The longitudinal positioning process of the longitudinal clamping set 4 is that the adjusting motor 412 is turned on, the adjusting motor 412 is used for driving the motor rotating wheel 41201 to rotate, the motor rotating wheel 41201 drives the driving pulley 40201 at the upper end of the third driving gear 402 to rotate through the transmission belt 413, because the driving pulley 40201 and the third driving gear 402 are the same rotating shaft, the third driving gear 402 rotates along with the driving pulley 40201, and when the third driving gear 402 rotates, the transmission gear 403 is driven to rotate. The rotation of the transmission gear 403 will bring the swing arm shaft 405 to swing left and right. After the angle of the vertical clamping arm 408 connected with the lower ends of the third driving gear 402 and the transmission gear 403 is adjusted, the vertically installed clamping column 409 connected with the lower end of the vertical clamping arm 408 is tightly attached to the surface of the clamping mold 6, and a layer of soft protective sleeve is arranged on the surface of the vertically installed clamping column 409, so that the abrasion or collision of the surface of the mold is avoided. The general automobile part mould is a regular blending body, if the mould is a symmetrical body, the opening angle of a longitudinal clamping arm 408 connected with the lower ends of a third driving gear 402 and a transmission gear 403 is the same, and the rotation angles of rotating arm shafts 405 at the left end and the right end are also the same, so that a transverse balance mark post 406 can swing to a horizontal position at the moment, and the transverse balance mark post 406 is parallel to a horizontal straight line. Once the transverse balance marker post 406 is inclined and the mold is a regular body, the situation that the clamping process of the longitudinal clamping group 4 has deviation and needs to be recalibrated can be visually judged.

It is worth explaining that, the clamping post 409 and the die clamping plate 311 are all provided with pressure sensors at the contact position with the surface of the clamping die 6, the external processing circuit and the display device of the pressure sensors are omitted and not shown, the sensors are arranged to monitor the clamping degree of the whole clamping structure in the clamping positioning process all the time, the phenomenon that the clamping degree is too large or the clamping force is insufficient is avoided, and the precision of the whole clamping process is guaranteed.

The automatic clamping device has the advantages that the traditional manual clamping operation is replaced by automatic equipment such as a motor, the clamping efficiency is greatly improved, the pressure sensor is arranged on the surface of the clamping, the devices such as the transverse balance mark post, the transverse rod positioning frame and the like guarantee the visual display of the positioning process, and the accuracy of the clamping operation is improved.
