Description

Technical Field

[0001] The utility model relates to the technical field of main plate processing, and particularly relates to a fixture for processing a main plate of a watch. Background Art

[0002] Most of the main plates of watches are circular and are used to provide main support when installed inside the main plate. A plurality of installation grooves and through holes are distributed thereon for installing various components of the watch, such as watch hands, each transmission wheel, and the shafts for transmission, etc.

[0003] When processing the installation grooves of the main plate of a watch, it is necessary to clamp the main plate and fix the main plate on the fixture to prevent displacement during the processing of the main plate, thereby preventing processing errors. The existing fixture clamping methods are divided into two categories; the first category is glue sticking. During clamping, the back surface of the main plate and the fixture are covered with glue, and then the back surface of the main plate is adhered to the fixture through the glue to fix it. Such a clamping method is slow, has a low qualified rate, and it is also difficult to clean the glue on the main plate after processing, and it also brings great difficulties to the electroplating appearance of the main plate in the later stage; the second category is a threaded gland. During clamping, the main plate is placed on the fixture, the cover plate is covered on the main plate, and is connected by threads to fix the main plate. Compared with the glue sticking solution, the installation speed is slightly improved. When rotating the cover plate, the cover plate will contact the surface of the main plate, thereby generating friction and easily causing scratches on the surface of the main plate, which also brings great difficulties to the appearance repair in the later stage. Summary of the Utility Model

[0004] To solve the above problems, that is, to reduce the scratches caused on the main plate during clamping, the utility model provides a fixture for processing a main plate of a watch, which includes a base. A top cover is installed at the top end of the base. A fixing hole for fixing the main plate is opened in the top cover. A communication cavity is opened in the base. One end of the communication cavity is installed with a suction cup. The suction cup is arranged in the fixing hole, and its large-diameter end faces upward; the other end of the communication cavity is used to communicate with a vacuum pump.

[0005] The further setting of the utility model is: an upper eaves is arranged on the upper surface of the top cover. The upper eaves is arranged along the circumference of the top cover and is coaxially arranged with the fixing hole. A notch is opened on the upper eaves. A blowing port corresponding to the notch is opened on the upper eaves. The blowing port is used to communicate with a hair dryer.

[0006] The further setting of the utility model is: the blowing port is arranged in a flared shape.

[0007] The further setting of the utility model is: a baffle is rotatably connected to the upper eaves. The baffle is arranged on the side of the notch away from the blowing port.

[0008] A further setting of the present utility model is that a positioning post is integrally provided at the top end of the base, the fixing hole is sleeved on the positioning post, and one end with a small diameter of the suction cup is fixedly connected to the positioning post.

[0009] A further setting of the present utility model is that a lower eaves is provided on the lower surface of the top cover, and the lower eaves is threadedly connected to the base.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. Through the cooperation of the vacuum pump and the suction cup, the adsorption of the main clamp can be realized. Then, through the limitation of the through hole, the purpose of stably limiting the main clamp can be achieved. And the vacuum adsorption can effectively reduce the hard contact generated during the clamping of the main clamp, thereby reducing the scratches caused during the clamping of the main clamp.

[0012] 2. Through the cooperation of the blower and the air outlet, the purpose of timely blowing out the chips generated during the processing of the main clamp can be achieved, thereby avoiding the problem that the chips will cause secondary damage to the main clamp. At the same time, by setting the baffle, the problem that the chips will splash onto the personnel when being blown out can be avoided.

[0013] 3. By using the threaded connection between the lower eaves and the base, the problem of adjusting the up and down height of the top cover can be realized, and further the purpose of adjusting the distance between the top end of the fixing hole and the top end of the positioning post can be achieved, that is, by changing the distance between the two, the purpose of clamping main clamps with different thicknesses can be achieved, making the applicability of the present device stronger.

[0019] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0020] The utility model proposes a fixture for processing a main plate of a watch, comprising a base 1, a top cover 2 is installed on the top of the base 1, a fixing hole 21 for fixing the main plate is opened in the top cover 2, the fixing hole 21 is a through hole, a connecting cavity 11 is opened in the base 1, one end of the connecting cavity 11 is connected to a suction cup 3, and the other end of the connecting cavity 11 is used to connect to a vacuum pump.

