Description

Technical Field

[0001] This utility model relates to the field of shock absorber processing technology, specifically to an automated processing device for the upper housing of a shock absorber. Background Technology

[0002] The shock absorber is a core component of a vehicle's suspension system. Its primary function is to dampen vibrations and impacts transmitted from uneven road surfaces to the vehicle body, ensuring smooth driving and ride comfort. The upper housing of the shock absorber, as an important part of this component, basically consists of a cylindrical body 42 (e.g., Figure 7 (As shown). The cylinder 42 has an inner ring plate 43 with a central through-hole inside, and an outer ring plate 44 on the outside of the cylinder 42. The outer ring plate 44 usually has three ear plates 45 arranged in a circumferential array, and each ear plate 45 has a bolt hole 46.

[0003] The manufacturing process of this housing involves several key processing and inspection steps: First, the inner top surface of the inner ring plate 43 needs to be milled to ensure its flatness and dimensional requirements. After milling, the distance (i.e., wall thickness) between the inner top surface 47 and the outer top surface 48 of the inner ring plate must be measured to determine whether the milling depth is qualified. Second, the bolt holes 46 on the ear plate 45 are initially in a blank state, and their processing usually requires two processes: rough drilling and fine drilling, to meet the requirements of hole diameter accuracy and surface quality. After fine drilling, the hole diameter and position also need to be inspected. In addition, markings need to be affixed to designated locations on the housing.

[0004] In current production, the five processes mentioned above—wall thickness inspection, marking, rough drilling of bolt holes, fine drilling of bolt holes, and drilling inspection—are generally carried out using separate workstations. Each workstation typically requires a dedicated operator to handle the corresponding process. This requires a significant investment of human resources, resulting in high labor costs, and the time-consuming transfer of workpieces between workstations leads to low production efficiency.

After the butt extends into place, it is located on the rotation path of the ear plate of the housing and can abut against one side of one of the ear plates.

[0009] A further improvement of this utility model is that the workstations of the thickness detection unit, marking unit, ear hole rough drilling unit, ear hole fine drilling unit, detection unit, and material removal and conveying unit are arranged at equal intervals along the length of the frame. The translation mechanism includes a base, and a slide block is slidably connected to the base along the length of the frame. A driving component is provided on one side of the slide block to drive its sliding. The five grippers are arranged at equal intervals along the length of the frame on the slide block, wherein the gripper located at the head end along the workpiece movement direction is a rotating gripper.

[0010] A further improvement of this utility model is that the coding unit includes a second support seat, the support surface of the second support seat is in contact with the outer ring plate of the housing, and it is provided with positioning protrusions that cooperate with the three ear plates. A laser coding device is provided above the second support seat.

[0011] A further improvement of this utility model is that the ear hole rough drilling unit includes a third support seat, the support surface of which contacts the outer ring plate of the shell, and a positioning protrusion thereon that cooperates with the outer side of the three ear plates. A first lifting pressure plate is provided above the third support seat. The first lifting pressure plate is provided with a through hole for avoiding the shell cylinder and a drill bit through hole corresponding to the position of the three ear holes. A lifting rough drilling mechanism is provided above the first lifting pressure plate. The lifting rough drilling mechanism includes a rough drilling bit corresponding to the position of the three drill bit through holes.

[0012] A further improvement of this utility model is that the ear hole precision drilling unit includes a fourth support seat, the support surface of which contacts the outer ring plate of the housing, and a positioning protrusion thereon that cooperates with the outer side of the three ear plates. A second lifting pressure plate is provided above the fourth support seat.

A lifting precision drilling mechanism is provided above the second lifting pressure plate. The lifting drilling mechanism includes precision drilling bits corresponding to the positions of the three drill bit through-holes.

[0013] A further improvement of this utility model is that the upper ends of the first and second lifting pressure plates are each provided with a protective tube that is coaxially arranged with the three drill bit openings thereon. The bearing surfaces of the third and fourth bearing seats are connected with chip removal pipes that are coaxially arranged with the protective tubes. The lower end of the chip removal pipe is connected to a collection container.

