Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to an auxiliary positioning device for an angle grinder. Background Technology

[0002] In existing technologies, when using an angle grinder to grind the weld seams of a product, it is often necessary to clamp and position the angle grinder using a positioning fixture to prevent deviation during processing. However, existing positioning fixtures are not well-suited for products of different specifications and sizes. When dealing with products of different specifications and sizes, it is necessary to change to a matching positioning fixture, which increases production costs. Utility Model Content

[0007] The first pressing roller and the second pressing roller are rotatably connected to the first limiting member and the second limiting member, respectively. The first pressing roller and the second pressing roller are used to roll and abut against different surfaces of the product to be processed.

[0008] The first limiting member and the second limiting member have adjustable connection positions relative to the support member along the first direction.

[0009] In one embodiment, the first limiting member includes two first limiting rods spaced apart in a second direction, and the second limiting member includes two second limiting rods spaced apart in a second direction.

[0010] One end of the first limiting rod is connected to the support member, and the other end is connected to the first pressing wheel; one end of the second limiting rod is connected to the support member, and the other end is connected to the second pressing wheel;

[0011] The second direction is perpendicular to the first direction.

[0012] In one embodiment, the support member is provided with multiple sets of through slots spaced apart along a first direction; each set of through slots includes two through slots spaced apart along a second direction, and the through slots penetrate the support member along a third direction.

[0013] Two first limiting rods can be inserted into two through slots in a set of through slots, and two second limiting rods can be inserted into two through slots in a set of through slots;

[0014] The third direction is perpendicular to both the second and first directions.

[0015] In one embodiment, both the first limiting rod and the second limiting rod are connected to the corresponding through groove via a first fastener;

[0016] The first fastener is connected to the support member, and the end of the first fastener extends into the through groove, pressing the first limiting rod and the second limiting rod against the groove wall of the corresponding through groove.

[0017] In one embodiment, the support includes a support plate, two first support arms spaced apart along a second direction, and two second support arms spaced apart along a second direction. The first and second support arms are located on opposite sides of the support plate along the first direction, and the support plate is used for detachable connection with the angle grinder and the robotic arm.

[0018] The through slots of some through slot groups are located in the first support arm and the second support arm, while the through slots of other through slot groups are located in the support plate.

[0019] In one embodiment, the first limiting rod includes a first sub-rod and a second sub-rod that are angled together and connected to each other;

[0020] The first sub-rod is connected to the support member, and the second sub-rod is connected to the first pressure wheel;

[0021] The second sub-rod has an adjustable connection position relative to the first sub-rod along the first direction.

[0022] In one embodiment, the end of the first sub-rod facing away from the support member is provided with an adjustment groove that extends along a first direction and penetrates the first sub-rod. The side of the second sub-rod facing away from the first pressure wheel is inserted into the adjustment groove. The second sub-rod is connected to the corresponding adjustment groove by a second fastener.

[0023] The second fastener is connected to the first sub-rod, and the end of the second fastener extends into the adjustment groove, pressing the second sub-rod against the groove wall of the corresponding adjustment groove.

[0024] In one embodiment, the auxiliary positioning device further includes an angle adjustment plate and a mill connection plate located within the accommodating space; the angle adjustment plate is connected to the support member, and the mill connection plate is used to connect to the angle grinder;

[0025] The mill connecting plate is detachably connected to the angle adjustment plate, and the connection angle relative to the angle adjustment plate is adjustable.

[0026] In one embodiment, the angle adjustment plate is provided with a first mating hole and a plurality of first adjustment holes that penetrate the angle adjustment plate. The centers of the plurality of first adjustment holes are located on the same circumference, and the circumference is centered on the center of the first mating hole.

[0028] The first mating hole and the second mating hole are detachably connected by a third fastener, and the second adjustment hole is selectively connected to the first adjustment hole by a fourth fastener.

[0029] In one embodiment, the angle between the line connecting the center of the adjacent first adjustment hole and the center of the first mating hole is 15°.

