Abstract
Description
TECHNICAL BACKGROUND
[0001] The present patent application relates to the field of gear machining, in particular to the subject of transport and quality detection, and discloses in particular an integrated device for feeding and quality detection of bevel gears as well as a method for their use. CURRENT STATE OF THE TECHNOLOGY
[0002] A wide variety of planetary bevel gears are used in differential systems. To ensure efficient assembly, many customers require all products to be inspected. This necessitates determining the diameter of the central bore of a planetary bevel gear. However, current methods only allow for manual measurement of this diameter, using a shaft or measuring rod. Due to the extremely large number of bevel gears, determining the diameter of the planetary bevel gear's central bore has become the most time-consuming task for quality assurance. Therefore, an automated detection device is urgently needed.
[0003] CN 1 09 719 045 A discloses an automatic sorting device for inspecting the surfaces of tubular parts on a conveyor belt. The automatic sorting device comprises: a workbench, a drive support base, an angle indexing drive, a turntable, and an inspection device. The drive support base is mounted on the workbench. The angle indexing drive is attached to the workbench, with its output end passing through the drive support base and being vertically rotatable from the turntable. The inspection device is mounted on the drive support base and positioned above the turntable. The turntable is equipped with several movable bottleneck mounting rods. The bottleneck mounting rods are used to secure tubular parts and, as the turntable rotates, pass through the inspection stations of the device in succession.The inspection device is used to check the tubular parts passing through one after the other. DESCRIPTION
[0004] In view of the disadvantages of the previous state of the art, the present invention provides an integrated device for the transport and quality control of bevel gears and a method for their use, wherein a central bore of a bevel gear is checked as part of a transport process and the forwarding of the bevel gear takes place according to certain criteria.
[0005] The present invention is realized by the following technical solution. An integrated device for conveying bevel gears and for quality inspection comprises a rotary housing and a rotary drive for rotating the rotary housing about a horizontal axis. Eight detection housings are fixed to an outer ring of the rotary housing and evenly distributed around its circumference. Each detection housing passes through a loading station, an inspection station, a pre-feed station, an unloading station for unqualified product, and an unloading station for qualified product, sequentially in the direction of rotation from an upper end of the rotary housing. The unloading station for qualified product is located at the lower end of the rotary housing.The detection housing extends radially along the rotary housing, and its outer diameter gradually decreases from the inner to the outer end. A clamping device is mounted within the detection housing and projects outwards. This device pulls a bevel gear located on the detection housing towards the inner end by moving the clamping device's extension element. A loading device for placing the bevel gear onto the detection housing is located at the loading station. A distance meter facing an end face of the bevel gear is located at the test station, and a pre-pulling device for pulling the bevel gear on the detection housing towards the outer end is located at the pre-pulling station. The clamping device includes an upper sliding block and a lower sliding block, which are slidably mounted inside the detection housing.The upper sliding block is located near the outer end of the detection housing and is opposite the lower sliding block. Between the upper and lower sliding blocks are at least two extension elements evenly distributed around the circumference of the detection housing. Each extension element comprises an upper connecting rod and a lower connecting rod, with one end of the upper connecting rod pivotally connected to the upper sliding block; another end of the upper connecting rod pivotally connected to an end of the lower connecting rod; and another end of the lower connecting rod pivotally connected to the lower sliding block. Through-holes for the passage of the upper and lower connecting rods are formed in a side face of the detection housing, the through-holes being elongated slots extending longitudinally along the detection housing.A spring is arranged on the lower sliding block, on a side away from the upper sliding block, with one end of the spring fixed to the detection housing and another end of the spring fixed to the lower sliding block; furthermore, the clamping device includes a detection air cylinder with which the upper sliding block can be moved.
[0006] Using the loading device according to the invention, the bevel gear is positioned on the detection housing at the loading station. The detection housing and the bevel gear are moved to the test station by the rotation of the rotating housing; furthermore, the clamping device is pushed out of the detection housing, and the bevel gear on the detection housing is pulled to its inner end by the movement of the clamping device's extension element. Since the outer diameter of the detection housing decreases gradually from the inner end to the outer end, the outer diameter of the detection housing, which corresponds to the end stop position of the bevel gear, corresponds to the inner diameter of an inner bore of the bevel gear. It can be determined whether the inner diameter of the bevel gear meets the specifications by detecting the position of the bevel gear with the distance sensor.
