Description

Technical Field

[0002] The cutting mechanism for a pipe, in the application of automated equipment, generally needs to adjust the storage position of the cutting mechanism in accordance with the cutting position of the pipe.

[0003] In the conventional movement and positioning method of the cutting mechanism, a cylinder or a star handle fixing method is generally used, as follows:

[0004] First, if the cylinder is used to drive the cutting mechanism to move as a whole to adjust the storage position, the cylinder drive method needs to be used in conjunction with a control system / device that drives the cylinder to move. Although the cylinder drive movement has high accuracy, the application cost is high;

[0005] Second, if a star-shaped handle is used in combination with a guide rail installed under the cutting mechanism to realize the mobile positioning of the cutting mechanism, the star-shaped handle locks the cutting mechanism in place by rotating it in combination with a fixed component (such as a table).

[0039] In order to better illustrate the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0040] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present application.

[0041] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the embodiments of the present application. The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0042] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and do not have to be used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0043] In addition, in the description of this application, unless otherwise specified, "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0044] In the conventional movement and positioning method of the cutting mechanism, a cylinder or a star handle fixing method is generally used, as follows:

[0045] First, if the cylinder is used to drive the cutting mechanism to move as a whole to adjust the storage position, the cylinder drive method needs to be used in conjunction with a control system / device that drives the cylinder to move. Although the cylinder drive movement has high accuracy, the application cost is high;

[0046] Second, if a star-shaped handle is used in combination with a guide rail installed under the cutting mechanism to realize the mobile positioning of the cutting mechanism, the star-shaped handle locks the cutting mechanism in place by rotating it in combination with a fixed component (such as a table). It is understandable that the star-shaped handle also unlocks the cutting mechanism by rotating it. Since it is difficult to control the degree of rotation when the star handle is rotated, the cutting mechanism is difficult to unlock when it is positioned too tightly and the cutting mechanism vibrates when it is loosely positioned.

[0047] From the above, it can be seen that the method of using a cylinder to drive the overall movement and positioning of the cutting mechanism has a good application in the movement accuracy of the cutting mechanism when combined with the use of a control system / device, but the cost is relatively high; the method of using a star-shaped handle combined with a guide rail to move and position the cutting mechanism is low in cost and simple to operate, but it is difficult to judge whether the cutting mechanism is stably positioned.

[0048] Therefore, the technical problem actually solved by the present application is to provide a device for moving and positioning a cutting mechanism, which has the effect of ensuring the movement accuracy of the cutting mechanism and facilitating operation under cost control.

[0049] As an illustrative example of this application, Figure 1 to Figure 2 As shown, a device for moving and positioning a cutting mechanism is provided, comprising:

[0050] A first moving mechanism 1, the first moving mechanism 1 comprises a slide rail 11 and a plate 12 disposed on the slide rail 11 and capable of moving on the slide rail 11, and a cutting mechanism 10 is installed on the plate 12;

[0051] A positioning mechanism 3, wherein the positioning mechanism 3 is mounted on the flat plate 12, and a lever 31 capable of moving up and down is disposed in the positioning mechanism 3;

[0052] The second moving mechanism 2 is arranged below the lever 31. After the lever 31 moves downward, the lower end of the lever 31 is connected to the second moving mechanism 2 so that the second moving mechanism 2 can drive the plate 12 and the cutting mechanism 10 to move as a whole through the positioning mechanism 3.

[0053] The device for moving and positioning the cutting mechanism in this embodiment includes a first moving mechanism 1, a positioning mechanism 3 and a second moving mechanism 2. The first moving mechanism 1 includes a slide rail 11 and a plate 12 arranged on the slide rail 11 and capable of being mounted on the slide rail 11. The cutting mechanism 10 is installed on the plate 12. By setting the positioning mechanism 3, a lever 31 capable of moving up and down is arranged in the positioning mechanism 3. The lever 31 is moved up and down to cooperate with the second moving mechanism 2 to lock and unlock the cutting mechanism 10 arranged on the first moving mechanism 1, thereby simplifying the movement and positioning application of the cutting mechanism 10. At the same time, with the first moving mechanism 1 and the positioning mechanism 3 as a unified whole, the second mechanism can be used to make secondary adjustments to the movement of the first moving mechanism 1 and the positioning structure to ensure the accurate movement position of the cutting mechanism 10.

