[0002] In modern industrial systems, mechanical parts, as the basic units constituting mechanical equipment, directly determine the performance, reliability, and service life of the equipment through their processing quality and efficiency. They play a crucial supporting role in the development of numerous fields such as aerospace, automobile manufacturing, energy equipment, and medical devices. Drilling machines are among the most commonly used processing equipment in the machining of mechanical parts, primarily used for drilling, reaming, and countersinking operations.

[0003] For example, utility model application CN202110502706.8 discloses a drilling machine for machining mechanical parts. This utility model, through its device, can be adjusted according to the size of different mechanical parts, and can clamp mechanical parts of different thicknesses using a fixing clamp, further improving the fixing effect of the device and thus improving the machining accuracy of the mechanical parts. However, it can only achieve simple fixing of parts. When drilling holes in special locations such as inclined surfaces or curved surfaces of the parts is required, the operator usually needs to adjust the clamping position of the parts multiple times, which is cumbersome and consumes a lot of time and manpower.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a drilling machine for machining mechanical parts. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling machine for machining mechanical parts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling machine for machining mechanical parts, comprising a frame and a support plate. A drill bit body is installed at the top center of the frame, and a clamping assembly is installed at the middle of the frame. A drive shaft is provided at the front center of the clamping assembly, and a synchronous pulley is sleeved on the outside of the drive shaft. A synchronous pulley is connected to the outside of the synchronous pulley via a synchronous belt, and a drive shaft passes through the middle of the synchronous pulley. A gear is sleeved on the rear end of the drive shaft, and a rack is connected to the bottom of the gear. A cylinder is installed at the left end of the rack, and the support plate is located in front of the rack.

[0007] Furthermore, the clamping assembly includes a fixed base, a servo motor, and a ball screw, with the ball screw rotatably connected to the front end of the fixed base, and the other end of the ball screw connected to the servo motor, which is located in the middle of the back of the frame.

[0008] Furthermore, the clamping assembly also includes a lead screw nut and a fixing plate, and the ball screw is externally connected to the lead screw nut, and the lead screw nut is externally provided with a fixing plate.

[0009] Furthermore, the clamping assembly also includes a first link and a second link, with the first link hinged to the middle of the fixing plate and the second link hinged to the other end of the first link.

[0010] Furthermore, the clamping assembly also includes a third link and a clamping arm, and the third link is hinged to the openings on the left and right sides of the fixing seat, and the clamping arm is hinged to the other end of the third link.

[0011] Furthermore, the second and third links are parallel to each other, and the two ends of the second link are hinged to the fixed seat and the clamping arm, respectively.

[0012] Furthermore, the cylinder is located inside the lower part of the frame, and the frame and the support plate are fixedly connected.

[0013] Furthermore, the first transmission shaft is disposed in the bearing at the opening above the surface of the support plate, and the second transmission shaft is disposed in the bearing at the opening below the surface of the support plate.

[0014] This utility model provides a drilling machine for machining mechanical parts, which has the following advantages:

[0015] 1. The operation of the cylinder in this utility model will drive the rack to move laterally, thereby transmitting power through the meshing of the rack and gear to make the second transmission shaft rotate. Through the meshing of the synchronous belt with the first and second synchronous pulleys, the power is transmitted to make the first transmission shaft rotate. This enables the angle adjustment of the mechanical parts on the clamping assembly, allowing the drilling machine to perform multi-angle machining of the mechanical parts without having to adjust the clamping position of the mechanical parts multiple times, which greatly improves the flexibility of machining.

