Description

Technical Field

[0001] This invention relates to the field of workpiece grinding equipment technology, and in particular to a grinding equipment for a washing machine drum bracket. Background Technology

[0002] The drum support bracket (commonly known as the "tripod") of a drum washing machine is the core load-bearing component connecting the drive shaft and the inner drum. It is assembled with the motor shaft and bearing seat at the center and fixed to the bottom of the inner drum at the three ends. When rotating at high speed, it transmits torque and disperses centrifugal force, directly determining the vibration, noise and lifespan of the whole machine. Its material is mostly cast aluminum or cast iron. After die casting or casting blanks, the end face of the support arm and the surface of the connecting hole need to be ground to ensure dimensional accuracy, geometric tolerance and surface finish, and meet the requirements of high-speed dynamic balance and assembly sealing.

[0003] However, there are some shortcomings in the current design of roller support grinding equipment: First, existing grinding equipment does not have an auxiliary calibration structure for the grinding roller that can be quickly calibrated. The grinding roller is a wear-prone part, and long-term continuous grinding will cause wear deviations in the roller body. If calibration and correction cannot be completed in time, it will directly reduce the grinding accuracy of the workpiece. The calibration process of traditional grinding equipment is cumbersome. It is necessary to first use a special measuring device to detect the wear amount and wear location of the grinding roller and obtain accurate wear parameters before subsequent calibration and adjustment work can be carried out. The overall calibration process is complicated and time-consuming, and cannot achieve rapid and accurate calibration of the grinding roller. Secondly, existing grinding equipment lacks a structure for rapid detection of the grinding accuracy of finished products. After the roller support is ground, it is necessary to manually use measuring tools to check the accuracy parameters of each grinding end face of the support to determine whether the workpiece is qualified. This manual inspection method is cumbersome and inefficient, and cannot achieve rapid batch inspection of grinding accuracy. It is difficult to adapt to the inspection requirements of modern high-efficiency production lines, thus limiting the overall processing efficiency of roller supports. Summary of the Invention

[0004] To address the above problems, one objective of this invention is to overcome these shortcomings, and more specifically, to provide a grinding equipment for a washing machine drum bracket, which facilitates the calibration of the grinding roller, simplifies the calibration steps, and allows for simultaneous inspection of the processed end face, thereby improving inspection efficiency.

[0007] Preferably, a base plate is installed at the bottom of the gear plate, and a main gear controlled by a motor is rotatably installed on the base plate. A drive screw is rotatably installed inside each set of slides, and a secondary gear is fixedly installed at the end of the drive screw. The secondary gear is connected to the main gear in a transmission connection.

[0008] Preferably, a movable frame is slidably arranged inside the slide groove. The upper end of the movable frame is provided with an overlap groove, and the upper end of the movable frame is provided with a base. The two sides of the base are inserted into the overlap groove, and two sets of clamps controlled by a double-headed screw are slidably installed on the upper end of the base.

[0009] Preferably, an electric cylinder is installed on the moving platform, and a lifting component is slidably installed on the piston rod on the bottom side of the electric cylinder. The lifting component cannot rotate on the piston rod, and a cylindrical rod is arranged in a ring shape at the bottom of the lifting component.

[0010] Preferably, a mounting bracket is rotatably mounted on the bottom of the piston rod at the lower end of the electric cylinder. The upper end of the mounting bracket can be inserted into the cylindrical rod at the bottom of the lifting component, and the side wall of the mounting bracket is symmetrically provided with end holes.

[0011] Preferably, the side end of the mounting bracket is provided with an adjustment groove, an adjustment screw is rotatably installed inside the adjustment groove, and a lifting plate is slidably installed inside the adjustment groove. A grinding roller controlled by a motor is rotatably installed on the side end of the lifting plate, and the lifting plate is threadedly connected to the adjustment screw.

[0012] Preferably, a reference rod is slidably mounted on the outer side of the mounting bracket. The reference rod is rotatable on the mounting bracket, and a spring is provided between the reference rod and the outer side of the mounting bracket. A fixing head is provided at the side end of the reference rod, and the fixing head is inserted into the end hole.

