Background technology
Boring machine is the capital equipment of large-size box part processing, mainly is used for machining screw, cylindrical and end face etc.
At present, for the secret box body hole of processing single hole, like the main spindle box body opening on the Digit Control Machine Tool, high-performance motor casing body opening etc., requirement on machining accuracy is higher; Existing boring machine is fixed on part in the clamping device of boring machine in processing parts, and an end of processing parts then is in the time of the needs processing parts other end; Need part be taken off, the adjustment position sticks into again; Process again, yet, in the process of rechuck; Because machinery itself or artificial problem, always keep away and error unavoidably occurs, thereby have influence on the machining accuracy of part.
Therefore, need a kind of horizontal-type biaxial numerical control borer especially, to solve the problem that exists in the prior art.
The utility model content
The purpose of the utility model is to provide a kind of horizontal-type biaxial numerical control borer, and to the defective that prior art exists, a clamping just can be accomplished the processing of two end faces, and the degree of accuracy is high, and is simple in structure, and is very practical.
To achieve these goals, the technical scheme of the utility model is following:
A kind of horizontal-type biaxial numerical control borer; Comprise the boring machine body; Said boring machine body comprises part clamping device and truning fixture, and said truning fixture comprises knife rest that is used for fixing cutter and the transmission device that is used to change the knife rest position, and it is characterized in that: said part clamping device is arranged on the middle part of boring machine body; The quantity of said truning fixture is two, the corresponding respectively two ends that are arranged on the part clamping device.
In the utility model, the said knife rest that is used for fixing cutter comprises boring head motor that is arranged on the boring machine topmost and the belt pulley that is connected with the boring head motor.
In the utility model, the bottom of said boring head motor is provided with electric machine support, and boring head is arranged at the bottom of said electric machine support, and an end of said boring head connects cutter, and the other end connects belt pulley,
In the utility model, the said belt pulley that is connected with motor is connected through belt with the belt pulley that is connected with boring head.
In the utility model, said transmission device comprises motor and the screw mandrel and sliding spirit that are used to control the knife rest direction of motion.
In the utility model, said screw mandrel is connected through shaft coupling with motor, and the bottom of said motor is provided with electric machine support, and the support cushion block is arranged at said electric machine support bottom.
A kind of horizontal digital-control boring machine of the utility model is compared with existing product, at the two ends of part clamping device system of processing is set respectively; Make the part by one-step clamping just can realize the processing at two ends, simple in structure, avoided the error of multiple clamping; Machining accuracy is high, has realized the purpose of the utility model.
The characteristics of the utility model can consult this case graphic and below better embodiment detailed description and obtain to be well understood to.
Description of drawings
Fig. 1 is the structural representation of a kind of horizontal-type biaxial numerically controlled lathe of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, further set forth the utility model below in conjunction with specific embodiment.
A kind of horizontal-type biaxial numerical control borer; Comprise boring machine body 100; Boring machine body 100 comprises clamping device 200 that is used for fixing part and the truning fixture 300 that part is processed, and truning fixture 300 comprises knife rest 310 that is used for fixing cutter and the transmission device 320 that is used to change the knife rest position.
Part clamping device 200 is arranged on the middle part of boring machine body 100, and the quantity of truning fixture 300 is two, the corresponding respectively two ends that are arranged on part clamping device 200.
The knife rest 310 that is used for fixing cutter comprises boring head motor 311 that is arranged on the boring machine topmost and the belt pulley 312 that is connected with boring head motor 311; In the bottom of boring head motor 311 electric machine support 400 is set; Boring head 500 is arranged at the bottom of said electric machine support 400; One end of said boring head 500 connects cutter 510, and the other end connects belt pulley 520, and the belt pulley 312 that is connected with motor is connected through belt 600 with the belt pulley that is connected with boring head 520.
Transmission device 320 comprises motor 321 and the screw mandrel 322 and sliding spirit 323 that are used to control the knife rest direction of motion.Screw mandrel 322 is connected through shaft coupling 800 with motor 321, and the bottom of said motor 321 is provided with electric machine support 700, and support cushion block 710 is arranged at said electric machine support 700 bottoms.
When in use, part is fixed on the clamping device 200 of part, if the two ends of part all need processing; Just can work out out different programs according to the position of part and cutter and process, in processing, cutter is fixed on the knife rest; Boring head motor 311 rotates; Drive cutter 510 quick rotation on the boring head 500, rotate, drive screw mandrel and rotate and just can realize that cutter does the feed motion of Y direction through motor 321; Do the feed motion of directions X again through sliding spirit 323, just processing parts easily.
A kind of horizontal-type biaxial numerical control borer of the utility model compared with prior art, is provided with truning fixture at the two ends of the clamping device of part; When making processing, a clamping just can be accomplished the processing at part two ends, and is simple in structure; Practicality is put just, realizes the purpose of the utility model.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the specification of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
