Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for compressor cylinder block production, specifically to an automatic testing device for compressor cylinder blocks. Background Technology

[0002] Currently, such as Figure 8 As shown, the compressor housing includes a cylinder 99, which is a cylindrical structure. The cylinder 99 has a guide hole 991 and a welding hole 992 formed on it (see Chinese Utility Model Patent Publication No. CN208793230U, "A Compressor and an Air Conditioner"). The guide hole 991 is used to weld the compressor's suction pipe. During the production process of the compressor housing, it is necessary to check whether the guide hole 991 and welding hole 992 are machined, and to inspect the machining positions of the guide hole 991 and welding hole 992. It is also necessary to inspect the inner diameter of the cylinder 99 and the welding position of the bracket 993 welded to the outer wall of the cylinder 99. If the requirements are met, subsequent processes continue; if not, the cylinder 99 needs to be reworked or scrapped. This allows for early detection of defects in the cylinder 99, avoiding wasted subsequent processes. Currently, workers use measuring tools to roughly inspect the cylinder 99, resulting in low work efficiency and requiring a high level of worker skill. Summary of the Invention

Detailed Implementation

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] The automatic compressor cylinder detection device of this utility model, such as Figure 1 and Figure 2 As shown, the automatic compressor cylinder inspection equipment of this utility model includes a support inspection station device 2, a weld hole inspection station device 3, a cylinder inner diameter inspection station device 4, and a discharge station device 5. The equipment includes a workbench with a platform 1 on it. The support inspection station device 2, weld hole inspection station device 3, cylinder inner diameter inspection station device 4, and discharge station device 5 are arranged sequentially from left to right on the platform 1. Figure 3As shown, the bracket inspection station device 2 is equipped with a guide hole inspection gauge 25 for inserting into the guide hole 991 of the inspection cylinder 99 and a bracket inspection gauge 26 for inserting into the bracket 993 on the inspection cylinder 99. Figure 13 The structure of cylinder block 99 is shown, therefore the guide hole inspection gauge 25 is cylindrical, and the bracket inspection gauge 26 can be cuboid. For example... Figures 5 to 7 As shown, the welding hole inspection station device 3 includes a guide hole positioning pin 32 for inserting into the guide hole 991 of the positioning cylinder 99 and a welding hole inspection gauge 33 for inserting into the welding hole 992 of the inspection cylinder 99. The ends of the guide hole positioning pin 32 and the guide hole inspection gauge 33 (relatively closer to the central axis of the cylinder 99) are respectively formed with guide chamfers, and the welding hole inspection gauge 33 is cylindrical. Figure 8 As shown, the cylinder inner diameter detection station device 4 includes a go / no-go gauge 41 for detecting the inner diameter of the cylinder 99. (As shown...) Figure 1 As shown, the automatic compressor cylinder detection equipment of this utility model also includes a station transfer robot 6 for sequentially transferring the cylinder 99 to the work station. That is to say, the station transfer robot 6 can transfer the cylinder 99 from left to right to the work station, so that the cylinder 99 is sequentially transferred to the bracket detection work station device 2, the welding hole detection work station device 3, the cylinder inner diameter detection work station device 4, and the discharge work station device 5.

