Description
Technical Field
The utility model relates to a ball nut testing device, in particular to an outer diameter run-out testing device of a ball nut.
Background
The ball nut is an important part in an automobile transmission system, the structural characteristics of the ball nut are complex, various production requirements are very strict, the ball nut is fixed by taking the outer diameter as a support when being assembled, the screw rod moves in a matched mode through the inner ball channel of the steel ball and the ball nut, and the jumping size of each part of the outer diameter relative to the inner hole can affect the operation performance of the assembled ball nut and even the operation performance of the whole transmission system. Therefore, the runout of the outer diameter relative to the inner hole is an important form and position tolerance requirement, and strict management and control are required in the machining process. However, most of the traditional external diameter run-out inspection methods adopt a CMM three-coordinate detection method, the CMM detection equipment is expensive and complex in detection, the constant temperature and humidity requirements are also met on the detection environment, the ball nut cannot be inspected in real time in a production field, and the detection efficiency and the detection frequency of the CMM detection method are low.

Detailed Description
The utility model is described in further detail below with reference to the accompanying examples.
As shown in fig. 1-2, an outer diameter run-out inspection device for a ball nut comprises a base 1, a nut clamping mechanism, an inspection mechanism and a pushing mechanism are arranged on the base 1, the nut clamping mechanism comprises a first conical head 2 and a second conical head 3 which are coaxially and oppositely arranged, the first conical head 2 is fixed on the base 1, a connecting rod 4 is fixedly arranged on the second conical head 3, the pushing mechanism comprises a push rod 5, a handle 91, a connecting rod frame 92 and a hinge seat 93, a first fixing bracket 11 is fixedly arranged on the base 1, the push rod 5 is fixedly connected with a connector 6 after passing through the first fixing bracket 11, the hinge seat 93 is fixed on the first fixing bracket 11, two ends of the connecting rod frame 92 are respectively hinged with the handle 91 and the hinge seat 93, an ear plate 911 is fixedly arranged on the handle 91, the ear plate 911 is hinged with the push rod 5, a second fixing bracket 12 is fixedly arranged on the base 1, connecting rod 4 passes behind the second fixed bolster 12 to be connected with connector 6 rotation, and inspection mechanism includes lever table 7, and lever table 7 fixes on base 1 and lever table 7's gauge head radially offsets with ball nut 8's outer periphery, can increase lever table 7 on base 1 according to the inspection demand for this verifying attachment can beat the external diameter of a plurality of positions of ball nut 8's outer periphery simultaneously and check.
As shown in fig. 3-4: the process of utilizing this external diameter verifying attachment that beats to carry out the inspection to ball nut 8 does: firstly, a ball nut 8 with a standard specification is taken, one end of an inner hole of the ball nut 8 is abutted against a first conical head 2, then a handle 91 is pulled downwards, a push rod 5 drives a second conical head 3 to move towards the direction of the ball nut 8, the second conical head 3 is abutted against the other end of the inner hole of the ball nut 8, the ball nut 8 is clamped between the first conical head 2 and the second conical head 3, then the position of a lever meter 7 is adjusted, a measuring head of the lever meter 7 is abutted against the outer circumferential surface of the ball nut 8, then the ball nut 8 is rotated, whether the readings of the lever meter 7 are consistent and are near a zero position is observed, if the readings of the lever meter 7 are consistent and are near the zero position, the position of the measuring head of the lever meter 7 is adjusted again until the zero position is successfully corrected, then the handle 91 is pulled upwards, the push rod 5 drives the second conical head 3 to move towards the direction far away from the ball nut 8, taking off the ball nut 8 with the standard specification, clamping the ball nut 8 to be tested by using the method, rotating the ball nut 8, and judging that the product is unqualified if the measured index value of the lever indicator 7 is greater than the rated value; if the index value of the lever indicator 7 is smaller than the rated value, the product is judged to be qualified, and then the ball nut 8 to be tested is taken down by the same method, and the inspection is finished.
