Description

Technical Field

[0001] This utility model belongs to the technical field of drilling devices, specifically relating to a drilling device for processing a rocker seat. Background Technology

[0002] In the field of machining, rocker seats, as a common mechanical connection component, typically require precise drilling during manufacturing to facilitate subsequent assembly and fixation. Currently, drilling for rocker seats mainly relies on traditional drilling equipment or CNC machine tools. Traditional drilling methods usually require manual positioning, fixing, and adjustment of the workpiece, which is cumbersome. Furthermore, inaccurate positioning can easily lead to hole misalignment, affecting the product's machining accuracy. In addition, manual adjustment and drilling are inefficient in batch processing, making it difficult to meet the needs of large-scale production.

[0003] Existing rocker-type drilling equipment typically suffers from the following problems:

[0004] 1. Inaccurate positioning affects processing accuracy: When drilling, existing equipment often relies on manual adjustment or simple fixtures for positioning, which can easily lead to hole position deviation due to operational errors, affecting product consistency and assembly accuracy.

[0005] 2. Low processing efficiency, making it difficult to meet the needs of mass production: Traditional single-head punching methods require processing one by one, which cannot achieve simultaneous multi-point punching, resulting in a long processing cycle and reduced production efficiency.

[0006] 3. Inconvenient waste disposal, affecting the working environment: Drilling generates a large amount of metal waste. If not cleaned up in time, it may affect the normal operation of the equipment and even lead to a decrease in processing accuracy. Existing equipment often lacks an effective waste collection and disposal mechanism, requiring frequent shutdowns for cleaning, which increases the complexity of operation. Utility Model Content

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a drilling device for rocking seat processing. It can improve the accuracy and production efficiency of drilling processing by optimizing the workpiece positioning method, improving drilling efficiency and improving the waste collection method, and improving the working environment to meet the needs of mass production.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A drilling device for processing a rocking seat includes a worktable and a rocking seat body. Columns are fixed on the upper surface of the worktable near the left and right sides. Two drilling heads that can perform downward drilling operations are arranged above the worktable. A bidirectional lead screw that drives the two drilling heads to move relative to each other and a guide rod that guides the movement of the two drilling heads are installed between the left and right columns.

[0010] The upper surface of the workbench is provided with two positioning seats, one in front and one behind, for positioning the front and rear ends of the rocking seat body. The positioning seats are fixed to the workbench using screws and pins.

[0011] The workbench has a discharge structure in the center, and a waste collection component is installed on the lower surface of the workbench at the position corresponding to the discharge structure.

[0012] Furthermore, the upper surface of the positioning seat is provided with a positioning groove for positioning the end part of the rocking seat body, and a clearance groove is provided on the side of the upper surface of the positioning seat away from the rocking seat body.

[0013] Furthermore, fixing plates are fixed on both the left and right sides of the positioning seat, and a positioning hole for cooperating with the pin is opened in the center of the fixing plate.

[0014] Furthermore, the material discharge structure is a discharge port located in the middle of the workbench, and the upper surface of the workbench has pin holes that mate with the pins.

[0015] Furthermore, the waste collection assembly includes a guide frame aligned with the discharge port, the guide frame being U-shaped with an opening to the left, and a collection box being provided on the inner side of the guide frame, a stop edge extending inward being fixed to the lower edge of the guide frame, and a fixing edge extending outward being fixed to the upper edge of the guide frame.

[0016] Furthermore, the punch head includes a vertical guide seat, a moving block that cooperates with the guide rod and the double-acting screw is fixed on one side of the guide seat, and a lifting seat is slidably installed on the other side of the guide seat. A punching motor is fixed at the upper end of the lifting seat, and a chuck is fixed through the output shaft of the punching motor. A drill bit is clamped at the lower end of the chuck, and an electric cylinder that drives the lifting seat to move up and down is fixed at the upper end of the guide seat.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model provides a drilling device for the rocker seat processing. By optimizing the workpiece positioning method, improving drilling efficiency, and improving the waste collection method, it enhances the accuracy and production efficiency of drilling processing and improves the working environment to meet the needs of mass production.

[0019] This invention employs a positioning seat to precisely position the front and rear ends of the rocker body, ensuring that the ends of the rocker body are stably placed within the positioning groove. The clearance groove also prevents interference at the ends, thereby improving the workpiece's installation accuracy. The positioning seat is fixed to the worktable with screws and pins, and the fixing plate tightly engages with the pins through positioning holes, ensuring that the rocker body does not shift during drilling. This avoids hole position deviations caused by inaccurate positioning, thus improving the product's assembly accuracy and consistency.