[0028] A cylinder block conveyor line may be provided on the left side of the aforementioned workbench (the "cylinder block conveyor line" is not shown in any of the attached drawings). The station transfer robot 6 transfers the cylinder block 99 from the left side of the workbench to the right side to the support inspection station device 2. The guide hole inspection gauge 25 is first inserted into the guide hole 991 of the cylinder block 99. If the guide hole inspection gauge 25 can complete the insertion action, it is determined that the guide hole 991 exists. That is to say, if the guide hole 991 is not machined or is too small, the guide hole inspection gauge 25 will not be able to complete the insertion action of the guide hole 991. Taking the guide hole 991 as the reference, that is, the guide hole inspection gauge 25... The gauge is temporarily kept inside the conduit hole 991. Specifically, for example, in the design, the outer diameter of the conduit hole inspection gauge 25 is 0.08 mm to 0.12 mm smaller than the inner diameter of the conduit hole 991. Then, the stent inspection gauge 26 is inserted into the stent 993. If the stent inspection gauge 26 can complete the insertion action, it is determined that the position of the stent 993 relative to the conduit hole 991 is correct. That is to say, if the circumferential orientation of the stent 993 relative to the conduit hole 991 is incorrect, or if the stent 993 is welded crookedly, the stent inspection gauge 26 cannot be inserted into the bottom of the groove structure of the stent 993. After the support inspection station device 2 completes the inspection of the cylinder body 99, the station transfer robot 6 transfers the cylinder body 99 to the welding hole inspection station device 3. The guide hole positioning pin 32 is first inserted into the guide hole 991 to position the cylinder body 99 circumferentially. Then, the welding hole inspection gauge 33 is fitted and inserted into the corresponding welding hole 992. Specifically, welding holes 992 are formed in three circumferential directions of the cylinder body 99. Correspondingly, the welding hole inspection station device 3 is equipped with three welding hole inspection gauges 33. After the welding hole 992 is inspected, the station transfer robot 6 transfers the cylinder body 99 to the cylinder body inner diameter inspection station device 4, so that the go / no-go integrated gauge 41 is inserted into the cylinder body 99. After the inner diameter of the cylinder body 99 is inspected, the station transfer robot 6 transfers the cylinder body 99 to the discharge station device 5. Then, the cylinder body 99 can be removed from the automatic compressor cylinder inspection equipment of this utility model. The cylinder body 99 is quickly inspected using dedicated guide hole inspection gauge 25, bracket inspection gauge 26, weld hole inspection gauge 33, and go / no-go integrated gauge 41. This avoids workers using general measuring tools to inspect the cylinder body 99, significantly reducing inspection errors and omissions, improving inspection effectiveness and efficiency. Furthermore, the cylinder body 99 is transferred by the station transfer robot 6, reducing labor intensity.

[0029] Furthermore, such as Figure 3 and Figure 4As shown, the bracket inspection station device 2 includes a first cylinder positioning core 21 for inserting the cylinder 99 upwards, a hollow rotating platform 23 for driving the cylinder 99 to rotate horizontally, a first insertion / removal cylinder 252 for driving the guide hole inspection gauge 25 to move horizontally, a second insertion / removal cylinder 262 for driving the bracket inspection gauge 26 to move horizontally, and an alignment servo motor assembly 24. The first insertion / removal cylinder 252 drives and connects to the guide hole inspection gauge 25, the second insertion / removal cylinder 262 drives and connects to the bracket inspection gauge 26, and the alignment servo motor... The machine component 24 drives and connects to the hollow rotating platform 23. The first cylinder positioning core 21 is installed on the hollow rotating platform 23. The first cylinder positioning core 21 is correspondingly provided with a first through-beam photoelectric sensor 22 for detecting the guide hole 991 of the cylinder 99. The hollow rotating platform 23 is prior art. For example, refer to the "Hollow Rotating Platform" in Chinese Utility Model Patent Publication No. CN213176666U. The hollow rotating platform 23 is installed on the platform 1, and the alignment servo motor assembly 24 is located on the lower side of the platform 1. Figure 4 As shown, the guide hole inspection gauge 25 and the support inspection gauge 26 are horizontally slidably mounted on their respective first lifting seats. The two first lifting seats are vertically slidably mounted on the same inspection gauge support 7. The support inspection station device 2 is equipped with a first vertical adjustment screw 251 and a second vertical adjustment screw 261. The first vertical adjustment screw 251 and the second vertical adjustment screw 261 are rotatably connected to the inspection gauge support 7. The first vertical adjustment screw 251 is screwed to the first lifting seat corresponding to the guide hole inspection gauge 25, and the second vertical adjustment screw 261 is screwed to the first lifting seat corresponding to the support inspection gauge 26. The first