[0037] Please refer to the following: Figure 1 and Figure 2 The centering device 100 provided in the embodiments of this application will now be described.

[0038] The centering device 100 provided in this application embodiment includes a frame 10, a clamp 20, and a centering assembly 30.

[0039] The fixture 20 is mounted on the frame 10. The fixture 20 has a guide groove 21 that extends along the first direction and passes through the fixture 20. The guide groove 21 is suitable for assembling the workpiece 40.

[0040] like Figure 1 As shown, Figure 1 The x-direction shown is the first direction. Figure 1 The y-direction shown is the second direction. Figure 1 The z-direction shown is the third direction.

[0041] The fixture 20 is located on one side of the frame 10 along the third direction z. The end of the fixture 20 away from the frame 10 is provided with a guide groove 21. The guide groove 21 passes through both ends of the fixture 20 along the first direction x. The workpiece 40 can be slidably assembled in the guide groove 21, that is, both ends of the workpiece 40 along the second direction y can be slidably contacted with both ends of the guide groove 21 along the second direction y, so that the workpiece 40 can slide in the guide groove 21 along the first direction x.

[0042] The centering component 30 is disposed on the frame 10 and includes a first abutting member 31 and a second abutting member 32. The first abutting member 31 and the second abutting member 32 are arranged at intervals along the first direction x, and the guide groove 21 is located between the first abutting member 31 and the second abutting member 32. The first abutting member 31 and the second abutting member 32 can move synchronously towards each other to center the workpiece 40 in the guide groove 21 along the first direction x.

[0043] like Figure 1 As shown, the centering component 30 and the clamp 20 are both located on the same side of the frame 10 along the third direction z. The centering component 30 is provided with a first abutting member 31 and a second abutting member 32. The first abutting member 31 and the second abutting member 32 are arranged along the extension direction of the guide groove 21, and the distance between the end of the first abutting member 31 facing the second abutting member 32 and the guide groove 21 is the same as the distance between the end of the second abutting member 32 facing the first abutting member 31 and the guide groove 21.

[0044] The centering component 30 can drive the first abutment 31 and the second abutment 32 to move synchronously towards each other or synchronously away from each other. That is, the moving speed of the first abutment 31 in the first direction x is the same as the moving speed of the second abutment 32 in the first direction x, and the moving direction of the first abutment 31 in the first direction x is always opposite to the moving direction of the second abutment 32 in the first direction x. This ensures that the distance between the end of the first abutment 31 facing the second abutment 32 and the guide groove 21 and the distance between the end of the second abutment 32 facing the first abutment 31 and the guide groove 21 are always the same.

[0045] Therefore, when the first abutting member 31 and the second abutting member 32 move toward each other, if the workpiece 40 is not located in the center of the first direction x of the fixture 20, one of the first abutting member 31 and the second abutting member 32 can push against one end of the workpiece 40 until the other end of the workpiece 40 abuts against the other of the first abutting member 31 and the second abutting member 32.

[0046] The end of the first abutment 31 facing the second abutment 32 and the end of the second abutment 32 facing the first abutment 31 move synchronously towards each other, so that the midpoint position of the end of the first abutment 31 and the end of the second abutment 32 remains unchanged. The workpiece 40 is clamped by the first abutment 31 and the second abutment 32 in the first direction x, so that the midpoint of the workpiece 40 in the first direction x coincides with the midpoint of the end of the first abutment 31 and the end of the second abutment 32 in the first direction x, thereby realizing the centering operation of the workpiece 40 in the first direction x.

[0047] The beneficial effects of the centering device 100 provided in this application are as follows: The centering device 100 provided in this application can be used to clamp and position the electrode before EDM machining. The centering device 100 provided in this application moves the first abutting member 31 and the second abutting member 32 towards each other until the first abutting member 31 and the second abutting member 32 respectively abut against the two ends of the workpiece 40 assembled in the guide groove 21 along the first direction x, so that the midpoint of the workpiece 40 in the first direction x is located at the midpoint of the end of the first abutting member 31 and the end of the second abutting member 32, thereby realizing a semi-automatic centering operation. The centering device 100 provided in this application does not require manual measurement by the operator, so the centering device 100 provided in this application has the advantages of high centering efficiency and high centering accuracy, and solves the technical problems of low efficiency and low centering accuracy of manual electrode centering operation in related technologies.

