Description

Technical Field

[0001] This invention belongs to the field of compressor assembly, specifically a compressor thrust bearing seat ring assembly device and assembly method. Background Technology

[0002] The automotive air conditioning compressor is the heart of the automotive air conditioning refrigeration system, playing the role of compressing and transporting refrigerant vapor. Air conditioning compressors are classified according to their internal working mechanism into three types: crank-connecting rod type (composed of crank, connecting rod, piston, intake and exhaust valves, etc.); rocker plate type compressor (composed of main shaft, bevel gear, swashplate, connecting rod, piston, intake and exhaust valves, and rocker plate, etc.); and swashplate type compressor (composed of main shaft, swashplate, cylinder, piston, intake and exhaust valves, etc.). Currently, there are three main types.

[0003] A variable displacement swashplate compressor typically includes a clutch assembly, a housing, and a core mechanism housed within the housing. The core mechanism consists of a piston, a main shaft, a swashplate, and a drive disc. The main shaft thrust bearing race comprises a lower washer, a flat roller bearing, an upper washer, a disc spring, and a snap ring. Its function is to provide stable support for the main shaft and to bear and distribute axial loads, ensuring the normal operation of the compressor.

[0004] The existing thrust bearing housing consists of multiple parts, and the assembly operation is mainly carried out in steps, which results in low efficiency. Secondly, the thickness is not measured before each part is assembled, which easily leads to situations where the retaining ring cannot be installed (the overall size is too large and exceeds the installation area) or the structure cannot be realized after installation (the overall size is too small and cannot be installed properly). Summary of the Invention

[0005] The technical problem to be solved by this invention is:

[0006] To efficiently complete the assembly of compressor thrust bearing races and ensure the accuracy and reliability of the assembly process, an assembly equipment and process that can quickly complete the assembly work, ensure accuracy, and operate reliably is needed.

[0007] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention, which adopts the following technical solution:

[0008] A compressor thrust bearing race assembly device, comprising:

[0009] The feeding mechanism includes a rear selection module, a rear gripping module, and a rear thickness detection module. The rear selection module is used to select a lower pad of appropriate thickness.

The front thickness detection module is used to detect the thickness of the stacked part.

The free end of the clamping rod is movable on the guide rails, and a horizontal extension rod is provided at the bottom of the guide rails. A through pin is provided on the horizontal extension rod and inserted into the waist-shaped hole. The free end of the clamping rod is connected to a movable plate through a hinge rod, and the movable plate is slidably mounted on the fixing part.

[0014] The outer support includes a pneumatic gripper, and a movable plate is mounted on the gripping end of the pneumatic gripper.

[0015] Preferably, the positioning part has an arc-shaped surface on the side opposite to the clamping part, and the arc-shaped surface is adapted to the cylinder bore wall.

[0016] Preferably, both the rear selection module and the front selection module include a storage rack, a material column is provided on the storage rack, a horizontally movable material picking platform is provided at the bottom of the material column, and a material picking trough is provided on the material picking platform, which picks up one material at a time.

[0017] Preferably, the rear gripping module includes a second vertical linear module and a second horizontal linear module, and a second pneumatic gripper. The second pneumatic gripper is vertically mounted on the second vertical linear module, and the second vertical linear module is mounted on the second horizontal linear module.

A spring is provided between the moving frame and the detection table, and the displacement sensor is installed on the moving frame to detect the displacement of the detection table relative to the moving frame.

[0020] A method for assembling a compressor thrust bearing race, comprising the following assembly steps:

[0021] Pre-selection of materials:

[0022] The front selection module operates by using the material picking platform to pick up one of the flat bearings, upper washers, disc springs, and snap rings from the storage rack at a time.

[0023] Forward grabbing:

[0024] The front gripping module operates by moving the gripping structure above the corresponding workpiece via the horizontal linear module three, and then lowering the gripping structure via the vertical linear module three. The gripping structure grips the planar bearing and upper shim each time. After gripping, the vertical linear module three returns to its initial height. The horizontal linear module three then moves the gripping structure to the front thickness detection module. The vertical linear module three adjusts the gripping structure height and lowers the planar bearing. The vertical linear module adjusts the gripping structure and resets it. Then, the rotary cylinder operates, and the vertical linear module three adjusts the gripping structure height and lowers the upper shim. The vertical linear module adjusts the gripping structure and resets it. The horizontal linear module three, the vertical linear module three, and the gripping structure will repeat this process to complete the lowering of the disc spring and retaining spring.

