Pin body, resilient sleeve, guide and clamp nut, the stage casing both sides of the pin body are followed successively by conical section and screw thread respectively
Section, the resilient sleeve inner ring be the taper that match with the pin body conical section and resilient sleeve vertically in jacket wall fluting,
Resilient sleeve one end jacket wall outer rim is provided with raised step, and the resilient sleeve is inserted in the conical section and projection of the pin body
Step is located at the thread segment of the pin body, and the guide is inserted in the outer ring of the resilient sleeve and against the raised platform
Rank, the clamp nut is twisted the thread segment in the pin body and fastens the resilient sleeve.
Further, the oscillating bearing interference fits of the stage casing of the pin body and mill type cylinder.
Further, the resilient sleeve coordinates with guide gap.
Because the utility model employs above-mentioned technical proposal for the pin shaft structure that mill type cylinder is connected with mechanical mechanism,
I.e. this structure includes pin body, resilient sleeve, guide and clamp nut, and the stage casing both sides of pin body are followed successively by conical section respectively
And thread segment, resilient sleeve inner ring is the taper and resilient sleeve matched with pin body conical section vertically in jacket wall fluting, bullet
Property cover one end jacket wall outer rim and be provided with raised step, the conical section and raised step that resilient sleeve is inserted in pin body are located at bearing pin sheet
The thread segment of body, guide is inserted in the outer ring of resilient sleeve and against raised step, and clamp nut twists the thread segment in pin body
And fasten resilient sleeve.This structure overcomes the defect of traditional oil cylinder bearing pin connected mode, by changing bearing pin type of attachment, solution
The problem that certainly mill type cylinder bearing pin cannot be dismantled, improves maintenance of equipment efficiency, reduces labour intensity and cost.
Brief description of the drawings
The utility model is described in further detail with implementation method below in conjunction with the accompanying drawings：
Fig. 1 is that the utility model is used for the pin shaft structure schematic diagram that mill type cylinder is connected with mechanical mechanism；
Fig. 2 is resilient sleeve schematic diagram in this structure；
Fig. 3 is guide schematic diagram in this structure.
Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, the utility model is used for the bearing pin knot that mill type cylinder is connected with mechanical mechanism to embodiment
Structure includes pin body 1, resilient sleeve 2, guide 3 and clamp nut 4, and the both sides of stage casing 11 of the pin body 1 are followed successively by respectively
Conical section 12 and thread segment 13, the inner ring of the resilient sleeve 2 are the taper and elasticity matched with the pin body conical section 12
Set 2 is slotted in jacket wall vertically, and one end jacket wall outer rim of the resilient sleeve 2 is provided with raised step 21, and the resilient sleeve 2 is inserted in described
The conical section 12 and raised step 21 of pin body 1 are located at the thread segment 13 of the pin body 1, and the guide 3 is inserted in institute
State the outer ring of resilient sleeve 2 and against the raised step 21, the clamp nut 4 is twisted in the thread segment of the pin body 1
13 and fasten the resilient sleeve 2.
Preferably, the oscillating bearing interference fits of the stage casing 11 of the pin body 1 and mill type cylinder.
Preferably, the resilient sleeve 2 coordinates with the gap of guide 3.
Pin body in this structure is processed using round steel on lathe, two ends processing it is tapered, taper according to answer
Depending on load stress size, the conical surface must assure that certain finish, tapered outer ends processing screw thread, for being screwed into fastening spiral shell
The size of the adaptation various oscillating bearing interference fits of oil cylinder is processed into mother, stage casing, must be carried out at surface heat after Surface Machining is good
Reason, the mechanical strength on enhancing pin body surface.Resilient sleeve is processed into and pin using the preferably quenched material processing of rigidity, external diameter
Set internal diameter gap fit dimension, one end outer rim processing raised step is fit into the position of pin-and-hole for spacing and prediction resilient sleeve
Shifting amount, resilient sleeve inner ring processing is tapered, and taper is sized to fit into the taper size of pin body, and inner conical surface also must assure that tool
There is certain finish, height dimension is slightly less than guide highly, and axially opens a groove in resilient sleeve, plays dilating effect.
When being assembled using this structure, first oil cylinder is placed in the bore at mechanical mechanism two ends, and substantially keep with
Bore axis is consistent, then after oscillating bearing endoporus is heated into 200~350C °, pin body is loaded in oscillating bearing, then
Resilient sleeve is installed on the conical section of pin body in company with guide, resilient sleeve is tapped with hand hammer, it is ensured that have necessarily with pin body
Pretightning force, then screw on the clamp nut of pin body thread segment, Tightening moment receives range according to parts size and bearing load
Depending on degree, complete mill type cylinder and installed with the connection of mechanical mechanism.
When maintenance of equipment need to be dismantled, first the clamp nut at pin body two ends is removed, release the locking shape of resilient sleeve
State, due to resilient sleeve under without coupling mechanism force still with the presence of larger pretightning force, therefore bearing pin is tapped using adz-eye hammer back and forth
The two ends of body, are shaken loose resilient sleeve with lash method is tapped, and are ejected resilient sleeve using the taper surface of pin body conical section, by
It is interference fits in the oscillating bearing in pin body stage casing and oil cylinder, can continues to tap bearing pin after resilient sleeve is taken out
, until taking out pin body from oscillating bearing, thus with mechanical mechanism can be completely separated mill type cylinder by body, complete
Dismounting operation.
This structure is applied to the hydraulic jack of chassis hoisting system, is needed without generation in multiple dismounting oil cylinder bearing pin
Get angry the phenomenon of cutting, substantially increase overhaul efficiency, direct economic benefit shows that this structure has up to 500,000 yuan/year
Obvious technical advantage.
Can be put into sizable reduction labour using this structure, shorten the repair time, it is ensured that vehicle normally maintains inspection
Repair, reduce maintenance and spare parts cost, substantially increase overhaul efficiency.
