The design of the cutting fixture aims to improve the processing efficiency, ensure the processing accuracy, reduce the labor intensity, and ensure the safety of the operation process;
[0003] When the existing equipment cuts a product, it is necessary to use a fixture to fix the product. Since the size of the fixing device on the fixture is fixed, it can only fix a single model of product and cannot adapt to the use of multiple models of products, which reduces the cutting efficiency and increases the cutting cost. Summary of the Utility Model
[0004] To solve the above technical problems, the utility model provides an adjustable-length cutting fixture.
[0005] The utility model is realized by the following technical solutions: An adjustable-length cutting fixture includes a base. The upper surface of the base is fixedly connected with a support platform. A ball is rotatably connected to the top of the support platform. The outer wall of the ball is in contact connection with a cover. The cover is rotatably connected to the outer wall of the support platform. A rotating mechanism is arranged on the outer surface of the support platform. The top of the rotating mechanism is fixedly connected with a workbench. One side of the workbench is fixedly connected with a fixing plate. A plurality of fans are arranged inside the fixing plate. A chute is opened on the upper surface of the workbench. A placing table is fixedly connected to the upper surface of the workbench. A positioning block is fixedly connected to the outer wall of the workbench. A screw rod is rotatably connected inside the positioning block. A clamping mechanism is arranged on the outer surface of the screw rod. One end of the screw rod away from the backing plate is fixedly connected with a torsion handle. The screw rod is rotatably connected to the outer wall of the backing plate.
[0006] Through the above technical solutions, the product to be cut is placed on the placing table, and then the screw rod is rotated by rotating the torsion handle, so that the screw rod drives the clamping mechanism, and then the fixing and clamping of the product can be completed.
[0007] As a further improvement of the above solution, the rotating mechanism includes an arc ring. A connecting rod is fixedly connected to the outer wall of the arc ring. The connecting rod is fixedly connected to the outer surface of the support platform. A sliding rod is slidably connected inside the arc ring.
[0008] Through the above technical solutions, under the action of the arc ring, the sliding rod can be fixed in angle while being limited.
[0009] As a further improvement of the above solution, a nut is engaged with the outer surface of the sliding rod, and a fixing block is fixedly connected to the bottom of the sliding rod. One end of the fixing block away from the sliding rod is fixedly connected to the bottom of the clamping cover.
[0010] Through the above technical solution, loosen the nut, then rotate the workbench to a suitable position, and then tighten the nut again to complete the angle fixation of the workbench, improving the efficiency of the cutting process.
[0011] As a further improvement of the above solution, the clamping mechanism includes a backing plate, the bottom of the backing plate is fixedly connected to the upper surface of the workbench, and a clamping table is fixedly connected to the upper surface of the backing plate.
[0012] Through the above technical solution, the clamping table can be kept at a relatively horizontal position height with the product under the action of the backing plate, facilitating clamping alignment.
[0013] As a further improvement of the above solution, two sets of clamping tables are provided. The bottom of the clamping table far from the backing plate is fixedly connected to a sliding plate, the sliding plate is engaged with the outer surface of the screw rod, and the sliding plate is slidably connected to the sliding groove.
[0014] Through the above technical solution, the clamping table far from the backing plate can be limited in the sliding groove, so that it will not tip over during the movement and the horizontal position can not shift.
[0015] As a further improvement of the above solution, a rotating groove is opened at the top of the clamping table, the rotating grooves are symmetrically distributed with the clamping table as the axis, a limiting groove is opened on the inner wall of the rotating groove, and a pressing head is rotatably connected inside the rotating groove.
[0016] Through the above technical solution, when the pressing head touches the outer surface of the product, it will rotate inside the limiting groove and the rotating groove according to the radian of the outer surface of the product, realizing the adaptive adjustment of the clamping angle.
[0017] As a further improvement of the above solution, a clamping plate is fixedly connected to the outer surface of the pressing head, the clamping plate is slidably connected inside the limiting groove, and a pair of rubber heads are fixedly connected to the side of the pressing head away from the clamping table.
[0018] Through the above technical solution, the pressing head can be effectively limited in the rotating groove by the clamping plate and will not fall off. When the pressing head touches the outer surface of the product, it will rotate inside the limiting groove and the rotating groove according to the radian of the outer surface of the product, so that the rubber heads can be pressed against the outer surface of the product. This setting enables the extrusion direction of the rubber heads to be adjusted automatically according to the radian and shape of the outer surface of the product when fixing the product, thereby realizing the effective clamping of the workpiece.
