Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the conventional fastening device 33, when fastening the base 31 (first member) and the plate 32 (second member) using two fastening devices 33, it was necessary to minimize variations in the distance between the cases 34, 34 and the distance between the clampers 35, 35. For this reason, when machining the two mounting holes 31a, 31a for attaching the cases 34, 34 and the two mounting holes 32a, 32a for attaching the clampers 35, 35 in the base 31 and plate 32, it was necessary to tighten the tolerance of the pitch of the two mounting holes 31a, 31a (32a, 32a).

[0005] This invention was made to solve the above-mentioned conventional problems, and its objective is to provide a fastening engagement receiver and fastening device that do not require a very strict tolerance for the pitch between the first member and the second member when fastening them at two locations.

The mounting body comprises a mounting body main body and a guide member extending in the sliding direction, which serves as a guide means for guiding the cylindrical body in a sliding direction perpendicular to the axis of its receiving hole. In this way, since the cylindrical body is movable in the sliding direction, when fastening the first member and the second member at two points, this engagement receiver can be used on one of the points, and the sliding direction of the cylindrical body can be made along a straight line connecting the two fastening points, thereby eliminating the need for such strict tolerances in the pitch of the two points on each of the first and second members.

[0008] Furthermore, the fastening engagement receiver according to claim 2 is the engagement receiver according to claim 1, wherein the mounting body has a first opposing surface facing the side opposite to the side with the second member. The cylindrical body has a second opposing surface facing the side with the second member so as to face the first opposing surface. Thus, the first opposing surface and the second opposing surface are provided so as to be able to abut each other, and the first opposing surface constitutes a part of the guide means.

[0009] Furthermore, the fastening engagement receiver according to claim 3 is the engagement receiver according to claim 1, wherein the through hole is an elongated hole that is longitudinal in the sliding direction, and the longitudinal inner circumferential surface on the side of the through hole perpendicular to the sliding direction and the outer circumferential surface of the cylindrical body are provided to be able to come into contact with each other, and the longitudinal inner circumferential surface constitutes part of the guide means.

[0010] Furthermore, the fastening engagement receiver according to claim 4 is the engagement receiver according to claim 1, wherein the cylindrical body is formed in a cylindrical shape, and the guided groove is provided so as to go around the cylindrical body in its circumferential direction.

[0011] Furthermore, the fastening engagement receiver according to claim 5 is the engagement receiver according to any one of claims 1 to 4, wherein the guide member consists of a pin-shaped member extending in the sliding direction.

[0012] Furthermore, the fastening engagement receiver according to claim 6 is the engagement receiver according to any one of claims 1 to 4, wherein the guide member consists of a plurality of divided pieces arranged in the sliding direction.

[0013] Furthermore, the fastening device described in claim 7 comprises a fastening engagement receiver described in any one of claims 1 to 4 and the fastening device. [Effects of the Invention]

[0014] According to the fastening engagement receiver and fastening device of this invention, the engagement receiver has a cylindrical body into which the fastening shaft is inserted that is movable in the sliding direction, and when fastening a first member and a second member at two locations, it is not necessary to make the tolerance of the pitch at those two locations on each of the first member and the second member so strict.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, embodiments for carrying out this invention will be described based on the drawings.

[0017] Figures 1 to 15 show one embodiment of the present invention. In the figures, reference numeral 1 indicates a first member, and reference numeral 2 indicates a second member. Reference numeral 3 indicates an engaging receiver, which is positioned on the first member 1 to fasten (more specifically, detachably fasten) the first member 1 and the second member 2 to each other. Reference numeral 10 indicates a fastener positioned on the second member 2, and this fastener 10 and the engaging receiver 3 are suitably used as components of a fastening device that can detachably attach attachments or other second member 2 to the first member 1 located on the side of a manufacturing device or conveying device, for example, in a factory.

