Description

Technical Field

[0001] This invention relates to the field of pneumatic mechanical equipment technology, and in particular to a quick-change structure for pneumatic equipment. Background Technology

[0002] In the manufacturing process of electronic products, pneumatic equipment is commonly used for material handling, such as finger cylinders and pneumatic nozzles. However, due to the non-fixed shapes, high assembly precision, and small size of electronic product components, it is common practice to add machined parts to the pneumatic equipment to conform to the product's shape or facilitate positioning. These machined parts are custom-designed to match the product and are detachably connected to the pneumatic equipment. While the pneumatic equipment can be used interchangeably for different production projects, the machined parts need to be replaced individually.

[0003] Due to rapid technological advancements and short product iteration cycles, automated production lines frequently require project changes, sometimes necessitating frequent switching between multiple projects. Each project switch necessitates the disassembly and replacement of components related to the products handled on the automated line to accommodate the different project's products. Each changeover requires unscrewing and disassembling the pneumatic equipment before replacing the components with those from other projects. This results in lengthy project changeover times and can easily lead to disorganized storage of product-related components. Summary of the Invention

[0004] The main objective of this invention is to propose a quick-change structure for pneumatic equipment, which allows for simultaneous switching of the entire pneumatic equipment and air circuit without the need to remove or disconnect air pipes. This makes disassembly and assembly convenient, and the entire set of related components remains intact, making it easy to store.

[0005] To achieve the above objectives, the present invention proposes a quick-change structure for pneumatic equipment, comprising:

[0006] Mounting base;

[0007] An air source connector is fixed to the upper surface of the mounting base. The air source connector has two first air passages. The air inlet ends of the two first air passages are respectively provided with air pipe connectors for connecting to an external air source. The air outlet ends of the two first air passages penetrate the side surface of the air source connector.

[0008] A mounting base for accommodating pneumatic equipment is provided. The mounting base has two second air passages, the inlet ends of which penetrate the side surface of the mounting base. The outlet ends of the two second air passages are respectively connected to the corresponding air chambers of the pneumatic equipment. The mounting base is detachably connected to the mounting base via a quick-change assembly, and is movably positioned. During its movement, the mounting base has a mating position abutting against the air source connection seat and a dismounted position moving away from the air source connection seat. When the mounting base is in the mating position, the outlet ends of the two first air passages are respectively connected to the inlet ends of the two second air passages.

[0009] A locking structure is used to fix the mating seat in the mating position.

[0010] In one embodiment, the lower end face of the mating seat is provided with a mating hole, the wall of the mating hole is recessed with a track groove, and the lower end face of the mating seat is provided with a first notch connecting the mating hole and the track groove;

[0011] The upper end face of the mounting base is provided with a protrusion corresponding to the mating hole. The side surface of the protrusion is provided with a limiting part. The protrusion extends into the mating hole and can rotate relative to the mating hole. The limiting part extends into the track groove from the first notch and can move along the track groove when the mounting base swings.

[0012] The quick-change assembly includes the mating hole and the protrusion.

[0013] In one embodiment, a through hole is provided on the side surface of the protrusion, and a connecting groove is provided on the upper end surface of the protrusion to connect to the through hole;

[0014] The quick-change assembly also includes a mating rod and a limiting member. The mating rod passes through the through hole, and at least one end of the mating rod protrudes from the protrusion to form the limiting portion. The limiting member is inserted from the communicating groove to fix the mating rod to the protrusion.

[0015] In one embodiment, one sidewall of the track groove is flush with one sidewall of the first notch to form a stop surface, which abuts against the limiting portion.

[0016] In one embodiment, the first notch is progressively widening in the direction from the edge of the mating hole toward the center; and / or,

[0017] Two limiting parts are provided, respectively located on opposite sides of the protrusion, and two corresponding track grooves and two corresponding notches are provided.

[0018] In one embodiment, one of the two sides of the mating seat and the air source connection seat that are in contact with each other is provided with a positioning groove. The bottom wall of the positioning groove is connected to the first air passage or the second air passage. A sealing ring is provided in the positioning groove. The end of the sealing ring protrudes from the corresponding side so as to contact the other side.

