Abstract

PURPOSE:To make end deburring for a wide variety of gears performable with one unit device in a simple program change alone, by expanding an interval between deburring discs wide, and varying the expanded width automatically in a manner conformable to tooth width and form. CONSTITUTION:A width expanding body 45 is attached to a coupling plate 43, and disc holders 26 and 27 are attached to holder holding plates 19 and 20. With the smallest gear in tooth width among gears WA-WD as a criterion, the width expanding body 45 is moved so as to cause a deburring disc 61 to come into contact with the side of the gear. At the time of deburring, it is carried out by resilient force of a coil spring 60. Therefore, deburring can be done so efficiently by only adjusting an opposed interval between two deburring discs according to gears different in technical data.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gear end face deburring disk device, and in particular,
In a gear chamfering device that chamfers the end face of a gear tooth by pressing and rotating a toothed chamfering tool on a cylindrical gear, it is possible to simultaneously deburr and chamfer the end face of a gear for various types of cylindrical gears. This invention relates to a gear end face deburring disk.

[Conventional technology]

Conventionally, a toothed chamfering tool was used to apply pressure to the tooth end face of a gear to chamfer it and also remove burrs at the same time.
For example, Japanese Patent Application Laid-Open No. 54-15596 discloses a tool shown in FIG. 9, which is capable of continuous machining when the gears to be machined have the same face width, outer diameter, and shape. However, when machining gears with different face widths, outer diameters, and shapes intermittently, stop the equipment each time and use a toothed chamfering tool that matches the gear to be machined. This is a tool that can be replaced with a tool equipped with a pair of deburring discs, and other than this, several types of equipment are installed depending on the type of gear.

[Problem that the invention seeks to solve]

The conventional deburring disk device described above is suitable for deburring gears with the same specifications, but when machining several types of gears with different specifications, especially when machining gears with a small number of processing rods. , it is necessary to stop the equipment and replace the deburring disk every time the number of machining ronds is completed, and compared to the improvement in machining efficiency of the machine, the time required to stop the equipment due to the replacement of the deburring disk is reduced. The loss of target was extremely large, and in some cases, even the efforts made to improve the performance of the equipment were wasted. On the other hand, installing a device for each gear to be machined with different specifications requires a large amount of factory space, resulting in large equipment investment and personnel costs.

Furthermore, in the tool shown in FIG.
To schematically illustrate the last gear), the first
As shown in Figure 0, there was a drawback that several types of deburring devices had to be installed depending on each gear.

During deburring, the deburring disk D is held pressed against the gear end face of the gear by an elastic fluid or a rigid device.1 However, in the state before deburring, the deburring disk D is naturally larger than the tooth width of the gear. The gap between the two is narrow as shown in Figure 8 (A), and in order to widen this, a deburring disk D is used to easily introduce the gear, as shown in the tool shown in Figure 9. A slope V is provided on the side where the end face of the gear is cut, but when the machined gear is deburring the end face WC+ of the shafted gear W in Fig. 10 where the gap between the gear WB and the gear WC is narrow. , the thickness of the deburring disk also becomes thinner, and if a slope V is provided in this thin area, that part will become even thinner and will not be damaged or distorted by hitting the burr protruding from the end face while introducing the gear or deburring it. There were times when I did something like that.

The deburring disk always returns the slope drawn into the application point slope V to the load side after the finishing cycle. That is, if the slope V were stopped at an arbitrary position, the cutting edge of the deburring disk would hit the outer periphery of the tooth of the gear to be machined when the next cycle started, resulting in damage to the gear. In order to eliminate this drawback, each deburring disk device had to be equipped with a device for stopping the slope V in a fixed position.

Furthermore, if a slope V is provided in order to widen the deburring disk, this part may be damaged, resulting in a defective machined gear, or if the gear is used in a distorted state, the cutting edge on the outer periphery of the deburring disk may be damaged on the end face of the gear. If the parts of the deburring disk do not hit uniformly, especially if a spring is used as a pressing means for the deburring disk, the vibration of the spring will also be added, and the cutting surface will have lines due to chatter, making it impossible to machine the finished surface uniformly. It ran out and had to be replaced within a short time. It goes without saying that in order to make the finished surface uniform, it is important not to use a deburring disk that is distorted, but it is also possible to remove burrs by increasing the contact area of the deburring disk with the end surface of the machined gear. This is because the part that is in uniform contact with the end surface without being cut acts as a stopper to absorb the vibration of the spring and the deflection of the deburring disk during cutting, and to regulate the depth of cut for deburring. .

The above-mentioned Japanese Patent Application Laid-open No. 54-15596 and Utility Model Application No. 1987-
In No. 66528, in order to simultaneously deburr both end faces of a machined gear, the cutting surfaces of the deburring disks are placed facing each other and connected on the same axis. For this reason, in order to increase the contact area of the left end surface of the machined gear with the shape shown in Fig. 8, the center-to-center distance of the left deburring disk may be set on the same plane or on different planes. I couldn't adjust it to get closer.

