Description

Technical Field

[0001] This utility model belongs to the field of diaphragm compressor technology, and in particular relates to an auxiliary assembly device for the cylinder head of a diaphragm compressor. Background Technology

[0002] A diaphragm compressor is a positive displacement compressor that uses the reciprocating motion of a flexible diaphragm within a cylinder to achieve gas intake, compression, and discharge. It is widely used in industrial applications where high gas purity or oil-free compression is required, such as chemical, petroleum, natural gas, pharmaceutical, and new energy fields. Its core working principle is to use hydraulic or mechanical drive to cause the diaphragm, made of metal or non-metal, to undergo periodic deformation within the cylinder, thereby changing the cylinder volume and completing the gas intake and compression process.

[0003] The existing diaphragm compressor assembly process lacks an auxiliary assembly device capable of securing cylinder heads of different sizes and lifting them to the required height. The problems with this technology are: Currently, the assembly process of diaphragm compressors lacks an auxiliary assembly device that can adapt to cylinder heads of different sizes and achieve stable clamping and positioning. Due to the diverse specifications and complex structure of cylinder heads, traditional assembly methods often rely on manual operation or general tooling, making it difficult to achieve rapid clamping and reliable support of the cylinder heads. This easily leads to low assembly efficiency, poor positioning accuracy, and high labor intensity. Furthermore, existing devices also have significant shortcomings in cylinder head lifting, lacking an adjustable height and angle fine-tuning mechanism. This makes it difficult to accurately match the cylinder head to the installation position during docking, affecting assembly quality and work efficiency. In addition, the lack of a flexible clamping design can easily damage the cylinder head surface during clamping, reducing assembly safety. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a cylinder head auxiliary assembly device for a diaphragm compressor that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: A cylinder head auxiliary assembly device for a diaphragm compressor includes a mounting base, a hydraulic pump, and a lifting rod. The surface of the mounting base is fixedly connected to the surface of the hydraulic pump. A label on the mounting base is fixedly connected to the lower surface of the lifting rod. A fixing device is provided at the upper end of the lifting rod, and an adjustment device is provided at the lower side of the fixing device. The fixing device is used to clamp and fix the cylinder head; The adjustment device is used to adjust the overall angle of the fixing device during installation.

[0006] To improve the adaptability of the equipment, preferably, the fixing device includes a servo motor, a transmission screw, a connecting plate, a mounting plate, a clamping plate, a bearing plate, and a guide groove. The output end of the servo motor is fixedly connected to the left end of the transmission screw. The surface of the transmission screw is threadedly connected to the inner walls of the two connecting plates. The upper inner wall of the connecting plate is fixedly connected to the lower surface of the mounting plate. The inner wall of the mounting plate is fixedly connected to the surface of the clamping plate. The guide groove is formed on the inner wall of the bearing plate. Since the threads at both ends of the transmission screw rotate in opposite directions, the two connecting plates can be driven to move towards or away from each other in the guide groove on the bearing plate, effectively achieving flexible adaptation to cylinder heads of different sizes.

[0007] To improve the flexibility of angle adjustment, preferably, the adjustment device includes a fixed plate, a mating plate, a hydraulic cylinder, and a support plate. The inner wall of the fixed plate is rotatably connected to the inner wall of the mating plate via a rotating shaft. The two ends of the hydraulic cylinder are rotatably connected to the inner wall of the support plate via a rotating shaft, so that the hydraulic cylinder can drive the support plate to produce an angle change during the extension and retraction process, and further transmit it to the bearing plate, thereby realizing flexible adjustment of the overall tilt angle of the bearing plate.

[0008] To improve the stability of the transmission screw rotation process, preferably, a bearing bracket is provided on the inner wall of the middle part of the bearing plate. The surface of the bearing bracket is fixedly connected to the inner wall of the bearing plate. The bearing bracket can provide reliable rotational support for the transmission screw, ensuring its coaxiality and stability during operation and reducing motion deviation caused by eccentricity or vibration.

[0009] To improve the smoothness of the connecting plate movement, preferably, the surface of the servo motor is fixedly connected to the left side surface of the bearing plate, the two ends of the transmission screw are rotatably connected to the inner wall of the bearing plate, the surface of the connecting plate is slidably connected to the inner wall of the guide groove, and the lower surface of the mounting plate is slidably connected to the upper surface of the bearing plate. The guide groove provides guidance for the movement of the connecting plate, preventing it from deviating or getting stuck during movement, ensuring the synchronization and reliability of the clamping action, and thus allowing the clamping plate to be adjusted according to the cylinder head size.

