Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sliding contact line processing technology, specifically relating to an auxiliary positioning tooling for sliding contact line processing. Background Technology
[0002] Sliding conductor rails, as a key device providing continuous power transmission to mobile equipment (such as cranes, automated production line trolleys, and warehousing and logistics equipment), are widely used in modern industry. Their core structure typically consists of two parts: an outer shell that provides insulation, mechanical support, and current collector guidance; and a copper conductor encapsulated within the shell, responsible for carrying and conducting current. The performance and reliability of the sliding conductor rail, such as conductivity, wear resistance, service life, and the smoothness of current collector operation, largely depend on the accurate positioning, straightness, and precise fit of the internal copper conductor with the outer shell. Therefore, efficiently and accurately inserting the copper conductor into the inner cavity of the outer shell is a crucial fundamental process in the manufacturing of sliding conductor rails.
[0003] In the current processing of sliding contact lines, especially in the process of inserting long copper conductors into the corresponding housing, there are generally problems of low efficiency and difficult operation. Due to the relatively compact space inside the housing, when the insertion is performed manually or semi-manually, it is difficult to quickly and accurately keep the end of the copper conductor concentrically aligned with the entrance end of the housing, which slows down the overall assembly speed. Utility Model Content
[0004] The purpose of this utility model is to provide an auxiliary positioning fixture for sliding contact line processing, so as to solve the problems of low efficiency and difficult operation that are commonly found in the current sliding contact line processing, especially in the process of inserting long copper conductors into the corresponding outer shell.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A sliding conductor rail machining auxiliary positioning fixture includes:
[0007] Two positioners are symmetrically arranged inside the sliding contact line housing;
[0008] The connecting rod is installed between the two positioners;
[0009] The positioner includes two symmetrically arranged guide plates, with the front ends of the two guide plates forming outward-opening V-shaped guide openings.
[0010] Preferably, both ends of the connecting rod are equipped with telescopic rods, and the two telescopic rods are respectively connected to two positioners.
[0011] Preferably, one end of the connecting rod has a threaded groove, one end of the telescopic rod is threadedly connected to the threaded groove, and the other end is rotatably connected to the positioner.
[0012] Preferably, the locator includes:
[0013] A groove is formed on one side of the locator, and the guide plate is connected to the inner wall of the groove via a rotating shaft.
[0014] Preferably, the locator further includes:
[0015] The first roller is mounted on the positioner and contacts the inner wall of the sliding contact line housing.
[0016] Preferably, the locator further includes:
[0017] An adjustment groove is provided on the positioner;
[0018] An adjusting seat is installed in an adjusting groove, and the first roller is installed on the adjusting seat.
[0019] Preferably, a second elastic element is connected to the inner wall of the adjusting groove, and one end of the second elastic element is connected to the adjusting seat.
[0020] Preferably, a second roller is installed at the end of the positioner away from the first roller, and the second roller contacts the inner wall of the sliding contact line housing.
[0021] Preferably, a first elastic element is installed on the inner wall of the groove, and the first elastic element is connected to the rotating shaft on the guide plate.
[0022] Preferably, there are two first elastic elements, which are respectively disposed at the top and bottom of the guide plate.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] This invention significantly expands the initial contact range for copper conductor insertion through the V-shaped guide port at the front end of the locator. Even with slight misalignment at the end of the copper conductor, the V-shaped structure guides it to the center position, eliminating the need for repeated manual adjustments, reducing alignment difficulty, accelerating preparation before insertion, and improving overall assembly speed. The telescopic rods at both ends of the connecting rod are threaded together to achieve length adjustment, allowing for flexible adjustment of the distance between the two locators according to different widths of the sliding contact line housing. This eliminates the need for separately designed tooling for different housing specifications. The first and second rollers on the locator convert sliding friction with the inner wall of the housing into rolling friction, significantly reducing the resistance to tooling movement within the housing and enabling smooth movement of the tooling as the copper conductor is inserted.

Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Example 1: Please refer to Figures 1-6 As shown, an auxiliary positioning fixture for sliding conductor rail processing includes:
[0034] Positioners 200, two in number, are symmetrically arranged inside the sliding contact line housing 100;
[0035] A connecting rod 300 is installed between two positioners 200;
[0036] The positioner 200 includes two symmetrically arranged guide plates 201, with the front ends of the two guide plates 201 forming outwardly opening V-shaped guide openings.
[0037] The V-shaped guide port, through its outward expansion design, increases the initial contact range for copper conductor insertion, solving the problem of difficulty in aligning the end of the copper conductor with the outer casing entrance. When the copper conductor is inserted, even if there is a slight deviation, it can be guided to the center position by the V-shaped port, reducing manual alignment operations and improving insertion efficiency. The symmetrical arrangement of the guide plate 201 ensures that the copper conductor enters along the axial direction, avoiding deflection.
[0038] Both ends of the connecting rod 300 are provided with telescopic rods 301, and the two telescopic rods 301 are respectively connected to the two positioners 200.
[0039] The telescopic structure of the telescopic rod 301 makes the distance between the two positioners 200 adjustable, adapting to the sliding contact line housing 100 of different widths.
[0040] One end of the connecting rod 300 is provided with a threaded groove, one end of the telescopic rod 301 is threadedly connected to the threaded groove, and the other end is rotatably connected to the positioner 200, which improves the versatility of the tooling and eliminates the need to design separate positioning tooling for different specifications of sliding contact lines.
