[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] The drive unit 4 in the prior art, such as components such as a cylinder or an electric push rod, usually has only one degree of freedom in one direction, which is defined as the first direction. When the drive end of the drive unit 4 is subjected to a force in the first direction, the drive unit 4 can offset the external force through its own power or the displacement of the drive end, and will not cause damage to the drive unit 4. However, when the drive end of the drive unit 4 is subjected to an external force in a direction other than the first direction, the drive end and other parts of the drive unit 4 will be squeezed, resulting in damage to the drive unit 4. During the assembly process of a watch, the drive unit 4 in the watch body clamping device is often subjected to an external force in a direction other than the first direction. In order to solve the above problem, the present application proposes a watch body clamping device.

[0031] Please refer to Figure 1 As shown, in an embodiment of the utility model, a watch body clamping device is provided, including a support frame 1, a driving unit 4, a clamping member 3 and a sliding member 2, the support frame 1 having a working surface for placing a watch body 7, the driving unit 4 is arranged on the support frame 1, the driving unit 4 has two driving parts that reciprocate along a first direction, the number of the clamping members 3 and the number of the sliding members 2 are consistent with the number of the driving parts, and the clamping members 3, the sliding members 2 and the driving parts correspond to each other, and the corresponding clamping members 3 are connected to the driving parts through the sliding member 2; at least part of the clamping members 3 is located above the working surface, and the two clamping members 3 are used to cooperate with each other to clamp the watch body 7 along the first direction, the sliding member 2 has and can transmit the torque exerted on the clamping member 3 to the force transmission part on the support frame 1 along the second direction, the force transmission part is in movably contact with the support frame 1, and the second direction is arranged at an angle to the first direction.

[0032] Specifically, the support frame 1 refers to a component that can play a supporting role, and has a working surface on the support frame 1. The working surface can be set at the top of the support frame 1 or at other places of the support frame 1. And the sliding member 2 refers to a component with a certain volume. The two sliding members 2 are slidably set on the support frame 1 and are respectively connected to the two driving ends of the driving unit 4. The two sliding members 2 can move away from or approach each other under the action of the driving unit 4, thereby driving the clamping members 3 set on the sliding members 2 to move away from or approach each other. The force transmission part is a part of the sliding member 2 that is generally rigid and can transmit torque. When the two clamping members 3 move away from each other under the drive of the driving unit 4, the watch body 7 can be loosened. When the two clamping members 3 move closer to each other under the drive of the driving unit 4, the watch body 7 is clamped and fixed by the clamping member 3, and the position of the watch body 7 can also be fixed.

[0033] The watch body clamping device provided by the embodiment of the utility model, when clamping the watch body 7, the driving unit 4 drives the two sliding members 2 to move away from or towards each other along the first direction, and at the same time drives the clamping members 3 set on the two sliding members 2 to move away from or towards each other, so as to achieve the clamping or loosening of the watch body 7 by the clamping members 3, which can ensure the accurate position and firm fixation of the watch body 7. Compared with the clamping device of the prior art, by connecting the clamping member 3 with the sliding member 2, and the sliding member 2 having and being able to transmit the torsion force received by the clamping member 3 to the force transmission part on the support frame 1 along the second direction, the second direction is set at an angle with the first direction. After the watch body 7 is clamped by the clamping member 3 under the action of the driving unit 4, and when the bottom cover needs to withstand a large torque when installing, the torque borne by the watch body 7 can be transmitted to the sliding member 2 through the clamping member 3, and the sliding member 2 has and can transmit the torque borne by the clamping member 3 to the force transmission part on the support frame 1 along the second direction. Therefore, the sliding member 2 can transmit the torque to the entire support frame 1 along the second direction, and offset part of the torque along the second direction through the support frame 1, thereby avoiding the torque along the second direction from being transmitted to the driving unit 4. Since the driving part on the driving unit 4 only has the degree of freedom to move along the first direction, offsetting part of the torque along the second direction by the support frame 1 and transmitting it to the driving unit 4 can reduce the risk of damage to the driving unit 4 due to torque to a certain extent, effectively protect the driving unit 4 such as the power part 41, and extend the service life of the watch body clamping device.

