Description
技术领域Technical Field
本发明涉及轴承座技术领域，特别涉及一种高精度轴承座。The invention relates to the technical field of bearing seats, and in particular to a high-precision bearing seat.
背景技术Background technique
轴承座是用来安装轴承的零件，因其由顶盖和底座构成，因此称为轴承座，底座上开设有固定孔，用于将轴承座固定到机械设备上，顶盖与底座之间构成了圆形的轴瓦空间，用于固定轴承。多数情况下，为使传动轴平稳旋转，往往需要在传动轴的两端各安装有一个轴承，然后为使这两个轴承平稳固定，往往需要在机械设备上安装两个轴承座，用于将这两个轴承装固定。The bearing seat is a part used to install bearings. It is called a bearing seat because it consists of a top cover and a base. There are fixing holes on the base to fix the bearing seat to the mechanical equipment. A circular bearing space is formed between the top cover and the base to fix the bearing. In most cases, in order to make the transmission shaft rotate smoothly, it is often necessary to install a bearing at each end of the transmission shaft. Then, in order to make the two bearings stable and fixed, it is often necessary to install two bearing seats on the mechanical equipment to fix the two bearings.
轴承向轴承座内安装前，需要先将顶盖拆开，然后将轴承安装在底座内，最后再通过螺栓把顶盖固定到底座上，同时使轴承固定在顶盖与底座之间。Before installing the bearing into the bearing seat, you need to disassemble the top cover first, then install the bearing in the base, and finally fix the top cover to the base with bolts, while fixing the bearing between the top cover and the base.
然而为使轴承顺利的组装到轴承座的装配孔中，装配孔的孔腔尺寸往往会大于轴承，轴承向装配孔内组装完毕，并将轴承座锁紧后，往往会发现轴承偏斜，这将导致传动轴通过两轴承向两轴承座上组装困难，反复打开轴承座调整轴承的安装方式会影响组装效率。However, in order to smoothly assemble the bearing into the assembly hole of the bearing seat, the hole size of the assembly hole is often larger than the bearing. After the bearing is assembled into the assembly hole and the bearing seat is locked, it is often found that the bearing is skewed, which will make it difficult to assemble the drive shaft through the two bearings to the two bearing seats. Repeatedly opening the bearing seat to adjust the bearing installation method will affect the assembly efficiency.

本发明相比于现有技术的有益效果是：Compared with the prior art, the present invention has the following beneficial effects:
1、在轴承座的顶盖上开设了槽口，槽口内设置了校正轴承安装时是否发生左、右、前、后偏斜的第一精度检测辊，第一精度检测辊的前侧通过法兰盘、弹簧销以及第二精度检测辊组成的检测部件，操作人员将轴承放在轴承座的装配孔内后，接着缓慢调紧左右两组螺栓，螺栓每被调紧一次，操作人员都会向后推动一次第二精度检测辊，由第二精度检测辊向后推动一次插杆，插杆每进入一次第一插孔内，都会使插杆的后端挤压一次弹簧销，弹簧销因受到挤压就会将法兰盘向套辊上锁紧一次，第二精度检测辊还会向后挤压一次油囊，使油囊压缩排油一次，并将彩油通过油管向滴孔内注入一次，第二精度检测辊向后推动并转动时，将由第二精度检测辊带动法兰盘旋转，由法兰盘带动套辊旋转，由套辊带动第一精度检测辊旋转，如果第一精度检测辊旋转时能够摩擦着轴承外圈由外圈带着整个轴承在装配孔内旋转时，则证明第一精度检测辊的外圆面旋转一周时完全与轴承的外壁面吻合接触，即轴承的外壁面都有机会接受第一精度检测辊滚动摩擦，轴承此时在装配孔内未发生前、后、左、右偏斜，慢慢的紧固螺栓，并同时转动第一精度检测辊摩擦着轴承一直旋转，直至螺栓彻底锁紧，轴承外圈彻底被锁定在装配孔内，因轴承外圈被彻底固定，因此第一精度检测辊也不再旋转，证明轴承在轴承座内固定完毕，且固定后的轴承未发生偏斜。如果松动调节时第一精度检测辊的旋转并不能摩擦着轴承旋转，则证明轴承此时在装配孔内处于偏斜，其外圆面并没有被旋转的第一精度检测辊完全接触，需要依次调节左右连接座上的四个螺栓的松紧程度，调节轴承在装配孔内的角度，再次转动第二精度检测辊，直至调整到第一精度检测辊能够摩擦着轴承旋转为准。1. A notch is provided on the top cover of the bearing seat, and a first precision detection roller is provided in the notch to correct whether the bearing is deflected to the left, right, front or back during installation. The front side of the first precision detection roller is a detection component composed of a flange, a spring pin and a second precision detection roller. After the operator places the bearing in the assembly hole of the bearing seat, the left and right groups of bolts are slowly tightened. Each time the bolts are tightened, the operator pushes the second precision detection roller backward, and the second precision detection roller pushes the plunger backward. Each time the plunger enters the first insertion hole, the rear end of the plunger squeezes the spring pin once. The spring pin is squeezed and locks the flange to the sleeve roller once. The second precision detection roller also squeezes the oil bag backward to compress and discharge the oil once, and injects the colored oil into the drip hole through the oil pipe once. The second precision detection roller pushes backward. When rotating, the second precision detection roller will drive the flange to rotate, the flange will drive the sleeve roller to rotate, and the sleeve roller will drive the first precision detection roller to rotate. If the first precision detection roller can rub the outer ring of the bearing when it rotates, and the outer ring drives the entire bearing to rotate in the assembly hole, it proves that the outer cylindrical surface of the first precision detection roller is completely in contact with the outer wall surface of the bearing when it rotates one circle, that is, the outer wall surface of the bearing has the opportunity to receive the rolling friction of the first precision detection roller, and the bearing does not deflect forward, backward, left or right in the assembly hole at this time. Slowly tighten the bolts, and at the same time rotate the first precision detection roller to rub the bearing and rotate until the bolts are completely tightened and the outer ring of the bearing is completely locked in the assembly hole. Because the outer ring of the bearing is completely fixed, the first precision detection roller no longer rotates, which proves that the bearing is fixed in the bearing seat and the fixed bearing is not deflected. If the rotation of the first precision detection roller cannot rub the bearing when it is loosened, it proves that the bearing is tilted in the assembly hole at this time, and its outer cylindrical surface is not completely contacted by the rotating first precision detection roller. It is necessary to adjust the tightness of the four bolts on the left and right connecting seats in turn, adjust the angle of the bearing in the assembly hole, and rotate the second precision detection roller again until the first precision detection roller can rotate by rubbing the bearing.
