Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, specifically a grinding device for processing a shock absorber piston rod. Background Technology

[0002] During long-term use, the piston rod of the shock absorber will develop scratches, defects, and other damage on its outer wall. When repairing the damage, stainless steel wire welding is used to fill the gaps. After welding, the welded area needs to be ground to keep the outer wall of the piston rod smooth.

[0003] When using a grinder's abrasive wheel for grinding, flying sparks and iron filings can injure the operator. Therefore, existing methods involve installing a protective plate on the outside of the grinder to block the iron filings. However, during the grinding process, in order to ensure the grinding effect, the operator will constantly adjust the angle of the grinder to ensure the smoothness of the grinding area. Since the protective plate is usually made of a fixed-shape material, it will come into contact with the ground when the grinder rotates, thus hindering the rotation of the grinder.

[0004] Therefore, this application provides a grinding device for processing piston rods of shock absorbers to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a grinding device for processing piston rods of shock absorbers, aiming to solve the problems mentioned in the background art, such as the existing grinding machines having external protective plates to block iron filings, but during the grinding process, in order to ensure the grinding effect, the operator will constantly adjust the angle of the grinding machine to ensure the smoothness of the grinding area, and the protective plates are usually made of fixed-shaped plates, so when the grinding machine rotates, the protective plates will come into contact with the ground, thereby hindering the rotation of the grinding machine.

[0006] To achieve the above objectives, this application provides the following technical solution: a grinding device for processing a shock absorber piston rod, comprising a body and a grinding wheel disposed at the output end of the body for grinding;

[0007] To prevent the protective components from affecting the rotation of the machine body: a protective component is installed on the outside of the machine body for protecting against flying iron filings; a mounting ring is installed on the outside of the machine body for mounting the protective component; a connecting component is installed at the top of the protective component for connecting the machine body and the mounting ring; and a mounting block is fixedly installed on the outer wall of the mounting ring for mounting the connecting component. According to the operator's preference, the connecting component is inserted into the mounting block at the corresponding position to fix the mounting ring and the protective component. When the grinding wheel is rotated for grinding, the machine body rotates, and when the movable protective plate contacts the ground, it squeezes the movable mounting plate. Under the action of the bending groove of the movable mounting plate, the movable protective plate rotates, thereby reducing the impact of the movable protective plate on the rotation of the machine body and facilitating the operator's grinding operation of the piston rod.

[0008] Preferably, to facilitate the installation of the mounting ring: the vertical cross-sectional shape of the mounting ring corresponds to the vertical cross-section of the machine body, and the inner wall of the mounting ring is provided with anti-slip texture to prevent the mounting ring from sliding. By fitting the mounting ring onto the outer wall of the machine body, the frictional force exerted by the anti-slip texture on the machine body reduces the sliding of the mounting ring.

[0009] Preferably, for protection against flying metal filings: the protective assembly includes a fixed protective plate disposed on the outside of the machine body to block flying metal filings, movable protective plates symmetrically disposed on both sides of the fixed protective plate to flexibly block flying metal filings, an extension cloth disposed between adjacent movable protective plates to seal gaps, a fixed mounting plate fixedly disposed on the top of the fixed protective plate for mounting the fixed protective plate, and movable mounting plates symmetrically disposed at both ends of the fixed mounting plate for mounting the movable protective plates. Through the fixed protective plate and multiple movable protective plates, protection against flying metal filings is achieved. When the movable protective plate is unfolded, the extension cloth unfolds, thereby preventing metal filings from flying towards the operator from between adjacent movable protective plates and between the fixed and movable protective plates.

[0010] Preferably, to facilitate the rotation of the movable protective plate: the bottom end of the movable mounting plate is provided with a bending groove for bending the movable mounting plate. Through the bending groove, the movable mounting plate can be bent, thereby facilitating the rotation of the movable protective plate.