[0019] In one embodiment, the upper end face of the mounting base is provided with a locking hole;

[0020] The locking structure includes a locking rod that is movably mounted on the mating seat in the vertical direction. When the mating seat is in the mating position, the lower end of the locking rod can extend into the locking hole to fix the mating seat in the mating position.

[0021] In one embodiment, the locking structure further includes:

[0022] A support base is fixed on the mating base. The support base has a first locking groove and a second locking groove extending in the vertical direction on two adjacent sides. The upper end of the first locking groove is lower than the upper end of the second locking groove, and the lower ends of the first locking groove and the second locking groove are connected.

[0023] The through hole extends vertically and penetrates the support base and the mating base. The wall of the through hole is stepped to form an upward-facing stepped surface.

[0024] An elastic element is disposed within the through hole, and the lower end of the elastic element abuts against the stepped surface;

[0025] The side surface of the locking rod is provided with a locking pin. The locking rod is rotatably installed in the through hole along an axis that moves in the vertical direction and extends in the vertical direction. The locking pin can switch between the first locking groove and the second locking groove during the movement of the locking rod. The locking pin abuts against the upper end of the elastic member.

[0026] When the mating seat is in the mating position, the locking pin abuts against the upper wall of the first locking groove;

[0027] When the mating seat is in the disassembled position, the locking pin abuts against the upper wall of the second locking groove.

[0028] In one embodiment, when the mating seat is in the mating position, the side of the mating seat away from the air source connection seat is configured as a first side, and the first side is inclined; and / or,

[0029] A second notch is formed on the mating seat, and when the mating seat is in the mating position, the air source connection seat is located at the second notch.

[0030] In one embodiment, the upper end face of the mounting base is recessed with a mounting groove, and the air source connection seat is disposed in the mounting groove; and / or,

[0031] Both of the second air passages are equipped with air pipe connectors at their outlet ends, so as to connect with air pipe connectors on pneumatic equipment via air pipes.

[0032] In the technical solution of this invention, the mounting base and the air source connection base are fixed. The air inlet ends of the two air passages on the air source connection base are connected to an external air source through air pipe connectors. The mating base and the pneumatic equipment are combined as a whole as a quick-change assembly. The air outlet ends of the two second air passages are respectively connected to the corresponding air chambers of the pneumatic equipment through air pipes. When the mating base is fixed in the mating position by the locking structure, the mating base and the air source connection base can be laterally pressed together. At this time, the two first air passages and the two second air passages are connected, and the external air source can be connected to the pneumatic equipment. During use, air can be supplied and evacuated according to the working requirements of the pneumatic equipment. When it is necessary to change the item, the mating base is moved to the disassembly position. At this time, the mating base and the air source connection base are separated, and the quick-change assembly composed of the mating base and the pneumatic equipment can be removed as a whole. At this time, only the pre-assembled quick-change assembly adapted to other items needs to be replaced. Operators can easily perform quick-change assembly assembly by moving the mating seat between the mating and disassembly positions, eliminating the need to disassemble the machined parts on the pneumatic equipment separately. This reduces the time required and eliminates the need to disconnect the air hoses between the pneumatic equipment and the mating seat. All related components are stored together without disassembly, facilitating product parts management. For the replacement of machined parts on the pneumatic equipment within the quick-change assembly, operators can manage the process efficiently without disrupting the production line.

[0045] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0047] It should be noted that if the embodiments of the present invention involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0048] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0049] Due to rapid technological advancements and short product iteration cycles, automated production lines frequently require project changes, sometimes necessitating frequent switching between multiple projects. Each time a project is switched, the relevant components for material handling on the automated line must be disassembled and replaced to accommodate the different project products.

[0050] The machined parts and pneumatic equipment are all fastened with screws. Therefore, each time a replacement is needed, the machined parts on the pneumatic equipment must be unscrewed and disassembled before replacing the machined parts for other items. Due to the small size of the machined parts and limited space, screw removal takes a long time. Furthermore, since a single project often requires the replacement of a large number of machined parts corresponding to different locations and sizes, the replacement time is long, and there are many parts, making storage prone to disorder.

