Description
Technical field
The utility model relates to the manufacture field of mechanical part more particularly to a kind of crosshead guides.
Background technique
Sliding block is in machinery field using extremely wide, but sliding block is when in use, and it is the prior art that sliding trace, which is difficult to control,
Present in difficult point.
Utility model content
The utility model is in view of the above problems, provide a kind of delicate structure, guiding is stablized, good working effect and is processed into
This lower crosshead guide.
The technical solution of the utility model is: including hollow cylinder one, hollow cylinder two and a pair of projections, the hollow cylinder one is solid
Surely it is connected to the top of hollow cylinder two, the hollow cylinder one and hollow cylinder two are concentric, and the inner edge diameter of the hollow cylinder one is big
In the inner edge diameter of hollow cylinder two, the external profile diameter of the hollow cylinder one is less than the external profile diameter of hollow cylinder two, a pair of described convex
Platform is fixedly connected on the lateral wall of hollow cylinder two, and the boss is plate, and the middle part of a pair of boss offers through-hole
One, the hollow cylinder two radially offers through-hole two, and the through-hole one is equal with the aperture of through-hole two, the through-hole one with it is logical
Hole two is concentric.
Several slots are provided in the axial direction on the inner wall of the hollow cylinder two.
The section of several slots is semicircle.
The section of several slots is trapezoidal.
The notch of several slots is removably connected with strainer.
When the utility model is specifically used, any boss is placed in required limit track, it will be in hollow cylinder two
Required limit shaft is worn, such crosshead guide can be transported under the position-limiting action of boss and hollow cylinder two with stable track
It is dynamic, at this point, securing the workpiece against the boss of the other side, there can be more stable running track by crosshead guide.It is whole
It is upper to have the advantages that stable delicate structure, guiding, good working effect and processing cost are lower.

Specific embodiment
The utility model as shown in figures 1 to 6, including hollow cylinder 1, hollow cylinder 22 and a pair of projections 3, the hollow cylinder one
1 is fixedly connected on the top of hollow cylinder 22, and the hollow cylinder 1 and hollow cylinder 22 are concentric, the inner edge of the hollow cylinder 1
Diameter is greater than the inner edge diameter of hollow cylinder 22, and the external profile diameter of the hollow cylinder 1 is less than the external profile diameter of hollow cylinder 22, and one
The boss 3 is fixedly connected on the lateral wall of hollow cylinder 22, the boss 3 is plate, the middle part of a pair of boss 3
Through-hole 1 is offered, the hollow cylinder 22 radially offers through-hole 2 20, the hole of the through-hole 1 and through-hole 2 20
Diameter is equal, and the through-hole 1 and through-hole 2 20 are concentric.When specifically used, any boss is placed in required position-limited rail
In road, required limit shaft will be worn in hollow cylinder two, such crosshead guide can be made in the limit of boss and hollow cylinder two
It is moved under with stable track, at this point, securing the workpiece against the boss of the other side, can be had by crosshead guide relatively steady
Fixed running track.Have the advantages that stable delicate structure, guiding, good working effect and processing cost are lower on the whole.
Several slots are provided in the axial direction on the inner wall of the hollow cylinder two.In this way, when passing through required limit in hollow cylinder two
When the axis of position, both can by reducing contact area to reduce friction loss, can also to the air flowing in hollow cylinder two there are
Gap improves the working effect of this case so that resistance caused by air is smaller when limit shaft passes through hollow cylinder two；In addition,
Also reduce materials'use to a certain extent, reduce material cost.
The section of several slots is semicircle.Semicircular slot is easy to process, easy to process, passes through when in hollow cylinder two
It, both can be by reducing contact area to reduce friction loss when required limit shaft, it can also be to the air in hollow cylinder two
There are gaps for flowing, so that resistance caused by air is smaller when limit shaft passes through hollow cylinder two, improve the work effect of this case
Fruit；In addition, also reducing materials'use to a certain extent, reduce material cost.
The section of several slots is trapezoidal.Trapezoidal slot can provide limit shaft higher support, and extraction does not promote this
The stability of case can both reduce friction damage when passing through required limit shaft in hollow cylinder two by reducing contact area
Consumption, the air in hollow cylinder two can also be given to flow, and there are gaps, so that when limit shaft passes through hollow cylinder two, caused by air
Resistance is smaller, improves the working effect of this case；In addition, also reducing materials'use to a certain extent, reduce material cost.
The notch of several slots is removably connected with strainer.In this way, the sundries in air can be effectively prevent to enter
Crosshead guide, improves the service life of this case, and improves the stability of this case and the frequency of required cleaning.
