[0052] Embodiment: The utility model discloses a copper bar limiting device to fix copper bar (namely target copper bar 0 below) under the test scene of electric control product, realizes the fixation of copper bar through double -sided clamping, realizes the limiting of copper bar, and the double -sided clamping is different from the existing fixed mode, increases the effective area of contact with copper bar, and realizes the dynamic adjustment of clamping area, and is closely combined with the surface of copper bar, avoids the situation of point contact caused by uneven contact surface, reduces the risk of copper bar ablation under the scene of large -current test, specifically, refer to Figure 1 And Figure 2 The copper bar limiting device comprises:
[0053] The first limiting assembly 1 and the second limiting assembly 2 are located on the opposite sides of the target copper bar 0 respectively.
[0054] The first limiting assembly 1 comprises:
[0055] The first sliding base 11 is used for sliding towards the direction close to / away from the target copper bar 0.
[0056] The first support 12 is connected on the first sliding base 11 through the first adjusting part 14.
[0057] The first clamping part 13 is located at one end of the first support 12 away from the first sliding base 11.
[0058] The second limiting assembly 2 comprises:
[0059] The second sliding base 21 is arranged opposite to the first sliding base 11 and is used for sliding towards the direction close to / away from the target copper bar 0.
[0060] The second support 22 is connected on the second sliding base 21 through the second adjusting part 24 and is opposite to the first support 12.
[0061] The second clamping part 23 is located at one end of the second support 22 away from the second sliding base 21 and opposite the first clamping part 13.
[0062] The first clamping part 13 and the second clamping part 23 form a clamping area acting on the end of the target copper bar 0.
[0063] The first support 12 and the second support 22 are connected by a connecting piece 3.
[0064] The clamping area is dynamically adjusted by the connecting piece 3, the first adjusting piece 14, and the second adjusting piece 24, so that the target copper bar 0 is tightly limited in the clamping area.
[0065] In the embodiment, the first limiting assembly 1 and the second limiting assembly 2 are oppositely arranged to clamp the target copper bar 0 therebetween. Specifically, the first sliding base 11 and the second sliding base 21 can be driven by a driving mechanism to slide towards / away from the target copper bar 0. The driving mechanism can be a gas cylinder or other existing device that can achieve sliding.
[0066] It should be noted that the first sliding base 11 and the second sliding base 21 can achieve a large range of displacement, while the first adjusting piece 14 / second adjusting piece 24 achieves the displacement and / or inclination of the first support 12 / second support 22 relative to the first sliding base 11 / second sliding base 21. In application, first, the first limiting assembly 1 and the second limiting assembly 2 are moved to the corresponding position by the first sliding base 11 and the second sliding base 21, and then the clamping area is adjusted by the first adjusting piece 14 and the second adjusting piece 24 in cooperation with the connecting piece 3 to fix the target copper bar 0.
[0067] As an explanation, the tight limitation means that the target copper bar 0 is fixed between the first clamping part 13 and the second clamping part 23 and cannot move. It can also be understood that the two sides of the copper bar are tightly fitted / abutted with the side surfaces of the first clamping part 13 and the second clamping part 23, respectively. Thus, the contact between the copper bar and the limiting tool is a large area contact, and the double-clamping manner eliminates the gap between the side surface of the copper bar and the side surface of the first clamping part 13 / second clamping part 23, thereby avoiding point contact between the copper bar and the tool and reducing the risk of copper bar ablation in the scenario of large current test.
[0068] In the embodiment, the clamping area is formed by the two opposite sides of the first clamping part 13 and the second clamping part 23, and the target copper bar 0 is tightly limited in the clamping area, the copper bar side is tightly combined with the side of the first clamping part 13 and the second clamping part 23, and the current on the copper bar can be guided to flow through the first clamping part 13 and the second clamping part, and then connected to other devices or apparatuses in the test scene, so that the first clamping part 13 and the second clamping part 23 are made of metal material, so that the current flow area is larger, and the situation that the heat generated in the large current test scene is too large is reduced.
[0069] It can be understood that the connecting part is used to connect the first support 12 and the second support 22, and can realize the adjustment of the clamping area, so that the connecting part can be provided as a telescopic adjustment structure, that is, one end of the telescopic structure is connected to the first clamping part 13 on the first support 12, and the other end is connected to the second clamping part 23 on the second support 22, so that the adjustment structure that can be applied to the test scene without affecting the test process can be used.
