Abstract
Description
Technical Field
[0001] This utility model applies to the field of surface grinding technology, and particularly relates to a surface grinding machine for machining precision workpieces. Background Technology
[0002] Currently, grinding machines are machine tools that use abrasives to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasives such as oilstones, abrasive belts, and free abrasives for processing. Nowadays, they are often used for grinding the surface of precision workpieces.
[0003] However, when using surface grinders to grind precision workpieces, to prevent lateral displacement of the workpiece during grinding and thus reduce processing efficiency, a limiting mechanism is often used to restrain the workpiece. However, this limiting mechanism, limited by its relatively simple structure and function, can only restrain the outer wall of the workpiece and cannot center it. This results in inconsistent lateral movement of the grinding rollers during translation, making adjustment difficult and leading to varying grinding precision at different locations on the workpiece surface, thus affecting processing quality. Therefore, we propose a surface grinder for machining precision workpieces. Utility Model Content
[0004] The main objective of this invention is to provide a surface grinder for machining precision workpieces, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A surface grinder for machining precision workpieces includes a support table, an electric slide rail is provided on the top side of the support table, a drive frame is drivenly connected to the top of the electric slide rail, and a grinding roller is slidably arranged on the side of the drive frame.
[0007] A placement platform is fixedly installed on the top surface of the support machine base. Fixed plates are fixedly installed at both ends of the side of the support machine base. A fixed frame is fixedly installed at the middle of the side of the fixed plate. A connecting frame is fixedly installed between the two sets of fixed frames.
[0008] The fixed frame is equipped with a bidirectional adjustment mechanism. Abutment plates are slidably installed on both sides of the top of the placement platform. A conversion mechanism is provided between the outside of the fixed frame and the outside of the abutment plates, and the conversion mechanism and the bidirectional adjustment mechanism are connected in a transmission manner. The connecting frame is equipped with a synchronous rotation mechanism, and the synchronous rotation mechanism and the bidirectional adjustment mechanism are connected in a transmission manner.
[0009] As an optional solution to the technical solution of this application, the bidirectional adjustment mechanism includes a bidirectional lead screw, and transmission sleeves are threadedly connected to both sides of the bidirectional lead screw. A transmission rod is fixedly installed in the middle of the outer side of each transmission sleeve. Sliding plates are slidably installed at both ends of the side of the fixed frame, and the top of the side of the transmission rod is fixedly connected to the outer wall of the sliding plate.
[0010] As an optional solution to the technical solution of this application, the conversion mechanism includes a push rod, a fixing block is fixedly installed at the middle of the outer side of each sliding plate, and a push rod is inclinedly hinged to the side of each fixing block through a rotating shaft, and the top of the side of the push rod is hinged to the outer wall of the abutment plate through a rotating shaft.
[0011] As an optional solution to the technical solution of this application, the synchronous rotation mechanism includes a transmission chain ring and a transmission sprocket. A rotating rod is rotatably mounted on both sides of the inner side of the connecting frame through bearings, and the top edge of the rotating rod extends rotatably into the inner side of the fixed frame through bearings. The top edge of the rotating rod is fixedly connected to the top edge of the bidirectional lead screw. A transmission sprocket is fixedly sleeved on the outer side of each rotating rod. A transmission chain ring is meshed between the outer edges of the two sets of transmission sprockets, and both the transmission sprocket and the transmission chain ring are rotatably disposed inside the connecting frame.
[0012] As an optional solution to the technical solution of this application, a servo motor is fixedly installed on the outside of the connecting frame, and the side of the servo motor drive shaft is fixedly connected to the top of the side of the rotating rod through a coupling.
[0013] As an optional solution to the technical solution of this application, a limiting groove is provided at the middle of the side of the fixed frame, and the transmission rod is slidably inserted into the limiting groove.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This application discloses a surface grinder for machining precision workpieces. A bidirectional lead screw is rotatably mounted inside a fixed frame, and a transmission sprocket is connected to the bidirectional lead screw via a transmission rod. When a servo motor is running, it provides the corresponding rotational driving force to one side of the rotating rod. Combined with the meshing transmission action of the transmission chain ring on the transmission sprocket, the transmission sprockets and transmission rods located on both sides inside the connecting frame can rotate synchronously and in the same direction. Under the connecting transmission action of the transmission rod, the driving force required for the synchronous rotation of the two sets of bidirectional lead screws is provided, causing the two sets of bidirectional lead screws to rotate synchronously and in the same direction. Subsequently, combined with the rotational transmission action of the bidirectional lead screw on the transmission sleeve, the two sets of transmission sleeves can rotate synchronously towards or opposite each other. The push rod moves horizontally inside the fixed frame, which in turn drives the sliding plate and the fixed block to move horizontally towards or relative to each other at both ends of the fixed frame. Then, combined with the rotating shaft, the two ends of the push rod are hinged to the abutment plate and the side end of the fixed block respectively. The push rod can convert the horizontal movement force of the sliding plate and the fixed block into a horizontal pushing and pulling force on the abutment plate. This allows the two sets of abutment plates to move synchronously on both sides of the placement platform. While abutting and limiting the workpieces stacked on the surface of the placement platform, it pushes them on both sides and places them in the center under the grinding roller. This ensures that the grinding roller can move quickly and easily left and right to perform uniform grinding on the surface of the workpiece, reducing the difficulty of operator control and improving the grinding quality of the workpiece surface.

