Pneumatic pressurization is used, and the pressure is stable, making the seal between the glass top plate and the watch case tighter. At the same time, this pneumatic press for watch glass operates automatically, greatly increasing the pressing efficiency of the glass top plate and improving the pressing quality of the glass top plate.

[0004] During the use of the above device, the watch case needs to be installed on the base. This process requires manual installation and fixation by workers. During installation, the watch case also needs to be aligned with the base to prevent deviation during pressing. The installation and alignment process is time-consuming and laborious. Content of the Utility Model

[0005] The purpose of the utility model is to provide a circular clock case crimping device with automatic alignment to solve the problem of time-consuming and laborious installation and alignment process proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A circular clock case crimping device with automatic alignment, which includes a support platform placed horizontally on a table, and a corresponding mounting frame is fixedly installed above the support platform. It also includes:

[0007] A vertically distributed telescopic cylinder is fixedly installed at the middle position of the mounting frame, and a circularly structured crimping die is fixedly installed at the bottom end of the telescopic cylinder;

[0008] A square-structured bearing plate is installed inside the groove on the upper surface of the support platform, and a clock case to be pressed and assembled is placed above the bearing plate. And a clamping block for fixing the clock case is installed above the bearing plate, and an automatic alignment mechanism is arranged below the clamping block.

[0009] Preferably, a first lead screw is rotatably installed inside the support platform and is threadedly connected through the bearing plate, and the first lead screw is driven to rotate by a driving motor fixedly installed inside the rear end of the support platform.

[0010] Preferably, the automatic alignment mechanism includes a moving slider fixedly installed on the lower surface of the clamping block, and the moving slider and a limiting chute opened on the upper surface of the bearing plate form a left-right sliding structure.

[0011] Preferably, a second lead screw rotatably connected to the bearing plate is installed through the thread inside the moving slider, and the outer part of the second lead screw is provided with a thread structure with two opposite directions.

[0012] Preferably, a transmission gear located outside the bearing plate is coaxially and fixedly installed at the left end of the second lead screw, and the transmission gear and a fixed rack fixedly installed on the upper surface of the support platform form an intermeshing structure.

[0013] Preferably, a cleaning spray head is fixedly installed on the upper surface of the clamping block, and the cleaning spray head and an air bag fixedly installed inside the support platform form a communicating structure through a connecting hose, and the air bag and the bearing plate are corresponding to each other in the front and rear positions.

[0014] Preferably, a buffer plate made of sponge material is installed outside the side surface of the clamping block, and a connecting spring is fixedly installed between the buffer plate and the clamping block.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The circular clock case crimping device with automatic alignment adopts a novel structural design, and the specific content is as follows:

[0016] 1. The bearing plate is used to place the clock case. During the placement process, the driving motor is started to drive the first lead screw to rotate. The bearing plate threadedly installed outside the first lead screw is driven to move forward by the first lead screw, so as to move the bearing plate to the outside, which is convenient for the staff to place the clock case.

[0017] Furthermore, during the movement of the bearing plate, the transmission gear rotatably installed on its side is synchronously moved. Since the transmission gear is meshed with the fixed rack, the transmission gear drives the second lead screw to rotate by means of the meshing connection between the two. During the rotation of the second lead screw, the moving slider threadedly installed outside it drives the clamping block to move, so that the clamping block clamps the clock case, and the automatic alignment is realized by using the inclined structure of the clamping block.

[0018] Furthermore, during the process of the clamping block clamping the clock case, the buffer plate on the side surface of the clamping block is extruded by the clock case. At this time, the clamping block extrudes the connecting spring, and the compression amount of the buffer spring enables the clamping block to adapt to clock cases of different sizes.

[0019] 2. When the carrier plate is retracted into the support platform, the carrier plate is used to squeeze the air injection airbag. When the airbag is squeezed, the air inside it is ejected from the cleaning nozzle through the connecting hose, so as to blow out some sundries that may have fallen into the clock housing by means of air flow.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 6, in order to solve the problem that the traditional device is not convenient for placing the clock housing 6, the following technical solution is provided, and specifically disclosed: including a support platform 1 horizontally placed on the desktop, a corresponding mounting frame 2 is fixedly installed above the support platform 1, a vertically distributed telescopic cylinder 3 is fixedly installed at the middle position of the mounting frame 2, and a circular pressing die 4 is fixedly installed at the bottom end of the telescopic cylinder 3. A square-shaped bearing plate 5 is installed inside the groove on the upper surface of the support platform 1, and a clock housing 6 to be press-fitted and assembled is placed above the bearing plate 5. A first lead screw 10 that is rotationally installed inside the support platform 1 and threadedly connected through the bearing plate 5 is installed, and the first lead screw 10 is driven to rotate by a drive motor 11 fixedly installed inside the rear end of the support platform 1.

[0030] When using the device, first turn on the drive motor 11, use the drive motor 11 to drive the first lead screw 10 to rotate. During the rotation of the first lead screw 10, the bearing plate 5 threadedly installed outside it is driven to move forward, so as to move the bearing plate 5 to the outside, facilitating the staff to place the clock housing 6 above the bearing plate 5.

[0031] Embodiment Two: Please refer to Figures 3 - 5 and Figure 7 , in order to solve the problem that the traditional device is not convenient for aligning and centering the clock housing 6, the following technical solution is provided. An automatic centering mechanism is set up to automatically push the clock housing 6 to the middle position during the process of clamping the clock housing 6. Specifically disclosed: a clamping block 7 for fixing the clock housing 6 is installed above the bearing plate 5, and an automatic centering mechanism is arranged below the clamping block 7. The automatic centering mechanism includes a moving slider 8 fixedly installed on the lower surface of the clamping block 7, and the moving slider 8 and a limit chute 9 opened on the upper surface of the bearing plate 5 form a left-right sliding structure. A second lead screw 12 that is rotationally connected to the bearing plate 5 and threadedly installed through the moving slider 8 is installed inside the moving slider 8, and the outer part of the second lead screw 12 is provided with two threaded structures with opposite directions. A transmission gear 13 located outside the bearing plate 5 is coaxially fixedly installed at the left end of the second lead screw 12, and the transmission gear 13 and a fixed rack 14 fixedly installed on the upper surface of the support platform 1 form an intermeshing structure. A buffer plate 18 made of sponge material is installed outside the side surface of the clamping block 7, and a connecting spring 19 is fixedly installed between the buffer plate 18 and the clamping block 7.

[0032] The clock housing 6 is placed between the left and right clamping blocks 7. Then, the driving motor 11 drives the first lead screw 10 to rotate in the reverse direction, and the load-bearing plate 5 is retracted to the inside of the support platform 1 by using the first lead screw 10. At this time, the transmission gear 13 drives the second lead screw 12 to rotate due to the meshing between the transmission gear 13 and the fixed rack 14. During the rotation of the second lead screw 12, the moving slider 8 threadedly installed outside it slides inside the limit chute 9, and the clamping block 7 is driven to move synchronously by using the moving slider 8, so that the clamping block 7 moves towards the middle to clamp the clock housing 6. At the same time, the inclined structure of the clamping block 7 automatically pushes the clock housing 6 to the middle position to achieve automatic alignment. Moreover, the reaction force of the clock housing 6 squeezes the buffer plate 18, and the buffer plate 18 squeezes the connecting spring 19. The distance between the clamping blocks 7 can be adjusted by using the compression amount of the connecting spring 19, so as to adapt to clock housings 6 of different sizes.
