Description

  The present invention relates to a strut assembly assembling apparatus used as a vehicle suspension apparatus.

  A suspension device equipped in a vehicle connects a vehicle body and an axle support member below the vehicle body, and receives a vehicle body load and a link member that holds the wheel in a predetermined alignment state, and transmits the load to the wheel via the link member. A spring that supports the wheel reaction force while interfering with the wheel reaction force and a shock absorber that absorbs and attenuates vehicle body vibration based on the wheel reaction force are provided. One suspension is a strut suspension. This strut type suspension has a steering knuckle fixed to the lower end of the outer cylinder of the strut with a built-in shock absorber, and a coil spring is mounted between the lower seat provided on the outer periphery of the outer cylinder and the upper seat attached to the upper end of the shock absorber. The upper seat side is fastened to the upper part of the vehicle body, and the lower end of the outer cylinder of the strut is connected to the knuckle. In this strut type suspension, the center line of the coil spring and the center line of the shock absorber are not mounted coaxially, but the center line of the coil spring is mounted eccentrically so as to cancel the bending stress of the strut due to the road surface reaction force. ing.

  In assembling the strut assembly of such a strut type suspension, a strut assembly assembling apparatus is used. As an example, an assembly device that mechanically pulls the upper end of a rod from an outer cylinder fixed to a base frame before assembly, and fastens a nut after fitting an upper bracket or the like to the upper end is disclosed in Japanese Utility Model Publication No. 60-12788. Document 1).

  For example, in a strut assembly assembling apparatus as shown in FIG. 13, shock absorber clamping means 201 is provided on the side wall of the strut assembly receiving base 200, thereby detachably holding the lower outer cylinder of the shock absorber 202 before temporary assembly. The lower end joint portion 203 is placed on the cradle 204 side, and the strut assembly SA is supported along the sandwiching center line La.

  In this way, in the pre-assembled strut assembly SA supported by the strut assembly cradle 200, the lower end of the coil spring 206 is placed on the lower seat 205 that is fixedly protruded to the outer peripheral surface of the outer cylinder of the shock absorber 202. Then, an upper sheet (not shown) is fitted to the upper end of the piston rod 207 protruding from the upper outer cylinder of the shock absorber 202, and a nut is fastened to the upper end. Prior to the mounting of the upper seat, the coil spring 206 is compressed by a predetermined amount downward from above by a strut assembly assembling apparatus (not shown) along the clamping center line La. The upper end hooks 209 of a pair of left and right spring locking members 208 that are pin-coupled to the lower portion of the base) are locked and held. An upper seat is placed on the upper end of the coil spring 206 in the compressed state, and a nut is fastened to the upper end of the piston rod 207.

  Furthermore, Japanese Patent No. 3356038 (Patent Document 2) discloses a strut assembly assembling apparatus in which functional parts similar to those of the above-described strut assembly receiving base 200 are provided on the four side surfaces of the turntable.

  In this assembly apparatus using the turntable method, the struts are held on the four side surfaces of the turntable, respectively, the coil springs are supplied to the struts on the first work stage and compressed, and the compressed state is maintained. The coil spring as it is is held by the work holder, the rod of the strut is pulled out in the second work stage, the upper sheet is assembled on the upper part, and the mount insulator is assembled on the upper sheet of the strut in the third work stage. A nut is fastened to the upper part of the attachment rod, and in the fourth work stage, the respective steps of releasing the coil spring from the work holder and taking out the strut assembly from the turntable are sequentially performed.

Japanese Utility Model Publication No. 60-12788 Japanese Patent No. 3356038

  By the way, the center line Lc of the coil spring and the sandwiching center line La, which is the center line of the shock absorber, are not provided coaxially (see FIG. 13). Is set to receive properly. Thus, in the strut assembly SA designed to cancel the bending stress of the strut, the center line Lc of the coil spring is inclined and shifted with respect to the center line (clamping center line) La of the shock absorber. In the assembly operation of the assembly SA, when the coil spring 206 is compressed downward, the lower end portion of the coil spring 206 and the lower sheet 205 are pressed by the pressing force F1 in the direction of the center line Lc of the coil spring. Thereby, the compression force F2 in the direction of the clamping center line La of the shock absorber clamping means 201 and the component force F3 in the direction away from the clamping center line La act on the strut assembly SA, and the upper side of the strut assembly SA tends to be inclined and displaced e. is there.

