Technical Field
[0001] This utility model relates to the field of hydraulic clamping technology, and in particular to a four-axis turntable hydraulic clamping device with multi-angle adjustment function. Background Technology
[0002] The four-axis rotary table hydraulic clamping device is a machining auxiliary device specifically designed for four-axis rotary tables. It is mainly used to stably clamp workpieces on a four-axis rotary table and achieve multi-angle positioning of the workpiece to meet the needs of high-precision machining.
[0003] Existing four-axis rotary table hydraulic clamping devices only support limited clamping angle and position adjustments. Due to the limited clamping angle and position adjustments, the devices are difficult to adapt to workpieces of various shapes and sizes, thus limiting their versatility in different application scenarios. Utility Model Content
[0004] The purpose of this invention is to provide a four-axis rotary table hydraulic clamping device with multi-angle adjustment function. This device enables the clamping and fixing of workpieces of different shapes at different angles, thereby solving the problem in the prior art that it is not convenient to clamp and fix workpieces of different shapes at different angles.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A four-axis rotary table hydraulic clamping device with multi-angle adjustment function includes a base, a cavity inside the base, pipes fixedly connected through both sides of the base, one end of each pipe communicating with the cavity; two vertical plates, the vertical plates being disposed on the upper end of the base, rotating blocks being rotatably connected inside the vertical plates, a housing being fixedly connected to the upper end of each rotating block, the other end of each pipe communicating with the interior of the housing, and a clamping block being slidably connected inside the housing.
[0007] Preferably, the base has a liquid storage chamber inside, and a pump body is fixedly connected inside the liquid storage chamber, with the output end of the pump body communicating with the inside of the chamber.
[0008] Preferably, a horizontal bar is rotatably connected through one side of the vertical plate, and the horizontal bar is fixedly connected through the rotating block.
[0009] Preferably, the end of the crossbar is provided with a sliding groove, a sliding rod is slidably connected inside the sliding groove, a disc is fixedly connected to one end of the sliding rod, and two locking rods are fixedly connected to the side wall of the disc.
[0010] Preferably, a spring is fixedly connected to the inner wall of the slide groove, and the end of the spring is fixedly connected to the other end of the slide rod.
[0011] Preferably, the side wall of the vertical plate is provided with multiple slots, which are distributed in a circular array, and the slots are slidably connected to the locking rod.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] 1. When clamping and fixing a flat workpiece, manually pull the disc to allow the clamping rods to slide out from two of the slots. Simultaneously, the sliding rod pulls the spring, putting it in a stretched state. Then, manually rotate the housing to make the rotating block rotate inside the vertical plate. At the same time, the rotating block drives the horizontal bar to rotate, and the horizontal bar drives the sliding rod to rotate through the sliding groove. The sliding rod drives the disc and the two clamping rods on its side wall to rotate, rotating the housing from a vertical state to a horizontal state. The clamping blocks slide out from inside the housing and their ends contact the upper end of the flat workpiece. The workpiece is clamped and fixed by the two clamping blocks, which facilitates clamping and fixing workpieces of different shapes at different angles. By changing the angle of the housing, it is easier to adapt to workpieces of different shapes and sizes. This flexibility allows the same clamping device to be used for a variety of workpieces, improving its versatility and adaptability.
[0014] 2. Manually release the disc, and the spring will pull the slide rod to slide. At the same time, the slide rod will drive the disc to slide, so that the locking rod slides into the other two slots, limiting the rotating block and keeping the housing in a horizontal position. When the locking rod slides into the slot, it plays a self-locking role, preventing the housing from rotating or shaking on its own, ensuring the stability of the housing in a vertical or horizontal position, thereby ensuring the stability and reliability of the workpiece during clamping.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-5 A four-axis rotary table hydraulic clamping device with multi-angle adjustment function includes a base 001, an interior cavity 103, and pipes 104 fixedly connected to both sides of the base 001, one end of which communicates with the cavity 103; two vertical plates 002, located on the upper part of the base 001, with rotating blocks 201 rotatably connected inside the vertical plates 002, and a housing 202 fixedly connected to the upper end of the rotating blocks 201; the other end of the pipes 104 communicates with the interior of the housing 202, and a clamping block 203 is slidably connected inside the housing 202. The operator fixes the base 001 to a designated position inside the four-axis rotary table. When a workpiece needs to be clamped, the operator places the workpiece on the upper part of the base 001, and then hydraulic oil is supplied to the cavity 103, flowing through the pipes 104 to the housing 202. Inside, hydraulic oil pushes the clamping block 203, which slides out from inside the housing 202 and its end contacts the side wall of the workpiece. The workpiece is clamped and fixed by the two relatively sliding clamping blocks 203. When it is necessary to clamp and fix a flat workpiece, the housing 202 is manually rotated so that the rotating block 201 rotates inside the vertical plate 002, turning the housing 202 from a vertical state to a horizontal state. Then, the hydraulic oil inside the cavity 103 flows into the housing 202 through the pipe 104. The hydraulic oil pushes the clamping block 203, which slides out from inside the housing 202 and its end contacts the upper end of the flat workpiece. The workpiece is clamped and fixed by the two clamping blocks 203, which facilitates clamping and fixing workpieces of different shapes at different angles. The pipe 104 is a special hydraulic oil delivery hose.
