[0003] In the prior art, existing clamping fixtures typically use a multi-point independent clamping structure to clamp the display housing. Although this can achieve stable clamping, each independent clamping structure requires a separate cylinder drive, which not only makes the equipment complex and costly, but also results in asynchronous actions during the clamping process, low operating efficiency, and difficulty in meeting the needs of efficient assembly.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a display housing positioning and clamping fixture that can simultaneously clamp multiple points and improve assembly efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution: a display housing positioning and clamping fixture, comprising a base, a support plate, a push-pull drive mechanism, a push-pull plate, a slide, a clamping arm fixing seat, a swing clamping arm, and a pressure roller; The support plate is disposed on the base and is used to support and fix the display housing.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 5 As shown, this utility model embodiment provides a monitor housing positioning and clamping fixture, including a base 1, a support plate 2, a push-pull drive mechanism 3, a push-pull plate 4, a slide 5, a clamping arm fixing seat 6, a swinging clamping arm 7, and a pressure roller 8. The support plate 2 is disposed on the base 1 and is used to support and fix the monitor housing. The clamping arm fixing seat 6 is located on both sides of the support plate 2. The bottom of the swinging clamping arm 7 is swayably connected to the clamping arm fixing seat 6 via a rotating shaft. The pressure roller 8 is disposed on the top of the swinging clamping arm 7 and is used to abut and press against the monitor housing as the swinging clamping arm 7 swings. The support plate 2 is provided with a sliding groove 20, and the slide 5 is slidably connected to the sliding groove 20. One end of the slide 5 is connected to a first connecting block. 51 is connected to the bottom of the swing clamp arm 7. The swing clamp arm 7 is used to swing around the rotating shaft as the slide block 5 moves. The bearing plate 2 is provided with a push-pull groove 21 in the middle. The push-pull plate 4 is located in the push-pull groove 21 and can slide back and forth along the extension of the push-pull groove 21. The end of the slide block 5 away from the swing clamp arm 7 is provided with a slide rod 52. The bottom of the push-pull plate 4 is provided with an inclined groove 40. The slide rod 52 is located in the inclined groove 40. The slide rod 52 is used to drive the slide block 5 to slide back and forth along the extension direction of the slide groove 20 as the push-pull plate 4 moves. The push-pull drive mechanism 3 is provided on the side of the base 1 and connected to the push-pull plate 4. The push-pull drive mechanism 3 is used to drive the push-pull plate 4 to move. When it is necessary to position and clamp the monitor housing, the push-pull drive mechanism 3 can drive the push-pull plate 4 to move linearly back and forth along the extension direction of the push-pull groove 21. Since the bottom of the push-pull plate 4 is provided with a slanted groove 40, which cooperates with the slide rod 52 at the end of the slide block 5, when the push-pull plate 4 moves forward or backward, the position change of the slanted groove 40 relative to the slide rod 52 will generate a lateral component force, thereby driving the slide block 5 to slide synchronously along the direction of the slide groove 20. The slide block 5 is connected to the bottom of the swing clamping arm 7 through the first connecting block 51, thereby driving the swing clamping arm 7 to swing around the rotating shaft. When the swing clamping arm 7 swings downward, the pressure roller 8 can gradually press against the outer surface of the monitor housing to achieve clamping of the monitor housing; conversely, when the push-pull plate 4 returns, the swing clamping arm 7 swings upward under the drive of the slide block 5, and the pressure roller 8 leaves the housing, thereby achieving release. The entire clamping process is compact and has a short transmission path, which not only effectively improves the synchronization of the clamping process, but also simplifies the operation steps of the fixture, thereby achieving efficient clamping of the monitor housing.

[0021] like Figure 2As shown, the push-pull drive mechanism 3 further includes a push-pull cylinder 31, a moving plate 32, and a slide rail assembly 33. The push-pull cylinder 31 is located on the base 1 at the side end of the bearing plate 2. The movable end of the push-pull cylinder 31 is connected to the moving plate 32. The slide rail assembly 33 is disposed on the base 1 and connected to the moving plate 32. The side end of the moving plate 32 is connected to the push-pull plate 4 through a second connecting block 321. The push-pull cylinder 31 can push the moving plate 32 to move linearly in the horizontal direction. The slide rail assembly 33 can improve the movement stability of the moving plate 32 and prevent the moving plate 32 from shifting position during movement.

[0022] like Figure 2 As shown, the base also includes a first limiting rod 11 and a second limiting rod 12. The first limiting rod 11 and the second limiting rod 12 are respectively disposed on the front and rear sides of the base 1. The first limiting rod 11 is used to limit and abut against the push-pull plate 4, and the second limiting rod 12 is used to limit and abut against the moving plate 32. The first limiting rod 11 and the second limiting rod 12 can limit the stroke range of the push-pull plate 4 to prevent excessive movement of the push-pull plate 4 from causing mechanical interference damage.

[0023] like Figure 2 and Figure 4 As shown, the base 1 is further provided with a vertically upward positioning rod 13 at its corner. The positioning rod 13 is used to limit the connection with the positioning hole of the display housing to prevent the display housing from slipping and causing misalignment during assembly.

[0024] like Figure 1 and Figure 2 As shown, it further includes an upper cover plate 22, which is connected to the top of the support plate 2. The upper cover plate 22 is used to close the push-pull groove 21, thereby preventing foreign objects from entering the push-pull groove 21, extending the service life of the equipment, and avoiding mechanical failure caused by interference with foreign objects.

[0025] like Figure 2 As shown, the top surface of the support plate 2 is provided with a protrusion 23. The horizontal height of the protrusion 23 is greater than the horizontal height of the upper cover plate. This arrangement allows the display housing to contact the protrusion 23 when placed, thereby avoiding interference and jamming between the display housing and the upper cover plate 22.

[0026] Furthermore, the pressure roller 8 is made of rubber. This design can prevent scratches or indentations on the surface of the monitor housing. In addition, the rubber pressure roller 8 has a certain anti-slip performance, which effectively improves the pressing stability of the monitor housing.

[0027] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
