Description

Technical Field

[0001] The present invention relates to the technical field of cage detection, and particularly relates to a cage window detection device and a detection machine. Background Art

[0002] The bearing cage is a component on the bearing. The cage is circular ring-shaped, and is provided with a plurality of through holes (i.e., cage windows) that are distributed circumferentially along the cage and penetrate the cage radially for installing rolling elements of the bearing. The cage is also called a constant velocity joint cage. 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 travel at high speed. There are many types of constant velocity joints used in cars, among which the most widely used are the ball cage constant velocity joint and the tripod constant velocity joint. It mainly consists of a sliding sleeve, a tripod shaft, a drive shaft, a star-shaped sleeve, a cage, and a bell housing. Since the constant velocity joint transmits heavy driving torque, is subject to heavy loads, has high transmission accuracy, and has a large demand, and is also a safety component, its product quality control is very crucial during the production process.

[0003] The cage window cooperates with the steel ball. The window is completed by a precision machining method of grinding, and has high precision requirements. If the dimensional accuracy of the window is unqualified, it will cause the cooperation between the cage window and the steel ball not to meet the technical specification requirements, be prone to wear, shorten the service life of the cage, and cause abnormal noise. There are existing devices for measuring dimensions such as the height and width of the cage window, but there is currently no automated device for detecting burrs, flash or bruises on the window. The existence of burrs, flash or bruises will also cause the steel ball to be unable to be inserted. The existing solution relies on manual labor. By holding a steel ball and inserting it into the cage window to detect, it is necessary to manually insert and pull out the steel ball one by one into each window. It takes about 30 seconds to complete the steel ball insertion detection for one cage. If there is a window that cannot be inserted due to burrs, flash or bruises, it will take even longer. The manual detection method is not only inefficient but also laborious. In addition, the manually perceived force is different. Some windows may be inserted with a greater force, while they cannot be inserted with a smaller force. There is no qualitative rule and no standardization of force to distinguish defective products, which may also cause some defective products to be put into use, thus affecting the operation effect and service life. Therefore, it is very necessary to design a device for automatically and efficiently detecting burrs, flash and bruises on the window with a force standard. Summary of the Invention

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. 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.

[0049] The present invention will be further described below in conjunction with the accompanying drawings:

[0050] Embodiment 1:

[0051] A cage window detection device includes a steel ball detection component. The steel ball detection component 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 push rod 44 connected to the front end of the moving seat. The steel ball is provided at the front end of the push 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.

[0052] 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 components are radially arranged around the reference component on the machine base with the reference component as the center, and the steel balls are arranged towards the center of the reference component.

[0053] 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 radially arranged corresponding to the number of windows on the cage 01. During detection, after the cage 01 is placed on the reference component and placed horizontally as required, 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 ball at the front end of the push rod moves towards the corresponding cage window and extends into it for detection. Once the steel ball cannot be pushed into the window, 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. Moreover, 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 for sorting and collection.

[0054] Embodiment 2:

[0055] The difference from the above embodiments lies in that the reference component includes a base 21 and a sleeve workpiece 22 detachably provided on the base. During installation, the outer diameter of the sleeve workpiece is properly fitted 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 sleeve workpiece 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 the device can be adapted to various models of cages. Generally, the sleeve workpiece is replaced when detecting different models of cages in different batches.

[0056] Embodiment Three:

[0057] The difference from the above embodiments lies in 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 adjustment guide rail 52 and an adjuster b1 provided on the bridging base, and a bridging rod 54 connected to the front ends of the up-and-down adjustment guide rail and the adjuster. The top push rod is provided at the front end of the bridging rod.

[0058] The bridging rod and the up-and-down adjustment guide rail are detachably connected through an up-and-down adjustment slider 55 and a model spacer 56, so as to adjust the distance from the steel ball at the front end of the bridging rod to the moving seat by replacing model spacers with different thicknesses. By replacing the model spacer, the reciprocating position adjustment can be realized for the steel ball detection of different models of cages, so that there is no need to adjust the reciprocating process range of the top push moving part relative to the first guide rail. For example, when changing from the previous batch of cages with a larger inner diameter to the next batch of cages with a smaller inner diameter for detection, a thicker model spacer can be replaced to ensure the insertion amount of the steel ball into the window, 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.

[0059] Embodiment Four:

[0060] The difference from the above embodiments lies in that the adjuster includes an adjustment guide rail b11 and an adjustment slider b12 provided on the adjustment guide rail. The adjustment guide rail of the adjuster provided on the bridging base is parallel to the up-and-down adjustment guide rail. When changing batches of cages, the position of the adjustment slider on the adjustment guide rail can be adjusted to drive the bridging rod to move up and down to reach the reference position required for the next batch of cages. The adjustment slider is connected to the bridging rod 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 top push rod. Through the setting of this slotted hole, it is ensured that when replacing the model spacer, that is, when the bridging rod is adjusted back and forth, the connection with the side link can also be adjusted, ensuring that the adjuster can effectively drive the bridging rod to adjust and perform reference positioning on it.

