Part of the headrest rod is in a downwardly open 'U' shape structure, which comprises two vertical rods and a horizontal rod connecting the two vertical rods, and the two vertical rods are connected with the automobile seat.

[0003] In order to conveniently adjust the height of the headrest, a height-adjusting clamping groove is generally formed on the side wall of the two vertical rods by machining to remove material, and the clamping groove has burrs after machining and needs to be deburred.

[0004] In the prior art, the deburring work of the headrest rod is completed by manual assistance, specifically, a worker holds the headrest rod on a deburring machine. The deburring machine comprises a ring-shaped sand belt, a driving mechanism for driving the ring-shaped sand belt to run, and a limiting block for limiting the vertical rod of the headrest rod. During deburring, the ring-shaped sand belt runs, the worker holds the horizontal rod of the headrest rod, inserts one of the vertical rods into the limiting block of the deburring machine, and then rotates the vertical rod in the limiting block to remove the burrs on the surface of the vertical rod by friction between the vertical rod and the ring-shaped sand belt; then the vertical rod is taken out of the limiting block, the horizontal rod is held to move to switch the other vertical rod to the limiting block, and the other vertical rod is inserted into the limiting block to remove the burrs on the outer wall of the other vertical rod. Although the above-mentioned manual deburring method can well remove the burrs at the clamping groove of the vertical rod, the labor intensity of the worker is large. SUMMARY

[0005] The application aims to solve the technical problems in the prior art, and the purpose of the application is to provide a deburring equipment for a headrest rod of an automobile.

[0006] To achieve the above object, the present application adopts the following technical scheme: the deburring equipment for automobile headrest rod, the headrest rod comprises two vertical rods and a horizontal rod connecting the two vertical rods, the deburring equipment comprises a deburring machine and a clamping and rotating device, the clamping and rotating device can clamp the headrest rod and make it move and interact with the deburring machine to remove the burrs on the outer wall of the vertical rod; the deburring machine comprises a vertically arranged annular abrasive belt, an abrasive belt driving mechanism driving the annular abrasive belt to rotate, and a limiting block provided close to the annular abrasive belt and having a groove, the opening at the top of the groove is directly opposite to the surface of the annular abrasive belt, after the vertical rod is inserted into the groove, the surface of the vertical rod can abut against the annular abrasive belt and generate a force; the clamping and rotating device comprises a clamping jaw capable of clamping the horizontal rod and having an opening and closing state, a feed driving mechanism driving the clamping jaw to move forward and backward so that the vertical rod is inserted into or taken out of the limiting block, a friction driving mechanism driving the clamping jaw to rotate around the limiting block, and a switching driving mechanism driving the clamping jaw to move to switch the two vertical rods.

[0007] In the above technical scheme, the annular abrasive belt of the deburring equipment generates a friction force with the surface of the vertical rod to remove the burrs on the surface of the vertical rod; the clamping groove of the limiting block is used for limiting the vertical rod; the clamping jaw of the clamping and rotating device is used for clamping the headrest rod; the feed driving mechanism is used for inserting or taking out the vertical rod from the limiting block groove to realize the feed movement of the vertical rod; the friction driving mechanism drives the clamping jaw to move around the limiting block, so that the vertical rod rotates in the groove of the limiting block and generates a friction force with the annular abrasive belt to remove the burrs on the surface of the vertical rod; the switching driving mechanism is used for switching the two vertical rods, and the deburring work of the two vertical rods can be completed by clamping once.

[0008] The present application clamps the headrest rod and makes it move by setting the clamping and rotating device, so that the automatic deburring work of the two vertical rods of the headrest rod is realized, only manual feeding and discharging are needed, and the labor intensity of the person is greatly reduced.

[0009] In a preferred embodiment of the present application, the friction driving mechanism is installed on the transversely moving frame, the feed driving mechanism drives the transversely moving frame to move linearly forward and backward, the output shaft of the friction driving mechanism is fixedly connected with a rotating arm, the switching driving mechanism is installed on the rotating arm, and the axis of the output shaft of the friction driving mechanism is collinear with the groove of the limiting block.

