Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a vertical automatic grinder. Background Art

[0002] A grinder is a machine that grinds the surface of a workpiece with a grinding tool coated or embedded with abrasives. It is mainly used to grind high-precision planes, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in the workpiece. Due to the different speeds of the outer and inner rings of the grinding disc, the outer and inner rings of the grinding area will have different processing degrees during grinding, affecting the flatness of the workpiece grinding surface.

[0003] The prior art combines revolution and rotation to make the workpiece rotate while it revolves around the grinding disc, so as to improve the flatness of the workpiece. However, this method causes a high wear rate on the contact surface between the grinding disc and the workpiece, resulting in poor machining accuracy. The grinding disc needs to be frequently trimmed, and other intact areas of the grinding disc are also cut, resulting in waste in the use of the grinding disc. Utility Model Content

[0011] Furthermore, there are multiple linear mechanisms and rotating mechanisms, and the number is the same.

[0012] In the above technical solution, the vertical automatic grinding machine provided by the utility model has the beneficial effects of:

[0013] Through the power mechanism, the rotation of the grinding disc drives the external gear to rotate, and the rotation of the external gear drives the placement disc to move back and forth along the radial direction of the grinding disc through the linear mechanism, so that the workpiece placed in the placement hole is ground.

[0025] See also Figure 1-5 A vertical automatic grinding machine includes a frame 1, a grinding disc 2 is rotatably arranged on the frame 1, a power mechanism is also arranged on the frame 1, the power mechanism includes an outer gear ring 21 and a linear mechanism, the outer gear ring 21 is fixedly connected to the grinding disc 2, a placement disc 3 is connected to the linear mechanism, a plurality of placement holes 31 are opened on the placement disc 3, and the outer gear ring 21 drives the placement disc 3 to move along the radial direction of the grinding disc 2 through the linear mechanism. A motor is arranged in the frame 1, and the output end of the motor is fixedly connected to the grinding disc 2, so that the grinding disc 2 is rotatably arranged on the frame 1.

[0026] The rotation of the grinding disc 2 drives the external gear to rotate, and the rotation of the external gear drives the placement disc 3 to move back and forth along the radial direction of the grinding disc 2 through the linear mechanism, so that the workpiece placed in the placement hole 31 is ground. Due to the rotation of the grinding disc 2 and the radial movement of the workpiece, the grinding surface of the workpiece and the grinding disc 2 is increased, the overall utilization rate of the grinding disc 2 is improved, the excessive consumption of the local grinding disc 2 is reduced, the maintenance frequency is reduced, and the production efficiency is effectively improved.

[0027] In an embodiment further provided by the utility model, the linear mechanism includes a rotating gear 22 meshing with the outer gear ring 21, the rotating gear 22 is rotatably connected to the frame 1, and a connecting rod 23 is rotatably connected to the rotating gear 22, a slider 24 is rotatably connected to the end of the connecting rod 23, the slider 24 is slidably connected to the support mechanism, and a placement plate 3 is connected to the slider 24. The rotating gear 22 is rotatably connected to the frame 1 through a rotating shaft (not shown in the figure), a first connecting rod 25 is fixedly connected to the rotating gear 22, and the rotating gear 22 is rotatably connected to the connecting rod 23 through the first connecting rod 25, a second connecting rod 26 is fixedly connected to the slider 24, and the connecting rod 23 is rotatably connected to the slider 24 through the second connecting rod 26.

[0028] In an embodiment further provided by the present invention, the support mechanism comprises a support frame 11 fixedly connected to the frame 1 , and a slide groove 12 corresponding to the slider 24 is provided on the support frame 11 .

[0029] In the embodiment further provided by the utility model, a rotation mechanism is also included, the rotation mechanism includes an L rod 4, a limit rod 41 is fixedly connected to the L rod 4, the L rod 4 is fixedly connected to the placement plate 3, and the L rod 4 is rotatably connected to the slider 24, and a limit groove 13 for sliding the limit rod 41 is provided on the support frame 11.

[0031] Working principle:

[0032] The rotation of the grinding disc 2 drives the outer gear to rotate, and the rotation of the outer gear drives the rotating gear 22 to rotate. The rotation of the rotating gear 22 drives the slider 24 to move along the radial direction of the grinding disc 2 through the connecting rod 23. The movement of the slider 24 drives the synchronous movement of the placement disc 3; and the movement of the slider 24 drives the limiting rod 41 to move synchronously. When the limiting rod 41 slides in the inclined groove 132, it drives the placement disc 3 to rotate through the L rod 4, thereby causing the workpiece located in the placement hole 31 on the placement disc 3 to rotate.

[0033] The grinding machine can realize that the placement disc 3 keeps rotating while moving along the radial direction of the grinding disc 2, thereby increasing the grinding surface of the workpiece and the grinding disc 2, improving the overall utilization rate of the grinding disc 2, reducing the local excessive consumption of the grinding disc 2, reducing the maintenance frequency, and effectively improving production efficiency.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
