The gear-milling head-hanging mechanism is formed from clamp device, drive shaft, milling shaft, gear milling cutter and angular gear, and the changegear longitudinal moving graduaction gear-milling mechanism is formed from miller working table, index head, longitudinal screw rod, driving gear, transmission gear and driven gear.
Description
Technical field:
The present invention relates to a kind of processing unit (plant) of tooth bar, especially a kind of processing unit (plant) that on common horizontal milling machine, adds section chief's tooth bar.
Background technology:
At present, the processing of tooth bar is normally processed by the gear rack machine of special use.Under the situation that does not have the tooth bar special processing equipment, utilize the horizontal mobile manufacturing gear strip of common horizontal milling machine usually, but limited because of the infeed stroke of lathe, cause the maximum length of energy manufacturing gear strip also very limited.If want tooth bar that processing length surpasses the infeed stroke scope with regard to dying.In the production process of enterprise, need to use the tooth bar of some longer dimensions usually, but use conventional processing method can't process again.Because part is special, and for small lot batch manufacture, carries out cooperation processing if deliver to special tooth bar processing factory, not only processing cost increases, and will influence the manufacturing schedule of this product, product is paid delayed, and enterprise is caused the certain economic loss.
Summary of the invention:
The objective of the invention is to: provide a kind of can be on common horizontal milling machine small lot add section chief's tooth bar and convenient and simple for operation, the processing unit (plant) of long tooth bar reliably, to realize the manufacturing certainly of long tooth bar, thereby reduce cost, increase economic efficiency, solve the problem that prior art exists.
The present invention constitutes like this: it is vertically moved apart from calibration mill teeth mechanism by mill teeth hanging head mechanism and change gear and forms, mill teeth hanging head mechanism is made of anchor clamps (2), driving shaft (3), milling spindle (9), gear milling cutter (7), helical gear (4), anchor clamps (2) are installed on the lathe by the dovetail groove of itself, and with locking pull bar (1) fixing and locking; Milling spindle (9) and driving shaft (3) are contained on the anchor clamps (2), and gear milling cutter (7) is contained on the milling spindle (9), and milling spindle (9) links to each other with driving shaft (3) by helical gear (4); Change gear vertically moves apart from calibration mill teeth mechanism and is made of milling machine table (11), dividing head (15), vertical screw mandrel (17), driving gear (13), travelling gear (12) and driven gear (16), dividing head (15) is contained on the milling machine table (11), and be connected with driving gear (13), driving gear (13) and travelling gear (12) engagement, travelling gear (12) and driven gear (16) engagement, driven gear (16) is contained on vertical screw mandrel (17), and vertically screw mandrel (17) is contained in the milling machine table (11).
In the processing unit (plant) of above-mentioned long tooth bar, milling spindle (9) and driving shaft (3) use lining (10), packing ring (6) and nut (5) to be installed on the anchor clamps (2) respectively.
In the processing unit (plant) of aforesaid long tooth bar, milling spindle (9) and driving shaft (3) are 90 degree mutually and are installed on the anchor clamps (2).
In the processing unit (plant) of above-mentioned long tooth bar, gear milling cutter (7) is contained on the milling spindle (9) by key (8), packing ring (6) and nut (5).
The invention solves prior art and on common horizontal milling machine, can't add the technical barrier of section chief's tooth bar, adopt the present invention directly on common horizontal milling machine, can process required long tooth bar, realized the manufacturing certainly of long tooth bar, need not deliver to special tooth bar processing factory and carry out cooperation processing, not only reduced production cost, and can be from the main control manufacturing schedule, avoiding paying extension because of the product of cooperation processing influences the whole production progress, has improved economic benefit of enterprises.
Description of drawings:
Fig. 1 is the structural representation of mill teeth hanging head of the present invention mechanism;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 vertically moves apart from the structural representation of calibration mill teeth mechanism for change gear of the present invention.
The specific embodiment:
Get final product the technical barrier of the long tooth bar of hoshu, embodiments of the invention: it is vertically moved apart from calibration mill teeth mechanism by mill teeth hanging head mechanism and change gear and forms, wherein mill teeth hanging head mechanism constitutes (as shown in Figure 1, 2) by anchor clamps 2, driving shaft 3, milling spindle 9, gear milling cutter 7, helical gear 4, anchor clamps 2 are installed on the lathe by the dovetail groove of itself, and with locking pull bar 1 fixing and locking; Milling spindle 9 and driving shaft 3 are installed on the anchor clamps 2 with lining 10, packing ring 6 and nut 5 respectively, milling spindle 9 links to each other with driving shaft 3 by helical gear 4, and milling spindle 9 is 90 degree mutually with driving shaft 3 to be installed, and utilizes engaged transmission between the helical gear 4 to change the cutting direction of milling spindle 9, and driving shaft 3 connects motor.Gear milling cutter 7 is fixed on the milling spindle 9 by key 8, packing ring 6 and nut 5.During work, driving shaft 3 rotates under the driving of motor, and the engaged transmission by helical gear 4 rotates milling spindle 9, and cutting direction changes 90 °, rotation driven gear milling cutter 7 rotations of milling spindle 9, thus finish the mill teeth process.Change gear vertically moves apart from calibration mill teeth mechanism and constitutes (as shown in Figure 3) by milling machine table 11, dividing head 15, vertical screw mandrel 17, driving gear 13, travelling gear 12 and driven gear 16, and milling machine table 11 is used to place tooth bar to be processed.Dividing head 15 is contained on the milling machine table 11, and is connected with driving gear 13, driving gear 13 and travelling gear 12 engagements, and travelling gear 12 and driven gear 16 engagements, driven gear 16 is contained on vertical screw mandrel 17, and vertically screw mandrel 17 is contained in the milling machine table 11.When rotating the dividing head handle 14 of dividing head 15, driving gear 13 rotates, and by gears engaged travelling gear 12 is rotated, and driven gear 16 is by driven thereupon with the engagement of travelling gear 12; When driven gear 16 rotated, vertically screw mandrel 17 rotated thereupon, moved thereby drive milling machine table 11, and displacement shows that on the dial of dividing head 15 the each scale value of rotating of index dial is a tooth pitch.When the racks processed tooth pitch changes, only need to change gear milling cutter 7, and change driving gear 13, travelling gear 12 and driven gear 16, change its gearratio and get final product.
