Abstract
Description
Technical Field
[0001] The utility model belongs to pipeline connection technology, and in particular relates to a device for detecting and positioning a rolling area of a pipeline connector. Background Art
[0002] The position adjustment of the existing rolling die is usually measured by a vernier caliper or a depth vernier caliper. Due to the structure of the die itself, the position of the rolling area cannot be accurately measured. Utility Model Content
[0003] The utility model aims to detect the rolling area of a rolling die by using a special inspection tool, thereby ensuring the accuracy of the rolling area of the die and improving the rolling quality.
[0004] The technical solution of this utility model is to provide a rolling type non-flaring rolling area detection and positioning device, using a special inspection tool to check whether the extension of the needle roller meets the requirements of the technical documents for the "L" value of the rolling area. Reduce the rolling area that does not meet the requirements of the technical documents due to human measurement errors.
[0005] At the same time, the inner hole "ΦC" is used to check the maximum rolling inner diameter of the rolling die to avoid the rolling size failing to meet the requirements due to die wear.
[0006] Beneficial effects of the utility model:
[0007] 1. Use special inspection tools to detect and adjust the extension of the needle roller to ensure the accuracy of the rolling area;
[0008] 2. The maximum rolling inner diameter of the mold is set inside the inspection fixture to accurately check the wear of the mold;
[0009] 3. It has a wide range of applications and can be used as a spinning tool for pipe connectors of various specifications. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The drawings herein are incorporated into the specification and constitute a part of the specification, showing embodiments consistent with the present utility model, and together with the specification, are used to explain the principles of the present utility model. Obviously, the drawings described below are only some embodiments of the present utility model, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. In the drawings:
[0011] Figure 1 It is a schematic diagram of a rolling area detection device of a rolling die of the utility model.
[0012] Figure 2 It is a cross-sectional view of a rolling area detection device of a rolling die of the utility model.
[0013] Mainly includes: 1 cage; 2 adjusting nut; 3 mounting seat; 4 inspection fixture; 401 notch; 5 needle roller; 6 shaft; 7 bearing; 8 retaining ring. DETAILED DESCRIPTION
[0014] The example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present invention will be more comprehensive and complete, and the concept of the example embodiments will be fully conveyed to those skilled in the art.
[0015] Example:
[0016] See also Figure 1 A rolling type non-flaring rolling area detection device comprises a retainer 1, a needle roller 5 on one end of the retainer 1, an adjusting nut 2, a mounting seat 3, a cylindrical gauge 4, and a core rod 6. The adjusting nut 2 and the mounting seat 3 are axially fixed, and the retainer 1 and the adjusting nut 2 are threadedly connected. By rotating the adjusting nut 2, the retainer 1 can be moved axially, thereby driving the needle roller 5 to move axially; one end of the gauge 4 abuts against the mounting seat 3, and the other end of the gauge 4 has a circumferential notch 401 for observing the position of the probe needle roller 5. When the outer end of the needle roller 5 and the axial outer edge of the notch 401 are aligned, it can be determined that the extension of the needle roller 5, that is, the axial distance L from the outer end of the needle roller 5 to the end face of the mounting seat 3 meets the requirements of the technical documents for the "L" value of the rolling area.
[0017] The utility model discloses a method for using a rolling type non-flaring rolling area detection device as follows: the retaining frame 1, the adjusting nut 2, the mounting seat 3, and the inspection fixture 4 are sequentially sleeved on the core rod 6, the bearing 7 is installed between the mounting seat 3 and the retaining frame 1, the mounting seat 3 and the retaining frame 1 are separated, the mounting seat 3 is fixed in the axial direction, and the axial displacement of the adjusting nut 2 is limited by the retaining ring 8. The inspection fixture 4 is pressed against the end face of the mounting seat 3, and then it is observed whether the needle roller 5 is aligned with the outer edge of the notch 401. If it is not aligned, the adjusting nut 2 is rotated to adjust the axial movement of the retaining frame 1, and the needle roller 5 is driven to move axially, and the "L" value relative to the end face of the mounting seat 3 is changed until the outer end of the needle roller 5 is aligned with the outer edge of the notch 401 to ensure the rolling position.
[0018] The inner diameter of the gauge 4 is equal to the maximum rolling inner diameter of the rolling die. When the gauge 4 is used to check the maximum rolling inner diameter of the rolling die, the mandrel 6 is rotated. Under normal circumstances, the gauge 4 will rotate with the rolling die. However, when the die is worn, there is a radial gap between the gauge 4 and the rolling die, and the gauge 4 does not rotate or is stuck when rotating. The maximum rolling inner diameter of the rolling die is checked using the inner hole "ΦC" to avoid the rolling size failing to meet the requirements due to die wear.
[0019] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Any modification or equivalent substitution made to the technical solution of the utility model by ordinary technicians in this field shall be included in the scope of the claims of the utility model as long as it does not depart from the spirit and scope of the technical solution of the utility model.