[0051] This invention proposes a quick-change structure for pneumatic equipment, which simultaneously switches the entire pneumatic equipment and air circuit. Disassembly and assembly can be completed manually with simple operation, eliminating the need for tools such as wrenches. The disassembly and assembly time is shorter than that of screw-tightening methods, and there is no need to disconnect or pull out air hoses. All related components are stored without being disassembled, facilitating the safekeeping of product parts.

[0052] Please refer to Figures 1 to 3The pneumatic equipment quick-change structure 100 includes a mounting base 1, an air source connection base 2, a mating base 3, and a locking structure 4. The air source connection base 2 is fixed to the upper surface of the mounting base 1. The air source connection base 2 has two first air passages 21, and the air inlet ends of the two first air passages 21 are respectively provided with air pipe connectors. The air outlet ends of the two first air passages 21 penetrate through the side surface of the air source connection base 2. The mating base 3 is used for mounting the pneumatic equipment 200. The mating base 3 has two second air passages 31, and the air inlet ends of the two second air passages 31 penetrate through the mating base 3. On the side surface, the outlet ends of the two second air passages 31 are respectively connected to the air chambers corresponding to the pneumatic device 200. The mating seat 3 is detachably connected to the mounting seat 1 through a quick-change assembly, and the mating seat 3 is movable. During the movement stroke of the mating seat 3, it has a mating position that abuts against the air source connection seat 2 and a disassembly position that is far away from the air source connection seat 2. When the mating seat 3 is in the mating position, the outlet ends of the two first air passages 21 are respectively connected to the inlet ends of the two second air passages 31. The locking structure 4 is used to fix the mating seat 3 in the mating position.

[0053] In the technical solution of this invention, the mounting base 1 and the air source connection base 2 are fixed. The air inlet ends of the two air passages on the air source connection base 2 are connected to an external air source through air pipe connectors. The mating base 3 and the pneumatic device 200 are combined as a whole as a quick-change component. The air outlet ends of the two second air passages 31 are respectively connected to the corresponding air chambers of the pneumatic device 200 through air pipes. When the mating base 3 is fixed in the mating position by the locking structure 4, the mating base 3 and the air source connection base 2 can be laterally pressed together. At this time, the two first air passages 21 and the two second air passages 31 are connected, and the external air source can be connected to the pneumatic device 200. During use, air can be supplied and evacuated according to the working requirements of the pneumatic device 200. When it is necessary to change the item, the mating base 3 is moved to the disassembly position. At this time, the mating base 3 and the air source connection base 2 are separated, and the quick-change component consisting of the mating base 3 and the pneumatic device 200 can be removed as a whole. At this time, only the pre-assembled quick-change component adapted to other items needs to be replaced. The operator can easily perform quick-change assembly by moving the mating seat 3 between the mating and disassembly positions, without needing to separately disassemble the machined parts on the pneumatic device 200. This reduces the time required and eliminates the need to disconnect the air hoses between the pneumatic device 200 and the mating seat 3. All related components are stored together without disassembly, facilitating product parts management. For replacing the machined parts on the pneumatic device 200 within the quick-change assembly, the operator can manage the process efficiently without disrupting the production line's replacement time.

[0054] It should be noted that the thickness directions of mounting base 1, air source connection base 2, and mating base 3 correspond to the vertical direction. The upward-facing end face of each component is the upper end face, and the downward-facing end face is the lower end face. The side surfaces extend circumferentially and connect the upper and lower end faces. The side surface of air source connection base 2 does not refer to a specific side. In the mating position, when mating base 3 and air source connection base 2 are in contact in the left-right direction, the side surface of air source connection base 2 corresponds to the left side or rear side.

