Abstract
The utility model relates to a central adjusting support mechanism, which comprises a casing body, a support bar, an endless screw and a worm gear, wherein the worm gear is coaxially pivoted with the support bar, and the support bar, the endless screw and the worm gear are arranged in the casing body, and the worm gear is meshed with the endless screw. The central adjusting support mechanism can be mounted on the boring shaft of a boring machine, the processing precision of the boring machine is high, and the product quality can not be influenced.
Description
Technical field
The utility model relates to a kind of center adjustment supporting mechanism.
Background technology
Existing boring machine generally comprises drive system, supporting device and the tool feeding mechanism of boring axle and boring axle, can carry out boring to workpiece; When this kind boring machine was at large-scale workpiece then, because it needs the length of boring long especially, in the process of boring, swing can appear in this boring axle, thereby caused workpiece processing inaccurate, and machining accuracy is little, influences the quality of product.In order to overcome this shortcoming, when the darker hole of boring, need be boring bar processing very thick, it is difficult that the transportation of waste material, and very thick boring bar like this and installing is all compared.
Summary of the invention
The utility model purpose is to provide a kind of center adjustment supporting mechanism, and it can be mounted on the boring axle of boring machine, eliminates the shortcoming that boring machine is swung when the boring deep hole, makes the machining accuracy height of boring machine, can not influence product quality.
To achieve these goals, the utility model center adjustment supporting mechanism, its structure comprises housing, support bar, worm screw, worm gear; Described worm gear and the coaxial pivot joint of support bar, support bar, worm screw and worm gear are positioned at housing, worm gear and worm engaging; This center adjustment supporting mechanism can be mounted on the boring axle of boring machine, makes the machining accuracy height of boring machine, can not influence product quality.
As improvement, described support bar can be two or more, and the support bar circle distribution all coaxially on each support bar is articulated with a worm gear on housing, and each worm gear all has a worm screw to be engaged with; This support bar can be located the boring axle, and assurance boring axle can not swung, and makes the machining accuracy height.
As further improvement, be fixed with a rotating rod on the described worm screw, can be used to regulate support bar turnover housing, guarantee that support bar can contact with work piece.
As further improving again, end cap is installed being positioned on the housing of support bar, support bar passes described end cap, and end cap is fixed on the housing by screw, prevents that dust from entering the worm and gear engagement place.
Compared with prior art, the utility model center adjustment supporting mechanism, it can be mounted on the boring axle of boring machine, can guarantee that the boring axle can not swing, and makes the machining accuracy height of boring machine, can not influence product quality.
Description of drawings
Fig. 1 is the front view of the utility model center adjustment supporting mechanism;
Fig. 2 is the side view of the utility model center adjustment supporting mechanism;
The schematic diagram that Fig. 3 processes for the utility model center adjustment supporting mechanism.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Please refer to illustrated in figures 1 and 2, the utility model center adjustment supporting mechanism, its structure comprises housing 3, support bar 1, worm screw 2, worm gear 4; Described worm gear 4 and support bar 1 coaxial pivot joint, support bar 1, worm screw 2 and worm gear 4 are positioned at housing 3, worm gear 4 and worm screw 2 engagements.Wherein, described support bar 1 can be two or more, is four support bars 1 in the present embodiment, and described support bar 1 circle distribution all coaxially on each support bar 3 is fixed with a worm gear 4 on housing 3, and each worm gear 4 all has a worm screw 2 to be engaged with; This support bar 1 can be located boring bar 6, and assurance boring bar 6 can not swung, and makes the machining accuracy height.In addition, be fixed with a rotating rod 5 on the described worm screw 2, rotating rod 5 can be used to regulate support bar 1, can guarantee that in the process of processing the boring axle can not swing.
Rotate rotating rod 5, rotating rod 5 drives worm screw 2 and rotates, worm screw 2 drives worm gear 4 rotations with its engagement, worm gear 4 drives and the support bar 1 of its pivot joint can pass in and out housing 3, described support bar 1 can support the inwall of workpiece, and this center adjustment supporting mechanism can be mounted on the boring axle of boring machine, is adding man-hour, guarantee the machining accuracy height of boring axle, can not influence product quality.
Compared with prior art, the utility model centering control support mechanism is because it can be installed To the boring axle of boring machine, can guarantee that the boring axle can not swing, make the machining accuracy height of boring machine, can not Affect product quality.
