Description

Technical Field

[0001] The utility model belongs to the technical field of steel material analysis, and in particular relates to a sample clamp used for a metal in-situ analyzer. Background Art

[0002] The metal in-situ analyzer is a device for quantitative analysis of the composition and state of metal materials. The analyzed materials include ingots and other metallurgical products. The equipment fixes the sample with a fixture. Under the set program, the fixture is moved on the working panel through a robot linkage to achieve continuous scanning and analysis of the sample surface.

[0003] The existing clamps for the manipulator linkage of metal in-situ analyzers are two parallel metal plates with bolt holes at both ends. The two metal plates are connected by two long bolts, and the two long bolts are adjusted to clamp the analysis samples of different sizes. The existing sample clamps have the following problems: (1) High requirements for sample shape: Since the clamp clamps the sample by two parallel metal plates, the parallelism of the sample is required to be high, otherwise it is easy to be clamped unstable, and relative movement occurs during the operation of the manipulator, affecting the continuous scanning analysis results; (2) Time-consuming adjustment: Due to the different sizes of samples, when switching samples with large size differences during use, it is necessary to repeatedly rotate the bolts at both ends to adjust the clamp, which is time-consuming; (3) The sample is not clamped flat: When fixing the sample, manually adjusting the two bolts will cause one side of the sample to tilt and be uneven due to different forces, which will affect the sample excitation effect during the scanning process, and thus affect the accuracy of the analysis results. Summary of the invention

[0004] In view of the problems existing in the prior art, the utility model provides a sample clamp for a metal in-situ analyzer, which can reduce the requirements on the sample shape, facilitate the switching of samples of different sizes, and facilitate adjustment and use, thereby avoiding the problem of uneven clamping that affects the experimental results; it uses push-pull rods for clamping, does not generate torque, and avoids the situation where one side of the sample is warped and uneven.

[0005] The utility model is implemented as follows: a sample fixture for a metal in-situ analyzer comprises a rectangular outer frame, the rectangular outer frame encloses a placement space for placing a sample, a plate on one side of the rectangular outer frame is a clamping plate, and a plate on the side corresponding to the clamping plate is a mounting plate;

[0007] A locking member for locking the position of the push-pull rod is arranged in the mounting plate at the position where the push-pull rod passes through, along a direction perpendicular to the axial direction of the push-pull rod.

[0008] Furthermore, ball screws are arranged at the four corners of the rectangular outer frame, and the steel ball ends of the ball screws penetrate the rectangular outer frame and are supported on the working panel of the analyzer. The arranged ball screws can not only fasten the plate, but also enable the fixture to drive the sample to move on the working panel of the analyzer, thereby realizing continuous scanning and analysis of the sample surface, and saving more manpower.

[0009] Furthermore, the inner surface of the clamping plate is provided with a first clamping groove, and the clamping surface of the clamping block is provided with a second clamping groove. The first clamping groove and the second clamping groove increase the contact area between the clamping plate and the clamping block and the target object, thereby enhancing the clamping stability.

[0010] Furthermore, the first clamping groove and the second clamping groove are both V-shaped grooves, and the opening directions of the first clamping groove and the second clamping groove are arranged opposite to each other. The first clamping groove and the second clamping groove are both V-shaped grooves, which can meet the clamping requirements of the columnar sample, not only ensuring the stability and safety of the columnar sample during the clamping process, but also making it difficult for the columnar sample to be displaced or damaged during the clamping process.

[0012] Furthermore, the clamping plate is provided with a mounting hole for connecting to the manipulator along the thickness of the plate.

[0013] Furthermore, the clamping block is a trapezoidal block, and the short side of the clamping block faces the clamping plate. The clamping block adopts a trapezoidal structure, which has better stability, especially when it needs to withstand vertical or lateral pressure. It can disperse the pressure, improve the overall stability, and prevent slippage or loosening during the clamping process; it can better distribute the clamping force evenly to the surface of the clamped object, reducing damage or deformation caused by concentrated pressure.

[0014] Furthermore, a hand-held portion is provided at the end of the push-pull rod extending outward.

[0015] The utility model has the following advantages and technical effects: due to the adoption of the above technical scheme, the requirements on the shape of the sample are reduced, it is easy to switch samples of different sizes, and it is convenient to adjust and use, thus avoiding the problem of uneven clamping that affects the experimental results; by clamping with a push-pull rod, no torque is generated, thus avoiding the situation where one side of the sample is tilted and uneven.
