Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing and relates to a manipulator clamp for a compressor cylinder. Background Art

[0002] When processing large quantities of compressor cylinders, a robot is required for automatic loading. To improve the efficiency of the robot's automatic loading, it is necessary to install some special fixtures on the robot. Different workstations require different fixtures. On the dedicated machine tool for processing the suction holes of the compressor cylinder production line, when two compressor cylinders need to be disassembled and installed at once, multiple fixtures are required, which is time-consuming. It is difficult to use one fixture to disassemble two processed compressor cylinders at once and then install two unprocessed compressor cylinders. The work efficiency is relatively low.

[0003] In order to overcome the shortcomings of the existing technology, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses a compressor cylinder clamp [application number: 202021210782.9], which includes a connecting seat, a push rod, an inner spring, an inner cylinder, an outer cylinder, an end cover and at least three tightening blocks. Its special feature is that it also includes a mounting ring, a reset ring, and an upper bearing and a lower bearing arranged between the inner cylinder and the outer cylinder. However, during use, this solution still makes it difficult to disassemble two processed compressor cylinders at a time using a clamp and then install two unprocessed compressor cylinders, resulting in a relatively low work efficiency. Summary of the Invention

[0004] The purpose of the utility model is to provide a manipulator clamp for a compressor cylinder in view of the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The inner hole of the flange linear bearing is equipped with a guide column that can reciprocate along a straight line. The guide column is provided with a clamping claw floating plate at one end away from the flange linear bearing, and a nylon buffer plate is installed on the top of the clamping claw floating plate.

[0008] In the above-mentioned manipulator clamp for a compressor cylinder, the nylon buffer plate and the clamping jaw floating plate are fixed by screws, and the guide column and the clamping jaw floating plate are fixed by screws.

[0009] In the above-mentioned manipulator clamp for a compressor cylinder, a guide post baffle is provided at one end of the guide post away from the clamping claw floating plate. The guide post baffle is fixed to the guide post by screws, and the guide post baffle is in contact with the bottom end face of the flange linear bearing.

[0010] In the above-mentioned manipulator clamp of the compressor cylinder, a floating spring is provided on the guide column, and a bearing cross plate is provided on the flange linear bearing, which is screwed and fixed to the cylinder connecting plate. One end of the floating spring is against the clamp floating plate, and the other end is against the bearing cross plate.

[0011] In the above-mentioned manipulator clamp for a compressor cylinder, the jaw pad comprises a jaw pad arranged on the outside of the jaw, and the jaw pad is fixed to the jaw by screws.

[0012] In the above-mentioned manipulator clamp for a compressor cylinder, the clamping claw pad is made of nylon material.

[0028] In this embodiment, the fixture mainboard 1 is connected to the manipulator and is driven by the manipulator. When installing the unprocessed compressor cylinder, the clamping claws 3 and the clamping claw pads 4 in the two three-claw cylinders 2 with the pressing cylinder mounting structure 7 are retracted and extended into the inner hole of the compressor cylinder. When the three clamping claws 4 are expanded outward, the three clamping claws 4 can clamp the compressor cylinder. The clamping claw pads 4 can prevent damage to the inner hole of the compressor cylinder 15, and the pressing cylinder mounting structure 7 contacts the end face of the compressor cylinder to apply pressure to the compressor cylinder. When installing the compressor cylinder on the work station, it is ensured that the compressor cylinder 15 is installed in place with high installation accuracy. When it needs to be disassembled When unloading two processed compressor cylinders, the jaws 3 and jaw pads 4 in the two three-claw cylinders 2 without the press-type cylinder mounting structure 7 are retracted and extended into the inner hole of the compressor cylinder. When the three jaws 4 are expanded outward, the three jaws 4 can clamp the compressor cylinder and place the processed compressor cylinder at the next workstation. The air blowing and chip removal structure 5 is used to spray air to the two processed compressor cylinders to clean the iron filings and coolant. This device can disassemble two processed compressor cylinders at one time and then install two unprocessed compressor cylinders. The disassembly and installation of the compressor cylinders are integrated into one fixture, which can greatly improve work efficiency.

The guide post blocking piece 7b1 is fixed to the guide post 7b by screws, and the guide post blocking piece 7b1 is in contact with the bottom end surface of the flange linear bearing 7a.

