Description

Technical Field

[0001] This utility model relates to the field of production equipment technology, and in particular to a knob assembly fixture and watch production equipment. Background Technology

[0002] A wristwatch is a portable timepiece worn on the wrist. Wristwatches are generally categorized into mechanical watches, electronic watches, and smartwatches. A crown, or knob, is typically mounted on the watch case for adjustment or calibration. The case is usually ring-shaped, with mounting holes perpendicular to the watch's thickness. The crown is installed within these holes, and currently, the case is primarily held in place by a clamp, which then presses the crown into the mounting hole.

[0003] Because watches are relatively thin and most watch cases have a curved outer ring, the mounting surface of the knob is small and uneven, making it difficult to accurately position the mounting surface. The mounting surface of the knob is prone to misalignment, causing the pressure applied by the operator during installation to intersect with the axis of the mounting hole. This not only increases the difficulty of knob installation and affects production efficiency, but also easily damages the case and / or the knob, resulting in significant production losses. Utility Model Content

[0004] The purpose of this utility model is to provide a knob assembly fixture and watch production equipment to accurately position the outer casing and ensure that the pressure applied to the knob during installation coincides with the axial direction of the mounting hole, thereby improving the convenience of knob installation, increasing production efficiency, and reducing production losses.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A knob assembly fixture for positioning a housing, wherein the housing has mounting holes, and the knob assembly fixture includes:

[0007] Positioning seat;

[0008] A positioning component, disposed on one side of the positioning seat, the positioning component being capable of positioning the housing; and,

[0009] A cover is positioned and placed on the side of the positioning seat near the positioning component. The inner wall of the cover can abut against the outer shell. A positioning through hole is formed on the cover along the axial direction of the mounting hole at the position corresponding to the mounting hole.

[0010] Preferably, the positioning component includes:

[0011] A first positioning element and a second positioning element are provided at intervals and the distance between them is adjustable. The opposite sides of the first positioning element and the second positioning element can abut against the inner ring of the outer shell.

[0012] Preferably, the positioning seat is provided with a sliding groove, and the second positioning member is slidably disposed inside the sliding groove along the distribution direction of the first positioning member and the second positioning member.

[0013] Preferably, the positioning seat has a driving waist hole along the sliding direction of the second positioning member, and the second positioning member has a plug hole communicating with the driving waist hole.

[0014] Preferably, an elastic element is provided between the second positioning element and the first positioning element, and the elastic element is in a compressed state when the opposite sides of the first positioning element and the second positioning element abut against the outer shell.

[0015] Preferably, a limiting cover is provided on one side of the positioning seat, and the limiting cover covers part of the opening of the sliding groove.

[0016] Preferably, the cover includes:

[0017] A positioning ring, fitted onto the outside of the positioning assembly, wherein the inner ring of the positioning ring is capable of positioning the outer shell; and,

[0018] A cover plate is disposed on the side of the positioning ring opposite to the positioning seat, and closes the opening of the positioning ring.

[0019] Preferably, a positioning post is provided on the side of the cover near the positioning seat, and a positioning hole is provided on the positioning seat, with the positioning post and the positioning hole being inserted into each other.

[0022] Watch manufacturing equipment, including knob assembly fixtures.

[0023] The beneficial effects of this utility model are:

[0024] This utility model's knob assembly fixture, when installing a knob into the mounting hole, first places the housing on one side of the positioning seat and positions the housing using a positioning component, making it difficult for the housing to move on the surface of the positioning seat. Then, the cover is positioned and placed on the positioning seat, making it difficult for the housing to move along the surface perpendicular to the positioning seat, further precisely positioning the housing. At the same time, the positioning through hole opened along the axial direction of the mounting hole guides and limits the knob and / or pressure tool. Finally, the knob is pressed into the mounting hole along the axial direction of the knob, thereby reducing the difficulty of knob installation, improving installation efficiency, and preventing damage to both the housing and the knob, thus reducing production losses.

[0038] The following reference Figures 1 to 4 The present invention describes the knob assembly fixture and watch production equipment provided by this utility model.

[0039] The watch manufacturing equipment includes a base, a positioning drive, an assembly drive, and a knob assembly fixture. Specifically, the base is vertically arranged, with a support connected to one side. The knob assembly fixture is located on the support and is used to position the housing with mounting holes to precisely install the knob into the mounting holes. Optionally, in some other embodiments, the base may also be tilted or horizontally arranged.

