Description

Technical Field

[0001] The invention relates to the technical field of sealing ring installation, and in particular to a sealing ring installation device. Background Art

[0002] When connecting parts of machinery or industrial products, sealing is often performed through sealing rings. Products with different profiles have different assembly requirements for sealing rings.

[0003] Traditionally, sealing rings are installed into products using manpower. The time required to install sealing rings varies depending on the product structure. The average period for manual insertion of products with irregular contours is longer, and the quality of manual work is unstable. The sealing ring may not be installed properly, causing the sealing ring to flanging, which affects the sealing performance of the product and reduces the quality of the product. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of low efficiency and unstable quality of manual installation of sealing rings in the prior art, thereby providing a sealing ring installation device.

[0005] The present invention provides a sealing ring installation device, which is suitable for installing the sealing ring into a placement groove of a product to be loaded, comprising: a transfer mechanism, including a platform, and a profiling block and a pushing device arranged on the platform, the outer edge of the profiling block is the same as the edge profile of the inner side wall of the placement groove, and the pushing device is suitable for pushing away the sealing ring inserted into the profiling block; and a loading mechanism, including a transfer groove, the transfer groove is suitable for accommodating and pushing out the sealing ring from the transfer mechanism, and the transfer groove and the placement groove are docked and overlapped when the loading mechanism contacts the product to be loaded.

[0006] The ejection device is a frame body, which can be lifted and lowered on the outside of the profiling block. The ejection device has the same profile as the sealing ring inserted into the profiling block, and has a first position in which the top is flush with the outer surface of the platform, and a second position in which the sealing ring is pushed away and the top is flush with the outer surface of the profiling block.

[0007] The transfer mechanism also includes a first guard block, which is arranged on the platform and moves away from or close to the profiling block under the action of external force, and has an inner side surface with the same outer edge contour as the profiling block.

[0008] The loading mechanism comprises: a second protective block, adapted to accommodate the sealing ring from the transfer mechanism and dock with the product to be loaded;

[0009] The lifting platform moves in a vertical direction and comprises a fixed top plate receiving the second guard block.

[0010] The second protection block includes:

[0011] The outer protective block includes a top plate and a side plate constituting a cavity open downward, wherein the side plate is provided with a positioning groove facing away from the lifting platform opening;

[0012] An inner enclosure plate is disposed in the cavity and fixedly connected to the top plate, and the side wall of the inner enclosure plate and the side plate constitute the transfer trough.

[0013] Fixed top plate includes:

[0014] The outer portion is arranged around the outer side of the side plate;

[0015] The engaging portion is fixedly connected to the peripheral portion, passes through the positioning groove and is engaged in the transfer groove, and is suitable for relative movement with the top plate.

[0016] The engaging portion is arranged in an annular shape and has the same outline as the ejecting device.

[0017] The sealing ring installation device also includes:

[0018] A first guide device, provided on the transfer mechanism, suitable for carrying and controlling the movement of the platform in a horizontal direction;

[0019] The second guiding device is arranged on the loading mechanism and is suitable for carrying and controlling the movement of the lifting platform in the horizontal direction.

[0020] The first guide device and the second guide device are electrically controlled guide rails.

[0021] The sealing ring installation device also includes a product placement position, which is arranged below the movement track of the lifting platform on the second guide device.

[0022] The technical solution of the present invention has the following advantages:

[0023] 1. The sealing ring installation device provided by the present invention is suitable for installing the sealing ring into the placement groove of the product to be loaded, comprising: a transfer mechanism, including a platform, and a profiling block and a push-out device arranged on the platform, the outer edge of the profiling block is the same as the edge profile of the inner side wall of the placement groove, and the push-out device is suitable for pushing away the sealing ring inserted into the profiling block; and a loading mechanism, including a transfer groove, the transfer groove is suitable for accommodating and pushing out the sealing ring from the transfer mechanism, and the transfer groove and the placement groove are docked and overlapped when the loading mechanism contacts the product to be loaded. In the prior art, there is a technology in which the sealing ring and the profiling block are moved and installed at the same time, while the profiling block and the push-out device are separately arranged, and the sealing ring is only pushed away from the profiling block. Such an arrangement has no requirements on the installation position of the sealing ring placement groove of the product, and can be applied to the situation where there is a certain distance between the sealing ring placement groove and the inner or outer wall of the product. In addition, by dividing the sealing ring installation device into a transfer mechanism and a loading mechanism, the step of inserting the contour block into the sealing ring and the step of installing the sealing ring into the placement groove are separated. The sealing ring can be installed on products to be installed at different distances and angles through the loading mechanism, thereby improving the application scope of the device, realizing the automation of sealing ring installation, and overcoming the defects of low efficiency and unstable quality of manual installation of sealing rings in the prior art.

