[0029] The specific embodiments of the utility model are described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0030] The machining protective device and chip removal system of the utility model are described below with reference to the drawings.

[0031] As Figure 1 shown, the utility model provides a machining protective device, wherein the machining protective device comprises:

[0032] The fixed baffle 1 is fixedly arranged on the first side of the processing machine table 4 and extends along the length direction of the processing machine table 4.

[0033] The movable baffle assembly 2 is arranged on the upper side of the processing machine table 4 and is arranged in opposite and spaced relation with the fixed baffle 1, and the movable baffle assembly 2 is movably arranged towards the direction away from or close to the fixed baffle 1, so that the workpiece positioning area 41 on the processing machine table 4 is switched between the exposed material placing state and the protective machining state.

[0034] When the above machining protective device is used, the fixed baffle 1 is arranged on the first side of the processing machine table 4 and extends along the length direction of the processing machine table 4, so as to surround the splashed chips on the first side of the processing machine table 4, and the movable baffle assembly 2 is arranged on the upper side of the processing machine table 4 and is arranged in opposite and spaced relation with the fixed baffle 1, when the movable baffle assembly 2 is moved to the position close to the fixed baffle 1, the workpiece positioning area 41 on the processing machine table 4 is in the exposed material placing state, that is, the workpiece positioning area 41 is located on the outer side of the movable baffle assembly 2, and the operating personnel or mechanical transfer equipment can place the workpiece on the workpiece positioning area 41 without obstruction, when the movable baffle assembly 2 is moved to the position away from the fixed baffle 1, the workpiece positioning area 41 on the processing machine table 4 is in the protective machining state, that is, the workpiece positioning area 41 is located between the movable baffle assembly 2 and the fixed baffle 1, and the chips splashed to both sides of the processing machine table 4 during machining are respectively surrounded by the movable baffle assembly 2 and the fixed baffle 1, so as to ensure that the chips will not fall on other equipment or manual passage, and the safety during machining is improved.

[0035] It needs to be particularly pointed out that the kind of mechanical processing includes: cutting processing, grinding processing, drilling processing and the like, wherein the cutting processing includes turning, milling, planing and the like, these processing modes all can produce the chippings, and the workpiece is generally the iron material product, so the produced chippings are iron filings, the mechanical processing protection device of the utility model is suitable for being used on the machine tool of various mechanical processing, and is especially suitable for being used on the machine tool of milling processing.

[0036] As shown in Figure 1 and Figure 2 , in the utility model embodiment, the movable baffle assembly 2 includes a movable baffle 21, the movable baffle 21 is movably arranged towards the direction away from or close to the fixed baffle 1, and the movable baffle 21 is used to form a avoiding gap 22 on the position corresponding to the workpiece positioning area 41 towards one end of the processing machine table 4.

[0037] Specifically, referring to Figure 1 and Figure 3 , the middle position of the processing machine table 4 is sequentially arranged with a plurality of workpiece positioning areas 41, the workpiece positioning area 41 is provided with corresponding fixed structure to prevent the workpiece from moving in the processing process, the avoiding gap 22 is formed in the middle area of one end of the movable baffle 21 towards the processing machine table 4, after placing the workpiece or taking out the workpiece, the movable baffle 21 needs to be moved, then the avoiding gap 22 can make the movable baffle 21 pass through the upper side of the workpiece smoothly, and the part of the movable baffle 21 on the both sides of the avoiding gap 22 can be arranged to be attached to the table surface of the processing machine table 4, in the process of moving the movable baffle 21 towards the fixed baffle 1, the movable baffle 21 can also clean the chippings in the other areas of the table surface except the workpiece positioning area 41.

[0038] Of course, the utility model is not limited to, in other specific embodiments, the avoiding gap 22 can also be cancelled, the lower end surface of the movable baffle 21 is arranged as a plane, and a certain spacing is kept with the table surface of the processing machine table 4, the movable baffle 21 can also pass through the upper side of the workpiece smoothly.

