In order to manufacture a roller for a crawler, first, a roller shell 10 having a cylindrical rim shape having a hollow is first manufactured, and a seal is mounted around the hollow inlet of the roller shell 10, and then the roller shell 10 Insert the shaft into the hollow. When the insertion of the shaft is completed, by mounting the collar on both ends of the shaft, the shaft is not drawn out of the roller shell 10.

At this time, the shaft is simply mounted in the hollow structure of the roller shell 10, so that the shaft can be mounted on the roller shell 10 by hand, but the seal and the collar on the roller shell 10 with a very large force. As shown in FIG. 1, a separate seal indenter 200 and a collar indenter 300 are required.

Therefore, the crawler roller assembly line includes a roller feed means 100 for feeding the roller shell 10, a seal presser 200 for pressing the seal into the roller shell 10, and a roller shell. A collar indenter 300 must be provided to press the collar into 10. In addition, the crawler roller driving test apparatus 400 is provided at the rear end of the collar presser 300 so as to check whether the crawler roller completed until the collar presser is normally rotated.

The crawler roller conveying means 100 is not only configured to supply the roller shell 10 to the seal indenter 200, but also rotates the roller shell 10 about a vertical central axis to perform work. It is configured to supply the roller shell 10 to the rotary table 180, the collar indenter 300, the test device 400 for crawler rollers.

At this time, in Figure 1, the seal indenter 200 is mounted, the rotary table 180 is mounted, the collar indenter 300 is mounted, the track roller drive test device 400 is mounted The track roller feed means 100 is provided at each point, but since the basic structures of the crawler roller feed device 100 provided at each point are the same, the roller shell as the seal indenter 200 will be described below. An orbital roller conveying means 100 for supplying 10 will be described as an example.

As shown in FIGS. 1 to 3, the crawler roller feed means 100 is manufactured in the shape of a beam having a vertical section 112 and a horizontal section 114 (that is, an 'L' beam). A pair of guide rails 110 arranged side by side to face the horizontal portion 114, a pair of mounting blocks 120 mounted on each guide rail 110, and a base member B Both ends of the fixed block 122 and the pair of mounting blocks 120 are coupled to the fixed block 122 so that only the rotation is possible, but the guide rail is coupled to the mounting block 120 in a screwing structure. It is configured to include a screw bar (130). The roller shell 10 is erected so that the central axis is horizontal, and is introduced between the pair of guide rails 110 and moved by rolling on the guide rails 110, the seal indenter 200 and the collar indenter 300. ) Are provided in pairs on the left and right sides in the width direction of the guide rail 110.

The roller shell 10 has a central axis portion protruding from the top surface of the vertical portion 112 as shown in (a) of FIG. 4 according to the type, or shown in (b) and (c) of FIG. 4. As described above, the outer diameter is transported in the longitudinal direction of the guide rail 110 by rolling on the upper surface of the horizontal part 114. When the pair of vertical parts 112 is too narrow, the roller shell 10 is a pair of vertical parts. If it is not drawn between the portions 112 and the pair of vertical portions 112 is too wide, there is a problem that the roller shell 10 is inclined or shaken in the width direction of the guide rail 110, so that stable conveyance is difficult. Therefore, the spacing between the pair of vertical portions 112 should be appropriately set according to the width of the roller shell 10.

At this time, the roller feed means 100 for crawling tracks is configured in such a structure that the interval of the pair of guide rails 110 is adjustable so that any roller shell 10 can be transported regardless of the diameter or width of the roller shell 10. The biggest feature is that it becomes. That is, the guide rail screw bar 130 mounted to penetrate through the pair of mounting blocks 120 is coupled to any one mounting block 120 in a left screw coupling structure and mounted on the other. Block 120 is coupled to the right screw coupling structure, when the user rotates the guide rail screw bar 130 between the pair of guide rails 110 in accordance with the rotation direction of the guide rail screw bar 130 The gap becomes narrower or wider. If the pair of guide rails 110 is configured to be adjustable as described above, there is an advantage that the roller shell 10 having any width can be transferred as shown in FIG. 4.