[0010] In the above technical scheme, the axis of the output shaft of the friction driving mechanism is collinear with the groove of the limiting block, the friction driving mechanism drives the rotating arm to rotate, so that the clamping jaw rotates around the axis of the output shaft of the friction driving mechanism, and thus the vertical rod clamped by the clamping jaw rotates in the groove of the limiting rod to remove the burrs on the surface of the vertical rod. The structure for driving the vertical rod to rotate is simple and reliable in operation.

[0011] In a preferred embodiment of the present application, the switching driving mechanism has at least one of the following structures: structure one: the switching driving mechanism comprises a rotary driving member for driving the clamping jaw to rotate to switch the two vertical rods; structure two: the switching driving mechanism comprises a vertical driving member for driving the clamping jaw to move vertically to switch the two vertical rods; when structure one and structure two are provided at the same time, the rotary driving member is installed on a first mounting block which is vertically slidingly connected with the rotating arm, and the vertical driving member drives the first mounting block to move vertically on the rotating arm.

[0012] In the above technical solution, the rotary driving member is provided to rotate the headrest rod by 180° around the clamping jaw to switch the two vertical rods, which is suitable for the case that the clamping grooves on the two vertical rods are located on the inner side surface of the vertical rods or the case that the clamping grooves on the two vertical rods are located on the outer side surface of the vertical rods. The vertical driving member is provided to move the clamping jaw vertically on the rotating arm to switch the two vertical rods, which is suitable for the case that the clamping groove is provided on the outer side surface of one of the vertical rods and the clamping groove is provided on the inner side surface of the other vertical rod. Moreover, the vertical driving member is used to move the clamping jaw vertically on the rotating arm to adjust the vertical distance between the clamping jaw and the output shaft of the friction driving mechanism, so that the distance between the two vertical rods of different headrest rods can be adapted, and the deburring device can complete the deburring work of more types of headrest rods.

[0013] In a preferred embodiment of the present application, the switching driving mechanism further comprises a transverse driving member for driving the rotary driving member to move in the left-right direction perpendicular to the rotating arm.

[0014] In the above technical solution, the transverse driving member is additionally provided, so that the transverse distance between the clamping jaw and the output shaft of the friction driving mechanism can be adjusted. The deburring device can also be used for the deburring work of the headrest rod whose horizontal rod and vertical rod are not in the same plane and whose vertical rod is connected with the horizontal rod through a bending section, thereby further improving the versatility of the deburring device.

[0017] In the above technical solution, the headrest rod is clamped by the spring, and the spring does not need too much elastic force because the weight of the headrest rod is relatively light.

[0020] In another preferred embodiment of the present application, the opposite inner sides of the two clamping blocks are provided with arc-shaped grooves, and the cross bar can be clamped and fixed in the arc-shaped grooves of the two clamping blocks.

[0021] In the above technical solution, the arc-shaped grooves are provided to limit the transverse position of the cross bar, avoiding the back-and-forth movement of the vertical bar in the groove of the limiting block during the deburring process.

[0022] In another preferred embodiment of the present application, the abrasive belt driving mechanism comprises three belt pulleys arranged in a triangular shape, and a belt pulley driving motor connected with one of the belt pulleys to drive the rotation thereof, and the three belt pulleys are connected through the annular abrasive belt arranged around the outside thereof.

[0023] In the above technical solution, the three belt pulleys are connected with the annular abrasive belt, which makes the operation of the annular abrasive belt more stable and improves the reliability of the deburring machine.

[0024] In another preferred embodiment of the present application, the abrasive belt driving mechanism is installed on the vertical moving frame, and the vertical moving frame is connected with a lifting driving member driving the vertical movement thereof, and the lifting driving member drives the vertical movement of the vertical moving frame to make the annular abrasive belt approach or move away from the limiting block.