[0007] The detection housing moves to the pre-drawing station, and the bevel gear on the detection housing is pulled to the outer end by the pre-drawing device. Simultaneously, the extension element of the clamping device also moves to the outer end, thus ensuring that the bevel gear cannot fall off.
[0008] The ends of the detection housings at the unloading station for non-qualified products and at the unloading station for qualified products point downwards. If the inner bore dimension of the bevel gear does not meet the specifications, the retracting element retracts as soon as the detection housing moves towards the unloading station for non-qualified products, and the bevel gear falls into the unloading station for non-qualified products. If the inner bore dimension of the bevel gear meets the specifications, the retracting element retracts as soon as the detection housing moves towards the unloading station for qualified products, and the bevel gear falls into the unloading station for qualified products.
[0009] In the present embodiment, eight detection housings are provided, so that there is a detection housing at each of the stations at all times, thereby achieving maximum operational efficiency.
[0010] According to the invention, the upper and lower sliding blocks are arranged to slide inside the detection housing. At maximum distance between the upper and lower sliding blocks, the angle between the upper and lower connecting rods increases, allowing them to retract into the detection housing. As the upper and lower sliding blocks approach each other, the angle between them decreases, causing them to protrude from the detection housing.When the detection air cylinder moves the upper sliding block towards the inner end, the spring force acting on the lower sliding block holds it stationary, causing the hinge section between the upper and lower connecting rods to protrude from the detection housing. When the upper and lower sliding blocks make contact, they move together towards the inner end, pulling the bevel gear towards the inner end and thus achieving position detection at the test station. When the bevel gear reaches a pre-travel position, the detection air cylinder moves and holds both the upper and lower sliding blocks towards the outer end until the spring returns to its natural state.At this point, the hinge element between the upper and lower connecting rods still protrudes from the detection housing. The bevel gear can now be moved towards the outer end by the pre-extraction device. Once the bevel gear reaches the unloading station for unqualified product or the unloading station for qualified product, the detection pneumatic cylinder acts on the upper sliding block, moving it further towards the outer end. The upper sliding block is then separated from the lower sliding block by the force of the spring, causing the hinge element between the upper and lower connecting rods to retract into the detection housing, thus facilitating the bevel gear's descent.
[0011] In some embodiments, one end of the detection air cylinder is connected to the interior of the rotary housing, and another end of the detection air cylinder is connected to the upper sliding block after passing through the lower sliding block. In the present technical embodiment, the detection air cylinder is connected to the upper sliding block, with the cylinder being guided through the lower sliding block, and the upper sliding block is moved towards the lower sliding block by retracting the detection air cylinder.
[0012] In some embodiments, the loading device includes a feed conveyor located above the loading station and a fixed guide arc plate; the guide arc plate is located at one end of the feed conveyor parallel to an arc end of the feed conveyor; the distance between the guide arc plate and the end of the feed conveyor is adapted to the thickness of the bevel gear; the loading device further includes a fixed deflector plate located below the feed conveyor; a discharge opening is provided between the deflector plate and the lower end of the guide arc plate.In the present technical embodiment, the distance between the guide plate and the end of the feed conveyor is adapted to the thickness of the bevel gear. The feed conveyor transports the bevel gear into a position between the guide plate and the end of the conveyor, where it falls due to gravity, slides along the inside of the guide plate, rotates, and finally comes to rest against the deflection plate. The bevel gear falls through the opening between the deflection plate and the lower end of the guide plate and is pushed onto the detection housing, so that the bevel gear is precisely positioned on the detection housing.
[0013] In some embodiments, a tangential plane is arranged horizontally at the lower end of the guide arc plate; lateral deflection plates are fixedly connected to two sides of the guide arc plate, and the distance between the two lateral deflection plates is adapted to the outer diameter of the bevel gear. In the present embodiment, the tangential plane at the lower end of the guide arc plate is arranged horizontally, so that the bevel gear sliding towards the lower end is held horizontally, and the lateral deflection plates provide left and right guidance.
