Description

Technical Field

[0001] This utility model relates to the field of machining center technology, and in particular to a clamping device for a vertical machining center. Background Technology

[0002] A vertical machining center is a machining center whose spindle axis is set perpendicular to the worktable. It is mainly suitable for machining complex parts such as plates, discs, molds, and small shells. Vertical machining centers can perform milling, boring, drilling, tapping, and thread cutting operations. When a vertical machining center is machining a workpiece, it is usually necessary to clamp the workpiece to fix its machining position.

[0003] Referring to existing patent publication number CN218363433U, a workpiece clamping device for a vertical machining center includes a machining table with a workpiece clamping groove inside. A workpiece clamping plate is located inside the workpiece clamping groove, and a workpiece clamping platform is fixedly installed at the top of one side of the machining table. This design uses a cylinder to provide the driving power for the connecting crossbar, which, via a first and second rotating support rod, rotatably connects and drives the two clamping blocks closer together or further apart, thus facilitating adjustment of the clamping distance on the workpiece as needed.

[0004] However, in actual use, existing machining centers have relatively simple clamping methods for workpieces. They either rely on manual operation, which is labor-intensive, or on electric operation of components, which is difficult to operate when short-circuited, making them quite troublesome. Therefore, the use of clamping devices lacks flexibility. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vertical machining center clamping device. This invention utilizes a drive mechanism and transmission components constructed between the clamping table and the base. This allows for manual clamping of the workpiece by rotating the clamping table without starting the motor, or automatic clamping by fixing the clamping table when the motor is running. The user can choose between manual or automatic clamping, providing diverse options and greater flexibility.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clamping device for a vertical machining center, comprising:

[0008] The base serves as the fundamental support for the entire clamping device.

[0009] A clamping platform is rotatably connected to the upper part of the base via a support rod, and a limiting assembly is constructed between the clamping platform and the base;

[0010] Each screw is horizontally connected inside the clamping table, and each screw has a threaded sleeve installed on its surface. A clamp is installed on the surface of the threaded sleeve.

[0011] A drive mechanism is mounted on the surface of the base, and a transmission component that cooperates with the drive mechanism is constructed on the lower part of the clamping platform and the surface of the base.

[0012] The present invention is further configured such that the limiting component includes: a telescopic rod, an elastic element, and a limiting groove;

[0013] The telescopic rod is mounted on the surface of the base, the elastic element is mounted on the surface of the telescopic rod, and the limiting groove is formed in the lower part of the clamping table.

[0014] The present invention is further configured such that one end of the telescopic rod is located within a defined groove.

[0015] The present invention is further configured such that the driving mechanism includes: a motor, a drive shaft, and a transmission component 2;

[0016] The motor is mounted on the surface of the base, the drive shaft is connected to the output end of the motor, and the transmission component 2 is mounted on the end of the drive shaft away from the motor.

[0017] The present invention is further configured such that the transmission assembly includes: a rotating component, a first bevel gear, a second bevel gear, a first transmission component, and a third transmission component;

[0018] The rotating component is connected to the lower part of the clamping table. The first bevel gear is mounted on the surface of the screw. The second bevel gear is mounted on the surface of the rotating component. The third transmission component is rotatably connected to the surface of the base. The first transmission component is mounted on one end of the rotating component.

[0019] The present invention is further configured such that the second bevel gear meshes with the first bevel gear, and the third transmission component cooperates with both the first and the second transmission component.

[0020] The present invention is further configured such that a collection frame is installed on the lower part of the base, and a channel is constructed between the clamping platform and the base.

[0021] The beneficial effects of this utility model are as follows: By constructing a drive mechanism and transmission components between the clamping table and the base, this utility model enables manual clamping of the workpiece by rotating the clamping table without starting the motor. When the motor is started, the workpiece can be automatically clamped simply by fixing the clamping table. The operator can choose to clamp the workpiece manually or automatically, providing a variety of options and greater flexibility.