  As described above, when the upper outer cylinder side of the shock absorber is inclined, the work efficiency of the subsequent fitting of the upper seat to the upper end of the piston rod 207 and the fastening of the nut to the upper end thereof is lowered. In particular, in this case, it takes time to insert and fit the upper end of the piston rod 207 into an insulator (not shown) that is incorporated at the same time as the upper seat, and also to the operation of screwing the nut to the upper end of the piston rod 207 by a nut runner (not shown). This will cause troublesome work and decrease in workability. Such a decrease in workability is not solved by the techniques of Patent Document 1 and Patent Document 2.

  For this reason, when the coil spring is compressed during the assembly of the strut assembly, the center line of the coil spring and the center line of the shock absorber can be prevented from shifting, and the strut can be prevented from tilting. There is a demand for a strut assembly assembling apparatus that can reliably prevent the inclination of the struts even if there is a difference in the shape of the seat and can improve the workability during the assembly of the strut assembly.

  The present invention has been made paying attention to the above-mentioned problems. The center line of the coil spring and the center line of the shock absorber are deviated, so that the strut is inclined in the compression process of the coil spring at the time of assembling the strut assembly. It is an object of the present invention to provide a strut assembly assembling apparatus that can reliably prevent this and improve workability during assembling of the strut assembly.

  In order to achieve the above-mentioned object, the invention according to claim 1 is a shock absorber holding method in which a shock absorber of a strut assembly is detachably held on a side wall of a vertical support base that extends upward from a lower base fixed to a floor. A strut assembly pedestal having a means, and a shock absorber which is mounted on the strut assembly cradle and supported along the clamping center line of the shock absorber clamping means, and a coil spring is temporarily assembled and compressed. Next, a strut assembly assembly means for performing a nut fastening process after assembling the upper seat of the strut assembly, and a shift in a switching direction orthogonal to the clamping center line of the lower seat of the strut assembly supported by the strut assembly receiving base. Regulatable Loasi A lower sheet support means, the lower sheet support means being supported so as to be movable in a direction orthogonal to the sandwiching center line, and a plurality of contact portions with which the peripheral edge portion of the lower sheet is in contact with the switching direction. And a displacement regulating means capable of preventing displacement in the switching direction of the lower sheet receiving member.

  According to a second aspect of the present invention, in the strut assembly assembling apparatus according to the first aspect, the shift regulating means is removably engaged with a rack formed on the side wall of the lower sheet receiving member so as to be detachable from the lower seat. It is formed as a ratchet mechanism portion comprising a ratchet claw capable of preventing the shift of the receiving member in the switching direction.

  According to a third aspect of the present invention, in the strut assembly assembling apparatus according to the first or second aspect, the plurality of contact portions are arranged in a stepped manner along the switching direction on the upward surface of the lower sheet receiving member. It is characterized by that.

  According to a fourth aspect of the present invention, in the strut assembly assembly device according to the first, second, or third aspect, one of a plurality of abutting portions of the lower sheet receiving member is a peripheral edge of the lower sheet. A link for applying a driving force in the switching direction so as to abut the portion and a switching driving means for transmitting the driving force to the link are connected.

  According to the first aspect of the present invention, the lower seat supporting means is provided on the upper part of the strut assembly receiving base, and one of the plurality of abutting portions arranged on the lower seat supporting means is used for the strut assembly being assembled. Because it can abut on the periphery, even if a load in the direction perpendicular to the clamping centerline is applied to the strut assembly during assembly of the coil spring, the lower seat support means together with the shock absorber clamping means prevents the strut assembly from tilting. In addition, it is possible to prevent the shift in the switching direction perpendicular to the clamping center line of the strut assembly being assembled, and the subsequent temporary assembly and nut fastening process on the upper seat side can be easily and reliably performed.

  According to the invention of claim 2, since the ratchet mechanism portion allows movement toward the sandwiching center line of the lower sheet receiving member, it can be easily prevented from shifting in the switching direction orthogonal to the sandwiching center line. During assembly of the coil spring, the peripheral portion of the lower sheet receiving member can be easily brought into contact with one of the contact portions of the lower sheet receiving member with good operability, and the lower sheet receiving member has received an external force in the inclined direction. The lower sheet receiving member can be prevented from shifting in the switching direction in conjunction with the above.