2、为了提高判别效果，如果轴承能够顺利的完成整周旋转时，则滴落在轴承上的彩油就会在轴承外壁上留下整圈轨迹，反之，如果轴承未能完成整周旋转时，则滴落在轴承上的彩油不能留下整圈轨迹，通过这两种直观的检测手段，来校正轴承在装配孔内是否发生前、后、左、右偏斜；由此可知，轴承在向装配孔内固定时因其外圈被第一精度检测辊摩擦着同步校正，因此轴承最终固定到装配孔内时，确保轴承不会发生偏斜，最终因顶盖和底座的重合面彻底重合并锁紧，装配孔彻底变为圆形，轴承内圈与装配孔的孔心也就能确保在同一轴线上，即轴承向轴承座内固定后的精度得到了提高。2. In order to improve the identification effect, if the bearing can smoothly complete a full rotation, the colored oil dripping on the bearing will leave a full circle track on the outer wall of the bearing. Conversely, if the bearing fails to complete a full rotation, the colored oil dripping on the bearing cannot leave a full circle track. These two intuitive detection methods are used to correct whether the bearing is skewed forward, backward, left or right in the assembly hole. It can be seen that when the bearing is fixed in the assembly hole, its outer ring is rubbed by the first precision detection roller for synchronous correction. Therefore, when the bearing is finally fixed in the assembly hole, it is ensured that the bearing will not be skewed. Finally, because the overlapping surfaces of the top cover and the base are completely overlapped and locked, the assembly hole is completely turned into a circle, and the inner ring of the bearing and the center of the assembly hole can also be ensured to be on the same axis, that is, the accuracy of the bearing after being fixed in the bearing seat is improved.
3、轴承向轴承座内安装时提高了安装精度，以同样的方法把另一侧轴承组装到另一侧的轴承座上，接下来再把传动轴安装在两轴承的内圈上，最后再将左右连接座上的螺栓以对角锁紧的方式逐个锁紧，轴承外圈不再旋转。进行完上述检测后，将第二精度检测辊向前拉动，使插杆脱离法兰盘，并同时使插杆脱离弹簧销，此时弹簧销不再将法兰盘锁紧在套辊上，第二精度检测辊因朝前复位运动，而将油囊由压缩变为拉伸变长，并利用油嘴向油囊内补充彩油，与此同时因弹簧销不再将法兰盘锁定在套辊上，因此第二精度检测辊在套辊上将会获得自由，第二精度检测辊完全可以在套辊上单独旋转，此时让组装后的传动轴单独旋转，观看传动轴旋转一周时，其外圆面是否能够与第二精度检测辊的外圆面全面接触，如果传动轴旋转一周并不能完全带动第二精度检测辊旋转，则证明传动轴在两轴承之间发生偏斜，此时向前归位后的第二精度检测辊，又具有检测传动轴是否偏心的这一检测功能，装配时传动轴的安装精度也能够被检测。3. The installation accuracy is improved when the bearing is installed into the bearing seat. The bearing on the other side is assembled to the bearing seat on the other side in the same way. Next, the transmission shaft is installed on the inner rings of the two bearings. Finally, the bolts on the left and right connecting seats are tightened one by one in a diagonal locking manner, and the outer ring of the bearing no longer rotates. After completing the above inspection, pull the second precision inspection roller forward to disengage the insertion rod from the flange and the spring pin at the same time. At this time, the spring pin no longer locks the flange on the sleeve roller, and the second precision inspection roller resets forward, which changes the oil bag from compression to tension and lengthens, and uses the oil nozzle to replenish colored oil into the oil bag. At the same time, because the spring pin no longer locks the flange on the sleeve roller, the second precision inspection roller will be free on the sleeve roller, and the second precision inspection roller can rotate independently on the sleeve roller. At this time, let the assembled transmission shaft rotate independently to observe whether its outer cylindrical surface can fully contact the outer cylindrical surface of the second precision inspection roller when the transmission shaft rotates one circle. If the transmission shaft cannot completely drive the second precision inspection roller to rotate after one circle, it proves that the transmission shaft is deflected between the two bearings. At this time, the second precision inspection roller, which has returned to its position forward, has the detection function of detecting whether the transmission shaft is eccentric, and the installation accuracy of the transmission shaft can also be detected during assembly.
