Description

Technical Field

[0001] The utility model relates to the technical field of lathes, in particular to a lathe chip baffle cover body. Background Art

[0002] In the field of lathes, although CNC lathes have advantages in improving efficiency and reducing human errors in recent years, ordinary lathes still have advantages in terms of low processing cost, suitability for small-batch production, and easy maintenance. Therefore, it is difficult for ordinary lathes to be completely replaced. However, the rotating, feeding and other parts of ordinary lathes are exposed. During the machining process, chips will fly out along the rotation direction of the spindle and sometimes splash onto the operator, which is likely to cause harm to the operator. In addition, during the operation of ordinary lathes, there is also a phenomenon of coolant splashing. The coolant often contains chips and is also likely to harm the operator.

[0003] Therefore, during the development of ordinary lathes, various lathe protection devices have emerged. These protection devices are generally fixedly or movably installed on the lathe base, lathe carriage (i.e., the structure for setting or moving the tool rest) or the ground around the lathe. Some of them also have a folding function. Although the protection effect is good, on the one hand, most of them can only play a protective role and lack a certain chip collection function, so a large amount of chips will still accumulate on or near the lathe. On the other hand, they occupy the space of the lathe or the ground, or in other words, they squeeze the operation space, which to a certain extent affects the operation of the lathe or the cleaning work of the lathe. Finally, and more importantly, some substances such as chips and coolant will inevitably adhere to their protection surfaces. If these substances cannot be cleaned up or properly stored as much as possible, during their folding, moving and other movements, these substances remaining on the protection surfaces are likely to fall off and splash everywhere, which not only increases the burden of secondary cleaning, but also may affect the normal operation of the lathe or cause unnecessary harm to the operator. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a lathe chip baffle cover body, which solves the problems existing in the prior art that the lathe protection device lacks a chip collection function, will squeeze the operation space, and the chips and other substances remaining on its protection surface are easy to fall off, thus bringing unnecessary troubles.

[0005] According to an embodiment of the utility model, a lathe chip baffle cover body includes a cover body, a lifting assembly and a scraping assembly; wherein,

[0006] The cover body includes:

[0007] A top cover, the top cover is in an inverted V shape and baffles extending obliquely downward are provided at both ends thereof;

[0008] Side covers, there are two side covers which are arranged facing each other under the inner side of the top cover, there is a movable space between the two side covers and the top cover, and there is a blanking space reserved between the two side covers and the corresponding baffles;

[0009] Side collecting baskets, there are two side collecting baskets and the two side collecting baskets are respectively connected to the bottom sides of the facing surfaces of the two side covers;

[0010] Top collecting baskets, there are two top collecting baskets and the two top collecting baskets are respectively connected to the bottom sides of the back surfaces of the two side covers, and the two top collecting baskets also respectively correspond to the positions below the two blanking spaces and are communicated;

[0011] The lifting assembly is connected to the top cover;

[0012] The scraping assembly is slidably attached to the top cover and is used to scrape the iron filings adhered to the inner wall of the top cover into the blanking space.

[0013] The technical principle of the present utility model is as follows:

[0014] During use, first start the lathe and when the lathe runs stably, start the lifting assembly to lower the cover body to a suitable position, and then turn off the lifting assembly; during the cutting of the lathe, part of the flying iron filings and coolant fall into the side collecting baskets, part fall on the lathe or the ground, and a small amount adheres to the protective surface of the iron filings shielding cover body of the lathe, thus avoiding harm to the operator;

[0015] When stopping use, after the lathe processing is completed, use the scraping assembly to scrape off the iron filings or coolant adhered to the inner wall of the top cover, and the scraped iron filings or coolant finally fall into the top collecting basket through the blanking space, and then start the lifting assembly to lift the cover body up. In addition, the iron filings remaining on the edge of the cover body or the scraping assembly can always fall into the top collecting basket through the blanking space during the rising or hanging process, ensuring the safety of the operator below.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] 1. Through the lifting design, it avoids occupying the space of the lathe or the ground when installing or placing the iron filings shielding cover body of the lathe, that is, it avoids squeezing the operation space, and greatly facilitates the operation of the lathe or the cleaning work of the lathe.

