Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 14, a cutting device for a fixture includes: a cutting unit 1 for cutting a workpiece according to a set trajectory by discharging an electrode; a liquid supply unit 2 for supplying a cooling liquid to at least the position where the electrode is located, and circulating the cooling liquid; the filter unit 3 is provided in the circulation path of the coolant, and filters the coolant.

The filter unit 3 includes: the drum-shaped filter assembly comprises two bowl-shaped structures 31 which are symmetrically arranged, and the edges of the two bowl-shaped structures 31 are bonded to form two convex outer guide surfaces 31a and two convex inner guide surfaces 31b; a power assembly 32 for providing rotational power to the drum-shaped filter assembly so that the central ranges of the two outer guide surfaces 31a are rotated to the falling position of the cooling liquid; a valve body 33 mounted in the central range of the bowl-shaped structure 31, the valve body 33 being closed when the bowl-shaped structure 31 is downward in the bowl mouth and being opened when the bowl-shaped structure 31 is upward in the bowl mouth; a collecting tank 34 for rotatably supporting the drum-shaped filter assembly and collecting the chips dropped from the outer guide surface 31a, the bottom of the collecting tank 34 having a guide pipe 34a directed upward for the outflow of the cooling liquid from the filter unit 3; wherein, the outer diversion surface 31a surrounds the axis and is provided with a plurality of circles of concave flow blocking grooves 31c from inside to outside, and a plurality of through holes 31d are uniformly distributed in the flow blocking grooves 31 c.

Any shape that can achieve the filtering of the machining chips can be applied to the present invention, and it is only necessary to ensure that the cooling liquid can smoothly enter the drum-shaped filter assembly.

In the invention, the jig cutting device capable of always ensuring the cleanliness of the electrode is provided, the device can ensure the machining precision of the jig on one hand and prolong the service life of the jig on the other hand, and more importantly, the filter structure capable of keeping the cleanliness can realize self-cleaning, does not need frequent cleaning or replacement, and can always keep a stable state of effectively filtering machining scraps.

Specifically, as shown in fig. 1 to 4 and 8, during the process of cutting a workpiece, the electrode and the workpiece are moved relatively, and during the process, the stability of the cooling liquid supply position needs to be ensured, so that timely cleaning of machining scraps and cooling of a high-temperature position are always kept; during the process of falling from the above position, the cooling liquid falls to the center of the outer guide surface 31a of one of the bowl-shaped structures 31, at this time, the bowl-shaped structure 31 faces downward and the valve body 33 is closed, so that the cooling liquid flows in a divergent shape around.

In this process, when the cooling liquid carrying the processing scraps passes through each stage of flow blocking grooves 31c, the processing scraps are blocked into the flow blocking grooves 31c to a certain extent, meanwhile, the cooling liquid with impurities removed can flow into the drum-shaped filter assembly from the through holes 31d, and in this process, the cooling liquid can naturally flow downwards to the valve body 33 along the inner flow guiding surface 31b of the bottom bowl-shaped structure 31, and the valve body 33 at this position is opened due to the upward direction of the bowl-shaped structure 31, so that the filtered cooling liquid can continuously flow downwards to participate in subsequent circulation.

It should be noted that, the position that the drum-shaped filter assembly needs to reach under the driving of the power assembly 32 is a horizontal position of the symmetry planes of the two bowl-shaped structures 31, so that the bowl-shaped structures 31 can be controlled stably by the power assembly 32 in a manner that the bowl mouths of the bowl-shaped structures 31 face upwards or downwards, and the valve body 33 can be opened and closed effectively.

When the cooling liquid flows through the bowl-shaped structure 31 at the top, the cooling liquid falls into the bowl-shaped structure 31 at the bottom through the through hole 31d, and in this case, the cooling liquid can quickly flow to the valve body 33 at the bottom along the side wall of the bowl-shaped structure 31, so that the cooling liquid can be quickly discharged; since the inner wall of the bottom bowl-shaped structure 31 protrudes downward, the guiding of the cooling liquid is quick, the probability that the cooling liquid penetrates through the through hole 31d of the bottom bowl-shaped structure 31 is low, or even if part of the cooling liquid penetrates through the through hole 31d, the processing scraps in the flow blocking groove 31c rotating from the top to the bottom can be acted, so that the processing scraps can fall down due to gravity and can enter the collecting groove 34 through the action of a small amount of cooling liquid, and the cleaning purpose is realized.

