Further, the cross frame is provided with at least three branches, and the end of each branch is in threaded fit with the support piece.
Compared with the prior art, the invention has the following beneficial effects:
according to the invention, the original structure of the lathe is not changed, and the clamping block and the compression block are fixed at the position of the clamping jaw in the barrel-shaped workpiece, so that the position of the compression block propped against the inner wall of the barrel-shaped workpiece always corresponds to the grabbing position of the clamping jaw on the outer wall of the barrel-shaped workpiece, thereby improving the clamping force of the lathe chuck on the barrel-shaped workpiece, improving the stability of the barrel-shaped workpiece during cutting, and avoiding resonance and tremble generated by cutting. Wherein each branch of crossing frame is provided with the support piece that is used for supporting at barrel work piece inner wall, and support piece can play auxiliary stay's effect, prevents to take place to drop at the barrel work piece after cutting between support piece and jack catch, avoids causing the injury to workman or the work piece that cuts, improves work piece finished product quality and machining efficiency.

Detailed Description
The invention will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1 to 3, a thin-walled barrel-shaped workpiece inner hole bracket for a lathe comprises a body, wherein the body comprises a taper sleeve 6 inserted into a main shaft sleeve 9 of the lathe from one side of a chuck 4 of the lathe, and a pull rod 8 inserted from the tail end of the main shaft sleeve 9; the insertion end of the pull rod 8 is in threaded connection with the tail end of the taper sleeve 6, the tail end of the pull rod 8 is provided with a pressing sheet, and the pressing sheet is fixed with a pressing disc 10 at the tail end of the main shaft sleeve 9 through a fixing piece 7; the front end of the taper sleeve 6 is provided with a cross frame 1, the middle part of the cross frame 1 is provided with a tubular piece which is inserted into the taper sleeve 6 and is in sliding fit with the taper sleeve 6, and each branch end part of the cross frame 1 is provided with a support piece 2 which is used for propping against the inner wall of the barrel-shaped workpiece 3; each claw 5 of the chuck 4 is fixedly provided with a clamping block 11 in the barrel-shaped workpiece 3, a fixing piece 7 in threaded fit is arranged on the clamping block 11 in a penetrating mode, and a compression block 12 propped against the barrel-shaped workpiece 3 is in threaded fit at one end of the fixing piece 7 towards the barrel-shaped workpiece 3.
