Description

Technical Field

[0001] The invention relates to the technical field of automobile mold frame production and processing, and in particular to a high-efficiency milling device based on the automobile mold frame and having a chip splash prevention structure. Background Art

[0002] The mold frame is an integral part of the mold. When manufacturing the automobile mold frame, in order to embed the mold core into the mold frame, it is necessary to use milling to mill out a groove of appropriate shape and size from the surface of the steel plate, and then place the mold core into the groove.

[0003] When the existing milling machine is working, the debris will splash everywhere, resulting in the accumulation of chips in various parts of the machine tool, including the dead corners, and the subsequent cleaning work is very cumbersome. In addition, when the milling machine is working, it is necessary to spray cutting fluid to cool and lubricate the tool, which will also cause the cutting fluid to splash everywhere, increasing the difficulty of cleaning. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention proposes a high-efficiency milling device with a chip splash-proof structure based on an automobile mold frame, which can shield the chips and cutting fluid splashing around when milling a workpiece.

[0005] In order to achieve the above-mentioned object, the present invention is implemented by the following technical scheme: an efficient milling device with a chip splash prevention structure based on an automobile mold frame, comprising a milling machine body and a blocking structure;

[0006] The anti-blocking mechanism includes a bracket and a baffle. Two brackets are symmetrically provided and are respectively located on both sides of the body of the milling machine. Each bracket is provided with a baffle, and the baffle is located on the workbench of the milling machine body. The two baffles can be connected to each other and enclose the outside of the workpiece.

[0007] When milling a workpiece, the brackets are set on both sides of the milling machine body and connected to each other through two baffles. After the workpiece is enclosed, the baffles can be used to intercept the debris and cutting fluid that splash outward during milling.

[0008] The beneficial effect of the above-mentioned efficient milling equipment with anti-chip splash structure based on the automobile mold frame is that the baffle can prevent chips and cutting fluid from splashing everywhere, keep the cleaning range of chips and cutting fluid within a smaller range, and reduce the difficulty of subsequent cleaning work.

[0009] Furthermore, the anti-blocking mechanism also includes a baffle plate 2, both ends of which are provided with through grooves, and the baffle plate 2 is slidably inserted into the through grooves. The baffle plate and the baffle plate 2 are both provided with electromagnets, and a debris groove is provided at the bottom. A plurality of T-shaped sliders are provided at the bottom of the baffle plate, and the T-shaped sliders are slidably connected to the T-shaped slide grooves of the workbench, and the baffle plate 2 fits against the surface of the workbench.

[0010] When in use, the baffle is slid relatively on the workbench, and then the second baffle is inserted from the through slots at both ends, so that the whole is enclosed on the outside of the workpiece. After starting milling, the electromagnet is turned on to absorb the debris splashed onto the baffle. After the milling is completed, the electromagnet is turned off to make the debris fall into the debris groove. The splashed cutting fluid can also flow downward from the baffle and the second baffle into the debris groove.

[0011] Furthermore, through holes communicating with the through slots are provided at the tops of both ends of the baffle, locking rods capable of abutting against two baffles are slidably inserted in the through holes, and the top of the baffle is connected to the locking rod via a spring.

[0012] According to different workpieces, the distance between the two baffles can be adjusted to be as close to the workpiece as possible to improve the splash-proof effect. After the second baffle passes through the through slot, the locking rod can be pressed against the second baffle by the spring, thereby keeping the baffle and the second baffle relatively fixed.

[0013] Furthermore, multiple layers of detachable filter screens are arranged in the debris trough, and the mesh openings of the filter screens gradually become smaller from top to bottom.

[0014] The multi-layer filter can collect the debris in layers according to their size for easy recycling, and the cutting fluid can flow through the mesh holes to separate the debris and cutting fluid.

[0015] Furthermore, a waste liquid tank is provided at the bottom of the debris tank, a drain port connected to the outside is provided at the bottom of the waste liquid tank, a switch valve is provided at the drain port, and the bottom of the waste liquid tank has an inclined surface, which is inclined downward toward the drain port.

[0016] After the cutting fluid flows down through the chip trough to the waste liquid trough, it can be discharged from the drain port through the inclined surface, so that the waste liquid can be easily collected and the convenience of cleaning is improved.

[0017] Furthermore, it also includes a cleaning mechanism, which includes a hanging frame, a motor, a lifting frame and a scraper, wherein the hanging frame is detachably arranged on the baffle, the motor is arranged on the hanging frame and connected to the lifting frame through a transmission, and the scraper is connected to the lifting frame and fits with the baffle and can be extended and retracted;

[0018] The transmission device includes a collar, major arc gear teeth and sector teeth. The collar is connected to the output shaft of the motor. The major arc gear teeth and sector teeth are circumferentially arranged on the collar. Racks of different sizes are arranged on both sides of the lifting frame. The two racks are respectively meshed with the major arc gear teeth and the sector teeth, and meshed alternately.