In the above process, during the rotation of the drum-shaped filter assembly, the machining scraps can be partially dropped in the rotation process, and after the rotation, the gravity effect can also realize the secondary cleaning of the machining scraps, and part of cooling liquid and the machining scraps are gathered in the collecting tank 34, so that the cleaning can be intensively obtained.

As a preference to the above embodiment, the valve body 33 includes: the mounting seat 33a is fixedly connected with the bowl-shaped structure 31 and is provided with a groove 33a-1, and the center of the bottom of the groove 33a-1 is a through area 33a-2; the limiting seat 33b comprises a ring body 33b-1 and a limiting edge 33b-2, wherein the ring body 33b-1 is coaxially arranged, the limiting edge 33b-2 is vertically connected with one end of the ring body 33b-1, the ring body 33b-1 is at least partially arranged in the groove 33a-1, and one end edge of the limiting seat is vertically connected with the edge of the through region 33a-2; the switch seat comprises a seat body 33c for the ring body 33b-1 to fit and penetrate, and for accommodating the limit edge 33b-2, wherein the seat body 33c is provided with an open end; the device further comprises a flow-through plate 33d for plugging the open end, and a plurality of hole sites 33d-1 are arranged on the flow-through plate 33 d.

The switch seat is disposed in free movement along the axial direction relative to the ring body 33b-1, and the hole site 33d-1 is closed when the current passing plate 33d is attached to the limit edge 33b-2 and opened when the current passing plate and the limit edge are separated.

As shown in fig. 5 to 7 and 9 to 11, the structure and the working form of the valve body 33 are shown, and in the process of installing the valve body, the valve body can be preassembled first, and then installed integrally with respect to the bowl-shaped structure 31 after being preassembled as a whole; referring to fig. 5, there is shown an exploded schematic view of the various structures, to facilitate assembly of the above structures, the following optimizations may be made:

in the first aspect, an inner ring of the through region 33a-2 of the mounting seat 33a is provided with an inner thread, and an outer wall of the end part of the ring body 33b-1 is provided with an outer thread; the mount 33a is screwed with the ring 33 b-1. That is, the connection between the mounting seat 33a and the limit seat 33b is performed by screw connection, so that the mounting seat 33a and the limit seat 33b are convenient to disassemble and reassemble, and the limit seat 33b can be quickly fixed relative to the mounting seat 33a after the limit seat 33b is mounted relative to the seat body 33 c.

In the second aspect, the inner wall of the open end of the base 33c is provided with internal threads, and the edge of the flow-through plate 33d is provided with external threads; the seat body 33c is connected with the overflow plate 33d through threads; that is, for the connection between the flow-through plate 33d and the base 33c, the same applies a screw connection method, and after the limit base 33b is mounted on the base 33c, the flow-through plate 33d can be quickly fixed on the base 33 c.

As a preference to the above embodiment, referring also to fig. 5, the valve body 33 further includes an elastic pad 33e attached to the limit edge 33b-2, the elastic pad 33e being disposed between the flow-through plate 33d and the limit edge 33 b-2.

Referring to fig. 6, 7 and 9, when the valve body 33 is positioned at the top, the whole switch seat moves linearly relative to the ring body 33b-1, and falls to a position where the flow-through plate 33d is attached to the limit edge 33b-2, so that the hole site 33d-1 is blocked by the limit edge 33 b-2; in this state, when the coolant falls to the surface of the flow-through plate 33d, it cannot pass through the hole site 33d-1 to reach the middle of the ring body 33b-1, thereby entering the inside of the drum-shaped filter assembly; the cooling liquid can be filtered only by circulating the cooling liquid around the drum-shaped filter assembly through the through holes 31d in the blocking groove 31 c.