[0048] In some embodiments provided in this application, the centering component 30 includes a first rack 33, a second rack 34, and a gear 35. The gear 35 is rotatably mounted on the frame 10. The first rack 33 and the second rack 34 are both movably mounted on the frame 10 along a first direction x. The first rack 33 is connected to a first abutment member 31, and the second rack 34 is connected to a second abutment member 32. The first rack 33 and the second rack 34 are respectively located on opposite sides of the gear 35 along a second direction y. The gear 35 is simultaneously connected to the first rack 33 and the second rack 34 in a transmission connection. The second direction y is orthogonal to the first direction x.

[0049] like Figure 2 and Figure 3 As shown, the axis of gear 35 extends along a third direction z, and the first rack 33 and the second rack 34 both extend along a first direction x. The first rack 33, gear 35 and the second rack 34 are arranged sequentially along a second direction y. The first rack 33 and the second rack 34 mesh with gear 35. Thus, when gear 35 rotates in any direction, the first rack 33 and the second rack 34 move in opposite directions in the first direction x. The tooth pitch of the first rack 33 and the second rack 34 is the same. Thus, when gear 35 rotates around its axis, the first rack 33 and the second rack 34 move at the same speed.

[0050] The first abutment 31 is connected to the end of the first rack 33 away from the second rack 34 along the first direction x, and the second abutment 32 is connected to the end of the second rack 34 away from the first rack 33 along the first direction x. The first abutment 31 is located on the side of the first rack 33 facing the second rack 34 along the second direction y, and the second abutment 32 is located on the side of the second rack 34 facing the first rack 33 along the second direction y, so that the first abutment 31 and the second abutment 32 are arranged opposite to each other along the first direction x.

[0051] Therefore, by engaging the gears 35, the first rack 33 and the second rack 34 are driven to move synchronously towards each other, thereby driving the first abutting member 31 and the second abutting member 32 to move synchronously towards each other. On the one hand, this makes the centering assembly 30 more compact and reduces its size. On the other hand, the gears 35 are connected to the first rack 33 and the second rack 34 by engaging, which improves the motion accuracy. As a result, the centering device 100 provided in this application has a higher centering accuracy.

[0052] In some embodiments provided in this application, the centering device 100 further includes a drive member 70, the fixed end of the drive member 70 is disposed on the frame 10, and the drive end of the drive member 70 is connected to the first rack 33 to drive the first rack 33 to move along the first direction x.

[0053] like Figure 2 As shown, the driving component 70 can be a linear drive element such as a linear cylinder or a linear motor. The driving component 70 extends along the first direction x so that the driving end of the driving component 70 can move relative to the fixed end of the driving component 70 along the first direction x. Thus, the driving component 70 drives the first rack 33 to move along the first direction x. While the first rack 33 moves along the first direction x, the first rack 33 drives the gear 35 to rotate. The gear 35 drives the second rack 34 to move in the opposite direction to the first rack 33. In turn, the driving component 70 drives the first abutment 31 and the second abutment 32 to move synchronously towards each other or away from each other along the first direction x.

[0054] Therefore, by driving the first abutting member 31 and the second abutting member 32 to move through the driving member 70, the centering efficiency of the centering device 100 provided in this application can be improved compared with manual operation, and the centering accuracy of the centering device 100 provided in this application can be improved compared with manual operation.

[0055] In some embodiments provided in this application, the centering device 100 further includes a control element 80, which is connected to the drive element 70 to control the drive element 70.

[0056] like Figure 2As shown, the control component 80 can be a manual valve, button, or other control element. The control component 80 is connected to the drive component 70. The control component 80 controls the movement direction and stroke of the drive end of the drive component 70 in the first direction x, thereby realizing manual control of the movement direction of the first abutment 31 and the second abutment 32.

[0057] Therefore, the operator can control the movement of the drive component 70 through the control component 80, and control the movement direction of the first abutment component 31 and the second abutment component 32 through the control component 80. Thus, the centering device 100 provided in this application can realize semi-automatic centering operation on the workpiece 40. On the one hand, it improves the accuracy and efficiency of centering operation on the workpiece 40 compared with manual operation. On the other hand, compared with the fully automatic centering device 100, it retains some manual actions, which improves the safety and controllability of centering operation.

[0058] In some embodiments provided in this application, the centering device 100 further includes a base 60, which is disposed on the frame 10. The distance between the first abutment 31 and the base 60 is the same as the distance between the second abutment 32 and the base 60. There are multiple clamps 20, and the guide grooves 21 of the multiple clamps 20 have different shapes. The clamps 20 are detachably connected to the base 60 so that the centering device 100 can be compatible with workpieces 40 of different shapes.

