Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gap gauge placement tooling, in particular to a gap gauge placement device and a placement method and a compressor assembly system. BACKGROUND

[0002] In the manufacturing process of modern high-efficiency compressors, the assembly gap between the stator and the rotor is one of the core process parameters that determines the performance of the whole machine. The gap is usually controlled in the micron level range of 0.02 mm to 0.08 mm, and the assembly gap between the stator and the rotor directly affects the compression efficiency, volumetric efficiency, operating noise, temperature rise stability and long-term operation reliability. For example, in a scroll compressor, if the gap increases by 0.01 mm, the volumetric efficiency will decrease by about 2.3%; and if the gap is too small, the rotor and the stator are prone to friction, resulting in "sweeping" or jamming failure.

[0003] In order to realize the precise control of the assembly gap between the stator and the rotor, a gap gauge is usually used for on-site rapid detection in production. As a high-precision measuring tool, the size of the gap gauge matches the target gap, and the qualitative or semi-quantitative evaluation is realized through the "pass-fail" judgment method. However, the placement process of the gap gauge itself is a key link affecting the measurement accuracy, and in the prior art, manual operation is mainly relied on, and during the placement of the gap gauge, the following defects exist: 1. The gap gauge is easily damaged: during insertion, the end of the gap gauge collides with the rotor slot, causing the gap gauge body to be scratched and deformed, affecting subsequent reuse or measurement accuracy; 2. Poor operation consistency: different operators have different techniques, and the insertion depth, angle and force vary greatly, resulting in fluctuation of the measurement results and difficulty in achieving quality traceability; 3. Low assembly efficiency: manual operation is slow and difficult to match the pace requirements of modern automated production lines.

[0004] The placement process of the gap gauge has become a restricting factor for the assembly quality and efficiency of the compressor. SUMMARY

[0005] In order to overcome the problems in the related art, one of the purposes of the present application is to provide a gap gauge placement device, which wraps the top outer side of a first workpiece with a surrounding piece before placing the gap gauge, and then places the gap gauge on the outer side of the first workpiece guided by the surrounding piece, avoiding the collision and damage between the gap gauge and the first workpiece, prolonging the service life of the gap gauge, and realizing automatic placement of the gap gauge to meet the needs of automated production lines.

When the auxiliary traction member drives the ends of the enclosing member to extend, the enclosing member wraps the top outside of the first workpiece; when the placing tooling places the gap gauge outside the first workpiece along the outside of the enclosing member, the auxiliary driving assembly drives the auxiliary traction member and the enclosing member to move out from inside the gap gauge.

[0007] In the preferred technical solution of the present application, the bottom of the enclosing member is circular, and the cross-sectional area of the top of the enclosing member is smaller than that of the bottom of the enclosing member.

Here, the increase in the outer diameter mainly refers to the increase in the outer diameter at the position where the top is originally smaller than the outer diameter of the first workpiece, so as to move downward along the first workpiece under the driving of the auxiliary driving assembly until the gap gauge and the first workpiece are pushed out.

[0031] Embodiment 1 As shown in the drawings, the application provides a gap gauge placing device, which comprises a placing tool and an auxiliary tool arranged side by side, Figures 1-7 The auxiliary tool comprises an enclosing member 17, an auxiliary traction member and an auxiliary driving assembly, the auxiliary traction member is connected to the end of the enclosing member 17, and the auxiliary driving assembly is connected to the auxiliary traction member. When the end of the enclosing member 17 is stretched by the auxiliary traction member, the enclosing member 17 wraps the top outside of the first workpiece; when the placing tool places the gap gauge 10 outside the first workpiece along the outside of the enclosing member 17, the auxiliary driving assembly drives the auxiliary traction member and the enclosing member 17 to move out of the inside of the gap gauge 10. As shown in the drawings, the gap gauge 10 in the application comprises a gap gauge handle 11 and a gap gauge body 12, wherein the gap gauge body 12 is a collapsible structure, and the gap gauge body 12 has a preset thickness. The use method of the gap gauge 10 comprises: placing the gap gauge 10 outside the first workpiece, and then installing the second workpiece outside the gap gauge 10, so as to ensure that the gap between the first workpiece and the second workpiece is of a preset size. Since the gap gauge 10 needs to be placed close to the outside of the first workpiece, directly placing the gap gauge 10 can easily cause the gap gauge 10 to collide with the first assembly. The purpose of the application is to provide a gap gauge placing device, which avoids the collision between the gap gauge 10 and the first assembly through the auxiliary tool.

