Description

Technical Field

[0001] This utility model relates to the field of reamer technology, and more specifically, to a high-torque PCD reamer for CNC machine tools. Background Technology

[0002] A reamer is a rotary cutting tool with one or more cutting teeth used to remove a thin layer of metal from the surface of a machined hole. Reamers are rotary finishing tools with straight or spiral cutting edges, used for enlarging or repairing holes. Because of the small cutting volume, the machining accuracy requirements of reamers are usually higher than those of drill bits. They can be operated manually or mounted on a drilling machine.

[0003] For example, patent CN218694546U discloses a high-torque PCD reamer for CNC machine tools, including a PCD reamer head and a reamer connecting end. The left end of the PCD reamer head is connected to a left mounting block, and the right end of the reamer connecting end is connected to a right mounting block. Both the upper and lower ends of the right mounting block are connected to the left mounting block on the right side by fastening bolts and nuts. A first groove is formed in the middle of one side of the right mounting block, and a second groove is formed in the middle of one side of the left mounting block. A first connecting block is set at the bottom of the first groove, and a second connecting block is set at the bottom of the second groove. The first connecting block and the second connecting block are connected by a telescopic rod, and an adjustment knob is set on the telescopic rod.

[0004] When the above-mentioned device is in use, by setting up a left mounting block, a right mounting block, a first connecting block, a second connecting block, a telescopic rod, fastening bolts and nuts, the distance between the PCD reamer head and the reamer connection end can be adjusted by utilizing the cooperation between them. However, when the PCD reamer head comes into contact with the workpiece, the pressure generated can easily cause the telescopic rod to slide, thereby affecting the stability of the PCD reamer head installation and operation. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high-torque PCD reamer for CNC machine tools. The technical problem to be solved by this utility model is: how to make the PCD reamer head more stable during installation and operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-torque PCD reamer for CNC machine tools, comprising a reamer mounting end, a connecting mounting sleeve provided on one outer end face of the reamer mounting end, a connecting mounting block provided at one end of the connecting mounting sleeve, a limiting baffle provided in the middle of the outer end face of the connecting mounting block, a first spring provided on one side of the outer end face of the connecting mounting block, and a connecting sliding sleeve provided on the outside of one end of the connecting mounting block;

[0007] A limiting partition plate is provided on one side of the outer end face of the connecting sleeve, a second spring is provided on the outer end face of the connecting sleeve, a connecting mounting plate is provided on the side of the outer end face of the connecting sleeve away from the limiting partition plate, and multiple threaded rods are provided on one side of the outer end face of the connecting mounting plate.

[0008] In a preferred embodiment, one end of the reamer mounting end is provided with a concave cutting groove, and the middle part of the one end of the reamer mounting end is provided with a square mounting groove.

[0009] In a preferred embodiment, locking bolts are provided on both sides of the outer end face of the connecting mounting sleeve, and a limiting mounting base is provided at one end of the connecting sliding sleeve on the outside of the connecting mounting plate.

[0010] In a preferred embodiment, a limiting square groove is formed inside the connecting sleeve, and an internal hexagonal locking screw is provided on one side of the outer end face of the limiting square groove.

[0011] In a preferred embodiment, a reamer body is provided on the outside of one end of the limiting mounting base, and a square insert is provided on one end of the reamer body.

[0012] In a preferred embodiment, the threaded rod passes through the end face of the connecting mounting sleeve and extends to the outside of the connecting mounting sleeve. A locking nut is provided on one side of the connecting mounting sleeve on the outer end face of the threaded rod, and a tightening nut is provided on the other side of the connecting mounting sleeve on the outer end face of the threaded rod.

[0013] In a preferred embodiment, the outer end face of the connecting mounting block is adapted to the inner end face of the mounting square groove and the limiting square groove, and the diameter of the outer end face of the limiting mounting base in the right-view direction is larger than the diameter of the outer end face of the connecting sliding sleeve in the right-view direction.

[0014] In a preferred embodiment, the inner end face of the limiting square groove is adapted to the outer end face of the square insert.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] In actual use, with the corresponding arrangement of the connecting mounting block, connecting sleeve, first spring, second spring, and limiting partition plate, the two ends of the second spring will press against the inner sides of the connecting mounting plate and the limiting partition plate, thereby causing the limiting mounting base to fit against one side end face of the connecting mounting plate. The two ends of the first spring will press against one side end face of the limiting baffle and the limiting partition plate. The connecting mounting block and the limiting mounting base can be used as the shaft connector for the reamer mounting end to drive the reamer body to rotate, thereby making the power transmission between the reamer mounting end and the reamer body more stable.

[0017] Simultaneously, with the threaded rod, locking nut, and top-tightening nut in their corresponding positions, the gap between the reamer body and the reamer mounting end can be adjusted by rotating the locking nut to change the distance between the connecting mounting sleeve and the connecting mounting plate. At the same time, rotating the top-tightening nut causes it to fit against the outer end face of the connecting mounting sleeve. Thus, with the locking nut and top-tightening nut in tandem, the adjusted position of the connecting mounting plate can be locked and fixed, ensuring the stability of the reamer body when processing the workpiece.