[0061] By setting the above adjuster, when changing the batch of the detected cages, the bridge connecting rod connecting the top push rod can be adjusted not only in the front and rear reference positions, but also in the up and down reference positions, so as to ensure the applicability to cages of different models.

[0062] Embodiment Five:

[0063] 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 top push base plate 542 is provided at the rear side of the vertical rod portion. The top push rod passes through the vertical rod portion and is connected to the top push base plate. A force measuring rod 543 is further provided on the top push base plate. The force measuring rod is arranged parallel to the top push 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. 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 move forward according to the set process along with the moving seat. At this time, when the top push base plate, the top push 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 move forward is separated from the top push base plate to compress the force measuring return spring. When the force measuring sensor senses that the pressure of the force measuring return spring gradually increases and feeds back this value to the total controller for error reporting, at the same time, the total controller obtains the accurate data of the non-compliance of the cage at this window. Once the set upper limit force is reached, the top push 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 top push force for inserting the steel ball into the window, so as to achieve standardization. When the top push moving component retracts along the first guide rail, the force measuring return spring serves as a reset component to move the top push base plate and the top push rod closer to the vertical rod portion for reset. During use, another force measuring rod is provided above the vertical rod portion instead of directly arranging a spring on the top push rod, so that two rods are arranged in parallel through the vertical rod portion and then connected to the top push base plate. Thus, when the top push 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 easy to be damaged or stuck, improving the detection efficiency.

[0064] Embodiment Six:

[0065] 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, and the moving seat is fixedly arranged outside the sleeve of the ball screw. The first driving component is a servo motor connected to the ball screw. In this application, the servo motor can drive the ball screw, thereby driving the moving seat and the entire set of pushing and moving components to perform linear reciprocating motion. When the steel ball cannot extend into the window, the torque feedback of the servo motor is increased to the master 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 reset spring 545 and 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, and other driving elements that can achieve the technical purpose of the present invention can also be applied to the present invention.

[0066] Embodiment Seven:

[0067] The difference from the above embodiment is that this application further includes a cage window detection machine, which includes the above-mentioned cage window detection device, a feeding and conveying device, a handling device for transporting the workpiece from the feeding and conveying device to the reference component, and a discharging and sorting device for discharging and sorting the workpiece after passing through the steel ball detection. The cage is transported into the detection machine through the feeding and conveying device, then the cage is clamped to the detection device through the handling device, and then the detected cage is also clamped to the discharging and sorting device through the handling device for discharging. The above-mentioned devices are all connected to the master controller, so as to realize the full-automatic and rapid detection and differentiation of the cage window.

[0068] 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 part and the defective product collecting component are respectively located on both sides of the discharging conveyor belt. Unqualified defective products will be pushed out and collected from the discharging conveyor belt by the defective product pushing part. The qualified cages will continue to be sent out of the detection machine through the discharging conveyor belt.

[0069] The cage window detection machine 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 all 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 entire 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 on the windows of cages.

[0070] Embodiment Eight:

[0071] The difference from the above embodiments is that the inspection machine of the present 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 the shape of a dovetail. 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 disposed 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. After the bottom hole groove and the top threaded hole groove are spliced, a complete circular threaded hole is formed.

[0072] In mechanical equipment, especially in equipment that can be used to process workpieces of different sizes and models, adjusters for adjusting the positions of mechanical components of the equipment are often designed, so that the mechanical components of the equipment can be adjusted to positions suitable for the size processing requirements of the workpieces in this batch before working. Most of the existing adjusters are to open a complete screw rod channel on these mechanical components, and then drive the mechanical components to make fine adjustments along the screw rod by rotating the screw rod, 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 finer adjustments such as micron-level adjustments cannot be made. For workpieces or equipment with high precision requirements, it is necessary to continuously and repeatedly adjust manually to be accurate, or only make do with a large error to carry out operations, which often results in low equipment working efficiency, poor results, and low workpiece yield.

[0073] The threaded hole in the adjuster of the present application that cooperates with the adjusting screw rod is formed by the fitting 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 fitted through a dovetail-shaped structure, so as to ensure the effective and tight fit 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 thread fit in the upper half between the adjusting screw rod and the threaded hole, and only need to press tightly against the adjusting screw rod in the lower half. Therefore, the friction between the adjusting screw rod is greatly reduced, so that the thread pitch at the top can be arranged to be smaller, and the 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 the micro-adjustment at the micron level is truly 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 are obtained through actual application.

[0074] The adjuster of the present application can also be applied to the height position of the bridge connecting rod in the cage window detection device described above.

