Description

Technical Field

[0001] This utility model relates to the field of watch assembly, and in particular to a vertical pressing device. Background Technology

[0002] With the rapid development of smartwatch technology, the assembly of watch components requires millimeter-level precision positioning and pressing of the product casing. Traditional pressing devices use linear motion to press and assemble the product. If fine adjustments to the downward pressure or position are needed, sensors or servo systems are required, increasing the complexity and cost of the control system. Moreover, the long stroke occupies more vertical space, which is not friendly to compact assembly environments. Direct pressing lacks mechanical cushioning and can easily damage precision parts. Utility Model Content

An extension arm extends from the top of the side wall of the sliding plate facing the cylinder and is connected to the piston rod of the cylinder. A mounting seat is slidably provided on the top of the extension arm. A pressure block is installed on the side of the mounting seat corresponding to the sliding plate. A guide block that can move synchronously with the mounting seat and is limited by the extension arm is installed on the side of the mounting seat corresponding to the cylinder. The lower part of the guide block has a guide slope that is downward and inclined towards the sliding plate. A deep groove ball bearing that movably abuts against the guide slope is also provided on the base.

[0007] Preferably, the mounting base has L-shaped horizontal extension feet extending downwards on both side walls parallel to the sliding direction of the mounting base, corresponding to the side of the sliding plate, with the horizontal ends facing the cylinder. The upper part of the sliding plate is located between the two extension feet. Two extension blocks corresponding to the horizontal ends of the two extension feet extend from the side wall of the extension arm. Two telescopic springs are provided and are correspondingly arranged between the two extension feet and the two extension blocks.

[0008] Preferably, the horizontal end of the extension foot and the opposing surfaces between the extension block are provided with spring mounting holes for mounting telescopic springs.

[0009] Preferably, the base has an L-shaped structure, the cylinder is installed at the horizontal end of the base, the sliding plate is slidably disposed at the vertical end of the base, and the deep groove ball bearing is installed at the top of the vertical end of the base.

[0010] Preferably, a top plate is installed on the top of the vertical end of the base, and a mounting bracket is installed on the top plate, with the deep groove ball bearing mounted on the mounting bracket.

[0019] Examples of embodiments of this utility model Figs. 1-2As shown, a vertical pressing device includes a base 1. A cylinder 2 with a piston rod that moves vertically and a sliding plate 3 that slides vertically are spaced apart on the base 1. The sliding plate 3 is located on the left side of the base 1 and slides up and down. The cylinder 2 with its piston rod also moves up and down is located on the right side of the base 1. The sliding plate 3 is slidably positioned using a vertical plate located between the sliding plate 3 and the cylinder 2 on the top surface of the base 1. Preferably, the base 1 is an L-shaped base consisting of a vertical end and a horizontal end. The cylinder 2 is mounted on the horizontal end of the base 1, and the sliding plate 3 is slidably positioned on the vertical end of the base 1, thus forming the vertical plate. The top of the side wall of the sliding plate 3 facing the cylinder extends to connect with the piston rod of the cylinder 2. The extended arm 30, sliding plate 3, and extended arm 30 together form an inverted L-shaped structure. The extended arm 30 is located above the cylinder 2. The sliding plate 3 and the piston rod of the cylinder 2 are located at opposite ends of the extended arm 30. The sliding plate 3 and the piston rod of the cylinder 2 are parallel. The movement of the piston rod of the cylinder 2 drives the sliding plate 3 to move synchronously. A piston rod mounting hole is provided on the extended arm 30, and the piston rod can be installed in the mounting hole. A mounting seat 4 is slidably provided on the top of the extended arm 30. A pressure block 5 is installed on the side of the mounting seat 4 corresponding to the sliding plate 3. A guide block 6, which can move synchronously with the mounting seat 4 and is limited by the extended arm 30, is installed on the side of the mounting seat 4 corresponding to the cylinder 2. The mounting seat 4 can slide in the left and right direction at the top of the extended arm 30. The pressure block 5 is installed on the left end of the mounting base 4 and is located to the left of the sliding plate 3. The guide block 6 is installed on the right side of the mounting base 4. As the mounting base 4 slides left and right, the guide block 6 abuts against the end of the extension arm 30, and the extension arm 30 prevents the guide block 6 from moving further. At this time, the mounting base 4 has a protrusion 42 extending from the side of the sliding plate 3 on the side corresponding to the sliding plate 3. The pressure block 5 is installed on the protrusion 42, that is, a protrusion 42 extending from the left end of the mounting base 4 and protruding from the left side wall of the sliding plate 3. During pressing, the pressing base for supporting the watch to be pressed is set on the worktable, located to the left of the sliding plate 3 and below the pressure block 5. The lower part of the guide block 6 has a guide slope 60 that slopes downward and towards the sliding plate 3. The base 1 also has A deep groove ball bearing 7 is provided, which movably abuts against the guide slope 60. The relative movement between the deep groove ball bearing 7 and the guide slope 60 ensures that the downward pressure is vertical. At this time, the deep groove ball bearing 7 is installed on the top of the vertical end of the base 1. The mounting structure is that a top plate 10 is installed on the top of the vertical end of the base 1, and a mounting bracket 100 is installed on the top plate 10. A rotating shaft extending above the guide slope is installed on the mounting bracket 100. The deep groove ball bearing 7 is installed on the rotating shaft. The top plate 10 and the mounting bracket 10 are integrally formed, and the deep groove ball bearing 7 is installed on the mounting bracket 100 through the rotating shaft. A telescopic spring 8 is provided between the mounting seat 4 and the extension arm 30, with both ends corresponding to the mounting seat 4 and the extension arm 30, and the axial direction is the same as the sliding direction of the mounting seat 4.