第二精度检测辊不仅是为使法兰盘带动套辊，并由第套辊带动第一精度检测辊旋转时，操作更加省力，而且第二精度检测辊向前运动时，还能够压缩油囊向轴承外圈提供彩油，具有直观的检测效果；并且第二精度检测辊对轴承检测完毕，退位后还能够对传动轴是否偏心进行校正。The second precision detection roller is not only used to make the flange drive the sleeve roller, and the sleeve roller drives the first precision detection roller to rotate, which makes the operation more labor-saving, but also when the second precision detection roller moves forward, it can compress the oil bag to provide colored oil to the outer ring of the bearing, which has an intuitive detection effect; and after the second precision detection roller completes the bearing inspection, it can also correct whether the drive shaft is eccentric after retreating.

具体实施方式Detailed ways
以下结合附图，对本发明上述的和另外的实施方式和优点进行清楚、完整地描述。显然，所描述的实施方式仅仅是本发明的部分实施方式，而不是全部实施方式。The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.
在一种实施方式中，如图1-图6所示：In one embodiment, as shown in Figures 1 to 6:
本实施方式提供的一种高精度轴承座，包括底座1，底座1的顶部可拆卸的安装有顶盖2，底座1和顶盖2的左右两端各设有前后两组连接座3，底座1和顶盖2之间构成用于组装轴承的装配孔27，这是现有轴承座的一般结构，轴承向装配孔27内组装前，松开左右连接座3上的螺栓，将顶盖2从底座1上拆除，或者松动左右连接座3上的螺栓，将顶盖2向上分离，使装配孔27调整到大于轴承后，再将轴承放在装配孔27中，最后再将左右连接座3上的螺栓分别锁紧，使轴承固定。除此之外，本发明在顶盖2上开设了一个槽口4，槽口4的内端与顶盖2内壁上下相通；顶盖2上设置了精度自测机构5，精度自测机构5包括安装在槽口4内的第一精度检测辊8，第一精度检测辊8的轴线与装配孔27平行，第一精度检测辊8的滚动面与顶盖2的内腔面重合；轴承向装配孔27中组装后(左右连接座3上的螺栓未锁紧)，转动第一精度检测辊8，此时由于轴承还未被完全锁紧在装配孔27内，因此第一精度检测辊8旋转时，会利用其滚面摩擦着轴承在装配孔27内旋转。A high-precision bearing seat provided in this embodiment includes a base 1, a top cover 2 is detachably installed on the top of the base 1, and two groups of front and rear connecting seats 3 are respectively provided at the left and right ends of the base 1 and the top cover 2. An assembly hole 27 for assembling the bearing is formed between the base 1 and the top cover 2. This is a general structure of an existing bearing seat. Before the bearing is assembled into the assembly hole 27, the bolts on the left and right connecting seats 3 are loosened and the top cover 2 is removed from the base 1, or the bolts on the left and right connecting seats 3 are loosened and the top cover 2 is separated upward. After the assembly hole 27 is adjusted to be larger than the bearing, the bearing is placed in the assembly hole 27, and finally the bolts on the left and right connecting seats 3 are tightened respectively to fix the bearing. In addition, the present invention opens a slot 4 on the top cover 2, and the inner end of the slot 4 is connected to the inner wall of the top cover 2 up and down; a precision self-testing mechanism 5 is arranged on the top cover 2, and the precision self-testing mechanism 5 includes a first precision detection roller 8 installed in the slot 4, and the axis of the first precision detection roller 8 is parallel to the assembly hole 27, and the rolling surface of the first precision detection roller 8 coincides with the inner cavity surface of the top cover 2; after the bearing is assembled into the assembly hole 27 (the bolts on the left and right connecting seats 3 are not tightened), the first precision detection roller 8 is rotated. At this time, since the bearing has not been completely locked in the assembly hole 27, when the first precision detection roller 8 rotates, it will use its rolling surface to rub the bearing and rotate in the assembly hole 27.
