Abstract

The utility model relates to a reading head installation seat of a raster ruler, which is composed of a reading head bracket, an intermediate junction seat, a connecting seat, an installation cock and a rolling needle, can realize the separation adjustment of the reading head relative to two linear displacement and three angular displacement of the raster ruler. The adjustment and locking can be completed simultaneously. The installation seat can adapt to the various requirements of installation positions of the reading head. The utility model is a reading head installation seat, has the advantages of simple structure, convenient adjustment, good versatility, and can be widely used on the devices which use a displacement detecting device with a raster ruler.

Description

Raster ruler read head mount set

The utility model relates to the grating ruler reading head mount pad in the pattern displacement pick-up unit.More particularly, the utility model relates to the read head mount pad of reading from the grating chi.

Grating ruler reading head need to be adjusted the relative position between read head and the grating chi when mounted, promptly adjust the straight-line displacement of X, Y both direction and α, β,

The angular displacement of three directions according to the graphic presentation on the oscillograph, is adjusted when suitable read head is fixed.General read head mount pad can not be realized the adjustment respectively of five directions of read head, when promptly adjusting certain direction, tend to make another direction that has mixed up to change, and when the satisfied back locking of all directions adjustment mount pad, the position that has mixed up is changed, so the adjustment of read head is very time-consuming, trouble.

The purpose of this utility model provides a kind of two straight-line displacements of read head and three angular displacement of realizing and adjusts, adjusts and lock the general read head mount pad of finishing simultaneously independently of one another.

Technical solution of the present utility model is: the read head mount pad is that a V-shaped groove, lower end are arranged on a plane, the plane is the read head bracket that mills a plane on a cylindrical handle, the handle by the upper end; It is the middle Connection Block that mills a plane on a cylindrical handle, the handle that one end has circular hole, an other end that closes with the delthyrium of read head bracket; One end is made up of the installing plate of two slotted holes two threaded holes, the other end the Connection Block and an end of a slotted hole circular hole, an other end that closes with the delthyrium of middle Connection Block.Read head is installed on the read head bracket with two screws.The needle roller of packing in the V-shaped groove of read head bracket in the middle of its cylindrical handle inserts in the circular hole of Connection Block, and withstands on the plane of handle with two screws.The cylindrical handle of middle Connection Block inserts in the circular hole of Connection Block, and withstands on the plane of handle with two screws, on two threaded holes pulling to installation with two screw attachment in its slotted hole.With two slotted holes of two screws the read head mount pad is installed on the body by installing plate.

Adjust the position of mount pad and installing plate respectively along slotted hole, can determine read head with respect to grating chi X to Y to the position.

Adjust two screws that read head is installed on the read head bracket, read head is rotated around needle roller, thus the decision read head with respect to grating chi α to angular position.Adjust two screws on the plane of Connection Block and Connection Block cylindrical handle in the middle of the position, top respectively, can determine read head with respect to grating chi β, The angular position of both direction.

So just realized the separation adjustment of five directions of read head.

Because α, β,

The adjustment of three angular position is existing with two screws, one a tight pine nut, so also finished the locking of read head when adjusting.

Further improvement of the utility model, be on three planes of circular of middle Connection Block and Connection Block, respectively to process two screw holes, read head bracket, middle Connection Block and Connection Block are installed to adapt to the requirement of the various installation sites of read head by different position groupings, made read head mount pad of the present utility model become a kind of general device.

Task of the present utility model comes to this and finishes.

Because read head mount pad of the present utility model can realize read head and finish respectively independently of one another with respect to the adjustment of five directions of grating chi, and the adjustment of three angular displacement and locking finishes simultaneously, thereby makes the adjustment of read head very convenient.Read head mount pad of the present utility model can adapt to the requirement of the various installation sites of read head, is a kind of general device.

Following accompanying drawing has been described an embodiment of the present utility model:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a side view of the present utility model.

Fig. 3 is along the cut-open view of A-A among Fig. 2.

Among Fig. 1 and Fig. 2, read head (11) is installed on the read head bracket (1) by two screws (4), and a needle roller (5) is housed in the V-shaped groove of bracket (1).Connection Block (2) in the middle of the cylindrical handle of read head bracket (1) inserts.The cylindrical handle of middle Connection Block (2) inserts Connection Block (3), in the slotted hole of Connection Block (3), Connection Block (3) is connected on the installing plate (8), in the slotted hole of installing plate (8), read head is connected on the body with two screws (9) with two screws (7).(12) be the grating chi.

Among Fig. 3, the plane in the middle of withstanding with two screws (6) on the cylindrical handle of Connection Block and Connection Block.Respectively process two threaded holes (10) on three planes of the circular of middle Connection Block and Connection Block.

Present embodiment can be realized the separation adjustment of five directions of the relative grating chi of read head, adjusts and locks and finish simultaneously, can adapt to the various installation sites of read head.

Claims

1, a kind of grating ruler reading head mount pad, it is characterized in that: by the upper end is that one " V " shape groove is arranged on a plane, the plane, the lower end is the read head bracket that mills a plane on a cylindrical handle, the handle, it is the middle Connection Block that mills a plane on a cylindrical handle, the handle that one end has the circular hole, the other end that cooperate with the cylindrical handle of read head bracket, one end has circular hole, an other end that closes with the cylinder delthyrium of middle Connection Block that the web joint of one slotted hole is arranged, and an end has two threaded holes, the other ends to have the installation of two slotted holes to pull and a needle roller constitutes.

2, according to the grating ruler reading head mount pad of claim 1, it is characterized in that: Connection Block and Connection Block in the middle of said respectively have two threaded holes on three planes of circular.
