The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 4, a turning attachment for a guide ring according to an embodiment of the present invention includes: a ring body 100, both ends of which are respectively provided with a clamp groove 110 for embedding a three-jaw chuck of a lathe and a mounting groove 120 for mounting a guide ring 400; a limit screw hole 130 is arranged on the outer peripheral side of the mounting groove 120; the limiting bolt 200 is in threaded connection with the limiting screw hole 130 and can axially limit the guide ring 400; the limit bolt 200 is sleeved with the pressure plate 210, and the pressure plate 210 can be driven to press the guide ring 400 in the mounting groove 120 by screwing the limit bolt 200. The three-jaw chuck of the lathe is a common three-jaw chuck, and the ring body 100 is made of a rigid material, such as steel or iron; because the guide ring 400 is made of nylon and is a thin-walled piece, and the middle of the guide ring is provided with a through hole, the guide ring 400 is difficult to clamp when being directly clamped by the three-jaw chuck, and the guide ring 400 may be dislocated in the rotation process of the lathe, so that the machining precision does not meet the standard. Through setting up solitary anchor clamps, can avoid guide ring 400 to be pressed from both sides by the three-jaw chuck in the course of working and warp and lead to machining error, also can improve the installation effectiveness effectively simultaneously, promote process velocity. The guide ring 400 is circumferentially limited and the pressing plate 210 is axially limited through the limiting bolts 200, so that the structure is simple and the guide ring is convenient to disassemble and assemble.

Further, mounting groove 120 is the ladder groove, and the periphery wall of guide ring 400 is equipped with the shaft shoulder, and guide ring 400 part stretches into the ladder inslot and contacts with the ladder surface of mounting groove 120, and the shaft shoulder contacts with the terminal surface of ring body 100, and clamp plate 210 is used for compressing tightly guide ring 400 in mounting groove 120. The pressing plate 210 is a rectangular plate, the pressing plate 210 is sleeved on the limit bolt 200 and can slide along the limit bolt 200, and when the pressing plate 210 abuts against the guide ring 400, the pressing plate 210 is ensured not to enter the through hole in the middle of the guide ring 400, so that the turning tool is prevented from rotating to cause obstruction.

In some embodiments of the present invention, three insertion grooves 111 are formed in the chuck slot 110 for the three-jaw chuck to be inserted into, and a limit protrusion 112 is formed on a wall of the insertion groove 111.

In some embodiments of the present invention, the guide ring 400 is provided with a positioning groove 410 at the outer circumferential side thereof, and the stopper bolt 200 can be partially inserted into the positioning groove 410 to circumferentially stopper the guide ring 400. Specifically, the outer peripheral wall of guide ring 400 is provided with 6 constant head tanks 410 at even interval, and spacing bolt 200 is equipped with threely and can partly imbed in constant head tank 410 to restriction guide ring 400 and ring body 100 take place relative rotation.

In some embodiments of the present invention, the outer peripheral wall of the ring body 100 is provided with a protruding hole column 140, the hole column 140 is provided with an adjusting screw hole 141, the adjusting screw hole 141 penetrates the hole column 140 and is in threaded connection with an adjusting bolt 300, and the adjusting bolt 300 is used for abutting against the pressure plate 210 to perform stroke limitation on the limiting bolt 200. Because the guide ring 400 is made of nylon material, excessive screwing of the limit bolts 200 may cause the pressure plate 210 to crush and deform the guide ring 400, so that the diameters of the circular holes in the guide ring 400 after being processed are inconsistent, the processing precision is affected, or the guide ring 400 is damaged, and therefore a stroke stop needs to be set for the limit bolts 200, and the guide ring 400 cannot be pressed to deform while the pressure plate 210 can limit the guide ring 400. In addition, the adjusting bolt 300 is provided in a structure in which the length extending out of the ring body 100 can be adjusted in order to accommodate guide rings 400 having different lengths.

In some embodiments of the present invention, the limiting screw holes 130 are spaced a plurality of times around the edge of the ring body 100, and the hole pillars 140 are disposed a plurality of times corresponding to the limiting screw holes 130; the hole column 140 is arranged outside the limit screw hole 130.

In some embodiments of the present invention, the adjusting bolt 300 is sleeved with an indicator 310 for facilitating to view a moving distance of the adjusting bolt 300, and the moving energy of the adjusting bolt 300 drives the indicator 310 to move, so as to ensure that the plurality of adjusting bolts 300 extend out of the adjusting screw holes 141 by a consistent length. Specifically, as shown in fig. 1 to 3, since the adjusting bolts 300 are provided in plurality, it is important to ensure that the lengths of the adjusting bolts 300 extending out of the adjusting screw holes 141 are consistent, and the lengths of the adjusting bolts 300 extending out of the adjusting screw holes 141 are accurately controlled by the setting indicator 310, so that the lengths of the adjusting bolts 300 extending out of the adjusting screw holes 141 are effectively ensured to be consistent, thereby ensuring the machining accuracy of the guide ring 400.

In some embodiments of the utility model, the peripheral wall of the bore 140 is provided with an axially extending ruler groove 142; the indicator 310 comprises a fixedly connected collar 311 and a scale 312, and the adjusting bolt 300 comprises a fixedly connected head 302 and a shaft 301; the lantern ring 311 is sleeved on the rod body 301 and abuts against the head 302, and the movement of the adjusting bolt 300 can drive the lantern ring 311 to move; the scale 312 is slidably mounted in the scale groove 142, and a scale line is marked on one side of the scale groove 142. The two scales 312 are symmetrically arranged on two sides of the sleeve ring 311, and the scales 312 are connected to the outer peripheral wall of the sleeve ring 311; the two scale grooves 142 are also provided corresponding to the two scales 312. The provision of two scales 312 is on the one hand more stable, while the two scales 312 are redundant to each other.

Further, the one end that the scale 312 kept away from the lantern ring 311 is equipped with obvious mark, for example mark red or the cover is equipped with the bright-colored sign of colour, through the scale mark of comparison ruler groove 142 one side, can clearly know the distance that scale 312 removed to the realization is to a plurality of adjusting bolt 300 more accurate regulation.

In some embodiments of the present invention, an indication spring 320 is further sleeved on the shaft 301, two ends of the indication spring 320 respectively abut against the collar 311 and the end wall of the hole column 140, and the indication spring 320 is used for pressing the collar 311 against the head 302. Specifically, as shown in fig. 2 and 3, the indicating spring 320 is provided in the middle of the two scales 312. The indicator spring 320 should normally be always in a compressed state, so as to press the collar 311 against the head 302 of the adjusting bolt 300, thereby ensuring that the indicator 310 can be moved with each rotation of the adjusting bolt 300.
