Description

Technical Field

[0001] The utility model belongs to the technical field of cable / tube drag chain clamps, and in particular relates to a staggered overlapping locking clamp for cable / tube drag chains. Background Art

[0002] In modern industrial production, especially in the fields of semiconductor chip manufacturing, micro-electromechanical systems, new nanomaterials, and biomolecular research, the core motion platform mechanism of its precision equipment has very high requirements for motion drag chains. First of all, the influence of mechanical disturbance of the wire must be minimized and the vibration influence of traditional tank chains must be avoided. Secondly, the overall bending radius of the drag chain (i.e., the height of the drag chain) must be minimized. Third, the effective wire density within the unit cross-section of the drag chain must be increased, and more than 300 pin functions must be completed in a very small space. Fourth, the running track, installation space, and wire length of the drag chain are usually accurate to the millimeter level, which is very difficult for this kind of flexible and high-speed moving wire. Fifth, the entire drag chain system cannot generate dust due to movement, and generally needs to reach the CLASS-1 level.

[0003] Nowadays, a new type of soft flat cable / tube is increasingly used as a drag chain in the core motion platform mechanism of precision equipment, replacing the traditional articulated tank chain. However, how to effectively fix this soft flat cable / tube and meet the design requirements to realize a complete and stable new drag chain function has become an urgent problem to be solved.

[0004] At present, the industry mostly installs flexible cables and pipes directly into traditional articulated tank chains. There are no standard dedicated flexible cable fixers and drag chain fixing devices. Some users also try to use simple aluminum plate clamps (or plastic clamps) to fix the wires, such as: mainly using "metal plates + iterative bolts" to fix, and also using "multiple metal plate combinations + bolts and nuts". Although these methods can also achieve cable fixation, they cannot accurately adjust the tightness of the wires and reasonably fix them in layers, and the number of wires that can be fixed per unit cross-sectional area is limited. The overall volume is bloated, and it is impossible to effectively restrain the working area of ​​the new drag chain from warping up and holding up the drag chain. When running at high speed, the wires are prone to shaking and flying, and cannot be quickly assembled and replaced. It is not compatible with the fixation of cable connectors and cannot be modularized and promoted on a large scale. Bolts and nuts are easy to fall and lose, or fall into the precision parts of the equipment during production and maintenance, causing safety accidents.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0051] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0052] Terminology explanation:

[0053] Nanoscale equipment: refers to the equipment's repeatability R and positioning accuracy A of the moving axis, which are in the order of 100 nanometers, 10 nanometers, 1 nanometer, etc. according to ISO-230 and ISO230-6 standards. They are mainly the motion mechanisms of precision core equipment for semiconductor chip manufacturing, micro-electromechanical systems, new nanomaterials, and biomolecular research.

[0054] Tank chain: It is named after its tank-like chain. The unit link of the tank chain is composed of left and right chain plates and upper and lower cover plates. Each section of the drag chain can be opened, which is convenient for assembly and disassembly. There is no need to thread the wires. After opening the cover plate, cables, oil pipes, air pipes, water pipes, etc. can be placed in the drag chain.

[0055] New soft flat cable / tube drag chain: a new type of drag chain without left and right chain plates and upper and lower covers. It directly arranges multiple cables, air pipes, water pipes, etc. in parallel with the smallest electrical unit. The upper and lower surfaces are made of special dust-free and wear-resistant materials through hot pressing or injection molding. It is a new type of drag chain that can fix the two ends of one or more layers of soft flat cables to realize the transmission of current, signals, gas and liquid, and reciprocate according to the designed trajectory.

[0056] New cable / tube drag chain clamp: refers to the device used to fix the two ends of the new soft cable / tube during the manufacturing process of mechanical equipment, so that it can be in the correct theoretical design position to accept the drive of the power components and run according to the motion design route to realize the clamping and fixing device of the drag chain function.

[0057] Bolt: A type of fastener consisting of two parts: the nut head and the screw rod.

[0058] Iteration bolt: The nut head has an internal thread that can match the external thread of the screw. Two or more iterative bolts are connected in series to continuously fix multiple parts. A type of fastener.

[0059] Four-corner fixing: A method of reliably fixing the four corners of the fixed part using fasteners (generally bolts and other fasteners).

[0060] Staggered iterative tightening: refers to the use of multiple fasteners, based on the finite element analysis results of the material structure, to iteratively tighten multiple parts according to a certain rule. When the fasteners are reasonably staggered (usually bolts), the staggered tightening function can be achieved.

[0061] Integrated pressure plate / support plate (support plate): refers to a plate-like part that covers and supports the drag chain (it can have side fixed edges and the long one can contain reinforcing ribs). Its fixed structure is compatible with the pressure block fixture and can be installed interchangeably as a whole.

