Specific embodiments
[0026] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0027] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0028] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present invention provides a fixture for producing a PCD adjustable precision reamer with convenient adjustment, including:
[0029] The frame body 1 is provided with a clamping mechanism. It should be noted that the PCD adjustable precision reamer 6 is clamped and fixed by the clamping mechanism;
[0030] The clamping mechanism includes a power motor 2, a connecting shaft 3, a connecting rod 4, a clamping sleeve 5, a driving member 7, a driven member 8, a clamping member 9, a top plate 11, a first steel ball 14 and a second steel ball 15. The power motor 2 is fixedly installed on the frame body 1, the output end of the power motor 2 is fixedly connected to the connecting shaft 3, the connecting rod 4 is fixedly connected to the connecting shaft 3 and the clamping sleeve 5, the driven member 8 is fixedly connected to the clamping member 9, the top of the driving member 7 is fixedly connected to the top plate 11, the first steel ball 14 is fixedly installed on the top plate 11, and the second steel ball 15 is fixedly installed on the frame body 1.
[0031] Through the above clamping mechanism, the PCD adjustable precision reamer 6 is inserted into the clamping sleeve 5. When the power motor 2 is started, the connecting shaft 3 can drive the connecting rod 4 to rotate, and the connecting rod 4 drives the clamping sleeve 5 to rotate. Furthermore, the top plate 11 can be driven by the steel ball 14 to rotate. The steel ball 15 presses the steel ball 14, so that the steel ball 14 can drive the top plate 11 to move, causing the inner plate 12 to press the spring 13. At the same time, the top plate 11 drives the active part 7 to move. Thus, the hydraulic oil 10 can be used to drive the driven part 8 to move, and the driven part 8 drives the clamping part 9 to move. The four clamping parts 9 clamp and fix the PCD adjustable precision reamer 6, eliminating the need for manual repeated rotation of the screw, reducing the working intensity, and making the adjustment more convenient.
[0032] Specifically, the same PCD adjustable precision reamer 6 is clamped by multiple clamping parts 9. It should be noted that the PCD adjustable precision reamer 6 is clamped and fixed.
[0033] Specifically, four holes are provided on the clamping sleeve 5, and the holes are filled with hydraulic oil 10. The active part 7 and the driven part 8 are slidably and sealedly installed in the holes. Sealing gaskets are embedded on both the active part 7 and the driven part 8, and the sealing gaskets are in sealing contact with the holes. It should be noted that when the active part 7 moves vertically, the driven part 8 can move horizontally.
[0034] Specifically, an inner plate 12 is fixedly arranged at the bottom end of the top plate 11. An inner groove is provided on the clamping sleeve 5, and the inner plate 12 is slidably installed in the inner groove. A spring 13 is fixedly arranged between the bottom of the inner plate 12 and the inner wall of the bottom of the inner groove. It should be noted that when the steel ball 14 is not stressed, the spring 13 will drive the inner plate 12 to move upward due to its own elastic force, and thus the top plate 11 can be driven to move upward.
[0035] Specifically, the steel ball 14 is in contact with the steel ball 15. It should be noted that the steel ball 15 can press the steel ball 14.
[0036] Specifically, two mounting holes are provided at the top of the frame 1. The top plate 11 is located above the clamping sleeve 5. It should be noted that the position of the top plate 11 is limited.
[0037] The above has introduced in detail a fixture for the production of a PCD adjustable precision reamer with convenient adjustment provided by the present utility model. Specific embodiments are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
