Description

Technical Field

[0001] The utility model relates to the technical field of dividing heads, in particular to a dividing head with an anti-misoperation structure. Background Art

[0002] The dividing head is a machine tool accessory used for processing workpieces on machine tools. The dividing head in the related technology has a worm gear structure inside, and a rotating shaft is arranged through the dividing head body. One end of the rotating shaft is connected to the worm through a gear structure, and the other end of the rotating shaft is fixedly connected to a handle; turning the handle drives the rotating shaft to rotate, and the rotating shaft drives the worm to rotate through the gear structure, and the worm further drives the turbine to rotate, thereby driving the main shaft of the dividing head to rotate. Since the turbine is self-locking relative to the worm, the external force generated by the mechanical operation engineering is difficult to directly act on the main shaft to cause the main shaft to rotate.

[0003] In actual use, when the spindle rotates to a suitable position, the spindle cannot be limited. During use or processing, if a person accidentally touches the rocker connected to the spindle, the spindle will rotate, which will affect the processing. Utility Model Content

DETAILED DESCRIPTION

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a dividing head with an anti-misoperation structure, including a dividing head 1, a main shaft 2 is arranged on the surface of the dividing head 1, a linkage assembly 3 and a limit assembly 4 are arranged on the surface of the main shaft 2, and the linkage assembly 3 includes: a rocker 30, a fixed shaft 31, a groove 32, a card slot 33, a cavity 34, a rotating rod 35, a slide groove 36, a connecting plate 37, a linkage plate 38, a mounting seat 39, and a card plate 300.

[0021] The rocking arm 30 is arranged on the surface of the main shaft 2, and a fixed shaft 31 is fixed on the side of the rocking arm 30 close to the main shaft 2. A groove 32 is provided on the surface of the main shaft 2, and a card slot 33 is provided on the inner wall of the groove 32. The fixed shaft 31 is rotatably connected to the inner wall of the groove 32. A cavity 34 is provided inside the fixed shaft 31, and a rotating rod 35 is provided inside the cavity 34. The rotating rod 35 passes through the fixed shaft 31 and the rocking arm 30, and the rotating rod 35 is rotatably connected to the fixed shaft 31 and the rocking arm 30. A sliding groove 36 is provided on the inner wall of the cavity 34, and a card plate 300 is slidably connected to the inner wall of the sliding groove 36. The end of the card plate 300 away from the rotating rod 35 passes through the fixed shaft 31, and the card plate 300 is slidably connected to the fixed shaft 31. A mounting seat 39 is fixed on the surface of the card plate 300, and the surface of the mounting seat 39 is fixed by a pin The shaft is connected to a linkage plate 38, and one end of the linkage plate 38 away from the mounting seat 39 is connected to a connecting plate 37 through a pin shaft. One end of the connecting plate 37 away from the linkage plate 38 is fixed to the surface of the rotating rod 35. By rotating the circular plate 46, the rotating rod 35 rotates synchronously, and the rotating rod 35 drives the connecting plate 37 to move. Through the linkage plate 38, the mounting seat 39 and the clamping plate 300 are pulled close to the rotating rod 35 to move, and the clamping plate 300 is disengaged from the clamping slot 33. When a person accidentally touches the rocker 30, the rocker 30 drives the fixed shaft 31 to rotate, and does not drive the spindle 2 to rotate, so as to avoid accidental touch affecting subsequent processing. When the rotating rod 35 is reversed, the clamping plate 300 enters the clamping slot 33 through the connecting plate 37, the linkage plate 38, and the mounting seat 39. At this time, the rocker 30 can continue to be rotated, which can drive the spindle 2 to rotate.

[0022] The limiting assembly 4 includes a fixing ring 40, which is fixed to the surface of the rocking arm 30. A spiral spring 41 is fixed to the inner side of the fixing ring 40. The end of the spiral spring 41 away from the fixing ring 40 is fixed to the surface of the rotating rod 35. A circular plate 46 is fixed to the surface of the rotating rod 35. A limiting plate 47 is fixed to the surface of the circular plate 46. A slide plate 44 is slidably connected to the surface of the rocking arm 30. A resistance plate 45 is fixed to the side of the slide plate 44 close to the circular plate 46. A spring 43 is fixed to the side of the slide plate 44 away from the resistance plate 45. A fixing plate 42 is fixed to the end of the spring 43 away from the slide plate 44. The fixing plate 42 is fixed to the surface of the rocking arm 30. When the card plate 300 is disengaged from the card slot 33, the limiting plate 47 can be limited by the resistance plate 45 to stabilize the rotating rod 35.

[0023] The card plate 300 is consistent in shape with the card slot 33, which facilitates the card plate 300 to enter the card slot 33. There are three groups of card plates 300 and card slots 33, and the three groups of card plates 300 and card slots 33 are all arranged in a circular array with the center of the fixed shaft 31 and the main shaft 2 as the axis center, which increases the stability of the card plate 300 and the card slot 33. The shape of the fixed shaft 31 and the groove 32 is consistent, which facilitates the stable connection between the fixed shaft 31 and the main shaft 2. A limiting plate 47 is fixed on the surface of the rotating rod 35, and the limiting plate 47 can be limited by cooperating with the contact plate 45.

[0024] When the main shaft 2 is rotated by the rocker 30 for processing, the rocker 30 will drive the fixed shaft 31 and the card plate 300 to rotate synchronously. The card plate 300 is located in the card slot 33, thereby driving the main shaft 2 to rotate for processing. When the main shaft 2 rotates to a suitable position, the slide plate 44 is pulled, and the spring 43 is compressed, so that the contact plate 45 is away from the limit plate 47. At this time, the circular plate 46 is rotated to drive the rotating rod 35 to rotate synchronously. The rotating rod 35 drives the connecting plate 37 to move, and the mounting seat 39 and the card plate 300 are pulled close to the rotating rod 35 through the linkage plate 38, so that the card plate 300 is separated from the card slot 33. At the same time, when the rotating rod 35 rotates, the scroll spring 41 is rolled up, and the slide plate 44 is released at this time. The spring 43 is released, so that the slide plate 44 drives the resistance plate 45 to enter between the limit plates 47. The limit plates 47 contact the surfaces of the resistance plates 45, limit the limit plates 47 and the circular plates 46, and thus stabilize the rotating rod 35. When a person accidentally touches the rocker arm 30, the rocker arm 30 drives the fixed shaft 31 to rotate, and does not drive the spindle 2 to rotate, so as to avoid accidental touch affecting subsequent processing. When the spindle 2 needs to continue to rotate, the slide plate 44 is pulled, and the resistance plate 45 is separated from the limit plates 47. At this time, the volute spring 41 is released, driving the rotating rod 35 to reverse, and then through the connecting plate 37, the linkage plate 38, and the mounting seat 39, the card plate 300 enters the card slot 33. At this time, the rocker arm 30 can continue to be rotated, which can drive the spindle 2 to rotate.

[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