[0030] The beneficial effects of the aforementioned auxiliary positioning device for the angle grinder are as follows:

[0031] Because the first and second limiting members have adjustable connection positions relative to the support member along the first direction, when dealing with products of different specifications and sizes, the relative positions of the first and second limiting members along the first direction can be adjusted by adjusting the relative positions of the first and second limiting members. This, in turn, changes the distance between the first and second pressing rollers along the first direction. Since the first and second pressing rollers are used to roll and abut against different surfaces of the product to be processed, they are applicable to products of different sizes and specifications, making the auxiliary positioning device of the angle grinder more versatile. Furthermore, since there is no need to frequently replace auxiliary positioning devices of different specifications, production costs are reduced. Attached Figure Description

[0054] The auxiliary positioning device 100 (hereinafter also referred to as auxiliary positioning device 100) of the angle grinder according to an embodiment of this application is described below with reference to the accompanying drawings. The angle grinder 40 is used to process the product 70 to be processed. In this application, the product 70 to be processed is a sheet metal box with weld seams as an example for description. The case of other types of products to be processed is similar and will not be described in detail here.

[0055] Figure 1 A schematic diagram of the auxiliary positioning device for an angle grinder provided in an embodiment of this application; Figure 2 A schematic diagram illustrating the usage state of the auxiliary positioning device for an angle grinder provided in an embodiment of this application; Figure 3 Right view of the auxiliary positioning device for an angle grinder provided in an embodiment of this application; Figure 4 This is a front view of the auxiliary positioning device for an angle grinder provided in an embodiment of this application; Figure 5 Left view of the auxiliary positioning device for an angle grinder provided in an embodiment of this application; Figure 6 This is a top view of the auxiliary positioning device for an angle grinder provided in an embodiment of this application.

[0056] Reference Figures 1-6 The auxiliary positioning device 100 provided in this application embodiment includes: a support member 10, a first limiting member 30 and a second limiting member 50, a first pressing wheel 61 and a second pressing wheel 62.

[0057] The support member 10 is detachably connected to the angle grinder 40 and the robotic arm (not shown), respectively. A first limiting member 30 and a second limiting member 50 are connected to the support member 10, and are spaced apart along a first direction F, together with the support member 10 defining a receiving space C for accommodating the angle grinder 40. At least a portion of the angle grinder 40 is housed within the receiving space C.

[0058] The first pressing roller 61 and the second pressing roller 62 are rotatably connected to the first limiting member 30 and the second limiting member 50, respectively. The first pressing roller 61 and the second pressing roller 62 are used to roll and abut against different surfaces of the product 70 to be processed. For example, the first pressing roller 61 can press against the first surface 71, and the second pressing roller 62 can press against the second surface 72. The cutting blade 95 of the angle grinder 40 can process the weld position. The first surface 71 and the second surface 72 can be set perpendicularly.

[0059] The first limiting member 30 and the second limiting member 50 have adjustable connection positions relative to the support member 10 along the first direction F.

[0060] Since the first limiting member 30 and the second limiting member 50 have adjustable connection positions relative to the support member 10 along the first direction F, when facing products 70 of different specifications and sizes, the relative positions of the first limiting member 30 and the support member 10 and the second limiting member 50 and the support member 10 can be adjusted, thereby adjusting the relative positions of the first limiting member 30 and the second limiting member 50 along the first direction F. This causes the distance between the first pressing roller 61 and the second pressing roller 62 along the first direction F to change. Since the first pressing roller 61 and the second pressing roller 62 are used to roll and abut against different surfaces of the product 70, they can be applied to products 70 of different sizes and specifications, making the auxiliary positioning device 100 of the angle grinder more versatile. Since there is no need to frequently replace the auxiliary positioning device 100 of different specifications, this also reduces production costs.

[0061] In addition, when there is a protrusion or depression on a certain position on the surface of the product 70 to be processed, the protrusion or depression can be avoided by changing the fixed position of the first limiting member 30 and the second limiting member 50 on the support member 10, so as not to affect the polishing effect.

[0062] Furthermore, the first limiting member 30 includes two first limiting rods 31 arranged at intervals in the second direction S, and the second limiting member 50 includes two second limiting rods 51 arranged at intervals in the second direction S.

[0063] One end of the first limiting rod 31 is connected to the support member 10, and the other end is connected to the first pressing wheel 61. One end of the second limiting rod 51 is connected to the support member 10, and the other end is connected to the second pressing wheel 62.

[0064] Wherein, the second direction S is perpendicular to the first direction F. For ease of explanation, a third direction T is defined, which is perpendicular to both the second direction S and the first direction F. In specific implementation, the third direction T can be, for example, the thickness direction of the support member 10.

[0065] The two first limiting rods 31 can be connected by a connecting rod 20 extending along the second direction S to enhance the connection strength; or the two second limiting rods 51 can also be connected by a connecting rod 20 extending along the second direction S to enhance the connection strength.

