Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing, specifically relating to an automated door hinge hole processing equipment. Background Technology

[0002] Car door hinges are primarily used to connect car doors to the car body frame, supporting and controlling the opening and closing movements of the doors. They need to withstand the weight of the door and frequent opening and closing actions, thus requiring higher strength and durability in their design. Compared to ordinary hinges, car door hinges are not thin-plate structures; they are thicker and more rigid, making hole machining on them more challenging. The holes in car door hinges are machined on different surfaces. Current machining methods are semi-automated, with the drilling equipment tapping and chamfering holes on a single surface at a time. Manual handling of parts loading, unloading, and collection is required. Throughout the process, the hinge parts undergo multiple positioning and fixing processes, increasing the likelihood of machining errors and resulting in low efficiency. To support machine production, at least two workers are needed for loading, unloading, and inspection, highlighting the high dependence on manual labor. Therefore, improvements to existing equipment are necessary. Summary of the Invention

[0003] To address the aforementioned problems and technical needs, this utility model provides an automated door hinge hole processing equipment. This equipment can automatically feed, process, and unload all holes on the door hinge without manual intervention, saving manpower, improving processing efficiency, and exhibiting a high degree of intelligence.

[0004] The technical solution of this utility model is as follows: an automated door hinge hole processing equipment, comprising...

[0005] The frame is equipped with a processing table, hole processing equipment and a protective cover assembly. Multiple hole processing equipment are installed sequentially on the processing table. The protective cover assembly surrounds the processing table from the outside and the top to protect the processing area.

[0006] The chain plate rotation mechanism is set on the processing table and the area below the table, and is used to rotate the hinge parts to be processed around the processing table.

[0007] A vibrating feeder is set on the side of one end of the processing table and vibrates to feed materials towards the processing table.

[0008] Automatic clamping fixtures are connected at equal intervals to the chain plate rotation mechanism. The automatic clamping fixtures clamp the parts and, as the chain plate rotation mechanism rotates, they are transferred from the starting end of the processing table to the end and then back to the starting end.

[0009] The loading robot is positioned between the vibrating loading plate and the processing table to remove parts from the front end of the vibrating loading plate and place them onto the automatic clamping fixture.

[0010] Furthermore, a chain plate rotation mechanism is installed in the middle of the processing table. The chain plate rotation mechanism includes a motor, a transmission chain, shaft gears, and chain plates. Two sets of shaft gears are respectively provided at both ends of the processing table. The two transmission chains are meshed with two upper shaft gears and two lower shaft gears. The motor is fixedly installed at the end of the processing table and is connected to the shaft gear at one end. The motor drives the transmission chain to rotate around the processing table. Multiple equidistant automatic clamping fixtures are installed along the entire length of the transmission chain. Multiple chain plates are installed on the chain segments between the automatic clamping fixtures. The two sides of the chain plates are fixedly connected to the two transmission chains respectively.

[0011] Furthermore, the automatic clamping fixture includes a base plate, a column, an upper positioning plate, a side positioning plate, and a top column assembly. The base plate is a rectangular plate connected to two transmission chains. A column is provided on the base plate, and the upper positioning plate is fixedly connected to the top of the column. The front end of the upper positioning plate is provided with a first positioning hole and a second positioning hole. A side positioning plate is connected to the side of the column, and a third positioning hole is provided on the side positioning plate. The top column assembly is located directly below the first positioning hole and is fixedly mounted on the base plate. The space enclosed by the top column assembly, the side positioning plate, and the upper positioning plate is the clamping area for the part. The side of the hinge part is close to the side positioning plate, and the top column assembly presses against the shaft hole end of the hinge part from below. The bottom plane of the hinge part presses against the lower surface of the upper positioning plate.

[0012] Furthermore, the top column assembly includes a guide sleeve, a guide column, and a limiting spring. The guide sleeve is fixedly connected to the base plate, and the guide column is slidably connected to the center of the guide sleeve. The guide column passes through the guide sleeve and the base plate. A limiting spring is provided between the guide column and the guide sleeve. Under the action of the limiting spring, the guide column can float up and down within the guide sleeve. The clamping force of the limiting spring acts on the shaft hole end of the hinge part through the guide column.

