Description

Technical Field

[0001] The utility model relates to the technical field of lathe workpiece brackets, in particular to a Doosan CNC lathe workpiece bracket. Background Art

[0002] As an important component for supporting and fixing the workpiece, the workpiece bracket of a CNC lathe involves a variety of engineering and technical considerations and designs in terms of background technology. The workpiece bracket needs to have sufficient strength and rigidity to ensure that it will not deform or vibrate during the processing process, affecting the processing accuracy and quality. Considering that the bracket will be in contact with the workpiece and the tool for a long time, the material needs to have good wear resistance to extend the service life and reduce maintenance requirements. The workpiece bracket design needs to consider the fixing methods of different types of workpieces, such as clamping, clamping or magnetic adsorption. This needs to take into account the shape, size and material of the workpiece. Some workpiece bracket designs allow adjustments to accommodate workpieces of different sizes or shapes. This flexibility can improve the versatility and production efficiency of the machine tool. The flatness and accuracy of the workpiece bracket surface directly affect the processing quality of the workpiece. For high-precision processing, the bracket surface may require additional grinding or processing to ensure flatness, and the bracket positioning system needs to ensure that the workpiece can be accurately positioned and fixed.

[0003] In addition to the chuck and tailstock, the existing lathes only have a center frame as a positioning mechanism. However, the center frame can only be used for supporting and centering, but cannot locate the distance between the end faces of the workpiece. When the workpiece is raised or lowered, the chuck or tailstock is prone to collision with the workpiece, causing varying degrees of damage to the equipment and the workpiece. In severe cases, the equipment may stop running, causing great losses. In response to the above problems, the inventors proposed a workpiece bracket for Doosan CNC lathes to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a Doosan CNC lathe workpiece bracket, including a cylinder body, a chuck, a tubular workpiece and a center frame base, the cylinder body is fixedly installed on the outside of the center frame base, the chuck is fixedly installed on the outside of the center frame base, and a cylinder limit assembly is fixedly installed on the outside of the cylinder body, and the cylinder limit assembly includes a drag plate, a slide, an upper cover and an L-shaped positioning block.

[0006] Preferably, the cylinder body is fixedly mounted on the outside of the base plate, the base plate is movably connected to the T-shaped frame, and the cylinder body is movable outside the base plate.

[0007] Preferably, a second fixing block is fixedly installed outside the base plate, the second fixing block is fixedly connected to the cylinder body, and one end of the cylinder body away from the second fixing block is fixedly connected to the first fixing block.

[0008] Preferably, a drag plate is fixedly mounted on the outside of the cylinder body, and the drag plate is fixedly connected to the L-shaped positioning block.

[0009] Preferably, an upper cover is fixedly mounted on the outside of the base plate, a slideway is provided on the outside of the upper cover, and the L-shaped positioning block slides on the inner wall of the slideway.

[0010] Preferably, the T-block slides outside the center frame base, and the T-frame is fixedly connected to the copper bar.

[0011] Preferably, a first scraping plate is fixedly mounted on the outside of the T-shaped frame, and a second scraping plate is fixedly mounted on the outside of the first scraping plate.

[0012] Preferably, the tubular workpiece moves outside the chuck, and the L-shaped positioning block can fit the tubular workpiece.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, by setting the cylinder limit assembly, the L-shaped positioning block can move up and down in the self-made slideway, blocking the workpiece at the required distance during loading, so that the workpiece will not collide, and the end face of the chuck will also be processed at one time, saving processing time;

[0015] 2. In the utility model, by setting a certain distance between the feeding of the pipe fitting and the chuck end, the workpiece will not collide. Setting a suitable feeding position can ensure that the pipe fitting will not collide or contact with the chuck end when entering the chuck. The end face of the chuck end is used as a one-time processing target, which can reduce repeated clamping and positioning operations on the machine tool. By processing the workpiece at the chuck end at one time, not only can the time waste of multiple clamping and alignment be avoided, but also the idling and downtime during the processing can be reduced.
