[Prior art]

 FIG. 11 is a plan view showing a conventional configuration of a jig used for aligning a work and a push-pull device conventionally used in a construction site or the like. A jig used for aligning the conventional work with the push-pull device will be described below with reference to FIG.

The push-pull device 2 is provided with two pins 6 at two positions on the upper surface of the arm 2e, and the work 1 has a diameter slightly larger than that of the pins 6, and the two pins 6 are provided. There were two pin holes 7 that fit together. The pin 6 and the pin hole 7 functioned as a jig used for aligning the work with the push-pull device. That is, the work 1 is installed on the upper surface of the arm 2e with the two pins 6 aligned with the pin holes 7, respectively, so that the push-pull device 2 and the work 1 before the operation are aligned with each other. The push-pull device 2 was pushing and pulling the work 1 in the direction of the arrow X in the figure.

[0004]

[Problems to be solved by the device]

 In the conventional jig used for aligning the work and the push-pull device, when the work 1 is installed on the arm 2e, the pin hole 7 is enlarged so that the pin 6 and the pin hole 7 can be easily aligned. The position of the work 1 after the operation becomes difficult to determine in the Y arrow direction in the figure. If the push-pull device 2 and the work 1 are misaligned, the push-pull device may not function. On the other hand, if the pin hole 7 is too small, the positional accuracy of the work 1 after movement is maintained, but it becomes difficult to adjust the position when the work 1 is installed on the arm 2e.

An object of the present invention is to provide a jig used for aligning a work and a push-pull device suitable for solving such a problem.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the invention according to claim 1 is provided with a work and a push-pull device for pushing and pulling the work, and is used for aligning the work and the push-pull device. The push-pull device is provided with an engaging member having at least a pair of sides inclined at a predetermined angle with respect to the operation line, and the work piece to be engaged engages with the engaging member. The present invention relates to a jig used for aligning a work and a push-pull device, which is characterized in that

In addition, in the jig, the push-pull device has an arm, and an engaging member having an engaging surface having a flat V-shape is provided on an upper surface of the arm to draw an operation line of the push-pull device. Are provided with the corners of the "U" -shaped engaging surface facing in the direction, and these "" are engaged with the work member so as to engage with the engaging member having the "U" -shaped engaging surface. It is preferable to provide an engaged piece having an engaging surface having a V shape facing the engaging surface having a V shape.

Further, in the jig, the push-pull device includes a cylinder device for performing a push-pull operation and a tilt cylinder device for vertically moving an engaging member thereof, and an engaged member provided on a work is provided. The pieces may be arranged so that the engaging member is engaged and disengaged by the vertical movement of the engaging member.

[0009]

According to the jig of this invention, when the engaged piece of the work is engaged with both sides of the pair of engaging members of the push-pull device, the push-pull device pushes or pulls. By doing, the work is pushed or pulled on the operation line of the push-pull device as it is. On the other hand, when only one of both sides forming a pair of the engaging member of the push-pull device engages with the engaged piece of the work, the sides of the engaged engaging member and the engaged piece are the same as described above. Since it is tilted with respect to the operating line, slippage occurs between the sides of the engaging member and the engaged piece until both sides of the pair engage with the engaging side of the workpiece. The work moves with respect to the member. Therefore, the work is moved in a combined direction of the line of motion by the push-pull device and the left-right direction intersecting with the line, is arranged on the line of motion, and is pushed or pulled to a predetermined position on the line of motion in this state. Therefore, the position where the work is pushed or pulled is a predetermined position both in the direction of the operation line by the push-pull device and in the left-right direction relative thereto.

In addition, in the case where the engagement member of the push-pull device is provided with a flat “V” shaped engaging surface and the engaged piece of the work is provided with a “V” shaped engaged surface. Since the engaging surfaces and the engaged surfaces, which are opposite to each other, are engaged with each other, the space between the engaging surface and the engaged surface due to the pushing or pulling operation by the push-pull device. After the mating of the mating member and the mating piece is completed, the work and the push-pull device are not locked. The positions of and are securely fixed.

Further, when the engaging member is moved up and down by the tilt cylinder device, the engaging member is easily engaged with and disengaged from the engaged piece of the work, and the push-pull operation is facilitated. .

