Description

Technical Field

[0001] This utility model belongs to the field of hydraulic support installation technology, specifically relating to a positioning tool for a hydraulic support structural component limit block. Background Technology

[0002] In coal mining support equipment, hydraulic supports are one of the core components, and the manufacturing and assembly precision of their structural components directly affects the stability and safety of the entire support system. Among them, the limiting block, as a key functional component on the hydraulic support structure (such as the top beam, shield beam, and base), is mainly used to limit the stroke of moving parts, prevent structural interference, and ensure the sequence of actions. The accuracy of its installation position has a significant impact on the overall performance of the support.

[0003] Currently, in the manufacturing and maintenance of hydraulic support structural components, the positioning and installation of limit blocks generally employs traditional methods: manual marking. Operators use measuring tapes, squares, templates, and other tools to manually mark lines on the surface of the structural component according to the dimensions in the drawings to determine the installation position of the limit blocks. This method relies on worker experience and suffers from problems such as large positioning errors, low efficiency, and lack of repeatability, making it particularly difficult to ensure consistency in mass production. Installation deviations of the limit blocks frequently occur, leading to support movement stagnation, structural component interference, and even safety hazards. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art by proposing a positioning fixture for a hydraulic support structural component limit block; it solves the problems of large errors, low efficiency, and poor consistency in manual marking and positioning during the installation of hydraulic support structural components.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] A positioning fixture for a limit block of a hydraulic support structure includes a reference positioning mechanism, an adjustment mechanism, and a limit block positioning mechanism. The reference positioning mechanism includes a reference positioning cylinder with a reference positioning cylinder cover fixedly installed at its end. A reference positioning ear is fixedly installed on the reference positioning cylinder cover. The adjustment mechanism includes a magnet block with an adjustment scale rod fixedly installed on the magnet block. The adjustment scale rod is slidably inserted into the reference positioning ear. After sliding adjustment, the adjustment scale rod is fixedly connected to the reference positioning ear by a locking bolt. The limit block positioning mechanism includes a positioning plate and a positioning plate patch. The positioning plate is rotatably sleeved inside the reference positioning cylinder, and a positioning plate patch is fixedly installed on the positioning plate.

[0007] Furthermore, the reference positioning cylinder is a cylindrical structure with openings at both ends. A reference positioning cylinder cover is fixedly installed at one end of the reference positioning cylinder. The reference positioning cylinder cover is a circular plate structure and is detachably installed on the reference positioning cylinder.

[0008] Furthermore, a reference positioning ear is fixedly provided at the center of the outer side of the reference positioning cylinder cover. A through-hole is provided on the reference positioning ear, and the axis of the through-hole is set along the axis of the reference positioning cylinder.

[0009] Furthermore, a threaded hole with internal and external communication is provided on the side wall of the insertion hole, which is used to screw in a locking bolt.

[0010] Furthermore, the magnet block has a square frame structure, and the adjustment scale rod is fixedly installed at the center of one end face of the magnet block; one end of the adjustment scale rod is fixedly connected to the magnet block, and the axis of the adjustment scale rod is perpendicular to the end face of the magnet block.

[0011] Furthermore, the end of the adjustment scale rod furthest from the magnet is slidably inserted into the insertion hole of the reference positioning ear.

[0012] Furthermore, the adjustment scale rod is a round rod-shaped structure with a row of scale lines arranged along its axial direction on its outer surface.

[0013] Furthermore, the positioning plate includes a circular segment and a square segment, with the square segment fixedly disposed at the outer edge of the circular segment; the circular segment of the positioning plate is rotatably sleeved on the outside of the reference positioning cylinder, and the square segment of the positioning plate is fixedly connected to the positioning plate patch.

[0014] Furthermore, the positioning plate patch has a planar plate structure and a positioning groove is provided on the positioning plate patch.

[0015] The beneficial effects of this utility model compared to the prior art are as follows: (1) The positioning tooling device of the limit block completely eliminates the visual and operational errors caused by manual scribing and measurement through mechanical positioning and rigid structure to transfer dimensions. The positioning accuracy effectively ensures the assembly quality and operational reliability of the hydraulic support.

[0016] (2) The operation of this device is simple: three steps: "fixing the tooling, putting in the parts, and installing". It can be completed quickly by a single person, and is especially suitable for mass production and overhaul operations, which greatly improves work efficiency.

