The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This utility model embodiment provides an automatic clamping device for a steel claw straightening machine, such as... Figure 1-6 As shown, the automatic clamping device of the steel claw straightening machine includes: a hanging chain track 2 set on a fixed beam 1 for conveying the steel claw; a support frame 3 set on the hanging chain track 2, and a guide device 4 mounted on the support frame 3; a clamping cylinder 5 mounted on the guide device 4, and a positioning handle 6 for clamping and positioning the steel claw is set on the output shaft of the clamping cylinder 5; and a positioning mechanism mounted on the guide device 4 for positioning the steel claw.

[0025] In this embodiment, a controller is first installed on one side of the device. The controller can control the entire device. The working principle of the controller is existing technology and will not be described in detail here. When processing the steel claw, the main beam 1 is first fixed in the corresponding position in the workshop. This installation facilitates subsequent maintenance. The steel claw can be transported by the chain track 2 to the corresponding position of the steel claw straightening machine. During the transport of the steel claw, the guide device 4 first contacts the steel claw to reduce the left and right sway of the steel claw. At the same time, the controller activates the positioning mechanism to clamp and position the guide rod on the steel claw, thereby initially positioning the steel claw and keeping it stable. The positioning handle 6 is positioned so that it can stably clamp and position the steel claw. Once the designated position is reached, the hanging chain track 2 stops, the clamping cylinder 5 operates, and the positioning handle 6 moves to clamp the guide rod on the steel claw. This allows the steel claw to be accurately aligned with the high-frequency coil on the straightening machine for straightening. After straightening, the clamping cylinder 5 releases, allowing the positioning handle 6 to disengage from the steel claw. At the same time, the controller also activates the positioning mechanism to disengage from the steel claw. Then, the hanging chain track 2 transports the straightened steel claw. Through this entire device, the steel claw can be stably clamped and positioned. It is easy to maintain, reduces manual maintenance costs, and can achieve accurate automatic positioning without the need for manual positions.

[0026] In a further preferred embodiment of the present invention, the positioning mechanism includes: a mounting plate 7 fixedly mounted on the guide device 4; a telescopic rod 8 fixedly mounted on the mounting plate 7, with a mounting shell 10 fixedly mounted on the output shaft of the telescopic rod 8; a positioning frame 9 disposed on the mounting shell 10 for clamping and positioning the steel claw; and a rotation mechanism assembled on the mounting shell 10 and the positioning frame 9 for rotating and adjusting the position of the positioning frame 9.

[0027] In this embodiment, when processing the steel claw, after the guide device 4 makes initial contact with the steel claw, the controller activates the telescopic rod 8 to move the positioning frame 9 to a certain extent. Then, the controller activates the rotating mechanism to rotate the positioning frame 9 to one side of the steel claw guide rod. Then, the controller activates the telescopic rod 8 again to move the positioning frame 9, so that the positioning frame 9 contacts the steel claw guide rod, thereby initially positioning the steel claw guide rod and keeping the steel claw stable. This facilitates the subsequent stable clamping and positioning of the steel claw by the positioning handrail 6, improving the stability of the subsequent positioning of the steel claw guide rod by the positioning handrail 6.

[0028] In a further preferred embodiment of the present invention, the rotating mechanism includes: a motor 11 fixedly mounted on the mounting housing 10; and a mounting shaft 12 rotatably mounted on the mounting housing 10, one end of the mounting shaft 12 being fixedly connected to the output shaft of the motor 11, and the other end of the mounting shaft 12 being connected to the positioning frame 9.

[0029] In this embodiment, when using the rotating mechanism, the controller starts the motor 11 to drive the mounting shaft 12 to rotate, thereby driving the positioning frame 9 to rotate and adjusting the positioning frame 9 to one side of the steel claw guide rod, so that the positioning frame 9 can clamp and position the steel claw guide rod.

[0030] In a further preferred embodiment of the present invention, the positioning frame 9 includes a connecting plate 901 and a clamping plate 902. The connecting plate 901 is fixedly mounted on the mounting shaft 12, and the clamping plate 902 is disposed on one side of the connecting plate 901. A buffer mechanism is provided on the connecting plate 901 and the clamping plate 902.

[0031] In this embodiment, when the telescopic rod 8 moves the positioning frame 9 and the positioning frame 9 contacts the steel claw guide rod, the clamping plate 902 will contact the steel claw guide rod. At the same time, under the action of the buffer mechanism, the clamping plate 902 can have a certain buffering effect, thereby avoiding excessive compression of the steel claw and thus protecting the steel claw.

[0032] In a further preferred embodiment of the present invention, the buffer mechanism includes: a placement shell 15 fixedly installed on the connecting plate 901, wherein a spring 16 is provided inside the placement shell 15; and a connecting frame 17 slidably installed on the placement shell 15, wherein the connecting frame 17 is fixedly connected to the clamping plate 902.

[0033] In this embodiment, when the clamping plate 902 comes into contact with the steel claw guide rod, the clamping plate 902 will move the connecting frame 17 within the placement shell 15 under the pressure of the clamping plate 902, thus compressing the spring 16. Under the action of the spring 16, the clamping plate 902 has a certain buffering effect, thereby avoiding excessive compression of the steel claw and thus protecting the steel claw.

[0034] In a further preferred embodiment of the present invention, a telescopic guide rod is provided inside the placement shell 15, and the telescopic guide rod is located inside the spring 16.

[0035] In this embodiment, the stability of spring 16 during deformation can be improved by using a telescopic guide rod.

[0036] In a further preferred embodiment of the present invention, a sliding groove 13 is provided on the mounting shell 10. The sliding groove 13 is arranged in a ring shape. A plurality of sliders 14 are fixedly installed on the connecting plate 901, and the plurality of sliders 14 are slidably connected to the sliding groove 13.

[0037] In this embodiment, when the motor 11 drives the mounting shaft 12 to rotate, thereby driving the positioning frame 9 to rotate, the positioning frame 9 will drive the slider 14 to rotate in the slide groove 13, thereby improving the stability of the positioning frame 9 when it rotates.

[0038] In summary, compared with related technologies, the entire device can stably clamp and position the steel claw, is easy to maintain, reduces manual maintenance costs, and can achieve precise automatic positioning without the need for manual positions.

[0039] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
