Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of protective covers, in particular to a precision sheet metal protective cover. BACKGROUND

[0002] Sheet metal protective covers are core components for protecting mechanical rotating parts in industrial equipment, used to block chips and isolate dangerous components to prevent human contact and mechanical injury.

[0003] Currently, existing sheet metal protective covers need to go through a series of assembly steps in the use process: first, they are welded into a complete whole structure, then transported to the designated installation site, then the installation of the protective cover is completed at the location; after that, the relevant equipment is placed inside the protective cover, and finally the door panel is installed. This design gives the protective cover strong overall structure, however, the volume of the welded protective cover increases significantly, not only occupying a lot of space during transportation, but also being easily collided during transportation, which may cause deformation and damage of the protective cover.

[0004] In addition, in terms of use function, the protective cover mainly realizes the function of personnel entering and exiting the internal space through the door panel. However, when the equipment inside the protective cover is in operation, the door panel can still be freely opened, which means that personnel can enter at will, which undoubtedly lays a serious safety hazard.

[0005] Furthermore, when the equipment inside the protective cover is processing, a certain amount of dust will be generated. Although part of the dust will be adsorbed by the cooling liquid when the cooling liquid is used for cooling treatment, part of the dust will still be emitted and deposited on the surface of the equipment. Over time, the accumulation of these dusts will interfere with the normal operation of the equipment, and even cause equipment failure, so a device is needed to solve the above problems. SUMMARY

[0006] The technical problem to be solved by the present application is to overcome the defects existing in the prior art, and the present application provides a precision sheet metal protective cover.

[0007] To solve the above technical problems, the technical scheme adopted by the present application is: A precision sheet metal protective cover includes: a support portion, on the top of which a protective portion is mounted; the support portion includes a first base plate and a second base plate, two of which are provided, and the first base plate and the second base plate are fixed together by a splicing assembly; the protective portion includes a sleeve block installed on the top of the first base plate and the second base plate, and a support column installed inside the sleeve block; a side plate is slidably mounted on the support column through a groove, the top of the groove penetrating the top of the support column; a top plate is mounted on the top of the support column; the first base plate and the second base plate are spliced ​​together in a grid pattern, then fixed together by the splicing assembly, and the support column is fixed inside the sleeve block; the side plate is moved downwards along the groove from the top of the support column until the side plate is tightly against the top of the first base plate and the second base plate; finally, the top plate is installed on the top of the support column.

[0008] Preferably, a rubber pad is installed on the contact surface between the side plate and the slide groove, and the rubber pad is installed on either side of the contact surface between the side plate and the slide groove.

[0009] Preferably, the splicing assembly includes a first splicing plate installed at the splicing point of the first base plate and the second base plate; it also includes a second splicing plate installed at the splicing point of the first base plate and the second base plate, the second splicing plate being L-shaped and installed at the corner position of the splicing point of the first base plate and the second base plate.

[0010] Preferably, a door panel is rotatably mounted on the side panel; a transparent observation panel is mounted on the door panel for observing the inside of the side panel; and a limiting component for restricting the position of the door panel is mounted on the side panel.

[0011] Preferably, the limiting component includes a hollow block mounted on the side plate; a control box mounted on the hollow block; a baffle mounted inside the hollow block; a motor mounted at the top inside the hollow block; a screw mounted at the bottom output end of the motor, the bottom of the screw being rotatably mounted inside the bottom of the hollow block; a connecting block mounted on the outside of the screw via a threaded connection, the connecting block being mounted on the baffle; the motor drives the screw to rotate, causing the connecting block to move axially along the screw, synchronously driving the baffle to move to the side of the door panel, thus limiting the door panel; the control box is wirelessly connected to the control system of the operating equipment inside the protective cover; when the equipment is in the start-up state, the door panel is closed by the baffle, forming a locked state.

[0012] Preferably, at least two baffles are provided, symmetrically installed on both sides of the door panel, and the bottom of the baffles can move through the bottom of the hollow block, so that the baffles can move up and down along the hollow block.

[0013] Preferably, a dust removal mechanism for removing dust from the inside of the protective cover is installed on the top of the top plate. The dust removal mechanism includes a fan installed on the top of the top plate; a first pipe extending into the inside of the top plate through the fan input end; a suction assembly for sucking up dust installed at the bottom of the first pipe; and an exhaust pipe installed at the air output end of the fan.

[0014] Preferably, the suction assembly includes a second pipe installed at the bottom of the first pipe, the second pipe being a multi-head pipe with at least two branch heads at the bottom; a horn pipe is installed at the bottom of the second pipe; a serpentine pipe is installed at the bottom of the horn pipe; the fan is activated to extract air from inside the first pipe, creating a negative pressure inside the first pipe, thereby drawing air out of the protective cover through the second pipe to achieve a dust removal effect.

[0015] Preferably, a recovery mechanism for recovering coolant is installed on the top of the first base plate and the second base plate. The recovery mechanism includes a recovery box installed on the top of the first base plate and the second base plate.