Meanwhile, when the guide rail screw bar 130 is rotated to move the guide rail 110 in the width direction, a portion of the guide rail 110 on which the guide rail screw bar 130 is mounted is moved first, so that the guide rail 110 is moved. When the rail screw bar 130 is mounted on only one side of the guide rail 110, the pair of guide rails 110 may be parallel to each other and may not be moved in the width direction. Therefore, the guide rail screw bar 130 is preferably mounted more than one on the pair of guide rails (110).

In this case, when two or more guide rail screw bars 130 are mounted, the guide rail screw bars 130 are simultaneously moved at the same speed so that the pair of guide rails 110 are moved in the width direction in a parallel state. It should be rotated, it is difficult for one operator to rotate each guide rail screw bar 130 at the same time, it is more difficult to rotate each guide rail screw bar 130 at the same speed. Therefore, the crawler roller transport means 100 is preferably further provided with a power transmission means for connecting the two or more guide rail screw bar 130 so that the two or more guide rail screw bar 130 is integrally rotated. Do. The power transmission means may be applied to any structure as long as the rotational force is applied to any one of the guide rail screw bars 130, as long as the power transmission means is equally transmitted to the other guide rail screw bars 130. For example, as shown in Figure 2 by coupling the sprocket 132 to the guide rail screw bar 130, by mounting the power transmission chain 150 to the sprocket 132, each guide rail screw bar ( 130 may be integrally rotated.

When the plurality of guide rail screw bars 130 are connected to the power transmission chain 150 as described above, even if the operator rotates any one of the guide rail screw bars 130, the plurality of guide rail screw bars 130 are integrally formed. As the pair of guide rails 110 are rotated, the pair of guide rails 110 may be parallel to each other and the distance between the guide rails 110 may be adjusted.

In addition, when only the guide rail screw bar 130 is coupled to the mounting block 120 and the fixed block 122, the weight of the mounting block 120 and the guide rail 110 is concentrated and applied to the guide rail screw bar 130 to guide the guide. Not only the rail screw bar 130 is difficult to rotate, but also the guide rail screw bar 130 may be sheared. Therefore, the caterpillar roller conveying means 100 is arranged in parallel with the guide rail screw bar 130 and penetrates the mounting block 120 so as to be slidable and is coupled to the fixed block 122 so as to allow only rotation. The guide rail slide bar 140 is preferably configured to further include.

As such, when the guide rail slide bar 140 is additionally provided, the self-weight of the guide rail 110 and the mounting block 120 is not applied to the guide rail screw bar 130 but is applied only to the guide rail slide bar 140. Since the guide rail screw bar 130 may be sheared, the guide rail screw bar 130 may be reduced, and the guide rail screw bar 130 may be more easily rotated.

On the other hand, when the guide rails 110 are arranged in a horizontal direction, the operator must directly roll the roller shell 10 or roll the roller shell 10 by using a separate power device, and the operator directly rolls the roller shell ( When rolling 10), the work speed is slowed down, and when a separate power device is used, the assembly device is not only complicated in configuration but also requires a separate power source.

Therefore, the roller feed means 100 for the caterpillar, so that the roller shell 10 can be rolled along the guide rail 110 without a separate power device, so that the height of the guide rail 110 is different in both longitudinal directions It is characterized by being inclined to one side. When the guide rails 110 are inclined in this way, the roller shell 10 seated on the guide rails 110 is rolled to the lower side (the right side in FIG. 1) by its own weight, thereby increasing the working speed as well as a separate The advantage is that no power unit is required.

5 is a perspective view of a crawler roller test apparatus according to the present invention.

As shown in FIG. 5, the crawler roller testing apparatus according to the present invention is coupled to a pair of drive shafts 420 and the pair of drive shafts 420 arranged in parallel to each other in a horizontal direction. Drive wheel 410, a driven wheel 430 having a rotation axis parallel to the drive wheel 410 and located above the point between the pair of drive shaft 420, and the driven wheel 430 is elevated It comprises a lifting unit 460 and a fixing means 450 for fixing the collar 30 of the roller seated on the drive wheel 410. When the roller is seated on the driving wheel 410, the driven wheel 430 is lowered so that the outer circumferential surface of the driven wheel 430 is in contact with the outer circumferential surface of the roller and is fixed by holding the collar 30 of the roller by the fixing means 450. After the rotation, the drive shaft 420 is rotated to check whether the roller is normally rotated.