[0025] In the above technical solution, the lifting driving member is provided to move the annular abrasive belt to approach or move away from the limiting block. When the vertical bar is inserted, the annular abrasive belt moves away from the limiting block, so that the insertion of the vertical bar is more easy; when deburring, the annular abrasive belt approaches the limiting block, and the position in contact with the vertical bar protrudes upward, so as to increase the pressing force on the vertical bar and improve the friction force on the surface of the vertical bar, which is beneficial to quickly remove the burrs on the surface of the vertical bar.

[0048] Example 1

[0049] This embodiment provides a deburring device for automotive headrest rods, such as... Figure 1 As shown, in this embodiment, the headrest rod 10 includes two vertical rods 12 and a horizontal rod 11 connecting the two vertical rods 12. The two vertical rods 12 are arranged in parallel, and the two vertical rods 12 and the horizontal rod 11 are located in the same plane. Each of the two vertical rods 12 has a slot (not shown in the figure) on its outer wall for adjusting the headrest height. The slot is located on the inner surface of the vertical rod 12 (the inner surface is the side of the two vertical rods 12 that is close to each other) or on the outer surface of the vertical rod 12 (the outer surface is the side of the two vertical rods 12 that is far apart from each other).

[0050] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the deburring device includes a deburring machine 20 and a clamping and rotating device 30. The clamping and rotating device 30 can clamp the headrest rod 10 and make it move, and interact with the deburring machine 20 to remove burrs on the outer wall of the vertical rod 12. Figure 2 The deburring machine 20 is shown as being positioned at the front of the clamping and rotating device 30. Figure 2 The left and right directions in the middle refer to the front and back directions of the deburring equipment, which are perpendicular to the direction of the deburring equipment. Figure 2 The direction of the paper shown is the left-right direction of the deburring equipment.

[0051] In this invention, the deburring machine 20 can employ existing technology, and this invention does not modify it, for example... Figure 2 and Figure 3 As shown, the deburring machine 20 includes a vertically arranged annular sanding belt 21, a sanding belt drive mechanism for driving the annular sanding belt 21, and a limiting block 28 with a groove 281 disposed near the annular sanding belt 21. The sanding belt drive mechanism and the limiting block 28 are mounted on the frame 40. The sanding belt drive mechanism is located on the front side of the annular sanding belt 21, and the limiting block 28 is located directly below the annular sanding belt 21. The opening at the top of the groove 281 faces the lower surface of the annular sanding belt 21. After the vertical rod 12 is inserted laterally into the groove 281 from back to front, the top of the vertical rod 12 protrudes outside the groove 281, and the surface of the vertical rod 12 can press against the annular sanding belt 21 and generate force.

[0052] Specifically, such as Figure 3As shown, the sand belt driving mechanism comprises three belt pulleys 22 arranged in a triangle, and a belt pulley driving motor 23 connected with one of the belt pulleys 22 to drive the rotation of the belt pulley 22. The three belt pulleys 22 are connected by a ring-shaped sand belt 21 arranged around the three belt pulleys 22. For example, the three belt pulleys 22 are arranged in an upright isosceles triangle, the output shaft of the belt pulley driving motor 23 is coaxially fixed with the uppermost belt pulley 22, the belt pulley driving motor 23 is bolted on the top of a vertical moving frame 24, the lower end of the vertical moving frame 24 is connected with a lifting driving member 25 to drive the vertical movement of the vertical moving frame 24, the lifting driving member 25 can be a telescopic cylinder, a pneumatic cylinder or a hydraulic cylinder, the lifting driving member 25 is bolted on the rack 40, and the lifting driving member 25 drives the vertical moving frame 24 to move vertically to make the ring-shaped sand belt 21 close to or away from the limiting block 28. Preferably, a vertical guide rail 26 is fixed on the rack 40, and a sliding block 27 vertically slidingly connected with the guide rail 26 is fixed on the vertical moving frame 24.

