Abstract
A kind of press crankshaft support sleeve mounting structure convenient for assembly, including crankshaft, support sleeve and fuselage, copper sheathing is equipped between crankshaft and support sleeve, support sleeve is mounted in fuselage hole, support sleeve and fuselage are connected by bolt, the upper semi-circle of the support sleeve is bonded setting with fuselage hole, gap is equipped between the lower half circle and fuselage hole of support sleeve, the lower half circle bottom of support sleeve is equipped with wedge key slot, taper key is equipped in wedge key slot, the bottom of taper key is bonded setting with fuselage hole, it is bolted between the gib head and fuselage end face of taper key, it had both been compensated for because being difficult to the problem of putting into caused by gap is too small or a little interference, solve again because gap it is excessive caused by pulsatile impact power bring frame deflection, structure is simple, it is convenient for disassembly and assembly, it is reliable and stable.
Description
Technical field:
The utility model relates to a kind of press crankshaft support sleeve mounting structures convenient for assembly.
Background technique:
Currently, the assembly of most of Curved shaft support set and fuselage uses transition fit as shown in Figure 1, support sleeve in the market
Gap between fuselage is too small or has a little interference, assembly when be difficult smoothly to be loaded into, even if be loaded into overhaul when
It waits and is difficult to remove again；If gap is excessive, when in use, since pulsatile impact power is born in fuselage hole, fuselage hole occurs quickly
Deformation, influences the using effect of entire lathe, it cannot be guaranteed that the stability that complete machine is used for a long time, causes crankshaft branch under serious conditions
Support set and fuselage hole are stuck, can not dismantle, and are not able to satisfy the requirement of Curved shaft support set.
Utility model content:
The purpose of this utility model is exactly in order to make up for the deficiencies of the prior art, to provide a kind of press machine convenient for assembly
Curved shaft support covers mounting structure, it had not only been compensated for because being difficult to the problem of putting into, but also solution caused by gap is too small or a little interference
Because gap it is excessive caused by pulsatile impact power bring frame deflection, it is simple in construction, easy to disassemble and assemble, it is reliable and stable, solve
The problems of the prior art.
Used technical solution is the utility model to solve above-mentioned technical problem:
A kind of press crankshaft support sleeve mounting structure convenient for assembly, including crankshaft, support sleeve and fuselage, in crankshaft and
Copper sheathing is equipped between support sleeve, support sleeve is mounted in fuselage hole, and support sleeve and fuselage are connected by bolt, the support sleeve
Upper semi-circle is bonded setting with fuselage hole, and gap, the lower half circle bottom of support sleeve are equipped between the lower half circle and fuselage hole of support sleeve
Equipped with wedge key slot, taper key is equipped in wedge key slot, the bottom of taper key is bonded setting, the hook of taper key with fuselage hole
It is bolted between head and fuselage end face.
The taper key upper surface is equipped with the gradient of 1:100.
The utility model is installed using support sleeve upper semi-circle and fuselage using transition fit, and support sleeve lower half circle is adopted with fuselage
It is installed with clearance fit, has adapted to the non-stress situation of support sleeve top half stress condition and lower half portion, solved because between
Be difficult to the problem of putting into caused by gap is too small or a little interference, taper key solve again simultaneously because gap it is excessive caused by pulsation
Impact force bring frame deflection, its structure is simple, and convenient disassembly is reliable and stable, greatly improves disassembly efficiency.
Detailed description of the invention:
Fig. 1 is to improve front crankshaft support sleeve main view.
Fig. 2 is that Curved shaft support covers main view after improving.
In figure, 1, crankshaft, 2, support sleeve, 3, fuselage, 4, wedge key, 5, copper sheathing, 6, wedge key slot.
Specific embodiment:
The utility model is described further with embodiment with reference to the accompanying drawing:
As shown in Fig. 2, a kind of press crankshaft support sleeve mounting structure convenient for assembly, including crankshaft 1,2 and of support sleeve
Fuselage 3 is equipped with copper sheathing 5 between crankshaft 1 and support sleeve 2, and support sleeve 2 is mounted in fuselage hole, and support sleeve 2 passes through with fuselage 3
Bolt is connected, and the upper semi-circle of the support sleeve 2 is bonded setting with fuselage hole, is equipped between the lower half circle and fuselage hole of support sleeve 2
The lower half circle bottom in gap, support sleeve 2 is equipped with wedge key slot 6, and taper key 4, the bottom of taper key 4 are equipped in wedge key slot 6
It is bonded setting with fuselage hole, is bolted between 3 end face of gib head and fuselage of taper key 4.
4 upper surface of taper key is equipped with the gradient of 1:100, and when taper key 4 is squeezed into fuselage 3, surface is generated very
Big pretightning force, when work, main frictionally transmitted torque, and can bear unidirectional axial force.
When installation, support sleeve 2 is packed into fuselage hole, then taper key 4 is squeezed into wedge key slot 6, tightens bolt, together
When tighten support sleeve 2 and the bolt between fuselage 3.
When disassembly, the bolt between taper key 4 and fuselage 3 is unloaded, taper key 4 is taken out, then unloads support sleeve 2
With the bolt between fuselage 3, support sleeve 2 is taken out.
The utility model is installed using 2 upper semi-circle of support sleeve and fuselage 3 using transition fit, 2 lower half circle of support sleeve and machine
Body 3 is gap-matched installation, has adapted to the non-stress situation of support sleeve 2 top half stress condition and lower half portion, solves
Because being difficult to the problem of putting into caused by gap is too small or a little interference, taper key solves again cause because gap is excessive simultaneously
Pulsatile impact power bring frame deflection, its structure is simple, and convenient disassembly is reliable and stable, greatly improves disassembly efficiency.
Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
It protects in range.
Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
