Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to an auxiliary positioning clamp. Background Technology

[0002] In machining and assembly, precise workpiece positioning is often required to ensure machining accuracy and assembly quality. Traditional techniques, such as vises, typically fix workpieces by clamping their opposing surfaces. However, as... Figure 1 As shown, for irregularly shaped workpieces with complex shapes, the workpiece can only be positioned by the vertical holes and oblique holes on the same side of the workpiece. The vise is difficult to clamp the irregularly shaped workpiece, which leads to the workpiece being prone to displacement during processing or assembly due to the lack of positioning. This results in a technical problem of low production yield of irregularly shaped workpieces. Utility Model Content

[0003] Therefore, it is necessary to provide an auxiliary positioning fixture to address the technical problem of low production yield of irregularly shaped workpieces.

[0004] An auxiliary positioning fixture is provided for positioning an irregularly shaped workpiece. The irregularly shaped workpiece has a vertical hole and an oblique hole on the same side. The auxiliary positioning fixture includes a fixed platform, a vertical positioning member, an oblique positioning member, a driving assembly, and an elastic assembly. The fixed platform has a flat surface and an inclined surface on the same side. The inclined surface is inclined relative to the flat surface. The flat surface has a first receiving hole corresponding to the position of the vertical hole. The inclined surface has a second receiving hole corresponding to the position of the oblique hole. The vertical positioning member passes through the first receiving hole and can reciprocate along a first direction under the drive of the driving assembly, so that the top end of the vertical positioning member selectively protrudes from the flat surface or is hidden in the first receiving hole. The oblique positioning member passes through the second receiving hole and can move along a second direction under the elastic force of the elastic assembly, so that the top end of the oblique positioning member selectively protrudes from the inclined surface or is hidden in the second receiving hole. The first direction is perpendicular to the flat surface and intersects with the second direction, and the second direction is perpendicular to the oblique surface.

[0005] In one embodiment, the fixed platform includes a flattening part and an inclined part, the flattening part having the flat surface, and the inclined part being disposed on the flat surface and having the inclined surface.

[0006] In one embodiment, there are multiple oblique positioning members, each of which is arranged around the vertical positioning member, and the number of the second receiving holes is the same as the number of oblique positioning members.

[0007] In one embodiment, the drive assembly includes an adapter frame, a drive component, and an adapter plate. The adapter frame is connected to the side of the fixed platform that is away from the flat surface. The drive component is mounted on the adapter frame and drives the adapter plate to move closer to or away from the fixed platform. The adapter plate is connected to the vertical positioning component.

[0008] In one embodiment, the drive assembly further includes a guide rod connected to the fixed platform, and the adapter plate slides along the guide rod.

[0009] In one embodiment, the adapter includes two side plates and a mounting plate. Both side plates are connected to the fixed platform. The two sides of the mounting plate are connected to each of the side plates. The drive component is mounted on the mounting plate.

[0010] In one embodiment, the side plate includes a plate body and a protrusion, the plate body and the protrusion are coplanar and protrude from one side of the plate body, and the fixing platform is provided with a groove that mates with the protrusion.

[0011] In one embodiment, the plate body is provided with a groove, and the mounting plate is inserted into the groove.

[0012] In one embodiment, the elastic component includes a pin barrel and an elastic element. The pin barrel is installed in the second receiving hole and has a sliding hole and a through hole communicating with the sliding hole. The inclined positioning element is slidably connected to the sliding hole and movably passes through the through hole. The elastic element is disposed in the sliding hole and abuts against the inclined positioning element.

[0013] In one embodiment, the side wall of the pin barrel is provided with a positioning surface, and the fixing platform is provided with an auxiliary positioning hole that communicates with the second receiving hole. The auxiliary positioning hole is positioned corresponding to the positioning surface.

[0014] The beneficial effects of the auxiliary positioning fixture provided in this application are as follows: A flat surface and an inclined surface are provided on the same side of the fixed platform. A first receiving hole is recessed in the flat surface, and a second receiving hole is recessed in the inclined surface. A driving assembly allows the top of the vertical positioning member to selectively protrude from the flat surface or be hidden within the first receiving hole along a first direction. An elastic assembly provides the elastic force that allows the inclined positioning member to selectively protrude from the inclined surface or be hidden within the second receiving hole along a second direction. This facilitates control over the vertical hole of the workpiece to engage with the vertical positioning member protruding from the flat surface along the first direction. During the insertion process of the vertical positioning component, the inclined positioning component is squeezed by the workpiece, causing it to be pressed into the second receiving hole until the workpiece is in contact with the flat surface. At this time, the position of the inclined hole of the workpiece corresponds to the inclined positioning component. Under the action of the elastic force of the elastic component, the inclined positioning component is inserted into the inclined hole. The vertical positioning component abuts against the inner wall of the vertical hole of the workpiece, and the inclined positioning component abuts against the inner wall of the inclined hole of the workpiece, preventing the workpiece from moving during processing or assembly. This achieves auxiliary positioning of irregular workpieces and improves the processing quality of irregular workpieces. Attached Figure Description

[0034] like Figures 2 to 5 As shown, this is the auxiliary positioning fixture 100 of this utility model, used for positioning irregularly shaped workpieces 200, such as... Figure 1 As shown, the irregular workpiece 200 has a vertical hole 201 and an oblique hole 202 on the same side.