[0075] Embodiment Nine:

[0076] 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.

[0077] Embodiment ten:

[0078] 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.

[0079] Embodiment eleven:

[0080] The difference from the above embodiments lies in that scale marks and / or model marks are provided on the adjustment guide rail along its length direction. For the convenience of adjustment, the scale marks and / or model marks can also be set as described above in this application, so as to facilitate the operator to quickly adjust to the correct position.

[0081] Embodiment Twelve:

[0082] 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 be adapted 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. On the opposite surfaces of the rear ends of the two conveying guide rods, combing guide slopes a21 that gradually approach from the rear to the front are symmetrically provided, and on the opposite surfaces of the front ends, discharging steps a22 for increasing the spacing are symmetrically provided. 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 direction, at least the projection of the fork heads 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.

[0083] The existing conveying equipment for workpieces is generally belt conveying. When detecting the cage, it is necessary to position it 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 combing the specific orientation of the workpieces. If manually adjusting the orientation, on the one hand, the efficiency is low and the cost is high, and on the other hand, the safety is also poor.

[0084] According to the characteristic that the window positions of the cage are concave relative to the top and bottom, the above-mentioned specific conveying guide rods can comb the orientation of the cage while conveying it. Specifically, during the conveying process, the cage is combed and rotated by the gradually narrowing combing guide slope, so that the two opposite windows are exactly stuck on the two opposite conveying guide rods. Since the distance between the conveying guide rods is smaller than the distance 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 discharge step, since there is a positioning fork waiting at the front end of the feeding conveyor belt, the edges of the corresponding two window sides of the cage are caught in the positioning fork 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, a discharge step is provided on the conveying guide rod so that the cage is disengaged from the side limits of the conveying guide rod and is only limited in orientation by the positioning fork, thus ensuring that the combed cage always maintains one orientation. When it needs to be removed upward, the positioning fork retracts and disengages from the cage, and then the cage is removed from the feeding conveyor belt by the handling device and sent for inspection.

[0085] Embodiment Thirteen:

[0086] The difference from the above embodiment is that at least one side of the conveying guide rod facing the center of the feeding conveyor belt is a circular arc combing guide structure with an inward arc-shaped protrusion, so as to ensure that the cage will not get stuck during the conveying process, and it is also convenient for the cage to adjust the direction as required from the combing guide slope and enter the middle section of the conveying guide rod. Similarly, it is also convenient for the cage to enter the discharge step section from the middle section of the conveying guide rod while maintaining its orientation, and it is not easy to deflect, ensuring its stable orientation forward. Opposite photoelectric switches a6 are provided at the positions corresponding to the discharge step on both sides of the feeding conveyor belt. The transmitter and receiver of the opposite photoelectric switch a6 can be respectively arranged on both sides of the feeding conveyor belt. When the cage is conveyed to the discharge step position and in place, it just blocks the opposite photoelectric switch a6. After the total controller receives the signal, it stops the transmission of the feeding conveyor belt, then the positioning fork withdraws from the cage, and the cage is then lifted upward by the handling device and disengaged from the feeding conveyor belt. After the cage is disengaged, the opposite photoelectric switch a6 works normally, and the feeding conveyor belt starts to continue to convey the next cage.

[0087] Embodiment Fourteen:

[0088] The difference from the above embodiments is that guide rod adjustment seats a4 are further provided on both sides of the feeding conveyor belt. On the guide rod adjustment seats, there are guide rod height adjustment vertical rods a41 that can be adjusted in the height direction through a slotted hole and bolts. The upper end of the guide rod height adjustment vertical rod is provided with a horizontally arranged guide rod spacing adjustment horizontal rod a42. The conveying guide rods are arranged on the guide rod spacing adjustment horizontal rod. The top of the guide rod height adjustment vertical rod is provided with a knob a43 that can tighten the guide rod spacing adjustment horizontal rod a42. Due to different models of the cage, in order to ensure the combing effect of the conveying guide rods, before detecting with different models of cages, the spacing between the conveying guide rods needs to be adjusted accordingly, and the height of the conveying guide rods also needs to be adjusted. The adjustment of the spacing and the respective heights of the conveying guide rods can be achieved through the above structure, and then the conveying guide rods can be adjusted and positioned by tightening the corresponding bolts or knobs.

[0089] Embodiment Fifteen:

[0090] The difference from the above embodiments is that a fork groove a311 that can cooperate with the side edge of the window of the cage 01 is provided on the fork head of the positioning fork. On one side of the fork groove close to the center of the feeding conveyor belt, there is an inner blocking portion a312 extending towards the feeding conveyor belt, and on the side far from the center of the feeding conveyor belt, there is an inclined outer clamping position guiding portion a313. The front end of the inner blocking portion extends beyond the front end of the outer clamping position guiding portion a313. Through the above settings of the inner blocking portion, fork groove and outer clamping position guiding portion, it is ensured that the cage is 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, fork groove and outer clamping position guiding portion. The fork groove is a V-shaped pointed groove, so that after the positioning fork cooperates with the outer edge of the corresponding window far from the center line of the feeding conveyor belt, the cage can only be guided and limited to the standard required orientation.

