[0002] In the prior art, the processing method of the rack uses milling cutters of different standards to directly grind the raw materials. For the rack with small modulus, this processing is relatively simple and convenient; but when the modulus of the rack increases , it is not suitable to use the milling cutter to directly grind into teeth, so people usually use a planer to plan the rack blank by planing, but no matter whether the milling cutter is used to process the small module rack or the planer is used to process the large module rack , in the processing process, single rack blanks are processed one by one, and the processing efficiency is very low. Therefore, multiple rack blanks are installed on the rotating cylindrical worktable at the same time, so that the processing efficiency is improved. This cylindrical table must also be ground or planed with a milling cutter, and the milling cutter must work intermittently

Embodiment Construction
[0016] See figure 1 ~5, a rack processing equipment, which includes a machine tool base 1, a worktable 2 arranged on the machine tool base 1, a rack that can be slidably arranged on the machine tool base 1 and close to the worktable 2 along the X-axis direction Processing head 3.
[0017] The worktable 2 is cylindrical, and is rotatably arranged on the machine tool base 1 around its own axis. The axis of the cylindrical worktable 2 extends along the X-axis direction. The outer circumferential wall of the worktable 2 is provided with a A plurality of installation grooves 5 for installing the rack and extending along the X-axis direction, the plurality of installation grooves 5 are distributed along the circumferential direction of the table 2, and the distance between two adjacent installation grooves 5 is smaller than the rack to be processed In this way, multiple pre-machined racks are installed in different installation grooves 5, so that multiple racks can be processed at ...

The gear rack machining apparatus includes one machine tool seat, one work bench on the machine tool seat, and one gear rack machining head capable of sliding in the X direction. The cylindrical work bench capable of rotating around its axis in X direction is set on the machine tool seat, and has several gear rack installing slots extending in X direction and distributed in the circumference direction of the work bench. The gear machining head includes fixing base, cutter seat on the fixing base for Y direction feeding, and at least one upper cutter and one lower cutter distributed in Z axis direction, with the distance between the upper cutter and the lower cutter being not greater than the width of the gear rack under machining. The present invention has high cutting precision and long cutter life.
Description
technical field [0001] The invention relates to a rack processing equipment. Background technique [0002] In the prior art, the machining method of the rack uses milling cutters of different standards to directly grind the raw materials. For racks with small modules, this processing is relatively simple and convenient; but when the module of the rack increases , it is not suitable to use the milling cutter to directly grind the teeth, so people usually use the planer to plan the rack blank, but whether the milling cutter is used to process the small module rack or the planer is used to process the large module rack , In the process of processing, the single rack blanks are processed one by one, and the processing efficiency is very low. For this reason, multiple rack blanks are installed on the rotating cylindrical worktable at the same time, so that the processing efficiency is improved. This cylindrical table must also be ground or planed with a milling cutter, and the m...
