Abstract
The utility model relates to a thick positioning pin structure and belongs to the technical field of vertical type knife rests. The thick positioning pin structure solves a problem that a reverse leaning pin of the existing positioning pin structure is easy to break after being struck, blocking phenomena take place frequently, strength is not high due to the fact that a clutch pin and the reverse leaning pin need to be matched for use, and the diameter is small. The thick positioning pin structure comprises a clutch disc and a reverse leaning disc, wherein a pinch roller is arranged between the clutch disc and the reverse leaning disc, and the positioning pin structure is arranged in the pinch roller. The positioning pin structure comprises a thick positioning pin and a spring, wherein the spring is sleeved on the thick positioning pin. The diameter of the lower end (stress end) of the pin thickens, so that strength is improved. Original three-part constitution is changed into single-part constitution, the thick positioning pin structure is simple in manufacture and convenient to install, the reduction is reduced, the failure rate is greatly reduced, and blocking phenomena are fewer.
Description
Technical field
The utility model belongs to the vertical tool holder technical field, refers in particular to a kind of coarse positioning pin structure.
Background technique
Locating pin structure is the indispensable part of cutter tower, existing locating pin structure instead forms by pin and spring usually by on-of pin, instead play the guiding role by on the pin pin being housed, defective is clearly arranged like this: instead easily fracture by the pin bump is stressed, stuck phenomenon takes place frequently; On-of pin leans on pin owing to need to be used in conjunction with anti-in addition, and diameter is little, causes intensity not high.
Summary of the invention
For the deficiency that exists in the background technique, the purpose of this utility model is to provide a kind of locating pin structure of low fault.
For achieving the above object, the utility model provides following technological scheme: the coarse positioning pin structure, and comprise clutch wheel and instead by dish, be provided with pinch roller in clutch wheel with between instead by dish, it is characterized in that: in pinch roller, be provided with locating pin structure.
Above-mentioned locating pin structure comprises coarse positioning pin and spring, and spring housing is contained on the coarse positioning pin.
Above-mentioned coarse positioning pin lower end diameter is greater than its upper end diameter.
Above-mentioned spring housing is contained in the upper end of coarse positioning pin, and the diameter of spring is less than coarse positioning pin lower end diameter.
Axial and the clutch wheel of above-mentioned coarse positioning pin, anti-by coiling into vertical arrangement.
The utility model beneficial effect compared to existing technology is:
1. the utility model pin is owing to lower end (force side) diameter overstriking, and intensity improves;
2. the utility model is comprised of three original parts and changes single component into, make simple, easy for installation, cost reduction;
3. the utility model rate of fault reduces greatly, and stuck phenomenon is few.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Number in the figure implication: 1-clutch wheel; 2-coarse positioning pin; The 3-spring; The 4-pinch roller; 5-is instead by dish.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the coarse positioning pin structure comprises clutch wheel 1 and instead by dish 5, is provided with pinch roller 4 in clutch wheel 1 with between instead by dish 5, it is characterized in that: be provided with locating pin structure in pinch roller 4.
Above-mentioned locating pin structure comprises coarse positioning pin 2 and spring 3, and spring 3 is sleeved on the coarse positioning pin 2.
Above-mentioned coarse positioning pin 2 lower end diameter are greater than its upper end diameter.
Above-mentioned spring 3 is sleeved on the upper end of coarse positioning pin 2, and the diameter of spring 3 is less than coarse positioning pin 2 lower end diameter.
Axial and the clutch wheel 1 of above-mentioned coarse positioning pin 2, anti-by 5 one-tenth vertical arrangements of dish.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these of above-mentioned hypothesis improve and modification also should be considered as protection domain of the present utility model.
