Description

Technical Field

[0001] This utility model belongs to the field of clamping technology, specifically relating to a manual switching mechanism. Background Technology

[0002] In the field of intelligent manufacturing, tooling fixtures and jigs, as core equipment in the production process, directly affect the overall commissioning progress of tooling equipment and its adaptability to various shapes and objects through their design, installation, and debugging. They are key factors in determining production costs and efficiency. As the final executor of industrial production, the effective realization of tooling fixture functions is crucial for accelerating the production process and improving adaptability.

[0003] In existing technologies, industrial fixtures mostly use fixed single parts for support and clamping. When clamping a workpiece, if the support or clamping block does not fit properly, the screws and locating pins of the fixed part need to be removed, and the support or clamping can be achieved manually by adjusting the shims. This method is not only time-consuming and labor-intensive, but also inefficient and cannot be adapted to objects of other shapes. Furthermore, it may cause many problems due to improper adjustment. Therefore, there is an urgent need for a new type of positioning block to solve the above technical problems. Utility Model Content

[0006] Preferably, the graduation rings on the fixed connecting seat are spaced 0.5 mm apart.

[0007] Preferably, the surface of the adjusting nut is provided with anti-slip knurling.

[0008] Preferably, the fixed connecting seat is provided in the mounting groove, and the braking spring and the scale indicator baffle are located in the mounting groove.

[0009] Preferably, the combined structure of the fixed connecting seat, support block, adjusting nut, and scale indicator baffle has dimensions of 65mm in length, 56mm in width, and 22mm in thickness.

[0015] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0016] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] like Figure 1-3 As shown, a manual switching mechanism includes a fixed connecting seat 1, a support block 2, an adjusting nut 3, a damping spring 4, and a scale indicator stop 5. The fixed connecting seat 1 serves as the basic component, with a columnar structure as its main body. A scale ring 6 is arranged around the side, with a scale interval of 0.5mm. The bottom is fixedly connected to an external tooling fixture or equipment through bolt holes. The front end of the support block 2 is designed as a contact surface with the workpiece, and the rear end is machined with external threads so that it can be screwed into the internal thread hole of the adjusting nut 3. The outer wall of the adjusting nut 3 is provided with anti-slip knurling for easy manual rotation, and its front end has a stepped structure to ensure that it forms a limiting fit with the inner hole of the fixed connecting seat 1 after being screwed into the support block 2. The damping spring 4 is sleeved on the tail of the support block, and the scale indicator stop 5 is locked to the tail of the support block 2 by screws 7. The scale indicator stop 5 has a protrusion 8 for indicating the scale ring on the fixed connecting seat 1. During assembly, first screw the support block 2 and adjusting nut 3 together, and then insert the whole assembly into the axial through hole of the fixed connecting seat 1. Next, install the braking spring 4 and the scale indicator stop plate 5 sequentially at the tail of the fixed connecting seat 1, and lock the scale indicator stop plate 5 to the tail end face of the fixed connecting seat 1 with screws. The front end protrusion of the scale indicator stop plate 5 is pointer-shaped, corresponding to the scale ring of the fixed connecting seat 1, and the rear end abuts against the braking spring 4 to form an anti-loosening structure. The combined dimensions of the entire mechanism are 65mm in length, 56mm in width, and 22mm in thickness, making it suitable for installation in confined spaces.

[0019] When the mechanism is installed on the clamping or supporting side of the tooling fixture, the height of the supporting or clamping surface is adjusted by manually rotating the adjusting nut 3, which moves the supporting block 2 along the axial direction of the fixed connecting seat 1. When rotating the adjusting nut 3, the anti-slip knurling provides friction, allowing operation without tools. The protruding pointer of the scale indicator 5 moves on the scale ring as the adjusting nut 3 rotates, displaying the adjustment value in real time; for example, each rotation corresponds to a scale change of 0.5mm, ensuring adjustment accuracy. When the contact surface of the supporting block 2 is in close contact with the workpiece surface, adjustment stops. The stop spring 4 exerts axial pressure on the adjusting nut 3 through the scale indicator 5, preventing the mechanism from loosening during operation. If the workpiece shape is changed, the extension length of the supporting block 2 can be readjusted by directly rotating the adjusting nut 3. If the workpiece shape differs significantly, the entire mechanism can be disassembled and replaced, or only the screws need to be removed to remove the supporting block 2 for replacement, without disassembling other fixed parts, significantly shortening the debugging time. The values ​​recorded by the scale ring can be directly applied to the rapid adjustment of similar workpieces, realizing "one-time debugging and repeated use", which significantly improves the adaptability and cost economy of tooling fixtures.

[0020] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
