Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a movable tooling hydraulic support column. Background Technology

[0002] In CNC machining, irregular blanks are often encountered during small-batch trial production, especially sand mold blanks, where the error often reaches the millimeter level. This leads to insufficient or excessive support during machining, causing deformation and seriously affecting machining quality and yield. In the past, the solution was to manually grind the support parts for excessive support and fill the gaps for insufficient support. This method was troublesome, labor-intensive, time-consuming, and inefficient. Summary of the Invention

[0003] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model discloses a movable tooling hydraulic support column.

[0004] Technical solution: The movable tooling hydraulic support column of this utility model includes a cylinder housing, in which a first cylinder and a second cylinder are provided. The first cylinder is a pressurizing cylinder with a built-in pressurizing piston, and the second cylinder is a supporting cylinder with a built-in supporting piston. The first cylinder and the second cylinder are connected through a cylinder passage to realize oil flow between the two cylinders.

[0005] The inner end of the pressurizing piston is equipped with a spring, and the outer end is connected to a pressurizing button.

[0006] The outer end of the support piston extends vertically upward and connects to the support claw;

[0007] The cylinder passage is equipped with an oil circuit switch. Pressing the pressurization button allows hydraulic oil to enter the second cylinder, which then supports the support claw. The oil circuit switch closes the cylinder passage, thus locking the support.

[0008] Furthermore, the first and second oil cylinders are arranged side by side in parallel, with their tops extending through the cylinder housing.

[0009] Furthermore, the hydraulic cylinder passage is positioned laterally between the first and second hydraulic cylinders. The hydraulic circuit switch moves within the hydraulic cylinder passage to close or connect it. The hydraulic circuit switch passes through the hydraulic cylinder housing and is connected to a hydraulic circuit release button and a hydraulic circuit lock button at its ends, respectively. The hydraulic cylinder passage is closed or connected by pressing the hydraulic circuit release button and the hydraulic circuit lock button.

[0010] Furthermore, the support claw is sleeved on the outer end of the support piston and is a detachable and replaceable support claw of multiple models.

[0011] Furthermore, the bottom of the cylinder housing is provided with a magnetic base, and the magnetic base is provided with a magnetic switch.

[0012] Furthermore, the cylinder housing and the magnetic base are connected by a dovetail groove.

[0013] Beneficial effects: Compared with the prior art, the advantages of this utility model are: it realizes the transformation from the original manual operation and manual adjustment of the relationship between the product and the support to semi-automatic mechanized operation. Because the hydraulic damping has a more delicate feel and more precise adjustment, it can be made to fit closely to the product support surface, avoiding the mismatch between the product and the tooling support caused by manual operation, improving the product qualification rate and processing quality, significantly reducing operation time, and improving production efficiency.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-5 The movable tooling hydraulic support column shown includes a cylinder housing 1, with a magnetic base 13 at the bottom of the cylinder housing 1. A magnetic switch 14 is mounted on the magnetic base 13. The cylinder housing 1 and the magnetic base 13 are connected by a dovetail groove. First, place the magnetic base 13 below the position of the product requiring support. Rotate the magnetic switch 14 to magnetically attach the base to the tooling table. Then, install the cylinder housing 1.

[0021] The cylinder housing 1 is provided with a first cylinder 2 and a second cylinder 3. The first cylinder 2 is a pressurizing cylinder with a built-in pressurizing piston 5. The second cylinder 3 is a supporting cylinder with a built-in supporting piston 6. The first cylinder 2 and the second cylinder 3 are connected through the cylinder passage 4 to realize the oil flow between the two cylinders.

[0022] The inner end of the pressurizing piston 5 is provided with a spring spring 7, and the outer end is connected to a pressurizing button 8;

[0023] The outer end of the support piston 6 extends vertically upward and connects to the support claw 9;

[0024] The cylinder passage 4 is equipped with an oil circuit switch 10. Pressing the pressurization button 8 allows hydraulic oil to enter the second cylinder 3 and support the support claw 9. The cylinder passage 4 is then closed by the oil circuit switch 10 to lock the support.

[0025] The first hydraulic cylinder 2 and the second hydraulic cylinder 3 are arranged side by side in parallel, with the top extending through the hydraulic cylinder housing 1. The hydraulic cylinder passage 4 is placed laterally between the first hydraulic cylinder 2 and the second hydraulic cylinder 3. The hydraulic circuit switch 10 moves within the hydraulic cylinder passage 4 to close or open the hydraulic cylinder passage 4. The hydraulic circuit switch 10 passes through the hydraulic cylinder housing 1 and is connected to the hydraulic circuit release button 11 and the hydraulic circuit lock button 12 at its ends, respectively. The hydraulic cylinder passage 4 is closed or opened by pressing the hydraulic circuit release button 11 and the hydraulic circuit lock button 12.

[0026] Press the pressurization button 8 to push the pressurization piston 5 down, allowing the hydraulic oil from the first cylinder 2 to enter the second cylinder 3 through the cylinder passage 4, pushing the support piston 6 up so that the support claw 9 is in close contact with the product support surface. Press the oil circuit locking button 12 to push the oil circuit switch 10, closing the cylinder passage. The second cylinder 3 closes, and the support piston 6 no longer changes its support height, thus achieving the working state.

[0027] The support claw 9 is sleeved on the outer end of the support piston 6. It is a detachable and replaceable support claw of multiple models, which can be flexibly selected according to the support requirements.
