Abstract
Description
Technical Field
[0001] This invention relates to the field of refrigeration unit assembly, and more specifically to a horizontal oil separator assembly platform. Background Technology
[0002] The horizontal oil separator, a key component in screw compressors, is undeniably crucial. Both the compressor and motor are mounted on it, along with flanges for connecting piping. Due to the non-standard nature of horizontal oil separators, it's typically necessary to match the appropriate motor and compressor based on actual site conditions, while simultaneously adjusting the flange position. In the production and assembly of refrigeration units, the assembly accuracy of the horizontal oil separator directly affects the overall performance and operational reliability of the unit. Currently, traditional assembly methods rely heavily on simple tooling or general-purpose platforms for support and positioning, lacking dedicated positioning devices. This makes it difficult to ensure the accuracy of core assembly dimensions such as coaxiality and perpendicularity between the cylinder and various components, leading to deviations in subsequent welding or connection processes and impacting product quality. If a custom positioning platform is customized each time specifications are changed, tooling needs to be readjusted or replaced every time the product model is changed, undoubtedly increasing production preparation time and costs. These issues limit the improvement of horizontal oil separator assembly quality and production efficiency. Therefore, there is an urgent need for a horizontal oil separator assembly platform that is structurally sound, precisely positioned, highly versatile, and easy to operate to overcome the aforementioned technical deficiencies. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a horizontal oil separator assembly platform with strong versatility, high positioning accuracy and firm positioning.
[0004] The specific technical solution of the present invention to solve the above-mentioned technical problems is as follows:
[0005] A horizontal oil separator assembly platform includes a support platform, and further includes a compressor support positioning module, a flange support positioning module, and a motor support positioning module disposed on the support platform. Two main guide rails are arranged parallel to each other on the support platform, and the compressor support positioning module, flange support positioning module, and motor support positioning module are slidably disposed on the two main guide rails. Each compressor support positioning module, flange support positioning module, and motor support positioning module includes a sub-guide rail perpendicular to the main guide rail and at least one slider disposed on the sub-guide rail. The slider is provided with a positioning and clamping pin, which is used to position and clamp the compressor support, motor support, and flange to be assembled.
[0006] Compared with the prior art, this invention has the following beneficial effects: By setting compressor support positioning modules, flange support positioning modules, and motor support positioning modules that can slide along the main guide rail on the support platform, the position of each module in the direction of the main guide rail can be flexibly adjusted according to the size requirements of different models of horizontal oil separators, thereby adapting to the assembly needs of various product specifications, greatly enhancing the versatility of the platform, avoiding the trouble of frequently changing or adjusting special tooling in the traditional method, and effectively reducing production preparation time and costs. At the same time, each positioning module is equipped with a sub-guide rail perpendicular to the main guide rail and a slider that can slide on the sub-guide rail. The positioning and clamping pins on the slider can accurately position and firmly clamp the compressor support, motor support, and flange from the direction perpendicular to the main guide rail. This design not only allows for fine-tuning of the positions of each component in the direction of the sub-guide rail to meet different assembly position requirements, but also ensures the positional accuracy of the components to be assembled in two directions through the synergistic effect of the positioning and clamping pins. This effectively guarantees the core assembly dimensions such as coaxiality and perpendicularity between the cylinder of the horizontal oil separator and each component, thereby improving the quality stability of subsequent welding or connection processes and enhancing the performance and operational reliability of the entire refrigeration unit.
[0007] Furthermore, the slider is provided with a master pin hole, and the positioning clamping pin includes a master pin body. The master pin body has a notch extending through the diameter direction. A clamping rod and a rack are provided in the notch. The clamping rod is rotatably disposed in the notch. The clamping rod includes a connecting end and a clamping end. The connecting end is an incomplete gear with teeth on its surface. The rack meshes with the teeth and can move up and down. The lower end of the rack is connected to a lifting drive structure.
