Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe clamping machines, and particularly relates to a clamping machine for stainless steel pipes. Background Technique

[0002] A steel pipe clamping machine is a mechanical device specifically used for processing steel pipes, and it can perform various processing operations such as clamping, bending, and cutting on steel pipes. This kind of machine is usually applied in the metal processing industry, especially in fields such as construction, automotive, and furniture manufacturing, for making various steel pipe products.

[0003] The utility model patent application document with the publication number of "CN219901087U" discloses a clamping machine for stainless steel pipes, belonging to the technical field of clamping machines, including a cuboid-shaped base. On the top surface of the base, a support table is provided on one wide side. On the top surface of the support table, a bearing table is provided. Above the bearing table, a top seat is provided. On both sides of the support table on the top surface of the base, a hydraulic cylinder is provided. The hydraulic cylinder drives a hydraulic shaft with the top end fixedly connected to the top seat. On the top seat, a pressing table is provided. The bottom surface of the pressing table and the top surface of the bearing table are both concave to form an arc-shaped receiving surface. In the middle of the top surface of the base on the other wide side, a bearing groove parallel to the length direction of the base is opened. A bearing block is slidably connected in the bearing groove. On the top surface of the bearing block, a telescopic cylinder for driving a vertical telescopic shaft is provided. The top end of the telescopic shaft is provided with a support block, and the top surface of the support block is concave in an arc shape. Through the upper and lower two receiving surfaces in the shape of an arc, it can match the cylindrical shape of the stainless steel pipe, making the clamping more tight and stable, and avoiding the situations of slipping under pressure and local depression and deformation under concentrated stress during the clamping process.

[0004] The clamping machine for stainless steel pipes disclosed in the above document has the following defects: This technical solution cannot conveniently clamp steel pipes of different sizes during use, and the practicability is relatively low.

[0005] It can be seen from this that the existing clamping machines for stainless steel pipes do not have a clamping structure that can conveniently clamp steel pipes of different sizes, and it is necessary to improve the existing deficiencies to provide a clamping machine for stainless steel pipes. Summary of the Invention

[0006] The purpose of the utility model is to provide a clamping machine for stainless steel pipes to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model is a clamping machine for stainless steel pipes, including a mounting base. On the upper surface of the mounting base, two groups of hydraulic cylinders are fixedly installed. The output ends of the two groups of hydraulic cylinders are both installed with hydraulic shafts. One end of the hydraulic shaft is fixedly installed with a top plate. Clamping components are provided on the outer surfaces of the mounting base and the top plate.

[0009] Furthermore, the clamping assembly includes a fixed seat, a sliding groove, a driving motor, a bidirectional lead screw, a movable block, a sliding block, a fixed rod, a clamping block and an anti-slip pad. One group of the fixed seats is fixedly installed on the upper surface of the mounting base, and the other group of the fixed seats is installed on the lower surface of the top plate. A sliding groove is formed in the inner wall of the fixed seat. The number of the sliding grooves is fixed at two. A driving motor is fixedly installed on one side of the fixed seat. A bidirectional lead screw is rotatably connected to the inner wall of the fixed seat. The bidirectional lead screw is connected to the output end of the driving motor. The outer surface of the bidirectional lead screw is slidably connected with a movable block. The number of the movable blocks is fixed at two. Sliding blocks are fixedly installed on both sides of the movable block. The sliding blocks are slidably connected with the sliding grooves. Fixed rods are fixedly installed on the upper surfaces of the movable blocks. A clamping block is fixedly installed at one end of the fixed rod. An anti-slip pad is fixedly installed on the outer surface of the clamping block.

[0010] Furthermore, guide rails are fixedly installed on both sides of the mounting base, and limiting blocks are slidably connected to the outer surfaces of the guide rails.

[0011] Furthermore, connecting plates are fixedly installed on the upper surfaces of the two groups of limiting blocks, and a fixing plate is fixedly installed between the two groups of connecting plates.

[0012] Furthermore, a push rod machine is fixedly installed on the upper surface of the fixing plate, and a support plate is installed at the output end of the push rod machine.

