Description

Technical Field

[0001] The present invention relates to the technical field of material hardness detection, and in particular to a material hardness detection device based on building intelligence. Background Art

[0002] Hardness tester is a special instrument used to measure the surface hardness of materials. Hardness tester is divided into two types: desktop hardness tester and portable hardness tester. Desktop hardness tester is mainly used in laboratories and has the advantage of high precision. Portable hardness tester is suitable for installed machinery or permanent assembly parts and is easy to carry. Portable hardness tester integrates portable hardness testers such as Leeb, Brinell, Rockwell, etc., and can realize the free conversion of 7 different hardness values, eliminating the cumbersome procedure of manual hardness table search in the past, and realizing the characteristics of true intelligence and portability. When testing the hardness of high-strength materials, when the height difference between the upper and lower surfaces of the sample is greater than the distance between the indenter and the sample surface (usually When the sample is about 0.5mm, the indenter may be hit, which may cause damage to the indenter during measurement and affect the detection of material hardness. In the prior art, a sample flattener is used to solve the problem of damage to the indenter due to collision of the sample surface. However, in the prior art, the sample is first placed on a flattener and flattened, and then the sample is moved to a hardness tester for detection. Only then can the sample be tested. Such operation is cumbersome and reduces the work efficiency of sample detection. At the same time, when transferring the sample, the flattened sample is easily mixed with the unflattened sample, increasing the risk of collision damage to the indenter. Therefore, a material hardness detection device based on building intelligence is proposed to solve the above problems. Summary of the invention

[0032] In the present invention, the unlocking member includes a push rod 17 arranged on the outer wall of the movable rod 27, and an unlocking groove 30 is provided on the side of the rectangular frame 11 to cooperate with the push rod 17. The unlocking groove 30 is composed of an inclined groove and parallel grooves arranged at both ends of the inclined groove, wherein the inclined groove can enable the push rod 17 to move upward, thereby disengaging the clamping head 28 from the clamping slot 29, thereby realizing the unlocking of the rotating shaft 4.

[0033] In the present invention, the protective component includes a rectangular box 9 symmetrically arranged on the hardness testing device body 1, a baffle 12 slidably arranged in the rectangular box 9, and a plurality of tension springs 13 arranged between the baffle 12 and the rectangular box 9, and the baffle 12 is made of a transparent material to facilitate observation of the sample testing situation in the hardness testing device body 1; a connecting rod 8 is provided on the top of the baffle 12, and a strip opening 14 is provided on the top surface of the shell of the hardness testing device body 1 to cooperate with the connecting rod 8, and the top of the connecting rod 8 is movably penetrated to the top of the strip opening 14, a pulley 7 is symmetrically rotated on the top surface of the shell of the hardness testing device body 1, and one end of the traction rope 10 passes through the pulley 7 and is fixed to the connecting rod 8, and the traction rope 10 passes through the pulley 7 close to the side of the other traction rope 10, so as to facilitate the two baffles 12 to contact each other.

[0034] Working principle: When the present invention is used, the sample is first placed on the loading platform of the hardness testing device body 1, and then the electric push rod 25 is turned on, and the rectangular frame 11 is moved by the extension of the telescopic end of the electric push rod 25, and the movement of the rectangular frame 11 is divided into two processes:

[0035] Process 1: After the telescopic end of the electric push rod 25 moves to a certain distance, that is, point A, at this time, the movable block 21 moves with the rectangular frame 11 under the action of the extrusion spring 26, thereby driving the connecting rod 2 19 and the bar-shaped toothed plate 1 20 to move, and further driving the gear 2 15 to rotate. The rotation of the gear 2 15 drives the connecting shaft 18 to rotate, and then drives the winding wheel 24 to rotate, so that the traction rope 10 is wound around the winding wheel 24, thereby pulling the baffle 12 to move relatively. When the telescopic end of the electric push rod 25 moves to point A, the two baffles 12 contact each other, which is convenient for protecting the area of ​​the front end surface of the hardness testing equipment body 1; then, under the action of the baffle 12, the movable block 21, the bar-shaped toothed plate 1 20, etc. are all in a relatively static state;

[0036] Process 2: After the two baffles 12 contact each other, the push rod 17 enters the parallel groove at the bottom of the unlocking groove 30, and as the telescopic end of the electric push rod 25 continues to move to the end of the telescopic end of the electric push rod 25, at this time, the rectangular frame 11 moves first to make the push rod 17 move along the inclined groove of the unlocking groove 30, so that the push rod 17 moves upward, thereby driving the movable rod 27 and the clamping head 28 to move upward, but when the push rod 17 moves from the bottom of the inclined groove of the unlocking groove 30 to the top, the clamping head 28 is disengaged from the clamping groove 29, and the rotating shaft 4 is unlocked; at the same time, the push rod 17 moves to the parallel groove at the top of the unlocking groove 30, and the bar-shaped tooth plate 22 is meshed with the gear 1 6;

[0037] Then the rectangular frame 11 continues to move, which will drive the movement of the bar-shaped toothed plate 22, thereby driving the gear 1 6 to rotate, and further driving the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the support plate 2 to rotate, thereby driving the flattening device body 3 to rotate. At the same time, when the telescopic end of the electric push rod 25 moves to the end, the flattening device body 3 rotates 180°. At this time, the flattening device body 3 is located directly above the sample, and then the sample is flattened by the flattening device body 3 to avoid the unevenness of the sample causing the pressure head of the hardness testing device body 1 to be damaged, thereby facilitating the protection of the pressure head of the hardness testing device body 1.

[0038] Then, the sample is flattened by the flattening device body 3. After the sample is flattened, the telescopic end of the electric push rod 25 is controlled to be retracted to point A. At this time, the flattening device body 3 is first rotated and reset. After the flattening device body 3 rotates 180°, the bar-shaped tooth plate 22 is disengaged from the gear 1 6. Then, the rectangular frame 11 continues to move to make the push rod 17 move out of the unlocking groove 30. Then, the clamping head 28 is inserted into the clamping groove 29 under the action of the reset spring 31 to fix the rotating shaft 4.

[0039] Finally, the hardness of the sample is tested by the hardness testing device body 1 (which is the prior art). When the hardness of the sample is tested, the debris splashing and hitting the front end of the hardness testing device body 1 will be blocked by the baffle 12, thereby facilitating the protection of the operator standing at the front end of the hardness testing device body 1.

[0040] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
