Description

Technical Field

[0001] This invention relates to the field of cage inspection technology, and in particular to an adjuster, a feeding conveyor, and a cage window inspection machine. Background Technology

[0002] Rolling bearings used in vehicles generally consist of four parts: an outer ring, an inner ring, rolling elements, and a cage. The cage plays a crucial role in resisting load pressure. Also called a ball cage, it is a circular ring with multiple windows distributed circumferentially. As an important component of the car's transmission system, its function is to transmit engine power from the transmission to the drive wheels, propelling the car at high speeds. The cage partially encloses all or part of the rolling elements; its main function is to isolate the rolling elements while guiding and holding them within the bearing. During use, the cage bears heavy loads, requires high transmission precision, and is also a safety component; therefore, quality control is extremely important during production. Currently, there are some devices on the market for testing cages, such as those for detecting the overall dimensions, window height, and width of the cage. Another example is the cage window burr, flash, and dent detection machine newly developed by the applicant. Because cages come in various sizes and models, the mechanical components of the testing equipment often need to be repositioned when changing batches of cages.

[0003] In mechanical equipment, especially equipment used to process workpieces of different sizes, adjusters are often designed for precise and convenient adjustment of the position of mechanical components. This allows the mechanical components to be adjusted to the appropriate position for the dimensional processing requirements of the batch of workpieces before operation. Most existing adjusters involve creating a complete lead screw channel on these mechanical components, and then using the rotation of the lead screw to drive the mechanical components for fine-tuning along the lead screw, or directly positioning the mechanical components on a guide rail. With current adjuster technology, each adjustment can only be made in increments of ten or twenty micrometers, unable to perform finer adjustments at the micrometer (mu) level. For workpieces or equipment with high precision requirements, repeated manual adjustments are necessary to achieve accurate positioning, or the operation may have to be carried out with relatively large errors, often resulting in low equipment efficiency, poor performance, and low workpiece yield.

[0004] In addition, conveying components are needed to achieve automation in testing equipment. Existing workpiece conveying equipment is generally conveyed by conveyor belts. The cage needs to be positioned according to the position of its window during testing. Ordinary conveyor belts only have the function of conveying during the conveying process and do not have the function of sorting the specific position of the workpiece. If the position is adjusted manually, it is not only inefficient and costly, but also unsafe. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to provide an adjuster, a feeding conveying device, and a cage window inspection machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An adjuster includes an adjusting guide rail, an adjusting slider disposed on the adjusting guide rail, and an adjusting screw disposed between the adjusting guide rail and the adjusting slider. The outer contour of the cross-section of at least the portion of the adjusting guide rail that mates with the adjusting slider is dovetail-shaped. The groove of the adjusting slider is a dovetail groove adapted to the dovetail-shaped portion of the adjusting guide rail. The adjusting screw passes between the adjusting guide rail and the adjusting slider, and a portion of the threaded hole that is screwed to the adjusting screw is formed in the adjusting guide rail as a bottom groove, and a portion is formed in the groove as a top threaded groove. The inner groove wall of the bottom groove that mates with the threaded circumference of the adjusting screw is a smooth arc-shaped surface. The top threaded groove has a thread that is screwed to the adjusting screw. The bottom groove and the top threaded groove are joined together to form a complete circular threaded hole.

[0008] Preferably, the axis of the threaded hole formed by the bottom hole groove and the top threaded hole groove is located in the bottom hole groove. The bottom hole groove has enlarged limiting grooves at both ends. The two ends of the adjusting screw are located in the two limiting grooves respectively, and one end is connected to an adjusting knob.

[0009] Preferably, a narrow, elongated elastic reinforcing groove is formed on the symmetrical center surface of the adjusting slider. The elastic reinforcing groove passes through the adjusting slider along the length direction of the adjusting guide rail and communicates with the top threaded hole groove. The blind end of the elastic reinforcing groove away from the adjusting screw is an enlarged arc-shaped anti-crack groove. A locking bolt is provided on the adjusting slider perpendicular to the length direction of the adjusting guide rail. The locking bolt passes through the adjusting slider and the elastic reinforcing groove to lock and limit the adjusting slider.

[0010] Preferably, the adjustment guide rail is provided with scale markings and / or model markings along its length.

[0011] A feeding conveying device includes a feeding conveyor belt, and further includes conveying guide rods disposed on both sides of the feeding conveyor belt, two symmetrically arranged positioning forks located in front of the feeding conveyor belt, an adjuster as described above, and an adjustment base assembly. The positioning forks are disposed on the adjuster, and the adjuster is disposed on the adjustment base assembly and can be moved back and forth along the length direction of the feeding conveyor belt by the adjustment base assembly carrying the adjuster and the positioning forks. The rear opposite surfaces of the two conveying guide rods are symmetrically provided with combing guide slopes that gradually approach each other from back to front, and the front opposite surfaces are symmetrically provided with discharge steps for increasing the spacing. The spacing between the discharge steps of the two conveying guide rods is greater than the spacing between the middle regions of the two conveying guide rods. When the positioning forks move into position in the direction of the feeding conveyor belt, at least the projection of the fork head portion of the positioning fork onto the plane containing the upper surface of the feeding conveyor belt can overlap with the upper surface of the feeding conveyor belt.