[0010] To improve the safety of the device, preferably, the upper end of the lifting rod is fixedly connected to the lower surface of the fixed plate, the lower end of the bearing plate is fixedly connected to the upper surface of the mating plate, and both sides of the upper end of the lifting rod and both sides of the lower end of the mating plate are fixedly connected to the surface of the support plate. The bearing plate always maintains synchronous movement during lifting or angle adjustment, thereby preventing instability during lifting or clamping.

[0011] To improve the reliability of the device, preferably, the middle surface of the transmission screw is rotatably connected to the inner wall of the bearing bracket. The bearing bracket can improve the coaxiality and running stability of the transmission screw during rotation, reduce transmission errors caused by eccentricity or bending, and thus improve the action accuracy of the fixing device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting up a fixing device, an adjusting device, a transmission screw, a connecting plate, a mounting plate, a clamping plate, a fixing plate, a mating plate, a hydraulic cylinder, and a support plate, uses a fixing device to clamp and fix the cylinder head, and an adjusting device to adjust the overall angle of the fixing device during installation. Since the threads at both ends of the transmission screw rotate in opposite directions, it can drive the two connecting plates to move towards or away from each other in the guide groove on the support plate, effectively realizing flexible adaptation to cylinder heads of different sizes. This allows the hydraulic cylinder to drive the support plate to change angle during extension and retraction, and further transmit this change to the support plate, realizing flexible adjustment of the overall tilt angle of the support plate. This solves the problem that the current diaphragm compressor assembly lacks stable clamping and positioning equipment that can adapt to various cylinder head sizes. Traditional methods rely on manual labor or general tooling, resulting in low assembly efficiency, poor positioning accuracy, and high labor intensity. Existing devices are insufficient in cylinder head lifting, lacking a lifting mechanism with adjustable height and angle fine-tuning functions, which affects assembly quality and efficiency. At the same time, the lack of flexible clamping design makes it easy to damage the cylinder head surface and reduce assembly safety. Attached Figure Description

[0016] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figures 1 to 4As shown in the figure, an auxiliary assembly device for the cylinder head of a diaphragm compressor provided by this utility model includes a mounting base 4, a hydraulic pump 5, and a lifting rod 6. The surface of the mounting base 4 is fixedly connected to the surface of the hydraulic pump 5. A label on the mounting base 4 is fixedly connected to the lower surface of the lifting rod 6. A fixing device 1 is provided at the upper end of the lifting rod 6, and an adjusting device 2 is provided at the lower side of the fixing device 1. The fixing device 1 is used to clamp and fix the cylinder head, and the adjusting device 2 is used to adjust the overall angle of the fixing device 1 during installation. The fixing device 1 includes a servo motor 101, a transmission screw 102, a connecting plate 103, a mounting plate 104, a clamping plate 105, a bearing plate 106, and a guide groove 107. The output end of the servo motor 101 is fixedly connected to the left end of the transmission screw 102. The transmission screw 102 is threadedly connected to the inner walls of two connecting plates 103. The upper inner wall of the connecting plate 103 is fixedly connected to the lower surface of the mounting plate 104. The inner wall of the mounting plate 104 is fixedly connected to the surface of the clamping plate 105. The guide groove 107 is formed on the inner wall of the bearing plate 106. Since the threads at both ends of the transmission screw 102 rotate in opposite directions, it can drive the two connecting plates 103 to move towards or away from each other in the guide groove 107 on the bearing plate 106, effectively realizing flexible adaptation to cylinder heads of different sizes. The adjusting device 2 includes a fixed plate 201, a mating plate 202, a hydraulic cylinder 203, and a support plate 204. The inner wall of the fixed plate 201 is rotatably connected to the inner wall of the mating plate 202 through a rotating shaft. The two ends of the hydraulic cylinder 203 are connected to the inner wall of the support plate 204 through a rotating shaft. The shaft rotation connection allows the hydraulic cylinder 203 to drive the support plate 204 to change angle during extension and retraction, which is then transmitted to the bearing plate 106, enabling flexible adjustment of the overall tilt angle of the bearing plate 106. A bearing bracket 3 is provided on the inner wall of the middle section of the bearing plate 106, with its surface fixedly connected to the inner wall of the bearing plate 106. The bearing bracket 3 provides reliable rotational support for the transmission screw 102, ensuring its coaxiality and stability during operation and reducing motion deviations caused by eccentricity or vibration. The surface of the servo motor 101 is fixedly connected to the left side surface of the bearing plate 106, and the two ends of the transmission screw 102 are rotatably connected to the inner wall of the bearing plate 106. The surface of the connecting plate 103 is slidably connected to the inner wall of the guide groove 107. The mounting plate 1... The lower surface of the connecting plate 104 is slidably connected to the upper surface of the bearing plate 106. The guide groove 107 provides guidance for the movement of the connecting plate 103, preventing it from shifting or jamming during movement, ensuring the synchronicity and reliability of the clamping action, and allowing the clamping plate 105 to be adjusted according to the cylinder head size. The upper end of the lifting rod 6 is fixedly connected to the lower surface of the fixed plate 201, and the lower end of the bearing plate 106 is fixedly connected to the upper surface of the mating plate 202. The upper two sides of the lifting rod 6 and the lower two sides of the mating plate 202 are fixedly connected to the surface of the support plate 204. The bearing plate 106 always maintains synchronous movement during lifting or angle adjustment, thereby preventing instability during lifting or clamping. The middle surface of the transmission screw 102 is rotatably connected to the inner wall of the bearing bracket 3.The bearing bracket 3 improves the coaxiality and operational smoothness of the transmission screw 102 during rotation, reduces transmission errors caused by eccentricity or bending, and thus enhances the operational accuracy of the fixing device 1.