[0018] The engagement receiver 3 comprises a mounting body 4 attached to the first member 1 and a cylindrical body 5 supported by the mounting body 4. The inside of the cylindrical body 5 is a receiving hole 5a into which the fastening shaft portion 11 of the fastener 10 is inserted. This receiving hole 5a has an engaging portion 5b that engages with an engaged portion 11a provided on the fastening shaft portion 11 to prevent the fastening shaft portion 11 from coming loose. The mounting body 4 comprises a mounting body body 4a fixed to the first member 1 and having a through hole 4b through which the cylindrical body 5 passes, and a guide means 4c that guides the cylindrical body 5 in a sliding direction 5d perpendicular to the axis 5c of the receiving hole 5a. This guide means 4c comprises a guide member 4d, which is held by the mounting body body 4a, extends in the sliding direction 5d, protrudes into the through hole 4b, and engages with a guided groove 5e provided on the outer circumferential surface of the cylindrical body 5.

[0019] Furthermore, the through-hole 4b of the mounting body 4a is an elongated hole whose length is in the sliding direction 5d. The longitudinal inner circumferential surface 4e of the through-hole 4b, which is perpendicular to the sliding direction 5d, and the outer circumferential surface of the cylindrical body 5 are provided to be able to come into contact with each other, and the longitudinal inner circumferential surface 4e constitutes a part of the guide means 4c.

[0020] Furthermore, the mounting body 4a has a first opposing surface 4f that faces away from the side with the second member 2 (more specifically, it faces away from the side with the second member 2 and is perpendicular to the axis 5c of the receiving hole 5a). On the other hand, the cylindrical body 5 has a second opposing surface 5f that faces away from the first opposing surface 4f and faces away from the side with the second member 2 (more specifically, it faces away from the side with the second member 2 and is perpendicular to the axis 5c of the receiving hole 5a). Thus, the first opposing surface 4f and the second opposing surface 5f are provided so that they can come into contact with each other, and the first opposing surface 4f constitutes a part of the guide means 4c.

[0021] Specifically, the first member 1 and the second member 2 are formed, for example, in the shape of plates, and are arranged so that their plate surfaces face each other. In the illustrated embodiment, the first member 1 and the second member 2 are arranged vertically, with the first member 1 on the lower side and the second member 2 on the upper side. The first member 1 has a mounting hole 1a for attaching the engagement receiver 3. This mounting hole 1a is a stepped hole that penetrates upward (vertically in the illustrated embodiment), and is composed of an upper large-diameter hole 1b and a lower small-diameter hole 1c. The second member 2 has a mounting hole 2a that penetrates vertically for attaching the fastener 10.

[0022] In the engagement receiver 3, the mounting body 4a constituting the mounting body 4 is formed in a disc shape, and the through hole 4b is made so as to penetrate in the vertical direction, which is the thickness direction of the disc-shaped mounting body 4a, and is also the direction of the axis 5c of the receiving hole 5a. The lower surface of this mounting body 4a becomes the first opposing surface 4f.

[0023] Furthermore, the mounting body 4a has an insertion hole 4g ​​into which the guide member 4d is inserted. This insertion hole 4g ​​is made from the outer circumferential surface of the mounting body 4a along the sliding direction 5d, with a portion overlapping the through hole 4b. In other words, a portion of the inner circumferential surface of the insertion hole 4g ​​opens into the through hole 4b. The guide member 4d inserted into the insertion hole 4g ​​protrudes into the through hole 4b through its opening 4h (see Figure 2). Thus, the guide member 4d functions as a guide means 4c for guiding the cylindrical body 5, and also functions as a retaining member to prevent the cylindrical body 5 from coming out of the through hole 4b. The guide member 4d is then retained by a spring pin 4i which acts as a fastener. In addition, a pair of these insertion holes 4g and guide members 4d are provided, and these pair of insertion holes 4g, 4g and guide members 4d, 4d are positioned opposite each other across the through hole 4b. Furthermore, in the illustrated embodiment, the guide member 4d consists of a pin-shaped member 4j extending in the sliding direction 5d.

