Description

Technical Field

[0001] The present application relates to the field of clamping devices, and in particular to a clamping device and an automatic cable tie system. Background Art

[0002] The clamping device is used to clamp and fix objects. When the clamping device cooperates with objects of different sizes, the clamping force of the clamping device is often smaller for objects of smaller sizes, and greater for objects of larger sizes. Utility Model Content

[0003] In view of the above-mentioned technical problems, the purpose of the present application is to provide a clamping device capable of adjusting the clamping force, and an automatic cable tie system including the above-mentioned clamping device, which specifically includes the following technical solutions:

[0004] In the first aspect, an embodiment of the present application provides a clamping device, comprising a bracket, two clamping members, a supporting member and an elastic member, wherein the two clamping members are arranged at intervals, and at least one clamping member is slidably connected to the bracket along the arrangement direction of the two clamping members; the elastic member and the supporting member are arranged sequentially on one side of the two clamping members along the arrangement direction of the two clamping members, and the two ends of the elastic member are respectively supported by a clamping member and a supporting member, and the supporting member is slidably connected to the bracket to adjust the clamping force of the two clamping members.

[0005] At least one clamping member in the clamping device of the present application is slidably connected to the bracket. By adjusting the spacing between the two clamping members, objects of different sizes can be placed in the spacing, and then one clamping member is slid toward the other clamping member to clamp the object.

[0006] The clamping device of the present application includes a supporting member and an elastic member, wherein the elastic member is elastically connected between the supporting member and the clamping member. Adjusting the distance between the supporting member and the clamping member can change the elastic force of the elastic member, thereby adjusting the clamping force of the clamping member on the object to meet the needs of objects of different sizes and different clamping forces.

[0007] In one embodiment, the clamping device includes a screw rod, which is rotatably connected to one of the bracket or the abutment and is threadedly connected to the other of the bracket or the abutment to drive the abutment to slide relative to the bracket.

[0008] In this embodiment, the clamping device is connected between the bracket and the supporting member through a screw, and the screw is threadedly connected to one of the bracket and the supporting member. The rotation of the screw can drive the supporting member to slide along the length direction of the screw, thereby realizing the sliding of the supporting member relative to the bracket.

[0009] In one embodiment, at least one of the two clamping members includes a rotating part, which is rotatably connected to the body of the clamping member, and the rotating axis of the rotating part is perpendicular to the arrangement direction of the two clamping members, and the distance between the arc surface of one clamping member and the other clamping member is smaller than the distance between the body of the clamping member and the other clamping member.

[0010] In this embodiment, the clamping member is provided with a rotating part, which is closer to the other clamping member than the main body of the clamping member. When the two clamping members clamp an object, the rotating part abuts against the object. The rotating part rotates relative to the main body of the clamping member, and can drive the object to move in a direction perpendicular to the arrangement of the two clamping members.

[0011] In one embodiment, the rotating portion comprises a roller, and an axis of the roller coincides with the axis of the rotating portion.

[0012] In this embodiment, the rotating part may include a roller. When the two clamping members clamp an object, the roller abuts against the object, thereby driving the object to move in a direction perpendicular to the arrangement of the two clamping members.

[0013] In one embodiment, the two clamping members each include a rotating portion, and the rotating axes of the two rotating portions are parallel to each other and arranged at intervals.

[0014] In this embodiment, when the two clamping members are clamped, the rotating parts of the two clamping members abut against the article, and the rotating axes of the two rotating parts are parallel to each other and arranged at intervals, so that the article can be driven by the two rotating parts together and move in a direction perpendicular to the arrangement of the two clamping members. At the same time, since the clamping force of the clamping member can be adjusted according to the abutting member, when the two abutting members are elastically connected to the two clamping members respectively, adjusting the clamping force of the clamping member on the article can ensure that the article is subjected to the same pressure on both sides during the movement, thereby ensuring the movement path of the article.

[0015] In one embodiment, the clamping device includes a transmission assembly, which is transmission-connected between two rotating parts. One rotating part rotates and drives the other rotating part to rotate in the opposite direction through the transmission assembly.

