Description

Technical Field

[0001] The invention relates to the technical field of wire harness clamping, and in particular to a wire clamping and centering device. Background Art

[0002] Ultrasonic welding is usually used between the wire harness and the terminal. During welding, the wire harness is soft and prone to bending and deformation. In order to make the welding end of the wire harness located in the center of the welding area, the wire harness needs to be clamped by a wire clamping tool. However, the existing wire clamping tool may not clamp the wire in the center, which leads to inconsistency between the center of the wire harness and the center of the terminal, resulting in an eccentric welding area, which in turn affects the welding quality. Summary of the invention

[0003] The purpose of the present invention is to propose a wire clamping and centering device, which solves the technical problem in the prior art that the wire clamping tooling does not clamp the wire harness in the center, resulting in inconsistency between the center of the wire harness and the center of the terminal, resulting in eccentricity of the welding area, and thus affecting the welding quality.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0005] The present invention provides a wire clamping and centering device, comprising:

[0006] A driving mechanism, wherein the output end of the driving mechanism is connected to at least two groups of clamping assemblies in a transmission manner, and a clamping space for the wire harness is formed between each group of the clamping assemblies. The driving mechanism is configured to be able to drive at least two groups of the clamping assemblies to move closer or farther synchronously to reduce or expand the clamping space.

[0007] The wire clamping and centering device drives at least two groups of clamping components through a driving mechanism, and a clamping space for the wire harness is formed between each group of clamping components. The wire harness is placed in the clamping space, and the driving mechanism drives at least two groups of clamping components to move closer or farther away synchronously. When each group of clamping components approaches each other, the size of the clamping space is reduced, so that the wire harness is clamped in the center, avoiding the eccentricity of the welding area caused by the inconsistency between the center of the wire harness and the center of the terminal, thereby improving the welding quality.

[0008] As a preferred solution of the above-mentioned wire clamping and centering device, the wire clamping and centering device comprises two sets of clamping assemblies arranged opposite to each other, wherein the clamping assembly is a first clamping jaw assembly, and the wire clamping and centering device further comprises:

[0011] The driving mechanism is a first driving mechanism, which is installed on the first mounting seat. The output end of the first driving mechanism is transmission-connected to the two groups of sliders. The output end of the first driving mechanism can move in a second direction to drive the two groups of sliders to move along the first direction, so as to drive the two groups of the first clamping jaw assemblies to move closer to or away from each other along the first direction, wherein the second direction is perpendicular to the first direction.

[0012] The two groups of sliders of the wire clamping and centering device are slidably arranged on the first mounting seat along the first direction, and are moved along the second direction by the output end of the first driving mechanism to drive the two groups of sliders to move along the first direction, so as to drive the two groups of first clamping jaw assemblies to approach or move away from each other along the first direction, so as to clamp the wire harness and center the wire harness so that the center of the wire harness is consistent with the center of the terminal.

[0013] As a preferred solution of the above-mentioned wire clamping and centering device, the slider is provided with a first inclined guide track which is at an angle to the second direction, the inclination directions of the first inclined guide tracks on the two sliders are opposite, and the output end of the first driving mechanism is passed through the first inclined guide tracks of the two groups of sliders through a pin shaft, and the pin shaft can move along the first inclined guide track.

[0014] Through the design of the first inclined guide rail, the movement of the output end of the first drive mechanism along the second direction can be converted into the movement of the slider along the first direction, thereby driving the two groups of sliders to move closer to or away from each other along the first direction. The transmission method is cleverly designed, which reduces the driving requirements for the first drive mechanism.

[0015] As a preferred solution of the above-mentioned clamping and centering device, two groups of the sliders are stacked up and down, the slider located at the bottom is the first slider, and the slider located at the top is the second slider, the first mounting seat is provided with a first guide groove extending along the first direction, and the first slider is slidably arranged in the first guide groove;

[0024] The driving mechanism is a second driving mechanism, the output end of the second driving mechanism is connected to two groups of the second clamping jaw assemblies, and the second driving mechanism is used to drive the two groups of the second clamping jaw assemblies to move closer to or farther from each other along a first direction;

[0025] The support seat is movably mounted on the two groups of the second clamping jaw assemblies and is located between the two groups of the second clamping jaw assemblies. The support seat is used to support the wire harness. The two groups of the second clamping jaw assemblies move closer to or farther from each other to drive the support seat to rise and fall.

