Description

Technical Field

[0001] The invention relates to the field of spindle processing equipment, and in particular to an eccentric spindle processing equipment for a scroll air compressor and a processing method thereof. Background Art

[0002] The eccentric main shaft of the scroll air compressor is an important working part of the scroll air compressor. For example, the oil-free scroll air compressor main shaft described in patent CN208169322U is composed of an eccentric shaft and a counterweight block that are fastened and assembled through side hole structures on both sides. In the processing steps of the eccentric main shaft of the scroll air compressor, it is necessary to drill horizontal holes and vertical holes on the eccentric shaft and the counterweight block to be assembled, so that the horizontal holes on the eccentric shaft and the vertical holes on the counterweight block are connected. The conventional drilling method is to first drill horizontal holes on the eccentric shaft, and then assemble the eccentric shaft and the counterweight block together, and drill vertical hole structures on the eccentric shaft and the counterweight block, which respectively penetrate the eccentric shaft and the counterweight block and connect the horizontal holes, effectively ensuring that the vertical holes on the eccentric shaft and the vertical holes on the counterweight block have a high degree of overlap.

[0003] However, in the drilling step, since it is necessary to drill deep vertical holes in the eccentric shaft and the counterweight, the coolant sprayed on the drill bit is difficult to penetrate into the vertical holes of the eccentric shaft and the counterweight with the drill bit. Therefore, in the later stage of drilling the vertical holes in the eccentric shaft and the counterweight, the cooling effect of the sprayed liquid on the drill bit is significantly reduced, resulting in a decrease in the drilling accuracy of the drill bit, causing the drilled vertical hole to be offset, which not only increases the offset between the drilled vertical hole and the horizontal hole, but also affects the overall center of gravity distribution of the counterweight, affecting the working stability of the eccentric spindle during high-speed rotation. Summary of the invention

[0004] In order to overcome the disadvantage that the coolant sprayed on the drill bit is difficult to penetrate into the vertical holes of the eccentric shaft and the counterweight block with the drill bit, causing the drilled vertical holes to deviate and affecting the working stability of the eccentric main shaft obtained by the processing, the present invention provides an eccentric main shaft processing equipment and a processing method for a scroll air compressor.

DETAILED DESCRIPTION

[0037] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0038] A method for machining an eccentric main shaft of a scroll air compressor comprises the following steps:

[0045] like Figure 6 As shown, the left and right sides of the fixed cylinder 3 are each slidably connected with an anti-skid clamping block 31; two hydraulic rods 32 are respectively fixedly connected between the two anti-skid clamping blocks 31 and the fixed cylinder 3, and the hydraulic rods 32 provide the anti-skid clamping blocks 31 with clamping force on the eccentric shaft 81.

[0046] like Figure 6 As shown, two insertion rods 44 are welded to the rear side of the retaining ring 43, and the retaining ring 43 connects the counterweight 82 and the eccentric shaft 81 together through the insertion rods 44; a plurality of magnets 45 are fixed to the rear side of the retaining ring 43, and the retaining ring 43 stably magnetically attracts the counterweight 82 through the magnets 45.

[0047] like Figure 3 and Figure 5 As shown, the rotating mechanism includes an annular frame 12, an annular slider 21, a gear ring 22, a driving motor 23 and a spur gear 24; the annular frame 12 is bolted to the rear side of the base frame 11; the annular slider 21 is slidably connected inside the annular frame 12; the gear ring 22 is bolted to the front side of the annular slider 21; the driving motor 23 is bolted to the base frame 11; the output shaft of the driving motor 23 is fixedly connected to the spur gear 24; the spur gear 24 is meshed with the gear ring 22.

[0048] like Figure 3 and Figure 4As shown, the lifting mechanism includes a vertical rail frame 51, an electric control screw rod 52, a lifting slider 53 and a fixed frame 54; the middle part of the base frame 11 is bolted to the vertical rail frame 51; an electric control screw rod 52 is installed on the left and right sides of the vertical rail frame 51; a lifting slider 53 is slidably connected to the left and right sides of the vertical rail frame 51; the two lifting sliders 53 are respectively connected to the two electric control screw rods 52; the two lifting sliders 53 are commonly bolted to the fixed frame 54; the upper side of the fixed frame 54 is installed with an electric control fine drill rod 61; the lower side of the fixed frame 54 is installed with a vertical electric control rough drill rod 62.