[0054] In this embodiment, specifically, Figure 1 and Figure 2 As shown, the second moving mechanism 2 includes:

[0055] A screw rod 21, one end of which is provided with a hand wheel 22, and the screw rod 21 is driven to rotate by manually operating the hand wheel 22;

[0056] The lower end of the lever 31 is provided with an internal thread matching the external thread shape on the screw rod 21;

[0057] Among them, after the lever 31 moves downward, the lower end of the lever 31 and the screw rod 21 are engaged with each other through the external thread and the internal thread to position the position of the plate 12, thereby limiting the movement of the plate 12 in the horizontal direction where the second moving mechanism 2 is located; by rotating the hand wheel 22 to drive the screw rod 21 to rotate, the internal thread at the lower end of the lever 31 and the external thread on the screw rod 21 rotate in opposite directions to drive the plate 12 to move on the slide rail 11.

[0058] The above combined with the transmission characteristics of the screw rod 21 enables the second moving mechanism 2 to perform secondary position adjustment on the cutting mechanism 10, so that the moving position of the cutting mechanism 10 is accurate.

[0059] Preferably, the screw rod 21 is a trapezoidal screw rod.

[0060] Furthermore, the second moving mechanism 2 also includes:

[0061] The movable fixing seat 23, the screw rod 21 is arranged through the movable fixing seat 23 and movably installed, and the installation position of the screw rod 21 is determined by the movable fixing seat 23. The setting direction of the screw rod 21 in this embodiment is consistent with the setting direction of the slide rail 11, that is, Figure 1 As shown in;

[0062] A baffle 24, wherein the baffle 24 is disposed at one end of the screw rod 21, and the baffle 24 is used to abut against the baffle 24 when the lever 31 moves relative to the screw rod 21 and the lever 31 moves to the position of the baffle 24;

[0063] Similarly, when the lever 31 and the screw rod 21 move relative to each other, the lever 31 moves to the position of the movable fixing seat 23 and can abut against the movable fixing seat 23;

[0064] The spacing distance between the movable fixing seat 23 and the blocking piece 24 is the movable range of the shifting rod 31 on the screw rod 21 .

[0065] In this embodiment, if Figure 2 As shown, the positioning mechanism 3 also includes:

[0066] A positioning seat 32, the positioning seat 32 passes through the flat plate 12 and is arranged on the flat plate 12, the positioning seat 32 has a mounting cavity, a lever 31 is arranged in the mounting cavity, and the mounting cavity is used to limit the position of the lever 31, so that the lever 31 can only move up and down in the mounting cavity;

[0067] A clamping nut 33, wherein the clamping nut 33 is threadedly connected to the upper end of the positioning seat 32, and the clamping nut 33 is located above the plate 12, and the position of the positioning seat 32 is fixed by the clamping nut 33;

[0068] The handle 34 is rotatably mounted on the upper end of the lever 31. The lever 31 is driven to move up and down by rotating the handle 34. When the handle 34 is moved downward, the middle portion of the handle 34 abuts against the clamping nut 33, thereby lifting the connection end between the handle 34 and the lever 31 upward, thereby driving the lever 31 to move upward. Then, the handle 34 is swung upward, and the handle 34 is separated from the clamping nut 33, thereby causing the connection end between the handle 34 and the lever 31 to move downward, thereby driving the lever 31 to move downward.

[0069] In addition, a spring 35 is sleeved on the lever 31;

[0070] A step portion 321 is provided at the middle of the lever 31 , the lower end of the spring 35 abuts against the step portion 321 , and the upper end of the spring 35 abuts against the clamping nut 33 ;

[0071] When the handle 34 is pushed upward or pushed downward, the spring 35 is always in a compressed state.

[0072] Since the top end of the lever 31 is restrained by the handle 34 , when the spring 35 is always in a compressed state, the lever 31 is always pushed downward, so that when the lever 31 moves downward, the lever 31 can be in close contact with the screw rod 21 .

[0073] As two aspects of this application, Figure 3 As shown, a cutting device is provided, comprising:

[0074] A traction mechanism 20, wherein the traction mechanism 20 is used for traction of materials;

[0075] A cutting mechanism 10, wherein the cutting mechanism 10 is disposed close to the traction mechanism 20, and the cutting mechanism 10 is used to receive and cut the material;

[0076] As mentioned above, the device 30 for moving and positioning the cutting mechanism is installed below the cutting mechanism 10 , and the device 30 is used to adjust the spacing distance between the cutting mechanism 10 and the traction mechanism 20 .

[0077] Since the cutting device applies the device 30 for moving and positioning the cutting mechanism as described above, the cutting device has all the beneficial effects of the device, which are not described one by one here.

[0078] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
