[0021] This invention features multiple clamping mechanisms and fixing blocks on a multi-station hydraulic valve body fixture.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Figure 1 This invention illustrates the structure of a multi-station hydraulic valve body tooling. Figure 2 This shows a first structural schematic diagram of the tooling base in this utility model. Figure 3 This invention shows a second structural schematic diagram of the tooling base in this utility model. Figure 4 This diagram shows the third structural schematic of the tooling base in this utility model. Figure 5 It shows Figure 4 Enlarged view of point A in the image. Figure 6 This diagram shows the fourth structural feature of the tooling base in this invention. Figure 7 It shows Figure 6The enlarged view at point B shows that the multi-station hydraulic valve body fixture includes: a fixture base 1, multiple clamping mechanisms 2, multiple first limiting mechanisms 3, and multiple second limiting mechanisms 4. A fixing block 5 is provided on one end of the upper surface of the fixture base 1, and the multiple clamping mechanisms 2 are provided on the upper surface of the fixture base 1, and the multiple clamping mechanisms 2 are evenly spaced from the other end of the upper surface of the fixture base 1 toward the fixing block 5. The distance between the fixing block 5 and an adjacent clamping mechanism 2 forms an installation station 6 for accommodating the valve body, or the distance between two adjacent clamping mechanisms 2 forms an installation station 6 for accommodating the valve body. The first limiting mechanism 3 and the second limiting mechanism 4 are respectively provided on both sides of each installation station 6. In this embodiment, the multi-station hydraulic valve fixture is equipped with three clamping mechanisms 2, three first limiting mechanisms 3, and three second limiting mechanisms 4. The three clamping mechanisms 2 and the fixing blocks 5 are evenly spaced, dividing the fixture base 1 into three installation stations 6. This allows the fixture base 1 to clamp three workpieces at once, reducing the time required for frequent clamping of a single workpiece, significantly shortening the overall processing time, and improving processing efficiency. The distance between two adjacent first limiting mechanisms 3 is equal, and the distance between two adjacent second limiting mechanisms 4 is equal, ensuring that the first limiting mechanisms 3 and the second limiting mechanisms 4 can abut and limit the workpiece placed in the installation station 6 at the corresponding position of each installation station 6. This prevents the workpiece from detaching from the corresponding installation station 6 during use and helps to stably fix the workpiece in the corresponding installation station 6. The two adjacent clamping mechanisms 2, the first limiting mechanism 3, the second limiting mechanism 4, and the tooling base 1 clamp and limit the workpiece placed in the corresponding installation station 6 from five directions. That is, the force is applied to the workpiece from five different directions, which can effectively eliminate the degree of freedom of the workpiece in each direction and reduce the risk of errors caused by the workpiece shaking or shifting during the processing.

[0033] Furthermore, the clamping mechanism 2 includes: a mounting base 21, a first driving component 22, and a clamping block 23; the first driving component 22 is mounted in the mounting base 21, and the clamping block 23 is mounted on the output end of the first driving component 22. The clamping block 23 is driven by the first driving component 22 to move towards or away from the corresponding mounting station 6. In this embodiment, the clamping block 23 is driven by the first driving component 22 to move towards the corresponding mounting station 6, so that the clamping block 23 can abut against the workpiece placed at the mounting station 6, thereby clamping the corresponding workpiece and ensuring that the workpiece can be fixed at the corresponding mounting station 6; conversely, the clamping block 23 is driven by the first driving component 22 to move away from the mounting station 6, so that the clamping block 23 does not contact the workpiece placed at the mounting station 6, thereby releasing the corresponding workpiece, making it convenient for employees or robots to remove the workpiece from the mounting station 6.

[0034] Furthermore, the clamping block 23 is provided with a snap-fit ​​groove 232, and the output end of the first driving component 22 is detachably installed in the snap-fit ​​groove 232. The output end of the first driving component 22 is interference-fitted with the snap-fit ​​groove 232. When the output end of the first driving component 22 is inserted into the snap-fit ​​groove 232, the interference fit generates contact pressure through elastic deformation of the material, forming a frictional torque. That is, when the output end of the first driving component 22 is inserted into the corresponding snap-fit ​​groove 232, both the output end of the first driving component 22 and the clamping block 23 undergo slight elastic deformation, increasing the contact area and friction between them. This prevents relative movement or separation between the output end of the first driving component 22 and the clamping block 23 during use, thus strengthening the connection between them. Secondly, the interference fit between the output end of the first driving component 22 and the clamping block 23 increases the contact area, making it easier to disperse the contact pressure and avoid local stress concentration, further improving the connection strength.

[0035] Furthermore, the mounting base 21 includes two symmetrically distributed mounting blocks 211, each of which has a movable groove 2111, and the clamping block 23 is movably mounted in the movable groove 2111. Both symmetrically distributed mounting blocks 211 are provided with movable grooves 2111, and the two ends of the clamping block 23 are correspondingly mounted in the movable grooves 2111. The upper end face of the clamping block 23 abuts against one side wall of the movable groove 2111, and the lower end face of the clamping block 23 abuts against the other side wall of the movable groove 2111, forming a bidirectional constraint. This eliminates the vertical degree of freedom of the clamping block 23, ensuring that the clamping block 23, when driven by the first driving component 22, can only move along the side wall of the movable groove 2111.

