Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary facilities for machining workshops, and in particular to a cutting fluid filling vehicle. Background Art

[0002] Cutting fluid is an industrial liquid used in the process of metal cutting and grinding to cool and lubricate tools and workpieces. Cutting fluid is scientifically compounded with a variety of super-functional additives. It has good cooling performance, lubrication performance, rust prevention performance, oil removal and cleaning functions, anti-corrosion function and easy dilution. Cutting fluid is an important factor in ensuring the normal operation of machine tools, machining centers and other equipment. During the process of parts processing, metal debris will be mixed into the cutting fluid. In order to recycle the cutting fluid, it is usually necessary to use a filtration system to filter out the aforementioned metal debris. During the recycling process, the cutting fluid stored in the equipment is gradually lost, so it is necessary to regularly add cutting fluid to ensure the normal operation of the equipment.

[0003] For machining workshops that centrally supply cutting fluid, it is a basic requirement in the industry to quickly transfer the cutting fluid to the application equipment and quickly and stably add the cutting fluid. The specification of Chinese utility model patent CN219131679U discloses such a mobile cutting fluid filling device, including a cutting fluid storage box and a filling gun assembly arranged on the cutting fluid storage box, a control box protruding upward is provided at the rear end of the top surface of the cutting fluid storage box, a filling pump is provided in the control box, a liquid level gauge is provided on the front side of the cutting fluid storage box, the liquid level gauge is connected to the cutting fluid storage box, and the front side of the cutting fluid storage box is in the shape of a slope that tilts upward and inward; the filling gun assembly is arranged at the front of the top surface of the cutting fluid storage box and is connected to the filling pump. The mobile cutting fluid filling device has the following defects: first, the overall structural strength, especially the structural strength of the cutting fluid storage box, is insufficient, and it is easy to leak due to collision and other factors when it is moved in the machining workshop; second, there is a lack of protection at the necessary position, which makes the filling reel easy to get stuck; third, when the filling reel is tangled and entangled, the lack of appropriate means causes the pressure in the pipe to continue to rise, resulting in a pipe burst. In summary, the structure of the filling vehicle needs to be optimized to solve the above technical problems. Utility Model Content

[0022] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0023] See also Figure 1 , Figure 2 and Figure 4 The cutting fluid filling vehicle of the utility model includes a chassis 2 with wheels 3 installed, a liquid storage tank 19 with multiple internal box ribs 22 is installed on the chassis 2, a front box body 1 is installed at the front of the chassis 2, and a rear box body 13 is installed at the rear, and the height of the rear box body 13 is greater than the height of the front box body 1. The liquid storage tank 19 is located inside the front box body 1 and the rear box body 13.

[0024] As shown in the figure, the chassis 2 is a steel structure frame, and four wheels 3 are provided and respectively located at the four corners of the bottom of the chassis 2. The two front wheels 2 are fixed casters, and the two rear wheels 3 are brake-type universal casters. In this way, when the operator pushes the cutting fluid filling vehicle to move and turn in the machining workshop, when reaching the side of the equipment that needs to be filled with cutting fluid, it stops moving and steps on the brake-type universal casters to park.

[0025] The liquid storage tank 19 is a rectangular box, which stores cutting fluid collected by the centralized cutting fluid supply facility of the machining workshop (such as a ton barrel containing cutting fluid, etc.). By installing multiple internal box ribs 22 inside, the overall structural strength of the liquid storage tank 19 is improved, and the liquid storage tank 19 is installed in a built-in manner. Both the front box 1 and the rear box 13 provide a certain degree of external protection for it, and the liquid storage tank 19 will not be directly hit in the event of a collision. In this embodiment, the internal box ribs 22 are square metal plates with windows in the middle and bottom, and the edges around them are fixedly connected to the top wall, bottom wall and left and right side walls of the liquid storage tank 19 respectively. One of the functions of setting the windows on the internal box ribs 22 is to allow the cutting fluid to flow freely in the box, and the other function is to avoid water hammer in the liquid storage tank 19 during the movement of the filling vehicle.

[0026] In this embodiment, the front of the front box body 1 is open and is equipped with a front box door 5 with a door lock, and the left and right sides of the rear box body 13 are open and are equipped with rear box doors 4 with door locks. When necessary, the front box door 5 and the rear box door 4 are opened to operate the interior. A liquid replenishment pipeline (not shown in the figure) is installed on the liquid storage tank 19. The liquid replenishment pipeline can pass through the box wall of the front box body 1 or the rear box body 13 to extend to the outside, or it can be located inside the box and the liquid replenishment pipeline is exposed when the front box door 5 or the rear box door 4 is opened.

