Description

Technical Field

[0001] This utility model relates to the field of valve plate processing technology, specifically to a direct-pin pre-compression device for a compressor valve plate. Background Technology

[0002] Compressors are indispensable equipment in refrigeration systems, air conditioning systems, and many industrial fields. As one of the key components of a compressor, the performance of the valve plate directly affects the overall efficiency and reliability of the compressor. The pins on the valve plate play an important role in connecting the valve plates, transmitting force, and ensuring the accuracy of valve plate movement during compressor operation.

[0003] Most existing technologies cannot control the pressure level. This lack of pressure control leads to inconsistent pre-compression states on the direct pins of each valve plate, resulting in inconsistent product quality, affecting overall product quality and brand image. Furthermore, uneven pressure may cause inconsistent clearances between the direct pins and the valve plate, preventing proper sealing, leading to gas leakage, and reducing the compressor's compression ratio and cooling or heating performance. Therefore, we propose a direct pin pre-compression device for compressor valve plates. Utility Model Content

[0004] The purpose of this utility model is to provide a direct-pin pre-compression device for a compressor valve plate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a direct pin pre-compression device for a compressor valve plate, comprising a slide rail, a top plate disposed on the top of the slide rail, a base disposed on the slide rail, and a receiving platform disposed on the slide rail, and further comprising:

[0006] A buffer assembly includes a buffer rod disposed on the top of a base, the top of the buffer rod being connected to the bottom of a support platform, a buffer block being connected to the bottom of the buffer rod, a first sliding groove being provided on the side of the top of the base near the buffer block, the first sliding groove being slidably connected within the first sliding groove, and a first spring being fixedly connected between the buffer block and the first sliding groove, the first spring being provided with damping.

[0007] The pressure equalization assembly includes a bracket mounted on the top of a base, a gear mounted on the bracket, a rotating shaft rotatably connected to the gear and the bracket, a connecting plate connected to the rotating shaft, a rocker arm mounted on the connecting plate, a connecting rod connected to a buffer block, the connecting rod being connected to the rocker arm, a rack mounted on the top of the base and meshing with the gear, and a fixing plate mounted on the top of the base with a button.

[0008] Furthermore, a second sliding groove is provided on the top of the base near the rack, and a slider is provided in the second sliding groove, with the rack and slider being fixedly connected.

[0009] The above technical solution is adopted: by setting a second slide and a slider, the movement trajectory of the rack is limited to prevent it from deviating.

[0010] Furthermore, a valve plate body is provided on the top of the receiving platform, and a straight pin body is provided on the top of the valve plate body. The receiving platform is slidably connected to the slide rail.

[0011] The above technical solution makes the receiving platform more stable during its up-and-down movement.

[0012] Furthermore, a positioning component is provided on the side of the receiving platform near the valve plate body. The positioning component includes a fixed seat, a limit plate is connected to the valve plate body, a slot is provided on the fixed seat, a second spring is provided in the slot, and a limit block is connected to the second spring.

[0013] The above technical solution involves setting a positioning component to limit the valve plate and prevent deviation during processing.

[0014] Furthermore, the limiting block is slidably connected within the slot, and the top of the limiting block is set as an inclined surface.

[0015] The above technical solution makes the snap-fit ​​and disassembly process more convenient.

[0016] Furthermore, a pre-compression assembly is provided on the top plate, the pre-compression assembly including a hydraulic cylinder, and a pressure plate is fixedly connected to the output end of the hydraulic cylinder.

[0017] The above technical solution involves pre-compressing the pins on the valve plate by setting up a pre-compressing component.

[0018] Furthermore, the base has an installation groove at the top, and a telescopic rod is slidably connected to the bottom of the rocker arm, with the connecting rod connected to the telescopic rod.

[0019] The above technical solution involves setting up an installation slot, in which a sensor can be installed. When the button is touched, the hydraulic cylinder automatically stops working.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, by setting up a pressure equalization component, the pre-pressure of each pin is ensured to be the same, enabling precise control of the opening and closing time and stroke. This allows for more accurate control of the gas inflow and outflow volume and timing, solving the problem that most existing technologies cannot control the pressure. The inability to control the pressure results in different pre-pressure states for each pin on the valve plate, leading to inconsistent product quality, failure to guarantee product consistency, and impacting the overall product quality and brand image. Furthermore, uneven pressure may cause inconsistent clearance between the pin and the valve plate, preventing a good seal, resulting in gas leakage, and reducing the compressor's compression ratio and cooling or heating effect.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-4 As shown, this utility model provides a technical solution: a direct pin pre-compression device for a compressor valve plate, including a slide rail 1, a top plate 2 disposed on the top of the slide rail 1, a base 3 disposed on the slide rail 1, and a receiving platform 4 disposed on the slide rail 1, and further including:

[0036] The buffer assembly 5 includes a buffer rod 51 disposed on the top of the base 3. The top of the buffer rod 51 is connected to the bottom of the support platform 4. A buffer block 53 is connected to the bottom of the buffer rod 51. A first groove 52 is provided on the side of the top of the base 3 near the buffer block 53. The first groove 52 is slidably connected in the first groove 52. A first spring 54 is fixedly connected between the buffer block 53 and the first groove 52. A damping 55 is provided in the first spring 54.

