Description

Automatic production line for machining disc-shaped workpieces

Technical Field

The invention relates to the field of machining, in particular to an automatic production line for machining a disc-shaped workpiece.

Background

At present, in view of the relatively high automation degree of the automatic production line, the processing precision and the processing efficiency of the workpiece are continuously improved, and naturally, the automatic production line is widely applied to the field of machining, so that the improvement of the automatic production line in the field of machining is particularly necessary.

Taking a brake disc as an example, not only the center of the brake disc has a central cavity, and both ends of the brake disc are usually high-precision smooth surfaces provided with a plurality of regularly distributed round holes, but also the side surfaces of the brake disc are provided with a plurality of regularly distributed cavities.

The existing automatic production line for processing the brake disc can effectively improve the processing efficiency of the brake disc to a certain degree, but has a plurality of defects. For example, the spindle and the tool rest of the existing automatic production line for machining brake discs may be unreasonably arranged and mounted, which results in long machining time and low machining precision, and thus the brake discs are low in machining efficiency and machining precision. In addition, the brake disc may be difficult to install and maintain, occupy a large area, and affect the rapid processing of the brake disc or lengthen the transmission route of the brake disc due to the complex and even unreasonable structural design of the turnover device and the material channel, which all affect the processing efficiency and the processing precision of the brake disc.

Therefore, how to improve the processing precision and the processing efficiency of the disc-shaped workpiece is a technical problem to be solved urgently by those skilled in the art.

Compared with the background art, the automatic production line for processing the disc-shaped workpiece comprises an upper lathe bed, a lower lathe bed, a first double-station tool rest, a second double-station tool rest, a first intermittent feeding device, a second intermittent feeding device, a first integral main shaft and a second integral main shaft, wherein the first integral main shaft and the second integral main shaft are provided with integral main shaft boxes; the first support slide rail and the second support slide rail are arranged on one side, close to the first integral main shaft, of the upper bed body and are perpendicular to the central axis of the first integral main shaft; the servo turnover device is arranged on the lower lathe bed, and the top of the servo turnover device is provided with an elastic conical positioning block for installing and positioning a disc-shaped workpiece; and the camera identification device is respectively arranged at the tail ends of the first integral main shaft and the second integral main shaft and is used for automatically identifying batch codes of the disc-shaped workpieces clamped by the first integral main shaft and the second integral main shaft. The first support slide rail is arranged above the second support slide rail in parallel, and the vertical distance from the first support slide rail to the first integral spindle is greater than the vertical distance from the second support slide rail to the first integral spindle; and the bottom of the first intermittent feeding device or the bottom of the second intermittent feeding device is respectively provided with a material separating lifting frame which is arranged on the lower lathe bed and used for separating the disc-shaped workpiece from moving.

Because the first integral spindle and the second integral spindle are provided with the integral spindle box, the original separately-installed sliding plate and the original spindle box are installed in an integrated mode by the integral spindle box, the two original parts are changed into one part, gaps between the spindle box and the guide rail lead screw system and the original sliding plate are eliminated, meanwhile, the machining force arm is reduced by reducing the center height of the spindle, and the integral spindle box is better in shock resistance in the transmission process, so that the machining rigidity of the integral spindle box is improved. Naturally, the machine tool comprising the integral main spindle box has better rigidity, thereby improving the processing precision of the disc-shaped workpiece processed by the machine tool.

And because the top of the servo turnover device is provided with an elastic cone-shaped positioning block for supporting and positioning the disc-shaped workpiece, the original turnover tray is replaced. During machining, only the disc-shaped workpiece to be machined is arranged on the elastic conical positioning block, so that two functions of supporting and positioning can be realized, on one hand, the disc-shaped workpiece is fixed more stably and positioned more accurately, and the machining precision of the disc-shaped workpiece is higher; on the other hand, the size range of the disc-shaped workpiece which can be processed by the servo turnover device is enlarged, the application range is widened, the limitation of the disc-shaped size can be avoided to a certain extent, repeated clamping and carrying of the disc-shaped workpiece are avoided, the time for replacing the tool clamp and carrying is saved, and the processing efficiency of the disc-shaped workpiece is improved. In addition, because the servo turning device is driven by the servo motor, the original belt drive is avoided being utilized for speed reduction, the occupied area is reduced, the moving line of the disc-shaped workpiece is shortened, the transmission process is more stable, the vibration and the fault are reduced, the processing time of the disc-shaped workpiece is shortened, the fault rate is reduced, and the processing efficiency and the processing precision of the disc-shaped workpiece are improved.