[0062] As mentioned in the background technology, nowadays, a new type of soft flat cable / tube is increasingly used as a drag chain in the core motion platform mechanism of precision equipment, replacing the traditional articulated tank chain. However, how to effectively fix this soft flat cable / tube and meet the design requirements to realize a complete and stable new type of drag chain function has become an urgent problem to be solved.

[0063] At present, the industry mostly installs flexible flat cables and tubes directly into traditional articulated tank chains. There are no standard dedicated flexible flat cable fixers and drag chain fixing devices. Some users also try to use simple aluminum plate clamps (or plastic clamps) to fix the wires, such as: mainly using "metal plate + iterative bolts" to fix, and also using "multiple metal plates + bolts and nuts". However, the above fixing methods have the following problems:

[0064] First, the bolt + plastic part (aluminum plate) method: Use bolts to directly fix the traditional tank chain end fixing plate. This method of using a traditional articulated tank chain with a soft flat cable inside loses the original design intention of the soft flat cable tube, and the plastic parts are not strong enough, bulky, with a large bending radius, and cannot ensure the running track of the soft flat cable. The weight of the tank chain and the internal cable holder will put a heavy burden on the plastic parts at the end of the tank chain. Due to the unit strength and easy aging and deformation characteristics of the plastic parts, it is difficult to accurately control the running track of the tank chain with a simple bolt fastening method, and it is also prone to breakage, deformation and loosening during frequent and repeated operation.

[0065] Secondly, "metal plate + iterative bolt" and "combination of multiple metal plates + bolts and nuts": This design is derived from the existing wire fixer, and its design is relatively extensive, with a low effective wire density per unit cross-sectional area, and does not consider the mechanical disturbance effect of the drag chain movement on the precision mechanism. The locking force per unit diameter of the iterative bolt is small, it is easy to slip, and it is difficult to disassemble. Because the iterative bolt needs to connect the threads in series and press the metal plate with the flange surface, the thickness of the metal plate needs to be large, so the height and volume of the drag chain cannot be controlled. Although the latter has no iterative structure and reduces the thickness of the overall clamping device, it cannot be locked layer by layer, and cannot effectively control the length of the new drag chain wire, the gap between layers, and the tightness of the overall structure. Moreover, when installing in the clean room, nuts and gaskets are easy to lose and fall, and the magnetic motion mechanism inside the mechanism is easy to absorb these small parts, which is prone to damage to key components and safety accidents. Pneumatic locking tools cannot be used for rapid construction.

[0066] Based on this, the present application provides a staggered locking clamp for cable and tube drag chains according to the requirements of motion mechanics and electrical transmission. Through the scientific staggered locking design of the first clamp and the second clamp, the soft cables and tubes can be reasonably layered and fixed during the assembly process, and the cable tightness can be reasonably adjusted, effectively reducing the bending and warping force of the drag chain and improving the smoothness of the running resistance.

[0067] A staggered overlapping locking clamp for a cable and tube drag chain in one embodiment of the utility model comprises a first clamping member, a second clamping member, and a fastener.

[0068] The first clamping part has a plate-shaped first main body and first locking parts located at opposite ends of the first main body. The first locking part is provided with a row of through holes penetrating in the thickness direction. The through hole row includes first positioning holes located at the head end and the tail end and at least one first through hole and at least one second through hole located between the two first positioning holes.

[0069] The second clamping member has a plate-shaped second main body portion and second locking portions arranged at opposite ends of the second main body portion, and a through hole row penetrating in the thickness direction is arranged on the second locking portion, and the through hole row includes second positioning holes located at the head end and the tail end and at least one first through hole and at least one second through hole located between the two second positioning holes, and the positions of the second positioning holes, the first through holes and the second through holes on the second clamping member are set as follows:

[0070] When the first clamping part and the second clamping part are stacked, the second positioning hole on the second clamping part is arranged correspondingly to the first positioning hole on the first clamping part, the first through hole on the second clamping part is arranged correspondingly to the second through hole on the first clamping part, and the second through hole on the second clamping part is arranged correspondingly to the first through hole on the first clamping part.

[0071] The fastener can be accommodated and locked in the first positioning hole and / or the second positioning hole and / or the first through hole and / or the second through hole to lock and limit the stacked first clamping member and the second clamping member, and the fastener has a head to which force can be applied.

[0072] Wherein, the first through hole is configured such that when the fastener is locked on the first clamp and / or the second clamp, the head of the fastener is completely located in the first through hole or the head surface of the fastener is flush with the surface of the first clamp and / or the second clamp.

