Description

Technical Field

[0001] This utility model belongs to the technical field of molds for automated assembly of refrigeration compressor parts, specifically relating to a mold structure for automated assembly of the suction pipe of a refrigeration compressor suction muffler. Background Technology

[0002] The function of the suction silencer of a refrigeration compressor is well known. In summary, it reduces the heating effect of the refrigerant when the compressor heats up and reduces the noise and vibration caused by pressure pulsation during the refrigerant gas flow, thereby helping to reduce the operating noise of the compressor and reducing the negative impact on the compressor efficiency.

[0003] Numerous technical information related to suction silencers for refrigeration compressors can be found in publicly available Chinese patent documents. Typical examples include CN104110358A, which recommends "suction silencer and compressor having the same," and CN116006434A, which provides "suction silencer for refrigeration compressor with replaceable inlet and outlet pipes," proposed by the applicant.

[0004] With the increasing scarcity of social labor resources, rising labor costs, and the growing pursuit of manufacturing efficiency and stringent quality requirements, the traditional manual assembly method for refrigeration compressor intake mufflers is becoming increasingly incompatible with these demands. Automated assembly equipment can solve these problems. However, the intake pipe (also known as the "connecting pipe" or "air guide pipe," hereinafter the same), a key component of the refrigeration compressor intake muffler, has a relatively unique shape. Therefore, to meet the requirements of automated assembly, it needs to be supported by a reasonably structured carrier, namely a mold. Because the intake pipe, made of plastic, has a symmetrical two-part structure, in the automated assembly process, one of the two parts must first be introduced into the mold by an independent mechanism, then another mechanism will align the other part with it, followed by a pressing mechanism to press it together (so that the flange pre-set on one part and the flange hole pre-set on the other part fit together like a mortise and tenon joint), and finally, a subsequent removal mechanism will remove it from the mold.

[0005] Since the aforementioned molds fall under the category of specific tooling, and specific tooling is generally non-standard, non-standard parts refer to parts that have unique characteristics for processing and assembling a certain workpiece or product. In particular, the expected technical inspiration cannot be found in publicly available patent and non-patent documents. Therefore, they can only be designed and manufactured by the manufacturers of refrigeration compressor intake mufflers. The technical solution to be introduced below arose in this context.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural diagram of an embodiment of the present utility model; Figure 2 It is a schematic diagram of an application example of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to more clearly understand the technical essence and beneficial effects of the present utility model, the applicant will make a detailed description below in the form of embodiments. However, the description of the embodiments is not a limitation to the solution of the present utility model. Any formal but non-substantive equivalent transformation made based on the concept of the present utility model should be regarded as falling within the scope of the technical solution of the present utility model.

[0017] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back are based on the position of the figure being described and should not be construed as a specific limitation on the technical solution provided by this utility model.

[0018] Please see Figure 1 And combined Figure 2 This shows that, in its operational state, the rotary disk 1 is arranged at equal intervals along its circumference. Figure 2 The suction pipe on the rotary table 1 shown carries the mold 2.

[0019] The key technical points of the present invention are as follows: The aforementioned suction pipe support mold 2 includes a suction pipe support base 21, a support base fixing plate 22, a first end limiting block 23 for the suction pipe section, and a suction pipe section support base 24. A suction pipe support base block 211 is formed on the upward-facing side of the right end of the suction pipe support base 21. A suction pipe section end insertion notch 2111 is formed at the front end of the suction pipe support base block 211. The support base fixing plate 22 corresponds to the front side of the suction pipe support base 21 in the length direction. A suction pipe lower section wing plate adjustment slot 25 is maintained between the support base fixing plate 22 and the opposite side of the suction pipe support base 21 in the length direction. Furthermore, the support base fixing plate 22 faces the suction pipe support... A suction pipe sleeve retainer 221 is formed on the upper surface of one side of the base 21 along its length. A suction pipe sleeve end support notch 2211 is formed on the upper surface of the right end of the suction pipe sleeve retainer 221 at a position corresponding to the insertion notch 2111 at the end of the suction pipe sleeve. A first end limiting block 23 of the suction pipe sleeve is fixed to the upward-facing side of the right end of the suction pipe bearing base 21. A suction pipe sleeve mating arc cavity 231 is formed on the side of the first end limiting block 23 of the suction pipe sleeve facing the suction pipe bearing base retainer 211. A suction pipe sleeve support 24 is fixed to the upward-facing front side of the left end of the aforementioned support base fixing plate 22, and maintains a distance between it and the suction pipe sleeve retainer 221. This distance is related to the distance formed by... Figure 1 The outer diameter of the lower intake tube 20 is adapted to the schematic diagram. A first end support step 241 for the intake tube is formed on the upper rear side of the intake tube support 24, and the upper surface of the intake tube support 24 forms the first end support surface 242 for the upper intake tube.

