Description

Technical Field

[0001] The utility model belongs to the technical field of tool holders, and particularly relates to an angle-adjustable tool holder device. Background Art

[0002] In the processing of offshore oil components, there are many ring groove products with different internal and external angles, and most of them are very hard to process after clad welding. For the processing of ring grooves with different angles, the traditional method is to obliquely install the machining tool on the CNC electric tool rest after measuring with an angle gauge. The disadvantage of this clamping method is that after the tool is obliquely installed, the M20×50 high-strength square tool rest screw has less contact area on the clamping surface and insufficient clamping force when clamping the tool. During the processing, the tool moves, resulting in scrapping of the product. If an externally purchased customized adjustable angle tool holder and tool are used, not only the order period is long, the cost is high, but also the delivery time is seriously affected, which in turn seriously affects the higher cycle and causes heavy losses. Therefore, in view of the above problems, it is necessary to make improvements. Content of the Utility Model

[0025] An angle-adjustable tool holder device, such as Figures 1-7As shown in the figure, it includes a tool holder 3. The tool holder 3 is fixed to the numerically controlled electric tool rest 1 in an angle-adjustable manner, or the tool holder 3 is fixed to the numerically controlled electric tool rest 1 in an angle-adjustable manner through a tool shank 2. According to the machining types of the inner ring groove and the outer ring groove, the tool holder 3 is fixed to the numerically controlled electric tool rest 1 in an angle-adjustable manner or is installed on the tool shank 2 connected to the numerically controlled electric tool rest 1 in an angle-adjustable manner, so as to realize the machining of different types of ring grooves, and increase the angle adjustment range when the tool is installed obliquely; a guide groove 7 is formed on the outer side wall of the tool holder 3, and a tool 4 whose inner end rod part is adapted to the guide groove 7 is installed on the tool holder 3 in an angle-adjustable manner. Installing the tool 4 on the tool holder 3 in an angle-adjustable manner provides conditions for the angle adjustment of the tool 4 and realizes the machining of ring grooves with different diameters; wherein, the inner end rod part of the tool 4 is a four-sided structure adapted to the guide groove 7, and this structure can prevent the tool 4 from rotating.

[0026] One end of the tool holder 3 is in a fan-shaped structure and the other end is in a rod-shaped structure, and the guide groove 7 is arranged on the outer arc surface of the tool holder 3; specifically, an angle scale line 11 is formed on the outer arc surface of the tool holder 3 at the position of one side edge of the guide groove 7, which is convenient for quickly and accurately adjusting the inclination angle of the tool 4. Designing the outer side surface of the tool holder 3 as an outer arc surface provides conditions for anti-interference adjustment when the tool 4 rotates around the hinge center, and ensures reliable support for the tool 4 when the tool 4 is fixed at different angles;

[0027] The angle-adjustable installation structure of the tool 4 on the tool holder 3 is specifically as follows: the rod part of the tool 4 is hinged to the tool holder 3 through a positioning pin 5, which provides conditions for the rotation of the tool 4 around the hinge pin 5. One or more arc-shaped waist holes 9 concentric with the hinge center of the tool 4 and vertically communicating with the guide groove 7 are formed on one side plate surface of the tool holder 3. The tool 4 is fixed to the tool holder 3 in an angle-adjustable manner through a screw 6 that passes through the arc-shaped waist hole 9 and is adapted to the threaded hole of the rod part of the tool 4. When adjusting the angle of the tool 4, the screw 6 in the loose state moves along the corresponding arc-shaped waist hole 9. When the angle of the tool 4 is adjusted, only the screw 6 needs to be tightened. The fixing structure of the tool 4 is stable and reliable, the pre-tightening pressure is controllable, and the problem of workpiece scrapping caused by the displacement of the tool 4 is effectively avoided.

[0028] On the basis of the above technical features, such as Figures 1-4As shown in the figure, an installation groove 10 extending inward is formed on the outer end face of the tool shank 2. The other end rod part of the tool holder 3 is adaptively inserted into the installation groove 10, and the tool holder 3 is tightly fixed to the outer end part of the tool shank 2 by a plurality of setscrews 8 threadedly connected to the upper end face of the tool shank 2. Among them, the other end rod part of the tool holder 3 is a quadrilateral structure with edges, which can effectively avoid the drawback of rotation and displacement after being adapted to the installation groove 10. Grooves are machined on the upper and lower end faces of the inner end of the tool shank 2 facing the numerical control electric tool rest 1, so that a T-shaped connection part is formed on the side of the inner end part of the tool shank 2 facing the numerical control electric tool rest 1. The T-shaped connection part at the inner end of the tool shank 2 is adaptively inserted and connected with the numerical control electric tool rest 1. The tool shank 2 is threadedly connected to the numerical control electric tool rest 1, and the plurality of setscrews 8 for tightening the tool shank 2 are fixed to the numerical control electric tool rest 1 in an angle-adjustable manner; among them, the rod-shaped part of the tool holder 3 is a quadrilateral structure adapted to the installation groove 10. Under the pressing action of the plurality of setscrews 8, reliable anti-rotation and anti-displacement fixation of the tool holder 3 is realized, solving the problem of product scrapping caused by the displacement of the tool 4 during the processing of the ring groove. While ensuring the reliable fixation of the tool 4, the product yield and processing efficiency are improved;

[0029] As Figures 5-7 shown, the other end rod part of the tool holder 3 is adaptively inserted and connected with the numerical control electric tool rest 1. The tool holder 3 is threadedly connected to the numerical control electric tool rest 1, and the plurality of setscrews 8 for pressing against the other end rod part of the tool holder 3 fix the tool holder 3 to the numerical control electric tool rest 1 in an angle-adjustable manner. Among them, a plurality of setscrews 8 are evenly distributed around the numerical control electric tool rest 1, and the fixed position of the tool holder 3 on the numerical control electric tool rest 1 can be adjusted according to the installation angle of the tool holder 3. The rod part of the tool holder 3 adapted to the numerical control electric tool rest 1 is a quadrilateral structure. Under the pressing action of the plurality of setscrews 8, reliable anti-rotation and anti-displacement fixation of the tool holder 3 on the numerical control electric tool rest 1 is realized, solving the problem of product scrapping caused by the displacement of the tool 4 during the processing of the ring groove. While ensuring the reliable fixation of the tool 4, the product yield and processing efficiency are improved.

[0030] In this structure: 1) When turning the outer ring groove: The tool holder 3 is directly installed on the numerical control electric tool rest 1. After the tool 4 (grooving tool) is connected to the tool holder 3 through the φ8 internal thread positioning pin 5, the angle is rotated and adjusted. The angle adjustment range is between 0° and 90°. After the angle adjustment of the tool 4 is completed, the grooving tool needs to be tightened by the screw 6 (M10×25 high-strength square tool rest screw); 2) When boring the inner ring groove: The tool holder 3 is directly installed on the tool shank 2, and then the tool shank 2 is installed on the numerical control electric tool rest 1. After the tool 4 (grooving tool) is connected to the tool holder 3 through the φ8 internal thread positioning pin 5, the angle is rotated and adjusted. The adjustment range is between 0° and 90°. After the angle adjustment of the tool 4 is completed, the tool 4 (grooving tool) needs to be tightened by the screw 6 (M10×25 high-strength square tool rest screw).

[0031] The installation structure of this technical solution is stable and reliable, avoiding the drawback of the ring groove shifting during the processing, improving the finished product rate of product processing, shortening the processing cycle, reducing the processing cost, and ensuring the delivery time.