[0073] It is understandable that the staggered overlapping locking clamp for cable and tube drag chains of the present application may have multiple first clamps, second clamps, and fasteners. Multiple first clamps and multiple second clamps are alternately stacked, and multiple fasteners are inserted from multiple first through holes and threadedly locked in the second through holes corresponding to the first through holes, thereby completing the locking of the first clamps and the second clamps.

[0074] It is understandable that the number of the first through hole and the second through hole can be multiple, and the arrangement method can be variable, as long as the first through hole corresponds to the second through hole and the second through hole corresponds to the first through hole when stacked, which can increase the locking force between the first clamp and the second clamp.

[0075] It is understandable that part of the surface of the first clamp or part of the second clamp may also be provided with an arc groove for accommodating the tube, so that the first clamp or part of the second clamp is specifically used to fix the tube drag chain.

[0076] It can be understood that the thickness of the first locking portion of some of the first clamping parts is greater than the thickness of the first main body part, and the first locking portion is formed by the first main body part being bent and extended toward one side in the thickness direction to form a U-shaped structure; or, the thickness of the first locking portion of some of the first clamping parts is greater than the thickness of the first main body part, and the first locking portion is formed by the first main body part being bent and extended toward both sides in the thickness direction to form an I-shaped structure.

[0077] It can be understood that the thickness of the second locking portion of some second clamps is greater than the thickness of the second main body portion, and the second locking portion is formed by the second main body portion being bent and extended toward one side in the thickness direction to form a U-shaped structure; or, the thickness of the second locking portion is greater than the thickness of the second main body portion, and the second locking portion is formed by the second main body portion being bent and extended toward both sides in the thickness direction to form an I-shaped structure.

[0078] It is understandable that a third locking portion may be provided between the two first locking portions on the first main body of the first clamping member to form a W-shaped structure on the basis of the U-shaped structure, or a W-shaped structure on the basis of the I-shaped structure. The third locking portion is provided with at least one row of through holes penetrating in the thickness direction, or may be two rows or more, and the type and arrangement of the through holes in the through hole row are consistent with the through hole row on the first locking portion of the first clamping member;

[0079] It is understandable that a fourth locking portion is provided between the two second locking portions on the second main body portion of the second clamp, and a W-shaped structure is formed on the basis of the U-shaped structure, or a W-shaped structure is formed on the basis of the I-shaped structure. The fourth locking portion is provided corresponding to the third locking portion, and the fourth locking portion is provided with at least one row of through holes penetrating in the thickness direction, and may also be two rows or more, and the through hole type and arrangement method in the through hole row are consistent with the through hole row on the second locking portion of the second clamp.

[0080] The staggered overlapping locking clamp for cable and tube drag chains in one embodiment of the utility model may further include a support plate, the support plate having a plate-shaped third body portion and fifth locking portions located at opposite ends of the third body portion, the fifth locking portion being provided with a row of through holes penetrating in the thickness direction, the row of through holes including third positioning holes located at the head end and the tail end and at least one first through hole and at least one second through hole located between the two third positioning holes. The support plate may be stacked on the first clamp or on the second clamp.

[0081] When the support plate and the second clamp are stacked, the second positioning hole on the second clamp is arranged correspondingly to the third positioning hole on the support plate, the first through hole on the second clamp is arranged correspondingly to the second through hole on the support plate, and the second through hole on the second clamp is arranged correspondingly to the first through hole on the support plate.

[0082] When the first clamping member and the support plate are stacked, the third positioning hole on the support plate is arranged correspondingly to the first positioning hole on the first clamping member, the first through hole on the support plate is arranged correspondingly to the second through hole on the first clamping member, and the second through hole on the support plate is arranged correspondingly to the first through hole on the first clamping member.

[0083] The length of the third body part of the support plate in the extension direction of the through hole row is greater than the length of the first body part of the first clamp or the second body part of the second clamp in the extension direction of the through hole row. This arrangement enables the support plate to have a third body part with a larger area than the first clamp and the second clamp, which can effectively constrain the cable and tube to run within the designed trajectory and space, and even in high-speed movement, the software will not fly up or hit the support surface due to inertia.

[0084] The following describes in detail the staggered and iterative locking clamps for cable and tube drag chains of the present application through two specific embodiments to facilitate the understanding of the present application.

[0085] Embodiment 1:

[0086] like Figure 1 As shown, the staggered overlapping locking clamp for cable and tube drag chain in one embodiment of the utility model includes, from bottom to top, a stacked U-shaped first clamp 10a, an I-shaped second clamp 20, an I-shaped first clamp 10b, and a support plate 30. It also includes a plurality of fasteners 40 to lock the U-shaped first clamp 10a, the I-shaped second clamp 20, the I-shaped first clamp 10b, and the support plate 30 together. Among them, the U-shaped first clamp 10a, the I-shaped second clamp 20, and the I-shaped first clamp 10b have the same size.

