Description

Technical Field

[0001] This invention pertains to machining equipment, and more particularly relates to an environmentally friendly coolant circulation device for machining equipment. Background Technology

[0002] Coolant is a type of coolant that has more advantages than traditional coolant water, including sensitive thermal balance capability, superior heat conduction capability, ensuring the engine is at its optimal operating temperature; an ultra-wide operating temperature range, preventing boiling over and maintaining low pressure in the cooling system; no need to add antifreeze in low-temperature environments, avoiding corrosion damage such as cavitation, scale, and electrolysis, and good compatibility with rubber hoses.

[0003] In existing machining processes, cutting tools or drills are frequently used to cut, bore, grind, and engrave workpieces. These processes often require the use of coolant to cool the contact points between the tool and the workpiece, both to reduce temperature and to protect the tool. However, during actual production, machining debris mixes into the coolant. Discarding the debris would increase production costs and pollute the environment, while continued use could clog oil pipes and damage the cooling system. Therefore, filtering the coolant is essential to save production costs. To this end, we propose an environmentally friendly coolant circulation device for machining equipment. Summary of the Invention

[0004] This invention provides an environmentally friendly coolant circulation device for machining equipment, aiming to solve the problem of coolant clogging and blocking of oil pipes.

[0005] The present invention is implemented as follows: an environmentally friendly coolant circulation device for machining equipment, comprising: an oil storage tank, wherein the oil storage tank is connected and in communication with a filter box disposed on its upper part, and the filter box is connected to a receiving box through a connecting pipe; the oil storage tank, the filter box, and the receiving box are all rectangular structures, and the interior of all three are hollow structures.

[0006] A filter barrel is disposed inside the filter box and has multiple through holes at its bottom to filter the cooling oil in the receiving box.

[0007] A sealing plate, which has a cuboid structure, is disposed inside the connecting pipe to seal the connecting pipe;

[0008] A flipping mechanism is provided in the filter box and connected to the filter barrel. The flipping mechanism is used to flip the filter barrel in the filter box so that the workpiece debris in the filter barrel is poured out to the outside by the inclined plate on the side of the filter box.

[0009] The self-locking component is disposed between the receiving box and the connecting pipe and is connected to the sealing plate. During the process of the filter bucket flipping, the self-locking component is driven to move, so that the sealing plate seals the connecting pipe, and the connecting pipe is opened after the cooling oil in the receiving box reaches a certain liquid level.

[0010] Furthermore, the flipping mechanism is connected to the self-locking component via a power component, which includes a drive device fixedly mounted on the filter box, a lead screw connected to the output shaft of the drive device and rotatably mounted between the filter box and the connecting pipe, and a threaded sleeve that cooperates with the lead screw.

[0011] The threaded sleeve connects the flipping mechanism and the self-locking assembly.

[0012] Furthermore, the flipping mechanism includes guide components symmetrically arranged within the filter box, and a meshing structure connected to the guide components and disposed between the filter box and the filter barrel;

[0013] The guide assembly is connected to the threaded sleeve via a connector.

[0014] Furthermore, the guide assembly includes a guide rod fixedly installed between the inner walls of the filter box and a sliding block slidably disposed on the guide rod;

[0015] The sliding block is connected to the connector, and the rotating shaft of the filter bucket is rotatably connected to the sliding block.

[0016] Furthermore, the meshing structure includes a rack plate fixedly installed between the inner walls of the filter box and arranged parallel to the guide rod, and a gear fixedly installed on the rotating shaft of the filter barrel and cooperating with the rack plate.

[0017] Furthermore, the self-locking assembly includes an elastic structure connected to the sealing plate and disposed between the connecting pipe and the receiving box, and an unlocking structure cooperating with the elastic structure and disposed on the receiving box;

[0018] The sealing plate has mounting plates symmetrically installed on both sides, and the end of the mounting plate away from the sealing plate is connected by a crossbar, which is adapted to the threaded sleeve plate.

[0019] Furthermore, the elastic structure includes a baffle fixedly installed on the receiving box, a support rod fixedly connected to the sealing plate and slidably disposed on the baffle, and a spring sleeved on the support rod;

[0020] One end of the spring is connected to the sealing plate, and the other end is connected to the baffle.