[0017] (3) By designing replaceable positioning cylinders, one set of tooling can be applied to various types of structural parts, with good versatility and flexibility, reducing the number of professional tooling and manufacturing costs. Attached Figure Description

Detailed Implementation

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0020] like Figure 1 As shown in Figure 2, this utility model provides a positioning fixture for a hydraulic support structural component limit block, including a reference positioning mechanism, an adjustment mechanism, and a limit block positioning mechanism. The reference positioning mechanism includes a reference positioning cylinder 1, with a reference positioning cylinder cover 2 fixedly installed at the end of the reference positioning cylinder 1, and a reference positioning ear seat 3 fixedly installed on the reference positioning cylinder cover 2. The adjustment mechanism includes a magnet block 6, with an adjustment scale rod 7 fixedly installed on the magnet block 6. The adjustment scale rod 7 is slidably and adjustablely inserted into the reference positioning ear seat 3. After the adjustment is completed, the adjustment scale rod 7 is fixedly connected to the reference positioning ear seat 3 by a locking bolt 8. The limit block positioning mechanism includes a positioning plate 4 and a positioning plate patch 5. The positioning plate 4 is rotatably sleeved inside the reference positioning cylinder 1, and the positioning plate patch 5 is fixedly installed on the positioning plate 4.

[0021] The reference positioning cylinder 1 is a cylindrical structure open at both ends. A reference positioning cylinder cover 2 is fixedly installed at one end of the reference positioning cylinder 1. The reference positioning cylinder cover 2 is a circular plate-like structure and is detachably installed on the reference positioning cylinder 1. A reference positioning lug 3 is fixedly installed at the center of the outer surface of the reference positioning cylinder cover 2. A through-hole is provided on the reference positioning lug 3, with its axis aligned with the axis of the reference positioning cylinder 1. A threaded hole with internal and external communication is provided on the side wall of the through-hole for threading a locking bolt 8.

[0022] The magnet block 6 has a square frame structure, and the adjustment scale rod 7 is fixedly installed at the center of one end face. One end of the adjustment scale rod 7 is fixedly connected to the magnet block 6, and the axis of the adjustment scale rod 7 is perpendicular to the end face of the magnet block 6. The adjustment scale rod 7 has a round rod structure, and a row of scale lines is arranged on its outer surface along its axis.

[0023] The end of the adjusting scale rod 7 furthest from the magnet 6 is slidably inserted into the insertion hole of the reference positioning ear 3. The distance between the magnet 6 and the reference positioning ear 3 is adjusted by sliding the adjusting scale rod 7 within the insertion hole. The distance to be adjusted is determined by the relative relationship between the scale lines on the reference positioning ear 3 and the adjusting scale rod 7. After adjustment, tighten the locking bolt 8 to fix the adjusting scale rod 7 and the reference positioning ear 3.

[0024] The positioning plate 4 includes a circular segment and a square segment, with the square segment fixedly disposed at the outer edge of the circular segment. The circular segment of the positioning plate 4 is rotatably sleeved on the outside of the reference positioning cylinder 1, and the square segment of the positioning plate 4 is fixedly connected to the positioning plate patch 5.

[0025] The positioning plate patch 5 is a planar plate structure, and a positioning groove is provided on the positioning plate patch 5. The shape of the positioning groove corresponds to the shape of the limiting block.

[0026] like Figure 3 As shown, the working principle of this utility model is as follows: The first step is to insert the reference positioning cylinder 1 into the reference hole of the structural component. The reference positioning cylinder 1 serves as the positioning reference, providing an accurate spatial coordinate origin for the entire tooling.

[0027] The second step is to adjust the required length of the adjusting scale rod 7 by controlling the sliding of the adjusting scale rod 7 inside the reference positioning ear 3 according to the dimensions in the drawing; and to adjust the angle of the adjusting scale rod 7 by controlling the rotation of the reference positioning cylinder 1 inside the reference hole of the structural component; after the length and angle of the adjusting thread rod are adjusted, tighten the locking bolt 8 to fix the adjusting scale rod 7 to the reference positioning ear 3.

[0028] The third step is to attach the magnet 6 to the reference surface of the structural component, thereby fixing the tooling to the structural component.

[0029] The fourth step is to control the rotating plate to rotate outside the reference positioning cylinder 1 so that the positioning plate patch 5 comes into contact with the magnet block 6, thereby positioning the positioning plate patch 5; then the limiting block is placed inside the positioning groove on the positioning plate patch 5 and pushed onto the mounting surface of the structural component, thereby positioning the limiting block.

[0030] The fifth step is to weld or fasten the limit blocks.

[0031] Step 6: Remove the tooling and complete the positioning and installation.

[0032] The core working principle of this invention is as follows: by using a reference positioning mechanism with the characteristics of the structure itself as a reference, the possibility of accumulated errors from multiple measurements at the edge is eliminated, as is the possibility of inaccurate spatial positioning. The installation position on the theoretical drawings is directly "mapped" to the actual position of the structural component through the design dimensions. Operators only need to fix the tooling and place the limiting block into the limiting block positioning mechanism to achieve precise positioning, without any marking work.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
