Description

Technical Field

[0001] The utility model relates to the field of flat wire motor stator processing, and particularly relates to a wire clamping mechanism. Background Art

[0002] A wire clamping mechanism is a supporting device for processing flat wire motor stators and is used in flat wire motor stator production equipment. This tooling only uses one cylinder to support the product and simultaneously center-clamp the two sides of the copper wire. It is actually applied to the copper wire peeling and clamping station. With the continuous development of technology, people's requirements for the manufacturing process of wire clamping mechanisms are also getting higher and higher.

[0003] The existing wire clamping mechanism has certain drawbacks when in use. First, when processing copper wires, since there will be a lateral force during copper wire peeling, the copper wire may be deformed or unqualified in size, which is not conducive to people's use. Also, the existing wire clamping mechanism is relatively large in size and occupies a large space, bringing certain adverse effects to the actual use process. Therefore, we propose a wire clamping mechanism. Summary of the Utility Model

[0004] Technical problems to be solved: Aiming at the deficiencies of the prior art, the utility model provides a wire clamping mechanism. Only one cylinder is used to support the product and simultaneously center-clamp the two sides of the copper wire. It is actually applied to the copper wire peeling and clamping station. Since there will be a lateral force during copper wire peeling, however, this tooling clamps the sides, ensuring that the position of the copper wire is fixed and reliable during peeling, thus avoiding the phenomenon of copper wire deformation or unqualified size. In addition, this mechanism only uses one cylinder to push once to complete the support and clamping of the workpiece, saving one step compared with conventional support and clamping, improving the cycle efficiency. At the same time, the clamping part of this clamping tooling is relatively small and can be applied to narrow spaces, effectively solving the problems in the background art.

[0005] Technical solution: To achieve the above purpose, the technical solution adopted by the utility model is as follows: A wire clamping mechanism includes a fixing plate. A clamp is positioned in the middle of the upper end of the fixing plate. Fixed bases are installed on both sides of the upper end of the fixing plate and on both sides of the clamp. A left support and clamping tooling and a right support and clamping tooling are respectively installed on the upper ends of the fixed bases on both sides of the clamp. A left support and clamping cylinder and a right support and clamping cylinder are installed at the bottom of the fixing plate. A left adjusting rod is connected between the left support and clamping cylinder and the left support and clamping tooling. A right adjusting rod is connected between the right support and clamping cylinder and the right support and clamping tooling. A copper wire is positioned in the middle of the clamp.

[0006] Preferably, the left support clamping tooling includes a support member, a jaw, a second jaw connecting member, a second fixed seat, a rotating shaft, a movable rod, a cam follower, a first fixed seat and a first jaw connecting member. The first fixed seat and the second fixed seat are respectively located on both sides of the bottom. A first jaw connecting member is connected between the first fixed seat and the jaw. A second jaw connecting member is connected between the second fixed seat and the jaw. A rotating shaft is connected between the movable rod and the first jaw connecting member and the second jaw connecting member. A cam follower is arranged between the first fixed seat and the first jaw connecting member. The support member is located at the top of the movable rod, and the movable rod is located between the jaws. The copper wire passes through the left support clamping tooling and the right support clamping tooling. The left support clamping cylinder and the right support clamping cylinder move upward, driving the movable rods on both sides to move upward. The support member finally contacts the workpiece to play a supporting role. At the same time, the first jaw connecting member and the second jaw connecting member on the movable rod will rotate around the rotating shaft to clamp the workpiece.

[0007] Preferably, the fixed base and the clamp are fixed to the upper end of the fixed plate by bolts, and the left support clamping cylinder and the right support clamping cylinder are fixed to the bottom of the fixed plate by bolts.

[0008] Preferably, the left support clamping cylinder drives the left adjusting rod and drives the left support clamping tooling to adjust. The right support clamping cylinder drives the right adjusting rod and drives the right support clamping tooling to adjust.

[0009] Preferably, the first fixed seat and the second fixed seat are fixed by bolts, and the first fixed seat and the first jaw connecting member are movable through a cam follower.