[0021] Furthermore, the unlocking structure includes a connecting rod rotatably installed inside the receiving box, a float fixedly installed at the end of the connecting rod away from its hinged end with the receiving box, and a limiting block slidably disposed at the lower part of the receiving box;

[0022] The limiting block is connected to the connecting rod via a traction rope, and the limiting block is adapted to the triangular protrusion located at the end of the sealing plate near the spring.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] Since most existing cooling circulation devices lack filtration capabilities and are prone to generating debris during workpiece processing, which can easily clog oil pipes when mixed with coolant, we have implemented a filter tank to filter the coolant. Simultaneously, the filter residue in the tank is periodically emptied to ensure that the circulating coolant is free of mechanical debris. Furthermore, by incorporating a receiving tank, a filter tank, and an oil storage tank, we separate the hot coolant from the cooled coolant, preventing their mixing and subsequent temperature rise, which would reduce the cooling effect.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] To effectively illustrate the embodiments of the present invention, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0036] Please see Figure 1-5 This invention provides an environmentally friendly coolant circulation device for machining equipment to solve the problem of coolant clogging of oil pipes.

[0037] An embodiment of the present invention provides an environmentally friendly coolant circulation device for machining equipment, comprising: an oil storage tank 1, a filter barrel 19, a sealing plate 9, a tilting mechanism, a self-locking component, and a power component;

[0038] The oil storage tank 1 is connected and communicates with the filter box 2 located on its upper part, and the filter box 2 is connected to the receiving box 3 through the connecting pipe 8. The oil storage tank 1, the filter box 2 and the receiving box 3 are all rectangular structures, and the interior of all three are hollow structures.

[0039] During use, the oil reservoir 1 and the receiving tank 3 are connected by a filter box 2. On the one hand, the filter box 2 can filter the coolant. On the other hand, the intermittent connection between the oil reservoir 1 and the receiving tank 3 allows the coolant in the receiving tank 3 to be cooled before being poured back into the oil reservoir 1, thus preventing the coolant from not being effectively cooled during the circulation process and reducing its cooling effect.

[0040] The filter bucket 19 is disposed inside the filter box 2 and has multiple through holes at its bottom to filter the coolant in the receiving box 3.

[0041] The sealing plate 9 is a cuboid structure and is installed inside the connecting pipe 8 to seal the connecting pipe 8;

[0042] The flipping mechanism is disposed in the filter box 2 and connected to the filter barrel 19. The flipping mechanism is used to flip the filter barrel 19 in the filter box 2 so that the workpiece debris in the filter barrel 19 can be poured out by the inclined plate 25 on the side of the filter box 2.

[0043] The flipping mechanism includes guide components symmetrically arranged in the filter box 2, and a meshing structure connected to the guide components and disposed between the filter box 2 and the filter barrel 19;

[0044] The guide assembly is connected to the threaded sleeve 15 via connector 18;

[0045] The guide assembly includes a guide rod 21 fixedly installed between the inner walls of the filter box 2 and a sliding block 20 slidably disposed on the guide rod 21;

[0046] The sliding block 20 is connected to the connector 18, and the rotating shaft of the filter barrel 19 is rotatably connected to the sliding block 20;

[0047] The meshing structure includes a rack plate 23 fixedly installed between the inner walls of the filter box 2 and arranged parallel to the guide rod 21, and a gear 22 fixedly installed on the rotating shaft of the filter barrel 19 and cooperating with the rack plate 23.

[0048] In use, the power unit drives the sliding block 20 to move on the guide rod 21, and drives the gear 22 to move on the rack plate 23. The gear 22 meshes with the rack plate 23, thereby causing the filter barrel 19 to flip and pour out the filtered impurities inside.

[0049] The center of rotation of the filter barrel 19 is located at its upper part, and in the initial state, the center of gravity of the filter barrel 19 is located at the lower part of its rotation axis, so that its opening can always face upwards.

[0050] It should be noted that only a portion of the rack plate 23 has teeth. During the initial movement of the filter barrel 19, the gear 22 will not rotate. It will only rotate under the action of the gear 22 and the rack plate 23 when the filter barrel 19 moves to a new position. The above arrangement is mainly to ensure that the filter barrel 19 will not interfere with the inner wall of the filter box 2 during its rotation.

