[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] like Figure 1-4 As shown, a hardware processing drilling and fixing fixture includes a carrier plate 1. A placement box 2 is slidably mounted on the upper surface of the carrier plate 1 along its length, and the placement box 2 is detachably connected to the carrier plate 1. The placement box 2 has a fixing mechanism 3 inside that can fix the hardware parts. The upper surface of the carrier plate 1 has a plurality of positioning holes 101 along its length. A push block 201 is mounted on the outer surface of the placement box 2, and the push block 201 has a positioning mechanism 4 inside that engages with the positioning holes 101.

[0023] When in use, the hardware is placed in the placement box 2 and fixed by the fixing mechanism 3. At this time, the positioning mechanism 4 is inserted and engaged with the first positioning hole 101, so that the position of the placement box 2 is fixed, and the first hole can be drilled directly by the drilling machine.

[0024] Next, release the insertion and engagement of the positioning mechanism 4 with the positioning hole 101, and release the fixation of the placement box 2. At this time, the placement box 2 can be slid horizontally on the carrier plate 1 to adjust the position of the hardware. Then, use the insertion and engagement of the positioning mechanism 4 with the second positioning hole 101 to fix the placement box 2 again. At this time, the second hole can be drilled using a drilling machine. By analogy, when drilling multiple holes along its length, the position can be quickly adjusted while ensuring drilling accuracy, thus ensuring processing quality and efficiency.

[0025] Furthermore, the detachable connection of the placement box 2 facilitates the replacement and processing of hardware parts of different specifications, thus improving its applicability.

[0026] Preferably, the fixing mechanism 3 includes a screw 301 that extends through and is threadedly connected to the interior of the placement box 2. A pressure plate 302 is rotatably mounted on the end of the screw 301 located inside the placement box 2, and the outer surface of the pressure plate 302 is in contact with the inner wall of the placement box 2. A torsion bar 303 is mounted on the end of the screw 301 away from the pressure plate 302.

[0027] After placing the hardware parts to be processed in the placement box 2, turn the torsion bar 303 to drive the screw 301 to rotate. Since the screw 301 is rotatably connected to the pressure plate 302, and the pressure plate 302 is limited by the inner wall of the placement box 2, the screw 301 can drive the pressure plate 302 to press firmly on the surface of the hardware parts, so as to achieve the purpose of fixing.

[0028] Preferably, the positioning mechanism 4 includes a positioning rod 401 and a pressure rod 403 that pass through the push block 201, with the positioning rod 401 and pressure rod 403 distributed parallel to each other, and the positioning rod 401 being adapted to the positioning hole 101. A first rack 402 is mounted on the outer surface of the positioning rod 401, and a second rack 404 is mounted on the outer surface of the pressure rod 403. A transmission gear 405 is rotatably mounted inside the push block 201, and both the first rack 402 and the second rack 404 are meshed with the transmission gear 405. A spring 406 is connected inside the push block 201, and the end of the spring 406 is connected to the bottom of the pressure rod 403.

[0029] When the pressure bar 403 is pressed down, the positioning bar 401 can be driven to rise and be pulled out from the inside of the positioning hole 101 through the transmission action of the transmission gear 405, thereby releasing the fixation of the placement box 2. At this time, the placement box 2 can be slid horizontally on the carrier plate 1.

[0030] Furthermore, while pressing down on the pressure rod 403, it compresses the spring 406. When the pressure rod 403 is released, the compressed spring 406 pushes the pressure rod 403 upward, which in turn drives the positioning rod 401 to descend again and insert into the positioning hole 101 to fix the placement box 2.

[0031] Because the pressing release mechanism is used, in actual operation, the push block 201 and the downward pressing rod 403 can be pinched simultaneously. When the positioning rod 401 is pulled out from the positioning hole 101, the push block 201 can be directly pushed to drive the placement box 2 to slide. During the sliding process, the pressing rod 403 can be released, so that the bottom of the positioning rod 401 abuts against the surface of the carrier plate 1 under the action of the spring 406. The positioning rod 401 slides on the surface of the carrier plate 1. When it is aligned with the positioning hole 101, it can automatically insert into its interior for fixation. Therefore, the adjustment of the position of the hardware is smoother and more efficient.

[0032] Preferably, the inner walls on both sides of the push block 201 are provided with sliding grooves 5, and the outer surfaces of the positioning rod 401 and the pressure rod 403 are both equipped with sliders 501, which are disposed in the sliding grooves 5.

[0033] The limiting effect of the slide groove 5 and the slider 501 can limit the angle of the positioning rod 401 and the pressure rod 403, ensuring the stability of the meshing between the first rack 402 and the second rack 404 and the transmission gear 405.

[0034] Preferably, a positioning pin 6 is installed inside the push block 201, and a spring 406 is sleeved on the outside of the positioning pin 6.

[0035] The positioning pin 6 guides the spring 406, preventing it from deforming during frequent compression.

[0036] Preferably, a ball bearing 7 is installed at the bottom of the positioning rod 401, and the opening of the positioning hole 101 is chamfered.

[0037] The ball bearing 7 can reduce the friction between the bottom of the positioning rod 401 and the carrier plate 1, making the positioning rod 401 slide more smoothly, effortlessly and with less noise when sliding on its surface. Furthermore, by making a chamfer at the opening of the positioning hole 101, the positioning rod 401 can be more easily inserted into the positioning hole 101 for positioning.

[0038] Preferably, fixing lugs 8 are installed at both ends of the carrier plate 1 along its length.

[0039] The carrier plate 1 can be fixedly installed by fixing the ear block 8.

[0040] Preferably, the bottom wall of the placement box 2 is provided with a clearance groove 202.

[0041] The clearance groove 202 can make way for the drill bit during drilling to avoid collisions.

[0042] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0043] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