[0087] like Figure 2 As shown, the U-shaped first clamping member 10a has a plate-shaped first main body portion 11 and first locking portions 12 located at opposite ends of the first main body portion 11. The thickness of the first locking portion 12 is greater than the thickness of the first main body portion 11. The first locking portion 12 is formed by bending and extending the first main body portion 11 toward one side in the thickness direction, thereby forming a U-shaped structure of the first clamping member 10a. The two first locking portions 12 have the same thickness and the heights protruding from the surface of the first main body portion 11 are also the same.

[0088] The first locking portion 12 is provided with a through hole row 13 penetrating in the thickness direction, and the through hole row 13 includes first positioning holes 131 at the head end and the tail end, and two first through holes A and two second through holes B located between the two first positioning holes 131.

[0090] The first body 11 has a plurality of arc grooves 111 formed on a side surface of the first locking portion 12. The arc grooves 111 are used to accommodate the row pipes to prevent the row pipes from being squeezed and deformed by the surface of the first body 11, thereby affecting the flow of the fluid therein.

[0091] like Figure 3 As shown, the I-shaped second clamping member 20 has a plate-shaped second main body portion 21 and second locking portions 22 located at opposite ends of the second main body portion 21. The thickness of the second locking portion 22 is greater than the thickness of the second main body portion 21. The second locking portion 22 is formed by bending and extending the second main body portion 21 toward both sides in the thickness direction, thereby forming an I-shaped structure of the second clamping member 20. The two second locking portions 22 have the same thickness and the heights protruding from the surface of the second main body portion 21 are also the same.

[0092] The second locking portion 22 is provided with a through hole row 23 penetrating in the thickness direction, and the through hole row 23 includes second positioning holes 231 at the head end and the tail end, and two first through holes A and two second through holes B located between the two second positioning holes 231. The two first through holes A are located between the two second through holes B.

[0093] The second positioning hole 231 is a countersunk hole. The first through hole A is a countersunk hole. The second through hole B is a threaded hole.

[0094] refer to Figure 1 As shown, the fastener 40 includes a cone head bolt, the length of which is greater than the thickness of the first locking portion 12 of the U-shaped first clamp 10a, but less than or equal to the sum of the thicknesses of the first locking portion 12 of the U-shaped first clamp 10a and the second locking portion 22 of the I-shaped second clamp 20.

[0095] When the I-shaped second clamp 20 is stacked on the U-shaped first clamp 10a, the second positioning hole 231 on the I-shaped second clamp 20 is arranged correspondingly to the first positioning hole 131 on the U-shaped first clamp 10a, the first through hole A on the I-shaped second clamp 20 is arranged correspondingly to the second through hole B on the U-shaped first clamp 10a, and the second through hole B on the I-shaped second clamp 20 is arranged correspondingly to the first through hole A on the U-shaped first clamp 10a. The cone head bolt is inserted from the first through hole A on the I-shaped second clamp 20 and is threadedly locked with the second through hole B on the U-shaped first clamp 10a to achieve the locking of the I-shaped second clamp 20 and the U-shaped first clamp 10a.

[0096] It can be understood that the head of the cone head bolt is completely sunk into the first through hole A in order not to affect the continued stacking of the subsequent first clamping member 10b.

[0097] like Figure 4 As shown, the I-shaped first clamping member 10b has a plate-shaped first main body portion 11 and first locking portions 12 located at opposite ends of the first main body portion 11. The thickness of the first locking portion 12 is greater than the thickness of the first main body portion 11. The first locking portion 12 is formed by bending and extending the first main body portion 11 toward both sides in the thickness direction, thereby forming the I-shaped structure of the first clamping member 10a. The two first locking portions 12 have the same thickness and the heights protruding from the surface of the first main body portion 11 are also the same.

[0098] The first locking portion 12 is provided with a through hole row 13 penetrating in the thickness direction, and the through hole row 13 includes first positioning holes 131 at the head end and the tail end, and two first through holes A and two second through holes B located between the two first positioning holes 131. The two second through holes B are located between the two first through holes A.

[0099] The first positioning hole 131 is a countersunk hole. The first through hole A is a countersunk hole. The second through hole B is a threaded hole.

[0100] refer to Figure 1 As shown, when the first fixture 10b of the type is stacked on the second fixture 20 of the type, the first positioning hole 131 on the first fixture 10b of the type is arranged correspondingly to the second positioning hole 231 on the second fixture 20 of the type, the first through hole A on the first fixture 10b of the type is arranged correspondingly to the second through hole B on the second fixture 20 of the type, and the second through hole B on the first fixture 10b of the type is arranged correspondingly to the first through hole A on the second fixture 20 of the type. The cone head bolt is inserted from the first through hole A on the first fixture 10b of the type, and is threadedly locked with the second through hole B on the second fixture 20 of the type, so as to realize the locking of the first fixture 10b of the type and the second fixture 20 of the type.

