Description

Technical Field

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

[0002] The loading and unloading manipulator of a numerical control machine tool is a Cartesian coordinate robot manipulator used for automatic loading and unloading of a numerical control machine tool, and can realize an automatic control, repetitive programming, multi-functional, multi-degree-of-freedom, and automatic device in which the degrees of freedom of motion form a spatial right-angle relationship. Existing such manipulators usually use a truss as a base and are combined with a numerical control machine tool, and can realize automatic grasping, loading, and unloading of workpieces in all technological processes, which can greatly save labor costs;

[0003] During the processing of a workpiece, different machining processes need to be completed on different machine tools. Since machine tools can be classified into various types according to machining accuracy, machining methods, etc., and their uses are not completely the same, different processes of the workpiece need to be machined on machine tools with different machining processes. The prior art uses a truss as a base for large-range transfer of the workpiece between different machine tools.

[0004] However, when the workpiece is processed on the machine tool responsible for one of the processes, the existing conveying mechanism for loading the workpiece can only perform a single transfer of the processed workpiece. When facing large-range workpiece transfer, 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, burr edges usually remain in the inner corners during the processing of the workpiece, which will affect the use accuracy in subsequent reprocessing. Therefore, we need to improve this. Summary of the Invention

[0029] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0031] As Figures 1 - 9 shown, a truss structure of a numerical control machine tool includes a truss main body 1, a conveyor 2, a shelf board 3, a telescopic reciprocating mechanism 4 and a workpiece 31. The shelf board 3 is arranged outside the truss main body 1. Rail frames 10 are fixedly arranged on both sides of the bottom of the shelf board 3. The telescopic reciprocating mechanism 4 is arranged between the two groups of rail frames 10. A slide seat 5 is arranged outside the telescopic reciprocating mechanism 4, and the slide seat 5 is slidably matched with the two groups of rail frames 10. A first hydraulic cylinder 6 is arranged in the middle of the slide seat 5. A support plate 7 is fixedly arranged at the telescopic end of the first hydraulic cylinder 6. One side of the outer wall of the support plate 7 is provided with a mounting plate 8. A storage mechanism is arranged below the outside of the mounting plate 8. A pushing mechanism is arranged at the upper end of the mounting plate 8. The conveyor 2 is arranged below one side of the truss main body 1;

[0032] The conveyor 2 transports the processed workpiece 31 to the lower part of the support plate 7, and a plurality of workpieces 31 are stored inside the storage mechanism through the clamping of the pushing mechanism;

[0033] As Figure 1 , Figure 2 and Figure 3 shown, the telescopic reciprocating mechanism 4 is composed of structures such as a motor group and a lead screw group, which is a common driving mechanism and will not be elaborated here too much. The conveyor 2 transports the cast workpiece 31 from one side to the truss main body 1, and then clamps and conveys the workpiece 31.

[0034] The storage mechanism includes fixed rods 13 respectively and fixedly arranged on both sides of the outer wall of the mounting plate 8. Hanging plates 14 are fixedly sleeved on the outer sides of the two fixed rods 13. A guiding plate 15 is jointly arranged at the lower ends of the two hanging plates 14. The guiding plate 15 is bent. The side of the guiding plate 15 away from the hanging plate 14 is connected to the storage mechanism;

[0035] As Figure 3 and Figure 4 shown, the hanging plates 14 block the two sides of the upper end of the guiding plate 15, and the guiding plate 15 is installed outside the fixed rods 13 for use. When the workpiece 31 is transferred later, the workpiece 31 can fall onto the lower end surface of the guiding plate 15 for storage.

[0036] The storage mechanism includes an L-shaped plate 9. The L-shaped plate 9 is fixedly arranged on the upper end surface of the side of the guiding plate 15 away from the hanging plate 14. A storage box 20 is installed on one side inside the L-shaped plate 9. First cylinders 19 are respectively and fixedly installed on the upper and lower sides inside the storage box 20. A push plate 12 is jointly arranged at the telescopic ends of the two groups of first cylinders 19;

[0037] As Figure 3 and Figure 4 shown, the L-shaped plate 9 is vertically installed on the upper end surface of one side of the guiding plate 15, and the other side is open, aiming to facilitate the storage of the workpiece 31;

[0038] The first cylinder 19 can drive the push plate 12 to move towards the open end, so that several groups of workpieces 31 can be transferred towards the machine tool and cooperate with the machine tool for subsequent processing operations.

[0039] The pushing mechanism includes a fixed block 36 fixedly arranged on the upper end surface of the mounting plate 8. A second hydraulic cylinder 25 is fixedly arranged inside the fixed block 36. A movable seat 22 is fixedly arranged at the telescopic end of the second hydraulic cylinder 25. The movable seat 22 is slidably matched with the mounting plate 8. A two-way telescopic cylinder 26 is fixedly installed on the lower end surface of the movable seat 22. Clamping members are respectively arranged at both ends of the two-way telescopic cylinder 26.

[0040] The clamping member includes a clamping rod 24 fixedly arranged at one end of the two-way telescopic cylinder 26. The clamping rod 24 is L-shaped;

[0041] As Figure 1 、 Figure 2 and Figure 5 shown, the driving of the second hydraulic cylinder 25 can cause the movable seat 22 to slide outside the mounting plate 8, and then the two clamping rods 24 at the lower end can be driven to transport the workpiece 31 after clamping to one side of the guiding plate 15;

[0042] Driven by the two-way telescopic cylinder 26, the two L-shaped clamping rods 24 can clamp the workpiece 31 conveyed by the conveyor 2.