[0011] Preferably, to facilitate the rotation of the movable protective plate: the bottom end of the movable mounting plate is provided with a bending groove for bending the movable mounting plate. Through the bending groove, the movable mounting plate can be bent, thereby facilitating the rotation of the movable protective plate. By inserting the locking block into the locking hole and fixing the insert block into the insertion groove, the connecting assembly and the mounting block are fixedly installed, thus installing the mounting ring and the protective assembly.

[0012] Preferably, the insert block has a cavity inside, and the inner wall of the cavity has an insertion hole for inserting the locking block.

[0013] Preferably, to facilitate adjustment of the installation position of the protective component: one end of the mounting block is fixedly connected to the outer wall of the mounting ring, and the other end of the mounting block has a insertion groove for inserting the plug, the inner wall of the insertion groove has a locking hole for inserting the locking block. By inserting the connecting component into the mounting block at the corresponding position, the position of the protective component can be changed, making the position of the protective component more adaptable to the operator's working habits.

[0014] This application, through the design of protective components, mounting rings, connecting components, and mounting blocks, allows the connecting components to be inserted into the mounting blocks at corresponding positions according to the operator's preference, thus securing the mounting rings and protective components. When the grinding wheel is rotated for grinding, the machine body rotates, and when the movable protective plate comes into contact with the ground, it will compress the movable mounting plate. Under the action of the bending groove of the movable mounting plate, the movable protective plate will rotate, thereby reducing the impact of the movable protective plate on the rotation operation of the machine body and facilitating the operator's grinding operation of the piston rod.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This embodiment provides a grinding device for machining the piston rod of a shock absorber, such as... Figure 1-6 As shown, the polishing device includes a body 1 and a polishing wheel 2 installed at the output end of the body 1 for polishing.

[0025] To prevent the protective component 3 from affecting the rotation of the machine body 1: a protective component 3 is installed on the outside of the machine body 1 for protection against flying iron filings; a mounting ring 4 is installed on the outside of the machine body 1 for mounting the protective component 3; a connecting component 5 is installed at the top of the protective component 3 for connecting the machine body 1 and the mounting ring 4; and a mounting block 6 is fixedly installed on the outer wall of the mounting ring 4 for mounting the connecting component 5. According to the operator's preference, the connecting component 5 is inserted into the mounting block 6 at the corresponding position to fix the mounting ring 4 and the protective component 3. When the grinding wheel 2 is rotated for grinding, the machine body 1 is rotated, and when the movable protective plate 32 contacts the ground, it will squeeze the movable mounting plate 35. Under the action of the bending groove of the movable mounting plate 35, the movable protective plate 32 rotates, thereby reducing the impact of the movable protective plate 32 on the rotation operation of the machine body 1 and facilitating the operator's grinding operation of the piston rod.

[0026] Furthermore, the machine body 1 and the grinding wheel 2 constitute the existing grinding wheel grinder. The grinding wheel 2 is fixedly connected to the output end of the machine body 1 by screws. During grinding, the machine body 1 is moved to drive the displacement of the rotating grinding wheel 2, thereby completing the grinding of the piston rod.

[0027] Specifically, to facilitate the installation of the mounting ring 4: the vertical cross-sectional shape of the mounting ring 4 corresponds to the vertical cross-section of the body 1, and the inner wall of the mounting ring 4 is provided with anti-slip textures 7 to prevent the mounting ring 4 from sliding. By fitting the mounting ring 4 onto the outer wall of the body 1, the friction of the anti-slip textures 7 on the body 1 reduces the sliding of the mounting ring 4. The inner dimensions of the mounting ring 4 are adapted to the outer dimensions of the body 1. By sliding the mounting ring 4 onto the outside of the gripping part of the body 1, the friction between the anti-slip textures 7 and the outer wall of the body 1 is increased, thus fixing the mounting ring 4 to the outside of the body 1.

