Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically to a drilling equipment that can prevent shaking. Background Technology

[0002] Drilling equipment is a common tool in machining, construction and decoration, equipment maintenance and other fields. It drives the drill bit to rotate at high speed and feed it into the workpiece to achieve drilling operations on various materials such as metal, wood and plastic. Handheld drilling equipment is widely used in various small and medium-sized drilling scenarios due to its portability, flexibility and low operating threshold.

[0003] However, the stability of existing handheld drilling equipment during drilling operations depends on the operator's grip strength and skill. When the operator's hand shakes, the feed force is uneven, or the workpiece surface is uneven, the drill bit is easily deviated from the preset axis, causing radial wobbling, which in turn leads to problems such as reduced drilling accuracy, hole position displacement, and rough hole wall. In severe cases, it may even cause the drill bit to break and the workpiece to be scrapped. Utility Model Content

[0004] The purpose of this invention is to provide a drilling device that can prevent shaking, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device with anti-sway capability, comprising a gun body and a drill bit, wherein an anti-sway component is provided at the end of the gun body, the anti-sway component includes a connecting plate, the connecting plate is fixedly connected to the end of the gun body, a ring is fixedly connected to the end of the connecting plate, a guide rod is slidably connected inside the ring, a limit block is fixedly connected to one end of the guide rod, a fitting ring is fixedly connected to the other end of the guide rod, a spring is provided between the ring and the fitting ring, and multiple sets of arrayed positioning holes are opened on the outer wall of the guide rod.

[0006] Preferably, a limiting component is provided on the outer wall of the guide rod. The limiting component includes a collar, which is sleeved on the outer wall of the guide rod. The collar is in contact with the end of the spring. A fixing frame is fixedly connected to the outer wall of the collar. A through hole is opened at the end of the fixing frame, and an insert rod is slidably connected in the through hole. The insert rod passes through and is slidably connected to the inner wall of the collar and is inserted into the positioning hole.

[0007] Preferably, an anti-slip ring is fixedly connected to the side wall of the fitting ring.

[0008] Preferably, the spring is sleeved on the outer wall of the guide rod.

[0009] Preferably, a U-shaped rod is fixedly connected to the end of the insertion rod.

[0010] Preferably, a protrusion is fixedly connected to the outer wall of the insertion rod, and the protrusion is elastically connected to the inner wall of the fixing frame by a spring.

[0011] Compared with the prior art, this utility model provides a drilling device that can prevent shaking, which has the following beneficial effects:

[0012] 1. This anti-sway drilling equipment limits the radial displacement of the drill body and drill bit through the sliding cooperation between the guide rod and the ring in the anti-sway component. Combined with the attachment and positioning of the fitting ring and the anti-slip ring, it reduces the swaying amplitude of the drill bit during drilling operations and improves drilling accuracy.

[0013] 2. This anti-shake drilling equipment achieves position locking of the fitting ring in non-working state and sliding unlocking in working state through the insertion and cooperation of the limit component's plug rod and the guide rod's positioning hole. At the same time, the elastic reset function of spring one ensures that the fitting ring and drill bit automatically return to their original positions after drilling, reducing non-working wear of the drill bit.

[0018] like Figures 1-3As shown, this utility model provides a technical solution: a drilling device with anti-sway capability, including a gun body 1 and a drill bit 2. An anti-sway component 3 is provided at the end of the gun body 1. The anti-sway component 3 includes a connecting plate 31, which is fixedly connected to the end of the gun body 1, achieving a stable connection between the anti-sway component 3 and the gun body 1. A ring 32 is fixedly connected to the end of the connecting plate 31. A guide rod 33 is slidably connected inside the ring 32. One end of the guide rod 33 is fixedly connected to a limiting block 34, and the other end is fixedly connected to a fitting ring 35. The ring 32 serves as the sliding track for the guide rod 33. The limiting block 34 prevents the guide rod 33 from falling out of the inner hole of the ring 32. The fitting ring 35 fits against the surface of the object to be drilled, ensuring that the gun body 1 and the drill bit 2 can only move along the axis of the guide rod 33, thereby reducing the shaking of the drill bit 2 during operation and improving drilling accuracy.

