Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic tools. Specifically, it particularly relates to a caliper assembly that facilitates quick replacement of the working head. Background Art

[0002] Shearing heads and crimping heads are necessary tools for conducting wire shearing and continuous crimping during the basic construction and maintenance of power lines in the power industry.

[0003] Currently, in pipeline or cable laying projects, it is usually necessary to shear and then crimp pipelines or cables. At present, shearing tools and crimping tools are separately provided, and two tools need to be equipped for work, which is inconvenient to carry and increases costs. Moreover, when replacing and assembling the die blocks of the current crimping head, it is necessary to pull open the locking device, and then assemble the die blocks by hand. Since the outer surface of the die block fits with the inside of the crimping head, when assembling, if the die block is tilted, it is not convenient to assemble it by hand, thus reducing the assembly efficiency.

[0004] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0005] Regarding the problems in the related art, the utility model proposes a caliper assembly that facilitates quick replacement of the working head to overcome the above-mentioned technical problems existing in the prior related art.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a caliper assembly that facilitates quick replacement of the working head, including a fixing plate. A rotating shaft is fixedly installed inside the fixing plate. Two groups of calipers are rotatably arranged on the outer surface of the rotating shaft. A first working piece is arranged inside one group of the calipers, and a second working piece is arranged inside the other group of the calipers. A reset assembly is fixedly installed inside the calipers.

[0008] Further, the first working piece includes an installation groove, which is opened on one side of one group of the calipers, and a shearing head is fixedly installed inside the installation groove.

[0009] Further, the second working piece includes a spring groove, which is opened inside the other group of the calipers. A spring is fixedly connected to the inner wall of the spring groove. One end of the spring is fixedly connected to a top block, and one end of the top block is fixedly connected to a limiting column.

[0010] The other end of the top block is fixedly connected with a connecting rod. A clamping groove is provided on the outer surface of the connecting rod. A clamping ring is clamped inside the clamping groove. A pulling block is attached to one side of the clamping ring. One side of the pulling block is attached to one side of another set of calipers.

[0011] Further, the second workpiece further includes a sliding groove. A die block is slidably arranged inside the sliding groove. An annular clamping groove is provided on one side of the die block. The outer surface of the limiting column is slidably connected to the inside of the annular clamping groove.

[0012] Further, the reset assembly includes a connecting groove. The connecting groove is opened inside the caliper. A fixed rod is fixedly installed inside the connecting groove. A tension spring is sleeved on the outer surface of the fixed rod.

[0013] The utility model has the following beneficial effects:

[0014] 1. By fixedly installing the fixing plate at the output end of the electro-hydraulic tool, the rotating shaft fixedly installed inside it drives the bottom end of the caliper to fit with the output end of the electro-hydraulic tool. Since the caliper is fixedly installed with the rotating shaft and the fixing plate, and it is a split type with the electro-hydraulic tool, it is convenient to replace the first workpiece or the second workpiece and is convenient to carry.

[0015] 2. By pulling the pulling block to drive the clamping ring attached to one side of it to move, the clamping ring can drive the connecting rod to move in cooperation with the clamping groove. The connecting rod can drive the top block to move. The top block can drive the limiting column to move into the spring groove. Then, by rotating the pulling block, it rotates around the connecting rod so that one side of it fits with the outer surface of the caliper, thus avoiding the spring from pushing the top block to reset. Align the bottom end of the die block with the top end of the sliding groove and press the die block downward to make it slide into the sliding groove, which is convenient for its installation. Then rotate the pulling block again to make it reset, and then it can cooperate with the elastic force of the spring to push the top block to reset, so that it can drive the limiting column to move into the annular clamping groove, thus restricting and fixing the position of the die block and improving the assembly efficiency of the die block.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Please refer to Figures 1-8 As shown, the present utility model is a caliper assembly facilitating quick replacement of the working head, including a fixing plate 1. A rotating shaft 2 is fixedly installed inside the fixing plate 1. Two groups of calipers 3 are rotatably arranged on the outer surface of the rotating shaft 2. A first working piece 4 is arranged inside one group of the calipers 3, and a second working piece 5 is arranged inside the other group of the calipers 3. A reset assembly 6 is fixedly installed inside the calipers 3.

[0031] During use, by fixedly installing the fixing plate 1 with the output end of the electro-hydraulic tool, the rotating shaft 2 fixedly installed inside it drives the bottom end of the caliper 3 to fit with the output end of the electro-hydraulic tool. Since the bottom end of the caliper 3 is relatively arc-shaped and the output end of the electro-hydraulic tool is roller-shaped, when the electro-hydraulic tool is started, it can drive the roller to push the arc surface of the caliper 3, so that the caliper 3 rotates around the rotating shaft 2, enabling the caliper 3 to drive the first working piece 4 or the second working piece 5 arranged at the other end to move relatively, and thus being able to shear or crimp the cable. Since the caliper 3 is fixedly installed with the rotating shaft 2 and the fixing plate 1, and it is a split type with the electro-hydraulic tool, it is convenient to replace the first working piece 4 or the second working piece 5 and convenient to carry it.

[0032] The present utility model fixedly installs the fixing plate 1 with the output end of the electro-hydraulic tool, so that the rotating shaft 2 fixedly installed inside it drives the bottom end of the caliper 3 to fit with the output end of the electro-hydraulic tool. Since the caliper 3 is fixedly installed with the rotating shaft 2 and the fixing plate 1, and it is a split type with the electro-hydraulic tool, it is convenient to replace the first working piece 4 or the second working piece 5 and convenient to carry it.

