Problems solved by technology

[0004] Its disadvantages: 1. The calculation of gears is more complicated; 2. The number of hanging wheels with various teeth numbers must be complete; 3. The matching of hanging gears is more troublesome; 4. The coaxiality of the product is poor, and the processing accuracy is not high
The existing processing methods for spiral products can no longer meet the processing requirements. At present, there is no broaching machine in China that can pull out internal and external spiral products of various leads without mechanically replacing gears.

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] As shown in the figure, it includes: bed 1, face plate 2, servo motor 3, water pump 4, oil pump 5, control panel 6, electrical box 7, system control box 8, water pipe 9, proximity switch 10, reducer 11, gear 12. Encoder 13.

[0015] The principle of the present invention: the servo motor 3 controls the rotation speed and direction of the workpiece, the workbench uses hydraulic transmission, the broach reciprocates up and down, the encoder 13 monitors the running speed and position of the broach, and the position of the broach is fed back to the servo motor 3, The servo motor 3 adjusts the rotational speed of the workpiece again.

[0016] Due to the requirement of high coaxiality of the helical spline, first of all, the vertical broaching method with high processing quality and stable hydraulic system are used as the basis for the design. Design a fix...

Abstract

The invention discloses a numerical control hydraulic spiral vertical broaching machine which comprises a motor, a speed reducer, a workbench, a broaching tool and an encoder, and is characterized in that a servo motor is additionally arranged, the servo motor is used for driving the speed reducer, the speed reducer is connected with a gear and used for driving a flower disc, a PC (personal computer) is connected with the servo motor and used for controlling lead and adjusting rotation direction, the encoder arranged on the broaching machine is used for monitoring the broaching tool, and a position signal of the broaching tool is transmitted to the PC. The broaching machine based on the technical scheme can be applicable to large-batch production and small-batch broaching of splines with different leads, be suitable for broaching various splines with the different leads, and simultaneously enable the precision of broached products to be high.

Description

technical field [0001] The invention relates to a broaching machine, in particular to a new type of broaching machine designed for processing internal and external spiral products with various leads. Background technique [0002] Broaching machines are generally divided into inner broaching machines and outer broaching machines. The internal broaching machine is used for broaching the inner surface, such as spline hole, square hole, etc. The workpiece sticks to the end plate or is placed on the platform, and the transmission device moves the broach in a straight line, and the broach is picked up by the main slide and the auxiliary slide. The pull-out bed can be divided into horizontal type and vertical type. The former is more commonly used, can process large workpieces, and occupies a larger area; the latter occupies a smaller area, but the stroke of the broach is limited. The external broaching machine is used for broaching the outer surface. There are mainly the follow...
