Abstract
The utility model discloses a chain cutting device which comprises a base and a screw. The screw is inserted into the base by a screw thread; the screw is provided with a plurality of through holes vertical to the axis of the screw; the positions and the number of the through holes are set according to the width of a chain; pin rods are arranged for being matched with the through holes; and the length of each pin rod is greater than the diameter of the screw. According to the utility model, by forming a plurality of through holes, the moving distance of a chain cutting device ejector rod is limited at different positions by the pin rods, the extrusion position of a chain pin of the chain is guaranteed not to influence the perpendicularity of the chain pin in the process of pressing again due to the excessively outward extrusion position or fall-off, and meanwhile, intensity and the lubricating degree of the chain are also guaranteed not to be influenced due to the excessively large pressing depth or the excessively small pressing depth when the chain pin is pressed in.
Description
Technical field
The utility model relates to a kind of cutter chain device, belongs to field of tool.
Background technology
Traditional cutter chain device is extruded the pin between chain link to realize cutter chain by push rod, but traditional cutter chain device tends to, push rod was clamp-oned dark and was made chain pin be ejected chain link, cause chain to disintegrate, and chain pin is ejected very difficult again by vertical pushing back, even if push back the lubricity that also can affect chain afterwards.
Utility model content
The purpose of this utility model is: a kind of technical scheme that can address the above problem is provided.
The utility model is realized by the following method:
A kind of cutter chain device, comprise base, screw rod, described screw rod penetrates in base by screw thread, on described screw rod, be provided with some through holes perpendicular to screw axis, the position of described through hole and quantity arrange according to chain width, with the supporting pin rod that is provided with of described through hole, the length of described pin rod is greater than the diameter of screw rod.
As further innovation of the present utility model, described pin rod is variable-diameter structure, take pin rod axially middle part be benchmark, pin rod wherein half is flaring structure, the diameter of described flaring structure end face is greater than the diameter of through hole.
As further innovation of the present utility model, described cutter chain device also comprises chain pin push rod, described chain pin push rod is arranged on the axis centre of screw rod, for pushing the pin of chain, it is characterized in that: described chain pin push rod is flexibly connected with screw rod by coil spring, and the length of described coil spring is less than 1/4th of through-hole spacing.
As further innovation of the present utility model, described screw rod is magnesium alloy material.
beneficial effect
1. thereby the utility model carries out spacing by pin rod to the displacement of cutter chain device push rod at diverse location by several through holes are set, what the chain pin that has guaranteed chain was extruded position can be because of too not outer or drop and affect the perpendicularity of chain pin while again pressing, and guaranteed that chain pin is pressed into Shi Buhui because cross dark or cross shallow and affect intensity and the lubricity of chain simultaneously yet.
2. the utility model makes chain between cutter chain by spring is set, and links is crossed push rod and is fixed on cutter chain device.
3. the slight and light weight of screw rod has been demonstrate,proved in magnesium alloy material quality guarantee, and magnesium alloy also has good machining property simultaneously, facilitates the more accurate limiting through hole of turning.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of cutter chain device.
Fig. 2 is the schematic diagram of pin rod.
In figure: 1, screw rod; 2, through hole; 3, base; 4, push rod; 5, coil spring.
The specific embodiment
Below in conjunction with accompanying drawing, be described further:
As shown in Figure 1, this cutter chain device comprises base 3, screw rod 1, push rod 4, described screw rod 1 penetrates in base 3 by screw thread, is provided with some through holes 2 perpendicular to screw rod 1 axis on described screw rod 1, and the position of described through hole 2 and quantity arrange according to chain width, with the supporting reducing pin rod that is provided with of described through hole as Fig. 2, the length of described pin rod is greater than the diameter of screw rod, described chain pin top, and 4 are flexibly connected with screw rod 1 by coil spring 5.
In use, according to the compression travel of the size of chain and push rod, select suitable position pin rod to be inserted in the through hole 2 of screw rod 1, rotation cutter chain device screw rod, when chain pin is extruded into precalculated position, pin rod plays position-limiting action, now pulls down link, vertical being pressed in link in the time of can facilitating like this chain pin to connect again, the smoothness of assurance chain.
Claims (4)