[0059] Since the distance between the end of the first abutment 31 facing the second abutment 32 and the guide groove 21 and the distance between the end of the second abutment 32 facing the first abutment 31 and the guide groove 21 are always the same, when the distance between the two ends of the workpiece 40 along the first direction x and the midpoint between the end of the first abutment 31 and the end of the second abutment 32 is the same, the midpoint between the end of the workpiece 40 and the end of the second abutment 31 along the first direction x is achieved.

[0060] like Figure 2 As shown, the frame 10, base 60, and fixture 20 are arranged sequentially along the third direction z. The base 60 is fixedly connected to the frame 10, and the fixture 20 is detachably mounted on the base 60. The distance between the first abutment 31 and the base 60 is the same as the distance between the second abutment 32 and the base 60. When the workpiece 40 is centered in the first direction x, the workpiece 40 is located on the side of the base 60 away from the frame 10 along the third direction z. This allows the workpiece 40 to be located in the guide groove 21 of the fixture 20, preventing the workpiece 40 from falling out of the positioning groove when centered in the first direction x.

[0061] The fixture 20 is detachably connected to the base 60 so as to facilitate quick replacement of the fixture 20 on the base 60. The guide groove 21 in different fixtures 20 has a different cross-sectional shape in the yOz plane. By replacing different fixtures 20, the centering device 100 provided in this application can achieve compatibility with workpieces 40 of various shapes.

[0062] Thus, the fixture 20 is detachably connected to the base 60, which on the one hand facilitates the replacement of fixtures 20 with different shapes, so that the centering device 100 provided in this application can be compatible with workpieces 40 of various shapes. On the other hand, when the workpiece 40 is centered and positioned in the fixture 20, the fixture 20 and the workpiece 40 can be quickly disassembled.

[0063] In some embodiments provided in this application, the fixture 20 is provided with at least one through hole 22, which extends along the second direction y and passes through one inner wall of the guide groove 21 in the second direction y and one end of the fixture 20 in the second direction y. The through hole 22 is provided with an internal thread. The centering device 100 also includes a clamping member, which can be threaded into the through hole 22, and the end of the clamping member can extend into the guide groove 21 so that the workpiece 40 to be processed is supported against the other inner wall of the guide groove 21 in the second direction y by the clamping member, so as to fix the workpiece 40 that has been centered and positioned in the fixture 20.

[0064] Therefore, by disassembling the fixture 20 from the base 60, the workpiece 40 can be disassembled from the base 60 while maintaining a fixed relative position with the fixture 20, so that the fixture 20 together with the workpiece 40 can be moved to the processing equipment for processing.

[0065] In some embodiments provided in this application, at least one of the base 60 and the clamp 20 is provided with a magnetic element so that the base 60 and the clamp 20 can be magnetically connected.

[0066] like Figure 2 and Figure 3 As shown, the end of the base 60 facing the clamp 20 is provided with a magnetic element. The clamp 20 is made of ferromagnetic materials such as iron, cobalt, and nickel, so that the clamp 20 can be attracted by the magnetic element on the base 60. On the one hand, this facilitates the removal of the clamp 20 from the base 60, thereby improving the centering efficiency of the centering device 100 provided in this application; on the other hand, it can prevent the clamp 20 from shaking when the workpiece 40 is pushed by the first abutment 31 or the second abutment 32, thereby improving the centering accuracy of the centering device 100 provided in this application.

[0067] In some embodiments provided in this application, the base 60 is provided with a plurality of first positioning holes 61 at the end facing the positioning seat, there are a plurality of magnetic elements, and the magnetic elements are respectively provided on the hole wall of the first positioning hole 61. The clamp 20 is provided with a plurality of positioning blocks 23, which can be respectively fitted into the first positioning hole 61 and magnetically connected to the magnetic elements.

[0068] like Figure 3 As shown, a magnetic component is disposed on the wall of the first positioning hole 61, and at least two first positioning holes 61 are arranged along the first direction x and at least two first positioning holes 61 are arranged along the second direction y, so that when multiple positioning blocks 23 are matched one-to-one with multiple first positioning holes 61, multiple positioning points are arranged along the first direction x and along the second direction y, thereby restricting the degrees of freedom of the clamp 20 in the first direction x and the second direction y to improve the positioning accuracy of the clamp 20 assembled on the base 60, thereby improving the alignment accuracy of the alignment device 100 provided in this application.

[0069] In some embodiments provided in this application, the gear 35 is disposed between the base 60 and the frame 10.

