Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fixed beam gantry, in particular to a lightweight fixed beam gantry machining center. BACKGROUND

[0002] The fixed beam gantry machining center is developed from the numerical control machine tool, and is widely used for fine machining and semi-fine machining of mold parts. The fixed beam gantry boring and milling machine tool is mainly composed of a gantry with a y-axis and a z-axis and a workbench with an x-axis, and a clamp for clamping a workpiece to be machined is installed on the workbench. The gantry provides a tool head with a tool changing function.

[0003] According to the disclosure (announcement) number: CN115383188A, the disclosure (announcement) date: 2022-11-25, a kind of fixed beam gantry milling machine's assembly process is disclosed.

[0004] According to the disclosure (announcement) number: CN116748906A, the disclosure (announcement) date: 2023-09-15, a kind of machining center of vertical fixed beam gantry structure is disclosed.

[0005] According to the disclosure (announcement) number: CN116652660A, the disclosure (announcement) date: 2023-08-29, a kind of fixed beam gantry machining center is disclosed.

[0006] In the prior art including the above three groups of patents, different tools are replaced for boring, milling and drilling of different parts, but resonance will inevitably occur between the tool and the part during processing, causing vibration marks to appear on the part processing position, and as the tool continues to process, the tool will gradually increase the amplitude on the basis of the vibration marks, causing a large number of vibration marks to appear on the part processing, affecting the yield, and the amplitude is too large to be easily transmitted to the tool and cause damage to the x-axis to stop, and when the tool mills the part, the tool is processed on the upper surface of the part, at this time the vibration of the part can be combined through the clamp on the workbench, so that the clamp has a larger force transmission and absorption area to keep stable, and one of the vibration sources in the resonance condition is broken; but for boring and drilling processing methods, the tool head must pass through the workpiece, so the clamp needs to maintain a distance to provide the tool with a space to pass through the workpiece without being disturbed by the clamp, and in the case of a distance between the clamps, the force transmitted and absorbed by the clamp will be greatly reduced, at this time the vibration of the part cannot be absorbed by the clamps far away from each other, so one of the vibration sources in the resonance condition still exists, thereby affecting the yield of the part during processing, but in general, a common rubber pad is installed between the clamp and the workbench to absorb one of the vibration sources, but the rubber pad at this position is simultaneously subjected to external factors such as sliding of the clamp, weight of the workpiece, and flushing of mixed cutting fluid and waste, which can easily cause the rubber pad at this position to be severely worn, and the effect of the worn rubber pad on absorbing the vibration source will gradually decrease, causing the part yield to gradually become unqualified, thereby requiring regular maintenance and replacement to ensure the part yield, thereby reducing the part processing efficiency and increasing the production cost. SUMMARY

[0007] The purpose of the present application is to provide a lightweight fixed beam gantry machining center, which aims to solve the above problems.

[0008] In order to achieve the above purpose, the present application provides the following technical solutions:

[0009] A lightweight fixed beam gantry machining center, comprising a fixed beam frame provided with a workbench and a clamp, further comprising a suction member arranged between the workbench and the clamp, the suction member is divided into a lower rubber pad and an upper rubber pad with notches on the end faces, and the two notches are connected to form a symmetrically arranged static section;

[0010] The static section is provided with cutting fluid;

[0011] A liquid storage section is arranged between the lower rubber pad and the upper rubber pad, and the liquid storage section is used to guide the cutting fluid to the static section;

[0012] Further comprising a transfer section arranged between the liquid storage section and the static section, the transfer section is provided with a plurality of upper and lower staggered arranged intercepting members for filtering the cutting fluid.

[0013] Preferably, the intercepting member is divided into a lower intercepting strip and an upper intercepting strip, and the ends of the two strips are bent to face each other to block the cutting fluid.

[0014] Preferably, a plurality of intercepting holes are formed in the inner side of the lower intercepting strip, and a plurality of flow guiding holes are formed in the upper intercepting strip to face the intercepting holes, and the flow guiding holes are used to store the cutting fluid and the waste chips.

[0015] Preferably, a plurality of holes for conveying gas and liquid are arranged on the upper rubber pad to face the lower rubber pad, and an elastic member is arranged in the inner side of the upper rubber pad to abut the lower rubber pad.

