Referring to fig. 1, a schematic structure diagram of an automatic wire unwinding device according to the present invention is shown. In this exemplary embodiment, the automatic wire unwinding device according to the present invention is described as being applied to an operation of unwinding the connector 200 of a locomotive consist. Those skilled in the art will readily appreciate that numerous modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the related designs of the present invention to connectors 200 of other types of devices, while remaining within the principles of the automatic wire ejector set forth herein.
As shown in fig. 1, in the present embodiment, the automatic thread-withdrawing device provided by the present invention is used for withdrawing the pins 220 in the connector 200, and the automatic thread-withdrawing device includes a bracket 110, a fixing base 120 and a needle withdrawing box 130. Referring to fig. 2-5 in conjunction, a cross-sectional view taken along line A-A of fig. 1 is representatively illustrated in fig. 2; an enlarged schematic view of needle retraction cassette 130 in a state is representatively illustrated in fig. 3; an enlarged schematic view of the needle retraction cassette 130 in another state is representatively illustrated in fig. 4; an enlarged schematic view of the needle retraction cassette 130 mated with the connector 200 in a state is representatively illustrated in fig. 5;
an enlarged schematic view of the needle retraction cassette 130 mated with the connector 200 in another state is representatively illustrated in fig. 6. The structure, connection mode and functional relation of the main components of the automatic wire unwinding device according to the present invention will be described in detail below with reference to the above drawings.
As shown in fig. 1 to 4, in the present embodiment, the fixing base 120 is disposed at the bottom of the bracket 110, the fixing base 120 can fix the connector 200 to be removed, and the fixing base 120 can be, but not limited to, a bench clamp type working mode. The needle retraction cassette 130 is disposed at the top of the support 110 in a liftable manner by the driving mechanism 140, the needle retraction cassette 130 is disposed above the fixing base 120, and the height of the support 110 can be calculated and determined according to the driving stroke of the driving mechanism 140 and the matching distance between the connector 200 and the insertion hole 211 (step surface 2111). The needle retraction box 130 includes an upper support plate 131, a lower support plate 132, and an elastic member 135. The upper support plate 131 is connected to the driving mechanism 140, and the upper support plate 131 is provided with a plurality of downwardly extending pins 133. The lower support plate 132 is located below the upper support plate 131, and the lower support plate 132 is provided with a plurality of downwardly extending bushings 134, and the top of the bushings 134 is open on the top surface of the lower support plate 132. The plurality of thimble 133 corresponds to the plurality of sleeve 134, and the thimble 133 is partially disposed through the corresponding sleeve 134. Wherein the lumen inner diameter of sleeve 134 is larger than the aperture of insertion hole 211 of connector 200 through which pin 220 is inserted. The elastic member 135 is connected between the upper support plate 131 and the lower support plate 132, and can play a role in adjusting and buffering the pressure of the ejector pins 133, and automatically retract the ejector pins 133 after needle withdrawal.
Accordingly, when the automatic thread-withdrawing device according to the present invention is used for withdrawing threads from the connector 200, as shown in fig. 5, the needle withdrawing box 130 is approximately in the state shown in fig. 3, the needle withdrawing box 130 is respectively inserted into the accommodating cavities 210 of the connector 200 for accommodating the pins 220 by the plurality of sleeves 134, and the pins 220 of the connector 200 are partially inserted into the cavities of the sleeves 134. Because the inside diameter of the lumen of sleeve 134 is larger than the bore diameter of receptacle 211 of connector 200, sleeve 134 cannot be inserted into receptacle 211 against bottom step surface 2111 of receiving cavity 210. At this time, the driving mechanism 140 continues to drive the needle retraction cassette 130 to descend, that is, specifically, pushes the upper support plate 131 downward, so that the upper support plate 131 compresses the elastic member 135 to move downward near the lower support plate 132, and the relative position of the lower support plate 132 and the connector 200 is not changed in the process. The ejector pins 133 move downward with the upper support plate 131 until the lower ends of the ejector pins 133 contact the upper ends of the pins 220, and eject the pins 220 out of the connector 200 through the insertion holes 211, thereby completing the operation of withdrawing the pins 220 from the connector 200. After the thread withdrawing is completed, the driving mechanism 140 is retracted, the elastic member 135 releases elastic potential energy to reset the upper support plate 131 relative to the lower support plate 132, and the driving mechanism 140 continues to retract to integrally withdraw the needle withdrawing box 130 until the sleeve 134 is moved upwards out of the accommodating cavity 210.
