Abstract
The invention provides a boring cutter rod, which comprises a cutter rod body and a cutter body, wherein a finely adjusting screw bolt is arranged on the cutter rod body; a threaded rack is fixedly connected onto the cutter body; finely adjusting screw threads and the threaded rack are connected through screw threads; and the side surface of the cutter body is provided with a wedge-shaped block. The boring cutter rod has the advantages that the radial feeding quantity of the cutter body is controlled through the finely adjusting effect of the finely adjusting screw rod; the cutter body clamping reliability is improved by utilizing the force increase clamping of the wedge-shaped block and the finely adjusting screw bolt; the clamping auxiliary time is reduced; the clamping of the boring cutter rod is convenient and fast; and the cutter setting precision and the cutter setting efficiency can be obviously improved.
Description
Technical field
The present invention relates to field of machining, particularly can carry out the boring cutter bar of finely tuning.
Background technology
On universal digital display boring machine when boring endoporus or size, trial cut adjusting method is usually adopted to determine tool sharpening size.Because Common boring cutter bar can not be finely tuned, tool setting precision is affected by human factors comparatively large, and the hole processed or axle edge easily produce and dig cutter phenomenon, affect crudy, even cause workpiece to scrap; Because cutter hub installation way adopts screw immediate roof push type broach body, although screw has self-locking action, owing to adopting dot point, poor stability, easily vibrates, and clamping is firm not, often occurs forging a knife, digging cutter phenomenon; In addition, tool setting extends and processes non-cutting time repeatedly, reduces production efficiency.
Summary of the invention
The object of the invention is to solve above technical problem, provide a kind of clamping convenient and swift, the boring cutter bar of tool setting precision and tool setting efficiency can be significantly improved.
For solving the problems of the technologies described above, present invention employs a kind of boring cutter bar, comprise knife bar body and cutter hub, described knife bar body is provided with trimming bolt, described cutter hub is fixedly connected with screw thread tooth bar, be threaded connection between described fine setting screw thread and screw thread tooth bar, described cutter hub side is provided with wedge.
The present invention is used for controlling the radial feeds of cutter hub by the fine setting of fine setting screw rod, utilizes the reinforcement of wedge and trimming bolt to clamp, improves cutter hub clamping reliability, decreases and clamps non-cutting time; By trying out on boring machine, proving that this cutter bar clamping is convenient and swift, tool setting precision and tool setting efficiency can be significantly improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that A-A of the present invention is to schematic diagram.
In figure: 1, knife bar body, 2, trimming bolt, 3, screw thread tooth bar, 4, cutter hub, 5, cutter head, 6, wedge.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1 and 2, be a kind of boring cutter bar, comprise knife bar body 1 and cutter hub 4, described knife bar body 1 is provided with trimming bolt 2, described cutter hub 4 is fixedly connected with screw thread tooth bar 3, is threaded connection between described fine setting screw thread 2 and screw thread tooth bar 3, described cutter hub 4 side is provided with wedge 6.
This boring cutter bar utilizes the wedge clamp system in horizontal and vertical direction to clamp cutter hub 4, because wedge and trimming bolt 2 all have locking and boosting function, knife bar body 1 can be made to clamp fast, reliably, required external force is less.Cutter hub 4 is equipped with the screw thread tooth bar be screwed, knife bar body 1 is equipped with trimming bolt 2.When needs regulate radial feeds, unclamp two wedges 6 be connected with shaft block ring, drive wedge 6 to unclamp cutter hub 4, then utilize trimming bolt 2 to regulate the radial feeds of cutter hub 4.For accurately controlling the amount of feeding, angle groove can be gone out at cutter hub 4 subscript.Meanwhile, in order to eliminate the gap of trimming bolt-screw thread tooth bar pair, avoiding finely tuning idle stroke, before unclamping wedge 6, trimming bolt 2 should be made to have certain pretightning force.In order to give full play to the usefulness of this boring cutter bar, cutter hub 4 is installed indexable insert carbide bit 5.
Claims (1)
1. a boring cutter bar, comprise knife bar body and cutter hub, it is characterized in that: described knife bar body is provided with trimming bolt, described cutter hub is fixedly connected with screw thread tooth bar, be threaded connection between described fine setting screw thread and screw thread tooth bar, described cutter hub side is provided with wedge.
