Technical Field
[0001] The utility model belongs to the field of irregular solid volume density measuring equipment, in particular to an irregular solid volume measuring device. Background Art
[0002] In the laboratory, for various solid samples, such as minerals, metals, glass, ceramics, etc., it is often necessary to measure the volume of the samples and then calculate their volume density in order to study their causes and formation conditions or evaluate their performance. The volume of regular-shaped solids can be directly measured and calculated using the corresponding volume formula, but irregular solids do not have regular geometric shapes and their volumes cannot be determined by traditional methods.
[0003] When measuring the volume of irregular solids, the common methods include the displacement method, which calculates the volume based on the volume change of the object in water, and the method of hanging the object on a dynamometer, measuring the mass m1 of the object in the air, and then suspending the object in water and measuring the mass m2 of the object suspended in water. According to the buoyancy calculation formula, the volume of the object = (m1-m2) / ρ 水 The displacement method is a weighing method, but the accuracy of the displacement method is related to the accuracy of the container and the operating skills of the measurement personnel, so the accuracy of the measurement results cannot be guaranteed. Although the weighing method has accurate readings, its operation is cumbersome. It is difficult to hoist the object onto the dynamometer, and the hoisting device also has buoyancy in the water, which can easily affect the measurement accuracy.
[0004] To this end, the utility model provides a device for measuring the volume of irregular solids. Utility Model Content

[0008] Preferably, a guide block is fixedly connected to the side wall of the sliding arm; the guide block is arranged parallel to the sliding arm; the lifting block is slidably connected to the guide block; this can make the lifting block less likely to tilt when sliding, making the sliding of the lifting block more stable.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Specific examples are given below.
[0024] like Figure 1 and Figure 3As shown, an irregular solid volume measuring device described in an embodiment of the utility model comprises a support seat 1; two sliding arms 2 symmetrically arranged are fixedly connected to the top of the support seat 1; a lifting block 3 is slidably connected to the sliding arms 2; the lifting block 3 is internally rotatably connected to a rotating shaft 4; an adjusting gear 5 is fixedly connected to the rotating shaft 4; the adjusting gear 5 is meshedly connected to the sliding arm 2; a connecting rope 6 is fixedly connected to the bottom of the lifting block 3; a hook 7 is fixedly connected to the bottom end of the connecting rope 6; a hollow hanging basket 8 is hung on the hook 7; an electronic balance 9 is placed on the top of the support seat 1, and the electronic balance 9 is placed at a position corresponding to the bottom of the hollow hanging basket 8; during work, when it is necessary to measure the volume of an irregular solid, an electronic balance 9 with an accuracy of 0.01g can be placed on the top of the support seat 1, and a beaker filled with an appropriate amount of distilled water can be placed on the weighing pan of the electronic balance 9, and then the adjusting gear 5 can be driven by the rotating shaft 4 The gear 5 rotates, so that the adjusting gear 5 cooperates with the sliding arm 2, driving the lifting block 3 to slide on the sliding arm 2, first immersing the hollow hanging basket 8 in water, and stops descending when the marking line above the hollow hanging basket 8 touches the liquid surface, then turns on the power switch of the electronic balance 9 and adjusts it to zero, and then controls the lifting block 3 to rise, and after the hollow hanging basket 8 is lifted out of the liquid surface, the object to be measured is placed inside the hollow hanging basket 8, and then controls the lifting block 3 to descend again, so that the object to be measured is completely immersed in the water, and stops descending when the marking line touches the liquid surface again, and records the reading m after the electronic balance 9 stabilizes. The value of the reading m is the volume V of the object to be measured. During the entire measurement process, the hollow hanging basket 8 and the object to be measured cannot touch the wall and bottom of the beaker, and the distilled water in the beaker cannot overflow from the beaker. Since the hollow hanging basket 8 and the object to be measured do not touch the wall and bottom of the beaker during the measurement process, the measured mass m is equal to the mass of the water whose liquid surface has risen. According to the density formula, the volume v of this part of water 水 =ρ 水 ×m, density of distilled water ρ 水 1.0g / cm at room temperature 3 , so we have v 水 =m. According to Archimedes' principle, the volume of the water whose liquid level rises is equal to the volume of the object to be measured, so V = v 水 =m, which can make the measurement data of irregular solid volume more accurate.
[0025] like Figures 1 to 4As shown, a plurality of supporting feet 10 are fixedly connected to the bottom of the electronic balance 9, and the supporting feet 10 are arranged at positions corresponding to the corners of the bottom surface of the electronic balance 9; a sliding guide groove 11 is provided on the top of the support base 1; the supporting feet 10 slide and fit in the internal position of the sliding guide groove 11; a first fixed magnetic block 12 is fixedly connected to the bottom of the supporting foot 10; a second fixed magnetic block 13 is fixedly connected to the inside of the sliding guide groove 11; the first fixed magnetic block 12 and the second fixed magnetic block 13 are arranged to attract each other; during operation, when the electronic balance 9 needs to be placed, by setting the sliding guide groove 11 on the top of the support base 1 and placing the supporting feet 10 into the inside of the sliding guide groove 11, the placement of the electronic balance 9 is guided and restricted, so that the placement position of the electronic balance 9 can be made more accurate, and at the same time, by the attraction between the first fixed magnetic block 12 and the second fixed magnetic block 13, the electronic balance 9 can be placed more stably on the top of the support base 1.
[0026] like Figure 4 As shown, a guide block 14 is fixedly connected to the side wall of the sliding arm 2; the guide block 14 is arranged parallel to the sliding arm 2; the lifting block 3 is slidably connected to the guide block 14; during operation, when the lifting block 3 slides on the sliding arm 2, the sliding of the lifting block 3 is restricted by the guide block 14, so that the lifting block 3 is less likely to tilt when sliding, and the sliding of the lifting block 3 is more stable.
