Description

  The present invention relates to a holding device for holding engine-related parts when an engine is assembled.

  When an engine is assembled, an engine-related component such as an engine block may be held by a holding device, and the engine-related component may be suspended and transported together with the holding device. For example, as shown in FIG. 6 of Patent Document 1, the holding device has a pair of gripping members whose central portions are rotatably connected and intersected. The pair of gripping members change the distance between the lower end portions when the upper end portions are close to and away from each other, and hold the engine block between the lower end portions (scissors type).

  Or as shown in FIGS. 1-4 of patent document 1, it has a pair of cylindrical member inserted in each bore | bore of an engine block, and the nail | claw member provided in the lower side of a cylindrical member so that it can protrude and retract. When the cylindrical member extends through the bore, the claw member is extended from the lower end surface of the engine block, whereby the engine block is lifted from the lower side by the claw member (intrusion claw type).

  However, the scissor-type holding device needs to consider the holding angle at which the holding member comes into contact with the holding object because the gripping member moves in an arc shape. Therefore, it is not excellent in versatility. The nail type holding device is not excellent in versatility because it can hold only objects having holes. Then, this invention makes it a subject to provide the engine related component holding device which can be excellent in versatility.

  In order to solve the above-mentioned problems, the present invention is an engine-related component holding device having a configuration as described in each claim. According to the first aspect of the present invention, the apparatus main body, the pair of holding members provided in the apparatus main body, and the operation mechanism for changing the interval between the pair of holding members are provided. At least one of the holding members is attached to the apparatus main body so as to be linearly movable. The holding member is linearly moved with respect to the apparatus main body by the operation mechanism, whereby the distance between the pair of holding members changes linearly, and the pair of holding members cooperate to hold the engine-related parts.

  Therefore, the holding member moves linearly with respect to the apparatus main body to hold the engine-related parts linearly. Therefore, since the holding member does not need to consider the holding angle with respect to the engine-related component, it is possible to hold the engine-related component of another size only by changing the movement amount of the holding member. The holding device holds the engine-related component by a linear distance change between the pair of holding members. Therefore, engine-related parts and the like that do not have holes can be held. Thus, it is excellent in versatility. Further, since the holding member moves with respect to the apparatus main body, the moving part is smaller than in the case where the entire apparatus moves as in the conventional scissor type, and the holding apparatus can be downsized.

  According to the second aspect of the present invention, the positioning member that is provided on the apparatus main body and is positioned on the engine-related part so as to position the apparatus main body with respect to the engine-related part, and the apparatus main body linearly extends in a substantially horizontal direction. A pair of holding members that are movably attached and a lock mechanism that locks the pair of holding members with respect to the apparatus main body at a holding position where engine-related parts are held.

  Therefore, the apparatus main body can be positioned on the engine-related component by the positioning member. And a pair of holding member can be moved, respectively, and engine related parts can be held. Therefore, compared with the form which moves one holding member, the quantity which shifts an engine related part with respect to an apparatus main body can be decreased. Further, since the holding member moves linearly, the direction in which the engine-related parts are displaced from the apparatus main body can be limited. Therefore, the engine-related parts can be securely held with a small force.

  According to the third aspect of the present invention, each holding member is attached to the apparatus main body so as to be movable in the substantially horizontal direction by a pair of guide pins arranged in parallel in the apparatus main body in the substantially horizontal direction. The operating mechanism includes a shaft that is juxtaposed with the guide pin at a substantially intermediate position in the horizontal direction of the pair of guide pins, extends from the apparatus main body and is movably inserted into the holding member, and a handle that is rotatably connected to the shaft. And a link rotatably connected to each of the handle and the holding member.

  Therefore, since the holding member moves by the pair of guide pins and the shaft, the holding member can move linearly with respect to the apparatus main body with good stability. Further, since the shaft is positioned between the pair of guide pins, the operation mechanism can move the holding member in a balanced manner. Thus, the engine-related parts can be stably held by the holding member.

  According to the fourth aspect of the present invention, each holding member has a pressing portion that moves in a substantially horizontal direction and pushes the outer peripheral surface of the disk-like engine-related component toward the center of the apparatus main body. The apparatus main body is formed with a suspending section that is suspended by the suspending apparatus. Accordingly, the center of the disk-like engine-related component can be aligned with the center of the apparatus main body by the pressing portions of the pair of holding members. Therefore, when the holding device is suspended by the suspension device, the engine-related parts can be suspended by the suspension device via the holding device in a well-balanced manner.

Teeth that mesh with the cell motor are formed on the outer periphery of the gear portion 10c.

