Description

Technical Field

[0001] The invention relates to the field of wire harness production equipment, in particular to a positioning tool for screw driving equipment. Background Art

[0002] In the production of automotive electrical products such as wiring harnesses, wiring terminals are usually provided at the end of the wiring harness. The wiring terminals are eventually tightened from above by screws to press them down. While forming a pathway for the wiring harness, the wiring harness is fixed to prevent it from becoming detached when the car is driving. During the installation of the wiring harness terminals, multiple wiring harnesses are tightened by screws at the same time, and the tightening directions of the screws are all the same. As a result, the tightened wiring harness terminals will all deviate and rotate in the tightening direction of the screws. After the screwing process is completed, the wiring harness is twisted in the same direction due to the rotation of the wiring terminals. At this time, in order to facilitate processing at subsequent workstations, the wiring harness is usually pulled outward multiple times to return the wiring terminals to their original position. Since there is no standard execution process for this process, the wiring terminals may not be tightly connected, affecting the pass rate of the wiring terminal screwing process.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1 to 5 The present invention provides a technical solution: a positioning tool for screw driving equipment, comprising an equipment base 1, characterized in that: a fixing plate 3 is installed on the equipment base 1 through a support rod 2, a tooling plate 4 is provided above the fixing plate 3, a transmission assembly 5 is provided in the equipment base 1, the top of the transmission assembly 5 is connected to the bottom of the tooling plate 4, a positioning assembly 6 is provided on the tooling plate 4, the tooling plate 4 and the positioning assembly 6 are used to position the workpiece, a clamping assembly 7 is provided on the outside of the tooling plate 4, the clamping assembly 7 is used to fix the workpiece, a tooling plate positioning rod 8 and a tooling plate limiting rod 9 are further provided on the tooling plate 4, the tooling plate positioning rod 8 is used to position the tooling plate 4, the tooling plate limiting rod 9 is used to limit the movement of the tooling plate 4, and slots 10 are also provided on both sides of the tooling plate 4, and the slots 10 are used to clamp the wiring harness.

[0031] In this embodiment, the tooling plate 4 is divided into two layers, plate 1 41 and plate 2 42, which are fixedly connected together. Plate 1 41 is provided with a weight-reducing hole, and plate 2 42 is provided with a limiting hole 43. The limiting hole 43 cooperates with the top plate 83 to lock the position of the tooling plate 4 so that the tooling plate 4 will not move, ensuring that the workpiece will not move when screwing. The tooling plate 4 is also provided with an avoidance hole whose width is greater than the tooling plate positioning rod 8 to facilitate the rotation of the tooling plate 4.

[0032] In this embodiment, the transmission assembly 5 includes a lifting motor 51, a lifting screw 52 and a connecting flange 53. The lifting motor 51 is installed on the equipment base 1. The lifting screw 52 is connected to the output end of the lifting motor 51 and can be driven by the lifting motor 51 to rotate freely. The connecting flange 53 is connected to the top of the lifting screw 52 through a damping ring 54. The connecting flange 53 is installed under the tooling plate 4. The lifting screw 52 is driven to rotate by the lifting motor 51, which can rotate the connecting flange 53. When rotating, the tooling plate 4 will also be driven to rotate through the connecting flange 53, so that the terminal of the tightened wiring harness is rotated, thereby relieving the force on the wiring harness.

[0033] In this embodiment, the positioning assembly 6 includes a positioning block 1 61 and a positioning block 2 62. The positioning block 1 61 and the positioning block 2 62 each include two symmetrically arranged parts. The positioning block 1 61 and the positioning block 2 62 are respectively installed on the corners of the tooling plate 4. The workpiece is placed between the positioning block 1 61 and the positioning block 2 62 for positioning. The positioning block 1 61 and the positioning block 2 62 have different shapes, which can prevent the workpiece from being placed upside down.

