Description

Technical Field

[0001] This application relates to the field of machine tool processing, and particularly to a multi-station fixed-angle grinding mechanism. Background Art

[0002] "Grinding" is a machining method that uses grinding tools such as grinding wheels, abrasive belts, and sandpapers to cut the surface of a workpiece to remove a small amount of material and achieve the required shape, size, and surface roughness. Grinding is usually used for finish machining and surface treatment, which can significantly improve the accuracy and surface quality of the workpiece.

[0003] Currently, the general method for grinding aviation glass is to install a grinding wheel on a numerically controlled five-axis machining device and then operate the numerically controlled five-axis machining device to grind the glass.

[0034] The present application provides a multi-station fixed-angle grinding mechanism.

[0035] Embodiment 1:

[0036] Refer to Figure 1 , a multi-station fixed-angle grinding mechanism includes: a ram 1 and a grinding member 2. In the actual application of the ram 1 in the embodiment of the present application, the ram 1 is slidably mounted on a cross beam, and the cross beam is slidably mounted on a base (the cross beam and the base are not shown in the figure). A rotating shaft 11 is vertically rotatably mounted on the ram 1; a driving motor 12 is mounted on the ram 1, and the output shaft of the driving motor 12 is transmitted with the rotating shaft 11 through a transmission belt 13. During processing, the driving motor 12 is started, and through the arrangement of the transmission belt 13, the rotating shaft 11 can rotate.

[0037] Refer to Figure 1 , a fixing pipe 3 is fixedly arranged at the bottom of the ram 1 through bolts, a connecting seat 4 is mounted at the bottom of the fixing pipe 3 through bolts, and a connecting frame 5 is fixedly mounted at the bottom end of the connecting seat 4; the grinding member 2 is mounted on the connecting frame 5. In this embodiment, the longitudinal section of the connecting frame 5 is a right trapezoid, and the included angle between the inclined surface of the connecting frame 5 and the rotating shaft 11 is 30°; the grinding member 2 is mounted on the inclined surface of the connecting frame 5. By using the connecting frame 5 to mount the grinding member 2 on the ram 1, a horizontal 30° grinding operation can be performed on the glass; and the connection nodes of the grinding mechanism are reduced, thereby reducing the wear between the nodes. At the same time, different-shaped connecting frames 5 can be replaced to achieve multi-station processing.

[0038] In the embodiment of the present application, the grinding member 2 includes: a motor and a grinding wheel. The grinding wheel is fixedly mounted on the output shaft of the motor. By starting the motor to drive the grinding wheel to rotate, the glass can be ground.

[0039] Refer to Figure 2 , however, in the embodiment of the present application, when vertical grinding of the glass is required, the grinding wheel only needs to be mounted on the rotating shaft 11, and there is no need for the connecting frame 5 and the motor in the grinding member 2.

[0040] The working principle of Embodiment 1 is specifically as follows: By using the connecting frame 5 to mount the grinding member 2 on the ram 1, a horizontal 30° grinding operation can be performed on the glass; and the connection nodes of the grinding mechanism are reduced, thereby reducing the wear between the nodes. At the same time, different-shaped connecting frames 5 can be replaced to achieve multi-station processing.

[0041] Embodiment 2:

[0042] Refer to Figure 3The difference between this embodiment and the first embodiment is that the longitudinal section of the connecting frame 5 is rectangular, the grinding piece 2 is mounted on the bottom wall of the connecting frame 5 by bolts, and the grinding piece 2 is mounted on the slide 1 by using the connecting frame 5, so that the glass can be ground horizontally at right angles.

[0043] The working principle of the second embodiment is as follows: the grinding piece 2 is mounted on the ram 1 by using the connecting frame 5, so that the glass can be ground horizontally at right angles.

