The utility model belongs to the technical field of a simulation turntable, and in particular relates to a limit mechanism of a simulation turntable.

In production practice, many instruments and equipment are required to rotate 360°. In order not to break the wires connected to the instruments and equipment, the instruments and equipment are usually installed on the simulation turntable, and the installation on the rotating table of the simulation turntable is limited. The position mechanism makes the simulation turntable rotate 180° clockwise or counterclockwise, and realizes the rotation of the simulation turntable within the range of 0°～360°.

A limit mechanism of the simulated turntable is a gear transmission mechanism, and the structure is very complicated.

Another limit mechanism of the simulation turntable is that a stop rod is installed on the rotating table of the simulation turntable, and an elastic stop block is installed on the base. The stop rod is vertically downward and cannot rotate around the installation axis. The simulation turntable Rotate clockwise or counterclockwise, the limit rod fixed on the rotating table of the simulation turntable is limited by the elastic stopper, due to the position of the limit rod, the clockwise or counterclockwise rotation of the simulation turntable cannot reach ±180 °, the simulation turntable can only rotate clockwise or counterclockwise within the range of 0°～330°, and the use of instruments or equipment that requires the simulation turntable to rotate clockwise or counterclockwise within the range of 0°～360° is subject to certain restrictions. limit.

The purpose of this utility model is to overcome the shortcomings of the above-mentioned upper limit mechanism of the simulation turntable, and provide a simulation turntable with reasonable design, simple structure, and the simulation turntable that can make the simulation turntable rotate clockwise or counterclockwise within the range of 0 ° ~ 360 ° 360° azimuth limit mechanism.

In order to achieve the above object, the solution adopted by the utility model is: it includes a left stop lever arranged on one side of the rotating workbench of the simulation turntable, and a right stop lever at a 30° orientation with the left stop lever on the other side, It also includes elastic stop blocks arranged on the base.

The left stop bar of the utility model is as follows: the top, front and rear sides of the left turn bar are provided with a left connecting plate connected with the rotary workbench of the simulation turntable, and a left stop plate is provided on the left side. The right stopper lever of the present utility model is: the front and rear sides of the top of the right turning lever are provided with a right connecting plate connected with the rotary workbench of the simulation turntable, and a right stopper plate is provided on the right side.

Compared with the existing limit mechanism on the simulation turntable, the utility model installs a limit rod on the left and right sides of the simulation turntable at the position of ±15°, an elastic stop block is installed on the base, and the top of the limit rod is set There are two connecting plates, one stop plate, and the elastic stop block stops the left and right stop rods, so that the simulation turntable can rotate 180° clockwise and 180° counterclockwise within the range of 0°～360°.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail, but the utility model is not limited to these examples.

In FIGS. 1-7 , the present embodiment is composed of a left coupling ear 2 , a screw rod 3 , a left stop rod 4 , a right connection ear 5 , a right stop rod 6 and an elastic stop block 7 . On the left side of the rotary workbench 1 of the simulation turntable, a left connecting ear 2 is fixedly connected with a threaded fastening connector, and a right connecting ear 5 is fixedly connected with a threaded fastening connector at an orientation of 30° on its right side. Connect with screw rod 3 or pin movably to be provided with left stop bar 4 on coupling ear 2, be connected with right stop bar 6 with screw rod 3 or pin movably on right link ear 5, left stop bar 4 and right stop bar 6 can Rotate around screw rod 3 or pin. An elastic stop block 7 is installed on the base 8 .

The structure of the left stop lever 4 of the present embodiment is as follows: there is a left connecting plate 4-3 connected with the left turning lever 4-1 at the front and rear sides of the top of the left turning lever 4-1, and the left connecting plate 4-3 is connected with the left turning lever 4-1. Add hole on the plate 4-3, and screw rod 3 or pin can pass in the insertion hole and left stop bar 4 is installed on the left coupling lug 2 of rotary table 1 left side. There is a left stop plate 4-2 connected with the left turn bar 4-1 on the left side at the top of the left turn bar 4-1, and the left stop plate 4-2 makes the simulation turntable rotate clockwise to -180 ° limit position.

The structure of the right stop bar 6 is: a right connecting plate 6-3 connected with the right rotating bar 6-1 is respectively arranged at the front and rear sides of the top of the right turning bar 6-1, and the right connecting plate 6-3 Add hole on the top, screw rod 3 or pin can wear in the hole and right stop bar 6 is installed on the right coupling lug 5 of rotary table 1. There is a right stop plate 6-2 connected with the right turn bar 6-1 on the right side of the top of the right turn bar 6-1, and the right stop plate 6-2 makes the simulation turntable rotate counterclockwise to +180 ° limit position.

The working principle of the utility model is as follows:

When the simulation turntable rotates counterclockwise, as shown in Figure 2 before the stop, the left stop bar 4 and the right stop bar 6 are vertically downward, the simulation turntable continues to rotate counterclockwise, and the right side of the right stop bar 6 hits On the left side of the elastic stopper 7, the right stopper rod 6 rotates clockwise around the screw rod 3, and the simulation turntable continues to rotate counterclockwise, and the right stopper rod 6 is dragged to the upper surface of the elastic stopper 7 as shown in Figure 1. When the simulation turntable continues to rotate counterclockwise, the left stopper rod 4 collides with the left side of the elastic stopper 7, and the left stopper plate 4-2 at the top of the left stopper rod 4 prevents the left stopper rod 4 from going counterclockwise around the screw rod 3. Rotate, at this time, the simulation turntable is limited to the +180° position, and the simulation turntable starts to rotate clockwise. When the simulation turntable rotates clockwise, as shown in Figure 3 before the stop, the left stop bar 4 and the right stop bar 6 are vertically downward, the simulation turntable continues to rotate clockwise, and the left side of the left stop bar 4 hits On the right side of the elastic stopper 7, the left stopper rod 4 rotates counterclockwise around the screw rod 3, the simulation turntable continues to rotate clockwise, the left stopper rod 4 is dragged to the upper surface of the elastic stopper 7, and the simulation turntable continues to rotate clockwise. Clockwise rotation, the right stopper rod 6 bumps into the right side of the elastic stopper 7, and the left stopper plate 6-2 at the top of the right stopper rod 6 makes the right stopper rod 6 unable to rotate clockwise around the screw rod 3. At this time, The simulation turntable is limited to the position of -180°, and the simulation turntable starts to rotate counterclockwise.
