Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of automotive thrust rod processing equipment, specifically, to a drilling machine for processing automotive thrust rods. Background Technology

[0002] As a key component of the automotive suspension system, the machining accuracy of the thrust rod directly affects the stability and safety of the vehicle. With the automotive manufacturing industry's increasing demands for parts production efficiency and quality, traditional drilling methods for automotive thrust rods are gradually revealing their significant shortcomings.

[0003] Currently, general-purpose drilling machines are commonly used in the drilling process of automotive thrust rods. However, due to the irregular shape and special structure of the thrust rod, it is difficult to accurately position and effectively fix it when drilling with a general-purpose drilling machine. This leads to frequent problems such as drilling position deviation and insufficient hole diameter accuracy, seriously affecting product quality. Furthermore, to meet the drilling requirements of different parts of the thrust rod, a large number of tooling fixtures are often required, which not only increases the cost of tooling design, manufacturing, and maintenance, but also consumes a lot of time and manpower during tooling changes, greatly reducing production efficiency. In addition, frequent tooling changes can easily introduce positioning errors, further affecting drilling accuracy and product yield. These drawbacks make traditional drilling methods unable to meet the growing demands of the automotive manufacturing industry for high-efficiency and high-precision production.

[0004] Therefore, developing a drilling machine specifically designed for efficient and precise drilling of automotive thrust rods, reducing reliance on a large number of tooling fixtures, and improving production efficiency has become an urgent problem to be solved in the automotive parts processing field. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a drilling machine for machining automotive thrust rods, which solves the technical problem in the prior art where the thrust rod has an irregular shape and special structure, making it difficult to accurately position and effectively fix it when drilling with a general-purpose drilling machine, resulting in frequent problems such as drilling position deviation and insufficient hole diameter accuracy, which seriously affect product quality.

[0006] According to one aspect, at least one embodiment of this disclosure provides a drilling machine for machining automotive thrust rods, comprising:

[0007] A platform and a base frame, wherein the base frame is fixed to the bottom of the platform;

[0008] A drilling assembly is mounted on the base frame;

[0009] The mounting and fixing components are mounted on the platform;

[0010] The mounting and fixing assembly includes a movable base, which is linearly slidably connected to the surface of the platform. A mounting base is inserted into the movable base, and the mounting base and the movable base are fixedly connected by bolts. A movable frame is linearly driven onto the platform, and the mounting base and the movable frame are fixedly connected by bolts.

[0011] As a further technical solution, the mounting base moves in the same direction as the movable base, and an extension frame is provided on the top of the movable frame. The extension frame is connected to a pair of pressure blocks via a vertical linear drive.

[0012] As a further technical solution, the propulsion drilling assembly includes a rotating disk, which is rotatably connected to the base frame via a rotating shaft. A driven gear is provided on the rotating shaft at the bottom of the rotating disk, and a drive gear driven by electricity is provided on the base frame.

[0013] As a further technical solution, the surface of the rotating disk is provided with a moving platform connected by a linear drive, a high-speed motor is mounted on the moving platform, and a drill bit is provided at the output end of the high-speed motor, with the drill bit located on one side of the mounting base.

[0014] As a further technical solution, a protective plate is provided on the surface of the rotating disk, and a perforation is opened on the surface of the protective plate, with the drill bit located in the perforation.

[0015] As a further technical solution, the groove portion on the surface of the mounting base has a U-shaped opening structure, the bottom surface of the pressure block has an arc-shaped structure, and the pressure block is located directly above the mounting base.

[0016] As a further technical solution, a pair of baffles are provided on the surface of the platform, and the baffles are located at both ends of the movable frame.

[0017] As a further technical solution, the rotating disk can rotate 45° to both sides.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the mounting and fixing assembly allows for flexible adjustment of the mounting position via the linear sliding of the movable seat on the table surface and the linear drive of the movable frame. This adapts to the processing requirements of automotive thrust rods of different specifications and lengths, reducing reliance on numerous tooling fixtures. The mounting seat is secured to the movable seat and movable frame with bolts, ensuring stability and reliability during processing. The U-shaped groove of the mounting seat and the arc-shaped structure of the pressure block work together to firmly fix irregularly shaped thrust rods, preventing displacement during drilling. This effectively solves the problem of precise positioning and effective fixing of thrust rods on general-purpose drilling machines, thereby reducing drilling position deviations and insufficient hole diameter accuracy, and improving product quality and production efficiency.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-4 As shown, a drilling machine for machining automotive thrust rods is illustrated in one embodiment of this disclosure, comprising:

[0033] A platform 1 and a base frame 2, wherein the base frame 2 is fixed to the bottom of the platform 1;

[0034] A drilling assembly 4 is mounted on the base frame 2.

