Description

Technical Field

[0001] This utility model relates to the technical field of workpiece processing devices, and in particular to a turnover mechanism for workpiece cutting. Background Technology

[0002] In the process of cutting and processing workpieces, tools such as linear modules are first used to supply the workpieces so that they can be transported to the cutting process. After the workpieces arrive at the cutting process, they are usually picked up by a turret and finally cut by a cutting machine.

[0003] However, existing linear modules and other devices used for workpiece transport can only achieve unidirectional transmission and cannot rotate the workpiece. When the workpiece is transported to the cutting station, its position may not correspond to the turret's suction component, making it difficult for the turret to pick up the workpiece. This has a certain impact on the subsequent workpiece cutting work. Therefore, it is necessary to design an auxiliary turnover device that can transport the workpiece to the cutting station and rotate the workpiece to a suitable angle for the turret to pick up the workpiece. Utility Model Content

[0004] To solve the above problems, this utility model provides a turnover mechanism for workpiece cutting.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a turnover mechanism for workpiece cutting, including a mounting plate, a mounting block and a slide rail fixed on the top of the mounting plate, a movable plate slidably mounted on the slide rail, a mounting frame fixed on the top of the movable plate, a rotating shaft rotatably connected to the mounting frame and passing through the mounting frame, a rotating component for driving the rotating shaft to rotate on the mounting frame, a mounting plate fixed on the top of the rotating shaft, a receiving plate detachably connected to the top of the mounting plate, and a translation component for driving the movable plate to slide back and forth along the slide rail on the mounting block.

[0006] By adopting the above technical solution, the translation component can drive the movable plate to slide back and forth along the slide rail, thereby enabling the mounting frame, rotating shaft, mounting plate and receiving plate to move synchronously. The rotation component can drive the rotating shaft, mounting plate and receiving plate to rotate synchronously, thereby enabling the workpiece to not only translate but also rotate, so that the workpiece can be rotated to a suitable angle for the brick tower to pick up, which facilitates the subsequent cutting work of the workpiece.

[0007] Furthermore, the rotating assembly includes connecting rods fixed to the top plate of the mounting bracket and a rotating motor fixed to the lower end of the connecting rods. The connecting rods are provided in four and arranged in a rectangular array. A rectangular through hole is provided through the movable plate for the four connecting rods to pass through simultaneously. A translational movable hole is provided through the mounting plate for the rotating motor to move.

[0008] By adopting the above technical solution, the rotating motor drives the rotating shaft to rotate after it starts working, thereby making the mounting plate, the receiving plate, and the workpiece on the receiving plate rotate synchronously so that the workpiece rotates to a suitable angle for the brick tower to pick up.

[0009] Furthermore, the rotating shaft is connected to the output shaft of the rotating motor via a coupling.

[0010] Furthermore, a slider that slides with the slide rail is fixed to the bottom of the movable plate, and a U-shaped groove communicating with the side wall of the mounting block near the mounting frame is provided through the mounting block. One side of the movable plate is located in the U-shaped groove. The translation assembly includes a translation motor fixed to the top of the mounting block and a cam fixed to the output end of the translation motor. The output shaft of the translation motor is located near the edge of the cam. A transmission hole with a width greater than the outer diameter of the cam is provided through the movable plate, and the side of the cam away from the output end of the translation motor abuts against the inner wall of the transmission hole.

[0011] By adopting the above technical solution, after the translation motor works, it drives the cam to rotate. Since the side of the cam away from the output end of the translation motor abuts against the transmission hole on the movable plate, the movable plate can slide back and forth along the length of the slide rail while the cam rotates, thereby allowing the workpiece on the receiving plate to be transported from the previous process to the processing process.

[0012] Furthermore, the mounting block is provided with a clearance groove communicating with the U-shaped groove. There are two clearance grooves arranged symmetrically, and the thickness of the clearance groove is greater than the thickness of the movable plate.

