Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic fixtures, and particularly relates to a hydraulically actuated fixture with auxiliary locking. Background Technique

[0002] The seamless steel pipe has a hollow cross-section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water, and certain solid materials. Compared with solid steel such as round steel, when the bending and torsional strength are the same, the seamless steel pipe is lighter in weight and is an economical cross-section steel. It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in construction. Using seamless steel pipes to manufacture annular parts can improve material utilization rate, simplify manufacturing processes, save materials and processing time, and has been widely used. Different industries have different demands for seamless steel pipes, and thus need to process different sizes. The size of the seamless steel pipe is changed by cold drawing. During cold drawing, the steel pipe will become thinner and the wall will also become thinner. Cold drawing dies are required for processing during cold drawing. The existing cold drawing dies are fixedly installed on a fixed seat, and the fixed seat is installed on the surface of the support through bolts. Due to different processing sizes, the dies need to be frequently replaced. The fixed seat installed with bolts is not convenient for quick disassembly, thus consuming more time in replacing the cold drawing dies. Content of the Utility Model

[0003] The purpose of the utility model is to provide a hydraulically actuated fixture with auxiliary locking to solve the problem in the above background technique that the existing cold drawing dies are fixedly installed on a fixed seat, and the fixed seat is installed on the surface of the support through bolts. Due to different processing sizes, the dies need to be frequently replaced. The fixed seat installed with bolts is not convenient for quick disassembly, thus consuming more time in replacing the cold drawing dies.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A hydraulically actuated fixture with auxiliary locking, including an installation table, a clamping assembly, and a driving assembly;

[0005] Among them: A fixed seat is provided on the surface of the installation table, and a cold drawing die is installed in the middle of the surface of the fixed seat;

[0006] The clamping assembly includes electric hydraulic cylinders installed on both sides of the installation table. A telescopic rod is installed inside the electric hydraulic cylinder. A rotating column is rotatably installed at the top of the telescopic rod. A clamping block is installed at the top of the rotating column. The clamping block is tightly connected to both sides of the fixed seat;

[0007] The driving assembly includes an oil tank provided on one side of the fixed seat. An oil pump is installed on the top of the oil tank. A guide oil pipe is installed at one end of the oil pump. A five-way valve is installed at one end of the guide oil pipe. Two oil supply pipes are installed on the surface of the five-way valve. One end of each of the two oil supply pipes is installed on the top and bottom of the electric hydraulic cylinder respectively.

[0008] As a preferred solution of the utility model: a fixing frame is installed on the top of the electric hydraulic cylinder, a sleeve is fixedly installed inside the fixing frame, and two travel grooves are correspondingly opened on the surface of the sleeve.

[0009] As a preferred solution of the utility model: limiting columns are installed on both sides of the sleeve, and the limiting columns are inserted into the travel groove.

[0010] As a preferred solution of the utility model: positioning columns are fixedly connected to both sides of the surface of the mounting platform, mounting holes are opened on both sides of the fixing seat, and the positioning columns are inserted into the mounting holes.

[0011] As a preferred solution of the utility model: the clamping block is detachably connected to the rotating column.

[0012] As a preferred solution of the utility model: a handle is installed on the top of the fixing seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) An electric hydraulic cylinder is installed on both sides of the mounting platform. When the electric hydraulic cylinder is extended, the internal telescopic rod is driven to rise, and the telescopic rod drives the rotating column to follow the jacking, so that the clamping blocks installed on the top of the rotating column are moved away from both sides of the fixed seat, and the locking of the fixed seat is released. When the fixed seat is replaced, the electric hydraulic cylinder drives the telescopic rod to retract, so that the rotating column drives the clamping blocks to clamp and lock both sides of the fixed seat, replacing the bolt fixing installation method, thereby improving the replacement efficiency;

[0015] (2) A fixing frame is installed on the top of the electric hydraulic cylinder, and a sleeve is installed inside the fixing frame. A travel groove is correspondingly opened on the surface of the sleeve. The sleeve slides and penetrates into the travel groove through the limit columns installed on both sides. Since the telescopic rod and the rotating column are rotatably connected, when the telescopic rod drives the rotating column to rise, the rotating column rotates inside the travel groove under the limit of the limit column. The rotating column rotates and rises, so that the clamping block is driven to rise from both sides of the fixed seat and rotate to one side, which is convenient for the placement and replacement of the fixed seat. When the fixed seat needs to be clamped and locked, the telescopic rod drives the rotating column to retract downward. At this time, the rotating column drives the clamping block to rotate to both sides of the fixed seat during the descent process, so as to fix the fixed seat. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 4 , a hydraulic fixture with auxiliary locking, comprising: a mounting table 1, a clamping assembly 4 and a driving assembly 5; a fixed seat 2 is provided on the surface of the mounting table 1, and a cold drawing die 3 is installed in the middle of the surface of the fixed seat 2;

[0023] Please refer to Figure 1 , Figure 2 , the clamping assembly 4 includes electric hydraulic cylinders 41 installed on both sides of the mounting table 1, a telescopic rod 42 is installed inside the electric hydraulic cylinder 41, a rotating column 43 is rotatably installed at the top of the telescopic rod 42, a clamping block 44 is installed at the top of the rotating column 43, and the clamping block 44 is tightly connected to both sides of the fixed seat 2.

