Description

Technical Field

[0001] The utility model relates to an online detection device for the cylinder size accuracy of an air-conditioning compressor, in particular to a feeding and alignment device and a cylinder detection device for cylinder measurement. Background Art

[0002] The cylinder is one of the key components in the air-conditioning compressor. The cylinder is used to assemble the rolling piston and the sliding vane. The rolling piston is set on the eccentric crankshaft of the compressor and rolls along the cylinder wall during cooling. The sliding vane is in close contact with the outer cylindrical wall of the rolling piston under the action of the spring force to form a dynamic seal.

[0003] The cylinder includes a cavity for placing a rolling piston and a slide slot for placing a slide. When assembling the cylinder, slide and movable piston, the precision of these three parts is very high. The precision directly affects the refrigeration quality and energy-saving efficiency of the air conditioner. Therefore, the cylinders required by the compressor are usually assembled in a selective manner, which inevitably requires the cylinders to be sorted before assembly.

[0004] When measuring cylinder sorting, the dimensional accuracy of the vane slot is involved. Online detection requires adjusting the position of the vane slot so that it can correspond exactly to the vane slot detection position of the online detection device. This involves adjusting the position and direction of the cylinder, which is often done manually. However, the manual method has high labor intensity and low production efficiency, and cannot meet the requirements of large-scale production. It is not conducive to market competition and the future development of the enterprise. Therefore, it is imperative to invent a device that can automatically adjust the angle of the cylinder.

[0028] refer to Figure 1-Figure 5This embodiment provides a feeding and alignment device for measuring a cylinder 6, which is mainly used for active position alignment of a slide groove 62 on a cylinder 6 of a cylinder 6 detection device, so as to facilitate the correct placement of the detection position on the cylinder 6 detection device.

[0029] The dimensional accuracy detection of the cylinder 6 includes the detection of the overall size of the cylinder 6 and the dimensional accuracy detection of the vane slot 62. The vane slot 62 is used to place the vane. The size of the vane slot 62 needs to be detected in order to place a vane of appropriate size to meet the assembly accuracy requirements of the air-conditioning compressor.

[0030] like Figure 4 The conventional cylinder 6 includes a middle cavity 61 for placing a piston and a slide slot 62 for placing a slide, and the slide slot 62 is connected to the middle cavity 61. When the cylinder 6 is inspected, a detection position is set for the slide slot 62. The position of the slide slot 62 may not correspond to the detection position when the cylinder 6 is loaded. Therefore, a loading alignment device is required to align the position of the cylinder 6 before the inspection, adjust the slide slot 62 of the cylinder 6 to a suitable position, and then grab and place it at the inspection position.

[0031] In this embodiment, the cylinder 6 detection device involved includes a transfer table 2, a detection table 3, a loading and alignment device and a discharge position 4. Figure 1 The feeding alignment device is arranged on the grabbing device 5, and the grabbing device 5 includes a linear module and a first claw hand 51, a second claw hand 52 and a third claw clamp 53 driven by the linear module. The first claw hand 51 moves back and forth between the transfer table 2 and the detection table 3 under the drive of the linear module, and the second claw hand 52 moves back and forth between the detection table 3 and the unloading position 4 under the drive of the linear module, and is used to grab the cylinder 6 after the cylinder 6 is detected and transported to the unloading position 4 for placement, and the third claw clamp 53 is used to grab the cylinder 6 on the unloading position 4 for transportation to the next process.

[0032] The inspection table 3 is provided with a width measuring device 31, which is used to detect the width of the slide slot 62 of the cylinder 6. The width measuring device 31 is fixedly installed on one side of the inspection table 3. The width measuring device 31 includes a width measuring part and a driving part of the width measuring part. When the cylinder 6 is placed on the inspection table, the driving part is used to extend the side width part from the bottom of the slide slot 62 into the slide slot 62 to measure the width. The feeding alignment device provided in this embodiment is used to align the position of the slide slot 62 of the cylinder 6, so that the slide slot 62 can be rotated to correspond to the position of the width measuring part, and then the slide slot 62 can be placed correspondingly above the width measuring part when it is grasped by the first claw hand 51 for parallel transportation and then lowered, so as to facilitate the extension of the width measuring part and avoid the misalignment of the position, which causes the width measuring part to get stuck.

[0033] In this embodiment, in order to simplify the structure of the alignment device, the alignment device is combined with the first gripper 51 to form a loading alignment device. The first gripper 51 is used as a material picking component 1, and is driven by a linear module as a driving module to go back and forth between the transfer table 2 and the detection table 3 to obtain the cylinder 6.

