Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a double-station synchronous feeding mechanism for machining stainless steel pipes. Background Art

[0002] The steel industry is one of the important pillar industries of the national economy. It is of great significance to promote economic development, promote industrial upgrading and enhance international competitiveness. Among them, products produced by stainless steel are widely used in people's livelihood and science and technology fields.

[0003] In the processing of stainless steel pipes, a feeding mechanism is needed to speed up the efficiency of production and processing. The existing stainless steel pipe feeding mechanism controls the grippers to clamp the steel pipes through a control device to achieve the purpose of feeding. However, the specifications of stainless steel pipes are different. Some steel pipes can be clamped and fed by changing the distance between the grippers, but some steel pipes need to be clamped by other types of grippers. After being used for too long, the surface of the grippers will be damaged due to oxidation. If the grippers are not replaced in time, the grippers will cause friction on the surface of the stainless steel pipe, thereby affecting the appearance and quality of the stainless steel pipe.

[0004] In order to solve the above problems, the present application proposes a double-station synchronous feeding mechanism for stainless steel pipe machining. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a double-station synchronous feeding mechanism for stainless steel pipe machining, including a mechanical arm, a connecting plate is rotatably provided on the mechanical arm, a control device is fixedly provided at the bottom of the connecting plate, a mounting frame is fixedly provided at the bottom of the control device, a clamp is slidably provided on the mounting frame, the control device includes a first slide groove, a slide rod and a slide block, the mounting frame includes a second slide groove and a third slide groove, and the clamp includes a protrusion, a bolt and a protective cover.

[0006] Preferably, the slide bar is slidably connected in the first slide groove and the second slide groove, the slider is slidably connected in the third slide groove, and the slider is fixedly connected to the slider.

[0007] Preferably, the shapes of the upper portion and the middle portion of the slide bar match the shape of the first slide groove, and the shape of the lower portion of the slide bar matches the shape of the bottom of the mounting bracket.

[0008] Preferably, the width of the middle portion of the slide rod is equal to the width of the second slide groove, and the height of the slide block is equal to the height of the third slide groove.

[0009] Preferably, the length of the second chute is equal to the length of the third chute.

[0010] Preferably, the clamp is slidably connected to the bottom of the mounting frame, the protrusion is fixedly connected to the clamp, the protrusion is slidably connected to the outside of the third slide groove, and the protective cover is fixedly connected to the outer surface of the clamp.

[0011] Preferably, threaded holes are provided on the slider and the protrusion, and the bolts are screwed in the threaded holes.

[0012] Preferably, the protective cover is made of ceramic fiber.

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] The utility model arranges a mounting frame between the control system and the gripper, and uses the control system to control the slide bar to slide in the first slide groove, thereby driving the slider to slide in the third slide groove. Since the slider is fixed together by bolts and protrusions, the gripper and the protrusion will move together with the slider, and two groups of grippers are used to realize double-station synchronous clamping and feeding of stainless steel pipes. The original control system directly controls the gripper in a way that it is changed to indirectly control the gripper through the slide bar and the mounting frame, so that the gripper can be disassembled and replaced more quickly, which meets the use of more grippers, improves the application range of steel pipes, and is convenient for staff to replace damaged grippers. At the same time, a protective cover made of ceramic fiber is put on the surface of the gripper, so that the surface of the gripper cannot directly contact the steel pipe, thereby avoiding damage to the surface of the steel pipe due to excessive clamping force or damage and oxidation of the gripper surface, thereby improving the quality and appearance of the product.
