Description

Technical Field

[0001] The present invention relates to the technical field of piston detection equipment for compressors, and particularly to a rapid detection platform for pistons of compressors. Background Art

[0002] The operation of a piston compressor is completed by the continuous change of the working volume formed by the cylinder, the air valve, and the piston that reciprocates in the cylinder. If the volume loss and energy loss in the actual operation of the piston compressor are not considered (i.e., the ideal working process), then the work completed by the crankshaft of the piston compressor for each rotation can be divided into the suction, compression, and exhaust processes. Among them, the compression process: the piston moves upward from the bottom dead center, the suction and exhaust valves are in the closed state, and the gas is compressed in the closed cylinder. Since the cylinder volume gradually decreases, the pressure and temperature gradually increase until the gas pressure in the cylinder is equal to the exhaust pressure. The compression process is generally regarded as an isentropic process; the exhaust process: the piston continues to move upward, causing the gas pressure in the cylinder to be greater than the exhaust pressure, then the exhaust valve opens, and the gas in the cylinder is discharged into the exhaust pipe under the push of the piston isobarically until the piston moves to the top dead center. At this time, due to the action of the exhaust valve spring force and the gravity of the valve plate itself, the exhaust valve closes and the exhaust ends. Thus, the compressor has completed a working cycle consisting of the three processes of suction, compression, and exhaust. After that, the piston moves downward again, repeating the above three processes, and so on in a cycle. This is the ideal working process and principle of the piston compressor.

[0003] For the existing pistons of compressors, they are directly assembled after production without special detection, resulting in a decrease in the qualified rate of the piston compressors after assembly, affecting production efficiency and increasing costs. Therefore, a rapid detection platform for pistons of compressors is needed to overcome the above problems. Summary of the Invention

[0004] In view of this, the present invention provides a rapid detection platform for pistons of compressors, which can quickly and conveniently detect the pistons of compressors.

[0005] To solve the above technical problems, the present invention provides a rapid detection platform for pistons of compressors, including a support platform. The support platform includes a bottom plate and a support block arranged on the bottom plate. Two limiting slots are opened on the support block, namely a first limiting slot and a second limiting slot;

[0006] A piston assembly that reciprocates along the length direction of the first limiting slot is arranged in the first limiting slot, and a driving assembly for driving the piston assembly to reciprocate is arranged in the second limiting slot;

[0007] A pressure detection gauge for detecting the pressure of the piston assembly is arranged on the bottom plate.

[0008] Furthermore, the support block includes two separately arranged split blocks;

[0009] The first limit slot and the second limit slot are parallel to each other.

[0010] Furthermore, the driving assembly includes a rotating rod rotatably arranged in the second limit slot, a sleeve fixedly sleeved on the rotating rod and located between the two split blocks, and an inclined collar sleeved on the outer side wall of the sleeve and cooperating with the piston assembly.

[0011] Furthermore, a limit collar is movably sleeved on the rotating rod and located between the two split blocks.

[0012] Furthermore, the piston assembly includes a connecting plate slidably arranged in the first limit slot, connecting blocks symmetrically arranged at both ends of the connecting plate, limit heads arranged on the side walls of the two connecting blocks close to each other, steel balls arranged on the side walls of the two limit heads close to each other, and a limit clamping block movably connected to the steel balls. The inclined collar is located between the two limit clamping blocks.

[0013] Furthermore, a fixing seat is arranged on the bottom plate, an installation frame is detachably arranged on the fixing seat, and the pressure detection meter is detachably connected to the installation frame;

[0014] The fixing seat includes a fixing block arranged on the bottom plate. The fixing block is provided with an insertion hole for inserting the installation frame, and a fixing component for fixing the installation frame is movably arranged on the fixing block.

[0015] Furthermore, a threaded hole perpendicular to and communicating with the insertion hole is arranged on the fixing block. The fixing component includes a screw threadedly connected to the threaded hole and a rotating handle connected to the end of the screw outside the threaded hole.