[0026] The wire clamping and centering device drives the two groups of second clamping jaw assemblies to move closer to or farther from each other along a first direction through a second driving mechanism, and drives the supporting seat to rise and fall. The two groups of second clamping jaw assemblies cooperate with the supporting group to clamp the wire harness and center the wire harness. When the two groups of second clamping jaw assemblies move closer to or farther from each other, the supporting seat can be driven to rise and fall. When the wire harness is clamped, the supporting seat can play a role of supporting the wire harness, so that the center of the wire harness is consistent with the center of the terminal.

The connecting shafts of the two groups of the second clamping jaw assemblies are respectively passed through one group of the second inclined guide track, and the connecting shaft can move along the corresponding second inclined guide track.

[0030] Through the cooperation between the second inclined guide track on the supporting seat and the connecting shaft of the second clamping jaw assembly, the clamping jaw assemblies can synchronously drive the supporting seat to rise and fall when they move closer to or away from each other. The structural design of the supporting seat is relatively ingenious.

[0038] The setting of the guide base enables the second mounting base to move along the second direction, so as to adjust the position of the second mounting base and the structure thereon to avoid interference with other structures.

[0059] Ultrasonic welding is usually used between the wire harness and the terminal. During welding, the wire harness is soft and prone to bending and deformation. In order to make the welding end of the wire harness located in the center of the welding area, the wire harness needs to be clamped by a wire clamping centering device. However, the existing wire clamping tooling may not be clamped in the center, which leads to inconsistency between the center of the wire harness and the center of the terminal, resulting in eccentricity of the welding area, which in turn affects the welding quality.

[0060] Embodiment 1

[0061] In order to solve the above problems, this embodiment provides a wire clamping and centering device, which includes a driving mechanism, the output end of the driving mechanism is connected to at least two groups of clamping components, and a clamping space for the wire harness is formed between each group of clamping components. The driving mechanism can drive at least two groups of clamping components to move closer or farther together to reduce or expand the clamping space. The wire harness is placed in the clamping space, and when each group of clamping components moves closer to each other, the size of the clamping space is reduced, so that the wire harness is clamped in the center, avoiding the eccentricity of the welding area caused by the inconsistency between the center of the wire harness and the center of the terminal, thereby improving the welding quality.

[0062] Specifically, Figure 1-Figure 4 As shown, the line clamping and centering device includes two groups of clamping assemblies arranged opposite to each other, the clamping assemblies are first clamping jaw assemblies 13, and the line clamping and centering device also includes a first mounting seat 11 and a slider, the two groups of sliders are slidably arranged on the first mounting seat 11 along the first direction, and each group of sliders is connected to a group of first clamping jaw assemblies 13. In this embodiment, the driving mechanism is a first driving mechanism 14, the first driving mechanism 14 is installed on the first mounting seat 11, the output end of the first driving mechanism 14 is transmission-connected with the two groups of sliders, and the output end of the first driving mechanism 14 can move in the second direction to drive the two groups of sliders to move along the first direction, thereby driving the two groups of first clamping jaw assemblies 13 to move closer to or away from each other along the first direction, wherein the second direction is perpendicular to the first direction.

[0063] The two groups of sliders of the wire clamping and centering device are slidably arranged on the first mounting seat 11 along the first direction, and are moved along the second direction by the output end of the first driving mechanism 14 to drive the two groups of sliders to move along the first direction, so as to drive the two groups of first clamping jaw assemblies 13 to synchronously approach or move away from each other along the first direction, so as to clamp the wire harness and center the wire harness so that the center of the wire harness is consistent with the center of the terminal.

[0064] Specifically, the slider is provided with a first inclined guide track 120 which is at an angle to the second direction, and the first inclined guide tracks 120 on the two sliders are inclined in opposite directions. A pin 141 is provided on the output end of the first driving mechanism 14, and the pin 141 is inserted into the first inclined guide tracks 120 of the two groups of sliders, and the pin 141 can move along the first inclined guide track 120. Through the design of the first inclined guide track 120, the movement of the output end of the first driving mechanism 14 along the second direction can be converted into the movement of the slider along the first direction, thereby driving the two groups of sliders to approach or move away from each other along the first direction, and then driving the two groups of first clamping jaw assemblies 13 to approach or move away from each other along the first direction, so as to achieve the clamping and loosening of the wire harness by the two groups of first clamping jaw assemblies 13. The transmission mode is cleverly designed, which reduces the driving requirements for the first driving mechanism 14.

