Detailed Description

The invention will be further described with reference to specific embodiments and drawings.

It should be noted that the front and back surfaces described herein are not intended to limit the orientation of the ratchet wheel in practical applications, and the front and back surfaces described herein are intended to distinguish the relative definitions of the ratchet wheel teeth from the two different surfaces.

Example 1

An automatic tensioner ratchet assembly device, as shown in fig. 21 and 22, comprises:

a ratchet output 1000 that outputs a ratchet 6003 of the same tooth face, the same axial direction, and the same tooth direction;

a transfer rail 5000 for placing the tensioner 6000 to be assembled and transferring the tensioner 6000;

the ratchet wheel transmission unit 2000 is used for transmitting the ratchet wheel 6003 output by the ratchet wheel output end 1000 to a specified position of the tensioner 6000 to be assembled on the transmission track 5000;

the assembling presetting unit 3000 is arranged on the transmission rail 5000 and used for adjusting the relative position of the trip part 6001 and the stop part 6002 of the tensioner 6000 to be assembled;

and a correcting unit 4000 which is provided on the transfer rail 5000 and corrects the position of the ratchet 6003 of the tensioner 6000 after the ratchet 6003 is assembled.

As shown in fig. 19, a pair of ratchet wheels 6003 are fitted in a gap between the throw member 6001 and one end portion of the stopper 6002, and the ratchet wheels 6003 are engaged with the stopper 6002 and the pawl 6004, respectively, and the half shafts 6005 are fitted in a gap between the pair of ratchet wheels 6003 after the engagement. As shown in fig. 18, the number of the ratchet wheels 6003 assembled in the tensioner 6000 is singular, so the tooth directions of the front and the back surfaces thereof are different, and the tooth directions may also be different when the same surface is coaxial, and it is required to ensure that both the half shafts 6005 can be installed in the gap of the ratchet wheels 6003, and it is required to ensure that the axial directions of the assembled pair of ratchet wheels 6003 are the same, and it is required to ensure that the assembled pair of ratchet wheels 6003 are simultaneously engaged with the stopper 6002 and the fastener 6004, and it is required to ensure that the tooth directions of the pair of ratchet wheels 6003 are the same, so the ratchet output end 1000 is provided in this embodiment, and the ratchet wheels 6003 output through the ratchet output end 1000 are in the same surface, the same axial direction and the.

As shown in fig. 20, which is a top view of the tensioner 6000 to be assembled with the ratchet wheels 6003, after the tensioner 6000 to be assembled is transported to a specific position on the transport track 5000, the ratchet wheels 6003 output from the ratchet wheel output end 1000 are respectively transported to two ratchet wheel assembling positions 6030 of the tensioner 6000 to be assembled by the ratchet wheel transport unit 2000.

After the trip element 6001 and the stop element 6002 of the tensioner 6000 to be assembled are installed, the relative positions of the trip element 6001 and the stop element 6002 are inevitably deviated, which may cause the widths of two ratchet assembly positions 6030 not to simultaneously satisfy the width of the assembled ratchet 6003, and may cause the interference between the ratchet and the tensioner 6000 to be assembled when the ratchet transmission unit 2000 transmits the ratchet 6003, which may affect the assembly precision and success rate, and even may affect the precision of the set stroke of the ratchet transmission unit 2000, therefore, the present embodiment provides the assembly preset unit 3000, and before the ratchet 6003 is assembled, the assembly preset unit 3000 adjusts the relative positions of the trip element 6001 and the stop element 6002, so that the widths of the two ratchet assembly positions 6030 both satisfy the assembly condition of the ratchet 6003, thereby avoiding the interference between the ratchet 6003 and the tensioner 6000 when the ratchet 6003 is transmitted, ensuring the success rate when the ratchet is assembled, and avoiding the transmission precision of the ratchet transmission unit 2000 from being affected, the working efficiency of automatic assembly is ensured.