insertion / removal cylinder 252 and the second insertion / removal cylinder 262 are respectively installed on their respective... On the first lifting seat, the piston rod of the first insertion / removal cylinder 252 is connected to the guide hole inspection gauge 25, and the piston rod of the second insertion / removal cylinder 262 is connected to the bracket inspection gauge 26. Therefore, rotating the first up / down adjustment screw 251 can drive the guide hole inspection gauge 25 to adjust up and down, and rotating the second up / down adjustment screw 261 can drive the bracket inspection gauge 26 to adjust up and down. After the adjustment is completed, for example, the inspection gauge support 7 is screwed with a screw locking screw. One end of the screw locking screw is perpendicularly pressed against the first up / down adjustment screw 251, which can lock the first up / down adjustment screw 251 in position and prevent the guide hole inspection gauge 25 from creeping up and down during operation. When the workstation transfer robot 6 aligns and lowers the cylinder body 99 onto the first cylinder body positioning core 21, the first cylinder body positioning core 21 is inserted upwards into the lower part of the cylinder body 99. A relatively large gap can exist between the first cylinder body positioning core 21 and the cylinder body 99, allowing the cylinder body 99 to easily slide onto the first cylinder body positioning core 21 by gravity. The lower end of the first cylinder body positioning core 21 has a flange portion, specifically, the flange portion contacts the lower end face of the supporting cylinder body 99. Since the first through-beam photoelectric sensor 22 is used to detect the guide hole 991, such as... Figure 2 and Figure 3 As shown, the transmitting and receiving ends of the first pair of photoelectric sensors 22 should be located on the inner and outer sides of the cylinder 99, respectively. The lower end of the cylinder 99 first triggers the first pair of photoelectric sensors 22 (the detection optical path of the first pair of photoelectric sensors 22 is blocked and disconnected by the cylinder 99). The control system senses the arrival of the cylinder 99 at the bracket detection station device 2 through the trigger signal of the first pair of photoelectric sensors 22. Then, the control system controls the alignment servo motor assembly 24 to drive the hollow rotating platform 23 to rotate horizontally. The hollow rotating platform 23 can then drive the cylinder 99 to rotate horizontally. When the guide hole 991 reaches the detection position of the first pair of photoelectric sensors 22, the detection optical path of the first pair of photoelectric sensors 22 is connected. The control system obtains the angular position of the cylinder 99 relative to the first cylinder positioning core 21 in the horizontal plane based on the connection signal of the first pair of photoelectric sensors 22. Then, the control system rotates the cylinder 99 to the position where the guide hole 991 is aligned with the guide hole detection gauge 25. The control system then... The control system controls the first insertion / removal cylinder 252 to drive the guide hole inspection gauge 25 to insert into the guide hole 991 along the radial direction of the first cylinder positioning core 21. Then, the control system controls the second insertion / removal cylinder 262 to drive the bracket inspection gauge 26 to insert into the bracket 993. Taking the first insertion / removal cylinder 252 as an example, the piston rod of the first insertion / removal cylinder 252 is equipped with magnetic switches at its extension limit position and retraction limit position, respectively. A magnet is installed on the piston of the first insertion / removal cylinder 252. When the guide hole inspection gauge 25 is inserted into the guide hole 991, the piston rod of the first insertion / removal cylinder 252 can extend to its limit position. The magnet on the piston of the first insertion / removal cylinder 252 triggers the magnetic switch corresponding to the piston rod extension limit position, so that the control system can know that the guide hole 991 is qualified through the signal of the magnetic switch. If the guide hole inspection gauge 25 is not fully inserted into the guide hole 991, the magnetic switch corresponding to the piston rod extension limit position will not be triggered. Similarly, the control system can know whether the bracket 993 is qualified. After inspection, the control system controls the first insertion / removal cylinder 252 and the second insertion / removal cylinder 262 to pull out and reset the guide hole inspection gauge 25 and the bracket inspection gauge 26, respectively. The magnetic switch corresponding to the retraction limit position of the piston rod of the first insertion / removal cylinder 252 is triggered, and the control system then controls the station transfer robot 6 to transfer the cylinder 99 to the welding hole inspection station device 3. By setting the first photoelectric sensor 22, the hollow rotary platform 23, and the alignment servo motor assembly 24, the cylinder 99 can be automatically aligned, avoiding the need for manual alignment of the cylinder 99, which is beneficial to improving work efficiency. By setting the first insertion / removal cylinder 252 and the second insertion / removal cylinder 262, the inspection process can be automated.