[0014] A further improvement of this utility model is that the detection unit includes a fifth support seat, the support surface of the fifth support seat is in contact with the outer ring plate of the housing, and it is provided with positioning protrusions that cooperate with the outer side of the three ear plates.

[0015] A further improvement of this utility model is that the platform is provided with an adjustment seat, and the upper end of the adjustment seat is slidably connected to an avoidance slide along the length of the frame.

Beneficial effects

[0016] This invention integrates thickness detection, marking, rough drilling, fine drilling, inspection, and rejection units, along with synchronous transfer units, to achieve continuous automated flow of workpieces across multiple workstations. This reduces manual intervention and workpiece turnaround time, improves production efficiency, and lowers labor costs.

[0017] The thickness detection unit of this invention positions the housing using positioning posts and positioning ring protrusions. Combined with an elastic distance sensor and a pressure head structure, the pressure head stably presses down on the outer ring plate, while the elastic distance sensor abuts against the inner top surface of the inner ring plate. This allows for the measurement of the inner ring plate wall thickness while simultaneously pressing the workpiece. Compared to manual measurement, this reduces errors and improves detection accuracy and efficiency.

[0018] The ear plate adjustment mechanism of this utility model uses a rotary motor to drive the positioning column to rotate the housing, and coordinates with the retractable butt head to position the ear plate angle, ensuring the positioning consistency of subsequent marking and drilling stations, and reducing the processing scrap rate caused by clamping errors.

[0019] The workstations of this invention are set at equal intervals and are arranged in a manner that complements the five grippers at equal intervals. A translation mechanism drives the five grippers to move between workstations, enabling rapid and continuous material handling. Furthermore, the first gripper is designed as a rotating gripper, which can actively rotate the housing during the material handling process to adapt to the different requirements of the thickness detection unit and subsequent units regarding the housing orientation.

[0020] The rough and fine drilling units of this utility model both adopt a bearing seat positioning protrusion and a lifting pressure plate clamping structure. The bearing surface of the bearing seat supports the outer ring plate, the positioning protrusion constrains the radial displacement of the ear plate, and the lifting pressure plate clamps the workpiece, effectively suppressing drilling vibration. The rough drill bit opens the hole, and the fine drill bit completes the final processing, improving the hole wall quality and dimensional accuracy. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1: Combination Figures 1-11 It is known that an automated processing device for the upper housing of a shock absorber includes: a frame 1, a feeding unit, a thickness detection unit 2, a marking unit 3, a rough drilling unit for the ear hole 4, a fine drilling unit for the ear hole 5, a detection unit 6, a material transfer unit 7, and a material rejection and conveying unit 8. The feeding unit is located at one end of the frame 1, the material feeding and conveying unit 8 is located at the other end of the frame 1, the thickness detection unit 2, the marking unit 3, the ear hole coarse drilling unit 4, the ear hole fine drilling unit 5 and the detection unit 6 are arranged sequentially on the table of the frame 1 along the length of the frame 1, and the material transfer unit 7 is arranged on one side of the table. The material transfer unit 7 includes a translation mechanism. Five grippers 9 are spaced apart along the length of the frame 1 on the moving end of the translation mechanism. The translation mechanism drives the five grippers 9 to move synchronously between the thickness detection unit 2, the marking unit 3, the ear hole rough drilling unit 4, the ear hole fine drilling unit 5, the detection unit 6, and the rejection conveying unit 8 to realize the sequential transfer of workpieces.

[0035] The thickness detection unit 2 includes a first support base 10, on which a positioning post 11 is provided to cooperate with the through-hole of the housing. The positioning post 11 has a positioning ring protrusion 12 on its outer periphery for contacting the outer top surface of the inner ring plate of the housing. A lifting measuring mechanism is provided above the first support base 10. The lifting measuring mechanism includes a lifting seat 13. At least two pressure heads 15 for pressing the outer ring plate of the housing are vertically arranged on the lifting seat 13 via a first connecting member 14. At least two elastic distance sensors 17 for abutting the inner top surface of the inner ring plate are vertically arranged on the lifting seat 13 via a second connecting member 16 (if a contact displacement sensor is used, its probe has an elastic reset function to ensure stable contact force). The first connecting member 14 has through-holes corresponding to the elastic distance sensors 17, so that the probes of the elastic distance sensors 17 can pass through and contact the housing below for detection. Preferably, both the first connecting member 14 and the second connecting member 16 are connecting plates. The lifting seat 13 is raised and lowered by a conventional lifting mechanism in the prior art, such as a cylinder or an electric lead screw. The diameter of the positioning post 11 is matched with the diameter of the opening in the housing, and is used to position the housing.

