Technical Field

The utility model relates to the technical field of refrigerator door panel processing and clamping, in particular to a refrigerator door panel clamping mechanism.

Background technique

During the process of cutting, polishing and painting the refrigerator door panels, it is usually necessary to place the door panels on a smooth work surface for processing, and sometimes in order to prevent the door panels from slipping and affecting the processing progress, it is usually necessary to cooperate with a corresponding clamping mechanism.

The patent number is CN201820547734.5 and its name is "A multifunctional workbench for door panel processing". It includes a workbench and a supporting base. L-shaped fixing plates are arranged on both sides above the workbench. An adjusting nut is welded on the middle part of the upper end of the L-shaped fixing plate, and an adjusting screw is screwed in the adjusting nut. A pressure plate is rotatably connected to the lower end of the adjusting screw. The outer side of the pressure plate is also slidably connected to the inner side wall of the L-shaped fixing plate. A second L-shaped sliding rod is also welded in the middle part of the outer side of the L-shaped fixing plate. Longitudinal adjustment plates are fixedly connected to both sides of the workbench. A transverse adjustment plate is arranged above the longitudinal adjustment plate, and strip holes are opened on the transverse adjustment plate and the longitudinal adjustment plate. A first L-shaped sliding rod is welded on both ends of the transverse adjustment plate. A first locking nut is tightly screwed on the bottom end of the first L-shaped sliding rod, and a second locking nut is tightly screwed on the bottom end of the second L-shaped sliding rod. The utility model solves the problem that the current door panel processing workbench lacks a convenient clamping mechanism and the clamping position is not easy to adjust.

Although the above patent application can clamp and fix door panels of different sizes by adjusting the positions of the two clamping mechanisms, the workbench in the application cannot drive the door panel to rotate. In this way, the door panel needs to be rotated manually or the processing staff needs to rotate it themselves to cut, polish or paint different parts of the door panel. This will cause inconvenience when the workbench is used for auxiliary processing. Therefore, the utility model proposes a refrigerator door panel clamping mechanism to solve the problems existing in the prior art.

The first motor 2 on the base plate 1 drives the rotating column 3 on the base plate 1 to rotate through a gear set, a door panel clamping workbench 4 is installed on the rotating column 3, and a limit member 4.1 is fixedly connected to the door panel clamping workbench 4. A screw motor 5 is arranged on one side of the door panel clamping workbench 4, a groove is opened on the door panel clamping workbench 4, a slider 6 is slidably connected in the groove of the door panel clamping workbench 4, a roller is arranged at the bottom of the slider 6, the screw of the screw motor 5 is fixedly connected to the slider 6, the slider 6 slides toward the limit member 4.1 to clamp the refrigerator door panel, and an inclined guide rod 4.2 is fixedly connected to the door panel clamping workbench 4 through a connecting rod.

Compared with the prior art, the utility model provides a refrigerator door panel clamping mechanism, the first motor 2 with the main gear 2.1 rotates, the main gear 2.1 on the first motor 2 will drive the sub-gear 3.1 on the rotating column 3 to rotate, so that the rotating column 3 rotates, the rotation of the gear 2.1 and the gear 3.1 can adjust the speed of the door panel clamping workbench 4 to adjust the angle of the refrigerator door panel, the clamping workbench 4 fixed on the rotating column 3 will rotate with the rotating column 3, the screw motor 5 on the door panel clamping workbench 4 will drive the movement of the screw, the screw pushes the slider 6 to move, the slider 6 abuts the refrigerator door panel against the limiter 4.1, so that the refrigerator door panel is fixed in the horizontal direction. The refrigerator door panel is fixed as a whole on the door panel clamping workbench and rotates as a whole when cutting and other operations are required, which can adjust the orientation of the refrigerator door panel and facilitate processing operations.

As a preferred technical solution of this embodiment, referring to Fig. 1-2, the rotating column 3 is rotatably connected to the bottom plate 1 via a bearing, which can prevent the bottom plate 1 from rotating during the rotation of the gear set.

As a preferred technical solution of this embodiment, the elastic telescopic rod 7 includes an inner rod, a sleeve rod and a compression spring. The sleeve rod is slidably mounted on the inner rod. A compression spring is provided between the inner rod and the sleeve rod. One end of the compression spring is fixedly connected to the sleeve rod, and the other end is fixedly connected to the inner rod. The elastic telescopic rod 7 can make it more convenient to fix the door panel.

As a preferred technical solution of this embodiment, the gear set includes a main gear 2.1 and a sub gear 3.1, the main gear 2.1 is coaxially fixedly connected to the rotating shaft of the first motor 2, and the sub gear 3.1 is coaxially fixedly connected to the rotating column 3, the main gear 2.1 is meshed with the sub gear 3.1, and the diameter of the main gear 2.1 is smaller than the diameter of the sub gear 3.1, thereby realizing reduction transmission.

As a preferred technical solution of this embodiment, a ball bearing is provided at the bottom of the slider 6 to reduce the wear of the slider 6 and the internal groove of the door panel clamping workbench 4 during movement, and can make the sliding process of the slider 6 smoother.

In another embodiment provided by the utility model, a cross plate is fixedly connected to the top of the slider 6, and an elastic telescopic rod 7 is vertically slidably connected to the cross plate. A spring 8 is arranged between the cross plate and the elastic telescopic rod 7, and the elastic force of the spring 8 acts upward on the elastic telescopic rod 7, and the top of the elastic telescopic rod 7 is slidably abutted with the guide rod 4.2. In this scheme, the screw motor 5 drives the slider 6 to slide along the groove, and the slider 6 drives the elastic telescopic rod 7 to move synchronously through the cross plate, during which the top of the elastic telescopic rod 7 abuts against the inclined guide rod 4.2, so that the elastic telescopic rod 7 slides downward relative to the cross plate until the bottom of the elastic telescopic rod 7 abuts against the upper surface of the refrigerator door panel. At this time, if the slider 6 has not abutted against the side of the refrigerator door panel, as the slider 6 continues to slide, the elastic telescopic rod 7 will shrink until the slider 6 abuts against the side of the refrigerator door panel, and the elastic telescopic rod 7 also remains abutted against the upper surface of the refrigerator door panel. In this way, during the process of horizontally clamping the refrigerator door panel, the slider 6 can cooperate with the guide rod 4.2 through the elastic telescopic rod 7 to achieve downward pressure on the top of the refrigerator door panel, thereby achieving simultaneous fixation of the refrigerator door panel in the horizontal direction and the vertical direction. The refrigerator door panel can be clamped in multiple directions, which greatly increases the firmness of the clamping of the refrigerator door panel during the clamping process, thereby avoiding the phenomenon of loose clamping of the refrigerator door panel when operating the refrigerator door panel. This is a door panel clamping mechanism with good clamping effect, convenient operation and very practical.

As a preferred technical solution of this embodiment, installing a rubber pad at the bottom of the elastic telescopic rod 7 can increase the firmness of the connection between the elastic telescopic rod 7 and the refrigerator door panel, and can also reduce damage to the refrigerator door panel during the clamping process.

The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
