[0002] Round steel cutting machine refers to a cutting device used for round or quasi-round alloy steel or stainless steel parts. It has the characteristics of fast cutting speed and uniform cutting length, and is widely used in the rough processing stage of mechanical processing.

[0003] The prior art has a patent number of CN215546863U for a fixing device for a round steel cutting machine. Although it uses a threaded rod conveying method to stably convey the round steel, it is provided with a plurality of round steel stabilizing structures fixed on the support frame, so that the movable component can only be conveyed between two round steel stabilizing structures. Therefore, when conveying a section of round steel, it can only convey the distance between the two round steel stabilizing structures, which is inconvenient for production. Utility Model Content

[0004] Based on this, it is necessary to provide an automatic feeding and fixing device for a round steel cutting machine in response to the above technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an automatic feeding and fixing device for a round steel cutting machine, comprising a frame and a cutting machine, wherein a threaded rod is threadedly connected to the frame, and a plurality of clamping mechanisms are slidably clamped on the frame, a driving cylinder is slidably clamped on the frame, the driving cylinder is threadedly connected to the threaded rod, and two abutting blocks are slidably and sealedly connected to the driving cylinder, and the two abutting blocks are connected by a spring, and the top of the driving cylinder is slidably and sealedly connected to a pushing block, an abutting groove is provided at the bottom of the clamping mechanism, and the pushing block is matched with the abutting groove, a switching groove is provided on the frame, and a limit strip is installed on the frame, and the limit strip is located above the switching groove, and a limit mechanism for limiting the movement of the driving cylinder is installed on the frame, and the limit rod is slidably clamped on the clamping mechanism, and the limit rod is matched with the pushing block.

[0010] Preferably, a plurality of abutment wheels are rotatably mounted on the abutment block, and the abutment wheels abut against the inner wall of the frame.

[0011] Preferably, a friction block is installed on the top end of the limiting rod.

[0012] Preferably, the limiting block is provided with a chamfer.

[0013] Compared with the existing technology, this technical solution has at least one of the following beneficial effects:

[0014] The frame squeezes the abutment block, so that the push block is squeezed out and abuts against the abutment groove, driving the clamping mechanism to move.

DETAILED DESCRIPTION

[0021] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] See also Figures 1 to 4 The embodiment of the present application provides an automatic feeding and fixing device for a round steel cutting machine, comprising a frame 1 and a cutting machine 2. A threaded rod 3 is threadedly connected to the frame 1. Several clamping mechanisms are slidably engaged with the frame 1. A drive cylinder 4 is slidably engaged with the frame 1. The drive cylinder 4 can be a hydraulic cylinder or a pneumatic cylinder. The drive cylinder 4 is threadedly engaged with the threaded rod 3. Two abutting blocks 5 are slidably and sealedly connected to the drive cylinder 4. The two abutting blocks 5 are connected by a spring 6. A push block 7 is slidably and sealedly connected to the top of the drive cylinder 4. An abutting groove 8 is provided at the bottom of the clamping mechanism. The push block 7 cooperates with the abutting groove 8. A switching groove 9 is provided on the frame 1. A limit bar 10 is installed on the frame 1. The limit bar 10 is located above the switching groove 9. A limit mechanism for limiting the movement of the drive cylinder 4 is installed on the frame 1. A limit rod 11 is slidably engaged with the clamping mechanism. The limit rod 11 cooperates with the push block 7. The drive device for driving the threaded rod 3 and the limit mechanism should be connected via a signal processor so that the two can cooperate to replace the driven clamping mechanism.

[0023] When the clamping mechanism driven by the pushing block 7 passes the switching groove 9, the spring 6 pushes the abutting block 5 to extend, so that the pushing block 7 is lowered due to the change in the internal pressure of the driving cylinder 4, and no longer pushes the clamping mechanism, and then the threaded rod 3 continues to drive the driving cylinder. When the clamping mechanism is not driven by the driving cylinder 4 and pushed, there is a certain friction between it and the round steel, but the round steel can slide out from it due to the limiting effect of the limiting mechanism or the limiting bar 10 on the clamping mechanism.

[0024] In some embodiments, in order to facilitate the clamping and conveying of round steel, a clamping mechanism is provided that further includes a movable seat 12 and an articulated block 13. The movable seat 12 is slidably clamped on the frame 1. The articulated block 13 is hinged to the top of the movable seat 12. A plurality of screws 14 are threadedly connected to the top of the articulated block 13. The screws 14 are threadedly connected to the movable seat 12. The movable seat 12 and the articulated block 13 form a circular groove, and the top of the limiting rod 11 is located at the bottom of the circular groove. Thus, after the round steel is placed on the movable seat 12, the articulated block 13 is connected to the movable seat 12 by the screw 14, so that the round steel can be limited to a certain position. When the limiting rod 11 is squeezed and moved upward, the round steel in the circular groove is squeezed and rubbed, thereby conveying the round steel.

[0025] In some embodiments, to facilitate limiting the position of the clamping mechanism, a limiting mechanism is provided, including a limiting block 15 and a linear actuator 16. The linear actuator 16 can be an electric cylinder. The limiting block 15 is slidably engaged with the frame 1. The linear actuator 16 is mounted on the frame 1, and the output end of the linear actuator 16 is connected to the limiting block 15. The linear actuator 16 controls whether the limiting block 15 extends, thereby limiting the position of the clamping mechanism.

[0026] In some embodiments, in order to facilitate driving the driving cylinder 4 , a plurality of threaded blocks 17 are provided on the frame 1 to be slidably engaged. The driving cylinder 4 is mounted on the threaded blocks 17 , and the threaded blocks 17 are threadedly connected to the threaded rod 3 .

[0027] In some embodiments, in order to facilitate driving the threaded rod 3 , a rotation drive device 18 is installed on the frame 1 . The rotation drive device 18 may be a servo motor, and the output end of the rotation drive device 18 is transmission-connected to the threaded rod 3 .

[0028] In some embodiments, in order to reduce the friction between the abutment block 5 and the inner wall of the frame 1 , a plurality of abutment wheels 19 are rotatably mounted on the abutment block 5 , and the abutment wheels 19 abut against the inner wall of the frame 1 .

[0029] In some embodiments, in order to increase the friction between the top of the limiting rod 11 and the round steel, a friction block 20 is installed on the top of the limiting rod 11.

[0030] In some embodiments, in order to facilitate the reset of the clamping mechanism to the appropriate position, a chamfer is provided on the limit block 15. The chamfer guides the clamping mechanism to reset, avoiding damage caused by direct collision between the clamping mechanism and the round steel due to the vibration during conveying.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
