[0002] The working platform of the floor boring machine in the workshop is a rotatable table, and its rotation in the production process is usually driven by an electric motor to rotate the platform main shaft, so that the platform achieves the rotation effect but has no fine adjustment function. In the process of use, the working platform often needs to be fine adjusted, or when the workpiece is adjusted during production, only a few degrees or zero point several degrees need to be rotated, and only the working platform can be manually rotated. There is a rocker under the side of the platform, which is used to control the rotation angle of the platform above the machine tool, and the rocker needs to be connected and rotated by a rocker handle. However, the handle has a small working space with the lower tooling platform, and there is interference. When the handle is rotated, the fingers are easy to be stuck between the two, and similar situations have occurred, which has a great safety hazard.

[0003] Secondly, the existing boring machine adjusting rocker is directly bidirectional adjustable for the boring machine rotation angle. The connection of such a rocker is fixed and directly controlled, so when machining a workpiece, the boring machine needs to be controlled to rotate in a certain direction. If the operator shifts the shift or mistakenly reverses the direction of the rocker during operation, the boring machine will be controlled to rotate in the opposite direction, which is opposite to the expected direction of the boring machine control, which will have an irreversible impact on the machined workpiece.

DETAILED DESCRIPTION

[0024] The technical solutions of the present application will be described clearly and completely below in combination with the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Embodiment one

[0025] A boring machine platform rocker arm support, comprising a boring machine platform 1, one side of the boring machine platform 1 is provided with a T-shaped guide groove 2, the T-shaped guide groove 2 is provided with a support body 3, as shown in Figure 1 , 2 , the T-shaped guide groove 2 serves as the positioning basis of the entire support, and the support body 3 can move position along the T-shaped guide groove 2, so that the extension control of other control rods can be realized.​

[0026] Specifically, as shown in Figure 1 , 2 , the bracket body 3 is provided with an extension shaft 4 and a rocker arm shaft 5, one end of the extension shaft 4 is connected with the control shaft end of the boring machine, the rocker arm shaft 5 is connected with the extension shaft 4 and drives it to rotate, and the extension shaft 4 and the rocker arm shaft 5 extend the control end to the outside of the boring machine platform 1. One end of the extension shaft 4 is fixedly connected with the control shaft end on the boring machine, so that the control end can be extended outward to the outside of the boring machine platform 1, thereby avoiding interference with the boring machine platform 1 when the handle 9 is rotated. Specifically, the bracket body 3 forms an A-shaped bracket, the upper end of the A-shaped bracket is provided with a shaft hole 6, and the lower end is provided with two fixed plates 7, the fixed plates 7 are L-shaped plates for clamping and positioning on the edge of the boring machine platform 1, and the fixed plates 7 are provided with fixed holes 8 corresponding to the T-shaped guide groove 2. The extension shaft 4 is coaxially connected with the rocker arm shaft 5, the extension shaft 4 is rotatably connected in the shaft hole 6, and one side of the rocker arm shaft 5 is provided with a handle 9. In this embodiment, the extension shaft 4 and the rocker arm shaft 5 are the same shaft, so that the extension shaft 4 can be rotated by the handle 9 to control the boring machine, and because the extension shaft 4 extends the control point, the handle 9 extends to the outside of the boring machine platform 1, so that when the handle 9 is rotated, the hand will not be clamped on the boring machine platform 1. Example two

[0027] When the boring machine is actually used to process workpieces, the handle 9 is usually rotated to control the boring machine to rotate by a certain angle, and as the processing proceeds, the processing gradually proceeds in one direction. For large workpieces, the boring and milling usually takes a long time, and in this process, human factors are easy to confuse the previous rotation direction, and because it is opposite to the expected adjustment direction, it is easy to cause the workpiece to be damaged during processing. In order to solve such problems, as an improvement, as shown in Figures 3-8 , a one-way drive mechanism 10 is arranged in the shaft hole 6, the output end of the one-way drive mechanism 10 drives the extension shaft 4 to rotate, the rocker arm shaft 5 and the one-way drive mechanism 10 are arranged axially in parallel, the rocker arm shaft 5 and the one-way drive mechanism 10 are connected through a gear set 11, the gear set 11 is provided with two groups of forward driving group 12 and reverse driving group 13, the rocker arm shaft 5 is provided with a clutch mechanism 14, and the clutch mechanism 14 controls the output torque of the rocker arm shaft 5 to selectively connect the forward driving group 12 or the reverse driving group 13. As Figure 3As shown, the control clutch mechanism 14 is provided with a control knob 28 on one side of the support body 3, which is used to switch the control knob 28 to connect the rocker shaft 5 with the different steering control parts of the one-way drive mechanism 10, so as to control the extension shaft 4 to rotate in one direction. It can be understood that when the control knob 28 is moved to one end, the boring machine can be controlled to rotate in one direction, so that the handle 9 will not be reversed during the machining process due to human factors, and the boring machine will not be reversed. If it is necessary to control the boring machine to reverse, the control knob 28 needs to be moved to the other end, so that the boring machine can be controlled to reverse.

