Technical Field

[0001] The present application relates to the technical field of power tool accessory processing equipment, and in particular to a grinding device for power tool accessory processing. Background Art

[0002] The expansion head is a special power tool connection accessory. Figure 1 The expansion head 7 includes a tube end 71 and a joint end 72, wherein the joint end 72 is designed to be conical and the tube end 71 is straight. In order to achieve a close fit between the two, the tube end 71 needs to be specially processed, that is, it is expanded into a bell mouth using a special tool to ensure good sealing performance.

[0003] During the processing of the expansion head 7 , grinding equipment is required to grind the outer wall of the tube end 71 and the inner wall of the joint end 72 to remove burrs, rough edges and other debris, thereby improving the production quality of the expansion head 7 .

[0004] When the existing grinding equipment performs the grinding operation on the expansion head, two grinding processes are usually required. One grinding process is to clamp the joint end and then grind the outer wall of the tube end, and the other grinding process is to clamp the tube end and then grind the inner wall of the joint end. The grinding operation of the outer wall of the tube end and the grinding operation of the inner wall of the joint end are performed separately, which greatly reduces the processing efficiency of the expansion head. This problem needs to be solved urgently. Summary of the invention

[0005] In order to improve the grinding efficiency of the expansion head, thereby improving the processing efficiency of the expansion head, the present application provides a grinding device for processing power tool accessories.

[0008] By adopting the above technical scheme, the frame supports the support adjustment mechanism, the clamping mechanism, the first grinding mechanism and the second grinding mechanism. When the expanding head needs to be ground, the support adjustment mechanism supports the expanding head horizontally, with the tube end facing the first grinding mechanism and the joint end facing the second grinding mechanism. Then the support adjustment mechanism drives the expanding head to move in the direction close to the first grinding mechanism, so that the first grinding mechanism can grind the outer wall of the tube end, and the second grinding mechanism can grind the inner wall of the joint end at the same time, which is beneficial to improving the grinding efficiency of the expanding head, thereby improving the processing efficiency of the expanding head. In the process of the first grinding mechanism and the second grinding mechanism performing grinding operations at the same time, the clamping mechanism presses the expanding head in the first grinding mechanism, which is beneficial to improving the stability of the expanding head during the grinding operation, and no manual control is required.

[0009] Preferably, the support adjustment mechanism includes a support component and an adjustment component, the adjustment component is arranged on the frame to drive the support component to move toward or away from the first grinding mechanism, and the support component is connected to the adjustment component to horizontally support the expansion head.

[0012] By adopting the above technical solution, the connecting rod connects the adjustment block and the first fixing member to the frame. When the first fixing member releases the fixation between the adjustment block and the connecting rod, the staff can drive the support assembly to rotate around the connecting rod as the axis by rotating the adjustment block, thereby realizing the adjustment of the position of the support assembly. When the support assembly is rotated to a position away from the first grinding mechanism, it is convenient for the staff to perform material replacement operations on the expansion head on the support assembly. When the support assembly is rotated in a direction close to the first grinding mechanism and the expansion head enters the first grinding mechanism, the first fixing member fixes the adjustment block on the connecting rod to improve the stability of the pipe end during the grinding operation in the first grinding mechanism.

The wheel surfaces of the grinding wheels grind the outer wall of the pipe end, and the two grinding wheels rotate in the same direction, so that the friction between the grinding wheels and the pipe end can drive the pipe end to rotate slowly, thereby realizing the grinding operation on the pipe end.

[0020] By adopting the above technical solution, the support frame supports the clamping member and the clamping drive member. When the two grinding wheels perform a grinding operation on the pipe end, the clamping drive member drives the clamping member to move toward the support rod so that the clamping member presses against the pipe end, which is beneficial to improving the stability of the pipe end during the grinding operation. At the same time, due to the stability of the pipe end, the joint end fixedly connected to the pipe end is also stable, which is further beneficial to improving the stability of the joint end during the grinding operation.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 2-6 This application is described in further detail.

[0040] The present application embodiment discloses a grinding device for processing electric tool accessories, referring to Figure 2, including a frame 1, on which a support adjustment mechanism 2, a clamping mechanism 3, a first grinding mechanism 4 and a second grinding mechanism 5 are arranged, the first grinding mechanism 4 and the second grinding mechanism 5 are arranged opposite to each other, when the expanding head 7 needs to be ground, the expanding head 7 is in a horizontal state and is located between the first grinding mechanism 4 and the second grinding mechanism 5, the tube end 71 faces the first grinding mechanism 4, so that the first grinding mechanism 4 can grind the outer wall of the tube end 71, and the joint end 72 faces the second grinding mechanism 5, so that the second grinding mechanism 5 can grind the inner wall of the joint end 72. The support adjustment mechanism 2 is connected to the frame 1 and is located on the side of the first grinding mechanism 4 away from the second grinding mechanism 5, and is used to horizontally support the expanding head 7 and drive the expanding head 7 to move in a direction close to or away from the first grinding mechanism 4. The expanding head 7 moves in a direction away from the first grinding mechanism 4 so that the staff can change the material of the expanding head 7, and the expanding head 7 moves in a direction close to the first grinding mechanism 4 to grind the expanding head 7. During the grinding process of the expansion head 7, the pressing mechanism 3 is located above the expansion head 7 and is used to press the expansion head 7 into the first grinding mechanism 4 to improve the stability of the grinding operation of the expansion head 7. The first grinding mechanism 4 performs the grinding operation on the outer wall of the tube end 71 and the second grinding mechanism 5 performs the grinding operation on the inner wall of the joint end 72 at the same time, which is beneficial to improving the grinding efficiency of the expansion head 7, thereby improving the processing efficiency of the expansion head 7.

