[0022] The longitudinal guide rail 2 is fixed to the frame 1 by bolts and is located above the workbench 11 of the frame 1, and extends along the longitudinal direction X of the floor drilling device. The vertical guide rail 3 extends in the up and down direction and is slidably connected to the front side of the longitudinal guide rail 2 along the longitudinal direction X, so that the vertical guide rail 3 can slide along the longitudinal direction X to realize the position adjustment in the longitudinal direction X.

[0023] The drilling structure 4 includes a sliding seat 41 slidably connected to the vertical guide rail 3 in the up and down direction, a mounting seat 42 fixed to the sliding seat 41, and a driving assembly 43 fixed to the mounting seat 42. Specifically, the sliding seat 41 is slidably connected to the front side of the vertical guide rail 3. A fixing block 411 is fixed to the front side wall of the sliding seat 41 by screws, and the mounting seat 42 is fixed to the front side wall of the fixing block 411 by screws to move synchronously with the sliding seat 41. The bottom of the driving assembly 43 is provided with an output shaft 431, and the bottom of the output shaft 431 is provided with a drill bit 432 for drilling. The drill bit 432 rotates driven by the output shaft 431. In this embodiment, the driving assembly 43 is a servo motor, and the servo motor is fixed to the front side wall of the mounting seat 42.

[0024] The pressing structure 5 includes two guiding seats 51 fixed to the mounting seat 42 by screws and located on opposite sides of the drill bit 432, two guiding columns 52 and a pressing plate 53. The guiding seat 51 is provided with a guiding hole (not shown) penetrating through it up and down. The upper end of a guiding column 52 is slidably connected to a guiding hole. The pressing plate 53 corresponds to the drill bit 432 and its two ends are respectively fixed to the lower ends of the two guiding columns 52. The pressing plate 53 is provided with a through hole 531 for the drill bit 432 to pass through and penetrating through it up and down. When drilling the water leakage groove 101 of the floor, the pressing plate 53 presses the floor 100 downward, thereby improving the positioning stability of the floor 100, preventing the floor 100 from being displaced during the drilling process, ensuring the drilling accuracy, and having a simple structure and being easy to install.

[0025] Specifically, a guiding seat 51 is fixed to the front side wall of a fixed seat 511 away from the mounting seat 42, and each guiding seat 51 further includes a fixed seat 511 fixed to the front side wall of the mounting seat 42 away from the sliding seat 41 by screws. The two fixed seats 511 are respectively located on opposite sides of the drill bit 432. Specifically, the two fixed seats 511 are respectively located on the left and right sides of the drill bit 432.

[0026] For the convenience of installation, a connecting plate 521 is fixed to the bottom surface of each guide post 52. The connecting plates 521 are respectively located on opposite sides of the drill bit 432. Specifically, the connecting plates 521 are respectively located on the left and right sides of the drill bit 432. The two ends of the pressing plate 53 are respectively fixed to the bottom surfaces of the two connecting plates 521. To improve the structural strength and connection stability, the pressing structure 5 is provided with a fixing plate 54. The specific structure is as follows: the pressing structure 5 further includes a fixing plate 54. The two ends of the fixing plate 54 are respectively fixed to the bottom surfaces of the two connecting plates 521 by screws. A relief hole 541 for the drill bit 432 to pass through is formed downward on the top surface of the fixing plate 54 corresponding to the drill bit 432. The relief hole 541 penetrates the bottom surface of the fixing plate 54 and its diameter is larger than the diameter of the drill bit 432. The pressing plate 53 is fixed to the bottom surface of the fixing plate 54 by bolts and is lower than the drill bit 432, so that the pressing plate 53 presses down the floor 100 before the drill bit 432 drills, ensuring the stable positioning of the floor 100, and then the drill bit 432 drills the floor 100 after the pressing plate 53 presses down the floor 100.

[0027] A spring 522 for resetting is sleeved on each guide post 52. The spring 522 is located between the guiding seat 51 and the connecting plate 521 and abuts against the guiding seat 51 and the connecting plate 521. The upper end of the guide post 52 extends upward out of the guide hole and is fixedly connected with a positioning plate 523 located above the guiding seat 51. By providing the positioning plate 523, the downward movement stroke of the guide post 52 can be controlled.

[0028] In this embodiment, a lead screw slider structure (not shown) is provided between the vertical guide rail 3 and the sliding seat 41. The lead screw slider structure is connected to the sliding seat 41 to drive the sliding seat 41 to move up and down, realizing the lifting of the drill bit 432 to complete the feeding action. An upper limit plate 31 and a lower limit plate 32 are integrally protruded forward from the upper end and the lower end of the front side wall of the vertical guide rail 3 respectively. An expandable upper bellows tube 33 is connected between the bottom surface of the upper limit plate 31 and the top surface of the sliding seat 41, and an expandable lower bellows tube 34 is connected between the top surface of the lower limit plate 32 and the bottom surface of the sliding seat 41. The upper bellows tube 33 and the lower bellows tube 34 surround the outside of the lead screw slider structure and are connected to the vertical guide rail 3. By providing the upper bellows tube 33 and the lower bellows tube 34, the lead screw slider structure can be sealed in a closed space, achieving the purpose of protecting the lead screw slider structure and extending its service life.

[0029] The floor drilling device of the present utility model is provided with a pressing plate corresponding to the drill bit and fixed to the lower ends of two guide columns at both ends. The pressing plate is provided with a through hole for the drill bit to pass through and penetrate it vertically. When drilling the water leakage groove of the floor, the pressing plate presses the floor downward, thereby improving the positioning stability of the floor, preventing the floor from being displaced during the drilling process, and ensuring the drilling accuracy.
