Description

Technical Field

[0001] This application relates to the technical field of grinding, and in particular to a conical grinding and burr removal device. Background Technology

[0002] After machining, the tapered hole inside the workpiece needs to be precision machined. Specifically, this involves grinding the tapered surface of the hole and removing burrs from the keyway on the tapered surface. In related technologies, the workpiece tapered surface grinding and burr removal require fixing a reamer to a reamer holder, manually placing the workpiece on the reamer, inserting the reamer into the tapered hole inside the workpiece, holding the workpiece still, and manually rotating the reamer to grind the tapered surface and remove burrs from the workpiece's internal tapered hole.

[0003] However, when the workpiece size is small and mass production is required, manual operation is inconvenient and inefficient, and requires a high level of skill from the operators. It is not easy to effectively grind the conical surface and remove the burrs from the conical keyway, which does not meet the requirements of product quality characteristics or production efficiency. Utility Model Content

[0004] To meet the efficiency requirements of mass production of smaller workpieces and improve the efficiency of grinding conical surfaces and removing burrs from conical keyways, this application provides a conical surface grinding and burr removal device.

[0005] The conical surface grinding and burr removal device provided in this application adopts the following technical solution:

[0006] A conical surface grinding and burr removal device includes an electrical control cabinet, a platform, a rotating mechanism, a lifting mechanism, and a middle plate;

[0007] The electrical control cabinet is equipped with a control switch, and the platform is fixedly installed on the top surface of the electrical control cabinet;

[0008] The rotating mechanism includes a reamer holder and a reamer body. The reamer holder is fixedly mounted on the platform, and the reamer body is fixed on the reamer holder and adapted to the tapered hole in the workpiece. The rotation speed and time of the reamer body are controlled by a program in the electrical control cabinet.

[0009] The middle plate is raised and lowered on the platform by a lifting mechanism. The middle plate has a machining hole, and a positioning cylinder for placing the workpiece is fixedly installed at the machining hole. The positioning cylinder is located directly above the reamer body.

[0010] The lifting mechanism includes a pressure block, which is located above the positioning cylinder and can press the workpiece against the positioning cylinder.

[0011] By adopting the above technical solution, during operation, simply place the workpiece on the positioning cylinder, toggle the control switch, and the pressure block will press the workpiece firmly against the positioning cylinder. The workpiece descends with the middle plate until the reamer penetrates into the workpiece and contacts it, thereby grinding the conical surface and removing burrs. After grinding, the workpiece and the middle plate rise back to their original position and retract from the pressure block, and finally the workpiece can be removed. This effectively grinds the conical surface of the workpiece and removes burrs from the keyway, improving product stability, reducing the operator's workload, and increasing production efficiency, thus helping to meet the efficiency requirements of mass production of smaller workpieces.

[0012] Optionally, the lifting mechanism further includes a cylinder, a guide shaft, and an elastic element; a top plate is provided above the middle plate; the guide shaft is arranged between the top plate and the middle plate, one end of the guide shaft is fixedly connected to the top plate, and the other end of the guide shaft passes through the middle plate; the elastic element is arranged between the middle plate and the platform.

[0013] The cylinder is fixedly mounted on the top plate, and the piston rod of the cylinder is connected to the pressure block.

[0014] By adopting the above technical solution, when the pressure block needs to press the workpiece against the positioning cylinder, the cylinder is activated. The piston rod of the cylinder extends, driving the pressure block to descend until it contacts the workpiece, thus achieving the pressing and fixing of the workpiece. Then, the piston rod of the cylinder continues to extend, the elastic element compresses, and the pressure block pushes the workpiece downwards until the reamer body extends into the workpiece to grind the conical surface and remove burrs from the keyway. The guide shaft acts as a guide, helping to improve the stability of the middle plate lifting, and thus helping to align the workpiece with the reamer body.

[0015] Optionally, the elastic element is a spring, with its two ends connected to the middle plate and the platform, respectively.

[0016] Optionally, linear bearings are fixedly installed on both the middle plate and the platform, and the two ends of the spring are respectively connected to the middle plate and the platform through the linear bearings; the guide shaft passes through the spring and the linear bearing located on the middle plate, and the bottom end of the guide shaft is connected to the bearing located on the platform.

[0017] By adopting the above technical solutions, linear bearings help reduce friction and improve motion accuracy, while bearing axial and radial loads.

[0018] Optionally, the piston rod of the cylinder is connected to the pressure block via a universal joint.

[0019] Optionally, a mounting ring is fixedly connected to the bottom end of the linear bearing;

[0020] For the middle plate, the linear bearing passes through the middle plate, and the mounting ring is located below the middle plate and fixedly connected to the middle plate;

[0021] For the platform, the mounting ring is fixedly connected to the top surface of the platform.

[0022] By adopting the above technical solution, the installation of linear bearings is facilitated.

[0023] Optionally, a limit rod is fixedly installed on the platform, with the end of the limit rod away from the platform passing through the middle plate.

[0024] By adopting the above technical solutions, the stability of the middle plate lifting can be further improved, thereby further improving the alignment between the workpiece and the reamer body.

