Description
Technical field
The utility model belongs to grinding; Polishing technology field, especially relates to a kind of improvement of screw rod polishing mechanism structure.
Background technology
Along with the fast development of China's processing manufacturing industry, the demand of accurate screw rod is also day by day obvious.But the processing technology of accurate screw rod still backwardness at home, and external advanced technologies method is because the reason such as with high costs is difficult to introduce.The improvement of accurate screw rod process equipment has been the task of top priority with promoting.
Summary of the invention
The utility model is exactly for the problems referred to above, provides the polishing mechanism of the screw rod that a kind of efficiency is high, precision is high.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, a kind of polishing mechanism of screw rod, it is characterized in that: comprise head of a bed chuck, to be provided with tail platform accordingly top with head of a bed chuck, the described top tip of tail platform is towards head of a bed chuck, and the top rear end of tail platform is connected with pushing structure; Roughing rubbing head, semifinishing rubbing head, fine finishining rubbing head and superfinish polish head is placed with successively above head of a bed chuck and the top middle part of tail platform; Described roughing rubbing head, semifinishing rubbing head, fine finishining rubbing head and superfinish polish head are connected to translation device.
Described roughing rubbing head, semifinishing rubbing head, fine finishining rubbing head are identical with the structure of superfinish polish head, and difference is that the amount of feeding in cutting direction increases successively.
As a kind of preferred version, described pushing structure is the screw structure of driven by servomotor.
As a kind of preferred version, described pushing structure is oil cylinder.
As another preferred version, the rack-and-pinion that described translation device is servomotor and cooperatively interacts, gear is arranged on the motor shaft of servomotor, and described roughing rubbing head, semifinishing rubbing head, fine finishining rubbing head and superfinish polish head are connected to tooth bar one end of different translation device.
The beneficial effects of the utility model.
The utility model applies the rubbing head of many group servo-drive to complete the high accuracy of screw rod, can reach essence and throw effect, while improving screw rod crudy significantly, substantially increase production efficiency after the processing of screw rod stock removal polishing.The utility model effectively solves and needs repeatedly to change the overlength screw rod caused in abrasive band in the low process of screw rod polishing production process medium sand tape lifetime in the past and add ropy problem in man-hour, effectively improve the processing life-span in abrasive band simultaneously, save abrasive band replacing construction, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1 be screw workpiece, 2 be superfinish polish head, 3 be fine finishining rubbing head, 4 be semifinishing rubbing head, 5 be roughing rubbing head, 6 for tail platform is top, 7 for head of a bed chuck.
Detailed description of the invention
As shown in Figure 1, a kind of polishing mechanism of screw rod, is characterized in that: comprise head of a bed chuck 7, is provided with tail platform top 6 accordingly with head of a bed chuck 7, and top 6 tips of described tail platform are towards head of a bed chuck 7, and top 6 rear ends of tail platform are connected with pushing structure; Roughing rubbing head 5, semifinishing rubbing head 4, fine finishining rubbing head 3 and superfinish polish head 2 is placed with successively above in the middle part of head of a bed chuck 7 with tail platform top 6; Described roughing rubbing head 5, semifinishing rubbing head 4, fine finishining rubbing head 3 and superfinish polish head 2 are connected to translation device.
Described roughing rubbing head 5, semifinishing rubbing head 4, fine finishining rubbing head 3 are identical with the structure of superfinish polish head 2, and difference is that the amount of feeding in cutting direction increases successively.
Described pushing structure is the screw structure of driven by servomotor.
Described pushing structure is oil cylinder.
The rack-and-pinion that described translation device is servomotor and cooperatively interacts, gear is arranged on the motor shaft of servomotor, and described roughing rubbing head, semifinishing rubbing head, fine finishining rubbing head and superfinish polish head are connected to tooth bar one end of different translation device.
Below in conjunction with accompanying drawing, one-off process of the present utility model is described.
First screw workpiece 1 clamped with head of a bed chuck 7, use the top 6 top tight workpiece afterbodys of tail platform, then machine tool chief axis be linked into corresponding gear or have servomotor to adjust corresponding rotating speed, drive screw workpiece 1 rotates simultaneously.Roughing rubbing head 5 translation enters Working position, carries out polishing vertically to screw workpiece 1.Then, after roughing rubbing head 5 leaves processing cutting into position gradually, semifinishing rubbing head 4 enters Working position.Now, roughing rubbing head 5 need be lifted, after being adjusted to proper height difference with semifinishing rubbing head 4, more together screw workpiece 1 be processed.Other two rubbing head 2,3 actions by that analogy, finally complete the total order processing action to screw rod.
Described rubbing head is formed with motor-driven driving wheel and two driven pulleys and a regulating wheel by one, and the rear-face contact of all rollers and polishing abrasive belt, roller rotarily drives abrasive band and moves along roller tangential direction, once realizes the polishing to workpiece.The difference of roughing and fine finishining rubbing head is its amount of feeding in cutting direction, structurally not invariably with, be roughing and fine finishining rubbing head can arbitrarily be changed as required.
