Description

Double-rotation automatic indexing bidirectional planer
Technical Field
The utility model relates to a metal planing processing equipment, especially a two-way curved surface planing machine.
Background
The bidirectional curved surface planing machine is a professional machine for planing and processing Roots blower impellers, has good rigid structure and manufacturability, the consistency of the batch planing processing precision of the Roots blower impeller can be ensured, the requirement of the Roots blower on the size precision of impeller pairing is ensured, the Roots blower impeller is mature and applied to processing of the Roots blower impeller with the planing size of 300-1000 mm and with two to four straight-tooth impeller profiles, a machine tool can automatically control the bidirectional planer tool to reciprocate after clamping the impeller to be processed through the configured numerical control rotary indexing clamping device mechanism, and the planing processing can be started from the current impeller profile, after the profile is processed, the indexing mechanism is controlled to accurately turn and index to the second fan blade profile of the impeller, then the surface is planed, and the turnover mechanism is matched with the bidirectional planer tool to sequentially turn over and plane each molded surface of the impeller. Taking a planer to process a two-blade impeller workpiece as an example, the processing flow can be summarized as clamping a workpiece, checking a datum for tool setting, setting processing parameters, planing a first surface, turning a dividing mechanism 180 degrees, planing a second surface, loosening and clamping the workpiece after planing, if the workpiece redundancy is large and multiple tools are needed to plane to a size, the two steps of turning the impeller and planing are repeated for many times in the flow, if the calculation is carried out from the whole impeller processing time period, the time occupied by the clamping workpiece and the datum for tool setting and checking is auxiliary time which is generally relatively fixed, the reciprocating operation time of the two-way planer is the actual effective planing time, the larger the workpiece is, the longer the planing time is, therefore, the larger the effective planing time is, the higher the speed of the two-way planer is favorably increased, the planing efficiency is higher, and for planing the impeller workpiece with the general size length of 300-1000, the workpiece with the length can fully exert the advantages of high speed and high efficiency of the planer due to large planing stroke and long distance, but if the planer is used for planing smaller-sized impellers, such as impellers with the length of 200 or less, the planing stroke is very short due to the small length, the speed is not easy to be improved, the effective planing time is short, and the planing efficiency is much lower compared with that of the large-sized impellers, on the other hand, when the planer is used for processing the workpieces with the smaller size, the planing feed amount in one stroke is small, the bearing force of a ram and a workbench is small, the power allowance is too large, waste and waste are not economical, the workbench is slightly empty and the utilization rate is not high, so that the overall processing efficiency is low, the characteristics of high-speed and high-efficiency planing processing of the bidirectional planer cannot be fully exerted, if the existing planer is proportionally reduced and redesigned to be specially used for processing the small-sized impellers, the performance of the bidirectional planing high-speed operation is limited, and the application range of the special machine is narrow and is more uneconomical.
SUMMERY OF THE UTILITY MODEL
Speed is not high when overcoming current lathe for the impeller of machined dimension below 200, and the less not enough of efficiency, the utility model provides an adopt two automatic graduation fixture of gyration, but once two impellers of centre gripping, when the upset is being done to the centre gripping impeller, can make two indexing means can be synchronous coaxial syntropy the same angle of upset to guarantee that two impeller profiles of clamping on two fixture above are still parallel respectively after the upset, make two-way planer tool stroke can dig two impeller work pieces, and ensure that two-way planer tool digs the technological dimension uniformity precision of two impeller processing profiles after the past.
The utility model adopts the technical proposal that: a bidirectional curved surface planing machine is composed of a rigid frame with a bearing structure, a ram for reciprocating movement on the cross beam of frame, a planing tool mechanism on the vertical carriage in the middle of ram, and a dual-direction planing tool mechanism 200420026963.0 on the bench of machine and with two high-precision automatic indexing clamper whose end faces are coaxial and able to rotate coaxially, synchronously and at the same angle The blade wheel is turned over coaxially, in the same direction and at the same angle, so that the blade wheel is matched with the bidirectional planing tool to plane each molded surface of the blade wheel in a circulating and reciprocating mode.
The beneficial effects of this planer adoption dual-rotation automatic graduation fixture are that, two-way planer adopts dual-rotation automatic graduation clamping device, can once the clamping two work pieces, and only need once to good the sword, alright to the coaxial synchronous planing of two impellers of centre gripping, single clamping impeller of comparison carries out tool setting planing processing, clamping tool setting number of times has been reduced, single planing stroke has been increaseed, be favorable to in effective processing length, can be with the planing processing of bigger speed, machining efficiency has been improved effectively, the required total time of batch work piece processing has been shortened, to the error uniformity technology of batch processing impeller work piece, and the impeller surface finish quality that higher speed brought improves, more have positive effect, make the planing processing of impeller, can alleviate intensity of labour, it has practical meaning to reduce the processing cost.
