The first bolt 3 is rotated to contact the end surface of the lower oilstone clamp 6, and applies a downward force to the lower oilstone clamp 6, so that the lower oilstone clamp 6 is fastened in the oilstone clamping groove 4. The embedded lower oilstone clamp 6 partially enters the upper oilstone clamp 5, and the periphery of the oilstone 1 is clamped in the oilstone clamp assembly 14.

The size of the oilstone upper clamp 5 is 40mm in inner width and 54mm in outer width; the height is 15mm, the length of the square hole 7 is 5mm, and the width of the square hole 7 is 5mm; the inner width of the oilstone lower clamp 6 is 42mm, the outer width is 52mm, and the height is 20mm. The two ends of the lower oilstone clamp 6 are respectively nested with the square holes 7 of the upper oilstone clamp 5 to form an oilstone clamp assembly 14, and the oilstone clamp assembly 14 is applicable to the oilstone 1 with the length, width and height of 40x20x20 mm.

If the second bolt holes formed in the oilstone upper clamp 5 are round holes, the utility model can be applied to the oilstones 1 with different heights, the oilstone upper clamp 5 mainly plays a role in covering protection, the oilstone upper clamp 5 can move up and down according to the different heights of the oilstones 1, and the universality of the clamp assembly is improved.

The contact parts of the upper oilstone clamp 5 and the lower oilstone clamp 6 and the oilstone 1 are respectively provided with an anti-slip pad, and the contact parts of the inside of the oilstone clamping groove 4 and the oilstone clamp assembly 14 can also be provided with an anti-slip pad. Increasing the friction of the whetstone clamp assembly 14 prevents the whetstone 1 from sliding under the force of the trimming tool.

The oilstone 1 is arranged on two sides of the oilstone mounting seat 2, so that double-sided trimming of the grinding wheel can be realized, and the efficiency of trimming is improved.

As shown in fig. 6, the present utility model further includes a measurement assembly comprising a single probe assembly 9 and a double probe assembly 10. The single probe assembly 9 and the double probe assembly 10 are all the prior art in the square polishing and grinding integrated machine, and can automatically measure the thickness of the oilstone 1.

Two probes of the double probe 16 are disposed at both ends of the double probe holder 18 near the side of the oilstone 1, and the single probe 15 is disposed at the center of the single probe holder 17 near the side of the other oilstone 1. That is, the shape of the line connecting the apexes of the two probes of the single probe 15 and the double probe 16 is isosceles triangle, but it is required that it is right triangle. The thickness of the whetstone 1 needs to be corresponding to the center position of the whetstone 1, and then automatic control measurement is realized, because the single probe seat 17 and the double probe seat 18 are symmetrically arranged, if the single probe 15 side corresponds to the center position of one whetstone 1, the other double probe 16 side cannot correspond to the center position of the whetstone 1, and thus the thickness of the whetstone 1 on the double probe 16 side cannot be automatically measured through the probes. Most of the squaring and polishing integrated machines in the prior art are single-side trimming cutters, namely only one oilstone 1 trims a grinding wheel, if double-sided trimming cutters are adopted, the thickness of the double-probe 16 side can only be manually measured by manually entering the squaring and polishing integrated machine, and the manual measurement is poor in safety and labor and time consuming. Therefore, the utility model sets the oilstone clamping grooves 4 on two sides in a staggered way, and sets the overlooking section of the oilstone mounting seat 2 into an L shape, thereby facilitating the staggered arrangement of the oilstone clamping grooves 4, and as shown in fig. 8, enabling one probe in the double-probe assembly 10 to correspond to the center of the oilstone 1, and facilitating the automatic measurement of the oilstones on two sides. For example, if the distance between the two probes of the double probes 16 and the central axis is 7cm, the opening position of the oilstone clamping groove 4 on the side of the double probes 16 is moved forward or backward by 7cm, so that any one of the probes of the double probes 16 corresponds to the center of the oilstone 1.

The tool is directly arranged on the clamping head 11 of the silicon rod 12 in the square grinding and polishing integrated machine, a base is not required to be additionally arranged, the tool repairing is convenient, the structure is simple, and the cost is saved. The grinding machine also comprises a silicon rod 12 and a table top 13, wherein the silicon rod 12 is placed on the table top 13, the pressing head 11 moves downwards to press the silicon rod 12 with a certain pressing force, so that the silicon rod 12 is ensured not to displace in the grinding process.

As shown in fig. 1, the bottom of the oilstone mounting seat 2 is provided with a notch, and the notch is clamped on the pressing head 11. The contact area of the oilstone installation seat 2 and the clamping head is further enlarged due to the arrangement of the notch, and the stability of the oilstone installation seat 2 is further enhanced. The number of the second bolts 8 is three, and the connecting lines of the second bolts are isosceles triangles. Because triangle-shaped has stability, isosceles triangle's setting has further increased the stability of whetstone mount pad 2, prevents that whetstone 1 mount pad from being unstable when repairing the sword.

The inner hexagon screw has six bearing surfaces, has bigger bearing capacity than the straight screw and the cross screw which only have two surfaces, and the whole nut of the inner hexagon screw is sunk into the workpiece, so that the smoothness and the aesthetic property of the surface of the workpiece can be maintained.

And the two end surfaces of the oilstone lower clamp 6 are provided with third bolt holes, and the first bolts 3 are in threaded connection with the third bolt holes. The contact surface of the first bolt 3 and the oilstone lower clamp 6 is prevented from sliding in the process of repairing the cutter.

The oilstone clamp assembly 14 is made of stainless steel. Stainless steel has good corrosion resistance and prevents the abrasive dust from corroding the oilstone clamp assembly 14.

The working principle of the utility model is as follows:

the oilstone 1 is firstly arranged in the oilstone upper clamp 5, and then the oilstone upper clamp 5 is nested with the oilstone lower clamp 6, namely, two ends of the oilstone lower clamp 6 extend into square holes 7 at two ends of the oilstone upper clamp 5. And then the oilstone clamp assembly 14 is integrally placed in the oilstone clamping groove 4, and the first bolt 3 sequentially passes through the first bolt hole, the second bolt hole and the third bolt hole to realize the threaded connection with the third bolt hole.
