Description

Technical Field

[0001] The utility model relates to the technical field of grinding processing, in particular to an end face grinding device for processing the upper and lower pressing plates of a refrigerator. Background Art

[0002] The end face grinding device for processing the upper and lower pressing plates of a refrigerator is an automated device specially designed for end face grinding of the upper and lower pressing plates on the refrigerator production line. The upper and lower pressing plates of a refrigerator are important components in refrigerator manufacturing, usually used to fix and support the inner liner and heat insulation material of the refrigerator. This device can usually automatically complete the handling, positioning and grinding of the pressing plate, reducing manual intervention and improving production efficiency.

[0003] After the existing end face grinding device for processing the upper and lower pressing plates of a refrigerator finishes grinding the end face of the pressing plate, there may indeed be the following drawbacks, especially regarding temperature and safety issues. During the grinding process, due to the fast grinding speed and large frictional heat, the end face of the pressing plate is prone to high temperature. Especially when using a high-speed rotating grinding head or grinding disc for grinding, the heat will quickly accumulate on the pressing plate material. After grinding is completed, the temperature of the pressing plate may be relatively high, and the bottom end of the pressing plate is in contact with the workbench. If the operator directly touches it with their hands, it is very easy to cause burns. Even when using heat-insulating gloves, there is still a risk of burns. For this reason, we propose an end face grinding device for processing the upper and lower pressing plates of a refrigerator. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an end face grinding device for processing the upper and lower pressing plates of a refrigerator. The design of the ejection mechanism allows the operator not to directly touch the high-temperature pressing plate after grinding the refrigerator pressing plate, thus significantly reducing the risk of burns. Through the mechanical jacking method, the need for the operator to directly touch the pressing plate is avoided, and even the risk of using heat-insulating gloves is eliminated.

[0005] To solve the above technical problems, the utility model provides the following technical solution: An end face grinding device for processing the upper and lower pressing plates of a refrigerator, including a grinding device main body, a driving panel is arranged on the outer wall of the grinding device main body, a grinding head is arranged on the grinding device main body, a workbench is arranged on the grinding device main body, two groups of clamping members are symmetrically connected to the workbench, a clamping table is arranged on the workbench, an ejection mechanism is arranged in the clamping table, a refrigerator pressing plate is clamped above the clamping table by the two groups of clamping members, and the ejection mechanism jacks up the refrigerator pressing plate by rotation.

[0006] As a preferred technical solution of the utility model, the ejection mechanism includes a rotating member arranged in the clamping table and a jacking member movably connected to the rotating member.

[0007] As a preferred technical solution of the present utility model, the rotating member includes a rotating shaft rotatably connected to the inner wall of the clamping table, a lead screw connected to one end of the rotating shaft, an inner plate movably connected to the lead screw and arranged on the inner wall of the clamping table, and a rotating wheel connected to the outer end of the rotating shaft.

[0008] As a preferred technical solution of the present utility model, the rotating wheel drives the rotating shaft and the lead screw to rotate synchronously through rotation, and anti-slip lines are arranged on the outer wall of the rotating wheel.

[0009] As a preferred technical solution of the present utility model, two groups of thread patterns are symmetrically arranged on the lead screw, and the two groups of thread patterns are arranged in opposite directions, and a jacking member is connected to the lead screw.

[0010] As a preferred technical solution of the present utility model, the jacking member includes two sets of nuts threadedly connected to the lead screw, sliders with one end connected to the side wall of the nut and the other end slidably connected to the inner wall of the clamping table, hinge rods with one end hinged to the top of the nut, and a top plate hinged to the other end of the hinge rod.

[0011] As a preferred technical solution of the present utility model, two sets of hinge rods are symmetrically hinged to the top of each set of nuts, and each set of hinge rods is designed in an oval shape.

[0012] Compared with the prior art, the beneficial effects that the present utility model can achieve are:

[0013] 1.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following combines specific embodiments to further elaborate the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the present utility model. The experimental methods in the following embodiments, unless otherwise specified, are all conventional methods. The materials, reagents, etc. used in the following embodiments, unless otherwise specified, can all be obtained from commercial channels.

