Description

Technical Field

[0001] The present invention belongs to the technical field of cutting equipment, and particularly relates to a sleeve cutting jig. Background Art

[0002] Optical devices usually use optical fibers for input and output of optical signals. The packaging module of an optical device is generally small in size, and usually uses bare fibers that are easy to arrange. The diameter of the bare fiber is about 250 μm. However, due to the relatively fragile nature of the bare fiber itself, the bare fiber is usually squeezed and pulled at the fiber outlet of the optical device connection, resulting in easy damage and breakage of the optical fiber. Therefore, a tail sleeve needs to be installed to protect the optical fiber.

[0003] Due to the small size of the optical fiber itself, the size of the tail sleeve itself is also small. Generally, the outer diameter of the tail sleeve sleeved on the optical fiber is about 1.25 mm, and the length of the tail sleeve is 4 mm ± 0.5 mm. Due to the short length of the tail sleeve itself and the thin diameter of the sleeve, the cutting of the tail sleeve is relatively difficult.

[0004] In the prior art, in order to ensure the consistency of tail sleeve cutting, a measuring tool such as a ruler is usually used to measure the length of the sleeve, and then a blade or other cutting tool is used for cutting. However, due to the relatively small size of the sleeve itself, it is easy to cut the finger with the cutting tool during the process of fixing the sleeve by hand, and the consistency of sleeve cutting is not good. The edge of the sleeve cut is prone to skew, and both the cutting quality and cutting efficiency are relatively low. Summary of the Invention

[0028] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0029] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects:

[0030] (1) The casing cutting fixture of the present invention drives the cutting component to swing through the rotating component, so that the cutting part of the cutting component moves towards the cutting table. By placing the casing to be cut at the notch of the accommodating groove, the casing to be cut is cut into a suitable size by the inclined falling of the cutting component. This application completes the mechanized cutting of the casing through the casing cutting fixture, avoiding the problem of cutting the hand during the cutting process, and the rotating component drives the cutting component to fall, so that the cutting part of the cutting component will not shift randomly during the falling process, ensuring the flatness of the cutting end of the casing.

[0031] (2) The casing cutting fixture of the present invention sets the first carrier table and the second carrier table in an openable and closable form, and a material box is arranged below the cutting table. After the cutting component finishes cutting the casing, by separating the first carrier table and the second carrier table along the first direction, the casing cut at the notch of the accommodating groove can fall into the material box, completing the automatic collection after the casing cutting is completed.

[0032] (3) The casing cutting fixture of the present invention sets a plurality of first carrier plates, and drives the first carrier plates to move along the third direction by using the distance-adjusting screws, so that the cutting gap position between adjacent first carrier plates is adjustable. By cooperating with the positions of seven components, the cutting length of the casing can be changed to meet the cutting requirements of different casing lengths.

[0033] (4) The casing cutting fixture of the present invention sets a first positioning pin, and drives the first carrier plate to move towards or away from the second carrier plate by using the first positioning pin, so as to adjust the distance of the notch of the accommodating groove between the first carrier plate and the second carrier plate along the second direction, for accurately locking the position of the casing, facilitating the cutting component to accurately cut the casing, and realizing the precise control of the cutting length of the casing.

[0034] (5) The casing cutting fixture of the present invention fixes the second carrier plate through the carrier plate and the pressing plate, and uses the tightening screw to abut against the pushing plate to drive the second carrier plate to move towards the first carrier plate to form a notch of the accommodating groove, facilitating the placement of the casing; when it is necessary to put the cut casing into the material box, by loosening the tightening screw, the first spring drives the rebounding screw to move away from the first carrier plate, and then the rebounding screw drives the second carrier plate to move in the direction away from the first carrier plate, so that the first carrier plate and the second carrier plate are separated, facilitating the cut casing at the notch of the accommodating groove to fall into the material box, completing the collection of the casing.

[0046] Example:

[0047] See also Figures 1 to 3 The casing cutting jig in the preferred embodiment of the present invention includes a cutting table 1, which includes a first stage and a second stage arranged along a first direction, and a receiving slot 4 is formed at the junction of the first stage and the second stage in the first direction, and the first stage and the second stage are opened and closed along the first direction; a rotating component 5, one end of the rotating component 5 is hinged to the cutting table 1, and the other end thereof extends along the second direction; a cutting component 6, the cutting portion of the cutting component 6 is arranged toward the cutting table 1, and the cutting component 6 is connected to the end of the rotating component 5 away from the cutting table 1; correspondingly, the casing cutting jig also includes a material box 7, which is arranged on a side of the cutting table 1 away from the cutting component 6, and the material box 7 at least covers the receiving slots 4 of the first stage and the second stage along the first direction.