[0049] The horizontal hole drilling work of the eccentric spindle processing equipment of the scroll air compressor:

[0050] First, the electric push rod 42 pushes the installation slider 41 to drive the clamping ring 43 to move forward and away from the fixed cylinder 3. The operator inserts the eccentric shaft 81 into the fixed cylinder 3. At the same time, the hydraulic rod 32 applies a clamping force to the eccentric shaft 81 to the anti-slip clamp 31. The operator then clamps the counterweight 82 in the clamping ring 43. The two insertion rods 44 on the rear side of the clamping ring 43 respectively penetrate the two side jack structures of the counterweight 82, and the magnet 45 stably magnetically attracts the counterweight 82 to the clamping ring 43. Then the electric push rod 42 pushes the installation slider 41 to drive the clamping ring 43 to move backward and reset. Figure 5 As shown, the counterweight 82 in the retaining ring 43 is sleeved on the front end of the eccentric shaft 81, and the rear ends of the two insertion rods 44 on the rear side of the retaining ring 43 are respectively inserted into the two side plug-in structures of the eccentric shaft 81, and the eccentric shaft 81 and the counterweight 82 are limitedly spliced ​​together through the insertion rods 44 to prevent the eccentric shaft 81 and the counterweight 82 from being vibrated and offset from each other during the drilling work, thereby completing the splicing work of the eccentric shaft 81 and the counterweight 82.

[0051] Afterwards, the transverse drilling mechanism drills a transverse hole at the front end of the eccentric shaft body 81. At the same time, the transverse drilling mechanism sprays spray liquid on the drilling components to cool down the drilling components of the transverse drilling mechanism in time. After the transverse hole structure is drilled at the front end of the eccentric shaft body 81, the transverse drilling mechanism leaves the transverse hole of the eccentric shaft body 81.

[0052] Fine vertical hole drilling work of this scroll air compressor eccentric spindle processing equipment:

[0053] After completing the horizontal hole drilling work of the eccentric shaft 81, the electric push rod 42 pushes the installation slider 41 to drive the retaining ring 43 to move forward again away from the fixed tube 3, and the retaining ring 43 drives the counterweight block 82 forward away from the eccentric shaft 81, so that the front end of the eccentric shaft 81 is exposed under the electric-controlled fine drill rod 61, and then the electric-controlled screw rod 52 drives the lifting slider 53 to move downward, and the lifting slider 53 drives the electric-controlled fine drill rod 61 and the vertical electric-controlled rough drill rod 62 connected to the fixing frame 54 to move downward, and the electric-controlled fine drill rod 61 drills a fine vertical hole structure connected to the horizontal hole on the upper side of the front end of the eccentric shaft 81 to complete the fine vertical hole drilling work of the eccentric shaft 81, and the electric-controlled screw rod 52 drives the lifting slider 53 to move upward, and the lifting slider 53 drives the electric-controlled fine drill rod 61 and the vertical electric-controlled rough drill rod 62 connected to the fixing frame 54 to move upward and reset.

[0054] Then the electric push rod 42 pushes the installation slider 41 to drive the clamping ring 43 to move backward and reset again, so that the eccentric shaft 81 and the counterweight block 82 are spliced ​​together again, and then the electric control screw rod 52 drives the lifting slider 53 to move downward, and the lifting slider 53 drives the electric control fine drill rod 61 and the vertical electric control rough drill rod 62 connected to the fixing frame 54 to move downward, and the electric control fine drill rod 61 drills a fine vertical hole structure on the upper side of the counterweight block 82, and the fine vertical hole of the counterweight block 82 is connected to the fine vertical hole on the eccentric shaft 81, as shown in FIG. Fig. 9 As shown, the fine vertical hole drilling work of the counterweight block 82 is completed, the electric control screw rod 52 drives the lifting slider 53 to move upward, and the lifting slider 53 drives the electric control fine drill rod 61 and the vertical electric control rough drill rod 62 connected to the fixing frame 54 to move upward and reset.

[0055] When the electric-controlled fine drill rod 61 is drilling fine vertical holes on the eccentric shaft 81 and the counterweight block 82 in succession, even if the electric-controlled fine drill rod 61 is slightly offset when drilling, resulting in the fine vertical holes on the eccentric shaft 81 and the counterweight block 82 not being completely aligned, the size of the fine vertical holes drilled on the eccentric shaft 81 and the counterweight block 82 is much smaller than the size of the vertical holes that need to be drilled on the eccentric shaft 81 and the counterweight block 82, and therefore will not cause structural damage to the vertical holes drilled on the eccentric shaft 81 and the counterweight block 82 later.

