Description

Technical Field

[0001] This utility model belongs to the field of plunger pump assembly technology, and in particular relates to a plunger pump gasket testing mechanism. Background Technology

[0002] Currently, in the assembly and production process of plunger pumps, one of the core processes is to install springs, gaskets, and plunger covers into the plunger seat in sequence. The quality of the gasket assembly directly determines the sealing performance, pressure stability, and overall service life of the plunger pump. If there is a problem of missing gaskets, it will cause the plunger pump to malfunction during operation, and in severe cases, it may even lead to equipment shutdown or safety hazards. Therefore, the assembly of gaskets is a key link to ensure the quality of plunger pump products.

[0003] However, due to the structural design limitations of plunger pumps, after the plunger cover is assembled, the gasket inside the plunger seat is in a completely enclosed space, making it impossible for operators to directly observe whether the gasket has been correctly installed. To prevent defective products with missing gaskets from entering subsequent stages, existing technologies typically employ manual visual inspection of assembly steps or assign dedicated personnel to supervise the assembly station to reduce omissions. However, these methods, which rely on human experience, are highly subjective and easily affected by factors such as operator fatigue and attention deficit, failing to fundamentally eliminate the problem of missing gaskets and resulting in low reliability of detection.

[0004] To solve the above-mentioned technical problems, this utility model designs a plunger pump gasket detection mechanism. Utility Model Content

[0005] This invention provides a plunger pump gasket testing mechanism, which aims to solve the problems of low testing efficiency and low testing reliability of plunger pump gaskets.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plunger pump gasket detection mechanism, comprising a drive assembly, a detection assembly, and a clamping and positioning mechanism. The detection assembly is connected to the drive assembly. The detection assembly includes a main body, a clamping member, and a height detection part. The height detection part passes through the main body, and the clamping member is sleeved on the height detection part. A first elastic member is provided between the clamping member and the main body. The clamping and positioning mechanism includes a clamping assembly and multiple positioning pins. The clamping assembly is used to clamp and fix the plunger pump to be tested. The multiple positioning pins are provided in the clamping assembly. The plunger pump includes multiple mounting holes. The multiple positioning pins are correspondingly arranged with the multiple mounting holes. A spring, a gasket, and a cover are sequentially arranged in the multiple mounting holes. The clamping member and the height detection part are both arranged facing the plunger pump. The clamping member can move relative to the main body in a direction close to or away from the plunger pump.

[0007] Based on the above technical solution, the main body includes a fixed plate, a mounting plate and a clamping cover plate arranged sequentially along the direction close to the plunger pump. The drive assembly is connected to the fixed plate. The mounting plate has an inner mounting cavity. The height detection part is fixedly inserted through the fixed plate and extends into the inner mounting cavity. The clamping member is located in the inner mounting cavity and protrudes from the clamping cover plate.

[0008] Furthermore, the bottom wall of the mounting cavity is provided with a first opening, the clamping cover is provided with a second opening, a first limiting part is formed between the second opening and the first opening, and the outer wall of the clamping member is provided with a first limiting mating part. The first limiting part and the first limiting mating part cooperate with each other so that the clamping member is partially locked in the mounting cavity.

[0009] Furthermore, the inner wall of the clamping member is provided with a second limiting part, the top wall of the mounting cavity is provided with a second limiting mating part, one end of the first elastic member abuts against the second limiting part, and the other end of the first elastic member abuts against the second limiting mating part.

[0010] Based on the above technical solution, there are multiple clamping components and height detection parts, and each clamping component and height detection part is respectively set to correspond one-to-one with the mounting hole.

[0011] Based on the above technical solution, the drive assembly includes a drive cylinder and a floating joint, the fixed plate is provided with a connector, and the drive cylinder, the floating joint and the connector are connected in sequence.

[0012] Furthermore, the plunger pump gasket testing mechanism also includes a fixed bracket, the drive cylinder is fixed to the fixed bracket, the drive assembly also includes a linear bearing and a guide shaft, the linear bearing is sleeved on the guide shaft and fixed to the fixed bracket, and the bottom end of the guide shaft is fixed to the mounting plate.

