Description

Technical Field

[0001] This utility model relates to the technical field of feed mechanisms for cylindrical grinding machines, specifically a feed mechanism for cylindrical grinding machines used in the machining of ball cage couplings. Background Technology

[0002] The feed mechanism of an external cylindrical grinding machine is a core functional component that enables precise movement of the grinding wheel or workpiece to complete machining of external diameters, conical surfaces, etc. Its performance directly determines the dimensional accuracy, surface quality, and machining efficiency of the workpiece. However, existing feed mechanisms for external cylindrical grinding machines have some shortcomings, such as: Application No.: CN202321579896.4 describes a feed mechanism for an external cylindrical grinding machine. This device, through a support plate, a second motor, and a second screw, facilitates the smooth movement of a clamping and rotating device located on the top of the second slide, and facilitates the left and right movement of the workpiece to be ground. However, in actual use, this device is difficult to adjust the movement of the workpiece, which may result in difficulty in adjusting the position of the workpiece.

[0003] Therefore, we propose a cylindrical grinding machine feed mechanism for machining ball cage couplings to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a feed mechanism for a cylindrical grinding machine used in the machining of ball cage couplings, so as to solve the problem mentioned in the background art that the feed mechanisms of current cylindrical grinding machines on the market are difficult to move and adjust the workpiece, thus making it difficult to adjust the position of the workpiece.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical grinding machine feed mechanism for machining ball cage couplings, comprising a main body and a grinding wheel disposed at the rear end of the main body; The main body of the device is provided with a moving mechanism, and the outside of the moving mechanism is provided with a device shell. The device shell is provided with an adjustment mechanism. The top of the device shell is provided with a clamping plate. The adjustment mechanism includes a second threaded shaft, and the outside of the second threaded shaft is provided with a threaded sleeve. The top of the threaded sleeve is provided with a fixing plate, and the top of the fixing plate is provided with a bracket. The outside of the bracket is connected with a buffer damper, and the buffer damper is fixedly connected to the clamping plate. The main body of the device is equipped with a residue box at the bottom, and the device shell is located on top of the residue box.

[0006] By setting up a moving mechanism, the device housing can move laterally, and then the device housing and clamping plate can move longitudinally. This allows the equipment to adjust the feed of the ball cage coupling workpiece during the feeding process, thereby improving the equipment's ability to adjust the feed of the ball cage coupling workpiece.

[0007] As a preferred technical solution of this utility model, the main body of the device is fixedly connected to the moving mechanism, and the moving mechanism includes a first motor, and the left end of the first motor is connected to a first threaded shaft, and the outer side of the first threaded shaft is threadedly connected to the inner side of the device shell.

[0008] The above technical solution enables the first motor to drive the first threaded shaft to rotate, and through the threaded transmission, it drives the device housing to move horizontally along the main body of the device, thereby making the workpiece more stable when moving laterally, thus increasing the adjustability of the equipment during operation.

[0009] As a preferred technical solution of this utility model, a second motor is provided inside the main body of the device, and a grooved rod is connected to the left end of the second motor. A first bevel gear set is provided on the outside of the grooved rod. A second bevel gear set is connected to the top of the first bevel gear set, and the front end of the second bevel gear set is fixedly connected to the second threaded shaft.

[0010] The above technical solution enables the second motor to transmit power to the bevel gear set through the grooved rod, and drive the second threaded shaft to rotate through two steering conversions, thereby realizing the longitudinal feed of the adjustment mechanism. The vertical transmission design of the bevel gear set saves internal space of the device housing, while ensuring the stability of power transmission.

[0011] As a preferred technical solution of this utility model, the device housing is provided with a bearing seat that is rotatably connected to the first bevel gear set, and the top of the first bevel gear set is connected to the second bevel gear set through a fixed shaft.

[0012] The above technical solution enables the bearing housing to provide rigid support for the first bevel gear set, reducing radial wobble during rotation. The fixed shaft ensures the coaxiality of the two bevel gear sets, avoiding power loss or impact noise caused by excessive meshing clearance.

[0013] As a preferred technical solution of this utility model, a sliding shaft is provided inside the device housing, and the sliding shaft is slidably connected to the threaded sleeve, and the top of the threaded sleeve is fixedly connected to the fixing plate.

[0014] The above technical solution enables the sliding shaft to provide guiding constraints for the threaded sleeve, preventing the threaded sleeve from rotating circumferentially when the second threaded shaft rotates, ensuring that the fixed plate moves smoothly along a straight line, and the sliding connection can disperse the radial force of the threaded transmission and reduce the bending deformation of the threaded shaft.

[0015] As a preferred technical solution of this utility model, the bracket is fixedly connected to the buffer damper, and an integrated control board is provided on the outer side of the grinding wheel, and the integrated control board can be electrically connected to the first motor and the second motor.

[0016] The above technical solution enables the buffer damping to absorb high-frequency vibrations during the grinding process, preventing the workpiece on the clamping plate from shifting due to vibration; while the integrated control board can precisely control the speed and direction of the two motors, realizing coordinated feeding of the moving mechanism and the adjusting mechanism, and meeting the automatic grinding requirements of complex outer cylindrical contours.

