Description

Technical Field

[0001] The present invention relates to the technical field of cage detection, and particularly to an adjuster, a feeding conveying device and a cage window detector. Background Art

[0002] The rolling bearings used in vehicles generally consist of four parts: an outer ring, an inner ring, rolling elements and a cage. The cage of the rolling bearing plays an important role in resisting load pressure. The cage is also called a constant velocity joint, which is circular and has a plurality of windows distributed circumferentially. As an important component in the car transmission system, its function is to transmit the power of the engine from the transmission to the drive wheels to drive the car to run at high speed. The cage partially encloses all or part of the rolling elements. Its main function is to isolate the rolling elements, and at the same time guide and hold the rolling elements in the bearing. During use, the cage has a heavy load, high transmission accuracy requirements, and is also a safety component. Therefore, in the production process, quality control is very important. There are some existing devices for detecting cages in the market, such as devices for detecting the overall dimensions, window height and width of cages, and also, for example, the cage window burr, flash and bruise detector newly developed by the applicant. Since there are many different models of cages, when the detection device changes to a new batch of cages, some mechanical components of the detection device often need to be adjusted in position.

[0003] In mechanical equipment, especially in equipment that can be used to process workpieces of different sizes and models, some adjusters are often designed to accurately and conveniently adjust the positions of the mechanical components of the equipment, so that the mechanical components of the equipment can be adjusted to positions suitable for the dimensional processing requirements of the workpieces in this batch before working. Most of the existing adjusters open a complete lead screw channel on these mechanical components, and then drive the mechanical components to perform fine adjustment along the lead screw by rotating the lead screw, or directly set the mechanical components on a guide rail for adjustment and positioning. In terms of the current adjuster technology, each adjustment can only be made in increments of ten or twenty thousandths of an inch, and it is impossible to perform finer adjustments such as micron-level fine adjustments. For workpieces or equipment with high precision requirements, it is necessary for workers to continuously and repeatedly adjust to be accurate, or they can only make do with a large error to perform operations, which often results in low equipment working efficiency, poor effects and low workpiece yield.

[0004] In addition, in order to achieve automation in the detection device, conveying components are also needed. The existing conveying equipment for workpieces is generally belt conveying. When the cage is detected, it needs to be positioned according to the position of its window. Ordinary conveyor belts only have the function of conveying during the conveying process, and do not have the function of sorting out the specific orientation of the workpieces. If workers adjust the orientation manually, on the one hand, the efficiency is low and the cost is high, and on the other hand, the safety is poor. Summary of the Invention

[0005] The object of the present invention is to solve the problems raised in the above-mentioned background technology, and to provide an adjuster, a feeding conveyor device and a cage window detector.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An adjuster includes an adjustment guide rail, an adjustment slider disposed on the adjustment guide rail, and an adjustment screw rod disposed between the adjustment guide rail and the adjustment slider. The outer contour of the cross-section of at least the part of the adjustment guide rail that cooperates with the adjustment slider is in a dovetail shape. The track groove of the adjustment slider is a dovetail groove adapted to the dovetail-shaped part of the adjustment guide rail. The adjustment screw rod passes through between the adjustment guide rail and the adjustment slider, and a threaded hole screwed with the adjustment screw rod is partly formed on the adjustment guide rail to form a bottom hole groove, and partly formed on the track groove to form a top threaded hole groove. The inner groove wall of the bottom hole groove that cooperates with the threaded peripheral surface of the adjustment screw rod is a smooth arc surface. A thread screwed with the adjustment screw rod is provided in the top threaded hole groove. The bottom hole groove and the top threaded hole groove are spliced to form a complete circular threaded hole.

[0008] Preferably, the axis line of the threaded hole formed after the bottom hole groove and the top threaded hole groove are combined is located in the bottom hole groove. The two ends of the bottom hole groove are provided with enlarged limiting accommodation grooves. The two ends of the adjustment screw rod are respectively located in the two limiting accommodation grooves, and one end is connected with an adjustment knob.

[0009] Preferably, a long and narrow elastic strengthening groove is provided on the symmetry center plane of the adjustment slider. The elastic strengthening groove penetrates the adjustment slider along the length direction of the adjustment guide rail and communicates with the top threaded hole groove. The blind end of the elastic strengthening groove away from the adjustment screw rod is an enlarged arc-shaped anti-cracking groove. A locking bolt is provided on the adjustment slider perpendicular to the length direction of the adjustment guide rail. The locking bolt penetrates the adjustment slider and the elastic strengthening groove to lock and limit the adjustment slider.

