Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliance hardware clamping devices, in particular to a fastening device for kitchen appliance hardware processing. Background Art

[0002] In modern kitchens, electrical appliances have become an indispensable part, such as rice cookers, microwave ovens, ovens, etc. The performance and durability of these appliances depend largely on the processing quality of their hardware. As an important part of kitchen appliances, the processing accuracy and stability of hardware are directly related to the overall performance and safety of the appliances. In the processing of kitchen appliance hardware, fastening is a crucial link. The main function of the fastening device is to fix the hardware on the processing equipment to ensure that the position of the hardware is stable and does not deform during the processing.

[0003] For example, the Chinese authorized patent "A fastening device for hardware processing" with announcement number CN212470576U includes a base; two plywoods are arranged on the surface of the base, and extension plates are extended at both ends of the two plywoods away from each other on one side, and through holes are arranged on the surface of the extension plates, and a plurality of grooves are arranged on the circumferential side of the through holes, and a rotating rod is arranged between the two extension plates, and a plurality of protrusions are arranged at the positions of the rotating rod corresponding to the grooves; the two ends of the rotating rod pass through the through holes and the protrusions are fixed by engagement with the grooves; a cross plate is horizontally fixed at the upper and lower ends of the two plywoods away from each other, and a push plate is vertically connected to the other end of the cross plate, and a screw is horizontally fixed at the center position of the other side of the push plate; two baffles are fixedly arranged on the surface of the base, and the two baffles are arranged on the side of the two plywoods away from each other, and screw holes are arranged on the surfaces of the two baffles, and internal threads are arranged in the screw holes.

[0004] Although the above-mentioned prior art can realize the processing and fastening of kitchen appliance hardware, the fastening structure is relatively complicated and cannot simplify the operation process under the premise of ensuring the firmness of clamping. In addition, the control of clamping force during the fastening process is poor, which at best reduces the fastening effect and at worst causes damage to the hardware. Therefore, it does not meet the existing needs. In this regard, we propose a fastening device for processing kitchen appliance hardware. Utility Model Content

[0005] The purpose of the utility model is to provide a fastening device for processing kitchen appliance hardware, so as to solve the problem of how to simplify the operation process under the premise of ensuring the firmness of clamping proposed in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fastening device for processing kitchen appliance hardware, comprising a base, wherein a fastening platform is provided at the middle position of the upper end surface of the base; and further comprising:

[0010] Preferably, a servo motor is installed below the interior of the base, and a stud is installed on the output shaft of the servo motor. The stud extends into the interior of the lifting column, and the stud is threadedly matched with the lifting column.

[0011] Preferably, a mounting rod is fixedly provided on the inner side of the upper end of the clamping arm, an adjusting rod is installed inside the mounting rod, and the adjusting rod is slidably connected to the mounting rod, a plurality of equidistantly distributed positioning holes are provided inside the adjusting rod, a positioning pin is provided on one side of the upper end of the mounting rod, and the positioning pin is adapted to the positioning hole.

[0012] Preferably, a clamping head is installed on one side of the adjusting rod, and the clamping head and the adjusting rod are slidingly limited, a pressure sensor is installed between the clamping head and the adjusting rod, and the fixed end of the pressure sensor is fixed to the adjusting rod, the signal output end of the pressure sensor is connected to a processor, and the output end of the processor is connected to a servo motor.

[0013] Preferably, the side of the clamping head for contacting the hardware is made of rubber material.

[0014] Preferably, an empty groove is reserved on the upper end surface of the base for the clamping arm to swing.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model uses an arm body with a multi-link to fasten the hardware. The staff can place the hardware on the upper end surface of the fastening platform, and turn on the servo motor. The output shaft drives the stud to rotate. Under the friction between the external thread and the screw hole in the lifting column, the lifting column is guided by the limiting slide groove to move downward, so that the adjustment seat pulls the adjustment arm downward. One end of the clamping arm and the adjustment arm are respectively positioned on the base through the first rotating shaft and the third rotating shaft. The connecting arm is used to keep the adjustment arm parallel to the clamping arm during the movement, and then the tilt is converted into the horizontal. The clamping head at one end is used to fix the hardware. The structure is simple to operate. The loosening and clamping movements of the clamping arm can be realized by controlling the lifting and lowering of the adjustment seat. The fixing effect is good, and the stability of the hardware processing process is ensured.

[0017] 2. The utility model provides a pressure sensor inside the adjusting rod. As the clamping head contacts the hardware, a reaction force is generated on the clamping head, causing it to apply pressure to the pressure sensor. The pressure sensor can monitor the pressure in real time. When the pressure is lower than the set value, the servo motor is kept on to allow the clamping head to continue clamping the hardware. When the pressure reaches the set value, the servo motor is quickly turned off to avoid damage to the hardware due to excessive pressure. This mechanism can improve the protection of the hardware while improving the fastening effect of the hardware.

[0018] 3. The utility model is provided with an adjustable chuck, and the length of the clamping head can be adjusted according to the hardware of different specifications. It is only necessary to pull out the positioning pin to eliminate the limiting effect on the adjusting rod, and then the adjusting rod can be freely moved. After the movement, the positioning pin is inserted into the mounting rod and extended to the positioning hole of the adjusting rod, so that the adjusting rod can be fixed in position, ensuring the adaptability to different hardware.
