Description

Technical Field

[0001] The invention belongs to the technical field of wheel hub manufacturing and relates to a positioning and turning detection device for a high-toughness wheel hub intelligent conveyor line. Background Art

[0002] The wheel hub is a product with a symmetrical shape. It needs to be processed symmetrically during the processing, so either the wheel hub workpiece needs to be turned over, or the tools and tools used to process the wheel hub need to be moved to the other side of the wheel hub.

[0003] A wheel hub production line includes multiple processes such as turning, milling, painting, cleaning, and inspection. Among them, painting, cleaning, and inspection generally need to be performed on both sides of the hub. For example, the painting process generally uses two nozzles. When the hub passes by, the two nozzles simultaneously spray paint on the hub passing between them. The cleaning process also sprays detergent from both sides of the hub. After the hub is cleaned by brushes on both sides, it is cleaned by spraying clean water on both sides.

[0004] This is especially true for the inspection process of wheel hubs. The performance of wheel hubs includes mechanical properties, smoothness, flatness and other properties. In the current market, various sensors are generally used to complete the performance inspection process (such as visual sensors to detect smoothness, flatness of the outer coating, color and brightness of the outer coating, and pressure sensors to detect mechanical properties, etc.). Without exception, both symmetrical sides of the wheel hub need to be processed. The equipment currently used to inspect the performance of the wheel hub usually places two symmetrically swung inspection tools on both sides of the wheel hub workpiece (the inspection tools here are generally sensors), and then let the wheel hub pass between the two sensors for inspection.

[0005] If the budget or space is limited, there is only one processing tool (processing tools refer to paint nozzles, cleaning fluid and water nozzles, visual inspection sensors, etc. used to complete the processing of the wheel hub) for processing and production, that is, the wheel hub can only be processed from one side, then there are only two solutions: the first solution is to move the wheel hub to the initial position after the assembly line processing is completed, turn it over, clamp it and fix it once, and then run the processing line again. This is a very clumsy method, because many processing lines cannot run one side of the assembly line and then turn it over for the second operation (for example, painting and cleaning must be done on one side). After painting, you can immediately start painting the other side. You cannot spray the left side first, then clean the left side, then spray the right side, and then clean the right side). Therefore, this method cannot allow the workpiece to automatically complete an entire automatic processing line. After each processing line is completed, it needs to be withdrawn and then turned over and clamped again; the second is to use the method of reversing the processing tool, that is, after the processing tool completes the processing on one side of the wheel hub, it automatically shifts to the other side of the wheel hub for processing. The processing tool needs to move within a large range, so the internal space of the equipment is very high. If this method is used, the spatial width of the equipment is actually similar to that of using processing tools on both sides.

[0006] Therefore, the applicant believes that if there is a device on the assembly line where the wheel hub passes that can turn over the wheel hub regularly (regular means that it can turn over the wheel hub at a specified time in each process), then the above processes can actually be achieved by processing tools on one side, which can free up the width of the equipment and save the two processing tools required by conventional equipment to only one. Moreover, under this design idea, the most important issue to be solved is the detection process. Summary of the invention

DETAILED DESCRIPTION

[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0035] like Figures 1 to 3 As shown, the positioning and flipping detection device of the high-toughness wheel hub intelligent conveyor line includes multiple groups of conveying components connected end to end and displacement blocks 1 that can perform displacement activities on the conveying components. The displacement block 1 is moved on the conveying component by a linear transmission mechanism. The vertical direction (vertical) rotation of the displacement block 1 is provided with a flipping shaft 2, and the flipping shaft 2 passes through the displacement block 1 above and below. The part of the flipping shaft 2 located in the displacement block 1 has a stepped shaft (the presence of the stepped shaft can prevent the flipping shaft 2 from detaching from the displacement block 1 up and down), and the bottom of the flipping shaft 2 is provided with a clamping component 3 for clamping and fastening the wheel hub, and the edge of each group of conveying components is provided with a variety of inspection equipment for detecting different types of performance of the wheel hub.

