Description
technical field:
The utility model belongs to construction machinery production field, relates in particular to a kind of novel pin pulling out device.
background technology:
Along with the development of engineering machinery, between parts, by axle, connect more and more generally, the fit system in axle and hole is gapped to be coordinated, three kinds of interference fit, interference fits, can meet the needs that each position connects.But some problems have also been there are, dismounting such as axle, at some assembling arms as large in crane and panoramic table, be linked and packed, the diameter of the axle using is larger, length is also long, caused very large difficulty to workman's dismounting, therefore a kind of novel pin pulling out device is provided, structure is simpler, economic and practical, be easy to exchange.
summary of the invention:
The purpose of this utility model is to overcome the problem in existing assembling process and a kind of novel pin pulling out device is provided.
It is to implement like this that the utility model solves the technical scheme that its technical problem adopts: a kind of novel pin pulling out device, comprise the bolt of pulling pin, sliding bar, baffle plate, weight, fastening baffle plate bolt, spring washer, it is characterized in that: the fastening baffle plate bolt fixed dam of one end of sliding bar with spring washer, weight is enclosed within on sliding bar, the other end of the sliding bar bolt of fixedly pulling pin, is connected with bearing pin.
Described sliding bar is smooth screw rod, and there is the internal thread hole corresponding with the bolt of pulling pin on bearing pin top.
The utlity model has the advantage that structure is simpler, economic and practical, be easy to exchange.
accompanying drawing explanation:
The front view that accompanying drawing 1 is installed for the utility model structure;
In figure: 1. bearing pin, 2. pull pin bolt, 3. sliding bar, 4. weight, 5. baffle plate, 6. spring washer, 7. fastening baffle plate bolt.
the specific embodiment:
As shown in the figure, a kind of novel pin pulling out device, comprises the bolt 2 of pulling pin, sliding bar 3, weight 4, baffle plate 5, spring washer 6, fastening baffle plate bolt 7, it is characterized in that:
Fastening baffle plate bolt 7 fixed dams 5 of one end of sliding bar 3 with spring washer 6, weight 4 is enclosed within on sliding bar 3, and the other end of sliding bar 3 bolt 2 of fixedly pulling pin, is connected with bearing pin 1.
Described sliding bar 3 is smooth screw rod, and bearing pin 1 top has and the corresponding internal thread hole of bolt 2 of pulling pin.
Embodiment: first use the fastening baffle plate bolt 7 with spring washer 6 baffle plate 5 to be fixed on to the right-hand member of sliding bar 3, weight 4 is penetrated from left end, the bolt 2 of pulling pin is welded to the left end of sliding bar 3, then integral body is connected with bearing pin 1 through the bolt 2 of pulling pin,
Weight 4 slides on sliding bar 3, it is just can not slide after weight 4 slides into baffle plate 5 that baffle plate 5 plays position-limiting action at the right-hand member of sliding bar 3 again, utilize weight 4 and the percussion of baffle plate 5 to realize extracting of bearing pin 1, this power is very large, because weight 4 kinetic energy when sliding is very large, the quality of weight 4 is larger, and bearing pin 1 is easily extracted.This structure is very simple, and it is very convenient to operate, simple and practical.
