Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts testing, and in particular to a calibration device for automotive parts. Background Technology

[0002] In the large-scale automated production of automotive parts, achieving high-precision and high-efficiency online inspection is a key link in ensuring product quality. This is especially true for core components such as engines, chassis, and bodies, whose surfaces typically have multiple holes for precise positioning and assembly. The positional and coaxial tolerances of these holes must be strictly controlled; otherwise, it will directly affect the assembly accuracy, structural strength, and safety performance of the entire vehicle.

[0003] Existing detection devices typically include a set of vertically movable detection probes. The lifting and lowering motion is controlled by an independent drive source, such as a small cylinder, a linear motor, or a cam mechanism driven by an additional motor. When the sensor detects that a component on the conveyor belt has reached a predetermined station, the control system issues a command to activate the independent drive source, causing the detection head to descend and perform contact detection on the component. After the detection is completed, the probe rises and resets. This method attempts to embed the detection action into the production process to achieve a certain degree of online detection.

[0004] However, since the conveyor belt system and the inspection head lifting system are two independently controlled motion units, even with sophisticated sensors and a fast control system, absolute instantaneous synchronization is difficult to achieve during the start-up, acceleration, constant speed, deceleration, and stopping phases. While minor timing errors may be acceptable at low speeds, under the pursuit of high-efficiency, high-speed continuous production cycles, these minute timing errors caused by factors such as signal transmission, controller response, driver delay, and mechanical inertia accumulate and amplify. The timing of the inspection head's descent and the precise placement of the parts become unpredictably misaligned. This asynchrony can lead to several serious consequences: premature descent of the inspection head may result in impacts with still-moving parts or the conveyor belt itself; premature descent may result in targeting partially displaced parts or completely empty workstations, causing missed inspections. Both impacts and missed inspections severely affect the reliability of inspection, the stable operation efficiency of the production line, and may cause physical damage to equipment or high-value precision automotive parts. Therefore, to address these shortcomings, a calibration device for automotive parts is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a calibration device for automotive parts.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a calibration device for automotive parts, comprising:

[0007] The conveyor belt has multiple partitions on its outer surface for separating components;

[0008] The drive assembly includes: side plates symmetrically arranged on both sides of the conveyor belt, and a drive shaft rotatably arranged on the side plates; the conveyor belt is connected to the drive shaft in a transmission connection, and the drive assembly also includes a transmission linkage mechanism that converts the rotational motion of the drive shaft into reciprocating oscillation.

[0009] The support assembly includes: a column, a guide portion disposed on the column, and a sliding seat that moves up and down with the guide portion; the sliding seat is connected to the output end of a transmission linkage mechanism.

[0010] The detection assembly includes: a fixed plate connected to the sliding seat, a detection stage elastically connected to the fixed plate, and a pin disposed on the detection stage.

[0011] In a preferred embodiment of the present invention, the drive shaft includes an upper roll and a lower roll, and the conveyor belt passes between the upper roll and the lower roll and makes frictional contact.

[0012] In a preferred embodiment of the present invention, the transmission linkage mechanism includes: a crank shaft connected to one side of the upper roll, wherein the end of the crank shaft away from the upper roll is hinged to a connecting rod.

[0013] In a preferred embodiment of this utility model, the other end of the connecting rod is hinged to one end of the rocker arm, and the crank is connected to the sliding seat through the connecting rod and the rocker arm.

[0014] In a preferred embodiment of this utility model, the guide portion is a guide rail symmetrically arranged on the inner side of the column.

[0015] In a preferred embodiment of this utility model, the inside of the testing platform is provided with a plurality of reset springs, one end of which abuts against a pin.

[0016] In a preferred embodiment of this utility model, the sliding seat and the guide rail are connected by a slider and the guide rail.

[0017] In a preferred embodiment of this utility model, there are two columns, which are symmetrically arranged on both sides of the conveyor belt.

[0018] In a preferred embodiment of this utility model, the lower end or the entire outer periphery of the pin is covered with a rubber buffer layer.

[0019] In a preferred embodiment of this invention, the installation position of the pin corresponds to the position of the test hole on the component to be calibrated.

[0020] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0021] (1) This utility model provides a calibration device for automotive parts. The drive shaft drives the transmission linkage mechanism to synchronously drive the conveyor belt and the detection component to rise and fall, so that the detection action and the material conveying action originate from the same power and are forced to be synchronized. This avoids the timing error caused by the control delay and different response speed between multiple independent power sources. It eliminates the problem of collision between the detection head and the moving material or the problem of missed detection due to misalignment. Compared with the method of using an independent motor or cylinder to drive the detection head, this solution does not require a complicated synchronization control program and sensor feedback system. The structure is simple and reliable. This purely mechanical synchronization method ensures that even under extremely high production cycle, the start, process and reset times of the detection can maintain an absolutely accurate correspondence with the material conveying position.

