Description

Technical Field

[0001] This utility model relates to the technical field of worktables for parts processing, specifically a high-stability worktable for precision parts processing. Background Technology

[0002] The worktable plays a crucial role in the machining of precision parts. First, the main functions of the worktable include fixing the workpiece, providing a grinding reference, adapting to different workpieces, and working with fixtures. Through these functions, the worktable ensures the stability and accuracy of the machining process.

[0003] In existing technologies, metal chips and dust are generated during the machining of parts, which are difficult to clean on the surface of the worktable. The impurities remaining on the worktable will affect the fixing and clamping accuracy of the parts on the worktable, and thus affect the subsequent machining accuracy of the parts. To address this issue, we propose a high-stability worktable for precision parts machining. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable worktable for machining precision parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-stability worktable for precision parts machining, comprising a mounting frame, a table surface on the mounting frame, the table surface being rotatably connected to the mounting frame via a mounting shaft, a gear being sleeved on the mounting shaft, a rack being slidably mounted inside the mounting frame, the rack meshing with the gear, a first cylinder being mounted inside the mounting frame, the rack being connected to the output end of the piston rod of the first cylinder, a fixed frame being fixedly mounted on the mounting frame, a movable frame being slidably mounted inside the fixed frame, multiple sets of high-pressure nozzles being equidistantly distributed on the movable frame, a dust suction head being fixedly mounted on the movable frame, the dust suction head and the high-pressure nozzles being correspondingly arranged with respect to the surface of the table surface, and four sets of symmetrically distributed locking blocks being slidably mounted inside the mounting frame, all four sets of locking blocks being movably engaged with the table surface.

[0006] As a further preferred embodiment of this technical solution, the mounting bracket is provided with a first solenoid valve, which is connected to the inlet and outlet ports of the first cylinder via pipes.

[0007] As a further preferred embodiment of this technical solution, the fixed frame is provided with a lead screw, the two ends of which pass through the fixed frame and are rotatably connected to the fixed frame through bearings, and the lead screw passes through the movable frame and is threadedly connected to the movable frame.

[0008] As a further preferred embodiment of this technical solution, a dust collection box is provided below the fixing frame, and an installation cover is threaded onto the dust collection box. A filter screen is embedded in the installation cover, and a centrifugal fan is installed inside the installation cover. An installation ring is threaded into the dust collection box, and a filter screen cover is threaded onto the bottom of the installation ring. The suction head is fixedly connected to the dust collection box through a connecting pipe.

[0009] As a further preferred embodiment of this technical solution, each of the four sets of locking blocks is fixedly installed with an adjusting rod below it. Two sets of symmetrically distributed first sliding rods are slidably installed in the mounting frame, and two sets of symmetrically distributed second sliding rods are slidably installed in the mounting frame. The two sets of first sliding rods and second sliding rods are perpendicular to each other. The four sets of locking blocks are slidably connected to a set of first sliding rods and a set of second sliding rods respectively through the adjusting rods. A second solenoid valve is provided in the mounting frame.

[0010] As a further preferred embodiment of this technical solution, two sets of symmetrically distributed second cylinders are provided between each of the two sets of first slide rods and second slide rods. Each set of second solenoid valves is correspondingly provided with the two sets of second cylinders. The second solenoid valves are fixedly connected to the inlet and outlet ports of the corresponding two sets of second cylinders through pipes. Each of the two sets of first slide rods and second slide rods is fixedly connected to the output end of the piston rod of a set of second cylinders.

[0011] This utility model provides a highly stable worktable for precision parts machining, which has the following advantages:

[0012] (1) This utility model uses the gear and rack mechanism to enable the mounting shaft to rotate the table 180 degrees on the mounting frame. The high-pressure nozzle and dust suction head, together with the dust collection box and the centrifugal fan in the mounting cover, thoroughly clean the surface of the table facing down. This effectively ensures the cleanliness of the work surface and avoids the presence of impurities or dust affecting the machining accuracy of the parts and the working stability of the workbench. At the same time, the other side of the table is cleaned simultaneously, ensuring that the other side can continue to be used for parts processing after one side of the table is used, thus effectively ensuring the machining efficiency of the parts.