[0016] The elastic member separates the gas and the liquid and is used to cooperate with the intercepting member to form a mixing section and a drainage section.

[0017] Preferably, a plurality of main nozzles and auxiliary nozzles are formed in the upper rubber pad to communicate with the drainage section, and the main nozzles and the auxiliary nozzles are arranged in a triangular shape with the top corner facing away from the workbench.

[0018] Preferably, the main nozzles and the auxiliary nozzles spray the cutting fluid to be atomized to cover the clamp.

[0019] Preferably, the cutting fluid in the state of covering the clamp cooperates with the part cage arranged on the clamp.

[0020] Preferably, an inclined flow channel is formed in the upper rubber pad to guide the cutting fluid in the state of covering the clamp.

[0021] Preferably, a slow flow hole is formed in the upper intercepting strip to communicate with the flow guiding hole and the inclined flow channel, respectively.

[0022] Preferably, the slow flow hole cooperates with the intercepting member to divert the cutting fluid in the transfer section.

[0023] In the above technical solution, the lightweight fixed-beam gantry machining center provided by the present invention has the following beneficial effects: Filtered cutting fluid is injected into the storage chamber and retention chamber via a rubber hose through the worktable. The cutting fluid in the storage section is decelerated by multiple interceptors in the transfer section, causing the cutting fluid entering the stationary section to remain stationary. The fixture clamps and fixes the part. At this time, the tool on the fixed beam performs boring and drilling operations on the part. During the machining process, the vibration source on the part is transmitted to the adsorption component via the fixture. The vibration source is then transferred and adsorbed through a double layer of lower and upper rubber pads before being transmitted to the worktable. This allows the worktable to provide more stable support for the adsorption component and fixture, maintaining a stable transmission and adsorption effect even when there are gaps between the fixtures, thus achieving better vibration source elimination. The cutting fluid in the stationary section is then transferred to the lower rubber pad... The vibration sources on the upper and lower rubber pads are absorbed by the liquid, allowing the cutting fluid to further absorb and transmit the vibration sources. This significantly reduces the vibration sources generated on the parts, preventing the parts from providing one of the vibration sources that could cause vibration marks in the machined inner holes, thus improving the part's yield. Furthermore, the cutting fluid in the stationary section provides better lubrication between the lower and upper rubber pads, making the adsorption component less susceptible to damage from wear between the worktable and fixture during prolonged operation. This results in a longer service life compared to traditional rubber buffer pads. With the continuous replacement of the cutting fluid in the stationary section, the adsorption component maintains a stable adsorption efficiency for the resources transmitted from the fixture, preventing a decrease in vibration absorption efficiency due to prolonged use. This effectively increases the stability of the fixed-beam gantry machining center during operation and improves the yield of the production line. Attached Figure Description

DETAILED DESCRIPTION

[0035] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0036] As shown in the drawings, Figures 1-8 A light-weight fixed beam gantry machining center, comprising a fixed beam frame 1 provided with a workbench 11 and a clamp 12, and further comprising a suction accessory 2 arranged between the workbench 11 and the clamp 12, the suction accessory 2 being divided into a lower rubber pad 21 and an upper rubber pad 22 with notches on the end surfaces, and the two notches being connected to form a symmetrically arranged static section 33.

[0037] The static section 33 is provided with cutting fluid.

[0038] A liquid storage section 31 is arranged between the lower rubber pad 21 and the upper rubber pad 22, and the liquid storage section 31 is used to drain the cutting fluid to the static section 33.

[0039] A transfer section 32 is further arranged between the liquid storage section 31 and the static section 33, and the transfer section 32 is provided with a plurality of intercepting members arranged alternately up and down to filter out the cutting fluid.

[0040] Specifically, the workbench 11 belongs to a part of the fixed beam gantry machine tool and is horizontally movable below the fixed beam frame 1, and the clamp 12 is detachably connected to the workbench 11, both of which are prior art and will not be described here.

[0041] Further, the suction accessory 2 is mounted against the clamp 12, so that the clamp 12 can transmit and absorb the vibration force from the suction accessory 2, while keeping the connection between the clamp 12 and the workbench 11 stable.

