Description

Technical Field

[0001] This utility model belongs to the field of compressor housing processing technology, specifically relating to a processing limiting seat for a refrigeration compressor housing. 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.

[0003] In the prior art, Chinese utility model patent CN219542901 U discloses "a compressor housing processing fixture", which includes a base, sliding blocks, threaded rods, a fixture panel, a first support plate, a connecting rod, and a second support plate. The base is provided with two sliding blocks, each with a threaded rod movably mounted inside via a threaded groove. This utility model incorporates a limiting gear and an elastic locking block.

[0004] Although the existing compressor housing machining limiting device can engage with the elastic block through the limiting gear, so that the teeth on the limiting gear will contact the elastic block when the connecting rod rotates, and the rotational force is continued to be applied at this time, since the elastic block is made of elastic material, it can not affect the rotation of the second support plate and can also play a limiting role. However, in actual use, because the threaded rod relies on manual operation and does not have a corresponding self-locking structure, the threaded rod is prone to reverse rotation due to machining vibration or external force interference after clamping, which will cause the fixture panel to loosen, affecting the positioning stability and machining accuracy of the compressor housing.

[0005] To address the aforementioned issues, this application proposes a machining limit seat for the housing of a refrigeration compressor. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, this utility model provides a machining limiting seat for the housing of a refrigeration compressor, which features the ability to prevent the fixture panel from loosening and improve the positioning stability and machining accuracy of the compressor housing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a processing limiting seat for a refrigeration compressor housing, comprising a base, wherein a bearing plate and two symmetrically distributed mounting seats are fixedly connected to the top of the base, and each mounting seat is vertically provided with two fixing frames in the form of square rods;

[0008] The two sets of U-shaped connecting frames utilize the open ends of their own U-shaped structures to respectively fit onto the outer walls of the corresponding fixed frames and form a vertical sliding fit. The position is locked by bolts that penetrate the vertical section of the U-shaped connecting frame and abut against the outer wall of the fixed frame.

[0009] Two U-shaped frames are respectively set on two pairs of U-shaped connecting frames, and each U-shaped frame is equipped with a linear guide rail inside;

[0010] The toothed plate forms a horizontal sliding pair with the U-shaped frame via the linear guide rail, and a clamping plate is fixed at its front end.

[0011] Two sets of drive components are respectively located in two U-shaped frames, used to drive the two clamping plates to hold the workpiece to be processed;

[0012] Two sets of limiting components are respectively set on two U-shaped frames to restrict the autonomous movement of the toothed plate.

[0013] Preferably, the drive assembly includes a fixed rod rotatably connected inside the U-shaped frame, a first gear meshing with the toothed plate is fixedly connected to the outer wall of the fixed rod, and the extended end of the fixed rod passes through the U-shaped frame and is fixedly connected to a handwheel.

[0014] Preferably, the limiting component includes a ratchet disposed on the outer wall of the fixed rod, a pawl that cooperates with the ratchet is rotatably connected to one side of the U-shaped frame, and a handle is fixedly connected to one side of the pawl.

[0015] Preferably, the bottom of the U-shaped frame is provided with a fixing block, and one side of the clamping plate is provided with a guide rod, with one end of the guide rod sliding through the fixing block.

[0016] Preferably, a second gear that meshes with the toothed plate is rotatably connected inside the U-shaped frame at a position away from the first gear.

[0017] Preferably, both clamps are provided with silicone pads on the side closest to the workpiece.

[0018] Preferably, the fixing frame is provided with support plates on both sides, and one side of the support plate is fixedly connected to the mounting base.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] In this invention, by setting a sliding fit between the U-shaped connecting frame and the fixed frame and a bolt locking structure, the height of the U-shaped frame can be flexibly adjusted, effectively expanding the applicability of the device and adapting to the processing requirements of refrigeration compressor housings of different sizes. Through the synergistic effect of the drive component and the limiting component, not only is the stable clamping of the workpiece by the clamping plate ensured, but the clamping efficiency and processing accuracy are also greatly improved. This effectively prevents the workpiece from shifting or loosening during processing, providing a strong guarantee for the high-precision processing of refrigeration compressor housings.

[0029] 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.

