Description

Technical Field

[0001] This utility model relates to the field of oil storage tank technology, specifically to a compressor oil storage tank that can be quickly installed. Background Technology

[0002] A press is a forming machine used to shape industrial products by pressure. It generally uses hydraulic cylinders, hence the name hydraulic press. The oil reservoir holds the hydraulic fluid required by the hydraulic system, ensuring sufficient oil supply to the pump and actuators (such as hydraulic cylinders) during circulation. After circulating through the system, the oil returns to the reservoir, forming a closed loop.

[0003] Currently, the oil storage tank is mainly fixed to the press by locking parts such as bolts and nuts. When the oil storage tank needs to be maintained regularly, that is, when the inside of the oil storage tank needs to be cleaned, the bolts need to be turned many times to remove the oil storage tank from the press or reinstall it on the press. Therefore, there is some inconvenience in disassembling and assembling the oil storage tank.

[0004] In addition, the oil reservoir and the pump body (e.g., a manual pump) are fixed by threads. That is, corresponding threaded holes are made on the connecting plate of the pump body and the oil reservoir, and fixing nuts corresponding to the threaded holes are installed on the inner wall of the oil reservoir. The oil reservoir and the pump body can be fixed by screwing the bolt into the fixing nuts.

[0005] However, when installing the fixing nut, it is impossible to ensure that the fixing nut and the threaded hole are concentric, which can easily lead to stripping of the threads when the bolt is screwed into the fixing nut, thus affecting the stability of the connection between the oil reservoir and the pump body. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a press oil storage tank that can be installed quickly, which can facilitate the disassembly and assembly of the oil storage tank while improving the stability of the connection between the oil storage tank and the pump body.

[0010] The present invention is further configured such that: a spring is fitted around the outer periphery of the limiting rod, and the spring is used to drive the limiting rod to reset so that the limiting rod extends again.

[0011] The present invention is further configured such that: the outer wall of the box is provided with a connecting ear, the connecting ear includes an outwardly extending extension, and an abutting part is fixed on the extension, the abutting part being flush with the surface of the slider.

[0012] The present invention is further configured such that: the outer periphery of the fixing nut is provided with knurled teeth, the knurled teeth are multiple and evenly distributed around the circumference, and the fixing nut is plastically deformed around the countersunk hole by extrusion, so as to fix the fixing nut to the guide countersunk hole.

[0013] The present invention is further configured such that: the outer periphery of the fixing nut is provided with knurled teeth, the knurled teeth are multiple and evenly distributed around the circumference, and the fixing nut is plastically deformed around the countersunk hole by extrusion, so as to fix the fixing nut to the guide countersunk hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By using a quick-release device on the outside of the tank, the tank can be quickly installed on or removed from the press, which facilitates regular maintenance of the oil storage tank and solves the technical problem of the cumbersome disassembly and assembly of the oil storage tank in the prior art.

[0016] Furthermore, by setting a guide countersunk hole concentric with the threaded hole on the inner wall of the housing, and by matching the guide countersunk hole with the fixing nut, the positioning of the fixing nut by the guide countersunk hole during installation can ensure that the fixing nut is concentric with the threaded hole after installation. Therefore, this effectively solves the technical problem in the prior art where the fixing nut and the threaded hole are prone to deviation during installation, thereby ensuring that the fixing nut and the threaded hole are concentric, preventing stripping, and improving the stability of the connection between the oil reservoir and the press.

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] like Figures 1 to 7 As shown, this utility model discloses a press oil storage tank that can be quickly installed, including a tank body 1, an oil storage chamber 101 inside the tank body 1, an oil outlet 2 communicating with the oil storage chamber 101 on the top of the tank body 1, and a quick-release device on the outside of the tank body 1. The tank body 1 is connected to the press through the quick-release device, so that the tank body 1 can be quickly installed on or removed from the press, which facilitates regular maintenance of the oil storage tank.

[0027] Specifically, the quick-release device includes a slide rail 61, which can be fixed to the outer wall of the press by welding. A slider 62 is coupled on the slide rail 61. A guide groove 612 is provided on the outer side of the slide rail 61. A guide block 623 is provided on the slider 62 opposite to the slide groove. In this way, the guide block 623 can be pressed into the guide groove 612, so that the guide block 623 can slide along the direction of the guide groove 612, thereby forming a sliding fit between the slider 62 and the slide rail 61. The slider 62 is connected to the housing 1 on the side facing away from the slide rail 61. A retractable limiting rod 63 is provided on one side of the slider 62. A limiting groove 611 is provided on the inner side of the slide rail 61. There are multiple limiting grooves 611, which are spaced apart from each other. The limiting rod 63 can be inserted into or detached from the limiting groove 611 by extending or retracting to approach or move away from the slide rail 61. Therefore, after the limiting rod 63 is inserted into the limiting groove 611, the slider 62 can be fixed. After the limiting rod 63 is detached from the limiting groove 611, the slider 62 can be slid until it slides out from one end of the slide rail 61. Then the oil tank connected to the slider 62 can be removed.

