Description

Technical Field

[0001] This invention relates to the field of automotive rocker arm machining technology, and in particular to an automatic drilling machining equipment and drilling method for steering rocker arms. Background Technology

[0002] As a key connecting and force-transmitting component of the automotive steering system, the steering rocker arm typically has mounting holes at both ends and is connected to the steering gear output shaft or other linkage mechanisms via a spline structure. Due to the numerous processes involved in its manufacturing and the wide variety of equipment required, the production of rocker arms is quite challenging.

[0003] In existing machining processes, drilling and spline milling of steering rocker arms are usually completed in steps on different machine tools. For example, drilling of the two end holes is completed on a rocker arm drilling machine first, and then the spline is milled on a milling machine. During this process, the steering rocker arm needs to be repeatedly positioned on the drilling machine and the milling machine. This multi-equipment, multi-process machining method not only leads to a complex production process and low efficiency, but also easily introduces errors during the repeated clamping and positioning of the workpiece, affecting the coaxiality and positional accuracy of the product, and making it difficult to guarantee the consistency of machining quality.

A plurality of the card plates are fixed to the bottom of the pull plate, and the card plates are movably engaged with the inner cavity of the adjacent card slot.

[0014] A drilling method for an automatic drilling machine with a steering rocker arm includes the following steps: Step 1: Based on the length of the processed steering rocker arm, pull the pull tubes on both sides of the second bearing seat to move its locking plate out of the inner cavity of the adjacent locking slot. After adjusting the distance between the first bearing seat and the second bearing seat, release the pull tubes. Through the elasticity of the tension spring, the locking plate can be locked into the inner cavity of the locking slot in the relative state, so that the distance between the second bearing seat and the first bearing seat is fixed. Step 2: Based on the width of both ends of the steering rocker arm being processed, rotate the double-acting screws on the first and second bearing seats respectively, so that the slider can drive the two first chucks and two second chucks to perform clamping action, so that one end of the steering rocker arm can be locked between the two first chucks in the opposite state, and the other end can be locked between the two second chucks. By installing the drill rod at the bottom of the rotating shaft sleeve, drive the spindle box to lift and lower, so that the drill rod in the driving state can drill holes at both ends of the steering rocker arm. Step 3: After drilling is completed, remove the drill rod from the rotating sleeve. By turning the locking bolt on the rotating sleeve, the positioning sleeve can be flipped. Pull the adjustment component to rotate the adjustment sleeve and the T-shaped rod, and move the positioning sleeve to the bottom of the rotating sleeve. Pull the retaining ring and adjust the height of the T-shaped rod so that the positioning block can be fitted into the outer wall of the rotating sleeve. Under the influence of gravity, the through block is inserted into the inner cavity of the mounting hole on the rotating sleeve, and the milling component at the bottom of the positioning rod can rotate at an angle. Step 4: Drive the shaft motor so that its second gear drives the first gear to rotate, so that the milling cutter can rotate. Through the lifting and moving of the rocker arm, the milling cutter can perform spline milling on the steering rocker arm that is locked on the first and second bearing seats. At the same time, through the drive of the hydraulic telescopic rod, the bearing plate can be lifted up, which can clean the top of the base plate.

[0015] The technical effects and advantages of this invention are as follows: This invention utilizes a combination of connecting mechanism, milling mechanism, and auxiliary mechanism. By assembling and disassembling the rotating shaft sleeve with the normal drill rod and installing the rotating shaft sleeve with the milling mechanism, the drilling and spline milling of the steering rocker arm can be completed on the same machine. This effectively reduces the number of workpiece transfers and repeated clamping. Furthermore, the auxiliary mechanism facilitates the clamping and limiting of steering rocker arms of different lengths, avoiding errors caused by repeated clamping and positioning, thus improving processing efficiency and ensuring processing accuracy.

[0016] This invention enables quick and convenient connection and separation of the milling mechanism and the drilling spindle through the limiting and adjusting components on the connecting mechanism. When not in use, the milling mechanism can be flipped to a non-working position to avoid interference with drilling. The function switching is flexible and efficient, avoiding the loss of parts or repeated disassembly and assembly, and facilitating the execution of different machining processes on the steering rocker arm, thereby improving machining efficiency and quality.