[0014] In some embodiments, the pre-drawing device comprises a fixed pre-drawing air cylinder and a pre-drawing block that is rigidly connected to a telescopic shaft of the pre-drawing air cylinder. A pre-drawing plate, which can rotate freely about the axis of the pre-drawing air cylinder, is slid onto the pre-drawing block; a plurality of clamping grooves, evenly distributed around the circumference of the pre-drawing plate, are formed in the outer ring of the pre-drawing plate, each clamping groove being adapted to the detection housing; and the pre-drawing air cylinder is arranged parallel to the detection housing at the pre-drawing station and is located on a side face of the detection housing. In the present embodiment, the clamping groove is adapted to the detection housing.As the detection housing moves downwards towards the pre-drawing station, the pre-drawing plate is moved so that it rotates around the detection housing by a certain angle, so that the clamping grooves on the outer ring of the detection housing are engaged, and the pre-drawing plate is guided so that it moves through the extension and retraction of the pre-drawing air cylinder, thereby pulling the bevel gear to the outer end.
[0015] In some embodiments, a container for non-compliant products is located below the unloading station for unqualified products, and an unloading conveyor belt is located below the unloading station for qualified products. In the present embodiment, the unqualified products fall into the container for unqualified products, and the qualified products are transported further via the unloading conveyor belt, thus enabling automated transport and simplifying subsequent processing.
[0016] In some embodiments, a rotating shaft is provided in the center of the rotary housing, which is connected to a support frame; the rotary drive comprises a driven gear fixedly connected to the rotating shaft, a rotary motor fixedly connected to the support frame, and a drive gear mounted on the rotary motor, the drive gear being in mesh with the driven gear. In the present invention, the rotation of the rotary housing is effected via the rotary motor and the drive gear acting on the driven gear.
[0017] In some embodiments, the outer end of the detection housing is tapered. In the present embodiment, the outer end of the detection housing is tapered so that the bevel gear can be easily slid onto the detection housing.
[0018] A procedure for using the integrated bevel gear conveying and quality measurement device comprises the following steps: a. Transport of the bevel gear by the feed conveyor to a position between the guide arch plate and the end of the feed conveyor; ejection / fall of the bevel gear by gravity, sliding of the bevel gear along an inner surface of the guide arch plate, turning over and finally stopping at the deflection plate; fall of the bevel gear through the discharge opening between the deflection plate and the lower end of the guide arch plate to place or slide the bevel gear onto the detection housing at the loading station; b. Moving or advancing the upper sliding block by the detection air cylinder towards the inner end, so that the hinge element consisting of the upper and lower connecting rods protrudes from the detection housing; moving the upper connecting rod and the lower connecting rod together towards the inner end when the upper sliding block comes into contact with the lower sliding block, thereby pulling the bevel gear towards the inner end; and furthermore, moving the detection housing with the bevel gear to the test station by rotating the rotating housing; c. Measuring the position of the bevel gear by the distance measuring device located at the test station to determine whether the inner diameter of the bevel gear meets the specifications or not, and subsequently moving the detection housing and the bevel gear to the pull-out station; d. Pulling the bevel gear towards the outer end by the pulling device, so that a gap remains between the inner bore of the bevel gear and the detection housing, and furthermore, moving the upper connecting rod and the lower connecting rod towards the outer end by the detection air cylinder; e. Moving the detection housing with the bevel gear to the unloading station for unqualified products and the unloading station for qualified products by rotating the rotating housing; moving the upper sliding block further towards the outer end, in the event that the detection housing moves to the unloading station for unqualified products because the size of the inner bore of the bevel gear does not meet the specifications; this causes the upper sliding block to move away from the lower sliding block under the action of a spring force, so that the hinge element, composed of the upper connecting rod and the lower connecting rod, engages in the detection housing, whereupon the bevel gear falls into the unloading station for unqualified products; f. The upper sliding block is moved further towards the outer end by the detection air cylinder if the size of the inner bore of the bevel gear meets the specifications, causing the detection housing to move to the eligibility product discharge station; this results in the separation of the upper sliding block from the lower sliding block under the force of the spring, so that the hinge element, consisting of the upper connecting rod and the lower connecting rod, engages in the detection housing and the bevel gear is dropped into the eligibility product discharge station.