[0017] As a preferred technical solution of this utility model, a scale is provided at the front end of the main body of the device, and the scale is horizontal with the device shell.

[0018] The above technical solution enables the scale to provide an intuitive positional reference for the movement of the device housing, facilitating real-time monitoring of the feed rate by operators and thus increasing the accuracy of the equipment during feeding.

[0019] Compared with the prior art, the beneficial effects of this utility model are: by setting the moving mechanism, the device shell can move laterally and then the device shell and the clamping plate can move longitudinally, thereby enabling the device to adjust the feeding of the ball cage coupling workpiece during the feeding process, thereby improving the device's ability to adjust the feeding of the ball cage coupling workpiece. Furthermore, by setting up the moving mechanism, the first motor can drive the first threaded shaft to rotate, and through the threaded transmission, the device housing can be moved horizontally along the main body of the device, thereby making the workpiece more stable when moving laterally, thus increasing the adjustability of the equipment during operation. Furthermore, by setting up a second motor and a grooved rod, the second motor can transmit power to the bevel gear set through the grooved rod. After two steering conversions, the second threaded shaft is driven to rotate, realizing the longitudinal feed of the adjustment mechanism. The vertical transmission design of the bevel gear set saves internal space of the device housing while ensuring the stability of power transmission. Attached Figure Description

A threaded sleeve 11 is provided on the outside of the second threaded shaft 10. A fixing plate 13 is installed on the top of the threaded sleeve 11. A bracket 14 is provided on the top of the fixing plate 13. A buffer damping 15 is connected to the outside of the bracket 14. The buffer damping 15 is fixedly connected to the clamping plate 16. The main body 1 is provided with a residue box 2 at the bottom, and the device shell 5 is located on top of the residue box 2; The workpiece of the ball cage coupling is placed on the clamping plate 16. The clamping plate is flexibly connected to the bracket 14 through the buffer damping 15, which can adapt to the small size deviation of the workpiece and reduce the clamping stress. Then, the moving mechanism drives the device housing 5 to move laterally, and then the second threaded shaft 10 rotates. The threaded sleeve 11 moves longitudinally along the second threaded shaft 10 under the guidance and constraint of the sliding shaft 12. The clamping plate 16 and the workpiece move synchronously through the fixed plate 13 and the bracket 14 to complete the longitudinal feed. The main body 1 of the device is fixedly connected to the moving mechanism, and the moving mechanism includes a first motor 3, and the left end of the first motor 3 is connected to a first threaded shaft 4, and the outer side of the first threaded shaft 4 is threadedly connected to the inner side of the device shell 5. The main body 1 of the device is equipped with a second motor 6, and the left end of the second motor 6 is connected to a grooved rod 7. The outer side of the grooved rod 7 is equipped with a first bevel gear set 8. The top of the first bevel gear set 8 is connected to a second bevel gear set 9, and the front end of the second bevel gear set 9 is fixedly connected to the second threaded shaft 10. The device housing 5 has a bearing seat inside that is rotatably connected to the first bevel gear set 8, and the top of the first bevel gear set 8 is connected to the second bevel gear set 9 through a fixed shaft; The device housing 5 has a sliding shaft 12 inside, which is slidably connected to the threaded sleeve 11.

The front end of the device body 1 has a scale 19, which is horizontal with the device housing 5.

[0024] Working principle: When using the feed mechanism of the cylindrical grinding machine for machining ball cage couplings, first connect the equipment power supply and the power grid. Then, place the ball cage coupling workpiece on the clamping plate 16. The clamping plate is flexibly connected to the bracket 14 through the buffer damping 15, which can adapt to small dimensional deviations of the workpiece and reduce clamping stress. Then, the moving mechanism drives the device housing 5 to move laterally. Then, the second threaded shaft 10 rotates. The threaded sleeve 11 moves longitudinally along the second threaded shaft 10 under the guidance and constraint of the sliding shaft 12. The clamping plate 16 and the workpiece move synchronously through the fixed plate 13 and the bracket 14 to complete the longitudinal feed. Then, the grinding wheel 17 performs the machining. When the moving mechanism is running, the first motor 3 is started through the integrated control board 18, which drives the first threaded shaft 4 to rotate. The threaded connection between the first threaded shaft 4 and the inner side of the device housing 5 converts the rotational motion into linear motion, which drives the device housing 5 to move horizontally along the device body 1. The operator can observe the displacement of the device housing 5 in real time through the scale 19 at the front end of the device body 1 to ensure the accurate lateral position of the workpiece. When the adjustment mechanism is running, the second motor 6 is started, and its drive end drives the convex rod 7 to rotate. The power is transmitted to the second bevel gear set 9 through the first bevel gear set 8. After two steering conversions, the second threaded shaft 10 is driven to rotate, and then the grinding wheel 17 grinds the ball cage coupling workpiece.
