Description

Technical Field

[0001] This application relates to the field of clamping mechanism technology, and in particular to a clamping mechanism and wire harness processing equipment. Background Technology

[0002] In wire harness processing equipment, the wire harness usually needs to be clamped and then rotated. If the rotation angle is greater than 180 degrees, the air pipes on the pneumatic gripper cylinder will become tangled due to the excessive rotation angle, which may cause the air pipe joints to leak. The air pipe joints will also have their lifespan affected due to excessive stress. Utility Model Content

[0003] This application provides a clamping mechanism and wire harness processing equipment to at least partially solve the technical problem that excessive rotation causes air pipes to become tangled, which may lead to air pipe joint leakage.

[0007] According to a second aspect of this application, this application provides a wire harness processing device, including the clamping mechanism described above.

[0008] This application provides a clamping mechanism, including a rotating assembly and a clamping assembly. The rotating assembly includes a shaft with an air passage, and the rotating assembly is axially rotatable. The clamping assembly includes a drive unit connected to the shaft, and the air passage supplies air to the drive unit. Integrating an external air pipe into the shaft avoids the problems of entanglement and air leakage that can occur with external air pipes when the rotation degree is too large. The air passage runs through the inside of the shaft and supplies air to the drive unit. The drive unit is connected to the shaft to realize the rotation of the material, and the drive unit is used to control the clamping of the material.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0021] The applicant noted that clamping and then rotating the wire harness is a very common process in wire harness processing equipment. For example, if the terminal orientation differs from the actual requirement by 180 degrees after crimping the terminal by a connector machine, the terminal needs to be rotated 180 degrees. The common practice is to use a pneumatic gripper cylinder to clamp the wire harness, and then a motor drives the gripper to rotate 180 degrees. In special cases, a 90-degree rotation is acceptable, but if a 270-degree rotation or any other rotation greater than 180 degrees is required, the air hoses on the pneumatic gripper cylinder become tangled due to excessive rotation. This is unsightly, can cause air leaks at the hose joints, and reduces the lifespan of the hose joints due to excessive stress.

[0022] In view of this, this application provides a clamping mechanism, including a rotating component 1 and a clamping component 2. The rotating component 1 includes a shaft 10 with an air passage 11, and the rotating component 1 is axially rotatable. The clamping component 2 includes a drive unit 20 connected to the shaft 10, and the air passage 11 supplies air to the drive unit 20. Integrating an external air pipe into the shaft 10 avoids the problems of entanglement and air leakage that can occur when the external air pipe rotates too much. The air passage 11 penetrates the interior of the shaft 10 and supplies air to the drive unit 20. The drive unit 20 is connected to the shaft 10 to realize the rotation of the material, and the drive unit 20 is used to control the clamping of the material. This configuration, on the one hand, allows the material to rotate at any degree, improving flexibility and meeting the needs of complex working conditions; on the other hand, it avoids air leakage at the joint of the air passage 11, improving the overall airtightness.

[0023] The clamping mechanism and wire harness processing equipment of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0024] Figure 1 This is a schematic diagram of the clamping mechanism provided in an exemplary embodiment of this application; Figure 2 This is a schematic diagram of the clamping mechanism provided in another exemplary embodiment of this application; Figure 3 This is a cross-sectional view of the clamping mechanism provided in an exemplary embodiment of this application; Figure 4 This is a schematic diagram of the structure of the shaft provided in an exemplary embodiment of this application; Figure 5 This is a cross-sectional view of the rotary shaft provided in an exemplary embodiment of this application.

[0025] Reference Figure 2 and Figure 3This application provides a clamping mechanism, including a rotating assembly 1 and a clamping assembly 2. The rotating assembly 1 includes a shaft 10 with an air passage 11, and the rotating assembly 1 is axially rotatable. The clamping assembly 2 includes a drive unit 20 connected to the shaft 10, and the air passage 11 supplies air to the drive unit 20. Integrating an external air pipe into the shaft 10 avoids the problems of entanglement and air leakage that can occur when the external air pipe rotates too much. The air passage 11 penetrates the interior of the shaft 10 and supplies air to the drive unit 20. The drive unit 20 is connected to the shaft 10 to realize the rotation of the material, and the drive unit 20 is used to control the clamping of the material. With this configuration, on the one hand, the material can achieve rotation of any degree, improving flexibility and meeting the needs of complex working conditions; on the other hand, it can avoid air leakage at the joint of the air passage 11, improving the overall airtightness.

