Description

Technical Field

[0001] This invention relates to the technical field of compressor production lines, and particularly to a copper tube insertion mechanism for a compressor housing. Background Technology

[0002] Currently, on compressor production lines, the insertion of copper tubes and rubber sleeves into the compressor housing is poorly executed, resulting in a high product defect rate. The current compressor production line directly inserts the copper tubes in one step. Since the compressor housing contains a pump body, if the fitting precision of the copper tubes is not high or the insertion pressure is too high, the pump body's center position will be deflected, leading to poor pump performance. Therefore, the current compressor production line needs further improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a copper tube insertion mechanism for a compressor housing with good copper tube insertion effect.

[0004] The objective of this invention is achieved as follows:

[0005] A copper tube insertion mechanism for a compressor housing includes a tube insertion seat, a tube insertion lifting motor, a tube insertion lifting base, a tube insertion translation motor, a tube insertion translation base, a tube insertion rotation motor, a tube insertion rotation arm, and a copper tube insertion assembly. The tube insertion seat is mounted on a frame. The tube insertion lifting base is slidably mounted on the tube insertion seat. The tube insertion lifting motor is mounted on the tube insertion seat and drives the tube insertion lifting base to slide up and down. The tube insertion translation base is slidably mounted on the tube insertion lifting base. The tube insertion translation motor is mounted on the tube insertion lifting base and drives the tube insertion translation base to slide horizontally. The tube insertion rotation arm is vertically rotatably mounted on the tube insertion translation base. The tube insertion rotation motor is mounted on the tube insertion translation base and drives the tube insertion rotation arm to rotate vertically. The copper tube insertion assembly is mounted on the tube insertion rotation arm. The copper tube insertion assembly of the present invention is used to clamp copper tubes. The present invention realizes the lifting, translation and rotation of the copper tube insertion assembly through a copper tube lifting motor, a copper tube lifting seat, a copper tube translation motor, a copper tube translation seat, a copper tube rotation motor and a copper tube rotation arm, thereby allowing the copper tube to be inserted into the tube body of the housing. The copper tube insertion assembly then intermittently drives the copper tube to be inserted into the tube body until the copper tube reaches the set tube body depth.

[0006] The present invention can be further improved in the following ways.

[0007] The copper tube insertion assembly includes an insertion sliding seat, an insertion striking cylinder, an insertion translation cylinder, and an insertion clamping cylinder. The insertion sliding seat is slidably mounted at the front end of the insertion rotating arm. The insertion translation cylinder is mounted on the insertion rotating arm and drives the insertion sliding seat to slide. The insertion striking cylinder is mounted on the insertion rotating arm and located behind the insertion sliding seat. The insertion clamping cylinder is mounted on the insertion sliding seat. The insertion striking cylinder intermittently strikes the insertion sliding seat, causing the insertion sliding seat and the insertion clamping cylinder to move forward a set distance, thereby gradually inserting the copper tube into the tube body. This insertion method of the present invention does not cause the pump body inside the housing to become eccentric, and the insertion effect of the copper tube is good.

[0008] The insertion cannula sliding seat is equipped with an insertion cannula mounting seat, and the insertion cannula clamp cylinder is equipped with a cylinder fixing seat. A rear cover is fixedly connected to the rear of the insertion cannula mounting seat. The insertion cannula mounting seat has a rear-open conical channel. The rear cover is located at the rear of the insertion cannula mounting seat. A movable conical seat, a return spring, and a sliding block are located within the conical channel. The outer wall of the movable conical seat is conically fitted with the inner wall of the conical channel. The sliding block is movably disposed within the conical channel. The return spring is located between the movable conical seat and the sliding block. The front end of the movable conical seat extends out of the insertion cannula mounting seat and is fixedly connected to the cylinder fixing seat. A top shaft is located on the back of the sliding block. A clearance hole is provided on the rear cover corresponding to the position of the top shaft. The top shaft extends out of the conical channel through the clearance hole. The insertion cannula striking cylinder intermittently strikes the top shaft. The top shaft drives the sliding block, the insertion cannula mounting seat, and the insertion cannula sliding seat to slide forward, thereby moving the insertion cannula.

