Description

TECHNICAL FIELD

[0001] The utility model relates to a milling auxiliary support device technical field, especially a kind of auxiliary support structure for preventing pipe orifice out-of-round of milling. BACKGROUND

[0002] In the pipe orifice milling process, the clamping when the pressing force size control is not good and the auxiliary support loosening in the processing process, it can lead to the roundness of pipe orifice milling process, surface crack and other risks of out-of-round. Specifically, if the pressing force is too large, it can cause the workpiece to produce bending deformation, thereby affecting the roundness, i.e. causing the pipe orifice to be out-of-round. At the same time, the pressing force that is too large can also cause the support end to produce sliding friction, causing high-temperature damage. If the pressing force is too small, the workpiece is prone to vibration under the action of cutting force, which can also cause the roundness to be out-of-round. The auxiliary support loosening can cause the workpiece to vibrate during processing, thereby affecting the roundness. Loosening can also cause the workpiece position to deviate, further affecting the processing accuracy. In the prior art, there is a lack of clamping support tool that can control the pressing force and prevent the workpiece position from deviating. SUMMARY

[0003] In view of the deficiencies of the prior art, the utility model provides an auxiliary support structure for preventing pipe orifice out-of-round of milling, which solves the roundness of pipe orifice milling process, surface crack and other risks caused by excessive pressing force of auxiliary support in the milling process.

[0013] The bottom of the gap groove is provided with a cavity with a variable width.

[0014] The cavity is a circular cavity, and the vertical center line of the gap groove coincides with the center line of the circular cavity.

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0029] like Figures 1 to 3 As shown, the auxiliary support structure for preventing milled pipe openings from becoming out of round in this embodiment includes a limiting seat, a support stud 4, and a buffer 1;

[0030] The limiting seat includes a horizontal support part 2 and a vertical support part located above the horizontal support part 2. The top of the vertical support part is provided with a threaded hole, and the support stud 4 passes through the threaded hole into the limiting seat and is threadedly connected to it.

[0031] One end of the support stud 4 extending out of the threaded hole is used to connect with the buffer 1. One end of the buffer 1 is movably engaged with the support stud 4 and is fixedly connected by fasteners. The other end is used to support the workpiece to be processed.

[0032] The support stud 4 has an axially extending inner cavity 401 at one end of the threaded hole, and its axis is consistent with the axis of the threaded hole; one end of the buffer 1 is located inside the inner cavity 401 and is movably engaged with it, while the other end extends out of the inner cavity 401.

[0033] The buffer 1 and the support stud 4 are fixedly connected to the first nut 3 via a spring washer 7. The first nut 3 can be an M12 ultra-flat fine-thread nut.

[0034] The vertical support is provided with a gap groove 201, the groove direction of which is perpendicular to the axial direction of the threaded hole, dividing the vertical support into two elastically deformable parts 202.

[0035] A locking assembly is provided between the two deformation parts 202, which is used to adjust the width of the gap groove 201, thereby adjusting the one-sided gap between the support stud 4 and the thread of the threaded hole.

[0036] The bottom of the gap groove 201 is provided with a cavity 203 with increased width that is connected to it.

[0037] The cavity 203 is a circular cavity, and the vertical center line of the gap groove 201 coincides with the center line of the circular cavity.

[0038] The gap groove 201 is not located in the middle of the vertical support part, i.e. the two elastically deformable deformation parts 202 are different.

[0039] The locking assembly comprises a screw 5 for being simultaneously threaded in the two deformation parts 202 and a second nut 6 matched with the screw 5. The screw 5 can be an M8 screw, and the second nut 6 can be an M8 nut.

[0040] A washer 8 is arranged between the support stud 4 and the limiting seat, which can be used for axial limiting.

[0041] The working principle of the auxiliary support structure for preventing the milling of the pipe orifice out of roundness in the embodiment is as follows:

[0042] Referring to Figure 4 The support structure in the embodiment is used for auxiliary supporting the shell pressing pipe orifice 9 to be processed. When used, first, the support stud 4 is screwed with the limiting seat, then the buffer 1 is moved along the inner cavity 401 to adjust the position of the buffer 1, so as to adjust the buffer distance between the buffer 1 and the shell pressing pipe orifice 9, which can be controlled to be between 5-7mm, then the spring washer 7 and the two first nuts 3 are used to fix the buffer 1 at the front end of the support stud 4, so as to ensure that the clamping force is controllable. Therefore, when clamping the shell pressing pipe orifice 9, only the buffer distance needs to be controlled, and the support stud 4 is screwed with the limiting seat, which avoids the need for adjusting the clamping force by manually sensing the reaction force of the stud in the traditional clamping process, and improves the convenience and reliability.

[0043] In addition, the limiting seat in the embodiment is provided with the gap groove 201, so that the threaded hole is divided into two sections, the width of the gap groove 201 is reduced by screwing the screw 5, so as to reduce the unilateral gap between the screw thread of the threaded hole of the support stud 4 and the limiting seat, improve the friction force between them, and solve the loosening of the auxiliary support stud in the milling process.

[0044] The tail end of the support stud 4 is provided with a handle part 402. It is convenient to screw with the limiting seat.

[0045] The buffer 1 can be an elastic damping type buffer.
