Abstract
The utility mode provides a deep hole boring device capable of ensuring the requirement on geometric tolerance of parts, comprising a cutter and a guiding device. The cutter comprises a cutter handle, a lengthened connecting rod, a coarse boring head and a coarse cutter holder in sequence, wherein the guiding device is positioned at one end close to the coarse boring head, and sheathed on the lengthened connecting rod. In the deep hole boring device, as the cutter is formed by combining standard cutter assemblies, so that the deep hole boring device has the advantages of standardization, universality and combination; and as the guiding device is additionally arranged, the problem of cutter vibration in the inner hole in the deep hole processing can be solved, and the relevant requirement on the geometric tolerance is met.
Description
Technical field
The utility model relates to a kind of boring equipment, especially a kind of deep hole boring equipment.
Background technology
In the deep hole boring field, for example: during the high pound level of processing ball valve body, it is 903mm that inner cavity of component needs working depth, and radius is the semi arch of 117mm, existing process equipment is that horizontal boring machine (TPX6111) utilizes main shaft (W shaft diameter 110mm) to put in body cavity, shortens tool length.Though energy the said equipment can reach the cutting depth of drawing requirement, can't satisfy the Geometrical Tolerance Principle of part, and boring efficient is low, the cost height.
The utility model content
The utility model provides a kind of deep hole boring equipment that can guarantee each Geometrical Tolerance Principle of part in order to overcome the deficiency of above-mentioned existing boring equipment.
Realize the deep hole boring equipment of the utility model purpose, comprise cutter and guider, described cutter comprises handle of a knife successively, the lengthening extension bar, and heavy boring head and heavy boring cutter holder, described guider are positioned near the first end of described heavy boring, are enclosed within on the described lengthening extension bar.
Described guider comprises described guider is connected transition disc on the platen, be fixed on the positioning disk on the described transition disc, be fixed on locating support and the fairlead that is positioned at described locating support top on the described positioning disk, described lengthening extension bar passes described fairlead.Guider can prevent cutter circular runout when cutting, improves machining accuracy.
Described fairlead is provided with the holding screw that is used for aligned cutting tool.Holding screw is used for fixing the position of fairlead on the lengthening extension bar.
Described holding screw is more than two, is positioned at a side of described lengthening extension bar.
The cross section of described locating support is L-shaped, comprises a horizontal plane and a vertical plane.
On the described locating support, the below that is positioned at described fairlead is provided with the reinforcement that connects described horizontal plane and vertical plane.
The cross section of described reinforcement is triangular in shape.
The joint face of described locating support and positioning disk is provided with the location flat key, is used for accurately locating the position of described locating support on positioning disk.
Therefore deep hole boring equipment of the present utility model have standardization, versatility, the characteristics of property capable of being combined because its cutter is the cutter accessory of employing standard combines; Owing to increased guider, the endoporus in the deep hole machining shake cutter problem and relevant Geometrical Tolerance Principle have been solved.Deep hole boring equipment of the present utility model can be finished the processing of high accuracy deep hole, has improved yield rate and working (machining) efficiency greatly, has reduced cost.

The specific embodiment
Deep hole boring apparatus embodiments of the present utility model is as follows:
As shown in Figure 1, the deep hole boring equipment of present embodiment comprises cutter and guider 4, and cutter comprises handle of a knife 1 successively, lengthening extension bar 2, and heavy boring head 5 and heavy boring cutter holder 6, guider 4 are positioned at the end near heavy boring head 5, are enclosed within on the lengthening extension bar 2.
Deep hole boring equipment of the present utility model is because its cutter is the cutter accessory of employing standard combines, therefore has standardization, versatility, the advantage of property capable of being combined, and deep hole boring equipment of the present utility model has been owing to increased guider, solved the endoporus in the deep hole machining shake cutter problem and relevant Geometrical Tolerance Principle, therefore can finish the processing of high accuracy deep hole, improve yield rate and working (machining) efficiency greatly, reduced cost.
Shown in Fig. 1～4, guider 4 comprises guider 4 is connected transition disc 11 on the platen, be fixed on positioning disk 12 on the transition disc 11 by screw 17, be fixed on the locating support 14 on the positioning disk 12 and be positioned at the fairlead 15 on locating support 14 tops by screw 13, lengthening extension bar 2 passes fairlead 15.
Fairlead 15 is provided with the holding screw 3 that is used for aligned cutting tool, and holding screw 3 is more than two, is positioned at a side of lengthening extension bar 2.The longitudinal section of locating support 14 is L-shaped, comprises a horizontal plane and a vertical plane.On locating support 14, the below that is positioned at fairlead 15 is provided with the horizontal plane of connection locating support and the reinforcement 18 of vertical plane, the longitudinal section of reinforcement 18 is triangular in shape, the joint face of locating support 14 and positioning disk 12 is provided with location flat key 16, is used for accurately locating the position of locating support 14 on positioning disk 12.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
