A compressor front end plate assembly clamping device

Abstract

This invention relates to the field of equipment technology for fastening, specifically to a compressor front-end plate assembly clamping device, including an assembly line, a tooling fixing plate, a positioning fixture, a clamping assembly, and a lifting device. The clamping assembly includes a drive mechanism, a partition plate, a pressure block, a support frame, a U-shaped photoelectric proximity switch, a spring, a ejector pin, and a sensing plate. The rotating body assembly and the front-end plate assembly are mounted on the positioning fixture. When the assembly line is started, the rotating body assembly and the front-end plate assembly are brought under the pressure block and lifted by the lifting device. The drive mechanism drives the pressure block to press down, and the protrusion of the front-end plate assembly lifts the ejector pin, causing the sensing plate to move upward. The U-shaped photoelectric proximity switch senses the sensing plate, indicating that the assembly direction is correct, and the pressure block continues to press down. If the assembly direction is incorrect, the protrusion will not reach the ejector pin, the U-shaped photoelectric proximity switch will not sense the sensing plate, and the pressure block will stop pressing down, thereby avoiding clamping assembly errors.

Description

Technical Field

[0001] This invention relates to the field of equipment technology for fastening, and more particularly to a compressor front end plate assembly clamping device. Background Technology

[0002] The clamping assembly of the front-end plate assembly and the rotating body assembly involves interlocking the round and flat pins of the front-end plate assembly with the corresponding pin holes on the rotating body assembly. During clamping, it is crucial to ensure that the oil holes in both the front-end plate assembly and the rotating body assembly are unobstructed; that is, the round pins of the front-end plate assembly must be aligned with the pin holes on the rotating body assembly. The positioning pins in the rotating body assembly positioning fixture of the general-purpose compressor on the production line ensure the orientation of the oil holes after assembly. During clamping, the orientation of the front-end plate's convex bulge is used to determine the assembly direction, ensuring correct clamping and orientation of the two components to achieve unobstructed oil passages. The clamping assembly is performed manually by tapping the front-end plate assembly and the rotating body assembly together, and visually marking the alignment with lines to confirm the correctness of the assembly direction.

[0003] However, using the above method, which involves manually determining the assembly direction and then manually tightening it, can easily lead to misjudgment of the assembly direction, ultimately resulting in incorrect tightening and assembly, which affects product quality. Summary of the Invention

[0004] The purpose of this invention is to provide a compressor front panel assembly clamping device that can avoid clamping assembly errors.

[0005] To achieve the above objectives, the present invention provides a compressor front end plate assembly clamping device, including an assembly line, a tooling fixing plate, a positioning fixture, a clamping assembly, and a lifting device. The tooling fixing plate is disposed on the assembly line, and the positioning fixture is disposed on the tooling fixing plate. The clamping assembly includes a drive mechanism, a partition, a pressure block, a support frame, a U-shaped photoelectric proximity switch, a spring, a ejector pin, and a sensing plate. The drive mechanism is disposed at the top of the assembly line, the partition is disposed on the drive mechanism, the pressure block is fixedly connected to the partition and located at the bottom of the partition, the support frame is fixedly connected to the partition and located at the top of the partition, the U-shaped photoelectric proximity switch is disposed on the support frame, the spring is disposed inside the pressure block, the ejector pin is slidably connected to the pressure block and fixedly connected to the spring, and passes through the partition, the sensing plate is fixedly connected to the ejector pin and located at the top of the ejector pin, and the lifting device is disposed inside the assembly line and located directly below the pressure block.

[0006] The drive mechanism includes two profile mounting plates, two supporting profiles, a top plate, two linear bearings, two optical axes, a cylinder, and a floating joint. The two profile mounting plates are fixedly connected to the assembly line and are located at the top of the assembly line. The two supporting profiles are fixedly connected to the two profile mounting plates and are located at the top of the two profile mounting plates. The top plate is fixedly connected to the two supporting profiles and is located at the top of the two supporting profiles. The two linear bearings are respectively disposed on the top plate. The two optical axes are slidably connected to the two linear bearings and are fixedly connected to the partition plates and pass through the two linear bearings. The cylinder is fixedly connected to the top plate and is located at the top of the top plate. The floating joint is fixedly connected to the piston rod of the cylinder and is fixedly connected to the partition plates and is located at the top of the partition plates.

[0007] The compressor front end plate assembly clamping device further includes two photoelectric sensors, which are respectively disposed on the side of the assembly line near the supporting profile.

[0008] The compressor front end plate assembly clamping device also includes a detection photoelectric sensor, which is located on the side of the assembly line near the lifting equipment.

