DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0023] In one embodiment, see Figure 1 , Figure 2 and Figure 3 , a rotary positioning mechanism for boring machine tooling, includes a base 2 and a rotary seat 1, the lower end of the rotary seat 1 is located inside the base 2 and is rotatably connected to the base 2, a rotary mechanism 3 is provided inside the base 2, the rotary mechanism 3 is used to drive the rotary seat 1 to rotate, a plurality of slideways 8 distributed in a circle are provided inside the rotary seat 1, the slideways 8 run through the top and the bottom of the rotary seat 1, wherein the slideways 8 are slidably connected with sliders 7, the sliders 7 are connected with a driving mechanism 4, the driving mechanism 4 is used to drive the sliders 7 to move synchronously, the tops of the sliders 7 are rotatably connected with clamps 6, the clamps 6 are connected with a flipping mechanism 5, the flipping mechanism 5 is used to drive the clamps 6 to flip, so that the clamps 6 no longer clamp the workpiece.

[0024] In this embodiment, when the present invention processes a cylindrical workpiece, the workpiece is placed on the top of the rotating seat 1, and then the sliders 7 inside the multiple slideways 8 are driven to move synchronously by the driving mechanism 4, and the sliders 7 drive the clamping plates 6 to move toward the direction of the workpiece until the clamping plates 6 complete the fixation of the workpiece. After the workpiece is fixed, the side wall of the workpiece can be drilled by the boring machine. When the side wall of one orientation of the workpiece is processed, the rotating seat 1 is driven to rotate by the rotating mechanism 3, and the rotating seat 1 drives the workpiece to rotate through multiple circumferentially distributed clamping plates 6, so that the boring machine can process the side walls of the workpiece in other orientations, which effectively improves the scope of application, and the clamping plates 6 It is connected to the slider 7 through the flipping mechanism 5. When one of the clamping plates 6 rotates to the position corresponding to the boring machine tool, the flipping mechanism 5 drives the clamping block 9 to flip, thereby flipping the clamping plate 6 to the inside of the slide 8. The clamping plate 6 no longer clamps the workpiece. At this time, the workpiece can still be fixed only by the remaining clamping plates 6, thereby ensuring the stable performance of the workpiece during processing. The clamping plate 6 located at the position corresponding to the boring machine tool is flipped to the inside of the slide 8, so that no matter how the workpiece rotates, the boring machine tool can process the side wall of the workpiece, which can effectively avoid the phenomenon that the clamping plate 6 blocks the workpiece, thereby causing the boring machine tool to be unable to process the side wall of the workpiece, thereby improving the scope of application.

[0025] See also Figure 2 The rotating mechanism 3 includes a motor 33 fixedly connected to the bottom of the base 2, a gear 32 is installed at the output end of the motor 33, and a gear ring 31 is fixed to the bottom of the rotating base 1, and the gear ring 31 is meshed with the gear 32;

[0026] When it is necessary to process the side walls of the workpiece in different directions, start the motor 33, which drives the gear 32 to rotate. The engagement between the gear 32 and the gear ring 31 drives the rotating seat 1 to rotate, and then drives the workpiece to rotate, so that the boring machine tool can process the side walls of the workpiece in different directions, effectively improving the scope of application.

[0027] See also Figure 1 A limiting ring 34 is fixed on the top of the base 2, and the limiting ring 34 extends into the interior of the rotating base 1 and is rotatably connected to the rotating base 1;

[0028] The limiting ring 34 can play a supporting and limiting role on the rotating seat 1, thereby effectively improving the stability of the rotating seat 1 during rotation.

[0029] See also Figure 2 and Figure 3The driving mechanism 4 includes a traction rope 42 fixedly connected to the slider 7, a wire groove distributed in a circumferential manner is provided inside the rotating seat 1, one end of the wire groove extends to the inside of the slideway 8, and the other end of the wire groove passes through the bottom of the rotating seat 1, a telescopic rod 41 is installed at the bottom of the rotating seat 1, and a fixing plate 59 is fixed at the bottom of the telescopic rod 41, the traction rope 42 passes through the inside of the wire groove and is fixedly connected to the baffle 43, wherein a reset component is provided inside the slideway 8, and the reset component is used to reset the slider 7;

[0030] When the workpiece needs to be processed, the baffle 43 is driven downward by the telescopic rod 41. While the baffle 43 moves downward, the slider 7 is pulled by the traction rope 42. The slider 7 drives the clamp 6 to move toward the workpiece until the clamp 6 completes the fixation of the workpiece, which can effectively ensure the stability of the workpiece during processing. When the workpiece is processed, the telescopic rod 41 drives the baffle 43 to move upward, and the baffle 43 no longer pulls the slider 7 through the traction rope 42. The slider 7 is automatically reset under the action of the reset component.

[0031] See also Figure 3 The reset assembly includes a guide rod 44 fixedly connected to the inner wall of the slide 8, the guide rod 44 passes through the slider 7 and is slidably connected to the slider 7, and a first elastic component 45 is provided outside the guide rod 44, and the two ends of the first elastic component 45 are respectively fixedly connected to the side wall of the slider 7 and the inner wall of the slide 8;

[0032] When fixing the workpiece, the slider 7 squeezes the first elastic component 45, so that the first elastic component 45 is in a compressed state. When the workpiece is processed, the traction rope 42 no longer pulls the slider 7, and the first elastic component 45 releases the elastic potential energy, so that the slider 7 automatically resets, and the clamping plate 6 no longer clamps the workpiece. The guide rod 44 can play a limiting role on the slider 7, which effectively improves the stability of the slider 7 when moving.

