Description

Technical Field

[0001] This utility model relates to the field of power tool holder processing technology, specifically a universal tool holder auxiliary adjustment and locking mechanism. Background Technology

[0002] Currently, the angle adjustment valves of universal tool holders on the market are locked with three screws after rotation indexing. The angle position after rotation indexing is stabilized entirely by the locking between the screws and the angle valve. This locking method can only withstand a very limited torque load, and angle deviation is very likely to occur during processing. As a result, the processing accuracy and performance of the product are seriously affected.

[0003] Furthermore, the current market's universal tool holder products all use manual rotation of the housing for indexing. This rotation method has two drawbacks: firstly, it is difficult to operate; secondly, the angle positioning is inaccurate; it often requires repeated adjustments, resulting in the scrapping of machined parts. As a result, it causes great inconvenience and economic losses to users.

[0004] Therefore, a universal tool holder auxiliary adjustment and locking mechanism is needed to address this problem. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary adjustment and locking mechanism for a universal tool holder. This utility model is simple, convenient and quick to operate, saves time and effort, and has strong practicality.

[0006] This utility model is implemented as follows:

[0007] A universal tool holder auxiliary adjustment and locking mechanism includes a universal tool holder body, a housing rotation adjustment mechanism on the universal tool holder body, and a housing locking mechanism adjacent to the housing rotation adjustment mechanism on the universal tool holder body.

[0008] The gearbox steering adjustment mechanism includes a steering scale on the universal tool holder body, and a scale alignment plate is attached to the steering scale on the universal tool holder body; the gearbox steering adjustment mechanism includes a steering column fixedly connected to the bottom wall of the tool holder body on one side of the steering scale, and a first gear is threadedly rotatably mounted on the steering column; a hexagonal nut is fixedly connected to the first gear, and the hexagonal nut is threadedly connected to the steering column.

[0009] An angle adjustment valve is rotatably mounted on the side of the universal tool holder body adjacent to the steering column. The angle adjustment valve is connected to a housing within the universal tool holder body. A second gear is mounted on the angle adjustment valve, and the first gear meshes with the second gear. The housing locking mechanism includes a screw threaded into the housing on one side of the angle adjustment valve. A nut is mounted on the screw, and pressure blocks are located on both sides of the screw below the nut. One of the pressure blocks abuts against the angle adjustment valve. The side wall of the pressure block abutting against the angle adjustment valve is sloped.

[0010] Furthermore, a butterfly-shaped spring is abutting the bottom of the pressure block against the inner bottom of the housing. The butterfly-shaped spring facilitates loosening the screw before angle adjustment, allowing the pressure block to pop out and facilitating angle adjustment of the angle adjustment valve.

[0011] Furthermore, the operating principle of this utility model is as follows:

[0012] In this application, when adjusting the angle, the nut on the first gear is adjusted by wrench, allowing the first gear to rotate freely around the positioning column. The first gear meshes with the second gear on the angle adjustment valve, and rotating the first gear drives the angle adjustment valve to rotate. The angle adjustment valve drives the housing to rotate, and the scale values ​​on the steering dial and scale alignment plate are read to obtain accurate angle positioning. This avoids the problem of inaccurate positioning caused by manually rotating the angle adjustment valve in the traditional method.

[0013] Before adjusting the angle of the angle regulating valve, loosen the screw to a loose state. After adjusting the angle of the angle regulating valve, due to the elastic force of the disc spring, the pressure block disengages from the angle regulating valve and moves to the left. Finally, tighten the screw so that the pressure block presses the angle regulating valve at an angle. Through the friction between the pressure block and the angle regulating valve, the angle position of the housing is stabilized.

[0014] Compared with the prior art, the advantages of this utility model are: the rotation accuracy is high, the locking operation is convenient, it can stably position the angle of the angle adjustment valve, the operation is simple, convenient and quick, saving time and effort, and it is highly practical.

[0022] The gearbox steering adjustment mechanism includes a steering scale 12 mounted on the universal tool holder body 1, and a scale alignment plate 11 attached to the steering scale 12 on the universal tool holder body 1; the gearbox 4 steering adjustment mechanism includes a steering column 20 fixedly connected to the inner bottom wall of the tool holder body 1 on one side of the steering scale 12, and a first gear 21 threadedly mounted on the steering column 20; a hexagonal nut is fixedly connected to the first gear 21, and the hexagonal nut is threadedly connected to the steering column 20.

[0023] An angle adjustment valve 30 is rotatably mounted on the side adjacent to the steering column inside the universal tool holder body 1. The angle adjustment valve 30 is connected to a housing 4 within the universal tool holder body 1. A second gear is mounted on the angle adjustment valve 30, and the first gear 21 meshes with the second gear. The locking mechanism of the housing 4 includes a screw 31 threadedly connected to the inside of the housing on one side of the angle adjustment valve.