[0023] Embodiment:

[0024] As Figures 1-5 shown, an end - face grinding device for processing upper and lower pressing plates of a refrigerator includes a main body 1 of the grinding device. A driving panel 2 is arranged on the outer wall of the main body 1 of the grinding device. A grinding head 3 is arranged on the main body 1 of the grinding device. A workbench 4 is arranged on the main body 1 of the grinding device. Two groups of clamping members 6 are symmetrically connected to the workbench 4. A clamping table 5 is arranged on the workbench 4. An ejection mechanism 8 is arranged in the clamping table 5. A refrigerator pressing plate 7 is clamped by two groups of clamping members 6 above the clamping table 5. The ejection mechanism 8 jacks up the refrigerator pressing plate 7 by rotation;

[0025] The ejection mechanism 8 includes a rotating member disposed within the clamping table 5 and a jacking member movably connected to the rotating member. The rotating member includes a rotating shaft 81 rotatably connected to the inner wall of the clamping table 5, a lead screw 82 connected to one end of the rotating shaft 81, an inner plate 83 movably connected to the lead screw 82 and disposed on the inner wall of the clamping table 5, and a runner 88 connected to the outer end of the rotating shaft 81. The jacking member includes two sets of nuts 84 threadedly connected to the lead screw 82, a slider 85 having one end connected to the side wall of the nut 84 and the other end slidably connected to the inner wall of the clamping table 5, a hinge rod 86 having one end hinged to the top end of the nut 84, and a top plate 87 hinged to the other end of the hinge rod 86.

[0026] When the refrigerator pressing plate 7 becomes overheated after being polished by the grinding head 3 and the operator needs to jack up the refrigerator pressing plate 7, first rotate the runner 88. The runner 88 drives the rotating shaft 81 to rotate, and the rotating shaft 81 drives the connected lead screw 82 to rotate synchronously. The rotation of the lead screw 82 drives the two sets of nuts 84 threadedly connected thereto to move towards each other. The nuts 84 slide on the inner wall of the clamping table 5 through the sliders 85. The inner wall of the clamping table 5 is provided with sliding grooves corresponding to the sliders 85. While the two sets of nuts 84 move towards each other, they squeeze the four hinge rods 86 to jack up upwards. The four hinge rods 86 jack up the top plate 87 out of the clamping table 5. A notch is provided at the top end inside the clamping table 5, and 57 can be removed from the notch to jack up the refrigerator pressing plate 7 to complete the unloading.

[0027] It should be noted that the runner 88 drives the rotating shaft 81 and the lead screw 82 to rotate synchronously through rotation. This design ensures that when the operator rotates the runner 88, the rotating shaft 81 and the lead screw 82 can rotate simultaneously, which can maintain the synchronous movement of the mechanism, making the actions of the ejection mechanism coordinated. The synchronous rotation helps ensure that the refrigerator pressing plate 7 can be jacked up evenly and smoothly, avoiding uneven movement of the pressing plate caused by non-synchronization, which may lead to damage to the pressing plate or failure of the jacking. Anti-slip patterns are provided on the outer wall of the runner 88. The design of the anti-slip patterns increases the friction on the surface of the runner 88, making it not easy for the operator to slip when turning the runner 88 by hand, even if there is sweat or moisture on the hand.

[0028] Two sets of thread patterns are symmetrically provided on the lead screw 82, meaning that the two sets of nuts 84 can move towards each other, which can provide balanced force when jacking up the refrigerator pressing plate. The two sets of thread patterns are arranged in opposite directions. This design helps prevent the lead screw 82 from being distorted or offset during rotation, ensuring the accuracy and reliability of the jacking action. The lead screw 82 is connected to the jacking member. This design enables the ejection mechanism to effectively convert the rotational force into an upward thrust to complete the task of jacking up the pressing plate.

[0029] At the top of each lead screw nut 84, two hinge rods 86 are symmetrically hinged, which helps to maintain the balance during the jacking process and prevent the pressing plate from skewing or twisting during jacking. Each hinge rod 86 is designed in an oval shape. The oval-shaped hinge rod 86 can provide a larger contact area and a more uniform force distribution during the jacking process, reduce the local pressure on the pressing plate, and protect the pressing plate from damage.

[0030] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the first and second features not being in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0031] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
