Description

Technical Field

[0001] The invention relates to the technical field of hardness detection, in particular to a rubber product hardness detection device. Background Art

[0002] In the production of rubber products, different application scenarios have strict requirements on rubber hardness. Hardness testing equipment can accurately measure rubber hardness to ensure that the product meets relevant standards and customer requirements. By conducting regular hardness testing on rubber products on the production line, hardness fluctuations can be discovered in time, making it easier to take measures to adjust the production process, ensure product quality consistency and stability, and reduce the defective rate. During the use of rubber product hardness testing equipment, a pressure needle of a specified shape is pressed into the surface of the rubber product being tested under the pressure of a spring. When the pressure needle is pressed vertically into the rubber sample, the depth of pressure at the end of the pressure needle is inversely proportional to the hardness of the rubber. The internal structure of a spring-type pressure adjustment button is usually composed of an adjustment knob, a threaded rod, a spring fixing seat, a pressure spring, and a locating pin or a guide groove. The adjustment knob is usually located on the outside for user convenience. Its surface may have anti-slip textures and a threaded structure inside, which cooperates with the components below to achieve pressure adjustment. The threaded rod matches the thread of the adjustment knob. When the adjustment knob is rotated, the threaded rod will move up and down. The lower end of the threaded rod is connected to the spring fixing seat, which is used to fix one end of the spring. As the threaded rod moves up and down, the spring fixing seat will also move accordingly, thereby changing the degree of compression of the spring. The pressure spring is the core component that provides pressure. One end is fixed to the spring fixing seat, and the other end is usually connected to the components related to the pressure needle or pressure sensor. The pressure applied to the object being measured is changed by adjusting the compression of the spring; Press the indenter of specified shape vertically into the surface of rubber sample under certain pressure, and determine the hardness value according to the indentation depth. For thicker rubber samples, since there is more rubber material inside to resist the indentation of the indenter, a larger testing pressure is required to make the indenter reach the appropriate indentation depth, so as to accurately reflect the hardness characteristics of the rubber. For thinner rubber samples, under smaller pressure, the indenter may be pressed too deep or even penetrate the sample, and the hardness cannot be accurately measured. Therefore, a smaller testing pressure is required to make the indentation depth within a reasonable measurement range. For example, rubber samples with a thickness of less than 6mm should be tested with a smaller pressure, while rubber samples with a thickness of more than 10mm often require a larger pressure to make the test results accurate and reliable. A larger testing pressure is required when the rubber sample is thicker, and a smaller testing pressure is required when the thickness is thinner. During the rubber sample testing process, the thickness of the sample needs to be tested in advance, and the testing pressure needs to be manually adjusted according to the thickness. However, it is difficult to adjust the pressure very accurately manually. Different operators may have different understandings of pressure adjustment. Even for the same operator, it is difficult to adjust the pressure to a completely consistent and accurate value every time. Moreover, the operator needs to gradually adjust the pressure value based on experience and the thickness of the rubber sample. This process is relatively cumbersome, especially when testing a large number of rubber samples of different thicknesses. It will take a lot of time to adjust the pressure, which reduces the overall testing efficiency. Manual pressure adjustment requires operators to have rich experience and professional knowledge, and understand the approximate pressure range required for rubber of different thicknesses. Inexperienced operators may not be able to accurately judge and adjust the pressure, resulting in inaccurate test results, which increases the training cost and difficulty of operators. In addition, operators are prone to fatigue after long-term manual pressure adjustment operations, which may lead to operational errors, such as excessive or insufficient pressure adjustment. Frequent manual pressure adjustment will cause the pressure control components of the testing equipment, such as the pressure adjustment knob and pressure sensor, to be subjected to more friction and mechanical stress, which may easily cause these components to wear out prematurely, reducing the service life and performance stability of the equipment. Moreover, in cold weather, rubber becomes hard, and in hot weather, rubber becomes soft. Therefore, the temperature of the external environment will affect the hardness of the rubber, and errors will occur during the hardness testing process. For this reason, we propose a rubber product hardness testing device. Summary of the invention

[0023] The docking assembly 5 includes a gear five 51 meshingly connected to the gear three 47, and a rotating rod two 46 is fixed to the center of the gear five 51, a gear six 52 cooperating with the gear four 48 is fixed to the outer wall of the rotating rod two 46, a belt 56 is slidably connected to the outer wall of the rotating rod two 46, an insert ring 55 is movably connected to the tail of the rotating rod two 46, a socket 53 is fixed to the end face of the adjusting knob 42, and an insert ring 54 is provided on the side of the socket 53, and teeth cooperating with the socket 53 are fixed on the surface of the insert ring 54.

[0024] The switching assembly 6 includes a moving ring 61 which is slidably connected to the outer wall of the rotating rod 2 46 through a slip ring 68, and the outer wall of the moving ring 61 is sequentially distributed with a metal sheet 1 62, a metal sheet 2 63 and a metal sheet 3 64, the metal sheet 1 62, the metal sheet 2 63 and the metal sheet 3 64 are arranged alternately, and the sides of the metal sheet 1 62, the metal sheet 2 63 and the metal sheet 3 64 are sequentially provided with an electromagnet seat 1 65, an electromagnet seat 2 66 and an electromagnet seat 3 67, the outer wall of the insert ring 55 is fixed to the inner wall of the protective cover 41, and the inner wall of the insert ring 55 is provided with a metal sheet 1 65, an electromagnet seat 2 66 and an electromagnet seat 3 67. The sliding mouth of the electromagnet seat 1 66 and the electromagnet seat 3 67 is matched, and an elastic rope 69 is fixed on the side of the electromagnet seat 1 65, and the end face of the elastic rope 69 is fixed on the inner wall of the sliding mouth. The electromagnet seat 1 65, the electromagnet seat 2 66 and the electromagnet seat 3 67 are all composed of an electromagnet and a slide plate. The electromagnet is fixed on the surface of the slide plate, and the end face of the slide plate can slide inside the sliding mouth. The sliding mouth design facilitates the storage operation of the electromagnet seat 1 65, the electromagnet seat 2 66 and the electromagnet seat 3 67 when they are not needed, thereby preventing the electromagnet seat 1 65, the electromagnet seat 2 66 and the electromagnet seat 3 67 from affecting the movement of the movable ring 61.

