Description

Technical Field

[0001] The utility model relates to the technical field of alloy rod bending detection, in particular to a bending measuring device for a steel-bonded cemented carbide rod. Background Art

[0002] A Chinese utility model patent application numbered CN202221943739.2 discloses a device for measuring the curvature of a metal bar. The device comprises a measuring rod disposed below a crossbeam of the measuring device, and a standard rod disposed below the crossbeam of the measuring device; an adjustment frame disposed below the crossbeam of the measuring device, the adjustment frame having guide rods and adjustment rods disposed therein, and a metal bar disposed below the adjustment frame; and a clamping plate sleeved on the surfaces of the guide rod and the adjustment rod.

[0003] In this device, a clamping plate is used to fix the position of the rod, and then the curvature of the rod is measured by a measuring instrument. However, there is no fixed seat structure in the device, so the method of use is to hold the device for detection. However, if the measurement is handheld, the force exerted on each measuring rod may be different due to the strength of the measurer or the weight of the device, so the measurement result may be inaccurate. Utility Model Content

[0004] The technical problem to be solved by the present invention is that the existing rod curvature measuring device is a handheld measuring method, and the test result may be inaccurate due to the strength of the tester or the weight of the device during the test.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is a steel-bonded carbide rod bending measurement device, including two support structures, the support structure includes a base plate, a limit frame is fixed on the upper side of the base plate, a sliding frame is provided on the inner side of the limit frame for sliding, a lower clamp is fixed on the top of the sliding frame, an upper clamp is hinged at one end of the lower clamp, a plurality of balls are provided on one side of the upper clamp and the lower clamp for uniform rotation, a connecting rod is fixed on the top of the upper clamp in the two support structures, a liquid level is hinged between the sliding frames in the two support structures, a support frame is fixed on the upper side of a base plate, and a reference measuring rod is fixed on the top of the support frame and the top of the connecting rod.

[0006] As a further solution of the present invention: a threaded hole is provided on the lower side of the sliding frame, a hollow area is provided on the upper side of the base plate and the bottom of the limit frame, an adjusting wheel is rotatably provided in the hollow area, a screw rod rotatably connected to the threaded hole is fixed on the upper side of the adjusting wheel, and rotating the adjusting wheel can control the screw rod to drive the sliding frame to move.

[0007] As a further solution of the present invention, a buckle is rotatably provided at one end of the upper clamp body, and a buckle groove is provided at one end of the lower clamp body at the buckle, so as to facilitate fixing the upper clamp body and the lower clamp body.

[0008] As a further solution of the present invention: the contact surface at the hinge between the liquid level and the sliding frame is a curved surface. When the two sliding frames are of different heights, they will not be blocked by the liquid level. The lower side of the adjusting wheel and the lower side of the hollow area are both curved surfaces. When the two sliding frames are of different heights, tilting space can be reserved for the adjusting wheel.

[0009] As a further solution of the present invention: a rod is sandwiched between the upper clamping body and the lower clamping body.

[0010] Compared with the prior art, the advantages of the present invention are as follows: the present patent adds a sliding frame and a liquid level structure, and uses the liquid level to observe whether the two sliding frames are located in the horizontal plane to determine whether the forces acting on each position of the rod body are the same. The sliding frame can be driven for fine-tuning by rotating the screw rod, and a ball structure is added to facilitate the rotation of the rod body between the upper clamp body and the lower clamp body, thereby facilitating the measurement of curvature at different positions.