[0025] In summary, this application includes at least the following beneficial technical effects:

[0026] During operation, simply place the workpiece on the positioning cylinder, turn on the control switch, and the pressure block will hold the workpiece firmly against the positioning cylinder. The workpiece descends with the middle plate until the reamer penetrates and contacts the workpiece, thus grinding the conical surface and removing burrs. After grinding, the workpiece and the middle plate rise back to their original position and retract from the pressure block. Finally, the workpiece can be removed. This method effectively grinds the conical surface of the workpiece and removes burrs from the keyway, improving product stability while reducing the operator's workload and increasing production efficiency, thus helping to meet the efficiency requirements of mass production of smaller workpieces.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-5This application will be described in further detail.

[0034] This application discloses a device for conical surface grinding and burr removal. (Refer to...) Figure 1-5 The conical surface grinding and burr removal device includes an electrical control cabinet 15, a platform 16, a rotating mechanism, a lifting mechanism, and a middle plate 5. The electrical control cabinet 15 is equipped with a control switch 14, and the platform 16 is fixedly mounted on the top surface of the electrical control cabinet 15. The rotating mechanism includes a reamer holder 13 and a reamer body 12. The reamer holder 13 is fixedly mounted on the platform 16, and the reamer body 12 is fixed on the reamer holder 13 and matches the conical hole in the workpiece 9. The rotation speed and time of the reamer body 12 are controlled by a program in the electrical control cabinet 15. The middle plate 5 is raised and lowered on the platform 16 via the lifting mechanism. A machining hole is provided on the middle plate 5, and a positioning cylinder 10 for placing the workpiece 9 is fixedly mounted at the machining hole. The positioning cylinder 10 is located directly above the reamer body 12. The lifting mechanism includes a pressure block 8, which is located above the positioning cylinder 10 and can press the workpiece 9 against the positioning cylinder 10.

[0035] During operation, simply place the workpiece 9 on the positioning cylinder 10, activate the control switch 14, and the pressure block 8 will press the workpiece 9 firmly against the positioning cylinder 10. The workpiece 9 will descend with the middle plate 5 until the reamer body 12 extends into and contacts the workpiece 9, thus grinding the conical surface and removing burrs. After grinding, the workpiece 9 and the middle plate 5 rise back to their original positions and retract from the pressure block 8. Finally, the workpiece 9 can be removed. This method effectively grinds the conical surface of the workpiece 9 and removes burrs from the keyway, improving product stability, reducing operator workload, and increasing production efficiency. It also helps meet the efficiency requirements for batch production of smaller workpieces 9.

[0036] Reference Figure 1-2 and Figure 4 The lifting mechanism also includes a cylinder 1, a guide shaft 3, and an elastic element. A top plate 2 is provided above the middle plate 5. The guide shaft 3 is arranged between the top plate 2 and the middle plate 5, with one end of the guide shaft 3 fixedly connected to the top plate 2 and the other end of the guide shaft 3 passing through the middle plate 5. The elastic element is arranged between the middle plate 5 and the platform 16. The cylinder 1 is fixedly mounted on the top plate 2, and the piston rod of the cylinder 1 is connected to the pressure block 8.

[0037] When the pressure block 8 needs to press the workpiece 9 against the positioning cylinder 10, the cylinder 1 is activated. The piston rod of the cylinder 1 extends, driving the pressure block 8 to descend until it contacts the workpiece 9, thus securing the workpiece 9. Then, the piston rod of the cylinder 1 continues to extend, compressing the elastic element. The pressure block 8 pushes the workpiece 9 downwards until the reamer body 12 extends into the workpiece 9 to grind the conical surface and remove burrs from the keyway. The guide shaft 3 acts as a guide, helping to improve the stability of the lifting and lowering of the middle plate 5, and thus helping to align the workpiece 9 with the reamer body 12.

[0038] Reference Figure 1 The elastic element is a spring 6, with its two ends connected to the middle plate 5 and the platform 16, respectively. Linear bearings 4 are fixedly mounted on both the middle plate 5 and the platform 16, and the two ends of the spring 6 are connected to the middle plate 5 and the platform 16 respectively via the linear bearings 4. A guide shaft 3 passes through the spring 6 and the linear bearing 4 located on the middle plate 5, with its bottom end connected to a bearing located on the platform 16. The linear bearing 4 helps reduce friction and improve motion accuracy, while also bearing axial and radial loads.

[0039] Reference Figure 1 The piston rod of cylinder 1 is connected to pressure block 8 via universal joint 7, and mounting ring 41 is fixedly connected to the bottom end of linear bearing 4. For middle plate 5, linear bearing 4 passes through middle plate 5, and mounting ring 41 is located below middle plate 5 and fixedly connected to middle plate 5. For platform 16, mounting ring 41 is fixedly connected to the top surface of platform 16 to facilitate the installation of linear bearing 4. Limiting rod 11 is fixedly installed on platform 16, and the end of limiting rod 11 away from platform 16 passes through middle plate 5, which helps to further improve the stability of middle plate 5 lifting and lowering, thereby further improving the alignment of workpiece 9 and reamer body 12.
