Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, in particular to a cable insulation layer thickness detection device. Background Art

[0002] The insulation layer refers to the insulating material layer between the heating wires or between the heating wires and the grounding shield layer. It is mainly used to isolate the wires to prevent people from getting an electric shock.

[0003] More and more environmental requirements demand that high-voltage cable products have a small outer diameter. An overly thick sheath will increase the laying difficulty. Therefore, the thickness of the sheath is required to strictly meet relevant standards. Otherwise, it cannot play the role of protecting the wires and cables. Of course, resources cannot be wasted by simply pursuing its thickness. Therefore, a detection device for the insulation layer thickness is needed to detect the insulation layer.

[0004] The existing insulation layer thickness detection devices can only detect a certain fixed position of the insulation sample and cannot detect the insulation thickness at multiple positions, resulting in low detection accuracy of the insulation layer thickness.

[0005] Therefore, the cable insulation layer detection devices in the prior art have the technical problem of low detection accuracy. Summary of the Utility Model

[0006] A cable insulation layer thickness detection device provided by the utility model solves the technical problem of low detection accuracy of the cable insulation layer detection devices in the prior art.

[0007] Some implementation schemes for solving the above technical problems include:

[0008] A cable insulation layer thickness detection device includes a frame. The frame is provided with a guide rail, and the frame is also provided with a gripper for clamping the cable;

[0009] There are two grippers. The two grippers are coaxially arranged. Both of the two grippers slide along the guide rail. Moreover, both of the two grippers are provided with sliding grooves that cooperate with the guide rail;

[0010] The frame is also provided with a detection component. The detection component is slidably connected to the frame. The detection component includes a sliding seat. The sliding seat is provided with a groove that cooperates with the guide rail. The sliding seat is provided with an annular track, and a detector is arranged on the annular track;

[0011] The annular track is provided with a notch for the cable to pass through. The detector is slidably arranged on the annular track through the ring rail. The annular track is provided with an annular groove that cooperates with the ring rail. The ring rail is provided with an opening for the cable to pass through;

[0012] The frame is further provided with a driving assembly for driving the two holders to approach or move away from each other simultaneously.

[0013] Preferably, the holder includes a self-centering chuck and a support seat for supporting the self-centering chuck, and the chute is arranged on the support seat.

[0014] Preferably, the driving assembly includes a lead screw rotatably connected to the frame. The two ends of the lead screw are respectively provided with left and right hand threads, and the support seats of the two holders are respectively provided with screw holes matching with the lead screw.

[0015] Preferably, one end of the lead screw is provided with a handle for facilitating the rotation of the lead screw.

[0016] Preferably, the handle is installed on the lead screw by key connection, and the handle is further provided with a rocker, and the rocker is rotatably connected to the handle.

[0017] Preferably, there are two guide rails, and the two guide rails are respectively located on both sides of the lead screw, and the guide rails and the frame are of an integral structure.

[0018] Preferably, the cross-sectional shape of the guide rail is a trapezoid with a wider upper part and a narrower lower part.

[0019] Preferably, the cross-sectional shape of the ring rail is a trapezoid for preventing the ring rail from moving along the axial direction of the ring groove.

[0020] Preferably, the annular track and the sliding seat are of an integral structure.

[0021] Preferably, the ring rail is coaxially arranged with the holder.

[0022] Compared with the prior art, the utility model has the following advantages:

[0023] By providing a sliding seat, the detector is arranged on the sliding seat, and the sliding seat can slide along the guide rail. During the detection process, by moving the sliding seat, the detector can contact different positions of the cable, so that multiple positions of the cable can be detected, improving the detection accuracy. And since the sliding seat slides along the track, only by sliding the sliding seat can different positions of the cable be detected, thus improving the detection efficiency.

[0024] By providing holders, and the two holders are coaxially arranged, the two holders can fix the cable at a position parallel to the guide rail, so that the position of the detector relative to the cable remains unchanged during the sliding process. Therefore, when detecting different positions of the cable, it is not necessary to adjust the position of the detector relative to the cable to complete the detection, further improving the detection efficiency.

[0025] The energy plug is provided with an annular rail and an annular groove, and the detector can slide circumferentially around the cable, so that the insulation layer thickness can be detected at different positions in the circumferential direction of the cable, and more detection data can be obtained, thereby improving the detection accuracy.

The specific embodiments include specific details intended to provide a thorough understanding of the technical solution of the subject matter of the present invention. However, it will be clear and obvious to those skilled in the art that the technical solution of the subject matter of the present invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0037] It will be understood that, in this text, relational terms such as "first" and "second" are intended to distinguish one entity or operation from another entity or operation, and are not intended to imply any actual relationship or order between these entities or operations.

[0038] The term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.