[0020] The outward-facing four-sided surface of the aforementioned rotary table 1 constitutes the outer surface 11 of the rotary table; in the use state, the left end of the aforementioned suction pipe support base 21 and the left end of the support base fixing plate 22 protrude from the outer surface 11 of the rotary table, and the degree to which they protrude from the outer surface 11 of the rotary table is the same, while the right end of the suction pipe support base 21 and the support base fixing plate 22 is fixed to the upward-facing side of the rotary table 1.

[0021] Continue to see Figure 1 , at the right end of the aforementioned suction pipe carrier base 21, there are spaced suction pipe carrier base fixing screw holes 212. In the use state, the right end of the suction pipe carrier base 21 is fixed to the aforementioned rotary disk 1 by the suction pipe carrier base fixing screws at positions corresponding to the suction pipe carrier base fixing screw holes 212. At the right end of the aforementioned support seat fixing plate 22, there are spaced support seat fixing plate adjustment screw holes 222. In the use state, the right end of the support seat fixing plate 22 is fixed to the aforementioned rotary disk 1 by the support seat fixing plate adjustment screws at positions corresponding to the support seat fixing plate adjustment screw holes 222.

[0022] By Figure 1 As shown, the shape of the aforementioned support seat fixing plate adjustment screw hole 222 is an oval hole parallel to the short side direction of the support seat fixing plate 22, but it can also be a rectangular hole, so as to achieve the purpose of adapting the width of the suction pipe lower pipe flap adjustment slot 25 to the wall thickness of the suction pipe lower pipe flap 201 mentioned below by changing the distance between the support seat fixing plate 22 and the suction pipe carrier base 21.

[0023] On the aforementioned suction pipe flap first end limit block 23, there are a pair of suction pipe flap first end limit block screw holes 232. The suction pipe flap first end limit block 23 is fixed to the aforementioned suction pipe carrier base 21 by a pair of limit block fixing screws at positions corresponding to the pair of suction pipe flap first end limit block screw holes 232.

[0024] In this embodiment, the shape of the suction pipe flap support seat 24 is in the shape of a Chinese character 'tu' (convex), and the left end and the right end are each fixed to the support seat fixing plate 22 by a suction pipe flap support seat fixing screw 243.

[0025] Continue to see Figure 1 , for the convenience of interpreting the present utility model, in Figure 1 , there are also shown the suction pipe upper flap 30 and the suction pipe lower flap 20 that constitute the suction pipe finished product 40. The suction pipe lower flap 20 has a suction pipe lower flap wing 201, and the suction pipe upper flap 30 has a suction pipe upper flap wing 301. From Figure 1 's schematic, it can be undoubtedly determined that the aforementioned suction pipe lower flap wing 201 is inserted and mated with the aforementioned suction pipe lower flap adjustment slot 25 during the assembly process. In Figure 1 , there are also shown the lower pipe tenon 202 (also called 'flange') formed on the suction pipe lower flap 20 and the upper pipe mortise 302 (with a hole) formed on the suction pipe upper flap 30. The upper and lower pipe mortises and tenons 302, 202 are by the structural system of the automatic assembly device and by Figure 2The schematically illustrated intake pipe pressing mechanism 6 achieves a mortise and tenon fit, thus forming the intake pipe finished product 40, which can be installed into the muffler housing. Figure 1 The diagram also shows the lower tube end 203, which, during assembly, can simultaneously mate with both the insertion notch 2111 at the end of the aforementioned intake tube and the support notch 2211 at the end of the lower intake tube. Furthermore, the wing rib 2011 of the lower intake tube is also shown. The support and positioning of the upper and lower intake tubes 30 and 20 on the intake tube bearing mold 2 can be determined by… Figure 1 The illustrated state is understood as follows: for example, when the lower intake tube flange 201 is inserted into the lower intake tube flange adjustment slot 25, the portion of the lower intake tube flange 20 corresponding to the intake tube flange stop 221 abuts against, or is supported on, the intake tube flange stop 221. Since the structure of the illustrated intake tube finished product 40 is prior art, for example, references can be made to CN116006434A and CN104110358A mentioned in the background section above, etc., therefore, the applicant will not elaborate further.

