Description

Technical Field

[0001] The utility model relates to the technical field of missile mechanics testing, in particular to a clamping tool and a tool assembly. Background Art

[0002] In mechanical tests on cylindrical structures such as missiles, it is necessary to clamp and fix the missile body and other cylindrical structures or columnar structures by clamping fixtures, and then conduct mechanical environmental tests such as vibration, impact, and acceleration on them.

[0003] In the related art, during use, the clamping tooling for columnar structures either has a small adaptation range for the radial dimensions of the preset object to be clamped, or the operations of installing and removing the preset object are cumbersome and inconvenient to use. Utility Model Content

[0004] In view of this, the utility model provides a clamping tool and a tooling assembly to solve the problems in the related art that the clamping working conditions have a small application range and are inconvenient to operate during use.

[0005] On the one hand, the utility model provides a clamping tool, including a base, a clamping member, a pressure plate member and an adjusting member. The first end of the clamping member is rotatably connected to the base, the second end of the clamping member is detachably connected to the base, a clamping through hole is provided between the clamping member and the base, and the pressure plate member is arranged in the clamping through hole. Along the radial direction of the clamping through hole, the adjusting member contacts the pressure plate member, and is used to adjust the distance between the pressure plate member and the base or the clamping member.

[0006] Beneficial effect: By rotating the connected base and the clamping member, the clamping member can be rotated and switched between the clamping state and the open state compared with the base. When the clamping member is in the clamping state, a clamping through hole is formed between the clamping member and the base, and the clamping member can be kept in a stable clamping state through a detachable connection structure, at which time a preset object of a columnar structure can be clamped in the clamping through hole. Along the radial direction of the clamping through hole, a pressing plate can be arranged between the preset object and the base or the clamping member, and the position of the pressing plate can be adjusted by the adjusting member so that the preset object is squeezed and fixed in the clamping through hole by the pressing plate.

[0007] Since the distance between the pressure plate and the base or the clamping member can be adjusted by the adjusting member, within the maximum range of the clamping through hole, the position of the pressure plate can be adjusted by the adjusting member, so as to adapt to clamping a variety of preset objects of smaller sizes, thereby improving the clamping adaptation range of the clamping tooling for preset objects of different sizes.

[0008] Furthermore, since the first end of the clamping member is rotatably connected to the base, and the second end of the clamping member is detachably connected to the base, when the clamping member is in the clamping state, the detachable clamping member can stably clamp the preset object in the clamping through hole. On this basis, after use, the clamping member can be rotated from the clamping state to the open state by loosening the adjustment member and the detachable structure, so as to remove or put in the preset object. In this process, the clamping member will not be separated from the base, and the operation is simple and convenient.

[0009] In an optional embodiment, the clamping tool further includes a buckle, and the second end of the clamp and one of the base are rotatably connected to the buckle; the buckle has a first position state and a second position state. When the buckle is in the first position state, the second end of the clamp and the base are engaged by the buckle to prevent the second end of the clamp from moving away from the base. When the buckle is in the second position state, the second end of the clamp and the other of the base are disengaged from the buckle.

[0010] Beneficial effect: In the process of operating the buckle and the clamp to replace or install and remove the preset object, the operator can operate the buckle and the clamp with one hand to switch the buckle between the first position state and the second position state, and switch the clamp between the clamping state and the open state. In this process, the clamp and the buckle will not be separated from the base, which is convenient for the user to use and operate.

[0011] In an optional embodiment, the second end of the clamping member is rotatably connected to the buckle member. When the second end of the clamping member approaches and contacts the base, the buckle member is in the first position under the action of gravity.

[0012] Beneficial effect: convenient for users to operate.

[0013] In an optional embodiment, a clamping notch is provided at one end of the base close to the clamping member. When the clamping member is in the first position, the clamping member is at least partially located in the clamping notch and is clamped with the edge of the clamping notch.

