Description

Technical Field

[0001] This utility model belongs to the field of hinge beam processing technology, specifically relating to a hinge beam processing cutting structure. Background Technology

[0002] A hinge beam is a mechanical structural component primarily used to connect two or more objects, allowing them to rotate relative to each other. Like the connector between a door and its frame, a hinge beam enables a door to open and close around an axis. In many mechanical devices, hinge beams play a similar crucial role, ensuring flexible rotation between different components to achieve the specific function of the entire device. The manufacturing method of a hinge beam depends on factors such as its material, size, shape, and precision requirements. Manufacturing methods for hinge beams include forging, casting, welding, and machining. For pre-formed hinge beams, cutting tools are needed to trim the rough or uneven surfaces.

[0003] Problems with existing technology:

[0004] For some heavy hinge beams, the connecting lugs formed by forging or casting need to be rotated to cut different sides of the lugs. When using some translational cutting equipment, not only is the installation and fixing cumbersome, but the rotation operation is also troublesome when other lugs need to be cut, thus reducing the cutting efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a machining structure for hinge beams that can solve the above-mentioned technical problems.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] This utility model provides a hinge beam machining cutting structure, including a base and a hinge beam body. The base is provided with a rotation mechanism for rotating and adjusting the hinge beam body. The base is provided with a shifting mechanism. The shifting mechanism is provided with a cutting mechanism corresponding to the connecting lugs on the hinge beam body. The shifting mechanism rotates in correspondence with a positioning plate provided on the base. A controller is installed on the positioning plate.

[0008] The rotating mechanism includes a rotating shaft rotatably mounted on a base, a support plate on the upper side of the rotating shaft, the hinge beam body placed on the support plate, a worm wheel located on the bottom surface of the base on the lower side of the rotating shaft, the worm wheel meshing with a worm gear located on the bottom surface of the base, and the worm gear connected to the output shaft of a rotating motor located on the bottom surface of the base.

[0009] The displacement mechanism includes a base plate and a central shaft rotatably mounted on the base. A rotating plate is connected to the upper end of the central shaft. The rotating plate is fixedly connected to one side of the base plate. An overlapping plate that overlaps with the positioning plate is provided on the other side of the base plate. A propulsion mechanism for pushing the cutting mechanism to move is provided on the base plate. An outward displacement mechanism for pushing the base plate to rotate is provided on the overlapping plate.

[0010] The aforementioned hinge beam machining and cutting structure involves placing the hinge beam body on a support plate and fixing it in place. A controller then controls a rotating motor to rotate, causing the connecting lugs on the hinge beam to rotate and align with the cutting mechanism. The controller then controls the retraction of an electric push rod on the outward movement mechanism, causing the push rod to rotate the base plate and the propulsion mechanism to align with the connecting lugs. Simultaneously, the cutting mechanism also aligns with the connecting lugs. The controller then controls the extension of a hydraulic push rod on the cutting mechanism, simultaneously moving the cutting tool downwards to cut the side of the connecting lugs. As cutting progresses, the controller starts a moving motor on the propulsion mechanism, which drives a lead screw to rotate. The lead screw moves a synchronous plate and two slide blocks along the slide rail, simultaneously moving the entire cutting mechanism. This causes the cutting tool to move and propel the cutting tool to cut the side of the connecting lugs. After processing one connecting lug, the controller extends the electric push rod to rotate the shifting mechanism and move the cutting mechanism away from the connecting lug. The controller then controls the rotating motor to rotate, causing the hinge beam to rotate. This rotation adjusts the other connecting lug to its corresponding position with the cutting mechanism for cutting.

[0011] Preferably, the propulsion mechanism includes two slide rails and slide blocks slidably mounted on the slide rails. Two sets of support plates are provided on the base plate, and side baffles are provided on both sides of each set of support plates. The two slide rails are detachably mounted on the two sets of support plates. A synchronization plate is detachably mounted between the two slide blocks. A lead screw is threaded onto the synchronization plate. The lead screw is rotatably mounted on the two side baffles. A pulley set is provided on the side of the lead screw away from the base. A mounting plate is provided on the bottom surface of one of the side baffles, and a moving motor is mounted on the mounting plate. The output shaft of the moving motor is connected to the pulley set for transmission.

[0012] Preferably, the bottom surface of the base plate and the two sets of support plates are provided with casters on both sides, and the bottom surface of the mounting plate is provided with small casters.

