Description

Technical Field

[0001] The utility model relates to the field of cone bit blades, in particular to a processing tooling for cone bit blades. Background Technique

[0002] The cone bit is an important tool for oil drilling, and its working performance will directly affect the drilling quality, drilling efficiency and drilling cost. Most of the designs of cone bits are based on practical experience and combined with the trial-and-error method, and repeated designs and calculations are carried out. Therefore, the design accuracy is low, the cycle is long, it is difficult to improve the design quality, and only one bit can be designed each time the calculation is made, with low efficiency.

[0003] Under the action of the drilling pressure and the rotation of the drill string, the teeth of the cone bit crush and bite into the rock, and at the same time, a certain amount of sliding occurs to shear the rock. When the cone rolls at the bottom of the well, the teeth on the cone impact and press into the formation in turn. This action can crush a part of the rock at the bottom of the well, and at the same time, cut off the remaining part of the rock between the teeth by the shearing action brought by the sliding of the cone, so that the rock at the bottom of the well is completely broken and the wellbore can be extended.

[0004] In the manufacturing process of the cone bit, it needs to be clamped and processed. Due to its unique appearance shape, the tooling for clamping it needs to have a good clamping function. Therefore, a processing tooling for cone bit blades is proposed. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: including a support base plate 1 and a processing placement table 7. The middle part of the upper end surface of the support base plate 1 is provided with a processing placement table 7. Among them, the support base plate 1 is used to install the front and rear clamping components and provide a support function for the whole as the bottom base of the whole tooling. The processing placement table 7 is used to place the three-cone bit insert body and install the clamping components that provide left and right clamping for the three-cone bit insert body.

[0026] In this embodiment, please refer to Figure 1 and Figure 3 , the left end of the front side of the upper end surface of the support base plate 1 is provided with a first electric telescopic rod 2, and the right end of the front side of the upper end surface of the support base plate 1 is provided with a second electric telescopic rod 3. The output ends of the first electric telescopic rod 2 and the second electric telescopic rod 3 are fixedly connected with a fixed shaft 4. The outer side of the fixed shaft 4 is provided with a fixed plate 5, and a fixed bolt 6 is installed inside the fixed shaft 4. Among them, the first electric telescopic rod 2 and the second electric telescopic rod 3 are used to provide a lifting function for the fixed shaft 4 installed above. At the same time, the first electric telescopic rod 2 and the second electric telescopic rod 3 are symmetrically arranged front and rear based on the vertical central axis of the support base plate 1. The fixed shaft 4 provides a fastening function for the externally nested fixed plate 5 through the threaded connection with the fixed bolt 6. The fixed plate 5 is used to provide a clamping and fastening function for the front and rear ends of the three-cone bit insert body.

[0027] Further, please refer to Figure 1 , Figure 2 and Figure 4 , a dual-drive motor 8 is installed inside the processing placement table 7, and first connecting rods 9 are arranged at the output ends on the left and right sides of the dual-drive motor 8. Second connecting rods 10 are fixedly installed at the rear sides of the left and right end faces of the processing placement table 7, and a connecting plate 11 is arranged outside the second connecting rods 10. An engaging block 12 is fixedly installed on the upper side of the end face of the connecting plate 11 close to the vertical central axis of the processing placement table 7. Among them, the dual-drive motor 8 is used to provide a rotating function for the first connecting rods 9 at both output ends. The first connecting rods 9 enable the connecting plate 11 to move left and right through threaded connection with the connecting plate 11. The second connecting rods 10 provide a limiting function for the connecting plate 11 through sliding connection with the connecting plate 11. The engaging block 12 can stably clamp the irregular shapes on both sides of the roller cone bit cutter body through its "V"-shaped structural clamp.

[0028] Working principle: First, place the support base plate 1 at a designated position, then place the roller cone bit cutter body to be fixed on the upper surface of the processing placement table 7. Then turn on the dual-drive motor 8 to drive the first connecting rods 9 to rotate. Since the threads on the surfaces of the first connecting rods 9 on both sides of the dual-drive motor 8 are of opposite specifications, the connecting plates 11 on both sides of the processing placement table 7 can move synchronously inwards or outwards. After the dual-drive motor 8 is turned on, the engaging blocks 12 inside the connecting plates 11 stably clamp both sides of the roller cone bit cutter body. Then turn on the first electric telescopic rod 2 and the second electric telescopic rod 3, and they drive the fixing plate 5 fixed to the outside of the fixed shaft 4 by the fixing bolts 6 to press down on the front and rear ends of the roller cone bit cutter body through lowering, so that the roller cone bit cutter body can be processed. Since the fixing plates 5 on the front and rear sides can be independently adjusted in height according to the first electric telescopic rod 2 and the second electric telescopic rod 3 in an independent group, the roller cone bit cutter body can be better clamped and stabilized.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