[0034] It should be noted that the drive unit 4 can use an integral component having two drive ends that can move relative to each other, such as a clamping cylinder or other components. The drive unit 4 can also use two independent components to form a component, such as using two independent cylinders to work simultaneously, both of which have drive ends and the two drive ends can move relative to or away from each other, which can be freely selected according to the situation.

[0035] In one embodiment, Figure 3 As shown, the sliding member 2 includes a sliding portion 21 and a connecting portion 22, the sliding portion 21 is slidably connected to the support frame 1 and is also connected to the driving portion 43, the clamping member 3 is connected to the sliding portion 21 through the connecting portion 22, and the connecting portion 22 can transfer the torque received by the clamping member 3 to the sliding portion 21, and the force transmission portion is the sliding portion 21. Specifically, the sliding portion 21 refers to a component with a certain volume, which can be any of a block, a plate or a column, etc. The sliding portion 21 as a whole can be arranged along the second direction, so that the sliding portion 21 can transfer the torque along the second direction. The connecting portion 22 can be a component with a certain volume, which can be any of a block, a plate or a column, etc. At this time, when the clamping part receives torque, the torque can be conveniently transmitted to the sliding part 21 through the connecting part 22. The sliding part 21, as a force transmission part, can transmit the torque to the support frame 1 along the first direction. The torque is offset by the support of the support frame 1, thereby reducing the torque transmitted to the drive unit 4 to a certain extent, thereby achieving the protection of the drive unit 4 and extending its service life.

[0036] In an optional embodiment, if Figure 1 As shown, the top of the connecting part 22 is protruding from the working surface, the clamping member 3 is arranged at the top of the connecting part 22, and the top member 12 is provided with an escape opening for avoiding the connecting part 22. Specifically, since the sliding member 2 is arranged below the top member 12, the position of the clamping member 3 can be higher than the working surface setting on the top member 12 through the setting of the connecting part 22, so that it is more convenient for the clamping member 3 to clamp the watch body 7. In addition, the top member 12 is provided with an escape opening for avoiding the connecting part 22, and when the sliding member 2 drives the connecting part 22 and the clamping member 3 to move, the setting of the escape opening can prevent the top member 12 from blocking and interfering with the movement of the connecting part 22.

[0037] In one embodiment, Figure 2As shown, the support frame 1 includes a bottom member 11, a top member 12 and two side supports 13, the top member 12 and the bottom member 11 are spaced apart, the two side supports 13 are spaced apart along the second direction between the bottom member 11 and the top member 12, the side supports 13 are connected to the bottom member 11 and the top member 12, the sliding portion 21 is slidably disposed between the two side supports 13, and the working surface is located on the side of the top member 12 away from the bottom member 11. Specifically, the bottom member 11, the top member 12 and the side supports 13 can all refer to plate-like components with a certain thickness. The bottom member 11, the top member 12 and the side supports 13 are plate-like, which can make the entire support frame 1 lighter. Of course, the bottom member 11, the top member 12 and the side supports 13 can also adopt other shapes or methods, which will not be described in detail here. The entire support frame 1 is formed by two spaced-apart side supports 13 arranged between the top member 12 and the bottom member 11, and an installation space can be formed between the two side supports 13. By arranging the two sliding members 2 and the drive unit 4 in the installation space, the structural layout of the entire clamping device can be made more compact and reasonable, and the space occupied by the entire clamping device can be reduced. The support frame 1 adopts the above structure. When the watch body 7 is subjected to torsion, the torsion borne by the watch body 7 can be transferred to the sliding member 2 through the clamping member 3, and then the torsion is transferred to the side support member 13 through the contact between the sliding member 2 and the side support member 13, and then the torsion is transferred to the bottom member 11 through the connection between the side support member 13 and the bottom member 11. In addition, the top member 12 is used to place and support the watch body 7, and the top member 12 also plays the role of connecting the two side supports 13, so that the installation of the side support member 13 is more secure, and the entire support frame 1 can withstand greater torsion.