[0016] 2. The servo motor of this utility model drives the ball screw to rotate, causing the screw nut and the fixing plate to move along the length of the ball screw. This, in turn, drives the first connecting rod, the second connecting rod, and the third connecting rod to rotate and support the clamping arms. This allows the left and right clamping arms to move closer or further apart to accommodate mechanical parts of different sizes, greatly improving the versatility of the drilling machine.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 3 As shown, a drilling machine for machining mechanical parts includes a frame 1 and a support plate 4. A drill bit body 2 is installed in the middle of the top of the frame 1, and a clamping assembly 3 is installed in the middle of the frame 1. A drive shaft 5 is provided in the middle of the front end of the clamping assembly 3, and a synchronous pulley 6 is sleeved on the outside of the drive shaft 5. A synchronous pulley 8 is connected to the outside of the synchronous pulley 6 through a synchronous belt 7, and a drive shaft 9 is passed through the middle of the synchronous pulley 8. A gear 10 is sleeved on the rear end of the drive shaft 9, and a rack 11 is connected to the bottom of the gear 10. A cylinder 12 is installed on the left end of the rack 11. The support plate 4 is located in front of the rack 11, and the cylinder 12 is located in the lower part of the frame 1. The frame 1 and the support plate 4 are fixedly connected. The drive shaft 5 is located in a bearing at the opening above the surface of the support plate 4, and the drive shaft 9 is located in a bearing at the opening below the surface of the support plate 4.

[0023] The specific operation is as follows: the operation of cylinder 12 will drive rack 11 to move laterally, thereby transmitting power through the meshing of rack 11 and gear 10 to make drive shaft 9 rotate. Through the meshing of synchronous belt 7 with synchronous pulley 6 and synchronous pulley 8 respectively, power is transmitted to make drive shaft 5 rotate. This enables the angle adjustment of mechanical parts on clamping assembly 3, allowing the drilling machine to perform multi-angle machining of mechanical parts without having to adjust the clamping position of mechanical parts multiple times, greatly improving the flexibility of machining.

[0024] like Figure 2As shown, the clamping assembly 3 includes a fixed base 301, a servo motor 302, and a ball screw 303. The ball screw 303 is rotatably connected to the front end of the fixed base 301, and the other end of the ball screw 303 is connected to the servo motor 302. The servo motor 302 is located in the middle of the back of the frame 1. The clamping assembly 3 also includes a screw nut 304 and a fixing plate 305. The screw nut 304 is connected to the outside of the ball screw 303, and the fixing plate 305 is provided on the outside of the screw nut 304. The clamping assembly 3 also includes a first connecting... The clamping assembly 3 also includes a third link 308 and a clamping arm 309. The third link 308 is hinged to the openings on the left and right sides of the fixing base 301. The clamping arm 309 is hinged to the other end of the third link 308. The second link 307 and the third link 308 are parallel to each other. The two ends of the second link 307 are respectively hinged to the fixing base 301 and the clamping arm 309.

[0025] The specific operation is as follows: the servo motor 302 drives the ball screw 303 to rotate, causing the screw nut 304 and the fixing plate 305 to move along the length of the ball screw 303, thereby driving the first connecting rod 306, the second connecting rod 307, and the third connecting rod 308 to rotate and support the clamping arm 309, so that the left and right clamping arms 309 move closer or further apart to adapt to mechanical parts of different sizes, greatly improving the versatility of the drilling machine.

[0026] In summary, when using this drilling machine for machining mechanical parts, the part to be processed is first placed on the fixed base 301, and then the servo motor 302 is started. The servo motor 302 drives the ball screw 303 to rotate, which drives the screw nut 304 to make linear displacement. This causes the angle of the first connecting rod 306 to change slowly, which drives the second connecting rod 307 and the third connecting rod 308 to rotate, causing the clamping arms 309 to move closer to each other until the two clamping arms 309 press against both sides of the part to be processed. This effectively limits the displacement and shaking of the part during the processing and ensures the processing accuracy of the part.

[0027] Then, the drill body 2 is started to process the mechanical parts. After completing one hole, if it is necessary to drill holes at other positions or angles of the parts, the cylinder 12 is started. The cylinder 12 extends or retracts, driving the rack 11 to move laterally. The rack 11 meshes with the gear 10 to transmit power, causing the transmission shaft 9 and the synchronous pulley 8 to rotate. The synchronous pulley 8 meshes with the synchronous belt 7 to transmit power, causing the synchronous pulley 6, the transmission shaft 5, and the clamping assembly 3 to rotate, thus adjusting the angle of the mechanical parts. This allows the drill press to perform multi-angle processing of the mechanical parts without having to adjust the clamping position of the mechanical parts multiple times, greatly improving the flexibility of processing.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