[0020] This invention employs a bidirectional lead screw and guide rod to drive two drilling heads, enabling them to move synchronously and align with the predetermined drilling position on the rocker base, thus achieving simultaneous drilling by both heads. Compared to the traditional single-head drilling method, this solution effectively shortens processing time and improves production efficiency. Furthermore, the drilling motor drives the lifting base precisely via an electric cylinder, ensuring the drill bit can complete the drilling operation stably, avoiding hole diameter errors caused by uneven feed, and improving drilling quality.

[0021] To address the impact of large amounts of metal shavings generated during drilling on the working environment and equipment stability, this invention incorporates a discharge structure at the center of the workbench and a waste collection assembly below it. The discharge port quickly guides the metal shavings into the guide frame, preventing accumulation on the workbench and reducing manual cleaning workload. The collection box can hold a certain amount of metal shavings and can be removed via a pull-out mechanism for rapid cleaning, thereby improving production continuity, enhancing the working environment, and ensuring long-term stable equipment operation.

[0022] Through the above-mentioned optimized structure, this utility model enables the drilling device for rocker seat processing to have the characteristics of high precision, high efficiency and convenient cleaning, which can effectively improve the processing quality of rocker seats, meet the needs of mass production, and reduce the complexity of manual intervention, and has broad application prospects.

[0030] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. Example

[0031] like Figure 1 As shown, a drilling device for processing a rocker seat includes a worktable 1 and a rocker seat body 8. The worktable 1 is made of high-strength alloy steel to improve the overall load-bearing capacity and stability. Columns 4 are fixed to the upper surface of the worktable 1 near the left and right sides. The columns 4 are solid structures with rectangular cross-sections, providing sufficient rigid support. The bottoms of the columns 4 are firmly connected to the worktable 1 with bolts, ensuring the stability of the overall structure. Two drilling heads 5 are installed above the worktable 1 for downward drilling operations. The drill bits 57 of the drilling heads 5 are made of high-speed steel or hard alloy material to ensure... To ensure the wear resistance and high efficiency of the drilling, a bidirectional lead screw 7 is installed between the two left and right columns 4 to drive the relative movement of the two drilling heads 5. The bidirectional lead screw 7 adopts a T-type thread design to improve transmission efficiency and accuracy. Both ends of the bidirectional lead screw 7 are installed on the inner side of the column 4 through rolling bearings, thereby reducing rotational friction resistance and improving the smoothness of the movement of the drilling head 5. In addition, a guide rod 6 is also installed between the two left and right columns 4 to guide the movement of the two drilling heads 5. The guide rod 6 adopts a high-precision linear guide and is processed by precision grinding to ensure the smooth movement and accurate positioning of the drilling head 5.

[0032] The upper surface of the workbench 1 is provided with two positioning seats 9, which are used to position the front and rear ends of the rocking seat body 8. The main body of the positioning seat 9 is made of high-strength aluminum alloy to reduce weight and improve corrosion resistance. The bottom of the positioning seat 9 is provided with multiple evenly distributed mounting holes. It is fixed to the workbench 1 with high-strength screws and reinforced with pins to enhance positioning accuracy, so as to ensure that no positional shift occurs during the drilling process, thereby improving drilling accuracy. The positioning seat 9 is fixed to the workbench 1 by screws and pins, thereby improving the stability of the equipment and being able to adapt to long-term, high-frequency batch drilling operations.

[0033] The center of the workbench 1 is equipped with a discharge structure, which adopts a stepped ramp design to reduce the accumulation of waste and guide its smooth discharge. The lower surface of the workbench 1 is equipped with a waste collection component 2 at the position corresponding to the discharge structure. The waste collection component 2 can effectively collect the metal shavings generated during the drilling process, prevent waste from clogging or scattering, and improve the service life of the equipment and the cleanliness of the working environment.

[0034] like Figure 2 As shown, the upper surface of the positioning seat 9 is provided with a positioning groove 92 for positioning the end part of the rocker seat body 8. The width and depth of the positioning groove 92 are precisely calculated to adapt to rocker seat bodies 8 of different specifications and to ensure their stability after placement. In addition, a clearance groove 91 is provided on the side of the upper surface of the positioning seat 9 away from the rocker seat body 8. The size design of the clearance groove 91 can match the structure of the end of the rocker seat body 8 so that it will not interfere with the drilling operation after positioning, thereby improving the overall processing accuracy.

[0035] The positioning base 9 is fixed with a fixing plate 93 on both the left and right sides. The fixing plate 93 is made of thickened stainless steel plate to improve durability and impact resistance. The center of the fixing plate 93 is provided with a positioning hole 94 that cooperates with the pin. The diameter of the positioning hole 94 is strictly matched with the pin and is precision CNC machined to ensure high-precision positioning after installation and effectively prevent the rocking base body 8 from undergoing slight displacement during processing.