[0055] For details, please refer to Figure 2 Each of the two first air passages 21 has an air pipe connector A at its inlet. The two air pipe connectors A are connected to an external air source via two air pipes. The two first air passages 21 are independent of each other. Each of the two second air passages 31 has an air pipe connector B at its outlet. The two second air passages 31 are also independent of each other. The pneumatic device 200 has two air pipe connectors C. Air pipe connectors B and their corresponding air pipe connectors C are connected via air pipes. When the mating seat 3 is in the mating position, the two air pipe connectors A, the two first air passages 21, the two second air passages 31, the two air pipe connectors B, and the two air pipe connectors C are correspondingly connected, ensuring a continuous air path for the pneumatic device 200, facilitating its intake and exhaust switching during operation. By constructing the air path on the mating seat 3 and the air source connection seat 2, the mating seat 3 and the pneumatic equipment 200 can form a quick-change assembly. Without needing to plug or unplug the air pipe at the air pipe connector C of the pneumatic equipment 200, the connection with the first air passage 21 and the second air passage 31 enables a quick switch of the air path when the pneumatic equipment 200 is replaced. Due to the matching relationship between the mating seat 3 and the air source connection seat 2, even if the models and structures of the starting equipment corresponding to different projects are different, it is only necessary to reconnect the air pipe connectors B and C in the quick-change assembly. This does not affect the operator's replacement of the mating seat 3 when changing projects.

[0056] It should be understood that, given that pneumatic equipment 200 is universally recyclable, the replacement of processed parts can be carried out in advance according to the production plan. When pneumatic equipment 200 is not universally recyclable, mating seat 3 and new starting equipment can also be pre-installed according to the production plan.

[0057] Mounting base 1 is fastened to the machine base with screws, and pneumatic equipment 200 is fastened to mating base 3 with screws. Corresponding holes, grooves, and rib structures can be provided on the upper end face of mating base 3 to position and engage with pneumatic equipment 200.

[0058] The movable connection method between the mating seat 3 and the mounting seat 1 is not limited. The conversion between the mating position and the disassembly position of the mating seat 3 can be achieved by rotation, translation, or lifting. This invention does not limit this.

[0059] Please refer to Figures 4 to 6 The lower end face of the mating seat 3 is provided with a mating hole 32, and the wall of the mating hole 32 is recessed with a track groove 33. The lower end face of the mating seat 3 is provided with a first notch 34 connecting the mating hole 32 and the track groove 33. The upper end face of the mounting seat 1 is provided with a protrusion 11 corresponding to the mating hole 32. The side surface of the protrusion 11 is provided with a limiting part 12. The protrusion 11 extends into the mating hole 32 and can rotate relative to the mating hole 32. The limiting part 12 extends from the first notch 34 into the track groove 33 and can move along the track groove 33 when the mating seat 3 swings. The quick-change assembly includes the mating hole 32 and the protrusion 11. In this structure, the mating position and the disassembly position are two positions with a certain distance between them during the rotation of the mating seat 3. In this structure, the operation is simple and the disassembly and assembly operations can be completed without the use of tools such as wrenches. The disassembly and assembly time is shorter than that of screw fastening.

[0060] When the operator installs the quick-change component, the mating seat 3 faces downward, so that the protrusion 11 extends into the mating hole 32, and the limiting part 12 extends from the first notch 34 into the track groove 33. When the mating seat 3 and the mounting seat 1 are in contact, the installation is in place. The operator rotates the mating seat 3, so that the protrusion 11 and the mating hole 32 rotate relative to each other. The limiting part 12 can move along the track groove 33. After rotating a certain angle, the limiting part 12 is located in the track groove 33 and is offset from the first notch 34 in the circumferential direction. Therefore, the position of the mating seat 3 in the vertical direction is limited. When the mating seat 3 rotates to abut against the side of the air source connection seat 2, the mating seat 3 reaches the mating position. The locking structure 4 keeps the mating seat 3 and the mounting seat 1 fixed, thereby completing the installation action. When it is necessary to replace the quick-change component, first unlock the locking structure 4, rotate the mating seat 3 in the opposite direction, and the mating seat 3 and the air source connector will gradually move away from each other. During the rotation of the mating seat 3, the relative position of the limiting part 12 and the first notch 34 changes. When the limiting part 12 corresponds to the first notch 34, the disassembly position is reached. At this time, the operator moves the mating seat 3 upward, and the limiting part 12 can be disengaged from the first notch 34, so that the mating seat 3 can be disassembled.

