Description

Technical Field

[0001] This utility model relates to a tooling fixture, specifically a tooling fixture for testing hydraulic components. Background Technology

[0002] Hydraulic components are all elements used in hydraulic systems, such as hydraulic pumps, hydraulic motors, hydraulic cylinders, hydraulic valves, and boosters. They can be classified as follows: power components, such as hydraulic pumps; control components, such as relief valves, sequence valves, and directional valves; actuators, such as hydraulic motors and hydraulic cylinders; and auxiliary components, such as oil tanks and pipelines. Tooling fixtures are one type of tooling for inspecting hydraulic components. Existing tooling fixtures, with their single clamping structure, are only suitable for handling hydraulic components of one shape. To handle hydraulic components of another shape, they need to be changed, resulting in low efficiency and affecting performance. Therefore, a new tooling fixture for inspecting hydraulic components needs to be designed to solve this problem. Utility Model Content

[0003] The purpose of this utility model is to provide a tooling fixture for testing hydraulic components, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A tooling fixture for testing hydraulic components includes a support plate, on which vertical plates are symmetrically mounted. A placement plate is mounted on the end of each vertical plate away from the support plate, and placement blocks are symmetrically mounted on the placement plate. The support plate has a mounting cavity in which a drive assembly is installed. A rotating shaft and a limiting rod are respectively mounted on the symmetrically mounted vertical plates. A drive rod is fixedly mounted on the rotating shaft. A connecting rod is mounted on the end of the drive rod near the placement block, and a clamping plate is mounted on the end of the connecting rod away from the drive rod. A pressing plate is provided on one side of the limiting rod. A guide groove is formed on the pressing plate, and the guide groove consists of a vertical groove and an inclined groove, which are connected. The end of the limiting rod away from the vertical plate extends into the guide groove and slides against the inner wall of the guide groove. A transmission assembly is mounted on the drive assembly, and the end of the transmission assembly away from the drive assembly is connected to the drive rod and the pressing plate.

[0006] As a further embodiment of this utility model: the driving assembly includes a driving component, which is installed in the mounting cavity. A driving shaft is installed at the output end of the driving component. The end of the driving shaft away from the driving component passes through the mounting cavity, and the driving component is used to drive the driving shaft to rotate.

[0007] As a further embodiment of this utility model: the transmission assembly includes a threaded rod, one end of which is connected to the drive shaft away from the drive component, and the other end is rotatably connected to the placement plate. A threaded block is threadedly connected to the threaded rod, and a first mounting rod and a second mounting rod are mounted on the threaded block. The end of the first mounting rod away from the threaded block is hinged to the drive rod, and the end of the second mounting rod away from the threaded block is hinged to the pressing plate.

[0008] As a further embodiment of this utility model: an elastic component is installed on the drive rod, and the end of the elastic component away from the drive rod is connected to the placement plate.

[0009] As a further embodiment of this utility model, the driving component is a stepper motor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is used to fix the hydraulic component, the hydraulic component is placed on the placement block on one side of the placement plate. The driving component drives the drive shaft connected to it to rotate. The rotation of the drive shaft drives the threaded rod to rotate. The rotation of the threaded rod, under the action of the thread, drives the threaded block connected to it to move. During the downward movement of the threaded block, the first mounting rod and the second mounting rod respectively drive the drive rod to rotate and the pressing plate to move downward. During the rotation of the drive rod around the rotating shaft, the clamping plate of one end of the connecting rod moves. The clamping plate moves towards the workpiece side on the placement block, and the clamping plate pushes the workpiece at one end to move a certain distance. The elastic component is also compressed during the rotation of the drive rod, generating a certain elastic force. During this process, the second mounting rod drives the pressing plate to move. During the downward movement, as the limiting rod slides in the inclined groove, the pressing plate moves closer to the workpiece, causing the top of the pressing plate to move to the upper side of the workpiece. When the limiting rod slides in the vertical groove, the pressing plate moves downward to press and fix the workpiece. Combined with the clamping plate's limiting on one side, the workpiece is pressed and fixed, improving its stability. When it is necessary to contact and fix the workpiece, the drive component drives the drive shaft to reverse, causing the threaded block to move downward and driving the clamping plate and pressing plate away from the workpiece.

