Description

Technical Field

[0001] This utility model relates to the field of hinge clamps, and more specifically, to an adjustable hinge drilling clamp. Background Technology

[0002] During the manufacturing process of hinges, mounting holes are usually required on both sides of the hinge for easy installation during use. In order to ensure the accuracy of the mounting hole positions, the holes are usually drilled after assembly. This is usually done on a CNC lathe using an assembly line.

[0003] In existing hinge drilling technology, the hinge may wobble or even be sprawled open when the drill bit contacts it. Hydraulic clamps are usually used for clamping, which is costly and cumbersome. Therefore, by setting up lightweight springs and positioning plates to apply a clamping force in conjunction with the drilling machine during hinge processing, the goal of saving costs and improving accuracy can be achieved. For example, Chinese utility model patent with announcement number CN216882731U discloses a special CNC lathe clamp for hinges.

[0004] However, in actual use, it is found that since the hinge is placed directly on the drill bit, when drilling the hinge, the drill bit is prone to contact with the drill bit after passing through the hinge. Smaller drill bits are easily damaged, which increases the pressure during drilling. How to invent a hinge drilling fixture to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable hinge drilling fixture, which aims to solve the problem that the drill bit is prone to contacting the drill seat after passing through the hinge.

[0006] This utility model is implemented as follows:

[0007] This utility model provides an adjustable hinge drilling fixture, including a base and several clamping plates. A first dual-axis motor is mounted on the base, and lead screws are fixedly connected to both output ends of the first dual-axis motor. A movable seat is connected to the lead screws, and extension plates are fixedly connected to both sides of the movable seat. A second dual-axis motor is mounted on the movable seat, and drive gears are fixedly connected to both output ends of the second dual-axis motor. The clamping plates are disposed on both sides of the movable seat, and a first transmission gear and a second transmission gear are rotatably connected to the extension plates. A rotating shaft connects the first transmission gear and the second transmission gear. A toothed plate is fixedly connected to one side of the clamping plate, and the toothed plate meshes with the second transmission gear. The first transmission gear meshes with the drive gear.

[0008] Preferably, the base is provided with a sliding groove and a bracket, a guide rod is connected to the bracket, the lead screw and the first dual-axis motor are both disposed inside the sliding groove, and the two ends of the movable seat are slidably connected to the sliding groove and the bracket respectively; this facilitates the improvement of the stability of the movable seat during adjustment.

[0009] Preferably, the base is longitudinally connected with several elastic components, each elastic component having a telescopic rod inside. One end of each elastic component and telescopic rod is connected to a limiting plate, which has several through slots; this helps to improve the stability of the hinge.

[0010] Preferably, the end of the extension plate away from the movable seat has a connecting groove, and one end of the toothed plate is slidably connected to the inside of the connecting groove; this facilitates the processing of hinges of different widths.

[0011] Preferably, the second transmission gear is disposed on one side of the extension plate, and a protective cover is fixedly connected to the extension plate, with the second transmission gear disposed inside the protective cover; this helps to improve the service life of the gear plate and the second transmission gear.

[0012] Preferably, the drive gear and the first transmission gear have an umbrella-shaped structure, and the cross-section of the clamp is "L"-shaped; this makes it convenient for people to fix the hinge to the base.

[0013] The beneficial effects of this utility model are as follows: This adjustable hinge drilling jig, by setting a movable seat and a clamping plate on the base, can fix the hinge at a higher position, extending the distance between the hinge and the drill seat and reducing the contact area between the hinge and the jig. This effectively prevents the drill bit from passing through the hinge and contacting the base, providing protection for the drilling operation. The L-shaped clamping plates, arranged in a rectangular array on the base, can clamp the hinge from multiple faces. When used in conjunction with the limiting plate to clamp and limit the hinge, this improves the stability of the hinge during processing, realizes the versatility of the jig's functions, and greatly reduces the probability of drill bit damage. This adjustable hinge drilling jig, by setting an adjustment mechanism on the base and the movable seat, can adjust the position of the movable seat and the clamping plate respectively. Users can control the distance between the movable seats according to the length and width of the hinge. The toothed plate moves under the cooperation of the drive gear and multiple transmission gears, thereby controlling the change of the distance of the clamping plate on the movable seat, improving the flexibility of the jig, and adapting to the processing of hinges of different sizes, thus facilitating drilling operations.