[0018] 2. Through the cooperation of the scraping assembly with the side collecting baskets and the top collecting baskets, combined with the functions of the movable space and the blanking space, the iron filings, coolant and other substances adhered and remaining on the top cover can be scraped off and finally fall into the top collecting basket, ensuring the safety of the operator; even if there are still remaining substances on the edge of the top cover or the scraping assembly, during the rising, falling or hanging process of the cover body, these remaining substances can only fall into the blanking space and then into the top collecting basket, further ensuring the safety of the operator.

[0019] 3. By using a side collection basket to collect a certain amount of iron filings, it not only reduces the subsequent cleaning work of the iron filings but also prevents substances such as iron filings adhering to the corresponding protective surface of the side cover from slipping, thus further ensuring the safety of the operators.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0028] As Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a lathe chip baffle cover, which includes a cover body, a lifting assembly and a scraping assembly; wherein, the cover body includes a top cover, side covers 200, side collecting baskets 500 and top collecting baskets 600; the top cover is in an inverted V shape and baffles 130 extending obliquely downward are provided at both ends thereof; there are two side covers 200 which are arranged oppositely below the inner side of the top cover, and an activity space 300 is left between each of the two side covers 200 and the top cover, and a blanking space 400 is reserved between each of the two side covers 200 and the corresponding baffle 130; there are two side collecting baskets 500 and the two side collecting baskets 500 are correspondingly connected to the bottom sides of the opposite faces of the two side covers 200; there are two top collecting baskets 600 and the two top collecting baskets 600 are correspondingly connected to the bottom sides of the opposite faces of the two side covers 200, and the two top collecting baskets 600 also correspond to the lower parts of the two blanking spaces 400 and are communicated; the lifting assembly is connected to the top cover; the scraping assembly is slidably attached to the top cover and is used to scrape the chips adhered to the inner wall of the top cover into the blanking space 400.

[0029] In an embodiment of the present utility model, specifically:

[0030] The side covers 200 and the baffles 130 are preferably made of transparent and high-temperature resistant materials; the widths of the top cover and the side covers 200 should be appropriate, and the specific width is preferably such that after completely covering the working area required for cutting a general-length workpiece on a lathe (mainly referring to an ordinary horizontal lathe) (i.e., the corresponding area between the workpiece clamping end and the workpiece processing end), there is still a certain surplus; the side covers 200 are preferably arranged obliquely, and the space enclosed by the two side covers 200 is narrow at the top and wide at the bottom; preferably, the opening sizes of the side collecting baskets 500 and the top collecting baskets 600 should satisfy that the chips vertically falling from the corresponding top cover areas of the side covers 200, the blanking space 400 or the side collecting baskets 500 can all completely enter the corresponding side collecting baskets 500 or top collecting baskets 600; after the baffle 130 extends obliquely downward, the distance between it and the corresponding side cover 200 gradually decreases from top to bottom, that is, the blanking space 400 is wide at the top and narrow at the bottom; the top cover and the side covers 200 can be connected by a connecting rod 131, and the connecting rod 131 is preferably placed within the blanking space 400 and its radial dimension is as small as possible so as to facilitate the free passage of chips and the like through the blanking space 400. Of course, the connections between the connecting rod 131 and the top cover and the side covers 200 are preferably detachable connections to facilitate cleaning or maintenance. In addition, the "inner wall of the top cover" mainly refers to the wall surface of the top cover that can directly contact the chips, and it is a part of the protective surface of the entire cover body.

[0031] So far, the space enclosed by the entire cover is spacious enough to facilitate the cover to play its shielding role without interfering with the operation of the lathe. The size of the side collection basket 500 can also be made as large as possible for better storage. The inclined baffle 130 can, when at a relatively low height, preferably drain iron filings and the like to the side cover 200 so that the iron filings and the like slide down along the side cover 200 into the top collection basket 600. Coupled with the baffle 130 and the side cover 200 made of a transparent material, especially the part of the side cover 200 corresponding to the area between the baffle 130 and the top collection basket 600 being made of a transparent material, it can provide good visual operation conditions for the operator.

