Description
Technical Field
The present disclosure relates to a conveying device for a drive motor that rotationally drives an input shaft.
Background
In the automobile, various tests can be performed by connecting a drive motor for rotating an input shaft of a test piece to the input shaft and connecting an absorption motor for generating a load in a simulated manner during vehicle running to an output shaft of the test piece. Examples of the test pieces include a transmission (transaxle), an engine, a differential gear, a transfer (four-wheel drive component), and the like.
As an apparatus for performing the above test, for example, a transmission test apparatus disclosed in patent document 1 is known. Patent document 1 discloses a test apparatus in which a test piece is used as a transmission.
In order to perform the above test, the drive motor and the absorption motor need to be provided at predetermined positions, and therefore, a conveyance mechanism for the drive motor and a conveyance mechanism for the absorption motor are prepared separately.
Fig. 11 is an explanatory view schematically showing a conventional conveying mechanism for a drive motor and a conventional conveying mechanism for an absorption motor. The XYZ rectangular coordinate system is marked in fig. 11.
As shown in fig. 11, one drive motor 50 and two absorption motors 51 and 52 are used for the test of the test pieces.
Similarly, the hydraulic cylinder 62 performs a linear movement process of moving the absorption motor 52 in the movement direction D2 that coincides with the X direction by the expansion and contraction operation of the rod in the X direction.
The drive motor 50 is mounted on a mount 65 positioned in the drive motor installation range R50, and the mount 65 is provided on the pair of rails 71 so as to be linearly movable in the Y direction. The drive motor 50 is provided on the mount 65 so as to be rotatable about a rotation axis C50.
The mount 65 is provided with a hydraulic cylinder 60Y. The hydraulic cylinder 60Y can perform a linear movement process of moving the mount 65 provided on the pair of rails 71 in a movement direction DY that coincides with the Y direction by the telescopic movement of the rod in the Y direction. The driving motor 50 mounted on the stage 65 is also linearly moved at the same time by the movement of the stage 65.
The rod of the hydraulic cylinder 60C is connected to the vicinity of the center of the drive motor 50, and the extending and contracting directions of the rod are set to tilt directions having effective angles with respect to the X axis and the Y axis, respectively.
Therefore, the hydraulic cylinder 60C can perform the turning movement process of moving the drive motor 50 on the mount 65 in the turning direction DC about the turning rotation shaft C50 by the telescopic movement of the rod in the tilt direction.
By the combination of the turning movement process by the hydraulic cylinder 60C and the linear movement process by the hydraulic cylinder 60Y, the drive motor 50 can be moved to a desired position within the drive motor installation range R50, and the drive motor 50 can be set to a desired posture.
The desired posture is a state in which the rotation angle of the drive motor 50 with respect to the rotation axis C50 is set to a desired angle. Instead of the hydraulic cylinders 60C and 60Y, a ball screw may be used.

Disclosure of Invention
Problems to be solved by the invention
As a conveyance device for the conventional drive motor 50 shown in fig. 11, a combination of a hydraulic cylinder 60Y and a hydraulic cylinder 60C is used.
However, in the conventional transport device for the drive motor 50, the movement process performed by the hydraulic cylinder 60Y is limited to the linear movement in the Y direction, and the movement process performed by the hydraulic cylinder 60C is limited to the turning movement in the turning direction DC.
Therefore, in the conventional transport apparatus, the work of setting the drive motor 50 at a desired position in a desired posture within the drive motor setting range R50 takes a relatively long time, and there is a problem of poor work efficiency.
Further, since the conveyor device includes the frame 65 and the rail 71 in addition to the hydraulic cylinders 60C and 60Y, the area occupied by the equipment of the conveyor device is relatively large, and as a result, it is difficult to secure a working space when the operator operates the hydraulic cylinders 60C and 60Y.
The present disclosure has an object to provide a conveyor device for a drive motor, which solves the above-described problems, improves work efficiency, and facilitates the maintenance of a work space.
Means for solving the problems
The conveying device of the present disclosure is a conveying device for a drive motor that rotationally drives an input shaft, and includes: a motor mounting table on which the drive motor is mounted; and a floating base for supporting the motor mounting table from below, wherein an air transfer mechanism is configured to include the motor mounting table and the floating base, the floating base contains air casters, and the air transfer mechanism performs a floating operation for floating a transfer target object including the drive motor, the motor mounting table, and the floating base by supplying compressed air to the air casters.