[0028] The structure for extending and retracting the limiting rod 63 is as follows: a cavity 621 is provided inside the slider 62, and a retractable drive rod 64 is provided on one side of the slider 62. One end of the drive rod 64 can extend into the cavity 621 as a drive end, and a push rod 65 is fixed to this drive end. The slider 62 is provided with a guide groove 622 communicating with the cavity 621. The limiting rod 63 can be placed in the guide groove 622 and slide along the guide groove 622 to ensure the extension and retraction path of the limiting rod 63. One end of the limiting rod 63 extends into the cavity 621 as a connection. At one end, a transmission block 66 is fixed to the connecting end. The transmission block 66 is provided with an obliquely arranged transmission groove 661. The push rod 65 is coupled to the transmission groove 661. When the push rod 65 is driven towards the slider 62 through the obliquely arranged transmission groove 661, the push rod 65 coupled to the transmission groove 661 can push the transmission block 66 to move along the path of the transmission groove 661. In this way, the axial force acting on the drive rod 64 can be converted into the axial force acting on the limiting rod 63, so as to drive the limiting rod 63 away from the limiting groove 611.

[0029] Furthermore, after the push rod 65 is released, the spring 67 sleeved on the outer periphery of the limiting rod 63, that is, the spring 67 embedded in the guide groove 622, can drive the limiting rod 63 to reset through the force generated by the compression, so that the limiting rod 63 can be extended again, thereby allowing the limiting rod 63 to be reinserted into the limiting groove 611, thus fixing the slider 62.

[0030] like Figure 3 As shown, a connecting ear 7 is further provided on the outer wall of the housing 1. The connecting ear 7 is used to fix the housing 1 to the slider 62. The connecting ear 7 includes an outwardly extending extension 71. After the housing 1 is fixed to the slider 62, the extension 71 can increase the distance between the housing 1 and the slider 62, so as to facilitate the user's hand to reach in and drive the push rod 65. An abutment 72 is fixed on the extension 71. The abutment 72 is flush with the surface of the slider 62, so that the abutment 72 can fully contact the slider 62 to ensure the stability of the housing 1 when it is fixed to the slider 62 by the connecting ear 7.

[0031] The outer periphery of the oil outlet 2 is provided with multiple threaded holes 3 for connecting with the connecting plate of the pump body. The inner wall of the top of the housing 1 is provided with a guide countersunk hole 4, which is concentric with the threaded holes 3. A fixing nut 5 is provided in the guide countersunk hole 4, and the fixing nut 5 is adapted to the guide countersunk hole 4. Therefore, when installing the fixing nut 5, the positioning of the fixing nut 5 by the guide countersunk hole 4 can ensure that the fixing nut 5 is concentric with the threaded hole 3 after installation. This ensures that the fixing nut 5 and the threaded hole 3 are concentric and prevents the connecting hole on the pump body connecting seat from merging with the threaded hole 3. During the alignment and screwing in of the bolts, slippage occurs, which improves the stability of the connection between the oil reservoir and the pump body. In addition, since the guide countersunk hole 4 and the threaded hole 3 are concentrically set, only two stampings are needed on the housing 1 to form the hole for machining the threaded hole 3 and the guide countersunk hole 4. This makes it more convenient to ensure that the fixing nut 5 and the threaded hole 3 are concentric and reduces the processing cost. After the connection between the oil reservoir and the pump body is made, one end of the hose can be connected to the oil outlet pipe and the other end can be connected to the oil inlet of the actuator to realize the connection between the oil reservoir and the actuator.

[0032] The outer periphery of the fixing nut 5 is further provided with knurled teeth 51. There are multiple knurled teeth 51 and they are evenly distributed around the circumference. Therefore, when the fixing nut 5 is installed in the guide countersunk hole 4, by pressing down the fixing nut 5, the knurled teeth 51 are pressed against the periphery of the guide countersunk hole 4 and undergo plastic deformation, so as to fix the fixing nut 5 in the guide countersunk hole 4. The diameter of the guide countersunk hole 4 is slightly smaller than the knurled teeth 51, so as to ensure that the guide countersunk hole 4 is compatible with the fixing nut.

[0033] In addition, in order to further improve the stability of the connection between the fixing nut 5 and the guide countersunk hole 4, the junction of the fixing nut 5 and the guide countersunk hole 4 is welded to form a weld point. Multiple welds are made to form multiple weld points that are evenly distributed around the circumference to form a weld line, thereby further improving the stability of the connection between the fixing nut 5 and the guide countersunk hole 4.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
