Description

Technical Field

Limiting grooves are formed at both the front and rear ends of the operating table. Sliding grooves are formed at the top and bottom of the inner cavity of the limiting grooves, and two sliders are slidably connected inside the sliding grooves. A connecting rod is fixedly connected to one side of each slider, and a fixing plate is fixedly connected to the inner side of the connecting rod.

In this engineering material cutting device, when the operator pushes the fixing plate inward, the connecting rods are connected to both sides of the fixing plate, and the sliders are connected to the inner side of the bottom of the connecting rods. The sliders slide within the limiting grooves formed on the front and rear sides of the base, allowing the operator to push the two fixing plates to fix materials of different widths for easier operation.

[0004] The aforementioned cutting device cannot limit the angle between the cutting equipment and the material, nor the cutting inclination, and cannot meet the specific angle requirements of the cut surface. In addition, during the cutting process, the clamps on both sides may obstruct the movement of the cutting equipment, or even cause damage to the cutting equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a material cutting device for highway bridge construction, which solves the problems of the inability to adjust the cutting angle and the fixed structure blocking the movement of the cutting equipment.

[0014] Beneficial effects

[0015] This invention provides a material cutting device for highway bridge construction. Compared with the prior art, it has the following advantages:

[0016] (1) The cutting device for materials used in highway bridge construction drives the limit plate to rotate through the transmission motor, which can freely adjust the angle between the profile and the cutting machine. The motor locking function ensures the stability of the angle. On the other hand, the stepper motor drives the adapter to rotate to realize the macro tilt of the cutting machine. The two adjustment methods work together to meet the cutting needs of various oblique surfaces and chamfers in highway bridge construction. The mechanical constraints and power locking ensure the angle stability of the cutting process. This effectively solves the problem of single angle adjustment and poor adaptability of traditional devices, and greatly improves the processing quality and efficiency of complex profiles.

[0017] (2) This cutting device for highway bridge construction materials, through the setting of the limiting plate, allows the cutting machine to be suspended to the side via the connecting frame and the transfer frame, thus initially forming a spatial separation. The support plate is provided with avoidance holes for the cutting tool to pass through and avoid contact with the support plate. In terms of motion coordination, the rotation range of the limiting plate is preset and limited to a fixed plane by ball bearings, so as not to touch the side cutting machine; the cutting machine tilts and adjusts to move around the axis of the connecting frame, and the trajectory does not intersect with the limiting components. The sliding range of the clamping plate is limited to the clamping range by linear bearings. The cutting point of the profile is located on the right side of the limiting plate, always below or to the side of the tool, and does not enter the cutting path. Attached Figure Description

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a material cutting device for highway bridge construction, including a base plate 1, and a cutting mechanism 2 arranged above the base plate 1.

[0025] The limiting assembly 21 includes a support plate 211 fixedly installed above the base plate 1. A ball bearing 212 is fitted into the center of the support plate 211. A drive motor 213 is fixedly installed above the support plate 211. A synchronous pulley 214 is fixedly installed on the outer side of the shaft of the drive motor 213. A synchronous belt 215 is fitted into the outer side of the synchronous pulley 214. A limiting plate 216 is inserted above the ball bearing 212. A limiting frame 217 is fixedly installed above the limiting plate 216. Linear bearings 218 are fitted into both sides of the limiting frame 217. A clamping plate 219 is inserted into one side of the linear bearings 218. A transmission block 2110 is fitted into the center of the limiting frame 217. Inside the support plate 211, a lead screw 2111 is installed. The shaft of the drive motor 213 passes through the support plate 211. The synchronous pulley 214 and the synchronous belt 215 are located below the support plate 211. The limiting plate 216 is rotatably connected to the support plate 211 through the ball bearing 212. The bottom end of the limiting plate 216 is also fixedly installed with the synchronous pulley 214. The two ends of one side of the clamping plate 219 are provided with columnar structures. The columnar structures of the clamping plate 219 are inserted into the linear bearing 218. The clamping plate 219 is slidably connected to the limiting frame 217 through the linear bearing 218. The transmission block 2110 is movably connected to the lead screw 2111. The end of the lead screw 2111 is rotatably connected to the clamping plate 219.