[0042] Further, the lower rubber pad 21 and the upper rubber pad 22 abut against each other, and the upper end surface of the lower rubber pad 21 is provided with a notch, and the lower end surface of the upper rubber pad 22 is provided with a notch (as shown in Figure 3 and Figure 4 The middle part of the notch of the lower rubber pad 21 is recessed to form a liquid storage cavity 211, and the middle part of the notch of the upper rubber pad 22 is provided with a retention cavity 221, and the side cross section of the upper rubber pad 22 is triangular, and the liquid storage cavity 211 is connected to the retention cavity 221 to form a liquid storage section 31, and the transfer section 32 and the static section 33 are symmetrically arranged on both sides of the liquid storage section 31.

[0043] Further, the workbench 11 is provided with a hole, and the end of the hole and the liquid storage cavity 211 are connected by a wear-resistant rubber hose, and the waste collection and cutting fluid recycling and filtering equipment arranged on one side of the gantry machining center can filter and recycle the cutting fluid, and part of the filtered cutting fluid is diverted to the hole on the workbench 11, so that the filtered cutting fluid can flow into the liquid storage cavity 211 through the hose.

[0044] Further, the upper and lower staggered arrangement of the intercepting members makes the cutting fluid in the transfer section 32 flow in a circular and connected U shape (similar to the arrangement of the condenser pipe of the air conditioner outdoor unit), so that the cutting fluid in the liquid storage section 31 is blocked layer by layer when entering the transfer section 32, thereby reducing the flow rate, so that the cutting fluid entering the static section 33 from the transfer section 32 remains static (the static mode of the liquid is a prior art, which is not described here), and the clamp 12 is located at the bottom of the static section 33, so that the cutting fluid in the suction accessory 2 between the workbench 11 and the clamp 12 has better buffering and adsorption function, avoiding the amplification of resonance caused by the fluctuation of the cutting fluid flow.

[0045] In the above embodiment, the static section 33 can be a rubber capsule, or two plug sheets provided with compressed gas in the middle, or other existing structures or components known to those skilled in the art.

[0046] The cutting fluid in the storage section 31 is slowed down by the multiple intercepting pieces in the transfer section 32, so that the cutting fluid entering the static section 33 is kept static, and the fixture 12 clamps and fixes the part, at this time the tool on the beam frame 1 bores and drills the part, and the vibration source on the part is transmitted to the suction accessory 2 through the fixture 12, at this time the vibration source is transmitted and adsorbed by the double-layered lower rubber pad 21 and upper rubber pad 22, and then transmitted to the workbench 11, so that the workbench 11 can more stably support the suction accessory 2 and the fixture 12, and still keep the effect of stably transmitting and adsorbing the vibration source when there is a gap between the fixtures 12, so as to provide a better vibration source elimination purpose, and the cutting fluid in the static section 33 absorbs the vibration source on the lower rubber pad 21 and upper rubber pad 22, so that the cutting fluid can additionally transmit and absorb the vibration source, so as to greatly reduce the vibration source generated on the part, avoid the part from providing one of the vibration sources in resonance to cause the vibration marks on the machined hole of the part, and improve the part processing yield; and the cutting fluid in the static section 33 can provide better lubrication between the lower rubber pad 21 and upper rubber pad 22, so that the suction accessory 2 is not easily damaged by the wear between the workbench 11 and the fixture 12 during long-time work, has an additional service life compared with the traditional rubber buffer pad, and under the action of the static section 33 which is constantly replaced with cutting fluid, the suction accessory 2 can keep stable adsorption efficiency of the resource transmitted by the fixture 12, so as to realize that the adsorption efficiency of the vibration source will not be reduced due to long-time use of the suction accessory 2, effectively increase the stability of the beam gantry machining center during work, and improve the yield of the production line.

[0047] As a further provided embodiment of the present application, the intercepting pieces are divided into lower intercepting strips 212 and upper intercepting strips 225, and the ends of the two are bent towards each other to block the flow of cutting fluid.

