Description

Technical Field

[0001] This utility model belongs to the field of composite material production technology, and specifically relates to a guide structure. Background Technology

[0002] Insulating core rods are key components of high-voltage power grid support insulators. Due to their light weight, corrosion resistance, and excellent insulation performance, they have been widely used. However, in the actual production process of insulating core rods, hydraulic traction equipment is used to pull the insulating core rods out of the mold. In order to ensure that the insulating core rods can be pulled out stably and evenly, it is usually necessary to straighten the direction of movement of the insulating core rods.

[0003] Currently, manufacturers mainly rely on adjusting the tension of the yarn frame and the position of the mold to adjust the straightness of the insulating core rod. However, due to the differences in the technical level of operators and the complexity of the adjustment process, the existing adjustment methods have problems such as high operation difficulty and low straightening accuracy, which can easily lead to inconsistent product quality and low pass rate. Utility Model Content

[0004] The purpose of this invention is to provide a guide structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide structure, including a worktable, on which a guide assembly is mounted, the guide assembly including an adjustment fixing frame and a guide body; A stop post is fixedly connected to the lower part of the guide body. An adjusting stud is threadedly connected to the guide body. One end of the adjusting stud passes through the stop post. A stop block is fixedly connected to the end of the adjusting stud that protrudes from the stop post. A bearing is nested inside the guide body. A rubber post is nested outside the bearing.

[0006] In a preferred embodiment, the adjusting and fixing frame has a guide cavity, and the bottom of the guide body and the abutment post cooperate to form a clamping structure, which is slidably installed on the side wall of the guide cavity.

[0007] In a preferred embodiment, the guide assembly further includes a positioning scale, which is mounted on one side of the adjustment bracket.

[0008] In a preferred embodiment, a positioning groove is provided on the worktable, a fixing pin is disposed in the positioning groove, and plug blocks are fixedly connected to both sides below the adjusting fixing frame, the plug blocks engaging and fixing in the positioning groove with the fixing pin.

[0009] In a preferred embodiment, a support plate is laid on the workbench.

[0010] In a preferred embodiment, a padding plate is placed between the support plate and the adjusting and fixing frame.

[0011] In a preferred embodiment, the adjusting and fixing frame is equipped with multiple sets of guide bodies, and an insulating core rod is guided between every two sets of guide bodies.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This guide structure features an adjusting and fixing frame that slides into a clamping structure formed by the guide cavity, the bottom of the guide body, and the abutment post. Combined with the threaded adjusting stud and end abutment block on the guide body, the position of the guide body can be adjusted. Simultaneously, the adjusting and fixing frame achieves stable fixation through the engagement of the plug-in block, positioning groove, and fixing pin. With the assistance of a positioning scale, precise adjustment of the straightness of the insulating core rod can be achieved, significantly improving the quality and pass rate of subsequent products. Furthermore, this straightening method is simple in structure, intuitive in operation, and easy to master, reducing the technical skill requirements for operators and thus improving production efficiency. The guide structure, with its nested structure of bearings and rubber pillars inside the guide body, can provide protection for the insulating core rod that passes through. The bearings can convert the sliding friction during the adjustment of the insulating core rod into rolling friction, thereby preventing scratches on the surface of the insulating core rod caused by hard friction.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figures 1-6 This utility model provides a guide structure, including a workbench 1, on which a guide assembly is installed. The guide assembly includes an adjustment fixing frame 2 and a guide body 3. The adjustment fixing frame 2 is used to support and fix the adjustable guide body 3. An abutment post 31 is fixedly connected to the bottom of the guide body 3. An adjustment stud 33 is threadedly connected to the guide body 3. The bottom end of the adjustment stud 33 passes through the abutment post 31. An abutment block 32 is fixedly connected to the end of the adjustment stud 33 that protrudes from the abutment post 31. A bearing 34 is nested inside the guide body 3. A rubber post 35 is nested outside the bearing 34. Multiple sets of guide bodies 3 are arranged on the adjustment fixing frame 2. An insulating core rod 4 is guided between every two sets of guide bodies 3.

[0018] In this embodiment, the bearing 34 nested inside the guide body 3 can convert the sliding friction of the insulating core rod 4 into rolling friction during straightening and movement, reducing core rod wear. The rubber column 35 nested outside the bearing 34 can dampen the impact and vibration of the insulating core rod 4, further preventing damage to the insulating core rod 4 due to rigid constraints. At the same time, the abutment column 31 below the guide body 3 cooperates with the threaded adjusting stud 33 and abutment block 32 to accurately adjust and fix the position of the guide body 3. Combined with the coordinated guidance of multiple sets of guide bodies 3, it can accurately ensure that each insulating core rod 4 can move in a straight line.

[0019] Please see Figures 2-4 The adjusting and fixing frame 2 has a guide cavity 21. The bottom of the guide body 3 and the abutment post 31 cooperate to form a clamping structure. The clamping structure is slidably installed on the side wall of the guide cavity 21.

