Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and in particular to a mandrel milling clamping device. Background Technology

[0002] In the field of machining, mandrels are widely used as key components in industries such as automobiles, aerospace, and machine tool manufacturing. The quality of their milling and square machining directly affects the overall performance of the equipment.

[0003] Most existing mandrel clamping devices employ a single clamping method, which struggles to ensure stable fixation from all angles when dealing with mandrels of complex shapes or requiring high precision. This leads to mandrel displacement and vibration during machining, resulting in milling dimensional deviations and substandard surface roughness. Furthermore, traditional clamping devices often cannot quickly adapt to different mandrel lengths, requiring frequent fixture changes that not only increase production costs but also significantly reduce production efficiency. Therefore, we propose a mandrel milling clamping device to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a mandrel milling clamping device. By placing the mandrel into the lower clamping seat slot and making it contact with the positioning plate for initial positioning, the hydraulic cylinder is activated to drive the drive plate and clamping plate to clamp the mandrel horizontally. When the drive plate moves, it drives the upper and lower clamping seats to clamp the mandrel vertically through the crossbar and hinge rod. The position of the clamping plate can also be adjusted by rotating the knob and drive screw to accommodate mandrels of different lengths, thus realizing the horizontal and vertical clamping and fixing of the mandrel and the clamping of mandrels of different lengths.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mandrel milling clamping device includes a worktable, a mounting base fixedly installed on the top of the worktable, a lower clamping base fixedly installed on the top of the mounting base, a positioning plate fixedly installed on the top of the mounting base, an upper clamping base provided above the lower clamping base, multiple placement slots are provided on the sides of the upper and lower clamping bases that are close to each other, and a mandrel is placed in the placement slot on the lower clamping base. A fixing plate is fixedly installed on the top of the worktable, two T-shaped guide rods are fixedly installed on the top of the fixing plate, drive seats are slidably sleeved on the T-shaped guide rods, and the upper clamping base is fixedly installed on the bottom of the two drive seats. A drive plate is slidably installed on the top of the worktable, and a clamping plate for fixing the mandrel is provided on one side of the drive plate.

[0006] By adopting the above technical solution, the mandrel is initially positioned by placing it in the lower clamping seat slot and contacting the positioning plate. The hydraulic cylinder is activated to drive the drive plate and clamping plate to clamp the mandrel horizontally. When the drive plate moves, it drives the upper and lower clamping seats to clamp the mandrel vertically through the crossbar and hinge rod. The position of the clamping plate can also be adjusted by rotating the knob and drive screw to accommodate mandrels of different lengths, thus realizing the horizontal and vertical clamping and fixing of the mandrel and the clamping of mandrels of different lengths.

[0007] A further feature of this invention is that a limiting hole is provided on one side of the drive plate, a limiting rod is slidably installed in the limiting hole, and the limiting rod is fixedly connected to the clamping plate.

[0008] By adopting the above technical solution, the cooperation between the limiting rod and the limiting hole can effectively limit the movement direction of the clamping plate and prevent the clamping plate from shifting or shaking during movement, thereby improving the positioning accuracy and stability of the mandrel when clamped in the horizontal direction.

[0009] A further feature of this invention is that a threaded hole is provided on one side of the drive plate, a drive screw is threadedly installed in the threaded hole, one end of the drive screw is rotatably mounted on the clamping plate, and a knob is fixedly installed on the other end of the drive screw.

[0010] By adopting the above technical solution, the operator only needs to turn the knob to drive the clamping plate to move precisely through the threaded transmission of the drive screw, so as to achieve fast and accurate clamping of mandrels of different lengths. The operation is simple and convenient, which greatly improves the versatility and flexibility of the device.

[0011] A further feature of this invention is that a vertical plate is fixedly installed on the top of the workbench, a hydraulic cylinder is fixedly installed on one side of the vertical plate, and the output shaft of the hydraulic cylinder is fixedly installed on the drive plate.

[0012] By adopting the above technical solution, the hydraulic cylinder provides a stable and powerful driving force, which can quickly and reliably drive the drive plate to move, thereby realizing the clamping operation of the mandrel. Compared with the traditional manual clamping method, the clamping efficiency and clamping force stability are significantly improved.

[0013] A further feature of this invention is that two T-shaped guide rails are fixedly installed on the top of the workbench, and a T-shaped hole with an open bottom is provided on one side of the drive plate, and the T-shaped guide rails are slidably connected to the T-shaped hole.

[0014] By adopting the above technical solution, the sliding fit between the T-shaped guide rail and the T-shaped hole provides stable guidance and support for the movement of the drive plate, effectively reducing the frictional resistance of the drive plate during the movement process, ensuring that the drive plate can slide smoothly and steadily, and guaranteeing the reliability of the clamping device operation.

[0015] A further feature of this invention is that two crossbars are fixedly installed on one side of the drive plate, and the crossbars pass through the lower clamping seat and the positioning plate. A hinge rod is hinged to the top of the crossbar, and the top end of the hinge rod is hinged to the corresponding drive seat.

[0016] By adopting the above technical solution, the horizontal movement of the drive plate can be converted into the vertical movement of the drive seat through the transmission structure of the crossbar and the hinge rod when the drive plate moves, realizing the linkage of horizontal clamping and vertical clamping operations, simplifying the operation process and improving the overall clamping efficiency.

[0017] A further feature of this invention is that a rotating groove is provided on one side of the clamping plate, an annular groove is provided on the inner wall of the rotating groove, an annular seat is fixedly installed on the driving screw, and the annular seat is rotatably connected to the corresponding annular groove.

[0018] By adopting the above technical solution, the rotating connection design between the annular seat and the annular groove allows the drive screw to rotate freely when moving the clamping plate, avoiding the impact on the movement accuracy of the clamping plate due to the obstruction of the screw rotation, and ensuring the smoothness and stability of the clamping plate adjustment process.

[0019] A further feature of this invention is that a rectangular hole is provided on the top of the drive seat, and a T-shaped guide rod is slidably connected to the rectangular hole; a controller is installed on the workbench, and a hydraulic cylinder is connected to the controller.

[0020] By adopting the above technical solution, the cooperation between the T-shaped guide rod and the rectangular hole ensures that the drive seat can slide stably along a fixed direction, guaranteeing the lifting accuracy of the upper clamping seat; while the connection between the controller and the hydraulic cylinder realizes the automated control of the hydraulic cylinder's operation, making it easy for operators to accurately adjust the clamping force and clamping stroke according to actual processing needs, thus improving the intelligence level and ease of operation of the device.

[0021] The beneficial effects of this utility model are:

[0022] (1) Place the mandrels into the placement slots on the lower clamping seat in sequence, so that the left end of the mandrels contacts the positioning plate, which can achieve the purpose of initial positioning of the mandrels.

The clamping plate can squeeze the mandrels. Through the cooperation of the positioning plate and the clamping plate, the purpose of clamping and fixing the mandrels in the horizontal direction can be achieved.

[0023] (2) When the drive plate moves, the drive plate can move the crossbar. The movement of the crossbar can move the drive seat downward through the hinge rod. The downward movement of the two drive seats can move the upper clamping seat downward. With the cooperation of the upper clamping seat and the lower clamping seat, the purpose of clamping and fixing the spindle in the vertical direction can be achieved.

[0024] (3) By rotating the knob and the drive screw, the drive screw can rotate and move at the same time under the action of the threaded hole. The drive screw can move the clamping plate and adjust the distance between the clamping plate and the drive plate, thereby achieving the purpose of clamping mandrels of different lengths.
