Description

Technical Field

[0001] This utility model belongs to the field of clamping technology, and specifically relates to a clamping mechanism for processing PVC explosion-proof flexible tube devices. Background Technology

[0002] PVC explosion-proof flexible conduit is a type of metal corrugated explosion-proof flexible conduit with an outer PVC plastic sheath. The core explosion-proof structure is a corrugated metal pipe made of stainless steel or galvanized steel, which is responsible for providing explosion-proof performance, mechanical strength, and grounding continuity. The outer PVC sheath is mainly used to enhance corrosion resistance, provide additional mechanical protection, and serve as an insulating outer layer. The entire assembly consists of a metal pipe, a sheath, and an explosion-proof connector.

[0003] Currently, when installing explosion-proof joints at both ends of PVC explosion-proof flexible conduits, two sets of clamps are required. One set is a horizontal moving clamp for the PVC explosion-proof flexible conduit, and the other set is used to pull the PVC explosion-proof flexible conduit to insert it into the joint. The traditional horizontal moving clamp has a fixed structure, with a basic structure consisting of a travel moving device connected to two fixed clamping arms. However, this has certain problems in use. For example, when pulling the clamp to insert the PVC explosion-proof flexible conduit into the explosion-proof joint, the horizontal clamp is also clamped on the surface of the PVC explosion-proof flexible conduit. When pulling the conduit, the position of the horizontal moving clamp remains unchanged, and the surface of the conduit will rub hard against the clamping arms of the horizontal moving clamp. Therefore, the two are prone to mutual wear, causing damage to the surface of the conduit. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping mechanism for processing PVC explosion-proof flexible tube devices, which has the advantages of wear resistance and strong applicability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a clamping mechanism for processing PVC explosion-proof flexible tube devices, including a base, a first clamping seat provided on the top of the base, two first clamping seats, a second clamping seat provided on the top of the first clamping seat, multiple equidistant universal grooves provided on both the first and second clamping seats, universal balls slidably connected inside the universal grooves, an adjusting seat provided at the bottom of the first clamping seat, an adjusting mechanism provided inside the adjusting seat, and a first adjusting screw threadedly connected to the top of the first clamping seat and threadedly connected to the second clamping seat.

[0006] The above technical solution is as follows: This utility model has universal grooves on both the first and second clamping seats, with universal balls slidably connected inside the universal grooves. When the two first and two second clamping seats clamp the pipe fitting, and the external tension clamp pulls the pipe fitting, the pipe fitting is positioned between the universal balls inside the first and second clamping seats, causing the universal balls to roll within the universal grooves. This prevents pipe fitting wear and improves processing safety. An adjustment mechanism is designed inside the adjusting seat to adjust the distance between the two first clamping seats. The distance between the first and second clamping seats can be adjusted via the first adjusting screw, making it suitable for clamping and fixing pipe fittings of different diameters, thus improving applicability.

[0007] The present invention is further configured such that the adjusting mechanism includes a second adjusting screw rotatably connected inside the adjusting seat, the surface of the second adjusting screw being threadedly connected to a connecting block slidably connected to the adjusting seat, and the top of the connecting block being bolted to the bottom of the first clamping seat.

[0008] The above technical solution is adopted: when the second adjusting screw is rotated, the second adjusting screw can drive the connecting block to move, and the movement of the connecting block can drive the first clamping seat to move at the top of the adjusting seat, thereby achieving the purpose of adjusting the distance between the two first clamping seats.

[0009] The present invention is further configured such that limiting guide rods are symmetrically mounted on the top of the first clamping seat, and the limiting guide rods are slidably connected to the second clamping seat.

[0010] Using the above technical solution: when the first adjusting screw is rotated, the distance between the second clamping seat and the first clamping seat is adjusted, and the limiting guide rod can slide and limit the second clamping seat, so as to facilitate the smooth adjustment of the second clamping seat and the adjustment of the distance between the first clamping seat and the second clamping seat.

[0011] The present invention is further configured such that a support seat is provided at the top of the base, a first connecting rod is symmetrically rotatably connected inside the support seat and fixedly sleeved with the adjusting seat, and a movable seat is slidably connected to the base at the bottom of the support seat.

[0012] The above technical solution allows for the convenient fixing of the adjustment seat inside the support seat. When the first connecting rod rotates, it can drive the angle of the support seat to rotate, thereby realizing the opening and closing of the clamp arm of the fixture. The movable seat is installed at the bottom of the support seat. When the movable seat moves, it can drive the support seat to move, so that one end of the pipe fitting can be inserted into the connector and moved to the next step for processing.

[0013] The present invention is further configured such that a hydraulic telescopic rod is embedded in one end of the base, one end of the hydraulic telescopic rod is fixedly connected to the movable seat, and a limiting block is bolted inside the base and fixedly sleeved with the hydraulic telescopic rod.

[0014] The above technical solution is adopted: when the hydraulic telescopic rod is working, it can drive the movable seat to move inside the base, from the pipe fitting insertion process to the pipe fitting joint and pipe fitting clamping process.

[0015] The present invention is further configured such that a second connecting rod is symmetrically rotatably connected inside the support base, and one end of the first connecting rod and one end of the second connecting rod both penetrate to the outside of the support base and are respectively fixedly sleeved with a first gear and a second gear, the first gear and the second gear meshing, and the two second gears meshing with each other.

[0016] The above technical solution is adopted as follows: when the second connecting rod rotates, it can drive the second gear fixedly sleeved with the second connecting rod to rotate. Under the action of another second gear, it drives the other second connecting rod to rotate in the opposite direction. Under the action of the first gear, it simultaneously drives the two first connecting rods to rotate in opposite directions, so that the two first connecting rods drive the two adjusting seats to rotate inside the support seat, so that the two adjusting seats can be unfolded and merged with each other to complete the clamping and releasing action.

[0017] The present invention is further configured such that a hydraulic cylinder is assembled on the other side of the support base, and a toothed plate is fixedly connected to the output end of the hydraulic cylinder, and a transmission gear that is fixedly sleeved with the second connecting rod is engaged at the top of the toothed plate.

[0018] The above technical solution is adopted as follows: When the hydraulic cylinder is working, it can drive the toothed plate to move back and forth. The toothed plate can drive the transmission gear to rotate back and forth. Under the action of the transmission gear, it can drive a second connecting rod to rotate back and forth, so as to realize the purpose of opening and closing the two adjusting seats inside the adjusting support.

[0019] The present invention is further configured such that a sliding groove is formed on the surface of the toothed plate, and a sliding guide block fixedly connected to the support base is slidably connected inside the sliding groove.

[0020] Using the above technical solution: when the toothed plate moves, the sliding groove and the sliding guide block can limit the sliding of the toothed plate.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model has universal grooves on both the first clamping seat and the second clamping seat, and universal balls are slidably connected inside the universal grooves. When the two first clamping seats and the two second clamping seats clamp the pipe, the external tensioning clamp pulls the pipe. The pipe is between the universal balls inside the first clamping seat and the two second clamping seats, which drives the universal balls to roll inside the universal groove, thereby avoiding wear on the pipe and improving the safety of processing.
