Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a transmission fixing plate for a servo CNC punching machine. Background Technology

[0002] In the assembly and use of servo CNC punch presses, the stability of the transmission system directly depends on the installation accuracy of the transmission fixing plate. As a key structure connecting the punch press frame and transmission components (such as servo motors and gearboxes), it must simultaneously meet the requirements of frame connection robustness and transmission component installation precision. Traditional transmission fixing plates are mostly one-piece cast iron or steel structures. The fixing holes for connecting to the punch press frame and the mounting positions for bearing transmission components are all preset fixed positions, and the dimensions and spacing of the fixing holes and mounting positions cannot be adjusted after machining.

[0003] In actual production, this design has significant limitations: due to differences in design standards, the position and diameter of the fixing slots used to connect the fixing plate on the frame often deviate between different models of servo CNC punch presses; even for punch presses of the same model, the distribution of fixing slots on different batches of frames may have slight offsets due to factors such as welding deformation and machining errors during manufacturing. Because the position of the traditional fixing plate is not adjustable, if the fixing holes cannot be aligned with the fixing slots on the frame, it is necessary to forcibly adapt them by grinding and enlarging the holes and adding shims, which not only damages the structural strength of the fixing plate but may also lead to loosening of the connection and affect the transmission stability. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a transmission fixing plate for a servo CNC punching machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A transmission fixing plate for a servo CNC punch press includes a fixing plate body, which is composed of a back plate and a front plate. The back plate and the front plate are respectively provided with a movable opening and a movable groove. The back plate and the front plate are each provided with a rotating chamber and a transmission chamber. A screw extending into the transmission chamber is rotatably provided in the rotating chamber. A first gear is rotatably provided in the transmission chamber. The screw is connected to the first gear through a transmission mechanism. A movable frame extending into the movable opening and the movable groove is threaded onto the screw. The front plate is provided with a hidden groove. A drag frame extending into the transmission chamber is provided in the hidden groove. The drag frame is connected to the first gear through a snap-fit ​​mechanism.

[0007] Preferably, the transmission mechanism includes a second gear fixedly mounted on the screw, the second gear meshing with the first gear.

[0008] Preferably, the locking mechanism includes a locking block fixedly mounted on the towing frame, and the first gear is provided with a locking hole corresponding to the locking block.

[0009] Preferably, the movable frame on the back plate has a fixing hole, and the movable frame on the front plate has a threaded groove.

[0010] Preferably, the front panel is provided with multiple anti-blocking holes, and the front panel and the back panel are provided with perforations on their corresponding surfaces.

[0011] Preferably, both the first gear and the second gear are bevel gears, and both the snap-fit ​​block and the snap-fit ​​hole are hexagonal.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the screw and gear transmission structure in the rotating chamber and transmission chamber, the moving frame can be adjusted in position within the movable opening and movable slot, so that the fixing holes on the back plate can be adapted to the fixing slots at different positions on the punch press frame, and the threaded grooves on the front plate can be adapted to the fixing holes with different distributions on the base of the transmission component. There is no need to customize multiple specifications of fixing plates, which effectively reduces the dependence on the precision of the mounting position of the frame and transmission component and improves the versatility of the components.

[0014] 2. The anti-blocking design on the front panel provides ample operating space for operators, facilitating the adjustment and fixation of the movable frame in the movable slot; the tow frame is connected to the first gear through a snap-fit ​​mechanism, and the screw can be driven to rotate simply by moving and rotating the tow frame, realizing the rapid adjustment of the movable frame, greatly shortening the assembly time and improving the installation efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A transmission fixing plate for a servo CNC punch press includes a fixing plate body, which is composed of a back plate 1 and a front plate 2. The back plate 1 and the front plate 2 are fixedly connected. The back plate 1 is connected to the frame inside the servo CNC punch press. The front plate 2 is a major component of the transmission system (such as a servo motor and a gearbox).