[0101] It can be understood that, in order not to affect the subsequent stacking of support plates, the head of the cone head bolt is completely sunk into the first through hole A.

[0102] like Figure 5 As shown, the support plate 30 has a plate-shaped third main body portion 31 and a fifth locking portion 32 located at opposite ends of the third main body portion 31, and the fifth locking portion 32 is provided with a row of through holes 33 penetrating in the thickness direction. The row of through holes 33 includes third positioning holes 331 located at the head end and the tail end and two first through holes A and two second through holes B located between the two third positioning holes 331.

[0103] The length of the third body part 31 of the support plate 30 in the extension direction of the through hole row 33 is greater than the length of the first body part 11 of the first fixture 10b of the tooling or the second body part 21 of the second fixture 20 of the tooling in the extension direction of the through hole row. Therefore, the extension length of the fifth locking part 32 is also lengthened, thereby forming a reinforcing rib. This arrangement enables the support plate 30 to have a third body part with a larger area than the first body part of the first fixture and the second body part of the second fixture, which can effectively constrain the cable and tube to run in the designed trajectory and space, and even in high-speed movement, the software will not fly up or hit the support surface due to inertia.

[0104] refer to Figure 1 As shown, the support plate 30 is stacked on the first fixture 10b of the type. The third positioning hole 331 on the support plate 30 is arranged corresponding to the first positioning hole 131 of the first fixture 10b of the type, the first through hole A on the support plate 30 is arranged corresponding to the second through hole B on the first fixture 10b of the type, and the second through hole B on the support plate 30 is arranged corresponding to the first through hole A on the first fixture 10b of the type. The cone head bolt is inserted from the first through hole A on the support plate 30 and is threadedly locked with the second through hole B on the first fixture 10b of the type, so as to achieve the locking of the support plate 30 and the first fixture 10b of the type.

[0105] The fastener 40 also includes a long cone head bolt, the length of which is greater than the sum of the thicknesses of the first locking portion of the first clamping member, the second locking portion of the second clamping member, and the fifth locking portion of the support member. The long cone head bolt is inserted from the third positioning hole of the support member, passes through the first positioning hole and the second positioning hole, and finally achieves locking and limiting with the component to be installed by the staggered overlapping locking clamp for the cable and tube drag chain of the utility model.

[0106] Embodiment 2:

[0107] The difference between the present embodiment 2 and the embodiment 1 is that in the present embodiment, a U-shaped first clamping member and a U-shaped second clamping member can be used to realize the stacking arrangement.

[0108] Embodiment 3:

[0109] like Figure 6 As shown, the staggered overlapping locking clamp for cable and tube drag chain in one embodiment of the utility model includes, from bottom to top, a stacked W-shaped second clamp 200a, a king-shaped first clamp 100, a king-shaped second clamp 200b, and a support plate 300. It also includes a plurality of fasteners 400 to lock the W-shaped second clamp 200a, the king-shaped first clamp 100, the king-shaped second clamp 200b, and the support plate 300 together. Among them, the W-shaped second clamp 200a, the king-shaped first clamp 100, and the king-shaped second clamp 200b have the same size.

[0110] like Figure 7 As shown, the W-shaped second clamp 200a has a plate-shaped second main body portion 210 and second locking portions 220 located at opposite ends of the second main body portion 210. A fourth locking portion 240 is provided on the second main body portion 210 between the two second locking portions 220. The thickness of the second locking portion 220 and the fourth locking portion 240 are both greater than the thickness of the second main body portion 210, and the second locking portion 220 and the fourth locking portion 240 are both formed by the second main body portion 210 being bent and extended toward the same side in the thickness direction, thereby forming a W-shaped structure of the second clamp. The two second locking portions 220 and the one fourth locking portion 240 have the same thickness, and the heights thereof protruding from the surface of the second main body portion 210 are also the same. The width of the fourth locking portion 240 may be equal to the sum of the widths of the two second locking portions 220.

[0111] The second locking portion 220 and the fourth locking portion 240 are both provided with a through hole row 230 penetrating in the thickness direction, and the through hole row 230 includes a second positioning hole 2310 located at the head end and the tail end, and two first through holes A and two second through holes B located between the two second positioning holes 2310. The two first through holes A are located between the two second through holes B. Among them, the fourth locking portion 240 is provided with two identical through hole rows 230, which can improve the strength after locking.

[0112] The second positioning hole 2310 is a countersunk hole. The first through hole A is a countersunk hole. The second through hole B is a threaded hole.

