Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically to a valve casting processing production equipment. Background Technology

[0002] When valve castings are machined (such as cutting, drilling, milling, etc.), they need to be firmly clamped to prevent displacement or vibration during the machining process.

[0003] Traditional valve assembly clamping devices can only clamp a single material. When processing a batch of materials of the same specification, it is necessary to repeatedly load and unload the materials, which is inconvenient to operate. In addition, the workbench is not easy to clean, making it inconvenient to use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a valve casting processing and production equipment.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a valve casting processing production equipment, including a worktable, a feeding assembly, and a clamping assembly. The feeding assembly includes a motor, a transmission rod, a worm gear, a worm wheel, a first support, a second support, and a screw. The first supports are symmetrically arranged on the left and right sides below the worktable. The transmission rod is rotatably arranged between two sets of first supports. The output end of the motor passes through one set of first supports and is connected to the transmission rod. Several sets of symmetrically arranged second supports are also arranged on the front and rear sides below the worktable. The worm wheel is provided with screws rotatably connected to the second supports on its front and rear sides. The worktable is provided with sliding holes adapted to the screws. The transmission rod is provided with worm gears that mesh with the worm wheel.

[0008] The clamping assembly includes a slider, a mounting base, and a clamp. Several sets of mounting bases are symmetrically arranged on the front and rear sides of the worktable. A slider that passes through the sliding hole is arranged below the mounting base. The slider is threadedly connected to the screw. The clamp is also arranged at one end of the mounting base near the center of the worktable.

[0009] To provide stable support for the workbench, this utility model is improved by providing support legs at the four corners below the workbench.

[0010] To facilitate the collection of waste materials, this utility model is improved by providing a support plate at each of the four corners below the workbench, and a support frame with an opening at the top is provided on the support plate.

[0011] Preferably, two sets of baffles are symmetrically arranged on the front and rear sides below the worktable. The baffles are arranged on the front and rear sides of several sets of worm gears, and the screw passes through the baffles.

[0012] To facilitate the assembly and disassembly of the clamp, this utility model is improved in that the clamp is connected to the mounting base via a connector, the connector including a guide block, a stud, and a nut. The mounting base is provided with a guide groove, and a guide block that inserts into the guide groove is provided on one side of the clamp. Studs that penetrate the mounting base are also provided at both ends of one side of the clamp, and nuts that connect to the studs are provided on the mounting base.

[0013] Preferably, the motor is a servo motor.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a valve casting processing equipment, which has the following beneficial effects:

[0016] Traditional valve casting processing equipment can only clamp materials individually, requiring frequent loading and unloading for batch processing. This new equipment, however, features several sets of mounting seats and clamps symmetrically arranged on both sides of the worktable. Through the transmission structure of the feed assembly, multiple valve castings of the same specification can be clamped simultaneously. A motor-driven transmission rod, via worm gears, worm wheels, and a screw, moves the mounting seats, achieving synchronous positioning and clamping of multiple castings. This significantly reduces loading and unloading time and the number of operations, greatly improving the efficiency of batch processing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 A valve casting processing production equipment includes a worktable 1, a feeding assembly, and a clamping assembly. The feeding assembly includes a motor 2, a transmission rod 3, a worm gear 4, a worm wheel 5, a first support 6, a second support 7, and a screw 8. The first support 6 is symmetrically arranged on the left and right sides below the worktable 1. The transmission rod 3 is rotatably arranged between two sets of first supports 6. The output end of the motor 2 passes through one set of first supports 6 and is connected to the transmission rod 3. Several sets of second supports 7 are also symmetrically arranged on the front and rear sides below the worktable 1. The worm wheel 5 is provided with screws 8 rotatably connected to the second supports 7 on its front and rear sides. The worktable 1 is provided with sliding holes adapted to the screws 8. The transmission rod 3 is provided with worm gear 4 that meshes with the worm wheel 5.