【Example】

 The present invention will be described below based on the embodiments shown in the drawings. 1 to 6 show a first embodiment to which the present invention is applied, in which FIG. 1 and FIG. 2 show one mode of use of the present invention. In the figure, 2 is a push-pull device, which is a cylinder device 2a fixed to the body of a building under construction, which is omitted in the figure, an advancing / retreating member 2b fixed to the tip of its piston rod, and this advancing / retreating member. A tilt installed between two arms 2e pivotally attached to a bracket 2c fixed to 2b by a shaft 2d, a bracket 2f below the advancing / retreating member 2b and a bracket 2g on the lower surface of the arm 2e by shafts 2h and 2i. It is composed of a cylinder 2 j, constitutes a three-joint link mechanism between the shafts 2d, 2h, 2i, and an engaging member 3 is fixed to the upper surface of the arm 2e. The two arms 2e are connected to each other by a connecting member (not shown) so that both arms 2e integrally rotate about the shaft 2d. The bracket 2g may be fixed to the connecting member (not shown). Further, the advancing / retreating member 2b may be configured to be guided by a guide device (not shown) in the extension / contraction direction of the cylinder device 2a.

The engaging member 3 is made of a plane "V" -shaped member, and thus has "U" -shaped engaging surfaces 3a, 3b, 3c, 3d on both the inside and the outside thereof which are bent. This "V" shape is provided with the corners of the "U" shaped engagement surface facing the direction of contraction of the cylinder device 2a, and the angle of the slope that is each engagement surface is the "U" shaped apex. The both sides make the same angle. More specifically, in this embodiment, each of the engaging surfaces, that is, the slanted surface, has an angle of 45 degrees with respect to the expansion and contraction direction of the cylinder device 2a. The angle is 90 degrees. However, this angle may be acute or obtuse.

In FIG. 1, reference numeral 1 denotes a work that is moved forward and backward by the push-pull device 2, and in this embodiment, a trolley on which materials used for building construction are mounted. The work 1 comprises a base 1a, casters 1b for freely moving the base 1a, and rising portions 1c at both ends of the base 1a, and two concave portions 1d are formed on the bottom surface of the base 1a. Thus, the engaged piece 4 is provided on each of them.

The engaged piece 4 faces the “U” -shaped engaging surface of the engaging member 3 so as to engage with the engaging member 3, which is also a “U” -shaped member. It has an engaged surface. The engaged piece 4 also has engaging surfaces 4a, 4b, 4c, 4d on both the inside and the outside that are bent, and its corners are directed in the same direction as the engaging member 3 and both sides of the corners are engaged. The angle of the slanted surface, which is each engaging surface, is also the same as that of the engaging member. Further, the engaged piece 4 of this embodiment has a length of its engaging surface larger than that of the engaging member 3. In this embodiment, the engaged piece 4 is formed in the recess 1d on the lower surface of the base 1a of the work 1, but it is directly formed on the bottom surface of the base 1a without forming the recess 1d. Of course, it is also good.

The work 1 is mounted on a lifting table 5 in FIG. The lift 5 is a lift in a temporary lift device for building construction. Next, the operation of this embodiment will be described. First, the operation of mounting the work 1 on the lift 5 from the floor of a certain floor will be described. First, the worker moves the work 1 to a position on the floor that faces the lifting table 5, and in this state, inserts the arm 2e of the push-pull device 2 into the lower surface of the table 1a of the work 1. At this time, the tilt cylinder device 2j is contracted so that the arm 2e is pivoted slightly downward, and the cylinder device 2a is extended in this state, so that the cylinder device 2a moves beyond the lift table 5 and moves the table of the work 1. It is inserted between 1a and the floor. After that, when the tilt cylinder 2j is extended and the arm 2e is swung upward, the engaging member 3 on the arm 2e rises and is inserted into the triangle formed by the engaged piece 4 of the work 1. .

When the cylinder device 2 a is contracted here, first, the engagement surface 3 a forming one of the refraction outside sides of the engagement member 3 forms one of the refraction inside side of the engaged piece 4. It hits the engaging surface 4a (FIG. 3). Next, when the cylinder device 2a continues to be reduced, slippage occurs between the abutting engagement surfaces 3a and 4a, and the work 1 is moved in the left-right direction with respect to the advancing and retracting direction of the cylinder device 2a, that is, in the engaging member 3. While moving in the pressing direction by the contacted surface 3a, the engaging member 3 moves toward the refracting apex of the engaged piece 4 so that both engaging surfaces 4a and 4b on the inside of the refracting side of the engaged piece 4 are Both engaging surfaces 3a, 3b on the non-refraction side of the engaging member 3 come into contact. Up to now, the work 1 has a combined movement in the pulling direction and the left and right directions due to the pulling by the cylinder device 2a and the lateral guide by the engaging surface.