[0041] The length of the telescopic rod 301 can be precisely adjusted by means of a threaded connection, and the telescopic rod 301 is rotatably connected to the positioner 200 to prevent the positioner 200 from shifting as the telescopic rod 301 rotates during adjustment.
[0042] Positioner 200 includes:
[0043] A groove 202 is formed on one side of the positioner 200, and the guide plate 201 is connected to the inner wall of the groove 202 via a rotating shaft.
[0044] The first roller 206 is mounted on the positioner 200 and contacts the inner wall of the sliding contact line housing 100.
[0045] A first elastic element 203 is installed on the inner wall of the groove 202, and the first elastic element 203 is connected to the rotating shaft on the guide plate 201.
[0046] There are two first elastic elements 203, which are respectively set at the top and bottom of the guide plate 201. The first elastic element 203 is a spring-loaded spring or a coil spring, which provides a reset elastic force for the guide plate 201 and maintains the initial opening angle of the V-shaped guide opening. When the copper conductor is inserted and leaves the guide plate 201, the elastic force can make the guide plate 201 automatically reset, ensuring that it can still maintain effective guidance when inserted next time. At the same time, the elastic force can adaptively adjust the clamping force of the guide plate 201 according to the diameter of the copper conductor to avoid excessive compression of the copper conductor.
[0047] A second roller 208 is installed at the end of the positioner 200 away from the first roller 206, and the second roller 208 contacts the inner wall of the sliding contact line housing 100.
[0048] The groove 202 provides installation space for the guide plate 201, and the guide plate 201 can rotate around the axis through the pivot connection; the first roller 206 and the second roller 208 convert the sliding friction between the positioner 200 and the inner wall of the housing into rolling friction, reducing the resistance when the tooling moves in the housing, so that the positioner 200 can slide smoothly to adjust its position.
[0049] Example 2: Please refer to Figure 5 The difference between this embodiment and Embodiment 1 is that the locator 200 further includes:
[0050] An adjustment groove 205 is provided on the positioner 200;
[0051] An adjusting seat 204 is installed in an adjusting groove 205, and the first roller 206 is installed on the adjusting seat 204.
[0052] A second elastic element 207 is connected to the inner wall of the adjusting groove 205, and one end of the second elastic element 207 is connected to the adjusting seat 204.
[0053] The adjusting seat 204, under the elastic action of the second elastic element 207, drives the first roller 206 to always be in contact with the inner wall of the sliding contact line housing 100, which can be adapted to sliding contact line housings 100 of different sizes. The second elastic element 207 can be a spring or a spring block, using the elastic force to compensate for dimensional deviations and enhance the fit stability between the positioner 200 and the housing; at the same time, it plays a buffering role when the tooling moves, reducing the impact of vibration on positioning accuracy.
[0054] The working principle and usage process of this utility model are as follows: Based on the size of the sliding contact line housing 100, by rotating the telescopic rods 301 at both ends of the connecting rod 300, the distance between the two positioners 200 is adjusted by utilizing the threaded engagement between the telescopic rods 301 and the threaded grooves of the connecting rods 300, so that the positioners 200 can adapt to the width of the inner cavity of the housing.
[0055] During adjustment, the telescopic rod 301 is rotatably connected to the positioner 200 to prevent the positioner 200 from shifting with the rotation of the telescopic rod 301, ensuring that the two positioners 200 remain symmetrical. The adjusted fixture is placed into the sliding contact line housing 100. The first roller 206 and the second roller 208 on the positioner 200 contact the inner wall of the housing, reducing insertion resistance through rolling friction and allowing the fixture to smoothly enter the housing. Under the elastic force of the second elastic element 207, the adjusting seat 204 drives the first roller 206 to fit tightly against the inner wall of the housing. Even if there are slight deviations in the housing dimensions, the elastic force compensation ensures stable contact while buffering vibrations during insertion.
[0056] As the copper conductor penetrates into the housing, it first contacts the V-shaped guide port at the front end of the positioner 200. The outward-opening structure of the V-shaped guide port expands the initial contact range, and even if there is a slight offset at the end of the copper conductor, it will be guided to the center position by the guide plate 201.
[0057] As the copper conductor continues to penetrate, it pushes the guide plate 201 to rotate around the pivot within the groove 202, which provides rotational space for the guide plate 201. At this time, the first elastic elements 203 (one at the top and one at the bottom) on the inner wall of the groove 202 are compressed, adaptively adjusting the clamping force of the guide plate 201 on the copper conductor to avoid excessive compression and ensure stable entry of the copper conductor along the axial direction. As the copper conductor continues to penetrate, the fixture moves along the interior of the housing under the push of the copper conductor. The first roller 206 and the second roller 208 convert sliding friction into rolling friction, reducing movement resistance and allowing the fixture to move smoothly and synchronously with the copper conductor.
[0058] The adjusting seat 204 can be flexibly adjusted in the adjusting groove 205. With the buffering effect of the second elastic element 207, the vibration during the movement is reduced and the positioning accuracy is guaranteed. After the copper conductor is completely inserted into the shell, it is separated from the contact with the guide plate 201. The elastic force of the first elastic element 203 drives the guide plate 201 to reset around the rotating shaft, so that the V-shaped guide opening returns to the initial open state, preparing for the next insertion of the copper conductor.
[0059] After the copper conductor is inserted, the fixture is removed from the housing. If other sizes of housings are required, the adjustment process can be repeated to achieve reuse of the fixture.
[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