[0013] Based on the above technical solution, the clamping assembly includes a base plate, a driving part, a fixed part, and a movable part. The fixed part and the movable part are disposed on the base plate. The positioning pin is disposed on the base plate between the fixed part and the movable part. The driving part is disposed on the side of the fixed part away from the movable part. The driving part can drive the movable part to move in a direction close to or away from the fixed part to clamp or release the plunger pump.

[0014] Furthermore, the fixed part is provided with a through hole, the movable part is provided with a movable shaft, the movable shaft passes through the through hole and protrudes from the fixed part, the driving part includes a piston, the end of the piston is correspondingly provided with the end of the movable shaft, and a second elastic element is provided between the base plate and the movable part along the movement direction of the movable part.

[0015] Furthermore, the fixed part has a first groove on the side wall near the movable part, and the movable part has a second groove on the side wall near the fixed part. The first groove and the second groove are correspondingly arranged to jointly enclose the clamping space.

[0016] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0017] This invention uses a drive assembly to drive the detection assembly to move towards or away from the plunger pump. When the main body moves towards the plunger pump, the clamping head gradually approaches the cover on the mounting hole and, with the assistance of the first elastic element, presses the cover downward, so that the cover is in the installed position. At this time, the height detection unit detects the height of the cover and determines whether the detected height of the cover is equal to the standard height. When the detected height is equal to the standard height, it means that a gasket has been installed inside the mounting hole. When the detected height is less than the standard height, it means that a gasket has not been installed inside the mounting hole. This allows for quick and accurate identification of whether a gasket is missing inside the plunger pump, improving detection efficiency and accuracy.

[0018] Furthermore, by ensuring that multiple locating pins in the clamping and positioning mechanism correspond one-to-one with the mounting holes of the plunger pump, the stability and precise positioning of the plunger pump during the testing process can be guaranteed, avoiding testing errors caused by positional deviations. The linkage design between the drive component and the testing component further optimizes the operation process, reduces manual intervention, and improves the overall automation level of the testing. This mechanism is compact in structure, easy to operate, and suitable for testing various specifications of plunger pump gaskets. Attached Figure Description

[0030] Combination Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a plunger pump gasket detection mechanism, including a drive assembly 51, a detection assembly 52, and a clamping and positioning mechanism 53. The detection assembly 52 is connected to the drive assembly 51. The detection assembly 52 includes a main body 521, a clamping member 522, and a height detection part 523. The height detection part 523 passes through the main body 521, and the clamping member 522 is sleeved on the height detection part 523. A first elastic member 524 is provided between the clamping member 522 and the main body 521. The clamping and positioning mechanism 53 includes a clamping assembly 531. The clamping assembly 531 is used to clamp and fix the plunger pump 54 to be tested, and a plurality of positioning pins 532 are provided in the clamping assembly 531. The plunger pump 54 includes a plurality of mounting holes 541, and the plurality of positioning pins 532 are correspondingly arranged with the plurality of mounting holes 541. A spring 542, a gasket 543 and a cover 544 are sequentially arranged in the plurality of mounting holes 541. The clamping member 522 and the height detection part 523 are both arranged toward the plunger pump 54. The clamping member 522 can move relative to the main body 521 in a direction that is closer to or farther away from the plunger pump 54.

[0031] The plunger pump gasket detection mechanism provided in this embodiment uses a drive assembly 51 to drive the detection assembly 52 to move in a direction close to or away from the plunger pump 54. When the main body 521 moves towards the plunger pump 54, the pressing head gradually approaches the cover 544 on the mounting hole 541 and presses the cover 544 downward with the assistance of the first elastic member 524, so that the cover 544 is in the installed position. At this time, the height detection unit 523 detects the height of the cover 544 and determines whether the detected height of the cover 544 is equal to the standard height. When the detected height is equal to the standard height, it means that the gasket 543 has been installed inside the mounting hole 541. When the detected height is less than the standard height, it means that the gasket 543 has not been installed inside the mounting hole 541. This allows for quick and accurate identification of whether the plunger pump 54 is missing a gasket 543, improving detection efficiency and accuracy. Furthermore, by ensuring that multiple positioning pins 532 in the clamping and positioning mechanism 53 correspond one-to-one with the mounting holes 541 of the plunger pump 54, the stability and precise positioning of the plunger pump 54 during the testing process can be ensured, avoiding testing errors caused by positional deviations. The linkage design between the drive assembly 51 and the testing assembly 52 further optimizes the operation process, reduces manual intervention, and improves the overall automation level of the testing. This mechanism is compact, easy to operate, and suitable for testing various specifications of plunger pump 54 gaskets 543.

