Description

Technical Field

[0001] The invention relates to the technical field of rust removal of planetary reducers, in particular to a rust removal device for machining a two-stage planetary reducer for mining. Background Art

[0002] Planetary reducer is a widely used industrial product that can reduce the speed of the motor while increasing the output torque. Planetary reducer can be used as a supporting component in lifting, excavation, transportation, construction and other industries. Planetary reducer consists of gears, output planetary carrier, output internal gear ring, input shaft, etc. During the production and processing of planetary reducer, the gears are usually derusted through a rust removal device.

[0003] Publication No. CN214869576U discloses a rust removal device for planetary reducer processing. By providing a rust removal end head, the sandpaper on the rust removal end head can be quickly removed from the end head shell by adjusting the pressure plate on the adjustment plate, thereby facilitating the replacement of the sandpaper. In addition, a vibration motor is provided on the end head shell. During the high-speed rotation of the end head shell, the vibration motor can drive the end head shell to vibrate, thereby shaking off the cleaned residual rust on the reducer, avoiding the situation where the residual rust covers the surface of the reducer and causes incomplete rust removal. However, this patent still has the following problems in actual use:

[0004] Although the rust removal device for planetary reducer processing can be quickly removed from the end shell by adjusting the pressure plate on the adjustment plate, thereby facilitating the replacement of the sandpaper, the planetary reducer accessories cannot be fully soaked when the rust is removed from the planetary reducer, so that the rust remover and the accessories can fully react, thereby affecting the rust removal effect. At the same time, in the prior art, after the rust remover is used for rust removal, the stubborn rust stains on the surface are polished and polished, and the rust and oxides on the surface of the workpiece react chemically to generate soluble salts. If they are not fully cleaned and neutralized, these salts may remain on the surface of the workpiece, affecting the subsequent polishing effect. If polishing is performed directly, the unevenness of the surface may be aggravated, affecting the final smoothness, thereby causing damage to the gear surface and affecting the service life of the gear.

[0005] Therefore, a rust removal device for processing a mining two-stage planetary reducer is proposed to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a rust removal device for processing a two-stage planetary reducer for mining, so as to solve the problem proposed in the above-mentioned background technology that the accessories of the planetary reducer cannot be fully soaked when rust removal is performed on the planetary reducer, so that the rust remover and the accessories can fully react, thereby affecting the rust removal effect. At the same time, in the prior art, after the rust remover is used for rust removal, the stubborn rust stains on the surface are polished and ground, and the rust and oxides on the surface of the workpiece react chemically to generate soluble salts. If sufficient cleaning and neutralization treatment are not performed, these salts may remain on the surface of the workpiece, affecting the subsequent polishing effect. If polishing is performed directly, the unevenness of the surface may be aggravated, affecting the final smoothness, thereby causing damage to the gear surface and affecting the service life of the gear.

The specific contents are as follows:

[0022] 1. By setting up a grinding and rust removal mechanism, not only can the first electric telescopic rod be used to drive the first fixed plate to move up and down, but also the preliminary adjustment of the height of the grinding equipment and the cleaning roller brush can be achieved, and at the same time, the first rotating motor is started to drive the first rotating worm to rotate.

By rotating the first limit bracket driven by the rotating motor, the direction of the cleaning scraper and the grinding device can be changed to adapt to tooth grooves of different angles. The rust stains on the gear surface can be preliminarily cleaned by the cleaning roller brush.

[0023] 2. By setting up a pretreatment mechanism, the rust stains on the gear surface can be preliminarily cleaned by using the rust remover in the rust removal pool inside the pretreatment box, and the clean water in the cleaning pool can be used to fully clean the gear surface to remove the rust stains after the gear surface treatment and the reactants produced by the reaction between the rust stains and the rust remover, so as to avoid the adhesion of certain reactants on the gear surface, thereby having a certain impact on the rust polishing.

Start the second rotating motor 216 to drive the second rotating worm 217 to rotate, and utilize the characteristics of the meshing connection between the second rotating worm 217 and the second rotating worm wheel 218 to make the second rotating worm wheel 218 drive the cleaning cover 219 and the threaded mounting base 220 to rotate, which can achieve full reaction and cleaning of the gear, improve the effect of gear pretreatment, and at the same time get rid of excess moisture. The bevel gear transmission assembly 222 and the second adjusting threaded rod 223 are driven to rotate by adjusting the knob 221, so that the second adjusting threaded sleeve 224 drives the placement column 225 to move, and the position of the placement column 225 can be adjusted. The gear without the gear shaft is placed on the outside of the placement column 225, and the gear with the gear shaft is placed on the threaded mounting base 220, so as to facilitate sufficient rust removal, soaking and water washing of the gear.

[0042] Secondly, the first electric telescopic rod 104 is used to drive the first fixed plate 105 to move up and down, so as to achieve preliminary adjustment of the height of the grinding device 133 and the cleaning roller brush 136. At the same time, the first rotating motor 107 is started to drive the first rotating worm 108 to rotate. By utilizing the characteristics of the meshing connection between the first rotating worm 108 and the first rotating worm wheel 109, the rotation of the adjusting disk 110 can be achieved, thereby changing the position of the grinding device 133 and the cleaning roller brush 136, which is convenient for grinding and rust removal of gear tooth grooves in different directions. By starting the adjusting motor 111 to drive the first adjusting threaded rod 112 to rotate, the first adjusting threaded sleeve 113 drives the second electric telescopic rod 114, the first fixed support 115 and the second fixed support 134 to move horizontally, and the grinding device 133 and the cleaning roller brush 136 are extended into the tooth groove of the gear, which is convenient for grinding rust stains on the tooth groove.

[0043] Finally, when the limiting roller 127 contacts the gear tooth groove, under the elastic force of the limiting spring 121 and the telescopic spring 125, the limiting rotating bracket 122 and the supporting rotating rod 126 are rotated. At the same time, the limiting sliding sleeve 120 drives the ejection bracket 128 to move when sliding on the outside of the limiting sliding rod 119. The elastic force of the connecting spring 131 makes the cleaning scraper 132 contact the surface of the gear tooth groove. By starting the second electric telescopic rod 114, the cleaning scraper 132 can be lifted and lowered, which is convenient for cleaning the rust stains on the gear surface. For rust stains that are tightly adhered and cannot be cleaned by the cleaning scraper 132, since the grinding device 133 and the cleaning scraper 132 compressed by the ejection spring 129 are on the same horizontal plane, the rust stains that cannot be cleaned by the cleaning scraper 132 can be polished by the grinding device 133, thereby improving the grinding accuracy. The first limiting bracket 118 is driven to rotate by the rotating motor 117, and the direction of the cleaning scraper 132 and the grinding device 133 can be changed to adapt to the tooth grooves of different angles. The rust stains on the gear surface can be preliminarily cleaned by the cleaning roller brush 136. At the same time, the clamping rotating disk 139 is rotated to make the clamping limiting card 142 slide on the outside of the threaded limiting block 138. At the same time, the clamping sliding sleeve 141 drives the clamping sliding plate 143 and the clamping arm 145 to move relative to each other, and the gear with the gear shaft can be clamped and fixed by the clamping arm 145. When the gear does not have a gear shaft, the spacing of the clamping arm 145 can be adjusted by rotating the adjusting bolt 144. By unfolding the clamping arm 145, the gear can be supported and fixed from the center hole of the gear, which is convenient for clamping and fixing the gear and improving the stability of the gear during grinding.