[0026] Please see Figure 2The diagram shows a workbench 10, which, in use, is supported on the floor of the work area by a set (four) of support legs 108 at its bottom. A rotary table drive mechanism 101 for driving the aforementioned rotary table 1 is provided on the upper part of the workbench 10. The rotary table 1 is located above the rotary table drive mechanism 101, and its center is fixedly connected to the rotary table drive mechanism 101. The suction pipe support mold 2 of this invention consists of a set spaced around the upward-facing edge of the aforementioned rotary table 1, extending beyond the outer surface 11 of the rotary table 1. The diagram also shows a set of suction pipe support molds arranged at equal intervals in a counter-clockwise direction around the aforementioned rotary table 10, suspended above the rotary table 1. The following are provided: 1. A suction tube lower tube extraction and release mechanism 3 for releasing the extracted suction tube lower tube segment 20 onto the aforementioned suction tube support mold 2; 2. A suction tube lower tube segment missingness detection mechanism 4 for detecting whether the suction tube lower tube segment 20 is present on the suction tube support mold 2; 3. A suction tube upper tube segment extraction and release mechanism 5 for releasing the extracted suction tube upper tube segment 30 onto the suction tube support mold 2 carrying the suction tube lower tube segment 20 and aligning the suction tube upper tube segment 30 with the suction tube lower tube segment 20; 4. A suction tube upper tube segment extraction and release mechanism 6 for pressing the suction tube upper tube segment 30 and the suction tube lower tube segment 20 together. The aforementioned suction pipe pressing mechanism 6, which forms the suction pipe finished product 40 as a whole, includes a suction pipe lifting mechanism 7 for lifting the aforementioned suction pipe finished product 40 from the aforementioned suction pipe bearing mold 2 and outputting it, a retained suction pipe detection mechanism 8 for detecting whether there is a retained suction pipe 50 on the suction pipe bearing mold 2, a retained suction pipe removal mechanism 9 for removing the retained suction pipe 50 from the suction pipe bearing mold 2 and outputting it, and a retained suction pipe retention re-detection mechanism 60 for re-detecting whether there is a retained suction pipe 50 left on the suction pipe bearing mold 2.

[0027] As can be seen from the above explanation, Figure 2 The diagram shows eight workstations for the automated assembly of the finished suction tube 40. These are, in order: the workstation containing the lower suction tube segment extraction and release mechanism 3 (i.e., the corresponding workstation, hereinafter the same); the workstation containing the lower suction tube segment missing detection mechanism 4; the workstation containing the upper suction tube segment extraction and release mechanism 5; the workstation containing the suction tube pressing mechanism 6; the workstation containing the finished suction tube lifting mechanism 7; the workstation containing the retained suction tube detection mechanism 8; the workstation containing the retained suction tube removal mechanism 9; and the workstation containing the retained suction tube re-detection mechanism 60. Since there are eight workstations, the aforementioned... Figure 1 The number of suction pipe bearing modules 2 in the structure is also eight. Undoubtedly, the aforementioned rotary table 1 achieves rhythmic rotation under the control of the rotary table drive mechanism 101 by the electrical controller 70 (located on the worktable 10).

[0028] Depend on Figure 2As can be seen from the diagram, the workbench 10 has a box-shaped structure with a workbench cavity. A workbench cavity protective door 102 for opening or closing the workbench cavity is provided on the front side of the workbench 10. A main power control switch 103 is provided on the right cavity wall of the workbench cavity. An air filter device 104 for filtering the pressurized air from the pressurized air generation device is provided on the right side of the workbench cavity. A pressurized air pipeline through hole 105 is provided on the table surface of the workbench 10 for the pipeline that provides pressurized air to the working cylinder. A suction pipe finished product outlet groove 106 is provided at an inclined state on the table surface of the workbench 10, and a retained suction pipe outlet groove 107 is also provided at an inclined state, along with the retained suction pipe removal mechanism 9.

[0029] The applicant should note that the aforementioned workbench cavity shielding door 102 can also be installed on the rear side of the workbench 10, or on both the front and rear sides of the workbench 10. The aforementioned main power control switch 103 can also be installed on the left cavity wall of the workbench cavity.