[0040] Furthermore, the positioning drive is connected to the base. In this embodiment, the positioning drive is a clamping cylinder, and two are arranged horizontally. The two positioning drives press the knob assembly fixture onto the base, thus achieving the positioning of the knob assembly fixture. The assembly drive is located above the knob assembly fixture and connected to the base. In this embodiment, the assembly drive is a cylinder, and the movement direction of the cylinder's piston rod coincides with the axis of the knob. Optionally, in other embodiments, the positioning drive and the assembly drive can also be other linear drive components.

[0041] Reference Figure 1 and Figure 2The knob assembly fixture includes a positioning base 1, a positioning component 2, a cover 3, and a limiting clip 4. The positioning component 2 is located on one side of the positioning base 1 and can position the outer shell. The cover 3 is positioned and covers the side of the positioning base 1 near the positioning component 2. The inner wall of the cover 3 can abut against the outer shell. A positioning through hole 311 is opened on the cover 3 along the axial direction of the mounting hole at the position corresponding to the mounting hole. The limiting clip 4 is engaged with the top of the cover 3.

[0042] Reference Figure 3 In this embodiment, the positioning seat 1 is vertically arranged, and a positioning groove 12 is formed on one side of the positioning seat 1, extending upward through the positioning seat 1. A limiting cover 13 is detachably connected inside the positioning groove 12. The side of the limiting cover 13 facing away from the positioning groove 12 is flush with the surface of the positioning seat 1, and the limiting cover 13 is detachably connected to the positioning seat 1 by bolts. A sliding groove 11 is also formed on one side of the positioning seat 1. The depth of the sliding groove 11 is greater than the depth of the positioning groove 12, and the lowest point of the sliding groove 11 is set lower than the lowest point of the sliding groove 11, so that the limiting cover 13 covers part of the opening of the sliding groove 11. Optionally, in some other embodiments, the positioning groove 12 may be omitted.

[0043] Specifically, the positioning component 2 includes a first positioning element 21 and a second positioning element 22. The first positioning element 21 and the second positioning element 22 are spaced apart and the distance between them is adjustable. The opposite sides of the first positioning element 21 and the second positioning element 22 can abut against the inner ring of the outer casing. Exemplarily, in this embodiment, the first positioning element 21 and the second positioning element 22 are distributed in a vertical direction, thereby positioning the outer casing by setting the first positioning element 21 and the second positioning element 22 with an adjustable distance on the inner ring of the outer casing.

[0044] Optionally, in some other embodiments, the first positioning member 21 and the second positioning member 22 may also be distributed in a horizontal direction, and the first positioning member 21 and / or the second positioning member 22 may be divided into multiple spaced components; in some other embodiments, the side of the first positioning member 21 and the second positioning member 22 that is close to each other may be abutted against the inner ring of the outer shell, which can also achieve positioning of the outer shell.

[0045] Specifically, in this embodiment, the first positioning member 21 includes a first positioning plate 211 and a first positioning protrusion 212 connected to one side of the first positioning plate 211. A clearance hole 131 is provided on the limiting cover 13, and the first positioning plate 211 is placed inside the clearance hole 131. The first positioning plate 211 is detachably connected to the positioning seat 1 by bolts. The detachable first positioning member 21 facilitates replacement to accommodate different shapes of first positioning members 21, improving the adaptability of the knob assembly fixture. Simultaneously, the clearance hole 131 limits the movement of the first positioning member 21, preventing it from sliding or rotating on the surface of the positioning groove 12.

[0046] Furthermore, in this embodiment, the second positioning member 22 includes a second positioning plate 221 and a second positioning protrusion 222 connected to one side of the second positioning plate 221. The second positioning plate 221 is slidably disposed inside the sliding groove 11 along the distribution direction of the first positioning member 21 and the second positioning member 22, and the second positioning protrusion 222 protrudes out of the sliding groove 11. It should be noted that when the second positioning plate 221 is at its lowest position, a portion of the second positioning plate 221 is still located on the side of the limiting cover 13 near the sliding groove 11. Thus, the limiting cover 13 always limits the second positioning plate 221, preventing it from disengaging from the sliding groove 11, thereby limiting the second positioning member 22.

[0047] Based on the above, when the housing needs to be positioned, the housing is first placed on one side of the positioning seat 1, and the first positioning member 21 and the second positioning member 22 are located in the inner ring of the housing. By sliding the second positioning plate 221, the second positioning protrusion 222 and the first positioning protrusion 212 simultaneously abut against the inner ring of the housing, thereby achieving the positioning of the housing.