[0032] Figure 1 In actual application, when the gap gauge 10 is used in the assembly of a rotor 13 and a stator, when the end of the enclosing member 17 is stretched by the auxiliary traction member, the enclosing member 17 wraps the top outside of the rotor 13; when the placing tool places the gap gauge 10 outside the rotor 13 along the outside of the enclosing member 17, the auxiliary driving assembly drives the auxiliary traction member and the enclosing member 17 to move out of the inside of the gap gauge 10.

[0033] In actual application, when the gap gauge 10 is used in the assembly of a rotor 13 and a stator, when the end of the enclosing member 17 is stretched by the auxiliary traction member, the enclosing member 17 wraps the top outside of the rotor 13; when the placing tool places the gap gauge 10 outside the rotor 13 along the outside of the enclosing member 17, the auxiliary driving assembly drives the auxiliary traction member and the enclosing member 17 to move out of the inside of the gap gauge 10.

[0034] As shown in the drawings, the structure of the compressor pump body 8 in the application is Figure 2 ​As shown, when the gap gauge 10 is placed, the stator has not yet been assembled. After the gap gauge 10 is placed in place, the outer stator of the rotor 13 is assembled close to the gap gauge 10.

[0035] In this application, the enclosing component 17 can be brought together or dispersed under the traction of the auxiliary traction component. When the ends of the enclosing component 17 are brought together, they can wrap around the top of the first workpiece. When the ends of the enclosing component 17 are separated, the outer diameter of the enclosing component 17 increases, making it easier for the enclosing component 17 to be removed from the gap gauge 10 and the first workpiece. Specifically, the gap gauge 10 is placed by placing the tooling clamping the gap gauge handle 11 and driving the gap gauge body 12 to be placed downwards from the top of the first workpiece. When the gap gauge 10 is placed in place or descends to a safe position, i.e., a position where it will not collide with the first workpiece, the auxiliary traction component drives the ends of the enclosing component 17 to retract. At this time, the enclosing component 17 unfolds, its inner diameter increases, and it opens the gap gauge body 12. The auxiliary drive assembly drives the auxiliary traction component and the enclosing component 17 to continue moving downwards until they are separated from the gap gauge body 12. Then, the auxiliary traction component and the enclosing component 17 are driven to retreat away from the compressor pump body 8, thus separating the enclosing component 17 from the gap gauge 10.

[0036] Before placing the gap gauge 10, this application uses the enclosure 17 to wrap the top outer side of the first workpiece, and then uses the enclosure 17 as a guide to place the gap gauge 10 on the outside of the first workpiece. This avoids contact damage between the gap gauge 10 and the first workpiece, extends the service life of the gap gauge 10, and enables the automated placement of the gap gauge 10, meeting the needs of automated production lines.

[0037] Example 2 like Figures 1-7 As shown, the gap gauge placement device provided in this application includes a placement fixture and an auxiliary fixture arranged side by side. The placement fixture is used to clamp the gap gauge 10 and place it on the outside of a first workpiece. The auxiliary fixture is used to wrap the top outside of the first workpiece before placing the gap gauge 10, providing guidance for the placement of the gap gauge 10. After the gap gauge 10 is placed in a safe position, the auxiliary fixture is withdrawn from the gap gauge 10 and the first fixture.

[0038] The auxiliary tooling includes a closing component 17, an auxiliary traction component, and an auxiliary drive assembly. The auxiliary traction component is connected to the end of the closing component 17, and the auxiliary drive assembly is connected to the auxiliary traction component. When the auxiliary traction member drives the end of the enclosure member 17 to extend, the enclosure member 17 wraps around the top outer side of the first workpiece; when the placement fixture places the gap gauge 10 along the outer side of the enclosure member 17 outside the first workpiece, the auxiliary drive assembly drives the auxiliary traction member and the enclosure member 17 to move out of the gap gauge 10.

