DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 3 As shown, a device for automatically replacing grinding tools with a robot provided by an embodiment of the utility model comprises a mounting seat 1, a rotating block 2 is arranged on the front side of the mounting seat 1, four groups of fixed boxes 3 are fixedly installed on the surface of the rotating block 2, a grinding head 4 is arranged on one side of the fixed box 3, a second bevel gear 5 is arranged inside the fixed box 3, a rotating rod 6 is fixedly installed on one end of the second bevel gear 5, a rotating sleeve 8 is fixedly installed on one side of the grinding head 4, the rotating rod 6 and the rotating sleeve 8 are detachably installed, a placement groove 7 is opened inside the mounting seat 1, a first motor 9 is slidably installed inside the placement groove 7, a first bevel gear 10 is fixedly installed on the output end of the first motor 9, the first motor 9 slides to allow the first bevel gear 10 to engage or separate with the second bevel gear 5, a second motor 11 is fixedly installed inside the mounting seat 1, and the output end of the second motor 11 is fixedly installed with the rotating block 2.

[0022] The mounting rod 19 and the robot are mounted by welding or bolts. When the grinding head 4 is required to work, the first bevel gear 10 and the second bevel gear 5 are meshed by starting the electric push rod 13. At this time, the first bevel gear 10, the second bevel gear 5, the rotating rod 6 and the grinding head 4 are rotated in sequence by starting the first motor 9, so that the grinding disc can perform grinding work;

[0023] When a conical workpiece is encountered, the original circular grinding head 4 needs to be replaced. First, the electric push rod 13 can be started to pull the first motor 9 and the first bevel gear 10 back to the rear side, and then the second motor 11 can be started to drive the rotating block 2 to rotate. At this time, the rotating block 2 rotates 90 degrees to adjust the position of the conical grinding head 4, and then the conical grinding head 4 can be put into operation through the above steps;

[0024] If you encounter a workpiece grinding shape that is not commonly seen at this time, you need to manually disassemble the rotating rod 6 and the rotating sleeve 8, and then replace the grinding head 4 required at that time, while the commonly used grinding head 4 does not need to be disassembled, so that it is convenient to use later;

[0025] The grinding head 4 can be installed with a commonly used shape according to the actual use situation. When the rare grinding head 4 is used up, the original replaced grinding head 4 can be reinstalled for the next processing use.

[0026] Specifically, Figures 1 to 3 As shown, an electric push rod 13 is fixedly installed at the bottom of the inner wall of the placement groove 7, and the telescopic end of the electric push rod 13 is fixedly installed on the left side of the first motor 9. The electric push rod 13 is used to drive the first motor 9 to move, so that the first bevel gear 10 and the second bevel gear 5 are engaged.

[0027] Furthermore, when it is necessary to start the grinding head 4 to work, first start the electric push rod 13 to drive the first motor 9 and the first bevel gear 10 to move to the right, and the first bevel gear 10 moves to the right to engage with the second bevel gear 5. At this time, the grinding head 4 can be rotated to work by starting the first motor 9. When replacing the grinding head 4, the first motor 9 and the first bevel gear 10 need to be reset.

[0028] Specifically, Figures 1 to 3 As shown, the front side and the rear side of the inner wall of the placement groove 7 are fixedly installed with slide rails 14, and the front side and the rear side of the first motor 9 are fixedly installed inside the slide rails 14.

[0029] Furthermore, the arrangement of the slide rail 14 can reduce the friction between the first motor 9 and the placement slot 7 when the first motor 9 moves, thereby preventing the first motor 9 from being damaged due to long-term wear.

[0030] Specifically, Figures 1 to 3 As shown, a bearing seat 15 is fixedly installed on the top of the surface of the rotating rod 6, and one side of the bearing seat 15 is fixedly installed on one side of the fixed box 3.

[0031] Furthermore, the bearing seat 15 can reduce the friction between the rotating rod 6 and the fixed box 3, and can also improve the stability of the second bevel gear 5 and the rotating rod 6 during rotation, thereby preventing the second bevel gear 5 and the first bevel gear 10 from disengaging during operation.

[0032] Specifically, Figures 1 to 3 As shown, a bidirectional screw 16 is provided on the right side of each group of rotating sleeves 8, the bidirectional screw 16 is in contact with the surface of the rotating sleeve 8, the left end of the bidirectional screw 16 passes through the left side of the rotating sleeve 8, and an arc-shaped screw block 17 is threadedly installed on the surface of the bidirectional screw 16, and the right side of the arc-shaped screw block 17 is in contact with the left side of the rotating sleeve 8.

[0033] Furthermore, when the grinding head 4 needs to be replaced, the arc-shaped screw block 17 can be rotated toward the back first, and the arc-shaped screw block 17 will gradually disengage from the bidirectional screw 16. When the arc-shaped screw block 17 is completely disengaged from the bidirectional screw 16, the bidirectional screw 16 can be pulled toward the front side. When the bidirectional screw 16 is disengaged from the rotating rod 6 and the rotating sleeve 8 in turn, the existing grinding head 4 can be disassembled toward the bottom.

[0034] When installing the replaced grinding head 4, first let the rotating rod 6 completely enter the rotating sleeve 8, and then pass the two-way screw 16 to the left side of the rotating sleeve 8 in turn. At this time, the arc surface of the two-way screw 16 must be in contact with the surface of the rotating sleeve 8, and then twist the arc screw block 17 along the pointer to make its arc surface contact with the surface of the rotating sleeve 8, thereby improving the stability when installing the grinding head 4.

[0035] Specifically, Figures 1 to 3 As shown, a limiting screw block 18 is installed on the left thread of the surface of the bidirectional screw 16 , and the right side of the limiting screw block 18 is in contact with the left side of the arc-shaped screw block 17 .

[0036] Furthermore, to prevent the arc-shaped screw block 17 from rotating when the grinding head 4 is working, the limiting screw block 18 can be rotated counterclockwise at this time, and the limiting screw block 18 will contact the plane of the arc-shaped screw block 17 when it rotates. Since the arc-shaped screw block 17 is installed clockwise and the limiting screw block 18 is installed counterclockwise, the limiting screw block 18 will tightly limit the arc-shaped screw block 17.

[0037] Specifically, Figures 1 to 3 As shown, a mounting rod 19 is fixedly mounted on the left side of the mounting seat 1, and the left side of the mounting rod 19 is used for mounting with the robot.

[0038] Furthermore, the mounting rod 19 and the robot may be mounted by welding or bolts, and then the first motor 9, the second motor 11 and the electric push rod 13 may be controlled by the robot.

[0039] The above embodiments are only used to help understand the method and core idea of ​​the utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