After the ratchet wheel 6003 is assembled at the ratchet wheel assembling position 6030 by the ratchet wheel transmission unit 2000, the ratchet wheel 6003 is not engaged with the engagement part of the stopper 6002 and the fastener 6004 of the tensioner 6000 to be assembled, the ratchet wheel transmission unit 2000 only performs the grabbing-transporting-placing operation on the ratchet wheel 6003 when the ratchet wheel 6003 is assembled, and the subsequent half shaft 6005 is installed after the ratchet wheel 6003 is engaged with the stopper 6002 and the fastener 6004, therefore, the correcting unit 4000 is provided in the embodiment, which is located along the transmission direction of the transmission rail 5000, and when the tensioner 6000 assembled with the ratchet wheel 6003 is transmitted to the position of the correcting unit 4000 by the transmission rail 5000 after the preset unit 3000 is assembled, the correcting unit 4000 corrects the assembled position of the ratchet wheel 6003, so that the ratchet wheel 6003 is engaged with the stopper 6002 and the fastener 6004, thereby completely completing the assembling of the ratchet wheel 6003 of the tensioner 6000.

Example 2

The tensioner ratchet automatic assembly device of the embodiment is further improved on the basis of the embodiment 1, and as shown in fig. 5 and 6, the tensioner ratchet automatic assembly device comprises:

a ratchet wheel input unit 1 for inputting a ratchet wheel 6003 on the same plane to the starting end of the direction-adjusting track 2;

the ratchet axial adjusting unit 3 is arranged on the direction adjusting track 2 and is used for adjusting the ratchet shaft of the input coplanar ratchet 6003 to be coaxial;

the ratchet wheel tooth direction adjusting unit 4 is arranged on the direction adjusting track 2 and is used for adjusting ratchet wheel teeth of the coaxial ratchet wheel 6003 to be in the same tooth direction;

the output unit 5 is arranged at the tail end of the direction-adjusting track 2 and is used for outputting the ratchet 6003 with the same axial direction and the same tooth direction;

and a transfer mechanism 6 for sequentially transferring the ratchet wheels 6003 on the direction-adjusting rail 2 to the units.

In the ratchet type tensioner 6000, two ratchets 6003 are installed on one tensioner 6000, when the tensioner 6000 is assembled, the half shaft 6005 needs to penetrate through a gap between the two ratchets 6003, the clamping piece 6004 and the blocking piece 6002 of the tensioner 6000 need to be engaged with ratchet teeth of the two ratchets 6003, and unidirectional intermittent motion can be performed, because the front and back tooth directions of the ratchets 6003 are different, and the forward and reverse tooth directions are also different, the states (the ratchet 6003 faces, the axial direction and the tooth direction) input by the two ratchets 6003 are completely the same when the ratchets 6003 are assembled, although the existing tensioner 6000 can achieve accurate input of the ratchets 6003, the time consumption is long, the efficiency is low, and the input state of the ratchets 6003 is difficult to be accurately controlled during automatic assembly, so the embodiment improves.

Due to the structural characteristics of the ratchet 6003, the ratchet teeth are composed of an arc side and a straight side, so the tooth direction of the ratchet 6003 is changed certainly after the face of the ratchet 6003 is adjusted, and because the tensioner 6000 ratchet 6003 adopts the ratchet 6003 with an odd number of teeth (the number of teeth of the ratchet 6003 in this embodiment is 11), even if the ratchet 6003 is the same face and the direction of the ratchet shaft is the same, the tooth directions may be different, as α and β in fig. 18, both are front ratchets 6003, and the direction of the ratchet shaft is the vertical direction, and the tooth directions of both are different, after the ratchet 6003 rotates 180 °, the tooth directions are the same as those of the α ratchet, γ and σ, both are back ratchets 6003, and the direction of the ratchet shaft is the vertical direction, and the tooth directions of both are different, and after the ratchet 6003 rotates 180 ° rotates the ratchet shaft is the same as those of γ, and it can also be found that the front ratchet 6003 and the back ratchets may not be the same even.