[0043] A frame base 21 is commonly arranged between two clamping rods 24. In the middle of the interior of the frame base 21, an air pump 29 is fixedly arranged. Above the interior of the air pump 29, a spray head 27 is connected through a connecting pipe 33 installed in a communicating manner. A fixing ring 28 is fixedly sleeved outside the spray head 27. Four connecting rods 37 are arranged on the outside of the fixing ring 28, and the four connecting rods 37 are arranged in an X shape.

[0044] As Figure 5 and Figure 6 shown, the air pump 29 can convey air flow to the spray head 27 through the connecting pipe 33. In the later stage, the spray head 27 can not only blow dust and chips, but also reduce the temperature of the cast workpiece 31.

[0045] An installation rod 34 is rotatably inserted through the interior of the connecting rod 37. Transmission wheels are sleeved on the outside of the installation rod 34 and above the connecting rod 37. Synchronous belts 30 are commonly sleeved on the outside of the two groups of transmission wheels on the same side. At the upper end of one of the installation rods 34 on the same side, a second motor 35 is fixedly installed. The outside of the second motor 35 is connected to the upper end face of the corresponding connecting rod 37 through an L-shaped rod arranged. A grinding rod 32 is fixedly sleeved below the outside of the installation rod 34.

[0046] As Figure 5 and Figure 6 shown, the second motor 35 drives the corresponding installation rod 34 to rotate. Under the transmission connection of the transmission wheels and the synchronous belts 30, the other installation rod 34 also rotates immediately. Thus, the installation rod 34 and the grinding rod 32 can grind at the internal corner of the workpiece 31.

[0047] The use height of the grinding rod 32 can reach deep into the interior of the workpiece 31 through the lifting of the first hydraulic cylinder 6. The grinding rod 32 is used as a grinding rod with a diamond brush.

[0048] Under the connection of the connecting rod 37, the installation rod 34 can be installed and used outside the fixing ring 28.

[0049] A U-shaped frame 11 is fixedly arranged on the outside of the guiding plate 15. A baffle 18 is slidably installed inside the U-shaped frame 11. A first screw rod 17 is rotatably installed inside the U-shaped frame 11, and the first screw rod 17 threadedly penetrates through the interior of the baffle 18. One end of the first screw rod 17 is fixedly installed with a first motor 16, and the first motor 16 is fixedly connected to the U-shaped frame 11.

[0050] As Figure 3 and Figure 4 shown, under the drive of the first motor 16, the baffle 18 moves in cooperation on the outside of the first screw rod 17. When transporting the workpiece 31, it can block one end of the L-shaped plate 9, thereby preventing the workpiece 31 from detaching from one side during storage.

[0051] A chassis 23 is fixedly arranged below one end of the conveyor 2, and a second cylinder 38 is installed inside the chassis 23. A limiting lifting plate 39 is arranged at the telescopic end of the second cylinder 38.

[0052] As Figure 1 , Figure 2 and Figure 7 shown, the chassis 23 facilitates the installation of the second cylinder 38 at the lower end of the conveyor 2. During the process of waiting to clamp the parts, the set second cylinder 38 can lift the current workpiece 31 to be clamped, thereby reducing the contact between the workpieces 31 in the later stage, having the function of blocking and limiting, and the limiting lifting plate 39 can position the grinding position of the workpiece 31, so as to ensure that the later grinding rod 32 can penetrate into the inner corner of the workpiece 31, facilitating the grinding of the burrs at the inner corner in the later stage;

[0053] The conveyor 2 is used as a double-belt roller conveyor device.

[0054] Working principle: When in use, the conveyor 2 transports the cast workpiece 31 to one side of the truss main body 1. Subsequently, under the drive of the first hydraulic cylinder 6, the mounting plate 8 and the support plate 7 move downward together until the two L-shaped clamping rods 24 approach both sides of the workpiece 31. Under the drive and clamping of the double-acting telescopic cylinder 26, the two clamping rods 24 clamp the workpiece 31. Then, the second hydraulic cylinder 25 drives the movable seat 22 to drive the double-acting telescopic cylinder 26 to transport towards one end of the guide plate 15. Immediately, the clamped workpiece 31 is placed 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. Then, repeat the above steps. Thus, when the reciprocating mechanism 4 transports the workpiece 31, several groups of workpieces 31 can be clamped and transported at one time, which can greatly improve the later processing efficiency, and at the same time reduce the wear of the lead screw group of the reciprocating mechanism 4. When transporting each workpiece 31, the grinding rod 32 can penetrate into the inner corner of the workpiece 31. Then, under the drive of the corresponding second motor 35, the transmission wheel and the synchronous belt 30 drive the two mounting rods 34 on the same side to rotate. Thus, when transporting the workpiece 31, the burrs at the inner corner of the cast workpiece 31 can be processed. After completion, through the blowing of the air pump 29 and the nozzle 27, the dust and waste chips are blown away, thereby improving the quality of the later machine tool processing.

[0055] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
