Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically a drilling tool for special vehicle hinge seats. Background Technology

[0002] Special vehicles refer to motor vehicles that have been specially designed or modified and equipped with fixed devices. Their primary function is not to carry people or goods, but rather they are typically used for towing, obstacle clearing, lifting, firefighting, medical services, and combat training. Hinges are components that connect special vehicles and are usually installed on the axle, suspension system, or body structure to allow for flexible rotation and stable support of vehicle components (such as doors).

[0003] During the machining of the hinge seat, holes need to be drilled as needed. Generally, holes are drilled at the four corners of the hinge seat to facilitate fixed installation. However, since the material of the hinge seat used in special vehicles is relatively hard, the drill bit needs to be pressed downwards. Excessive pressure may cause the drill bit to deviate during drilling, which will affect the drilling accuracy. Therefore, further improvements can be made. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a special vehicle hinge seat drilling tool, comprising a rail base, a limiting frame plate on the top inner wall of the rail base, a mounting seat for placing the hinge seat slidably connected inside the limiting frame plate, sliding grooves extending towards the center at the four corners of the mounting seat, a positioning component for positioning the hinge seat inside the mounting seat, a guide groove inside the bottom wall of the rail base, an adjusting component for driving the mounting seat to move and adjust its position inside the guide groove, and a bracket fixedly mounted on the top of one side of the rail base. A guide cylinder for guiding the drill bit is fixedly installed on the top of the bracket. A scale line is provided on the top of the other side of the rail base. A pointer is fixedly installed in the middle of the mounting base corresponding to the scale line, and the pointer slides against the scale line. The hinge seat is fixedly positioned by the positioning component inside the mounting base. Then, the drilling position is adjusted by the adjustment component driving the mounting base to slide. At the same time, the scale position indicated by the pointer is precisely adjusted. Finally, the drill bit can be pressed down to pass through the guide cylinder to drill the hinge seat. By sleeved on the outside of the drill bit, the drill bit deviation can be avoided to prevent it from affecting the drilling accuracy.

[0005] As an optimization, the positioning component includes a slider slidably connected in a groove, a clamping plate fixedly installed on the top of the slider, and the clamping plate slidably connected to the top side of the mounting base. A rotating rod is rotatably connected inside the groove. One end of the rotating rod has a threaded portion, which is screwed into the inside of the slider. A bevel gear is fixedly installed on the other end of the rotating rod. A driving component for driving the bevel gear to rotate is provided in the center of the mounting base.

[0006] As an optimization, the drive component includes a servo motor fixedly mounted at the center of the bottom of the mounting base, and a main bevel gear is fixedly mounted on the top of the output shaft of the servo motor, and the main bevel gear and the driven bevel gear are meshed together.

[0007] As an optimization, an electromagnetic base is provided in the center of the top of the mounting base.

[0008] As an optimization, the clamping plate is in the shape of a right-angled "L" and is arranged in four groups around the center of the mounting base.

[0009] As an optimization, the adjustment assembly includes a support plate fixedly installed in the middle of the bottom side of the mounting base, and the support plate is slidably connected inside the guide groove. A screw is rotatably connected inside the guide groove, and the screw is screwed into the bottom of the support plate. Both ends of the screw are fixedly installed with crank handles.

[0010] The beneficial effects of this utility model are:

[0011] By rotating the crank handle, the screw rotates inside the bottom of the support plate, which causes the mounting base to slide, thus adjusting the drilling position. At the same time, the pointer indicates the scale position, allowing for precise adjustment. Afterward, the drill bit is pressed down through the guide tube to drill the hinge seat. The guide tube, which is fitted over the outside of the drill bit, prevents the drill bit from shifting and affecting the drilling accuracy.

[0012] By starting the servo motor to drive the main bevel gear to rotate, the threaded part will rotate inside the slider through the meshing bevel gear. This will cause the slider to slide relative to each other along the slide groove, which will cause the clamping plates on top to move closer together. This will clamp the four corners of the hinge seat to position the hinge seat, making the hinge seat position in the center of the mounting base. At the same time, the electromagnetic base will further attract and position the hinge seat, improving the positioning and fastening effect. Attached Figure Description

[0019] Please see Figure 1-2 A special vehicle hinge drilling tool includes a rail base 1. The inner top wall of the rail base 1 has a limiting frame plate 2. A mounting base 3 for placing the hinge is slidably connected inside the limiting frame plate 2. The mounting base 3 has grooves extending towards the center at its four corners. A positioning component for positioning the hinge is provided inside the mounting base 3. A guide groove 4 is provided inside the bottom wall of the rail base 1. An adjustment component for driving the mounting base 3 to move and adjust its position is provided inside the guide groove 4. A bracket 5 is fixedly installed on the top of one side of the rail base 1. A tool for adjusting the drill bit is fixedly installed on the top of the bracket 5. The guide cylinder 6 is guided, and the top of the other side of the rail seat 1 is provided with a scale line 7. The middle of the mounting seat 3 is fixedly installed with a pointer 8 corresponding to the scale line 7, and the pointer 8 slides against the scale line 7. The hinge seat is fixedly positioned by the positioning component inside the mounting seat 3. Then, the mounting seat 3 is slidably adjusted by the adjustment component, and the drilling position is precisely adjusted by the scale position indicated by the pointer 8. Finally, the drill bit can be pressed down to pass through the guide cylinder 6 to drill the hinge seat. By the guide cylinder 6 being sleeved on the outside of the drill bit, the drill bit deviation can be avoided from affecting the drilling accuracy.