[0034] In this embodiment, the guide post blocking piece 7b1 can prevent the guide post 7b from being separated from the flange linear bearing 7a, thereby improving safety and stability.

[0035] Combine Figure 2 As shown, a floating spring 7b2 is sleeved on the guide column 7b, and a bearing transverse plate 7a1 is provided on the flange linear bearing 7a, which is screwed and fixed to the cylinder connecting plate 6. One end of the floating spring 7b2 is against the clamping claw floating plate 7c, and the other end is against the bearing transverse plate 7a1.

[0036] In this embodiment, after the guide post 7b has completed sliding backward, the floating spring 7b2 can automatically reset the guide post 7b, the clamping claw floating plate 7c and the nylon buffer plate 7d through the action of elastic force.

[0038] In this embodiment, during the clamping process, the clamping claw pad 4a abuts against the inner hole wall of the compressor cylinder. The clamping claw pad 4a is made of nylon material, which can prevent damage to the inner hole of the compressor cylinder.

[0039] Combine Figure 2 、 Figure 5 As shown, the nylon buffer plate 7d is provided with a plurality of anti-interference grooves 7d1 distributed in a circular array along the center point of the nylon buffer plate 7d, and the positions of the clamping jaws 3 and the clamping jaw pads 4a correspond to the anti-interference grooves 7d1.

[0040] In this embodiment, the anti-interference groove 7d1 can prevent the nylon buffer plate 7d from colliding with the clamping jaw 3 and the clamping jaw pad 4a during movement, thereby improving safety.

[0044] In this embodiment, the air blowing nozzle seat 5a is used to install and fix the air blowing nozzle pipe 5b, and the air blowing nozzle pipe 5b is used to spray air to the two processed compressor cylinders to clean iron filings and coolant.

[0045] The working principle of this utility model is:

[0046] The fixture main board 1 is connected to the manipulator and is driven by the manipulator. When installing the unprocessed compressor cylinder, the jaws 3 and the jaw pads 4a in the two three-claw cylinders 2 with the cylinder connecting plates 6 are retracted and extended into the inner hole of the compressor cylinder. When the three jaws 4 are expanded outward, the three jaws 4 can clamp the compressor cylinder. The jaw pads 4a can prevent damage to the inner hole of the compressor cylinder 15, and the flange linear bearing 7a can facilitate the axial sliding of the guide column 7b. When installing the unprocessed compressor cylinder, the nylon buffer plate 7d contacts the end face of the compressor cylinder, giving the compressor cylinder a pressure, ensuring the installation of the compressor cylinder when installing it on the work station. In place, with high installation precision, when it is necessary to disassemble two processed compressor cylinders, the clamping jaws 3 and the clamping jaw pads 4a in the two three-claw cylinders 2 without the cylinder connecting plates 6 are retracted and inserted into the inner hole of the compressor cylinder. When the three clamping jaws 4 are expanded, the three clamping jaws 4 can clamp the compressor cylinder, and the processed compressor cylinder is placed at the next station. The air blowing nozzle pipe 5b is used to spray air to the two processed compressor cylinders to clean iron filings and coolant. The device can disassemble two processed compressor cylinders at a time and then install two unprocessed compressor cylinders. The disassembly and installation of the compressor cylinders are integrated into one fixture, which can greatly improve work efficiency.

[0047] The nylon buffer plate 7d is fixed to the clamping claw floating plate 7c by screws, and the guide post 7b is fixed to the clamping claw floating plate 7c by screws, which makes disassembly and assembly simple and convenient. The guide post baffle 7b1 can prevent the guide post 7b from being separated from the flange linear bearing 7a, which has good safety and stability. The floating spring 7b2 can automatically reset the guide post 7b, the clamping claw floating plate 7c and the nylon buffer plate 7d through the action of elastic force after the guide post 7b slides backward.

[0048] During the clamping process, the clamping claw pad 4a abuts against the inner hole wall of the compressor cylinder. The clamping claw pad 4a is made of nylon material, which can prevent damage to the inner hole of the compressor cylinder. The anti-interference groove 7d1 can prevent the nylon buffer plate 7d from colliding with the clamping claw 3 and the clamping claw pad 4a during movement, which has better safety. The three-jaw cylinder 2 drives the pneumatic claw 2a and the clamping claw 3 to close or separate. Two throttling joints 2b are connected to the side of the three-jaw cylinder 2 for connecting compressed air and exhaust.
