Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a rod-shaped piece straightness detection tool. Background Art

[0002] Rod-shaped parts are prone to bending during production and processing, resulting in the straightness of the rod-shaped parts not meeting the standard. When the rod-shaped parts are bent, it is necessary to find the bent part of the rod-shaped parts and adjust the posture of the rod-shaped parts so that the bent parts of the rod-shaped parts can be straightened by pressure straightening equipment. After the straightness of the rod-shaped parts is detected and straightened, the rod-shaped parts can be used in the next process.

[0003] The current straightness detection tool can only find the bending position of the rod-shaped member, but cannot intuitively display the bending degree of the rod-shaped member being detected. Utility Model Content

[0004] In view of the above situation, the utility model provides a rod-shaped member straightness detection tool, which solves the technical problem that the existing detection tool cannot intuitively display the bending degree of the detected rod-shaped member.

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

[0006] A rod-shaped member straightness detection tool, which mainly includes: a base, a support plate, a detection tube and an indicator rod. The lower end of the support plate is fixed to the base, and the support plate is provided with a connection hole. The detection tube is provided with a detection hole matching the rod-shaped member along its axis, and the detection tube is detachably connected in the connection hole. The indicator rod is located on one side of the support plate and can move longitudinally. The lower end of the indicator rod can abut against the rod-shaped member, and if the rod-shaped member is bent, the rod-shaped member can move the indicator rod upward when the rod-shaped member is rotated.

[0007] In some embodiments of the utility model, a guide plate is fixed on the support plate, and the indicator rod is plugged into the guide plate.

[0008] In some embodiments of the utility model, a fixed plate is connected to the top of the support plate, a transmission rod is connected to the fixed plate via a first rotating shaft, the lower left side of the transmission rod abuts against the top of the indicator rod, a first gear is installed on the first rotating shaft, a second gear is installed on the fixed plate via a second rotating shaft, the second gear is meshed with the first gear, and a pointer is fixed along the radial direction of the second rotating shaft.

[0009] In some embodiments of the utility model, an arc-shaped plate is installed on the fixed plate, a scale is provided on the arc-shaped plate, and the right end of the transmission rod is used to indicate the scale.

[0010] In some embodiments of the present invention, the indicating rod includes an inserting section and a telescopic section threadedly connected to the lower end of the inserting section.

[0011] In some embodiments of the present invention, a limiting block is fixed on the upper part of the plug-in section.

[0012] In some embodiments of the present utility model, a connecting ear is fixed to the right end of the detection tube, and the connecting ear is connected to the support plate through a bolt.

[0013] In some embodiments of the present invention, a mounting hole is provided on the base.

[0014] The embodiments of the present invention have at least the following advantages or beneficial effects:

[0015] When in use, insert the rod-shaped member into the detection hole from the left side of the support plate, and move the rod-shaped member to the right. During the process of moving the rod-shaped member, if the movement of the rod-shaped member is blocked, it means that the position corresponding to the left end of the rod-shaped member and the detection tube is bent. At this time, although the rod-shaped member cannot be moved to the right any further, the rod-shaped member can still be rotated relative to the detection tube. During the rotation of the rod-shaped member, when the bent part of the rod-shaped member faces upward, the displacement of the indicator rod moving upward under the action of the rod-shaped member is the largest. If the rod-shaped member continues to be rotated, the indicator rod gradually moves downward under the action of its own gravity. The greater the displacement of the indicator rod moving upward under the action of the rod-shaped member, the more serious the bending degree of the detected rod-shaped member is intuitively indicated.

[0016] In addition, when the upward displacement of the indicator rod is the largest, it means that the bending part of the rod-shaped member being detected is facing upward. At this time, the posture of the rod-shaped member is kept unchanged, the rod-shaped member is pulled out from the left side of the support plate, and transferred to the pressure straightening device, so that the rod-shaped member can be straightened by moving the actuator of the pressure straightening device downward.

[0017] Other features and advantages of the present invention will be set forth in the following description, and in part will become apparent from the description, or may be understood by implementing the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Example

[0031] Please refer to Figure 1-Figure 2 The present embodiment provides a rod-shaped member straightness detection tool, which mainly includes: a base 1, a support plate 2, a detection tube 3 and an indicator rod 4. The lower end of the support plate 2 is fixed on the base 1, and the support plate 2 is provided with a connecting hole. The detection tube 3 is provided with a detection hole 31 matching the rod-shaped member 6 along its axis, and the detection tube 3 is detachably connected in the connecting hole. The indicator rod 4 is located on one side of the support plate 2 and can move longitudinally. The lower end of the indicator rod 4 can abut against the rod-shaped member 6. If the rod-shaped member 6 is bent, when the rod-shaped member 6 is rotated, the rod-shaped member 6 can cause the indicator rod 4 to move upward.

