Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a drilling machine positioning fixture for processing a wear-resistant disc of a mud pump. Background Art

[0002] The mud pump is a key equipment in oil drilling operations. It mainly provides the necessary energy for the circulation of drilling fluid during drilling operations, and delivers drilling fluid into the drilling tool at a certain pressure and flow rate, which plays a role in stabilizing the well wall, cooling the drill bit, and cleaning the wellbore. At the hydraulic end of the mud pump, the wear plate is a wear-resistant part of the hydraulic end. The structure of the wear plate is disc-shaped, refer to Figure 3 As shown, there are multiple holes evenly distributed on the circumference of the wear-resistant disk. The multiple holes on the wear-resistant disk are processed by a drilling machine. During processing, the workpiece is fixed on the processing platform of the drilling machine, and indexing processing is performed after alignment. The existing processing method has the following defects: the workpiece is fixed on the working platform of the drilling machine during processing, and each workpiece needs to be aligned before processing. The alignment work needs to be repeated, and the effect of aligning once and then only processing can not be achieved, thereby reducing the processing efficiency. Therefore, it is necessary to propose improvements. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a drilling machine positioning fixture for processing mud pump wear-resistant discs. The utility model aims to achieve rapid clamping and positioning of the wear-resistant discs on the drilling machine by improving the fixture structure on the drilling machine. Subsequent processing only needs to be carried out according to the division, and there is no need to align each part, which greatly improves work efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A drilling machine positioning fixture for processing mud pump wear-resistant discs includes a drilling machine working platform, on which a three-jaw chuck body is fixed, on which a clamping jaw is provided, and on one side of the upper surface of the three-jaw chuck body a positioning pin for positioning the wear-resistant disc is provided, and the positioning pin is used to adapt to the radial groove on the wear-resistant disc to achieve clamping and positioning of the wear-resistant disc.

[0006] As a further limitation of the above solution, there are two positioning pins, and the two positioning pins are arranged along a radial direction of the three-jaw chuck body.

[0007] To further limit the above scheme, a locating pin installation hole is processed on the three-jaw chuck body, the locating pin is inserted into the locating pin installation hole with interference fit, and the height of the locating pin extending above the upper surface of the three-jaw chuck body is less than the depth of the radial groove of the wear-resistant disk.

[0008] As a further limitation of the above solution, the three-jaw chuck body is clamped and fixed on the working platform of the drilling machine by a clamping structure.

[0009] To further define the above scheme, the clamping structure includes a clamping plate and a clamping bolt, a T-block is provided at the lower end of the clamping bolt, the clamping bolt is connected to the T-slot on the working platform of the drilling machine through the T-block, the clamping plate is passed through the clamping bolt, one end of the clamping plate is pressed on the three-jaw chuck body, the lower part of the other end of the clamping plate is supported by a support block, and a clamping nut is screwed on the clamping bolt to clamp the clamping plate.

[0010] As a further limitation of the above solution, the pressure plate is provided with a waist-shaped hole for the clamping bolt to pass through and adjust the position.

[0011] The advantages of this utility model compared with the prior art:

[0012] This solution combines a three-jaw chuck with a drilling machine work platform, and sets a locating pin on the three-jaw chuck, which is adapted to the radial groove on the wear-resistant disk. Through the centering effect of the three-jaw chuck and the positioning effect of the locating pin and the radial groove on the wear-resistant disk, the wear-resistant disk can be quickly clamped and positioned on the drilling machine, and subsequent processing only needs to be performed according to the indexing. Therefore, each wear-resistant disk is directly positioned by the radial groove on itself and the locating pin on the three-jaw chuck before processing, and then positioning can be achieved by clamping with three jaws. There is no need to align each part, which greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
