Description

Technical Field

[0001] This utility model relates to the technical field of watch case polishing equipment, and specifically to a watch case polishing machine clamping mechanism. Background Technology

[0002] The watch case (also known as the bezel) is a component of the watch casing, usually made of metal. It serves to decorate and protect the internal parts of the watch. During production, the outer surface of the watch case needs to be polished to create a sandblasted texture, giving the watch case a hazy appearance.

[0003] Currently, watch cases are polished using a watch case polishing machine. This machine mainly consists of a clamping mechanism and a polishing mechanism. The clamping mechanism has chucks and a clamping cylinder. The clamping cylinder drives the chucks to open and close, clamping or releasing the watch case. The grinding wheel on the polishing mechanism polishes the watch case. However, due to the unreasonable design of traditional clamping mechanisms, excessive force on the watch case during polishing can easily lead to excessive wear or even damage. Utility Model Content

[0004] This utility model addresses the deficiencies in existing technology by providing a watch case polishing machine clamping mechanism that provides an elastic buffering effect on the watch case, preventing excessive force on the watch case during polishing and thus preventing excessive wear or even damage to the watch case.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A watch case polishing machine clamping mechanism includes a translational flip clamping assembly, wherein the translational flip clamping assembly has a base, a translational seat movably disposed on the base, a flipping seat rotatably disposed on the translational seat, and a clamping module disposed on the flipping seat;

[0007] The base and the translation seat are provided with a first elastic driving member and a second elastic driving member that are arranged opposite to each other. The first elastic driving member drives the translation seat to move linearly in a first direction, and the second elastic driving member drives the translation seat to move linearly in a second direction. The first direction and the second direction are opposite.

[0008] The flipping seat is rotatably connected to the translation seat via a rotating shaft. A third elastic drive member and a fourth elastic drive member are provided between the translation seat and the flipping seat. The third elastic drive member drives the flipping seat to rotate clockwise around the rotating shaft, and the fourth elastic drive member drives the flipping seat to rotate counterclockwise around the rotating shaft. The clamping module moves with the flipping seat.

[0009] By setting a base, a movable sliding seat on the base, a rotating flip seat on the sliding seat, and a clamping module on the flip seat, and by setting corresponding first and second elastic driving members, the sliding seat is elastically driven by the first and second elastic driving members, so that the sliding seat has an elastic buffering effect in the first and second directions; and by setting corresponding third and fourth elastic driving members, the flip seat has an elastic buffering effect when it swings around the axis, so that the clamped watch case has an elastic buffering effect, avoiding excessive force on the watch case during polishing, and preventing excessive wear or even damage to the watch case.

[0010] In one embodiment, both the first elastic drive member and the second elastic drive member are first cylinders, the first piston rod on the first cylinder abuts against the translation seat or base, and the first cylinder is connected to an external air source through a first proportional valve.

[0011] In one embodiment, the first cylinder is mounted on a base, and the first piston rod on the first cylinder abuts against the translation seat.

[0012] In one embodiment, the cylinder body of the first cylinder is integrally formed with the base, and the piston chamber inside the first cylinder forms an opening through the outer wall of the base, with a sealing cap provided at the opening.

[0015] In one embodiment, the third elastic drive member and the fourth elastic drive member are both second cylinders, the second piston rod on the second cylinder abuts against the tilting seat or the translation seat, and the second cylinder is connected to an external air source through a second proportional valve.

[0016] In one embodiment, the flipping seat is provided with two support parts spaced apart, each support part having a shaft hole, the two ends of the rotating shaft being movably inserted into the corresponding shaft holes, a receiving cavity being provided between the two support parts, and the lower part of the clamping module being movably disposed in the receiving cavity.

[0017] In one embodiment, the central axis of the rotating shaft is perpendicular to the direction of movement of the translation seat.

[0018] In one embodiment, the component further includes a rotation drive assembly that drives the translational flip clamping assembly to rotate. The rotation center line of the translational flip clamping assembly is perpendicular to the central axis of the rotating shaft, and the rotation center line of the translational flip clamping assembly is perpendicular to a first direction.