[0019] After each workpiece is milled, the anti-blocking mechanism can scrape the debris down through the cleaning mechanism to prevent excessive debris on the baffle from affecting the anti-blocking effect. After the suspension frame is set on the baffle, the motor is started to drive the ring to rotate. The rotation of the ring drives the arc-shaped gear teeth and the fan-shaped teeth to engage with the racks on both sides of the lifting frame in turn, thereby driving the lifting frame and the scraper bar to move up and down, scraping the debris on the baffle down into the debris groove, and the two racks are of different sizes, corresponding to the smaller gear teeth and the larger fan-shaped teeth respectively, so that the lifting frame can descend slowly when descending to avoid debris splashing too fast, and can rise quickly when rising.

[0020] Furthermore, a limiting sleeve is provided on the baffle, and a limiting column slidably connected to the limiting sleeve is provided on the lifting frame.

[0021] Through the cooperation of the limit column and the limit sleeve, the movement trajectory of the lifting frame can be limited and the stability during movement can be improved.

[0022] Furthermore, the suspension frame is provided with a hook and a fixer, the hook can be hung on the top of the baffle, the fixer includes a screw and a transmission gear, the baffle is provided with a threaded hole, the screw is rotatably connected to the threaded hole, the transmission gear is rotatably arranged on the suspension frame and threadedly connected to the screw, and the output shaft of the motor is provided with a driving gear meshing with the transmission gear.

[0023] Before using the anti-blocking mechanism, you can first hang the suspension frame on the baffle through the hook, and then turn on the motor to rotate forward. The active gear drives the transmission gear to rotate, so that the screw rotates into the threaded hole, completing the connection between the hook and the baffle, and improving stability. Then when using the cleaning mechanism, turn on the motor to reverse, and the active gear drives the transmission gear to screw the screw out of the threaded hole. At the same time, the motor drives the lifting frame to reciprocate through the transmission to slowly descend and quickly rise, so that the suspension frame can be removed from the baffle while cleaning the baffle.

[0035] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0036] See also Figures 1 to 6 The present invention provides an efficient milling device with a chip splash prevention structure based on an automobile mold frame, including a milling machine body 10 and a blocking structure. When the milling machine body 10 mills a workpiece, the blocking structure can block the splashing chips and cutting fluid, etc., so as to facilitate cleaning after the processing is completed.

[0037] Specifically, Figures 1 to 4As shown, the anti-blocking mechanism 20 includes a bracket 21 and a baffle 22. Two brackets 21 are symmetrically provided, respectively arranged on both sides of the body 11 of the milling machine body 10. The baffle 22 is arranged on the bracket 21 and is located on the workbench 12 of the milling machine body 10. The two baffles 22 can be enclosed on the outside of the milling workpiece to block the flying debris and cutting fluid.

[0038] Specifically, the anti-blocking mechanism 20 also includes a baffle plate 23, both ends of which are provided with through grooves, and the baffle plate 23 is slidably plugged with the through grooves, so that the two baffle plates 22 can be connected to enclose a rectangular space. The inside of the baffle plate 22 and the baffle plate 23 are both provided with electromagnets, and the side of the bottom facing inward is provided with a debris groove 24. After the electromagnet is energized, it can absorb the debris splashed on the board surface to prevent it from rebounding to the workpiece processing area. After the processing is completed, the electromagnet is turned off, and the debris can fall into the debris groove 24. At the same time, the liquid splashed on the board surface during the processing process can also flow down into the debris groove 24. In this embodiment, a plurality of T-shaped sliders 25 are provided at the bottom of the baffle plate 22, and the T-shaped sliders 25 are slidably connected to the T-shaped slide grooves of the workbench 12, and the baffle plate 23 is also attached to the workbench 12 and slidably connected, so as to ensure the effect of enclosure and keep the subsequent cleaning range within the enclosed space.

[0039] Through holes communicating with the top of the through groove are provided at the top of both ends of the baffle 22, and limiting holes are provided on both sides of the through holes. A locking rod 221 that abuts against the top of the baffle 23 is slidably inserted in the through hole, and a limiting rod 223 is slidably inserted in the limiting hole. The top of the locking rod 221 is connected to the limiting rod 223 through a connecting piece 224, and the outer sleeve of the limiting rod 223 is provided with a spring 222 that abuts against the baffle 22. During operation, the connecting piece 224 presses the locking rod 221 downward through the action of the spring 222, pressing the baffle 23 so that it cannot move. When taking out the baffle 22, the locking rod 221 can be pulled upward.

[0040] Multiple layers of filter screens 241 are detachably provided from top to bottom in the chip trough 24, and a waste liquid trough 26 is provided at the bottom. The detachable filter screen 241 is convenient for removing and pouring out the debris, and the meshes of the multiple filter screens 241 gradually become smaller from top to bottom, so that the debris can be collected in layers according to size, which is convenient for subsequent recycling. A drain port 261 connected to the outside is provided at the bottom of the waste liquid trough 26. The bottom of the waste liquid trough 26 has an inclined surface, which gradually tilts downward toward the drain port 261. A switch valve is provided at the drain port 261. After the cutting fluid flows through the chip trough 24 to the waste liquid trough 26 and accumulates, the drain port 261 can be opened by the switch valve to discharge the waste liquid, which is convenient for the operator to clean the accumulated liquid.