[0036] like Figure 2 and Figure 3As shown, the conveying component includes a conveying rail 4, which has a track groove 5 horizontally opened in the horizontal direction. A track body 15 with the same longitudinal cross-section as the track groove 5 is fixedly provided on the side of the displacement block 1. The track body 15 is slidably set in the track groove 5. A straight bar 6 is also horizontally provided on the conveying rail 4, and a fracture is opened on the straight bar 6. A flip rack 7 is fixed in the fracture, and a flip gear 8 is fixed on the upper end of the flip shaft 2. In the process of accompanying the displacement block 1 displacement, the flip gear 8 is close to the outer edge of the straight bar 6. In the process of the flip gear 8 passing through the flip rack 7, the two cooperate to rotate the flip gear 8 180 degrees.

[0037] like Figures 4 to 6 As shown, in the process that the flipping gear 8 above the flipping shaft 2 passes through the flipping rack 7, due to the cooperation of the flipping gears 8, the flipping shaft 2 will rotate along with the flipping gear 8. As long as the flipping gear 8 can be flipped 180 degrees after completely passing through the flipping rack 7, and the clamping part 3 is located below the flipping shaft 2, the wheel hub is clamped on the clamping part 3, so the wheel hub will flip 180 degrees to complete the flipping function.

[0038] like Figure 2 and Figure 3 As shown, the conveying component also includes two positioning rails 9 fixedly arranged in parallel with the conveying rail 4, and the two positioning rails 9 are linearly symmetrically arranged relative to the path through which the flipping shaft 2 passes, and a positioning channel 10 is opened on the positioning rails 9. Two groups of extension rods 11 are longitudinally symmetrically fixed at the lower end of the flipping shaft 2, and a positioning rod 12 is vertically fixed at the end of the extension rod 11. The two positioning rods 12 are respectively located in the two groups of positioning channels 10, and a truncation point 13 is provided on the positioning rail 9. The truncation point 13 is located directly below the position of the flipping rack 7. After the positioning rod 12 moves to the truncation point 13, it is no longer limited by the positioning rail 9. The positioning rod 12 will be on the path of another positioning channel 10 after the flipping shaft 2 is flipped 180 degrees.

[0039] In the above description, the horizontal and vertical directions are, as the name implies, two directions perpendicular to each other, and the vertical direction is interpreted as a numerical direction. If interpreted from the perspective of the three-axis relationship, the horizontal, vertical, and vertical directions represent the X-axis, Y-axis, and Z-axis respectively.

[0040] like Figure 2 and Figure 3 As shown, when the turning gear 8 does not pass through the turning rack 7, the positioning rod 12 is restricted by the positioning rail 9 in the positioning channel 10, so the turning shaft 2 cannot rotate, forming a self-locking effect.

[0041] like Figures 4 to 6As shown, when the positioning rod 12 moves to the cutoff point 13, because the positioning rod 12 is no longer restricted by the positioning rail 9, the flip shaft 2 is allowed to rotate at this time, and the flip rack 7 is just above the cutoff point 13, so the flip rack 7 and the flip gear 8 can interact with each other to rotate the flip shaft 2. When the flip shaft 2 rotates 180 degrees, the two positioning rods 12 will exchange positions, and each positioning rod 12 will enter another positioning channel 10 and will be locked again after entering.

[0042] The edge of the cutoff portion 13 of the positioning rail 9 is provided with an arc-shaped guide surface 14, which can guide the slightly offset positioning rod 12 into the positioning channel 10. The function of the arc-shaped guide surface 14 is as follows: Figure 6 As shown, it can be seen that when the flipping shaft 2 completes the flipping, the positions of the two positioning rods 12 are interchanged, but at this time due to error factors, the two positioning rods 12 may not be exactly on the path of the positioning channel 10, and in many cases there will be slight deviations. At this time, the positioning rod 12 will be slowly introduced into the positioning channel 10 after contacting the arc-shaped guide surface 14 to ensure that the flipping shaft completes the 180-degree precise flipping function.

[0043] The clamping component 3 includes a U-shaped bracket, a clamping shaft, a left clamping block, a right clamping block, and a fixing structure. The U-shaped bracket is inverted, the clamping shaft is mounted at the bottom of the U-shaped bracket and is used to cover the wheel hub, the left clamping block and the right clamping block are detachably clamped on both sides of the clamping shaft and are used to clamp the wheel hub between them, and the fixing structure is used to fix the left clamping block and the right clamping block relative to the clamping shaft. The function of the clamping component 3 is to clamp the wheel hub, and it acts as a clamp.

