Description

Technical Field

[0001] The present application relates to the technical field of watch processing and positioning devices, and in particular to a watch case processing and positioning device and method. Background Art

[0002] In traditional watch manufacturing, commonly used watch case materials include stainless steel and precious metals. Although stainless steel is widely used, it has the problem of being heavy and may make users feel uncomfortable if worn for a long time; precious metal materials are expensive, which makes the cost of watches high and limits their market popularity. In addition, traditional materials also have certain limitations in performance when dealing with complex environments. For example, they are prone to wear and deformation during high-intensity exercise or when subjected to external force impact.

[0003] With the development of watchmaking technology and the increasing demand of consumers for personalized and high-performance watches, carbon fiber materials have gradually entered the field of watchmaking. Carbon fiber watches refer to watches that use carbon fiber materials to make watch cases, straps and other parts. Carbon fiber is a new type of fiber material with high strength and high modulus fiber with a carbon content of more than 95%. It has many advantages such as lightness, firmness, corrosion resistance and good thermal stability.

[0004] like Figure 1 As shown, the case of a carbon fiber watch generally has a through hole 100 in the middle for installing a watch window in the first step, which is then positioned and fixed by a fixture using the through hole as a reference, and then the end face or hole is processed in the second step to produce corresponding holes 200 and grooves 300, and the grooves are used for installing a crown (the knob on the side of the watch is called a crown or handle).

[0005] Punching and milling operations require a positioning device, and currently most positioning devices use multiple independently set clamps to clamp and fix the watch case. Since each clamp is usually independent of each other, the watch case needs to be initially positioned and then the position of the watch case is firmly fixed by the movement of each clamp in turn during the fixing process. The operation of fixing the watch case is cumbersome and inefficient, so it needs to be improved. Summary of the invention

Then the moving mechanism is operated, and the moving mechanism controls the milling mechanism to move left and right along the X-axis direction and up and down along the Z-axis direction according to the program route. At the same time, the base can move forward and backward along the Y-axis direction, so that the milling mechanism can drill holes in the clamped watch case.

[0011] Preferably, it also includes a cooling pipe, which is arranged on the milling mechanism and is used to transport coolant; wherein a regulating valve is arranged on the cooling pipe and is used to control the output of the coolant.

[0012] By adopting the above technical solution, during the processing, cooling water is transported to the watch case through the cooling pipe, so as to cool the watch case, and the cooling water can also take away the debris on the watch case.

[0014] By adopting the above technical solution, after the holes are processed in the watch case, the second step of processing is required, that is, processing a groove for installing the crown on the outer wall of the watch case. At this time, the watch case can be clamped on each positioning column, and then the positioning plate is pressed on the watch case, and then the positioning plate is pressed on the watch case by a quick clamp, and finally the groove is processed on the watch case by a milling mechanism.

[0035] The present application embodiment discloses a watch case processing positioning device. Figures 2 to 4 The processing positioning device includes a lathe body 1, a base 2, a pneumatic clamp 3, a lever 4, a moving mechanism 5 and a milling mechanism 6. The lathe body 1 is fixedly placed on the ground, and a processing cavity 7 is provided on the lathe body 1, and the processing cavity 7 serves as a place for processing the workpiece. The base 2 is movably arranged in the processing cavity 7, and the base 2 moves forward and backward along the Y-axis direction. The base 2 can be moved by a motor screw or a cylinder drive, which belongs to the existing conventional technical means and is not described here.

[0036] The pneumatic clamp 3 is mounted on the base 2 and is used to clamp the watch case. A positioning groove 8 is provided at the upper end of the pneumatic clamp 3 for placing the watch case. The lever 4 is mounted on the base 2 and connected to the pneumatic clamp 3. The lever 4 is used to control the pneumatic clamp 3 to clamp or release the watch case.

[0037] The moving mechanism 5 is installed above the base 2 and is located in the processing chamber 7; the milling mechanism 6 is installed on the moving mechanism 5 and is used to perform drilling processing on the watch case. The moving mechanism 5 is used to control the milling mechanism 6 to move left and right along the X-axis direction and move up and down along the Z-axis direction. In this embodiment, the moving mechanism 5 includes an X-axis drive mechanism 51 and a Z-axis drive mechanism 52. The X-axis drive mechanism 51 is installed on the lathe body 1, and the Z-axis drive mechanism 52 is movably set on the X-axis drive mechanism 51. The X-axis drive mechanism 51 controls the Z-axis drive mechanism 52 to move left and right along the X-axis direction. The milling mechanism 6 is movably set on the Z-axis drive mechanism 52, and the Z-axis drive mechanism 52 controls the milling mechanism 6 to move up and down along the Z-axis direction. Among them, a cooling pipe 9 is installed on the milling mechanism 6, and the cooling pipe 9 is used to transport coolant. A regulating valve is set on the cooling pipe 9, and the regulating valve is used to control the flow of the cooling pipe 9.