Effects of the invention
The air conveyance mechanism in the conveyance device of the present disclosure performs a floating operation of floating a conveyance target object by a floating base in which air casters are housed.
Since the conveyance target is a structure in which the drive motor, the motor mounting table, and the floating base are stacked, the occupied area can be made relatively small. Therefore, the operator can easily secure a working space when moving the floating conveyance target.
In addition, when the floating operation by the air conveyance mechanism is performed, the conveyance object floats. Therefore, the operator can easily and accurately set the relatively heavy drive motor at a desired setting position, and therefore, the work efficiency required for setting the drive motor can be improved.
Since the air casters of the air conveyance mechanism are housed in the floating base, the vibration generated when the drive motor is used is received by the motor mounting table and the floating base (the area around the air casters other than the housing area of the air casters), and the air casters can be protected when the drive motor is used.
The objects, features, aspects and advantages of the present disclosure will become more apparent from the following detailed description and the appended drawings.

Detailed Description
< embodiment >
(air conveying mechanism 1)
Fig. 1 is an explanatory diagram schematically showing the configuration of an air conveyance mechanism 1 as a main component of the conveyance device of the present embodiment. The conveying device of the present embodiment is a conveying device for driving the motor 50.
As shown in fig. 1, the air transfer mechanism 1 includes a float base (float base)2 and a mount 5 as main components.
The mount 5 functions as a motor mounting table on which the drive motor 50 is mounted. The floating base 2 supports the mount 5 from below.
The floating base 2 accommodates an air caster 3 (not shown in fig. 1) therein. Therefore, the air conveyance mechanism 1 can perform a floating operation of floating the conveyance object including the drive motor 50, the gantry 5, and the floating base 2 by supplying compressed air to the air casters 3. Fig. 1 shows a state where the object to be conveyed floats from the ground surface 8.
Fig. 2 is an explanatory view schematically showing a conveying mechanism for a drive motor and a conveying mechanism for an absorption motor in the present embodiment. The XYZ rectangular coordinate system is marked in fig. 2.
As shown in fig. 2, one driving motor 50, two absorption motors 51 and 52 are used for the test of the test pieces.
The hydraulic cylinders 61 and 62 are provided corresponding to the absorption motors 51 and 52 in the same manner as in the conventional art. The hydraulic cylinder 61 performs a linear movement process of moving the absorption motor 51 in the movement direction D1 by the expansion and contraction operation of the rod.
Similarly, the hydraulic cylinder 62 performs a linear movement process of moving the absorption motor 52 in the movement direction D2 by the expansion and contraction operation of the rod.
Since the absorption motors 51 and 52 can be installed only by linear movement in the X direction, the hydraulic cylinders 61 and 62 are used as the conveyance mechanisms for the absorption motors 51 and 52 as in the conventional case.
On the other hand, the conveying device for the drive motor 50 of the present embodiment includes the air conveying mechanism 1 shown in fig. 1 as a main component. As shown in fig. 1, the air conveyance mechanism 1 is present directly below the drive motor 50, and therefore, illustration thereof is omitted in fig. 2.
As shown in fig. 2, the installation position of the drive motor 50 is set within a drive motor installation range R50, which is a predetermined installation range.
Since the conveyance target object including the drive motor 50 floats by the floating operation of the air conveyance mechanism 1, the operator can relatively easily move the conveyance target object in any direction. As a result, the operator can easily and highly accurately place the conveyance target object within the drive motor installation range R50. The moving direction D0 shown in fig. 2 shows an example of the moving direction.
Fig. 3 is an explanatory diagram showing a detailed configuration of the air conveyance mechanism 1. Fig. 4 is a plan view schematically showing the arrangement state of the four air casters 3 in the floating base 2. The XYZ rectangular coordinate system is shown in fig. 3 and 4.
As shown in fig. 3, a mount 5 is provided on the floating base 2. The mount 5 as a motor table has an upper surface on which the drive motor 50 is mounted.
The driving motor 50 is a device that rotates at a high speed at about 6000 to 15000 revolutions per 1 minute. Therefore, when the drive motor 50 is directly provided on the air caster 3, vibration is generated in the air caster 3 by the high-speed rotation of the drive motor 50, and there is a possibility that the air caster 3 is adversely affected.