[0019] The present invention has the following advantageous effects: According to the integrated bevel gear conveying and quality detection device and the method for its use, the bevel gear is pushed onto the detection housing and guided by rotation of the rotating housing to the loading station, inspection station, pre-pulling station, unloading station for unqualified products, and unloading station for qualified products; the outer diameter of the detection housing tapers gradually from the inner end to the outer end; the position of the bevel gear can be determined with the aid of the distance sensor, and thus it can be determined whether the inner diameter of the bevel gear meets the specifications; according to this determination, the qualified and unqualified products are positioned and moved to achieve an integrated transport and quality detection of bevel gears.

DESCRIPTION OF THE EXECUTION FORMS
[0020] In order to clearly highlight the technical features of the present invention, it will be described below on the basis of specific implementation modes.
[0021] In describing the present invention, it should be understood that the terminology used herein serves only to describe certain embodiments and is in no way to be understood as a limitation. The terms "a" or "a / an" used here are to be understood in the singular or plural. It should be noted that the terms "middle", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside", etc.The orientation or position relations shown in the accompanying drawings, or listed as orientation or position relations in which the product of the present invention is commonly used, are provided for the sake of simplicity to describe the present invention and to simplify the description, and do not mean or imply that the device or element in question must have a particular orientation or must be constructed and operated in a particular orientation.
[0022] As in Fig. 1 to Fig. As shown in Figure 9, the present invention provides an integrated bevel gear conveying and quality detection device and a method for its use. The integrated device includes a rotary housing 1 and a rotary drive for rotating the rotary housing 1 about a horizontal axis. Eight detection housings 4 are fixed to an outer ring of the rotary housing 1 and arranged evenly distributed in the circumferential direction.
[0023] From the Fig. Figure 2 shows a rotating shaft mounted in the center of the rotary housing 1. The rotating shaft is connected to a support frame 13. The rotary drive consists of a driven gear 14 fixed to the rotating shaft, a rotary motor 16 fixed to the support frame 13, and a drive gear 15 mounted on the rotary motor 16. The drive gear 15 meshes with the driven gear 14. The diameter of the drive gear 15 is smaller than that of the driven gear 14, resulting in a reduction in rotational speed and an increase in torque.
[0024] The detection housing 4 extends radially along the rotating housing 1, and its outer diameter gradually decreases from the inner to the outer end. The length of the detection housing 4 should be sufficiently long so that its diameter changes only slowly. Therefore, the influence of the thickness of the bevel gear 18 can be neglected, allowing for accurate measurement regardless of which end of the bevel gear 18 is facing downwards.
[0025] The outer end of the detection housing 4 is the end furthest from the rotating housing 1, and the inner end of the detection housing 4 is the end closest to the rotating housing 1. The outer end of the detection housing 4 has a tapered shape with a sharp point at the end, which facilitates sliding / fitting the bevel gear onto the detection housing 4.
[0026] The detection housing 4 passes through a loading station, a testing station, a pre-loading station, an unloading station for unqualified products, and an unloading station for qualified products, sequentially in the direction of rotation starting from the top of the rotary housing 1. The unloading station for qualified products is located at the bottom of the rotary housing 1. The loading station is located at the top of the rotary housing 1. The loading station, testing station, pre-loading station, unloading station for unqualified products, and the unloading station for qualified products are evenly distributed within a 180-degree radius; the angle formed between adjacent stations is 45 degrees, so that with each 45-degree rotation, the rotary housing 1 is positioned above a station and the detection housing 4 passes through each station, thus ensuring maximum efficiency of the operational sequence.
