Description

Technical Field

[0001] The invention belongs to the technical field related to machine tool trusses, and specifically discloses a truss structure for a numerically controlled machine tool. Background Art

[0002] CNC machine tool loading and unloading manipulator is a rectangular coordinate robot manipulator used for automatic loading and unloading of CNC machine tools. It can realize automatic control, repeated programming, multi-function, multi-degree of freedom, and automatic equipment with the degrees of freedom of movement in a spatial right-angle relationship. The existing manipulators of this type are usually based on trusses and combined with CNC machine tools. They can realize automatic grasping, loading and unloading of workpieces in all process steps, which can greatly save labor costs; During the processing of a workpiece, different processing procedures need to be completed on different machine tools. Since machine tools can be divided into many types according to processing accuracy, processing methods, etc., and their uses are not exactly the same, different processes of the workpiece need to be completed on machine tools with different processing technologies. The existing technology uses a truss as a base to transfer workpieces between different machine tools over a large range.

[0003] However, after the workpiece is processed on the machine tool responsible for one of the working procedures, the existing conveying mechanism for loading the workpiece can only transfer the processed workpiece once. When faced with a large range of workpiece transfers, the machine tool responsible for workpiece processing needs to cooperate with the reciprocating conveying mechanism to process the workpieces transferred one by one, which will affect the processing efficiency of the workpiece. At the same time, burrs will usually remain on the inner corners of the workpiece during the processing, which will affect the accuracy of use during subsequent processing. For this reason, we need to make improvements. Summary of the invention

The nozzle 27 can not only blow away soot and chips, but also reduce the temperature of the cast workpiece 31.

[0024] The connecting rod 37 is internally rotatably interspersed with the mounting rod 34, and the outside of the mounting rod 34 and above the connecting rod 37 are both equipped with transmission wheels, and the outsides of the two sets of transmission wheels on the same side are commonly equipped with a synchronous belt 30, and a second motor 35 is fixedly installed on the upper end of one of the mounting rods 34 on the same side, and the outside of the second motor 35 is connected to the upper end surface of the connecting rod 37 at the corresponding position through an L-shaped rod, and a grinding rod 32 is fixedly installed on the lower part of the outside of the mounting rod 34; like Figure 5 and Figure 6 As shown, the second motor 35 drives the corresponding mounting rod 34 to rotate, and under the transmission connection of the transmission wheel and the synchronous belt 30, the mounting rod 34 on the other side also rotates, thereby, the mounting rod 34 and the grinding rod 32 can grind the inner corner of the workpiece 31; The use height of the grinding rod 32 can be raised and lowered by the first hydraulic cylinder 6 to penetrate into the workpiece 31. The grinding rod 32 is a grinding stick with a diamond brush. With the connection of the connecting rod 37 , the mounting rod 34 can be mounted outside the fixing ring 28 for use.

[0025] A U-shaped frame 11 is fixedly arranged outside the guide plate 15, a baffle 18 is slidably installed inside the U-shaped frame 11, a No. 1 screw 17 is rotatably installed inside the U-shaped frame 11, and the No. 1 screw 17 threadedly penetrates the inside of the baffle 18, a No. 1 motor 16 is fixedly installed at one end of the No. 1 screw 17, and the No. 1 motor 16 is fixedly connected to the U-shaped frame 11; like Figure 3 and Figure 4 As shown, the baffle 18 is driven by the No. 1 motor 16 and moves in cooperation with the outside of the No. 1 screw rod 17.

The limit lifting plate 39 can locate the grinding position of the workpiece 31, thereby ensuring that the grinding rod 32 can penetrate into the inner corner of the workpiece 31 in the later stage, which is convenient for grinding the burrs of the inner corner in the later stage. Conveyor 2 is a double-belt roller conveyor.

[0028] Working principle: When in use, the conveyor 2 conveys the cast workpiece 31 to one side of the truss body 1, and then, driven by the first hydraulic cylinder 6, the mounting plate 8 moves downward together with the supporting plate 7 until the two L-shaped clamping rods 24 are close to the two sides of the workpiece 31. Under the drive and clamping of the two-way telescopic cylinder 26, the two clamping rods 24 clamp the workpiece 31, and then the second hydraulic cylinder 25 drives the movable seat 22 to drive the two-way telescopic cylinder 26 to convey to one end of the guide plate 15, and then the clamped workpiece 31 is stored on the upper end surface of the other side of the guide plate 15 blocked by the L-shaped plate 9 under the guidance of the guide plate 15, and then the above steps are repeated, thereby the telescopic reciprocating mechanism 4 outputs When delivering the workpiece 31, several groups of workpieces 31 can be clamped at one time for transportation, which can greatly improve the subsequent processing efficiency and reduce the wear of the lead screw group of the telescopic reciprocating mechanism 4. When conveying each workpiece 31, the grinding rod 32 can be inserted into the corner inside the workpiece 31, and then driven by the corresponding No. 2 motor 35, the transmission wheel and the synchronous belt 30 drive the two mounting rods 34 on the same side to rotate. Therefore, when transporting the workpiece 31, the burrs at the internal corners of the cast workpiece 31 can be processed. After completion, the dust and waste chips are blown away by the blowing of the air pump 29 and the nozzle 27, thereby improving the quality of subsequent machine tool processing.
