[0001] The invention relates to the technical field of compressors, in particular to a compressor sliding bearing press-fitting device. Background Art

[0002] In the manufacturing and maintenance process of the compressor, the installation of the sliding bearing is a key link. The accurate and efficient press-fitting of the sliding bearing has an important impact on the performance and service life of the compressor. In the traditional compressor production process, the installation of the sliding bearing usually needs to be done manually, which is not only inefficient, but also may lead to unstable installation quality due to human factors. In addition, the press-fitting process of the sliding bearing requires precise control of the force and position, otherwise it may cause damage to the bearing or other components of the compressor. Therefore, a compressor sliding bearing press-fitting device is needed.

[0003] After completing the press-fitting process, the operator of the traditional press-fitting device needs to manually remove the installed bearings. This process is not only time-consuming but also labor-intensive and inefficient. The operator performs unloading operations while the machine is running, which poses a safety risk. Since it relies on manual operation, the manual unloading and repositioning process reduces the overall production efficiency. In view of the above problems, a compressor sliding bearing press-fitting device is proposed. Summary of the invention

[0006] As mentioned above, the slot is opened at the top center of the workbench, the vertical centers of the slot, sliding rod, top block and cam coincide with each other, the clamping ring is fixed at the top center of the press-fitting slot through the slot, the driving motor and the connecting rod are rotationally connected, and the bottom outer wall of the top block is in direct contact with the contour surface of the cam.

[0007] As mentioned above, the cam forms a rotating structure with the top block through the cooperation of the connecting rod and the driving motor, and the sliding rod is slidably connected to the inner surface of the clamping ring.

[0008] As mentioned above, the surface diameters of the ejector block and the unloading push plate are both larger than the inner diameter of the clamping ring, and the unloading push plate and the ejector block are distributed at the upper and lower ends of the slide rod.

[0009] As mentioned above, the unloading push plate forms a lifting structure with the clamping ring through the cooperation of the cam and the slide rod, and the unloading push plate is set in a circular shape.

[0010] As mentioned above, the outer surface of the unloading push plate is tightly fitted with the inner wall of the top end of the slot, and the outer wall of the top end of the unloading push plate is on the same horizontal line as the press-fitting slot.

[0011] As mentioned above, a card slot is provided on the top of both sides of the workbench, a fixed block is movably connected to the inner surface of the card slot, a placement slot is provided on the top outer surface of the fixed block, a pressure ring is fixedly connected to the top inner surface of the placement slot, a guide rod is fixedly connected to the inner wall of the pressure ring, a guide sleeve is movably connected to the outer wall of the guide rod, a press head is fixedly connected to the inside of one side of the guide sleeve, and the press head is arranged directly above the press slot.

[0012] As mentioned above, the fixing block is connected to the inner wall of the slot by snapping, and two groups of guide rods are provided.

[0013] As mentioned above, the guide sleeves are symmetrically distributed on the outer walls of both sides of the press-fitting head, and the guide sleeves are directly slidably connected to the guide rods.

[0014] As mentioned above, the guide rod, guide sleeve and placement groove are symmetrically distributed on both sides of the press-fitting head and the workbench, and the press-fitting head forms a lifting structure with the press-fitting groove through the cooperation of the guide sleeve and the guide rod.

[0015] Compared with the prior art, the compressor sliding bearing press-fitting device has the following beneficial effects: When the cam is in motion, the outer surface of the cam is in direct contact with the outer wall of the bottom end of the top block, pushing the top block to move upward, and the top block drives the slide bar to slide upward in the clamping ring, and the unloading push plate at the top end of the slide bar also rises accordingly. Since the outer surface of the unloading push plate is tightly fitted with the inner wall of the top end of the slot, and the unloading push plate is circular in shape, the outer surface of the top end is on the same horizontal line with the pressing groove, so the unloading push plate will push out the pressed parts in the pressing groove during its rising process, and when the cam continues to rotate and its outline no longer pushes the top block, under the action of gravity, the unloading push plate, the slide bar and the top block descend and return to the initial position, waiting for the next unloading operation. Through the cooperation of the driving motor, cam, ejector block, slide rod and unloading push plate, the automatic unloading function after the pressing is completed is realized, which reduces manual operation and improves work efficiency. At the same time, the unloading push plate and the pressing groove are on the same horizontal line, which can smoothly push out the pressed parts to avoid damage to the parts by the device. When in use, the device can quickly and accurately complete the unloading operation of the compressor sliding bearing, greatly improving production efficiency and product quality, and reducing labor intensity and operation risks.

[0016] Second, during press-fitting, the press-fitting head moves downward along the guide rod under the action of external power, gradually approaches the sliding bearing and the compressor component, and the press-fitting head continues to descend, exerts pressure on the sliding bearing, and press-fits it onto the compressor component. During this process, the guide sleeve slides smoothly along the guide rod to ensure the verticality and stability of the press-fitting; The cooperation of the guide rod and the guide sleeve provides a stable lifting guide for the press-fitting head, ensuring the accuracy and verticality of the press-fitting and improving the press-fitting quality.