[0048] It is worth noting that the first direction in the present application is the direction in which the first stage and the second stage are arranged side by side, the second direction is the vertical direction, that is, the direction in which the cutting part of the cutting assembly 6 moves vertically, and the third direction is the direction in which the accommodating slot 4 is opened, that is, the placement direction of the sleeve to be cut.

[0049] The casing cutting jig in this application forms a receiving notch 4 through the first carrier table and the second carrier table. The casing to be cut is placed at the receiving notch 4, and then the cutting assembly 6 is driven by the rotating assembly 5 to move towards the receiving notch 4. The cutting part of the cutting assembly 6 cuts the casing placed at the receiving notch 4, completing the automatic cutting process of the casing. At the same time, after the casing is cut, the first carrier table and the second carrier table are separated along the first direction, so that the cut casing falls into the material box 7, completing the automatic cutting and collection process of the casing, greatly improving the cutting and storage efficiency of the casing.

[0050] Further, the rotating assembly 5 in this application includes a connecting plate 502 and a first connecting rod 501. The first connecting rods 501 are arranged in pairs, and one end of each of the two first connecting rods 501 is connected to the cutting table 1, and the other ends are both connected to the connecting plate 502. The connecting plate 502 is connected to the cutting assembly 6. The rotating assembly 5 in this application is a link mechanism. One end of the first connecting rod 501 is connected to the cutting table 1, and the other end is connected to the connecting plate 502. And the cutting assembly 6 is arranged on the connecting plate 502. The cutting assembly 6 is driven to rotate by the first connecting rod 501, so that the cutting assembly 6 moves downward and towards the receiving notch 4, and the cutting of the casing is completed through the movement of the connecting rod. Specifically, the first connecting rods 501 are arranged in pairs, and the two first connecting rods 501 are arranged on both sides of the first carrier table along the third direction. The two first connecting rods 501 form a supporting structure for the connecting plate 502, so that the cutting assembly 6 is stably connected to the connecting plate 502, facilitating the stable cutting of the casing by the cutting assembly 6. It should be noted that this application needs to adapt and adjust the setting position of the first connecting rod 501 so that when the first connecting rod 501 drives the cutting assembly 6 to swing, the cutting part of the cutting assembly 6 just drops to the receiving notch 4 to cut the casing placed at the receiving notch 4.

[0051] Further preferably, the rotating assembly 5 in this application further includes a second connecting rod 503. The second connecting rods 503 are arranged in pairs, and one end of each of the two second connecting rods 503 is connected to the above-mentioned cutting table 1, and the other ends are both connected to the connecting plate 502, and the first connecting rod 501 and the second connecting rod 503 are arranged in parallel. Since the first connecting rod 501 and the connecting plate 502 are in point contact, the two first connecting rods 501 cannot ensure the stability of the connecting plate 502, causing the cutting assembly 6 to shake on the connecting plate 502 and reducing the cutting accuracy. This application correspondingly sets the second connecting rod. Through the two first connecting rods and the two second connecting rods, a four-point support structure is formed, so that the swinging amplitude of the connecting plate 502 is consistent with that of the connecting rod, realizing the precise control of the movement of the cutting assembly 6 on the connecting plate 502.

[0052] Further preferably, the casing cutting jig in the present application further includes a second spring 504. One end of the second spring 504 is connected to the cutting table 1, and the other end is connected to the first connecting rod. Moreover, the end of the second spring 504 connected to the cutting table 1 is provided at one end of the first loading platform away from the accommodation notch 4. Since the cutting assembly 6 will move towards the accommodation notch 4 during the movement of the rotating assembly 5, and the movement directions of the cutting assembly 6 are the first direction and the second direction. In order to enable the cutting assembly 6 to return to its original position after the casing is cut, facilitating the next cutting, the present application provides the second spring 504, and the second spring 504 has a telescopic amount along the first direction. After the cutting assembly 6 cuts the casing, the second spring 504 has a restoring force to pull the cutting assembly 6 back to its original position, facilitating the next cutting.

[0053] Further, as a preferred embodiment of the present invention, the cutting assembly 6 in the present application includes two pairs of clamping plates arranged in pairs. An installation hole is formed between the two clamping plates and opened along the second direction. A blade is installed at the installation hole, and the blade is used for cutting the casing. On the side of the two clamping plates away from the blade, installation screws are connected. Installation holes are opened along the third direction on the connecting plate 502. The above installation screws are correspondingly inserted into the installation holes. By screwing the installation screws, the installation fastening degree between the clamping plates and the connecting plate 502 can be realized, and further the position adjustment of the blade in the installation hole can be completed to complete the cutting of casings of different lengths.

[0054] Optionally, there can be multiple cutting assemblies 6 in the present application. The multiple cutting assemblies 6 are fixedly arranged at intervals along the third direction in the installation hole. Through the connecting plate 502, multiple cutting assemblies 6 can be controlled to move simultaneously, realizing the simultaneous cutting of multiple casings at one time.