At this time, the collar 30 is mounted on the central axis of the roller shell 10, the fixing means 450 is one type of driving wheel on one driving shaft 420 seated on the driving wheel 410 If only 410 is coupled, there is an inconvenience that the height of the fixing means 450 must be adjusted whenever the diameter of the roller shell 10 seated on the driving wheel 410 is changed.

In addition, the roller shell 10, as shown in (a) of Figure 4, the middle portion of the main surface may be in contact with the cloud, the width of the outer peripheral surface as shown in (b) and (c) of FIG. There are cases where both sides are in contact with the cloud, and if only one type of driving wheel 410 is configured to be coupled to one driving shaft 420, the number of driving wheels 410 is changed whenever the type of roller shell 10 is changed. And because the diameter must be changed, there is a disadvantage that the driving test time of the roller takes a lot.

In order to solve such a problem, the crawler roller test apparatus according to the present invention is configured such that two kinds of driving wheels 410 having different diameters are mounted on one driving shaft 420. That is, the driving wheel 410 is composed of a first driving wheel 412 and a second driving wheel 414 having a different diameter, the first driving wheel 412 is two or more on one drive shaft 420 The second driving wheel 414 is coupled between two first driving wheels 412 coupled to one driving shaft 420.

When the driving wheel 410 mounted on the driving shaft 420 is configured as described above, in the case of the roller shell 10 illustrated in FIG. 4A, the driving wheel 410 may be seated on the second driving wheel 414 to perform a driving test. In addition, in the case of the roller shell 10 shown in (b) and (c) of Figure 4 can be mounted on the first driving wheel 412 to perform a driving test bar, various types of driving wheel 410 without replacement It has the advantage of being able to drive test the rollers.

On the other hand, the driven wheel 430 should be positioned in the center in order to contact the upper outer peripheral surface of the roller shell 10 of the shape shown in Figure 4 (a), shown in (b) and (c) of Figure 4 In order to be in contact with the upper outer circumferential surface of the roller shell 10 of the shape should be spaced apart on both sides. Therefore, the crawler roller test apparatus according to the present invention may be provided with the driven wheel 430 in pairs, and may further include a gap adjusting means 440 for adjusting the distance between the driven wheels 430. The gap adjusting means 440 of the pair of driven wheel mounting block 442 and the pair of driven wheel mounting block 442, the pair of driven wheels 430 are respectively coupled to the rotatable structure Base block 444 is provided on the upper side and both sides extend downward, and the middle penetrates through the pair of driven wheel mounting block 442 and both ends are coupled to the structure capable of rotating only on both sides of the base block 444. It comprises a driven wheel screw bar 446.

At this time, the driven wheel screw bar 446 is coupled to any one mounting block in the left screw coupling structure and the other mounting block is coupled in the right screw coupling structure. Therefore, when the operator rotates the driven wheel screw bar 446 in one direction, the pair of driven wheel mounting blocks 442 are close to each other, and when the driven wheel screw bar 446 is rotated in the other direction, a pair of The driven wheel mounting blocks 442 are separated from each other. As such, the driven wheel screw bar 446 for adjusting the distance between the pair of driven wheel mounting blocks 442 according to the rotation direction is substantially the same as the guide rail screw bar 130 shown in FIGS. 2 and 3. Therefore, detailed description thereof will be omitted.

In addition, the crawler roller test apparatus according to the present invention is arranged in parallel with the screw bar and penetrates the driven wheel mounting block 442 so that the suspension is slidable, and both ends thereof rotate only on both sides of the base block 444. It may further include a driven wheel slide bar 448 coupled to a possible structure. Since the structure and role of the driven wheel slide bar 448 is substantially the same as the structure and role of the guide rail slide bar 140 shown in FIGS. 2 and 3, a detailed description thereof will be omitted.

Figure 6 is a cross-sectional view of a crawler roller test apparatus according to the present invention in which the large-diameter roller is seated, Figure 7 to Figure 9 is a sequential process of driving test the large-diameter roller using the crawler roller test apparatus according to the present invention 10 is a cross-sectional view of a crawler roller testing apparatus according to the present invention in which a small-diameter roller is seated, and FIGS. 11 to 13 are small tracks using a crawler roller testing apparatus according to the present invention. It is a longitudinal cross-sectional view which shows the process of driving test of an aperture roller sequentially.

