Description

Technical Field

[0001] The present invention relates to the technical field of garden folding devices, in particular to a folding device for garden tools and processing equipment thereof. Background Art

[0002] Since garden tools need to trim the branches and leaves of trees, they need to use longer poles to extend the garden tools to the height of the tree branches and leaves. However, longer poles are difficult to transport, so the poles need to be folded and placed during transportation.

[0003] Since the rod is used to lift garden tools, the mechanical strength of the folding device needs to be guaranteed. For example, the rod described in the patent with publication number CN214800814U is made of aluminum. The folding device is wrapped around the rod and locked on the rod by deformation and compression. Considering the mechanical strength, the folding device is die-cast. However, the die-cast workpiece may have invisible cracks or bubbles, and may break when deformed and compressed. In order to ensure the personal safety of the user, each folding device must be tested to ensure that it will not break during deformation. Summary of the Invention

The drilling unit includes a drilling part that can move up and down to drill a hole in the first connection part located on the clamping device. The deformation detection unit includes a lifting and clamping rod, which is used to press the locking protrusion on the first connection part to deform it. The clamping rod is provided with a pressure detection unit to detect the pressure change during the clamping process. If the pressure suddenly decreases, it is judged that a crack has occurred.

[0007] Its beneficial effect is that after drilling is completed, the workpiece is automatically subjected to a deformation test, and whether cracks are generated is determined by pressure changes, thereby ensuring that each workpiece is subjected to a deformation test, thereby improving the safety of the folding device.

[0008] In the above scheme, preferably, the clamping device includes a cavity seat and a clamping member slidingly configured on the cavity seat, and the cavity seat is provided with an accompanying cavity adapted to the first connecting part or the second connecting part, and the clamping member is used to clamp the first connecting part or the second connecting part.

[0011] In the above scheme, preferably, a second inclined surface is arranged on the front end face of the locking block. When clamping, the second inclined surface touches the front end wall of the locking groove, and the elastic force exerted on the locking block is greater than the elastic force exerted on the clamping member, so that the locking block exerts a pressing force on the clamping member toward a component of the folding device through the second inclined surface.

[0012] In the above scheme, preferably, the base is also provided with a supporting device, which includes a ring frame, and a telescopic part is connected to the ring frame to drive the ring frame in and out of the deformation detection unit station.

[0023] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1:

[0024] See also Figure 1-Figure 7, a folding device for garden tools includes a first connecting part 61 and a second connecting part 62, the side surfaces of one end of the two are hinged together by a pin limit, the first connecting part 61 and the second connecting part 62 are tubular parts, and are both provided with a plurality of locking protrusions 611, a deformation groove 612 is provided on the locking protrusion, and a locking hole 613 is provided on the locking protrusion, and the locking hole 613 is perpendicular to the deformation groove 612, and a threaded part is passed through the locking hole to deform the tubular part and then fix it on the rod of the equipment, and the deformation groove 612 is deformed. The two connecting parts are die-cast parts, and the die-cast parts will have invisible cracks. When in use, the connecting parts need to be deformed and compressed, so the invisible cracks will be revealed during use, and then breakage will occur. Therefore, it is necessary to perform pre-pressure detection on the connecting parts to screen out the connecting parts with quality problems.

[0025] The processing equipment includes a base frame 1, on which a circulation unit 2, a drilling unit 3, a deformation detection unit 4 and a supporting device 5 are configured. The circulation unit 2 includes a turntable 21 rotatably configured on an upright frame 12 of the base 1. The upright frame 12 is also configured with a power device, which is connected to the turntable 21, so that the driving motor can drive the turntable 21 to rotate. The power device includes a separator and a driving motor configured on the separator, wherein the rotation of the driving motor can drive the main shaft of the separator to continue rotating after pausing after each 90 rotations, so that the turntable 21 can stop rotating after rotating 90 degrees.

[0026] The turntable 21 is provided with two clamping devices 22, which are respectively arranged at both ends of the turntable 21, and the processing equipment is provided with two workstations, namely a drilling station and a deformation station. In the initial state, the two clamping devices 22 on the turntable 21 are respectively located at the drilling station and the deformation station. After the turntable 21 rotates 180 degrees, the positions of the clamping devices 22 on the two stations are interchanged.