[0025] Front thickness detection:

[0026] When the front thickness detection module is working, the lifting cylinder drives the moving frame to the set elevation. After the detection table contacts the snap ring, it moves upward relative to the moving frame. The displacement sensor detects the displacement of the detection table relative to the moving frame.

[0027] Post-selection materials:

[0028] The subsequent material selection module operates by retrieving the lower pads from the storage rack via the material retrieval platform, taking only one pad at a time.

[0029] Post-fetch:

[0030] The rear gripping module operates. The vertical linear module two adjusts the height of the pneumatic gripper two. After the pneumatic gripper two descends to the predetermined height, it grips the lower pad. The vertical linear module two then adjusts the pneumatic gripper two back to its initial height. The horizontal linear module two adjusts the horizontal position of the pneumatic gripper two until it is above the rear thickness detection module. The vertical linear module two adjusts the height of the pneumatic gripper two. After the pneumatic gripper two descends to the rear thickness detection module, it releases the lower pad. The vertical linear module two then adjusts the pneumatic gripper two back to its initial height. The horizontal linear module two adjusts the horizontal position of the pneumatic gripper two back to its initial position.

[0031] Post-thickness inspection:

[0032] When the thickness detection module is working, the lifting cylinder drives the moving frame to the set elevation. After the detection table contacts the snap ring, it moves upward relative to the moving frame. The displacement sensor detects the displacement of the detection table relative to the moving frame. If the detected data does not meet the set thickness requirement, the lower shim is removed and the selection is repeated until a lower shim that meets the set thickness requirement is found. The set thickness requirement is equal to the sum of the thickness value detected by the previous thickness detection and the thickness value detected by the lower shim of the material to be selected.

[0033] Post-feeding:

[0034] The rear gripping module works again. The vertical linear module two adjusts the height of the pneumatic gripper two. The pneumatic gripper two descends to the rear thickness detection module and grips the lower pad. The vertical linear module two adjusts the pneumatic gripper two back to its initial height. The horizontal linear module two adjusts the horizontal position of the pneumatic gripper two until it is above the cylinder. The vertical linear module two adjusts the height of the pneumatic gripper two. The pneumatic gripper two descends into the cylinder and releases the lower pad. The vertical linear module two adjusts the pneumatic gripper two back to its initial height. The horizontal linear module two adjusts the horizontal position of the pneumatic gripper two back to its initial position.

[0035] Pre-feeding:

[0036] When the feeding module is working, the horizontal linear module 1 adjusts the horizontal position of the feeding component to be above the front thickness detection module, and the vertical linear module 1 adjusts the height position of the feeding component. The bottom surface of the positioning part presses against the upper surface of the stacked component. At this time, the clamping short column is located in the hole of the snap ring, and the clamping end of the pneumatic gripper 1 is inserted into the interior of the stacked component.

[0037] When the pneumatic gripper is working, the external support of the gripping end fixes the planar bearing of the stacked parts, and at the same time drives the moving plate to move outward, bringing the gripping short columns closer to each other and clamping the snap ring into a state smaller than the inner hole of the cylinder.

[0038] The vertical linear module 1 readjusts the height of the feeding component to the initial height, the horizontal linear module 1 adjusts the horizontal position of the feeding component to be above the cylinder body with the lower shim installed, the vertical linear module 1 adjusts the height of the feeding component to be inside the cylinder body, and the clamping end of the pneumatic gripper 1 drives the clamping short column to release the snap ring and the plane bearing, and the snap ring is engaged in the slot on the inner wall of the cylinder body hole.

[0039] The vertical linear module 1 readjusts the height of the feeding component to the initial height, and the horizontal linear module 1 readjusts the horizontal position of the feeding component to the initial state.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] This invention employs a grouping approach. Group A consists of a planar bearing, upper shim, disc spring, and retaining ring, while Group B consists of a lower shim. Groups A and B are selected and their thicknesses are measured separately. By first determining the thickness value of Group A and then selecting the thickness value of Group B, the thickness value of Group A directly affects the bearing's assembly clearance and stability. If the thickness does not meet the requirements, it may lead to abnormal bearing operation or even damage. After the thickness values ​​of Group A and Group B meet the thickness requirements, the error range is greatly reduced due to only two measurements being performed. Furthermore, the bearing performance is guaranteed. Additionally, it eliminates the need for cumulative thickness measurements on each component (as the measurement error is similar to inaccurate superposition), resulting in high operational efficiency and precision.