[0008] The beneficial effect of adopting the above-mentioned further solution is that by setting a master pin hole on the slider and designing the positioning and clamping pin as a combination of the master pin body, the clamping rod, rack, and lifting drive structure within the notch, the positioning and clamping functions are integrated and automated. The master pin body can be inserted into the positioning hole of the component to be assembled (such as a compressor support, motor support, or flange) to play a preliminary radial positioning role, ensuring that the component will not shift on the horizontal plane. When the lifting drive structure drives the rack to move up and down, the rack meshes with the teeth of the connecting end (incomplete gear) of the clamping rod, causing the clamping rod to rotate around its rotation axis within the notch. When the rack rises, the incomplete gear rotates clockwise, causing the clamping end of the clamping rod to rotate out of the notch and press downward against the surface of the component to be assembled; when the rack descends, the incomplete gear rotates counterclockwise, and the clamping end retracts upward into the notch, releasing the clamping force on the component. This structural design cleverly utilizes the precision of gear and rack transmission to ensure the stability and positional accuracy of the clamping rod's movement. It provides reliable axial clamping force, effectively preventing displacement of components during assembly or welding due to vibration or external forces. Furthermore, housing the clamping rod within the notch of the main pin notch not only avoids interference with component loading and unloading but also protects the clamping rod structure from external impact damage, extending the device's service life.
[0009] Furthermore, the lifting drive structure is one of the following: a linkage structure, a cylinder, or a linear motor.
[0010] The advantages of adopting the above-mentioned further solutions are as follows: When using a linkage structure as the lifting drive structure, the rack and pinion can be smoothly lifted and lowered through the lever principle or multi-link combination. It has the characteristics of simple structure, low cost, and convenient maintenance, and is suitable for occasions where the requirements for driving force and movement speed are not high. When using a cylinder as the lifting drive structure, it can use compressed air to provide a large driving force, with rapid action response, easy to realize automated control, and good overload protection performance, making it suitable for large-volume, high-efficiency assembly operations on the production line. When using a linear motor as the lifting drive structure, electrical energy can be directly converted into linear motion, eliminating the intermediate transmission mechanism. It has advantages such as high positioning accuracy, fast movement speed, and good dynamic response, and can meet the precision assembly scenarios with extremely high assembly accuracy requirements. It can be flexibly selected according to different actual production needs.
[0011] Furthermore, the slider is also provided with an auxiliary pin hole, and the lifting drive structure includes a first connecting rod, a second connecting rod, a base, an auxiliary pin body, a push rod, a lever, a drive component, a release spring, and a return spring;
[0012] The lower end of the rack is hinged to a first connecting rod, the other end of the first connecting rod is hinged to a second connecting rod, and the other end of the second connecting rod is hinged to a base. A first limiting part is provided on the base. One end of the release spring abuts against the first limiting part, and the other end abuts against the hinge joint of the first and second connecting rods. The hinge shaft of the first and second connecting rods extends axially to form a push shaft. The auxiliary pin is movably disposed within the auxiliary pin hole. A push rod is hinged to the auxiliary pin. The free end of the push rod has a pushing part and a turning part. When the auxiliary pin is in a free state, the hinged end of the push rod is higher than the free end, and the pushing part abuts against the surface of the push shaft due to its own weight. The pushing part is used to push the push shaft to move horizontally; when the upper end face of the auxiliary pin body is level with the upper surface of the slider, the push rod is in a horizontal state, and the rack, the first connecting rod and the second connecting rod are in a collinear state; the pawl is hinged to the base, the pawl includes a pawl end, the driving member is used to drive the pawl to rotate around the hinge axis, and to make the pawl end push the pawl part upward, so that the push rod disengages from the push shaft, and then the first connecting rod and the second connecting rod get rid of the collinear state under the action of the release spring, driving the rack to move downward; and then driving the clamping rod to retract into the main pin body; the return spring is located below the auxiliary pin body, and is used to drive the auxiliary pin body to return to its original position.