Description

Technical Field

[0001] The utility model relates to the technical field of reverse pull tool bars, in particular to a combined reverse pull tool bar. Background Art

[0002] A reverse-pull tool bar is a specially designed tool bar, which is mainly used in situations where cutting is required from the reverse side during processing. The design of this tool bar allows the tool to start cutting from the non-processing surface of the workpiece, which is very useful when the processing space is limited or a special processing path is required. Reverse-pull tool bars are usually used in machining centers, CNC lathes or other automated machine tools to achieve high-precision and high-efficiency processing. At present, most tool bars are integrated and fixedly connected. When the cutting part is worn or damaged, the entire tool needs to be replaced, which increases the replacement cost. In addition, the tool bar height is fixed and cannot be adjusted, which reduces the overall practicality. Utility Model Content

Finally, the fixing ring 22 is sleeved on the connecting rod 21, and the two pairs of bolts 15 fixed on the fixing ring 22 will be fixed to the connecting ring 12. The whole is a modular design. When the cutting part is worn or damaged, only the cutting part needs to be replaced instead of the entire tool, thereby reducing the replacement cost.

[0024] Two pairs of slots 10 are provided on the upper surface of the base 3, and the two pairs of slots 10 are movably connected with the two pairs of blocks 13 respectively. The surfaces of the two pairs of blocks 13 are threadedly sleeved with screws 14, and the two pairs of screws 14 are threadedly sleeved with the two pairs of slots 10 respectively.

[0026] Working principle:

[0027] When the reverse broaching rod is assembled and used, firstly, the fixing rod 1 is clamped on the base 3. The fixing rod 1 is clamped by two pairs of clamping blocks 13 fixed thereon and two pairs of clamping grooves 10 opened on the surface of the base 3, and then threadedly fixed by two pairs of screws 14 to ensure the stability of the connection between the two. At this time, the connecting rod 21 is connected to the fixing rod 1 through the fixing seat 18 fixed thereunder. When the connecting rod 21 is clamped on the fixing rod 1, the two pairs of limit blocks 16 are subjected to pressure and move toward the opposite surface, compressing the two pairs of springs 17. The upper and lower surfaces of the two pairs of limit blocks 16 are inclined. When the connecting rod 21 is clamped to the top, the two pairs of limit blocks 16 will be clamped with the two pairs of clamping grooves 11 opened on the inner wall of the fixing rod 1, and the two are in a clamped state. Finally, the fixing ring 22 is sleeved on the connecting rod 21, and the two pairs of bolts 15 fixed on the fixing ring 22 are fixed.

When the cutting part is worn or damaged, only the cutting part needs to be replaced instead of the entire tool, thereby reducing the replacement cost. In addition, the tool head can be replaced according to different processing requirements, which improves the overall adaptability. When the tool rod is in use, the threaded ring 7 is rotated downward to drive the threaded ring 2 8 fixed with it to rotate together. Both surfaces are fixed with equidistant rubber strips to increase friction and facilitate rotation. The threaded ring 7 will be separated from the fixation with the connecting rod 5 during the downward rotation process, and the limit is opened. The connecting rod 5 can move up and down. After moving and adjusting to the required height, the threaded ring 7 is rotated upward to limit and fix it. The overall operation is simple and easy to use. The height-adjustable design improves the flexibility of the tool rod during use and improves the overall practicality.