[0023] The base 001 has a liquid storage chamber 101 inside, and a pump body 102 is fixedly connected inside the liquid storage chamber 101. The output end of the pump body 102 is connected to the inside of the cavity 103. The pump body 102 delivers the hydraulic oil inside the liquid storage chamber 101 to the inside of the cavity 103. When it is necessary to extract the hydraulic oil inside the cavity 103, the pump body 102 operates in reverse to draw the hydraulic oil inside the cavity 103 back into the liquid storage chamber 101.
[0024] A horizontal bar 204 is rotatably connected through one side of the vertical plate 002. The horizontal bar 204 is fixedly connected through the rotating block 201. When the rotating block 201 rotates, it drives the horizontal bar 204 to rotate.
[0025] The end of the crossbar 204 is provided with a groove 205, and a slide rod 206 is slidably connected inside the groove 205. One end of the slide rod 206 is fixedly connected to a disc 208, and two locking rods 209 are fixedly connected to the side wall of the disc 208. Both the groove 205 and the slide rod 206 are rectangular. The crossbar 204 drives the slide rod 206 to rotate through the groove 205, and at the same time, the slide rod 206 drives the disc 208 and the two locking rods 209 on its side wall to rotate.
[0026] A spring 207 is fixedly connected to the inner wall of the slide 205. The end of the spring 207 is fixedly connected to the other end of the slide rod 206. The slide rod 206 slides by the elastic pull of the spring 207.
[0027] The side wall of the vertical plate 002 is provided with multiple slots 210, which are arranged in a circular array. The slots 210 are slidably connected to the locking rod 209. Through the cooperation between the locking rod 209 and the slots 210, the rotating block 201 is limited after rotation.
[0028] In this utility model, the operator fixes the base 001 in a designated position inside the four-axis turntable. When it is necessary to clamp the workpiece, the operator places the workpiece on the upper end of the base 001. The hydraulic oil inside the reservoir 101 is delivered to the cavity 103 through the pump body 102. The hydraulic oil inside the cavity 103 flows to the housing 202 through the pipe 104. The hydraulic oil pushes the clamping block 203, which slides out from the housing 202 and its end contacts the side wall of the workpiece. The workpiece is clamped and fixed by the two relatively sliding clamping blocks 203.
[0029] When a flat workpiece needs to be clamped and fixed, manually pull the disc 208 so that the locking rod 209 slides out from the two locking slots 210. At the same time, the slide rod 206 pulls the spring 207, so that the spring 207 is in a stretched state. Then, manually rotate the housing 202 so that the rotating block 201 rotates inside the vertical plate 002. At the same time, the rotating block 201 drives the horizontal bar 204 to rotate. The horizontal bar 204 drives the slide rod 206 to rotate through the slide groove 205. The slide rod 206 drives the disc 208 and the two locking rods 209 on its side wall to rotate, rotating the housing 202 from a vertical state to a horizontal state. Then, manually release the disc 208. The elasticity of the spring 207 pulls the slide rod 206 to slide. At the same time, the slide rod 206 drives the disc 208 to slide, so that the locking rod 209 slides into the other two locking slots 210, limiting the rotating block 201 and keeping the housing 202 in a horizontal state.
[0030] After the housing 202 is adjusted, the hydraulic oil inside the reservoir 101 is delivered to the cavity 103 through the pump body 102. The hydraulic oil inside the cavity 103 flows to the housing 202 through the pipe 104. The hydraulic oil pushes the clamping block 203, which slides out from the housing 202 and its end contacts the upper end of the flat workpiece. The two clamping blocks 203 clamp and fix the vertical workpiece, which facilitates clamping and fixing workpieces of different shapes at different angles.
[0031] When it is necessary to release the clamping of the workpiece, the pump body 102 operates in reverse, drawing the hydraulic oil inside the cavity 103 into the reservoir 101. As the pump body 102 draws out the hydraulic oil, the pressure inside the cavity 103 decreases, forming a suction negative pressure. Due to the presence of the negative pressure, the hydraulic oil inside the housing 202 flows along the pipe 104 to the cavity 103 to fill the gap left by the hydraulic oil drawn out by the pump body 102 inside the cavity 103. As the hydraulic oil inside the housing 202 flows into the cavity 103, the pressure on the clamping block 203 decreases, and at the same time, the negative pressure generates an attractive force. Therefore, the clamping block 203 slides into the housing 202, thereby releasing the clamping of the workpiece.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
