Description

[Detailed description of the invention] [Industrial application field] The present invention is a resin product that is injection molded using a mold.

This is an automatic deburring device that removes burrs that occur on cast products, during machining, and when cutting materials, and is especially suitable for removing burrs that occur on complex-shaped workpieces.

[Conventional technology] Conventionally, in order to remove such burrs, workers generally manually remove each product one by one, but recently this work has been partly automated. equipment is now being used. For example, a cutter or polishing tool is attached to the tip of a table that can be moved in one direction only, and is used to remove burrs from the product.

[Problem that the invention seeks to solve]

However, when a worker manually removes burrs, the work is carried out depending on the worker's skills and experience, which requires skill and increases the product cost. In addition, workers are likely to be adversely affected by this work,
Easy to get sick. Furthermore, in a device that automates the deburring work by attaching a cutter or polishing tool to the tip of a table that can only move in one direction, it is difficult to shave the product if the shape of the product is different or complex. On the other hand, if the product is not ground, there are problems such as the burr cannot be completely removed.

[Means for solving problems]

The present invention was invented with the aim of solving the above-mentioned problems and obtaining reliable deburring work, and provides a guide in which a motor 20 is fixed and a guide portion 12a is formed on a surface perpendicular to the axis. A transmission shaft 22 connected to a motor 20 is rotatably supported on the member 12, and this guide portion 1
A guide member 11 is arranged around 2a so as to cover it,
The guide member 11 corresponding to a plurality of positions divided into at least three equal parts in the radial direction of the guide part 12a is in contact with both sides of the guide part 12a of the guide member 12, and the guide part 12a is sandwiched therebetween. The support members 14 are arranged at positions facing each other, and the guide members 1
2 and the guide member 11, a plurality of spring members are interposed between the guide member 2 and the guide member 11 to elastically bias the guide member 12 so that the guide member 12 is always positioned in the center direction, and whose elastic force is freely adjustable, and further connected to the transmission shaft 22. The cutter 24 and the workpiece 40 are rotatable.
a guide roller 18 that is movable parallel to the cutter 40 at least rearward in a direction of relative movement with the cutter 40 and is rotatable;
is arranged.

[Effect]

After the work 40 is placed on the work table, the automatic deburring device moves until the cutters 24 of the deburring units 1 to 10 reach predetermined positions on the work 40. After that, when the guide roller 18 comes into contact with the work 40 and the cutter 24 starts working, the work 40 is covered by the guide roller 18.
The work table performs a preset moving operation so as to be in contact with 8. Thereby, the cutter 24 removes burrs from the workpiece 40. On the other hand, during this work, the cutter 40 is elastically biased so as to be always positioned toward the center, so if a load greater than this elastic force is applied to the cutter 24 for some reason, the cutter 24 will escape from the workpiece 40. I can do it. For this reason, other than burrs, that is, the workpiece 40
There is no shrine attached to it.

(Example) An example of the present invention will be described below based on the drawings.
In the figures 1 to 3, reference numeral 1 denotes a stand fixed to the tip of a movable table (not shown) that can reciprocate in the horizontal direction. A take-up unit 10 is swingably provided. This support pin 2 is a disc-shaped guide member 1 of the deburring unit 10.
1, and the mounting is rotatably supported by a bearing member 3 fixed to the base 1. Also, this support pin 2
One side protrudes outward, and a lever 30 is attached to the tip.
One end is fixed. This lever 30 (t!2A
7, the piston cylinder 31 fixed to the base 1 is installed.
The piston rod 32 is connected to the piston rod 32 by a pin.

Further, a deburring unit 10 having a center line perpendicular to the line connecting the pair of support pins 2 is disposed, and a guide member 12 having a motor 20 fixed to the upper part thereof is disposed within the guide member 11. It is located. This guide member 12 has a disk-shaped guide portion 12a formed on a surface perpendicular to the axis, and this guide portion 12a extends around the annular inner periphery formed by the guide member 11 and the lid 13. It is loosely fitted into the groove. A rotatable sphere 1ea of a support member 14 attached to the bottom of the guide member 11 and i13 is in contact with both surfaces of the guide portion 12a, and this support member 14 supports the disk-shaped guide portion 12a in 6 directions. They are placed in equally divided positions. Note that in this embodiment, the support member 14
are arranged above and below with the guide portion 12a in between, and at positions divided into six equal parts, but it is sufficient that they are divided into a plurality of at least three equal parts. Further, the guide portions 1 in the respective radial directions of the positions where the support members 14 are disposed.
A compression spring 15 is necessarily interposed between the outer peripheral surface of the guide member 2a and the inner peripheral surface of the guide member 11, and the elastic force of the spring 15 is applied to the guide member 11 that supports one end of the compression spring 15. An adjustment screw 16 that allows adjustment is screwed together. This allows the guide member 12 to move parallel to the center of the guide portion vJ11.