[0038] Among them, Figure 2As shown, the two side supports 13 are fixed to the bottom member 11 by fasteners, which ensures the installation efficiency and makes the connection between the side supports 13 and the bottom member 11 more secure. In addition, the side supports 13 and the bottom member 11 are provided with positioning pin holes with matching positions, and positioning pins are provided in the positioning pin holes to further position the side supports 13 and the bottom member 11, which can ensure the accurate installation position of the side supports 13 on the bottom member 11, and the setting of the positioning pin holes can make the connection between the two more secure, thereby increasing the torsion resistance of the side supports 13 and the bottom member 11. Similarly, the two side supports 13 are fixed to the top member 12 by fasteners, which ensures the installation efficiency and makes the connection between the side supports 13 and the top member 12 more secure. In addition, positioning pin holes with matching positions are provided on the side support member 13 and the top member 12, and positioning pins are provided in the positioning pin holes to further position the side support member 13 and the top member 12, which can ensure that the side support member 13 is accurately installed on the top member 12, and the connection between the two can be made stronger through the setting of the positioning pin holes, thereby increasing the torsional resistance of the side support member 13 and the top member 12, making the overall structure of the support frame 1 more solid.

[0039] In an optional embodiment, if Figure 2 As shown, the drive unit 4 includes a power part 41, a drive rail 42 and two drive parts 43, the power part 41 is located between the two side supports 13, the drive rail 42 is located on the power part 41, the drive rail 42 is arranged along the first direction, the two drive parts 43 are slidably arranged on the drive rail 42, and the two sliding parts 21 are respectively connected to the drive parts 43, wherein the drive part 43 is the drive part of the drive unit 4. The sliding part 21 is connected to the drive part 43, and the sliding part 21 is connected to the drive part 43 by fasteners, so that the connection between the sliding part 21 and the drive part 43 can be more firmly. In addition, a pin connection part 22 is also arranged between the sliding part 21 and the drive part 43, so that the installation position of the sliding part 21 on the drive part 43 can be more accurate, and in addition, the shear force resistance capacity of the connection between the sliding part 21 and the drive part 43 can be further increased, so that the connection between the two can be more firmly. The power unit 41 is disposed on the bottom member 11 and is located on the two side supports 13, so that the installation of the drive unit 4 can be more space-saving. At the same time, the power unit 41 and the bottom member 11 can be fixed by connecting screws or positioning pins, so that the installation of the drive unit 4 is more secure.

[0040] In this embodiment, when the watch body 7 is subjected to torque, the torque transmission process is as follows:

[0041] When the clamp is tightened and the cover is rotated to install the cover, the bottom cover of the body 7 will be subjected to torque. The torque on the bottom cover of the body 7 will first be transmitted to the clamp, and then transmitted to the connecting part 22 through the clamp. When a connecting screw or a positioning pin is provided between the clamp and the connecting part 22, the torque will be transmitted through the connecting screw or the positioning pin. After the torque is transmitted to the connecting part 22, it will continue to be transmitted to the sliding part 21. When a connecting screw or a positioning pin is provided between the sliding part 21 and the connecting part 22, the torque will be transmitted through the connecting screw or the positioning pin. Then the sliding part 21 will transmit the torque to the side support 13 along the second direction, and finally the torque will be transmitted to the bottom part 11 along the side support 13. When a connecting screw or a positioning pin is provided between the side support 13 and the bottom part 11, the torque will be transmitted through the connecting screw or the positioning pin. At the same time, when the side support 13 is subjected to torque, the top part 12 will also connect the two side supports 13, so that the side support 13 has a stronger ability to withstand torque. In addition, when the sliding portion 21 is subjected to torsional force, most of the torsional force is transmitted to the side support member 13 along the first direction, and a small part of the torsional force is transmitted to the drive unit 4 through the drive end of the drive unit 4. When a connecting screw or a positioning pin is provided between the drive end and the sliding portion 21, the torsional force will be transmitted through the connecting screw or the positioning pin, and finally a part of this torsional force will be transmitted to the bottom component 11 through the drive unit 4. Similarly, when a connecting screw or a positioning pin is provided between the main body of the drive unit 4 and the bottom component 11, the torsional force will be transmitted through the connecting screw or the positioning pin, so that the force on the entire device is more even.