[0035] like Figures 2 to 3As shown, the auxiliary positioning fixture 100 includes: a fixed platform 10, a vertical positioning member 20, an inclined positioning member 30, a drive assembly 40, and an elastic assembly 50. The fixed platform 10 has a flat surface 11 and an inclined surface 12 on the same side. The inclined surface 12 is inclined relative to the flat surface 11. The flat surface 11 has a recessed first receiving hole 111 corresponding to the position of the vertical hole 201, and the inclined surface 12 has a recessed second receiving hole 121 corresponding to the position of the inclined hole 202. The vertical positioning member 20 passes through the first receiving hole 111 and can reciprocate along a first direction under the drive of the drive assembly 40. The vertical positioning member 20 can be moved such that its top end selectively protrudes from the flat surface 11 or is hidden within the first receiving hole 111. The oblique positioning member 30 passes through the second receiving hole 121 and can move along the second direction under the elastic force of the elastic component 50, such that its top end selectively protrudes from the inclined surface 12 or is hidden within the second receiving hole 121. The first direction is perpendicular to the flat surface 11 and intersects with the second direction, and the second direction is perpendicular to the inclined surface 12. The flat surface 11 and the inclined surface 12 are arranged on the same side of the fixed platform 10, and the first receiving hole is recessed in the flat surface 11. 111, a second receiving hole 121 is recessed at the inclined surface 12. The drive assembly 40 allows the top end of the vertical positioning member 20 to selectively protrude from the flat surface 11 or be hidden within the first receiving hole 111 along the first direction. The elastic assembly 50 provides elastic force to allow the inclined positioning member 30 to selectively protrude from the inclined surface 12 or be hidden within the second receiving hole 121 along the second direction. This facilitates control of the vertical hole 201 of the workpiece to engage with the vertical positioning member 20 protruding from the flat surface 11 along the first direction. During the engagement of the workpiece with the vertical positioning member 20, the inclined positioning member 30 is compressed by the workpiece. The oblique positioning member 30 is pressed into the second receiving hole 121 until the workpiece is in contact with the flat surface 11. At this time, the position of the oblique hole 202 of the workpiece corresponds to the oblique positioning member 30. Under the action of the elastic force of the elastic component 50, the oblique positioning member 30 is inserted into the oblique hole 202. The vertical positioning member 20 abuts against the inner wall of the vertical hole 201 of the workpiece, and the oblique positioning member 30 abuts against the inner wall of the oblique hole 202 of the workpiece, preventing the workpiece from moving during processing or assembly. This achieves auxiliary positioning of the irregular workpiece 200 and improves the processing quality of the irregular workpiece 200.

[0036] The following text, combined with Figures 2 to 5 The auxiliary positioning fixture 100 described above will be further explained.

[0037] like Figures 2 to 3 As shown, the fixed platform 10 includes a flattening part 13 and an inclined part 14. The flattening part 13 has a flat surface 11, and the inclined part 14 is disposed on the flat surface 11 and has an inclined surface 12. There are multiple inclined positioning members 30, and each inclined positioning member 30 is disposed around the vertical positioning member 20. The number of second receiving holes 121 is the same as the number of inclined positioning members 30.

[0038] To improve the lifespan of the drive component 40, such as Figure 3 As shown, the drive assembly 40 includes an adapter frame 41, a drive component 42, and an adapter plate 43. The adapter frame 41 is connected to the side of the fixed platform 10 facing away from the flat surface 11. The drive component 42 is mounted on the adapter frame 41 and drives the adapter plate 43 to move closer to or away from the fixed platform 10. The adapter plate 43 is connected to the vertical positioning component 20. The drive component 42 is a cylinder. The adapter frame 41 connects the drive component 42 to the fixed platform 10, making the installation of the drive component 42 more stable. Furthermore, the drive assembly 40 also includes a guide... The guide rod 44 is connected to the fixed platform 10. The adapter plate 43 slides along the guide rod 44. The guide rod 44 provides guidance for the movement of the adapter plate 43, preventing the adapter plate 43 from shifting or shaking during movement. This ensures that the vertical positioning component 20 can move in the correct direction, further improving the positioning accuracy of the vertical positioning component 20 for the workpiece. In addition, the guide rod 44 can also enhance the overall structural strength of the drive assembly 40, thereby increasing the service life of the drive assembly 40.