Further, a transmission shaft 22 rotatably supported by the guide member 12 is connected to the rotation shaft 21 of the motor 20, and the transmission shaft 22 is connected to an input of a speed increasing rotation means 23 provided below. ! 1i (l123a) is connected. This speed-increasing rotation means 23 is composed of a planetary gear +a (not shown), and the output shaft 23b of this speed-increasing rotation means 23
A cutter 24 having teeth formed on the circumferential surface is fixed to the cutter 24 . Further, a guide pin 25 is provided on the case 27 of the speed-increasing rotation means 23, and this pin 25 engages with a guide plate 26 fixed to the bottom of the guide portion (212) to rotate the case 27. A mounting member 17 is fixed to this case 27;
A support 7-m 19 is attached to the support 7-m 19 for rotatably supporting a guide roller 18 that prevents the cutter 24 from coming into direct contact with the work 40 when the cutter 24 removes burrs from the work 40. As shown in FIG. 5, this support arm 19 has a long hole 19a formed therein, and by moving the support arm 19 within the range of this long hole 19a, the guide roller 18 can be moved parallel to the cutter 24. and
By fixing this with the fixing screw 19b, the guide roller 18 can be placed at an arbitrary position.

Furthermore, this guide roller 18 is configured to contact the workpiece 40 at the rear in the direction of relative movement of the cutter 24 with respect to the workpiece 40, and one of the guide rollers 18 disposed on both sides with the cutter 24 in between is, for example, the ninth As shown in the figure, when acting on the outer circumference of the ring-shaped work 40,
The other guide roller 18 comes into contact with the inner circumference of the ring-shaped workpiece 40 when acting on it.

Next, the operation of this embodiment will be explained. Ring-shaped work 4
0 is placed on a work table (not shown), a movable table (not shown) with the deburring unit 10 fixed to the tip is operated to move the deburring unit 10 to a preset position. move it. Thereafter, as shown in FIG. 4, the inclination of the burr removal unit 10 is adjusted by operating the piston cylinder 31 in advance so as to be substantially perpendicular to the inclination direction of the burrs on the workpiece 40. For example, as shown in FIG. 6, when the burr is formed almost horizontally, the cutter 24 is set almost vertically, and as shown in FIG. When the cutter 24 is tilted toward the burr, the piston rod 32 is lowered to tilt the deburring unit 10 so that the cutter 24 is approximately perpendicular to the burr. On the other hand, as shown in FIG. 8, when the burr is curved diagonally upward, the piston rod 32 is raised and the burr removal unit 10 is tilted in the opposite direction, and the cutter 24 is attached to the burr. On the other hand, adjust it so that it is almost vertical.

After this adjustment is completed, when the motor 20 is driven, the cutter 24 rotates, and at the same time, the work table is moved in a predetermined direction, that is, as shown in FIG. The guide roller 18 starts rotating in a direction rearward with respect to the cutter 24.

As a result, burrs on the circumferential surface of the workpiece 40 are removed.

Further, even if for some reason other than the burr on the workpiece 40, that is, a part of the product reaches the cutting position of the cutter 24 during this operation, the deburring unit 10 can escape by a predetermined amount.

Furthermore, if a burr is formed in a direction different from that of the work 40 on which the work is to be performed, operate the screws 1 to 31 in the same manner as described above to remove the burr from the cutter 24. By readjusting the angle and rotating the cutter 24, the burr can be removed.

Moreover, the position of the guide roller 18 that rotates in contact with the workpiece 40 can be adjusted by simply adjusting the fixing position of the support arm 19 fixed to the member 17 with the fixing screw 19b.
This is possible by loosening the fixing screw 19b, moving the support arm 19 along the elongated hole 19a, adjusting it, and fixing it with this screw 19b.

(Effects of the Invention) As is clear from the embodiments described above, the present invention is such that the motor 20 is fixed and the guide portion 12 is mounted on a plane orthogonal to the axis.
A transmission shaft 22 connected to a motor 20 is rotatably supported on the guide member 12 formed with a
A guide member 11 is arranged around the guide member 12 so as to cover the guide member 12, and the guide member 11 is placed in a position where the guide member 12a is divided into at least three equal parts in the radial direction of the guide member 12a. Supporting part treetops 14 are disposed at opposing positions so as to be in contact with both surfaces of the guide member 12a, and elastically biased so that the guide member 12 is always located in the center direction between the guide member 12 and the guide member 11. A plurality of spring members such as a plurality of compression springs 15 whose elastic force can be adjusted are interposed, and the cutter 24 is connected to the transmission shaft 22 and is rotatable at least rearwardly in the direction of relative movement between the rotatable cutter 24 and the workpiece 40. A guide roller 18 is arranged which is movable parallel to 24 and rotatable.

In this way, since there is no need for an operator to manually apply direct manual work to the workpiece to remove burrs, the cost of the product is reduced and unmanned operation is also possible. Furthermore, even if there is some variation in the dimensions of the workpiece, the center line of the deburring unit can be moved parallel to the guide member while maintaining a perpendicular state, so that burrs can be reliably removed from the workpiece. Furthermore, since the cutter is not in direct contact with the workpiece, significant effects such as no cutting of the cutter into the workpiece can be achieved.
