping assembly further comprises a control spring 7 fixed at one end of the elastic water belt 5 and one side of the lower end of the first sliding plate 6;

[0087] In the specific implementation, the control spring 7 provides power for the rebound of one end of the elastic water belt 5, so that the extension length of the elastic water belt 5 can be more easily shortened.

[0088] The telescopic inclined plate is fixed with a limiting piece 10 on one side;

[0089] The limiting piece 10 is composed of an arc-shaped auxiliary plate and a round rod located at the center position of the arc-shaped auxiliary plate;

[0090] In the specific implementation, it should be noted that in the prior art, one end of the X-axis telescopic inclined plate is fixed with one of the plates in the Z-axis telescopic inclined plate, and the tool turret assembly is fixed on the surface of the X-axis telescopic inclined plate. In this way, the tool turret assembly can move along the X-axis, and the X-axis telescopic inclined plate can move along with the Z-axis telescopic inclined plate, so that the tool turret assembly can also move along the Z-axis. Under this premise, one end of the limiting piece 10 is fixed on the surface of the same plate in the Z-axis telescopic inclined plate at the same time as one end of the X-axis telescopic inclined plate, so that the limiting piece 10 will not move along the X-axis, but can move along the Z-axis.

[0091] One end of the elastic water hose 5 bends along the inner arc of the arc-shaped auxiliary plate and wraps around the round rod.

[0092] In practice, the surfaces of the arc-shaped auxiliary plate and the round rod are both polished, which reduces the friction between the elastic water hose 5 and the limiting member 10 when bending, making it easier to bend.

[0093] The inner wall of the elastic water hose 5 is evenly provided with several sets of shaped steel wires 14;

[0094] Several sets of shaping steel wires 14 are coaxially distributed on one side of the inner wall of the elastic water hose 5;

[0095] The length of the shaped steel wire 14 is the same as the length of the elastic water hose 5.

[0096] In practice, the shaped steel wire 14 provides a certain supporting force for the elastic water hose 5, preventing the half of the elastic water hose 5 that is not in contact with the telescopic inclined plate from expanding excessively. The addition of the shaped steel wire 14 also ensures that the elastic water hose 5 is not too soft and lacks the compressive force to the telescopic inclined plate. The other half of the elastic water hose 5 remains in an expanded state and is in close contact with the surface of the telescopic inclined plate.

[0097] The receiving assembly also includes a second slider 16 fixed on both sides of the receiving plate 12;

[0098] The second slider 16 consists of two parts: a rectangular plate and a sliding column fixed to one end of the rectangular plate.

[0099] The other end of the rectangular plate is fixedly connected to the side of the receiving plate 12.

[0100] In specific implementation, as shown in the appendix Figure 9 and attached Figure 10 As shown, there is a clear angle between the second slider 16 and the receiving plate 12. When the second slider 16 slides along the inside of another set of slide grooves in the suspension rail 3 and the inside of the side rail groove 17, the second slider 16 can be pulled obliquely upward when the trajectories of the two change, thereby causing the receiving plate 12 to be passively rotated to realize the unloading operation.

[0101] The bottom of the second skateboard 8 is fixed with a movable plate 11;

[0102] The lower end of the receiving plate 12 and the top end of the moving plate 11 are rotatably connected by a shaft column;

[0103] In practice, the receiving plate 12 can rotate independently, and the moving plate 11 is not affected by it.

[0104] A slider 15 is fixed on the other side of the movable plate 11.

[0105] Two sets of sliding grooves are provided on one side of the suspension rail 3;

[0106] One set of slides is compatible with slider 15;

[0107] One set of the sliding grooves is parallel to the telescopic inclined plate;

[0108] In the embodiment, the first sliding block 15 slides along one set of the sliding grooves, and the size of the sliding grooves is matched with that of the first sliding block 15, so that the moving plate 11 moves along the predetermined track, and the moving direction of the moving plate 11 is consistent with the moving direction of the elastic water belt 5, and the overall track operation mode is more in line with the requirements.

