Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of waste edge processing equipment, specifically relating to a fully automatic edge trimming machine for automotive parts. Background Technology
[0002] like Figure 10 The automotive parts shown require a rubber coating to be applied to certain parts of their surface after production. The rubber coating is applied to the surface of the workpiece through a vulcanization process. Rubber flash will form at the inner and outer edges of the workpiece, extending beyond the workpiece contour. This can lead to assembly interference and inaccurate alignment issues later on.
[0003] However, existing edge-cutting equipment for rubber flash has the following drawbacks during use: 1. Existing technologies are mostly single-machine, single-processing modes. The loading, positioning, processing, and unloading processes all require manual operation, resulting in low automation, discontinuous production, and difficulty in meeting the needs of large-scale production; 2. During processing, the generated waste chips need to be continuously blown away manually. The waste chips accumulate on the workpiece surface or near the cutting tool, which can easily cause secondary scratches or tool jamming, affecting the processing quality of the workpiece; those skilled in the art urgently need to solve the above technical problems.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0038] like Figure 1-4 As shown, this utility model provides a fully automatic edge trimming machine for automotive parts, comprising:
[0039] The frame 1 is provided with a cutting station, and a workpiece placement and positioning area is provided corresponding to the cutting station. A waste blowing mechanism 2 is provided around the workpiece placement and positioning area. A loading area and a unloading area are provided on the left and right sides of the cutting station, respectively.
[0040] Automatic edge cutting device 3 includes a blade 31, a tilting mechanism 32 and a displacement mechanism 33. The displacement mechanism 33 drives the blade 31 to move along its own axis to the workpiece placement and positioning area and cuts the edge of the rotating workpiece. The tilting mechanism 32 drives the blade 31 and the displacement mechanism 33 to rotate as a whole by tilting angle.
[0041] The aforementioned automatic edge trimming device 3 is provided in two sets, corresponding to the outer edge and inner edge of the workpiece, respectively;
[0042] The automatic material handling device 4 includes a robotic arm 42 connected to a robotic arm 41, and a clamping mechanism 43 installed at the free end of the robotic arm 42. The robotic arm 42 drives the clamping mechanism 43 to automatically reciprocate between the loading area, the edge cutting station and the unloading area.
[0043] The working principle and beneficial effects of the above embodiments are as follows:
[0044] The robotic arm 42 of the automatic material handling device 4 of this utility model drives the clamping mechanism 43 to first move to the loading area, and accurately grab the workpiece to be processed through the clamping mechanism 43. Then the robotic arm 42 drives the workpiece to move to the workpiece placement and positioning area of the cutting station, and places the workpiece stably and completes the positioning.
[0045] Two sets of automatic edge trimming devices 3 start working together to target the inner and outer edges of the workpiece. The displacement mechanism 33 drives the blade 31 to move along its own axis, so that the blade 31 is precisely close to the edge to be trimmed of the workpiece. The yaw mechanism 32 adjusts the cutting angle of the blade 31 according to the required cutting angle of the workpiece to adapt to different processing requirements. The workpiece rotates synchronously in the positioning area, and the blade 31 contacts the edge of the rotating workpiece to complete the edge trimming process.
[0046] During the cutting process, the waste blowing mechanism 2 around the workpiece placement and positioning area is activated to promptly blow the waste generated during cutting away from the processing area, preventing waste accumulation from affecting processing accuracy or damaging the blade 31;
[0047] After the edge trimming is completed, the clamping mechanism 43 of the automatic loading and unloading device 4 moves back to the edge trimming station, grabs the processed workpiece, and is transferred by the robotic arm 42 to the unloading area for placement, completing the processing cycle of a single workpiece and realizing continuous batch processing.
[0048] The workpiece is precisely fixed by the positioning area, and with the precise drive of the displacement mechanism 33, the relative position of the blade 31 and the edge of the workpiece is stable. The yaw mechanism 32 can precisely adjust the cutting angle and improve the consistency of workpiece processing.