[Means for solving problems]

The present invention solves the above problems, widens the disc spacing without applying the processed gear to the deburring disc, and automatically changes the width according to the tooth width and shape, making it easy to use one device. This device was developed with the aim of providing a deburring disk device that can deburr the end faces of various types of gears during setup changeover work. Two disc holders are vertically mounted on the saddle with suitable supports, and deburring discs are attached to both disc holders so that they can rotate and move back and forth through the disc supports, and the cutting blades of both deburring discs are attached. A gear characterized in that its surfaces are configured to face each other, a widening body is interposed between the two facing deburring disks so as to be able to move up and down, and the gap between the two facing deburring disks is widened by sliding contact of the widening body. End surface deburring disc device.

(2) The disk holder has a disk support fitted into a horizontally oriented fitting hole in the holder part so as to be rotatable and movable forward and backward, and a coil spring is installed inside the fitting hole to push the disk support outward. The gear end surface deburring disk device according to item 1 above, characterized in that the device is configured to spring back and has a deburring disk attached to the disk support.

(3) The gear according to item 1, wherein the widening body has a multi-step tapered shape with a small lower edge, and protruding bodies are provided on both sides to widen the disc facing distance. End surface deburring disc device.

(4) Items 1 and 2 above, characterized in that the pair of disc holders are each attached at different heights relative to the saddle, and are each attached with a disc having a different outer diameter via a disc support. A gear end face deburring disk device according to any one of Items 1 and 3.

(5) The pair of disc holders is characterized in that at least the disc shaft of the integrated disc holder is arranged in a twisted position with respect to the axis of the gear to be machined. A gear end face deburring disk device according to any one of Items 2, 3, and 4.

It was configured as

[Operation] The present invention having the above structure operates as follows. The machining column is arranged on the bed of the chamfering machine so as to be able to slide in the left-right direction and the front-back direction when viewed from the front, and is arranged next to the back of the headstock. This allows the processing column to move back and forth and left and right in accordance with the position of the gear to be processed which rotates together with the main shaft.

The saddle attached to the processing column can be moved up and down according to the size of the gear to be processed (the height of the circumferential edge of the half-ring gear).

The disc holder is attached to the saddle via a support so that its position can be adjusted vertically and horizontally, and a disc support is attached to the holder so that it can rotate and move forward and backward, and a deburring disc is attached to the disc support. Two deburring disks are arranged with their cutting surfaces facing each other, and a coil spring is attached within the disk support so that they approach each other in opposite directions. Therefore, by lowering the saddle and inserting the gear to be machined between the opposing deburring disks, the burr on the end face of the gear can be removed.

On the other hand, the widened body interposed between the two opposing deburring disks is lowered by the operation of the cylinder, and its lower end periphery slides against both the deburring disks. Because it is tapered, it is possible to widen the opposing gap between both deburring disks, and when the opposing gap increases, the workpiece gear is inserted, so a gear with a width less than this opposing gap can be inserted. As the widening body rises, both disks approach each other in opposite directions, that is, they come into sliding contact with the end face of the gear to be machined, and deburring can be performed.

The present invention having the above structure operates as follows.

When machining the cluster gear W shown in FIG. 1, it is necessary to consider the shape of the widened body 45 and the machining order. In other words, since the gap between gear WB and gear WC is the narrowest, if you try to remove burrs from both end faces of gear WC first, the burr or gear will be removed when gears are cut on the end face WB+ of the adjacent gear WB, which has a larger outer diameter. Since chips that do not come off are protruding, when the thin deburring disk 61 descends to remove burrs, it will hit the burrs or chips and be damaged or distorted, so it is necessary to deburr the gear WB first. There is. No. 1 for deburring end face WC1 of gear WC
The shape of the step block 45A is such that a step is provided on the left side as shown in FIG. Adjust so that it is located approximately in the center of the gap between and gear wc.

Gear WC (7) Side WC2 and each gear WA, WB, WD
Although the tooth widths are not the same, since the maximum difference is small, the width of the side face WC2 is widened by the right side of the first stage block 45A, and the other gears are widened by the second stage block 45B. The amount of widening (dimensions) is such that when the gear is widened based on the gear with the largest tooth width, there is an appropriate gap to avoid being hit by chips protruding from the sides during gear cutting. Attach the widening body 45 to the connecting plate 43 and attach the disc holder 2.
6.27 to the holder holding plate 19.20, and each gear W
When the deburring disk 61 is brought into contact with the side of the gear with the smallest tooth width in the A-WD as a reference, there is a gap between the bushing 52 and the snap ring 62, and when deburring, the coil spring The long hole 23A of the holder holding plate 19.20 is
~23D, adjust the position and fix to the mounting plate 15 with bolts.