In the automatic tensioner ratchet assembling device of the embodiment, the ratchet 6003 sequentially passes through the ratchet input unit 1, the ratchet axial adjusting unit 3 and the ratchet tooth direction adjusting unit 4, and then enters the input unit 5 with the same face, axial direction and tooth direction. The ratchet input unit 1 screens the ratchet input direction adjusting tracks 2 facing to the same direction, the ratchet axial adjusting unit 3 enables the axial direction of the ratchet passing through the ratchet axial adjusting unit 3 to be consistent by rotating the ratchet, and the ratchet tooth direction adjusting unit 4 enables the tooth direction of the ratchet to be consistent by rotating the ratchet 6003 with the axial direction adjusted.

The state of the ratchet 6003 of the tensioner 6000 is accurately adjusted through the sequence of tooth surface screening, axial adjustment and tooth direction adjustment, and accurate conveying is carried out, wherein the sequence is the optimal sequence for adjusting the axial direction and the tooth direction of the ratchet 6003, and firstly, the tooth directions of different ratchets 6003 can never be adjusted to be consistent through rotation; the ratchet wheels 6003 which are identical in face and axial direction but different in tooth direction can be consistent in tooth direction only by rotating the ratchet wheels 6003 by 180 degrees; the ratchet wheels 6003 with consistent tooth direction but inconsistent axial direction have inconsistent tooth direction after the axial direction is changed to be consistent; the ratchet 6003 is more easily rotated than the ratchet 6003 is turned over, from the viewpoint of achieving the cost, accuracy, and stability of the apparatus; in summary, the device of the present embodiment can adjust the state of the ratchet 6003 screened in the same plane twice in a rotating manner, so as to accurately adjust the axial direction and the tooth direction thereof, without repeated adjustment, with high accuracy of adjustment and low cost.

The device of this embodiment adopts the succinctly most effectual order to adjust ratchet 6003 state, through apply screening, rotate the action back to ratchet 6003, transports to the ratchet 6003 of conveying unit 5 and be the syntropy, same axial, same direction of tooth, realizes ratchet 6003's accurate transport for strainer 6000 ratchet 6003's automatic installation must have been realized, and the accuracy is high, and conveying efficiency is fast.

an assembly preset unit lifting platform 3003 which is in transmission connection with the assembly preset unit driving piece 3002 and is driven by the assembly preset unit driving piece 3002 to perform lifting action;

the fixed claw 3004 consists of a telescopic rod and a clamping jaw, one end of the telescopic rod is fixedly connected to the bottom of the assembly preset unit lifting platform 3003, the other end of the telescopic rod is fixedly connected with the clamping jaw, and the distance between two claw arms of the clamping jaw is equal to the width of the blocking part 6002;

and the adjusting claw 3005 is fixedly connected to the bottom of the assembly preset unit lifting platform 3003, and the distance between two claw arms of the adjusting claw 3005 is equal to the width of the blocking piece 6002.

The fixed jaw 3004 and the adjusting jaw 3005 are located above the transmission rail 5000, when the tensioner 6000 to be assembled is transmitted to the assembly presetting unit 3000 by the transmission rail 5000, the assembly presetting unit driving member 3002 drives the assembly presetting unit elevating platform 3003 to descend, the length of the fixed jaw 3004 fixedly connected to the bottom of the assembly presetting unit elevating platform 3003 is larger than that of the adjusting jaw 3005, therefore, the fixed jaw 3004 is firstly contacted with the stopper 6002 of the tensioner 6000 to be assembled, the stopper 6002 is fixed in the two jaw arms of the fixed jaw 3004, the assembly presetting unit elevating platform 3003 continues to descend, the telescopic rod of the fixed jaw 3004 contracts under pressure, the adjusting jaw 3005 extends into a gap between the stopper 6002 and the trip member 6001 at one end of the tensioner 6000 to be assembled, namely the ratchet assembling position 6030, if the stopper 6002 and the trip member 6001 are not placed in parallel or the widths of the two ratchet assembling positions 6030 do not reach the width of the ratchet 6003, the relative position of the stop member 6002 and the trip member 6001 can be adjusted by the interference of the adjustment pawl 3005, and the width of the portion of the adjustment pawl 3005 extending into the ratchet assembly position 6030 matches the width required for assembling the ratchet 6003, so that the ratchet assembly position 6030 adjusted by the interference of the adjustment pawl 3005 can reach the assembly width of the ratchet 6003, and the ratchet transport unit 2000 can stably assemble the ratchet 6003 in place after the assembly preset unit lifting platform 3003 is reset.

