The tool changer arm of a CNC machine tool is a mechanical structure similar to an arm, mainly composed of a mechanical arm, a driver, a clamping mechanism, etc. The main function of the tool changer arm is to automatically replace the worn tool during the machining process to ensure the machining quality and efficiency. When the tool changer arm is being machined, it needs to be drilled, and some holes are deep holes, so it needs to be fixed with tooling.

[0003] The utility model patent with the authorization announcement number CN204430831U discloses a fixture for deep hole processing, including a cylinder body, which is a hollow quadrangular prism, and the two opposite side walls of the cylinder body are provided with a plurality of side-by-side screw holes, in which a stud is screwed, and the stud passes through the screw hole, and the stud is located at one end inside the cylinder body and connected to an abutment block, and the stud is located at one end outside the cylinder body and fixed with a tightening nut.

[0004] However, the above patent has the following shortcomings:

[0005] The above patent fixes the workpiece through multiple studs and abutment blocks. However, when the tool change arm is actually processed, deep hole processing is required at both ends of the tool change arm. Ordinary deep hole processing tooling cannot be turned over, and the tooling needs to be replaced and the workpiece needs to be clamped twice, which is inefficient. At the same time, the positioning effect of the above patent is poor, which reduces the processing accuracy of the tool change arm. Contents of utility model

[0036] Please refer to Figures 1-4 , the present utility model provides a technical solution: a tooling for deep hole machining of a tool arm, including a tooling component 1. The tooling component 1 includes a bottom plate 11, a support plate 16 is installed on the bottom wall of the bottom plate 11, a semi-circular external gear ring 161 is installed on the outer wall of the support plate 16, a support component 2, which includes a "U"-shaped base 21. The two inner walls of the base 21 are rotatably connected to the support plate 16 through a connecting shaft 211. A driving motor 22 is fixedly installed on the base 21, and a transmission gear 221 meshing with the external gear ring 161 is installed at the output end of the driving motor 22.

[0037] Among them, the drive motor 22 drives the support plate 16 to rotate through gear transmission, thereby flipping the bottom plate 11, facilitating the adjustment of the angle of the tool change arm, and facilitating deep hole machining of the end of the tool change arm. The support plate 16 is supported by two connecting shafts 211.

[0038] Arc-shaped grooves 162 are provided on the outer walls on both sides of the support plate 16. Threaded rods 23 are threadedly connected to the outer walls on both sides of the base 21. A handwheel 231 is installed at one end of the threaded rod 23, and a top block 232 is installed at the other end. The top block 232 is slidably connected to the arc-shaped groove 162.

[0039] Among them, holding the handwheel 231 drives the threaded rod 23 to rotate, causing the top block 232 to move horizontally, making it contact the inner wall of the arc-shaped groove 162, thereby fixing the support plate 16 and preventing the bottom plate 11 from vibrating during drilling, with higher stability.

[0040] A plurality of cushion blocks 12 are detachably installed on the bottom plate 11 through bolts. Moreover, a plurality of fixing bolts 131 are threadedly installed on the bottom plate 11. A pressing plate 13 is sleeved on the fixing bolts 131, and a locking nut 132 is threadedly connected to the fixing bolts 131.

[0041] Furthermore, the tool change arm is supported by the cushion blocks 12, facilitating chip removal during the drilling of the tool change arm. The pressing plate 13 is placed on the surface of the tool change arm. The locking nut 132 rotates on the fixing bolt 131, thereby fixing the pressing plate 13 and making the pressing plate 13 contact the upper surface of the tool change arm to prevent the tool change arm from loosening during drilling.

[0042] A plurality of positioning pins 14 are threadedly connected to the bottom plate 11. The plurality of positioning pins 14 are evenly distributed on the bottom plate 11. A plurality of sliding grooves 111 are provided on the bottom plate 11. A limiting frame 112 is installed in each of the plurality of sliding grooves 111. A sliding column 151 is slidably connected in the sliding groove 111. A limiting column 15 is installed on the sliding column 151. Moreover, a telescopic rod 152 is installed on the sliding column 151. The telescopic rod 152 is slidably connected to the limiting frame 112. A spring 153 is sleeved on the telescopic rod 152. One end of the spring 153 abuts against the sliding column 151, and the other end abuts against the limiting frame 112.

[0043] Specifically, the limiting column 15 is used in cooperation with the positioning pin 14. The installation position of the tool change arm is restricted by the positioning pin 14. One end of the tool change arm abuts against the positioning pin 14, and the other end abuts against the limiting column 15. When the limiting column 15 is squeezed, the sliding column 151 is driven to slide in the sliding groove 111, causing the telescopic rod 152 to slide on the limiting frame 112, thereby squeezing the spring 153. The spring 153 drives the sliding column 151 to reset by its own elasticity, making the sliding column 151 reset, facilitating the placement of the tool change arm between the positioning pin 14 and the sliding column 151, and restricting the installation position of the tool change arm, improving its installation accuracy.

[0044] The lower surface of the base 21 is fixedly installed with a base 212, and two connecting grooves 213 are formed in the base 212.

[0045] It should be noted that the base 21 is installed on the workbench of the machine tool by passing a mating bolt through the connecting groove 213 and tightened with a nut, which is applicable to the workbenches of different machine tools.

[0046] The working principle and usage process of the present utility model: Please refer to Figures 1-4 , the installation position of the tool changing arm is restricted by the positioning pin 14. One end of the tool changing arm abuts against the positioning pin 14, and the other end abuts against the limiting column 15. When the limiting column 15 is squeezed, the sliding column 151 slides in the sliding groove 111, causing the telescopic rod 152 to slide on the limiting frame 112, thereby squeezing the spring 153. The elastic force of the spring 153 drives the sliding column 151 to reset, facilitating the placement of the tool changing arm between the positioning pin 14 and the sliding column 151 and restricting the installation position of the tool changing arm, improving its installation accuracy. The tool changing arm is supported by the cushion block 12, facilitating chip removal during the drilling of the tool changing arm. The pressing plate 13 is placed on the surface of the tool changing arm, and the locking nut 132 rotates on the fixing bolt 131 to fix the pressing plate 13, making the pressing plate 13 abut against the upper surface of the tool changing arm to prevent the tool changing arm from loosening during drilling. The driving motor 22 drives the support plate 16 to rotate through gear transmission, and then the bottom plate 11 flips, facilitating the adjustment of the angle of the tool changing arm and facilitating deep hole machining of the end of the tool changing arm. Holding the handwheel 231 and rotating the threaded rod 23 drives the top block 232 to move horizontally, making it abut against the inner wall of the arc-shaped groove 162, thereby fixing the support plate 16 and preventing the bottom plate 11 from vibrating during drilling, with higher stability.

[0047] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
