Description

Technical Field

[0002] With the continuous improvement of living standards, air conditioners are becoming more and more popular in people's daily lives. As the core component of air conditioners, the demand for compressors is increasing day by day. During the production process of the compressor, it is necessary to press the upper and lower covers into the upper and lower ends of the shell respectively. During the actual pressing process of the upper and lower covers, the pressure cover in the pressing device is often misaligned with the compressor and is not coaxial, resulting in failure of the pressing action of the upper and lower covers, affecting the production rhythm. The common pressing devices on the market cannot ensure that the pressing tool and the clamping tool are raised and lowered at the same time to complete the clamping of the compressor. Therefore, the production rhythm is generally slow. At the same time, in the existing pressing devices, it is inevitable that the pressure cover is pressed down due to the non-coaxiality of the compressor, resulting in failure of the pressing of the upper and lower covers of the compressor. Because there is no effective mechanism to limit the rotation timing of the screw rod, it often happens that when the pressing assembly is pressed down, the screw rod rotates, resulting in a pressing failure.

[0044] Implementation case 1:

[0045] like Figure 1As shown, a compressor upper and lower cover pressing device comprises a bottom plate 1, a turntable 2 and an assembly line 7 are arranged above the bottom plate 1, the compressor and the upper cover are pre-assembled on the assembly line 7, the lower cover is placed on the turntable 2, the compressor and the upper cover are transferred to the turntable 2, and placed on the upper end of the lower cover, and the pressing action of the upper and lower covers is achieved by applying a pressing force;

[0046] like Fig.12 As shown, a plurality of placement grooves 21 are evenly arranged around the upper end of the turntable 2, and the placement grooves 21 are used to position the lower cover. A motor is fixed to the upper end of the base plate 1 to drive the turntable 2 to rotate. After the upper and lower covers of the compressor are pressed together, the compressor that has completed the pressing action is removed by rotating the turntable, and the upper and lower covers of the next compressor are pressed together.

[0047] A pressing mechanism 3 is installed at the upper end of the bottom plate 1, and the pressing mechanism 3 is used to transfer the compressor from the assembly line 7 to the turntable 2 and press the upper and lower covers of the compressor;

[0048] like Figure 2-4 As shown, the pressing mechanism 3 includes a mounting frame 31, which is fixed to the upper end of the base plate 1, and a pressing assembly 32 and a transplanting assembly 33 are installed on the upper end of the mounting frame 31, and the pressing assembly 32 and the transplanting assembly 33 are used to press the compressor and transplant the compressor on the assembly line 7 to the turntable 2 respectively;

[0049] The pressing assembly 32 includes a first slider 321, which is slidably connected to the upper end surface of the mounting frame 31. A first rack 322 is slidably connected to the first slider 321, and the sliding direction is the vertical direction. A first gear 323 is vertically provided on the first slider 321 and meshes with the first rack 322. A first driving device 324 for driving the first gear 323 to rotate is fixed to the first slider 321. The lifting movement of the first rack 322 is achieved by controlling the operation of the first driving device 324. A pressure cover 325 is fixed to the lower end of the first rack 322. The pressure cover 325 can act on the upper cover of the compressor, and can achieve the pressing action of the upper and lower covers of the compressor under the drive of the first driving device 324.

[0050] The transplanting assembly 33 includes a second slider 331, which is slidably connected to the upper end surface of the mounting frame 31. A cylinder 332 is fixed on the second slider 331, and a clamping claw 334 is fixed on the lower end of the cylinder 332. The clamping claw 334 is used to clamp the compressor, and the cylinder 332 is used to lift the compressor. As the second slider 331 slides on the mounting frame 31, the compressor is transplanted.

[0051] The second slider 331 and the first slider 321 can be connected to each other, and the first slider 321 and the second slider 331 can slide synchronously on the upper end of the mounting frame 31, so as to avoid the second slider 331 and the first slider 321 sliding separately and causing interference between the transplanting assembly 33 and the pressing assembly 32; a first fixing plate 333 is provided on one side of the second slider 331, and two second fixing plates 311 are provided on one side of the mounting frame 31, and a screw rod 35 is rotatably connected between the two second fixing plates 311, and the screw rod 35 passes through the first fixing plate 333 and is threadedly connected thereto, and a second driving device is fixed on one of the second fixing plates 311, and the second driving device is used to drive the screw rod 35 to rotate, so as to realize the driving of the second slider 331 and the first slider 321 to slide synchronously;