[0024] The cylindrical body 5 is formed in a cylindrical shape. The aforementioned guided groove 5e is provided on the upper end portion of the outer circumferential surface of the cylindrical body 5. More specifically, the guided groove 5e is provided so as to encircle the cylindrical body 5 once. The portion of the cylindrical body 5 with the guided groove 5e is inserted into the through hole 4b of the mounting body 4a. Furthermore, the portion of the cylindrical body 5 with the guided groove 5e is formed to have a smaller diameter, and the step portion where it transitions from a large diameter to a small diameter is the aforementioned second opposing surface 5f.

[0025] As shown in Figures 4 and 6(b), the receiving hole 5a in the cylindrical body 5 has a first hole 5g with a smaller diameter at the opening where the fastening shaft portion 11 of the fastener 10 is inserted, and a second hole 5h with a larger diameter at the back where the fastening shaft portion 11 is inserted. Between the first hole 5g and the second hole 5h is a tapered surface 5i, which has a larger diameter towards the back (in other words, a smaller diameter towards the second member 2), and this tapered surface 5i becomes the engagement portion 5b. Furthermore, the opening portion of the receiving hole 5a is sufficiently chamfered, and if the tip of the fastening shaft portion 11 hits the chamfered portion 5j due to variations within the pitch tolerance described later, the fastening shaft portion 11 can push the chamfered portion 5j, moving the cylindrical body 5 in the sliding direction 5d and inserting the fastening shaft portion 11 into the receiving hole 5a.

[0026] To attach the engagement receiver 3 to the first member 1, the engagement receiver 3 is inserted into the mounting hole 1a of the first member 1. Specifically, the mounting body 4 of the engagement receiver 3 is inserted into the large diameter hole 1b of the mounting hole 1a, and the cylindrical body 5 of the engagement receiver 3 is inserted into the small diameter hole 1c of the mounting hole 1a. Then, the mounting body 4 (specifically, the mounting body 4a) is attached to the first member 1 using a bolt 21 as a fastener, thereby attaching the engagement receiver 3 to the first member 1.

[0027] The fastener 10 comprises a body 12, a shaft 13, a knob 14, a pin 15, an elastic member 16, and a steel ball 11c. The body 12 is attached and fixed to the second member 2 by a bolt 22 acting as a fastener. The body 12 is hollow and has the aforementioned fastening shaft portion 11 on its lower side. The fastening shaft portion 11 is hollow and has a lateral hole 11b in its peripheral wall. The steel ball 11c is inserted into the lateral hole 11b, and the steel ball 11c becomes the aforementioned engaged portion 11a. The shaft 13 is inside the body 12 and is biased downward by the elastic member 16. The shaft 13 has a hole 13a that passes through it laterally, and the pin 15 is inserted into the hole 13a. The pin 15 has both ends protruding from the hole 13a, and the protruding portions rest on the guide portion 12a formed on the upper end of the main body 12. A knob 14 is attached to the upper end of the shaft 13 by a screw 17, and the shaft 13 and knob 14 are integrated together.

[0028] Therefore, when the fastening shaft portion 11 of the fastener 10 is inserted into the receiving hole 5a of the engagement receiver 3 and the knob 14 is rotated together with the shaft 13, the pin 15 is guided by the guide portion 12a of the main body 12, and the shaft 13 descends together with the knob 14. As a result of this descent, the inclined working surface 13b provided on the circumferential surface of the shaft 13 pushes the steel ball 11c outward, and the steel ball 11c presses against the tapered surface 5i of the receiving hole 5a. In this way, the tapered surface 5i (engaging portion 5b) and the steel ball 11c (engaged portion 11a) engage, fastening the engagement receiver 3 and the fastener 10, and consequently the first member 1 and the second member 2 to each other. Conversely, to release the fastening between the first member 1 and the second member 2, the knob 14 is rotated in the opposite direction together with the shaft 13. This rotation guides the pin 15 to the guide portion 12a of the main body 12, causing the shaft 13 to rise together with the knob 14. This upward movement causes the steel ball 11c to descend the inclined working surface 13b of the shaft 13, disengaging the steel ball 11c (engaged portion 11a) from the tapered surface 5i (engaged portion 5b) of the receiving hole 5a, allowing the fastening shaft portion 11 to be removed from the receiving hole 5a, and consequently, the first member 1 and the second member 2 to be separated from each other.