[0032] Based on the above technical solutions, such as Figure 3 and Figure 4 As shown, the main body 521 includes a fixed plate 525, a mounting plate 526, and a clamping cover plate 527 arranged sequentially along the direction close to the plunger pump 54. The drive assembly 51 is connected to the fixed plate 525. The mounting plate 526 has a mounting cavity 5261. The height detection part 523 is fixedly inserted through the fixed plate 525 and extends into the mounting cavity 5261. The clamping member 522 is provided in the mounting cavity 5261 and protrudes from the clamping cover plate 527.

[0033] Specifically, the fixing plate 525 is used to connect the drive assembly 51, enabling the drive assembly 51 to drive the detection assembly 52. ​​The fixing plate 525 is also used to fix the height detection part 523, ensuring the stability of the height detection part 523 and achieving accurate detection by the height detection part 523. The mounting cavity 5261 of the mounting plate 526 provides a precise mounting space for the height detection part 523 and the clamping member 522, while also protecting the internal components. The clamping cover plate 527 not only prevents the clamping member 522 from detaching from the mounting cavity 5261 during movement, but also further enhances the overall structural rigidity. The part of the clamping member 522 protruding from the clamping cover plate 527 is used to directly contact the cover 544 during the detection process, clamping the cover 544 and preventing detection errors caused by the cover 544 not being installed properly. In addition, the mounting plate 526 and the clamping cover plate 527 are connected through precision-machined positioning holes, ensuring the coaxiality between the components and further improving the accuracy of the detection.

[0034] Optionally, the height detection unit 523 may be a non-contact sensor 535, whose working principle includes, but is not limited to, electromagnetic induction, photoelectric effect, ultrasonic wave or infrared light.

[0035] Furthermore, such as Figure 4 As shown, the bottom wall of the mounting cavity 5261 is provided with a first opening 5262, the clamping cover plate 527 is provided with a second opening 5271, a first limiting part 5272 is formed between the second opening 5271 and the first opening 5262, and the outer wall of the clamping member 522 is provided with a first limiting mating part 5221. The first limiting part 5272 and the first limiting mating part 5221 cooperate with each other so that the clamping member 522 is partially locked in the mounting cavity 5261.

[0036] Specifically, the size of the first opening 5262 is larger than the size of the second opening 5271, thereby forming a first limiting portion 5272. The clamping member 522 includes a first segment and a second segment. The outer wall of the first segment contacts the inner wall of the mounting cavity 5261. The second segment is disposed within the second opening 5271 and protrudes from the second opening 5271. The size of the first segment is larger than the size of the second segment, thereby forming a second limiting mating portion 5263. The cooperation between the first limiting portion 5272 and the first limiting mating portion 5221 can effectively limit the movement range of the clamping member 522 within the mounting cavity 5261, preventing the clamping member 522 from excessively extending or detaching from the mounting cavity 5261 due to the force of the first elastic member 524, thereby ensuring the stability and reliability of the clamping member 522 during the testing process.

[0037] Furthermore, such as Figure 4As shown, the inner wall of the clamping member 522 is provided with a second limiting part 5222, the top wall of the mounting cavity 5261 is provided with a second limiting mating part 5263, one end of the first elastic member 524 abuts against the second limiting part 5222, and the other end of the first elastic member 524 abuts against the second limiting mating part 5263.

[0038] Specifically, the size of the first segment of the clamping member 522 is larger than the size of the second segment, thereby forming a first limiting fit portion 5221 on the outside and a second limiting portion 5222 on the inside. The top wall of the mounting cavity 5261 is provided with a third opening. The top wall of the mounting cavity 5261, excluding the third opening, can serve as a second limiting fit portion 5263 to limit the top end of the first elastic member 524.

