Description

Technical Field

[0001] This invention relates to the field of parts processing technology, and in particular to a positioning and unloading device. Background Technology

[0002] In the manufacturing process of some household appliances, metal pipes are needed as liquid circulation channels, such as copper pipes in air conditioners and water heaters. Metal pipes are typically connected by bending metal elbows to create these liquid circulation channels. These metal elbows are usually made by first bending the metal pipe and then cutting it to a specific position.

[0003] However, currently, the common practice is for operators to clamp and position the metal elbow using a fixture before cutting. After cutting, the fixture is released and the metal elbow is removed before clamping the next metal elbow, resulting in low processing efficiency for metal elbows. Summary of the Invention

[0018] A first ejection spring is sleeved on the first ejection block and abuts against the first clamping plate; wherein...

[0019] When the first clamping plate and the second clamping plate clamp the metal elbow, the first ejector spring is in normal condition. When the first clamping plate and the second clamping plate move away from each other, the first ejector block moves closer to the first positioning groove under the action of external pressure, so as to push the metal elbow out of the first positioning groove.

[0020] In an optional embodiment, the positioning and unloading device further includes:

When the first clamping plate and the second clamping plate move away from each other, the second ejector block moves closer to the second positioning groove under the action of external pressure, so as to push the metal elbow out of the second positioning groove.

[0024] In one optional embodiment of the invention, when a set of first clamping plates and second clamping plates are provided, the positioning and ejection device includes a first abutting member and a second abutting member; wherein,

[0025] The first abutment and the second abutment are respectively installed on the support assembly.

[0036] The second support base is located on the second side of the second support plate, wherein the second linear motion output device is fixed on the second support base, and the output shaft of the second linear motion output device passes through the second support plate.

[0049] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0050] In the manufacturing process of some household appliances, metal pipes are needed as liquid circulation channels, such as copper pipes in air conditioners and water heaters. Metal pipes are typically connected by bending metal elbows to create these liquid circulation channels. These metal elbows are usually made by first bending the metal pipe and then cutting it to a specific position.

[0051] However, currently, the common practice is for operators to clamp and position the metal elbow using a fixture before cutting. After cutting, the fixture is released and the metal elbow is removed before clamping the next metal elbow, resulting in low processing efficiency for metal elbows.

[0052] Based on the aforementioned technical problems, this invention provides an embodiment that may include a support assembly 1, at least two stops 2, a guide shaft 3, at least one set of first clamping plates 4 and second clamping plates 5, a first linear motion output device 6, a second linear motion output device 7, a first pull shaft 8, and a second pull shaft 9. At least two stops 2 are fixed to the support assembly 1, and an accommodating space is formed between adjacent stops 2. The guide shaft 3 is horizontally mounted on the support assembly 1 and passes through the stops 2. The first clamping plates 4 and the second clamping plates 5 are located in the accommodating space and are respectively sleeved on the guide shaft 3, wherein the first clamping plates 4 and the second clamping plates 5 are arranged opposite each other to clamp the metal elbow 19. The first linear motion output device 6 is fixed to a first side of the support assembly 1, and the second linear motion output device 7 is fixed to a second side of the support assembly 1. The first pull shaft 8 passes sequentially through the stop block 2, the first clamping plate 4, and the second clamping plate 5, and is fixed to the first clamping plate 4. The first pull shaft 8 is also fixed to the output shaft of the first linear motion output device 6. The second pull shaft 9 passes sequentially through the stop block 2, the first clamping plate 4, and the second clamping plate 5, and is fixed to the second clamping plate 5. The second pull shaft 9 is also fixed to the output shaft of the second linear motion output device 7. When the first linear motion output device 6 and the second linear motion output device 7 operate, they drive the first clamping plate 4 and the second clamping plate 5 away from each other to unload the metal elbow 19. The first linear motion output device 6 and the second linear motion output device 7 respectively drive at least one set of opposing first clamping plates 4 and second clamping plates 5 to move linearly closer or further apart along the guide shaft 3, thereby clamping the metal elbow 19 when moving closer together and releasing it when moving further apart. Therefore, the positioning and unloading device can simultaneously achieve the positioning and unloading of multiple metal elbows 19, which can greatly improve the processing efficiency of the metal elbows 19.