[0030] Example

[0031] Please see Figures 1-5This utility model provides the following technical solution: a processing limiting seat for a refrigeration compressor housing, including a base 1, a bearing plate 2 and two symmetrically distributed mounting seats 3 fixedly connected to the top of the base 1, and two fixed frames 4 with square rod structures vertically arranged on each mounting seat 3; two sets of U-shaped connecting frames 15 utilize their own U-shaped structure opening ends to respectively fit onto the outer wall of the corresponding fixed frame 4 and form a vertical sliding fit, and the position is locked by bolts 16 that penetrate the vertical section of the U-shaped connecting frame 15 and abut against the outer wall of the fixed frame 4; two U-shaped frames 6 are respectively set on the two pairs of U-shaped connecting frames 15, each The U-shaped frame 6 is equipped with linear guide rails inside; the toothed plate 7 forms a horizontal sliding pair with the U-shaped frame 6 through the linear guide rails, and a clamping plate 8 is fixed at its front end; two sets of drive components are respectively located in the two U-shaped frames 6 to drive the two clamping plates 8 to clamp the workpiece to be processed; two sets of limiting components are respectively located on the two U-shaped frames 6 to limit the autonomous movement of the toothed plate 7; during use, the user can adjust the height of the U-shaped frame 6 in advance through the sliding cooperation between the U-shaped connecting frame 15 and the fixed frame 4, and the locking action of the bolts 16, to adapt to workpieces of different sizes and increase the applicability of the device;

[0032] Next, place the refrigeration compressor housing to be processed on top of the support plate 2, ensuring that the part of the housing to be clamped corresponds to the area between the two clamping plates 8; then operate the drive assembly to drive the clamping plates 8 closer to the workpiece and clamp it in place:

[0033] During the process of the drive assembly moving the toothed plate 7, the limiting assembly simultaneously plays an anti-loosening role, preventing the toothed plate 7 from driving the clamping plate 8 to retract autonomously due to external forces such as vibration and cutting force generated during the processing, thereby preventing the clamping plate 8 from loosening and the workpiece from shifting.

[0034] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the drive assembly includes a fixed rod 10 rotatably connected inside the U-shaped frame 6. The outer wall of the fixed rod 10 is fixedly connected to a first gear 11 that meshes with the toothed plate 7. The extended end of the fixed rod 10 passes through the U-shaped frame 6 and is fixedly connected to a handwheel 12. In use, the operator can rotate the handwheel 12. The rotation of the handwheel 12 drives the fixed rod 10 to rotate synchronously. The rotation of the fixed rod 10 further drives the first gear 11 to rotate. Since the first gear 11 meshes with the toothed plate 7, the rotation of the first gear 11 will drive the toothed plate 7 to move horizontally along the linear guide rail. The movement of the toothed plate 7 drives the clamping plate 8 fixed at the front end to move closer to the housing of the refrigeration compressor to be processed until a tight clamping and fixing is achieved.

[0035] Preferably, by Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, the limiting component includes a ratchet 18 disposed on the outer wall of the fixed rod 10. A pawl 19 cooperating with the ratchet 18 is rotatably connected to one side of the U-shaped frame 6, and a handle 20 is fixedly connected to one side of the pawl 19. During the process of the drive assembly driving the toothed plate 7 to move, the ratchet 18 will rotate synchronously with the fixed rod 10. Under the action of the spring and gravity, the pawl 19 will always maintain contact with the ratchet 18. When the ratchet 18 rotates in a certain direction, the pawl 19 will jump over the teeth of the ratchet 18. When the ratchet 18 attempts to rotate in the opposite direction, the pawl 19 will engage with the teeth of the ratchet 18. The ratchet 19 is positioned between the teeth, thus preventing the ratchet 18 and the fixing rod 10 from rotating in the opposite direction. The operator can rotate the handle 20 to temporarily separate the pawl 19 from the ratchet 18 in order to make necessary adjustments or loosen the clamping plate 8. This design ensures that the clamping plate 8 remains stable after clamping the workpiece, effectively preventing the clamp from loosening due to vibration or external force during processing, and further improving the positioning stability and processing accuracy of the compressor housing. The cooperative design of the pawl 19 and the ratchet 18 not only enhances the stability and reliability of the device, but also provides the operator with a convenient and efficient adjustment and clamping solution.

[0036] Preferably, by Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, the bottom of the U-shaped frame 6 is provided with a fixing block 13, and one side of the clamping plate 8 is provided with a guide rod 14, and one end of the guide rod 14 slides through the fixing block 13; the design of the guide rod 14 enhances the stability of the clamping plate 8 during movement, ensuring that the clamping plate 8 can slide smoothly along the predetermined trajectory, avoiding damage to the workpiece due to deviation or shaking.

[0037] Preferably, by Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, a second gear 17 that meshes with the toothed plate 7 is rotatably connected inside the U-shaped frame 6 at a position away from the first gear 11. The second gear 17 provides additional driving force, ensuring that the toothed plate 7 moves more smoothly and is subjected to uniform force during movement. This prevents uneven force or jamming from occurring when the toothed plate 7 moves, thereby further improving the stability and accuracy of clamping.

[0038] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown in this embodiment, both clamping plates 8 are provided with silicone pads 9 on the side closest to the workpiece to be processed. The design of the silicone pads 9 increases the friction between the clamping plates 8 and the workpiece to be processed, effectively preventing the workpiece from sliding or shifting during clamping. At the same time, the soft material of the silicone pads 9 can also protect the surface of the workpiece, avoiding scratches or damage during clamping.

