Description

Technical Field

[0001] This utility model relates to the field of lathe auxiliary equipment technology, specifically a hydraulic center support mounting structure. Background Technology

[0002] The hydraulic center support mounting structure is a piece of equipment used in the lathe machining industry, mainly for the rapid installation and commissioning of the hydraulic center support.

[0003] In lathe parts machining, the hydraulic center rest is a key tooling for achieving high-precision support. The current mainstream installation method has significant drawbacks: the existing hydraulic center rest is fixed by screws, which is time-consuming; after installation, the adjustment is done by shims and screws, which needs to be repeated several times. Furthermore, if the screws are not tightened diagonally or the stress changes before and after tightening, the accuracy will be lost, which depends on the operator's experience. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic center frame installation structure, which solves the problems of long installation time and inconvenient subsequent debugging of hydraulic center frames.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic center frame mounting structure, comprising a hydraulic center frame fixedly mounted on a mounting bracket, the mounting bracket having two fine-tuning mechanisms for easy fine-tuning after installation, a mounting base below the mounting bracket, a cam handle (NBK LZXS-GV) fixedly mounted on one side of the mounting base, and a handle fixedly mounted on the other side of the mounting base, a guide post fixedly mounted at the lower end of the handle, the guide post being slidably mounted in a hole in the mounting base and slidably mounted through a central hole in a base connecting block, the guide post having an eccentric circular design, the other end of the guide post being slidably mounted inside the mounting base, the circular groove opening at the end of the guide post being fixed in position by a set screw, a clamping screw being threadedly connected to the lower end of the base connecting block, the clamping screw being fixedly mounted at the center of the lower part of the base, thereby allowing the handle to quickly tighten the base by converting rotational movement into vertical movement within a small range.

[0006] Preferably, a vertical plate is fixedly installed on the upper surface of the mounting bracket, and a reinforcing rib is fixedly installed between the mounting bracket (2) and the vertical plate, thereby strengthening the overall rigidity of the mounting bracket.

[0007] Preferably, one side of the mounting bracket is provided with a stepped protrusion corresponding to the cam handle, so that the mounting bracket can be rigidly mounted on the mounting base.

[0008] Preferably, one of the fine-tuning mechanisms is located on the side of the mounting bracket on the hydraulic center frame, and the other is located on the lower part of the mounting bracket on the hydraulic center frame, thereby enabling rapid fine-tuning of the installation angle of the hydraulic center frame.

[0009] Preferably, the lower surface of the mounting bracket is provided with a wedge-shaped protrusion corresponding to the wedge-shaped groove of the mounting base, so that the mounting bracket and the mounting base can be quickly positioned and installed.

[0010] Preferably, the surface of the hydraulic center frame is provided with screw holes that mate with the screw clearance, thereby allowing the hydraulic center frame to have a certain adjustable range.

[0011] Preferably, the guide post is provided with cylinders of different centers and diameters at the center of the base connecting block, and a slotted notch is opened at the end of the cylinder. Thus, under the premise of fixing the guide post, the rotation of the handle can drive the eccentric guide post in the middle to rise, changing the rotational movement to a vertical movement. The guide post drives the base to rise, clamping the base and the mounting base on the lathe guide rail.

[0012] This utility model provides a hydraulic center frame mounting structure. It has the following advantages:

[0013] This hydraulic center frame mounting structure enables quick replacement and disassembly of the base and mounting base, as well as the mounting base and mounting bracket, through the eccentric wheel guide column and cam handle, thereby reducing installation time.

[0014] This hydraulic center frame mounting structure allows for rapid adjustment of the concentricity of the hydraulic center frame through fine-tuning, while ensuring accuracy. Attached Figure Description

[0023] 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. Example

[0024] Please see Figure 1-7 This utility model embodiment provides a hydraulic center frame mounting structure, including a hydraulic center frame 4, which is fixedly mounted on a mounting bracket 2. Two fine adjustment mechanisms 3 are fixedly mounted on one side of the mounting bracket 2, respectively on the side and bottom of the hydraulic center frame 4. A mounting base 1 is provided below the mounting bracket 2. A cam handle 5 is fixedly mounted on one side of the mounting base 1, and a handle 7 is fixedly mounted on the other side of the mounting base 1. A guide post 10 is fixedly mounted at the lower end of the handle 7. The guide post 10 is slidably mounted through a hole in the mounting base 1 and through a center hole in a base connecting block 8. The other end of the guide post 10 is slidably mounted inside the mounting base 1. A set screw 11 is threadedly connected to the lower surface of the mounting base 1. A clamping screw 9 is threadedly connected to the lower end of the base connecting block 8 and is fixedly mounted at the center of the lower part of the base 10.

[0025] It should be noted that, in this embodiment, as Figure 1-3As shown, when installing the hydraulic center frame 4, first place the base 6 parallel to the lathe guide rail. After aligning the mounting base 1 slot with the lathe guide rail, rotate the base 6 90° to be perpendicular to the lathe guide rail. A guide post 10 is fixedly installed at the lower end of the handle 7. The guide post 10 is a cylinder with a different diameter at the base connecting block 8, forming an eccentric design. When the set screw 11 fixes the guide post 10, rotating the handle 7 causes the eccentric cylinder in the middle of the guide post 10 to rotate. The eccentric cylinder moves around the center of the front guide post, and its outer edge pushes the inner edge of the center hole of the base connecting block 8, turning the force in the direction of rotation of the handle 7 into the force on the base connecting block 8. The downward force causes the base connecting block 8 to rise, clamping the base 6 and mounting base 1 onto the lathe guide rail. Then, the mounting bracket 2 is pushed perpendicularly into the wedge-shaped groove on the upper surface of the mounting base 1. After the wedge-shaped protrusion and the wedge-shaped groove are fully engaged, the cam handle 5 is rotated to lock the stepped protrusion at the corresponding position of the mounting bracket 2 until the cam handle 5 can no longer be turned and is fully locked. Then, the hydraulic center frame 4 is fixed to the vertical plate 22 by screws that are not fully tightened. The angle of the hydraulic center frame 4 is adjusted by the fine-tuning mechanism 3. After the concentricity adjustment of the hydraulic center frame 4 and the workpiece is completed, the screws are tightened diagonally in sequence to complete the installation.
