Abstract

The utility model relates to a large-torque positioning pin installation and pressing-in tooling, which comprises a square positioning frame and is characterized in that a micrometer is installed at the top part of the positioning frame, a T-shaped handle is installed on an ejector rod of the micrometer, the ejector rod is in threaded fit with the positioning frame, a pressing head of the micrometer is matched with a pressing block, a countersink is formed in the bottom part of the pressing block, a positioning pin is embedded in the countersink, and the positioning pin stretches into a positioning hole of a positioning plate. The large-torque positioning pin installation and pressing-in tooling has the advantages that the structure is simple, the tooling is flexible and convenient to use, the magnitude of force applied to the positioning pin can be accurately controlled, the positioning pin can be accurately pressed into the workpiece pin hole, and the positioning accuracy of the positioning pin is guaranteed.

Description

High pulling torque 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, there is direct relation with the active force that it is applied, the precision of the necessary big or small guarantee alignment pin that guarantees pressing-in force, when especially required pressing-in force ratio is large, must guarantee the steady and accurate of pressure.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of high pulling torque 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, can accurately alignment pin be pressed in workpiece pin-and-hole, guarantee the positioning precision of alignment pin.

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

High pulling torque alignment pin is installed pressing tool, comprise square locating rack, locating rack top is provided with silk table, on the push rod of silk table, T-shaped handle is installed, push rod and locating rack are threaded engagement, and 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, T-shaped handle is connected by bolt and push rod;

Preferably, pressure head coordinates with the bellmouth on briquetting.

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, push rod and locating rack are threaded engagement, and the end of push rod arranges handle, can to alignment pin, implement large active force effortlessly, its order is pressed into alignment pin in the pin-and-hole of workpiece reposefully, guarantee the location 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, T-shaped handle 3 is installed, T-shaped handle 3 is connected by bolt and push rod 7, facilitate dismounting or the replacing of T-shaped handle 3, push rod 7 is threaded engagement with locating rack 1, while rotating T-shaped handle 3, push rod 7 moves downward, and laborsaving, for coordinating tighter alignment pin 9 especially applicable with workpiece 10, and more steady when push rod 7 moves down, 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, revolves the push rod of silk table 27 in the screwed hole of locating rack 1, and T-shaped handle 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, rotates T-shaped handle 3 and makes the downward translation of push rod 7, the reading of Real Time Observation silk table 2, and when the size of power reaches requirement, the T-shaped handle 3 that stops operating, alignment pin 9 is accurately 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.