[0010] Preferably, the movable rod drives the first jaw connecting member and the second jaw connecting member to adjust their activities through the rotating shaft, and the second jaw connecting member and the first jaw connecting member adjust the position of the jaw to clamp and position at the support member.

[0011] Advantages: Compared with the prior art, the present utility model provides a wire clamping mechanism with the following advantages: This wire clamping mechanism uses only one cylinder to support the product and simultaneously center and clamp both sides of the copper wire. When actually applied to the copper wire peeling and clamping station, since there will be a lateral force when the copper wire is peeled, this tooling clamps the sides to ensure that the position of the copper wire is fixed and reliable during peeling, thus avoiding the phenomenon of copper wire deformation or unqualified dimensions. In addition, this mechanism only uses one cylinder to push once to complete the support and clamping of the workpiece, saving one step compared with conventional support clamping, improving the cycle efficiency. At the same time, the clamping part of this clamping tooling is relatively small and can be applied in a narrow space. This mechanism mainly consists of a fixing plate, a fixed seat, a movable rod, a support member, a jaw connecting seat, a cam follower, a rotating shaft, and a cylinder. Among them, the rotating shafts on the movable rod fix the left jaw connecting member and the left jaw connecting member to the movable rod. A cam follower is installed in the fixed seat to enable the jaw connecting member to perform a rotating clamping action when the movable rod moves. Since the two jaws are concentrically connected by the same rotating shaft, the workpiece can be centered and positioned when clamping the workpiece. A jaw is installed on the jaw connecting member to facilitate the replacement of worn jaws. A support member is installed on the movable member, and when the movable rod moves upward, this support member can support the lower surface of the product. The working process of the tooling is that the copper wire initially passes through the support and clamping tooling horizontally. The support and clamping cylinder moves upward, driving the movable rod to move upward. The support member finally contacts the workpiece to perform a supporting function. At the same time, the jaw connecting member on the movable rod will rotate around the rotating shaft to clamp the workpiece. The entire wire clamping mechanism has a simple structure, is easy to operate, and has a better use effect compared with the traditional method. Brief Description of the Drawings

[0021] As Figures 1-5As shown in the figure, a wire clamping mechanism includes a fixing plate 1. In the middle of the upper end of the fixing plate 1, a clamp 5 is positioned. On both sides of the clamp 5 at the upper end of the fixing plate 1, fixed bases 7 are installed. On both sides of the clamp 5 at the upper end of the fixed bases 7, a left support clamping tool 4 and a right support clamping tool 6 are respectively installed. At the bottom of the fixing plate 1, a left support clamping cylinder 10 and a right support clamping cylinder 9 are installed. A left adjusting rod 2 is connected between the left support clamping cylinder 10 and the left support clamping tool 4, and a right adjusting rod 8 is connected between the right support clamping cylinder 9 and the right support clamping tool 6. In the middle of the clamp 5, a copper wire 3 is positioned. Only one cylinder is used to support the product and at the same time centering and clamping the two side surfaces of the copper wire. It is actually applied to the copper wire peeling and clamping station. Since there will be a lateral force when the copper wire is peeled, however, this tool clamps the side surface, ensuring that the position of the copper wire is fixed and reliable during peeling. Therefore, the phenomenon of copper wire deformation or unqualified dimensions is avoided. In addition, this mechanism only uses one cylinder to push once to complete the support and clamping of the workpiece, saving one step compared with the conventional support clamping, improving the beat efficiency. At the same time, the clamping part of this clamping tool is relatively small and can be applied to narrow spaces.

