Abstract
Description
Technical Field
[0001] This application relates to the field of adjustable arm processing equipment technology, and in particular to an automatic drilling device for adjustable arms. Background Technology
[0002] Automotive adjustable booms, also known as automatic brake clearance adjusters or automatic adjusters, are a mature technology widely used abroad. In recent years, truck, bus, and trailer manufacturers in Europe and America have adopted them as standard equipment for their vehicles. The adjustable boom consists of a boom body, mounting pins, and adjusting nuts. The front of the boom body has mounting holes for the turbine, and the rear of the boom body has a positioning pin for connecting the shaft.
[0003] A search revealed that patent document CN212145281U discloses an automatic drilling and tapping device for automotive brake adjusting arms, which addresses the shortcomings of existing technologies such as high manufacturing costs and low work efficiency. The device includes a support leg, a drilling device, a tapping device, an unloading slide, and a loading slide. A worktable is fixed to the top of the support leg using countersunk bolts. When the turntable moves the fixture plate to the loading position, the fixed rod rotates the rotating rod, causing the stop block to enter the through hole. The workpiece automatically slides down the slide onto the fixture plate, achieving automatic loading. Through the design of pressure sensors and electric pressure rods, after loading, the workpiece touches the pressure sensor, causing the electric pressure rod to slide, achieving automatic clamping and fixing of the workpiece. When the fixture plate moves to the unloading position, the infrared sensing system activates, causing the pushing cylinder to automatically push the workpiece to the unloading slide, achieving automatic unloading. This device boasts a high degree of automation and significantly improved work efficiency.
[0004] In practical use, it was found that existing equipment is not convenient for firmly clamping and shock-absorbing the adjusting arm when drilling, which can easily lead to instability of the adjusting arm during drilling and thus affect the processing quality of the adjusting arm. Therefore, we proposed an automatic drilling device for adjusting arms to solve the above problems. Utility Model Content

V-grooves are opened on the adjacent side of the two clamping seats 104. The bottom of the clamping seat 104 is fixedly connected to the top of the corresponding screw seat 103.
[0039] Specifically, the lifting mechanism includes a hydraulic cylinder 201 and a lifting seat 202. The hydraulic cylinder 201 is fixedly installed on the top of the top plate 2. The bottom end of the output shaft of the hydraulic cylinder 201 passes through the bottom of the top plate 2. The lifting seat 202 is fixedly installed on the bottom end of the output shaft of the hydraulic cylinder 201. The rear side of the lifting seat 202 is slidably connected to the front side of the support plate 7. The bottom of the lifting seat 202 is fixedly connected to the top of the mounting base 3. A gear mechanism is provided between the lifting seat 202 and the bidirectional screw 102.
[0040] Specifically, the gear mechanism includes a rack plate 501 and a gear 502. The rack plate 501 is fixedly installed at the bottom of the lifting seat 202. The rack plate 501 is located on the left side of the mounting seat 3. The rack plate 501 is slidably connected to the inner walls on both sides of the plate hole 5. The gear 502 is fixedly sleeved on the bidirectional screw 102. The gear 502 is located on the left side of the corresponding screw seat 103. The rack plate 501 and the gear 502 mesh with each other.
[0041] Specifically, the drilling mechanism includes a drill bit 301 and a drill bit 302. The drill bit 301 is fixedly installed at the bottom of the mounting base 3, and the drill bit 302 is provided at the bottom of the drill bit 301.
[0042] Specifically, the damping mechanism includes a damper 401 and a spring 402. The damper 401 is fixedly installed at the bottom of the mounting base 3. The damper 401 is located outside the drill 301. The bottom end of the damper 401 is fixedly connected to the top of the pressure plate 4. The spring 402 is sleeved on the damper 401. The two ends of the spring 402 are fixedly connected to the bottom of the mounting base 3 and the top of the pressure plate 4, respectively.
[0043] Specifically, the pressure plate 4 has through holes, and the drill bit 302 is adapted to the through holes.
[0044] Specifically, the same fixing rod is fixedly installed on the inner walls of both sides of the bottom box 1. The fixing rod is located below the bidirectional screw 102, and the screw seat 103 is slidably sleeved on the fixing rod.
[0045] Specifically, a controller is installed on the front side of the bottom box 1, located above the box door, and is electrically connected to the hydraulic cylinder 201.
[0046] In this application, during operation, the operator first precisely mounts the adjusting arm onto the positioning seat 101 on top of the base box 1. The positioning seat 101 provides a precise initial positioning reference for the adjusting arm, ensuring the accuracy of the subsequent drilling position. By activating the hydraulic cylinder 201, its output shaft extends downward, pushing the lifting seat 202 to perform a linear descent. As the lifting seat 202 descends, the rack plate 501 fixed at its bottom moves downward synchronously. The rack plate 501 meshes with the gear 502 fixedly mounted on the bidirectional screw 102, which can convert the linear movement of the lifting seat 202 into rotation. The rotational motion of the bidirectional screw 102 is transformed into that of the two screw seats 103, which can drive the two screw seats 103 to make linear movements in opposite directions or away from each other. At this time, the clamping seats 104, which are fixedly connected to the top of the screw seats 103, move synchronously. The V-shaped grooves opened on the adjacent side of the two clamping seats 104 can adapt to the shape of the adjustment arm. When the two clamping seats 104 move towards each other, the wedge action of the V-shaped grooves can be used to firmly clamp the adjustment arm on the positioning seat 101, which can effectively prevent the adjustment arm from shifting or shaking during the drilling process and ensure the drilling position accuracy.
[0047] Simultaneously, the descent of the lifting seat 202 causes the mounting seat 3 and the drilling mechanism, shock absorption mechanism, and pressure plate 4 at the bottom of the mounting seat 3 to descend synchronously. This allows the pressure plate 4 to squeeze and limit the top of the adjusting arm. The drill 301 drives the drill bit 302 to rotate at high speed. During the rotation, the drill bit 302 gradually approaches and cuts into the adjusting arm, achieving the purpose of drilling the adjusting arm. During the drilling process, the shock absorption mechanism composed of the damper 401 and the spring 402 between the mounting seat 3 and the pressure plate 4 plays an important role. The damper 401 consumes vibration energy through its internal damping medium, while the spring 402 acts as a buffer and provides elastic support. The two work together to effectively reduce the vibration and impact generated during the drilling process, improve the service life and drilling accuracy of the drill bit 302, and reduce noise during processing. The through hole on the pressure plate 4 is adapted to the drill bit 302, providing precise guidance for the drill bit 302 and ensuring that the drill bit 302 can accurately drill the adjusting arm.
