Description

Technical Field

[0001] The utility model relates to the technical field of metal parts processing devices, in particular to a magnetic suction type annular parts fixing processing device. Background Art

[0002] The processing of annular parts usually includes forming and finishing steps. In the finishing step, especially when the outer peripheral surface of the annular part has a high flatness requirement, it is usually completed with the help of a machine tool and a grinding disc. That is, two discs with a radius smaller than the radius of the annular part are used to clamp the annular part and clamp it to the machine tool. The annular part is rotated by the rotation of the machine tool, and the outer peripheral surface is polished with the help of a grinding disc. This operation method has a low polishing efficiency for the outer peripheral surface of the annular part, because the processing of a single annular part requires manual clamping once, and is not suitable for the outer peripheral polishing of batch annular parts. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a magnetic suction type annular parts fixing and processing device.

[0004] The technical solution of this utility model is as follows:

[0005] A magnetic annular part fixing and processing device comprises a first driving machine and a second driving machine arranged in parallel, wherein the output shafts of the first driving machine and the second driving machine are respectively provided with a grinding disc and a fixing mechanism, and the annular part can be fixed on the fixing mechanism and the outer peripheral surface can be ground by the grinding disc.

[0006] As the core technical concept of the present invention, the fixing mechanism includes a connecting block which is transmission-connected to the output shaft of the second driving machine on one side, and a magnetic block is also provided on the side of the connecting block away from the second driving machine. The fixing mechanism also includes a positioning cylinder which is interconnected at both ends, and the axis of the positioning cylinder coincides with the axis of the output shaft of the second driving machine, and one end is connected to the side of the magnetic block away from the connecting block. The annular part to be processed can be adsorbed on the end of the positioning cylinder away from the magnetic block under the magnetic force of the magnetic block, and driven to rotate by the second driving machine, and the grinding work of the outer peripheral surface of the annular part is completed in cooperation with the grinding disk. The setting of the positioning cylinder ensures that the annular part can be more stably fitted with the positioning cylinder under the action of the magnetic block, so that the fixing work of the annular part is simpler and the polishing efficiency is significantly improved. At the same time, the outer diameter of the end of the positioning cylinder away from the magnetic block is not larger than the outer diameter of the annular part to be processed, thereby ensuring that the grinding work of the outer peripheral surface of the annular part can be completed more smoothly by the grinding disk.

[0007] As described above, a magnetic annular part fixing processing device is, as a preferred embodiment, an annular clamping plate is also provided on the outer ring of the end of the positioning cylinder away from the magnetic suction block. The annular part can be tightly attached to the outer side of the clamping plate under the magnetic force of the magnetic suction block. By increasing the contact area with the annular part, the magnetic fixing work of the annular part is made more secure while ensuring that the adsorption effect of the magnetic suction block on the annular part is not affected.

[0008] In order to further enable the annular part to be smoothly ground to a desired size under the action of the grinding disc, the outer diameter of the abutting piece is set to be smaller than the outer diameter of the annular part to be processed.

[0009] As described above, a magnetic annular part fixing processing device is used. In order to prevent the setting of the magnetic block from causing vibration when the output shaft of the second driving machine rotates and ensure the fixing effect of the annular part, the magnetic block adopts a columnar structure whose axis coincides with the axis of the output shaft of the second driving machine.

[0010] In order to prevent the magnetic block from interfering with the grinding work of the grinding disc, the magnetic block is configured to have an outer diameter smaller than the outer diameter of the abutting piece.

[0011] In order to prevent the setting of the connection block from causing vibration when the output shaft of the second driving machine rotates and further ensure the fixing effect of the annular part, the connection block also adopts a columnar structure whose axis coincides with the axis of the output shaft of the second driving machine.

[0012] In the magnetic annular part fixing processing device as described above, the grinding disc is arranged vertically. To ensure that the outer peripheral surface of the annular part can be ground more thoroughly, the plane where the outer side surface of the clamping plate is located is not located on the side of the plane where the inner side surface of the grinding disc is located close to the first driving machine. At the same time, the plane where the outer side surface of the clamping plate is located is located on the side of the plane where the outer side surface of the grinding disc is located close to the first driving machine.