[0020] like Figure 1-3As shown, this utility model provides a technical solution: a surface grinder for processing precision workpieces, wherein a placement platform 13 is fixedly installed on the top surface of the support machine table 1, and a fixing plate 14 is fixedly installed on both ends of the side of the support machine table 1. A fixing frame 15 is fixedly installed on the middle of the side of the fixing plate 14, and a connecting frame 16 is fixedly installed between the sides of the two sets of fixing frames 15. Abutment plates 24 are slidably installed on both sides of the top of the placement platform 13.
[0021] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), rotating rods 28 are rotatably mounted on both sides of the inner side of the connecting frame 16 through bearings, and the top edge of the rotating rod 28 extends rotatably into the inner side of the fixed frame 15 through the bearings. The top edge of the rotating rod 28 is fixedly connected to the top edge of the bidirectional lead screw 2. A transmission sprocket 3 is fixedly sleeved on the outer side of each rotating rod 28. A transmission chain ring 31 is meshed between the outer edges of the two sets of transmission sprockets 3. Both the transmission sprockets 3 and the transmission chain ring 31 are rotatably disposed inside the connecting frame 16. A servo motor 32 is fixedly mounted on the outer side of the connecting frame 16, and the side of the transmission shaft of the servo motor 32 is fixedly connected to the top edge of the rotating rod 28 through a coupling.
[0022] After the workpiece to be ground is placed on the surface of the placement platform 13, the servo motor 32 is turned on by the external control switch, causing it to rotate and drive the rotating rod 28 on the side of the connecting frame 16 to rotate. Simultaneously, the transmission sprocket 3 sleeved on the outside of the rotating rod 28 rotates inside the connecting frame 16. Combined with the meshing transmission action of the transmission chain ring 31 on the transmission sprocket 3, the transmission sprockets 3 located on both sides inside the connecting frame 16 can be driven to rotate synchronously and in the same direction, providing the driving force required for the synchronous rotation of the two sets of rotating screws.
[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), both sides of the bidirectional lead screw 2 are threadedly connected to transmission sleeves 21. A transmission rod 22 is fixedly installed on the middle of the outer side of each transmission sleeve 21. A limiting groove 27 is opened at the middle of the side of the fixed frame 15, and the transmission rod 22 is slidably inserted into the limiting groove 27. Sliding plates 23 are slidably installed at both ends of the side of the fixed frame 15, and the top of the side of the transmission rod 22 is fixedly connected to the outer wall of the sliding plate 23. A fixing block 25 is fixedly installed at the middle of the outer side of each sliding plate 23. A push rod 26 is inclinedly hinged to the side of each fixing block 25 through a rotating shaft, and the top of the side of the push rod 26 is hinged to the outer wall of the abutment plate 24 through a rotating shaft.
[0024] After the two sets of rotating rods 28 rotate synchronously, under the connecting transmission action of the rotating rods 28, the two sets of rotating screws can be driven to rotate synchronously on both sides of the placement platform 13. Combined with the guiding and limiting action of the limiting groove 27 on the transmission rod 22, the transmission sleeve 21 can only move horizontally towards each other inside the fixed frame 15 synchronously with the rotation of the rotating screw, and will not rotate axially with the rotation of the rotating screw. During the synchronous movement of the transmission sleeve 21 towards each other, under the connecting transmission action of the transmission rod 22, the sliding plate 23 can be driven to move horizontally towards each other outside the fixed frame 15. This, combined with the rotating shaft, will... After the two ends of the push rod 26 are hinged to the abutment plate 24 and the side end of the fixing block 25 respectively, the push rod 26 can convert the horizontal moving force of the sliding plate 23 and the fixing block 25 into a horizontal pushing force on the abutment plate 24. This allows the two sets of abutment plates 24 to move synchronously on both sides of the placement platform 13. After the abutment plate 24 is attached to the outer wall of the workpiece, it abuts the workpiece, causing the workpiece to move horizontally on the surface of the placement platform 13. When the workpiece is pushed to the middle position on the surface of the placement platform 13, the outer wall of the abutment plate 24 can be attached to the outer wall of the workpiece to abut and limit its movement, thus completing the fixed placement of the workpiece.
[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), an electric slide rail is provided on the top side of the support platform 1. A drive frame 11 is connected to the top of the electric slide rail. A grinding roller 12 is slidably arranged on the side of the drive frame 11. A lifting mechanism and a drive mechanism are provided inside the drive frame 11, which can drive and adjust the rotation and vertical position of the grinding roller 12.
[0026] After the workpiece is fixed in place, the various driving components inside the drive frame 11 can be activated to drive the grinding roller 12 to rotate and move vertically and horizontally back and forth to perform grinding processing on the surface of the workpiece.