[0016] In this embodiment, one rotating part drives another rotating part to rotate through a transmission assembly, and the two rotating parts rotate in opposite directions, so that the object can move in a direction perpendicular to the arrangement of the two clamping members.

[0017] In one embodiment, the transmission assembly includes two gears, which are respectively fixed to the two rotating parts, and the rotating axes of the two gears coincide with the rotating axes of the two rotating parts respectively. When the clamp slides relative to the bracket, the two gears mesh with each other.

[0018] In this embodiment, the transmission assembly includes two gears, which are meshed with each other. One rotating part rotates and transmits power to the other rotating part through the meshing between the gears. The other rotating part rotates in the opposite direction driven by the gears, so that the object can move in a direction perpendicular to the arrangement of the two clamping parts.

[0019] In one embodiment, the roller is provided with a guide groove, which is arranged around the side wall of the roller, and the guide groove is used to accommodate objects and limit the movement direction of the objects.

[0020] In this embodiment, the side wall of the roller is provided with a guide groove, and part of the object is received in the guide groove, so that the object can move in a direction perpendicular to the arrangement of the two clamping members, and prevent the object from moving in other directions relative to the clamping members.

[0021] In one embodiment, the clamping device includes a friction pad fixed to two opposing sides of the two clamping members to increase the friction on the surfaces of the clamping members.

[0022] In this embodiment, a friction pad is provided on the surface of the clamping member to increase the friction between the clamping member and the object, thereby avoiding insufficient friction when the clamping member clamps the object, and ensuring that the clamping member can clamp and fix the object. At the same time, when the clamping member includes a roller, the friction pad can also be provided around the side wall of the roller to avoid slipping when the roller drives the object to move.

[0023] In a second aspect, the present application also provides an automatic cable tie system, including a guide groove and the above-mentioned clamping device, the guide groove is used to accommodate the cable tie, the bracket of the clamping member is slidably connected to the guide groove, and the clamping device clamps the cable tie and drives the cable tie to slide along the guide groove.

[0024] It can be understood that the automatic cable tie system of the present application can clamp cable ties of different sizes and adjust the clamping force of the clamping device on the cable ties because it adopts the above-mentioned clamping device. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the directional terms used are for better and clearer explanation and understanding of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0037] The present application provides an automatic cable tie system, including a guide groove and a clamping device, wherein the guide groove is used to receive the cable tie, a bracket of the clamping device is slidably connected to the guide groove, and the clamping device can clamp the cable tie and drive the cable tie to slide along the guide groove. The guide groove can be arranged to extend along an arc, the head of the cable tie is fixed to the guide groove, the tail of the cable tie is fixed to the clamping device, and the clamping device moves relative to the guide groove so that the tail of the cable tie passes through the buckle of the head of the cable tie, thereby completing the steps of automatic cable tie.

[0038] See also Figure 1-Figure 3 ,in, Figure 1 A schematic diagram of the exploded structure of a clamping device 100 provided in one embodiment of the present application is illustrated; Figure 2 A partial structural schematic diagram of a clamping device 100 provided in one embodiment of the present application is illustrated; Figure 3 A perspective structural diagram of a clamping device 100 provided in an embodiment of the present application is illustrated.

[0039] The present application provides a clamping device 100, including a bracket 10, two clamping members 20, a supporting member 40 and an elastic member 30, wherein the two clamping members 20 are arranged at intervals, and at least one clamping member 20 is slidably connected to the bracket 10 along the arrangement direction of the two clamping members 20.

[0040] Specifically, in one embodiment, Figure 1 As shown, the clamping member 20 includes a first clamping member 21 and a second clamping member 22, the first clamping member 21 and the second clamping member 22 are spaced apart from each other, the second clamping member 22 is slidably connected to the bracket 10, and the second clamping member 22 can slide relative to the bracket 10 along the arrangement direction of the first clamping member 21 and the second clamping member 22, so that the spacing between the first clamping member 21 and the second clamping member 22 changes. When it is necessary to clamp an object, the second clamping member 22 moves toward the direction of the first clamping member 21 to reduce the gap therebetween, so that the clamping member 20 clamps the object; when it is necessary to release the object, the second clamping member moves toward the direction away from the first clamping member 21 to increase the gap therebetween, so as to release the object.