[0038] During processing, the staff first places the watch case in the positioning groove 8, and then controls the pneumatic clamp 3 through the lever 4 to quickly clamp the watch case. Then the moving mechanism 5 is operated, and the moving mechanism 5 controls the milling mechanism 6 to move left and right along the X-axis direction and up and down along the Z-axis direction according to the program route. At the same time, the base 2 can move forward and backward along the Y-axis direction, so that the milling mechanism 6 can drill holes in the clamped watch case. After the processing is completed, the lever 4 is also used to control the pneumatic clamp 3 to release the watch case so that the watch case can be removed. The entire processing process can achieve rapid positioning of the watch case, optimize the production process, and improve processing efficiency. During the processing, cooling water is transported to the watch case through the cooling pipe 9, thereby cooling the watch case. At the same time, the cooling water can also take away the debris on the watch case to ensure the cleanliness of the watch case.

[0039] Specifically, a fixing plate 10, a quick clamp 11, a positioning plate 12 and a positioning column 13 are also installed on the base 2. The fixing plate 10 is located on one side of the pneumatic clamp 3. The positioning columns 13 are fixedly connected to the fixing plate 10, and a plurality of positioning columns 13 are distributed at intervals. As shown in the figure, there are four positioning columns 13, and each positioning column 13 is enclosed to form a rectangular shape. Each positioning column 13 is used for a hole on the watch case, thereby realizing the positioning of the watch case. After the watch case is clamped on each positioning column 13, the positioning plate 12 is clamped on the watch case; the quick clamp 11 is fixedly connected to the fixing plate 10, and is used to press the positioning plate 12 on the fixing plate 10, thereby fixing the position of the watch case.

[0040] After the holes are machined in the watch case, the second step is to machine a groove for installing the crown on the outer wall of the watch case. At this time, the watch case can be clamped on the positioning posts 13, and then the positioning plate 12 is pressed on the watch case, and then the positioning plate 12 is pressed on the watch case by the quick clamp 11, and finally the groove is machined on the watch case by the milling mechanism 6.

[0041] Please refer to Figure 5 and Figure 6 In some embodiments, a connecting column 14 is further installed on the base 2. The connecting column 14 is horizontally arranged, and its two ends are respectively connected to the pneumatic clamp 3 and the fixed plate 10. A driving component 15 and a first ejection component 16 are also installed on the connecting column 14. The first ejection component 16 is used to eject the watch case in the positioning groove 8; the driving component 15 is connected to the first ejection component 16 and is used to control the movement of the first ejection component 16. After the holes in the watch case are machined, it is inconvenient to take out the watch case. By adding the driving component 15 and the first ejection component 16, the driving component 15 can control the first ejection component 16 to eject the watch case, thereby facilitating material removal.

[0042] The first ejection assembly 16 includes a horizontal block 161, a swing rod 162, a lifting block 163 and an ejection block 164. The horizontal block 161 is horizontally movable and arranged in the connecting column 14. One end of the horizontal block 161 is connected to the driving assembly 15, and the other end abuts against the lower end of the swing rod 162. The swing rod 162 is tilted and rotatably connected in the pneumatic clamp 3. The horizontal block 161 is used to control the swing of the swing rod 162; the lifting block 163 is lifted and arranged in the pneumatic clamp 3 and overlaps the upper end of the swing rod 162. Among them, the pneumatic clamp 3 is provided with a guide groove for limiting the up and down movement of the lifting block 163. The swing of the swing rod 162 is used to control the lifting and lowering of the lifting block 163. The ejection block 164 is fixedly connected above the lifting block 163 and is located below the positioning groove 8. The ejection block 164 is used to lift the watch case.

[0043] The driving assembly 15 includes a driving member 151, a pressure block 152 and a first wedge block 153. The first wedge block 153 is horizontally movable and arranged in the connecting column 14. The first wedge block 153 can adopt an existing conventional sliding method, such as the cooperation of a slide slot and a slider. The horizontal block 161 is located between the first wedge block 153 and the swing rod 162. One end of the horizontal block 161 is connected to the first wedge block 153, and the wedge surface of the first wedge block 153 is away from the horizontal block 161. The pressure block 152 is arranged to be lifted and lowered and is connected to the driving member 151. The pressure block 152 is used to control the first wedge block 153 to move horizontally in the direction close to the swing rod 162. The driving member 151 is used to control the pressure block 152 to move up and down. In this embodiment, the driving member 151 is a cylinder or an electric push rod. The first ejection assembly 16 further includes a first return spring 165 , which is sleeved on the outer surface of the horizontal block 161 , and two ends of the first return spring 165 are respectively connected to the first wedge block 153 and the connecting column 14 .

