Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a processing equipment for a scroll compressor housing. Background Technology

[0002] A scroll compressor is a positive displacement compressor. The compression components consist of a moving scroll and a stationary scroll. It is widely used in industries such as manufacturing, agriculture, transportation, medical equipment, food decoration, and textiles, as well as other applications requiring compressed air.

[0003] During the production of the scroll compressor housing, in order to ensure the sealing of the housing joints, it is necessary to deburr the top edge and inner cavity of the housing. The traditional deburring process is to manually hold a grinder and use a rotating grinding wheel to grind along the edge of the housing. However, the grinding wheel is not convenient to extend into the inner cavity of the housing for grinding. When grinding and deburring the inner cavity of the housing, the grinding wheel needs to be replaced with a wire brush roller. The grinding wheel replacement process is cumbersome and time-consuming, which affects the processing efficiency of the scroll compressor housing. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In this embodiment, as Figure 1 and Figure 2 As shown, a scroll compressor housing processing equipment includes a bearing support 1, a two-stage grinding assembly 2, which performs deburring processing on the inner cavity and top edge of the housing at the same station to save deburring time; and a workpiece clamping assembly 3, which clamps the outer periphery or inner cavity of the housing to facilitate grinding of different positions of the housing.

[0040] The dual-stage grinding assembly 2 includes: a limiting slide shell 21, the bottom end of which is connected to the bearing support 1, and two sliding cavities 211 are formed in the limiting slide shell 21; two sliding frames 22, which are slidably connected to the two sliding cavities 211 respectively, and a guide rod 221 is connected to the top of the sliding frame 22, which is slidably connected to the limiting slide shell 21; and two drive shafts 23, which are connected to the sliding frames 22 through bearings, and a motor 231 is arranged at the top of each drive shaft 23, and a grinding disc 232 and a wire brush roller 233 are arranged at the bottom of each drive shaft 23 respectively.

[0041] As a result, the compressor housing moves to directly below the grinding disc 232, the motor 231 drives the drive shaft 23 and the grinding disc 232 to rotate, and then the guide rod 221 moves downward in the limiting slide 21. The guide rod 221 drives the sliding frame 22 to move downward along the sliding cavity 211, and the rotating grinding disc 232 contacts the top edge of the compressor housing for grinding and deburring.

[0042] The compressor housing moves to directly below the wire brush roller 233, and the motor 231 corresponding to the wire brush roller 233 is started. After the wire brush roller 233 rotates, the sliding frame 22 corresponding to the wire brush roller 233 moves downward, and the rotating wire brush roller 233 extends into the inner cavity of the compressor housing for grinding.

[0043] Specifically, the two sliding cavities 211 are symmetrically distributed based on the limiting sliding shell 21. One end of the sliding frame 22 is machined with a circular protrusion that matches the sliding cavity 211. The guide rod 221 constrains the sliding frame 22 to move only vertically within the sliding cavity 211. The motor 231 is a servo motor. The outer wall of the motor 231 is connected to the sliding frame 22. The grinding disc 232 is used to grind the top edge of the housing. The wire brush roller 233 extends into the inner cavity of the housing to grind and deburr the inner cavity of the housing.

[0044] In some embodiments, such as Figure 3 As shown, a compression spring 24 is disposed in the sliding cavity 211. The top end of the compression spring 24 is connected to the sliding frame 22, and the bottom end of the compression spring 24 abuts against the bearing support 1.

[0045] Specifically, there are two compression springs 24, which are respectively placed in two sliding cavities 211. The sliding cavities 211 constrain the compression direction of the compression springs 24, and the compression springs 24 are used to drive the sliding frame 22 to move upward along the sliding cavity 211.

[0046] In addition, the compression spring 24 can be replaced with other telescopic components.

[0047] In some embodiments, such as Figure 4 and Figure 6As shown, the workpiece clamping assembly 3 includes: a base 31, which is connected to the bottom end of the support 1; a mounting shell 32, which has a strip groove 321 on its top and is connected to the base 31 via a sliding member 34; and a double-threaded rod 33, which is connected to the mounting shell 32 via a bearing. The outer circumference of the double-threaded rod 33 is threaded with two clamping blocks 331, both of which are slidably connected to the strip groove 321.

[0048] Specifically, the base 31 is used to support the overall mechanism, and the mounting shell 32 has a cavity. The rotation of the double-threaded rod 33 drives the two clamping blocks 331 to move towards each other. The strip groove 321 is used to constrain the direction of travel of the clamping blocks 331.

