DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1:

[0032] like Figure 1-8 As shown, a cable assembly end face cutting device includes a cable tray 12, and a cross frame 10 is slidably connected to the top edge of the cable tray 12. Two groups of rollers 11 are rotatably connected to the cross frame 10, and each group of rollers 11 is rollingly connected to the edge of the cable tray 12. Two cross grooves 14 are opened on the cross frame 10, and a slider 15 is slidably connected in each cross groove 14. A group of first electric drive cylinders 17 are fixedly connected to each slider 15, and two mutually symmetrical brackets 16 are fixedly connected to the cylinder bodies of the two groups of first electric drive cylinders 17, and two mutually symmetrical slide rails 18 are fixedly connected to the two brackets 16, respectively. The first clamping plate 21 and the second clamping plate 22 are slidably connected in the two slide rails 18, and the bottom ends of the first clamping plate 21 and the second clamping plate 22 are bent and can be assembled into a semicircle, and an opening 13 that can accommodate the movement of the first clamping plate 21 and the second clamping plate 22 is opened on the cross frame 10.

[0033] Through the above arrangement, the first clamping plate 21 and the second clamping plate 22 can freely move and adjust their positions within the range of the cable tray 12, and can stably and accurately extend into the cable tray 12 to cut the cables, which is convenient for cutting work in the narrow space of the cable tray 12 and easy to operate.

[0034] like Figure 6 , Figure 7 and Figure 8 As shown, a bidirectional lead screw 40 is rotatably connected between the two ends of each slide rail 18, and the thread directions of the two ends of each bidirectional lead screw 40 are opposite. The two ends of each bidirectional lead screw 40 are respectively threadedly connected to the first clamping plate 21 and the second clamping plate 22, and one end of each slide rail 18 is fixedly connected to a first motor 41, and the power output end of each first motor 41 is transmission-connected to one end of the bidirectional lead screw 40. Two symmetrical handles 19 are fixedly connected to the two ends of the two slide rails 18, and a controller 20 is fixedly connected to one of the handles 19. Two mutually symmetrical paddles 27 are respectively fixedly connected to the bottom end surfaces of the first clamping plate 21 and the second clamping plate 22, and each paddle 27 is flush with the bottom end surfaces of the first clamping plate 21 and the second clamping plate 22.

[0035] By providing the handle 19 and the controller 20, the operator can conveniently control the device to perform cutting work, and by providing the paddle 27, the remaining cables can be pushed outward when the first clamping plate 21 and the second clamping plate 22 are opened, so that the operator can accurately select the cutting target, making the cutting work more convenient.

[0036] like Figure 6 , Figure 7 and Figure 8 As shown, a first chain groove 23 is provided in the first clamping plate 21, and a second chain groove 24 is provided in the second clamping plate 22. The bottom ends of the first chain groove 23 and the second chain groove 24 can be joined and connected. Two wheel frames 33 are slidably connected in the first chain groove 23, and a guide wheel 34 is rotatably connected between the two wheel frames 33. A support 42 is fixedly connected to the top of the two slide rails 18, and a vertical groove 48 is provided on the support 42. A wheel axle 39 is movably connected in the vertical groove 48. A tensioning wheel 38 is fixedly connected to the part of the wheel axle 39 located in the support 42, and a wire saw 35 is transmission-connected between the tensioning wheel 38 and the guide wheel 34.

[0037] By setting the guide wheel 34 and the wire saw 35, the wire saw 35 can be operated at high speed to cut the cable, and the wheel frame 33 can slide in the first chain groove 23 and the second chain groove 24, so that the action range of the wire saw 35 covers the cable, thereby achieving complete cutting of the cable. If the guide wheel 34 and the wire saw 35 are between the first clamping plate 21 and the second clamping plate 22, only the cable between the first clamping plate 21 and the second clamping plate 22 will be cut, and the remaining cables will not be affected.

