Description

Technical Field

[0001] This utility model belongs to the field of machining technology, and in particular relates to a clamping device for machining diameter gauges. Background Technology

[0002] A laser diameter gauge is a device used to measure the diameter of various objects. It is widely used in various industries such as wires and cables, enameled wires, metal wires, PVC pipes, and medical devices. It can perform both online and offline testing and can achieve automatic feedback control and online communication with a computer.

[0003] When machining the housing of a diameter gauge, a clamping fixture is often required to hold the housing so that the machine tool can perform grinding. However, the housing often needs to be machined on two sides. The clamping fixture needs to be released after one side is machined and then clamped again after the housing is flipped over, resulting in low machining efficiency. Furthermore, after the housing is fixed, it is necessary to make fine adjustments to the clamped housing to meet the machining requirements, making the housing clamping process time-consuming and labor-intensive. Utility Model Content

Detailed Implementation

[0023] like Figures 1 to 5 As shown, this utility model presents a clamping device for machining a diameter gauge, comprising a base 1, a connecting column 2, and a fixed bracket 3. The connecting column 2 is mounted on the base 1, and the fixed bracket 3 is mounted on the connecting column 2. The connecting column 2 has a rotating shaft 4, and the fixed bracket 3 has a sleeve 5, which is fitted onto the rotating shaft 4 and rotatably connected to it. The fixed bracket 3 has a clamping mechanism 6 to clamp the diameter gauge housing. There are two sets of both the connecting column 2 and the fixed bracket 3, located on both sides of the base 1, for clamping the diameter gauge housing. This configuration allows the diameter gauge housing to be fixed to the fixed bracket 3. The rotational connection between the fixed bracket 3 and the rotating shaft 4 enables the fixed bracket 3 to be flipped, thereby flipping the diameter gauge housing, facilitating machining and improving machining efficiency. When the diameter gauge housing is fixed, only a minor adjustment to the position of the housing on the fixed bracket 3 is needed. The flipped housing can then be directly machined, avoiding the need for minor adjustments each time traditional clamping fixtures are used.

[0024] As one implementation, the clamping mechanism 6 includes a clamping block 7, a clamping screw 8, and a clamping nut 9. The clamping nut 9 is fixedly connected to the fixed bracket 3, the clamping screw 8 is threadedly connected to the clamping nut 9, and the clamping block 7 is rotatably connected to the clamping screw 8. This configuration facilitates easy clamping of the outer casing and provides a good clamping effect.

[0025] As one implementation, the connecting column 2 is equipped with a sliding rod 10, and the base 1 is equipped with a sliding groove 11. The sliding rod 10 is located in the sliding groove 11 and slidably connected to the sliding groove 11. This configuration allows for easy adjustment of the height of the connecting column 2 on the base 1, enabling it to press down on the outer shell during processing, ensuring a good fixing effect and facilitating shell processing. When flipping is required, the connecting column 2 is moved upwards, allowing the fixing bracket 3 sufficient space to rotate, thus achieving the flipping. The connecting column 2 adopts a concealed design, so that most of its main body is below the base 1 after the outer shell is fixed, thus not affecting the movement of the cutting tool and processing, ensuring the processing effect of the outer shell.

[0026] Specifically, the connecting column 2 has fixing plates 12 at both its upper and lower ends, and a fixing screw 13 is provided between the two fixing plates 12. The fixing screw 13 is rotatably connected to the fixing plates 12. The base 1 has a fixing nut 14, which is threadedly connected to the fixing screw 13. With the above configuration, the connecting column 2 can be moved by rotating the fixing screw 13. Furthermore, when the connecting column 2 is pressed down, the fixing screw 13 is tightened to fix the connecting column 2. The fixing is convenient and effective.

[0027] In this embodiment, the connecting post 2 is provided with a buffer hole 15, and the rotating shaft 4 is provided with a slider 16. The slider 16 is disposed in the buffer hole 15, and a connecting block 17 is provided at the top of the buffer hole 15. A telescopic rod 18 is provided between the connecting block 17 and the slider 16, and a spring 19 is sleeved on the telescopic rod 18. Through the above arrangement, a buffering effect can be achieved, preventing the connecting post 2 from being pressed down excessively and causing damage to the outer shell. At the same time, a certain pressure can be applied to the outer shell, so that the outer shell can be better fixed on the base 1, which facilitates the processing of the outer shell and prevents the outer shell from shaking and affecting the processing accuracy.

[0028] As one implementation, the connecting column 2 is equipped with a horizontal positioning block 20, which is slidably connected to the connecting column 2. The horizontal positioning block 20 is equipped with a horizontal slot 21, which matches the fixed bracket 3. Through the above settings, the fixed bracket 3 can be horizontally positioned, thus enabling the fixed bracket 3 to have two usage modes. In one mode, the fixed bracket 3 can rotate at any angle, allowing the outer shell to fit well against the plane of the base 1. In the other mode, the fixed bracket 3 can always remain horizontal under the action of the horizontal positioning block 20, making the processing of the outer shell more flexible and diverse, improving processing efficiency and processing effect.

[0029] Specifically, the horizontal slot 21 has a protrusion 22, and the fixed bracket 3 has a recess 23, with the protrusion 22 and the recess 23 matching. This arrangement improves the fit between the horizontal slot 21 and the fixed bracket 3, making it less likely for the horizontal slot 21 to detach from the fixed bracket 3. The protrusion 22 and the recess 23 are generally fitted with an interference fit to enhance usability.

[0030] As one implementation method, the fixed bracket 3 is provided with reinforcing ribs 24. By setting the reinforcing ribs 24, the strength of the fixed bracket 3 can be improved and the service life of the fixed bracket 3 can be extended.

[0031] In use, the connecting column 2 is raised by rotating the fixing screws 13 on both sides, and the fixing brackets 3 on both sides are kept at the same height as much as possible. When the spring 19 in the buffer hole 15 is in a compressed state, the rotation of the fixing screws 13 can be stopped. Then, the outer shell is placed on the base 1, and the clamping screws 8 of the clamping mechanism 6 on both sides are rotated to clamp the base 1. Then, the fixing screws 13 are rotated to move the connecting column 2 down and fix the outer shell with a certain downward pressure for subsequent machining. When the outer shell needs to be flipped, the connecting column 2 is raised to a height that can rotate the fixing bracket 3 to flip the outer shell. Then, the outer shell is flipped. After that, the fixing screws 13 are reversed to move the outer shell down and fix it on the base 1, so as to facilitate the machining of the other side of the outer shell.

[0032] This utility model, by setting a fixed bracket 3 on a connecting column 2, the connecting column 2 having a rotating shaft 4, the fixed bracket 3 having a sleeve 5, the sleeve 5 being fitted onto the rotating shaft 4 and rotatably connected to the rotating shaft 4, and the fixed bracket 3 having a clamping mechanism 6 to clamp the diameter measuring instrument housing, enables the fixed bracket 3 set on the connecting column 2 to be flipped, thereby allowing the diameter measuring instrument housing fixed on the fixed bracket 3 to be flipped, facilitating the processing of both sides of the diameter measuring instrument housing and improving processing efficiency.

[0033] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