[0010] Preferably, scale marks and / or model marks are provided on the adjustment guide rail along its length direction.

[0011] A feeding and conveying device includes a feeding conveyor belt, and also includes conveying guide rods arranged 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 arranged on the adjuster, and the adjuster is arranged on the adjustment base assembly and can be driven by the adjustment base assembly to reciprocate along the length direction of the feeding conveyor belt. On the opposite surfaces of the rear ends of the two conveying guide rods, there are symmetrically arranged combing guide slopes that gradually approach from back to front, and on the opposite surfaces of the front ends, there are symmetrically arranged discharging steps for increasing the spacing. The spacing between the discharging 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 in place towards the feeding conveyor belt, at least the projection of the fork head part of the positioning forks on the plane where the upper surface of the feeding conveyor belt is located can overlap with the upper surface of the feeding conveyor belt.

[0012] Preferably, at least one side of the conveying guide rod facing the center of the feeding conveyor belt is a circular arc-shaped combing guide structure that is convex inward in an arc shape, and opposite to the discharging steps on both sides of the feeding conveyor belt, there are opposed photoelectric switches (a6).

[0013] Preferably, on both sides of the feeding conveyor belt, there are also guide rod adjusting seats. On the guide rod adjusting seats, there are guide rod height adjusting vertical rods that can be adjusted in the height direction through a slotted hole and bolts. The upper ends of the guide rod height adjusting vertical rods are provided with horizontally arranged guide rod spacing adjusting horizontal rods, and the conveying guide rods are arranged on the guide rod spacing adjusting horizontal rods. The top ends of the guide rod height adjusting vertical rods are provided with turning handles that can tighten the guide rod spacing adjusting horizontal rods.

[0014] Preferably, on the fork heads of the positioning forks, there are fork grooves that can cooperate with the side edges of the windows of the cage. On the side of the fork groove close to the center of the feeding conveyor belt, there is an inner blocking portion extending towards the feeding conveyor belt, and on the side far from the center of the feeding conveyor belt, there is an inclined outer positioning guiding portion. The positioning forks are adjustably connected to the rear ends through a slotted hole and bolts arranged along the length direction of the feeding conveyor belt. The adjustment base assembly includes a base track, an adjustment base that slides along the base track, and a height adjustment plate arranged on the adjustment base. There is a slotted hole arranged along the gravity direction on the height adjustment plate, and the adjustment guide rail is adjustably connected to the height adjustment plate in height through a cushion plate and a slotted hole.

[0015] A cage window detector includes the above-mentioned feeding and conveying device.

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

[0017] 1. The threaded hole in the adjuster of the present application that cooperates with the adjustment screw is formed by two parts, namely, the bottom hole groove located in the lower half and the top threaded hole groove located in the upper half. The parts where the threaded holes of the upper and lower parts are located, namely, the adjustment guide rail and the adjustment slider, are limited and matched through a dovetail structure, so as to ensure that the adjustment screw and the threaded hole are effectively and tightly matched. Since the bottom of the entire threaded hole is a smooth arc surface without threads and the top has threads, only the upper half of the thread is matched with the adjustment screw, and the lower half only needs to be pressed against the adjustment screw, so that the friction between the adjustment screw and the adjustment screw is greatly reduced, so that the thread pitch of the top can be arranged smaller, and can cooperate with the adjustment screw with finer threads, so that the adjustment is easier. At the same time, the adjuster of the present application can be adjusted as finely as 5 millimeters per adjustment each time, compared with the existing adjustment that can only be adjusted by more than ten or twenty millimeters, the adjustment accuracy and adjustment efficiency are greatly improved, and the micro-level fine adjustment is truly achieved. This is an effect that ordinary adjusters on the market cannot achieve. And the adjuster of the present application has been applied to actual production, and the above data is obtained through actual application.

[0018] 2. According to the characteristic that the window position of the retainer is concave relative to the top and bottom, the retainer can be combed while being transported by the above-mentioned specific conveying guide rod. Specifically, during the conveying process, the retainer is combed and rotated by the gradually narrowing combing guide slope, so that the two relative windows are just stuck on the two relative conveying guide rods. Since the spacing between the conveying guide rods is smaller than the spacing between the top edge or bottom edge of the two relative windows of the retainer, the orientation of the retainer is limited for conveying. When conveying to the discharge stage, the front end of the feed conveyor belt is waiting for a positioning fork. At this time, the edges of the corresponding two window sides of the retainer are stuck in the positioning fork for limiting. At this time, the retainer has been transported to the position, and the feed conveyor belt stops. In order to facilitate the upward removal of the retainer, the discharge stage is opened on the conveying guide rod so that the retainer is separated from the two side limits of the conveying guide rod, and the orientation is limited only by the positioning fork, thereby ensuring that the combed retainer always maintains one orientation. When it is necessary to take it out upward, the positioning fork retreats and disengages from the retainer, and then the retainer is taken out from the feed conveyor belt by the moving device and sent for inspection.

