Description

Technical Field

[0001] The invention relates to a vehicle frame weld grinding device, belonging to the technical field of grinding equipment. Background Art

[0002] During the manufacturing process of electric tricycle frames, some welding points on the frames, especially those located in narrow spaces, are difficult to reach with traditional grinding tools, resulting in insufficient grinding. There may be defects such as bumps and burrs on the surface of the welding points, which not only affects the aesthetics of the frame, but may also cause safety hazards to riders during use. The traditional grinding method often requires a lot of manpower and time, and the grinding effect is low. In particular, for key welding points on the frame, such as parts that are subjected to greater stress, if the grinding is uneven or excessive, the overall strength and durability of the frame may be reduced. Therefore, in order to overcome the shortcomings of traditional grinding methods, a frame weld grinding device is proposed. Summary of the invention

[0003] The object of the present invention is to provide a frame weld grinding device to solve the problems raised in the above background technology.

[0004] In order to achieve the above object, the present invention adopts the following technical solution: a frame weld grinding device, comprising:

[0005] A housing, wherein the housing is C-shaped;

[0006] A swivel, which is also C-shaped and rotatably connected to the inside of the housing, and the inner ring of the swivel is evenly provided with mounting grooves;

[0007] A plurality of brush holders, the brush holders are rotatably connected to the inside of the mounting groove, the rotating shafts of the brush holders are tangent to the circle where the inner ring of the rotating ring is located, and each brush holder is provided with a brush wire, and the ends of the brush wires face the center of the rotating ring;

[0008] Among them, an adjustment ring is arranged on one side of the rotating ring, and a plurality of sliders are evenly distributed on the adjustment ring. The plurality of sliders are respectively slidably connected inside corresponding installation grooves, and a first driving groove for driving the brush holder to rotate is opened on the side wall of the slider.

[0009] Preferably, the cross section of the first groove is in the shape of a dovetail groove, and the first groove has a first inclined wall and a second inclined wall. When the sliding block is slid, the first inclined wall or the second inclined wall drives the brush holder to rotate in different directions.

[0010] Preferably, two brush seats are rotatably connected inside each mounting groove, and a second slot is opened on the side wall of each slider, one brush seat is located inside the first slot, and the other brush seat is located inside the second slot;

[0011] The cross-section of the second groove is a parallelogram shape, and the second groove has a third inclined wall and a fourth inclined wall. The third inclined wall and the fourth inclined wall are inclined in the same direction as the first inclined wall. When the slider is slid, the third inclined wall or the fourth inclined wall drives the brush holder to rotate in the same direction.

[0012] Preferably, the inclination of the first inclined wall is greater than the inclination of the third inclined wall.

[0013] Preferably, the adjusting ring is provided with a plurality of adjusting bolts, the threaded ends of the plurality of adjusting bolts are meshingly connected to the rotating ring, and the adjusting bolts are provided with a spring for pressing the adjusting ring.

[0019] In the grinding process of the present invention, the rotation of the rotating ring drives the rotation of the brush holder, and then the brush wire moves in a circle around the welding point of the frame, thereby achieving comprehensive grinding of the welding point. At the same time, by adjusting the sliding block on the ring to slide in the corresponding installation groove, the angle of the brush holder can be adjusted, thereby changing the contact mode and strength between the brush wire and the welding point, and improving the flexibility and accuracy of grinding.

[0020] When the slider is slid, the first inclined wall moves close to the brush seat, and the lower end of the first inclined wall first contacts the side wall of the brush seat, so that the first inclined wall moves against the brush seat.

[0043] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0044] Embodiment 1

[0045] like Figure 1-Figure 11 As shown, in this embodiment, a frame weld grinding device is provided, including a shell 1, and the shell 1 is C-shaped, such as Figure 5 As shown, the shell 1 is formed by splicing two splicing shells 101; the shell 1 is rotatably connected to a swivel 2, which is also C-shaped, and the inner ring of the swivel 2 is evenly provided with a plurality of mounting grooves 201; each mounting groove 201 is rotatably connected to a brush holder 3, and the rotating shaft of the brush holder 3 is tangent to the circle where the inner ring of the swivel 2 is located, and each brush holder 3 is provided with a brush wire, and the end of the brush wire faces the center of the swivel 2; wherein, an adjusting ring 4 is provided on one side of the swivel 2, and a plurality of sliders 5 are evenly distributed on the adjusting ring 4, and the plurality of sliders 5 are respectively slidably connected to the inside of the corresponding mounting grooves 201, and the plurality of sliders 5 correspond to the plurality of brush holders 3 one by one, and the sliding direction of the slider 5 is parallel to the axis of the swivel 2, and the side wall of the slider 5 is provided with a first driving groove 501 for driving the brush holder 3 to rotate.

