Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, and particularly relates to a metal workpiece position calibration mechanism for mechanical manufacturing. Background Technique

[0002] In the field of mechanical manufacturing, when producing the chain links of anchor chains, metal bars are usually placed on a processing platform for cutting. The cutting length of the metal bars is adjusted according to the size of the chain links to be produced. Then, the cut metal bars are bent by machinery to form a chain link. After retrieval, the patent with the authorization number CN218874560U discloses a metal workpiece position calibration mechanism for mechanical manufacturing. Although this mechanism solves the problem that when the metal bar is placed on the processing platform for cutting, there is no measure to limit or fix the metal bar, resulting in the metal bar being prone to deviation during the cutting process, thus affecting the cutting accuracy, the limiting sleeve used to fix the metal workpiece in this device is fixedly installed and cannot adjust its position according to the length of the workpiece. When the workpiece is short and its length is less than the distance between the limiting sleeves, the two ends cannot be fixed by the limiting sleeves. And when the workpiece is long, the two ends are far from the limiting sleeves, and the ends are prone to swing during processing, thus unable to play a good role in position calibration. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a metal workpiece position calibration mechanism for mechanical manufacturing, which solves the problem that the limiting sleeve used to fix the metal workpiece in the existing device is fixedly installed and cannot adjust the fixing position according to the length of the workpiece, thus unable to play a good role in position calibration as mentioned in the background technique.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A metal workpiece position calibration mechanism for mechanical manufacturing includes a base, guide rails, a lower clamping ring, telescopic rods, and pins. A guide rail is welded to the top of the base. There are two guide rails. The tops of the two guide rails are slidably connected to the bottom of a sliding block, and both sides of the sliding block are engaged with both sides of the guide rails. One end of the sliding block is threadedly connected to the bottom end of a positioning bolt. The other end of the sliding block is welded with a lower clamping ring at the top. One end of the lower clamping ring is rotatably connected to an upper clamping ring. The other end of the lower clamping ring is rotatably connected to both ends of a connecting shaft. The connecting shaft is rotatably connected to one end of a pin. The pin is located in a groove at the other end of the upper clamping ring, and the top of the upper clamping ring is threadedly connected to a nut. Both the upper clamping ring and the lower clamping ring are arc-shaped.

[0005] Preferably, a plurality of circular through holes are formed in the surface of the guide rail, and the circular through holes are arranged at equal intervals in a straight line. The bottom of the positioning bolt penetrates into the circular through holes on the surface of the guide rail. By sliding the sliding block, the lower clamping ring is moved to both ends of the workpiece. Then, by tightening the positioning bolt, the bottom of the positioning bolt can be inserted into the hole groove on the surface of the guide rail, so that the position of the sliding block can be fixed.

[0006] Preferably, adjusting tubes are arranged inside both the lower clamping ring and the upper clamping ring. One end of the adjusting tube is connected to the connecting cover by a bolt. The connecting cover is in threaded connection with the threaded rod. One end of the threaded rod is rotatably connected to one end of the telescopic rod. Thus, when the threaded rod rotates, it is beneficial to push the telescopic rod inside the adjusting tube to move, and then one end of the telescopic rod will extend out from one end of the adjusting tube.

[0007] Preferably, strip-shaped protrusions are arranged on both sides of the telescopic rod. The outer wall of the telescopic rod is in sliding contact with the inner wall of the adjusting tube. And a roller is arranged at the other end of the telescopic rod. The roller is rotatably connected to the telescopic rod. By contacting the surface of the workpiece with the roller, it is beneficial to enable the workpiece to rotate and adjust the appropriate processing angle during processing.

[0008] Preferably, two lower clamping rings are provided. Cylinders are embedded inside the two lower clamping rings. A positioning block is sleeved on the top telescopic end of the cylinder. The positioning block is made of flexible rubber material. The rubber material is beneficial to improving the friction between the positioning block and the workpiece.

[0009] The utility model provides a position calibration mechanism for metal workpieces in mechanical manufacturing. It has the following beneficial effects:

[0010] (1) For the position calibration mechanism for metal workpieces in mechanical manufacturing, by moving the sliding block on the surface of the guide rail, the positions of the two lower clamping rings can be adjusted. By sliding the sliding block, the lower clamping ring is moved to both ends of the workpiece. Then, by tightening the positioning bolt, the bottom of the positioning bolt can be inserted into the hole groove on the surface of the guide rail, so that the position of the sliding block can be fixed. Then, by flipping the upper clamping ring, the pin is moved to the groove at the other end of the upper clamping ring, and then the nut on the top of the pin is tightened, so that the upper clamping ring and the lower clamping ring can quickly fix the workpiece, which can play a good role in calibrating the position of the workpiece, and at the same time, the fixed position can be adjusted according to the length of the workpiece.