[0025] When the gear switch three 34 is pressed, the controller controls the electromagnet in the electromagnet seat one 65 to be energized, and the electromagnet seat one 65 generates magnetism after being energized. Under the action of magnetism, the metal sheet one 62 moves in the direction close to the electromagnet seat one 65. At the same time, the electromagnet seat one 65 moves in the direction close to the metal sheet one 62. The elastic rope 69 is pulled by the electromagnet seat one 65 and is in a stretched and force-storing state. The metal sheet one 62 drives the moving ring 61 to move synchronously, and the moving ring 61 drives the rotating rod two 46 to move. The pulley on the side of the belt 56 close to the rotating rod two 46 slides horizontally on the surface of the rotating rod two 46 until the metal sheet one 62 and the electromagnet seat one 65 are attracted to each other, the gear four 48 is meshed with the gear six 52, and the rotating rod two 46 stops moving, so as to realize the switching operation of the fine-tuning gear, adapt to the sample with low thickness, and reduce the rotation accuracy of the adjusting knob 42. For example, rotating one degree increases the pressure of one scale, so as to realize the adjustment of the pressing accuracy of the pressing needle member 14 according to the sample thickness. When the gear switch 233 is pressed, the controller controls the electromagnet in the electromagnet seat 266 to be energized. After the electromagnet seat 266 is energized, magnetism is generated, so that the metal sheet 263 moves toward the direction close to the electromagnet seat 266. Under the action of magnetism, the two are close to each other, and the electromagnet seat 266 moves inside the slide until the electromagnet seat 266 fits with the metal sheet 263. The metal sheet 263 drives the rotating rod 246 to move until the gear 347 fits with the gear 51, so as to realize the switching operation of the medium-range adjustment gear, which is suitable for samples of medium thickness. For example, the adjustment knob 42 is rotated once to increase the pressure of two scales. When the electromagnet seat 266 is energized, the magnetism of the electromagnet seat 266 is released. Under the action of gravity, the electromagnet seat 266 moves down along the slide. When the gear switch 32 is pressed, the controller controls the electromagnet in the electromagnet seat 3 67 to be energized. Under the action of magnetism, the metal sheet 3 64 and the electromagnet seat 3 67 approach each other, driving the rotating rod 2 46 to move, so that the plug ring 54 is engaged with the inside of the socket 53, and the adjustment knob 42 and the rotating rod 2 46 are docked and locked. At this time, the meshing of the gear 2 44 and the gear 1 43 is released, and the adjustment knob 42 is rotated to synchronously drive the rotating rod 2 46 to rotate, thereby realizing the switching operation of the gear adjustment in a large range and increasing the rotation accuracy of the adjustment knob 42. For example, if it is rotated one degree, the pressure of three scales will be increased to adapt to samples with high thickness.

[0026] The gear switch one 32, the gear switch two 33 and the gear switch three 34 cooperate with the electromagnet seat one 65, the electromagnet seat two 66 and the electromagnet seat three 67 respectively. According to the trigger signals of the gear switch one 32, the gear switch two 33 and the gear switch three 34, the electromagnet seat one 65, the electromagnet seat two 66 and the electromagnet seat three 67 are energized respectively, and magnetism is generated after energization. Under the action of magnetism, the metal sheet one 62, the metal sheet two 63 or the metal sheet three 64 are respectively adsorbed to drive the position of the rotating rod two 46 to move. According to the power-on status of the metal sheet one 62, the metal sheet two 63 and the metal sheet three 64, the three groups of moving positions of the rotating rod two 46 are controlled to realize gear switching, so as to adjust the rotation accuracy of the adjustment knob 42 according to the sample thickness.

[0031] When the motor 24 starts to work, the electromagnet ring 92 is energized, and the electromagnet ring 92 generates magnetism, which is adsorbed with the metal sheet 4 91, and the external temperature is monitored by the temperature monitor 81, triggering the trigger pointer 82 to rotate, and the trigger pointer 82 is pressed against the trigger switch seat 83, and the working time of the motor 2 79 is controlled according to the trigger signal of the trigger switch seat 83. The motor 2 79 drives the rotating rod 4 78 to rotate synchronously, and the rotating rod 4 78 drives the gear 8 77 to rotate, and the gear 8 77 drives the gear 75 to rotate, and the gear 75 drives the threaded seat 74 to rotate. With the cooperation of the thread, the screw 2 76 moves vertically, and the screw 2 76 drives the pressure needle member 14 to move vertically. The higher the temperature, the shorter the downward movement distance of the screw 2 76, and the lower the temperature, the longer the downward movement distance of the screw 2 76, so as to realize the compensation operation of the moving distance of the pressure needle member 14, adapt to low and high temperature environments, and reduce the risk of the ambient temperature affecting the hardness detection effect.