[0015] 1. In this invention, by setting a rotatable reference rod on the outside of the mounting frame, and cooperating with the adjusting screw and lifting plate inside the adjusting groove, the grinding roller will develop wear deviation due to long-term use during the daily grinding process of the equipment. When calibrating it, there is no need to use a special measuring device to detect the wear parameters. By flipping the reference rod to the lower end of the mounting frame, and then rotating the adjusting screw to drive the lifting plate to move the worn grinding roller down until the bottom surface of the grinding roller is in contact with the reference rod, the position calibration can be completed quickly. This calibration method can simplify the traditional cumbersome calibration process, shorten the calibration time, and facilitate the operation of workers.

[0016] 2. In this invention, a central frame with test rods is set at the upper end of the cover, and an electrical connection structure is used between the test contacts and the test lamps. After the workpiece is ground, the operator presses down on the elastically installed central frame, which drives the three sets of test rods to move down synchronously along the guide groove of the cover, so that the test contacts contact the grinding end face of the bracket. By observing whether the three sets of test lamps light up synchronously, it is possible to quickly determine whether the grinding position accuracy of the three points of the bracket is consistent and whether there is a grinding deviation. This can greatly improve the detection efficiency of the traditional inefficient detection method of manual measurement one by one, and can adapt to the detection needs of batch production on the assembly line.

[0032] This application achieves rapid calibration of the grinding roller 5031's processing position by rotating the mounting rod 504 on the mounting frame 5. When the mounting rod 504 is flipped to the lower end of the mounting frame 5, the bottom surface of the grinding roller 5031 is in contact with the mounting rod 504. Normally, the mounting rod 504 is fixed above the mounting frame 5 when flipped. As the grinding roller 5031 is used, its outer wall will wear down. At this time, by flipping the mounting rod 504 to the lower end of the mounting frame 5 and then rotating the adjusting screw 5021, the lifting plate 503 moves the grinding roller 5031 downward and makes the grinding roller 5031 re-in contact with the mounting rod 504. This avoids processing errors caused by wear of the grinding roller 5031.

[0033] As a second embodiment of the present invention, based on the first embodiment, such as Figure 9 and 10As shown, an electric cylinder 403 is installed on the moving platform 401.

The upper end of the mounting bracket 5 can be inserted into the cylindrical rod at the bottom of the lifting component 4031, and end holes 501 are symmetrically arranged on the side wall of the mounting bracket 5. An adjusting groove 502 is provided at the side end of the mounting bracket 5. An adjusting screw 5021 is rotatably installed inside the adjusting groove 502, and a lifting component is slidably installed inside the adjusting groove 502. A lowering plate 503 has a grinding roller 5031 rotatably mounted on its side end, controlled by a motor, and the lowering plate 503 is threadedly connected to an adjusting screw 5021; a reference rod 504 is slidably mounted on the outer side of the mounting frame 5, the reference rod 504 can rotate on the mounting frame 5, and a spring is provided between the reference rod 504 and the outer side of the mounting frame 5; a fixing head 5041 is provided on the side end of the reference rod 504, and the fixing head 5041 is inserted into the end hole 501; a movable frame 4 is provided, in which a moving table 401 can be slidably mounted; a side rod 402 is provided, through which the movable frame 4 can be inserted into the cover 3; A positioning hole 4021 is provided for positioning and fixing the side rod 402 on the connecting block 302; an electric cylinder 403 is provided to control the feeding of the grinding roller 5031; a lifting component 4031 is provided, which, through its engagement with the mounting frame 5, allows the mounting frame 5 to be fixed on the piston rod of the electric cylinder 403; the mounting frame 5 is provided for mounting the grinding roller 5031; an end hole 501 is provided, which, by inserting the fixing head 5041 on the reference rod 504 into the end hole 501 at different positions, allows the reference rod 504 to be fixed on the mounting frame 5 at different angles; an adjustment groove 502 is provided for... A lifting plate 503 is slidably installed in the adjusting groove 502; an adjusting screw 5021 is provided, which can be used to adjust the position of the lifting plate 503 in the adjusting groove 502; the lifting plate 503 is provided, which can be used to movably install the grinding roller 5031 onto the mounting frame 5; the grinding roller 5031 is provided, which is used to perform grinding processing on the roller support; a reference rod 504 is provided, which can be used to calibrate the position of the grinding roller 5031; a fixing head 5041 is provided, which can be used to fix the reference rod 504 on the mounting frame 5 by inserting the fixing head 5041 into the end hole 501.