The roller shell 10 of the shape shown in (a) of FIG. 4 is seated on a second driving wheel 414 having a relatively small diameter and positioned in the center, as shown in FIG. 6, and a pair of driven rollers. Is positioned to be driven to the center and is in contact with the upper outer peripheral surface of the roller shell (10). When the driving shaft 420 rotates in the state shown in FIG. 6, the second driving wheel 414 coupled to the driving shaft 420 is rotated and the roller shell seated on the second driving wheel 414. (10) will also rotate.

At this time, since the roller shell 10 rolled on the guide rail has inertia, the roller shell 10 may not be seated on the second driving wheel 414 and may pass over the second driving wheel 414. The roller shell 10, which has been seated on the panel, has a problem in that it takes a lot of time for the driving test because it cannot escape the second driving wheel 414 unless a separate external force is applied.

Therefore, the roller test apparatus for crawling track according to the present invention is to stably seat the roller shell 10 rolling on the guide rail 110 on a pair of driving wheels 410 to solve the above problems. Guide block 472 and guide block to block the rolling of the roller shell 10, and to push up the roller shell 10 so that the roller shell 10, the drive test is completed can be seated on the guide rail again. It further includes a cylinder 474. The guide block 472 is located between the driving wheels 410 coupled to different drive shafts 420, and the guide block cylinder 474 has the drive shafts 420 having different guide blocks 472 from each other. It serves to elevate the guide block 472 to be drawn between the driving wheel 410 coupled to.

In the state in which the guide block 472 is raised, the roller shell 10 rolling on the guide rail 110 interferes with the guide block 472, so that the pair of second driving wheels is shown in FIG. It is not seated on the 414 and is blocked by the guide roller to remain stopped.

When the guide block 472 is lowered in the state shown in FIG. 7, the roller shell 10 is also lowered and seated on the pair of second driving wheels 414 as shown in FIG. 8. At this time, the driven wheel 430 is also lowered to be in close contact with the upper outer circumferential surface of the roller shell 10, thereby acting to prevent the roller shell 10 from deviating from the second driving wheel 414 during the driving test.

When the driving test is completed, the guide block 472 is pushed up by the guide block cylinder 474, and the roller shell 10 is pushed upward, wherein the upper surface of the guide block 472 is formed in a horizontal flat shape. When the roller shell 10 is simply lifted up, the roller shell 10 does not enter the traveling direction side guide rail 110 (in the present embodiment, the right guide rail). Accordingly, the guide block 472 is formed to be inclined downward toward an upper surface thereof toward both ends of the guide rail in one longitudinal direction, that is, toward both sides along the driving shaft arrangement direction, and the highest point of the pair The roller is mounted on the driving wheel 410 so as to be positioned behind the roller's conveying direction than the central axis of the roller. In this way, when the peak is located off the central axis of the roller, when the guide block 472 is pushed upwards, the roller shell 10 is rolled on the inclined upper surface of the guide block 472 to Figure 9 As shown in the following will be seated on the traveling side guide rail (110).

On the other hand, in order to be able to automate the operation of each component as described above, the guide block 472 further comprises a sensing means for detecting the presence or absence of the roller is stopped. When the sensing means is provided, the lifting time of the guide block 472 and the lifting time of the driven wheel mounting block 442 can be accurately recognized without inputting a signal by the operator. Lifting, there is an advantage that can be automated the rotation of the drive shaft 420.

In addition, a separate stopper 160 may be further provided below the guide rail 110 to block the supply of the roller shell 10 to the driving wheel 410.

The roller shell 10 shown in (b) and (c) of FIG. 4 has a relatively large diameter as shown in FIG. 10 and is located on the first driving wheel 412 located on the left and right sides of the second driving wheel 414. It is seated and a pair of driven rollers are positioned to spread left and right to contact the upper outer peripheral surface of the roller shell (10). When the driving shaft 420 rotates in the state shown in FIG. 10, the first driving wheel 412 coupled to the driving shaft 420 is rotated and the roller shell seated on the first driving wheel 412. (10) will also rotate.

