Description

Technical Field

[0001] The utility model relates to the field of vertical lathes, and particularly relates to an auxiliary support structure for columnar workpieces of a vertical lathe. Background Technique

[0002] A vertical lathe is a lathe used for machining large and heavy workpieces and workpieces that are not easy to be clamped on a horizontal lathe. A vertical lathe, abbreviated as a "vertical lathe", has a spindle axis perpendicular to the horizontal plane, and the workpiece is installed on a horizontal rotary table.

[0003] In the prior art, the positioning of workpieces on traditional lathes usually uses a hydraulic tappet mechanism in combination with a clamping plate to clamp and position both ends of the workpiece in the horizontal direction. This positioning method is simple to operate and stable in positioning.

[0004] However, when using a vertical lathe to position a columnar workpiece, the axis of the workpiece is perpendicular to the worktable. When using the workpiece positioning method of a traditional lathe to clamp the workpiece, there will be a situation of insufficient lateral support, and the workpiece is prone to tilt during the machining process, resulting in low machining accuracy. Content of the Utility Model

[0005] The purpose of the utility model is to provide an auxiliary support structure for columnar workpieces of a vertical lathe to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an auxiliary support structure for columnar workpieces of a vertical lathe, including: a support frame and a worktable fixed with the support frame. A workpiece is arranged at the top of the worktable. A support rod is movably inserted on the surface of the support frame. A collar is sleeved on the surface of the workpiece. A support groove is opened on the surface of the collar. One end of the support rod away from the support frame is movably inserted into the support groove. The collar is provided with a variety of different specifications.

[0007] Preferably, the support frame has an "L"-shaped rod structure. There are four groups of support frames, which are circumferentially distributed on the surface of the worktable. A support rod installation groove is opened on the surface of the cross bar of the support frame. One end of the support rod away from the collar is movably inserted into the support rod installation groove.

[0008] Preferably, the support rod has a circular rod structure. A spring is fixed at one end of the support rod extending into the support rod installation groove, and the other end of the spring is fixed on the inner wall of the groove body of the support rod installation groove.

[0009] Preferably, a screw hole is opened on the surface of the support frame, and the screw hole communicates with the support rod installation groove.

[0010] Preferably, a screw rod is rotationally inserted into the screw hole. The screw rod is in threaded engagement with the screw hole. One end of the screw rod extending into the support rod installation groove abuts against the surface of the support rod, and the other end of the screw rod extends out of the screw hole.

[0011] Preferably, a lever is fixed on the rod body of the end of the screw rod extending out of the screw hole.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The auxiliary support structure for columnar workpieces used in a vertical lathe proposed by the present utility model has various specifications for the ring sleeves. According to the diameter of the workpiece, the corresponding specification of the ring sleeve is rotated, and the ring sleeve is sleeved on the surface of the workpiece. The inner wall of the ring sleeve is the same as the diameter of the workpiece. Then, the support rods on the surfaces of each group of support frames are retracted into the support rod installation grooves. Then, the workpiece sleeved with the ring sleeve is placed in the middle of the workbench. Then, the support rods are inserted into the forming grooves, and the screw rod abuts against the surface of the end of the support rod extending into the support rod installation groove. Then, when the workpiece has a tendency to tip over, the horizontal component force generated by the gravity of the workpiece is transmitted to the ring sleeve and then to the support rod, and then from the support rod to the screw rod. Finally, under the threaded connection of the screw rod and the screw hole, it is transmitted to the support frame. Then, the reaction force of the support frame is transmitted to the workpiece through the opposite path, providing lateral auxiliary support for the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0019] Embodiment 1

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a columnar workpiece auxiliary support structure for a vertical lathe, including: a support frame 2 and a workbench 1 fixed with the support frame 2. A workpiece 10 is arranged at the top of the workbench 1. A support rod 3 is movably inserted on the surface of the support frame 2. A collar 4 is sleeved on the surface of the workpiece 10. A forming groove 5 is opened on the surface of the collar 4. One end of the support rod 3 away from the support frame 2 is movably inserted into the forming groove 5. The collar 4 is provided with a variety of different specifications.

