Description

Technical Field

[0001] This utility model relates to the field of hydraulic clamping device technology, and in particular to a novel hydraulic clamping device. Background Technology

[0002] A hydraulic clamping device is a device that uses the pressure generated by a hydraulic system to clamp a workpiece. It is widely used in machining, automated production lines, and other fields. The core of a hydraulic clamping device is the hydraulic system. The hydraulic pump converts mechanical energy into hydraulic energy and transmits pressure through hydraulic oil. When hydraulic oil enters the clamping cylinder, it pushes the piston to move, thereby driving the clamping elements (such as jaws, pressure plates, etc.) to apply clamping force to the workpiece. When it is necessary to release, the hydraulic oil flows back through the control valve, the piston moves in the opposite direction, and the clamping elements release the workpiece.

[0003] When hydraulic clamping devices process irregularly shaped workpieces, the workpieces may have inclined or curved surfaces, which may cause uneven force during the stamping process. This can lead to workpiece misalignment or even detachment from the stamping machine. In severe cases, the workpiece may fly towards nearby operators, potentially causing injury. This makes the hydraulic press inconvenient to use and reduces its practicality.

[0004] Therefore, how to design a hydraulic clamping device that can clamp and fix irregular workpieces is a technical problem that technicians need to solve. Utility Model Content

[0027] A curved base plate 202 is provided on the top of the fixed base plate 201. Curved connecting plates 203 are provided at both ends of the curved base plate 202. A curved clamping plate 204 is installed at one end of the curved connecting plate 203. Both the curved base plate 202 and the curved clamping plate 204 are C-shaped. The curved clamping plate 204 is connected to the curved base plate 202 via the curved connecting plates 203. The curved connecting plates 203 and the curved clamping plate 204 are located on both sides of the curved base plate 202 and have a mirror-symmetrical structure. 202, the arc-shaped connecting plate 203 and the arc-shaped clamping plate 204 are integrated into one structure; the hydraulic station 105 drives the two oil cylinders 103 to move synchronously, and the pressure plate 104 is set on the two oil cylinders 103. The auxiliary mechanism 2 is installed on the top of the pressure plate 104. The movement of the oil cylinders 103 drives the pressure plate 104, the arc-shaped bottom plate 202 and the arc-shaped clamping plate 204 to move up and down, so that the arc-shaped bottom plate 202 and the arc-shaped clamping plate 204 are in contact with the surface of the workpiece, thereby realizing the clamping and loosening of the workpiece.

[0028] An adjusting slide 206 is provided on the outer wall of the arc-shaped clamping plate 204. An adjusting groove 211 is provided inside the fixed base plate 201. An adjusting pull plate 209 is installed inside the adjusting groove 211. An adjusting push plate 208 is provided at one end of the adjusting pull plate 209. An adjusting push groove 207 is provided inside the adjusting slide 206. The outer wall of the adjusting push plate 208 slides in contact with the inner wall of the adjusting push groove 207. The adjusting slide 206 is located on the outer wall of the arc-shaped clamping plate 204. The adjusting pull plate 209 is an arc-shaped plate. By adjusting the position of the adjusting pull plate 209, the position of the adjusting push plate 208 inside the adjusting push groove 207 is adjusted, thereby adjusting the position of the arc-shaped clamping plate 204 so that the arc-shaped clamping plate 204 fits against the surface of the irregular workpiece. With the help of the arc-shaped connecting plate 203, different irregular workpieces can be clamped and fixed.

[0029] A limiting baffle 210 is provided at one end of the adjusting pull plate 209. The outer wall of the limiting baffle 210 slides in contact with the inner wall of the adjusting slide groove 211. An elastic arc plate 212 is provided on the side wall of the limiting baffle 210. A limiting block 213 is provided on the outer wall of the elastic arc plate 212. A limiting groove 215 adapted to the shape of the limiting block 213 is provided inside the adjusting slide groove 211. The limiting block 213 is fixedly sleeved inside the limiting groove 215. A toggle arc plate 214 is provided at one end of the elastic arc plate 212. The elastic arc plate 212 is an arc-shaped plate. The elastic arc plate 212 is located at the limiting block 214. The 13 sidewalls are mirror-symmetrical, and the shape of the limiting block 213 is adapted to the shape of the limiting groove 215. Under the action of the elastic arc plate 212, the limiting block 213 can be fixedly fitted into the limiting groove 215, thereby locking the position of the adjusting plate 209. Since the limiting groove 215 is located inside the adjusting slide 211 and is distributed in a linear array, by fixing the limiting block 213 into the limiting groove 215 at different positions, it is beneficial to fix the adjusting plate 209 into different positions of the adjusting slide 211.

[0030] The pressure plate 104 has a fixing slot 106 inside, and the fixing base plate 201 is fixedly fitted inside the fixing slot 106. The fixing slot 106 has a limit hole 107 inside, and the bottom of the fixing base plate 201 has a limit rod 216. The limit rod 216 is slidably fitted inside the limit hole 107. The shape of the fixing slot 106 is adapted to the shape of the fixing base plate 201. By fixing the fixing base plate 201 inside the fixing slot 106, it is easy to install the auxiliary mechanism 2 inside the pressure plate 104. The shape of the limit rod 216 is adapted to the shape of the limit hole 107. The limit rod 216 is located at the bottom of the fixing base plate 201. By fixing the limit rod 216 inside the limit hole 107, it is easy to limit the position of the fixing base plate 201.

[0031] Both the inner walls of the arc-shaped base plate 202 and the arc-shaped clamping plate 204 are provided with anti-slip pads 205, which are linearly arrayed on the inner walls of the arc-shaped base plate 202 and the arc-shaped clamping plate 204. The anti-slip pads 205 are made of rubber and can protect the workpiece from slippage when the arc-shaped base plate 202 and the arc-shaped clamping plate 204 clamp the workpiece, preventing wear on the workpiece surface caused by the arc-shaped base plate 202 and the arc-shaped clamping plate 204. In addition, they can increase the friction between the arc-shaped base plate 202 and the arc-shaped clamping plate 204 and the workpiece, preventing the workpiece from sliding during the clamping process and preventing any impact on the processing of the workpiece.

[0032] In this embodiment, the limiting rod 216 is slidably inserted into the limiting hole 107, and then the fixed base plate 201 is installed into the fixed slot 106. The auxiliary mechanism 2 is then installed on top of the pressure plate 104. The position of the adjusting pull plate 209 in the adjusting groove 211 is adjusted according to the shape of the workpiece, simultaneously driving the adjusting push plate 208 in the adjusting push groove 207, thereby adjusting the position of the arc-shaped clamping plate 204 so that it fits against the workpiece surface. Then, the elasticity of the elastic arc plate 212 is used to fix the retaining sleeve of the limiting block 213. The position of the adjusting pull plate 209 is fixed in the limiting slot 215. Then, the two oil cylinders 103 are driven to move synchronously through the hydraulic station 105. The pressure plate 104 is set on the two oil cylinders 103. The auxiliary mechanism 2 is installed on the top of the pressure plate 104. The movement of the oil cylinder 103 drives the pressure plate 104, the arc-shaped base plate 202 and the arc-shaped clamping plate 204 to move up and down, so that the arc-shaped base plate 202 and the arc-shaped clamping plate 204 fit with the surface of the workpiece. This can prevent the workpiece from being misaligned due to uneven force during the stamping process, thereby realizing the clamping and loosening of irregular workpieces.
