Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic cylinder left connector processing equipment, specifically a multi-station hydraulic cylinder left connector drilling and milling fixture. Background Technology

[0002] The left connector of the steering cylinder is welded to the outer edge of the steering cylinder. It is an external connecting part and is used to connect the oil inlet and outlet of the steering cylinder assembly. In addition, the machining plays a very important role in positioning and oil passage for subsequent welding and after-sales use.

[0003] Currently, the machining method involves using a flat-jaw vise to clamp the tooling for single-piece machining of the countersunk hole and through hole of the left connector of the steering cylinder. The distance from the top of the arc of the left connector to the connecting pipe hole requires a high degree of precision, posing significant challenges to the consistency of batch machining for automatic welding of the left connector and connecting pipe. This method is inefficient and costly. Traditional cylinder left connector drilling and milling fixtures often employ a single-station design, meaning only one left connector can be clamped and machined at a time, which greatly limits production efficiency. Therefore, we propose a multi-station cylinder left connector drilling and milling fixture. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multi-station hydraulic cylinder left connector drilling and milling fixture includes a mounting base. Several sliders are evenly slidably arranged on the mounting base, and fixed pressure plates are mounted on the sliders. A V-shaped bracket is also provided on the mounting base. A threaded rod is also provided inside the mounting base, passing through and threadedly connected to the sliders. A worm gear is also connected to the threaded rod via a key. A worm is rotatably mounted on the mounting base, meshing with the worm gear. Several cavities are evenly arranged on the mounting base, and a first telescopic rod is arranged in each cavity. A sliding plate is provided at the end of the telescopic arm of the first telescopic rod, and an insertion rod is provided on the sliding plate. An insertion hole for use with the insertion rod is provided on the V-shaped bracket.

[0006] As a further embodiment of this utility model: the V-shaped bracket is further provided with an installation cavity, a second telescopic rod is provided in the installation cavity, a limit rod is provided at the end of the telescopic arm of the second telescopic rod, and a limit groove is provided on the insertion rod to cooperate with the limit rod.

[0007] As a further improvement of this utility model, a handle is provided at the outer end of the worm gear.

[0008] As a further improvement of this utility model: a first spring is sleeved on the outer side of the first telescopic rod, one end of the first spring is connected to the slide plate, and the other end of the first spring is connected to the inner wall of the cavity.

[0017] The following embodiments will be described in detail with reference to the accompanying drawings. In the drawings and description, similar or identical parts are referred to by the same reference numerals. Furthermore, in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of the utility model. Any obvious modifications or alterations made to this utility model do not depart from its spirit and scope.

[0018] Example Please see Figures 1-4 In this embodiment of the utility model, a multi-station hydraulic cylinder left connector drilling and milling fixture includes a mounting base 1. The mounting base 1 is evenly and slidably provided with a plurality of sliders 2. A fixed pressure plate 3 is provided on the sliders 2. The mounting base 1 is also provided with a V-shaped bracket 4. When drilling and milling of the hydraulic cylinder left connector is required, the operator places the hydraulic cylinder left connector between the fixed pressure plate 3 and the V-shaped bracket 4. Then, the sliders 2 drive the fixed pressure plate 3 to move downward, thereby clamping the hydraulic cylinder left connector, thus ensuring the subsequent processing quality of the hydraulic cylinder left connector. At the same time, it can satisfy the clamping and fixing of multiple hydraulic cylinder left connectors, thereby ensuring the efficiency of the device to a certain extent.

[0019] The mounting base 1 is also equipped with a threaded rod 5, which passes through the slider 2 and is threadedly connected to the slider 2. Rotating the threaded rod 5 will drive the fixed pressure plate 3 to move up and down, thereby better clamping and fixing the left connector of the hydraulic cylinder. A worm wheel 6 is also connected to the threaded rod 5 by a key. A worm 7 is also rotatably mounted on the mounting base 1. The worm 7 and the worm wheel 6 mesh with each other. Rotating the worm 7 will drive the threaded rod 5 to rotate through the worm wheel 6, thereby pressing and fixing the left connector of the hydraulic cylinder through the fixed pressure plate 3. In addition, because the worm wheel 6 and the worm 7 have a self-locking function, the pressing and fixing quality of the left connector of the hydraulic cylinder by the fixed pressure plate 3 is guaranteed. A handle 8 is provided at the outer end of the worm 7. Rotating the handle 8 will drive the worm 7 to rotate.

[0020] The mounting base 1 is also evenly provided with several cavities, in which a first telescopic rod 9 is installed. A sliding plate 10 is installed at the end of the telescopic arm of the first telescopic rod 9, and an insertion rod 11 is installed on the sliding plate 10. The V-shaped bracket 4 is provided with an insertion hole that cooperates with the insertion rod 11. Under the action of the insertion rod 11 and the insertion hole, the V-shaped bracket 4 can be installed and fixed, thus ensuring the efficiency of the V-shaped bracket 4 and facilitating its disassembly. A first spring 12 is sleeved on the outside of the first telescopic rod 9. One end of the first spring 12 is connected to the sliding plate 10, and the other end is connected to the inner wall of the cavity. Under the action of the first spring 12, the connection quality between the insertion rod 11 and the insertion hole is ensured. The V-shaped bracket 4 also has an installation cavity inside, in which a second telescopic rod 13 is installed. A limiting rod 14 is provided at the end of the telescopic arm of the second telescopic rod 13. The insertion rod 11 is provided with a limiting groove that works in conjunction with the limiting rod 14. Under the action of the limiting rod 14 and the limiting groove, the connection quality between the insertion rod 11 and the insertion hole is ensured. A second spring 15 is sleeved on the outside of the second telescopic rod 13. One end of the second spring 15 is connected to the limiting rod 14, and the other end of the second spring 15 is connected to the limiting rod 14. Under the action of the second spring 15, the connection quality between the limiting rod 14 and the limiting groove is ensured. A handle 1201 is provided on the slide plate 10, which can be used to move the slide plate 10.

[0021] In actual use, the left connector of the hydraulic cylinder is placed between the V-shaped bracket 4 and the fixed pressure plate 3 on the mounting base 1. Then, the operator rotates the handle 8 to drive the worm 7 to rotate. The worm 7 meshes with the worm wheel 6, thereby driving the threaded rod 5 to rotate. Since the threaded rod 5 is threadedly connected to the slider 2, the rotation of the threaded rod 5 will drive the slider 2 and the fixed pressure plate 3 to move up and down until the fixed pressure plate 3 tightly clamps the left connector of the hydraulic cylinder, ensuring its stability during the drilling and milling process. The self-locking function of the worm wheel 6 and the worm 7 effectively prevents the fixed pressure plate 3 from loosening, ensuring the clamping quality. The V-shaped bracket 4 passes through the first cavity in the mounting base 1. The telescopic rod 9 and the insert rod 11 on the slide plate 10 at its end are fixed. The first spring 12 provides elastic force to ensure that the insert rod 11 is stably inserted into the insertion hole on the V-shaped bracket 4. In addition, the second telescopic rod 13 inside the V-shaped bracket 4 and the limiting rod 14 at its end cooperate with the limiting groove on the insert rod 11 to further enhance the stability of the connection. The second spring 15 provides continuous elastic force to the limiting rod 14 to ensure a tight connection. When it is necessary to disassemble or adjust the V-shaped bracket 4, the slide plate 10 can be pulled by the handle 1201 to separate the insert rod 11 from the insertion hole. At the same time, the limiting rod 14 also comes out of the limiting groove, realizing quick and convenient disassembly.
