Description

Technical Field

[0001] This utility model relates to the field of shaft manufacturing technology, specifically to a machining fixture for shaft structural components. Background Technology

[0002] A hinge, as the name suggests, is an essential shaft used to connect main components of a product, bearing both bending and torque during rotation. Common hinges include: mobile phone hinges (flip or rotating screen phones); laptop hinges; portable DVD hinges; LED desk lamp hinges; LCD display hinges; GPS and other vehicle mount hinges, etc. Existing machining equipment has certain shortcomings in the drilling process of hinge components: the mechanical fixtures used to fix the hinge are inconvenient for securing curved surfaces such as the hinge. This causes the hinge to shift during drilling, resulting in the drilling axis not being on the same plane, affecting subsequent use. Based on the shortcomings of existing technology, this utility model designs a machining fixture for hinge components. Utility Model Content

[0011] As a preferred embodiment of this utility model, the bottom of the workbench is fixedly equipped with four support legs.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. A machining fixture for a rotating shaft structure, through a clamping structure and a support structure, allows the rotating shaft to be placed between two clamping arc plates by hand during machining. Then, driven by a servo motor, its output shaft drives a bidirectional screw to rotate, thereby causing two threaded blocks to move symmetrically in opposite directions on the outer surface of the bidirectional screw. Since the hinge rod connects both ends to the threaded blocks and the lower connecting plate, the hinge rod can pull the lower connecting plates on both sides to slide inside the second slide rail. This allows the clamping arc plates on both sides to initially fix the rotating shaft. Then, by activating the electric cylinder, its telescopic rod drives the second wedge block to slide inside the first slide rail. Since the inclined side of the second wedge block is in contact with the inclined side of the first wedge block, the first wedge block can drive the support arc plate to slide upward, so that it abuts against the rotating shaft. This can fix the rotating shaft through three-sided limiting, thereby avoiding the occurrence of displacement during drilling.

[0014] 2. The machining fixture for this type of rotating shaft structure has a chip collection structure. When drilling holes in the rotating shaft, the micro exhaust fans on both sides are turned on, thereby sucking the chips generated during drilling into the collection frame through the air duct. Then, the collection frame is cleaned by opening the door. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A machining fixture for a rotating shaft structure includes a worktable 1. A clamping structure 2 is provided on the outer surface of the worktable 1, and a support structure 3 is fixedly installed inside the clamping structure 2. The clamping structure 2 includes two second slide rails 21 and two support plates 26. Moving blocks 22 are slidably mounted on the outer surfaces of the two second slide rails 21. A connecting plate 23 is fixedly mounted on one side of each of the two moving blocks 22. Two clamping arc plates 24 are fixedly mounted on one side of each of the two connecting plates 23. An mounting plate 27 is fixedly mounted on one side of the outer surface of one support plate 26. A servo motor 28 is fixedly mounted inside the mounting plate 27. A bidirectional screw 29 is fixedly mounted at one end of the output shaft of the servo motor 28. Threaded blocks 210 are threaded on both sides of the outer surface of the bidirectional screw 29. Two hinged rods 211 are hingedly mounted at the bottom of the two threaded blocks 210. Lower connecting plates 25 are fixedly mounted at the bottom of the two moving blocks 22, and the two lower connecting plates 25 are hingedly connected to the four hinged rods 211. The support structure 3 includes a support arc plate 31, an electric cylinder 33, and a second wedge block 34.

[0023] Please see Figure 2-4The supporting arc plate 31 is slidably connected to the worktable 1, and the second wedge block 34 is fixed to the bottom of the inner cavity of the worktable 1. The second wedge block 34 is fixedly installed at one end of the telescopic rod of the electric cylinder 33, and the second wedge block 34 is slidably connected to the first slide rail 35. A first wedge block 32 is fixedly installed at the bottom of the supporting arc plate 31, and the inclined surface of the first wedge block 32 is in contact with the inclined surface of the second wedge block 34.

[0024] By activating the electric cylinder 33, its telescopic rod drives the second wedge block 34 to slide inside the first slide rail 35. Since the inclined side of the second wedge block 34 is in contact with the inclined side of the first wedge block 32, the first wedge block 32 can drive the supporting arc plate 31 to slide upward, so that it abuts against the rotating shaft.

[0025] Please see Figure 5 Four debris collection structures 4 are fixedly installed on the top of the outer surface of the workbench 1. Each debris collection structure 4 includes a miniature exhaust fan 41. Air ducts 42 are fixedly installed on the top of each miniature exhaust fan 41, and collection frames 43 are fixedly installed on one side of the outer surface of each miniature exhaust fan 41. Opening doors 44 are hinged to one side of the outer surface of each collection frame 43. Four support legs 5 are fixedly installed on the bottom of the workbench 1.

[0026] When drilling holes in the shaft, the miniature exhaust fans 41 on both sides are turned on, so that the debris generated during drilling can be sucked into the collection frame 43 through the air duct 42. Then, the collection frame 43 is cleaned by opening the opening and closing door 44.

[0027] Working principle: When using a machining fixture for a rotating shaft structure, the rotating shaft is first placed between the two clamping arc plates 24 by hand. Then, driven by the servo motor 28, its output shaft drives the bidirectional screw 29 to rotate. This causes the two threaded blocks 210 to move symmetrically in opposite directions on the outer surface of the bidirectional screw 29. Since the hinge rod 211 hinges its two ends to the threaded blocks 210 and the lower connecting plate 25, the hinge rod 211 can pull the two lower connecting plates 25 to slide inside the second slide rail 21. This allows the two clamping arc plates 24 to initially fix the rotating shaft. Subsequently, the shaft is further fixed by... Start the electric cylinder 33, causing its telescopic rod to drive the second wedge block 34 to slide inside the first slide rail 35. Since the inclined side of the second wedge block 34 is in contact with the inclined side of the first wedge block 32, the first wedge block 32 can drive the supporting arc plate 31 to slide upward, so that it abuts against the rotating shaft. Thus, the rotating shaft can be fixed by the three-sided limit, and the rotating shaft can be drilled. When drilling, the micro exhaust fans 41 on both sides are turned on, so that the debris generated during drilling can be sucked into the collection frame 43 through the air duct 42. Then, the collection frame 43 is cleaned by opening the opening and closing door 44.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
