Description

Matrix type flexible clamp

Technical Field

The utility model relates to an anchor clamps, especially a matrix flexible clamp.

Background

The special fixtures of the existing machining equipment, such as a lathe, a milling machine and the like, need to be consistent with the surface modeling of parts, are tightly attached, can generate enough large friction force to clamp the parts only when being accurately positioned, prevent the parts from moving or shaking, and need to be frequently adjusted and positioned in the use process of the fixtures, so that the fixtures are suitable for clamping different parts, as shown in figure 1.

As shown in fig. 2, the conventional fixture for a three-coordinate measuring machine needs to manufacture a conformal fixture according to the shape of a part to be detected to fix the part to be detected, particularly, the part to be detected is in a curved shape, and needs to manufacture a curved block completely conformal to the part to be detected, and after the part is placed in the curved block of the fixture, the part is positioned by using the curved features. For the completely conformal curved surface block clamp, when the shape and the positioning requirements of the part are changed, the curved surface block clamp meeting the requirements needs to be manufactured again, the manufacturing difficulty is high, the construction period is long, and the manufacturing cost of the clamp is increased.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a overcome not enough of above-mentioned problem, provide a matrix flexible clamp.

In order to overcome the technical problem, the utility model discloses a technical scheme is:

including base, support column, spring, cylinder, tight briquetting of clamp and gland nut, characterized by: the base both sides set up the end plate, and the intermediate plate of base is connected with the end plate of both sides respectively, and the intermediate plate of base is connected respectively to support column one end, and the lower terminal surface of base is connected respectively to the other end of support column, the intermediate plate equipartition array round hole of base, and the round hole department at the intermediate plate is installed respectively to spring one end, and the other end of spring is connected with the cylinder respectively, and gland nut sets up in the left end plate department of base, presss from both sides tight briquetting and is connected with gland nut.

Furthermore, the upper end of the cylinder is provided with a convex hemispherical head.

Compared with the prior art, the beneficial effects of the utility model are that: the fixture can be mounted, clamped and positioned according to parts in any shapes, the fixture does not need to be replaced, the universality and interchangeability are high, the processing cost of the fixture is saved, the production efficiency is improved, and the processing period of the parts is shortened.

Detailed Description

As shown in fig. 1, the clamp 1 is a clamp 1 commonly used in the existing machining equipment, the clamp 1 needs to be manufactured through the shape of a part 2, the clamp 1 needs to be consistent with the surface shape of the part 2, the attachment is tight, the positioning is accurate, and enough friction force can be generated to clamp the part, so that the part is prevented from moving or shaking.

As shown in fig. 2, the conventional fixture for a three-coordinate measuring machine needs to manufacture a conformal fixture 4 according to the shape of a detected part 3 to fix the detected part 3, particularly, the detected part 3 is in a curved shape, and the conformal fixture 4 needs to be manufactured to be completely consistent with the curved contour of the detected part 3 so that the detected part 3 can be placed in the conformal fixture 4 to be fixed, and the detected part 3 is positioned by using the curved features.

As shown in fig. 3-5, the utility model relates to a matrix flexible clamp, including base 10, support column 9, spring 8, cylinder 7, press from both sides tight briquetting 6 and gland nut 5, wherein: the base 10 both sides set up end plate 12, the intermediate plate 13 of base 10 is connected with the end plate 12 of both sides respectively, the intermediate plate 13 of base 10 is connected respectively to support column 9 one end, the lower terminal surface of base 10 is connected respectively to the other end of support column 10, the 13 equipartition array round holes of intermediate plate of base 10, the round hole department at intermediate plate 13 is installed respectively to spring 8 one end, spring 8's the other end is connected with cylinder 7 respectively, gland nut 5 sets up in the left end plate 12 department of base 10, it is connected with gland nut 5 to press from both sides tight briquetting 6.

Further, the upper end of the cylinder 7 is a convex hemispherical head.

The utility model discloses an operating principle is, place work piece 11 on the bellied hemisphere head of cylinder 7, under the effect of spring 8, make the cylinder 7 compression downwards with the work piece contact through the dead weight of work piece 11, cylinder 7 contacts with it along with the profile along with the unsmooth undulation that work piece 11's shape produced, at this moment, gland nut 5 is screwed up manually, gland nut 5 promotes and presss from both sides tight briquetting top 6, the clamp force that will produce passes through the conduction of each cylinder 7 and relies on mutual frictional force to realize that cylinder 7 is fixed to the clamp of work piece 11 presss from both sides tightly.