[0070] Based on the above, in a preferred embodiment, the connecting part 3 includes a screw rod 31 and a nut 32; the nut 32 is located on the second clamping part 23; the screw rod 31 is connected to the first clamping part 13, the target copper bar 0 and the nut 32 in sequence. That is, the screw rod 31 can be moved towards the nut 32 by rotating the screw rod 31, and when the screw rod 31 is moved towards the nut 32, that is, the first clamping part 13 is moved towards the second clamping part 23, thereby driving the first clamping part 13 to move / tilt towards the second clamping part 23. After the screw rod 31 cooperates with the nut 32, continue to rotate the screw rod 31, then the second clamping part 23 will also move / tilt towards the first clamping part 13, thereby the gap between the first clamping part 13 and the second clamping part 23 gradually decreases, that is, the above-mentioned clamping area gradually decreases, until it is tightly matched with the copper bar.
[0071] It can be understood that the target copper bar 0 is often pre-provided with a connecting hole, so that the screw rod 31 can be connected to the first clamping part 13, the target copper bar 0 and the nut 32 in sequence, that is, as an example, the screw rod 31 can be threadedly connected with the first clamping part 13, and then threadedly connected with the nut 32 through the target copper bar 0, so as to realize the adjustment of the above-mentioned clamping area.
[0072] In a preferred embodiment, the first clamping part 13 is provided with a first through hole 131 for movably connecting the screw rod 31; the second clamping part 23 is provided with a second through hole 231 for fixing the nut 32; the first through hole 131, the second through hole 231 and the connecting hole pre-provided on the target copper bar 0 are located on the same horizontal straight line.
[0073] The above movable connection enables the screw rod 31 to rotate and move forward in the first through hole 131, but at the same time, the screw rod 31 is connected with the first through hole 131, that is, the screw rod 31 is not completely separated from the first through hole 131, so that the relative movement between the first clamping part 13 and the second clamping part 23 is realized by the screw rod 31. It can be understood that the axis of the connection hole pre-set on the target copper bar 0 is located on the same horizontal straight line as the first through hole 131 and the second through hole 231, that is, the screw rod 31 moves horizontally to realize the connection of the first clamping part 13, the target copper bar 0 and the second clamping part 23, thereby improving the connection stability.
[0074] Based on the above, in order to realize the above movable connection, the screw rod 31 is provided with a pressure receiving part 311 away from the end connected with the nut 32, the pressure receiving part 311 extends outward from the screw rod 31; the first through hole 131 is further provided with a stop washer 4; the screw rod 31 is provided with a first spring 5 outside the screw rod 31, and the stop washer 4 is located on the side of the second through hole 231 in the first through hole 131; the first through hole 131 is radially extended inward at the end close to the second through hole 231 to form a blocking area 6, so that the first spring 5 is limited between the blocking area 6 and the pressure receiving part 311; the stop washer 4 is provided with a third through hole 41 through which a pressing tool acting on the pressure receiving part 311 passes.
[0075] In the embodiment, the screw rod 31 is movably connected with the first through hole 131 by the first spring 5 and the stop washer 4. It should be noted that the screw rod 31 and the first spring 5 do not have any connection points with the first through hole 131, but are limited between the blocking area 6 and the pressure receiving part 311 by the first spring 5. The stop washer 4 is arranged on the other side of the pressure receiving part 311, so that the first spring 5 is actually limited between the blocking area 6 (the end of the first through hole 131) and the stop washer 4. The screw rod 31 does not completely separate from the first spring 5 due to the presence of the pressure receiving part 311. Therefore, the screw rod 31 only moves in the first through hole 131 and on the side of the second through hole 231 towards the stop washer 4, and does not completely move out of the first through hole 131. When the first spring 5 is compressed to the maximum, if the screw rod 31 continues to move towards the second through hole 231, the first clamping part 13 will also move / tilt towards the second clamping part 23. The screw rod 31 is provided with the pressure receiving part 311. By means of an external pressing tool entering the first through hole 131 to press the pressure receiving part 311, the screw rod 31 rotates and moves towards the second through hole 231, so as to realize the connection of the screw rod 31 with the nut 32 through the target copper bar 0.