[0032] In the embodiment of the present utility model:

[0033] On the one hand, through the lifting design, it is avoided that the installation or placement of the lathe iron filings shielding cover occupies the space of the lathe or the ground, that is, it avoids squeezing the operation space, which greatly facilitates the operation of the lathe or the cleaning work of the lathe.

[0034] On the other hand, through the cooperation of the scraping assembly with the side collection basket 500 and the top collection basket 600, combined with the functions of the movable space 300 and the blanking space 400, the iron filings, coolant and other substances adhered and remaining on the top cover can be scraped off and finally fall into the top collection basket 600, ensuring the safety of the operator. Even if there are still residual substances on the edge of the top cover or on the scraping assembly, during the rising, falling or suspension process of the cover, these residual substances can only fall into the blanking space 400 and then into the top collection basket 600, further ensuring the safety of the operator.

[0035] Finally, by using the side collection basket 500 to collect a certain amount of iron filings, it not only reduces the subsequent iron filings cleaning work, but also avoids the iron filings and other substances adhered to the corresponding protective surface of the side cover 200 from slipping, thereby further ensuring the safety of the operator.

[0036] Further, as Figure 1 and Figure 2 shown, the bottoms of the side collection basket 500 and the top collection basket 600 are both in an arc-shaped groove. The side walls of the two side collection baskets 500 arranged facing each other are both inclined and the distance between them gradually increases from top to bottom. On the one hand, the arc-shaped groove arrangement increases the storage space. On the other hand, the inclined side walls of the side collection basket 500 can most avoid the adhesion and residue of iron filings and other substances on the outer side of the side walls, and at the same time can ensure that the iron filings adhered to the inside of the side walls can slide down along the side walls into the corresponding side collection basket 500.

[0037] Further, the side collecting basket 500 and the top collecting basket 600 are both detachably connected to the side cover 200 (not shown in the figure) for easy cleaning, maintenance, etc. It should be noted that a sealing design is required between the side collecting basket 500 and the top collecting basket 600 and the side wall of the corresponding side cover 200 to prevent iron filings and the like from falling onto the operator through the possible gaps in the non-sealed part. The detachable connection and the sealing design are both prior arts and will not be elaborated here.

[0038] As Figures 1-6 shown, according to another embodiment of the present invention, the top cover includes a first top plate 110 and a second top plate 120 connected to the first top plate 110, and the longitudinal cross-section of the space enclosed by the first top plate 110 and the second top plate 120 is in an inverted V shape; two baffles 130 are correspondingly connected to the bottoms of the first top plate 110 and the second top plate 120;

[0039] One scraping assembly is provided on each of the first top plate 110 and the second top plate 120, and each scraping assembly includes a scraping plate 710, a slide rail 720, a sliding part 730 and a traction part; the scraping plate 710 is slidably attached to the bottom surface of the first top plate 110 or the second top plate 120 and the activity space 300 is located on the sliding path of the scraping plate 710; the slide rail 720 is connected to the first top plate 110 or the second top plate 120 and is arranged along the length direction of the first top plate 110 or the second top plate 120; the sliding part 730 is connected to the scraping plate 710 and is slidably limited on the slide rail 720; the traction part is connected to the sliding part 730 and is used to drive the sliding part 730 to slide along the length direction of the slide rail 720.

[0040] In the embodiment of the present invention, specifically:

[0041] As Figure 1 and Figure 2 shown, the angle between the first top plate 110 or the second top plate 120 and the horizontal plane is preferably about 30°, and the inclination angle of each side cover 200 in the vertical direction is preferably within 30°; the activity space 300 should be as small as possible to ensure that the scraping plate 710 can pass through. Correspondingly, the thickness of the scraping plate 710 should be as small as possible to save space; the connection mode between the baffle 130 and the first top plate 110 or the second top plate 120 is preferably an integrally formed design, which is beautiful and convenient for cleaning; the number of slide rails 720 can be one or more, which is relatively flexible; the operation mode of the traction part can be linear pulling or rotation, etc., as long as it can conveniently drive the sliding part 730 to slide along the length direction of the slide rail 720.