Chamfer and deburr the gears WA and WB using the chamfering machine 70.
, WC, and WD, the corresponding chamfering tool 82 is rotated clockwise every 90 degrees for indexing.

The shafted gear W is attached between the main shaft 74 and the center 75, the processing column 1 is advanced in the direction of the gear WA, the corresponding chamfering tool 82 is engaged, and the main shaft 74 is rotated to start chamfering by pressing. At the same time that a response command is sent to the proximity switch 41 in advance, the hydraulic cylinder 29 is actuated and detected by the detector 36, and the deburring disk, which is being widened by the second stage block 45B, is started by the motor 6 and moved to the deburring position. After descending, a response command is sent to the proximity switch 39, and at the same time the hydraulic cylinder 29 is actuated and detected by the detector 34, and the widening body 45 stops at the rising end.

The deburring disks 61, 61 sandwich the gear WA by the elastic force of the coil spring 60, and while rotating, cut and remove the burrs protruding from the side surface during gear cutting and chamfering.

When the set time has elapsed, a response command is sent to the proximity switch 41, and the hydraulic cylinder 29 is activated at the same time to widen the deburring disk 61, 61 to release it from the gear.
Start the motor 6 and raise the deburring disk opening/closing device A. Subsequently, the processing column 1 is moved back.

Next, in order to process the gear WB, the turret 83 is rotated at 90°.
Rotate the turret clockwise to direct the chamfering tool 82 toward the gear WB and stop rotating the turret.

Subsequently or simultaneously, the processing column 1 is moved in the X-axis direction to a position where it meshes with the gear WB, and then the column 1 is moved to the position where it meshes with the gear WB.
direction, the chamfering tool 82 is engaged with the gear WB, and the motor 6 is started with the deburring disk 61.61 widened in the same state as when it was raised, and the deburring disk 61.61 is moved forward.
61 is lowered: The processing cycle is repeated below.

Next, only to widen the width when deburring the gear WC, before lowering the deburring disk device A, a response command is sent to the proximity switch 40 to activate the hydraulic cylinder 29, which is detected by the detector 35, and the first stage block is 45A comes into contact with the protruding portion of pin 59, and the deburring disk is made narrower than the widening of second stage block 45B and lowered.

In this way, the deburring disk 61 is connected to the gear WB and the gear WC.
Even if the gap is narrow, the gear WB can be lowered to the deburring position without interfering with the gear WB during its descent, and the deburring process can be performed.

After finishing machining the gear WD, each device returns to its original position and completes all cycles.

The present invention is not limited to the above configuration.

Of course, it is also possible to process single gears other than those with shafts.

The opposing distance between the two deburring disks can be freely adjusted, and several types of gears with different specifications can be machined simply by adjusting the height of the deburring disks and the opposing distance. For example, as shown in Fig. 8, the left disk support and the right disk support are different in height, but the opposing surfaces of both disks are also tilted from vertical parallel to vertical so that the gears can be rotated. An inclined contact can be made with respect to the side end surface (vertical). The above-mentioned widening body is not only on one side, but also on one side.
Steps can be formed on both sides, and three steps can be formed.
It can also be formed into four stages.

Each of the motors may be an electric motor or a hydraulic motor. The cylinder may be of a type other than hydraulic.

The arrangement of each unit can be freely changed and is not limited to the illustrated configuration.

〔effect〕

Since the present invention is configured as described above, it has many excellent effects as follows.

A. The dual deburring discs are supported by a holder with their cutting surfaces facing each other, and are biased in opposite directions by the elastic force of a spring. Because it is flexible, it is possible to widen the opposing spacing between the two standard deburring disks depending on the type of gear with different specifications, and then sandwich the gear to be machined between them to perform deburring. The device can efficiently deburr many types of gears.

B. If the width cannot be widened with one multi-stage block, the widening body can be replaced and the width can be easily adjusted.

The shape of the C0 gear allows the axes of the left and right deburring disk devices to be arbitrarily adjusted, allowing disks with different outer diameters to be easily installed.

D. By making the left and right holders symmetrical or asymmetrical depending on the shape of the processed gear, the distance between the centers of the deburring disks can be set on the same plane or on different planes.
can be parallel or non-parallel,
A gear whose deburring surface is slightly inclined (for example, the first
WE> in the figure can also be processed by aligning the axis of the deburring disk and the axis of the processing gear to a twisted position.

E. A vertically movable burr removal device is installed on the chamfering machine to move the deburring disk device toward and away from the machine according to the size of the outer diameter of the processed gear, so that chamfering and deburring can be performed at the same time.

F0 This device can deburr many types of gears with different specifications, so in combination with a multi-axis head chamfering mechanism, one chamfering machine can deburr many types of gears with different specifications. Since deburring and deburring can be performed continuously at high speed, equipment costs and processing costs can be reduced.