[0039] Preferably, by Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the fixed frame 4 is provided with support plates 5 on both sides, and one side of the support plate 5 is fixedly connected to the mounting base 3. The design of the support plate 5 not only enhances the stability of the fixed frame 4, but also makes the structure of the entire processing limit seat more robust and durable. During installation and use, the support plate 5 can effectively distribute and bear the weight and stress from the fixed frame 4 and the U-shaped frame 6 and other components, preventing deformation or damage caused by long-term use or excessive load.

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

[0041] The working principle and usage process of this utility model are as follows: First, adjust the vertical position of the U-shaped frame 6 according to the height specifications of the refrigeration compressor housing to be processed. Since the fixed frame 4 is a square rod structure, the U-shaped connecting frame 15 can be sleeved on the outer wall of the fixed frame 4 through its own U-shaped opening and slide along the vertical direction. At this time, first loosen the bolt 16 that passes through the vertical section of the U-shaped connecting frame 15 to release the clamping force of the bolt 16 on the outer wall of the fixed frame 4. Then push the U-shaped connecting frame 15 to drive the U-shaped frame 6, toothed plate 7 and clamping plate 8 to move up and down synchronously until the height of the clamping plate 8 is flush with the part of the housing to be clamped. After the adjustment is completed, tighten the bolt 16 again so that the end of the bolt 16 is tightly pressed against the outer wall of the fixed frame 4. Lock the position of the U-shaped connecting frame 15 through friction to avoid height deviation due to vibration during subsequent processing.

[0042] During this process, the support plates 5 on both sides of the fixed frame 4 can distribute the vertical load borne by the fixed frame 4, enhance the connection stability between the fixed frame 4 and the mounting base 3, prevent the fixed frame 4 from bending and deforming due to long-term stress, and ensure the reliability of the adjustment structure.

[0043] The refrigeration compressor housing to be processed is placed stably on the support plate 2 on the top of the base 1. The support plate 2 is used as the reference surface to ensure that the housing is placed horizontally. At the same time, the position of the housing is adjusted so that the clamping areas on both sides of the housing are precisely aligned with the space between the two clamping plates 8, laying the foundation for the symmetry and stability of subsequent clamping.

[0044] The drive assembly moves the clamping plate 8 toward the workpiece and completes the clamping. The operator rotates the handwheel 12 on the outside of the U-shaped frame 6. The handwheel 12 transmits the rotational force to the fixed rod 10, which is fixedly connected, so that the fixed rod 10 rotates synchronously inside the U-shaped frame 6. The first gear 11 on the outer wall of the fixed rod 10 rotates with the rod. Since the first gear 11 meshes with the toothed plate 7, the rotational motion of the gear is converted into the horizontal linear motion of the toothed plate 7. The toothed plate 7 slides smoothly along the linear guide rail inside the U-shaped frame 6, thereby pushing the clamping plate 8 fixed at the front end toward the outer shell.

[0045] During this process, the second gear 17 inside the U-shaped frame 6, which is far away from the first gear 11, keeps meshing with the toothed plate 7. On the one hand, it helps to disperse the force on the toothed plate 7 and prevents the toothed plate 7 from tilting or jamming due to excessive force on one side. On the other hand, the double gear guide ensures the straightness of the toothed plate 7's movement trajectory and prevents the clamping plate 8 from shifting and causing misalignment. At the same time, the guide rod 14 on one side of the clamping plate 8 slides synchronously along the through hole of the fixing block 13, further restricting the movement direction of the clamping plate 8 and ensuring that the clamping plate 8 always moves smoothly towards the workpiece in the horizontal direction, avoiding collision damage to the workpiece surface due to shaking.

[0046] Throughout the entire process of the drive assembly moving the toothed plate 7 and the clamping plate 8 clamping the workpiece, the limiting assembly is activated synchronously to prevent reverse loosening. When the fixed rod 10 rotates, the ratchet 18 on its outer wall rotates in the same direction as the rod. Under the combined action of its own weight and the spring (not shown in the figure, which is a conventional reset structure), the pawl 19 on one side of the U-shaped frame 6 always keeps in contact with the tooth groove of the ratchet 18. When the ratchet 18 rotates in the direction of "driving the clamping plate 8 to clamp", the pawl 19 can flexibly jump over the inclined surface of the ratchet 18 teeth without obstructing the normal clamping action. If external forces such as vibration or cutting force are generated during the processing, causing the fixed rod 10 to have a tendency to rotate in the opposite direction (i.e., a tendency to loosen the clamping plate 8), the pawl 19 will quickly engage between the teeth of the ratchet 18, restricting the reverse rotation of the ratchet 18 and the fixed rod 10 through mechanical engagement, thereby preventing the toothed plate 7 from retracting on its own and the clamping plate 8 from loosening, ensuring that the workpiece is always in a stable clamping state and guaranteeing processing accuracy.

[0047] 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.