[0053] Reference Figure 1-7 This invention provides a positioning and unloading device, which may include a support assembly 1, at least two stops 2, a guide shaft 3, at least one set of first clamping plates 4 and second clamping plates 5, a first linear motion output device 6, a second linear motion output device 7, a first pull shaft 8, and a second pull shaft 9, wherein:

[0054] At least two of the stops 2 are fixed to the support assembly 1, and an accommodating space is formed between adjacent stops 2. The guide shaft 3 is horizontally mounted on the support assembly 1 and passes through the stops 2. The first clamping plate 4 and the second clamping plate 5 are located in the accommodating space and are respectively sleeved on the guide shaft 3, wherein the first clamping plate 4 and the second clamping plate 5 are arranged opposite to each other to clamp the metal elbow 19. The first linear motion output device 6 is fixed to the first side of the support assembly 1, and the second linear motion output device 7 is fixed to the second side of the support assembly 1.

[0055] The first pull shaft 8 passes sequentially through the stop block 2, the first clamping plate 4, and the second clamping plate 5, and is fixed to the first clamping plate 4. The first pull shaft 8 is also fixed to the output shaft of the first linear motion output device 6. The second pull shaft 9 passes sequentially through the stop block 2, the first clamping plate 4, and the second clamping plate 5, and is fixed to the second clamping plate 5. The second pull shaft 9 is also fixed to the output shaft of the second linear motion output device 7. Furthermore, when the first linear motion output device 6 and the second linear motion output device 7 are activated, they drive the first clamping plate 4 and the second clamping plate 5 away from each other to unload the metal elbow 19.

[0056] In this embodiment of the invention, the support assembly 1 is used for structural support and assembly of components such as the stop block 2, guide shaft 3, first clamping plate 4, second clamping plate 5, first linear motion output device 6, second linear motion output device 7, first pull shaft 8, and second pull shaft 9. The stop block 2 is fixed to the support assembly 1, and an accommodating space is formed between two adjacent stop blocks 2. The accommodating space provides movement space for a set of first clamping plates 4 and second clamping plates 5. The guide shaft 3 is horizontally oriented, passing through the stop block 2, and both ends of the guide shaft 3 are fixed to the support assembly 1. The first clamping plate 4 and the second clamping plate 5 are arranged opposite each other and cooperate to form a clamping assembly to clamp and position the metal elbow 19, thereby facilitating the cutting of the metal elbow 19.

[0057] Each accommodating space is equipped with a set of clamping components. Regarding the first clamping plate 4 and the second clamping plate 5, the first clamping plate 4 is sleeved on the guide shaft 3, and the second clamping plate 5 is also sleeved on the guide shaft 3. That is, the first clamping plate 4 can slide along the guide shaft 3 under the action of an external force, and the second clamping plate 5 can also slide along the guide shaft 3 under the action of an external force. This allows the first clamping plate 4 and the second clamping plate 5 to move towards each other (also known as moving closer together) or move away from each other (also known as moving further apart).

[0058] Both the first linear motion output device 6 and the second linear motion output device 7 can output linear motion. That is, the component fixed to the output shaft of the linear motion output device can be driven to perform synchronous linear motion when the linear motion output device is working. The first linear motion output device 6 and the second linear motion output device 7 can be located on opposite sides of the support assembly 1. For example, the first linear motion output device 6 can be fixed to the first side of the support assembly 1, and the second linear motion output device 7 can be fixed to the second side of the support assembly 1. The first side and the second side are opposite to each other. For example, the first side can be the left side, and the second side can be the right side.

[0059] The first pull shaft 8 passes sequentially through the stop block 2, the first clamping plate 4, and the second clamping plate 5, and is fixed to the first clamping plate 4. Furthermore, the first pull shaft 8 is fixed to the output shaft of the first linear motion output device 6. Since the position of the stop block 2 is fixed, when the first linear motion output device 6 extends or retracts, it drives the first pull shaft 8, which is fixed to the output shaft, to move synchronously. This, in turn, drives at least one first clamping plate 4, which is fixed to the first pull shaft 8, to move linearly along the guide shaft 3 towards or away from the second clamping plate 5 located in the same accommodating space.