Therefore, the air conveyance mechanism 1 of the present embodiment accommodates the air caster 3 in the floating base 2, and sandwiches the mount 5 between the floating base 2 and the drive motor 50.
As a constituent material of the mount 5, a material having high rigidity and relatively light weight is preferable. The reason for increasing the rigidity is to suppress vibration generated by high-speed rotation of the drive motor 50. The reason why the relatively light material is used is to improve the work efficiency of the moving process of the object to be conveyed including the drive motor 50, because the gantry 5 itself is also included in the object to be conveyed.
As shown in fig. 4, the floating base 2 is rectangular in plan view, and four air casters 3A to 3D are disposed at four corners corresponding to the four corners in the floating base 2. Since the internal configurations of the air casters 3A to 3D are the same, the following description will be made only as "air caster 3" when the air casters 3A to 3D are collectively referred to.
In this way, the floating base 2 accommodates the air caster 3 therein. In the floating base 2, a material having relatively high rigidity is used in the air caster peripheral area 2P excluding the accommodation area of the air caster 3. Thus, the air caster 3 accommodated in the floating base 2 is protected by the air caster peripheral area 2P.
As shown in fig. 3, the air caster 3 includes a base plate 31 and a bag (bag)32 having an annular shape in a downward plan view of the base plate 31. A central region surrounded by the bag 32 below the substrate 31 serves as an air supply region 33. Compressed air is supplied from the air supply port 21 to the air supply area 33 through an air supply pipe 22 as an external air pipe and a passage (not shown) in the substrate 31.
When the internal pressure of the air supply area 33 rises to support and lift the object to be conveyed, the air conveyance mechanism 1 can perform a floating operation in which the air is floated with the drive motor 50 placed thereon on each air caster 3.
In this way, the air conveyance mechanism 1 of the embodiment performs a floating operation of floating the conveyance object by the floating base 2 in which the air casters 3 are housed.
Since the object to be conveyed is a structure in which the drive motor 50, the gantry 5, and the floating base 2 are stacked, the occupied area can be made relatively small. Therefore, the operator can relatively easily secure a working space when moving the floating conveyance target.
In addition, when the floating operation by the air conveyance mechanism 1 is performed, the conveyance target object floats. Therefore, the operator can easily and highly accurately set the relatively heavy drive motor 50 at a desired setting position, and therefore, the work efficiency required for setting the drive motor can be improved.
The air conveyance mechanism 1 further includes a mount 5 as a motor mounting table between the drive motor 50 and the floating base 2. Therefore, vibration that may be generated in the air caster 3 during operation of the drive motor 50 is absorbed by the air caster peripheral region 2P of the floating base 2 and the mount 5, and the air caster 3 in the floating base 2 can be protected during use of the drive motor 50.
Therefore, the floating operation of the air conveyance mechanism 1 is not hindered even after the use of the drive motor 50. During the operation of the drive motor 50, the air conveyance mechanism 1 is not floated, but is placed on the floor surface 8.
Fig. 5 and 6 are explanatory views showing an example of the test apparatus after the drive motor 50 and the absorption motors 51 and 52 are installed.
As shown in these figures, the drive motor 50 is coupled to an input shaft 80 of a transmission/transaxle 70 as a test piece, and absorption motors 51 and 52 are coupled to both ends of an output shaft 85 of the transmission/transaxle 70.
As shown in fig. 6, the drive motor 50 is mounted on the mount 5 of the air conveyance mechanism 1. After the driving motor 50 is installed, the air conveyance mechanism 1 stops the floating operation, and the floating base 2 is installed on the floor surface 8.
As shown in fig. 6, the absorption motor 51 is mounted on a mount 63, and the absorption motor 52 is mounted on a mount 64. A cover 50c is provided at a part of the drive motor 50.
As shown in fig. 5 and 6, the drive motor 50 is set at a desired position by the air conveyance mechanism 1, and the absorption motors 51 and 52 are set at desired positions by the hydraulic cylinders 61 and 62, thereby constituting a test apparatus for the transmission/transaxle 70.