[0012] Preferably, the conveying guide rod is an inwardly arc-shaped comb structure with at least one side facing the center of the feed conveyor belt, and photoelectric switches (a6) are provided on both sides of the feed conveyor belt at positions corresponding to the discharge steps.

[0013] Preferably, the feed conveyor belt is also provided with guide rod adjustment seats on both sides. The guide rod adjustment seats are provided with guide rod height adjustment uprights that can be adjusted along the height direction through slots and bolts. A horizontally arranged guide rod spacing adjustment horizontal rod passes through the upper end of the guide rod height adjustment upright. The conveying guide rod is provided on the guide rod spacing adjustment horizontal rod. The top of the guide rod height adjustment upright is provided with a knob handle that can tighten the guide rod spacing adjustment horizontal rod.

[0014] Preferably, the positioning fork has a fork groove on its fork head that can mate with the window side edge of the retainer. The side of the fork groove near the center of the feed conveyor belt has an inner stop portion extending towards the feed conveyor belt, and the side away from the center of the feed conveyor belt has an inclined outer locking guide portion. The positioning fork is adjustablely connected to the rear end of the positioning fork via a slot and bolts along the length of the feed conveyor belt. The adjusting base assembly includes a base rail, an adjusting base that slides along the base rail, and a height adjusting plate on the adjusting base. The height adjusting plate has a slot along the direction of gravity. The adjusting guide rail is adjustablely connected to the height adjusting plate via a pad and the slot.

[0015] A cage window inspection machine includes the above-mentioned feeding conveying device.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In this application, the threaded hole in the adjuster that mates with the adjusting screw is formed by two parts: a bottom groove in the lower half and a top threaded groove in the upper half. A dovetail structure further limits the engagement of the components containing the threaded holes in the upper and lower halves—the adjusting guide rail and the adjusting slider—ensuring a tight and effective fit between the adjusting screw and the threaded hole. Since the bottom of the threaded hole is a smooth, unthreaded arc surface while the top is threaded, only the upper half of the thread engages with the adjusting screw; the lower half only needs to press against the adjusting screw. This significantly reduces friction with the adjusting screw, allowing for a smaller thread pitch at the top and the use of a finer-threaded adjusting screw. This makes adjustment easier, and the adjuster can achieve adjustments as fine as 5 micrometers per adjustment, compared to existing adjustments of only a few micrometers. This greatly improves adjustment accuracy and efficiency, achieving true micrometer-level fine-tuning. This is an effect that ordinary adjusters on the market cannot achieve. Furthermore, the adjuster of this application has been applied in actual production; the above data is derived from practical application.

[0018] 2. Based on the characteristic that the cage windows are concave relative to the top and bottom, this application utilizes the aforementioned specific conveyor guides to simultaneously transport and orient the cage. Specifically, during transport, the cage rotates along a gradually narrowing guide slope, causing the two opposing windows to be precisely engaged on the two opposing conveyor guides. Since the distance between the conveyor guides is less than the distance between the top or bottom edges of the two opposing windows of the cage, the cage's orientation is constrained during transport. When transported to the discharge step, a positioning fork is waiting at the front end of the infeed conveyor belt. At this point, the edges of the corresponding two windows of the cage engage with the positioning fork for positioning and restraint. The cage is now in position, and the infeed conveyor belt stops. To facilitate upward removal of the cage, a discharge step is provided on the conveyor guides, allowing the cage to disengage from the side restraints of the conveyor guides, with only the positioning fork providing orientation restraint, thus ensuring that the oriented cage always remains consistent. When upward removal is required, the positioning fork retracts and disengages from the cage, and then a moving device removes the cage from the infeed conveyor belt for testing.

Detailed Implementation

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The present invention will be further described below with reference to the accompanying drawings:

[0042] Example 1:

[0043] A cage window detection device includes a steel ball detection assembly. The steel ball detection assembly includes a first driving component, a first guide rail component, a pushing and moving component, and a steel ball 3 disposed at the front end of the pushing and moving component. The first guide rail component includes a first guide rail seat 41 and a first guide rail 42 disposed on the first guide rail seat. The pushing and moving component includes a movable seat 43 disposed on the first guide rail seat and movable along the first guide rail, and a pushing rod 44 connected to the front end of the movable seat. The steel ball is disposed at the front end of the pushing rod. The movable seat is connected to the first driving component and can reciprocate along the first guide rail through the drive of the first driving component. The first driving component is electrically connected to the main controller of the device.