[0060] The second pull shaft 9 passes sequentially through the stop block 2, the first clamping plate 4, and the second clamping plate 5, and is fixed to the second clamping plate 5. The second pull shaft 9 is fixedly connected to the output shaft of the first linear motion output device 6. Since the position of the stop block 2 remains constant, when the second linear motion output device 7 extends or retracts, it drives the second pull shaft 9, which is fixed to the output shaft, to move synchronously. This, in turn, drives at least one second clamping plate 5, which is fixed to the second pull shaft 9, to move linearly along the guide shaft 3 towards or away from the first clamping plate 4 located in the same accommodating space.

[0061] The fixing methods mentioned in the embodiments of this invention may include, but are not limited to, threaded connections, welding, screws, and flange connections, etc., and are not further limited here. The linear motion output device may include, but is not limited to, cylinders, electric cylinders, and other linear actuators.

[0062] In summary, when positioning of metal elbows 19 is required, at least one metal elbow 19 to be cut can be pre-positioned and placed in the space between the first clamping plate 4 and the second clamping plate 5. Then, the first linear motion output device 6 and the second linear motion output device extend respectively, causing the first clamping plate 4 and the second clamping plate 5, located in the same accommodating space, to approach each other and cooperate in clamping the metal elbow 19, thus completing the positioning of at least one metal elbow 19. At this time, the positioning and unloading device is in the clamping state and can cut the metal elbow 19. After cutting all the metal elbows 19, the first linear motion output device 6 and the second linear motion output device 7 can retract respectively, causing the first clamping plate 4 and the second clamping plate 5, located in the same accommodating space, to move away from each other. At this time, the synchronous unloading of at least one metal elbow 19 is completed, and the positioning and unloading device is in the unloading state. Therefore, by switching from the clamping state to the unloading state through the positioning and unloading device, the positioning and unloading of multiple metal elbows 19 can be realized simultaneously, which greatly improves the processing efficiency of the metal elbows 19.

[0063] As a preferred embodiment, four sets of first clamping plates 4 and second clamping plates 5 can be provided. Those skilled in the art can determine the specific number of first clamping plates 4 and second clamping plates 5 according to the production cycle, without making any further limitations here.

[0064] An optional embodiment of the invention, referring to... Figure 6 and Figure 7 As shown, the first clamping plate 4 has a first positioning groove 401, and the second clamping plate 5 has a second positioning groove 501. When the first clamping plate 4 and the second clamping plate 5 are in surface contact, the clamping cavity formed by the first positioning groove 401 and the second positioning groove 501 is in clearance fit with the metal elbow 19.

[0065] In this embodiment of the invention, to improve the positioning accuracy of the metal elbow 19, a first positioning groove 401 is formed on the first clamping plate 4, and a second positioning groove 501 is formed on the second clamping plate 5. When the first clamping plate 4 and the second clamping plate 5 approach each other until they form surface contact, the clamping cavity formed by the first positioning groove 401 and the second positioning groove 501 is clearance-fitted with the metal elbow 19. That is, the radial cross-section of the metal elbow 19 is adapted to the cross-sectional shape of the clamping cavity along the radial direction of the metal elbow 19, thereby improving the clamping stability and positioning accuracy of the metal elbow 19. This can prevent the metal elbow 19 from vibrating during cutting, thus avoiding the problem of unevenness at the cut metal end. For example, the cross-sectional shape of the first positioning groove 401 along the radial direction of the metal elbow 19 and the cross-sectional shape of the second positioning groove 501 along the radial direction of the metal elbow 19 are both half-circles. The cross-sectional shape of the first positioning groove 401 along the axial direction of the metal elbow 19 and the cross-sectional shape of the second positioning groove 501 along the axial direction of the metal elbow 19 can be U-shaped or arc-shaped, respectively.

[0066] An optional embodiment of the invention, referring to... Figure 1-7 As shown, the positioning and ejection device may further include a first ejection block 10 and a first ejection spring 11. The first ejection block 10 is disposed completely through the first clamping plate 4 and extends into the first positioning groove 401. The first ejection spring 11 is sleeved on the first ejection block 10 and abuts against the first clamping plate 4. When the first clamping plate 4 and the second clamping plate 5 clamp the metal elbow 19, the first ejection spring 11 is in its normal state. When the first clamping plate 4 and the second clamping plate 5 move away from each other, the first ejection block 10, under external pressure, moves closer to the first positioning groove 401 to push the metal elbow 19 out of the first positioning groove 401.