(pressure adjusting function)
Fig. 7 and 8 are explanatory views showing a pressure adjusting function of the air caster 3 included in the air conveyance mechanism 1 according to the embodiment. Fig. 7 is an explanatory view showing the structure of the pressure adjustment panel 10 and the periphery thereof, and fig. 8 is an explanatory view schematically showing a pressure adjustment system for the air casters 3A to 3D.
As shown in these figures, compressed air supplied from an external air supply port 21 is branched at the pressure reducing valves 12A to 12D via the pressure reducing valve 11 and an air supply pipe 22 (external air pipe) and supplied to the air supply pipes 22A to 22D.
The pressure reducing valve 12A, the pressure gauge 13A, and the check valve 14A are provided corresponding to the air supply pipe 22A. The pressure reducing valve 12B, the pressure gauge 13B, and the check valve 14B are provided corresponding to the air supply pipe 22B.
The pressure reducing valve 12C, the pressure gauge 13C, and the check valve 14C are provided corresponding to the air supply pipe 22C. The pressure reducing valve 12D, the pressure gauge 13D, and the check valve 14D are provided corresponding to the air supply pipe 22D.
As shown in fig. 7, the pressure reducing valve 11, the air supply pipe 22, the pressure reducing valves 12A to 12D, the pressure gauges 13A to 13D, and the check valves 14A to 14D are collectively provided in the pressure adjustment panel 10, and the air supply port 21 is disposed in the vicinity of the pressure adjustment panel 10.
As described above, the floating base 2 has the air casters 3A to 3D as the first to fourth air casters arranged at four corners inside.
The floating base 2 further includes air supply pipes 22A to 22D as first to fourth air supply pipes.
In addition, the air transport mechanism 1 includes pressure gauges 13A to 13D as first to fourth pressure gauges, pressure reducing valves 12A to 12D as first to fourth pressure regulators, and check valves 14A to 14D.
The air supply pipes 22A to 22D are provided independently of the air casters 3A to 3D, respectively. As described above, the pressure reducing valves 12A to 12D, the pressure gauges 13A to 13D, and the check valves 14A to 14D are provided corresponding to the air supply pipes 22A to 22D.
The air supply pipe 22A (first air supply pipe) is a pipe for sending compressed air to the air caster 3A (first air caster), and the air supply pipe 22B (second air supply pipe) is a pipe for sending compressed air to the air caster 3B (second air caster). The air supply pipe 22C (third air supply pipe) is a pipe for sending compressed air to the air caster 3C (third air caster), and the air supply pipe 22D (fourth air supply pipe) is a pipe for sending compressed air to the air caster 3D (fourth air caster). The air supply pipes 22A to 22D are provided independently of each other.
That is, the ith (i is any one of one to four) air supply pipe is a pipe for separately sending compressed air to the ith air caster.
The pressure gauge 13A (first pressure gauge) measures a first air supply pressure that is the pressure in the air supply pipe 22A, and the pressure gauge 13B (second pressure gauge) measures a second air supply pressure that is the pressure in the air supply pipe 22B. The pressure gauge 13C (third pressure gauge) measures a third air supply pressure that is a pressure in the air supply pipe 22C, and the pressure gauge 13D (fourth pressure gauge) measures a fourth air supply pressure that is a pressure in the air supply pipe 22D.
That is, the ith pressure gauge measures the ith air supply pressure, which is the pressure in the ith air supply pipe.
The pressure reducing valve 11 is a valve for reducing the pressure of the compressed air supplied from the air supply port 21 and maintaining the pressure of the air supply pipe 22 after the pressure reduction at a constant level.
The pressure reducing valves 12A to 12D are valves for reducing the pressure in the air supply pipe 22 and maintaining the pressure in the air supply pipes 22A to 22D after the pressure reduction at a constant level. The check valves 14A to 14D are valves for preventing reverse flow of compressed air.
Therefore, the first air supply pressure in the air supply pipe 22A can be adjusted individually by operating the pressure reducing valve 12A (first pressure regulator), and the second air supply pressure in the air supply pipe 22B can be adjusted individually by operating the pressure reducing valve 12B (second pressure regulator).
Similarly, the third air supply pressure in the air supply pipe 22C can be independently adjusted by operating the pressure reducing valve 12C (third pressure regulator), and the fourth air supply pressure in the air supply pipe 22D can be independently adjusted by operating the pressure reducing valve 12D (fourth pressure regulator).