Through the design, the invention can simultaneously realize the automatic withdrawing operation of a plurality of pins 220 of the connector 200. Accordingly, unlike the existing wire stripper which can only withdraw one pinhole at a time, the wire stripper has the advantages of short time and less occupied force when completely stripping the connector 200 during repairing the screen cabinet, greatly reduced artificial uncertain factors during the wire stripping operation and difficult damage due to the driving design of the driving mechanism 140, thereby realizing portable and automatic wire stripping, improving the repairing efficiency of the screen cabinet of the locomotive, and saving time, releasing manpower, batch wire stripping, protecting tools and cost.
Alternatively, in this embodiment, the outer diameter of the thimble 133 may be equal to the inner diameter of the sleeve 134, so that the thimble 133 can be guided by the sleeve 134 to move up and down in the sleeve 134, thereby preventing the thimble 133 from shaking in the sleeve 134. In some embodiments, the outer diameter of the thimble 133 may be slightly smaller than the inner diameter of the passage, but not limited thereto.
Alternatively, as shown in fig. 3-6, in this embodiment, the needle retraction cassette 130 may also include a support post 136. Specifically, one end of the support column 136 is connected to the upper support plate 131, and the lower support plate 132 is slidably sleeved on the other end of the support column 136. On this basis, the elastic member 135 may be a spring wound around the supporting column 136, and the spring is located between the upper support plate 131 and the lower support plate 132. Through the design, the invention can further strengthen the connection strength between the upper support plate 131 and the lower support plate 132 by utilizing the design of the support column 136, thereby optimizing the overall structural strength of the needle retraction box 130. Furthermore, the present invention can provide a guiding function and an arrangement position for the elastic member 135 using the supporting columns 136. In some embodiments, to achieve the elastically resettable connection between the upper bracket 110 and the lower bracket 110, other types of elastic members 135 and connection mechanisms, such as gas springs, spring sleeves, etc., may be connected between the upper bracket 110 and the lower bracket 110, but not limited thereto.
Further, as shown in fig. 3 to 6, based on the design that the needle retraction cassette 130 includes the support post 136, in the present embodiment, the upper end of the support post 136 may be provided with threads. Accordingly, the upper end of the support column 136 may be fixed with the upper support plate 131 by the fastening nut 137. Through the design, the connection between the support column 136 and the upper support plate 131 is realized in a threaded connection mode, so that the assembly and disassembly are convenient, and the operation is simple. Furthermore, the present invention can adjust the relative fixing positions of the support column 136 and the upper support plate 131 by adjusting the fastening nut 137, so as to provide different extending strokes of the ejector pins 133, thereby meeting the wire withdrawing requirements of different types of connectors 200.
Further, as shown in fig. 3 to 6, based on the design that the needle retraction cassette 130 includes the support post 136, the lower end of the support post 136 may be provided with threads in the present embodiment. Accordingly, the lower end of the support post 136 may be threaded with a stop nut 138, the stop nut 138 being located below the lower support plate 132. With the design, the limiting nut 138 can be adopted to limit the lower support plate 132. Furthermore, the invention can realize the adjustment of the relative positions of the lower support plate 132 and the upper support plate 131 by adjusting the limit nuts 138 so as to meet the wire withdrawing requirements of different types of connectors 200.
Alternatively, as shown in fig. 5 and 6, in the present embodiment, the thimble 133 may include a first connecting portion 1331 and a needle portion 1332. Specifically, the top of the first connection part 1331 is provided with a screw hole such that the first connection part 1331 can be inserted into the through hole of the upper bracket 131 and fixed to the upper bracket 110 by a fastening screw 1333 screw-engaged with the screw hole. The needle portion 1332 is connected to the lower end of the first connecting portion 1331 and extends downward, and the needle portion 1332 can be inserted into the sleeve 134. On this basis, the outer diameter of the needle portion 1332 may be smaller than the outer diameter of the first connection portion 1331, so that the first connection portion 1331 having a larger outer diameter is convenient to provide the screw holes, thereby improving the connection strength between the thimble 133 and the upper support plate 131.