[0048] Specifically, the multiple lower intercepting strips 212 are linearly arrayed and fixedly installed in the notch of the lower rubber pad 21, and abut against the inner wall of the notch of the upper rubber pad 22, and the upper intercepting strips 225 are linearly arrayed and fixedly installed in the notch of the upper rubber pad 22, and abut against the inner wall of the notch of the lower rubber pad 21.

[0049] Further, the lower intercepting strips 212 and the upper intercepting strips 225 are arranged in a staggered manner in the horizontal direction, and the cross sections of the lower intercepting strips 212 and the upper intercepting strips 225 are both in the shape of “J”, and the hook tips of the two are directed towards a point, and there is a gap between the hook tip bending and the notch, so as to make the cutting fluid flow in and bend (as shown in Figure 5

[0050] ​The cutting fluid in the storage section 31 enters the transfer section 32, flows along the back side of the upper intercepting strip 225, and flows into the space between the lower intercepting strip 212 and the upper intercepting strip 225 from the hook tip bending gap of the upper intercepting strip 225. The lower intercepting strip 212 and the upper intercepting strip 225 are arranged oppositely on the hook tip, and the hook tip slows down the cutting fluid. The cutting fluid flows into the space between the lower intercepting strip 212 and the back side of the upper intercepting strip 225 from the hook tip bending gap of the lower intercepting strip 212. The cutting fluid flows into the static section 33 in this way and remains static. The cutting fluid in the static section 33 has a stronger vibration source transmission and absorption effect, avoids the disturbance of the flowing cutting fluid to the absorption of the vibration source, improves the stability of the clamp 12 during operation, and eliminates the high efficiency of the part vibration source.

[0051] The lower intercepting strip 212 and the upper intercepting strip 225 in the above embodiment can be a valve, or a hinged plug that changes the deflection angle when impacted by the liquid flow rate, or a known structure or component known to those skilled in the art.

[0052] As a further embodiment of the present application, a plurality of intercepting holes 213 are formed in the inner side of the lower intercepting strip 212, and a plurality of guide holes 2251 are formed in the upper intercepting strip 225 and arranged opposite to the intercepting holes 213. The guide holes 2251 are used to store the cutting fluid and waste.

[0053] Specifically, the number of intercepting holes 213 corresponds to the number of guide holes 2251, and both are arranged on the inner side of the hook tip of the lower intercepting strip 212 and the upper intercepting strip 225 (as shown in the figure). Figure 8

[0054] The hook tip of the lower intercepting strip 212 and the upper intercepting strip 225 slows down the cutting fluid, so that the small amount of waste particles in the cutting fluid gradually hover, and the waste particles gradually hovering are scraped by the inner wall of the lower intercepting strip 212 and accumulated in the plurality of intercepting holes 213. The cutting fluid after deceleration also allows the waste particles to be stored in large quantities on the inner side of the hook tip of the lower intercepting strip 212 and the upper intercepting strip 225, so that the cutting fluid flowing into the static section 33 does not contain waste particles, and the static section 33 is not disturbed by the waste particles during the vibration source transmission and absorption work, thereby reducing the absorption effect and improving the purity of the cutting fluid in the static section 33, thereby increasing the absorption efficiency of the vibration source of the part transmitted to the clamp 12.

[0055] ​Secondly, when the debris particles are accumulated in the interception hole 213, the synchronous debris particles are also accumulated in the plurality of guide holes 2251, so that the debris particles enter the guide holes 2251 to be stored, the debris particles flowing to the static section 33 are additionally reduced, the stability of the cutting fluid in the static section 33 is ensured, and when the lower rubber pad 21 and the upper rubber pad 22 are removed for cleaning, the debris particles on the lower interception strip 212 and the upper interception strip 225 can be quickly flushed, so that the suction accessory 2 can be repeatedly used, the service life of the suction accessory 2 is additionally increased, and the transmission and adsorption function of the suction accessory 2 on the vibration source is ensured in a long-time working state.

[0056] In the above embodiment, the lower interception strip 212 and the upper interception strip 225 can be filter plates.

[0057] As another embodiment further provided by the application, the lower rubber pad 21 is provided with a hole for conveying gas and liquid, and the inner side of the upper rubber pad 22 is provided with an elastic member 222 abutting and cooperating with the lower rubber pad 21.

