Detailed Description

The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, spherical piece fixture, including driving cylinder 1, be equipped with mounting bracket 2 on the driving cylinder, be equipped with rotatable first swing arm 3 and the second swing arm 4 that sets up on the mounting bracket, be equipped with first splint 31 on the first swing arm, be equipped with second splint 41 on the second swing arm, first splint and second splint inner wall all are equipped with and are used for the spherical recess 32 with 9 outer wall matched with of work piece, the driving cylinder includes actuating lever 11, the actuating lever with first swing arm one end is connected, the actuating lever with second swing arm one end is connected. The actuating cylinder can be cylinder or pneumatic cylinder etc. drives first swing arm and second swing arm and folds when its actuating lever contracts, and its first splint and second splint centre gripping cooperate in the outer wall of spherical both sides, spherical recess and spherical outer wall, increase area of contact, and the centre gripping is more firm.

The utility model discloses in, as shown in the figure, be equipped with the micro-gap switch 5 that is used for being connected with control mechanism in the mounting bracket, micro-gap switch includes button 51, still include with the ejector pin 6 that the button set up relatively, the ejector pin be used for with the upper end contact of work piece. The microswitch can be connected with a control mechanism through signal connection or a wire, the control mechanism can be a PC or a control circuit board, and when the ejector rod is pressed by the spherical part to push the button, a signal is sent to the control mechanism, so that whether the push button is in place or not can be better known. The mounting frame is provided with a sliding groove 20, the ejector rod penetrates through the sliding groove and is in sliding fit with the sliding groove, the top of the ejector rod is provided with a flange 201, and the tension spring is connected with the flange.

In the present invention, as shown in the figure, the front end of the ejector rod is provided with a contact layer 61 made of elastic material. Is not easy to damage.

In the present invention, as shown in the figure, the contact layer is made of rubber.

The utility model discloses in, as shown in the figure, be equipped with extension spring 21 in the mounting bracket, the extension spring with the ejector pin is connected and is used for the drive the ejector pin support press in on the work piece. When the ejector pin atress, overcome the elasticity of extension spring and contact with the button, this extension spring plays the effect that resets.

The utility model discloses in, as shown in the figure, be equipped with mounting groove 22 on the mounting bracket, be equipped with pivot 23 in the mounting groove, be equipped with on the first swing arm with the articulated complex through-hole 30 of pivot. Simple structure and convenient use.

The utility model discloses in, as shown in the figure, be equipped with connecting axle 111 on the actuating lever, first swing arm with the connecting axle is connected. Simple structure, convenient to use, as the alternative, the structure of second swing arm is the same with first swing arm structure.
