The quality of its working performance will directly affect the drilling quality, drilling efficiency and drilling cost. After the oil drill bit is processed by the machining center, it needs to be Surface treatment of the drill bit, including surface grinding and painting, but due to the large size of the drill bit, it is necessary for the staff to move around the drill bit for processing, which is inconvenient to operate and has low efficiency. It is easy to fall over during processing, which will not only cause damage to the drill bit but also cause injury to the staff.

Moreover, the existing oil drill bit surface treatment fixture adopts one-to-one type, and one fixture can only clamp the oil drill bit of one diameter, which has low economic benefit.

Utility model content

The utility model discloses a fixture for the surface treatment of an oil drill bit. The oil drill bit is clamped by a fixture used for the surface treatment of the oil drill bit. A fixed baffle plate cooperates with a movable baffle plate to support the thick upper half of the oil drill bit. The technical means that the fixture is installed on the base with the bearing solves the problems of potential safety hazards in the surface treatment of the oil drill bit, one fixture can only hold one type of oil drill bit, which leads to the fixture, and the work efficiency of surface treatment is low.

In order to solve the above-mentioned technical problems, the utility model specifically adopts the following technical solutions:

A fixture for surface treatment of an oil drill bit, comprising a base, a casing mounted on the top of the base, a fixed block fixed on the top surface of the casing, the middle of both sides of the fixed block being slotted and the A movable block that can slide along the groove is installed in the groove, the top surface of the movable block and the top surface of the fixed block are on the same horizontal plane, the side wall of the casing is provided with threaded holes and the threaded holes are connected with the horizontal holes. The threaded telescopic rod is threaded through the side wall of the casing. One end of the threaded telescopic rod inside the casing is connected to a locking block for fixing the oil drill bit, and one end of the threaded telescopic rod away from the casing is connected to the handle. .

Compared with the prior art, the utility model has the following beneficial effects:

The utility model provides a fixture for the surface treatment of an oil drill bit. The oil drill bit is clamped by the fixture and can be driven to rotate, thereby improving the work efficiency and work safety of the surface treatment. The movable baffle plate is used to support the upper half of the oil drill bit with the movable baffle plate and the fixed baffle plate, so that the clamp can hold oil drill bits of different diameters and improve the economy of the clamp.

Detailed ways

The specific content of the present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

As shown in Figure 1 and Figure 2:

A fixture for surface treatment of an oil drill bit, comprising a base 1, a housing 2 mounted on the top of the base 1, a fixed stopper 3 fixed on the top surface of the housing 2, and the fixed stopper 3 on both sides. There is a slot in the middle and a movable block 4 that can slide along the slot is installed in the slot. The top surface of the movable block 4 and the top surface of the fixed block 3 are in the same horizontal plane, and the side wall of the casing 2 is opened The threaded hole is threaded with a threaded telescopic rod 5 horizontally passing through the side wall of the casing 2. The threaded telescopic rod 5 is located inside the casing 2 and one end is connected to a locking block for fixing the oil drill bit. 7. One end of the threaded telescopic rod 5 away from the housing 2 is connected to the handle 6 .

As mentioned above, the usage mode of the present invention is to push the movable stopper 4 according to the diameter of the upper half of the oil drill bit which is surface-treated as required, so as to open the space between the fixed stopper 3 and the movable stopper 4. The hole position is the gear position, adjust to the gear position that can put the bottom of the oil drill bit into the position where the upper half can be stuck, place the oil drill bit to the top of the fixed block 3, turn the handle 6, The threaded telescopic rod 5 is screwed into the casing 2 , and finally the oil drill bit is locked by the locking block 7 to realize clamping.

As shown in FIG. 2 , a concave hole for placing the bearing 9 is provided in the center of the top of the base 1 , and the bottom of the housing 2 is in the shape of a cylinder fitted with the inner ring of the bearing 9 ; The bearing 9 is locked, the bottom of the housing 2 is cylindrically inserted into the inner ring of the bearing 9, and the recessed hole is stepped, and the bottom of the housing 2 extends from the bearing 9 into the inner ring. into the stepped hole.

As shown in FIG. 2 , the housing 2 is provided with a wear-resistant buffer layer 8 for buffering and fixing relative to the inner wall of the locking block 7 ; Secure and prevent damage to the connections on the lower part of the oil drill bit.

As shown in FIG. 3 , the arms on both sides of the fixed block 3 evenly open through holes, and the arms on both sides of the movable block 4 evenly open threaded through holes according to the spacing of the through holes opened by the fixed block 3; Yes, a plurality of through holes for fixing the movable stopper 4 are evenly arranged, and oil drills of different diameters are supported by the movable stopper 4 of different gears in cooperation with the fixed baffle.
