Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a precision processing device for metal parts. Background Art

[0002] Metal parts are widely used in various mechanical equipment. The production of metal parts includes processes such as cutting, grinding, and drilling. The drilling operation during the processing of metal parts is carried out on a drilling machine. A drilling machine refers to a general term for machinery and equipment that uses a tool harder and sharper than the target object to leave a cylindrical hole or cavity on the target object through rotary cutting or rotary extrusion.

[0003] When performing a drilling operation on a metal part, it is necessary to clamp and fix the metal part. However, the current equipment cannot be adjusted according to the shape and specifications of the workpiece during fixation, resulting in a poor fixation effect for some workpieces after fixation, and the single perforation method affects the subsequent overall processing process. Summary of the Utility Model

[0004] The utility model discloses a precision processing device for metal parts, aiming to solve the technical problems that the existing equipment cannot be adjusted according to the shape and specifications of the workpiece, resulting in a poor fixation effect and changing the perforation method.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A precision processing device for metal parts includes an arc-shaped frame. Two symmetrical support frames are fixedly connected to both sides of the arc-shaped frame. Sliding grooves are provided on the support frames. T-shaped plates are movably connected inside the sliding grooves. And telescopic hydraulic rods are fixedly connected to the support frames. The telescopic ends of the telescopic hydraulic rods are fixedly connected to the T-shaped plates. Rotating motors are fixedly connected to the upper sides of the two T-shaped plates. The output ends of the rotating motors are connected to a rotating shaft through couplings. And a perforation is provided on the T-shaped plate. The other end of the rotating shaft passes through the perforation of the T-shaped plate and is fixedly connected to a hand claw. The hand claw includes two fixed frames rotatably connected through bearings. The two fixed frames are symmetrically distributed. The front ends of the two fixed frames are rotatably connected to roller cylinders through bearings. And convex platforms are provided on the opposite sides of the two fixed frames. A tension spring is fixedly connected between the two convex platforms. A metal material part is arranged between the two hand claws.

[0007] By providing an arc-shaped frame, a support frame, telescopic hydraulic rods, T-shaped plates, rotary motors, rotary shafts, grippers, roller cylinders, tension springs and metal material parts, when processing metal materials, the positions of the support frames are fixed at both ends of the U-shaped frame, the grippers and roller cylinders at both ends fix the positions of the metal material parts, and two opposite telescopic hydraulic rods are used to synchronously extend and push the two T-shaped plates towards each other. During this process, the grippers and roller cylinders press and clamp the metal material parts synchronously from both sides, so that the metal material is pressed and fixed. The method of pressing and fixing in opposite directions ensures the fixing effect of the metal material. At the same time, the movable grippers can be adaptively adjusted according to the shape and specifications of the metal material (the grippers are limited and connected by tension springs, and the elastic properties of the springs are used to achieve the limiting effect), improving the application range of the device.

[0008] In a preferred solution, a side plate is provided below the arc-shaped frame. A U-shaped scale is fixedly connected to the front side of the side plate. A semi-circular groove is formed in the side plate, and the lower end of the arc-shaped frame is semi-circular. The arc-shaped frame is rotatably connected in the semi-circular groove of the side plate. A pointer is fixedly connected to the outside of the arc-shaped frame. The pointer and the U-shaped scale are on the same side. A base is fixedly connected to the side of the side plate away from the U-shaped scale. A drive motor is fixedly connected to the base. The output end of the drive motor is connected to a short shaft through a coupling. The other end of the short shaft is fixedly connected to a driving gear. A gear shaft is fixedly connected to the side of the arc-shaped frame away from the pointer. The gear shaft and the driving gear are meshed through a tooth groove. A gantry is fixedly connected to the upper side of the base. A lifting motor is fixedly connected to the upper side of the gantry. The output end of the lifting motor is connected to a lead screw through a coupling. The other end of the lead screw passes through the gantry and is rotatably connected to the base through a bearing.

[0009] By providing a side plate, a U-shaped scale, a pointer, a gear shaft, a drive motor, a base, a gantry, a lead screw and a lifting motor, before processing metal materials, first determine the drilling method. If the inclined cutting drilling method is adopted, the drive motor must be started to drive the gear shaft to rotate and adjust the angle. When facing metal material parts of different heights, the lifting motor drives the lead screw to rotate for linear lifting motion. During this process, the drilling angle is adjusted and determined through the pointer, better realizing the change of the drilling method. The lead screw converts the rotary motion into a linear motion to effectively adjust the height and depth of the drilling.

[0010] In a preferred embodiment, a connecting shaft is provided above the base. The connecting shaft is movably connected to the outside of the gantry. A through threaded hole is formed in the connecting shaft. The lead screw is rotatably connected to the inside of the threaded hole through the inner wall thread. And a U-shaped seat is fixedly connected to the connecting shaft. A motor box is fixedly connected to the U-shaped seat. And a variable-speed motor is fixedly connected to the inside of the motor box. A through hole is formed in the motor box. The output end of the variable-speed motor is connected to a rotating shaft through a coupling. And the other end of the rotating shaft passes through the through hole of the motor box and is fixedly connected to a drill chuck. A drill is fixedly connected to the drill chuck.

