[0004] The purpose of this invention is to provide a polishing device with protective function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device with protective function, comprising a base plate, vibration isolators fixedly installed at the four right angles of the bottom of the base plate, and columns fixedly installed at the four right angles of the top of the base plate. A closed cabinet is fixedly installed on the top of the four columns, and a top cover is hinged to the closed cabinet. Air intake fans are fixedly installed on the left and right sides of the outer wall of the top cover by bolts. A grinding assembly, a locking assembly, and a control cabinet are arranged sequentially from left to right on the front side of the closed cabinet. A filter assembly is provided in the middle of the top of the base plate, and a transverse partition is fixedly installed in the middle of the four columns.

[0006] The filter assembly includes two conveying pipes, the outer walls of which are fixedly installed on the front and rear sides of the enclosed cabinet respectively. A dust suction port is provided at one end of the conveying pipe inside the enclosed cabinet, and a protective net is slidably inserted into the outer wall of the dust suction port. The other ends of the two conveying pipes are connected to and communicate with the filter box below through an explosion-proof fan. A dust collection box and multiple filter boxes are movably inserted into the front side of the outer wall of the filter box from left to right. A silencer exhaust pipe is provided on the top right side of the filter box.

[0007] The beneficial effects of this utility model are as follows: the device can move the sliding base to a suitable position by turning the rotating handle, close the top cover, pull the pin to push the micro switch, the controller starts the second motor to drive the brush cylinder to grind, and the explosion-proof fan sucks the dust in the enclosed cabinet into the filter box for filtration and discharge, which reduces the risk of personal injury and prevents damage to the grinding equipment.

[0008] To enable the brush barrel to grind and deburr gears of different diameters, thus expanding the range of grinding applications:

[0009] The grinding assembly is further configured as follows: the grinding assembly includes a second motor, which is fixedly mounted on the front sliding plate of the outer wall of the enclosed cabinet by bolts. A sliding base and a brush cylinder are sequentially fitted onto the outer wall of the output end of the second motor from front to back. The brush cylinder is located in the middle of the sliding base. Both the front and rear sides of the bottom of the sliding base are threaded with lead screws through trapezoidal nuts. The left ends of the two lead screws are provided with first gears, and the two first gears are connected by a toothed belt drive. Fixed plates are movably fitted onto the left and right sides of the two lead screws. The top of the fixed plates is fixedly installed on the left and right sides of the bottom of the enclosed cabinet. A rotating handle is provided at the right end of the rear lead screw. The sliding base is located in the middle of the two fixed plates.

[0010] By adopting the above technical solution, turning the rotary handle drives one lead screw to rotate, which in turn drives another lead screw to rotate through the transmission connection between the first gear and the toothed belt. The rotation of the two lead screws drives the second motor and the brush cylinder on the sliding base to move linearly. The second motor drives the brush cylinder to rotate to grind and remove burrs from the gear to be ground, thus expanding the grinding adaptability range.

[0011] To ensure stable closure of the top cover and the enclosed cabinet and improve operational safety:

[0012] The locking assembly is further configured as follows: the locking assembly includes three fixing blocks, the rear sides of the three fixing blocks are fixedly installed on the front side of the outer wall of the enclosed cabinet, the middle hole of the three side-by-side fixing blocks is movably inserted with a pin, and the right end of the rightmost fixing block is provided with a micro switch, the outer wall of the pin is provided with a protruding ring, and the left side of the protruding ring is connected to the right side of the leftmost fixing block through a spring, the pin is provided with an insert block above the pin, and the insert block is movably sleeved with a reinforcing block through the fixing shafts on the left and right sides, and the rear side of the reinforcing block is fixedly installed on the top cover.

[0013] By adopting the above technical solution, the top cover is closed, and the insert block is pulled down around the reinforcing block sleeve. The insert block aligns with the holes of the three fixing blocks. The pin that is pulled is released, and the pin is reset by the spring, so that the end is fully inserted into the rightmost fixing block until it hits the micro switch, thus realizing the stable closure of the top cover and the enclosed cabinet. The controller integrates a PLC controller, display panel and emergency stop button, etc. The two are connected through internal circuits. The controller controls the start and stop of each power unit, improving operational safety.