[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0020] In the present utility model, turning the torsion handle drives the screw rod to rotate, causing the sliding plate to move along the outer surface of the screw rod. As a result, the clamping table on the sliding plate moves towards the clamping table on the upper surface of the backing plate. When the pressing head touches the outer surface of the product, it rotates inside the limiting groove and the rotating groove according to the arc of the outer surface of the product. Thus, the rubber head can squeeze against the outer surface of the product. This setting enables the extrusion direction of the rubber head to be adjusted automatically according to the arc and shape of the outer surface of the product when fixing the product, thereby achieving effective clamping of the workpiece and a wider range of applications.
[0021] In the present utility model, loosen the nut, and then turn the workbench to a suitable position. During this process, due to the arranged balls, the rotation between the clamping cover and the support table is smoother and more stable. At the same time, under the action of the arc ring, the sliding rod can be fixed at an angle while being limited. Then, tighten the nut again to complete the angle fixation of the workbench without re-fixing the product, improving the efficiency of the cutting process. BRIEF DESCRIPTION OF THE DRAWINGS

A placing table 10 is fixedly connected to the upper surface of the workbench 6. A positioning block 11 is fixedly connected to the outer wall of the workbench 6. A screw 12 is rotatably connected inside the positioning block 11. A clamping mechanism 13 is arranged on the outer surface of the screw 12. A torsion handle 14 is fixedly connected to the end of the screw 12 away from the backing plate 131. The screw 12 is rotatably connected to the outer wall of the backing plate 131.
[0032] The rotating mechanism 5 includes an arc ring 501. A connecting rod 502 is fixedly connected to the outer wall of the arc ring 501. The connecting rod 502 is fixedly connected to the outer surface of the support table 2. A sliding rod 503 is slidably connected inside the arc ring 501.
[0033] A nut 504 is engaged with the outer surface of the sliding rod 503. A fixing block 505 is fixedly connected to the bottom of the sliding rod 503. The end of the fixing block 505 away from the sliding rod 503 is fixedly connected to the bottom of the cover 4.
[0034] The clamping mechanism 13 includes a backing plate 131. The bottom of the backing plate 131 is fixedly connected to the upper surface of the workbench 6. A clamping table 132 is fixedly connected to the upper surface of the backing plate 131.
[0035] There are two groups of clamping tables 132. Among them, the bottom of the clamping table 132 away from the backing plate 131 is fixedly connected to a sliding plate 138. The sliding plate 138 is meshed with the outer surface of the screw 12, and the sliding plate 138 is slidably connected to the chute 9.
[0036] A rotating groove 133 is opened on the top of the clamping table 132. The rotating grooves 133 are symmetrically distributed with the clamping table 132 as the axis. A limiting groove 134 is opened on the inner wall of the rotating groove 133. A pressing head 135 is rotatably connected inside the rotating groove 133.

[0038] In the embodiment of the present application, the implementation principle of an adjustable-length cutting jig is as follows: First, place the product to be cut on the placement table 10. Then, rotate the turning handle 14 to drive the screw rod 12 to rotate, so that the sliding plate 138 moves along the outer surface of the screw rod 12. As a result, the clamping table 132 on the sliding plate 138 moves towards the clamping table 132 on the upper surface of the backing plate 131. When the pressing head 135 touches the outer surface of the product, it will rotate inside the limiting groove 134 and the rotating groove 133 according to the curvature of the outer surface of the product. Thus, the rubber head 137 can be pressed against the outer surface of the product. This setting enables the extrusion direction of the rubber head 137 to be adjusted automatically according to the curvature and shape of the outer surface of the product when fixing the product, thereby realizing effective clamping of the workpiece and having a wider scope of application. When some products need to be cut at multiple angles, there is no need to re-fix the product. At this time, only need to loosen the nut 504, then rotate the workbench 6 to the appropriate position, and then tighten the nut 504 again to complete the angle fixation of the workbench 6, improving the efficiency of the cutting process. During this process, due to the provided balls 3, the rotation between the cover 4 and the support table 2 is smoother and more stable. At the same time, under the action of the arc ring 501, the sliding rod 503 can be limited while the angle is fixed.
[0039] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