[0026] In some embodiments, refer to Figure 1 The clamping assembly 2 includes a clamping part 21 connected to a drive part 20. The drive part 20 is used to drive the clamping part 21 to clamp materials when air is supplied to the air passage 11. The clamping part 21 is a mechanism that uses pneumatic control to grip various workpieces and products. The drive part 20 can be a single-acting finger cylinder, which generates a clamping force when air is supplied to drive the clamping part 21 to clamp materials. When air is cut off from the single-acting finger cylinder, the clamping part 21 opens to release materials.

[0027] In some embodiments, refer to Figure 1 The clamping part 21 includes two opposing jaws 210; the driving part 20 is used to drive the two jaws 210 to move towards each other or away from each other along the same straight line, thereby realizing the parallel opening and closing motion of the jaws 210. With this configuration, the movement trajectory of the jaws 210 is precisely parallel, the clamping center position is constant, and deformation caused by stress concentration can be avoided.

[0028] In some embodiments, refer to Figure 2 The drive unit 20 includes a cylinder piston (not shown) and an elastic element (not shown). When the air passage 11 of the rotating assembly 1 supplies air to the cylinder, the compressed gas pushes the piston to move axially; when the air supply is cut off, the built-in elastic element drives the piston to retract in the opposite direction. The reciprocating motion of the cylinder piston is converted into the synchronous opening and closing action of the grippers 210 through a mechanical transmission mechanism. Exemplarily, a crank is hinged to the end of the piston rod, and the crank is connected to the two grippers 210 on both sides through a connecting rod. When the piston advances, the crank drives the connecting rod to move the two grippers 210 towards each other and close; when the piston retracts, the connecting rod pulls the grippers 210 to separate in opposite directions. Alternatively, an inclined guide groove is provided on the back of the grippers 210, and a roller at the end of the piston rod is embedded in the groove. When the piston moves linearly, the roller slides along the inclined groove, forcing the grippers 210 to translate in the vertical direction to achieve opening and closing. Alternatively, a rack is integrated into the piston rod, and symmetrical gears are installed at the roots of the two grippers 210. The rack motion drives the gear to rotate in the opposite direction, causing the two grippers 210 to open and close synchronously at the same speed and distance.

[0029] In some embodiments, refer to Figure 1 and Figure 2 The clamping mechanism includes a drive assembly 6, which comprises a motor 60, a driving wheel 61, and a driven wheel 62. The driving wheel 61 is connected to the motor 60, and the driven wheel 62 is sleeved on the shaft 10. The driving wheel 61 and the driven wheel 62 are connected by a transmission belt 63. The clamping mechanism includes a base 7, to which the motor 60 is fixed. It is understood that the driven wheel 62 is keyed to the rotating shaft 102, and the driving wheel 61 is keyed to the output shaft of the motor 60. The driven wheel 62 and the driving wheel 61 are driven by a conveyor belt. The motor 60 can be a servo motor, which can achieve arbitrary angle positioning.

[0030] In some embodiments, refer to Figure 4 The clamping mechanism includes an air outlet pipe 3 and an air inlet pipe 4. The air outlet pipe 3 connects the shaft 10 and the drive unit 20, and the air inlet pipe 4 is connected to the side of the shaft 10 away from the drive unit 20. The overall structure is compact, simple and beautiful, and easy to insert and remove quickly, improving the convenience of maintenance.

