Description

Technical Field

[0001] This utility model belongs to the field of laboratory instrument technology, and more specifically it relates to a quantitative liquid addition device for experiments with water-based fully synthetic cutting fluid. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate machine tools and workpieces. It is made of a variety of high-performance additives through scientific compounding. Cutting fluid has good cooling, lubrication, rust prevention, degreasing and cleaning, and anti-corrosion properties. It has excellent cooling, cleaning and rust prevention characteristics, and is non-toxic, odorless, non-corrosive to humans, non-corrosive to equipment, and non-polluting to the environment.

[0003] In cutting fluid performance testing experiments, the amount of cutting fluid added needs to be precisely controlled in order to evaluate its lubricity, cooling performance and other indicators.

[0004] Existing technologies mostly employ electronic pumps or gravity dripping methods, which have the following drawbacks:

[0005] Electronic pumps rely on sensors and controllers, are costly and susceptible to electromagnetic interference, and have low accuracy in gravity-based dripping, making it difficult to achieve micro-quantitative dispensing. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quantitative liquid addition device for water-based fully synthetic cutting fluid experiments, which has the advantage of convenient quantitative liquid addition.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A metering device for experimental use of water-based fully synthetic cutting fluid includes: a reservoir tube for storing the water-based fully synthetic cutting fluid; an outlet tube fixedly installed at the bottom of the reservoir tube and communicating with the inside of the reservoir tube; a piston assembly disposed inside the reservoir tube and capable of reciprocating within the reservoir tube; an adjusting mechanism connected to the piston assembly for controlling piston formation to achieve metered dispensing; a one-way valve for discharging liquid disposed inside the outlet tube for controlling the flow direction of the liquid; and a sealing cap threadedly connected to the opening of the reservoir tube for sealing the entire reservoir tube.

[0009] The advantages of this scheme are at least as follows: when a quantitative liquid addition device is required, liquid is added into the storage tube by unscrewing the sealing cap, and the sealing cap is then closed. By rotating the adjustment mechanism clockwise, the adjustment mechanism drives the piston assembly connected to it to move downward in the storage tube. During the downward movement, the piston assembly pushes the liquid, and the one-way valve opens. The movement of the piston assembly in the storage tube can be precisely controlled by the adjustment mechanism, thereby achieving quantitative liquid addition.

[0010] The present invention is further configured such that: a mounting bracket is fixedly installed on the top of the sealing cover; the adjusting mechanism includes a worm gear and a worm shaft rotatably mounted on the mounting bracket, the worm gear and the worm shaft meshing with each other; the piston assembly consists of a threaded rod and a piston rod; a threaded hole is provided at the center of the sealing cover and the worm gear; and the threaded rod is threadedly connected to the threaded hole.

[0011] The present invention is further configured such that: a knob is fixedly installed at one end of the worm gear, and a gripping block is provided on the outer wall of the knob.

[0012] The advantages of this scheme are at least as follows: the knob allows users to rotate the worm gear more easily, and the pinch block allows users to apply force more easily by utilizing the friction between themselves and the knob, thus making it easier and more precise to adjust the mechanism, thereby controlling the stroke of the piston assembly in the liquid storage tube, and ultimately achieving precise quantitative liquid addition.

[0013] The present invention is further configured such that: the liquid storage tube is made of transparent material, and scale markings are provided on the outer surface of the liquid storage tube.

[0014] The advantages of this solution are at least as follows: the transparent reservoir tube allows for a clear view of the remaining cutting fluid level, facilitating observation and timely replenishment; the graduated markings provide a clear fluid level reference, allowing users to adjust the amount of fluid added to avoid overfilling or underfilling, thus improving operational accuracy and efficiency.

[0015] The present invention is further configured such that: a fixed bracket is installed on the outer surface of the liquid storage tube, the fixed bracket adopts a telescopic structure, and a silicone sheet is provided at the bottom of the fixed bracket.

[0016] The advantages of this solution are at least as follows: the retractable fixed bracket allows the height and position of the liquid storage tube to be adjusted according to experimental or production needs, adapting to different operating environments and spatial layouts, improving the adaptability and practicality of the device; the silicone sheet can increase the friction between the fixed bracket and the tabletop, preventing slippage during use.

[0017] The present invention is further configured such that reinforcing rods are symmetrically installed on the fixed bracket.

[0018] The advantages of this scheme are at least as follows: The symmetrically installed reinforcing rods can effectively distribute the pressure on the fixed bracket, improve its overall structural strength and rigidity, and prevent the bracket from bending or deforming during use.

[0019] The present invention is further configured such that a limiting block is fixedly installed at the end of the threaded rod away from the piston rod.

[0020] The advantages of this scheme are at least as follows: the function of the limit block is to limit the rotational stroke of the threaded rod, prevent the threaded rod from being excessively screwed out or into, and ensure that the movement of the piston assembly is within a predetermined range.

[0021] The present invention is further configured such that: a stabilizing block is provided on the top of the sealing cover, and the threaded rod is rotatably mounted on the stabilizing block.

[0022] The advantages of this scheme are at least as follows: the stabilizing block can reduce the shaking or tilting of the threaded rod during rotation, ensuring smoother rotation.

