In the machining process of a machine tool, a corresponding clamp is usually arranged on the machine tool to fix a part to be machined, and a locating plate (also called a reference plate) is a tool for fixing the clamp in a proper position on the machine tool.

Chinese patent CN202752717U discloses a reference plate device, which comprises a square base with a horizontal surface, wherein the top surface of the base is provided with an X positioning slot and a Y positioning slot which are perpendicular to each other and parallel to the side of the base respectively, the base is equally divided into four parts by the X positioning slot and the Y positioning slot to form four reference tables, each reference table is provided with a first screw hole, and the four first screw holes are symmetrically distributed with the X positioning slot and the Y positioning slot. The reference sheet device simplifies the clamping and positioning steps before processing, reduces the operation error and improves the processing precision and efficiency.

However, when positioning is performed using the spacer, since the jig needs to be moved to a correct position, the clearance groove of the reference table receives a force applied by the jig during the movement of the jig, and particularly, when the jig and the spacer are just brought into contact with each other, the force applied by the movement of the jig is large. The top surface of the existing reference table is not provided with a corresponding buffer structure, so that the top surface of the reference table is frequently broken, and the service life of the positioning plate is influenced.

Further, the bending plate has three bending points.

Further, the inside of avoiding the dead slot has triangle breach, triangle breach is isosceles triangle, the apex angle of triangle breach is located avoid the innermost side of dead slot.

Further, the angle range of the vertex angle theta of the triangular notch is 60-90 degrees.

Further, a positioning column is arranged on the side face of the reference table and protrudes from the reference table towards the positioning groove.

Further, a side surface of the reference table has a positioning groove recessed from the positioning groove toward the reference table.

After the technical scheme is adopted, the utility model discloses an effect is: the locating plate with the structure not only reduces operation errors and improves processing precision and efficiency, but also can effectively buffer acting force generated during clamp installation and prolong service life.

Detailed Description

The technical solution of the present invention is further described below by way of examples:

the utility model provides a spacer that machine tool was used, it is shown with fig. 2 to combine, and the spacer is formed by stainless steel material, and the spacer includes: base 1, four benchmark platforms 2 and four roofs 3, base 1 is the cuboid shape, benchmark platform 2 is protruding from the upper surface of base 1, and four benchmark platforms 2 are located four bights of base 1 respectively, form two constant head tanks 4 between four benchmark platforms 2, two constant head tanks 4 are located an X constant head tank 41 and a Y constant head tank 42 respectively, X constant head tank 41 and Y constant head tank 42 mutually perpendicular, roof 3 is fixed at the upper surface of benchmark platform 2, and empty groove 31 has between the upper surface of roof 3 and benchmark platform 2. In this example, the splines are 54X 54mm splines.

Specifically, the reference table 2 has a first screw hole 51, and the positioning groove 4 has a second screw hole 52. The first screw holes 51 cooperate with screws for fixing the reference table 2 to the jig, and the second screw holes 52 cooperate with screws for fixing the spacer to the machine tool.

In the present invention, as shown in fig. 3, a bending plate 32 is disposed in the clearance groove 31, the upper end of the bending plate 32 is fixed to the top plate 3, and the lower end is fixed to the reference table 2. During the installation process of the clamp, the bending plate 32 can buffer the acting force generated by the clamp, and the possibility of the top plate 3 breaking is reduced.

Specifically, the bending plate 32 has three bending points, i.e., in the shape of the letter "W" rotated by 90 °, which can improve the cushioning ability of the bending plate 32, further reducing the possibility of breakage of the top plate 3.

Specifically, the inside of clearance groove 31 (where top plate 3 is fixed to the upper surface of reference table 2) has a triangular notch 33, where triangular notch 33 is an isosceles triangle, and vertex angle θ of triangular notch 33 is located at the innermost side of clearance groove 31. More specifically, the apex angle θ of the triangular notch 33 is in the range of 60 ° to 90 °. The inner side of the existing clearance groove 31 is shaped like the letter Contraband, compared with the prior art, the triangular notch 33 is arranged to provide a swinging space for the top plate 3, and the corresponding swinging is generated under the condition of bearing acting force, so that the problem of breakage is avoided.

Specifically, as shown in fig. 4, the reference table 2 has a positioning column 21 on a side surface thereof, and the positioning column 21 projects from the reference table 2 toward the positioning groove 4. When the clamp is installed, the positioning columns 21 are engaged with the grooves at the bottom of the clamp, so that the installation of the clamp is guided, and the acting force generated on the top plate 3 when the clamp is installed is reduced.

More specifically, the side surface of the reference table 2 also has a positioning groove 22, and the positioning groove 22 is recessed from the positioning groove 4 toward the reference table 2. When the clamp is installed, the positioning groove 22 is engaged with the convex column at the bottom of the clamp to guide the installation of the clamp, and further reduce the acting force generated on the top plate 3 when the clamp is installed.

Therefore, the positioning sheet with the structure not only reduces operation errors and improves processing precision and efficiency, but also can effectively buffer acting force generated during clamp installation and prolong service life.