[0022] (2) This utility model provides a calibration device for automotive parts. The rotational motion of the drive shaft is converted into the linear lifting motion of the detection component through the transmission linkage mechanism. The characteristics of this mechanism make the motion trajectory and speed curve of the detection head certain and predictable. The lifting process of the detection component is smooth and controllable. It can be relatively slow when approaching and leaving the workpiece to reduce impact, while it can pass quickly in the middle stroke section to improve efficiency. Compared with the problem of large speed impact and positioning accuracy relying on buffer elements caused by simple cylinder direct push, this solution realizes flexible and efficient detection action through the mechanical characteristics. This optimized motion characteristic reduces the impact wear on the parts and the detection head itself, extends the service life of the equipment, and ensures the repeatability of the detection positioning accuracy.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] like Figure 1 As shown, a calibration device for automotive parts includes:

[0031] The conveyor belt 1 has multiple partitions on its outer surface for separating parts, and a accommodating space for placing the parts to be calibrated is formed between two adjacent partitions.

[0032] It should be noted that the conveyor belt 1 is usually driven by a motor to rotate in a cycle. Its structure can adopt common forms such as belt, chain or synchronous belt. The conveyor belt 1 has an upper belt part and a lower belt part. During the conveying process, the parts to be calibrated are limited by the partition and move horizontally with the upper belt part so as to pass through the subsequent calibration stations in sequence.

[0033] like Figure 3 As shown, the drive assembly 2 includes: side plates 21 symmetrically arranged on both sides of the conveyor belt 1, and a drive shaft rotatably arranged on the side plates 21; the conveyor belt 1 is connected to the drive shaft in a transmission connection, and the drive assembly 2 also includes a transmission linkage mechanism that converts the rotational motion of the drive shaft into reciprocating oscillation.

[0034] like Figure 2 As shown, the support assembly 3 includes: a column 31, a guide portion disposed on the column 31, and a sliding seat 33 that moves up and down with the guide portion; the sliding seat 33 is connected to the output end of the transmission linkage mechanism.

[0035] like Figure 4 As shown, the detection assembly 4 includes: a fixed plate 41 connected to the sliding seat 33, a detection stage 42 elastically connected to the fixed plate 41, and a pin 44 disposed on the detection stage 42.

[0036] like Figure 1 and Figure 3 As shown, specifically, the drive shaft includes an upper roll 22 and a lower roll 23, which together constitute part of the drive shaft. The conveyor belt 1 passes through and rubs against the upper roll 22 and the lower roll 23. The lower surface of the conveyor belt 1 passes through and rubs against the upper roll 22 and the lower roll 23.

[0037] The conveyor belt 1 is clamped and frictionally driven by the upper roller 22 and the lower roller 23 to realize the conveying of parts. At the same time, the rotation of the drive shaft provides input power for the subsequent reciprocating motion.

[0038] Specifically, the transmission linkage mechanism includes: a crank 24 connected to one side of the upper roll 22, the crank 24 being fixedly connected to the end of the upper roll 22 and rotating synchronously via a key connection, the crank 24 making a circular motion as the upper roll 22 rotates, the end of the crank 24 away from the upper roll 22 being hinged to a connecting rod 25, and the crank 24 and the connecting rod 25 being connected by a hinge, so that the rotational motion is converted into the planar motion of the connecting rod 25;

[0039] The continuous rotation of the upper roller 22 drives the crank 24 to make a circular motion, which in turn pushes the connecting rod 25 to make a compound planar motion through the hinge point, converting the rotational motion of the drive shaft into the reciprocating motion of the connecting rod 25, providing a power source for the lifting and lowering of the detection component 4.

[0040] Specifically, the other end of the connecting rod 25 is hinged to one end of the rocker arm 26. The crank 24 is connected to the sliding seat 33 through the connecting rod 25 and the rocker arm 26. When the crank 24 drives the connecting rod 25 to move, the connecting rod 25 pushes the rocker arm 26 to swing around its fulcrum, thereby driving the sliding seat 33 to move up and down along the guide. The length of the rocker arm 26 can be changed to meet the needs of different lifting strokes.

[0041] like Figure 2 As shown, specifically, the guide part is a guide rail 32 symmetrically arranged inside the column 31. The guide rail 32 can be a linear guide rail, fixed in the vertical direction inside the column 31. The two guide rails 32 are located at the left and right ends of the inside of the column 31, respectively, to improve the guiding stability of the sliding seat 33.