[0019] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, by setting a base, a translation seat movably set on the base, a flip seat rotatably set on the translation seat, and a clamping module set on the flip seat, and setting corresponding first and second elastic driving members, the translation seat is elastically driven by the first and second elastic driving members, so that the translation seat has an elastic buffering effect in the first and second directions; and by setting corresponding third and fourth elastic driving members, the flip seat has an elastic buffering effect when swinging around the axis, so that the clamped watch case has an elastic buffering effect, avoiding excessive force on the watch case during polishing, and preventing excessive wear or even damage to the watch case.

Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figure 1-5 As shown, this utility model discloses a watch case polishing machine clamping mechanism, including a translational flip clamping assembly 10. The translational flip clamping assembly 10 has a base 11, a translational seat 12 movably disposed on the base 11, a flipping seat 13 rotatably disposed on the translational seat 12, and a clamping module 14 disposed on the flipping seat 13.

[0031] The base 11 and the translation seat 12 are provided with a first elastic drive member 111 and a second elastic drive member 112 arranged opposite to each other. The first elastic drive member 111 drives the translation seat 12 to move linearly in a first direction A, and the second elastic drive member 112 drives the translation seat 12 to move linearly in a second direction B. The first direction A and the second direction B are opposite to each other, and both the first direction A and the second direction B are parallel to the X-axis.

[0032] The flipping seat 13 is rotatably connected to the translation seat 12 via a rotating shaft 131. The central axis of the rotating shaft 131 is perpendicular to the direction of movement of the translation seat 12, and the central axis of the rotating shaft 131 is parallel to the Y-axis.

[0033] A third elastic drive member 121 and a fourth elastic drive member 122 are provided oppositely between the translation seat 12 and the flip seat 13. The third elastic drive member 121 drives the flip seat 13 to rotate clockwise around the rotating shaft 131, and the fourth elastic drive member 122 drives the flip seat 13 to rotate counterclockwise around the rotating shaft 131. The clamping module 14 moves with the flip seat 13. The clamping module 14 is used to clamp the watch case 30. The clamping module 14 is a mature existing technology, so it will not be described in detail.

[0034] In this configuration, both the first elastic drive member 111 and the second elastic drive member 112 are first cylinders. The first piston rod 1111 on the first cylinder abuts against the translation seat 12. The first cylinder is connected to an external air source through a first proportional valve (not shown). When air supplied from the external source enters the first cylinder, the first piston rod 1111 extends outward to push against the translation seat 12. The first proportional valve is a commercially available mature product that can adjust the air pressure inside the first cylinder. By setting both the first elastic drive member 111 and the second elastic drive member 112 to be first cylinders, the first cylinder... An external air source is connected through a first proportional valve (not shown). The first proportional valve can adjust the air pressure in the first cylinder. Since the gas is compressible, the first piston rod 1111 can float axially in the piston chamber of the first cylinder, thereby indirectly achieving an elastic buffering effect for the translation seat 12 along its direction of movement. In addition, the first proportional valve can be used to finely adjust the force of the translation seat 12 moving in the first direction A or the second direction B, thereby ensuring that the translation seat 12 has an elastic buffering effect while ensuring a suitable degree of pressure between the watch case 30 and the polishing mechanism, and improving the polishing effect of the watch case 30.

[0035] The first cylinder is mounted on the base 11, and the first piston rod 1111 on the first cylinder abuts against the side wall of the translation seat 12.

[0036] It should be noted that the first cylinder can also be mounted on the translation seat 12. Correspondingly, the first piston rod 1111 abuts against the base 11. The first elastic drive member 111 and the second elastic drive member 112 can also adopt a drive structure of linear drive unit + elastic block. The linear drive unit drives the elastic block to move linearly, so that the elastic block pushes against the translation seat 12 or the base 11. The elastic block can elastically deform along its own movement direction. The linear drive unit can be a screw + motor structure.

[0037] The cylinder body of the first cylinder is integrally formed with the base 11. The piston chamber inside the first cylinder has an opening (not shown) through the outer wall of the base 11. A sealing cover 113 is provided at the opening. By adopting an integral forming design, the structure of the first cylinder and the base 11 is more compact and occupies less space. The opening facilitates the installation and disassembly of the first piston rod 1111.

[0038] A guide structure 114 is provided between the base 11 and the translation seat 12. The translation seat 12 is linearly and movably connected to the base 11 through the guide structure 114. By setting the guide structure 114, the movement of the translation seat 12 relative to the base 11 remains stable, thereby improving the polishing effect.

