Description

Technical Field

[0001] This utility model belongs to the field of metal processing tooling technology, specifically a metal processing tooling with positioning and clamping function. Background Technology

[0002] Currently, in metal processing, it is sometimes necessary to clamp and fix the metal, especially when processing tubular metal. Clamping and fixing devices are needed to fix the tubular metal and prevent it from rolling. However, existing technologies can only fix the tubular metal. When it is necessary to rotate the circumference of the tubular metal, it is necessary to loosen and then rotate and fix it again. This not only takes a lot of time, but it is also difficult to accurately rotate the angle when changing the surface, which can easily affect the processing effect. Therefore, a metal processing fixture with positioning and clamping function is proposed. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a metal processing fixture with positioning and clamping function. It effectively solves the problem that when clamping and fixing tubular metal, it can only have a fixing function. When it is necessary to rotate and change the circumferential surface of the tubular metal, it is necessary to loosen and then rotate and clamp again. This not only takes a lot of time, but also makes it difficult to accurately rotate the angle when changing the surface, which can easily affect the processing effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal processing fixture with positioning and clamping function, comprising a base plate, a first vertical plate, a second vertical plate, a first chuck, and a second chuck. The first and second vertical plates are both vertically arranged on the upper side of the base plate, and the first vertical plate is fixedly connected to the upper right side of the base plate. An adjustment mechanism is provided on the upper left side of the base plate. The second vertical plate is slidably connected to the base plate through the adjustment mechanism. The first and second chucks are both disposed between the first and second vertical plates. Rotary shafts are rotatably connected to the opposite sides of the first and second vertical plates through a first bearing. The opposite ends of the two rotating shafts are fixedly connected to the first and second chucks, respectively. A knob is fixedly connected to the right end of the right rotating shaft. A locking mechanism is provided between the knob and the first vertical plate. Multiple scale lines distributed in a ring are provided on the right surface of the knob.

[0005] Preferably, the adjustment mechanism includes a servo motor, a threaded rod, and a moving block. A moving groove is provided on the upper left side of the base plate. The moving block is slidably disposed in the moving groove, and the upper end of the moving block is fixedly connected to the bottom of the second vertical plate. The threaded rod is rotatably disposed in the moving groove through a second bearing, and the threaded rod is threadedly sleeved with the moving block. The left end of the threaded rod extends to the outside of the base plate. The output end of the servo motor is fixedly connected to the left end of the threaded rod through a coupling.

[0006] Preferably, the sides of both the moving block and the moving slot are T-shaped.

[0007] Preferably, the locking mechanism includes an arc-shaped rack plate, an annular rack plate, and an elastic component. An annular groove is provided on the left side of the circumferential sidewall of the knob. The annular rack plate is fixedly sleeved on the circumferential sidewall with the annular groove. The arc-shaped rack plate is disposed above the annular rack plate and can mesh with the annular rack plate. A T-shaped slide groove is provided on the right side of the first vertical plate. A T-shaped slider is slidably disposed in the T-shaped slide groove. The right end of the T-shaped slider is fixedly connected to the arc-shaped rack plate. The elastic component is disposed in the T-shaped slide groove and can apply a downward elastic force to the T-shaped slider.

[0008] Preferably, the elastic component includes a spring, a pull rod, and a pull plate. The pull rod is vertically fixed in the T-shaped groove and fixedly connected to the upper end of the T-shaped slider. The upper end of the pull rod passes through the round hole on the upper side of the T-shaped groove and is fixedly connected to the pull plate. The spring is fixedly installed at the upper end of the T-shaped slider and movably sleeved with the pull rod.

[0009] Preferably, an indicator rod is fixedly provided on the upper right side of the arc-shaped rack plate, and the right end of the indicator rod is flush with the right surface of the knob.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. In use, one end of the tubular metal is inserted into the first chuck for fixation. The adjustment mechanism moves the second vertical plate and the second chuck to the right, allowing the left end of the tubular metal to be inserted into the second chuck and fixed. A locking mechanism also locks the knob in place, preventing the first and second chucks from rotating, thus preventing the tubular metal from rotating and facilitating processing. When rotation of the tubular metal is required, the pull plate and pull rod are pulled upwards. The pull rod moves the T-shaped slider and the arc-shaped rack plate upwards, separating the arc-shaped rack plate from the ring-shaped rack plate. This allows the knob to be turned, rotating the first chuck and consequently the tubular metal. The rotation angle can be precisely controlled by the circular scale lines on the knob surface. After rotation, the pull plate is released, and a spring moves the T-shaped slider and the arc-shaped rack plate downwards, locking the knob in place. This device allows for rotation and face changing without disassembling the tubular metal, and precise control of the rotation angle, facilitating processing. Attached Figure Description

An adjustment mechanism is provided on the upper left side of the base plate 1. The second vertical plate 3 is slidably connected to the base plate 1 through the adjustment mechanism. The first chuck 4 and the second chuck 5 are both arranged between the first vertical plate 2 and the second vertical plate 3. The opposite sides of the first vertical plate 2 and the second vertical plate 3 are rotatably connected to a rotating shaft through a first bearing. The opposite ends of the two rotating shafts are fixedly connected to the first chuck 4 and the second chuck 5, respectively. The right end of the right rotating shaft extends to the right and is fixedly connected to a knob 6. A locking mechanism is provided between the knob 6 and the first vertical plate 2. The right surface of the knob 6 is provided with multiple scale lines distributed in a ring. The first chuck 4 and the second chuck 5 are both three-jaw chucks.