[0041] Specifically, Figure 5 and Figure 6As shown, the cleaning mechanism 30 is also included, including a hanging frame 31, a motor 32, a lifting mechanism and a scraper 34. The hanging frame 31 is detachably arranged on the baffle 22. The motor 32 is arranged on the hanging frame 31 and connected to the lifting frame 33 through a transmission, and can drive the lifting frame 33 to move up and down. The scraper 34 is arranged at the bottom of the lifting frame 33 and fits with the baffle 22. The scraper 34 can be extended and retracted. By moving the lifting frame 33 up and down, the scraper 34 can scrape off the debris on the baffle 22 to prevent some debris mixed with cutting fluid from adhering to the plate surface. The transmission device includes a collar 351, arc-shaped gear teeth 352 and sector-shaped teeth 353. The collar 351 is connected to the output shaft of the motor 32. The arc-shaped gear teeth 352 and the sector-shaped teeth 353 are circumferentially arranged on the collar 351. Racks 331 of different sizes are arranged on both sides of the lifting frame 33. The arc-shaped gear teeth 352 and the sector-shaped teeth 353 can respectively mesh with the two racks 331 and mesh alternately.

[0042] When the motor 32 drives the collar 351 to rotate, the arc-shaped gear 352 first meshes with one of the racks 331, driving the lifting frame 33 to move downward. The arc-shaped gear 352 and the rack 331 have more teeth and smaller teeth, thus driving the lifting frame 33 and the scraper bar 34 to move slowly when scraping debris downward. Then the sector-shaped gear 353 meshes with the other rack 331, driving the lifting frame 33 to move upward. The sector-shaped gear 353 and the other rack 331 have less teeth and larger teeth, thus driving the lifting frame 33 and the scraper bar 34 to rise quickly. In addition, a limiting sleeve 224 is provided on the suspension frame 31, and a limiting column 332 slidably connected to the limiting sleeve 224 is provided on the lifting frame 33 to limit the lifting frame 33 to move only in the vertical direction.

[0043] Furthermore, the suspension frame 31 is provided with a hook 311 and a fixer, the hook 311 is used to be suspended on the top of the baffle 22, the fixer includes a screw rod 312 and a transmission gear 313, the baffle 22 is provided with a threaded hole, the screw rod 312 can be threadedly connected with the threaded hole, the transmission gear 313 is rotatably arranged on the suspension frame 31, and is sleeved on the screw rod 312 and threadedly connected with it, and the output shaft of the motor 32 is provided with a driving gear 314 meshing with the transmission gear 313. Before milling the workpiece, the suspension frame 31 can be hung on the baffle 22, and after the motor 32 is started to rotate, the driving gear 314 drives the transmission gear 313 to rotate, thereby driving the screw rod 312 to rotate and screw into the threaded hole, completing the fixing of the suspension frame 31, and at this time, the motor 32 drives the lifting frame 33 to perform rapid descent and slow ascent movements. After the workpiece is processed, the motor 32 can be started to reverse, driving the lifting frame 33 to slowly descend and quickly rise, cleaning the baffle 22. At the same time, the driving gear 314 drives the screw 312 to rotate outward through the transmission gear 313, and the suspension frame 31 is removed from the baffle 22 while cleaning the baffle 22. After the cleaning is completed, the suspension frame 31 can be directly removed. In this embodiment, the suspension frame 31 and the lifting frame 33 are respectively located on both sides of the baffle 22. The motor 32 is a double-axis motor, one end of which passes through the baffle 22 and is connected to the collar 351 to drive the lifting frame 33, and the other end is provided with a driving gear 314 to drive the screw 312. In addition, the cleaning mechanism 30 can be hung on the baffle 22 or on the baffle 23, and the length of the scraper strip 34 can be adjusted and extended.

[0044] The working principle of the above-mentioned efficient milling equipment with anti-chip splashing structure based on the automobile mold frame is: the bracket 21 is moved to both sides of the body 11 of the milling machine body 10, and is fixedly connected to the baffle 22 through the baffle 23, and is enclosed on the outside of the workpiece. The cleaning mechanism 30 is first installed on each baffle 22. After the fixation is completed, the workpiece can be milled. The baffle 22 and the baffle 23 turn on the electromagnet to block the splashing chips and cutting fluid, and can absorb the chips. After the milling is completed, the electromagnet is turned off, and the cleaning mechanism 30 is started to scrape the chips and liquid on the plate surface into the chip tank 24 and the waste liquid tank 26, and then the cleaning mechanism 30 can be removed.

[0045] The use of the above-mentioned efficient milling equipment with a chip splash prevention structure based on the automobile mold frame can shield the splashing chips and cutting fluid, and only needs to be cleaned within a smaller range, and can collect the chips and cutting fluid, making subsequent cleaning more convenient.