[0049] It should be noted that the opposite side of the clamping block 331 is machined with a V-groove to clamp the circular compressor housing.

[0050] In some embodiments, such as Figure 6 As shown, the outer periphery of the clamping block 331 is provided with an elastic friction strip 331a, which is used to increase the friction between the clamping block 331 and the machine housing.

[0051] Specifically, the elastic friction strips 331a are made of soft rubber material, and multiple elastic friction strips 331a are provided on each clamping block 331. The elastic friction strips 331a increase the friction between the clamping block 331 and the machine housing, thereby increasing the stability of the machine housing during clamping.

[0052] In some embodiments, such as Figure 6 As shown, the input end of the double-ended threaded rod 33 is equipped with a knob 332, and the knob 332 has an internal hexagonal groove.

[0053] Specifically, rotating the knob 332 drives the double-threaded rod 33 to rotate. By creating an internal hexagonal groove in the knob 332, the knob 332 can be rotated with the aid of a hexagonal wrench.

[0054] In some embodiments, such as Figure 1 As shown, the sliding member 34 includes: two slide rails 341, the bottom ends of which are connected to the base 31; and a slide block 342, which is slidably connected to the slide rails 341 and the top of the slide block 342 is fixedly connected to the mounting shell 32.

[0055] Specifically, the two slide rails 341 are symmetrically distributed based on the slide block 342, and the mounting shell 32 and the housing are moved by moving the slide block 342.

[0056] In some embodiments, such as Figure 4 As shown, slide rail 341 is machined into a T-shape;

[0057] Specifically, the slide rail 341 is designed in a T-shape to constrain the slide block 342 to move laterally along the slide rail 341.

[0058] In some embodiments, such as Figure 5 As shown, a locating pin 343 is threadedly connected to the slide block 342, and the bottom end of the locating pin 343 abuts against the slide rail 341.

[0059] Specifically, four positioning pins 343 are designed and distributed at the four corners of the slide block 342. Threads are machined on the outer wall of the positioning pins 343. The position of the slide block 342 on the slide rail 341 is locked by the clamping force between the positioning pins 343 and the slide rail 341.

[0060] The working principle of this application is illustrated below with a preferred embodiment:

[0061] The compressor housing is placed between two clamping blocks 331. Then, the knob 332 is turned to drive the double-threaded rod 33 to rotate within the mounting housing 32. As the double-threaded rod 33 rotates, it causes the two clamping blocks 331 to move along the slot 321 towards the compressor housing, thereby clamping the compressor housing. Simultaneously, the elastic friction strip 331a deforms under force to increase the friction between the clamping blocks 331 and the compressor housing. Subsequently, the slide block 342 moves along the outer wall of the slide rail 341 to move the compressor housing to the grinding disc. Directly below 232, the position of the slide block 342 on the slide rail 341 is fixed by the positioning pin 343; then the motor 231 corresponding to the upper part of the grinding disc 232 is started. The motor 231 drives the drive shaft 23 and the grinding disc 232 to rotate. Then the guide rod 221 moves downward in the limiting slide housing 21. The guide rod 221 drives the sliding frame 22 to move downward along the sliding cavity 211. At the same time, the sliding frame 22 compresses the compression spring 24 in the sliding cavity 211. The rotating grinding disc 232 contacts the top edge of the compressor housing for grinding and deburring.

[0062] After the top edge of the compressor housing is machined, the power to the motor 231 is turned off, the grinding disc 232 stops rotating, and after the external force on the guide rod 221 is removed, the grinding disc 232 is reset under the action of the compression spring 24.

[0063] Rotate the positioning pin 343 to separate it from the slide rail 341, and continue to move the slide block 342 along the slide rail 341 until the compressor housing is moved directly below the wire brush roller 233. Then, use the positioning pin 343 to fix the position of the slide block 342 again, start the motor 231 corresponding to the wire brush roller 233, and after the wire brush roller 233 rotates, move the sliding frame 22 corresponding to the wire brush roller 233 downward. The rotating wire brush roller 233 extends into the inner cavity of the compressor housing for grinding.

[0064] In addition, the compressor housing is inverted and inserted into the outer wall of the two clamping blocks 331. The rotation of the double-ended threaded rod 33 drives the two clamping blocks 331 to move in the opposite direction. The two clamping blocks 331 and the inner wall of the compressor housing are pressed together. At this time, the closed end of the compressor housing faces upward. The closed end of the compressor housing can be polished by the rotating grinding disc 232.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