[0053] As shown in Figure 2 and Figure 4 , the clamping and rotating device 30 comprises a clamping jaw 31 capable of clamping the cross rod 11 in an open and closed state, a feeding driving mechanism 32 driving the clamping jaw 31 to move forward and backward to insert or take out the vertical rod 12 into or out of the limiting block 28, a friction driving mechanism 33 driving the clamping jaw 31 to rotate around the limiting block 28, and a switching driving mechanism 34 driving the clamping jaw 31 to move to switch the two vertical rods 12. In this embodiment, the friction driving mechanism 33 is a reversible motor, the friction driving mechanism 33 is installed on a horizontal moving frame 35, and the horizontal moving frame 35 is slidingly connected to the rack 40. The feeding driving mechanism 32 is a telescopic cylinder, a pneumatic cylinder or a hydraulic cylinder installed on the rack 40, the front end of the feeding driving mechanism 32 is fixed with the horizontal moving frame 35, and the feeding driving mechanism 32 drives the horizontal moving frame 35 to move linearly forward and backward. The output shaft 331 of the friction driving mechanism is fixed with a rotating arm 36 located on the front side of the output shaft 331, and the rotating arm 36 is vertically arranged in a normal state. The switching driving mechanism 34 is installed on the rotating arm 36, and the axis of the output shaft 33 of the friction driving mechanism is collinear with the groove 281 of the limiting block 28 in the horizontal direction.

[0054] In this embodiment, the switching driving mechanism 34 has at least one of the following structures; structure one: the switching driving mechanism 34 comprises a rotating driving member 341 driving the clamping jaw 31 to rotate to switch the two vertical rods 12, and the rotating driving member 341 is a reversible motor; structure two: the switching driving mechanism 34 comprises a vertical driving member 342 driving the clamping jaw 31 to move vertically to switch the two vertical rods 12, and the vertical driving member 342 is a telescopic cylinder, a pneumatic cylinder or a hydraulic cylinder. Preferably, structure one and structure two are provided at the same time, and the rotating driving member 341 is installed on a first mounting block 343 slidingly connected with the rotating arm 36 in the vertical direction, and the vertical driving member 342 drives the first mounting block 343 to move vertically on the rotating arm 36.

[0055] like Figure 7 As shown, in this invention, the gripper 31 includes a base 311 fixedly connected to the rotary drive member 341 of the switching drive mechanism 34, and two opposing gripping blocks 312 mounted on the base 311. The base 311 has a U-shaped structure with an open front end. At least one of the gripping blocks 312 is elastically connected to the base 311 via a spring 313. Under the elastic force of the spring 313, the two gripping blocks 312 can clamp the crossbar 11. Preferably, both gripping blocks 312 are elastically connected to the base 311 via springs 313. By compressing the spring 313, the gripping blocks 312 can slide on the base 311 to open the gripper 31. The outer ends of the two gripping blocks 312 ( Figure 7 The front end shown is provided with a guide part 314 to facilitate the insertion of the crossbar 11. The inner sides of the two clamping blocks 312 are provided with arc-shaped grooves 315, and the crossbar 11 can be clamped and fixed in the arc-shaped grooves 315 of the two clamping blocks 312. The arc-shaped grooves 315 are provided with anti-slip pads (not shown in the figure).

[0056] Normally, the opening of the gripper 31 faces forward, and the two clamping blocks 312 are positioned opposite each other. When it is necessary to clamp the crossbar 11 of the headrest bar 10, the crossbar 11 is in a vertical position. The worker moves the crossbar 11 of the headrest bar 10 backward. Under the guidance of the guide part 314, the crossbar 11 can smoothly enter between the two clamping blocks 312. If the crossbar 11 continues to move backward, the crossbar 11 overcomes the elastic force of the spring 313 and causes the two clamping blocks 312 to move away from each other. The crossbar 11 is inserted into the arc-shaped groove 315. Under the action of the spring 313, the two clamping blocks 312 clamp the crossbar 11.

[0057] It should be noted that the gripper 31 can also be a pneumatic gripper or an electric gripper, which are existing technologies, and their structure and principle will not be described in detail here.