第一精度检测辊8的前端贯穿至顶盖2前侧之外，并且在第一精度检测辊8的前端固定有套辊9，实质上是第一精度检测辊8的前端的转轴伸出顶盖2前侧，然后在其前端转轴上套设并固定有套辊9，第一精度检测辊8旋转时，还会带着套辊9旋转，也即套辊9旋转时会带着第一精度检测辊8旋转，精度自测机构5还包括套设在套辊9上的法兰盘10，法兰盘10上设有滑动配合在套辊9上的滑套25，滑套25的垂直方向上安装有弹簧销11，弹簧销11的内端贯穿至滑套25内；弹簧销11为现有技术，其具体结构不再赘述，弹簧销11的外端一旦受到触碰，就会产生挤压效果，导致弹簧销11的内端压在套辊9上，此时法兰盘10相当于通过弹簧销11与套辊9连接，套辊9旋转时就会带着法兰盘10旋转，也即法兰盘10此时旋转时，就会带着套辊9旋转，由套辊9带着第一精度检测辊8旋转，而弹簧销11的外端触碰因素消失时，弹簧销11的内端就会向外弹射并与套辊9分离，此时法兰盘10仅套在套辊9上，套辊9此时旋转时并不会带着法兰盘10旋转，也即此时法兰盘10旋转时，并不会带着套辊9旋转。The front end of the first precision detection roller 8 passes through the front side of the top cover 2, and a sleeve roller 9 is fixed to the front end of the first precision detection roller 8. In essence, the rotating shaft of the front end of the first precision detection roller 8 extends out of the front side of the top cover 2, and then the sleeve roller 9 is sleeved and fixed on its front end rotating shaft. When the first precision detection roller 8 rotates, it will also rotate with the sleeve roller 9, that is, when the sleeve roller 9 rotates, it will rotate with the first precision detection roller 8. The precision self-testing mechanism 5 also includes a flange 10 sleeved on the sleeve roller 9, and the flange 10 is provided with a sliding sleeve 25 that is slidably matched with the sleeve roller 9. A spring pin 11 is installed in the vertical direction of the sliding sleeve 25, and the inner end of the spring pin 11 passes through the sliding sleeve 25; the spring pin 11 is a prior art, and its specific The structure will not be elaborated any more. Once the outer end of the spring pin 11 is touched, an extrusion effect will be generated, causing the inner end of the spring pin 11 to be pressed on the sleeve roller 9. At this time, the flange 10 is equivalent to being connected to the sleeve roller 9 through the spring pin 11. When the sleeve roller 9 rotates, it will rotate with the flange 10, that is, when the flange 10 rotates at this time, it will rotate with the sleeve roller 9, and the sleeve roller 9 will rotate with the first precision detection roller 8. When the touch factor of the outer end of the spring pin 11 disappears, the inner end of the spring pin 11 will be ejected outward and separated from the sleeve roller 9. At this time, the flange 10 is only sleeved on the sleeve roller 9, and the sleeve roller 9 does not rotate with the flange 10 when it rotates at this time, that is, when the flange 10 rotates at this time, it does not rotate with the sleeve roller 9.
接上述，精度自测机构5还包括套设在套辊9上的第二精度检测辊12，第二精度检测辊12位于法兰盘10的前侧和顶盖2的前侧，第二精度检测辊12的后端固定有朝后水平伸展的插杆13，法兰盘10上开设有与插杆13和弹簧销11在同一直线上的第一插孔14；向后推动第二精度检测辊12，将插杆13穿过第一插孔14顶到弹簧销11上，此时在插杆13连接下，使第二精度检测辊12与法兰盘10连接，与此同时插杆13的后端压到弹簧销11上，使弹簧销11的内端顶到套辊9上，用以将法兰盘10锁紧在套辊9上，同时使第二精度检测辊12通过插杆13连接在法兰盘10上；此时转动第二精度检测辊12，由第二精度检测辊12通过插杆13带动法兰盘10旋转，由法兰盘10带动套辊9旋转，由套辊9带动第一精度检测辊8旋转；第二精度检测辊12此时的作用：一是推动插杆13，触发弹簧销11将法兰盘10固定在套辊9上，二是带着插杆13旋转时，由插杆13带动法兰盘10，并由法兰盘10带动套辊9旋转，再由套辊9带动第一精度检测辊8旋转，利用第一精度检测辊8旋转时的滚面是否能够带动轴承旋转，来检测轴承安装到装配孔27内时，其轴心是否与装配孔27的轴心在同一直线上，该检测功能用来提高轴承向装配孔27内安装后的精度。In continuation of the above, the precision self-testing mechanism 5 also includes a second precision detection roller 12 sleeved on the sleeve roller 9, the second precision detection roller 12 is located on the front side of the flange 10 and the front side of the top cover 2, and a plug rod 13 extending horizontally backward is fixed to the rear end of the second precision detection roller 12, and a first insertion hole 14 which is in the same straight line with the plug rod 13 and the spring pin 11 is opened on the flange 10; the second precision detection roller 12 is pushed backward, and the plug rod 13 is passed through the first insertion hole 14 and pushed onto the spring pin 11. At this time, under the connection of the plug rod 13, the second precision detection roller 12 is connected to the flange 10, and at the same time, the rear end of the plug rod 13 is pressed onto the spring pin 11, so that the inner end of the spring pin 11 is pushed onto the sleeve roller 9, so as to lock the flange 10 on the sleeve roller 9, and at the same time, the second precision detection roller 12 is connected to the flange 10 through the plug rod 13. At this time, the second precision detection roller 12 is rotated, and the second precision detection roller 12 drives the flange 10 to rotate through the insertion rod 13, and the flange 10 drives the sleeve roller 9 to rotate, and the sleeve roller 9 drives the first precision detection roller 8 to rotate; the role of the second precision detection roller 12 at this time is: first, it pushes the insertion rod 13 to trigger the spring pin 11 to fix the flange 10 on the sleeve roller 9; second, when it rotates with the insertion rod 13, the insertion rod 13 drives the flange 10, and the flange 10 drives the sleeve roller 9 to rotate, and then the sleeve roller 9 drives the first precision detection roller 8 to rotate, and the rolling surface of the first precision detection roller 8 when rotating can drive the bearing to rotate, so as to detect whether the axis of the bearing is in the same straight line with the axis of the assembly hole 27 when it is installed in the assembly hole 27. This detection function is used to improve the accuracy of the bearing after being installed in the assembly hole 27.