[0018] The working principle of this utility model is as follows: When assisting in the assembly of the cylinder head of a diaphragm compressor, the entire auxiliary assembly device should first be moved to one side of the cylinder head assembly area of ​​the diaphragm compressor, and the mounting base 4 should be placed stably on the ground to ensure the stability of the entire device in subsequent operations. Next, the cylinder head to be assembled is placed stably on the support plate 106 at the upper end of the lifting rod 6. At this time, it is necessary to confirm that the position of the cylinder head is centered and consistent with the subsequent assembly direction. Then, the servo motor 101 on one side of the support plate 106 is started, and the servo motor 101 transmits power through its input... The output shaft drives the transmission screw 102 inside the bearing plate 106 to rotate. Since the threads at both ends of the transmission screw 102 turn in opposite directions, when the transmission screw 102 rotates, the two connecting plates 103 on its surface will move towards or away from the center along the guide groove 107 on the bearing plate 106 under the action of the threaded engagement. During the operation of clamping the cylinder head, the two connecting plates 103 will gradually move closer to the center, thereby driving the clamping plate 105 of its upper mounting plate 104 to synchronously approach the two sides of the cylinder head. In this way, the cylinder head is clamped. The clamping and fixing of the cylinder head is achieved using a flexible material for the clamping plate 105, which effectively conforms to the cylinder head surface during clamping, improving the stability and reliability of the clamping and preventing loosening due to vibration or external force. Once the cylinder head is securely clamped, the hydraulic pump 5 is activated, driving the lifting rod 6 upward to raise the bearing plate 106 and the cylinder head to the predetermined assembly height. During this process, the stability of the lifting process must be closely monitored to ensure that the cylinder head does not tilt or sway during the rise. If the angle of the bearing plate 106 needs to be adjusted to better match the spatial angle requirements of the assembly position, the current height of the cylinder head should be locked by the hydraulic lock before adjustment to prevent accidental descent during angle adjustment. Subsequently, by controlling the pressure control valve, the hydraulic cylinders 203 on both sides of the lower end of the bearing plate 106 extend and retract, thereby achieving a fine adjustment of the overall tilt angle of the bearing plate 106. After the angle adjustment is completed, it should be confirmed again that the position of the cylinder head meets the assembly requirements. After completing the above preparations, the formal assembly operation of the cylinder head can begin.

[0019] The specific models and specifications of the hydraulic pump 5, lifting rod 6, servo motor 101, transmission screw 102, hydraulic cylinder 203, and bearing bracket 3 proposed in this application need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0020] The wiring connection methods and control methods of the hydraulic pump 5, servo motor 101, pressure control valve, and hydraulic lock proposed in this application are all existing technologies in this field, and therefore will not be described in detail.
