Description

Technical Field

[0001] This disclosure relates to the field of guide bar processing technology, and more specifically, to a guide bar cutting device. Background Technology

[0002] In the production of electronic glass, the glass is transported by a conveyor belt. Guide strips installed on the conveyor belt guide the glass transport. During installation, the guide strips need to be smoothly inserted into the corresponding profiles on the conveyor belt. Due to the long length of the guide strips and the fact that their materials are mostly wear-resistant and soft, dimensional deviations often occur during installation, making it impossible to smoothly insert them into the corresponding profiles. The softness of the guide strip material also makes installation impossible. If forced installation is attempted, jamming or deformation will occur between the guide strip and the profile. The installed guide strip cannot be guaranteed to be straight, affecting the safety of the conveyor belt in transporting the electronic glass.

[0003] When the guide bar is installed in the above-mentioned way, it is usually necessary to use a machine tool to cut the guide bar. During the machine tool processing, due to the characteristics of the guide bar material being relatively soft, too long, easy to deform, and inconvenient to clamp, the machine tool processing is relatively time-consuming. In particular, it is difficult to control the uniformity of the thickness of the guide bar after processing, which will affect the subsequent production and use of the guide bar.

Detailed Implementation

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] In this disclosure, unless otherwise stated, directional terms such as "up" and "down" are used for reference only. Figure 1 In the drawing, "up" and "down" refer to the direction of the component or structure itself, and "inside" and "outside" refer to the inside and outside of the outline of the component or structure itself. "First" and "second" are used to distinguish one element from another and do not have any order or importance. In addition, the same reference numerals in different reference drawings indicate the same element.

[0027] This disclosure provides a guide bar cutting device, with reference to... Figures 1 to 5 As shown, the guide bar cutting device includes a housing 1, a frame assembly 2, and a cutting blade 3. The housing 1 includes a processing channel 101 for the guide bar 4 to pass through. The frame assembly 2 includes a fixing frame 210 and a first adjusting member 220. The fixing frame 210 is detachably connected to the housing 1, and the first adjusting member 220 is positionally adjustable to the fixing frame 210. The cutting blade 3 has a connecting end and a cutting end. The cutting end of the cutting blade 3 extends into the processing channel 101 to cut the guide bar 4 passing through the processing channel 101. The connecting end of the cutting blade 3 is connected to the first adjusting member 220. The first adjusting member 220 is used to adjust the position of the cutting blade 3 relative to the fixing frame 210, thereby indirectly adjusting the position of the cutting end of the cutting blade 3 within the processing channel 101.

[0028] In this way, the cutting tool 3 can process the guide bar 4 that passes through the processing channel 101. During the actual processing of the guide bar 4, the required cutting thickness of various guide bars 4 is also different. The cutting position of the cutting tool 3 can be adjusted by the first adjusting member 220 on the fixing frame 210 connected to the housing 1. This can improve the versatility of the guide bar cutting device for processing guide bars 4 of different sizes, such as different thicknesses.

[0029] It should be noted that the processing channel 101 may include an inlet (not shown in the figure) for inserting the guide bar 4 and an outlet (not shown in the figure) for the guide bar 4 to detach from the guide bar cutting device after processing. When processing the guide bar 4, one end of the guide bar 4 can be inserted into the processing channel 101 from the inlet and then protrude from the outlet. At this time, the operator can adjust the position of the first adjusting member 220 on the fixing frame 210, and then adjust the position of the cutting blade 3 cutting the guide bar 4. The operator can use manpower or other instruments that can pull the guide bar 4 close to the outlet to pull the guide bar 4 out of the outlet. During the process of pulling it out of the outlet, the cutting blade 3 will cut the guide bar 4 inside the processing channel 101. In this way, when the guide bar 4 is completely pulled out of the outlet, the guide bar 4 has been processed by the cutting blade 3, and the processing of one guide bar 4 is completed.

[0030] Furthermore, in the above processing, since the guide bar 4 is first inserted from the inlet and then partially extended from the outlet before the position of the cutting tool 3 is adjusted, after the guide bar 4 is processed, there will be a situation where the end of the guide bar 4 near the outlet is not cut. At this time, the processed end of the guide bar 4 can be inserted into the processing channel 101 again from the inlet and then out from the outlet, and the guide bar 4 near the outlet can be pulled again. In this way, when the guide bar 4 is fully out of the outlet again, the unprocessed part will also be cut by the cutting tool 3, which can improve the processing accuracy of the guide bar cutting device on the guide bar 4.

