Abstract
The utility model provides a device for testing the pulling force of a saw chain. The device comprises an oil pressure mechanism and a second fixed end which are respectively and fixedly arranged at two ends of a base, as well as a first fixed end positioned between the oil pressure mechanism and the fixed end, wherein the first fixed end is slidably connected with the base; a piston rod of the oil pressure mechanism stretches out and draws back so as to enable the first fixed end to be close to or far away from the second fixed end; the two fixed ends are provided with grooves for fixing the saw chain; and the cross sections of the two grooves are positioned on the same horizontal plane. The device for testing the pulling force of the saw chain, provided by the utility model is simple in structure and can be used for effectively testing the pulling force bearing capability of the saw chain.
Description
Technical field
The utility model relates to a kind of performance testing device of electric chain saw, particularly a kind of saw chain device for testing tensile force.
Background technology
The disclosed electric chain saw of prior art, its principle of work are that motor rotor is provided with gear with the power drives motor, thereby the follower gear that drives on the transmission shaft through driving gear drives sprocket gear, and sprocket gear drives saw chain, and saw chain is slided at a high speed on guide rod.For making electric chain saw have maximum sawmilling ability; Need to use large capacity motor to improve the rotating speed of driving gear; Improve the rotating speed of follower gear indirectly; Thereby improve the speed that saw chain slides on guide rod,, make that also saw chain needs to tolerate bigger tension force because the high speed of saw chain on guide rod slides.Yet, in the prior art, there is not the instrument of test saw chain tension force, and after saw chain is produced, directly puts on market, in follow-up use, there is bigger potential safety hazard.
The utility model content
The utility model provide a kind of simple in structure, can the Validity Test saw chain to the saw chain device for testing tensile force of the ability to bear of pulling force.
The utility model solves the problems of the technologies described above through following technical scheme; The utility model proposes a kind of saw chain device for testing tensile force; Comprise the oil sector and second stiff end that are fixed in the base two ends; Be in first stiff end between said oil sector and the said second stiff end said base that is slidingly connected; The piston rod of said oil sector is flexible can make said first stiff end near or away from said second stiff end, two groups of said stiff ends are equipped with the groove of fixing said saw chain, the section of two groups of said grooves is at same surface level.
Preferably, said stiff end comprises column, is fixed on the fixed head on the said column, the threaded main shaft of welding on the said fixed head, and axle sleeve entangles said main shaft and locked by the nut that cooperates said main shaft, and said groove is opened in said axle sleeve outer wall.
Preferably, the control gear that also comprises the said piston rod pulling force of controlling said oil sector.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
This apparatus structure is simple, is easy to use, and can carry out tensile test to saw chain very easily.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structure diagram of embodiment 1 in the utility model;
Fig. 2 is a part-structure enlarged diagram in the utility model;
Fig. 3 disassembles synoptic diagram for part-structure in the utility model;

Embodiment
Following embodiment and Fig. 1-3 pair the utility model of combining is described further:
Embodiment 1
A kind of saw chain device for testing tensile force; Comprise the oil sector 1 and the second stiff end 4b that are fixed in base 3 two ends; Be in the first stiff end 4a between the oil sector 1 and the second stiff end 4b base 3 that is slidingly connected; The piston rod 2 of oil sector 1 is flexible can make the first stiff end 4a near or away from the second stiff end 4b, the first stiff end 4a, the second stiff end 4b are equipped with the fixedly groove of saw chain, the section of two groups of grooves is at same surface level.The first stiff end 4a, the second stiff end 4b include column 45, are fixed on the fixed head 41 on the column 45, the threaded main shaft 43 of welding on the fixed head 41, and axle sleeve 42 entangles main shaft 43 and locked by the nut 44 that cooperates main shaft 43, and groove is opened in axle sleeve 42 outer walls.The control gear that also comprises piston rod 2 pulling force of controlling oil sector 1.
The utility model is not limited thereto embodiment, and the related realization assembly that is the basis with the utility model thought is all in the protection domain of the utility model.
Claims (3)
1. saw chain device for testing tensile force; It is characterized in that; Comprise the oil sector and second stiff end that are fixed in the base two ends, be in first stiff end between said oil sector and the said second stiff end said base that is slidingly connected, the piston rod of said oil sector is flexible can make said first stiff end near or away from said second stiff end; Two groups of said stiff ends are equipped with the groove of fixing said saw chain, and the section of two groups of said grooves is at same surface level.
2. a kind of according to claim 1 saw chain device for testing tensile force; It is characterized in that; Said stiff end comprises column, is fixed on the fixed head on the said column; The threaded main shaft of welding on the said fixed head, axle sleeve entangles said main shaft and locked by the nut that cooperates said main shaft, and said groove is opened in said axle sleeve outer wall.
