Description

Technical Field

[0001] The invention relates to the technical field of automobile chassis detection, in particular to an automatic conveying mechanism for automobile chassis detection. Background Art

[0002] The automobile chassis is one of the basic structures of the car, used to support the rest of the vehicle and carry key components such as the engine, transmission, wheels and suspension system. The design and construction of the chassis affects the safety, stability, driving comfort and handling of the car, so it is very important to test the quality of the automobile chassis.

[0003] During the manufacturing process of automobile chassis, most of the conveying and inspection are carried out through automated production lines. Through automatic conveying of automobile chassis inspection, the vehicle to be inspected is efficiently transported to the designated location. Then, the data of the automobile chassis is monitored through a scanning detection device. The automobile chassis is quality inspected based on the monitoring data, which greatly improves the efficiency and accuracy of the inspection.

[0004] When the automobile chassis is being inspected, it is conveyed by a linear conveyor belt. During the conveying process, due to the weight of the automobile chassis itself, the automobile chassis will shake and deviate under the action of inertia, which seriously affects the accuracy of the measurement data for multiple scanning and detection devices set at the bottom. When the automobile chassis is subjected to segmented and graded inspection, the automobile chassis needs to be conveyed and braked multiple times, which consumes a lot of time to stabilize the relative position of the automobile chassis and the detection device, reducing the efficiency of the automobile chassis inspection. At the same time, the deflection wear caused by inertia affects the service life of the conveying structure. Therefore, an automatic conveying mechanism for automobile chassis inspection is introduced. Summary of the invention

[0005] The object of the present invention is to provide an automatic conveying mechanism for detecting an automobile chassis to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] An automatic conveying mechanism for automobile chassis detection comprises a hoisting frame, an automobile chassis and a hoisting slide rail, an auxiliary mechanism is arranged on the top of the hoisting frame, the hoisting frame and the auxiliary mechanism are hoisted with the hoisting slide rail, a clamping mechanism is installed at the bottom of the hoisting frame, the clamping mechanism clamps the automobile chassis, and the automobile chassis is conveyed by traveling on the hoisting slide rail through the hoisting frame;

[0008] The auxiliary mechanism includes a card plate, a sliding rod is provided on one side of the card plate, a hydraulic cylinder is provided on one side of the card plate, a suspension rod is provided on the top of the sliding rod, a sliding groove is provided on the suspension rod, the top of the suspension rod is connected to a hanging beam, a top beam is installed on the top of the hanging beam, and a pulley is provided on the top of the top beam.

[0009] In one embodiment, the hanging frame includes a main frame, a side bar is provided on one side of the main frame, and the side bars are provided with four side bars, which are rectangularly distributed with respect to the top of the main frame, and rollers are provided on the top of the side bars, and the side bars are connected to the hanging rails through the rollers. When installing the hanging frame, the rollers on the top of the side bars are clamped with the hanging rails, and the rectangularly distributed side bars are stably connected to the hanging rails through the rollers, so as to stabilize the center of gravity of the main frame, improve the stability of the hanging frame moving on the hanging rails, avoid the problem of the center of gravity shifting and tipping of the hanging frame during transportation, and enhance the safety of the hanging frame.

[0010] In one embodiment, a support rod is provided on one side of the main frame, and two support rods are provided. The two support rods are symmetrically arranged on both sides of the main frame, and a card plate is installed in the middle of the two support rods. Two card plates are symmetrically arranged about the two ends of the support rod, and the card plate is movably connected to the support rod through a card slot, and the two ends of the hydraulic cylinder are respectively connected to the two card plates. The card plate is movably connected through the card slot on the support rod, and the inner wall of the card slot in the support rod is provided with a spring, and the spring resists the card plate to move toward the hydraulic cylinder, limiting the horizontal position of the card plate on the support rod, ensuring that the suspension rod is at the center position of the top of the support rod, and in the process of conveying the automobile chassis through the suspension frame, the card plate is used to slide along the slide groove on one side, and the card plate resists the spring buffer to offset the inertia generated by the automobile chassis during the acceleration and braking process, reducing the shaking of the automobile chassis during the transportation process, accelerating the braking stability of the automobile chassis, and facilitating rapid detection.

[0011] In one embodiment, the two suspension rods are provided with two suspension rods, which are symmetrically arranged with respect to the two ends of the hydraulic cylinder. The bottom of the suspension rod is movably connected with the card plate. The slide rod passes through the suspension rod through a slide groove, which is arranged in an arc shape. One end of the slide rod is movably connected with the inner wall of the slide groove through a roller. The slide grooves provided on the two suspension rods are symmetrically arranged with respect to the two ends of the hydraulic cylinder. By controlling the hydraulic cylinder to contract, the slide rod is driven to slide upward along the inner wall of the support rod slide groove, and the overall lifting frame at the bottom of the support rod is driven to rise, and the height of the automobile chassis at the bottom of the lifting frame is adjusted so that the relative distance between the automobile chassis and the detection device is consistent, thereby improving the accuracy of the monitoring device in detecting the automobile chassis.