[0109] The other set of the sliding grooves is matched with the slide column in the second sliding block 16;

[0110] In the embodiment, the slide column slides in the other set of the sliding grooves, and the size of the sliding grooves is matched with that of the slide column.

[0111] One end of the other set of the sliding grooves is parallel to the telescopic inclined plate, and the other end of the other set of the sliding grooves is in the state of being bent upward and obliquely.

[0112] In the embodiment, as shown in the attached Figure 2 and the attached Figure 3 When the second sliding block 16 slides along the sliding grooves away from the placement table 4, the opening of the receiving plate 12 can be kept in the state of being vertically upward, and the workpiece in the receiving plate 12 is not easy to fall, and when the second sliding block 16 encounters the sliding grooves close to the placement table 4, the second sliding block 16 is passively rotated by the oblique upward traction of the sliding grooves, so as to realize the rotating and dumping operation of the receiving plate 12.

[0113] The inner wall of the numerical control machine box 1 is provided with a side rail groove 17;

[0114] The side rail groove 17 is parallel to the telescopic inclined plate;

[0115] The size of the side rail groove 17 is matched with that of the slide column in the second sliding block 16.

[0116] In the embodiment, the design of the side rail groove 17 makes the slide column in the other set of the second sliding block 16 slide along the inside of the side rail groove 17, so that the both ends of the receiving plate 12 are more stable when moving, and the track change of the side rail groove 17 is completely consistent with that of the other set of the sliding grooves in the suspension rail 3.

[0117] Working principle: when using the work stability high slant bed numerical control lathe, first, the power supply is connected to the whole device power supply, and the workpiece is processed, here the specific operation and programming mode are consistent with the existing mature technology, the present application does not make too much elaboration. During the processing, the position of the tool tower changes constantly, the limiting piece 10 will follow the X axis and the connecting plate position moves, that is, the connecting plate drives the moving direction of the limiting piece 10 and the telescopic inclined plate, when the distance between the tool tower and the clamping assembly is farther, the elastic water belt 5 is pulled by the limiting piece 10, and the extension length of the elastic water belt 5 increases, at the same time, the control spring 7 is stretched, when the distance between the tool tower and the clamping assembly is closer, under the action of the elastic water belt 5 and the telescopic inclined plate, the extension length of the elastic water belt 5 decreases, and the side of the elastic water belt 5 always keeps close to the surface of the telescopic inclined plate, and because of the expansion state of the elastic water belt 5, the elastic water belt 5 is close to the upper plate and the lower plate in the telescopic inclined plate, the workpiece is cut off by the tool after processing, or it is pushed out of the clamping assembly by the ejector, after the workpiece falls on the receiving plate 12, the receiving plate 12 is passively moved down under the influence of the weight of the workpiece, the two groups of No. 2 sliding blocks 16 drive the moving plate 11 to slide along the other group of sliding grooves and side rail grooves 17 inside the suspension rail 3, at the same time, the No. 1 sliding block 15 slides along one group of sliding grooves inside the suspension rail 3, the No. 2 sliding plate 8 slides along the inside of the hanging rail 2, the No. 2 sliding plate 8 pulls the No. 1 sliding plate 6 through the fixed plate 9, so that the No. 1 sliding plate 6 synchronously slides along the inside of the hanging rail 2, the reset tension spring 13 is stretched, the No. 1 sliding plate 6 drives the elastic water belt 5 to move along the surface of the telescopic inclined plate, and the waste attached to the surface of the inclined plate is pushed to the chip pocket, while the receiving plate 12 containing the workpiece is close to the placement table 4, the slide columns in the two groups of No. 2 sliding blocks 16 are simultaneously affected by the change of the track of the side rail groove 17 and the other group of sliding grooves in the suspension rail 3, and suddenly move to the oblique upper side, at the same time, the moving track of the moving plate 11 does not change, so that the No. 2 sliding block 16 drives the receiving plate 12 to rotate, so that the workpiece in the receiving plate 12 rolls into the placement table 4, after the workpiece leaves the receiving plate 12, the fixed plate 9 is pulled back to the original position under the rebound of the reset tension spring 13, the elastic water belt 5 and the receiving plate 12 also return to the original position.