[0039] In the embodiment of the utility model, the movable baffle assembly 2 further includes a gap cover arranged on the movable baffle 21, and the gap cover can swing between opening and covering the avoiding gap 22. It can be understood that the arrangement of the avoiding gap 22 can make the movable baffle 21 pass through the workpiece smoothly, but also can cause some chips produced by machining to fly out from the avoiding gap 22. Therefore, the gap cover can stop the chips splashing towards the avoiding gap 22, ensure the safety in the machining process, and the gap cover can be swing arranged. When the movable baffle 21 passes through the workpiece, the gap cover contacts the workpiece and swings upward under the action of the workpiece, so as to open the avoiding gap 22. After the movable baffle 21 passes through the workpiece, the gap cover swings downward under the action of its own gravity, so as to cover the avoiding gap 22, which ensures the blocking effect of the chips and does not affect the movable baffle 21 passing through the workpiece.

[0040] In the embodiment of the utility model, the gap cover is arranged as a soft workpiece, and the gap cover deforms to swing upward after contacting the workpiece, so as to open the avoiding gap 22. On the one hand, the gap cover arranged as a soft workpiece has the advantages of convenient installation, and the gap cover can be quickly replaced by arranging a quick-change socket on the movable baffle 21; on the other hand, the soft gap cover can be compatible with machining of parts of different thicknesses, and good protection effect can be achieved when milling parts of different thicknesses. In addition, the gap cover can also be installed on the movable baffle 21 by means of pasting or bolt fixing.

[0041] Of course, the utility model is not limited to this, and the gap cover can also be arranged as a hard material. Correspondingly, a lifting mechanism needs to be arranged on the movable baffle 21, and the lifting mechanism is drivingly connected with the gap cover, so as to drive the gap cover to open or close the avoiding gap 22.

[0042] Further, the gap cover is arranged as a transparent material workpiece, and an operator can observe the position of the machining device 8 through the gap cover. If the gap cover is arranged as a soft workpiece, the soft curtain made of PVC can be preferably selected; if the gap cover is arranged as a hard material, the acrylic plate can be preferably selected.

[0043] Still further, if the machining machine table 4 itself is too long, a steel framework can be additionally arranged on the movable baffle 21 to prevent deformation, and a lifting driven pulley can also be arranged between the movable baffle 21 and the middle part of the machining machine table 4 to play a supporting and auxiliary moving role.

[0044] For example, Figure 1 and Figure 2As shown, in the embodiment of the utility model, the protection device for machining further includes two fixed end plates 3, the two fixed end plates 3 are separately arranged at opposite ends of the machining platform 4, and the movable baffle assembly 2 further includes a sliding drive element 23 arranged on the fixed end plate 3, and the driving end of the sliding drive element 23 is drivingly connected with the movable baffle 21. The fixed end plate 3 can on the one hand laterally enclose the machining platform 4, and the fixed baffle 1, the movable baffle 21 and the two fixed end plates 3 enclose the workpiece positioning area 41, further preventing debris from flying out, and on the other hand, by arranging the sliding drive element 23 on the fixed end plate 3, the automatic control of the movable baffle 21 can be realized.

[0045] Specifically, the sliding drive element 23 can be arranged on both of the two fixed end plates 3, or the sliding drive element 23 can be arranged on one of the two fixed end plates 3.

[0046] Further, by additionally arranging a sensor and a control device (such as a computer or a single-chip microcomputer), the equipment can easily determine the current machining process, the control device controls the sliding drive element 23 to appropriately adjust the action and dynamics of the movable baffle 21, and the operator only needs to perform the same action as when operating the traditional equipment, without increasing the operation difficulty and reducing the learning cost.

