Description

Technical Field

[0001] The utility model relates to the technical field of steel ball processing, in particular to a clamping and positioning device for steel ball drilling. Background Art

[0002] Steel ball drilling is a common processing method, usually used to make holes on steel balls. Before drilling the steel ball, the position of the steel ball needs to be fixed before the drilling operation can be performed:

[0003] However, when clamping and positioning the existing steel balls, it was found that the clamping force was mainly applied from both sides of the steel balls. After the position of the steel balls was fixed, the steel balls were drilled from above. Although this drilling method can also complete the drilling operation, the clamping force is transmitted from both sides of the steel balls to the center of the steel balls, and the force for drilling the steel balls is transmitted from the top of the steel balls to the steel balls. When the clamping force is not enough, the steel balls will be offset, and when the clamping force is too large, the steel balls will be easily damaged during the clamping process. Utility Model Content

[0004] The utility model aims to provide a clamping and positioning device for steel ball drilling, so as to solve the problem in the background technology that the direction of the clamping force is different from the direction of the drilling force, resulting in the deviation of the steel ball or damage to the steel ball.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping and positioning device for steel ball drilling, comprising a workbench and a drilling table, wherein the bottom end of the workbench is provided with a drilling table, and further comprising a positioning frame and a clamping frame, wherein the workbench is provided with a positioning frame, and the clamping frame is provided above the positioning frame;

[0006] The positioning frame comprises an external frame body, an adjustment plate, a bottom clamping end plate, an adjustment frame, a positioning rod and a threaded rod. An adjustment plate is arranged inside the external frame body. The ends of the two adjustment plates close to each other are both provided with a bottom clamping end plate, and the bottom clamping end plate is fixedly mounted on the adjustment plate. The end of the adjustment plate away from the bottom clamping end plate is fixedly mounted with an adjustment frame. The adjustment frame is penetrated by the positioning rod. A threaded rod is arranged below the positioning rod, and the threaded rod is threadedly connected to the adjustment frame.

[0007] The clamping frame comprises a clamping half frame and an electric push rod, and the top end of the clamping half frame is fixedly connected with the electric push rod.

[0008] Preferably, the clamping frame further comprises a supporting frame, the supporting frame is arranged on the outer side of the electric push rod, and the supporting frame is fixedly connected to the electric push rod.

[0009] Preferably, the drilling platform comprises a lifting push rod, a driving motor and a drill bit, the driving motor is fixedly mounted on the top end of the lifting push rod, and the drill bit is fixedly mounted on the top rotating shaft of the driving motor.

[0010] Preferably, the positioning rod is fixedly connected to the external frame, the positioning rod and the threaded rod are parallel to each other, and the positioning rod is movably connected to the adjustment frame.

[0011] Preferably, the two bottom clamping end plates form a group, and a clamping half frame is provided directly above each group of bottom clamping end plates.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model discloses a clamping and positioning device for steel ball drilling, which lifts the steel ball from the bottom through two bottom clamping end plates, and then pushes the clamping half frame through an electric push rod to apply pressure to the steel ball from top to bottom, so that the clamping half frame and the bottom clamping end plate can clamp the steel ball. This clamping method subjects the steel ball to a clamping force in a vertical direction. When the steel ball is subjected to the impact force of the drill bit from bottom to top, which is in the same vertical direction as the clamping force, the steel ball can be stably clamped without increasing the clamping force, and this clamping method can effectively prevent the steel ball from deflecting.
