When the bearing 31 contacts with a bolt 39, the return of a body 7 is suppressed, and the shaft 25 is revolved in the B direction by the reaction force, and the chips 4 in the chip catching part 8 are pulled-down.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing chips from a workpiece produced by a metal cutting machine.

[Conventional technology]

Traditionally, chips from metal cutting were removed manually,
In order to achieve unmanned cutting, a conveyor is installed below the workpiece and the chips are dropped onto the top of the workpiece to be removed. Under Shido, unmanned chip removal is the most difficult problem to solve.
c. If the chips were dropped onto the conventional conveyor, the chips could not be removed because they would not fall onto the workpiece f. Set,
The 9 chips entangled in the cutting tool cause 4 losses to the cutting tool, and the S
1. This can lead to sticking, deterioration of machining accuracy, and intrusion between the cutting tool and the workpiece. In view of the above, the present invention provides a method for unmanned metal cutting by removing accumulated chips from the workpiece f and the cutting tool K. The objective is to provide a chip removal fcm' that can be highly effective in reducing the amount of chips.

The main body 7) has a forfeiture that rotates the main body (7) in the same direction (L).
The sea urchin screw rLt chip hooking part 181 is provided, and when a force is applied to prevent the chips (4) of the main body (7) from moving forward F' to the chips (4), the main body (4) is rotated in the forward direction and is separated from the chips t4J. When a force that prevents the rotation in the direction is applied, the force rotates in the opposite direction. A llJ control means is provided, and the chip is further caught on the chip hooking part (8).
The t-chips (4) are provided with a chip scraping piece (6) that is retained when the main body (7) rotates in reverse, and is located at the 7+: point.

[For production]

When rotated in the forward direction to T1, the chip hooking portion (81 μm of chips +4) will be caught on the upper part of the screw n which rotates the positive rotation direction of the moth wood (7) in the same way. Next, after reviving the Molecular Rhinoceros (7) and reversing the rotation, it turns out that the 42 end is attached to the 9-chip hook 181, and the 42 end is the main body (71's forward rotation force [also known as the screw thread in the machining screw), and the hook is 181. Scraps (4)
When the scrap scraping piece (6) engages with the scraper (6), the scraps are scraped off from the scrap hook (18).

When the chip catching hook part i81 on the forward cutter of the main body (71) comes into contact with the chips (4), the forward movement Fμ of the main body (7) will be blocked. ).Then, the chips will be caught in the above-mentioned machining tool.181 VC machining will cause the chips to be caught in the workpiece (14).

The outer circumference 1cH wire (11) of @ part f91 is wound in a spiral that corresponds to the positive rotation of shaft part t91, and the e product (
At 91, it is inserted into nine holes and is hard. Maku, hat part (9
In the first part of the drive, which has a JII 4μ socket-shaped female screw aα, a μ spiral gear circle is fitted on the motor shaft α3 in the drive.

With a cover firmly attached to the front end of the ψ6ja full-length cutting motor α,
It covers the upper blade, front part, and both sides of the spiral gear circle.

Then, the shaft receiver 1Qf9icμ spiral gear shaft holder is inserted and supported in the rotational position and axially equivalent (rolling) self-pressure. Spiral gear 7 gear 7 teeth 5i% circumference lCm It is a long spiral gear with a cedar ring and a diameter of 72 knees.It is exposed from the exposed part of the shaft receiver + $0119, and the spiral gear circle and 1I111 are exposed at the 7'C part. Both ends of the Loss Spiral Gear Shirt 128, which engages in a straight fork shape, are screwed together (N1 chips) 4) The @ part (9) is inserted into the socket-shaped female thread part 1121 of the @ male thread part. 〇In addition, it is a 281rc locking nut. Further, the outer periphery a of the spiral gear shaft protruding from the shaft receiver QIiη1 to the chips 14+- is covered with a silver elastic bellows cover. Here, the shaft receptacle is placed on the proximal end of the bellows cover, and the ring body edge is fitted onto the proximal end of the bellows cover so that the eyes meet.

On the outside of the cover J51 on the opposite chip F4) side @d01cμ spiral gear shaft 4 and bearings 3υ and t are covered with an angle iron (to) with the top edge facing up. The mountain is provided in the axial direction of the spiral gear shaft G in the steel (end) direction (C bath length hole is swarf + 4)N. Then insert the long hole rope of Yamanashi Steel C34 and the anti-chip (near the end on the 4j side and the VC head gA5% 161 @ how many bolts 381 (to)) from the back and nut □ゞ14Q14) 11c work. It is fixed at n. 9. Place the bolts between the heads of each country on the bearing 31, and reciprocate the outer end of the bearing l311 on the gills shown in Figures 3 and 5. 〇7, which limits the fI range, a μ plate-shaped chip scraping piece (42) is attached to the bottom surface of the Gengen motor (9) at the chip hooking part 111+ at the return cutting position. I'm here.

