Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material testing machine in which an operation panel for inputting load conditions and displaying test conditions can be tilted vertically and horizontally.

[0002]

2. Description of the Related Art A material testing machine body has a holding mechanism such as a holding tool for holding a test piece and a load mechanism for loading a test piece held by the gripping tool. Is input from the operation unit of the operation panel that is integrally fixed with, and the test state and test results (load and stroke) are displayed on the display unit provided on the same operation panel.

[0003]

However, in such a conventional material testing machine, the operation panel is fixedly installed on the control device which is integrally installed on the side of the main body of the testing machine. The orientation of the display unit with respect to the operator could not be adjusted. Therefore, depending on the body shape of the operator or the test operation, it may be difficult to operate the switch or the push button, or the display state displayed on the liquid crystal may be difficult to see.

An object of the present invention is to provide a material testing machine in which the direction of the operation panel with respect to the operator can be tilted vertically and horizontally.

[0005]

A material testing machine according to the present invention is directed to an operation panel having an operation section for inputting load conditions and a display section for displaying a test state, that is, for an operator of the operation panel. It can be tilted vertically and horizontally.

[0006]

Function: The direction of the operation panel with respect to the operator is tilted vertically or horizontally depending on the body shape of the operator or the test operation.

EXAMPLE An example will be described with reference to FIGS. Figure 1
In the above, a lower grip 2 is installed on the fixed table 1, and a movable crosshead 3 is horizontally mounted on a pair of unillustrated screw rods in a frame 8 standing on the fixed table 1.
The upper gripping tool 4 is suspended from the crosshead 3 via a load cell 9. Reference numeral 5 is a cross yoke that connects the upper portions of the screw rods. Reference numeral 6 denotes an operation panel having an operation section for inputting load conditions (load speed, maximum stroke, etc.) and a display section for displaying a test state. In FIG. 1, a mounting mechanism 7 is provided on the left side surface of the fixed table 1. It is installed by.

Here, the operation panel 6 includes, for example, a liquid crystal display section for displaying test conditions, test results, operating procedures, and the like, and a touch switch section for pressing the upper surface of the displayed operating procedures to instruct the operation contents. In addition to having a touch panel unit configured in two layers, it can be configured to have another display unit using a light emitting diode and an operation unit including a push button and a dial, but has various other display units and operation units. It may be an operation panel.

The mounting mechanism 7 includes an operation panel mounting block 72 screwed to the left side surface of the fixed table 1 with bolts 71 as shown in FIG. 4, and a bolt 73 on the rear surface of the operation panel 6 as shown in FIG. It has an operation panel mounting block 74 to be screwed, and a substantially L-shaped operation panel mounting arm 75 (FIG. 4) that connects both blocks 72, 74 to mount the operation panel 6 on the main body of the testing machine.

The operation panel mounting block 72 has a hole 72a through which the operation panel mounting arm 75 is inserted,
A slit 72b that opens one side surface of the hole 72a and a lever 72c that operates a shaft portion (not shown) that penetrates the slit 72b and penetrates the slit 72b are provided. Is contracted, and the operation panel mounting arm 75 inserted through the hole 72c is firmly fastened to the block 72.

As shown in FIG. 4, a ring-shaped stopper 76 is provided on one end side of the operation panel mounting arm 75.
Is provided. The stopper 76 contacts the upper surface of the block 72 when the operation panel mounting arm 75 is inserted into the hole 72a of the block 72, and the block 72 reliably receives the weight of the operation panel 6. The height position of the stopper 76 is adjusted vertically when adjusting the vertical position of the operation panel 76.

As shown in FIG. 5, the operation panel mounting block 74 is also constructed in exactly the same manner as the block 72, and the other of the operation panel mounting arm 75 inserted into the hole 72c by rotating the shaft portion with the lever 72c. It is configured to clamp the end to the block 74.

The position and posture of the operation panel 6 attached to the fixed table 1 can be adjusted by the attachment mechanism 7 as follows. The lever 74c is loosened, and the operation panel 6 is rotated about the horizontal axis XH of the operation panel mounting arm 75 as shown by an arrow A in FIG. 3, and the operation surface of the operation panel 6 is tilted up and down with respect to the operator. To do. The lever 72c is loosened, and the operation panel 6 is rotated about the vertical axis XV of the operation panel mounting arm 75 as shown by an arrow B in FIG. 2 or FIG. 3, so that the operation surface of the operation panel 6 faces the operator. Tilt to the left and right. By loosening the lever 72c, the operation panel 6 can be moved up and down as shown by an arrow C in FIG. At this time, the stopper 76
Adjust the position of in advance. The mounting block 72 is mounted on the right side surface of the fixed table 1, and the operation panel 6 is mounted on the right side of the testing machine body by the connecting mechanism 7.

By the above adjustment, the direction and position of the operation panel 6 can be freely changed according to the body shape of the operator and the test operation, the operability is improved, and the display section is easy to see. The tester body is controlled by a control device (not shown), and the operation panel 6 is connected to the control device by a cable (not shown). That is, the operation panel 6 is provided separately from the control device.

The present invention can be applied not only to the testing machine having the structure described above but also to various types of testing machines. For example, it can be applied to a so-called universal material testing machine in which the distance between a pair of upper and lower crossheads is changed and the specimen is loaded. Instead of the lower grip 2 and the upper grip 4, a compression test jig or multiple points can be used. It can also be applied to testing machines that use bending test jigs. Further, the mechanism 7 for mounting the operation panel on the main body of the tester is not limited to the illustrated example, and various types such as a system using a ball joint can be adopted.

In the construction of the above-mentioned embodiment, the main body of the tester is constituted by the fixed table 1, the movable crosshead 3, the frame 8 and the like, and the holding mechanism is constituted by the upper and lower grips 2, 4, and the fixed table 1 and the movable crosshead. The load mechanism is constituted by 3.

[0017]

As described in detail above, according to the present invention, since the orientation of the operation panel can be changed vertically and horizontally, the orientation of the operation panel can be adjusted according to the body shape of the operator and the test operation. Therefore, operability and visibility of the display unit are improved.
