Description

Technical Field

[0001] The invention belongs to the technical field of mechanical parts processing, and in particular relates to a grinding device for mechanical parts processing. Background Art

[0002] Mechanical parts processing refers to the process of processing raw materials through a series of processes to ensure that the part's shape, size, and performance meet design requirements. This process encompasses a variety of techniques, including cutting, where cutting tools are used to remove material to achieve the desired shape and size; and forging, where pressure is applied to metal to induce plastic deformation, thereby achieving a specific microstructure and properties. Part polishing is a crucial surface treatment process in mechanical parts processing. Its primary purpose is to remove surface defects such as burrs and scale, thereby improving surface finish and quality. During polishing, the appropriate abrasive and polishing method must be selected based on the part's precision requirements. For parts with lower precision requirements, a coarser abrasive can be used for initial polishing to quickly remove significant surface defects. For parts with higher precision requirements, finer abrasives are used for extended polishing to ensure that the surface meets the specified roughness and flatness requirements. Polished parts can better meet operational requirements and improve overall product performance and reliability.

[0003] When grinding tubular parts, steel pipe grinding and polishing equipment is used. Existing steel pipe grinding and polishing equipment is mostly divided into two forms. In the first form of grinding equipment, the position of the steel pipe remains unchanged during grinding. The equipment drives the steel pipe to rotate and grinds and polishes the steel pipe through a translatable grinding head. For example, the Chinese utility model patent with announcement number CN210139294U supports the steel pipe through a supporting mechanism, drives the steel pipe to rotate through a rotating drive mechanism, and grinds and polishes the steel pipe through a translatable grinding mechanism. Although this type of grinding equipment can grind and polish steel pipes, since the translation distance of its grinding mechanism is limited by the size of the equipment itself, this type of grinding equipment can only process steel pipes with a length shorter than the equipment, and cannot process longer steel pipes. In order to adapt to longer steel pipes, this type of grinding equipment is often longer in size and occupies a larger area, which will cause a waste of factory space.

[0004] Another form of grinding equipment has a grinding mechanism whose position remains unchanged during grinding, and a feed roller and a set of inclined guide wheels are used to drive the steel pipe to rotate and translate, so that the grinding mechanism can grind the steel pipe as a whole. For example, the Chinese invention patent with publication number CN119077595A drives the feed roller to rotate through a motor, a sprocket and a chain, thereby driving the steel pipe to rotate. The steel pipe drives the inclined guide wheel to rotate through friction. Under the oblique guidance of the inclined guide wheel, the stainless steel pipe rotates while being transported to the polishing assembly at a stable rate. Although the grinding device of this structure can push the steel pipe to translate and can be used to process steel pipes longer than the device itself, this grinding device uses a feed roller and a set of inclined guide wheels to drive the steel pipe to rotate and translate, so that the steel pipe can be polished as a whole. The rotation of the roller and the steel pipe drives the rotation of the inclined guide wheel, thereby realizing the axial movement of the steel pipe. The speed of the axial movement of the steel pipe is highly positively correlated with the rotation speed of the steel pipe itself. When processing steel pipes of different specifications, different roughness and different grinding precisions, the device cannot change the ratio of the steel pipe rotation speed to the steel pipe translation speed, and the moving speed of the steel pipe remains constant throughout the grinding and polishing process. Therefore, it is impossible to accurately adjust the length of time that the grinding mechanism and the local contact between the steel pipe are in accordance with the processing requirements. In addition, the device uses structures such as vibration sensors, controllers, motors and negative pressure adsorption mechanisms to maintain the stability of the steel pipe and avoid vibration of the steel pipe. Its anti-vibration mechanism has the problems of complex structure and limited anti-vibration effect.

[0005] Therefore, it is urgent to provide a grinding device for machining mechanical parts to solve the above problems. Summary of the Invention

[0008] Furthermore, the mounting seat mechanism includes a base plate, a first gantry is welded and fixed to one side of the top end of the base plate, a through hole and a sliding hole are provided on the first gantry, a connecting frame is welded on the base plate, a first mounting frame is welded to the top of the base plate, a first protective cover is fixed on the first mounting frame, a second mounting frame is welded on the base plate, a second protective cover is fixed on the second mounting frame, and a second gantry is welded to the other side of the top end of the base plate.

[0009] Through the above technical solution, the base plate, the first gantry and the second gantry are all made of stainless steel. The second gantry has the same structure as the first gantry. The connecting frame and the first mounting frame are both provided with circular holes for fixing bearings.