[0041] The elastic member 30 and the supporting member 40 of the clamping device 100 of the present application are arranged in sequence on one side of the two clamping members 20 along the arrangement direction of the two clamping members 20, and the two ends of the elastic member 30 are respectively supported by a clamping member 20 and a supporting member 40, and the supporting member 40 is slidably connected to the bracket 10 to adjust the clamping force of the two clamping members 20.

[0042] Specifically, in one embodiment, Figure 2 and Figure 3 As shown, the two abutting members 40 are located on the side of the second clamping member 22 away from the first clamping member 21, and the two elastic members 30 are located between the abutting members 40 and the second clamping member 22. The two ends of the elastic member 30 respectively abut against the second clamping member 22 and the abutting members 40, so that the abutting members 40 are elastically connected to the second clamping member 22. The abutting members 40 can slide relative to the bracket 10 along the arrangement direction of the first clamping member 21 and the second clamping member 22, so that the elastic force of the elastic member 30 can be changed by the distance between the abutting members 40 and the second clamping member 22, thereby realizing the adjustment of the clamping force between the first clamping member 21 and the second clamping member 22.

[0043] In the existing clamping device, the spacing between the clamping parts in the clamping device is relatively fixed, which makes it difficult to adapt to objects of different sizes. For example, the clamping force for smaller objects is smaller, and the clamping force for larger objects is greater. At the same time, the existing clamping device cannot adjust the clamping force of the clamping device according to objects of different sizes. When the clamping force is insufficient, it is often necessary to reduce the spacing between the clamping parts to increase the clamping force, which makes it difficult to accurately adjust the clamping force and easily damages the object.

[0044] At least one clamping member 20 in the clamping device 100 of the present application is slidably connected to the bracket 10. By adjusting the spacing between the two clamping members 20, objects of different sizes can be placed in the spacing, and then one clamping member 20 is slid toward the other clamping member 20 to clamp the object.

[0045] The clamping device 100 of the present application includes a support member 40 and an elastic member 30. The elastic member 30 is elastically connected between the support member 40 and the clamping member 20. Adjusting the distance between the support member 40 and the clamping member 20 can change the elastic force of the elastic member 30, thereby adjusting the clamping force of the clamping member 20 on the object, so as to meet the requirements of objects of different sizes and different clamping forces. It can be understood that the clamping force of the clamping device 100 of the present application can be directly determined by the length of the elastic member 30.

[0046] Meanwhile, for the clamping device for clamping the cable tie, the existing clamping device has a complex structure, has more parts, has more manufacturing and assembly processes, and has more parts, making it more difficult to ensure the normal operation of the clamping device.

[0047] The clamping device 100 of the present application has a simple structure, and only has two clamping members 20 and a supporting member 40 and an elastic member 30 for controlling the clamping force between the clamping members 20. It has fewer manufacturing and assembly steps, and it is also easier to realize the action of clamping the object by the clamping device 100.

[0048] The automatic cable tie system including the clamping device 100 of the present application can clamp and fix the cable tie through the clamping device 100, and the spacing between the clamping devices 100 can be adjusted to accommodate cable ties of different sizes. At the same time, the clamping device 100 can adjust the clamping force on the cable tie so that there is enough friction between the clamping device 100 and the cable tie to fix the cable tie, avoid slipping caused by insufficient friction between the cable tie and the clamping member 20, and then drive the cable tie to slide relative to the guide groove.

[0049] In addition, after the tail of the cable tie passes through the buckle of the head of the cable tie, the clamping device 100 can continue to drive the tail of the cable tie to move relative to the guide groove, so that the size of the cable tie loop formed by the cable tie is reduced, thereby tightening the cable tie.

[0050] It can be understood that the clamping device 100 of the present application can not only be used to clamp and fix the tail of the cable tie, but also drive the tail of the cable tie to pass through the buckle of the head of the cable tie. In another embodiment, the clamping device 100 can also clamp and fix the head of the cable tie, and drive the head of the cable tie to move so that the tail of the cable tie passes through the buckle of the head of the cable tie. In another embodiment, the automatic cable tie system is provided with two clamping devices 100, which can also clamp and fix the head and tail of the cable tie at the same time, so that the tail of the cable tie moves relative to the head of the cable tie, and can also make the tail of the cable tie pass through the buckle of the head of the cable tie.

