Description

Technical Field

[0001] This utility model relates to the field of square tube clamping technology, and in particular to a square tube clamping tool for chamfering square tubes. Background Technology

[0002] When chamfering square tubes, the tubes need to be fixed in place using a square tube clamp. The positioning elements on the clamp hold the tube in a specific position, ensuring that the tube's position remains consistent during each processing step. This improves the stability of the processing and guarantees that the chamfered edge is accurately positioned on the square tube, meeting design requirements and improving processing quality. Furthermore, it prevents safety accidents caused by the square tube loosening or popping out during processing, ensuring the safety of operators and the normal operation of the processing equipment.

[0003] For example, announcement number CN212020032U describes a square tube clamp for chamfering square tubes, comprising a fixed base and a clamping plate. Two symmetrically arranged support blocks are fixedly connected to the top of the fixed base. The clamping plate is rotatably connected to the two support blocks via a rotating rod. One end of the rotating rod passes through one of the support blocks and extends outwards. A knob is fixedly connected to the extended end of the rotating rod. A locking rod is slidably inserted into one end of the knob. Multiple locking slots corresponding to the locking rod are arranged around the support block. A retaining sleeve is fixedly connected to the end of the locking rod near the support block, and a pull rod is fixedly connected to the end of the locking rod away from the retaining sleeve. The bottom of one end of the clamping plate is connected to the top of the fixed base via a first spring. This utility model, through a simple fixing mechanism, enables the device to quickly fix pipe fittings, thereby improving the efficiency of clamp fixing and disassembly.

[0004] In the current square tube processing flow, clamping typically relies on manual placement of the square tube onto the processing table, followed by a servo cylinder driving the clamping plate to complete the fixing process. However, this process has significant drawbacks. Manual placement makes it difficult to ensure precise positioning of the square tube, often requiring operators to repeatedly adjust the positioning manually based on experience. This makes the clamping process time-consuming and labor-intensive, significantly slowing down the processing pace. Especially when dealing with batch processing of square tubes of different sizes, frequent manual positioning operations consume a large amount of time, drastically reducing overall production efficiency and significantly increasing production costs. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides a square tube clamp for chamfering square tubes, which can automatically position square tubes of different sizes.

[0006] The technical solution adopted by this utility model is as follows: It includes a base and symmetrically arranged servo cylinders. The servo cylinders are fixedly installed on both sides of the upper end of the base. A clamping plate for fixing a square tube is fixedly installed at the output end of the servo cylinder. Square slots are opened on both sides of the upper end of the base, and square blocks are inserted into the square slots. A sliding groove is opened at the upper end of the square block, and a movable T-shaped positioning plate is installed in the sliding groove through a drive assembly. A rectangularly distributed lifting groove is opened at the upper end of the base, and a trapezoidal block is inserted into the lifting groove. One end of the trapezoidal block is connected to the square plate... The square blocks are fixedly connected, and a first spring is fixedly installed at the bottom of the lifting groove. The other end of the first spring is fixedly connected to the trapezoidal block. In use, the first spring is used to move the trapezoidal block.

The drive assembly is used to move the T-shaped positioning plate. The servo cylinder is used to move the clamping plate. One end of the servo cylinder is provided with a controller for controlling the servo cylinder. The square block can move inside the square groove.

[0007] Preferably, in order to buffer the square tube, a buffer pad is fixedly installed at one end of the clamping plate. The buffer pad is made of rubber and is used to buffer the impact force of the clamping plate on the square tube.

[0008] Preferably, in order to enable the T-shaped positioning plate to move, the drive assembly includes a threaded rod and a guide rod. The threaded rod is rotatably mounted in the sliding groove via a plane bearing. The threaded rod is threadedly connected to one end of the T-shaped positioning plate, and the threaded rod is used to adjust the position of the T-shaped positioning plate.

[0009] Preferably, in order to facilitate the rotation of the threaded rod, a rotating plate is fixedly installed at one end of the threaded rod.

[0010] Preferably, in order to enable the T-shaped positioning plate to move smoothly, the guide rod is fixedly installed at both ends inside the sliding groove, the T-shaped positioning plate is sleeved on the outside of the guide rod, and the guide rod plays a guiding and limiting role.

[0011] Preferably, in order to make the trapezoidal block move smoothly, a damping telescopic rod is installed inside the first spring, one end of the damping telescopic rod is fixedly installed in the lifting groove, and the free end of the damping telescopic rod is fixedly connected to the trapezoidal block.

