It should be noted that the clamping jaw 31 may also be a pneumatic clamping jaw or an electric clamping jaw in the prior art, and the structure and principle thereof are not detailed here.

The working process of the deburring device is as follows:

when the clamping grooves on the two vertical bars 12 are located on the inner side surfaces of the vertical bars 12, a worker firstly keeps the headrest rod 10 in the state shown in fig. 2, the cross bar 11 is in the vertical state at the moment, and the two vertical bars 12 are in the horizontal state and located on the unified vertical surface. Initially, the rotating arm 36 is in the vertical state shown in fig. 4, and the lower vertical rod 12 is transversely inserted into the groove 281 of the stopper 28, so that the clamping jaw 31 clamps the middle position of the cross rod 11, and the feeding operation of the headrest rod 10 is completed. Next, the belt wheel driving motor 23 is started to operate the endless abrasive belt 21, the lifting driving member 25 is started to move the endless abrasive belt 21 downward and press the lower vertical rod 12 (for example, the lower vertical rod is the first vertical rod, and the upper vertical rod is the second vertical rod), and at the same time, the friction driving mechanism 33 is started to make the rotating arm 36 swing back and forth around the swing center O (i.e., the center where the axis of the output shaft of the friction driving mechanism 33 is collinear with the groove 281), the rotating arm 36 swings back and forth to make the clamping jaw 31 drive the headrest rod 10 to rotate around the limiting block 28, and the first vertical rod rotates back and forth in the groove 281 and generates friction with the endless abrasive belt 21, so as to remove burrs on the inner side surface of the first vertical rod.

After the first vertical rod is deburred, the friction driving mechanism 33 stops rotating, the rotating arm 36 is in an initial vertical state, the clamping jaw 31 is also in an initial position, and then the second vertical rod can be switched to perform deburring work. Specifically, the lifting driving member 25 moves the endless abrasive belt 21 upward and away from the stopper 28, and the feeding driving mechanism 32 moves the rotating arm 36 backward to separate the first vertical rod from the stopper 28, so as to ensure that the two vertical rods 12 have a switching space. Next, the rotary driving member 341 rotates the clamping jaw 31 by 180 °, and the headrest rod 10 rotates by 180 ° with the clamping jaw 31, so that the second vertical rod without deburring is located below, and then the feed driving mechanism 32 is started to move the rotating arm 36 forward to insert the second vertical rod into the stopper 28, thereby completing the switching of the two vertical rods 12. The burrs on the inner surface of the second vertical bar can be removed in the same process as the removal of the burrs on the inner surface of the first vertical bar, which is not repeated herein. After the second vertical rod removes the burrs, the annular abrasive belt 21 moves upwards to be away from the limiting block 28, the clamping and operating device 30 returns to the initial state, and the worker takes off the headrest rod 10, so that the next headrest rod 10 can be deburred.

When the engaging groove of one of the vertical bars 12 is located on the inner side surface thereof and the engaging groove of the other vertical bar 12 is located on the outer side surface thereof, for example, the engaging groove of the first vertical bar is located on the inner side surface thereof and the engaging groove of the second vertical bar is located on the outer side surface thereof. After the deburring work of the inner side surface of the first vertical rod is completed, the process of switching the second vertical rod to remove burrs is specifically as follows: referring to fig. 6, the lifting driving member 25 first moves the endless belt 21 upward and away from the stopper 28, and the feeding driving mechanism 32 moves the rotating arm 36 backward to separate the first vertical rod 12 from the stopper 28, so as to ensure that two vertical rods 12 have a switching space. Next, the vertical driving member 342 drives the first mounting block 343 to move downward, the clamping jaw 31 and the headrest rod 10 move downward until the second vertical rod 12 is aligned with the recess 281 of the stopper 28, and then the feed driving mechanism 32 is started to move the rotating arm 36 forward to insert the second vertical rod into the stopper 28, so as to complete the switching of the two vertical rods 12. The burrs on the outer surface of the second vertical bar 12 can be removed, which is the same as the above-mentioned removal of the burrs on the inner surface of the first vertical bar, and will not be described again.

When the clamping grooves on the two vertical rods 12 are located on the outer side surfaces of the vertical rods 12, a worker firstly keeps the headrest rod 10 in the state shown in fig. 6, then transversely inserts the upper vertical rod 12 (which is the first vertical rod 12) into the groove 281 of the limiting block 28, so that the clamping jaw 31 clamps the middle position of the cross rod 11, the material loading work of the headrest rod 10 is completed, and then the process of removing burrs on the outer side surfaces of the first vertical rod 12 is the same as the process described above, and is not described again. After the deburring work of the first vertical rod is completed, the process of switching the second vertical rod 12 to remove burrs is as follows: the lifting driving part 25 moves the endless abrasive belt 21 upwards and away from the stopper 28, and the feeding driving mechanism 32 moves the rotating arm 36 backwards to separate the first vertical rod 12 from the stopper 28, so as to ensure that two vertical rods 12 have a switching space. Next, the rotary driving member 341 rotates the clamping jaw 31 by 180 °, the headrest rod 10 rotates by 180 ° with the clamping jaw 31, the second vertical rod without deburring is located above, and then the feed driving mechanism 32 is started to move the rotating arm 36 forward to insert the second vertical rod 12 into the stopper 28, so that switching between the two vertical rods 12 is completed. The burrs on the outer surface of the second vertical bar 12 can be removed, which is the same as the above-mentioned removal of the burrs on the outer surface of the first vertical bar 12, and will not be described again.