[0049] Two sets of automatic edge trimming devices 3 are used to process the inner and outer edges of the workpiece respectively. Multiple edge trimming parts can be completed in one positioning, improving processing efficiency. Automatic loading and unloading device 4 realizes full automation of workpiece loading, positioning and unloading, reducing manual intervention and lowering labor costs.
[0050] In one embodiment,
[0051] like Figure 5As shown, a rotary feeding device 5 is provided in the above-mentioned feeding area, which includes a multi-station indexing plate 51 horizontally installed on the frame 1. Each station is provided with a positioning post 52 for stacking workpieces. Each positioning post 52 is fitted with a workpiece support tray 53. A lifting mechanism 54 is installed at one of the positioning posts 52. The lifting mechanism 54 contacts the support tray 53 and drives the workpieces on the support tray 53 to move upward one by one, so that the clamping mechanism 43 can clamp the workpieces one by one. The lifting mechanism 54 is arranged close to the automatic loading and unloading device 4.
[0052] The multi-station indexing plate 51 is horizontally mounted on the frame 1. The positioning columns 52 of its multiple stations are used to stack workpieces. Operators can pre-load batch workpieces onto each positioning column 52 in sequence. The workpieces are carried by the support tray 53 to achieve pre-storage of the workpieces.
[0053] The indexing plate 51 can rotate around the central axis. After the workpiece on the positioning column 52 near the lifting mechanism 54 is removed, the indexing plate 51 rotates to move the positioning column 52 of the next fully loaded workpiece to the lifting mechanism 54, ensuring the continuity of feeding.
[0054] The aforementioned lifting mechanism 54 is a screw jack, which is existing technology and will not be described in detail here. The lifting mechanism 54 contacts the support tray 53 of the current workstation and drives the support tray 53 upward to move the stacked workpieces upward one by one. The lifting height each time is equal to the thickness of a single workpiece, so that the topmost workpiece is always at a fixed height that the clamping mechanism 43 can grasp.
[0055] The clamping mechanism 43 of the automatic material handling device 4 moves to the corresponding position of the lifting mechanism 54 according to the rhythm. After grabbing the top workpiece, the lifting mechanism 54 immediately pushes the next workpiece upward, waiting for the next grab.
[0056] The multi-station indexing plate 51 can pre-store multiple sets of stacked workpieces. When the workpieces at one station are exhausted, the indexing plate 51 quickly switches to the next station, avoiding frequent downtime due to manual replenishment, and is suitable for long-term continuous batch production.
[0057] In one embodiment,
[0058] like Figure 6 As shown, an internal support chuck device 6 is provided in the workpiece placement and positioning area, which includes a hollow chuck seat 61, a chuck body 62, a telescopic mechanism 63 and a rotating mechanism 64. The chuck body 62 is located in the hollow part of the hollow chuck seat 61. During edge cutting, the telescopic mechanism 63 pushes the hollow chuck seat 61 so that the head of the chuck body 62 inside extends out of the hollow part to support and clamp the workpiece to be processed. The rotating mechanism 64 drives the chuck body 62 to rotate.
[0059] When the automatic loading and unloading device 4 places the workpiece to be processed in the positioning area, the telescopic mechanism 63 pushes the hollow chuck seat 61 to move. Since the chuck body 62 is located in the hollow part of the hollow chuck seat 61, the head of the chuck body 62 extends out of the hollow area and contacts the inner wall of the workpiece.
[0060] The head of the chuck body 62 is designed with a three-jaw expansion structure. During the extension process, it expands outwards simultaneously, tightly supporting the inner wall of the workpiece, realizing the radial positioning and clamping of the workpiece, and preventing the workpiece from shaking during processing.
[0061] During the edge cutting stage, the rotating mechanism 64 drives the chuck body 62 to rotate, and the workpiece rotates synchronously with the chuck body 62, which, together with the movable blade 31, completes the cutting of the workpiece edge.
[0062] After the trimming is completed, the telescopic mechanism 63 reverses the drive to reset the hollowed-out chuck seat 61, the head of the chuck body 62 retracts into the hollowed-out part, loosens the tension on the inner wall of the workpiece, and the clamping mechanism 43 of the automatic loading and unloading device 4 grabs the workpiece and moves it to the unloading area.