[0030] Furthermore, such as Figure 2 , Figures 5 to 7As shown, the welding hole detection station device 3 is equipped with a second photoelectric sensor 34 for detecting the cylinder body 99. The welding hole detection station device 3 is equipped with a second cylinder body positioning core 31 for inserting the cylinder body 99 upward relative to it, a third insertion / removal cylinder 322 for driving the guide hole positioning pin 32 to move horizontally, and a fourth insertion / removal cylinder 332 for driving the welding hole detection gauge 33 to move horizontally. The third insertion / removal cylinder 322 drives the guide hole positioning pin 32, and the fourth insertion / removal cylinder 332 drives the welding hole detection gauge 33. The guide hole positioning pin 32 and the three welding hole inspection gauges 33 are horizontally slidably mounted on the corresponding second lifting seats. The second lifting seats are vertically slidably mounted on the corresponding inspection gauge supports 7. The welding hole inspection station device 3 is provided with a third vertical adjustment screw 321 for driving the guide hole positioning pin 32 to adjust vertically and a fourth vertical adjustment screw 331 for driving the welding hole inspection gauges 33 to adjust vertically. The third vertical adjustment screw 321 and the fourth vertical adjustment screw 331 are respectively screwed to the corresponding second lifting seats. When the station transfer robot 6 aligns the cylinder 99 and lowers it onto the second cylinder positioning core 31, the cylinder 99 continues to fall into place by gravity. During this process, the cylinder 99 triggers the second photoelectric sensor 34. Based on the signal from the second photoelectric sensor 34, the control system first controls the third insertion cylinder 322 to drive the guide hole positioning pin 32 into the guide hole 991. Then, the control system controls the fourth insertion cylinder 332 to insert the welding hole inspection gauge 33 into the welding hole 992. After the inspection is completed, the welding hole inspection gauge 33 and the guide hole positioning pin 32 are pulled out and reset. The control system then controls the station transfer robot 6 to transfer the cylinder 99 to the cylinder inner diameter inspection station device 4. Through the above settings, the welding hole 992 can be automatically inspected. Moreover, by first positioning the cylinder 99 with the guide hole positioning pin 32 and then inspecting the welding hole 992, the relative position of the welding hole 992 and the guide hole 991 can be quickly checked.

[0031] Furthermore, such as Figure 8 and Figure 9 As shown, the go / no-go gauge 41 is vertically installed. The cylinder body diameter detection station device 4 is equipped with a lifting cylinder 43 and a lifting ring seat 42 for pushing the cylinder body 99 upward. The lifting ring seat 42 is sleeved on the go / no-go gauge 41, and the lifting cylinder 43 drives the lifting ring seat 42. The lifting cylinder 43 is located below the platform 1. The platform 1 is slidably connected to a lifting guide rod 44 via a linear bearing. The upper end of the lifting guide rod 44 is connected to the lifting ring seat 42. The lifting guide rod 44 passes through the platform 1, and the lower end of the lifting guide rod 44 is connected to a cylinder support plate. The lifting cylinder 43 is mounted on the aforementioned cylinder support plate, and the piston rod of the lifting cylinder 43 is connected to the platform 1. Figure 9 As shown, the upper end of the go / stop gauge 41 has a guide cone head 4101, as... Figure 8As shown, when the workstation transfer robot 6 lowers the cylinder 99 onto the upper end of the go / no-go gauge 41, the cylinder 99 continues to fall by gravity. Because the gap between the go / no-go gauge 41 and the inner wall of the cylinder 99 is small, after inspection, the control system retracts the piston rod of the lifting cylinder 43, causing the cylinder support plate to move upwards. The lifting guide rod 44 then moves the lifting ring seat 42 upwards, and the inner edge of the lifting ring seat 42 contacts the lower end face of the cylinder 99, thus pushing the cylinder 99 upwards. After moving a certain distance, the station transfer robot 6 transfers the cylinder 99 to the discharge station device 5. This shortens the working distance for the station transfer robot 6 to pull the cylinder 99 away from the go-no-go gauge 41, reducing the difficulty for the station transfer robot 6 to lift the cylinder 99. It also avoids slippage when the station transfer robot 6 moves the cylinder 99 upwards due to the tight fit between the cylinder 99 and the go-no-go gauge 41. Since the lifting ring seat 42 supports the cylinder 99 around its entire circumference, it is beneficial for the cylinder 99 to be in a balanced state.

