Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a grinding device for precision machining of motor shaft surfaces. Background Technology

[0002] Miniature motors are small in size and capacity, with output power generally below several hundred watts, and are motors with special requirements for application, performance, and environmental conditions. They are commonly used in control systems to realize functions such as detection, calculation, amplification, execution, or conversion of electromechanical signals or energy, or to drive mechanical loads, and can also serve as AC or DC power supplies for equipment. Examples of applications of miniature motors include disk drives, copiers, CNC machine tools, and robots.

[0003] As disclosed in the application document with application number 202220799286.4, a grinding device for processing micro motor shafts is disclosed. This utility model can adjust the gap between four grinding discs by twisting a threaded rod, which can grind shafts of various specifications and make the grinding discs fit the shaft surface better, resulting in better grinding effect and improving the practicality of the grinding device. However, when adjusting the grinding discs to fit the shaft, the threaded rod needs to be turned one by one to adjust the four grinding discs sequentially, which will affect the overall installation efficiency. In addition, the threaded rod may rotate twice during the grinding process, which will affect the fit of the grinding discs and the grinding quality.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a grinding device for the precision machining surface of motor shaft. Utility Model Content

[0005] The purpose of this invention is to provide a grinding device for the precision machining surface of a motor shaft, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface grinding device for precision machining of a motor shaft, comprising a worktable, a lead screw rotatably mounted on the left side of the inner surface of the worktable, a drive motor mounted on the left end of the lead screw penetrating the worktable, a movable seat threadedly connected to the surface of the lead screw, a grinding mechanism mounted on the upper surface of the movable seat, a support plate fixedly mounted on the right side of the upper surface of the worktable, a rotary motor fixedly mounted on the right side of the support plate, a turntable mounted on the left end of the rotary motor penetrating the support plate, and a fixing mechanism provided on the surface of the turntable.

[0007] Preferably, the grinding mechanism includes a ring plate fixedly installed on the upper surface of the movable seat, a rotating plate rotatably disposed on the inner surface of the ring plate, and four obliquely arranged sliding grooves evenly distributed on the surface of the rotating plate.

[0008] Preferably, the grinding mechanism further includes a movable rod slidably disposed on the inner surface of the groove, one end of the movable rod slidably passing through the ring plate, and a grinding disc is fixedly installed on the inner side of the ring plate.

[0009] Preferably, the grinding mechanism further includes a connecting rod fixedly installed on the right side of the rotating plate surface, the right end of the connecting rod slidingly passing through the ring plate and rotatably connected to a cylinder, and the bottom end of the cylinder being rotatably connected to the movable seat.

[0010] Preferably, the fixing mechanism includes a bidirectional screw rotatably mounted on the inner surface of the turntable, and a servo motor is mounted on the upper end of the bidirectional screw through the turntable.

[0011] Preferably, the fixing mechanism further includes an adjusting block that is threaded to both the upper and lower sides of the bidirectional screw surface, and a clamping plate is fixedly installed on the left side of the adjusting block.

[0012] Preferably, the clamping plate is arc-shaped, and the concave surfaces of the clamping plate are arranged vertically opposite each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a lead screw, a drive motor, a movable seat, a rotary motor, and a turntable. The rotary motor enables the turntable to rotate, thereby causing the rotating shaft mounted on the fixed mechanism to rotate. This, in conjunction with the grinding mechanism, performs grinding work on the rotating shaft. The drive motor drives the lead screw to rotate, which allows the movable seat to move, thereby causing the entire grinding mechanism to move left and right, and to perform uniform and comprehensive grinding on the surface of the rotating shaft.

[0015] 2. This utility model, through the arrangement of a grinding mechanism, a ring plate, a rotating plate, a sliding groove, a movable rod, a grinding disc, a connecting rod, and a cylinder, utilizes the cylinder to push the connecting rod upward, thereby causing the rotating plate to rotate. At this time, the sliding groove follows the rotating plate and rotates, thereby pushing the movable rod to extend towards the center of the ring plate, so that the grinding disc tightly adheres to the surface of the workpiece on the rotating shaft, enabling the grinding disc to automatically and stably fit with the rotating shaft for grinding work quickly and stably.