[0044] The cage steel ball detection device also includes a base 1 and a reference component 2 disposed on the base. Multiple sets of steel ball detection components are arranged radially around the reference component on the base, with the steel balls facing the center of the reference component.

[0045] The retainer window mates with the steel ball during use. If the window's dimensional accuracy is not up to standard, the fit between the retainer window and the steel ball will not meet technical specifications, affecting later use. Existing equipment for measuring the height and width of the retainer window, while passing these dimensional checks, can still prevent the steel ball from being inserted due to burrs, flash, or dents. Current solutions rely on manual ball insertion with inconsistent force, i.e., manually pushing a steel ball into the retainer window. It takes approximately 30 seconds to complete the ball insertion test for multiple windows on one retainer. This manual method is not only inefficient but also labor-intensive. Furthermore, uneven force during insertion, without standardized force to distinguish defective products, may result in some defective products being put into use, affecting operational performance and service life.

[0046] This application allows for the placement of a reference component at the center of the base, followed by the radial arrangement of multiple sets of steel ball detection components corresponding to the number of windows on the retainer 01. During testing, the retainer 01 is placed horizontally on the reference component as required. The steel ball detection components, i.e., the first drive component, are then activated, driving the push-moving component to move along the first guide rail component. This causes the steel ball at the front end of the push rod to move towards the corresponding retainer window and extend into it for testing. If the steel ball cannot be pushed into the window, information is sent to the main controller, and then multiple sets of steel ball detection components retract, thus completing the testing of that window. Each window corresponds to one set of steel ball detection components, allowing each window to be tested simultaneously. The testing of a workpiece, from placement to completion, takes only five to six seconds, significantly improving testing efficiency. Furthermore, it can accurately detect which window is defective and send feedback to the main controller, which then controls the next step of the material sorting device for sorting and collection.

[0047] Example 2:

[0048] The difference from the above embodiments lies in that the reference assembly includes a base 21 and a detachable workpiece 22 mounted on the base. During installation, the outer diameter of the workpiece fits into the inner ring of the cage's bottom opening. The base can be fixed to the center of the machine base without disassembly, while the workpiece can be easily and quickly replaced according to different cage models (i.e., different bottom opening inner diameters). Similarly, the steel balls can also be replaced according to different cage models, thus enabling the device to adapt to various cage models. Generally, the workpiece is replaced when changing batches to test different cage models.

[0049] Example 3:

[0050] The difference from the above embodiment is that the top of the movable seat is provided with a bridging assembly, which includes a bridging base 51, an up-and-down adjusting guide rail 52 and an adjuster b1 provided on the bridging base, and a bridging rod 54 connected to the front end of the up-and-down adjusting guide rail and the adjuster, with the push rod provided at the front end of the bridging rod.

[0051] The bridge connecting rod and the upper and lower adjusting guide rails are detachably connected via an upper and lower adjusting slider 55 and a type shim 56. This allows adjustment of the distance between the steel ball at the front end of the bridge connecting rod and the moving seat by replacing the type shims of different thicknesses. Changing the type shim allows adjustment of the reciprocating position during steel ball testing for different types of cages, eliminating the need to adjust the reciprocating range of the pushing moving component relative to the first guide rail. For example, when testing cages from a previous batch with a larger inner diameter to a next batch with a smaller inner diameter, replacing the type shim with a thicker one ensures the steel ball's insertion depth into the window, guaranteeing accurate and effective testing. This rational layout makes the equipment more precise, compact, and easily adjustable.

[0052] Example 4:

[0053] The difference from the above embodiment is that the adjuster includes an adjusting guide rail b11 and an adjusting slider b12 disposed on the adjusting guide rail. The adjusting guide rail of the adjuster disposed on the bridge base is parallel to the upper and lower adjusting guide rail. When the cage is changed to a new batch, the position of the adjusting slider on the adjusting guide rail can be used to drive the bridge connecting rod to be adjusted up and down to reach the reference position required for the next batch of cages. The adjusting slider is connected to the bridge connecting rod through a side connecting rod 57, and the side connecting rod and the adjusting slider are adjustablely connected through a slot parallel to the axial direction of the push rod in the length direction. The slot ensures that when the model pad is changed, that is, when the bridge connecting rod is adjusted back and forth, the connection with the side connecting rod can also be adjusted, ensuring that the adjuster can effectively drive the bridge connecting rod to be adjusted and to perform reference positioning.

[0054] The adjustment mechanism allows the bridge connecting rod of the push rod to be adjusted not only in the front and rear reference positions, but also in the upper and lower reference positions when changing the batch of the cage being tested, thus ensuring applicability to different models of cages.

