Description

Technical Field

[0001] This application relates to the field of drilling machine technology, and in particular to a hydraulic automatic feed drilling machine for adjusting arm machining. Background Technology

[0002] In the manufacturing of automotive braking systems, the adjusting arm, as a key component, directly affects the stability and safety of braking performance due to the quality of its hole machining. The core function of the adjusting arm is to automatically or manually adjust the clearance between the brake shoes and the brake drum, ensuring the safety and reliability of the braking system. By maintaining a constant brake clearance, it optimizes braking torque, thereby preventing brake failure, extending component life, and improving driving safety. Drilling the adjusting arm requires an automatic feed drilling machine.

[0003] In the existing technology, traditional hydraulic automatic feed drilling machines for adjusting arms mostly use single-axis drilling machines with only one drill bit, which can only process one hole at a time. Since multiple holes need to be processed on the adjusting arm, multiple clamping and repositioning are required, resulting in long processing time and low work efficiency for a single piece.

[0004] Therefore, we propose an adjustable arm machining hydraulic automatic feed drilling machine to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a hydraulic automatic feed drilling machine for machining adjusting arms, which can perform multi-hole drilling operations on adjusting arms simultaneously, and can process multiple holes on the adjusting arm at the same time, thereby significantly shortening the processing time of a single piece and improving work efficiency.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an automatic hydraulic feed drilling machine for adjusting arm machining, comprising a machine base, an adjusting arm placement seat and a drilling machine body fixedly installed on the top of the machine base, a hydraulic cylinder fixedly embedded in the bottom of the drilling machine body, a hydraulic telescopic rod slidably installed inside the hydraulic cylinder, the bottom end of the hydraulic telescopic rod being located outside the hydraulic cylinder, and a feed drilling mechanism being provided at the bottom end of the hydraulic telescopic rod, the feed drilling mechanism comprising a motor, a fixed box, multiple vertical shafts, multiple drill bits, a gear transmission assembly and multiple sets of belt transmission assemblies, the motor being fixedly installed at the bottom end of the hydraulic telescopic rod, the fixed box being fixedly installed at the bottom of the motor, the output shaft end of the motor extending into the fixed box, multiple vertical shafts being rotatably installed at the bottom of the fixed box, and the top ends of multiple vertical shafts extending into the fixed box, multiple drill bits being fixedly installed at the bottom ends of the corresponding vertical shafts, and the gear transmission assembly and multiple sets of belt transmission assemblies being located inside the fixed box.

[0007] By adopting the above technical solution, the hydraulic telescopic rod is used to drive the feed drilling mechanism to move vertically, eliminating the need for manual intervention in the feed drilling process.

[0008] A further configuration of this application is as follows: the gear transmission assembly includes a main gear and a secondary gear. The main gear is fixedly installed on the output shaft end of the motor, and the secondary gear is fixedly installed on the top end of one of the vertical shafts. The main gear and the secondary gear mesh with each other. The belt transmission assembly includes two pulleys and a belt. The two pulleys are respectively fixedly sleeved on two adjacent vertical shafts, and the belt is tensioned and sleeved on the two pulleys.

[0009] By adopting the above technical solution, the rotation of the vertical shaft connected to the secondary gear can be controlled by the meshing transmission action of the main gear and the secondary gear. The rotation of two adjacent vertical shafts can be controlled by the transmission action of two pulleys and belts. Under the joint action of multiple belt drive components, multiple vertical shafts can be rotated synchronously, multiple drill bits can be rotated synchronously, and multiple holes can be drilled simultaneously, thus improving work efficiency.

[0010] A further feature of this application is that: multiple mounting holes are provided on the bottom inner wall of the machine mounting box, and bearings are fixedly sleeved on multiple vertical shafts, with the outer rings of the multiple bearings respectively fixedly connected to the inner wall of the corresponding mounting hole.

[0011] By adopting the above technical solution, the smooth rotation of the vertical axis is ensured.

The oil pressure inside the hydraulic cylinder can push the hydraulic telescopic rod to descend and extend vertically. Through the synergistic action of the return pump, return pipe one and return pipe two, the hydraulic oil in the hydraulic cylinder can be delivered back to the hydraulic oil tank, thereby reducing the pressure inside the hydraulic cylinder and controlling the hydraulic telescopic rod to rise and reset vertically.

[0016] A further feature of this application is that a flow regulating valve is fixedly installed on both the oil drain pipe and the oil return pipe.

[0017] By adopting the above technical solution, the design of two flow regulating valves is used to control the flow rate of hydraulic oil in the drain pipe and return pipe respectively, thereby adjusting the lifting speed of the hydraulic telescopic rod.

[0018] A further feature of this application is that two vertically arranged stroke rods are fixedly installed on the top of the machine tool, and guide arms are fixedly installed on both the left and right sides of the hydraulic telescopic rod, with the two guide arms slidingly sleeved on the corresponding stroke rods.

[0024] A further feature of this application is that a protective cover is fixedly fitted around the top outer periphery of the machine tool.

