[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] This application addresses the technical problems in the prior art of inconvenient adjustment of the tailstock or worktable, difficult operation, low processing efficiency, and inaccurate angle of the tapered surface; it provides a structural component for quickly adjusting the eccentricity, which can quickly adjust the eccentricity of the tailstock center, thereby meeting the processing requirements of the tapered surface. The device is easy to use and simple to operate, and the taper angle can be accurately adjusted through eccentricity calculation and precise adjustment.

[0019] Figure 1 Shows the overall structural diagram of the fast-adjustable top device; Figure 2 FIG. 1 shows a schematic diagram of a structure formed by combining rib edge 120 and rib edge 2 130; and FIG. Figure 1In the diagram, the direction indicated by the arrow represents the direction of the adjustment end, and the opposite direction represents the direction of the assembly end. Figure 1 and Figure 2In the embodiment, the fast adjustable top device includes a tail 100 and a head 200 installed at the adjustment end of the tail 100, the tail 100 includes a bottom plate 110, and the adjustment end of the bottom plate 110 has two spaced ribs 120 and two oppositely arranged ribs 2 130, the two ribs 120 and the two ribs 2 130 are alternately connected end to end to form a cavity 140 for accommodating the head 200, the two ribs 120 abut on both sides of the head 200 and limit the movement trajectory of the head 200, and there is an adjustable spacing between the two ribs 2 130 and the head 200, and each rib 2 130 is rotatably connected with a bolt 150, and the two bolts 150 are inserted into the cavity 140 and respectively abut the head 2 00 opposite sides; in actual use, the head 200 is installed in the cavity 140 as a whole. At this time, the two ribs 120 abut against the head 200 and limit its movement trajectory, that is, the head 200 will move back and forth between the two ribs 130 according to the trajectory of the rib 120 to achieve adjustment. After the adjustment is completed, the two bolts 150 are rotated so that the insertion end of the bolt 150 abuts against the head 200, thereby achieving relative fixation of the head 200 and the tail 100; it should be noted that the rib 2 130 and the bolt 150 are threaded. When the rib 2 130 is locked and the driving bolt 150 is driven to rotate relative to the rib 2 130, the bolt 150 can be screwed into or out of the cavity 140 to To achieve the change of the relative position with respect to the head 200; the bottom plate 110 is provided with a screw hole 111 along the thickness direction, and the head 200 includes a slide plate 210 slidably connected to the cavity 140, and a slideway 211 corresponding to the screw hole 111 is provided along the thickness direction of the slide plate 210, and a bolt 212 is inserted into the slideway 211, and the screw portion of the bolt 212 passes through the slideway 211 and is screwed into the screw hole 111, and the screw head of the bolt 212 presses the adjustment end of the slide plate 210; after the slide plate 210 is pressed and restricted by the two bolts 150, the screw portion of the bolt 212 passes through the slideway 211 and is screwed into the screw hole 111 until the screw head of the bolt 212 presses the end face of the slide plate 210, and the screw 212 and the bottom plate 110 are pressed and restricted. To restrict the clamped slide 210, within the same plane, the cooperation of two bolts 150, bolt 212, and the base plate 110 can achieve restriction of the slide 210 in four directions, thereby ensuring the fixing effect of the slide 210 after adjustment. The adjustment end of the slide 210 has a protruding pointed cone 220, and the assembly end of the base plate 110 has a tail cone 160. In the installed state, the pointed cone 220 and the tail cone 160 are coaxial. The tail cone 160 can cooperate with the tailstock sleeve of the lathe to install the entire device on the lathe. After the pointed cone 220 and the tail cone 160 are coaxial, the processing effect of the pointed cone 220 can be guaranteed. The end surface of the adjustment end of the rib 120 is provided with a scale line 121 corresponding to the pointed cone 220.The scale lines 121 provide a reference for the relative position of the head 200 when adjusting it, facilitating real-time observation. A dial indicator (not shown) is mounted on one side of the second rib 130. The output end of the dial indicator is inserted between the second rib 130 and the slide 210 and contacts the slide 210. The dial indicator allows for more accurate determination of the overall position of the head 200 and precise adjustment of the eccentricity.