[0016] 3. This utility model, through the setting of a fixing mechanism, a bidirectional screw, a servo motor, an adjusting block, and a clamping plate, allows the servo motor to rotate the bidirectional screw, thereby causing the adjusting block to drive the clamping plate to move in opposite directions, clamping and fixing one end of the shaft, preventing the shaft from shaking or shifting during the grinding process, thus greatly improving the stability of the shaft grinding.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a surface grinding device for precision machining of a motor shaft includes a worktable 1. A lead screw 2 is rotatably mounted on the left side of the inner surface of the worktable 1. A drive motor 3 is mounted through the left end of the lead screw 2 through the worktable 1. A movable seat 4 is threadedly connected to the surface of the lead screw 2. A grinding mechanism 5 is mounted on the upper surface of the movable seat 4. A support plate 6 is fixedly mounted on the right side of the upper surface of the worktable 1. A rotary motor 7 is fixedly mounted on the right side of the surface of the support plate 6. A turntable 8 is mounted through the left end of the rotary motor 7 through the support plate 6. A fixing mechanism 9 is provided on the surface of the turntable 8.

[0024] By adopting the above technical solution, the rotary motor 7 can make the turntable 8 rotate, thereby causing the rotating shaft installed on the fixed mechanism 9 to rotate itself, and cooperate with the grinding mechanism 5 to grind the rotating shaft.

[0025] The drive motor 3 drives the lead screw 2 to rotate, which allows the movable seat 4 to move, thereby driving the entire grinding mechanism 5 to move left and right, and to perform uniform and comprehensive grinding on the surface of the rotating shaft.

[0026] Furthermore, the grinding mechanism 5 includes a ring plate 501 fixedly installed on the upper surface of the movable seat 4, and a rotating plate 502 rotatably arranged on the inner surface of the ring plate 501. The surface of the rotating plate 502 is evenly distributed with four obliquely arranged sliding grooves 503.

[0027] The grinding mechanism 5 also includes a movable rod 504 that is slidably disposed on the inner surface of the groove 503. One end of the movable rod 504 slides through the ring plate 501, and a grinding disc 505 is fixedly installed on the inner side of the ring plate 501.

[0028] The grinding mechanism 5 also includes a connecting rod 506 fixedly installed on the right side of the rotating plate 502. The right end of the connecting rod 506 slides through the ring plate 501 and is rotatably connected to a cylinder 507. The bottom end of the cylinder 507 is rotatably connected to the movable seat 4.

[0029] By adopting the above technical solution, the cylinder 507 pushes the connecting rod 506 upward, thereby causing the rotating plate 502 to rotate.

[0030] The slide 503 rotates with the rotating plate 502, thereby pushing the movable rod 504 to extend towards the middle of the ring plate 501, so that the grinding disc 505 is tightly wrapped against the surface of the workpiece on the rotating shaft.

[0031] Furthermore, the fixing mechanism 9 includes a bidirectional screw 901 rotatably mounted on the inner surface of the turntable 8, and a servo motor 902 is mounted on the upper end of the bidirectional screw 901 through the turntable 8;

[0032] The fixing mechanism 9 also includes an adjusting block 903 that is threaded to both the upper and lower sides of the surface of the bidirectional screw 901, and a clamping plate 904 is fixedly installed on the left side of the adjusting block 903;

[0033] The clamping plate 904 is set in an arc shape, and the concave surface of the arc of the clamping plate 904 is set up with the upper and lower surfaces facing each other.

[0034] By adopting the above technical solution, the servo motor 902 can make the bidirectional screw 901 rotate, thereby causing the adjusting block 903 to drive the clamping plate 904 to move in opposite directions, clamping and fixing one end of the rotating shaft.

[0035] Working principle: When using the surface grinding device for precision machining using this motor shaft, firstly, the right end of the shaft is placed between the upper and lower clamping plates 904. The servo motor 902 causes the bidirectional screw 901 to rotate, thereby causing the adjusting block 903 to drive the clamping plates 904 to move in opposite directions, clamping and fixing one end of the shaft. Then, the drive motor 3 drives the lead screw 2 to rotate, which causes the movable seat 4 to move, thereby moving the entire grinding mechanism 5, so that the left end of the shaft is inserted into the middle of the ring plate 501. Then, the cylinder 507 pushes the connecting rod 506 upward, thereby causing the rotating plate 502 to rotate. At this time, the slide groove 503 follows the rotation. The rotating plate 502 rotates, thereby pushing the movable rod 504 to extend towards the center of the ring plate 501, so that the grinding disc 505 is tightly attached to the surface of the workpiece on the rotating shaft. After the grinding disc 505 is attached to the rotating shaft, grinding can be performed. The rotating motor 7 can make the turntable 8 rotate, thereby making the rotating shaft mounted on the fixed mechanism 9 rotate itself. The grinding disc 505 can then grind the rotating shaft. During grinding, the drive motor 3 can make the lead screw 2 continue to rotate, thereby making the movable seat 4 continue to drive the entire grinding mechanism 5 to move, so as to perform uniform and comprehensive grinding on the entire surface of the rotating shaft. This is the working principle of the motor rotating shaft precision surface grinding device.
