Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and more specifically to a multi-steel pipe machining fixture. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to position an object for processing or inspection. In the processing of steel pipes, clamping fixtures are typically used for clamping and positioning. Furthermore, to improve processing efficiency, multiple clamping openings are usually designed on a single fixture to hold multiple steel pipes for processing at the same time.

[0003] For example, the prior art disclosure number CN221539484U describes a multi-steel pipe processing fixture for steel pipe production. This utility model allows the hollow column to be disassembled by rotating a screw and then rotating the rotating plate and the hollow column. The hollow column is no longer locked in the slot, and the entire fixture can then be disassembled. This solves the problem of the steel pipe fixture being inconvenient to replace with other specifications of fixtures and improves the convenience of disassembling the fixture.

[0004] However, the existing technology has the following problems in use: when workers place long steel pipes for processing, the part of the steel pipe away from the clamp will fall due to gravity, causing the steel pipe to tilt and shift. Workers need to hold the steel pipe down by hand, which affects the processing efficiency. Since multiple steel pipes need to be placed at one time, multiple workers are required to cooperate in the installation, increasing the workload. Moreover, the existing clamps are large in size and inconvenient to carry and use. Based on this, the present invention provides a multi-steel pipe processing clamp. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a multi-steel pipe processing fixture. Through the cooperation of a base, two clamping plates, and a cover plate, multiple steel pipes can be fixed for processing at one time, improving the processing efficiency of steel pipes. Furthermore, the support plate supports multiple steel pipes at the bottom away from the base, preventing the steel pipes from tilting when workers place several steel pipes one by one. It is very time-saving and labor-saving to use. In addition, the close proximity of the support plate and base reduces the volume occupied and makes it easy to carry, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-steel pipe processing fixture, including a base, the top of which has a plurality of mounting holes arranged in a linear array, and two clamping plates are provided above each mounting hole. The two clamping plates are installed in the mounting holes by an adjustment component. An upper pressing component is provided above the base, and a support plate is provided at the rear end of the base. The support plate is connected to the base by a scissor-type connector. The scissor-type connector includes two connecting rods, and sliders are fixed at both ends of the two connecting rods. The front end of the support plate and the rear end of the base are provided with the same number of sliding grooves as the sliders, and the sliders are disposed in the sliding grooves.

[0007] In a preferred embodiment, the pressing assembly includes a cover plate, the bottom of which is fixed to the base by two electric push rods. The base has mounting slots on both sides of its top, and the two electric push rods are fixed in the two mounting slots respectively. The mounting slots limit the movement of the electric push rods, thereby improving their stability during use.

[0008] In a preferred embodiment, a movable handle is fixedly provided at the rear end of the support plate. The movable handle is located at the center of the rear end of the support plate, which facilitates the worker to pull the support plate to move and quickly adjust the position of the support plate.

[0009] In a preferred embodiment, a rectangular groove is provided at the rear end of the base, and the rectangular groove is connected to two sliding grooves at the rear end of the base for storing the connecting rod.

[0010] In a preferred embodiment, the adjusting assembly includes a slide rail, which is detachably installed in a mounting hole. A lead screw is rotatably provided inside the slide rail, and two symmetrically distributed nut blocks are threadedly connected to the lead screw. The threads of the two nut blocks and the lead screw have opposite directions, so that the two nut blocks move in opposite directions. The two nut blocks are detachably connected to the bottom of two clamping plates, which facilitates the subsequent disassembly and replacement of the clamping plates.

[0011] In a preferred embodiment, a motor is fixedly embedded on one side of the outer wall of each slide rail. One end of the motor output shaft passes through the slide rail and is fixed to one end of the lead screw. The motor drives the lead screw to rotate, thereby improving the fixing efficiency of the steel pipe.

[0012] In a preferred embodiment, both the top of the base and the top of the support plate are machined with a plurality of fixing holes arranged in a linear array. The provision of multiple fixing holes facilitates the use of bolts for fixing by the workers, thereby improving the stability of the base and the support plate.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a base, two clamping plates and a cover plate to fix multiple steel pipes for processing at one time, thereby improving the processing efficiency of steel pipes. The support plate supports multiple steel pipes at the bottom away from the base, preventing the steel pipes from tilting when workers place several steel pipes one by one. It is very time-saving and labor-saving to use. In addition, the support plate can be moved back to the base to reduce the overall volume of the fixture and make it easy to carry.

