Description

The shoulder hole depth calibrator
Technical field
The utility model relates to a kind of in mechanical processing process, measures the mechanical measuring device of shoulder hole depth dimensions, and this device can be measured the depth dimensions of shoulder hole accurately and rapidly.
Background technology
In mechanical processing process; usually have the processing of shoulder hole; as engine cylinder-body, cylinder cap etc., the measurement of hole depth mainly is to use vernier caliper, when processing shoulder hole; the bottom of each shoulder hole is normally conical; each when the higher part of some shoulder hole depth dimensions accuracy requirements of processing, with the measurement of vernier caliper just can not be on the conical surface accurate in locating, make measuring error too big; can not get reliable data, be not easy to workman's feed next time.If the dimension precision requirement of each shoulder hole is higher, be to finish under normal conditions by operations such as repeatedly processing of operator, measurements, waste time and energy, also there is big measuring error.
Summary of the invention
In order to enhance productivity, to improve measuring accuracy, satisfying the demand of online detection, the utility model provides a kind of shoulder hole depth calibrator.
For this reason, the technical solution of the utility model is as follows: the shoulder hole depth calibrator, mainly form by base, gauge head, measurement axis, block, body, length bar, calibrating device, dial gauge; Body and base link together, and are provided with the measurement axis mounting hole, the dial gauge mounting hole that are parallel to each other on body, are provided with the length bar mounting hole coaxial with the measurement axis mounting hole on base; Measurement axis is installed in the measurement axis mounting hole, measurement axis is stretched out downwards from the hole, gauge head is connected the measurement axis lower end, gauge head is between body and base, dial gauge is installed in the dial gauge mounting hole, block one end is fixed on the measurement axis, and the other end is pressed on the gauge head of dial gauge, makes the gauge head of dial gauge and the gauge head of measurement axis be synchronized with the movement up and down; Upper end in measurement axis is equipped with handle, with pulling the motion that fixed handle can make the measurement axis easy on and off; Length bar, calibrating device are movable parts, and during measurement, calibrating device is used for dial gauge to zero, and length bar is used for inserting the shoulder hole of workpiece.
Length bar described in the technique scheme is the length bar that the lower end has bellmouth, and a steel ball and bellmouth match.
The principle of work of measuring instrument: during measurement measuring instrument is placed on the reference field of measured hole, base lower surface and reference field are fitted, and before the measurement, with calibrating device that the dial gauge school is zero earlier, gauge head resets; During measurement,, choose corresponding length bar according to the diameter of measured hole and the depth dimensions of hole requirement, length bar is put into measured hole,, see the reading of table this moment with gauge head is contacted with the upper surface of length bar, institute's indicating value is a processing allowance value on the dial gauge, thereby obtains the degree of depth in hole.Adopt the lower end to drive the length bar of bellmouth, supporting steel ball, can conveniently measure the bottom is conical shoulder hole.
The beneficial effects of the utility model:
Adding man-hour, the operator can easily fast also measure the process redundancy of hole depth very accurately, obtain the degree of depth in hole, this numerical value can directly instruct processing, allow manipulator lathe person can finish the shoulder hole processing of a ladder, process qualified part fast, saved the time of repeated measurement in the process, feed a feed, improve labour productivity greatly, reduced cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The shoulder hole depth calibrator that is illustrated in fig. 1 shown below, body 7 links together by bolt 14 with base 1, is provided with the measurement axis mounting hole, the dial gauge mounting hole that are parallel to each other on body 7, is provided with the length bar mounting hole coaxial with the measurement axis mounting hole on base 1; In the measurement axis mounting hole, be pressed with lining 3, measurement axis 4 is installed in lining 3 endoporus, measurement axis is stretched out downwards from the hole, gauge head 2 is connected the measurement axis lower end, gauge head 2 is between body 7 and base 1, dial gauge 10 is installed in the dial gauge mounting hole, and block 5 one ends are fixed on the measurement axis by screw 16, and block 5 other ends are pressed in the gauge head 10a of dial gauge
On, make the gauge head 10a of dial gauge and gauge head 2 be synchronized with the movement up and down; In the upper end of measurement axis handle 17 is installed, with pulling the motion that fixed handle 17 can make measurement axis 4 easy on and off; Length bar 8, calibrating device 9 are movable parts, and during measurement, calibrating device 9 is used for 10 pairs zero of dial gauges, and length bar 8 is used for inserting the shoulder hole of workpiece 15.Insert in the aperture lower end of length bar 8, and the step place of length bar 8 contacts the location with place, the bottom of shoulder hole, and being used to measure the bottom is the shoulder hole on plane substantially.
As shown in Figure 1, on measurement axis 4, be provided with annular groove 4a, body 7 is provided with and the perpendicular pin-and-hole of measurement axis mounting hole, backing pin 6, spring 12, plug screw 13 be order installation from inside to outside in pin-and-hole, backing pin 6 withstands on the measurement axis 4, can guarantee measurement axis 4 at reset mode, backing pin 6 is stuck in the annular groove 4a, guarantees reliable reset position.Guaranteeing the reliable reset of measurement axis 4, is for more convenient operation, and it is not the necessary condition that realizes the shoulder hole depth survey, just additional technical feature.