[0052] In this embodiment, when the pressure cover 325 on the pressing assembly 32 is coaxial with the compressor on the turntable 2, the transfer mechanism 33 is located directly above the compressor on the assembly line 7, so that during the pressing process of the pressing assembly 32, the clamping claw 334 on the transfer mechanism 33 can be raised and lowered to clamp the compressor, thereby avoiding the need to drive the transfer mechanism 33 to slide after the compressor is pressed to complete the clamping of the compressor on the assembly line, thereby improving the production cycle;

[0053] In order to realize that when the pressure cover 325 on the pressing assembly 32 is coaxial with the compressor on the turntable 2, the transplanting mechanism 33 can be accurately located directly above the compressor on the assembly line 7, the distance between the first slider 321 and the second slider 331 is set to be adjustable, and this is achieved through the following structure:

[0054] A first fixing rod 335 is provided on one side of the second slider 331, and a third fixing plate 336 is fixed on the first fixing rod 335. A second fixing rod 326 is provided on one side of the first slider 321, and the second fixing rod 326 is slidably connected to the first fixing rod 335. A fourth fixing plate 327 is fixed on the second fixing rod 326. The third fixing plate 336 is threadedly connected with the first adjusting rod 34, and the end of the first adjusting rod 34 is rotatably connected to the fourth fixing plate 327. By rotating the first adjusting rod 34, the first slider 321 and the second slider 321 can be adjusted. The distance between the first and second sliders 321 and 331 can be adjusted by adjusting the distance between the first and second sliders 321 and 331, thereby realizing an adjustable fixed connection between the first and second sliders 321 and 331; when in use, the distance between the first and second sliders 321 and 331 is adjusted accordingly according to the distance between the compressor on the assembly line 7 and the compressor on the turntable 2, thereby ensuring that the transplanting component 33 and the pressing component 32 can accurately correspond to the compressor on the assembly line 7 and the compressor on the turntable 2, respectively, thereby ensuring the transplanting accuracy of the transplanting component 33 and the coaxiality of the pressure cover 325 and the compressor when the pressing component 32 is pressed.

[0055] In order to ensure that the pressing assembly 32 can complete the pressing action only when the pressure cover 325 on the pressing assembly 32 is coaxial with the compressor on the turntable 2, a second clamping mechanism 5 is provided on the mounting frame 31 to control the pressing timing of the pressing assembly 32, thereby avoiding that the pressure cover 325 is not coaxial with the compressor on the turntable 2 when the pressing assembly 32 is pressed down, resulting in failure of pressing the upper and lower covers of the compressor;

[0056] like Figure 6-8 As shown, the second engaging mechanism 5 includes a sliding rod 53, a fifth fixing plate 312 and a sixth fixing plate 313 are arranged at the upper end of the mounting frame 31, the sliding rod 53 passes through the fifth fixing plate 312 and the sixth fixing plate 313 respectively and is slidably connected with the fifth fixing plate 312 and the sixth fixing plate 313, a first baffle 531 is arranged on the sliding rod 53, the first baffle 531 is located between the fifth fixing plate 312 and the sixth fixing plate 313, a first spring 54 is installed between the sixth fixing plate 313 and the first baffle 531, two ends of the first spring 54 are respectively fixedly connected with the side surface of the sixth fixing plate 313 and the side surface of the first baffle 531, under the elastic force of the first spring 54, the first baffle 531 has a movement tendency close to the fifth fixing plate 312;

[0057] The upper end of the mounting frame 31 is rotatably connected with a rotating rod 55, and a second gear 56 is fixed on the rotating rod 55. A second rack 532 is provided on the sliding rod 53, and the second rack 532 and the second gear 56 are meshed with each other; a third rack 57 is slidably connected to the side of the second gear 56 facing away from the sliding rod 53, and the third rack 57 and the second gear 56 are meshed with each other, and one end of the third rack 57 is connected to the third fixed rod 51, and a clamping assembly 52 is fixed to the end of the third fixed rod 51, and the clamping assembly 52 includes a fourth fixed rod 521 fixedly connected to the third fixed rod 51, and the third fixed rod 51 is fixed to the end of the third fixed rod 51. The fourth fixing rod 521 is slidably connected with a second clamping plate 522, and the second clamping plate 522 can be engaged with two adjacent teeth of the first rack 322; a second spring 523 is installed between the second clamping plate 522 and the fourth fixing rod 521, and a second yielding groove 5211 is provided on the fourth fixing rod 521, and a second limiting plate 5221 is provided on the second clamping plate 522. Under the elastic force of the second spring 523, the second limiting plate 5221 can be tightly attached to the end of the second yielding groove 5211; thereby realizing an elastic connection between the second clamping plate 522 and the fourth fixing rod 521;

