Description

Technical Field

[0001] The utility model belongs to the technical field of spinning of liquid storage devices, and particularly relates to a clamping device for a spinning machine of a liquid storage device cylinder body. Background Art

[0002] A liquid storage device is an important component of a compressor, which plays roles of storage, gas-liquid separation, filtration, silencing and refrigerant buffering. It is composed of components such as a cylinder body, an inlet pipe, an outlet pipe, a filter screen, etc. Its working principle is as follows: The liquid storage device is assembled at the positions of an air conditioner evaporator and a compressor suction pipe, and is a protection component to prevent liquid refrigerant from flowing into the compressor and causing liquid hammer. During the use and operation of the liquid storage device component, in order to avoid impurities in the pipeline directly entering the compressor, a filter screen is installed between the inlet pipe and the outlet pipe of the liquid storage device, preventing the possibility of impurities entering the compressor.

[0003] Before processing, the cylinder body of the liquid storage device is in a hollow columnar structure with open end faces at both ends. A spinning and closing structure needs to be processed on the side wall of the cylinder body through a spinning process. When the existing automatic spinning machine clamps the liquid storage device, it often uses two clamping plates to clamp the cylinder body of the liquid storage device oppositely, or uses a conical extrusion part to extrude and clamp the cylinder body. The conical extrusion part is in line contact with the outer wall of the cylinder body, and the contact area between the fixture and the cylinder body of the liquid storage device is small, resulting in poor clamping stability of the cylinder body of the liquid storage device. Content of the Utility Model

[0004] Aiming at the above deficiencies, the utility model provides a clamping device for a spinning machine of a liquid storage device cylinder body. By opening a spindle-shaped cylindrical space inside the chuck mechanism and installing a clamping disc inside the spindle-shaped cylindrical space, the clamping disc forms circumferential clamping on the outer wall of the liquid storage device cylinder body, and the contact area between the clamping disc and the outer wall of the liquid storage device cylinder body is large, improving the clamping stability of the chuck mechanism on the liquid storage device cylinder body.

[0005] The utility model is realized through the following technical solutions:

[0006] A clamping device for a spinning machine of a liquid storage cylinder body, comprising a machine body, a synchronous motor, a rotary oil cylinder and a chuck mechanism. The machine body is installed on a hydraulic device and can move in the extending direction of the machine body. A main shaft is installed inside the machine body, and a driving rod is arranged inside the main shaft, and the driving rod is consistent with the extending direction of the main shaft. The synchronous motor is installed on the machine body, and the synchronous motor can drive the main shaft to rotate around its own axis. The rotary oil cylinder is installed at the end of the main shaft and is connected to the driving rod, and the rotary oil cylinder can drive the driving rod to move relative to the main shaft along the extending direction of the main shaft. The chuck mechanism is fixed to one end of the main shaft away from the rotary oil cylinder. The chuck mechanism includes a housing, a clamping disc and a push disc fixed to the end of the driving rod. A spindle-shaped cylindrical space is opened inside the housing. The outer wall of the clamping disc is spindle-shaped cylindrical and can slide relative to the spindle-shaped cylindrical space in the extending direction of the main shaft to change the size of the cylindrical clamping inner cavity of the clamping disc, so as to clamp the liquid storage cylinder body.

[0007] Further, the clamping disc has a relaxed state and a clamping state. The rotary oil cylinder pushes the clamping disc to slide in the extending direction of the main shaft through the driving rod, so that the clamping disc is switched from the relaxed state to the clamping state. When the clamping disc is in the clamping state, the clamping disc forms a circumferential clamping on the liquid storage cylinder body and positions the central axis of the liquid storage cylinder body at a position coinciding with the central rotation axis of the main shaft, so as to position the rotation center of the liquid storage cylinder body on the rotation axis of the main shaft.

[0008] Further, the clamping disc includes a plurality of clamping tires uniformly distributed along the circumferential direction of the spindle-shaped cylindrical space. When the clamping disc is in the clamping state, the clamping tires abut against each other and enclose a cylindrical clamping space. The diameter of the cylindrical clamping space is the same as the outer diameter of the cylinder body, so that the clamping tires can be in full contact with the liquid storage cylinder body. When the clamping disc is in the relaxed state, there is a sliding space between adjacent clamping tires.

[0009] Further, a return spring is installed between each clamping tire and the housing of the chuck device. The return spring has a force to drive the clamping tire vertically upward to switch the clamping disc from the clamping state to the relaxed state, so as to separate the clamping disc from the liquid storage cylinder body. When the push disc is separated from the clamping disc, the clamping disc is in the relaxed state, and the outer diameter of the clamping disc is the largest, which is convenient for the liquid storage cylinder body to enter the cylindrical clamping inner cavity inside the clamping disc.