[0113] The second body 210 has a plurality of arc grooves 211 formed on a side surface of the second locking portion 220 that is concavely formed and parallel to the second locking portion 220. The arc grooves 211 are used to accommodate the row pipes to prevent the row pipes from being squeezed and deformed by the surface of the second body 210 and affecting the flow of the fluid therein.

[0114] like Figure 8As shown, the king-shaped first clamp 100 has a plate-shaped first main body portion 110 and first locking portions 120 located at opposite ends of the first main body portion 110. A third locking portion 140 is provided on the first main body portion 110 between the two first locking portions 120. The thickness of the first locking portion 120 and the third locking portion 140 are both greater than the thickness of the first main body portion 110. The first locking portion 120 and the third locking portion 140 are formed by bending and extending the first main body portion 110 toward both sides in the thickness direction, thereby forming the first clamp 100 into a king-shaped structure. The thickness of the two first locking portions 120 and the one third locking portion 140 are the same, and the heights thereof protruding from the surface of the first main body portion 110 are also the same. The width of the third locking portion 140 can be equal to the sum of the widths of the two first locking portions 120.

[0115] The first locking portion 120 and the third locking portion 140 are both provided with a through hole row 130 penetrating in the thickness direction, and the through hole row 130 includes a first positioning hole 1310 located at the head end and the tail end, and two first through holes A and two second through holes B located between the two first positioning holes 1310. The two second through holes B are located between the two first through holes A.

[0116] The first positioning hole 1310 is a countersunk hole. The first through hole A is a countersunk hole. The second through hole B is a threaded hole.

[0117] refer to Figure 6 As shown, the fastener 400 includes a cone head bolt, the length of which is greater than the thickness of the first locking portion 120 of the W-type first clamp 100, but less than or equal to the sum of the thicknesses of the first locking portion 120 of the W-type first clamp 100 and the second locking portion 220 of the W-type second clamp 200a.

[0118] When the first W-shaped clamp 100 is stacked on the second W-shaped clamp 200a, the first positioning hole 1310 on the first W-shaped clamp 100 is arranged correspondingly to the second positioning hole 2310 on the second W-shaped clamp 200a, the first through hole A on the first W-shaped clamp 100 is arranged correspondingly to the second through hole B on the second W-shaped clamp 200a, and the second through hole B on the first W-shaped clamp 100 is arranged correspondingly to the first through hole A on the second W-shaped clamp 200a. The cone head bolt is inserted from the first through hole A on the first W-shaped clamp 100 and is threadedly locked with the second through hole B on the second W-shaped clamp 200a, so as to realize the locking of the first I-shaped clamp 100 and the second W-shaped clamp 20.

[0119] It can be understood that the head of the cone head bolt is completely sunk into the first through hole A in order not to affect the subsequent stacking of the king-shaped second clamping member 200b.

[0120] like Fig. 9As shown, the king-shaped second clamp 200b has a plate-shaped second main body 210 and second locking parts 220 located at opposite ends of the second main body 210. A fourth locking part 240 is provided between the two second locking parts 220 on the second main body 210. The thickness of the second locking part 220 and the fourth locking part 240 are both greater than the thickness of the second main body 210. The second locking part 220 and the fourth locking part 240 are both formed by bending and extending the second main body 210 toward both sides in the thickness direction, thereby forming a king-shaped structure of the second clamp. The thickness of the two second locking parts 220 and the one fourth locking part 240 is the same, and the heights thereof protruding from the surface of the second main body 210 are also the same. The width of the fourth locking part 240 can be equal to the sum of the widths of the two second locking parts 220.

[0121] The second locking portion 220 and the fourth locking portion 240 are both provided with a through hole row 230 penetrating in the thickness direction, and the through hole row 230 includes a second positioning hole 2310 located at the head end and the tail end, and two first through holes A and two second through holes B located between the two second positioning holes 2310. The two first through holes A are located between the two second through holes B. Among them, the fourth locking portion 240 is provided with two identical through hole rows 230, which can improve the strength after locking.

[0122] The second positioning hole 231 is a countersunk hole. The first through hole A is a countersunk hole. The second through hole B is a threaded hole.

[0123] like Figure 6 As shown, when the king-shaped second clamp 200b is stacked on the king-shaped first clamp 100, the second positioning hole 2310 on the king-shaped second clamp 200b is arranged correspondingly to the first positioning hole 1310 on the king-shaped first clamp 100, the first through hole A on the king-shaped second clamp 200b is arranged correspondingly to the second through hole B on the king-shaped first clamp 100, and the second through hole B on the king-shaped second clamp 200b is arranged correspondingly to the first through hole A on the king-shaped first clamp 100. The cone head bolt is inserted from the first through hole A on the king-shaped second clamp 200b and is threadedly locked with the second through hole B on the king-shaped first clamp 100, so as to realize the locking of the king-shaped second clamp 200b and the king-shaped first clamp 100.

