Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, and in particular to a wire harness connector grinding device. Background Technology

[0002] During the wire harness manufacturing process, after the wire harness connectors are stamped and crimped, burrs and oxide layers will form on their surface. Therefore, grinding equipment is used for processing. During the wire harness grinding process, a fixture is needed to hold the connector before grinding. Furthermore, metal dust and fine grinding shavings are generated during the wire harness grinding process. Therefore, using conventional grinding equipment for connector clamping and grinding has the following drawbacks: Traditional clamping mechanisms typically use motors or cylinders to clamp a single connector, or simultaneously clamp two or more sets. After clamping the wire harness connector, conventional fixtures cannot easily unlock and adjust the clamping components on one side. When loading or unloading, the entire workpiece needs to be released, and the operator needs to wait for the grinding process. The next wire harness connector can only be armored after the grinding is completed. Therefore, the waiting process limits the material changing operation steps, making it difficult to achieve alternating loading and unloading of wire harness connectors. Only one armoring can be done and then waiting for grinding, which seriously reduces the processing efficiency of wire harness connectors. During the grinding process of the joint, a large amount of metal dust and fine grinding shavings are generated. The traditional solution is to set up a separate, independently driven fan for negative pressure collection. However, the dust removal components have the drawbacks of additional energy consumption and installation costs. Summary of the Invention

[0003] This invention relates to a wire harness connector grinding device, which solves the problem that traditional clamps cannot be unlocked independently on one side and can only be loosened and replaced as a whole, as well as the problem that the connector grinding device is equipped with a separate independently driven dust removal component.

[0025] Example 1: Please refer to Figures 1 to 9 : This invention proposes a wire harness connector grinding device, comprising: a worktable 100, a support plate 200 installed on the side of the upper end of the worktable 100, a drive shaft 320 installed inside the support plate 200, the right side of the drive shaft 320 being rotatably connected to the support plate 200; an electric motor 310 fixedly installed on the outer side of the support plate 200, the rotor shaft of which is fixedly connected to the left side of the drive shaft 320; a protective tube fixedly installed on the inner side of the support plate 200, through which the drive shaft 320 passes, the protective tube protecting the drive shaft 320 and enhancing its stress resistance; a flow guide 530 fixedly installed on the right side of the protective tube, with only one flow guide 530, controlling the electric motor 310 to drive the drive shaft 320 to rotate, thereby driving the grinding wheel 400 to rotate for structural grinding; In this embodiment, a grinding wheel 400 is fixedly installed on the right side of the drive shaft 320, and a grinding needle 410 is installed on the right side of the grinding wheel 400. The grinding wheel 400 and the grinding needle 410 are coaxial. A flow-guiding housing 510 is installed at the upper end of the grinding wheel 400, and a protective cover 420 is installed at the bottom of the flow-guiding housing 510. The protective cover 420 covers the upper end of the grinding wheel 400. Specifically, the protective cover 420 blocks high-speed flying grinding chips and debris to prevent injury to operators. A collection housing 520 is installed on the upper inner side of the support plate 200. There is only one collection housing 520, and a filter screen is installed inside it. The filter screen is located at the upper part of the inside of the collection housing 520. Specifically, the collection housing 520 is used to collect metal dust and debris generated by joint grinding. The internal filter screen can intercept solid grinding chips and only allow airflow to pass through, realizing air-slag separation and effectively collecting metal dust and debris. In this embodiment, a turbine blade 540 is mounted on the outer side of the drive shaft 320, controlling the drive shaft 320 to drive the turbine blade 540 to rotate. A keyway is provided inside the drive shaft 320, and the turbine blade 540 is installed on the outer side of the keyway. A shroud 530 covers the turbine blade 540. When the turbine blade 540 rotates, it generates an acute airflow inside the shroud 530. An exhaust port is provided on the left side of the shroud 530, close to the grinding wheel 400. Specifically, it uses negative pressure suction to suck up dust and debris around the grinding wheel 400, eliminating the need for an additional independently driven fan, thus saving on device cost and energy consumption. The right side of the shroud 510 and the left side of the collection shroud 520 are also included. Each is equipped with a connecting pipe. The flow-in housing 510 and the collection housing 520 are respectively connected to the connecting pipe. The connecting pipe of the collection housing 520 is located at the bottom of the filter screen, allowing the dust in the grinding area to flow into the collection housing 520 along the connecting pipe. A negative pressure air pipe is installed at the upper end of the flow-in hood 530 and the right side of the collection housing 520. When the turbine blade 540 rotates, a negative pressure is generated in the negative pressure air pipe, thereby generating a negative pressure airflow in the collection housing 520. Combined with the connecting pipes of the flow-in housing 510 and the collection housing 520, the flow-in housing 510 generates suction on the grinding wheel 400, sucking away the dust and debris generated by the grinding wheel 400 during operation from all directions, effectively improving the grinding environment. In this embodiment, a support column 600 is installed at the middle of the upper end of the workbench 100, and a placement plate 750 is provided at its upper end. A stable housing 610 extending outwards is provided on the left side of the support column 600, and a cylinder 710 is installed through it. A threaded hole is opened inside the stable housing 610, and a matching bolt is installed in the threaded hole to secure the cylinder 710. A positioning plate 720 is installed on the right side of the push rod of the cylinder 710. There is one positioning plate 720, which controls the lateral displacement of the positioning plate 720 caused by the cylinder 710. Two clamping plates 730 are installed at the front and rear positions of the positioning plate 720. A positioning block is provided at the front and rear positions of the positioning plate 720. The positioning block has a T-shaped structure. A sliding groove corresponding to the positioning block is opened on the inner side of the clamping plate 730. The positioning block is engaged in the sliding groove. Specifically, the positioning block and the sliding groove... The positioning plate 720 is equipped with a sliding hole inside, which houses two sliding locking rods 740. A control plate extends outward from the side of each locking rod 740. Applying pressure to the control plate causes the locking rod 740 to retract. A support spring is installed on the outside of the locking rod 740, which pushes the locking rod 740 outward. A locking hole is opened on the side of each pressing plate 730, and the outward extension of the locking rod 740 is inserted into the locking hole. The locking rod 740 locks the position of the pressing plate 730. The pressing plate 730 can be unlocked by moving the locking rod 740 individually, allowing the operator to adjust any pressing plate 730 individually according to processing needs. This facilitates the individual loading and unloading of wire harness connectors and synchronous clamping. In this embodiment, movable plates 780 are installed at both the front and rear positions of the placement plate 750. Sliding grooves, U-shaped in structure, are provided at both the front and rear positions of the placement plate 750, through which the movable plates 780 pass. A positioning rod 770 is fixedly installed at the bottom of the placement plate 750. A sliding hole is provided at the bottom of each movable plate 780, through which the positioning rod 770 passes. A support spring is installed on the outside of the positioning rod 770, elastically supporting the movable plate 780 outwards and automatically adjusting it to the book-dispensing position for easy placement of the connector and automatic unlocking. A clamping plate 790 is installed on the inner side of each movable plate 780, with an adjusting plate fixedly installed on its outer end face. The adjusting plate is rectangular in structure and provides circumferential and vertical positioning for the clamping plate 790. A sliding hole is provided at the upper end of each movable plate 780, corresponding to the adjusting plate, through which the adjusting plate passes. The clamping plate 790, in conjunction with the adjusting plate, allows for flexible adjustment of different types of connectors. A locking bolt is installed at the upper end of the moving plate 780, with its bottom extending into the sliding hole of the moving plate 780. Tightening the locking bolt locks the position of the clamping plate 790, ensuring stable clamping of the wire harness connector by the clamping plate 790. The outer end face of the moving plate 780 contacts the inner end face of the pressure plate 730. When the pressure plate 730 moves, it pushes the two pressure plates 730 to move inward synchronously, thereby causing the two clamping plates 790 to move synchronously and clamp wire harness connectors at different positions simultaneously. A baffle 760 is provided at the middle position of the upper end of the placement plate 750. The baffle 760 is aligned with the clamping plate 790, and its inner end face has a slot with a U-shaped structure. The baffle 760 blocks the end of the wire harness connector and, in conjunction with the clamping plate 790, stably clamps the wire harness connector.

