Abstract
A precise hole making combined tool for machining a balance-axle bracket comprises a tool body. A taper shank and a pop-rivet are arranged at the tail end of the tool body. The front end of the tool body stretches outwards to form a tool bar corresponding to the hole depth of a part to be machined, and the diameter of the tool bar is smaller than that of the tool body. Two indexable drilling blades are symmetrically installed at the front end of the tool bar, two indexable chamfering blades are symmetrically installed at the rear end of the tool bar, and spot facing blades are installed on the step surface of the rear end of the tool bar. Through batch production and machining verification, the performance and the quality of the balance-axle bracket are improved after the precise hole making combined tool is adopted. Tools for multiple processes are combined into one tool, hole making processes are reduced, clamping time and machining time of the balance-axle bracket are shortened, a large number of human resources and a large amount of equipment procurement money and consumption cost of various resources are reduced, production cost is reduced, production efficiency of the balance-axle bracket is improved, and the production environment is also greatly improved. The precise hole making combined tool is remarkable in benefits and has promotional value in the industry.
Description
Technical field
The utility model relates to the gang tool of machining, especially a kind of system essence hole gang tool of processing balance shaft support.
Background technology
Along with the Ou Man series vehicles such as tractor, flat car, dumper and medium-sized flat car dominate the market rapidly.Balance shaft support in Ou Man vehicle chassis part is of paramount importance parts, on balance shaft support, drilling needs three operations to complete, three operations are respectively milling 10-Φ 17 hole boss face, bore 10-Φ 17 holes, orifice chamfer, because these 10 hole precision prescribeies are high, boss face flatness requires high, and part is large, complex structure, and multiple clamping makes the precision of part not reach requirement, therefore, directly have influence on machining accuracy, processing cost and the production efficiency of balance shaft support.
Summary of the invention
The utility model proposes a kind of system essence hole gang tool of processing balance shaft support, make three orders be combined into an operation, the disposable processing that completes drilling, can improve the quality of products, and can improve productivity effect again.
For addressing the above problem, the technical solution of the utility model is: a kind of system essence hole gang tool of processing balance shaft support, comprise cutter hub, cutter hub tail end is taper shank and blind rivet, it is characterized in that: cutter hub front end is outward extended with the corresponding knife bar of hole depth with part to be processed, the diameter of knife bar is less than cutter hub, and the front end of knife bar is symmetrically installed with two indexable drill plates, and the rear end of knife bar is symmetrically installed with two indexable chamfering blades; Step surface place in knife bar rear end is provided with spot facing blade.
Beneficial effect: the utility model, through batch production processing checking, adopts after drilling gang tool, and properties of product and quality are improved; The knife combination that several operations are used is on a cutter, reduced the operation of drilling, thereby reduced clamping time and the process time of product, and reduced a large amount of human resources, equipment purchase and be equipped with fund and various resource consumption expense, also reduced production cost, the production efficiency that has improved balance shaft support, production environment is also very significantly improved; The utility model remarkable benefit, has the value of promoting in industry.