[0061] It should be noted that the guide between the mating seat 3 and the mounting seat 1 relies on the protrusion 11 and the mating hole 32, and the installation and positioning rely on the contact of their end faces. The mating position is determined based on the position of the air source connection seat 2. Therefore, the circumferential dimension of the track groove 33 is not limited, as long as it can adapt to the rotation requirements of the mating seat 3 when switching between different positions.

[0062] During the relative rotation of the mating seat 3 and the mounting seat 1, the movement trajectory of the limiting part 12 within the track groove 33 is an arc. Therefore, the track groove 33 can be configured as a fan shape. For ease of processing, the track groove 33 is configured as an elongated hole, and the limit rotation stroke of the limiting part 12 within the track groove 33 is limited by the length of the elongated hole.

[0063] Because the project involves many starting devices, in actual setup, there may be multiple pneumatic quick-change structures 100 spaced apart. In this case, since the quick-change components achieve quick installation and replacement through rotation, if the rotation stroke is too large, it may interfere with adjacent quick-change structures or other structures on the production line. Therefore, the position of the side wall of the track groove 33 needs to be set reasonably to ensure that when the limiting part 12 abuts against the side wall corresponding to the track groove 33, the end of the mating seat 3 will not collide with other components.

[0064] Please refer to Figure 7 One sidewall of the track groove 33 is flush with one sidewall of the first notch 34 to form a stop surface 50, which abuts against the limiting part 12. During the rotation of the mating seat 3, since both the limiting part 12 and the first notch 34 are hidden, the relative positions of the limiting part 12 and the first notch 34 cannot be identified. With this design, when the limiting part 12 rotates to abut against the stop surface 50, the mating seat 3 cannot continue to rotate. Simultaneously, the limiting part 12 reaches the position opposite to the first notch 34, i.e., the disassembly position. This improves operational convenience; during the limiting rotation, the stop surface 50 facilitates the user's judgment that the limiting part 12 has reached the disassembly position. The mating position can be determined when the mating seat 3 and the air source connection seat 2 abut against each other. Therefore, the other side of the track groove 33 opposite to the stop surface 50 does not need to be limited.

[0065] Furthermore, along the direction from the edge of the mating hole 32 towards the center, the first notch 34 is gradually widened, that is, the first notch 34 is trumpet-shaped, which facilitates the insertion and mating of the limiting part 12.

[0066] To improve the stability of the rotational fit, two limiting parts 12 are provided, respectively located on opposite sides of the protrusion 11, and two corresponding track grooves 33 and first notches 34 are provided. That is, the two track grooves 33 are arranged in a centrally symmetrical manner.

[0067] The shape of the protrusion 11 is not limited. When the protrusion 11 is cylindrical, it can achieve a good fit with the mating hole 32. However, when the protrusion 11 is polygonal, it can also rotate and fit with the mating hole 32.

[0068] The protrusion 11 and the limiting part 12 can be integrally formed. In this embodiment, please refer to... Figure 5The protrusion 11 has a through hole on its side surface and a connecting groove 111 on its upper end surface that connects to the through hole. The quick-change assembly also includes a mating rod and a limiting member (not shown in the figure). The mating rod passes through the through hole, and at least one end of the mating rod protrudes from the protrusion 11 to form a limiting part 12. The limiting member is inserted into the connecting groove 111 to fix the mating rod to the protrusion 11. Quick-change is achieved through a pin-type mechanical structure combined with rotation, which is simple in structure and easy to operate. The mating rod can be detachably installed into the through hole, facilitating replacement in case of improper operation or bending after prolonged use. Considering the mating rod and through hole are a shaft-hole mating structure with clearance fit and relative movement, the mating rod may move within the through hole during the rotation of the mating seat 3. Therefore, a limiting member is used to firmly fix the mating rod against the protrusion 11, ensuring the relative position of the mating rod and protrusion 11. When disassembly of the mating rod is required, the limiting member can be removed. The limiting member can be a threaded connection or a plug. This invention does not limit this. When only one limiting part 12 is provided, one end of the mating rod protrudes from the protrusion 11, and the other end is inside the through hole. When two limiting parts 12 are provided, both ends of the mating rod protrude from the protrusion 11.

[0069] The protrusion 11 extends into the mating hole 32. The protrusion 11 can be flush with the upper end surface of the mating seat 3 or lower than the upper end surface of the mating seat 3.