[0029] Next, the operation and effects of the engagement receiver 3 having the above configuration and the fastening device equipped with the engagement receiver 3 will be explained. The engagement receiver 3 is arranged on the first member 1. This engagement receiver 3 comprises a mounting body 4 attached to the first member 1 and a cylindrical body 5 into which the fastening shaft portion 11 of the fastener 10 arranged on the second member 2 is inserted. The mounting body 4 comprises a mounting body main body 4a and a guide member 4d extending in the sliding direction 5d as a guide means 4c for guiding the cylindrical body 5 in a sliding direction 5d perpendicular to the axis 5c of its receiving hole 5a. In this way, the cylindrical body 5 having the receiving hole 5a is movable in the sliding direction 5d, so when fastening the first member 1 and the second member 2 at two places, by using this engagement receiver 3 on one of them and making the sliding direction 5d of the cylindrical body 5 on the straight line connecting the two fastening points, it is not necessary to make the pitch tolerance at the two points on each of the first member 1 and the second member 2 so strict.

[0030] Figures 10 to 15 show the case where the first member 1 and the second member 2 are fastened at two locations. The engagement receiver 3 is used at one of the two locations, and another engagement receiver 3x is used at the other location. The other engagement receiver 3x has a flange portion 5x integrated with a cylindrical body 5 instead of a mounting body 4, and the cylindrical body 5 is directly attached and fixed to the mounting hole 1x of the first member 1. And, similar to the engagement receiver 3, the inside of the cylindrical body 5 is a receiving hole 5a, and a tapered surface 5i (engaging portion 5b) is provided in the receiving hole 5a. The same fastener 10 is used at both locations. Here, Figures 10 and 11 show the state in which the first member 1 and the second member 2 are separated vertically and before the fastening shaft portion 11 is inserted into the receiving hole 5a; Figures 12 and 13 show the state in which the first member 1 and the second member 2 are superimposed and the fastening shaft portion 11 is inserted into the receiving hole 5a; and Figures 14 and 15 show the state in which the first member 1 and the second member 2 are fastened together by rotating the knob 14. The two pitches mentioned above are, in practice, the pitch of the two mounting holes 1a, 1x in the first member 1 and the pitch of the two mounting holes 2a, 2a in the second member 2.

[0031] It should be noted that the present invention is not limited to the embodiments described above, and various other modifications are possible. For example, although the longitudinal inner circumferential surface 4e of the through hole 4b of the mounting body 4a and the outer circumferential surface of the cylindrical body 5 are capable of contacting each other, they do not necessarily have to be capable of contact. In other words, the longitudinal inner circumferential surface 4e does not have to constitute part of the guide means 4c.

[0032] Furthermore, although the first opposing surface 4f of the mounting body 4a and the second opposing surface 5f of the cylindrical body 5 are capable of contacting each other, they do not necessarily have to be able to contact each other, and the second opposing surface 5f is also optional. In other words, the first opposing surface 4f does not have to constitute part of the guide means 4c.

[0033] Furthermore, the pin-shaped member 4j, which is the guide member 4d, may be solid or hollow, and its cross-sectional shape is not limited to circular; it may also be rectangular or other shapes.