[0039] Further, the bottom of the enclosing member 17 is circular, and the top section area of the enclosing member 17 is smaller than the bottom section area of the enclosing member 17.

[0040] In the present application, the enclosing member 17 is a reverse-buckled bowl structure, which is used to provide guidance for the placement of the gap gauge 10. The gap gauge body 12 is a telescopic structure, which can be lowered to fit the enclosing member 17, so as to avoid the contact between the gap gauge body 12 and the first workpiece.

[0041] Further, the auxiliary traction member connects the two ends of the enclosing member 17 through two connecting assemblies respectively; the auxiliary traction member can drive the two connecting members to move in the direction of moving away from or moving close to each other.

[0042] The enclosing member 17 is designed to be a structure that can be assembled and disassembled, so as to facilitate the protection and guidance of the gap gauge 10 during placement, and the enclosing member 17 needs to be withdrawn from between the gap gauge 10 and the first workpiece when the gap gauge body 12 is nested outside the first workpiece. Since the enclosing member 17 can be disassembled, only the ends of the enclosing member 17 need to be separated, so as to ensure that the outer diameter of the enclosing member 17 becomes larger. Here, the outer diameter becoming larger mainly refers to the outer diameter becoming larger at the position where the top is originally smaller than the outer diameter of the first workpiece, so as to move downward along the first workpiece under the driving of the auxiliary driving assembly, until the gap gauge 10 is pushed out of the first workpiece.

[0043] Further, the connecting assembly comprises a guide connecting block 16, a guide swivel base 15 and a positioning rod 14, one end of the auxiliary traction member is connected to one end of the positioning rod 14, and the other end of the positioning rod 14 is connected to the guide connecting block 16 through the guide swivel base 15. In the present application, the auxiliary traction member can be one or two. When the auxiliary traction member is two, the two ends of the enclosing member 17 are driven to move in opposite directions by the positioning rod 14, the guide swivel base 15 and the guide connecting block 16, so as to realize the assembly and disassembly of the enclosing member 17. When the auxiliary traction member is one, the auxiliary traction member can drive the two ends of the enclosing member 17 to move in opposite directions by means of the symmetrical connecting rod structure through the positioning rod 14, the guide swivel base 15 and the guide connecting block 16. In the present application, the auxiliary traction member can drive the two positioning rods 14 to move in the direction of moving close to or moving away from each other, so as to drive the two ends of the enclosing member 17 to move away from or move close to each other through the guide swivel base 15 and the guide connecting block 16, so as to realize the assembly or disassembly.

[0044] Further, the connecting assembly further comprises an enclosing slide rail 23, the positioning rod 14 is fixed in the enclosing slide rail 23 through an enclosing slide block 22, and the enclosing slide block 22 is in sliding connection with the enclosing slide rail 23.

[0045] In this application, the enclosing slider 22 is set in the enclosing slide rail 23, and the positioning rod 14 is moved by the enclosing slider 22. This can not only ensure the smoothness of the positioning rod 14 moving in the opposite direction, but also prevent the positioning rod 14 from shifting its position when moving laterally, which would cause the ends of the enclosing member 17 to be misaligned.

[0046] Example 3 like Figures 1-7 As shown, the gap gauge placement device provided in this application includes a placement fixture and an auxiliary fixture arranged side by side. The placement fixture is used to clamp the gap gauge 10 and place it on the outside of a first workpiece. The auxiliary fixture is used to wrap the top outside of the first workpiece before placing the gap gauge 10, providing guidance for the placement of the gap gauge 10. After the gap gauge 10 is placed in a safe position, the auxiliary fixture is withdrawn from the gap gauge 10 and the first fixture.

[0047] The auxiliary tooling includes a closing component 17, an auxiliary traction component, and an auxiliary drive assembly. The auxiliary traction component is connected to the end of the closing component 17, and the auxiliary drive assembly is connected to the auxiliary traction component. When the auxiliary traction member drives the end of the enclosure member 17 to extend, the enclosure member 17 wraps around the top outer side of the first workpiece; when the placement fixture places the gap gauge 10 along the outer side of the enclosure member 17 outside the first workpiece, the auxiliary drive assembly drives the auxiliary traction member and the enclosure member 17 to move out of the gap gauge 10.

