The measuring device comprises a scale holder, a dial gauge, a movable measuring head, the self-locking nut, a positioning measuring cap, a fixed screw nail, a movable measuring rod, a locking device, a fixed sleeve, a microdrum and a lever push rod, wherein the dial gauge is positioned on the side surface of the scale holder; the movable measuring head is positioned at one end of the scale holder; the self-locking nut to be measured is clamped with the positioning measuring cap; the positioning measuring cap is tightly fixed with one end of the movable measuring rod together through the fixed screw nail; the locking device is tightly fixed with the movable measuring rod; the microdrum is sleeved on the fixed sleeve; and the fixed sleeve and the microdrum are positioned on the end surface of the scale holder. The measuring device disclosed by the utility model is simple in design, convenient to manufacture, and the measurement for the necking size of the self-locking nut is accurate, high in efficiency and high in universality.
Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of measurement mechanism of necking size of self-locking nut.
Background technology
At mechanical processing industry, to being widely used in the standard component self-locking nut of the industries such as Aero-Space, boats and ships, its processing specification is many, quantity large, require height, and the accuracy of measurement of its closing in size directly affects the good for delivery of the locking property of product and product.This product closing in dimensional tolerence is multi-control at 0.03mm～0.05mm, and closing in length h is 2mm～3.5mm, and the measuring position is 1/2nd places of closing in length.This size vernier caliper measurement, measuring accuracy does not reach, and sizing is inaccurate, needs repeatedly check and correction to revise to different vernier calipers and different measurement points, affected by ergometry, and measured value differs greatly, and the vernier caliper maintenance cost is also high, and is easy to wear.Measure with outside micrometer, be difficult for finding closing in size minimum point, inefficiency is located inaccurate.Adopt precision measurement equipment unrealistic again to on-the-spot in-process measurement, its cost is high, and efficient is low.
The utility model content
For overcoming defects, the technical problems to be solved in the utility model provides a kind of easy to operate and measure accurately necking size of self-locking nut measurement mechanism.
A kind of measurement mechanism of necking size of self-locking nut, this measurement mechanism comprises: cap, gib screw, movable measuring staff, locking device, fixed sleeving, microdrum, lever push rod are surveyed in chi frame, indicating gauge, movable gauge head, self-locking nut, location; Indicating gauge is positioned at the side of chi frame, and movable gauge head is positioned at an end of chi frame, surveys cap with the location self-locking nut to be measured is clamped; Gib screw will be located an end of surveying cap and movable measuring staff and be tightened together, the fastening movable measuring staff of locking device, and microdrum is sleeved on the fixed sleeving, and fixed sleeving, microdrum are positioned at the end face of chi frame.
The utility model measurement mechanism simplicity of design, easy to make, accurate to the measurement of necking size of self-locking nut, efficient is high, highly versatile.
Description of drawings
Fig. 1 is the structural representation of the utility model measurement mechanism.
Embodiment
The technical solution of the utility model: take general lever-type micrometer as the fundamental measurement utensil, processing and fabricating location is surveyed cap the closing in degree of depth is positioned, adjust the closing in size with gauge block or length bar after, press the lever push rod and can measure.
As shown in Figure 1, but the utility model provides a kind of measurement mechanism of Measurement accuracy necking size of self-locking nut, and it comprises: cap 5, gib screw 6, movable measuring staff 7, locking device 8, fixed sleeving 9, microdrum 10, lever push rod 11 are surveyed in chi frame 1, indicating gauge 2, movable gauge head 3, self-locking nut 4, location.Indicating gauge 2 is positioned at the side of chi frame 1, and movable gauge head 3 is positioned at an end of chi frame 1, surveys cap 5 with the location self-locking nut 4 to be measured is clamped; Gib screw 6 will be located an end of surveying cap 5 and movable measuring staff 7 and be tightened together, locking device 8 fastening movable measuring staffs 7, and microdrum 10 is sleeved on the fixed sleeving 9, and fixed sleeving 9, microdrum 10 are positioned at the end face of chi frame 1.
During measurement, load onto the location and survey cap 5, rotate microdrum 10 to corresponding scale size according to part closing in dimensional requirement, with locking device 8 fastening movable measuring staffs 7, cap 5 is surveyed to shown position in rotation location, fastening gib screw 6, with gauge block or length bar to 2 " 0 " of indicating gauges.The right hand is held chi frame 1, thumb is pressed lever push rod 11, left hand is placed on the location with the self-locking nut crimping end face and surveys on cap 5 locating surfaces, it is basically identical that closing in size positions and lever-type micrometer are measured axis, unclamp lever push rod 11, be adjacent to the location and survey gently rotating part of cap 5 locating surfaces, find indicating gauge 2 minimum dimension positions, can draw the measured value of closing in size by indicating gauge 2 readings.The different size closing in size that the utility model is surveyed 5 pairs of parts of cap by lever-type micrometer in conjunction with the location is measured.
Adopt the utility model measurement mechanism to have the following advantages:
1, this measurement mechanism is simple in structure, makes easily, and measuring accuracy is high, and is easy to use, quick.
2, this measurement mechanism has improved measuring accuracy by lever-type micrometer, and measurement range is wide, adopts the location to survey cap and has realized positional accuracy and locating speed.Survey the measurement of h value with L value realization different product specification and the different closing in sizes of cap by changing the location.
3, this measurement mechanism does not change the measurement function of former measuring appliance.