[0013] (2) This utility model achieves the adjustment of the distance between the four sets of adjusting rods and the fixedly installed clips on the adjusting rods by moving the two sets of symmetrically distributed first and second sliding rods. In this way, the table can be quickly snapped into place after the table flipping adjustment is completed, ensuring high stability of the table during operation and avoiding the instability of the table from affecting the precision machining of parts.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1-5As shown, in this embodiment, a high-stability workbench for precision parts machining includes a mounting frame 1, a table surface 2 on the mounting frame 1, the table surface 2 being rotatably connected to the mounting frame 1 via a mounting shaft 3, a gear 4 being sleeved on the mounting shaft 3, a rack 5 being slidably mounted inside the mounting frame 1, the rack 5 being meshed with the gear 4, a first cylinder 6 being mounted inside the mounting frame 1, the rack 5 being connected to the output end of the piston rod of the first cylinder 6, a fixed frame 13 being fixedly mounted on the mounting frame 1, a movable frame 14 being slidably mounted inside the fixed frame 13, multiple sets of high-pressure nozzles 15 being equidistantly distributed on the movable frame 14, a dust suction head 17 being fixedly mounted on the movable frame 14, the dust suction head 17 and the high-pressure nozzles 15 being correspondingly arranged with respect to the surface of the table surface 2, and four sets of symmetrically distributed locking blocks being slidably mounted inside the mounting frame 1. 7. All four sets of locking blocks 7 are movably engaged with the tabletop 2. The mounting frame 1 is equipped with a first solenoid valve 24, which is connected to the inlet and outlet of the first cylinder 6 through pipes. The fixed frame 13 is equipped with a lead screw 16, the two ends of which pass through the fixed frame 13 and are rotatably connected to the fixed frame 13 through bearings. The lead screw 16 passes through the movable frame 14 and is threadedly connected to the movable frame 14. A dust collection box 19 is provided below the fixed frame 13. A mounting cover 20 is threaded onto the dust collection box 19. A filter screen 25 is embedded in the mounting cover 20. A centrifugal fan 21 is installed inside the mounting cover 20. A mounting ring 22 is threaded into the dust collection box 19. A filter screen cover 23 is threaded onto the mounting ring 22. The suction head 17 is fixedly connected to the dust collection box 19 through a connecting pipe 18. The mounting frame 1 The first solenoid valve 24 and the first cylinder 6 are activated, causing the rack 5 to slide. This, in conjunction with the gear 4 meshing with it, causes the mounting shaft 3 to rotate the table 2 180 degrees on the mounting frame 1. The side that was originally at the bottom and met the cleanliness standard is flipped to the top to continue parts processing, while the side contaminated with impurities or dust is flipped to the bottom and aligns with the high-pressure nozzle 15 and the vacuum head 17. The motor in the fixed frame 13 drives the lead screw 16 to rotate, and the limiting action of the fixed frame 13 enables the moving frame 14 to move the high-pressure nozzle 15. The high-pressure nozzle 15 on the moving frame 14 is connected to an air pump through a pipe. Under the action of high-pressure airflow, some of the impurities adhering to the table 2 are blown off, achieving initial cleaning of the table 2. The fixed frame 14 then... The suction head 17, mounted on the movable frame 14, moves synchronously with the frame. The motor in the mounting cover 20 drives the centrifugal fan 21 to start, and the blades throw air outwards from the center, creating a partial vacuum at the connection between the dust collection box 19 and the connecting pipe 18. The suction head 17 draws residual impurities from the worktable 2, along with the air, into the dust collection box 19 through the suction head 17 and connecting pipe 18. After filtration, the dust and impurities remain on the surface of the filter screen 23. The air passes through the centrifugal fan and the filter screen 25, completing a secondary cleaning of the worktable 2. This ensures the effective cleanliness of the worktable 2 for future use and prevents residual impurities from the worktable 2 parts processing from affecting the positioning accuracy and processing stability of subsequent parts processing, and from accelerating equipment wear.The high-pressure nozzle 15 on the movable frame 14 is positioned low, and when the vacuum head 17 is located on one side of the fixed frame 13, the movable frame 14 and the vacuum head 17 will not affect the rotation of the tabletop 2.

