Description

Technical Field

[0001] This utility model relates to the field of refrigerator processing technology, and in particular to a tapping fixture for refrigerator bottom plates. Background Technology

[0002] Refrigerators are an indispensable appliance in modern life. They are refrigeration devices that maintain a constant low temperature, and are consumer products that keep food or other items at a constant low temperature. The refrigerator contains a compressor, an ice maker, and a cabinet or box for freezing ice; it is a storage box with a refrigeration unit.

[0003] During the production of refrigerators, various metals need to be drilled to assemble them into a complete device with screws and other components. Tapping is one such drilling process. Tapping, also known as thread tapping, is the process of creating threads on an object using a specialized tapping device. Generally, tapping machines are a common type of equipment. There are many types of tapping equipment, but the basic principle is that a motor drives the tapping head to rotate at high speed and move linearly, thereby drilling threaded holes on the surface of the workpiece.

[0004] With the automation of refrigerator production, most tapping processes have also become streamlined operations. However, refrigerator base plates, due to their numerous bends and "L" or even "S" shaped structures, are difficult to secure with ordinary clamps, hindering automated tapping. Currently, tapping refrigerator base plates requires manual assistance to press and hold the sides to be drilled in place on the tapping machine. This manual method undoubtedly reduces production efficiency and is also insufficient in terms of processing accuracy and safety. Therefore, a better tapping clamp is needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a refrigerator bottom plate tapping fixture, which solves the problems of low efficiency, poor accuracy, and low safety factor caused by the need for manual assistance in fixing the bottom plate during tapping.

[0006] According to an embodiment of this utility model, a refrigerator bottom plate tapping clamp includes a base, a support platform disposed on the base, and a sliding device disposed on one side of the support platform. The support platform is a vertically arranged strip structure. A hollow groove is provided on the top surface of the support platform near the sliding device. The sliding device includes a slide rail and a slider disposed above the slide rail. The slide rail is parallel to the support platform. An mounting plate is fixedly disposed above the slider. A baffle is disposed on the top of the mounting plate near the support platform. The baffle is parallel to the side of the support platform. A clamping member is disposed on the side of the mounting plate away from the support platform. The clamping member is disposed towards the baffle to fix the refrigerator bottom plate located between the clamping member and the baffle.

[0007] Furthermore, the lower part of the side of the support platform near the guide rail is provided with a recess, and the mounting plate extends toward the recess so that the baffle is precisely embedded in the recess, that is, the side of the baffle near the clamping member corresponds to the side position of the support platform.

[0008] Furthermore, the mounting plate is also provided with a placement platform, the clamping member is located on the top of the placement platform, and there is a gap between the end of the placement platform near the support platform and the baffle to form a limiting groove.

[0009] Furthermore, the clamping member includes two telescopic rods arranged side by side, the telescopic rods being placed horizontally and perpendicular to the baffle.

[0010] Furthermore, a pressing plate is fixedly connected to one end of the telescopic rod near the baffle. The pressing plate is a disc structure parallel to the side of the baffle.

[0011] Furthermore, a ranging device is also provided on the top of the support platform near the hollow groove. The ranging device is vertically facing the top surface of the support platform, and the projection of the ranging device on the top surface of the support platform is located outside one end of the hollow groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model features a support platform and a sliding device arranged side by side. The support platform has a higher top and a perforated groove for tapping the bent edge of the refrigerator base plate. The refrigerator base plate is vertically fixed by clamping components and a baffle, ensuring it is vertically aligned with the baffle. The bent edge extends through the baffle to the top of the support platform. As the refrigerator base plate moves along the guide rail with the mounting plate, its bent edge slides horizontally from the top of the support platform. Tapping stops when it reaches the perforated groove. After processing, the fixing is released, and the refrigerator base plate can be removed. This utility model automates the fixing, clamping, and movement of the refrigerator base plate, eliminating the need for manual placement and clamping. This significantly improves production efficiency, increases processing accuracy, and avoids potential safety hazards associated with manual operation. Attached Figure Description

[0017] The dashed line represents the refrigerator base plate to be processed. Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 As shown in the figure, this utility model embodiment proposes a refrigerator bottom plate tapping fixture, including a base 1, a support platform 2 disposed on the base 1, and a sliding device disposed on one side of the support platform 2. In this utility model embodiment, a tapping machine is correspondingly disposed on one side of the support platform 2, such that the tapping head of the tapping machine is vertically downward and aligned with the top surface of the support platform 2.

