Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a wire cutting clamp used for a plurality of cylindrical materials. Background Art

[0002] When performing wire cutting on materials, a clamp is needed to fix the materials and determine the processing position for easy processing. Currently, most of the clamps on the market have a relatively simple structure and a single clamping method, often using four mutually perpendicular directions for clamping. In addition, when performing wire cutting on multiple cylindrical materials, existing wire cutting clamps often use ropes to bundle the materials, and then clamp them through four mutually perpendicular clamps. This clamping method is unstable and often causes the materials to shift, resulting in uneven cutting surfaces, low precision, and even missed or wrong cutting, which seriously affects the quality of the finished product.

[0003] Therefore, in view of the above problems, a wire cutting fixture for multiple cylindrical materials with batch limiting effect and improved cutting accuracy is now developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices that have poor batch limiting fixing effect, materials often offset, resulting in uneven material cutting surface, low precision, and even missed cutting or wrong cutting, which seriously affects the quality of the finished product, the utility model provides a wire cutting fixture for multiple cylindrical materials with batch limiting effect and improved cutting accuracy.

[0005] The technical solution of the utility model is: a wire cutting fixture for multiple cylindrical materials, including a mounting frame, there are two mounting frames, the inner sides of the mounting frames are connected with cover plates by bolts, the interior of the mounting frames are rotatably connected with turntables, six first clamping members are slidably connected to the turntable on the right side, the first clamping members on the lower side are slidably connected to the cover plate on the right side, six second clamping members are also slidably connected to the turntable on the left side, the second clamping members on the lower side are slidably connected to the cover plate on the left side, the inner sides of the second clamping members are rotatably connected with clamping members, the mounting frames are connected with hydraulic cylinders, and the telescopic ends of the hydraulic cylinders are respectively connected to the adjacent first clamping members and the second clamping members on the lower side.

[0006] More preferably, the adjustment mechanism includes a base, the bases are installed between the lower sides of the installation frames, the installation frames are slidably connected to the bases, the outer sides of the bases are connected to drive motors, the middle parts of the bases are rotatably connected to first screw rods, the first screw rods are through-connected to the adjacent bases, the installation frames are threadedly connected to the adjacent first screw rods, and a pulley assembly is connected between the output shaft of the drive motor and the adjacent first screw rods.

[0009] More preferably, the first clamping members are in contact with each other, and the second clamping members are also in contact with each other.

[0010] More preferably, the pulley assembly includes a pulley and a transmission belt.

[0011] By adopting the above technical solution, compared with the prior art, the utility model has the following advantages:

[0012] 1.

DETAILED DESCRIPTION

[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. Example 1

[0021] A wire cutting fixture for multiple cylindrical materials, such as Figure 1-Figure 3 As shown, it includes an installation frame 1, and there are two installation frames 1. The inner sides of the installation frames 1 are connected with cover plates 2 by bolts. The interior of the installation frames 1 is rotatably connected with turntables 4. Six first clamping members 3 for clamping and fixing the right part of the cylindrical material are slidably connected to the turntable 4 on the right side. The first clamping members 3 on the lower side are slidably connected to the cover plate 2 on the right side. Six second clamping members 6 for clamping and fixing the left part of the cylindrical material are also slidably connected to the turntable 4 on the left side. The second clamping members 6 on the lower side are slidably connected to the cover plate 2 on the left side. The inner sides of the second clamping members 6 are rotatably connected with clamping members 7 for pressing down and fixing the cylindrical material. Four arc grooves are opened on the clamping members 7. The installation frames 1 are connected with hydraulic cylinders 5. The telescopic ends of the hydraulic cylinders 5 are all set to face backward. The telescopic ends of the hydraulic cylinders 5 are respectively connected to the adjacent first clamping members 3 and the second clamping members 6 on the lower side. The first clamping members 3 fit each other, and the second clamping members 6 also fit each other.

[0022] like Figure 1 and Figure 4 As shown, the adjustment mechanism 8 includes a base 81, and the bases 81 are installed between the lower sides of the mounting frames 1. The mounting frames 1 are slidably connected to the base 81. The outer sides of the bases 81 are connected to drive motors 82, and the output shafts of the drive motors 82 are arranged oppositely. The middle positions of the bases 81 are rotatably connected to first screw rods 84, and the first screw rods 84 are through-connected to the adjacent bases 81. The mounting frames 1 are threadedly connected to the adjacent first screw rods 84, and a pulley assembly 83 is connected between the output shaft of the drive motor 82 and the adjacent first screw rods 84. The pulley assembly 83 includes a pulley and a transmission belt.

[0023] It should be noted that when the material is cut linearly, a clamp is required to fix the material and determine the processing position for easy processing. At this time, the present device can be used to clamp the material, especially for cylindrical materials, with a more stable clamping effect. First, the telescopic ends of the hydraulic cylinder 5 are controlled to move forward and contract, so that the first clamping member 3 and the second clamping member 6 can both move and unfold to form a material movement path. Then the material passes through the second clamping member 6 and the first clamping member 3 in sequence. After completion, the output shaft of the drive motor 82 is controlled to rotate according to the specific length of the material, so that the first screw rod 84 rotates to drive the mounting frame 1 to adjust the position, so that the spacing between the mounting frames 1 can be adapted to the length of the material by a certain amount to avoid the material exceeding the distance too much to affect the stability. After the processing is completed, the telescopic ends of the hydraulic cylinder 5 are controlled to move backward and reset, so that the first clamping member 3 and the second clamping member 6 can both move inward and contract, thereby clamping and fixing the material. At the same time, the pressing member 7 on the second clamping member 6 can fit the outer surface of the cylindrical material, making the cylindrical material more stable and avoiding material displacement, so that the cutting process can be more precise. Example 2

[0024] On the basis of Example 1, Figure 1 and Figure 5 As shown, it also includes a positioning mechanism 9, which includes a fixing frame 91. The upper and lower right sides of the left cover plate 2 are connected to the fixing frame 91. The fixing frame 91 and the cover plate 2 are a detachable connection structure. The right side of the fixing frame 91 is slidably connected with a positioning plate 92 for guiding and positioning the cutting equipment. The right side of the fixing frame 91 is rotatably connected with two second screw rods 93, and the second screw rods 93 are threadedly connected to the adjacent positioning plates 92.

[0025] It should be noted that in order to further improve the stability during the cutting process, the cutting position is adjusted by rotating the second screw 93 to move the positioning plate 92, and the cutting device is continuously moved and guided during the cutting process so that the material cut can remain flat.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