[0009] The gripper cylinder slides forward, intermittently inserting the copper tube into the tube body until the copper tube reaches the set depth. Furthermore, the movable conical seat can rotate 360° freely within the conical channel. The height of the insertion gripper cylinder and the copper tube can be adjusted to match the height of the tube body, correcting the center of the copper tube and ensuring alignment with the center of the tube body for better insertion results.

[0010] The insertion and striking cylinder is located behind the rear cover, and the cylinder rod of the insertion and striking cylinder is directly opposite the top shaft.

[0011] The beneficial effects of this invention are as follows:

[0012] The copper tube insertion assembly of the present invention is used to clamp copper tubes. The present invention realizes the lifting, translation and rotation of the copper tube insertion assembly through a copper tube lifting motor, a copper tube lifting seat, a copper tube translation motor, a copper tube translation seat, a copper tube rotation motor and a copper tube rotation arm, thereby allowing the copper tube to be inserted into the tube body of the housing. The copper tube insertion assembly then intermittently drives the copper tube to be inserted into the tube body until the copper tube reaches the set tube body depth.

[0013] The insertion cylinder intermittently strikes the insertion sliding seat, causing the insertion sliding seat and the insertion clamp cylinder to move forward a set distance, thereby gradually inserting the copper tube into the tube body. With this insertion method, the pump body inside the housing will not be eccentric, and the insertion effect of the copper tube is good. Attached Figure Description

[0044] The insertion tube sliding seat 210 is provided with an insertion tube mounting seat 214, and the insertion tube clamp cylinder 211 is provided with a cylinder fixing seat 220. A rear cover 215 is fixedly connected to the rear of the insertion tube mounting seat 214. The insertion tube mounting seat 214 has a conical channel 219 with an open rear. The rear cover 215 covers the rear of the insertion tube mounting seat 214. A movable conical seat 213, a return spring 216, and a sliding block 217 are provided in the conical channel 219.

The back of the sliding block 217 is provided with a top shaft 218, and the rear cover 215 is provided with a clearance hole 221 corresponding to the position of the top shaft 218. The top shaft 218 extends out of the conical channel 219 through the clearance hole 221. The insertion tube striking cylinder intermittently strikes the top shaft, which drives the sliding block, the insertion tube mounting seat, and the insertion tube sliding seat to slide forward, thereby driving the insertion tube clamping cylinder to slide forward, thus realizing the intermittent insertion of the copper tube into the tube body until the copper tube reaches the set tube depth. Furthermore, the movable conical seat can rotate freely 360° within the conical channel, and the height of the insertion clamp cylinder and the copper tube can be adjusted to match the height of the tube body to correct the center of the copper tube and keep the center of the copper tube aligned with the center of the tube body, so as to improve the insertion effect of the copper tube.

[0049] The structure of the second housing alignment mechanism 7 is the same as that of the first housing alignment mechanism 6. The first housing alignment mechanism 6 includes a support frame 61 and an alignment gripper cylinder 62 mounted on the support frame 61. The alignment gripper cylinder 62 is provided with a left gripper arm 63 and a right gripper arm 64. The alignment gripper cylinder 62 drives the left gripper arm 63 and the right gripper arm 64 to rotate open or close.

[0050] The first housing side pressure mechanism 12 and the second housing side pressure mechanism 13 both include a side pressure cylinder 14 and a top pressure block 15 disposed on the cylinder rod of the side pressure cylinder 14.

[0051] The present invention also includes a base 232, a copper tube insertion mechanism 2 and a rubber sleeve insertion mechanism 3 respectively disposed on the left and right sides of the base 232. A rubber sleeve insertion seat 30 and a tube insertion seat 20 are respectively disposed on the left and right sides of the base 232.