[0012] In one embodiment, the hydraulic cylinder is connected to a pressure control system, the pressure control system includes a hydraulic pump body and a pressure relief valve, the pressure relief valve is connected to the hydraulic cylinder, and the hydraulic pump body is connected to the hydraulic cylinder through a conduit. The pressure inside the hydraulic cylinder is regulated by the hydraulic pump body, the length of the hydraulic cylinder is extended, and the height of the bottom hanging frame is regulated, so that the hanging frame is lowered to the lowest position on the hanging rod, and the length of the hydraulic cylinder is contracted, so that the hanging frame is raised to the highest position on the hanging rod. When the hanging frame moves on the hanging slide rail, the center of gravity of the hanging frame is pushed to shift under the action of inertia. The pressure inside the hydraulic cylinder is controlled by opening the pressure relief valve, so that the slide bar at one end of the hydraulic cylinder does not move, and the slide bar at the other end slides and deflects along the slide groove, reducing the wear of the top mechanical structure by inertial torsion and reducing strain. When the hanging frame is braked to stop conveying, the hydraulic cylinder is controlled to extend slowly to buffer the left and right shaking caused by braking. The inertial deflection is braked by the friction between the slide bar and the inner wall of the slide groove, thereby improving the safety of the device.

[0013] In one embodiment, the suspension beam is arranged parallel to the top beam, the bottom of the top beam is connected to the suspension beam through a vertical rod, the rod passes through the top beam and is connected to a pulley, and the top beam is connected to a lifting rail through the pulley. The connection between the roller and the pulley and the lifting rail improves the overall stability of the lifting frame.

[0014] The clamping mechanism includes a rotating rod, one end of which is connected to the main frame, a clamping rod is arranged at the bottom of the rotating rod, a counterweight block is arranged on one side of the rotating rod, a clamping rod is arranged at the bottom end of the clamping rod, and a clamping plate is arranged at one end of the clamping rod.

[0015] In one embodiment, one end of the rotating rod is connected to the main frame through a bearing, and one end of the rotating rod is connected to the output shaft of the driving motor. The clamping rod is formed into a deflectable structure through the driving motor and the rotating rod, and the counterweight is tilted with respect to one side of the rotating rod. By controlling the driving motor to adjust the rotation of the rotating rod, the angle between the rotating rod and the clamping rod is adjusted, so that the clamping rod can be opened quickly, which is convenient for the user to quickly adjust the spacing of the clamping rod, and improves the efficiency of the user in clamping the chassis of the car. Through the gravity of the counterweight, the clamping rod is assisted to deflect quickly toward the inside, reducing the working pressure of the driving motor and saving the operation time of the staff.

[0016] In one embodiment, the bottom end of the clamping rod is connected to one end of the clamping rod, and an L-shaped structure is formed between the clamping rod and the clamping rod. The L-shaped structure formed between the clamping rod and the clamping rod reduces the covering caused by clamping the automobile chassis, facilitates the rapid scanning of the automobile chassis surface data by the scanning and detection device, improves the scanning and detection efficiency, and at the same time changes the direction of the center of gravity of the automobile chassis acting on the clamping mechanism. The clamping mechanism cooperates with the hydraulic cylinder in the auxiliary mechanism to neutralize and stabilize the inertia caused by the center of gravity. During the transportation process, the hydraulic cylinder is extended to guide the deflection of the automobile chassis to ensure the stability of the automobile chassis on the clamping mechanism.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] By setting up auxiliary mechanisms and clamping mechanisms, the efficiency of automobile chassis conveying inspection is improved. When moving on the lifting slide rail, the center of gravity of the lifting frame is pushed to shift due to inertia, and the slide bar slides and deflects along the slide groove, reducing the wear of the top mechanical structure due to inertial torsion and reducing strain. When the lifting frame is braked to stop conveying, the hydraulic cylinder is controlled to extend slowly to buffer the left and right shaking caused by braking. Through the friction and extrusion between the slide bar and the inner wall of the slide groove, the shaking is converted into pressure on the hydraulic cylinder, and the inertial deflection is braked, thereby reducing the safety hazards caused by mechanical fatigue and improving the safety of the device.

