Description

Technical Field

[0001] This invention relates to the field of hydraulic valve block machining, and in particular to a multi-station hydraulic valve block machining system. Background Technology

[0002] Hydraulic valve blocks are key integrated components in hydraulic systems. They are typically made of high-strength metal through precision machining. Their interiors are formed by drilling, milling, and other processes to create an interconnected network of channels. Externally, they have multiple standardized mounting interfaces and pressure ports. This component integrates dispersed hydraulic valves, pipe fittings, and auxiliary components onto a single block to achieve the logical control and distribution functions of the hydraulic circuit.

[0003] In the traditional machining process of hydraulic valve blocks, ordinary machining centers or vertical machine tools are usually used for surface-by-surface machining. The workpiece needs to be manually clamped, positioned and rotated multiple times. This is not only cumbersome and inefficient, but also has large repeated positioning errors, which affect the positional accuracy of the hole system and the quality of the sealing surface. Especially in multi-variety, small-batch production, frequent changes of fixtures and adjustments to the process lead to low equipment utilization and high production costs. Although existing technologies have multi-station turntable designs, most lack the linkage mechanism for automatic workpiece orientation switching and reliable locking during machining, making it difficult to achieve continuous machining of multiple surfaces and multiple hole systems of hydraulic valve blocks in a single clamping.

[0017] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Example

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a multi-station hydraulic valve block processing system includes a frame 1, a processing mechanism 2 is provided inside the frame 1, and a rotary locking mechanism 3 is provided on the processing mechanism 2; The processing mechanism 2 includes a drive motor 201. The output shaft of the drive motor 201 is detachably connected to a turntable 202. An electric slide rail 203 is installed inside the turntable 202. An electric slider 204 is slidably connected to the inner side of the electric slide rail 203. A rotating shaft 205 is rotatably connected to the top of the electric slider 204. A dual-axis servo motor 206 is fixedly connected to the top of the rotating shaft 205. A soft pad 207 is fixedly connected to the top of the dual-axis servo motor 206. A rotating seat 208 is installed on the top of the soft pad 207. A hydraulic clamp 209 is installed on the top of the rotating seat 208.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a controller is installed on the frame 1. The controller is connected to the drive motor 201, the dual-axis servo motor 206, the electric slide rail 203 and the electric slider 204 respectively. The rotating seat 208 is located above the turntable 202. There are no fewer than three rotating seats 208 and they are centrally symmetrically distributed.

[0020] By setting a controller on the frame 1 and connecting it with components such as the drive motor 201 and the dual-axis servo motor 206, centralized control and automated coordination of the multi-station machining system are realized, improving the controllability and ease of operation of the machining process. At the same time, at least three rotating seats 208 are centrally symmetrically distributed above the turntable 202, ensuring the balance of multiple workpiece loads and the uniform distribution of machining stations, which helps to improve the stability of system operation and machining efficiency.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the drive motor 201 is fixedly connected inside the frame 1. The bottom of the turntable 202 is smooth and fits against the inner bottom wall of the frame 1. A protective shell is fixedly connected to the top of the rotating shaft 205. The dual-axis servo motor 206 is fixedly connected inside the protective shell. The output shaft of the dual-axis servo motor 206 extends to the outside of the protective shell and connects to the bottom of the rotating seat 208. The soft pad 207 is elastic. There are two hydraulic clamps 209, which are symmetrically distributed on the top surface of the rotating seat 208. The inner top wall of the frame 1 is provided with cutting tools symmetrically distributed on both sides of the hydraulic clamps 209.

[0022] By fixing the drive motor 201 inside the frame 1 and smoothly fitting the bottom of the turntable 202 against the inner bottom wall of the frame 1, the stability and structural rigidity of the turntable 202 during rotation are enhanced. The dual-axis servo motor 206 is placed inside the protective shell and its output shaft is connected to the rotating seat 208. With the help of the elastic soft pad 207, the dual-axis servo motor 206 is protected and can provide support when the rotating seat 208 rotates. The two hydraulic clamps 209 are symmetrically distributed to achieve dual-station clamping of the workpiece. With the help of the symmetrically arranged cutting tools on the inner top wall of the frame 1, the synchronous or alternating processing of multiple sides of the workpiece is realized.

