Description
Technical field
The utility model relates to a kind of fixture, is specifically related to the sealed-bearing riveting fixture of a kind of casing and limit lid.
Background technology
In general, the precision of fixture all should be higher than workpiece permissible accuracy, just can process qualified workpiece.The part that precision exceeds is called precision store or the precision nargin of fixture.Precision nargin is used for the wearing and tearing of every error in compensation processing and location, director element.Certainly precision nargin is larger, and the quality of processing work is more stable, and the service life of the consumable accessory of fixture is also longer.But on the other hand, precision nargin is larger, necessarily require the accuracy of manufacture of fixture higher, thereby can sharply increase the manufacturing cost of fixture, the processing cost of workpiece also increases thereupon; Otherwise the precision that fixture is manufactured is less, will make fixture consumable accessory (being mainly location, director element) in fixture change continually, maintenance cycle is short, increases maintenance cost, thereby has increased the processing cost of workpiece.
The fixture that China adopts at present all exists following with individual defect:
Bearing and oil sealing in when location without any spacing, easily cause that it is crooked;
2. stroke, without any spacing, is only stopped oil sealing by hydraulic press after bearing kills when riveting;
3. oil sealing and bearing separation lamination, all without location in the situation that, easily cause the decentraction of oil sealing and bearing, and it is not high to press-fit efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide the sealed-bearing riveting fixture of a kind of casing and limit lid, this fixture easy operating, and Improving The Quality of Products and raising the efficiency, can carry out long-term use.
Technical problem to be solved in the utility model realizes by the following technical solutions:
The sealed-bearing riveting fixture of a kind of casing and limit lid, it comprises pressure head, base plate, is arranged on the pressure mounting base of base plate top, above described pressure mounting base, centre position is provided with Fitted Axles, described Fitted Axles lower end cover has a portable plate, one end at this portable plate is connected with base plate by the axis of guide, below the other end of portable plate and between pressure mounting base, be provided with cylinder-shaped compression spring, described pressure head is connected with Fitted Axles by fillister head screw.
Described portable plate top is provided with prismatic pin, and by this pin, casing and Bian Gai is positioned.
The beneficial effects of the utility model are:
1) utilize the interference fits of polycylindser to carry out correcting product, oil sealing and bearing, ensured the concentricity of product after assembling;
2) on riveting stroke, utilize the position of the axis of guide and Fitted Axles spacing, the axis of guide is pressed onto behind position, and the hydraulic press switch that comes loose can auto-returned by cylinder-shaped compression spring;
3) employing activity prismatic pin in the time of product orientation adopts a small amount of bolt to fix in frock, while carrying out the replacing of product type, more efficient and convenient.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the position relationship structural representation of the utility model and workpiece.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1-2, the sealed-bearing riveting fixture of a kind of casing and limit lid, it comprises pressure head 1, base plate 2, be arranged on the pressure mounting base 3 of base plate 2 tops, above described pressure mounting base 3, centre position is provided with Fitted Axles 4, Fitted Axles 4 lower end covers have a portable plate 5, one end at this portable plate 5 is connected with base plate 2 by the axis of guide 6, below the other end of portable plate 5 and between pressure mounting base 3, be provided with cylinder-shaped compression spring 7, on riveting stroke, utilize the axis of guide 6 spacing with the position of Fitted Axles 4, the axis of guide 6 is pressed onto behind position, coming loose hydraulic press switch can auto-returned by cylinder-shaped compression spring 7, pressure head 1 is connected with Fitted Axles 4 by fillister head screw 8, utilizes the interference fits of polycylindser to carry out correcting product, oil sealing and bearing, has ensured the concentricity of product after assembling,
Portable plate 5 tops are provided with prismatic pin 9, and by this pin, the casing of workpiece 10 and Bian Gai are positioned.In the time of product orientation, employing activity prismatic pin 9 adopts a small amount of bolt to fix in frock, while carrying out the replacing of product type, more efficient and convenient.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