Detailed implementation manners

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0047] The present invention will be further described below in conjunction with the accompanying drawings:

[0048] Embodiment 1:

[0049] 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 provided 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 provided on the first guide rail seat. The pushing and moving component includes a moving seat 43 provided 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 moving seat. The steel ball is provided at the front end of the pushing rod. The moving seat is connected to the first driving component and can reciprocate along the first guide rail under the drive of the first driving component. The first driving component is electrically connected to the main controller of this device.

[0050] The cage steel ball detection device further includes a machine base 1 and a reference component 2 provided on the machine base. Multiple groups of steel ball detection assemblies are radially arranged around the reference component with the reference component as the center on the machine base, and the steel balls are arranged towards the center of the reference component.

[0051] During the use process of the cage window, it cooperates with the steel balls. If the dimensional accuracy of the window is unqualified, it will cause the cooperation between the cage window and the steel balls not to meet the technical specification requirements, affecting the later use. Existing equipment for measuring dimensions such as height and width of the cage window, although the above-mentioned dimensional inspections are qualified, the existence of burrs, flash or bruises will also cause the steel balls to be unable to be inserted. The existing solution relies on the manual ball insertion method with different forces, that is, holding a steel ball and stuffing it into the cage window to detect. It takes about 30 seconds to complete the steel ball stuffing detection for multiple windows of a cage. The manual detection method is not only inefficient but also laborious. Moreover, once the force during the forced stuffing is uneven and there is no standardization of the force to distinguish defective products, it may also cause some defective products to be put into use, thus affecting the operation effect and service life.

[0052] In this application, a reference component can be set at the center of the machine base, and multiple groups of steel ball detection components can be arranged radially according to the number of windows on the cage 01. During detection, after placing the cage 01 on the reference component and placing it horizontally as required, when the steel ball detection component is started, that is, the first driving component is started to drive the pushing and moving component to move along the first guide rail component, so that the steel balls at the front end of the push rod move towards the corresponding cage windows and extend into them for detection. Once the steel balls cannot be pushed into the windows, information can be fed back to the main controller, and then multiple groups of steel ball detection components retract, thus completing the detection of this window. Each window corresponds to a group of steel ball detection components, so each window can be detected simultaneously. The detection of a workpiece only takes five to six seconds from placement to completion of detection, greatly improving the detection efficiency, and it can accurately detect which window is unqualified, feed back to the main controller, and the main controller controls the next discharging and sorting device to perform sorting and collection.

[0053] Embodiment 2:

[0054] The difference from the above embodiment is that the reference component includes a base 21 and a workpiece sleeve 22 detachably arranged on the base. During installation, the outer diameter of the workpiece sleeve is suitably sleeved and connected with the inner ring of the bottom opening of the cage. The base can be fixed at the center of the machine base without disassembly, while the workpiece sleeve can be easily and quickly replaced and adapted according to different models of the cage, that is, different inner diameters of the bottom opening. Similarly, the steel balls can also be replaced according to different models of the cage, so that this device can be adapted to various models of cages. Generally, the workpiece sleeve is replaced when detecting different models of cages in different batches.

[0055] Embodiment 3:

[0056] The difference from the above embodiment is that a bridging component is provided on the top of the moving seat. The bridging component includes a bridging base 51, an up-and-down adjusting guide rail 52 and an adjuster b1 arranged on the bridging base, and a bridging rod 54 connected to the front ends of the up-and-down adjusting guide rail and the adjuster. The push rod is arranged at the front end of the bridging rod.

[0057] The bridging rod and the up-and-down adjusting guide rail are detachably connected through an up-and-down adjusting slider 55 and a model spacer 56, so as to adjust the distance between the steel balls at the front end of the bridging rod and the moving seat by replacing model spacers with different thicknesses. By replacing the model spacers, the reciprocating position adjustment during steel ball detection for different models of cages can be realized, so that there is no need to adjust the reciprocating process range of the pushing and moving component relative to the first guide rail. For example, when changing from detecting the previous batch of cages with a larger inner diameter to detecting the next batch of cages with a smaller inner diameter, a thicker model spacer can be replaced to ensure the insertion amount of the steel balls into the windows, ensuring accurate and effective detection. Through the reasonable layout of the above structure, the equipment is more accurate, compact in structure, and convenient for adjustment.

