Description

Technical Field

[0001] The utility model relates to the technical field of measuring jigs, in particular to a jig for measuring wire diameters. Background Art

[0002] When using a composite wire diameter measuring jig, a common problem is the dispute over the aperture and OD. The aperture refers to the diameter of the hole in the measuring jig used to measure the composite wire diameter, while the OD refers to the outer diameter of the composite wire. In actual applications, it often happens that the OD is slightly larger than the aperture. In this case, different testers may have disputes over whether to further upgrade to a larger aperture for adaptation.

[0003] Since the current detection mold uses manual pressing to observe whether the wire diameter corresponds to the hole position in the jig, and the manual operation method is difficult to ensure that it remains stable during the measurement process, resulting in no fixed measurement standard for OD detection.

[0004] In order to solve this problem, we propose a wire diameter measurement fixture to ensure the accuracy of the measurement results. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art that the manual operation mode is difficult to ensure stability during the measurement process, resulting in no fixed measurement standard for OD detection, and proposes a wire diameter measuring fixture.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wire diameter measuring jig is designed, comprising a rotatably connected lower seat and an upper seat, wherein a wire groove is provided on the mating surfaces of the lower seat and the upper seat, and two opposite wire grooves form a wire hole;

[0008] Wherein, a magnetic attraction component and an indication component are arranged on the mating surfaces of the lower seat body and the upper seat body, the two magnetic attraction components are magnetically attracted to each other, and the indication component is used to indicate the attraction state.

[0009] Furthermore, the magnetic attraction assembly includes a fixing member and a magnetic member, and the fixing member and the magnetic member are detachably connected;

[0010] Mounting grooves are provided on the mating surfaces of the lower seat body and the upper seat body, and the fixing member is mounted in the mounting grooves.

[0011] Furthermore, the fixing member includes a connecting bottom surface and a plurality of claws circumferentially distributed on the connecting bottom surface, an annular groove is provided on the outer side of the magnetic member, and claw ends of the plurality of claws are clamped in the annular groove.

[0012] Furthermore, a guide block is fixed on the outer wall of at least one of the claws, and a guide groove matched with the guide block is opened on the inner side of the mounting groove.

[0013] Furthermore, the fixing member also includes a connecting pipe fixed below the connecting bottom surface, and the lower seat body and the upper seat body are provided with grooves below the mounting groove, a screw is rotatably connected in the groove, and the screw is threadedly connected to the connecting pipe.

[0014] Furthermore, one end of the screw rod passes through the interior of the installation groove and is limited by a retaining spring, and a spring is also provided between the connecting pipe and the installation groove.

[0015] Furthermore, the indicating assembly includes a protruding block fixed on the lower seat body, and an adapting groove opened on the side of the upper seat body, the outer sides of the protruding block and the adapting groove both have indicating scales, and the inner side of the adapting groove is also provided with an avoidance groove.

[0016] The utility model proposes a jig for measuring wire diameter, which has the beneficial effect that: in the utility model, magnetic suction components are installed on the opposite surfaces of the lower seat body and the upper seat body. During the test, if the wire pushes the jig open because the OD is too large, it means that the force is too large, and the wire diameter should be upgraded to the aperture measurement of the next larger OD until the wire can pass through with resistance but does not push the magnetic part open. In addition, an indicating scale is designed to intuitively observe the attraction between the upper seat body and the lower seat body. When the two indicating scales are in a straight line during attraction, it indicates complete attraction. On the contrary, when the two indicating scales are misaligned, it can represent that the current wire OD is too large. The overall structural design is simple and reasonable, and the applicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 An embodiment of the utility model discloses a jig for measuring wire diameter, the jig comprises a lower seat body 1 and an upper seat body 2 which are rotatably connected, a wire groove 3 is provided on the mating surfaces of the lower seat body 1 and the upper seat body 2, and two opposite wire grooves 3 constitute a wire hole. Of course, the wire grooves 3 described in this embodiment can be arranged in sequence in plurality to realize forming a plurality of wire holes with different apertures, so as to optimize the adaptability of the measurement;

[0023] A magnetic attraction component 4 and an indication component 5 are provided on the mating surfaces of the lower seat body 1 and the upper seat body 2. The two magnetic attraction components 4 are magnetically attracted to each other, and the indication component 5 is used to indicate the attraction state.

