Detailed Description
In order that those skilled in the art will better understand the present application, a technical solution in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will now be described in detail with reference to the accompanying figures 1-4, in conjunction with examples.
Example 1
Embodiment 1 discloses a scraper chain screw cutting tool, referring to fig. 1, the main part of the cutting tool includes a tool base 1, a fixing frame 2, a guide cylinder 3 and a tool bit rod 4, the tool base 1 is cut by waste steel plates, the fixing frame 2 is bent into an L shape by waste anchor rods, the lower end of the fixing frame is welded and fixed with the lower surface of the tool base 1, then the guide cylinder 3 is welded with the upper end of the fixing frame 2 and keeps a vertically downward state, and the guide cylinder 3 can be obtained by cutting steel pipes in a fixed length.
The cutter head rod 4 is arranged along the inner channel of the guide cylinder 3 in a penetrating way, and the cutter head rod 4 is formed by cutting and processing a steel rod in a fixed length. The upper end of the tool bit rod 4 is welded with a hammer head seat 5, and the hammer head seat 5 is in a round table shape with a wide upper part and a narrow lower part, so that the contact area between the tool bit and a hammer can be increased.
A cutting bit 6 is welded to the lower end of the bit rod 4, and the cutting bit 6 has an inverted triangle cross section, so that the cutting bit has a sufficient hardness. The check ring 7 is welded on the cutter head rod 4 between the cutter head 6 and the guide cylinder 3, and then the first spring 8 is connected between the check ring 7 and the lower end of the guide cylinder 3, so that the cutter head 6 can apply a pressing force to the nut on the scraper chain screw under the action of the first spring 8, and the screw is further kept fixed.
Finally, in the embodiment 1, a positioning block 9 is welded on the tool base 1 just below the cutting bit 6, and a positioning groove matched with the nut in size is machined on the positioning block 9.
When the cutting tool disclosed in this embodiment 1 cuts off the nut on the scraper chain screw, the operator manually pulls up the cutter head rod 4 upward against the force of the first spring 8 to separate the cutting cutter head 6 from the positioning block 9, then places the nut on the scraper chain screw to be cut off in the positioning groove, and then removes the force on the cutter head rod 4 to press the cutting cutter head 6 against the nut and fix it in cooperation with the limiting action of the positioning groove. Subsequently, the operator again uses the sledgehammer to hammer the hammer head seat 5, thereby effecting the cutting of the nut.
Example 2
Example 2 discloses a scraper chain screw cutting tool which is further optimally designed based on the technical scheme in example 1, and the same points as in example 1 are not explained again.
Referring to fig. 2, 3 and 4, a ring groove is formed in the outer circumferential surface of the upper end of the guide cylinder 3, and then a steel ring 10 is rotatably arranged in the ring groove, and the inner wall of the steel ring 10 is smoothly arranged, so that the friction resistance of the steel ring 10 when rotating around the ring groove is reduced. One or two symmetrical brackets 11 are welded on the outer surface of the steel ring 10, then a round hole is formed in the upper end of the bracket 11, a rotating shaft 12 is rotatably installed in the round hole, a poking bar 13 extending towards the direction of the cutter head rod 4 is welded at two ends of the rotating shaft 12, then a manual pressing rod 14 which inclines downwards is welded on the rotating shaft 12 between the two poking bars 13, and a second spring 15 is welded between the manual pressing rod 14 and the bracket 11.
Meanwhile, the tool bit rod 4 is welded with two convex columns 16 which are in action with the two poking strips 13, and the two convex columns 16 are symmetrically arranged and are all positioned above the poking strips 13 to be abutted against the poking strips 13.