[0042] This invention achieves automated assembly through a process of pre-selection, pre-thickness detection, post-selection, post-thickness detection, post-feeding, and pre-feeding (press fitting). During pre-feeding, the stacked components of group A are clamped. First, the bottom surface of the positioning part presses against the upper surface of the retaining spring, and then the stacked components are clamped. This clamping ensures the state of the stacked components. In particular, if the clamping hole at the end of the retaining spring is deformed, it is easy to cause the problem of one end being higher than the other. At the same time, the retaining spring can be directly installed in the slot without the need for a subsequent press fitting mechanism, resulting in a more compact structure.

Detailed Implementation

[0058] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0059] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0060] Example 1: A compressor thrust bearing race assembly device, comprising:

[0061] The feeding mechanism 10 includes a rear selection module 11, a rear gripping module 12, and a rear thickness detection module 13. The rear selection module 11 is used to select a lower pad of appropriate thickness, and the rear gripping module 12 is used to move the selected lower pad to the rear thickness detection module 13 and load the lower pad after the thickness detection is completed and meets the requirements into the cylinder.

[0062] The material selection mechanism 20 includes a front selection module 21, a front gripping module 22, and a front thickness detection module 23. The front selection module 21 is equipped with four parts to select a planar bearing, an upper gasket, a disc spring, and a retaining ring, respectively. The front gripping module 22 is used to stack the planar bearing, upper gasket, disc spring, and retaining ring from bottom to top at the front thickness detection module 23 to form a stacked part. The front thickness detection module 23 is used to detect the thickness of the stacked part.

[0063] The feeding module 30 moves the stacked planar bearing, upper washer, disc spring, and snap ring together into the cylinder and presses them into the cylinder.

[0064] like Figure 2 As shown, both the rear selection module 11 and the front selection module 21 include a storage rack 111. A material column 112 is mounted on the storage rack 111. A horizontally movable picking platform 113 is mounted at the bottom of the material column 112. A picking slot 114 is mounted on the picking platform 113, and the picking slot 114 picks up one material at a time. A picking bin is located at the bottom of the storage rack 111. The picking platform 113 is slidably positioned within the picking bin. A picking cylinder 115 is mounted on the picking platform 113 and is installed on the side of the storage rack 111. The picking platform 113 reciprocates under the action of the picking cylinder, and during this reciprocating motion, the picking platform remains sealed within the picking bin. When the picking slot 114 is located below the material column 112, the material will automatically fall into the picking slot 114, with only one material falling at a time, thus achieving the goal of picking only one item at a time.

[0065] like Figure 3As shown, the rear gripping module 12 includes a vertical linear module 121, a horizontal linear module 122, and a pneumatic gripper 123. The pneumatic gripper 123 is vertically mounted on the vertical linear module 121, and the vertical linear module 121 is mounted on the horizontal linear module 122. The pneumatic gripper 123 is used to grip the lower pad. The horizontal linear module 122 is used to horizontally adjust the position of the pneumatic gripper 123, and the vertical linear module 121 is used to vertically adjust the height of the pneumatic gripper 123.

[0066] The vertical pneumatic gripper 123 can be adjusted by adjusting the height of the vertical linear module 121 to achieve the gripping position adjustment of the vertical pneumatic gripper 123. The horizontal position of the pneumatic gripper 123 can be adjusted by adjusting the horizontal linear module 122 to switch back and forth between the thickness detection position, the feeding position and the picking position to meet different work needs.

[0067] like Figure 4 As shown, the front gripping module 22 includes a horizontal linear module 3 211, a vertical linear module 3 212, and a gripping structure. The horizontal linear module 3 211 is used to adjust the distance between the gripping structure and the cylinder body, and the vertical linear module 3 212 is used to adjust the vertical height of the gripping structure. The gripping structure includes a rotary cylinder 213, a pneumatic gripper 3 214, and a pneumatic gripper 4 215. The pneumatic gripper 3 214 and the pneumatic gripper 4 215 are installed at the output end of the rotary cylinder 213 and can selectively rotate by an angle. The pneumatic gripper 3 214 is used to grip the plane bearing and the upper washer, and the pneumatic gripper 4 215 is used to grip the disc spring and the snap ring.

[0068] Pneumatic grippers 214 and 215 are installed at the output end of rotary cylinder 213 to select two parts at a time. When the part is placed at the thickness detection position, it is placed one at a time and rotated 180° after each placement. The horizontal linear module 211 and the vertical linear module 212 are used to adjust the horizontal and vertical positions respectively to achieve position adjustment.

