Embodiment 1

[0028] refer to figure 1 , this embodiment provides an automatic pipe chuck device, which can clamp the inner and outer walls of the pipe at the same time, so as to avoid the deformation of the pipe caused by the uneven force on the inside and outside of the clamping place. Specifically, the device includes a fixed plate 100 and The clamping assembly 200 is a bearing part not installed on the fixed plate 100, and the clamping component 200 is arranged on the fixed plate 100. It should be noted that the clamping components 200 are evenly distributed on the fixed plate 100, so as to clamp the pipe evenly, and the Preferably, four clamping assemblies 200 are provided.

[0029] Further, the center of the fixed disk 100 is provided with a central groove 101 and a radial groove 102 arranged radially along the fixed disk 100, the radial groove 102 communicates with the central groove 101, and the fixed disk 100 is provided with a first hydraulic chamber 103; Holding assembly 200, cl...

Embodiment 2

[0040] The difference between this embodiment and the previous embodiment is that this embodiment provides a driving scheme for the inner clip 203, specifically, the first hydraulic chamber 103 communicates with the radial groove 102 through the first through groove 103a, and the first The push rod 201a is disposed through the first slot 103a.

[0041] refer to Figure 5 and Figure 6 , the bottom block 201 is also provided with a second hydraulic chamber 201c, the second hydraulic chamber 201c communicates with the chute 204 through the second through groove 201d, and the inner clamp 203 includes the second clamp block 203a, the third push rod 203b and the third The piston 203c and the second clamping block 203a are arranged in the sliding groove 204, the third push rod 203b is arranged in the second through groove 201d, and the third piston 203c is arranged in the second hydraulic chamber 201c.

[0042] The bottom block 201 is provided with a groove 201f, the groove 201f c...

Abstract

The invention discloses a pipe automatic chuck device The pipe automatic chuck device comprises a fixed disc and a clamping assembly; a central groove and a radial groove formed in the radial direction of the fixed disc are formed in the center of the fixed disc, the radial groove communicates with the central groove, and a first hydraulic cavity is formed in the fixed disc; and the clamping assembly comprises a bottom block, an outer clamping piece and an inner clamping piece, the bottom block is embedded in the radial groove, a sliding groove is formed in the bottom block, a first push rod is arranged on the outer side of one end of the bottom block, a first piston is arranged at the end of the first push rod, and the first piston is arranged in the first hydraulic cavity. According to the device, the inner side and the outer side of a pipe can be clamped, so that the pipe is stressed in a balanced manner, and after the inner clamping piece makes contact with the pipe, the outer clamping piece and the inner clamping piece clamp the pipe at the same time.

Description

technical field [0001] The invention relates to the technical field of pipe chucks, in particular to an automatic pipe chuck device. Background technique [0002] The laser cutting device uses a high-power-density laser beam to irradiate the material to be cut, so that the material is heated to the gasification temperature and evaporates to form a cavity. As the beam moves to the material, the hole continuously forms a narrow slit to complete the cutting of the material. Cutting, while the existing chuck device is not mature enough for the clamping process of thinner pipes, the focus is on the problem of uneven force on the pipe caused by only clamping the outer wall of the pipe and causing the deformation of the pipe. Contents of the invention [0003] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the...