[0056] Vertical hole drilling work of this scroll air compressor eccentric spindle processing equipment:

[0057] After completing the drilling of the fine vertical holes of the eccentric shaft 81 and the counterweight 82, the output shaft of the drive motor 23 drives the spur gear 24 to rotate, and the spur gear 24 engages with the gear ring 22 to drive the annular slider 21 and the fixed cylinder 3 connected to it to rotate one hundred and eighty degrees. The fixed cylinder 3 drives the eccentric shaft 81 and the counterweight 82 to rotate one hundred and eighty degrees, so that the fine vertical holes of the eccentric shaft 81 and the counterweight 82 face downward and are vertically electrically controlled to the rough drill rod 62.

[0058] Afterwards, the electric-controlled screw rod 52 drives the lifting slide block 53 to move upward, and the lifting slide block 53 drives the electric-controlled fine drill rod 61 and the vertical electric-controlled rough drill rod 62 connected to the fixing frame 54 to move upward. The vertical electric-controlled rough drill rod 62 synchronously expands the vertical hole of the eccentric shaft body 81 and the counterweight block 82 on the basis of the fine vertical hole of the eccentric shaft body 81 and the counterweight block 82. At the same time, the horizontal drilling mechanism sprays spray liquid to the horizontal hole of the eccentric shaft body 81, and the spray liquid falls on the vertical electric-controlled rough drill rod 62 through the fine vertical holes of the eccentric shaft body 81 and the counterweight block 82, so as to cool down the vertical electric-controlled rough drill rod 62 in time, and obtain a complete vertical hole structure connected to the horizontal hole of the eccentric shaft body 81 through drilling on the eccentric shaft body 81 and the counterweight block 82, as shown in FIG. Fig.10 and Fig.11 As shown, the vertical hole drilling work of the eccentric shaft body 81 and the counterweight block 82 is completed.

[0059] The spray liquid that flows downward along the thin vertical hole cools down the vertical electric-controlled rough drill rod 62. At the same time, the spray liquid that flows downward effectively rinses the surface of the vertical electric-controlled rough drill rod 62. At the same time, the flowing spray liquid washes away the debris left on the surface of the vertical electric-controlled rough drill rod 62 during the drilling process, thereby reducing the friction resistance encountered by the vertical electric-controlled rough drill rod 62 during the drilling process, and further improving the work efficiency of the vertical electric-controlled rough drill rod 62 in drilling vertical holes on the eccentric shaft 81 and the counterweight block 82. Example

[0060] This embodiment is a further optimization based on embodiment 1. Figure 1-Figure 8 As shown, the transverse drilling mechanism includes a transverse rail frame 71, an electric slider frame 72, a transverse electric-controlled rough drill rod 73 and a spray assembly; the front side of the base frame 11 is bolted to the transverse rail frame 71; the electric slider frame 72 is slidably connected to the transverse rail frame 71; the middle part of the electric slider frame 72 is bolted to the transverse electric-controlled rough drill rod 73 for drilling a transverse hole backward at the front end of the eccentric shaft body 81; the upper side of the electric slider frame 72 is connected to the spray assembly, which sprays spray liquid to the transverse electric-controlled rough drill rod 73 and the transverse hole at the front end of the eccentric shaft body 81 in turn.

[0061] like Figure 7 and Figure 8 As shown, the spray assembly includes a telescopic rod 74, a spray head 75 and a spring 76; the telescopic rod 74 is fixedly connected to the upper side of the electric slider frame 72; the telescopic end of the telescopic rod 74 is bolted to the spray head 75, and the spray head 75 is located on the rear side of the horizontal electric-controlled rough drill rod 73; a spring 76 is fixedly connected between the spray head 75 and the fixed end of the telescopic rod 74, and the spring 76 is sleeved on the outer surface of the telescopic rod 74; the upper end of the spray head 75 is connected to a liquid inlet pipe 751, and an external spray liquid delivery device is connected to the liquid inlet pipe 751 through a pipeline, and the external spray liquid delivery device delivers spray liquid to the spray head 75 through the liquid inlet pipe 751.