Referring to fig. 10 and 11, when the valve body 33 is at the bottom, the whole switch seat moves linearly relative to the ring body 33b-1, and falls to a position where the flow-through plate 33d is separated from the limit edge 33b-2, and at this time, the side wall of the seat body 33c, through which the ring body 33b-1 passes, is attached to the back surface of the limit edge 33b-2, and the flow-through plate 33d is separated from the limit edge 33 b-2; in this state, when the coolant falls to the surface of the flow-through plate 33d through the center of the ring body 33b-1, the coolant flows out of the drum-shaped filter assembly through the hole 33d-1 of the flow-through plate 33d, thereby participating in the subsequent recycling.

In the above process, the sealing performance between the limit edge 33b-2 and the overflow plate 33d can be effectively improved by using the elastic pad 33e, and the combination structure of the overflow plate 33d and the seat body 33c has a certain weight, so that the elastic pad 33e can be deformed when being pressed, thereby effectively improving the sealing performance; the connection between the elastic pad 33e and the limit edge 33b-2 is preferably performed by bonding, and of course, other ways of ensuring stable connection are also within the scope of the present invention.

In the above-described optimization, in order to ensure the stability of the fixing of the mounting seat 33a with respect to the bowl-shaped structure 31, a rim structure may be provided to increase its contact area with respect to the bowl-shaped structure 31.

As a preference to the above-described embodiment, the bowl-like structure 31 is a plastic structure, the structure of which has at least the following advantages:

(1) The plastic structure is light in weight, the work load of the power assembly 32 is small, and more flexible rotation can be realized;

(2) The product cost is low, the choke groove 31c can be directly formed, and the choke groove and the through hole 31d can be obtained through subsequent processing, and a small amount of processing can be realized through a rapid forming mode;

(3) The shape stability is good, and the stable form can be ensured through larger hardness as the metal material, thereby realizing effective filtration.

In an optimized way for the bowl-like structure 31, the inner wall of the bowl-like structure 31 is a smooth surface, which is more advantageous for the flow guiding after the cooling liquid has fallen down, as shown in fig. 12.

As a preferred embodiment, the power assembly 32 includes two semicircular clasps 32a, and the two semicircular clasps 32a symmetrically wrap around the edges of the two bowl-shaped structures 31; the device also comprises two fixing seats 32b which are respectively connected with at least two semicircular clamping rings at the joint of the two semicircular clamping rings 32 a; the fixing bases 32b are rotatably connected with the collecting tank 34, and one of the fixing bases 32b is led out of the collecting tank 34 to be connected with the motor 32 c.

The fixing of the two bowl-shaped structures 31 can be more convenient by the structure, and the transmission of the rotation power is more effective. In order to ensure the stability of the bowl-shaped structure 31 fixed relative to the semicircular clamping ring 32a, a flat edge can be arranged at the edge of the bowl-shaped structure 31, so that the fixation is more stable; the fixation of the semicircular clasp 32a relative to the bowl-shaped structure 31 can be achieved only by the above-mentioned cladding, however, the bowl-shaped structure 31 may rotate relative to the semicircular clasp 32a in this way, but the implementation of the filtering process is not affected; when the rotation is to be avoided, the connection between the two semicircular snap rings 32a can be established, the connection between the semicircular snap ring 32a and the fixing seat 32b can be established, and the bowl-shaped structure 31 can be fixed relative to the semicircular snap ring 32a, and the fixation can be realized through the use of the connecting piece.

As a preference to the above embodiment, as shown in fig. 14, to facilitate cleaning of the interior of the collection tank 34, the collection tank 34 includes a main body 34b and a bottom cover plate 34c, the bottom cover plate 34c being detachably connected to the main body 34 b; the draft tube 34a is disposed on the bottom cover plate 34 c.

In this way, after a certain amount of coolant and machining chips are collected at the bottom of the collection tank 34, the bottom cover plate 34c can be quickly cleaned by removing the bottom cover plate, and the cleaning thoroughness is ensured; the height of the guide tube 34a determines the limit collection amount of the machining chips and part of the cooling liquid in the collecting tank 34, and the guide tube 34a and the bottom cover plate 34c can be arranged in an adjustable mode, so that the selection of the height is convenient. In order to secure the sealability of the above structure, a sealing ring may be provided between the bottom cover plate 34c and the body 34b, thereby avoiding leakage of the cooling liquid.
