Description

Technical Field

[0001] This utility model relates to the field of sawing machines, and in particular to a sawing machine clamp. Background Technology

[0002] In industries such as metal processing, construction, and pipe installation, sawing machines are commonly used for cutting cylindrical workpieces such as round bars and pipes. To ensure the accuracy, safety, and efficiency of the cutting process, the round material needs to be securely clamped before sawing. Therefore, specialized clamps used with the sawing machine are crucial.

[0003] Among existing round material clamping fixtures for sawing machines, V-groove clamping blocks with pressing devices are a common structure. This type of fixture typically includes one or a pair of fixed clamping blocks with V-grooves. The round material is pressed into the V-groove by a movable pressure plate or pressure arm on top. The V-groove design provides stable three-point contact, which helps prevent the round material from rolling.

[0004] However, this type of fixture reveals a significant and long-standing core problem in use: its structure is difficult to adapt conveniently and efficiently to the clamping needs of round materials with different diameters. A single-specification V-groove clamping block can usually only effectively clamp round materials within a specific diameter range. When the workpiece diameter varies significantly, operators often need to manually replace the entire clamping block module or add a special adapter bushing. This is not only cumbersome and time-consuming, but also reduces overall processing efficiency. Therefore, a sawing fixture is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sawing fixture, which aims to improve the problem that existing sawing fixtures are not easy to adjust according to the diameter of round materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sawing fixture includes a fixed plate and a round piece of material. A mounting base is fixedly connected to the right side of the fixed plate, and a connecting plate is fixedly connected to the right side of the mounting base. A drive assembly is mounted on the left side of the connecting plate. A slide rod is fixedly connected to the right side of the connecting plate, and a movable plate is slidably connected to the outer periphery of the slide rod. Longitudinal rods are fixedly connected to the sides of the connecting plate and the movable plate facing each other. Electric push rods are fixedly connected to the front and rear sides of the longitudinal rods. Crossbars are fixedly connected to the output ends of the two electric push rods. Clamping blocks are fixedly connected to the sides of the two crossbars facing each other. The round piece of material is located between the two sets of clamping blocks.

[0008] The drive assembly includes a servo motor, which is fixedly connected to the left side of the connecting plate. A lead screw is fixedly connected to the output end of the connecting plate, and the movable plate is threadedly connected to the outer periphery of the lead screw.

[0009] As a further description of the above technical solution:

[0010] The outer periphery of the clamping block is covered with an anti-slip pad, a round rod is fixedly connected to the middle of the clamping block, a locking rod is slidably connected to the middle of the clamping block, the other end of the locking rod passes through the anti-slip pad and is fixedly connected to a locking plate, a pull plate is fixedly connected to the outside of the locking plate, and an elastic component is installed between the round rod and the pull plate.

[0011] As a further description of the above technical solution:

[0012] The elastic component includes a slider that is slidably connected to the outer periphery of the round rod. A compression spring is sleeved on the outer periphery of the round rod. A connecting rod is rotatably connected to the middle of the slider, and the other end of the connecting rod is rotatably connected to the side of the pull plate near the clamping block.

[0013] As a further description of the above technical solution:

[0014] Both the connecting plate and the movable plate have a limiting groove in the middle. Each of the two sets of clamping blocks is fixedly connected to a limiting block on one side opposite to the other. The limiting block is slidably connected to the middle of the limiting groove.

[0015] As a further description of the above technical solution:

[0016] The lead screw and the slide rod are respectively fixedly connected to a stop block one and a stop block two at the ends away from the connecting plate;

[0017] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:

[0020] The clamping block has a locking hole in the middle, and the locking rod is slidably connected to the middle of the locking hole;

[0021] As a further description of the above technical solution:

[0022] The compression spring is located on the side of the slider near the inner wall of the clamping block.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the upper and lower distance of the clamping block is first adjusted by the fixed electric push rod, so that the clamping block can fix round materials of different diameters with the cooperation of the electric push rod and the servo motor.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3This utility model provides an embodiment of a sawing fixture, comprising a fixed plate 1 and a round piece 6. A mounting base 2 is fixedly connected to the right side of the fixed plate 1, and a connecting plate 3 is fixedly connected to the right side of the mounting base 2. A drive assembly is installed on the left side of the connecting plate 3. A slide rod 10 is fixedly connected to the right side of the connecting plate 3, and a movable plate 4 is slidably connected to the outer periphery of the slide rod 10. A longitudinal rod 16 is fixedly connected to the side of the connecting plate 3 facing the movable plate 4. Electric push rods 17 are fixedly connected to the front and rear sides of the longitudinal rods 16. A cross rod 12 is fixedly connected to the output end of each of the two electric push rods 17. A clamping block 5 is fixedly connected to the side of each of the two cross rods 12 facing each other. The round piece 6 is located between the two sets of clamping blocks 5. The drive assembly includes a servo motor 7, which is fixedly connected to the left side of the connecting plate 3. A lead screw 8 is fixedly connected to the output end of the connecting plate 3. The movable plate 4 is threadedly connected to the outer periphery of the lead screw 8. A compression spring 23 is located on the side of the slider 24 near the inner wall of the clamping block 5. First, the servo motor 7 drives the lead screw 8 to rotate. Under the limiting action of the slide bar 10, the movable plate 4 can move one set of clamping blocks 5 closer to another set of clamping blocks 5, thereby fixing the round material 6 between the two sets of clamping blocks 5. Under the action of the four inclined sides, the round material 6 is fixed at multiple points, improving the fixing stability. At the same time, before fixing the round material 6, the electric push rod 17 is driven to push the crossbar 12, so that the vertical distance between the two clamping blocks 5 in the same set can be adjusted. Then, the servo motor 7 drives the movable plate 4 to move, so that the two sets of clamping blocks 5 can fix round materials 6 of different diameters, thereby improving the applicability of the fixture and thus improving the processing efficiency of round materials 6 of different diameters.