[0069] like Figure 5 As shown, both the rear thickness detection module 13 and the front thickness detection module 23 include a lifting cylinder 131, a moving frame 132, a detection table 133, a displacement sensor 134, and a detection base 136. The detection base 136 has a detection groove. The moving frame 132 is mounted on the piston rod end of the lifting cylinder 131. The detection table 133 is mounted on the moving frame 132, and the detection table 133 and the moving frame 132 are slidably coupled. A spring 135 is provided between the moving frame 132 and the detection table 133. The displacement sensor 134 is mounted on the moving frame 132 to detect the displacement of the detection table 133 relative to the moving frame 132. The two ends of the moving frame 132 are vertically slidably mounted on the frame, and the lifting cylinder 131 is fixed to the frame (the frame is not shown in the figure).

[0070] The lifting cylinder 131 drives the moving frame 132 to descend to the set elevation. The set elevation is such that when there is no material in the detection slot, the detection table 133 just touches the bottom surface of the detection slot. Since there is a material installed in the detection slot at this time, the detection table 133 will move upward relative to the moving frame 132 and compress the spring 135. The displacement sensor 134 detects the displacement change of the detection table 133, which is the thickness value of the material.

[0071] like Figure 6 As shown, the feeding module 30 includes a horizontal linear module 31 and a vertical linear module 32. The vertical linear module 32 is mounted on the horizontal linear module 31, and a feeding component 33 is mounted on the vertical linear module 32. The feeding component 33 includes a fixing part 331, a clamping part 332, an outer support part 333, and a positioning part 334. The fixing part 331 is mounted on the vertical linear module. The clamping part 332, the positioning part 334, and the outer support part 333 are all mounted on the fixing part 331. The clamping part 332 and the positioning part 334 are located on both sides of the outer support part 333. The bottom of the clamping part 332 is provided with a clamping short column 335. The distance between the two clamping short columns 335 can be selectively adjusted. The outer support part 333 is used to support and clamp the inner side of the stacked component outward. The lower surface of the positioning part 334 abuts against the top surface of the stacked component.

[0072] like Figure 7 and Figure 8 , Figure 9 , Figure 10 As shown, the clamping part 332 includes two clamping rods 336 arranged in parallel. The clamping rods 336 are provided with a waist-shaped hole 337. The fixing part 331 is provided with two downwardly extending guide rails 338. The free end of the clamping rod 336 is movable on the guide rail 338. The bottom of the guide rail 338 is provided with a horizontal extension rod 339. The horizontal extension rod 339 is provided with a through pin 3310 that passes through the waist-shaped hole 337. The free end of the clamping rod 336 is connected to a moving plate 3311 through a hinge rod. The moving plate 3311 is slidably installed on the fixing part 331.

[0073] The outer support 333 includes a pneumatic gripper, and a movable plate 3311 is mounted on the gripping end of the pneumatic gripper.

[0074] The positioning part 334 has an arc-shaped surface on the side opposite to the clamping part 332. The arc-shaped surface is adapted to the cylinder bore wall. A pressure sensor is embedded in the lower surface of the positioning part to ensure the assembly clearance and stability of the bearing.

[0075] The horizontal position and vertical height of the feeding component 33 are adjusted by the horizontal linear module 31 and the vertical linear module 32. When the feeding component 33 clamps the stacked components, the bottom surface of the positioning part 334 abuts against the upper surface of the stacked components. Then, the clamping part 332 and the outer support part 333 act simultaneously. The clamping part 332 brings the clamping holes of the snap ring closer to each other, and the outer support part 333 supports the inner ring of the plane bearing, thereby achieving clamping and fixing. Then, it is directly transported into the cylinder and press-fitted without the need for a separate press-fitting mechanism, making the overall structure more compact.

[0076] A method for assembling a compressor thrust bearing race, comprising the following assembly steps:

[0077] Pre-selection of materials:

[0078] When the front selection module 21 is working, it picks up the plane bearing, upper washer, disc spring and snap ring from the storage rack 111 through the picking platform 113. Only one item is picked up at a time.

[0079] Forward grabbing:

[0080] The front gripping module 22 operates by moving the gripping structure above the corresponding material via the horizontal linear module 3 211, and lowering the gripping structure via the vertical linear module 3 212. The gripping structure grips the planar bearing and the upper shim each time. After gripping, the vertical linear module 3 212 returns to its initial height. The horizontal linear module 3 211 moves the gripping structure to the front thickness detection module 23. Then, the vertical linear module 3 212 adjusts the height of the gripping structure and lowers the planar bearing. The vertical linear module adjusts the gripping structure and resets it. Then, the rotary cylinder 213 operates, and the vertical linear module 3 212 adjusts the height of the gripping structure and lowers the upper shim. The vertical linear module adjusts the gripping structure and resets it. The horizontal linear module 3 211, the vertical linear module 3 212, and the gripping structure will repeat the operation to complete the lowering of the disc spring and the retaining spring.

