During the production process of an electricity meter, various parameters inside the electricity meter need to be set and calibrated through an electricity meter calibration bench.

Under the action of the baffle assembly 32, the outer baffle 26 slides and extends along the placement plate 24; after the movement of the placement plate 24 ends under the action of the moving assembly 31, the moving assembly 31 continues to act to lower the cover plate 20 to limit the electric energy meters to prevent the electric energy meters from shifting; the baffle assembly 32 continues to act, and the baffle assembly 32 drives the electric energy meters to contact the wiring terminal seat through the outer baffle 26 to perform meter calibration operations.

The other end of the first top spring 30 contacts the lower U-shaped frame 22.

[0036] When the moving component 31 is in use, start the dial indicator motor 39. The dial indicator motor 39 drives the rotating block 44 to slowly rotate. The rotating block 44 drives the driving block 36 to move through the sliding rod 43. Under the action of the second top spring 38, the driving block 36 drives the sliding cylinder 42 to slide along the guiding shaft 35 through the vertical shaft 37. The sliding cylinder 42 drives the placing plate 24 to move. The driving block 36 drives the slider 34 to slide along the sliding bracket 33; when the sliding cylinder 42 contacts the limiting block 40, the rotating block 44 continues to rotate, and the rotating block 44 drives the driving block 36 to slide along the vertical shaft 37 through the sliding rod 43; the driving block 36 drives the sliding plate 28 to move up and down through the cooperation of the slider 34 and the sliding bracket 33, and the sliding plate 28 drives the cover plate 20 to move up and down; that is, through the settings of the rotating block 44, the sliding rod 43, the guiding shaft 35, the sliding cylinder 42, the vertical shaft 37, etc., the driving block 36 moves up and down, horizontally, and up and down. When the driving block 36 moves up and down, it can drive the cover plate 20 to move up and down.

[0037] Further, as Fig. 9As shown, the baffle assembly 32 includes a vertical rod 54 fixed to the placement plate 24, a transverse rod 51 is slidably connected to the vertical rod 54, and the outer baffle 26 is slidably connected to the transverse rod 51; a telescopic rod 53 is fixed to the placement plate 24, a traction block 52 is fixed to the telescopic end of the telescopic rod 53, and the outer baffle 26 can slide up and down along the traction block 52; a mounting plate 41 is fixed to the drive housing 19, a sliding drive rod 45 is on the mounting plate 41, and a descending block is fixed to the end of the drive rod 45 close to the calibration motor 39; the drive A stopper is fixedly connected to the other end of the movable rod 45, a rising block is sleeved on the driving rod 45, and a driving spring 46 is provided between the rising block and the stopper; the end of the driving rod 45 close to the stopper is rotatably connected to a connecting rod 47, and an active rod 48 is rotatably connected to the connecting rod 47, the active rod 48 is rotatably connected to the placing plate 24, and an output rod 49 is fixedly connected to the end of the active rod 48 close to the placing plate 24; a connecting block 50 is fixedly connected to the outer baffle plate 26, a connecting groove is provided on the connecting block 50, and a roller matching the connecting groove is rotatably connected to the output rod 49.

[0038] When the baffle assembly 32 is in use, when the placement plate 24 slides along the turntable 14 to the upper feed conveyor belt 1, as shown in FIG. Fig. 9 As shown, at this time, the rising block moves in the direction away from the mounting plate 41, causing the driving spring 46 to reset and extend; when the descending block contacts the mounting plate 41, the driving rod 45 pulls the connecting rod 47, and the connecting rod 47 drives the output rod 49 to rotate through the active rod 48, and the output rod 49 cooperates with the connecting groove on the connecting block 50 through the roller to drive the outer baffle 26 to descend; when the placement plate 24 moves in the opposite direction, after the rising block contacts the mounting plate 41, under the action of the driving spring 46, the movement speed of the driving rod 45 is less than the movement speed of the placement plate 24, so that the driving The rod 45 drives the active rod 48 to rotate through the connecting rod 47, thereby raising the outer baffle plate 26, so that the rising and falling of the outer baffle plate 26 are automatically raised and lowered along with the movement of the placement plate 24, thereby improving the convenience of the present application; when the placement plate 24 is raised and lowered, the placement plate 24 drives the transverse rod 51 to slide along the vertical rod 54, and the placement plate 24 slides along the traction block 52; in addition, through the extension and retraction of the telescopic rod 53, the connecting telescopic rod 53 drives the outer baffle plate 26 to slide along the transverse rod 51 through the traction block 52, thereby driving the electric energy meter to move, and then contacting the connection terminal seat to perform the meter calibration operation.

