Abstract

The invention relates to a clamp for positioning a U-shaped connecting piece. The clamp comprises a positioning module fixedly arranged on a machine tool table top, a threaded connecting piece and a wear-out piece, wherein a connecting hole is formed in a U-shaped connecting piece; a positioning hole corresponding to the connecting hole is formed in the positioning module; the threaded connecting piece penetrates through the connecting hole in the U-shaped connecting piece and is in threaded connection with the positioning hole; and the wear-out piece is arranged between the U-shaped connecting piece and the threaded connecting piece. According to the clamp, the positioning module which is provided with the positioning hole corresponding to the connecting hole in the U-shaped connecting piece is adopted, and the U-shaped connecting piece is fixed on the positioning module through the threaded connecting piece, so that the U-shaped connecting piece can be positioned; and the wear-out piece is additionally arranged between the fixed U-shaped connecting piece and the positioning module, so that the U-shaped connecting piece can be prevented from being worn out, and the stability of the U-shaped connecting piece is further improved.

Description

A kind of positioning fixture of U-shaped connector

Technical field

the invention belongs to field of machining, are specifically related to a kind of positioning fixture of U-shaped connector.

Background technology

along with development of science and technology, in order to reach combining between part and the part, therefore; The connector that different shape occurs, U-shaped connector for example is when the Surface Machining of U-shaped connector; Be all to adopt pincers platform clamping frame to be located at the vertical portion of U-shaped connector mostly, that can process like this has only bottom the U-shaped connector, yet; According to different needs, be in the two sides of U-shaped connector (vertically portion) processing the time, the U-shaped connector revolved turn 90 degrees; Adopt pincers platform clamping frame to be located at the right ends of the U-shaped connector of horizontally set, however when the vertical portion of U-shaped connector be not symmetry, the U-shaped connector fixes inconvenience extremely like this.

Summary of the invention

technical problem to be solved by this invention is the deficiency that overcomes prior art, and a kind of positioning fixture of U-shaped connector is provided.

For solving above technical problem, a kind of technical scheme that the present invention takes is:

The positioning fixture of a kind of U-shaped connector; It comprises the locating module that fixedly installs on the lathe table top; The U-shaped connector is provided with connecting hole; Particularly, locating module is provided with and the connecting hole corresponding positioning hole, and positioning fixture also comprises the threaded connector that the connecting hole that passes the U-shaped connector is threaded with locating hole and is arranged on the wear-out part between U-shaped connector and the threaded connector.

preferably, wear-out part middle part is provided with the hole with the aperture same apertures of locating hole and connecting hole, and presents the U-shaped peristome along what the wear-out part length direction formed the middle part hollow out.

further preferably, threaded connector passes peristome successively, connecting hole is threaded with locating hole.

more preferably, the material of wear-out part is scrap iron, steel, saves production cost the waste recovery utilization.

preferably, the lathe table top is provided with groove, and the locating module lower end is provided with the connecting key with groove fit.

Because the employing of technique scheme, the present invention compared with prior art has the following advantages:

The locating module with locating hole of the corresponding setting of connecting hole on employing of the present invention and the U-shaped connector; Further the U-shaped connector is fixed on the locating module by threaded connector; Thereby realize the location of U-shaped connector; Between fixing U-shaped connector and locating module, set up wear block simultaneously, prevented of the wearing and tearing of U-shaped connector, further improved the stability of U-shaped connector the U-shaped connector.

Description of drawings

are done further detailed explanation below in conjunction with accompanying drawing and concrete embodiment to the present invention.

Fig. 1 looks sketch map for the left side of positioning fixture of the present invention;

Fig. 2 is the partial schematic sectional view of positioning fixture of the present invention;

Fig. 3 is wear block schematic top plan view in the positioning fixture of the present invention;

wherein: 1, lathe table top; 10, groove; 2, locating module; 20, locating hole; 21, connecting key; 3, U-shaped connector; 30, connecting hole; 4, threaded connector; 5, wear-out part.

The specific embodiment

are extremely shown in Figure 3 like Fig. 1; Positioning fixture according to the U-shaped connector of present embodiment; It comprises the locating module 2 that fixedly installs on the lathe table top 1, and U-shaped connector 3 is provided with connecting hole 30, particularly; Locating module 2 is provided with and connecting hole 30 corresponding positioning hole 20, positioning fixture also comprise the threaded connector 4 that the connecting hole 30 that passes U-shaped connector 3 is threaded with locating hole 20 and be arranged on U-shaped connector 3 and threaded connector 4 between wear-out part 5.

The positioning fixture of the U-shaped connector of present embodiment; Further referring to Fig. 2 and shown in Figure 3, wear-out part 5 middle parts are provided with the hole with the aperture same apertures of locating hole 20 and connecting hole 30, and present U-shaped peristome 50 along what wear-out part 5 length directions formed the middle part hollow out; Threaded connector 4 passes peristome 50 successively, connecting hole 30 is threaded with locating hole 20; According to the size that is folded in the U-shaped connector 3 between locating module 2 and the threaded connector 4, regulate the peristome of wear-out part 5 simultaneously, make wear-out part 5 be in the centermost of U-shaped connector 3 green surfaces; Improved U-shaped connector stability; The material of wear-out part 5 is scrap iron, steel simultaneously, saves production cost the waste recovery utilization.Lathe table top 1 is provided with groove 10, and locating module 2 lower ends are provided with the connecting key 21 that cooperates with groove 10.

The locating module with locating hole of the corresponding setting of connecting hole on employing of the present invention and the U-shaped connector; Further the U-shaped connector is fixed on the locating module, thereby wear block has been set up simultaneously in the location of realizing the U-shaped connector between fixing U-shaped connector and locating module by threaded connector; Prevent of the wearing and tearing of U-shaped connector to the U-shaped connector; In addition, regulate wear block, and then improve the stability of U-shaped connector in the position of U-shaped connector green surface.

More than the present invention has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences of doing according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention
