Description
Technical Field

Since the detection data is very inaccurate in the free state, many companies now pass the detection after fitting. Because the measuring position is limited, the measuring cannot be performed by adopting a common measuring tool, so that a plurality of companies currently adopt advanced three-coordinate measuring equipment for measurement; however, since the measuring surface is small, the acquisition of the measuring points is difficult and the operation is complex, the measuring mode not only prolongs the production period, but also increases the production cost. ( The working principle of three-coordinate measurement is that in the three-dimensional measurable space range, the three-coordinate measuring machine can detect the workpiece according to a measuring head system, return point data on the surface of the workpiece, calculate various geometric shapes, sizes and other measuring capacity instruments through a three-coordinate software system (such as an AC-DMIS), and can meet various and various shapes of workpieces when the three-coordinate measuring machine is used for measuring the workpiece. Any shape is composed of space points, and all geometric quantity measurements can be attributed to the measurement of the space points, so that the accurate acquisition of space point coordinates is the basis for evaluating any geometric shape. )
Therefore, the company designs a measuring clamp, reduces the complexity of measuring operation, improves the measuring efficiency and reduces the production cost on the basis of ensuring accurate measurement.

Specifically, during detection, the sliding assembly is pushed to the measuring assembly, and the dial indicator is selected as the flow meter; in the process of propulsion, the measuring rod end of the measuring meter is just positioned on the inclined plane of the piston ring, and along with the progress of propulsion, the measuring rod end slides from the outer ring to the inner ring of the piston ring along the radial direction of the piston ring, and the measurement of the height difference on the inclined plane of the piston ring is realized through the change of numbers on the measuring meter.
For example, according to an embodiment of the present disclosure, the to-be-assembled component has a disc shape, on which a plurality of limit posts are disposed; when the piston ring is placed on the assembly to be assembled, the outer ring of the piston ring is subjected to the acting force of inward extrusion of the limiting column, so that the piston ring is fixed; when the piston ring is placed on the assembly to be assembled, and the upper surface of the piston ring is higher than the upper surface of the assembly to be assembled.
For example, according to an embodiment of the present disclosure, one end of the to-be-assembled component can be hinged on the sliding component in a flip manner; the back of the to-be-assembled component is provided with a jacking column capable of adjusting the height, and the jacking column is propped against the sliding component to be supported; the inclined plane of the piston ring can be adjusted to be in the horizontal plane by properly overturning the to-be-assembled component and supporting the to-be-assembled component through the jacking column. Because the inclination angles of different piston rings are different, corresponding adjustment is performed through the jacking columns.
For example, according to embodiments of the present disclosure, the slide assembly is adapted to fit on a lead screw slide rail; a shaking handle is arranged on the corresponding screw rod end at one end of the screw rod sliding rail, and a measuring assembly is fixedly arranged at the other end of the screw rod sliding rail; when the handle is swung, the sliding component, the assembly component and the piston ring are pushed together towards the measuring component. The sliding structure of the sliding assembly is designed.
For example, according to an embodiment of the present disclosure, in the measuring assembly, the gauge is fixed on the lead screw slide rail through a bracket mounting.
For example, according to an embodiment of the present disclosure, the lead screw slide rail includes a slide rail, a lead screw, and a mount; the left end and the right end of the sliding rail are respectively provided with a mounting seat, and the mounting seats are matched with the rail grooves of the sliding rail and are locked and fixed through screws; a screw rod is assembled on the mounting seat at the left end of the sliding rail in a threaded manner; the left end of the screw rod is provided with a shaking handle, and the right end of the screw rod is in threaded fit with the sliding component; a bracket is fixed on a mounting seat positioned at the right end of the sliding rail; the bracket is provided with a vertical post and a cross rod, and the cross rod is provided with a measuring meter through a through hole; the measuring meter is a dial indicator, and the lower sleeve of the measuring meter is locked in the through hole; the cross rod is sleeved with a locking nut in a threaded mode, and the locking nut abuts against the lower sleeve of the measuring meter when the locking nut is rotated, so that locking is achieved. The specific structure of the screw rail is designed.
For example, according to the embodiment of the disclosure, an upper pressing plate is arranged right above the assembly to be assembled and is arranged on an upper telescopic mechanism and a lower telescopic mechanism; the assembly to be assembled is provided with a plurality of electromagnetic units A, and the lower surface of the upper pressing disc is provided with a plurality of electromagnetic units B; the piston ring is a magnetic conduction piece, and when the electromagnetic unit A is electrified, the piston ring is magnetically conducted; when the electromagnetic unit B is electrified, magnetism which is the same as that of the upper surface of the piston ring is generated; when the upper pressure plate is pressed down, the piston ring is pressed and fixed. Under the condition of not directly contacting the piston ring, good pressure is realized, so that the measuring rod end head of the measuring meter can be scratched on the surface of the piston ring; in addition, the pressing mode is non-contact flexible pressing, and compared with the traditional mechanical pressing mode, the pressing mode is not easy to cause serious deformation of the piston ring, so that the inclined plane of the piston ring can be well positioned in a horizontal plane, and the measurement is facilitated.
For example, according to an embodiment of the present disclosure, the upper platen is smaller in size than the assembly to be assembled, and the electromagnetic unit B generates an obliquely outward force on the piston ring when the upper platen is lowered. Mainly makes the piston ring bear downward pressure and outward expansion force.
The general principle of the scheme is as follows: installing the piston ring on the assembly to be assembled, adjusting the angle of the assembly to be assembled, enabling the inclined plane of the piston ring to be in a horizontal plane, and detecting whether the piston ring is qualified or not by measuring the height difference of the horizontal plane; then the piston ring is well fixed; the screw rod sliding rail drives the to-be-assembled assembly and the piston ring to act, so that the lower end of the measuring rod of the measuring meter is scratched by the inclined plane of the piston ring, and the measurement of the height difference of the inclined plane of the piston ring is completed.
For easy understanding, core design points of the present solution are described;
1. changes the traditional measurement mode, simplifies the operation steps, improves the measurement efficiency and reduces the production cost
Whether the piston ring is qualified or not is mainly detected whether the inclined plane angle is in a qualified range or not.
The inclined plane of the piston ring refers to the wide surface of the piston ring, and the width is not more than 6mm, so that the measurement cannot be performed by using a common measuring tool. At present, three-coordinate measuring equipment is adopted, but the measuring equipment is difficult to collect measuring points and is complex to operate due to the small ring width and small measuring surface, so that the measuring period is long, and the production period of the whole piston ring is prolonged.
In this scheme, whether the inclined plane (circle width surface) is qualified or not is detected by detecting the height difference of the inclined plane (circle width surface) near the inner diameter and near the outer diameter. For example, the inclination angle of the piston ring inclined plane is 10 degrees, the qualified inclination angle is 10 plus or minus 0.5 degrees, namely plus or minus 0.5 degrees is an allowable error; according to the scheme, the piston ring is placed obliquely by 10 degrees, and the inclined plane is in a preliminary horizontal state, so that the inclined plane has corresponding allowable height difference at the inner diameter and the outer diameter within an allowable error range of +/-0.5 degrees. According to the scheme, whether the inclined plane is qualified or not is judged by detecting whether the height difference of the inclined plane at the inner diameter and the outer diameter is within the range of the allowable height difference.
In short, the scheme converts the traditional angle error allowable range into the height error allowable range, the corresponding detection device is greatly simplified by the detection mode, the operation difficulty is reduced, the detection efficiency is improved, the production period is shortened, and the production cost is reduced.
2. At the same time ensure good detection precision
In the measuring process of the piston ring, the installation and fixation precision of the piston ring has great influence on the subsequent measuring precision; because the width of the inclined plane of the piston ring is small, the number obtained by detecting the inclined plane is small, and if the installation accuracy is slightly wrong, even if the error is small, the result is reflected to the measurement number, and the influence is also great.
According to the scheme, the piston ring is limited in the circumferential direction through the limiting column simulation piston ring, and simultaneously the piston ring is compressed in a magnetic mode, so that compared with a traditional compression mode through the pressing strip, the compression mode is more uniform in applied pressure, the piston ring can be flattened well, namely, the installation accuracy can be guaranteed, and the follow-up measurement accuracy is guaranteed. In other words, the piston ring with small width is compressed and fixed by magnetism and is compressed in an oblique pressure mode, so that the force applied to the piston ring is more uniform, the piston ring can be better ensured to be in a good form after being compressed, and the installation precision is greatly improved.
In addition, the compaction mode is non-contact compaction, and cannot cause any influence on the contact between the measuring rod of the measuring meter and the inclined plane of the piston ring.
The utility model has the following advantages:
(1) The detection of the piston ring inclined plane is converted into a horizontal plane from the traditional measurement inclined plane, and whether the angle difference value is in a qualified range is reflected by measuring the height difference of the horizontal plane, so that the measurement mode solves the problem that the traditional measurement method and the advanced measurement tool cannot realize;
the novel measuring thought of the scheme ensures that the device for realizing the thought has simple structure and is convenient to operate; and the acquisition point is not needed, so that the measurement effect is improved;
in addition, the whole device has low price, and the device can quickly detect the result of the position when in use, thereby shortening the measurement period; the production period of the whole piston ring is shortened, and the cost is reduced;
(2) The piston ring is very convenient to fix, and the accurate measurement precision is ensured.