[0022] Example, refer to Figures 1-5 An adjustable hinged drilling fixture includes a base 1 and several clamping plates 5.

[0023] A first dual-axis motor 2 is mounted on the base 1. Lead screws 3 are fixedly connected to both output ends of the first dual-axis motor 2. A movable seat 4 is connected to the lead screws 3. Extension plates 14 are fixedly connected to both sides of the movable seat 4. A second dual-axis motor 10 is mounted on the movable seat 4. Drive gears 11 are fixedly connected to both output ends of the second dual-axis motor 10. Clamping plates 5 are set on both sides of the movable seat 4. A first transmission gear 13 and a second transmission gear 17 are rotatably connected to the extension plates 14. A rotating shaft 12 is connected between the first transmission gear 13 and the second transmission gear 17. A toothed plate 16 is fixedly connected to one side of the clamping plate 5. The toothed plate 16 meshes with the second transmission gear 17, and the first transmission gear 13 meshes with the drive gear 11.

[0024] Furthermore, the base 1 is provided with a slide groove 8 and a bracket 9. A guide rod is connected to the bracket 9. The lead screw 3 and the first dual-axis motor 2 are both located inside the slide groove 8. The two ends of the movable seat 4 are slidably connected to the slide groove 8 and the bracket 9, respectively.

[0025] It should be noted that by providing guide structures on both sides of the movable seat 4, the movable seat 4 can be guided to move along a specified trajectory, which helps to improve the stability of the movable seat 4 during adjustment.

[0026] Furthermore, a number of elastic components 7 are longitudinally connected to the base 1. A telescopic rod is provided inside the elastic component 7. One end of the elastic component 7 and the telescopic rod is connected to a limiting plate 6. A number of through slots are provided on the limiting plate 6.

[0027] It should be noted that by setting a limiting plate 6 on the base 1 between the hinge and the drilling machine, the hinge can be limited in conjunction with the drilling machine, which helps to improve the stability of the hinge.

[0028] Furthermore, a connecting groove 15 is provided at the end of the extension plate 14 away from the movable seat 4, and one end of the toothed plate 16 is slidably connected to the inside of the connecting groove 15.

[0029] It should be noted that by opening the connecting groove 15 to connect the toothed plate 16 and the extension plate 14 internally, the distance between the clamping plates 5 can be adjusted, which is convenient to adapt to the processing of hinges of different widths.

[0030] Furthermore, the second transmission gear 17 is disposed on one side of the extension plate 14, and a protective cover is fixedly connected to the extension plate 14, with the second transmission gear 17 disposed inside the protective cover.

[0031] It should be noted that by providing a protective cover on the extension plate 14, the connection between the second transmission gear 17 and the gear plate 16 can be protected, which helps to improve the service life of the gear plate 16 and the second transmission gear 17.

[0032] Furthermore, the drive gear 11 and the first transmission gear 13 have an umbrella-shaped structure, and the cross-section of the clamping plate 5 is "L"-shaped.

[0033] It should be noted that the transmission through the umbrella-shaped gear structure can control the L-shaped clamp 5 to hold the hinge, making it convenient for people to fix the hinge to the base 1.

[0034] The working principle of this adjustable hinge drilling fixture is as follows: During use, the first dual-axis motor 2 on the base 1 is activated, causing the moving seat 4 to move closer to or further away from each other along the bracket 9 under the cooperation of the lead screw 3 and the sliding groove 8, until the moving seat 4 clamps the hinge from both sides. Then, the second dual-axis motor 10 on the moving seat 4 is activated, causing the drive gear 11 to drive the first transmission gear 13 to rotate on both sides. After the rotating shaft 12 drives the second transmission gear 17 to rotate, the toothed plate 16 will slide into the connecting groove 15 on the extension plate 14 as the second transmission gear 17 rotates, until the clamping plates 5 clamp the hinge from both sides. At this time, the hinge clamped on the base 1 has a relatively long reserved distance from the base 1. During drilling, the drill bit passes through the through groove on the limiting plate 6, and under the continuous pressing of the drilling machine, it drives the limiting plate 6 to move closer to the hinge. At this time, the limiting plate 6 presses the hinge from the top. After drilling is completed, the elastic component 7 drives the limiting plate 6 to automatically reset.

[0035] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