[0027] Below the unloading station for unqualified product is a container 22 for receiving unqualified product, wherein a product that does not meet the specifications falls from the unloading station for unqualified product and is received in the container 22 for unqualified product.
[0028] A discharge conveyor belt 21 is located below the discharge station for qualified product; from the discharge station for qualified product, this falls onto the discharge conveyor belt 21 and is directed to the next processing step.
[0029] A clamping device is arranged in the detection housing 4, which can protrude from the detection housing 4 and pulls / moves a bevel gear 18 located on the detection housing 4 towards the inner end by means of the movement of the extension element of the clamping device.
[0030] The clamping device comprises an upper sliding block 5 and a lower sliding block 6, which are slidably arranged inside the detection housing 4. The detection housing 4 has a cylindrical bore inside. The upper sliding block 5 is located near the outer end of the detection housing 4 and is opposite the lower sliding block 6. Both the upper sliding block 5 and the lower sliding block 6 have a cylindrical shape that is adapted to the inner bore of the detection housing 4.
[0031] At least two stretching elements, evenly distributed in the circumferential direction, are arranged between the upper sliding block 5 and the lower sliding block 6. In the present embodiment, two stretching elements are provided and arranged symmetrically to ensure a uniform tensile force for moving the bevel gear.
[0032] Each extension element comprises an upper connecting rod 7 and a lower connecting rod 8. One end of the upper connecting rod 7 is pivotally connected to the upper sliding block 5. A hinge element is perpendicular to an axis of the detection housing 4. The other end of the upper connecting rod 7 is pivotally connected to one end of the lower connecting rod 8. The other end of the lower connecting rod 8 is pivotally connected to the lower sliding block 6. Through holes 10 for the passage of the upper connecting rod 7 and the lower connecting rod 8 are formed in a side face of the detection housing 4. The through holes 10 are elongated holes extending longitudinally along the detection housing 4.
[0033] A spring 9 is arranged on the lower sliding block 6, on a side furthest from the upper sliding block 5. One end of the spring 9 is fixedly connected to the detection housing 4, the other end of the spring 9 is fixedly connected to the lower sliding block 6, so that the spring 9 has three states: a compressed state, a tensioned state and a natural (unloaded) state.
[0034] Furthermore, the clamping device includes a detection air cylinder 3 with which the upper sliding block 5 can be moved. One end of the detection air cylinder 3 is connected to the interior of the rotary housing 1, and another end of the detection air cylinder is connected to the upper sliding block 5 after passing through the lower sliding block 6. In the present embodiment, a telescopic shaft of the detection air cylinder 3 is fixedly connected to the upper sliding block 5, and the other end of the detection air cylinder 3 is connected to the central block 2 located in the center of the rotary housing 1.
[0035] The loading station includes a loading device for mounting the bevel gear 18 onto the detection housing 4. The loading device comprises a feed conveyor belt 17 located above the loading station and a fixed guide arc plate 19. The feed conveyor belt 17 is a conveyor belt with a drive drum at its end, giving the end of the feed conveyor belt 17 a 180° arc shape.
[0036] The guide plate 19 is located at the end of the feed conveyor 17, parallel to the arc of the end of the feed conveyor 17. The distance between the guide plate 19 and the end of the feed conveyor 17 is adapted to the thickness of the bevel gear 18, so that the bevel gear 18 is guided slidably within the guide plate 19. A horizontal tangential plane is provided at the lower end of the guide plate 19. Lateral deflection plates are fixed to two sides of the guide plate 19. The distance between the two lateral deflection plates corresponds to the outer diameter of the bevel gear 18.
[0037] Furthermore, the loading device includes a fixed deflection plate 20. The deflection plate 20 is arranged vertically and is located below the feed conveyor belt 17. A discharge opening is thus formed between the deflection plate 20 and the lower end of the guide arch plate 19. As the bevel gear slides towards the discharge opening, it strikes the deflection plate 20 and remains there briefly, whereupon it falls through the discharge opening in a horizontal position and is pushed onto the detection housing 4.
[0038] As in Fig. As shown in Figure 4, a distance meter 12 is mounted on the test station, facing an end face of the bevel gear 18. A distance meter mounting plate 11 serves to attach the distance meter 12, with the aid of which the position of the bevel gear 18 on the detection housing 4 is determined.