[0041] Reference Figure 3 and Figure 4 The support and adjustment mechanism 2 includes a support assembly 21 and an adjustment assembly 22. The adjustment assembly 22 is arranged on the frame 1 and is used to drive the support assembly 21 to move toward or away from the first grinding mechanism 4. The support assembly 21 is connected to the adjustment assembly 22 and is used to horizontally support the expansion head 7. When the expansion head 7 needs to be ground, the staff places the expansion head 7 in the support assembly 21, and the support assembly 21 horizontally supports the expansion head 7. Then the adjustment assembly 22 drives the support assembly 21 to move toward the first grinding mechanism 4 to drive the pipe end 71 into the first grinding mechanism 4 for grinding. When the grinding operation of the expansion head 7 is completed, the adjustment assembly 22 drives the support assembly 21 to move away from the first grinding mechanism 4 to change the material and perform the next expansion head 7 grinding operation.

[0042] Reference Figure 3 and Figure 4The adjustment assembly 22 includes an adjustment block 221, a connecting rod 222 and a first fixing member. The connecting rod 222 is horizontally fixedly connected to the frame 1. The adjustment block 221 is arranged in a long strip shape. One end of the adjustment block 221 is rotatably sleeved on the connecting rod 222. The support assembly 21 is connected to the other end of the adjustment block 221. The first fixing member is arranged on the adjustment block 221 to fix the adjustment block 221 to the connecting rod 222. In this embodiment, the first fixing member is arranged as a first bolt 223. The first bolt 223 is threaded into the adjustment block 221 and is pressed against the side wall of the connecting rod 222 to achieve the fixing of the adjustment block 221 on the connecting rod 222. When the first bolt 223 is loosened, the adjustment block 221 rotates with the connecting rod 222 as the axis, thereby adjusting the position of the support assembly 21. When the first bolt 223 is tightened, the adjustment block 221 is fixed on the connecting rod 222 to achieve the fixing of the position of the support assembly 21.

[0043] Reference Figure 3 and Figure 4 The support assembly 21 includes a support rod 211 and a second fixing member. The support rod 211 is movably arranged at one end of the adjustment block 221 away from the connecting rod 222, and the support rod 211 is parallel to the connecting rod 222. The second fixing member is arranged on the adjustment block 221 to fix the support rod 211 to the adjustment block 221. The pipe end 71 is sleeved at one end of the support rod 211, and the pipe end 71 and the grinding position of the first grinding mechanism 4 are located on the same vertical plane. In this embodiment, the second fixing member is set as a second bolt 212, and the second bolt 212 is threaded into the adjustment block 221 and pressed against the side wall of the support rod 211 to achieve the fixing of the support rod 211 on the adjustment block 221. When the second bolt 212 is loosened, the support rod 211 can be moved along its length direction to adjust the position of the expansion head 7 so that the pipe end 71 and the grinding position of the first grinding mechanism 4 are on the same vertical plane.

[0044] Reference Figure 3 and Figure 5 When the pipe end 71 moves to the grinding position of the first grinding mechanism 4, the first grinding mechanism 4 performs a grinding operation on the pipe end 71. Specifically, the first grinding mechanism 4 includes two grinding wheels 41 and a first driving assembly 42 for driving the two grinding wheels 41 to rotate in the same direction. The two grinding wheels 41 are both vertically arranged. In this embodiment, the grinding position of the first grinding mechanism 4 is above the gap between the two grinding wheels 41. When the pipe end 71 moves to the top of the gap between the two grinding wheels 41 and abuts against the wheel surface of the grinding wheel 41, the wheel surfaces of the two grinding wheels 41 are arranged opposite to each other and rotate in the same direction to grind the outer wall of the pipe end 71.

[0045] Reference Figure 3 and Figure 5The first driving assembly 42 includes a first driving motor 421, a driving gear 422, two driven gears 423 and two first rotating shafts 424. The two first rotating shafts 424 are arranged in parallel, the two first rotating shafts 424 are rotatably connected to the frame 1 and are respectively coaxially fixed and penetrated through the two grinding wheels 41. The first driving motor 421 is horizontally fixedly arranged on the frame 1, the driving gear 422 is fixedly sleeved on the output shaft of the first driving motor 421, and the two driven gears 423 are respectively fixedly sleeved on the two first rotating shafts 424. The driving gear 422 and the two driven gears 423 are meshed. When the first driving motor 421 is started, the output shaft of the first driving motor 421 rotates to drive the driving gear 422 to rotate, and the driving gear 422 rotates to drive the two driven gears 423 meshed therewith to rotate in the same direction. The two driven gears 423 rotating in the same direction drive the two grinding wheels 41 to rotate in the same direction through the two first rotating shafts 424. It should be noted that, when the two grinding wheels 41 rotate to grind the tube end 71 , since the two grinding wheels 41 rotate in the same direction, the friction between the grinding wheels 41 and the tube end 71 can drive the tube end 71 to rotate slowly, thereby achieving comprehensive grinding of the outer wall of the tube end 71 .

