Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a multi-station automatic wheel positioning cylindrical grinding machine. Background Technology

[0002] External cylindrical grinding machines are used to process the outer surfaces of workpieces formed by the generatrices of cylindrical, conical, or other shapes, as well as the end faces of shaft shoulders. They are the most widely used type of grinding machine, capable of processing various cylindrical and conical outer surfaces and end faces of shaft shoulders. Among all grinding machines, external cylindrical grinding machines are the most widely used type of machine tool.

[0003] Currently, most cylindrical grinding machines require manual clamping and fixing of the cylindrical shaft during machining. Operators must manually place the shaft onto the grinding machine's fixture and secure it using a clamping device to ensure stability during grinding. This not only increases the operator's workload but also, due to the limited precision and stability of manual clamping, may cause the shaft to shift position during grinding, thus affecting the grinding quality.

[0004] Furthermore, after grinding, manual unloading is required. Operators must wait for the grinding process to finish before manually removing the finished shaft from the grinding machine and placing it in the designated position. This makes automatic unloading difficult and results in low processing efficiency.

[0005] Therefore, a multi-station automatic wheel positioning external cylindrical grinding machine is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-station automatic positioning cylindrical grinding machine for grinding wheels in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A multi-station automatic wheel positioning cylindrical grinding machine includes a base plate. Four columns are fixedly connected to the top surface of the base plate. A spacing adjustment component is provided on the surface of each column. An automatic positioning component for fixing the workpiece is installed on the surface of the spacing adjustment component. A first electric push rod is fixedly installed on the top surface of the base plate. A support plate is provided above the first electric push rod. A placement groove is opened on the top surface of the support plate. An auxiliary feeding component for controlling the tilt of the support plate is installed at the telescopic end of the first electric push rod. A grinding component is installed on the rear side of the top surface of the base plate.

[0009] Furthermore, the spacing adjustment assembly includes a first motor, which is fixedly mounted on the surface of the right front column. The output end of the first motor is fixedly connected to a first double-ended screw, which is rotatably connected to the surfaces of the two front columns. The surfaces of the two rear columns are fixedly connected to sliding columns, and the surfaces of the sliding columns are slidably connected to two mounting plates, which are threadedly connected to the first double-ended screw.

[0010] Furthermore, the automatic positioning component includes a second motor, which is fixedly mounted on the surface of the left mounting plate. The output end of the second motor is fixedly connected to a first rotating shaft, which is rotatably connected to the surface of the left mounting plate. A second rotating shaft is rotatably connected to the surface of the right mounting plate. Both the ends of the second and first rotating shafts are fixedly connected to mounting shells. A third motor is fixedly mounted on the inner wall of the mounting shell. The output end of the third motor is fixedly connected to a second double-ended screw. Two connecting rods are threaded onto the surface of the second double-ended screw, and the connecting rods are movably inserted into the mounting shell. A clamping block is fixedly connected to the end of each connecting rod.

[0011] Furthermore, an anti-slip pad is fixedly connected to the surface of the clamping block.

[0012] Furthermore, the auxiliary feeding assembly includes a support frame, and the support frame is fixedly connected to the telescopic end of the first electric push rod. One end of the support frame is attached to the bottom of the bearing plate, and the other end of the support frame is hinged to the bearing plate. A second electric push rod is rotatably mounted on the surface of the support frame, and the telescopic end of the second electric push rod is rotatably connected to the bottom surface of the bearing plate.

[0013] Furthermore, the grinding assembly includes a fixed frame, which is fixedly connected to the top surface of the base plate. A third electric push rod is fixedly mounted on the surface of the fixed frame. The telescopic end of the third electric push rod is fixedly connected to a mounting frame, and the mounting frame is slidably connected to the surface of the fixed frame. An electric cylindrical grinding wheel is mounted on the surface of the mounting frame.

[0014] The beneficial effects of this utility model are as follows:

[0015] The user places the cylindrical workpiece to be ground into the placement slot. Then, the first electric push rod drives the auxiliary unloading component and the support plate to rise, bringing the workpiece to the height of the automatic positioning component. The spacing adjustment component then controls the movement of the automatic positioning component, bringing it into contact with the workpiece and fixing it in place. The first electric push rod then controls the auxiliary unloading component and the support plate to descend, no longer contacting the workpiece. The grinding component then operates to grind the workpiece. After grinding, the first electric push rod controls the support plate to rise again, releasing the automatic positioning component from its position, allowing the workpiece to fall back into the placement slot. The auxiliary unloading component then automatically unloads the workpiece. This system facilitates automatic positioning of cylindrical workpieces, eliminating the need for repeated manual adjustments, making operation more convenient. Furthermore, the automatic unloading after grinding further improves processing efficiency. Attached Figure Description

[0026] like Figures 1 to 4As shown, a multi-station automatic wheel positioning cylindrical grinding machine includes a base plate 1. Four columns 2 are fixedly connected to the top surface of the base plate 1. A spacing adjustment component 3 is provided on the surface of the columns 2. An automatic positioning component 4 for fixing the workpiece is installed on the surface of the spacing adjustment component 3. A first electric push rod 5 is fixedly installed on the top surface of the base plate 1. A bearing plate 6 is provided above the first electric push rod 5. A placement groove 8 is opened on the top surface of the bearing plate 6. An auxiliary feeding component 7 for controlling the tilt of the bearing plate 6 is installed at the telescopic end of the first electric push rod 5. A grinding component 9 is installed on the rear side of the top surface of the base plate 1. More specifically, the user places the cylindrical workpiece to be ground into the placement groove 8. Then, the first electric push rod 5 drives the auxiliary unloading component 7 and the support plate 6 to rise, bringing the workpiece to the height of the automatic positioning component 4. The spacing adjustment component 3 then operates to control the movement of the automatic positioning component 4, making it contact with the workpiece and fixing it in place. The first electric push rod 5 then controls the auxiliary unloading component 7 and the support plate 6 to descend, no longer contacting the workpiece. The grinding component 9 then operates to grind the workpiece. After grinding, the first electric push rod 5 controls the support plate 6 to rise, releasing the automatic positioning component 4 from its position, allowing the workpiece to fall back into the placement groove 8. The auxiliary unloading component 7 then operates to automatically unload the workpiece.

