Abstract

The invention discloses a scribing compass with the needle bar being replaceable. The scribing compass comprises a first scribing compass leg, a second scribing compass leg, a C-shaped clamping spring, an adjusting screw, a first needle bar and a second needle bar. The upper ends of the first scribing compass leg and the second scribing compass leg are respectively connected with two ends of the C-shaped clamping spring; a first fixed ring and a second fixed ring are respectively arranged in the middles of the first scribing compass leg and the second scribing compass leg; the adjusting screw is arranged in the second fixed ring; the other end of the adjusting screw is connected with an adjusting nut after passing through the first fixed ring; the first needle bar and the second needle bar are respectively arranged at the lower ends of the first scribing compass leg and the second scribing compass leg; a first needle point and a second needle point are arranged at the lower ends of the first needle bar and the second needle bar by a first welding material and a second welding material. The scribing compass is reasonable in structural design and convenient to use, and can effectively solve the practical problem of material waste caused by the fact that an existing scribing compass needs to be scrapped after needle points are broken.

Description

Planing of a kind of replaceable shank

Technical field

The present invention relates to scribing by bench worker instrument, be specifically related to planing of a kind of replaceable shank。

Background technology

Pincers worker is the very important work post of machine industry, and along with the extensive use of the fast-developing and high-end Precision Manufacturing Technology of equipment manufacture, pincers worker status in manufacturing industry is also more and more higher。Line is one of basic skill of pincers worker, and the degree of accuracy of line and definition directly influence the surface quality of following process。The instrument of line mainly has scriber, plans, tosecan and vernier height gauge, the instrument being to draw circle or circular arc of wherein planing。Carefully, sharp, hard, crisp be the feature plan, especially with planing of copper bond hard alloy needle point, very easily damage needle point。The needle point plan, once fracture, not only can affect the progress of line work, and be difficult to reparation and reuse, generally scrap process, thus causing a large amount of wastes of material of planing。

Chinese patent also has some utility model improved planing and inventions, but its technical scheme exists operation inconvenience, must separate with protection part when use is plan, and exists and protects device loss easily damaged, easy, the technological deficiency such as yielding。

Summary of the invention

It is an object of the invention to provide a kind of simple in construction, easy to use prevent what needle point from fractureing to plan; there is needle point frangibility in used the planing that it can solve to be mentioned in background technology, and is difficult to repair the technical problem of protection fragile, the yielding and easy loss of device used again and exist in state-of-the-art technology scheme。

For reaching above-mentioned purpose, planing of a kind of replaceable shank of the present invention, it includes plan lower limb one, lower limb two of planing, C-type clamp spring, adjustment screw, shank one and shank two, described plan lower limb one and be connected with the two ends of C-type clamp spring respectively with the upper end of lower limb two of planing, plan lower limb one and the centre of lower limb two of planing is respectively equipped with retainer ring one and retainer ring two, being provided with adjustment screw in described retainer ring two, the described other end regulating screw is connected with adjusting nut after retainer ring one；The lower end of described plan lower limb one and lower limb two of planing is respectively equipped with shank one and shank two；Described shank one and the lower end of shank two are provided with needle point one and needle point two respectively through welding material one and welding material two。

In technique scheme, described plan lower limb one and be connected by screw thread with shank one and shank two with lower limb two of planing。

Described shank one and the upper end of shank two are respectively equipped with regular hexahedron one and regular hexahedron two。

After adopting technique scheme, after some needle point plan fractures, as long as the shank of rotary folding broken needle point takes off from plan lower limb one or lower limb two of planing, replace with new shank can reuse, thus avoiding to scrap, because some needle point of planing fractures, the problem processed and cause waste of material。

Accompanying drawing explanation

Fig. 1 is the structural representation plan of a kind of replaceable shank。

Fig. 2 is A place zoomed-in view in Fig. 1。

Accompanying drawing is respectively designated: lower limb one of 1, planing, 11, retainer ring one, 2, lower limb two of planing, 21, retainer ring two, 22, welding material two, 23, needle point two, 3, C-type clamp spring, 4, turning handle, 5, regulate screw, 51, adjusting nut, 6, shank one, 61, regular hexahedron one, 7, shank two, 71, regular hexahedron two, 62, welding material one, 63, needle point two, 72, welding material two, 73, needle point two。

Detailed description of the invention

Below in conjunction with accompanying drawing, a kind of planing of replaceable shank of the present invention is described further:

As seen from Figure 1, the present invention it include planing lower limb 1, lower limb 22 of planing, C-type clamp spring 3, regulate screw 5, shank 1 and shank 27, described plan lower limb 1 and be connected with the two ends of C-type clamp spring 3 respectively with the upper end of lower limb 22 of planing, plan lower limb 1 and the centre of lower limb 22 of planing is respectively equipped with retainer ring 1 and retainer ring 2 21, being provided with adjustment screw 5 in described retainer ring 2 21, the described other end regulating screw 5 is connected with adjusting nut 51 after retainer ring 1；The lower end of described plan lower limb 1 and lower limb 22 of planing is respectively equipped with shank 1 and shank 27；Described shank 1 and the lower end of shank 27 are provided with needle point 1 and needle point 2 73 respectively through welding material 1 and welding material 2 72。

The using method of the present invention is: when use is plan, and first shank 1 and shank 27 are installed to the lower end of plan lower limb 1 and lower limb 22 of planing；Rotating adjusting nut 51 again, two lower limbs plan naturally are opened under the effect of C-type clamp spring 3, thus the distance between adjustable needle point 1 and needle point 2 73 by the radius of drafting circular arc；Hold turning handle 4, circle or circular arc can be drawn on the material specified；When some of needle point 1 pin plan and point 2 73 fractures, as long as it is taken off from plan lower limb 1 or lower limb 22 of planing, replace with one new。

In the present embodiment, for the ease of taking off shank 1 and shank 27, described shank 1 and the upper end of shank 22 are respectively equipped with regular hexahedron 1 and regular hexahedron 2 71。

In the present embodiment, for the ease of installing and unloading lower needle bar 1 and shank 27, described plan lower limb 1 and be connected by screw thread with shank 1 and shank 27 with lower limb 22 of planing。

Present configuration is reasonable in design, use is flexible, can effectively solve used plan to fracture must scrap process after needle point thus causing the realistic problem of waste of material。