[0058] The elastic member 222 separates the gas and the liquid and cooperates with the interception member to form a mixing section 2231 and a drainage section 2232.

[0059] Specifically, one side of the liquid storage cavity 211 injects high-pressure gas (the same as the gas flowing in the gas jet on the tool, which is a prior art and will not be described here), and the other side injects filtered cutting fluid through a rubber hose.

[0060] Further, the elastic member 222 with a cross-section in the shape of a transverse "V" is specifically an elastic metal sheet, and elastic rubber membranes are fixedly installed on both sides of the elastic member 222 (a prior art, which will not be described here), so as to conveniently divide the space in the liquid storage section 31, and the elastic rubber membranes provide the damping required for the deformation of the elastic member 222.

[0061] Further, the upper end of the elastic member 222 is fixedly installed on one side of the retention cavity 221, and the lower end of the elastic member 222 abuts one side of the liquid storage cavity 211 (as shown in Figure 7 Further, a plurality of air holes 223 are formed on the lower side of the elastic member 222, and one-way flaps (a prior art, which will not be described here) are fixedly installed in the air holes 223, so that the gas on the inner side of the elastic member 222 can be injected into the cutting fluid on the outer side of the elastic member 222.

[0062] Further, the mixing section 2231 is at the lower end of the elastic member 222, and the drainage section 2232 is at the upper end of the elastic member 222.

[0063] The lower rubber pad 21 and the upper rubber pad 22 are preliminarily elastically buffered by the elastic member 222 during installation, and the impact force of the cutting fluid sprayed downward from the cutter is buffered and damped under the action of the elastic rubber film arranged on both sides of the elastic member 222, thereby avoiding interference caused by vibration source transmission and absorption of the suction accessory 2, reducing impact damage to the suction accessory 2, and improving the stability and high-efficiency absorption effect of the suction accessory 2 during work.

[0064] Secondly, when the cutting fluid flows into the liquid storage section 31, the cutting fluid is impacted by the sharp apex of the elastic member 222, so as to reduce the flow rate of the cutting fluid in the liquid storage section 31, thereby reducing the flow rate of the cutting fluid entering the transfer section 32, reducing the deceleration workload of the lower intercepting strip 212 and the upper intercepting strip 225 on the cutting fluid, and making the cutting fluid in the transfer section 32 more smoothly decelerate.

[0065] Further, the gas is filled into the liquid storage section 31, the gas inside the elastic member 222 enters the mixing section 2231 from the air hole 223, and the gas and the liquid are mixed in the mixing section 2231, so as to facilitate the gas with pressure to quickly push the cutting fluid into the drainage section 2232, and reduce the interference of the cutting fluid in the liquid storage section 31 with the deceleration work of the intercepting member.

[0066] As a further embodiment of the present application, the upper rubber pad 22 is provided with a main nozzle 224 and a secondary nozzle 2241 which are in communication with the drainage section 2232, and the two nozzles are arranged in a triangular shape with the apex facing away from the workbench 11.

[0067] Specifically, the main nozzle 224 is located at the middle top corner of the upper rubber pad 22, and the plurality of secondary nozzles 2241 are scattered on the middle inclined surface of the upper rubber pad 22, and the main nozzle 224 and the secondary nozzle 2241 are both located on the liquid storage section 31.

[0068] Further, the way of spraying gas and liquid mixture by the main nozzle 224 and the secondary nozzle 2241 is a prior art, which is not described here.

[0069] The gas with pressure quickly pushes the cutting fluid into the drainage section 2232, so that the gas additionally provides the flow rate of the cutting fluid, the main nozzle 224 quickly sprays the mixed liquid to the parts on the clamp 12, and the plurality of symmetrically arranged secondary nozzles 2241 additionally supplement the capacity of upward spraying of the cutting fluid, so that the cutting fluid sprayed downward from the cutter cooperates with the cutting fluid sprayed upward from the main nozzle 224 to realize the up-down double cooling of the machining position of the parts during machining of the parts by the cutter, thereby improving the protection effect during machining of the parts, avoiding the collapse of the parts, and increasing the stability of the clamp 12 during machining of the clamped parts.

