Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a tool angle setting device for a machine tool angle head. Background Technology

[0002] In the field of machining, the angle direction of the cutting tool often needs to be changed frequently during the workpiece machining process. When adjusting the tool direction with a traditional angle head, it is often necessary to repeatedly calibrate the dial indicator and straighten the tool to ensure the accuracy of the angle.

[0003] This process requires highly experienced operators, who need to manually rotate the angle head housing and then confirm the angle using external measuring tools. The adjustment efficiency is not high enough, making it impossible to quickly orient the tool angle in commonly used directions such as 0°, 90°, 180°, and 270°, and it is difficult to ensure the consistency of angle positioning. Utility Model Content

[0004] The purpose of this invention is to provide a tool angle quick setting device for machine tool angle heads, which can realize quick and accurate tool angle setting, especially for commonly used angles such as 0°, 90°, 180°, and 270°, which can simplify the operation process and ensure positioning accuracy.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tool angle quick setting device for a machine tool angle head, comprising an angle head and an angle adjustment base fixed to the outer wall of the angle head, wherein a tool mounting seat is rotatably connected to the angle adjustment base via a rotating shaft, a rotating ring is fixed to the outer wall of the tool mounting seat, and a quick positioning structure capable of quickly positioning the tool mounting seat at a specific angle is provided between the rotating ring and the angle adjustment base;

[0006] The quick positioning structure includes a positioning pin that runs from bottom to top through the angle adjustment base. The top end of the positioning pin is inserted into a rotating ring. The rotating ring has an upper pin hole at a fixed angle for the positioning pin to pass through.

[0007] Preferably, the quick positioning structure further includes a lower pin hole formed on the lower surface of the angle adjustment base, and a pin sleeve is interference-fitted into each lower pin hole. The positioning pin passes into the pin sleeve, and the outer wall of the pin sleeve is provided with a connection structure for fixing the positioning pin and the pin sleeve.

[0008] Preferably, the connection structure includes a set screw and a screw hole. The screw hole is formed on the outer wall of the pin sleeve, and the outer wall of the positioning pin is provided with a flat groove. One end of the set screw is threaded into the screw hole and abuts against the flat groove.

[0009] Preferably, the inner cavity at the bottom of the rotating ring is provided with a groove, the top of the groove is formed with a boss, the upper pin hole is opened on the lower surface of the boss, and the angle adjustment base is provided with a limiting structure for auxiliary limiting of the rotation of the rotating ring.

[0010] Preferably, the limiting structure includes a limiting block, which is arranged in an inverted L shape. A limiting groove is formed between the horizontal plate of the limiting block and the upper surface of the angle adjustment base. The bottom end of the limiting block is fixedly connected to the angle adjustment base by bolts. The lower surface of the rotating ring has an inwardly formed annular edge, which is located in the limiting groove.

[0011] Preferably, the outer wall of the angle adjustment base is provided with a scale mark for indicating the direction and value of the tool angle adjustment, and the positioning pin is located on the 0° scale value of the scale mark.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a quick positioning structure composed of a rotating ring and a positioning pin. Operators do not need to repeatedly calibrate the dial indicator or use external measuring tools. They only need to rotate the tool mounting base to the corresponding angle so that the positioning pin can be inserted into the upper pin hole on the rotating ring to complete the positioning. This can shorten the angle adjustment time. When the upper pin hole is opened at 0°, 90°, 180°, and 270°, it can realize the quick switching of these four commonly used angles.

[0014] 2. The upper pin hole on the rotating ring of this utility model is preset at a fixed angle and is connected with the positioning pin to avoid human error when rotating manually in the traditional way. This ensures the consistency of the tool angle after each adjustment and improves the machining accuracy. The scale markings on the outer wall of the angle adjustment base can directly indicate the adjustment direction and value of the tool angle, and the positioning pin is located at the 0° scale, providing a clear reference for initial positioning and angle calibration, and improving the intuitiveness of operation.

[0021] 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.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a tool angle quick setting device for a machine tool angle head, including an angle head 1 and an angle adjustment base 2 fixed to the outer wall of the angle head 1. The fixed connection ensures the relative stability between the base and the angle head 1 during the angle adjustment process. A tool mounting seat 3 is rotatably connected to the angle adjustment base 2 through a rotating shaft. A rotating ring 4 is fixed to the outer wall of the tool mounting seat 3. The rotating ring 4 rotates synchronously with the tool mounting seat 3. A quick positioning structure 5 is provided between the rotating ring 4 and the angle adjustment base 2, which can quickly position the tool mounting seat 3 at a specific angle. The angle positioning function is transferred to the cooperation between the rotating ring 4 and the base, avoiding positioning errors caused by directly operating the tool mounting seat 3.

