Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to an object clamping adjustable numerically controlled lathe. Background Technique

[0002] A numerically controlled machine tool is short for a numerically controlled lathe, which is an automated machine tool equipped with a program control system. The control system can logically process a program with control codes or other symbolic instructions, decode it, represent it in coded numbers, and input it into the numerical control device through an information carrier. Although the numerically controlled lathe realizes the clamping and fixing effect of an object, since only the clamping plate presses on both sides of the object, and the remaining positions of the object cannot be fixed, a stronger clamping force is required, thereby increasing the usage demand for the clamping mechanism, improving the strength of the clamping mechanism, and increasing the production cost. Content of the Utility Model

[0003] The purpose of the utility model is to provide an object clamping adjustable numerically controlled lathe to overcome the above-mentioned defects in the prior art.

[0004] According to an object clamping adjustable numerically controlled lathe of the utility model, it includes a bed body. A fixed frame and a slidable sliding frame are fixedly arranged on the bed body. Two symmetrically arranged sliding grooves are formed on the upper end surface of the bed body. An electric control mechanism is arranged in the sliding groove and is connected with the sliding frame. Two symmetrically arranged clamping plates are fixedly arranged on both the fixed frame and the sliding frame. Side clamping plates are connected to the front and rear ends of each clamping plate. A telescopic sliding plate is connected to the upper ends of the fixed frame and the sliding frame. A power motor is fixedly arranged on the upper end of the sliding plate. Spline cylinders are power-connected to the left and right ends of the power motor. A transmission rod is in spline fit with the two spline cylinders. Thread grooves are arranged at the mutually remote ends of the two transmission rods. Left and right clamps are threadedly connected to the mutually remote ends of the two transmission rods. Limiting plates are fixedly arranged at the mutually remote ends of the two clamping plates. The transmission rod is rotationally matched with the limiting plate. The left and right clamps are slidably matched with the clamping plate. The cross section of the left and right clamps is L-shaped. Arc blocks are fixedly arranged at the ends of each clamping plate close to the side clamping plate. Arc-shaped sleeves are fixedly arranged at the ends of each side clamping plate close to the clamping plate. The arc blocks are inserted into the arc-shaped sleeves for sliding connection. Rotary disks are connected to the arc-shaped sleeves. Spline rods are fixedly arranged in the rotary disks. Spline grooves for sliding connection with the arc-shaped sleeves and rotary rods for rotational connection with the arc-shaped sleeves are arranged at the spline rods. A gear is fixedly arranged in the arc-shaped sleeve at the position of the spline rod. An arc-shaped rack is fixedly arranged in the arc-shaped sleeve. The gear is meshed with the arc-shaped rack. Threaded rods are arranged on both the fixed frame and the sliding frame. The threaded rods are threadedly connected to the upper part of the sliding frame and rotationally connected to the lower part of the sliding frame.

[0005] The beneficial effects of the present utility model are as follows:

[0006] By controlling the deflection of the side clamping plate on the clamping plate and changing the deflection angle of the side clamping plate at the clamping plate, the clamping effect of the limiting plate and the side clamping plate on objects of different sizes can be improved, the clamping range of the device on the objects can be increased, objects of different shapes can be clamped, the practicability can be improved. Through the sliding frame that moves left and right, the position is adjusted according to the overall length of the object. When the limiting plate and the side clamping plate clamp the object, by controlling the movement of the left and right clamps, the left and right clamps on both sides are abutted and clamped with the left and right ends of the object, clamping the object from the circumferential direction and the left and right directions of the object, improving the clamping and positioning effect on the object, preventing the object from sliding and affecting the work, reducing the requirements for the clamping mechanism, and reducing the production cost.

[0022] Rotate the threaded rods on the fixed frame 11 and the carriage 12. The threaded rods are rotated manually or controlled to rotate by an external power source.

By rotating the rotating disk 23, drive the gear 27 to rotate through the spline rod 24. Under the meshing of the gear 27 and the arc-shaped rack 26, by the forward and reverse rotation of the rotating disk 23, make the arc-shaped sleeve 22 slide up and down at the arc block 21, thereby pulling the side clamping plate 25 hinged on the clamping plate 16 to swing, changing the angle between the side clamping plate 25 and the clamping plate 16.
