Description

Technical Field

[0001] This utility model relates to the field of metrological verification technology, and in particular to a workbench for metrological verification. Background Technology

[0002] Verification refers to the activity by which a legally authorized metrology department or organization, in accordance with verification procedures, conducts experiments and provides proof to determine whether the indication error of a measuring instrument meets the specified requirements. Examples include the verification of various data during water quality testing, the verification of data during indoor air testing, and the verification of the length of various instruments. All of these require professional personnel to perform metrological verification operations. Since various instruments are needed to assist in the verification process, a workbench is required to provide a platform for verification personnel to complete the verification operations.

[0003] Most existing calibration workbenches are fixed structures. Since metrological calibration requires staff to frequently change auxiliary instruments, their posture needs to change often. However, since each staff member has a different height, the fixed structure of the workbench causes some staff members to repeatedly bend over during calibration operations. When they sit down, they find the table too high, resulting in high pressure on their lower back and affecting their health. It is also difficult to adjust the workbench according to the actual needs of the staff, so there is room for improvement. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a metrological verification workbench.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A metrological verification workbench includes a workbench body. A stabilizing component is fixedly connected to the lower surface of the workbench body. Two adjusting components are fixedly connected to the lower surface of the workbench body. Each adjusting component includes a strip frame. Two threaded rods are rotatably connected to the inner top wall of the strip frame. A servo motor is fixedly connected to the inner top wall of the strip frame. The output end of the servo motor is fixedly connected to the top end of any of the threaded rods. A transmission sprocket is fixedly connected to the surface of each of the two threaded rods. A chain is drivingly connected between the two transmission sprockets. A rectangular frame is fixedly connected to the lower surface of the strip frame. Two limiting rods are fixedly connected to the inner bottom wall of the rectangular frame. Slider blocks are slidably connected to the left and right inner walls of the rectangular frame. A support frame is fixedly connected to the opposite face of the two sliders. A threaded groove adapted to the threaded rods is opened on the upper surface of the support frame. A rubber pad is fixedly connected to the lower surface of the support frame.

[0007] Preferably, the lower surface of the strip frame and the upper surface of the rectangular frame are both provided with circular through holes that are adapted to the threaded rod.

[0008] Preferably, the two sliders are slidably connected to the surfaces of the two limiting rods, and the lower surface of the rectangular frame is provided with a rectangular hole that matches the support frame.

[0009] Preferably, the stabilizing component includes a circular sleeve, a circular disk slidably connected to the inner wall of the circular sleeve, a support rod fixedly connected to the lower surface of the circular disk, a positioning frame fixedly connected to the bottom end of the support rod, and a circular hole adapted to the support rod being opened at the bottom end of the circular sleeve.

[0010] Preferably, a positioning plate is fixedly connected to the inner wall of the positioning frame, a positioning hole is opened on the upper surface of the positioning plate, a cylinder is fixedly connected to the inner wall of the positioning hole, and a suction cup is fixedly connected to the bottom end of the cylinder.

[0011] Preferably, the top end of the cylinder is threaded with a lead screw, and the bottom end of the lead screw is rotatably connected to a piston, which is slidably connected to the inner wall of the cylinder.

[0012] The beneficial effects of this utility model are as follows:

[0013] By adjusting the component settings, the support frame can be moved up and down within the rectangular frame via a servo motor, transmission sprocket, chain, and threaded rod, thus freely adjusting the height of the workbench. This allows the calibration personnel to determine the appropriate workbench height based on their own height and build, greatly reducing physical stress during operation and improving calibration efficiency. Furthermore, the stabilizing components utilize negative pressure adsorption to increase the connection strength between the workbench and the ground, ensuring that the workbench will not tip over due to collisions, resulting in greater stability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example:

[0020] Reference Figure 1-3 A metrological verification workbench includes a workbench body 1. A stabilizing component is fixedly connected to the lower surface of the workbench body 1. Two adjusting components are fixedly connected to the lower surface of the workbench body 1. The adjusting components include a strip frame 2. Two threaded rods 3 are rotatably connected to the inner top wall of the strip frame 2. A servo motor 4 is fixedly connected to the inner top wall of the strip frame 2. The output end of the servo motor 4 is fixedly connected to the top end of any threaded rod 3. A transmission sprocket 5 is fixedly connected to the surface of each of the two threaded rods 3. A chain 6 is connected between the two transmission sprockets 5. A rectangular frame 7 is fixedly connected to the lower surface of the strip frame 2. Two limiting rods 8 are fixedly connected to the inner bottom wall of the rectangular frame 7. Slider 9s are slidably connected to the left and right inner walls of the rectangular frame 7. A support frame 10 is fixedly connected to the opposite face of the two sliders 9. A threaded groove adapted to the threaded rod 3 is opened on the upper surface of the support frame 10. A rubber pad 11 is fixedly connected to the lower surface of the support frame 10.