[0036] like Figure 3 As shown, the discharge structure is a discharge port 120 located in the middle of the workbench 1. The edges of the discharge port 120 are chamfered to reduce the accumulation of metal scrap. At the same time, the opening angle of the discharge port 120 is optimized to ensure that the drilling scrap can fall smoothly into the collection box 21 below. The upper surface of the workbench 1 is provided with a pin hole 110 that mates with the pin. The inner wall of the pin hole 110 is precision ground to reduce wear and ensure the stability of the pin installation.

[0037] like Figure 4As shown, the waste collection assembly 2 includes a guide frame 22 aligned with the discharge port 120. The guide frame 22 is made of high-strength engineering plastic or stainless steel to prevent long-term accumulation of metal scraps and subsequent wear. The guide frame 22 is U-shaped with an opening to the left. The U-shaped structure can effectively guide the scraps into the collection box 21 and prevent the scraps from scattering to other areas of the workbench 1. The collection box 21 is located inside the guide frame 22. The capacity of the collection box 21 is optimized to store a certain amount of metal scraps, and it is detachable for easy regular cleaning and replacement. An inwardly extending baffle 23 is fixed to the lower edge of the guide frame 22. The baffle 23 prevents the scraps from overflowing during discharge and improves the concentration of the discharge. In addition, an outwardly extending fixing edge 24 is fixed to the upper edge of the guide frame 22. The fixing edge 24 can enhance the overall rigidity of the guide frame 22 and provide additional installation and fixing functions to prevent loosening during use.

[0038] like Figure 5 As shown, the punch head 5 includes a vertical guide seat 52, which is made of high-strength cast iron to improve structural strength and stability, and is manufactured using high-precision machining to ensure motion accuracy. A moving block 51, which cooperates with the guide rod 6 and the double-acting lead screw 7, is fixed to one side of the guide seat 52. The moving block 51 is made of wear-resistant alloy material and coated with a lubricating coating to reduce frictional resistance and extend service life. A lifting seat 55 is slidably mounted on the other side of the guide seat 52. The lifting seat 55 has a precision ball bearing guide rail inside to ensure the smoothness and accuracy of the lifting motion. A punching motor 54 is fixed to the upper end of the lifting seat 55. The punching motor 54 is a high-precision motor with a rated power of 750W. A servo motor provides stable and reliable rotational power; the output shaft of the drilling motor 54 passes through the lifting seat 55 and is fixed with a chuck 56. The chuck 56 adopts an elastic clamping mechanism and can be adapted to different specifications of drill bits to meet the drilling needs of different specifications of the rocker body 8; the lower end of the chuck 56 is clamped with a drill bit 57, which is made of carbide material with a diameter range of 3mm-10mm to ensure efficient drilling and long service life; the upper end of the guide seat 52 is fixed with an electric cylinder 53 that drives the lifting seat 55 to rise and fall. The electric cylinder 53 adopts a high-precision linear drive mechanism, which can complete precise lifting and falling in a short time and ensure the stable feed of the drill bit 57 during the drilling process, thereby improving processing accuracy and efficiency. Example

[0039] This embodiment provides a drilling process for precisely positioning the rocker body 8 using positioning seats 9. First, two positioning seats 9, made of 6061 aluminum alloy, are installed on the upper surface of the worktable 1. The positioning seats 9 are fixed to the worktable 1 with four M8 high-strength bolts and are precisely positioned using pins to ensure stability. Before drilling, the operator places the front and rear ends of the rocker body 8 into the positioning grooves 92 of the two positioning seats 9, and accurately positions the semi-cylindrical structure at the end of the rocker body 8 into the clearance groove 91. The clearance groove 91 is sized to match the outer diameter of the end of the rocker body 8 by ±0.05mm to ensure positioning stability and accuracy. After the workpiece is fully inserted, the fixing plate 93 is fixed with pins. The gap between the pins and the positioning holes 94 is controlled within 0.02mm to prevent slight displacement of the workpiece during drilling.

[0040] Comparative Cases:

[0041] In traditional processes, operators typically use manual clamps to fix workpieces on a platform. However, the clamping force of these clamps is affected by human intervention, leading to errors in positioning accuracy. This is especially problematic in batch processing, where it is difficult to guarantee consistent positioning accuracy for each workpiece. In contrast, this embodiment employs a fixed plate 93 in conjunction with pin positioning, which not only improves positioning accuracy but also simplifies operation, reduces human error, and results in higher consistency in batch processing. Example

[0042] This embodiment provides a drilling device in which a bidirectional lead screw 7 drives a drilling head 5 to move synchronously. The device uses a 20mm diameter, 5mm pitch T-type bidirectional lead screw 7, with a nitrided surface to improve hardness and wear resistance. Both ends of the bidirectional lead screw 7 are mounted in bearing seats of the column 4, using 6203ZZ double-row ball bearings to ensure low friction and high stability during rotation. A servo motor (model: 750W, rated speed 3000rpm) drives the lead screw 7 to rotate, causing the drilling heads 5 on both sides to move synchronously along the guide rod 6, thus ensuring that both drill bits 57 can drill the workpiece simultaneously. The guide rod 6 is made of 40Cr hardened steel and undergoes high-precision grinding, with a straightness error of less than 0.01mm, ensuring a smooth movement trajectory of the drilling head 5.

