[0058] A drilling assembly, wherein two groups of the drilling assemblies are symmetrically arranged and used for drilling holes on the left and right sides of the piston;

[0059] A three-axis driving assembly 27 is used to drive the first drilling power head 3 to move up and down, left and right, and forward and backward;

[0060] The chuck 2 is rotatably mounted on the machine body 1 , the first drilling power head is fixedly mounted on the machine body 1 via a first driving assembly, and two groups of drilling assemblies are fixedly mounted on the machine body 1 and are located on the left and right sides of the chuck 2 , respectively.

[0061] In the present technical solution, by setting up a first drilling power head 3 and a drilling assembly, when the piston needs to be drilled, the piston is placed in the chuck 2, and the chuck 2 is pneumatic. After the piston to be drilled is placed in the chuck 2, the piston is clamped by starting the pneumatic chuck 2, and then the first drilling power head 3 is started (the working principle of the drilling power head is the existing technology, and no further elaboration is made here), which can drive the drill bit of the first drilling power head 3 to rotate;

[0062] The three-axis driving assembly 27 can drive the first drilling power head 3 to move up and down, left and right, or forward and backward, thereby driving the drill bit of the first drilling power head 3 to move up and down, left and right, or forward and backward, and drilling holes at different positions above the piston can be performed by moving the drill bit;

[0063] At the same time, holes can be drilled on the left and right sides of the piston through two symmetrically arranged drilling components.

[0064] Through this structural design, by setting up a first drilling power head 3, a three-axis drive assembly 27 and two symmetrically arranged drilling assemblies, multi-directional drilling of the piston can be achieved through one device, and the top and left and right sides of the piston can be drilled through the cooperation of the first drilling power head 3, the three-axis drive assembly 27 and two symmetrically arranged drilling assemblies, thereby reducing the number of processes and personnel and improving production efficiency. Example 2

[0065] This embodiment provides a composite drilling machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0066] Furthermore, the three-axis driving assembly 27 includes:

[0067] A base 5 is fixedly mounted on the machine body 1;

[0068] An X-direction sliding saddle 6 is used to drive the first drilling power head 3 to move left and right along the X direction;

[0070] The Z-direction sliding saddle 8 is used to drive the first drilling power head 3 to move up and down along the Z direction;

[0071] Among them, the first drilling power head 3 is fixedly connected to the Z-direction saddle 8, the Z-direction saddle 8 is set on the Y-direction saddle 7 for up and down movement through the Z-direction drive component 11, the Y-direction saddle 7 is set on the X-direction saddle 6 for forward and backward movement through the Y-direction drive component 10, and the X-direction saddle 6 is set on the base 5 for left and right movement through the X-direction drive component 9.

[0072] In the present technical solution, since an X-direction slide saddle 6, a Y-direction slide saddle 7 and a Z-direction slide saddle 8 are provided, the horizontal angle between the X-direction slide saddle 6 and the Y-direction slide saddle 7 is 90°, the Z-direction slide saddle 8 and the Y-direction slide saddle 7 are provided vertically, and since the first drilling power head 3 is fixedly connected to the Z-direction slide saddle 8, the Z-direction slide saddle 8 is provided on the Y-direction slide saddle 7 by moving up and down through the Z-direction drive assembly 11, the Y-direction slide saddle 7 is provided on the X-direction slide saddle 6 by moving forward and backward through the Y-direction drive assembly 10, and the X-direction slide saddle 6 is provided on the base 5 by moving left and right through the X-direction drive assembly 9;

[0073] When the first drilling power head 3 needs to move left and right along the X direction, the X-direction driving assembly 9 arranged on the base 5 is started to drive the X-direction sliding saddle 6 to move along the X direction. Since the X-direction sliding saddle 6 is connected to the Y-direction sliding saddle 7 through the Y-direction driving assembly 10, and the Y-direction sliding saddle 7 is connected to the Z-direction sliding saddle 8 through the Z-direction driving assembly 11, when the X-direction driving assembly 9 drives the X-direction sliding saddle 6 to move along the X direction, the Y-direction sliding saddle 7 can be driven to move along the X direction, so that the Y-direction sliding saddle 7 drives the Z-direction sliding saddle 8 to move along the X direction, so that the Z-direction sliding saddle 8 drives the first drilling power head 3 to move along the X direction;

[0074] When the first drilling power head 3 needs to move forward and backward along the Y direction, the Y-direction driving assembly 10 arranged on the X-direction sliding saddle 6 is started, so that the Y-direction driving assembly 10 can drive the Y-direction sliding saddle 7 to move forward and backward along the Y direction, thereby making the Y-direction sliding saddle 7 drive the Z-direction sliding saddle 8 to move along the Y direction, thereby driving the first drilling power head 3 on the Z-direction sliding saddle 8 to move along the Y direction;