And because the camera identification device is arranged at the tail ends of the first integral main shaft and the second integral main shaft, and the characteristics of the camera are combined, the camera can clearly capture the image information of the bottom of the workpiece, and identify the specific position of the batch code on each workpiece to be detected, so that manual identification is replaced, the labor intensity of operators is reduced, and the processing efficiency is improved. In addition, due to the fact that along with the existing technological development, the image processing device is mostly combined with the automation technology, the automation degree of related equipment is improved by the aid of the image processing technology, personnel participation is further reduced, and the machining efficiency of the disc-shaped workpiece is further improved.

And because the first supporting slide rail is arranged above the second supporting slide rail in parallel, and the vertical distance from the first supporting slide rail to the first integral main shaft is greater than that from the second supporting slide rail to the first integral main shaft, the rear sides of the first integral main shaft and the second integral main shaft simultaneously bear two acting forces which are respectively perpendicular to the central axes of the first and second integral main shafts, and the moment arm of the acting force positioned at the upper part is greater than that of the acting force positioned at the lower part, so that the first supporting slide rail is changed from original coplanarity to non-coplanarity, the first integral main shaft and the second integral main shaft are effectively prevented from being forwardly inclined in the working process, the integral processing rigidity of the equipment is improved, and the processing precision of the disc-shaped workpiece is improved.

And because the material separating lifting frame replaces the original front movable stop block and the original rear movable stop block, the structures of the first intermittent feeding device and the second intermittent feeding device become simple, the installation and the maintenance are convenient, the installation and the maintenance time is effectively shortened, the working intensity of the installation and the maintenance is reduced, and the improvement of the processing efficiency of the disc-shaped workpiece is facilitated.

Therefore, the automatic production line for processing the disc-shaped workpiece provided by the invention can effectively improve the processing efficiency and the processing precision of the disc-shaped workpiece.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific examples.

Referring to fig. 1, fig. 1 is a schematic axial view of an automatic production line for processing disc-shaped workpieces according to an embodiment of the present invention.

In this embodiment, the disc-shaped workpiece may be a brake disc, but of course, other kinds of disc-shaped workpieces are also possible, and are not limited thereto.

The embodiment of the invention discloses an automatic production line for processing a disc-shaped workpiece, which comprises a lower lathe bed 1, an upper lathe bed 2, a first double-station tool rest 31, a second double-station tool rest 32, an integral spindle box 40, a first integral spindle 41, a second integral spindle 42, a first supporting slide rail 51, a second supporting slide rail 52, a servo turning device 6, a first intermittent feeding device 71, a second intermittent feeding device 72, a material isolating lifting frame 8 and a camera recognition device.

Based on the angle shown in fig. 1, it is assumed that the left and right ends of the upper bed 1 are left and right, respectively, and accordingly, the upper and lower sides of the upper bed 1 are upper and lower, respectively. In addition, a direction parallel to the first integrated spindle 41 or the second integrated spindle 42 is referred to as a Z-axis, and accordingly, a direction perpendicular to the Z-axis and passing through the upper bed 2 is referred to as a Y-axis, and a direction perpendicular to the Z-axis and parallel to the upper bed 2 is referred to as an X-axis.

The lower bed 1 is horizontally disposed, and the upper bed 2 is vertically installed at the rear side of the lower bed 1. The lower bed body 1 and the upper bed body 2 integrally form a bed body of the machine tool and are mainly used for supporting various functional components.

The first double-station tool rest 31 and the second double-station tool rest 32 are respectively installed at the left end and the right end of the lower bed body 1 and are mainly used for respectively machining brake discs clamped at the tail ends of the first integral main shaft 41 and the second integral main shaft 42. In this embodiment, the first two-position tool post 31 includes a tool post 311 and a gang drill 312, and the second two-position tool post 32 includes a boring tool post 321 and a double finishing tool post 322.