[0017] This invention uses a clamping assembly driven by a bidirectional lead screw on the first and second bearing seats of the auxiliary mechanism to firmly clamp the two ends of a steering rocker arm of different sizes. At the same time, through the cooperation of the fixing component and the slot, the distance between the two bearing seats can be quickly adjusted and locked to adapt to the clamping requirements of workpieces of different lengths. It has strong versatility and avoids repeated positioning of the steering rocker arm.

[0018] This invention utilizes a combination of a milling mechanism and a base mechanism. The positioning component can be movably engaged with the rotating sleeve of the drilling machine, allowing the spindle's power and rotational motion to be directly transmitted to the milling cutter. This enables precise milling of splines at different angles, expanding the equipment's processing capabilities. Furthermore, the hydraulic telescopic rod in the base mechanism can drive the lifting and lowering of the support plate, facilitating simultaneous force application at the processing end and bottom end of the steering rocker arm, improving processing efficiency. It also facilitates the exposure and cleaning of accumulated debris inside the equipment, maintaining a clean working area and reducing maintenance difficulty. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides, for example Figures 1-10 The diagram shows an automatic drilling machine for a steering rocker arm and its drilling method.

[0032] Example 1 includes a radial drilling mechanism 100, a base mechanism 200, a connecting mechanism 300, a milling mechanism 400, and an auxiliary mechanism 500. The radial drilling mechanism 100 is a conventional radial drilling machine structure. The base mechanism 200 is installed at the bottom of the radial drilling mechanism 100. The connecting mechanism 300 is installed at one end of the radial drilling mechanism 100. The connecting mechanism 300 is used to achieve detachable and detachable connection with the rotating end of the radial drilling mechanism 100. The milling mechanism 400 is installed at the bottom of the connecting mechanism 300. The milling mechanism 400 is used to cooperate with the radial drilling mechanism 100 to perform spline milling at different angles. The auxiliary mechanism 500 is installed at the top of the base mechanism 200. The auxiliary mechanism 500 is used for snap-fit ​​positioning of radial arms of different sizes.

[0033] The radial drilling mechanism 100 includes a radial arm frame 101, a spindle box 102, a rotating sleeve 103, and a column 104. The radial arm frame 101 is positioned above the base mechanism 200. The spindle box 102 slides on the radial arm frame 101. The radial arm frame 101 is connected to the spindle box 102 via a linear screw slide for adjusting the position of the spindle box 102 on the radial arm frame 101. The rotating sleeve 103 is driven by a drive source and rotates through the bottom of the spindle box 102. Driven by the motor drive source, the rotating sleeve 103 can rotate stably at the bottom of the spindle box 102. The milling mechanism 400 is slidably engaged with the bottom of the rotating sleeve 103. The column 104 is installed at one end of the base mechanism 200. The rocker arm 101 slides vertically on the outer wall of the column 104. The connection between the column 104 and the rocker arm 101 is the existing structure of the radial drilling machine, which can drive the spindle box 102 on the rocker arm 101 to move stably up and down.

[0034] In addition, the base mechanism 200 includes a base plate 201, a hydraulic telescopic rod 202, and a support plate 203. The base plate 201 is connected to the bottom of the column 104. The hydraulic telescopic rod 202 is fixed to the middle of the base plate 201 by a bracket. The support plate 203 slides and rises in the inner cavity of the base plate 201. The hydraulic telescopic rod 202 is fixedly connected to the bottom of the support plate 203. The auxiliary mechanism 500 is installed on the upper surface of the support plate 203. The hydraulic telescopic rod 202 is electrically connected to an external power supply through an external controller, which facilitates the movement of the support plate 203, making it easier to clean debris and other debris from the inner cavity of the base plate 201. Furthermore, the relative movement between the hydraulic telescopic rod 202 and the rocker arm 101 improves the processing efficiency of the steering rocker arm clamped on the auxiliary mechanism 500.

