Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, and in particular to a fixing fixture for aluminum door welding and milling. Background Technology

[0002] In the production and processing of aluminum doors, the welding and milling process places extremely high demands on the positioning accuracy and clamping stability of the workpiece, directly affecting the dimensional accuracy, welding strength, and surface finish of the product. Currently, the fixed tooling fixtures used in aluminum door welding and milling have many technical limitations, making it difficult to meet the demands for efficient, precise, and flexible production.

[0003] In existing technologies, traditional aluminum door clamping relies heavily on manually operated mechanical fixtures, using bolts, pressure plates, and other components for fixation. These fixtures are not only inefficient, requiring operators to spend considerable time adjusting the workpiece position and tightening the fixtures, but also necessitate disassembling and readjusting the fixture structure when changing to different aluminum door specifications, resulting in poor adaptability and severely limiting production line changeover speed. Furthermore, during manual positioning, the alignment of the aluminum door's reference point depends primarily on the operator's experience and judgment, lacking a precise detection and feedback mechanism. This can easily lead to dimensional deviations due to positioning errors, potentially causing workpiece scrap.

[0004] In terms of workpiece adjustment, the support surface of traditional fixtures is mostly a fixed plane. When the aluminum door moves or rotates on it, the friction is large. Operators need to apply a large external force to complete the angle or position adjustment, which not only increases the labor intensity, but also makes it difficult to guarantee the adjustment effect.

[0005] To address this, we propose a fixture for fixing aluminum door welding and milling. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an aluminum door welding and milling fixing fixture.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum door welding and milling fixing fixture, including a frame, wherein a plurality of first pneumatic lifting components are uniformly fixedly connected to the left outer wall of the frame, a backing is fixedly connected to the top of each of the plurality of first pneumatic lifting components, and a contact sensor is fixedly installed on the right outer wall of each of the plurality of backings.

[0008] A servo transverse component is embedded in the top of the frame on the left front side. An L-shaped seat is fixedly connected to the movable end of the servo transverse component. A first cylinder is fixedly installed on the inner wall of one side of the frame, and the piston rod of the first cylinder is connected to the servo transverse component.

[0009] The top of the frame is fitted with several ball bearing plates, and the ball bearing plates are all mounted together with the frame with a second pneumatic lifting assembly.

[0010] Two pneumatic clamping assemblies are fixedly connected to the rear outer wall of the frame.

[0011] Furthermore, each of the first and second pneumatic lifting components includes a fixed base, which is fixedly connected to the frame. A second cylinder is fixedly connected to the bottom of the fixed base, and the piston rod of the second cylinder passes through the fixed base. An adjacent support is fixedly installed on the top of the piston rod of the second cylinder. Two first guide rods that extend to the bottom are symmetrically provided on the top of the fixed base. The first guide rods are slidably connected to the fixed base, and an adjacent support is fixedly installed on the top of the two first guide rods. The first guide rods cooperate with the fixed base to have a limiting and guiding effect.

[0012] Furthermore, the servo traverse assembly includes a track seat, which is embedded in the top of the frame and fixedly installed on the top of the piston rod of the first cylinder. A servo motor is fixedly installed at the front end of the track seat, and a lead screw is fixedly connected to the drive shaft of the servo motor. The lead screw is rotatably connected to the track seat. A slide is threaded onto the outer surface of the lead screw, and the slide is slidably connected to the track seat and fixedly installed at the bottom of the L-shaped seat. The track seat has a limiting function for the slide, which can ensure the stability of the movement of the track seat.

[0013] Furthermore, two second guide rods are symmetrically fixedly connected to the bottom of the track seat, and the second guide rods are slidably connected to the frame. The second guide rods cooperate with the frame to have a limiting and guiding effect, which can ensure the stability of the track seat movement.

[0014] Furthermore, each of the ball bearing trays includes a tray, which is embedded in the top of the frame and fixedly installed on the top of the piston rod of the adjacent second cylinder and the two first guide rods. A number of support balls are slidably embedded in the top of the tray, and the support balls can reduce the moving resistance of the aluminum door.

[0015] Furthermore, the two pneumatic clamping assemblies include dual-axis cylinders, which are fixedly connected to the frame. The movable end of the dual-axis cylinder is fixedly connected to a pressure seat, and the dual-axis cylinder itself has a limiting function to ensure the stability of the pressure seat movement.

[0016] The beneficial effects of this utility model are:

[0017] In use, this utility model achieves the positioning and clamping of aluminum doors through the coordinated action of multiple sets of pneumatic lifting components, contact sensors and servo traverse components. The ball bearing design facilitates manual angle adjustment, the contact sensor ensures positioning accuracy, and the L-shaped seat and pneumatic clamping components form a bidirectional clamping, significantly improving the clamping efficiency and processing stability of aluminum doors. At the same time, the modular structure takes into account the flexible production needs of aluminum doors of different sizes. Attached Figure Description

