Description
Technical field
The utility model relates to guide wheel for excavator field, refers more particularly to a kind of from the little convex guide wheel of centering.
Background technology
Guide wheel is as the important component part of digging machine walking mechanism, and it is directly connected to serviceability and the walking performance of excavating machine, and the support on traditional guide wheel both sides generally all adopts spring pin location, and between guide wheel and tightening device, the general screw that adopts is installed; Both sides support all adopts spring pin to locate, for dead positional flexibility is poor, its in boring procedure normally two supports manufacture together with axle, require high to drilling operation, the phenomenon that scrapping appears in pair of brackets and axle often easily occurs because location hole drill is wrong, and this adds the one-tenth manufacturing cost of product undoubtedly; Guide wheel and tightening device adopt screw to install, and this design manufacturing cost in production in enormous quantities is high, operation is numerous and diverse, production efficiency is low, and comparatively bothers in installation process.
Summary of the invention
The purpose of this utility model be to overcome above-mentioned weak point of the prior art and provide a kind of structure simple, cost-saving, practical from the little convex guide wheel of centering.
The utility model realizes in the following way:
A kind of from the little convex guide wheel of centering, it is characterized in that: comprise wheel body 1, axle 2, the middle part of described axle 2 is connected on wheel body 1 by copper sheathing 3; The two ends up and down of described wheel body 1 are respectively equipped with float grease seal 4 and lower float grease seal 5; The upper end of described axle 2 is provided with jump-ring slot 21; The lower end of described axle 2 is provided with dowel hole 22; Spring pin is provided with in described dowel hole 22; The upper end of described axle 2 is connected with upper bracket 6; Described upper bracket 6 is through jump-ring slot 21, and jump-ring slot 21 is provided with jump ring 7; Described upper bracket 6 can 360 degree of rotations relative to wheel body 1; The bottom of described upper bracket 6 is provided with upper bracket float grease seal 8; Described upper bracket float grease seal 8 is positioned at directly over float grease seal 4; The lower end of described axle 2 is connected with lower bracket 9; The inwall of described lower bracket 9 is connected with the spring pin in dowel hole 22; The upper surface of described lower bracket 9 is provided with lower bracket float grease seal 10; Described lower bracket float grease seal 10 is positioned at immediately below lower float grease seal 5; The right-hand member of described upper bracket 6 and lower bracket 9 is respectively equipped with a self-align cylinder boss 11.
The beneficial effects of the utility model are: lower bracket adopts spring pin location, and upper bracket adopts jump ring location; Lower bracket is fixed, and upper bracket can rotate around axle, and what can well solve product scraps problem, can avoid in the course of processing because the hole position error of locating dowel pin causes the phenomenon such as asymmetric, not parallel of upper bracket and lower bracket by actv. simultaneously; Can make whole guide wheel automatic capturing center in the process of moving, centering is good simultaneously; Adopt the mounting design of cylindrical location convex between guide wheel and tightening device, eliminate the trouble of boring screw hole and installing screw; Realize Fast Installation, can save production cost by actv. in production in enormous quantities.
Accompanying drawing explanation
Fig. 1 the utility model structural representation.
Detailed description of the invention
Now by reference to the accompanying drawings, the utility model detailed description of the invention is described in detail in detail:
As shown in Figure 1, a kind of from the little convex guide wheel of centering, comprise wheel body 1, axle 2, the middle part of axle 2 is connected on wheel body 1 by copper sheathing 3; The two ends up and down of wheel body 1 are respectively equipped with float grease seal 4 and lower float grease seal 5; The upper end of axle 2 is provided with jump-ring slot 21; The lower end of axle 2 is provided with dowel hole 22; Spring pin is provided with in dowel hole 22; The upper end of axle 2 is connected with upper bracket 6; Upper bracket 6 is through jump-ring slot 21, and jump-ring slot 21 is provided with jump ring 7; Upper bracket 6 endoporus and axle 2 are free-running fit, and upper bracket 6 can 360 degree of rotations relative to wheel body 1, thus reach upper bracket 6 position and lower bracket 9 positional symmetry; The bottom of upper bracket 6 is provided with upper bracket float grease seal 8; Upper bracket float grease seal 8 is positioned at directly over float grease seal 4; The lower end of axle 2 is connected with lower bracket 9; The inwall of lower bracket 9 is connected with the spring pin in dowel hole 22; The upper surface of lower bracket 9 is provided with lower bracket float grease seal 10; Lower bracket float grease seal 10 is positioned at immediately below lower float grease seal 5; The right-hand member of upper bracket 6 and lower bracket 9 is respectively equipped with a self-align cylinder boss 11, is used for replacing screw to be connected with tightening device.
The utility model lower bracket 9 adopts spring pin to locate, and upper bracket 6 adopts jump ring 7 to locate; Lower bracket 9 is fixed, and upper bracket 6 can rotate around axle 2, and what can well solve product scraps problem, can avoid in the course of processing because the error of dowel hole 22 causes the phenomenon such as asymmetric, not parallel of upper bracket 6 and lower bracket 9 by actv. simultaneously; Can make whole guide wheel automatic capturing center in the process of moving, centering is good simultaneously; Adopt the mounting design of self-align cylinder boss 11 between guide wheel and tightening device, eliminate the trouble of boring screw hole and installing screw; Realize Fast Installation, can save production cost by actv. in production in enormous quantities.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
