Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for metal parts processing, and in particular to a drilling positioning mechanism for hinge processing. Background Technology

[0002] Hinges are a common type of metal component, primarily used to provide a rotating effect. Chinese patent application number 202322141589.4 discloses a drilling and positioning mechanism for hinge processing, comprising a processing platform and a drilling machine mounted on top of the processing platform. A square frame is fixedly connected to the top of the processing platform, and a positioning component is provided on the inner wall of the square frame. The positioning component includes a long rod and two sets of short rods, with the two sets of short rods slidably connected to both sides of the long rod. A bidirectional screw is provided inside the long rod for synchronously driving the two sets of short rods to move. An adjusting screw is rotatably connected to the side wall of the long rod for pushing the long rod to move back and forth.

[0003] In the process of using the above technology, although the cooperation of various components can achieve the effect of positioning and limiting the hinge to a certain extent, the above technology only provides clamping to the hinge through the setting of fixing parts and torsion springs, which makes the hinge not firm enough during processing. This can easily cause the hinge to fly out or shift during drilling, resulting in incorrect hole positions. Therefore, in order to solve the above technical problems, we propose a drilling positioning mechanism for hinge processing. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drilling positioning mechanism for hinge processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drilling and positioning mechanism for hinge processing includes a base plate. A bracket is provided on one side of the base plate, and a laser light is installed on the upper end of the bracket. A magnetic base is installed in the middle of the upper surface of the base plate, and a mounting frame is attached to the upper surface of the magnetic base. A first slot for accommodating the hinge is provided on the upper end of one side of the mounting frame, and a threaded rod is provided on the upper end of the other side of the mounting frame. A clamping plate is installed at the end of the threaded rod near the slot. A second slot is provided on the side of the clamping plate corresponding to the first slot. An adjusting plate is provided on the upper side of both the first and second slots. A stud is installed in the middle of the upper surface of the adjusting plate, and the upper end of the stud extends above the mounting frame and the clamping plate, respectively.

[0007] Preferably, the upper surface of the base plate is provided with an upwardly protruding barrier frame, and a cleaning port is provided on one side of the barrier frame, and a sealing plate is installed in the cleaning port.

[0008] Preferably, the lower end of the bracket is provided with several bolt holes and a fixing plate is connected to it by bolts, and the lower end of the fixing plate is fixed to the upper surface of the base plate.

[0009] Preferably, both the end of the threaded rod and the upper end of the stud are provided with polygonal prisms, and a detachable handwheel is fitted onto the threaded rod and the stud through the polygonal prisms.

[0010] Preferably, the clamping plate has guide rods at both ends on the side away from the second slot, and the other end of the guide rod passes through the frame of the mounting bracket.

[0011] Preferably, the inner walls of the first and second card slots are provided with a first anti-slip pad, and the lower surface of the adjustment plate is provided with a second anti-slip pad.

[0012] Preferably, the upper end of the bracket is provided with a fixing frame by screws, and the laser lamp is connected to the bracket through the fixing frame.

[0013] The drilling positioning mechanism for hinge processing proposed in this utility model has the following advantages:

[0014] 1. In this utility model, the mounting bracket, threaded rod, and clamping plate provide a secure clamping mechanism for the hinge, effectively preventing it from flying out due to excessive force during processing. This avoids errors in hole positioning caused by hinge displacement. Furthermore, the laser lamp allows personnel to quickly and easily move the mounting bracket by observing the laser beam's trajectory on the hinge when determining its position. This causes the hinge mounted on the mounting bracket to move synchronously until the predetermined hole position of the hinge aligns with the axis of the external drill bit. This facilitates precise drilling by external drilling equipment. In short, the laser lamp enables personnel to quickly and easily determine the drilling position of the hinge during drilling.

[0015] 2. The barrier frame in this utility model facilitates the formation of a frame on the upper surface of the base plate, preventing debris from falling during drilling operations on the hinge. This allows for easy collection of debris. The fixing plate allows for easy adjustment of the laser light's height; by changing the bolt positions, the height of the bracket can be adjusted, thus regulating the laser light's height. The anti-slip pad not only improves the clamping stability of the hinge by the slot and adjustment plate but also prevents scratches on the hinge surface, avoiding damage to the hinge's appearance after drilling and affecting its resale value. The fixing bracket facilitates the disassembly and installation of the laser light, making it easy for subsequent maintenance and replacement. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0022] Reference Figure 1-4 A drilling and positioning mechanism for hinge processing includes a base plate 1, a bracket 2 on one side of the base plate 1, a laser lamp 3 mounted on the upper end of the bracket 2, a magnetic base 4 mounted in the middle of the upper surface of the base plate 1, a mounting frame 5 adsorbed on the upper surface of the magnetic base 4, a first slot for accommodating the hinge on the upper end of one side of the mounting frame 5, a threaded rod 6 on the upper end of the other side of the mounting frame 5, a clamping plate 7 mounted on the end of the threaded rod 6 near the slot, a second slot corresponding to the first slot on the side of the clamping plate 7, an adjusting plate 8 on the upper side of both the first and second slots, a stud 9 mounted in the middle of the upper surface of the adjusting plate 8, the upper end of the stud 9 extending above the mounting frame 5 and the clamping plate 7 respectively. Example

