DETAILED DESCRIPTION

[0067] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description below refers to the accompanying drawings, which show, by way of example, specific embodiments with which the application can be practiced. The following detailed description is not intended to limit the scope of the application, as claimed, but is merely representative of some embodiments consistent with the principles of the application.

[0068] The technical solutions of the embodiments of the application and how the technical solutions of the embodiments of the application solve the problems at present will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the embodiments of the application will be described below with reference to the drawings.

[0069] Please refer to Figures 1-5 The application provides a support reaction force device for positioning and supporting a tray; the support reaction force device comprises:

[0070] a lifting mechanism 1, a jacking mechanism 2, at least one upper cushion block 3, and at least one reaction force mechanism 4;

[0071] The lifting mechanism 1 is used for bearing the tray and positioning the tray;

[0072] The jacking mechanism 2 is connected with the bottom of the lifting mechanism 1, and the jacking mechanism 2 is used for controlling the lifting mechanism 1 to move in the vertical direction;

[0073] The upper cushion block 3 is fixed on the lifting mechanism 1;

[0074] One of the upper cushion blocks 3 corresponds to one of the reaction force mechanisms 4, and the reaction force mechanism 4 is used for contacting the upper cushion block 3 when the lifting mechanism 1 is jacked up by the jacking mechanism 2; the reaction force mechanism 4 is used for providing reaction force support to the tray through the upper cushion block 3.

[0075] The application supports the tray through the lifting mechanism 1, controls the lifting mechanism 1 to move in the vertical direction through the jacking mechanism 2, and thus controls the lifting and lowering of the tray; the reaction force mechanism 4 contacts the upper cushion block 3, so that the reaction force mechanism 4 supports the lifting mechanism 1 through the upper cushion block 3, and the lifting mechanism 1 can be positioned at a specified height for a long time, avoiding the situation that the jacking mechanism 2 is jacked up for too long, ensuring the stability of the lifting mechanism 1 supporting the tray, and reducing the pressure on the jacking mechanism 2 caused by the lifting mechanism 1 and the tray, ensuring the service life of the jacking mechanism 2.

[0076] In a preferred embodiment, the lifting mechanism 1 comprises a lifting plate 11, at least one positioning pad 12 and at least one positioning pin 13.

[0077] At least one positioning pad 12 is fixed on the upper surface of the lifting plate 11 respectively; the positioning pad 12 is used to support the tray;

[0078] The positioning pin 13 is used to pass through the tray and insert into the support plate, and the positioning pin 13 is used to position the tray.

[0079] In this example, the lifting plate 11 is used to support the tray, and the positioning pad 12 is used to position the tray to avoid shaking and moving of the tray during movement.

[0080] Optionally, the positioning pad 12 is made of rubber, so that the positioning pad 12 brings greater friction to the tray, which helps to position the tray.

[0081] At least one positioning pin 13 comprises a rhombic pin and a circular pin.

[0082] The rhombic pin is a common mechanical connecting piece, mainly used to connect two parts to enable relative movement or fixed together. The rhombic pin is composed of a rhombic pin handle and two pin seats, and the pin seats are respectively embedded in the two connected parts. The main function of the rhombic pin is to transmit shear force, so it is widely used in mechanical transmission. The advantages of the rhombic pin are reliable connection and fastening, good self-locking performance, and not easy to loosen. And easy to install, no additional fastening tools are needed. However, due to the structural characteristics of the rhombic pin, the shear force transmitted by the rhombic pin has a greater impact on the parts, and proper design and calculation are required to ensure the reliability and service life of the connection.

[0083] The cylindrical pin is a common mechanical connecting piece, and the main function of the cylindrical pin is to connect two parts to enable relative movement or fixed together. The cylindrical pin is usually composed of a cylindrical pin handle and two pin seats, and the pin seats are respectively embedded in the two connected parts. Unlike the rhombic pin, the cylindrical pin mainly transmits positive axial force and pressure, and is suitable for connecting parts with high requirements, such as high-speed rotating parts. The advantage of the cylindrical pin is that it transmits force evenly and does not have too much impact on the parts, so its service life is longer.

[0084] The square pin is mainly used to transmit shear force and has good self-locking performance, and is suitable for occasions that require reliable fastening. The cylindrical pin is mainly used to transmit positive axial force and pressure, and is suitable for connecting parts with high requirements, such as high-speed rotating parts. Therefore, in mechanical design and manufacturing, it is necessary to select appropriate connecting parts according to actual needs to ensure the reliability and service life of the machine. Therefore, at least one square pin and at least one cylindrical pin are provided to meet the needs of different applications in different scenarios for different trays.