[0031] During the machining process of the guide bar cutting device, the cutting tool 3 can be replaced as needed under different machining accuracy requirements. Since the fixing frame 210 and the housing 1 are detachably connected, the fixing frame 210 and the housing 1 can be disassembled when replacing the cutting tool 3. In this way, the fixing frame 210 will detach from the housing 1 along with the first adjusting member 220 and the cutting tool 3. At this time, the operator can remove the cutting tool 3 from the first adjusting member 220 and replace the cutting tool 3. After the replacement is completed, the cutting tool 3 can be extended into the machining channel 101 again, and the fixing frame 210 can be connected to the housing 1. Thus, the replacement of the cutting tool 3 is completed.

[0032] In some implementations, reference Figure 1 , Figure 3 and Figure 4 As shown, there are two of each of the support assembly 2 and the two cutting tools 3. The top surface of the housing 1 has two openings 102 for inserting the cutting ends of the two cutting tools 3 into the machining channel 101. The two openings 102 are spaced apart in a direction perpendicular to the extension of the machining channel 101. This arrangement allows one cutting tool 3 to pass through each of the two openings 102. (Refer to...) Figure 1 As shown, the two cutting blades 3 can respectively cut the two sides of the guide bar 4, and the position of the single first adjusting member 220 can be adjusted according to the actual processing needs to change the cutting position of the cutting blade 3 on the guide bar 4, thereby improving the versatility of the guide bar cutting device in processing more guide bars 4 of different shapes in the actual processing process.

[0033] In some implementations, reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the fixing frame 210 includes a first plate 211 and a second plate 212 connected to each other. The second plate 212 is detachably connected to the housing 1. The first plate 211 extends parallel to the top surface of the housing 1. A first threaded hole 213 is provided on the first plate 211. The first adjusting member 220 is a first bolt, which passes through and is threaded into the first threaded hole 213. The end of the first bolt facing the housing 1 is connected to the connecting end of the cutting tool 3. In this way, refer to... Figure 1 As shown, the first plate 211 extends parallel to the top surface of the housing 1, and the first threaded hole 213 penetrates the first plate 211 in a vertical direction. When the first bolt passes through the first threaded hole 213 and connects to the connecting end of the cutting tool 3, the threaded connection between the first bolt and the first threaded hole 213 can improve the stability of the cutting tool 3 during the cutting process of the guide bar 4. The second plate 212 can be detachably connected to the housing 1. When the cutting tool 3 needs to be replaced, the second plate 212 can be separated from the housing 1 to replace the cutting tool 3.

[0034] It should be noted that when the cutting tool 3 is cutting the guide bar 4, the orientation of the cutting tool 3 and the cutting depth need to be adjusted before cutting. This allows the cutting tool 3 to cut the guide bar 4 more safely. When the position of the cutting tool 3 needs to be adjusted, the operator can remove the second plate 212 from the housing 1 and rotate the first bolt to adjust the cutting depth of the cutting tool 3. After adjustment, the second plate 212 can be reconnected to the housing 1, and the cutting tool 3 can then be inserted into the machining channel 101 to complete the adjustment of the cutting depth of the cutting tool 3. Alternatively, the operator can directly rotate the first adjusting member 220 to adjust the cutting depth of the cutting tool 3. In this operation method, the orientation of the cutting tool 3 must also be considered. After the cutting depth is adjusted, the first adjusting member 220 still needs to be rotated for fine adjustment, i.e. Figure 5 As shown, the position adjustment of the cutting tool 3 is completed when the tip of the cutting tool 3 is aligned with the extension direction of the guide bar 4.

[0035] In this disclosure, the connection between the second plate 212 and the housing 1 can be any suitable manner, for example, referring to Figure 1 , Figure 3 and Figure 4 As shown, the second plate 212 may have a small hole penetrating its surface, and the housing 1 may have a screw hole corresponding to the position of the small hole. The second plate 212 and the housing 1 can be connected by threaded fasteners such as screws passing through the small hole on the second plate 212 and screwed into the screw hole on the housing 1 to achieve a detachable connection between the second plate 212 and the housing 1. Alternatively, the hole on the housing 1 may be a blind hole corresponding to the position of the small hole on the second plate 212. A detachable connection between the second plate 212 and the housing 1 can be achieved by a locating pin passing through the small hole on the second plate 212 and connecting to the blind hole on the housing 1. This disclosure does not limit this.