[0014] Beneficial effect: By setting a snap-fitting notch on the base to adapt to the snap-fitting structure of the snap-fitting piece, when the snap-fitting piece is in the first position, the snap-fitting piece that is at least partially in the snap-fitting notch can avoid protruding and leaking out, with a simple structure and exquisite appearance.

[0015] In an optional embodiment, the clip includes a connecting portion and a limiting portion. The second end of the clamp and one of the bases are rotatably connected to one end of the connecting portion, and the other end of the connecting portion is connected to the limiting portion. When the clip is in the first position, the second end of the clamp and the other of the bases are in contact and engaged with the limiting portion.

[0016] Beneficial effect: Taking the example of one end of the connection part being rotatably connected to the second end of the clamping member, when the clamping member is in the first position state, the portion of the connection part located between the clamping member and the limiting portion is in the clamping notch. Taking the example of the limiting portion being located below the clamping member in the first position state, the base at at least one side edge below the clamping notch can be in contact with the corresponding limiting portion to prevent the connection part from moving upward and disengaging from the clamping notch, thereby preventing the clamping member from rotating to disengage from the clamping state.

[0017] In an optional embodiment, at least one of the base and the clamping member is provided with an adjustment threaded hole along the radial direction of the clamping through hole. The adjustment member is a bolt, and one end of the bolt away from the head is inserted into the clamping through hole through the adjustment threaded hole and contacts the pressing plate.

[0018] Beneficial effect: By adjusting the setting of the threaded hole, the adjusting member of the bolt structure can be screwed to adjust the gap size between the pressure plate member in the clamping through hole and the base or the clamping member. In this way, within the adaptation range, the position of the pressure plate member can be adjusted by the bolt to stably clamp preset objects of various sizes and specifications, with a simple structure and convenient operation.

[0019] In an optional embodiment, there are multiple pressing plate members, and the multiple pressing plate members are distributed at intervals along the circumference of the clamping through hole, and one pressing plate member is in contact and connected with at least one adjusting member.

[0020] Beneficial effect: Through multiple adjustment parts and multiple pressure plate parts, the position of the pressure plate part can be flexibly adjusted within the circumferential range of the preset object, so that the preset object can be stably clamped in the clamping through hole.

[0021] In an optional embodiment, the pressing plate member is detachably disposed in the clamping through hole.

[0022] Beneficial effect: Taking the contact connection between one end of the adjusting member located in the clamping through hole and the pressing plate as an example, by replacing the pressing plates of different sizes, the side of the pressing plate facing the axis of the clamping through hole can be in contact or fit with the preset object over a large area. While ensuring the clamping stability, it is also beneficial to reduce the local pressure by increasing the contact area, avoiding damage to the surface structure of the preset object.

[0023] In an optional embodiment, the clamping tool further includes a buffer pad, which is located on a side of the pressure plate away from the adjusting member in the clamping through hole, and is made of a conductive material.

[0024] Beneficial effect: By arranging a buffer pad on the side of the pressing plate away from the adjusting member, that is, the buffer pad is between the preset object and the pressing plate, the pressing plate is prevented from directly contacting the preset object to damage the outer wall structure of the preset object. Since the base, the clamping member, the pressing plate and the adjusting member are usually made of metal such as steel or cast iron, the conductive material buffer pad can keep the base and the clamping member and the preset object at zero potential, thereby preventing the electronic components inside the preset object from being damaged by electric shock.

[0025] On the other hand, the utility model further provides a tooling assembly, comprising at least two clamping tools in the above aspect, and the at least two clamping tools are arranged at intervals along the axial direction of the clamping through hole.

[0026] Beneficial effect: By arranging two or more clamping fixtures in the axial direction of the clamping through hole, when the axial dimension of the preset object is long, a larger number of clamping fixtures can be used to stably clamp the preset object, avoiding affecting the vibration, impact, acceleration and other mechanical tests of the preset object such as the projectile.

[0027] In addition, since the tooling assembly also includes the clamping tooling in the above aspect, the tooling assembly has all the beneficial effects of the above-mentioned clamping tooling, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0047] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0048] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0049] Combine the following Figures 1 to 8 , describing the embodiments of the clamping tool and tool assembly of the utility model.