[0051] In other embodiments, the clamping device 100 can also clamp other positions of the cable tie to assist in fixing the cable tie to the guide groove.

[0052] It should be pointed out that the clamping device 100 of the present application can not only be used in automatic cable tie systems to clamp and fix cable ties, but can also be used in other systems or devices that need to fix objects. Compared with other clamping devices, the clamping device 100 of the present application can adjust the spacing between the clamping members 20 and the clamping force to adapt to objects of different sizes.

[0053] In one embodiment, the clamping device 100 includes a screw rod that is rotatably connected to one of the bracket 10 or the abutment 40 and threadedly connected to the other of the bracket 10 or the abutment 40 to drive the abutment 40 to slide relative to the bracket 10 .

[0054] In one embodiment, the screw of the clamping device 100 is fixedly connected to the abutment 40 , and the screw is threadedly connected to the bracket 10 . The screw rotates to drive the abutment 40 to slide relative to the bracket 10 .

[0055] In one embodiment, if Figure 1-Figure 3 As shown, the bracket 10 includes a threaded hole, and the supporting member 40 includes a screw, which is fixedly connected to the body of the supporting member 40. The screw is at least partially located in the threaded hole. The screw rotates to drive the body of the supporting member 40 to slide relative to the bracket 10 along the arrangement direction of the first clamping member 21 and the second clamping member 22 to change the length of the elastic member 30, thereby adjusting the clamping force between the two clamping members 20.

[0056] In one embodiment, at least one of the clamping members 20 includes a rotating portion, which is rotatably connected to the body of the clamping member 20, and the rotating axis of the rotating portion is perpendicular to the arrangement direction of the two clamping members, and the distance between the arc surface of one clamping member 20 and the other clamping member 20 is smaller than the distance between the body of the clamping member 20 and the other clamping member 20. Compared with the body of the clamping member 20, the rotating portion is closer to the other clamping member 20. When the two clamping members 20 clamp an object, the rotating portion abuts against the object, and the rotating portion rotates relative to the body of the clamping member 20, which can drive the object to move in a direction perpendicular to the arrangement of the two clamping members 20.

[0057] In one embodiment, if Figure 2 As shown, the clamping device 100 includes a bearing 70, the axis of the bearing 70 is perpendicular to the arrangement direction of the first clamping member 21 and the second clamping member 22, the inner ring of the bearing 70 is rotatably connected to the clamping member 20, and the outer ring of the bearing 70 is slidably connected to the bracket 10, and the sliding direction is along the arrangement direction of the first clamping member 21 and the second clamping member 22, so that the clamping member 20 can clamp the object, and the clamping member 20 can rotate relative to the bracket 10 to drive the object to move in a direction perpendicular to the first clamping member 21 and the second clamping member 22.

[0058] In one embodiment, the clamping device 100 of the present application is applied to an automatic cable tie system. Since the rotating portion of the clamping device 100 can drive the object to slide relative to the bracket 10, the bracket of the clamping device 100 can be directly fixedly connected to the guide groove. The clamping device 100 can drive the tail of the cable tie to move along the extension direction of the guide groove and pass through the buckle of the head of the cable tie, thereby realizing automatic cable tie.

[0059] In one embodiment, the rotating portion of the clamping member 20 includes a roller, and the axis of the roller coincides with the rotation axis of the rotating portion.

[0060] In one embodiment, one of the first clamping member 21 and the second clamping member 22 includes a roller, the axis of the roller coincides with the axis of the bearing 70, the roller can rotate relative to the bracket 10, and the roller slides to reduce the distance between the two rollers so that the clamping member 20 can clamp the object. The rotation of one roller can drive the object to move in a direction perpendicular to the first clamping member 21 and the second clamping member 22.

