[0022] The surface of the part needs to be repaired after surface damage, generally, the damaged tissue protruding from the surface is removed, then a layer of wear-resistant material is fused on the surface by cladding technology, or a layer of material of the workpiece body is fused, then the fused surface needs to be ground to the preset size, and the inner wall of the workpiece is generally ground by a boring machine, the boring machine comprises a boring shaft 2 connected with a boring tool at one end and connected with a driving device at the other end, a driving device for driving the boring shaft 2 to rotate, and a boring tool mechanism 3 at one end of the boring shaft 2 for deepening into the inside of the part. When the hole depth of the part is large, the length of the boring shaft 2 is generally increased to meet the requirement of hole depth, but when the boring shaft 2 is lengthened, the disturbance in the length direction is increased, and when the boring tool mechanism 3 at one end has a large mass, the disturbance of the boring shaft 2 is also increased, thereby the boring grinding precision is low. Therefore, how to improve the boring grinding precision during boring grinding of the part with deep hole is a problem to be solved in the prior art. Therefore, the utility model provides a boring grinding assembly for the inner wall of a cylinder body, which is compatible with hole machining, inner hole surface machining, workpiece outer surface machining and workpiece machining of various sizes, thereby solving the technical problems in the prior art.

[0023] Specifically, as shown in Figure 1 and Figure 2 The utility model provides a boring grinding assembly for the inner wall of a cylinder body, which comprises a driving unit 1, a boring shaft 2 and a boring tool mechanism 3. The driving unit 1 is connected with one end of the boring shaft 2, the shaft body of the boring shaft 2 is provided with a connecting block 21, and the boring tool mechanism 3 is connected with the connecting block 21. The boring tool mechanism 3 is provided with a tool holder 31 parallel to the boring shaft 2, and a boring tool is clamped with the tool holder 31. The driving unit 1 comprises a support plate 11, a movable plate 12, a connecting plate 13 and a base 14. The base 14 comprises a plurality of sliding plates which are sleeved with each other. The support plate 11 is connected with the sliding plates, the first surface of the connecting plate 13 is slidably connected with the movable plate 12, the second surface of the connecting plate 13 is connected with the support plate 11, and a driving device is arranged on the movable plate 12 and used for connecting with the boring shaft 2.

[0024] As described previously, the utility model provides a kind of for the boring and facing of cylinder inner wall component, drive unit 1 drives boring shaft 2 rotation, so that boring cutter mechanism 3 on boring shaft 2 rotates, utilizes boring cutter to boring and facing processing to complete the repair of cylinder inner wall.Cylinder is approached to drive unit 1 on the sliding plate of multiple sleeve connections, so that drive unit 1 can be close, so that boring shaft 2 moves cylinder hole depth;In addition, boring shaft 2 includes multiple connecting blocks 21 fixedly connected with boring cutter mechanism 3, not only can operating personnel move the position of boring cutter mechanism 3 according to the hole depth of cylinder, to be compatible with the boring and facing of cylinder at different hole depth position, and, connecting block 21 can dynamically balance the disturbance of boring shaft 2, reduce the axial deviation of boring shaft 2, to further improve the precision of cylinder internal control boring and facing.In addition, the sliding plate of drive unit 1 makes the driving device can be adjusted in the direction perpendicular to boring shaft 2, to satisfy the inner wall processing of different aperture cylinder, to further improve the compatibility of the component to different aperture parts processing.

[0025] As shown in Figure 3 And Figure 4 The foregoing boring cutter mechanism 3 further includes: front mounting plate 32, rear mounting plate 33, the tool rest 31 includes limit hole, the limit hole is connected with the limit column 5 on the boring shaft 2;The front mounting plate 32, the rear mounting plate 33 are connected with the connecting block 21 respectively.The limit column 5 includes two tapered first limiting portion and second limiting portion, the first limiting portion is connected with the boring shaft 2, and the second limiting portion is connected with the limit hole of the tool rest 31.

[0026] It should be noted that the foregoing multiple connecting blocks 21 are independently arranged, i.e. the connecting blocks 21 are uniformly distributed in the axial direction of the boring shaft 2, so that the connecting blocks 21 can dynamically balance the disturbance of the boring shaft 2, reduce the axial deviation of the boring shaft 2, and further improve the precision of the internal control boring and facing of the cylinder.

[0028] Specifically, one end of the limiting column 5 is connected with the boring shaft 2, and the other end is connected with the front mounting plate 32 and the rear mounting plate 33. Because the limiting column 5 is a tapered structure, the distance between the tool holder 31 on the front mounting plate 32 and the rear mounting plate 33 and the inner wall of the cylinder body can be adjusted, thereby meeting the machining of the inner wall of the cylinder body of different sizes without replacing the boring tool mechanism 3, and the practicability of the assembly is improved.

[0031] In some embodiments, the boring tool mechanism 3 further comprises a milling cutter seat connected with the rear mounting plate 33 and used for connecting with a milling cutter. The milling cutter seat is used for arranging the milling cutter, so that the boring shaft 2 can mill the material on the inner surface of the cylinder body, thereby improving the practicability of the assembly. For example, when a sealing groove is machined on the inner surface of the cylinder body to install a sealing ring, a part of the material needs to be milled according to the size of the sealing ring to obtain the sealing groove. It should be noted that the milling cutter seat and the milling cutter in the embodiment are not limited, and the existing milling cutter structure can be referred to, and the milling cutter can be arranged according to the actual machining requirements of the workpiece.

In addition, the arrangement of the connecting block 21 on the boring shaft 2 not only reduces the axial disturbance of the boring shaft 2, but also realizes the honing of the cylinder body at different hole depth positions by arranging the boring tool mechanism 3 on the connecting block 21 at different positions of the boring shaft 2, that is, the boring shaft 2 is compatible with different hole depths, thereby improving the stability of the boring shaft 2 and the honing precision.
