DETAILED DESCRIPTION

[0047] The following specific embodiments illustrate the embodiments of the utility model, and those skilled in the art can easily understand other advantages and effects of the utility model from the disclosed content of the specification, obviously, the described embodiments are a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0048] Please refer to Figures 1-7 , now the utility model discloses a locking screw machine for electric energy meter is explained, the utility model has 6 parts compositions, as shown in Figure 1 、 Figure 2 、 Figure 3 The utility model discloses a locking screw machine for electric energy meter, the utility model has 6 parts compositions, as shown in

[0049] In the embodiment, the tooling turntable 2 is used to place the electric energy meter to be processed; the nail feeding machine body 6 is used to provide the screw to the operator; the screw locking machine body 3 is used to tighten the screw on the electric energy meter; and the lower table conveying device 5 is used to take down the electric energy meter after being tightened and send it to the subsequent conveying mechanism, such as a conveying belt or a transfer device.

[0050] The in-place detection assembly 4 is used to detect whether there is a screw to be tightened on the electric energy meter, and the in-place detection assembly 4 can be linked with the overall device. As a possible embodiment, the in-place detection assembly 4 is linked with the tooling turntable 2 and the screw locking machine body 3, when the in-place detection assembly 4 detects that there is no screw on the electric energy meter, the tooling turntable 2 and the screw locking machine body 3 stop working and wait for the operator to re-pre-tighten the screw. As a possible embodiment, an alarm is installed on the outer cover 11, and the in-place detection assembly 4 is electrically connected with the alarm, when the in-place detection assembly 4 detects that there is no screw on the electric energy meter, the alarm gives an alarm, and the tooling turntable 2 and the screw locking machine body 3 can be stopped working in cooperation.

[0051] By setting the in-place detection assembly 4, it can automatically and accurately detect whether there is a pre-tightened screw on the electric energy meter. When it is detected that the screw is missing, the system can prompt the operator to handle in time through alarm or shutdown, and the original lagging manual inspection is changed to front-end automatic inspection in the production line, and the rear-end inspection is changed to front-end inspection, thereby effectively intercepting the subsequent locking process failure caused by missing screws and reducing the quality risk and rework cost.

[0052] In use, the operator places the electric energy meter on the tooling turntable 2, and screws obtained from the nail feeding machine body 6 are screwed on the electric energy meter, the tooling turntable 2 is started, when the in-place detection assembly 4 detects that there is a screw to be tightened on the electric energy meter, the screw locking machine body 3 first tightens the screw, and then the lower table conveying device 5 takes down the electric energy meter and places it on the conveying belt.

[0053] The screw locking machine body 3 and the nail feeding machine body 6 are devices in the art, and those skilled in the art know or should know how to correctly install them.

[0054] As shown in Figure 3 The upper surface of the tooling turntable 2 is provided with four jig stations 21, and the jig station 21 is used to fix the electric energy meter. The setting positions of the four jig stations 21 are as shown in Figure 3 The four jig stations 21 are equidistantly arranged on the upper surface of the tooling turntable 2 along the circumferential array direction.

[0055] The jig station 21 closest to the edge of the base 1 is the upper table station, where the operator can fix the electric energy meter and pre-tighten the screws on the electric energy meter; the jig station 21 below the in-place detection assembly 4 is the detection station, where the in-place detection assembly 4 detects whether there are screws to be tightened on the electric energy meter; the jig station 21 below the screw locking machine body 3 is the locking station, where the screw locking machine body 3 tightens the screws on the electric energy meter; and the jig station 21 below the lower table conveying device 5 is the lower table station, where the lower table conveying device 5 takes away the electric energy meter and sends it to the external conveying mechanism.

[0056] Through the rotation of the tooling turntable 2, the electric energy meter rotates in the order of the upper table station-detection station-locking station-lower table station, and the in-place detection assembly 4, the screw locking machine body 3 and the lower table conveying device 5 complete the work flow.

[0057] By arranging multiple jig stations 21 on the surface of the tooling turntable 2, the electric energy meter can realize the pipeline operation of feeding, detection, locking and discharging. This cyclic indexing mode connects each process in space, greatly shortens the production rhythm of single product, and changes the previous post-checking to pre-checking, avoids the failure of the subsequent locking process, and reduces the rework cost.

[0058] As shown in Figure 3 , 4 The in-place detection assembly 4 includes a detection cylinder 41, a connecting plate 42, a proximity switch 43, an elastic detection rod 44 and a detection jig 45. The detection cylinder 41 is installed on the top of the base 1, the connecting plate 42 is installed on the output end of the detection cylinder 41, the proximity switch 43 is installed on the top of the connecting plate 42, the elastic detection rod 44 is installed on the bottom of the connecting plate 42, and the detection jig 45 is installed on the lower end of the elastic detection rod 44.

[0059] In this embodiment, the detection cylinder 41, the proximity switch 43 and the elastic detection rod 44 are arranged as shown in Figure 3 The elastic detection rod 44 is located directly above the screw of the electric energy meter.

[0060] In use, the detection cylinder 41 is started, the connecting plate 42 is lowered, and the elastic detection rod 44 is moved downward;

[0061] When there is a screw on the electric energy meter, during the preset position of the connecting plate 42, the elastic detection rod 44 will press on the screw cap, and the upper end of the elastic detection rod 44 will enter the detection area of the proximity switch 43, and the proximity switch 43 detects that the elastic detection rod 44 feedbacks that there is a screw.

[0062] When there is no screw on the electric energy meter, the elastic detection rod 44 does not enter the proximity switch 43 in the preset position of the descending connecting plate 42, and the proximity switch 43 has no signal feedback, indicating that there is no screw on the electric energy meter.

[0063] It is worth noting that the stroke amount of the detection cylinder 41 should meet certain requirements. Since the screw is initially screwed on the electric energy meter, the electric energy meter with the screw and the electric energy meter without the screw have different heights at the screw hole position; the stroke amount of the detection cylinder 41 should be such that, when there is no screw on the electric energy meter, the elastic detection rod 44 just stops above the screw hole without contacting the electric energy meter body; and when there is a screw on the electric energy meter, the lower end of the elastic detection rod 44 presses on the screw, and the upper end of the elastic detection rod 44 enters the detection area of the proximity switch 43.

[0066] In the embodiment, the shapes and arrangement positions of the detection seat 441, the detection connecting rod 443, the annular flange 444 and the spring 445 are as shown in Figure 5 The detection connecting rod 443 has a buffering function when contacting the screw, which can ensure accurate detection and avoid damage to the screw or the electric energy meter caused by hard contact. After the detection is completed, if there is a screw on the electric energy meter, the detection connecting rod 443 will enter the detection area of the proximity switch 43 upward and compress the spring 445; then, the detection cylinder 41 drives the detection seat 441 and the detection connecting rod 443 to rise, the spring 445 restores the deformation to make the detection connecting rod 443 reset downward, and there is no detection signal in the proximity switch 43.