[0026] Specifically, the base plate 1 can restrict the position of the cutting mechanism 2, and the support plate 211 restricts the position between the drive motor 213 and the limiting plate 216 to prevent the limiting plate 216 from affecting the transmission of the synchronous belt 215 when it rotates. The drive motor 213 can drive the limiting plate 216 to rotate through the synchronous pulley 214 and the synchronous belt 215 to adjust the angle between the profile above the limiting plate 216 and the cutting tool of the cutting machine 223. The limiting frame 217 can restrict the direction of movement of the clamping plate 219 through the linear bearing 218. Since one end of the lead screw 2111 is rotatably connected to the clamping plate 219, the lead screw 2111 will be restricted by the transmission block 2110 when it rotates to drive the clamping plate 219 to move, so that the clamping plate 219 and the limiting plate 216 can clamp the profile to prevent the profile from moving during the cutting process. One side of the support plate 211 is provided with an opening structure for the cutting tool of the cutting machine 223 to pass through.

[0027] The drive assembly 22, located above the limiting assembly 21, is used for cutting profiles. The drive assembly 22 includes a connecting frame 221 fixedly installed on one side of the support plate 211. An adapter frame 222 is movably installed above the connecting frame 221. A cutting machine 223 is movably installed above the adapter frame 222. A torsion spring 224 is inserted into the bottom end of the cutting machine 223. The drive assembly 22 also includes a stepper motor 225 fixedly installed above the base plate 1. The adapter frame 222 and the connecting frame 221 are rotatably connected. The cutting machine 223 and the adapter frame 222 are rotatably connected. The rotation axis of the adapter frame 222 and the rotation axis of the cutting machine 223 are perpendicular to each other. One end of the torsion spring 224 is fixedly connected to the cutting machine 223 and the other end is fixedly connected to the adapter frame 222. The rotating shaft of the stepper motor 225 is fixedly connected to one end of the adapter frame 222 by insertion.

[0028] Specifically, the rotating shaft of the stepper motor 225 is fixedly connected to one end of the adapter frame 222. The stepper motor 225 can drive the adapter frame 222 to rotate to adjust the tilt angle of the cutter 223. The cutter 223 and the adapter frame 222 form a rotatable connection, and the initial angle of the cutter 223 is limited by the torsion spring 224 so that the cutter 223 can rotate to the initial position under the drive of the torsion spring 224 after the cutting is completed.

[0029] Specifically, the drive motor 213 and the stepper motor 225 are model AM17HD. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] During operation, the profile to be cut is placed on the limiting plate 216, and the lead screw 2111 is rotated. Since the transmission block 2110 and the lead screw 2111 are threaded together, and the cylindrical structures at both ends of the clamping plate 219 are guided and constrained by the linear bearings 218, when the lead screw 2111 rotates, the transmission block 2110 drives the clamping plate 219 to slide along the linear bearings 218, and finally works with the limiting plate 216 to clamp the profile, restricting its translational freedom. The transmission motor 213 is started, and the motor shaft drives the top synchronous wheel 214, which is linked to the bottom synchronous wheel 214 of the limiting plate 216 through the synchronous belt 215. Since the limiting plate 216 forms a rotating pair with the support plate 211 through the ball bearing 212, the limiting plate 216 and the profile rotate on a fixed axis with the synchronous wheel 214, adjusting the spatial angle between the profile and the cutting tool of the cutting machine 223. Once the target angle is reached, the drive motor 213 brakes and locks. Relying on the transmission constraint of the synchronous belt 215 and the motor's locking force, the angular position of the limit plate 216 after rotation is locked, ensuring the included angle remains stable during cutting. The stepper motor 225's shaft is fixedly connected to the adapter frame 222. When the motor operates, the adapter frame 222 rotates around the connecting frame 221, driving the cutting machine 223 to achieve macroscopic tilt angle adjustment. The cutting machine 223 and the adapter frame 222 are connected by a rotating pair and are initially constrained by the pre-tension of the torsion spring 224. After the angle adjustment is completed, the power source of the cutting machine 223 is started. The handle on the top of the cutting machine 223 drives the cutting machine 223 to rotate, so that the cutting tool of the cutting machine 223 cuts into the profile. During the cutting process: the torsion spring 224 buffers the cutting reaction force on the tool and suppresses angle drift; the limiting plate 216 and the clamping plate 219 rely on the motor locking and mechanical clamping force to continuously constrain the translation and rotation freedom of the profile; so as to meet the complex requirements of beveled surfaces and chamfers in bridge construction and ensure cutting accuracy and efficiency.
