[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0045] See also Figure 1 to Figure 11 In an embodiment of the present invention, a continuous unequal diameter double-head hole grinding device for a ferrule connector includes: a truss 1, a control box 2, a support rod 3, an inner diameter clamping assembly, a card plate 7, a pushing and rotating mechanism, a hole grinding mechanism, a transmission rod 22, a hole grinding disk 2201, a trigger transmission assembly, and a speed control mechanism. In order to ensure that the ferrule connectors with different apertures can be ground, it is necessary to adjust the positions of the card plate 7 and the hole grinding disk 2201 to ensure that the hole grinding effect is optimal. Therefore, when the ferrule connector is sleeved on the card plate 7, under the action of the pushing and rotating mechanism, the card plate 7 is driven by the clamping assembly to move in directions away from each other. At the same time, the pushing and rotating mechanism will also drive the hole grinding mechanism to move, and control the hole grinding disk 2201 to move toward the ferrule connector through the transmission rod 22. When the hole grinding disk 2201 moves to the position of abutting the inner wall, the hole grinding mechanism provides a certain thrust to the hole grinding disk 2201 to ensure the effect of grinding the ferrule connector. When the card plate 7 is tightly fitted with the ferrule connector, the pushing and rotating mechanism will also drive the trigger transmission component to move, and when the trigger transmission component can drive the speed control mechanism to move, the pushing and rotating mechanism will drive the ferrule connector to rotate through the inner diameter clamping component and the card plate 7. At the same time, the speed control mechanism will drive the hole grinding disk 2201 to rotate through the transmission rod 22 to perform a comprehensive hole grinding process on the ferrule connector. Among them, the speed control mechanism can also automatically adjust the speed of the hole grinding disk 2201 according to the size of the ferrule connector to ensure the best grinding effect.

[0046] The details are as follows, including:

[0047] A truss 1, and a control box 2 mounted on the truss 1, wherein a support rod 3 is rotatably mounted on the control box 2;

[0048] Also includes:

[0049] See also Figure 1 , Figure 2 , Figure 4 , Figure 5, an inner diameter clamping assembly is arranged on the support rod 3, and a clamping plate 7 is connected to the inner diameter clamping assembly. The inner diameter clamping assembly includes a fixed sleeve 4 installed on the support rod 3, and a sliding sleeve 8 is slidably installed on the support rod 3. The fixed sleeve 4 and the sliding sleeve 8 are respectively hinged with a first hinged rod 5 and a second hinged rod 6 hinged to each other, and the second hinged rod 6 is hinged to the clamping plate 7; it also includes a groove 701 opened on the clamping plate 7, and a movable block 702 is slidably installed in the groove 701, and the movable block 702 is hinged to the first hinged rod 5.

[0050] In detail, when the ferrule connector is subjected to hole grinding, the ferrule connector needs to be fixed. In the initial state, the sliding sleeve 8 is located at the end of the stroke away from the fixed sleeve 4, so that the angle between the first hinge rod 5 and the second hinge rod 6 is minimized, so that the spacing between the clamping plates 7 is minimized. When the ferrule connector needs to be ground, the ferrule connector can be sleeved between the clamping plates 7. At this time, under the action of the pushing and rotating mechanism, the sliding sleeve 8 is driven to move toward the fixed sleeve 4, thereby driving the second hinge rod 6 and the first hinge rod 5 to move. The first hinge rod 5 will also drive the movable block 702 to move along the length direction of the groove 701, so that the clamping plates 7 move in the direction away from each other. When the clamping plates 7 move to abut against the inner wall of the ferrule connector, the ferrule connector is fixed.

[0051] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8 The control box 2 is provided with a pushing and rotating mechanism connected to the inner diameter clamping assembly, and the pushing and rotating mechanism can drive the card plate 7 to move toward or away from each other through the inner diameter clamping assembly, and drive the card plate 7 to rotate around the support rod 3. The pushing and rotating mechanism includes a screw rod 10 rotatably mounted on the control box 2, and a threaded sleeve 11 that is threadedly matched with the screw rod 10 is movably mounted on the screw rod 10. The control box 2 is provided with a guide rod 13, and a guide sleeve 14 is slidably mounted on the guide rod 13. A guide sleeve 14 is provided between the guide sleeve 14 and the threaded sleeve 11. A connecting plate 12, wherein the connecting plate 12 is provided with a guiding assembly connected to the sliding sleeve 8, wherein the guiding assembly includes a rotating sleeve 9 slidably mounted on the support rod 3 and rotatably connected to the sliding sleeve 8, the connecting plate 12 is provided with guide columns 16 which are symmetrically arranged and slidably connected to the rotating sleeve 9, the support rod 3 is sleeved with a No. 1 spring 15 which abuts against the rotating sleeve 9; it also includes a straight groove 301 and a spiral groove 302 opened on the support rod 3, and the connecting plate 12 is provided with a limit block 1201 which is slidably connected to the straight groove 301 and the spiral groove 302.

