Description

[Technical Field]

[0001] The present invention relates to an attachment aid. [Background technology]

[0002] For example, when setting a test piece as a gripping object in a tensile testing device, it is known to hold the test piece with a gripping tool and set it in the tensile testing device via the gripping tool (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 2014-503802 Summary of the Invention [Problem to be solved by the invention]

[0004] On the other hand, when attaching the test piece to a test apparatus, it is generally necessary to remove the grip from the test apparatus and then attach the sample to the grip perpendicular to the center position of the grip.

[0005] However, when an operator holds a test piece in his / her hand and directly attaches it to a gripping tool, the accuracy of the attachment largely depends on the operator's sense of touch. In other words, the attachment accuracy of the gripping object varies depending on the operator's skill level and other operational capabilities. For this reason, there is a concern that the reproducibility of tests in which an operator holds a gripping object in his / her hand and directly attaches it to a gripping tool may vary.

[0006] An object of the present invention is to provide an attachment aid that enables an object to be gripped to be attached to a gripping tool with high precision and stability by reducing the degree of dependence on the worker's working ability. [Means for solving the problem]

[0007] (1) The attachment aid of the present invention is an attachment aid that can be used as an auxiliary tool to attach an object to be gripped by a gripping tool, and includes a main body in which the gripping tool and the object to be gripped can be set, and the main body includes a first setting section in which the gripping tool can be removably set and a second setting section in which the object to be gripped can be removably set, and the second setting section includes a sliding surface on which the object to be gripped can slide, and the sliding surface extends toward the first setting section. The attachment aid of the present invention enables the object to be accurately and stably attached to the gripping tool by reducing dependence on the worker's working ability.

[0008] (2) In the attachment aid of (1) above, the first set part has two opposing surfaces for sandwiching and positioning the gripping tool so that the gripping mouth of the gripping tool faces horizontally, and the slide surface extends horizontally so that the object to be gripped can be placed on it. In this case, after placing the object to be gripped on the slide surface, the object to be gripped can be accurately fed into the gripping tool by simply sliding the object to be gripped horizontally toward the first set part.

[0009] (3) In the attachment aid of (2) above, it is preferable that the first setting part has a placement surface on which the gripping tool can be placed, the placement surface being one of two stepped surfaces provided on the main body, and the slide surface being the other of the two stepped surfaces provided on the main body. In this case, the gripping tool and the object to be gripped can be easily set and removed.

[0010] (4) In the mounting aid of (3) above, it is preferable that the mounting surface and the sliding surface each have a height such that the central axis of the gripping tool when placed on the mounting surface coincides with the central axis of the object to be gripped when placed on the sliding surface. In this case, with the gripping tool set in the first setting unit, simply by sliding the object to be gripped set in the second setting unit along the sliding surface, centering can be easily performed so that the central axis of the object to be gripped is aligned with the central axis of the gripping tool.

[0011] (5) In the mounting aid of (3) or (4) above, when the gripping tool is capable of being adjusted using a tool, it is preferable that the mounting surface and the sliding surface each have a height that allows the tool to be easily handled when the gripping adjustment of the gripping tool is performed using the tool. In this case, the gripping adjustment of the gripping tool can be easily performed while the gripping tool is set in the first setting part.

[0012] (6) In the attachment aid of any one of (1) to (5) above, it is preferable that the slide surface has a guide protrusion on the outer edge in the width direction of the slide surface for guiding the object to be gripped to the gripping opening. In this case, the object to be gripped can be easily moved toward the gripper set in the first set part without dropping out of the second set part.

[0013] (7) In the attachment aid of any one of (1) to (6) above, when the gripping tool has a knob at a position opposite to the gripping opening of the gripping tool, the main body further has a knob accommodating recess that can detachably accommodate the knob. In this case, the gripping tool with a knob can be easily set.

[0014] (8) In the attachment aid of any one of (1) to (7) above, it is preferable that the main body further includes a partition that can come into contact with the object to be gripped when the object penetrates the gripping tool. In this case, the object to be gripped can be easily removed from the attachment aid together with the gripping tool. [Effects of the Invention]

[0015] According to the present invention, it is possible to provide an attachment aid that can accurately and stably attach an object to be gripped to a gripping tool by reducing the degree of dependence on the worker's working ability. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] An attachment aid according to one embodiment of the present invention will be described below with reference to the drawings.