[0035] Reference Figure 2 and Figure 3 Both the connecting plate 3 and the movable plate 4 have limiting grooves 18 in their middle sections. Each of the two sets of clamping blocks 5 has a limiting block 19 fixedly connected to one side of its opposite side. The limiting block 19 is slidably connected to the middle of the limiting groove 18. The limiting block 19 and the limiting groove 18 improve the stability of the two sets of clamping blocks 5 between the connecting plate 3 and the movable plate 4.

[0036] Reference Figure 1 and Figure 2 The ends of the lead screw 8 and slide rod 10 furthest from the connecting plate 3 are respectively fixedly connected to a stop block 9 and a stop block 11. The action of the stop blocks 9 and 11 can prevent the movable plate 4 from falling off the outer periphery of the lead screw 8 and slide rod 10.

[0037] Reference Figures 3-5The clamping block 5 is fitted with an anti-slip pad 15 on its outer periphery. A round rod 21 is fixedly connected to the middle of the clamping block 5. A locking rod 26 is slidably connected to the middle of the clamping block 5. The other end of the locking rod 26 passes through the anti-slip pad 15 and is fixedly connected to a locking plate 14. A pull plate 13 is fixedly connected to the outside of the locking plate 14. An elastic component is installed between the round rod 21 and the pull plate 13. The elastic component includes a slider 24. The slider 24 is slidably connected to the outer periphery of the round rod 21. A compression spring 23 is fitted on the outer periphery of the round rod 21. A connecting rod 22 is rotatably connected to the middle of the slider 24. The other end of the connecting rod 22 is rotatably connected to the side of the pull plate 13 near the clamping block 5. A pull rod 20 is fixedly connected to the side of the pull plate 13 away from the clamping block 5. A locking hole 25 is opened in the middle of the clamping block 5. The locking rod 26 is slidably connected to the middle of the locking hole 25. The anti-slip pad 15 on the outer periphery of the clamping block 5 can prevent wear on the contact surface between the clamping block 5 and the round material 6 after prolonged use. After prolonged use, the pull rod 20 can be pulled to drive the pull plate 13, so that the pull plate 13 drives the clamping rod 26 through the clamping plate 14 to slide out from between the clamping block 5 and the anti-slip pad 15, thereby allowing the worn anti-slip pad 15 to be replaced. When the pull plate 13 is pulled, it will drive the connecting rod 22 to pull the slider 24 to slide around the outer periphery of the round rod 21 and compress the compression spring 23, so that the new anti-slip pad 15 can be placed on the outer periphery of the clamping block 5. After releasing the pull rod 20, the pull plate 13 is pushed by the compression spring 23 to reset, thereby driving the clamping rod 26 to pass through the anti-slip pad 15 and insert into the clamping hole 25 to fix the anti-slip pad 15 in place. This avoids wear on the contact surface of the clamping block 5 and requires overall replacement, saving replacement costs.

[0038] Working principle: First, the servo motor 7 is driven so that the movable plate 4 can move around the outer periphery of the lead screw 8, thereby driving one set of clamping blocks 5 to move closer to another set of clamping blocks 5. Then, the round material 6 is fixed at multiple points through the four inclined sides to improve the fixing stability. At the same time, the electric push rod 17 is driven to adjust the vertical distance of the clamping blocks 5 before fixing, so that the clamping blocks 5 can fix round materials 6 of different diameters with the cooperation of the electric push rod 17 and the servo motor 7.

[0039] The anti-slip pad 15 on the outer periphery of the clamping block 5 can prevent wear on the contact surface between the clamping block 5 and the round material 6 during long-term use. After the anti-slip pad 15 wears out after long-term use, the pull rod 20 is pulled to drive the clamping plate 14, so that the clamping plate 14 drives the clamping rod 26 to slide out from the middle of the clamping block 5 and the anti-slip pad 15, so as to facilitate the replacement of the anti-slip pad 15, ensure the friction between the anti-slip pad 15 and the round material 6, and reduce the replacement cost after the clamp wears out.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
