[0028] like Figure 1-8As shown, a double-sided repair mechanism 10 of a grinding wheel dresser for an H-shaped steel saw blade grinding machine of the present application is provided, comprising: a repair rod 11 and a screw rod 12. The repair rod 11 comprises: a flat portion 111 and a cylindrical section 112. The outer diameter of the cylindrical section 112 of the repair rod 11 is 32 mm, and the outer surface roughness is Ra0.8 um. Such a design can reduce the friction with the surface of the mating part. A connecting hole 113 is formed on the flat portion 111, and the connecting hole 113 is used to install the connecting plate 13. The connecting plate 13 is divided into an outer connecting plate 13 and an inner connecting plate 13. A mounting hole 131 is formed at the right end of each connecting plate 13, and the mounting hole 131 is used to be installed on the flat portion 111. The diameter of the mounting hole 131 is 10 mm, and this size matches the fixing bolt 161. The right end of the connecting plate 13 is fixedly connected to the flat portion 111 through a fixing assembly 16. The fixing assembly 16 comprises: a fixing bolt 161 and a limiting step 162. The fixing bolt 161 is an M10 bolt. The outer diameter of the connection part of the fixing bolt 161 is 10mm, which forms a rotatable clearance fit with the repair rod 11. At the same time, after the connecting plate 13 is connected to the fixing bolt 161, it is ensured that there is only a small swing in the mounting hole 131. The left end of the connecting plate 13 is formed with a fixing hole 132 for fixing the diamond pen. The diameter of the fixing hole 132 is 13mm, which is used to install the fixing diamond pen bolt 17. This size matches the fixing diamond pen bolt 17. The diamond pen is connected to the connecting plate 13 by screwing the fixing diamond pen bolt 17 into the fixing hole 132. The right side of the fixing diamond pen bolt 17 is a square head, which is used to be installed in the slide plate on the sliding seat of the diamond pen propulsion mechanism, effectively preventing the rotation of the fixing diamond pen bolt 17, and ensuring that the diamond pen is always aligned with the grinding wheel direction. The left end of the fixing diamond pen bolt 17 is provided with a thread, which connects the connecting plate 13 with the fixing diamond pen bolt 17. The middle section of the fixing diamond pen bolt 17 is a pin 171, which is used to connect the mounting assembly 18. The length of the pin 171 is 17.5 mm. This design is because the sum of the thicknesses of the mounting assembly 18 and the connecting plate 13 is 18 mm. Designing the length of the pin 171 to be 17.5 mm can prevent the pin 171 from interfering with the tightening of the nut. The mounting assembly 18 includes a support plate 181, a V-shaped notch 182, two guide grooves 183, two slide seats, and four threaded hole groups 184. A V-shaped notch 182 is formed on one side of the support plate 181, and the angle of the V-shaped notch 182 is 60°. Two guide grooves 183 are arranged on the support plate 181 and are respectively located on the upper and lower sides of the V-shaped notch 182. The extension direction of the guide groove 183 is parallel to the extension direction of the upper and lower sides of the V-shaped notch 182. The threaded hole group 184 is arranged on both sides of the extension direction of the two guide grooves 183 on the support plate 181. The slide seat is installed on the threaded hole group 184. The angle between the two guide grooves 183 is 60°. The threaded hole group 184 near the V-shaped notch 182 is composed of five screw holes 185. The threaded hole group 184 far from the V-shaped notch 182 is composed of six screw holes 185.When the connecting plate 13 is pushed forward, it drives the fixed diamond pen bolt 17 to move forward, and the fixed diamond pen bolt 17 drives the upper and lower slide seats to run along the guide groove 183 with an angle of 60° on the support plate 181 and the slide plates of the upper and lower slide seats installed on the guide groove 183, so as to perform reciprocating repairing motion on the grinding wheel. A threaded hole 114 is provided in the cylindrical section 112, and the right end of the threaded hole 114 is connected to the right end surface of the cylindrical section 112. The left end of the cylindrical section 112 is installed in the bushing of the diamond pen propulsion mechanism, and is in clearance fit with the bushing. The repair rod 11 can move axially in the bushing, and at the same time, the bushing has a radial supporting effect on the diamond pen repair rod 11. The screw rod 12 includes: a first threaded section 121, a limiting section 122, a bearing stop 123, a second threaded section 124 and a handwheel stop 125. One end of the first threaded section 121 is threadedly installed in the repair rod 11 through the threaded hole 114. One end of the first threaded section 121 extending out of the repair rod 11 is connected to one end of the limit section 122. The other end of the limit section 122 is connected to a bearing stopper 123 for sleeve bearings. The outer ring of the bearing is fixed to the propulsion mechanism by a locking nut to ensure that the bearing does not move axially when the feed screw 12 rotates to propel the repair rod 11. One end of the second threaded section 124 is connected to the end of the bearing stopper 123 away from the limit section 122 for installing a threaded cap. When the inner ring of the bearing is installed on the screw 12, the threaded cap is screwed on to press the inner ring of the bearing of the screw 12, so that the screw 12 does not move axially relative to the bearing. The other end of the second threaded section 124 is connected to a handwheel stopper 125 for installing a handwheel. The outer cylindrical surface of the handwheel stopper 125 is formed with a keyway 19 that matches the handwheel keyway 19 to ensure that the screw 12 rotates synchronously with the handwheel when the handwheel is turned. The rightmost end face of the screw 12 is provided with a bolt hole 20 for installing a hexagonal bolt. A gasket is provided between the hexagonal bolt and the bolt hole 20. The gasket is screwed into the bolt hole 20 through the hexagonal bolt and abuts against the hand wheel to prevent the hand wheel from slipping axially.