[0024] In some embodiments, the magnetic attraction assembly 4 in the utility model includes a fixing member 41 and a magnetic member 42, wherein the magnetic member 42 is a permanent magnet, and the fixing member 41 and the magnetic member 42 are detachably connected. Of course, it should be noted that the two permanent magnets on the mating surfaces of the lower seat body 1 and the upper seat body 2 should be designed with opposite magnetic properties to ensure that the lower seat body 1 and the upper seat body 2 can be attracted;

[0025] The mating surfaces of the lower seat body 1 and the upper seat body 2 are both provided with mounting grooves 11 , and the fixing member 41 is installed in the mounting grooves 11 .

[0026] On the basis of the above embodiments, the fixing member 41 in the utility model includes a connecting bottom surface 411 and a plurality of claws 412 circumferentially distributed on the connecting bottom surface 411, and an annular groove 421 is provided on the outer side of the magnetic member 42, and the claw ends of the plurality of claws 412 are clamped in the annular groove 421, that is, in this embodiment, the design of the claws 412 is adopted to realize the fixation of the magnetic member 42. Preferably, the connecting bottom surface 411 and the claws 412 described in this embodiment adopt an integrated structural design, and rubber parts can be used to ensure deformation elasticity.

[0027] Furthermore, in this embodiment, a guide block 413 is fixed to the outer wall of at least one of the claws 412, and a guide groove adapted to the guide block 413 is opened on the inner side of the mounting groove 11. Through the cooperation between at least one guide block 413 and the guide groove, the fixing member 41 can be smoothly moved up and down inside the mounting groove 11 to avoid the fixing member 41 from rotating.

[0028] On the basis of the above embodiments, the fixing member 41 in this embodiment also includes a connecting tube 414 fixed below the connecting bottom surface 411, and the connecting tube 414 is a threaded tube. The lower seat body 1 and the upper seat body 2 are provided with a groove below the mounting groove 11, and a screw 415 is rotatably connected in the groove, and the screw 415 is threadedly connected to the connecting tube 414. That is to say, during the initial installation, the fixing member 41 is inserted into the interior of the mounting groove 11 until the connecting tube 414 contacts the screw 415. Thereafter, the height of the fixing member 41 can be adjusted by rotating the screw 415, and then the height of the magnetic member 42 can be adaptively adjusted to achieve the required height of the magnetic member 42.

[0029] In addition, one end of the screw rod 415 described in the present embodiment passes through the interior of the installation groove 11 and is limited by a retaining spring 416. That is to say, an annular groove is provided on the outer peripheral surface of the screw rod 415 described in the present embodiment, and the retaining spring 416 is clamped in the annular groove to realize the position locking of the screw rod 415. A spring 417 is also provided between the connecting tube 414 and the installation groove 11. The spring 417 is designed to improve the convenience of disassembly of the fixing part 41. That is, when the magnetism of the magnetic part 42 may be weakened or disappear after being hit, the entire fixing part 41 can be driven to move upward by rotating the screw rod 415. After the fixing part 41 moves upward by a predetermined distance, the connecting tube 414 at the bottom is separated from the screw rod 415. Under the resistance of the spring 417, the entire fixing part 41 can drive the magnetic part 42 to pop out from the interior of the installation groove 11, so as to realize the subsequent convenient replacement and maintenance of the magnetic part 42.

[0030] In some embodiments, the indicating component 5 in the utility model includes a protruding block 51 fixed on the lower seat body 1, and an adapting groove 52 opened on the side of the upper seat body 2, the outer sides of the protruding block 51 and the adapting groove 52 are provided with indicating scales 53, and the inner side of the adapting groove 52 is also provided with an avoiding groove 54, and the avoiding groove 54 is a bevel groove, and its design purpose is to avoid the protruding block 51 to avoid the upper seat body 2 from interfering with the protruding block 51 when the upper seat body 2 rotates, that is, when the upper seat body 2 and the lower seat body 1 are attracted, the protruding block 51 and the indicating scale 53 of the adapting groove 52 are relatively in a straight line, so that it is convenient to intuitively observe the current attraction situation.

[0031] In summary, in the utility model, magnetic suction components 4 are installed on the opposite surfaces of the lower seat body 1 and the upper seat body 2. During the test, if the wire pushes the fixture open because the OD is too large, it means that the force is too large, and the wire diameter should be upgraded to the aperture of the next larger OD for measurement until the wire can pass through with resistance but does not push the magnetic component 42 open. In addition, an indicator scale 53 is designed to intuitively observe the attraction between the upper seat body 2 and the lower seat body 1. When the two indicator scales 53 are in a straight line during attraction, it indicates complete attraction. Conversely, when the two indicator scales 53 are misaligned, it may represent that the current wire OD is too large.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