[0019] like Figure 1 As shown, the adjustment mechanism includes a servo motor 7, a threaded rod 8, and a moving block 9. A moving groove is provided on the upper left side of the base plate 1. The moving block 9 is slidably disposed in the moving groove, and the upper end of the moving block 9 is fixedly connected to the bottom of the second vertical plate 3. The threaded rod 8 is rotatably disposed in the moving groove through a second bearing, and the threaded rod 8 is threadedly sleeved with the moving block 9. The left end of the threaded rod 8 extends to the outside of the base plate 1. The output end of the servo motor 7 is fixedly connected to the left end of the threaded rod 8 through a coupling. The servo motor 7 can drive the threaded rod 8 to rotate. The rotation of the threaded rod 8 can drive the moving block 9 to move laterally in the moving groove. The moving block 9 drives the second vertical plate 3 to move laterally. The second vertical plate 3 drives the second chuck 5 to move laterally. Together with the first chuck 4, it can clamp and fix tubular metal of different lengths.

[0020] like Figure 1 As shown, both the moving block 9 and the moving groove have T-shaped sides, which can improve the stability of the moving block 9 moving in the moving groove.

[0021] like Figures 1-3The locking mechanism includes an arc-shaped rack plate 10, an annular rack plate 11, and an elastic component. An annular groove is formed on the left side of the circumferential sidewall of the knob 6. The annular rack plate 11 is fixedly fitted onto the circumferential sidewall with the annular groove. The arc-shaped rack plate 10 is positioned above the annular rack plate 11 and can engage with it. A T-shaped groove is formed on the right side of the first vertical plate 2. A T-shaped slider 12 is slidably disposed in the T-shaped groove. The right end of the T-shaped slider 12 is fixedly connected to the arc-shaped rack plate 10. The elastic component is disposed in the T-shaped groove and can apply a downward elastic force to the T-shaped slider 12. The elastic component includes a spring 13, a pull rod 14, and a pull plate 15. The pull rod 14 is vertically fixedly disposed in the T-shaped groove and fixedly connected to the upper end of the T-shaped slider 12. The upper end of the pull rod 14 passes through a circular hole on the upper side of the T-shaped groove and is fixedly connected to the pull plate 15. The spring 13... 3. The upper end of the T-shaped slider 12 is fixedly mounted and movably sleeved with the pull rod 14. When the tubular metal needs to be rotated, the pull plate 15 and the pull rod 14 are pulled upward. The pull rod 14 drives the T-shaped slider 12 and the arc-shaped rack plate 10 to move upward, so that the arc-shaped rack plate 10 separates from the ring rack plate 11. Thus, people can turn the knob 6 to drive the first chuck 4 to rotate, and then drive the tubular metal to rotate. The rotation angle can be precisely controlled according to the scale lines distributed in the ring on the surface of the knob 6. After the rotation is completed, the pull plate 15 is released, and the T-shaped slider 12 and the arc-shaped rack plate 10 are driven downward by the spring 13 to lock the knob 6 in place. With the above device, the tubular metal can be rotated and changed without disassembling, and the rotation angle can be precisely controlled.

[0022] like Figure 2 and Figure 4 As shown, an indicator rod 16 is fixedly installed on the upper right side of the arc-shaped rack plate 10. The right end of the indicator rod 16 is flush with the right surface of the knob 6, making it easy for people to observe the rotation angle of the knob 6.

[0023] The working principle of this utility model is as follows: In use, one end of the tubular metal is inserted into the first chuck 4 for fixation. The adjusting mechanism moves the second vertical plate 3 and the second chuck 5 to the right, causing the left end of the tubular metal to be inserted into the second chuck 5 and fixed. A locking mechanism also locks the knob 6 in place, preventing the first chuck 4 and the second chuck 5 from rotating, thus preventing the tubular metal from rotating and facilitating processing. When rotation of the tubular metal is required, the pull plate 15 and the pull rod 14 are pulled upwards. The pull rod 14 moves the T-shaped slider 12 and the arc-shaped rack plate 10 upwards, causing the arc-shaped rack plate 10 to rotate. The strip plate 10 is separated from the annular rack plate 11, allowing the knob 6 to rotate, which in turn rotates the first chuck 4, and then rotates the tubular metal. The rotation angle can be precisely controlled by the scale lines distributed in the ring on the surface of the knob 6. After rotation, the pull plate 15 is released, and the T-shaped slider 12 and the arc-shaped rack plate 10 are moved downward by the spring 13, locking the knob 6 in place. With this device, the tubular metal can be rotated and changed without disassembling, and the rotation angle can be precisely controlled, making it convenient for processing.