[0081] Front thickness detection:

[0082] When the front thickness detection module 23 is working, the lifting cylinder 131 drives the moving frame 132 to move to the set elevation. After the detection table 133 contacts the snap ring, it moves upward relative to the moving frame 132. The displacement sensor 134 detects the displacement of the detection table 133 relative to the moving frame 132.

[0083] Post-selection materials:

[0084] The subsequent material selection module operates by using the material picking platform 113 to pick up the lower pads on the storage rack 111, taking only one at a time.

[0085] Post-fetch:

[0086] When the rear gripping module 12 is in operation, the vertical linear module 2 121 adjusts the height of the pneumatic gripper 2 123. After the pneumatic gripper 2 123 descends to the predetermined height, it grips the lower pad. The vertical linear module 2 121 then adjusts the pneumatic gripper 2 123 back to its initial height. The horizontal linear module 2 122 adjusts the horizontal position of the pneumatic gripper 2 123 until it is above the rear thickness detection module 13. The vertical linear module 2 121 then adjusts the height of the pneumatic gripper 2 123. After the pneumatic gripper 2 123 descends to the rear thickness detection module 13, it releases the lower pad. The vertical linear module 2 121 then adjusts the pneumatic gripper 2 123 back to its initial height. The horizontal linear module 2 122 then adjusts the horizontal position of the pneumatic gripper 2 123 back to its initial height.

[0087] Post-thickness inspection:

[0088] When the rear thickness detection module 13 is working, the lifting cylinder 131 drives the moving frame 132 to move to the set elevation. After the detection table 133 contacts the snap ring, it moves upward relative to the moving frame 132. The displacement sensor 134 detects the displacement of the detection table 133 relative to the moving frame 132. If the detected data does not meet the set thickness requirement, the lower shim is removed and the selection is repeated until the lower shim meets the set thickness requirement. The set thickness requirement is equal to the sum of the thickness value detected by the front thickness detection and the thickness value detected by the lower shim of the material to be selected.

[0089] Post-feeding:

[0090] The rear gripping module 12 operates again. The vertical linear module 2 121 adjusts the height of the pneumatic gripper 2 123. The pneumatic gripper 2 123 descends to the rear thickness detection module 13 and grips the lower pad. The vertical linear module 2 121 adjusts the pneumatic gripper 2 123 back to its initial height. The horizontal linear module 2 122 adjusts the horizontal position of the pneumatic gripper 2 123 until it is above the cylinder. The vertical linear module 2 121 adjusts the height of the pneumatic gripper 2 123. The pneumatic gripper 2 123 descends into the cylinder and releases the lower pad. The vertical linear module 2 121 adjusts the pneumatic gripper 2 123 back to its initial height. The horizontal linear module 2 122 adjusts the horizontal position of the pneumatic gripper 2 123 back to its initial position.

[0091] Pre-feeding:

[0092] When the feeding module 30 is working, the horizontal linear module 31 adjusts the horizontal position of the feeding component 33 to be above the front thickness detection module 23, and the vertical linear module 32 adjusts the height position of the feeding component 33. The bottom surface of the positioning part 334 is pressed against the upper surface of the stacked component. At this time, the clamping short column 335 is located in the hole of the snap ring, and the clamping end of the pneumatic gripper 1 is inserted into the interior of the stacked component.

[0093] When the pneumatic gripper is working, the external support of the gripping end fixes the planar bearing of the stacked parts, and at the same time drives the moving plate 3311 to move outward and bring the gripping short columns 335 closer together to clamp the snap ring into a state smaller than the inner hole of the cylinder.

[0094] The vertical linear module 32 readjusts the height of the feeding component 33 to the initial height, the horizontal linear module 31 adjusts the horizontal position of the feeding component 33 to be above the cylinder body with the lower shim installed, and the vertical linear module 32 adjusts the height of the feeding component 33 to be inside the cylinder body. The clamping end of the pneumatic gripper 1 drives the clamping short column 335 to release the snap ring and the plane bearing. The snap ring is engaged in the slot on the inner wall of the cylinder body hole.

[0095] The vertical linear module 32 readjusts the height of the feeding component 33 to its initial height, and the horizontal linear module 31 readjusts the horizontal position of the feeding component 33 to its initial state.

[0096] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