[0124] It can be understood that, in order not to affect the subsequent stacking of support plates, the head of the cone head bolt is completely sunk into the first through hole A.

[0125] like Fig.10As shown, the support plate 300 has a plate-shaped third body portion 310 and a fifth locking portion 320 located at two opposite ends of the third body portion 310. Similarly, a sixth locking portion 340 may be provided between the two fifth locking portions 320 on the third body portion 310 of the support plate 300. Both the fifth locking portion 320 and the sixth locking portion 340 are provided with a through hole row 330 penetrating in the thickness direction, and the through hole row 330 includes a third positioning hole 3310 located at the head end and the tail end, and two first through holes A and two second through holes B located between the two third positioning holes 3310.

[0126] The length of the third body part 310 of the support plate 300 in the extension direction of the through hole row 330 is greater than the length of the first body part 110 of the first fixture 100 or the second body part 210 of the second fixture 200b in the extension direction of the through hole row. Therefore, the extension length of the fifth locking part 32 is also lengthened, thereby forming a reinforcing rib. This arrangement enables the support plate 300 to have a third body part with a larger area than the first body part of the first fixture and the second body part of the second fixture, which can effectively constrain the cable and tube to run in the designed trajectory and space, and even in high-speed movement, the software will not fly up or hit the support surface due to inertia.

[0127] like Figure 6 As shown, the support plate 300 is stacked on the king-shaped second clamp 200b. The third positioning hole 3310 on the support plate 300 is arranged corresponding to the second positioning hole 2310 of the king-shaped second clamp 200b, the first through hole A on the support plate 300 is arranged corresponding to the second through hole B on the king-shaped second clamp 200b, and the second through hole B on the support plate 300 is arranged corresponding to the first through hole A on the king-shaped second clamp 200b. The cone head bolt is inserted from the first through hole A on the support plate 300 and is threadedly locked with the second through hole B on the king-shaped second clamp 200b to achieve locking of the support plate 300 and the king-shaped second clamp 200b.

[0128] The fastener 400 also includes a long cone head bolt, the length of which is greater than the sum of the thicknesses of the first locking portion of all the stacked first clamps, the second locking portion of the second clamps, and the fifth locking portion of the support. The long cone head bolt is inserted from the third positioning hole of the support, passes through the first positioning hole and the second positioning hole, and finally achieves locking and limiting with the component to be installed by the staggered overlapping locking clamp for cable and tube drag chain of the utility model.

[0129] The shapes of the first clamp and the second clamp can be divided into two categories: U-shaped (U-shaped single row / W-shaped double row) and I-shaped (I-shaped single row / double I-shaped double row). The U-shaped is mainly used for the outer layer, and the I-shaped is often used in the inner layer. When iterating, first the U-shaped mouth faces up, then install a layer of I-shaped, then install the I-shaped in sequence, and finally install the U-shaped support plate upside down. During each installation, a silicone cushion is used between the metal and the wire to effectively buffer the extrusion of the metal on the wire and increase the static friction to prevent cuts or core wire movement. Customizing the first clamp or the second clamp with an arc groove can effectively match the diameter of the trachea (exhaust pipe), ensuring that the trachea is effectively fixed and will not be flattened or cut. It can be used interchangeably and in combination according to the type and quantity of the flexible cable / exhaust pipe to be fastened.

[0130] The first clamp and the second clamp are machined from alloy materials and are specially coated. They are dust-free, wear-resistant, high in strength, highly interchangeable, and have strong enough locking force without damaging the wires. They have their own threads and staggered locking, which facilitates rapid production and iterative installation layer by layer.

[0131] The fastening part of the support plate has the same hole specifications as the first clamp and the second clamp, and they are compatible and interchangeable. The clamped wires are classified in the same way as the first clamp and the second clamp. The difference between the two is that the support plate has an extra part with a specially reinforced plate-shaped part, which can effectively restrain the flexible cable and tube to run smoothly within the specified design range, play a good role in supporting the drag chain and preventing the drag chain from warping and flying at high speed, and its force is more uniform and the resistance is more constant, ensuring the effective improvement of the repeatability of high-precision motion equipment.

[0132] The support plate adopts a rounded corner design and a sloped port. All corners of the first clamp and the second clamp are designed with arc-shaped rounded corners to ensure that the metal parts will not hurt people when the drag chain moves. A special material film is affixed to the contact surface with the wire to effectively reduce wear, buffer vibration, and prevent burrs from damaging the wire surface.

