Description

Technical Field

[0001] This utility model belongs to the field of punching machine technology, specifically relating to a large-hole punching device for the housing of a refrigeration compressor. Background Technology

[0002] A refrigeration compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. Apart from internal components such as motors and pistons, the outer casing is an important structural component that enables its assembly and installation. The connection between the upper and lower covers provides protection and installation space for the actuator. During the production process, the upper and lower covers of the refrigeration compressor casing need to be punched.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN220591281 U discloses "a punching machine for the upper and lower covers of a refrigeration compressor housing", which includes a workbench, a support cover, and a bracket. The support cover is located on the workbench, the bracket is located on the support cover, the support cover has a sliding groove, a slider is slidably connected to the sliding groove, a fixed plate is located on the slider, a punching lifting mechanism is located on both sides of the bracket, a support plate is located on the punching lifting mechanism, the support plate is located between the support cover and the bracket, a fixed rod is threadedly connected to the support plate, the fixed rod passes through the support plate, a punching hydraulic cylinder is located at the top of the bracket, a punch head is located at the bottom of the punching hydraulic cylinder, a clamping drive mechanism is located inside the support cover, and the slider is located on the clamping drive mechanism.

[0004] However, in actual production applications, existing punching devices for the upper and lower covers of refrigeration compressor housings, including the aforementioned patent, mostly use rigid fixing methods such as bolts and pins to connect the fixing plate used to clamp the workpiece with the sliding block, push plate, and other linkage components. While this fixing method can ensure structural stability during clamping, in scenarios of multi-variety, small-batch production, when it is necessary to replace the fixing plate with different specifications to adapt to upper and lower cover workpieces of different sizes and shapes, it is necessary to use special tools such as wrenches and pin pullers to gradually disassemble the bolts or pins. The operation steps are cumbersome and time-consuming, making it impossible to achieve manual and rapid disassembly and replacement of the fixing plate. This problem leads to an extended workpiece changeover cycle, affecting production continuity and making it difficult to meet the needs of efficient and flexible production. To solve the above problems, this application proposes a large-hole punching device for refrigeration compressor housings. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a large-hole punching device for the housing of a refrigeration compressor, which facilitates quick disassembly and replacement of the fixing plate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large-hole punching device for the housing of a refrigeration compressor, comprising a worktable, a support cover on the top of the worktable, and four pairs of guide holes on the top of the support cover;

[0007] Four cylinders are symmetrically arranged on the top of the worktable, and the output end of each cylinder is connected to the moving frame.

[0008] Four fixed plates are connected to the movable frame via two connecting plates fixed at the bottom;

[0009] Four sets of connecting components are respectively installed on the four movable frames to realize the detachable connection between the fixed plate and the movable frame.

[0010] Preferably, the connecting assembly includes a limiting plate disposed on the side of the two connecting plates, a bidirectional threaded rod rotatably connected inside the movable frame, a motor for driving the bidirectional threaded rod installed on the outer wall of the movable frame, two mounting holes being provided in the movable frame, and two moving blocks being threadedly connected to the outer wall of the bidirectional threaded rod, with the moving blocks passing through the mounting holes and having limiting components.

[0011] Preferably, the bottom of the movable frame is provided with a support plate.

[0012] Preferably, the bottom of the movable frame is rotatably connected to two pairs of rollers.

[0013] Preferably, the length of the two pairs of limiting members is greater than the length of the moving block.

[0014] Preferably, the distance between the two limiting plates is the same as the height of the limiting member.

[0015] Preferably, the length of the mounting hole is adapted to the length of the limiting member.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, a detachable connection between the fixed plate and the movable frame is achieved through the design of a connecting component. Compared with traditional rigid fixing methods such as bolts and pins, this device does not require special tools when replacing the fixed plate. It only requires operating the motor to drive the bidirectional threaded rod to rotate, which can drive the limiting component to move, thus realizing the quick assembly and disassembly of the fixed plate. This greatly improves the ease of operation, shortens the workpiece changeover cycle, and effectively meets the needs of efficient and flexible production.

[0018] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0026] 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.

[0027] Example

[0028] Please see Figures 1-5 The present invention provides the following technical solution: a large hole punching device for the housing of a refrigeration compressor, including a workbench 1, a support cover 8 on the top of the workbench 1, and four pairs of guide holes 9 on the top of the support cover 8;

[0029] Four cylinders 2 are symmetrically arranged on the top of the workbench 1, and the output end of each cylinder 2 is connected to the moving frame 3;

[0030] Four fixed plates 4 are connected to the movable frame 3 via two connecting plates 5 fixed to the bottom;

[0031] Four sets of connecting components 100 are respectively set on four movable frames 3 to realize the detachable connection between the fixed plate 4 and the movable frame 3. In use, the refrigeration compressor housing is placed on the workbench 1, the cylinder 2 is started, and its output end pushes the movable frame 3 to move along the four pairs of guide holes 9 on the top of the support cover 8. The four pairs of guide holes 9 can guide and limit the movement of the movable frame 3, effectively improving its stability during the movement process. As the movable frame 3 moves, the fixed plate 4 connected to it moves closer to and clamps and fixes the refrigeration compressor housing.

[0032] The fixing plate 4 is equipped with a punching device in the prior art (such as the punching hydraulic cylinder, punch and other punching execution components disclosed in the patent with authorization announcement number CN220591281 U). After the fixing plate 4 completes the clamping and fixing of the refrigeration compressor housing, the existing punching device can cooperate with the precise positioning after clamping to perform punching operation on the refrigeration compressor housing.