[0020] The support platform 2 is a vertically arranged strip structure. A slot 21 is provided on the top surface of the support platform 2 near the sliding device, allowing the tapping head to pass through the workpiece and extend into the slot 21 for drilling. The size of the slot 21 is much smaller than the size of the bent edge of the refrigerator bottom plate that needs to be drilled, so that the bent edge of the refrigerator bottom plate can be effectively supported during the tapping process and will not deform.

[0021] The sliding device includes a slide rail and a slider 31 disposed above the slide rail. In this embodiment, the slide rail and slider 31 adopt a ball screw guide rail 3 structure, which can automatically control the slider 31 to move along the slide rail. Its specific structure is existing technology and will not be described in detail here. The slide rail is parallel to the support platform 2. A mounting plate 4 is fixedly disposed above the slider 31. A baffle 5 is disposed on the top of the mounting plate 4 near the support platform 2. The baffle 5 is parallel to the side of the support platform 2. A clamping member is disposed on the side of the mounting plate 4 away from the support platform 2. The clamping member is disposed towards the baffle 5 to fix the refrigerator bottom plate located between the clamping member and the baffle 5.

[0022] like Figure 2 As shown, in this embodiment, the lower part of the side of the support platform 2 near the guide rail 3 is provided with a recessed portion. The mounting plate 4 extends toward the recessed portion, so that the baffle 5 is precisely embedded in the recessed portion. That is, the side of the baffle 5 near the clamping member corresponds to the side position of the support platform 2. In this way, when the refrigerator bottom plate is vertically set close to the baffle 5, it is also set close to the support platform 2. Then, the bent edge of the refrigerator bottom plate located at the top does not need to pass through the top of the baffle 5 to extend directly to the top surface of the support platform 2, so that the narrow bent edge will not be hindered by the baffle 5 and affect its tapping process.

[0023] In a further embodiment, the mounting plate 4 is also provided with a placement platform 6, and the clamping member is located on top of the placement platform 6. A gap is left between the end of the placement platform 6 near the support platform 2 and the baffle 5 to form a limiting groove. In this way, the partially "S"-shaped refrigerator bottom plate can place the bent edge at the other end away from the side that needs to be tapped into the limiting groove, and then be fixed with the clamping member to make it more secure.

[0024] In this preferred embodiment, the clamping component includes two telescopic rods 7 arranged side by side, the telescopic rods 7 being horizontally placed and perpendicular to the baffle 5. A pressing plate 71 is also fixedly connected to one end of the telescopic rod 7 near the baffle 5, the pressing plate 71 being a disc structure parallel to the side of the baffle 5. After the refrigerator base plate is placed, the telescopic rods 7 extend and press the refrigerator base plate firmly onto the baffle 5 through the pressing plate 71, thus completing the clamping and fixing process.

[0025] In addition, a ranging device 8 is provided on the top of the support platform 2 near the hollow groove 21 in this utility model. In this embodiment, an infrared rangefinder is used. The ranging device 8 is vertically oriented towards the top surface of the support platform 2, and the projection of the ranging device 8 on the top surface of the support platform 2 is located outside one end of the hollow groove 21. Because the refrigerator bottom plate is moved by the slider 31 during operation, the bent edge of the refrigerator bottom plate slides horizontally across the top of the support platform 2. Since the area to be tapped is a recessed part, its height is lower than the surface of the bent edge. Therefore, it is detected when passing the ranging device 8. The slider 31 stops after sliding a fixed distance, so that the tapping area is exactly above the hollow groove 21. At this time, precise tapping can be achieved, thereby further improving the degree of automation.

[0026] Finally, it should be noted that the above 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 preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