Further, the assembly presetting unit 3000 of this embodiment is provided with a limiting pile, when the tensioner 6000 to be assembled is conveyed to the position right below the fixing claw 3004, the limiting pile extends out to stop the tensioner 6000 to be assembled at a fixed position, the limiting pile resets after the ratchet 6003 is assembled, and the tensioner 6000 continues to be conveyed along the conveying track 5000.

Further, in order to avoid that the adjusting effect is affected by the relative movement between the stopper 6002 and the trip member 6001 due to the influence of other factors such as vibration when the tensioner 6000 after being adjusted by the pre-adjustment unit 3000 is transported on the transport track 5000, the tensioner 6000 to be assembled is not moved in the original position after the pre-adjustment unit 3000 is adjusted in this embodiment, and the transmission is performed after the ratchet wheel 6003 is assembled on the ratchet wheel transport unit 2000.

Example 12

When the tensioner with the stopper 6002 and the trip member 6001 is transported on the transmission rail 5000, the tensioner is inevitably affected by vibration and other factors, and the relative position deviates, when the tensioner is transported to the assembly presetting unit 3000, if the deviation between the stopper 6002 and the trip member 6001 is too large, the fixed jaw 3004 may be caused to descend, and then the end of the jaw arm abuts against the top of the stopper 6002, and the fixed jaw 3004 cannot clamp the stopper 6002, therefore, in this embodiment, the inner side of the jaw tip of the fixed jaw 3004 is configured to be a smooth arc surface shape, and when the deviation between the stopper 6002 and the trip member 6001 is large, the fixed jaw 3004 may finely adjust the position of the stopper 6002 during the descending process, so that the two jaw arms of the fixed jaw 3004 can smoothly clamp the stopper 6002 without abutting against the top of the stopper 6002.

The adjusting claw 3005 of this embodiment is wedge-shaped, and the width of the narrow end of the claw tip is less than the width of the ratchet 6003, when the deviation between the stopper 6002 and the trip piece 6001 of the tensioner 6000 transported to the pre-adjusting unit 3000 is too large, the gap between the stopper 6002 and the trip piece 6001 may be too small, and at this time, the adjusting claw 3005 using the wedge-shape is more easily inserted into the gap between the stopper 6002 and the trip piece 6001 to perform interference adjustment, so that the occurrence of the condition that the claw 3005 abuts against the top of the stopper 6002 is greatly reduced.

In the embodiment, the claw tips of the fixing claws 3004 are designed into smooth arc surfaces, and the claw tips of the adjusting claws 3005 are designed into wedge shapes, so that the adjustable application range of the assembly preset unit 3000 is increased, the stopper 6002 and the wrench part 6001 at some limit positions can be adjusted, the condition that the claw tips are dead against the top of the stopper 6002 during adjustment is greatly reduced, the fault occurrence rate is reduced, and the accuracy during assembly is ensured.

