A numerical control machining clamping and positioning device for shell parts

Abstract

The invention discloses a numerical control machining clamping and positioning device for shell parts, which comprises a back support platform, two vertically arranged brackets and an upper clamping seat, the upper part of the back support platform is horizontally arranged, and A hollow cuboid-shaped lower sleeve rod is horizontally arranged below one side of the rear support platform, and two upper clamping rails are arranged parallelly above the lower sleeve rod. The beneficial effect of the present invention is: the hydraulic cylinder 3 pushes the hinge 1 and the turning clamping block 1 to turn through the hydraulic shaft 3, and the turning clamping block 1 turns around the hinge 2; The body parts are clamped and positioned more firmly on the device, and the two clamp bars on the upper clamp seat are adjusted left and right to ensure that the device can adapt and clamp shell parts of different widths. The hydraulic cylinder 2. Push the push card plate to move left and right, turn over the pressure block and turn it over to adjust, so as to ensure that the position of the device for clamping and positioning shell parts of different widths and sizes is more accurate and firm.

Description

technical field [0001] The invention relates to a clamping and positioning device, in particular to a numerically controlled processing clamping and positioning device for shell parts, belonging to the technical field of clamping and positioning devices. Background technique [0002] There are many kinds of shell parts, such as the side wall of the car shell, electrical shell components, etc. During the CNC machining process of the shell parts, the clamping and positioning device is indispensable, and the shell parts are clamped by the clamping and positioning device Fixed to ensure that the shell parts are more stable and reliable when being processed, and improve the precision of the shell parts being processed. [0003] There are still many deficiencies in the existing NC machining positioning device for shell parts in use. The existing clamping and positioning device is not firm enough for shell parts, and can only be used for the same width, The clamping and positionin...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing clamping and positioning device is not strong enough for clamping the shell parts, and can only clamp and position the shell parts of the same width and size, and the adaptability range of the work is small ;The clamping and positioning device has a low accuracy for clamping and positioning the shell parts; the area and range covered by the clamping of the shell parts are too small, resulting in extremely low stability of the shell parts when they are CNC machined, which seriously affects the shell parts. The quality of processing; the problem that the clamping and positioning device is not convenient and fast for the clamping and positioning of shell parts, and a numerically controlled machining clamping and positioning device for shell parts is proposed
