Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to a buffer device for a mechanical weighing equipment. Background Art

[0002] In the field of mechanical manufacturing, in order to systematically understand the produced parts, overall equipment, etc., and facilitate the hoisting, moving, and transportation of parts and equipment, it is necessary to weigh the weight of the equipment and parts, and select appropriate transportation vehicles, lifting rings and other equipment according to the quality of the parts and equipment.

[0003] The existing mechanical weighing equipment does not have an ideal buffering effect. When a heavy equipment or part directly drops onto the weighing platform, it is easy to impact the quality sensor. Prolonged use affects the weighing accuracy and there is a risk of directly damaging the sensor. Therefore, when the weighing equipment is subjected to a strong impact, the weighing platform should slowly descend to avoid directly impacting the sensor, so as to achieve a buffering and protecting effect. Summary of the Utility Model

[0004] The utility model aims at the defects in the prior art and provides a buffer device for a mechanical weighing equipment.

[0005] The utility model is realized by the following technical solutions:

[0006] A buffer device for a mechanical weighing equipment, comprising a base, a weighing platform, an upper contact frame, a surrounding ring, a support frame, a sensor, a telescopic rod, a pressure-bearing mechanism, a support rod and a display. The weighing platform is arranged on the top of the base. The upper contact frame is arranged inside the top of the weighing platform. The surrounding ring is arranged on the upper surface of the base. The support frame is arranged inside the surrounding ring. The sensor is arranged on the top of the support frame. The telescopic rod and the pressure-bearing mechanism are arranged on the upper surface of the base. The support rod is arranged outside the surrounding ring. The display is arranged on the top of the support rod. The pressure-bearing mechanism comprises a bottom plate, a packaging cover and a filler. The bottom plate is fixedly connected with the upper surface of the base. The packaging cover is arranged on the upper surface of the base. The filler is arranged inside the packaging cover.

[0007] In a preferred embodiment of the utility model, the packaging cover is made of high-elastic rubber and the filler is a non-Newtonian fluid;

[0008] When the non-Newtonian fluid filler inside the packaging cover is subjected to a strong impact, the viscosity of the non-Newtonian fluid inside it increases short-term, so as to bear a large impact, and the viscosity decreases after the impact ends, causing the weighing platform to descend, so that the sensor can weigh the quality of the parts.

[0009] In a preferred embodiment of the utility model, a fixed sleeve is arranged inside the top of the weighing platform, and the telescopic end of the telescopic rod is fixedly connected with the bottom of the fixed sleeve inside the top of the weighing platform;

[0010] The main function of the telescopic rod is to assist the pressure-bearing mechanism to reset and lift it after weighing parts or equipment, so as to facilitate bearing impact again.

[0011] In a preferred embodiment of the present invention, the upper contact frame is arranged outside the top of the sensor, and a gap of 5 mm - 15 mm is formed between the contact surface of the upper contact frame and the sensor;

[0012] The gap between the upper contact frame and the sensor mainly provides sufficient buffer space when the weighing platform is impacted, and provides sufficient distance for the pressure-bearing mechanism to be instantaneously stressed.

[0013] In a preferred embodiment of the present invention, in the pressure-bearing mechanism, the top of the packaging cover contacts the inner side of the bottom of the weighing platform.

[0014] The beneficial effects of the present invention are:

[0015] The buffer device of this mechanical weighing equipment is mainly used for weighing large mechanical parts and equipment. When the parts or equipment contact the weighing platform of the weighing device instantaneously, it will strongly impact the sensor. However, there is non-Newtonian fluid inside the pressure-bearing mechanism of this weighing equipment. When it is strongly impacted, the viscosity of the internal non-Newtonian fluid filler instantaneously increases to bear the impact, so that the weighing platform slowly descends and contacts the sensor, avoiding strong impact, thereby protecting the weighing equipment.

[0020] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined. The directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0021] As Figures 1-3 shown, a buffer device for a mechanical weighing device includes a base 1, a weighing table 2, an upper contact frame 3, a retaining ring 4, a support frame 5, a sensor 6, a telescopic rod 7, a pressure-bearing mechanism 8, a support rod 9, and a display 10. The weighing table 2 is arranged on the top of the base 1, the upper contact frame 3 is arranged inside the top of the weighing table 2, the retaining ring 4 is arranged on the upper surface of the base 1, the support frame 5 is arranged inside the retaining ring 4, the sensor 6 is arranged on the top of the support frame 5, the telescopic rod 7 and the pressure-bearing mechanism 8 are arranged on the upper surface of the base 1, the support rod 9 is arranged outside the retaining ring 4, and the display 10 is arranged on the top of the support rod 9. The pressure-bearing mechanism 8 includes a bottom plate 81, a packaging cover 82, and a filler 83. The bottom plate 81 is fixedly connected to the upper surface of the base 1, the packaging cover 82 is arranged on the upper surface of the base 1, and the filler 83 is arranged inside the packaging cover 82.

[0022] Specifically, the material of the packaging cover 82 is high-elastic rubber, the filler 83 is a non-Newtonian fluid, a fixed sleeve is arranged inside the top of the weighing table 2, the telescopic end of the telescopic rod 7 is fixedly connected to the bottom of the fixed sleeve inside the top of the weighing table 2, the upper contact frame 3 is arranged outside the top of the sensor 6, and a gap of 5 mm - 15 mm is formed between the contact surfaces of the upper contact frame 3 and the sensor 6. In the pressure-bearing mechanism 8, the top of the packaging cover 82 contacts the inner side of the bottom of the weighing table 2.

[0023] In this embodiment, when weighing a part or a device, a hoisting device places the part to be weighed on the upper surface of the weighing table 2. At this time, the part or the device impacts the weighing table 2, and the instantaneous impact acts on the filler 83 in the packaging cover 82 of the pressure-bearing mechanism 8. Since the filler 83 is a non-Newtonian fluid, its viscosity instantaneously increases when subjected to an external force, thereby achieving a supporting effect. After the impact, the viscosity of the filler 83 decreases, causing the packaging cover 82 to collapse and expand, so that the weighing table 2 slowly descends. The upper contact frame 3 at its bottom acts on the surface of the sensor 6 on the top of the support frame 5, and the part or the device is weighed through the sensor 6, and its reading will be displayed on the display 10. The non-Newtonian fluid filler 83 in the pressure-bearing mechanism 8 effectively avoids the impact on the sensor 6 caused by the instantaneous descent of the weighing table 2, thereby achieving the effect of protecting the sensor 6 and ensuring the weighing accuracy.

[0024] Further, after weighing is completed, the telescopic rod 7 installed inside the base 1 and located outside the pressure-bearing mechanism 8 lifts the weighing platform 2. During this process, the packaging cover 82 is slowly lifted, and the filler 83 inside it is slowly shaped to enable it to withstand impacts again. Since the spring contraction amount inside the telescopic rod 7 is constant, that is, the distance between the upper contact frame 3 and the sensor 6, and the pressure required to contract the spring is also a fixed value, the weight reduction during weighing can be compensated according to the spring parameters inside the telescopic rod 7 to ensure weighing accuracy.

[0025] It should be noted that the parts not involved in the present utility model are the same as or can be implemented by the prior art; various drives in the present utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in cooperation with connecting rods, guide rods, etc., and are not limited to the descriptions in the specification and the structures in the drawings.

[0026] In the description of the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "set", "provided with", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] The above-described embodiments only represent several implementation manners of the present utility model, and the descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