[0022] According to the overall structure of the device, the compressor component to be press-fitted is first placed in the press-fitting groove 103 of the workbench 101 at the top of the base 1, and the sliding bearing is press-fitted. Under the action of external power, the press-fitting head 306 moves downward along the guide rod 304, gradually approaching the sliding bearing and the compressor component. The press-fitting head 306 continues to descend, exerts pressure on the sliding bearing, and presses it onto the compressor component. During this process, the guide sleeve 305 slides smoothly along the guide rod 304 to ensure the verticality and stability of the press-fitting. When the press-fitting is completed, the drive motor 2 is started, and the drive motor 2 drives the connecting rod 201 to rotate, so that the cam 202 on one side of the connecting rod 201 starts to rotate. As the cam 202 rotates, its contour surface The cam 202 is in direct contact with the outer wall of the bottom end of the top block 203, pushing the top block 203 to move upward, and the top block 203 drives the slide bar 204 to slide upward in the clamping ring 205, and the unloading push plate 207 at the top of the slide bar 204 also rises accordingly. Since the outer surface of the unloading push plate 207 is tightly fitted with the inner wall of the top end of the slot 206, and the unloading push plate 207 is arranged in a circular shape, the outer part of its top end is on the same horizontal line as the press-fitting groove 103, the unloading push plate 207 will push out the pressed parts in the press-fitting groove 103 during its rising process. When the cam 202 continues to rotate and its contour no longer pushes the top block 203, under the action of gravity, the unloading push plate 207, the slide bar 204 and the top block 203 descend and return to the initial position, waiting for the next unloading operation.

[0023] like Figure 1-6 As shown, the slot 206 is opened at the top center of the workbench 101, the vertical centers of the slot 206, the slide bar 204, the top block 203 and the cam 202 coincide with each other, the clamping ring 205 is fixed to the top center of the press-fitting groove 103 through the slot 206, the driving motor 2 and the connecting rod 201 are rotatably connected, the bottom outer wall of the top block 203 is in direct contact with the contour surface of the cam 202, the cam 202 forms a rotating structure with the top block 203 through the cooperation of the connecting rod 201 and the driving motor 2, and the slide bar 204 is slidably connected to The inner surface of the clamping ring 205, the surface diameters of the top block 203 and the unloading push plate 207 are all larger than the inner diameter of the clamping ring 205. The unloading push plate 207 and the top block 203 are distributed at the upper and lower ends of the slide bar 204. The unloading push plate 207 forms a lifting structure with the clamping ring 205 through the cooperation of the cam 202 and the slide bar 204. The unloading push plate 207 is set in a circular shape. The outer surface of the unloading push plate 207 is tightly fitted with the top inner wall of the slot 206, and the top outer wall of the unloading push plate 207 is on the same horizontal line as the press-fitting groove 103.

[0024] The driving motor 2 drives the connecting rod 201 to rotate, so that the cam 202 on one side of the connecting rod 201 starts to rotate. As the cam 202 rotates, its contour surface directly contacts the outer wall of the bottom end of the top block 203, pushing the top block 203 to move upward, and the top block 203 drives the slide bar 204 to slide upward in the clamping ring 205, and the unloading push plate 207 at the top of the slide bar 204 also rises accordingly. Since the outer surface of the unloading push plate 207 is tightly fitted with the inner wall of the top end of the slot 206, and the unloading push plate 207 is set in a circular shape, the outer part of its top end is at the same horizontal line as the press-fitting groove 103, the unloading push plate 207 will push out the components pressed in the press-fitting groove 103 during its rising process. When the cam 202 continues to rotate and its contour no longer pushes the top block 203, under the action of gravity, the unloading push plate 207, the slide bar 204 and the top block 203 fall and return to the initial position to wait for the next unloading operation.

[0025] like Figure 1-6 As shown, the fixed block 301 is snap-connected to the inner wall of the slot 3, two groups of guide rods 304 are provided, the guide sleeves 305 are symmetrically distributed on the outer walls on both sides of the press-fitting head 306, the guide sleeves 305 and the guide rods 304 are directly slidably connected, the guide rods 304, the guide sleeves 305 and the placement grooves 302 are symmetrically distributed on both sides of the press-fitting head 306 and the workbench 101, and the press-fitting head 306 forms a lifting structure with the press-fitting groove 103 through the cooperation of the guide sleeves 305 and the guide rods 304.

[0026] Under the action of external power, the press-fitting head 306 moves downward along the guide rod 304, gradually approaching the sliding bearing and the compressor component. The press-fitting head 306 continues to descend, exerting pressure on the sliding bearing and press-fitting it onto the compressor component. During this process, the guide sleeve 305 slides smoothly along the guide rod 304 to ensure the verticality and stability of the press-fitting.

[0027] Working principle: When the device is used, the compressor component to be press-fitted is first placed in the press-fitting groove 103 of the workbench 101 at the top of the base 1, and the sliding bearing press-fitting operation is performed. When the press-fitting is completed, the drive motor 2 is started, and the drive motor 2 drives the connecting rod 201 to rotate, so that the cam 202 on one side of the connecting rod 201 starts to rotate. As the cam 202 rotates, its contour surface directly contacts the outer wall of the bottom end of the top block 203, pushing the top block 203 to move upward, and the top block 203 drives the slide bar 204 to slide upward in the clamping ring 205, and the slide bar 204 The unloading push plate 207 at the top of 04 also rises accordingly. Since the outer surface of the unloading push plate 207 is tightly fitted with the inner wall of the top of the slot 206, and the unloading push plate 207 is set in a circular shape, the outer part of its top is on the same horizontal line as the press-fitting slot 103, so the unloading push plate 207 will push out the pressed parts in the press-fitting slot 103 during its rising process. When the cam 202 continues to rotate and its contour no longer pushes the top block 203, under the action of gravity, the unloading push plate 207, the slide bar 204 and the top block 203 fall back to the initial position and wait for the next unloading operation. Under the action of external power, the press-fitting head 306 moves downward along the guide rod 304, gradually approaching the sliding bearing and the compressor component. The press-fitting head 306 continues to descend, exerting pressure on the sliding bearing and press-fitting it onto the compressor component. During this process, the guide sleeve 305 slides smoothly along the guide rod 304 to ensure the verticality and stability of the press-fitting.