[0075] When the first drilling power head 3 needs to move up and down in the Z direction, the Z-direction driving assembly 11 arranged on the Y-direction sliding saddle 7 is started, so that the Z-direction driving assembly 11 can drive the Z-direction sliding saddle 8 to move up and down in the Z direction, thereby making the Z-direction sliding saddle 8 drive the first drilling power head 3 to move up and down in the Z direction;

[0076] In summary, the first drilling power head 3 can realize the position change of the drill bit of the first drilling power head 3 on the X, Y, and Z coordinates through the cooperation of the X-direction sliding saddle 6, the Y-direction sliding saddle 7, and the Z-direction sliding saddle 8 with the X-direction driving assembly 9, the Y-direction driving assembly 10, and the Z-direction driving assembly 11;

[0077] At the same time, the first drilling power head 3 can change its position independently in the X, Y, and Z axes, or it can realize simultaneous changes in the X, Y, and Z coordinates through multi-axis linkage. A control computer 26 is also fixedly arranged on the outside of the body 1. The control computer 26 has a built-in numerical control system. The numerical control system can be programmed to realize multi-axis linkage of the three-axis drive assembly 27, thereby driving the first drilling power head 3 to move according to the program, and the first drilling power head 3 can also be driven by the control computer 26 to change its position independently in the X, Y, and Z axes.

[0078] Through this structural design, by setting up a three-axis drive assembly 27, the first drilling power head 3 can move left and right, front and back, and up and down on the X-axis, Y-axis, and Z-axis respectively, so that the first drilling power head 3 can change the drilling position through three-axis linkage, thereby achieving drilling in more parts above the piston and reducing the drilling process of the piston. Example 3

[0079] This embodiment provides a composite drilling machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0080] Furthermore, the X-direction component includes:

[0081] The screw rod 12 is fixedly rotatably arranged in the base 5;

[0082] The slide rail 13 is fixedly arranged on the base 5;

[0083] A servo motor 14 is fixedly arranged outside the base 5, and an output shaft of the servo motor 14 is fixedly connected to one end of the screw rod 12;

[0084] The X-direction slide saddle 6 is arranged on the slide rail 13 to move left and right through a slider, and the X-direction slide saddle 6 is arranged for transmission with the lead screw 12 .

[0085] In the present technical solution, since a screw rod 12, a slide rail 13, and a servo motor 14 are provided, when it is necessary to drive the X-axis slide saddle 6 to move left and right along the X-axis, it is only necessary to start the servo motor 14, so that the servo motor 14 can drive the screw rod 12 to rotate. Since the X-axis slide saddle 6 and the screw rod 12 are arranged for transmission, and the X-axis slide saddle 6 is arranged on the slide rail 13 for left and right movement through a slider, when the screw rod 12 rotates, the X-axis slide saddle 6 can be driven to move by the screw rod 12. At the same time, the cooperation between the slider and the slide rail 13 makes the movement of the X-axis slide saddle 6 smoother.

[0086] Through this structural design, by setting up the screw rod 12, the slide rail 13 and the servo motor 14, the X-axis slide saddle 6 can be conveniently moved left and right along the X-axis through the X-axis drive component 9. The base 5, the screw rod 12, the slide rail 13 and the servo motor 14 form an electric slide, which is convenient for driving the object to perform automatic linear motion. Example 4

[0087] This embodiment provides a composite drilling machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

Example 5

[0090] This embodiment provides a composite drilling machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0091] Furthermore, the drilling assembly comprises:

[0092] The second drilling power head 15 is used to drill a hole on the left side of the piston;

[0093] A base 16, wherein the base 16 is fixedly disposed on the machine body 1, and the base 16 and the second drilling power head 15 are both located on the left side of the chuck 2;

[0094] The second slide saddle 17 is used to drive the second drilling power head 15 to move left and right along the X direction;

[0095] The second drilling power head 15 is fixedly arranged on the second slide saddle 17 , and the second drive assembly 18 having the same structure as the X-axis drive assembly 9 is fixedly arranged on the base 16 , and the second slide saddle 17 and the screw rod 12 of the second drive assembly 18 are arranged for transmission.

[0096] In the present technical solution, when it is necessary to drill a hole on the left side of the piston, the second drilling power head 15 is started, and then the second driving component 18 is driven. Since the second driving component 18 is arranged in the same structure as the X-direction driving component 9, the second driving component 18 and the second saddle 17 and the base 16 form an electric slide structure, so that when the second driving component 18 is started, the servo motor 14 of the second driving component 18 is started first, so that the screw rod 12 and the slider of the second driving component 18 can drive the second saddle 17 to move left and right along the X direction through transmission, thereby driving the second drilling power head 15 to move left and right along the X direction, thereby driving the drill bit of the second drilling power head 15 to approach or disengage from the piston, thereby realizing drilling of the piston.