[0066] The number of connecting rods 20 can be set as needed. When there are multiple connecting rods 20, they can be arranged at intervals along the third direction T. It is understood that when the angle grinder 40 is connected to the support member 10, the position of the connecting rods 20 should avoid the position of the angle grinder 40, so as to avoid interference with the angle grinder 40 when the first limiting member 30 and the second limiting member 50 are adjusted in the first direction F.

[0067] In this embodiment, the support member 10 is provided with multiple sets of through slots 11 spaced apart along a first direction F. Each set of through slots 11 includes two through slots 111 spaced apart along a second direction S, and the through slots 111 penetrate the support member 10 along a third direction T. Two first limiting rods 31 can be inserted into two through slots 111 in one set of through slots 11, and two second limiting rods 51 can be inserted into two through slots 111 in one set of through slots 11.

[0068] Since the two first limiting rods 31 can be inserted into the two through slots 111 in a set of through slot groups 11, and the two second limiting rods 51 can be inserted into the two through slots 111 in a set of through slot groups 11, that is, the first limiting member 30 can be positioned with the support member 10 by being installed with the through slots 111 in the through slot group 11, and the second limiting member 50 can also be positioned with the support member 10 by being installed with the through slots 111 in the through slot group 11. Of course, since different through slot groups 11 are arranged at intervals along the first direction F, the first limiting member 30 can change its position relative to the support member 10 along the first direction F as long as it is connected to different through slot groups 11, and the second limiting member 50 can change its position relative to the support member 10 along the first direction F as long as it is connected to different through slot groups 11. In this way, the distance between the first limiting member 30 and the second limiting member 50 along the first direction F can be adjusted.

[0069] Furthermore, both the first limiting rod 31 and the second limiting rod 51 are connected to the corresponding through groove 111 via the first fastener 21. The first fastener 21 is connected to the support member 10, and the end of the first fastener 21 extends into the through groove 111, pressing the first limiting rod 31 and the second limiting member 50 against the groove wall of the corresponding through groove 111.

[0070] In a specific implementation, the cross-sectional shape of the through groove 111 can be square, so that the through groove 111 is formed into a square through groove 111. The extension direction of the first fastener 21 can be perpendicular to the third direction T and along the second direction S. The number of the first fasteners 21 can be one or more, and the first fastener 21 can be a set screw.

[0071] Furthermore, this configuration allows for adjustment of the relative positions of the first limiting rod 31 and the support member 10 along the third direction T, as well as the relative positions of the second limiting rod 51 and the support member 10 along the third direction T. This makes it suitable for processing products 70 of different specifications. For example, when loosening the first fastener 21, the positions of the first limiting rod 31 and the second limiting rod 51 relative to the support member 10 along the third direction T can be adjusted by adjusting their positions within the through groove 111. The through groove 111 can extend along the third direction T.

[0072] Furthermore, the support member 10 includes a support plate 12, two first support arms 13 arranged at intervals along the second direction S, and two second support arms 14 arranged at intervals along the second direction S. The first support arms 13 and the second support arms 14 are respectively located on both sides of the support plate 12 along the first direction F. The support plate 12 is used for detachable connection with the angle grinder 40 and the robotic arm.

[0073] The through slots 111 of part of the through slot group 11 are located in the first support arm 13 and the second support arm 14, while the through slots 111 of another part of the through slot group 11 are located in the support plate 12.

[0074] In a specific implementation, within the through-slot groups 11 located in the first support arm 13 and the second support arm 14, in one portion of the through-slot groups 11, two through-slots 111 of each through-slot group 11 are respectively disposed on the two first support arms 13. In the other portion of the through-slot groups 11, two through-slots 111 of each through-slot group 11 are respectively disposed on the two second support arms 14. In this case, the number of first fasteners 21 corresponding to each through-slot 111 can be two; for example, two first fasteners 21 can be inserted into the through-slot 111 from opposite sides along the second direction S.

[0075] In the through-slot group 11 located on the support plate 12, two through slots 111 of each through-slot group 11 are arranged at the two ends of the support plate 12 along the second direction S. At this time, the number of first fasteners 21 corresponding to each through slot 111 can be one, for example, the first fastener 21 can be inserted into the through slot 111 from the outside edge of the support plate 12.

[0076] In this embodiment, the first limiting rod 31 includes a first sub-rod 311 and a second sub-rod 312 that are angled together and connected to each other. The first sub-rod 311 is connected to the support member 10, and the second sub-rod 312 is connected to the first pressing wheel 61. The second sub-rod 312 has an adjustable connection position relative to the first sub-rod 311 along a first direction F.