[0062] During the horizontal hole drilling work on the eccentric shaft 81, the electric slide frame 72 drives the horizontal electric control rough drill rod 73 and the spray assembly to move backward along the cross rail frame 71. After the spray head 75 moves backward and close to the eccentric shaft 81, the electric slide frame 72 continues to drive the horizontal electric control rough drill rod 73 to move backward. The electric slide frame 72 pushes the telescopic rod 74 to drive the spring 76 to compress. At the same time, the horizontal electric control rough drill rod 73 drills the horizontal hole at the front end of the eccentric shaft 81 backward, and the external spray liquid delivery equipment delivers spray liquid to the spray head 75 through the liquid inlet pipe 751. The spray head 75 sprays the spray liquid on the horizontal electric control rough drill rod 73 for cooling and reducing the temperature, so that a horizontal hole structure is drilled at the front end of the eccentric shaft 81, and the drilled horizontal hole is located below the axis of the front end of the eccentric shaft 81.

[0063] After that, the electric slide frame 72 drives the horizontal electric control rough drill rod 73 and the spray assembly to move forward and reset along the horizontal rail frame 71, and the compressed spring 76 drives the telescopic rod 74 to pop out. After completing the drilling of the fine vertical hole of the eccentric shaft body 81 and the counterweight block 82, the output shaft of the drive motor 23 drives the spur gear 24 to rotate, allowing the fixed cylinder 3 to drive the eccentric shaft body 81 and the counterweight block 82 to rotate 180 degrees. The fine vertical holes of the eccentric shaft body 81 and the counterweight block 82 face downward and are vertically aligned with the electric control rough drill rod 62. The drilled horizontal hole is located at the position after the flip. Above the axis center of the front end of the eccentric shaft 81, the electric slider frame 72 then drives the horizontal electric-controlled rough drill rod 73 and the spray assembly to move backward again along the horizontal rail frame 71, so that the spray head 75 is inserted backward into the horizontal hole of the eccentric shaft 81. When the vertical electric-controlled rough drill rod 62 performs vertical hole drilling on the eccentric shaft 81 and the counterweight block 82, the spray head 75 sprays spray liquid into the horizontal hole. The spray liquid in the horizontal hole falls downward along the fine vertical holes of the eccentric shaft 81 and the counterweight block 82 onto the vertical electric-controlled rough drill rod 62 to cool it down. Example

[0064] This embodiment is a further optimization based on embodiment 2. Figure 1-Figure 8 As shown, the spray head 75 is configured as an inclined structure with its opening facing rearward and downward. When the spray head 75 is located outside the eccentric shaft 81, the spray head 75 sprays spray liquid to the transverse electrically controlled rough drill rod 73. When the spray head 75 is inserted into the eccentric shaft 81, the spray head 75 directly sprays the spray liquid into the vertical hole of the eccentric shaft 81. A suction cup 77 is fixedly connected to the spray head 75. After the spray head 75 is inserted into the horizontal hole in the eccentric shaft 81, the suction cup 77 is tightly attached to the front end of the eccentric shaft 81 to prevent a large amount of spray liquid from leaking out.

[0065] When the transverse electric-controlled rough drill rod 73 performs horizontal hole drilling on the eccentric shaft 81 , the spray head 75 is closely attached to the front end of the eccentric shaft 81 , and the spray head 75 directly sprays spray liquid on the transverse electric-controlled rough drill rod 73 through the inclined opening structure, and the spray liquid cools the transverse electric-controlled rough drill rod 73 .

[0066] When the vertical electric-controlled rough drill rod 62 performs vertical hole drilling on the eccentric shaft 81 and the counterweight 82, the spray head 75 is inserted into the transverse hole of the eccentric shaft 81, and the suction cup 77 is tightly attached to the front end of the eccentric shaft 81. The spray head 75 sprays the spray liquid directly in the direction of the fine vertical hole through the inclined opening structure. At this time, the suction cup 77 closes the transverse hole of the eccentric shaft 81, so that the transverse hole is filled with the spray liquid and the spray liquid is prevented from leaking out of the transverse hole. The initial spray liquid can only flush the vertical electric-controlled rough drill rod 62 through the fine vertical hole, thereby improving the flushing and cooling effect and surface debris cleaning effect of the vertical electric-controlled rough drill rod 62.

[0067] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
