Abstract
The utility model relates to a pin shaft press-loading positioning device, which solves the press-in stability and the accuracy when pressing in, namely, the coaxality between the pin and the shaft. The utility model adopts a U-shaped block as a positioning element which places the pin and a press-in shaft line in a same coaxial line, and the utility model specifically comprises a press-loading portion and a positioning portion. The press-loading portion is constituted by a driving portion which can be a hydraulic portion, air-actuated portion, power-driven portion or a hand-operated portion, a thimble, slide block, and a guide rail. The positioning portion mainly comprises a U-shaped block and a V-shaped block. The pin shaft is located by the positioning portion and is pressed in by the press-loading portion, thereby realizing the press-loading positioning of the pin shaft.
Description
1. technical field
The present invention relates to a kind of pin and press-fit positioner.
2. background technology
At home, press-fit positioning equipment and applied to chain rail joint guide assembly, fields such as small-sized synchronous generator shaft coupling, application of the present invention is very extensive, press-fits position fixing process etc. such as the refrigeration compressor piston pin.
Because it is various pins require to be pressed into the difference of use level, also different to the requirement of pressure; Should be steady, efficient again, and will raise the efficiency and steadily, pin just seems very important with the coaxial alignment in hole.Also will consider specific requirements such as material shape simultaneously, this has higher requirement to being pressed into equipment.The present invention proposes under this background just.
3. utility model summary of the invention
The technical problem that solves:
Mainly solve the stationarity be pressed into and the accuracy when being pressed into, i.e. the alignment of pin and axle.
Technical scheme:
It is setting element that the present invention adopts with U type piece, makes pin and to be pressed into axially bored line coaxial, and its concrete structure comprises: press-fit partly and localization part.Press-fiting part mainly is made up of drive part (driving can be surge, pneumatic, electronic or manual drives), thimble, slide block, guide rail.Localization part mainly is made up of parts such as U type piece, V-blocks.
U type piece (3) can level, also can with the angled placement of horizontal plane, pin (2) is placed in the U type groove of U type piece, plays positioning action.Thimble (1) is connected with driver part, its direction of motion and U type fluted shaft line keeping parallelism.
Beneficial effect:
Adopt this kind invention, what can increase substantially pin press-fits locating speed and precision, and efficient is improved greatly, has reduced pin simultaneously greatly owing to press-fit the damage that cause the location.
4. description of drawings
Shown in Figure 1 is the network for location of U type piece
Thimble (1), under the driving force effect, thimble is to arrow direction, and the bump pin is pressed into pin (or extrusion).
Pin (2) is to press-fit position fixing process, and stressed main body is located it with U type piece.
U type piece (3) as the location to pin, guarantees the alignment of pin and thimble.
5. the specific embodiment:
(1) press-loading device of refrigeration compressor piston pin
(2) press-loading device of automobile engine steam-cylinder piston pin
At first,, can adopt to sell to be contained in advance in piston one stomidium, or the anchor clamps locate mode, when piston places U type piece, can guarantee to sell coaxial with piston hole piston pin prealignment piston stomidium.Then, thimble travels forward under the effect of pneumohydraulic pressure-cylinder driving force, and the pin of various different-diameters steadily is pressed in the hole.In the extrusion process, add V-block at the piston stroke end, the stroke of thimble remains unchanged, and piston stroke will shorten, pin will be extruded from piston by thimble.After being pressed into (or extrusion) release, thimble is steadily got back to original position again under the effect of pneumohydraulic pressure-cylinder driving force.
Claims (4)
1. the present invention relates to a kind of pad positioner, by the pad drive part, pin localization part and slave part are formed, and the setting element that it is characterized in that pin is V-type or U type structure.
2. according to the pad positioner described in the claim 1, the installation that it is characterized in that the U type of its description or V-block be level or tilt.
3. according to claim 1, the pad positioner described in 2, the thimble axis that it is characterized in that drive part is parallel with the side of U type or V-block, and with the axis of bearing pin be coaxial.
4. according to claim 1, the pad positioner described in 2,3 is characterized in that, when being used for the assembling of piston pin, and the axis of pin, the axis of piston is coaxial with the axis that drives thimble.