[0040] The working process of the present invention is:

[0041] When the present invention is in use, the calibration device 2 in the present application is placed between the loading conveyor belt 1 and the packaging conveyor belt 3. The loading conveyor belt 1 continuously transports the electric energy meter to the calibration device 2, and the electric energy meter is calibrated by the calibration device 2. After the calibration is completed, the electric energy meter is moved to the packaging conveyor belt 3 for transportation, and then assembly and packaging operations are performed.

[0042] Specifically, the conveyor belt 8 is driven to move in steps by cooperating with the stepping motor 7 and the rotating roller, and the adjacent electric energy meters are divided by the partition 9, so that the electric energy meters are aligned with the placement plate 24; the meter calibration motor 39 is started, and the meter calibration motor 39 drives the rotating block 44 to rotate slowly, and the rotating block 44 drives the driving block 36 to move through the slide rod 43, and the driving block 36 drives the slide cylinder 42 to slide along the guide shaft 35 through the vertical shaft 37 under the action of the second top spring 38, and the slide cylinder 42 drives the placement plate 24 to move until it contacts the support frame 6 and stops, and the driving block 36 drives the slider 3 4 slides along the sliding frame 33; at the same time, the rising block moves away from the mounting plate 41, so that the driving spring 46 is reset and extended; when the descending block contacts the mounting plate 41, the driving rod 45 pulls the connecting rod 47, and the connecting rod 47 drives the output rod 49 to rotate through the active rod 48, and the output rod 49 drives the outer baffle 26 to descend and hide through the roller and the connecting groove on the connecting block 50; through the cooperation of the hydraulic rod 10 and the suction cup 11, the electric energy meter is moved to the placement plate 24 through the opening 4 on the support frame 6 to contact the inner baffle 25.

[0043] The calibration motor 39 moves in the reverse direction, and the placement plate 24 moves in the reverse direction. When the rising block contacts the mounting plate 41, under the action of the driving spring 46, the movement speed of the driving rod 45 is less than the movement speed of the placement plate 24, so that the driving rod 45 drives the active rod 48 to rotate through the connecting rod 47, thereby causing the outer baffle plate 26 to rise; when the slide cylinder 42 contacts the limit block 40, the rotating block 44 continues to rotate, and the rotating block 44 drives the driving block 36 to slide along the vertical axis 37 through the sliding rod 43; the driving block 36 cooperates with the sliding frame 33 through the slider 34 to drive the sliding plate 28 to move downward, and the sliding plate 28 drives the cover plate 20 to move downward to limit the electric energy meter and prevent the electric energy meter from shifting; the connecting telescopic rod 53 is contracted, and the connecting telescopic rod 53 drives the outer baffle plate 26 to slide along the transverse rod 51 through the traction block 52, thereby driving the electric energy meter to move and contact the wiring terminal seat to perform the calibration operation.

The electric energy meter is moved to the packaging conveyor belt 3 by cooperating with the placement plate 24, the outer baffle plate 26, the suction cup 11, and the hydraulic rod 10, so that the production process of the electric energy meter is not interrupted, thereby improving the efficiency of the electric energy meter production in this application.
