[0002] In some industrial production lines, H-shaped steel is cut to length using saw blades during the rolling process. After the saw blade has been used for a period of time, the saw blade will gradually become blunt. This will greatly reduce the cutting efficiency and increase the load on the sawing machine, so the saw blade needs to be sharpened. In the work of sharpening the saw blade, after the grinding wheel for sharpening the saw blade has been used for a period of time, the abrasive grains of the grinding wheel become blunt due to long-term use. The grinding efficiency of the blunt grinding wheel is low and the grinding force becomes larger. For this reason, the saw blade sharpening process requires the repair of the blunt grinding wheel. At present, the method of repairing the saw blade grinding wheel is to repair the grinding wheel with a manual handheld grinding wheel repair block. This repair method has great safety hazards and is likely to cause serious consequences such as hand injuries to the operator. In addition, the control of the angle during the manual repair process is not accurate enough, which may cause errors. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0022] like Figure 1-2As shown, a grinding wheel dressing propulsion mechanism 10 of an H-shaped steel saw blade dressing machine of the present application includes: a propulsion rod 11 and a support plate 12. The propulsion rod 11 includes: a large outer diameter sleeve 111, an intermediate cylindrical section 113 and a trapezoidal thread section 115. An open groove 112 is formed at one end of the large outer diameter sleeve 111, and the open groove 112 is used to insert the welding support plate 12. The width value of the open groove 112 is 8 mm, which is consistent with the thickness value of the support plate 12. One end of the intermediate cylindrical section 113 is fixedly connected to the other end of the large outer diameter sleeve 111. An inner hole 114 is formed inside the intermediate cylindrical section 113 for installing the bushing 13. A stop threaded hole is formed on the outer periphery of the intermediate cylindrical section 113, and the stop screw is screwed into the stop threaded hole to fix the bushing 13 to the inner hole 114 to prevent the bushing 13 from moving axially. The bushing 13 can play a role of radial support, making the propulsion mechanism more stable. One end of the trapezoidal thread segment 115 is connected to the other end of the middle cylindrical segment 113. An idle inner hole 116 is formed inside the trapezoidal thread segment 115. One end of the step 117 is connected to the other side of the idle inner hole 116. An inner cavity 118 is formed inside the trapezoidal thread segment 115 at the other end of the step 117, which is used to install the bearing 14. The trapezoidal thread segment 115 is formed with an internal threaded hole 119 at one end close to the bearing 14, and the internal threaded hole 119 is used to screw the threaded cap. One side of the threaded cap contacts the outer ring of the bearing 14, and together with the step 117, the bearing 14 is laterally locked. This can prevent the repair mechanism connected to the bearing 14 from moving axially, making the entire device more stable. The support plate 12 is welded and fixed to the open groove 112. The height value of the support plate 12 is 198mm, the width value is 78.28mm, and the thickness value is 8mm. The size design of the support plate 12 meets the installation requirements, so that the support plate 12 is sufficiently stable after being welded on the large outer diameter sleeve 111. A connecting component 121 is provided on the support plate 12, and the connecting component 121 is used to connect the repair mechanism.

[0023] As a further solution, the outer diameter of the middle cylindrical section 113 is 52 mm, so that the middle cylindrical section 113 forms a clearance fit with the fixing sleeve of the fixing mechanism. In this way, the fixing sleeve plays a radial supporting role for the propulsion rod 11, restricting the radial movement of the propulsion rod 11 in the fixing sleeve, and also restricting the radial swing of the propulsion rod 11 on the fixing sleeve.

[0024] As a further solution, the outer diameter of the bushing 13 is 40 mm and the length is 60 mm. The diameter of the inner hole 114 is 40 mm. Since the outer diameter of the bushing 13 is less than or equal to the diameter of the inner hole 114, the bushing 13 and the inner hole 114 form a transition fit. This also makes it easier for the bushing 13 to be installed on the inner hole 114.

[0025] As a further solution, the large outer diameter sleeve 111 is in the shape of a ring. The outer diameter of the large outer diameter sleeve 111 is 114 mm, and the inner diameter is 100 mm. The outer diameter is 114 mm because the contact length of the large outer diameter sleeve 111 and the support plate 12 when welded is 114 mm. The larger contact length ensures the stability and firmness of the support plate 12 after welding. The inner diameter is 100 mm because the bushing 13 needs to be installed in the inner hole 114 of the middle cylindrical section 113, which better matches the size of the bushing 13.

[0026] As a further solution, the diameter of the inner cavity 118 is 40 mm, and the outer diameter of the bearing 14 is 40 mm. The bearing 14 forms a transition fit with the inner cavity 118 to ensure a secure connection between the bearing 14 and the inner cavity 118. The inner ring of the bearing 14 is used to install the repair mechanism screw rod, which is screwed with a thread and pressed against the inner ring of the bearing 14 by a cap, so that the repair mechanism screw rod will not move axially relative to the bearing 14.

[0027] As a further solution, the diameter of the step 117 is 30 mm and the length is 2 mm. The step 117 and the threaded cap contact the outer ring of the bearing 14 to axially lock the bearing 14, thereby ensuring the stability of the device.

[0028] 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.