[0039] The first elastic element 524 provides a continuous elastic force to the clamping element 522, ensuring that the clamping element 522 maintains proper clamping of the cover 544 during the testing process. When the main body 521 moves toward the plunger pump 54, the clamping element 522 first contacts the cover 544 and gradually applies pressure under the action of the drive assembly 51, thereby compressing the first elastic element 524. The first elastic element 524 can not only adapt to covers 544 of different thicknesses, but also effectively prevent damage to the cover 544 or other components of the plunger pump 54 due to excessive pressure. In addition, the elastic restoring force of the first elastic element 524 can help the clamping element 522 quickly reset after the test, thereby reducing operation waiting time and improving testing efficiency. Furthermore, the design of the second limiting part 5222 and the second limiting mating part 5263 makes the position of the first elastic element 524 in the mounting cavity 5261 more stable, avoiding possible displacement or tilting of the first elastic element 524 during long-term use.

[0040] Based on the above technical solution, there are multiple clamping parts 522 and height detection parts 523, and each clamping part 522 and height detection part 523 is respectively provided in a one-to-one correspondence with the mounting hole 541.

[0041] Specifically, the arrangement of multiple clamping components 522 and height detection units 523 enables simultaneous detection of multiple mounting holes 541 of the plunger pump 54, significantly improving detection efficiency. Each clamping component 522 works in conjunction with its corresponding height detection unit 523 to ensure that the condition of the gasket 543 within each mounting hole 541 can be accurately identified. This one-to-one correspondence design not only reduces detection time but also improves the reliability of detection results, avoiding the accumulation of errors that may result from individual detection. Furthermore, the modular design of the multiple clamping components 522 and height detection units 523 makes the mechanism more adaptable, allowing for flexible configuration adjustments based on the number and layout of mounting holes 541 of different models of plunger pumps 54, thereby meeting the detection needs of various product specifications and improving versatility.

[0042] Based on the above technical solutions, such as Figure 2 and Figure 3 As shown, the drive assembly 51 includes a drive cylinder 511 and a floating joint 512, and the fixed plate 525 is provided with a connector 5251. The drive cylinder 511, the floating joint 512 and the connector 5251 are connected in sequence.

[0043] Specifically, the drive cylinder 511, acting as a power source, transmits driving force to the detection component 52 through the cooperation of the floating joint 512 and the connecting piece 5251, thereby enabling the detection component 52 to move precisely in the direction of approaching or moving away from the plunger pump 54. The floating joint 512 effectively compensates for assembly errors between the drive cylinder 511 and the fixed plate 525, avoiding stress concentration problems caused by insufficient machining or installation accuracy, and also reducing the impact of vibration on detection accuracy during movement. The connecting piece 5251 is fixedly connected to the fixed plate 525 by bolts or other fastening methods, ensuring stable linkage between the drive component 51 and the detection component 52. In addition, the stroke of the drive cylinder 511 can be precisely controlled by an adjustment device to adapt to the detection requirements of plunger pumps 54 with different height specifications, further enhancing the flexibility and applicability of the detection mechanism.

[0044] Furthermore, such as Figure 2 As shown, the plunger pump 54 gasket 543 detection mechanism also includes a fixed bracket 55, the drive cylinder 511 is fixed to the fixed bracket 55, the drive assembly 51 also includes a linear bearing 513 and a guide shaft 514, the linear bearing 513 is sleeved on the guide shaft 514, the linear bearing 513 is fixed to the fixed bracket 55, and the bottom end of the guide shaft 514 is fixed to the mounting plate 526.

[0045] Specifically, the fixed bracket 55 provides a stable support foundation for the entire testing mechanism, ensuring the overall stability of the mechanism during testing and avoiding testing errors caused by external forces or vibrations. The cooperative design of the linear bearing 513 and the guide shaft 514 further enhances the smoothness and accuracy of the movement of the testing component 52. The guide shaft 514, through its fixed connection to the mounting plate 526 at its bottom end, can effectively guide the testing component 52 to move linearly along a predetermined trajectory, reducing the possibility of deviation or wobbling. In addition, the use of the linear bearing 513 reduces the frictional resistance of the guide shaft 514 during movement, extending the service life of the components, while also ensuring the high efficiency of power transmission by the drive component 51.

