[0002] The hydraulic valve block is a complex functional block that can install various hydraulic components and connect the components to each other through internal channels. It is a key component in the hydraulic transmission system.

[0003] For example, the Chinese patent with the authorization announcement number "CN220006925U" and the name "An adjustable fixture for hydraulic valve block processing" can tighten the hydraulic valve block by pushing the motor through two relative No. 1 telescopic cylinders. Its spring can play a buffering role and prevent the hydraulic valve block from being squeezed and damaged by excessive pressure, and can also prevent the hydraulic valve block from being unable to be tightened due to excessive pressure. The motor can drive the hydraulic valve block to rotate to facilitate the processing head to process each surface of it.

[0004] When processing the hydraulic valve block, it is necessary to use a clamp to clamp the hydraulic valve block. For example, in the above-mentioned patent, the hydraulic valve block is clamped by two telescopic cylinders. When processing the surface of a single hydraulic valve block, it is necessary to open the corresponding clamping plate. Then, when processing the next surface, it is necessary to first close the processed clamping plate and then open the next clamping plate. Therefore, the preparation work before processing is increased and the processing efficiency is reduced. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] See also Figure 1-3 The present embodiment provides a hydraulic valve block machining adjustable fixture, comprising a base 1, four rotating plates 2 are rotatably arranged on the base 1, and a plurality of support plates 7 are slidably arranged on the base 1, and each of the support plates 7 is located on both sides of the rotating plate 2, and support columns 6 are fixedly connected to the bottom of the base 1 around the periphery;

[0030] It also includes a plurality of limit assemblies for limiting the position of each support plate 7 so that each support plate 7 can stably clamp and limit the rotating plate 2. The rotating plate 2 is limited by the support plate 7 so that the rotating plate 2 is stably perpendicular to the base 1. The hydraulic valve block is placed in the rotating plate 2, and then the hydraulic valve block is clamped by the clamping assembly. When processing one side of the hydraulic valve block, the limit assembly is moved by pulling the clamping plate 16 on the corresponding side, thereby opening the rotating plate 2 on the corresponding side. At the same time, the clamping assembly clamps and locks the other rotating plates 2, thereby ensuring the stability of the clamping of other surfaces and facilitating operation.

[0031] In an embodiment further provided by the utility model, the limiting assembly includes a connecting plate 8, which is fixedly connected to multiple support plates 7 on the same side, a fixing plate 11 is fixedly connected to the bottom of the connecting plate 8, and a tension spring 9 is fixedly connected to the top of the connecting plate 8, and the tension spring 9 is fixedly connected to the base 1. The connecting plate 8 is pulled by the tension spring 9 so that the support plate 7 generates an upward force, thereby limiting the rotating plate 2.

[0032] The utility model further provides an embodiment, which also includes a locking assembly, which is used to lock the limit assembly. The locking assembly includes a plurality of movable plates 13 slidably arranged on the base 1, and each fixed plate 11 is provided with a guide hole 12 adapted to each movable plate 13.

[0033] In the embodiment provided by the utility model, each movable plate 13 is fixedly connected with a clamping plate 16. Each connecting plate 8 is provided with a clamping groove 10 adapted to the clamping plate 16.

[0034] Specifically, the locking assembly also includes a connecting rope 14, the ends of which are fixedly connected to each movable plate 13, and a plurality of guide rods 15 are fixedly connected to the bottom of the base 1. The guide rods 15 are in active contact with the connecting rope 14, and the movable plate 13 is driven to move synchronously by pulling the clamping plate 16. Since the bottom of the movable plate 13 is an inclined surface, after the movable plate 13 moves, the fixed plate 11 is pushed downward, so that the connecting plate 8 moves synchronously, so that the tension spring 9 is stretched, and the movement of the connecting plate 8 drives the support plate 7 to move downward and out of the base 1, thereby canceling the clamping limit of the rotating plate 2.

[0035] The solution further provided by the utility model also includes multiple clamping components, which include a sliding tube 3 slidably arranged on the rotating plate 2, and the end of the sliding tube 3 is fixedly connected to the clamping plate 4, the clamping plate 4 is located in the rotating plate 2, and the sliding rod 5 is slidably arranged in the sliding rod 5. The hydraulic valve block is first placed between the four rotating plates 2, and an electric telescopic rod (not shown in the figure) is installed at the end of the sliding rod 5, and then the sliding rod 5 is driven to move by the electric telescopic rod. An abutment spring (not shown in the figure) is arranged in the sliding tube 3, and the sliding tube 3 is driven to move by the abutment spring, so that the clamping plate 4 is close to the hydraulic valve block, and then the surface of the hydraulic valve block is clamped, and then the electric telescopic rod is closed and maintained in the extended state.

[0036] When in use, first put the hydraulic valve block between the four rotating plates 2, install an electric telescopic rod (not shown in the figure) at the end of the sliding rod 5, and then drive the sliding rod 5 to move by the electric telescopic rod. An abutment spring (not shown in the figure) is arranged in the sliding tube 3. The sliding tube 3 is driven to move by the abutment spring, so that the clamping plate 4 is close to the hydraulic valve block, and then the surface of the hydraulic valve block is clamped, and then the electric telescopic rod is closed and kept in the extended state;

[0037] When a certain surface needs to be processed, the clamping plate 16 on the corresponding side is pulled, and then the movable plate 13 is driven to move synchronously. Since the bottom of the movable plate 13 is an inclined surface, after the movable plate 13 moves, the fixed plate 11 is pushed to move downward, so that the connecting plate 8 moves synchronously, so that the tension spring 9 is stretched, and the connecting plate 8 moves to drive the support plate 7 to move downward and move out of the base 1, thereby canceling the clamping limit of the rotating plate 2, so that the rotating plate 2 rotates, thereby opening the corresponding clamping plate 4, which is convenient for processing the hydraulic valve block;

[0038] When the clamping plate 16 moves, the other moving plates 13 are pulled to move by the connecting rope 14, so that the other clamping plates 16 move until the other clamping plates 16 are clamped into the corresponding clamping grooves 10, and the other rotating plates 2 are locked. After the clamping plate 16 moves to a suitable position, it is locked by a locking member, such as a bolt.

[0039] When the processing of other processing surfaces is completed, similarly, the corresponding clamping plate 16 is pulled to move the movable plate 13, and the other movable plates 13 are driven away from the fixed plate 11 through the connecting rope 14, and then the connecting plate 8 is pulled upward through the tension spring 9, so that the support plate 7 moves up and the rotating plate 2 is locked and limited.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