[0034] The material picking assembly 1 includes a pneumatic claw clamp 11 and a photoelectric sensor 12; the pneumatic claw clamp 11 is rotatably arranged, and the photoelectric sensor 12 is arranged on one side of the pneumatic claw clamp 11; the photoelectric sensor 12 is used to control the start or stop of the rotation of the pneumatic claw clamp 11. The cylinder 6 is obtained by setting a rotatable pneumatic claw clamp 11, and the pneumatic claw clamp 11 rotates after grabbing to drive the cylinder 6 to rotate, so as to achieve the steering adjustment of the cylinder 6. The photoelectric sensor 12 is arranged at a designated position to contact the slide slot 62 set in the cylinder 6. When the light emitted by the photoelectric sensor 12 enters the slide slot 62, the photoelectric sensor 12 feedbacks that the pneumatic claw clamp 11 stops rotating. At this time, the cylinder 6 rotates to the correct position required for detection, and the pneumatic claw clamp 11 is used to grab and place it at the detection position. The position calibration of the slide slot 62 when the cylinder 6 is automatically sorted is realized by the material finding and loading device.

[0035] The rotation driving structure of the pneumatic claw clamp 11 is set as a rotary motor 13. After acquiring the cylinder 6, the pneumatic claw clamp 11 lifts the cylinder 6 and rotates the cylinder 6 in a horizontal plane by driving the rotary motor 13 to realize the steering function of the cylinder 6.

[0036] In order to more accurately control the rotation of the pneumatic claw 11, an induction sheet 14 is provided at the output end of the rotating motor 13, and the induction sheet 14 is provided on the rotating shaft of the rotating motor 13. The induction switch combination can be used to send a start and stop signal to the automated instruction system to achieve accurate control of the rotating motor 13.

[0037] The material taking assembly 1 includes a motor mounting seat 15 for mounting a rotating motor 13, and a photoelectric sensor bracket 16 is assembled on one side of the motor mounting seat 15 for mounting a photoelectric sensor 12. The photoelectric sensor bracket 16 can be installed according to the position of the width measuring member, so as to facilitate the direction alignment and position calibration of the slide slot 62 on the cylinder 6.

[0038] According to the structure of the cylinder 6, the transfer table 2 and the inspection table 3 are both provided with a clamping column, which is used to limit the position of the cylindrical clamping column and the middle cavity 61 of the cylinder 6. In order to achieve high-precision limiting cooperation, the diameter of the clamping column is generally consistent with the diameter of the middle cavity 61 of the cylinder 6. When the cylinder 6 is grasped or placed by the pneumatic claw clamp 11, if the pneumatic claw clamp 11 grasps it tightly, the clamping column and the middle cavity 61 of the cylinder 6 will be suffocated when it is lowered, which will easily aggravate the wear of the cylinder 6.

[0039] In order to better grasp or discharge the cylinder 6 and avoid the cylinder 6 being stuck on the column, in this embodiment, the pneumatic claw clamp 11 includes a claw clamp part 112 and a propulsion part 111, and the propulsion part 111 is movably connected with the claw clamp part 112; the claw clamp part 112 pushes the cylinder 6 to be stuck on the column under the action of the propulsion part 111. By utilizing the movable connection between the propulsion part 111 and the claw clamp part 112, when the claw clamp part 112 is used to obtain the cylinder 6 to be upwardly separated from the column or the lower column, the claw clamp part 112 is used to form a circumferential shaking by utilizing the movable connection, and the cylinder 6 forms a rotational cooperation with the column under a slight swing, spiraling upward or downward, which can avoid the cylinder 6 being stuck on the column.

[0040] The movable connection between the propulsion part 111 and the claw clamp part 112 is set as follows: three movable joints 113 are set on the lower end surface of the propulsion part 111, and the claw clamp part 112 is connected through the movable joints 113. The movable joints 113 can be a ball cage universal joint. With the three movable joints 113, when the cylinder 6 is clamped with the clamping column, an eccentric shaking is formed.

[0041] The propulsion part 111 is connected to the output shaft of the rotary motor 13 and driven to rotate by the rotary motor 13. The claw clamp part 112 is movably installed below the propulsion part 111 and rotates with the rotary motor 13. Due to the active connection between the propulsion part 111 and the claw clamp part 112, in order to stably obtain the cylinder 6 and turn the cylinder 6, a limiting structure is provided between the propulsion part 111 and the claw clamp part 112. The limiting structure is used to limit or release the movement of the claw clamp part 112. Only when the cylinder 6 is lowered or raised and matched with the clamping column, the limiting structure will be driven to release the limit, so that the claw clamp part 112 and the propulsion part 111 form a movable match. Otherwise, the limiting structure is used to lock, and no movement occurs between the claw clamp part 112 and the propulsion part 111.

[0042] like Figure 3 Specifically, the limiting structure is that, on the end faces opposite to the claw clamping portion 112 and the propulsion portion 111, a socket 114 is provided on one end face, and a plug-in 115 is provided on the other end face; the plug-in 115 is driven by a telescopic cylinder 116 to be inserted into or detached from the socket 114; the plug-in 115 cooperates with the socket 114 to form the limiting structure.

[0043] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