[0011] Through the above technical solution, when the first motor is started, the first pulley drives the second pulley to rotate through the transmission belt, thereby causing the rubber roller and the third pulley to rotate. The inner rings of the first bearing and the second bearing are fixed to the rubber roller, and the outer rings of the first bearing and the second bearing are respectively fixed to the first mounting frame and a connecting frame. When the rubber roller rotates, the rubber roller can drive the workpiece to rotate circumferentially.

[0013] Through the above technical solution, the radius of the hollow roller is equal to the radius of the rubber roller. When the third pulley rotates, the synchronous belt can drive the fourth pulley to rotate synchronously, so that the hollow roller and the rubber roller rotate synchronously. The multiple hollow grooves are in an equidistant annular array and an equidistant linear array. The connecting ears are fixed on both sides of each hollow groove on the inner wall of the hollow roller. There are multiple worm gears, and the position of each worm gear corresponds to the position of the hollow groove. The edge of the worm gear is slightly higher than the hollow groove. The inner rings of the third bearing and the fourth bearing are fixed to the hollow roller, and the outer rings of the third bearing and the fourth bearing are respectively fixed to two mutually aligned connecting frames.

[0014] Furthermore, the driving mechanism includes a second motor fixed on a second mounting frame, a worm is fixed to an output end of the second motor, the outside of the worm is covered with a rubber layer, and a fifth bearing is fixed to the end of the worm.

[0015] Through the above technical solution, the second motor is an adjustable-speed motor, and the worm is meshed with the worm wheel. When the second motor is started, the worm will rotate, thereby driving the worm wheel to rotate. When the worm wheel rotates, its outer edge can push the workpiece, thereby causing the workpiece to move axially. The rubber layer can effectively increase the friction between the worm wheel and the workpiece, and can also avoid wear of the worm wheel. By changing the speed of the second motor, the device can change the moving speed of the workpiece, and thereby change the contact time between the workpiece surface and the grinding wheel, so that the device can be suitable for workpieces of different specifications and workpieces of different roughness.

[0016] Furthermore, the first support frame mechanism includes a frame body bolted to the bottom plate, a reinforcing support is welded on the inner side of the frame body, at least two fixing bolts are passed through the frame body, and a guide wheel is rotatably connected to the frame body.

[0017] Through the above technical solution, the frame is made of stainless steel, the reinforcing support can effectively improve the strength of the frame, the fixing bolts fix the frame to the base plate, the guide wheel can support the workpiece, the guide wheel is dumbbell-shaped, and the expanded parts at both ends are hemispherical, and the radius of the hemisphere is equal to the radius of the rubber roller. Therefore, the curvature of the hemispherical section of the guide wheel is the same as the curvature of the cross-section of the hollow roller and the rubber roller, so that the guide wheel can be suitable for workpieces of different specifications. The second support frame mechanism has the same structure as the first support frame mechanism, and the first support frame mechanism and the second support frame mechanism are respectively arranged at the two ends of the rubber roller mechanism and the roller mechanism, so that the device can provide support when loading and unloading the workpiece.

[0019] When the workpiece is placed between the rubber roller and the hollow roller, the staff can operate the electric cylinder to make the lifting plate drive the T-shaped frame and the rotating frame to press down, thereby making the rolling ball press the workpiece to prevent the workpiece from vibrating or tilting. The rolling ball can rotate in any direction, so the rolling ball will not hinder the rotation and axial movement of the workpiece when pressing the workpiece. The second pressing tube mechanism has the same structure as the first pressing tube mechanism. When the workpiece moves below the second pressing tube mechanism, the second pressing tube mechanism can also press the workpiece, further improving the stability of the workpiece during the grinding process, and also preventing the tail end of the workpiece from lifting during unloading.

[0021] Through the above technical solution, the lifting frame is slidably connected to the electric guide rail, and the internal thread groove is threadedly connected to the lead screw. When the drive motor is started, the lifting frame will rise or fall along the lead screw, thereby changing the height of the grinding mechanism, so that the device can be suitable for workpieces of different radii.

