Description

Technical Field

[0001] The utility model relates to the technical field of screw rod trimming, in particular to a diamond roller used for screw rod trimming. Background Art

[0002] The screw is a kind of precision part commonly used in mechanical engineering, and its main function is to convert rotational motion into linear motion. One end of the screw has a thread and is sleeved with a nut. When the screw rotates, the nut will move to achieve linear motion. There are many types of screws. According to different materials, they can be divided into steel screws, aluminum screws, copper screws, cast iron screws, etc. The processing technology of screws mainly includes cold processing, heat treatment, surface treatment and inspection. Cold processing processes the screw through stamping, stretching, forging and other methods to ensure its accuracy and appearance. Heat treatment is to process the screw at high temperature to enhance its strength. Surface treatment technologies such as polishing, galvanizing, electroplating, etc. can make the surface of the screw smoother. Among them, screw finishing is an important step in the surface treatment of the screw.

[0003] For example, the Chinese patent "A Disc Diamond Roller" with announcement number CN217097279U includes an upper positioning clamping assembly, a lower positioning clamping assembly is detachably mounted on the bottom of the upper positioning clamping assembly, a diamond roller sheet is detachably mounted between the upper positioning clamping assembly and the lower positioning clamping assembly, a fixing bolt is embedded in the interior of the upper positioning clamping assembly, the upper positioning clamping assembly includes a metal connecting block, a connecting ring is fixedly mounted on the top of the metal connecting block, an upper fixed rack is fixedly mounted inside the connecting ring, and the outer surface of the connecting ring A positioning rod is fixedly installed on the surface, an upper heat dissipation hole is opened inside the metal connecting block, an upper bolt hole is opened inside the metal connecting block, the number of the fixing bolts is four, and the fixing bolts are detachably installed inside the upper bolt holes, a buffer friction pad is fixedly installed on the bottom of the metal connecting block, a star-shaped embedding block is fixedly installed on the bottom of the metal connecting block, the diamond roller sheet includes a shaping sheet, the upper and lower ends of the shaping sheet are opened with embedding grooves corresponding to the metal connecting block, and the embedding groove is opened inside with a star-shaped groove corresponding to the star-shaped embedding block.

[0004] Although the above-mentioned prior art can realize the trimming of the screw, in actual use, on the one hand, the diamond roller is difficult to disassemble and assemble quickly. When the surface of the diamond roller is worn after long-term use, the entire fixed structure needs to be dismantled for replacement, resulting in cumbersome disassembly and assembly steps, thereby affecting the efficiency of the screw trimming operation. On the other hand, the diamond roller does not dissipate heat sufficiently. After the diamond roller is used for a long time, a large amount of heat will be generated. The heat accumulates on the diamond roller, causing thermal cracks or increased wear on the surface of the diamond roller, thereby shortening the service life of the diamond roller. Therefore, it does not meet the existing needs. In this regard, we propose a diamond roller for screw trimming. Utility Model Content

[0005] The purpose of the utility model is to provide a diamond roller for screw rod dressing, so as to solve the problems proposed in the above background technology that the diamond roller is difficult to quickly disassemble and assemble, when the surface of the diamond roller is worn after long-term use, the entire fixing structure needs to be dismantled when it is replaced, and the diamond roller does not dissipate heat sufficiently, so a large amount of heat will be accumulated on the diamond roller after long-term use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a diamond roller for screw rod dressing, comprising a driving rod, wherein two driving rods are provided, a diamond roller is provided between the driving rods on both sides, and the diamond roller is spiral-shaped; and further comprising:

[0007] A limiting groove is arranged inside the driving rod, a limiting block is arranged inside the limiting groove, and the limiting block extends to a side of the driving rod close to the diamond roller.

[0008] Preferably, a first threaded hole is provided at a middle position inside the limit block, and second threaded holes are provided at the front and rear ends inside the drive rod, and the positions of the second threaded holes correspond to those of the first threaded holes.

[0009] Preferably, a threaded rod is provided at the rear end of the limit block, and one end of the threaded rod passes through the first threaded hole and extends to the second threaded hole close to the front end.

[0010] Preferably, a heat dissipation groove is provided inside the groove of the diamond roller, and the heat dissipation groove is spiral-shaped.

[0011] Preferably, a plurality of heat dissipation holes are arranged inside the diamond roller, the heat dissipation holes are distributed in an annular shape with equal intervals, and the heat dissipation holes are connected to the heat dissipation grooves.

[0012] Preferably, four notches are arranged on the outside of the diamond roller, and the notches are distributed equidistantly in a ring shape.

[0013] Preferably, a mounting rod is fixedly provided on one side of the limit block located outside the driving rod, and the mounting rod and the diamond roller are an integrated structure.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model can quickly disassemble and assemble the diamond roller through the limit block and the threaded rod. When the diamond roller is worn out after long-term use, the threaded rod is rotated at this time, and the threaded rod is moved outward through the external thread. During the movement of the threaded rod, it is sequentially moved out of the second threaded hole and the first threaded hole until the threaded rod is disengaged from the driving rod. At this time, the diamond roller is pulled upward to remove the diamond roller from the driving rod. At this time, the limit block on the new diamond roller is aligned with the limit groove opening on the driving rod and the limit block is pushed into the limit groove, and the threaded rod is reinserted into the second threaded hole and the threaded rod is rotated to make the threaded rod pass through the first threaded hole and move to the second threaded hole on the other side, so that the threaded rod is fixed to the limit block through the thread clamping, thereby simplifying the disassembly and assembly steps of the diamond roller, thereby improving the efficiency of the screw rod dressing operation.