[0042] In one embodiment, Figure 2 As shown, a sliding structure is also provided on the side support member 13, and the sliding member 2 is slidably connected to the side support member 13 through the sliding structure. The sliding member 2 can transmit the torque received to the side support member 13 through the sliding structure. Specifically, the setting of the sliding structure can make it easier for the sliding member 2 to slide between the two side supports 13. At the same time, sliding structures are provided on both side supports 13, and the two sides of the sliding member 2 are respectively slidably connected to the side supports 13 through the sliding structures, which can make the sliding of the sliding member 2 more stable and also enable the sliding member 2 to better transmit the torque to the side support member 13. The sliding structure is described in detail below. It should be understood that the sliding structure can take a variety of forms, not limited to the structure described below, and can be freely selected according to actual conditions and will not be repeated here.

[0043] like Figure 4As shown, the sliding structure includes a sliding groove 5 arranged on the side support 13, at least a part of the sliding part 21 is slidably arranged in the sliding groove 5, and the sliding part 21 abuts against the bottom surface of the sliding groove 5. Specifically, the sliding groove 5 refers to a groove structure that is recessed on the side support 13 and has a certain length. The bottom surface of the sliding groove 5 refers to the inner wall arranged opposite to the mouth, and the bottom surface of the sliding groove 5 is generally perpendicular to the second direction. The two ends of the sliding part 2 are respectively slidably arranged in the sliding grooves 5 on the two side supports 13, which can make the sliding of the sliding part 2 more convenient and stable. At the same time, the sliding part 21 abuts against the bottom surface of the sliding groove 5, and when the sliding part 21 is subjected to a torsion along the second direction, the sliding part 21 can be supported by the bottom surface of the sliding groove 5, thereby realizing the transmission of the torsion from the sliding part 21 to the side support 13.

[0044] In addition, a sliding guide structure, such as a roller or a graphite guide plate, may be provided between the sliding member 2 and the inner wall of the sliding groove 5 to enable the sliding member 2 to slide more smoothly in the sliding groove 5 .

[0045] Optionally, the sliding structure can also be a sliding guide rail set on the side support member 13, and a structure for cooperating with the sliding guide rail is set on the sliding member 2, such as a sliding groove or two sliding cover plates set at intervals, etc., which can also serve the purpose of sliding connection between the sliding member 2 and the side support member 13.

[0046] In one embodiment, Figure 2 As shown, a first positioning groove 6 for limiting the position of the side support member 13 is also provided on the bottom member 11. The length direction of the first positioning groove 6 extends along the first direction. The first positioning groove 6 is used to prevent the side support member 13 from moving or tilting along the second direction, and at least a part of the side support member 13 is fixed inside the first positioning groove 6. Specifically, the first positioning groove 6 refers to a groove structure with a certain depth. The side support member 13 is inserted into the first positioning groove 6, and one side surface of the side support member 13 contacts the bottom surface of the first positioning groove 6. At the same time, the cross section of the first positioning groove 6 matches the cross section of the side support member 13. When the side support member 13 is inserted into the first positioning groove 6, the side support member 13 is limited by the side wall of the first positioning groove 6, so that the installation position of the side support member 13 can be more accurate, the installation size is accurate, the rigidity and strength meet the requirements, and the sliding part 21 can slide more smoothly between the two side supports 13.

[0047] Among them, Figure 2 As shown, screw holes and positioning pin holes are also provided at the bottom of the first positioning groove 6. After the side support member 13 is installed into the first positioning groove 6, the bottom member 11 and the side support member 13 can be fixed by fasteners. Of course, the bottom member 11 and the side support member 13 can be fixed by other methods.

[0048] In one embodiment, Figure 2 As shown, the top of the connecting portion 22 is provided with a second positioning groove 8 for limiting the position of the clamping member 3. Specifically, the second positioning groove 8 refers to a groove structure with a certain depth, and one side of the second positioning groove 8 is open. The size of the second positioning groove 8 matches the size of the end of the clamping member 3. When the clamping member 3 is fixed, the end of the clamping member 3 is installed in the second positioning groove 8, and the clamping member 3 extends to the outside of the second positioning groove 8 through the open side of the second positioning groove 8. The clamping member 3 is limited by the side wall of the second positioning groove 8, so that the installation position of the clamping member 3 is more accurate.