[0027] The clamping device 22 includes a cavity seat 221, and the cavity seat 221 is provided with an accompanying cavity 2212 adapted to the first connecting part 61 or the second connecting part 62. The first connecting part 61 or the second connecting part 62 can move left and right in the accompanying cavity 2212, thereby facilitating the insertion or removal of the first connecting part 61 or the second connecting part 62. The cavity seat 221 is also provided with a guide groove 2211, and a clamping member 222 is configured on the guide groove 2211 for guiding sliding. The clamping member 222 is used to cooperate with the accompanying cavity 2212 to position and press the first connecting part 61 or the second connecting part 62 inserted therein. Tight, and a first elastic member 2213 is further arranged in the guide groove 2211, one end of the first elastic member 2213 touches the front end surface of the guide groove 2211, and the rear end touches the clamping member 222, and then in the initial state, the clamping member 222 is acted upon by the first elastic member 2213, and the rear end touches the rear end surface of the guide groove 2211, and then the distance between the accompanying cavity 2212 and the clamping member 222 is larger, and the first connecting part 61 or the second connecting part 62 can move back and forth within the distance between the two, so that the first connecting part 61 or the second connecting part 62 is easy to put in and take out.

[0028] A sliding cavity 2214 is also provided on the side wall of the guide groove 2211, and a locking block 223 is configured to guide the sliding inside the sliding cavity 2214. The locking block 223 is used to lock the first connecting part 61 or the second connecting part 62 when the clamping member 222 clamps it. The rear end face of the locking block 223 contacts one end of the second elastic member 224, and the other end contacts the rear end face of the sliding cavity 2214, so that the locking block 223 is in an extended state in the initial state, and its extended position is in the guide groove 2211. A locking groove 2221 is provided on the clamping member 222. When the front end of the locking block 223 is located in the locking groove 2221, the clamping member 222 clamps the first connecting part 61 or the second connecting part 62 in the accompanying cavity 2212.

[0029] The front and rear end surfaces of the protruding end of the locking block 223 along the direction of the guide groove 2211 are respectively provided with a first inclined surface 2231 and a second inclined surface 2232, and a pushing member 11 is provided on the base 1. The pushing member 11 is a telescopic cylinder, which is located on the drilling station and extends forward. The front end of the telescopic rod touches the clamping member 222, thereby pushing the clamping member 222 to move forward along the guide groove 2211, and cooperates with the accompanying cavity 2212 to tighten the first connecting part 61 or the second connecting part 62. At this time, the drilling member 31 on the drilling station moves downward to drill the locking protrusion 611. After the drilling is completed, the pushing rod 11 retracts to its original position.

[0030] When the locking member 222 is in the forward position, the locking member 223 is pressed against the first connecting portion 61 or the second connecting portion 62, and the second inclined surface 2232 of the locking member 223 is pressed against the cutting edge of the front end of the locking groove 2221, thereby the locking member 223 gives the clamping member 222 a pushing force toward the first connecting portion 61 or the second connecting portion 62. At the same time, since the elastic force of the second elastic member 224 is greater than the elastic force of the first elastic member 2213, Therefore, when drilling is completed and the pushing member 11 is retracted, the elastic force of the first elastic member 2213 is not enough to push the clamping member 222 to recover backward. Therefore, under the action of the second elastic member 224, the first connecting part 61 or the second connecting part 62 is still clamped, so that the first connecting part 61 or the second connecting part 62 will not fall off when the turntable 21 rotates.

[0031] The rear end of the locking block 223 is connected to one end of a pull rope, and the bottom surface of the cavity seat 221 is slidingly configured with an unlocking rod 225, and the other end of the pull rope is configured on the lower end of the unlocking rod 225. When the unlocking rod 225 is subjected to pressure on the cavity seat 221, the unlocking rod 225 slides into the bottom surface of the cavity seat 221, and the unlocking rod 225 slides downward and pulls the locking block 223 to slide into the sliding cavity 2214 through the pull rope. Then, when the unlocking rod 225 slides downward, the locking block 223 releases the lock on the clamping member 222, and the clamping member 222 returns to its initial state under the action of the first elastic member 2213. After the pressure contact force of the unlocking rod 225 disappears, the pulling force on the locking block 223 disappears, and then under the action of the second elastic member 224, the locking block 223 extends outward, and at the same time, the unlocking rod 225 is driven to extend outward through the pull rope.