[0058] Embodiment 4:

[0059] The difference from the above embodiments lies in that the adjuster includes an adjustment guide rail b11 and an adjustment slider b12 arranged on the adjustment guide rail. The adjustment guide rail of the adjuster arranged on the bridging base is parallel to the up-and-down adjustment guide rail. When changing the batch of the cage, the position of the adjustment slider on the adjustment guide rail can be used to drive the bridging link to adjust up and down to reach the reference position required for the cage of the next batch. The adjustment slider is connected to the bridging link through a side link 57, and the side link and the adjustment slider are adjustably connected through a slotted hole whose length direction is parallel to the axial direction of the ejector rod. Through the setting of this slotted hole, it is ensured that when changing the type of spacer block, that is, when the bridging link is adjusted back and forth, the connection with the side link can also be adjusted, ensuring that the adjuster can effectively drive the bridging link to adjust and perform reference positioning on it.

[0060] Through the setting of the above adjuster, when changing the batch of the cages to be detected, the bridging link connected to the ejector rod can not only be adjusted in the front and back reference positions, but also in the up-and-down reference positions, thus ensuring the applicability to cages of different models.

[0061] Embodiment 5:

[0062] 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 portion 541. A pushing base plate 542 is provided at the rear side of the vertical rod portion. The pushing rod passes through the vertical rod portion and is connected to the pushing base plate. A force measuring rod 543 is further provided on the pushing base plate. The force measuring rod is arranged in parallel with the pushing rod and also passes through the vertical rod portion. A force measuring sensor 544 is provided at the front end of the force measuring rod. 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 portion and the rear side portion of the force measuring sensor. When the steel ball cannot enter the window, the bridge connecting rod continues to advance forward according to the set process along with the moving seat. At this time, when the pushing base plate, the pushing rod, the steel ball, and the force measuring rod are all blocked by the window and no longer pushed forward, the vertical rod portion that continues to advance is separated from the pushing base plate, compressing the force measuring return spring. When the force measuring sensor senses that the pressure of the force measuring return spring gradually increases and feeds this value back to the main controller for error reporting, at the same time, the main controller obtains the inaccurate precise data of the cage at this window. Once the set upper limit force is reached, the pushing moving component will automatically retract. Compared with the uncontrollable manual force which is sometimes large and sometimes small, the present application can accurately set the magnitude of the pushing force for inserting the steel ball into the window, thus achieving standardization. When the pushing moving component retracts along the first guide rail, the force measuring return spring serves as a reset component to move the pushing base plate and the pushing rod closer to the vertical rod portion for resetting. During use, another force measuring rod is provided at the upper part of the vertical rod portion instead of directly arranging a spring on the pushing rod, so that two rods are parallelly arranged through the vertical rod portion and then connected to the pushing base plate. Thus, when the pushing rod reciprocates relative to the vertical rod portion, the two rods restrain each other, and the reciprocating movement is more stable, the data is more accurate, and it is not easily damaged or stuck, improving the detection efficiency.

[0063] Embodiment Six:

[0064] The difference from the above embodiment is that a lead screw base 45 is provided on the first guide rail base 41. A ball screw 46 is sleeved on the lead screw base. The moving seat is fixedly arranged outside the sleeve of the ball screw. The first driving component is a servo motor 666 connected to the ball screw. The present application can drive the ball screw through the servo motor 666, thereby driving the moving seat and the entire set of pushing moving components to perform linear reciprocating motion. When the steel ball cannot extend into the window, the increased torque feedback of the servo motor 666 is fed back to the main controller, and it can also accurately judge which window of the cage is unqualified. In this way, it forms a double-insurance induction with the above-mentioned force measuring return spring 545 and the force measuring sensor. The detection is more accurate and efficient. Of course, the present application is not limited to the first driving component being the servo motor 666, and other driving elements that can achieve the technical purpose of the present invention can also be applied to the present invention.

[0065] Embodiment Seven:

[0066] The difference from the above embodiments is that this application further includes a cage window detector, which includes the above-mentioned cage window detection device, a feeding conveyor device, a handling device for transporting the workpiece from the feeding conveyor device to the reference component, and a discharging and sorting device for discharging and sorting the workpiece after passing the steel ball detection. The cage is transported into the detector through the feeding conveyor device, and then the cage is clamped onto the detection device by the handling device. After that, the detected cage is also clamped onto the discharging and sorting device by the handling device for discharging. The above-mentioned devices are all connected to the main controller, so as to realize the full-automatic and rapid detection and differentiation of the cage window.

