Problems solved by technology

[0004] This type of centering machine with a Y2-axis mechanism has a simple structure. When clamping a cylindrical part, the end of the part is fixed by a three-jaw chuck. In order to prevent the part from moving along its own axis, it is necessary to clamp the part tight, thus having greater damage to the surface of the part

Embodiment 1

[0032] Embodiment 1: a kind of clamping device, such as Figure 1 to Figure 2 As shown, the main shaft 1 is included, and a cylindrical tie rod 2 is pierced along the inner axis of the main shaft 1 . The axis of the pull rod 2 is set along the horizontal direction. The pull rod 2 is slidably connected with the main shaft 1 , and a cylinder (not shown in the figure) is fixed on the main shaft 1 , the cylinder includes a piston shaft, and the piston shaft is fixedly connected with one end of the pull rod 2 .

[0033] The main shaft 1 is fixedly connected with the connecting disc 3 . The connecting disc 3 is located at the end of the pull rod 2 away from the piston shaft. The connection pad 3 includes a first support portion 31 and a second support portion 32 .

[0034] The first support part 31 is disc-shaped, and has a through hole 311 along its axis, and a first groove 312 and a second groove 313 along its two end surfaces, and the main shaft 1 is embedded. In the first gr...

Embodiment 2

[0041] Embodiment 2: a kind of mind-taking machine, such as image 3 As shown, a clamping device and a frame as described in Embodiment 1 are included. There is a tool holder built in the frame, and a number of knives are placed on the tool holder, which are rotated by the clamping device to make the tool process the parts.

Abstract

The invention discloses a clamping device. The clamping device is characterized by comprising a main shaft and a chuck fixed to the main shaft; a stop block used for making contact with the end portion of a part is fixed to the chuck; a pull rod is connected to the main shaft in a sliding manner; a clamping head is connected to the chuck; the clamping head comprises a connecting pipe and three elastic blocks which are evenly distributed in the axial direction of the connecting pipe and used for making contact with the outer wall of the part, wherein the connecting pipe and the three elastic blocks are fixedly connected. The ends, back to the connecting pipe, of the elastic blocks incline in the direction away from the stop block, the pull rod is in threaded connection with the connecting pipe, and the sides, back to the part, of the three elastic blocks are in contact with the chuck. In addition, the invention discloses a core passing machine comprising the above clamping device, and the problem that the surface of a part is prone to damage when an existing clamping device is used is solved.

Description

technical field [0001] The invention relates to a numerical control machine tool, more specifically, it relates to a clamping device and a centering machine using the device. Background technique [0002] A CNC machine tool is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions. [0003] At present, the Chinese patent with the publication number CN203817861U discloses a centering machine with a Y2-axis mechanism, which includes a bed and a Y2-axis mechanism, wherein the Y2-axis mechanism is used for end face milling or end face eccentric hole processing on the back of the part, the Y2 The shaft mechanism includes a fixed seat fixed on the body of the centering machine tool, a slide plate slidably connected with the fixed seat, and a power head fixed on the top of the slide plate. There are multiple power tools protruding vertically from the outer surface...
