DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] A support device for a drilling machine disclosed in an embodiment of the present application, referring to Figure 1 A supporting device for a drilling machine includes two vertical rods 1, both of which are vertically fixed on a horizontally placed machine table 2. A vertical guide column 3 is fixed above the machine table 2. A driving member 21 is fixed at one end of the guide column 3 at the top. The driving member 21 can be a hydraulic cylinder. The driving member 21 includes a vertical downward output shaft, a drill bit 22 is fixed on the output shaft of the driving member 21, and a drilling tool for drilling is fixed at the bottom of the drill bit 22. A clamp 23 is fixed at a position on the machine table 2 corresponding to the drill bit 22, and the clamp 23 is used to fix the position of the workpiece to be processed.

[0036] A vertical leg 24 is fixed at the bottom of the machine 2, and the leg 24 can provide reliable support for the machine 2. Four supporting legs 241 are fixed at the bottom of each leg 24, and the four supporting legs 241 are distributed around the leg 24, so that the support of the leg 24 to the machine 2 is more stable. At the same time, a rubber buffer pad is fixed at the bottom of each supporting leg 241, and the rubber buffer pad can effectively absorb the shaking and vibration generated by the drill bit 22 during operation, thereby reducing the shaking of the drill bit 22 during operation.

[0037] Reference Figure 1 , the two vertical rods 1 are spaced apart and are both located on the same side of the drill bit 22. The vertical rod 1 can be a screw with a thread. The end of the vertical rod 1 near the top is threadedly connected with a horizontal connection block 11. The two ends of the connection block 11 along the length direction are respectively threadedly connected to the two vertical rods 1, and a fastening nut is provided at the position where the connection block 11 and the vertical rod 1 are threadedly connected. The fastening nut is threadedly connected to the vertical rod 1 and is respectively distributed on the upper and lower sides of the connection block 11. The two ends of the connection block 11 are respectively fixed to the vertical rod 1 by two fastening nuts. Two support members 12 are fixed to the position of the driving member 21 corresponding to one side of the connection block 11. The two support members 12 are both placed horizontally, and the end of the support member 12 away from the driving member 21 is detachably connected to the connection block 11 by a fixing bolt. The threaded connection between the connecting block 11 and the vertical rod 1 facilitates the height of the connecting block 11 to be adjusted with the different heights of the driving member 21. At the same time, the support member 12 and the connecting block 11 are detachably connected, which facilitates the quick disassembly and assembly between the support member 12 and the connecting block 11.

[0038] The driving member 21 is fixed to the connecting block 11 through the horizontal supporting member 12, and the connecting block 11 is fixed to the two vertical rods 1, so that the driving member 21 and the two vertical rods 1 are combined into a whole. Since the driving member 21 and the drill bit 22 are a whole, the shaking generated by the drill bit 22 when working is transmitted to the vertical rod 1 by the driving member 21. Since the vertical rod 1 is fixed to the stationary machine 2, the shaking generated by the drill bit 22 when working is transmitted to the machine 2 through the vertical rod 1. The two vertical rods 1 can provide reliable support for the drill bit 22, thereby effectively alleviating the shaking of the drill bit 22 when working.

[0039] Reference Figure 1 and Figure 2 , the two vertical rods 1 are both sleeved with a protective tube 13, and the protective tube 13 is located below the connecting block 11. The protective tube 13 can surround the vertical rod 1 to form protection, reducing the deformation of the vertical rod 1 during the support process. A horizontally placed first moving seat 14 is also provided between the two vertical rods 1. The first moving seat 14 is located below the connecting block 11. The two ends of the first moving seat 14 along the length direction are slidably connected to the protective tube 13 through a sliding sleeve, so that the first moving seat 14 can move along the vertical rod 1 in the vertical direction.

[0040] The first movable seat 14 is provided with an adjusting screw 15 perpendicular to the first movable seat 14, the adjusting screw 15 is placed horizontally, and the adjusting screw 15 is threadedly connected to the first movable seat 14. A guide rod 16 is also fixed to the position of the first movable seat 14 corresponding to the adjusting screw 15, and the guide rod 16 is fixed to the end of the first movable seat 14 close to the drill bit 22, and the guide rod 16 is parallel to the adjusting screw 15. The end of the adjusting screw 15 close to the drill bit 22 is provided with a first abutting member 4, the adjusting screw 15 is inserted into the first abutting member 4, and is rotatably connected to the first abutting member 4, and the guide rod 16 is inserted into the first abutting member 4, and is slidably connected to the first abutting member 4.