[0052] It should be noted that when the ferrule connector is ground, it is necessary to fix the ferrule connector, and after fixing, it is also necessary to control the rotation of the ferrule connector to ensure that the ferrule connector is fully ground. In the initial state, the threaded sleeve 11 is located at the end of the stroke toward the control box 2, so that the connecting plate 12 is also located at the end of the stroke toward the control box 2, and the limit block 1201 is located at the end of the stroke on the side of the straight groove 301 away from the spiral groove 302. The No. 1 spring 15 is in a compressed state, so that the rotating sleeve 9 is located away from the connecting plate 1 2, and under the action of the guide column 16, after ensuring that the spacing between the rotating sleeve 9 and the connecting plate 12 reaches the maximum, the guide column 16 can drive the rotating sleeve 9 to move. Under the action of the rotating sleeve 9, the sliding sleeve 8 is located at the end of the stroke in the direction away from the fixed sleeve 4, and the spacing between the card plates 7 is the smallest. When the card sleeve connector needs to be fixed, at this time, the screw rod 10 rotates, driving the threaded sleeve 11 to move, thereby driving the guide sleeve 14 to move along the length direction of the guide rod 13 through the connecting plate 12, and the guide The rod 13 and the guide sleeve 14 have a guiding function, ensuring that the threaded sleeve 11 moves along the length direction of the screw rod 10 and does not rotate with the screw rod 10. The connecting plate 12 will also drive the rotating sleeve 9 to move along the length direction of the support rod 3 through the No. 1 spring 15, thereby driving the sliding sleeve 8 to move toward the fixed sleeve 4, so that the spacing between the card plates 7 is maximized. At the same time, the connecting plate 12 will also drive the limit block 1201 to move along the length direction of the straight groove 301. When the card plate 7 abuts against the inner wall of the card sleeve connector, the limit block 12 01 is still in the straight groove 301, the connecting plate 12 continues to move and continues to compress the No. 1 spring 15, so that the supporting force of the card plate 7 on the card sleeve connector increases, and when the limit block 1201 moves to the connection position between the straight groove 301 and the spiral groove 302, the limit block 1201 will slide along the trajectory of the spiral groove 302, so that the support rod 3 rotates, thereby driving the first hinge rod 5 to move through the fixed sleeve 4, so as to drive the card sleeve connector to rotate around the support rod 3 through the card plate 7, so as to ensure that the card sleeve connector is fully ground.

[0053] See also Figure 1 , Figure 2 , Figure 6 , Figure 7The hole grinding mechanism is arranged on the truss 1 and connected with the pushing and rotating mechanism. The hole grinding mechanism is connected with a transmission rod 22, and a hole grinding disc 2201 is arranged on the transmission rod 22. When the pushing and rotating mechanism moves, the hole grinding mechanism can drive the hole grinding disc 2201 to move in the vertical direction through the transmission rod 22. The hole grinding mechanism includes a support sleeve 18 installed on the truss 1, and a movable rod 19 is slidably installed in the support sleeve 18. The end of the movable rod 19 is provided with a movable plate 21, and the movable plate 21 is rotatably connected to the transmission rod 22. The support sleeve 18 is provided with a follower assembly connected with the rotating sleeve 9, wherein the follower assembly includes a slot 1801 opened on the support sleeve 18, and the movable rod 19 is provided with a fixed block 1901 slidably connected with the slot 1801, and a sliding plate 23 abutting against the fixed block 1901 is slidably installed on the support sleeve 18, and a No. 2 spring 20 abutting against the sliding plate 23 is sleeved on the support sleeve 18 and the movable rod 19; and it also includes a connecting rod 24 hinged on the rotating sleeve 9 and hinged with the sliding plate 23.

