Description

Technical Field

[0001] The utility model relates to the technical field related to oil pipe processing, in particular to a device for processing oil pipes on a numerically controlled lathe. Background Art

[0003] Although the existing fixing device can fix the oil pipe on the CNC lathe, thereby facilitating the thread processing operation of the oil pipe, the existing fixing device requires a long time of adjustment and center positioning to complete the fixing when fixing the oil pipes with different inner diameters. The operation steps are relatively cumbersome and not simple. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a device for machining oil pipes on a numerically controlled lathe.

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

[0006] A device for processing oil pipes on a CNC lathe comprises a base plate, on which a double-headed screw is rotatably connected via a bearing, two groups of vertical rods are threadedly connected on the double-headed screw, the two groups of vertical rods are rotatably connected to a column via a bearing, the outer walls of the two groups of columns are slidably connected to cones, the two groups of cones are threadedly connected to bolts, and the two groups of bolts are respectively threadedly connected to the two groups of columns.

[0007] Preferably, an arc-shaped plate is fixedly connected to the bottom plate, the arc-shaped plate is slidably connected to the two groups of vertical rods, and the arc-shaped plate is placed above the double-headed screw.

[0008] Preferably, a handle is fixedly connected to the double-headed screw.

[0009] Preferably, two groups of slide rails are fixedly connected to the bottom plate, and the two groups of slide rails are slidably connected to the two groups of vertical rods.

[0010] Preferably, a motor is installed on a group of the vertical rods, and the output end of the motor is connected to the corresponding column.

[0011] Preferably, the two groups of cylinders are placed concentrically.

[0012] Preferably, a plurality of groups of holes are processed on the bottom plate.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the coordination between the double-headed screw, vertical rod, cone, column, bolt and motor, the double-headed screw is used to drive the vertical rod to fit the two groups of cones together. The oil pipe placed between the two groups of cones will quickly fit with the cones and perform the center positioning operation due to the characteristics of the cones. The oil pipes with different inner diameters can be clamped and fixed to a certain extent, and the center positioning and fixing can be completed in a short time. The operation steps are relatively simple and easy to use;

[0015] 2. Through the coordination between the arc plate, stud screw and vertical rod, the arc plate is placed above the stud screw, and the two sets of vertical rods are slidably connected to the arc plate. When the two sets of vertical rods drive the vertebral body to clamp and fix the oil pipes of different sizes, the arc plate will shield the flying debris when the oil pipe is threaded, thereby reducing the probability of damage to the stud screw and ensuring the stability of the device in fixing the oil pipe to a certain extent.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1, reference Figures 1 to 5A device for processing oil pipes on a CNC lathe comprises a base plate 1, on which a double-headed screw 2 is rotatably connected via a bearing, the double-headed screw 2 can rotate on the base plate 1, two groups of vertical rods 3 are threadedly connected on the double-headed screw 2, the double-headed screw 2 can drive the two groups of vertical rods 3 to move outwardly on both sides or inwardly, the two groups of vertical rods 3 are rotatably connected with a column 4 via a bearing, the outer walls of the two groups of columns 4 are slidably connected with a cone 5, when the column 4 rotates, the corresponding cone 5 can be driven to rotate synchronously, the two groups of cones 5 are threadedly connected with bolts 6, the two groups of bolts 6 are respectively threadedly connected to the two groups of columns 4, and by adjusting the spacing between the two groups of cones 5, the two groups of cones 5 can clamp, fix and center the oil pipes of different sizes within a certain degree.

[0024] In this embodiment, an arc plate 7 is fixedly connected to the bottom plate 1, and the arc plate 7 is slidably connected to the two groups of vertical rods 3. The two groups of vertical rods 3 can slide at the arc plate 7. The arc plate 7 is placed above the double-headed screw 2. The arc plate 7 is used to perform a certain degree of debris interception operation on the double-headed screw 2, thereby reducing the probability of damage to the double-headed screw 2 by splashing debris from the oil pipe, and ensuring the fixing stability of the device to the oil pipe. A handle 9 is fixedly connected to the double-headed screw 2, and the handle 9 can drive the double-headed screw 2 to rotate. Two groups of slide rails 8 are fixedly connected to the bottom plate 1, and the two groups of slide rails 8 are slidably connected to the two groups of vertical rods 3. The vertical rods 3 can slide at the two groups of slide rails 8, which can increase the lateral movement of the vertical rod 3. Dynamic stability, a motor 11 is installed on a group of vertical rods 3, and the model of the motor 11 is selected according to actual work requirements. The motor 11 can cooperate with two groups of cones 5 to rotate the oil pipe clamped and fixed by the two groups of cones 5. The output end of the motor 11 is connected to the corresponding column 4, and the two groups of columns 4 are placed concentrically, so that the cones 5 placed on the two groups of columns 4 can be placed concentrically, and then when the oil pipe placed between the two is clamped, the oil pipe can be quickly clamped and fixed and the center positioning operation can be guaranteed. Multiple groups of hole bodies 10 are processed on the base plate 1, and the hole bodies 10 are used to place external connecting parts, so that the base plate 1 can be installed in an external CNC lathe.

[0025] The working principle of this embodiment is as follows: when in use, the oil pipe is placed between the two groups of cones 5. After placement, the handle 9 is turned to rotate the double-headed screw 2, and the double-headed screw 2 can drive the two groups of vertical rods 3 to move closer to each other, and then the cones 5 at the two groups of vertical rods 3 will move into one end and the other end of the inner wall of the oil pipe. By utilizing the characteristics of the cone 5, the oil pipes with different inner diameters can be quickly clamped and fixed and the center is positioned to a certain extent. After the fixation is completed, the motor 11 is connected to an external power supply, and the motor 11 can cooperate with the two groups of cones 5 to drive the oil pipe to rotate. At this time, the tool of the external CNC lathe can perform thread processing operations on the rotating oil pipe. During the processing, the debris splashed from the oil pipe will be blocked by the arc plate 7, reducing the probability of debris losing the double-headed screw 2, and ensuring the stability of the device to fix the oil pipe to a certain extent.
