Description

Technical Field

[0001] This utility model relates to the field of engine cylinder block surface processing, specifically an engine surface strengthening treatment device. Background Technology

[0002] Modern engine blocks typically integrate the crankcase and cylinder block into a single assembly, which usually also includes components such as coolant passages and oil passages. Currently, existing surface grinding devices are usually single-unit grinding structures, leading to cumbersome and inconvenient disassembly and replacement of different grinding structures to meet varying grinding precision requirements, resulting in low surface processing efficiency. Therefore, this paper proposes an engine surface strengthening treatment device to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide an engine surface strengthening treatment device in order to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: an engine surface strengthening treatment device, comprising a drive shaft and a grinding disc, a first grinding ring block, and a second grinding ring block distributed from the inside out. The bottom end of the drive shaft is fixedly installed at the middle position of the cross-welding part between two Z-shaped plates. Each Z-shaped plate has a circular hole on both sides of its end walls from the inside out, and the bottom of the middle position of the cross-welding part between the two Z-shaped plates is fixedly connected to the middle part of the grinding disc through a connecting shaft. A set of triangular blocks is installed at the top of a set of connecting rods on one side of the first grinding ring block, and another set of triangular blocks is installed at the top of another set of connecting rods on one side of the second grinding ring block. A hydraulic cylinder is installed at the top of each set of triangular blocks, and the cylinder body is fixedly connected to the corresponding part of the inner wall of the outer cover through a connecting piece.

[0005] Preferably, the middle position of the top end face of the outer cover is fixedly connected to the corresponding part of the drive shaft, and the surface of the outer cover is provided with a control window.

[0006] Preferably, the two side walls at both ends of the zigzag plate are provided with two sets of circular holes from the inside out, and the interior of each set of circular holes is in sliding contact with the surface of the connecting rod.

[0007] Preferably, a bearing housing is mounted on the drive shaft, and a connecting block is mounted on one side of the bearing housing.

[0008] Preferably, two guide holes are symmetrically opened at one end of the connecting block, and a guide rod is slidably installed in each guide hole.

[0009] Preferably, the drive shaft is connected to an external drive device via a coupling.

[0010] Compared with the prior art, the advantages of this utility model are as follows: By using two sets of hydraulic cylinders distributed from the inside out to push and pull the first and second grinding ring blocks respectively, and combined with the grinding disc located in the middle, the grinding precision of the grinding disc, the first grinding ring block and the second grinding ring block gradually increases from the inside out, which can form a multi-stage grinding structure; the extension and retraction state of the hydraulic cylinders can be adjusted through the operating window located on the outer cover, which is conducive to adjusting the grinding structure with the required grinding precision to contact the corresponding surface of the engine cylinder block, solving the problem of overly cumbersome disassembly and replacement of the grinding structure, and improving grinding efficiency.

[0019] Please see Figure 1-3 As shown, an engine surface strengthening treatment device includes a drive shaft 1 and a grinding disc 2, a first grinding ring block 3, and a second grinding ring block 4 distributed from the inside out. The bottom end of the drive shaft 1 is fixedly installed at the middle position of the cross-welding part between two Z-shaped plates 8. Each Z-shaped plate 8 has a circular hole 810 opened from the inside out on both side walls at both ends. The bottom of the middle position of the cross-welding part between the two Z-shaped plates 8 is fixedly connected to the middle part of the grinding disc 2 through a connecting shaft 210. A set of triangular blocks 10 is installed at the top of a set of connecting rods 9 on one side of the first grinding ring block 3. Another set of triangular blocks 10 is installed at the top of another set of connecting rods 9 on one side of the second grinding ring block 4. A hydraulic cylinder 11 is installed at the top of each set of triangular blocks 10, and the cylinder body of the hydraulic cylinder 11 is fixedly connected to the corresponding part of the inner wall of the outer cover 5 through a connecting piece 12.