[0023] In summary, this utility model has at least the following advantages:

[0024] 1. By setting up a piston assembly and an adjustment mechanism, when a quantitative liquid addition device is needed, liquid is added into the storage tube by unscrewing the sealing cap, and the sealing cap is closed. By rotating the adjustment mechanism clockwise, the adjustment mechanism drives the piston assembly connected to it to move downward in the storage tube. During the downward movement, the piston assembly pushes the liquid, and the one-way valve opens. The movement of the piston assembly in the storage tube can be precisely controlled by the adjustment mechanism, thereby realizing quantitative liquid addition.

[0025] 2. By setting a knob and a pinch block, the knob makes it easier for the user to rotate the worm gear, and the pinch block allows the user to apply force more easily by using the friction between the user and the knob, thus making it easier and more precise to adjust the mechanism, thereby controlling the stroke of the piston assembly in the liquid storage tube, and finally achieving precise quantitative liquid addition.

[0026] 3. By setting a limit block, the function of the limit block is to limit the rotation stroke of the threaded rod, prevent the threaded rod from being excessively screwed out or screwed in, and ensure that the movement of the piston assembly is within the predetermined range.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] A metering device for experimental application of a water-based fully synthetic cutting fluid, such as... Figure 1 , Figure 2 As shown, it includes: a reservoir tube 1 for storing water-based fully synthetic cutting fluid, the reservoir tube 1 being made of transparent material, with graduation markings 11 on its outer surface; an outlet tube 2, fixedly installed at the bottom of the reservoir tube 1 and communicating with the interior of the reservoir tube 1; a piston assembly 3, located inside the reservoir tube 1, capable of reciprocating within the reservoir tube 1; an adjusting mechanism 4, connected to the piston assembly 3, used to control piston formation for metered fluid dispensing; a drain check valve 5, located inside the outlet tube 2, used to control the flow direction of the liquid; and a sealing cap 6, threadedly connected to the opening of the reservoir tube 1, used to seal the entire reservoir tube 1. Figure 4 As shown, a stabilizing block 16 is provided on the top of the sealing cover 6, and the threaded rod 301 is rotatably mounted on the stabilizing block 16.

[0034] like Figure 2 As shown, a mounting bracket 7 is fixedly installed on the top of the sealing cover 6. The adjusting mechanism 4 includes a worm gear 401 and a worm 402 rotatably mounted on the mounting bracket 7. The worm gear 401 and the worm 402 mesh with each other. The piston assembly 3 consists of two parts: a threaded rod 301 and a piston rod 302. A threaded hole 8 is provided at the center of the sealing cover 6 and the worm gear 401. The threaded rod 301 is threadedly connected in the threaded hole 8.

[0035] It is worth mentioning that a knob 9 is fixedly installed at one end of the worm gear 402. A gripping block 10 is provided on the outer wall of the knob 9. The knob 9 makes it easier for the user to rotate the worm gear 402. The gripping block 10 allows the user to apply force more easily by using the friction between the user and the knob 9, thereby adjusting the mechanism 4 more easily and accurately, and controlling the stroke of the piston assembly 3 in the liquid storage tube 1, ultimately achieving precise quantitative liquid addition.

[0036] In some embodiments, in order to prevent the threaded rod 301 from being excessively screwed out or screwed in, a limiting block 15 is fixedly installed at the end of the threaded rod 301 away from the piston rod 302. The limiting block 15 restricts the rotational stroke of the threaded rod 301 and ensures that the movement of the piston assembly 3 is within a predetermined range.

[0037] like Figure 1 As shown, in order to facilitate the storage and fixation of the liquid storage tube 1, in some embodiments, a fixing bracket 12 is installed on the outer surface of the liquid storage tube 1. The fixing bracket 12 adopts a telescopic structure, and a silicone sheet 13 is provided at the bottom of the fixing bracket 12. The telescopic fixing bracket 12 allows the height and position of the liquid storage tube 1 to be adjusted according to experimental or production needs, adapting to different operating environments and spatial layouts, improving the adaptability and practicality of the device. The silicone sheet 13 can increase the friction between the fixing bracket 12 and the tabletop, preventing slippage during use.

[0038] It is worth mentioning that reinforcing rods 14 are symmetrically installed on the fixed bracket 12. The symmetrically installed reinforcing rods 14 can effectively distribute the pressure borne by the fixed bracket 12, improve its overall structural strength and rigidity, and prevent the bracket from bending or deforming during use.

[0039] The working process and beneficial effects of this utility model are as follows:

[0040] When the metering device is needed, liquid is added into the storage tube 1 by unscrewing the sealing cap 6, and then the sealing cap 6 is closed. The knob 9 is turned clockwise, which drives the worm gear 402. The worm gear 402 drives the worm wheel 401 to rotate on the mounting bracket 7. As the worm wheel 401 rotates, it drives the threaded rod 301, which is threaded at its center, to rotate, causing the threaded rod 301 and the piston rod 302 to move downward in the storage tube 1. The adjusting mechanism 4 drives the piston assembly 3 connected to it to move downward in the storage tube 1. During the downward movement, the piston assembly 3 pushes the liquid, causing the one-way valve to open. The movement of the piston assembly 3 in the storage tube 1 can be precisely controlled by the adjusting mechanism 4, and the metering is achieved by the scale markings 11 on the storage tube 1.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