[0067] The discharging and sorting device includes a discharging conveyor belt d1, a defective product pushing component d2, and a defective product collecting component d3. The defective product pushing component and the defective product collecting component are respectively located on both sides of the discharging conveyor belt. Unqualified defective products will be pushed out of the discharging conveyor belt by the defective product pushing component for collection. Qualified cages will continue to be sent out of the detector through the discharging conveyor belt.

[0068] The cage window detector of this application is already an equipment in use. As shown in the appendix Figures 19 - 25 , the time taken for detecting a cage and the detection efficiency are both data and performances obtained from the actual use process. Therefore, the applicant urgently needs to apply for a patent for protection as soon as possible. The whole set of equipment is independently developed by the applicant and is also the first set of equipment in the country for detecting the burrs, flash, and bruises of the cage window.

[0069] Embodiment Eight:

[0070] The difference from the above embodiments is that the detector of this application includes an adjuster, which includes an adjustment guide rail b11, an adjustment slider b12 provided on the adjustment guide rail, and an adjustment screw rod b13 provided between the adjustment guide rail and the adjustment slider. The outer contour of the cross-section of at least the part of the adjustment guide rail that cooperates with the adjustment slider is in a dovetail shape. The rail groove b121 of the adjustment slider is a dovetail groove adapted to the dovetail-shaped part of the adjustment guide rail. The adjustment screw rod is arranged between the adjustment guide rail and the adjustment slider, and a threaded hole b131 screwed with the adjustment screw rod is partially opened on the adjustment guide rail to form a bottom hole groove b131-1 and partially opened on 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 peripheral surface of the adjustment screw rod is a smooth arc surface. A thread screwed with the adjustment screw rod is provided in the top threaded hole groove. The bottom hole groove and the top threaded hole groove are spliced to form a complete circular threaded hole.

[0071] The threaded hole in the adjuster of the present application that cooperates with the adjusting screw rod is formed by the clamping and cooperation of two components, namely, the smooth and threadless bottom hole groove b131-1 located in the lower half and the top threaded hole groove b131-2 with internal threads located in the upper half. The components where the bottom hole groove b131-1 and the top threaded hole groove b131-2 are located, namely the adjusting guide rail and the adjusting slider, are limited and cooperated through a dovetail-shaped structure, so as to ensure the effective and tight cooperation between the adjusting screw rod and the threaded hole. Since the bottom of the entire threaded hole is a smooth arc surface without threads while the top has threads, there is only upper-half thread cooperation with the adjusting screw rod, and only the lower half needs to abut against the adjusting screw rod. Therefore, the friction with the adjusting screw rod is greatly reduced, the thread pitch at the top can be arranged smaller, and an adjusting screw rod with finer threads can be matched. Thus, while the adjustment is easier, each adjustment of the adjuster of the present application can be as fine as 5 microns. Compared with the existing adjustment that can only be adjusted by ten or twenty silk, the adjustment accuracy and adjustment efficiency are greatly improved, and true micron-level fine adjustment is achieved. This is an effect that cannot be achieved by ordinary adjusters on the market at present. And the adjuster of the present application has been applied to actual production, and the above data is obtained through actual application.

[0072] The adjuster of the present application can also be applied to the height position of the bridge connecting rod in the above-mentioned cage window detection device.

[0073] Embodiment Nine:

[0074] The difference from the above embodiment is that the axis line b112 of the threaded hole formed by the bottom hole groove and the top threaded hole groove is located in 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 part of the entire threaded hole, so that most of the adjustment screw rod is sunk in the bottom hole groove and has a certain limiting effect, which prevents the adjustment screw rod from being disengaged to a certain extent. The two ends of the bottom hole groove are provided with enlarged limiting grooves b113, and the two ends of the adjustment screw rod are respectively located in the two limiting grooves, and one end is connected to an adjustment knob b132. The setting of the two limiting grooves allows the adjustment slider to move only between the two limiting grooves, that is, once the adjustment slider moves to the limiting groove, the bottom hole groove corresponding to the lower half of the adjustment screw rod disappears, and the upper half of the thread of the adjustment screw rod cannot be tightly engaged with the thread of the top threaded hole groove, so that the adjustment slider cannot be driven to move to the outer end to disengage from the adjustment guide rail. The two ends of the adjusting screw rod can be pressed against the corresponding groove wall of the limit groove to prevent the screw rod from swinging or tilting. In addition, since there is no gap between the adjusting screw rod and the threaded hole, once there is dirt or iron filings are produced by the wear of the long-term threaded matching and rotation, the adjusting screw rod will not be able to be turned, affecting the accuracy. Therefore, when there is dirt such as iron filings on the adjusting screw rod, it can be pushed into the limit groove when the adjustment slider moves and will not be entangled between the adjusting screw rod and the threaded hole, thereby ensuring the performance of the adjuster. Since the front end of the adjusting screw rod corresponds to the position of the limit groove, that is, the bottom of the front end is suspended, there is a sufficient buffer space, which effectively prevents the front end of the adjusting screw rod from tilting upward during the rotation process when the bottom is pressed tightly and the top is suspended. Ensure that the adjusting screw rod is used effectively and efficiently, is not easy to be damaged, and has a long service life.

