Threaded blocks are threaded to the outer circumference of both ends of the bidirectional lead screw, and clamping blocks are fixedly installed on the top of each of the two threaded blocks. In this multi-station composite processing device for valve core seats, when clamping valve core seats of different sizes or slightly different shapes, the limiting block can slide in the slide groove through the sliding rod.

[0002] The valve seat is a key basic component in hydraulic and pneumatic systems. It is usually part of the valve body or valve sleeve, used to install and fix the valve core, and to guide and seal the movement of the valve core.

Detailed Implementation

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-6 As shown, this utility model discloses a multi-station composite processing device for valve core seats, including a worktable 1, an operating table 2 rotatably connected to the surface of the worktable 1, a base 3 fixedly installed at the bottom of the worktable 1, a movable frame 4 slidably connected to one side of the upper surface of the worktable 1, clamping chambers 5 fixedly embedded around the operating table 2, a micro motor 6 fixedly installed at one end of each clamping chamber 5, the output end of the micro motor 6 passing through the clamping chamber 5 and being driven by a bidirectional lead screw 7, threaded blocks 8 threadedly connected to the outer periphery of both ends of the bidirectional lead screw 7, clamping blocks 9 fixedly installed on the top of each of the two threaded blocks 8, and cavities 10 opened on the inner side of each of the two clamping blocks 9.

[0026] The cavity 10 has a fixed horizontal plate 11 inside and a number of limiting blocks 12 slidably connected inside. Several steel balls 13 are arranged on the side of the limiting blocks 12 closest to the inside of the clamping block 9. The limiting blocks 12 and the steel balls 13 cooperate with each other. The limiting blocks 12 can slide within the slide groove 14 via the slide rod 15. The other end of the limiting blocks 12 pushes the steel balls 13 to flow until they can no longer flow, conforming to the contour of the workpiece to ensure clamping stability and accuracy.

[0027] The horizontal plate 11 has several sliding grooves 14 on its surface. The bottom of several limiting blocks 12 is fixedly connected to sliding rods 15, and the sliding rods 15 slide in correspondence with the interior of the sliding grooves 14. The clamping block 9 has a sliding groove 16 on one side, and a reset rod 17 is slidably connected inside the sliding groove 16. The reset rod 17 contacts the sliding rod 15 and slides in the sliding groove 14 through the sliding rod 15 to guide the movement of the limiting block 12. When it is necessary to reset the limiting block 12, the reset rod 17 pushes the sliding rod 15 under manual force, thereby driving the limiting block 12 to return to its position.

[0028] The bottom of the operating table 2 is fixedly connected to the rotating plate 18 through the workbench 1. The lower end of the workbench 1 is fixedly installed with a reduction motor 19 through a connecting plate. The output end of the reduction motor 19 is connected to a rotating wheel 20, and the rotating wheel 20 is in contact with the rotating plate 18. The reduction motor 19 drives the rotating wheel 20 to rotate, and the rotating wheel 20 drives the extension plate 21 to rotate, so that the drive column 22 at the lower end of the extension plate 21 extends into a placement slot 23 of the rotating plate 18, driving the operating table 2 to rotate intermittently.

[0029] The upper end of the rotating wheel 20 is fixedly connected to an extension plate 21, the lower end of the extension plate 21 is fixedly connected to a drive column 22, and the rotating plate 18 is provided with placement slots 23 on all four sides, and the placement slots 23 are engaged with the drive column 22.

[0030] The worktable 1 has two symmetrically rotatably connected threaded rods 24 on both sides of one end, and the threaded rods 24 are threaded to the lower ends of both sides of the movable frame 4. One end of each threaded rod 24 is fixedly connected to a bevel gear 25, and the outer circumference of each bevel gear 25 is meshed with a bevel gear 26. The two bevel gears 26 are fixedly connected by a connecting column. A drive motor 27 is fixedly installed on one side of the worktable 1, and the output end of the drive motor 27 is connected to one of the bevel gears 25. Through the transmission mechanism of the bevel gear 26 and bevel gear 25, the drive motor 27 synchronously drives the threaded rods 24 on both sides to rotate, so that the movable frame 4 makes a smooth linear reciprocating motion along the worktable 1 under the drive of the threaded rods 24.

[0031] The top of the mobile frame 4 is fixedly embedded with a hydraulic rod 28, the output end of the hydraulic rod 28 is fixedly connected to a bracket 29, and a drilling machine 30 is fixedly installed on one side of the bracket 29.

[0032] Working principle: During use, the operator places the valve core seat workpiece to be processed between the clamping blocks 9 at any station on the operating table 2. The micro motor 6 corresponding to that station is started, driving the bidirectional lead screw 7 to rotate. The two threaded blocks 8 drive the clamping blocks 9 to move towards each other. The limiting block 12 and steel ball 13 on the inner side of the clamping block 9 contact and clamp the workpiece. Since the limiting block 12 is slidable, it can adapt to the size of the workpiece and achieve stable clamping. After a workpiece is clamped, the reduction motor 19 is started, driving the rotating wheel 20 to rotate. The rotating wheel 20 drives the extension plate 21 to rotate, so that the drive column 22 at the lower end of the extension plate 21 extends into a placement slot 23 of the rotating plate 18, pushing the rotating plate 18 to rotate 90°. The rotating plate 18 drives the operating table 2 to rotate one station, transferring the clamped workpiece to the processing area. At the same time, the previous workpiece is transferred to the next processing or unloading position. The drive motor 27 is started, driving the bevel gear 26 through the bevel gears. The wheel 25 drives the threaded rods 24 on both sides to rotate synchronously. The moving frame 4 moves linearly along the worktable 1 under the drive of the threaded rods 24, so that the drilling machine 30 is aligned with the workpiece to be processed at the current station. The hydraulic rod 28 is activated, and its piston rod extends to push the bracket 29 and the drilling machine 30 to feed downward smoothly to complete the drilling. The hydraulic rod 28 retracts, the drilling machine 30 resets, and the next workpiece is drilled. At the same time, the operating table 2 is indexed again, the drilled workpiece is transferred away, and the new workpiece to be processed is transferred into the processing area, realizing continuous and cyclic processing of multiple stations.
