Embodiment 1

[0019] Embodiment 1, the structure of a V-shaped groove frame of the present invention is as follows: it mainly includes a tool holder, a steel ball, a compression spring, an adjustment screw, a positioning screw, a tool storage support plate, a positioning flat key and a positioning flat key locking screw , it is characterized in that the tool rest is provided with a semicircular counterbore for placing the knife handle (8), the semicircular counterbore below has a keyway, and the left and right sides of the tool rest are provided with through holes and threaded holes. The contact surface between the semicircular counterbore and the front end surface (a) of the handle (8) is a support surface. The semicircular counterbore is positioned in cooperation with the outer circle of the knife handle (b), and the unilateral gap between the knife handle (8) and the storage tool holder is 0.10-0.5 mm. The head of the handle (8) is provided with a screw hole, and a hexagon socket head sc...

Embodiment 2

[0020] Embodiment 2, the present invention relates to a V-shaped groove frame used by a vertical machining center and a vertical numerical control milling machine. Adopt knife handle (8) front end face (as figure 2 shown in middle a); the tool holder outer circle (b) coordinates the positioning (such as figure 2 shown in middle b); use hexagon socket head cap screws with a 60° head (such as image 3 3) to locate the axial direction of the tool holder to prevent the tool holder (8) from falling when placing the tool holder (8); use a flat key (such as image 3 shown in 6) and the keyway of the handle to position the circumferential direction of the handle to ensure the correct position of the keyway of the handle and the positioning key of the spindle when grabbing the knife; use steel ball + spring + screw (such as image 3 shown in 1, 2, and 3) to press the tool holder to locate the V-groove (c) (such as figure 2 The position shown in c) in the middle ensures that the hand...

Abstract

The invention discloses a V-shaped groove frame. A half-round counter bore which is used for placing a knife handle is formed in the V-shaped groove frame, a key groove is formed below the half-round counter bore, and through-holes and threaded holes are formed in left and right sides of the V-shaped groove frame. A front end face a of the knife handle is used for supporting; an external circle b of the knife handle is used for positioning in a matching mode; a socket head cap screw with a 60-degree head is used for positioning the axial direction of the knife handle to prevent the knife handle from falling when the knife handle is placed; a flat key is matched with the knife handle key groove to position the circumferential direction of the knife handle so as to guarantee the correctness of positions of the knife handle key groove and a main shaft positioning key during knife holding; and steel balls, springs and screws are used for tightly pressing the position of a knife handle positioning V-shaped groove c so as to guarantee that the knife handle is not separated from a knife rest when placed on the V-shaped groove frame and moved with a workbench. Compared with existing vertical machining center in-magazine knife holding technologies, the V-shaped groove frame has the advantages of being capable of automatically changing heavy, long and large knives which can not be placed into a magazine, broadening the application range of a vertical machining center and improving the universality of the vertical machining center.

Description

technical field [0001] The present invention relates to a kind of tool holder stored outside the warehouse of a vertical machining center and a vertical numerical control milling machine. It is installed on the workbench to realize placing heavy, long and large knives. Background technique [0002] Vertical machining is commonly used in the machinery industry, and the equipped tool magazine has corresponding restrictions on the weight, length, and diameter of the tool. For example: the φ315 milling cutter disc used for fine milling the top surface of the engine cylinder block cannot be put into the tool magazine, and the automatic replacement of the milling cutter disc can only be realized in the form of storing tools outside the warehouse. At present, the following two methods are usually used for the tools that cannot be put into the tool magazine: (1) manually changing the tool; (2) fixing the processing content without changing the tool. The disadvantage of the first m...
