Description

Titanium bar clamp

Technical Field

The utility model relates to an anchor clamps technical field especially relates to a titanium stick anchor clamps.

Background

The jig is a device for fixing a processing object to occupy a correct position for receiving construction or inspection in a machine manufacturing process.

In factory production, because titanium bars have the characteristics of being large, long or heavy, the used clamp is usually used for transferring the titanium bars or carrying out reprocessing operation in the clamping state, so that labor force is saved and working efficiency is improved. Because the titanium bar is of various types and has a wider range of external dimensions, the clamping requirements of the titanium bar can be met by manufacturing or purchasing a plurality of clamps with different specifications, and the production cost is correspondingly increased. Meanwhile, as the titanium rods corresponding to each clamp are one or more, when the titanium rods exceeding the clamping range of the clamp need to be clamped, the clamps need to be replaced, so that the clamps need to be frequently replaced for simultaneously producing the titanium rods with various specifications so as to meet the production requirement, the labor force is correspondingly increased, and the production efficiency is reduced. Sometimes, in order to save time and reduce the replacement times of the clamp, the unmatched clamp is used for clamping the titanium rod, and the problems that the clamping is not tight when the large clamp clamps the small titanium rod, and the titanium rod is easy to fall off to cause potential safety hazards exist; when the small clamp clamps the large titanium rod, the clamping surface is too small, the clamping force is insufficient, the titanium rod can fall off, the small clamp can be damaged, and normal production is affected.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to the titanium bar clamp shown in fig. 1-5, the clamp 1 is composed of single clamps which are identical in structure and symmetrically arranged, wherein each single clamp comprises a first clamp 11, a second clamp 12 is movably nested in the first clamp 11, and an adjusting device for switching between the second clamp 12 and the first clamp 11 to clamp the titanium bar independently is arranged between the second clamp 12 and the first clamp 11. The adjusting device can select a proper first clamp 11 and a proper second clamp 12 to carry out clamping operation according to the peripheral size of a clamped titanium rod under the condition that the clamps are not detached. The problem that a large clamp cannot clamp a small titanium rod tightly and the problem that the small clamp can clamp the large titanium rod easily drops is solved. And the variable clamp also solves the problem of frequent replacement of different clamps, saves physical labor and improves the efficiency of continuous work.

Specifically, a first V-shaped clamping surface 11a is arranged on one side of the first clamp 11, a cavity 11b which is communicated with the first V-shaped clamping surface 11a is formed in the first clamp 11, the second clamp 12 is movably embedded in the cavity 11b towards the first V-shaped clamping surface 11a, and the second clamp 12 is provided with a second V-shaped clamping surface 12a which is in the same direction as the first clamp 11 and is smaller than the first V-shaped clamping surface 11a as a whole. The first V-shaped clamping surface 11a is used for clamping a large titanium rod, and the second V-shaped clamping surface 12a is used for clamping a small titanium rod. The adjusting device is arranged between the second clamp 12 and the bottom surface of the cavity 11b, and the second V-shaped clamping surface 12a is in contact clamping with the titanium rod in a staggered mode with the first V-shaped clamping surface 11a through the adjusting device. Namely, according to the size of the titanium rod to be actually clamped, the second clamp 12 is adjusted to move in the cavity 11b through the adjusting device, so that the second V-shaped clamping surface 12a is positioned at the inner side or the outer side of the first V-shaped clamping surface 11a, and the independent clamping of the first clamp 11 or the second clamp 12 is completed. The structure enables real-time switching under the condition that the clamp body is not detached, and the working efficiency is improved.

In order to reduce the difficulty of operating the adjusting device, the adjusting device is a spring 2 uniformly distributed between the second clamp 12 and the bottom surface of the cavity 11b, and convex blocks 100 for sleeving and positioning the spring 2 are correspondingly arranged on the surface of the second clamp 12 and the bottom surface of the cavity 11 b. The bump 100 prevents the falling of the spring 2. The working principle is as follows: in an unclamped state, the second V-shaped clamping surface 12a is located on the outer side of the first V-shaped clamping surface 11a due to the elastic force of the spring 2, and the second V-shaped clamping surface 12a is used for clamping a titanium rod with a small peripheral size and light weight under the action of the spring 2; when the peripheral size of the titanium rod is larger and the mass is heavier, the body of the clamp 1 can be clamped by the larger external force of mechanical equipment, the acting force of the titanium rod is on the second V-shaped clamping surface 12a (the second clamp 12) and compresses the spring 2, so that the second clamp 12 moves towards the bottom surface of the cavity 11b, meanwhile, the second V-shaped clamping surface 12a is gradually positioned at the inner side of the first V-shaped clamping surface 11a, and the titanium rod is contacted with the inner wall of the first V-shaped clamping surface 11a and is gradually clamped. The process realizes the clamping of the titanium rods with different sizes and weights to adapt to the variable clamp, thoroughly solves the problem that different clamps need to be replaced continuously by manpower, and has the function of automatic adjustment according to the titanium rods.

In order to improve the safety of the variable clamp, first shoulders 11c are symmetrically arranged at the intersection of the cavity 11b and the first V-shaped clamping surface 11a, and a second shoulder 12b which is matched with the first shoulder 11c and limits the second shoulder is arranged on one side, close to the spring 2, of the second clamp 12. The cooperation of the two shoulders avoids the risk that the second clamp 12 will fall off the first piece of furniture, and at the same time reduces the stress of the spring 2 when the titanium rod is not clamped.

In order to facilitate the quick installation of the clamp body and mechanical equipment, a through hole 101 for installation is arranged on one side of each single clamp, which is far away from the first V-shaped clamping surface 11 a. The through hole 101 can be quickly installed with mechanical equipment, and the installation angle of the clamp can be adjusted.

The principle of the utility model is that: by the fixture, the titanium rods with different sizes and weights can be clamped without replacing the fixture. The specific operation mode is as follows: the elastic force of the spring 2 enables the second V-shaped clamping surface 12a to be positioned at the outer side of the first V-shaped clamping surface 11a, and the second V-shaped clamping surface 12a is used for clamping a titanium rod with a small peripheral size and light weight under the action of the spring 2; when the peripheral size of the titanium rod is larger and the mass is heavier, the body of the clamp 1 can be clamped by the larger external force of mechanical equipment, the acting force of the titanium rod is on the second V-shaped clamping surface 12a (the second clamp 12) and compresses the spring 2, so that the second clamp 12 moves towards the bottom surface of the cavity 11b, meanwhile, the second V-shaped clamping surface 12a is gradually positioned at the inner side of the first V-shaped clamping surface 11a, and the titanium rod is contacted with the inner wall of the first V-shaped clamping surface 11a and is gradually clamped.