[0133] During assembly, the first clamp and the second clamp are staggered in sequence, and the staggered iteration can be achieved through the cone head bolts. You can also choose different U-shaped or I-shaped first and second clamps and support plates according to the design and arrangement requirements of the wires of the new drag chain to achieve the functions of clamping, fixing, lifting, binding and protecting all flexible cables / tubes.

[0134] For example, the U-shaped first clamp can be used as the first piece, and four positioning pins (long cone head bolts) are passed through the four countersunk holes fixed at the four corners in turn, and then the new cable arrangement and anti-slip protective layer are placed in, and then an "I-shaped" second clamp is stacked. After alternating one by one, one by two, and two by two in a regular pattern, when all the wires are assembled in sequence, the last piece is a U-shaped support piece to complete the assembly of one end of the entire new cable drag chain.

[0135] When the drag chain is fixed as a whole, long cone head bolts are used to fix the countersunk holes at both ends of each row (on the four corners). This way of fixing the drag chain symmetrically at four corners, i.e. fixing at four corners, can prevent the installation angle of the drag chain from being non-parallel or shaking with the running guide rail. The four corners have high force strength, uniform force, anti-torsion and warping, stable and no shaking.

[0136] The staggered locking clamp for cable and tube drag chains of the present application has the following advantages:

[0137] The four corner countersunk fixings replace the traditional middle flat head fixings in the industry, preventing the chain from swinging and ensuring the installation of parallel guide rails, while effectively reducing the height of the chain.

[0138] It comes with symmetrical staggered threaded holes and countersunk holes. Each layer is locked with four symmetrical cone-head bolts, which can effectively realize staggered installation and ensure connection strength and uniform force.

[0139] The combination of U-shape and I-shape can minimize the thickness of the clamp and ensure effective layering of cables, which is convenient for effectively controlling the tightness between layers of wires during assembly and facilitating the release of static friction.

[0140] The support plate is lengthened and the inner side is designed to be in contact with the wires in an arc shape. While strengthening the binding strength, it also guides and buffers the wires to prevent them from running off and shaking, and effectively absorbs the impact of contact vibration. The inner layer of the support plate can be covered with a wear-resistant film to prevent damage to the wires, absorb the vibration of the cable running, and prevent dust and pollution.

[0141] All parts are specially oxidized, no rust, no oxidation, no scratches, easy to clean. The dust-free cleanliness level can reach CLASS1 level.

[0142] Modular design, strong interchangeability, can achieve most of the flexible cable and tube specifications. Easy to produce and install, can use pneumatic tools for rapid batch production, maintenance and replacement are also convenient.

[0143] The machined nature of the part allows for the integration of special cables, such as optical fiber and other special cables, with customizable slots for secure installation and secure clamping.

[0144] The hole size is compatible with the fixed hole of the dedicated connector, effectively saving the space occupied by the connector and the drag chain for users.

[0145] Compared with the prior art, the staggered and iterative locking clamp for the cable and tube drag chain of the utility model can, through a scientific staggered and iterative locking design, reasonably fix the soft cables and tubes in layers during the assembly process, reasonably adjust the tightness of the cables, effectively reduce the bending and warping force of the drag chain and improve the stability of the running resistance.

[0146] The staggered and iterative locking clamp used for the cable and tube drag chain of the utility model has a staggered and iterative locking clamp structure in which the locking parts are arranged at staggered intervals for locking, and there are no iterative bolts, thereby effectively reducing the thickness of the clamp and thereby effectively reducing the height of the flexible cable / tube drag chain.

[0147] The staggered locking clamp for the cable and tube drag chain of the utility model adopts a support plate made of alloy material, which is fixed at four corners (third positioning hole), and the fifth locking part extends to the edge of the third main body part to form a reinforcing rib, which effectively restrains the cable and tube to run according to the designed trajectory and space. Even in high-speed movement, the software will not fly up or hit the supporting surface due to inertia.

[0148] The staggered and iterative locking clamp for the cable and tube drag chain of the utility model is manufactured by machine processing of alloy materials, and the thickness and hole positions of the parts are utilized to the extreme, which effectively ensures the strength while maximizing the passing density of effective pins and air pipes within the unit cross-sectional area of ​​the new cable drag chain.

[0149] The staggered overlapping locking clamp for the cable and tube arrangement drag chain of the utility model can fix the cables and tubes in layers and adjust the tightness so that the friction between the wire layers is very uniform, which effectively reduces the running resistance fluctuation of the moving new cable arrangement drag chain.

[0150] The staggered iterative locking clamp for the cable and tube drag chain of the utility model takes into account various wire sizes, unifies the sizes of parts and installation holes, and performs standard modular design. It is compatible with the changing implementation needs of many applications, facilitates mass production and rapid assembly requirements, saves design time and performance analysis and production cycle through modular mass production, and lays a foundation for large-scale cost reduction.