[0048] Optionally, in some other embodiments, the first positioning member 21 and the second positioning member 22 can be slidably connected to the positioning seat 1, which can also realize the adjustment of the distance between the first positioning member 21 and the second positioning member 22.

[0049] Furthermore, to facilitate the sliding of the second positioning member 22, a driving waist hole 14 is provided on the positioning base 1 along the sliding direction of the second positioning member 22, and an insertion hole 2211 communicating with the driving waist hole 14 is provided on the second positioning member 22. This allows an external driving member to be inserted into the insertion hole 2211 so that the driving member can drive the second positioning member 22 to slide.

[0050] Additionally, an elastic element 23 is provided between the second positioning element 22 and the first positioning element 21. When the opposite sides of the first positioning element 21 and the second positioning element 22 abut against the outer shell, the elastic element 23 is in a compressed state. In this embodiment, the elastic element 23 is preferably a spring, and two springs are arranged parallel to each other along the sliding direction parallel to the second positioning element 22. One end of the spring abuts against the side wall of the sliding groove 11, and the other end of the spring abuts against the second positioning element 22, and the spring is always in a compressed state. Thus, the spring can continuously apply a pushing force to the second positioning element 22, which can ensure the stability of the positioning assembly 2. Optionally, in some other embodiments, the elastic element 23 may also be other elastic components.

[0051] Reference Figure 4For example, the cover 3 includes a positioning ring 31 and a cover plate 32. The positioning ring 31 is sleeved on the outside of the positioning component 2, and the inner ring of the positioning ring 31 can position the outer shell. The cover plate 32 is connected to the side of the positioning ring 31 away from the positioning seat 1 and covers the opening of the positioning ring 31. In this embodiment, the shape of the inner ring of the positioning ring 31 is adapted to the shape of the outer ring of the outer shell, and the positioning through hole 311 is opened on the positioning ring 31. The inner ring of the positioning ring 31 can circumferentially limit the outer shell, preventing the outer shell from moving and achieving auxiliary positioning of the outer shell. The cover plate 32 limits the outer shell in a direction perpendicular to the positioning seat 1, making it difficult for the outer shell to detach from the positioning component 2, and achieving accurate positioning of the outer shell in all directions.

[0052] Since the cover 3 needs to be precisely placed on the positioning seat 1, a positioning post 312 is connected to the side of the positioning ring 31 near the positioning seat 1. The positioning post 312 is set perpendicular to the surface of the positioning seat 1, and two positioning posts 312 are arranged in parallel. A positioning hole 15 is opened on the positioning seat 1 for each positioning post 312, and a single positioning post 312 is inserted into a single positioning hole 15. In addition, a positioning head 213 is connected to the first positioning member 21. There are two positioning heads 213. An insertion groove 321 is opened on the cover plate 32 for each positioning head 213, and a single positioning head 213 is inserted into a single insertion groove 321.

[0053] Reference Figure 3 and Figure 4 Based on the above, after the housing is positioned by the positioning component 2, the cover 3 is placed on one side of the positioning seat 1. The cover 3 is precisely positioned by the insertion and engagement of the positioning pin 312 with the positioning hole 15 and the positioning head 213 with the insertion slot 321, ensuring the cover 3 is accurately placed on one side of the positioning seat 1. This further precisely positions the housing. Then, the knob can be placed in the mounting hole through the positioning through hole 311. The workpiece is then used to apply pressure to the knob along the axial direction of the positioning through hole 311, precisely installing the knob into the mounting hole. This reduces installation difficulty, improves installation efficiency, and minimizes damage to both the housing and the knob, reducing production losses.

[0054] Reference Figure 2 and Figure 4 Furthermore, the limiting clip 4 is located on the top of the cover 3. Each positioning through hole 311 on the limiting clip 4 is coaxially connected to an elastic post 41, with one end of the elastic post 41 extending into the interior of the positioning through hole 311. When the limiting clip 4 is engaged on the top of the cover 3, the two elastic posts 41 can be driven by the assembly drive component to slide axially along the positioning through hole 311, i.e., along the axial direction of the mounting hole, thereby pressing the knob into the mounting hole and achieving precise installation of the knob. In addition, the elastic posts 41 can automatically reset after the assembly drive component is depressurized, further improving installation efficiency.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
