Description

Technical Field

[0001] The invention relates to a device for assisting a retaining frame polishing process, and belongs to the field of mechanical automation. Background Art

[0002] After the cage is processed, in order to remove the dirt on the cage surface and the secondary burrs generated during the mechanical deburring process, the cage needs to be placed in a polishing machine for a certain period of time for polishing vibration to make its surface clean and burr-free. However, due to the limitations of the shape and space of the polishing machine, when the outer diameter of the cage is large, it is necessary to manually hold the cage to complete the polishing action. Usually, multiple people need to stand next to a polishing machine to hold the cage to complete the polishing process, which has low production efficiency and requires a lot of manpower. Summary of the invention

[0003] In view of the above-mentioned problem of low production efficiency, an object of the present invention is to provide a retainer auxiliary finishing device. By applying the auxiliary finishing device, the production efficiency can be greatly improved while ensuring the production quality.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a retainer auxiliary polishing device, including a column, the column is arranged in a vertical direction, a rotating bracket can be raised and lowered on the column, the rotating bracket is arranged horizontally, and the rotating bracket can be rotatably connected to the column, the rotating bracket is connected to a plurality of rollers through a mounting frame, the plurality of rollers are driven to rotate by a driving structure, a retainer is suspended on the roller, and the retainer rotates with the rotation of the roller.

[0005] Based on the above technical solution, it should be noted that the polishing device of the utility model can be adjusted in vertical, horizontal and angular positions according to the size of the holder, so that holders of different specifications can all fall into the cylinder of the polishing machine for polishing. Since the holder is suspended, only the lower part of the holder enters the cylinder of the polishing machine, and the upper part is supported and driven to rotate by rollers. Therefore, the holder is not affected by the vibration of the polishing and has high stability. The holder is driven to rotate by the roller to ensure that every part of the holder can enter the cylinder of the polishing machine, ensuring the uniformity of the polishing process. The rotating bracket can be rotatably connected to the column, so that the holder can rotate with the rotating bracket to the outside of the polishing machine for replacement, and the holder can also be transferred from one polishing machine to another, so that the polishing machine can be repaired and replaced without affecting the polishing operation.

[0006] Furthermore, the side surface of the roller is formed by alternating planes and arcs, and the retainer is suspended on the side surface of the roller. The two planes are arranged opposite to the two arcs, and the length of the plane is greater than the length of the arc. When the contact surface between the roller and the retainer changes, it can play a certain role in promoting the retainer.

[0007] Based on the above technical solution, it should be noted that the motor drives the elliptical profiled roller to move, and the two arcs where the roller contacts the holder generate thrust similar to that of a human hand, so that the holder and the abrasive in the barrel of the polishing machine move relative to each other to achieve a cleaning effect. The rotating shaft drives the profiled roller to rotate, and each rotation of the shaft drives the roller forward twice. The holder rotates in the abrasive without slipping. By applying this automatically rotating roller, production efficiency can be greatly improved.

[0008] Furthermore, a connecting plate is slidably mounted on the column via a linear guide rail, and the rotating bracket is mounted on the connecting plate.

[0009] Furthermore, a servo motor and a reducer are installed on the top of the column, sprockets are installed on both sides of the output shaft of the reducer, a chain is installed on the sprocket, the connecting plate is fixed to the chain, the rotating bracket is connected to the chain through the connecting plate, the servo motor is started, and the rotating bracket is raised and lowered with the retraction and extension of the chain. The servo motor and the chain provide driving force for the lifting and lowering of the rotating bracket, and the linear guide rail on the column provides guidance for the lifting and lowering of the rotating bracket.

[0010] Furthermore, one end of the chain is connected to the connecting plate, and the other end of the chain is connected to a counterweight block, and the counterweight block is used to balance the weight at both ends of the chain.

[0011] Furthermore, a rotating assembly is fixedly installed on the connecting plate, and a rotating bracket is rotatably connected to the column through the rotating assembly. The rotating assembly includes an axis bracket and a sliding bearing vertically installed on the axis bracket. A positioning cylinder for locking the sliding bearing is provided on the axis bracket. The axis bracket is fixedly connected to the connecting plate, and the rotating bracket is connected to the sliding bearing and rotates and swings around the sliding bearing as an axis.

[0012] Based on the above technical solution, it should be noted that the shaft bracket includes an upper top plate and a lower bottom plate connected to the two ends of the sliding bearing. The end plate at the end of the rotating bracket contacts the end surface of the sliding bearing. The positioning cylinder presses the end plate tightly to lock the sliding bearing, so that the rotating bracket is positioned at a predetermined position and no longer rotates.