[0016] The beneficial effects of the above technical solutions of the present invention are as follows:

[0017] 1. The structure of the present invention is simple and convenient to use. By rotating the driving assembly in the second limit slot, the piston assembly reciprocates in the first limit slot, cyclically generating pressure on the pressure detection meter. By observing the fluctuation of the reading on the pressure detection meter, it can be known whether the piston assembly is qualified, and the detection operation is fast and convenient;

[0018] 2. The support block includes two separate split blocks. The driving component includes a rotating rod rotatably arranged in the second limiting slot, a sleeve fixedly sleeved on the rotating rod and located between the two split blocks, and an inclined collar obliquely sleeved on the outer side wall of the sleeve and cooperating with the piston component. The two split blocks movably clamp the sleeve to limit the sleeve, that is, to limit the driving component, ensuring that the driving component rotates in the second limiting slot without translation, avoiding adverse effects on the reciprocating sliding of the piston component in the first limiting slot.

[0019] 3. A fixed seat and a mounting frame are provided to fix the pressure detection table, which is convenient for disassembly and assembly and facilitates maintenance and replacement. Brief Description of the Drawings

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will combine the accompanying drawings of the embodiments of the present invention. Figures 1-4, clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments derived by ordinary technicians in this field fall within the scope of protection of the present invention.

[0032] like Figures 1-4 As shown, a quick detection platform for a piston of a compressor includes a support platform 1, which includes a base plate 101 and a support block arranged on the base plate 101. Two limiting grooves are provided on the support block, namely a first limiting groove 103 and a second limiting groove 104. A piston assembly 6 that moves back and forth along the length direction of the first limiting groove 103 is provided in the first limiting groove 103, and a driving assembly 5 for driving the piston assembly 6 to move back and forth is provided in the second limiting groove 104. A pressure detection gauge 4 for detecting the pressure of the piston assembly 6 is provided on the base plate 101.

[0033] Specifically, the compressor piston rapid inspection platform includes a support platform 1, which includes a base plate 101 and a support block welded to the base plate 101. The support block is provided with two limiting slots, namely a first limiting slot 103 and a second limiting slot 104. The first limiting slot 103 is provided with a piston assembly 6 that slides back and forth along the length direction of the first limiting slot 103. The second limiting slot 104 is provided with a driving assembly 5 for driving the piston assembly 6 to slide back and forth within the first limiting slot 103. A pressure test gauge 4 for detecting the pressure of the piston assembly 6 is installed on the base plate 101. The piston assembly 6 slides back and forth within the first limiting slot 103, cyclically generating pressure on the pressure test gauge 4. By observing the fluctuation of the reading on the pressure test gauge 4, it can be determined whether the piston assembly 6 is qualified. The inspection operation is fast and convenient.

[0034] According to one embodiment of the present invention, Figure 4 As shown, the support block includes two separately arranged split blocks 102, which are separately welded on the bottom plate 101. There is an accommodating space between the two split blocks 102, which is convenient for the user to manually rotate the drive assembly 5. The first limiting slot 103 and the second limiting slot 104 are parallel to each other.

[0035] Further, such as Figures 1-4As shown in the figure, the driving assembly 5 includes a rotating rod 501 rotatably arranged in the second limiting slot 104, a sleeve 502 fixedly sleeved on the rotating rod 501 and located in the accommodation space between the two split blocks 102, and an inclined collar 503 inclinedly sleeved on the outer side wall of the sleeve 502 and cooperating with the piston assembly 6. The two split blocks 102 movably clamp the sleeve 502 to limit the sleeve 502, that is, to limit the driving assembly 5, ensuring that the driving assembly 5 does not translate while rotating in the second limiting slot 104, and avoiding adverse effects on the reciprocating sliding of the piston assembly 6 in the first limiting slot 103.