The turning tool seat 311 is located below the first integral spindle 41 and fixed at the left end of the lower bed 1. The tool holder 311 is usually provided with a turning tool for turning a disc brake clamped to the end of the first integrated spindle 41. The drilling jig discharging frame 312 is fixed on one side of the lathe tool seat 311 far away from the left end of the lower lathe bed, a plurality of tool rests used for fixing drill bits are installed at the top of the drilling jig discharging frame, the drill bits installed in the tool rests generally vertically upwards, and the surfaces of brake discs are conveniently drilled simultaneously, so that the machining efficiency and the machining precision are improved. It should be noted that, since the first integrated main spindle 41 is mounted on the upper bed 2 through the first support slide 51, the first integrated main spindle 41 can only move along the Z-axis or the X-axis, and obviously, the tool post 311 and the gang drill 312 are overlapped with each other along the central axis of the X-axis, so as to avoid the misalignment in the Y-axis direction as much as possible, so as not to affect the machining precision.

Similarly, the boring holder 321 is located directly below the second integrated spindle 42 and is fixed to the right end of the lower bed 1. The boring cutter holder 321 is mainly used for installing a boring cutter for boring a brake disc fixed at the end of the second integrated spindle 42, and in this embodiment, the boring cutter installed on the boring cutter holder 321 is vertically upward and is generally used for boring a circular hole distributed on the end face of the brake disc. The double-precision turning tool rest 322 is fixed on one side of the boring tool seat 321 far away from the right end of the lower lathe bed 1 and is mainly used for turning and installing the upper end face and the lower end face of the brake disc of the second integral main shaft 42. In view of the same, since the second integrated spindle 42 is mounted on the upper bed 2 via the second support slide rail 52, the second integrated spindle 42 can only move along the Z-axis or the X-axis, and obviously, the central axes of the boring holder 321 and the double finishing tool post 322 coincide with each other, so as to avoid the misalignment in the Y-axis direction as much as possible, so as not to affect the machining accuracy.

Referring to fig. 2, fig. 2 is a schematic cross-sectional structure view of the double-precision turning tool holder in fig. 1.

In this particular embodiment, the double finishing tool holder 322 includes a tool support, a fixed tool seat, a moving tool seat 3223, a transmission, a moving guard 3227, and a fixed guard 3228.

The fixed tool apron is usually fixed to a tool support, while the fixed tool holder is fixed to the lower bed 1, and is mainly used for fixing a turning tool and supporting the turning tool to turn a workpiece. The fixed tool post includes an upper tool post 3221 and a lower tool post 3222, wherein the upper tool post 3221 is naturally fixed to the tool support for mounting a turning tool, and it is noted that a tool tip of the turning tool mounted on the upper tool post 3221 faces downward so as to cooperate with an upper tool of the movable tool post 3223 to process a brake disc at the same time. The lower tool apron 3222 is also fixed to the tool holder, and is located below the upper tool apron 3221, for installing a turning tool, and similarly, a tool tip of the turning tool installed on the lower turning tool 12 is upward, so that the lower tool that cooperates with the movable tool apron 3223 simultaneously processes a brake disc. In addition, the upper tool seat 3221 and the lower tool seat 3222 are distributed in a step shape. In this embodiment, the length of the upper tool seat 3221 is less than that of the lower tool seat 3222, and of course, the length of the upper tool seat 3221 may be greater than that of the lower tool seat 3222, and the specific dimension is determined according to the specific situation. The stepped portions of the upper tool apron 3221 and the lower tool apron 3222 are not only beneficial to matching with the movable tool apron 3223 to realize processing of different shaft diameters, but also more beneficial to retracting of the movable tool apron 3223.

A moving seat 3223 is generally attached to the tool support and is parallel to the fixed seat for moving the tool relative to the fixed seat. The movable tool holder 3223 generally moves between the upper tool holder 3221 and the lower tool holder 3222, an upper turning tool with a tool tip upward matched with the upper tool holder 3221 is arranged at the top of the movable tool holder 3223, and a lower turning tool with a tool tip downward matched with the lower tool holder 3222 is arranged at the bottom of the movable tool holder 3223. The movable protection plate 3227 and the transmission device are connected into a whole by a base of the movable tool apron 3223 through bolts. Obviously, the moving distance of the moving knife seat 3223 is determined by the transmission distance of the transmission device.

