Description

Technical Field

[0001] The utility model belongs to the technical field of metal hardness detection, and particularly relates to an adjustable fixing mechanism for metal hardness detection. Background Art

[0002] Hardness is one of the most commonly used indicators for evaluating the mechanical properties of metal materials. The essence of hardness is the ability of a material to resist the intrusion of another harder material. For the material being tested, hardness represents the comprehensive performance of multiple physical quantities such as elasticity, plasticity, strength, toughness and wear resistance under a certain indenter and test force. In the detection of metals, metal hardness testers are generally used for detection.

[0003] The existing metal hardness tester workbench does not have a structure for adjusting and fixing metal parts. Therefore, in actual operation, the metal parts can only be placed flat on the workbench. During the placement process, the position of the metal parts needs to be manually adjusted to ensure that the metal parts are aligned with the detection head of the tester and until the two are in contact for subsequent testing. This method is extremely inconvenient to operate, and once the metal parts have an irregular structure, alignment is even more difficult. Therefore, we need to upgrade and transform based on the existing technology. Utility Model Content

[0025] like Figure 1 - Figure 5 As shown, the present embodiment provides an adjustable fixing mechanism for metal hardness testing, including a device body 1, which includes a placement table 2, a detection head 3 is installed on the placement table 2, and support rods 6 are provided on the left and right sides of the placement table 2, a detection table 4 is provided below the detection head 3, a mounting seat 7 is provided above the support rod 6, a knob 8 is rotatably installed in the mounting seat 7, a threaded rod 10 is screwed in the knob 8, a connecting plate 11 is provided at the front end of the threaded rod 10, an extension buckle 13 is provided at the front end of the connecting plate 11, a hinge 14 is rotatably installed in the extension buckle 13, one side of the hinge 14 is connected to a splint 15, and a splint 2 16 is rotatably installed in the hinge 14.

[0026] Preferably, anti-slip grooves 9 are provided in the knob 8, and there are multiple groups of anti-slip grooves 9. By providing the anti-slip grooves 9, the user can avoid the situation where the hand slips and it is difficult to twist the knob 8 when the user turns it. The rear end of the threaded rod 10 is connected to a limit plate 12, and the limit plate 12 is fixedly connected to the threaded rod 10 and the width of the limit plate 12 is greater than the width of the threaded rod 10 itself. By setting the limit plate 12, the threaded rod 10 can be limited to avoid the threaded rod 10 falling off the mounting seat 7 in the knob 8 during movement, thereby ensuring the safety of the threaded rod 10. The rear ends of the splint 15 and the splint 2 16 are fixedly connected to the spring 19, and one end of the spring 19 is fixedly connected to the connecting plate 11. By setting the spring 19, the intimacy and connectivity between the devices are increased.

[0027] Preferably, elastic pads 17 are fixedly installed on the front end walls of splint 15 and splint 2 16. By providing the elastic pads 17, the buffering force of splint 15 and splint 2 16 is increased to avoid squeezing and wear of the test piece during use. Anti-skid plates 18 are installed in the elastic pads 17, and multiple groups of anti-skid plates 18 are provided. By providing the anti-skid plates 18, the anti-slip property of the elastic pads 17 is increased, ensuring the safety of the elastic pads 17 during use.

[0028] The use principle and use process of the present invention are as follows: when in use, the test piece that needs hardness test is placed on the test table 4, and the user turns the knob 8 by hand. During the rotation of the knob 8, the threaded rod 10 is driven to move in the knob 8 and the mounting seat 7, and during the movement, the connecting plate 11 is driven to approach the test piece. When the connecting plate 11 moves, it drives the first clamping plate 15 and the second clamping plate 16 to move accordingly. When the first clamping plate 15 and the second clamping plate 16 move, they drive the elastic pad 17 and the anti-slip plate 18 to move accordingly, until the elastic pad 17 and the anti-slip plate 18 are in close contact with the test piece. During the close contact process, the spring 19 is forced to shrink and is in an extruded state. At this time, the metal piece is clamped, and metal pieces of different sizes can be clamped and limited, which improves the application range of the device, makes it convenient for users to test metal pieces, and ensures that the metal To ensure the safety of parts during inspection, when it is necessary to clamp heterogeneous metal parts, the user turns the knob 8 by hand. During the rotation of the knob 8, the threaded rod 10 is driven to move in the knob 8 and the mounting seat 7, and during the movement, the connecting plate 11 is driven to approach the inspection part. When the connecting plate 11 moves, it drives the splint 15 and the splint 2 16 to move accordingly. When the splint 15 and the splint 2 16 move, they drive the elastic pad 17 and the anti-slip plate 18 to move accordingly until the elastic pad 17 and the anti-slip plate 18 are in close contact with the inspection part. During the close contact process, the splint 15 and the splint 2 16 are rotated under force, and during the rotation process, the spring 19 is contracted under force and is in an extruded state. At this time, the metal parts are clamped, and heterogeneous metal parts can be clamped and fixed, which increases the practicality and convenience of the device and improves the flexibility of the workbench.