The roller shell 10 having a small diameter is also caught by the guide block 472 as shown in FIG. 11 when the guide block 472 is raised, and thus cannot be accurately seated between the pair of first driving wheels 412. When the guide block 472 is lowered, it is accurately seated between the pair of first driving wheels 412 as shown in FIG. 12. In addition, when the guide block 472 is raised again in the state shown in FIG. 12, the guide block 472 is seated on the right guide rail 110 on the inclined top surface of the guide block 472. The principle that the roller shell 10 having a small diameter is seated on the first driving wheel 412 and then seated on the guide rail in the traveling direction and the operation of each component are shown in the embodiments shown in FIGS. 6 to 9. Since it is substantially the same as, detailed description thereof will be omitted.

14 is a perspective view showing a position where the fixing means 450 included in the crawler roller test apparatus according to the present invention is in close contact with the roller, and FIG. 15 is a fixation included in the crawler roller test apparatus according to the present invention. 16 and 17 illustrate a process in which the collar 30 is fixed by the fixing means 450 included in the crawler roller testing apparatus according to the present invention.

When the roller shell 10 is rotated, the collar 30 should not be rotated. The protrusion 30 is formed in the collar 30 as shown in FIG. 14, and the fixing means 450 is Interfering with the protrusion 34 serves to restrain the collar 30 from rotating.

That is, the fixing means 450 is a contact block 452 facing the side of the roller seated on the drive wheel 410 coupled to the drive shaft 420, one side is different from each other, the end of the contact block ( Protruding block 454 protruding to one surface of the 452 to block the rotation of the protrusion 34 and the transfer unit for transferring the contact block 452 toward the side of the roller seated on the drive wheel 410 It comprises a fixing means 450 having a (456). At this time, when the protruding block 454 is configured to maintain a protruding state at all times, the end of the protruding portion 34 is an end surface of the protruding block 454 when the contact block 452 is transferred to the collar 30. When in contact with the protruding block 454 does not serve to block the rotation of the protruding portion (34). Therefore, the operator should properly rotate the roller shell 10 so that the protrusion 34 is located at a portion of the one side of the contact block 452 where the protrusion block 454 is not formed. In addition, there is a problem that automation of the driving test becomes impossible.

To solve this problem, as shown in FIG. 15, the protruding block 454 is mounted in the contact block 452 in a structure that can be retracted into the contact block 452. An elastic member 458 is provided therein for applying an elastic force to the protruding block 454 in a direction in which an end of the protruding block 454 protrudes to one surface of the contact block 452. That is, the protruding block 454 maintains the protruding state from one surface of the contact block 452 unless a separate external force is applied, and when the external block is applied in the direction opposite to the protruding direction, the protruding block 454 is drawn into the contact block 452. It is configured to be.

Therefore, when the contact block 452 is transferred to the collar 30 side, as shown in the left figure of FIG. 16, the protrusion 34 is located at a point where the protruding block 454 is not present on one surface of the contact block 452. When the contact is made, even if the collar 30 rotates to some extent as the roller shell 10 rotates, as shown in the right figure of FIG. 16, when the protrusion 34 interferes with the side surface of the protrusion block 454. It can't rotate anymore and it's fixed.

In addition, when the contact block 452 is transferred to the collar 30 side, as shown in the left view of Figure 17, if the protrusion 34 is in contact with the point where the protrusion block 454 is present, the protrusion The block 454 is pushed by the protrusion 34 and drawn into the contact block 452. In this state, the protruding block 454 may not prevent rotation of the protrusion 34, but the collar 30 rotates to some extent in accordance with the rotation of the roller shell 10. As described above, when the position of the protrusion 34 is changed, the protrusion 34 interferes with another protrusion block 454 (the protrusion block 454 located on the lower left side) to prevent rotation. At this time, the protruding block 454 drawn into the contact block 452 by the first protruding portion 34 maintains the protruding state by the elastic force of the elastic member 458.

As such, when the protrusions 34 are configured to be retractable and protruding, the protrusions 34 of the collar 30 cannot be rotated beyond a set angle even when the protrusions 34 of the collar 30 come into contact with each other. And rotation of only the roller shell 10 is possible.

On the other hand, in this embodiment, only one case in which the two protruding block 454 is provided in one contact block 452, the number of the protruding block 454 provided in one contact block 452 is a protrusion ( 34) can be freely changed according to the shape and various conditions.

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment, Comprising: It should be interpreted by the attached Claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