精度自测机构5还包括套设在套辊9上的油囊7，油囊7的一端连接在法兰盘10上，另一端连接在第二精度检测辊12上，顶盖2上开设有滴孔6，滴孔6与油囊7之间连接有油管24，油囊7内装有彩油，滴孔6的内端贯通顶盖2的内壁，第二精度检测辊12朝后运动时挤压油囊7，使油囊7内的彩油通过油管24进入滴孔6内，由滴孔6的内端滴到轴承上。The precision self-testing mechanism 5 also includes an oil bag 7 sleeved on the sleeve roller 9, one end of the oil bag 7 is connected to the flange 10, and the other end is connected to the second precision detection roller 12. A drip hole 6 is opened on the top cover 2, and an oil pipe 24 is connected between the drip hole 6 and the oil bag 7. The oil bag 7 is filled with colored oil. The inner end of the drip hole 6 passes through the inner wall of the top cover 2. When the second precision detection roller 12 moves backward, the oil bag 7 is squeezed, so that the colored oil in the oil bag 7 enters the drip hole 6 through the oil pipe 24 and drips onto the bearing from the inner end of the drip hole 6.
具体工作原理：操作人员将左右连接座3上的螺栓松开，将顶盖2向上脱离底座1，使装配孔27的尺寸变大(此时装配孔27为椭圆)，将轴承从轴承座的前侧或后侧装入装配孔27内，并将顶盖2重新闭合到底座1上，接着将左右连接座3上的螺栓依次调节锁紧，每调紧一次螺栓，都向后推动一次第二精度检测辊12，由第二精度检测辊12向后推动一次插杆13，插杆13每进入一次第一插孔14内，都会使插杆13的后端挤压一次弹簧销11，弹簧销11因受到挤压就会将法兰盘10向套辊9上锁紧一次，第二精度检测辊12还会向后挤压一次油囊7，使油囊7压缩排油一次，并将彩油通过油管24向滴孔6内注入一次，第二精度检测辊12向后推动并转动时，将由第二精度检测辊12带动法兰盘10旋转，由法兰盘10带动套辊9旋转，由套辊9带动第一精度检测辊8旋转，如果第一精度检测辊8旋转时能够摩擦着轴承外圈由外圈带着整个轴承在装配孔27内旋转时，则证明第一精度检测辊8的外圆面旋转一周时完全与轴承的外壁面吻合接触，即轴承的外壁面(外圈壁面)都有机会接受第一精度检测辊8滚动摩擦，轴承此时在装配孔27内未发生前、后、左、右偏斜，慢慢的紧固左右连接座3上的四个螺栓，并同时转动第一精度检测辊8摩擦着轴承一直旋转，直至四个螺栓彻底锁紧，轴承外圈彻底被锁定在装配孔27内，因轴承外圈被彻底固定，因此第一精度检测辊8也不再旋转，证明轴承在轴承座内固定完毕，且固定后的轴承未发生偏斜。如果轴承不能随第一精度检测辊8同步旋转一周，则证明轴承此时在装配孔27内处于偏斜，其外圆面并没有被旋转的第一精度检测辊8完全接触，需要依次调节左右连接座3上的四个螺栓的松紧程度，调节轴承在装配孔27内的角度，再次转动第二精度检测辊12，由第二精度检测辊12带动法兰盘10再次旋转，由法兰盘10带动套辊9再次旋转，由套辊9带动第一精度检测辊8再次旋转，观看轴承是否被第一精度检测辊8摩擦着完成整周旋转，为了提高判别效果，如果轴承能够顺利的完成整周旋转时，则滴落在轴承上的彩油就会在轴承外壁上留下整圈轨迹，反之，如果轴承未能完成整周旋转时，则滴落在轴承上的彩油不能留下整圈轨迹，通过这两种直观的检测手段，来校正轴承在装配孔27内是否发生前、后、左、右偏斜；如果轴承在装配孔27内的合理位置上(即轴承在装配孔27内的前、后、左、右位置未发生偏斜)，则第一精度检测辊8旋转就能够摩擦着轴承外圈带着轴承在装配孔27内做整周旋转，并且滴落的彩油就会在轴承外圈上留下一圈轨迹，与此同时操作人员以对的方式，使顶盖2与底座1逐渐锁紧固定，并且在此期间一直使第一精度检测辊8摩擦着轴承外圈使轴承在装配孔27内旋转，并且随着这四根螺栓将顶盖2彻底紧固在底座1上，轴承外圈就会被顶盖2和底座1彻底固定，也即轴承彻底被固定在装配孔27内，由此可知，轴承在向装配孔27内固定时因其外圈被第一精度检测辊8摩擦着同步校正，因此轴承最终固定到装配孔27内时，确保轴承不会发生偏斜，最终因顶盖2和底座1的重合面彻底重合并锁紧，装配孔27彻底变为圆形，轴承内圈与装配孔27的孔心也就能确保在同一轴线上，即轴承向轴承座内固定后的精度得到了提高。Specific working principle: the operator loosens the bolts on the left and right connecting seats 3, separates the top cover 2 upward from the base 1, enlarges the size of the assembly hole 27 (the assembly hole 27 is an ellipse at this time), installs the bearing into the assembly hole 27 from the front or rear side of the bearing seat, and closes the top cover 2 to the base 1 again, then adjusts and locks the bolts on the left and right connecting seats 3 in turn, and each time the bolts are tightened, the second precision detection roller 12 is pushed backward once, and the second precision detection roller 12 pushes the plunger 13 backward once, and each time the plunger 13 enters the first insertion hole 14, the rear end of the plunger 13 will squeeze the spring pin 11 once, and the spring pin 11 will lock the flange 10 to the sleeve roller 9 once due to the squeezing, and the second precision detection roller 12 will also squeeze the oil bag 7 backward once, so that the oil bag 7 is compressed and the oil is discharged once, and the colored oil is injected into the drip hole 6 once through the oil pipe 24, and when the second precision detection roller 12 is pushed backward and rotated, the second The precision detection roller 12 drives the flange 10 to rotate, and the flange 10 drives the sleeve roller 9 to rotate, and the sleeve roller 9 drives the first precision detection roller 8 to rotate. If the first precision detection roller 8 can rub the outer ring of the bearing when it rotates, and the outer ring drives the entire bearing to rotate in the assembly hole 27, it proves that the outer