[0014] To ensure that the gears inside the enclosed cabinet to be ground can be easily replaced with gears of different diameters, thus improving adaptability:

[0015] The following configuration is further provided: a first motor is fixedly installed at the bottom of the enclosed cabinet by bolts, the output end of the first motor passes through the bottom of the enclosed cabinet and extends into the interior of the enclosed cabinet, the output end of the first motor is movably sleeved with a gear to be ground, and the output end port of the first motor is threadedly connected with a nut.

[0016] By adopting the above technical solution, a suitable gear is selected from gears of different diameters to be ground and fitted into the output end of the first motor. Then, the nut is aligned with the thread of the output end port and tightened until it is tightened to keep the gear to be ground stable before starting the first motor to drive the gear to be ground to rotate, thereby improving the adaptability and efficiency of the grinding range.

[0017] To minimize the high-speed metal shavings generated during grinding, reduce the risks associated with grinding, and improve safety:

[0018] Further configuration: the enclosed cabinet is made of thickened steel plate with a thickness greater than two millimeters, the top cover is made of high-strength polycarbonate, and the top of the outer wall of the enclosed cabinet has a groove with the same size as the outer wall structure of the top cover.

[0019] By adopting the above technical solution, the metal shavings splashed by the brush during the grinding of gears are shielded by the enclosed cabinet to avoid splashing. The top cover made of high-strength polycarbonate material is not only impact-resistant but also easy to observe. The top cover and the enclosed cabinet are kept sealed internally by protrusions and grooves, which improves production safety.

[0034] The computer software involved in the hardware carriers such as the first motor in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0035] Therefore, the "first motor," "second motor," and "explosion-proof fan" mentioned in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the grinding device with protective function of this application, so as to solve the corresponding technical problems to be solved by this application.

[0036] The working process of this protective grinding device is as follows:

[0037] First, the worker selects a suitable gear from among the gears to be ground, of different diameters, and inserts it into the output end of the first motor. Then, the nut is aligned with the threaded end of the output motor and tightened until it is securely fastened. After ensuring the gear is stable, the worker rotates the handle, causing one lead screw 604 to rotate. This, through the transmission connection between the first gear 605 and the toothed belt 606, drives the other lead screw 604 to rotate. The rotation of both lead screws 604 causes the sliding base 602 to move linearly, thereby causing the second motor 601 and the brush cylinder 603 to move linearly along the groove on the enclosed cabinet 4. The second motor 601 is fixedly mounted on the sliding plate, which is movably inserted into a groove on the front side of the outer wall of the enclosed cabinet 4. The process continues until the bristles of the brush cylinder 603 can grind the burrs inside the gear teeth. Then, the top cover is pressed down by the insert block 704, causing the lower edge of the top cover to protrude and completely fit into the groove on the top of the enclosed cabinet 4. The insert block 704 is then moved. Insert block 704 rotates and falls around the axis of reinforcing block 705. Insert block 704 aligns with the holes of the three parallel fixing blocks 701. Releasing the holding pin 702 causes the pin 702 to spring back, fully inserting its end into the rightmost fixing block 701 until the end touches the microswitch, thus achieving stable closure of the top cover and the enclosed cabinet 4. The control cabinet 8 integrates a PLC controller, display panel, and emergency stop button, all connected by internal wiring. Upon detecting that pin 702 is closed, the control cabinet 8 starts the first motor to rotate the gear to be ground. The air intake fan 5 begins to draw air into the enclosed cabinet 4. Simultaneously, the second motor 601 drives the brush cylinder 603 to begin grinding and deburring the gear. The explosion-proof fan 903, through two suction ports 902, diverts and sucks in grinding debris. Explosion-proof fan 903 models include, but are not limited to, HDF. The IECEx explosion-proof type features a protective mesh inserted into the suction port 902, which minimizes sparks. Waste is then guided into the conveying pipe 901, lined with conductive carbon fiber, and then enters the filter box 904. Heavier waste falls into the dust collection box 905, while lighter dust gas flows to the right through multiple filter boxes 906 containing PTFE microporous membrane activated carbon and a conductive layer to filter impurities. The gas is then discharged from the silencer exhaust pipe 907, improving the quality of the working environment for workers and reducing occupational diseases.
