Description
Technical Field
[0001] The utility model relates to the technical field of watch processing, in particular to a fixture for drilling holes in a watch case. Background Art
[0002] A watch is a portable timekeeping device that is carried or worn by a person. When a watch is processed, holes are usually opened on the back of the watch for screws to pass through. The back of the watch can be firmly installed on the back of the watch through screws, and the back of the watch can protect the parts inside the watch, and when a sealing ring is installed, the watch can have a certain waterproof function.
[0003] However, when drilling a hole in the back case of a watch, due to the thin thickness of the case, if the case is not effectively positioned, the hole opening position of the back case of the watch will be deformed. At the same time, when drilling a hole in the back case of the watch, the high temperature generated during drilling may cause the back case of the watch to deform, which not only affects the appearance of the product but also affects the sealing of the watch. Therefore, a jig for drilling holes in watch cases is proposed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a jig for drilling holes in a watch case, which has the advantages of positioning the back case of the watch and reducing the temperature during drilling, thereby solving the problems of hole deformation caused by inaccurate positioning when drilling the back case of the watch and deformation of the case caused by high temperature during drilling.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a jig for drilling holes in a watch case, comprising a base, a placement groove is provided in the middle of the upper surface of the base, a filling groove is provided at the front end of the base, and a material withdrawal groove is provided at the rear end of the base, the placement groove, the filling groove and the material withdrawal groove are interconnected and the bottoms are flat, and also includes a limiting plate;
[0006] The limiting plate is movably placed in the placement slot;
[0007] Among them, a cooling chamber is fixedly installed on the upper surface of the limit plate;
[0008] Among them, holes are opened on both sides of the cooling chamber and connecting pipes are installed in communication.
[0009] When using a jig for drilling holes in a watch case in the technical solution, place the case blank in the loading slot to ensure that it is located directly below the placement slot. The cross-sectional dimensions of the case blank should match those of the limiting plate to ensure precise positioning. Place the limiting plate in the placement slot and use the limiting holes on the upper surface of the limiting plate to locate the position of the hole to be opened on the case blank. At the same time, the limiting holes match the positions of the chip removal holes. A push plate is movably inserted in the material withdrawal slot. A connecting plate is fixedly installed at one end of the push plate away from the base. A cooling chamber is installed on the upper surface of the limiting plate. Holes are opened on both sides and connected with connecting pipes. Both ends of the two connecting pipes are connected to the refrigeration mechanism respectively. The connection can deliver cold air to the cooling chamber through the connecting pipe, and the cold air circulates with the help of the refrigerator, so as to reduce the temperature of the watch case blank during the drilling process and reduce thermal deformation. After ensuring that the watch case blank is stably positioned by the limit plate, the drilling operation is carried out. During the drilling process, the drill bit is inserted through the limit hole and the drilling operation is carried out. At the same time, the cold air generated by the refrigerator continuously cools the watch case blank through the cooling chamber to reduce the influence of the high temperature generated by drilling on the watch case blank. The metal chips generated by drilling are discharged through the chip removal holes. The chip removal holes are located at the four corners of the bottom of the placement slot to ensure smooth chip removal. After the drilling is completed, the push plate slides in the material withdrawal slot to push the watch case blank out of the loading slot.
[0010] Preferably, the lower surface of the base is provided with chip removal holes, and the chip removal holes are located at the four corners of the bottom of the placement groove.
[0011] Chip removal holes are designed on the lower surface of the base to ensure that metal chips generated during the drilling process can be discharged smoothly and effectively prevent metal chips from accumulating, reducing damage to drilling equipment and case blanks and improving processing efficiency and quality.
[0012] Preferably, a watch case blank is movably inserted into the loading slot, the watch case blank is located directly below the placement slot, and the cross-sectional dimensions of the watch case blank match the cross-sectional dimensions of the limiting plate.
[0013] Ensure that the size of the case blank matches the limit plate, so as to achieve precise positioning, reduce errors in the drilling process, and improve the drilling accuracy and processing quality of the case blank.
[0014] Preferably, a push plate is movably inserted in the material withdrawal groove, and a connecting plate is fixedly installed at one end of the push plate facing away from the base.
[0015] The cooperation between the push plate and the connecting plate realizes the flexible movement of the push plate. After the drilling is completed, the processed watch case blank can be pushed out through the push plate, which is convenient for subsequent operation and processing.
[0016] Preferably, a connecting spring is elastically mounted on the connecting plate, one end of the connecting spring facing away from the connecting plate is elastically connected to the base, and the connecting spring adopts a compression spring structure design.
[0017] The elastic design of the connecting spring allows the push plate to be away from the filling slot when no force is applied, ensuring that the push plate can push the watch case blank out after the drilling is completed, and can automatically reset after the watch case blank is pushed out.
[0018] Preferably, limiting holes are respectively provided at the four corners of the upper surface of the limiting plate, and the lower surface of the limiting plate is in contact with the upper surface of the watch case blank but is not fixedly connected.
[0019] The design of the limit hole realizes the positioning of the limit plate and the hole opening position of the watch case blank, and provides stable clamping of the watch case blank through the limit plate during the drilling process to prevent the watch case blank from moving or deforming, thereby ensuring the accuracy of drilling.
[0020] Preferably, the position-limiting hole matches the position of the chip removal hole, and the diameter of the position-limiting hole is smaller than the diameter of the chip removal hole.
[0021] The precise matching of the limiting holes and the chip removal holes ensures that the metal chips in the drilling process can be discharged smoothly, thereby reducing the accumulation of metal chips in the drilling process and improving the cleanliness and processing efficiency of the drilling.
[0022] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0023] The utility model provides a placement groove in the middle of the upper surface of the base for placing the watch back case, and the placement groove is connected with the loading groove at the front end of the base and the material withdrawal groove at the rear end to form a smooth processing path. The limit plate is movably placed in the placement groove, and a cooling bin is fixedly installed on the upper surface of the limit plate. The setting of the limit plate ensures the stability and accuracy of the watch case blank during the drilling process. The cooling bin on the limit plate is connected to the external cooling system through the connecting pipes on both sides to form a cold air circulation system. The connecting pipe transports cold air to the cooling bin, which effectively reduces the temperature of the watch case blank during the drilling process and reduces the risk of thermal deformation. By setting the limit plate, the case blank can be stably positioned in the placement groove during the drilling process, avoiding the problem of hole deformation caused by inaccurate positioning. At the same time, the setting of the cooling chamber and the connecting pipe allows the case blank to be continuously cooled during the drilling process, effectively reducing the case deformation problem caused by high temperature, improving the processing accuracy and the aesthetics of the case, and the design of the interconnected loading groove and withdrawal groove makes the filling and withdrawal process of the case blank smoother, reducing the processing time, improving production efficiency, and achieving the effect of positioning the back case of the watch and reducing the temperature during drilling.