[0020] In this embodiment, the clamping structure formed by the bottom of the guide body 3 and the abutment post 31 forms a sliding fit with the side wall of the guide cavity 21, which can effectively limit the lateral displacement and shaking of the guide body 3 during the sliding process, ensuring the straightness of the adjustment direction. At the same time, when the adjustment stud 33 is rotated, it causes the abutment block 32 to rotate and move downward inside the guide cavity 21 until the bottom of the abutment block 32 and the bottom of the inner cavity of the guide cavity 21 are in close contact, so that the friction between the two can be used to fix the adjusted position of the guide body 3. In the above scheme, it should be noted that: since the guide body 3 and the abutment post 31 are fixedly connected, the bottom of the guide body 3 is in contact with the top of the guide cavity 21, and the abutment post 31 is located inside the guide cavity 21, and the top of the abutment post 31 is in contact with the top of the inner cavity of the guide cavity 21, so that the guide body 3 and the abutment post 31 can be clamped and slid on the guide cavity 21. Meanwhile, the material of the abutment block 32 can be rubber, and the friction between the abutment block 32 and the guide cavity 21 is much greater than the rolling friction between the insulating core rod 4 and the rubber column 35. That is, when the external hydraulic traction equipment pulls the insulating core rod 4 to move in a straight line, the abutment block 32 and the guide cavity 21 will not slide due to the force, thus ensuring the stability of the guide body 3.

[0021] Please see Figures 1-5 The guide assembly also includes a positioning scale 5, which is installed on one side of the adjustment and fixing frame 2. A support plate 14 is laid on the workbench 1, and a padding plate 13 is placed between the support plate 14 and the adjustment and fixing frame 2. The positioning scale 5 is placed on the padding plate 13, and the positioning scale 5 is flush with the bottom of the guide body 3.

[0022] In this embodiment, the positioning scale 5 is installed on one side of the adjustment and fixing frame 2 and placed on the padding plate 13, and is flush with the bottom of the guide body 3. This forms a scale reference that directly corresponds to the movement trajectory of the guide body 3. The operator can intuitively read the movement distance of the guide body 3 by observing the correspondence between the bottom of the guide body 3 and the scale of the positioning scale 5. This avoids the problem of errors that are easily caused by the traditional estimation based on experience, and improves the positional consistency when multiple guide bodies 3 work together.

[0023] Please see Figure 2 and Figure 3 The workbench 1 is provided with a positioning groove 11, and a fixing pin 12 is provided in the positioning groove 11. The lower sides of the adjusting fixing frame 2 are fixedly connected with plug blocks 22, and the plug blocks 22 are engaged and fixed in the positioning groove 11 with the fixing pin 12.

[0024] In this embodiment, the workbench 1 is connected to the plug block 22 below the adjustment bracket 2 via the positioning groove 11 and the fixing pin 12, forming a detachable connection. When it is necessary to clean the dust in the guide cavity 21, simply pull out the fixing pin 12 to release the locking constraint between the plug block 22 and the positioning groove 11, and quickly remove the adjustment bracket 2 from the workbench 1 for easy cleaning. After cleaning, the adjustment bracket 2 can avoid the influence of impurities on the sliding fit accuracy of the guide component, ensuring the stability and accuracy of the adjustment action of the guide body 3.

[0025] Working principle and usage process of this utility model: First, place the support plate 14 on the workbench 1. Place the shim plate 13 of appropriate thickness on the workbench 1 according to the height of the guide body 3. Place the positioning ruler 5 on the shim plate 13 and ensure that it is flush with the bottom of the guide body 3. Then, insert the plug block 22 below the adjustment fixing frame 2 into the positioning groove 11 of the workbench 1. Insert the fixing pin 12 to complete the engagement and fix the adjustment fixing frame 2 to the workbench 1. Next, the insulating core rod 4 is placed between the two sets of guide bodies 3, so that the core rod passes through the nested structure composed of bearing 34 and rubber column 35 inside the guide body 3. First, the adjusting stud 33 on the guide body 3 is rotated in the opposite direction, so that it drives the abutment block 32 to rotate and move upward, causing the abutment block 32 and the guide cavity 21 to separate. Then, the guide body 3 is pushed so that the clamping structure formed by the abutment column 31 and the guide body 3 slides on the guide cavity 21, thereby facilitating the adjustment of the position of the guide body 3 and causing the rubber column 35 and the side of the insulating core rod 4 to fit together. Next, the adjusting stud 33 is rotated forward, causing the abutment block 32 to rotate and move downward until the bottom of the abutment block 32 and the bottom of the inner cavity of the guide cavity 21 are in close contact. This allows the friction between the two to fix the adjusted position of the guide body 3. Then, an external hydraulic traction device (this is an existing technical means) is used to pull the insulating core rod 4 to move linearly, causing rolling friction between the insulating core rod 4 and the rubber column 35, which facilitates precise straightening of the movement direction of the insulating core rod 4. Finally, during the adjustment of the position of the guide body 3, the scale of the positioning ruler 5 can be used as a reference to observe the corresponding scale on the bottom of the guide body 3, so that the position of the guide body 3 can be accurately adjusted. When the guide cavity 21 needs to be cleaned, the fixing pin 12 is pulled out, the adjusting fixing bracket 2 is taken out, the dust and impurities in the cavity are cleaned, and the plug block 22 is reinserted into the positioning groove 11 and fixed.
