Abstract
The utility model relates to a spanner for clamping or loosening the cutting tool and work piece of machine tool, which comprises a handle 1and a square head upright rod 2. The utility model is characterized in that: the rod body of the square head upright rod is configured with cascade shape; a through hole 6 is opened on the rod body with larger diameter; a sleeve 3 is positioned in coordination outside the rod body; a symmetric sealing groove 4 is arranged at the upper section of the sleeve 3; a square hole 5 that matches the square head of the square head upright rod 2 is positioned at the lower section of the sleeve 3; a connecting piece 7 is adopted to connect the square head upright rod 2 and the sleeve 3 via the sealing groove 4 and the through hole 6; a spring 8 is bushed inside the sleeve 3 opposite to the small diameter section of the square head upright rod 2. The utility model, with the advantages of simple structure, convenient and safe application, has the dual functions of the original chuck spanner and the square head screw spanner for cutter rest.
Description
Technical field
The utility model relates to processing equipment lathe used tool, is specially a kind of lathe and clamps fastening or loosen cutter and the used spanner of workpiece.
Background technology
Lathe is one of a kind of the most frequently used processing equipment.For a long time, engine lathe all uses two pairs of spanners: one pair of spanner is a chuck handle, is used for clamping fastening or loosens workpiece; Another pair is knife rest square head screw spanner, is used for clamping fastening or loosens cutter.People are accustomed to this, do not think to have what problem.But the inventor thinks that it has the following disadvantages: on the one hand, two pairs of spanners respectively have special use, can not replace usefulness, take by mistake easily, change frequent, cumbersome; On the other hand, when turner apprentice (or practice), regular meeting has just forgotten to take off and has driven after having apprentice (or classmate) to use the chuck handle clamping work pieces, the accident that spanner flies out and hurts sb.'s feelings occurs, and has hidden danger.
The utility model content
The technical problems to be solved in the utility model is the deficiency at above-mentioned technology, provide a kind of lathe with spanner, it is simple in structure, easy to use, safe, have former chuck handle and two pairs of plurality of advantages such as spanner function of knife rest square head screw spanner simultaneously.
The determine technical scheme of described technical problem of the utility model quasi-solution is: design a kind of lathe spanner, comprise handle 1, square toes vertical rod 2, the rod body that it is characterized in that square toes vertical rod 2 is divided into stepped, has a through hole 6 on the shaft of its major diameter part; Equipped sleeve 3 has symmetrical enclosed slot 4 in the upper end of sleeve 3 in the outside of shaft, in the lower end of sleeve 3 be and the square hole 5 of the square toes coupling of square toes vertical rod 2, utilizes connector 7 by enclosed slot 4 and through hole 6 square toes vertical rod 2 and sleeve 3 to be coupled together; In sleeve 3 with spring 8 of minor diameter counterpart suit of square toes vertical rod 2.
Characteristics of the present utility model are that former knife rest square head screw spanner and chuck handle are united two into one, and also promptly have the function of former knife rest square head screw spanner and chuck handle simultaneously, do not have the problem of taking by mistake, using mistake, and simple in structure, easy to use; Since sleeve 3 in the minor diameter counterpart of square toes vertical rod 2 spring 8 that designed suit, after using the utility model spanner to tighten workpiece release impressed pressure, rely on its elastic force, the state of deactivating automatically, avoided the generation of possibility casualty accident, safe in utilization.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof in detail the utility model is described in detail:
The lathe of the utility model design (is called for short spanner with spanner, referring to Fig. 1), comprise handle 1, square toes vertical rod 2, the rod body that it is characterized in that square toes vertical rod 2 is divided into stepped (referring to Fig. 2), its major diameter part is near handle 1, the square toes (square pole head) of the close square toes vertical rod 2 of small diameter portion, and on the shaft of its major diameter part, have a through hole 6; At the equipped sleeve 3 (referring to Fig. 3) in the shaft outside of square toes vertical rod 2, the internal structure shape of sleeve 3 is corresponding with the shape of described square toes vertical rod 2; Have symmetrical enclosed slot 4 in the upper end of sleeve 3, the length of enclosed slot 4 should satisfy in the square toes indentation sleeve 3 of square toes vertical rod 2 and the requirement of stretching out sleeve 3 outer certain-lengths; In the lower end of sleeve 3 be and the square hole 5 of the square toes coupling of square toes vertical rod 2 square groove 5 (referring to Fig. 4) in other words conj.or perhaps; Utilize connector 7 square toes vertical rod 2 and sleeve 3 to be coupled together, and make that connector 7 can relative slippage described enclosed slot 4 in by described enclosed slot 4 and through hole 6; In sleeve 3 with spring 8 of shaft minor diameter counterpart suit of square toes vertical rod 2.
The further feature of the utility model spanner is that described connector 7 is pin, be used for by sleeve 3 the above enclosed slot 4 both are connected as a whole with through hole 6 in the square toes vertical rod 2.The further feature of the utility model spanner can also be that described through hole 6 is screwed hole, the screw of described connector 7 for matching.This design is connected with loading and unloading square toes vertical rod 2 with the integral body of sleeve 3 all very convenient, and connection stability is also higher.
Operation principle of the present utility model is: in the ordinary course of things, spanner is retracted within the sleeve 3 by the effect of spring 8, also promptly cannot see the square toes of square toes vertical rod 2, and the bottom face certain depth of the interior recessed sleeve 3 of the square toes bottom face of square toes vertical rod 2.This degree of depth should be not less than the height of the lathe tools fastening screw head of a nail.This design can make the utility model spanner directly substitute former lathe saddle square head screw spanner, directly finishes the function of former lathe saddle square head screw spanner in other words; When the utility model spanner is used for fastening (or loosening) chuck clamping (or release) workpiece, only need press down handle 1, promptly apply some axial forces, overcome the elastic force of described spring 8, make the square toes of wrench square head vertical rod 2 stretch out sleeve 3, cause the duty the same to have the same function of former lathe chuck spanner in other words, inject in the square hole of chuck, finish the work that clamps or discharge workpiece with former lathe chuck spanner.After work was finished, one loosed one's grip or no longer applies the power that presses down handle 1, because the active force of spring 8, the square toes of wrench square head vertical rod 2 will withdraw from the square hole of chuck automatically, be withdrawn in the sleeve 3, involution off working state or conventional static condition break away from lathe chuck simultaneously.This design can not miss the utility model spanner and stays on the lathe chuck, has guaranteed safe in utilization.