  As shown in FIGS. 1 and 2, the holding device 1 has a device main body 2 and a pair of holding members 3. The apparatus main body 2 includes a plate portion 2a and a standing portion 2b that stands on the upper surface of both end portions of the plate portion 2a. The plate portion 2a has a narrow width in the central region, and a hanging portion 6 is provided on the upper surface of both side positions of the central region. A hole 6 a through which the wire 11 a of the suspending device 11 is inserted is formed in the suspending portion 6, and the holding device 1 can be suspended by the suspending device 11.

  As shown in FIGS. 1 and 3, a positioning member 5 and a reinforcing member 2d are provided on the lower surface of the plate portion 2a. The positioning member 5 has a resin cylindrical tube portion 5a and a screw 5b for attaching the tube portion 5a to the lower surface of the plate portion 2a. The positioning members 5 are provided at the four corners of the plate portion 2a, and are positioned on the engine-related component 10 to position the apparatus main body 2 with respect to the engine-related component 10 in the vertical direction. The reinforcing member 2d extends in the left-right direction substantially at the center in the width direction of the plate portion 2a, and suppresses deformation of the plate portion 2a in the upward convex direction.

  As shown in FIGS. 1 and 2, each holding member 3 is attached to both sides of the apparatus body 2 so as to be linearly movable. The holding member 3 includes a plate portion 3a provided side by side on the side of the apparatus main body 2, a pair of guide pins 3d provided on the upper portion of the plate portion 3a, and a pair of pressing portions 3b provided on the lower portion of the plate portion 3a. is doing. The guide pin 3d has a columnar shape, and extends in a substantially horizontal direction from both sides in the width direction of the plate portion 3a toward the apparatus main body 2. The guide pin 3d is slidably inserted into the hole of the standing part 2b of the apparatus main body 2. At the tip of the guide pin 3d, a retaining portion 3d1 is provided for preventing the guide pin 3d from coming off from the upright portion 2b.

  As shown in FIGS. 1 and 3, the pressing portions 3b are located on both sides of the plate portion 3a in the lower width direction. The pressing portion 3b extends in a substantially horizontal direction from the plate portion 3a toward the apparatus main body 2. The distal end portion of the pressing portion 3b can be inserted into the main body portion 10a through between the flange portion 10b and the gear portion 10c of the engine-related component 10. An abutting surface 3b1 that abuts on the main body 10a is formed at the tip of the pressing portion 3b. The contact surface 3b1 has an arc shape having a curvature corresponding to the outer peripheral surface of the main body 10a of the engine-related component 10, and pushes the engine-related component 10 toward the center of the apparatus main body 2. The contact surface 3b1 is inclined toward the engine-related component 10 and upward. Therefore, the engine-related component 10 is pushed upward toward the positioning member 5 by the contact surface 3b1.

  A buffer portion 3c is attached to the pressing portion 3b as shown in FIGS. The buffer portion 3c is made of resin and is positioned at a corner portion at the lower end of the distal end of the pressing portion 3b. Therefore, the buffer portion 3c can avoid the pressing portion 3b from directly hitting the engine-related component 10, and the engine-related component 10 can be prevented from being damaged by the pressing portion 3b.

  An operation mechanism 4 is provided between the apparatus main body 2 and each holding member 3 to move the holding member 3 relative to the apparatus main body 2 as shown in FIGS. The operation mechanism 4 has a shaft 4a, a handle 4b, and a link 4c. The shaft 4a has a columnar shape, and is inserted through the mounting portion 2c and the standing portion 2b that stand on the upper surface of the plate portion 2a of the apparatus main body 2 and is mounted so as not to slide. The plate portion 3a of the holding member 3 is slidably inserted into the shaft 4a.

  The handle 4b is L-shaped as shown in FIGS. 1 and 2, and one end 4b1 is rotatably attached to the end of the shaft 4a. A resin grip 4b2 is attached to the other end of the handle 4b. One end portions 4c1 of the pair of links 4c are rotatably connected to both side portions of the bent portion of the handle 4b. The other end portion 4c2 of the link 4c is rotatably connected to a convex portion 3a1 protruding at the center of the upper edge of the plate portion 3a.

  Therefore, by rotating the handle 4b with respect to the apparatus main body 2, the link 4c is moved by the handle 4b, and the holding member 3 is moved by the link 4c. The holding member 3 is guided by the shaft 4 a and the guide pin 3 d and linearly moves in a substantially horizontal direction with respect to the apparatus main body 2. The pair of holding members 3 move between a holding position that holds the engine-related component 10 by linearly decreasing the interval and a release position that releases the engine-related component 10 by linearly increasing the interval. To do. A biasing member 7 that biases the holding member 3 to the release position is provided on the outer periphery of the guide pin 3d.