Alternatively, as shown in fig. 5 and 6, in the present embodiment, the sleeve 134 may include a second connection portion 1341 and a shaft portion 1342, and the lumen of the sleeve 134 penetrates the second connection portion 1341 and the shaft portion 1342. Specifically, the outer circumference of the second connection part 1341 is provided with external threads so that the sleeve 134 can be screw-fixed to a screw hole provided in the lower bracket 110 through the second connection part 1341. The pipe body portion 1342 is connected to the lower end of the second connection portion 1341 and extends downward, and the pipe body portion 1342 can be inserted into the receiving chamber 210 of the connector 200. On this basis, the outer diameter of the pipe body portion 1342 may be smaller than the outer diameter of the second connection portion 1341, so that the second connection portion 1341 having a larger outer diameter facilitates the provision of the external screw thread, thereby improving the connection strength of the sleeve 134 and the lower support plate 132.
In addition, based on the specific design of the needle retraction box 130, the present invention can selectively connect the required number and arrangement of the ejector pins 133 in the plurality of through holes of the upper support plate 131, and select the corresponding screw holes in the plurality of screw holes of the lower support plate 132, and connect the corresponding bushings 134 in the number and arrangement of the bushings for different types of connectors 200. Accordingly, the present invention can realize the adaptation to different types of connectors 200 through the detachable designs of the thimble 133 and the sleeve 134, and further expand the application range of the present invention.
Specifically, as shown in fig. 1 and 2, in the present embodiment, the bracket 110 may include a top beam 111, a top beam 112, and two columns 113. Specifically, the top beam 111 and the top beam 112 are arranged at intervals, the top beam 111 is used for connecting the driving mechanism 140, and the top beam 112 is used for setting the fixing seat 120. Two upright posts 113 are respectively arranged between the two ends of the top beam 112 and the two ends of the top beam 112. Accordingly, the bracket 110 has a frame structure, so that the integrity of the invention can be improved, and the equipment can be conveniently transferred and transported. In some embodiments, the bracket 110 may also have other shapes, such as a door frame, etc., but not limited thereto.
Alternatively, in the present embodiment, the fixing base 120 may include a base body and at least one pair of screw fixtures. Specifically, the housing may be disposed at the bottom of the bracket 110, such as on the top beam 112 of the bracket 110. Two screw fixtures of the same pair may be disposed at both sides of the housing at intervals in a horizontal direction, thereby enabling the connector 200 to be adjustably positioned on the housing and to be kept horizontal. Through the design, the fixing seat 120 can keep horizontal positioning on the connector 200, stability and accuracy of a wire withdrawing process are guaranteed, and damage to the wire withdrawing box connector 200 caused by uneven stress is avoided.
Alternatively, in the present embodiment, the driving mechanism 140 may employ an electric push rod. Specifically, the cylinder of the electric putter may be connected to the top of the bracket 110, for example to the top beam 111. The telescopic rod of the electric push rod extends out from the bottom of the cylinder, and the needle withdrawing box 130 can be connected to the lower end of the telescopic rod. In some embodiments, other devices may be used as the driving mechanism 140 to drive the needle retraction cassette 130 to move up and down, such as a linear motor, a hydraulic cylinder, etc., but not limited thereto.
Alternatively, in this embodiment, taking the specification of the connector 200 typically used in locomotive cabinets as an example, the maximum travel of the drive mechanism 140 may be 80mm to 120mm, such as 80m, 90mm, 100mm, 120mm, etc. In some embodiments, the maximum stroke of the driving mechanism 140 may be less than 80mm, or may be greater than 120mm, such as 75mm, 130mm, etc., and may be flexibly selected according to different specifications of the connector 200, which is not limited thereto.

In some embodiments, the automatic wire unwinding device of the present invention may also employ other voltage levels or maximum operating range of the driving mechanism 140. For example, a propeller shaft with a maximum working range of 40mm or more and a maximum thrust of 150N or more may be used instead. It should be noted that, the wire withdrawing box and driving mechanism 140 in this embodiment is designed by using the 50-core connector 200 commonly used in locomotive screen cabinets as a main application object, and other types of connectors 200 just need to calculate the distribution size of the insertion holes 211, adjust the distances between the holes (through holes and screw holes) of the upper support plate 131 and the lower support plate 132, measure the aperture of the connector 200, and manufacture the sleeve 134 with proper diameters, so that the whole wire withdrawing of the connector 200 with other specifications can be realized, and the proper needle withdrawing box 130 can be manufactured.