Next, the driving wJ circuit of the chip removing device 16) will be explained based on FIGS.
1! 1 possibility will be cut back. If you connect it with a timer and perform it at a fixed interval of 1 temple, 7t! 7. A switch that cuts chips (for example, if a proximity switch is installed near the workpiece (3) and chips tt+ increases and approaches the workpiece, connect it to Ding n.li construction.

Note that (s2) is a μ hand switch.

When the king switch (S1) is turned ON, the relay (R1
)・(R2) is energized and becomes state C in Figure 8, and the first motor (9) hidden direct current 'a 掠Ω) is energized to become 1 first wave n 0.
The rotation of the spiral gear I by this zero-stroke motor is transmitted to the spiral gear shaft.

Then, spiral gear shaft j island bearing 31
1 is moved between the heads of the bolt in the elongated hole side until it comes into contact with the chip (4). Here, the length of the bolt (μ) chip hooking portion (81) on the elongated hole side is determined as appropriate depending on the distance it takes to hook the chip (4).

Then, the bearings all come into contact with the head of the bolt and exert a reaction force that prevents the spiral gear shaft G from moving in the axial direction, that is, the X body (7) from moving forward. When warping, since it is a spiral gear of a spiral gear shaft Gμ machine, it will rotate when subjected to axial opening force.
The chip hooking part 181 IC is connected to the rotating μ-axis part (9)
That's what I say. This direction of rotation is the forward rotation direction when the circuit is connected as shown in Figure 8.
VC is obtained by hooking the tip of the 1μ tip onto the tip of the main body (7), which has a spiral shape in the same direction as the screw (4).

When the 7th rear main switch (1) turns OFF, the relay (R
1) Although d is demagnetized, relay (R2) μ is self-holding and is in the energized state, so it becomes the state VC in FIG. After %F9r time, time switch (BTR) opens (time relay (
TR) is excited. In the circuit state shown in FIG. 9, the μ drive motor (6) uses the hidden DC' as a source, and the VC rotates in the opposite direction to the circuit state shown in FIG. Then, the spiral gear α begins to rotate in the opposite direction, and the chip hooking portion (8) stops its forward rotation, and the chip (4)
hook and return. When the bearing @υ at the end of the spiral gear shaft comes into contact with the force β of the head of the bolt 4 at the end of the angle steel shaft, and a reaction force acts to block the main body (7) OaLak, the spiral gear shaft 6μ reverses. Rotate (in the direction of arrow B in Figure 1), and the chip hooking part rotates 181% in the opposite direction. The chip scraping piece (6) overflows into the chip hooking part 18) which rotates in the reverse direction with this repulsion device.
When the chip is caught rt, 7tH, the chip (4) is caught, and the chip is caught in a1B+j (the tip or forward rotation direction is the same (the gills are rounded with a spiral shape, and the chip (4) is pulled out in the form of a drop). The IC will be scraped off.At this time, the 11il
F! The spiral wire 1111 on the outer periphery of 1A191 also has chips (4
) will contribute to the decline. After that, press the time switch (and T
R) opens and returns to the state shown in diagram m7. In addition to this, unmanned removal of LD, chips + 4) is ci! At'L, but
The implementation of the present invention can contribute to unmanned operation with the following effects.

In other words, is the workpiece 131' cut out? Part-Time Job,
If there are a lot of chips in the 2+ and υ−, the chips will be present before the bearing 311 at the end of the spiral gear shaft (c) comes into contact with the screw heads of the bolts in the long holes of Yamanashi Koso. The hook portion 181 comes into contact with the chips (4) and prevents the X body (7) from moving back and forth. Then, the spiral gear shaft j
rotates in the forward direction because it receives an axial force n, rcc,
Chip catching R1g1% forward rotation From here, chips (4) will be caught in the same way as described above. Ding, that is,
Chips (4) Regardless of the weight, the chips can be caught (s,
Chips (4) can be caught without receiving m negative R'ft.

Part of the workpiece 131 and pie of chips 14)! '+21
What's wrong with the body (7) is so bad IFlrz
Chips caught 11; capital 18+ is pulled by the chips (4) and blocked. In this case, the spiral gear shaft 25μ axis will be supported by all forces, so it will rotate in the opposite direction, and the chip hooking part (81%) will rotate in the opposite direction. Then, the F chip hook part IGL gets entangled with the workpiece +31, etc., and when it stops being pulled by the T chip +47, it returns to the main body (7) again, and the above-mentioned process is carried out. Sea urchin revenge! El] Chips (4) μ at the boundary position
It will be scraped off. In other words, even if the chips (4) are heavily entangled with the workpiece (31 etc.), the chips (4)
), which poses only nine obstacles to unattended removal work.