[0039] To ensure the stability of the connection between the adapter frame 41 and the fixed platform 10, such as Figure 3 As shown, the adapter frame 41 includes two side plates 411 and a mounting plate 412. Both side plates 411 are connected to the fixed platform 10. The two sides of the mounting plate 412 are connected to the side plates 411. The driving component 42 is mounted on the mounting plate 412. By using two side plates 411 connected to the fixed platform 10 and the mounting plate 412 connected to the side plates 411 and used to mount the driving component 42, the installation of the adapter frame 41 is more convenient. At the same time, it can effectively disperse the force generated by the driving component 42 during operation, so as to ensure the stability of the connection between the adapter frame 41 and the fixed platform 10.

[0040] To further improve the overall structural strength of the fixture, such as... Figure 3 As shown, the side plate 411 includes a plate body 413 and a protrusion 414. The plate body 413 and the protrusion 414 are coplanar and protrude from one side of the plate body 413. The fixing table 10 is provided with a groove 131 that mates with the protrusion 414. Through the mate between the protrusion 414 and the groove 131, the side plate 411 and the fixing table 10 are accurately positioned and quickly installed, which improves the assembly efficiency of the fixture. At the same time, the mate between the protrusion 414 and the groove 131 can also enhance the connection strength between the side plate 411 and the fixing table 10, prevent the side plate 411 from loosening during use, and achieve the purpose of improving the overall structural strength of the fixture.

[0041] To improve the positioning accuracy of the fixture, such as Figure 3As shown, the plate 413 is provided with a groove 415, and the mounting plate 412 is inserted into the groove 415. The groove 415 makes the connection between the mounting plate 412 and the side plate 411 tighter and more stable, which can effectively prevent the mounting plate 412 from shifting during operation. At the same time, the insertion method can improve the installation accuracy of the mounting plate 412, thereby increasing the installation accuracy of the drive component 42, and achieving the purpose of improving the positioning accuracy of the fixture.

[0042] like Figure 4 As shown, the elastic component 50 includes a pin barrel 51 and an elastic element 52. The pin barrel 51 is installed in the second receiving hole 121 and has a sliding hole 511 and a through hole 512 communicating with the sliding hole 511. The inclined positioning element 30 is slidably connected to the sliding hole 511 and movably passes through the through hole 512. The elastic element 52 is disposed in the sliding hole 511 and abuts against the inclined positioning element 30. The inclined positioning element 30 includes a slider 31 and a positioning block 32. The slider 31 is slidably connected to the sliding hole 511, and the positioning block 32 movably passes through the through hole 512 and is inserted into the inclined hole 202.

[0043] To improve the positioning accuracy of the oblique positioning component 30 for workpieces, such as Figure 3 As shown, the side wall of the pin barrel 51 is provided with a positioning surface 513, and the fixed platform 10 is provided with an auxiliary positioning hole 141 that communicates with the second receiving hole 121. The auxiliary positioning hole 141 is positioned corresponding to the positioning surface 513. In use, the pin barrel 51 is fixed in the second receiving hole 121 by threading the set screw into the auxiliary positioning hole 141 and abutting against the positioning surface 513. Through the cooperation between the auxiliary positioning hole 141 and the positioning surface 513, the installation position of the pin barrel 51 in the second receiving hole 121 can be accurately controlled, ensuring the installation accuracy of the pin barrel 51 and thus effectively controlling the displacement accuracy of the inclined positioning component 30, thereby improving the positioning accuracy of the inclined positioning component 30 for the workpiece.

[0044] When the auxiliary positioning fixture 100 provided in this application needs to position the workpiece, the driving component 42 of the driving assembly 40 is activated. The driving component 42 drives the adapter plate 43 to approach the fixed table 10, thereby pushing the vertical positioning component 20 upward so that its top end protrudes from the flat surface 11. Then, the workpiece is inserted into the vertical positioning component 20 protruding from the flat surface 11 along the first direction. During the process of the workpiece being inserted into the vertical positioning component 20 along the first direction, the oblique positioning component 30 is squeezed by the workpiece, causing the oblique positioning component 30 to be pressed into the second receiving hole 121. The workpiece is inserted into the flat surface 11 until it is in contact with the flat surface 11. At this time, the position of the inclined hole 202 of the workpiece corresponds to the inclined positioning member 30. Under the action of the elastic force of the elastic component 50, the inclined positioning member 30 is inserted into the inclined hole 202. The vertical positioning member 20 abuts against the inner wall of the vertical hole 201 of the workpiece, and the inclined positioning member 30 abuts against the inner wall of the inclined hole 202 of the workpiece, preventing the workpiece from moving during the processing or assembly process. This achieves auxiliary positioning of the irregular workpiece 200 and ensures that the workpiece will not move or deviate during the processing or assembly process.

[0045] After the workpiece is processed or assembled, the reverse operation drive assembly 40 is used to hide the vertical positioning member 20 in the first receiving hole 111, thereby separating the vertical hole 201 of the workpiece from the vertical positioning member 20. The workpiece is then controlled to move in the opposite direction to the second direction, thereby separating the oblique hole 202 of the second workpiece from the oblique positioning member 30, and thus removing the workpiece from the auxiliary positioning fixture 100.

[0046] 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.

[0047] 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.