[0046] Grinding process: rotate the swivel 2 until it overlaps with the shell 1. At this time, place the workpiece to be grinded in the shell 1, start the swivel 2, and the swivel 2 rotates with the brush holder 3, causing the brush holder 3 to rotate with the brush wires, that is, the brush wires can rotate around the workpiece, move the shell 1 relative to the workpiece, and make the end of the brush wire contact the welding point of the workpiece. The end of the brush wire can grind the welding point of the workpiece. When the grinding is completed, the swivel 2 is rotated again to overlap with the shell 1. At this time, the workpiece can be removed from the shell 1 and the grinding is completed.

[0047] like Figure 5 As shown, in order to ensure the rotation of the rotating ring 2 in the housing 1, a plurality of supporting rollers 8 are evenly distributed inside the housing 1, and the plurality of supporting rollers 8 are rollingly connected to the outer ring of the rotating ring 2.

[0048] like Figure 4-Figure 5 As shown, in order to drive the swivel 2 to rotate in the housing 1, a power box 9 is fixed to one side of the housing 1, and a power shaft 10 is rotatably connected inside the power box 9. The power shaft 10 is transmission-connected to at least two support rollers 8 through a belt, and the axis of the power shaft 10 is arranged parallel to the rotating axis of the swivel 2, as shown in FIG. Figure 5As shown, the power shaft 10 is connected to the two support rollers 8 through two belts. The two support rollers 8 are driven rollers and rotate synchronously, and the other support rollers 8 are driven rollers. When the power shaft 10 rotates, the power shaft 10 rotates with the support rollers 8. A motor that drives the power shaft 10 to rotate can be installed in the power box 9. The power shaft 10 can be regarded as the rotating shaft of the motor. Since the motor is a prior art structure, it will not be described in detail and is not shown in the figure.

[0049] Among them, teeth are arranged on the side walls of the support roller 8 and the side walls of the rotating ring 2 , and each support roller 8 is meshedly connected with the teeth of the rotating ring 2 .

[0050] In addition, a connecting flange is provided on the side wall of the power box 9 , and the power box 9 can be connected to an external mechanical arm through the connecting flange, and the external mechanical arm can realize the movement and angle adjustment of the shell 1 .

[0051] like Figure 1-Figure 2 As shown, in order to enable the swivel 2 to stop at a position overlapping with the housing 1 so as to facilitate the placement of the workpiece into the housing 1, a position sensor 11 is fixed to the side wall of the power box 9 through a bracket, and a metal sheet 12 is fixed to the side wall of the swivel 2. When the metal sheet 12 rotates with the swivel 2 to the sensing area of ​​the position sensor 11, the swivel 2 stops at a position overlapping with the housing 1, that is, the swivel 2 and the housing 1 are in the position shown in FIG. Figure 1 In the state shown, the workpiece is placed in the housing 1.

[0052] Embodiment 2

[0053] like Figure 3 , Figure 9-11 As shown, based on the first embodiment, in order to be able to grind the welding point in a narrow space, the cross section of the first groove 501 is in the shape of a dovetail groove, such as Figure 9-11 As shown, the first pull groove 501 has a first inclined wall 5011 and a second inclined wall 5012, and the brush holder 3 is located between the first inclined wall 5011 and the second inclined wall 5012. The side walls of the brush holder 3 relative to the first inclined wall 5011 and the second inclined wall 5012 are flat, and the brush holder 3 extends from the close ends of the first inclined wall 5011 and the second inclined wall 5012. When the slider 5 is slid, the first inclined wall 5011 or the second inclined wall 5012 drives the brush holder 3 to rotate in different directions;

[0054] like Fig. 9 and Fig.10 As shown in FIG. 1 , when the slider 5 is slid to the right, the first inclined wall 5011 moves close to the brush holder 3, and the lower end of the first inclined wall 5011 first contacts the side wall of the brush holder 3, so that the first inclined wall 5011 moves against the brush holder 3. At this time, the brush holder 3 rotates to the right with the brush filaments. When the side wall of the brush holder 3 is attached to the first inclined wall 5011, the rotation of the brush holder 3 stops. At this time, the brush filaments form an angle with the end face of the rotating ring 2, as shown in FIG. Figure 3 As shown, the housing 1 is moved, and the workpiece to be polished is placed inside the housing 1 and the rotating ring 2. The rotating ring 2 is rotated, and the end of the brush wire rotates outside the rotating ring 2. The housing 1 is moved so that the end of the brush wire on one side is close to the welding point to be polished, thereby realizing the polishing of the welding point, especially the polishing of the welding point in a narrow space, for example: Figure 3 The welding point of two workpieces shown is ground in a Y-shape.