[0034] A support rod 103 is provided on one side of the main frame 101. There are two support rods 103. The two support rods 103 are symmetrically arranged on both sides of the main frame 101. A clamping plate 201 is installed in the middle of the two support rods 103. Two clamping plates 201 are symmetrically arranged on both ends of the support rod 103. The clamping plate 201 is movably connected to the support rod 103 through a clamping groove, and the two ends of the hydraulic cylinder 203 are respectively connected to the two clamping plates 201. The card plate 201 is movably connected through the card slot on the support rod 103. The inner wall of the card slot in the support rod 103 is provided with a spring. The spring resists the card plate 201 from moving toward the hydraulic cylinder 203, limiting the horizontal position of the card plate 201 on the support rod 103, ensuring that the suspension rod 204 is at the center position of the top of the support rod 103. During the transportation of the automobile chassis 4 through the lifting frame 1, the card plate 201 is used to slide along the slide groove on one side of the support rod 103. The card plate 201 resists the spring buffer to offset the inertia generated by the automobile chassis 4 during the acceleration and braking process, reduce the shaking of the automobile chassis 4 during the transportation process, speed up the braking stability of the automobile chassis 4, and facilitate rapid detection.

The slide rod 202 passes through the suspension rod 204 through the slide groove 205. The slide groove 205 is arranged in an arc shape. One end of the slide rod 202 is movably connected to the inner wall of the slide groove 205 through a roller. The slide groove 205 provided on the two suspension rods 204 is symmetrically arranged at both ends of the hydraulic cylinder 203. By controlling the hydraulic cylinder 203 to contract, the slide rod 202 is driven to slide upward along the inner wall of the slide groove 205, driving the overall lifting frame 1 at the bottom of the support rod 103 to rise, adjusting the height of the automobile chassis 4 at the bottom of the suspension frame 1, so that the relative distance between the automobile chassis 4 and the detection device is consistent, thereby improving the accuracy of the monitoring device in detecting the automobile chassis 4.

[0036] The hydraulic cylinder 203 is connected to a pressure control system, which includes a hydraulic pump body and a pressure relief valve. The pressure relief valve is connected to the hydraulic cylinder 203, and the hydraulic pump body is connected to the hydraulic cylinder 203 through a conduit. The pressure inside the hydraulic cylinder 203 is regulated by the hydraulic pump body, the length of the hydraulic cylinder 203 is extended, and the height of the bottom lifting frame 1 is regulated, so that the lifting frame 1 drops to the lowest position on the suspension rod 204, and the length of the hydraulic cylinder 203 is contracted, so that the lifting frame 1 rises to the highest position on the suspension rod 204. When the lifting frame 1 moves on the lifting slide rail, the center of gravity of the lifting frame 1 is pushed to shift under the action of inertia, and the pressure inside the hydraulic cylinder 203 is controlled by opening the pressure relief valve, so that the slide bar 202 at one end of the hydraulic cylinder 203 is stationary, and the slide bar 202 at the other end slides and deflects along the slide groove 205, thereby reducing the wear of the top mechanical structure by inertial torsion and reducing strain. When the lifting frame 1 is braked to stop conveying, the hydraulic cylinder 203 is controlled to extend slowly to buffer the left and right shaking caused by braking, and the inertial deflection is braked by the friction between the slide bar 202 and the inner wall of the slide groove 205, thereby improving the safety of the device.

The connection between the roller and the pulley 208 and the hanging rail improves the overall stability of the hanging frame 1.

[0038] The clamping mechanism 3 includes a rotating rod 301, one end of which is connected to the main frame 101, a clamping rod 302 is arranged at the bottom of the rotating rod 301, a counterweight block 303 is arranged on one side of the rotating rod 301, a clamping rod 304 is arranged at the bottom end of the clamping rod 302, and a clamping plate 305 is arranged at one end of the clamping rod 304.

[0039] One end of the rotating rod 301 is connected to the main frame 101 through a bearing, and one end of the rotating rod 301 is connected to the output shaft of the driving motor. The clamping rod 302 forms a deflectable structure through the driving motor and the rotating rod 301, and the counterweight block 303 is tilted with respect to one side of the rotating rod 301. By controlling the driving motor to adjust the rotation of the rotating rod 301, the angle between the rotating rod 301 and the clamping rod 302 is adjusted, so that the clamping rod 302 is quickly opened, which is convenient for the user to quickly adjust the spacing of the clamping rod 302, and improves the efficiency of the user in clamping the automobile chassis 4. Through the gravity of the counterweight block 303, the clamping rod 302 is assisted to quickly deflect inward, reducing the working pressure of the driving motor and saving the operation time of the staff.

[0040] The bottom end of the clamping rod 302 is connected to one end of the clamping rod 304, and an L-shaped structure is formed between the clamping rod 302 and the clamping rod 304. The L-shaped structure formed between the clamping rod 302 and the clamping rod 304 reduces the covering caused by clamping the automobile chassis 4, facilitates the rapid scanning of the surface data of the automobile chassis 4 by the scanning and detection device, improves the scanning and detection efficiency, and at the same time changes the direction of the center of gravity of the automobile chassis 4 acting on the clamping mechanism 3. The clamping mechanism 3 cooperates with the hydraulic cylinder 203 in the auxiliary mechanism 2 to neutralize and stabilize the inertia caused by the center of gravity. During the transportation process, the hydraulic cylinder 203 is extended to guide the deflection of the automobile chassis 4 to ensure the stability of the automobile chassis 4 on the clamping mechanism 3.