[0035] Mounting and fixing component 3 is mounted on the platform 1;

[0036] The mounting and fixing assembly 3 includes a movable base 3-1, which is linearly slidably connected to the surface of the platform 1. A mounting base 3-2 is inserted and connected to the movable base 3-1, and the mounting base 3-2 is fixedly connected to the movable base 3-1 by bolts. A movable frame 3-3 is linearly driven and connected to the platform 1, and the mounting base 3-2 is fixedly connected to the movable frame 3-3 by bolts. The mounting base 3-2 and the movable base 3-1 move in the same direction. An extension frame 3-4 is provided on the top of the movable frame 3-3, and a pair of pressure blocks 3-5 are vertically linearly driven and connected to the extension frame 3-4.

[0037] In some examples, to achieve precise positioning and secure fixing of thrust rods of different specifications, a mounting and fixing component 3 is designed. The movable seat 3-1 is slidably connected to the frame 1 via a linear guide rail and can move freely along the transverse X-axis. The slot on its surface and the protrusion on the bottom of the mounting seat 3-2 form an insert fit. After tightening with bolts, the mounting seat 3-2 can be quickly replaced to fit different thrust rod sizes. The linear drive device (such as an electric push rod or cylinder) on the frame 1 can drive the movable frame 3-3 to move in the same direction, so that the transverse position adjustment range of the mounting seat 3-2 covers a variety of drilling requirements. For example, when machining thrust rods of different lengths, only the positions of the movable seat 3-1 and the movable frame 3-3 need to be adjusted to change the transverse coordinates of the drilling point.

[0038] The extension frame 3-4 at the top of the movable frame 3-3 is connected to a pair of pressure blocks 3-5 via a vertical linear drive (such as a hydraulic cylinder). When the thrust rod is placed on the mounting base 3-2, the pressure blocks 3-5 press down vertically, and the anti-slip texture on their surface fits tightly against the surface of the thrust rod, forming a rigid clamp. This allows for the rapid replacement and positioning of thrust rods of different specifications. It can adapt to the processing requirements of different hole diameters at both ends of the thrust rod, and through lateral adjustment, ensure that the drilling position perfectly matches the design drawings, avoiding an increase in scrap rate due to positioning deviations.

[0039] like Figures 1-4 As shown in the figure, the present embodiment proposes that the propulsion drilling assembly 4 includes a rotating disk 4-1, which is rotatably connected to the base frame 2 via a rotating shaft. A driven gear 4-2 is provided on the rotating shaft at the bottom of the rotating disk 4-1, and a drive gear 4-3 driven by electricity is provided on the base frame 2. A moving platform 4-4 is provided on the surface of the rotating disk 4-1 and is connected to it by a linear drive. A high-speed motor 4-5 is installed on the moving platform 4-4, and a drill bit 4-6 is provided at the output end of the high-speed motor 4-5. The drill bit 4-6 is located on one side of the mounting base 3-2.

[0040] In some examples, to achieve multi-angle drilling of the thrust rod, a propulsion drilling assembly 4 is designed. This assembly includes a rotating disk 4-1 supported by a bottom rotating shaft connected to the base frame 2. The driven gear 4-2 on the rotating shaft meshes with the drive gear 4-3. When the drive gear 4-3 is driven to rotate by a motor, different drilling angles can be adjusted. The moving stage 4-4 on the surface of the rotating disk 4-1 moves back and forth along the X-axis through a linear drive device (such as a lead screw). The high-speed motor 4-5 mounted on the moving stage 4-4 drives the drill bit 4-6 to rotate at high speed. When the moving stage 4-4 advances forward, the drill bit 4-6 cuts into the thrust rod to complete the drilling.

[0041] For example, when machining a thrust rod with multi-angle mounting holes, the drive gear 4-3 first rotates the rotary table 4-1 to a preset angle, and then the moving table 4-4 controls the feed depth of the drill bit 4-6 to ensure that the hole position is perpendicular to the mounting surface of the thrust rod. The rotation function of the rotary table 4-1 avoids the errors caused by manually adjusting the workpiece angle in traditional drilling machines, and is especially suitable for machining oblique holes or annular distributed holes. The coordinated control of linear drive and rotary drive meets the stringent requirements for hole position accuracy in automotive thrust rods.

[0042] For example, such as Figure 1 As shown, a protective plate 5 is provided on the surface of the rotating disk 4-1, and a perforation 6 is opened on the surface of the protective plate 5. The drill bit 4-6 is located in the perforation 6.