[0058] The working process of this deburring equipment is as follows:

[0059] When the slots on both vertical rods 12 are located on the inner surface of the vertical rods 12, the worker first keeps the headrest rod 10 in place. Figure 2 As shown, the horizontal bar 11 is vertical, and the two vertical bars 12 are horizontal and located in the same vertical plane. Initially, the rotating arm 36 is in... Figure 4The vertical state is shown, the lower vertical rod 12 is inserted into the groove 281 of the limiting block 28 transversely, the clamping jaw 31 clamps the middle position of the horizontal rod 11, and the feeding of the headrest rod 10 is completed. Next, the belt wheel driving motor 23 is started to drive the annular abrasive belt 21 to rotate, the lifting driving part 25 is started to drive the annular abrasive belt 21 to move downward and press the lower vertical rod 12 (for example, the lower one is the first vertical rod, and the upper one is the second vertical rod), and the friction driving mechanism 33 is started to drive the rotating arm 36 to swing left and right 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 left and right swinging of the rotating arm 36 drives the clamping jaw 31 to rotate the headrest rod 10 around the limiting block 28, and the first vertical rod rotates in the groove 281 and generates friction with the annular abrasive belt 21 to remove the burrs on the inner side surface of the first vertical rod.

[0060] After the first vertical rod is deburred, the friction driving mechanism 33 is stopped, the rotating arm 36 is in the initial vertical state, and the clamping jaw 31 is also in the initial position. Then, the second vertical rod can be switched for deburring. Specifically, the lifting driving part 25 drives the annular abrasive belt 21 to move upward and away from the limiting block 28, and the feeding driving mechanism 32 drives the rotating arm 36 to move backward to make the first vertical rod away from the limiting block 28, so that the two vertical rods 12 have switching space. Next, the rotating driving part 341 drives the clamping jaw 31 to rotate 180°, and the headrest rod 10 rotates 180° with the clamping jaw 31, so that the second vertical rod which has not been deburred is located below. Then, the feeding driving mechanism 32 is started to drive the rotating arm 36 to move forward to insert the second vertical rod into the limiting block 28, and the switching of the two vertical rods 12 is completed. Then, the burrs on the inner side surface of the second vertical rod can be removed, and the process is the same as that of removing the burrs on the inner side surface of the first vertical rod, which will not be repeated. After the second vertical rod is deburred, the annular abrasive belt 21 moves upward and away from the limiting block 28, and the clamping rotating device 30 returns to the initial state. The worker takes down the headrest rod 10, and the deburring work of the next headrest rod 10 can be carried out.

[0061] When the clamping groove on one of the vertical rods 12 is located on the inner side surface thereof, and the clamping groove on the other vertical rod 12 is located on the outer side surface thereof, for example, the clamping groove on the first vertical rod is located on the inner side surface thereof, and the clamping groove on the second vertical rod 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 for deburring is as follows: in combination with the above description of the deburring process of the first vertical rod, the rotating arm 36 is driven to move forward to insert the second vertical rod into the limiting block 28, and the rotating arm 36 is driven to move backward to make the second vertical rod away from the limiting block 28. Then, the rotating driving part 341 is driven to rotate 180°, and the headrest rod 10 rotates 180° with the clamping jaw 31, so that the second vertical rod which has not been deburred is located below. Then, the feeding driving mechanism 32 is started to drive the rotating arm 36 to move forward to insert the second vertical rod into the limiting block 28, and the switching of the two vertical rods 12 is completed. Then, the burrs on the inner side surface of the second vertical rod can be removed, and the process is the same as that of removing the burrs on the inner side surface of the first vertical rod, which will not be repeated. After the second vertical rod is deburred, the annular abrasive belt 21 moves upward and away from the limiting block 28, and the clamping rotating device 30 returns to the initial state. The worker takes down the headrest rod 10, and the deburring work of the next headrest rod 10 can be carried out. Figure 6As shown, the lifting drive 25 first moves the annular sanding belt 21 upward away from the limiting block 28. The feed drive mechanism 32 moves the rotating arm 36 backward so that the first vertical rod 12 disengages from the limiting block 28, ensuring that the two vertical rods 12 have space to switch. Next, the vertical drive 342 drives the first mounting block 343 downward, and the gripper 31 and headrest rod 10 also move downward until the second vertical rod 12 is aligned with the groove 281 of the limiting block 28. Then, the feed drive mechanism 32 is activated to move the rotating arm 36 forward to insert the second vertical rod into the limiting block 28, completing the switching of the two vertical rods 12. The burrs on the outer surface of the second vertical rod 12 can then be removed, the process of which is the same as that for removing the burrs on the inner surface of the first vertical rod, and will not be described again.