[0063] In one embodiment,
[0064] like Figure 6 , 7 As shown, the above-mentioned waste blowing mechanism 2 includes a plurality of air blowing pipes 21 installed on the hollow chuck seat 61 and arranged in parallel, and a collection bin 22 installed on the frame 1 and having an opening on one side. The opening end of the collection bin 22 extends into the hollow chuck seat 61 and is arranged directly opposite the air blowing pipes 21. A collection box 23 is provided at the material drop port directly below the collection bin 22.
[0065] During the edge trimming process, multiple air blowing pipes 21 installed on the hollow chuck seat 61 are started simultaneously. The air blowing direction of the air blowing pipes 21 is precisely aligned with the edge trimming area of the workpiece, and the waste generated during cutting is blown directly to the opening end of the collection bin 22. The waste enters the bin body through the opening of the collection bin 22 and falls into the collection box 23 at the bottom under the action of gravity, realizing the centralized storage of waste.
[0066] Multiple air pipes 21 arranged in parallel can cover a wider blowing range, adapting to the waste cleaning needs of different parts of the workpiece.
[0067] In one embodiment,
[0068] like Figure 8 As shown, the clamping mechanism 43 includes a clamping plate 431 installed at the free end of the robotic arm 42, two pneumatic grippers 432 installed side by side on the clamping plate 431, and an abutment block 433 installed at the center inside the pneumatic grippers 432; the two pneumatic grippers 432 are symmetrical about the rotation center of the robotic arm 42.
[0069] Pneumatic grippers 432 are mounted side by side on clamping plate 431 in a symmetrical layout. The grippers are driven to open and close by compressed air to grasp and release the workpiece. Abutment block 433 is installed at the center of the interior of each pneumatic gripper 432 to contact the workpiece surface during the gripping process, providing stable support and positioning reference.
[0070] When the robotic arm 42 moves the clamping mechanism 43 to the cutting station, one of the pneumatic grippers 432 can accurately grasp the workpiece that has been cut, while the other pneumatic gripper 432 simultaneously places the new workpiece to be processed onto the inner support chuck device 6, saving displacement and action time in a single cycle.
[0071] In one embodiment,
[0072] like Figure 9 As shown, a feeding device 7 is provided in the feeding area, which includes a feeding frame 71, a conveyor belt 72 installed on the feeding frame 71 and conveying workpieces in a preset direction, and a V-shaped stop block 73 installed at the end of the conveyor belt 72.
[0073] When the clamping mechanism 43 of the automatic loading and unloading device 4 moves the finished workpiece from the cutting edge to the unloading area, the workpiece is placed at the starting end of the conveyor belt 72. The conveyor belt 72 is driven by a motor to smoothly transport the workpiece along the preset direction to its end, where it is blocked by the V-shaped stop 73 at the end, realizing the orderly temporary storage of the finished product, which is convenient for subsequent manual or automated equipment to collect.
[0074] In one embodiment,
[0075] For example Figure 2 As shown, the above-mentioned automatic edge cutting device 3 also includes a vertical moving mechanism 34 installed below the displacement mechanism 33, and a horizontal moving mechanism 35 installed below the vertical moving mechanism 34.
[0076] The horizontal moving mechanism 35 and the vertical moving mechanism 34 drive the entire automatic edge cutting device 3 to move in two dimensions in the horizontal plane, ensuring that the blade 31 is aligned with the point to be cut.
[0077] In summary:
[0078] This utility model discloses a fully automatic edge trimming machine for automotive parts. The design includes a pre-storage feeding device with a rotating feeding device, synchronous material handling by dual pneumatic grippers, automatic positioning and rotation of the inner support chuck, synchronous processing by dual edge trimming devices, and automatic waste blowing and conveyor belt unloading, forming a complete closed loop.

[0079] This utility model is designed with displacement and yaw mechanism in conjunction with lateral and vertical movement mechanism to achieve precise control of blade angle and position.
