Description

Apparatus for selecting wave-spring < RTI ID = 0.0 >

The present invention relates to a wave spring load automatic measuring device, and more particularly, to a wave spring load automatic measuring device capable of stably supplying a wave spring individually and measuring a load of the wave spring to distinguish between defective and good products.

The wave spring is formed in a coil spring shape in which the bending is continuously repeatedly formed, which can be confirmed by the wave spring perspective view of FIG.

Wave springs are used in various industrial fields, especially for automobile parts, so they require high precision and distinguish good products from defective products within the load range.

Generally, the method of measuring the load of the wave spring has been using a device capable of determining the load by the sensor by pressurization. At this time, the wave spring is manually supplied by the manual worker and measured individually.

In order to solve this problem, a wave spring has been used in which a plurality of wave springs are stacked in the supply pipe, and the wave springs are sequentially pushed in from the lower side. However, there is a problem in that the wave spring shape is bent and mutual interference occurs with the wave spring stacked on the upper side .

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a wave spring load automatic meter capable of stably supplying a stacked wave spring to a load meter without interfering with a wave spring at the upper side The purpose is to provide.

According to an aspect of the present invention, there is provided an apparatus for measuring a load, comprising: a lower frame having a plate horizontally disposed on an upper side thereof; a measurer for measuring a load provided on a central portion of the lower frame; A supply pipe for receiving the laminated wave spring and allowing the wave spring to be supplied to the upper portion of the plate by a free fall method by gravity and having a cutting groove formed at a lower end thereof; A lower plate which is slidably reciprocated on one side of the plate and slidably moves the wave spring supplied to the upper portion of the plate, and a rail which passes through the cutout groove and supports the wave spring inside the supply pipe upward, And a pushing unit, which is composed of a protrusion, for moving the wave spring on the plate to the measuring instrument without interfering with the wave spring inside the supply tube.

The bottom plate has curved cutout grooves corresponding to the circumference of the wave spring at an end thereof to receive the side surface of the wave spring.

The rail protrusion is formed to have an end tapered to induce the rise of the wave spring inside the supply pipe.

The measuring device is composed of a pressure unit which is moved up and down on the plate to press the upper part of the wave spring and a sensor which is provided inside the plate and whose load is measured by the pressure unit.

The lower frame may further include an air unit having a pair of nozzles provided at different angles toward the measuring unit. The air unit is electrically connected to the air unit. The air unit is connected to the sensor, receives a load signal of the sensor, The controller may further include a controller for selectively injecting the nozzles according to a load range or the like, thereby sorting the wave spring according to the load.

According to the present invention having the above-described configuration, the following effects can be expected.

When a wave spring stacked in a supply pipe pushes a spring supplied by a free fall from a lower side to a pushing unit and feeds it to a sorter, the wave spring at the lowermost end is pushed to the lower plate of the pushing unit, The wave spring can be maintained in an upright position in the supply tube, allowing the wave spring to move without mutual interference.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a front view of a wave spring load automatic meter according to an embodiment of the present invention.

Referring to FIG. 2, the wave spring load automatic meter of the present invention comprises a lower frame 100, a measuring instrument 200, a supply pipe 300, and a pushing unit 400.

The lower frame 100 is formed as a pedestal having a frame structure, and the plate 120 is installed in the upper side in the transverse direction, thereby providing a path through which the wave spring S can move horizontally.

The measuring device 200 is a device capable of measuring the load of the wave spring S and is provided at a central portion of the lower frame 100 to measure a load of the wave spring S supplied to the center of the plate 120 It can be measured by pressurization.

The measuring device 200 includes a pressing unit 220 which is moved up and down on the plate 120 to press the upper portion of the wave spring and a pressing unit 220 which is provided inside the plate 120, And a sensor 240 for measuring a load.

The supply pipe 300 can supply a wave spring S to the plate 120 and is vertically spaced from the plate 120. A stacked wave spring is accommodated in the supply pipe 300, and the wave spring S can be supplied to the upper portion of the plate by a free fall method by gravity.

A plurality of cutting grooves are formed in the plate direction at the lower end of the supply pipe 300. The reason why the cutting grooves 320 are formed is that the pushing unit 400 is moved, 300 so that the wave spring S can be supported.

The pushing unit 400 is a device that pushes the wave spring S toward the measuring device 200 to move.

The pushing unit 400 is slidably moved on one side of the plate 120.

3 is a detailed perspective view of the pushing unit.

3, a lower plate 420 for moving the wave spring S supplied to the upper portion of the plate 120 in the horizontal direction and a lower plate 420 for moving the wave spring S on the lower plate 420 are formed on the lower plate 420, And a rail protrusion 440 for supporting the wave spring inside the supply pipe upward.

Here, the lower plate 420 may be reciprocally connected to the pneumatic cylinder.

Thus, there is an advantage that the pushing unit 400 can move the wave spring on the plate to the measuring instrument without interfering with the wave spring inside the supply tube.

The curved cutout groove 422 corresponding to the circumference of the wave spring is formed at the end of the lower plate 420 so as to surround the side surface of the wave spring, .

The rail protrusion 440 protruded from the upper portion of the lower plate 420 is formed to have an end tapered to induce the rise of the wave spring inside the supply pipe.

That is, when the lower plate 420 of the pushing unit 400 pushes the wave spring S at the upper portion of the plate, the rail protrusion 440 prevents the wave spring inside the supply pipe 300 from freely lowering have.

4 is a plan view of a wave spring load automatic meter according to an embodiment of the present invention.

The lower frame 100 further includes an air unit 500 having a pair of nozzles 520 and 540 formed at different angles toward the measuring unit and electrically connected to the air unit. And a controller 600 for controlling the spraying of the nozzles in accordance with a load within a predetermined load range and receiving the load signal of the sensor. The controller 600 selects the wave spring according to the load.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the general inventive concept as defined by the appended claims. Of course, many other variations are possible.
