Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary watch preparation, in particular to a positioning tool for an auricle-shaped watch connector. Background Art

[0002] When a watch is worn, it needs to be connected to the watchband through the watch connector and the watch pin, and then worn according to the hand, position, and tightness of the watchband. At present, some of the connectors used to connect to the watchband on watches, especially the connectors of electronic watches, are independently prepared, and are no longer integrated on the watchcase like traditional mechanical watches. The structure of the independently prepared connector is mostly ear-shaped:

[0003] For example, the fixing part of the "wearable smart device" disclosed in the Chinese invention application with publication number CN117996398A is fixedly arranged on the housing of the wearable smart device, and can be fixed by screws or buckles, and the end of the fixing part is connected to the end of the strap. The fixing part includes a first connecting arm and a second connecting arm. One end of the first connecting arm is fixedly connected to the housing, and the other end of the first connecting arm is fixedly connected to the second connecting arm. The opposite ends of the second connecting arm are respectively provided with a second mounting part, and the second mounting part is detachably connected to the strap. Specifically, the strap usually has an ear rod (watch bolt) that can be inserted into the hole corresponding to the mounting part.

[0004] Or the shape design of the “watch strap connector” as shown in the Chinese design publication number CN308583764S.

[0005] After the ear-shaped watch strap connector is prepared and formed, it is also necessary to use a CNC gong machine to process the part with the watch bolt hole to make it more in line with the standard. The current fixing tooling for the watch strap connector used in this process is relatively simple, and workers mainly use hand-cranked clamps to manually clamp and loosen them, which is not convenient to use.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 , a positioning tool for processing a bolt hole of an auricle-shaped watch connector. The auricle-shaped watch connector 1 includes a C-shaped main body 11 (similar to the helix of the auricle) and bolt holes 12 located at both ends of the main body 1. The positioning tool 2 is used to position the main body 11 of the auricle-shaped watch connector, and make the end 111 with the bolt hole exposed outside the positioning tool 2, so as to be used for positioning the main body for CNC gong, polishing and other processes on the part with the bolt hole.

[0031] In this embodiment, the positioning tool 2 includes a mounting seat 21. The mounting seat 21 can be connected to the support platform of the CNC machine tool or other workbench through connecting parts such as screws and bolts, and the mounting seat 21 has corresponding mounting holes.

[0032] The mounting seat 21 is connected with a positioning seat 22, which is located on the top side of the mounting seat 21. The positioning seat 22 can be connected to the mounting seat 21 by connecting members such as screws and bolts; it can be that a screw hole is set on the positioning seat 22, a mounting hole is set on the mounting seat 21, and then connected by configured screws.

[0033] A first positioning groove 221 is formed on the left side surface of the positioning seat 22. The first positioning groove 221 is arranged in a C shape and an end connecting port 222 is formed on the front side surface of the positioning seat 22 to be suitable for placing a part of the main body 11 of the auricle-shaped watch connector. The two ends of the auricle-shaped watch connector pass through the positioning seat 22 through the end connecting port 22 so that the end 111 with the watch bolt hole is located in front of the positioning seat 22.

[0034] A connecting seat 23 is provided on the left side of the positioning seat 22, and a second positioning groove 231 corresponding to the first positioning groove 221 is formed on the right side surface of the connecting seat 23. The second positioning groove 231 is arranged in a C shape and an end connecting port is formed on the front side surface of the connecting seat 23. When the connecting seat 23 is close to the positioning seat 22 from left to right, the first positioning groove 221 and the second positioning groove 231 are combined to accommodate the main body 11 of the auricle-shaped watch connector, and form a positioning, holding and clamping of the main body 11 of the auricle-shaped watch connector.

[0035] The left side surface of the positioning seat 22 has a positioning portion formed by the first positioning groove 221 and the left side front edge 223 of the positioning seat, wherein the positioning portion extends to the left beyond the first positioning groove 221 to form a positioning guide column 224; the right side surface of the connecting seat 23 is formed with a coupling groove 232 corresponding to the positioning guide column 224.