[0034] In this embodiment, the clamping assembly 7 includes a fixed base 71, a cylinder 72, and a clamping block 73. The bottom of the fixed base 71 is fixed to the fixed plate 3 by bolts, the cylinder 72 is installed on the top of the fixed base 71, and the bottom of the clamping block 73 is connected to the output shaft of the cylinder 72. A rubber pad 74 is provided on the working surface of the clamping block 73. A motion gap 44 is provided at a position corresponding to the fixed base 71 on the tooling plate 4. The motion gap 44 is used to ensure that the tooling plate 4 will not be blocked by the fixed base 71 when it rotates. The clamping block 73 driven by the cylinder 72 can fix the workpiece by pressing down after the workpiece is placed in the tooling plate 4.

[0035] In this embodiment, the tooling plate positioning rod 8 is provided with two symmetrical groups, each group includes a bottom mounting rod 81, an adjusting nut 82 and a top plate 83. The bottom mounting rod 81 is fixed on the fixed plate 3, and a top plate 83 is connected to the top of the bottom mounting rod 81 by a bolt. The adjusting nut 82 is threadedly connected to the bolt. When the top plate 83 is located in the tooling plate 4, the tooling plate 4 will be fixed so that the tooling plate 4 will not rotate. After the tooling plate 4 is driven by the transmission assembly 7 to drop to the top plate 83 and disengage from the limiting hole 43, the tooling plate 4 can rotate freely.

[0036] In this embodiment, the tooling plate limit rod 9 includes a rod body 91 and a touch switch 92. The rod body 91 is fixed on the fixed plate 3, and the touch switch 92 is installed on the side of the rod body 91. The touch switch 92 is electrically connected to the transmission assembly 5. The tooling plate limit rod 9 includes two groups and is respectively arranged on both sides of the tooling plate 4. The touch switch 92 is used to control the lifting motor 51.

[0037] A positioning tool for screw driving equipment, wherein a spring lock 101 for sealing the slot 10 is provided on the outside of the slot 10, and the wiring harness placed in the slot 10 will be locked in the slot 10 by the spring lock 101 to fix the wiring harness.

[0038] Working principle: When in use, first install the workpiece on the tooling plate 4, fix it through the positioning block 1 61 and the positioning block 2 62, and the wiring harness for installation will be placed in the slot 10 and then fixed by the spring lock 101. At the same time, the control cylinder 72 drives the clamping block 73 to fix the workpiece on the tooling plate 4, and then all the screws at the wiring terminals of the wiring harness are installed. After all the screws are installed, turn on the lifting motor 51 through the external switch, and the lifting motor 51 rotates, driving the lifting screw 52 to rotate. Initially, since the top plate 83 of the tooling plate 4 is stuck, the tooling plate 4 cannot rotate. The rotation of the lifting screw 52 will drive the damping ring 54 to rotate in the connecting flange 53, and at the same time, the lifting screw 52 drives the tooling plate 4 to descend until the top plate 83 is stuck. When the plate 83 comes out of the limit hole 43, the damping ring 54 will drive the tooling plate 4 to rotate through the rotation of the lifting screw 52. The rotation direction of the tooling plate 4 is opposite to the tightening direction of the screw, so that the tightened terminal can be rotated, and the force in one direction on the wiring harness can be removed, which is convenient for the subsequent assembly process. Then, when the tooling plate 4 rotates to the tooling plate limit rod 9, the touch switch 92 here will be started, controlling the lifting motor 51 to reverse, so that the tooling plate 4 reverses and rises, rises to the top plate 83 and re-enters the limit hole 43. At this time, when it touches the touch switch 92 of another tooling plate limit rod 9, this touch switch 92 controls the lifting motor 51 to turn off, and the entire tooling plate 4 is reset. At this time, the workpiece is removed and the next screwing operation is carried out.

[0039] Based on the above, the invention can reliably position, clamp and fix the placed workpiece through the set tooling plate, positioning assembly and clamping assembly, and the workpiece will not move when screwing, affecting the installation of the screws; the transmission assembly in the invention can drive the tooling plate and the workpiece to rotate in the opposite direction of tightening the screws after the screwing is completed, so that the wiring terminal can partially return to its position, reducing the force on the wiring harness and facilitating the subsequent installation of the wiring harness.

[0040] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
