The present invention relates to a gauge for measuring whether the inner or outer diameter of a workpiece is a good or defective product, and more specifically, the upper and lower limits of the inner and outer diameter standards of a measurement object can be integrated and measured in one direction of the measuring plug. The present invention relates to an integrated gauge for measuring internal and external diameters, and to a measurement system using the same, which improves convenience and reliability of measurement and minimizes deformation and wear.

In general, gauges are used to measure the inner or outer diameters of workpieces produced at the production site, such as automotive parts processing and processed products having diameters produced in all parts of the manufacturing processing industry.

Most of these gauges are micrometers, cylinder gauges, dial gauges, vernier calipers and the like.

However, these gauges are used to measure the correct dimensions of the inner or outer diameter, and are not suitable for the self-inspection (product inspection) that checks whether the inner or outer diameter of the processed product meets the specifications as in the present invention.

The gauge used for such self-inspection is judged as good or defective product only by judging whether it meets the specified standard.Therefore, it is not necessary to accurately measure the dimension. Also, the efficiency of production should be considered by simplifying the structure as much as possible to increase the measurement speed. .

However, the conventionally disclosed self-checking gauges are installed on both ends of the measuring plug facing each other and measuring the upper and lower limits of the standard to determine whether the inner or outer diameter of the measured object is a good or defective product. In order to measure twice while turning the measuring plug, the measurement work is inconvenient as well as the measurement time is long, there is a disadvantage that the productivity is reduced.

In addition, since these conventional gauges are mainly solid, that is, the inside is filled, large diameters are heavy, so they are not easy to store or move and occupy a large amount of storage space. There is an inconvenience that does not fall easily, resulting in a decrease in productivity.

In particular, in the case of using a gauge of the conventional circular cylinder solid body, a new manufacturing must be made every time the product of the outer diameter is different, in this case, the manufacturing cost of the gauge was expensive.

The present invention was created to solve this problem in consideration of all the problems of the gauge for measuring the internal and external diameters of the conventional workpiece as described above, and it is possible to check whether the internal diameter or the external diameter of the processed product having the diameter meets the standard. In this case, the upper and lower limits of the inner and outer diameters can be measured together with the operation of the measuring plug in one direction to improve the convenience and productivity of the measurement, as well as to improve the reliability of the measurement using the three-point contact method. Its main purpose is to provide an integrated gauge for measuring internal and external diameters and a measuring system using the same, which prevents pinching, and is light in weight, making it easy to transport, store and use, and minimize deformation and wear.

The present invention, in order to achieve the above technical problem, the main body; An operation cylinder fixed to one surface of the main body; A cylinder rod connected to the operation cylinder and installed through the main body; A measuring plug assembled at an end of the cylinder rod; A triangular measuring plate fixed to the measuring plug, a measuring rod vertically projected from each vertex of the measuring plate, and formed on an outer surface or an inner surface of the measuring rod, and having a step for distinguishing the upper limit measurement part and the lower limit measurement part. An integrated gauge for measuring internal and external diameters consisting of an external diameter gauge or an internal diameter gauge is provided.

The measurable range of the integrated gauge for measuring internal and external diameters is in the range of 1 to 500 mm, and can be used for quality inspection of mass products.

At this time, it is also characterized in that the cylindrical guide to which the cylinder rod is fitted is further provided on the operation cylinder facing surface of the main body.

In addition, a support for height adjustment in the vertical direction is fixed to one side of the lower surface of the main body, and one side of the support is characterized in that the forward and backward cylinder for moving it is installed in parallel with the operation cylinder.

In addition, a pair of guide rods are fixed to one surface of the support with the front and rear vibration cylinders interposed therebetween, and the guide rods are also disposed through the guide blocks.

In addition, the front end surface of the measurement rod is characterized in that the contact sensor is embedded.

Furthermore, in order to achieve the above technical problem, the present invention is a type of microprocessor, and a controller with a built-in memory; A gauge driver connected to the control unit and controlling operation of an operation cylinder or a forward / backward cylinder; An integrated gauge connected to the gauge driving unit and configured to measure whether the inner diameter or the outer diameter of the measured object conforms to a standard; A sensor part embedded in the measurement rod front end surface of the integrated gauge and installed to communicate with the control unit to block operation of the gauge driver when transmitting a signal; A display unit connected to the control unit and displaying a measurement result of the integrated gauge; Provided is a measurement system using an integrated gauge for measuring inside and outside diameters consisting of a keypad-type input unit for inputting information required for setting to the control unit.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

1 is an exemplary perspective view of an integrated gauge according to the present invention, Figure 2 is a cross-sectional view of the main portion of the integrated gauge according to the present invention, Figure 3 is a block diagram of a measuring system using the integrated gauge according to the present invention.

First, the integrated gauge according to the present invention is illustrated in Figs. 1 and 2, (a) is illustrated an integrated gauge for measuring the outer diameter, and (b) is an integrated gauge for measuring the inner diameter.

