Abstract
The invention discloses a taper empty avoiding type ejector sleeve inner hole length measuring device which comprises a sliding block guiding seat, a measuring sliding block capable of moving relative to the sliding block guiding seat is arranged on the sliding block guiding seat, a measuring part fixing plate is fixedly arranged on the measuring sliding block, and a positioning block used for fixing a product is further fixedly arranged on the sliding block guiding seat. The measuring part fixing plate is provided with a measuring sleeve capable of being inserted into an inner hole of the product, an ejector pin is inserted in the measuring sleeve, the end, inserted in the inner hole, of the measuring sleeve is provided with at least one movable steel ball moving relative to the measuring sleeve, and the end, inserted in the measuring sleeve, of the ejector pin is in a conical shape. Due to the fact that the ejector pin with the taper is matched with the measuring sleeve with the end provided with the steel ball, when the ejector pin moves to the termination position of an effective cylindrical inner hole of an ejector sleeve along with the measuring sleeve, due to the fact that the hole diameter begins to become larger, the limitation on the ejector pin by the steel ball disappears, so that the position of the ejector pin relative to the measuring sleeve is changed, the taper empty avoiding section starting position of the taper empty avoiding type ejector sleeve is found out, and the effective length of the inner hole of the taper empty avoiding type ejector sleeve is accurately obtained.
Description
Technical field
The present invention relates to a kind of tapering empty avoiding type ejector sleeve endoporus length-measuring appliance, belong to Machining Technology field.
Background technology
The endoporus effective length size detection mode of the tapering empty avoiding type ejector sleeve now usually adopted is as follows: use a bar footpath to insert from empty avoiding end 21 than the measurement round bar in endoporus effective sector hole footpath monolateral greatly 0.01, until cannot continue deeply, measure inserting paragraph length value " L1 ", so total long value " L " of ejector sleeve product and algebraic difference of measurement round bar inserting paragraph length " L1 ", be then the proximity values of ejector sleeve endoporus 22 effective length size value " L2 ", i.e. L2 ≈ L-L1; Specifically as shown in Figure 5.
The weak point of this measuring method is: the first, and which need make the measurement round bar (specification comprises diameter of bore and total length) of dimension according to different specifications, and cost waste is large; The second, measuring process is many, and finally separately just need can draw testing result through calculating, and testing result is not directly perceived; 3rd, as shown in Figure 5, algebraic difference " L-L1 " is proximity values, and effectively long there is some difference with reality, and when product empty avoiding section tapering is less, this difference value is larger.