[0055] Further, a casing passing hole 17 is opened on one side of the cutting table 1 in the third direction. The casing passing hole 17 is arranged opposite to the accommodation notch 4 along the third direction. It is used to place the casing passing through the casing passing hole 17 at the accommodation notch 4 along the third direction, facilitating cutting.

[0056] Correspondingly, a cutting baffle 18 is provided on the side of the accommodation notch 4 away from the casing passing hole 17. The cutting baffle 18 at least partially coincides with the casing passing hole 17 along the third direction. The cutting baffle 18 is mainly used to block the casing passing through the casing passing hole 17, that is, to limit the initial position of the casing. When the casing abuts against the side wall of the cutting baffle 18, the initial end of the casing is confirmed. Only by adjusting the position between the cutting assembly 6 and the side wall of the cutting baffle 18 can the control of the cutting length of the casing be realized.

[0057] Furthermore, as a preferred embodiment of the present invention, the first stage in the present application includes a plurality of first carrier plates 112 arranged in parallel along a third direction, and a gap is left between each two adjacent first carrier plates 112 for the cutting part to pass through; the cutting table 1 is also provided with a distance adjusting screw 8 along the third direction, the distance adjusting screw 8 is adjustable along the third direction, and the distance adjusting screw 8 is connected to the plurality of first carrier plates 112. Since a receiving slot 4 is formed at the first stage and the second stage, the cutting part of the cutting assembly 6 needs to fall into the receiving slot 4 to cut off the sleeve, so the cutting assembly 6 may interfere with the first stage during the falling process. The present application corresponds to setting the first stage in the form of a plurality of first carrier plates 112, and reserving a cutting gap between adjacent first carrier plates 112 to facilitate the blade to fall into the gap. At the same time, when the cutting assembly 6 moves toward the receiving slot 4, the gap between the adjacent first carrier plates 112 can guide the movement of the blade to limit the cutting direction of the blade, ensure the accuracy of the sleeve cutting position, and avoid the problem of uneven cutting of the sleeve end. At the same time, the present application sets a distance adjustment screw 8 along the third direction, and drives the above-mentioned first carrier plate 112 to move along the third direction through the distance adjustment screw 8, and correspondingly adjusts the position of the cutting assembly 6 in the third direction, so that the cutting position of the sleeve by the cutting assembly 6 can be adjusted at any time to cut sleeves of different lengths.

[0058] It is worth noting that the multiple first carrier plates 112 in the present application are embedded in the carrier table. According to actual needs, first carrier plates 112 with different thicknesses in the third direction can be selected, and the number of first carrier plates 112 can be increased or decreased according to needs, so that the cutting gap between adjacent first carrier plates 112 is adjustable along the third direction.

[0059] Furthermore, the first positioning pins 9 are provided on the side of the first carrier plates 112 in the present application away from the accommodating slot 4 along the first direction, and each first positioning pin 9 connects each first carrier plate 112 to the cutting table 1. The side of the first carrier plate 112 facing the accommodating slot 4 is connected by the distance adjusting screw 8, but the end away from the accommodating slot 4 is in an active state. The present application sets the first positioning pin 9 and uses the first positioning pin 9 to fix the first carrier plate 112, so as to ensure that the gap between adjacent first carrier plates 112 remains stable during cutting. Correspondingly, the cutting table 1 in the present application has a gap extending along the third direction at the joint between the first positioning pin 9, so that the first positioning pin 9 can be displaced along the third direction after connecting the first carrier plate 112; correspondingly, there is also a gap between the distance adjusting screw 8 and the mounting hole of the cutting table 1 along the first direction, so that the distance adjusting screw 8 can drive the first carrier plate 112 to move as a whole along the first direction. Of course, the displacement range of the first positioning pin 9 and the distance adjusting screw 8 is relatively small, which will not cause the first loading plate 112 to loosen as a whole.

[0060] Preferably, the gap between adjacent first carrier plates 112 in the present application is in the form of being wider at the top and narrower at the bottom. On the one hand, it can guide the cutting assembly 6, and on the other hand, it can accommodate the cutting part of the cutting assembly 6 to prevent the cutting part from being exposed and injuring the operator.

[0061] Furthermore, as a preferred embodiment of the present invention, the second carrier table in the present application includes a plurality of second carrier plates 113 arranged side by side in the third direction. There is a gap for the cutting part to pass through between two adjacent second carrier plates 113. The gap between the second carrier plates 113 corresponds to the gap between the first carrier plates 112, so that the cutting part can correspondingly pass through the accommodation notch 4 to cut off the sleeve to be cut. At the same time, carrier plates 11 and pressing plates 10 are respectively arranged at both ends of the plurality of second carrier plates 113 in the second direction. The pressing plate 10 and the carrier plate 11 are connected along the second direction by knob screws 12. By arranging the pressing plate 10 and the carrier plate 11 on the upper and lower sides of the second carrier plates 113 respectively and cooperating with the knob screws 12 to fix the second carrier plates 113, the gap between the second carrier plates 113 is kept aligned with the gap on the first carrier plates 112. Similarly, when the second carrier plates 113 are displaced, increased, decreased or replaced in the third direction, the second carrier plates 113 can be fixed again by the knob screws 12 to complete the adjustment of the position of the second carrier plates 113.