[0038] like Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, a plurality of chain links 28 are slidably connected in the first chain groove 23, and the plurality of chain links 28 are hinged by an axle pin 29 to form a chain. The bottom end of the chain is hinged to the second electric drive cylinder 32, and the top end of the chain is hinged to a connecting terminal 30. Both ends of the axle pin 29 can be slidably connected to the first chain groove 23 and the second chain groove 24. A cylinder frame 31 is fixedly connected to the top of the first clamping plate 21 between the two slide rails 18, and a second electric drive cylinder 32 is fixedly connected to the top of the cylinder frame 31. The output end of the second electric drive cylinder 32 passes through the cylinder frame 31 and is fixedly connected to the connecting terminal 30. A wheel frame 36 is fixedly connected in the middle between the two slide rails 18, and two groups of limiting wheels 37 are symmetrically distributed and rotatably connected in the wheel frame 36, and the wire saw 35 is clamped between each group of limiting wheels 37.

[0039] By providing the chain link 28 and the second electric drive cylinder 32, the second electric drive cylinder 32 can be stably driven to slide in the first chain groove 23 and the second chain groove 24 to achieve the cable cutting action, and by providing the limiting wheel 37, the position of the wire saw 35 can be restricted and guided, effectively preventing the wire saw 35 from always moving in the cutting plane, thereby ensuring the flatness of the cutting surface.

[0040] like Figure 4 , Figure 6 and Figure 7As shown, a sliding seat 43 is slidably connected to one side of the support 42, and a second motor 44 is fixedly connected to the outer side of the sliding seat 43. The power output end of the second motor 44 is transmission-connected to the wheel axle 39. Two sliding rods 46 are fixedly connected to the bottom of the support 42 away from the sliding seat 43. A floating seat 45 is slidably connected to the two sliding rods 46. The floating seat 45 is rotationally connected to one end of the wheel axle 39 extending out of the support 42. Two springs 47 are arranged between the floating seat 45 and the bottom of the support 42, which are respectively surrounded by the outer sides of the two sliding rods 46.

[0041] By setting up the second motor 44, the wire saw 35 can be driven to operate stably, and by setting the wheel axle 39 to move in the vertical groove 48 and cooperating with the elasticity of the spring 47, the wire saw 35 is tensioned, so that the wire saw 35 remains in a tensioned state during the process of moving to cut the cable, thereby improving the cutting stability and further improving the flatness of the cutting surface.

[0042] like Figure 1 , Figure 4 and Figure 5 As shown, an elastic cover cloth 49 is sleeved on the outer side of the first clamp plate 21 and the second clamp plate 22, a fan 51 is fixedly connected to one side of the cross frame 10, a hose 50 passing through the cross frame 10 is connected between the fan 51 and the elastic cover cloth 49, and the hose 50 is connected to the inside of the elastic cover cloth 49 and the fan 51.

[0043] By providing an elastic cover cloth 49, the cutting area can be covered to effectively isolate harmful smoke and dust from leaking out during the cutting process. By providing a hose 50 and a fan 51, harmful smoke and dust can be sucked out and blown away from personnel, effectively protecting the health of the operator.

[0044] like Figure 7 and Figure 8 As shown, two conical pins 25 are arranged on the surface of the bottom end of the first clamping plate 21 facing the second clamping plate 22 , and a conical slot 26 is arranged on the surface of the bottom end of the second clamping plate 22 facing the first clamping plate 21 at the position corresponding to each pin 25 .

[0045] By providing the latch 25 and the slot 26, guidance can be provided when the bottom ends of the first clamp 21 and the second clamp 22 are assembled, ensuring that the first chain slot 23 and the second chain slot 24 can be accurately assembled and docked, thereby ensuring that the second electric drive cylinder 32 and the axle pin 29 can slide smoothly in the first chain slot 23 and the second chain slot 24, and making the first clamp 21 and the second clamp 22 more firmly combined during the cutting process.

[0046] In this embodiment, initially, the operator sets up the device on the cable tray 12, and multiple cables are set up in the cable tray 12 along the linear direction of the cable tray 12, connects the device to the power supply and control system, and connects the upper end of the fan 51 to the exhaust duct, and the far end of the exhaust duct is away from the personnel and the device. At this time, the bottom ends of the first clamping plate 21 and the second clamping plate 22 are in a closed state, the two paddles 27 are in contact with each other, and at this time, the second electric drive cylinder 32 and the chain link 28 are both located in the first chain groove 23.