[0036] Furthermore, the clamping block 23 has multiple first protrusions 231 on the side near the mounting station 6. Each first protrusion 231 includes multiple triangular pyramidal protrusions, and the top of each triangular pyramidal protrusion is recessed to form a contact plane. In this embodiment, the clamping block 23 has four first protrusions 231 on the side near the mounting station 6. The four first protrusions 231 correspond to the four apex corners of the clamping block 23. Each first protrusion 231 has multiple triangular pyramidal protrusions, and the array of multiple triangular pyramidal protrusions forms a rectangular area. The special shape of the triangular pyramidal protrusions and the design of the contact plane greatly increase the friction between the clamping block 23 and the workpiece, effectively reducing the risk of relative movement between the workpiece and the clamping block 23 during processing, thereby improving processing accuracy. Secondly, the multiple triangular pyramidal protrusions disperse the clamping force, avoiding workpiece surface damage caused by excessive local pressure, which helps to reduce the risk of workpiece surface damage. Meanwhile, the presence of the contact plane allows the clamping force to be transmitted more evenly to the workpiece surface, further reducing stress concentration and helping to extend the service life of the first protrusion 231.

[0037] Furthermore, the fixing block 5 is provided with a plurality of second protrusions 51 on the side near the mounting station 6. Each of the second protrusions 51 includes a plurality of triangular pyramidal protrusions, and the top of each triangular pyramidal protrusion is recessed to form a contact plane. In this embodiment, the clamping block 23 is provided with four second protrusions 51 on the side near the mounting station 6. The four second protrusions 51 correspond to the four apex corners of the clamping block 23, and each of the second protrusions 51 is provided with a plurality of triangular pyramidal protrusions. The array of the plurality of triangular pyramidal protrusions forms a rectangular area. The special shape of the triangular pyramidal protrusions and the design of the contact plane greatly increase the friction between the clamping block 23 and the workpiece, effectively reducing the risk of relative movement between the workpiece and the clamping block 23 during processing, thereby improving processing accuracy. Secondly, the plurality of triangular pyramidal protrusions disperse the clamping force, avoiding workpiece surface damage caused by excessive local pressure, which helps to reduce the risk of workpiece surface damage. Meanwhile, the presence of the contact plane allows the clamping force to be transmitted more evenly to the workpiece surface, further reducing stress concentration and helping to extend the service life of the second protrusion 51.

[0038] Furthermore, the first limiting mechanism 3 includes a second driving component 31 and a first L-shaped limiting rod 32; the connecting end of the first L-shaped limiting rod 32 is connected to the output end of the first driving component 22, and the first L-shaped limiting rod 32 rotates under the drive of the first driving component 22. The limiting end of the first L-shaped limiting rod 32 is driven by the second driving component 31 to abut against the side wall of the corresponding workpiece. That is, when the second driving component 31 outputs power, it drives the first L-shaped limiting rod 32 to rotate until it is perpendicular to the tooling base 1. At this point, the limiting end of the first L-shaped limiting rod 32 abuts against the side wall of the corresponding workpiece, increasing the friction between the first L-shaped limiting rod 32 and the workpiece and reducing the risk of the workpiece swaying up and down during processing. At the same time, the first L-shaped limiting rod 32 also restricts one direction of movement of the corresponding workpiece. Conversely, when the second driving component 31 outputs power, it drives the first L-shaped limiting rod 32 to rotate until it is parallel to the tooling base 1. At this point, the limiting end of the first L-shaped limiting rod does not abut against the side wall of the corresponding workpiece, thus facilitating the removal of the corresponding workpiece from the installation station 6.

[0039] Furthermore, the second limiting mechanism 4 includes: a third driving component 41 and a second L-shaped limiting rod 42; the connecting end of the second L-shaped limiting rod 42 is connected to the output end of the third driving component 41, and the second L-shaped limiting rod 42 is driven by the third driving component 41 to rotate. The limiting end of the second L-shaped limiting rod 42 is driven by the third driving component 41 to abut against the side wall of the corresponding workpiece. That is, when the third driving component 41 outputs power, it drives the second L-shaped limiting rod 42 to rotate until it is perpendicular to the tooling base 1. At this point, the limiting end of the second L-shaped limiting rod 42 abuts against the side wall of the corresponding workpiece, increasing the friction between the second L-shaped limiting rod 42 and the workpiece and reducing the risk of the workpiece swaying up and down during processing. At the same time, the second L-shaped limiting rod 42 also restricts one direction of movement of the corresponding workpiece. Conversely, when the third driving component 41 outputs power, it drives the second L-shaped limiting rod 42 to rotate until it is parallel to the tooling base 1. At this point, the limiting end of the first L-shaped limiting rod does not abut against the side wall of the corresponding workpiece, thus facilitating the removal of the corresponding workpiece from the installation station 6.

