Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping technology, and in particular to a clamping fixture for chamfering. Background Technology

[0002] Before installing the chamfering tool, clean the tool holder thoroughly to ensure there are no impurities on the contact surfaces between the tool holder and the clamping device. Then, insert the chamfering tool into the clamping device and tighten the clamping nut firmly to ensure the tool is securely fixed.

[0003] In existing technologies, most workpieces are clamped using horizontal compressive force. However, horizontal clamping force is not suitable for clamping irregular workpieces, resulting in poor applicability. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. In the prior art, when clamping workpieces, most clamping is done by horizontal extrusion force. Horizontal clamping force is not easy to clamp irregular workpieces, so the application effect is poor. Therefore, a chamfering clamping fixture is proposed.

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

[0006] A chamfering clamping fixture includes a mounting plate and a lead screw, wherein the mounting plate has a groove and the two ends of the lead screw are rotatably connected to the mounting plate;

[0007] A clamping plate is slidably connected within the groove. A pressing component is installed on the clamping plate. The pressing component includes a square cavity, a piston plate, a spring, a horizontal plate, and a pressure plate. One end of the pressure plate is hinged to the clamping plate. The horizontal plate is fixedly connected to the pressure plate. The square cavity is fixedly connected to the clamping plate. One end of the piston plate is slidably connected within the square cavity. The spring is fixedly connected between the horizontal plate and the piston plate. A connecting pipe is fixedly connected to the square cavity.

[0008] Preferably, the pressing component further includes a limiting plate, which is fixedly connected to the end of the pressure plate away from the clamping plate.

[0009] Preferably, both clamps are threadedly connected to the lead screw.

[0010] Preferably, the mounting plate has two limiting grooves, which are located on both sides of the groove, and two support plates are slidably connected between the two limiting grooves.

[0011] Preferably, a sealing cavity is fixedly connected to each of the two limiting grooves, and a push plate is slidably connected to each end of the sealing cavity. The two push plates are fixedly connected to the support plate.

[0012] Preferably, a gas supply pipe is fixedly connected to the sealed cavity, and the gas supply pipe is connected to the connecting pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the lead screw rotates, the two clamping plates move in the center. During the movement of the clamping plates in the center, they will push the support plate to move. When the two clamping plates move in the center, they can complete the horizontal clamping of the workpiece.

[0015] As the gas inside the square cavity increases, it pushes the piston plate upward, and through the spring, it pushes the horizontal plate to move upward. At this time, the horizontal plate drives the pressure plate, so that the pressure plate rotates around the hinge point with the clamping plate. The limiting plate can move in a circle with the movement of the pressure plate and presses on the workpiece, exerting a pressure force on the workpiece from above, thus achieving a multi-directional processing effect on the workpiece.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-4 A chamfering clamping fixture includes a mounting plate 1 and a lead screw 2. The mounting plate 1 has a groove, and the two ends of the lead screw 2 are rotatably connected to the mounting plate 1. The lead screw 2 passes through the groove, and the outer surface of the contact point between the lead screw 2 and the mounting plate 1 is smooth.

[0024] A clamping plate 4 is slidably connected within the groove. Both clamping plates 4 are threadedly connected to the lead screw 2. A pressing component is installed on the clamping plate 4. The pressing component includes a square cavity 3, a piston plate 11, a spring 10, a horizontal plate 8, and a pressure plate 5. One end of the pressure plate 5 is hinged to the clamping plate 4. The horizontal plate 8 is fixedly connected to the pressure plate 5. The square cavity 3 is fixedly connected to the clamping plate 4. One end of the piston plate 11 is slidably connected within the square cavity 3. The spring 10 is fixedly connected between the horizontal plate 8 and the piston plate 11. The spring 10 pushes the horizontal plate 8 to prevent the pressure plate 5 from clamping the workpiece rigidly, effectively protecting the fragile workpiece. A connecting pipe 12 is fixedly connected to the square cavity 3. The pressing component also includes a limiting plate 9, which is fixedly connected to the end of the pressure plate 5 away from the clamping plate 4.

[0025] The mounting plate 1 has two limiting grooves, which are located on both sides of the groove. Two support plates 6 are slidably connected between the two limiting grooves. The screw rod 2 is located under the two support plates 6. Sealing cavities 7 are fixedly connected in the two limiting grooves. Push plates 13 are slidably connected to both ends of the sealing cavity 7. The two push plates 13 are fixedly connected to the support plates 6. An air supply pipe 14 is fixedly connected to the sealing cavity 7. The air supply pipe 14 is connected to the connecting pipe 12.

[0026] In this invention, the workpiece is first placed on the upper surface of two support plates 6. Then, the lead screw 2 is rotated. When the lead screw 2 rotates, the two clamping plates 4 move in the center. During the movement of the clamping plates 4 in the center, the support plates 6 are pushed to move. When the two clamping plates 4 move in the center, they can clamp the workpiece in the horizontal direction. When the support plates 6 move in the center, they squeeze the push plate 13 to slide in the sealing cavity 7 and compress the gas in the sealing cavity 7. The gas in the sealing cavity 7 enters the square cavity 3 through the connecting pipe 12 and the gas supply pipe 14. The gas in the square cavity 3 increases continuously, which can push the piston plate 11 to move upward. The spring 10 pushes the horizontal plate 8 to move upward. At this time, the horizontal plate 8 drives the pressure plate 5, so that the pressure plate 5 rotates with the hinge point with the clamping plate 4 as the fulcrum. The limiting plate 9 can move in a circle with the movement of the pressure plate 5 and squeeze on the workpiece, which has a squeezing force from above on the workpiece, so as to achieve a multi-directional processing effect on the workpiece.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0028] 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.