[0021] The end with a small diameter of the suction cup 3 is connected to the connecting cavity 11, and the end with a large diameter of the suction cup 3 is set upward. The suction cup 3 is set in the fixing hole 21, that is, through the cooperation of the vacuum pump and the suction cup 3, the purpose of adsorbing the main splint in the fixing hole 21 can be achieved, thereby achieving the longitudinal limiting and fixing effect on the main splint, and in combination with the lateral limiting of the fixing hole 21, the stable clamping and limiting of the main splint can be achieved.

[0022] An upper eave 22 is integrally provided on the upper surface of the top cover 2. The upper eave 22 is coaxially arranged with the fixing hole 21, and is arranged along the circumference of the top cover 2. The diameter of the upper eave 22 is larger than the diameter of the fixing hole 21. A notch is provided on the upper eave 22, and a blowing port 221 is provided on the upper eave 22 opposite to the notch. The blowing port 221 is used to connect with a hair dryer, so that the hair dryer can blow air to the upper surface of the top cover 2 through the blowing port 221. That is, when processing is performed, the wind blown out of the blowing port 221 can blow the chips generated by processing the main plate out of the notch, thereby preventing the chips from damaging the main plate or affecting the processing.

[0023] The air outlet 221 is configured to be trumpet-shaped, and the larger end of the air outlet 221 is configured to face the main plate, so that the wind from the air outlet 221 is blown toward the chips in a divergent manner, thereby allowing the chips to be blown out more comprehensively.

[0024] The upper eave 22 is also rotatably connected with a baffle 222, which is arranged on the side of the notch away from the air outlet 221. The baffle 222 can prevent the chips from splashing everywhere when being blown out, thereby preventing the splashing chips from scratching people.

[0025] A positioning column 12 is integrated at the top of the base 1. The positioning column 12 is adapted to the fixing hole 21, and the fixing hole 21 is coaxially sleeved on the positioning column 12. The small diameter end of the suction cup 3 is fixedly connected to the top of the positioning column 12, and the connecting cavity 11 passes through the positioning column 12 and is connected to the suction cup 3.

[0026] The lower surface of the top cover 2 is integrally provided with a lower eave 23, which is coaxially arranged with the top cover 2. The lower eave 23 is provided with an internal thread, and the outer wall of the base 1 is provided with an external thread that matches the internal thread, so that the lower eave 23 and the base 1 are threadedly connected via the internal thread and the external thread.

[0027] That is, when the top cover 2 is rotated, the top cover 2 can move up and down. Further, when the top cover 2 moves up and down, the distance between the top end of the fixing hole 21 and the top end of the positioning column 12 will change accordingly. That is, by changing the distance between the two, the purpose of clamping main splints of different thicknesses can be achieved, making the applicability of this device stronger.

[0028] It should be noted that when the top cover 2 is rotated, the connection between the air outlet 221 and the hair dryer needs to be disconnected. After adjusting the position of the top cover 2, the hair dryer and the air outlet 221 are then connected.

[0029] It should also be noted that when using this application to clamp the main splint, it needs to be carried out before the drilling process. That is, the fixture disclosed in this application is only applicable to clamping the non-drilled main splint and is applied to the process of milling the installation groove.

[0030] In summary, through the cooperation of the vacuum pump and the suction cup 3, the adsorption of the main splint can be realized, and through the limitation of the through hole, the purpose of stably limiting the main splint can be achieved. And vacuum adsorption can effectively reduce the hard contact generated when clamping the main splint, thereby reducing the scratches caused when clamping the main splint. Through the cooperation of the blower and the air outlet 221, the purpose of timely blowing out the chips generated during the processing of the main splint can be achieved, thereby avoiding the problem that the chips will cause secondary damage to the main splint. At the same time, by setting the baffle 222, the problem that the chips will splash onto the personnel when being blown out can be avoided. By using the threaded connection between the lower eaves 23 and the base 1, the problem of adjusting the up and down height of the top cover 2 can be achieved, and further the purpose of adjusting the distance between the top end of the fixing hole 21 and the top end of the positioning column 12 can be achieved. That is, by changing the distance between the two, the purpose of clamping main splints of different thicknesses can be achieved, making the applicability of this device stronger.