[0043] Comparative Cases:

[0044] In traditional processes, the punch head 5 often uses a single head to punch holes one by one, resulting in low punching efficiency. This is especially true when the workpiece requires multiple holes, as repositioning is necessary each time, impacting production efficiency. In contrast, this embodiment uses a bidirectional lead screw 7 to synchronously drive two punch heads 5, enabling simultaneous processing of two holes and improving processing efficiency by at least 50%, making it suitable for mass production. Example

[0045] This embodiment provides a highly efficient waste chip collection system to solve the problem of difficult cleaning of metal waste generated during drilling. The workbench 1 has a discharge port 120 with a diameter of 80mm at its center. The edges of the discharge port 120 are chamfered at C1.5 to reduce waste chip accumulation and optimize the discharge path. The waste collection assembly 2 includes a guide frame 22 and a collection box 21. The guide frame 22 is made of 304 stainless steel with a wear-resistant and rust-proof coating and is designed in a U-shape to allow waste chips to flow smoothly into the collection box 21. The collection box 21 measures 200mm × 150mm × 100mm and has a removable filter screen inside for regular cleaning of fine metal debris. The collection box 21 can be pulled out via a sliding rail structure made of self-lubricating POM engineering plastic to reduce friction and improve the smoothness of removal.

[0046] Comparative Cases:

[0047] In traditional drilling operations, waste chips typically accumulate on the worktable, requiring operators to periodically clean them with an air gun or brush. This process is time-consuming and labor-intensive, and can easily lead to waste chips entering the guide rails or lead screw structure, affecting equipment operation. In contrast, this embodiment uses a waste collection component 2, which can directly guide waste chips into the collection box 21, reducing manual cleaning work, improving production efficiency, and preventing waste chips from entering moving parts, thus extending the equipment's service life. Example

[0048] This embodiment provides a high-precision drilling mechanism using an electric cylinder 53 to drive a lifting seat 55. The electric cylinder 53 is a linear electric cylinder with a rated thrust of 500N and a stroke of 100mm, and is equipped with a high-precision grating ruler feedback system, achieving a positioning accuracy of ±0.02mm. The drilling motor 54 is a 1.2kW high-speed servo motor with a maximum speed of 24000rpm, suitable for high-precision drilling requirements. The electric cylinder 53 uses closed-loop control, which can adjust the feed rate in real time according to the workpiece material and drilling depth, ensuring that the drill bit 57 maintains stable feed during drilling and avoiding hole diameter errors caused by cutting force fluctuations. In addition, the chuck 56 is an ER16 high-precision spring chuck with a clamping accuracy within 0.005mm, ensuring that the drill bit 57 does not wobble during rotation and improving drilling quality.

[0049] Comparative Cases:

[0050] Traditional drilling equipment often uses cylinder-driven lifting mechanisms, but cylinders typically have low stroke accuracy and are greatly affected by air pressure fluctuations, making it difficult to maintain consistent drilling depth. In contrast, this embodiment uses an electric cylinder 53 to drive the lifting seat 55, which, with the support of a high-precision control system, can achieve stable and accurate feed control, improving drilling consistency and accuracy. It is particularly suitable for processing workpieces with strict hole depth requirements.

[0051] The working principle of this utility model is as follows: When drilling the rocking seat body 8, the front and rear ends of the rocking seat body 8 are respectively placed in the positioning grooves 92 of the two positioning seats 9, and the semi-cylindrical ends of the front and rear ends of the rocking seat body 8 are respectively placed in the relief grooves 91 in the front and rear positioning seats 9, thereby completing the rapid positioning when drilling the positioning seats 9.

[0052] During the drilling operation, the drive motor 3 drives the bidirectional lead screw 7 to rotate, and the bidirectional lead screw 7 drives the two drilling heads 5 to align with the position to be drilled on the rocker seat body 8. At this time, drilling can be performed. The two drilling heads 5 drill at the same time and cooperate with the positioning seat 9 for rapid positioning, which greatly improves the efficiency of drilling and is conducive to batch drilling.

[0053] The waste generated from drilling will be discharged into the inside of the collection box 21 through the discharge port 120, so that the workbench 1 does not need to be cleaned. The collected waste is then processed by pulling out the collection box 21, making it easier to clean up the drilling waste.

[0054] When the punch head 5 is punching, the punching motor 54 drives the drill bit 57 to rotate. At this time, the electric cylinder 53 drives the lifting seat 55 to descend, thereby driving the drill bit 57 to descend and perform the punching work.

[0055] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
