A compressor piston assembly machine

Abstract

The present invention relates to the field of piston assembly, and in particular to a compressor piston assembly machine. The technical problem is that currently when installing the piston ring, it is easy to cause the deformation of the piston ring to be too large, which causes the piston ring to twist and deform, and the piston ring is easy to scratch the piston surface, which may affect the sealing effect when the piston is used later, and the position of the piston ring is prone to deviation. A compressor piston assembly machine includes a mounting seat, an electric push rod, a rotating frame, etc.; the lower part of the mounting seat is fixedly connected to the electric push rod, and the upper part of the mounting seat is rotatably connected to the rotating frame. By supporting the piston ring body through a guide frame, the scratching of the piston ring body on the piston body can be reduced, thereby protecting the surface of the piston body. At the same time, the two groups of clamping plate frames can limit the piston ring body, which can keep the deformation of the piston ring body within a reasonable range, thereby protecting the piston ring body, and facilitating better insertion of the piston ring body into the annular groove on the piston body.

Description

Technical Field

[0001] The invention relates to the field of piston assembly, and in particular to a compressor piston assembly machine. Background Art

[0002] A piston compressor is a common compressor that relies on the reciprocating motion of a piston to pressurize and transport gas. A piston used in a piston compressor is usually equipped with a piston ring, and most of the piston rings have openings. When installing the piston ring, the position of the opening needs to be adjusted so that the openings on several piston rings are staggered with each other. Currently, when installing the piston ring, the piston ring needs to be stretched out and then inserted into the annular groove of the piston. During the installation of the piston ring, the piston ring is easily stretched out unreasonably, resulting in excessive deformation of the piston ring, which causes the piston ring to twist and deform. When the piston ring is inserted into the piston, the piston ring is easy to scratch the surface of the piston, which may affect the sealing effect of the subsequent piston use. In addition, there is a problem that the position of the piston ring is prone to deviation, and the position of the piston ring needs to be adjusted again, resulting in low piston assembly efficiency. Summary of the invention

[0003] In view of this, the present invention provides a compressor piston assembly machine which can keep the deformation of the piston ring within a reasonable range and reduce the scratching of the piston ring on the piston surface to protect the piston ring and the piston. At the same time, the opening position of the piston ring is not easily offset, thereby facilitating the installation of the piston ring in the correct position, thereby improving the piston assembly efficiency.

A telescopic spring 56 is connected between the clamping frame 55 on the limit ring frame 2 53 and the limit ring frame 2 53 through a hook. The two groups of clamping frames 55 are symmetrically arranged. A piston ring body 601 is placed between the upper side surfaces of the clamping frame 55 located at the bottom. The piston ring body 601 has an opening on the side close to the transmission frame 51. A threaded sleeve 57 is fixedly connected to the middle part of the long rod 41. The threaded sleeve 57 is threadedly connected to the adjusting screw 58, and the adjusting screw 58 is vertically arranged.

[0030] At first, the top frame 61 squeezes the swing clamp frame 64, so that the end of the swing clamp frame 64 away from the top frame 61 is lifted, and the torsion spring 65 is twisted. When the piston needs to be assembled, the operator puts the piston ring body 601 between the two groups of clamp frames 55 from the side of the two groups of clamp frames 55 away from the transmission frame 51, so that the piston ring body 601 contacts each clamp frame 55 in the group of clamp frames 55 located below, and the notch of the piston ring body 601 faces the direction close to the transmission frame 51, and one end of the piston ring body 601 is located between the clamping frame 62 and the swing clamp frame 64. Then the operator places the piston body 4 on the rotating frame 3, and the four rubber blocks 31 squeeze and limit the piston body 4. Then the operator starts the electric push rod 2, and the telescopic rod of the electric push rod 2 contracts to drive the transmission frame 51 and the limit ring Frame 1 52, supporting spring 521, limiting ring frame 2 53, clamping plate frame 55, telescopic spring 56, piston ring body 601, clamping frame 62, reset spring 63, swing clamping frame 64, torsion spring 65, limiting rod 71, lifting frame 72, guide frame 73, adjusting ring 74, extrusion frame 81, guide block 82, push frame 83, return spring 84, rotating roller 85, limiting clamp 86 and spiral spring 87 move downward, and the swing clamping frame 64 moves downward to separate from the top frame 61, and the torsion spring 65 rebounds to drive the swing clamping frame 64 to swing, and the swing clamping frame 64 and the clamping frame 62 clamp one end of the piston ring body 601 together, so that the opening position of the piston ring body 601 is not easily offset during installation, thereby facilitating the installation of the piston ring body 601 at the correct position, thereby improving the installation efficiency.