The transmission device is connected between the tool holder and the movable tool holder 3223, and is used for driving the movable tool holder 3223 to move. In this embodiment, the upper tool seat 3221, the lower tool seat 3222, and the movable tool seat 3223 are distributed in parallel in the vertical direction, and the transmission device naturally drives the movable tool seat 3223 to move in the vertical direction. The transmission device comprises a sliding plate 3224 and a guide rail pair, wherein the sliding plate 3224 is connected with the moving protection plate 3227, and can naturally drive the moving tool apron 3223 connected with the moving protection plate 3227 to move; the track pair is connected to the sliding plate 3224, and generally includes a bearing member and a moving member, and specifically, the sliding plate 3224 is clamped at two sides of the moving member of the track pair and moves on the bearing member along with the moving member to drive the sliding plate 3224 to move. In general, there are many types of guide rail pairs, and in this embodiment, the guide rail pair specifically includes a ball screw pair 3225 and a slider 3226, wherein a screw nut of the ball screw pair 3225 is used as a moving member, connected to the sliding plate 3224, and moves on a guide screw, and since the screw usually converts a rotary motion into a linear motion, the screw can be used to drive the sliding plate 3224 to perform the linear motion. In order to move the moving part, the screw nut is generally provided with a servo motor at the end of the screw to provide power for the movement of the screw. In order to move the sliding plate 3224 in a predetermined direction and reduce the load applied to the ball screw assembly, a slider 3226 is disposed on one side of the sliding plate 3224, such that the sliding plate 3224 can move along a predetermined track on the slider 3226, and the other side of the slider 3226 is tightly fixed to the inner wall of the protective cover 4, such that the moving protection plate 3227 can be tightly pressed against the opening of the fixed protective cover 3228. Of course, other transmission devices capable of achieving the same function can be selected, and the purpose of the application can be achieved.

The moving protection plate 3227 is connected between the moving tool apron 3223 and the transmission device and covers the opening to seal the transmission device. In order to make the transmission device have better sealing performance, the movable protection plate 3227 is connected to the bottom of the movable tool apron 3223, and completely closes the opening of the fixed protection cover 3228, so that iron chips cannot enter the transmission device completely. Generally, the moving prevention plate 3227 may be a metal thin plate having a high strength, which is tightly pressed and fixed on the opening of the protection cover 3228. In order to tightly press the moving prevention plate 3227 against the fixed prevention cover 3228, the moving prevention plate 3227 is generally disposed on an outer surface of the fixed prevention cover 3228. It should be noted that, since the moving protection plate 3227 moves up and down on the opening of the fixed protection cover 3228 along with the moving tool apron 3223 under the driving of the transmission device connected thereto, the roughness accuracy of the contact surface between the moving protection plate 3227 and the fixed protection cover 3228 is high, so as to reduce friction during corresponding movement, and of course, a wear-resistant material may be coated on the contact surface, or a lubricant may be coated on the contact surface, so as to reduce friction of the contact surface, thereby achieving a better sealing effect. In addition, the distance from the edge of the opening of the fixed protective cover 3228 to the edge of the movable protective plate 3227 is greater than the distance moved by the driving device to drive the movable knife seat 3223, so that the movable protective plate 3227 can consistently cover the opening of the fixed protective cover 3228 in the moving process, and the sealing performance of the driving device is better.

The fixed protective cover 3228 is disposed around the driving device and fixed to the tool holder for isolating the driving device, wherein an opening is formed in a connection portion between the movable tool apron 3223 and the driving device by the fixed protective cover 3228 in order to enable the movable tool apron 3223 to cooperate with the fixed tool apron to achieve turning of the brake disc without affecting isolation of the fixed protective cover 3228 from the driving device. The opening generally conforms to the shape of the base of the movable blade holder 3223, and is typically a regular shape for ease of machining. The opening is preferably not too large in order to provide a better seal for the transmission. Generally, the stationary shield 3228 is a semi-open box with an opening at one side, which is typically welded from a plurality of thin metal plates to isolate all components of the transmission. Since the transmission precision and maintenance cost in the transmission are high, in order to prevent iron chips generated when the brake disc is turned from entering the transmission, it is necessary to protect the transmission with a fixed protective cover 3228.

Of course, the structure of the first and second dual-

position tool holders

31 and 32 and the type of tools to be mounted are not limited thereto, and other similar schemes are adopted and affect the achievement of the object of the present invention.

Referring to fig. 3, fig. 3 is a schematic structural diagram of the integral spindle head shown in fig. 1 of fig. 3.

The first and second

integral spindles

41 and 42 are respectively installed at the left and right ends of the upper bed 2, and have an integral spindle box 40 for mainly holding and transferring a brake disc. In this particular embodiment, the first unitary spindle 41 is arranged parallel to the second unitary spindle 42.