[0025] By adopting the above technical solution, the protective cover can effectively block iron filings that fly out during the drilling process.

[0026] This application includes at least one of the following beneficial technical effects:

[0027] 1. This application utilizes a hydraulic telescopic rod to drive the vertical lifting and lowering of the feed drilling mechanism, which enables simultaneous drilling of multiple holes in the adjusting arm. This allows for the simultaneous processing of multiple holes in the adjusting arm, significantly shortening the processing time per piece.

[0035] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides an automatic hydraulic feed drilling machine for adjusting arm machining, including a machine base 1. An adjusting arm placement seat 2 and a drilling machine body 3 are fixedly mounted on the top of the machine base 1. A hydraulic cylinder 4 is fixedly embedded in the bottom of the drilling machine body 3. A hydraulic telescopic rod 5 is slidably mounted inside the hydraulic cylinder 4. The bottom end of the hydraulic telescopic rod 5 is located outside the hydraulic cylinder 4. A feed drilling mechanism 6 is provided at the bottom end of the hydraulic telescopic rod 5. The hydraulic telescopic rod 5 is used to drive the feed drilling mechanism 6 to move vertically, thus eliminating the need for manual intervention in the feed drilling process. The feed drilling mechanism 6 includes a motor 61, a fixed... The system comprises a fixed housing 62, multiple vertical shafts 63, multiple drill bits 64, a gear transmission assembly, and multiple sets of belt transmission assemblies. A motor 61 is fixedly mounted at the bottom end of the hydraulic telescopic rod 5. The fixed housing 62 is fixedly mounted at the bottom of the motor 61, with the output shaft of the motor 61 extending into the fixed housing 62. Multiple vertical shafts 63 are rotatably mounted at the bottom of the fixed housing 62, with their top ends extending into the fixed housing 62. Multiple drill bits 64 are respectively fixedly mounted at the bottom ends of their corresponding vertical shafts 63. The gear transmission assembly and multiple sets of belt transmission assemblies are all located within the fixed housing 62. The gear transmission assembly includes a main gear 65 and a secondary gear 66. The main gear 65 is fixedly mounted on the output shaft end of the motor 61, and the secondary gear 66 is fixedly mounted on the top end of one of the vertical shafts 63. The main gear 65 and the secondary gear 66 mesh with each other. The belt transmission assembly includes two pulleys 67 and a belt 68. The two pulleys 67 are respectively fixedly sleeved on two adjacent vertical shafts 63, and the belt 68 is tensioned and sleeved on the two pulleys 67. The motor 61 is used to control the rotation of the main gear 65. Utilizing the meshing transmission action of the main gear 65 and the secondary gear 66, the transmission can be controlled... The vertical shaft 63 connected to the auxiliary gear 66 rotates. Utilizing the transmission action of two pulleys 67 and belt 68, two adjacent vertical shafts 63 can be controlled to rotate simultaneously. With the combined action of multiple sets of belt drive components, multiple vertical shafts 63 can rotate synchronously, thereby enabling multiple drill bits 64 to rotate synchronously. This allows for simultaneous drilling of multiple holes. Compared to traditional single-axis drilling machines, it can process multiple holes in the adjusting arm simultaneously, significantly shortening the processing time for a single piece. It is especially suitable for batch production of adjusting arms, significantly increasing output per unit time and improving work efficiency.

[0037] In this embodiment, multiple mounting holes are provided on the bottom inner wall of the fixed box 62, and bearings are fixedly sleeved on multiple vertical shafts 63. The outer rings of multiple bearings are fixedly connected to the inner walls of the corresponding mounting holes to ensure smooth rotation of the vertical shafts 63.

[0038] In this embodiment, the front side of the fixing box 62 is an open structure, and a cover plate 69 is fixedly installed on the outer wall of the front side of the fixing box 62 by screws, so as to facilitate the inspection, maintenance and upkeep of the inside of the fixing box 62.

[0039] In this embodiment, a hydraulic oil tank 7 is fixedly installed on the left outer wall of the machine tool 1. The hydraulic oil tank 7 contains hydraulic oil. An oil delivery pump 8 and a return pump 9 are fixedly installed on the left outer wall of the hydraulic oil tank 7. An oil delivery pump 8 and a return pump 9 are fixedly installed on the suction end of the oil delivery pump 8. An oil suction pipe 10 is fixedly connected to the suction end of the oil delivery pump 8, and one end of the oil suction pipe 10 extends into the hydraulic oil tank 7. An oil discharge pipe 11 is fixedly connected to the discharge end of the oil delivery pump 8, and one end of the oil discharge pipe 11 is fixedly connected to the hydraulic cylinder 4. An oil return pipe 12 is fixedly connected to the suction end of the return pump 9, and one end of the oil return pipe 12 is fixedly connected to the hydraulic cylinder 4. A return oil pipe 2 13 is fixedly connected, with one end of the return oil pipe 2 13 fixedly connected to the hydraulic oil tank 7. By utilizing the coordinated action of the oil pump 8, the oil suction pipe 10, and the oil discharge pipe 11, hydraulic oil can be delivered to the hydraulic cylinder 4. Then, by utilizing the oil pressure inside the hydraulic cylinder 4, the hydraulic telescopic rod 5 can be pushed to vertically descend and extend. By utilizing the coordinated action of the return oil pump 9, the return oil pipe 1 12, and the return oil pipe 2 13, the hydraulic oil inside the hydraulic cylinder 4 can be delivered back to the hydraulic oil tank 7, thereby reducing the pressure inside the hydraulic cylinder 4 and controlling the hydraulic telescopic rod 5 to vertically rise and reset.