In this case, the reference numerals given to these gauges are given the same numbers when performing the same function regardless of the inner and outer diameters, and the case of the diameter measurers having different structures will be described with different drawing numbers.

Referring to the illustrated drawings, the integrated gauge according to the present invention includes a body (100).

The main body 100 is preferably formed in a substantially rectangular frame, and in some cases, may be a box-shaped rectangular parallelepiped, but more preferably, the upper and lower surfaces are formed in an open rectangular frame to reduce weight and material.

And, any one surface of the main body 100 is provided integrally to protrude the cylindrical guide 110.

The cylindrical guide 110 plays a role of minimizing operation failure by securing the straightness of the cylinder rod 130 to be described later.

In addition, an operation cylinder 120 is installed on one surface of the main body 100, preferably an opposite surface of the cylindrical guide 110, and a cylinder rod 130 is connected to the operation cylinder 120.

At this time, the cylinder rod 130 is inserted through the main body 100 to the cylindrical guide 110 and is disposed to be exposed to the outside, the operation cylinder 120 may be used hydraulic or pneumatic.

In addition, the measurement plug 140 is fixed to the exposed end of the cylinder rod 130, the outer diameter measuring member 150 or the inner diameter measuring member 160 is fixed to the measuring plug 140.

Here, the outer diameter measuring member 150 and the inner diameter measuring member 160 is preferably made of a three point (three blade) contact measuring method.

In addition, since the outer diameter measuring member 150 and the inner diameter measuring member 160 may vary depending on the size of the measurement object, the outer diameter measuring member 150 and the inner diameter measuring member 160 may be installed to be disassembled and assembled from the measuring plug 140. Each of the plurality of outer diameter gauges 150 and the inner diameter gauges 160 may include a plurality of fixed measuring plugs 140, and the measuring plugs 140 may be installed to the cylinder rod 130 in a replaceable manner.

To this end, these measuring members 150 and 160 have a substantially triangular measuring plate 152 and 162, and measurement rods 154 and 164 protrude from each vertex of the measuring plate 152 and 162.

Thus, the measurement rods 154 and 164 preferably maintain an angle of approximately 120 ° to each other.

In this case, the measurement rods (154, 164) is preferably formed to protrude perpendicularly to the surface toward the front of the measuring plate (152,162).

In addition, a step 156 is formed on an inner surface of the measurement rod 154 formed on the outer diameter gauge 150 among the measurement rods 154 and 164, and a portion where the step 156 is low has an upper limit on the size of the aperture to be measured. The upper limit measurement part 158a which measures is performed, and the part with high step | step 156 comprises the lower limit measurement part 158b which measures the lower limit of the diameter of a diameter.

On the other hand, the step 166 of the measurement rod 164 formed on the inner diameter measuring instrument 160 of the measurement rods 154 and 164 is formed on the outer surface, and the part where the step 166 is low is the standard for measuring the lower limit of the standard size of the aperture. The lower limit measuring unit 168b is formed, and the portion having the high step 166 forms the upper limit standard measuring unit 168a for measuring the upper limit of the standard size.

As such, since the integrated gauge according to the present invention is capable of measuring the upper and lower limits of the specification at one measurement plug 140 at the same time, the convenience of the measurement is extremely improved and the measurement time is shortened.

On the other hand, the integrated gauge according to the present invention may be added to the additional means to maximize the convenience of use thereof.

For example, as shown in (a), (b) of Figure 1, one side lower end of the main body 100 can be fixed to the support 200, and this support 200 and the operation cylinder 120 and the above-described Forward and backward cylinders 210 may be connected in parallel, and guide blocks 220 and guide rods 230 may be installed at both sides of the forward and backward cylinders 210 as necessary.

At this time, the support 220 may have a structure that can adjust the installation height of the main body 100 to facilitate the alignment with the object to be measured, the means for implementing the known rack and pinion In addition, various forms such as LM guides are possible.

In addition, the forward and backward cylinder 210 and the guide block 220 is fixed to the installation surface, connected to the forward and backward cylinder (not shown) 210 and the forward and backward rod (not shown) fixed to the support 220 is The support rod 200 is moved forward and backward, and the guide rod 230 moves along the guide block 220 to allow the support 200 to linearly reciprocate without flow.

Therefore, since the main body 100 can be moved back and forth by the support 200, for example, the main body 100 is measured to have a short or inevitable operation stroke of the cylinder rod 130 connected to the operation cylinder 120. This can be useful if you need to get close to water.

In addition, although not illustrated, in this case, the guide means having the same shape as the guide rail may be further disposed on the bottom surface of the support 200 to smoothly move forward and backward of the support 200.

Integrated gauge according to the present invention made of such a configuration can implement a measurement system through the circuit configuration as shown in FIG.