[0036] The thickness detection unit 2 also includes an ear plate adjustment mechanism. This mechanism includes a rotary motor 18 positioned below the bearing surface of the first support 10. A positioning post 11 is coaxially fixed to the output shaft of the rotary motor 18. A positioning adjustment rod 19 (preferably a pneumatic telescopic rod) is provided on one side of the first support 10. The positioning adjustment rod 19 includes a retractable abutment 20 that extends along the length of the frame. After extending into position, the abutment 20 is located on the rotation path of the ear plates of the housing and can abut against one side of one of the ear plates. The conveying shaft of the rotary motor 18 is vertically upward, and its output end is connected to the positioning post 11 via a connector. Preferably, the top of the positioning post 11 is tapered to facilitate the placement of the housing.

[0037] Preferably, the support 1 is equipped with a workpiece detection sensor (such as a photoelectric sensor or proximity switch). The workpiece detection sensor is located beside the positioning post 11 and is used to detect whether a shell workpiece is placed on the first support 10. The output signal of the workpiece detection sensor is connected to the control system of the tooling to automatically identify whether there is a shell on the support and prevent the detection action from being triggered accidentally under no-load conditions.

[0038] Preferably, the top plate of the support 1 is equipped with an ear plate detection sensor (such as a photoelectric sensor or proximity switch). Its detection direction is vertically upward, and the detection end is located below the rotation path of the ear plate on the housing. This sensor is used to detect whether an ear plate passes over it. The ear plate detection sensor is signal-connected to the positioning adjustment rod 19. The ear plate position is identified in real time. When an ear plate is detected passing over it, the positioning adjustment rod is triggered, ensuring that the stop 20 does not accidentally collide with the ear plate prematurely during its extension. This ensures that the housing is accurately stopped at the preset detection angle, reducing manual intervention.

[0039] The workstations of the thickness detection unit 2, marking unit 3, ear hole rough drilling unit 4, ear hole fine drilling unit 5, detection unit 6, and material removal and conveying unit 8 are arranged at equal intervals along the length of the frame 1. The translation mechanism includes a base 21, on which a slide block 22 is slidably connected along the length of the frame 1. A driving component (such as a cylinder) is provided on one side of the slide block 22 to drive its sliding. Five grippers 9 are arranged at equal intervals along the length of the frame 1 on the slide block 22. Among them, the gripper located at the first end along the workpiece movement direction is a rotating gripper 23. The first gripper is a rotating gripper 23, whose rotation axis is driven by a servo motor. It can rotate the workpiece 180° during the transfer process to meet the clamping direction requirements of the thickness detection unit (cylinder upward) and the subsequent unit (cylinder downward). Preferably, both clamping surfaces of the gripper 9 are provided with arc-shaped openings that match the outer diameter of the cylinder.

[0040] The marking unit 3 includes a second support base 24, the bearing surface of which contacts the outer ring plate of the housing, and it is provided with positioning protrusions 25 that mate with the three ear plates. A laser marking device 26 is provided above the second support base 24. The marking unit 3 quickly fixes the position of the ear plates through the positioning protrusions 25, and the laser marking device automatically marks at the preset position, avoiding manual marking misalignment and improving marking accuracy and speed. The positioning protrusions 25 can be three positioning blocks or positioning posts that match the outer circumference shape of the ear plates 45, used to radially constrain the ear plates 45 and ensure positioning consistency.