Next, Fig. 1O rcX: Regarding the t implementation sequence with different designs,
Differences from the above implementation row will be explained below, and descriptions of the same items will be omitted.
In the above example F, the shaft part (9) is also formed of a small rod material.
The connecting μ shaft part (91) and the body cutting part are connected via a flexible wire decoy of approximately the same size. In other words, the male screw thread at the tip of the spiral gear shaft ω I261rC is a tapered wire. jlIl!l Shape with a hole, the male threaded part iV

is 1! IKVj! Now connect the wire 44μ to the spiral gear shaft. And wire view a right part 1
L @ capital (9; and the drive WJ part +101 are connected to the 9 + end of the wire).Here, the wire decoy part following the -a shaft part (9) end and -f nyl is connected. 7 is a mounting tube, and a chip scraping piece (6) is attached to the set screw at the tip of the bellows cover 6 on the outer periphery of the spiral gear shaft. Instead, it is covered with a cylindrical cover η.A flexible hose t4S is fitted between the tip of the cover η and the end of the mounting tube to cover the wire t431 between them.

The chip removal model shown in Fig. 10 above is the upper model that uses a gusset to protect the area around the machining area of the metal processing machine from cutting oil and cutting when the installation space is limited. Suitable for use in Ding, wire @3
1t example, chip hooking part 181 'l body first capital (1
0) can be set to any number of 60,000 units, so the installation space can be used effectively, and Maku metal processing iso protects /
- When the protective nozzing is used, the protective nozzing can be used by simply providing a gap in which the flexible hose decoy can be inserted, so there is no problem with the protective nozzing's effect of preventing cutting oil and chips from scattering.

Unlike the one shown in Fig. 2, Fig. 11 shows the nine-cut chip hooking part 181 and the shaft part (9). The construction shown in Fig. 11 ■ is a roughly triangular shape with a hidden wire (1
1) A spiral groove is provided at two points 7'.

Note that the chip hooking part (81) does not have to be spiral-shaped, but can be machined as long as the tip is twisted so that it faces upward in the forward rotation direction of the X body (7).

9. Instead of the spiral gear α4, as shown in Fig. 12, the outer periphery of the circular plate fitted to the motor 0 of the driving motor (6) is aligned between the circular and the slanted sides. cylindrical bottle t

, the above-mentioned spiral gear α4) (changed to the 0g type and engaged with the aI type of the spiral gear shaft).

In addition, in the above implementation row, the reciprocating drive and forward/reverse rotation part of Kakubuhon (7)! To take advantage of the engagement of the spiral gear, I applied it to a single body motor (c).9;
The drive control means that rotates the X body (7) in forward and reverse directions when the force that prevents the reciprocation of the X seat (7) acts also utilizes the engagement of spiral gears, but is limited to this. Don't hide it with things that are boring. For example, regarding the reciprocating saw wJ of the X body (7), the driving bar source has a reciprocating cutting μ rack and pinion machine gt, and the rotating section f directly connected to the forward and reverse rotating cutting cutting body (7)
Each source is provided separately, and furthermore, a control device is provided using a relay or the like to perform forward, forward, temporary, and reverse rotations. Mat, round trip vJt
When the blocking force acts, the X body (7) is rotated in forward and reverse directions. Even if I tried to cut out the five (7) reverse-rotating drive motors, there would only be one. Therefore, by utilizing the engagement of the spiral gear in the above embodiment, it is possible to modify the motor (b) to perform reciprocating and forward/reverse driving. It is possible to detect the power to prevent the child from reciprocating! flat cloth'%,! There is no need to install #, the structure is simple, and it can be manufactured at extremely low cost.
The workpieces shown in Figures 13 to M17 can also be used as 1ull collection collection display 1521! Chip removal shown in Figure 1, Figure 9 of Joki No. 1
If 1B+1 is used, it is 0. Only the different parts will be explained and the explanation of the same parts will be omitted. First, the saucer shown in Fig. 14 is inserted into the male screw thread at the tip of the spiral gear shaft via J54J (6111). Not yet.

