Abstract
The utility model discloses a tool for dismantling a positioning pin of a fretsaw guide wheel. The tool for dismantling the positioning pin of the fretsaw guide wheel comprises a support plate, a handle, a main screw rod and a vice screw rod. The middle of the handle is fixedly connected with the tail end of the main screw rod and forms the shape of T. The vice screw rod is fixedly connected at the front end of the main screw rod and coaxial with the main screw rod. Directions of threads on the main screw rod and the vice screw rod are opposite. A threaded hole is arranged in the middle of the support plate and matched with the threads of the main screw rod. The tool for dismantling the positioning pin of the fretsaw guide wheel has the advantages that the main screw rod is matched with the support plate in a threaded mode and the directions of the threads on the main screw rod and the vice screw rod are opposite. The vice screw rod is screwed into the positioning pin and then the support plate is rotated so that the support plate is contacted with an end face of the guide wheel. During the process of rotating the main screw rod, the threads of the positioning pin and the vice screw rod are tightly screwed so as to achieve that the positioning pin is rapidly dismantled without manual prying. Labor intensity is reduced, a coating of the guide wheel is protected from being scraped in prying and safety of operational staff is ensured.
Description
Technical field
The utility model relates to a kind of scroll saw kit, particularly a kind of guide wheel disassembling positioning pin frock.
Background technology
Now when dismounting guide wheel alignment pin, do not have special instrument, just be screwed to inside the alignment pin with the screw of M6, then with iron pipe or other instrument prize make its a little unload, sometimes exerted oneself conference hurt the guide wheel coating or since contact-making surface inadequate, firmly prize easily injured.
The utility model content
Technical problem to be solved in the utility model provides a kind of guide wheel disassembling positioning pin frock, by main screw mandrel and paranema bar screw thread are oppositely arranged, and be combined with gripper shoe and realize scroll saw guide wheel alignment pin quick-detachment, raise the efficiency, reduce labour intensity, avoid gouge guide wheel coating.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of scroll saw guide wheel disassembling positioning pin frock comprises gripper shoe, handle, main screw mandrel and paranema bar; Described handle middle part is fixedly connected with main screw mandrel end and is T-shaped, and described paranema bar is fixedly connected on main screw mandrel front end and coaxial with main screw mandrel; The hand of spiral of described main screw mandrel and paranema bar is opposite; Described gripper shoe middle part is provided with screwed hole and cooperates with main wire rod thread.
Described gripper shoe is the cuboid platy structure.
The terminal welding of described handle and main screw mandrel.
The beneficial effect that adopts technique scheme to produce is: main screw mandrel and gripper shoe threaded engagement, and the hand of spiral of paranema bar and main screw mandrel is opposite, after the paranema bar is screwed into alignment pin, the rotational support plate, gripper shoe is contacted with the guide wheel end face, backward rotation master's screw mandrel, main screw mandrel is back-outed from the screwed hole of gripper shoe, because the hand of spiral of paranema bar is opposite with the hand of spiral of main screw mandrel, in backward rotation master's screw mandrel process, the screw thread of paranema bar and alignment pin is in tight condition always, realize the alignment pin quick-detachment, need not manually to prize, reduce labour intensity, avoid prizing gouge guide wheel coating in the process, guarantee operator safety.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In the accompanying drawings: 1, handle; 2, gripper shoe; 3, paranema bar; 4, main screw mandrel.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
A kind of scroll saw guide wheel disassembling positioning pin frock as shown in Figure 1 comprises gripper shoe 2, handle 1, main screw mandrel 4 and paranema bar 3; Described handle 1 middle part is fixedly connected with main screw mandrel 4 ends and is T-shaped, and described paranema bar 3 is fixedly connected on main screw mandrel 4 front ends and coaxial with main screw mandrel 4; The hand of spiral of described main screw mandrel 4 and paranema bar 3 is opposite; Described gripper shoe 2 middle parts be provided with screwed hole and with main screw mandrel 4 threaded engagement, described gripper shoe 2 is the cuboid platy structure, described handle 1 and main screw mandrel 4 terminal welding.
Goal of the invention of the present utility model is to adopt the screw mandrel quick-detachment guide wheel alignment pin of opposite direction, wherein the effect of handle is the convenient main screw mandrel 4 that rotates, and the effect of paranema bar is to cooperate with the screwed hole of alignment pin, and the effect of supporter provides reverse support force when being as the dismounting alignment pin; In concrete application process, at first the paranema bar is screwed in the alignment pin endoporus, realize the location of main screw mandrel and paranema bar, then rotational support plate on main screw mandrel, make gripper shoe and guide wheel end contact, and chucking guide wheel, this moment rotary handle, direction of rotation is identical with the hand of spiral of paranema bar screw thread, does not have relative motion between paranema bar and the alignment pin, but because main screw mandrel is opposite with the hand of spiral of paranema bar, so the relative gripper shoe of main screw mandrel is outwards moved in rotary course, thereby alignment pin is extracted, after extracting alignment pin pulled down from the paranema bar and get final product, whole process need not to use hard thing to prize alignment pin, reduces labour intensity, prevents hard thing gouge guide wheel coating, also can avoid endangering operator safety, improve guide wheel disassembling positioning pin efficient.