[0070] like Figure 3 As shown, the base 60, gear 35 and frame 10 are arranged sequentially along the third direction z. The axle of gear 35 extends along the third direction z. One end of the axle of gear 35 is rotatably connected to the base 60, and the other end of the axle of gear 35 is rotatably connected to the frame 10.

[0071] Thus, on the one hand, the gear 35 is fixed to the frame 10 by the base 60, and on the other hand, the base 60 blocks the part where the gear 35 meshes with the first rack 33 in the third direction z, and also blocks the part where the gear 35 meshes with the second rack 34 in the third direction z. This prevents foreign objects from entering the meshing part of the gear 35 and the first rack 33, and also prevents foreign objects from entering the meshing part of the gear 35 and the second rack 34, thereby improving the transmission accuracy between the first rack 33 and the gear 35, and improving the transmission accuracy between the gear 35 and the second rack 34, thereby improving the alignment accuracy of the alignment device 100 provided in this application.

[0072] In some embodiments provided in this application, either the base 60 or the clamp 20 is provided with a positioning pin 62, and the other of the base 60 and the clamp 20 is provided with a second positioning hole 24. The positioning pin 62 can be assembled into the second positioning hole 24, and when the positioning pin 62 is assembled into the second positioning hole 24, both the positioning pin 62 and the second positioning hole 24 extend along the axial direction of the gear 35.

[0073] like Figure 3 , Figure 4 and Figure 5As shown, the end of the base 60 facing the clamp 20 is provided with a positioning pin 62. The positioning pin 62 protrudes along the third direction z. The clamp 20 is provided with a second positioning hole 24. The positioning pin 62 can be fitted into the second positioning hole 24 to position and connect the clamp 20 and the base 60.

[0074] Thus, by engaging the positioning pin 62 into the second positioning hole 24 and engaging the positioning block 23 into the first positioning hole 61, the clamp 20 is installed on the base 60 in a fixed posture, thereby improving the positioning accuracy of the clamp 20 relative to the base 60 and thus improving the centering accuracy of the centering device 100 provided in this application.

[0075] In some embodiments provided in this application, the second positioning hole 24 is located at the center of the clamp 20 in both the first direction x and the second direction y. The axle of the gear 35 and the second positioning hole 24 both extend in the third direction z, and the axle of the gear 35 and the second positioning hole 24 extend coaxially, that is, the axis of the gear 35 coincides with the axis of the second positioning hole 24, ensuring that the clamp 20 and the gear 35 are concentric, and the distance between the first abutment 31 and the clamp 20 and the distance between the second abutment 32 and the clamp 20 are always the same, thereby ensuring the alignment accuracy of the alignment device 100 provided in this application.

[0076] In some embodiments provided in this application, the centering device 100 further includes a first guide rail 91 and a second guide rail 92 disposed on the frame 10. Both the first guide rail 91 and the second guide rail 92 extend along a first direction x. A first rack 33 is slidably mounted on the first guide rail 91, and a second rack 34 is slidably mounted on the second guide rail 92.

[0077] like Figure 2 As shown, the first guide rail 91 and the second guide rail 92 are linear guide rails, and both the first guide rail 91 and the second guide rail 92 are fixed to the frame 10. The first rack 33 can slide along the first guide rail 91, and the second rack 34 can slide along the second guide rail 92. Thus, by setting the first guide rail 91 and the second guide rail 92, the guiding accuracy of the first rack 33 and the second rack 34 in the first direction x is improved, thereby improving the alignment accuracy of the alignment device 100 provided in this application.

[0078] In some embodiments provided in this application, such as Figure 1 As shown, the centering device 100 also includes a housing 50, which is disposed on the frame 10 and has an inner cavity. The first rack 33, the second rack 34 and the gear 35 are all located in the inner cavity. The housing 50 has a first opening 51 and a second opening 52. The first opening 51 penetrates the inner cavity and the outer side of the housing 50 along a third direction z, and the first opening 51 extends along a first direction x. The first abutment 31, the second abutment 32 and the clamp 20 are disposed on the outer side of the first opening 51. The base 60 is disposed on the first opening 51, and at least part of the control member 80 extends to the outer side of the second opening 52.

[0079] Therefore, by setting the housing 50, only part of the base 60, clamp 20, part of the centering component 30 and part of the control component 80 are exposed on the outside of the housing 50. On the one hand, the centering device 100 provided in this application has a simple and beautiful appearance. On the other hand, the housing 50 can protect other components inside the housing 50.

[0080] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