[0040] In this embodiment, flow regulating valves 14 are fixedly installed on both the drain pipe 11 and the return pipe 12 to control the flow rate of hydraulic oil in the drain pipe 11 and the return pipe 12 respectively, thereby adjusting the lifting speed of the hydraulic telescopic rod 5.

[0041] In this embodiment, two vertically arranged stroke rods 15 are fixedly installed on the top of the machine base 1. Guide arms 16 are fixedly installed on both the left and right sides of the hydraulic telescopic rod 5. The two guide arms 16 are slidably sleeved on the corresponding stroke rods 15 to ensure that the hydraulic telescopic rod 5 maintains stable lifting and lowering. Guide arms 27 are fixedly installed on both the left and right sides of the fixed box 62. The two guide arms 27 are slidably sleeved on the corresponding stroke rods 15 to ensure that the feed drilling mechanism 6 maintains stable lifting and lowering.

[0042] In this embodiment, two L-shaped frames 18 are fixedly installed on the top of the machine base 1. The two L-shaped frames 18 are symmetrically distributed on the left and right sides of the adjusting arm placement seat 2. Electric telescopic rods 19 are fixedly installed on the inner top walls of the two L-shaped frames 18. Pressure plates 20 are fixedly installed on the output shaft ends of the two electric telescopic rods 19. The pressure plates 20 can be vertically raised and lowered by the electric telescopic rods 19, thereby pressing and fixing the adjusting arm on the adjusting arm placement seat 2 to prevent the adjusting arm placement seat 2 from shifting during the drilling process.

[0043] In this embodiment, a protective cover 21 is fixedly fitted on the outer periphery of the top of the machine tool 1. The protective cover 21 can effectively block the iron filings that fly during the drilling process, so as to avoid injury to the operator and aggravate the surrounding dirt and mess.

[0044] With the above structure, when using the hydraulic automatic feed drilling machine for adjusting arm processing provided in this application, the adjusting arm to be processed is first placed on the adjusting arm placement seat 2, and the two electric telescopic rods 19 are controlled to extend and run, respectively driving the pressure plate 20 at the bottom of them to move vertically downward. With the coordinated operation of the two pressure plates 20, the adjusting arm can be pressed tightly on the adjusting arm placement seat 2, avoiding displacement of the adjusting arm due to vibration or cutting force during the drilling process, and providing a basic guarantee for the subsequent drilling accuracy.

[0045] After the adjusting arm is pressed and fixed, the control motor 61 is run. The output shaft of the motor 61 drives the main gear 65 to rotate. By using the meshing transmission action of the main gear 65 and the auxiliary gear 66, the rotation of the vertical shaft 63 connected to the auxiliary gear 66 can be controlled. By using the transmission action of the two pulleys 67 and the belt 68, the rotation of two adjacent vertical shafts 63 can be controlled simultaneously. Then, under the joint action of multiple sets of belt drive components, multiple vertical shafts 63 can be rotated synchronously, thereby realizing the synchronous rotation of multiple drill bits 64.

[0046] Next, the oil pump 8 is started and hydraulic oil is drawn from the hydraulic oil tank 7 through the suction pipe 10 and delivered to the hydraulic cylinder 4 through the discharge pipe 11. As the oil pressure in the hydraulic cylinder 4 increases, the hydraulic telescopic rod 5 is pushed to extend vertically downward, which drives the bottom feed drilling mechanism 6 to move down as a whole. With multiple drill bits 64 rotating synchronously, they can gradually contact the adjusting arm and start cutting and drilling, thus enabling multi-hole drilling operations. Multiple holes of the adjusting arm can be processed at the same time, which greatly shortens the processing time of a single piece and improves work efficiency.

[0047] Once the drilling reaches the preset depth, the motor 61 is stopped, and the return oil pump 9 is started. The hydraulic oil in the hydraulic cylinder 4 is drawn back to the hydraulic oil tank 7 through the return oil pipe 12 and the return oil pipe 23. After the oil pressure in the hydraulic cylinder 4 decreases, the hydraulic telescopic rod retracts upward under the action of the return spring inside (the return spring is a prior art in this field), driving the feed drilling mechanism 6 to return to its original position. Then, the two electric telescopic rods 19 are controlled to retract and return to their original positions, which controls the two pressure plates 20 to rise and return to their original positions. The drilled adjusting arm can then be removed. Following the above operating steps, drilling can continue for the next adjusting arm.