In this particular embodiment, the integral headstock 40 includes a bearing portion 401 and a slide portion 402. The bearing part 401 is mainly used for mounting a spindle, and the sliding part 402 is fixedly connected to the bottom of the bearing part 401 and is mainly used for mounting a lead screw.

The carriage 401 is a core part of the machine tool, and a spindle and other speed change devices are mounted therein. The carrier 401 generally comprises a cylindrical cavity for carrying the spindle and a bottom plate connected to the bottom of the cylindrical cavity for contacting the guide rail. In order to ensure sufficient rigidity of the cylindrical cavity, a plurality of reinforcing ribs are generally welded between the two sides of the cylindrical cavity and the bottom plate so as to improve the machining precision of the main shaft.

The sliding part 402 is fixed on the bottom surface of the bottom plate of the bearing part 401, the outer surface of the sliding part 402 is approximately square, and two sides of the bottom part are provided with chamfers. The inner cavity 21 for mounting the lead screw is arranged on the longitudinal length of the sliding part 402, and the sliding part 402 is equivalent to a sliding plate in the prior art to a certain extent, and is equivalent to integrating the original spindle box and the sliding plate into a whole, so that the structure of the spindle box is more compact.

The longitudinal central plane of the bearing part 401 coincides with the longitudinal central plane of the sliding part 402, which means that the axial central line of the spindle is on the longitudinal central plane of the sliding part 402, so as to prevent the spindle mounted on the bearing part 401 and the lead screw in the inner cavity 21 of the sliding part 402 from shifting in the horizontal direction, which causes the inclination of the spindle head on the horizontal plane due to uneven force applied to the left and right sides of the bearing part 401. The width of the bottom surface of the bearing part 401 is larger than that of the upper surface of the sliding part 402, so that the bottom surface of the bearing part 401 has enough space to directly contact with the guide rail, and the integral spindle box 40 moves more smoothly.

In addition, the axial center line of the cavity 21 of the slide portion 402 is on the longitudinal center plane of the slide portion 402, and the axial center line of the cavity 21 of the slide portion 402 is parallel to the axial center line of the spindle, so as to prevent the integral headstock 40 from being displaced in the horizontal or vertical direction with respect to the lead screw, resulting in tilting of the integral headstock 40. The bottom surface of the sliding part 402 is provided with a square notch communicated with the inner cavity 21 of the sliding part, so that a lead screw can be conveniently installed; the longitudinal central plane of the square notch coincides with the longitudinal central plane of the inner cavity 21 of the sliding part 402 for convenient processing; in addition, the width of the square notch should be smaller than the outer diameter of the nut of the screw rod, so that the sliding portion 402 can slide stably.

It should be noted that the inner cavity 21 of the sliding part 402 is in close contact with the outer surface of the nut of the screw, and there is no relative sliding, so that the screw drives the integral spindle box 40 to slide.

In addition, the present application further comprises a first pressure sensor disposed between the bearing part 401 and the guide rail and used for detecting the load between the bearing part 401 and the guide rail, a second pressure sensor disposed between the sliding part 402 and the lead screw and used for detecting the load between the sliding part 402 and the lead screw, and a control device connected with the first pressure sensor and the second pressure sensor and used for processing and displaying signals sent by the first pressure sensor and the second pressure sensor. When the pressure of the first pressure sensor received by the control device exceeds a preset threshold, the acting force of the bearing part 401 on the guide rail is too large, which indicates that the problems that the axial center line of the spindle on the bearing part 401 is not parallel to the upper surface of the guide rail 1, the bottom plate of the bearing part 401 is not flat, and the like exist; similarly, when the pressure of the second pressure sensor received by the control device exceeds the preset threshold, the acting force of the sliding portion 402 on the screw is too large, which indicates that the central axis of the inner cavity 21 of the sliding portion 402 is not parallel to the central axis of the screw, and the error of the cylindricity of the inner cavity of the sliding portion 402 is large. The abnormal contact between the carriage 401 and the guide rail and between the sliding part 402 and the lead screw due to design, mounting, wear, etc. can be displayed to the operator by the control device. Therefore, the signal fed back by the control device is timely adjusted in the process of assembling or maintaining the spindle box, and the processing precision of the disc-shaped workpiece is improved.
