In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

This embodiment provides a method for assembling a dial of a pressure gauge movement. As shown in FIG. 1 , an indexing plate 1 is used as a carrying device, and there are six stations on the indexing plate 1, wherein the first station 2 is a machine The core feeding station, the second station 3 is the rivet feeding station, the third station 4 is the first riveting station, the fourth station 5 is the dial 9 feeding station, and the fifth station 6 is the first riveting station. The second riveting station, the sixth station 7 is the blanking station. Among them, in the third station 4 and the fifth station 6, since the riveting operation of the rivet is performed automatically by a mechanical punching device, the personnel injury caused by the riveting operation can be avoided. Actions increase the efficiency of the job.

As shown in Figure 2, the specific operation includes the following steps:

The first step is to load the movement at the first station 2 of the indexing plate 1. By manually feeding the movement, manually place the movement on the fixture of the indexing plate 1, and then step on the foot switch to rotate the indexing plate 1 to the second station 3.

The second step is to load the rivets at the second station 3 of the indexing plate 1 . First, the rivet is transferred to the second station 3 through the vibrating plate 8, and then the suction rod goes down to absorb the rivet, and the rivet is sucked and moved to the top of the rivet hole of the movement, and then the guide plate comes down, and the sucked rivet passes through the guide The plate is introduced into the rivet hole of the movement; the rivet is a double-headed rivet, and the purpose of the guide plate is to prevent the rivet from falling off when it is put in, which can ensure that the rivet enters the rivet hole of the movement.

In the third step, at the third station 4 of the indexing plate 1, the punching connection between the movement and the rivet is performed. One end of the rivet is pressed down by mechanical automatic pressing, so that the rivet and the movement form a riveted connection.

The fourth step is to load the dial 9 at the fourth station 5 of the indexing plate 1 . The dials 9 are stacked on the pusher plate 10 that can move up and down by the dial lifter, and the pusher plate 10 is moved by the lift drive device, so that the dials 9 on the uppermost layer on the pusher plate 10 are sequentially pushed to the designated position. Then, use the vacuum suction cup 11 to grab the dial 9 at the designated position, transfer the dial 9 to the movement, and insert the upwardly protruding rivets on the movement into the rivet holes of the dial 9 .

During the transfer process of the ejector plate 10 , the rising height of the ejector plate 10 is detected by the position detection switch, so as to determine whether there is still a dial 9 on the ejector plate 10 . Specifically, the lifting and lowering driving device adopts a stepping motor 12, and is connected to the pushing plate 10 through the transmission of a gear 13 and a rack 14. The rack 14 is provided with a limit plate for triggering a position detection switch. Gold, when the ejector plate 10 rises to the highest position and the lowest position, the position detection switches are triggered, and then control the lift drive device to drive forward or reverse, so that the ejector plate 10 is between the highest position and the lowest position. With accurate movement, when the ejector plate 10 is at the lowest position, it is convenient for the dial 9 to be loaded.

In the fifth step, at the fifth station 6 of the indexing plate 1, the punching connection between the dial 9 and the rivet is performed. The upper end of the rivet is pressed down by mechanical pressing, so that the rivet and the dial 9 form a riveted connection, so that the dial 9 and the movement are fixedly connected.

In the sixth step, at the sixth station 7 of the indexing plate 1, the finished product is blanked. The assembled pressure gauge can be removed, or the assembled pressure gauge can be removed at the first station 2 of the indexing plate 1 during material loading.

Structurally, as shown in FIG. 1 , at the rivet feeding station, there is a rivet feeding machine, and the inlet of the rivet feeding machine is connected to the vibrating plate 8 , and the rivets conveyed in the vibrating plate 8 pass through The suction rod of the rivet feeding machine is grabbed above the rivet hole of the movement, and then the rivet is introduced into the rivet hole of the movement through the guide plate.

As shown in FIG. 2 , at the third station 4 and the fifth station 6 , the rivets are riveted by means of mechanical compression, respectively. Among them, at the third station 4, the lower half of the rivet is riveted first, so that the rivet presses the movement, and then at the fifth station 6, the rivet is riveted by mechanically rotating and pressing down, so that the rivet can be riveted. The upper end is crimped to press the dial 9 tightly, and thus a product is assembled.

As shown in FIG. 3 , it is a dial feeding device for transferring the dial 9 to be assembled to the movement. The dial feeding device includes a dial lift and a transfer device.

The dial lifter has a pusher plate 10 that can move up and down for stacking the dials 9, and the dial 9 on the uppermost layer on the pusher plate 10 is suitable for being transferred to the movement by a transfer device. Specifically, the dial lifter includes: a push plate 10, a lift drive device, and a position detection switch. Wherein, the lifting driving device adopts a stepping motor 12, and is connected with the pushing plate 10 through the transmission of the gear 13 and the rack 14, so as to drive the pushing plate 10 to move upward in a stepwise manner; the The position detection switch is used to detect the rising height and the falling height of the pushing plate 10 , and a photoelectric sensor switch 15 may be used as a specific position detection switch.

The transfer device is used for grabbing a dial 9 on the pusher 10 and then transferring the dial 9 to the movement. Specifically, the transfer device uses a vacuum suction cup 11 to grab the dial 9 on the dial lifter. It will move up a distance of the thickness of the dial 9, so that the vacuum suction cup 11 is always kept in the same position for the operation of sucking the dial 9. After the dial 9 on the entire ejector plate 10 is all taken out, it will be separated from the ejector plate. The gap of the limit sheet metal connected to 10 reaches the detection position of the photoelectric sensor. At this time, the pusher plate 10 returns to its position, and the whole machine stops running. After the worker places the dial 9 on the pusher plate 10, press the start button again. button to start working.

Obviously, the above-mentioned embodiments are only examples for clear description, and are not intended to limit the implementation manner. For those of ordinary skill in the art, changes or modifications in other different forms can also be made on the basis of the above description. There is no need and cannot be exhaustive of all implementations here. However, the obvious changes or changes derived therefrom still fall within the protection scope of the present invention.