[0032] Furthermore, such as Figure 8 and Figure 9 As shown, the cylinder inner diameter detection station device 4 is equipped with a third photoelectric sensor 45 for detecting the cylinder 99. The go / no-go integrated gauge 41 includes a go gauge part 411 and a no-go gauge part 412. The go gauge part 411 is located on the upper side of the no-go gauge part 412. The go gauge part 411, the no-go gauge part 412, and the guide cone head 4101 are arranged coaxially. The cylinder inner diameter detection station device 4 is equipped with a reflective photoelectric sensor 46 for detecting the lower end of the cylinder 99. The upper end of the no-go gauge part 412 has a clearance groove 4102 for avoiding the detection light of the reflective photoelectric sensor 46. (It should be noted that only...) Figure 8The clearance groove 4102 is schematically shown. In other words, the position of the reflective photoelectric sensor 46 corresponds to the upper end of the stop gauge part 412. With the above settings, when the station transfer robot 6 aligns and lowers the cylinder body 99 onto the go / stop gauge 41, the lower end of the cylinder body 99 first triggers the third pair of photoelectric sensors 45. The control system can then sense through the third pair of photoelectric sensors 45 that the cylinder body 99 has reached the cylinder inner diameter detection station device 4. The cylinder body 99 first fits onto the go gauge part 411 by gravity. If the inner diameter of the cylinder body 99 is qualified, since the outer diameter of the stop gauge part 412 is slightly larger than the outer diameter of the go gauge part 411, the cylinder body 99 cannot move down to fit onto the stop gauge part 412. However, at this time, the upper end of the cylinder body 99 has already passed the third pair of photoelectric sensors 45. The third pair of photoelectric sensors 45 are activated again, and the control system can determine that the cylinder body 99 can fit onto the go gauge part 411. Since cylinder 99 does not move down to the stop gauge 412, the reflective photoelectric sensor 46 will not be triggered by the lower end of cylinder 99. Instead, the detection light from the reflective photoelectric sensor 46 passes through the clearance slot 4102. Therefore, the control system can determine that cylinder 99 is not properly fitted onto the stop gauge 412 based on the non-triggered state of the reflective photoelectric sensor 46, thus determining that the inner diameter of cylinder 99 is acceptable. The control system then controls the lifting cylinder 43 to push cylinder 99 upwards a short distance (cylinder 99 is not completely detached from the stop gauge 411). If the inner diameter of cylinder 99 is too large (unacceptable), cylinder 99 will fall down onto the stop gauge 412 by gravity, and the lower end of cylinder 99 will block the triggering of the reflective photoelectric sensor 46 (located on the outside of cylinder 99). The control system can then determine that the inner diameter of cylinder 99 is unacceptable based on the activation signal of the reflective photoelectric sensor 46. Through the above settings, the inner diameter of cylinder 99 can be automatically and accurately detected.