[0023] The back panel 1 and the front panel 2 are respectively provided with movable openings 3 and movable slots 4. There are four movable openings 3 and four movable slots 4, which are evenly distributed around the perimeter. Figure 1 In the state shown, the movable port 3 and the movable slot 4 are designed in an alternating manner. The front panel 2 is provided with multiple anti-blocking ports 5, which are designed to facilitate the operation of the movable slot 4 by the operator.

[0024] Both the back panel 1 and the front panel 2 are provided with a rotating chamber 7 and a transmission chamber 11. A screw 8 extending into the transmission chamber 11 is rotatably provided in the rotating chamber 7. A first gear 12 is rotatably provided in the transmission chamber 11. The screw 8 is connected to the first gear 12 through a transmission mechanism. A movable frame 9 extending into the movable opening 3 and the movable groove 4 is threaded on the screw 8. The movable frame 9 on the back panel 1 is provided with a fixing hole 10. The movable frame 9 on the front panel 2 is provided with a threaded groove 18.

[0025] The front panel 2 is provided with a hidden groove 6, and a towing frame 14 extending into the transmission chamber 11 is provided in the hidden groove 6. The towing frame 14 is movable and rotatable, and the towing frame 14 is connected to the first gear 12 through a snap-fit ​​mechanism.

[0026] The transmission mechanism includes a second gear 13 fixedly mounted on the screw 8, which meshes with the first gear 12. Both the first gear 12 and the second gear 13 are bevel gears. The locking block 15 and the locking hole 16 are both hexagonal. Once the towing frame 14 moves, it can drive the locking block 15 to move. The towing frame 14 is provided with two locking blocks 15, and only one locking block 15 can enter the corresponding locking hole 16 at a time.

[0027] The locking mechanism includes a locking block 15 fixedly mounted on the drag frame 14. The first gear 12 has a locking hole 16 corresponding to the locking block 15. A through hole 17 is provided on the surface of the front panel 2 corresponding to the back panel 1. The through hole 17 is larger than the locking block 15 to facilitate the movement of the locking block 15.

[0028] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0029] When this utility model is in use, the back plate 1 and the front plate 2 are welded together. The back plate 1 is fixed to the main frame or base of the punch press, and the main components of the transmission system (such as servo motor and gearbox) are fixed to the front plate 2.

[0030] After the towing frame 14 moves, the locking block 15 set on it can move, and only one locking block 15 is in one locking hole 16 at any given time.

[0031] The movement of the components inside the back plate 1: Keep the drag frame 14 stationary and the snap-fit ​​block 15 in the snap-fit ​​hole 16. Rotating the drag frame 14 will cause it to drive the first gear 12 to rotate. The first gear 12, in conjunction with the second gear 13, will drive the screw 8 to rotate. When the screw 8 rotates, the moving frame 9 moves within the movable opening 3. The four moving frames 9 drive the fixing holes 10 to move and spread or move closer to each other, thereby corresponding to the fixing grooves (threads) on the main frame or base of the punch press. Finally, the fixing bolt assembly passes through the fixing hole 10 and connects to the fixing grooves (threads) on the main frame or base of the punch press. At this time, the fixed installation of the back plate 1 and the front panel 2 is achieved.

[0032] The movement of the components inside the front panel 2: Pulling the drag frame 14 causes the locking block 15 to be in the locking hole 16. Then, rotating the drag frame 14 causes the first gear 12 to rotate. The first gear 12, in conjunction with the second gear 13, can drive the screw 8 to rotate. When the screw 8 rotates, the moving frame 9 moves in the movable opening 3. The four moving frames 9 drive the threaded groove 18 to move and spread or move closer to correspond to the fixing holes on the base of the main components of the transmission system (such as servo motors and gearboxes). Then, the fixing bolt passes through the fixing hole and is threadedly connected to the threaded groove 18 on the moving frame 9.

[0033] At this point, the connection between the back plate 1 and the front plate 2 and the main frame or base of the punch press is completed, and the connection between the main components of the transmission system (such as the servo motor and the gearbox) and the front plate 2 is completed.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