[0067] In this embodiment of the invention, the first ejector block 10 completely penetrates the first clamping plate 4, meaning that both ends of the first ejector block 10 extend beyond the two end faces of the first clamping plate 4. One end of the first ejector block 10 extends into the first positioning groove 401. The first ejector spring 11 is fitted onto the first ejector block 10 and abuts against the first clamping plate 4. The end of the first ejector block 10 near the first ejector spring 11 may have a folded edge, which, together with the folded edge on the end face of the first clamping plate 4 away from the first positioning groove 401, limits the axial movement of the first ejector spring 11.

[0068] When the first clamping plate 4 and the second clamping plate 5 form surface contact and clamp the metal elbow 19, due to the abutment action of the metal elbow 19 against the first ejector block 10, the first ejector block 10 makes a linear movement away from the first positioning groove 401. The distance between the end face of the first clamping plate 4 away from the first positioning groove 401 and the folded edge on the first ejector block 10 becomes longer. At this time, the first ejector spring 11 is in normal state.

[0069] When the first clamping plate 4 and the second clamping plate 5 move away from each other in a linear motion, the first ejector block 10, under the external pressure of the first clamping plate 4, moves towards the first positioning groove 401. The end of the first ejector block 10 near the first positioning groove 401 extends into the first positioning groove 401, and the first ejector spring 11 changes from its normal state to a compressed state. This allows the metal elbow 19 located in the first positioning groove 401 to be quickly extended out of the first positioning groove 401. This avoids the problem of the metal elbow 19 getting stuck in the first positioning groove 401 and needing to be manually removed. It also improves the ejection efficiency of multiple metal elbows 19. Furthermore, when the first clamping plate 4 and the second clamping plate 5 move towards each other in a linear motion again, the first ejector spring 11, through its reset action, drives the first ejector block 10 to move away from the first positioning groove 401 in a linear motion, thereby preventing the first ejector block 10 from affecting the clamping of the metal elbow 19.

[0070] An optional embodiment of the invention, referring to... Figure 6 and Figure 7 As shown, the positioning and ejection device may further include a second ejection block 12 and a second ejection spring 13. The second ejection block 12 is disposed completely through the second clamping plate 5 and extends into the second positioning groove 501. The second ejection spring 13 is sleeved on the ejection block and abuts against the second clamping plate 5. When the first clamping plate 4 and the second clamping plate 5 clamp the metal elbow 19, the second ejection spring 13 is in its normal state. When the first clamping plate 4 and the second clamping plate 5 move away from each other, the second ejection block 12, under external pressure, moves closer to the second positioning groove 501 to push the metal elbow 19 out of the second positioning groove 501.

[0071] In this embodiment of the invention, the second ejector block 12 completely penetrates the second clamping plate 5, meaning that both ends of the second ejector block 12 extend beyond the two end faces of the second clamping plate 5. One end of the second ejector block 12 extends into the second positioning groove 501. The second ejector spring 13 is fitted onto the second ejector block 12 and abuts against the second clamping plate 5. The end of the second ejector block 12 near the second ejector spring 13 may have a folded edge, which, together with the folded edge on the end face of the second clamping plate 5 away from the second positioning groove 501, limits the axial movement of the second ejector spring 13.

[0072] When the second clamping plate 5 and the second clamping plate 5 form surface contact and clamp the metal elbow 19, due to the abutment action of the metal elbow 19 on the second ejector block 12, the second ejector block 12 makes a linear movement away from the second positioning groove 501, and the distance between the end face of the second clamping plate 5 away from the second positioning groove 501 and the folded edge on the second ejector block 12 becomes longer. At this time, the second ejector spring 13 is in normal state.

