Abstract
The utility model discloses a tapping machine screw tap protection device which is composed of a sleeve, a pressure spring, a return spring and a screw lead component. The sleeve is fixedly arranged on a tapping machine body, the screw lead component is arranged in the sleeve, one end of the screw lead component is used for assembling a screw tap, and the other end of the screw lead component is matched with a rotation output mechanism on the tapping machine. The pressure spring and the return spring are both arranged in the sleeve and are both matched with the screw lead component and the sleeve. The pressure spring and the return spring are arrayed vertically, one end of the return spring is matched with the sleeve in a connecting mode, and the other end of the return spring is matched with the screw lead component in a connecting mode. One end of the pressure spring is matched with the sleeve in a connecting mode, and the other end of the pressure spring is matched with the screw lead component in a connecting mode. Compared with the prior art, the tapping machine screw tap protection device is simple in structure, reasonable in design, good in universality, suitable for being used in various tapping machines, and capable of effectively preventing the screw tap and threads from being damaged.
Description
Technical field
The utility model relates to a kind of aperture processing machine, relates to a kind of tapping machine screw tap protective device in particular.
Background technology
The tapping machine is the machining equipment that a kind of medial surface of hole of the part in various through holes with different size such as parts housing, equipment end face, nut, ring flange or blind hole processes internal thread, screw or makes tooth buckle.The tapping machine also is tapping machine, screw thread tapping machine, thread tapping machine, automatic screw machine etc.
The machining process of tapping machine is, screw tap on the tapping machine is done straight line ramming motion and rotation under the cooperation of slider of punch and tapping machine drives, realize tapping processing is carried out in the hole on the part, after tapping is finished, screw tap is done the counter-rotating campaign and is moved along reverse linear, withdraws from the hole.
On the existing tapping machine; on the rigid installation tapping of the screw tap machine; tapping machine and screw tap are fixed as one; in the process of reality; usually can owing in the punching course because feeding is inaccurate or the red needle breakage problem; cause screw tap and the pre-deviation that needs tapping too big or when not having pre-punched hole, can cause that screw tap is rigid answers back to material downwards and fracture.After simultaneously screw tap is finished the extrusion modling screw thread to the hole, drive screw tap when slider of punch up moves and withdraw from screwed hole, screw tap can with screwed hole in screw thread rigid pullling taken place, cause screw thread impaired.
The utility model content
The purpose of this utility model is to overcome existing deficiency in the prior art, provides a kind of and can avoid that screw tap is rigid answers back to material downwards and fracture and avoid screw tap to break the tapping machine screw tap protective device of screw thread.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
Tapping machine screw tap protective device of the present utility model is by sleeve, compression spring, return spring, and the helical pitch assembly constitutes.
Sleeve is fixedly mounted on the tapping machine body;
The helical pitch assembly places in the sleeve;
Helical pitch assembly one end is used for the assembling screw tap, and the other end matches with rotation output mechanism on the tapping machine;
Compression spring and return spring are installed in the sleeve and all cooperate with described helical pitch assembly and sleeve;
Compression spring, return spring are up and down to be arranged;
One end of return spring is connected cooperation with sleeve, the other end is connected cooperation with the helical pitch assembly;
One end of compression spring is connected cooperation with sleeve, the other end is connected cooperation with the helical pitch assembly.
During the utility model work,
1, the descending tapping protection of screw tap: when the inaccurate or red needle breakage problem owing to feeding in the punching course, cause screw tap and the pre-hole deviation that needs tapping too big or when not having pre-punched hole, screw tap withstands material surface and when descending in tapping mechanism, the helical pitch assembly squeeze pressure camber of spring that links to each other with screw tap, make the related screw tap of helical pitch assembly along the certain buffer distance of sleeve rollback, screw tap can not fractureed with the rigid bump of material, the protection screw tap does not damage to greatest extent;
2; prevent the damaged protection of screw thread: tapping finishes; screw tap material in back off procedure has one and removes to spur screw tap down and compression retracteding position spring by the reaction force that is threaded; allow screw tap together with helical pitch assembly integral body with pulling force down the servo-actuated power of unloading recess material fully up to screw tap; avoid screw tap to break or attacked screw thread and pull, guaranteed the qualified screw thread of thread forming tap tapping on product.
The utility model compared with prior art, and is simple in structure, reasonable in design, and versatility is good, in all types of tapping machines, prevents that effectively screw tap from damaging and screw thread is impaired.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structural upright schematic diagram of the present utility model.
The specific embodiment
For conveniently understanding the utility model, the utility model will be further described below in conjunction with accompanying drawing.
Embodiment:
Among the figure, sleeve 1 is fixedly mounted on the tapping machine body;
One end of return spring 5 is connected cooperation with sleeve 1, and the other end is connected cooperation with helical pitch assembly 2;
One end of compression spring 4 is connected cooperation with sleeve 1, and the other end is connected cooperation with helical pitch assembly 2.
The above, only be preferable enforcement of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize above-mentioned technology contents to be changed or be modified to the equivalent embodiment of equivalent variations, at this, all the technical solution of the utility model contents that do not break away from, just foundation technical spirit of the present utility model all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
