Description

Technical Field

[0001] The invention belongs to the technical field of metal fittings processing, and in particular relates to a machining center clamping device for metal fittings processing. Background Art

[0002] Metal parts processing refers to the process of processing metal materials into parts of the required shape and size through machining, casting, forging, welding and other processes. This process is widely used in various industries, such as automobiles, aerospace, electronics, machinery manufacturing, etc. The following are some common processes and steps for metal parts processing.

[0003] In the prior art, when processing and welding some automobile parts, such as a round exhaust pipe, the centers of two parts of different models need to be overlapped to ensure the quality of welding and the strength of the structure. However, the traditional center clamping structure has certain defects and produces pungent odor during the processing, which is easy to affect personnel. In view of this, we propose a machining center clamping device for metal parts processing. Summary of the invention

[0004] The object of the present invention is to provide a clamping device for a machining center used for machining metal parts to solve the problems raised in the above-mentioned background technology.

[0007] Two driving assemblies, the two driving assemblies are respectively located on two U-shaped frames and are used to drive the corresponding two central clamping plates to move closer to or away from each other;

[0008] A hydraulic cylinder, wherein the hydraulic cylinder is fixedly mounted on the top of the processing cabinet, and an output shaft of the hydraulic cylinder passes through the top of the processing cabinet, extends into the inner cavity thereof and is fixed to one of the U-shaped frames;

[0009] A Y-shaped tube 1, wherein the Y-shaped tube 1 is fixedly installed in the processing cabinet and is located at the bottom of the inner cavity thereof, a protective net is installed in the inner thread of the top of the Y-shaped tube 1, and sealing disks are installed in the inner thread of the other two ends of the Y-shaped tube 1;

[0010] Y-shaped tube 2, the Y-shaped tube 2 is fixedly installed in the processing cabinet, and two ends of the Y-shaped tube 2 are connected to the Y-shaped tube 1, the inner wall of the Y-shaped tube 2 is connected to a motor through a plurality of round rods, a fan blade is fixedly installed on the output shaft of the motor, and a filter screen is threadedly installed on the other end of the motor.

[0011] In the present technical scheme, by setting two U-shaped frames, four center clamping plates, two driving components, a hydraulic cylinder, a plurality of ball grooves and a plurality of steel balls, it is ensured that when two different types of tubular auto parts are placed between the four center clamping plates respectively, there is only a single type of tubular auto parts between the two center clamping plates. Subsequently, by the two driving components, the two center clamping plates corresponding to the front sides of the two U-shaped frames are brought close to each other, and under the squeezing of a plurality of steel balls, the centers of the two different types of tubular auto parts are made to be on the same vertical line in the vertical direction. Subsequently, one of the U-shaped frames is driven downward by the output shaft of the hydraulic cylinder, and when one of the U-shaped frames moves downward, it will drive the corresponding center clamping plate and the tubular auto parts clamped by the two center clamping plates to move downward until the two different types of tubular auto parts are in contact, so that it is convenient for subsequent personnel to weld with a welding gun. Since the steel ball can rotate in the ball groove, it is ensured that when personnel use a welding gun to weld the contact points of two different types of tubular auto parts, they can also rotate the two tubular auto parts, so that it is convenient for personnel to perform welding processing.

[0012] In the above technical solution, further, one of the U-shaped frames is located directly above the other U-shaped frame, and the other U-shaped frame is tightly welded to the inner wall of the processing cabinet through a connecting block, and the other U-shaped frame and the connecting block are an integrally formed structure.

[0019] In the present technical solution, the electric push rod is connected to the power supply and started, and the output shaft of the electric push rod extends or contracts, so that the electric push rod as a whole becomes longer or shorter. When the electric push rod as a whole becomes longer, it will push the two connecting rods away from each other, and the two connecting rods will drive the two half gears to rotate. At the same time, one end of the two connecting rods also drives the two movable columns away from each other, thereby moving the two center clamping plates away from each other, making it convenient for personnel to place tubular automotive accessories between the two center clamping plates; when the electric push rod as a whole is shortened, it will pull the two connecting rods closer to each other, and the two connecting rods will also drive the two half gears to rotate. At the same time, one end of the two connecting rods also drives the two movable columns closer to each other, thereby moving the two center clamping plates closer to each other, ensuring that the two center clamping plates can clamp the placed tubular automotive accessories.

[0020] In the above technical solution, further, the two half gears are meshed, and one end of the connecting rod is rotatably connected to the movable column.

[0021] In this technical solution, it is ensured that one of the half gears can drive the other half gear to rotate, and at the same time, one end of the connecting rod can rotate in the movable column and drive the movable column to move on the limiting plate.

[0022] In the above technical solution, further, the movable column is slidably connected to one end of the limiting plate, and the limiting plate is in an L-shaped structure.

[0023] In this technical solution, the movable column can move on the limiting plate to ensure the structural stability of the movable column.

[0024] In the above technical solution, further, the half gear and the connecting rod are an integrally formed structure, and the movable column and the central clamping plate are an integrally formed structure.

[0028] In the above technical solution, further, it also includes:

[0030] In this technical solution, it is convenient for personnel to observe and the size of the outlet of the inner cavity of the processing cabinet is reduced.

[0031] In the above technical solution, further, the bottom of the inner cavity of the processing cabinet is communicated with the Y-shaped tube, and the bottom of the inner cavity of the processing cabinet is a funnel-shaped structure.

Subsequently, the two center clamping plates corresponding to the front sides of the two U-shaped frames are brought close to each other through the two driving components, and the centers of the two different types of tubular auto parts are vertically aligned under the pressure of the plurality of steel balls. The two U-shaped frames are on the same vertical line, and then, the output shaft of the hydraulic cylinder drives one of the U-shaped frames to move downward, and when one of the U-shaped frames moves downward, it drives the corresponding center clamping plate and the tubular auto parts clamped by the two center clamping plates to move downward, until two tubular auto parts of different models are in contact, which is convenient for subsequent personnel to weld with a welding gun. Since the steel ball can rotate in the ball groove, it is ensured that when personnel use a welding gun to weld the contact points of two tubular auto parts of different models, the two tubular auto parts can also be rotated, which is convenient for personnel to perform welding processing.

[0037] 2. The clamping device of the machining center for metal accessories processing, the personnel connect the motor to the power supply and start it, so that the output shaft of the motor drives the fan blades to rotate, and the fan blades suck the air in the processing cabinet into the Y-shaped tube 1.

The filter net can keep the debris in the Y-shaped tube 1. When the processing is completed, the sealing disk can be driven to rotate by holding the handle on the sealing disk. Under the action of the thread, the sealing disk is taken out of the Y-shaped tube 1, and the debris in the Y-shaped tube 1 will fall, which is convenient for the personnel to handle in a centralized manner.