[0018] FIG. 1 is a perspective view showing an attachment aid 1 (hereinafter also referred to as "attachment aid 1") according to one embodiment of the present invention, as seen from the front side.

[0019] Here, in this disclosure, "up and down" refers to the position of the assisting tool 1 when it is upright with its bottom as the base point. Also, in this disclosure, "the front of the assisting tool 1" refers to the side of the assisting tool 1 that faces the user when the user performs work using the assisting tool 1. Also, in this disclosure, "horizontal direction" refers to the direction perpendicular to the up and down direction, and refers to the left and right direction when the user performs work with the assisting tool 1 in front. Here, "left and right direction" refers to the position when the assisting tool 1 is viewed from the front. Additionally, in this disclosure, "height" refers to the length in the up and down direction. Also, in this disclosure, "length" simply refers to the length in the horizontal direction. Furthermore, in this disclosure, "depth direction" refers to the direction perpendicular to the up and down direction and the horizontal direction. Additionally, in this disclosure, "width" refers to the length in the depth direction.

[0020] The auxiliary tool 1 according to this embodiment can be used as an auxiliary tool for attaching a test piece (object to be gripped) 20 to the gripping tool 30 by causing the gripping tool 30 to grip the test piece 20 .

[0021] FIG. 7 is a front view schematically illustrating an example of a gripping tool 30 to which a test piece 20 is attached using an auxiliary tool 1. In this disclosure, the "front of the gripping tool 30" refers to the side of the gripping tool 30 where the gripping opening A30, through which the test piece 20 is inserted, is open. Also, in this disclosure, the "rear of the gripping tool 30" refers to the side of the gripping tool 30 opposite the gripping opening A30. FIG. 8 shows the rear side of the gripping tool 30 in a perspective view from the bottom. Also, FIG. 9 shows a plan view of the gripping tool 30.

[0022] As shown in FIG. 7, the test piece 20 is a plate-shaped test piece. In this embodiment, the test piece 20 is a rectangular plate-shaped piece, and the longitudinal direction of the test piece 20 extends in a direction perpendicular to the drawing. In this embodiment, the test piece 20 is a flat test piece as shown in FIG. 7. In this embodiment, the test piece 20 is gripped by a gripping tool 30 so that the short side direction of the test piece 20 is parallel to the up-down direction as shown in FIG. 7. In the present disclosure, the test piece 20 is a rubber plate. The test piece 20 is, for example, a test piece used for a tensile test.

[0023] In this embodiment, the gripping tool 30 is a metal gripping tool. In this embodiment, the gripping tool 30 includes a frame 31, a fixed clamp 32, and a movable clamp 33. In this embodiment, the frame 31 is a rectangular frame as shown in FIG. 7. In this embodiment, the frame 31 includes two vertical frames 31a and two horizontal frames 31b. The fixed clamp 32 and the movable clamp 33 are disposed inside the frame 31. In this embodiment, the fixed clamp 32 is fixed to one of the two vertical frames 31a (hereinafter also referred to as the "one-side vertical frame 31a1"). The movable clamp 33 can be moved between the fixed clamp 32 and the other of the two frames 31a (hereinafter also referred to as the "other-side vertical frame 31a2"). The gripping tool 30 can insert the test specimen 20 in a vertically placed state as shown in Figure 7 through a gripping opening A30 formed between the fixed clamp 32 and the movable clamp 33. The gripping tool 30 can grip the test specimen 20 inserted inside the gripping opening A30 by moving the movable clamp 33 closer to the fixed clamp 32. On the other hand, the gripping tool 30 can remove the test specimen 20 gripped by the fixed clamp 32 and the movable clamp 33 by moving the movable clamp 33 away from the fixed clamp 32. In this embodiment, the gripping tool 30 can be moved along a guide pin 34 provided between the fixed clamp 32 and the other-side vertical frame 31a2 by passing the movable clamp 33 through the guide pin 34. Additionally, in this embodiment, the movable clamp 33 can be advanced and retracted and positioned by an adjustment screw 35 that passes through the other-side vertical frame 31a2. In this embodiment, the advancement and retraction of the adjustment screw 35 can be adjusted using a tool. For example, as shown in FIG. 8, in this embodiment, a hexagonal hole 35a opens at the end 35e of the adjustment screw 35. As a result, in this embodiment, the advancement and retraction amount of the movable clamp 33, i.e., the opening and closing amount of the gripping mouth A30, can be adjusted to an appropriate amount by using a hexagonal wrench with the adjustment screw 35.