[0097] Since the drilling assembly is provided with two groups, which are respectively located on the left and right sides of the piston, when it is necessary to drill holes on both sides of the piston, the second drilling power head 15 and the second driving assembly 18 of the drilling assembly located on both sides of the piston can be started;

[0098] At the same time, programming can also be performed in the control computer 26 to control the X-axis displacement of the second drilling power head 15 through the numerical control program of the control computer 26, and the multi-axis linkage of the second drilling power head 15 and the first drilling power head 3 can be achieved through the numerical control program of the control computer 26.

[0099] Through this structural design, by setting up a drilling assembly, it is convenient to drill holes on the top of the piston through the first drilling power head 3, and at the same time, the left and right sides of the piston can be drilled through the second drilling power head 15 of the symmetrically arranged drilling assembly, which saves time and process steps, improves work efficiency, and avoids repeated clamping. Example 6

[0100] This embodiment provides a composite drilling machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0101] Furthermore, the second drilling power head 15 is a dual-axis drill bit.

[0102] Through this structural design, since the second drilling power head 15 is a dual-axis drill bit, multiple holes can be processed at the same time, which increases the processing efficiency, reduces the processing hours of the same piston, and improves the economic benefits. Example 7

[0103] This embodiment provides a composite drilling machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0104] Furthermore, it also includes:

[0105] A support plate 19 is located above the machine body 1, and the chuck 2 is rotatably disposed on the support plate 19;

[0106] An angle motor 20, which is fixedly arranged at the lower end of the support plate 19 and is used to drive the chuck 2 to rotate;

[0107] The third saddle 21 is used to drive the support plate 19 to move up and down along the Z direction;

[0108] The third saddle 21 drives the support plate 19 to move up and down through the guide assembly;

[0109] A third drive assembly 22 having the same structure as the Z-direction drive assembly 11 is fixedly disposed in the machine body 1 , and the third saddle 21 is in transmission arrangement with the screw rod 12 of the third drive assembly 22 .

[0110] In the present technical solution, since the support plate 19 and the angle motor 20 are provided, the chuck 2 can be rotated by the angle motor 20, so that the rotation angle of the chuck 2 can be adjusted, and thus the rotation angle of the piston can be adjusted, so that the second drilling head can drill holes on different angle surfaces of the piston, so that the processing range is larger;

[0111] Since the third slide saddle 21 and the third drive assembly 22 are provided, when the Z-direction coordinate of the piston needs to be changed, and the third drive assembly 22 is provided with the same structure as the Z-direction drive assembly 11, the third slide saddle 21 can be moved up and down in the Z direction by the third drive assembly 22, so that the third slide saddle 21 can drive the support plate 19 to move up and down in the Z direction through the guide assembly, thereby driving the chuck 2 to move up and down in the Z direction, so that the piston moves up and down in the Z direction;

[0112] The Z-direction movement of the chuck 2 can also be programmed into the numerical control program by controlling the computer 26, so as to realize the multi-axis linkage of the Z-direction movement of the chuck 2, the X-direction movement of the second drilling power head 15 and the X-, Y- and Z-direction movement of the first drilling power head 3, thereby realizing the following processing steps:

[0113] 1. Place the piston to be processed on chuck 2, and start chuck 2 to clamp the piston;

[0114] 2. The first drilling power head 3 is moved downward in the Z direction by the three-axis driving assembly 27 to drill a hole in the piston. After drilling, the first drilling power head 3 is raised in the Z direction to drive the drill bit to leave the hole. Then, the three-axis driving assembly 27 is used to change the X and Y positions of the first drilling power head 3 to drill a hole, thereby achieving drilling at different X and Y positions above the piston;

[0115] 3. Start the drilling assembly, so that the two symmetrical second drilling power heads 15 move toward the two sides of the piston respectively. The second drilling power heads 15 are double-axis drill heads, so that the two symmetrical second drilling power heads 15 can drill 4 holes at one time, greatly improving the work efficiency;

[0116] 4. At the same time, the chuck 2 can be rotated by the angle motor 20, or moved up and down by the third drive assembly 22, thereby driving the piston to rotate or move up and down, or it can rotate and move up and down at the same time, so that the second drilling power head 15 can drill holes on the piston at different heights and angles.

[0117] Through the above method, multi-axis linkage is carried out, so that one device can realize multi-directional drilling, which is highly efficient, saves equipment, site, personnel, processing procedures, and greatly increases the processing speed.

[0118] Through this structural design, by setting up the support plate 19, the angle motor 20, the third saddle 21 and the third drive assembly 22, it is convenient to drive the chuck 2 to rotate the angle or move up and down, thereby driving the piston to rotate the angle or move up and down, so that the second drilling power head 15 can drill the piston at different heights and different angles.