[0031] In some embodiments, refer to Figure 3 and Figure 4 The shaft 10 includes a rotary joint 100 and a rotating shaft 102. The rotary joint 100 has a first air passage 101; the rotating shaft 102 has a second air passage 103 communicating with the first air passage 101. At least a portion of the rotating shaft 102 is sleeved on the rotary joint 100 and fixedly connected to the rotary joint 100. Exemplarily, the rotating shaft 102 and the rotary joint 100 are fixedly connected by threads or keyways. The rotating shaft 102 is fixedly connected to the drive unit 20, and the second air passage 103 communicates with the drive unit 20. With this configuration, the rotating shaft 102 can drive the drive unit 20 to rotate when it rotates. The first air passage 101 and the second air passage 103 pass through the interior of the shaft 10 and supply air to the drive unit 20. The rotary joint 100 serves as an air path conversion hub, and the air inlet end of the rotary joint 100 is connected by a dynamic sealing connection to prevent gas leakage from the air inlet pipe 4. When the rotary shaft 102 drives the drive unit 20 to rotate, at least a portion of the rotary joint 100 is fixedly connected to the rotary shaft 102. The rotary shaft 102 drives the rotary joint 100 to rotate, so as to achieve rotation of any degree. At least a portion of the rotary joint 100 is fixedly connected to the air inlet pipe 4, which can prevent the air inlet pipe 4 from getting tangled. On the one hand, the material can achieve rotation of any degree, improving flexibility and meeting the needs of complex working conditions. On the other hand, it can prevent air leakage at the joint of the air passage 11 and improve the overall airtightness.

[0032] In some embodiments, refer to Figure 5The second air passage 103 has a first branch 1030 and a second branch 1031. The first branch 1030 is connected to both the first air passage 101 and the second branch 1031. The first branch 1030 extends axially along the shaft 10, and the second branch 1031 extends radially along the shaft 10. The first air passage 101 extends axially along the shaft 10 and connects to one end of the first branch 1030. The other end of the first branch 1030 connects to the inlet side of the second branch 1031. The outlet side of the second branch 1031 extends radially along the shaft 10 and leads to the outer wall of the rotating shaft 102. This configuration fully utilizes the internal space of the shaft 10 and avoids interference with rotation from external pipes. On the one hand, materials can rotate at any degree, improving flexibility and meeting the needs of complex working conditions. On the other hand, it can prevent air leakage at the joint of the air passage 11, improving overall airtightness.

[0033] In some embodiments, refer to Figure 4 and Figure 5 The clamping mechanism includes an air outlet pipe 3, which is connected to the second branch 1031 and the drive unit 20. The air outlet pipe 3 connects the outlet of the second branch 1031 to the air inlet of the drive unit 20. The air outlet pipe 3 rotates with the rotating shaft 102 and the drive unit 20, eliminating torsional stress and significantly reducing the probability of air leakage. For example, the length of the air outlet pipe 3 is approximately 30mm; this short pipe layout makes the clamping mechanism more compact and allows for quick insertion and removal of the air outlet pipe 3, facilitating maintenance.

[0034] In some embodiments, refer to Figure 3 The clamping mechanism includes an air inlet pipe 4, which is connected to the first air passage 101. Specifically, the air inlet pipe 4 includes an air inlet pipe body (not shown) and an air inlet pipe connector (not shown). One end of the air inlet pipe connector is connected to the rotary joint 100, and the other end of the air inlet pipe connector is connected to the air inlet pipe body. The air inlet pipe body is connected to an external air pump (not shown) away from the air inlet pipe connector. The air pump is used to supply air to the drive unit 20 through the air inlet pipe 4, the first air passage 101, and the second air passage 103.

[0035] In some embodiments, refer to Figure 1 The clamping mechanism includes a fixed plate 5, an air inlet pipe 4 passing through the fixed plate 5 and fixedly connected to the fixed plate 5, and at least a portion of the air inlet pipe 4 being rotatably connected to the rotary joint 100. The fixed plate 5 is fixed to the base 7, and the air inlet pipe 4 includes an air inlet pipe body and an air inlet pipe connector. The air inlet pipe connector passes through the fixed plate 5 and is fixedly connected to the fixed plate 5, thereby preventing the air inlet pipe 4 from getting tangled. On the one hand, the material can achieve rotation at any degree, improving flexibility and meeting the needs of complex working conditions. On the other hand, it can prevent air leakage at the air passage 11 joint, improving the overall airtightness.

[0036] In some embodiments, refer to Figure 4The rotary joint 100 includes a fixed portion 1000, a movable portion 1001, and a sealing portion (not shown). At least a portion of the fixed portion 1000 passes through the movable portion 1001, and the fixed portion 1000 is fixedly connected to the air intake pipe connector. At least a portion of the movable portion 1001 passes through the rotating shaft 102 and communicates with the first air passage 101 and the second air passage 103. The movable portion 1001 is rotatable relative to the fixed portion 1000. The sealing portion is sandwiched between the fixed portion 1000 and the movable portion 1001, thereby ensuring the airtightness of the rotary joint 100.