[0041] The ear hole rough drilling unit 4 includes a third support seat 27. The support surface of the third support seat 27 contacts the outer ring plate of the shell, and it is provided with positioning protrusions 25 that cooperate with the outer side of the three ear plates. A first lifting pressure plate 28 is provided above the third support seat 27. The first lifting pressure plate 28 is provided with a through hole for avoiding the shell cylinder and a drill bit through hole corresponding to the position of the three ear holes. A lifting rough drilling mechanism 30 is provided above the first lifting pressure plate 28. The lifting rough drilling mechanism 30 includes a rough drilling bit 31 corresponding to the position of the three drill bit through holes.

[0042] The ear hole precision drilling unit 5 includes a fourth support base 32. The support surface of the fourth support base 32 contacts the outer ring plate of the housing, and it is provided with positioning protrusions 25 that cooperate with the outer sides of the three ear plates. A second lifting pressure plate 33 is provided above the fourth support base 32. The second lifting pressure plate 33 is provided with a through-hole for avoiding the housing cylinder and a drill bit through-hole corresponding to the positions of the three rough drilling holes. A lifting precision drilling mechanism is provided above the second lifting pressure plate 33. The lifting precision drilling mechanism includes precision drilling bits 34 corresponding to the positions of the three drill bit through-holes. The lifting rough drilling mechanism 30 and the lifting precision drilling mechanism are conventional mechanisms in the prior art that can drive the drill bits to rise and fall. They may include a drive device such as a cylinder or servo cylinder, and a spindle motor or independent motor that drives the three drill bits to rotate.

[0043] The upper ends of the first lifting pressure plate 28 and the second lifting pressure plate 33 are each vertically provided with protective tubes 35, which are coaxially arranged with the three drill bit openings on them. The bearing surfaces of the third bearing seat 27 and the fourth bearing seat 32 are connected to chip removal pipes 36, which are coaxially arranged with the protective tubes 35. The lower end of the chip removal pipes 36 is connected to a collection container. The coaxial arrangement of the protective tubes and the chip removal pipes forms a chip removal channel, which can guide drill chips into the collection container (such as a chip collection box), preventing chip splashing from contaminating the equipment or interfering with subsequent testing, reducing the frequency of cleaning and maintenance, and ensuring a clean processing environment.

[0044] The detection unit 6 includes a fifth support base 37, the bearing surface of which contacts the outer ring plate of the housing, and it is provided with positioning protrusions 25 that cooperate with the outer sides of the three ear plates. An industrial camera 38 for capturing images of the three drilled holes is located above the fifth support base 37. Illumination devices such as a ring light source are used to ensure clear imaging. The detection unit captures images of the three drilled holes using the industrial camera, and the positioning protrusions ensure consistent workpiece posture, achieving efficient automated visual inspection of hole diameter and position, replacing manual sampling, and improving full inspection coverage and quality inspection efficiency. The industrial camera 38, combined with illumination devices such as a ring light source, acquires images and uses image processing technology to detect hole diameter and position, which is a conventional technique in the field of machine vision. The related hardware selection, light source arrangement, and image processing algorithms (such as edge detection and dimensional measurement) are all mature technologies in this field, and those skilled in the art can conventionally select and implement them according to actual inspection needs; these are not innovative aspects of this patent.

[0045] In this device, both the feeding unit (not shown in the figure) and the detection unit 6 employ mature automated devices from the prior art. The feeding unit is preferably a robotic arm, whose end effector grips the housing and precisely places it onto the positioning post 11 of the first support 10 of the thickness detection unit 2. The improvements of this invention do not involve the structure of the feeding unit itself.

[0046] This device also includes a control system (such as a PLC or industrial control computer), which is a conventional control system in the prior art. The control system is electrically connected to the feeding unit, thickness detection unit 2 (receiving signals from elastic distance sensor 17, workpiece detection sensor, and ear plate detection sensor, and controlling rotary motor 18, positioning adjustment rod 19, and lifting measurement mechanism), marking unit 3 (controlling laser marking device 26), ear hole rough drilling unit 4 (controlling the lifting of the first lifting pressure plate 28, the lifting rough drilling mechanism 30, and drilling), ear hole fine drilling unit 5 (controlling the lifting of the second lifting pressure plate 33, the lifting fine drilling mechanism, and drilling), detection unit 6 (triggering industrial camera 38 to take pictures), material transfer unit 7 (controlling the movement of translation mechanism, the opening and closing of each gripper 9, and the rotation of rotary gripper 23), and material removal and conveying unit 8 (controlling the start and stop of conveyor belt 49 and the action of material removal cylinder), to coordinate the orderly operation of each unit according to the preset program and realize the automated operation of the entire processing process.