[0062] When the slots on both vertical rods 12 are located on the outer surface of the vertical rods 12, the worker first keeps the headrest rod 10 in place. Figure 6 In the indicated state, the upper vertical rod 12 (the first vertical rod 12) is then horizontally inserted into the groove 281 of the limiting block 28, so that the gripper 31 clamps the middle position of the horizontal rod 11, completing the loading of the headrest rod 10. The process of removing burrs from the outer surface of the first vertical rod 12 is the same as described above and will not be repeated. After completing the deburring of the first vertical rod, the process of switching to deburring the second vertical rod 12 is as follows: the lifting drive 25 moves the annular sanding belt 21 upward away from the limiting block 28, and the feed drive mechanism 32 moves the rotating arm 36 backward so that the first vertical rod 12 disengages from the limiting block 28, ensuring that the two vertical rods 12 have space to switch. Next, the rotary drive 341 drives the gripper 31 to rotate 180°, and the headrest rod 10 rotates 180° with the gripper 31. The second vertical rod that has not been deburred is positioned above. Then, the feed drive mechanism 32 is activated to move the rotating arm 36 forward to insert the second vertical rod 12 into the limiting block 28, completing the switching of the two vertical rods 12. The burrs on the outer surface of the second vertical rod 12 can then be removed, the process of which is the same as that described above for removing burrs from the outer surface of the first vertical rod 12, and will not be repeated here.

[0063] It should be noted that when deburring headrest rods 10 of the same model in batches, only the initial positions of the rotating arm 36 and the gripper 31 need to be adjusted initially. No further adjustments are required afterward to ensure that the gripper 31 can be held in the middle position of the horizontal bar 11. Therefore, after the headrest rod 10 rotates 180°, the switched vertical bar 12 can still be inserted into the groove 281 of the limiting block 28. For different models of headrest rods 10, when the distance between the two vertical bars 12 changes, the gripper 31 can be moved upward or downward by the vertical drive component 342 to adjust its initial position.

[0068] The burr removing device of the embodiment can remove the burrs on the two vertical rods 12 of the headrest rod 10 shown in the figure, and can also remove the burrs on the two vertical rods 12 of the headrest rod 10 shown in the figure. Figure 10 The burr removing device of the embodiment can remove the burrs on the two vertical rods 12 of the headrest rod 10 shown in the figure, and can also remove the burrs on the two vertical rods 12 of the headrest rod 10 shown in the figure. Figure 11 As shown in the embodiment, the switching driving mechanism 34 further comprises a transverse driving member 344 for driving the rotary driving member 341 to move in the left-right direction perpendicular to the rotary arm 36, and the transverse driving member 344 is a telescopic cylinder, a pneumatic cylinder or a hydraulic cylinder. The transverse driving member 344 is installed on a second mounting block 345 which is in transverse sliding connection with the first mounting block 343, and the rotary driving member 341 is bolted to the front side of the second mounting block 345, and the transverse driving member 344 drives the second mounting block 345 to move transversely on the first mounting block 343. Figure 10 The burr removing device of the embodiment can remove the burrs on the two vertical rods 12 of the headrest rod 10 shown in the figure, and can also remove the burrs on the two vertical rods 12 of the headrest rod 10 shown in the figure.

[0069] When the clamping grooves on the two vertical rods 12 are located on the inner side surface of the vertical rod 12, the worker first holds the headrest rod 10 as shown in the figure, and then drives the rotary arm 36 to rotate to the left, so that the clamping grooves on the two vertical rods 12 are located on the outer side surface of the vertical rod 12. Figure 8 Figure 11 ​In the state shown, the cross bar 11 is in vertical state and located at the right side of the rotating arm 36, and the two vertical bars 12 are in horizontal state and located in the same vertical plane. Then the lower vertical bar 12 (as the first vertical bar) is inserted into the groove 281 of the limiting block 28 transversely, the right clamping jaw 31 clamps the middle position of the cross bar 11, and the feeding of the headrest bar 10 is completed. The burrs on the inner side surface of the first vertical bar are removed, and the process is the same as that of the first embodiment, which will not be described here.