[0036] In another embodiment of the present invention, as Figures 1-2 shown, two limiting collars 504 are movably sleeved on the rotating rod 501 and located between the two split blocks 102. The two limiting collars 504 are respectively located on both sides of the sleeve 502. The sleeve 502 and the two limiting collars 504 are jointly located in the accommodation space between the two split blocks 102, playing a limiting role. They are manufactured separately and used in combination.

[0037] Furthermore, the piston assembly 6 includes a connecting plate 601 slidably arranged in the first limiting slot 103, connecting blocks 602 symmetrically welded at both ends of the connecting plate 601, limiting heads 603 welded on the side walls of the two connecting blocks 602 close to each other, steel balls 604 movably installed on the side walls of the two limiting heads 603 close to each other, and a limiting clamp block 605 movably connected to the steel balls 604. The inclined collar 503 is located between the two limiting clamp blocks 605. The driving assembly 5 rotates in the second limiting slot 104, and the inclined collar 503 rotates to drive the piston assembly 6 to reciprocate and slide in the first limiting block slot, with a stable and reliable driving effect.

[0038] In one embodiment of the present invention, as Figures 1-3 shown, a fixed seat 2 is installed on the bottom plate 101 through bolts, which is convenient for disassembly and assembly. An installation frame 3 is detachably installed on the fixed seat 2, and the pressure detection gauge 4 is detachably connected to the installation frame 3. Among them, the installation frame 3 is a common existing technology and will not be further described here. The pressure detection gauge 4 is an existing technology, including a dial 401, an installation pipe sleeve 402 fixedly connected to the dial 401, and a pressure rod 403 connected to the dial 401 and movably sleeved in the installation pipe sleeve 402. The installation sleeve is detachably linked to the installation frame 3, and the pressure rod 403 is horizontally arranged and its end faces the piston assembly 6. The fixed seat 2 includes a fixed block 201 installed on the bottom plate 101. The fixed block 201 is provided with an insertion hole for inserting the installation frame 3, and a fixing component for fixing the installation frame 3 is movably installed on the fixed block 201, that is, one end of the installation frame 3 is inserted into the insertion hole, and then it is fixed with the fixing component to ensure convenient disassembly and assembly.

[0039] Furthermore, fixing block 201 is provided with a threaded hole perpendicular to and connected to the insertion hole. The fixing assembly includes a screw 202 threadedly connected to the threaded hole and a rotary handle 203 connected to the end of screw 202 located outside the threaded hole. After one end of mounting bracket 3 is inserted into the insertion hole, screw 202 is inserted into the threaded hole. Rotating handle 203 is manually rotated to thread screw 202 into the threaded hole until the end of screw 202 located in the threaded hole presses against the end of mounting bracket 3 located in the insertion hole, thereby achieving secure fixation. This provides reliable fixation and convenient assembly and disassembly.

[0040] The working principle of the present invention is as follows: After the fixing base 2, the mounting bracket 3, and the pressure gauge 4 are installed in sequence, the two limiting collars 504 are inserted into both sides of the sleeve 502 on the rotating rod 501, and then placed in the second limiting slot 104. The sleeve 502 and the two limiting collars 504 are exactly located in the accommodation space between the two split blocks 102. By manually turning, the rotating rod 501 rotates in the second limiting slot 104. At the same time, the sleeve 502 and the two limiting collars rotate in the two split blocks 102 and act as a limit, so that the inclined collar 503 does not move while rotating. The inclined collar 503 rotates, driving the piston assembly 6 to slide back and forth in the first limiting slot 103, cyclically applying pressure to the pressure rod 403 of the pressure gauge 4. When the piston assembly 6 is installed tightly and without excess play, the reading on the dial 401 fluctuates regularly, meeting the qualified standard; otherwise, it fails to meet the standard. That is, by observing the fluctuation of the reading on the dial 401, it can be known whether the piston assembly 6 is qualified, and the detection operation is fast and convenient.

Unless otherwise clearly specified and limited, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0042] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