[0032] The upright frame 12 is also provided with a hydraulic lifting member 13, and a lifting plate 14 is provided on the telescopic rod of the hydraulic lifting member 13. The lifting plate 14 is located above the drilling station and the deformation station, and the drilling unit 3 and the deformation detection unit are arranged on the lifting plate 14. When the turntable 21 is to be rotated, the central control unit controls the hydraulic lifting member 13 to retract, and then the lifting plate 14 drives the drilling unit 3 and the deformation detection unit to leave the rotation path of the turntable 21. After the rotation is completed, the hydraulic lifting member 13 extends downward, and the lifting plate 14 drives the drilling unit 3 and the deformation detection unit back to the processing station.

[0033] The drilling unit 3 includes a plurality of drilling members 31 that can be lifted up and down, wherein the number and position of the drilling members 31 are adapted to the locking protrusion 611 on the first connecting part 61 or the second connecting part 62, and when the clamping device 22 clamps the first connecting part 61 or the second connecting part 62, the drilling member 31 is located above the locking protrusion 611, and then the drilling member 31 starts to rotate, and the locking hole 613 is drilled during the descent. At the same time, a through hole 2215 is opened on the cavity seat 221, and the through hole 2215 is aligned with the drilling member 31, and the number and position are consistent with the drilling member 31. At the same time, the diameter of the through hole 2215 is larger than the diameter of the drill bit of the drilling member 31. Therefore, when drilling, the drill bit can extend downward from the through hole 2215, thereby completely drilling the locking hole 613.

[0034] Among them, the two clamping devices 22 on the turntable 21, the accompanying cavity 2212 of the clamping device 22 located below the drilling unit 3 faces upward, and then at the beginning, the robot or manual workpiece is placed on the accompanying cavity 2212, and then the pushing member 11 pushes the clamping member 222 to clamp the workpiece, and then the drilling operation is performed. The clamping device 22 located at the deformation station is exactly opposite to the clamping device 22 located at the drilling station, and its accompanying cavity 2212 faces downward. After the turntable 21 rotates 180 degrees, the clamping device 22 originally located at the drilling station is just interchanged with the clamping device 22 located at the deformation station.

[0035] The deformation detection unit includes a lifting and pressing rod 41, which is equipped with a pressure detection unit, wherein the pressure detection unit is a pressure sensor that can identify pressure changes. The number of lifting and pressing rods 41 is consistent with the number of drilling members 31, and they are adapted to the locking protrusions 611 on the workpiece. The support device 5 is used to support the workpiece, so that when the lifting and pressing rods 41 are pressed downward, a supporting force is applied from below the workpiece.

[0036] The supporting device 5 includes an annular frame 51, a supporting seat 52 and a telescopic member 53. The telescopic member 53 is fixedly arranged on the base frame 1, the annular frame 51 is fixedly arranged on the telescopic rod of the telescopic member 53, and the support seat 52 is elastically guided and slidably arranged on the annular frame 51. Then, the telescopic member 53 can move back and forth to drive the annular frame 51 and the supporting seat 52 to move back and forth, thereby extending the supporting seat 52 into the deformation station or detaching it from the deformation station.

[0037] The base frame 1 is provided with a pressure block 15 at a position below the deformation station, the support seat 52 is provided with the same number of support rods 521 as the locking protrusions 611 on the workpiece, and a plurality of nozzles are provided on the inner wall of the annular frame 51. The nozzles are connected to the liquid storage tank through pipes, and a liquid pump is provided on the pipes, so that when the liquid pump is started, the nozzles can spray the color developer outward.

