Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing process equipment, and specifically relates to a dual-position, three-process integrated hydraulic clamp for an electromagnetic valve body. Background Technology

[0002] Solenoid valve bodies are widely used and produced in large quantities. They are multi-faceted machined parts with numerous processing steps and high precision requirements. Previously, the machining fixtures were mainly manually clamped, and one fixture was used for each process. To complete the machining, the workpiece needed to be clamped multiple times, which was time-consuming, labor-intensive, occupied too many machine tools and manpower, and the frequent clamping affected the machining accuracy, resulting in low production efficiency and increased production costs. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a simple structure, convenient mounting, and high production efficiency solenoid valve body dual-station three-process integrated hydraulic clamp.

[0004] The technical solution adopted by this utility model to solve the technical problem is: a dual-position, three-process integrated hydraulic clamp for an electromagnetic valve body, including a base plate, a rotatable flange connecting disc rotary actuator, an oil circuit distributor, and a bridge plate. Its characteristic is that the rotatable flange connecting disc rotary actuator is fixedly installed on the upper right side of the base plate, and a tailstock is fixedly installed on the upper left side of the base plate. A rotatable flange connecting disc is connected to the fixed housing of the rotatable flange connecting disc through a bearing. A connecting side plate is fixedly connected to the left side of the rotatable flange connecting disc. The oil circuit of the connecting side plate is connected to the oil circuit of the oil circuit distributor. Oil circuit connectors one and two on the oil circuit distributor are respectively connected to the hydraulic system. A connecting plate is fixedly connected to the left side of the oil circuit distributor, and the connecting plate is fixedly connected to the right end face of the fixed housing. The left side of the connecting side plate is fixedly connected to the right side of the bridge plate, and the left side of the bridge plate is fixedly connected to the right side of the connecting side plate. The oil circuit of the connecting side plate and the bridge plate is connected to the oil circuit of the oil circuit distributor. The left side of connecting side plate two is fixedly connected to the right side of rotatable flange connecting plate two. Rotatable flange connecting plate two is connected to the tailstock via bearings. There is a front station one on the left side of the front of the bridge plate and a front station two on the right side of the front of the bridge plate. There is a support plate on the front of the bridge plate at the middle position between front station one and front station two. Each support plate is equipped with a limit pin and an anti-misalignment guide rod. There is a hydraulic lever cylinder on the left and right sides of each support plate. The top of the hydraulic lever cylinder is equipped with a forked pressure plate. There is a back station one on the left side of the back of the bridge plate and a back station two on the right side of the back of the bridge plate. There is a support plate on the back of the bridge plate at the middle position between back station one and back station two. Each support plate is equipped with a limit pin and an anti-misalignment guide rod. There is a hydraulic lever cylinder on the left and right sides of each support plate on the back of the bridge plate. The top of the hydraulic lever cylinder is equipped with a forked pressure plate. The oil circuit of each hydraulic lever cylinder is connected to the oil circuit of the bridge plate.

[0005] The beneficial effects of this utility model are as follows: The dual-station, three-process integrated hydraulic clamp for the electromagnetic valve body breaks the traditional manual single-process, single-workpiece clamping mode. Through this clamp, hydraulic clamping is performed, allowing simultaneous processing of both the front and back of the bridge plate in dual stations. The forked pressure plate at the top of the hydraulic lever cylinder hydraulically clamps the workpiece via a connecting oil circuit. The rotatable flange connecting disc rotates via a rotary actuator, causing the bridge plate to rotate 360 ​​degrees. When the bridge plate is upright, the surface directly above the workpiece in both front and back dual stations is processed. After rotating 90 degrees, the bridge plate is horizontal, and the surface facing upwards on the front dual station is processed. The bridge plate continues to rotate 90 degrees and stops, returning to an upright position, while simultaneously processing the surface facing upwards on both the front and back dual stations. After rotating another 90 degrees, the bridge plate is horizontal again, and the surface facing upwards on the back dual station is processed. This process completes the processing of all three surfaces of the workpiece in both the front and back dual stations of the bridge plate. It enables the three-sided drilling and milling of workpieces on both the front and back sides to be completed in one setup, saving time and effort. Compared with manual setup, the positioning is more accurate, which not only improves production precision but also greatly increases production efficiency, meeting the needs of mass production.

When the bridge plate 2 is upright, the machining surfaces of the workpiece 17 facing upwards on the front and back of the bridge plate are processed. The bridge plate 2 rotates... After rotating 90 degrees and stopping, the surface of bridge plate 2 is now horizontal. The workpiece-facing surfaces on the front dual-station of bridge plate 2 are then machined. Bridge plate 2 continues to rotate 90 degrees in the same direction and stops, now in an upright position. Simultaneously, the workpiece-facing surfaces on both the front and back dual-stations of bridge plate 2 are machined. The bridge plate rotates another 90 degrees and stops, now horizontal again. The workpiece-facing surfaces on the back dual-station of bridge plate 2 are then machined, thus completing the machining of all three surfaces of the workpiece on both the front and back dual-stations of bridge plate 2. The hydraulic system is then activated, causing the hydraulic lever cylinder 11 to drive the forked pressure plate 10 to release its grip on the workpiece. The machined workpiece 17 is removed from the front and back stations of bridge plate 2, and the next batch of workpieces is placed in for mass production.