[0013] Furthermore, a handle is fixedly installed on the front side of the fixing plate, and a cleaning brush is arranged on the lower surface of the fixing plate. The cleaning brush is in contact with the mounting base.

[0014] The utility model has the following beneficial effects:

[0015] (1) In the utility model, the steel pipe is placed in the clamping assembly arranged on the mounting base, and then the driving motor on one side of the fixed seat is started. The output end of the driving motor is connected with the bidirectional lead screw. The bidirectional lead screw starts to rotate by the power of the motor. Since the two movable blocks on the bidirectional lead screw are threadedly connected with the lead screw, when the lead screw rotates, the movable blocks will move relatively on the lead screw, that is, one moves inward and the other moves outward. The sliding blocks on both sides of the movable block slide in the sliding grooves formed in the inner wall of the fixed seat, ensuring the smooth linear movement of the movable block. With the movement of the movable block, the fixed rod fixed on its upper surface drives the clamping block to move, realizing the clamping or loosening of the stainless steel pipe. The anti-slip pad on the outer surface of the clamping block increases the friction force between the clamping block and the stainless steel pipe. Then the hydraulic cylinder is started to drive the top plate to move downward by the hydraulic shaft, and the above operation is repeated for the clamping assembly arranged on the lower surface of the top plate, and the clamping and fixing of the steel pipe can be completed. The setting of multiple groups of clamping blocks can deal with steel pipes with different diameters, which is convenient to use and increases the practicability.

[0016] (2) In the present utility model, by pulling the handle provided on the fixed plate, the connecting plate drives the two limiting blocks to slide on the surface of the guide rails provided on both sides of the mounting base, so as to adjust the positions of the push rod machine and the supporting plate, avoiding the situation that the guiding grooves are opened on the upper surface of the mounting base, resulting in inconvenient cleaning due to dust accumulation. Through the arrangement of the cleaning brush, the surface of the mounting base can be assisted in cleaning when the fixed plate moves, increasing the practicability.

[0017] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0026] Please refer to Figure 1 - Figure 4 As shown in the figure, the utility model relates to a chucking machine for stainless steel pipes, which comprises an installation base 1. Two groups of hydraulic cylinders 2 are fixedly installed on the upper surface of the installation base 1. The output ends of the two groups of hydraulic cylinders 2 are both installed with hydraulic shafts 201. One end of the hydraulic shaft 201 is fixedly installed with a top plate 3. Clamping assemblies 4 are arranged on the outer surfaces of the installation base 1 and the top plate 3;

[0027] The clamping assembly 4 comprises a fixed seat 401, a sliding groove 402, a driving motor 403, a bidirectional lead screw 404, a movable block 405, a sliding block 406, a fixed rod 407, a clamping block 408 and an anti-slip pad 409. One group of fixed seats 401 is fixedly installed on the upper surface of the installation base 1, and the other group of fixed seats 401 is installed on the lower surface of the top plate 3. A sliding groove 402 is formed in the inner wall of the fixed seat 401. The number of the sliding grooves 402 is fixed to two. A driving motor 403 is fixedly installed on one side of the fixed seat 401. A bidirectional lead screw 404 is rotatably connected in the inner wall of the fixed seat 401. The bidirectional lead screw 404 is connected with the output end of the driving motor 403. The outer surface of the bidirectional lead screw 404 is slidably connected with a movable block 405. The number of the movable blocks 405 is fixed to two. Sliding blocks 406 are fixedly installed on both sides of the movable block 405. The sliding blocks 406 are slidably connected with the sliding grooves 402 formed in the inner wall of the fixed seat 401. Fixed rods 407 are fixedly installed on the upper surfaces of the movable blocks 405. One end of the fixed rod 407 is fixedly installed with a clamping block 408. An anti-slip pad 409 is fixedly installed on the outer surface of the clamping block 408;