[0023] like Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the rotary locking mechanism 3 includes a gear 301, a rack plate 302 fixedly connected inside the turntable 202, a chamber 303 opened inside the turntable 202, a sliding plate 304 slidably connected inside the chamber 303, a plug rod 305 fixedly connected to the side of the sliding plate 304 near the gear 301, a spring 306 fixedly connected between the sliding plate 304 and the inner wall of the chamber 303, a first adjusting rod 307 fixedly connected to the side of the sliding plate 304 away from the plug rod 305, a second adjusting rod 308 slidably connected inside the chamber 303, a movable frame 309 rotatably connected inside the chamber 303, and limit blocks 310 fixedly connected to the outer sides of both the first adjusting rod 307 and the second adjusting rod 308.

[0024] The rotary locking mechanism 3 is driven by the meshing of gear 301 and rack plate 302. In conjunction with the sliding plate 304 in the chamber 303, it drives the insertion rod 305 to engage with the rotating shaft 205, thereby achieving automatic locking of the rotating seat 208. The linkage design of the first adjusting rod 307, the second adjusting rod 308, the movable frame 309, and the limiting block 310 allows the insertion action of the insertion rod 305 to be triggered when the rotating shaft 205 moves with the electric slider 204 to the side of the electric slide rail 203 away from the drive motor 201. This achieves mechanical locking of the rotating seat 208 at a specific work position, preventing the hydraulic valve block on the top surface of the rotating seat 208 from rotating unexpectedly during the processing.

[0025] Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, gear 301 is fixedly connected to the outside of rotating shaft 205, rack plate 302 is located above electric slider 204 and meshes with gear 301, and the teeth on rack plate 302 are distributed on the side near chamber 303.

[0026] By fixing the gear 301 to the outside of the rotating shaft 205 and meshing it with the rack plate 302 on one side, the gear 301 rolls along the rack plate 302 and drives the rotating shaft 205 to rotate synchronously when the rotating shaft 205 moves along the electric slide rail 203. This achieves the linkage between the sliding and rotation of the rotating seat 208, improving the accuracy and efficiency of workstation switching.

[0027] Figure 3 , Figure 5 and Figure 6 As shown, the chamber 303 and the rotating seat 208 are arranged in a one-to-one correspondence, and the chamber 303 is located on the side of the electric slide rail 203 away from the drive motor 201.

[0028] By providing a corresponding chamber 303 for each rotating seat 208 and arranging the chamber 303 on the side of the electric slide rail 203 away from the drive motor 201, when the electric slider 204 drives the rotating seat 208 to move towards the chamber 303, it can rotate under the action of the gear 301 and the rack plate 302, thereby exchanging the two workpieces on the top surface of the rotating seat 208 and improving the processing efficiency of the hydraulic valve block.

[0029] like Figure 3 , Figure 5 and Figure 6 As shown, a first guide rod is fixedly connected to the top of the sliding plate 304, and a first guide groove adapted to the moving trajectory of the first guide rod is opened inside the turntable 202. The first guide rod is connected to the inner top wall of the chamber 303.

[0030] By setting a first guide rod on the top of the sliding plate 304 and opening a first guide groove in the turntable 202 to cooperate with it, the movement path of the sliding plate 304 can be precisely guided and limited, avoiding the insertion rod 305 from deflecting during the operation, ensuring that the insertion rod 305 can be accurately inserted into the slot of the rotating shaft 205, and improving the accuracy and reliability of mechanical locking.

[0031] like Figure 3 , Figure 5 and Figure 6 As shown, a second guide rod is fixedly connected to the bottom of the second adjusting rod 308, and a second guide groove adapted to the movement trajectory of the second guide rod is opened inside the turntable 202. The second guide groove is connected to the inner bottom wall of the chamber 303.

[0032] By setting a second guide rod at the bottom of the second adjusting rod 308 and cooperating with the second guide groove, the movement of the second adjusting rod 308 is guided, so that its contact position with the electric slider 204 remains stable. This ensures that the second adjusting rod 308 can be reliably pushed when the electric slider 204 moves, thereby triggering the locking action through the movable frame 309, thus improving the accuracy of the mechanism linkage.

[0033] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the movable frame 309 is rotatably connected to the inside of the chamber 303 via a rotating rod. Both sides of the movable frame 309 are provided with clearance holes that are adapted to the moving trajectory of the limiting block 310. The front side of the limiting block 310 is fixedly connected with a stop block with a diameter larger than the diameter of the clearance hole. The stop block is in contact with the surface of the movable frame 309. The outer side of the rotating shaft 205 is provided with a slot that is adapted to the insertion rod 305. The second adjusting rod 308 passes through the electric slide rail 203 and is in contact with the electric slider 204.

