Description

Depth gauge
Technical field
The utility model belongs to field of machining more particularly to a kind of depth gauge.
Background technology
In the manufacture of speed changer, the radial blind holes on shifting shaft are a kind of important feature, the depthometer of the radial blind holes It is very little important.Currently, the depth dimensions of radial blind holes are generally measured by three-coordinate instrument, although this measurement method precision It is higher, but testing cost is high, and detection efficiency is low, is unfavorable for batch detection.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of depth gauges at low cost, efficient.
The technical solution of the utility model is as follows:A kind of depth gauge, it is characterised in that:Including bottom plate (1) and to marking block (11), bottom plate (1) bottom is equipped with stabilizer blade (2), is equipped with upper plate (3) in bottom plate upper horizontal, which passes through two Isometry block (4) is arranged side by side from front to back to be fixedly supported on upper plate (3);Spring is equipped between two high blocks (4) vertically (5) and measuring rod (6), wherein:The measuring rod (6) is multi-diameter shaft, and middle part is matched with the sliding eye sliding on upper plate (3) It closes, the major diameter section (6a) of its underpart is limited by upper plate (3) bottom surface, and the gauge outfit of lever indicator (7) and major diameter section (6a) Bottom surface contacts, and the lever indicator is fixed by gauge stand (8) and the bottom plate (1);Spring (5) top surface and measuring rod (6), And driving measuring rod (6) to move up and down using elastic force, the bottom surface of the spring is contacted with adjusting nut (9), the adjusting nut and institute The threaded hole stated on bottom plate (1) is connected;The path section of measuring rod (7) upper end passes through the via on vee-block (10), the mistake Hole is connected to the bottom V-shaped positioning surface (10a), and is placed on the top surface of vee-block (10) when described pair of mark block (11) use.
Before measurement, mark block (11) will be first placed on the top surface of vee-block (10), to mark block (11) bottom surface and measuring rod (6) top surface contacts, and measuring rod (6) can move down at this time, and the amount of moving down is reflected by the reading of lever indicator (7);It surveys When amount, the upper end of measuring rod (6) is inserted into the radial blind holes of shifting shaft, the top surface contact radial blind holes of measuring rod (6) Bottom hole, and the periphery of shifting shaft is contacted with V-shaped positioning surface (10a), measuring rod (6) can move again at this time, mobile quantity Reflected by the reading of lever indicator (7), and twice reading subtract each other be exactly radial blind holes depth.
Using above technical scheme, the utility model can quickly and easily measure the depth of radial blind holes on shifting shaft, inspection It is high to survey precision, it is at low cost, it is suitable for mass detection.
In the present case, the measuring rod (6) is four-part form multidiameter structure, and the spring (5) top is sleeved on measuring rod (6) in the path section of lower end.
In order to reduce frictional force, holding circle (12), the peace on the holding circle are installed in the sliding eye of the upper plate (3) Dress is densely covered with steel ball (13) in hole, and the measuring rod (6) is contacted with these steel balls (13).
Advantageous effect:The utility model can quickly and easily measure the depth of radial blind holes on shifting shaft, accuracy of detection Height, it is at low cost, it is suitable for mass detection.
Description of the drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1, 2, a kind of depth gauge, including bottom plate 1 and to mark block 11,1 bottom of bottom plate be equipped with stabilizer blade 2, It is equipped with upper plate 3 in bottom plate upper horizontal, which is arranged side by side from front to back isometry block 4 by two and is fixedly supported on upper top On plate 3.Spring 5 and measuring rod 6 are equipped between two high blocks 4 vertically, wherein:Measuring rod 6 is multi-diameter shaft, middle part and upper plate Sliding eye on 3 is slidably matched, and the major diameter section 6a of its underpart is limited by 3 bottom surface of upper plate, and the gauge outfit of lever indicator 7 with it is big The bottom surface of diameter section 6a contacts, which is fixed by gauge stand 8 and bottom plate 1.5 top surface of spring and measuring rod 6, and utilize bullet Power drives measuring rod 6 to move up and down, and the bottom surface of the spring is contacted with adjusting nut 9, the adjusting nut and the threaded hole on bottom plate 1 It is connected.The path section of 7 upper end of measuring rod passes through the via on vee-block 10, the via to be connected to the bottoms V-shaped positioning surface 10a, and It is placed on the top surface of vee-block 10 when using mark block 11.