[0070] As further provided by the present application, the main nozzle 224 and the sub nozzles 2241 spray cutting fluid for atomized coverage of the fixture 12.

[0071] Specifically, the mixed fluid flow rate sprayed by the main nozzle 224 is greater than that sprayed by the sub nozzles 2241, and the flow rate sprayed by the sub nozzles 2241 gradually decreases as the slope goes downward (as shown by the dotted arrows in the middle slope). Figure 7

[0072] The mixed cutting fluid sprayed by the main nozzle 224 towards the part direction falls after cooling the part and has a return impact effect, making the cutting fluid in an atomized state, and the flow rate of the cutting fluid sprayed away from the part gradually decreases under the action of the multiple symmetrically arranged sub nozzles 2241, so that the atomized range of the cutting fluid sprayed by the multiple sub nozzles 2241 is larger, and the mixed cutting fluid sprayed by the main nozzle 224 in cooperation with the multiple sub nozzles 2241 is in a fan-shaped atomized and dispersed state to cover and protect the surroundings of the fixture 12, so that the cutting fluid with a larger coverage area blows away the large amount of swarf generated during machining of the part, and the large amount of swarf is far away from the fan-shaped atomized cutting fluid, so that the large amount of swarf is dropped on the workbench 11 far away from the fixture 12 under the action of the upward blowing cutting fluid, and the swarf generated during machining of the part does not fall on the upper rubber pad 22 under the downward blowing of the cutting fluid on the tool, thereby effectively reducing the wear and tear of the suction accessory 2 caused by the swarf, increasing the safety of the suction accessory 2 during operation, and improving the vibration source transmission and absorption effect of the suction accessory 2 during long-term use.

[0073] As further provided by the present application, the cutting fluid in the state of covering the fixture 12 cooperates with the part cage arranged on the fixture 12.

[0074] The mixed cutting fluid sprayed by the main nozzle 224 in cooperation with the multiple sub nozzles 2241 is in a fan-shaped atomized and dispersed state to cover and protect the surroundings of the fixture 12, so that the surroundings of the part are filled with atomized cutting fluid, so that the vibration source transmitted to the air during machining of the part can be absorbed by the atomized cutting fluid, the large amount of atomized cutting fluid blocks the transmission of the vibration source to the fixture 12 through the air, and the vibration source is reversely transmitted to the part through the fixture 12, so that the fixture 12 receives less vibration source, the workload of the suction accessory 2 for transmitting and absorbing the vibration source is reduced, and the stability of the fixture 12 during clamping of the part is ensured, thereby additionally reducing the transmission of the vibration source to the air.

[0075] As further provided by the present application, the upper rubber pad 22 is provided with a slope channel 2253 for guiding the cutting fluid in the state of covering the fixture 12.

[0076] Specifically, the slope channel 2253 is arranged on the slope of the upper rubber pad 22 of the transfer section 32, and the slope channel 2253 is arranged in a linear array.​

[0077] The mixed cutting fluid is atomized and dispersed in a fan shape by the cooperation of the main nozzle 224 and the plurality of sub-nozzles 2241, so as to blow away the large amount of swarf generated during the machining of the part. When the atomized cutting fluid flows on the inclined surface of the upper rubber pad 22 after falling, the small amount of swarf carried by the falling cutting fluid flows to the worktable 11 through the inclined surface, so as to facilitate the worktable 11 to collect and process the swarf.

[0078] Secondly, the cutting fluid flowing on the inclined surface carries the swarf into the plurality of inclined flow channels 2253, so that the inclined flow channels 2253 store the falling swarf, reduce the damage caused by the swarf flowing on the inclined surface of the upper rubber pad 22, make the upper rubber pad 22 more durable, and improve the stability of the upper rubber pad 22.

[0079] Furthermore, when the falling cutting fluid impacts the positions of the main nozzle 224 and the sub-nozzles 2241 in the middle of the upper rubber pad 22, the elastic member 222 and the rubber film can buffer the impact, reduce the deformation of the upper rubber pad 22, avoid the interference with the upward spraying of the cutting fluid, keep the mixed cutting fluid in a stable state when being sprayed upward, increase the protection of the part and the clamp 12, and enhance the effect of the atomized cutting fluid on blocking the vibration source of sound propagation.