[0034] As a third embodiment of the present invention, based on embodiment one, such as Figure 7As shown, a central frame 6 is slidably mounted on the upper end of the cover 3. A spring is installed between the central frame 6 and the upper end face of the cover 3. Three sets of side frames 601, corresponding to the positions of the guide groove 301, are arranged in a ring around the central frame 6. Scale lines are provided on the outside of the side frames 601. A test rod 602 is slidably mounted inside the side frames 601 via screws. The test rod 602 is slidably engaged with the guide groove 301. A test contact 6021 is provided at the bottom of the test rod 602, and a test lamp group 6022 is provided at the top of the test rod 602. The test lamp group 6022 is electrically connected to the test contact 6021. When the test contact 6021... When in contact with an object, the test light group 6022 will emit light, and the test lights 6022 on the three test rods 602 will be at the same horizontal height. A center frame 6 is set up, and a side frame 601 can be installed on the center frame 6. A side frame 601 is set up, and a test rod 602 can be installed on the side frame 601. By rotating the screw inside the side frame 601, the installation position of the test rod 602 on the side frame 601 can be adjusted. The test rod 602 is set up, and by contacting the test contact 6021 on the test rod 602 with the roller support, it is observed whether the three test light groups 6022 can light up synchronously, thereby judging the machining accuracy of each position of the roller support.

[0035] This application involves installing a center frame 6 at the upper end of the main body 1, and having the test rods 602 on the center frame 6 pass through the guide groove 301. After the roller bracket is ground, the center frame 6 is pressed down, causing the three sets of test rods 602 to descend synchronously. When the test contact 6021 at the bottom of the test rod 602 contacts the bracket, the test light group 6022 can be activated. Observe whether the test light groups 6022 on the three sets of test rods 602 can light up synchronously. If they can light up synchronously, it proves that the triangular bracket maintains a uniform grinding precision at each position. If the test light group 6022 at any position fails to light up, it proves that there is a deviation in the grinding of the bracket. In this way, rapid testing of the bracket after grinding can be completed.

[0036] The specific usage and function of this embodiment are as follows: In this invention, such as Figures 1 to 10As shown, the main gear 2021 is driven by a motor to rotate. The main gear 2021 synchronously meshes with three sets of auxiliary gears 2031, driving each set of drive screws 203 to rotate. This causes the movable frame 204 inside the slide groove 201 to slide to the corresponding position. Then, the roller support to be processed is placed on the base 205 on the top of the gear plate 2. The double-ended screw is rotated so that the two sets of clamping plates 2051 clamp and fix the roller triangular support in the center. The movable frame 4 is fixed inside the cover 3 by using the positioning hole 4021 through the positioning rod 303. During the grinding operation, the moving table 401 is moved laterally by a screw, and the piston rod is extended and retracted by an electric cylinder 403, causing the mounting frame 5 to move downwards as a whole, so that the grinding roller 5031 is close to the end face to be processed of the roller support. The grinding roller 5031 is rotated by a motor, and the end face and hole surface of the triangular support are ground. The grinding debris generated during the processing can fall into the collection part 104 at the bottom of the main body 1 for centralized collection. At the same time, the drive gear 1021 on the outside of the main body 1 is driven by a motor to rotate, driving the gear disk 2 to rotate as a whole. Rotate and adjust the processing position of the roller bracket to achieve grinding at multiple positions. After the grinding roller 5031 is used up, flip the reference rod 504 to the lower end of the mounting bracket 5, then rotate the adjusting screw 5021 and drive the lifting plate 503 to slide vertically, causing the grinding roller 5031 to move down until it precisely fits against the reference rod 504, so as to quickly complete the wear calibration of the grinding roller 5031. After calibration, reset the reference rod 504 and fix it by inserting the fixing head 5041 into the end hole 501. When the grinding of a single roller bracket is completed, press down. The central frame 6 at the upper end of the pressure cover 3 causes the three sets of side frames 601 and the test rod 602 to move down synchronously along the guide groove 301, so that the test contact 6021 at the bottom of the test rod 602 contacts the grinding end face of the bracket. By observing whether the three sets of test lights 6022 light up synchronously, it is determined whether the overall grinding accuracy of the bracket meets the standard. After the test is completed, the central frame 6 is released and the central frame 6 automatically resets under the action of the spring. If it is qualified, the finished product can be removed and the processing of the next bracket can be carried out. If it is not qualified, it needs to be repaired.