[0036] like Figure 2 , 3 As shown, after the connecting seat 23 moves away from the positioning seat 22 to the left, the C-shaped opening 115 of the auricle-shaped watch connector can be oriented forward and sleeved on the positioning guide column 224 from left to right, and finally slide along the positioning guide column 224 to the first positioning groove 221.

[0037] When the C-shaped opening 115 of the auricle-shaped watch connector faces forward, the positioning guide column 224 has an upper positioning portion 2241 corresponding to most of the upper arc-shaped portion 112 of the main body of the auricle-shaped watch connector, a lower positioning portion 2242 corresponding to most of the lower arc-shaped portion 113 of the main body of the auricle-shaped watch connector, and a rear positioning portion 2243 corresponding to all of the rear arc-shaped portion 114 of the main body of the auricle-shaped watch connector. The upper positioning portion 2241, the lower positioning portion 2242 and the rear positioning portion 2243 form positioning in three different directions, so that the main body 11 of the auricle-shaped watch connector will not rotate in the up-down direction on the positioning guide column 224, and is limited to sliding in the left-right direction. That is, when the main body 11 of the auricle-shaped watch connector (with the C-shaped opening facing forward) is sleeved on the positioning guide column 224 and the connecting seat 23 is brought close to the positioning seat 22 from left to right, the main body 11 of the auricle-shaped watch connector is pushed by the connecting seat 23 and enters the first positioning groove 221. At the same time, due to the proximity of the connecting seat 23, the main body 11 of the auricle-shaped watch connector also enters the second positioning groove 231.

[0038] The setting of the positioning guide column 224 forms a pre-positioning structure of the main body 11 of the auricle-shaped watch connector, so that the user does not need to hold the auricle-shaped watch connector all the time to keep it on the first positioning groove 221 before clamping the main body 11 of the auricle-shaped watch connector, which effectively avoids pinching of the hand during clamping.

[0039] A linear electric drive assembly 24 is provided between the positioning seat 22 and the connecting seat 23 to make the connecting seat 23 close to / away from the positioning seat 22 in the left and right direction. After the positioning guide column 224 pre-positions the main body 11 of the auricle-shaped watch connector, the linear electric drive assembly 24 drives the clamping, and the positioning, holding and clamping are more convenient.

[0040] The linear electric control drive assembly 24 includes a drive cylinder 241 and a guide rod 242 mounted on the positioning seat 22. A guide hole 243 is formed on the connecting seat 23 to match the guide rod 242. The piston rod of the drive cylinder 241 extends to the left and is connected to the connecting seat 23. The drive cylinder 241 drives the connecting seat 23 to the left away from the positioning seat 22, and drives the connecting seat 23 to the right close to the positioning seat 22.

[0041] When the driving cylinder 241 drives the connecting seat 23 to the left away from the positioning seat 22 to a preset far point, the distance satisfies: the positioning guide column 224 is separated from the engagement groove 232 (or expressed as the positioning guide column and the connecting seat are separated), so that the gap between the positioning guide column 224 and the right side surface of the connecting seat 23 is larger than the left and right width of the main body 11 of the auricle-shaped watch connector, that is, the main body 11 of the auricle-shaped watch connector can be mounted on the positioning guide column 224 through the gap between the positioning guide column 224 and the right side surface of the connecting seat 23.

[0042] The left-right width L1 of the gap is usually 1 cm to 7 cm larger than the left-right width L2 of the main body of the auricle-shaped watch connector.

[0043] like Figure 3 As shown, the positioning guide column 224 is located in front of the guide rod 242. A positioning block 225 extending to the left is also formed on the left side of the positioning seat 22, and a positioning groove 233 corresponding to the positioning block 225 is formed on the right side of the connecting seat 23. The positioning block 225 is located behind the guide rod 242. On the one hand, the positioning guide column 224 and the positioning block 225 can form a positioning pin-like member when the connecting seat 23 is close to the positioning seat 22, so that the connecting seat 23 is more accurate when it is close. On the other hand, the positioning guide column 224 and the positioning block 225 can form a force support on the front and back sides of the guide rod 242. When the end 111 of the auricle-shaped watch connector is applied with force, it can better prevent the connecting seat 23 from swinging left and right, which may cause the clamping of the auricle-shaped watch connector to loosen, and the structure is more stable.

[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