It should be noted that when deburring is performed on the headrest rods 10 of the same model in batches, only the initial positions of the rotating arm 36 and the clamping jaw 31 need to be adjusted for the first time, and then, the adjustment is not needed, so that the clamping jaw 31 can be clamped in the middle position of the cross rod 11, and therefore, after the headrest rods 10 rotate 180 degrees, the switched vertical rods 12 can still be inserted into the grooves 281 of the limiting blocks 28. For different types of headrest poles 10, the gripping jaws 31 can be moved up or down by the vertical drive 342 to adjust the initial position of the gripping jaws 31 when the distance between the two vertical bars 12 changes.

Example two

When the deburring device is used for removing the headrest rod 10 shown in fig. 1, the initial positions of the rotating arm 36 and the clamping jaw 31 are shown in fig. 9, the rotating arm 36 is vertically arranged, the clamping jaw 31 and the rotating arm 36 are in the same line, and the specific deburring process is the same as that of the first embodiment and is not repeated.

When the deburring device is used for deburring a headrest rod 10 shown in fig. 10, the initial positions of the rotating arm 36 and the clamping jaw 31 are as shown in fig. 11, the rotating arm 36 is vertically arranged, but the clamping jaw 31 is not in line with the rotating arm 36, for example, the clamping jaw 31 is positioned on the right side of the rotating arm 36, the second mounting block 345 can be driven to move rightwards by the transverse driving piece 344, so that the clamping jaw 31 is positioned on the right side of the rotating arm 36, the transverse distance between the clamping jaw 31 and the swinging center O is adjusted, and after the clamping jaw 31 clamps the middle position of the cross rod 11, one of the vertical rods 12 can be inserted into the groove 281 of the limiting block 28. The working process of removing the burr of the headrest rod 10 shown in fig. 10 using the deburring apparatus of the present embodiment is as follows:

when the locking grooves on the two vertical bars 12 are located on the inner side surfaces of the vertical bars 12, a worker firstly keeps the headrest rod 10 in the state shown in fig. 8 and 11, at this time, the cross bar 11 is in a vertical state and located on the right side of the rotating arm 36, and the two vertical bars 12 are in a horizontal state and located on the same vertical plane. Then, the lower vertical rod 12 (the first vertical rod) is transversely inserted into the groove 281 of the limiting block 28, so that the clamping jaw 31 on the right side clamps the middle position of the cross rod 11, and the headrest rod 10 is loaded. The process of removing the burrs on the inner side surface of the first vertical rod is the same as that of the first embodiment, and is not described again.

After the first vertical rod has been deburred, the friction drive 33 is stopped, the swivel arm 36 and the clamping jaw 31 are returned to the initial position of fig. 11, after which the second vertical rod 12 can be switched over for deburring. Specifically, as shown in fig. 8 and 12, the lifting driving element 25 moves the endless abrasive belt 21 upward and away from the stopper 28, and the feeding driving mechanism 32 moves the rotating arm 36 backward to separate the first vertical rod 12 from the stopper 28, so as to ensure that there is a switching space between the two vertical rods 12. Next, the rotary drive 341 drives the jaw 31 to rotate 180 °, the headrest rod 10 rotates 180 ° with the jaw 31, and the second vertical rod that is not deburred is located below, but now not aligned with the swing center O. Next, as shown in fig. 13, the lateral drive member 344 is actuated to move the jaw 31 to the left, and the headrest rod 10 moves with the jaw 31 to the left until the second vertical rod is aligned with the swing center O. The feed drive mechanism 32 is then actuated to move the rotatable arm 36 forward to insert the second vertical post into the stop 28, completing the switch between the two vertical posts 12. The burrs on the inner surface of the second stem 12 can be removed, which is the same as the first embodiment and will not be described again.

When the engaging groove on one of the vertical bars 12 is located on the inner side surface thereof and the engaging groove on the other vertical bar 12 is located on the outer side surface thereof, for example, the engaging groove on the first vertical bar is located on the inner side surface thereof and the engaging groove on the second vertical bar is located on the outer side surface thereof. After the deburring work of the inner side surface of the first vertical rod is completed, the process of switching the second vertical rod to remove burrs is as follows: referring to fig. 11 and 14, the lifting driving member 25 first moves the endless belt 21 upward and away from the stopper 28, and the feeding driving mechanism 32 moves the rotating arm 36 backward to separate the first vertical rod 12 from the stopper 28, so as to ensure that two vertical rods 12 have a switching space. Next, the vertical driving member 342 drives the first mounting block 343 to move downward, the clamping jaw 31 and the headrest rod 10 also move downward, the vertical distance between the clamping jaw 31 and the swing center O is changed until the second vertical rod above is aligned with the groove 281 of the stopper 28, and then the feed driving mechanism 32 is started to move the rotating arm 36 forward to insert the second vertical rod into the stopper 28, so that the switching of the two vertical rods 12 is completed. The burrs on the outer surface of the second vertical bar 12 can be removed, which is the same as the first embodiment and will not be described again.

When the clamping grooves on the two vertical rods 12 are located on the outer side surfaces of the vertical rods 12, a worker firstly enables the headrest rod 10 to keep the state shown in fig. 14, then transversely inserts the upper vertical rod 12 (which is a first vertical rod) into the groove 281 of the limiting block 28, so that the clamping jaw 31 clamps the middle position of the cross rod 11, the loading work of the headrest rod 10 is completed, and then the process of removing burrs on the outer side surfaces of the first vertical rods is the same as the process described above, and is not described again. After the deburring work of the first vertical rod is completed, when the second vertical rod is switched to remove burrs, as shown in fig. 14 and 15, the headrest rod 10 is driven to rotate 180 degrees by the rotating driving member 341, so that the second vertical rod which is not deburred is positioned above the first vertical rod, then as shown in fig. 16, the transverse driving member 344 is started to enable the headrest rod 10 to move leftwards until the second vertical rod 12 is aligned with the swing center O, and then the deburring work is performed.