[0023] Reference Figure 1-4 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0024] A raised barrier frame 10 is provided at the edge of the upper surface of the base plate 1. A cleaning port is provided on one side of the barrier frame 10, and a sealing plate 11 is installed inside the cleaning port. The barrier frame 10 is designed to form a frame on the upper surface of the base plate 1, so that when external drilling equipment drills the hinge, the falling debris is blocked by the barrier frame 10, that is, the debris cannot fall to other areas, thus facilitating the subsequent collection of debris. The lower end of the bracket 2 is provided with several bolt holes, and a fixing plate 12 is connected to it by bolts. The lower end of the fixing plate 12 is fixed to the upper surface of the base plate 1. This allows personnel to easily adjust the height of the laser light 3. By changing the position of the bolts, personnel can adjust the height of the bracket 2, thereby achieving the effect of adjusting the height of the laser light 3. The ends of the threaded rod 6 and the upper ends of the stud 9 are both provided with polygonal prisms 13. The threaded rod 6 and the stud 9 are fitted with detachable handwheels 14 through the polygonal prisms 13. The handwheels 14 facilitate the rotation of the threaded rod 6 and the stud 9. The polygonal prisms 13 also allow the handwheels 14 to be detached from the threaded rod 6 and the stud 9, thus preventing the handwheels 14 from interfering with external drilling equipment.

[0025] Guide rods are provided at both ends of the clamping plate 7 away from the second slot. The other end of the guide rod passes through the frame of the mounting bracket 5. The guide rods provide a limiting effect for the clamping plate 7, ensuring that the clamping plate 7 remains horizontal during movement. This prevents the clamping plate 7 from rotating and causing subsequent instability in clamping the hinge. The inner walls of the first and second slots are provided with first anti-slip pads, and the lower surface of the adjusting plate 8 is provided with second anti-slip pads. The anti-slip pads not only improve the clamping stability of the slots and adjusting plate 8 on the hinge, but also prevent the adjusting plate 8 or slots from scratching the hinge surface. This prevents the hinge from being damaged after drilling, thus affecting its sale. The upper end of the bracket 2 is provided with a fixing bracket 15 by screws. The laser light 3 is connected to the bracket 2 through the fixing bracket 15. The fixing bracket 15 facilitates the disassembly and installation of the laser light 3, making it convenient for personnel to inspect and replace the laser light 3 later.

[0026] Operating principle and advantages: In use, the laser beam emitted by the laser lamp 3 intersects with the axis of the drill bit of the external drilling equipment. The intersection point is located in the horizontal plane of the slot. The base plate 1 is set on the workbench of the external drilling equipment, that is, the base plate 1 is located below the drill bit of the external drilling equipment. When drilling is required on the hinge, the operator first places one or more hinges on one side in the first slot. Then, the adjusting plate 8 is moved by the stud 9 at the first slot, so that the adjusting plate 8 moves downward until the adjusting plate 8 finally clamps this side of the hinge. Then, by rotating the threaded rod 6, the clamping plate 7 moves towards the hinge until the second slot on the clamping plate 7 is engaged on the other side of the hinge. Then, the adjusting plate 7 at the second slot is moved until the adjusting plate 7 clamps this side of the hinge. At this time, both sides of the hinge are completely clamped by the two slots and the adjusting plate 7, thus forming a stable installation, which facilitates drilling by the external drilling equipment.

[0027] During the above process, after the hinge is fixed, the operator can move the mounting bracket 5 until the point on the hinge where the laser beam 3 falls is the same as the pre-planned drilling point. If the two points are different, the operator continues to move the mounting bracket 5 until one of the drilling points on the hinge is the same as the point where the laser beam 3 falls. Since the intersection of the laser beam 3 and the axis of the external drill bit is located in the horizontal plane of the slot, the point where the laser beam 3 falls becomes the axis of the external drill bit. This allows the external drill bit to accurately drill at the point where the laser beam 3 falls on the hinge. Thus, the operator can quickly determine whether the hinge is in an accurate position by observing the point where the laser beam 3 falls on the hinge. Once the hinge position is determined, the magnetic base 4 can be activated to fix the mounting bracket 5 in place, thus preventing the mounting bracket 5 from moving and causing drilling errors during subsequent hinge drilling.

[0028] It should be further explained that the setting of the blocking frame 10 facilitates the formation of a frame on the upper surface of the base plate 1, thereby preventing the debris from falling when external drilling equipment drills the hinge. This prevents the debris from falling to other areas, making it easier for personnel to collect it later. The setting of the fixing plate 12 facilitates the adjustment of the height of the laser light 3. By changing the position of the bolts, the height of the bracket 2 can be adjusted, thus achieving the effect of adjusting the height of the laser light 3. The setting of the handwheel 14 facilitates the operation of the threaded rod 6 and the screw... The column 9 rotates, and the polygonal prism 13 allows the handwheel 14 to be disassembled from the threaded rod 6 and the stud 9, thus preventing the handwheel 14 from interfering with external drilling equipment. The anti-slip pad not only improves the clamping stability of the hinge by the slot and the adjusting plate 8, but also prevents the adjusting plate 8 or the slot from scratching the hinge surface, thus preventing the hinge from being damaged after drilling and affecting its sale. The fixing bracket 15 facilitates the disassembly and installation of the laser lamp 3, making it easier for personnel to inspect and replace the laser lamp 3 later.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
