使用时将待抛光异型管件定位固定放置到工件定位座上,加工伺服电机带动连接盘按照伺服角度转动从而带动待抛光异型管件的外侧三面(顶面外侧、侧面外侧、底面外侧)分别与弹性抛光带接触进行抛光打磨,由于连接盘按照伺服角度带动着待抛光异型管件转动调位时,待抛光异型管件的运动会存在垂直于移动平台方向上的竖向位移(如说明书附图图1中B处箭头方向)分运动和于平行于移动平台方向上的横向位移(如说明书附图图1中A处箭头方向)分运动,“上端的前侧带轮越过放置在工件定位座上的异型管工件,位于移动平台上边且远离后侧带轮一侧;下端的前侧带轮不越过放置在工件定位座上的异型管工件,位于移动平台下边且靠近后侧带轮一侧”这个结构设置配合弹性抛光带的弹性变形能力,能很好的保证若仅存在竖向位移变化时始终保持工件与弹性抛光带的接触;为了使若仅存在横向位移移变化时始终保持工件与弹性抛光带的接触,我们设计了移动平台,平台位移调节机构能够驱动移动平台的水平横向移动。如说明书附图图1所示,当连接盘按照伺服角度带动着待抛光异型管件转动调位出现向后方向上的水平分位移时,为了保证始终保持工件与弹性抛光带的接触,平台位移调节机构能够驱动移动平台水平向前方向的横向移动,从而补偿待抛光异型管件向后方向上的水平分位移,同理,当连接盘按照伺服角度带动着待抛光异型管件转动调位出现向前方向上的水平分位移时,为了保证始终保持工件与弹性抛光带的接触,平台位移调节机构能够驱动移动平台水平向后方向的横向移动,从而补偿待抛光异型管件向前方向上的水平分位移。综上所述,待抛光异型管件在转动调位过程中竖向分位移和横向份位移上都能得到结构上的解决和补偿,以此保证工件始终保持与弹性抛光带的接触进行打磨抛光。通过系统控制平台位移调节机构的调节、加工伺服电机对连接盘的驱动、平移机构对抛光带装置的驱动三者的互相配合运行,能实现对异型管件的三面自动化抛光工作,真正实现异型管件的全自动化打磨抛光加工,不仅省时、省力、省工,而且全自动化机械控制使打磨抛光质量更好,大大降低了产品不合格率。When in use, the special-shaped pipe to be polished is positioned and fixed on the workpiece positioning seat, and the processing servo motor drives the connecting plate to rotate according to the servo angle, thereby driving the outer three sides of the special-shaped pipe to be polished (outside of the top surface, outside of the side surface, and outside of the bottom surface) respectively and elastic polishing When polishing and grinding with contact, since the connecting plate drives the special-shaped pipe to be polished to rotate and adjust the position according to the servo angle, the movement of the special-shaped pipe to be polished will have a vertical displacement perpendicular to the direction of the moving platform (such as the position B in Figure 1 of the accompanying drawing of the manual). The direction of the arrow) is divided into movement and the lateral displacement in the direction parallel to the moving platform (such as the direction of the arrow at A in Figure 1 of the accompanying drawings) is divided into movement, "the front side pulley of the upper end passes over the special-shaped pipe workpiece placed on the workpiece positioning seat. , located on the upper side of the mobile platform and away from the rear side pulley; the front side pulley at the lower end does not cross the special-shaped pipe workpiece placed on the workpiece positioning seat, and is located under the mobile platform and close to the rear side pulley. The elastic deformation ability of the elastic polishing belt can ensure that the workpiece is always in contact with the elastic polishing belt if there is only a vertical displacement change; in order to keep the workpiece in contact with the elastic polishing belt when there is only a lateral displacement change , we designed a mobile platform, and the platform displacement adjustment mechanism can drive the horizontal and lateral movement of the mobile platform. As shown in Figure 1 of the accompanying drawings, when the connecting plate drives the special-shaped pipe to be polished according to the servo angle to rotate and adjust the position to cause horizontal displacement in the backward direction, in order to ensure that the contact between the workpiece and the elastic polishing belt is always maintained, the platform displacement adjustment mechanism It can drive the horizontal movement of the moving platform in the horizontal forward direction, thereby compensating for the horizontal displacement of the special-shaped pipe to be polished in the backward direction. Similarly, when the connecting plate drives the rotating and positioning of the special-shaped pipe to be polished according to the servo angle, the level in the forward direction appears. During sub-displacement, in order to ensure that the workpiece and the elastic