[0048] Furthermore, the first workpiece moves along the transmission line 71, and the auxiliary tooling is located on the side of the transmission line 71; The auxiliary drive assembly includes an auxiliary lifting drive 6 and a forward / backward drive 4, and the driving direction of the forward / backward drive 4 is perpendicular to both the driving direction of the lifting drive and the transmission direction of the transmission line 71; the output end of the forward / backward drive 4 is connected to the auxiliary traction component; the output end of the auxiliary lifting drive 6 is connected to the forward / backward drive 4.

[0049] When the first workpiece moves to the side of the auxiliary tool along the transmission line 71, the auxiliary tool is still away from the first workpiece, at this time, the advancing and retreating driving member 4 drives the auxiliary traction member and the enclosing member 17 to move towards the first workpiece until the enclosing member 17 is directly above the first workpiece; the auxiliary traction member is extended, when the end of the enclosing member 17 is extended by the auxiliary traction member, the enclosing member 17 forms a bowl-shaped structure capable of wrapping the top outside of the first workpiece; the auxiliary lifting driving member 6 drives the auxiliary traction member and the enclosing member 17 to descend towards the first workpiece until the enclosing member 17 wraps the top outside of the first workpiece. Through the arrangement of the advancing and retreating driving member 4 and the auxiliary lifting driving member 6, the movement of the enclosing member 17 on the top of the transmission line 71 can be ensured, and the normal operation of the transmission line 71 will not be interfered.

[0050] Further, the placing tool comprises a placing driving assembly and a clamping assembly, the output end of the placing driving assembly is connected with the clamping assembly, and the clamping assembly comprises a clamping driving member 1 and a clamping jaw 48, and the clamping driving member 1 is used to drive the clamping jaw 48 to clamp or release the gap gauge 10.

[0051] In the application, the clamping jaw 48 can be two or more, when the clamping jaw 48 is multiple, the clamping jaws 48 are evenly distributed along the edge of the clamping driving member 1 in the circumferential direction, and the clamping jaw 48 clamps or releases the handle 11 of the gap gauge under the driving of the clamping driving member 1. The placing driving assembly can drive the clamping assembly and the gap gauge 10 to move in the three-dimensional space until the gap gauge 10 is placed outside the enclosing member 17.

[0052] Further, the gap gauge 10 moves along the transmission line 71, and the placing tool is located at the side of the transmission line 71. The placing driving assembly comprises a placing lifting driving member 2 and a transverse driving member 3, the driving direction of the transverse driving member 3 is perpendicular to the driving direction of the placing lifting driving member 2, and the driving direction of the transverse driving member 3 is parallel to the transmission direction of the transmission line 71; the output end of the transverse driving member 3 is connected with the placing lifting driving member 2; and the output end of the placing lifting driving member 2 is connected with the clamping assembly.

[0053] When the gap gauge 10 moves to the placement tool side along the transmission line 71, the clamping assembly is located directly above the gap gauge 10, at this time, the placement lifting drive 2 drives the clamping assembly to descend to the position of the gap gauge 10, the clamping drive 1 drives the clamping jaw 48 to clamp the handle 11 of the gap gauge, the horizontal movement drive 3 drives the placement lifting drive 2 and the clamping assembly to move towards the position of the auxiliary tool, until the gap gauge 10 is located at the top of the enclosing part 17, and the gap gauge 10 is placed outside the first workpiece below the enclosing part 17. The placement of the gap gauge 10 outside the first workpiece below the enclosing part 17 is achieved by the horizontal movement drive 3 and the placement lifting drive 2, which can ensure the movement of the clamping assembly on the top of the transmission line 71 without interfering with the normal operation of the transmission line 71.