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the lifting drive structure, through ingenious mechanical linkage design, realizes the automated triggering and release of positioning and clamping actions, significantly improving the convenience and reliability of assembly operations. When the component to be assembled (such as a compressor support, motor support, or flange) is placed on the slider, since the height of the main pin is greater than the height of the auxiliary pin, the main pin first inserts into the positioning hole on the component. Subsequently, the bottom surface of the component contacts and presses down on the auxiliary pin, forcing the auxiliary pin to move downward along the auxiliary pin hole. During this process, the push rod, which was originally higher than the free end due to its own weight, gradually tends to be horizontal. Its pushing part, while descending with the auxiliary pin, will generate a horizontal thrust on the push shaft, causing the hinge of the first link and the second link to overcome the elastic force of the release spring and move horizontally. When the component is fully placed in place, and the upper end face of the auxiliary pin is level with the upper surface of the slider, the push rod is exactly in a horizontal state. At this time, the first link, the second link, and the rack are also exactly in a collinear state (i.e., a dead point position). In this collinear state, the linkage mechanism exhibits extremely high structural stability, effectively maintaining the rack in the upper position where the clamping rod presses against the component, ensuring continuous and reliable clamping force, and effectively preventing loosening of the component during assembly. When it is necessary to release the component, the drive unit drives the lever to rotate, and the lever's actuating end pushes the push rod's actuating part upward, causing the push rod's free end to rise and disengage from the push shaft. At this time, the hinge between the first and second links loses the constraint of the push rod and quickly resets under the elastic force of the release spring, breaking the collinear dead point state. This causes the first and second links to fold, which in turn drives the rack to move rapidly downward. The rack, through gear meshing, drives the clamping rod to rotate upward and retract into the notch of the main pin, releasing the clamping force on the component. After the welded and assembled product is removed, the pressed auxiliary pin resets upward under the action of the return spring, and the push rod also returns to its initial tilted state, awaiting the next assembly cycle. This purely mechanical linkage design achieves self-locking by utilizing the weight of the components to be assembled. The heavier the component, the greater the clamping force. Automatic clamping and release can be achieved without complex sensors and control systems. It is fast-responding, reliable in action, compact in structure, and easy to maintain, which greatly improves the assembly efficiency and operational safety of horizontal oil separators.
[0014] Furthermore, the clamping end of the clamping rod is elastic.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the clamping end of the clamping rod is made of an elastic material (such as spring steel sheet), or has a spring structure embedded in the clamping end. When the clamping rod presses down on the part to be assembled, the elastic end can adapt to the slight unevenness of the part surface or the difference in the thickness of the part itself through its own deformation, avoiding the situation where the part cannot be completely flat due to rigid connection, and ensuring the stability of clamping and the stability of part placement. In addition, the elastic end can also compensate to a certain extent for the fluctuation of clamping force caused by part processing errors or assembly gaps, so that the clamping force is applied to the part more evenly and gently, further improving the reliability of positioning clamping and the applicability to parts of different materials.
[0016] Furthermore, the lever is also provided with a second limiting part, the push rod is in a horizontal state, and the push shaft abuts against the second limiting part.
[0017] The beneficial effect of adopting the above-mentioned further solution is that, by setting a second limiting part on the lever, when the push rod pushes the push shaft to the dead point position where the first link, the second link, and the rack are collinear under the action of the gravity of the assembled workpiece, the push shaft at the hinge of the first link and the second link precisely abuts against the second limiting part. The setting of the second limiting part provides a precise mechanical stop for the collinear state of the linkage mechanism, which can effectively limit the excessive displacement of the hinge of the first link and the second link due to inertia or the impact force when the parts are placed, ensuring that the linkage mechanism stays stably and reliably at the collinear dead point position, avoiding insufficient clamping force or instability caused by position deviation. At the same time, the second limiting part can also share part of the force borne by the release spring during the assembly process, preventing the spring from fatigue failure due to long-term overload, extending the overall service life of the lifting drive structure, and further improving the structural stability and operational reliability of the entire assembly platform.
[0018] Furthermore, the driving component is one of an electromagnet, a cylinder, a cam, or a linear motor.
[0019] The advantage of adopting the above-mentioned further solution is that the appropriate drive method can be flexibly selected according to the actual production conditions and assembly accuracy requirements. Attached Figure Description