[0049] In one embodiment, Figure 3 As shown, the clamping member 3 is detachably connected to the connecting portion 22. Specifically, the detachable connection means that the clamping member 3 can be easily removed from the connecting portion 22, and the corresponding clamping member 3 can be conveniently replaced according to the size of the watch body 7, so that the clamping of the watch body 7 is simpler and more convenient.

[0050] In an optional embodiment, if Figure 2 As shown, a screw hole is provided on the bottom surface of the second positioning groove 8. After the clamp 3 is placed inside the second positioning groove 8, a fastener can be used to penetrate the clamp 3 and then be threadedly connected to the screw hole, which ensures that the clamp 3 is firmly installed and is more convenient to disassemble.

[0051] In one embodiment, Figure 1 As shown, a vacuum unit 9 is also provided on the support frame 1, and the vacuum unit 9 is used to fix the watch body 7 in a pre-fixed area on the working surface, and the pre-fixed area is located between the two clamping members 3. Specifically, the vacuum unit 9 refers to a component that can generate negative pressure in a local area, such as a vacuum suction head and other components. The vacuum unit 9 generally needs to be connected to an external negative pressure device, and the negative pressure device is used to generate negative pressure at the vacuum suction cup to suck the object tightly. By providing the vacuum unit 9 on the support frame 1, the watch body 7 can be pre-fixed before the clamping member 3 clamps the watch body 7, which can make the fixing of the watch body 7 more convenient and the fixing position more accurate. In addition, the vacuum unit 9 is generally provided on the top member 12, and the vacuum unit 9 can be directly placed on the working surface. When the watch body 7 is fixed, the watch body 7 can be directly placed on the vacuum unit 9; the vacuum unit 9 can also be provided below the top member 12, and a connection hole connected to the vacuum unit 9 is provided on the top member 12, and the watch body 7 can be adsorbed by the vacuum unit 9 when the watch body 7 is placed on the working surface, which can make the clamping and fixing of the watch body 7 more convenient and quick.

[0052] In one embodiment, Figure 3As shown, the clamping member 3 includes a main body 32 and a clamping member 31, the main body 32 is connected to the sliding member 2, the clamping member 31 is arranged at the end of the main body 32 close to the watch body 7, and the clamping member 31 is detachably connected to the main body 32. Specifically, the clamping member 31 and the main body 32 both refer to components with a certain volume, the clamping member 31 is arranged at the end of the main body 32 close to the watch body 7, and when the clamping member 3 is close to the watch body 7, it can contact the watch body 7 through the clamping member 31. The clamping member 3 is divided into two independent parts, the main body 32 and the clamping member 31. The clamping member 31 can be made of a material with higher hardness, such as some hard and wear-resistant materials such as steel or bakelite, to avoid wear of the clamping member 31 and increase the service life of the clamping member 31. The main body 32 is made of ordinary materials, which can save the overall manufacturing cost of the clamping member 3.

[0053] The clamping part 31 is detachably connected to the main body 32, and the detachable connection can be plugged and fixed. For example, a plugging slot is provided at the end of the clamping part 3, and a plugging part matching the plugging slot is provided on the clamping part 31, so that only the clamping part 31 can be replaced according to the model of the watch body 7 without replacing the entire clamping part 3. In addition, a clamping structure that is mutually compatible with the watch body 7 can also be provided on the clamping part 31, for example, two positioning surfaces that are mutually spaced along the second direction are provided on the clamping part 31, and when the clamping part 31 approaches the watch body 7 along the first direction, the two positioning surfaces are respectively pressed against the inner sides of the two lugs to achieve positioning of the watch body 7, thereby preventing the watch body 7 from moving along the second direction; a positioning groove can also be provided on the clamping part 31, and the positioning groove is arc-shaped and its curvature is adapted to the watch body 7. When the clamping part 31 contacts the watch body 7, the contact area between the clamping part 31 and the watch body 7 can be increased, so that the watch body 7 is clamped and fixed more firmly. Of course, it should be understood that the positioning surface and the positioning groove can exist on the clamping portion 31 at the same time to improve the firmness of clamping the watch body 7.
