Background technology
Grinding machine utilizes grinding tool to carry out the lathe of grinding to surface of the work, most grinding machine uses the emery wheel of high-speed rotation to carry out grinding, minority be use other grinding tools such as oilstone, abrasive band and free abrasive to process, as grinding machine, superfinisher, abrasive belt grinding machine, grinder and polishing machine etc.
The horizontal automatic feed mechanism of bistrique on digital control plain surface grinding machine of the prior art generally adopts hydraulic-driven, horizontal hand feed adopts rack pinion, because the rack-and-pinion of the piston rod of ram pot and manual lateral feeding can not accurately be located, so feed accuracy is not high, working strength is large, automatic and hand feed needs to be changed by handle, complicated structure, operation is inconvenient and efficiency is low.
Utility model content
It is not high that the utility model overcomes bistrique transverse feed mechanism feed accuracy in prior art, the deficiency that working strength is large, provides one can significantly improve bistrique traverse feed precision, the grinding wheel feed mechanism of the person's of lightening one's labor working strength.
For achieving the above object, the utility model is by the following technical solutions:
A kind of bistrique transverse feed mechanism, it comprises planker and is arranged on the bistrique below planker, be provided with in described planker for the feed mechanism with rotary bistrique traverse feed movement, described feed mechanism is by servomotor, planetary reduction gear, shaft coupling, ball-screw, ball-screw nut seat and bearing block composition, described servomotor is connected with planetary reduction gear, described planetary reduction gear is connected with shaft coupling, described shaft coupling is connected with ball-screw, described ball-screw nut seat is arranged in the middle part of ball-screw, described ball-screw nut seat is fixedly connected with bistrique, described bearing block is arranged on ball-screw two ends respectively.
Feed mechanism by being made up of servomotor, planetary reduction gear, shaft coupling, ball-screw, ball-screw nut seat and bearing block in the technical program is replaced in prior art and is adopted hydraulic-driven, horizontal hand feed generally adopts the feed mechanism of rack pinion, thus the precision of bistrique traverse feed is improve by the work of the drive disk assembly such as servomotor, planetary reduction gear, make precision reach 0.005mm.
Further technical scheme is, is provided with the thrust angular contact bearing cooperatively interacted with ball-screw in described bearing block.
By being provided with the thrust angular contact bearing cooperatively interacted with ball-screw in bearing block in the technical program, used by the pairing of thrust angular contact bearing, starting torque is little, achieves low driving force running at high precision.
Further technical scheme is, described servomotor is electrically connected with the digital control system for controlling its work.
By being electrically connected with digital control system on servomotor in the technical program, thus it is digital control to achieve servomotor, realizes the horizontal auto-feed of bistrique.Control grinding wheel feed by the mode of numerical control and also reach the effect improving feed accuracy simultaneously.
Further technical scheme is, is provided with shower nozzle outside described bistrique.
Being provided with shower nozzle by taking the photograph outside bistrique in the technical program, just the scrap that bistrique produces in grinding process can being rinsed well by shower nozzle.
Further technical scheme is, described bistrique comprises bearing shell bistrique, rolling bearing bistrique and dynamic and hydrostatic bearing bistrique.
By selecting different types of bistrique just can meet various processing request in the technical program, be convenient to the replacing of bistrique.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, rationally, and reliable operation.Bistrique traverse feed precision can be significantly improved, the person's of lightening one's labor working strength.Make surface grinding machine can realize NC postprocessing, automation, improve machining accuracy and the automaticity of grinding machine.