[0024] Motor 2, serving as the power source for the entire feed assembly, is a servo motor capable of precisely controlling speed and direction of rotation. The output of motor 2 passes through a first bracket 6 and connects to the transmission rod 3. When motor 2 starts, its rotation drives the transmission rod 3 to rotate synchronously. The transmission rod 3 is equipped with worm gears 4. Several sets of symmetrically arranged second brackets 7 are located on the front and rear sides below the worktable 1. Worm wheels 5 are rotatably connected to the second brackets 7 via bearings and other components, with the worm gears 4 meshing with them. When the transmission rod 3 rotates, the worm gears 4 drive the worm wheel 5 to rotate. The worm gear transmission has a large transmission ratio, enabling speed reduction and torque increase, and also possesses self-locking properties, meaning the worm wheel 5 will not rotate on its own without external force. This ensures stable transmission of the subsequent screw 8. Screws 8, rotatably connected to the second brackets 7, are located on the front and rear sides of the worm wheel 5. When the worm wheel 5 rotates, it drives the connected screws 8 to rotate synchronously. The screw 8 is fitted with a sliding hole on the worktable 1, and the slider 9 below the mounting base 10 is threadedly connected to the screw 8. Rotation of the screw 8 causes the threaded slider 9 to move within the sliding hole along the axial direction of the screw 8.

[0025] In this embodiment, the clamping assembly includes a slider 9, a mounting base 10, and a clamp 11. Several sets of mounting bases 10 are symmetrically arranged on the front and rear sides of the worktable 1. A slider 9, passing through a sliding hole, is disposed below each mounting base 10. The slider 9 is threadedly connected to the screw 8. A clamp 11 is also disposed at the end of each mounting base 10 near the center of the worktable 1. When the screw 8 rotates, the slider 9 moves within the sliding hole, thereby moving the mounting base 10. The symmetrical arrangement of several sets of mounting bases 10 on the front and rear sides of the worktable 1 allows for synchronous movement of multiple mounting bases 10 through the rotation of the screw 8. A clamp 11 is disposed at the end of each mounting base 10 near the center of the worktable 1. When the mounting base 10 moves to a suitable position, the clamp 11 can clamp the valve casting placed near the center of the worktable 1.

[0026] The workbench 1 is equipped with four support legs 12 at its four corners. The function of the support legs 12 is to provide stable support for the workbench 1. They evenly distribute the weight of the workbench 1 and all its components onto the ground, ensuring that the workbench 1 remains stable during processing, reducing shaking and vibration, thereby providing a stable platform for processing valve castings and helping to improve processing accuracy.

[0027] Support plates 13 are installed at the four corners of the workbench 1, and support frames 14 with openings at the top are installed on the support plates 13. During the valve casting process, waste chips will fall from the surface of the workbench 1. Due to the opening design of the support frames 14, the waste chips will fall into the support frames 14. The support plates 13 serve to support the support frames 14, allowing the waste chips to be collected in the support frames 14, facilitating subsequent cleaning and keeping the surface of the workbench 1 clean. Two sets of baffles 15 are also symmetrically arranged on the front and rear sides of the workbench 1. The baffles 15 are located on the front and rear sides of several sets of worm gears 5, and the screw 8 passes through the baffles 15. The main function of the baffles 15 is to prevent waste chips and debris generated during the processing from entering the transmission components such as the worm gears 5 and the screw 8. If waste chips or debris enter the transmission components, it may cause wear, jamming, or other malfunctions, affecting the normal operation of the equipment. The baffle 15 can effectively block these foreign objects, protect the normal operation of the transmission components, and improve the reliability and service life of the equipment.

[0028] In practical use, the clamp 11 is connected to the mounting base 10 via a connector, which includes a guide block 16, a stud 17, and a nut 18. The mounting base 10 has a guide groove. One side of the clamp 11 has a guide block 16 that inserts into the guide groove. Both ends of one side of the clamp 11 have studs 17 that penetrate the mounting base 10. The mounting base 10 has nuts 18 that connect to the studs 17. The clamp 11 is connected to the mounting base 10 via the connector (guide block 16, stud 17, and nut 18). The guide block 16 engages with the guide groove on the mounting base 10, facilitating the positioning and installation of the clamp 11. The stud 17 penetrates the mounting base 10 and is fixed by the nut 18, ensuring the clamp 11 is securely mounted on the mounting base 10. By adjusting the position and clamping tightness of the clamp 11, valve castings of different specifications can be stably clamped.
