Description

Technical Field

[0001] The utility model belongs to the technical field of material receiving devices, and particularly relates to a material receiving device for machine tool processed parts. Background Art

[0002] During the process of processing workpieces, the longitudinal cutting machine operates continuously, and the feeding, production processing, and receiving of processed workpieces of the machine tool are all completed without stopping the machine tool. Therefore, the device for receiving processed workpieces is crucial for improving production efficiency.

[0003] Currently, for the material receiving method of micro-precision workpieces, usually, the main shaft clamps the workpiece and moves it to the position of the material receiving box, then releases the chuck, and at the same time, inflates the inner cavity of the main shaft, and uses the gas to blow out the workpiece. However, this technology has several defects: 1. When using the method of blowing air from the back of the main shaft, the gas will be lost when flowing in the main shaft cavity, and there is a risk that the workpiece will get stuck at the chuck position and cannot fall. 2. The material receiving box is usually installed inside the machine tool, and there is a risk that the waste chips generated during the machining process of the machine tool will fall into the material receiving box, resulting in scratches on the surface of the workpiece. 3. After the material receiving box is full, subsequent classification work of workpieces and waste chips is also required, increasing the complexity of subsequent processing. To sum up, in the process of receiving micro-precision workpieces in the prior art, there is a risk that the workpiece cannot be completely blown out from the main shaft cavity, as well as other operational inconveniences. For this reason, a material receiving device for machine tool processed parts is proposed. Summary of the Utility Model

Detailed implementation manners

[0026] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] The following describes the specific implementation of the present utility model in detail in conjunction with specific embodiments.

[0028] As Figures 1-3 shown, a workpiece receiving device for a machine tool workpiece provided by an embodiment of the present utility model includes a workpiece 3 for receiving, which is used to suck the processed workpiece 7, and further includes an intake pipe 2, a lubrication structure, a transfer pipe 6, an equipment main shaft and clamping system 8, an external workpiece receiving box 9, an air source system 10, a transmission pipe 12 and an air pipe 13. The lubrication structure includes an oil inlet pipe 4 and a cutting oil supply system 11.

[0029] The workpiece 3 for receiving is fixed inside the longitudinal cutting machine through a bracket 5, and the center height of the installation of the workpiece 3 for receiving is the same as the center height of the equipment main shaft and clamping system 8.

[0030] One end of the intake pipe 2 is connected to the workpiece 3 for receiving, and the other end is connected to the air source system 10 through the air pipe 13 to provide a high-speed flowing gas to generate suction.

[0031] One end of the oil inlet pipe 4 is connected to the workpiece 3 for receiving, and the other end is connected to the cutting oil supply system 11.

[0032] One end of the transfer pipe 6 is connected to the workpiece 3 for receiving, and the other end is connected to the external workpiece receiving box 9 through the transmission pipe 12; it is used to transfer the processed workpiece.

[0033] The equipment main shaft and clamping system 8 is used to clamp and transport the workpiece 7 during the machine tool processing, and release the chuck after the processing is completed to make the workpiece 7 in a free state.

[0034] The external workpiece receiving box 9 is used to collect and store the processed workpiece 7.

[0035] The air source system 10 is used to provide gas to generate suction.

[0036] The cutting oil supply system 11 is used to provide cutting oil for the transfer pipe 6.

[0037] In the embodiment of the present utility model, the fluid is not limited to gas and can also be liquid.

[0038] This device adopts the ejector effect. By providing high-speed flowing gas through the air supply port of the workpiece receiving part 3, a vacuum area is formed at the material receiving end, thereby sucking the tiny precision workpiece 7 into the cavity interior.

[0039] The ejector effect is a phenomenon in which a high-speed air flow drives a low-speed air flow to move forward together. When the fluid flows at high speed, due to its faster speed than the surrounding fluid, it drives the surrounding fluid to flow together. The change in pressure around the high-speed fluid has a guiding effect on the surrounding fluid.

[0040] The working process of the device is specifically as follows: The equipment spindle and clamping system 8 clamp and transport the workpiece during the machining process of the machine tool; when the machine tool finishes machining the workpiece 7, the equipment spindle and clamping system 8 move to the position of the workpiece receiving part 3 and release the fixation of the workpiece 7. At this time, the workpiece 7 is in a free state. At the same time, the air source system 10 supplies air to the air pipe 13, and the workpiece receiving part 3 generates suction at its material receiving end, thereby sucking the workpiece 7 in the free state into the transfer pipeline 6. The workpiece 7 passes through the transfer pipeline 6 and enters the external material receiving box 9 through the transmission pipeline 12, realizing fully automated material collection.

[0041] In order to prevent the workpiece 7 from getting stuck in the transfer pipeline 6, at the same time, the cutting oil supply system 11 supplies an appropriate amount of cutting oil into the oil supply pipeline 4 to lubricate the transfer pipeline 6, facilitating the passage of the workpiece 7 and its transfer to the external material receiving box 9.

[0042] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present utility model, the equipment spindle and clamping system 8 includes:

[0043] A spindle, which is used to rotate and clamp the workpiece 7 during the machining process of the machine tool;

[0044] A chuck, which is installed at the end of the spindle and is used to clamp the workpiece 7 to ensure its stability during the machining process;

[0045] A spindle cylinder, which is used to drive the chuck at the end of the spindle to loosen or clamp.

[0046] In the embodiment of the present utility model, the equipment spindle and clamping system 8 is connected to the air source system 10 through the air pipe 13, and the air source system 10 provides the necessary air source for it.

[0047] After machining is completed, the spindle cylinder moves, driving the chuck at the end of the spindle to loosen, so that the workpiece 7 is in a free state, facilitating its subsequent suction into the transfer pipeline 6 by the suction force generated by the workpiece receiving part 3. Each component of the equipment spindle and clamping system 8 (not shown in the figure) is prior art and will not be elaborated here.

[0048] The working principle of the present utility model is as follows:

[0049] For the material receiving device for machine tool processed parts, during operation, the equipment spindle and clamping system 8 clamp and transport the workpiece during the machining process of the machine tool; the cutting oil supply system 11 feeds an appropriate amount of cutting oil into the oil supply pipeline 4 to lubricate the conveying pipeline 6, facilitating the passage of the workpiece 7 and conveying it to the external material receiving box 9. When the machine tool finishes machining the workpiece 7, the spindle moves to the position of the material receiving workpiece 3. At this time, the spindle cylinder moves, driving the chuck at the end of the spindle to loosen, and the workpiece 7 is in a free state. Meanwhile, the air source system 10 supplies air to the air pipe 13, and the material receiving workpiece 3 generates suction at its material receiving end, thereby sucking the workpiece 7 in a free state into the conveying pipeline 6. The workpiece 7 passes through the conveying pipeline 6 and enters the external material receiving box 9 through the transmission pipeline 12, realizing fully automated material collection.

[0050] The above is only the preferred embodiment of the present utility model. It should be noted that for those skilled in the art, without departing from the concept of the present utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicability of the patent.