[0027] The spacing adjustment component 3 includes a first motor 301, which is fixedly mounted on the surface of the right front column 2. The output end of the first motor 301 is fixedly connected to a first double-ended screw 302, which is rotatably connected to the surfaces of the two front columns 2. Sliding columns 304 are fixedly connected to the surfaces of the two rear columns 2. Two mounting plates 303 are slidably connected to the surfaces of the sliding columns 304, and the mounting plates 303 are threadedly connected to the first double-ended screw 302. It should be noted that by operating the first motor 301, the first double-ended screw 302 is driven to rotate. Under the action of the thread, the mounting plates 303 can slide along the surface of the sliding columns 304, thereby controlling the movement of the automatic positioning component 4 and its contact with the end of the cylindrical workpiece, thus facilitating subsequent workpiece positioning.

[0028] The automatic positioning component 4 includes a second motor 401, which is fixedly mounted on the surface of the left mounting plate 303. The output end of the second motor 401 is fixedly connected to a first rotating shaft 402, and the first rotating shaft 402 is rotatably connected to the surface of the left mounting plate 303. The surface of the right mounting plate 303 is rotatably connected to a second rotating shaft 409. The ends of the second rotating shaft 409 and the first rotating shaft 402 are both fixedly connected to a mounting shell 403. A third motor 404 is fixedly mounted on the inner wall of the mounting shell 403. The output end of the third motor 404 is fixedly connected to a second double-ended screw 405. The surface of the second double-ended screw 405 is threaded with two connecting rods 406, and the connecting rods 406 are movably inserted into the mounting shell 403. The ends of the connecting rods 406 are fixedly connected to a clamping block 407. More specifically, by moving the mounting shells 403 on both sides closer together through the mounting plate 303, the two ends of the cylindrical workpiece can be clamped and fixed. Then, the second double-ended screw 405 is driven to rotate by the third motor 404, and the connecting rod 406 is moved under the action of the thread, which controls the movement of the clamping block 407 and presses against the surface of the workpiece. The clamping block 407 is used to strengthen the limiting of the workpiece. During the processing, the first rotating shaft 402 is driven to rotate by the second motor 401, which drives the mounting shell 403 and the second rotating shaft 409 to rotate, thereby driving the workpiece to rotate and perform full grinding on the workpiece.

[0029] An anti-slip pad 408 is fixedly connected to the surface of the clamping block 407. It should be noted that by setting the anti-slip pad 408, the friction between the anti-slip pad and the cylindrical workpiece is increased, making the clamping of the corresponding workpiece more stable.

[0030] The auxiliary unloading assembly 7 includes a support frame 701, which is fixedly connected to the telescopic end of the first electric push rod 5. One end of the support frame 701 is attached to the bottom of the support plate 6, and the other end of the support frame 701 is hinged to the support plate 6. A second electric push rod 702 is rotatably mounted on the surface of the support frame 701, and the telescopic end of the second electric push rod 702 is rotatably connected to the bottom surface of the support plate 6. More specifically, by operating the second electric push rod 702, its telescopic end is extended, thereby pushing the right side of the support plate 6 upward, causing the support plate 6 to tilt as a whole. The cylindrical workpiece on the surface of the support plate 6 will slide to the left under the action of gravity, thereby realizing the unloading of the workpiece. In specific implementation, a container for holding the workpiece can also be set below the support plate 6.

[0031] The grinding assembly 9 includes a fixed frame 901, which is fixedly connected to the top surface of the base plate 1. A third electric push rod 902 is fixedly mounted on the surface of the fixed frame 901. A mounting frame 903 is fixedly connected to the telescopic end of the third electric push rod 902, and the mounting frame 903 is slidably connected to the surface of the fixed frame 901. An electric cylindrical grinding wheel 904 is mounted on the surface of the mounting frame 903. It should be noted that the fixed frame 901 drives the mounting frame 903 to move downwards, thereby causing the electric cylindrical grinding wheel 904 to descend. The electric cylindrical grinding wheel 904 then contacts the surface of the cylindrical workpiece, thereby grinding the workpiece surface.

[0032] In summary: The user places the cylindrical workpiece to be ground into the placement groove 8. Then, the first electric push rod 5 drives the auxiliary unloading component 7 and the support plate 6 to rise, bringing the workpiece to the height of the automatic positioning component 4. The spacing adjustment component 3 then controls the movement of the automatic positioning component 4, bringing it into contact with the workpiece and fixing it in place. The first electric push rod 5 then controls the auxiliary unloading component 7 and the support plate 6 to descend, no longer contacting the workpiece. The grinding component 9 then operates to grind the workpiece. After grinding, the first electric push rod 5 controls the support plate 6 to rise, releasing the automatic positioning component 4 from its position, allowing the workpiece to fall back into the placement groove 8. The auxiliary unloading component 7 then automatically unloads the workpiece. This system facilitates automatic positioning of cylindrical workpieces, eliminating the need for repeated manual adjustments and making operation more convenient. Furthermore, the automatic unloading after grinding further improves processing efficiency.