[0042] Based on the above scheme, preferably, as Figures 3-5As shown, the number of slide rails 720 in each scraping assembly is two. The two slide rails 720 are parallel to each other and are both arranged along the length direction of the first top plate 110 or the second top plate 120. The sliding part 730 is provided with two sliding grooves, and the two sliding grooves are respectively and slidably limited on the corresponding slide rails 720. The two slide rails 720 can ensure that the sliding of the sliding part 730 is relatively stable, thereby ensuring the uniform scraping effect of the scraping plate 710.

[0043] Meanwhile, preferably, as Figures 1-6 shown, the traction part includes a lead screw 741 and a rocking wheel 742. The lead screw 741 is arranged parallel to the corresponding slide rail 720, and one end of the lead screw 741 is threadedly connected to the sliding part 730. Preferably, a through hole 731 ( Figure 5 ) that is threadedly matched with the lead screw 741 is opened at the central position of the sliding part 730, and one end of the lead screw 741 passes through the through hole 731 and extends to near the connection of the first top plate 110 and the second top plate 120 ( Figure 3 ). At this time, the lead screw 741 can not only drive the sliding part 730 to slide, but also play a limiting role on the sliding part 730. The rocking wheel 742 is connected to the other end of the lead screw 741. The rocking wheel 742 can be an L-shaped rotating handle or a turntable, etc., as long as it is convenient to drive the rotation of the lead screw 741. More preferably, in order to make the positions of the lead screw 741 and the rocking wheel 742 relatively stable for easy use, the traction part further includes a support body 743 ( Figure 3 and Figure 4 ), the support body 743 is arranged at the bottom end of the top surface of the first top plate 110 or the second top plate 120, and the lead screw 741 freely passes through the support body 743 and is connected to the rocking wheel 742.

[0044] Further preferably, as Figure 6 shown, the size of the scraping plate 710 along the width direction of the first top plate 110 or the second top plate 120 is smaller than the size of the opening of the corresponding top collecting basket 600 along the same direction. Specifically, for the convenience of connection between the scraping plate 710 and the sliding part 730, the length of the scraping plate 710 needs to be greater than the width of the first top plate 110 or the second top plate 120 ( Figure 6 ). Therefore, when the opening lengths (along the width direction of the corresponding side cover 200) of the side collecting basket 500 and the top collecting basket 600 are preferably both greater than the width of the corresponding side cover 200, it is further preferably that they are both greater than the length of the corresponding scraping plate 710.

[0045] Even more preferably, as Figures 1-5As shown, both ends of the slide rail 720 have cut-off portions 721. Preferably, the cut-off portions 721 are integrally formed with the slide rail 720. As long as it is ensured that the cut-off portions 721 are higher than the slide rail 720 by a sufficient height so that the sliding portion 730 is not easily slipped off. In addition, the dimension of the cut-off portion 721 along the length direction of the first top plate 110 or the second top plate 120 is preferably greater than the dimension of the support body 743 in the same direction to ensure the maximum displacement of the sliding portion 730.

[0046] As Figure 1 , Figure 2 and Figure 5 shown, according to another embodiment of the present invention, the lifting assembly includes a motor 810 and a lifting rope 820. The motor 810 is arranged above the cover body, and one end of the lifting rope 820 is wound around the rotating shaft of the motor 810 and the other end is connected to the top cover.