[0036] In some implementations, reference Figure 1 As shown, the housing 1 has an installation space 103 communicating with the opening 102 and the processing channel 101. The cutting end of the cutting tool 3 passes through the opening 102 and the installation space 103 in sequence and extends into the processing channel 101. The guide bar cutting device also includes a first limiting component 5. The first limiting component 5 is detachably connected to the housing 1 and has a limiting end extending into the installation space 103. The limiting end is used to abut against the side of the cutting tool 3, or the limiting end is used to insert into a slot provided on the side of the cutting tool 3. In this way, the first limiting component 5 can further improve the stability of the cutting tool 3 when cutting the guide bar 4. After the fixing frame 210 and the first adjusting member 220 position the height of the cutting tool 3, the limiting end of the first limiting component 5 can control the cutting tool 3 in the following way: Figure 1The transverse direction limit reduces the wobble of the cutting tool 3 when cutting the guide bar 4, thus indirectly improving the service life of the cutting tool 3.

[0037] In some implementations, reference Figure 1 , Figure 3 and Figure 4 As shown, a strip hole 104 communicating with the installation space 103 is provided on the side wall of the housing 1. The extension direction of the strip hole 104 is parallel to the extension direction of the cutting tool 3. The first limiting component 5 passes through the strip hole 104 and is adjustablely connected to the housing 1 along the extension direction of the strip hole 104. The first limiting component 5 includes a limiting screw 510 passing through the strip hole 104 and two limiting nuts 520 threadedly connected to the limiting screw 510. One limiting nut 520 is located inside the installation space 103 and abuts against the inner wall of the installation space 103. The other limiting nut 520 is located outside the housing 1 and abuts against the side wall of the housing 1. The end of the limiting screw 510 located inside the installation space 103 is the limiting end. In this way, when the first limiting component 5 limits the cutting tool 3, a limiting nut 520 away from the limiting end can be pre-screwed onto the limiting screw 510. After the limiting screw 510 passes through the strip hole 104, a limiting nut 520 near the limiting end is screwed into the limiting screw 510. The limiting screw 510 is then rotated again toward the cutting tool 3. When the end face of the limiting screw 510 can abut against the side of the cutting tool 3 or the slot on the side of the cutting tool 3, the limiting nut 520 near the limiting end is rotated until one end face abuts against the inner wall of the housing 1. Then, the other limiting nut 520 is rotated until one end face abuts against the side wall of the housing 1. At this time, the limiting of the cutting tool 3 by the first limiting component 5 can be completed as a whole, allowing the cutting tool 3 to be more stably located in the installation space 103 to cut the guide strip 4.

[0038] In some implementations, reference Figures 1 to 4As shown, the housing 1 includes a guide space 105 communicating with the processing channel 101. The guide space 105 is located above the processing channel 101. The guide bar cutting device also includes a guide mechanism 6. The guide mechanism 6 includes a rolling component 610 and a second adjusting component 620. The rolling component 610 is located in the guide space 105 and is used to roll and adhere to the upper surface of the guide bar 4 passing through the processing channel 101. The second adjusting component 620 is positionally adjustable to the housing 1 and is connected to the rolling component 610 to adjust the movement of the rolling component 610 toward or away from the processing channel 101. In this way, when the guide bar 4 is being cut, the guide mechanism 6 can adjust the position of the rolling component 610 in the guide space 105 according to the different processing shapes of various guide bars 4 through the second adjustment component 620. In this way, when the guide bar 4 is being cut, since the guide bar 4 itself is mostly made of a relatively soft material, it is easy to deform and bend during the processing and is not convenient to clamp. The rolling component 610 can always roll and fit against the upper surface of the guide bar 4 passing through the processing channel 101 to press and guide the guide bar 4, and can also prevent the guide bar 4 from deforming and bending during the processing, thereby improving the cutting efficiency of the guide bar cutting device on the guide bar 4.

