Description

Technical Field

[0001] The utility model relates to the technical field of plane processing devices, in particular to a machined plane grinding auxiliary device. Background Art

[0002] During product machining, due to technical limitations in blank manufacturing and non-destructive testing, some machined surfaces may still exhibit defects such as pores and inclusions that do not meet product requirements. These defects must be cleaned and welded, then re-machined or polished to ensure that the surface meets the product's requirements for dimensional accuracy, flatness, and surface roughness.

[0003] In actual production, when encountering the aforementioned planar defects, the priority is grinding after welding to meet the requirements, given the significant time and labor costs associated with re-machining, such as the extensive clamping and positioning, production waiting time, and product transportation. However, when the dimensional accuracy and flatness requirements for the surface are high, the grinding tool itself has a high vibration frequency and lacks effective fixed support. Therefore, re-machining is the only option, which prolongs the production cycle, increases production costs, and easily leads to waste of resources.

[0004] Therefore, in order to solve the problem that during the plane grinding process, the grinding tool itself is unstable and cannot meet the plane processing requirements, it is now necessary to provide a machined plane grinding auxiliary device. Utility Model Content

[0009] This solution is aimed at metal products with high dimensional accuracy and flatness, and designs a machined surface grinding auxiliary device. The main structure is installed on the neck of the mold and fixed through a locking structure. At the same time, the extended length of the positioning rod in the positioning assembly is adjusted to ensure the height positioning on the grinding surface, thereby ensuring that the abrasive is always in the same stable plane during the grinding process, reducing the offset caused by the shaking of the mold itself, and ensuring that the grinding is always in a measurable and controllable stable state to meet the needs of high-precision and high-flatness grinding, thereby saving the need for complex machining links, shortening the production cycle, reducing production costs, and effectively improving grinding production efficiency.

[0025] The following is further described in detail through specific implementation methods:

[0026] The figure marks in the drawings of the specification include: grinding tool 1, abrasive 2, main structure 3, locking structure 4, positioning plate 5, mounting hole 6, notched end 7, arc-shaped end 8, adjustment groove 9, positioning assembly 10, positioning rod 11, sliding foot 12, height adjustment section 13, sliding section 14, ball 15, adjustment block 16, locking block 17, annular hoop 18, connecting rod 19, positioning plane 20.

[0027] Example 1

[0028] This embodiment is basically as shown in the attached Figure 1 The figure shows a device for assisting machined surface grinding, comprising a grinding tool 1 connected to a power input at one end, and an abrasive 2 mounted at the lower end of the neck of the grinding tool 1. During grinding, the bottom of the abrasive 2 contacts the surface of the workpiece to be ground. In this embodiment, the device comprises a main structure 3 integrally mounted on the neck of the grinding tool 1, and an abrasive 2 mounted on the grinding tool 1 for grinding is disposed at the lower end of the main structure 3. In this embodiment, the overall diameter of the main structure 3 is greater than the diameter of the abrasive 2, so that the outer side of the main structure 3 can correspond to the outer position of the abrasive 2, so that the outer side of the main structure 3 can correspond to the upper side of the positioning plane 20.

[0029] As attached Figure 2 As shown, the main structure 3 includes a positioning plate 5 with an overall arc-shaped structure. A mounting hole 6 is provided in the center of the positioning plate 5 for the neck of the mold 1 to pass through, so that the positioning plate 5 is sleeved on the mold 1. In this embodiment, the positioning plate 5 includes a notch end 7 and an arc-shaped end 8. In this embodiment, the notch end 7 is a planar structure. When grinding, the notch end 7 is oriented toward the plane to be grinded to prevent the boss structure on the grinding plane from blocking the positioning plate 5, making it impossible to grind the boss corners. An adjustment groove 9 is provided on the periphery of the positioning plate 5 along the periphery of the positioning plate 5, that is, the adjustment groove 9 is provided on one side of the arc-shaped end 8 and is arranged around the arc-shaped end 8.

[0030] A plurality of positioning components 10 are movably mounted on the adjustment slot 9. In this embodiment, the number of positioning components 10 is not less than 3 to ensure stability and flatness. The specific number can be adjusted to 4, 5 or 6 according to actual needs, and there is no restriction here.

[0031] Combined with attachment Figure 3As shown, the positioning assembly 10 includes a positioning rod 11 inserted into the adjustment slot 9. A sliding foot 12 is provided at the lower end of the positioning rod 11, which contacts a positioning surface 20 on the workpiece surface. In this embodiment, the positioning rod 11 includes a height adjustment section 13 and a sliding foot 12, with the sliding foot 12 positioned below the height adjustment section 13. Specifically, the sliding foot 12 includes a sliding section 14. In this embodiment, the sliding section 14 and the height adjustment section 13 are integrally formed. A ball 15 is mounted at the bottom of the sliding section 14 for sliding. Specifically, a spherical groove is defined at the bottom of the sliding section 14, with a diameter that matches the diameter of the ball 15 and a volume slightly larger than the hemisphere of the ball 15. This allows the ball 15 to be directly locked into the spherical groove by pressing it into the groove, allowing the ball 15 to roll in all directions within the groove without damaging the workpiece surface. Using a handheld grinding tool, the entire assembly, including the grinding tool, abrasive, and device, is pressed against the positioning surface 20, facing the grinding direction. Grinding is completed when the abrasive contacts a protrusion such as a weld scar.