[0077] With this configuration, the position of the first pressing wheel 61 relative to the support member 10 in the first direction F can be changed simply by adjusting the connection position of the first sub-rod 311 and the second sub-rod 312 along the first direction F.

[0078] Furthermore, the end of the first sub-rod 311 facing away from the support member 10 is provided with an adjustment groove 3110 extending along the first direction F and penetrating the first sub-rod 311. The side of the second sub-rod 312 facing away from the first pressure wheel 61 is inserted into the adjustment groove 3110. The second sub-rod 312 is connected to the corresponding adjustment groove 3110 through the second fastener 22.

[0079] The second fastener 22 is connected to the first sub-rod 311. The end of the second fastener 22 extends into the adjustment groove 3110 and presses the second sub-rod 312 against the groove wall of the corresponding adjustment groove 3110.

[0080] With this configuration, by loosening the second fastener 22, the second sub-rod 312 can move along the first direction F to adjust the relative position of the second sub-rod 312 and the first sub-rod 311 along the first direction F, thereby adjusting the relative position of the first pressure wheel 61 relative to the support member 10 along the first direction F. The first sub-rod 311 can extend along the third direction T, and the second sub-rod 312 can extend along the first direction F. Of course, a connecting rod 20 can also be connected between the two first sub-rods 311 and between the two second sub-rods 312 to strengthen the structure.

[0081] There are three second fasteners 22. For example, they can be located on both sides of the second direction S of the adjustment groove 3110 and on the third direction T side of the adjustment groove 3110. By using the three second fasteners 22, the second sub-rod 312 and the adjustment groove 3110 can be better fixed relative to each other.

[0082] For the second limit lever 51, refer to Figure 2 For example, it may include a first sub-segment 511, a second sub-segment 512, and a third sub-segment 513 connected in sequence. The first sub-segment 511 and the third sub-segment 513 both extend along a third direction T, while the second sub-segment 512 extends along a first direction F. The first sub-segment 51 is connected to the support member 10, and the second pressure roller 62 can be connected to the third sub-segment 513. In this way, the entire second limiting rod 51 can be formed in the shape of the English letter "Z" to reduce the volume of the entire auxiliary positioning device 100.

[0083] In this embodiment of the application, combined with Figure 3 and Figure 4 The auxiliary positioning device 100 also includes an angle adjustment plate 80 and a mill connection plate 90 located in the accommodating space C. The angle adjustment plate 80 is connected to the support member 10, and the mill connection plate 90 is used to connect to the angle grinder 40.

[0084] The mill connecting plate 90 is detachably connected to the angle adjusting plate 80, and the connection angle relative to the angle adjusting plate 80 is adjustable.

[0085] This setting allows for flexible adjustment of the angle grinder 40 angle according to the condition of the surface to be processed, making it suitable for different grinding processes and thus making the angle grinder 40 more versatile.

[0086] Furthermore, the angle adjustment plate 80 is provided with a first mating hole 81 and a plurality of first adjustment holes 82 penetrating the angle adjustment plate 80. The centers of the plurality of first adjustment holes 82 are located on the same circumference, with the center of the first mating hole 81 as the center of the circumference.

[0087] The mill connecting plate 90 is provided with a second mating hole and a second adjusting hole 92 that penetrate the mill connecting plate 90. The first mating hole 81 and the second mating hole are detachably connected by a third fastener 23, and the second adjusting hole 92 is selectively connected to the first adjusting hole 82 by a fourth fastener 24.

[0088] Thus, when the third fastener 23 connects the second mating hole to the first mating hole 81, and the fourth fastener 24 connects the second adjusting hole 92 to different first adjusting holes 82, the connection angle between the mill connecting plate 90 and the angle adjusting plate 80 can be changed. This changes the connection angle between the angle grinder 40 and the support member 10.

[0089] Furthermore, the angle between the line connecting the center of the adjacent first adjustment hole 82 and the center of the first mating hole 81 is 15°. Thus, when the second adjustment hole 92 is connected to the adjacent first adjustment hole 82, the rotation angle of the angle grinder 40 relative to the support member 10 is 15°.

[0090] Of course, the auxiliary positioning device 100 may also include a mounting cover 93 and an auxiliary connector 94. The mounting cover 93 is used to cover the angle grinder 40 and is connected to the angle grinder 40. One side of the auxiliary connector 94 is connected to the mounting cover 93 and the other side is connected to the grinder connecting plate 90.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