[0041] A first buffer 41 is fixed to one end of the first abutting member 4 near the drill bit 22. The first buffer 41 can be an energy-absorbing rubber pad. The first buffer 41 abuts against the drill bit 22, so that the first buffer 41 contacts the drill bit 22. The first buffer 41 can effectively absorb the vibration generated by the drill bit 22 during operation. At the same time, the shaking of the drill bit 22 can be transmitted to the vertical rod 1 through the first abutting member 4 and the first moving seat 14 to reduce the shaking of the drill bit 22. When it is necessary to adjust the tightness of the first abutting member 4 and the drill bit 22, the first abutting member 4 can be driven to move along the guide rod 16 toward or away from the drill bit 22 by rotating the adjusting screw 15, so that the first buffer 41 abuts or loosens the drill bit 22. In other embodiments of the present application, the first buffer 41 can also be connected to the drill bit 22, as long as the first buffer 41, the first abutting member 4, and the drill bit 22 form a whole, so that the shaking of the drill bit 22 can be transmitted to the vertical rod 1 through the first abutting member 4.

[0042] Reference Figure 1 and Figure 2 A connecting rod 17 may also be provided between the two vertical rods 1. The connecting rod 17 is placed horizontally, and both ends of the connecting rod 17 are slidably connected to the protective tubes 13 of the two vertical rods 1 through sliding sleeves. The connecting rod 17 can further connect the two vertical rods 1 to form a whole to strengthen the supporting strength of the vertical rods 1.

[0043] The bottom of the two vertical rods 1 are fixed with a reinforced support leg 5, the outer diameter of the reinforced support leg 5 is larger than the outer diameter of the vertical rod 1, and the reinforced support leg 5 can provide stable support for the vertical rod 1, making the vertical rod 1 more stable. A plurality of inclined auxiliary support legs 51 are distributed around the outer periphery of the reinforced support leg 5, one end of the auxiliary support leg 51 is welded to the vertical rod 1, and the other end is fixed to the machine 2. The auxiliary support leg 51 can form a supporting effect on the bottom of the vertical rod 1 to form a reliable support for the vertical rod 1, so that the vertical rod 1 can maintain its own stability in the process of limiting the shaking of the drill bit 22. At the same time, a second buffer 52 is fixed to the end of the auxiliary support leg 51 away from the vertical rod 1. The second buffer 52 can also be an energy-absorbing rubber pad. The second buffer 52 is in direct contact with the machine 2, so that the second buffer 52 can effectively absorb the vibration generated by the vertical rod 1 in the process of supporting the drill bit 22, and further maintain the stability of the vertical rod 1.

[0044] Reference Figure 3 , a second movable seat 31 is slidably connected to the guide column 3, a second abutting member 32 is fixed to the second movable seat 31, and the second abutting member 32 is fixed to the drill bit 22 at one end away from the guide column 3, so that the drill bit 22 is fixed to the guide column 3 fixed on the machine 2 as a whole through the second abutting member 32, so that the shaking of the drill bit 22 is transmitted to the guide column 3 through the second abutting member 32, further limiting the shaking of the drill bit 22, and the second abutting member 32 can move in the vertical direction with the drill bit 22, so that the second abutting member 32 can limit the shaking of the drill bit 22 in real time. In other embodiments of the present application, the second abutting member 32 can be detachably connected to the drill bit 22 to facilitate the disassembly and assembly of the second abutting member 32 and the drill bit 22, making it more flexible to use. At the same time, an energy-absorbing rubber pad can be fixed at the end of the second abutting member 32 close to the drill bit 22 to further absorb the vibration of the drill bit 22 during operation.

[0045] The implementation principle of a support device for a drilling machine according to an embodiment of the present application is as follows: two vertical rods 1 form a whole through a connecting block 11, a supporting member 12 and a driving member 21, so that the shaking generated by the drill bit 22 is transmitted to the vertical rod 1 through the supporting member 12 and the connecting block 11, and the vertical rod 1 transmits the shaking to the stationary machine 2, thereby effectively reducing the shaking of the drill bit 22. At the same time, the first clamping member 4 and the second clamping member 32 are clamped together on the drill bit 22 to further limit the shaking of the drill bit 22. The first clamping member 4 can adjust the tightness of the abutment with the drill bit 22 by adjusting the screw 15, and the auxiliary support leg 51 can provide reliable support for the vertical rod 1.