[0046] Based on the above technical solutions, such as Figure 5 As shown, the clamping assembly 531 includes a base plate 5311, a driving part 5312, a fixing part 5313, and a movable part 5314. The fixing part 5313 and the movable part 5314 are disposed on the base plate 5311. The positioning pin 532 is disposed on the base plate 5311 between the fixing part 5313 and the movable part 5314. The driving part 5312 is disposed on the side of the fixing part 5313 away from the movable part 5314. The driving part 5312 can drive the movable part 5314 to move in a direction close to or away from the fixing part 5313 to clamp or release the plunger pump 54.

[0047] Furthermore, such as Figure 5 As shown, the fixed part 5313 is provided with a through hole 5315, the movable part 5314 is provided with a movable shaft 5316, the movable shaft 5316 passes through the through hole 5315 and protrudes from the fixed part 5313, the driving part 5312 includes a piston 5317, the end of the piston 5317 is correspondingly provided with the end of the movable shaft 5316, and a second elastic member 5318 is provided between the base plate 5311 and the movable part 5314 along the movement direction of the movable part 5314.

[0048] When the plunger pump 54 moves to the clamping assembly 531, the piston 5317 moves toward the movable shaft 5316, driving the movable shaft 5316 to move the movable part 5314 away from the fixed part 5313, increasing the distance between the fixed part 5313 and the movable part 5314, so that the plunger pump 54 is placed between the fixed part 5313 and the movable part 5314. At this time, the second elastic member 5318 is in a compressed state. Then the piston 5317 moves away from the movable shaft 5316, and the second elastic member 5318, under the action of the restoring force, pushes the movable part 5314 toward the fixed part 5313, so as to clamp the plunger pump 54 between the fixed part 5313 and the movable part 5314, thereby fixing the position of the plunger pump 54.

[0049] Furthermore, the movable part 5314 has a first recessed hole on its side wall away from the fixed part 5313, the base plate 5311 has an upwardly extending extension part 5319, the extension part 5319 has a second recessed hole, the first recessed hole and the second recessed hole are correspondingly arranged, one end of the second elastic member 5318 is disposed in the first recessed hole, and the other end of the second elastic member 5318 is disposed in the second recessed hole.

[0050] Specifically, the first and second recesses limit the second elastic member 5318, so that when the movable part 5314 moves relative to the base plate 5311, the second elastic member 5318 extends or retracts along the direction of movement of the movable part 5314. The extension 5319 is provided on the side of the base plate 5311 near the movable part 5314, and when the driving part 5312 drives the movable part 5314 to move, it can maximize the limitation of the movement of the movable part 5314 and prevent the movable part 5314 from moving excessively.

[0051] Furthermore, such as Figure 5 As shown, the fixed part 5313 has a first groove 533 on the side wall near the movable part 5314, and the movable part 5314 has a second groove 534 on the side wall near the fixed part 5313. The first groove 533 and the second groove 534 are correspondingly arranged to jointly enclose the clamping space.

[0052] The first groove 533 and the second groove 534 cooperate to further limit the position of the plunger seat, providing a stable clamping effect and preventing displacement during subsequent processing or assembly. The size of the clamping space can be adjusted according to the specific specifications of the plunger seat to accommodate different models of plungers, enhancing versatility.

[0053] Preferably, the first groove 1521 is a V-shaped groove and the second groove 1522 is a U-shaped groove. The side wall of the U-shaped groove facing the V-shaped groove is provided with an elastic pressure head. The elastic pressure head and the V-shaped groove cooperate to clamp and fix the plunger seat 16, thereby achieving three-contact point fixation of the plunger seat 16, which can effectively improve the stability and accuracy of clamping.

[0054] Optionally, there are multiple first grooves 533 and multiple second grooves 534, which enclose multiple clamping spaces and can clamp and position multiple plunger seats. There are multiple driving components 51 and multiple detection components 52, which correspond to multiple plunger pumps 54 respectively, so as to simultaneously detect multiple plunger pumps 54.

[0055] like Figure 5 As shown, the clamping and positioning mechanism 53 also includes a sensor 535, the end of which is positioned toward the clamping space to detect whether a plunger pump 54 is placed in the clamping space.

[0056] Preferably, the sensor 535 is a photoelectric sensor 535, which can operate stably in complex environments. The photoelectric sensor 535 accurately determines the presence of the plunger pump 54 in the clamping space by detecting changes in the photoelectric signal between the transmitting and receiving ends, while remaining unaffected by external light interference, ensuring the reliability of the detection results.

[0057] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
