Description

Technical Field

[0001] The utility model relates to the technical field of timing gear processing equipment, in particular to a processing device for timing gears of automobile engines. Background Art

[0002] Timing gears are gears that play a role in time scale positioning in mechanical devices to complete related control functions. Timing gears are introduced into the intake and exhaust systems of internal combustion engines, clocks and other local systems that have a sequential relationship to complete mechanical functions. Grooving the outer periphery of timing gears is one of the important steps in the production process of timing gears, and corresponding processing equipment is often used for this.

[0003] The prior art has the following deficiencies: In the prior art, the publication number of CN202621842U states that “the processing device for a timing gear of an automobile engine” includes: a wooden mold box, a forming template, a guide push rod, and a pedal thrust rod; the wooden mold box is movably located above the forming template, and the guide push rod passes through the forming template and is fastened to the wooden mold box; the pedal thrust rod is connected to the free end of the guide push rod; when working, after the molding sand is filled into the wooden mold box and compacted, a certain force is applied to the pedal thrust rod to drive the guide push rod, and the guide push rod pushes the wooden mold box upward to obtain a timing gear sand mold”;

[0004] The above structure improves the workpiece production quality through structures such as wooden boxes, forming templates, guide push rods, and foot-operated thrust rods. However, the structure does not improve the grooving steps of the timing gear. The traditional grooving process requires the use of a large amount of lubricating oil to assist in cutting, and most of the lubricating oil is difficult to use after mixing with metal chips, resulting in increased costs and waste of resources. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a processing device for a timing gear of an automobile engine, which solves the current problem of waste of lubricating oil resources and increased costs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a processing device for a timing gear of an automobile engine, comprising a device body, a control panel, and a motor, wherein the control panel is arranged on the outer end surface of the device body, and the motor is arranged inside the device body;

[0007] An electric cylinder is arranged on the top of the equipment body, an oil pump is arranged at the rear end of the equipment body, and an oil injector is arranged on the inner end surface of the equipment body;

[0008] The electric cylinder also includes a push rod and a milling cutter. The push rod is movably connected to the inside of the electric cylinder and extends downward to penetrate the top of the equipment body. The milling cutter is movably connected to the bottom end of the push rod.

[0009] As a preferred technical solution of the present utility model, the equipment main body further includes a sieve plate and a turntable. The sieve plate is fixedly connected to the inner end of the equipment main body below the milling cutter, and the turntable passes through the inside of the equipment main body through a columnar structure at the lower end and is movably connected to the motor.

[0010] As a preferred technical solution of the present utility model, a columnar structure protruding upward is further provided at the center position of the top of the turntable, and the top end of the columnar structure converges towards the center.

[0011] As a preferred technical solution of the present utility model, a tubular structure is further connected to the outer end face of the oil injector facing the milling cutter, and the end of the tubular structure is directly opposite to the upper end of the milling cutter.

[0012] As a preferred technical solution of the present utility model, the lower part of the sieve plate is communicated with an oil pump, and there is an internal hidden pipeline connection between the oil pump and the oil injector.

[0013] As a preferred technical solution of the present utility model, the periphery of the milling cutter is a slice structure distributed in a diffused manner, and the rotation frequency of the turntable can be adjusted by the motor.

[0014] As a preferred technical solution of the present utility model, when the milling cutter is used for the first time, a sufficient amount of lubricating oil needs to be poured in advance, and the lubricating oil is replaced after being recycled multiple times.

[0015] Compared with the prior art, the present utility model provides a processing device for an automotive engine timing gear, which has the following beneficial effects:

[0016] In this processing device for an automotive engine timing gear, by setting an electric cylinder, an oil injector, a sieve plate and a milling cutter, when the equipment processes the timing gear, the operator controls the electric cylinder, the motor, the oil pump and the oil injector through the control panel. The operator first places the die blank of the timing gear on the turntable, drives the turntable to rotate through the motor, then pours the lubricating oil on the milling cutter, and then starts the electric cylinder. The electric cylinder controls the milling cutter through the push rod and makes the milling cutter move up and down repeatedly. During the up and down movement of the milling cutter, the edge of the timing gear is cut. The lubricating oil diffuses to the edge of the milling cutter as the milling cutter moves up and down and finally drops on the sieve plate. The metal chips cut by the milling cutter are blocked by the sieve plate, and the lubricating oil flows into the lower part of the sieve plate and is transported to the oil injector by the started oil pump. The oil injector sprays oil on the milling cutter through the pipeline at regular intervals until the timing gear is processed during continuous rotation; through the above process, the equipment can continuously collect the dripping lubricating oil during the processing of the timing gear, screen out the metal chips, and then reuse the recycled lubricating oil, thereby saving the required cost during the production process.

The push rod 401 is movably connected inside the electric cylinder 4 and extends downward through the top end of the equipment main body 1. The milling cutter 402 is movably connected to the bottom end of the push rod 401.

[0026] In this embodiment, the equipment main body 1 further includes a sieve plate 101 and a turntable 102. The sieve plate 101 is fixedly connected to the inner end of the equipment main body 1 below the milling cutter 402. The turntable 102 passes through the inside of the equipment main body 1 through the columnar structure at the lower end and is movably connected to the motor 3; A columnar structure protruding upward is also arranged at the center position of the top of the turntable 102, and the top end of this columnar structure converges towards the center;

[0027] Specifically, as Figure 1 shown, the columnar structure protruding upward from the center of the top of the turntable 102 can penetrate through the timing gear and fix the timing gear to prevent it from shaking during the machining of the timing gear;

[0028] In this embodiment, the outer end surface of the oil injector 6 facing the side of the milling cutter 402 is also connected with a tubular structure, and the end of the tubular structure is directly opposite to the upper end of the milling cutter 402; the lower part of the sieve plate 101 is communicated with the oil pump 5, and there is an internal hidden pipeline connection between the oil pump 5 and the oil injector 6;

[0029] Specifically, as Figure 3 shown, the tubular structure is inserted into the oil injector 6, and its outer end is aligned with the upper part of the milling cutter 402, which can ensure the precise supply of lubricating oil;

[0030] In this embodiment, the periphery of the milling cutter 402 is distributed in a diffusion-like surrounding sliced structure, and the rotation frequency of the turntable 102 can be adjusted by the motor 3; when the milling cutter 402 is used for the first time, a sufficient amount of lubricating oil needs to be poured in advance, and the lubricating oil needs to be replaced after being recycled multiple times.