[0017] Compared with the prior art, the beneficial effects of the present invention include: 1. When the protective cover is not installed, the support column, the first base plate, the second base plate and the side plate are separate structures. This greatly reduces the size of the device during transportation and prevents the protective cover from being deformed by collisions due to its large size during movement.

[0018] 2. Bend the serpentine tube so that the opening at the bottom of the serpentine tube extends to the dust production point of the equipment, which facilitates fixed-point dust removal. When the equipment is in operation, the fan starts to create negative pressure inside the first pipe, thereby sucking out the dust inside the protective cover and preventing dust accumulation.

[0019] 3. When the equipment is running, the control system transmits signals to the control box. The control box then starts the motor, which drives the screw to rotate. The connecting block, welded to the baffle, cannot rotate with the screw, causing the screw and connecting block to rotate relative to each other. This causes the connecting block to move axially along the screw, synchronously moving the baffle to the side of the door panel, limiting its movement and locking the door. When the equipment stops, the motor drives the screw to move in the opposite direction, resetting the baffle and allowing the door to open again, preventing personnel from entering the protective cover while the equipment is running.

[0021] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0022] According to one embodiment of the present invention, Figures 1-6 As shown.

[0023] A precision sheet metal protective cover includes: a support part 1, and a protective part 2 mounted on top of the support part 1. The support part 1 includes a first base plate 11 and a second base plate 12, with two such plates, the first base plate 11 and the second base plate 12 being fixed together by a splicing assembly. The protective part 2 includes a sleeve block 21 welded and fixed to the top of the first base plate 11 and the second base plate 12. A support column 22 is slidably mounted inside the sleeve block 21 and fixed by bolts after being installed inside the sleeve block 21. A side plate 23 is slidably mounted on the support column 22 through a groove 26, wherein the top of the groove 26 penetrates the top of the support column 22. A rubber pad is bonded and fixed to the contact surface between the side plate 23 and the groove 26, and the rubber pad is bonded and fixed to either side of the contact surface between the side plate 23 and the groove 26. A top plate 3 is bolted to the top of the support column 22. The first base plate 11 and the second base plate 12 are spliced ​​together in a grid pattern, and then fixed by splicing components. The support column 22 is then fixed inside the sleeve block 21. The side plate 23 is moved down from the top of the support column 22 along the slide groove 26 until the side plate 23 is tightly attached to the top of the first base plate 11 and the second base plate 12. Finally, the top plate 3 is fixed to the top of the support column 22 with bolts.

[0024] Specifically, the splicing assembly includes a first splicing plate 13 fixed to the splicing point of the first base plate 11 and the second base plate 12 by bolts; it also includes a second splicing plate 14 fixed to the splicing point of the first base plate 11 and the second base plate 12 by bolts, wherein the second splicing plate 14 is L-shaped and installed at the corner position of the splicing point of the first base plate 11 and the second base plate 12; after the first base plate 11 and the second base plate 12 are spliced, the first splicing plate 13 and the second splicing plate 14 are fixed together with bolts to ensure the stability of the spliced ​​assembly.

[0025] In this embodiment, a door panel 24 is rotatably mounted on the side panel 23 via a hinge; a transparent observation plate 241 is inlaid and fixed on the door panel 24, the transparent observation plate 241 is used to observe the inside of the side panel 23, wherein the transparent observation plate 241 is a transparent acrylic plate; a limiting component 25 for limiting the position of the door panel 24 is installed on the side panel 23.

[0026] Specifically, the limiting component 25 includes a hollow block 251 embedded and fixed on the side plate 23; a control box 252 is bolted onto the hollow block 251; a baffle 253 is installed inside the hollow block 251, at least two baffles 253 are provided, symmetrically installed on both sides of the door panel 24, the bottom of the baffle 253 moves through the bottom of the hollow block 251, allowing the baffle 253 to move up and down along the hollow block 251; a motor 254 is mounted on the top inside the hollow block 251 via a mounting bracket and bolts; a screw 255 is fixed to the bottom output end of the motor 254 via a coupling, wherein the bottom of the screw 255 is rotatably mounted on the bottom inside the hollow block 251 via a bearing; A connecting block 256 is threadedly installed on the outside of the screw 255. The connecting block 256 is welded and fixed to the baffle 253. The motor 254 drives the screw 255 to rotate. The connecting block 256 is welded to the baffle 253 and cannot rotate with the screw 255, so the screw 255 and the connecting block 256 rotate relative to each other. This causes the connecting block 256 to move axially along the screw 255, which in turn drives the baffle 253 to move to the side of the door panel 24, thus limiting the door panel 24. The control box 252 is wirelessly connected to the control system of the operating equipment inside the protective cover. When the equipment is in the start-up state, the door panel 24 is closed by the baffle 253, forming a locked state.