[0044] The fixing structure is any one of the mortise and tenon mechanism, the threaded disk mechanism, and the electromagnetic adsorption mechanism. The fixing structure has various forms. As long as the fixing functions of the clamping block and the right clamping block are completed, common fixing parts on the market are feasible.

[0045] The linear transmission mechanism is any one of a cylinder mechanism, an oil cylinder mechanism, a gear rack mechanism, and a screw slider mechanism. Its function is to realize the linear motion of the displacement block 1, so a linear drive component can be used. Because the linear transmission mechanism belongs to a very mature existing technology, it is not reflected in the drawings of the present invention.

[0046] One or more of the inspection equipment can be replaced by a paint spraying equipment, and one or more of the inspection equipment can be replaced by a cleaning equipment. The paint spraying equipment, the cleaning equipment, and the inspection equipment can all be set on the intelligent conveyor line to complete various processes.

[0047] The longitudinal section of the track groove 5 is trapezoidal, and the upper base of the trapezoid is located on the side of the conveying rail 4 , so that the conveying rail 4 will not separate from the track groove 5 .

[0048] The above is the structure and working principle of the positioning flipping detection device.

[0049] In addition, in the processing of the wheel hub, such as turning and polishing, the tool needs to be attached to the wheel hub for processing, so the wheel hub needs to be clamped by high-strength clamping parts. The high-strength clamping parts here are generally large shaft clamping tools such as three-jaw chucks. However, in the assembly line of processing processes such as cleaning and testing, the wheel hub does not need to be clamped particularly tightly, because there is no high-strength extrusion and adhesion between the tool and the wheel hub, so in this case, the strength requirements of the clamping tool are not high.

[0050] The present invention is used in the occasion where the clamping strength is not high, so it is not necessary to use a high-strength clamping tool such as a chuck.

[0051] However, there are no clamping parts specifically used for low-strength clamping of wheel hubs on the market, or the use of simple structure clamping tools requires cumbersome operations (to clamp the wheel hub, clamping parts are definitely needed on both sides. In general, the operator needs to manually place the wheel hub on the positioning part and then use two clamping parts to clamp the object on both sides, so the operation process is not completed in one go).

[0052] Just like the clamping parts mentioned in this article, after simplifying them, only three objects are needed: a middle shaft and two clips on both sides of the shaft. The clips on both sides can be pre-fixed higher, and then the wheel hub is put on and then the other clip is put on to clamp the middle wheel hub. However, this operation method is still not very convenient, because the clip needs to be locked relative to the shaft, so a locking part needs to be designed. With more objects, the process of workers using it will be complicated.

[0053] Therefore, there is an urgent need to develop a convenient wheel hub clamping tool to achieve operational convenience during the low-strength wheel hub clamping process.

[0054] In this regard, this article also provides a clamping device for use in detecting such low clamping strength requirements, and the clamping device can be directly used to replace the clamping components mentioned in this article.

[0055] like Figures 7-10As shown, the clamping device includes a clamping shaft 1A, a clamping ring 2A, an adjusting block 3A, a circular adjusting rod 4A and a plurality of groups of claw assemblies symmetrically arranged on the clamping shaft 1A. The clamping ring 2A is fixedly sleeved on the tail end of the clamping shaft 1A. The transverse cross-section of the adjusting block 3A is a regular polygon based on the number of claw assemblies (for example, in this embodiment, there are four groups of claw assemblies, which are symmetrically distributed in a cross shape, so the regular polygon here is actually a square). A through hole 5A with the same transverse cross-section as that of the adjusting block 3A is provided in the center of the front end face of the clamping shaft 1A. The adjusting block 3A is slidably arranged in the through hole 5A. An axial hole is provided in the center of the rear end face of the clamping shaft 1A. The axial hole is connected to the through hole 5A. The circular The adjusting rod 4A is rotatably arranged in the shaft hole and can only rotate relative to the clamping shaft 1A. A screw hole 6A is provided in the center of the adjusting block 3A. The front end outer ring of the circular adjusting rod 4A has a thread, and the thread of the circular adjusting rod 4A fits in the screw hole 6A of the adjusting block 3A. After the circular adjusting rod 4A is rotated, the adjusting block 3A can move in the through hole 5A through the action of the threaded screw hole 6A. The front end center of the clamping shaft 1A is symmetrically provided with notches 7A with the same number as the claw assemblies. The claw assemblies are located in the notches 7A. The claw assemblies include clamping claws 8A. The clamping claws 8A realize the clamping function under the movement of the adjusting block 3A, and the two sides of the clamped wheel hub original are attached between the clamping claws 8A and the clamping ring 2A.

