Technical Field

The utility model relates to the technical field of clamps, in particular to a sealing clamp and a clamping device.

Background

A clamp is a device or tool for securing, clamping and supporting a workpiece. The clamp plays an important role in manufacturing, can improve working efficiency, ensure product quality and safety, and simplify manufacturing process. Different types of clamps include manual clamps, hydraulic clamps, pneumatic clamps, mechanical clamps, etc., which are widely used in various fields such as machining, automotive manufacturing, electronics assembly, aerospace, etc.

During use of the clamp, the clamping area of the clamp is also contacted with the liquid and reacts, resulting in the formation of a metal layer (e.g., copper, tin, nickel, etc.) on the surface of the area. After long-term use, the metal layers can accumulate to form metal blocks, thereby affecting the stability of the clamp for clamping the piece to be clamped.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the related art, in the electroplating or electroless plating process, a clamp is used to clamp a workpiece to be clamped and immerse the workpiece in a liquid, so that the workpiece to be clamped reacts with the liquid. During use of the clamp, the clamping area of the clamp is also contacted with the liquid and reacts, resulting in the formation of a metal layer (e.g., copper, tin, nickel, etc.) on the surface of the area. After long-term use, the metal layers can accumulate to form metal blocks, thereby affecting the stability of the clamp for clamping the piece to be clamped.

In order to solve the above technical problems, an embodiment of the present utility model is described below with reference to fig. 1 to 3.

According to an embodiment of the present utility model, in one aspect, as shown in fig. 1 to 3, there is provided a sealing clamp comprising a first clamping arm 1, a second clamping arm 3 and two sets of flexible sealing sleeves 5.

As the second clamping arm 3 continues to rotate towards the first clamping arm 1, the two groups of flexible sealing sleeves 5 are extruded to deform, so that the end surfaces of the two groups of flexible sealing sleeves 5 are sealed with the outer surface of the piece to be clamped, and meanwhile, the first clamping block 2 and the second clamping block 4 respectively clamp the opposite surfaces of the piece to be clamped and are sealed by the two groups of flexible sealing sleeves 5 and the piece to be clamped. In this case, the sealing jig can safely immerse the workpiece to be clamped in the liquid, thereby avoiding the first clamping block 2 and the second clamping block 4 from contacting the liquid and causing adverse reaction, preventing the metal layer or the metal block from being formed on the clamping surfaces of the first clamping block 2 and the second clamping block 4, and ensuring the sealing jig to stably clamp the workpiece to be clamped.

In the process of clamping the workpiece to be clamped, since the height of the limiting piece 12 is higher than that of the first clamping block 2, when the workpiece to be clamped stretches into the space between the first clamping arm 1 and the second clamping arm 3, the part, higher than the first clamping block 2, of the limiting piece 12 limits the stretching length of the workpiece to be clamped, so that the position of the workpiece to be clamped can be accurately clamped by the first clamping block 2 and the second clamping block 4.

Specifically, protective sleeves 13 may be disposed on the first clamping arm 1 and the second clamping arm 3 to protect the first clamping arm 1 and the second clamping arm 3 from reacting with the liquid contact.

The working principle of the sealing clamp in this embodiment is described as follows:

1) Clamping the workpiece to be clamped from a loosening state to a clamping state:

The external force applied to the handle 6 towards the direction of the first clamping arm 1 causes the handle 6 to rotate towards the direction of the first clamping arm 1 and drives the second clamping arm 3 to rotate towards the direction of the first clamping arm 1, and as the end surfaces of each group of flexible sealing sleeves 5 correspondingly protrude out of the clamping surfaces of the first clamping block 2 and the second clamping block 4, the end surfaces of the two groups of flexible sealing sleeves 5 are firstly contacted with the opposite surfaces of the workpiece to be clamped respectively, and then the first clamping block 2 and the second clamping block 4 are not contacted with the workpiece to be clamped. As the second clamping arm 3 continues to rotate towards the first clamping arm 1, the two groups of flexible sealing sleeves 5 are extruded to deform, so that the end surfaces of the two groups of flexible sealing sleeves 5 are sealed with the outer surface of the piece to be clamped, and meanwhile, the first clamping block 2 and the second clamping block 4 respectively clamp the opposite surfaces of the piece to be clamped and are sealed by the two groups of flexible sealing sleeves 5 and the piece to be clamped. In this case, the sealing jig can safely immerse the workpiece to be clamped in the liquid, thereby avoiding the first clamping block 2 and the second clamping block 4 from contacting the liquid and causing adverse reaction, preventing the metal layer or the metal block from being formed on the clamping surfaces of the first clamping block 2 and the second clamping block 4, and ensuring the sealing jig to stably clamp the workpiece to be clamped.

The handle 6 is on pivoted in-process passes through connecting piece 9 with effort transfer to slider 7 for slider 7 moves along the length direction of first arm lock 1 towards keeping away from first clamp splice 2, and at the in-process that slider 7 moved, slider 7 need overcome the elastic force of elastic component 8, until sealing jig gets into the clamping state, and at this moment, the other end of connecting piece 9 is close to slider 7, and elastic component 8 jointly applys the elastic force towards first clamp splice 2 direction to slider 7 and connecting piece 9, makes connecting piece 9 exert effort to handle 6 and is used for locking handle 6.

2) From the clamping state to the unclamping state, unclamping the piece to be clamped:

The external force applied to the handle 6 towards the direction far away from the first clamping arm 1 causes the handle 6 to rotate towards the direction far away from the first clamping arm 1, drives the second clamping arm 3 to rotate towards the direction far away from the first clamping arm 1, and the first clamping block 2 and the second clamping block 4 respectively loosen the opposite surfaces of the workpiece to be clamped, and then the end surfaces of the two groups of flexible sealing sleeves 5 are gradually separated from the opposite surfaces of the workpiece to be clamped until the sealing clamp completely loosens the workpiece to be clamped.

In this process, the elastic member 8 applies an elastic force to the slider 7 in the direction toward the first clamping block 2, pushing the slider 7 to move in the direction toward the first clamping block 2, the other end of the connecting member 9 is away from the slider 7, and the connecting member 9 further pushes the handle 6 to rotate, so that the sealing clamp enters a released state.