[0026] Example 2, based on Example 1, such as Figures 1-9 As shown, the electric motor 310 and drive shaft 320 cooperate to form a drive mechanism; the drainage housing 510, collection housing 520, drainage cover 530, and turbine blades 540 cooperate to form a cleaning unit; the cylinder 710, positioning plate 720, pressing plate 730, locking rod 740, placement plate 750, baffle 760, positioning rod 770, moving plate 780, and clamping plate 790 cooperate to form a clamping mechanism.

[0027] Example 3, based on Example 1, such as Figures 1-9 As shown, a drive mechanism is installed on the upper end of the worktable 100 to drive the support plate 200, the grinding wheel 400 and the grinding needle 410 to move in different directions, so that the grinding wheel 400 and the grinding needle 410 can effectively grind different positions of the wire harness.

[0028] The working principle of this embodiment: Before grinding the wire harness connector, the operator adjusts the position of the clamping plate 790 according to the specifications of the wire harness connector to be processed. After the position adjustment is completed, the locking bolts are tightened to lock the position of the clamping plate 790. The wire harness connector is placed on the placement plate 750 so that the wire harness connector is between the baffle 760 and the clamping plate 790. The staff started the cylinder 710. The push rod of the cylinder 710 drove the positioning plate 720 to move laterally, pushing the two clamping plates 730 and the moving plate 780 to move inward in sync. The two clamping plates 790 came together to firmly clamp the wire harness connector. The staff then started the electric motor 310, which drove the drive shaft 320, the grinding wheel 400 and the turbine blade 540 to rotate synchronously. The grinding wheel 400 rotated at high speed to grind the burrs and oxide layer on the surface of the wire harness connector. The turbine blades 540 rotate and create negative pressure inside the shroud 530. The negative pressure airflow enters the shroud 510 through the negative pressure air pipe and the connecting pipe. The metal dust and debris generated during grinding are continuously sucked into the pipe and eventually enter the collection shroud 520. The filter screen filters the metal dust and debris, and the grinding debris is stored in the collection shroud 520. The airflow is discharged normally and blown towards the grinding wheel 400 to achieve auxiliary heat dissipation of the grinding wheel 400 and simultaneous dust removal during the grinding process. When it is necessary to grind the internal conductive sheet of the connector, install the grinding needle 410 on the coaxial position on the left side of the grinding wheel 400; start the electric motor 310 according to the above steps, and the grinding needle 410 grinds the internal conductive sheet of the connector. After the joint grinding is completed, the control cylinder 710 is reset, the clamping plate 790 releases the joint, the worker removes the finished product, and the next set of joints can be processed. During the grinding of another connector, the worker can remove and replace the other ground connector. At this time, the worker needs to press the locking lever 740 to unlock the corresponding clamping plate 730, slide the clamping plate 730 to the left to unlock the corresponding clamping plate 790, and then the other ground connector will be unlocked, and the next connector can be replaced.