[0011] By providing a connecting shaft, a U-shaped seat, a motor box, a variable-speed motor, a drill chuck and a drill, when performing drilling operations, the drill is installed in the drill chuck. The variable-speed motor is started to control the speed of the drill rotation. During the process, the connecting shaft adjusts the height of the motor box through the feeding movement of the lead screw, so as to effectively adjust the drilling depth to meet the requirements of precision machining of metal parts.

[0012] As can be seen from the above, a metal part precision machining device provided by the present invention adopts an opposite pressing and fixing method, which ensures the fixing effect of the metal material. At the same time, the movable claws can be adaptively adjusted according to the shape and specifications of the metal material (the claws are limitedly connected by a tension spring, and the elastic property of the spring is used to achieve the limiting effect), improving the technical effect of the applicable range of the device, improving the singleness of metal part machining, and different machining methods can be used according to the clamping or pressing effect when facing different metal material specifications. Realize the technical effect of stable precision machining of various metal parts. When machining metal part materials with different angle cutting methods, the angle can be adjusted according to requirements, and the operation is fast and convenient.

A tension spring 15 is connected between the two convex platforms by bolts. A metal material part 7 is provided between the two claws 14.

[0022] Refer to Figure 1 , Figure 2 and Figure 3, in a preferred embodiment, a side plate 2 is provided below the arc-shaped frame 5. The front side of the side plate 2 is bolted with a U-shaped scale disk 3. A semi-circular groove is formed on the side plate 2, and the lower end of the arc-shaped frame 5 is semi-circular. The arc-shaped frame 5 is rotatably connected in the semi-circular groove of the side plate 2. A pointer 4 is bolted to the outside of the arc-shaped frame 5. The pointer 4 and the U-shaped scale disk 3 are on the same side. A base 1 is bolted to the side of the side plate 2 away from the U-shaped scale disk 3. A driving motor 9 is bolted to the base 1. The output end of the driving motor 9 is connected with a short shaft through a coupling. The other end of the short shaft is bolted with a driving gear. And a gear shaft 8 is bolted to the side of the arc-shaped frame 5 away from the pointer 4. The gear shaft 8 and the driving gear are engaged through a tooth groove. A gantry 17 is bolted to the upper side of the base 1. A lifting motor 20 is bolted to the upper side of the gantry 17. The output end of the lifting motor 20 is connected with a lead screw 19 through a coupling. And the other end of the lead screw 19 passes through the gantry 17 and is rotatably connected with the base 1 through a bearing.

[0023] Referring to Figure 1 and Figure 5 , in a preferred embodiment, a connecting shaft 18 is provided above the base 1. The connecting shaft 18 is slidably connected outside the gantry 17. A through threaded hole is formed in the connecting shaft 18. The lead screw 19 is rotatably connected through the inner wall thread inside the threaded hole.

[0024] Working principle: Before placing the processing material, the position needs to be adjusted through the T-shaped plate 11, that is, the rotating motors 12 on the two opposing T-shaped plates 11 are started to drive the rotating shafts 13 to rotate the grippers 14 at different angles to meet the pressing or clamping effects of metal material parts 7 with different shapes and specifications. When facing metal material parts 7 with different drilling angles, the driving motor 9 is used to drive the gear shaft 8 connected to the arc-shaped frame 5 to rotate the angle to meet the processing requirements. When facing metal material parts 7 with different heights, the lifting function of the lifting motor 20 is used to drive the lead screw 19 to convert the rotational motion into a linear motion to meet the processing requirements;

[0025] Before processing the metal material part 7, the positions of the support frames 6 at both ends of the U-shaped seat 21 are fixed, and the positions of the metal material part 7 are fixed by the grippers 14 and the roller cylinders 16 at both ends. Two opposite telescopic hydraulic rods 10 are used to extend synchronously to push the two T-shaped plates 11 closer to each other. During the process, the grippers 14 and the roller cylinders 16 press and clamp the metal material part 7 synchronously from both sides, so that the metal material part 7 is pressed and fixed.

[0026] First, determine the drilling method. If the inclined cutting drilling method is adopted, the drive motor 9 must be started to drive the gear shaft 8 to rotate and adjust the angle. When facing metal material parts 7 of different heights, the lifting motor 20 drives the lead screw 19 to rotate for linear lifting movement, and the drilling angle is adjusted and determined through the pointer 4 during the process.

During the process, the connecting shaft 18 adjusts the height of the motor box 22 through the feeding movement of the lead screw 19, so as to realize the processing of metal parts with different depths or different height specifications.