[0024] During specific use: Electric hydraulic cylinders 41 are installed on both sides of the mounting table 1. When the electric hydraulic cylinders 41 extend, the telescopic rods 42 inside are driven to rise. The telescopic rods 42 drive the rotating columns 43 to follow and lift, so that the clamping blocks 44 installed at the tops of the rotating columns 43 move away from both sides of the fixed seat 2, releasing the locking of the fixed seat 2. After the fixed seat 2 is replaced, the electric hydraulic cylinders 41 drive the telescopic rods 42 to contract, so that the rotating columns 43 drive the clamping blocks 44 to clamp and lock both sides of the fixed seat 2, replacing the bolt-fixed installation method and improving the replacement efficiency.

[0025] Please refer to Figure 3, the driving component 5 includes an oil tank 51 arranged on one side of the fixed seat 2. An oil pump 52 is installed on the top of the oil tank 51. One end of the oil pump 52 is installed with an oil guide pipe 53. One end of the oil guide pipe 53 is installed with a five-way valve 54. Two oil supply pipes 55 are installed on the surface of the five-way valve 54. One ends of the two oil supply pipes 55 are respectively installed on the top and bottom of the electric hydraulic cylinder 41.

[0026] During specific use: When the oil pump 52 works, it transports the hydraulic oil inside the oil tank 51 through the oil guide pipe 53. After the hydraulic oil passes through the five-way valve 54, the oil circuit direction is controlled. When it is necessary to lift the clamping block 44, the hydraulic oil enters through the oil supply pipe 55 connected to the bottom of the electric hydraulic cylinder 41, so that the oil inside the electric hydraulic cylinder 41 flows back to the oil tank 51 through the top oil supply pipe 55. When it is necessary to clamp and lock the fixed seat 2, the direction of the hydraulic oil is opposite, so that the clamping block 44 clamps the fixed seat 2, thereby providing hydraulic power for the clamping block 44 to lock the clamping.

[0027] Please refer to Figure 1 , Figure 2 , a fixing frame 6 is installed on the top of the electric hydraulic cylinder 41. A sleeve 7 is fixedly installed inside the fixing frame 6. Two stroke grooves 8 are correspondingly opened on the surface of the sleeve 7. Limit posts 9 are installed on both sides of the sleeve 7. The limit posts 9 are inserted inside the stroke grooves 8.

[0028] During specific use: A fixing frame 6 is installed on the top of the electric hydraulic cylinder 41. A sleeve 7 is installed inside the fixing frame 6. Stroke grooves 8 are correspondingly opened on the surface of the sleeve 7. The sleeve 7 is slidably inserted into the stroke grooves 8 through the limit posts 9 installed on both sides. Since the telescopic rod 42 and the rotating column 43 are rotatably connected, when the telescopic rod 42 drives the rotating column 43 to rise, the rotating column 43 rotates upward inside the stroke grooves 8 under the limitation of the limit posts 9. The rotation and rise of the rotating column 43 drive the clamping block 44 to rise from both sides of the fixed seat 2 and rotate to one side, facilitating the placement and replacement of the fixed seat 2. When it is necessary to clamp and lock the fixed seat 2, the telescopic rod 42 drives the rotating column 43 to contract downward. At this time, the rotating column 43 drives the clamping block 44 to rotate to both sides of the fixed seat 2 during the descent, realizing the fixation of the fixed seat 2.

[0029] Please refer to Figure 1 , Figure 4 , positioning columns 10 are fixedly connected to both sides of the surface of the installation table 1. Installation holes 11 are opened on both sides of the fixed seat 2. The positioning columns 10 are inserted inside the installation holes 11.

[0030] During specific use: Positioning columns 10 are connected to both sides of the surface of the installation table 1. When the fixed seat 2 needs to be installed, the positioning columns 10 are inserted inside the installation holes 11 on both sides of the fixed seat 2, so that the installation table 1 is installed and connected to the fixed seat 2 through the positioning columns 10.

[0031] Please refer toFigure 2 The clamping block 44 is detachably connected to the rotating column 43.

[0032] During specific use, the clamping block 44 and the rotating column 43 are detachably connected together, so that the clamping block 44 can be easily replaced.

[0033] See also Figure 1 , Figure 4 A handle 12 is installed on the top of the fixing seat 2.

[0034] During specific use: the handle 12 installed on the top of the fixing base 2 is convenient for taking the fixing base 2 during the replacement process.

[0035] An electric hydraulic cylinder 41 is installed on both sides of the mounting platform 1. When the electric hydraulic cylinder 41 is extended, it drives the internal telescopic rod 42 to rise, and the telescopic rod 42 drives the rotating column 43 to follow the jacking, so that the clamping blocks 44 installed on the top of the rotating column 43 are moved away from both sides of the fixing seat 2, and the fixing seat 2 is unlocked. When the fixing seat 2 is replaced, the electric hydraulic cylinder 41 drives the telescopic rod 42 to contract, so that the rotating column 43 drives the clamping blocks 44 to clamp and lock both sides of the fixing seat 2, replacing the bolt fixing installation method and improving the replacement efficiency.
