[0042] like Figure 1 、 Figure 2 and Figure 8 As shown, a deburring and cleaning auxiliary device for the head of a heat-insulating profile comprises a main shaft 1, an end grinding mechanism 2 and a hole edge grinding mechanism 3. The end grinding mechanism 2 can be horizontally adjusted and installed on the outer ring of the main shaft 1 to wrap or expose the hole edge grinding mechanism 3. The hole edge grinding mechanism 3 is fixedly installed on one end of the main shaft 1, and the other end of the main shaft 1 is connected to the external rotating mechanism. The external rotating mechanism is mainly used to drive the main shaft 1 to rotate, so that the end grinding mechanism 2 can grind the end face of the circular hole, or drive the hole edge grinding mechanism 3 to grind the inner edge of the circular hole. The end grinding mechanism 2 comprises a sliding sleeve 5, a clamping mechanism 7, an angle adjustment mechanism 6, multiple rows of fixed grinding columns 2a from the outside to the inside, multiple rows of movable grinding columns 2b from the outside to the inside and multiple rows of movable blocks 2c from the outside to the inside. The sliding sleeve 5 can be horizontally slidably mounted on the main shaft 1, and the clamping mechanism is fixed It is installed in the sliding sleeve 5, and the clamping mechanism 7 is used to lock the adjusted sliding sleeve 5. After the worker pushes the sliding sleeve 5 to adjust the horizontal position, the position of the sliding sleeve 5 can be fixed by the clamping mechanism, so that the sliding sleeve 5 wraps or exposes the hole edge grinding mechanism 3. Multiple rows of fixed shafts are fixedly installed on the end of the sliding sleeve 5. Multiple rows of fixed shafts are evenly distributed along the circumferential direction along the end of the sliding sleeve 5. Multiple rows of fixed grinding columns 2a and multiple rows of movable grinding columns 2b are staggered, so that the contact surface is uniform during grinding. Multiple rows of movable grinding columns 2b are respectively fixedly connected to multiple rows of movable blocks 2c, and each movable grinding column 2b is installed on the corresponding movable block 2c. The movable block 2c is rotatably connected to the end of the sliding sleeve 5. The angle adjustment mechanism 6 is fixedly installed on the sliding sleeve 5. The angle adjustment mechanism 6 is used to simultaneously adjust the multiple rows of movable grinding columns 2b to rotate inward or outward.

[0043] When the end face of a circular hole is being polished, the sleeve 5 wraps around the outer ring of the end polishing mechanism 2, and the multiple rows of movable polishing columns 2b rotate inward. The worker slides the sleeve 5 outward and pushes it out, which is locked by the clamping mechanism 7. At this point, the sleeve 5 wraps around the hole edge polishing mechanism 3, meaning that the movable polishing column 2b and the fixed polishing column 2a are now at the very front of the device. The external rotating mechanism drives the fixed polishing column 2a and the movable polishing column 2b to rotate simultaneously, allowing the end of the circular hole to be polished. Before polishing, the worker adjusts the angle adjustment mechanism 6, causing the multiple rows of movable polishing columns 2b to rotate and tilt inward to increase the polishing area.

[0044] When grinding the inner wall diameter of the circular hole, the sliding sleeve 5 wraps the outer ring of the end grinding mechanism 2, and multiple rows of movable grinding columns 2b rotate outward; different from the above working method is that although the sliding sleeve 5 wraps the end grinding mechanism 2, the movable grinding columns 2b at this time are tilted and rotated outward. At this time, the device can be extended into the circular hole so that the outermost circle of movable grinding columns 2b can grind the inside of the circular hole.

[0045] When the inner end of the circular hole is polished, the sleeve 5 exposes the hole edge polishing mechanism 3, and the worker pushes the sleeve 5 inward to expose the hole edge polishing mechanism 3. At this time, the hole edge polishing mechanism 3 is located at the front end of the device. At this time, the device is driven to rotate by an external rotating mechanism, and then the worker operates the device to approach the circular hole to be polished, so that the inner hole edge of the circular hole can be polished.

[0046] The above three switching methods have the following effects: when workers deburr the head of the thermal insulation profile, there is no need to frequently replace the auxiliary device connected to the external rotating mechanism, making the operation more convenient for the workers.

[0047] like Figure 3 and Figure 4As shown, the spindle 1 includes a shaft body 1a and an external chuck 1b, wherein the shaft body 1a is fixedly connected to the external chuck 1b, and a circular groove A is provided at the connection between the shaft body 1a and the external chuck 1b for installing an adjustment ring 4c and a second bevel gear 4b. The hole edge grinding mechanism 3 is installed in the shaft body 1a, and the hole edge grinding mechanism 3 includes a grinding head 3a and a rotating assembly 4. The grinding head 3a is located at the end of the shaft body 1a, and the grinding head 3a is rotatably connected to the spindle 1, so that the grinding head 3a can be used for different straight The circular hole of the diameter is ground, and the rotating assembly 4 includes a first bevel gear 4a, a second bevel gear 4b and an adjusting ring 4c. The first bevel gear 4a is fixedly connected to one side of the grinding head 3a, and the adjusting ring 4c is installed on the circular groove A. The adjusting ring 4c is rotatably connected to the shaft body 1a. The second bevel gear 4b runs through both ends of the shaft body 1a, and the two ends of the second bevel gear 4b are respectively meshed with the first bevel gear 4a and the adjusting ring 4c. The grinding head 3a is rotated by rotating the adjusting ring 4c.