[0055] Example 5:

[0056] The difference from the above embodiment is that the bridge connecting rod is an L-shaped connecting rod, the front end of the bridge connecting rod is a vertical rod part 541, the rear side of the vertical rod part is provided with a push base plate 542, the push rod passes through the vertical rod part and is connected to the push base plate, the push base plate is also provided with a force measuring rod 543, the force measuring rod is arranged parallel to the push rod and also passes through the vertical rod part, the front end of the force measuring rod is provided with a force measuring sensor 544, and a force measuring return spring 545 is sleeved on the force measuring rod, the two ends of the force measuring return spring are respectively connected to the front side of the vertical rod part and the rear side of the force measuring sensor. When the steel ball cannot enter the window, the bridge connecting rod continues to advance according to the set process along with the moving seat. At this time, the push plate, push rod, steel ball, and force measuring rod are all blocked by the window and no longer pushed, thus causing the continuing to advance upright part to separate from the push plate and compress the force measuring return spring. When the force sensor senses that the pressure of the force measuring return spring is gradually increasing, it feeds back the value to the main controller to report an error. At the same time, the main controller obtains accurate data on the non-compliance of the cage in the window. Once the set upper limit force is reached, the push moving part will automatically retract. Compared with the uncontrollable force of manual force, this application can accurately set the push force of the steel ball to enter the window, thereby achieving standardization. When the push moving part retracts along the first guide rail, the force measuring return spring acts as a reset component to bring the push plate and push rod closer to the upright part for reset. In use, a force measuring rod is set on the upper part of the upright instead of a spring directly on the push rod. The purpose is to have two rods running parallel through the upright and connected to the push plate. When the push rod moves back and forth relative to the upright, the two rods restrain each other, making the reciprocating movement more stable, the data more accurate, and less prone to damage or jamming, thus improving the detection efficiency.

[0057] Example 6:

[0058] The difference from the above embodiment is that the first guide rail seat 41 is provided with a lead screw base 45, and a ball screw 46 is sleeved on the lead screw base. The movable seat is fixed outside the sleeve of the ball screw. The first driving component is a servo motor 666 connected to the ball screw. This application can use the servo motor 666 to drive the ball screw, thereby driving the movable seat and the entire set of pushing and moving components to perform linear reciprocating motion. When the steel ball cannot be inserted into the window, the increased torque feedback of the servo motor 666 can also accurately determine which window of the cage is unqualified. This forms a double-insurance sensing with the force-measuring reset spring 545 and the force-measuring sensor. The detection is more accurate and efficient. Of course, this application is not limited to the first driving component being a servo motor 666; other driving elements that can achieve the technical purpose of this invention can also be applied to this invention.

[0059] Example 7:

[0060] The difference from the above embodiments lies in that this application also includes a cage window inspection machine. The inspection machine includes the aforementioned cage window inspection device, an infeed conveying device, a moving device for transporting workpieces from the infeed conveying device to a reference assembly, and an outfeed sorting device for sorting workpieces after they have passed the steel ball inspection. The cage is fed into the inspection machine via the infeed conveying device, then clamped onto the inspection device by the moving device, and subsequently clamped onto the outfeed sorting device for discharge by the moving device. All of the above devices are connected to a central controller, thereby achieving fully automatic and rapid inspection and differentiation of cage windows.

[0061] The discharge sorting device includes a discharge conveyor belt d1, a defective product pushing component d2, and a defective product collecting component d3, with the pushing component and collecting component located on opposite sides of the discharge conveyor belt. Defective products are pushed off the conveyor belt and collected by the pushing component. Qualified products continue to be conveyed out of the testing machine via the discharge conveyor belt.

[0062] The cage window inspection machine described in this application is already in use. The inspection time and efficiency of each cage are based on data and performance obtained from actual use. Therefore, the applicant urgently needs to apply for a patent for protection. The entire set of equipment was independently developed by the applicant and is the first set of equipment in China used for inspecting the defects, burrs, and dents of cage windows.

[0063] Example 8:

[0064] The difference from the above embodiments is that the testing machine of this application includes an adjuster, which includes an adjusting guide rail b11, an adjusting slider b12 disposed on the adjusting guide rail, and an adjusting screw b13 disposed between the adjusting guide rail and the adjusting slider. The outer contour of the cross-section of at least the portion of the adjusting guide rail that cooperates with the adjusting slider is dovetail-shaped. The rail groove b121 of the adjusting slider is a dovetail groove adapted to the dovetail-shaped portion of the adjusting guide rail. The adjusting screw passes between the adjusting guide rail and the adjusting slider, and a threaded hole b131 that is screwed to the adjusting screw is partially formed in the adjusting guide rail to form a bottom hole groove b131-1, and partially formed in the rail groove to form a top threaded hole groove b131-2. The inner groove wall of the bottom hole groove that cooperates with the threaded circumferential surface of the adjusting screw is a smooth arc-shaped surface. The top threaded hole groove has a thread that is screwed to the adjusting screw. The bottom hole groove and the top threaded hole groove are spliced ​​together to form a complete circular threaded hole.