[0030] Applicant combined Figures 1 to 2 Briefly describe the entire process of assembling the intake pipe of the automated intake muffler. At the station of the intake pipe lower pipe fragment extraction and release mechanism 3 (which can be called the first station), the intake pipe lower pipe fragment 20, which comes from the vibratory feeder and is input by the intake pipe lower pipe fragment input track 80a, is extracted and placed into the intake pipe carrying mold 2 on the rotary table 1. When the intake pipe carrying mold 2 on the rotary table 1, carrying the intake pipe lower pipe fragment 20, rotates to the position corresponding to the intake pipe lower pipe fragment missing detection mechanism 4, which is the second station, it performs the detection. If it is missing, the machine stops and the operator replaces it; otherwise, the rotary table 1 continues to rotate. When the suction pipe support mold 2, carrying the lower suction pipe segment 20, rotates to the position of the suction pipe upper pipe segment extraction and release mechanism 5 (which serves as the third station), the upper suction pipe segment 30, which originates from the vibratory feeder and is input via the upper suction pipe segment input track 80b, is engaged with the lower suction pipe segment 20 by the upper suction pipe segment extraction and release mechanism 5 in a manner similar to that of the lower suction pipe segment extraction and release mechanism 3. When the rotary table 1 rotates the suction pipe support mold 2, carrying the upper and lower suction pipe segments 30 and 20 in their engaged state, to the position of the suction pipe pressing mechanism 6 (which serves as the fourth station), the upper and lower suction pipe segments 30 and 20 are pressed together with a mortise and tenon-like fit to form the finished suction pipe 40. Next, when the rotary table 1 rotates the suction pipe bearing mold 2 carrying the suction pipe finished product 40 to the suction pipe finished product lifting mechanism 7, which serves as the fifth station, the suction pipe finished product 40 is extracted and released into the suction pipe finished product outlet groove 106, and then discharged from the suction pipe finished product outlet groove 106. The aforementioned upper and lower suction pipe segments 30 and 20 are obtained from the previous molding process.

[0031] Normally, the suction pipe bearing mold 2, which leaves the suction pipe finished product lifting mechanism 7 as the rotary table 1 rotates, should be in an empty mold state. The so-called empty mold state means that there are no workpieces, that is, there are no suction pipe finished products 40 that have not been removed. However, the aforementioned empty mold state cannot be absolutely or foolproofly eliminated, because in the actual use of the equipment, either of the following two situations may occur: First, the suction pipe finished product 40 is not removed; second, due to the failure of the upper and lower pipe segments 30 and 20 to connect properly or the lack of reliability in pressing them together, the suction pipe finished product lifting mechanism 7 only lifts the upper pipe segment 30, while the lower pipe segment 20 remains on the suction pipe bearing mold 2. Therefore, as the rotary table 1 rotates and rotates to the position corresponding to the sixth station where the stagnant suction pipe detection mechanism 8 is located, the stagnant suction pipe detection mechanism 8 uses the same detection principle as the aforementioned suction pipe lower tube missing detection mechanism 4 to detect whether there is a stagnant suction pipe 50, and feeds back the signal of the presence of a stagnant part to the electrical controller 70. The electrical controller 70 sends a signal to the stagnant suction pipe removal mechanism 9, which is the seventh station. When the suction pipe bearing mold 2 with the stagnant suction pipe finished product 40 or suction pipe lower tube 20 is rotated to the position of the stagnant suction pipe removal mechanism 9, the stagnant suction pipe removal mechanism 9 extracts the stagnant part on the suction pipe bearing mold 2 and releases it into the stagnant suction pipe outlet groove 107, and it is then discharged from the stagnant suction pipe outlet groove 107. As the rotary table drive mechanism 101 continues to rotate the rotary table 1, the suction pipe support mold 2, which originally corresponded to the retained suction pipe removal mechanism 9, is aligned with the position of the retained suction pipe re-detection mechanism 60, which serves as the eighth station. If there are suction pipe finished products 40 or suction pipe lower segments 20 that have not been removed by the retained suction pipe removal mechanism 9, then the retained suction pipe re-detection mechanism 60 will handle them in the same way as the aforementioned suction pipe lower segment missing detection mechanism 4, and the operator will remove the retained suction pipe from the suction pipe support mold 2. This process is repeated cyclically, and the entire equipment is operated by online operators (one person can simultaneously monitor multiple devices) by operating the corresponding buttons on the electrical controller 70. After assembly, the finished suction pipe 40 is discharged from the finished suction pipe discharge slot 106 and supplied to the subsequent process for assembly with the suction muffler housing.

[0032] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