polishing belt are always in contact, the platform displacement adjustment mechanism can drive the horizontal movement of the moving platform in the horizontal backward direction, thereby compensating for the horizontal sub-displacement of the special-shaped pipe to be polished in the forward direction. To sum up, the vertical displacement and lateral displacement of the special-shaped pipe to be polished can be solved and compensated structurally during the rotation adjustment process, so as to ensure that the workpiece is always in contact with the elastic polishing belt for grinding and polishing. The system controls the adjustment of the platform displacement adjustment mechanism, the drive of the processing servo motor to the connecting plate, and the drive of the translation mechanism to the polishing belt device. Fully automatic grinding and polishing processing not only saves time, labor and labor, but also fully automatic mechanical control makes the grinding and polishing quality better and greatly reduces the product failure rate.

所述抛光带装置包括抛光伺服电机8、弹性抛光带9、主动带轮10和三个从动带轮,三个从动带轮包括一个后侧带轮13和两个前侧带轮14。所述滑座7上设有支撑柱15和电机座16;所述支撑柱15顶部设有带轮调节气缸17,所述带轮调节气缸17的活塞杆末端连接有弧形轮架18,两个所述前侧带轮14分别设置在弧形轮架18的两端,通过控制带轮调节气缸17的活塞杆伸缩实现对两个前侧带轮14的横向位移,从而将弹性抛光带9撑紧以用于后期打磨抛光。而且,还可以根据异形工件在横向上的宽度大小来调节带轮调节气缸17的活塞杆的伸出长度,因为不同型号的异形工件在横向上的宽度是不同的,这就需要对带轮调节气缸17的活塞杆的伸出长度进行调整,进而实现对两个前侧带轮14的横向调整以适应不同型号异形工件的加工需求。此外,之所以设置带轮调节气缸17,还是为了方便上下料考虑,一个异形工件加工完卸料时,需要将带轮调节气缸17的活塞杆收缩,从而将两个前侧带轮14向远离工件加工平台方向移动,同时移动平台2也在平台位移调节机构的控制下向远离抛光装置一侧回位到原点,这样一来使抛光完成的异形工件不会再与弹性抛光带9接触,且不会与弹性抛光带9的位置产生干涉。The polishing belt device includes a polishing servo motor 8 , an elastic polishing belt 9 , a driving pulley 10 and three driven pulleys. The three driven pulleys include a rear pulley 13 and two front pulleys 14 . The sliding seat 7 is provided with a support column 15 and a motor seat 16; the top of the support column 15 is provided with a pulley adjustment cylinder 17, and the end of the piston rod of the pulley adjustment cylinder 17 is connected with an arc wheel frame 18. The front pulleys 14 are respectively arranged at both ends of the arc wheel frame 18, and the lateral displacement of the two front pulleys 14 is realized by controlling the expansion and contraction of the piston rod of the pulley adjusting cylinder 17, so that the elastic polishing belt 9 Hold tight for later grinding and polishing. Moreover, the extension length of the piston rod of the pulley adjustment cylinder 17 can also be adjusted according to the width of the special-shaped workpiece in the lateral direction, because the width of the special-shaped workpiece of different types in the lateral direction is different, which requires the adjustment of the pulley. The extension length of the piston rod of the cylinder 17 is adjusted, thereby realizing the lateral adjustment of the two front pulleys 14 to meet the processing requirements of different types of special-shaped workpieces. In addition, the reason why the pulley adjusting cylinder 17 is provided is for the convenience of loading and unloading. When a special-shaped workpiece is processed and unloaded, the piston rod of the pulley adjusting cylinder 17 needs to be retracted, so that the two front pulleys 14 are moved away from each other. The workpiece processing platform moves in the direction, and at the same time, the moving platform 2 returns to the origin on the side away from the polishing device under the control of the platform displacement adjustment mechanism, so that the polished special-shaped workpiece will no longer be in contact with the elastic polishing belt 9, and There is no interference with the position of the elastic polishing belt 9 .