[0026] like Figures 1-4As shown, this relates to an aluminum door welding and milling fixing fixture, including a frame 1, which serves as the basic support structure for the entire fixture, ensuring overall rigidity and stability. Several first pneumatic lifting components are uniformly fixedly connected to the left outer wall of the frame 1. Each of the first pneumatic lifting components has a backing plate 10 fixedly connected to its top. Contact sensors 12 (model ZCB204AH-W, referenced) are fixedly installed on the right outer wall of each backing plate 10, used to detect whether the aluminum door fits against the backing plate 10. Several ball bearing plates are embedded in the top of the frame 1. Each of the ball bearing plates and the frame 1 is equipped with a second pneumatic lifting component. Both the first and second pneumatic lifting components include a fixing seat 17, and the fixing seat 17 is connected to the frame... The frame 1 is fixedly connected, and the bottom of the fixed base 17 is fixedly connected to the second cylinder 11. The piston rod of the second cylinder 11 passes through the fixed base 17, and the adjacent backrest 10 is fixedly installed on the top of the piston rod of the second cylinder 11. The top of the fixed base 17 is symmetrically provided with two first guide rods 16 that pass through to the bottom. The first guide rods 16 are slidably connected to the fixed base 17, and the adjacent backrest 10 is fixedly installed on the top of the two first guide rods 16. Several ball bearing trays include trays 6, and the trays 6 are embedded in the top of the frame 1 and fixedly installed on the top of the piston rod of the adjacent second cylinder 11 and the top of the two first guide rods 16. Several support balls 5 are slidably embedded in the top of the trays 6. The support balls 5 are made of GCr15 bearing steel.

[0027] A servo transverse component is embedded in the top of the frame 1 on the left front side. The movable end of the servo transverse component is fixedly connected to an L-shaped seat 8. A first cylinder 9 is fixedly installed on the inner wall of one side of the frame 1, and the piston rod of the first cylinder 9 is connected to the servo transverse component. The servo transverse component includes a track seat 13, which is embedded in the top of the frame 1 and fixedly installed on the top of the piston rod of the first cylinder 9. A servo motor 4 is fixedly installed at the front end of the track seat 13. A lead screw 14 is fixedly connected to the drive shaft of the servo motor 4, and the lead screw 14 is rotatably connected to the track seat 13. A slide 15 is threaded on the outer surface of the lead screw 14, and the slide 15 is slidably connected to the track seat 13 and fixedly installed at the bottom of the L-shaped seat 8. Two second guide rods 7 are symmetrically fixedly connected to the bottom of the track seat 13, and the second guide rods 7 are slidably connected to the frame 1. The servo motor 4 is a Panasonic MINAS A6 series with encoder feedback.

[0028] Two pneumatic clamping assemblies are fixedly connected to the rear outer wall of the frame 1. The two pneumatic clamping assemblies include a dual-axis cylinder 2, and the dual-axis cylinder 2 is fixedly connected to the frame 1. The movable end of the dual-axis cylinder 2 is fixedly connected to a pressure seat 3. The outer surface of the pressure seat 3 is coated with polyurethane to avoid damaging the surface of the aluminum door.

[0029] Aluminum door loading and initial positioning:

[0030] The second pneumatic lifting assembly (including the second cylinder 11 and the first guide rod 16) is activated, pushing the tray 6 and the support ball bearings 5 ​​to rise to the preset height. The operator places the aluminum door horizontally on the support ball bearings 5 ​​and easily adjusts its position using their low-friction characteristics. At the same time, the first cylinder 9 is activated, driving the servo traverse assembly (track seat 13, servo motor 4, lead screw 14, slide 15, and second guide rod 7) to descend, so that the L-shaped seat 8 is lower than the plane of the aluminum door, avoiding interference with the adjustment of the aluminum door.

[0031] Aluminum door adjustment:

[0032] The operator manually rotates the aluminum door, using the low-friction characteristics of the support ball bearing 5 to adjust it to the required processing angle.

[0033] Lateral reference positioning:

[0034] The first pneumatic lifting assembly (including the second cylinder 11 and the first guide rod 16) is activated, pushing the support 10 upward. Then, the operator pushes the aluminum door so that one side is pressed tightly against the support 10. After the contact sensor 12 detects the contact signal of the aluminum door, it feeds back to the control system. Subsequently, the first and second pneumatic lifting assemblies descend synchronously, causing the aluminum door to fall onto the processing reference surface of the frame 1, completing the initial positioning.

[0035] Lateral clamping and positioning:

[0036] The first cylinder 9 resets, causing the servo traverse assembly (track seat 13, servo motor 4, lead screw 14, slide 15, and second guide rod 7) to rise to its initial height, thereby resetting the L-shaped seat 8. The servo motor 4 drives the lead screw 14 to rotate, causing the slide 15 to move the L-shaped seat 8 laterally, pushing the aluminum door tightly against the pressure seat 3. Subsequently, the first cylinder 9 actuates a second time, causing the L-shaped seat 8 to descend and press against one side of the aluminum door. Simultaneously, the dual-axis cylinder 2 actuates, pushing the pressure seat 3 downwards to press against the aluminum door, ensuring processing stability.

[0037] Processing completed and reset:

[0038] After processing is completed, all components are reset. At this time, the staff can move the aluminum door. If the position of the aluminum door needs to be adjusted, the above steps are repeated to prepare the system for the next processing cycle.

[0039] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the dual-axis cylinder 2, the first cylinder 9, the second cylinder 11, and the contact sensor 12 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is merely to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
