Description

Technical Field

[0001] The utility model relates to the technical field of copper bushing side wall drilling, in particular to a device for copper bushing side wall drilling. Background Art

[0002] Copper bushings are used outside mechanical parts to achieve sealing, wear protection and other functions. They refer to bushings that act as gaskets. In the field of valve applications, the bushings are inside the valve cover.

[0003] During the production process of the copper bushing, it is necessary to drill holes in its side wall. When drilling holes in the side wall of the copper bushing, most of the existing drilling devices clamp the two ends of the copper bushing through two clamping plates, and are not capable of clamping the inner wall of the copper bushing. Since the copper bushing is thin and the material is soft, the clamping plates on both sides squeeze and deform the copper bushing when clamping it. For this reason, we propose a device for drilling holes in the side wall of the copper bushing. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a device for drilling holes in the side walls of copper bushings, which is used to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, one side of one of the fixing plates is fixedly connected to a supporting plate, and the self-locking motor is fixedly mounted on the supporting plate.

[0008] Preferably, the drilling assembly includes an electric push rod fixedly mounted on the top of the support frame, the electric push rod extends to the interior of the support frame, a drilling motor is fixedly mounted on the output end of the electric push rod, and a drill bit is fixedly connected to the output end of the drilling motor.

[0009] Preferably, the first fixing assembly comprises a telescopic cylinder fixedly connected to the rotating shaft, the output end of the telescopic cylinder is externally fixedly sleeved with a connecting plate, and the output end of the telescopic cylinder is fixedly connected to a first trapezoidal block.

[0010] Preferably, two symmetrically distributed telescopic sleeves are fixedly connected to one side of the connecting plate, a telescopic rod is slidably connected inside the telescopic sleeve, one side of the two telescopic rods is fixedly connected to the same clamping plate, one side of the clamping plate is fixedly connected to a round shell, and a first spring is sleeved on the outside of the telescopic sleeve and the telescopic rod.

[0011] Preferably, the second fixing assembly comprises four correspondingly distributed insertion rods movably inserted on the outside of the circular shell, and one end of the four insertion rods is fixedly connected to a disc.

[0012] Preferably, the bottoms of the four insertion rods are fixedly connected with a second trapezoidal block, the second trapezoidal block is adapted to the first trapezoidal block, the top of the second trapezoidal block is fixedly connected with a second spring, and the other end of the second spring is fixedly connected to the inner wall of the circular shell.

[0013] Compared with the prior art, the utility model has the following beneficial effects: by starting the telescopic cylinder, the connecting plate, the clamping plate and the round shell move, and the round shell enters the interior of the copper bushing. At this time, the clamping plate contacts the two ends of the copper bushing, and the clamping plate will move backward, and the first trapezoidal block will enter the interior of the round shell, squeezing the four second trapezoidal blocks, and the plug rod moves, driving the disc to contact the inner wall of the copper bushing, so that the copper bushing can be clamped and fixed. Through the above structure, it is convenient for the staff to perform drilling operations on the copper bushing, and the two ends and the inner wall of the copper bushing can be clamped and fixed at the same time, avoiding the traditional clamping and fixing of the copper bushing by the clamping plates 16 on both sides, and the force generated, causing the copper bushing to deform, which greatly facilitates the use of the staff.

[0014] When it is necessary to flip the clamped copper bushing, the self-locking motor is started, the shaft rotates, the clamping plate, the round shell and the copper bushing rotate, and after rotating to the specified position, the self-locking motor is turned off to fix the copper bushing in the current position. The above structure is set up to facilitate the staff to rotate the clamped copper bushing, avoiding the traditional disadvantage that when it is necessary to drill holes in other side walls of the copper bushing, the staff needs to disassemble the copper bushing and flip it over and clamp it before drilling holes in other side walls of the copper bushing, which greatly facilitates the use of the staff.