为了实现异形工件的三面打磨抛光,在进行打磨抛光过程中,要保持弧形轮架18的顶端前侧带轮14越过放置在工件定位座6上的异型管工件,位于移动平台2上边且远离后侧带轮13一侧;弧形轮架18的底端前侧带轮14不越过放置在工件定位座6上的异型管工件,位于移动平台2下边且靠近后侧带轮13一侧;所述抛光伺服电机8设置在电机座16上。抛光伺服电机8驱动主动带轮10的转动,主动带轮10的转动带动弹性抛光带9的移动,只有这种状态设置的两个前侧带轮14才能保持弹性抛光带9与异型管工件的三个待抛面在加工过程中始终保持打磨抛光接触。In order to realize the three-sided grinding and polishing of the special-shaped workpiece, during the grinding and polishing process, it is necessary to keep the top front side pulley 14 of the arc-shaped wheel frame 18 over the special-shaped pipe workpiece placed on the workpiece positioning seat 6, on the mobile platform 2 and away from it. The rear side pulley 13 side; the front side pulley 14 of the bottom end of the arc wheel frame 18 does not cross the special-shaped pipe workpiece placed on the workpiece positioning seat 6, and is located under the mobile platform 2 and is close to the rear side pulley 13 side; The polishing servo motor 8 is arranged on the motor base 16 . The polishing servo motor 8 drives the rotation of the driving pulley 10, and the rotation of the driving pulley 10 drives the movement of the elastic polishing belt 9. Only the two front side pulleys 14 set in this state can maintain the elastic polishing belt 9 and the special-shaped pipe workpiece. The three surfaces to be polished are always in grinding and polishing contact during processing.

为了实现待打磨抛光异形工件的自动化定位固定,在移动平台2上设有第一光电开关19,第一光电开关19的设置位置为:当待抛光异型管工件水平安放到工件定位座6上后,待抛光异型管工件的末端凸板末端遮挡第一光电开关19的光信号,从而触发电磁铁机构12通电。不放置待抛光异型管工件时工件定位座6不会遮挡第一光电开关19的光信号。这样一来,当待抛光异型管工件两端的末端凸板末端全部遮挡第一光电开关19的光信号时,就能使电磁铁机构12通电,从而使电磁铁机构12的铁芯两端带有磁性,从而对待抛光异型管工件进行通过磁力吸附定位固定。In order to realize the automatic positioning and fixing of the special-shaped workpiece to be polished, a first photoelectric switch 19 is provided on the mobile platform 2, and the setting position of the first photoelectric switch 19 is: when the workpiece to be polished is horizontally placed on the workpiece positioning seat 6 , the end of the end convex plate of the special-shaped tube workpiece to be polished blocks the light signal of the first photoelectric switch 19 , thereby triggering the electromagnet mechanism 12 to energize. When the workpiece of the special-shaped pipe to be polished is not placed, the workpiece positioning seat 6 will not block the light signal of the first photoelectric switch 19 . In this way, when the ends of the end protruding plates at both ends of the special-shaped pipe workpiece to be polished completely block the optical signal of the first photoelectric switch 19, the electromagnet mechanism 12 can be energized, so that the iron core of the electromagnet mechanism 12 has both ends. Magnetic, so that the workpiece to be polished special-shaped pipe is positioned and fixed by magnetic adsorption.