[0024] Additionally, as shown in FIG. 8 , in this embodiment, the grip 30 is provided with a tab 36 on the opposite side of the frame 31 from the gripping mouth A 30. In this embodiment, the grip 36 is provided with an attachment portion 36a that is attached to the tensile tester and a connecting portion 36b that connects the attachment portion 36a to the fixed clamp 32. For example, as shown in FIG. 8 , the test specimen 20 can be attached to the grip 30 by gripping one end 21 of the test specimen 20 with the fixed clamp 32 and the movable clamp 33. In FIG. 9 , the state in which one end 21 of the test specimen 20 is attached to the grip 30 is shown by a dashed line. After the test specimen 20 is fixed to the grip 30, the grip 30 can be attached to the tensile tester.

[0025] FIG. 10 schematically illustrates a state in which a grip 30 to which a test specimen 20 is attached is set in a tensile tester. In the present disclosure, the grip 30 preferably grips and attaches the test specimen 20 to the grip 30 so that the central axis O1 of the grip 30 coincides with the central axis O2 of the test specimen 20. Here, the central axis O1 of the grip 30 is a vertical axis passing through the center of gravity of the grip 30 when attached to the tensile tester. Furthermore, the central axis O2 of the test specimen 20 is a vertical axis passing through the center of gravity of the grip 30 when attached to the tensile tester. The grip 30 to which the test specimen 20 is fixed can be attached, for example, to a mounting portion 110 arranged on the upper side. In this example, the other end 22 of the test specimen 20 hanging from the grip 30 is fixed to a gripping portion 120 provided on the tensile tester.

[0026] The auxiliary tool 1 in FIG. 1 includes a main body 2 on which the gripping tool 30 and the test piece 20 can be set. In this embodiment, the auxiliary tool 1 includes the main body 2 and a base 9 that supports the main body 2. In this embodiment, the main body 2 is a rectangular parallelepiped block. The main body 2 includes a front face Ff, a right side face Fr, a left side face Fl, a back face Fb, and a top face Ft. In this embodiment, the auxiliary tool 1 can be used by positioning the front face Ff (back face Fb) of the main body 2 so that it is parallel to the horizontal direction. The material of the main body 2 is not particularly limited as long as it has the strength and hardness to fix the metal gripping tool 30. Examples of such materials include metal and hard plastic (polycarbonate, polyacrylic, etc.).

[0027] The main body 2 includes a first setting section 3 in which the gripping tool 30 can be removably set, and a second setting section 4 in which the test piece 20 can be removably set. In this embodiment, the first setting section 3 and the second setting section 4 are each provided on the front side (the front side of the drawing) of the main body 2, i.e., the front side of the auxiliary tool 1. The first setting section 3 and the second setting section 4 are provided in positions adjacent to each other in the horizontal direction.