[0009] The positioning fixture has a positioning pin, which is located on one side of the positioning fixture.

[0010] This invention discloses a compressor front-end plate assembly clamping device. The assembly line is equipped with a tooling fixing plate, which can be moved. The tooling fixing plate is used to install a positioning fixture. The positioning fixture sequentially installs a rotating body assembly and a front-end plate assembly from bottom to top. A clamping assembly cooperates with a lifting device to clamp the front-end plate assembly and the rotating body assembly. A drive mechanism is located directly above the lifting device and is used to drive a partition plate, thereby moving the pressure block up and down to achieve the clamping action. During operation, the rotating body assembly and the front-end plate assembly are installed on the positioning fixture from bottom to top. The pin of the front-end plate assembly is inserted into the pin hole of the rotating body assembly. Then, the assembly line is started, and the tooling fixing plate brings the rotating body assembly and the front-end plate assembly together to below the pressure block. The lifting device then... The tooling fixing plate is lifted, causing the rotating body assembly and the front end plate assembly to move upward. The drive mechanism drives the pressure block to press down, and the protrusion on the front end plate assembly lifts the ejector pin. The ejector pin compresses the spring and moves upward, causing the sensing plate to move upward and enter the U-shaped photoelectric proximity switch. The U-shaped photoelectric proximity switch senses the sensing plate, indicating that the assembly direction of the front end plate assembly is correct. The drive mechanism continues to drive the pressure block to press down, completing the clamping assembly. After the clamping assembly is completed, the spring drives the ejector pin to reset, and the lifting device drives the tooling fixing plate to move downward and reset. If the assembly direction is reversed, the protrusion will not reach the ejector pin, the ejector pin will not move the sensing plate upward enough, the U-shaped photoelectric proximity switch will not sense the sensing plate, and the drive mechanism will stop, thus avoiding clamping assembly errors.

Detailed Implementation

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] Please see Figures 1 to 10 The present invention provides a compressor front end plate assembly clamping device:

[0025] The assembly line 101 includes a tooling fixing plate 102, a positioning fixture 103, a clamping assembly 104, and a lifting device 105. The tooling fixing plate 102 is mounted on the assembly line 101, and the positioning fixture 103 is mounted on the tooling fixing plate 102. The clamping assembly 104 includes a drive mechanism 106, a partition 107, a pressure block 108, a support frame 109, a U-shaped photoelectric proximity switch 110, a spring 111, a ejector pin 112, and a sensing plate 113. The drive mechanism 106 is located at the top of the assembly line 101, and the partition 107 is mounted on the drive mechanism 106. The pressure block 108 is connected to the partition 109. Plate 107 is fixedly connected and located at the bottom of partition 107. Support frame 109 is fixedly connected to partition 107 and located at the top of partition 107. U-shaped photoelectric proximity switch 110 is disposed on support frame 109. Spring 111 is disposed inside pressure block 108. Ejector pin 112 is slidably connected to pressure block 108 and fixedly connected to spring 111, and passes through partition 107. Sensing plate 113 is fixedly connected to ejector pin 112 and located at the top of ejector pin 112. Lifting device 105 is disposed inside assembly line 101 and located directly below pressure block 108.

[0026] In this embodiment, the assembly line 101, the tooling fixing plate 102, the positioning tooling 103, and the lifting device 105 are all existing technologies and will not be described in detail here. The front end plate assembly 201 and the rotating body assembly 301 are assembled by interfering with the round pin 203 and the flat pin of the front end plate assembly 201 and the two pin holes at corresponding positions on the rotating body assembly 301. When the round pin 203 is aligned, the flat pin is naturally aligned as well. The tooling fixing plate 102 is provided on the assembly line 101 and can be moved. The tooling fixing plate 102 is used to install the positioning tooling 103. The positioning tooling 103 is used to install the rotating body assembly from bottom to top. The front plate assembly 201 and the rotating body assembly 301 are assembled together with the lifting device 105. The clamping assembly 104 is used to cooperate with the lifting device 105 to clamp and assemble the front plate assembly 201 and the rotating body assembly 301. The driving mechanism 106 is located directly above the lifting device 105 and is used to drive the partition 107, thereby driving the pressure block 108 to move up and down to achieve the clamping action. During operation, the rotating body assembly 301 and the front plate assembly 201 are installed on the positioning fixture 103 from bottom to top. The round pin 203 of the front plate assembly 201 is inserted into the round pin hole 302 of the rotating body assembly 301 through the chamfered guide. Then the assembly line 101 is started, and the rotating body assembly 301 and the front plate assembly 201 are clamped together by the fixture fixing plate 102. The front-end plate assembly 201 is brought together below the pressure block 108. The lifting device 105 lifts the tooling fixing plate 102. The positioning tooling 103 drives the rotating body assembly 301 and the front-end plate assembly 201 to move upward. The driving mechanism 106 drives the pressure block 108 to press down. The protrusion 202 on the front-end plate assembly 201 lifts the ejector pin 112. The ejector pin 112 compresses the spring 111 and moves upward, driving the sensing plate 113 to move upward and into the U-shaped photoelectric proximity switch 110. The U-shaped photoelectric proximity switch 110 senses the sensing plate 113, indicating that the assembly direction of the front-end plate assembly 201 is correct. The driving mechanism 106 continues to drive the... The pressure block 108 presses down to complete the clamping assembly. After the clamping assembly is completed, the spring 111 drives the ejector pin 112 to reset, the lifting device 105 drives the tooling fixing plate 102 to move down and reset, and the positioning tooling 103 drives the rotating body assembly 301 and the front end plate assembly 201 to move down and reset as well, and are sent away by the assembly line 101. If the assembly direction is reversed, the protrusion 202 will not hit the ejector pin 112, the ejector pin 112 will not drive the sensing plate 113 to move up high enough, the U-shaped photoelectric proximity switch 110 will not sense the sensing plate 113, the drive mechanism 106 will stop and issue an alarm, thereby avoiding clamping assembly errors.