为了方便的对打磨抛光后的异型管工件进行自动化卸料,移动平台2上设有第二光电开关20,第二光电开关20的设置位置为:待抛光异型管工件抛光完成,通过加工伺服电机3转动将工件转移到远离抛光装置一侧后,抛光异型管工件两端的末端凸板末端全部遮挡第二光电开关20的光信号时,从而触发电磁铁机构12断电。再继续转动运行,使抛光后的异型管工件水平以下向下倾斜状态时,抛光后的异型管工件自动滑落。本装置在移动平台2一侧设有卸料板29。抛光后的异型管工件自动滑落至卸料板29上,进而从卸料板29上滑落至地面的盛料小车31上。In order to facilitate the automatic unloading of the polished special-shaped pipe workpiece, the mobile platform 2 is provided with a second photoelectric switch 20, and the setting position of the second photoelectric switch 20 is: after the polishing of the special-shaped pipe workpiece to be polished is completed, it is processed by the servo motor. 3. After the workpiece is rotated and transferred to the side away from the polishing device, when the ends of the end convex plates at both ends of the polished special-shaped pipe workpiece completely block the optical signal of the second photoelectric switch 20, the electromagnet mechanism 12 is triggered to power off. Continue to rotate and run, so that the polished special-shaped pipe workpiece automatically slides off when the polished special-shaped pipe workpiece is tilted downward below the level. The device is provided with a stripper plate 29 on one side of the moving platform 2 . The polished special-shaped pipe workpiece automatically slides down onto the unloading plate 29, and then slides down from the unloading plate 29 to the trolley 31 on the ground.

使用方法详解:Detailed explanation of usage:

使用时,首先将待抛光异型管件定位固定放置到工件定位座6上。方法如下:待抛光异型管件放置到非金属定位盘11上的工件定位座6上,待抛光异型管工件的末端凸板末端遮挡第一光电开关19的光信号,从而触发电磁铁机构12通电。从而使电磁铁机构12的铁芯两端带有磁性,从而对待抛光异型管工件进行通过磁力吸附定位固定。When in use, firstly, the special-shaped pipe to be polished is positioned and fixed on the workpiece positioning seat 6 . The method is as follows: the special-shaped pipe to be polished is placed on the workpiece positioning seat 6 on the non-metal positioning plate 11, and the end of the end convex plate of the workpiece to be polished is blocked from the light signal of the first photoelectric switch 19, thereby triggering the electromagnet mechanism 12 to energize. Therefore, both ends of the iron core of the electromagnet mechanism 12 are magnetic, so that the workpiece of the special-shaped pipe to be polished can be positioned and fixed by magnetic adsorption.

然后,调整两个前侧带轮14的位置,还有就是向靠近抛光装置方向进行移动平台2调位,以此来保证弹性抛光带9与待打磨抛光的异型管件存在更好的打磨抛光接触位置。方法如下:通过控制带轮调节气缸17的活塞杆伸缩实现对两个前侧带轮14的横向位移,从而将弹性抛光带9撑紧且向靠近工件加工平台一侧移动一小段距离。通过伺服气缸21通过控制活塞杆的伸缩从而带动移动平台2底面的连接块22移动,进而实现移动平台2的水平横向位移。Then, adjust the positions of the two front pulleys 14, and adjust the position of the moving platform 2 in the direction close to the polishing device, so as to ensure that the elastic polishing belt 9 has better polishing and polishing contact with the special-shaped pipe to be polished. Location. The method is as follows: by controlling the expansion and contraction of the piston rod of the pulley adjusting cylinder 17, the lateral displacement of the two front pulleys 14 is realized, so as to tighten the elastic polishing belt 9 and move a short distance to the side close to the workpiece processing platform. The connecting block 22 on the bottom surface of the mobile platform 2 is driven to move by the servo cylinder 21 by controlling the expansion and contraction of the piston rod, thereby realizing the horizontal and lateral displacement of the mobile platform 2 .

