The circuit is cut off by the melting of the fuse body to protect the circuit equipment from damage by overload current; the automobile fuse clip fuse is usually installed in the control box of the car and fixed to the circuit board by the fuse clip; the automobile fuse clip fuse is an important protection device in the automobile circuit. Proper use and maintenance can protect the safety of automobile circuit equipment and personnel.

[0003] A fuse clip is usually composed of a clip body and a base plate (thin sheet), the clip body is used to fix the fuse, and the base plate is used to connect the clip body and the circuit board; currently, in the production process of the clip, it is necessary to make holes at both ends of the base plate (one hole is used to pass bolts to connect the clip body, and the other hole is used to pass bolts to connect the circuit board), and the holes in the base plate require the use of drilling equipment; however, due to the small size of the base plate, the existing drilling equipment is difficult to effectively fix the base plate when drilling, which can easily lead to deviations during drilling. In view of this, we propose a drilling device for fuse clip fuses. Utility Model Content

[0031] This embodiment provides a technical solution:

[0032] See also Figure 1-Figure 6 , a drilling device for a fuse clip fuse includes a drilling mechanism 1. The drilling mechanism 1 includes a base 10, a fixing seat 11 is installed at the top center of the base 10, and a groove 111 for preventing the placement of the fuse clip is opened on the top of the fixing seat 11; a gantry 12 is also installed on the top of the fixing seat 11, and electric cylinders 13 are installed on both sides of the gantry 12; a lifting cross seat 14 is also installed above the base 10, and the piston rod end of the electric cylinder 13 is fixedly connected to the cross seat 14, and the gantry 12 passes through the two ends of the cross seat 14 and is slidably connected to the cross seat 14, and a slide groove 141 is opened at the top center of the cross seat 14, and a mounting groove 142 is opened on one side of the slide groove 141, and a double-headed screw rod 16 is rotatably installed in the slide groove 141, and a first screw rod for driving the double-headed screw rod 16 to rotate is installed in the mounting groove 142. Motor 15; the threaded grooves at both ends of the double-headed screw rod 16 are threadedly connected with connecting blocks 17, and the two opposite end faces of the two connecting blocks 17 are provided with strip grooves 171; the bottom ends of the connecting blocks 17 are installed with drilling components 18 for drilling holes in fuse clips; the drilling components 18 include a shell 181 fixedly connected to the bottom end of the connecting block 17, an interlayer 1811 is provided on the shell 181, and two meshing gears 183 are rotatably installed in the interlayer 1811, and a second motor 182 is installed on the top of the interlayer 1811, and the output shaft of the second motor 182 is coaxially keyed with the gear 183 on one side, and a drill bit 184 that passes through the shell 181 and extends downward is coaxially keyed to the gear 183 on the other side. A clamping assembly 19 is installed at each of the strip grooves 171, and the clamping assembly 19 includes a guide rod 191 fixed in the strip groove 171, and a spring 192 is sleeved on the guide rod 191. A connecting plate 193 is slidably installed at the bottom end of the guide rod 191, and the bottom end of the spring 192 is pressed against the connecting plate 193; a support rod 194 is installed at the end of the connecting plate 193, and the support rod 194 is fixedly connected to the connecting plate 193 and a pressure block 195 by bolts respectively, and a pressure block 195 for pressing the fuse clip in the placement groove 111 is installed at the bottom end of the support rod 194.

[0033] Specifically, the cross-section of the pressing block 195 is circular, and the pressing block 195 is made of rubber material. The circular cross-section can evenly disperse the pressure to ensure the pressing effect of the pressing block 195 on the clamp bottom plate. At the same time, the rubber material provides good elasticity and buffering performance, further protecting the clamp bottom plate from damage.

[0034] Specifically, positioning strips 113 are installed at both sides of the placement slot 111, and the positioning strips 113 are connected to the fixing seat 11 through bolts. This design ensures the precise position of the clip base plate in the slot to prevent it from moving or offsetting during the drilling process.

[0035] Specifically, two chip removal holes 112 are provided at the bottom of the placement groove 111, and the chip removal holes 112 are circular. The design of the chip removal holes 112 helps to remove the drill cuttings in time during the drilling process, keep the working area clean, and prevent the accumulation of drill cuttings.

[0036] Specifically, a drain groove for chip removal is provided on the top of the base 10, and the drain groove is connected to the chip removal hole 112. The connection between the drain groove and the chip removal hole 112 improves the efficiency of chip removal and reduces the workload and time of cleaning equipment.

[0037] Specifically, the outer walls on both sides of the gantry 12 are both installed with fixing plates 121, and the electric cylinder 13 is fixedly connected to the fixing plates 121 by bolts. This design provides reliable support for the installation of the electric cylinder 13.

[0038] Specifically, the placement slot 111, the pressing block 195 and the drill bit 184 are all located on the same vertical plane. This design is conducive to pressing the clamp bottom plate by the pressing block 195, and is conducive to drilling holes in the clamp bottom plate by the drill bit 184.

[0039] It should be added that the threads at both ends of the double-ended screw 16 in this embodiment are wound in opposite directions. When the double-ended screw 16 rotates, the connecting blocks 17 on both sides can move horizontally smoothly. This design facilitates the adjustment of the distance between the two connecting blocks 17, and then facilitates the adjustment of the distance between the two drill bits 184, and facilitates the adjustment of the position of the hole.

[0040] It is worth noting that the first motor 15 and the second motor 182 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0041] During specific use, the user first places the clamp base plate in the placement groove 111, and then the user turns on the power of the second motor 182, the second motor 182 starts to work, and the output shaft of the second motor 182 rotates to drive the gear 183 to rotate. Because the two gears 183 are meshed, the two gears 183 rotate synchronously. At this time, the drill bits 184 on both sides rotate synchronously, and then the user turns on the power of the electric cylinder 13, the electric cylinder 13 starts to work, the piston rod of the electric cylinder 13 contracts and drives the cross seat 14 to move downward, and the cross seat 14 synchronously drives the drilling assembly 18 and the clamping assembly 19 to move downward. When the pressure block 195 is pressed against the clamp base plate, the connecting plate 193 is forced to slide upward along the guide rod 191, and the spring 192 is compressed at the same time. At this time, the clamp base plate is clamped and fixed, and the rotating drill bit 184 contacts the clamp base plate. Under the rotation of the drill bit 184, the clamp base plate can be opened.