[0051] The self-locking component is disposed between the receiving box 3 and the connecting pipe 8. The self-locking component is connected to the sealing plate 9. During the process of the filter bucket 19 being flipped, the self-locking component is driven to move, so that the sealing plate 9 seals the connecting pipe 8. After the coolant in the receiving box 3 reaches a certain liquid level, the connecting pipe 8 is opened.

[0052] The self-locking component includes an elastic structure connected to the sealing plate 9 and disposed between the connecting pipe 8 and the receiving box 3, and an unlocking structure cooperating with the elastic structure and disposed on the receiving box 3;

[0053] The sealing plate 9 is symmetrically equipped with mounting plates 13 on both sides, and the end of the mounting plate 13 away from the sealing plate 9 is connected by a crossbar 14, which is adapted to the threaded sleeve plate 15.

[0054] The elastic structure includes a baffle 10 fixedly installed on the receiving box 3, a support rod 11 fixedly connected to the sealing plate 9 and slidably disposed on the baffle 10, and a spring 12 sleeved on the support rod 11;

[0055] One end of the spring 12 is connected to the sealing plate 9, and the other end is connected to the baffle 10;

[0056] The unlocking structure includes a connecting rod 4 rotatably installed inside the receiving box 3, a float 5 fixedly installed at the end of the connecting rod 4 away from the hinged end with the receiving box 3, and a limiting block 7 slidably disposed at the lower part of the receiving box 3;

[0057] The limiting block 7 is connected to the connecting rod 4 via the traction rope 6, and the limiting block 7 is adapted to the triangular protrusion 24 located at one end of the sealing plate 9 near the spring 12.

[0058] When the power unit drives the crossbar 14 to move, the spring 12 is compressed and stores elastic potential energy. This energy is then released when the triangular protrusion 24 on the sealing plate 9 engages with the limiting block 7, thus fixing the sealing plate 9 and sealing the connecting pipe 8. During this process, the filter bucket 19 flips once, and then the power unit reverses to drive the filter bucket 19 back to its initial position. At this time, under the action of the triangular protrusion 24, the sealing plate 9 remains in a fixed position until the coolant level in the receiving box 3 reaches a certain height. Under the action of the float 5, the connecting rod 4 rotates and pulls the limiting block 7 upward through the traction rope 6 until the limiting block 7 separates from the triangular protrusion 24. The spring 12 releases its elastic potential energy, causing the sealing plate 9 to move, and the coolant in the receiving box 3 can flow into the filter bucket 19 for filtration.

[0059] The flipping mechanism is connected to the self-locking component via a power component. The power component includes a drive device 17 fixedly installed on the filter box 2, a lead screw 16 connected to the output shaft of the drive device 17 and rotatably installed between the filter box 2 and the connecting pipe 8, and a threaded sleeve 15 that cooperates with the lead screw 16.

[0060] The threaded sleeve 15 connects the flipping mechanism and the self-locking assembly.

[0061] In use, by controlling the drive device 17 to rotate, the lead screw 16 is driven to rotate, so that the threaded part 15 that is threaded with the lead screw 16 moves in the axial direction of the lead screw 16, and drives the crossbar 14 and the sliding block 20 to move.

[0062] Taking the embodiment combining all the features described in this application as an example, in use, the device is placed at the lower part of the machine tool, and the funnel on the receiving box 3 is aligned with the oil collection port on the machine tool. In the initial state, the sealing plate 9 seals the connecting pipe 8. As the receiving box 3 continuously collects coolant, the coolant level rises continuously until, under the action of the float 5, the connecting rod 4 rotates to a certain angle, and the traction rope 6 pulls the limiting block 7 upward, causing the limiting block 7 to separate from the triangular protrusion 24 provided on the sealing plate 9. At this time, the spring 12... Releasing elastic potential energy, the coolant in the receiving box 3 moves into the oil reservoir 1 under the action of gravity and is filtered by the filter barrel 19. After the coolant in the receiving box 3 is drained, the drive device 17 drives the lead screw 16 to rotate, and drives the sliding block and the sealing plate 9 to move through the threaded sleeve plate 15. Under the action of the gear 22 and the rack plate 23, the filter barrel 19 is flipped over, and the sealing plate 9 moves in the opposite direction, so that the triangular protrusion 24 engages with the limiting block 7 to block the connecting pipe 8. The above steps are repeated to filter the coolant.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
