Description

TECHNICAL FIELD

[0001] The utility model relates to numerical control machine tooling equipment part technical field especially relates to a kind of positioning block for connecting tool tower and tool holder. BACKGROUND

[0002] In existing numerical control machine tool, tool holder and tool tower are combined into shape, generally, tool holder will be provided with protruding positioning block, and tool tower slot is set on tool tower, positioning protruding block is placed into tool tower slot to be positioned, further fixed connection is needed subsequently using bolt structure.The positioning block and tool tower slot in the above structure are generally adopted clearance fit mode, and the two only play the role of preliminary position limitation, cannot realize the stable connection between the two, and the connection stability is not enough. SUMMARY

[0003] The utility model provides a kind of positioning block for connecting tool tower and tool holder to overcome the above problems, and the positioning connection stability between tool tower and tool holder is significantly enhanced, and it is convenient to disassemble and assemble, and flexible to use.

[0004] The technical scheme of the utility model is:

[0005] The positioning block for connecting tool tower and tool holder, the tool tower has tool tower slot for positioning cooperation with positioning block, the positioning block is equipped with bolt hole for the penetration bolt and is fixedly connected with tool holder by bolt;The positioning block further has two opposite positioning walls, the opening that can be elastically deformed is opened between the two positioning walls, the distance of the outer side of the two positioning walls under natural state is slightly greater than the width of tool tower slot, and the two positioning walls can be clamped into tool tower slot to form transition fit by the elastic deformation of opening.

[0006] By means of the above structure, the positioning block can be connected with tool holder through bolt hole, and is clamped and cooperated with tool tower slot through two positioning walls, so as to ensure the stable connection between tool tower and tool holder;The opening is elastically deformed and shrinks after being extruded by external force, the distance of the two positioning walls is reduced, so as to be smoothly entered into tool tower slot, and after elastic reset of opening, the two positioning walls are transitionally cooperated with tool tower slot, realize close connection, which is not easy to loosen and can be flexibly disassembled and replaced.

[0007] Further, in the positioning block for connecting tool tower and tool holder, the positioning wall and tool tower slot are zero-to-zero cooperation.

[0008] Further, in the positioning block for connecting tool tower and tool holder, the distance of the outer side of the two positioning walls under natural state is 0.02mm greater than the width of tool tower slot.

[0009] Further, the positioning block for connecting the cutter tower and the cutter base, one of the positioning walls is a straight wall, and the other positioning wall is L-shaped.

[0010] Further, the positioning block for connecting the cutter tower and the cutter base, one of the positioning walls is a straight wall, and the other positioning wall is L-shaped.

[0011] Further, the positioning block for connecting the cutter tower and the cutter base, one of the positioning walls is a straight wall, and the other positioning wall is L-shaped.

[0012] The positioning block for connecting the cutter tower and the cutter base has the advantages that:

[0013] The positioning block for connecting the cutter tower and the cutter base has the advantages that:

[0014] The positioning block for connecting the cutter tower and the cutter base has the advantages that: BRIEF DESCRIPTION OF DRAWINGS

[0015] Figure 1 The positioning block for connecting the cutter tower and the cutter base has the advantages that: DETAILED DESCRIPTION

[0016] The positioning block for connecting the cutter tower and the cutter base has the advantages that:

[0017] Referring to FIG. 1, the positioning block for connecting the cutter tower and the cutter base is shown. Figure 1 The positioning block for connecting the cutter tower and the cutter base has the advantages that:

[0018] The opening 3 between the two positioning walls 2 is elastically deformable, and the distance between the outer sides of the two positioning walls 2 in a natural state is slightly greater than the width of the tool turret slot.

[0019] In use, the two positioning walls 2 are first connected to the tool holder through the bolt holes 1, then the opening 3 between the two positioning walls 2 is squeezed to deform and shrink, and the two positioning walls 2 are inserted into the tool turret slot, the squeezing force on the opening 3 is released, the two positioning walls 2 are naturally reset, and the two positioning walls 2 are in zero-to-zero fit with the tool turret slot, closely attached, and stably connected.