cylindrical surface of the first precision detection roller 8 is completely in contact with the outer wall surface of the bearing when it rotates one circle, that is, the outer wall surface of the bearing (outer ring wall surface) has the opportunity to receive the rolling friction of the first precision detection roller 8, and the bearing does not deflect forward, backward, left or right in the assembly hole 27 at this time. Slowly tighten the four bolts on the left and right connecting seats 3, and at the same time turn the first precision detection roller 8 to rub the bearing and rotate until the four bolts are completely tightened, and the outer ring of the bearing is completely locked in the assembly hole 27. Because the outer ring of the bearing is completely fixed, the first precision detection roller 8 no longer rotates, which proves that the bearing is fixed in the bearing seat and the fixed bearing is not deflected. If the bearing cannot rotate synchronously with the first precision detection roller 8 for one circle, it proves that the bearing is skewed in the assembly hole 27 at this time, and its outer cylindrical surface is not fully contacted by the rotating first precision detection roller 8. It is necessary to adjust the tightness of the four bolts on the left and right connecting seats 3 in turn, adjust the angle of the bearing in the assembly hole 27, and rotate the second precision detection roller 12 again. The second precision detection roller 12 drives the flange 10 to rotate again, and the flange 10 drives the sleeve roller 9 to rotate again. The sleeve roller 9 drives the first precision detection roller 8 to rotate again to see whether the bearing is rubbed by the first precision detection roller 8 to complete a full rotation. In order to improve the discrimination effect, if the bearing can successfully complete a full rotation, the colored oil dripping on the bearing will leave a full circle track on the outer wall of the bearing. On the contrary, if the bearing fails to complete a full rotation, the colored oil dripping on the bearing cannot leave a full circle track. Through these two intuitive detection methods, it is possible to correct whether the bearing is skewed forward, backward, left or right in the assembly hole 27; if the bearing is in a reasonable position in the assembly hole 27 (that is, the bearing is in the assembly hole 27, the first precision detection roller 8 can rotate to rub the outer ring of the bearing and make the bearing rotate in the assembly hole 27 for a full circle, and the dripping colored oil will leave a circle of tracks on the outer ring of the bearing. At the same time, the operator gradually locks and fixes the top cover 2 and the base 1 in a right manner, and during this period, the first precision detection roller 8 is kept rubbing the outer ring of the bearing to make the bearing rotate in the assembly hole 27. As the four bolts completely fasten the top cover 2 to the base 1, the outer ring of the bearing will The top cover 2 and the base 1 are completely fixed, that is, the bearing is completely fixed in the assembly hole 27. It can be seen that when the bearing is fixed in the assembly hole 27, its outer ring is rubbed and synchronously corrected by the first precision detection roller 8. Therefore, when the bearing is finally fixed in the assembly hole 27, it is ensured that the bearing will not be deflected. Finally, because the overlapping surfaces of the top cover 2 and the base 1 are completely overlapped and locked, the assembly hole 27 is completely turned into a circle, and the center of the inner ring of the bearing and the assembly hole 27 can also be ensured to be on the same axis, that is, the accuracy of the bearing after being fixed in the bearing seat is improved.
