具体实施方式 Detailed ways
如图1－2所示，本发明一个实施例，直线导轨2设置在底座1的上面。压装平台3设置在直线导轨2上，并可在直线导轨上移动。压装平台3上设置有两两对称四个定位块4以及定位块之间的支撑平台。定位块4实现对所要压装的车轮的定位。作为支撑平台5上下移动的导向结构，定位块4的内侧还设置有垂直于支撑平台５的凹形卡槽7，并且支撑平台5设置有与定位块4内侧凹形卡槽7滑动配合的凸起，使得支撑平台5可沿凹形卡槽7方向上下移动。支撑平台5上还有四个设置于同一水平面上的滚轮8。本实施例中支撑平台升降装置包括中空液压缸9和气动液压泵10，中空液压缸9与气动液压泵10相连接。支撑平台５还设置容纳中空液压缸９的液压缸定位套６。 As shown in FIGS. 1-2 , in one embodiment of the present invention, the linear guide rail 2 is arranged on the base 1 . The press mounting platform 3 is arranged on the linear guide rail 2 and can move on the linear guide rail. The press-fitting platform 3 is provided with four symmetrical positioning blocks 4 in pairs and a supporting platform between the positioning blocks. The positioning block 4 realizes the positioning of the wheel to be press-fitted. As a guide structure for the support platform 5 to move up and down, the inner side of the positioning block 4 is also provided with a concave slot 7 perpendicular to the support platform 5, and the support platform 5 is provided with a protrusion that is slidably matched with the concave slot 7 inside the positioning block 4. so that the support platform 5 can move up and down along the direction of the concave slot 7. Also have four rollers 8 that are arranged on the same level on the support platform 5 . The supporting platform lifting device in this embodiment includes a hollow hydraulic cylinder 9 and a pneumatic hydraulic pump 10 , and the hollow hydraulic cylinder 9 is connected with the pneumatic hydraulic pump 10 . The support platform 5 is also provided with a hydraulic cylinder positioning sleeve 6 for accommodating the hollow hydraulic cylinder 9 .
此外，底座2还设置有高度调节装置调整块11和调整螺杆12，如图1所示。通过调节调整块11和调整螺杆12，可以使底座上压装平台３保持水平状态，从而保证车轮连接销压装装置底座上压装平台的水平度要求。 In addition, the base 2 is also provided with a height adjustment device, an adjustment block 11 and an adjustment screw 12, as shown in FIG. 1 . By adjusting the adjustment block 11 and the adjustment screw 12, the press-fitting platform 3 on the base can be kept in a horizontal state, thereby ensuring the levelness requirement of the press-fitting platform on the base of the wheel connecting pin press-fitting device.
在车轮连接销压装过程中，首先将车轮放置在压装平台3上，通过定位块4对其定位。然后将压装平台3沿直线导轨2移动至压力机正下方，通过压力机将连接销压入安装孔。当完成一个连接销的压装后，通过气动液压泵10使得中空液压缸9将支撑平台5往上顶。支撑平台5会沿着导向结构凹形卡槽7方向向上移动，当移至合适位置时，车轮脱离定位块4。此时，车轮通过滚轮8的滚动，使得车轮转动，调整至下一个需要压装连接销的合适位置。然后对气动液压泵10泄压，使支撑平台5沿着导向结构凹形卡槽7方向下移，车轮再次落到定位块上被固定后，通过压力机对连接销进行压装，并依此类推，完成车轮所有的连接销的压装。 In the press-fitting process of the wheel connecting pin, the wheel is first placed on the press-fitting platform 3 and positioned by the positioning block 4 . Then move the press mounting platform 3 along the linear guide rail 2 to directly below the press, and press the connecting pin into the mounting hole by the press. After the press fitting of a connection pin is completed, the hollow hydraulic cylinder 9 pushes the support platform 5 upwards by the pneumatic hydraulic pump 10 . The supporting platform 5 will move upwards along the direction of the guide structure concave slot 7, and when it is moved to a proper position, the wheel will break away from the positioning block 4. At this time, the wheel is rotated by the rolling of the roller 8, and adjusted to the next suitable position that needs to be press-fitted with the connecting pin. Then the air-hydraulic pump 10 is depressurized so that the support platform 5 moves down along the concave groove 7 of the guide structure. After the wheel falls on the positioning block again and is fixed, the connecting pin is press-fitted by a press, and according to this By analogy, the press-fitting of all the connecting pins of the wheel is completed.