[0022] Furthermore, a grinding motor is fixed on the reducer housing, and the output end of the grinding motor is connected to a rotating shaft, a spur gear 1 is fixed on the rotating shaft, a double gear is meshed on one side of the spur gear 1, and a spur gear 2 is meshed on the other side of the double gear, a driving shaft is fixed on the inner side of the spur gear 2, a grinding wheel is fixed on one end of the driving shaft, and a hollow drum is fixed on the other end of the driving shaft, a plurality of oil outlet holes are opened on the hollow drum, a rotating joint is fixed on the hollow drum, and an oiled cotton sleeve is fixed on the outside of the hollow drum.

The flat gear 1, the double gear and the flat gear 2 form a reduction gear set, thereby reducing the output speed of the grinding motor and increasing the torque output by the grinding motor, and transmitting power to the drive shaft. When the drive shaft rotates, the grinding wheel will also rotate accordingly, thereby grinding the workpiece. At the same time, the hollow drum will also drive the oiled cotton sleeve to rotate, thereby coating the polished part with a layer of anti-rust oil to prevent subsequent rust on the polished workpiece.

[0024] Furthermore, the oil supply mechanism includes a rust-proof oil tank fixed on the base plate, a refueling port is opened on the rust-proof oil tank, a water pump is fixed on the top of the rust-proof oil tank, the input end of the water pump is connected to an oil extraction pipe, and the output end of the rust-proof oil tank is connected to an oil delivery hose.

The two-linked gear 911 and the flat gear 912 are both located inside the reducer housing 907 and are connected to the reducer housing 907. 07 Rotational connection, flat gear 1 910, double gear 911 and flat gear 2 912 form a reduction gear set, thereby reducing the output speed of the grinding motor 908 and increasing the torque output by the grinding motor 908, and transmitting power to the drive shaft 913. When the drive shaft 913 rotates, the grinding wheel 914 will also rotate accordingly, thereby grinding the workpiece. At the same time, the hollow drum 915 will also drive the oiled cotton sleeve 918 to rotate, thereby coating the polished part with a layer of anti-rust oil to prevent subsequent rust on the polished workpiece.

[0037] refer to Figure 1 and Figure 13, an oil supply mechanism 10 is fixed on the mounting base mechanism 1, and the oil supply mechanism 10 includes a rust-proof oil tank 1001 fixed on the bottom plate 101, a refueling port 1002 is opened on the rust-proof oil tank 1001, a water pump 1003 is fixed on the top of the rust-proof oil tank 1001, the input end of the water pump 1003 is connected to the oil extraction pipe 1004, the output end of the rust-proof oil tank 1001 is connected to the oil delivery hose 1005, the other end of the oil delivery hose 1005 is connected to the rotary joint 917, and the interior of the rust-proof oil tank 1001 is filled with Anti-rust oil, the water pump 1003 can regularly extract a certain amount of anti-rust oil from the anti-rust oil tank 1001 through the oil extraction pipe 1004, and transport the anti-rust oil to the hollow drum 915 through the oil delivery hose 1005 and the rotating joint 917. The anti-rust oil in the hollow drum 915 will seep out from the oil outlet 916 under the action of gravity and centrifugal force, and wet the oiled cotton sleeve 918, so that the oiled cotton sleeve 918 can be coated with anti-rust oil on the surface of the workpiece, and can supply oil to the oiled cotton sleeve 918 during long-term grinding operations.

[0038] The working principle of this embodiment is as follows: the staff places the workpiece on the first support frame mechanism 5 and between the rubber roller mechanism 2 and the roller mechanism 3, and the first pressing tube mechanism 7 presses down the workpiece, thereby improving the stability of the workpiece. The rubber roller mechanism 2 and the roller mechanism 3 rotate in the same direction, driving the workpiece to rotate in the opposite direction. At the same time, the driving mechanism 4 and the roller mechanism 3 drive the workpiece to move horizontally. When the workpiece moves to the bottom of the grinding mechanism 9, the grinding mechanism 9 presses down and grinds the rotating workpiece. The first motor 201 can adjust the rotation speed of the workpiece, and the second motor 401 can adjust the translation speed of the workpiece, so that the device can be suitable for grinding workpieces of different specifications and different roughness. At the same time, the grinding mechanism 9 can also apply anti-rust oil to the workpiece to prevent the workpiece from rusting after grinding. When one end of the workpiece moves to the bottom of the second pressing tube mechanism 8, the second pressing tube mechanism 8 presses the workpiece to further improve its stability. The second pressing tube mechanism 8 cooperates with the second support frame mechanism 6 to prevent the tail end of the workpiece from tilting during unloading.