[0023] The rapid positioning structure 5 includes a positioning pin 501 that penetrates the angle adjustment base 2 from bottom to top. The top end of the positioning pin 501 is inserted into the rotating ring 4. The rotating ring 4 has an upper pin hole 502 at a fixed angle for the positioning pin 501 to pass through. After passing through the base, the positioning pin 501 is inserted into the upper pin hole 502 of the rotating ring 4. The rotation of the rotating ring 4 is restricted by mechanical insertion, thereby fixing the tool angle. The upper pin hole 502 is set at 0°, 90°, 180°, and 270°. The angle is quickly locked by the insertion, replacing traditional calibration and measuring tools, reducing manual operation steps, and shortening the adjustment time.

[0024] The quick positioning structure 5 also includes a lower pin hole 503 opened on the lower surface of the angle adjustment base 2. Each lower pin hole 503 is interference-fitted with a pin sleeve 504. The pin sleeve 504 is fixed to the lower pin hole 503 by interference fit, providing guidance and support for the positioning pin 501, ensuring that the positioning pin 501 is vertically inserted into the upper pin hole 502. The positioning pin 501 passes through the pin sleeve 504. The outer wall of the pin sleeve 504 is provided with a connection structure for fixing the positioning pin 501 and the pin sleeve 504.

[0025] The connecting structure includes a set screw 505 and a screw hole 506. The screw hole 506 is formed on the outer wall of the pin sleeve 504, and the outer wall of the positioning pin 501 has a flat groove 507. One end of the set screw 505 is threaded into the screw hole 506 and abuts against the flat groove 507. After being screwed into the screw hole 506, the set screw 505 abuts against the flat groove 507 of the positioning pin 501, using friction to fix the position of the positioning pin 501 and prevent the positioning pin 501 from falling off during processing. The detachable set screw 505 structure enables quick fixing and releasing of the positioning pin 501, making operation simple; the flat groove 507 ensures that the force of the set screw 505 is concentrated, avoiding positioning offset caused by the rotation of the positioning pin 501.

[0026] The inner cavity at the bottom of the rotating ring 4 is provided with a groove 508, and a boss 509 is formed on the top of the groove 508. The upper pin hole 502 is opened on the lower surface of the boss 509. The angle adjustment base 2 is provided with a limiting structure 6 for auxiliary limiting of the rotation of the rotating ring 4.

[0027] The limiting structure 6 includes a limiting block 601, which is arranged in an inverted L-shape. A limiting groove 602 is formed between the horizontal plate of the limiting block 601 and the upper surface of the angle adjustment base 2. The bottom end of the limiting block 601 is fixedly connected to the angle adjustment base 2 by bolts. An annular edge 603 is formed inward on the lower surface of the rotating ring 4, and the annular edge 603 is located in the limiting groove 602. The annular edge 603 slides in the limiting groove 602. The limiting block 601 restricts the vertical displacement of the rotating ring 4 through the horizontal plate, allowing it to rotate only around the axis of rotation, thus preventing the rotating ring 4 from axially shifting during rotation.

[0028] The outer wall of the angle adjustment base 2 is provided with a scale mark 510 for indicating the direction and value of the tool angle adjustment, and the positioning pin 501 is located at the 0° scale value of the scale mark 510. The scale mark 510 reflects the rotation angle of the rotating ring 4, and the 0° scale corresponds to the position of the positioning pin 501, serving as the initial positioning reference.

[0029] When in use, when the angle head 1 is installed into the spindle, the tip of the angle head 1 is facing the -X direction. Insert the positioning pin 501 into the pin sleeve 504 until it is aligned with the upper pin hole 502 at 0° inside the rotating ring 4. Screw the set screw 505 into the pin sleeve 504 and tighten it to prevent the positioning pin 501 from falling off during processing.

[0030] When the machining needs to be adjusted to the positive X direction, loosen the set screw 505 and the locking nut on the outer wall of the set screw 505, pull out the positioning pin 501, rotate the housing about 180°, and then insert the positioning pin 501. The positioning pin 501 is aligned with the upper pin hole 502 inserted into the rotating ring 4. At this time, the tool tip is facing the +X direction.

[0031] This structure allows for rapid orientation in four directions, eliminating the need for repeated calibration and straightening after each adjustment. It is simple to operate and greatly saves calibration time.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
