[0003] Therefore, there is an urgent need for a fuel injector gasket pressing mechanism that has high safety performance and can monitor the gasket pressing status in real time to ensure the press-fitting qualification rate. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a gasket pressing mechanism for a fuel injector, which solves the problem that the prior gasket pressing mechanism has poor safety performance and cannot ensure whether the gasket is fully pressed into place.

[0010] Optionally, the positioning push head is slidably connected to the pressing slide table, the sliding direction of the positioning push head is consistent with the sliding direction of the pressing slide table, and a buffer spring is arranged between the positioning push head and the pressing slide table.

[0011] Optionally, one end of the positioning push head towards the oil injector is provided with a rigid clamping piece capable of clamping the gasket.

DETAILED DESCRIPTION

[0021] The utility model will be explained in further detail in combination with the drawings and embodiments, these drawings are all simplified schematic diagram, only with schematic way the basic structure of the utility model is explained, therefore it shows only the structure related to the utility model.

[0022] It should be noted that if the embodiments involve directional indications (such as up, down, bottom, top, etc.), the directional indications are only used to explain the relative position relationship, movement, etc. between the components in a certain posture, and if the posture changes, the directional indications will also change accordingly. The terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features with "first" and "second" can explicitly or implicitly include one or more features. Unless otherwise specified and limited, the terms "set", "connected", "connected" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0023] As Figures 1-4 shown, a gasket press fitting mechanism for an oil injector includes a pressure mounting platform 1 and a positioning tool 3 for positioning the position of the oil injector, the positioning tool 3 is installed on the pressure mounting platform 1, a pressure mounting sliding table 2 capable of moving towards the positioning tool 3 is connected on the pressure mounting platform 1, and a positioning push head 4 capable of placing a gasket is arranged on one end of the pressure mounting sliding table 2 towards the oil injector. In the technical solution, the gasket is placed on the positioning push head 4, and can maintain the state of the opening facing the oil injector; the oil injector can be fixed on the pressure mounting platform 1 by the positioning tool 3, and at this time the position of the oil injector requiring installation of the gasket can correspond to the gasket on the positioning push head 4, and by moving the pressure mounting sliding table 2, the positioning push head 4 can accurately press fit the gasket on the oil injector.

[0024] Further, in order to avoid the gasket from being pressed into the position, the pressing sliding table 2 is provided with a sensing target block 5, and the pressing loading table 1 is provided with a sensor 6 corresponding to the sensing target block 5. The sensor 6 is a prior art, which can monitor the position information of the sensing target block 5 in real time. That is, the sensor 6 remains fixed in position, the sensing target block 5 can move synchronously with the pressing sliding table 2, and the sensor 6 can feedback the position of the pressing sliding table 2 by monitoring the displacement distance of the sensing target block 5 in real time, so as to determine whether the gasket is pressed into the position, thereby effectively improving the qualified rate of gasket pressing.

[0025] Further, in order to prevent the gasket pressing mechanism from being abnormally operated by the operator (non-operator) when there is no corresponding production task, the pressing loading table 1 is provided with a first lifting cylinder 7 and a second lifting cylinder 8 electrically connected with the sensor 6, and the pressing sliding table 2 is provided with a first limiting groove 201 and a second limiting groove 202 corresponding to the output ends of the first lifting cylinder 7 and the second lifting cylinder 8 respectively. In the technical solution, the output end of the first lifting cylinder 7 can be vertically embedded into the first limiting groove 201, and the output end of the second lifting cylinder 8 can be vertically embedded into the second limiting groove 202, and the output end of the second lifting cylinder 8 can slide relatively in the second limiting groove 202. That is, when there is no corresponding production task, after the pressing sliding table 2 moves away from the positioning tool 3, the output end of the first lifting cylinder 7 can be embedded into the first limiting groove 201 on the pressing sliding table 2, thereby limiting the sliding of the pressing sliding table 2 and improving the safety of the pressing mechanism.

[0026] When the production task is performed, the output end of the first lifting cylinder 7 can be retracted from the first limiting groove 201, and after the oil sprayer is placed on the positioning tool 3, the output end of the second lifting cylinder 8 can be embedded into the second limiting groove 202 after the pressing sliding table 2 moves to a certain distance away from the positioning tool 3. The second limiting groove 202 is in a meandering shape, and the output end of the second lifting cylinder 8 can slide a certain distance in the second limiting groove 202. That is, in the technical solution, the sensor 6 can monitor whether the output end of the first lifting cylinder 7 corresponds to the first limiting groove 201 and whether the output end of the second lifting cylinder 8 corresponds to the second limiting groove 202. When the production task is performed, if the sensor 6 feedbacks that the position of the second limiting groove 202 on the pressing sliding table 2 corresponds to the output end of the second lifting cylinder 8, the output end of the second lifting cylinder 8 will be embedded into the second limiting groove 202. Subsequently, the pressing sliding table 2 can continue to move towards the oil sprayer, and when the sensor 6 monitors that the pressing sliding table 2 does not reach the position, it resets, that is, when the gasket is not completely pressed in, the output end of the second lifting cylinder 8 will still be embedded into the second limiting groove 202, thereby prohibiting the pressing sliding table 2 from returning. Until the gasket is completely pressed in, the output end of the second lifting cylinder 8 will be retracted from the second limiting groove 202, and the pressing sliding table 2 can move away from the positioning tool 3, waiting for the next operation.

