Description

Technical field:

[0001] The utility model relates to the technical field of turning tool grinding devices, and more particularly to a tool grinding stand which is convenient for assembly and disassembly. Background technology:

[0002] Existing bearings typically consist of an outer ring, an inner ring, steel balls, and a cage. The inner ring is inserted within the outer ring, with a cage inserted between the two rings. The cage, loaded with an annular arrangement of steel balls, is clamped between the outer and inner rings. The outer and inner rings of a bearing are typically forged into blanks and then machined. Turning is a common machining method for bearing rings, requiring the use of a profiled turning tool. These tools then need to be sharpened. During sharpening, the profiled turning tools are clamped to a grinding station and then sharpened using a grinding machine with a reciprocating grinding wheel. Currently, the tool grinding station has two rows of clamping stations for the profiled turning tools, which are held in place by bolted clamps. Each profiled turning tool has a clamping block, requiring numerous bolts to be tightened during each clamping operation. Therefore, improvements are needed to facilitate the clamping of profiled turning tools. Utility model content:

[0007] Preferably, the width of the knife pressing groove on the knife pressing holder is equal to the width of the knife pressing block, and the height of the knife pressing block is greater than the depth of the knife pressing groove;

[0008] A transverse adjusting groove is formed on the knife pressing block, and an adjusting bolt is inserted into the adjusting groove of the knife pressing block.

[0009] Preferably, the upper end surface of the knife pressing block close to one end of the middle part of the bearing seat is formed with a longitudinal slot, and a longitudinal pressure strip is inserted into the slot, and the pressure strip is against the upper end surface of the knife pressing frame;

Fastening bolt; 4. Tool press block; 41. Adjustment groove; 42. Clamping slot; 5. Adjustment bolt; 6. Pressure strip; 61. Support plate; 62. Guide groove; 7. Screw. Specific implementation method:

[0020] Example: See Figures 1 to 3As shown, a tool sharpening rack with convenient loading and unloading comprises a rectangular supporting seat 1, a longitudinal positioning recess 11 is formed in the middle of the supporting seat 1, and a plurality of longitudinally distributed turning tool placement grooves 12 are respectively formed on the upper end surfaces of the supporting seat 1 on both sides of the positioning recess 11, and a tool pressing rack 2 with a T-shaped cross section is provided above the supporting seat 1, the tool pressing rack 2 comprises an upper horizontal pressing plate 22 and a lower rectangular guide block 21, the guide block 21 is inserted into the positioning recess 11 of the supporting seat 1, and a plurality of tool pressing grooves 23 are formed on the upper end surface of the pressing plate 22 opposite to the turning tool placement grooves 12, and rectangular strip-shaped tool pressing blocks 4 are inserted at both ends of the tool pressing groove 23, and the tool pressing block 4 is fixedly connected to the tool pressing rack 2 by an adjusting bolt 5, and the end of the tool pressing block 4 close to the side of the supporting seat 1 extends out of the tool pressing rack 2 and is located directly above the turning tool placement groove 12;

[0021] A plurality of longitudinally distributed step holes 24 are formed on the knife pressing frame 2 between the knife pressing grooves 23 . Fastening bolts 3 are inserted into the step holes 24 , and the lower ends of the fastening bolts 3 are screwed onto the bearing seat 1 .

[0022] The number of the stepped holes 24 on the knife pressing groove 23 is less than the number of the knife pressing grooves 23, and the distance from the lower end surface of the pressing plate 22 to the lower end surface of the guide block 21 is less than the depth of the positioning recess 11 on the bearing seat 1; the length and width of the guide block 21 are respectively equal to the length and width of the positioning recess 11, and thus the knife pressing holder 2 can only move up and down.

[0023] The width of the knife pressing groove 23 on the knife pressing frame 2 is equal to the width of the knife pressing block 4, and the height of the knife pressing block 4 is greater than the depth of the knife pressing groove 23. The knife pressing block 4 can only move horizontally on the knife pressing frame 2; at the same time, the adjusting bolt 5 will not be interfered with by the upper end surface of the knife pressing frame 2.

[0024] The press block 4 is formed with a transverse adjustment groove 41, and the adjustment bolt 5 is inserted into the adjustment groove 41 of the press block 4. The position of the press block 4 can be adjusted through the adjustment groove 41, so that the end of the press block 4 can be pressed at an effective clamping position for turning forming tools of different sizes.

[0025] The upper end surface of the knife pressing block 4 near the middle end of the bearing seat 1 is formed with a longitudinal slot 42, and a longitudinal pressure strip 6 is inserted into the slot 42, and the pressure strip 6 abuts against the upper end surface of the knife pressing frame 2; without the pressure strip 6, the position of the knife pressing block 4 needs to be moved one by one, while the pressure strip 6 can realize the overall movement of the knife pressing block 4 on one side of the knife pressing frame 2; adjustment is more convenient;

[0026] The pressure strip 6 is formed with a plurality of transverse support plates 61 , and the support plates 61 are formed with transverse guide grooves 62 . Screws 7 are inserted into the guide grooves 62 , and the screws 7 are screwed and fixed to the pressure tool holder 2 .

[0027] The bottom surface of the clamping groove 42 on the knife pressing block 4 is flush with the upper end surface of the knife pressing frame 2, that is, the pressure strip 6 can also constrain the position of the knife pressing block 4 to prevent the knife pressing block 4 from moving.

[0028] The fastening bolt 3 on the knife pressing frame 2 adopts a hexagon socket bolt, and the upper end surface of the fastening bolt 3 is located on the lower side of the upper end surface of the knife pressing frame 2. The fastening bolt 3 is located on the lower side of the pressure strip 6 and will not interfere with the pressure strip 6.

[0029] The turning tool placement grooves 12 are linearly and evenly distributed on the bearing seat 1 , and the tool pressing blocks 4 are linearly and evenly distributed on the tool pressing frame 2 .

[0030] Working principle: This solution is a tool sharpening stand with easy loading and unloading. In the past, when clamping a formed turning tool on the sharpening stand, the height of the tool pressing block 4 can be changed mainly by loosening the adjusting bolt 5, thereby achieving the installation of the formed turning tool into the turning tool placement groove 12, and finally tightening the adjusting bolt 5. Because there are many adjusting bolts 5, the replacement of the formed turning tool on the sharpening stand is relatively cumbersome and time-consuming.

[0031] Furthermore, the present tool sharpening stand is improved, and its tool pressing block 4 is set on the tool pressing stand 2. By loosening the fastening bolts 3, the tool pressing stand 2 can be moved, thereby driving the tool pressing block 4 to move completely; therefore, when clamping the forming turning tool, it is only necessary to loosen or tighten the fastening bolts 3. The number of fastening bolts 3 is small, the operation is convenient, and the forming turning tool can be replaced quickly.

[0032] The embodiments are intended to illustrate the present invention and are not intended to limit the present invention. Any person skilled in the art may modify the embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be as set forth in the claims of the present invention.
