Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic valve cover tooling, and particularly relates to a turning tooling for YA-76S hydraulic valve cover. Background Technique

[0002] The YA-76S hydraulic valve cover is a large quantity of cast aluminum parts, which need precision turning. The machining accuracy needs to be guaranteed. With a large demand, tooling is required for quick clamping and positioning to reduce the standby time of the equipment to meet the production line requirements. The existing jaw clamping has a slow speed, is laborious to operate, and has inaccurate positioning. There is no anti-fooling device, and it is easy to be clamped obliquely or installed reversely, resulting in out-of-tolerance machining dimensions or even scrapping, thus leading to low machining efficiency and unable to meet the production line needs.

[0003] Therefore, it is very necessary to invent a turning tooling for YA-76S hydraulic valve cover. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a turning tooling for YA-76S hydraulic valve cover, which includes a bottom plate, jaws, clamping ring I, anti-fooling notch, hydraulic valve cover, height-limiting column, elastic positioning pin and bushing. The bottom plate is fixedly installed on the tooling base through bolts, and the bottom plate is mutually installed with two mirror-image jaws through guiding chutes; each jaw is fixedly installed with the clamping ring I through bolts, and the anti-fooling notch is arranged on the clamping ring I; the hydraulic valve cover is placed inside the anti-fooling notches arranged by the two clamping rings I, and is in contact with the height-limiting column and elastic positioning pin fixedly installed on the bottom plate, and the bushing is installed on the height-limiting column.

[0005] Preferably, the two jaws installed on the bottom plate are both connected to the hydraulic drive system on the tooling base, and the hydraulic drive system on the tooling base is used to drive the two jaws to move in opposite directions.

[0006] Preferably, the anti-fooling notch arranged on the clamping ring I only allows the hydraulic valve cover to be placed in a specific form, and the two clamping rings I are used to clamp and fix the hydraulic valve cover.

[0007] Preferably, the height-limiting column and the elastic positioning pin are arranged on one side of each other. The height-limiting column is a vertical cylinder, which is used to locate the end face reference of the hydraulic valve cover, and the bushing installed on the height-limiting column is used to support or guide the hydraulic valve cover.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] In the tooling of the present utility model, the height-limiting column and the elastic dowel cooperate with each other to ensure the precise positioning of the hydraulic valve cover during the machining process. The height-limiting column is used to position the end face reference, while the elastic dowel restricts the angular position of the workpiece, effectively preventing offset and rotation during the machining process, thereby improving the machining accuracy. The anti-fooling notch provided on the clamping ring only allows the hydraulic valve cover to be placed in a specific direction, effectively avoiding problems such as out-of-tolerance machining dimensions or even scrapping caused by incorrect clamping (such as clamping in the wrong direction or being crooked). This not only improves the product quality but also reduces the waste of resources caused by rework or scrapping. Since the tooling can quickly and accurately clamp and position the hydraulic valve cover and reduce the downtime caused by incorrect clamping, the machining efficiency is significantly improved. This helps to meet the production requirements of large quantities of cast aluminum parts. Brief Description of the Drawings

[0018] As shown in the attached Figure 1 to the attached Figure 4 figures:

[0019] The YA-76S hydraulic valve cover turning tooling provided by the present utility model includes a base plate 1, clamping jaws 2, a first clamping ring 3, an anti-fooling notch 4, a hydraulic valve cover 5, a height-limiting column 6, an elastic dowel pin 7, and a bushing 8. The base plate 1 is fixedly installed on the tooling base through bolts. The base plate 1 is mutually installed with two mirror-image clamping jaws 2 through guiding chutes. Each clamping jaw 2 is fixedly installed with the first clamping ring 3 through bolts, and the anti-fooling notch 4 is arranged on the first clamping ring 3. The hydraulic valve cover 5 is placed inside the anti-fooling notches 4 arranged on the two first clamping rings 3 and is in contact with the height-limiting column 6 and the elastic dowel pin 7 fixedly installed on the base plate 1. The bushing 8 is installed on the height-limiting column 6.

