Description

Technical Field

[0001] The utility model relates to the technical field of floor spring processing, in particular to a drilling device for processing floor springs. Background Art

[0002] A floor spring is a hydraulic door closer, except that the spring-compression device uses a worm gear instead of a gear or rack. A search revealed patent publication number CN220862795U, which discloses a drilling device for drilling floor springs. The utility model comprises a housing and a floor spring. The housing is rectangular and has an inner plate for accommodating the floor spring. The inner plate is provided with a plurality of stoppers for securing the floor spring. The inner plate has a first sliding groove, within which a slider is slidably connected. The slider is provided with a detachable drill bit for drilling holes. Multiple auxiliary blocks are arranged around the inner plate, with a high-strength compression spring on one side of the auxiliary block and a stopper on the other side of the compression spring. To drill a hole in the floor spring, one of the stoppers is pushed open, and the floor spring is placed in the middle against the pushed-out stopper. The remaining stoppers then press against the floor spring, securing the floor spring. The compression springs allow for securing floor springs of different sizes, improving the practicality of the drilling device. However, during processing, the floor spring is clamped by the spring and the clamping block. Therefore, when processing floor springs of different sizes, the position of the floor spring cannot be moved, that is, the position to be processed is accurately moved under the drill bit. The cooperation between the spring and the clamping block cannot effectively move the position of the floor spring. In addition, dust generated during drilling will leak onto the surface of the processing table through the drilled hole, making it difficult to clean the dust. Utility Model Content

When the position of the floor spring needs to be moved, the clamping block 13 at one end is reset and moved in cooperation between the threaded tube 12 and the screw 11, while the clamping block 13 at the other end moves toward the position of the floor spring, so as to continue clamping the floor spring and facilitate the movement of the position of the floor spring.

[0018] Example 2

[0019] In this embodiment, Figure 1-3 As shown, the upper end of the workbench 1 is fixedly installed with a mounting frame 2, which is arranged between the two moving seats 8. The mounting frame 2 is U-shaped, and the interior of the mounting frame 2 is slidably connected to the moving plate 4. The upper end of the moving plate 4 is fixedly installed with a rotating motor 15, and the lower end side wall of the moving plate 4 is rotatably connected to the rotating seat 16. The interior of the rotating seat 16 is fastened with a drill bit 17. The output shaft of the rotating motor 15 is fixedly connected to the upper end of the rotating seat 16 by passing through the interior of the moving plate 4. A through hole 5 is provided inside the workbench 1, and the through hole 5 and the drill bit 17 are on the same axis. 2 is symmetrically fixed with an electric telescopic rod 3, and the output shaft of the electric telescopic rod 3 is fixedly connected to the upper end of the movable plate 4 by passing through the side wall of the mounting frame 2. After the position of the floor spring is completed, the electric telescopic rod 3 is turned on to move the movable plate 4 downward, and the rotary motor 15 is turned on at the same time to drive the rotary motor 16 to rotate, which can rotate the drill bit 17. With the action of the electric telescopic rod 3, the floor spring can be drilled conveniently, and after the drilling of the floor spring is completed, the drill bit 17 enters the inside of the through hole 5 without causing wear to the surface of the workbench 1.

[0020] Example 3

[0021] In this embodiment, Figure 1-3As shown, the front end of the workbench 1 is provided with a moving frame 10 and a support frame 6, and the moving frame 10 and the support frame 6 are both U-shaped. The moving frame 10 runs through the interior of the support frame 6, and the two ends of the moving frame 10 are fixedly connected to the side walls of the moving seat 8 respectively. The front end of the moving frame 10 is slidably connected to the interior of the support frame 6, and the end of the support frame 6 is fixedly connected to the front end side wall of the mounting frame 2, and a screw rod 14 is rotatably connected between the mounting frame 2 and the side wall of the support frame 6. The front end side wall of the support frame 6 is fixedly installed with a first reciprocating motor 7, and the output shaft of the first reciprocating motor 7 is fixedly connected to one end of the screw rod 14 through the interior of the support frame 6. When the floor spring is moved, the first reciprocating motor 7 is turned on to rotate the screw rod 14, thereby driving the position of the moving seat 8 to move, so that the position of the floor spring is moved, so that the floor spring can be moved horizontally and vertically, so that the position to be processed can be accurately moved to the bottom of the drill bit 17.

[0022] Example 4

[0023] In this embodiment, Figure 1-3 As shown, the rod wall of the drill bit 17 is slidably sleeved with a dust cover 18, and the side walls at both ends of the dust cover 18 are fixedly installed with connecting plates 19. The upper ends of the connecting plates 19 are fixedly installed with limiting telescopic rods 20, and the upper ends of the limiting telescopic rods 20 are fixedly connected to the bottom of the movable plate 4. When the floor spring is processed by the drill bit 17, the dust cover moves downward with the drill bit 17, and the dust cover 18 will cover the position where the hole needs to be drilled. After the drill bit enters the interior of the floor spring, the position of the dust cover 18 can be stabilized by the action of the limiting telescopic rod 20, which can reduce the dust adhering to the surface of the workbench 1 when drilling.

[0024] It should be noted that, in this embodiment, when using the drilling device for processing the floor spring, Figure 1-3As shown, when the floor spring is clamped, the floor spring 11 is placed between the two clamping blocks 13, and the reciprocating motors 9 on both sides are turned on respectively to rotate the screw 11, which conveniently moves the threaded tube 12 and clamps the floor spring with the clamping block 13. When the position of the floor spring needs to be moved, the clamping block 13 at one end is reset and moved under the cooperation between the threaded tube 12 and the screw 11, while the clamping block 13 at the other end is moved toward the position of the floor spring, so as to continue to clamp the floor spring and facilitate the movement of the position of the floor spring. While the floor spring is moving, the first reciprocating motor 7 is turned on to rotate the screw 14, so as to facilitate the movement of the position of the moving seat 8 and the position of the floor spring, so that the floor spring can be moved horizontally and vertically. The position that needs to be processed can be accurately moved to the bottom of the drill bit 17. After the position of the floor spring is placed, the electric telescopic rod 3 is turned on to move the movable plate 4 downward. At the same time, the rotating motor 15 is turned on to drive the rotating motor 16 to rotate, so that the drill bit 17 can be rotated. With the action of the electric telescopic rod 3, the floor spring can be drilled conveniently. After the floor spring is drilled, the drill bit 17 enters the inside of the through hole 5 without causing wear on the surface of the workbench 1. At the same time, when the drill bit 17 moves downward, the dust cover moves downward with the drill bit 17, and the dust cover 18 will cover the position that needs to be drilled. After the drill bit enters the inside of the floor spring, the position of the dust cover 18 can be stabilized by the action of the limiting telescopic rod 20, which can reduce the dust adhering to the surface of the workbench 1 during drilling.