[0054] Furthermore, the grinding disk 2201 is used to grind the inner wall of the ferrule connector. In the initial state, the rotating sleeve 9 is located at the end of the stroke toward the control box 2. Under the action of the connecting rod 24, the sliding plate 23 is located at the end of the stroke toward the truss 1. Since the sliding plate 23 is in contact with the fixed block 1901, the fixed block 1901 is located at the end of the stroke on one side of the slot 1801. The No. 2 spring 20 is in a compressed state. When the ferrule connector needs to be ground, at this time, under the action of the screw rod 10, the rotating sleeve 9 moves in the direction away from the control box 2, and drives the sliding plate 23 to move through the connecting rod 24. The sliding plate 23 will control the movable plate 21 to move synchronously through the No. 2 spring 20, so that the movable rod 1 9 moves along the length direction of the supporting sleeve 18 to ensure that the fixed block 1901 is always in contact with the sliding plate 23. The movable plate 21 will also move through the transmission rod 22 to control the grinding disk 2201 to move toward the inner wall of the ferrule connector. When the grinding disk 2201 moves to the position in contact with the inner wall, the clamping plate 7 has not yet fitted with the inner wall. Therefore, the rotating sleeve 9 continues to move and controls the movement of the sliding plate 23. Since the position of the grinding disk 2201 no longer changes, the sliding plate 23 will compress the No. 2 spring 20, thereby increasing the pressure applied by the grinding disk 2201 on the inner wall of the ferrule connector, thereby increasing the friction and making the grinding effect better. When the clamping plate 7 moves to the position in contact with the inner wall, the position of the sliding plate 23 no longer changes.

[0055] See also Figure 1-Figure 3 , Figure 5 , Fig. 9 , Fig.10, a trigger transmission assembly is arranged on the control box 2 and connected to the pushing and rotating mechanism. The trigger transmission assembly includes a hollow rod 26 rotatably installed on the control box 2, and a limit tooth 27 is slidably installed on the hollow rod 26. A rotating rod 29 is rotatably installed on the control box 2, and a follower tooth 30 cooperating with the limit tooth 27 is provided on the rotating rod 29. A limit plate 17 abutting against the limit tooth 27 is provided on the connecting plate 12; it also includes a No. 3 spring 28 sleeved on the hollow rod 26 and abutting against the limit tooth 27, and a first belt 25 rotatably connected to the hollow rod 26 is sleeved on the screw rod 10.

[0056] Furthermore, in order to ensure that the hole grinding disk 2201 will not start to rotate until it contacts the inner wall, it is necessary to control the cooperation state of the follower tooth 30 and the limit tooth 27. In the initial state, the sub-connecting plate 12 is located at the end of the stroke toward the control box 2. Under the action of the limit plate 17, the distance between the limit tooth 27 and the follower tooth 30 is maximized, so that the No. 3 spring 28 is in a compressed state. When the screw rod 10 rotates, the control card plate 7 and the hole grinding disk 2201 move. At the same time, the screw rod 10 will also drive the hollow rod 26 to rotate through the first belt 25. Since a limit rod is provided on the hollow rod 26 and a limit groove is provided on the limit tooth 27, the limit tooth 27 rotates synchronously. The screw rod 10 will also control the connecting plate 12 to move away from the control box 2, so that the limit plate 17 moves synchronously. The No. 3 spring 28 The elastic release makes the limit tooth 27 always fit with the limit plate 17 and move toward the follower tooth 30. When the limit block 1201 moves to the connection position of the straight groove 301 and the spiral groove 302, the limit tooth 27 just moves to the matching position with the follower tooth 30, and the connecting plate 12 continues to move, so that the limit tooth 27 enters the spiral groove 302, so that the support rod 3 rotates, and the card plate 7 controls the rotation of the card sleeve connector. At the same time, the connecting plate 12 drives the limit plate 17 to separate from the limit tooth 27, and the limit tooth 27 will drive the follower tooth 30 to rotate synchronously, thereby driving the rotating rod 29 to rotate, so as to drive the transmission rod 22 to rotate through the speed control mechanism, so that the grinding disk 2201 itself rotates, so as to realize the control of the rotation of the card sleeve connector while the grinding disk 2201 rotates, thereby performing a comprehensive hole grinding process on the card sleeve connector.