[0065] Optionally, a first guide groove 111 extending along the first direction is provided on the first mounting seat 11, and one of the two groups of sliders is slidably set in the first guide groove 111, and the slider is the first slider 121. The first guide groove 111 can enable the first slider 121 to move along the first direction to avoid the first slider 121 from deflecting during the movement; a stopper is provided on the first slider 121, and a second guide groove 123 is formed between the stopper and the first mounting seat 11, and the second guide groove 123 extends along the first direction. The second guide groove 123 and the first guide groove 111 are overlapped with each other, and the other group of sliders in the two groups of sliders is slidably set in the second guide groove 123, and the slider is the second slider 122. The second guide groove 123 can enable the second slider 122 to move along the first direction to avoid the second slider 122 from deflecting during the movement.

[0066] Further, the first slider 121 includes a first slider body 1211 and a first displacement seat 1212. The first slider body 1211 is slidably disposed in the first guide groove 111. The first slider body 1211 is provided with a first inclined guide track 120. In this embodiment, the first inclined guide track 120 is an inclined guide groove. The pin 141 is penetrated in the inclined guide groove. The first displacement seat 1212 is connected to the first slider body 1211. The first displacement seat 1212 is connected to a group of first clamping jaw assemblies 13. The first displacement seat 1212 is used to support and fix a group of first clamping jaw assemblies 13. The first displacement seat 1212 forms the above-mentioned stopper, and a second guide groove 123 is formed between the first displacement seat 1212 and the first mounting seat 11. The second slider 122 includes a second slider body 1221 and a second displacement seat 1222. The second slider body 1221 is located above the first slider body 1211. The second slider body 1221 is slidably arranged in the second guide groove 123. The second slider body 1221 is provided with a first inclined guide track 120. The first inclined guide track 120 is an inclined guide groove. The inclined directions of the inclined guide grooves on the first slider body 1211 and the second slider body 1221 are opposite. The second displacement seat 1222 is arranged opposite to the first displacement seat 1212. The second displacement seat 1222 is connected to another group of first clamping jaw assemblies 13. The second displacement seat 1222 is used to support and fix the first clamping jaw assembly 13.

[0067] In this embodiment, the first clamping jaw assembly 13 is a V-shaped structure, and two groups of first clamping jaw assemblies 13 are arranged opposite to each other, and the wire harness is clamped by the inclined surface of the V-shaped structure. The structure of the first clamping jaw assembly 13 is simple and easy to prepare. When the two groups of first clamping jaw assemblies 13 are close to each other, the V-shaped structure allows the wire harness to be adjusted along the inclined surface of the V-shaped structure, so that the wire harness is centrally positioned and clamped.

[0068] Optionally, the clamping wire centering device further includes a cover plate 15, which is disposed on the first mounting seat 11 and at least shields a portion of the structure of the slider. The provision of the cover plate 15 can shield and protect the first driving mechanism 14 and at least a portion of the structure of the slider, and makes the appearance more beautiful.

[0069] Optionally, the clamping wire centering device further comprises a cover 16, the cover 16 is connected to the cover plate 15, and the first clamping jaw assembly 13 is slidably arranged in the cover 16 along the first direction. The setting of the cover 16 can cover the movement of the first clamping jaw assembly 13 to prevent the hand from being pinched. Figure 4 As shown, the cover 16 is a frame structure, which can protect the two groups of first clamping jaw assemblies 13. The frame structure is simple in structure and saves materials.

[0070] Optionally, the clamping centering tool further includes a position adjustment mechanism (not shown in the figure), and the first mounting seat 11 is mounted on the position adjustment mechanism, and the position of the first mounting seat 11 and the structure thereon can be adjusted in the vertical direction, the first direction and / or the second direction through the position adjustment mechanism, so as to enable the first clamping jaw assembly 13 to clamp the wire harness at different positions. The specific position adjustment mechanism is not specifically limited here, as long as the position adjustment of the first mounting seat 11 and the structure thereon in the vertical direction, the first direction and / or the second direction can be achieved.

[0071] Because the traditional wire clamping tool is large in size and its installation position is far from the welding point, the front end of the wire harness is bent. The wire clamping centering device has a compact structure and small size, which is easy to install in a small space. The structure can be installed near the welding point, so that the distance between the tool and the welding point is small, thereby solving the problem of wire harness bending.