[0058] When the second slider 331 is not in contact with the sliding rod 53, under the elastic force of the first spring 54, the first baffle 531 is attached to the fifth fixed plate 312, and the second clamping plate 522 is engaged with the adjacent two teeth of the first rack 322, thereby preventing the pressing action of the pressing assembly 32; when the second slider 331 slides to the top of the compressor on the assembly line 7, the gland 325 is coaxial with the compressor on the turntable 2, and the second slider 331 slides with the sliding rod 53, thereby driving the second clamping plate 522 to just leave the first rack 322, and the pressing assembly 32 can perform the pressing action;

[0059] In summary, the pressing assembly 32 can only perform the pressing action when the pressure cover 325 is coaxial with the compressor on the turntable 2; and when the transplanting assembly 33 is transplanting the compressor, the second clamping plate 522 will always be engaged with the adjacent two teeth of the first rack 322, thereby preventing the pressing assembly 32 from sliding and pressing down at the same time, causing the risk of the compressor being damaged; due to the elastic connection between the second clamping plate 522 and the fourth fixing rod 521, the sliding of the pressing assembly 32 and the transplanting mechanism 33 will not be interfered;

[0060] In this embodiment, in order to ensure the accuracy of the engagement timing of the second clamping plate 522 and the first rack 322 after the distance between the first slider 321 and the second slider 331 is adjusted, the third fixed rod 51 and the third rack 57 are slidingly adjustable; the third fixed rod 51 is slidingly connected to the third rack 57, the third fixed rod 51 is fixed with a seventh fixed plate 511, the third rack 57 is fixed with an eighth fixed plate 571, the seventh fixed plate 511 is threadedly connected with a second adjusting rod 58, and the end of the second adjusting rod 58 is rotatably connected to the eighth fixed plate 571.

[0061] A first engaging mechanism 4 is installed on one side of the first rack 322, and the first engaging mechanism 4 is used to limit the running timing of the screw rod 35 to prevent the screw rod 35 from rotating during the pressing process of the pressing assembly 32, thereby causing displacement of the pressing action;

[0062] like Figure 5 As shown, the first engaging mechanism 4 includes a fifth fixing rod 41, the fifth fixing rod 41 is fixedly connected to the first rack 322, the lower end of the fifth fixing rod 41 is slidably connected to the first clamping plate 42, and the sliding direction is the vertical direction, and the lower end of the first clamping plate 42 can be clamped with the spiral groove of the screw rod 35; a third spring 43 is installed between the first clamping plate 42 and the fifth fixing rod 41, so as to realize the elastic connection between the first clamping plate 42 and the fifth fixing rod 41; a first clearance groove 411 is opened on the fifth fixing rod 41, and a first limiting plate 421 is arranged on the first clamping plate 42, and under the elastic force of the third spring 43, the first limiting plate 421 can be tightly attached to the lower end of the first clearance groove 411;

[0063] When the pressing assembly 32 is pressed down, the first clamping plate 42 can be driven to press down and engage with the spiral groove of the screw rod 35, thereby limiting the rotation of the screw rod 35. In addition, since the first clamping plate 42 and the fifth fixing rod 41 are elastically connected, when the first clamping plate 42 engages with the spiral groove of the screw rod 35, the pressing assembly 32 will not be limited from continuing to press down.

[0064] Although the second locking mechanism 5 can prevent the pressing action from being performed when the pressing component 32 slides, this will affect the operation of the pressing component 32 when an unexpected situation occurs, such as the rotation of the screw rod 35, thereby affecting the production rhythm. In order to ensure the production rhythm requirements, the first locking mechanism 4 is set to synchronously limit the rotation of the screw rod 35 when the pressing component 32 performs the pressing action, so as to avoid the occurrence of unexpected situations such as the rotation of the screw rod 35 when the pressing component 32 is pressed, thereby ensuring stable pressing while also ensuring the production rhythm.

