Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a cutting cylinder connecting plate for numerical control machine tools. Background Art

[0002] The tool-breaking cylinder is a force-enhancing gas-liquid conversion device, which is mainly used for spindle tool-breaking in the automatic or semi-automatic tool exchange mechanism of machining center machine tools and CNC milling machines. It can also be used as a clamping device for fixtures and other mechanisms. Its working principle is that compressed air acts on the piston of the tool-breaking cylinder to generate thrust, and the tool head is clamped by the pull cylinder. When cutting, the tool head is loosened and cleaned by "blowing", which is convenient for tool changing and realizes the action of the mechanical device;

[0003] During the operation of CNC machine tools, the cutting cylinder will be affected by the vibration of the machine tools. However, the installation of the existing CNC machine tool cutting cylinder connecting plate is generally fastened by bolts. The tightening of the bolts will be affected by vibration and easily loosen. Specifically, the vibration will cause a small "lateral" movement at the bolt connection, causing the two connected parts to move relative to each other, and the bolt head or nut and the connected part will also move. These repeated movements will offset the friction between the bolt and the connected part, and may eventually cause the bolt thread to "rotate loose", causing the joint to lose its clamping force and reduce the stability of the connection between the cutting cylinder and the mounting plate. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art, and the proposed cutting cylinder connecting plate for CNC machine tools utilizes the design of the mounting mechanism. Due to the inclined structure of the latch, when the fixing plate is inserted into the fixing groove, the latch can be squeezed and contracted, so that the fixing plate can be directly inserted into the fixing groove, and then reset and inserted into the slot under the action of the spring to complete the fixation, and no loosening due to vibration will occur.

[0007] The side wall of the mounting plate is evenly distributed with a plurality of positioning rods, and the side wall of the connecting plate is provided with a plurality of positioning holes matched with the positioning rods.

[0008] Preferably, the mounting mechanism comprises a limit plate slidably connected in the slide slot, a latch is fixedly mounted on the side wall of the limit plate, the latch extends from a side away from the limit plate to the inside of the slide slot, and the limit plate and the slide slot are elastically connected via two springs.

[0009] Preferably, a storage hole is provided on the side wall of the connecting plate, and the storage hole is connected to the two slide grooves via a through hole. A pulling block is provided inside the storage hole, and one end of the pulling block is fixedly connected to a pull rope, and the other end of the pull rope passes through the through hole and forks to be fixedly connected to the two limit plates respectively.

[0010] Preferably, the slide groove is a T-shaped structure, the length of the opening is smaller than the length of the inner cavity, and cooperates with the limiting plate to achieve the purpose of limitation.

[0011] Preferably, the lower end surface of one side where the bolt extends is an inclined structure, and two slots adapted to the bolt are symmetrically arranged on the inner side of the fixing groove.

[0012] Preferably, the pulling block is composed of a left rectangular block, a middle cylindrical body, and a right threaded column, and the threaded column is threadedly connected to the through hole.

[0013] The utility model has the following beneficial effects:

[0014] 1.
