Abstract

The utility model relates to a locating pin mounting pressing-in tool, comprising a square positioning frame, wherein a screw thread meter is mounted on the top of the positioning frame; a platen is mounted on a top rod of the screw thread meter; a pressing head of the screw thread meter is matched with a pressing block; a counter bore is formed in the bottom of the pressing block; a locating pin is embedded into the counter bore; the locking pin stretches into a location hole of a locating plate. The locating pin mounting pressing-in tool is simple in structure, flexible and convenient to use, and capable of accurately controlling the magnitude of the applied force on the locating pin, and ensuring the location precision of the locating pin.

Description

Alignment pin is installed pressing tool

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to a kind of alignment pin to be installed on to the pressing tool in workpiece locating hole.

Background technology

Alignment pin plays positioning action on workpiece, the positioning datum that it is often processed as workpiece, if can not guarantee required precision, will certainly affect the machining accuracy of workpiece, and under some occasion, whether alignment pin installation meets the requirements, and has direct relation with the active force that it is applied, and must guarantee the precision of the big or small guarantee alignment pin of pressing-in force.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of alignment pin that pressing tool is installed, and it is simple in structure, flexible and convenient to use, can accurately control the size that alignment pin is applied to power, guarantees the positioning precision of alignment pin.

The technical scheme that the utility model adopts is as follows:

Alignment pin is installed pressing tool, comprises square locating rack, and locating rack top is provided with silk table, on the push rod of silk table, platen is installed, the pressure head of silk table coordinates with briquetting, and briquetting bottom is with counterbore, described counterbore is embedded in alignment pin, and alignment pin stretches in the locating hole of location-plate;

Further technical scheme is as follows:

Preferably, platen is connected by bolt and push rod;

Preferably, pressure head coordinates with the bellmouth on briquetting;

Preferably, push rod and locating rack are matched in clearance.

The utility model has the advantage of: by silk gauge pressure on alignment pin, directly can show the size of the power that alignment pin is applied, the power that prevents is excessive or the too small positioning precision of alignment pin that causes is undesirable, finally affects the machining accuracy of workpiece, and simple in structure, flexible and convenient to use.

Accompanying drawing explanation

Fig. 1 is use state diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 1, the utility model comprises square locating rack 1, locating rack 1 top is provided with a table 2, on the push rod 7 of silk table 2, platen 3 is installed, platen 3 is connected by bolt and push rod 7, facilitate dismounting or the replacing of platen 3, push rod 7 is matched in clearance with locating rack 1, platen 3 is applied to the effect of making used time push rod 7 and can not be subject to resistance of power, the bellmouth that the pressure head 8 of silk table 2 coordinates with briquetting 4 coordinates, pressure head 8 is bullet, can make pressure head 8 fully contact with briquetting 4, the power that briquetting 4 is applied balance more, briquetting 4 bottoms are with counterbore, described counterbore is embedded in alignment pin 9, alignment pin 9 stretches in the locating hole of location-plate 5, described locating hole plays guide effect to alignment pin 9, prevent that it from pressing down run-off the straight in process, cause being pressed into precision undesirable, briquetting 4 is subject to equilibrium of forces also most important to the state that is pressed into of alignment pin 9,

Using method of the present utility model is as follows:

The first step, is fixed on locating rack 1 on operating desk by the bolt hole 6 on locating rack 1;

Second step, inserts the push rod of silk table 27 in the through hole of locating rack 1, and platen 3 is connected simultaneously on push rod 7;

The 3rd step, is placed in location-plate 5 on the surface of workpiece 10, makes the pin-and-hole on locating hole and the workpiece 10 of location-plate 5 just right;

The 4th step is inserted alignment pin 9 in the locating hole of location-plate 5;

The 5th step, pressure piece 4 is also enclosed within on alignment pin 9 counterbore on it, makes the bellmouth on briquetting 4 coordinate with pressure head 8 simultaneously;

The 6th step, applies the effect of downward force to platen 3, the reading of Real Time Observation silk table 2, and when the size of power reaches requirement, the size of confining force is constant, until alignment pin 9 is pressed in the pin-and-hole 11 of workpiece 10.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