[0075] Embodiment ten:

[0076] The difference from the above embodiment is that a narrow elastic enhancement groove b123 is provided on the symmetrical center plane of the adjustment slider, the elastic enhancement groove penetrates the adjustment slider along the length direction of the adjustment rail and communicates with the top threaded hole groove b131-2, the blind end of the elastic enhancement groove away from the adjustment screw is an enlarged arc-shaped anti-crack groove b124, and a locking bolt b125 is provided on the adjustment slider perpendicular to the length direction of the adjustment rail. The locking bolt penetrates the adjustment slider and the elastic enhancement groove b123 and is used to lock and limit the adjustment slider. When the position of the adjustment slider needs to be adjusted, the locking bolt is first loosened, and then the adjustment screw is rotated to move the adjustment slider. After it is adjusted to the right position, the locking bolt is tightened again so that the two side walls of the elastic enhancement groove are close to each other to tighten the adjustment slider against the adjustment screw and cannot move. The above structure is easy to adjust and fix, and has good overall compactness and stability.

[0077] Embodiment eleven:

[0078] The difference from the above embodiments lies in that scale markings and / or model markings are provided on the adjustment guide rail along its length direction. For the convenience of adjustment, the present application can also be provided with scale markings and / or model markings as described above, so as to facilitate the operator to quickly adjust to the proper position.

[0079] Embodiment Twelve:

[0080] The difference from the above embodiments lies in a feeding and conveying device, which includes a feeding conveyor belt a1, and also includes conveying guide rods a2 arranged on both sides of the feeding conveyor belt, two symmetrically arranged positioning forks a31 located in front of the feeding conveyor belt, the above-mentioned adjuster, and an adjustment base assembly. The positioning forks are arranged on the adjuster, and the position of the positioning forks can be adjusted by adjusting the adjuster, so that the positioning forks can adapt to the model of the cage to be detected. The adjuster is arranged on the adjustment base assembly and can be driven by the adjustment base assembly to move the adjuster and the positioning forks a31 reciprocally along the length direction of the feeding conveyor belt. Symmetrically arranged combing guide slopes a21 that gradually approach from the rear to the front are symmetrically opened on the opposite surfaces of the rear ends of the two conveying guide rods, and symmetrically arranged discharging steps a22 for increasing the spacing are symmetrically opened on the opposite surfaces of the front ends. The spacing between the discharging 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 in place towards the feeding conveyor belt, at least the projection of the fork head part of the positioning forks on the plane where the upper surface of the feeding conveyor belt is located can overlap with the upper surface of the feeding conveyor belt.

[0081] According to the characteristics that the positions of the cage windows are concave relative to the top and bottom, the present application can comb the orientation of the cage while conveying it through the above-mentioned specific conveying guide rods. Specifically, during the conveying process, the cage is combed and rotated by the gradually narrowing combing guide slopes, so that the two opposite windows are just stuck on the two opposite conveying guide rods. Since the spacing between the conveying guide rods is smaller than the spacing between the top edges or bottom edges of the two opposite windows of the cage, the orientation of the cage is limited for conveying. When it is conveyed to the discharging step, since there are positioning forks waiting at the front end of the feeding conveyor belt, at this time, the edges of the corresponding two windows of the cage are stuck into the positioning forks for limiting. At this time, the cage has been conveyed in place, and the feeding conveyor belt stops. In order to facilitate the upward removal of the cage, discharging steps are provided on the conveying guide rods so that the cage is disengaged from the side limits of the conveying guide rods, and only the positioning forks are used for orientation limitation, so as to ensure that the combed cage always maintains one orientation. When it needs to be removed upward, the positioning forks retract and disengage from the cage, and then the cage is removed from the feeding conveyor belt by a handling device and sent for detection.