That is, since the air supply pipes 22A to 22D are arranged independently of each other, the ith pressure regulator can individually regulate the ith air supply pressure in the ith air supply pipe.
As described above, the air transport mechanism 1 of the embodiment has a pressure adjusting function capable of individually adjusting the first to fourth air supply pressures in the air supply pipes 22A to 22D by the first to fourth pressure adjusters (the pressure reducing valves 12A to 12D). The first to fourth air supply pressures can be known from the measurement values of the pressure gauges 13A to 13D.
The air transport mechanism 1 of the present embodiment has the above-described pressure adjustment function. Therefore, the operator can set the internal pressure of the compressed air of each of the air casters 3A to 3D so that the conveyance target object floats in a balanced manner by referring to the measurement values of the pressure gauges 13A to 13D in consideration of the center of gravity of the drive motor 50 and the like and by individually adjusting the first to fourth air supply pressures by the pressure reducing valves 12A to 12D.
As a result, the conveying device (air conveying mechanism 1) of the present embodiment can float the conveying object including the relatively heavy drive motor 50 with good balance, and accordingly, the work efficiency required for installing the drive motor 50 can be further improved.
(Crane 4)
Fig. 9 and 10 are explanatory views showing the structure of the crane 4. Fig. 9 is a plan view and fig. 10 is a side view. The XYZ rectangular coordinate system is shown in fig. 9 and 10.
As shown in these figures, the crane 4 serving as the supply member holding mechanism holds a wiring group 45 and a pipe 46, the wiring group 45 including a power supply wiring and a drive signal line for supplying a drive power to the air caster 3, and the pipe 46 including an air supply pipe 22 serving as an external air pipe for supplying compressed air to the air caster 3. These wiring group 45 and piping 46 serve as supply members for air casters, the wiring group 45 serves as a first supply member, and the piping 46 serves as a second supply member.
As shown in fig. 10, the operator can move the conveyance object 55 while holding the pair of handles 75 in a state where the conveyance object 55 is floating, and can set the conveyance object 55 at a desired position in a desired posture within a drive motor setting range R50 (predetermined setting range). Here, the posture refers to the arrangement of the horizontal plane of the drive motor 50 (the position of the connection portion with respect to the input shaft of the test piece, etc.).
The crane 4 includes a column 41, a rotation mechanism 42, and a wiring/piping rack 43 as main components.
The support column 41 is fixed to the floor surface 8 outside the drive motor installation range R50, and the rotation mechanism 42 is installed upright on the support column 41 and can be driven to rotate.
The wiring/piping rack 43 (wiring rack 43a + piping rack 43b) is provided above the rotation mechanism 42, and a wiring group 45 and a piping 46 as supply members for air casters are accommodated along a horizontal plane defined by an XY plane.
The wiring/piping rack 43 serving as the supply member housing rack includes a wiring rack 43a and a piping rack 43 b.
An end of the wiring frame 43a is connected to the top of the rotation mechanism 42, and the piping frame 43b is connected to the lower side of the wiring frame 43a by a connecting member 49.
The wiring rack 43a as a first housing rack has a wiring housing area 431 as a first housing area for housing a part of the wiring group 45 as a first supply member along a horizontal plane defined by an XY plane.
The pipe rack 43b as the second housing rack has a pipe housing area 432 as a second housing area for housing a part of the pipe 46 as the second supply member along a horizontal plane defined by the XY plane.
The wiring rack 43a and the piping rack 43b are both disposed at a position higher than the conveyance object 55 floated by the air conveyance mechanism 1. The wiring accommodation area 431 and the pipe accommodation area 432 are provided at a height not overlapping each other.
In the wiring rack 43a as the first housing rack, a part of the wiring group 45 is housed in the wiring housing area 431, and one end (the Y side) is drawn out of the wiring housing area 431 and extended downward to be connected to the air caster 3. Note that the connection between the wiring group 45 and the air caster 3 is not shown in fig. 10.
In the pipe rack 43b, a part of the pipe 46 is accommodated in the pipe accommodation area 432, and one end (the (-Y side) is drawn out of the pipe accommodation area 432, extended in a downward direction, and finally connected to the air caster 3. The connection between the pipe 46 and the air caster 3 is not shown in fig. 10.