[0070] After the burrs on the first vertical bar are removed, the friction driving mechanism 33 stops rotating, the rotating arm 36 and the clamping jaw 31 return to the initial position Figure 11 , and then the second vertical bar 12 can be switched to remove the burrs. Specifically, as shown in Figure 8 and Figure 12 , the lifting driving member 25 moves the annular abrasive belt 21 upward away from the limiting block 28, and the feeding driving mechanism 32 moves the rotating arm 36 backward to make the first vertical bar 12 away from the limiting block 28, so that the two vertical bars 12 have switching space. Next, the rotating driving member 341 drives the clamping jaw 31 to rotate 180°, and the headrest bar 10 rotates 180° with the clamping jaw 31, and the second vertical bar without burrs is located at the lower side, but at this time the lower second vertical bar is not aligned with the swing center O. Next, as shown in Figure 13 , the transverse driving member 344 is started to move the clamping jaw 31 to the left, and the headrest bar 10 moves to the left with the clamping jaw 31 until the second vertical bar is aligned with the swing center O. Then the feeding driving mechanism 32 is started to move the rotating arm 36 forward to insert the second vertical bar into the limiting block 28, and the switching of the two vertical bars 12 is completed. Next, the burrs on the inner side surface of the second vertical bar 12 can be removed, and the process is the same as that of the first embodiment, which will not be described here.

[0071] When the clamping slot on one of the vertical bars 12 is located on the inner side surface thereof, and the clamping slot on the other vertical bar 12 is located on the outer side surface thereof, for example, the clamping slot on the first vertical bar is located on the inner side surface thereof, and the clamping slot on the second vertical bar is located on the outer side surface thereof. After the burrs on the inner side surface of the first vertical bar are removed as described above, the process of removing the burrs on the second vertical bar is as follows: in combination with Figure 11 and Figure 14As shown, the lifting drive 25 first moves the annular sanding belt 21 upward away from the limiting block 28. The feed drive mechanism 32 moves the rotating arm 36 backward so that the first vertical rod 12 disengages from the limiting block 28, ensuring that the two vertical rods 12 have space to switch. Next, the vertical drive 342 drives the first mounting block 343 downward, and the gripper 31 and headrest rod 10 also move downward, changing the vertical distance between the gripper 31 and the swing center O until the upper second vertical rod is aligned with the groove 281 of the limiting block 28. Then, the feed drive mechanism 32 is activated to move the rotating arm 36 forward to insert the second vertical rod into the limiting block 28, completing the switching of the two vertical rods 12. The burrs on the outer surface of the second vertical rod 12 can then be removed, the process of which is the same as in Embodiment 1 and will not be described again.

[0072] When the slots on both vertical rods 12 are located on the outer surface of the vertical rods 12, the worker first keeps the headrest rod 10 in place. Figure 14 In the state shown, the upper vertical rod 12 (the first vertical rod) is then horizontally inserted into the groove 281 of the limiting block 28, so that the gripper 31 clamps the middle position of the horizontal rod 11, completing the loading of the headrest rod 10. The process of removing burrs from the outer surface of the first vertical rod is the same as described above and will not be repeated. After completing the deburring of the first vertical rod, when switching to deburring the second vertical rod, as shown... Figure 14 and Figure 15 As shown, the headrest rod 10 needs to be rotated 180° by the rotary drive component 341 first, so that the second vertical rod without deburring is at the top, and then... Figure 16 As shown, the transverse drive 344 is then activated to move the headrest rod 10 to the left until the second vertical rod 12 is aligned with the swing center O. After that, the deburring work is carried out. The specific process is the same as described above and will not be repeated here.