[0082] Embodiment Thirteen:

[0083] The difference from the above embodiment is that the conveying guide rod is an arc-shaped combing guide structure with an inward arc protrusion on at least one side toward the center of the feed conveyor belt, so as to ensure that the retainer will not get stuck during the conveying process, and it is also convenient for the retainer to adjust the direction from the combing guide slope as required to enter the middle section of the conveying guide rod. It is also convenient for the retainer to enter the discharge stage section from the middle section of the conveying guide rod while maintaining its position, and it is not easy to deflect, so as to ensure its stable position forward. Opposing photoelectric switches a6 are provided at the positions corresponding to the discharge stage on both sides of the feed conveyor belt. The transmitter and receiver of the opposing photoelectric switch a6 can be respectively arranged on both sides of the feed conveyor belt. When the retainer is transported to the discharge stage position and in place, the opposing photoelectric switch a6 is just blocked. After receiving the signal, the main controller stops the feed conveyor belt transmission, and then the positioning fork withdraws the retainer, and the retainer is then extracted upward by the moving device to separate from the feed conveyor belt. After the retainer is separated, the opposing photoelectric switch a6 works normally, and the feed conveyor belt starts to continue to transmit and transport the next retainer.

[0084] Embodiment 14:

[0085] The difference from the above embodiment is that guide rod adjustment seats a4 are also provided on both sides of the feed conveyor belt, and guide rod height adjustment vertical rods a41 that can be adjusted along the height direction are provided on the guide rod adjustment seats through a slot and a bolt, and a horizontal guide rod spacing adjustment horizontal rod a42 is penetrated on the upper end of the guide rod height adjustment vertical rod, and the conveying guide rod is arranged on the guide rod spacing adjustment horizontal rod, and a knob handle a43 that can tighten the guide rod spacing adjustment horizontal rod a42 is provided on the top of the guide rod height adjustment vertical rod. Due to the different models of the retaining frame, in order to ensure the combing effect of the conveying guide rod, before changing the different models of retaining frames for testing, the spacing between the conveying guide rods also needs to be adjusted accordingly, and the height of the conveying guide rods also needs to be adjusted. The above structure can realize the adjustment of the conveying guide rod spacing and the respective heights, and then the conveying guide rods can be adjusted and positioned by tightening the corresponding bolts or knob handles.

[0086] Embodiment 15:

[0087] The difference from the above embodiment is that a fork groove a311 which can cooperate with the side edge of the window of the cage 01 is provided on the fork head of the positioning fork. An inner blocking portion a312 extending towards the feeding conveyor belt is provided on one side of the fork groove close to the center of the feeding conveyor belt, and an inclined outer positioning guide portion a313 is provided on the side away from the center of the feeding conveyor belt. The front end of the inner blocking portion extends beyond the front end of the outer positioning guide portion a313. Through the above settings of the inner blocking portion, the fork groove and the outer positioning guide portion a313, the cage is ensured to be stably positioned in the required orientation. Even if there is a small deviation at the end of the conveying, the cage can be adjusted to the required orientation through the cooperation of the above inner blocking portion, the fork groove and the outer positioning guide portion a313. The fork groove is a V-shaped pointed groove, so that after the positioning fork cooperates with the outer edge of the corresponding window away from the center line of the feeding conveyor belt, the cage can only be guided and limited to the standard required orientation.

[0088] Embodiment XVI:

[0089] The difference from the above embodiment is that the adjusting slider b12 and the rear end of the positioning fork a31 are adjustably connected by a slotted hole and a bolt arranged along the length direction of the feeding conveyor belt. For cages of different models, the distance that the positioning fork extends above the feeding conveyor belt is different. Through the above structure, the extension distance of the positioning fork extending forward into the feeding conveyor belt can be adjusted.

[0090] The adjusting base assembly includes a base track a51, an adjusting base a52 sliding along the base track, and a height adjusting plate a53 provided on the adjusting base. A slotted hole is provided on the height adjusting plate along the direction of gravity. The adjusting guide rail b11 is adjustably connected to the height adjusting plate through a cushion plate a54, the slotted hole and a bolt. The adjusting base can move back and forth along the base track, thereby driving the reciprocating movement of the positioning fork. And the adjusting guide rail is adjustably arranged on the height adjusting plate through the slotted hole and the bolt, so that the height of the adjusting slider and the positioning fork arranged on the adjusting guide rail can be adjusted accordingly, so as to be applicable to cages of different models.