[0029] As a further solution, the fixing bolt 161 penetrates and is inserted into the connecting hole 113 and the mounting hole 131 to fix the connecting plate 13 to the flat portion 111. A limiting step 162 is formed below the fixing bolt 161 to limit the axial movement of the connecting plate 13. The limiting step 162 has a thickness of 2 mm and is used to limit the axial movement of the connecting plate 13.

[0030] As a further solution, a circular boss 141 is formed at the left end of the outer connecting plate 13. The thickness of the circular boss 141 is 3 mm. This is to make room for the 3 mm thickness of the inner connecting plate 13, to ensure that the step surface at the left end of the outer connecting plate 13 can also run close to the plane of the support plate 181 of the diamond pen propulsion mechanism, and to ensure the overall rigidity of the repair mechanism when repairing the grinding wheel.

[0031] As a further solution, the width of the connecting plate 13 is 16 mm and the thickness is 3 mm. The hole spacing between the mounting hole 131 and the fixing hole 132 on the connecting plate 13 is 62 mm. The connecting plate 13 is designed in this way because the repair size of the grinding wheel is 30 mm and the connecting bolts at both ends of the connecting plate 13 require a certain space.

[0032] As a further solution, the length of the flat portion 111 is 18.5 mm, which meets the rotation space required for installing the connecting plate 13. The length of the cylindrical section 112 is 164 mm, which meets the length requirement for threaded transmission with the screw rod 12. The threaded hole 114 is divided into a neutral inner hole 116 and a small threaded hole 115 that is threadedly matched with the screw rod 12. The diameter of the small threaded hole 115 is 16 mm, the length is 25 mm, and the pitch is 4 mm. The length of the small threaded hole 115 is 25 mm to meet the long-term use requirements of the small threaded hole 115. The diameter of the neutral inner hole 116 is 20 mm, and the length is 125 mm. The diameter of the neutral inner hole 116 is designed to be 20 mm to avoid interference with the screw rod 12.

[0033] As a further solution, the spiral direction of the screw 12 is left-handed. This is because the staff is accustomed to the screw 12 rotating in a clockwise direction. The diameter of the screw 12 is 16 mm and the pitch is 4 mm. This is to meet the feed amount of the diamond pen repair grinding wheel and the rotation frequency of the staff operation.

[0034] As a further solution, the length of the first thread segment 121 is 83 mm, which is based on the fact that the length of the reciprocating repair grinding wheel of the repair rod 11 is 45 mm, the length of the small threaded hole 115 is 25 mm, etc. The length of the bearing stopper 123 is 12 mm, and the outer diameter is 17 mm, which matches the bearing size. The length of the second thread segment 124 is 10 mm, which matches the size of the thread cap. The length of the handwheel stopper 125 is 15 mm, and the outer diameter is 12 mm, which matches the size of the installation part of the handwheel.

[0035] As a further solution, the keyway 19 has a length of 10 mm, a width of 3 mm, and a height of 2 mm, which matches the keyway 19 on the handwheel.

[0036] The method for repairing a saw blade grinding wheel using a double-sided repair mechanism 10 of an H-shaped steel saw blade grinding machine tool grinding wheel dresser is as follows: rotate the hand wheel to drive the first threaded segment 121 on the screw rod 12 to form a threaded transmission with the threaded hole 114 in the repair rod 11, and the screw rod 12 drives the repair rod 11 to reciprocate, thereby driving the diamond pen fixed on the connecting plate 13 to move up and down along the slide seat at an angle of 60°, thereby completing the precise repair work of the upper and lower surfaces of the grinding wheel at 60°.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
