Embodiment Construction
[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0025] A method for processing an active joint is processed through the following steps:
[0026] 1) Prepare the material, cold draw the round steel, and process the diameter of the round steel to a tolerance of
[0027] 2) chamfering and cutting, the processed round steel is installed on a lathe, and the end face of the round steel is flattened with a lathe and chamfered, and then cut off according to the designed length with a lathe;
[0028] 3) Positioning. On the machining center of the vertical lathe, install a fixture for processing movable joints. The fixture includes a base and a column set in the center of the base. The top of the column is provided with external threads, and the pressure plate with the m...

The invention relates to a machining method of an activity joint. The machining method comprises the steps of material preparation, chamfering cutting, positioning, slope milling, groove milling, 70 degree slope milling and tapping drilling to machine the activity joint. The invention further provides a fixture for machining the activity joint. The fixture for machining the activity joint comprises a base and a vertical pillar arranged at the center of the base, wherein external screw thread is arranged at the top of the vertical pillar, and the vertical pillar is sleeved with a pressing platewith a middle hole; a nut is mounted on the vertical pillar; a cushion piece is mounted between the nut and the pressing plate; the base is provided with a middle block with an isosceles trapezoid section, and joint clamping grooves are formed in the two sides of the middle block, and bottom grooves are formed in the bottom of the joint clamping grooves; a set of opposite angles, positioned on the two sides of the middle block, of the base are subjected to excision, locating blocks are arranged at the two ends of the middle block of the base, and the half groove openings of the ends not beingsubjected to excision of the joint clamping grooves are covered with the locating blocks. According to the fixture, two round steel can be clamped at the same time, and the machining efficiency can be improved.
Description
technical field [0001] The invention relates to a method for processing an active joint and provides a fixture suitable for the method, which belongs to the technical field of mechanical processing. Background technique [0002] In the field of equipment processing, the processing of active joints is generally done by drilling holes in the center of round steel bars, and cutting corresponding inclined surfaces at the ends of bars according to needs. For example, to process a movable joint, the general processing procedure is to first use a φ28 round steel bar on the lathe to leave a margin of 0.5mm on the outer circle, chamfer 1.52x45°, and ensure a length of 82mm. Then grind the outer circle on the outer cylindrical grinder to Then, in the vertical machining center, clamp one end with a universal dividing head, and then adjust the angle so that the angle between the round steel center and the machine table is 20 degrees. Use an end mill to ensure that the inclined plane i...