That is, the measuring system according to the present invention, as shown in Figure 3, a microprocessor and a control unit 300 having an internal memory, and a gauge connected to the control unit 300 and controls the driving of the integrated gauge (G) A sensor (not shown) attached to the front end surface of the measurement rod and the outer diameter measuring gauge and the inner diameter measuring gauge constituting the integrated gauge G, such as a contact sensor, and a sensor connected to the controller 300. The display unit 330 connected to the control unit 300 and the control unit 300 to display a signal of the unit 320, the good value OK and the defective item NO measured through the integrated gauge G are required. It consists of an input unit 340 in the form of a keypad to input the settings and the like.

At this time, the display unit 330 and the input unit 340 is preferably provided in the form of a panel (P) assembled in the enclosure.

The working relationship of the present invention made of such a configuration is as follows.

When the measurement object is determined, and the size of the gauge corresponding to the standard to be measured is selected, the outer diameter measuring member 150 or the inner diameter measuring member 160 meeting the corresponding standard is set in the measuring plug 140.

This state will be understood that the main body 100 is already installed in the measurement position, the measurement object can be inspected whether the inner or outer diameter corresponds to the standard while moving intermittently or continuously.

In this case, as a means for continuously processing the measurement object may be a known roller table or a conveyor belt.

When the measured object to be measured is loaded and reaches the standby state, the controller 300 causes the integrated gauge G to flow through the gauge driver 310.

That is, the operation cylinder 120 is operated in response to the signal of the gauge driver 310, whereby the measurement rod of the outer diameter measurer 150 or the inner diameter measurer 160 fixed to the end while the cylinder rod 130 moves forward. The measurement rod 154 of the outer diameter measurer 150 is inserted when the diameter of the measured object is measured, for example, the outer diameter measurement, and the measuring rod 164 of the inner diameter measurer 160 is inserted when measuring the inside diameter. .

Here, the determination of the quantity (good) and the quantity (good) of the aperture size through the measurement rods 154 and 164 is performed when the upper limit measurement unit 158a of the measurement rod 154 enters in the case of external diameter measurement. If the lower limit measurement part 158b of the measurement rod 154 enters, it will determine that it is defective, and when it does not enter, it determines with good quality.

In this case, a sensing means such as a photo sensor is embedded in the upper and lower limit measuring unit 158a and the lower limit measuring unit 158b and connected to the control unit 300 to display the determination result of both parts. 330) would be better configured to automatically check in real time.

In addition, the upper limit measurement unit 158a to the lower limit measurement unit 158b of the measurement rod 154 are inserted into the diameter of the measurement object due to various causes such as the bending deformation of the cylinder rod 130 and the poor loading position of the measurement object. If it fails to contact the edge portion, the sensor (not shown: described as being installed on the distal end surface of the measurement rod) described above immediately detects this and transmits the detection signal to the control unit 300 through the sensor unit 320. By stopping the driving of the gauge driver 310 by transmitting, it is possible to control to automatically terminate or wait for the measurement work until repair or further action is taken.

When the measurement target aperture of the measured object is the inner diameter, the measurement rod 164 of the inner diameter measurer 160 is driven. In this case, the measurement rod 164 is operated in the same manner as the outer diameter measurement rod 154 described above.

That is, the cylinder rod 130 is advanced by the operation of the operation cylinder 120, and the measurement rod 164 of the measuring plug 140 attached to the end enters the inner diameter of the object to be measured. Contrary to the measurement, if the upper limit measurement unit 168a enters, it is judged as defective or not good, or if the lower limit measurement unit 168b is entered, it is judged good or poor.

In addition, the matter regarding the installation of the sensor means for automatically implementing the determination of such quantity and part is the same as the case of the outer diameter measurement mentioned above.

In this way, the measuring rods (154, 164) that can measure both the upper and lower limits of the standard in one measuring plug 140 can be easily and easily measured in a short time in the quantity and part according to the standard through a single operation Will be.

In addition, it is possible to easily determine whether the inner diameter or the outer diameter of the measurement object having various shapes conforms to the standard through the height adjustment and the forward and backward motion of the main body 100, such as measuring the effective diameter of the tap hole of the bolt. Can be.

In addition, since the integrated gauge according to the present invention is a three-point (three-blade) contact method, it is possible to determine the quantity and part of the more accurate standard, which improves the measurement reliability. It is designed to stop so that there is little wear or deformation of the measuring device.

As described in detail above, the integrated gauge for measuring internal and external diameters and the measuring system using the same according to the present invention provide the following effects.

First, it is convenient to use and can be measured continuously in one direction, which is not cumbersome.

Second, it is light and the measurement time is shortened.

Third, it is possible to automatically reduce labor costs.

Fourth, the production cost is low, because the three-point (three-blade) contact method is eliminated jamming phenomenon.

Fifth, the volume of storing and storing the gauge can be reduced, and its field of application is vast.