  According to the invention described in claim 3, even if the lower seat supporting means is pushed and moved so as to approach the clamping center line side, even if the strut assemblies have different shapes, a stepped shape is formed on the periphery of each lower seat. Thus, it is possible to reliably abut one of a plurality of abutting portions arranged in a row, and to easily prevent the tilt of the strut assembly, and to perform subsequent temporary assembly and nut fastening processing on the upper seat side with certainty.

  According to the invention of claim 4, the driving force of the driving means is transmitted to the lower sheet receiving member via the link, and one of the contact portions of the lower sheet receiving member is easily brought into contact with the peripheral portion of the lower sheet. Thus, the work of bringing the contact portion of the lower sheet receiving member into contact with the peripheral portion of the lower sheet is facilitated.

In this state, it is assumed that the upper and lower sides of the shock absorber 4 of the strut assembly S before assembly are fitted into the upper and lower outer cylinder clamping portions 17 and 18 and a clamping command is input to the control means 16 by the operator. Thereby, the control means 16 switches the upper and lower outer cylinder clamping parts 17 and 18 to the clamping position.

Next, the control means 16 turns off the air cylinder 79 of the switching means 78 (see FIG. 3). As a result, the lever 76 of the switching means 78 is switched to the reference position P1 side by the return spring 77, and in conjunction with this, the slide base 73 and the lower sheet holder 74 are directed to the placement position Q1 (see FIG. 2A). To move.
At this time, one of the plurality of contact portions c1 to cn of the lower sheet receiving member 74 comes into contact with the peripheral edge portion of the lower sheet S4 of the strut assembly S and stops. At this time, the ratchet function of the deviation regulating means 81 allows the movement of the lower sheet holder 74 toward the clamping center line La, and can easily prevent the deviation in the separating direction (direction perpendicular to the clamping center line). Therefore, during the assembly of the coil spring S8, the peripheral portion of the lower sheet S4 can be easily brought into contact with one of the contact portions cn of the lower sheet receiving member 74 with good operability, and displacement can be prevented. Inclination of the upper side of the strut assembly S is reliably prevented.

At this time, the control means 16 holds the left and right spring locking bars 91 (see FIG. 2B), which are pin-coupled to the lower end frame portion of the strut mounting base 11, in the retreat position d1, and the operator lowers them. A coil spring S8 is fitted on the sheet S4.
Thereafter, when an assembly start command from the operator is input to the control means 16, the assembly operation is started.

First, when an assembly start command is received, as shown in FIG. 1, at that time, the strut mounting base 11 rotates, and the shock absorber clamping means 26 at the pre-assembly position K2 faces the assembly position K1.
At this time, the longitudinal center line L0 of the strut assembly assembling means 20 and the sandwiching center line La of the strut mounting base 11 are located on the same line.
Further, the cylinder 23 is turned on and is driven so that the upper end of the load receiving member 12 comes into contact with the lower wall of the lower receiving base 111. Accordingly, it is possible to prevent the lower pedestal 111 from being displaced up and down by a load at the time of subsequent spring compression.

Next, the control means 16 drives the strut assembly assembling means 20 along the spring compression process g1 to the compression return process g4.
First, the strut assembly assembly means 20 enters the spring compression step g1.
Here, the control means 16 turns on the opening drive means (not shown) and switches and holds the left and right spring locking bars 91 from the locking position d2 to the release position d1 against the elastic force of the plurality of springs 93. At this time, the pressurizing member 47 (see FIGS. 2A and 2B) protruding downward from the support frame 42 supported by the lower part of the movable body 6 via the left and right feed rails 43 and the front and rear feed rails 44 is moved downward. The coil spring S8 of the strut S held by the shock absorber clamping means 26 is compressed from the locking position B0 (see FIG. 9A) to the first compression position B1.

  At this time, as shown in FIG. 5, since the center line Lc of the coil spring S8 is inclined with respect to the clamping center line La and the longitudinal center line L0, the compression operation force F2 is applied in the direction of the clamping center line La. In addition to F3, a tilt direction component force F4 for tilting the strut is received. The tilt direction component force F4 received by the strut assembly S is received by one contact portion cn of the lower sheet receiving member 74 from the peripheral edge portion of the lower sheet S4. Thereby, even if it receives the inclination direction component force F4, the upper sheet | seat of the lower seat S4 and the strut assembly S before an assembly is prevented reliably.