[0013] As a preferred embodiment, the output shaft axes of the first driving machine and the second driving machine are located in the same horizontal plane, thereby reducing the impact of the rotation of the grinding disc on the annular part and ensuring the fixation stability of the annular part.

[0014] In order to further ensure that the grinding work can proceed smoothly, prevent the ring parts from being damaged during grinding, and ensure the grinding quality, the processing device (the above-mentioned magnetic suction type ring parts fixing processing device) also includes a water spraying mechanism that can spray water to the grinding position.

[0015] The beneficial effects of the utility model are as follows: the utility model is a magnetic suction type annular part fixing processing device. The annular part to be processed can be adsorbed on the end of the positioning cylinder away from the magnetic suction block under the magnetic force of the magnetic suction block, and driven to rotate by the second driving machine, and cooperate with the grinding disc to complete the grinding of the outer peripheral surface of the annular part. The setting of the positioning cylinder ensures that the annular part can be more stably fitted with the positioning cylinder under the action of the magnetic suction block, making the fixing work of the annular part simpler and significantly improving the polishing efficiency. At the same time, the outer diameter of the end of the positioning cylinder away from the magnetic suction block is not greater than the setting of the outer diameter of the annular part to be processed, ensuring that the grinding work of the outer peripheral surface of the annular part can be completed more smoothly through the grinding disc.

[0023] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0024] Example

[0025] This embodiment provides a magnetic suction type annular parts fixing and processing device, see Figure 1, including a base plate 1 and a first driving machine 2 and a second driving machine 3 arranged in parallel thereon, wherein a grinding disc 4 and a fixing mechanism 6 are respectively provided on the output shafts of the first driving machine 2 and the second driving machine 3, and the annular part can be fixed on the fixing mechanism 6 and the outer peripheral surface can be ground by the grinding disc 4. The structure of the processing device (the above-mentioned magnetic suction type annular part fixing processing device) is described in detail below.

[0026] In the present embodiment, the first driving machine 2 is arranged horizontally, and the grinding disc 4 is vertically arranged on the output shaft of the first driving machine 2. Since the grinding disc 4 usually has a larger specification, in order to ensure that the rotation of the grinding disc 4 is more stable, the processing device also includes a centering frame 5. The centering frame 5 is a steel plate strip with a C-shaped structure. Both ends of the steel plate strip are fixed to the first driving machine 2. The grinding disc 4 is located inside the centering frame 5, and the output shaft of the first driving machine 2 passes through the grinding disc 4 and is rotatably connected to the centering frame 5.

[0027] In this embodiment, combined with Figure 2 The second driving machine 3 is arranged horizontally. As the core technical concept of the present utility model, the fixing mechanism 6 includes a connecting block 61 which is connected to the output shaft of the second driving machine 3 on one side. A magnetic block 62 is provided on the side of the connecting block 61 away from the second driving machine 3. A positioning piece 63 is provided on the side of the magnetic block 62 away from the connecting block 61. The annular part can be fixed on the outside of the positioning piece 63 under the magnetic force of the magnetic suction cup, and cooperate with the grinding disc 4 to complete the grinding work of the annular part.

[0028] On the basis of the above structure, in order to prevent the setting of the connecting block 61 from causing vibration when the output shaft of the second driving machine 3 rotates and to ensure the adsorption and fixing effect between the annular part and the positioning member 63, the connecting block 61 adopts a columnar structure whose axis coincides with the axis of the output shaft of the second driving machine 3.

[0029] Furthermore, in order to prevent the setting of the magnetic block 62 from causing vibration when the output shaft of the second driving machine 3 rotates and to ensure the adsorption and fixing effect between the annular part and the positioning member 63, the magnetic block 62 adopts a columnar structure whose axis coincides with the axis of the output shaft of the second driving machine 3.

[0030] Specifically, one end of the connection block 61 is keyed to the output shaft of the second driving machine 3, and a socket is provided in the middle of the other end. The magnetic block 62 is inserted into the socket and fixed by a screw or a fixing pin.

