Abstract
Description
Technical Field
[0001] This utility model relates to the field of circular saw clamping technology, specifically a positioning clamp. Background Technology
[0002] A circular saw is a common cutting tool. Its cutting blade is circular, and a drive motor drives the central blade to rotate at high speed to cut the material. During cutting, it is necessary to ensure the stability of the workpiece to ensure a good cutting effect and avoid inaccurate cutting due to shaking, which can also damage the cutting blade. Most positioning clamps use a hydraulically driven clamping structure to clamp the material with a pressure plate. However, the clamping of pipes is not stable enough. At the same time, since the thickness of the circular saw required for cutting different materials varies, the spacing requirements between the side guard plates protecting the circular saw also vary. Utility Model Content

The technical solution adopted includes a platform, a circular saw, a circular saw drive motor, and a hydraulic push rod. All of the above components are conventional equipment, and the circuit connection and power supply methods of each electrical device are also conventional technologies, which will not be described in detail later. The remaining parts include a circular saw moving structure, a feeding platform, a central notch, a clamping motor, a clamping screw, a clamping guide shaft, a right-side mounting frame, a bottom mounting protrusion, an auxiliary top block, a triangular groove, a right-side bidirectional screw, a right-side motor, and an L-shaped protective plate. The circular saw moving structure is set on the platform, and the circular saw is installed through the circular saw moving structure. The circular saw is driven by the circular saw drive motor. After the workpiece to be cut is clamped, the circular saw moving structure drives the circular saw to move, and at the same time, the circular saw drive motor drives the circular saw to rotate at high speed. The circular saw moves to the workpiece to be cut and cuts it. The feeding platform is fixed on the right side of the platform. The feeding platform has a central notch in the middle. The clamping motor is installed on the left side inside the central notch. The output shaft of the clamping motor extends to the right side and is located at the end of the output shaft. The right side of the loading platform has a fixed clamping screw, and a clamping guide shaft is fixed at the front and rear ends. Three bottom protrusions are integrally formed on the bottom of the right mounting frame; two of these protrusions are movable and fitted with the clamping guide shaft, while the other protrusion is fitted with the clamping screw. A hydraulic push rod is installed on the inner wall of the right mounting frame, with its output end extending to the left side of the frame and fixed to an auxiliary top block. A triangular groove is cut into the side of the auxiliary top block to ensure stable clamping of the pipe fitting during clamping. A right motor is installed on the front side of the right mounting frame, with its output shaft extending into the frame and a right-side bidirectional screw fixed at its output end. The rear end of the bidirectional screw is rotatably mounted on the rear side wall of the right mounting frame. L-shaped protective plates are symmetrically installed on the bidirectional screw, with the left and right portions positioned at the opening in the middle of the frame and in contact with the bottom surface of the opening. The start of the right motor rotates the bidirectional screw, adjusting the spacing between the two L-shaped protective plates to protect circular saws of different thicknesses.
[0004] As a preferred technical solution of this utility model, the circular saw moving structure includes a left mounting slot, a left lead screw, a moving drive motor, a left guide shaft, and a movable seat. Two left mounting slots are opened on the platform. The left guide shaft is fixedly installed in the rear mounting slot. The moving drive motor is installed on the left side of the platform. The output of the moving drive motor extends to the front left mounting slot and is fixedly connected to the left lead screw at its output end. The other end of the left lead screw is rotatably installed on the inner wall of the left mounting slot. The lower end of the movable seat is fitted into the left mounting slot. The two movable seats are respectively fitted with the left lead screw and movably fitted with the left guide shaft. The circular saw drive motor is installed on the front side of the front movable seat. The circular saw drive motor drives the rotating shaft that is rotatably installed between the two movable seats. The circular saw is detachably installed on the rotating shaft.
[0005] As a preferred technical solution of this utility model, an arc-shaped protective cover is fixed on the upper surface of the movable seat by a frame.
[0006] As a preferred technical solution of this utility model, a groove is opened on the feeding platform, and several rollers are evenly distributed in the groove, and through grooves are evenly distributed on the bottom surface of the groove.
[0007] As a preferred technical solution of this utility model, a limit plate is fixed at the outer end of the clamping guide shaft.
[0008] The beneficial effects of this utility model are as follows: by using a clamping motor and a clamping screw to move the right mounting frame to the left, the auxiliary top block moves to the left and cooperates with the convex plate on the left side of the feeding platform to clamp the material. The triangular groove can ensure the stable clamping of the pipe fitting. After clamping, the hydraulic push rod can further clamp it. According to the difference in the actual thickness of the circular saw, the distance between the two L-shaped protective plates can be adjusted by the right motor and the bidirectional screw to meet the protection of circular saws of different thicknesses.

After the clamping motor starts, it drives the clamping screw to rotate, causing the right mounting frame to move to the left, which in turn moves the auxiliary top block to the left. This, together with the convex plate on the left side of the feeding platform, clamps the material. The triangular groove ensures the stable clamping of the pipe fitting. The start of the hydraulic push rod can further clamp the material. After the material is clamped and positioned, the circular saw moving structure drives the circular saw to move towards the central notch, while the circular saw drive motor drives the circular saw to rotate at high speed. The circular saw moves towards the workpiece to be cut and cuts it.