[0065] In this application, the threaded hole of the adjuster that mates with the adjusting screw is formed by two parts: a smooth, unthreaded bottom groove b131-1 in the lower half and a top threaded groove b131-2 with internal threads in the upper half. A dovetail structure further limits the engagement of the bottom groove b131-1 and the top threaded groove b131-2, namely the adjusting guide and the adjusting slider, ensuring a tight and effective fit between the adjusting screw and the threaded hole. Since the bottom of the threaded hole is a smooth, unthreaded arc surface while the top is threaded, only the upper half of the threaded hole engages with the adjusting screw; the lower half only needs to press against the adjusting screw. This significantly reduces friction with the adjusting screw, allowing for a smaller thread pitch at the top and the ability to mate with a finer-threaded adjusting screw. This makes adjustment easier, and the adjuster can achieve adjustments as fine as 5 micrometers per adjustment, compared to existing adjustments that are only a few micrometers. This greatly improves adjustment accuracy and efficiency, truly achieving micrometer-level fine-tuning. This is an effect that ordinary regulators currently on the market cannot achieve. Furthermore, the regulator described in this application has been applied in actual production; the aforementioned data was obtained through practical application.

[0066] The adjuster of this application can also be applied to the height position of the bridge link in the aforementioned cage window detection device.

[0067] Example 9:

[0068] The difference from the above embodiment lies in that the axis b112 of the threaded hole formed by the bottom hole groove and the top threaded hole groove is located within the bottom hole groove. That is, the bottom hole groove occupies most of the threaded hole, while the threaded top threaded hole groove only occupies a small portion of the entire threaded hole. This allows the adjusting screw to be mostly recessed within the bottom hole groove, providing a certain degree of limitation and preventing the adjusting screw from dislodging. Enlarged limiting grooves b113 are provided at both ends of the bottom hole groove. The two ends of the adjusting screw are located within the two limiting grooves, and one end is connected to an adjusting knob b132. The two limiting grooves ensure that the movement of the adjusting slider is limited to between these two grooves. Once the adjusting slider moves into a limiting groove, the bottom hole groove corresponding to the lower half of the adjusting screw disappears, and the upper thread of the adjusting screw cannot tightly engage with the thread of the top threaded hole groove, thus preventing the adjusting slider from moving further outwards and disengaging from the adjusting guide rail. The two ends of the adjusting screw can be abutted against the corresponding groove walls of the limiting groove to prevent the screw from swinging or tilting. Furthermore, since there is almost no clearance between the adjusting screw and the threaded hole, dirt or metal shavings generated from wear during long-term threaded rotation can prevent the adjusting screw from turning, affecting accuracy. Therefore, dirt or metal shavings on the adjusting screw are pushed into the limiting groove as the adjusting slider moves, preventing them from getting tangled between the adjusting screw and the threaded hole, thus ensuring the performance of the adjuster. The front end of the adjusting screw, corresponding to the limiting groove, is suspended at the bottom, providing ample buffer space. This effectively prevents the front end from tilting upwards during rotation if the bottom is pressed against the groove while the top is suspended. This ensures the effective and efficient use of the adjusting screw, making it less prone to damage and extending its service life.

[0069] Example 10:

[0070] The difference from the above embodiment lies in that a narrow, elongated elastic reinforcing groove b123 is formed on the symmetrical center surface of the adjusting slider. This elastic reinforcing groove extends through the adjusting slider along the length of the adjusting guide rail and communicates with the top threaded slot b131-2. The blind end of the elastic reinforcing groove, away from the adjusting screw, is an enlarged arc-shaped anti-crack groove b124. A locking bolt b125 is provided on the adjusting slider perpendicular to the length of the adjusting guide rail. This locking bolt passes through the adjusting slider and the elastic reinforcing groove b123 to lock and limit the position of the adjusting slider. When the position of the adjusting slider needs to be adjusted, first loosen the locking bolt, then rotate the adjusting screw to move the adjusting slider. After adjustment, tighten the locking bolt so that the two sides of the elastic reinforcing groove come closer together, pressing the adjusting slider firmly against the adjusting screw, preventing it from moving. The above structure is convenient for adjustment and fixing, and has good overall compactness and stability.

[0071] Example 11:

[0072] The difference from the above embodiments is that the adjustment guide rail is provided with scale markings and / or model markings along its length. For ease of adjustment, this application may also provide scale markings and / or model markings as described above, thereby facilitating quick adjustment by the operator.