[0048] Through the above, the following effects are achieved. First, when workers are deburring the head of the insulation profile, when the diameter of the circular hole is smaller than the grinding head 3a in the horizontal state, the outer edge of the circular hole can be directly ground. When the diameter of the circular hole is larger than the grinding head 3a in the horizontal state, the grinding head 3a is rotated to a vertical direction by the rotating component 4 to grind the outer edge of the circular hole. Second, when the diameter of the circular hole is larger than the grinding head 3a in the horizontal state, the grinding head 3a can be passed through the circular hole to grind the circular hole on the inner wall.

[0049] like Figure 5 As shown, the spindle 1 also includes a plurality of sliders 1c and baffles 1d, wherein the sliders 1c are evenly distributed along the arc surface of the shaft body 1a, and a plurality of slots 1f are provided on the top of each slider 1c. The baffles 1d are located at the end of the sliders 1c, and the baffles 1d are fixedly connected to the sliders 1c and the shaft body 1a, respectively, so that when the shaft body 1a rotates, the sleeve 5 can be driven to rotate. The addition of the baffles 1d can limit the moving distance of the sleeve 5 and prevent the sleeve 5 from slipping out.

[0050] The inner cavity of the sliding sleeve 5 is provided with multiple sliding grooves 5a, each of which corresponds to each slider 1c one by one. Each sliding groove 5a is provided with multiple grooves 5b, and each groove 5b corresponds to the position of the card slot 1f. The clamping mechanism 7 is installed in the sliding groove 5a, and the clamping mechanism 7 includes a compression spring 7a and a buckle 7b. The two ends of the compression spring 7a are respectively in contact with the bottom of the groove 5b and the buckle 7b, which can effectively fix the position of the sliding sleeve 5 on the main shaft 1 to prevent the sliding sleeve 5 from moving during grinding and deburring.

[0051] like Figure 6As shown, the end of the sliding sleeve 5 is provided with a fixing groove 5c for installing multiple rows of movable blocks 2c, and both sides of the fixing groove 5c are provided with circular grooves B for rotating the multiple rows of movable blocks 2c, so that the multiple rows of movable blocks 2c can rotate inward and outward.

[0052] The angle adjustment mechanism 6 includes several worm wheels 6a and several worms 6b. The ratio of the number of worm wheels 6a to the number of multiple rows of movable blocks 2c is 1:1, and the worm wheel 6a is fixedly connected to the movable block 2c. The worm wheel 6a is meshed with the worm 6b. When the worm 6b rotates, it can drive multiple worm wheels 6a to rotate, and a gear 6c is provided at the top of the worm 6b, and the gear 6c is fixedly connected to the worm 6b.

[0053] The angle adjustment mechanism 6 also includes a rotating sleeve 6d, which has a plurality of locking holes 6e in the arc direction. The rotating sleeve 6d is fixed to the sliding sleeve 5 by screws to prevent the movable grinding column 2b from rotating inward or outward during end grinding. One side of the rotating sleeve 6d is provided with teeth, and the rotating sleeve 6d is meshed and connected with the gear 6c. The rotating sleeve 6d is rotatably installed on the sliding sleeve 5, so that when the rotating sleeve 6d rotates, it can drive all the movable grinding columns 2b to rotate inward or outward.

[0054] The length of the multiple rows of movable grinding columns 2b is greater than that of the multiple rows of fixed grinding columns 2a, in order to increase the contact area between the movable grinding columns 2b and the object when grinding inward or outward.

[0055] How it works;

[0056] When it is necessary to deburr the end face of an object, the worker slides out the sleeve 5, which will be locked by the clamping mechanism 7. At this time, the sleeve 5 will wrap around the hole edge grinding mechanism 3, that is, the movable grinding column 2b and the fixed grinding column 2a are located at the front end of the device. The fixed grinding column 2a and the movable grinding column 2b are driven to rotate simultaneously by the external rotating mechanism, so that the end of the object can be polished. Among them, before polishing, the worker adjusts the angle adjustment mechanism 6 so that the multiple rows of movable polishing columns 2b rotate and tilt inward to increase the polishing area. When the inside of the object needs to be polished, the movable polishing columns 2b are tilted and rotated outward. At this time, the device can be extended into the circular hole so that the outermost circle of movable polishing columns 2b can polish the inside of the circular hole. When polishing the circular hole, the worker pushes the sliding sleeve 5 inward to expose the hole edge polishing mechanism 3. At this time, the hole edge polishing mechanism 3 is located at the front end of the device. At this time, the device is driven to rotate by the external rotating mechanism, and then the worker operates the device to approach the circular hole to be polished, so that the inner hole edge of the circular hole can be polished.

[0057] It should be noted that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that various modifications, equivalent substitutions, and variations may be made to the present invention. However, as long as these modifications do not depart from the spirit of the present invention, they are intended to be within the scope of protection of the present invention. Furthermore, certain terms used in the specification and claims of this application are not intended to be limiting and are provided solely for ease of description.