[0050] On the one hand, according to an embodiment of the present utility model, as Figure 1 and Figure 2 As shown, a clamping tool 100 is provided, and the clamping tool 100 includes a base 10, a clamping member 20, a pressure plate member 30, and an adjusting member 40. The first end of the clamping member 20 is rotatably connected to the base 10, and the second end of the clamping member 20 is detachably connected to the base 10, and a clamping through hole 51 is provided between the clamping member 20 and the base 10. The pressure plate member 30 is arranged in the clamping through hole 51. Along the radial direction of the clamping through hole 51, the adjusting member 40 contacts the pressure plate member 30, and is used to adjust the distance between the pressure plate member 30 and the base 10 or the clamping member 20.

[0051] By rotating the connected base 10 and the clamping member 20, the clamping member 20 can be moved relative to the base 10 in the clamping state (such as Figure 3 ) and the open state (as shown Figure 1 When the clamping member 20 is in the clamping state, a clamping through hole 51 is formed between the clamping member 20 and the base 10, and the clamping member 20 can maintain a stable clamping state through a detachable connection structure, and at this time, a preset object of a columnar structure can be clamped in the clamping through hole 51. Along the radial direction of the clamping through hole, a pressing plate 30 can be arranged between the preset object and the base 10 or the clamping member 20, and the position of the pressing plate 30 can be adjusted by the adjusting member 40, so that the preset object is squeezed and fixed in the clamping through hole by the pressing plate 30.

[0052] Since the distance between the pressure plate member 30 and the base 10 or the clamping member 20 can be adjusted by the adjusting member 40, within the maximum range of the clamping through hole 51, the position of the pressure plate member 30 can be adjusted by the adjusting member 40 to adapt to clamping a variety of preset objects of smaller sizes, thereby improving the clamping adaptation range of the clamping tool 100 for preset objects of different sizes.

[0053] Furthermore, since the first end of the clamping member 20 is rotatably connected to the base 10, and the second end of the clamping member 20 is detachably connected to the base 10, when the clamping member 20 is in the clamping state, the detachable connection member can stably clamp the preset object in the clamping through hole 51.

[0054] On this basis, when the use is finished, only the adjusting member 40 and the detachable structure need to be loosened to rotate the clamping member 20 from the clamping state to the open state for removing or putting the preset object in. In this process, the clamping member 20 will not be separated from the base 10, and the operation is simple and convenient.

[0055] It should be noted that the upper side of the base 10 is provided with a groove structure downward, and the lower side of the clamping member 20 is provided with a groove structure upward. When the clamping member 20 is in the clamping state, the two groove structures of the base 10 and the clamping member 20 are aligned to form a clamping through hole 51, which is convenient for accommodating and clamping the preset object.

[0056] In some embodiments, continue to refer to Figure 1 and Figure 2 The clamping tool 100 further includes a buckle 60, and the second end of the clamping member 20 and one of the base 10 are rotatably connected to the buckle 60. The buckle 60 has a first position state and a second position state.

[0057] like Figure 3 As shown, when the buckle 60 is in the first position, the second end of the clamping member 20 and the base 10 are engaged with each other through the buckle 60 to prevent the second end of the clamping member 20 from moving away from the base 10. Figure 4 When the latch 60 is in the second position, the second end of the clamp 20 and the other of the base 10 are out of the latching state with the latch 60 .

[0058] like Figure 3 and Figure 4 As shown, the clamping member 20 is located above the base 10. The second end of the clamping member 20 can be arranged to be rotatably connected to the buckle 60. Figure 3 As shown in the figure, when the clamping member 20 is close to and contacts the base 10 so that the clamping member 20 closes the clamping through hole 51 along the circumferential direction, the buckle member 60 is in the first position state under the action of gravity, so that the clamping member 20 and the base 10 are stably clamped by the buckle member 60. At this time, the position of the pressure plate member 30 can be adjusted by the adjusting member 40 to stably clamp the preset object in the clamping through hole 51.