[0020] Embodiment 1:

[0021] Figure 1 to the attached Figure 3 figures, in this embodiment, the base plate 1 is stably installed on the tooling base, serving as the cornerstone of the entire tooling. The two clamping jaws 2 installed thereon are closely connected to the base plate 1 through precise guiding chutes. These two clamping jaws 2 are directly connected to the hydraulic drive system built into the tooling base, endowing the clamping jaws 2 with fast and powerful driving forces, and enabling the two clamping jaws 2 to move in completely opposite directions easily, thereby realizing the rapid clamping and release of the hydraulic valve cover 5.

[0022] Specifically, the anti-fooling notch 4 on the clamping ring 1 ensures that the hydraulic valve cover 5 is only allowed to be placed in a specific and unique form. This greatly reduces the risk of clamping errors, avoids machining problems caused by incorrect or skewed installation, and improves machining quality and efficiency. At the same time, the two clamping rings 1 work together to provide a stable and reliable clamping force for the hydraulic valve cover 5, ensuring stability during the machining process.

[0023] Specifically, the tooling is also equipped with a combined device of a height-limiting column 6 and an elastic dowel pin 7. The two are arranged on one side of each other, forming a double positioning guarantee for the hydraulic valve cover 5. The height-limiting column 6, in the form of its vertical column, accurately positions the end face reference of the hydraulic valve cover, ensuring the accuracy of the machining depth. The bushing 8 installed on the height-limiting column 6 supports and guides the hydraulic valve cover 5, further improving machining accuracy and efficiency.

[0024] Embodiment 2:

[0025] Appendix Figure 4 As shown, this embodiment is a partial optimization based on Embodiment 1, mainly making adaptive adjustments for the machining requirements of the back surface of the hydraulic valve cover 5. Compared with Embodiment 1, the main change in this embodiment lies in the design of the clamping ring.

[0026] Furthermore, when machining the back surface of the hydraulic valve cover 5 is required, there is no need to replace the entire tooling structure. Only by simple bolt disassembly and installation steps, the original clamping ring 1 can be replaced with the clamping ring 2. The design of the clamping ring 2 fully considers the special requirements of back surface machining. Its thickness is increased compared to the clamping ring 1 to provide a more stable clamping force. At the same time, an anti-fooling notch 4 is also set on the clamping ring 2, but the design of this notch is different from that of the clamping ring 1 in Embodiment 1. It allows the hydraulic valve cover 5 to be placed in the opposite form. This design ensures that whether it is front surface machining or back surface machining, it can be easily achieved by replacing the corresponding clamping ring without large-scale adjustment of the tooling, greatly improving the flexibility and efficiency of machining.

[0027] Working principle

[0028] First, fix the bottom plate 1 on the tooling base with bolts to ensure stability. During operation, open the clamping jaws 2 by stepping on the hydraulic pedal. Place the hydraulic valve cover 5 into the tooling through the anti-fooling notch 4 on the first clamping ring 3. The end face of the hydraulic valve cover 5 is flush with the height-limiting column 6 to position the end face reference. The elastic detent pin 7 is slightly elastically pushed into the hydraulic valve cover 5 by the spring to limit the angular rotation. Drive the clamping jaws 2 and the first clamping ring 3 to clamp the workpiece by stepping on the hydraulic pedal, and then the turning processing can be carried out. After the processing is completed, step on the hydraulic pedal to loosen the hydraulic valve cover 5, take out the processed hydraulic valve cover 5 from the tooling, and perform necessary cleaning and inspection. Repeat the above operations to process the next workpiece. If it is necessary to process the back surface of the hydraulic valve cover 5, replace the second clamping ring 9 according to the method in the second embodiment, and repeat the operations in the clamping stage. Prepare for the processing of the next hydraulic valve cover 5 and repeat the above process.

[0029] Any technical solution that uses the technical solution of the present invention or is designed by those skilled in the art under the inspiration of the technical solution of the present invention to achieve the above technical effects falls within the protection scope of the present invention.