[0020] When pressed down, the piston rod of cylinder 2 retracts downward, the sliding plate 3 slides down, and the sliding plate 3 moves downward along with the mounting base 4, the pressure block 5, and the guide block 6. The guide block 6 moves downward relative to the deep groove ball bearing 7, and the deep groove ball bearing 7 applies a force that causes the guide block 6 to move horizontally. The telescopic spring 8 applies a force that causes the mounting base 4 to move in the opposite direction. After the guide block 6 abuts against the extension arm 30 and stops its horizontal movement, the guide block 6 and the mounting base 4 remain in a stable position and move vertically downward, while the pressure block 5 presses down vertically. When the piston rod of cylinder 2 extends upward, the sliding plate 3 moves upward, and the mounting base 4 moves upward along with the pressure block 5 and the guide block 6. The guide block 6 abuts against the deep groove ball bearing 7 during the upward movement, and the guide block 6 moves horizontally along with the mounting base 4 during the upward movement, thereby compressing the telescopic spring 8 and causing the pressure block 5 to also move horizontally during the upward movement.

[0021] Further improvements, such as Fig. 1 and Fig. 2 As shown, the guide block 6 includes an inverted L-shaped connecting part 61 connected to the bottom of the mounting base 4 and a bent foot 62 bent towards the sliding plate 3 at the bottom end of the connecting part 61. The guide slope 60 is the top surface of the bent foot 62. The horizontal part of the connecting part 61 is installed at the bottom of the mounting base 4, and the side wall of the vertical part of the connecting part 61 abuts against the right end of the extension arm 30 during the downward movement. At this time, the bottom end of the connecting part 61 is bent into a bent foot 62 on both sides. The two bent feet 62 are located on the front and rear sides of the lower end of the connecting part 61. The cylinder 2 is located below the space enclosed by the two bent feet 62. A deep groove ball bearing 7 is provided on the base 1 corresponding to each bent foot 62. The two deep groove ball bearings 7 correspond to the two bent feet 62.

[0022] Further improvements, such as Fig. 1 and Fig. 2As shown, on both sides of the mounting base 4 parallel to the sliding direction of the mounting base 4, there are L-shaped horizontal extension feet 40 extending downwards on the side corresponding to the sliding plate 3. The two extension feet 40 are located at the left ends of the front and rear side walls of the mounting base 4, with the horizontal part of the extension feet 40 facing to the right. The upper part of the sliding plate 3 is located between the two extension feet 40. On the side wall of the extension arm 30, there are two extension blocks 31 corresponding to the horizontal ends of the two extension feet 40. The front extension block 31 is opposite to the front extension foot 40, and the rear extension block 31 is opposite to the rear extension foot 40. Two telescopic springs 8 are provided and are correspondingly arranged between the two extension feet 40 and the two extension blocks 31. One telescopic spring 8 is arranged between the front extension block 31 and the extension foot 40, and the other telescopic spring 8 is arranged between the rear extension block 31 and the extension foot 40. The installation structure of the telescopic spring 8 is such that spring mounting holes 34 for installing the telescopic spring 8 are provided on the opposing surfaces between the horizontal end of the extension foot 40 and the extension block 31, which prevents the telescopic spring 8 from falling off the extension block 31 and the extension foot 40.