[0027] Furthermore, the drive mechanism 106 includes two profile mounting plates 114, two supporting profiles 115, a top plate 116, two linear bearings 117, two optical shafts 118, a cylinder 119, and a floating joint 120. The two profile mounting plates 114 are respectively fixedly connected to the assembly line 101 and are located at the top of the assembly line 101. The two supporting profiles 115 are respectively fixedly connected to the two profile mounting plates 114 and are located at the top of the two profile mounting plates 114. The top plate 116 is respectively connected to the two supporting profiles 117. 5. A fixed connection is established and located on the top of the two supporting profiles 115. Two linear bearings 117 are respectively disposed on the top plate 116. Two optical axes 118 are slidably connected to the two linear bearings 117 and fixedly connected to the partition plate 107 respectively, and pass through the two linear bearings 117 respectively. A cylinder 119 is fixedly connected to the top plate 116 and located on the top of the top plate 116. A floating joint 120 is fixedly connected to the piston rod of the cylinder 119 and fixedly connected to the partition plate 107, and located on the top of the partition plate 107.

[0028] In this embodiment, two profile mounting plates 114 are used to install two supporting profiles 115. The two supporting profiles 115 support the top plate 116. Two linear bearings 117 are provided on the top plate 116 for slidingly mounting two optical axes 118. The two optical axes 118 support the partition 107, thereby supporting the pressure block 108. The floating joint 120 connects the piston rod of the cylinder 119 to the partition 107. When the pressure block 108 needs to be pressed down, the cylinder 119 is activated, and the cylinder 119 pushes the partition 107. The partition 107 drives the pressure block 108 to press down, realizing the pressing action.

[0029] Furthermore, the compressor front end plate assembly clamping device also includes two through-beam photoelectric sensors 121, which are respectively disposed on the side of the assembly line 101 near the support profile 115.

[0030] In this embodiment, the two photoelectric sensors 121 are located on both sides of the support profile 115 to sense the position of the tooling fixing plate 102, thereby sensing whether the rotating body assembly 301 and the front end plate assembly 201 have been moved to directly below the pressure block 108 by the assembly line 101. After sensing that they are in position, the lifting device 105 is activated to lift the tooling fixing plate 102 upwards, thereby driving the positioning fixture 103 to lift the rotating body assembly 301 and the front end plate assembly 201.

[0031] Furthermore, the compressor front end plate assembly clamping device also includes a detection photoelectric sensor 122, which is disposed on the side of the assembly line 101 near the lifting device 105.

[0032] In this embodiment, the detection photoelectric 122 is used to sense whether the height of the rotating body assembly 301 and the front end plate assembly 201 has been reached. Only after the height is reached will the pressure block 108 press down.

[0033] Furthermore, the positioning fixture 103 has a positioning pin 123, which is located on one side of the positioning fixture 103.

[0034] In this embodiment, the positioning pin 123 is provided on the positioning fixture 103 to ensure that the oil hole position of the rotating body assembly 301 is oriented after the assembly fixture is installed. That is, the positioning hole 303 of the rotating body assembly 301 is aligned with the positioning pin 123 provided on the positioning fixture 103 to ensure that the oil hole of the rotating body assembly 301 is oriented towards the operator of the production line.

[0035] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