[0032] When in use, the rod-shaped member 6 is inserted into the detection hole 31 from the left side of the support plate 2, and the rod-shaped member 6 is moved to the right. During the process of moving the rod-shaped member 6, if the movement of the rod-shaped member 6 relative to the detection cylinder 3 is blocked, it means that the rod-shaped member 6 is bent at the position close to the left end of the detection cylinder 3. At this time, although the rod-shaped member 6 cannot be moved rightward any further, the rod-shaped member 6 can still be rotated relative to the detection cylinder 3. During the rotation of the rod-shaped member 6, when the bent portion of the rod-shaped member 6 faces upward ( Figure 1 In the state shown, the left end of the rod-shaped member 6 is bent upward), and the indicator rod 4 has the largest upward displacement under the action of the rod-shaped member 6. If the rod-shaped member 6 continues to be rotated, the indicator rod 4 will gradually move downward under the action of its own gravity. For the rod-shaped member 6 whose bending degree is difficult to judge by naked eyes, the greater the upward displacement of the indicator rod 4 under the action of the rod-shaped member 6, the more intuitively it shows that the bending degree of the detected rod-shaped member 6 is more serious. In addition, when the upward displacement of the indicator rod 4 is the largest, it means that the bending part of the detected rod-shaped member 6 is facing upward. At this time, the posture of the rod-shaped member 6 can be kept unchanged, and the rod-shaped member 6 can be pulled out from the left side of the support plate 2 and transferred to the pressure straightening device, so that the rod-shaped member 6 can be straightened by moving the actuator of the pressure straightening device downward.

[0033] A guide plate 21 is fixed on the support plate 2 , and the indicator rod 4 is plugged into the guide plate 21 , so that the guide plate 21 can guide the upward and downward movement of the indicator rod 4 .

[0034] The top of the support plate 2 is connected to a fixed plate 22, and a transmission rod 24 is connected to the fixed plate 22 via a first rotating shaft 23. The lower left side of the transmission rod 24 abuts against the top of the indicator rod 4. A first gear 25 is installed on the first rotating shaft 23. A second gear 27 is installed on the fixed plate 22 via a second rotating shaft 26. The second gear 27 meshes with the first gear 25, and a pointer 28 is fixed along the radial direction of the second rotating shaft 26. Through the arrangement of the transmission rod 24, the first gear 25 and the second gear 27, the upward movement of the indicator rod 4 can be converted into a rotational movement of the pointer 28 rotating with the first rotating shaft 23, and the displacement of the indicator rod 4 can be amplified, so that the bending degree of the rod-shaped member 6 can be intuitively judged by observing the size of the angle change of the pointer 28.

[0035] In order to facilitate observation of the angle change of the pointer 28 , an arc plate 29 is mounted on the fixed plate 22 , and a scale is provided on the arc plate 29 . The right end of the transmission rod 24 is used to indicate the scale.

[0036] The indicator rod 4 includes an inserting section 41 and a telescopic section 42 threadedly connected to the lower end of the inserting section 41. The length of the indicator rod 4 can be adjusted by rotating the telescopic section 42. The benefit of adjusting the length of the indicator rod 4 is that, on the one hand, the lower end of the telescopic section 42 can be ensured to abut against the rod-shaped member 6, and on the other hand, it is convenient to adjust the initial position of the pointer 28 as needed.

[0037] A limiting block 411 is fixed on the upper portion of the plug-in section 41 , and the limiting block 411 is used to prevent the indicating rod 4 from falling off the guide plate 21 .

[0038] In order to facilitate the disassembly, assembly and replacement of the detection cylinder 3, a connecting ear 32 is fixed to the right end of the detection cylinder 3, and the connecting ear 32 is connected to the support plate 2 by bolts. There can be multiple detection cylinders 3, and the outer diameters of the multiple detection cylinders 3 can be the same. The diameter of the detection hole 31 of each detection cylinder 3 can be set according to the specifications of the rod-shaped member 6. When it is necessary to detect rod-shaped members 6 of various specifications, only the corresponding detection cylinder 3 needs to be replaced, without replacing the entire tooling.

[0039] The base 1 is provided with a mounting hole 11 so as to fix the base 1 at a suitable position by means of commonly used fasteners such as screws.

[0040] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be combined with each other at will. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