[0013] By adopting the above technical solution and setting the clearance groove, the situation where the movable plate collides with the mounting block during the movement is avoided.

[0014] Furthermore, a bracket is fixed on the top of the mounting plate at a position away from the mounting block, and a proximity switch for detecting the position of the mounting bracket is fixed on the bracket.

[0015] By adopting the above technical solution, the proximity switch can detect the position of the mounting bracket, so that the control system of the workpiece cutting turnover mechanism can control the operation of the translation motor.

[0016] Furthermore, the top of the receiving plate is provided with multiple sets of air intakes evenly distributed about the axis of rotation, and the center of the top of the receiving plate is provided with an air inlet that is connected to an external inflation system via a hose. The inside of the receiving plate is provided with a connecting channel for connecting the air inlet to the multiple sets of air intakes.

[0017] By adopting the above technical solution, the external inflation system draws air from the air inlet to a negative pressure through a hose. Under the action of the connecting channel, the air inlet sucks up the workpiece that was transported to the receiving plate in the previous process, ensuring the stability of the workpiece on the receiving plate during the operation of the rotating motor and the rotation of the receiving plate.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In this application, the translation component can drive the movable plate to slide back and forth along the slide rail, thereby enabling the mounting frame, rotating shaft, mounting plate and receiving plate to move synchronously. The rotation component can drive the rotating shaft, mounting plate and receiving plate to rotate synchronously, thereby enabling the workpiece to not only translate but also rotate, so that the workpiece can be rotated to a suitable angle for the brick tower to pick up, which facilitates the subsequent cutting work of the workpiece.

[0020] 2. In this application, the external inflation system draws air from the air inlet to a negative pressure through a hose. With the help of the connecting channel, the air inlet sucks up the workpiece that was transported to the receiving plate in the previous process, ensuring the stability of the workpiece on the receiving plate during the operation of the rotating motor and the rotation of the receiving plate.

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-3 As shown in the embodiment of this application, a turnover mechanism for workpiece cutting is disclosed, including a mounting plate 1, a mounting block 2 and a slide rail 11 fixed on the top of the mounting plate 1, a movable plate 3 slidably mounted on the slide rail 11, a mounting frame 4 fixed on the top of the movable plate 3, a rotating shaft 41 rotatably connected to the mounting frame 4 through the mounting frame 4, a rotating component 5 for driving the rotating shaft 41 to rotate on the mounting frame 4, a mounting plate 411 fixed on the top of the rotating shaft 41, a receiving plate 6 detachably connected to the top of the mounting plate 411, and a translation component 7 for driving the movable plate 3 to slide back and forth along the slide rail 11 on the mounting block 2.

[0027] The translation component 7 can drive the movable plate 3 to slide back and forth along the slide rail 11, thereby making the mounting frame 4, the rotating shaft 41, the mounting plate 411 and the receiving plate 6 move synchronously. The rotation component 5 can drive the rotating shaft 41, the mounting plate 411 and the receiving plate 6 to rotate synchronously, so that the workpiece can not only translate but also rotate, so that the workpiece can be rotated to a suitable angle for the brick tower to pick up, which facilitates the subsequent cutting work of the workpiece.

[0028] The rotating assembly 5 includes connecting rods 51 fixed to the top plate of the mounting bracket 4 and a rotating motor 52 fixed to the lower end of the connecting rods 51 (the rotating shaft 41 and the output shaft of the rotating motor 52 are connected by a coupling 9). Four connecting rods 51 are arranged in a rectangular array. A rectangular through hole 31 is provided through the movable plate 3 to allow all four connecting rods 51 to pass through simultaneously. A translational movable hole 12 is provided through the mounting plate 1 to allow the rotating motor 52 to move. After the rotating motor 52 operates, it drives the rotating shaft 41 to rotate, thereby causing the mounting plate 411, the receiving plate 6, and the workpiece on the receiving plate 6 to rotate synchronously, so that the workpiece rotates to an angle suitable for the brick tower to pick up.

