BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a turntable device for testing a test piece, and more particularly to a test device for static and dynamic testing on the same turntable platform device.

For the ozone aging resistance test of vulcanized or thermoplastic rubber (for example, cracking in a predetermined period, time of first cracking, etc.), the standard of ISO 1431-1 is known. The aging test simulates external factors such as sunlight, temperature/humidity changes, and air pollution to cause aging of materials, products, oxidation, embrittlement, discoloration, deformation, and cracking. According to the provisions of the international standard, the rubber test piece is placed in a closed environment for testing, and the test includes static test and dynamic test.

The so-called dynamic test is a test in which the rubber test piece is rotated while being stretched while the aging test is performed. The so-called static test is to first stretch the test piece to a predetermined length, and then place the stretched test piece in the above closed environment (ie, the environment of the aging test), and complete the operation within the specified time. The trajectory shown.

The existing test machines are all static and static tests or dynamic tests. There is no machine that integrates the two on the same turntable platform equipment. Moreover, due to the large difference in the operating state between the static test and the dynamic test, no one has thought about how to properly combine the two.

In view of the above considerations, the inventor of the present invention proposed a turntable device, which can have both static test and dynamic test functions. It is also worth noting that the turntable device of the present invention can simultaneously perform static testing and dynamic testing.

The first turntable and the second turntable are parallel to each other. At least three support shafts are parallel to each other, supported and fixed between the first turntable and the second turntable. The stretching turntable is fixed to the support shaft in a movable manner above and below, and the stretching turntable is disposed in parallel between the first turntable and the second turntable, and the distance between the stretching turntable and the first turntable is adjustable. The first turntable is fixed to the rotating shaft. The gear turntable has an external gear and is mounted to the second turntable. The annular disk has an internal gear and meshes with an external gear of the gear turntable. The first driving motor is coupled to the rotating shaft, drives the rotating shaft to rotate and drives the first turntable to rotate, and drives the second turntable, rotates with the rotating turntable with a common rotating shaft, and drives the gear turntable by the rotation of the second rotating wheel Turn. The casing houses the first turntable, the second turntable, the stretching turntable, the gear turntable, the support shaft, the annular disk surface, the first drive motor, and the annular disk surface is fixed to the casing.

The driving shaft 114 drives the rotating shaft 114 to drive the first rotating disc 110 to rotate, and the second rotating shaft 120 and the stretching rotary table 130 are rotated by the supporting shaft 112. Since the gear turntable 140 is mounted on the second turntable 120, when the second turntable rotates 120, the gear turntable 140 is driven to rotate, and at the same time, the outer gear 140a of the gear turntable 140 and the gear 150a of the annular disk surface 150 Engagement allows each point on the gear turntable 140 to be rotated out of the trajectory as specified by ISO 14-1-1, as shown in Figure 1.

According to the above feature of the present invention, the gear turntable 140 mounted on the second turntable 120 is driven by the gear turntable 140 and the annular disk surface 150 so that every point on the gear turntable 140 can be turned out as ISO 14-1-1. The specified trajectory can be applied to the static test of the test piece. The case of installing the test piece will be explained below.

[When installing the test piece]

The test strip 10 is generally fixed on the test strip holder 50. The test strip holder 50 includes two blocks, an adjustment shaft (length retractable) that is disposed between the two bodies, and the adjustment shaft is adjustable to an appropriate length. And the two blocks are responsible for holding both ends of the test piece 10. In order to facilitate the mounting of the test piece, a fixing device 142 may be provided on the gear turntable 140 for fixing the test strip holder 50. Here, the fixing device 142 may be a fixture such as a jig on the disk surface of the gear turntable 140, a test stand base, etc., or may be a snap mechanism (for example, a card with a concave-convex shape), and a lock. For the structure of the mechanism (for example, by screwing), the test strip 50 is fixed to the disk surface of the gear turntable 140, and the structure and shape thereof are not limited, as long as the test strip 50 can be fixed on the gear turntable 140. .

