Description

Technical Field

[0001] This utility model relates to the field of drilling technology for low-voltage switchgear, and in particular to a drilling device for the cabinet of a low-voltage switchgear. Background Technology

[0002] As core equipment for power distribution and control, the processing quality of low-voltage switchgear directly affects the safety and reliability of the equipment. Drilling holes in the cabinet is a critical process in low-voltage switchgear production, used to install various electrical components, wires, and connecting parts. The precision, positional accuracy, and processing efficiency of the drilling play a decisive role in the overall performance and assembly efficiency of the switchgear. Therefore, drilling equipment is required to perform drilling operations on the cabinet during the processing of low-voltage switchgear.

[0003] Existing drilling equipment for low-voltage switchgear often requires workers to hand-hold an electric drill to drill holes in the cabinet. This makes it difficult to guide and correct the drill bit. At the moment the drill bit contacts the cabinet surface, uneven hand force and drill vibration can easily cause the drill bit to deviate from the intended drilling trajectory. Once the drill bit enters the cabinet, the deviation problem becomes more and more serious as the drilling depth increases. This deviation not only causes the drilled hole position to deviate from the design requirements, affecting the installation accuracy of subsequent electrical components and the cabinet's sealing performance, reducing the assembly quality of the low-voltage switchgear, but may also damage the cabinet's structural strength and create safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a cabinet drilling device for low-voltage switchgear processing, so as to solve the defect of existing cabinet drilling devices for low-voltage switchgear processing that are inconvenient to guide and correct the drill bit.

The positioning ring has a guide hole inside and a guide rod is movably connected inside the positioning ring. One end of the guide rod is fixedly connected to a positioning support plate. A shock-absorbing pad is fixedly connected to one side of the positioning support plate, and a return spring is installed on the other side of the positioning support plate.

[0008] Preferably, the positioning ring forms a sliding structure with the guide rod through the guide holes. The guide holes are arranged in a ring around the central axis of the positioning ring, which allows the guide rod to slide along the guide holes.

[0009] Preferably, the reset spring is sleeved and installed on the outer wall of the guide rod, and the reset spring is placed between the positioning retaining ring and the positioning support plate, so that the guide rod can be reset after sliding.

[0010] Preferably, the positioning clasp is arranged parallel to the positioning support plate, and the positioning support plate is bonded to the shock-absorbing pad, which can improve the stability of the drill bit during drilling.

[0011] Preferably, the outer wall of the positioning support plate is equipped with an assembly mechanism. The assembly mechanism includes a docking groove formed inside the positioning support plate, a slot formed on the inner side wall of the docking groove, a docking block installed inside the docking groove, a movable groove formed inside the docking block, a spring protrusion movably connected inside the docking block, and a scale fixedly connected to the outer wall of the docking block.

[0012] Preferably, the positioning support plate is connected to the docking block by a docking groove, and the docking block is T-shaped, which allows the docking block to be inserted into the docking groove for snap-fit ​​installation.

[0013] Preferably, the docking block forms a sliding structure with the spring protrusion through the movable groove, and the spring protrusion is engaged with the positioning support plate through the slot, so that the end of the spring protrusion can be engaged in the slot for limiting.

[0014] The present invention provides a cabinet drilling device for processing low-voltage switchgear, the advantages of which are:

[0015] By using a drilling gun, drill bit, and correction mechanism, the drilling gun is pushed to drive the guide rod to slide along the guide hole, so that the rotating drill bit can drill into the low-voltage switchgear in a straight line. This facilitates the guidance and correction of the drill bit, prevents the drill bit from deviating during drilling, and improves the quality of drilling in the low-voltage switchgear.

[0016] Furthermore, under the action of the return spring, the positioning support plate can be reset after drilling, which facilitates the next drilling operation.

[0017] Furthermore, by installing a shock-absorbing pad on one side of the positioning support plate, the vibration generated during drilling operations can be reduced, further improving the stability of drilling operations for low-voltage switchgear.

[0018] By using the positioning support plate and assembly mechanism, and by moving the scale, the mating block can be inserted into the mating groove, which can assemble the positioning support plate and the scale, making it easier to measure the drilling position and further improving the quality of drilling processing of low-voltage switchgear.

[0019] Furthermore, the engagement of the spring protrusion and the slot improves the stability of the scale installation, and allows for the replacement of scales of different lengths according to the size differences of the low-voltage switchgear. Attached Figure Description

[0027] Please see Figures 1-5 The present invention provides a cabinet drilling device for processing low-voltage switchgear, including a drilling gun 1.

[0028] Reference Figure 1 , Figure 2 and Figure 3As shown, a drill bit 2 is installed at the output end of the drilling gun 1. A correction mechanism 3 is installed on the outer wall of the drilling gun 1. The correction mechanism 3 includes a positioning ring 31 fixedly installed on the outer wall of the drilling gun 1. A guide hole 32 is opened inside the positioning ring 31. A guide rod 33 is movably connected inside the positioning ring 31. A positioning support plate 34 is fixedly connected to one end of the guide rod 33. A shock-absorbing pad 35 is fixedly connected to one side of the positioning support plate 34. A return spring 36 is installed on the other side of the positioning support plate 34. The positioning ring 31 and the guide rod 33 form a sliding structure through the guide hole 32. The guide hole 32 is arranged in a ring around the central axis of the positioning ring 31. The return spring 36 is sleeved and installed on the outer wall of the guide rod 33. The return spring 36 is placed between the positioning ring 31 and the positioning support plate 34. The positioning ring 31 and the positioning support plate 34 are arranged parallel to each other. The positioning support plate 34 is bonded to the shock-absorbing pad 35.

[0029] By moving the drill gun 1 and placing one side of the positioning support plate 34 against the low-voltage switchgear, starting the drill gun 1 can rotate the drill bit 2. Then, pushing the drill gun 1 will drive the guide rod 33 to slide along the guide through hole 32, causing the return spring 36 to contract under the pressure of the positioning ring 31 and the positioning support plate 34, so that the rotating drill bit 2 can drill into the low-voltage switchgear in a straight line. After drilling is completed, the thrust on the drill gun 1 is slowly released. Under the action of the return spring 36, the positioning ring 31 can be reset, and the drill bit 2 installed at the output end of the drill gun 1 can be moved out of the low-voltage switchgear, completing the drilling operation.

The docking block 43 is T-shaped. The docking block 43 and the spring protrusion 45 form a sliding structure through the movable groove 44. The spring protrusion 45 is engaged with the positioning support plate 34 through the slot 42.

[0031] By moving the scale 46, the mating block 43 is inserted into the mating groove 41, and the inner wall of the mating groove 41 presses against the spring protrusion 45, causing the spring protrusion 45 to slide along the movable groove 44 and retract into the mating block 43. When the mating block 43 is fully inserted into the mating groove 41, the spring protrusion 45 can be reset under the action of the spring, and its end can be locked into the slot 42 for limiting.