[0073] When the second clamping plate 5 and the second clamping plate 5 move away from each other in a linear motion, the second ejector block 12, under the external pressure of the second clamping plate 5, moves in a linear motion towards the second positioning groove 501. The end of the second ejector block 12 near the second positioning groove 501 extends into the second positioning groove 501. Furthermore, the second ejector spring 13 changes from its normal state to a compressed state, thereby allowing the metal elbow 19 located in the second positioning groove 501 to quickly extend out of the second positioning groove 501. This avoids the problem of the metal elbow 19 getting stuck in the second positioning groove 501 and requiring manual removal, and improves the ejection efficiency of multiple metal elbows 19. Moreover, during the next linear motion of the first clamping plate 4 and the second clamping plate 5 moving closer to each other, the reset action of the second ejector spring 13 drives the second ejector block 12 to move in a linear motion away from the second positioning groove 501, thereby preventing the second ejector block 12 from affecting the clamping of the metal elbow 19.

[0074] In some embodiments, the first ejector block 10 and the second ejector block 12 are respectively provided with trajectory grooves, and the positioning ejector device may further include a locking member 18. The locking member 18 is embedded in the trajectory groove, and the locking member 18 embedded in the first ejector block 10 is fixedly connected to the first clamping plate 4, and the locking member 18 embedded in the second ejector block 12 is fixedly connected to the second clamping plate 5. Thus, the horizontal sliding trajectory of the first ejector block 10 and the second ejector block 12 can be limited by the cooperation between the locking member 18 and the trajectory groove.

[0075] An optional embodiment of the invention, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, with a set of first clamping plates 4 and second clamping plates 5, the positioning and ejection device includes a first abutment 14 and a second abutment 15. The first abutment 14 and the second abutment 15 are respectively mounted on the support assembly 1. When the first clamping plate 4 and the second clamping plate 5 are far apart, the first abutment 14 presses against the first ejection block 10, and the second abutment 15 presses against the second ejection block 12.

[0076] In this embodiment of the invention, the first abutment member 14 is fixed to the support assembly 1 and is positioned opposite the end of the first ejector block 10 away from the first positioning groove 401. Thus, even when the first clamping plate 4 and the second clamping plate 5 are far apart, the first abutment member 14 forms a pressure contact with the first ejector block 10. The abutting force generated by the first abutment member 14 on the first ejector block 10 drives the first ejector block 10 to move linearly closer to the first positioning groove 401, causing one end of the first ejector block 10 to extend out of the first positioning groove 401, thereby pushing the metal elbow 19 out of the first positioning groove 401 and causing it to fall, completing the ejection operation.

[0077] The second abutment member 15 presses against the second ejector block 12, and the abutment force generated by the second abutment member 15 on the second ejector block 12 drives the second ejector block 12 to make a linear movement close to the second positioning groove 501, causing one end of the second ejector block 12 to extend out of the second positioning groove 501. This pushes the metal elbow 19 out of the second positioning groove 501, causing it to fall and complete the ejection operation.

[0078] In an optional embodiment of the invention, when at least two sets of first clamping plates 4 and second clamping plates 5 are provided, the positioning and ejection device includes a first abutment 14 and a second abutment 15. The first abutment 14 and the second abutment 15 are respectively mounted on the support assembly 1. When the first clamping plate 4 and the second clamping plate 5 are far apart, the first abutment 14 presses against the first ejection block 10 located at the first side edge, and the second abutment 15 presses against the second ejection block 12 located at the second side edge. Furthermore, the first ejection block 10 on the first clamping plate 4 and the second ejection block 12 on the second clamping plate 5, which are arranged opposite to each other, press against each other.

[0079] In this embodiment of the invention, when at least two sets of first clamping plates 4 and second clamping plates 5 are provided, the difference from the above-described embodiment is that the first ejector block 10 on the first clamping plate 4, located in the middle and in different accommodating spaces, and the second ejector block 12 on the second clamping plate 5, will form mutual pressure contact when the first linear motion output device 6 and the second linear motion output device 7 operate to eject materials. Thus, through the mutuality of the pressure contact force, the first ejector block 10 on the first clamping plate 4, under the abutting action of the second ejector block 12, makes a linear movement closer to the first positioning groove 401, causing one end of the first ejector block 10 to extend out of the first positioning groove 401, thereby pushing the metal elbow 19 out of the first positioning groove 401 and causing it to fall out, completing the ejection operation. The second ejector block 12 on the second clamping plate 5, under the abutting action of the first ejector block 10, makes a linear movement closer to the second positioning groove 501, causing one end of the second ejector block 12 to extend out of the second positioning groove 501. This pushes the metal elbow 19 out of the second positioning groove 501, causing it to fall and complete the unloading operation.