[0031] The telescopic rod of the electric push rod 2 then continues to shrink, the adjusting ring 74 contacts with the upper side of the piston body 4, the guide frame 73 covers the piston body 4, the guide frame 73 and the adjusting ring 74 no longer move downward, and then the telescopic rod of the electric push rod 2 continues to shrink, the guide frame 73 squeezes the clamping frame 55, the clamping frame 62 and the piston ring body 601, the guide frame 73 squeezes the two groups of clamping frames 55 to move away from each other, the telescopic spring 56 is stretched, the guide frame 73 squeezes the clamping frame 62 to move in the direction close to the transmission frame 51, the return spring 63 is stretched, the guide frame 73 squeezes the piston ring body 601, the piston ring body 601 is stretched, and then the piston ring body 601 continues to move downward and will be sleeved on the guide frame 73, and then the telescopic rod of the electric push rod 2 continues to shrink, the piston ring body 601 is separated from the guide frame 73, and then the limit ring frame 52 contacts with the adjusting screw 58, the piston ring body 601 is located outside the annular groove of the piston body 4 to be installed, and the adjusting screw 58 blocks the limit ring Frame 1 52, limit ring frame 2 53, clamp frame 55, telescopic spring 56, piston ring body 601, clamping frame 62, return spring 63, swing clamp frame 64, torsion spring 65, limit rod 71, lifting frame 72, guide frame 73, adjustment ring 74, guide block 82, push frame 83, return spring 84, rotating roller 85, limit clamp 86 and spiral spring 87 move downward, and then the telescopic rod of the electric push rod 2 continues to shrink, and the transmission frame 51 and the extrusion frame 81 continue to move downward, 521 The pushing frame 83 is stretched, and the extrusion frame 81 squeezes the pushing frame 83 to move away from the transmission frame 51. The pushing frame 83 drives the rotating roller 85, the limiting clamp 86 and the spiral spring 87 to move. The return spring 84 is compressed, and the limiting clamp 86 contacts the piston ring body 601. The limiting clamp 86 limits the piston ring body 601, so that the piston ring body 601 is flush with the annular groove on the piston body 4, which can reduce the scratching of the piston ring body 601 on the annular groove on the piston body 4, and further protect the piston ring body 601.

[0032] Then the rotating roller 85 continues to move and contacts the piston ring body 601, and the rotating roller 85 continues to move to push one end of the piston ring body 601 into the annular groove of the piston body 4 where it needs to be installed. The rotating roller 85 squeezes the piston ring body 601, thereby increasing the friction between the piston ring body 601 and the piston body 4. Then the operator rotates the rotating frame 3 for one circle, and the rotating frame 3 drives the rubber block 31 and the piston body 4 to rotate. The piston body 4 drives the piston ring body 601 to rotate through the friction force, and the rotating roller 85 squeezes the rotating piston ring body 601, so that the rotating roller 85 squeezes the piston ring body 601 for one circle, thereby squeezing the piston ring body 601 into The piston ring body 601 is inserted into the annular groove of the piston body 4 where it needs to be installed, the piston ring body 601 is propped open by the guide frame 73, and then the piston ring body 601 is sleeved on the guide frame 73, and then installed in the annular groove of the piston body 4, which can reduce the scratching of the piston ring body 601 on the piston body 4, thereby protecting the surface of the piston body 4. At the same time, the two groups of clamping plate frames 55 can limit the piston ring body 601, which can reduce the deformation of the piston ring body 601 in the vertical direction, and can keep the deformation of the piston ring body 601 within a reasonable range, thereby protecting the piston ring body 601 and facilitating better insertion of the piston ring body 601 into the annular groove on the piston body 4.