[0047] It should be emphasized that the improvements of this utility model lie in the mechanical structure and layout. The control system itself and its basic programming logic are mature and conventional existing technologies and are not the innovative part of this patent. Its hardware selection, signal input / output interface configuration, and basic control logic (such as triggering the actuator after receiving sensor signals) are all well-known technologies in the field. For conventional technical details such as the internal circuit structure and programming methods of the control unit, those skilled in the art can directly adopt standard solutions according to actual needs; therefore, this specification will not elaborate further.

[0048] The rejecting conveyor unit includes a conveyor belt 49. At least one rejecting cylinder is provided on one side of the conveyor belt 49. A rejecting push plate 51 is provided on the telescopic end of the rejecting cylinder. A defective product collection box 50 corresponding to each rejecting push plate 51 is provided on the other side. The telescopic direction of the rejecting cylinder is consistent with the width direction of the conveyor belt 49. A good product collection box is provided at the end of the conveyor belt 49.

[0049] An adjustment seat 39 is provided on the table. A clearance slide 40 is slidably connected to the upper surface of the adjustment seat 39 along the length of the frame 1. One end of the clearance slide 40 is equipped with a sliding drive component (such as a cylinder) to drive its sliding. The lifting and measuring mechanism is fixedly connected to the clearance slide 40. When the gripper 9 of the transfer unit needs to enter the thickness detection station to grab or place a workpiece, the sliding drive component drives the clearance slide 40 to move the entire lifting and measuring mechanism laterally, making room for the gripper 9. After the gripper 9 retracts, the clearance slide 40 resets, and the lifting and measuring mechanism returns to its working position. The clearance slide 40 allows the thickness detection unit to move laterally, providing clearance space for the gripper of the transfer unit, avoiding interference between mechanisms, and ensuring smooth transfer of workpieces between the detection station and the transfer path.

[0050] The working principle of the automated processing device for the upper housing of a shock absorber provided by this utility model is as follows: After the workpiece is fed in by the feeding unit, the five grippers 9 of the transfer unit 7 move synchronously under the drive of the translation mechanism. The robotic arm of the feeding unit grabs the workpiece and sends it to the thickness detection unit 2. The housing is positioned by the positioning column 11 and the positioning ring protrusion 12. The lifting and measuring mechanism presses down the pressure head 15 to stabilize the workpiece. The elastic distance sensor 17 detects the wall thickness of the inner ring plate (the upper end face of the positioning ring protrusion 12 is the reference surface for wall thickness measurement, and the probe of the elastic distance sensor 17 elastically abuts against the inner top surface 47 of the inner ring plate to measure the distance between the inner top surface 47 and the outer top surface 48 of the inner ring plate). Qualified workpieces pass through the rotating grippers 2. The workpiece is transferred to the marking unit 3, where a laser marking machine 26 engraves a mark on the housing fixed by the positioning protrusion 25. It then enters the ear hole rough drilling unit 4, where the first lifting pressure plate 28 presses the housing, and the rough drill bit descends to open the ear plate hole. Next, it enters the ear hole fine drilling unit 5, where the fine drill bit performs sizing and finishing on the rough drilled hole. The drilled workpiece is then moved to the inspection unit 6, where an industrial camera 38 captures the dimensions and positions of the three holes. Finally, the workpiece is moved to the rejection conveying unit 8 via the material transfer unit 7. After one transfer by the material transfer unit 7, all workpieces at each station enter the next process. The feeding unit then places a new workpiece into the vacated thickness inspection station. The entire device operates in this cycle, achieving continuous automated processing, inspection, and sorting of the shock absorber upper housing 41.