[0073] Example 12:

[0074] The difference from the above embodiments is that a feeding conveying device includes a feeding conveyor belt a1, a conveying guide rod a2 disposed on both sides of the feeding conveyor belt, two symmetrically arranged positioning forks a31 located in front of the feeding conveyor belt, an adjuster as described above, and an adjustment base assembly. The positioning forks are disposed on the adjuster, and the position of the positioning forks can be adjusted by adjusting the adjuster, so that the positioning forks can be adapted to the cage model being tested. The adjuster is mounted on the adjustment base assembly and can be moved back and forth along the length of the feed conveyor belt by the adjustment base assembly carrying the adjuster and the positioning fork a31. The rear end faces of the two conveying guide rods are symmetrically provided with combing guide slopes a21 that gradually approach each other from back to front, and the front end faces are symmetrically provided with discharge steps a22 for increasing the spacing. The spacing between the discharge steps of the two conveying guide rods is greater than the spacing between the middle areas of the two conveying guide rods. When the positioning fork moves into position in the direction of the feed conveyor belt, at least the projection of the fork head portion of the positioning fork onto the plane where the upper surface of the feed conveyor belt is located can overlap with the upper surface of the feed conveyor belt.

[0075] Based on the characteristic that the cage windows are concave relative to the top and bottom, this application utilizes specific conveyor guides to simultaneously transport and orient the cage. Specifically, during transport, the cage rotates along a gradually narrowing guide slope, causing the two opposing windows to engage precisely on the two opposing conveyor guides. Since the distance between the conveyor guides is less than the distance between the top or bottom edges of the two opposing windows of the cage, the cage's orientation is fixed during transport. Upon reaching the discharge step, a positioning fork is positioned at the front of the infeed conveyor belt. At this point, the edges of the corresponding two windows of the cage engage with the positioning fork for restraint. The cage is now in position, and the infeed conveyor belt stops. To facilitate upward removal of the cage, a discharge step is provided on the conveyor guides, allowing the cage to disengage from the side restraints of the conveyor guides, with only the positioning fork providing orientation restraint. This ensures the oriented cage remains consistent throughout. When upward removal is required, the positioning fork retracts and disengages from the cage, and then a lifting device removes the cage from the infeed conveyor belt for inspection.

[0076] Example 13:

[0077] The difference from the above embodiment is that the conveying guide rod is an inwardly arc-shaped comb structure, at least on the side facing the center of the feed conveyor belt. This ensures that the retainer will not get stuck during conveying and facilitates the retainer's entry into the middle section of the conveying guide rod from the combing ramp as needed. It also facilitates the retainer's entry into the discharge step section from the middle section of the conveying guide rod while maintaining its orientation, preventing deflection and ensuring stable forward movement. Photoelectric switches a6 are installed on both sides of the feed conveyor belt corresponding to the discharge step. The transmitter and receiver of the photoelectric switch a6 can be respectively located on both sides of the feed conveyor belt. When the retainer is conveyed to the discharge step and reaches its position, it blocks the photoelectric switch a6. Upon receiving the signal, the main controller stops the feed conveyor belt transmission, then the positioning fork retracts the retainer, and the retainer is then lifted upwards by the moving device and detached from the feed conveyor belt. After the retainer detaches, the photoelectric switch a6 operates normally, and the feed conveyor belt restarts to continue conveying the next retainer.

[0078] Example 14:

[0079] The difference from the above embodiment is that the feed conveyor belt is further provided with guide rod adjustment seats a4 on both sides. The guide rod adjustment seats have guide rod height adjustment uprights a41 that can be adjusted along the height direction via slots and bolts. A horizontally arranged guide rod spacing adjustment horizontal rod a42 passes through the upper end of the guide rod height adjustment upright. The conveying guide rod is located on the guide rod spacing adjustment horizontal rod. The top of the guide rod height adjustment upright has a knob handle a43 that can tighten the guide rod spacing adjustment horizontal rod a42. Because different cage models exist, to ensure the combing effect of the conveying guide rods, the spacing between the conveying guide rods needs to be adjusted accordingly before testing with different cage models, and the height of the conveying guide rods also needs to be adjusted. The above structure allows for the adjustment of the conveying guide rod spacing and their respective heights. Then, the conveying guide rods can be adjusted and positioned by tightening the corresponding bolts or knob handles.

[0080] Example 15:

[0081] The difference from the above embodiment lies in that the positioning fork has a fork groove a311 on its fork head that can mate with the window side edge of the retainer 01. The side of the fork groove closest to the center of the feed conveyor belt has an inner stop a312 extending towards the feed conveyor belt, and the side furthest from the center of the feed conveyor belt has an inclined outer locking guide a313. The front end of the inner stop extends beyond the front end of the outer locking guide a313. The aforementioned inner stop, fork groove, and outer locking guide a313 ensure stable positioning of the retainer in the required orientation. Even if a slight deviation occurs at the end of the conveying process, the retainer can be adjusted to the required orientation through the cooperation of the inner stop, fork groove, and outer locking guide a313. The fork groove is a V-shaped pointed groove, ensuring that after the positioning fork mates with the outer edge of the corresponding window furthest from the center line of the feed conveyor belt, it can only guide and confine the retainer to the standard required orientation.