[0033] Then the operator adjusts the extension of the telescopic rod of the electric push rod 2, and the extension of the telescopic rod of the electric push rod 2 drives the transmission frame 51 and the extrusion frame 81 to move upward, and then the supporting spring 521 rebounds, the extrusion frame 81 no longer squeezes the push frame 83, and the return spring 84 rebounds, and the telescopic rod of the electric push rod 2 continues to extend to drive the transmission frame 51, the extrusion frame 81, the limit ring frame 1 52, the limit ring frame 2 53, the clamping plate frame 55, the telescopic spring 56, the piston ring body 601, the clamping frame 62, the return spring 63, the swing clamping frame 64, the torsion spring 65, the limit rod 71, the lifting frame 72, the guide frame 73, the adjusting ring 74, the guide block 82, the push frame 83, the return spring 84, the rotating roller 85, the limit clamp 86 and the spiral spring 87 to move upward, and the limit ring frame 1 52 is separated from the adjusting screw 58, and then the limiting rod 71 pushes the supporting frame 72 to move upward, and then, the telescopic rod of the electric push rod 2 continues to extend to drive the transmission frame 51, the limiting ring frame 1 52, the supporting spring 521, the limiting ring frame 2 53, the clamping plate frame 55, the telescopic spring 56, the piston ring body 601, the clamping frame 62, the reset spring 63, the swing clamping frame 64, the torsion spring 65, the limiting rod 71, the supporting frame 72, the guide frame 73, the adjusting ring 74, the extrusion frame 81, the guide block 82, the pushing frame 83, the return spring 84, the rotating roller 85, the limiting clamp 86 and the spiral spring 87 to move upward and reset, and the top frame 61 squeezes the swing clamping frame 64 again, and then the operator takes out the installed piston body 4 and the piston ring body 601.

[0034] When the piston ring body 601 needs to be installed to other annular grooves of the piston body 4, the operator needs to screw the adjusting screw 58 to move the adjusting screw 58 upward or downward, so that when the limit ring frame 52 contacts the adjusting screw 58, the piston ring body 601 is aligned with the annular groove to be installed on the piston body 4, and then screw the adjusting ring 74 to move the adjusting ring 74 upward or downward, so that when the adjusting ring 74 contacts the upper side surface of the piston body 4, the lower side surface of the guide frame 73 is flush with the upper side surface of the annular groove to be installed on the piston body 4, so as to facilitate the installation of the piston ring body 601 to other annular grooves of the piston body 4.

[0035] Embodiment 2: Based on embodiment 1, Figure 7 and Fig. 9 As shown, it also includes a limiting component. The limiting component is provided on the top frame 61. The limiting component includes a support rod 91, a bracket 93 and a partition 94. The support rod 91 is welded to one side of the top frame 61, the bracket 93 is fixedly connected to the side of the support rod 91 away from the top frame 61, and the partition 94 is fixedly connected to the middle of the bracket 93.

[0036] When the operator places the piston ring body 601 between the two groups of clamping frame 55 from the side of the two groups of clamping frame 55 away from the transmission frame 51, the partition 94 passes through the gap of the piston ring body 601, and then the outer side of the piston ring body 601 contacts the bracket 93. At this time, one end of the piston ring body 601 is located between the clamping frame 62 and the swing clamping frame 64, thereby improving the placement efficiency of the piston ring body 601, thereby improving the assembly efficiency of the piston body 4. When the limit ring frame 52 moves downward and drives the clamping frame 55 and the piston ring body 601 to move downward, the piston ring body 601 will be separated from the bracket 93 and the partition 94.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
