[0002] The lead screw is an ideal product for converting rotary motion into linear motion, or converting linear motion into rotary motion. It is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or to convert torque into axial repetitive force. It has the characteristics of high precision, reversibility and high efficiency. Due to its very small friction resistance, the lead screw is widely used in various industrial equipment and precision instruments, including the lead screw for the discharge port of the self-lubricating buffer bin.

[0003] Normally, support seats are required to support the upper and lower ends of the screw rod. At the same time, in order to ensure the stability of the screw rod's rotation, bearings need to be installed at the connection between the screw rod and the support seat to connect them to each other, and the screw rod is connected to the inner ring of the bearing. After long-term use, the ball inside the bearing may be damaged due to wear. At this time, the bearing may not be able to rotate freely due to the damage of the ball. The existing bearings mainly weld the outer ring to the surface of the base, which makes the bearing more cumbersome when installing or disassembling. The operator cannot quickly install or disassemble the bearing, which affects the operator's use.

[0004] Therefore, a self-lubricating buffer bin discharge port screw seat is proposed. Utility Model Content

[0009] Further preferably, slots are provided on the inner sides of the inner cavities of the first cavities, and the two insert blocks penetrate the inner cavities of the two slots and extend into the inner cavities of the two jacks.

[0010] Further preferably, the bottoms of the inner cavities of the two first cavities are each provided with a sliding groove, and the bottoms of the four sliding blocks are each slidably connected to the inner cavities of the two sliding grooves.

[0015] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0016] First, the utility model sets up an installation mechanism. When the bearing needs to be installed, the pull block is pulled to move to both sides. At this time, the slider moves outward synchronously with it. The connecting rod flips inward due to the movement of the slider, and pulls the installation plate inward to move. At this time, the installation plate drives the plug block to move inward synchronously, so that the plug block moves out of the inner cavity of the installation groove. As the installation plate moves, the hard spring is deformed by the force. Then, after the bearing is clamped in the inner cavity of the installation groove, the pull block is released. At this time, the hard spring is deformed again due to the disappearance of the force, and the plug block is deformed again through Its own tension pushes the mounting plate to move inward. At this time, the connecting rod flips outward due to the movement of the mounting plate, and drives the slider, the pull block and the splicing block to move inward synchronously. The plug-in block is plugged into the inner cavity of the socket through the movement of the mounting plate, thereby completing the installation of the bearing. The installation method is relatively flexible and simple, and it is fixed by plugging. It can also effectively prevent the outer ring of the bearing from rotating when it is installed in the inner cavity of the mounting groove. Compared with the welding method, it can effectively improve the convenience of operators in installing or disassembling the bearing, and facilitate the use of operators.

[0017] Second, the utility model can limit the moving direction of the mounting plate by providing a moving groove to prevent it from shaking up and down when moving, thereby affecting the installation of the bearing; by providing a slot, the insert block can be limited to prevent the insert block from shifting in direction when moving, thereby affecting the installation or removal of the bearing; by providing a sliding groove, the movement of the slider can be limited to prevent the slider from rotating on the surface of the slide rod when moving, thereby affecting the fixing of the bearing; by providing a sliding groove, the moving direction of the pull block can be limited to prevent the pull block from shifting in the moving direction when pulling the pull block to install the bearing, thereby causing The problem of bearing being unable to be installed normally occurs. By setting the slot and the hole, since they are in the same horizontal direction, the plug block can freely enter and exit the inner cavity of the hole and the slot without being blocked by other objects, thereby improving the passability of the plug block. By setting the limit bolt, the splicing block can be limited to avoid interference from external factors, which causes the splicing block to drive the pulling block to move, thereby causing the bearing to fall off from the inner cavity of the installation groove and affect the normal installation of the bearing. By setting the clamping block, the position of the bearing placed in the inner cavity of the installation groove can be limited, so that the slot and the hole can be in the same horizontal direction, which is convenient for the installation of the bearing through the plug block.

DETAILED DESCRIPTION

[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, the embodiment of the utility model provides a self-lubricating buffer bin discharge port screw seat, including a base 1, a mounting groove 6 is provided at the middle end of the base 1, a bearing 3 is provided in the inner cavity of the mounting groove 6, a clamping groove 5 is provided on both the front and rear sides of the bearing 3, and a socket 4 is provided on both the left and right sides of the bearing 3;

[0030] The left and right sides of the inner surface of the base 1 are provided with mounting mechanisms 2, and the mounting mechanisms 2 include a first cavity 201 and a second cavity 202. The first cavity 201 is opened on the left and right sides of the inner surface of the base 1, and the second cavity 202 is opened on the front and back sides of the left and right sides of the inner surface of the base 1. The inner cavities of the two first cavities 201 are fixedly installed with sliding rods 203, and the front and back sides of the surfaces of the two sliding rods 203 are slidably connected with sliders 204. The inner sides of the four sliders 204 are movably connected with connecting rods 205, and the inner sides of the four connecting rods 205 are movably connected with mounting plates 206. The inner sides of the two mounting plates 206 are fixedly installed with plug blocks 207, and the outer sides of the four sliders 204 are fixedly installed with pull blocks 209. The front and back sides of the outer sides of the two mounting plates 206 are fixedly connected with hard springs 208, and the outer sides of the four hard springs 208 are fixedly connected to the outer sides of the inner cavities of the four second cavities 202.