[0034] Furthermore, the guide member 4d does not have to be a pin-shaped member 4j, but may consist of multiple segmented pieces 4k, such as spherical members, arranged in the sliding direction 5d, as shown in Figure 16.

[0035] Furthermore, the guided groove 5e of the cylindrical body 5 is provided so as to go around the cylindrical body 5 in the circumferential direction, but it may also be provided only in part without going around the entire circumference.

[0036] Furthermore, the engaged portion 11a consists of a steel ball 11c provided on the fastening shaft portion 11 of the fastener 10, and the engaged portion 5b consists of a tapered surface 5i provided in the receiving hole 5a of the cylindrical body 5 of the engaging receiver 3. However, as shown in Figures 17 to 19, the engaged portion 11a may consist of a laterally oriented pin material 11d provided on the fastening shaft portion 11, and the engaged portion 5b may consist of a recess 5m formed on the back side of the upper wall 5k provided in the receiving hole 5a. More specifically, the fastener 10 has a shaft 13 inside the main body 12, and the lower end of the shaft 13 protrudes from the main body 12 to form the fastening shaft portion 11. The shaft 13 is rotatable together with the knob 14 and is biased upward by an elastic member 16. The engaging receiver 3 has an upper wall 5k in the receiving hole 5a of the cylindrical body 5. These upper walls 5k are provided in pairs, facing each other with a gap between them. The fastening shaft 11, along with the pin 11d, is inserted into the receiving hole 5a through the opening 5n between these upper walls 5k, 5k. When the knob 14 is rotated together with the shaft 13, the pin 11d presses against the recess 5m of the upper wall 5k from the back side toward the second member 2. In this way, the recess 5m (engaging portion 5b) and the pin 11d (engaged portion 11a) engage, and the first member 1 and the second member 2 are fastened together. Conversely, to release the fastening between the first member 1 and the second member 2, the knob 14 is rotated in the opposite direction together with the shaft 13. In the engagement receiver 3 shown here, the cylindrical body 5 is also movable in the sliding direction 5d.

[0037] Furthermore, as shown in Figures 20 to 22, the engaged portion 11a may consist of a horizontal groove 11e provided on the circumferential surface of the fastening shaft portion 11, and the engaging portion 5b may consist of a steel ball 5p provided on the cylindrical body 5. More specifically, the fastener 10 has a shaft 13 inside the main body 12, and the lower end of the shaft 13 protrudes from the main body 12 to form the fastening shaft portion 11. A vertical groove 11f is formed on this fastening shaft portion 11 from the lower end, and the horizontal groove 11e is formed following the vertical groove 11f. The shaft 13 is rotatable together with the knob 14 and is biased upward by an elastic member 16. In the engaging receiver 3, the receiving hole 5a of the cylindrical body 5 has a steel ball 5p that protrudes into the receiving hole 5a. When the fastening shaft portion 11 is inserted into the receiving hole 5a, the steel ball 5p enters the vertical groove 11f of the fastening shaft portion 11. When the knob 14 is rotated together with the shaft 13, the steel ball 5p moves within the lateral groove 11e of the fastening shaft portion 11. In this way, the steel ball 5p (engaging portion 5b) and the lateral groove 11e (engaged portion 11a) engage, fastening the first member 1 and the second member 2 together. Conversely, to release the fastening between the first member 1 and the second member 2, the knob 14 is rotated together with the shaft 13 in the opposite direction. Incidentally, in this engagement receiver 3, in addition to the steel ball 5p, a ring member 5q and a retaining ring 5r are provided on the cylindrical body 5. Here, the ring member 5q is fitted to the outside of the cylindrical body 5 to prevent the steel ball 5p from coming out. The retaining ring 5r is fitted into the annular groove 5s of the cylindrical body 5 to prevent the ring member 5q from coming out. And in the engagement receiver 3 shown here, the cylindrical body 5 is movable in the sliding direction 5d. [Explanation of Symbols]