[0044] Embodiment three:

[0045] See also Figure 4 and Figure 5 The difference between this embodiment and the first embodiment is that a connecting assembly is provided between the connecting seat 4 and the fixing pipe 3, and the connecting assembly can conveniently and quickly install and disassemble the connecting seat 4, so that the connecting frame 5 can be quickly replaced.

[0046] See also Figure 6 The connecting assembly includes: a connecting part 6, a connecting part 7 and a pulling part 8.

[0047] See also Figure 6 The connecting part 6 includes: a connecting rod 61, a first magnetic block 62 and a second magnetic block 63.

One end of the connecting rod 61 is fixedly connected to the connecting seat 4, and the other end is arranged in the connecting hole 31 and fixedly connected to the second magnetic block 63; the first magnetic block 62 and the second magnetic block 63 are magnetically attracted to each other. When installing, the connecting rod 61 is inserted into the connecting hole 31 until the first magnetic block 62 and the second magnetic block 63 are magnetically attracted to each other, thereby completing the preliminary connection between the connecting seat 4 and the fixed tube 3.

[0048] See also Figure 6 The connecting part 7 includes: a connecting rod 71 and a connecting spring 72. The connecting rod 61 is provided with a receiving cavity 611, and the inner wall of the receiving cavity 611 is provided with a receiving hole 612; the inner wall of the connecting hole 31 is provided with a connecting hole 32. One end of the connecting rod 71 is arranged in the receiving hole 612, and the other end is arranged in the connecting hole 32. The connecting rod 71 can lock the connecting rod 61, thereby further completing the connection between the connecting seat 4 and the fixing pipe 3, and improving the connection stability between the connecting seat 4 and the fixing pipe 3.

[0049] See also Figure 6 The connecting spring 72 is sleeved on one end of the connecting rod 71 located in the accommodating hole 612, and one end of the connecting spring 72 is fixed to the connecting rod 71, and the other end is fixed to the bottom of the accommodating hole 612. The connecting spring 72 is used to pull the connecting rod 71 back into the accommodating hole 612, thereby facilitating the unlocking.

[0050] See also Figure 6, the pulling part 8 includes: a pull rod 81 and a pulling spring 82. A pulling hole 41 is formed on the side of the connecting seat 4 away from the fixed pipe 3. One end of the pull rod 81 is arranged in the accommodating cavity 611 and abuts against the connecting rod 71, and the other end penetrates into the pulling hole 41. An insertion hole 811 for inserting the connecting rod 71 is formed on one end of the pull rod 81 located in the accommodating cavity 611 and facing the connecting rod 71.

The pulling spring 82 is used to push the pull rod 81 to stably insert into the accommodating cavity 611. During disassembly, pull down the pull rod 81; until the insertion hole 811 is coaxial with the connecting rod 71, the connecting rod 71 will automatically insert into the insertion hole 811 through the reset of the connecting spring 72, so as to disengage from the connecting hole 32 and release the locking.

[0052] See Figure 6 , a guiding surface 711 is arranged on one end of the connecting rod 71 close to the pull rod 81 and facing the connecting seat 4, and when the connecting rod 71 is inserted into the insertion hole 811, the end of the guiding surface 711 away from the pull rod 81 is lower than the opening of the insertion hole 811. When the pull rod 81 is further completely inserted into the accommodating cavity 611, through the setting of the guiding surface 711, the connecting rod 71 is automatically pressed out of the insertion hole 811.

[0053] See Figure 6 , further, the pulling part 8 further includes: a hook rod 83. The hook rod 83 is fixed to one end of the pull rod 81 located in the pulling hole 41, and the hook rod 83 is perpendicular to the pull rod 81. The hook rod 83 is more convenient for the staff to pull down the pull rod 81.

[0054] The working principle of the third embodiment is specifically as follows: During installation, insert the connecting rod 61 into the connecting hole 31 until the magnet one 62 and the magnet two 63 are magnetically attracted to each other, thereby completing the preliminary connection of the connecting seat 4 and the fixed pipe 3.

[0055] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this.