[0080] As a further embodiment of the present application, the upper intercepting strip 225 is provided with flow slowing holes 2252, and the flow slowing holes 2252 are respectively used to communicate the flow guiding holes 2251 and the inclined flow channels 2253.

[0081] Specifically, the cross section of the flow slowing hole 2252 is trapezoidal, and the smaller bottom surface of the trapezoid is communicated with the inclined flow channel 2253 (as shown in FIG. 8). Figure 8

[0082] ​The waste particles in the transfer section 32 enter the slow flow hole 2252 under the action of the waste particles entering the guide hole 2251 for storage, and the cutting fluid flowing between the lower intercepting strip 212 and the upper intercepting strip 225 enters the guide hole 2251, so that the cutting fluid pushes the waste particles to flow upward, so that the waste particles enter the inclined flow channel 2253, and the upward pushing cutting fluid can mix the waste particles in the transfer section 32 collected in the inclined flow channel 2253 and the waste in the falling cutting fluid, and under the action of the slow flow hole 2252 with a trapezoidal cross section, the upward flowing cutting fluid is not easy to cause the waste particles stored in the inclined flow channel 2253 to flow backward, thereby avoiding the blocking of the slow flow hole 2252, increasing the smoothness of the waste particles during discharge, and under the action of the cutting fluid in the transfer section 32 flowing upward in the inclined flow channel 2253, the mixed waste particles and waste mixture can quickly flow from the upper rubber pad 22 to the workbench 11, realizing the removal of the accumulated waste on the suction accessory 2, facilitating the suction accessory 2 to maintain better vibration source transmission and absorption effect, also reducing the waste particle accumulation during the later removal and flushing of the suction accessory 2, reducing the flushing time and improving the work efficiency.

[0083] As a further embodiment of the present application, the slow flow hole 2252 cooperates with the intercepting member to divide the cutting fluid in the transfer section 32.

[0084] Under the action of the flow rate of the cutting fluid in the transfer section 32 being greater than the flow rate of the cutting fluid on the inclined surface of the upper rubber pad 22, the cutting fluid between the lower intercepting strip 212 and the upper intercepting strip 225 can be divided and enter the slow flow hole 2252, so that the divided cutting fluid on one hand sends out the waste particles, and mixes the waste particles in the inclined flow channel 2253 and sends them to the surface of the workbench 11, and on the other hand, the flow rate of the cutting fluid between the lower intercepting strip 212 and the upper intercepting strip 225 after division is additionally reduced, so that the cutting fluid flowing into the static section 33 can remain in a stable and stationary state, facilitating the cutting fluid to have a better purpose of transmitting and absorbing vibration sources, and increasing the effect of the suction accessory 2 on eliminating resonance during part machining.

[0085] Working principle: through the workbench 11 to the storage cavity 211 and the injection of the retention cavity 221 after the filter cutting fluid, make the cutting fluid in the storage section 31 into the transfer section 32, make the cutting fluid flow along the back side of the upper intercepting strip 225, and flow into the lower intercepting strip 212 and the upper intercepting strip 225 between the hook tip bending gap, make the lower intercepting strip 212 and the upper intercepting strip 225 on the hook tip of the opposite arrangement of cutting fluid flow resistance deceleration, and then flow into the lower intercepting strip 212 and the upper intercepting strip 225 back by the lower intercepting strip 212 hook tip bending gap, in this way to make the cutting fluid flow into the static section 33 when keep still, and the fixture 12 clamping fixed parts, at this time the tool on the beam frame 1 on the parts drilling and boring process, and make the parts on the vibration source through the fixture 12 and transmitted to the suction member 2, at this time the vibration source through the lower rubber pad 21 and the upper rubber pad 22 double layer transmission adsorption, and then transmitted to the workbench 11, so that the workbench 11 can provide more stable support to the suction member 2 and the fixture 12, make the fixture 12 between the gap still can keep stable transmission adsorption vibration source effect, to provide better vibration source elimination purpose, and the cutting fluid in the static section 33 will be transmitted to the lower rubber pad 21 and the upper rubber pad 22 on the vibration source liquid absorption, so that the cutting fluid can additional transmission absorption of vibration source, in order to greatly reduce the vibration source generated on the parts, avoid the parts to provide one of the vibration source and cause the parts processing hole appear shake the situation of note.