[0028] By placing the steel pipe in the clamping assembly 4 arranged on the installation base 1, then starting the driving motor 403 on one side of the fixed seat 401, the output end of the driving motor 403 is connected with the bidirectional lead screw 404. The bidirectional lead screw 404 starts to rotate by the power of the motor. Since the two movable blocks 405 on the bidirectional lead screw 404 are threadedly connected with the lead screw, when the lead screw rotates, the movable blocks 405 will move relatively on the lead screw, that is, one moves inwards and the other moves outwards. The sliding blocks 406 on both sides of the movable block 405 slide in the sliding grooves 402 formed in the inner wall of the fixed seat 401, ensuring the smooth linear movement of the movable block 405. As the movable block 405 moves, the fixed rod 407 fixed on its upper surface drives the clamping block 408 to move, realizing the clamping or loosening of the stainless steel pipe. The anti-slip pad 409 on the outer surface of the clamping block 408 increases the friction force between the stainless steel pipe. Then start the hydraulic cylinder 2 to make the hydraulic shaft 201 drive the top plate 3 to move downwards, and then repeat the above operation on the clamping assembly 4 arranged on the lower surface of the top plate 3, and the clamping and fixing of the steel pipe can be completed. The setting of multiple groups of clamping blocks 408 can cope with steel pipes of different diameters, which is convenient to use and increases the practicability;

[0029] On both sides of the mounting base 1, guide rails 5 are fixedly installed, and limiting blocks 6 are slidably connected to the outer surfaces of the guide rails 5;

[0030] On the upper surfaces of the two groups of limiting blocks 6, connecting plates 7 are fixedly installed, and a fixing plate 8 is fixedly installed between the two groups of connecting plates 7;

[0031] On the upper surface of the fixing plate 8, a push rod machine 9 is fixedly installed, and a supporting plate 10 is installed at the output end of the push rod machine 9;

[0032] On the front side of the fixing plate 8, a handle 11 is fixedly installed, and a cleaning brush 12 is arranged on the lower surface of the fixing plate 8, and the cleaning brush 12 abuts against the mounting base 1.

[0033] During use, first place the steel pipe in the clamping assembly 4 arranged on the mounting base 1, and then start the drive motor 403 on one side of the fixed seat 401. The output end of the drive motor 403 is connected to the bidirectional lead screw 404. Through the power of the motor, the bidirectional lead screw 404 starts to rotate. The two movable blocks 405 on the bidirectional lead screw 404 are threadedly connected to the lead screw. Therefore, when the lead screw rotates, the movable blocks 405 will move relative to each other on the lead screw, that is, one moves inward and the other moves outward. The sliders 406 on both sides of the movable block 405 slide in the sliding grooves 402 opened on the inner wall of the fixed seat 401, ensuring that the movable block 405 moves smoothly along a straight line. As the movable block 405 moves, the fixed rod 407 fixed on its upper surface drives the clamping block 408 to move, realizing the clamping or loosening of the stainless steel pipe. The anti-slip pad 409 on the outer surface of the clamping block 408 increases the friction force with the stainless steel pipe. Then start the hydraulic cylinder 2 to make the hydraulic shaft 201 drive the top plate 3 to move downward, and then repeat the above operation for the clamping assembly 4 arranged on the lower surface of the top plate 3, and the clamping and fixing of the steel pipe can be completed. The setting of multiple groups of clamping blocks 408 can cope with steel pipes of different diameters, which is convenient to use and increases the practicability. By pulling the handle 11 arranged on the fixing plate 8, the connecting plate 7 drives the two groups of limiting blocks 6 to slide on the surfaces of the guide rails 5 arranged on both sides of the mounting base 1, so as to adjust the positions of the push rod machine 9 and the supporting plate 10, avoiding the situation that the guiding grooves are opened on the upper surface of the mounting base 1, resulting in inconvenient cleaning due to dust accumulation. Start the push rod machine 9 to drive the supporting plate 10 to assist in supporting the steel pipe. Through the setting of the cleaning brush 12, the surface of the mounting base 1 can be assisted in cleaning when the fixing plate 8 moves, increasing the practicability.