  As shown in FIGS. 1 and 4, a lock mechanism 8 that locks the holding member 3 in the holding position is provided between each operation mechanism 4 and each holding member 3. The lock mechanism 8 has a lock body 8a, an arm 8b, and a lever 8d. The lock body 8a is juxtaposed with the handle 4b, and a pair of arms 8b extend from both sides of the lock body 8a toward the handle 4b. The distal end portion of the arm 8b is rotatably connected to the convex portion 4d of the handle 4b by a connecting pin 8c. A claw 8a1 protruding toward the handle 4b is formed at the lower end of the lock body 8a. On the upper part of the plate portion 3a, a latching portion 3e for latching the claw 8a1 is formed.

  As shown in FIGS. 1 and 4, a biasing member 9 is provided between the upper portion of the lock body 8a and the handle 4b to bias the lock body 8a in a direction in which the claw 8a1 is hooked on the hook 3e. . Therefore, the claw 8a1 is latched to the latching portion 3e by the biasing force of the biasing member 9. As a result, the handle 4 b cannot move to the apparatus main body 2, and the holding member 3 is locked to the lock position with respect to the apparatus main body 2.

  As shown in FIGS. 1 and 4, a lever 8d extending upward is provided on the upper portion of the lock body 8a. By tilting the lever 8d against the urging member 9 toward the handle 4b, the claw 8a1 is detached from the latching portion 3e. Accordingly, the handle 4b can be tilted with respect to the apparatus main body 2, and the holding member 3 can be moved from the holding position of FIG. 1 to the release position of FIG. A restricting member 4e protruding toward the lock body 8a is attached to the handle 4b. Accordingly, the rotation of the lock body 8a urged by the urging member 9 can be restricted by the restricting member 4e in the state shown in FIG.

  As described above, the holding member 3 is attached to the apparatus main body 2 so as to be linearly movable as shown in FIGS. The holding member 3 is linearly moved with respect to the apparatus main body 2 by the operation mechanism 4, whereby the distance between the pair of holding members 3 changes linearly, and the pair of holding members 3 cooperate to hold the engine-related component 10. To do.

  Therefore, the holding member 3 moves linearly with respect to the apparatus body 2 and holds the engine-related component 10 linearly. Therefore, since the holding member 3 does not consider the holding angle with respect to the engine-related component 10, the engine-related component 10 of another size can be held only by changing the moving amount of the holding member 3 or the like. The holding device 1 holds the engine-related component 10 by a linear distance change between the pair of holding members 3. Therefore, engine-related parts and the like that do not have holes can be held. Thus, it is excellent in versatility. Further, since the holding member 3 moves with respect to the apparatus main body 2, the moving part is smaller than the conventional arrangement in which the entire apparatus moves like a scissor type, and the holding apparatus 1 can be miniaturized.

  In addition, the holding device 1 includes a positioning member 5, a pair of holding members 3, and a lock mechanism 8 as shown in FIG. 1. Therefore, the apparatus main body 2 can be positioned on the engine-related component 10 by the positioning member 5. Then, the engine-related component 10 can be held by moving the pair of holding members 3. Therefore, the amount by which the engine-related component 10 is shifted with respect to the apparatus main body 2 can be reduced as compared with a mode in which one holding member is moved. Further, since the holding member 3 moves linearly, the direction in which the engine-related component 10 is displaced with respect to the apparatus main body 2 can also be limited. Therefore, the engine-related component 10 can be securely held with a small force.

  As shown in FIG. 2, each holding member 3 is attached to the apparatus main body 2 so as to be movable in the substantially horizontal direction by a pair of guide pins 3d arranged in parallel in the apparatus main body 2. The operating mechanism 4 has a shaft 4a that is juxtaposed with the guide pin 3d at a substantially intermediate position in the horizontal direction of the pair of guide pins 3d and that extends from the apparatus main body 2 and is movably inserted into the holding member 3. Therefore, since the holding member 3 is moved by the pair of guide pins 3d and the shaft 4a, the holding member 3 can move linearly with respect to the apparatus main body 2 with good stability. Further, since the shaft 4a is positioned between the pair of guide pins 3d, the operation mechanism 4 can move the holding member 3 in a balanced manner. Thus, the engine-related component 10 can be stably held by the holding member 3.

  Each holding member 3 has a pressing portion 3b that faces the outer peripheral surface of the disk-shaped engine-related component 10 and presses the outer peripheral surface toward the center of the apparatus main body 2 as shown in FIGS. The apparatus main body 2 is formed with a hanging portion 6 that is hung by a hanging apparatus 11. Therefore, the center of the disk-like engine-related component 10 can be aligned with the center of the apparatus main body 2 by the pressing portions 3 b of the pair of holding members 3. Therefore, when the holding device 1 is suspended by the suspension device 11, the engine-related component 10 can be suspended by the suspension device 11 via the holding device 1 in a well-balanced manner.
