Description

Technical Field

[0001] The utility model relates to the field of steel plate rolling, in particular to a sample block centering device. Background Art

[0002] In order to ensure the quality of steel plate rolling production, each batch needs to be sampled and then the strength data of the sample block (long strip structure) needs to be tested to see if it is qualified. The sample block must be processed as required before testing. One of the steps is notching, which must be done in the middle of the sample block with an error of plus or minus 0.5 mm. The current operation procedure is to first place the sample block on the notching machine workbench, then manually measure the position with a steel ruler to see if it is centered, and then manually correct it, which is inefficient and has low accuracy. Summary of the invention

[0003] In view of the above inconvenience, the utility model provides a centering device capable of quickly finding the center line of the sample block. The specific scheme is as follows:

[0004] A sample block centering device is used to assist a carving knife in making a center line mark on the middle of a sample block, comprising:

[0005] The centering plate has a centering mark at the midpoint of its length;

[0006] The centering frame is provided with:

[0007] A clamping unit, which includes a driving mechanism and two shifting blocks;

[0008] The two shift blocks are symmetrically located on both sides of the centering mark;

[0009] The driving mechanism controls the two shifting blocks to synchronously clamp the sample block so that the midpoint of the sample block coincides with the centering mark.

[0010] Furthermore, the driving mechanism comprises:

[0011] A bidirectional screw rod is arranged along the length direction of the centering frame plate, and its midpoint is aligned with the centering mark;

[0012] Both shift blocks are provided with screw holes, which are respectively threadedly connected with the positive and negative thread surfaces in the bidirectional screw. A slot is provided in the centering frame plate, and the slot is parallel to the bidirectional screw. The two shift blocks are respectively engaged with the slot. When the bidirectional screw rotates, the slot limits the shift block to follow the rotation of the bidirectional screw, so that the two shift blocks make synchronous relative displacement along the length direction of the bidirectional screw.

[0013] Furthermore, a crank is provided at either end of the bidirectional screw rod to drive the bidirectional screw rod to rotate.

[0014] Furthermore, both ends of the bidirectional screw are respectively sleeved with shaft seats fixedly connected to the centering frame plate, and the two shaft seats are symmetrically arranged on the centering mark line.

[0015] Furthermore, the slot is a through slot recessed from both sides of the centering frame plate in the length direction to the middle thereof, and the middle portion of the shifting block is inserted into the through slot on the side thereof.

[0016] Compared with the prior art, the advantages of the utility model are as follows:

[0017] 1. The utility model has the function of quickly finding the midpoint of the sample block, which provides convenience for the detection operation of the sample block.

[0018] 2. The utility model has the advantage of simple operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments.

[0025] Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the utility model.

[0026] In the description of the utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to has a specific orientation, is constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances. Example