[0082] Example 16:

[0083] The difference from the above embodiment is that the adjusting slider b12 and the rear end of the positioning fork a31 are adjustablely connected via a slot and bolts along the length of the feed conveyor belt. For different models of cages, the distance the positioning fork extends into the feed conveyor belt varies; the above structure allows for adjustment of the insertion distance of the positioning fork into the feed conveyor belt.

[0084] The adjusting base assembly includes a base track a51, an adjusting base a52 that slides along the base track, and a height adjusting plate a53 disposed on the adjusting base. The height adjusting plate has a slot along the direction of gravity. The adjusting guide rail b11 is height-adjustably connected to the height adjusting plate via a pad a54, the slot, and bolts. The adjusting base can move back and forth along the base track, thereby driving the reciprocating movement of the positioning fork. The adjusting guide rail is adjustablely disposed on the height adjusting plate via the slot and bolts, thus allowing for the corresponding adjustment of the height of the adjusting slider and the positioning fork disposed on the adjusting guide rail, making it suitable for different types of cages.

[0085] Example 17:

[0086] The difference from the above embodiments lies in the cage moving device described above, which includes a translation component, a lifting component, a gripping component, and a clamping component. The lifting component is mounted on the translation component, the gripping component is mounted on the lifting component, and the clamping component is mounted on the gripping component. The gripping component includes a multi-claw cylinder c1, an inner support claw c12 detachably mounted on the claw head c11 of the multi-claw cylinder, and a replaceable claw head pad c13 located between the inner support claw and the claw head. The clamping component includes several clamping guide rods c21 evenly distributed around the bottom periphery of the multi-claw cylinder and extending downwards, and a clamping member c22 located at the bottom of the clamping guide rods and extending horizontally towards the center directly below the multi-claw cylinder. The bottom of the clamping member is higher than the bottom end of the inner support claw. The translation component, lifting component, gripping component, and clamping component are all electrically connected to the main controller.

[0087] Existing multi-jaw cylinders are widely used in automated equipment due to their ability to easily grip workpieces with internal support or external clamping, especially for gripping small workpieces. For example, the cage in this application has a structure with a regular inner ring. Multi-jaw cylinders are very suitable for gripping cages with internal support. However, before use, each cylinder claw of the multi-jaw cylinder needs to be adjusted to the center position according to the size of the cage in order to grip stably. But once the cage model is changed and the inner diameter is changed, each cylinder claw also needs to be readjusted. Since all cylinder claws need to be re-centered, the adjustment is troublesome and the operation is inconvenient.

[0088] This application can employ a three-jaw or four-cylinder design. It adds an inner support claw to the cylinder jaws of the multi-jaw cylinder for direct gripping of the cage. A replaceable jaw head pad is placed between the inner support claw and the jaw head. Therefore, when the cage model needs to be changed, only the jaw head pad of different thickness needs to be replaced to adjust the position of the inner support claw, while the jaw head remains aligned. As long as the jaw head pads are of consistent thickness, the alignment of the inner support claws after replacing the pads is guaranteed, avoiding the hassle of adjusting the jaw head alignment and simplifying operation. Furthermore, a clamping element that presses against the top of the cage limits its position during gripping. Since there are multiple clamping elements, the corresponding positions on the top of the cage are confined to the same horizontal plane, ensuring that the cage's orientation remains unchanged during gripping, movement, and placement. This facilitates smooth and efficient subsequent cage inspection.

[0089] Example 18:

[0090] The difference from the above embodiment is that the top of the clamping guide rod is connected to the multi-claw cylinder through the rod seat c23 and the upper end of the clamping guide rod extends out of the rod seat. A limit washer c27 is connected to the part of the upper end of the clamping guide rod that extends out. A clamping spring c24 is sleeved on the clamping guide rod. The upper end of the clamping spring is connected to the bottom end of the rod seat and the lower end is connected to the middle or bottom end of the clamping guide rod.

[0091] When gripping the cage, the clamping springs ensure that the clamping elements at the lower ends of each clamping guide rod press against the top of the cage, guaranteeing balanced force on the top of the cage and smooth movement of the cage.