Relative to the assembly pre-adjusting unit 3000, the correcting unit 4000 is located at the downstream position of the transmission track 5000, that is, the tensioner 6000 to be assembled firstly passes through the assembly pre-adjusting unit 3000 and then reaches the correcting unit 4000 under the transmission of the transmission track 5000; each component on the correction unit 4000 is fixed above the conveying track 5000 through a correction unit base frame 4001; a driving piece of the z-direction transmission mechanism 4002 of the correction unit is an air cylinder, is fixedly connected to the correction unit base frame 4001 and is positioned above the transmission rail 5000; the correction unit lifting table 4003 is in transmission connection with the bottom driving output end of the correction unit z-direction transmission mechanism 4002, and is driven by the correction unit z-direction transmission mechanism 4002 to move close to or away from the transmission guide rail 5000; the bottom of the correction unit lifting table 4003 is fixedly connected with a correction unit y-direction transmission mechanism 4004, a driving piece of the correction unit y-direction transmission mechanism 4004 is an air cylinder, the correction mechanism 4005 is in transmission connection with a driving output end of the correction unit y-direction transmission mechanism 4004, and the correction unit y-direction transmission mechanism 4004 can drive the correction mechanism 4005 to move in the y direction; the correcting claw x of the correcting mechanism 4005 is a double-head cylinder towards the driving part 4051, and is in transmission connection with the driving output end of the correcting unit y towards the transmission mechanism 4004, the correcting claw x drives the correcting claws 4050 at two ends of the correcting claw x towards the driving part 4051 to perform opening and closing movement, each claw arm is provided with a group of convex limiting cores 4052, and each group of limiting cores 4052 can clamp the ratchet shaft of the ratchet 6003.

The manipulator 2005 of the ratchet transmission unit 2000 of the present application can only perform simple grabbing and placing actions on the ratchet 6003, and the ratchet transmission unit 2000 of the present application is set to only place the ratchet 6003 in a specific state output by the ratchet output end 1000 from the output disc 50 in two ratchet assembling positions 6030 of the tensioner 6000, and only simply placing the ratchet 6003 cannot mesh the ratchet 6003 with the stopper 6002 and the clamper 6004, so the calibration unit 4000 is designed in this embodiment, when the tensioner 6000 is transmitted to the calibration unit 4000, the calibration unit 4000 is also provided with a limiting post, the tensioner 6000 is limited on the transmission rail 5000 directly below the calibration mechanism 4005, and since the stroke of the manipulator 2005 in the ratchet transmission unit 2000 is fixed, the relative positions of the ratchets 6003 on both sides of the tensioner 6000 are fixed; under the drive of the transmission mechanism 4002 in the z direction of the correction unit, the correction claws 4050 of the correction mechanism 4005 are lowered to the height position of the ratchet 6003 of the tensioner 6000, the height of the limit cores 4052 is just matched with the height of the ratchet shaft, the correction claws 4050 move in a closing manner under the drive of the correction claw x to the driving piece 4051, each group of the limit cores 4052 respectively clamp the ratchet shaft on one side, under the drive of the transmission mechanism 4004 in the y direction of the correction unit, the correction claws 4050 push the stopper 6002 and the clamping piece 6004 in the direction, and during the pushing action, the limit cores 4052 interfere with the ratchet 6003 to push the ratchet 6003 to be engaged with the stopper 6002 and the clamping piece 6004, then, the correction claw 4050 moves to open, and the components of the correction unit 4000 reset, so that the automatic assembly of the ratchet of the tensioner is completed.

In the automatic tensioner ratchet assembling device of the embodiment, the correcting unit 4000 pushes the tensioner 6000 ratchet 6003 with the ratchet 6003 placed therein, and the installed ratchet 6003 is corrected to be in a state of being engaged with the stopper 6002 fastener 6004 by a simple and effective action, so that the correcting is fast, the efficiency is high, and the assembling power is high.

The reason why the ratchet wheel transmission unit 2000 corrects the ratchet wheel 6003 while placing the ratchet wheel 6003 is not designed in this embodiment is that setting a complicated action command for one unit increases the failure rate of the unit, and setting too much action for the same unit also causes an error in action implementation, which adversely affects the assembly power, and when performing multiple actions for the same unit, the processing rate will be reduced, and the placing and correcting actions for the ratchet wheel 6003 can be performed separately, i.e., when placing the ratchet wheel 6003 for the tensioner 6000, the tensioner 6000 with the ratchet wheel 3 placed therein can be simultaneously corrected, so that the arrangement not only saves the assembly time and accelerates the processing efficiency, but also reduces the number of actions to be implemented for each unit, which is easy to implement, has a high success rate and a low failure rate, and has a relatively low demand for the performance of the apparatus, the production cost is greatly reduced in a long term.