[0020] Please see Figure 1-2The adjustment assembly includes a support plate 17 fixedly installed in the middle of the bottom side of the mounting base 3, and the support plate 17 is slidably connected to the inside of the guide groove 4. A screw 18 is rotatably connected inside the guide groove 4, and the screw 18 is screwed into the bottom of the support plate 17. A rocker handle 19 is fixedly installed at both ends of the screw 18. By rotating the rocker handle 19, the screw 18 is driven to rotate inside the support plate 17, which can drive the mounting base 3 to slide.

[0021] Please see Figure 3-4 The positioning component includes a slider 9 slidably connected in a groove. A clamping plate 10 is fixedly installed on the top of the slider 9 and slidably connected to the top side of the mounting base 3. The clamping plate 10 is in the shape of a right-angled "L" and is arranged in four groups around the center of the mounting base 3. A rotating rod 11 is rotatably connected inside the groove. One end of the rotating rod 11 has a threaded part 12 and the threaded part 12 is screwed into the inside of the slider 9. A bevel gear 13 is fixedly installed on the other end of the rotating rod 11. A driving component for driving the bevel gear 13 to rotate is provided in the center of the mounting base 3. By activating the driving component, the bevel gear 13 will rotate, which will in turn drive the threaded part 12 to rotate inside the slider 9. Therefore, the slider 9 can be driven to slide relative to each other along the groove, which will cause the clamping plate 10 on its top to move closer together, thereby clamping the four corners of the hinge seat to position the hinge seat and positioning the hinge seat at the center of the mounting base 3.

[0022] Please see Figure 3-4 The driving component includes a servo motor 14 fixedly installed at the bottom center of the mounting base 3. A main bevel gear 15 is fixedly installed at the top of the output shaft of the servo motor 14, and the main bevel gear 15 and the driven bevel gear 13 are meshed and connected. By starting the servo motor 14, the main bevel gear 15 can be driven to rotate, which in turn will drive the driven bevel gear 13 meshed with it to rotate. A BDS Maschinen type electromagnetic base 16 is provided in the top center of the mounting base 3.

[0023] In use, the hinge is first placed on top of the mounting base 3. Then, the servo motor 14 is started to drive the main bevel gear 15 to rotate. This will drive the threaded part 12 to rotate inside the slider 9 through the bevel gear 13 that meshes with it. This will cause the slider 9 to slide relative to each other along the slide groove. This will cause the clamping plate 10 on its top to move closer together and clamp the four corners of the hinge to position the hinge, so that the hinge is positioned at the center of the mounting base 3. At the same time, the electromagnetic base 16 is started to further attract and position the hinge.

[0024] Then, by turning the crank handle 19, the screw 18 rotates inside the bottom of the support plate 17, which causes the mounting base 3 to slide, thus adjusting the drilling position. At the same time, the pointer 8 indicates the scale position of the scale line 7, allowing for precise adjustment. Finally, the drill bit can be pressed down to pass through the guide tube 6 to drill the hinge seat. The guide tube 6, which is fitted over the outside of the drill bit, prevents the drill bit from shifting and affecting the drilling accuracy.

[0025] In summary, this special vehicle hinge seat drilling tool, by rotating the crank handle 19, drives the screw 18 to rotate inside the bottom of the support plate 17, which in turn causes the mounting base 3 to slide, thus adjusting the drilling position. At the same time, precise adjustment can be made by indicating the scale position of the scale line 7 at the pointer 8. After that, the drill bit is pressed down to pass through the guide cylinder 6 to drill the hinge seat. The guide cylinder 6, which is fitted on the outside of the drill bit, can prevent the drill bit from deviating and affecting the drilling accuracy.

[0026] By starting the servo motor 14, the main bevel gear 15 is driven to rotate, which in turn drives the threaded part 12 to rotate inside the slider 9 through the meshing bevel gear 13. This causes the slider 9 to slide relative to each other along the slide groove, which in turn causes the clamping plate 10 on its top to move closer together. This clamps the four corners of the hinge seat to position the hinge seat, making the hinge seat positioned at the center of the mounting base 3. At the same time, the electromagnetic base 16 further attracts and positions the hinge seat, improving the positioning and fastening effect.
