Description
Technical field
The invention relates to the rod-pulling type cutting machine, and particularly a kind of cutting machine of when packed and transported, being convenient to splits into support and the rod-pulling type cutting machine pull bar self-locking device that cuts head.
Background technology
The rod-pulling type cutting machine is the desk-top very widely cutting tool of a kind of application, many, the huge market demand of cutting function, and existing rod-pulling type cutting machine upper connecting rod and pull bar front stall generally adopt interference fit; Press-fit with hydraulic press, use screw fastening again, this kind fit can't realize disassembling fast support and cutting head; Even apart packing can be taken support and cutting head by producer; The user also can't accurately assemble, and can only integral type pack when therefore existing rod-pulling type cutting machine is packed, and can not split the packing that comes; The subject matter that exists has: one because the integral type packaging volume is big; It is also big to retain the space, and required inserts is just many, causes packing of product cost high always; The 2nd, because the integral type packaging volume is big, the vanning amount is just little, is example with the rod-pulling type cutting machine of diameter 255, and a container can only be adorned 140; Can adorn 240 more than by our new design scheme, the 3rd, because the integral type packaging volume is big, the breakage rate in the packed and transported process is high; Reach about 8/1000ths, therefore develop a kind of quick, simple and easy; Fit realizes that the split-type packing of cutting machine becomes a difficult problem in the industry reliably.For this reason, many manufacturers and knowledgeable people research and develop to the problems referred to above, but do not have desirable product on market, to emerge so far as yet.
Summary of the invention
Can not split the existing the problems referred to above of packing for overcoming existing rod-pulling type cutting machine, the purpose of the invention provide a kind of simple and reasonable, the vanning amount is big, packed and transported convenient, production cost is low, breakage rate is low, the product precision is unaffected, the rod-pulling type cutting machine pull bar self-locking device that can the Rapid Realization pull bar be connected with the pull bar front stall.
The invention solves the problems of the technologies described above the technical scheme that is adopted; It comprises that pull bar back seat, pull bar, pull bar are from lock set, pull bar front stall; Pull bar is fixed on the pull bar back seat, and pull bar is in lock set is installed in pull bar, and described pull bar comprises housing, pull bar self-locking sliding pin, stage clip and self-lock pin from lock set; Pull bar self-locking sliding pin is slidably disposed in the housing; The middle part of pull bar self-locking sliding pin is provided with the kidney groove, is provided with first, second and the 3rd positioning on the kidney groove successively, self-lock pin can correspondence be arranged on first, second with the 3rd positioning on; Stage clip is contained on the spring mounting hole of self-lock pin and withstands on the inwall of housing, and housing is provided with the housing lockhole that matches with self-lock pin; Described pull bar is provided with the pull bar lockhole that matches with self-lock pin; Described pull bar front stall is provided with the front stall lockhole that matches with self-lock pin.
When described self-lock pin was in first positioning, the head of self-lock pin stretched in the housing lockhole of housing.
When described self-lock pin was in second positioning, the head of self-lock pin stretched in the housing lockhole and pull bar lockhole of housing.
When described self-lock pin was in the 3rd positioning, the head of self-lock pin stretched in housing lockhole, pull bar lockhole and the front stall lockhole of housing.
The inner of said pull bar self-locking sliding pin is provided with the elasticity limited step, is provided with first boss and second boss that match with the elasticity limited step in the housing.
Described pull bar is provided with the pull bar positioning, and housing is provided with the outside fix that matches with the pull bar positioning.
Described housing is formed by the mutual buckle of left and right sides housing.
After adopting said structure, following advantage and effect are arranged compared with prior art: the one, because the pull bar front stall can split with pull bar fast,, packs the cutting head so just can splitting with support; Rod-pulling type cutting machine with diameter 255 is an example,, the packing case volume can dwindle 40%; Packing cost can descend 40%; The vanning amount is big, and a container can be adorned 240, and breakage rate is reduced to about 2/1000ths.The 2nd, after employing split structure, the cutting machine precision was unaffected, firm and reliable connection.