[0013] Preferably, the cutting mechanism includes two vertical plates and a hydraulic push rod. A fixing plate is provided on the lower side of each of the two vertical plates, and the two fixing plates are detachably mounted on a slide block. A connecting plate is provided on the upper side of each of the two vertical plates, and a support frame is detachably mounted on the connecting plate. A hydraulic push rod is provided on the upper bottom surface of the support frame. The connecting plate is movably sleeved with the lower side of the fixed end of the hydraulic push rod. A cutting tool is provided on the lower side of the extended end of the hydraulic push rod, and the cutting tool corresponds to the side of one of the connecting lugs on the hinge beam body.

[0014] Preferably, a second stabilizing plate is provided on the lower side of the two vertical plates, and a sliding hole plate is provided on the side of the connecting plate. The sliding hole plate is slidably connected to the first stabilizing plate provided on the lower side of the hydraulic push rod extension end through a formed sliding hole. A clamping plate is detachably provided on the side of the first stabilizing plate.

[0015] Preferably, the outward movement mechanism includes an electric push rod, with a rotating shaft provided at both the fixed end and the extended end of the electric push rod. The base is rotatably engaged with one of the rotating shafts corresponding to the fixed end of the electric push rod, and the positioning plate is rotatably engaged with the other rotating shaft corresponding to the extended end of the electric push rod.

[0016] Preferably, the base has multiple hemispherical grooves formed around the rotation axis, and ball bearings are rolled inside the hemispherical grooves, with the support plate rolling and overlapping the ball bearings.

[0017] The beneficial effects are:

[0018] This invention uses a rotating mechanism to drive a hinge beam to rotate, thereby aligning the connecting lugs on the hinge beam with the cutting tool on the lower cutting mechanism. Then, an electric push rod on the outer moving mechanism drives the shifting mechanism to rotate and align with the connecting lugs. The hydraulic push rod on the lower cutting mechanism can then be operated to cut the side of the connecting lugs. Simultaneously, the pushing mechanism moves and advances with the cutting progress, thereby driving the lower cutting mechanism to perform comprehensive cutting on the side of the connecting lugs. In this way, after cutting one connecting lug, the other connecting lug can be cut by rotation adjustment, improving the rotation adjustment efficiency and indirectly improving the cutting effect.

Detailed Implementation

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-5 As shown, a hinge beam machining cutting structure includes a base 1 and a hinge beam body 3. The base 1 is provided with a rotation mechanism for rotating and adjusting the hinge beam body 3. The base 1 is provided with a shifting mechanism 6. The shifting mechanism 6 is provided with a cutting mechanism 7 corresponding to the connecting lugs on the hinge beam body 3. The shifting mechanism 6 is rotatably corresponding to a positioning plate 5 provided on the base 1. A controller 4 is installed on the positioning plate 5. The output end of the controller 4 is electrically connected to the input ends of a rotating motor 11, a moving motor 609, a hydraulic push rod 705, and an electric push rod 612.

[0028] The rotating mechanism includes a rotating shaft 8 rotatably mounted on the base 1, a support plate 2 mounted on the upper side of the rotating shaft 8, a hinge beam body 3 placed on the support plate 2, a worm wheel 9 located on the bottom surface of the base 1 mounted on the lower side of the rotating shaft 8, the worm wheel 9 meshing with a worm 10 mounted on the bottom surface of the base 1, the worm 10 being connected to the output shaft of a rotating motor 11 mounted on the bottom surface of the base 1, the rotating motor 11 being a servo motor or a stepper motor, and an encoder being synchronously mounted thereon;

[0029] The shifting mechanism 6 includes a base plate 602 and a central shaft 614 rotatably mounted on the base 1. A rotating plate 601 is connected to the upper end of the central shaft 614. The rotating plate 601 is fixedly connected to one side of the base plate 602. An overlapping plate 611 is provided on the other side of the base plate 602 to cooperate with the positioning plate 5. The base plate 602 is provided with a propulsion mechanism for pushing the cutting mechanism 7 to move. The overlapping plate 611 is provided with an outward shifting mechanism for pushing the base plate 602 to rotate.

[0030] As an optional implementation, the propulsion mechanism includes two slide rail plates 603 and slide blocks 604 slidably mounted on the slide rail plates 603. Two sets of support plates 608 are mounted on the base plate 602, and side baffles 607 are respectively mounted on both sides of the two sets of support plates 608. The two slide rail plates 603 are detachably mounted on the two sets of support plates 608. A synchronization plate 605 is detachably mounted between the two slide blocks 604. A lead screw 606 is threaded onto the synchronization plate 605, and the lead screw 606 is rotatably mounted on the two slide blocks 604. On the side baffle 607, a pulley group 610 is provided on the side of the lead screw 606 away from the base 1. A mounting plate 616 is provided on the bottom surface of one of the side baffles 607. A moving motor 609 is provided on the mounting plate 616. The output shaft of the moving motor 609 is connected to the pulley group 610 for transmission. With this configuration, the moving motor 609 on the propulsion mechanism can drive the lead screw 606 to rotate, thereby driving the slide 604 and the cutting mechanism 7 to move as a whole, thus improving the moving and propulsion effect of the cutting mechanism 7.