[0085] In a preferred embodiment, when the number of counterforce mechanisms 4 is one, the counterforce mechanism 4 is located on one side of the jacking mechanism 2.

[0086] When the number of counterforce mechanisms 4 is two, the two counterforce mechanisms 4 are symmetrically arranged on both sides of the jacking mechanism 2.

[0087] When the number of counterforce mechanisms 4 is greater than or equal to three, the counterforce mechanisms 4 are equidistantly arranged around the jacking mechanism 2.

[0088] In this example, when the counterforce mechanism 4 is one, the distance between the center point of the counterforce mechanism 4 and the center point of the jacking mechanism 2 does not exceed the preset distance threshold, so as to avoid the lifting plate 11 in the lifting mechanism 1 being tilted due to the counterforce mechanism 4 being too far from the jacking mechanism 2.

[0089] When the number of counterforce mechanisms 4 is two, the two counterforce mechanisms 4 are symmetrically arranged on both sides of the jacking mechanism 2, providing consistent and symmetric counterforce support for the lifting mechanism 1 and ensuring the balance of the jacking plate.

[0090] When the number of counterforce mechanisms 4 is greater than or equal to three, the counterforce mechanisms 4 are equidistantly arranged around the jacking mechanism 2, providing balanced counterforce support for the lifting plate 11 and ensuring the balance of the lifting plate 11.

[0091] In a preferred embodiment, the jacking mechanism 2 includes at least one jacking cylinder 21 and at least one jacking joint 22.

[0092] The cylinder rod of one jacking cylinder 21 is connected to the lifting mechanism 1 through one jacking joint 22, and the jacking cylinder 21 is used to control the movement of the lifting mechanism 1 in the vertical direction.

[0093] In this example, the cylinder rod of the jacking cylinder 21 is connected to the lower surface of the lifting plate 11 through the jacking joint 22.

[0094] The jacking joint 22 is arranged as a bridge connecting the cylinder rod and the lifting plate 11, and transmits the pushing force and the pulling force to the lifting plate 11, so as to facilitate replacement of the cylinder rod or the lifting plate 11, avoid damage to the lifting plate 11 caused by stress concentration due to direct connection of the cylinder rod to the lifting plate 11, and avoid difficulty in replacement of the cylinder rod and the lifting plate 11.

[0095] Meanwhile, the jacking joint 22 is also used for absorbing eccentric load and transverse load, so as to protect the cylinder and mechanical components from damage.

[0096] In a preferred embodiment, the counterforce mechanism 4 comprises a lower pad 41 and a moving mechanism 42.

[0097] The lower pad 41 is fixed to the moving mechanism 42.

[0098] The moving mechanism 42 is used for controlling the lower pad 41 to move in the horizontal direction, so that the lower pad 41 contacts and separates from the upper pad 3.

[0099] In this example, the lower pad 41 is arranged to realize contact and separation with the upper pad 3, so that when the lifting mechanism 1 needs to be supported by the counterforce, the top of the lower pad 41 contacts the bottom of the upper pad 3, so as to provide counterforce support to the lifting mechanism 1 through the upper pad 3.

[0100] When the lifting mechanism 1 does not need to be supported by the counterforce, but needs to move upward or downward, the moving mechanism 42 controls the lower pad 41 to separate from the upper pad 3, at this time, the jacking mechanism 2 can control the lifting mechanism 1 to move upward and downward.

[0101] Specifically, the upper pad 3 is fixed to the lifting plate 11 of the lifting mechanism 1, and the lower pad 41 is fixed to the moving mechanism 42.

[0102] When the jacking mechanism 2 controls the lifting mechanism 1 and the upper pad 3 to move upward, the moving mechanism 42 drives the lower pad 41 to move below the upper pad 3 and contact the bottom of the upper pad 3, so that the lower pad 41 can support the upper pad 3, thereby providing counterforce support to the lifting mechanism 1.

[0103] In a preferred embodiment, the moving mechanism 42 comprises a moving base 421 and a moving cylinder 422.

[0104] The top of the moving base 421 is in sliding connection with the bottom of the lower pad 41.

[0105] The moving cylinder 422 is connected with the moving base 421, and is used for controlling the lower pad 41 to move in the horizontal direction.

[0106] In this example, the mobile base 421 is provided as a platform that can move horizontally to provide support for the lower pad 41 to provide counterforce support for the upper pad 3.

