DETAILED DESCRIPTION

[0028] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0029] Referring to Figures 2-7 The embodiment of the utility model discloses a watchcase wire drawing processing mechanism, which comprises a fixed plate 1 and a mounting plate 2 mounted at one end of the fixed plate 1. The watchcase wire drawing processing mechanism is a mechanism for winding and driving the rotation of a wire drawing belt 8 in the whole wire drawing processing equipment, and the whole watchcase wire drawing processing mechanism is integrated in the wire drawing processing equipment through the fixed plate 1. A driving wheel set 3 is rotatably mounted on the fixed plate 1. The mounting plate 2 is provided with an adjusting cylinder 4 and a support 5 slidably mounted on the cylinder. The telescopic rod of the adjusting cylinder 4 is connected to the support 5. A roller shaft 6 is rotatably mounted on the support 5. Two guide wheel sets 7 are arranged on the mounting plate 2 and located on the two sides of the adjusting cylinder 4 respectively. The wire drawing belt 8 is sleeved with the driving wheel set 3 and passes through the two guide wheel sets 7 and the roller shaft 6 in sequence. Thus, the wire drawing belt 8 is wound on the driving wheel set 3, the guide wheel set 7 and the roller shaft 6, and is synchronously rotated when the driving wheel set 3 is driven to rotate. The roller shaft 6 pushes the wire drawing belt 8 to tightly adhere to the surface of the watchcase to realize wire drawing processing.

[0030] As Figure 1The surface of the watch case structure shown in the embodiment is adapted to the wire drawing process, and has an arc convex surface and an arc concave surface. Thus, when the watch case rotates, the roller shaft 6 can always pull the wire drawing belt 8 to adhere to the surface of the watch case. The relative position of the roller shaft 6 is adjusted by adjusting the forward and backward movement of the cylinder 4 to pull the support 5, so that the wire drawing belt 8 adheres to the surface of the watch case for continuous wire drawing process, and the surface wire drawing process effect has continuity and consistency.

[0031] During the relative adjustment of the wire drawing belt 8, the wire drawing belt 8 needs to be kept tensioned. Specifically, a swing groove 20 is formed in the mounting plate 2, and a tensioning wheel set 9 is mounted on the mounting plate 2 and can swing along the swing groove 20. The tensioning wheel set 9 adheres to the inner side of the wire drawing belt 8. The tensioning wheel set 9 can swing relative to the swing groove 20 to adapt to the adjustment position of the wire drawing belt 8 pulled by the roller shaft 6, so that the wire drawing belt 8 is always in a tensioned state, and the wire drawing effect is ensured.

[0032] The tensioning wheel set 9 includes a swing rod 91 rotatably mounted at the bottom of the mounting plate 2. One end of the swing rod 91 is rotatably mounted with a fixed shaft 92. The fixed shaft 92 passes through one end of the swing groove 20 and is rotatably mounted with a first roller 93 through a bearing. The other end of the swing rod 91 is connected with at least one swing spring 94, and the end of the swing spring 94 is connected to the fixed plate 1. The swing state of the swing rod 91 is adjusted by the swing spring 94 to achieve tensioning. The first roller 93 is tightly attached to the inner side of the wire drawing belt 8 and rotates with the wire drawing belt 8 to rotate relative to the fixed shaft 92. Thus, when the wire drawing belt 8 is pulled and adjusted, the first roller 93 is pushed to swing towards the inside of the swing groove 20. Under the pulling action of the swing spring 94, the first roller 93 is tightly attached to the wire drawing belt 8. When the wire drawing belt 8 is adjusted to be relaxed, the first roller 93 is still tightly attached to the wire drawing belt 8 under the pulling action of the swing spring 94. Thus, during the adjustment of the wire drawing belt 8, the tensioning of the wire drawing belt 8 is achieved by the tensioning wheel set 9, and the wire drawing effect is ensured.

[0033] Specifically, a handle 95 extending outward is arranged on the swing rod 91. When the swing rod 91 needs to be adjusted, the handle 95 provides a force point.

[0034] During the rotation of the wire drawing belt 8, the two guide wheel sets 7 located on both sides of the adjusting cylinder 4 guide and adjust the angle of the wire drawing belt 8. Specifically, the guide wheel set 7 includes a connecting rod 71 fixed to the mounting plate 2. The connecting rod 71 is rotatably mounted with a second roller 72 through a bearing. The second roller 72 rotates relative to the connecting rod 71 to rotate with the wire drawing belt 8 to avoid damping effect on the wire drawing belt 8.

[0035] Meanwhile, in order to ensure the stable rotation of the wire drawing belt 8 and prevent it from being separated, the width of the first roller 93 and the second roller 72 is greater than the width of the wire drawing belt 8.

[0036] When the wire drawing belt 8 is continuously drawn to adapt to the arc convex surface and the arc concave surface of the watch case, the position of the roller shaft 6 is adjusted by adjusting the sliding position of the support 5 through the adjusting cylinder 4. Specifically, the support 5 includes an L-shaped sliding part 51, a sliding groove 52 is formed in the horizontal block of the sliding part 51, a guide groove 40 is arranged on the adjusting cylinder 4 and slidably matched with the horizontal block of the sliding part 51, and a guide strip 41 is arranged in the guide groove 40 and slidably matched with the sliding groove 52. A positioning block 53 is fixed to the vertical block of the sliding part 51, support blocks 54 are vertically arranged at both ends of the positioning block 53, and the roller shaft 6 is rotatably arranged on the two support blocks 54. The entire support 5 is stably connected to the adjusting cylinder through the cooperation of the guide groove 40 and the sliding part 51, and the cooperation of the sliding groove 52 and the guide strip 41, and the roller shaft 6 is rotatably arranged on the two support blocks 54, so that it can rotate following the rotation of the wire drawing belt 8 during the adjustment of the relative position. The wire drawing belt 8 is pushed or pulled back synchronously by moving the support 5 through the cylinder.

[0037] In order to meet the requirements of the roller shaft 6 to push the wire drawing belt 8 to adhere to the curved surface of the watch case during the wire drawing process, the roller shaft 6 is an elastic shaft, which is made of a metal material with rigid deformation.

[0038] Specifically, the driving wheel set 3 is a power transmission structure that transmits the power of the driving mechanism and drives the wire drawing belt 8 to rotate synchronously. The driving wheel set 3 includes a bearing seat 31 arranged on the fixed plate 1, a power shaft 32 rotatably arranged on the bearing seat 31, a rubber wheel 33 arranged on the power shaft 32 for winding the wire drawing belt 8, and a motor connecting sleeve 34 arranged at the other end of the power shaft 32. After being connected to the driving mechanism through the motor connecting sleeve 34, the power shaft 32 and the rubber wheel 33 rotate relative to the bearing seat 31, driving the wire drawing belt 8 to rotate.

[0039] In order to increase the friction between the rubber wheel 33 and the wire drawing belt 8 and make the wire drawing belt 8 rotate synchronously with the rubber wheel 33, a pattern 35 for increasing friction is arranged on the outer side of the rubber wheel 33 to improve the friction of the contact surface and ensure synchronous rotation.