[0013] Furthermore, an inclined support frame is connected above and / or below the rotating bracket, one end of the support frame is fixedly connected to the rotating bracket, and the other end of the support frame is rotatably connected to the column through a rotating assembly, and the rotating assembly connecting the rotating bracket and the rotating assembly connecting the support frame are coaxially arranged. The rotating bracket, the support frame and the column form a stable triangular structure, and the support frame supports the rotating bracket, reducing the stress on the connecting end of the rotating bracket, which can effectively ensure the stability of the rotating bracket. The two rotating assemblies are coaxially arranged to ensure that the rotation center of the rotating bracket does not change, effectively reducing the occurrence of problems such as wear and jamming.

[0014] Furthermore, the mounting frame includes a fixing device, a positioning plate and a plurality of fixing plates, the fixing device is connected to the rotating bracket, the positioning plate is connected to the fixing device, a plurality of fixing plates are evenly arranged on the positioning plate along the circumference, each fixing plate is correspondingly arranged with a roller, the roller is rotatably connected to the fixing plate through a roller shaft and a bearing seat, and support is provided for the roller device through the bearing in the bearing seat.

[0015] Based on the above technical solution, it should be noted that the number of rollers can be determined according to the size of the suspended cage, 2-5 is optimal, and each roller is installed on a corresponding fixed plate, but the cage and the roller are not necessarily in a one-to-one correspondence. This device is suitable for cages of various specifications. When replacing large-sized cages for processing, the cages can be suspended on the rollers at intervals to avoid interference. The fixing device is fixed to the appropriate position of the rotating bracket by bolts, and the installation position of the fixing device can be adjusted according to the size of the cage. The positioning plate is horizontally set and suspended under the rotating bracket by the fixing device, and the fixing plate is vertically set under the positioning plate to avoid interference between the cage and the finishing device.

[0016] Furthermore, the driving structure includes a speed regulating motor and a reduction gearbox, which are fixed on a fixed plate and drive the roller shaft through a synchronous belt, thereby driving the roller to rotate; two adjustable baffles are mounted on the roller, and the two baffles are respectively located at both ends of the retaining frame, so that the retaining frame does not tilt during rotation.

[0017] Based on the above technical solution, it should be noted that the inner hole of the baffle matches the shape of the roller, and the baffle rotates together with the roller to ensure the stability of the positional relationship. Each roller corresponds to an independent drive structure to achieve the adjustment of the speed of a single roller. The speed regulating motor is connected to the reduction box and is installed on the fixed plate by bolts. The torque is transmitted to the rotating shaft through the pulley and the belt. The special-shaped roller is connected to the rotating shaft through a flat key, and a rubber pad is added to the outside of the special-shaped roller to protect the retaining frame while increasing the friction. There are four T-slots on the outside of the special-shaped roller for installing the fixing frame. By adjusting the position of the fixing frame on the roller, the spacing of the baffle is adjusted to adapt to retaining frames of different widths. When working, start the speed regulating motor, which in turn drives the pulley to operate, and transmits the motion to the roller through the pulley and the rotating shaft. In the finishing machine, the abrasive will move in the direction of vibration. In order to coordinate the movement of the roller with the movement of the abrasive, the commonly used round roller is not used, but the special-shaped roller shown in the figure above is used. When the retaining frame rotates, the arcs on both sides of the roller play a certain boosting role, and together push the retaining frame in the abrasive to complete the finishing process.

[0018] Furthermore, the speed regulating motor is equipped with a speed regulator, which is connected to the positioning plate. The speed regulator transmits a speed signal to the speed regulating motor and controls the rotation speed.

[0019] Furthermore, a clamp is provided at one end of the roller away from the driving structure, and the clamp fixes the end plates on both sides of the roller on the shaft for axial and radial positioning.

[0020] Furthermore, a rubber pad is provided on the side surface of the roller to increase the friction between the roller and the inner wall of the retaining frame, so as to facilitate the rotation of the retaining frame by the rotation of the roller.

[0021] Furthermore, the upright column is fixed on a base surface by anchor bolts. The base surface is the ground or other plane.

[0022] The column is fixed to the ground with anchor bolts. A servo motor is installed on the top of the column, which controls the movement of the connecting plate through sprockets and chains, and uses linear guides for orientation. A rotating bracket is installed on the connecting plate, and the large fixed plate is installed on the rotating bracket. Four small fixed plates are connected to the large fixed plate, and the motor and reducer are installed on the small fixed plate. The torque is transmitted through the synchronous belt to drive the special-shaped roller to rotate, thereby driving the cage to rotate and complete the finishing action.

[0023] The beneficial effects of the present invention are as follows: the polishing device of the present invention is suitable for polishing operations on retaining frames of different specifications, has strong adaptability and high stability, supports and drives the retaining frame through the equipment, reduces manual intervention, saves manpower, and ensures processing quality.