A rotation regulating piece shown in FIG. 17 is housed at the end of the spiral gear shaft together with a bearing βυ. In this case, as shown in Figure 16, the rotation regulating pieces come into contact with both sides of the Yamanashi steel shaft to limit the (2) rotation range of the spiral gear shaft. Motor 1IIIQ field toss spiral gear α4)j(
It is not directly connected, but is connected via the torque limiter structure shown in Figure M15. In front of the dork limiter structure, there was a group of 7 people, 15 people, and a protruding axis-ζ.
It has a set screw (6υ and 1 setting) for the motor α3.

A hidden male screw area is formed on the protruding turret at 161.

Spiral gear α4) The top surface of the μ motor Q4 side is hollowed out to form a recess and a cylindrical protrusion on the other end face. The spiral gear α4) Ni-concave a: (to) has a recess rL, and a protrusion between the mounting base with the (to) nine points @+
61 so as to be rotatable. 161r here! The O-ring closes the gap between the vR base μs and the concave portion of the spiral gear α4. A compression coil spring is wound around the protrusion of the spiral gear α4, and the spring is pressed against the lining of the spiral gear α4.
(To) The press fE body that presses and biases between the mounting bases through the 7-way screws into the male threaded part b1 of the protrusion between the mounting bases)
Turn! When the L image acts, the motor @a3 becomes empty and an overload field is prevented.

Then, the bearing 1 at the end of the spiral gear shaft
311 is chevron-shaped until the heads of the bolts Vc in the slotted hole head in the figure are in contact with each other until the socket J1131O workpiece (
3) shall be located below n. Also, at this time, the spiral gear shaft Qs rotates forward and the rotation regulating piece 15
If 6 + 1c construction is limited to 7 (b) rolls, saucer 15
3H The concave side is attached to the workpiece, which will serve as the upper blade.

In this process, the lathe [11's bite (21 to 21 is cut off in the radial direction and the falling workpiece (31) is caught in the saucer. At this time, a regulating piece is set at 60 rotations of the spiral gear shaft. There is a regulation δ1 between the motor @a3 and the spiral gear α and the hidden torque limiter structure 15'
Since they are connected via rIt, it is possible to prevent the initial drive motor (b) from being overloaded. Then, when the spiral gear shaft is rotated in reverse rotation, the tray also rotates in the reverse direction and the workpiece (31) can be dropped and collected.

In addition, even if you set the torque limiter structure 1151 in Figure 15 to remove the stile chips (6), there is a possibility that η1 will stick or the forward rotation will be severe when installing it in the L and catching the chips (4). In order to prevent overload of the starting motor (b).

〔Effect of the invention〕

In the chip O removal process according to the present invention, the chip has the same reciprocating part wJ and can be rotated in forward and reverse directions, and the main body has a tip or screw rL7
t- A chip hooking part is provided, and a chip scraping piece that engages when the chip rotates in reverse is provided. Move the cap to the chip position, then rotate the body forward in the X direction, and the tip will hook the chip onto the chip hook L!5, which is threaded in the same direction as the main body's forward rotation. This means VC0. Then, when the main body is temporarily initialized and then rotated in the reverse direction, the tip of the hidden chip hook part is twisted in the same manner as the normal rotation direction of the main body, so it will not be caught r'L. Scrap the chips in 9 times! When the scraps are engaged, scrape off the chips so that the scraps are hidden and the chip puller hook part η falls off. It is possible to perform an unmanned hit.

Furthermore, when a force is applied to prevent the forward and backward movement of chips from the
'llEl1MTh~'' 1~2.1 ・Ninthly, when the body is equipped with a cutting means that rotates the body in the opposite direction, if a chip caught in the body comes into contact with the chip Vc while the body is moving, the Yesterday
When Jμ is blocked, the forward rotation of the main body is caused by the initial control means at 0, which is llC. In this case, the above-mentioned chip-catching product VC2 will catch the chips. Regardless of the size of the chips, it is possible to move the chip to the appropriate position and then rotate it in the forward direction, allowing the chip to be caught without being subjected to undue stress. When you re-cut the main body after catching chips on the chip hooking point, the chips may stick to the workpiece or the cutting tool, or be pulled tightly by the chips.
If the rotation is prevented, the repulsion control means causes the main body to rotate in the opposite direction. 7 in reverse rotation, 20 in the opposite direction, and the point on the chip hook part is the same in the forward rotation direction of Mokushu (twist it to the h)
The nano-sized chips that are caught in the chip will come out from the chip hooking part. In addition, when the F chips are no longer stuck to ρ, the temporary inhibition of the Since it is a tool that can scrape off chips, it can be removed even if the chips are heavily entangled, eliminating damage to the cutting tool, deterioration of the accuracy of the workpiece, and cutting oil fires. This contributes to unmanned metal cutting.