[0059] If it is necessary to replace or remove the preset object in the clamping through hole 51, the contact relationship between the pressing plate 30 and the preset object is loosened by the adjusting member 40. Figure 4 As shown, a force can be applied to the end of the buckle 60 away from the clamping member 20 to rotate the buckle 60 in a direction away from the base 10 until the buckle 60 leaves the first position and enters the second position. At this time, the buckle 60 and the base 10 are no longer engaged, and then a force can be applied to the clamping member 20 by the buckle 60 to rotate the buckle 60 in a direction away from the base 10. Figure 5 The clamping member 20 shown is composed of Figure 4 Clamping position shown rotates counterclockwise Figure 1 The open state shown. Then the preset object in the clamping through hole 51 can be replaced or removed. If the preset object is not installed in the clamping through hole 51 at this time, the preset object can be placed in the clamping through hole, and then the reverse operation is performed until the preset object is stably clamped.

[0060] In this way, when operating the buckle 60 and the clamp 20 to replace or install or remove the preset object, the operator can operate the buckle 60 and the clamp 20 with one hand to switch the buckle 60 between the first position state and the second position state, and switch the clamp 20 between the clamping state and the open state. In this process, the clamp 20 and the buckle 60 will not be separated from the base 10, which is convenient for the user to use and operate.

[0061] In addition, the latch 60 can also be rotatably connected to one end of the base 10, and the latch 60 can be stably engaged with the clamp 20 in the first position state, and can be disengaged from the clamp 20 in the second position state.

[0062] Alternatively, at the second end of the clamp 20, aligned through holes may be opened on the clamp 20 and the base 10, and then the clamp 20 and the base 10 may be snap-fitted and installed by inserting bolts and nuts into the through holes, which is not limited to this.

[0063] In some embodiments, Figure 5 As shown, the base 10 has a snap-fit ​​notch 11 at one end close to the snap-fit ​​member 60. Figure 3 In the first position shown, the latch 60 is at least partially located in the latch notch 11 and is latched with the edge of the latch notch 11 .

[0064] By setting a snap-fitting notch 11 on the base 10 to adapt to the snap-fitting structure of the snap-fitting member 60, when the snap-fitting member 60 is in the first position, at least part of the snap-fitting member 60 in the snap-fitting notch 11 can avoid protruding out, with a simple structure and a refined appearance.

[0065] In some embodiments, Figure 6 As shown, the buckle 60 includes a connecting portion 61 and a limiting portion 62. The second end of the clamping member 20 and one of the bases 10 are rotatably connected to one end of the connecting portion 61, and the other end of the connecting portion 61 is connected to the limiting portion 62. When the buckle 60 is in the first position, the second end of the clamping member 20 and the other of the bases 10 are in contact and locked with the limiting portion 62.

[0066] like Figure 5 and Figure 6As shown, taking the example of the rotational connection between one end of the connecting portion 61 and the second end of the clamping member 20, when the buckle member 60 is in Figure 3 In the first position state shown in FIG. 1 , the portion of the connecting portion 61 between the locking member 60 and the limiting portion 62 is located in the locking notch 11. Figure 3 Taking the limit portion 62 shown as being located below the clamping member 20 as an example, the base 10 at at least one side edge of the lower side of the clamping notch 11 can be in contact with the corresponding limit portion 62 to prevent the connecting portion 61 from moving upward, thereby preventing Figure 3 The clamping member 20 is shown rotated clockwise to disengage the clamping state.

[0067] It should be noted that, in a natural state without external force, the connecting portion 61 is kept in a vertical state by gravity and is stably located in the engaging notch 11 .

[0068] In which, along the axial direction of the clamping through hole 51, one end of the connecting portion 61 away from the clamping member 20 can be connected to one end of the limiting portion 62, so that the other end of the limiting portion 62 can be clamped and adapted to one side edge of the clamping notch 11. The structure is simple and is conducive to reducing the mass of the clamping member 60.

