Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a threaded hole carbide tup, including hammer carrier 1, set up at the screw hole 101 at hammer carrier 1 top and set up the tup 2 in hammer carrier 1 bottom, hammer carrier 1's bottom is located and is provided with soft copper board 3 between hammer carrier 1 and the tup 2, soft copper board 3's texture is softer, can absorb partial impulsive force energy during the atress, four corners in top of hammer carrier 1 all are vertical fixedly connected with and run through hammer carrier 1 and soft copper board 3's fixing screw bolt 4, four corners in top of tup 2 all offer the fixing screw 203 that cooperation fixing screw bolt 4 used.

Specifically, as shown in fig. 1-3, the bottom fixedly connected with multiunit of tup 2 is the lug 201 that the rectangular array distributes, and multiunit lug 201 shape all is conical structure, the equal fixedly connected with of top four sides position department of tup 2 is the stopper 202 of vertical distribution, spacing groove 6 has all been seted up to one side that stopper 202 is close to in the outside of hammer seat 1 and soft copper plate 3, lug 201's setting, the area of contact of 2 bottoms of tup has been reduced, thereby the impact force when having promoted 2 hammering of tup, stopper 202 and spacing groove 6's setting, hammer seat 1 has been promoted, assemble fixed stability between tup 2 and the soft copper plate 3.

Specifically, as shown in fig. 1 and 2, preformed hole 7 has all been seted up in the outside that hammer seat 1 and soft copper sheet 3's inside is located fixing stud 4, and preformed hole 7 and fixing stud 4 are transition fit, fixing stud 4's outside is located the cover and is equipped with extrusion spring 5 between fixing stud 4 and the hammer seat 1, the setting of preformed hole 7, be convenient for fixing stud 4's interlude and fixed processing, chooseing for use of transition fit mode, the stability of being connected between hammer seat 1 and soft copper sheet 3 and the fixing stud 4 has been promoted, extrusion spring 5's setting, the impact force that can receive tup 2 on the one hand carries out elastic deformation buffering, on the other hand has promoted hammer seat 1, the stability of being connected between tup 2 and the soft copper sheet 3.

The working principle is as follows: when the hammer is used, the hammer seat 1 is screwed and installed on an output shaft of a punching and crushing device through the threaded hole 101, hammering can be carried out, when the hammer head 2 hammers crushed materials, the hammer head 2 can generate reverse impact force, so that the soft copper plate 3 between the hammer seat 1 and the hammer head 2 is extruded, the soft copper plate 3 with softer texture can absorb impact energy generated when the hammer head 2 hammers, meanwhile, the impact energy can be further transmitted to the hammer seat 1, the hammer seat 1 can extrude the extrusion spring 5 outside the fixing stud 4 under the action of the impact force, the extrusion spring 5 can generate elastic deformation, so that the impact force received by the hammer head 2 is further buffered by elastic deformation, after the hammer head 2 is locally damaged or broken, four groups of fixing studs 4 can be screwed out of the fixing screw holes 203 on the hammer head 2, the hammer head 2 can be detached, a new group of fixing screw holes 203 on the hammer head 2 is aligned to the fixing studs 4, and the fixing stud 4 is rotated, the fixing stud 4 is screwed into the fixing screw hole 203, and the replacement processing of the hammer head 2 is completed.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