[0010] Further, anti-slip patterns are formed on the inner side of the clamping tire to increase the friction between the clamping tire and the liquid storage cylinder body.

[0011] Further, an arc-shaped groove is opened at the bottom of the push disc. Along the direction close to the clamping disc, the inner diameter of the arc-shaped groove gradually increases. The arc-shaped groove has an arc-shaped extrusion surface that cooperates with the outer wall of the clamping disc, increasing the contact area between the push disc and the clamping disc, and the push disc can apply a vertically downward and inwardly directed extrusion force to the clamping disc, prompting the clamping disc to change from the expanded state to the clamping state.

[0012] Further, the housing is fixedly mounted to the main shaft. A limiting sliding groove is formed on the side wall of the push plate, and the extending direction of the limiting sliding groove is the same as that of the main shaft. A limiting sliding post protruding into the limiting sliding groove is provided on the inner side of the housing. The limiting sliding post can slide along the extending direction of the limiting sliding groove, and the limiting sliding post can limit the rotation of the push plate relative to the main shaft. The circumferential position of the push plate is fixed by the housing of the chuck mechanism, so that the push plate can only move relative to the housing in the vertical direction. Furthermore, it is very difficult for the clamping plate abutting against the push plate to slip relative to the push plate, thereby improving the stability of clamping the liquid storage cylinder body.

[0013] Further, at least one limiting sliding groove is provided, and the number of the limiting sliding posts is the same as that of the limiting sliding grooves.

[0014] Further, a guiding flaring communicating with the cylindrical clamping cavity is provided at the bottom of the clamping plate, which is convenient for the liquid storage cylinder body to enter the cylindrical clamping cavity of the clamping plate.

[0015] Further, a rubber layer is attached to the inner wall of the cylindrical clamping cavity of the clamping plate, which increases the friction between the clamping plate and the liquid storage cylinder body and can protect the liquid storage cylinder body.

[0016] Advantages of the utility model:

[0017] By providing a spindle-shaped cylindrical space inside the chuck mechanism and installing a clamping plate inside the spindle-shaped cylindrical space, the clamping plate forms a circumferential clamping on the outer wall of the liquid storage cylinder body, and the contact area between the clamping plate and the outer wall of the liquid storage cylinder body is large, thereby improving the clamping stability of the chuck mechanism on the liquid storage cylinder body.

[0031] Such as Figures 1 to 7The clamping device of a spinning machine for a liquid storage cylinder shown in the figure comprises a machine body 1, a synchronous motor 2, a rotary oil cylinder 3 and a chuck mechanism 4. The machine body 1 is mounted on a hydraulic device and can move in the extension direction of the machine body 1. A main shaft 11 is mounted in the machine body 1. A driving rod 12 is provided inside the main shaft 11. The driving rod 12 is consistent with the extension direction of the main shaft 11. The synchronous motor 2 is mounted on the machine body 1. The synchronous motor 2 can drive the main shaft 11 to rotate around its own axis. The rotary oil cylinder 3 is mounted on the end of the main shaft 11 and connected to the driving rod 12. The rotary oil cylinder 3 can drive the driving rod 12 to move relative to the main shaft 11 along the extension direction of the main shaft 11. The chuck mechanism 4 is fixed to one end of the main shaft 11 away from the rotary cylinder 3. The chuck mechanism 4 includes a shell 41, a clamping plate 42 and a push plate 43 fixed to the end of the driving rod 12. A spindle-shaped cylindrical space 44 is opened in the shell 41. The outer wall of the clamping plate 42 is spindle-shaped and cylindrical and can slide relative to the spindle-shaped cylindrical space 44 in the extension direction of the main shaft 11 to change the size of the cylindrical clamping cavity 45 of the clamping plate 42, thereby clamping the liquid reservoir cylinder.

