Description

Technical Field

[0001] The utility model relates to the technical field of bar processing, in particular to a positioning component for bar fixture processing. Background Technique

[0002] When positioning and processing bars, it is often necessary to adjust the angle and position of the bars to process different places. However, for existing positioning equipment, when the bars need to be adjusted, repositioning is required, and errors are likely to occur after repositioning, affecting the final processing effect. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a positioning component for bar fixture processing, which solves the above-mentioned problems.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A positioning component for bar fixture processing includes a fixed seat and three first driving cylinders annularly and integrally fixed in the inner cavity of the fixed seat. The piston rod ends of the three first driving cylinders are fixedly connected with a first wheel frame. A first guiding wheel is rotatably connected in the inner cavity of the first wheel frame. Both sides of the first wheel frame are fixedly connected with second driving cylinders. The piston rod ends of the two second driving cylinders are fixedly connected with second wheel frames. A second guiding wheel is rotatably connected in the inner cavity of each of the two second wheel frames. The rotation direction of the first guiding wheel is towards the axial rotation direction of the bar, and the rotation direction of the second guiding wheel is towards the transverse movement direction of the bar. A notch for the bar to enter is opened on one side of the fixed seat;

[0005] It further includes a supporting mechanism arranged on the side of the fixed seat for supporting the bar. When in use, the bar is placed into the fixed seat through the notch. Then, at this time, the double-rod driving cylinder is used to drive the moving frame to move towards the bar, and the fixed clamps at both ends of the conduction rod respectively abut against the sides of the bar. Through the force conduction of the rotating frame, the two fixed clamps uniformly apply force to the bar. Through the arrangement of the upper and lower four fixed clamps, the bar can be effectively fixed and positioned. Then, the first driving cylinder drives the first wheel frame to extend, driving the first guiding wheel to abut against the surface of the bar. At this time, the bar is positioned. Then, when the bar needs to be axially rotated for processing, the bar can drive the first guiding wheel to rotate, and even when rotating, the fixing effect on the bar can be ensured. When the bar needs to be moved left and right, the second driving cylinder is used to drive the second wheel frame to extend, driving the second guiding wheel to abut against the surface of the bar. Then, the first driving cylinder drives the first guiding wheel to retract a little to reduce the extrusion force on the bar. Then, under the guiding and limiting of the second guiding wheel, the bar can ensure a good positioning effect when moving left and right without re-calibrating and positioning, and the processing accuracy is higher.

[0006] As a further solution of the present utility model: the two second guide wheels are respectively arranged on both sides of the first guide wheel, and are supported at two points on both sides, so the force is more stable.

[0007] As a further solution of the present utility model: the supporting mechanism includes two moving frames arranged on the side of the fixed seat and respectively driven by double-rod cylinders. One side of the moving frame facing the bar is rotatably connected with a conduction rod through a rotating frame. Both ends of the conduction rod are respectively fixedly connected with fixing clips facing the bar. When in use, the double-rod driving cylinder drives the moving frame to move towards the bar, and then the fixing clips at both ends of the conduction rod respectively abut against the side of the bar. The force is transmitted through the rotating frame, so that the two fixing clips apply force to the bar evenly. The bar can be effectively fixed by arranging four fixing clips up and down.

[0008] As a further solution of the present utility model: the side of the fixing clip facing the bar is provided with an adaptation groove, and various diameters of bars can be clamped through the setting of the adaptation groove.

[0009] The present utility model has the following beneficial effects compared with the prior art:

[0010] 1. In the present utility model, when axial rotation processing of the bar is required, the bar can drive the first guide wheel to rotate, and the fixing effect on the bar can be ensured even during rotation. When the bar needs to be moved left and right, the second driving cylinder is used to drive the second wheel frame to extend, driving the second guide wheel to abut against the surface of the bar. Then the first driving cylinder drives the first guide wheel to retract a little to reduce the extrusion force on the bar. Then, under the guiding and limiting of the second guide wheel, the bar can ensure a good positioning effect when moving left and right, without re-calibrating the position, and the processing accuracy is higher.

[0011] 2. In the present utility model, the double-rod driving cylinder drives the moving frame to move towards the bar, and then the fixing clips at both ends of the conduction rod respectively abut against the side of the bar. The force is transmitted through the rotating frame, so that the two fixing clips apply force to the bar evenly. The bar can be effectively fixed by arranging four fixing clips up and down.

One side of the moving frame 8 facing the bar is rotatably connected with a conduction rod 10 through a rotating frame 9. Both ends of the conduction rod 10 are respectively fixedly connected with fixed clamps 11 facing the bar. When in use, the double-rod driving cylinder drives the moving frame 8 to move towards the bar, and the fixed clamps 11 at both ends of the conduction rod 10 respectively abut against the side of the bar. Through the force conduction of the rotating frame 9, the two fixed clamps 11 uniformly apply force to the bar.