[0107] The mobile cylinder 422 is provided to provide horizontal power for the movement of the lower pad 41.

[0108] The cylinder rod of the mobile cylinder 422 is connected to the lower pad 41 through the mobile joint 423, which serves as a bridge connecting the cylinder rod and the lower pad 41, and transmits the pushing and pulling forces to the lower pad 41, so as to facilitate the replacement of the cylinder rod or the lower pad 41, avoid the direct connection of the cylinder rod to the lower pad 41, causing stress concentration and damage to the lower pad 41, and the difficulty in replacing the cylinder rod and the lower pad 41.

[0109] At the same time, the jacking joint 22 is also used to absorb eccentric load and transverse load, so as to protect the cylinder and mechanical parts from damage.

[0110] In a preferred embodiment, the structure of the lower pad 41 is L-shaped;

[0111] The top of the vertical part of the lower pad 41 is used to contact the bottom of the upper pad 3;

[0112] The bottom of the horizontal part of the lower pad 41 is movably connected to the mobile base 421;

[0113] The vertical part of the lower pad 41 is connected to the mobile cylinder 422 away from the jacking mechanism 2.

[0114] In this example, the structure of the lower pad 41 is designed as an L-shaped structure, so that the vertical part of the L-shaped structure can contact the upper pad 3 to provide support for the upper pad 3, and at the same time, the L-shaped structure does not occupy too much space below the upper pad 3, therefore, the mobile cylinder 422 only needs to control the lower pad 41 to move a small distance, so as to realize the contact and separation between the lower pad 41 and the upper pad 3.

[0115] At the same time, the horizontal part of the L-shaped structure provides a larger contact area between the lower pad 41 and the mobile base 421, thereby ensuring the stability of the lower pad 41 and the stability and reliability of the counterforce support provided by the lower pad 41 for the upper pad 3.

[0116] In a preferred embodiment, the bottom of the lower pad 41 has at least one guide key 43;

[0117] The top of the moving base 421 has at least one guide slot 44, and at least one guide key 43 is inserted into the at least one guide slot 44 respectively, so that the lower cushion block 41 is in sliding connection with the guide base.

[0118] In this example, the guide key 43 and the guide slot 44 are arranged to enable the lower cushion block 41 to move along the axial direction of the guide key 43, thereby ensuring the stability of the moving direction of the lower cushion block 41.

[0119] In a preferred embodiment, further comprising: at least one guide shaft 5 and at least one linear bearing 6; the axial direction of the guide shaft 5 is vertical direction;

[0120] The at least one linear bearing 6 is fixed on the lifting mechanism 1 respectively;

[0121] One end of the guide shaft 5 penetrates through the linear bearing 6 and is in clearance fit or transition fit with the linear bearing 6, so that the lifting mechanism 1 moves along the axial direction of the guide shaft 5.

[0122] In this example, the guide shaft 5 and the linear bearing 6 are arranged to guide the movement of the lifting mechanism 1 in the vertical direction, thereby ensuring the reliability and stability of the moving direction of the lifting mechanism 1.

[0123] The linear bearing 6 is fixed on the lifting plate 11 of the lifting mechanism 1, and the two ends of the linear bearing 6 are communicated with the upper surface and the lower surface of the lifting plate 11.

[0124] In a preferred embodiment, further comprising a bottom plate 7;

[0125] The jacking mechanism 2 and the at least one counter-force mechanism 4 are fixed on the bottom plate 7.

[0126] Further, the end of the guide shaft 5 away from the lifting mechanism 1 is fixed on the bottom plate 7.

[0127] The jacking cylinder 21 in the jacking mechanism 2 is fixed on the upper surface of the bottom plate 7 through the cylinder cushion block 71, and the moving base 421 in the counter-force mechanism 4 is fixed on the upper surface of the bottom plate 7 through the bolt.

[0128] In this example, the bottom plate 7 is arranged to provide support for the jacking mechanism 2 and the counter-force mechanism 4.

[0129] The cylinder cushion block 71 is arranged to reduce or eliminate the influence of the jacking cylinder 21 on the bottom plate 7 during work, thereby ensuring the stability of the bottom plate 7.

[0130] The mobile base 421 is bolted on the bottom plate 7, so as to replace the counter-force mechanism 4 according to the actual situation, make the lifting mechanism 1 be positioned at different height by the different height or size of the lower cushion 41, expand the application range of the application.