[0086] Secondly, the lower intercepting strip 212 and the upper intercepting strip 225 on the hook tip of the opposite arrangement of cutting fluid flow resistance deceleration, to make the cutting fluid between the two deceleration and promote the gradual suspension of the small amount of cutting fluid in the waste particles, and make the gradually suspended waste particles are scraped by the inner wall of the lower intercepting strip 212 and accumulated in the plurality of intercepting holes 213, at the same time, the deceleration of the cutting fluid can also make the waste particles are stored in the lower intercepting strip 212 and the upper intercepting strip 225 hook tip inside, so that the cutting fluid flowing into the static section 33 does not contain waste particles, improve the purity of the cutting fluid in the static section 33, and the waste particles are accumulated in the intercepting hole 213, the synchronous waste particles will also be accumulated in the plurality of guide holes 2251, so that the waste particles enter the guide hole 2251 and are stored, additional reduce the waste particles flowing into the static section 33.

[0087] Furthermore, the cutting fluid flowing into the storage section 31 is impacted by the sharp tip of the elastic member 222, so as to reduce the flow rate of the cutting fluid in the storage section 31, thereby reducing the flow rate of the cutting fluid into the transfer section 32. The gas is filled into the storage section 31, so that the gas inside the elastic member 222 flows into the mixing section 2231 through the vent hole 223, and the gas and the liquid are mixed in the mixing section 2231. The gas with pressure can quickly push the cutting fluid into the drainage section 2232, so that the gas provides an additional cutting fluid ejection flow rate. The main nozzle 224 can quickly spray the mixed liquid to the part on the clamp 12, and the additional upward ejection capacity of the cutting fluid is supplemented by the symmetrically arranged multiple sub-nozzles 2241. During the machining of the part by the tool, the downward ejection of the cutting fluid on the tool is matched with the upward ejection of the cutting fluid by the main nozzle 224 to achieve the upward and downward double cooling of the machining position of the part, thereby improving the protection effect during the machining of the part. The mixed cutting fluid sprayed by the main nozzle 224 and the multiple sub-nozzles 2241 is in a fan-shaped atomized and scattered state, so as to cover and protect the surrounding of the clamp 12. The surrounding of the part is filled with atomized cutting fluid, so that the vibration source transmitted to the air during the machining of the part can be absorbed by the atomized cutting fluid. A large amount of atomized cutting fluid can block the transmission of the vibration source to the clamp 12 through the air, and the vibration source is reversely transmitted to the part through the clamp 12, so that the clamp 12 receives less vibration source, and the work load of the suction accessory 2 for absorbing the vibration source is reduced.

[0088] Finally, the mixed cutting fluid sprayed by the main nozzle 224 and the multiple sub-nozzles 2241 is in a fan-shaped atomized and scattered state, so as to blow away a large amount of waste generated during the machining of the part. When the atomized cutting fluid flows on the inclined surface of the upper rubber pad 22, a small amount of waste carried by the descending cutting fluid flows to the workbench 11 through the inclined surface. The waste particles enter the flow guide hole 2251 for storage. The waste particles in the transfer section 32 enter the buffer hole 2252 and flow between the lower intercepting strip 212 and the upper intercepting strip 225. Under the action of the cutting fluid entering the flow guide hole 2251, the cutting fluid pushes the waste particles to flow upward, so that the waste particles enter the inclined flow channel 2253. The upward pushing of the cutting fluid can mix the waste particles in the transfer section 32 collected in the inclined flow channel 2253 and the waste in the falling cutting fluid. Under the action of the cutting fluid in the transfer section 32 flowing upward in the inclined flow channel 2253, the mixed waste particles and waste mixture can quickly flow from the upper rubber pad 22 to the workbench 11, so as to remove the waste accumulated on the suction accessory 2, and facilitate the suction accessory 2 to maintain better vibration source transmission and absorption effect.