[0039] At the pre-drawing station, a pre-drawing device is located, which can pull the bevel gear 18 on the detection housing 4 to its outer end. The pre-drawing device has an attached pre-drawing air cylinder 23 and a pre-drawing block 24, which is rigidly connected to the telescopic shaft of the pre-drawing air cylinder 23. The pre-drawing air cylinder 23 is arranged parallel to the detection housing 4 at the pre-drawing station and is located on the side surface of the detection housing 4.
[0040] The pre-drawing block 24 has a cylindrical shape and is rigidly connected at its end face to the telescopic shaft of the pre-drawing air cylinder 23. A pre-drawing plate 25 is slid onto the pre-drawing block 24 and can rotate freely about the axis of the pre-drawing air cylinder 23. The pre-drawing plate 25 is circular and connected to the pre-drawing block 24 centrally via a bearing.
[0041] As in Fig.As shown in Figure 8, several clamping grooves are formed in the outer ring of the pre-drawing plate 25, evenly distributed in the circumferential direction. Each clamping groove is adapted to a detection housing 4. In the present embodiment, the clamping grooves are arcuate, and the center angles of the clamping grooves are between 120 and 160 degrees. The clamping grooves are coaxial with the outer rings of the detection housings 4. Six clamping grooves are provided. When the detection housing 4 moves downwards, the pre-drawing plate 25 with the adjacent clamping grooves is pressed downwards, causing the pre-drawing plate 25 to rotate and the clamping grooves to engage in the outer ring of the detection housing 4. Subsequently, the bevel gear is pulled to its outer end by the extension and retraction of the pre-drawing air cylinder 23, which then returns to its initial position.
[0042] A procedure for using the integrated bevel gear conveying and quality measurement device comprises the following steps: a. The bevel gear is transported by means of the feed conveyor belt to a position between the guide arch plate and the end of the feed conveyor belt; the bevel gear is dropped / dropped by gravity, slides along an inner surface of the guide arch plate, turns over and finally stops at the deflection plate; the bevel gear falls through the discharge opening between the deflection plate and the lower end of the guide arch plate and is placed on or pushed onto the detection housing at the loading station; b. The upper sliding block is moved towards the inner end by the detection air cylinder, so that the hinge area located between the upper connecting rod and the lower connecting rod protrudes from the detection housing; when the upper sliding block collides with the lower sliding block, the upper connecting rod and the lower connecting rod move together towards the inner end and pull the bevel gear towards the inner end, and at the same time the detection housing and the bevel gear are moved to the test station by rotation of the rotating housing; c. Whether the inner diameter of the bevel gear meets the specifications or not can be determined by measuring the position of the bevel gear using the distance measuring device located at the test station, and then the detection housing and the bevel gear are moved further to the extraction station; d. The movement of the bevel gear towards the outer end is carried out by the pre-drawing device, so that a gap remains between the inner bore of the bevel gear and the detection housing, and furthermore the upper connecting rod and the lower connecting rod are moved towards the outer end by the detection air cylinder; e. The detection housing with the bevel gear is moved to the unloading station for unqualified products and the unloading station for qualified products by rotating the rotating housing; the upper sliding block is moved further towards the outer end as the detection housing moves to the unloading station for unqualified products because the size of the inner bore of the bevel gear does not meet the specifications; this causes the upper sliding block to move away from the lower sliding block under the action of a spring force, so that the hinge element, composed of the upper connecting rod and the lower connecting rod, engages in the detection housing, whereupon the bevel gear falls into the unloading station for unqualified products; and f. If the size of the inner bore of the bevel gear meets the specifications, during the movement of the detection housing to the eligibility product discharge station, the upper sliding block is moved further towards the outer end by the detection air cylinder; this causes the upper sliding block to separate from the lower sliding block under the force of the spring, so that the hinge element consisting of the upper connecting rod and the lower connecting rod engages in the detection housing and the bevel gear is dropped into the eligibility product discharge station.