[0042] Specifically, the sliding seat 33 and the guide rail 32 are connected by a slider and the guide rail. The sliding seat 33 can be equipped with a slider that cooperates with the guide rail 32. The slider can be equipped with balls or rollers to reduce friction and ensure that the sliding seat 33 does not deviate or jam during the lifting process.

[0043] Understandably, the guide rail 32 provides precise vertical guidance for the sliding seat 33, restricting its degree of freedom of movement and ensuring that the detection component 4 maintains alignment with the components during the lifting and lowering process.

[0044] Specifically, there are two columns 31, which are symmetrically arranged on both sides of the conveyor belt 1. The width between the two columns 31 can be adjusted according to the width of the conveyor belt 1 to ensure that the sliding seat 33 and the detection component 4 are located directly above the conveyor belt 1.

[0045] Furthermore, the symmetrically arranged columns 31 provide double-sided support for the sliding seat 33, ensuring that the detection component 4 is subjected to balanced forces during the lifting and lowering process, without lateral tilting.

[0046] like Figure 4 As shown, specifically, the inside of the testing table 42 is provided with several return springs 43. One end of the return spring 43 abuts against the pin 44. The return spring 43 can be set in the vertical direction, with its lower end abutting against the top or shoulder of the pin 44 and its upper end abutting against the top wall or fixed structure inside the testing table 42.

[0047] Furthermore, the pin 44 can slide up and down in the guide hole of the test stage 42, and the return spring 43 provides downward elastic pressure to the pin 44, so that it has a certain buffering and self-adaptive ability when contacting the parts.

[0048] Specifically, the lower end or the entire outer periphery of the pin 44 is covered with a rubber buffer layer, which reduces impact and wear when in contact with components.

[0049] Understandably, when the testing platform 42 descends, the pin 44 abuts against the hole to be tested on the component under the action of the return spring 43; if the hole is aligned, the pin 44 can be inserted smoothly; if there is a deviation, the rubber buffer layer and the return spring 43 can absorb part of the misalignment force to avoid damaging the component.

[0050] Specifically, the installation position of the pin 44 corresponds to the position of the test hole on the part to be calibrated. Multiple pins 44 can be provided on the test table 42, and their distribution position and diameter match the test hole on the part. The pins 44 can be replaced by disassembling the top of the test table 42 to facilitate the adaptation to parts of different specifications.

[0051] When this utility model is used, the conveyor belt 1, during operation, relies on the friction between its lower surface and the upper roller 22 and the lower roller 23 to drive the upper roller 22 and the lower roller 23 to rotate synchronously.

[0052] The crank 24 fixed to the shaft end of the upper roller 22 rotates accordingly, thereby converting the linear conveying motion of the conveyor belt 1 into the rotational motion of the crank 24.

[0053] The rotating crank 24 drives the rocker arm 26 to reciprocate through the connecting rod 25 hinged to it. The swing of the rocker arm 26 further pushes the sliding seat 33 connected to it, so that it makes a precise vertical lifting and lowering motion along the guide rail 32 fixed to the inside of the column 31.

[0054] Since the crank 24 is fixed to the shaft end of the upper roller 22, its rotation cycle is rigidly coupled with the movement rhythm of the conveyor belt 1 through the mechanical structure. Through precise mechanical design, the transmission linkage mechanism drives the sliding seat 33 to complete one lifting cycle every time the upper roller 22 rotates once, that is, when the conveyor belt 1 conveys the distance of one workstation.

[0055] This ensures that the descent of the sliding seat 33 and the detection component (4) on it is absolutely synchronized with the moment when the conveyor belt 1 accurately delivers each automotive part to the detection station directly below it;

[0056] When the component is in place, the sliding seat 33 drives the detection table 42 and the pin 44 at its bottom to descend. Under the action of the return spring 43, the pin 44 abuts against the surface of the component with appropriate pressure.

[0057] If the hole to be tested on the component is precisely aligned with the position of the pin 44, the pin 44, which is covered with a rubber buffer layer, will be smoothly inserted into the hole to complete the calibration.

[0058] If there is a slight positional deviation, the combination of the rubber buffer layer and the return spring 43 can provide flexible contact and cushioning, absorb the misalignment impact, and effectively avoid damage to precision parts.

[0059] After the test is completed, the sliding seat 33 rises and resets accurately under the drive of the transmission linkage mechanism;

[0060] Meanwhile, conveyor belt 1 continues to run, removing the parts that have been inspected and sending the next parts to be inspected into the inspection station, thereby realizing continuous, coordinated, and reliable automated cycle operation of inspection and conveying actions driven by a single power source.

[0061] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