[0028] In this embodiment, the first setting section 3 includes a placement surface F1 on which the gripping tool 30 is placed to position it in the vertical direction, two opposing surfaces F2 that laterally sandwich and position the frame 31 of the gripping tool 30, and a depth surface F3 that contacts the frame 31 of the gripping tool 30 to position it in the depth direction. In this embodiment, the first setting section 3 is configured by a first step provided on the main body 2. The first step is provided on the front side of the main body 2. In this embodiment, the first step is a step that opens up the upper front ridge 2e1 of the main body 2. In this embodiment, the placement surface F1 is a step surface of the first step, and the front side of the placement surface F1 in the depth direction opens up to the front surface Ff of the main body 2. In this embodiment, the placement surface F1 is a horizontal plane that becomes horizontal when the auxiliary tool 1 is placed on a horizontal installation surface. In addition, in this embodiment, the depth surface F3 is a wall surface of the first step. The wall surface of the first step, i.e., the depth surface F3, extends upward from the rear edge of the placement surface F1 in the depth direction and is open to the top surface Ft of the main body 2. In this embodiment, the depth surface F3 is a vertical surface that is perpendicular to the horizontal plane when the auxiliary tool 1 is placed on a horizontal placement surface. In addition, in this embodiment, the two opposing surfaces F2 each laterally define the first step provided on the main body 2. In this embodiment, the two opposing surfaces F2 each extend upward from the left and right edges of the placement surface F1. In this embodiment, the opposing surfaces F2 are also vertical surfaces that are perpendicular to the horizontal plane when the auxiliary tool 1 is placed on a horizontal placement surface. That is, in this embodiment, the first setting section 3 is defined by the placement surface F1, the two opposing surfaces F2, and the depth surface F3. Therefore, as shown in FIG. 1, in this embodiment, the first setting section 3 is open on the front surface Ff and the top surface Ft as well as the upper front ridge 2e1 of the main body 2. This allows the gripping tool 30 to be inserted from at least one of the front surface Ff and the top surface Ft into the first setting part 3. That is, in this embodiment, the gripping tool 30 can be accommodated in the first setting part 3 by inserting the gripping tool 30 from at least one of the front side and the top side of the auxiliary tool 1.

[0029] In this embodiment, the second setting section 4 includes a slide surface F5 on which the test piece 20 is placed to position it in the vertical direction, and a wall surface F6 that contacts the side of the test piece 20 to position it in the depth direction. In this embodiment, the second setting section 4 is configured as a second step provided on the main body 2. The second step is adjacent to the first step on the right side of the first step. The second step is also provided on the front side of the main body 2. In this embodiment, the second step is a step in which the upper ridge 2e1 on the front side of the main body 2 and the upper ridge 2e2 on the right side of the main body 2 are open. In this embodiment, the slide surface F5 is the step surface of the second step, and the front side of the slide surface F2 in the depth direction is open to the front surface Ff of the main body 2. In this embodiment, the slide surface F5 is a horizontal plane that is horizontal when the auxiliary tool 1 is placed on a horizontal installation surface. In this embodiment, the wall surface F6 is the wall surface of the second step. The wall surface of the second step, i.e., wall surface F6, extends upward from the rear edge of the slide surface F5 in the depth direction and opens to the top surface Ft of the main body 2. In this embodiment, wall surface F6 is a vertical surface that is perpendicular to the horizontal plane when the auxiliary tool 1 is placed on a horizontal installation surface. In addition, in this embodiment, the left side of the second step is open because it is connected to the first step. Also, in this embodiment, the right side of the second step is open to the right side surface Fr of the main body 2 because it is connected to the right side surface Fr. That is, in this embodiment, the second setting section 4 is defined by the placement surface F5 and wall surface F6, which are open in the left-right direction. Therefore, as shown in FIG. 1 , in this embodiment, the second setting section 4 is open not only to the front upper edge 2e1 and the right upper edge 2e2 of the main body 2, but also to the front surface Ff and top surface Ft, the first setting section 3 side, and the right side surface Fr of the main body 2. This allows the test strip 20 to be placed on at least one of the front face Ff, top face Ft, and right side face Fr in the second setting section 4. That is, in this embodiment, the test strip 20 can be placed on the second setting section 4 from at least one of the front side, top side, and right side of the auxiliary tool 1.

[0030] Additionally, in this embodiment, the slide surface F5 is provided with a guide protrusion 5 on the outer edge in the width direction of the slide surface F5, which guides the test specimen 20 set in the second setting unit 4 to the gripping tool 30. FIG. 2 is a right side view of the auxiliary tool 1. In this embodiment, the guide protrusion 5 stands perpendicular to the slide surface F5. In this embodiment, the inner surface F7 of the guide protrusion 5 can slidably hold the test specimen 20. The height h5 of the guide protrusion 5 is the height from the slide surface F5. The height h5 must be such that the test specimen 20 cannot easily climb over it when inserted between the inner surface F7 of the guide protrusion 5 and the wall surface F6. The height h5 can be, for example, 0.3 mm to 2.0 mm. However, the height h5 can be changed as appropriate depending on the size of the test specimen 20, etc.