[0072] Embodiment 2:

[0073] In order to solve the above problems, this embodiment provides a wire clamping and centering device, which includes a driving mechanism, the output end of the driving mechanism is connected to at least two groups of clamping components, and a clamping space for the wire harness is formed between each group of clamping components. The driving mechanism can drive at least two groups of clamping components to move closer or farther together to reduce or expand the clamping space. The wire harness is placed in the clamping space, and when each group of clamping components moves closer to each other, the size of the clamping space is reduced, so that the wire harness is clamped in the center, avoiding the eccentricity of the welding area caused by the inconsistency between the center of the wire harness and the center of the terminal, thereby improving the welding quality.

[0074] Specifically, Figure 5-Figure 9 As shown, this embodiment provides a wire clamping and centering device, including three groups of clamping assemblies, two of which are second clamping jaw assemblies 23, and the other group of clamping assemblies is a supporting seat 24, the driving mechanism is a second driving mechanism 21, the output end of the second driving mechanism 21 is connected to the two groups of second clamping jaw assemblies 23, the second driving mechanism 21 is used to drive the two groups of second clamping jaw assemblies 23 to move closer to or away from each other along a first direction; the supporting seat 24 is movably installed on the two groups of second clamping jaw assemblies 23 and is located between the two groups of second clamping jaw assemblies 23, the supporting seat 24 is used to support the wiring harness 100, and the two groups of second clamping jaw assemblies 23 move closer to or away from each other to drive the supporting seat 24 to rise and fall.

[0075] The wire clamping and centering device drives the two groups of second jaw assemblies 23 to move closer to or away from each other along a first direction through the second driving mechanism 21. When the two groups of second jaw assemblies 23 move closer to or away from each other, the supporting seat 24 can be driven to rise and fall. The supporting seat 24 can support the wire harness 100 when clamping the wire harness 100. The two groups of second jaw assemblies 23 cooperate with the supporting seat 24 to clamp the wire harness 100 in the center so that the center of the wire harness is consistent with the center of the terminal. Moreover, the wire clamping and centering device in this embodiment can keep the central axis of the wire harness on the same reference when clamping wire harnesses of different thicknesses.

[0076] In this embodiment, the second drive mechanism 21 is a thumb cylinder, which has the following advantages: 1. Small size: The thumb cylinder has a compact structure and small size, which can adapt to the needs of narrow spaces. 2. Fast response: The thumb cylinder has a fast response speed, is easy to operate, and is convenient to debug, which can greatly improve work efficiency. 3. High accuracy: The thumb cylinder has high precision, low friction, and accurate and stable output torque, and can be used in high-precision work fields. 4. High reliability: The thumb cylinder has a simple structure, few parts, stable and reliable operation, and is easy to maintain and maintain. In other embodiments, the structure of the second drive mechanism 21 is not limited to the above-mentioned thumb cylinder, but can also be other drive structures, as long as it can achieve the synchronous driving of the two groups of second jaw assemblies 23 to move closer or farther from each other.

[0077] Specifically, the second clamping jaw assembly 23 includes two groups of clamping jaws arranged at intervals, which are second clamping jaws 231. A connecting shaft 232 is arranged between the two groups of second clamping jaws 231 of the same group of second clamping jaw assemblies 23. The two groups of second clamping jaws 231 are installed on the connecting block 22, and the connecting block 22 is installed on the output end of the second driving mechanism 21; a symmetrical second inclined guide rail 240 is arranged on the supporting seat 24. In this embodiment, the second inclined guide rail 240 is a through hole that passes through the supporting seat 24 along the second direction, and the second inclined guide rail 240 forms an angle with the vertical direction. The connecting shafts 232 of the two groups of second clamping jaw assemblies 23 are respectively penetrated in a group of second inclined guide rails 240, and the connecting shafts 232 can move along the corresponding second inclined guide rails 240. Through the cooperation between the second inclined guide track 240 on the supporting seat 24 and the connecting shaft 232 of the second clamping jaw assembly 23, the two groups of second clamping jaw assemblies 23 can move in the second inclined guide track 240 through the connecting shaft 232 when moving closer to or away from each other, and synchronously drive the supporting seat 24 to rise and fall. The structural design of the supporting seat 24 is relatively ingenious. When the second clamping jaw assembly 23 clamps the wiring harness 100, the supporting seat 24 can move upward and support the wiring harness 100, thereby cooperating with the second clamping jaw assembly 23 to achieve the center clamping of the wiring harness 100.