[0011] (2) For the metal workpiece position calibration mechanism used in mechanical manufacturing, when the diameter of the workpiece is small, by rotating one end of the threaded rod, while the threaded rod rotates, it will push the telescopic rod inside the adjusting tube to move. Then, one end of the telescopic rod will extend from one end of the adjusting tube. Thus, the roller at one end of the telescopic rod can firmly press against the surface of the workpiece, which is beneficial to fixing and calibrating the workpiece with a small diameter. At the same time, by contacting the surface of the workpiece through the roller, it is beneficial to enable the workpiece to rotate and adjust to a suitable processing angle during processing. After adjusting to a suitable angle, the positioning block is pushed by the cylinder to press against the surface of the workpiece, so that the angle of the workpiece can be fixed.

[0012] Thus, it solves the problem that the limit sleeve for fixing metal workpieces in the existing device is fixedly installed and cannot adjust the fixing position according to the length of the workpiece, and thus cannot play a good role in position calibration.

One end of the sliding block 4 is threadedly connected to one end of the bottom of a positioning bolt 3. A lower clamping ring 5 is welded to the top of the other end of the sliding block 4. One end of the lower clamping ring 5 is rotatably connected to an upper clamping ring 6. Both ends of a connecting shaft 12 are rotatably connected to the inside of the other end of the lower clamping ring 5. The connecting shaft 12 is rotatably connected to one end of the pin 13. The pin 13 is located in a groove at the other end of the upper clamping ring 6, and the top of the upper clamping ring 6 is threadedly connected to a nut 14. Both the upper clamping ring 6 and the lower clamping ring 5 are arc-shaped. A plurality of circular through holes are formed on the surface of the guide rail 2, and the circular through holes are arranged in a straight line at equal intervals. The bottom of the positioning bolt 3 penetrates into the circular through hole on the surface of the guide rail 2. By moving the sliding block 4 on the surface of the guide rail 2, the positions of the two lower clamping rings 5 can be adjusted. By sliding the sliding block 4, the lower clamping rings 5 are moved to both ends of the workpiece. Then, by tightening the positioning bolt 3, the bottom of the positioning bolt 3 can be inserted into the hole groove on the surface of the guide rail 2, so that the position of the sliding block 4 can be fixed, thus playing a better role in calibrating the position of the workpiece and being able to adjust the fixed position according to the length of the workpiece.

[0022] Example 2:

[0023] Adjusting tubes 7 are arranged inside both the lower clamping ring 5 and the upper clamping ring 6. One end of the adjusting tube 7 is connected to a connecting cover 8 by a bolt. The connecting cover 8 is threadedly connected to a threaded rod 9. One end of the threaded rod 9 is rotatably connected to one end of the telescopic rod 10. Both sides of the telescopic rod 10 are provided with strip-shaped protruding structures, and the outer wall of the telescopic rod 10 is in sliding contact with the inner wall of the adjusting tube 7.

Cylinders 15 are embedded inside the two lower clamping rings 5. A positioning block 16 is sleeved on the top telescopic end of the cylinder 15. The positioning block 16 is made of flexible rubber. When the diameter of the workpiece is small, by rotating one end of the threaded rod 9, the threaded rod 9 will push the telescopic rod 10 inside the adjusting tube 7 to move while rotating. Then, one end of the telescopic rod 10 will extend out from one end of the adjusting tube 7, so that the roller 11 at one end of the telescopic rod 10 can firmly press against the surface of the workpiece, which is beneficial to fixing and calibrating the workpiece with a smaller diameter. At the same time, by contacting the surface of the workpiece through the roller 11, it is beneficial to enable the workpiece to rotate and adjust to a suitable machining angle during machining. After adjusting to a suitable angle, the cylinder 15 is pushed to make the positioning block 16 press against the surface of the workpiece, so that the angle of the workpiece can be fixed.

[0024] Working principle: The mechanism can adjust the positions of the two lower clamping rings 5 by moving the slider 4 on the surface of the guide rail 2. The lower clamping rings 5 are moved to both ends of the workpiece by sliding the slider 4. Then, by tightening the positioning bolt 3, the bottom of the positioning bolt 3 can be inserted into the hole groove on the surface of the guide rail 2, so that the position of the slider 4 can be fixed. Then, by flipping the upper clamping ring 6, the pin 13 is moved to the groove at the other end of the upper clamping ring 6, and the nut 14 at the top of the pin 13 is tightened, so that the upper clamping ring 6 and the lower clamping ring 5 can quickly fix the workpiece, which can play a good role in position calibration of the workpiece and can adjust the fixing position according to the length of the workpiece. When the diameter of the workpiece is small, by rotating one end of the threaded rod 9, the threaded rod 9 will push the telescopic rod 10 inside the adjusting tube 7 to move while rotating. Then, one end of the telescopic rod 10 will extend from one end of the adjusting tube 7, so that the roller 11 at one end of the telescopic rod 10 can firmly press against the surface of the workpiece, which is beneficial to fixing and calibrating the workpiece with a small diameter. At the same time, by contacting the surface of the workpiece through the roller 11, it is beneficial to enable the workpiece to rotate and adjust to a suitable processing angle during processing. After adjusting to a suitable angle, the positioning block 16 is pushed by the cylinder 15 to press against the surface of the workpiece, so that the angle of the workpiece can be fixed.