[0056] like Figure 7 and Figure 8 As shown, when in use, insert the center hole of the wheel hub from the left side into Figure 1 The clamping shaft 1A is shown in the figure, until the right side of the hub is attached to the clamping ring 2A, and then the circular adjusting rod 4A is rotated to first open the clamping claw 8A in the clamping claw assembly, and then the clamping claw 8A is moved to the right until it is attached to the left side of the hub, forming Figure 2 The position relationship shown.

[0057] Because a very strong clamping effect is not required, the clamping claw 8A only needs to provide a slight supporting force after it is attached to the wheel hub. Therefore, the length of the clamping claw 8A can be made very small, and it only needs to be opened beyond the clamping axis 1A. However, in order to facilitate understanding during the implementation process, the drawings in this article have lengthened the length of the clamping claw 8A.

[0058] The clamping claw 8A will perform two actions under the action of the circular adjusting rod 4A: first, it will be opened from the notch 7A of the clamping shaft 1A, and then it will move toward the direction of the clamping ring 2A to complete the clamping function. Therefore, the design of the clamping claw assembly requires certain design requirements.

[0059] like Figures 11 to 14As shown, the clamping claw assembly includes a rack 9A, a gear 10A, a retraction block 11A, a first spring 12A, and a second spring 13A in addition to the above-mentioned clamping claw 8A. The front end of the retraction block 11A is provided with a receiving opening 14A for accommodating the rack 9A, the gear 10A, and the clamping claw 8A. Rotary holes are provided on both sides of the receiving opening 14A of the retraction block 11A. A rotating shaft 15A is fixedly provided transversely on the clamping claw 8A. The clamping claw 8A is rotatably arranged on the rotating hole through the rotating shaft 15A. On the upper side, the rack 9A is fixedly arranged on the side of the adjusting block 3A, the gear 10A is fixedly sleeved on the rotating shaft 15A, the gear 10A is meshed with the rack 9A, the two ends of the first spring 12A are respectively fixed to the rack 9A and the end face of the accommodating opening 14A of the retracting block 11A, the two ends of the second spring 13A are respectively fixed to the outer end of the retracting block 11A and the end face of the notch 7A of the clamping shaft 1A, and the elastic potential energy of the second spring 13A is greater than the elastic potential energy of the first spring 12A;

[0060] When the retraction block 11A is at the initial position at the front end: the second spring 13A is in a fully-opened state and in this state the retraction block 11A is pushed to the front end relative to the clamping shaft 1A, the first spring 12A is in a fully-opened state and in this state the rack 9A is pushed to the front end relative to the retraction block 11A, and in this state the gear 10A is located at the rightmost end of the rack 9A, and the clamping claw 8A is completely buried in the accommodating opening 14A of the retraction block 11A;

[0061] When the retraction block 11A moves toward the rear end: the rack 9A first moves backward to drive the gear 10A to rotate so that the clamping claw 8A gradually rises from the accommodating opening 14A until it is in a vertical state, and at the same time the first spring 12A is squeezed until it is fully squeezed. The rack 9A then provides transmission power through the first spring 12A in the fully squeezed state to move the retraction block 11A to the right.

[0062] In the above description: the front end is the left end in the diagram, and the rear end is the right end in the diagram.