[0022] Further, the left support clamping tool 4 includes a support 11, a clamping jaw 12, a second clamping jaw connecting piece 13, a second fixed seat 14, a rotating shaft 15, a movable rod 16, a cam follower 17, a first fixed seat 18 and a first clamping jaw connecting piece 19. The first fixed seat 18 and the second fixed seat 14 are respectively located on both sides of the bottom. A first clamping jaw connecting piece 19 is connected between the first fixed seat 18 and the clamping jaw 12, and a second clamping jaw connecting piece 13 is connected between the second fixed seat 14 and the clamping jaw 12. A rotating shaft 15 is connected between the movable rod 16 and the first clamping jaw connecting piece 19 and the second clamping jaw connecting piece 13. A cam follower 17 is arranged between the first fixed seat 18 and the first clamping jaw connecting piece 19. The support 11 is located at the top of the movable rod 16, and the movable rod 16 is located between the clamping jaws 12. The copper wire 3 passes through the left support clamping tool 4 and the right support clamping tool 6 horizontally. When the left support clamping cylinder 10 and the right support clamping cylinder 9 move upward, the movable rods 16 on both sides are driven to move upward. The support 11 finally contacts the workpiece for support, and at the same time, the first clamping jaw connecting piece 19 and the second clamping jaw connecting piece 13 on the movable rod 16 will rotate around the rotating shaft 15 to clamp the workpiece.

[0023] Further, the fixed bases 7 and the clamp 5 are fixed to the upper end of the fixing plate 1 by bolts, and the left support clamping cylinder 10 and the right support clamping cylinder 9 are fixed to the bottom of the fixing plate 1 by bolts.

[0024] Further, the left support clamping cylinder 10 drives the left adjusting rod 2 and drives the left support clamping tool 4 to adjust, and the right support clamping cylinder 9 drives the right adjusting rod 8 and drives the right support clamping tool 6 to adjust.

[0025] Further, the first fixing base 18 and the second fixing base 14 are fixed by bolts, and the first fixing base 18 and the first jaw connecting member 19 are movable through a cam follower 17.

[0026] Further, the movable rod 16 drives the first jaw connecting member 19 and the second jaw connecting member 13 to adjust and move through the rotating shaft 15, and the second jaw connecting member 13 and the first jaw connecting member 19 adjust the position of the jaws 12 to clamp and position the support member 11.

[0027] Working principle: The utility model includes a fixing plate 1, a left adjusting rod 2, a copper wire 3, a left support clamping tooling 4, a clamp 5, a right support clamping tooling 6, a fixed base 7, a right adjusting rod 8, a right support clamping cylinder 9, a left support clamping cylinder 10, a support member 11, jaws 12, a second jaw connecting member 13, a second fixing base 14, a rotating shaft 15, a movable rod 16, a cam follower 17, a first fixing base 18, and a first jaw connecting member 19. This mechanism mainly consists of a fixing plate, a fixing base, a movable rod, a support member, a jaw connecting seat, a cam follower, a rotating shaft, and a cylinder. Among them, the rotating shaft on the movable rod fixes the left jaw connecting member and the left jaw connecting member on the movable rod. A cam follower is installed in the fixing base to enable the jaw connecting member to perform a rotating clamping action when the movable rod moves. Since the two jaws are concentrically connected by the same rotating shaft, the workpiece can be centered and positioned when clamping the workpiece. Jaws are installed on the jaw connecting member for convenient replacement of worn jaws. A support member is installed on the movable member, and when the movable rod moves upward, the support member can support the lower surface of the product. The working process of the tooling is that the copper wire initially passes through the support clamping tooling horizontally. The support clamping cylinder moves upward, driving the movable rod to move upward. The support member finally contacts the workpiece for support, and at the same time, the jaw connecting member on the movable rod rotates around the rotating shaft to clamp the workpiece. Only one cylinder is used to support the product and clamp the two sides of the copper wire in the center. In actual application to the copper wire peeling and clamping station, since there is a lateral force when peeling the copper wire, this tooling clamps the side to ensure that the position of the copper wire is fixed and reliable during peeling, thus avoiding deformation or unqualified dimensions of the copper wire. In addition, this mechanism only uses one cylinder to push once to complete the support and clamping of the workpiece, saving one step compared with conventional support clamping, improving the beat efficiency. At the same time, the clamping part of this clamping tooling is relatively small and can be applied in a narrow space.