[0033] When it is necessary to adapt to different specifications of refrigeration compressor housings or replace the corresponding specifications of the fixed plate 4, the fixed plate 4 and the moving frame 3 can be directly detached and replaced by operating the connecting component 100. There is no need to use special tools such as wrenches or pin pullers. The operation steps are simple and quick, which can effectively shorten the workpiece changeover cycle, ensure production continuity, and meet the needs of high-efficiency and flexible production.

[0034] Preferably, by Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, the connecting assembly 100 includes limiting plates 106 disposed on the sides of the two connecting plates 5. A bidirectional threaded rod 101 is rotatably connected inside the moving frame 3. A motor 102 for driving the bidirectional threaded rod 101 is installed on the outer wall of the moving frame 3. The moving frame 3 has two mounting holes 105. Two moving blocks 103 are threadedly connected to the outer wall of the bidirectional threaded rod 101. The moving blocks 103 pass through the mounting holes 105 and are provided with limiting members 104. In use, when it is necessary to install the fixing plate 4, the motor 102 is started first, so that the bidirectional threaded rod 101 rotates, thereby driving the two moving blocks 103 to move relative to each other within the mounting holes 105. When the two moving blocks 103 move relative to each other, the moving blocks 103 will drive the limiting members 104 on them to move, so that the position of the limiting members 104 is aligned with the position of the mounting hole 105. At this time, the two connecting plates 5 can be passed through the two guide holes 9, so that one side of them fits against one side of the moving frame 3. Then, the motor 102 is started in reverse, so that the bidirectional threaded rod 101 rotates in the opposite direction, driving the two moving blocks 103 to move in opposite directions within the mounting hole 105, thereby driving the limiting members 104 to move towards the connecting plates 5, until the limiting members 104 are engaged between the two limiting plates 106, thus fixing the fixing plate 4. When it is necessary to remove the fixing plate 4, simply start the motor 102, so that the bidirectional threaded rod 101 rotates, driving the two moving blocks 103 to move in opposite directions within the mounting hole 105, so that the limiting members 104 disengage from the limiting plates 106, and the fixing plate 4 can be easily removed from the moving frame 3, achieving quick disassembly and replacement.

[0035] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, the bottom of the movable frame 3 is provided with a support plate 7; the support plate 7 is provided so that the bottom of the connecting plate 5 can contact the support plate 7, so that the limiting member 104 can move accurately between the two limiting plates 106, thereby improving the installation accuracy and stability.

[0036] Preferably, by Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the bottom of the movable frame 3 is rotatably connected with two pairs of rollers 6; this increases the flexibility of the movable frame 3 when moving, while reducing the friction between the movable frame 3 and the worktable 1 and extending its service life. The design of the rollers 6 allows the movable frame 3 to move more smoothly along the guide hole 9 under the push of the cylinder 2, ensuring the stability and accuracy of the punching operation.

[0037] Preferably, by Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, the length of the two pairs of limiting members 104 is greater than the length of the moving block 103; this allows the limiting members 104 to have sufficient moving space within the mounting hole 105, ensuring that the limiting members 104 can smoothly engage or disengage from the limiting plate 106, thereby achieving reliable fixing and convenient disassembly of the fixing plate 4.

[0038] Preferably, by Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, the distance between the two limiting plates 106 is consistent with the height of the limiting member 104; this ensures that when the limiting member 104 is inserted between the two limiting plates 106, it can stably fix the fixing plate 4, preventing it from shaking or falling off during operation, and improving the accuracy and safety of the punching operation.

[0039] Preferably, by Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, the length of the mounting hole 105 is adapted to the length of the limiting member 104, so that the limiting member 104 can move to a position aligned with the mounting hole 105, thereby avoiding interference with the downward movement of the connecting plate 5. At the same time, it ensures that the limiting member 104 has sufficient travel within the mounting hole 105 to achieve a firm fixation and convenient disassembly of the fixing plate 4.

[0040] Components not described in detail in this article are existing technologies.

[0041] The working principle and usage process of this utility model: When in use, the operator first selects the appropriate fixing plate 4 according to the specifications of the refrigeration compressor housing to be processed, and then aligns it with the moving frame 3 through the two connecting plates 5 at the bottom. When the motor 102 is not started, the limiting member 104 is in the initial position and will not hinder the insertion of the connecting plate 5. The operator smoothly inserts the connecting plate 5 along the guide hole 9 until it is tightly fitted with one side of the moving frame 3.

[0042] Next, the motor 102 is started, and the output shaft of the motor 102 drives the bidirectional threaded rod 101 to rotate. Since the bidirectional threaded rod 101 is connected to the two moving blocks 103 by threads, as the bidirectional threaded rod 101 rotates, the two moving blocks 103 will move in opposite directions within the mounting hole 105. This movement process drives the limiting member 104 to gradually approach and finally lock into the two limiting plates 106, thereby effectively fixing the fixing plate 4.

[0043] After the fixed plate 4 has finished clamping and fixing the refrigeration compressor housing, the punching device can be started to perform punching operations. After the punching operation is completed, if it is necessary to replace the fixed plate 4 of different specifications to adapt to the new workpiece, the operator only needs to start the motor 102 again to make the bidirectional threaded rod 101 rotate in the opposite direction, driving the two moving blocks 103 to move in opposite directions in the mounting hole 105, so that the limiting member 104 is freed from the constraint of the limiting plate 106. At this time, the operator can easily remove the fixed plate 4 together with the connecting plate 5 on it from the moving frame 3 and replace it with a new matching fixed plate 4.

[0044] Throughout the process, no special tools such as wrenches and pin pullers are needed, which greatly simplifies the operation steps, shortens the workpiece changeover cycle, and effectively ensures the continuity and efficiency of production. At the same time, the design of the device also fully considers the issues of installation accuracy and stability. Through the setting of the support plate 7 and the precise cooperation between the limiting part 104 and the limiting plate 106, the stability and safety of the fixed plate 4 during the working process are ensured.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