[0070] Furthermore, the upper end face of the mounting base 1 is recessed with a mounting groove 10, and the air source connection seat 2 is disposed in the mounting groove 10. When the air source connection seat 2 is installed, it can be guided by the mounting groove 10, and two opposite side walls of the mounting groove 10 can play a limiting role.

[0071] Since the mating seat 3 and the air source connecting seat 2 connect the first air passage 21 and the second air passage 31 through their end faces abutting each other, considering the influence of machining errors and machining accuracy, in order to ensure the sealing performance after the first air passage 21 and the second air passage 31 are connected, please refer to... Figure 3 and Figure 5On one of the two sides of the mating seat 3 and the air source connecting seat 2 that are in contact with each other, a positioning groove is provided on one side. The bottom wall of the positioning groove is connected to the first air passage 21 or the second air passage 31. A sealing ring 5 is provided in the positioning groove, and the end of the sealing ring 5 protrudes from the corresponding side to contact the other side. A groove can be provided on the air source connecting seat 2 or the mating seat 3. The sealing ring 5 is embedded in the groove and has a stable installation position. The end of the sealing ring 5 protrudes from the corresponding side. When the mating seat 3 abuts against the air source connecting seat 2, the sealing ring 5 is squeezed. On the one hand, it can fill the gap between the mating seat 3 and the air source connecting seat 2, thereby ensuring the sealing fit of the first air passage 21 and the second air passage 31. On the other hand, it can provide a certain elastic pre-tightening force to cooperate with the locking structure 4. It should be understood that the through hole of the sealing ring 5 is connected to the first air passage 21 and the second air passage 31 so that gas can pass through smoothly.

[0072] Correspondingly, two sealing rings 5 ​​and two grooves are provided one-to-one, corresponding to the two first air passages 21.

[0073] This invention does not limit the specific form of the locking structure 4. In some embodiments, pin holes can be provided on both the mating seat 3 and the mounting seat 1. When the mating seat 3 is in the mating position, the two pin holes are connected to each other, allowing the pin to be inserted. In other embodiments, the locking structure 4 can also be a latch and a groove that cooperate with each other.

[0074] In this embodiment, the upper end face of the mounting base 1 is provided with a locking hole 41; the locking structure 4 includes a locking rod 42 that is movably mounted on the mating base 3 in the vertical direction. When the mating base 3 is in the mating position, the lower end of the locking rod 42 can extend into the locking hole 41 to fix the mating base 3 in the mating position. With this configuration, the locking rod 42 can be modularly mounted with the mating base 3 without considering the storage problem of the locking rod 42. An active drive mechanism can be provided, such as a cylinder, motor, or gear rack mechanism, to drive the locking rod 42 to move actively, or it can be operated manually.

[0075] Please refer to Figures 8 to 9The locking structure 4 also includes a support base 43 and an elastic element. The support base 43 is fixed on the mating base 3. Two adjacent sides of the support base 43 are provided with a first locking groove 431 and a second locking groove 432 extending in the vertical direction. The upper end of the first locking groove 431 is lower than the upper end of the second locking groove 432. The lower ends of the first locking groove 431 and the second locking groove 432 are connected. The through hole extends in the vertical direction and penetrates the support base 43 and the mating base 3. The hole wall of the through hole is stepped to form an upward-facing stepped surface. The elastic element is disposed in the through hole, and the lower end of the elastic element... The locking rod 42 has a locking pin 421 on its side surface. The locking rod 42 moves vertically and is rotatably mounted in the through hole along an axis extending vertically. During the movement of the locking rod 42, the locking pin 421 can switch between the first locking groove 431 and the second locking groove 432. The locking pin 421 abuts against the upper end of the elastic element. When the mating seat 3 is in the mating position, the locking pin 421 abuts against the upper wall of the first locking groove 431. When the mating seat 3 is in the disassembled position, the locking pin 421 abuts against the upper wall of the second locking groove 432. The elastic element provides preload, providing an upward elastic force to the locking pin 421, thereby limiting the position of the locking rod 42 and ensuring a tight fit between the locking pin 421 and the support seat 43. This structure allows for manual operation by the operator to raise and lower the locking rod 42 and rotate it, thus enabling locking and unlocking switching without the locking rod 42 falling off.