[0040] It should be noted that both the second drive component 31 and the third drive component 41 can be drive motors or drive cylinders, and different drive motors or drive cylinders can be used depending on the application.

[0041] Furthermore, each of the installation stations 6 is provided with multiple limiting blocks 61, and the middle area of ​​each of the fixing blocks 5 protrudes upward to form a limiting boss 611. In this embodiment, each of the installation stations 6 is provided with three limiting blocks 61, which are distributed along the edge of the installation station 6. One limiting block 61 is located on the center line of the installation station 6, and the other two limiting blocks 61 are symmetrically distributed based on the limiting block 61 located at the center of the installation station 6. The middle area of ​​each limiting block 61 protrudes to form a limiting boss 611, which is inserted into the limiting groove at the bottom of the corresponding workpiece. The insertion of the limiting boss 611 into the corresponding limiting groove can effectively limit the rotation or displacement of the workpiece. Moreover, the unique shape and position design of the limiting boss 611 and the limiting groove can clearly define the installation direction and position of the workpiece. This foolproof design can prevent operators from installing the workpiece backwards or in the wrong position, which helps to reduce the risk of operator error.

[0042] Specifically, three workpieces are placed sequentially on the three corresponding mounting stations 6, with the bottom of each workpiece corresponding to the limiting block 61 on the three limiting blocks 61. One side of the first workpiece is pressed against the fixing block 5, one side of the second workpiece is pressed against the side of the clamping mechanism 2 of the first mounting station 6 away from the clamping block 23, and one side of the third workpiece is pressed against the side of the clamping mechanism 2 of the second mounting station 6 away from the clamping block 23. Then, through the terminal output command, the clamping mechanism 2, the first limiting mechanism 3, and the second limiting mechanism 4, upon receiving the command, work simultaneously. That is, the first driving component 22 drives the clamping block 23 to move towards the mounting station 6, so that the clamping block 23 clamps the corresponding workpiece; the second driving component 31 drives the first L-shaped limiting rod 32 to rotate until the first L-shaped limiting rod 32 is perpendicular to the tooling base 1, so that the limiting end of the first L-shaped limiting rod 32 abuts against the side wall of the corresponding workpiece, thereby clamping the corresponding workpiece; the third driving component 41 drives the second L-shaped limiting rod 32 to rotate. The L-shaped limiting rod 42 rotates until it drives the second L-shaped limiting rod 42 to be perpendicular to the tooling base 1, so that the limiting end of the second L-shaped limiting rod 42 abuts against the side wall of the corresponding workpiece, thereby clamping the corresponding workpiece. The two adjacent clamping mechanisms 2, one first limiting mechanism 3, one second limiting mechanism 4 and the tooling base 1 clamp and limit the workpiece placed in the corresponding installation station 6 from five directions, that is, apply force to the workpiece from five different directions, which can effectively eliminate the degree of freedom of the workpiece in each direction and reduce the risk of errors caused by the workpiece shaking or shifting during processing.

[0043] Furthermore, the multi-position hydraulic valve body fixture also includes a rotating mechanism 7. The mounting fixture is mounted on the rotating mechanism 7 and is driven to rotate by the rotating mechanism 7. The rotating mechanism 7 is used to rotate the entire mounting fixture to an appropriate angle. The rotating mechanism 7 includes a placement base for placing the fixture base 1 and a rotating part 72 for driving the fixture base 1 to rotate. Two symmetrically distributed rotating chucks 71 are provided on the placement base. The two chucks are located on opposite sides of the corresponding fixture base 1. One rotating chuck 71 is connected to one end of the corresponding fixture base 1, and the other rotating chuck 71 is connected to the other end of the corresponding fixture base 1. The output end of the rotating part 72 is connected to the center of one of the rotating chucks 71. When the rotating part 72 outputs power, it drives the rotating chuck 71 to rotate, thereby driving the corresponding fixture base 1 to rotate to a specified angle for easy processing.

[0044] In summary, this utility model, by setting multiple clamping mechanisms and fixing blocks on the multi-station hydraulic valve body tooling, and distributing the tooling base evenly at intervals, divides the tooling base into multiple installation stations. This allows the tooling base to clamp multiple workpieces at once, reducing the time required for frequent clamping of a single workpiece, greatly shortening the overall processing time, and improving processing efficiency. This utility model also includes a first limiting mechanism and a second limiting mechanism. The first limiting mechanism is located on one side of the corresponding installation station, and the second limiting mechanism is located on the other side. This allows two adjacent clamping mechanisms, one first limiting mechanism, one second limiting mechanism, and the tooling base to clamp and limit the workpiece placed in the corresponding installation station from five directions. In other words, it applies force to the workpiece from five different directions, effectively eliminating the workpiece's degrees of freedom in each direction and reducing the risk of errors caused by workpiece shaking or displacement during processing.

[0045] Furthermore, the above description provides a detailed introduction to a multi-station hydraulic valve body tooling provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