[0065] A third clamping mechanism 6 is installed on one side of the mounting frame 31. The third clamping mechanism 6 is used to limit the rotation of the turntable 2, so that when the pressing assembly 32 performs the pressing action, the rotation of the turntable 2 is limited, thereby ensuring the stability of the pressing process;

[0066] like Figure 9-11 As shown, the third engaging mechanism 6 includes a fixing frame 61, which is fixed to one side of the mounting frame 31, and a third clamping plate 62 is slidably connected to the fixing frame 61, and the third clamping plate 62 is also slidably connected to the mounting frame 31. A third gear 22 is provided on the outer circle of the turntable 2, and one end of the third clamping plate 62 can be engaged with two adjacent teeth of the third gear 22, thereby limiting the rotation of the turntable 2;

[0067] A second baffle 621 is provided on the third clamping plate 62, and a fourth spring 63 is fixed between the side of the second baffle 621 and the side of the mounting frame 31. Under the elastic force of the fourth spring 63, the second baffle 621 can be tightly attached to the mounting frame 61, and at this time, the third clamping plate 62 is not engaged with the adjacent two teeth of the third gear 22;

[0068] The upper end of the third clamping plate 62 is provided with an arc block 622, and one side of the arc block 622 is provided with a through groove 623. A sixth fixing rod 64 is fixed on the first rack 322, and one end of the sixth fixing rod 64 is connected to the seventh fixing rod 65; when the pressing assembly 32 completes the pressing action, the first rack 322 descends to drive the seventh fixing rod 65 to descend, and the lower end of the seventh fixing rod 65 can contact the arc surface of the arc block 622 and generate an extrusion force, thereby driving the third clamping plate 62 to approach the rotating disk 2. As the seventh fixing rod 65 continues to descend, the seventh fixing rod 65 can be inserted into the through groove 623. At this time, the end of the third clamping plate 62 is engaged with the third gear 22, thereby limiting the rotational freedom of the rotating disk 2;

[0069] The lower end of the seventh fixing rod 65 is rotatably connected to a roller 652, and the roller 652 can contact the arc surface of the arc block 622, thereby reducing the friction between the seventh fixing rod 65 and the arc block 622, and ensuring the smoothness of the descent of the seventh fixing rod 65;

[0070] In this embodiment, in order to prevent the seventh fixing rod 65 from being misaligned with the arc block 622 due to the change in the position of the seventh fixing rod 65 after the distance between the first slider 321 and the second slider 331 is adjusted, the seventh fixing rod 65 and the sixth fixing rod 64 are set to be slidably adjustable to ensure that the seventh fixing rod 65 can correspond to the arc block 622;

[0071] The sixth fixing rod 64 is slidably connected to the seventh fixing rod 65, a ninth fixing plate 641 is provided on the sixth fixing rod 64, a tenth fixing plate 651 is provided on the seventh fixing rod 65, a third adjusting rod 66 is threadedly connected to the ninth fixing plate 641, and a terminal end of the third adjusting rod 66 is rotatably connected to the tenth fixing plate 651; by rotating the third adjusting rod 66, the position of the seventh fixing rod 65 can be adjusted first to avoid misalignment of the seventh fixing rod 65 and the arc block 622.

[0072] Working principle:

[0073] By arranging a pressing assembly 32 and a transplanting assembly 33 on the mounting frame 31, and arranging a fixed connection with an adjustable distance between the pressing assembly 32 and the transplanting assembly 33, it is ensured that the pressing assembly 32 and the transplanting assembly 33 correspond to the compressor on the assembly line 7 and the compressor on the turntable 2 respectively, so that during the pressing process of the pressing assembly 32, the clamping claw 334 on the transplanting mechanism 33 can be lifted and lowered to complete the clamping of the compressor, thereby improving the production cycle; by arranging a second clamping mechanism 5 on the mounting frame 31, the pressing process is controlled. The pressing timing of the component 32 ensures that the pressing component 32 can complete the pressing action only when the pressure cover 325 is coaxial with the compressor on the turntable 2, thereby preventing the pressure cover 325 from being pressed down due to the compressor being not coaxial with the turntable 2, resulting in failure in the pressing of the upper and lower covers of the compressor; by setting the first locking mechanism 4, the rotation timing of the screw rod 5 is limited, thereby preventing the screw rod 5 from rotating when the pressing component 32 is pressed down, resulting in failure in the pressing; by setting the third locking mechanism 6, it is ensured that the turntable 2 will not rotate during the pressing process, thereby ensuring the stability of the pressing.

[0074] The main function of the present invention is a compressor upper and lower cover pressing device, which improves the production rhythm by arranging a pressing assembly and a transplanting assembly on a mounting frame, avoids the pressing cover and the compressor on the turntable from being pressed down coaxially, resulting in failure of the pressing of the upper and lower covers of the compressor, and ensures the stability of the pressing process.

[0075] In summary, after reading the present invention document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of the present invention without creative mental work, which all fall within the scope of protection of the present invention.
