A kind of fin automatic finishing unit
Technical field
What the present invention relates to is a kind of automatic removing calibration devices of fin automatic finishing unit, the especially burr on aluminum plate-fin heat exchanger thermofin surface and flange, belongs to technical field of automation.
Background technology
Thermofin is the core part in aluminum plate-fin heat exchanger, after machine-shaping, may there is flange and the burr after local punching in thermofin, will have influence on the precision of fin, the brazing quality of the processing precision direct influence plate-fin heat exchanger of fin, finally affects the serviceability of heat exchanger.Yet burr and the flange that by artificial method, cannot effectively remove fin surface, not only can not guarantee that precision and production efficiency are lower.From the viewpoint of improving the machining accuracy of fin and production efficiency etc., be necessary to develop a kind of automatic finishing unit, can realize automatic finishing and the conveying of fin, in assurance fin machining precision, enhance productivity.
summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and propose a kind of simple to operate, the fin automatic finishing unit that improves fin machining precision and enhance productivity.
The object of the invention is to complete by following technical solution: described fin automatic finishing unit, it is mainly comprised of an automatic finishing machine and a ribbon conveyer, described ribbon conveyer be arranged on automatic finishing machine prime, this ribbon conveyer comprises a frame, two ends in frame are separately installed with half flexible roller that solderless wrapped connection has conveyer belt, and described conveyer belt is connected with the motor stopping with the driving that photoelectric sensor control active roller is installed by an active roller below frame;
Described automatic finishing machine mainly comprises upper and lower track base, line slideway auxiliary, isometry block, ball screw assembly,, finishing pinch roller, retainer plate, servomotor; Two pairs of line slideway auxiliaries connect firmly respectively on lower guideway seat and upper rail seat, the finishing pinch roller of bottom is connected with lower line slideway auxiliary with nut by nut seat, the finishing pinch roller on top is connected with upper line slideway auxiliary by slide block yoke plate, ball screw assembly, is connected with servomotor with big or small synchronizing wheel by arc tooth synchronous belt, be connected with the slide block of lower line slideway auxiliary simultaneously, the fin horizontal direction reciprocating rolling in order to the finishing pinch roller that completes bottom after punching shaping; Upper line slideway auxiliary is connected with upper line slideway auxiliary with connecting rod by yoke plate, completes the finishing pinch roller on top and the synchronous reciprocating of bottom finishing pinch roller and rolls, and finally completes the height tolerance up and down of shaping fin is carried out to finishing;
The height of described isometry block is set corresponding to fin height, and is installed on upper rail seat, in order to regulate the spacing between upper and lower two pairs of finishing pinch rollers, complete to differing heights fin finishing; Described retainer plate is installed on riser, for the retainer of fin, the roller for the location in fin width direction and transmission is installed on described retainer plate.
It is rational in infrastructure, simple to operate that the present invention has, and can automatically complete the height tolerance finishing of shaping fin is not affected to other parameter to comparatively desirable precision, the height relative tolerance of shaping fin can be controlled in 0.03 ~ 0.04mm; Can realize automatic finishing and the conveying of fin, the feature such as enhance productivity when guaranteeing fin machining precision.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, and a kind of fin automatic finishing unit of the present invention, it is mainly comprised of an automatic finishing machine 14 and a ribbon conveyer 15.Described ribbon conveyer 15 be arranged on automatic finishing machine 14 prime, be responsible for the conveying of shaping fin 21, this ribbon conveyer 15 comprises a frame 16, two ends in frame 16 are separately installed with half flexible roller 18 that solderless wrapped connection has conveyer belt 17, and described conveyer belt 17 is connected with the motor 20 stopping with the driving that photoelectric sensor control active roller is installed by an active roller 19 below frame 16.
Shown in Fig. 2-4, described automatic finishing machine mainly comprises upper and lower track base 2,1, line slideway auxiliary 3, isometry block 4, ball screw assembly, 7, finishing pinch roller 6, retainer plate 12, servomotor 10; Two pairs of line slideway auxiliaries 3 connect firmly respectively on lower guideway seat 1 and upper rail seat 2, the finishing pinch roller 6 of bottom is connected with lower line slideway auxiliary 3 with nut by nut seat, the finishing pinch roller 6 on top is connected with upper line slideway auxiliary 3 by slide block yoke plate, ball screw assembly, 7 is connected with servomotor with big or small synchronizing wheel by arc tooth synchronous belt 13, be connected with the slide block of lower line slideway auxiliary 3 simultaneously, the fin horizontal direction reciprocating rolling in order to the finishing pinch roller that completes bottom after punching shaping; Upper line slideway auxiliary 3 is connected with upper line slideway auxiliary with connecting rod 8 by yoke plate 9, completes the finishing pinch roller on top and the synchronous reciprocating of bottom finishing pinch roller and rolls, and finally completes the height tolerance up and down of shaping fin is carried out to finishing;
The height of described isometry block 4 is set corresponding to fin height, and is installed on upper rail seat, in order to regulate the spacing between upper and lower two pairs of finishing pinch rollers, complete to differing heights fin finishing; Described retainer plate 12 is installed on riser, for the retainer of fin, the roller 11 for the location in fin width direction and transmission is installed on described retainer plate 12.
The course of work of the present invention is: the fin 21 after shaping is transported to automatic finishing unit, the prime of finishing system is equipped be responsible for the being shaped conveying of fin of half flexible roller, the driving of roller with stop being controlled by photoelectric sensor, finishing system is by upper and lower a pair of limited roller, fin horizontal direction reciprocating rolling after punching is shaped, flange after the local punching that shaping fin may be existed and burr finishing one time, thereby the height relative tolerance of shaping fin is controlled in 0.03 ~ 0.04mm, this unit can be realized automatic finishing and the conveying of fin, when guaranteeing fin machining precision, enhance productivity.
