Detailed Description
The present utility model will be further described in detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the detailed description and specific examples, while indicating the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model. In addition, in the following structures, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the concepts of the present utility model.
In the description of the present utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate an orientation or a positional relationship based on the orientation or the positional relationship shown in the drawings, and are merely for convenience of description of the present utility model and simplification of the description. Rather than indicating or implying that the apparatus or elements herein referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The novel auxiliary device for detecting the performance of the ball screw pair as shown in fig. 1-6 comprises a driving wheel structure 100, wherein a gear 101 is arranged on the periphery of the driving wheel structure 100, and the gear 101 is driven by a belt during testing.
The wedges 200 are connected to the upper platen 400 by one end of the corresponding double threaded bolts 300. The wedge 200 is provided with a bevel 201.
The upper press plate 400 is disposed at one axial side of the driving wheel structure 100, and is fixed to the driving wheel structure 100 by a plurality of link bolts 500.
A nut mounting groove 202 is provided on one side of the wedge 200, and a nut 600 is mounted on the other end of the double threaded bolt 300 and then placed in the nut mounting groove 202. The nut 600 is provided to prevent the double threaded bolt 300 from falling off the wedge 200.
The double-threaded bolt 300 is used for connecting the wedge block 200 with the upper pressing plate 400, and rotates downwards when working, and simultaneously pushes up the wedge block 200 downwards to play a pre-tightening role.
Clamping the nut 600 by the wedge 200 will drive the nut 600 to rotate together when the gear 101 rotates at high speed.
The nut 600 is provided with a first positioning groove 601, and is matched with a second positioning groove 701 on the positioning pin 700 in a positioning way through the first positioning groove 601. The bolts are automatically screwed up by the performance testing equipment.