[0061] The gap gauge placing method provided by the embodiment includes the following steps: the auxiliary driving assembly drives the auxiliary traction member and the enclosing member 17 to move to the top outside of the first workpiece; when the auxiliary traction member drives the end of the enclosing member 17 to extend out, the enclosing member 17 encloses the first workpiece; the placing tool places the gap gauge 10 outside the first workpiece along the outside of the enclosing member 17; and the auxiliary driving assembly drives the auxiliary traction member and the enclosing member 17 to move out of the gap gauge 10.

[0062] Specifically, when the tool plate 9 moves to the side of the gap gauge placing device along the transmission line 71, that is, the enclosing member 17 and the compressor pump body 8 are aligned, the transverse driving member 3 drives the clamping assembly and the gap gauge 10 to move to the discharging waiting position which is located directly above the compressor pump body 8. The auxiliary lifting driving member 6 drives the traction driving member 5 and the enclosing member 17 to descend to the side of the compressor pump body 8, and prepares for the subsequent traction action; the advance and retreat driving member 4 drives the traction driving member 5 and the enclosing member 17 to advance towards the transmission line 71 until the enclosing member 17 is located directly above the compressor pump body 8, the traction driving member 5 is extended, drives the end of the enclosing member 17 to close, and embraces the rotor 13, at this time, the inner arc surface of the enclosing member 17 is attached to the outer wall of the rotor 13 to form a stable positioning reference.

[0063] At the same time when the enclosing member 17 is closed, the placing lifting driving member 2 is lowered to drive the clamping assembly and the gap gauge 10 to descend to directly above the enclosing member 17, at this time, the gap gauge body 12 is initially expanded by the outer wall of the enclosing member 17, and a preset gap is formed between the gap gauge body 12 and the rotor 13, the preset gap refers to the thickness of the enclosing member 17, which effectively avoids the hard collision between the gap gauge 10 and the rotor 13 in the insertion process, and significantly reduces the damage risk.

[0064] The forward driving member continues to extend and continuously pushes the enclosing member 17 to wrap the rotor 13, so that the gap gauge body 12 always maintains an open state during the descending process, and ensures that the gap gauge 10 does not contact the slot of the rotor 13, thereby fundamentally solving the problem that the gap gauge 10 is easily scratched and deformed during the placing process. When the placing lifting driving member 2 drives the gap gauge 10 to descend, the auxiliary lifting driving member 6 also synchronously drives the enclosing member 17 to descend until guiding the gap gauge 10 to descend to a safe position; the safe position refers to that the bottom of the gap gauge body 12 does not contact the components in the compressor pump body 8.

[0065] When the gap gauge 10 descends to the safe position, the traction driving member 5 is retracted, so that the end of the enclosing member 17 is separated and the inner diameter is increased, at this time, the enclosing member 17 is driven by the auxiliary lifting driving member 6 to descend until moving out of the gap gauge body 12 from below the gap gauge body 12; the advance and retreat driving member 4 drives the traction driving member 5 and the enclosing member 17 to reset.

[0066] The clamping assembly releases the gap gauge 10, and the gap gauge body 12 falls into the gap designed outside the rotor 13 under the action of gravity, and the placing process is completed. The placing lifting driving member 2 and the transverse driving member 3 drive the clamping assembly to reset, and prepare for the next cycle.

[0067] The application also provides a compressor assembling system, which comprises the gap gauge placing device as described above, and the gap gauge 10 is placed outside the rotor 13 through the gap gauge placing device as described above, so as to avoid the collision between the gap gauge 10 and the rotor 13, prolong the service life of the gap gauge 10, and realize automatic placing of the gap gauge 10, thereby improving the assembling efficiency of the rotor 13 and the stator.

[0068] The enclosing part 17 is specifically an arc-shaped tool, which realizes the positioning of the rotor 13 and the active opening of the gap gauge body 12; at the same time, the gap gauge 10 is continuously opened by the enclosing part 17 during placement, effectively avoiding the hard contact between the end of the gap gauge 10 and the rotor 13, and significantly prolonging the service life of the gap gauge 10; the driving parts in the application are cooperatively controlled through the PLC control system, ensuring the coherent action and accurate positioning, realizing the full-automatic, high-rhythm and high-consistency feeding; the modular design of the structure of the application can be integrated into the existing production line, is suitable for various types of compressors, and has good universality and popularization value.
