Description

Technical Field

[0001] The utility model relates to a compressor valve plate pin pressing device. Background Art

[0002] In modern industrial production, particularly in the manufacturing sector, the assembly of compressor valve plates often involves precisely pressing multiple small parts, such as pins, into their corresponding components. Traditional pin-pressing operations typically rely on manual labor or semi-automated equipment, which not only consumes a significant amount of manpower but also lacks the accuracy and efficiency to meet the demands of modern, high-efficiency, and high-precision production.

[0003] The manual press-in process has several limitations, such as operator fatigue, inconsistent operation leading to variations in press-in position and depth, and low operating speeds. These factors often lead to unstable product quality, increased scrap rates, and higher production costs. In light of this, the present invention proposes a compressor valve plate pin press-in device to address these issues. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example:

[0032] like Figure 1-10 As shown, this embodiment proposes a compressor valve plate pin pressing device, including a pressing platform 10, an automatic pressing machine 11 is provided on the pressing platform 10, and a moving block 12 that moves up and down is provided on the automatic pressing machine 11;

[0033] A rotating tower 20 is rotatably provided on the moving block 12, and a mounting block 21 is provided on the rotating tower 20. The mounting block 21 has a movable hole 23, and a push rod 40 is slidably provided in the movable hole 23. A connecting pipe 22 is also fixedly provided on the mounting block 21, and the connecting pipe 22 is sleeved on the outer wall of the push rod 40. A clamping assembly 30 is provided on the connecting pipe 22, and the clamping assembly 30 is coaxially arranged with the push rod 40. The clamping assembly 30 clamps the pin in the inner cavity of the connecting pipe 22, and the push rod 40 descends to push the pin out of the clamping assembly 30 and press it onto the compressor valve plate.

[0034] In this case, the moving block 12 is slidably arranged on the automatic pressing machine 11. When the pin needs to be pressed in, the moving block 12 descends to drive the pin to move toward the compressor valve plate.

[0035] The ejector rod 40 is ejected from the movable hole 23 by a hydraulic push rod.

[0036] In this embodiment, when pressing the pin, a robotic arm is placed on the pressing platform 10, and the pin is sent into the clamping assembly 30 by the robotic arm. Then, the compressor valve plate is placed on the pressing platform 10, and at the same time, the automatic pressing machine 11 drives the moving block 12 to descend, so that the rotating tower 20 descends, thereby causing the mounting block 21 to move toward the compressor valve plate. When the clamping assembly 30 is aligned with the hole on the compressor valve plate, the push rod 40 is pushed out from the movable hole 23 by the hydraulic push rod, and the pin on the clamping assembly 30 is pressed into the compressor valve plate by the push rod 40. After the pressing is completed, the moving block 12 is lifted, driving the rotating tower 20 to lift, and then the next set of compressor valve plates can be replaced;

[0037] By setting up a pressing platform 10, an automatic pressing machine 11, a moving block 12, a rotating tower 20, a mounting block 21, a connecting pipe 22, a clamping assembly 30 and a push rod 40, the pins are automatically and accurately pressed into place. The device integrates the automatic pressing machine 11 and the moving block 12, and the pins are automatically sent into the clamping assembly 30 by a robotic arm. The automatic pressing machine 11 drives the moving block 12 and the rotating tower 20 to complete the pin pressing operation, thereby reducing manual intervention and improving production efficiency.

[0038] Specifically, the mounting blocks 21 are provided in multiple groups, and the multiple groups of mounting blocks 21 are arranged on the rotating tower 20 in a circular array;

[0039] The diameters of the plurality of movable holes 23 are arranged in order from small to large, and the diameter of each group of push rods 40 is adapted to the diameter of each group of movable holes 23 .

[0040] In this case, a servo motor (not shown in the figure) is provided on the moving block 12 for driving the rotating tower 20 to rotate so that the push rods 40 of different diameters are arranged toward the compressor valve plate.

[0041] In this embodiment, when pins of different diameters need to be pressed in, the servo click drives the rotating tower 20 to rotate so that the movable hole 23 adapted to the pin diameter is set toward the compressor valve plate, and then the above steps are repeated to press in the pins;

[0042] Of course, in the process of pressing the pins into one set of movable holes 23, other pins of different diameters can be placed in the remaining corresponding movable holes 23 and the connecting pipes 22 by the robotic arm. After the previous set of pins are pressed in, the rotary tower 20 is rotated so that the pins installed later are set toward the compressor valve plate and pressed into the compressor valve plate.

[0043] Through the above steps, the pressing process of pins of different diameters can be completed without stopping the machine, which provides overall practicality. At the same time, during the process of pressing the pins, other pins can be installed in other movable holes 23 and connecting tubes 22, facilitating a more efficient pressing process.

[0044] Specifically, the clamping assembly 30 includes a clamping tube 33 , and the clamping tube 33 is provided with multiple groups of elastic clamping claws 34 ;

[0045] An annular deformation groove 32 is formed on the clamping tube 33 , and a plurality of groups of elastic clamping claws 34 are disposed at the annular deformation groove 32 .

[0046] In this embodiment, when clamping the pin, the robot arm sends the pin between the multiple groups of elastic clamping claws 34, and the pin is clamped by the multiple groups of elastic clamping claws 34.

[0047] Specifically, a protrusion 35 is provided on the elastic clamping claw 34 , and contact inclined surfaces 36 are provided at both ends of the protrusion 35 .

[0048] In this embodiment, when clamping the pin, the robot arm inserts the pin into the movable hole 23 and the connecting tube 22. When the pin contacts the protrusion 35, the protrusion 35 expands and deforms outward to wrap the pin. When the robot arm separates from the pin, the elastic clamping claw 34 clamps the pin.

[0049] Of course, the annular deformation groove 32 can facilitate the elastic clamping claw 34 to drive the protrusion 35 to open and deform outward;

[0050] Of course, the contact slope 36 can facilitate the pin to quickly enter the movable hole 23 and the connecting pipe 22.

[0051] Specifically, a fixing tube 31 is further provided on the clamping tube 33, and the fixing tube 31 is fixedly connected to the clamping tube 33;

[0052] The fixing pipe 31 is threadably connected to the outer wall of the connecting pipe 22 .

[0053] In this embodiment, by means of the threaded cooperation between the fixing tube 31 and the connecting tube 22 , when the elastic clamping claw 34 is damaged, the elastic clamping claw 34 can be quickly replaced.

[0054] Specifically, the multiple groups of elastic clamping claws 34 are arranged in a ring array, and the multiple groups of protrusions 35 are combined to form a clamping groove 37 , and the diameter of the clamping groove 37 is smaller than the diameter of the push rod 40 .

[0055] In this case, the pins and the multiple sets of protrusions 35 are interference fit;

[0056] The elastic clamping claws 34 are made of elastic material.

[0057] Specifically, the protrusion 35 is made of hard rubber material.

[0058] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