In other words, the fixture 142 is disposed on the gear turntable 140. The fixing device 142 is, for example, a structure such as the above-described jig, a sample holder base, a snap mechanism, a lock mechanism, or the like for holding the sample holder 50. The test strip 50 is a test stand used in a general strain tensile test, and the number of the test racks 50 is not limited and can be set according to actual test needs. The number of test strips 50 shown in Figure 2 is merely exemplary and should not be construed as limiting the invention.

As can be seen from the description of the previous paragraph, each point of the gear wheel 140 can be rotated out of the trajectory as specified in ISO 14-1-1, so that the test piece fixed in the test strip can be transferred out as ISO14-1- 1 specified trajectory.

[Operation flow description]

[static test]

When the static test is to be performed according to ISO1431-1, the test strip 10 is first held by the test strip holder 50, and after the test strip 10 is stretched by a predetermined length, the test strip holder 50 and the test strip 10 are fixed to the fixing device 142. (provided to the fixture 142 of the gear turntable 140). If a plurality of test strips are to be tested at the same time, it is only necessary to use a plurality of test strips 50, and each of the test strips 50 is used for a special test piece. Of course, the maximum number of test strips 50 that can be held is limited by the area of the gear turntable 140, as long as sufficient clearance is maintained between the test strips 50 so as not to affect the uniform circulation of ozone in the test environment.

Then, the first driving motor rotates 116, the first rotating wheel 120 is rotated, and the second rotating wheel 120 is rotated to drive the gear rotating wheel 140 to rotate, so that the test pieces 10 fixed on the gear rotating table 140 can be turned out as ISO. The prescribed trajectory of 1431-1. As long as the motor speed is properly controlled, a complete trajectory can be completed in 8~12 minutes to meet the static test requirements of ISO 1431-1.

[dynamics test]

Since the dynamic test specified in ISO 1431-1 rotates the entire test strip frame 50 while stretching the test piece 10, when the dynamic test is performed, the unstretched test piece 10 is placed together with the test piece holder 50. The first turntable 110 is between the first turntable 110 and the stretch turntable 130. That is, both ends of the test strip holder 50, that is, the fixed end and the stretched end, are fixed to the first turntable 110 and the stretching turntable 130, respectively. Further, the effect of stretching the test piece is achieved by changing the pitch of the stretching turntable 130 and the first turntable 110. Further, after the unstretched test piece 10 is fixed together with the test strip holder 50, the first drive motor 116 is activated to rotate the rotary shaft 114, and the first turntable 110, the second turntable 120, and the pull are driven. The extension dial 130 rotates together, and at the same time, the distance between the stretching dial 130 and the first turntable 110 changes.

Adjusting the change of the distance between the stretching turntable 130 and the first turntable 110 can be coupled to and coupled with the first drive motor 116 by a screw device (not shown), and convert the rotary motion into an up and down motion, and then drive The rotating turntable 130 is used to adjust the pitch of the stretching turntable 130 and the first turntable 110. Of course, a motor (second drive motor, not shown) may be added to adjust the above pitch by using the added motor.

In order to control the first drive motor and the second drive motor, the turntable device of the present invention may further include a motor control unit (not shown) that controls the rotation of the first drive motor, which is a general motor control unit that controls Motor speed, rotation time, etc. If a second drive motor is also installed, the motor control unit can also be responsible for the control of the first drive motor and the second drive motor.

Of course, in order to meet the test conditions specified in ISO 1431-1, there is also a limit to the environmental state in the chamber being tested (i.e., the enclosed space contained in the housing 118 described above). Therefore, the above-described turntable device further includes an environmental control unit (not shown) connected to the housing 118 and controlling the environmental state within the housing 118. The environmental control unit includes a temperature control unit that controls an environmental state in the housing, a humidity control unit, and an ozone concentration control unit. This is the control unit used in the general aging test and will not be described in detail here.

According to the above features of the present invention, the present invention integrates a static test with complex motion trajectory and a dynamic test with up and down and simultaneous rotation, in one device, that is, the turntable device of the present invention can have both static tests. And dynamic testing capabilities. It is also worth noting that the present invention can perform static test and dynamic test at the same time, that is, as long as the test piece is installed on the upper and lower layers, the lower layer can perform static test at the same time, and the upper layer can also perform static test at the same time. of.