[0015] 2. The motor drives the lead screw to rotate, and the two nut blocks on the lead screw drive the two clamping plates to move synchronously. This can automatically and firmly clamp the steel pipe, preventing the steel pipe from swaying from side to side and affecting the processing. It can also adjust the distance between the two clamping plates, so as to be suitable for steel pipes of different diameters and improve the practicality of this fixture. Attached Figure Description

[0026] 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.

[0027] Refer to the instruction manual appendix Figures 1-6 This utility model provides a multi-steel pipe processing fixture, including a base 1. The top of the base 1 has a plurality of mounting holes 2 arranged in a linear array. Each mounting hole 2 has two clamping plates 3 above it. The two clamping plates 3 are installed in the mounting holes 2 through an adjusting component 4. The base 1 has an upper pressing component 5 above it. Specifically, the upper pressing component 5 includes a cover plate 51. The bottom of the cover plate 51 is fixed to the base 1 through two electric push rods 52. The top two sides of the base 1 have mounting grooves 53, and the two electric push rods 52 are respectively fixed in the two mounting grooves 53.

[0028] The base 1 has a support plate 6 at its rear end, and a movable handle 8 is fixedly provided at the rear end of the support plate 6. The movable handle 8 is located at the center of the rear end of the support plate 6, which facilitates the operation of the support plate 6 by the operator. The support plate 6 and the base 1 are connected by a scissor-type connector 7. The scissor-type connector 7 includes two connecting rods 71, and sliders 72 are fixedly provided at both ends of the two connecting rods 71. The front end of the support plate 6 and the rear end of the base 1 are provided with the same number of sliding grooves 73 as the sliders 72. The sliders 72 are located in the sliding grooves 73. Furthermore, a rectangular groove 9 is provided at the rear end of the base 1. The rectangular groove 9 is connected to the two sliding grooves 73 at the rear end of the base 1 and is used to accommodate the connecting rods 71.

[0029] Both the top of the base 1 and the top of the support plate 6 are machined with multiple fixing holes 10 arranged in a linear array. The multiple fixing holes 10 facilitate the use of bolts by the staff to fix them, thereby improving the stability of the base 1 and the support plate 6.

[0030] In actual use, the worker first grasps the movable handle 8 and pulls the support plate 6 to move it behind the base 1. The support plate 6 is connected to the base 1 via two connecting rods 71. Then, bolts are passed through the fixing holes 10 on the support plate 6 to fix the support plate 6 to the plane. A steel pipe can then be placed between the two clamping plates 3, and the adjusting component 4 is used to drive the two clamping plates 3 to clamp the steel pipe. Multiple mounting holes 2 on the base 1 are each equipped with two clamping plates 3 at their tops. Therefore, multiple steel pipes can be placed for processing at once, thereby improving processing efficiency. The support plate 6 provides support at the bottom of multiple steel pipes, preventing the work from being interrupted. When workers place several steel pipes in sequence, the pipes tilt upwards, eliminating the need for workers to constantly hold them in place by hand. This method is very time-saving and labor-saving. After all the steel pipes have been placed, two electric push rods 52 are simultaneously shortened, which causes the cover plate 51 to press down on the top of the steel pipes for fixation. Finally, the cover plate 51, base 1, and clamping plate 3 are used to firmly fix the steel pipes for processing, preventing them from shaking during processing. When finished, workers push the support plate 6 closer to the base 1 to reduce the overall size of the fixture, making it very convenient to carry.

[0031] Refer to the instruction manual appendix Figure 2 , Figure 4 and Figure 6 The adjusting component 4 includes a slide rail 41, which is detachably installed in the mounting hole 2. A lead screw 42 is rotatably provided inside the slide rail 41. Two symmetrically distributed nut blocks 43 are threadedly connected to the lead screw 42. The threads of the two nut blocks 43 and the lead screw 42 are opposite, so that the two nut blocks 43 move in opposite directions. The two nut blocks 43 are detachably connected to the bottom of the two clamping plates 3 respectively. A motor 44 is fixedly embedded on one side of the outer wall of each slide rail 41. One end of the output shaft of the motor 44 passes through the slide rail 41 and is fixed to one end of the lead screw 42.

[0032] The motor 44 drives the lead screw 42 to rotate, and the two nut blocks 43 on the lead screw 42 move relative to each other, so as to automatically clamp the steel pipe firmly and prevent the steel pipe from swaying left and right and affecting the processing. Furthermore, the distance between the two clamping plates 3 is adjustable under the action of the nut blocks 43, so as to be suitable for steel pipes of different diameters. It is worth noting that the maximum applicable steel pipe diameter does not exceed the maximum distance between the two clamping plates 3.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