[0038] The 4-station separator is what drives the turntable 21 to rotate. When the driving motor drives it to work, it drives the turntable 21 to rotate 90 degrees each time, and it rotates 180 degrees after rotating two stations. After the workpiece is rotated, the turntable 21 rotates to bring the workpiece to the deformation station. After the turntable 21 rotates 90 degrees, the telescopic member 53 begins to extend, and the annular frame 51 and the support seat 52 are sent to the deformation station. The support seat 52 is located above the pressure block 15. At this time, the turntable 21 rotates another 90 degrees to drive the drilled workpiece into the deformation station. At this time, the cavity seat 221 is facing downward, and the lower end face of the locking protrusion 611 of the workpiece pressed in the cavity seat 221 is pressed against the support rod 521. At this time, the pressing member 222 is still in a locked state. At this time, the hydraulic lifting member 13 drives the deformation detection unit back to the station. The deformation detection unit also includes a pressure touch plate 42. The pressure touch plate 42 guides It is slidingly configured on the lifting plate 14, and a third elastic member is also configured between the pressure touch plate 42 and the lifting plate 14. After the lifting plate 14 drops into place, the pressure touch plate 42 presses on the bottom surface of the cavity seat 221, and at the same time presses the unlocking rod 225 into the bottom surface of the cavity seat 221, thereby unlocking the clamping member 222, and the clamping member 222 contacts the clamping lock of the workpiece. Under the action of its own gravity, the workpiece drives the support seat 52 to slide downward, compressing the elastic member supporting it, and finally the support seat 52 presses on the pressure block 15, and the pressure block 15 supports the support seat 52. At this time, the workpiece is located in the annular surround of the annular frame 51, and the nozzle on the annular frame 51 is aligned with the workpiece on the support seat 52.

[0039] At this time, the deformation pressure test begins, and the lifting and clamping rod 41 begins to descend, enters the cavity seat 221 from the through hole 2215 of the cavity seat 221, and continues to descend and presses on the upper end surface of the locking protrusion 611 of the workpiece. The lifting and clamping rod 41 continues to press downward, thereby deforming the locking protrusion 611. After the lifting and clamping rod 41 drops to the lowest point, it returns to its initial state. The lowest point of downward pressure is set separately according to different locking protrusions 611, so the locking protrusions 611 at different positions on the workpiece are subjected to deformation pressure tests separately, and during the downward deformation process, the pressure detection unit continuously records the pressure change value. During the downward pressure process, the pressure value suddenly drops rapidly. At this time, the reverse support force of the workpiece on the lifting and clamping rod 41 suddenly drops. It will only drop suddenly when the workpiece breaks or cracks. Therefore, when this state occurs, it is determined that the workpiece has cracks.

[0040] When it is determined that cracks or fractures occur, the central control unit controls the nozzle to spray the developer, so that the developer penetrates into the cracks, so that after the workpiece is restored to its initial state by the lifting and clamping rod 41, when there is no more pressure on the workpiece, the cracks can be displayed by the developer.

[0041] After the deformation pressure test is completed, the lifting and clamping rod 41 has returned to its initial state, and the telescopic part 53 begins to shrink, pulling the annular frame 51 and the support seat 52 out of the deformation station. At this time, the workpiece that has completed the inspection is located on the support seat 52. After the telescopic part 53 shrinks, the workpiece is removed mechanically or manually for classification and placement.

[0042] Its working principle or usage is as follows: In the initial state, the two clamping devices 22 on the turntable 21 are in an idle state, and both are in a horizontal state. The rear end of the clamping member 222 touches the rear end surface of the guide groove 2211 under the action of the first elastic member 2213. At this time, the robot or manual workpiece, that is, the first connecting part 61 and the second connecting part 62, is positioned and placed into the accompanying cavity 2212 of the cavity seat 221 of the drilling station. At this time, the start switch is pressed manually or the central control unit control device is started, and then the push member 11 begins to extend, and the front end of the telescopic rod touches the clamping member 222, pushing the clamping member 222 to move forward along the guide groove 2211, and cooperate with the accompanying cavity 2212 to press the first connecting part 61 or the second connecting part 62.

[0043] At this time, the telescopic rod of the hydraulic lifting component 13 descends, thereby driving the drilling unit 3 and the deformation detection unit downward together, so that the drilling unit 3 and the deformation detection unit enter the work station. After the hydraulic lifting component 13 descends into place, the drilling component 31 begins to rotate and descend to drill the workpiece clamped in the accompanying cavity 2212. After descending to the lowest point, that is, the lower end of the drill bit on the drilling component 31 extends from the lower end of the through hole 2215, the drilling component 31 ascends and returns to its initial state. The hydraulic lifting component 13 starts to ascend, driving the drilling unit 3 and the deformation detection unit to leave the rotation path of the clamping device 22.