[0033] In one embodiment, for the above-mentioned first working piece 4, the first working piece 4 includes an installation groove 401. The installation groove 401 is opened on one side of one group of the calipers 3, and a shear head 402 is fixedly installed inside the installation groove 401.

[0034] By starting the electro-hydraulic tool, the roller provided at its output end is driven to move, so that it moves along the arc surface provided at one end of the caliper 3, and the caliper 3 is pushed to rotate around the rotating shaft 2, so as to drive the mounting groove 401 provided at the other end of the caliper 3 to move relatively. When the mounting groove 401 moves, it can drive the shearing head 402 fixedly installed inside it to move, so as to shear the cable, which is relatively convenient.

[0035] In one embodiment, for the above-mentioned second workpiece 5, the second workpiece 5 includes a spring groove 501, the spring groove 501 is opened inside the other group of calipers 3, the inner wall of the spring groove 501 is fixedly connected with a spring 502, one end of the spring 502 is fixedly connected with a top block 503, and one end of the top block 503 is fixedly connected with a limiting column 504;

[0036] The other end of the top block 503 is fixedly connected with a connecting rod 505, a clamping groove 506 is provided on the outer surface of the connecting rod 505, a snap ring 507 is clamped inside the clamping groove 506, a pulling block 508 is arranged in a fitting manner on one side of the snap ring 507, and one side of the pulling block 508 is arranged in a fitting manner with one side of the other group of calipers 3.

[0037] By pulling the pulling block 508, the snap ring 507 arranged in a fitting manner on one side of it is driven to move. When the snap ring 507 moves, it can cooperate with the clamping groove 506 to drive the connecting rod 505 to move. When the connecting rod 505 moves, it can drive the top block 503 fixedly connected to one end of it to move. When the top block 503 moves, it can drive the limiting column 504 fixedly connected to one side of it to move into the spring groove 501. Then, by rotating the pulling block 508, it rotates around the connecting rod 505 so that one side of it fits with the outer surface of the caliper 3, thereby avoiding the spring 502 from pushing the top block 503 to reset, and further improving the stability during the assembly of the caliper assembly that is convenient for quickly replacing the tool head.

[0038] In one embodiment, for the above-mentioned second workpiece 5, the second workpiece 5 further includes a sliding groove 509, a die block 510 is slidably arranged inside the sliding groove 509, an annular clamping groove 511 is opened on one side of the die block 510, and the outer surface of the limiting column 504 is slidably connected to the inside of the annular clamping groove 511.

[0039] When the limit post 504 moves into the spring groove 501, the bottom end of the die block 510 is aligned with the top end of the sliding groove 509, and the die block 510 is pressed downward to slide it into the sliding groove 509, thus facilitating its installation. Then, the pull block 508 is rotated again to reset it, and then it can cooperate with the elastic force of the spring 502 to push the top block 503 to reset, so that it can drive the limit post 504 to move into the internal of the annular clamping groove 511, thereby restricting and fixing the position of the die block 510, and improving the assembly efficiency of the die block 510.

[0040] In one embodiment, for the above-mentioned reset assembly 6, the reset assembly 6 includes a connection groove 601 which is opened inside the caliper 3. A fixing rod 602 is fixedly installed inside the connection groove 601, and a tension spring 603 is sleeved on the outer surface of the fixing rod 602.

[0041] Start the electric hydraulic tool to drive the roller provided at its output end to move, so that it moves along the arc surface opened at one end of the caliper 3, and pushes the caliper 3 to rotate around the rotating shaft 2 as the center, thereby driving the relative movement of the connection groove 601 opened inside it. When the connection groove 601 moves, it can drive the fixing rod 602 fixedly installed inside it to move. When the fixing rod 602 moves, it can drive the tension spring 603 sleeved on its outer surface to stretch. When the electric hydraulic tool drives the roller to reset, with the pulling force of the tension spring 603, the caliper 3 is driven to reset, which is more convenient.

[0042] Through the above technical solutions: 1. By fixedly installing the fixing plate 1 with the output end of the electric hydraulic tool, the bottom end of the caliper 3 driven by the rotating shaft 2 fixedly installed inside it is attached to the output end of the electric hydraulic tool. Since the caliper 3 is fixedly installed with the fixing plate 1 in cooperation with the rotating shaft 2 and is detachably arranged with the electric hydraulic tool, it is convenient to replace the first workpiece 4 or the second workpiece 5 and convenient to carry it.

[0043] 2. By pulling the pull block 508, the clamping ring 507 disposed on one side thereof in a fitting manner is driven to move. The clamping ring 507 can drive the connecting rod 505 to move in cooperation with the clamping groove 506. The connecting rod 505 can drive the top block 503 to move. The top block 503 can drive the limiting post 504 to move into the interior of the spring groove 501. Then, by rotating the pull block 508, it rotates around the connecting rod 505 so that one side thereof fits against the outer surface of the caliper 3, thereby being able to prevent the spring 502 from pushing the top block 503 to reset. Align the bottom end of the die block 510 with the top end of the sliding groove 509, and press down the die block 510 to make it slide into the interior of the sliding groove 509, thereby facilitating its installation. Then, rotate the pull block 508 again to make it reset, and thus it can cooperate with the elastic force of the spring 502 to push the top block 503 to reset, so that it can drive the limiting post 504 to move into the interior of the annular clamping groove 511, thereby being able to limit and fix the position of the die block 510 and improving the assembly efficiency of the die block 510.