[0027] like Figures 4 to 5 As shown, a plurality of knocking plates 15 are fixedly connected to the side wall of the rotating shaft 4, and the knocking plates 15 are regularly arranged in a circular array on the rotating shaft 4; the knocking plates 15 are arranged at positions corresponding to the side walls of the lifting block 3; during operation, during the rotation of the rotating shaft 4, a flexible knocking plate 15 is arranged on the side wall of the rotating shaft 4 so as to rotate together with the rotating shaft 4, and the knocking of the side wall of the lifting block 3 by the knocking plate 15 can transmit vibration to the internal position of the hollow hanging basket 8 through the connecting rope 6 and the hook 7, so that when the hollow hanging basket 8 is placed inside the beaker, the bubbles adhering to the irregular solid surface can be cleaned by vibration, thereby effectively avoiding the situation where the bubbles affect the volume measurement of the irregular solid.
[0028] like Figure 5 As shown, a positioning block 16 is fixedly connected to the side wall of the rotating shaft 4; the positioning block 16 is rotatably connected to the internal position of the lifting block 3; during operation, when the rotating shaft 4 rotates inside the lifting block 3, the lifting block 3 limits the rotation of the positioning block 16, so that the rotating shaft 4 is less likely to tilt during rotation, thereby making the rotation of the rotating shaft 4 more stable.
[0029] like Figure 5As shown, a plurality of anti-wear balls 17 are provided between the lifting block 3 and the positioning block 16; the side walls of the anti-wear balls 17 are in contact with the side walls of the lifting block 3 and the positioning block 16; during operation, when the positioning block 16 rotates inside the lifting block 3, the sliding friction between the lifting block 3 and the positioning block 16 is converted into rolling friction, so that the friction force between the lifting block 3 and the positioning block 16 can be reduced, thereby reducing the wear between the lifting block 3 and the positioning block 16.
[0030] During operation, when it is necessary to measure the volume of irregular solids, an electronic balance 9 with an accuracy of 0.01g can be placed on the top of the support seat 1, and a beaker containing an appropriate amount of distilled water can be placed on the weighing plate of the electronic balance 9. Then, the adjusting gear 5 can be driven to rotate by the rotating shaft 4, so that the adjusting gear 5 cooperates with the sliding arm 2 to drive the lifting block 3 to slide on the sliding arm 2. First, the hollow hanging basket 8 is immersed in water, and when the marking line above the hollow hanging basket 8 contacts the liquid surface, it stops descending. Then, the power switch of the electronic balance 9 is turned on and zeroed, and then the lifting block 3 is controlled to rise, and the hollow hanging basket 8 is lifted out of the liquid. After the surface is formed, the object to be measured is placed in the hollow hanging basket 8, and then the lifting block 3 is controlled to descend again so that the object to be measured is completely immersed in the water. When the marking line touches the liquid surface again, the descending is stopped. After the electronic balance 9 is stable, the reading m is recorded. The value of the reading m is the volume V of the object to be measured. During the entire measurement process, the hollow hanging basket 8 and the object to be measured cannot contact the wall and bottom of the beaker, and the distilled water in the beaker cannot overflow from the beaker. Since the hollow hanging basket 8 and the object to be measured do not contact the wall and bottom of the beaker during the measurement process, the measured mass m is equal to the mass of the water whose liquid surface rises. According to the density formula, the volume v of this part of water 水 =ρ 水 ×m, density of distilled water ρ 水 1.0g / cm at room temperature 3 , so we have v 水 =m. According to Archimedes' principle, the volume of the water whose liquid level rises is equal to the volume of the object to be measured, so V = v 水 =m, which can make the measurement data of irregular solid volume more accurate.
[0031] When the electronic balance 9 needs to be placed, a sliding guide groove 11 is provided on the top of the support base 1, and the support foot 10 is placed inside the sliding guide groove 11 to guide and restrict the placement of the electronic balance 9, so that the placement position of the electronic balance 9 can be more accurate. At the same time, the first fixed magnetic block 12 and the second fixed magnetic block 13 are attracted to each other, so that the electronic balance 9 can be placed more stably on the top of the support base 1.
[0032] When the lifting block 3 slides on the sliding arm 2, the sliding of the lifting block 3 is limited by the guide block 14, so that the lifting block 3 is less likely to tilt during sliding, and the sliding of the lifting block 3 is more stable.
[0033] During the rotation of the rotating shaft 4, a flexible knocking plate 15 is arranged on the side wall of the rotating shaft 4 to rotate together with the rotating shaft 4. The knocking plate 15 knocks the side wall of the lifting block 3, so that the vibration can be transmitted to the internal position of the hollow hanging basket 8 through the connecting rope 6 and the hook 7. When the hollow hanging basket 8 is placed in the beaker, the bubbles adhered to the surface of the irregular solid can be cleaned by vibration, thereby effectively avoiding the situation where the bubbles affect the volume measurement of the irregular solid.
[0034] When the rotating shaft 4 rotates inside the lifting block 3, the lifting block 3 limits the rotation of the positioning block 16, so that the rotating shaft 4 is less likely to tilt during rotation, thereby making the rotation of the rotating shaft 4 more stable.
[0035] When the positioning block 16 rotates inside the lifting block 3, the sliding friction between the lifting block 3 and the positioning block 16 is converted into rolling friction, so that the friction between the lifting block 3 and the positioning block 16 can be smaller, thereby reducing the wear between the lifting block 3 and the positioning block 16.
[0036] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