[0029] The bottom of the movable plate 3 is fixed with a slider 32 that slides with the slide rail 11. A U-shaped groove 21 is provided through the mounting block 2, which communicates with the side wall of the mounting block 2 near the mounting frame 4. One side of the movable plate 3 is located in the U-shaped groove 21. The translation component 7 includes a translation motor 71 fixed to the top of the mounting block 2 and a cam 72 fixed to the output end of the translation motor 71. The output shaft of the translation motor 71 is located near the edge of the cam 72. A transmission hole 33 with a width greater than the outer diameter of the cam 72 is provided through the movable plate 3. The side of the cam 72 away from the output end of the translation motor 71 abuts against the inner wall of the transmission hole 33.

[0030] After the translation motor 71 starts working, it drives the cam 72 to rotate. Since the side of the cam 72 away from the output end of the translation motor 71 abuts against the transmission hole 33 on the movable plate 3, the movable plate 3 can slide back and forth along the length direction of the slide rail 11 while the cam 72 rotates, so that the workpiece on the receiving plate 6 is transported from the previous process to the processing process.

[0031] To prevent the movable plate 3 from colliding with the mounting block 2 during movement, the mounting block 2 is provided with two clearance grooves 22 that communicate with the U-shaped groove 21. The clearance grooves 22 are provided and symmetrically arranged, and the thickness of the clearance grooves 22 is greater than the thickness of the movable plate 3. A bracket 8 is fixed on the top of the mounting plate 1 away from the mounting block 2. A proximity switch 81 for detecting the position of the mounting frame 4 is fixed on the bracket 8. The proximity switch 81 can detect the position of the mounting frame 4 so that the control system of the workpiece cutting turnover mechanism can control the operation of the translation motor 71. In other embodiments, to facilitate the control system of the workpiece cutting turnover mechanism to control the operation of the rotation motor 52 according to the position of the workpiece, a position sensor 42 for monitoring the position of the receiving plate 6 can be provided on the mounting frame 4.

[0032] The top of the receiving plate 6 is provided with multiple sets of air inlets 61 evenly distributed about the axis of the rotating shaft 41. The center of the top of the receiving plate 6 is provided with an air inlet 62 that is connected to an external inflation system via a hose. The inside of the receiving plate 6 is provided with a connecting channel (not shown in the figure) for connecting the air inlet 62 to the multiple sets of air inlets 61.

[0033] The external inflation system draws air from the air inlet 62 to a negative pressure via a hose. Through the connecting channel, the suction port 61 draws in the workpiece delivered to the receiving tray 6 in the previous process, ensuring the stability of the workpiece on the receiving tray 6 during the operation of the rotating motor 52 and the rotation of the receiving tray 6, thus reducing the probability of the workpiece being thrown out. In other embodiments, to prevent the hose from twisting during the rotation of the receiving tray 6, a rigid connecting pipe can be fixed to one end of the hose connected to the receiving tray 6. The rigid connecting pipe is rotatably connected to the connecting hole at the center of the top of the receiving tray 6 via a rotary shaft seal (the rotary shaft seal is a conventional design in the prior art, capable of maintaining a tight seal between the rigid connecting pipe and the connecting hole at the center of the top of the receiving tray 6).

[0034] The working principle of the workpiece cutting turnover mechanism in this embodiment is as follows: the translation component 7 can drive the movable plate 3 to slide back and forth along the slide rail 11, so that the mounting frame 4, the rotating shaft 41, the mounting plate 411 and the receiving plate 6 move synchronously. The rotation component 5 can drive the rotating shaft 41, the mounting plate 411 and the receiving plate 6 to rotate synchronously, so that the workpiece can not only translate but also rotate, so that the workpiece can be rotated to a suitable angle for the brick tower to pick up, which facilitates the subsequent cutting work of the workpiece.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
