Description

Technical Field

[0001] This utility model relates to gear processing equipment and the field of gear precision machining, specifically to a multi-station synchronous chamfering and deburring device for gears. Background Technology

[0002] Burrs in precision gear parts often occur during the machining process, and removing burrs is very difficult. They are usually removed using deburring equipment or manually.

[0003] The efficiency of manual deburring depends on several factors, including tool selection, deburring technique skill, and the shape and size of the burrs. Generally, with tools specifically designed for deburring and proper operating techniques, manual deburring can achieve an efficiency of thousands of parts per hour. However, this method is less efficient for larger, more complex burrs, or those with special shape requirements. In such cases, automated deburring equipment is needed to improve efficiency and ensure part quality.

[0004] Chinese Patent Publication No. CN112276707A, published on January 29, 2021, is entitled "An Automatic Gear Chamfering and Deburring Device." This device, belonging to the field of deburring technology, includes a hammer, a fixing device, a working device, a cleaning device, and an adjusting device. The upper surface of the supporting device is connected to the cleaning device, the upper surface of the supporting device is connected to the working device, the side surface of the fixing device is connected to the working device, the lower surface of the fixing device is connected to the supporting device, the lower surface of the cleaning device is connected to the supporting device, and the side surface of the adjusting device is connected to the supporting device. The supporting device includes a load-bearing base plate, a load-bearing plate, a first support plate, a second support plate, and a top plate. The upper surface of the load-bearing base plate is connected to the cleaning device, the upper surface of the load-bearing plate is connected to the first support plate, the upper surface of the second support plate is connected to the top plate, and the side surface of the first support plate is connected to the second support plate.

[0005] However, its shortcomings are that the solution itself only has two degrees of freedom for adjusting the chamfer and deburring, sharing a single grinding disc. Furthermore, this solution does not involve the rotation of the gear being ground. As can be seen from the attached diagram, it can only grind one side of the gear, and it is basically impossible to process the tooth groove. Moreover, the other side requires manually flipping the gear fixed on it, which greatly affects the processing time and manpower consumption. Summary of the Invention

[0006] This utility model addresses the problem that existing automatic gear chamfering and deburring devices, which typically employ a single-station setup and while meet the needs of automated production, still suffer from low efficiency. Therefore, a multi-station synchronous chamfering and deburring device is designed that can adapt to different types of gears of the same diameter.

[0007] This utility model provides a gear multi-station synchronous chamfering and deburring device, comprising: a pneumatic chuck set on a rotating lifting base; a fan-shaped base set with the vertical axis of the rotating lifting base as the reference axis A; and several sets of chamfering and deburring devices set on the fan-shaped base; the chamfering and deburring devices are rotationally symmetrical about the reference axis A. A decelerated stepper motor is installed on the side of the rotating and lifting base to drive the rotating and lifting base to rotate at the set angle; The rotating lifting base includes at least one telescopic cylinder for driving the pneumatic chuck to lift. The chamfering and deburring device includes: at least two adjusting brackets; a chamfering machine is fixed on the first adjusting bracket, and a brush machine is fixed on the second adjusting bracket.

[0008] The fan-shaped base allows for an angled opening for loading / unloading and alignment of optional processing housings. Similarly, the fan-shaped base features elongated, arc-shaped holes to determine the position of the adjustment bracket, accommodating gears of different diameters and tooth counts.

[0009] Preferably, the chamfering and deburring device includes a second chamfering machine, which is disposed between the chamfering machine and the brush machine, and the second chamfering machine is fixed on the adjusting bracket; Let the first station be defined as the station where the gear is machined from the upper plane and the second station be defined as the station where the gear is machined from the lower plane. Then there is a chamfering machine at both stations. The horizontal distance between the first and second workstations is greater than or equal to the thickness of the gear being machined.

[0010] The number of adjustment brackets for the fixed chamfering machine or brush machine is two, and the adjustment brackets for the same machine are on the same radial line of the fan base.

