DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-6 A precision hardware appearance inspection device comprises a base 1, an upper end of the base 1 is fixedly connected to an L-shaped support frame 11, and a measuring component 12 is arranged at one end of the L-shaped support frame 11. In this embodiment, the measuring component 12 is a screw micrometer, and the measuring component 12 is used to measure the size of the hardware. The measuring component 12 is fixedly connected to the L-shaped support frame 11 through a connecting mechanism 2. In the utility model, the connecting mechanism 2 is used to facilitate the installation and disassembly of the measuring component 12;

[0025] The upper end of the base 1 is also provided with a clamping mechanism 3 for fixing hardware. In the utility model, the clamping mechanism 3 can ensure that the hardware remains fixed and stable during the measurement process, thereby effectively avoiding measurement errors caused by movement or vibration of the hardware.

[0026] Furthermore, the connecting mechanism 2 includes two semicircular rings 21, one of the semicircular rings 21 is fixedly connected to the L-shaped support frame 11, and the two semicircular rings 21 are both provided with T-shaped ring grooves 22, and the two T-shaped ring grooves 22 are both slidably connected with locking members 23. In the utility model, when fixing the measuring component 12, the two semicircular rings 21 are firstly docked to ensure that they are tightly matched, and then, the locking members 23 are rotated so that the two locking members 23 are respectively inserted into the semicircular rings 21 of each other through the T-shaped ring grooves 22 to form a locked state. At this time, the two locking members 23 are clamped to each other inside the T-shaped ring grooves 22, thereby fixing the measuring component 12. Of course, in order to ensure the clamping force, a rubber pad can also be provided on the inner side of the semicircular ring 21 to enhance the holding force of the measuring component 12.

[0027] Furthermore, the locking piece 23 is a T-shaped snap ring, and a spring rod assembly 24 is movably inserted on the locking piece 23. A positioning hole 25 is provided at the upper end of the T-shaped ring groove 22. The spring rod assembly 24 and the positioning hole 25 are mutually engaged. In the utility model, when the T-shaped snap ring 23 is rotated and locked, the spring rod assembly 24 is inserted into the positioning hole 25 under the action of the spring, thereby further ensuring that the T-shaped snap ring 23 will not rotate during use, thereby enhancing the fixing stability of the measuring component 12. When the detection component 12 needs to be disassembled, the spring rod assembly 24 is pulled to separate it from the positioning hole 25, and then the locking piece 23 is rotated to disengage the two locking pieces 23 from each other's semicircular ring 21, so that the measuring component 12 can be taken out.

[0028] Among them, the clamping mechanism 3 includes a fixed frame 31, the bottom of the fixed frame 31 is rotatably connected with a rotating shaft 32, one end of the rotating shaft 32 is fixedly connected with a gear 33, and two racks 34 are slidably connected to the fixed frame 31, the racks 34 are meshed with the gears 33, and one end of the two racks 34 is fixedly connected with a clamping block 35. In this embodiment, a placement plate is also provided in the fixed frame 31, and the placement plate is used to hold hardware. In the utility model, the rotating gear 33 drives the rack 34 to move, and then drives the clamping blocks 35 to move toward each other, thereby clamping the hardware to prevent the hardware from moving during the detection process, resulting in errors in size detection, and thus affecting product quality and performance.

[0029] In addition, a torsion spring 36 is provided on the surface of the rotating shaft 32, and the two ends of the torsion spring 36 are fixedly connected to the lower end of the gear 33 and the bottom of the fixed frame 31 respectively, and one end of the rack 34 is fixedly connected to a pressing rod 37. In the utility model, the elastic force of the torsion spring 36 drives the gear 33 to rotate, and then drives the rack 34 to move, so that the hardware can be quickly locked. When the hardware is unlocked, the rack 34 is moved by pressing the pressing rod 37, and then the clamping block 35 is moved, thereby unlocking the hardware, thereby reducing the operation time and labor intensity and improving work efficiency.

[0030] In addition, one side of the clamping block 35 is a V-shaped structure, and scales 38 are provided on the surfaces of the upper ends of the rack 34 and the pressing rod 37. In the utility model, one side of the clamping block 35 is a V-shaped structure. This design makes it easy to clamp hardware of different diameters, thereby improving versatility and applicability. When the clamping block 35 clamps the hardware, the diameter size of the hardware can be easily read through the scales 38 provided on the surfaces of the rack 34 and the pressing rod 37.

[0031] Working method: When working, the pressing rod 37 is pressed to open the clamping block 35, and then the elastic force of the torsion spring 36 drives the gear 33 to rotate, and then drives the rack 34 to move, so as to quickly complete the locking of the hardware. When the height size of the hardware is measured by the measuring component 12, when the clamping block 35 clamps the hardware, the diameter size of the hardware can be easily read through the scales 38 set on the surface of the rack 34 and the pressing rod 37. When fixing the measuring component 12, firstly dock the semicircular connecting ring 1 21 with the semicircular connecting ring 22 to ensure that they are tightly matched, and then rotate the T-shaped snap ring 1 24 and the T-shaped snap ring 25 so that their T-shaped snap ring 1 24 and the T-shaped snap ring 25 are respectively inserted through the T-shaped ring groove 22 and form a locking state. At this time, the T-shaped snap ring 1 24 and the T-shaped snap ring 25 are in the T-shaped ring groove. 22 are clamped together inside to fix the measuring component 12. Subsequently, the locking mechanism 26 T-shaped snap ring 1 24 and T-shaped snap ring 25 are used to prevent the T-shaped snap ring 1 24 and T-shaped snap ring 25 from rotating during use. When the T-shaped snap ring 1 24 and T-shaped snap ring 25 rotate, when the insertion rod 262 moves to the top of the fixing hole, the elastic force of the spring 263 pushes the insertion rod 262 to be smoothly inserted into the fixing hole for plugging, thereby fixing the T-shaped snap ring 1 24 and T-shaped snap ring 25 to ensure that the measuring component 12 is stably connected to the L-shaped support frame 11. When the measuring component 12 needs to be disassembled, the insertion rod 262 is pulled out of the fixing hole to release the locking state of the T-shaped snap ring 1 24 and T-shaped snap ring 25, and then the T-shaped snap ring 1 24 and T-shaped snap ring 25 are rotated to complete the disassembly operation of the measuring component 12.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