[0069] Alternatively, along the axial direction of the clamping through hole 51, one end of the connecting portion 61 away from the clamping member 20 can be connected to the middle area of ​​the limiting portion 62, so that the two ends of the limiting portion 62 can be clamped and adapted with the two side edges of the clamping notch 11, thereby improving the stability of the clamping structure.

[0070] In some other embodiments, one end of the connection portion 61 away from the clamping member 20 may also be connected to one end of the limiting portion 62. Along the rotation direction of the connection portion 61, the other end of the limiting portion 62 is located on a side of the connection portion 61 close to the base, so that the limiting portion 62 is located below the base 10 when in the first position, thereby preventing the clamping member 20 from being out of the clamping state.

[0071] It should be noted that in the above solution, a snap-fit ​​notch may be provided at one end of the base 10 close to the snap-fit ​​component 60 , or it may not be provided, and this is not limited.

[0072] In some embodiments, Figures 4 to 6 As shown, along the radial direction of the clamping through hole 51, at least one of the base 10 and the clamping member 20 is provided with an adjustment threaded hole 52. The adjustment member 40 is a bolt, and one end of the bolt away from the head is inserted into the clamping through hole 51 through the adjustment threaded hole 52 and contacts the pressure plate member 30.

[0073] Among them, the head of the bolt refers to the end of the bolt without external threads, and the tail of the bolt refers to the end of the bolt with a screwing part such as an internal hexagonal structure or an external hexagonal structure, which is convenient for screwing the bolt.

[0074] By adjusting the setting of the threaded hole 52, the adjusting member 40 of the bolt structure can be screwed to adjust the gap size between the pressing plate member 30 and the base 10 or the clamping member 20 in the clamping through hole 51. In this way, within the adaptation range, the position of the pressing plate member 30 can be adjusted by the bolt to stably clamp preset objects of various sizes, with a simple structure and convenient operation.

[0075] It should be noted that, in the embodiment of the present application, the end of the adjusting member 40 located in the clamping through hole 51 and the pressing plate member 30 may be in contact connection or in rotational connection.

[0076] If one end of the adjusting member 40 located in the clamping through hole 51 is rotatably connected to the pressing plate 30, that is, a blind hole is provided on the side of the pressing plate away from the axis of the clamping through hole 51, and one end of the adjusting member 40 is rotatably connected to the pressing plate 30 through a stopper located in the blind hole structure, and the blind hole is not a threaded hole structure. That is, during the process of the adjusting member 40 rotating to adjust the position of the pressing plate 30, the adjusting member 40 can rotate relative to the pressing plate 30, and the pressing plate 30 can move along the radial direction of the clamping through hole 51 to clamp the preset object.

[0077] In some embodiments, the pressing plate 30 is detachably disposed in the clamping through hole 51 .

[0078] Taking the contact connection between one end of the adjusting member 40 located in the clamping through hole 51 and the pressing plate member 30 as an example, by replacing the pressing plate members 30 of different sizes, the side of the pressing plate member 30 facing the axis of the clamping through hole 51 can be in contact or fit with the preset object over a large area. While ensuring the clamping stability, it is also helpful to reduce the local pressure by increasing the contact area, avoiding damage to the surface structure of the preset object.

[0079] In some other embodiments, the adjusting member 40 may also be a gas rod structure, which can also adjust the position of the pressing plate 30 to stably clamp the preset object. At this time, one end of the adjusting member 40 located at the clamping through hole 51 can be connected to the pressing plate 30 through a threaded hole.

[0080] For example, if the outer diameter of the preset object is much smaller than the inner diameter of the clamping through hole 51, the pressure plate 30 can be replaced with a smaller inner diameter so that the inner side of the pressure plate 30 and the outer side of the preset object have a larger contact and fitting area.

[0081] In the clamping through hole 51 , the number of the pressing plate members 30 may be one or more.

