The valve following quick-change clamp is characterized in that a guide pull rod is arranged on a clamp bottom plate and is perpendicular to the middle head v-shaped block.

The valve following quick-change clamp comprises the clamping plates, wherein the clamping pins, the jacking bolts and the RFID chips are arranged on the top surfaces of the clamping plates, the clamping pins are arranged at the edges of the top surfaces of the clamping plates, four clamping pins are arranged in total, the RFID chips are arranged at the geometric center of the top surfaces of the clamping plates, and the distance between the arrangement positions of the jacking bolts and the RFID chips is one quarter of the side length of the clamping plates.

The valve following quick-change clamp is characterized in that a positioning blind rivet is arranged below the bottom plate of the clamp bottom plate.

According to the valve following quick-change clamp, the two 5-degree bevel angle adjusting blocks are arranged in the two channel v-shaped blocks, the upper bevel angle adjusting block is connected with the adjusting screw, and the screw is used for realizing front-back movement, so that the lower bevel angle adjusting block is extruded, and the height of the valve body is adjusted.

The invention has the remarkable effects that: the workpiece is effectively clamped in the automatic machining process and quickly circulated among the devices, machining auxiliary clamping time is greatly shortened, and repeated positioning accuracy is greatly improved.

Drawings

FIG. 1 is a schematic view of a valve follower quick change fixture of the present invention.

Fig. 2 is a schematic view of the v-block height adjustment principle.

In the figure: 1. the device comprises a middle head v-shaped block adjusting screw, 2, a guide pull rod, 3, a hinge pin, 4, a pressing plate, 5, an RFID chip, 6, a jacking bolt, 7, a grabbing blind rivet, 8, a positioning blind rivet, 9, a middle head v-shaped block, 10, two-channel v-shaped blocks, 11, a supporting upright post, 12, a clamp bottom plate, 13, two-channel v-shaped block adjusting screws, 10-1, an upper bevel angle adjusting block, 10-2 and a lower bevel angle adjusting block.

Detailed Description

The invention is further described below with reference to the drawings and examples.

Three channel v-blocks 9 and 10 (where 10 comprises a symmetrical two channel v-block) are base mounted on a base plate 12 as shown in figure 1, with the top platen 4 being connected by hinge pins 3 to support posts 11. After the valve body is placed in the clamp, the pressing plate 4 covers the valve body to limit, and then the valve body is fixed by the jacking bolts 6.

As shown in FIG. 2, two bevel angle adjusting blocks of 5 degrees are arranged in the v-shaped block, the lower part 10-2 is connected with an adjusting screw (not shown in FIG. 2) and can be moved back and forth by the screw (not shown in FIG. 2), so that the upper bevel angle adjusting block 10-1 is extruded, and the height of the valve body is adjusted. With the principle, the middle head adjusting v-shaped block 9 is connected with the adjusting screw 1 through the guide pull rod 2, and the height of the two side channel v-shaped blocks 10 is adjusted through the adjusting screw 13. In practical application, the valve body is positioned by a valve three-thimble quick clamping station (not shown), so that the centers of three passages of the valve body are at the same height, and then the heights are adjusted through the v-

shaped blocks

9 and 10, so that the valve body is fixedly clamped.

As shown in fig. 1, 4 grabbing blind rivets 7 are installed on the top of the pressing plate, and the blind rivets can be clamped after being ventilated through a zero point positioning disc (not shown) on an external grabbing mechanism (not shown), so that the workpiece is driven to move on each machine table. In addition, the bottom of the clamp is provided with a positioning blind rivet, and a zero positioning disc (not shown) on the workbench of the machine table can be ventilated and then is clamped with the blind rivet, so that the workpiece is fixed on the workbench.

In addition, as shown in fig. 1, the RFID chip 5 is mounted on the platen 9, and the production data information of the mounted workpiece is read for the unique identification of the workpiece in the production process.

The above-described embodiments are intended to illustrate the present invention, not to limit it, and any modifications and variations made to the present invention within the spirit of the invention and the scope of the appended claims fall within the scope of the invention as defined in the appended claims.