[0039] Referring Figures 1 to 5 As shown, a cable insulation layer thickness detection device includes a frame 1, the frame 1 is provided with a guide rail 11, and the frame 1 is further provided with a gripper 2 for gripping the cable;

[0040] There are two grippers 2, the two grippers 2 are coaxially arranged, both of the two grippers 2 slide along the guide rail 11, and both of the two grippers 2 are provided with sliding grooves cooperating with the guide rail 11;

[0041] The frame 1 is further provided with a detection assembly 3, the detection assembly 3 is slidably connected to the frame 1, the detection assembly 3 includes a slide base 31, the slide base 31 is provided with a groove body cooperating with the guide rail 11, the slide base 31 is provided with an annular track 32, and a detector 332 is arranged on the annular track 32;

[0042] The annular track 32 is provided with a notch 321 for the cable to pass through, the detector 332 is slidably arranged on the annular track 32 through a ring rail 33, the annular track 32 is provided with a ring groove 322 cooperating with the ring rail 33, and the ring rail 33 is provided with an opening 331 for the cable to pass through;

[0043] The frame 1 is further provided with a driving assembly for driving the two grippers 2 to approach or move away from each other simultaneously.

[0044] The cable insulation layer thickness detection device disclosed by the present utility model is used to achieve relative detection. That is, before detection, the insulation layers at both ends of the cable sample are peeled off, then, the radius of the cable core is measured, and then the radius of the cable including the insulation layer is measured. The difference between the radius of the cable core and the radius of the cable including the insulation layer is the single-point thickness of the insulation layer, and this measurement first measures the single-point thickness of the insulation layer.

[0045] Then, clamp both ends of the cable sample with the gripper 2 and keep the cable sample in a state parallel to the guide rail 11.

[0046] Finally, adjust the position of the detector 332 so that the detector 332 contacts the cable. Slide the carriage 31 to make the detector 332 contact different positions of the cable, and the thickness of the insulating layer at different positions can be detected.

[0047] During the detection process, the detector 332 can also slide around the annular groove 322 to detect different positions in the circumferential direction of the cable, further improving the detection accuracy.

[0048] The annular rail 33 can be locked to the annular track 32 by screws. For example, the screws can lock the annular rail 33 to the annular track 32 by friction.

[0049] The detector 332 can be a relative detection tool such as a dial indicator. When the carriage 31 slides along the guide rail 11, the detector 332 shows different readings when contacting the cable at different positions. This reading is the degree of change of the current position relative to the single-point thickness, and the sum of this reading and the single-point thickness is the thickness of the insulating layer of the cable at the current position.

[0050] Refer to Figures 1 to 5 As shown, in some embodiments, the gripper 2 includes a self-centering chuck 21 and a support seat 22 for supporting the self-centering chuck 21, and the chute is provided on the support seat 22. The self-centering chuck 21 can be welded to the support seat 22 to make the self-centering chuck 21 have higher position accuracy relative to the guide rail 11.

[0051] The self-centering chuck 21 is a common three-jaw chuck.

[0052] In some embodiments, the driving assembly includes a lead screw 12 rotatably connected to the frame 1. Both ends of the lead screw 12 are provided with left and right hand threads, and the support seats 22 of the two grippers 2 are respectively provided with screw holes matching the lead screw 12.

[0053] One end of the lead screw 12 is provided with a handle 121 for facilitating the rotation of the lead screw 12.

[0054] The handle 121 is installed on the lead screw 12 by key connection. The handle 121 is further provided with a rocker 122, and the rocker 122 is rotatably connected to the handle 121.

[0055] Both ends of the lead screw 12 can be fixed to the frame 1 through seat bodies. Rolling bearings can be provided between the lead screw 12 and the seat bodies. The seat bodies can be fixed to the frame 1 by screws.

[0056] In some embodiments, there are two guide rails 11, and the two guide rails 11 are respectively located on both sides of the lead screw 12. The guide rails 11 and the frame 1 are of an integral structure.

[0057] The cross-sectional shape of the guide rail 11 is a trapezoid with a wider upper part and a narrower lower part.

[0058] The more the number of guide rails 11, the higher the displacement accuracy of the slide 31 and the support. At the same time, the more the number of guide rails 11, the higher the strength of the frame 1, and during long-term use, neither the guide rails 11 nor the frame 1 is likely to deform.

[0059] Refer to Figures 1 to 5 As shown, in some embodiments, the cross-sectional shape of the ring rail 33 is a trapezoid that prevents the ring rail 33 from moving along the axis direction of the ring groove 322.

[0060] The annular track 32 and the slide 31 are of an integral structure.

[0061] The ring rail 33 and the gripper 2 are coaxially arranged.

[0062] Locking screws can be provided on the ring rail 33. The locking screws penetrate through the ring rail 33. By rotating the locking screws until they contact the bottom wall of the ring groove 322, the ring rail 33 can be locked to the annular track 32 for the convenience of detection.

[0063] In some embodiments, after the cable sample is clamped by the two grippers 2, rotate the lead screw 12 to move the two grippers 2 away from each other. When the cable sample is straightened, the cable sample is parallel to the guide rail 11.

[0064] The above introduces the technical solutions of the subject matter of the present invention and corresponding details. It can be understood that the above introduction is only some implementation schemes of the technical solutions of the subject matter of the present invention, and some details can also be omitted during its specific implementation.

[0065] In addition, in some implementation schemes of the above-mentioned utility model, it is possible to combine multiple implementation schemes. Due to space limitations, various combination schemes are not listed one by one.