[0061] In one embodiment, the two clamping members 20 each include a rotating part, and the rotating axes of the two rotating parts are parallel to each other and arranged at intervals. The rotating axes of the two rotating parts are parallel to each other and arranged at intervals, so that the object can be driven by the two rotating parts together and move in a direction perpendicular to the arrangement of the two clamping members. At the same time, since the clamping force of the clamping member can be adjusted according to the abutting member, when the two abutting members are elastically connected to the two clamping members respectively, adjusting the clamping force of the clamping member on the object can ensure that the object is subjected to the same pressure on both sides during the movement, thereby ensuring the movement path of the object.

[0062] It is understandable that when the clamping force is large and only one rotating part drives the object to move, the large friction between the other clamping member 20 without a rotating part and the object may hinder the movement of the object, making it difficult to control the movement path of the object. Compared with only one rotating part of the two clamping members 20 driving the object to move, it is easier to control the movement path of the object by providing rotating parts on both clamping members 20, and thus the following preferred embodiments are provided:

[0063] In a preferred embodiment, Figure 2 As described above, the first clamping member 21 and the second clamping member 22 both include rollers, the axes of the rollers coincide with the axes of the bearing 70, the rollers can rotate relative to the bracket 10, the two rollers slide to reduce the distance between the two rollers so that the clamping member 20 can clamp the object, and the rotation of the two rollers can drive the object to move in a direction perpendicular to the first clamping member 21 and the second clamping member 22.

[0064] In one embodiment, the clamping device 100 includes a transmission assembly 50, which is transmission-connected between two rotating parts, and one rotating part rotates and drives the other rotating part to rotate in the opposite direction through the transmission assembly 50. One rotating part drives the other rotating part to rotate through the transmission assembly 50, and the rotation directions of the two rotating parts are opposite, so that the object can move in a direction perpendicular to the arrangement of the two clamping members 20.

[0065] In one embodiment, if Figure 2 As shown, the first clamping member 21 and the second clamping member 22 are connected by a transmission assembly 50, and the rotation of the first clamping member 21 or the second clamping member 22 can drive the second clamping member 22 or the first clamping member 21 to rotate in the opposite direction. The first clamping member 21 rotates in the opposite direction to the second clamping member 22, so that the object between the two clamping members 20 moves in a direction perpendicular to the arrangement direction of the two clamping members 20.

[0066] See also Figure 4-Figure 7 ,in, Figure 4 A schematic cross-sectional structure diagram of a clamping device 100 provided in an embodiment of the present application is shown; Figure 5A schematic structural diagram of a clamping device 100 provided in one embodiment of the present application is shown; Figure 6 A partial structural schematic diagram of a clamping device 100 provided in one embodiment of the present application is illustrated; Figure 7 A partial structural schematic diagram of a clamping device 100 provided in an embodiment of the present application is illustrated.

[0067] In one embodiment, the transmission assembly 50 includes two gears, which are respectively fixed to the two rotating parts, and the rotating axes of the two gears coincide with the rotating axes of the two rotating parts respectively. When the clamping member 20 slides relative to the bracket 10, the two gears mesh with each other.

[0068] It should be pointed out that at least one of the two clamping members 20 is slidably connected to the bracket 10, and the sliding of the clamping members 20 changes the distance between the two clamping members 20. When the sliding stroke of the clamping members 20 is too large, the center distance between the two gears is too large, so that the two gears cannot mesh with each other, thereby causing the transmission assembly 50 to fail, and the two clamping members 20 cannot rotate at the same time to drive the movement of the object.

[0069] In one embodiment, if Figure 4 and Figure 5 As shown, a first gear 51 is fixed to one end of the first clamping member 21, and a second gear 52 is fixed to one end of the second clamping member 22. The first gear 51 and the second gear 52 are both located outside the bracket 10, and the first gear 51 and the second gear 52 are meshed with each other. When the second clamping member 22 slides relative to the bracket 10, the first gear 51 and the second gear 52 always remain in meshing state, thereby ensuring the rotation of the first clamping member 21 and the second clamping member 22.

[0070] In this embodiment, when the second clamping member 22 slides so that the distance between the two clamping members 20 is too large, the center distance between the first gear 51 and the second gear 52 is large, resulting in the first gear 51 and the second gear 52 being unable to mesh. In order to ensure that the first gear 51 and the second gear 52 always remain in meshing state during the sliding process of the second clamping member 22 relative to the bracket 10, the second clamping member 22 is allowed to slide in a smaller range.