[0021] During actual use, the collar 4 is provided with a variety of specifications. According to the diameter of the workpiece 10, the corresponding specification of the collar 4 is rotated, and the collar 4 is sleeved on the surface of the workpiece 10. The inner wall of the collar 4 has the same diameter as the workpiece 10. Then, the support rods 3 on the surfaces of the respective support frames 2 are retracted into the support rod installation grooves 6. Then, the workpiece 10 sleeved with the collar 4 is placed in the middle of the workbench 1. Then, the support rods 3 are inserted into the forming grooves 5, and the screw 9 is abutted against the surface of one end of the support rod 3 extending into the support rod installation groove 6. Then, when the workpiece 10 has a tendency to tip over, the horizontal component force generated by the gravity of the workpiece 10 is transmitted to the collar 4 and then to the support rod 3, and then from the support rod 3 to the screw 9. Finally, under the threaded connection of the screw 9 and the threaded hole 8, it is transmitted to the support frame 2. Then, the reaction force of the support frame 2 is transmitted to the workpiece 10 through the opposite path, providing lateral auxiliary support for the workpiece 10.

[0022] Embodiment Two

[0023] On the basis of Embodiment One, in order to realize the pre-positioning of the collar 4, the support frame 2 is in an "L"-shaped rod structure. There are four groups of support frames 2, and the four groups of support frames 2 are circumferentially distributed on the surface of the workbench 1. A support rod installation groove 6 is opened on the cross bar surface of the support frame 2. One end of the support rod 3 away from the collar 4 is movably inserted into the support rod installation groove 6. The support rod 3 is in a circular rod structure. A spring 7 is fixed at one end of the support rod 3 extending into the support rod installation groove 6, and the other end of the spring 7 is fixed on the inner wall of the groove body of the support rod installation groove 6.

[0024] Before placing the workpiece 10 sleeved with the collar 4 on the workbench 1, first retract the support rod 3 completely into the support rod installation groove 6, which compresses the spring 7. Then, place the workpiece 10 sleeved with the collar 4 on the workbench 1, and turn the position of the collar 4 to align the forming groove 5 with the support rod installation groove 6. Then, release the support rod 3, and the spring 7 will push one end of the support rod 3 into the forming groove 5 under its own elastic force, so as to pre-position the collar 4.

[0025] Embodiment Three

[0026] On the basis of the second embodiment, in order to fix the ring sleeve 4, a screw hole 8 is opened on the surface of the support frame 2, and the screw hole 8 is connected with the support rod mounting groove 6. A screw rod 9 is rotatably inserted in the screw hole 8, and the screw rod 9 is matched with the thread of the screw hole 8. One end of the screw rod 9 extends into the support rod mounting groove 6 and abuts on the surface of the support rod 3, and the other end of the screw rod 9 extends out from the screw hole 8. A lever 11 is fixed to the rod body at one end of the screw rod 9 extending out of the screw hole 8.

[0027] Before the support rod 3 is fully retracted into the support rod mounting groove 6, the screw rod 9 is first rotated by toggling the toggle lever 11 to make the screw rod 9 withdraw from the support rod mounting groove 6, providing space for the support rod 3 to be fully retracted into the support rod mounting groove 6. After one end of the support rod 3 is pushed into the formed groove 5 by the spring 7, the screw rod 9 is rotated in the opposite direction to make the screw rod 9 re-extend into the support rod mounting groove 6 and rest against the surface of the support rod 3, so that one end of the support rod 3 is fixed in the formed groove 5 under the action of the screw hole 8 and the thread of the screw rod 9.

[0028] When the workpiece 10 is in a state of being tilted, the workpiece 10 is prevented from being tilted by the action of the screw 9 and the workpiece 10 being rotated. Before placing 10 on the workbench 1, the support rod 3 is first completely retracted into the support rod mounting groove 6, which compresses the spring 7. Then the workpiece 10 with the ring sleeve 4 is placed on the workbench 1, and the position of the ring sleeve 4 is turned to align the finished groove 5 with the support rod mounting groove 6. Then, the support rod 3 is loosened, and the spring 7 pushes one end of the support rod 3 into the finished groove 5 under the action of its own elasticity, so that the ring sleeve 4 can be pre-positioned; before the support rod 3 is completely retracted into the support rod mounting groove 6, the screw rod 9 is first rotated by toggling the toggle lever 11 to make the screw rod 9 withdraw from the support rod mounting groove 6 to provide space for the support rod 3 to be completely retracted into the support rod mounting groove 6. After one end of the support rod 3 is pushed into the finished groove 5 by the spring 7, the screw rod 9 is rotated in the opposite direction to make the screw rod 9 re-extend into the support rod mounting groove 6 and abut against the surface of the support rod 3, so that one end of the support rod 3 is fixed in the finished groove 5 under the action of the screw hole 8 and the thread of the screw rod 9.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
