Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clamps, in particular to a workpiece clamp capable of adapting to multidirectional deformation. BACKGROUND

[0002] Conventional workpiece parts and the like are manufactured in various ways, such as casting, forging, stamping, injection molding, and mold pressing. Each of the various manufacturing methods has its own advantages and disadvantages, and therefore the manufacturing methods corresponding to various parts with different requirements are also different.

[0003] Casting is a metal hot working process mastered by humans relatively early, with a history of about 6000 years. China entered the heyday of bronze casting between about 1700 BC and 1000 BC, and the technology has reached a relatively high level. Casting refers to the processing method of melting solid metal into liquid and pouring it into a specific shaped mold, and then solidifying it into a shape. The cast metals include copper, iron, aluminum, tin, lead, etc. The materials of ordinary molds are raw sand, clay, water glass, resin, and other auxiliary materials. Special casting molds include investment casting, lost foam casting, metal mold casting, ceramic mold casting, etc.

[0004] The advantages and disadvantages of the casting processing method are also very obvious: advantages: 1. Complex-shaped parts, especially complex internal cavity blanks, can be produced; 2. Widely adaptable, as industrial commonly used metal materials can be cast, from a few grams to a few hundred tons; 3. The source of raw materials is wide, and the price is low, such as scrap steel, scrap parts, and cuttings; 4. The shape and size of the castings are very close to the parts, generally within 1-2 mm, reducing the cutting amount and belonging to non-cutting processing; 5. Widely used and easy to manufacture.

[0005] Disadvantages: 1. The mechanical properties of castings are not as good as forgings, and the organization is coarse, with many burrs, an unsmooth surface, many defect types, and difficult quality control; 2. In sand casting, the labor intensity of workers is high for single-piece and small-batch production; 3. The quality of castings is unstable, the process is complex, and many defects are easily produced.

[0006] The casting part is formed by hot melting and casting and cooling. Basically, all casting materials will have thermal expansion and cold shrinkage. Only the proportion is different. The body shrinkage of conventional copper materials in metal mold casting is about 1%-3%. Therefore, the size of basically all casting blanks will deviate from the designed size. After casting is completed, it also needs to be processed. The casting parts are used in large quantities in the bathroom industry. After casting is completed, they also need to be machined again. The cutting machining of the casting part needs to use a clamp to stably clamp the workpiece, and then use a machine tool to perform metal cutting machining. However, the size of the casting blank is unstable due to the change in the shrinkage amount, which causes the clamp to be difficult to stably clamp the casting part during subsequent processing. During the processing, the phenomena of tool jumping and tool shaking easily occur. Moreover, because the appearance of the bathroom casting blank is mostly self-designed, the shape is irregular and cannot be directly machined by using standard materials. Therefore, most of them are cast into shapes. Because the body shrinkage of the casting blank is unstable, and the size of the casting part is different after the post-processing processes such as shakeout and shot blasting, the deformation amount is also different. The conventional square clamp cannot adapt to the size of each casting part, which causes the size of the casting workpiece to be unstable during processing, and the smoothness and thread stability are also unstable. Especially for kitchen and bathroom faucets, the conventional four-inch and eight-inch faucets are H-shaped faucets. The center distance between the two water inlet pipes is generally 101.6 and 203.2. Under the condition of 1%-3% body shrinkage, the size difference is 1-2 mm, which is seriously unmatched with the designed square clamp. Therefore, a clamping clamp that can adapt to the deformation of the casting part due to the body shrinkage is needed to clamp the casting workpiece with different deformation amounts.

[0007] Based on this, the present application designs a workpiece clamp capable of adapting to multi-directional deformation to solve the above problems. SUMMARY

[0075] The rotating positioning seat 11 is provided with a plurality of positioning lock holes 112 at the bottom, the transverse guide seat 21 is provided with a plurality of adjustment lock holes 213 at the bottom, and the clamping sliding block 3 is provided with a plurality of adjustment holes 32 at the top. The plurality of positioning lock holes 112 and the plurality of adjustment lock holes 213 are locked in position corresponding to the adjustment holes 32 matched and installed below, the adjustment lock holes 213, the positioning lock holes 112 and the adjustment holes 32 are all waist-shaped holes, the plurality of adjustment holes 32 are not connected longitudinally and transversely, the adjustment holes 32 are provided at the top of the clamping sliding block 3, the adjustment lock holes 213, the positioning lock holes 112 and the adjustment holes 32 are horizontally corresponding, and the transverse guide seat 21 is installed and locked at the top of one clamping sliding block 3 by passing through the adjustment lock holes 213, the positioning lock holes 112 and the adjustment holes 32, so that the rotating positioning seat 11 can be conveniently locked at the top of another clamping sliding block 3, thereby facilitating clamping, and the waist-shaped holes can be adjusted to conveniently adjust the installation position of the transverse guide seat 21 and the rotating positioning seat 11.

[0076] In use, the clamping operation is performed by sliding the clamping blocks 3 on the base 4 to close and clamp, the two clamping blocks 3 are continuously closed to make the first clamping assembly 1 and the second clamping assembly 2 close to each other to clamp and stably contact the workpiece, and start clamping and extruding, when the center distance of the two pipes of the pipe fitting deviates, the transverse sliding block 23 slides transversely on the inner side of the transverse guide seat 21, and the expanding sliding block 13 slides on the inner side of the assembling groove 122 of the rotating block 12, and the clamping die groove 5 on the transverse sliding block 23 is aligned with the expanding sliding block 13, so that the expanding sliding block 13 automatically slides outward under the closing pressure to adapt to the size deviation of the cast pipe fitting;

[0077] Because the clamping die groove 5 on the positioning clamping block 22 and the rotating block 12 cannot slide transversely, the positioning is more accurate, and one side of the pipe can be clamped conveniently, therefore the two clamping die grooves 5 on the positioning clamping block 22 and the rotating block 12 which are relatively fixed are closed to clamp one pipe of the cast fitting, and the expanding sliding block 13 and the transverse sliding block 23 transversely translate to adapt to the position deviation of the center distance of the pipe, under the action of external force, the expanding sliding block 13 and the transverse sliding block 23 transversely translate under the action of force to clamp the other pipe of the cast fitting, thereby stably clamping the two pipes of the cast pipe fitting;

[0078] When the diameters of the two vertical pipes of the pipe fitting deviate, the rotating block 12 rotates along the vertical rotating shaft 121, the rotating block 12 deflects to horizontally deflect inward on one side and outward on the other side, thereby forming stable clamping, so that the device can be applied to clamping pipes with different diameters.