[0039] The guide structure 114 includes a guide rod 1141 and a guide hole 1142. The guide rod 1141 is disposed on the base 11, and the guide hole 1142 is disposed on the translation seat 12. There are two guide rods 1141 and two guide holes 1142.

[0040] The base 11 is provided with a groove 115, and the translation seat 12 is movably disposed in the groove 115. The first piston rod 1111 on the first cylinder extends into the groove 115. For example, the guide rod 1141 is disposed in the groove 115. By providing the groove 115, the translation seat 12 is movably disposed in the groove 115, making the assembly of the base 11 and the translation seat 12 more compact and occupying less space.

[0041] The third elastic drive member 121 and the fourth elastic drive member 122 are both second cylinders. The second piston rod 1211 on the second cylinder abuts against the tilting seat 13 or the translation seat 12. The second cylinder is connected to an external air source through a second proportional valve. Specifically, the second cylinder is located on the translation seat 12. The second piston rod 1211 on the second cylinder extends upward and abuts against the tilting seat 13. The cylinder body on the second cylinder is integrally formed with the translation seat 12. The second proportional valve has the same structure and principle as the first proportional valve.

[0042] It should be noted that the second cylinder can also be mounted on the tilting seat 13, and correspondingly, the second piston rod 1211 abuts against the translation seat 12.

[0043] The flip base 13 is provided with two spaced support parts 123, each with a shaft hole 124. The two ends of the rotating shaft 131 are movably inserted into the corresponding shaft holes 124. A receiving cavity 125 is provided between the two support parts 123, and the lower part 141 of the clamping module 14 is movably disposed in the receiving cavity 125. By providing two spaced support parts 123 on the flip base 13, each with a shaft hole 124, and the two ends of the rotating shaft 131 movably inserted into the corresponding shaft holes 124, the flip base 13 can be easily assembled onto the translation base 12. Furthermore, the receiving cavity 125 between the two support parts 123 and the lower part 141 of the clamping module 14 movably disposed in the receiving cavity 125 make the assembly structure of the clamping module 14, the flip base 13, and the translation base 12 more compact, while ensuring that the clamping module 14 has room to move, resulting in good practicality.

[0044] This utility model also includes a rotary drive assembly 20, which drives the translational flipping clamping assembly 10 to rotate around the Z-axis. The center line of the translational flipping clamping assembly 10 is parallel to the Z-axis. The rotary drive assembly 20 has a rotating seat 21 and a rotary drive unit 22 that drives the rotating seat 21 to rotate around the Z-axis. The base 11 is connected to the rotating seat 21 and the base 11 rotates with the rotating seat 21. Specifically, the rotary drive unit 22 can be a rotary motor or a rotary cylinder.

[0045] The working principle of this utility model is as follows: The watch case 30 is placed on the clamping module 14 and clamped. Under the drive of the rotation drive component 20, the translation and flipping clamping component 10 and the watch case 30 rotate synchronously with the rotating seat 21. Under the drive of the first elastic drive component 111 and the second elastic drive component 112, the translation seat 12 drives the flipping seat 13, the clamping module 14 and the watch case 30 to move linearly along the X-axis. Under the drive of the third elastic drive component 121 and the fourth elastic drive component 122, the flipping seat 13 drives the clamping module 14 and the watch case 30 to rotate around the rotating shaft 131.

[0046] In summary, this utility model, by setting a base 11, a translation seat 12 movably mounted on the base 11, a flip seat 13 rotatably mounted on the translation seat 12, and a clamping module 14 mounted on the flip seat 13, and by setting corresponding first elastic drive members 111 and second elastic drive members 112, uses the first elastic drive members 111 and second elastic drive members 112 to elastically drive the translation seat 12, so that the translation seat 12 has an elastic buffering effect in the first direction A and the second direction B; and by setting corresponding third elastic drive members 121 and fourth elastic drive members 122, the flip seat 13 has an elastic buffering effect when swinging around the rotating axis 131, so that the clamped watch case 30 has an elastic buffering effect, avoiding excessive force on the watch case 30 during polishing, and preventing excessive wear or even damage to the watch case 30.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