When this compression process is completed, the control means 16 turns off the unillustrated opening drive means, and as shown in FIG. 2B, the left and right spring locking bars 91 are moved from the retracted position d1 by the elastic force of the plurality of springs 93. The movement is switched to the locking position d2, and the upper end of the compressed coil spring S8 is locked. Thereafter, the left and right pressure members 47 (see FIG. 9A) are returned from the first compression position B1 to the standby position B0.
Next, the drawing and upper sheet assembling step g2 is entered. First, the pulling device 46 (see FIG. 9B) of the movable support frame 42 that is supported by the left and right feed rails 43 and the front and rear feed rails 44 in the direction perpendicular to the paper surface is placed on the clamping center line La and the vertical center line L0. Switch.

The pulling device 46 includes a chuck 461 at the bottom, and clamps the upper end of the rod S5 when the chuck 461 is lowered by the lifting actuator 462. Thereafter, as the chuck 461 moves up, the rod S5 is pulled out from the strut 4 to a predetermined height. At this time, the pressing member 464 presses the upper end of the bump rubber rm to avoid the rise.
Next, the left and right feed rails 43 and the front and rear feed rails 44 are switched to switch the upper seat clamping device 48 (see FIG. 9C) on the clamping center line La and the longitudinal center line L0 instead of the pulling device 46. Hold. At this time, the upper sheet clamping device 48 chucks the upper sheet S6 by the gripping portion 481, and is disposed on the clamping center line La from the standby position (see the position indicated by the two-dot chain line in FIG. 9C). Next, by descending together with the upper sheet S6 from directly above S5, the hole at the center of the upper sheet S6 is fitted to the upper end of the rod S5.

Thereafter, the fastening process g3 is entered.
The control means 16 drives the left-right feed rail 43 and the front-rear feed rail 44, moves the front-rear feed rail 44 side to a predetermined retracted position, and then retreats the nut runner 9 (see FIGS. 1 and 9 (d)). The position H1 is moved downward from the position H1 to the fastening position H2 to drive the fastening. At this time, the nut S7 (see FIGS. 5 and 9D) is screwed to the threaded portion of the piston rod S5 of the strut assembly S, the upper seat S6 is fastened to the upper end of the rod 39, and is pulled up to the retracted position H1.
Thereafter, a compression return step g4 is started in which the coil spring S8 is simultaneously released from the left and right spring locking bars 227 of the left and right shock absorber clamping means 212 and 212 ′.

  Here, the control means 16 presses the pressure member 47 on the slide base 45 from the standby position B0 to the first compression position B1 to switch the coil spring S8 from the hook portion 912 of the left and right spring locking bar 91. . Further, after the left and right spring locking bar 91 is driven in the opening direction and retracted from the coil spring S8, the movable main body 6 is lifted and the pressure member 47 is lifted from the first compression position B1 to the second release position B2. The upper end of the coil spring S8 approaches the upper seat 204 by slightly raising it. Immediately after that, when the pressing member 47 moves in the opening direction, the upper end portion of the coil spring S8 comes off from the pressing member 47 and comes into contact with the upper sheet S6.

Thereafter, the control means 16 rotates the strut mounting base 11 by 180 ° so that the assembled strut assembly S faces the pre-assembly position K2.
At this time, the next pre-assembly strut has already been attached to the other shock absorber clamping means 26 of the strut mounting base 11, and the next assembly command is awaited.

  As described above, according to the strut assembly assembling apparatus M1 of FIG. 1, the peripheral portion of the lower sheet S4 of the strut assembly S is received by one abutting portion cn of the lower seat holder 74 prior to the compression process. Even if the center line Lc of the coil spring S8 is inclined with respect to the sandwiching center line La, and the compression operation force F2 generates an inclination direction component force F4 that inclines the struts, the upper portion of the lower seat S4 and the strut assembly S before assembly is provided. The side is reliably prevented from tilting. For this reason, when the upper end of the coil spring S8 is brought into contact with the upper seat S6, the piston rod S5 is reliably prevented from being inclined and held at an appropriate position. For this reason, the process of fitting the upper seat S6 and the insulator (not shown) into the top of the piston rod S5 and screwing the nut S7 onto the threaded portion, which is the subsequent assembly process, is facilitated and the upper end of the spring is brought into contact. The upper sheet S6 can be securely fastened to the upper end of the rod 39, and the assembly of the upper sheet S6 is facilitated.