[0062] Furthermore, a pushing plate 13 is arranged on the side of the second carrier plate 113 facing away from the first carrier plate 112. The pushing plate 13 is connected to the pressing plate 10. A tightening screw 15 is inserted through the cutting table 1 in the first direction. The tightening screw 15 is threadedly connected to the cutting table 1, and the side wall of the pushing plate 13 is abutted against the side of the tightening screw 15 facing the pushing plate 13. The adjustment range of the first carrier plate 112 driven by the first positioning pin 9 in the first direction is relatively small, mainly for ensuring the docking accuracy between the first carrier plate 112 and the second carrier plate 113. The opening and closing of the accommodation notch 4 between the first carrier plate 112 and the second carrier plate 113 are mainly realized by adjusting the second carrier plate 113. In the present application, by arranging the tightening screw 15, the rotation of the tightening screw 15 is used to push the pushing plate 13 to move, thereby realizing the movement of the second carrier plate 113 towards or away from the first carrier plate 112.

[0063] Preferably, a plurality of second positioning pins 14 are arranged on the side of the second carrier plate 113 facing away from the first carrier plate 112. The number of the second positioning pins 14 is the same as the number of the second carrier plates 113. The second positioning pins 14 are threadedly connected to the pushing plate 13 and extend into the second carrier plates 113 for precisely adjusting the positions of the second carrier plates 113 in the first direction. Optionally, the second positioning pins 14 are threadedly connected to the carrier plate 11, and they can also drive the second carrier plates 113 to move in the first direction.

[0064] Further, a return spring screw 16 is provided on the cutting table 1 along the first direction. The return spring screw 16 passes through the cutting table 1 along the first direction and is connected to the pushing plate 13. A first spring is sleeved on the return spring screw 16. One end of the first spring abuts against the side wall of the cutting table 1, and the other end abuts against the end of the return spring screw 16 away from the pushing plate 13. In order to realize the automation of the return movement of the second carrier plate 113, the return spring screw 16 is correspondingly arranged in this application. When the tightening screw 15 drives the pushing plate 13 to move towards the first carrier plate 112, the end of the return spring screw 16 connected to the pushing part is correspondingly displaced, and the first spring is compressed. When the tightening screw 15 is rotated in the reverse direction, the pushing plate 13 loses the support of the tightening screw 15, the first spring rebounds, the return spring screw 16 drives the pushing plate 13 to move away from the first carrier plate 112, the first carrier plate 112 and the second carrier plate 113 are separated along the first direction, and an opening is generated at their joint. The cut sleeve falls into the lower material box 7 from the opening, completing the automatic collection of the sleeve.

[0065] Further, the cutting table 1 in this application constitutes a square frame structure. The above-mentioned first positioning pin 9, return spring screw 16, first connecting rod 501, second connecting rod 503, etc. are all connected to the surrounding frame of the cutting table 1. And the opposite surfaces of the first carrier plate 112 and the second carrier plate 113 in this application are inclined to each other along the first direction, and they form a V-shaped accommodating notch 4.

[0066] The working process of the sleeve cutting jig in the present invention is as follows:

[0067] Turn the tightening screw 15. The tightening screw 15 abuts against the pushing plate 13. The pushing plate 13 pushes the second carrier plate 113 to move towards the first carrier plate 112. The first carrier plate 112 and the second carrier plate 113 form an accommodating notch 4. Pass the sleeve to be cut through the sleeve through hole 17. Place the sleeve at the accommodating notch 4 and abut the end of the sleeve against the cutting baffle 18; press down the connecting plate 502 so that the connecting plate 502 moves towards the side of the accommodating notch 4. The first connecting rod 501 and the second connecting rod 503 rotate, and the blade of the cutting assembly 6 moves downward and towards the sleeve to be cut. The blade enters the gap between the adjacent first carrier plates 112. The blade completes the cutting of the sleeve. Release the pressure on the connecting plate 502. The second spring 504 contracts and pulls the connecting plate 502 back. The blade disengages from the accommodating notch 4 and moves away from the cut sleeve; rotate the tightening screw 15 in the reverse direction. The first spring rebounds and drives the return spring screw 16 to move away from the accommodating notch 4. The return spring screw 16 drives the second carrier plate 113 to move away from the first carrier plate 112.