[0033] like Figure 10 As shown, the discharge station device 5 is equipped with a discharge platform 50, a discharge photoelectric sensor 51, a longitudinal push fork 52, a longitudinal push cylinder 521, a transverse push fork 53, and a transverse push cylinder 531. The longitudinal push cylinder 521 drives the longitudinal push fork 52 to move left and right, and the transverse push cylinder 531 drives the transverse push fork 53 to move back and forth. When the inner diameter of the cylinder body 99 is detected, the station transfer robot 6 transfers the cylinder body 99 to the discharge platform 50. The cylinder body 99 triggers the discharge photoelectric sensor 51. The control system knows that the cylinder body 99 has arrived at the discharge station device 5 based on the signal from the discharge photoelectric sensor 51. The control system controls the longitudinal push cylinder 521 to drive the longitudinal push fork 52 to push the cylinder body 99 to the right. Then, the control system controls the transverse push cylinder 531 to drive the transverse push fork 53 to push the cylinder body 99 backward away from the discharge platform 50.

[0034] Furthermore, such as Figure 1 , Figure 11 and Figure 12As shown, the workstation transfer robot 6 includes a frame 60 and four sets of lifting and picking-up assemblies 61. A support column is installed on the upper side of the platform 1, and the frame 60 is installed on the upper end of the support column, thus suspending the frame 60 above the platform 1. The lifting and picking-up assembly 61 includes a lifting column 612, a lifting servo motor assembly 613, a longitudinal slide 614, and grippers 611 for holding the upper part of the cylinder 99. The grippers 611 are located at the lower end of the lifting column 612. Specifically, the grippers 611 are mounted on gripper cylinders 6110. 6110 is installed at the lower end of the lifting column 612. The lifting column 612 is slidably connected to the corresponding longitudinal slide table 614. The lifting servo motor assembly 613 drives the lifting column 612 to move up and down through a gear and rack transmission structure. The lifting servo motor assembly 613 is installed on the corresponding longitudinal slide table 614. The longitudinal slide table 614 is slidably mounted on the frame 60 through a linear guide pair. The above-mentioned "longitudinal" refers to the working position transfer direction of the cylinder 99 (i.e., the left and right direction). Therefore, the longitudinal slide table 614 can slide linearly left and right; the working position rotates... The transfer robot 6 includes a station transfer servo motor assembly 62, a ball screw pair 63, and a connecting rod 64. Adjacent longitudinal slides 614 are connected via the connecting rod 64. Specifically, rod end spherical bearings are screwed to both ends of the connecting rod 64, and the rod end spherical bearings are hinged to the corresponding longitudinal slides 614. When assembling and debugging the automatic compressor cylinder detection equipment of this utility model, the distance between adjacent longitudinal slides 614 can be adjusted. The station transfer servo motor assembly 62 is driven by the ball screw pair 63 to connect to the corresponding longitudinal slides 614. A longitudinal sliding table 614, specifically, includes a ball screw assembly 63 comprising a ball screw 631 and a nut 632. The ball screw 631 is screwed to the nut 632. The ball screw 631 is rotatably connected to a frame 60. The output shaft of the station transfer servo motor assembly 62 is connected to the left end of the ball screw 631 via a coupling. The nut 632 is mounted and fixed to the second longitudinal sliding table 614 from left to right. Thus, the station transfer servo motor assembly 62 drives four sets of lifting and picking-up assemblies 61 to move synchronously left and right. Figure 1 As shown, with the above settings, the lifting columns 612 of the four sets of lifting and picking components 61 move down, and the grippers 61 can grip the corresponding cylinders 99 respectively. Then, the lifting columns 612 of the four sets of lifting and picking components 61 rise, and the station transfer servo motor assembly 62 drives the four sets of lifting and picking components 61 to move to the right synchronously, so that the four cylinders 99 can be transferred to the corresponding next station at the same time, which is beneficial to improving work efficiency. At this time, the first cylinder positioning core 21, the second cylinder positioning core 31 and the go / stop integrated gauge 41 are coaxially aligned with the corresponding cylinders 99. Then, the lifting columns 612 move down, and the grippers 61 release the cylinders 99. After that, the control system controls the lifting servo motor assembly 613 to drive each lifting column 612 to move up and reset. The control system controls the station transfer servo motor assembly 62 to drive the four sets of lifting and picking components 61 to move to the left and reset synchronously, waiting for the next instruction to pick up the cylinder 99.