[0028] Specifically, the gear set 11 includes a driving gear 15 and a driven gear 16. The driving gear 15 is rotatably arranged on the rocker shaft 5, and the driven gear 16 is rotatably arranged in the shaft hole 6 and rotatably connected to the extension shaft 4. The driving gear 15 is in meshing connection with the driven gear 16. Figure 4 、 8 As shown, the two driving gears 15 are rotatably arranged on the rocker shaft 5. The driving gear 15 can be rotatably connected to the rocker shaft 5 by a bearing. The two driving gears 15 respectively drive the driven gears 16 to rotate.

[0029] Further, the one-way drive mechanism 10 includes a bidirectional drive disc 17. The extension shaft 4 is fixedly connected to the center of the bidirectional drive disc 17. The driven gears 16 of the forward drive set 12 and the reverse drive set 13 are respectively arranged on the two sides of the bidirectional drive disc 17. The distance between the two driven gears 16 remains unchanged. The two driven gears 16 are towards the friction surface 18 on one side of the bidirectional drive disc 17. The two side end faces of the bidirectional drive disc 17 are respectively provided with ball grooves 19. Steel balls 20 are arranged in the ball grooves 19. One side of the steel ball 20 is arranged in the ball groove 19, and the other side is close to the friction surface 18. Figures 5-7 As shown, the two side faces of the driving disc and the friction surface 18 are filled with steel balls 20 in the ball grooves 19. Therefore, when any one of the driven gears 16 rotates, the steel balls 20 can be driven to rotate by the friction surface 18. The two side end faces of the bidirectional drive disc 17 are respectively a forward driving face and a reverse driving face. A plurality of ball grooves 19 are uniformly distributed on each side end face in a circumferential direction. One end of the ball groove 19 is a deep groove 21, and the other end gradually transitions to a shallow groove 22. The rotation directions of the ball grooves 19 arranged on the same side end face are the same. For example, if the clutch mechanism 14 controls the power output of the gear set 11 of the forward drive set 12, the driven gear 16 of the forward drive set 12 is driven to rotate, and the friction surface 18 drives the steel ball 20 to move in the ball groove 19. Figure 5 、 6As shown, if the driven gear 16 rotates clockwise, the steel ball 20 is moved from the deep groove 21 to the shallow groove 22, and since the spacing between the bidirectional driving disc 17 and the driven gear 16 on both sides remains unchanged, the steel ball 20 is gradually pressed, so that the bidirectional driving disc 17 rotates clockwise with the driven gear 16 of the forward driving group 12, at this time, power can be transmitted to the extension shaft 4 to rotate clockwise, because the processing time is long, during which the operator changes, or the operator forgets the previous rotation direction and reversely rotates the handle 9, then the driven gear 16 of the forward driving group 12 rotates counterclockwise, the steel ball 20 moves from the shallow groove 22 to the deep groove 21, at this time the steel ball 20 can rotate freely in the deep groove 21, so that the driven gear 16 cannot transmit power to the bidirectional driving disc 17 at this time, so the rocker shaft 5 is actually in an idle state at this time, and the operator can know that the rotation direction is wrong through the "no resistance" feeling of the hand end, and as long as the rotation direction is changed, the operation can continue, thereby improving the fault tolerance of the equipment operation and avoiding the influence of the wrong processing of the workpiece due to the misoperation.

[0030] Further, as shown in the figure, Figure 8 The rotation direction of the ball groove 19 on the forward driving surface and the reverse driving surface is opposite, and when the bidirectional driving disc 17 rotates, the steel ball 20 moves from the deep groove 21 to the shallow groove 22 and pushes the steel ball 20 outward and presses it on the friction surface 18. Since the ball grooves 19 on the two end faces of the bidirectional driving disc 17 are set to be opposite, the forward driving group 12 and the reverse driving group 13 control the rotation direction of the rocker shaft 5 respectively, and the principles of the two driving groups are the same.

[0031] In use, the rocker shaft 5 controls the driving force transmitted to different driving groups through the clutch mechanism 14, so as to realize different direction rotation control of the extension shaft 4, and misoperation can be effectively avoided, and specifically, Figures 3-5As shown, the clutch mechanism 14 comprises a spline part 23 integrally formed on the rocker shaft 5, a spline sleeve 24 slidingly sleeved on the spline part 23, and a driving gear 15 rotatably arranged at each end of the spline part 23 and provided with an engaging spline towards one side of the spline part 23. The clutch mechanism 14 further comprises a yoke 27 for moving the spline sleeve 24 in the axial direction, and a key 28 arranged on the bracket body 3 and connected with the yoke 27. It can be understood that the movement of the yoke 27 in the bracket body 3 can be controlled by the external key 28, and then the spline sleeve 24 is moved on the spline part 23, and the spline sleeve 24 rotates together with the spline part 23. When the spline part 23 needs to be connected with the forward driving set 12, the spline sleeve 24 is moved to the side of the first engaging spline 25 by the yoke 27, and is sleeved on the first engaging spline 25 and the spline part 23 at the same time, and at this time the power of the rocker shaft 5 is transmitted to the forward driving set 12. Conversely, when the spline sleeve 24 is moved to the other end, the power is transmitted to the reverse driving set 13.

[0032] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