[0039] In some implementations, reference Figure 1 and Figure 2 As shown, the second adjustment assembly 620 includes a second limiting member 621, a second bolt 622 and a mounting shaft 623 coaxially connected. A second threaded hole 106 communicating with the guide space 105 is provided on the top surface of the housing 1. The second bolt 622 passes through and is threadedly connected to the second threaded hole 106. The mounting shaft 623 is located in the guide space 105. The rolling assembly 610 is rotatably connected to the mounting shaft 623 about the central axis of the mounting shaft 623. The second limiting member 621 is connected to the mounting shaft 623 to limit the axial movement of the rolling assembly 610 along the mounting shaft 623. In this way, the second bolt 622 and the mounting shaft 623 are arranged in a variable-diameter stepped manner, with the diameter of the mounting shaft 623 being smaller than the diameter of the second bolt 622. Thus, the rolling assembly 610 can be connected to the mounting shaft 623 and fixed by the second limiting member 621. Alternatively, the position of the second bolt 622 on the second threaded hole 106 can be adjusted by rotating the second bolt 622, thereby adjusting the height of the rolling assembly 610. This allows for the clamping and positioning of different types of guide bars 4.

[0040] In other embodiments, the second limiting member 621 can be any suitable one. For example, the second limiting member 621 can be a clamp or a retaining ring. The clamp or retaining ring can be sleeved on the mounting shaft 623 to limit the rolling assembly 610. This disclosure does not limit it in this way.

[0041] In some implementations, reference Figure 1 and Figure 2 As shown, the rolling assembly 610 includes a U-shaped frame 611, a guide shaft 612, and a bearing 613. The U-shaped frame 611 includes two spaced-apart first connecting plates 6111 and a second connecting plate 6112 connected between the two first connecting plates 6111. The second connecting plate 6112 is rotatably connected to the mounting shaft 623 about its central axis. The guide shaft 612 is connected to the two first connecting plates 6111. The bearing 613 is rotatably sleeved on the guide shaft 612 about its own axis, and is located between the two first connecting plates 6111. In this way, the outer wall of the bearing 613 on the guide shaft 612 can press and guide the guide bar 4. During the movement of the guide bar 4 in the processing channel 101, the bearing 613 rolls with the movement of the guide bar 4. Thus, the bearing 613 can both press and guide the guide bar 4 and prevent the guide bar 4 from getting stuck in the processing channel 101, improving the efficiency of the guide bar cutting device in cutting the guide bar 4.

[0042] In some implementations, reference Figure 1 and Figure 2 As shown, two spacers 614 are sleeved on the guide shaft 612, located on opposite sides of the bearing 613. Adjusting screws are provided on the spacers 614, which abut against the guide shaft 612. In this way, after assembling the guide shaft 612 and the bearing 613, spacers 614 can be inserted from both ends of the guide shaft 612. The two spacers 614 can axially position the bearing 613 sandwiched in the middle. During the actual processing of the guide bar 4, the position of the two spacers 614 clamping the bearing 613 can be adjusted according to the shape of different guide bars 4. After determining the positions of the spacers 614 and the bearing 613, the adjusting screws on the spacers 614 can be tightened. Rotating the adjusting screws until their end faces abut against the guide shaft 612 completes the fixation of the spacers 614.

[0043] In some implementations, reference Figure 1 and Figure 2 As shown, a third limiting member 615 is also provided on the guide shaft 612. The third limiting member 615 is used to abut against the U-shaped frame 611 to limit the axial movement of the guide shaft 612. In this way, when the guide bar 4 is processed, the third limiting member 615 can limit the axial direction of the guide shaft 612, which can prevent the guide shaft 612 from moving in the axial direction due to the rotation of the bearing 613, thereby improving the stability of the guide shaft 612 on the U-shaped frame 611.

[0044] It should be noted that the third limiting member 615 can be any suitable structure. For example, the third limiting member 615 can be a clamp connected to the guide shaft 612 and abutting against the U-shaped frame 611, or a threaded section can be provided on the guide shaft 612. The third limiting member 615 is constructed as a nut screwed to the threaded section. One end face of the nut can abut against the U-shaped frame 611 to limit and fix the guide shaft 612. This disclosure does not limit this.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0046] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction.