[0076] When locked, the locking pin 421 abuts against the upper wall of the first locking groove 431 under the action of the elastic element, and the lower end of the locking rod 42 is inserted into the locking hole 41. When unlocking is required, the operator first presses down the locking rod 42, so that the locking pin 421 overcomes the elastic force and moves to the lower end of the first locking groove 431. Then, the operator rotates the locking rod 42, so that the locking pin 421 can move in the connecting channel at the lower end of the first locking groove 431 and the second locking groove 432. When the locking pin 421 moves to the lower end of the second locking groove 432, the operator releases the locking rod 42. At this time, under the action of the rebound force, the locking pin 421 automatically moves up and abuts against the upper wall of the second locking groove 432. Because the second locking groove 432 is higher than the first locking groove 431, the locking rod 42 is driven to move up synchronously and separate from the locking hole 41, thus completing the unlocking action.

[0077] In this embodiment, the elastic element is set as a spring, which is sleeved on the outer surface of the locking rod 42 and located on the lower side of the locking pin 421.

[0078] It should be noted that the support base 43 can be integrally formed with the mating base 3. In this case, the through hole is set as a stepped hole, and the stepped surface can be formed on the support base 43, on the mating base 3, or at the connection between the support base 43 and the mating base 3. In this embodiment, the support base 43 is fastened to the mating base 3 by screws. Therefore, the through hole spans the support base 43 and the mating base 3. The diameter of the hole segment on the support base 43 is larger than the diameter of the hole segment on the mating base 3, thus exposing the mating base 3 and forming a stepped surface with the end face of the through hole.

[0079] When the support base 43 and the mating base 3 are combined, in order to facilitate the installation and positioning of the support base 43 and the mating base 3, square protrusions and square holes are provided on the sides of the support base 43 and the mating base 3 facing each other, so as to limit the horizontal position of the support base 43 while positioning.

[0080] Furthermore, when the mating seat 3 is in the mating position, the side of the mating seat 3 away from the air source connection seat 2 is set as the first side 30, and the first side 30 is inclined. This can prevent the mating seat 3 from interfering with and colliding with the adjacent structure due to the sharp corners of its edges during the rotation unlocking process.

[0081] A second notch 35 is formed on the mating seat 3. When the mating seat 3 is in the mating position, the air source connection seat 2 is located at the second notch 35. This arrangement makes the overall structural layout more compact, and the second notch 35 can be rounded to ensure that it avoids collision with the air pipe connector during rotation.

[0082] The starting device will be explained using a pneumatic finger.

[0083] exist Figure 1 In this embodiment, the air source connector 2 is threadedly connected to the mounting base 1. The sealing ring 5 is connected to the air source connector 2 by means of bonding or other methods. The pneumatic finger and the mating seat 3 are threadedly connected. The mating seat 3 is provided with a mating hole 32 and a track groove 33, and the mounting base 1 is provided with a protrusion 11 and a limiting part 12. In the locked state, the passage formed by the first air passage 21 and the second air passage 31 allows gas to pass through, and the sealing ring 5 can prevent gas leakage. In the disassembled state, the connection between the first air passage 21 and the second air passage 31 is disconnected, but it does not affect the air pipe connecting the first air passage 21 to the air source, nor does it affect the air pipe connecting the second air passage 31 to the pneumatic finger. The mating seat 3 and the pneumatic finger can be quickly replaced as a whole, realizing the replacement of the entire set of product-related parts and shortening the replacement time. The quick-change structure of the mating seat 3 and the mounting base 1 has high precision and good positioning effect, and no need to readjust the position after the whole replacement.

[0084] Building upon the achievement of quick replacement of product-related components, simultaneous rapid switching of pneumatic circuits is also realized, eliminating the need for disconnecting or reconnecting air hoses, thus greatly improving the convenience of switching product-related components. There is no need to disassemble the processed parts on the pneumatic fingers when changing processed products on the production line. This solves the problems of long replacement times for product-related components containing pneumatic equipment and the difficulty in storing the replaced parts.

[0085] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
