DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.
[0021] Reference Figure 1-Figure 3 A tool holder for a special knife sharpener for bearings comprises a base 1, a bracket 4 is slidably connected to the base 1, a rotating shaft 3 is rotatably installed on the bracket 4, a plurality of fixed knife seats 5 and a plurality of fixed frames 8 are fixedly connected to the rotating shaft 3, an I-shaped block 11 is slidably installed in each fixed frame 8, a sliding knife seat 6 is fixedly connected to one side of the I-shaped block 11, and a plurality of I-shaped blocks 11 are connected by rectangular rods 7, a limiting component is arranged on one of the fixed frames 8, the limiting component comprises a sliding rod 15 slidably installed on the fixed frame 8, the cross section of the sliding rod 15 is L-shaped, a through hole 16 for connecting the rectangular rod 7 is opened on the sliding rod 15, a pressure strip 12 is fixedly connected to the sliding rod 15, and the surface of one of the sliding knife seats 6 is in contact with the surface of the pressure strip 12.
[0022] A curved rubber block 14 is fixedly connected to the surface of one side of one of the sliding knife seats 6, and the surface of the curved rubber block 14 fits with the surface of the pressure strip 12. A first spring 13 is sleeved on the sliding rod 15, and one end of the first spring 13 is fixedly connected to the sliding rod 15, and the other end of the first spring 13 is fixedly connected to the fixed frame 8. When the force applied to the sliding rod 15 is removed, under the elastic force of the first spring 13, the sliding rod 15 will move toward the fixed frame 8 until the surface of the pressure strip 12 fits with the upper surface of the sliding knife seat 6. At this time, the surface of the curved rubber block 14 is tightly attached to the surface of the pressure strip 12, and one end of the rectangular rod 7 is inserted into the through-opening 16. The friction between the curved rubber block 14 and the pressure strip 12 is relatively large, which can effectively prevent the through-opening 16 from separating from the rectangular rod 7.
[0023] The cross-section of each fixed frame 8 is in the shape of a U-shaped letter "U", and each fixed frame 8 is fixedly connected to a second spring 9, which is fixedly connected to an I-shaped block 11. The sliding rod 15 is pulled to separate it from the rectangular rod 7. Under the elastic force of each second spring 9, each sliding knife seat 6 will move in a direction away from the fixed knife seat 5.
[0024] A servo motor is fixedly installed on the bracket 4, and the driving end of the servo motor is fixedly connected to the rotating shaft 3. A hydraulic cylinder 10 is fixedly installed on the base 1, and the driving end of the hydraulic cylinder 10 is fixedly connected to the bracket 4. A storage frame 2 is provided on one side of the base 1, and a foam pad is fixedly connected to the inner wall of the storage frame 2. The hydraulic cylinder 10 drives the bracket 4 to move toward the storage frame 2. After the bracket 4 moves to a suitable position, the servo motor drives the rotating shaft 3 to rotate a certain angle, and each fixed knife seat 5 tilts downward at the same time. The blades on each fixed knife seat 5 will fall into the storage frame 2 for collection under the action of gravity, and the foam pad has a good buffering effect on the falling of the blade.
[0025] The first spring 13 is used to move the plurality of blades 12 and 13 toward the rear of the tool holder 8. The first spring 13 is used to move the plurality of blades 12 toward the rear of the tool holder 8. The first spring 13 is used to move the plurality of blades 12 toward the rear of the tool holder 8. The first spring 13 is used to move the plurality of blades 12 toward the rear of the tool holder 8.
[0026] When it is necessary to take out the blade, pull the sliding rod 15 to disengage it from the rectangular rod 7. Under the elastic force of each second spring 9, each sliding knife seat 6 will move away from the fixed knife seat 5. Then the bracket 4 moves to a suitable position, and the rotating shaft 3 rotates a certain angle. The blades on each fixed knife seat 5 will fall into the storage frame 2 for collection under the action of gravity. The operation of fixing and removing the blade is convenient and quick, and the operation time is short, which is conducive to the use of the knife holder.
[0027] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