[0032] An adjustment block 16 is mounted on the upper end of the positioning rod 11 to assist in adjusting the length of the positioning rod 11 extending beyond the positioning plate 5. The adjustment block 16 is mounted within the adjustment slot 9 and is connected to the height adjustment section 13. In this embodiment, the adjustment block 16 is an inverted T-shaped structure, allowing the upper end of the adjustment block 16 to be retained within the adjustment slot 9. The internal threads of the adjustment block 16 limit the vertical movement of the height adjustment section 13. A locking block 17 is sleeved on the upper portion of the adjustment block 16. During installation, the locking block 17 is connected to the upper portion of the adjustment slot 9. In this embodiment, the locking block 17 is a locking nut. The positioning rod 11 is threadedly connected to the internal threads of the adjustment block 16. With the adjustment block 16 connected, the positioning rod 11 can adjust its extension length by rotating itself, thereby achieving height adjustment. The external thread of the adjusting block 16 is locked to the positioning plate 5 through a threaded connection with the locking block 17. The height of the positioning plate 5 from the plane is adjusted by rotating the positioning rod 11 itself. At the same time, in this embodiment, the inscribed circle diameter of the locking block 17 is larger than the width of the adjusting groove 9. The adjusted position of the positioning rod 11 is locked by the locking block 17 to ensure flatness and stability during the grinding process.

[0033] As attached Figure 2 As shown, a locking structure 4 is installed above the main structure 3 to enable the main structure 3 to be sleeved on the neck of the mold 1. Figure 4 As shown, the locking structure 4 is disposed above the main structure 3 and includes two oppositely disposed annular hoops 18, which are fastened to the neck of the mold 1 via fastening bolts. Connecting rods 19 are integrally formed at the lower ends of the annular hoops 18 on one side, connecting the locking structure 4 to the positioning plate 5 via the connecting rods 19, thereby securing the main structure 3 to the locking structure 4.

[0034] The specific implementation process is as follows:

[0035] As attached Figure 1To the attached Figure 4 As shown, first, the main structure 3 is installed on the neck of the grinding tool 1 through the locking structure 4, and the abrasive 2 is installed under the grinding tool 1 so that the abrasive 2 is located below the main structure 3. Then, multiple positioning components 10 are installed in the adjustment groove 9. When the surface to be ground and the positioning plane 20 are on the same plane, the positioning rods 11 are first screwed in and out of the adjustment block 16 to adjust the height of each positioning rod 11, thereby adjusting the position of the bottom of each ball 15, so that each ball 15 is higher than the bottom of the abrasive 2, and then the bottom of the abrasive 2 is in contact with a machined surface or a scribing platform with good flatness. Then, the positioning rods 11 are screwed in and out of the adjustment block 16 to adjust the height of each positioning rod 11, so that each ball 15 is in contact with a machined surface or a scribing platform with good flatness, and the plane where the bottom of the positioning component 10 is located is adjusted to the same plane as the bottom of the abrasive 2.

[0036] Turn on the power input of the grinding tool 1, make the abrasive 2 and the ball 15 of the sliding foot 12 contact with the qualified plane near the plane to be polished, that is, the positioning plane 20, and make the notch end 7 of the main structure 3 face the direction of the plane to be polished, while keeping the abrasive 2 and the ball 15 of the sliding foot 12 with a certain pressure on the plane, slide toward the plane to be polished to perform the grinding operation.

[0037] After repeating the grinding process 4-5 times, check the flatness and roughness of the grinding position. If the flatness inspection fails, it is necessary to readjust the position or extension length of the sliding foot 12 and perform the grinding operation again; if the roughness fails, it is necessary to replace the abrasive or the abrasive type (such as changing the grinding wheel to a flapper blade), and re-grind after debugging until the inspection is qualified.

[0038] In this embodiment, the height positioning on the grinding plane is ensured by adjusting the extension length of each sliding foot 12 in the positioning assembly, thereby ensuring that the abrasive is always in the same stable plane during the grinding process, reducing the offset caused by the shaking of the grinding tool itself, and ensuring that the grinding is always in a measurable and controllable stable state to meet the requirements of high-precision and high-flatness grinding, thereby saving the need for complex machining links, shortening the production cycle, reducing production costs, and effectively improving grinding production efficiency.

[0039] Example 2

[0040] In this embodiment, the number of positioning components 10 can be dynamically adjusted according to the specific conditions of the surface to be polished and the positioning surface 20, as shown in the attached figure. Figure 5As shown, since the positioning plane 20 has a small applicable area and is wide on both sides, four positioning assemblies 10 can be provided to ensure the stability and smoothness of the mold 1. The positions of the positioning assemblies 10 in the adjustment slots 9 are then adjusted so that all positioning assemblies 10 are placed on the positioning plane 20 and distributed on both sides of the wider positioning plane 20. This ensures the relative flatness of the sliding feet 12 and the stability of the main structure 3. This also makes it suitable for grinding irregular surfaces and improves versatility.

[0041] Example 3

[0042] In this embodiment, when the area of ​​the plane to be polished is small and there is a positioning plane 20 around it that is lower than and parallel to the plane to be polished, that is, the plane to be polished and the positioning plane 20 are in a stepped structure, as shown in the attached figure. Figure 6 As shown, first adjust the bottom of the abrasive to be flush with the surface to be polished. Then, select the number of positioning assemblies 10 based on the positioning plane 20, for example, set to five. Adjust the position of the positioning assembly 10 within the adjustment slot 9 and adjust the extension length of each sliding foot 12 in the positioning assembly 10 so that each sliding foot 12 is on the positioning plane 20. This determines the smoothness and stability of the polishing process. This makes it suitable for polishing surfaces of various sizes, providing greater flexibility and versatility.