[0091] Embodiment Sixteen:

[0092] The difference from the above embodiments is that the adjustment slider b12 and the rear end of the positioning fork a31 are adjustably connected through a slotted hole and bolts arranged along the length direction of the feeding conveyor belt. For different models of cages, the distance that the positioning fork extends above the feeding conveyor belt is different. Through the above structure, the adjustment of the extending distance of the positioning fork extending forward into the feeding conveyor belt can be achieved.

[0093] The adjustment base assembly includes a base rail a51, an adjustment base a52 that slides along the base rail, and a height adjustment plate a53 provided on the adjustment base. A linear slot is provided on the height adjustment plate along the direction of gravity. The adjustment guide rail b11 is adjustably connected to the height adjustment plate through a backing plate a54, the linear slot, and bolts. The adjustment base can move back and forth along the base rail, thereby driving the reciprocating movement of the positioning fork. The adjustment guide rail is adjustably arranged on the height adjustment plate through the linear slot and bolts, so that the height of the adjustment slider and the positioning fork arranged on the adjustment guide rail can be adjusted accordingly, thus being applicable to cages of different models.

[0094] Embodiment XVII:

[0095] The difference from the above embodiment is that, for example, a cage handling device includes a translation assembly, a lifting assembly, a grasping assembly, and a pressing assembly. The lifting assembly is provided on the translation assembly, the grasping assembly is provided on the lifting assembly, the pressing assembly is provided on the grasping assembly. The grasping assembly includes a multi-jaw cylinder c1, an inner support jaw c12 detachably provided on the jaw head c11 of the multi-jaw cylinder, and a replaceable jaw head backing plate c13 provided between the inner support jaw and the jaw head. The pressing assembly 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 provided 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 assembly, the lifting assembly, the grasping assembly, and the pressing assembly are all electrically connected to the main controller.

[0096] Existing multi-jaw cylinders are widely used in automated equipment for their convenient effect of internally supporting or externally clamping and grasping workpieces, especially for grasping small workpieces. For example, the cage in this application has a structure with a regular inner ring, and a multi-jaw cylinder is very suitable for internally supporting and grasping 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, then 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.

[0097] The present application is to set an inner support claw for directly supporting and grasping the retainer on the claw head of the multi-claw cylinder, i.e., the cylinder claw. The multi-claw cylinder can be three-claw, four-claw, etc. The present application can select a three-claw cylinder, and set a replaceable claw head pad between the inner support claw and the claw head, so that when the equipment needs to change the retainer model, it only needs to replace the claw head pad of different thicknesses to adjust the position of the inner support claw, and the claw head always remains centered. As long as the thickness of the claw head pad is consistent, it can be ensured that the inner support claws are also centered after the claw head pad is replaced, avoiding the trouble of adjusting the centering of the claw head, and the operation is convenient. And through the clamping piece that can be pressed on the top of the retainer, the top of the retainer is limited when grasping the retainer. Since there are multiple clamping pieces, the corresponding positions of the top of the retainer are limited to the same horizontal plane, thereby ensuring that the orientation of the retainer can always remain unchanged during the process of the retainer being grasped and moved into place, so that the next step of retainer detection can be carried out smoothly and efficiently.

[0098] Embodiment 18:

[0099] 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.

[0100] 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.

[0101] 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 base 21, so that the holder can be smoothly moved to the position.

[0102] Embodiment 19:

[0103] The difference from the above embodiments is that the pressing members c22 at the lower ends of each pressing guide rod are connected to each other on the axis of the multi-jaw cylinder to form a jaw plate structure. There are 3 pressing guide rods provided in the present application, and the corresponding jaw plate structure is a three-jaw jaw plate structure. Through the connection between the pressing members, linkage is achieved, so that when pressing the cage, pressing can be performed on a plane, and only one set of anti-collision sensing pieces and proximity switches needs to be provided. Handling and pressing the cage are more stable and efficient.

[0105] The difference from the above embodiments is that the claw head c11 is provided with a claw seat c14 having a seat groove, and the claw head backing plate c13 and the inner supporting claw c12 are detachably arranged in the seat groove of the claw seat in sequence, and the thickness of the backing plate is marked on the claw head backing plate. The claw seat can facilitate the positioning and installation of the claw head backing plate c13 and the inner supporting claw c12. The thickness value of the backing plate is set on the claw head backing plate, which can be accurately selected for cages of different models. In addition, the cage model can also be directly marked on the claw head backing plate for selection.