[0041] Working principle of the present invention:

[0042] First, the automobile chassis 4 is placed on the clamping mechanism 3, and the rotation of the rotating rod 301 is adjusted by controlling the driving motor, and the angle between the rotating rod 301 and the clamping rod 302 is adjusted, so that the clamping rod 302 is quickly opened, which is convenient for the user to quickly adjust the spacing of the clamping rod 302, and improves the efficiency of the user in clamping the automobile chassis 4. Through the gravity of the counterweight block 303, the auxiliary clamping rod 302 is quickly deflected inward, so that the clamping rod 302 quickly clamps the automobile chassis 4, and reduces the working pressure of the driving motor;

[0043] The L-shaped structure formed between the clamping rod 302 and the clamping rod 304 reduces the covering caused by clamping the automobile chassis 4, facilitates the rapid scanning of the surface data of the automobile chassis 4 by the scanning and detection device, and improves the scanning and detection efficiency. At the same time, the center of gravity direction of the automobile chassis 4 acting on the clamping mechanism 3 is changed. The clamping mechanism 3 cooperates with the hydraulic cylinder 203 in the auxiliary mechanism 2 to neutralize and stabilize the inertia caused by the center of gravity. During the transportation process, the hydraulic cylinder 203 is extended to guide the deflection of the automobile chassis 4 to ensure the stability of the automobile chassis 4 on the clamping mechanism 3.

[0044] Then, the automobile chassis 4 is transported, and the rollers on the top of the side rods 102 are connected to the lifting rails. The rectangularly distributed side rods 102 are stably connected to the lifting rails through the rollers, which stabilizes the center of gravity of the main frame 101, improves the stability of the lifting frame 1 moving on the lifting rails, and avoids the problem of the lifting frame 1 shifting its center of gravity and tipping over during the transportation process. The connection between the rollers and the pulley 208 and the lifting rails improves the overall stability of the lifting frame 1;

[0045] During the transportation of the automobile chassis 4, the card plate 201 is movably connected through the card slot on the support rod 103. The inner wall of the card slot in the support rod 103 is provided with a spring. The spring resists the card plate 201 from moving toward the hydraulic cylinder 203, limiting the horizontal position of the card plate 201 on the support rod 103, ensuring that the suspension rod 204 is at the center position of the top of the support rod 103. During the transportation of the automobile chassis 4 by the lifting frame 1, the card plate 201 is used to slide along the slide groove on one side of the support rod 103. The card plate 201 resists the spring buffer to offset the inertia generated by the automobile chassis 4 during the acceleration and braking process, reduce the shaking of the automobile chassis 4 during the transportation process, speed up the braking stability of the automobile chassis 4, and facilitate rapid detection;

[0046] The slide grooves 205 provided on the two suspension rods 204 are symmetrically arranged about the two ends of the hydraulic cylinder 203. By controlling the hydraulic cylinder 203 to contract, the slide rod 202 is driven to slide upward along the inner wall of the slide groove 205, driving the overall suspension frame 1 at the bottom of the support rod 103 to rise, and adjusting the height of the automobile chassis 4 at the bottom of the suspension frame 1, so that the relative distance between the automobile chassis 4 and the detection device is consistent, thereby improving the accuracy of the monitoring device in detecting the automobile chassis 4;

[0047] The pressure inside the hydraulic cylinder 203 is regulated by the hydraulic pump body, the length of the hydraulic cylinder 203 is extended, and the height of the bottom lifting frame 1 is regulated, so that the lifting frame 1 drops to the lowest position on the suspension rod 204, and the length of the hydraulic cylinder 203 is contracted, so that the lifting frame 1 rises to the highest position on the suspension rod 204. When the lifting frame 1 moves on the lifting slide rail, the center of gravity of the lifting frame 1 is pushed to shift under the action of inertia, and the pressure inside the hydraulic cylinder 203 is controlled by opening the pressure relief valve, so that the slide bar 202 at one end of the hydraulic cylinder 203 is stationary, and the slide bar 202 at the other end slides and deflects along the slide groove 205, thereby reducing the wear of the top mechanical structure by inertial torsion and reducing strain. When the lifting frame 1 is braked to stop conveying, the hydraulic cylinder 203 is controlled to extend slowly to buffer the left and right shaking caused by braking, and the inertial deflection is braked by the friction between the slide bar 202 and the inner wall of the slide groove 205, thereby improving the safety of the device.
