[0026] Embodiment 1

[0029] A pressing groove 10 is provided on the upper surface of the base 1, and the pressing groove 10 is located directly below the pressing block 3 and cooperates with the pressing block 3. A connecting rod 11 is fixedly connected to the upper surface of the pressing block 3, and the upper end surface of the connecting rod 11 is fixedly connected to the lower surface of the connecting plate 5, so that the pressing block 3 is fixedly connected to the lower side of the connecting plate 5.

[0030] A strip groove 12 is provided on the upper surface of the base 1, which is connected to the pressing groove 10, and the side of the strip groove 12 opposite to the pressing groove 10 is open, so that the cable to be riveted can be placed in the strip groove 12, thereby preventing the cable from moving during the riveting process.

[0031] The arc plate 6 is located directly above the strip groove 12 and cooperates with the strip groove 12. The upper surface of the arc plate 6 is fixedly connected to the limit rod 13. The upper end of the limit rod 13 passes through the connecting plate 5 and is fixedly connected to the limit block 14. A limit spring 15 is sleeved on the limit rod 13. The upper end of the limit spring 15 is fixedly connected to the connecting plate 5, and the lower end of the limit spring 15 is fixedly connected to the arc plate 6, so that the required riveted cable can be pressed and fixed between the arc plate 6 and the strip groove 12 through the cooperation of the arc plate 6 and the strip groove 12. When the spring 15 facilitates the contact between the arc plate 6 and the cable, the connecting plate 5 can drive the pressure block 3 to continue to move downward, thereby realizing further pressing and partial movable yielding function through the elastic force of the spring 15.

[0032] A chute 16 is provided on the lower surface of the bottom plate of the receiving box 7, a discharge hole 17 is provided on the top of the chute 16, and a baffle plate 18 is covered on the lower end of the discharge hole 17. The baffle plate 18 has a U-shaped longitudinal section and is slidably connected in the chute 16. A feed port is provided on the top of the receiving box 7, and a piston is inserted in the feed port to facilitate the injection of lubricant into the receiving box 7, and the baffle plate 18 can limit the outflow of lubricant in the receiving box 7, thereby controlling the output of the lubricant.

[0033] A sliding block 19 is fixedly connected to the upper surface of the moving block 8, and the sliding block 19 is slidably connected in the slide groove 16, and the sliding block 19 cooperates with the baffle plate 18. A return spring 20 is fixedly connected to the side wall of the moving plate 8, and one end of the return spring 20 away from the moving plate 8 is fixedly connected to the side wall of the U-shaped plate 4, so that the moving plate 8 can be slidably connected to the bottom of the receiving box 7, and at the same time, the movement of the baffle plate 18 can be driven by the movement of the position of the moving plate 8, thereby automatically controlling the opening and closing of the discharge hole 17.

[0034] The top plate and side walls of the U-shaped plate 4 are provided with interconnected through holes 21, and a guide wheel 22 is rotatably connected to the side wall of the through hole 21. A rope 23 is fixedly connected to the side wall of the movable plate 8 connected to the return spring 20, and the end of the rope 23 away from the movable plate 8 passes around the guide wheel 22 and is fixedly connected to the upper surface of the connecting plate 5. By moving the connecting plate 5 downward, the movement of the movable plate 8 is controlled, so that the smear cotton 9 moves away from the pressing block 3 by itself.

[0035] Working principle: During the use of the present invention, the piston on the receiving box 7 is removed, and the lubricant is injected into the receiving box 7 through the feed port on the receiving box 7, and then the cable to be riveted is placed in the strip groove 12, and the required riveting position is located in the pressing groove 10, and the hydraulic cylinder 2 is started, so that the hydraulic cylinder 2 drives the connection plate 5 to move downward, and at the same time, the pressure head 3 is pushed downward, so that the pressure head 3 performs riveting processing on the cable, and in the process of the connection plate 5 moving downward, the arc plate 6 is driven to move downward, so that the lower end of the arc plate 6 is located in the strip groove 12, and cooperates with the strip groove 12 to clamp and fix the cable to prevent the cable from moving, and when the connection plate 5 moves downward, the rope 23 is pulled downward, because the rope 23 The length value is limited, so that the rope 23 moves the movable plate 8 to the side of the U-shaped plate 4, which is convenient for the smear cotton 9 to move away from the pressing block 3 and at the same time facilitates the downward movement of the connecting plate 5. When the sliding block 19 contacts the side of the baffle plate 18 away from the pressing block 3, the sliding block 19 pushes the baffle plate 18 to one side, thereby opening the discharge hole 17, allowing the lubricant to slide out through the discharge hole 17 and drip on the smear cotton 9, which is convenient for the smear cotton 9 to apply the lubricant on the pressure head 3, saving manpower and time. When the position of the connecting plate 5 is restored, due to the tension of the reset spring 20, the movable plate 8 is pushed to the side close to the pressure head 3, and at the same time drives the baffle plate 18 to move and cover the discharge hole 17, thereby avoiding waste of resources.