[0076] Specifically, in the initial state, the first spring 5 is in a natural state, and the screw rod 31 is located in the first through hole 131 (not passing through the target copper bar 0). When it is necessary to connect the target copper bar 0 for testing, the pressure bearing part 311 is rotated and moved towards the target copper bar 0 by the pressing tool, the first spring 5 is compressed, the screw rod 31 continues to move out of the first through hole 131, passes through the target copper bar 0 and is connected with the nut 32; by adjusting the connection of the screw rod 31 and the nut 32 to make the first clamping part 13 and the second clamping part 23 move relatively, that is, to adjust the compression strength, the target copper bar 0 is finally tightly limited in the clamping area; when the test is completed, the pressure bearing part 311 is acted on by the pressing tool to make the force-bearing screw rod 31 rotate and separate from the nut 32, and then the first spring 5 returns, thereby driving the screw rod 31 to return to the first through hole 131 (that is, the initial state described above), and due to the existence of the stop washer 4, the force of the first spring 5 during the returning process will not cause the screw rod 31 to move out of the first through hole 131 from the other end.
[0077] Based on the above, as a preferred, the third through hole 41 is coaxial with the first through hole 131, and the inner diameter of the third through hole 41 is smaller than the outer circumference of the pressure bearing part 311. The third through hole 41 is arranged to enable the pressing tool to give the pressure bearing part 311 a certain pressure, so that the screw rod 31 rotates and advances, and thus it is coaxial, so that a horizontal axial pressure can be given to the screw rod 31, thereby facilitating the movement of the screw rod 31. The stop washer 4 is arranged to prevent the force of the first spring 5 during the returning process from causing the screw rod 31 to move out of the first through hole 131 from the other end, and thus the inner diameter of the third through hole 41 is arranged to be smaller than the outer circumference of the pressure bearing part 311.
[0078] Further based on the above, the side of the pressure bearing part 311 away from the screw rod 31 is provided with a pattern matched with the pressing tool, so that the screw rod 31 can be prevented from generating other direction forces when the pressure bearing part 311 is acted on by the pressing tool, thereby affecting the movement of the screw rod 31. Specifically, as an example but not limitation, the screw rod 31 with the pressure bearing part 311 can adopt an existing cross screw, and thus a corresponding screwdriver with a corresponding pattern can be applied to the corresponding pressing work.
[0079] In the embodiment, the clamping area is adjusted by the cooperation degree of the screw rod 31 and the nut 32, that is, as described above, after the screw rod 31 is acted on by the pressing tool on the pressure bearing part 311, the screw rod 31 moves out of the first through hole 131, and after the screw rod 31 is connected with the nut 32, the cooperation degree of the screw rod 31 and the nut 32 can be adjusted by continuing to rotate the screw rod 31, at this time, based on the first adjusting part 14 and the second adjusting part 24, the first clamping part 13 can be driven to move / tilt towards the second clamping part 23, and the second clamping part 23 will also tilt / tilt towards the first clamping part 13, thereby continuously reducing the clamping area, and after the screw rod 31 and the nut 32 are separated from each other, the initial state is restored.
[0080] In the embodiment, as described above, in addition to the connecting part 3, the cooperation of the first adjusting part 14 and the second adjusting part 24 is also needed, and the first adjusting part 14 and the second adjusting part 24 mainly control the movement / tilt of the first support 12 and the second support 22 relative to the first sliding base and the second sliding base, thereby achieving the adjustment of the clamping area at the end of the first support 12 and the second support 22 away from the first sliding base and the second sliding base.
[0081] In a preferred embodiment, the first adjusting part 14 includes a micro-floating platform, which is a mechanical system capable of achieving bidirectional micron or nanometer positioning accuracy in the X-axis and the Y-axis, and can achieve sub-micron to nanometer positioning resolution. In the embodiment, the position of the first support 12 relative to the first sliding base can be accurately adjusted by the micro-floating platform.
[0082] In a preferred embodiment, the second adjusting part 24 includes a second spring 241 and an auxiliary support 242; the auxiliary support 242 includes a first connecting part 2421 and a second connecting part 2422; the first connecting part 2421 is connected to the second sliding base 21 and extends towards the first sliding base 11; the second connecting part 2422 is connected to the first connecting part 2421 away from the side connected to the second sliding base 21; the second connecting part 2422 is connected perpendicularly to the first connecting part 2421 and is parallel to the second support 22; the second spring 241 connects the second connecting part 2422 and the second support 22. Specifically, the first connecting part 2421 and the second connecting part 2422 form an approximately L-shaped design, and the second support 22 forms an approximately U-shaped design, and the second spring 241 is located between the two sides of the U-shaped design, so that the second support 22 is close / tilted to the direction of the second connecting part 2422.