[0022] 1. This vertical machining center clamping device, through the cooperation of a transmission component and a drive mechanism, allows for manual clamping of workpieces by rotating the clamping table without starting the motor. When the motor is started, the workpiece can be automatically clamped simply by fixing the clamping table. The operator can choose to clamp the workpiece manually or automatically, providing a variety of options and flexibility.

[0023] 2. The clamping device of this vertical machining center, by setting a limiting component, allows the operator to press the telescopic rod to disengage it from the limiting groove and compress the elastic element after the workpiece is clamped and during machining or adjustment of the clamping method. This releases the clamping table from its fixation, facilitating operation of the clamping table. At the same time, when one end of the telescopic rod is located in the limiting groove, the clamping table can be fixed, reducing its movement and improving stability. Attached Figure Description

Therefore, they should not be construed as limitations on this patent.

[0031] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting.

[0032] Reference Figures 1 to 3 A vertical machining center clamping device includes: a base 1, serving as the basic support for the entire clamping device, ensuring the stability and load-bearing capacity of the device; a clamping table 2, rotatably connected to the upper part of the base 1 via a support rod 11, allowing the clamping table 2 to rotate within a certain range for easy workpiece clamping and adjustment; a limiting component is constructed between the clamping table 2 and the base 1 to limit the rotation range of the clamping table 2, ensuring the stability and accuracy of the workpiece during machining; screws 5, all horizontally connected inside the clamping table 2, with threaded sleeves 3 mounted on the surface of each screw 5, and clamps 4 mounted on the surface of each threaded sleeve. When the screw 5 rotates, the threaded sleeves 3 drive the clamps 4 to move horizontally, thereby clamping or releasing the workpiece; a drive mechanism is mounted on the surface of the base 1, and a transmission component is constructed on the lower part of the clamping table 2 and the surface of the base 1 to cooperate with the drive mechanism. The drive mechanism provides power to the device, and in cooperation with the transmission component, the drive mechanism drives the screws 5 to rotate, thereby realizing the movement of the clamps 4 and the clamping of the workpiece, enabling step-by-step transfer of work.

[0033] Specifically, refer to Figure 2 The limiting components include: a telescopic rod 12, an elastic element 13, and a limiting groove 14; the telescopic rod 12 is mounted on the surface of the base 1, the elastic element 13 is mounted on the surface of the telescopic rod 12, and the limiting groove 14 is opened in the lower part of the clamping table 2. In this embodiment, the telescopic rod 12 can extend and retract in the vertical direction, and can compress or stretch the elastic element 13 during the extension and retraction, thereby cooperating with the limiting groove 14.

[0034] Furthermore, one end of the telescopic rod 12 is located in the limiting groove 14. With this design, the telescopic rod 12 disengages from the limiting groove 14 and compresses the elastic element 13, thereby releasing the fixation of the clamping table 2 and facilitating the operation of the clamping table 2. Similarly, when one end of the telescopic rod 12 is located in the limiting groove 14, the clamping table 2 can be fixed, reducing the movement of the clamping table 2 and improving stability.

[0035] Specifically, refer to Figure 2 The drive mechanism includes a motor 9, a drive shaft 19, and a transmission component 17. The motor 9 is mounted on the surface of the base 1, the drive shaft 19 is connected to the output end of the motor 9, and the transmission component 17 is mounted on the end of the drive shaft 19 away from the motor 9. In this embodiment, the motor 9 serves as the power source for the entire drive mechanism. It is mounted on the surface of the base 1 to provide a stable driving force for the clamping device. When the motor 9 starts and drives the drive shaft 19 to rotate, the transmission component 17 converts the rotational motion into the linear or rotational motion required by the clamping device.

