[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 In this embodiment, the control cabinet drilling device includes a workbench 1 and a gantry frame 2. A movable seat 4 is installed on the crossbar of the gantry frame 2. A lifting frame 6 is slidably installed on one side of the movable seat 4. A hydraulic telescopic rod 5 for driving the lifting frame 6 to rise and fall is provided on the top of the movable seat 4. A drilling mechanism 3 is installed on one side of the lifting frame 6.

[0026] The drilling mechanism 3 includes a mounting frame 31 and an annular cover 34 mounted on the bottom of the mounting frame 31. A dust removal pipe 35 is connected to one side of the annular cover 34, which can be connected to an external dust collection device. A drill bit 33 is provided at the bottom of the mounting frame 31 and placed in the middle of the annular cover 34. A fixing block 36 is installed at the bottom of the side wall of the annular cover 34. A fan-shaped block 37 is provided at the bottom of the fixing block 36. The fan-shaped block 37 is connected to the fixing block 36 through a spring guide.

[0027] Using the above scheme, the workbench 1 and the gantry frame 2 work together to switch the position of the movable seat 4. The hydraulic telescopic rod 5 can adjust the height of the lifting frame 6, thereby fixing the position of the drilling mechanism 3. When drilling, the drill bit 33 is aligned with the drilling position of the cabinet plate. During the downward movement, the fan-shaped block 37 contacts the area around the drilling position. Then the drill bit 33 gradually presses down to drill. Under the action of the spring guide, the distance between the fan-shaped block 37 and the fixed block 36 is reduced. The fan-shaped block 37 can always be pressed down in the drilling.

[0028] Please see Figure 3 and Figure 4 The spring guide includes a slide rod 38. Each set of sector blocks 37 is connected to three sets of slide rods 38 at the top. The fixing block 36 is provided with a sliding hole for sliding of the slide rod 38. A limiting block is installed at the top of the middle set of slide rods 38. A spring 39 is sleeved on the slide rod 38 between the limiting block and the top of the fixing block 36.

[0029] Specifically, when the bottom of the sector block 37 is not in contact with other components, the spring 39 is in a normal state; when the sector block 37 is close to the fixed block 36, the spring 39 is in a stretched state.

[0030] Please see Figure 4 The fixed blocks 36 are arranged in a ring array of at least three groups, and the number of fan-shaped blocks 37 corresponds to the number of fixed blocks 36. The bottom of the fan-shaped blocks 37 is connected to a rubber pad; the rubber pad prevents slippage and absorbs the impact vibration of the drill bit 33 feed, reducing the risk of resonance.

[0031] Specifically, the evenly spaced sector blocks 37 can balance the pressure around the borehole.

[0032] Please see Figure 3 The mounting bracket 31 is equipped with a drilling motor 32 for driving the drill bit 33 to rotate;

[0033] Specifically, the drilling motor 32 can drive the drill bit 33 to rotate for drilling operations.

[0034] Please see Figure 2 The movable seat 4 is connected to a slide rail on one side, and the lifting frame 6 is provided with a slide groove that cooperates with the slide rail;

[0035] Specifically, the lifting frame 6 can slide stably on one side of the movable seat 4.

[0036] Please see Figure 1 Two sets of first lead screws 11 are rotatably mounted on the workbench 1. A first servo motor for driving the first lead screws 11 to rotate is installed at one end of the workbench 1. The bottom of the gantry frame 2 is slidably engaged with the workbench 1. The bottom of the gantry frame 2 is provided with a first screw hole that is threadedly engaged with the first lead screws 11.

[0037] Specifically, the first servo motor drives the first lead screw 11 to rotate, and the adjustable movable seat 4 moves stably horizontally on the crossbar of the gantry frame 2.

[0038] Please see Figure 1 The movable seat 4 is slidably engaged with the crossbar of the gantry frame 2. A second lead screw 21 is rotatably installed inside the crossbar. A second servo motor for driving the second lead screw 21 to rotate is installed inside the gantry frame 2. The movable seat 4 is provided with a second screw hole that is threadedly engaged with the second lead screw 21.

[0039] Specifically, the second servo motor drives the second lead screw 21 to rotate, and the adjustable gantry 2 moves stably horizontally on the worktable 1.

[0040] The working principle of this utility model is as follows: The cabinet panel to be drilled is placed on the workbench 1. During use, existing fasteners can be used to further fix the panel. The first servo motor drives the first lead screw 11 to rotate, and the adjustable moving seat 4 moves stably horizontally on the crossbar of the gantry 2. The second servo motor drives the second lead screw 21 to rotate, and the adjustable gantry 2 moves stably horizontally on the workbench 1. The workbench 1 and the gantry 2 cooperate to switch the position of the moving seat 4. The hydraulic telescopic rod 5 can adjust the height of the lifting frame 6, thereby fixing the position of the drilling mechanism 3. When drilling, the drill bit 33 is aligned with the drilling point of the cabinet panel. During the downward movement, the fan-shaped block 37 contacts the area around the drilling point. Then, the drill bit 33 gradually presses down to drill, and the distance between the fan-shaped block 37 and the fixed block 36 decreases. The spring 39 is in a stretched state, and the fan-shaped block 37 can always be pressed down in the drilling. After drilling, the drill bit 33 moves away from the cabinet panel, and the fan-shaped block 37 can be reset by the force of the spring 39.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
