Description

Clamping device for clamping cylinder

Technical Field

The utility model relates to the technical field of machining, in particular to a clamping device for clamping a cylinder.

Background

In machining production, especially in the machining of automobile molds, parts such as a material pressing rod and the like are long cylinders, the material pressing end face is a special-shaped face, the special-shaped face needs to be milled by a numerical control machine, and the stability of clamping and fixing is the problem to be solved firstly.

In the processing process, a clamping mode that the lower end face of the cylinder is fixed on the flat transition plate by spot welding is adopted, the bearing elasticity is large during processing, and only small-cut slow-feed processing can be carried out. Has the defects of unstable clamping, long preparation time, slow processing efficiency and low processing precision.

Disclosure of Invention

The utility model aims to provide a simple device for clamping a cylinder, which can be used for conveniently, quickly and stably clamping the cylinder, so as to solve the problems.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: the utility model provides a clamping device for clamping cylinder, includes support, fixed block, movable block and screw thread push rod, fixed block and support fixed connection, the inner chamber is seted up to the fixed block, the inner chamber sets up the notch, the movable block is located the inner chamber of fixed block is connected with the fixed block through the screw thread push rod.

The inner cavity of the movable block is inserted into the cylinder to be clamped from the upper part of the upper inner cavity, the cylinder abuts against the position of the notch, and then the position of the movable block is adjusted by rotating the threaded push rod, so that the movable block and the notch of the fixed block clamp the cylinder together.

As a preferred technical scheme: the notch is a V-shaped groove. The notch may also be of other shapes, as known to those skilled in the art, such as an arc, the main purpose of which is to allow a portion of the outer circumference of the cylinder to be clampingly secured to snap into the notch to prevent displacement of the cylinder.

As further preferred: the V-shaped groove has an angle of 60 degrees. Thereby forming an even 3 point of 60 degrees with the movable block to make the clamping of the cylinder more stable.

As a preferred technical scheme: the support adopts the board-like equipment to form by the fix with screw, the support with the fixed block is different materials to save the material cost and the processing cost of manufacture of device.

Compared with the prior art, the utility model has the advantages that: by adopting the device, the cylinder is only required to be placed into the notch of the fixed block and the threaded push rod is rotated to adjust the position of the movable block so as to clamp the cylinder, and the clamping is simple and convenient; the clamping position of the cylinder is close to the processing end of the cylinder, and an equilateral triangle clamping mode is preferably formed by uniformly dividing 3 points, so that the clamping of the cylinder is more stable, the bouncing caused by processing stress is greatly reduced during processing, larger processing cutting amount and cutting speed can be realized, the processing time is saved, and the processing precision is improved; the device is manufactured in an assembling mode, has a simple structure, is convenient to manufacture, is low in cost, and can meet the requirements of processing and clamping cylinders with various specifications.

Detailed Description

The utility model will be further explained with reference to the drawings.

Example (b):

referring to fig. 1-3, the simple device for vertically clamping the cylinder comprises a support 1, a fixed block 2, a movable block 3 and a threaded push rod 4, wherein the fixed block 2 is assembled on the support 1 by a screw 5, the fixed block 2 is provided with an inner cavity with a V-shaped groove 6, and the movable block 3 is positioned in the inner cavity of the fixed block 2 and is connected with the fixed block 2 through the threaded push rod 4;

when in use, referring to fig. 4, the device is firstly clamped and fixed on a machine tool workbench; thereby rotatory screw thread push rod 4 makes the position of movable block 3 go back and reserve sufficient space of placing the part between the V-arrangement groove of movable block 3 and fixed block 2, then inserts the cylinder A of treating processing and in the V-arrangement groove mouth 6 of fixed block 2 and reserve processing end length, thereby rotatory screw thread push rod 4 is tight fixed with the clamp of the position of adjusting movable block 3 with treating the processing cylinder again.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