[0027] In this embodiment, a dust removal mechanism 4 for removing dust inside the protective cover is installed on the top of the top plate 3. The dust removal mechanism 4 includes a fan 46 that is bolted to the top of the top plate 3; the fan 46 is inserted into the top plate 3 through a first pipe 42 at its input end; a suction component for sucking up dust is installed at the bottom of the first pipe 42; and an exhaust pipe 41 is installed at the air output end of the fan 46.

[0028] Specifically, the suction assembly includes a second pipe 43 screwed onto the bottom of the first pipe 42. The second pipe 43 is a multi-head pipe, with at least two branch heads at the bottom. A horn pipe 44 is screwed onto the bottom of the second pipe 43. A serpentine pipe 45 is welded and fixed to the bottom of the horn pipe 44. When the fan 46 is started, it draws out the air inside the first pipe 42, creating a negative pressure inside the first pipe 42. This negative pressure draws out the air inside the protective cover through the second pipe 43, achieving a dust removal effect. The serpentine pipe 45 can be bent, and the position of the suction inlet at the bottom of the serpentine pipe 45 can be adjusted to the dust generation point, thus achieving a targeted dust removal effect.

[0029] In this embodiment, a recovery mechanism 5 for recovering coolant is installed on the top of the first base plate 11 and the second base plate 12. The recovery mechanism 5 includes a recovery box 51 disposed on the top of the first base plate 11 and the second base plate 12. The recovery box 51 is used to recover coolant that splashes onto the side plate 23 and then flows down. The recovery boxes 51 are attached to each other. A limiting unit for limiting the position of the recovery box 51 is installed on the first base plate 11 and the second base plate 12.

[0030] Specifically, the limiting unit includes a limiting groove 53 formed on the second base plate 12; a limiting rod 52 is slidably installed inside the limiting groove 53; after the recycling box 51 is placed on top of the first base plate 11 and the second base plate 12, the limiting rod 52 is inserted into the limiting groove 53 to limit the recycling box 51 in conjunction with the side plate 23.

[0031] Working principle: In use, the first base plate 11 and the second base plate 12 are spliced ​​together in a grid pattern, with the first base plate 11 symmetrically placed on both sides of the second base plate 12, and the second base plate 12 symmetrically placed on both sides of the first base plate 11. After the splicing is completed, the first splicing plate 13 is fixed to the outside of the contact position between the first base plate 11 and the second base plate 12 with bolts, and the two sides of the first splicing plate 13 are respectively tightly attached to the outside of the first base plate 11 and the second base plate 12. Similarly, the second splicing plate 14 is fixed to the inner side of the contact between the first base plate 11 and the second base plate 12 with bolts, and the two sides of the second splicing plate 14 are also tightly attached to the first base plate 11 and the second base plate 12. After fixing, the first base plate 11 and the second base plate 12 form a grid-shaped fixing structure. Next, insert the support column 22 into the sleeve block 21 and fix it with bolts. Insert the side plate 23 into the opening of the sliding groove 26 at the top of the support column 22, so that the side plate 23 and the support column 22 form a protective enclosure structure. Then, fix the top plate 3 to the top of the support column 22 with bolts. Fix the fan 46 to the top of the top plate 3 with bolts and fix it to the air input end of the fan 46 through the first pipe 42. The other side of the first pipe 42 goes into the bottom of the top plate 3. Then, install the door plate 24 in the door groove pre-opened in the side plate 23 with hinges. At this time, the protective cover is installed. When the protective cover is not installed, the support column 22, the first base plate 11, the second base plate 12 and the side plate 23 are separate structures. This greatly reduces the size of the device during transportation and prevents the protective cover from being deformed by collision during the movement due to its large size. After assembly, the equipment enters the protective cover through the door panel 24. The processing equipment is located inside the protective cover. The recycling box 51 is placed on the first base plate 11 and the second base plate 12. The limiting rod 52 is inserted into the limiting groove 53 to limit and fix the position of the recycling box 51. Then, the serpentine tube 45 is bent so that the bottom opening of the serpentine tube 45 extends to the dust production point of the equipment, which facilitates fixed-point dust removal. When the equipment is processing, the fan 46 is started to create a negative pressure inside the first pipe 42, thereby sucking out the dust inside the protective cover and preventing dust accumulation. When the equipment is processing, the coolant splashes onto the inner wall of the side plate 23. Under the action of gravity, the coolant flows downward and finally flows into the recovery box 51 to be collected. It can be processed periodically. When the equipment is running, the control system transmits signals to the control box 252. The control box 252 then starts the motor 254, which drives the screw 255 to rotate. The connecting block 256, welded to the baffle 253, cannot rotate with the screw 255, causing the screw 255 and connecting block 256 to rotate relative to each other. This causes the connecting block 256 to move axially along the screw 255, simultaneously moving the baffle 253 to the side of the door panel 24, limiting the door panel 24 and locking it in place. When the equipment stops, the motor 254 drives the screw 255 to move in the opposite direction, thereby resetting the baffle 253. This allows the door panel 24 to return to an openable state, preventing personnel from entering the protective cover while the equipment is running.

[0032] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