After the engaging surfaces 4 a and 4 b on the inside of the refraction of the engaged piece 4 come into contact with the engaging surfaces 3 a and 3 b on the outside of the refraction of the engaging member 3, the engaging member 3 and Since the work piece 1 moves integrally with the engaged piece 4, the work piece 1 is moved in the pulling direction by the cylinder device 2a (FIG. 4). When there is no deviation between the push-pull device 2 and the work 1 in the left-right direction with respect to the expansion / contraction direction of the cylinder device 2a from the beginning, the work 1 moves from the beginning in the pulling direction by the push-pull device 2.

Thus, the cylinder device 2a determines the position of the work 1 in the pulling direction, and the engaging member 3 and the engaged piece 4 determine the position in the left-right direction with respect to the pulling direction. Therefore, the work 1 is accurately placed at a predetermined position on the lift table 5. After mounting the work 1 at this position, the tilt cylinder 2j is slightly contracted to disengage the engaging member 3 from the engaged piece 4, and then the cylinder device 2a is contracted to move the arm 2e to the work 1. It suffices to pull it out from between the lift table 5.

5 and 6 show a state in which the work 1 is pushed out from above the lifting platform 5 onto the floor, contrary to the above-mentioned FIGS. 3 and 4, and in this case, the engagement member 3 has a " This is performed by engaging the engaging surfaces 3c, 3d on the inside of the V-shaped refraction with the engaging surfaces 4c, 4d on the outside of the V-shape of the engaged piece 4 and extending the cylinder device 2a. Next, FIGS. 7 to 10 show a second embodiment to which the present invention is applied.

In this embodiment, the shapes of the engaging member 3 and the engaged piece 4 of the first embodiment are changed. That is, the engaging member 3 is made of a flat square solid member, and has two engaging surfaces 3a and 3b used for pulling on the cylinder device 2a side and two engaging surfaces 3c used for pushing on the opposite side. 3d, and the two engaging surfaces on both sides are symmetrical with respect to the expansion / contraction direction of the cylinder device 2a. Further, the engaged piece 4 has a square hole inside, and is formed on the inner surface on the cylinder device 2a side and two engaging surfaces 4a, 4b used for pulling and on the inner surface on the opposite side. It has two engaging surfaces 4c and 4d used at the time of pushing out, and each two engaging surfaces on the pulling side and the pushing side are also symmetric with respect to the extension / contraction direction of the cylinder device 2a. .

In either case of pushing or pulling, after the engaging member 3 is inserted into the hollow portion surrounded by the four engaging surfaces of the engaged piece 4, the cylinder device 2a is expanded or contracted. It will be small. In this case, at the time of pulling, the two engaging surfaces 3a and 3b of the engaging member 3 on the cylinder device 2a side and the two engaging surfaces of the engaging member 3 on the cylinder device 2a side of the engaged piece 4 are engaged. The position of the work 1 is determined by the two engagement surfaces 4a and 4b facing each other. FIG. 7 shows the initial state of engagement of the engagement member 3 with the engaged piece 4, and FIG. 8 shows the state at the end of the pulling operation. Further, at the time of pushing out, the two engaging surfaces 3c and 3d of the engaging member 3 on the side farther from the cylinder device 2a and the two engaging faces of the engaged piece 3 facing the cylinder device 2a side farther from the cylinder device 2a. The position of the work 1 is determined by the mating surfaces 4c and 4d. FIG. 9 shows an initial state in which the engaging member 3 is engaged with the engaged piece 4 at the time of pushing out, and FIG. 10 shows a state at the end of the pushing operation. The relationship and operation of the facing engagement surfaces at the time of pushing and pulling are the same as those in the first embodiment, and other configurations and actions are also the same as in the first embodiment.

[Effect of device]

 As described above, according to the present invention, in the jig used for aligning the work and the push-pull device, the push-pull device has at least a pair of sides arranged at a predetermined angle with respect to the operation line. By providing the engagement member and the engaged piece that engages with the engagement member on the work, the push-pull device is pushed and pulled before the operation so that the push-pull device exerts its function. The position of the work and the work can be easily aligned, and the positional relationship between the work and the push-pull device can be maintained even after the operation.

Further, even if the position of the work and the push-pull device is largely deviated before the operation, the work can be accurately placed in the correct position of the push-pull device after the operation. The above effect is particularly useful when the work must be manually aligned, or when the work is shaking or vibrating.

In addition, the engaging member is formed into a flat V-shape with its corners oriented in the direction of pulling the operating line of the push-pull device, and the engaged piece engages with the engaging member. The same effect as above can be obtained by using the pair arranged at, and the position of the work can be more easily fixed. The provision of the cylinder device and the tilt cylinder device facilitates the engagement and disengagement of the engagement member and the engaged piece. This makes it even easier to align the position of the push-pull device before operation with the work to be pushed and pulled, and remove the work from the push-pull device while maintaining the positional relationship between the work and the push-pull device after operation.