[0021] Both the lower surface of the strip frame 2 and the upper surface of the rectangular frame 7 are provided with circular through holes that are compatible with the threaded rods 3. The two sliders 9 are slidably connected to the surfaces of the two limit rods 8 respectively. The lower surface of the rectangular frame 7 is provided with rectangular holes that are compatible with the support frame 10. After the two servo motors 4 are turned on, the two sets of threaded rods 3 can be rotated synchronously through the setting of two sets of transmission sprockets 5 and chains 6. This allows the four support frames 10 to move up and down on the inner wall of the rectangular frame 7, thereby freely changing the height of the workbench body 1. This allows the inspector to determine the appropriate height according to their own height and inspection posture, making it more user-friendly for the inspector. Furthermore, the setting of the sliders 9 and limit rods 8 ensures that the support frame 10 will not detach or shift, resulting in higher stability.

[0022] The stabilizing assembly includes a circular sleeve 12, with a circular disk 13 slidably connected to the inner wall of the sleeve 12. A support rod 14 is fixedly connected to the lower surface of the circular disk 13, and a positioning frame 15 is fixedly connected to the bottom end of the support rod 14. A circular hole adapted to the support rod 14 is opened at the bottom end of the circular sleeve 12. A positioning plate 16 is fixedly connected to the inner wall of the positioning frame 15, and a positioning hole is opened on the upper surface of the positioning plate 16. A cylinder 17 is fixedly connected to the inner wall of the positioning hole, and a suction cup 18 is fixedly connected to the bottom end of the cylinder 17. A lead screw 19 is threadedly connected to the top end of the cylinder 17, and a piston 20 is rotatably connected to the bottom end of the lead screw 19. The piston 20 is slidably connected to the inner wall of the cylinder 17. After the suction cup 18 contacts the ground, the lead screw 19 is rotated, causing the lead screw 19 to drive the piston 20 to rise inside the cylinder 17. The piston 20 can extract the air from the suction cup 18 through the cylinder 17, thereby creating a negative pressure inside the suction cup 18, which firmly adheres to the ground. Thus, the cylinder 17, positioning plate 16, positioning frame 15, support rod 14 and circular sleeve 12 can improve the stability of the workbench body 1, ensuring that the workbench body 1 will not tip over after being hit. In addition, the support rod 14 can drive the circular disc 13 to move up and down inside the circular sleeve 12, which can easily move freely according to the height of the workbench body 1, and has high flexibility.

[0023] Working principle: When the height of the workbench body 1 needs to be adjusted, the two servo motors 4 are first turned on. The two servo motors 4 can start synchronously, and through the transmission sprockets 5 and chains 6, they synchronously drive the two sets of threaded rods 3 to rotate. At this time, the threaded rods 3 can drive the support frame 10 to move up and down, thereby changing the distance between the support frame 10 and the rectangular frame 7. This allows the height of the workbench body 1 to be freely changed. Furthermore, the support frame 10 is limited by the slider 9 and the limiting rod 8, preventing it from detaching or shifting. This results in higher stability and greater convenience for inspectors of different heights. The operator uses the workbench body 1, which is also convenient for inspection operations in different body postures, making it more flexible. After the suction cup 18 contacts the ground, the piston 20 can be driven to rise by rotating the screw 19, thereby extracting the air in the suction cup 18 through the cylinder 17. The suction cup 18 increases the connection strength between the workbench body 1 and the ground, ensuring that the workbench body 1 will not collapse after being impacted, making it more stable. In addition, the support rod 14 can drive the circular disk 13 to move up and down in the circular sleeve 12, which can be adjusted according to the height of the workbench body 1.