[0044] When it is necessary to lift the watch case on the pneumatic clamp 3, the driving member 151 is first operated. The driving member 151 controls the pressure block 152 to move vertically downward, and the pressure block 152 drives the first wedge block 153 and the horizontal block 161 to move to the right. During the movement of the first wedge block 153 in the direction close to the swing rod 162, the first return spring 165 will be compressed. The end of the horizontal block 161 away from the first wedge block 153 generates a thrust on the swing rod 162, causing the swing rod 162 to swing; the end of the swing rod 162 away from the horizontal block 161 generates a lifting force on the lifting block 163, causing the ejection block 164 to eject the watch case in the positioning groove 8.

[0045] When the pressure of the pressure block 152 on the first wedge block 153 is removed, the lifting block 163 will control the swing rod 162 to swing and reset by its own gravity; at the same time, the first reset spring 165 will control the first wedge block 153 and the horizontal block 161 to automatically reset, so that the watch case can be ejected again later.

[0046] In addition, a second ejector assembly 17 is installed in the connecting column 14. The second ejector assembly 17 is connected to the driving assembly 15 and is used to eject the positioning plate 12. The driving assembly 15 is used to control the horizontal movement of the second ejector assembly 17. After the groove is processed into the watch case, the staff releases the pressing force of the quick clamp 11 on the positioning plate 12, and then uses the driving assembly 15 to control the second ejector assembly 17 to push the positioning plate 12 off the fixing plate 10, so as to facilitate the subsequent separation of the watch case.

[0047] The second ejection assembly 17 includes a second return spring 171 and a push block 172. The driving assembly 15 also includes a second wedge block 154. The second wedge block 154 is movably arranged. The movement mode of the second wedge block 154 is the same as that of the first wedge block 153. The movement paths of the second wedge block 154 and the first wedge block 153 are on the same straight line. The wedge surface of the second wedge block 154 and the wedge surface of the first wedge block 153 are arranged opposite to each other. The pressing block 152 is located between the first wedge block 153 and the second wedge block 154. One end of the push block 172 is connected to the second wedge block 154, and the other end passes through the fixed plate 10 and is used to push out the positioning plate 12. The second return spring 171 is sleeved on the push block 172. The two ends of the second return spring 171 are respectively connected to the second wedge block 154 and the connecting column 14.

[0048] When the positioning plate 12 needs to be unloaded, the driving member 151 controls the pressing block 152 to move downward, and the pressing block 152 drives the second wedge block 154 and the push block 172 to move leftward, and the movement of the push block 172 can push the positioning plate 12 off the fixed plate 10. During the movement of the second wedge block 154, the second return spring 171 will be compressed; when the pressure on the second wedge block 154 is removed, the second return spring 171 will control the second wedge block 154 and the horizontal block 161 to automatically return to their original position, so as to facilitate subsequent ejection.

[0049] The implementation principle of a watch case processing and positioning device in the embodiment of the present application is as follows: during the processing, the staff first places the watch case in the positioning groove 8, and then controls the pneumatic clamp 3 through the lever 4 to achieve rapid clamping of the watch case. Next, the moving mechanism 5 is started, and the moving mechanism 5 can control the milling mechanism 6 to move left and right along the X-axis direction and move up and down along the Z-axis direction according to the preset program route; at the same time, the base 2 can move forward and backward along the Y-axis direction, and such coordinated operation enables the milling mechanism 6 to drill holes on the clamped watch case. After the processing is completed, the pneumatic clamp 3 is controlled again with the help of the lever 4 to loosen the watch case so that the watch case can be removed smoothly.

[0050] After the holes are machined in the watch case, the watch case is clamped on the positioning posts 13, and then the positioning plate 12 is pressed on the watch case, and then the positioning plate 12 is quickly pressed on the watch case by the quick clamp 11, and finally the groove for installing the crown is machined on the watch case by the milling mechanism 6. The whole processing process can realize the rapid positioning of the watch case, optimize the production process, and improve the processing efficiency.

[0051] Based on the above embodiment, the embodiment of the present application further provides a case processing and positioning method, which adopts a case processing and positioning device having all the above structures, comprising the following steps: First, the staff places the watch case to be processed in the positioning groove 8, and then controls the pneumatic clamp 3 to clamp the watch case through the lever 4, and then runs the moving mechanism 5 and the milling mechanism 6. The moving mechanism 5 controls the movement of the milling mechanism 6 according to the route planned by the program, so that the milling mechanism 6 processes four holes on the watch case.

[0052] After the drilling process is completed on the watch case, the staff will accurately clamp the watch case onto the positioning columns 13. Then, the positioning plate 12 is placed steadily and pressed onto the surface of the watch case, and then the quick clamp 11 is used to quickly and firmly fix the positioning plate 12 to the watch case to ensure that the relative position between the two is accurate. After completing the above preparations, the milling mechanism 6 is activated to accurately machine a groove for installing the crown on the watch case according to the pre-set process parameters.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