[0028] Specifically, for protection against flying metal filings: the protective assembly 3 includes a fixed protective plate 31 disposed on the outside of the machine body 1 to block flying metal filings, movable protective plates 32 symmetrically disposed on both sides of the fixed protective plate 31 to flexibly block flying metal filings, an extension cloth 33 disposed between adjacent movable protective plates 32 to seal gaps, a fixed mounting plate 34 fixedly disposed at the top of the fixed protective plate 31 for mounting the fixed protective plate 31, and movable mounting plates 35 symmetrically disposed at both ends of the fixed mounting plate 34 for mounting the movable protective plates 32. Through the fixed protective plate 31 and multiple movable protective plates 32, protection against flying metal filings is achieved. When the movable protective plate 32 is unfolded, the extension cloth 33 unfolds, thereby preventing metal filings from flying towards the operator from between adjacent movable protective plates 32 and between the fixed protective plate 31 and the movable protective plate 32. Both the fixed protective plate 31 and the movable protective plate 32 are strip-shaped plates, and the extended fabric 33 is a flexible fabric. Multiple movable protective plates 32 are provided and symmetrically distributed at both ends of the fixed protective plate 31. The fixed protective plate 31 is bonded to the contact part of the fixed mounting plate 34. The movable mounting plate 35 is integrally formed with the fixed mounting plate 34. The movable protective plate 32 is bonded to the contact part of the movable mounting plate 35. When there is no external force, the extended fabric 33 is folded. When the movable protective plates 32 move away from each other, the extended fabric 33 unfolds.

[0029] More specifically, to facilitate the rotation of the movable protective plate 32, a bending groove is provided at the bottom end of the movable mounting plate 35 for bending. This bending groove allows the movable mounting plate 35 to be bent, thus facilitating the rotation of the movable protective plate 32. The bending groove can be triangular, allowing the movable mounting plate 35 to bend and the movable protective plate 32 to rotate, preventing direct contact between the movable protective plate 32 and the ground, thereby reducing the impact of the movable protective plate 32 on the rotation of the machine body 1.

[0030] Specifically, to facilitate the connection between the protective component 3 and the mounting ring 4: the connecting component 5 includes a locking block 51 inserted inside the mounting block 6 for connecting the connecting component 5 and the mounting block 6; an insert block 52 fixedly connected to the top of the fixed mounting plate 34 for mounting the locking block 51; a baffle 53 fixedly connected to one end of the locking block 51 for limiting the movement of the locking block 51; and a spring 54 located on the side of the baffle 53 away from the locking block 51 for pushing the baffle 53. The insert block 52 has a cavity inside, and the inner wall of the cavity has an insertion hole for inserting the locking block 51. By inserting the locking block 51 into the locking hole and fixing the insert block 52 in the insertion slot, the connecting component 5 and the mounting block 6 are fixedly installed, thus installing the mounting ring 4 and the protective component 3. The bottom end of the insert 52 is bonded to the top end of the fixed mounting plate 34. The through hole is adapted to the size of the locking block 51. The size of the baffle 53 is 1.2 times the size of the through hole. Both the baffle 53 and the spring 54 are set in the cavity. The spring 54 is always in a compressed state in the cavity.

[0031] More specifically, to facilitate adjustment of the installation position of the protective component 3: one end of the mounting block 6 is fixedly connected to the outer wall of the mounting ring 4, and the other end of the mounting block 6 has a slot for inserting the insert block 52. The inner wall of the slot has a locking hole for inserting the locking block 51. By inserting the connecting component 5 into the mounting block 6 at the corresponding position, the position of the protective component 3 can be changed to better suit the operator's working habits. Multiple mounting blocks 6 are provided, evenly spaced and arc-shaped distributed on the outer wall of the mounting ring 4. By inserting the connecting component 5 into the mounting blocks 6 at different positions, the position of the protective component 3 can be adjusted, facilitating protection for users with different operating preferences. The size of the slot matches the size of the insert block 52, and the size of the locking hole matches the size of the insertion hole. The contact parts of the mounting block 6 and the mounting ring 4 are bonded and fixed.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