[0046] Reference Figure 3 The clamping mechanism 3 includes a support frame 31, a clamping member 32 and a clamping driving member. The support frame 31 is arranged in a gantry shape, and is fixedly connected to the frame 1. The support frame 31 is located above the first grinding mechanism 4. When the pipe end 71 is sleeved on the support rod 211, the clamping member 32 is located directly above the pipe end 71. The clamping driving member is arranged on the support frame 31 to drive the clamping member 32 to move toward or away from the support rod 211.

When the grinding wheel 41 is grinding the outer wall of the pipe end 71 , the piston rod of the driving cylinder 33 is stretched to drive the pressing member 32 to move vertically downward. The pressing member 32 presses the pipe end 71 to improve the stability of the grinding process of the pipe end 71 .

[0047] Reference Figure 3 In order to improve the stability of the grinding process of the pipe end 71 and improve the smoothness of the rotation of the expansion head 7 during the grinding process, the clamping member 32 includes a clamping plate 321 and a clamping wheel 322. The clamping plate 321 is horizontally fixedly connected to the lower end of the piston rod of the driving cylinder 33, and the clamping wheel 322 is vertically rotatably connected to the bottom of the clamping plate 321, and the clamping wheel 322 and the two grinding wheels 41 are located on the same vertical plane.

[0048] Reference Figure 3 and Figure 6The second grinding mechanism 5 includes a sanding rod 51, a second driving assembly 52 and a displacement assembly. The displacement assembly is arranged on the frame 1 to drive the second driving assembly 52 to move toward or away from the first grinding mechanism 4. The second driving assembly 52 is arranged on the displacement assembly to drive the sanding rod 51 to rotate. One end of the sanding rod 51 is connected to the second driving assembly 52, and the other end of the sanding rod 51 is opposite to the inner hole of the joint end 72 sleeved on the support rod 211. It should be noted that in order to make the sanding rod 51 face the inner hole of the joint end 72, a structure for adjusting the position of the second grinding mechanism 5 is also provided on the frame 1. This structure makes the sanding rod 51 face the inner hole of the joint end 72 through adjustment of the X, Y, and Z axes, which will not be repeated here.

The support seat 521 is connected to the displacement component to support the second driving motor 522, the driving wheel 523, the driven wheel 524, the belt 525, the second rotating shaft 526 and the chuck 527. The displacement component uses a motor, a screw rod and a guide rail structure to drive the support seat 521 to move toward or away from the first grinding mechanism 4, thereby realizing the movement of the sanding rod 51 toward or away from the first grinding mechanism 4, which will not be elaborated here. The second rotating shaft 526 is horizontally rotatably connected to the support seat 521, and the second rotating shaft 526 is parallel to the first rotating shaft 424. The chuck 527 is fixedly connected to the second rotating shaft 526 and clamps the grinding wheel 41 at one end facing the first grinding mechanism 4.

It should be noted that when the expansion head 7 performs the grinding operation, the second rotating shaft 526, the grinding wheel 41, the expansion head 7 and the support rod 211 are located on the same straight line.

[0050] Reference Figure 2 A dust suction pipe 6 for dust suction is also provided on the frame 1. The dust suction pipe 6 is located between the first grinding mechanism 4 and the second grinding mechanism 5, and the pipe mouth of the dust suction pipe 6 is directly facing the expanding head 7 during grinding to prevent the flying of debris generated by the grinding operation to protect the health of the staff.

[0051] The implementation principle of a grinding device for processing power tool accessories in the embodiment of the present application is as follows: when it is necessary to grind the expansion head 7, the staff inserts the pipe end 71 into the support rod 211, and rotates the adjustment block 221 to make the outer wall of the pipe end 71 abut against the wheel surface of the grinding wheel 41, and then drives the cylinder 33 to drive the clamping wheel 322 to move downward, so that the clamping wheel 322 abuts against the outer wall of the pipe end 71, and the grinding wheel 41 rotating in the same direction comprehensively grinds the outer wall of the pipe end 71. At the same time, the displacement component drives the grinding rod 51 to penetrate into the hole of the joint end 72, and the rotating grinding rod 51 grinds the inner wall of the joint end 72. The clamping wheel 322 presses the expansion head 7 to improve the stability of the grinding operation. The grinding operation of the outer wall of the pipe end 71 and the grinding operation of the inner wall of the joint end 72 are performed simultaneously, which is beneficial to improving the grinding efficiency of the expansion head 7, thereby improving the processing efficiency of the expansion head 7.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