[0034] The movable frame 309 is rotatably mounted in the chamber 303 via a rotating rod, and has a clearance hole that cooperates with the limiting block 310. The limiting block 310 is prevented from dislodging by a stop block, so that the movement of the first adjusting rod 307 and the second adjusting rod 308 can drive the movable frame 309 to swing, thereby controlling the insertion and removal of the insertion rod 305. At the same time, the second adjusting rod 308 passes through the electric slide rail 203 and fits against the electric slider 204, converting the movement of the electric slider 204 into a locking trigger signal, realizing the mechanical linkage between the position of the electric slider 204 and the locked state of the rotating seat 208, with a direct response.

[0035] In operation, the operator first accurately clamps the hydraulic valve block workpiece to be processed onto the two symmetrically arranged hydraulic clamps 209 on the top of the rotating seat 208, ensuring the workpiece remains stable during subsequent processing. Then, the system starts, and the drive motor 201 begins to run, driving the turntable 202 to rotate inside the frame 1. Because the bottom of the turntable 202 has a smooth design and fits snugly against the inner bottom wall of the frame 1, the rotation process is stable. The rotation of the turntable 202 moves the rotating seat 208 to the processing area below the cutting tool on the top wall of the frame 1. Once the rotating seat 208 enters the processing area, the electric slide rail 203 installed inside the turntable 202 starts, driving the electric... The slider 204 slides laterally in the horizontal direction. During the sliding process, the gear 301 fixedly connected to the outside of the rotating shaft 205 meshes with the rack plate 302, and the gear 301 rolls along the rack plate 302, thereby driving the rotating shaft 205 to rotate synchronously. This enables the rotation of the rotating seat 208 and the workpiece on it to switch positions, so that the surface to be processed is aligned with the tool. When the electric slider 204 slides to the far end of the electric slide rail 203, its side contacts the second adjusting rod 308 passing through the electric slide rail 203 and pushes it to move into the cavity 303. The second guide rod at the bottom of the second adjusting rod 308 moves along the second guide groove, and the limiting block 310 fixedly connected to the outside of the second adjusting rod 308 moves accordingly. The movement of the movable frame 309 inside the chamber 303 causes it to swing. The movable frame 309 has a clearance hole that matches the movement trajectory of the limiting block 310, and the limiting block 310 has a stop block with a diameter larger than the clearance hole on its front side, preventing it from dislodging when the movable frame 309 is pushed. The swinging of the movable frame 309 further pushes the first adjusting rod 307 and the sliding plate 304 to slide within the chamber 303 and compress the spring 306. Simultaneously, it drives the insertion rod 305 to move out of the chamber 303, ultimately accurately inserting it into the corresponding slot on the outside of the rotating shaft 205, completing the mechanical locking of the rotating seat 208 in the processing position. This effectively prevents accidental rotation of the workpiece during processing. After locking is complete, the frame... The cutting tools symmetrically arranged on both sides of the hydraulic fixture 209 on the inner top wall begin to perform multi-face machining on the workpiece. If it is necessary to machine stepped holes or inclined structures, the dual-axis servo motor 206 can be started. Its output shaft drives the rotating seat 208 to tilt around the connection point. The soft pad 207 provides buffering and adaptive support due to its elasticity, so that the workpiece is at the required angle to adapt to the cutting tool machining path. After the machining is completed, the electric slider 204 slides in the opposite direction along the electric slide rail 203. The electric slider 204 disengages from the second adjusting rod 308. The compressed spring 306 releases its elastic force, pushes the sliding plate 304 to reset, and drives the insertion rod 305 to exit from the slot of the rotating shaft 205. The locking state of the rotating seat 208 is released.Simultaneously, under the transmission action of the first adjusting rod 307 and the movable frame 309, the second adjusting rod 308, guided by its bottom second guide rod, also resets to its initial position. Finally, the drive motor 201 drives the turntable 202 to rotate again, moving the processed workpiece out and sending it into the next rotating seat 208 to be processed. The system cycles in this manner, realizing a continuous and efficient automated processing flow for multiple stations and multiple workpieces, significantly improving the production efficiency of hydraulic valve block processing.