[0013] Furthermore, the inner side of the side positioning plate is provided with an R-angle positioning arm, the front end of which is arc-shaped. The back of the hinge part abuts against the R-angle positioning arm. The upper positioning plate, the side positioning plate, and the R-angle positioning arm position the hinge part from the top, side, and back directions, respectively.

[0014] Furthermore, the processing table is provided with six hole station covers at equal intervals along its length. The hole station covers are positioned above the transmission chain. Each hole station cover is provided with a set of hole processing equipment above or on both sides. As the transmission chain rotates, the automatic clamping fixture passes through the six hole station covers in sequence. The corresponding hole processing equipment performs reaming, tapping, or chamfering on the hinge parts inside the automatic clamping fixture.

[0015] Furthermore, the top or side surface of the hole workstation cover is provided with holes for the processing end of the hole processing equipment to extend into and process the hinge parts inside the cover; the hole workstation cover is also provided with one or more water spray nozzles, which are aimed at the inside of the cover through the holes. When the hole processing equipment is processing, the water spray nozzles spray water to cool the processing area.

[0016] Furthermore, the starting end of the processing table is provided with an automatic unloading mechanism and a finished product chute. The automatic unloading mechanism is located adjacent to the transmission chain, and the upper end of the finished product chute is opposite to the automatic unloading mechanism, while the lower end extends downward to the side of the processing table. The automatic unloading mechanism includes a fixed support plate, a lead screw module, a rotary cylinder, and a pneumatic gripper. The fixed support plate is fixedly mounted on the processing table, and the fixed support plate is provided with a lead screw module perpendicular to the transmission direction. The lead screw module is connected to the rotary cylinder, which is simultaneously slidably connected to the fixed support plate. The rotary cylinder is connected to the pneumatic gripper through an L-shaped plate. The front end of the pneumatic gripper extends into the automatic clamping fixture to clamp the hinge part. After clamping the hinge part, the pneumatic gripper slides to the other end and rotates, thus placing the hinge part into the finished product chute for unloading.

[0017] Furthermore, a chip removal mechanism is provided below the frame. The chip removal mechanism includes a chip removal channel, a chip removal power module, and a chip collection cart. The chip removal channel is set along the entire length of the transmission chain. The chips generated by the processing of the six hole workstation covers all fall into the chip removal channel at the bottom. A chip collection cart is provided at the end of the chip removal channel. The chip removal power module is connected to the chip removal channel. The chip removal power module transports the chips in the chip removal channel to the end. The chips fall from the end into the chip collection cart and are collected.

[0018] Furthermore, the protective cover assembly includes fixed baffles and sliding door panels. The two fixed baffles are respectively fixedly installed in front of and behind the six-hole workstation protective cover, and the sliding door panels are slidably connected to both sides of the processing table.

[0019] The beneficial effects of this utility model are as follows: 1) This utility model can automatically feed door hinge parts, automatically process each hole in sequence, automatically unload, and automatically collect dust, without the need for manual assistance throughout the process, and has the advantages of high processing efficiency and high processing accuracy; 2) The chain plate rotation mechanism can rotate the automatic clamping fixture around the processing table, and the parts with completed hole processing can rotate back to the feeding end from below the table, and the unloading work is completed by the automatic unloading mechanism. In this way, the feeding and unloading positions can be set at the same end of the processing table, requiring only one worker. The worker can simultaneously pay attention to the replenishment of parts at the feeding end and the transfer of parts at the unloading end, reducing the reliance on manual labor; 3) In the automatic clamping fixture, the upper positioning plate, side positioning plate, and R-angle positioning arm position the hinge parts from three directions, while the top column assembly can automatically position the parts. When the loading robot picks up and puts down parts, the limit spring in the top column assembly automatically extends and retracts to push the material, making it easy for the loading robot to load the material and for the pneumatic gripper to pick it up. It also has a firm clamping effect, which can keep the hinge parts stable during the transmission process; 4) The six hole station guards set along the transmission chain are equally spaced. Each hole station guard performs a hole processing operation. Through the hole processing equipment set above, the two bottom holes, one shaft hole and one pin hole of the hinge parts can be reamed, chamfered and other operations. The six stations can work at the same time to improve the processing efficiency. The water spray head sprays water to cool the processing area to ensure the processing quality. The parts are always automatically clamped and fixed by the fixture during the switching between each station, avoiding the accuracy error caused by repeated clamping and alignment. The hole processing has a high processing accuracy and the yield rate is greatly improved. Attached Figure Description
