Embodiment Construction

[0011] The specific embodiments of the patent of the present invention are described in detail below in conjunction with technical solutions and accompanying drawings.

[0012] Such as figure 1 As shown, the measuring head 1 is installed on the upper base 5 . The upper seat 5 is connected with the lower seat through two spring leaf supports 2, and the upper seat 5 can reciprocate left and right. When it is in the left position, the measuring head is in the working position. Leaf spring support 2 is made of the leaf spring clamped by the bimetal sheet, and the leaf spring only clamps the middle part of the leaf spring, and the two ends of the leaf spring expose a certain distance for connecting the upper seat 5 and the lower seat 9. The spring leaf has elasticity, and the upper seat 5 can move freely left and right. Because the spring leaf is held by a bimetallic sheet, it can support the upper seat 5 . The spring steel wire 3 presses the boss position of the upper seat 5 to ...

Abstract

The invention discloses an automatic resetting device for a measuring head for measuring gear pitch variation. When the gear pitch is measured, the position of the measuring head is accurately reset. The device consists of the measuring head, a spring sheet bracket, a spring steel wire, a nut, an upper seat, a positioning screw, a rotating shaft, a stop block, a lower seat and a positioning pin; the spring sheet bracket consists of a spring sheet clamped by double metal sheets, is used for connecting a base and the upper seat, and simultaneously plays a role in supporting the upper seat; the rotating shaft is designed with a lug boss structure, fixed on a side plate and driven by a motor to rotate so as to drive the upper seat to move to the right side; and the upper seat is compacted by adopting the spring steel wire, so that the upper seat is compacted on the positioning screw and the positioning position of the measuring head is ensured. The device has simple structure, is convenient for operation and can be used for accurate positioning of the measuring head.

Description

technical field [0001] The invention belongs to the field of precision machinery, and relates to an automatic repeat positioning device for a measuring head used for measuring gear tooth pitch deviation, which is used for precise positioning of the position of the measuring head when measuring the gear tooth pitch deviation. Background technique [0002] Gear is an important basic part in the field of mechanical engineering, and the level of its measurement technology directly affects the machining accuracy of the gear. Tooth pitch deviation is an important precision index of gears. In the process of tooth pitch deviation measurement, the positioning accuracy of the probe directly affects the measurement accuracy of tooth pitch deviation. At present, in gear measuring instruments, the probe positioning mainly uses precision guide rails, and the position of the guide rails is measured by displacement sensors (such as gratings, inductive probes, encoders, etc.), fed back to th...