然后,加工伺服电机3、带动连接盘4按照伺服角度转动从而带动待抛光异型管件的外侧三面(顶面外侧、侧面外侧、底面外侧)分别与弹性抛光带9接触进行抛光打磨,由于连接盘4按照伺服角度带动着待抛光异型管件转动调位时,待抛光异型管件的运动会存在垂直于移动平台2方向上的竖向位移(如说明书附图图1中B处箭头方向)分运动和于平行于移动平台2方向上的横向位移(如说明书附图图1中A处箭头方向)分运动,“上端的前侧带轮14越过放置在工件定位座6上的异型管工件,位于移动平台2上边且远离后侧带轮13一侧;下端的前侧带轮14不越过放置在工件定位座6上的异型管工件,位于移动平台2下边且靠近后侧带轮13一侧”这个结构设置配合弹性抛光带9的弹性变形能力,能很好的保证若仅存在竖向位移变化时始终保持工件与弹性抛光带9的接触;为了使若仅存在横向位移移变化时始终保持工件与弹性抛光带9的接触,我们设计了移动平台2,平台位移调节机构能够驱动移动平台2的水平横向移动。如说明书附图图1所示,当连接盘4按照伺服角度带动着待抛光异型管件转动调位出现向后方向上的水平分位移时,为了保证始终保持工件与弹性抛光带9的接触,平台位移调节机构能够驱动移动平台2水平向前方向的横向移动,从而补偿待抛光异型管件向后方向上的水平分位移,同理,当连接盘4按照伺服角度带动着待抛光异型管件转动调位出现向前方向上的水平分位移时,为了保证始终保持工件与弹性抛光带9的接触,平台位移调节机构能够驱动移动平台2水平向后方向的横向移动,从而补偿待抛光异型管件向前方向上的水平分位移。综上所述,待抛光异型管件在转动调位过程中竖向分位移和横向份位移上都能得到结构上的解决和补偿,以此保证工件始终保持与弹性抛光带9的接触进行打磨抛光。打磨过程中,丝杆伺服电机25通过丝杠丝母传动机构来控制整个抛光带装置沿着传动丝杠27方向的平移从而对待抛光异型管件进行逐步打磨抛光。即通过系统控制平台位移调节机构的调节、加工伺服电机3对连接盘4的驱动、平移机构对抛光带装置的驱动三者的互相配合运行,实现对异型管件的三面自动化抛光工作,真正实现异型管件的全自动化打磨抛光加工,Then, the servo motor 3 is processed and the connecting plate 4 is driven to rotate according to the servo angle, thereby driving the three outer sides (outside of the top surface, outside of the side surface, and outside of the bottom surface) of the special-shaped pipe to be polished to contact the elastic polishing belt 9 respectively for polishing and polishing. When the special-shaped pipe to be polished is driven to rotate and adjust the position according to the servo angle, the movement of the special-shaped pipe to be polished will have a vertical displacement in the direction perpendicular to the moving platform 2 (such as the direction of the arrow at B in Figure 1 of the accompanying drawings) divided into movement and parallel. The lateral displacement in the direction of the moving platform 2 (such as the direction of the arrow at A in Figure 1 of the accompanying drawings) is divided into motion, "the front pulley 14 at the upper end crosses the special-shaped pipe workpiece placed on the workpiece positioning seat 6, and is located in the moving platform 2. The upper side is away from the side of the rear side pulley 13; the front side pulley 14 at the lower end does not cross the special-shaped pipe workpiece placed on the workpiece positioning seat 6, and is located under the mobile platform 2 and is close to the rear side pulley 13. This structure is provided With the elastic deformation ability of the elastic polishing belt 9, it can be well ensured that the workpiece and the elastic polishing belt 9 are always kept in contact if there is only a vertical displacement change; With the contact of 9, we designed the mobile platform 2, and the platform displacement adjustment mechanism can drive the horizontal and lateral movement of the mobile platform 2. As shown in FIG. 1 of the accompanying drawings, when the connecting plate 4 drives the special-shaped pipe to be polished according to the servo angle to rotate and adjust the position to cause a horizontal displacement in the backward direction, in order to ensure that the workpiece and the elastic polishing belt 9 are always kept in contact, the platform is displaced. The adjustment mechanism can drive the horizontal movement of the moving platform 2 in the horizontal forward direction, thereby compensating for the horizontal displacement of the special-shaped pipe to be polished in the backward direction. Similarly, when the connecting plate 4 drives the special-shaped pipe to be polished according to the servo angle, it rotates and adjusts its position. In order to keep the workpiece in