[0003] There is an existing cutting device for metal product processing with a positioning mechanism (authorization announcement number CN217701601U) which has the following defects: the above-mentioned device uses the positioning blocks on the opposite sides of the positioning plate to simultaneously push the metal product in the arc-shaped groove toward the middle for rapid positioning. However, when the size of the metal product is smaller than the arc-shaped groove, the positioning blocks can only push and position the left and right sides of the metal product. Since the size of the metal product is smaller than the arc-shaped groove, the arc-shaped groove cannot abut and position the front and back sides of the metal product, resulting in inaccurate positioning of the metal product during cutting, thereby affecting the cutting efficiency of the metal product. For this reason, we propose the utility model. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please see attached Figure 1 -Attached Figure 4 A cutting device with a positioning mechanism comprises an operating table 1, a mounting groove 2 is provided on the top surface of the operating table 1, a positioning structure is provided on the top surface of the operating table 1, the positioning structure comprises two mounting plates 201 symmetrically arranged on the top surface of the operating table 1, movable plates 202 are hinged on both sides of the two mounting plates 201, a bidirectional screw rod 204 is rotatably arranged on the bottom surface of the operating table 1, the positive and negative threads of the bidirectional screw rod 204 are respectively threadedly connected with a fixing plate 203, and the top surfaces of the two fixing plates 203 are respectively fixed to the bottom surfaces of the two mounting plates 201.

[0022] In the embodiment, a driving motor is fixed on one side of the operating table 1, and the output end of the driving motor is fixed to one end of the bidirectional screw rod 204. Electric push rods 205 are fixed on the sides of the two mounting plates 201 that are away from each other. The telescopic ends of the electric push rods 205 are fixed to connecting plates 206. Adjustment bars 207 are hinged on both sides of the connecting plates 206. One end of the adjustment bar 207 is hinged to one side of the movable plate 202. Through the setting of the positioning structure, the staff places the workpiece on the operating table 1, starts the driving motor to drive the bidirectional screw rod 204 to rotate, and the rotation of the bidirectional screw rod 204 causes the two fixed plates 203 to drive the two mounting plates 201 approach each other. During the process of the mounting plate 201 approaching, the staff starts the two electric push rods 205 to extend. When the electric push rods 205 are extended, the two movable plates 202 are driven to retract toward the center through the two adjustment bars 207, so that the four movable plates 202 on the top surface of the operating table 1 push the workpiece to move toward the center of the top surface of the operating table 1. The four movable plates 202 are limited in four directions of the workpiece, and the angle between the movable plates 202 can be adjusted according to the size of the workpiece under the action of the electric push rods 205, thereby realizing the positioning of workpieces of different sizes, facilitating subsequent cutting processing, and improving the workpiece cutting efficiency.

[0023] In the embodiment, the bottom surfaces of the movable plates 202 located at the upper left and lower right are each provided with a first notch 3, and the top surfaces of the movable plates 202 located at the lower left and upper right are each provided with a second notch 301. When the two mounting plates 201 are close to each other, the four movable plates 202 are crossed in pairs through the first notch 3 and the second notch 301, so that the movable plates 202 will not interfere with each other during movement and positioning, thereby ensuring the operation of the device.

[0024] In the embodiment, a mounting bracket 4 is fixed to the top surface of the operating table 1, a cylinder 401 is fixed to the top surface of the mounting bracket 4, a cutting device body 402 is arranged inside the mounting bracket 4, and the telescopic end of the cylinder 401 passes through the top surface of the mounting bracket 4 and is fixed to the top surface of the cutting device body 402. When the workpiece is positioned by the movable plate 202, the staff can start the cylinder 401 to drive the cutting device body 402 to cut the workpiece.

[0025] In the embodiment, a center groove 5 is provided on the top surface of the operating table 1, and the center groove 5 is connected to the mounting groove 2. When placing a workpiece, the staff can place the workpiece above the center groove 5 to pre-position the workpiece, thereby improving the workpiece positioning efficiency.

[0026] In the embodiment, a rubber pad 501 is fixed to one side of the movable plate 202. The rubber pad 501 is a prior art. The rubber pad 501 can increase the friction between the workpiece and the movable plate 202, so that the movable plate 202 is more stable when pushing the workpiece.

[0027] Working principle: During use, the staff places the workpiece on the top of the central groove 5, pre-positions the workpiece, and then starts the drive motor to drive the bidirectional screw rod 204 to rotate. The rotation of the bidirectional screw rod 204 causes the two fixed plates 203 to drive the two mounting plates 201 to approach each other. During the process of the mounting plates 201 approaching each other, the staff starts the two electric push rods 205 to extend. When the electric push rods 205 extend, they drive the two movable plates 202 to retract toward the center through the two adjustment bars 207, so that the four movable plates 202 on the top surface of the operating table 1 push the workpiece toward the operating table. 1, the four movable plates 202 are limited in four directions of the workpiece, and the angle between the movable plates 202 can be adjusted according to the size of the workpiece under the action of the electric push rod 205. When the two mounting plates 201 are close to each other, the four movable plates 202 form a cross in pairs through the first notch 3 and the second notch 301, so that the movable plates 202 will not interfere with each other when moving and positioning. After the workpiece is positioned by the movable plate 202, the staff can start the cylinder 401 to drive the cutting device body 402 to cut the workpiece.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