[0092] At least one proximity switch c25 is provided on the outside of the multi-claw cylinder. At least one of the multiple clamping guide rods has an anti-collision sensing plate c26 at its top end that cooperates with the proximity switch. The outer diameter of the anti-collision sensing plate is larger than the outer diameter of the limiting pad. When the retainer is placed in the testing position by the moving device, if the retainer model is incorrect or there is a mix-up, the retainer may not be able to be placed on the base of the testing center as required, resulting in one side tilting up or the bottom end being higher than the packaged workpiece. This causes the clamping guide rod to be excessively pushed upward when the retainer is placed, causing the anti-collision sensing plate to touch the proximity switch. The proximity switch is activated and sends a signal to the main controller to report an error. When the retainer is the correct specification part set for the corresponding equipment, the retainer can be placed on the reference surface of the testing center as required. At this time, the inner support claws are released, and the clamping guide rod is clamped to the retainer under the action of the clamping spring, so that the retainer and the packaged workpiece 22 on the reference surface of the testing center are smoothly and as required for positioning. The bottom end can be flat against the reference surface of the base 21, thereby realizing the smooth transfer of the retainer into place.

[0093] Example 19:

[0094] The difference from the above embodiments is that the clamping components c22 at the lower end of each clamping guide rod are interconnected on the axis of the multi-jaw cylinder to form a claw disk structure. This application has three clamping guide rods, and the corresponding claw disk structure is a three-jaw claw disk structure. The connection between the clamping components enables linkage, allowing clamping of the retainer to be performed on a single plane. Furthermore, only one set of anti-collision sensor and proximity switch is required. This results in more stable and efficient handling and clamping of the retainer.

[0095] Example 20:

[0096] The difference from the above embodiment is that the claw head c11 is provided with a claw seat c14 with a seat groove. The claw head pad c13 and the inner support claw c12 are detachably disposed in the seat groove of the claw seat. The thickness of the pad is marked on the claw head pad. The claw seat facilitates the positioning and installation of the claw head pad c13 and the inner support claw c12. The thickness value of the pad is set on the claw head pad, which can be used to accurately select different models of cages. In addition, the cage model can also be selected directly from the markings on the claw head pad.

[0097] Example 21:

[0098] The difference from the above embodiment is that the bottom of the lifting assembly is connected to a connecting plate c3 extending along the length direction to both sides of the lifting assembly. Each end of the connecting plate is provided with a set of interconnected gripping components and pressing components. This structure allows the two steps of gripping the cage to be tested from the infeed conveyor belt and sending it to the base, and gripping the tested cage from the base of the testing device and sending it to the discharge conveyor belt, to be performed simultaneously, thereby greatly improving the testing efficiency of the equipment.

[0099] Example 22:

[0100] The difference from the above embodiments lies in that the translation component includes a translation frame c41, a translation track c42 horizontally disposed on the translation frame, a translation slider c43 cooperating with the translation track, and a translation lead screw c44 parallel to the translation track and passing through the translation slider. One end of the translation lead screw is connected to a drive motor, and the translation slider is connected to the lifting component. The translation slider, carrying the lifting component, can reciprocate along the translation track via the translation lead screw. The above-mentioned translation component has a stable structure, good controllability when connected to the main controller, and high precision. Of course, the translation component of this application is not limited to the above-described translation structure; any translation component that can realize the technical description of this invention can also be applied to this application.

[0101] Example 23:

[0102] The difference from the above embodiment is that the translation slider is connected to the base plate c51 of the lifting assembly via a sleeve block c45 with a clamping groove. The clamping groove faces the base plate. The two ends of the translation screw are located on screw seats c46, and a guide plate c47 passing through the clamping groove is connected between the screw seats. The translation slider is externally embedded in the sleeve block and internally embedded in the translation track c42. Limiting guide plates c431 that can abut against the outer edge of the track groove of the translation track c42 are also provided on the upper and lower surfaces. The above structure allows the lifting assembly to be stably connected to the translation assembly and follow it. It is not easy for the movement or shaking to occur during the entire movement process, thereby improving the accuracy and efficiency of the device and reducing the failure rate.

[0103] Example 24:

[0104] The difference from the above embodiments lies in that the lifting assembly includes a base plate c51 connected to the translation assembly, a lifting seat c52 connected to the base plate c51, a lifting slider c53 disposed on the lifting seat, a lifting slide rail c54 cooperating with the lifting slider and extending beyond the lifting seat at its lower end, a connecting plate c3 connected to the lower end of the lifting slide rail for connecting the gripping assembly, and a lifting cylinder c55 disposed on the lifting seat with the lower end of the piston rod c551 connected to the connecting plate. The lifting seat has two sets of lifting sliders c53 and lifting slide rails c54, and the top ends of the two lifting slide rails are connected by an upper limit block c56. More preferably, the lifting seat has at least two sets of lifting sliders. Ordinary lifting mechanisms typically only have a single guide rod, and the upper limit block not only limits the movement of the lifting slide rail but also ensures its stability. The above design has a simple structure, stable performance, is less prone to deviation, has high accuracy during use, and is less prone to failure.

[0105] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
