Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to an adjustable fastening device for hardware processing. Background Art

[0002] Hardware processing is the process of processing raw materials into various parts according to customer drawings or samples using lathes, milling machines, drilling machines, polishing machines and other machines, such as screws, motor shafts, model car parts, fishing gear accessories, speaker product casings, mobile power casings, etc. When processing hardware, it is necessary to tighten and clamp it to facilitate its processing.

[0003] In the prior art, conventional fastening devices for hardware processing mostly use two clamps for clamping. When it is necessary to clamp a workpiece with a different shape, the clamping area is small, resulting in unstable clamping. At the same time, during the clamping process, the clamping pressure cannot be monitored, and there are problems such as small clamping force causing the workpiece to fall, and large clamping force causing damage to the workpiece. In addition, the fastening device has a single function and cannot collect the dust generated during the processing, so it has low practicality. Utility Model Content

[0021] Specifically, the prompt mechanism 3 includes a pressure sensor 301 and an audible and visual alarm 302. The pressure sensor 301 is rectangular and fixedly installed at the four corners of the right side of the vertical plate 2. The right side of the pressure sensor 301 is fixedly connected to the left side of the fixed splint 4. The audible and visual alarm 302 is installed on the right side of the vertical plate 2.

[0022] In this embodiment, the pressure sensor 301 monitors the manual pressure of the fixed clamping plate 4 and timely monitors the manual clamping force of the workpiece. When the clamping force of the workpiece is greater than or lower than the set value, the sound and light alarm 302 alarms to remind the staff.

[0023] Specifically, the driving mechanism 5 includes a manual linear module 501, a handle 502 and a rectangular opening 503. The manual linear module 501 is fixedly installed between the left and right side walls of the base box 1, and the handle 502 is fixedly installed on the left end of the screw rod of the manual linear module 501. The handle 502 is arranged on the left side of the left side wall of the base box 1. The upper surface of the slide of the manual linear module 501 is fixedly connected to the lower surface of the movable splint 6. The upper side wall of the base box 1 corresponding to the slide of the manual linear module 501 and the front and rear edges of the upper side wall of the base box 1 are provided with rectangular openings 503.

[0024] In this embodiment, the handle 502 rotates the screw of the manual linear module 501, so that the slide of the manual linear module 501 drives the movable clamping plate 6 to move left and right. The rectangular opening 503 meets the left and right requirements of the manual linear module 501 slide, and the front and rear rectangular openings 503 meet the dust collection function.

[0025] Specifically, the outer surface of the slide of the manual linear module 501 is a rectangular structure, and the front and rear side surfaces of the slide of the manual linear module 501 are movably fitted with the front and rear inner walls of the middle rectangular opening 503 .

[0026] In this embodiment, the slide of the manual linear module 501 moves left and right along the front and rear inner walls of the middle rectangular opening 503, so that the slide of the manual linear module 501 can stably drive the moving clamping plate 6 to move left and right.

[0027] Specifically, the clamping mechanism 7 includes a threaded hole 701, a bolt rod 702 and a clamping plate 703.

The bolt rod 702 is installed with threads inside the threaded hole 701, and the clamping plate 703 is fixedly installed on the facing ends of the left and right bolt rods 702.

[0028] In this embodiment, according to the shape and size of the workpiece, a bolt rod 702 is installed in the corresponding threaded holes 701 on the fixed clamp 4 and the movable clamp 6, and the bolt rod 702 moves and retracts in the threaded hole 701, driving the clamping plate 703 to move left and right, so that the workpiece can be clamped and fixed at multiple positions.

[0029] Specifically, the four corners of the lower surface of the bottom box 1 are rectangular and fixed with anti-slip pads 12 .

[0030] In this embodiment, the anti-skid pad 12 makes the bottom box 1 more stable.

[0031] During use, when it is necessary to fix a relatively regular rectangular workpiece, it can be clamped directly through the fixed clamping plate 4 and the movable clamping plate 6. When it is necessary to fix an irregular workpiece, a bolt rod 702 is installed in the corresponding threaded holes 701 on the fixed clamping plate 4 and the movable clamping plate 6 according to the shape and size of the workpiece, and the bolt rod 702 moves and retracts in the threaded hole 701, driving the clamping plate 703 to move left and right. The manual linear module 501 slide in the driving mechanism 5 moves to the left along the front and rear inner walls of the middle rectangular opening 503, so that the manual linear module 501 slide can stably drive the movable clamping plate 6 to move left, and the movable clamping plate 6 drives the right clamping mechanism 7 to move left, so that the left and right clamping mechanisms 7 clamp and fix the workpiece on the left and right sides, thereby meeting the needs of various shapes. The workpieces of the specified specifications are clamped and fixed, and the clamping is more firm and stable. The manual pressure of the fixed clamping plate 4 is monitored by the pressure sensor 301 in the prompt mechanism 3, and the manual clamping force of the workpiece is monitored in time. When the clamping force of the workpiece is greater than and lower than the set value, the sound and light alarm 302 alarms to remind the staff, making it safer to use. The bottom box 1 is connected to the external exhaust fan through the air pipe joint 10 to exhaust air, and a negative pressure is formed in the bottom box 1, so that dust enters the bottom box 1 through the rectangular opening 503 and then enters the drawer 8. The dust is filtered and collected by the filter net 9, so that the dust generated when the workpiece is moved can be collected, which is more environmentally friendly. The hidden lock 11 is opened and the drawer 8 is taken out to centrally process the dust.

[0032] In summary, the adjustable fastening device for hardware processing can install the corresponding clamping mechanism 7 according to the shape and size of the workpiece, so as to meet the clamping and fixation of workpieces of various shapes and specifications, and the clamping is more firm and stable. It can prompt the clamping force of the workpiece to make the clamping force of the workpiece moderate, and can collect the dust generated when the workpiece is clamped, making it more environmentally friendly to use.
