Abstract
The utility model relates to a kind of pick grip device of monodentate coal petrography cutting test, and comprise connecting plate, described connecting plate is fixed with sleeve, and the bottom end opening of described sleeve, barrel is arranged with screwed hole, and in screwed hole, rotation is connected with fastening bolt; Described sleeve is equipped with the toothholder for pick setting of several different sizes, before this device changes, pick fixture pick directly and the connected mode of sleeve weld, add toothholder, the stability of structure can be increased like this, strengthen the intensity connected, the ability of whole pick grip device bearing strength is increased, larger ess-strain can be born; In use, only need to change the toothholder of different geometrical size, the installation of different pick can be met, simple and reliable for structure, easy for installation, applicability is strong.
Description
Technical field
The utility model belongs to the technical field of coal petrography cutting test, is specifically related to a kind of pick grip device of monodentate coal petrography cutting test.
Background technology
In the process of monodentate coal petrography cutting test, the reciprocal platform of coal petrography cutting test device is moved in the horizontal direction by the driving of hydraulic cylinder, and the mutual extruding of coal petrography and pick, shear action complete the cut to coal petrography.In the process of laboratory condition simulation coal petrography cutting test, need the pick changing various geometric, to evaluate the pick of various geometric to the impact of coal petrography Cutting Performance.The structure of pick fixture before used mainly comprises: pick, sleeve and connection are dull and stereotyped.One end of pick and sleeve adopts the mode of welding to link together, and the other end of sleeve is together with connection plate welding.If the pick for each geometric parameter all does a kind of grip device adapted with it, the cost of process-cycle and test will be increased, also can cause a large amount of wastes simultaneously, therefore need to develop a kind of fixture tried out in various geometric pick.
Utility model content
The purpose of this utility model is to provide a kind of pick grip device of monodentate coal petrography cutting test, before change, pick fixture pick directly and the connected mode of sleeve weld, add toothholder, the stability of structure can be increased like this, strengthen the intensity connected, the ability of whole pick grip device bearing strength is increased, larger ess-strain can be born; In use, only need to change the toothholder of different geometrical size, the installation of different pick can be met, simple and reliable for structure, easy for installation, applicability is strong.
The utility model adopts following technical scheme to realize: a kind of pick grip device of monodentate coal petrography cutting test, comprise connecting plate, described connecting plate is fixed with sleeve, the bottom end opening of described sleeve, barrel is arranged with screwed hole, and in screwed hole, rotation is connected with fastening bolt; Described sleeve is equipped with the toothholder for pick setting of several different sizes.
The center of described toothholder is provided with the through hole for pick setting.
The longitudinal section of described toothholder is T-shaped, and its comparatively thin place is main base frame, and its comparatively thick place is spacing pedestal, and the external diameter of described main base frame is less than sleeve diameter, and the external diameter of spacing pedestal is not less than sleeve outer diameter.
Described pick comprises tooth body and connecting axle, and described connecting axle is installed in through hole, and is provided with jump ring in axis body end, prevents moving axially of pick.
The inner end of described fastening bolt is provided with flexible non-slip mat.
Described sleeve welds with connecting plate.
Described connecting plate is provided with installing hole.
The beneficial effects of the utility model are: a kind of pick grip device of monodentate coal petrography cutting test, before changing, pick fixture pick directly and the connected mode of sleeve weld, add toothholder, the stability of structure can be increased like this, strengthen the intensity connected, the ability of whole pick grip device bearing strength is increased, larger ess-strain can be born; In use, only need to change the toothholder of different geometrical size, the installation of different pick can be met, simple and reliable for structure, easy for installation, applicability is strong.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is a kind of overall structure schematic diagram of pick grip device of monodentate coal petrography cutting test
In figure, 1. pick, 2. toothholder, 3. connecting plate, 4. sleeve, 5. fastening bolt, 6. jump ring.
Detailed description of the invention
In the accompanying drawings, a kind of pick grip device of monodentate coal petrography cutting test, comprises connecting plate 3, and described connecting plate 3 is fixed with sleeve 4, and the bottom end opening of described sleeve 4, barrel is arranged with screwed hole, and in screwed hole, rotation is connected with fastening bolt 5; Described sleeve 4 is equipped with the toothholder 2 for pick setting 1 of several different sizes.
The center of described toothholder 2 is provided with the through hole for pick setting 1.
The longitudinal section of described toothholder 2 is T-shaped, and its comparatively thin place is main base frame, and its comparatively thick place is spacing pedestal, and the external diameter of described main base frame is less than sleeve 4 internal diameter, and the external diameter of spacing pedestal is not less than sleeve 4 external diameter.
Described pick 1 comprises tooth body and connecting axle, and described connecting axle is installed in through hole, and is provided with jump ring 6 in axis body end, prevents moving axially of pick 1.
The inner end of described fastening bolt 5 is provided with flexible non-slip mat.
Described sleeve 4 welds with connecting plate 3.
Described connecting plate 3 is provided with installing hole.
During use, first pick 1 is installed on toothholder 2, then toothholder 2 is inserted in sleeve 4, regulate fastening bolt 5, make it clamp toothholder 2, realize the installation of toothholder 2 and sleeve 4.In using, only need to change the toothholder 2 of different geometrical size, the installation of different pick 1 can be met, simple and reliable for structure, easy for installation, applicability is strong.