[0078] Furthermore, if Fig. 9As shown, the second clamping jaw 231 includes a clamping jaw body 2311 and at least two clips 2312 arranged inside the clamping jaw body 2311, and the clips 2312 are gradually inclined from top to bottom toward the direction close to the clamping jaw body 2311, so that when the two groups of second clamping jaws 231 and the supporting seat 24 are close to each other, the position of the wire harness 100 is adjusted, thereby centered positioning and clamping the wire harness 100. Each clip 2312 is arranged on the clamping jaw body 2311 at intervals along the second direction, and the clips 2312 of the two groups of second clamping jaws 231 arranged oppositely are staggered, so that when the two groups of second clamping jaws 231 clamp the wire harness 100, they can extend between the clips 2312 of the opposite group of second clamping jaws 231, thereby achieving tight clamping of the wire harness 100.

[0079] In this embodiment, two clips 2312 are arranged at intervals on one of the two second clips 231 arranged opposite to each other, and three clips 2312 are arranged at intervals on the other second clip 231, and the spacing between two adjacent clips 2312 is equal to the thickness of the clips 2312. In other embodiments, the number of groups of clips 2312 is not limited to the above number, and the number of groups of clips 2312 can be adjusted according to needs.

[0083] Optionally, the mounting plate 26 is movably arranged on the second mounting seat 25, and a height adjustment member 29 is arranged between the mounting plate 26 and the second mounting seat 25, and the height adjustment member 29 is used to adjust the height of the mounting plate 26. The height of the mounting plate 26 can be adjusted by the height adjustment member 29, so that the height of the mounting plate 26 and the structure mounted thereon can be adjusted, thereby meeting the requirements for clamping the wire harness 100 of different heights, and expanding the application scope of the wire clamping and centering device.

[0084] In this embodiment, the second mounting seat 25 includes a second mounting seat body 251 and a guide plate 252 vertically connected to the second mounting seat body 251.

The fixed seat connected to the mounting plate 26 is located in the guide groove 2521 and can move along the extension direction of the guide groove 2521. In this embodiment, the height adjustment member 29 is a bolt, which passes through the fixed seat on the mounting plate 26 and can rotate relative to the fixed seat, but the bolt does not move relative to the fixed seat in its axial direction. The height adjustment member 29 is threadedly connected to the second mounting seat 25. By screwing the bolt, the height of the bolt extending into the second mounting seat body 251 is adjusted, thereby changing the height of the mounting plate 26. The height adjustment member 29 has a simple structure and is easy to adjust. In other embodiments, the height adjustment member 29 is not limited to a bolt, and can also be other structures, such as a driving cylinder, etc., as long as the height of the mounting plate 26 can be adjusted.

[0085] Furthermore, the guide plate 252 is provided with a mounting hole 2522 extending in the vertical direction, and the mounting plate 26 can be fixedly mounted on the guide plate 252 by passing the fixing member through the mounting plate 26 and the mounting hole 2522, and the fixing member can be adjusted in the mounting hole 2522 when the fixing member is loosened to adjust the height of the mounting plate 26. When the height of the mounting plate 26 is adjusted to the right position, the fixing member is used to lock the mounting plate 26 and the guide plate 252. The second driving mechanism 21 is mounted on the mounting plate 26, and the height position of the connecting plate 262 is adjusted to drive the change of the height position of the second driving mechanism 21.

[0086] Optionally, the clamping wire centering device also includes a guide base 20, on which a guide rail 201 is provided, and a second mounting seat 25 is slidably provided on the guide rail 201 of the guide base 20 along the second direction. The provision of the guide base 20 enables the second mounting seat 25 to move along the second direction, so as to adjust the position of the second mounting seat 25 and the structure thereon, and avoid interference with other structures. In this embodiment, two groups of guide rails 201 are spaced apart along the first direction on the guide base 20, and the second mounting seat 25 is slidably provided on the two groups of guide rails 201 along the second direction, so that the movement of the second mounting seat 25 can be more stable. In other embodiments, the guide rails 201 on the guide base 20 are not limited to being provided in two groups, and three, four or more groups may also be provided, as long as the stable operation of the second mounting seat 25 can be achieved.

[0087] Because the traditional wire clamping tool is large in size and its installation position is far from the welding point, the front end of the wire harness is bent. The wire clamping centering device has a compact structure and small size, which is easy to install in a small space. The structure can be installed near the welding point, so that the distance between the tool and the welding point is small, thereby solving the problem of wire harness bending.