[0052] The housing feeding line 1 is equipped with copper tube insertion station and rubber sleeve insertion station respectively, corresponding to copper tube insertion mechanism 2 and rubber sleeve insertion mechanism 3. The copper tube insertion mechanism and rubber sleeve insertion mechanism are respectively located at the copper tube insertion station and rubber sleeve insertion station. Both the copper tube insertion station and the rubber sleeve insertion station are equipped with tooling positioning mechanisms.

[0053] The working principle of this invention is:

[0054] The feeding fixture 11 on the housing feeding line 1 transports the two housings 8 to the corresponding copper tube insertion station. Then, the fixture positioning mechanism on the copper tube insertion station lifts and positions the feeding fixture 11. At this time, the tube body 80 of the housing 8 faces the copper tube insertion mechanism 2.

[0055] Then, the copper tube supply mechanism 4 and the copper tube insertion mechanism 2 start together. The copper tube vibrating feeder 49 starts to vibrate and convey the copper tube 81. The copper tube 81 is conveyed to the copper tube discharge trough 46. The copper tube distribution motor 41 drives the copper tube distribution slide 42 and the two copper tube distribution blocks 43 to slide horizontally back and forth so that the copper tube discharge trough 46 can successively convey the copper tube 81 to the copper tube distribution trough 44 of the two copper tube distribution blocks 43. Then, the insertion lifting motor 21 drives the insertion lifting seat 22 to descend, the insertion translation motor 24 drives the insertion translation seat 23 to slide horizontally backward, and the insertion rotation motor 25 drives the insertion rotation arm 26 to rotate downward by 90°. The two insertion clamping claw cylinders 211 respectively clamp the two copper tubes 81.

[0056] Then, the first housing alignment mechanism 6 is activated, and the alignment gripper cylinder 62 drives the left gripper arm 63 and the right gripper arm 64 to rotate and close. The left gripper arm 63 and the right gripper arm 64 align and maintain the position of the tube body 80 of the housing 8 with the position of the copper tube 81. Then, the side pressure cylinder 14 of the first housing side pressure mechanism 12 drives the top pressure block 15 to press the housing 8 on the feeding fixture 11.

[0057] Subsequently, the insertion rotation motor 25 drives the insertion rotation arm 26 to rotate upward by 90°, keeping the insertion rotation arm 26, the copper tube assembly 27, and the copper tube horizontal. Then, the insertion lifting motor 21 drives the insertion lifting seat 22 to rise until the height of the copper tube 81 is consistent with the height of the tube body 80 of the housing 8. Next, the insertion translation motor 24 drives the insertion translation seat 23 to slide horizontally forward until the copper tube 81 is close to the tube body 80. The insertion translation cylinder 28 drives the insertion sliding seat 210, the insertion clamp cylinder 211, and the copper tube 81 to slide horizontally forward by 2mm, inserting the copper tube 81 into the tube body 80 by 2mm. Then, the insertion translation cylinder 28 releases the insertion sliding seat 210, and the insertion translation cylinder 28 moves the insertion sliding seat 210 forward. When 210 loses thrust, the insertion cannula translation motor 24 drives the insertion cannula translation seat 23, the insertion cannula striking cylinder 29, and the insertion cannula translation cylinder 28 to slide forward horizontally by 2mm. The insertion cannula sliding seat 210, the insertion cannula clamping cylinder 211, and the copper tube 81 remain stationary, and the depth of the copper tube 81 inserted into the tube body 80 remains unchanged. Then, the insertion cannula striking cylinder 29 starts and strikes the top shaft 218, which in turn drives the insertion cannula sliding seat 210, the insertion cannula clamping cylinder 211, and the copper tube 81 to slide forward by 2mm. This process is repeated to control the insertion cannula translation seat 23 to move forward and the insertion cannula striking cylinder 29 to strike until the depth of the copper tube 81 inserted into the tube body 80 meets the requirements. After the copper tube 81 is inserted, all the components of the copper tube insertion mechanism 2 return to their original positions to prepare for the next insertion of the copper tube 81. The copper tube insertion mechanism 2 then grabs the next copper tube 81. The tooling positioning mechanism and the first housing side pressing mechanism 12 release the feeding tooling 11, and the housing conveyor line drives the feeding tooling 11 to continue flowing downward.