[0027] A first boss 6 and a second boss 10 are respectively provided on both sides of the top of the front box body 1, a bracket 7 is installed on the top wall of the front box body 1 and between the first boss 6 and the second boss 10, a filling reel 12 is installed on the bracket 7, a filling hose 11 is wound around the filling reel 12, a filling gun 9 is installed at the end of the filling hose 11, and a connecting hose 8 is provided on the side of the filling reel 12.

[0028] The first boss 6 and the second boss 10 provide a certain degree of protection for the filling reel 12 located inside, preventing foreign matter from entering the internal action space and causing the reel to become stuck, while also preventing the operator's limbs from entering the internal action space to a certain extent, thereby improving safety.

[0029] The bracket 7 supports the rotating shaft of the filling reel 12, so that the filling reel 12 can rotate flexibly, so that when the filling hose 11 is pulled, the filling reel 12 rotates forward and continues to unwind. When the cutting fluid filling operation is completed, the filling shaft 12 can be rotated in the reverse direction to rewind the filling hose 11. The connecting hose 8 is used to connect to an external pipeline. As shown in the figure, the connecting hose 8 is connected to the side of the filling shaft 12, specifically, it is connected to the end of the shaft of the filling reel 12 by a rotary seal. The shaft of the filling reel 12 is a hollow shaft, and the inner end of the filling hose 11 is connected to a joint set on the side wall of the shaft. In this way, when the filling shaft 12 rotates to unwind and rewind the filling hose 11, due to the effect of the rotary seal, the inner cavities of the connecting hose 8 and the filling hose 11 remain connected.

[0030] In this embodiment, the filling gun 9 is an automatic jump-gun type filling gun, and the filling gun automatically jumps to stop filling when the filling liquid level immerses the muzzle of the filling gun 9. That is to say, the filling gun 9 selected in this embodiment is the same as the refueling gun used in the gas station. When filling the cutting fluid, the muzzle of the filling gun 9 is placed in the cutting fluid storage tank of the on-site equipment. As the liquid level in the storage tank gradually rises, when the liquid level finally immerses the muzzle of the filling gun 9, the filling gun 9 automatically jumps, and the cutting fluid stops filling.

[0031] See also Figure 3 and Figure 4 , we can see that:

[0032] A charging pump 21 is installed in the rear housing 13, an input pipe 26 is installed at the inlet of the charging pump 21, and the lower end of the input pipe 26 extends to the bottom of the inner cavity of the liquid storage tank 19, an output pipe 25 with a flow meter 27 is installed at the outlet of the charging pump 21, and the connecting hose 8 is butt-connected to the output pipe 25. When the charging pump 21 is running, the cutting fluid is extracted from the inside of the liquid storage tank 19 through the input pipe 26, and supplied to the charging hose 11 through the output pipe 25 and the connecting hose 8.

[0033] An overflow pipe 29 with an overflow valve 28 is also connected to the output pipe 25, and the overflow pipe 29 extends to the inside of the liquid storage tank 19. The purpose of setting the overflow pipe 29 with the overflow valve 28 is that in some cases, such as when the filling hose 11 is kinked or the pipeline is blocked, the pressure inside the filling hose 11 will continue to increase. When the pressure exceeds the set value, the overflow valve 28 opens, and the cutting fluid in the output pipe 25 flows back to the liquid storage tank 19 through the overflow pipe 29, thereby effectively avoiding the problem of pipe burst caused by the uncontrollable increase of pressure in the pipeline, making the operation safer and more reliable.

[0034] In this embodiment, an explosion-proof filter bottle 20 is also installed on the input pipe 26. The explosion-proof filter bottle 20 filters the cutting fluid flowing through to remove particulate impurities and improve the purity of the cutting fluid, which is conducive to ensuring the stable operation of facilities such as machine tools. The bottom of the explosion-proof filter bottle 20 is provided with a drain valve, and the drain valve is opened regularly to discharge the impurities inside.

[0035] A battery 23 and a controller 24 are also installed inside the rear box 13. The battery 23 is used to store electrical energy, so that the cutting fluid filling vehicle can be independent of power supply cables and can be moved more flexibly and conveniently in the machining workshop. The controller 24 is built based on a PLC chip and is used to provide control functions for the filling vehicle.

[0036] In this embodiment, the upper rear side of the rear box 13 is an inclined surface, on which a touch screen 15 connected to the controller 24, a power switch 16 and a control button 18 are installed, and a charging interface 17 is also installed on the rear box 13. The battery 23 is replenished with electric energy through the charging interface 17, the filling vehicle is powered on and off through the power switch 16, some working condition information such as the filling flow of the cutting fluid is displayed through the touch screen 15, and control instructions are input through the control button 18, such as selecting a single filling amount of the cutting fluid.

[0037] In this embodiment, a handrail 14 is installed in the middle of the rear side of the rear box body 13. The purpose of providing the handrail 14 is to improve the operating convenience of the cutting fluid filling vehicle when it is pushed and moved.