[0012] The beneficial effects of this utility model are: when in use, this utility model automatically positions the square tube by setting a T-shaped positioning plate, which prevents the difficulty in ensuring the accurate positioning of the square tube when it is placed manually and requires manual adjustment and positioning, saving time and effort. Moreover, when processing square tubes of different sizes in batches, there is no need to perform frequent manual positioning, thereby improving the overall production efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0020] like Figures 1-5As shown, this embodiment provides a square tube clamp for chamfering square tubes, including a base 1 and symmetrically arranged servo cylinders 2. The servo cylinders 2 are fixedly installed on both sides of the upper end of the base 1. A clamping plate 3 for fixing the square tube is fixedly installed at the output end of the servo cylinder 2. Square grooves 4 are opened on both sides of the upper end of the base 1. Square blocks 5 are inserted into the square grooves 4. A sliding groove 6 is opened on the upper end of the square blocks 5. A movable T-shaped positioning plate 8 is installed in the sliding groove 6 through a drive assembly 7. A rectangular lifting groove 9 is opened on the upper end of the base 1. A trapezoidal block 10 is inserted into the lifting groove 9. One end of the trapezoidal block 10 is connected to the square plate 3. 1. The square block 5 is fixedly connected to the servo cylinder 2. A first spring 12 is fixedly installed at the bottom of the lifting groove 9. The other end of the first spring 12 is fixedly connected to the trapezoidal block 10. A buffer pad 13 made of rubber is fixedly installed at one end of the clamping plate 3. A damping telescopic rod 14 is installed inside the first spring 12. One end of the damping telescopic rod 14 is fixedly installed in the lifting groove 9. The free end of the damping telescopic rod 14 is fixedly connected to the trapezoidal block 10. When using the servo cylinder 2, the existing structure can be used. First, manually place the square tube between the T-shaped positioning plates 8. The T-shaped positioning plates 8 automatically position the square tube. To ensure precise positioning of the square tube without manual adjustment, saving time and effort and reducing the need for frequent manual positioning, thus improving overall production efficiency, the servo cylinders 2 on both sides are manually activated. The servo cylinders 2 drive the clamping plates 3 to move towards each other. During this movement, the clamping plates 3 cause the trapezoidal block 10 to move downwards within the lifting groove 9. At this time, the damping telescopic rod 14 retracts, and the first spring 12 is compressed. Pressure plates are provided on both sides of one end of the clamping plate 3 to limit the position of the trapezoidal block 10, ensuring that it does not move upwards during the fixing of the square tube. Then, the trapezoidal block 10, through the square plate 11, drives the square tube... The square block 5 moves downward within the square groove 4, facilitating the clamping plate 3 to fix the square tube. Then, the square tube is chamfered using appropriate equipment. After processing, the clamping plate 3 is reset by the servo cylinder 2. Under the deformation force of the first spring 12, the T-shaped positioning plate 8 and the trapezoidal block 10 automatically reset. The friction generated inside the damping telescopic rod 14 can eliminate the elastic potential energy generated by the first spring 12, preventing the trapezoidal block 10 from moving repeatedly. When it is necessary to fix square tubes of different sizes, the position of the T-shaped positioning plate 8 is adjusted by the drive component 7, thereby positioning square tubes of different sizes. It is highly practical.

[0021] like Figure 3 and Figure 4As shown, the drive assembly 7 includes a threaded rod 701 and a guide rod 702. The threaded rod 701 is rotatably mounted in the sliding groove 6 via a plane bearing. The threaded rod 701 is threadedly connected to one end of the T-shaped positioning plate 8. A rotating plate 703 is fixedly mounted on one end of the threaded rod 701. The guide rod 702 is fixedly mounted at both ends inside the sliding groove 6. The T-shaped positioning plate 8 is sleeved on the outside of the guide rod 702. In use, when it is necessary to fix square tubes of different sizes, the rotating plate 703 is manually rotated first, and the threaded rod 701 rotates accordingly, causing one end of the T-shaped positioning plate 8 to move in the sliding groove 6, thereby adjusting the distance between the T-shaped positioning plates 8 and fixing square tubes of different sizes. At this time, the guide rod 702 plays a guiding and limiting role, allowing the T-shaped positioning plate 8 to move smoothly.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
