Description

可迫緊穩固結合的切削刀具Cutting tool that can be tightly and firmly combined

本發明關於一種切削刀具，特別關於一種可以迫緊穩固結合的切削刀具。The present invention relates to a cutting tool, in particular to a cutting tool that can be tightly and firmly combined.

習用的切削刀具主要包含有一刀桿、一刀頭，與一鎖固件，該刀頭套接於該刀桿的前端，並以該鎖固件穿設於該刀頭而鎖固連接於該刀桿；為了避免該刀桿與該刀頭相對轉動，該刀桿的徑向相對側分別裝設有一限位塊，各定位塊皆凸出於該刀桿的端面，並嵌卡於凹設於該刀頭徑向相對側的定位槽。The conventional cutting tool mainly includes a tool bar, a tool head, and a locking member. The tool head is sleeved on the front end of the tool bar, and the locking member is inserted through the tool head to be locked and connected to the tool bar; To avoid relative rotation of the cutter bar and the cutter head, the radially opposite sides of the cutter bar are respectively provided with a limit block, and each positioning block protrudes from the end surface of the cutter bar and is inserted into the recess in the cutter head The positioning groove on the opposite side of the radial direction.

然而，為了讓定位塊可以順利的***刀頭的定位槽內，該定位槽的寬度會略大於該定位塊的寬度，例如，該定位塊的寬度為15.9公厘時，該第二定位槽的寬度為16.4公厘，而造成該定位塊與該定位槽之間形成一組裝間隙，當切削刀具高速旋轉時，該組裝間隙會影響刀頭旋轉時的穩定性，進而影響加工精度，而有待改善。However, in order to allow the positioning block to be smoothly inserted into the positioning groove of the cutter head, the width of the positioning groove will be slightly larger than the width of the positioning block. For example, when the width of the positioning block is 15.9 mm, the width of the second positioning groove The width is 16.4 mm, and an assembly gap is formed between the positioning block and the positioning groove. When the cutting tool rotates at a high speed, the assembly gap will affect the stability of the cutter head during rotation, and thus affect the machining accuracy, which needs to be improved .

有鑑於此，本發明的主要目的在於提供一種切削刀具，該切削刀具的限位迫緊件可以消除刀桿與刀頭之間的組裝間隙，以提升加工的穩定性。In view of this, the main purpose of the present invention is to provide a cutting tool whose position-limiting urging member can eliminate the assembly gap between the tool holder and the tool head, so as to improve the processing stability.

為了達到上述的目的，本發明提出一種可迫緊穩固結合的切削刀具，其包含： 一刀桿，其包含一端面與一第一定位槽，該第一定位槽凹設於該刀桿並於該端面形成開口； 一刀頭，其一端與該刀桿的端面鄰接，並以一鎖固件連接於該刀桿，該刀頭鄰近該刀桿的一端凹設有一第二定位槽；以及 一限位迫緊件，係設於該刀桿的第一定位槽與該刀頭的第二定位槽之間，其包含 一定位塊，係設於該刀桿的第一定位槽與該刀頭的第二定位槽，該定位塊包含兩迫緊槽與一調整孔，該兩迫緊槽分別於該定位塊的相對側形成一側開口，該調整孔自該定位塊的外側面向內凹設，位於該兩迫緊槽之間，並與該兩迫緊槽連通； 兩迫緊件，係分別設於該定位塊的兩迫緊槽內；以及 一調整件，係插設於該定位塊的調整孔而與該定位塊螺合連接，該調整件的外周形成有外徑漸縮的錐狀推抵面，該推抵面可選擇性地抵於該兩迫緊件。 In order to achieve the above objectives, the present invention provides a cutting tool that can be tightly and firmly combined, which includes: A knife bar including an end surface and a first positioning groove, the first positioning slot being recessed in the knife bar and forming an opening on the end surface; A cutter head, one end of which is adjacent to the end face of the cutter bar and connected to the cutter bar by a locking member, and one end of the cutter head adjacent to the cutter bar is recessed with a second positioning groove; and A position-limiting pressing member is arranged between the first positioning groove of the cutter bar and the second positioning groove of the cutter head, and includes A positioning block is arranged in the first positioning groove of the cutter bar and the second positioning groove of the cutter head. The positioning block includes two pressing grooves and an adjustment hole. The two pressing grooves are respectively opposite to the positioning block.