[0036] Specifically, refer to Figures 2 to 3 The transmission assembly includes: a rotating component 16, a first bevel gear 7, a second bevel gear 15, a first transmission component 8, and a third transmission component 18. The rotating component 16 is connected to the lower part of the clamping table 2. The first bevel gear 7 is mounted on the surface of the screw 5. The second bevel gear 15 is mounted on the surface of the rotating component 16. The third transmission component 18 is rotatably connected to the surface of the base 1. The first transmission component 8 is mounted on one end of the rotating component 16. With this implementation, when the motor 9 is started, the clamping table 2 only needs to be fixed. At this time, the motor 9 drives the second transmission component 17 and the third transmission component 18 to move through the drive shaft 19. The third transmission component 18 synchronously transmits the action to the position of the first transmission component 8, so that the first transmission component 8 can drive the rotating component 16 and the second bevel gear 15 to move.

[0037] Furthermore, bevel gear 2 15 meshes with bevel gear 1 7, and transmission component 3 18 cooperates with transmission component 1 8 and transmission component 2 17. As another implementation method in this embodiment, transmission component 1 8, transmission component 2 17 and transmission component 3 18 can be meshing teeth, so that transmission component 2 17 and transmission component 3 18 will be in a fixed state when the motor 9 is not started, so as to improve the transmission accuracy and stability between the transmission components. When bevel gear 2 15 rotates, it can transmit the action to bevel gear 1 7 and screw 5. At this time, threaded sleeve 3 and clamp 4 can approach each other to clamp and fix the workpiece.

[0038] When clamping the workpiece, without starting the motor 9, the second transmission component 17 and the third transmission component 18 will be in a fixed state. The operator can rotate the clamping table 2, which will drive the first transmission component 8 to rotate under the action of the fixed second transmission component 17 and the third transmission component 18. This will cause the first transmission component 8 to drive the rotating component 16 and the second bevel gear 15 to rotate. The second bevel gear 15 will transmit the action to the first bevel gear 7 and the screw 5. At this time, the threaded sleeve 3 and the clamp 4 can move closer to each other to clamp and fix the workpiece, which can be done manually. When the motor 9 is started, the clamping table 2 only needs to be fixed. At this time, the motor 9 drives the second transmission component 17 and the third transmission component 18 to move through the drive shaft 19. The third transmission component 18 will transmit the action synchronously to the position of the first transmission component 8, which can also transmit the action to the position of the clamp 4, thus realizing the automatic clamping of the workpiece. The operator can choose to clamp the workpiece manually or automatically, providing multiple options.

[0039] Specifically, refer to Figure 2 A collection frame 10 is installed on the lower part of the base 1, and a channel 6 is constructed between the clamping table 2 and the base 1. In this embodiment, metal chips may be generated between the workpiece and the tool during the processing, and the collection frame 10 can effectively collect these chips through the channel 6.

[0040] Working Principle: When using this invention, the workpiece is first placed on the clamping table 2. When clamping the workpiece, without starting the motor 9, the transmission components 17 and 18 are fixed. The operator can rotate the clamping table 2, which will cause the transmission component 8 to rotate under the action of the fixed transmission components 17 and 18. This causes the transmission component 8 to drive the rotating component 16 and the bevel gear 15 to rotate. The bevel gear 15 transmits the motion to the bevel gear 7 and the screw 5. At this time, the threaded sleeve 3 and the clamp 4 can move closer together to clamp and fix the workpiece, allowing for manual clamping. When starting the motor 9, simply fix the clamping table 2; the motor will then start. 9. Driven by the drive shaft 19, the transmission components 17 and 18 move. The transmission component 18 transmits the action synchronously to the position of the transmission component 8, which in turn transmits the action to the position of the clamp 4, thus achieving automatic clamping of the workpiece. The operator can choose to clamp the workpiece manually or automatically, providing various options and flexibility. When processing or adjusting the clamping method after clamping the workpiece, the operator can press the telescopic rod 12 to disengage it from the limiting groove 14 and compress the elastic element 13, thereby releasing the fixation of the clamping table 2 and facilitating the operation of the clamping table 2. Similarly, when one end of the telescopic rod 12 is located in the limiting groove 14, the clamping table 2 can be fixed, reducing the movement of the clamping table 2 and improving stability.

[0041] 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.