  In particular, the ratchet mechanism portion of the shift restricting means 81 allows the lower sheet holder 74 to move toward the sandwiching center line La and easily prevents displacement in the direction perpendicular to the sandwiching center line La. During assembly of the spring S8, the peripheral edge portion of the lower sheet S4 can be easily brought into contact with one of the contact portions cn of the lower sheet receiving member 74 with good operability, and the lower sheet receiving member has a component force F11 in the inclination direction. The lower sheet holder 74 can be prevented from shifting in the switching direction D in conjunction with the reception.

  Furthermore, even if the lower seat holder 74 (lower seat support means) is pushed and moved so as to approach the clamping center line La, even if the strut assembly S has a different shape, it is placed on the periphery of each lower seat S4. One of a plurality of contact portions cn arranged in a staircase shape can be surely contacted, and the inclination of the strut assembly S can be easily prevented, and subsequent temporary assembly and nut fastening processing on the upper seat side can be performed easily and reliably. be able to.

  Further, the connecting rod 791 and the pressing slide member 792 used in the switching unit 78 form a link for applying a driving force in the switching direction D, and the air cylinder 79 forms a switching driving unit for transmitting the driving force to the link. This driving force can be transmitted to the lower sheet receiving member 74 via the link, and the work of bringing the contact portion cn of the lower sheet receiving member into contact with the peripheral portion of the lower sheet S4 is facilitated.

  As described above, in the turntable type strut assembly assembling apparatus to which the present invention is applied, in particular, the lower sheet receiving member 70 movably supported on the upper portion 100 of the strut mounting base 11 and the lower sheet receiving member 70 are provided. Equipped with the displacement restricting means 81 (see FIG. 3) capable of preventing the displacement in the switching direction D can easily prevent the inclination of the strut assembly S and ensure the subsequent temporary assembly and nut fastening process on the upper seat side. It is possible to reliably obtain the effect that it can be easily performed.

The right wheel strut 202 'is set in the absorber clamping means 212'. Next, the clamp arms 226 of the left and right shock absorber clamping means 212 and 212 'are closed. Next, the worker W places the coil spring S8 on the lower seat 207 of each strut 202, 202 ′. Further, the upper sheet 204 is placed on each of the upper sheet temporary placement stands 220 and 220 ', and the mount insulator rm is placed on each of the insulator temporary placement stands 221 and 221'.

  The left and right pair of spring compression means BM ′ provided on the first stage G1 has the same configuration on both the left and right sides, and the coil springs S8 of the struts 202 and 202 ′ held by the left and right shock absorber clamping means 212 and 212 ′. Each is compressed from above to a predetermined height. As shown in FIG. 9A, the spring compressing means BM ′ is configured such that the pressurizing member 47 positioned above the coil spring S8 lowers the pressurizing member 47 by the lifting actuator 232 (see FIG. 12). Each coil spring S8 is compressed by a predetermined amount.

  At this time, as described with reference to FIG. 5, the strut assembly S receives the inclination direction component force F4, which is received by the lower sheet receiving member 70 from the peripheral edge of the lower sheet S4. As a result, even if the component force F4 in the inclination direction is received, the inclination of the upper side of the lower seat S4 and the strut assemblies S1, S1 'before assembly is reliably prevented.

  When this compression process is completed, as shown by the solid line in FIG. 9A, the left and right spring locking bars 227 of the shock absorber holding means 212 and 212 ′ are closed, and the pressure member 47 is further raised to the standby position B0. Thereby, each coil spring S8 is hooked on the locking portion of the left and right spring locking bar 227 and is held in a compressed state.

  Next, the turntable 211 is rotated by 90 °. At this time, the upper sheet 204 on the upper sheet temporary placing tables 220 and 220 ′ (see FIG. 10) and the bump rubber rm on the insulator temporary placing tables 221 and 221 ′ are also first. Move to 2nd stage G2.
