Description

Technical Field

[0001] The utility model relates to the field of oil cylinder processing tooling, in particular to a novel oil cylinder precision internal grinding tooling. Background Art

[0002] In the field of mechanical processing, especially when machining the internal bores of precision components like cylinder blocks, ensuring high precision and surface quality is crucial. To achieve precise machining of cylinder bores, a common method is to clamp the outer diameter of the cylinder block using a three-jaw chuck on a grinding machine, thereby ensuring secure clamping of the cylinder block. Subsequently, the machine's spindle rotates, driving the clamped cylinder block in synchronous rotation, while the grinding tool performs precision grinding of the internal bore. This method has gained widespread adoption within the industry due to its high efficiency and high machining accuracy.

[0003] However, with the continuous advancement of industrial technology and increasing demands for product quality, the problems exposed by traditional machining methods are becoming increasingly prominent. Although three-jaw chucks provide relatively stable clamping, uneven or excessive clamping force can easily squeeze local areas of the cylinder body when clamping the outer diameter of the cylinder body, resulting in pinching or deformation. This pinching and deformation not only affects the appearance of the cylinder body but, more importantly, directly reduces the accuracy of the internal bore machining and can even lead to serious problems such as oil leakage and poor sealing during subsequent assembly or use.

[0035] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The embodiment of the present application provides a new type of precision internal grinding tool for a cylinder, which can solve the problem in the prior art that a local area of the cylinder body is easily pinched or deformed during the clamping process of a three-jaw chuck.

[0037] Reference Figure 1 The present application discloses a new type of oil cylinder precision internal grinding tooling, including a mounting disc 1, a receiving tray 2 and a clamping and fixing block 3. The mounting disc 1 is provided with a plurality of mounting threaded holes 11, so that the operator can insert a plurality of mounting bolts into the mounting threaded holes 11 to fix the mounting disc 1 to the grinding machine station; the receiving tray 2 is arranged on the mounting disc 1, and the receiving tray 2 is provided with a receiving station, which is specifically provided with a semi-cylindrical arc groove, so that when receiving the workpiece 4 to be processed, the contact between the receiving plate and the workpiece 4 to be processed is smoother, thereby reducing the extrusion of the surface of the workpiece 4 to be processed; a clamping station is provided on the clamping and fixing block 3, and the clamping and fixing block 3 is detachably provided on the receiving tray 2, and the clamping station and the receiving station are spliced to form a workpiece clamping station, and the clamping station is also provided with a semi-cylindrical arc groove to protect the upper surface of the workpiece 4 to be processed.

[0038] When performing the internal grinding operation on the workpiece 4 to be processed, after installing the mounting disc 1 on the grinding machine station, the operator places the workpiece 4 to be processed on the receiving station of the receiving tray 2, and then fixes the pressing and fixing block 3 on the receiving tray 2 so that the pressing station and the receiving station cooperate with each other to clamp the workpiece 4 to be processed, thereby driving the workpiece 4 to be processed to perform subsequent internal grinding processes. The installation steps are simple and can protect the surface of the workpiece 4 to be processed, solving the problem in the prior art that the local area of the cylinder block is prone to being clamped or deformed during the clamping process of the three-jaw chuck.

[0039] More specifically, three installation threaded holes 11 are specifically provided. The three installation threaded holes 11 are symmetrically distributed on the edge of the mounting disc 1 with the center of the mounting disc 1 as the axis, so that the installation of the mounting disc 1 is more stable. In the initial design, the installation holes can be opened according to the installation requirements of the grinding machine station, and then the mounting disc 1 can be quickly installed through the installation bolts, which is more convenient to use; the mounting disc 1 and the receiving tray 2 are integrally formed, thereby enhancing the connection strength between the mounting disc 1 and the receiving tray 2; the pressing and fixing block 3 is fixed on the receiving tray 2 through the connection bolt 31. A plurality of bolt holes are provided on the pressing and fixing block 3, and corresponding connection holes are also provided on the end of the receiving tray 2 away from the mounting disc 1 corresponding to the bolt holes on the pressing and fixing block 3. The connection bolt 31 is threadedly connected to the bolt hole and the connection hole at the same time to stably install the pressing and fixing block 3 on the receiving tray 2.

[0040] When performing the internal grinding operation on the workpiece, since different types of workpieces have different shapes, considering that there are special-shaped protrusions at the ends of some workpieces, a workpiece reserved hole 12 is coaxially provided on the mounting disc 1 for the special-shaped protrusion of the workpiece 4 to be processed to pass through, which is convenient for placing the workpiece 4 to be processed and can further limit and fix the workpiece 4 to be processed. After the workpiece 4 to be processed is placed on the mounting disc 1, the special-shaped protrusion passes through the reserved hole 12 and acts together with the pressing and fixing block 3 to form a stable and reliable fixing system for the workpiece 4 to be processed. This system can not only effectively prevent the workpiece 4 to be processed from moving or deflecting during the processing, but also improve the processing accuracy and reduce the processing error caused by the position change of the workpiece.

[0041] In addition, the design of the workpiece reserved hole 12 also fully considers the convenience and flexibility during the processing. When it is necessary to replace or adjust the workpiece 4 to be processed, the operator can easily take out or put in the workpiece 4 to be processed through the reserved hole 12 without a complex disassembly process, thereby improving the processing efficiency and reducing the potential damage to the workpiece 4 to be processed and the mounting disc 1 caused by frequent disassembly.

[0042] After the workpiece 4 to be processed is placed on the receiving tray 2, the end of the mounting disc 1 where the receiving tray 2 is provided bears a relatively large load. In order to maintain the force balance of the mounting disc 1 during the subsequent internal grinding process, a number of counterweight holes 13 are also provided at the end of the mounting disc 1 away from the receiving tray 2, and a counterweight bar with a suitable size is equipped in each counterweight hole 13. More specifically, as a key component to achieve balance, the material selection of the counterweight bar is also important. Specifically, a metal material with high density, corrosion resistance and easy adjustment can be selected to make the counterweight bar, such as materials with high strength like stainless steel and iron, so that it can provide enough weight to balance the load of the workpiece 4 to be processed at the other end when needed, and will not add unnecessary burden to the mounting disc 1 due to its own excessive weight.

[0043] During the actual operation process, the operator can flexibly select and insert different numbers of counterweight bars according to the specific weight of the workpiece 4 to be processed. This process not only reflects the flexibility of the operation, but also requires the operator to have high professional qualities and judgment abilities to improve the accuracy and effectiveness of the counterweight adjustment.

[0044] Through the ingenious combination of the counterweight holes 13 and the counterweight bars, the mounting disc 1 can maintain a stable force balance state during the subsequent internal grinding operation. This not only helps to reduce the processing errors caused by vibration or shaking, but also can extend the service life of the equipment and reduce the maintenance cost. At the same time, this design also improves the safety and efficiency of the operation, providing a strong guarantee for high-precision and high-efficiency machining.

[0045] In order to further improve the service life of each component and enhance the structural strength of the mounting disc 1, the receiving tray 2 and the pressing and fixing block 3, the mounting disc 1, the receiving tray 2 and the pressing and fixing block 3 are all made of high-strength metal materials, such as stainless steel, iron and other materials. This kind of material not only has excellent tensile strength and yield strength to ensure stable operation under high-load working conditions, but also its excellent corrosion resistance can effectively resist the erosion of various harsh environmental factors, such as humidity, acid and alkali, etc., and thus can well improve the service life of the mounting disc 1, the receiving tray 2 and the pressing and fixing block 3 and reduce the subsequent maintenance cost.