轴承向轴承座内安装时提高了安装精度，以同样的方法把另一侧轴承组装到另一侧的轴承座(在机械行业中，同一根传动轴会在两端各设置一个轴承，并且为使这两个轴承固定到机构上，会在两个轴承上都安装一个轴承座)上，接下来再把传动轴安装在两轴承的内圈上，最后再将左右连接座3上的螺栓以对角锁紧的方式逐个锁紧，轴承外圈不再旋转。进行完上述检测后，将第二精度检测辊12向前拉动，使插杆13脱离法兰盘10，并同时使插杆13脱离弹簧销11，此时弹簧销11不再将法兰盘10锁紧在套辊9上，第二精度检测辊12因朝前复位运动，而将油囊7由压缩变为拉伸变长，并利用油嘴26向油囊7内补充彩油，与此同时因弹簧销11不再将法兰盘10锁定在套辊9上，因此第二精度检测辊12在套辊9上将会获得自由，第二精度检测辊12完全可以在套辊9上单独旋转，此时传动轴单独旋转一周，观看其外圆面是否能够与第二精度检测辊12的外圆面全面接触，并是否能够带动第二精度检测辊12单独旋转，如果此时第二精度检测辊12能够在传动轴的旋转摩擦下同步旋转，则校正出传动轴安装在两轴承之间未发生偏斜。The installation accuracy is improved when the bearing is installed into the bearing seat. The bearing on the other side is assembled to the bearing seat on the other side in the same way (in the machinery industry, a bearing is set at each end of the same transmission shaft, and a bearing seat is installed on both bearings to fix the two bearings to the mechanism). Next, the transmission shaft is installed on the inner rings of the two bearings. Finally, the bolts on the left and right connecting seats 3 are tightened one by one in a diagonal locking manner, and the outer ring of the bearing no longer rotates. After completing the above-mentioned inspection, the second precision inspection roller 12 is pulled forward to disengage the insertion rod 13 from the flange 10, and at the same time, the insertion rod 13 is disengaged from the spring pin 11. At this time, the spring pin 11 no longer locks the flange 10 on the sleeve roller 9, and the second precision inspection roller 12 resets forward, and the oil bag 7 changes from compression to tension and becomes longer, and the oil nozzle 26 is used to replenish the colored oil into the oil bag 7. At the same time, because the spring pin 11 no longer locks the flange 10 on the sleeve roller 9, the second precision inspection roller 12 will be free on the sleeve roller 9, and the second precision inspection roller 12 can be completely rotated alone on the sleeve roller 9. At this time, the transmission shaft rotates alone for one circle to see whether its outer cylindrical surface can fully contact the outer cylindrical surface of the second precision inspection roller 12, and whether it can drive the second precision inspection roller 12 to rotate alone. If the second precision inspection roller 12 can rotate synchronously under the rotational friction of the transmission shaft at this time, it is corrected that the transmission shaft is installed between the two bearings without deflection.
本实施方式中，第二精度检测辊12不仅是为使法兰盘10带动套辊9，并由第套辊9带动第一精度检测辊8旋转时，操作更加省力，而且第二精度检测辊12向前运动时，还能够压缩油囊7向轴承外圈提供彩油，并且在第一精度检测辊8旋转时，用以检测轴承是否能够被第一精度检测辊8带动完成整周旋转，对轴承在轴承座内安装后完成精度检测。将彩油、旋转以及精度检测实现同步，便于操作。In this embodiment, the second precision detection roller 12 is not only used to make the flange 10 drive the sleeve roller 9, and the sleeve roller 9 drives the first precision detection roller 8 to rotate, which is more labor-saving, but also can compress the oil bag 7 to provide color oil to the outer ring of the bearing when the second precision detection roller 12 moves forward, and when the first precision detection roller 8 rotates, it is used to detect whether the bearing can be driven by the first precision detection roller 8 to complete a full rotation, and complete the accuracy detection of the bearing after it is installed in the bearing seat. The color oil, rotation and accuracy detection are synchronized for easy operation.
顶盖2的内壁面为弧形，沿着顶盖2的弧形内壁的中部开设有一条油道15，滴孔6的内端贯通油道15，油道15的两端沿着顶盖2的弧形内壁分别到达槽口4的两侧。来自于油囊7的彩油通过滴孔6落入油道15内，经油道15限制后，确保轴承外圈旋转时能够留下一道规整的油迹。如果轴承外圈上留下的油迹规整且为整圈，则证明轴承在装配孔27内安装时精度合格。The inner wall of the top cover 2 is arc-shaped, and an oil passage 15 is opened along the middle of the arc-shaped inner wall of the top cover 2. The inner end of the drip hole 6 passes through the oil passage 15, and the two ends of the oil passage 15 reach the two sides of the slot 4 along the arc-shaped inner wall of the top cover 2. The colored oil from the oil bag 7 falls into the oil passage 15 through the drip hole 6. After being restricted by the oil passage 15, it is ensured that a regular oil mark can be left when the outer ring of the bearing rotates. If the oil mark left on the outer ring of the bearing is regular and complete, it proves that the bearing is installed in the assembly hole 27 with qualified accuracy.
沿着第一精度检测辊8的圆周面方向开设深槽16，深槽16位于油道15的出油路径上，深槽16的槽底高于油道15。第一精度检测辊8利用滚动面(外圆面)摩擦着轴承外圈，并带整个轴承旋转时，实则是利用深槽16两侧区域为有效滚动面摩擦着轴承外圈，并带着整个轴承旋转，滴落到轴承外圈面上的彩油轨迹能够避开第一精度检测辊8的深槽16部分，防止第一精度检测辊8将轨迹抹平，或摩擦干净，影响观测效果。A deep groove 16 is provided along the circumferential surface of the first precision detection roller 8. The deep groove 16 is located on the oil outlet path of the oil channel 15, and the bottom of the deep groove 16 is higher than the oil channel 15. When the first precision detection roller 8 uses the rolling surface (outer cylindrical surface) to rub the outer ring of the bearing and rotates the entire bearing, it actually uses the two sides of the deep groove 16 as an effective rolling surface to rub the outer ring of the bearing and rotates the entire bearing. The track of the colored oil dripping onto the outer ring surface of the bearing can avoid the deep groove 16 part of the first precision detection roller 8, preventing the first precision detection roller 8 from smoothing the track or rubbing it clean, which affects the observation effect.