The specific structure of the screw rail 6 is designed.
For example, referring to fig. 6, the compression of the piston ring 4 is structurally designed. An upper pressure plate 12 is arranged right above the assembly to be assembled 2, and the upper pressure plate 12 is arranged on an upper telescopic mechanism and a lower telescopic mechanism; a plurality of electromagnetic units A are arranged on the to-be-assembled assembly 2, and a plurality of electromagnetic units B are arranged on the lower surface of the upper pressing disc 12; the piston ring 4 is a magnetic conduction piece;
when in work, the electromagnetic unit A is electrified to lead the piston ring 4 to conduct magnetism; when the electromagnetic unit B is electrified, magnetism which is the same as that of the upper surface of the piston ring 4 is generated; when the upper pressure plate 12 is pressed down, the piston ring 4 is pressed and fixed; under the condition of not directly contacting the piston ring 4, good pressure is realized, so that the measuring rod end of the measuring meter 3 can scratch the surface of the piston ring 4; in addition, the pressing mode is non-contact flexible pressing, and compared with the traditional mechanical pressing mode, the pressing mode is not easy to cause serious deformation of the piston ring 4, so that the inclined plane of the piston ring 4 can be well positioned in a horizontal plane, and the measurement is facilitated.

Mainly the piston ring 4 is subjected to downward pressure and simultaneously to outward expansion force.