[0032] In one embodiment, the rotary cylinder 3 can rotate with the main shaft 11, and can push the driving rod 12 located in the main shaft 11 to move relative to the main shaft 11 in the extension direction of the main shaft 11. The chuck mechanism 4 is fixed to the main shaft 11, and the synchronous motor 2 is used to drive the main shaft 11 to rotate to drive the chuck mechanism 4 to rotate. First, the hydraulic device drives the entire body 1 to move toward the reservoir cylinder until the reservoir cylinder is located in the cylindrical clamping inner cavity 45 of the clamping disk 42. The rotary cylinder 3 drives the clamping disk 42 located in the spindle-shaped cylindrical space 44 in the chuck mechanism 4 to move toward the reservoir cylinder in the extension direction of the main shaft 11 through the driving rod 12. Since the outer wall of the clamping disk 42 is also spindle-shaped and cylindrical, and the outer wall of the clamping disk 42 abuts against the inner wall of the shell 41 of the chuck mechanism 4, when the clamping disk 42 moves toward the direction close to the liquid reservoir cylinder under the action of the driving rod 12, the shell 41 of the chuck mechanism 4 has a tendency to squeeze and contract the clamping disk 42, so that the clamping disk 42 is tightened from a relaxed state to a clamped state, thereby achieving stable clamping of the liquid reservoir cylinder.

[0033] It should be noted that the hydraulic device is an existing device, which can drive the machine body 1 to slide in the extension direction of the main shaft 11, and is used to move the chuck mechanism 4 to the placement position of the liquid reservoir cylinder.

[0034] Preferably, the clamping plate 42 has a relaxed state and a clamping state. The rotary cylinder 3 pushes the clamping plate 42 to slide in the extension direction of the main shaft 11 through the driving rod 12, so that the clamping plate 42 switches from the relaxed state to the clamping state. When the clamping plate 42 is in the clamping state, the clamping plate 42 forms a circumferential clamp on the liquid reservoir cylinder and positions the central axis of the liquid reservoir cylinder at a position that coincides with the central rotation axis of the main shaft 11, so as to position the rotation center of the liquid reservoir cylinder on the rotation axis of the main shaft 11.

[0035] In one embodiment, when the clamping disc 42 clamps the liquid storage cylinder body, the central axis of the clamped liquid storage cylinder body coincides with the rotation axis of the main shaft 11, so as to improve the stability when the main shaft 11 drives the liquid storage cylinder body to rotate.

[0036] Preferably, the clamping disc 42 includes a plurality of clamping tires 421 evenly distributed along the circumferential direction of the spindle-shaped cylindrical space 44. When the clamping disc 42 is in the clamping state, the clamping tires 421 abut against each other and enclose a cylindrical clamping space. The diameter of the cylindrical clamping space is the same as the outer diameter of the cylinder body, so that the clamping tires 421 can be in full contact with the liquid storage cylinder body. When the clamping disc 42 is in the relaxed state, there is a sliding space between adjacent clamping tires 421.

[0037] In one embodiment, as Figures 2 to 7 shown, the clamping disc 42 includes a plurality of clamping tires 421. When the clamping disc 42 clamps the liquid storage cylinder body, the clamping tires 421 approach and converge towards each other, so as to form a cylindrical clamping space between the clamping tires 421, realizing circumferential clamping of the liquid storage cylinder body. The inner circumferential surface formed on the inner side of the clamping tire 421 is in full contact with the outer wall of the liquid storage cylinder body, so that there is a large clamping area between the clamping disc 42 and the liquid storage cylinder body, improving the clamping stability of the clamping disc 42 on the liquid storage cylinder body. It should be noted that in the prior art, two clamping plates or jaws are often used to clamp the liquid storage cylinder body or a conical pressing member is used to tightly fix the liquid storage cylinder body. In the above methods, the contact area between the clamping device and the liquid storage cylinder body is small and the clamping stability is poor. However, in the clamping disc 42 of the present application, a cylindrical clamping space is provided inside, so as to stably clamp the liquid storage cylinder body circumferentially. The liquid storage cylinder body is used in the field of air-conditioning refrigeration, and certain requirements are imposed on the outer wall of the liquid storage cylinder body. When a plurality of clamping tires 421 are used to circumferentially clamp the outer wall of the liquid storage cylinder body, the deformation of the liquid storage cylinder body can be reduced to a certain extent, ensuring the processing quality of the liquid storage cylinder body in the spinning process.

[0038] Preferably, a return spring 46 is installed between each clamping tire 421 and the housing 41 of the chuck device. The return spring 46 has a force to drive the clamping tire 421 vertically upward, so as to switch the clamping disc 42 from the clamping state to the relaxed state, realizing the separation of the clamping disc 42 from the liquid storage cylinder body. When the push disc 43 is separated from the clamping disc 42, the clamping disc 42 is in the relaxed state, and the outer diameter of the clamping disc 42 is the largest, facilitating the liquid storage cylinder body to enter the cylindrical clamping inner cavity 45 inside the clamping disc 42.