[0047] Due to the setting of the roller 11, the cross frame 10 and the first clamping plate 21 and the second clamping plate 22 can move freely along the linear direction of the cable tray 12, and by setting the cross groove 14 and the slider 15, the first clamping plate 21 and the second clamping plate 22 can move freely in the linear direction perpendicular to the cable tray 12. The operator holds the handle 19 and manually adjusts the position of the first clamping plate 21 and the second clamping plate 22 to align them with the target cable to be cut and to align them with the position where the target cable needs to be cut.

[0048] Subsequently, the operator manipulates the controller 20 to control the second electric drive cylinder 32 to contract so that the first clamping plate 21 and the second clamping plate 22 descend, and at the same time controls the first motor 41 to drive the bidirectional lead screw 40 to rotate. Since the two ends of the bidirectional lead screw 40 have opposite screw directions, the first clamping plate 21 and the second clamping plate 22 move away from each other and open. During this process, the two paddles 27 move away from each other with the first clamping plate 21 and the second clamping plate 22, and push away the remaining cables around the target cable, so as to facilitate accurate clamping of the target cable.

[0049] After the first clamp plate 21 and the second clamp plate 22 descend so that the target cable enters between the first clamp plate 21 and the second clamp plate 22, the first clamp plate 21 and the second clamp plate 22 stop descending, and the first clamp plate 21 and the second clamp plate 22 are controlled to close again. During the closing process, the latch 25 is inserted into the corresponding slot 26 to guide the bottom ends of the first clamp plate 21 and the second clamp plate 22 to ensure that the first clamp plate 21 and the second clamp plate 22 are firmly combined and the first chain slot 23 and the second chain slot 24 are accurately docked.

[0050] After the first clamp plate 21 and the second clamp plate 22 are closed again, the target cable is confined between the first clamp plate 21 and the second clamp plate 22, and the cable squeezes the elastic cover cloth 49 to wrinkle and deform, so that the elastic cover cloth 49 cooperates with the arc-shaped bottom of the first clamp plate 21 and the second clamp plate 22 to wrap the cable, thereby isolating the harmful smoke generated during the cutting process, and by providing a hose 50 and a fan 51, the harmful smoke can be sucked out and blown to a place away from people, effectively protecting the health of the operator.

[0051] Subsequently, the operator starts the second motor 44, so that the tensioning wheel 38 drives the wire saw 35 to run at high speed, and drives the second electric drive cylinder 32 to extend outward, pushing the chain link 28 and the wheel frame 33 to slide in the first chain groove 23, so that the guide wheel 34 and the wire saw 35 gradually approach the cable to cut the cable. Since the first chain groove 23 is accurately docked with the second chain groove 24, the wheel frame 33 and the chain link 28 can smoothly pass through the first chain groove 23 and enter the second chain groove 24, thereby realizing the cutting of the cable in the second half.

[0052] During the cutting process, the wire saw 35 is restricted by the limiting wheel 37, which effectively prevents the wire saw 35 from shaking, so that the wire saw 35 is always located in the cutting plane, ensuring the flatness of the cable cutting surface, and during the cutting process, the wire saw 35 moves along the trajectory of the wheel frame 33, so that the wheel axle 39 slides up and down in the vertical groove 48, and the elasticity of the sliding rod 46 is used to apply thrust to the wheel axle 39, thereby ensuring that the wire saw 35 always remains in a tensioned state, ensuring the stability of the wire saw 35 during the cutting process.

[0053] After the cable is completely cut, the operator controls the second electric drive cylinder 32 to retract, so that the chain link 28 and the second electric drive cylinder 32 return to the first chain groove 23, controls the first clamping plate 21 and the second clamping plate 22 to reopen, and controls the first clamping plate 21 and the second clamping plate 22 to rise, so that the device is reset and waits for the next cutting work.

[0054] The first electric drive cylinder 17 , the second electric drive cylinder 32 , the wire saw 35 , the first motor 41 , the second motor 44 , etc. are mature existing technologies and will not be described in detail herein.

[0055] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0056] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