[0082] like Figure 1 and Figure 2 As shown, a plurality of pressing plate members 30 are disposed in the clamping through hole 51, and the plurality of pressing plate members 30 are distributed at intervals along the circumference of the clamping through hole 51. Correspondingly, one pressing plate member 30 is in contact with and connected to at least one adjusting member 40.

[0083] In this way, through the multiple adjustment members 40 and the multiple pressing plate members 30 , the position of the pressing plate member 30 can be flexibly adjusted within the circumferential range of the preset object, so that the preset object can be stably clamped in the clamping through hole 51 .

[0084] In some embodiments, Figure 2 and Figure 3 As shown, the clamping tool 100 further includes a buffer pad 70 . The buffer pad 70 is located in the clamping through hole 51 on a side of the pressing plate 30 away from the adjusting member 40 , and the buffer pad 70 is made of a conductive material.

[0085] By arranging the buffer pad 70 on the side of the pressing plate 30 away from the adjusting member 40, that is, the buffer pad 70 is between the preset object and the pressing plate 30, the pressing plate 30 is prevented from directly contacting the preset object to damage the outer wall structure of the preset object. Since the base 10, the clamping member 20, the pressing plate 30 and the adjusting member 40 are usually made of metal such as steel or cast iron, the buffer pad 70 made of conductive material can keep the base 10 and the clamping member 20 and the preset object at zero potential, thereby preventing the electronic components inside the preset object from being damaged by electric shock.

[0086] It should be noted that, for example, the side of the pressing plate 30 close to the axis of the clamping through hole is the inner side, and the side of the pressing plate 30 away from the clamping through hole is the outer side. The outer side of each pressing plate 30 is in contact with one or more adjusting members 40. The inner side of each pressing plate 30 is used to clamp a preset object, and the buffer pad 70 is located on the inner side of the pressing plate 30 and between the pressing plate 30 and the preset object.

[0087] During use, take the preset object as a missile body as an example.

[0088] You can Figure 3 The latch member 60 shown in the first position is rotated to Figure 4 The second position state shown in the figure is then continued by applying force to the buckle 60 so that Figure 1 and Figure 4 The clamping member 20 shown in FIG. 1 is rotated counterclockwise until the upper portion of the base 10 is completely opened.

[0089] Then, the clamping through hole 51 (such as Figure 1 Two pressing plates 30 in contact with the base 10 are installed at the positions shown in the figure, and then the elastic body is placed above the two pressing plates 30 (a buffer pad 70 may also be provided between the pressing plates 30 and the elastic body), and a pressing plate 30 is placed at a corresponding position above the elastic body, and then a reverse force is applied to the clamping member 20 to rotate the clamping member 20 clockwise to Figure 7 The position shown in the figure makes the latch 60 be in the first position.

[0090] Finally, by twisting and adjusting the multiple adjusting members 40, the three pressing plates 30 in the clamping through hole 51 can be used to stably squeeze and clamp the elastic body, and the axis of the elastic body is approximately coincident with the axis of the clamping through hole 51. Then, the stably clamped elastic body can be tested for mechanical environmental tests such as vibration, impact, and acceleration. Subsequently, the reverse operation can be performed to disassemble or replace the elastic body after the test.

[0091] The structure is simple and easy to operate. It can meet the requirements of quick disassembly and installation and has high practicality. It can also adapt to clamp projectiles of different diameters, such as projectiles from 40mm to 100mm, which can be flexibly matched.

[0092] On the other hand, the embodiment of the utility model also provides a tooling assembly, such as Figure 8 As shown, the tool assembly includes at least two clamping tools 100 in the above aspect, and at least two clamping tools 100 are arranged along the clamping through hole 51 (such as Figure 1 axial spacing arrangement).

[0093] By arranging two or more clamping tools 100 in the axial direction of the clamping through hole 51, when the axial dimension of the preset object is longer, the preset object can be stably clamped by a larger number of clamping tools to avoid affecting the mechanical testing such as vibration, impact, acceleration, etc. of the preset object such as the projectile.