[0039] In one embodiment, after the processing of the liquid reservoir cylinder is completed, the rotary cylinder 3 drives the driving rod 12 to move relative to the main shaft 11 toward the direction of the rotary cylinder 3, and the push plate 43 fixed to the end of the driving rod 12 contacts and squeezes each clamping tire 421. Under the action of the reset spring 46, each clamping tire 421 moves toward the direction of the rotary cylinder 3 to increase the volume of the inner cylindrical clamping cavity 45 of the clamping plate 42, thereby releasing the clamping limit on the liquid reservoir cylinder.

[0040] Preferably, an anti-skid pattern 422 is formed on the inner side of the clamping tire 421 to increase the friction between the clamping tire 421 and the liquid reservoir cylinder.

[0041] Preferably, an arc-shaped groove is provided at the bottom of the push plate 43, and the inner diameter of the arc-shaped groove gradually increases along the direction approaching the clamping plate 42. The arc-shaped groove has an arc-shaped extrusion surface 431 that cooperates with the outer wall of the clamping plate 42, thereby increasing the contact area between the push plate 43 and the clamping plate 42, and the push plate 43 can apply an extrusion force to the clamping plate 42 vertically downward and inward, thereby causing the clamping plate 42 to change from an expanded state to a clamping state.

[0042] In one embodiment, when the push plate 43 moves toward the clamping plate 42, the push plate has an extrusion force on the clamping plate 42 to push the clamping plate 42 to move toward the direction of the liquid reservoir cylinder, and has an extrusion force to push each clamping tire 421 to retract, so as to promote the clamping plate 42 to retract inward.

[0043] Preferably, the housing 41 is fixed to the spindle 11, and a limiting slot 432 is provided on the side wall of the push plate 43. The extending direction of the limiting slot 432 is consistent with the extending direction of the spindle 11. A limiting slide post 411 extending into the limiting slot 432 is protruded from the inner side of the housing 41. The limiting slide post 411 can slide along the extending direction of the limiting slot 432, and the limiting slide post 411 can limit the rotation of the push plate 43 relative to the spindle 11. The push plate 43 is fixed in the circumferential position by the housing 41 of the chuck mechanism 4, so that the push plate 43 can only move in the vertical direction relative to the housing 41, thereby making it difficult for the clamping plate 42 abutting against the push plate 43 to slide relative to the push plate 43, thereby improving the stability of the clamping reservoir cylinder.

[0044] In one embodiment, after the clamping mechanism clamps the liquid storage cylinder body, the main shaft 11 drives the liquid storage cylinder body to rotate at a high speed through the clamping mechanism to perform a spinning operation on the liquid storage cylinder body. When the liquid storage cylinder body is subjected to the action of an external spinning device, the liquid storage cylinder body is likely to rotate and slip relative to the clamping mechanism. When the clamping mechanism clamps the liquid storage cylinder body, the liquid storage cylinder body is fixed by the clamping tire 421, and the top of the clamping tire 421 abuts against the push plate 43. In order to prevent the push plate 43 from rotating relative to the housing 41 of the clamping mechanism, a limit sliding groove 432 is formed in the push plate 43, and a limit sliding column 411 matched with the limit sliding groove 432 is arranged in the housing 41 to realize the rotational limit of the push plate 43, thereby improving the stability of the clamping mechanism when clamping the liquid storage cylinder body for spinning operation.

[0045] Preferably, at least one limit sliding groove 432 is provided, and the number of limit sliding columns 411 is the same as that of the limit sliding grooves 432.

[0046] Preferably, a guiding flared opening 423 communicating with the cylindrical clamping inner cavity 45 is provided at the bottom of the clamping disc 42, facilitating the liquid storage cylinder body to enter the cylindrical clamping inner cavity 45 of the clamping disc 42.

[0047] Preferably, a rubber layer is attached to the inner wall of the cylindrical clamping inner cavity 45 of the clamping disc 42 to increase the friction force between the clamping disc 42 and the liquid storage cylinder body and protect the liquid storage cylinder body.

[0048] When the above-mentioned clamping device for a liquid storage cylinder body of a spinning machine is adopted, a spindle-shaped cylindrical space 44 is formed inside the chuck mechanism 4, and a clamping disc 42 is installed inside the spindle-shaped cylindrical space 44. The clamping disc 42 forms a circumferential clamping on the outer wall of the liquid storage cylinder body, and the contact area between the clamping disc 42 and the outer wall of the liquid storage cylinder body is large, improving the clamping stability of the chuck mechanism 4 on the liquid storage cylinder body.

[0049] The above description is only for the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