[0035] Furthermore, the connecting mechanism 300 includes a T-shaped rod 301, a limiting component 302, an adjusting component 303, and a rotating sleeve 304. The T-shaped rod 301 is inserted into the bottom of the spindle box 102, and the T-shaped structure of the T-shaped rod 301 prevents it from detaching from the bottom of the spindle box 102. The limiting component 302 is installed between the T-shaped rod 301 and the spindle box 102. The limiting component 302 is used to adjust and limit the height of the T-shaped rod 301, so that the length of the T-shaped rod 301 extending out of the bottom of the spindle box 102 can be adjusted, which facilitates the connection between the milling mechanism 400 and the rotating sleeve 103. Specifically, the limiting component 302 includes a rectangular groove 321, a limiting groove 322, a limiting block 323, a first compression spring 324, a first pull rope 325, a second pull rope 326, and a retaining ring 327. The rectangular groove 321 is located at the bottom of the spindle box 102, and the limiting groove 322 is located at the four corners of the rectangular groove 321. The limiting block 323 slides through the top two sides of the T-shaped rod 301, and the limiting block 323 is slidably connected to the inner cavity of the adjacent limiting groove 322. Through the sliding connection between the limiting block 323 and the adjacent limiting groove 322, the T-shaped rod 301 can be respectively engaged at the top and bottom of the inner cavity of the rectangular groove 321, facilitating the height adjustment of the T-shaped rod 301. The first compression spring 324 is fixed to one end of the limiting block 323, and the opposite ends of the two first compression springs 324 are fixed to the top two sides of the T-shaped rod 301. A pull rope 325 is fixedly connected to one end of one of the limiting blocks 323. The first pull rope 325 is slidably inserted into the top of the T-shaped rod 301. The second pull rope 326 is fixed to one end of another limiting block 323. Two first compression springs 324 are respectively sleeved on one end of the first pull rope 325 and the second pull rope 326. The other end of the second pull rope 326 is fixedly connected to the middle of the first pull rope 325. The second pull rope 326 is slidably inserted into the top of the T-shaped rod 301. A retaining ring 327 is fixed to the bottom of the first pull rope 325. By pulling the retaining ring 327, the first pull rope 325 and the second pull rope 326 can be pulled at the same time, so that the two first compression springs 324 at the top of the T-shaped rod 301 are compressed, so that the limiting block 323 can slide out of the inner cavity of the adjacent limiting groove 322, making the position adjustment of the T-shaped rod 301 convenient. Adjustment assembly 303 is installed at the bottom of T-shaped rod 301. Adjustment assembly 303 includes adjustment sleeve 331, U-shaped locking rod 332, and second compression spring 333. Adjustment sleeve 331 is rotatably inserted into the bottom of T-shaped rod 301. Rotating sleeve 304 is fixed to one side of adjustment assembly 303 and one end of adjustment sleeve 331. Rotating sleeve 304 is rotatably adjusted by locking bolts and milling mechanism 400. U-shaped locking rod 332 is inserted and connected to both the top and bottom of adjustment sleeve 331. The top of U-shaped locking rod 332 is slidably inserted and connected to the bottom of T-shaped rod 301. Next, the second compression spring 333 is sleeved and fixed to one end of the U-shaped clamp 332. One end of the second compression spring 333 is fixed to the bottom inner cavity of the adjusting sleeve 331. By pulling the U-shaped clamp 332, the second compression spring 333 is compressed, so that the top of the U-shaped clamp 332 can slide out of the bottom of the T-shaped rod 301. This allows the adjusting sleeve 331 to rotate and adjust at the bottom of the T-shaped rod 301, enabling the milling mechanism 400 to move in direction. This ensures that the milling mechanism 400 does not affect the connection between the bottom of the rotating shaft sleeve 103 and the drill rod, reducing the impact on the drilling hole of the steering rocker arm.

