Description

Technical Field

[0001] The present application relates to the technical field of tool, in particular to a non-adjustable reamer. Background Art

[0002] A reamer is a rotary tool with one or more teeth used to remove a thin layer of metal from the surface of a machined hole. A reamer is a rotary finishing tool with a straight or spiral edge, used for expanding or repairing holes. Reamers usually require higher machining accuracy than drills due to their small cutting volume. They can be operated manually or installed on a drilling machine.

[0003] After checking the announcement number: CN208961134U, a reamer is disclosed. This technology discloses "including a shank and a cutter head arranged at one end of the shank, the cutter head is provided with a plurality of chip grooves, and the plurality of chip grooves are evenly distributed on a circle centered on the axis of the shank; the chip grooves penetrate the side wall and top surface of the cutter head, and the inner wall of the chip groove is provided with a receiving groove for accommodating a blade, the top of the blade extends out of the top surface of the cutter head to form a secondary cutting edge, and the side of the blade away from the axis of the shank extends out of the side wall of the cutter head to form a first main cutting edge; wherein, the blade is made of artificial synthetic diamond, and a protruding conical platform is provided on the back of the blade, and the conical platform is matched with a groove provided at the bottom of the receiving groove, etc. The reamer provided by the utility model has the technical effects of less wear during the reaming process and the blade can remain sharp for a long time, etc.";

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing reamer structure is too simple, and the reamer structure does not have a connecting component. The prior art generally adopts the method of directly welding the cutter head to the connecting pipe when installing the cutter head body. Since the cutter head will have a certain wear after a certain period of use, the cutter head needs to be replaced separately. The welding method makes the cutter head replacement more troublesome. There is no connecting component, which makes it inconvenient to quickly replace the cutter head in the reamer separately, reducing the practicality of the reamer; secondly, the existing reamer structure does not have a shock-absorbing component. Since the reamer structure will generate a certain vibration when the reamer is used to drill a hole in the workpiece, the long-term vibration when the reamer is working will cause certain damage to the reamer. There is no shock-absorbing component, which makes it inconvenient for the reamer to have a shock-absorbing effect, reducing the service life of the reamer. Utility Model Content

The top of the support seat 26 is fixedly connected to a motor 25, and the motor 25 plays a role in driving the connecting component 2, and the motor 25 The output end passes through one end of the connecting tube 4 and is fixedly connected with a connecting rod 24, so that the output end of the motor 25 can drive the connecting rod 24 to rotate. The inner wall of the connecting tube 4 is fixedly connected with a bracket 23. The end of the connecting rod 24 facing away from the output end of the motor 25 passes through the bracket 23 and is fixedly connected with a bidirectional screw rod 28, so that the rotation of the connecting rod 24 can drive the bidirectional screw rod 28 to rotate, and the end of the bidirectional screw rod 28 away from the connecting rod 24 is rotatably connected to the inner wall of one side of the bracket 23. Two sliders 203 are sleeved on the outer surface of the bidirectional screw rod 28, so that the rotation of the bidirectional screw rod 28 can drive the two sliders 203 to move. The bottom ends of the two sliders 203 are fixedly connected with a fixing plate 27 used in conjunction with the connecting pin 201, so that the movement of the slider 203 can drive the fixing plate 27 to move. The two fixing plates 27 move toward opposite sides to cancel the fixation of the connecting pin 201, thereby facilitating the rapid replacement of the cutter head body 6.