[0047] In the embodiment of the utility model, the sliding drive element 23 is arranged as a telescopic drive element, the movable baffle assembly 2 further includes a slide rail 24 arranged on the fixed end plate 3, the slide rail 24 extends along the width direction of the machining platform 4, and the movable baffle 21 is provided with a sliding block part 25 movable along the slide rail 24. The slide rail 24 provides a guide for the movement of the movable baffle 21, and ensures the smooth movement of the movable baffle 21.

[0048] Specifically, the slide rail 24 includes a mounting seat and a guide rod, the mounting seat is arranged on the fixed end plate 3, the guide rod is arranged on the mounting seat and extends along the width direction of the machining platform 4, and the sliding block part 25 is formed with a guide hole through which the guide rod passes. It can be understood that the debris generated during the machining process may splash towards the slide rail 24, but since the guide rod is in a cylindrical structure, the debris is difficult to adhere to the guide rod, thereby ensuring that the movement of the sliding block part 25 is not affected, and for the slide rail 24 with a conventional sliding groove structure, the debris is easy to accumulate in the sliding groove.

[0049] Preferably, the telescopic drive element is arranged as a pneumatic cylinder, and by arranging an electromagnetic valve, the movement of the movable baffle 21 can be conveniently controlled.

[0050] Of course, the utility model is not limited to this, and the telescopic drive element can also be arranged as a hydraulic cylinder, an electric push rod or other forms. Even the sliding drive element 23 can also be arranged as a pulley mechanism, a ball screw mechanism or other forms.

Then the chip generated in the processing process can be cleaned from processing machine platform 4, and the guide part guides the chip to the lower side of the processing machine platform 4, so that the corresponding chip collecting device can be conveniently arranged on the lower side of the processing machine platform 4, to avoid the chip collecting device from occupying additional space, and improve the overall space utilization.

[0052] In the embodiment of the utility model, the inclination angle of the guide part along the vertical direction is 25°-35°, that is, it ensures that the chip can be smoothly guided to the lower side of the processing machine platform 4, and also ensures that the chip will not accumulate on the guide part.

[0054] Specifically, the chip collecting device 6 can be movably arranged, and can be arranged to notify the automatic guided vehicle (AGV) to intelligently carry when the chip accumulates to a certain height or weight, and the form of the chip removal machine 5 can be arranged in the form of chain plate, conveying plate chain, dense tank chain, etc.

[0055] In the embodiment of the utility model, the chip removal system further comprises a mounting trench 7, which is arranged on the ground below the processing machine platform 4, the inlet end of the chip removal machine 5 is arranged in the mounting trench 7, and the outlet end of the chip removal machine 5 extends out of the mounting trench 7. By arranging the mounting trench 7 below the processing machine platform 4 and arranging the chip removal groove at the inlet end of the chip removal machine 5 in the mounting trench 7, the outlet end of the chip removal machine 5 extends out of the mounting trench 7, so as to pour the chip from above the chip collecting device 6, effectively utilize the space below the processing machine platform 4, and reduce the floor area occupied by the chip removal system.

[0056] Specifically, taking edge milling as an example, the working process of the above-mentioned chip removal system is described:

[0057] Preparation before processing: when the previous workpiece processing is completed or the system detects that there is no workpiece to be processed on the workpiece positioning area 41, the movable baffle 21 will be driven by the sliding driving element 23 to move along the sliding rail 24 to the fixed baffle 1, so as to completely leave the workpiece positioning area 41, thereby facilitating the feeding of the workpiece;

[0058] Processing process: when the workpiece is fed, positioned and fixed in the workpiece positioning area 41, the movable baffle 21 will be driven by the sliding driving element 23 to move away from the fixed baffle 1 along the sliding rail 24 to a preset position, so as to prepare for the prevention of splashing; when the processing device 8 starts milling operation, the chip removal machine 5 is started synchronously, and the iron chips will be guided to fall into the chip removal machine 5 under the action of the protection device during the edge milling process, and the plate chain in the chip removal groove in the chip removal machine 5 drives the iron chips to be collected into the chip collecting device 6;