[0037] The pressure equalization component 6 includes a bracket 61 mounted on the top of the base 3, a gear 62 mounted on the bracket 61, a rotating shaft 63 rotatably connected between the gear 62 and the bracket 61, a connecting plate 66 connected to the rotating shaft 63, a rocker arm 65 mounted on the connecting plate 66, a connecting rod 64 connected to the buffer block 53, the connecting rod 64 connected to the rocker arm 65, a rack 67 mounted on the top of the base 3, the rack 67 meshing with the gear 62, a fixing plate 68 mounted on the top of the base 3, a button 69 mounted on the fixing plate 68, an installation groove 12 opened on the top of the base 3, a telescopic rod slidably connected to the bottom of the rocker arm 65, and the connecting rod 64 connected to the telescopic rod.

[0038] Specifically, when the receiving platform 4 receives downward pressure, it will cause the bottom buffer rod 51 to slide. The buffer rod 51 will cause the buffer block 53 to slide in the first slide groove 52. During the sliding process, it will squeeze the first spring 54 and the internal damper 55 for buffering. When the buffer block 53 slides, it will cause the connecting rod 64 to move. The connecting rod 64 will drive the rocker arm 65 to rotate. The rocker arm 65 will drive the rotating shaft 63 to rotate. The rotating shaft 63 will drive the gear 62 to rotate. The gear 62 will drive the rack 67 to slide. When the rack 67 touches the button 69, the sensor in the mounting groove 12 will send a command to the hydraulic cylinder 91 to stop working and maintain the pressure of each processing.

[0039] Furthermore, such as Figure 1As shown: A pre-compression assembly 9 is provided on the top plate 2. The pre-compression assembly 9 includes a hydraulic cylinder 91. The output end of the hydraulic cylinder 91 is fixedly connected to a pressure plate 92. A valve plate body 8 is provided on the top of the receiving platform 4. A straight pin body 10 is provided on the top of the valve plate body 8. The receiving platform 4 is slidably connected to the slide rail 1. When the hydraulic cylinder 91 is opened, it drives the pressure plate 92 to press down. The pressure plate 92 pre-compresses the straight pin.

[0040] The above solution also has the problem that rack 67 may deviate and wobble during movement, such as... Figure 2 As shown: A second slide groove 11 is provided on the top side of the base 3 near the rack 67. A slider is provided in the second slide groove 11. The rack 67 is fixedly connected to the slider. When the rack 67 moves, it will drive the slider to slide in the second slide groove 11 in a synchronous manner, thereby limiting the rack 67.

[0041] The above solutions also have the problem that the valve plate is not positioned during processing, which can easily lead to its displacement. Figure 4 As shown: A positioning component 7 is provided on the side of the receiving platform 4 near the valve plate body 8. The positioning component 7 includes a fixed seat 71, a limiting plate 72 connected to the valve plate body 8, a slot 73 opened on the fixed seat 71, a second spring 75 is provided in the slot 73, a limiting block 74 is connected to the second spring 75, the limiting block 74 is slidably connected in the slot 73, and the top of the limiting block 74 is set as an inclined surface. When the limiting plate 72 contacts the limiting block 74, it will squeeze the limiting block 74 into the slot 73. Subsequently, when the limiting plate 72 separates from the limiting block 74, the limiting block 74 will automatically reset and position the valve plate by the elastic force of the second spring 75.

[0042] The working principle provided by this utility model is as follows: Figures 1-4As shown: First, the valve plate is placed on top of the receiving platform 4. When the limiting plate 72 contacts the limiting block 74, it will squeeze the limiting block 74 into the slot 73. Then, after the limiting plate 72 separates from the limiting block 74, the limiting block 74 will automatically reset and position the valve plate by the elastic force of the second spring 75. Then, the hydraulic cylinder 91 is activated to drive the pressure plate 92 to press down. The pressure plate 92 pre-presses the straight pin. When the receiving platform 4 receives downward pressure, it will drive the bottom buffer rod 51 to slide. The buffer rod 51 drives the buffer block 53 to slide in the first slide groove 52. During the sliding process, it will squeeze the first... Spring 54 and internal damper 55 provide buffering. When buffer block 53 slides, it drives connecting rod 64 to move. Connecting rod 64 drives rocker arm 65 to rotate. Rocker arm 65 drives rotating shaft 63 to rotate. Rotating shaft 63 drives gear 62 to rotate. Gear 62 drives rack 67 to slide. When rack 67 moves, it synchronously drives slider to slide in second slide groove 11, limiting rack 67. When rack 67 presses against button 69, sensor in mounting groove 12 sends a command to hydraulic cylinder 91, thereby stopping work and maintaining uniform pressure for each processing.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced.