That is, the wiring/piping rack 43 is provided above the rotation mechanism 42, and has an accommodation region (wiring accommodation region 431+ piping accommodation region 432) for accommodating the air caster supply member (wiring group 45 and piping 46) along the horizontal plane.
The air caster supply member (the wiring group 45 and the pipes 46) is partially housed in the housing area, has one end drawn out of the housing area, and extends in a downward direction to be connected to the air caster 3.
In such a configuration, the crane 4 performs the rotation operation of the wiring/piping rack 43 in the rotation direction D4 with the rotation mechanism 42 as the rotation axis by the rotation driving of the rotation mechanism 42. By this rotation operation, a movement operation for a work in which the wiring group 45 and one end of the pipe 46 are moved in an installation range overlapping region overlapping with the drive motor installation range R50 in a plan view can be performed.
As shown in fig. 10, the wiring housing area 431 and the piping housing area 432 are provided at a height not overlapping each other, and perform a rotation operation simultaneously for the wiring rack 43a and the piping rack 43 b.
In this case, the wiring rack 43a and the piping rack 43b accommodate the wiring group 45 and the piping 46 such that one ends of the wiring group 45 and the piping 46 do not overlap in a plan view during the execution of the rotation operation. Specifically, as shown in fig. 10, the lengths of the wiring rack 43a and the piping rack 43b in the Y direction are set to be different lengths, and the position on the Y coordinate of one end of the wiring group 45 and the position on the Y coordinate of one end of the piping 46 are set to have an effective interval so that the wiring group 45 and the piping 46 do not contact each other during the rotation operation.
The conveying device of the present embodiment includes a crane 4 as a supply member holding mechanism in addition to the air conveying mechanism 1. The crane 4 accommodates most of the wiring group 45 and the pipes 46 above the conveyance target object 55 by the wiring/piping rack 43 (wiring rack 43a + piping rack 43b) provided at a position higher than the lifted conveyance target object 55.
Therefore, when the operator performs a movement process such as turning movement of the object 55, the possibility that the wiring group 45 and the pipes 46 become obstacles can be greatly reduced. Therefore, the operator can smoothly move the conveyance target 55 without being affected by the piping group 45 and the piping 46.
In the crane 4, the rotation operation along the rotation direction D4 of the wiring/piping rack 43 includes a movement operation at the time of an operation of moving one end of the wiring group 45 and the piping 46 in an installation range overlapping region overlapping with the drive motor installation range R50 (predetermined installation range) in a plan view.
Therefore, the operator can move the floating conveyance target 55 while performing the operation of the wiring/piping rack 43, and can sequentially set the positions of the wiring group 45 and one end of the piping 46 so as to be suitable for the movement state of the conveyance target 55.
As a result, the operator can easily and accurately perform relatively complicated movement such as turning movement of the transport object 55 without adversely affecting the wiring group 45 and the pipes 46, and accordingly, the operation efficiency can be further improved.
As an adverse effect on the wiring group 45 and the pipe 46, for example, disconnection of the power supply wiring and the signal line in the wiring group 45, and detachment of the pipe 46 are conceivable.
In addition, the crane 4 accommodates the wiring group 45 in the wiring rack 43a as a first accommodation rack and accommodates the pipes 46 in the pipe rack 43b as a second accommodation rack, thereby accommodating the wiring group 45 and the pipes 46 so as to be separated from each other.
Therefore, the crane 4 in the transport apparatus of the present embodiment can accommodate the wiring group 45 and the pipe 46 so that the wiring group 45 and the pipe 46 do not contact each other.
The wiring rack 43a and the piping rack 43b in the crane 4 of the transport apparatus according to the present embodiment accommodate the wiring group 45 and the piping 46 such that one ends of the wiring group 45 and the piping 46 do not overlap in a plan view during the execution of the rotation operation.
Therefore, the transport apparatus according to the present embodiment separates the wiring group 45 and the pipes 46 even during the rotation operation of the wiring/piping rack 43, and reliably prevents the possibility of the wiring group 45 and the pipes 46 coming into contact with each other.
Therefore, the operator can move the conveyance target 55 without causing adverse effects due to the contact between the line group 45 and the line 46, and accordingly, the operation efficiency can be further improved.
In addition, the present disclosure may be modified and omitted as appropriate within the scope of the disclosure.
