Abstract
The utility model relates to a guide rail counter bore cover which comprises a circular plate body and a guide skirt which extends to one side along with the edge of the circular plate body, wherein the outer edge of the tail end of the guide skirt is provided with a chamfer; a plurality of skirt notches are distributed on the guide skirt; a through hole positioned inside the guide skirt is formed in the circular plate body; and an annular chamfer is formed on one side of the circular plate body, which is close to the guide skirt. Due to interference fit and guide angle, the assembly process can be convenient. The cover is opened by the compressed air, and the counter bore cover can be easily detached and is hardly damaged. The counter bore cover has the design of the skirt notches, so that the guide skirt has good plasticity, the dimension error in the process of machining the counter bore is made up, and the counter bore cover is conveniently assembled. The upper edge of the counter bore cover is based on the chamfer design, so that the chamfer on the counter bore can be effectively filled and sealed, the adaptability of the counter bore chamfer is high, and the sealing effect is enhanced.
Description
Technical field
The utility model relates to a kind of guide rail counterbore lid, and this counterbore lid adopts plastics manufacturing, and is easy for installation, can solve the sealing problem of rolling linear guide counterbore and can repeatedly use.
Background technique
The effect of guide rail counterbore lid is the counterbore on the sealing guide rail.The counterbore that uses at existing guide rail counterbore covers as simply cylindrical, and material is plastics or brass.
Because it is simple in structure, for so that counterbore covers the excellent sealing effect to counterbore, very high to the matching requirements of guide rail counterbore and counterbore lid.Requiring the counterbore lid at assembly technology must be the interference drive fit with counterbore.Therefore need in the assembly process counterbore lid is knocked and pushes, until the counterbore lid is in place with counterbore.In this assembly process, because covering, knocked counterbore, if the improper damage that very easily causes the counterbore lid of method.
After said process was finished, because the interference drive fit, the counterbore lid was combined closely easily opening with counterbore.If in use need opening, must knock destruction counterbore lid and could take out.The destroyed of counterbore lid can't again install, use this moment.Thereby this counterbore lid can only be disposable use and cause a large amount of wastes.
The model utility content
The technical problems to be solved in the utility model provides all easier, not fragile and guide rail counterbore lids that can repeatedly use of a kind of assembling and dismounting.
For solving the problems of the technologies described above, the utility model provides a kind of guide rail counterbore lid, it comprises: circular plate body, along the edge of this circle plate body to the extended guiding of side shirt rim 1, the terminal outward edge of this guiding shirt rim 1 is provided with chamfering, guiding is distributed with a plurality of shirt rims otch 2 on the shirt rim 1, circular plate body is provided with the through hole 4 that is in the described guiding shirt rim 1, and a side of contiguous described guiding shirt rim 1 is provided with annular chamfer 3 on the circular plate body.
With respect to prior art, the technique effect that the application has: adopt interference fit and angle of deflection, can make assembly process more convenient.Adopt pressurized air to carry out opening, can make the simpler and not fragile counterbore lid of dismounting counterbore lid.
Counterbore lid of the present utility model adopts the design of shirt rim otch, makes the guiding shirt rim have more plasticity, adds the size error in man-hour to remedy counterbore, makes things convenient for the assembling of counterbore lid.
Counterbore of the present utility model covers the section edge and has adopted chamfer design, can effectively the chamfering on the counterbore be filled a vacancy and seal, and the strong adaptability to the counterbore chamfering has strengthened sealing effect.
Description of drawings
In order to clearly demonstrate innovative principle of the present utility model and than the technical advantage of existing product, the below by means of accompanying drawing by using possible embodiment of limiting examples explanation of described principle.In the drawings:
Fig. 1 a is the generalized section of counterbore lid side;
Fig. 1 b is the positive schematic diagram of counterbore lid;
Fig. 1 c is the schematic diagram at the counterbore lid back side;
Fig. 2 is the rigging position schematic diagram of counterbore lid and counterbore;
Fig. 3 is the assembly structure schematic diagram of counterbore lid and counterbore.
Embodiment
With reference to the accompanying drawings, Fig. 1 a has shown more detailed sectional drawing of counterbore lid of the present utility model, it comprises: circular plate body, along the edge of this circle plate body to the extended guiding of side shirt rim 1, the terminal outward edge of this guiding shirt rim 1 is provided with chamfering, guiding is distributed with a plurality of shirt rims otch 2 on the shirt rim 1, circular plate body is provided with the through hole 4 that is in the described guiding shirt rim 1, and a side of contiguous described guiding shirt rim 1 is provided with annular chamfer 3 on the circular plate body.
The whole plastics that adopt of the guide rail counterbore lid of the present embodiment are made, and lighter weight is simple in structure.Thereby simple for the manufacture of the mould of this counterbore lid, cost is low, is convenient to batch production.
Consider the tight requirement of combination of the counterbore 6 among counterbore lid and Fig. 2, counterbore lid and counterbore 6 interference fit in design process, and so that in installation process, need not to reach with the destructive method such as knocking, the while can prevent from again covering and counterbore between get loose.
Fig. 2 has represented counterbore lid and the mutual alignment corresponding relation of counterbore before assembling, and Fig. 3 has represented that the rear counterbore lid of assembling and the corresponding position of counterbore concern.
Above-mentioned explanation for the embodiment who uses the utility model innovative principle is for the limiting examples of described principle is provided in the exclusive authority scope that here requires.For example, the quantity of shirt rim otch can be made adjustment according to the variation of the size of counterbore; Through hole can be adjusted as required in covering position; If more suitable elastic material is arranged, the counterbore lid can adopt these material substitution plastics etc.