[0031] See attached document Figure 3 and attached Figure 4 The bottom surfaces of the base plate 602 and the two sets of support plates 608 are equipped with casters 615 on both sides, and the bottom surface of the mounting plate 616 is equipped with smaller casters 615. This arrangement allows the casters 615 to form a moving support with the ground when the displacement mechanism 6 rotates, thereby improving the moving support effect of the displacement mechanism 6 in rotation adjustment.

[0032] See attached document Figure 5 The cutting mechanism 7 includes two vertical plates 702 and a hydraulic push rod 705. The lower sides of the two vertical plates 702 are respectively provided with fixed plates 701. The two fixed plates 701 are detachably mounted on the slide block 604. The upper sides of the two vertical plates 702 are provided with connecting plates 703. The connecting plates 703 are detachably mounted with support frames 704. The upper bottom surface of the support frames 704 is provided with hydraulic push rods 705. The connecting plates 703 are movably sleeved with the lower side of the fixed end of the hydraulic push rods 705. The lower side of the extended end of the hydraulic push rods 705 is provided with cutting tools 706. The cutting tools 706 correspond to the side of one of the connecting lugs on the hinge beam body 3.

[0033] Furthermore, a second stabilizing plate 710 is provided on the lower side of the two vertical plates 702, and a sliding hole plate 709 is provided on the side of the connecting plate 703. The sliding hole plate 709 is slidably connected to the first stabilizing plate 707 provided on the lower side of the extended end of the hydraulic push rod 705 through the formed sliding hole. A clamping plate 708 is detachably provided on the side of the first stabilizing plate 707. In this way, the clamping plate 708 can be used to form a sliding stabilizing effect on the first stabilizing plate 707, thereby improving the stability of the cutting tool 706 when it moves downward.

[0034] Furthermore, the outward movement mechanism includes an electric push rod 612, with a rotating shaft 613 at both the fixed end and the extended end of the electric push rod 612. The base 1 is rotatably engaged with one of the rotating shafts 613 corresponding to the fixed end of the electric push rod 612, and the positioning plate 5 is rotatably engaged with the other rotating shaft 613 corresponding to the extended end of the electric push rod 612. The positioning plate 5 is provided with a blocking plate to prevent the overlapping plate 611 from moving. This allows the overlapping plate 611 and the entire shifting mechanism 6 to be rotated and positioned by the blocking plate after the shifting mechanism 6 rotates, thereby improving the positioning effect after rotation adjustment.

[0035] Furthermore, the base 1 is formed with multiple hemispherical grooves centered on the rotating shaft 8, and ball bearings are rolled in the hemispherical grooves. The support plate 2 rolls and overlaps on the ball bearings. In this way, when the support plate 2 rotates, the rolling contact between the ball bearings and the base 1 can improve the rotational support of the support plate 2, thereby making it easier to rotate and support the weight of the hinge beam.

[0036] Using the above structure, the hinge beam body is placed on the support plate 2 and fixed. The controller 4 controls the rotation motor 11 to rotate, thereby driving the connecting lugs on the hinge beam to rotate and align with the cutting mechanism 7. Then, the controller 4 controls the electric push rod 612 on the outward movement mechanism to retract, causing the electric push rod 612 to drive the base plate 602 and the propulsion mechanism to rotate and align with the connecting lugs. At the same time, it drives the cutting mechanism 7 to also align with the connecting lugs. Then, the controller controls the hydraulic push rod 705 on the cutting mechanism 7 to extend, while driving the cutting tool 706 to move downward to cut the side of the connecting lugs. Then, as the cutting progresses, the controller controls the movement of the propulsion mechanism... When the motor 609 starts, it drives the lead screw 606 to rotate. The lead screw 606 drives the synchronous plate 605 and the two slide blocks 604 to move along the slide rail plate 603, and at the same time drives the lower cutting mechanism 7 to move as a whole. This drives the cutting tool 706 to move and perform cutting on the side of the connecting lug. After processing one connecting lug, the electric push rod 612 can be controlled to extend and drive the shifting mechanism 6 to rotate and drive the lower cutting mechanism 7 to disengage from the connecting lug. Then, the rotating motor 11 is controlled to rotate, thereby driving the hinge beam to rotate. The rotation adjusts the other connecting lug to the position corresponding to the lower cutting mechanism 7, so as to perform cutting on it.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