[0044] As the hydraulic lifting member 13 moves upward, the pushing member 11 begins to contract, thereby canceling the pressure on the clamping member 222, and a locking block 223 is provided on the guide groove 2211. The locking block 223 continues to lock the clamping member 222 after the pushing member 11 leaves, and the clamping member 222 still presses the workpiece to prevent it from falling during the rotation process.

[0045] After the hydraulic lifting member 13 completes the upward movement, the turntable 21 rotates to bring the workpiece to the deformation station. The turntable 21 rotates 90 degrees, and the telescopic member 53 begins to extend, sending the annular frame 51 and the support seat 52 to the deformation station. The support seat 52 is located above the pressure block 15. At this time, the turntable 21 rotates another 90 degrees to drive the drilled workpiece into the deformation station, and the cavity seat 221 is facing downward at this time. The lower end face of the locking protrusion 611 of the workpiece pressed in the cavity seat 221 is pressed against the support rod 521. At this time, the clamping member 222 is still in a locked state.

[0046] At this time, the clamping device 22 that was originally located in the deformation station and was empty is transferred to the drilling station. The robot or manual staff places the new workpiece in the accompanying cavity 2212. After the placement is completed, it is locked by the pusher 11, so that when the lifting plate 14 drives the drilling unit 3 to descend and return to the drilling station, the drilling unit 3 can drill the new workpiece.

[0047] At this time, the hydraulic lifting member 13 drives the deformation detection unit to descend and return to the work station, and the pressure touch plate 42 presses on the bottom surface of the cavity seat 221, pressing the unlocking rod 225 into the bottom surface of the cavity seat 221, thereby unlocking the clamping member 222, and the clamping member 222 contacts the clamping lock of the workpiece. Under the action of its own gravity, the workpiece drives the support seat 52 to slide downward, compressing the elastic member supporting it, and finally the support seat 52 presses on the pressure block 15, and the pressure block 15 supports the support seat 52. At this time, the workpiece is located in the annular enclosure of the annular frame 51, and the nozzle on the annular frame 51 is aligned with the workpiece on the support seat 52. At this time, the clamping device 22 in the deformation station is in an unlocked and idle state.

[0048] At this time, the deformation pressure test begins. The lifting and clamping rod 41 descends and presses on the upper end surface of the locking protrusion 611 of the workpiece. The lifting and clamping rod 41 continues to press downward, thereby deforming the locking protrusion 611. After the lifting and clamping rod 41 descends to the lowest point, it returns to its initial state. During the downward deformation process, the pressure detection unit continuously records the pressure change value. The pressure value suddenly drops rapidly. It will only drop suddenly when the workpiece breaks or cracks. Therefore, when this state occurs, it is determined that the workpiece has cracks.

[0049] When cracks or fractures are detected, the central control unit controls the nozzle to spray the developer, allowing the developer to penetrate into the cracks. After the workpiece is restored to its initial state by the lifting and clamping rod 41, the cracks can be displayed by the developer when no pressure is applied to the workpiece.

[0050] After the deformation pressure test is completed, the lifting and clamping rod 41 has returned to its initial state, and the telescopic part 53 begins to shrink, pulling the annular frame 51 and the support seat 52 out of the deformation station. At this time, the workpiece that has completed the inspection is located on the support seat 52. After the telescopic part 53 shrinks, the workpiece is removed mechanically or manually for classification and placement.

[0051] Example 2:

[0052] Compared with embodiment 1, the difference lies in the structure of driving the rotating disk 21 to rotate, and the rest are the same. Figure 1-Figure 7The turntable 21 is rotatably configured on the upright frame 12, and a servo motor with a brake is also configured on the upright frame 12. The rotating shaft of the servo motor is connected to the rotating shaft of the turntable 21. The turntable 21 is driven by the servo motor to achieve precise rotation, and the rotation speed is controllable, so that the telescopic member 53 is extended after it rotates more than 30 degrees.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