[0047] Specifically, the motor 810 can be fixed on the ceiling above the lathe or on a stable bracket; preferably, there are two lifting ropes 820. The two lifting ropes 820 are arranged in parallel and one end of each of them is preferably fixed on the cut-off portion 721 ( Figure 5 ). More specifically, two adjacent cut-off portions 721 at the connection of the first top plate 110 and the second top plate 120 are divided into a group, and one lifting rope 820 is commonly fixed on each group of two cut-off portions 721. The fixing method can be selected as the tying method after perforation, and then the fixing of the lifting rope 820 can be flexibly released according to needs; the other ends of the two lifting ropes 820 are both wound and fixed on the rotating shaft of the motor 810, and the parts of the two lifting ropes 820 between the motor 810 and the cover body have equal lengths; in addition, preferably, two annular grooves are arranged at intervals along the length direction of the rotating shaft of the motor 810, and the depth of each annular groove is large enough to wind the lifting rope 820 to the greatest extent while ensuring that the overlapping part of the wound lifting ropes 820 is always inside the groove. To cooperate with the annular grooves, the shape of the lifting rope 820 is preferably a sheet with a certain width and a very small thickness. More preferably, the sheet-like lifting rope 820 has no elasticity and has a rough surface.

[0048] Finally, preferably, the technical solution of this embodiment is a further optimization based on the foregoing embodiments.

[0049] When this embodiment is in use:

[0050] Installation and fixation of the motor 810: The motor 810 needs to be fixed at a suitable position above the lathe to ensure that the motor 810 can lower the cover body to the first position. When in the first position, after the protective surface inside the cover body completely shields the working area required for the lathe to machine workpieces of general length, there is still a certain amount of surplus space at both ends. And at this time, the part of the side cover 200 located between the bottom end of the baffle 130 and the top collection basket 600 is exactly in front of the above-mentioned working area of the lathe to provide better visualization operation conditions; at the same time, ensure that the motor 810 can also lift the cover body to the second position, and the second position is at a certain height above the lathe to avoid interference with the cutting or cleaning work of the lathe when the chip guard cover of the lathe is idle.

[0051] During use: First, ensure that the two scraping plates 710 are in contact with each other. Then, start the lathe and wait for the lathe to run stably. Start the motor 810 to release part of the winding of the upper end of the lifting rope 820 wound around the rotating shaft of the motor 810, so as to lower the cover body fixed at the lower end of the lifting rope 820 to the first position; then turn off the motor 810, and the lathe operator stands facing the outer wall of one of the side covers 200. When the lathe is cutting, part of the flying iron chips and coolant directly fall into or slide into the side collection basket 500 along the inner wall of the side cover 200, part fall on the lathe or the ground, and a small amount adheres to the protective surface of the chip guard cover of the lathe (including the inner wall of the side cover 200, the inner walls of the first top plate 110 and the second top plate 120, and the wall surface of the scraping plate 710), thus avoiding harm to the operator.

[0052] After use: After the lathe cutting is completed, rotate the two handwheels 742 respectively to make the scraping plates 710 slide downward along the inner walls of the first top plate 110 or the second top plate 120 to scrape off the iron chips and the like adhering and remaining on the inner walls. Stop when the handwheel 742 is resisted and cannot rotate further. When stopped, the scraping plates 710 are above the blanking space 400, and the scraped iron chips and the like fall into the lathe or the ground, the side collection basket 500, and the top collection basket 600 in sequence; as needed, the top collection basket 600 and the side collection box can be disassembled to clean the iron chips and other substances therein, and the iron chips and the like adhering and remaining on the wall surface of the cover body can also be further cleaned, and then the top collection basket 600 and the side collection box are installed. Then start the motor 810 to gradually wind the upper end of the lifting rope 820 around the rotating shaft of the motor 810 to lift the cover body to the second position; during the lifting or suspension of the cover body, a small amount of iron chips and the like adhering and remaining on the lower end of the inner wall of the first top plate 110 or the second top plate 120 or the scraping plate 710 can only fall into the top collection basket 600, and a small amount of iron chips and the like adhering and remaining on the wall surface of the side cover 200 can only fall into the side collection basket 500 or the top collection basket 600, thus avoiding harm to the operator.

[0053] In case of an emergency, the two scraping plates 710 can be quickly slid down, and then the motor 810 can be started to lift the cover body.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