[0016] 2. The utility model can accelerate the heat dissipation of the diamond roller through the heat dissipation grooves and the heat dissipation holes. When the diamond roller is in use, the diamond roller is constantly in contact and friction with the screw rod, and the heat generated by the friction is accumulated on the diamond roller. At this time, the heat dissipation grooves and the heat dissipation holes on the diamond roller can increase the contact area between the diamond roller and the air. At the same time, the heat dissipation holes are connected with the heat dissipation grooves, so that the inside of the diamond roller is in direct contact with the air, which accelerates the heat dissipation from the inside of the diamond roller. At this time, during the rotation of the diamond roller, the friction and trimming debris on the screw rod is directly discharged from the heat dissipation groove, which improves the heat dissipation efficiency of the diamond roller and avoids the situation where the debris is directly squeezed with the screw rod when the screw rod is trimmed, causing scratches and grooves on the screw rod surface.

[0017] 3. The utility model can extend the service life of the diamond roller by providing the notch. During the use of the diamond roller, the wear and fall of the diamond abrasive particles will cause the surface of the diamond roller to be uneven, thereby causing stress concentration. The notch can disperse the stress during the processing of the diamond roller, reducing the fatigue damage of the diamond roller caused by continuous high-intensity work, thereby extending the service life of the diamond roller and reducing the maintenance cost of the diamond roller.

[0025] The limiting groove 5 is arranged inside the driving rod 1 . The limiting block 3 is arranged inside the limiting groove 5 , and the limiting block 3 extends to a side of the driving rod 1 close to the diamond roller 7 .

[0026] During use, the diamond roller 7 will be worn out after long-term use. At this time, the threaded rod 4 is rotated, and the threaded rod 4 is moved outward through the external thread. During the movement, the threaded rod 4 is moved out of the second threaded hole 10 and the first threaded hole 6 in turn until the threaded rod 4 is disengaged from the driving rod 1. At this time, the diamond roller 7 is pulled upward again to remove the diamond roller 7 from the driving rod 1. At this time, the limit block 3 on the new diamond roller 7 is aligned with the opening of the limit groove 5 on the driving rod 1 and the limit block 3 is pushed into the limit groove 5, and then the threaded rod 4 is reinserted into the second threaded hole 10 and the threaded rod 4 is rotated to make the threaded rod 4 pass through the first threaded hole 6 and move to the second threaded hole 10 on the other side, so that the threaded rod 4 is fixed to the limit block 3 through the threaded clamping, thereby simplifying the disassembly and assembly steps of the diamond roller 7, thereby improving the efficiency of the screw rod dressing operation.

[0027] See also Figure 2 and Figure 4 A first threaded hole 6 is provided at the middle position inside the limit block 3, and second threaded holes 10 are provided at the front and rear ends inside the driving rod 1, and the second threaded hole 10 corresponds to the position of the first threaded hole 6, so that the limit block 3 can be fixed in the limit groove 5 through the second threaded hole 10 and the first threaded hole 6.

[0028] See also Figure 2 and Figure 4 A threaded rod 4 is provided at the rear end of the limit block 3, and one end of the threaded rod 4 passes through the first threaded hole 6 and extends to the second threaded hole 10 near the front end, so that the diamond roller 7 can be fixed by cooperating with the threaded rod 4, the second threaded hole 10 and the first threaded hole 6.

[0029] See also Figure 1 A heat dissipation groove 8 is arranged inside the groove of the diamond roller 7, and the heat dissipation groove 8 is spiral, so as to increase the contact area between the diamond roller 7 and the air through the heat dissipation groove 8 and improve the heat dissipation effect of the diamond roller 7.

[0030] See also Figure 2 and Figure 3 A plurality of heat dissipation holes 9 are arranged inside the diamond roller 7. The heat dissipation holes 9 are distributed in an annular shape and are equidistantly arranged. The heat dissipation holes 9 are connected with the heat dissipation grooves 8, so that the inside of the diamond roller 7 can be in direct contact with the air through the heat dissipation holes 9 and the heat dissipation grooves 8, thereby improving the heat dissipation efficiency of the diamond roller 7.

[0031] See also Figure 1 and Figure 3 Four notches 11 are arranged on the outside of the diamond roller 7 , and the notches 11 are distributed in an annular shape and at equal intervals, so as to extend the service life of the diamond roller 7 and reduce the maintenance cost of the diamond roller 7 .

[0033] Working principle: When the diamond roller 7 is in use, the diamond roller 7 is constantly in contact and friction with the screw rod, and the heat generated by the friction is accumulated on the diamond roller 7. At this time, the heat dissipation grooves 8 and heat dissipation holes 9 on the diamond roller 7 can increase the contact area between the diamond roller 7 and the air. At the same time, the heat dissipation holes 9 are connected to the heat dissipation grooves 8, so that the inside of the diamond roller 7 is in direct contact with the air, which accelerates the heat dissipation from the inside of the diamond roller 7. At this time, during the rotation of the diamond roller 7, the friction and trimming debris on the screw rod is directly discharged from the heat dissipation grooves 8, which improves the diamond roller 7. The diamond roller 7 improves the heat dissipation efficiency and avoids the situation that the debris is directly squeezed with the screw rod during the trimming of the screw rod, causing scratches and grooves on the surface of the screw rod. During the use of the diamond roller 7, the wear and fall of the diamond abrasive particles will cause the surface of the diamond roller 7 to be uneven, thereby generating stress concentration. Through the provided notch 11, the diamond roller 7 can disperse the stress during the processing, reduce the fatigue damage of the diamond roller 7 caused by continuous high-intensity work, thereby extending the service life of the diamond roller 7 and reducing the maintenance cost of the diamond roller 7.