[0031] Fig. 3 shows the auxiliary tool 1 in use, taken along the line XX in Fig. 2. Fig. 3 shows a state in which a gripping tool 30 is set in the first setting section 3, and a test piece 20 is set in the second setting section 4. Fig. 4 is another cross-sectional view of the auxiliary tool 1 in use, taken along the line XX in Fig. 2. Fig. 4 shows a state in which the test piece 20 is inserted into the gripping opening A30 of the gripping tool 30 set in the first setting section 3 by moving the test piece 20 along the slide surface F5.

[0032] In this embodiment, the first set unit 3 positions the gripper 30 in the left-right direction by sandwiching the gripper 30 between two opposing surfaces F2 so that the gripping mouth A30 of the gripper 30 faces horizontally. The slide surface F5 extends horizontally so that the test piece 20 can be placed thereon. The horizontal distance between the two opposing surfaces F2 is preferably 0.2 mm to 1.5 mm wider than the length dimension of the gripper 30 in the central axis direction. If the difference between the horizontal distance between the two opposing surfaces F2 and the length dimension of the gripper 30 in the central axis direction is less than 0.2 mm, interference may occur between different grippers 30 due to errors in the length dimension of the gripper 30 in the central axis direction. For this reason, the horizontal distance between the two opposing surfaces F2 is preferably 0.2 mm or more wider than the length dimension of the gripper 30 in the central axis direction. Furthermore, if the gap exceeds 1.5 mm, the gripping tool 30 will not be fixed sufficiently, making it difficult to accurately attach the test piece 20. For this reason, it is preferable that the lateral distance between the two opposing surfaces F2 is 1.5 mm or less compared to the length dimension of the gripping tool 30 in the central axis direction.

[0033] As shown by the arrow in Figure 3, the slide surface F5 allows the test specimen 20 to slide laterally. In this embodiment, the slide surface F5 extends toward the gripping mouth A30 of the gripper 30 set in the first setting unit 3. In this embodiment, the test specimen 20 placed on the slide surface F5 can be moved accurately to the gripping mouth A30 of the gripper 30 set in the first setting unit 3 by moving it along the slide surface F5 and the wall surface F6, as shown in Figure 4.

[0034] Furthermore, as shown in Figure 3, in this embodiment, the mounting surface F1 of the first set section 3 and the slide surface F5 of the second set section 4 each have heights (h1, h2) that align the central axis O1 of the gripping tool 30 when the gripping tool 30 is placed on the mounting surface F1 with the central axis O2 of the test piece 20 when the test piece 20 is placed on the slide surface F5.

[0035] In this embodiment, height h1 is the height from the bottom surface of the base 9 (the installation surface of the auxiliary tool 1) to the placement surface F1. Also, in this embodiment, height h2 is the height from the bottom surface of the base 9 (the installation surface of the auxiliary tool 1) to the slide surface F5. Note that in this embodiment, the bottom surface of the base 9, i.e., the installation surface of the auxiliary tool 1, is a horizontal plane.

[0036] When the gripping tool 30 is adjustable using a tool, as in this embodiment, the height h1 is preferably set so that the tool can be easily manipulated when the gripping tool 30 is adjusted using the tool. The height h2 is also preferably set to match the height h1. That is, in this embodiment, the heights h1 and h2 of the mounting surface F1 and the slide surface F5 are preferably set so that the tool can be easily manipulated when the gripping tool 30 is adjusted using the tool. When the position of the movable clamp 33 of the gripping tool 30 is fixed using a tightening tool such as a wrench or screwdriver, as in this embodiment, a height that is easy for the user to use is required. When using a tool such as the tightening tool, the height h1 is preferably 10 mm or more. The height h2 is preferably 20 mm or more. The height h3 of the center axis of the adjustment screw 35 provided on the gripping tool 30 is preferably 25 mm or more relative to the installation surface.