[0033] See also Figure 5 The flip mechanism 5 includes a rotating rod 55 fixedly connected to the side wall of the clamping plate 6 and symmetrically distributed, and the top of the slider 7 is integrally formed with symmetrically distributed protrusions 53, wherein the clamping plate 6 is connected to the protrusion 53 through a torsion spring 54, and the rotating rod 55 is rotatably connected to the protrusion 53. The side wall of the slider 7 is provided with an extrusion component, which is used to squeeze the clamping plate 6, so that the clamping plate 6 can fix the workpiece;

[0034] When fixing the workpiece, the clamp 6 is in a vertical state under the action of the extrusion assembly. At this time, the slider 7 can drive the clamp 6 to move synchronously, thereby completing the fixation of the workpiece. When one of the sliders 7 is in the position of the boring machine tool, the extrusion assembly connected to the slider 7 no longer squeezes the clamp 6. The clamp 6 automatically flips to the inside of the slide 8 under the action of the torsion spring 54, so that the clamp 6 no longer clamps the workpiece, which can effectively avoid the interference of the clamp 6 with the boring machine tool, so that the boring machine tool can process any position of the side wall of the workpiece, effectively improving the application range of the mechanism.

[0035] See also Figure 3 , Figure 4 and Figure 5 The extrusion assembly includes a fixed plate 59 fixedly connected to the side wall of the slider 7, a push rod 58 runs through the inside of the fixed plate 59, the push rod 58 is slidably connected to the fixed plate 59, an extrusion block 56 is fixedly connected to the upper end of the push rod 58, and the extrusion block 56 is connected to the fixed plate 59 through a second elastic component 57. An extrusion ring 51 for extruding the push rod 58 is fixed to the bottom of the base 2, and the top of the extrusion ring 51 has a concave portion 52 that is concave downward;

[0036] The push rod 58 is squeezed through the top of the squeezing ring 51, so that the push rod 58 squeezes the side wall of the clamp plate 6 through the squeezing block 56, so that the clamp plate 6 is in a vertical state and can fix the workpiece. When one of the clamp plates 6 rotates to the position of the boring machine tool, the push rod 58 connected to the slider 7 just rotates to the position of the recessed portion 52 at the top of the squeezing ring 51. At this time, the squeezing ring 51 no longer squeezes the push rod 58. The push rod 58 and the squeezing block 56 automatically move downward under the action of the second elastic component 57. The second elastic component 57 can be a spring, so that the squeezing block 56 no longer squeezes the clamp plate 6. The clamp plate 6 automatically resets under the action of the torsion spring 54, thereby flipping to the inside of the slide 8, thereby avoiding the interference of the clamp plate 6 with the boring machine tool.

[0037] See also Figure 5 The clamping blocks 9 are fixed on the sides of the clamping plates 6 that are close to each other, and the side walls of the clamping blocks 9 have anti-slip threads;

[0038] The arrangement of the clamping block 9 can effectively improve the fixing effect of the clamping plate 6 on the workpiece, thereby ensuring the stable performance of the workpiece during machining.

[0039] Working principle: When processing a cylindrical workpiece, the present invention places the workpiece on the top of the rotating seat 1, and drives the baffle 43 to move downward through the telescopic rod 41. While the baffle 43 moves downward, the slider 7 is pulled by the traction rope 42, and the slider 7 drives the clamping plate 6 to move in the direction of the workpiece until the clamping plate 6 completes the fixation of the workpiece. After the workpiece is fixed, the side wall of the workpiece can be drilled by the boring machine. When the side wall of one orientation of the workpiece is processed, the motor 33 is started, and the motor 33 drives the gear 32 to rotate. The engagement between the gear 32 and the gear ring 31 drives the rotating seat 1 to rotate, and then drives the workpiece to rotate, so that the boring machine tool can process the side walls of the workpiece in different orientations, effectively improving the scope of application, and when one of the clamping plates 6 rotates to the position of the boring machine tool, the push rod 58 connected to the slider 7 just rotates to the top of the extrusion ring 51. The depressed portion 52 is in the position, at this time, the extrusion ring 51 no longer squeezes the push rod 58, the push rod 58 and the extrusion block 56 automatically move downward, so that the extrusion block 56 no longer squeezes the clamp 6, and the clamp 6 automatically resets under the action of the torsion spring 54, thereby flipping to the inside of the slide 8, thereby avoiding the clamp 6 from interfering with the movement of the boring machine tool, and at this time, the top of the extrusion ring 51 can also squeeze the remaining push rods 58, and the push rod 58 squeezes the clamp 6 through the extrusion block 56, so that the clamp 6 is in a vertical state and completes the fixation of the workpiece, and the workpiece can still be fixed through the remaining clamps 6, thereby ensuring the stability of the workpiece during machining. When the workpiece is processed, the telescopic rod 41 drives the baffle 43 to move upward, and the baffle 43 no longer pulls the slider 7 through the traction rope 42, and the slider 7 automatically resets, thereby releasing the clamping state of the clamp 6 on the workpiece.