[0043] In some examples, the protective plate 5 on the surface of the rotary table 4-1 cooperates with the drill bit 4-6 through perforations 6 to form a safety barrier. The protective plate 5 is made of high-strength metal, and the diameter of the perforations 6 on its surface is only slightly larger than the outer diameter of the drill bit 4-6. When the drill bit 4-6 is advanced with the moving table 4-4 to drill, the perforations 6 provide a precise guiding channel for the drill bit 4-6, while blocking splashing iron filings and coolant. The precise size design of the perforations 6 does not affect the normal feed of the drill bit 4-6, and can effectively reduce machining noise and improve the overall operating stability of the drilling machine.

[0044] For example, such as Figure 1 As shown, the groove on the surface of the mounting base 3-2 has a U-shaped opening structure, the bottom surface of the pressure block 3-5 has an arc-shaped structure, and the pressure block 3-5 is located directly above the mounting base 3-2.

[0045] In some examples, the U-shaped groove of the mounting base 3-2 and the arc-shaped bottom surface of the pressure block 3-5 form a complementary clamping structure. The U-shaped opening design can accommodate thrust rods with different cross-sectional shapes, such as round and square rods, which can be embedded in the groove to achieve multi-angle fit. The bottom surface of the arc-shaped pressure block 3-5 tightly covers the top of the thrust rod, and the two work together to form a three-point contact, evenly distributing the clamping force. For example, when the pressure block 3-5 is pressed down under vertical linear drive, the arc-shaped structure can adapt to the curvature of the rod, ensuring that the thrust rod does not shift during drilling, while avoiding surface indentations caused by local stress concentration, thus ensuring the workpiece machining accuracy and appearance quality.

[0046] For example, such as Figure 1 As shown, a pair of baffles 7 are provided on the surface of the platform 1, and the baffles 7 are located at both ends of the movable frame 3-3.

[0047] In some examples, the shield 7 on the surface of the frame 1 provides lateral protection and debris interception for the moving frame 3-3. The shield 7, made of transparent acrylic or metal mesh, is installed at both ends of the moving frame 3-3, its height and width covering the travel range of the moving frame 3-3. This prevents metal chips or coolant splashed during drilling from entering the transmission components of the moving frame 3-3. For example, when the moving frame 3-3 moves laterally to adjust the drilling position, the shield 7 always follows and protects, preventing metal chips from entangled in the transmission structure and causing jamming. The transparent material allows operators to observe the processing status, while the metal mesh material enhances the protective strength and extends the service life of critical equipment components.

[0048] For example, such as Figure 1 As shown, the rotating disk 4-1 can rotate 45° to both sides.

[0049] In some examples, the rotary table 4-1 has a 45° rotation range to the left and right, allowing for flexible multi-angle machining. This angle design balances the requirements for machining angled holes in thrust rods with the stability of the equipment structure, and the rotational accuracy is controlled by a servo motor and a precision reducer. For example, when machining a thrust rod with an inclined mounting hole, the rotary table 4-1 can quickly rotate to the required angle, and the linear feed of the moving table 4-4 completes the angled hole drilling.

[0050] In actual use: Place the automotive thrust rod in the U-shaped groove of the mounting base 3-2. Select a suitable mounting base 3-2 according to the specifications of the thrust rod and insert it into the movable base 3-1. Fix the mounting base 3-2 and the movable base 3-1 with bolts. At the same time, adjust the position of the movable frame 3-3 through the linear drive device on the platform 1 so that the mounting base 3-2 is in a suitable processing position. Then fix the mounting base 3-2 and the movable frame 3-3 with bolts. Next, start the vertical linear drive device of the extension frame 3-4 to move a pair of pressure blocks 3-5 downward. Use the arc-shaped structure surface of the bottom of the pressure block 3-5 to cooperate with the U-shaped groove of the mounting base 3-2 to firmly fix the thrust rod. Then, the drive gear 4-3 of the drilling assembly 4 is activated. The drive gear 4-3 drives the driven gear 4-2 at the bottom of the rotating disk 4-1 to rotate, so that the rotating disk 4-1 rotates to the required drilling angle. Then, the linear drive device on the surface of the rotating disk 4-1 is activated, which drives the moving table 4-4 to move, so that the drill bit 4-6 at the output end of the high-speed motor 4-5 on the moving table 4-4 is aligned with the drilling position of the thrust rod. The high-speed motor 4-5 is activated, so that the drill bit 4-6 rotates at high speed and performs drilling. During the drilling process, the protective plate 5 plays a protective role. After the drilling is completed, each drive device is operated in reverse order to make the drill bit 4-6 retract, the rotating disk 4-1 reset, and the pressure block 3-5 rise. Finally, the bolts between the mounting base 3-2 and the moving base 3-1 are removed, and the processed thrust rod is taken out.