[0058] When the housing conveyor line transports the feeding fixture 11 with the inserted copper tube 81 to the rubber sleeve insertion station, the fixture positioning mechanism at the rubber sleeve insertion station lifts and positions the feeding fixture 11. Then, the rubber sleeve supply mechanism 5 and the rubber sleeve insertion mechanism 3 start together, and the rubber sleeve vibrating feeder begins to vibrate and convey the rubber sleeve 82. The rubber sleeve 82 is conveyed onto the rubber sleeve discharge chute 56. The rubber sleeve forward and backward translation motor 57 drives the rubber sleeve distribution lifting cylinder 511 to move forward and backward. The rubber sleeve distribution lifting cylinder 511 drives the rubber sleeve distribution gripper cylinder 510 to lift and lower, and the rubber sleeve distribution gripper cylinder 510 grips the material. The rubber sleeve 82 on the rubber sleeve distribution groove is driven by the rubber sleeve left and right translation motor 51 to slide the rubber sleeve distribution slide 52 and the two rubber sleeve distribution blocks 53 horizontally back and forth, so that the rubber sleeve distribution gripper cylinder 510 can place the rubber sleeve 82 on the rubber sleeve positioning groove 54 of the two rubber sleeve distribution blocks 53. Then, the rubber sleeve lifting motor drives the rubber sleeve lifting seat to descend, the rubber sleeve translation motor drives the rubber sleeve translation seat to slide horizontally backward, and the rubber sleeve rotation motor drives the rubber sleeve rotation arm to rotate downward by 90°. The two rubber sleeve suction seats 37 respectively pick up the two rubber sleeves 82 on the two rubber sleeve positioning grooves 54.

[0059] Simultaneously, the second housing alignment mechanism 7 is activated, and the alignment gripper cylinder 62 drives the left gripper arm 63 and the right gripper arm 64 to close, aligning the position of the tube body 80 of the housing 8 with the position of the rubber sleeve 82. Then, the alignment gripper cylinder 62 drives the left gripper arm 63 and the right gripper arm 64 to open. Following this, the side pressure cylinder 14 of the second housing side pressure mechanism 13 drives the top pressure block 15 to press against the housing 8 on the feeding fixture 11.

[0060] Then, the rubber sleeve rotary motor drives the rubber sleeve rotating arm to rotate upward by 90°, so that the rubber sleeve rotating arm, the rubber sleeve suction seat 37 and the rubber sleeve pressing cylinder 38 remain horizontal. Then, the rubber sleeve lifting motor drives the rubber sleeve lifting seat to rise until the height of the rubber sleeve 82 is consistent with the height of the tube body 80 of the housing 8. Then, the rubber sleeve translation motor drives the rubber sleeve translation seat to slide horizontally forward. The rubber sleeve suction seat 37 moves forward with the rubber sleeve 82 until the rubber sleeve 82 is inserted into the outer wall of the tube body 80.

[0061] Then, the sleeve insertion lifting motor 31 drives the sleeve insertion lifting seat 32 to descend until the height of the air rod of the sleeve pressing cylinder 38 is consistent with the height of the sleeve 82 on the housing 8. Then, the sleeve pressing cylinder 38 drives its air rod to strike the sleeve 82 so that the sleeve 82 is completely fitted onto the tube 80 of the housing 8. After the sleeve 82 is struck, all the components of the sleeve insertion mechanism 3 return to their original positions to prepare for the next sleeve insertion. The sleeve insertion mechanism 3 picks up the next sleeve 82 again. The tooling positioning mechanism and the second housing side pressing mechanism 13 release the feeding tooling 11. The housing conveyor line drives the feeding tooling 11 to continue to flow downward. Thus, the present invention completes the work of inserting the copper tube 81 and the sleeve 82 into the housing 8.