[0037] Additionally, in this embodiment, as shown in FIG. 4, the main body 2 further includes a partition 6 that can come into contact with the longitudinal end 20e of the test piece 20 when one end 21 of the test piece 20 penetrates the gripping tool 30. In this embodiment, the partition 6 is a curved partition located at the upper end of the left-side facing surface F2 of the two facing surfaces F2. In this embodiment, the partition 6 is a curved partition formed with a radius of curvature r when viewed from the front (rear), as shown in FIG. 4. In this embodiment, the height h6 of the partition 6 (see FIG. 3) is set higher than the height h2 of the slide surface F5. Here, the height h6 is the height from the lower surface of the base 9 (the installation surface of the auxiliary tool 1) to the contact point P6 of the partition 6 with the test piece 20. The height h6 must be high enough to prevent the test piece 20 from easily climbing over it when it penetrates the gripping tool 30. It is desirable that the height h6 be at least 1.0 mm higher than the height h2 of the slide surface F5. However, if height h6 is too high, when the test piece 20 penetrates the gripping tool 30, it will interfere with the test piece 20 that protrudes from the gripping tool 30, making it difficult to remove the gripping tool 30 from the auxiliary tool 1. For this reason, it is desirable that the difference between height h6 and height h2 be 80% or less of the width W4 of the test piece 20 (in this embodiment, the length of the wide side of the test piece 20).

[0038] Fig. 5 shows the auxiliary tool 1 in a perspective view from the rear side. Fig. 6 is a plan view showing the auxiliary tool 1 in use. Fig. 6 shows the auxiliary tool 1 with a test piece 20 inserted into the gripper 30 set in the first setting section 3.

[0039] As shown in Fig. 5, in this embodiment, the main body 2 further includes a knob accommodating recess 7 that can removably accommodate the knob 36 provided on the gripping tool 30. In this embodiment, the knob accommodating recess 7 is a recess that is open to the top surface Ft and the left side surface Fl as well as to the upper ridge line 2e3 on the left side surface of the main body 2. Also, as shown in Fig. 6, in this embodiment, when the gripping tool 30 is set in the first setting unit 3, the connecting portion 36b of the knob 36 is accommodated in the knob accommodating recess 7.

[0040] Next, an example of a method for attaching the test piece 20 to the gripping tool 30 using the auxiliary tool 1 will be described.

[0041] As shown in FIG. 1, the user positions the assisting tool 1 so that the first set part 3 and the second set part 4 of the assisting tool 1 face the user directly.

[0042] Next, with the gripping mouth A30 of the gripping tool 30 in Fig. 7 open, the gripping tool 30 is housed in the first setting unit 3 as shown in Fig. 3, thereby setting the gripping tool 30 in a fixed state. In addition, the test piece 20 is housed in the second setting unit 4, thereby setting the test piece 20 slidably between the guide protrusion 5 and the wall surface F6. Thereafter, the test piece 20 is moved along the slide surface F5 toward the first setting unit 3 using the guide protrusion 5 as a guide.

[0043] The sliding of the test piece 20 stops at a position where the longitudinal end 20e of the test piece 20 contacts the partition portion 6. As a result, one end 21 of the test piece 20 is inserted to an appropriate length into the gripping mouth A30 of the gripping tool 30. Thereafter, the test piece 20 inserted into the gripping tool 30 is fixed to the gripping tool 30 by operating the adjustment screw 35 of the gripping tool 30 using a fastening tool such as a screwdriver.

[0044] Once the test piece 20 has been fixed to the gripping tool 30 , the test piece 20 is removed from the auxiliary tool 1 together with the gripping tool 30 .

[0045] This allows the test piece 20 to be attached perpendicularly to the gripper 30 at the center position of the gripper 30 .

[0046] The auxiliary tool 1 includes a main body 2 in which the gripping tool 30 and the test piece 20 can be set, and the main body 2 includes a first setting section 3 and a second setting section 4. In addition, the second setting section 4 includes a slide surface F5 along which the test piece 20 can slide, and the slide surface F5 extends toward the first setting section 3. With the auxiliary tool 1, the test piece 20 can be easily inserted into the gripping opening A30 of the gripping tool 30 by moving the test piece 20 along the slide surface F5. Therefore, with the auxiliary tool 1, the test piece 20 can be accurately and stably attached to the gripping tool 30 by reducing dependency on the worker's work ability.

[0047] In particular, in this embodiment, the first setting unit 3 has two opposing surfaces F2 for sandwiching and positioning the gripping tool 30 so that the gripping mouth A30 of the gripping tool 30 faces laterally, and the slide surface F5 extends laterally so that the test piece 20 can be placed on it. In this case, after placing the test piece 20 on the slide surface F5, the test piece 20 can be accurately fed into the gripping mouth A30 simply by sliding the test piece 20 laterally toward the first setting unit 3.
