Abstract
The utility model relates to a reverse scraping cutter bar for a track link, which is suitable for a workpiece that has narrow perforation size space, cannot be processed by the common reverse scraping cutter, has low requirements for dimension precision and roughness and is required to be reversely processed. The reverse scraping cutter bar for the track link comprises a cutter bar connecting shaft, a pin, a cutter bar head, a cutter bar tail, a rivet, a washer, a nut and a white steel cutter bit and is characterized in that the cutter bar head, the cutter bar tail, the rivet, the washer, the nut and the white steel cutter bit are connected into a whole through riveting of the rivet and tightening of the nut to form the cutter bar for the track link; when the cutter bar is in use, the cutter bar connecting shaft and a main shaft Morse inner conical hole of a common vertical drilling machine are connected into a whole to be fixed on a main shaft, and then the cutter bar head for the track link passes through an inner hole of the workpiece; and the cutter bar is connected with the cutter bar connecting shaft through the pin, a power supply is started at the moment, and the processing can be carried out through reversely rotating a hand wheel of a machine tool. The cutter bar has the advantages of simple structure, low manufacturing cost of the tool, long service life, convenience in operation and high production efficiency.
Description
Technical field
The utility model relates to a kind of lathe knife bar, relates in particular to a kind of anti-knife bar of scraping of upright drill processing crawler belt joint.
Background technology
The hole dimension narrow space of crawler belt joint can't be processed with the common anti-cutter of scraping, and existing processing technology is for to be placed on workpiece on the horizontal milling machine workbench, use the milling cutter milling flat, this technology mode production efficiency is low, and cutter wear is fast, cause the processing cost height, and profile is not attractive in appearance.
The utility model content
The utility model is to overcome above-mentioned deficiency, has designed the anti-knife bar of scraping of crawler belt joint according to the processing request of workpiece.
The utility model is by the following technical solutions: the anti-knife bar of scraping of crawler belt joint is made up of knife bar connecting axle, pin, knife bar head, knife bar tail, rivet, packing ring, nut, white steel knife head.It is characterized in that it is crawler belt joint knife bar that knife bar head, knife bar tail, rivet, packing ring, white steel knife head connect as one by rivet and nut screwing clamping, knife bar head, knife bar tail are realized greater than 90 ° of rotations flexibly by needing rotation behind the rivet.Only the main shaft Mohs internal taper hole of knife bar connecting axle and common upright drill need be connected as one during use and be fixed on the main shaft, then crawler belt being saved knife rod head turns an angle and passes the workpiece endoporus, pin saves knife bar with crawler belt and is connected with the knife bar connecting axle, start power supply this moment, counter-rotating lathe handwheel can be processed.
The beneficial effects of the utility model: lever structure is simple, and it is low that worker is dressed up, and long service life is easy to operate, production efficiency height, the workpiece finished product good looking appearance that processes.
Description of drawings
As shown be knife bar figure.
1. knife bar connecting axle 2 is sold 3. knife bar heads, 4. knife bar tails, 5. rivets, 6. packing rings, 7. nuts, 8. white steel knife heads
The specific embodiment
As shown in the figure, knife bar connecting axle 1 is connected with the main shaft Mohs internal taper hole of common upright drill, knife bar head 3 is connected by pin 2 with knife bar connecting axle 1, knife bar head 3 is riveted by rivet 5 with knife bar tail 4, square opening matched in clearance in white steel knife head 8 and the knife bar tail 4, it is crawler belt joint knife bar that knife bar head 3, knife bar tail 4, rivet 5, packing ring 6, nut 7, white steel knife head 8 link into an integrated entity by rivet and nut screwing clamping.
Operation principle:
The knife bar connecting axle is connected with the main shaft Mohs internal taper hole of common upright drill and is one, be fixed on the main shaft, knife bar head, knife bar tail are realized greater than 90 ° of rotations flexibly by needing behind the rivet to rotate, crawler belt joint knife rod head turns an angle and passes the workpiece endoporus, pin saves knife bar with crawler belt and is connected with the knife bar connecting axle, start power supply this moment, counter-rotating lathe handwheel can be processed.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. crawler belt saves the anti-knife bar of scraping, it is characterized in that it is made up of knife bar connecting axle, pin, knife bar head, knife bar tail, rivet, packing ring, nut, white steel knife head, wherein knife bar head, knife bar tail, rivet, packing ring, nut, the steel knife head links into an integrated entity by rivet and nut screwing clamping in vain.
2. the anti-knife bar of scraping of crawler belt joint according to claim 1, it is characterized in that: the knife bar connecting axle is connected with the main shaft Mohs internal taper hole of upright drill, the knife bar head is connected by pin with the knife bar connecting axle, knife bar head and knife bar tail pass through rivet, the square opening matched in clearance in white steel knife head and the knife bar tail.
