Description

Technical Field

[0001] The utility model relates to the field of machine tools, in particular to a chuck structure used for a hydraulic valve block machine tool. Background Art

[0002] A hydraulic valve block is a device used to control the flow of liquid in a hydraulic system. It is usually composed of multiple valves that can open or close different channels as needed to control the direction, pressure and flow of the liquid. Hydraulic valve blocks are widely used in industry, machinery, automobiles and other fields to achieve the control and regulation functions of various hydraulic systems.

[0003] During the drilling process, if the hydraulic valve block is not fixed properly, it will move or shake, resulting in inaccurate drilling position, thus affecting the processing accuracy. The existing drilling machine does not have a clamping tool, resulting in a high scrap rate when drilling the hydraulic valve block. Utility Model Content

[0021] like Figures 1 to 5 As shown, a chuck structure for a hydraulic valve block machine tool includes a chassis assembly 1, wherein the chassis assembly includes a bottom plate 11, which has a large area and rigidity and can effectively disperse and withstand the force and vibration during the processing. A center disc 12 is provided on the top of the bottom plate, and a mounting disc 31 is rotatably connected to the top of the center disc. The center disc serves as a rotation connection basis for the mounting disc 31, thereby ensuring the stability and accuracy of the mounting disc during the processing. A plurality of extension plates 13 are arranged in a circular array on the center disc, and a positioning mechanism 2 is provided on the extension plate. A plurality of clamping mechanisms 4 are provided on the mounting disc, and a hydraulic valve block 100 is clamped between the plurality of clamping mechanisms. The positioning mechanism is used to limit the relative rotation between the center disc and the mounting disc to ensure the positioning accuracy of the hydraulic valve block during the processing.

[0022] In at least one embodiment, the positioning mechanism includes a positioning pin 21 and a flexible spring 22, a through hole is provided on the extension plate, a positioning pin is installed in the through hole, a flexible spring is provided between the positioning pin and the extension plate, and in coordination therewith, a positioning ring 32 is provided at the bottom of the mounting plate, a plurality of positioning grooves 321 are provided on the positioning ring, and the positioning pin is inserted into the positioning groove under the action of the flexible spring to limit the relative rotation between the center disk and the mounting plate. The positioning mechanism effectively limits the relative rotation between the center disk and the mounting plate through the coordination of the positioning pin, the flexible spring and the positioning ring, thereby improving the positioning accuracy and stability of the hydraulic valve block during the processing process.

[0023] The solution is refined, and the flexible spring is sleeved on the locking pin.

[0024] In at least one embodiment, the clamping mechanism includes a rotating screw 41, a slider 42, a horizontal connecting plate 44 and a vertical clamping plate 45. A plurality of slide grooves 311 are provided on the top of the mounting plate. The slide grooves are slidably matched with sliders. The rotating screw passes through the mounting plate and extends into the slide grooves and matches with the sliders. The rotation of the rotating screw can drive the slider to move along the slide grooves. The slider is fixedly connected with a horizontal connecting plate by bolts 43, and the horizontal connecting plate is fixedly connected with a vertical clamping plate. Such a design enables the rotation of the rotating screw 41 to indirectly control the position of the vertical clamping plate 45, thereby realizing the clamping or releasing operation. Through the cooperation of the rotating screw, the slider, the horizontal connecting plate and the vertical clamping plate, the stable clamping and flexible adjustment of the hydraulic valve block are realized. Such a design enables the clamping mechanism to adapt to hydraulic valve blocks of different sizes and shapes, thereby improving the versatility and adaptability of the chuck structure.

[0025] Furthermore, the vertical clamping plate is provided with an anti-skid rubber layer 46. The anti-skid rubber layer can increase the friction between the vertical clamping plate and the hydraulic valve block, and prevent the hydraulic valve block from sliding or deflecting during the processing.

[0026] Further, such as Figure 4 The top of the vertical clamping plate is provided with a guide hole 451, a guide rod 47 is slidably fitted in the guide hole, a top pressure plate 48 is mounted on the guide rod, and a tension spring 452 is provided between the bottom of the guide hole and the guide rod.

[0027] The scheme is refined. The tension spring drives the top pressure plate to move toward the mounting plate. This design makes full use of the elastic force of the tension spring, ensuring that the top pressure plate exerts a uniform and stable pressure on the hydraulic valve block. At the same time, the tension spring can also play a role in buffering and absorbing vibrations, further improving the stability and reliability of the chuck structure.

[0028] Working method: place the hydraulic valve block 100 to be processed on the mounting plate 31, and drive the slider 42 to move in the slide groove 311 by rotating the lead screw 41, thereby driving the horizontal connecting plate 44 and the vertical clamping plate 45 connected thereto to move. Adjust the position of each clamping mechanism 4 so that the vertical clamping plate 45 gradually approaches the hydraulic valve block 100 until it is clamped. During the clamping process, the anti-slip rubber layer 46 can increase the friction between the vertical clamping plate 45 and the hydraulic valve block 100, preventing the hydraulic valve block 100 from sliding or deflecting during the processing.

[0029] After the hydraulic valve block 100 is clamped, the position of the mounting plate 31 is adjusted by rotating it to reach the predetermined processing position. During the rotation process, the locking mechanism 2 plays a key role. When the center disk 12 and the mounting plate 31 rotate relative to each other, the locking pin 21 is inserted into the locking groove 321 of the locking ring 32 under the action of the flexible spring 22, thereby limiting the relative rotation of the two and achieving precise positioning.

[0030] After the hydraulic valve block 100 is clamped by the clamping mechanism 4, the top pressure plate 48 moves toward the top of the hydraulic valve block 100 driven by the tension spring 452. The top pressure plate 48 and the vertical clamping plate 45 form a double clamping to ensure the stability of the hydraulic valve block 100 during the processing. After the hydraulic valve block 100 is stably clamped and positioned, the machine tool can be started to process it. After the processing is completed, the rotating screw 41 is rotated in the opposite direction to make the vertical clamping plate 45 release the hydraulic valve block 100. Move the top pressure plate 48 upward to make it leave the top of the hydraulic valve block 100. Take the processed hydraulic valve block 100 out of the mounting plate 31.

[0031] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.
