Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, and in particular to a flange pressure oil seal fixture that facilitates oil drainage. Background Technology

[0002] A servo hydraulic press is an energy-efficient and high-performance hydraulic device that uses a servo motor to drive the main drive oil pump. It is primarily used in industrial fields such as stamping, forging, press fitting, and straightening, covering industries including automotive, new energy, electronics, and home appliances. Its core structure includes a servo motor, hydraulic pump, ball screw, and closed-loop control system, achieving precise programming and remote control of pressure and speed through fully closed-loop digital control.

[0003] Hydraulic presses for pressing oil seals into flanges require a fixture for placing the flange. Since two oil seals are pressed into the flange, the process typically involves applying oil, pressing in the first oil seal, applying oil again, and pressing in the second oil seal. This multiple oiling processes, combined with the pressing pressure, inevitably result in excess oil flowing out and contaminating the work surface. Therefore, the purpose of this invention is to provide a fixture for pressing oil seals into flanges that allows for easy oil drainage. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a flange oil sealing fixture that is easy to drain oil. The fixture has a clever structural design, which facilitates the collection of excess oil during the flange oil sealing process and will not contaminate the workbench. In addition, the flange seat is easy to replace, which improves the versatility of the fixture.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a flange oil seal fixture that is easy to drain oil, the fixture including a base, a lower plate, a tooling seat, an oil collection box and a flange seat, the lower plate being installed on the upper surface of the base; the tooling seat being installed on the upper surface of the lower plate, and the flange seat being placed on the tooling seat;

[0006] The tooling base is shaped like a "∏". The tooling base includes two side plates and a top plate. The oil collection box is located directly below the top plate. The flange seat has a hollow central cavity in the middle position. The center of the lower surface of the flange seat extends downward to form a guide post. The top plate has a central hole in the middle that matches the guide post.

[0007] The upper surface of the flange seat is provided with multiple radially extending radial flow channels, and adjacent radial flow channels are connected by multiple arc-shaped flow channels; the upper surface of the top plate has a circumferential flow channel and multiple transverse flow channels, one end of the transverse flow channel is connected to the circumferential flow channel and the other end is connected to the central hole; the size of the flange seat is smaller than the size of the top plate.

[0008] Furthermore, the inner wall of the central cavity is provided with two axially extending first strip grooves.

[0009] Furthermore, the inner wall surface of the central hole also has multiple axially extending second strip grooves, and one end of the transverse flow channel is connected to the upper end of the second strip groove.

[0010] Furthermore, the upper end of the flange seat has a positioning boss that matches the hole in the flange.

[0011] Furthermore, the top plate, side plates, and bottom plate are secured together using the same fastener.

[0012] Furthermore, the base is provided with multiple inverted "T" shaped grooves, and the lower plate has opening grooves at the four corners. The lower plate is detachably fixed to the base by inserting bolts into the inverted "T" shaped grooves and using nuts.

[0013] The beneficial effects of this utility model are:

[0014] This utility model features an ingenious structural design. During the process of pressing the oil seal into the flange, oil is applied multiple times. Multiple radial and arc-shaped flow channels are set on the upper surface of the flange seat. The oil flows along the radial and arc-shaped flow channels to the outer circumferential surface of the flange seat, then flows to the top plate of the tooling seat, and flows along the circumferential and transverse flow channels on the top plate to the second groove. Finally, it drips into the oil collection box. The oil in the oil collection box can be emptied periodically. Therefore, through the above structural design, excess oil can be collected and reused without contaminating the workbench and keeping the working environment clean and tidy.

[0015] Furthermore, in order to press oil seals onto flanges of different specifications, the flange seats need to be replaceable. To improve the ease of flange seat replacement, this utility model does not lock and fix the flange seat to the tooling seat. Instead, the guide post of the flange seat is inserted into the center hole of the tooling seat for positioning and limiting, so as to facilitate the replacement of the flange seat.

[0016] Furthermore, the flange is also positioned on the flange seat by a positioning boss, and the two are not fixedly locked. When the upper pressure head used to hold the oil seal pushes the oil seal down, the central rod at the bottom of the upper pressure head will enter the central cavity of the flange seat. Air will enter during the downward pressing of the upper pressure head. Therefore, a first groove is set on the inner wall of the central cavity to prevent the upper pressure head from fitting too tightly with the central cavity, which would cause the flange seat to be lifted when the upper pressure head is lifted.

[0017] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] The following specific embodiments illustrate the detailed implementation of this utility model. Those skilled in the art can easily understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in this utility model.

[0026] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the accompanying drawings, have no special meaning, and are not intended to limit the scope of protection of this utility model.

[0027] Example: A flange pressure oil seal fixture for easy oil drainage, such as... Figures 1 to 5 As shown, the fixture 2 includes a base 21, a lower plate 22, a tooling seat 23, an oil collection box 24, and a flange seat 25. The lower plate is mounted on the upper surface of the base; the tooling seat is mounted on the upper surface of the lower plate; and the flange seat is placed on the tooling seat.

[0028] The tooling base is shaped like a "∏". The tooling base 23 includes two side plates 231 and a top plate 232. The oil collection box is located directly below the top plate. The flange seat has a hollow central cavity in the middle position. The lower surface of the flange seat extends downward to form a guide post 254. The top plate has a central hole 2321 that matches the guide post in the middle.

[0029] The upper surface of the flange seat is provided with multiple radially extending radial flow channels 251, and adjacent radial flow channels are connected by multiple arc-shaped flow channels 252; the upper surface of the top plate has a circumferential flow channel 2322 and multiple transverse flow channels 2323, one end of the transverse flow channel is connected to the circumferential flow channel and the other end is connected to the central hole; the size of the flange seat is smaller than the size of the top plate. This ensures that oil dripping from the outer circumference of the flange seat can be collected on the top plate and eventually flow into the oil collection box.

[0030] In this embodiment, the inner wall of the central cavity is provided with two axially extending first strip grooves 2541.

[0031] In this embodiment, the inner wall surface of the central hole also has a plurality of axially extending second strip grooves 23211, and one end of the transverse flow channel is connected to the upper end of the second strip groove.

[0032] In this embodiment, the upper end of the flange seat has a positioning boss 253 that matches the hole in the flange, facilitating the positioning of the flange during placement.

[0033] In this embodiment, the top plate, side plate, and bottom plate are fixed together using the same fastener.

[0034] In this embodiment, the base is provided with multiple inverted "T"-shaped grooves 211, and the lower plate has opening grooves 221 at its four corners. The lower plate is detachably fixed to the base by inserting bolts into the inverted "T"-shaped grooves and using nuts. This structure allows the position of the lower plate on the base plate to be adjusted left and right to meet more needs.

[0035] The working principle and process of this utility model:

[0036] Align the center hole of the flange with the positioning boss of the flange seat, then place the oil seal on the upper pressure head of the hydraulic press. The hydraulic drive device of the hydraulic press drives the upper pressure head to press down and press the oil seal onto the flange. The hydraulic drive device then drives the upper pressure head to lift up. Repeat the above process to press in another oil seal.

[0037] The above process involves multiple oiling processes. Multiple radial and arc-shaped flow channels are set on the upper surface of the flange seat. The oil will flow along the radial and arc-shaped flow channels to the outer circumferential surface of the flange seat, and then flow to the top plate of the tooling seat. It will then flow along the circumferential and transverse flow channels on the top plate to the second groove, and finally drip into the oil collection box. The oil in the oil collection box can be emptied periodically. Through the above structural design, excess oil can be collected and reused without contaminating the workbench and keeping the working environment clean and tidy.

[0038] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
