Problems solved by technology

Since there is no clamping device on the top of the workpiece, the workpiece is processed in a cantilever state. During the processing, the workpiece jumps violently in the circumferential direction, which makes it difficult to guarantee the accuracy of the inner hole of the workpiece.

Abstract

The invention aims to provide a workpiece clamping device applied to a horizontal lathe. The workpiece clamping device comprises a supporting baseplate arranged on a lathe surface, wherein two movable brackets are arranged on the supporting baseplate, and support rollers capable of rotating freely are arranged on the brackets. The workpiece clamping device is characterized in that a portal frame is further arranged on the supporting baseplate, vertical plates on two sides of the portal frame are located on the plate surfaces at two ends of the supporting baseplate, adjustable roller devices are arranged on two sides of a top central line of the portal frame respectively, and rollers capable of rotating freely are arranged on the roller devices; and a workpiece is clamped by the two support rollers at the bottom and the two rollers at the top. The clamping device can guarantee the workpiece stability during machining, improves the machining precision, and effectively increases the machining efficiency of the lathe.

Description

[0001] technical field [0002] The invention relates to a workpiece clamping device applied to a lathe, in particular to a workpiece clamping device applied to a horizontal lathe. Background technique [0003] When processing the inner hole of thin-walled cylindrical parts on a horizontal lathe, due to the characteristics of heavy weight, thin wall, and short length, the tailstock of the horizontal lathe cannot be used to fix the workpiece, which greatly reduces work efficiency. At present, the commonly used fixing method is to install a slide plate on the guide rail surface of the bed. There are two movable brackets on the slide plate. The roller holds the lower part of the workpiece for processing. Since there is no clamping device on the top of the workpiece, the workpiece is processed in a cantilever state. During the processing, the workpiece jumps violently in the circumferential direction, which makes it difficult to guarantee the accuracy of the inner hole of the w...
