Description

Technical Field

[0001] This utility model relates to the field of hydraulic component drilling technology, and in particular to a drilling tool for hydraulic component production. Background Technology

[0002] Oil distribution plate, such as Figure 4 As shown, this is an accessory for a certain type of hydraulic pump. In a hydraulic motor or pump, it plays the role of distributing high and low oil circuits, so that when the high-pressure oil in the motor or pump is in operation, it outputs torque, and when the low-pressure oil (return oil) is in operation, it discharges the high-pressure oil in the plunger chamber where the torque output stops.

[0003] After the distribution plate is manufactured, it needs to be drilled to install it on the pump housing. Since the distribution plate is mostly disc-shaped, a clamp is needed to hold it when drilling. Currently, most clamps hold it from both sides, which can ensure its stability, but the arrangement of the clamps is inconvenient. At present, there are very few clamps designed for the shape of the distribution plate. Therefore, this application proposes a drilling fixture for hydraulic component production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drilling tooling for the production of hydraulic components.

[0005] An embodiment of this utility model provides a drilling fixture for hydraulic component production, comprising:

[0006] A base, on which a lifting mounting plate is mounted, and at the bottom of the mounting plate are multiple drilling machines;

[0007] The oil distribution plate limiting structure is mounted on a support plate on the base. The support plate has multiple through holes. The upper end of the support plate is coaxially fixedly connected to a limiting post and an arc-shaped block that are matched with the oil distribution plate. The oil distribution plate can be fitted onto the limiting post and the arc-shaped block. The bottom of the mounting plate is equipped with a retractable pressure plate located below the drilling machine. The pressure plate can first abut against the oil distribution plate and press it.

[0008] Furthermore, a bracket is installed on the upper end of the base, a cylinder is installed on the bracket, a connecting rod is installed on the output end of the cylinder, and the connecting rod is fixedly connected to the upper end of the mounting plate.

[0009] Furthermore, two guide rods are fixed to the upper end of the mounting plate, and the guide rods pass through the bracket and are slidably connected to it.

[0010] Furthermore, the drilling machine includes a motor mounted on the bottom of the mounting plate, and a drill bit is mounted on the output end of the motor.

[0011] Furthermore, a support column is installed on the base, and the support plate is installed on the support column.

[0012] Furthermore, a rectangular sleeve is fixed to the bottom of the mounting plate, a rectangular rod is slidably connected inside the rectangular sleeve, a pressure plate is fixed to the bottom of the rectangular rod, and a spring is fixed to the pressure plate and the rectangular sleeve.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model utilizes the shape of the oil distribution plate to set a limiting post and an arc block, which can limit the oil distribution plate in the horizontal direction, making it difficult to move. It also makes it more convenient to pick up and put down the oil distribution plate, without the need to set up additional clamps in the horizontal direction. The reaction force of the spring makes the pressure plate press tightly against the oil distribution plate, ensuring stability during drilling. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a drilling fixture for hydraulic component production, comprising:

[0022] The base 1 has a lifting mounting plate 5 installed on it. A bracket 2 is installed on the upper end of the base 1. A cylinder 3 is installed on the bracket 2. A connecting rod is installed on the output end of the cylinder 3. The connecting rod is fixedly connected to the upper end of the mounting plate 5. The extension and retraction of the output end of the cylinder 3 can drive the connecting rod and the mounting plate 5 to move up and down.

[0023] To ensure more stable vertical movement of the mounting plate 5, two guide rods 4 are fixed to the upper end of the mounting plate 5. The guide rods 4 pass through the bracket 2 and are slidably connected to it. The vertical movement of the mounting plate 5 is guided by the guide rods 4, thereby achieving stable vertical movement of the mounting plate 5.

[0024] Multiple drilling machines 6 are installed at the bottom of the mounting plate 5, and the drilling machines 6 are set corresponding to the through holes 10. The drilling machine 6 includes a motor installed at the bottom of the mounting plate 5, and a drill bit is installed at the output end of the motor. The drilling machine 6 is existing technology.

[0025] The oil distribution plate limiting structure is installed on a support plate 9 on a base 1. A support column 7 is installed on the base 1, and the support plate 9 is installed on the support column 7. Multiple through holes 10 are provided on the support plate 9. The through holes 10 correspond to the positions where the oil distribution plate needs to be drilled. In this way, after the drill bit penetrates the oil distribution plate, it can enter the through hole 10, ensuring that the oil distribution plate is drilled through and protecting the drill bit.

[0026] The upper end of the support plate 9 is coaxially fixedly connected with a limiting post 8 and an arc-shaped block 15 that are designed to match the oil distribution plate. The oil distribution plate can be fitted onto the limiting post 8 and the arc-shaped block 15. In this way, by using the shape of the oil distribution plate to set the limiting post 8 and the arc-shaped block 15, the oil distribution plate can be limited in the horizontal direction, making it difficult to move. It is also more convenient to pick up and put down the oil distribution plate without the need to set up additional clamps in the horizontal direction.

[0027] A retractable pressure plate 12 is installed at the bottom of the mounting plate 5 and is located below the drilling machine 6. The pressure plate 12 can first abut against and press against the oil distribution plate. A rectangular sleeve 11 is fixed at the bottom of the mounting plate 5. A rectangular rod 13 is slidably connected inside the rectangular sleeve 11. The pressure plate 12 is fixed at the bottom of the rectangular rod 13. A spring 14 is fixed on the pressure plate 12 and the rectangular sleeve 11. When the mounting plate 5 moves down, the pressure plate 12 first abuts against the upper end of the oil distribution plate. As the mounting plate 5 continues to move down, there is relative movement between the rectangular rod 13 and the rectangular sleeve 11. The spring 14 is compressed. The reaction force of the spring 14 makes the pressure plate 12 press tightly against the oil distribution plate. Since the pressure plate 12 is located below the mounting plate 5, the equipment occupies less space and the structure is more compact.

[0028] The downward movement of the mounting plate 5 causes the drilling machine 6 to move downward, which can drill holes in the oil distribution plate. Setting up multiple drilling machines 6 can improve the drilling efficiency of the oil distribution plate.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