[0091] Embodiment XVII:

[0092] The difference from the above embodiments lies in a kind of cage handling device as described above, which includes a translation component, a lifting component, a grasping component and a pressing component. The lifting component is arranged on the translation component, the grasping component is arranged on the lifting component, the pressing component is arranged on the grasping component. The grasping component includes a multi-jaw cylinder c1, an inner support jaw c12 detachably arranged on the jaw head c11 of the multi-jaw cylinder, and a replaceable jaw head cushion plate c13 arranged between the inner support jaw and the jaw head. The pressing component includes a plurality of pressing guide rods c21 evenly distributed along the circumferential edge of the bottom of the multi-jaw cylinder and extending downward, and a pressing member c22 arranged at the bottom of the pressing guide rod and horizontally extending toward the center directly below the multi-jaw cylinder. The height of the bottom of the pressing member is higher than the bottom end of the inner support jaw. The translation component, the lifting component, the grasping component and the pressing component are all electrically connected to the main controller.

[0093] Existing multi-jaw cylinders are widely used in automated equipment for their effect of conveniently grasping workpieces by inner support or outer clamping, especially for grasping small workpieces. For example, the cage in this application is a structure with a regular inner ring, and the multi-jaw cylinder is very suitable for inner support grasping of the cage. However, before use, each cylinder jaw of the multi-jaw cylinder needs to be adjusted to the centering position according to the size of the cage to stably grasp it. But once the cage model is changed and the inner diameter size changes, each cylinder jaw needs to be adjusted again. Since all cylinder jaws need to be re-centered, the adjustment is troublesome and the operation is inconvenient.

[0094] This application can use a three-jaw or four-cylinder. In this application, an inner support jaw for directly inner support grasping the cage is further arranged on the jaw head of the multi-jaw cylinder, that is, the cylinder jaw, and a replaceable jaw head cushion plate is arranged between the inner support jaw and the jaw head. Thus, when the equipment needs to change the cage model, only the jaw head cushion plate with different thicknesses needs to be replaced to adjust the position of the inner support jaw, while the jaw head always remains centered. As long as the thicknesses of the selected jaw head cushion plates are the same, it can be ensured that the inner support jaws are also centered after replacing the jaw head cushion plate, avoiding the trouble of adjusting the centering of the jaw head and making the operation convenient. And the pressing member that can press on the top of the cage limits the top of the cage during grasping, and since there are multiple pressing members, the corresponding positions at the top of the cage are limited on the same horizontal plane, so as to ensure that the orientation of the cage remains unchanged during the process of being grasped, moved in place and placed, thus facilitating the smooth and efficient progress of the next step of cage detection.

[0095] Embodiment XVIII:

[0096] 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 passes through the rod seat, and a limiting gasket c27 is connected to the protruding part of the upper end of the clamping guide rod. A clamping spring c24 is sleeved on the clamping guide rod, and 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.

[0097] When grabbing the retainer, the compression spring allows the compression pieces at the lower ends of the compression guide rods to be pressed on the top of the retainer, ensuring that the force on the top of the retainer is balanced and the retainer is moved smoothly.

[0098] At least one proximity switch c25 is provided on the outer side of the multi-claw cylinder, and at least one of the plurality of clamping guide rods is provided with an anti-collision sensor sheet c26 cooperating with the proximity switch at the top end, and the outer diameter of the anti-collision sensor sheet is larger than the outer diameter of the limit gasket. When the holder is placed in the position to be detected by the moving device, if the holder model is wrong or mixed, the holder may not be placed on the base of the detection center as required, and one side is tilted or the bottom is higher than the set workpiece, which causes the clamping guide rod to be excessively lifted upward when the holder is placed, so that the anti-collision sensor sheet touches the proximity switch, and the proximity switch starts to send a signal to the main controller to report an error. When the holder is a correct specification part set for the corresponding equipment, the holder can be placed on the reference surface of the detection center as required, at this time the inner support claw is loosened, and the clamping guide rod is pressed against the holder under the action of the clamping spring, so that the holder and the set workpiece 22 on the reference surface of the detection center are smoothly connected and positioned as required, and the bottom can be flatly against the reference surface of the base 21, so that the holder can be smoothly moved to the position.

[0099] Embodiment 19:

[0100] The difference from the above embodiment is that the clamping parts c22 at the lower end of each clamping guide rod are connected to each other on the axis of the multi-claw cylinder to form a claw plate structure. The present application has three clamping guide rods, and the corresponding claw plate structure is a three-claw claw plate structure. The connection between the clamping parts is realized so that the clamping can be performed on a plane when the clamping holder is clamped, and only one set of anti-collision sensor sheet and proximity switch is required. The handling and clamping of the holder is more stable and efficient.