[0027] Further, as shown in Figure 1 , Figure 4 , the positioning tool 3 includes a flange positioning seat 301 detachably connected to the press mounting table 1, and the flange positioning seat 301 is provided with a profiling positioning groove 3011 capable of being embedded in the oil sprayer. The profiling positioning groove 3011 on the flange positioning seat 301 can closely fit the shape of the oil sprayer, so that the oil sprayer can be quickly determined in the accurate transverse and longitudinal position when placed in the positioning tool 3, limiting the displacement freedom of the oil sprayer in the plane, and improving the positioning accuracy. At the same time, the press mounting table 2 is provided with a supporting back plate 9, one end of the supporting back plate 9 can correspond to the position height of the gasket, and the end of the supporting back plate 9 can abut and be clamped on the outer periphery of the oil sprayer. The supporting back plate 9 can form a three-dimensional positioning system with the profiling positioning groove 3011. The profiling positioning groove 3011 mainly controls the bottom plane position and part of the radial position of the oil sprayer, while the supporting back plate 9 further constrains the oil sprayer from the side of the outer periphery of the oil sprayer, which can effectively prevent the oil sprayer from rotating or tilting in the direction perpendicular to the bottom surface, ensuring the position stability of the oil sprayer in the three-dimensional space, and improving the stability and accuracy of the gasket pressing. At the same time, the supporting back plate 9 can provide stable support for the position of the oil sprayer, prevent the positioning tool 3 from shifting or shaking due to the press force, and ensure that the gasket can be accurately pressed into the predetermined position, improving the precision and quality stability of the pressing.

[0028] The flange positioning seat 301 is detachably mounted, which can be installed and removed by bolts and other fasteners, so that the operator can replace different types of flange positioning seats 301 to meet the production needs of different types of oil sprayers, and improve the universality and applicability of the pressing mechanism.

[0029] Further, as shown in Figure 1 , the positioning push head 4 is slidingly connected to the press mounting table 2, and the sliding direction of the positioning push head 4 is consistent with the sliding direction of the press mounting table 2, and a buffer spring 10 is arranged between the positioning push head 4 and the press mounting table 2. The buffer spring 10 can play a key buffering role in the pressing process. That is, when the positioning push head 4 and the gasket contact the oil sprayer, the spring can absorb part of the impact force, avoiding damage to the oil sprayer, the gasket and the positioning push head 4 itself caused by rigid collision.

[0030] In the embodiment, the positioning push head 4 is provided with a rigid clamp 401 capable of clamping the gasket at one end of the oil injector. The rigid clamp 401 can stably clamp the gasket, facilitate the taking and placing of the gasket, and prevent the gasket from being displaced, falling or turned over due to vibration, shaking or other external force interference during the movement of the press fitting sliding table 2 and the positioning push head 4. The gasket can always maintain an accurate posture and position during the entire process of being press fitted onto the oil injector, greatly improving the accuracy and consistency of the gasket press fitting, and effectively reducing the product assembly problems caused by the position deviation of the gasket. The press fitting sliding table 2 and the press fitting loading table 1 and the positioning push head 4 and the press fitting sliding table 2 are connected through linear guide rail sliding to increase the accuracy of the linear movement of the press fitting sliding table 2 and the positioning push head 4.

[0031] As shown in Figure 1 , Figure 2 In the technical solution, the press fitting loading table 1 is provided with a hand push elbow clamp 11 capable of driving the press fitting sliding table 2 to move towards the positioning tool 3. The hand push elbow clamp 11 is a kind of quick clamp in the prior art, which is convenient, simple and effective. Under the use of the operator, the press fitting sliding table 2 can be quickly and stably driven to move towards the positioning tool 3.

[0032] Working principle: during operation, the oil injector is placed in the profiling positioning groove 3011, and the supporting rest plate 9 is clamped and abuts against the oil injector. Then the gasket is placed in the rigid clamp 401 of the positioning push head 4. Then the output end of the first lifting cylinder 7 is retracted from the first limiting groove 201, the press fitting sliding table 2 is driven by the hand push elbow clamp 11 to move close to the positioning tool 3 to a certain distance, and the output end of the second lifting cylinder 8 can be embedded in the second limiting groove 202. Since the output end of the second lifting cylinder 8 can slide a certain distance in the second limiting groove 202, and the sensor 6 can feedback whether the press fitting sliding table 2 is completely in place, i.e. the gasket is not completely pressed in, the press fitting sliding table 2 can be inhibited from returning under the interaction of the second lifting cylinder 8 and the second limiting groove 202. Until the gasket is completely pressed in, the output end of the second lifting cylinder 8 can be retracted from the second limiting groove 202, and the press fitting sliding table 2 can move away from the positioning tool 3, waiting for the next operation, thereby effectively improving the qualified rate of the gasket being pressed into the oil injector. When there is no corresponding production task, the output end of the first lifting cylinder 7 can be embedded in the first limiting groove 201 after the press fitting sliding table 2 moves away from the positioning tool 3, thereby locking the position of the press fitting sliding table 2, preventing the mechanism from being misoperated, and effectively ensuring the safety of the press fitting mechanism.

[0033] Based on the ideal embodiment of the present application, the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of the claims.