[0036] Furthermore, the milling mechanism 400 includes a positioning sleeve 401, a positioning component 402, and a milling component 403. One side of the positioning sleeve 401 is rotatably inserted into the inner cavity of the rotating sleeve 304, and the rotation angle of the adjusting sleeve 331 and the positioning sleeve 401 is adjusted by locking bolts so that when not in use, the positioning component 402 can be flipped to the top of the positioning sleeve 401 to prevent the positioning component 402 and the milling component 403 from affecting the drilling of the steering rocker arm. The positioning component 402 is located in the middle of the positioning sleeve 401 and is movably engaged with the rotating shaft sleeve 103. The milling component 403 is installed at the bottom of the positioning rod 422 and is used for milling the steering rocker arm. Through the engagement of the positioning component 402 with the rotating shaft sleeve 103, the rotating shaft sleeve 103 can drive the positioning component 402 to rotate and adjust the angle, so that the milling component 403 can mill different splines. Specifically, the positioning component 402 includes a positioning block 421, a positioning rod 422, a storage groove 423, and an inserting block 424. The positioning block 421 is rotatably inserted into the middle of the positioning sleeve 401 via a bearing. The positioning rod 422 is fixed to the bottom of the positioning block 421. Multiple storage grooves 423 are formed on the inner wall of the positioning block 421. The inserting block 424 is rotatably inserted into the inner cavity of the storage groove 423 via a pin. The inserting block 424 is movably engaged with the bottom mounting hole of the rotating sleeve 103. The top of the inserting block 424 has a flat structure that matches the bottom mounting hole of the rotating sleeve 103, and the inserting block 424 is far away from the storage groove 421. The side of 23 has a larger gravity. When the steering rocker arm is pressed against the bottom of the milling component 403, the oblique gravity of the insert block 424 can ensure that the insert block 424 is stuck on the rotating shaft sleeve 103, so that the rotating shaft sleeve 103 can drive the positioning block 421 to rotate through the insert block 424. The load of the positioning block 421 is supported by the positioning sleeve 401 and the connecting mechanism 300. The insert block 424 only serves as a connecting structure for the rotating shaft sleeve 103 to drive the positioning block 421 to rotate. Furthermore, by pulling down the positioning block 421, the installation and removal of the insert block 424 from the mounting hole on the rotating shaft sleeve 103 is convenient. More specifically, the milling assembly 403 includes a mounting plate 431, a rotating shaft 432, a milling cutter 433, a first gear 434, a second gear 435, and a motor with a shaft 436. The mounting plate 431 is slidably inserted into the bottom of the positioning rod 422 and is fixed to the outer wall of the positioning rod 422 by locking bolts. The locking bolts facilitate adjustment of the extension distance of the mounting plate 431. A counterweight ball is provided at the end of the mounting plate 431 away from the milling cutter 433 to ensure stable use of the milling cutter 433. The end of the rotating shaft 432 is rotatably inserted into one end of the mounting plate 431 via a bearing. The milling cutter 433 is fixedly inserted into the outer wall of the rotating shaft 432. The first gear 434 is fixed to one end of the rotating shaft 432. The second gear 435 is rotatably inserted into the inner cavity of the mounting plate 431. The second gear 435 meshes with the outer wall of the first gear 434. The output shaft of the shaft motor 436 is fixedly connected to the middle of the second gear 435. The shaft motor 436 is mounted on the outer wall of the mounting plate 431. The shaft motor 436 is electrically connected to an external power supply through an external controller. The output shaft of the shaft motor 436 is rotatably inserted into the middle of the mounting plate 431 through a bearing. This allows the second gear 435 to drive the milling cutter 433 to rotate stably through the first gear 434 and the rotating shaft 432, enabling the milling cutter 433 to perform spline milling or outer wall structure cutting operations on the steering rocker arm. This is suitable for multi-functional operation and processing of the steering rocker arm.

[0037] Meanwhile, the auxiliary mechanism 500 includes a first support base 501, a second support base 502, a clamping assembly 503, a first clamping head 504, and a second clamping head 505. The first support base 501 is fixed to one end of the support plate 203, and the second support base 502 is disposed at one end of the first support base 501. The second support base 502 is slidably connected to the top of the support plate 203. Multiple clamping assemblies 503 are respectively disposed at opposite ends of the first support base 501 and the second support base 502. Each clamping assembly 503 includes a movable groove 531, a bidirectional lead screw 532, and multiple sliders 533. The multiple movable grooves 531 are respectively opened at the bottom of the first support base 501 and the second support base 502. The two ends of the bidirectional lead screw 532 are rotatably connected to the inner wall of the movable groove 531 through bearings. Two adjacent sliders 533 rotate at the two ends of the bidirectional lead screw 532, and the two opposite first clamping heads 504 slide and insert into the inner wall of the first support base 501 on both sides. An arc-shaped groove structure is formed between the two first chucks 504, and a groove structure that mates with the end of the steering rocker arm is formed between the two second chucks 505. Two sliders 533 are fixedly inserted and connected to the middle of the two adjacent first chucks 504, and the two adjacent second chucks 505 are slidably inserted and connected to the two sides of the inner wall of the second support seat 502. Two other sliders 533 are fixedly inserted and connected to the middle of the two adjacent second chucks 505. By manually rotating one end of the bidirectional lead screw 532, the sliders 533 in the opposite state can perform clamping movement in the same direction. In conjunction with the groove structure on the first chucks 504 and the second chucks 505, they can support the two ends of the steering rocker arm. The structure of the first support seat 501 and the second support seat 502 does not affect the drilling hole at the end of the steering rocker arm, and the drilling debris can fall directly into the inner cavity of the first support seat 501 and the second support seat 502 without affecting subsequent processing.