[0057] See also Figure 1 , Figure 2 , Figure 5 , Fig. 9 , Fig.11The control box 2 is provided with a speed control mechanism connected with the trigger transmission assembly and the transmission rod 22, and the pushing and rotating mechanism can drive the speed control mechanism to move through the trigger transmission assembly to drive the transmission rod 22 to rotate, and the speed control mechanism includes a turntable 34 installed at the end of the rotating rod 29 away from the control box 2, and the turntable 34 is provided with a plurality of slide grooves 3401 distributed equidistantly around the circumference, and a sliding rod 35 is slidably installed in the slide groove 3401, and an arc plate 36 is provided at the end of the sliding rod 35, and a second belt 37 rotatably connected to the transmission rod 22 is sleeved on the arc plate 36, and an elastic component connected to the sliding rod 35 is provided on the rotating rod 29, wherein the elastic component includes a movable sleeve 32 slidably installed on the rotating rod 29, and a push rod 33 hinged to the sliding rod 35 is hinged on the movable sleeve 32, and a No. 4 spring 31 abutting against the movable sleeve 32 is sleeved on the rotating rod 29.

[0058] To elaborate, in the initial state, since the rotating sleeve 9 is located at the end of the stroke toward the control box 2, under the action of the connecting rod 24 and the sliding plate 23, the transmission rod 22 and the grinding disk 2201 are located at the end of the stroke toward the truss 1. Therefore, the distance between the transmission rod 22 and the turntable 34 is the largest. Under the action of the second belt 37, the distance between the arc plates 36 is the smallest. The sliding rod 35 is located at the end of the stroke in the slide groove 3401. Under the action of the push rod 33, the movable sleeve 32 is located at the end of the stroke away from the turntable 34, so that the No. 4 spring 31 is in a compressed state. When it is necessary to grind the hole of the ferrule connector, the strength of the hole grinding required for the ferrule connector is related to the size of the ferrule connector. If the size of the ferrule connector is larger, the required grinding strength is greater. Conversely, the grinding strength is smaller. Therefore, when the screw rod 10 rotates, the transmission rod 22 and the grinding disk 2201 will move toward the inner wall of the ferrule connector, and the distance between the transmission rod 22 and the turntable 34 is The fourth spring 31 is elastically released, and the movable sleeve 32 is controlled to move toward the direction of the turntable 34. Under the action of the push rod 33, the sliding rod 35 moves in the direction away from the slide groove 3401, so that the spacing between the arc plates 36 increases, ensuring that the second belt 37 is always in a taut state. At this time, the transmission ratio between the arc plates 36 and the transmission rod 22 will change. When the grinding disk 2201 moves to the position abutting the inner wall of the ferrule connector, the position of the transmission rod 22 no longer changes, thereby achieving the effect of adaptively adjusting the rotation speed of the grinding disk 2201 according to the inner diameter of the ferrule connector. At this time, under the action of the limit tooth 27 and the follower tooth 30, the rotating rod 29 is rotated to control the rotation of the turntable 34, thereby driving the arc plate 36 to move through the sliding rod 35, so as to drive the transmission rod 22 to rotate through the second belt 37, and the transmission rod 22 will drive the grinding disk 2201 to rotate to grind the ferrule connector.

[0059] A method for grinding holes of a continuous unequal diameter double-end hole grinding device for a ferrule connector comprises the following steps:

[0060] Step 1: Place the ferrule connector with the required hole grinding between the clamping plates 7, and under the action of the pushing and rotating mechanism, drive the clamping plates 7 to move away from each other through the inner diameter clamping assembly until the clamping plates 7 abut against the inner wall of the ferrule connector;

[0061] Step 2: Pushing the rotating mechanism will also drive the grinding mechanism to move, and the grinding disc 2201 is controlled by the transmission rod 22 to move to a position abutting against the inner wall of the ferrule connector;

[0062] Step 3: Push the rotating mechanism to continue to move, and control the rotation of the ferrule connector through the inner diameter clamping assembly and the clamping plate 7. Push the rotating mechanism to control the movement of the speed control mechanism by triggering the transmission assembly, so as to drive the grinding disk 2201 to rotate through the transmission rod 22. Under the action of the grinding disk 2201, the inner wall of the ferrule connector is ground;

[0063] Step 4: If the inner diameter of the ferrule connector is large, the speed control mechanism moves under the action of the transmission rod 22 to control the speed of the grinding disk 2201 to increase through the transmission rod 22, thereby increasing the grinding effect.
