specific Embodiment approach 1

[0024] Specific implementation mode one: combine Figure 1 to Figure 4 To illustrate this embodiment, a trapezoidal threaded hole chuck jaw processing method described in this embodiment includes the following steps:

[0025] Step 1: Rough milling: Mill the raw material into a cuboid with a size of 290mm×144.7mm×400.7mm on a horizontal milling machine. The raw material can process two workpieces, milling the size of the stepped surface A1 to a height of 103mm, and milling the size of the stepped surface B2 to a width of 103mm;

[0026] Step 2: Rough drilling: the fitter first draws the axis of threaded hole 3, and then drills to φ55;

[0027] Step 3: Rough boring: boring threaded hole 3 to φ88 on CNC milling machine;

[0028] Step 4: heat treatment: heat treat the material until the Rockwell hardness is 31-35HRC;

[0029] Step 5: Grinding the end face D4: Grind the two end faces D4 separately on a surface grinder until the distance between the two end faces D4 is L4, the va...

specific Embodiment approach 2

[0043] Specific implementation mode two: combination Figure 1 to Figure 4 To illustrate this embodiment, the process of heat treatment in Step 4 of this embodiment is as follows: first heat the material in a medium-temperature furnace with a temperature range of 820-840°C for 30 minutes, and then put it into a water tank to cool to a temperature of 300-400°C , and then put it into an oil tank to cool to normal temperature, and finally put it into a tempering furnace with a temperature of 560°C and temper it for 2 hours. The undisclosed technical features in this embodiment are the same as those in the first embodiment.

specific Embodiment approach 3

[0044] Specific implementation mode three: combination Figure 1 to Figure 4 To describe this embodiment, after the end face D4 is ground in Step 5 of this embodiment, the two end faces D4 are demagnetized. The undisclosed technical features in this embodiment are the same as those in the first or second specific embodiment.

Abstract

The invention discloses a machining method for a trapezoidal threaded hole chuck claw and relates to machining methods. Through the machining method, the problem that through an existing machining process, the machining precision of a trapezoidal threaded hole chuck claw cannot be ensured is solved. The machining method comprises the following steps of rough milling, rough drilling, rough boring,heat treatment, grinding of an end face D, finish milling, finish hole turning, cutting, finish boring, planing of antiskid teeth, heat treatment of the antiskid teeth, chamfering of all edges and printing of a figure number. The machining method is used for machining of the trapezoidal threaded hole chuck claw.

Description

technical field [0001] The invention relates to a mechanical processing method, in particular to a processing method for a chuck claw of a trapezoidal threaded hole. Background technique [0002] The chuck claw is a kind of machine tool accessory used by CNC vertical lathe. It is clamped by half-hole trapezoidal thread. This part is a vulnerable part. After wear and tear, it needs to be replaced with a new chuck claw to ensure the safety of clamping. The existing processing methods have low processing accuracy, especially the processing of trapezoidal thread, and its accuracy is difficult to meet the requirements. Contents of the invention [0003] In order to solve the problem that the existing processing technology cannot guarantee the processing accuracy of the trapezoidal threaded hole chuck claw, the present invention further proposes a trapezoidal threaded hole chuck claw processing method. [0004] The technical scheme that the present invention takes for solving t...