[0031] As for the structure of the positioning member 63, Figure 3It includes a positioning cylinder 632 with two ends connected to each other, the axis of the positioning cylinder 632 coincides with the axis of the output shaft of the second driving machine 3, and one end is connected to the side of the magnetic block 62 away from the connecting block 61. The annular part to be processed can be adsorbed on the end of the positioning cylinder 632 away from the magnetic block 62 under the magnetic force of the magnetic block 62, and driven to rotate by the second driving machine 3, and cooperate with the grinding disc 4 to complete the grinding of the outer peripheral surface of the annular part. The setting of the two ends of the positioning cylinder 632 being connected reduces the influence of the magnetic force of the magnetic block 62, and ensures that the annular part can be more stably fitted with the positioning cylinder 632 under the action of the magnetic block 62, making the fixing work of the annular part simpler and significantly improving the polishing efficiency.

[0032] It should be noted that the outer diameter of the end of the positioning cylinder 632 away from the magnetic block 62 is not greater than the outer diameter of the annular part to be processed, so as to ensure that the grinding work of the outer peripheral surface of the annular part can be completed more smoothly by the grinding disc 4.

[0033] As for the fixing method of the positioning member 63, a columnar connecting tube 631 is provided at one end of the positioning tube 632 close to the magnetic block 62. The connecting tube 631 is sleeved on the outer ring of the end of the magnetic block 62 away from the connecting block 61 and fixed by screws or fixing pins to complete the fixing work of the positioning tube 632.

[0034] As a preferred embodiment of the utility model, the positioning member 63 also includes an annular clamping piece 633 arranged on the outer circle of the positioning tube 632 away from the magnetic block 62. The inner circle of the clamping piece is fixed to the outer circle of the positioning tube 632. The annular part can be tightly attached to the outer side of the clamping piece under the magnetic force of the magnetic block 62. By increasing the contact area with the annular part, the magnetic fixing work of the annular part is made more secure while ensuring that the adsorption effect of the magnetic block 62 on the annular part is not affected.

[0035] In order to ensure the structural strength of the positioning member 63 and further ensure the stability of the adsorption and fixation of the annular part, the positioning member 63 is formed by one-piece processing.

[0036] In order to further enable the annular part to be smoothly ground to a desired size under the action of the grinding disc 4, the outer diameter of the abutting piece 633 is set to be smaller than the outer diameter of the annular part to be processed.

[0037] In order to prevent the magnetic block 62 from interfering with the grinding work of the grinding disc 4 , the magnetic block 62 is configured to have an outer diameter smaller than the outer diameter of the abutting piece 633 .

[0038] More preferably, the outer diameter of the positioning cylinder 632 at the end away from the magnetic block 62 is larger than the outer diameter of the end close to the magnetic block 62, so that the positioning cylinder 632 is trumpet-shaped as a whole, and the cylinder wall cross-section of the positioning cylinder 632 is an arc-shaped structure with an opening facing inward, which further reduces the risk of interference between the grinding disk 4 and the magnetic block 62.

[0039] In this embodiment, in order to ensure that the grinding work of the outer peripheral surface of the annular part can be more thorough, the plane where the outer side surface of the clamping plate 633 is located is not located on the side of the plane where the inner side surface of the grinding disk 4 is located close to the first driving machine 2. At the same time, the plane where the outer side surface of the clamping plate 633 is located is located on the side of the plane where the outer side surface of the grinding disk 4 is located close to the first driving machine 2.

[0040] As a preferred embodiment, the output shaft axes of the first driving machine 2 and the second driving machine 3 are located in the same horizontal plane, so as to reduce the influence of the rotation of the grinding disc 4 on the annular parts and ensure the fixing stability of the annular parts.

[0041] To further ensure that the grinding work can proceed smoothly, prevent the annular parts from being damaged during grinding, and ensure the grinding quality, the processing device also includes a water spray mechanism (not shown) that can spray water toward the grinding position (the side of the grinding disc 4 close to the positioning member 63).