[0019] An anti-slip ring 36 is fixedly connected to the side wall of the fitting ring 35. The anti-slip ring 36 increases the friction between the fitting ring 35 and the object to be drilled, preventing the fitting ring 35 from slipping during operation. A spring 37 is provided between the ring 32 and the fitting ring 35. The spring 37 is sleeved on the outer wall of the guide rod 33 and is used to return the fitting ring 35 to its original position after movement. Multiple sets of arrayed positioning holes 38 are formed on the outer wall of the guide rod 33. The positioning holes 38 cooperate with the limiting component 4 to position the fitting ring 35.

[0020] A limiting component 4 is provided on the outer wall of the guide rod 33. The limiting component 4 includes a collar 41, which is sleeved on the outer wall of the guide rod 33. The collar 41 is in contact with the end of the spring 37. A fixing frame 42 is fixedly connected to the outer wall of the collar 41. A through hole is opened at the end of the fixing frame 42, and an insert rod 43 is slidably connected in the through hole. The insert rod 43 passes through and is slidably connected to the inner wall of the collar 41 and is inserted into the positioning hole 38. A protrusion 44 is fixedly connected to the outer wall of the insert rod 43. The protrusion 44 is elastically connected to the inner wall of the fixing frame 42 by a spring 45. A U-shaped rod 46 is fixedly connected to the end of the insert rod 43. Spring 45 provides elastic support to the protrusion 44, ensuring a stable connection between the insertion rod 43 and the positioning hole 38. This allows the guide rod 33 and the fitting ring 35 to protect the drill bit 2, preventing unnecessary wear during use. The U-shaped rod 46 is used for hand gripping, ensuring the overall stability of the drilling equipment. Simultaneously, lifting the U-shaped rod 46 separates the insertion rod 43 from the positioning hole 38, allowing the fitting ring 35 and the guide rod 33 to slide together, enabling the drill bit 2 to penetrate deep into the object for drilling operations.

[0021] In this invention, during use, the operator presses the end of the fitting ring 35 furthest from the guide rod 33 firmly against the surface of the workpiece to be drilled. The anti-slip ring 36 is in close contact with the workpiece surface, increasing the friction between the fitting ring 35 and the workpiece and preventing the fitting ring 35 from sliding or shifting during drilling. At this time, the operator holds the U-shaped rod 46 on the gun body 1 and the limiting component 4 and pulls it upward, causing the insertion rod 43 to slide upward along the through hole of the fixing frame 42. At this time, the protrusion 44 on the outer wall of the insertion rod 43 moves synchronously and compresses the second spring 45 until the end of the insertion rod 43 furthest from the U-shaped rod 46 is completely disengaged from the positioning hole 38 on the outer wall of the guide rod 33, releasing the limiting lock on the guide rod 33.

[0022] The drilling equipment is started, and drill bit 2 begins to rotate at high speed. The operator slowly applies pressure towards the workpiece, and the drill body 1 drives drill bit 2 to feed along the axis of guide rod 33. During this process, ring 32 guides the sliding of guide rod 33, limiting the radial wobble of drill body 1 and drill bit 2, ensuring that drill bit 2 always drills along the preset axis. At the same time, the feeding action of drill body 1 pushes the fitting ring 35 to compress spring 37. Spring 37 is in a compressed state, providing elastic support for subsequent reset. After drilling is completed, the operator turns off the drilling equipment and stops applying pressure. The compressed spring 37 releases its elastic restoring force, pushing the fitting ring 35 and guide rod 33 to move in the opposite direction to reset. Drill bit 2 exits the drilled hole of the workpiece along with drill body 1.

[0023] At this point, the U-shaped rod 46 is released, and the elastic restoring force of the second spring 45 pushes the protrusion 44 to reset, thereby driving the insertion rod 43 to be inserted into the corresponding positioning hole 38, completing the position locking of the guide rod 33 and the fitting ring 35, while avoiding unnecessary wear of the drill bit 2 in the non-working state.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