contact with the elastic polishing belt 9, the platform displacement adjustment mechanism can drive the horizontal movement of the moving platform 2 in the horizontal backward direction, so as to compensate the horizontal separation of the special-shaped pipe to be polished in the forward direction. displacement. To sum up, the vertical displacement and lateral displacement of the special-shaped pipe to be polished can be solved and compensated structurally during the rotation adjustment process, so as to ensure that the workpiece is always in contact with the elastic polishing belt 9 for grinding and polishing. . During the grinding process, the screw servo motor 25 controls the translation of the entire polishing belt device along the direction of the driving screw 27 through the screw and nut transmission mechanism, so as to gradually grind and polish the special-shaped pipe to be polished. That is, through the adjustment of the displacement adjustment mechanism of the system control platform, the drive of the processing servo motor 3 to the connecting plate 4, and the drive of the translation mechanism to the polishing belt device, the three-sided automatic polishing work of the special-shaped pipe fittings is realized, and the special-shaped pipe fittings are truly realized. Fully automatic grinding and polishing of pipe fittings,

异型管件三面打磨抛光完成后,需要将带轮调节气缸17的活塞杆收缩,从而将两个前侧带轮14向远离工件加工平台方向移动,同时移动平台2也在平台位移调节机构的控制下向远离抛光装置一侧回位到原点,这样一来使抛光完成的异形管件不会再与弹性抛光带9接触,且不会与弹性抛光带9的位置产生干涉,预留出足够的空间位置。然后通过加工伺服电机3转动将工件转移到远离抛光装置一侧后,抛光异型管工件两端的末端凸板末端全部遮挡第二光电开关20的光信号,从而触发电磁铁机构12断电。再继续转动运行,使抛光后的异型管工件水平以下向下倾斜状态时,抛光后的异型管工件自动滑落。本装置在移动平台2一侧设有卸料板29。抛光后的异型管工件自动滑落至卸料板29上,进而从卸料板29上滑落至地面的盛料小车31上。After the three-sided grinding and polishing of the special-shaped pipe fitting is completed, the piston rod of the pulley adjustment cylinder 17 needs to be retracted, so as to move the two front pulleys 14 away from the workpiece processing platform, and the mobile platform 2 is also under the control of the platform displacement adjustment mechanism. Return to the origin to the side away from the polishing device, so that the polished special-shaped pipe will no longer be in contact with the elastic polishing belt 9, and will not interfere with the position of the elastic polishing belt 9, and enough space is reserved. . Then, after the workpiece is transferred to the side away from the polishing device by the rotation of the machining servo motor 3, the ends of the end convex plates at both ends of the polished special-shaped pipe workpiece completely block the optical signal of the second photoelectric switch 20, thereby triggering the electromagnet mechanism 12 to power off. Continue to rotate and run, so that the polished special-shaped pipe workpiece automatically slides off when the polished special-shaped pipe workpiece is tilted downward below the level. The device is provided with a stripper plate 29 on one side of the moving platform 2 . The polished special-shaped pipe workpiece automatically slides down onto the unloading plate 29, and then slides down from the unloading plate 29 to the trolley 31 on the ground.

综上所述,通过上述方法进行异型管件的三面打磨抛光加工,不仅省时、省力、省工,而且全自动化机械控制使打磨抛光质量更好,大大降低了产品不合格率。To sum up, the three-sided grinding and polishing processing of special-shaped pipe fittings by the above method not only saves time, labor and labor, but also fully automatic mechanical control makes the grinding and polishing quality better, and greatly reduces the product failure rate.