During the downward movement, as the limiting rod 13 slides in the inclined groove 20, the pressing plate 15 moves towards the workpiece side, so that the top of the pressing plate 15 moves to the upper side of the workpiece. When the limiting rod 13 slides in the vertical groove, the pressing plate 15 moves downward to press and fix the workpiece. Combined with the limiting of one side by the clamping plate 11, the workpiece is pressed and fixed, improving the stability of the workpiece.

[0018] As an embodiment of the present invention, the driving assembly includes a driving component 4, which is installed in the mounting cavity 3. A driving shaft 5 is installed at the output end of the driving component 4. The end of the driving shaft 5 away from the driving component 4 passes through the mounting cavity 3, and the driving component 4 is used to drive the driving shaft 5 to rotate.

[0019] In this embodiment, the driving component 4 drives the driving shaft 5 connected to it to rotate. The rotation of the driving shaft 5 drives the transmission component connected to it to operate. When fixing the workpiece, the transmission component drives the first mounting rod 18 and the second mounting rod 16 to drive the driving rod 9 to rotate and the pressing plate 15 to move downward, respectively. During the rotation of the driving rod 9 around the rotating shaft 8, it drives the clamping plate 11 of the connecting rod 10 to move. The clamping plate 11 moves towards the workpiece side on the placement block 12. The second mounting rod 16 drives the pressing plate 15 to move. During the downward movement, as the limiting rod 13 slides in the inclined groove 20, the pressing plate 15 moves towards the workpiece side, so that the top of the pressing plate 15 moves to the upper side of the workpiece. When the limiting rod 13 slides in the vertical groove, the pressing plate 15 moves downward to press and fix the workpiece. With the clamping plate 11 limiting one side, the workpiece is pressed and fixed, improving the stability of the workpiece.

A threaded block 7 is threadedly connected to the threaded rod 6. A first mounting rod 18 and a second mounting rod 16 are mounted on the threaded block 7. The end of the first mounting rod 18 away from the threaded block 7 is hinged to the drive rod 9. The end of the second mounting rod 16 away from the threaded block 7 is hinged to the pressing plate 15. An elastic member 21 is mounted on the drive rod 9. The end of the elastic member 21 away from the drive rod 9 is connected to the placement plate.

[0022] In this embodiment, the rotation of the drive shaft 5 drives the threaded rod 6 to rotate. The rotation of the threaded rod 6, under the action of the thread, drives the connected threaded block 7 to move. During the downward movement of the threaded block 7, the first mounting rod 18 and the second mounting rod 16 respectively drive the drive rod 9 to rotate and the pressing plate 15 to move downward. During the rotation of the drive rod 9 around the rotating shaft 8, the clamping plate 11 of the connecting rod 10 moves. The clamping plate 11 moves towards the workpiece on the placement block 12, and pushes the workpiece at one end a certain distance. The elastic component 21 is also compressed during the rotation of the drive rod 9, generating a certain elastic force. During this process... The second mounting rod 16 drives the pressing plate 15 to move. During the downward movement, as the limiting rod 13 slides in the inclined groove 20, the pressing plate 15 moves closer to the workpiece, so that the top of the pressing plate 15 moves to the upper side of the workpiece. When the limiting rod 13 slides in the vertical groove, the pressing plate 15 moves downward to press and fix the workpiece. In conjunction with the clamping plate 11 limiting one side, the workpiece is pressed and fixed, which improves the stability of the workpiece.

During the rotation of the driving rod 9 around the rotating shaft 8, the clamping plate 11 of the connecting rod 10 moves. The clamping plate 11 moves towards the workpiece side closer to the placement block 12, and the clamping plate 11 pushes the workpiece at one end to move a certain distance. The elastic component... 21 During the rotation of the drive rod 9, it will also be compressed and generate a certain elastic force. During this process, the second mounting rod 16 drives the pressing plate 15 to move. During the downward movement, as the limiting rod 13 slides in the inclined groove 20, the pressing plate 15 moves closer to the workpiece, so that the top of the pressing plate 15 moves to the upper side of the workpiece. When the limiting rod 13 slides in the vertical groove, the pressing plate 15 moves downward to press and fix the workpiece. Together with the clamping plate 11 limiting one side, the workpiece is pressed and fixed, which improves the stability of the workpiece. When it is necessary to contact and fix the workpiece, the drive component 4 drives the drive shaft 5 to reverse, so that the threaded block 7 moves downward and drives the clamping plate 11 and the pressing plate 15 away from the workpiece.