槽口4上安装有扣盖17，扣盖17是透明罩，扣盖17用于遮盖灰尘，避免灰尘穿过槽口4进入油道15内，扣盖17的一端铰接在槽口4的一侧上。A buckle cover 17 is installed on the slot 4 . The buckle cover 17 is a transparent cover and is used to cover dust to prevent dust from passing through the slot 4 and entering the oil passage 15 . One end of the buckle cover 17 is hinged on one side of the slot 4 .
槽口4的前后两端各镶嵌有一个在同一直线上的转套18，第一精度检测辊8的后端装配在后侧的转套18上，第一精度检测辊8的前端穿过并装配在前侧的转套18上，在第一精度检测辊8的前后两端形成转动部件，提高转动效果。The front and rear ends of the slot 4 are each inlaid with a rotating sleeve 18 on the same straight line. The rear end of the first precision detection roller 8 is assembled on the rotating sleeve 18 on the rear side, and the front end of the first precision detection roller 8 passes through and is assembled on the rotating sleeve 18 on the front side. Rotating parts are formed at the front and rear ends of the first precision detection roller 8 to improve the rotation effect.
第二精度检测辊12上开设有若干个减重孔19。A plurality of weight-reducing holes 19 are formed on the second precision detection roller 12 .
在另一种实施方式中，法兰盘10面向第二精度检测辊12的前端面上环形阵列的安装有三根相互平行的螺杆21，螺杆21还与轴承座的轴线平行，第二精度检测辊12上环形阵列的开设有三个第二插孔22，三根螺杆21分别插入三个第二插孔22内，每一根螺杆21的前端安装有一个限位螺母23；插杆13的长度小于螺杆21的长度，螺杆21仅在前端开设有用于安装限位螺母23的外螺纹，螺杆21的后段为光轴。三根螺杆21通过第二插孔22插在第二精度检测辊12上，使得第二精度检测辊12除了中间位置滑动在套辊9上形成前后滑动时的定位导向以外，其前后滑行时还利用这三根螺杆21作为前后滑动时的定位导向，同时也保证了第二精度检测辊12平行在轴承座的前侧。In another embodiment, three parallel screws 21 are installed in a circular array on the front end surface of the flange 10 facing the second precision detection roller 12. The screws 21 are also parallel to the axis of the bearing seat. Three second insertion holes 22 are opened in a circular array on the second precision detection roller 12. The three screws 21 are respectively inserted into the three second insertion holes 22. A limit nut 23 is installed at the front end of each screw 21. The length of the insertion rod 13 is less than the length of the screw 21. The screw 21 is only provided with an external thread for installing the limit nut 23 at the front end, and the rear section of the screw 21 is an optical axis. The three screws 21 are inserted into the second precision detection roller 12 through the second insertion holes 22, so that the second precision detection roller 12 not only slides on the sleeve roller 9 in the middle position to form a positioning guide when sliding forward and backward, but also uses these three screws 21 as a positioning guide when sliding forward and backward, and also ensures that the second precision detection roller 12 is parallel to the front side of the bearing seat.
需要进一步说明的是，油嘴26也是指油壶，壶底通过管道连接在油囊7上，管道上带有单向阀，油囊7每压缩一次都会排油一次，油囊7每拉伸复位一次就会将单向阀开启一次，油嘴26就会向油囊7补一次彩油。油囊7采用橡胶波纹管，内部填充的钢丝可以理解为沿着波纹走向分布的弹簧，提高了油囊7强度的同时，在第二精度检测辊12朝前复位时，也能够便于油囊7快速复原拉长。It should be further explained that the oil nozzle 26 also refers to an oil pot, the bottom of which is connected to the oil bladder 7 through a pipeline, and the pipeline is provided with a one-way valve. The oil bladder 7 will discharge oil once each time it is compressed, and the one-way valve will be opened once each time the oil bladder 7 is stretched and reset, and the oil nozzle 26 will replenish the oil to the oil bladder 7. The oil bladder 7 adopts a rubber bellows, and the steel wire filled inside can be understood as a spring distributed along the direction of the corrugation, which improves the strength of the oil bladder 7 and facilitates the rapid recovery and elongation of the oil bladder 7 when the second precision detection roller 12 resets forward.
需要进一步说明的是，弹簧销11的顶端(内部顶杆的顶端)朝向于插杆13方向倾斜的斜面，插杆13顶到斜面上时，就会推动弹簧销11的顶杆顶到套辊9上，除此之外并没有对弹簧销11的其它结构进行改时，也不影响弹簧销11的现有锁紧原理。It needs to be further explained that the top end of the spring pin 11 (the top end of the internal push rod) faces the inclined surface inclined in the direction of the insertion rod 13. When the insertion rod 13 hits the inclined surface, it will push the push rod of the spring pin 11 onto the sleeve roller 9. Apart from this, no other structure of the spring pin 11 is changed, and the existing locking principle of the spring pin 11 is not affected.