[0038] Example 2, based on Example 1, further includes a fixing mechanism 600 and a slot 700. Multiple fixing mechanisms 600 are installed on both sides of the auxiliary mechanism 500, and multiple slots 700 are equidistantly opened on both sides of the base mechanism 200 and the support plate 203, respectively. The fixing mechanisms 600 and slots 700 facilitate the auxiliary mechanism 500 in engaging steering rocker arms of different lengths for automotive components, enabling them to rotate... The rocker arm can perform different machining operations. The fixing mechanism 600 includes a fixing frame 601, a fixing rod 602, a tension spring 603, a pull tube 604, a pull plate 605, and a clamping plate 606. The fixing frame 601 is fixed to the outer wall of the second bearing seat 502, the fixing rod 602 is fixed to the inner wall of the fixing frame 601, the tension spring 603 is sleeved on the outer wall of the fixing rod 602, and the pull tube 604 is slidably inserted through one end of the fixing frame 601. The pull tube 604 slidably passes through the outer wall of the fixing rod 602. The connection is made by inserting a pull plate 605, which is fixed to one end of the pull tube 604. The pull plate 605 slides through the outer wall of the fixing rod 602. The tension spring 603 is fixed between the pull plate 605 and the inner wall of the fixing frame 601. Multiple locking plates 606 are fixed to the bottom of the pull plate 605. The locking plates 606 are movably engaged with the inner cavity of the adjacent locking slot 700. By pulling the pull tube 604, the multiple locking plates 606 on the pull plate 605 can be pulled out of the inner cavity of the multiple locking slots 700 at the same time, so that the second bearing seat... The distance between 502 and the first bearing seat 501 is easy to adjust. When the pull tube 604 is released, the elastic pull of the tension spring 603 allows the locking plate 606 to engage with the locking groove 700 in the opposite state, further improving the stability of the position of the second bearing seat 502 on the bearing plate 203. At the same time, the first bearing seat 501 and the second bearing seat 502 can position and lock the steering rocker arms of different lengths, making the processing state of the steering rocker arms more stable.

[0039] Working principle: Based on the length of the processed steering rocker arm, pull the pull tubes 604 on both sides of the second bearing seat 502 to move the clamping plate 606 out of the inner cavity of the adjacent clamping slot 700. After adjusting the distance between the first bearing seat 501 and the second bearing seat 502, release the pull tubes 604. Through the elasticity of the tension spring 603, the clamping plate 606 can be inserted into the inner cavity of the clamping slot 700 in the relative state, so that the distance between the second bearing seat 502 and the first bearing seat 501 is fixed. According to the width of both ends of the steering rocker arm being processed, the bidirectional lead screw 532 on the first bearing seat 501 and the second bearing seat 502 are rotated respectively, so that the slider 533 can drive the two first chucks 504 and the two second chucks 505 to perform clamping action, so that one end of the steering rocker arm can be locked between the two first chucks 504 in the opposite state, and the other end can be locked between the two second chucks 505. By installing the drill rod at the bottom of the rotating shaft sleeve 103, the spindle box 102 is driven to rise and fall, so that the drill rod in the driving state drills holes at both ends of the steering rocker arm. After drilling is completed, the drill rod is removed from the rotating sleeve 103. By tightening the locking bolt on the rotating sleeve 304, the positioning sleeve 401 can be flipped. Pulling the adjusting component 303 causes the adjusting sleeve 331 and the T-shaped rod 301 to rotate and move the positioning sleeve 401 to the bottom of the rotating sleeve 103. Pulling the retaining ring 327 and adjusting the height of the T-shaped rod 301 allows the positioning block 421 to fit into the outer wall of the rotating sleeve 103. Due to the gravity of the insert block 424, the insert block 424 is inserted into the inner cavity of the mounting hole on the rotating sleeve 103, allowing the milling component 403 at the bottom of the positioning rod 422 to rotate at an angle. The drive shaft motor 436 causes its second gear 435 to drive the first gear 434 to rotate, enabling the milling cutter 433 to rotate. Through the lifting and moving of the rocker arm 101, the milling cutter 433 can perform spline milling on the steering rocker arm that is engaged on the first support 501 and the second support 502. At the same time, through the drive of the hydraulic telescopic rod 202, the support plate 203 can be lifted up, which can clean the top of the base plate 201.