[0036] Embodiment 2

[0037] See also Figure 7 In actual use, the cable may be stuck or jammed in the pressing groove 10 by directly riveting in the pressing groove, thereby causing a malfunction and seriously affecting the use. In addition, for the riveting of cables with different diameters, if the telescopic shaft stroke of the hydraulic cylinder remains unchanged, it will obviously cause the thicker cable to be over-pressed and damaged during riveting. Therefore, it is also very important to monitor the riveting stroke. In this regard, the applicant has made the following improvements:

[0038] A protective shell 24 is installed in the pressing groove 10. The top of the protective shell 24 extends out of the pressing groove 10 and is provided with a mounting flange 25. Bolts 26 pass through the mounting flange 25 and are screwed together with the base 1 to fix the protective shell 24 in the pressing groove 10.

[0039] The inner side of the protective shell 24 is a crimping groove 27, and a crimping through hole 30 is provided at the bottom of the crimping groove 27. A stripping plate 28 is slidably installed in the crimping groove 27. The stripping plate 28 is assembled and fixed with one end of the detection rod 29. The other end of the detection rod 29 passes through the crimping through hole 30, the drainage hole 31, the extrusion inner cylinder 48 of the extrusion cylinder 34, and the bottom support plate 49, and is then installed in the detection inner cylinder 37 of the detection cylinder 43 and assembled and fixed with the pressing head 38.

[0040] The drainage hole 31 is arranged at the bottom of the pressing groove 10 and passes through the base 1. The detection rod 29 is located on the part in the extrusion inner cylinder 48, and is sequentially mounted with a limit ring 32 and an oil absorption sponge ring 33 from top to bottom. The limit ring 32 is fixed on the detection rod 29. The oil absorption sponge ring 33 is supported by an oil absorption sponge and its bottom is close to the top surface of the extrusion platform 47. The top surface of the extrusion platform 47 is an inclined surface inclined downward from left to right, and its lowest end is connected to one end of the drainage pipe 36, and the other end of the drainage pipe 36 is connected to the inside of the storage barrel.

[0041] When in use, the cable to be riveted is placed in the crimping groove 27 and then pressed downward by the pressing block for riveting; during this process, liquid lubricant may drip into the crimping groove 27, and then be introduced into the extrusion inner cylinder 48 through the crimping through hole 30 and the drainage hole 31 and absorbed by the oil absorption sponge ring 33. When the detection rod 29 continues to be pressed down or is pressed down again, the limit ring 32 squeezes the oil absorption sponge ring 33 downward, thereby squeezing out the lubricant in the oil absorption sponge ring 33, and the squeezed lubricant is drawn out through the drainage tube 36 for recycling.

[0042] The base plate 49 is fixed on the base 1 through the base connecting plate 50, and the bottom of the base plate 49 is also assembled and fixed with one end of the detection tube 46. The detection tube 46 has a hollow detection inner tube 37 inside. The pressing head 38 can slide in the axial direction of the detection inner tube 37, and the bottom of the pressing head 38 is in close contact with the top surface of the first airbag 52. The first compression spring 39 is installed inside the first airbag 52, and the inside of the first airbag 52 is connected with the inside of the second airbag 51 through the connecting air pipe. The trigger plate 40 is fixed to the bottom of the second airbag 51. The first airbag 52 and the second airbag 51 are both elastic and filled with air at at least two atmospheres of pressure.

[0043] The second airbag 51 and the first airbag 52 are respectively located on the upper and lower sides of the partition 44, and the partition 44 is fixed in the detection inner cylinder 37; the trigger plate 40 is pressed against the top of the second compression spring 41, and the bottom of the second compression spring 41 is tightly attached to the bottom end surface of the detection inner cylinder 37, and the second compression spring 41 is sleeved on the outside of the travel switch 42, and the trigger end of the travel switch 42 is facing the trigger plate. After the trigger plate moves downward, it can trigger the travel switch 42, and the signal end of the travel switch is communicatively connected to the signal end of the PLC, and the signal end of the PLC is also communicatively connected to the control end of the electromagnetic reversing valve that controls the oil supply direction to the hydraulic cylinder.

[0044] In the initial state, due to the elastic force of the first compression spring and the second compression spring, the first airbag 52 expands to the maximum state, and the second airbag 51 shrinks to the minimum state. The stripping plate 28 is located above the crimping groove 27.

[0045] When in use, the pressure block drives the cable to move downward, so that the pressure block cooperates with the top of the stripping plate to test the cable riveting point, so that the stripping plate moves downward until it reaches the maximum position; at this time, the first compression spring and the second compression spring both store elastic force, and the clamping head 38 presses down the first airbag, the volume of the first airbag reaches the minimum, and the second airbag expands, thereby driving the trigger plate 40 to move downward until the travel switch 42 is triggered, and the travel switch 42 inputs a signal to the PLC, and the PLC determines that the clamping is in place, and then drives the electromagnetic reversing valve controlling the oil supply direction of the hydraulic cylinder to switch the direction, the hydraulic cylinder reverses the oil supply, and the telescopic shaft retracts until it reaches the initial state. In this process, the first compression spring and the second compression spring drive the detection rod to reset, thereby driving the stripping plate 28 to move upward through the elastic force to complete automatic demolding, thereby preventing overpressure during cable riveting and achieving automatic demolding to prevent jamming, thereby improving efficiency, reducing failure rate, and improving product qualification rate.

[0046] The "fixed connection" described in the present invention means that the two interconnected parts are fixed together, generally by welding, screws or gluing; "rotational connection" means that the two parts are connected together and can move relative to each other.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