[0024] 2. The sealing ring installation device provided by the present invention comprises a push-out device which is a frame body and is arranged outside the profiling block in a liftable manner. The push-out device has the same profile as the sealing ring inserted into the profiling block, and has a first position in which the top is flush with the outer surface of the platform, and a second position in which the top is pushed away from the sealing ring and is flush with the outer surface of the profiling block. The push-out device is arranged outside the profiling block in a liftable manner. In the first position, the top of the push-out device is flush with the outer surface of the platform. The push-out device is arranged inside the platform, and the top is the sealing ring inserted into the profiling block. When the push-out device moves from the first position to the second position, the push-out device moves upward to push the sealing ring inserted into the profiling block away from the transfer mechanism. Since the push-out device can be arranged inside the platform and has the same size as the sealing ring, such a setting reduces the volume of the device. On the other hand, the push-out device having the same profile as the side edge of the profiling block can evenly push away the sealing ring, reduce the possibility of the sealing ring flanging, disengagement and other problems, and improve product quality.

[0025] 3. The sealing ring installation device provided by the present invention, the transfer mechanism also includes a first protective block, which is arranged on the platform and moves away from or close to the profiling block under the action of external force, and has an inner side surface with the same outer edge contour as the profiling block. On the one hand, the sealing ring is pressed so that it can be installed in the transfer slot; on the other hand, when the edge of the profiling block has a concave shape, due to elastic deformation, after the sealing ring is inserted into the profiling block, there will be a gap with the edge of the concave part. The first protective block is arranged on the platform, moves toward the sealing ring and squeezes it, eliminates the gap between the sealing ring and the profiling block, and makes the sealing ring completely deformed to the same contour as the edge of the profiling block, which is convenient for the gap of the receiving mechanism to accommodate.

[0026] 4. The sealing ring installation device provided by the present invention, the fixed top plate includes: an outer portion, which is arranged around the outer side of the side plate; and a fitting portion, which is fixedly connected to the outer portion, passes through the positioning groove and is engaged in the transfer groove, and is suitable for relative movement with the top plate. The fixed top plate is arranged on the lifting platform, and receives the second protective block, and the fitting portion of the fixed top plate and the top plate on the second protective block can move relative to each other. With such an arrangement, when the second protective block transports the sealing ring to the product to be installed, the second protective block abuts against the product to be installed, and the fitting portion at the upper end of the sealing ring moves relative to the second protective block, pressing the sealing ring into the placement groove of the product to be installed. With such an arrangement, before the sealing ring is pressed into the placement groove, a step is provided for completing the docking between the transfer groove and the placement groove, thereby ensuring the accuracy and stability of the installation.

[0027] 5. The sealing ring installation device provided by the present invention has an annular fitting portion with the same profile as the ejection device. This arrangement ensures that the sealing ring is evenly stressed, and the sealing ring in the transfer tank can be evenly pressed into the placement tank, making it easier to accommodate the product to be installed, and preventing the sealing ring from being deformed, turned over or disengaged.

[0028] 6. The sealing ring installation device provided by the present invention further includes: a first guide device, which is arranged on the transfer mechanism and is suitable for carrying and controlling the horizontal movement of the platform; a second guide device, which is arranged on the loading mechanism and is suitable for carrying and controlling the horizontal movement of the lifting platform. The setting of the guide device enables the platform and the lifting platform to move in the horizontal direction, and can install and fix the sealing rings for the products to be installed at different positions, thus expanding the scope of use of the sealing ring installation device.

DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figure 1 - Figure 5 As shown, a sealing ring installation device is provided in this embodiment, which is suitable for installing the sealing ring 5 into the placement groove 41 of the product 4 to be loaded, comprising: a transfer mechanism 1, including a platform 11, and a contour block 12 and a push-out device 13 arranged on the platform 11, the outer edge of the contour block 12 is the same as the edge profile of the inner side wall of the placement groove 41, and the push-out device 13 is suitable for pushing away the sealing ring 5 inserted into the contour block 12; and a loading mechanism 3, including a transfer groove, the transfer groove is suitable for accommodating and pushing out the sealing ring 5 from the transfer mechanism 1, and the transfer groove and the placement groove 41 are docked and overlapped when the loading mechanism 3 contacts the product 4 to be loaded.

[0042] In the prior art, there is a technology that the sealing ring 5 and the profiling block 12 are moved and installed at the same time, while the profiling block 12 is separately arranged from the ejection device 13, and only the sealing ring 5 is pushed away. Such an arrangement has no requirements on the installation position of the product placement groove 41, and can be applied to the situation where there is a certain distance between the placement groove 41 and the inner or outer wall of the product. In addition, by dividing the sealing ring installation device into a transfer mechanism 1 and a loading mechanism 3, the step of inserting the profiling block 12 into the sealing ring 5 and the step of installing the sealing ring 5 into the placement groove 41 are separated, and the sealing ring 5 can be installed on the products 4 to be installed at different distances and angles through the loading mechanism 3, thereby improving the application range of the device, realizing the automation of the installation of the sealing ring 5, and overcoming the defects of low efficiency and unstable quality of manual installation of the sealing ring 5 in the prior art.

[0043] The ejection device 13 is a frame body, which can be lifted and lowered on the outside of the profiling block 12. The ejection device 13 has the same profile as the sealing ring 5 inserted into the profiling block 12, and has a first position in which the top is flush with the outer surface of the platform 11, and a second position in which the sealing ring 5 is pushed away and the top is flush with the outer surface of the profiling block 12.

[0044] The ejection device 13 is arranged on the outside of the profiling block 12 in a liftable manner. In the first position, the top of the ejection device 13 is flush with the outer surface of the platform 11. The ejection device 13 is arranged inside the platform 11, and the top is the sealing ring 5 inserted into the profiling block 12. When it moves from the first position to the second position, the ejection device 13 moves upward to push the sealing ring 5 inserted into the profiling block 12 away from the transfer mechanism 1. Since the ejection device 13 can be arranged inside the platform 11 and has the same size as the sealing ring 5, such a setting reduces the volume of the device. On the other hand, the ejection device 13 having the same side edge profile as the profiling block 12 can evenly push away the sealing ring 5, reducing the possibility of the sealing ring 5 flanging, disengagement and other problems, thereby improving product quality.

[0045] The transfer mechanism 1 further includes a first guard block 14, which is disposed on the platform 11 and has an inner side surface having the same outer edge profile as the contour block 12. The first guard block 14 is connected to an automatic telescopic device on the platform 11, and moves away from or close to the contour block 12 under the control of the transfer mechanism 1.

[0046] Such arrangement, on the one hand, compresses the sealing ring 5 so that it can be loaded into the transfer tank; on the other hand, when the edge of the profiling block 12 has a concave shape, due to elastic deformation, after the sealing ring 5 is inserted into the profiling block 12, there will be a gap with the edge of the concave part. A first protective block 14 is provided on the platform 11, which moves toward the sealing ring 5 and squeezes it to eliminate the gap between the sealing ring 5 and the profiling block 12, so that the sealing ring 5 is completely deformed into the same contour as the edge of the profiling block 12, which is convenient for the gap accommodation of the receiving mechanism.

[0047] In this embodiment, two first protective blocks 14 are provided on the inner side of the first protective block 14, and the two first protective blocks 14 form an inner side similar to the outer edge contour of the complete profiling block 12, thereby eliminating all possible gaps between the sealing ring 5 and the profiling block 12.