[0011] Preferably, the adjustment bracket includes: a first rod body, which is vertically mounted on the fan-shaped base, and a first mounting block is provided on the first rod body; The first mounting block includes a vertical through hole and a horizontal through hole; The second rod is set in a horizontal through hole on the first mounting block, and a clamp is fixed at one end of it. The clamp is used to hold the body of the chamfering machine or the brush machine.

[0012] The processing point of the chamfering machine or brush machine can be adjusted by adjusting the circumferential rotation angle of the second rod. When two sets of adjusting brackets are used to clamp a machine body at the same time, the vertical reaction force can be effectively countered, thereby preventing the circumferential rotation of the second rod.

[0013] As a preferred embodiment, the rotating lifting base includes: a disc base, the edge of the disc is provided with teeth, a gear is provided on the shaft of the deceleration stepper motor, and the disc base cooperates with the deceleration stepper motor; A vertically mounted slide rail is provided on the disc base, and a T-shaped slider is provided above the slide rail, with the slider part cooperating with the slide rail. The telescopic cylinder is positioned between the slide rail seat and the T-shaped slider. The cylinder body is fixed to the slide rail seat, and the telescopic end is fixed to the T-shaped slider. The pneumatic chuck is located on the top surface of the T-shaped slider.

[0014] Preferably, the adjusting bracket is also equipped with an air blowing pipe, the output axis of which points perpendicular to the processing point of the chamfering machine, with the output always from top to bottom. When the entire device is placed inside an openable enclosed processing box, the air blowing pipe can blow away the metal chips during processing, and the sealed box can prevent air pollution caused by the metal chips.

[0015] For gears of different specifications, the angle of the chamfering machine and the interval between the chamfering and deburring devices are first set before processing batches. For example, a 34-tooth gear can be set with two sets of chamfering and deburring devices, rotating 180 degrees symmetrically, or with three sets of chamfering and deburring devices rotating 120 degrees symmetrically. Setting multiple sets of chamfering and deburring devices can effectively shorten the processing time. Based on the angle set by the chamfering machine within the rotation of the deburring device, the lifting and rotating of the rotating base are arranged to achieve the processing and chamfering of the upper, vertical, and lower surfaces of the gear teeth using a fixed-point chamfering machine. After processing, the teeth are then deburred by a brush machine to complete the chamfering and deburring requirements. Attached Figure Description

The controlled rotation of the speed reduction stepper motor can achieve relatively accurate rotation of the teeth of the gear being processed. A vertically arranged slide rail seat 23 is provided on the disc base, and a T-shaped slider 21 is provided above the slide rail seat, with the slider part cooperating with the slide rail seat; The telescopic cylinder 22 is located between the slide rail seat and the T-shaped slider.

Then there is a chamfering machine at both stations. The horizontal distance between the first and second workstations is greater than or equal to the thickness of the gear being machined.

[0021] The number of adjustment brackets for the fixed chamfering machine or brush machine is two, and the adjustment brackets for the same machine are on the same radial line of the fan base.

Alternatively, a clamping hole communicating with the outside can be used to clamp the rod within the through hole.

[0023] The adjustment bracket is also equipped with an air blowing pipe. The output axis of the air blowing pipe points perpendicular to the processing point of the chamfering machine, and the output is from top to bottom.

[0024] When the entire device is placed inside an openable, enclosed processing chamber, the air blowing pipe can blow away the metal shavings during processing, and the sealed chamber can prevent the metal shavings from causing air pollution. Example 2

[0025] like Figure 2 The illustrated scheme uses two adjusting brackets to simultaneously fix a chamfering machine. The intermediate plate, indicated by mark 5, allows the lower end of the first rod 6 to pass through the elongated hole on the fan-shaped base 3, securing one first rod 6 firmly with its lower end. Installing the other first rod on the intermediate plate facilitates the deployment of the two adjusting brackets.
