Description

Technical Field

[0001] The utility model relates to the technical field of grinding machine equipment, in particular to a clamping device of a grinding machine. Background Art

[0002] A grinder is a tool that uses a grinding tool to grind a workpiece to obtain the corresponding shape, size and precision. The part is fixed on a clamping device and then ground through a mold, which requires the clamping device to have good fixing ability. In the prior art, the widely used clamps are bench vises (vice) and its various improved models and variants. The bench vise clamps the workpiece through the double-sided bite force of the fixed jaw and the movable jaw to perform various processing operations. In this actual operation process, due to the uncertainty of the shape of the part, when fixing the circular part, the sliding plate and the fixed plate are tangent to the surface of the circular part, which results in a small fixing area and poor fixing effect. Utility Model Content

[0003] In view of this, the utility model provides a clamping device of a grinder, which can push the connecting plate forward through the output end of the cylinder, and the connecting plate drives the clamping assembly to move forward. When the clamping assembly contacts the material to be clamped, the second clamping block on the clamping assembly rotates around the second limit rod according to the shape of the clamped material. When the second clamping block is rotated by a certain angle and still cannot completely clamp and fix the material, the first clamping block will rotate along the first limit rod until it fits with the surface of the clamped material to complete the clamping and fixing of the required material. The serrations on the second clamping block can increase the friction between the object and the clamping assembly to prevent the material from slipping during grinding and causing unnecessary danger. The limit cavities in the limit blocks arranged at both ends of the cylinder can limit the limit rod to prevent the connecting plate from deviating to one side when driving the clamping assembly to clamp the material, causing the connection position between the output end of the cylinder and the connecting plate to break, causing unnecessary danger.

[0006] A first limiting rod is provided in the first arc-shaped groove, and the first limiting rod is used to limit the first clamping block. A first clamping block is provided in the first arc-shaped groove, and the first clamping block is used to connect the second clamping block and clamp the material.

[0008] The second clamping block is connected with a plurality of saw teeth, which are used to enable the second clamping block to better clamp the material. The pushing component includes a cylinder, which is used to push the connecting plate to move, and the cylinder is connected to the operating table.

[0009] Limit blocks are symmetrically provided on both sides of the cylinder, and a limit cavity is provided in the limit block. The limit cavity is used to limit the limit rod. A limit rod is slidably provided in the limit cavity. The limit rod is used to connect the connecting plate and limit the connecting plate to prevent the connecting plate from deviating to one side when the clamping assembly clamps the material, so that the connection position between the cylinder output end and the connecting plate is broken, causing unnecessary danger. The cylinder output end is connected to the connecting plate, and the limit rod is connected to the connecting plate.