[0063] Figures 11 to 14 Demonstrates the entire clamping process (the illustrations in the demonstration hide the Fig. 9 In the clamping shaft 1A), during the clamping process, the operator rotates the circular adjusting rod 4A. Because the adjusting block 3A is limited in the through hole 5A, the adjusting block 3A moves back and forth in the through hole 5A toward the tail end of the clamping shaft 1A under the action of the threaded screw hole 6A (similar to the movement principle of the screw slider). In the attached figure, the adjusting block 3A moves rightward relative to the clamping shaft 1A, and then the position relationship of each part is rearranged to obtain the following information:

[0064] Adjustment block 3A: moves independently relative to the clamping shaft 1A, and is driven by a circular adjustment rod 4A to move in the through hole 5A of the clamping shaft 1A;

[0065] The retraction block 11A moves independently relative to the clamping shaft 1A, and has a tendency to move to the left due to the pressure provided by the second spring 13A;

[0066] Clamping claw 8A: It can flip relative to the retracting block 11A. However, due to the positional relationship between the gear 10A and the rack 9A, the position angle of the clamping claw 8A relative to the retracting block 11A is completely determined by the position of the gear 10A and the rack 9A.

[0067] Rack 9A: It is fixed to the adjusting block 3A. The rack 9A moves in the same way as the adjusting block 3A moves. However, the rack 9A is connected to the retracting block 11A through the first spring 12A. Therefore, the rack 9A can be used as an intermediate piece to connect the movements of the adjusting block 3A and the retracting block 11A, which can move independently relative to the clamping shaft 1A.

[0068] After analyzing the positional relationship of each component, it is easier to understand the movement process in detail. The movement process is as follows:

[0069] like Fig.11 As shown in the figure, the adjusting block 3A moves to the right, the rack 9A and the adjusting block 3A are fixed to each other, then the rack 9A will slide to the right, because the elastic potential energy of the second spring 13A is much greater than the elastic potential energy of the first spring 12A, so the second spring 13A still provides a large elastic force to keep the retraction block 11A always in the leftmost position, that is, the retraction block 11A can be regarded as fixed, and the clamping claw 8A is rotatably set on the retraction block 11A. In this process, the rack 9A moves to the right to make the gear 10A flip, and the gear 10A will gradually rise with the clamping claw 8A, and at the same time the first spring 12A is gradually compressed. This process is shown in FIG. Fig.12 As shown;

[0070] When the first spring 12A is compressed to a fully compressed state, the rack 9A moves rightward just enough to cause the gear 10A to flip 90°. At this time, the clamping claw 8A is in a fully erected state perpendicular to the axial direction of the clamping shaft 1A. Fig.13 As shown;

[0071] Then the adjusting block 3A continues to move rightward. Because the first spring 12A has been completely compressed, the force of the adjusting block 3A moving rightward is no longer applied to the first spring 12A to make it elastically compressed and deformed. The rightward movement of the retracting block 11A is applied to the retracting block 11A through the completely compressed first spring 12A, so that the retracting block 11A moves rightward. At the same time, the second spring 13A begins to be compressed and deformed. This process is the clamping process of gradually bringing the fully opened clamping claw 8A closer to the wheel hub. Fig.14 shown.

[0072] When the wheel hub needs to be unloaded, the circular adjusting rod 4A can be rotated in the reverse direction, and each component will return to its original position in time under the action of the first spring 12A and the second spring 13A.

[0073] From the above description, it can be known that the clamping device is extremely convenient to use. During the whole process, the worker only needs to perform two operations: the first is to put the wheel hub onto the clamping shaft 1A, and the second is to continuously rotate the circular adjustment rod 4A in the same direction, and then the wheel hub is directly clamped.

[0074] like Figure 7 and Figure 8 As shown, a limiting groove 16A is provided on the side wall of the notch 7A of the clamping shaft 1A, and a limiting strip is provided on the side of the retraction block 11A. The limiting strip is slidably embedded in the limiting groove 16A so that the retraction block 11A will not be separated from the clamping shaft 1A.

[0075] In order to improve reliability, the claw assembly has two gears 10A and two racks 9A, the two gears 10A are respectively fixed on the rotating shafts 15A on both sides of the clamping claw 8A, and the two racks 9A are respectively engaged with the two gears 10A. The racks 9A can also be fixedly connected together through a bottom block, and then the first spring 12A is connected to the bottom block. Because it is an integrated part, it is equivalent to the first spring 12A directly connecting with the rack 9A.

[0076] A circle of annular groove is also provided on the clamping shaft 1A of the middle outer ring of the shaft hole, and an annular body is provided on the outer ring of the circular adjustment rod 4A. The annular body is located in the annular groove so that the circular adjustment rod 4A can only rotate relative to the clamping shaft 1A.