[0055] Similarly, if Fig. 9 and Fig.11 As shown, when the slider 5 is slid to the left, the second inclined wall 5012 drives the brush holder 3 to rotate in the opposite direction, which is beneficial for grinding the welding points of the workpiece from different directions. The process is the same as that of the first inclined wall 5011, so it is not repeated.

[0056] like Figure 6-Figure 8 As shown, the adjusting ring 4 is provided with a plurality of adjusting bolts 6, the threaded ends of the plurality of adjusting bolts 6 are meshedly connected to the rotating ring 2, and the adjusting bolts 6 are provided with a spring 7 for pressing the adjusting ring 4, as shown in FIG. Figure 8 As shown, the spring 7 is located between the swivel 2 and the adjusting ring 4. The spring 7 has a spring-pressing effect on the adjusting ring 4. When the adjusting bolt 6 is rotated to drive the adjusting ring 4 to move toward the swivel 2, the spring 7 is compressed. When the adjusting bolt 6 stops rotating, the spring 7 can ensure the relative position of the adjusting ring 4 and the swivel 2.

[0057] Embodiment 3

[0058] like Figure 3 , Figure 9-11 As shown, on the basis of the second embodiment, in order to further improve the grinding efficiency of the welding point in the narrow space, the interior of each mounting groove 201 is rotatably connected to two brush holders 3, and the side wall of each slider 5 is provided with a second shifting groove 502, one brush holder 3 is located inside the first shifting groove 501, and the other brush holder 3 is located inside the second shifting groove 502;

[0059] The cross section of the second groove 502 is in the shape of a parallelogram. Figure 9-11 As shown, the second slot 502 has a third inclined wall 5021 and a fourth inclined wall 5022, the brush holder 3 located in the second slot 502 is located between the third inclined wall 5021 and the fourth inclined wall 5022, the third inclined wall 5021 and the fourth inclined wall 5022 are arranged in parallel, the third inclined wall 5021 and the fourth inclined wall 5022 are both inclined in the same direction as the first inclined wall 5011, when the slider 5 is slid, the third inclined wall 5021 or the fourth inclined wall 5022 drives the brush holder 3 to rotate in the same direction;

[0060] like Fig. 9 and Fig.10 As shown, when the slider 5 is slid to the right, the first inclined wall 5011 moves close to the brush holder 3 in the first slot 501 and drives the brush holder 3 to swing to the right, while the third inclined wall 5021 moves close to the brush holder 3 in the second slot 502 and drives the brush holder 3 to swing to the right. In this state, the rotating ring 2 is driven to rotate, and the two layers of brush wires can improve the grinding efficiency.

[0061] And, if Fig. 9 and Fig.10 As shown, when the slider 5 is slid to the left, the second inclined wall 5012 moves close to the brush holder 3 in the first slot 501 and drives the brush holder 3 to swing to the left, while the fourth inclined wall 5022 moves close to the brush holder 3 in the second slot 502 and keeps the brush holder 3 in a state of swinging to the right. In this state, the brush wires on the two brush holders 3 in the same mounting groove 201 are separated, so that impurities accumulated in the brush wires can be cleaned up. By increasing the interval between the brush wires, the shedding of impurities is effectively promoted, and the cleaning ability of the brush wires is improved.

[0062] like Fig.11 The status shown is the status of regular cleaning of the brush wire. When the cleaning is completed, the brush wire is adjusted to Fig.10 The polishing status shown;

[0063] in addition, Figure 9-11 As shown, the brush holder 3 located in the second groove 502 has a plane extending upward on one side close to the fourth inclined wall 5022. When the slider 5 slides and drives the fourth inclined wall 5022 to move toward the brush holder 3, the brush holder 3 has enough plane to cooperate with the fourth inclined wall 5022, so that the fourth inclined wall 5022 can be used to stably maintain the brush holder 3 in a state of swinging to the right.

[0064] The inclination of the first inclined wall 5011 is greater than the inclination of the third inclined wall 5021 .

[0065] like Fig.10 As shown, when the two brush holders 3 in the same mounting groove 201 swing to the right at the same time, since the inclination of the first inclined wall 5011 is large, the swing amplitude of the brush holder 3 in the first groove 501 is large, and the inclination of the third inclined wall 5021 is small, so the swing amplitude of the brush holder 3 in the second groove 502 is small, so that the ends of the two brush wires will be relatively tight, which can increase the grinding force and improve the grinding efficiency.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