[0071] In one embodiment, the clamping device 100 is used to clamp the cable tie along its width direction. Different types of cable ties have small size variations. Even if the second clamping member 22 allows a small sliding range, it can still clamp the cable tie and drive the cable tie to move relative to each other.

[0072] In another embodiment, the clamping device 100 of the present application is used to clamp the cable tie along the thickness direction of the cable tie. The thickness range of the cable tie is 1.0mm-2.0mm, and the size variation of different types of cable ties is small. Even if the second clamping member 22 allows a small sliding range, it can still clamp the cable tie and drive the cable tie to move relative to each other.

[0073] It can be understood that the range of the spacing between the two clamping members 20 is related to the size of the first gear 51 and the second gear 52. When the tooth height of the first gear 51 and / or the second gear 52 is larger, the range of the spacing between the two clamping members 20 is also larger, and more sizes of items can be accommodated.

[0074] For the above two embodiments, compared with clamping the cable tie along the width direction, clamping the cable tie along the thickness direction can make the teeth of the cable tie contact with the clamping member 20, thereby increasing the friction between the cable tie and the clamping member 20, making it easier to clamp the cable tie and drive the cable tie to move.

[0075] In a preferred embodiment, Figure 2 As shown, the clamping device 100 includes a driving wheel 60, which is fixedly connected to the first clamping member 21. The rotation of the driving wheel 60 can drive the first clamping member 21 to rotate relative to the bracket 10, and drive the second clamping member 22 to rotate in the opposite direction through the first gear 51 and the second gear 52, thereby realizing the movement of the object located between the two clamping members 20 along the arrangement direction perpendicular to the two clamping members 20.

[0076] In one embodiment, the driving wheel 60 is transmission-connected to a motor, and the motor drives the driving wheel 60 to rotate. In other embodiments, the driving wheel may be transmission-connected to other driving components to enable the driving wheel 60 to rotate.

[0077] In one embodiment, the clamping device 100 includes a friction pad, which is fixed to the two sides of the two clamping members 20 facing each other to increase the friction on the surface of the clamping members 20. By arranging the friction pad on the surface of the clamping member 20 to increase the friction between the clamping member 20 and the object, insufficient friction when the clamping member 20 clamps the object is avoided, ensuring that the clamping member 20 can clamp and fix the object.

[0078] In another embodiment, the clamping member 20 includes a rotating portion, and fixing the friction pad to the surface of the rotating portion can also increase the friction between the clamping member 20 and the object, thereby preventing the object from slipping when the clamping member 20 moves the object.

[0079] In another embodiment, the clamping member 20 includes a roller, and the friction pad may be further disposed around the side wall of the roller, which may also increase the friction between the clamping member 20 and the object and prevent the object from slipping when the roller drives the object to move.

[0080] See also Figure 8 A partial structural diagram of a clamping member 20 provided in one embodiment of the present application is shown.

[0081] In one embodiment, if Figure 8 As shown, the clamping member 20 includes a roller, and the surface of the roller is provided with teeth. The teeth on the surface of the roller can contact with the teeth of the cable tie, thereby increasing the friction between the clamping member 20 and the object, avoiding the clamping member 20 from slipping when driving the cable tie, and ensuring the normal operation of the automatic cable tie system.

[0082] In one embodiment, if Figure 6 As shown, the clamping device 100 includes a washer 80. Along the rotation axis of the first clamping member 21, bearings 70 are provided on both sides of the first clamping member 21 to enable the first clamping member 21 to be rotatably connected to the bracket 10. The driving wheel 60 and the first gear 51 are also respectively located on both sides of the first clamping member 21. Two washers 80 are respectively located between the driving wheel 60 and the bearing 70 on the side facing the driving wheel 60 and between the first gear 51 and the bearing 70 on the side facing the first gear 51, so as to separate the driving wheel 60 from the bracket 10 and the first gear 51 from the bracket 10, so as to prevent the bracket 10 from affecting the rotation of the driving wheel 60 and the first gear 51.
