技术领域technical field

本发明涉及一种夹具，具体地说是一种汽车轮毂机加工过程中三坐标测量使用的定位夹具。The invention relates to a fixture, in particular to a positioning fixture used for three-coordinate measurement in the machining process of automobile wheel hubs.

背景技术Background technique

随着轮毂产品的多样化、差异化，其尺寸大小变化较大，在其完成机加工后需要对几何尺寸进行测量，为保证测量效率，减少装夹时间，提高重复定位精度，同时因为三坐标的量程局限性，降低空间不足带来的测量效率降低。针对以上这种情况，设计一套三坐标专用移动平放轮毂三坐标定位夹具，解决上述问题。With the diversification and differentiation of wheel hub products, their size changes greatly, and the geometric dimensions need to be measured after machining. The measurement range limitation reduces the measurement efficiency caused by insufficient space. In view of the above situation, a set of three-coordinate positioning fixture for three-coordinate special mobile flat wheel hub is designed to solve the above problems.

发明内容Contents of the invention

本发明的目的是要提供一种定位夹具，解决轮毂使用三坐标检测时重复定位精度。The purpose of the present invention is to provide a positioning fixture to solve the repeated positioning accuracy of the wheel hub when using three-coordinate detection.

为了实现上述目的，本发明的技术方案是：移动平放轮毂三坐标定位夹具，由导轨1、滑座2、定位杆3、夹盘4、定位块5、定位槽6、定位销、定位螺丝所组成。In order to achieve the above object, the technical solution of the present invention is: move the three-coordinate positioning fixture of the flat wheel hub, which is composed of guide rail 1, slide seat 2, positioning rod 3, chuck 4, positioning block 5, positioning groove 6, positioning pin, positioning screw composed of.

导轨1两侧设置燕尾槽，配合滑座滑动，呈长条状。滑座2底部设置燕尾槽，配合导轨滑动，呈正方形。滑座2下端的燕尾槽与导轨1的燕尾槽配合连接。定位杆3呈圆柱状，底部带有螺纹，设置在滑座2顶部。定位槽6固定在滑座2上端，反向上使用定位螺丝将夹盘固定在三坐标大理石平台上。定位槽6中间设置通孔槽，呈长条状。Dovetail grooves are arranged on both sides of the guide rail 1, which slide with the sliding seat and are in the shape of a long strip. The bottom of the sliding seat 2 is provided with a dovetail groove, which slides with the guide rail and is square. The dovetail groove at the lower end of the slide seat 2 is matched with the dovetail groove of the guide rail 1. The positioning rod 3 is cylindrical and has threads at the bottom, and is arranged on the top of the sliding seat 2 . The positioning groove 6 is fixed on the upper end of the slide seat 2, and the chuck is fixed on the three-coordinate marble platform by using positioning screws on the opposite side. A through-hole groove is arranged in the middle of the positioning groove 6, which is in the shape of a strip.

夹盘两侧设置减重斜坡，呈大半圆形，用于固定不同尺寸的铝轮毂。定位销设置于滑座与导轨的定位孔，用于连接定位。There are weight-reducing slopes on both sides of the chuck, which are in the shape of a large semicircle, and are used to fix aluminum wheels of different sizes. The positioning pin is arranged in the positioning hole of the sliding seat and the guide rail, and is used for connection and positioning.

实际使用时，先将轮毂背腔朝上，根据产品尺寸放入相应的夹盘凹槽内，气门孔与夹盘11.5mm凹槽重叠起到轴向定位作用，背腔尺寸测量完毕后，将轮毂反转过来，移动至滑座上，使用轮毂法兰面与滑座正面接触，使用定位块将轮毂中心定位，使用定位槽及定位杆与产品窗口配合，起到轴向定位作用。In actual use, first put the back cavity of the hub upward, and put it into the corresponding chuck groove according to the product size. The valve hole overlaps with the 11.5mm groove of the chuck for axial positioning. After the size of the back cavity is measured, place the The hub is reversed and moved to the sliding seat. Use the flange surface of the hub to contact the front of the sliding seat, use the positioning block to position the center of the hub, and use the positioning slot and positioning rod to cooperate with the product window to achieve axial positioning.

本发明在使用三坐标测量平放轮毂时起到快速定位作用。The invention plays a fast positioning role when using three-coordinate measurement to lay the wheel hub horizontally.
