Description

Technical Field

[0002] The process of machine tool processing products involves collecting and transferring workpieces, and a material receiving mechanism is usually required to achieve this function. For example, an existing dual-spindle machine tool uses two sets of spindles and tool holders to process products in turn, and the material receiving mechanism includes a flip hopper, a conveyor belt, etc. After the product processing is completed, the corresponding spindle unloads the product and makes it fall into the hopper. The hopper flips and dumps the product and transports it to the receiving box via a conveyor belt. The material receiving mechanism is relatively complex, costly, and has a high probability of damage to the transported workpiece. Therefore, there is room for improvement in the material receiving mechanism of existing machine tools. Utility Model Content

[0029] Refer to the appendix Figure 1, shown is a material receiving mechanism of a machine tool, the mechanism includes a base 1, used to connect with the corresponding machine tool so that the material receiving mechanism is installed on the machine tool; a manipulator 2, used to pick up and place products processed by the machine tool, which is installed on the base 1; a drive control component 3, which is connected to the manipulator 2 to control the movement of the manipulator 2; a material trough 4, used to convey the products taken by the manipulator 2, which is inclined downward from the head end to the tail end, and the head end of the material trough 4 corresponds to the bottom of the movement path of the manipulator 2, and the tail end of the material trough 4 forms a notch 43.

[0030] The base 1 is usually made of metal and can be connected to the machine tool through bolts and other parts. For example, the base 1 can be set to a Z-shaped structure, with a longitudinal main body plate in the middle, one side of the main body plate is connected to a horizontally laid support plate at the bottom, and the other side of the main body plate is connected to a horizontally laid support plate at the top. A plurality of screw holes are set on the support plate, and screws are installed at the screw holes to connect the support plate to the machine tool to achieve the fixation of the base 1. The drive control component 3 and the manipulator 2 are installed on the support plate. The manipulator 2 is controlled by the drive control component 3 to move back and forth. The manipulator 2 moves to one end of the stroke to remove the processed workpiece, and then returns to the top of the material trough 4 to release the workpiece so that it falls into the material trough 4. The inclined slope of the material trough 4 allows the workpiece to slide out of the slot 43 and reach the receiving box of the machine tool.

[0031] In some embodiments, the drive control assembly 3 includes a cylinder 30 and a linear slide 31 installed on the base 1, the manipulator 2 is installed on the linear slide 31, and the output end of the cylinder 30 is connected to the manipulator 2 in a transmission manner to control its movement along the linear slide 31. For example, the drive control assembly 3 is installed on the support plate on the upper part of the base 1, and the cylinder 30 controls the manipulator 2 to move back and forth along the linear slide 31. The manipulator 2 moves away from the material trough 4 to the spindle on the machine tool, removes the processed workpiece, and then moves toward the material trough 4. Above the material trough 4, the manipulator 2 puts down the workpiece so that it falls into the material trough 4, and then slides along the material trough 4 to the receiving box of the machine tool.

[0032] Among them, the manipulator 2 can use a pneumatic gripper 20, which has a pneumatic pipeline 21, and the opening and closing of the pneumatic gripper 20 is controlled by the pneumatic pipeline 21. The pneumatic pipeline 21 can be configured with a drag chain 22, and the pneumatic pipeline 21 moves with the pneumatic gripper 20 under the protection of the drag chain 22.

[0033] Specifically, a base plate 23 is mounted on the linear guide rail 31, and the base plate 23 is connected to the output end of the cylinder 30. The pneumatic gripper 20 is fixed on the base plate 23 and is biased to one side of the base 1. The material trough 4 is arranged on one side of the base 1 so that its head end is connected to the bottom of the pneumatic gripper 20. The base plate 23 is controlled by the cylinder 30 to move along the linear guide rail 31. The pneumatic gripper 20 and the material trough 4 are both arranged on the same side of the base 1. When the pneumatic gripper 20 moves, its movement path passes above the head end of the material trough 4 so as to place the clamped workpiece into the material trough 4 below.

[0034] Generally, the trough 4 includes a bottom plate 40 and side plates 41 installed on both sides of the bottom plate 40. The workpiece slides along the bottom plate 40, and the side plates 41 on both sides produce a blocking and protective effect to prevent the workpiece from falling midway. Furthermore, an end plate 42 can be provided at the head end of the trough 4 to strengthen the protection of the workpiece. Preferably, a buffer pad 44 is laid at the bottom of the trough 4. The buffer pad 44 can be made of rubber and laid on the surface of the bottom plate 40. When the workpiece falls, the buffer pad 44 produces a buffering and protective effect to reduce the probability of damage to the workpiece by collision.

[0035] See attached Figures 2-3 , provides a dual-spindle machine tool, including a frame 5, on which a processing assembly and a material receiving box are installed, the processing assembly includes a first spindle assembly and a first tool holder that are adapted to each other, and a second spindle assembly 7 and a second tool holder, the frame is installed with a material receiving mechanism as described in any of the preceding items, the manipulator 2 of the material receiving mechanism corresponds to the second spindle assembly 7, and the material trough 4 of the material receiving mechanism corresponds to the material receiving box.

[0036] When the dual-spindle machine tool is working, the first spindle assembly grabs the workpiece, the first tool holder processes it, and then the second spindle assembly 7 obtains the workpiece from the first spindle assembly, the second tool holder processes the workpiece, and then the manipulator 2 of the material receiving mechanism removes the workpiece from the second spindle assembly and sends it to the material trough 4, sliding along the material trough 4 through the notch 43 to reach the material receiving box.

[0037] Usually, the processing assembly is installed in a relatively independent area of the machine tool, so that the processing assembly and the material receiving mechanism are isolated, so as to prevent the debris of the processing assembly from flying into the material receiving mechanism during operation, thereby affecting its service life. For example, the machine tool has at least one column, the processing assembly and the material receiving mechanism are located on both sides of the column, the column is provided with a window, the window is equipped with an openable hinge cover 6, and the pneumatic clamp 20 of the manipulator 2 moves to achieve cooperation with the second spindle assembly through the window.

[0038] The hinge cover 6 can adopt a driving structure such as a cylinder 30 to control the opening and closing action. When the processing component is working, the hinge cover 6 is in a closed state, shielding and protecting the feeding mechanism. After the processing is completed, the hinge cover 6 is opened, and the manipulator 2 of the feeding mechanism enters the area where the processing component is located from the window, removes the workpiece on the second spindle component 7, and then withdraws from the window.

[0039] In summary, the improved feeding mechanism obtains the processed workpiece through the manipulator 2, places it in the material chute 4, and makes the workpiece slide out by means of the inclined slope of the material chute 4. The overall structural composition is relatively simple, which is beneficial to reducing costs and can also effectively reduce the probability of the workpiece being damaged.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes, combinations, and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