[0022] like Figure 2 and Figure 4 As shown, each of the four sets of locking blocks 7 has an adjusting rod 8 fixedly installed below it. Two sets of symmetrically distributed first sliding rods 9 are slidably installed inside the mounting frame 1, and two sets of symmetrically distributed second sliding rods 10 are slidably installed inside the mounting frame 1. The two sets of first sliding rods 9 and second sliding rods 10 are perpendicular to each other. The four sets of locking blocks 7 are slidably connected to one set of first sliding rods 9 and one set of second sliding rods 10 respectively via the adjusting rod 8. A second solenoid valve 12 is provided inside the mounting frame 1. Two sets of symmetrically distributed second cylinders 11 are provided between each of the two sets of first sliding rods 9 and second sliding rods 10. Each set of second solenoid valves 12 is connected to one of the two sets of second cylinders 11. Cylinder 11 is set accordingly. The second solenoid valve 12 is fixedly connected to the inlet and outlet ports of the corresponding two sets of second cylinders 11 through pipes. The two sets of first slide rods 9 and second slide rods 10 are fixedly connected to the output end of the piston rod of one set of second cylinders 11. After the table 2 is flipped, the second solenoid valve 12 and the second cylinder 11 in the mounting bracket 1 are activated. The two sets of first slide rods 9 and second slide rods 10 slide inward synchronously, thereby driving the four sets of adjusting rods 8 and the locking block 7 to slide inward synchronously and lock with the flipped table 2, thereby further reinforcing the table 2 and ensuring the stability of the workbench.

[0023] This utility model provides a high-stability worktable for precision parts processing. The specific working principle is as follows: The first solenoid valve 24 and the first cylinder 6 in the mounting frame 1 activate and drive the rack 5 to slide. This, in conjunction with the gear 4 meshing with it, causes the mounting shaft 3 to rotate the table surface 2 180 degrees on the mounting frame 1. The side that was originally at the bottom and met the cleanliness standard is flipped to the top to continue parts processing, while the side contaminated with impurities or dust is flipped to the bottom and aligns with the high-pressure nozzle 15 and the suction head 17. The motor in the fixed frame 13 drives the lead screw 16 to rotate, and the limiting action of the fixed frame 13 enables the moving frame 14 to move the high-pressure nozzle 15. The high-pressure nozzle 15 on the moving frame 14 is connected to an air pump through a pipe. Under the action of high-pressure airflow, some impurities adhering to the table surface 2 are blown off, achieving initial cleaning of the table surface 2. The suction head 17, fixedly mounted on the moving frame 14, moves synchronously with the moving frame 14. The motor in the mounting cover 20 drives... When the centrifugal fan 21 starts, the blades throw air outward from the center, creating a partial vacuum at the connection between the dust collection box 19 and the connecting pipe 18. The dust suction head 17 sucks the residual impurities on the table 2, along with the air, into the dust collection box 19 through the dust suction head 17 and the connecting pipe 18. After filtration, the dust and impurities remain on the surface of the filter screen 23. The gas passes through the centrifugal fan and the filter screen 25 and leaves, completing the secondary cleaning of the table 2. This ensures the effective cleanliness of the table 2 for the next use and avoids the impact of residual impurities on the positioning accuracy and processing stability of subsequent parts processing, as well as the aggravation of equipment wear. After the table 2 is flipped, the second solenoid valve 12 and the second cylinder 11 in the mounting bracket 1 are activated. The two sets of first slide rods 9 and second slide rods 10 slide inward synchronously, thereby driving the four sets of adjusting rods 8 and the locking block 7 to slide inward synchronously and engage with the flipped table 2, further reinforcing the table 2 and ensuring the stability of the workbench.