[0083] The second adjusting member 24 can be regarded as achieving the power-free guide rail guiding of the second support 22 on the second sliding base 21. It should be noted that, in order to improve the safety in use, the second support 22 is provided with a certain rigidity, so that when the screw rod 31 cooperates with the nut 32, the second clamping part 23 can move in the direction close to the first clamping part 13 under the force, and the risk of breaking or moving in the opposite direction is reduced.
[0084] It can be understood that when the first limiting assembly 1 and the second limiting assembly 2 are relatively moved by moving the first sliding base 11 and the second sliding base 21, the second connecting part 2422 is preferably located below the side of the copper bar close to the first clamping part 13, so that after the screw rod 31 cooperates with the nut 32, the screw rod 31 continues to rotate, and then the nut 32 drives the second clamping part 23 to move / tilt towards the first clamping part 13. At this time, the second spring 241 can be compressed, and when the test is completed, the screw rod 31 is separated from the nut 32, and then the second spring 241 returns to the original state, which drives the second clamping part 23 to move away from the first clamping part 13.
[0085] In the embodiment, based on the above, the working process is as follows:
[0086] The first support 12 is fixed on the first sliding base 11 and can move back and forth along the X direction shown in the figure under the driving of the air cylinder. The second support 22 is fixed on the second sliding base 21 and can move back and forth along the X direction;
[0087] The limiting process is as follows: the target copper bar 0 is placed in the middle position between the first limiting assembly 1 and the second limiting assembly 2; the first sliding base 11 moves to a certain position along the X+ direction under the driving of the air cylinder; the screw gun is applied to move into the first through hole 131 along the X+ direction, and the locking screw (the screw rod 31 with the pressure bearing part 311) is pushed to contact the locking nut 32 (the nut 32 in the second through hole 231); the screw gun is rotated along the direction of the locking screw, and the locking screw is tightened to the locking nut 32. At this time, due to the tensioning force of the locking nut 32, the second support 22 will move along the X- direction and close to the target copper bar 0; the first support 12 can also move close to the target copper bar 0 due to the arrangement of the micro-floating platform; with the increase of the tightening torque, the clamping area between the first support 12 and the second support 22 is reduced, and the first support 12 and the second support 22 will adaptively adjust the position and tightly fit the side of the target copper bar 0, thereby achieving clamping.
[0088] The releasing process is as follows: the screw gun unscrews the locking screw, the second support 22 is separated from the target copper bar 0 under the action of the second spring 241, and the clamping area returns (increases); after the locking screw and the locking nut 32 are separated, when the screw gun is removed, the locking screw is pushed back into the first support 12 (the first through hole 131) due to the action of the first spring 5; the first sliding base 11 moves along the X-direction under the driving of the air cylinder, and the first support 12 returns to the original position. At this time, the first support 12 and the second support 22 are completely separated from the target copper bar 0.
[0089] Based on the above, the copper bar limiting device provided by the embodiment realizes double-side clamping of the copper bar through the screw rod 31, controls the pressing strength to adjust the clamping area, so that the target copper bar 0 is completely limited in the clamping area, that is, the side surface of the target copper bar 0 is closely attached to the side surface of the first clamping part 13 and the second clamping part 23, thereby increasing the effective contact area, realizing complete clamping of the wire harness and the UVW copper bar in the test scene through the first clamping part 13 and the second clamping part 23, and being easy to realize and applicable to the scene of automatic connection and connected copper bar.
[0090] It can be understood that the copper bar limiting device of the embodiment can include a plurality of first supports 12 and second supports 22 arranged side by side, that is, a plurality of first clamping parts 13 and second clamping parts 23 form a plurality of clamping areas, and each clamping area corresponds to any copper bar element of the target copper bar 0 including a plurality of copper bar elements, thereby being applied to different implementation scenes.
[0091] It should be noted that the embodiments of the utility model have better implementation, and do not limit the utility model in any form, and any skilled person in the art can change or modify the equivalent effective embodiments by using the disclosed technical content, as long as the content does not deviate from the technical scheme of the utility model, and any modification or equivalent change and modification of the above embodiments according to the technical essence of the utility model still belongs to the range of the technical scheme of the utility model.