[0048] As a convertible embodiment, the first protection block 14 can also be one or more, and can move on the platform 11 away from or close to the gap between the existing sealing ring 5 and the contour block 12.

[0049] The loading mechanism 3 includes: a second protective block 33, which is suitable for accommodating the sealing ring 5 from the transfer mechanism 1 and docking with the product 4 to be loaded; a lifting platform 31, which moves in the vertical direction and includes a fixed top plate 36 that receives the second protective block 33.

[0050] The second protective block 33 includes: an outer protective block, including a top plate and side plates forming a cavity open downward, and the side plates are provided with positioning grooves opening away from the lifting platform 31; an inner enclosure plate 34, which is arranged in the cavity and fixedly connected to the top plate, and the side walls of the inner enclosure plate 34 and the side plates form a transfer groove.

[0051] The fixed top plate 36 includes: an outer portion 361, which is arranged around the outer side of the side plate; and an engaging portion 362, which is fixedly connected to the outer portion 361, is engaged in the transfer groove through the positioning groove, and is suitable for relative movement with the top plate.

[0052] The fixed top plate 36 is arranged on the lifting platform 31 and supports the second protective block 33, and the engaging portion 362 of the fixed top plate 36 and the top plate on the second protective block 33 can move relative to each other. With this arrangement, when the second protective block 33 conveys the sealing ring 5 to the product 4 to be loaded, the second protective block 33 abuts against the product 4 to be loaded, and the engaging portion 362 located at the upper end of the sealing ring 5 moves relative to the second protective block 33 to press the sealing ring 5 into the mounting groove 41 of the product 4 to be loaded. With this arrangement, a step for completing the docking of the transfer groove and the mounting groove 41 can be provided before the sealing ring 5 is pressed into the mounting groove 41, thereby ensuring the accuracy and stability of the installation.

[0053] The fitting portion 362 is annular and has the same profile as the ejection device 13. This arrangement ensures that the sealing ring 5 is evenly stressed, and the sealing ring 5 in the transfer groove can be evenly pressed into the placement groove 41, making it easier to accommodate the product 4 to be loaded, and preventing the sealing ring 5 from being deformed, turned over or disengaged.

[0054] As a convertible implementation, the engaging portion 362 may be partially annular and provided in multiple groups to ensure that the engaging portion 362 can receive the second guard block 33 .

[0055] The sealing ring installation device also includes: a first guide device 15, which is arranged on the transfer mechanism 1 and is suitable for carrying and controlling the platform 11 to move in the horizontal direction; a second guide device 32, which is arranged on the loading mechanism 3 and is suitable for carrying and controlling the lifting platform 31 to move in the horizontal direction. The arrangement of the guide device enables the platform 11 and the lifting platform 31 to move in the horizontal direction, and can install and fix the sealing ring 5 on the products to be installed 4 at different positions, thereby expanding the scope of use of the sealing ring installation device. In this embodiment, one second guide device 32 and one first guide device 15 are arranged respectively. As a convertible implementation method, one first guide device 15 can correspond to multiple second guide devices 32 or multiple first guide devices 15 can correspond to one second guide device 32.

[0056] The first guide device 15 and the second guide device 32 are electrically controlled guide rails. The first guide device 15 is lower than the platform 11, and the second guide device 32 is higher than the platform 11. As a convertible embodiment, the first guide device 15 and the second guide device 32 can also be pneumatic guide rails.

[0057] The sealing ring installation device also includes a product placement position 2, which is arranged below the movement track of the lifting platform 31 on the second guide device 32.

[0058] In this embodiment, the sealing ring installation device also includes a product placement position 2, on which a product 4 to be installed is placed, and the sealing ring 5 placement groove 41 of the product 4 to be installed is opened toward directly upwards. In addition, multiple positions for the product 4 to be installed are provided at the same time and can be rotated in the product placement position 2. After the sealing ring 5 of the product 4 to be installed is installed, it can be automatically rotated.

[0059] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
