Abstract
The utility model discloses a key slot depth scale, which can directly measure depth of a key sloth and is convenient for use. The key slot depth scale comprises a ruler, an inner frame and a scale frame, wherein the inner frame is connected onto the ruler via a rectangular through groove, and the scale frame is connected onto the inner frame via a T-shaped through groove. One end of the scale frame is provided with a V-shaped measuring surface formed by two measuring legs, the ruler and one end of the inner frame are respectively arranged into corresponding measuring surfaces, one surface of the inner frame is provided with a waist hole shaped window with scale marks, and the scale marks of the surface of the inner frame correspond to scale marks of the ruler.
Description
Technical field
The utility model relates to a kind of keyway pit gauge.
Background technology
Usually, after the keyway processing, because the highest bus of cylindrical has been removed, the measurement of the keyway degree of depth generally can not be adopted the method for direct measurement, but measure earlier the keyway bottom surface to relative bus apart from size, subtract each other with the physical size of known cylindrical, its difference is the actual grade size of keyway again.This method troublesome poeration, the depth dimensions of keyway need obtain by calculating indirectly.
The utility model content
The purpose of this utility model is the deficiency that exists at above-mentioned prior art, and a kind of keyway pit gauge is provided, and this keyway pit gauge need not can directly measure the keyway depth dimensions by calculating, and compact conformation is easy to use.
The technical solution of the utility model comprises chi frame, ruler, described chi frame is socketed on an inside casing by groove set on it, described inside casing is socketed on ruler by groove set on it, symmetrical being provided with by its two relative madial wall in the relative both sides of chi frame constitutes the two measurement pin that a V-arrangement is measured face, one end face of inside casing and ruler is made as corresponding measurement face respectively, has the window of a band scale on the surface wall of described inside casing corresponding to the scale position of ruler.
Described window is a waist-hole type window.
Groove on the described chi frame is a T type groove, and the groove on the inside casing is a rectangle groove.
The utility model keyway pit gauge compact conformation, the measuring accuracy height, easy to use, can directly measure the depth dimensions of keyway.
Description of drawings
Fig. 1 is the utility model structural representation.Fig. 2 and Fig. 3 are a kind of use synoptic diagram of the present utility model.
Embodiment
The utility model is described in further detail in conjunction with the accompanying drawings below by embodiment, and as shown in Figure 1, ruler 3 passes through by rectangle groove set on the inside casing 2 and is socketed on the inside casing 2, and inside casing 2 passes through by the T type groove on the chi frame 1 and is socketed on the chi frame 1.Be provided with ruler 3 and offer a waist-hole type window 2-2 who links with the rectangle groove of inside casing 2 on corresponding inside casing 2 surface wall of one side of scale, waist-hole type window 2-2 be provided with ruler 3 on the scale of the corresponding formation vernier reading of scale system.The relative both sides, one end of chi frame 1 are symmetrical to be connected with two and to measure pin 1-2, and two measure relative two madial walls of pin 1-2 constitutes a V-arrangement and measure face 1-1.Be made as respectively and V-arrangement measurement corresponding measurement face 2-1 of face 1-1 and 3-1 with an end end of measuring corresponding inside casing 2 of pin 1-2 and ruler 3.
Inside casing 2 and ruler 3 are can be respectively corresponding to slidably reciprocate along the T type groove of chi frame 1 and the rectangle groove of inside casing 2, and can lock by the corresponding fastener 5 and 4 that is connected between inside casing 2 and the ruler 3 and between inside casing 2 and the chi frame 1 respectively.
The specification of the utility model keyway pit gauge can be by the measurement pin length of chi frame and the V-arrangement angle that forms and is changed.
A kind of using method of the present utility model is: before measuring the keyway degree of depth, the measurement pin of keyway pit gauge is stuck on the round piece, two measurement pin are contacted with workpiece equably, at this moment assembly such as mobile inside casing, make the inside casing lower end measurement face and the bus of workpiece peak contact and tighten up the fastener of inside casing and chi frame, this process be the keyway pit gauge to " zero-bit ", as shown in Figure 2.Then the keyway pit gauge is stuck in the top of keyway on the workpiece, mobile ruler is measured about the pin direction toward two then and is slightly swung, and the measurement face of ruler is contacted fully with the baseplane of keyway, this moment, the reading value of keyway pit gauge was exactly the depth dimensions value of keyway, as shown in Figure 3.
Claims (3)
1. keyway pit gauge, comprise chi frame, ruler, it is characterized in that described chi frame is socketed on an inside casing by groove set on it, described inside casing is socketed on ruler by groove set on it, symmetrical being provided with by its two relative madial wall in the relative both sides of chi frame constitutes the two measurement pin that a V-arrangement is measured face, one end face of inside casing and ruler is made as corresponding measurement face respectively, has the window of a band scale on the surface wall of described inside casing corresponding to the scale position of ruler.
2. according to the described keyway pit gauge of claim 1, it is characterized in that described window is a waist-hole type window.