[0031] By setting the installation mechanism 2, when the bearing 3 needs to be installed, the pull block 209 is pulled to move to both sides, and the slider 204 moves synchronously to the outside with it. The connecting rod 205 is flipped inward due to the movement of the slider 204, and the installation plate 206 is pulled inward to move. At this time, the installation plate 206 drives the plug block 207 to move inward synchronously, so that the plug block 207 moves out of the inner cavity of the installation groove 6. As the installation plate 206 moves, the hard spring 208 is deformed by the force. Then, after the bearing 3 is clamped in the inner cavity of the installation groove 6, the pull block 209 is released. At this time, the hard spring 208 is deformed again due to the disappearance of the force, and The mounting plate 206 is pushed to move inward by its own tension. At this time, the connecting rod 205 is flipped outward due to the movement of the mounting plate 206, and drives the slider 204, the pull block 209 and the splicing block 214 to move inward synchronously. The plug block 207 is plugged into the inner cavity of the socket 4 through the movement of the mounting plate 206, thereby completing the installation of the bearing 3. The installation method is relatively flexible and simple, and it is fixed by plugging. It can also effectively prevent the outer ring of the bearing 3 from rotating when it is installed in the inner cavity of the mounting groove 6. Compared with the use of welding, it can effectively improve the convenience of the operator in installing or disassembling the bearing 3, and facilitate the use of the operator.

[0032] Example 2

[0033] In one embodiment, the front and rear sides of the inner cavities of the two first cavities 201 are provided with movable grooves 210, the front and rear sides of the two mounting plates 206 penetrate the inner cavities of the four movable grooves 210 and extend into the inner cavity of the second cavity 202, the inner side of the inner cavity of the first cavity 201 is provided with a slot 211, the two plug blocks 207 penetrate the inner cavities of the two slots 211 and extend into the inner cavities of the two jacks 4, the bottom of the inner cavities of the two first cavities 201 is provided with a sliding groove 213, the bottoms of the four sliders 204 are slidably connected in the inner cavities of the two sliding grooves 213, and the base 1 is provided with a slide groove 212 on both sides, four pull blocks 209 penetrate the inner cavity of the two slide grooves 212 and extend to the outside of the base 1, the two slots 211 and the two sockets 4 are in the same horizontal direction, and the slots 211 and the sockets 4 are connected to each other, and the outer sides of the four pull blocks 209 are fixedly installed with a splicing block 214, the four splicing blocks 214 are spliced ​​with each other, and the tops of the four splicing blocks 214 are threadedly connected with limiting bolts 215, and the front and rear sides of the inner cavity of the installation groove 6 are fixedly installed with a clamping block 7, and the two clamping blocks 7 are clamped in the inner cavity of the two clamping slots 5.

[0034] By setting the moving groove 210, the moving direction of the mounting plate 206 can be limited to prevent it from shaking up and down when moving, thereby affecting the installation of the bearing 3. By setting the slot 211, the insert block 207 can be limited to prevent the insert block 207 from shifting in direction when moving, thereby affecting the installation or removal of the bearing 3. By setting the sliding groove 213, the movement of the slider 204 can be limited to prevent the slider 204 from rotating on the surface of the slide rod 203 when moving, thereby affecting the fixing of the bearing 3. By setting the sliding groove 212, the moving direction of the pull block 209 can be limited to prevent the pull block 209 from shifting in the moving direction when the pull block 209 is pulled to install the bearing 3, thereby causing the shaft to be disassembled. The problem that the bearing 3 cannot be installed normally arises. By setting the slot 211 and the hole 4, since they are in the same horizontal direction, the plug block 207 can freely enter and exit the inner cavity of the hole 4 and the slot 211 without being blocked by other objects, thereby improving the passability of the plug block 207. By setting the limiting bolt 215, the splicing block 214 can be limited to avoid the interference of external factors, which causes the splicing block 214 to drive the pulling block 209 to move, thereby causing the bearing 3 to fall off from the inner cavity of the installation groove 6 and affect the normal installation of the bearing 3. By setting the clamping block 7, the position of the bearing 3 placed in the inner cavity of the installation groove 6 can be limited, so that the slot 211 and the hole 4 can be in the same horizontal direction, which is convenient for the installation of the bearing 3 through the plug block 207.

[0035] The utility model is in operation: when the bearing 3 needs to be installed, first pull the pull block 209 to move to both sides, at this time the slider 204 moves synchronously outward with it, the connecting rod 205 flips inward due to the movement of the slider 204, and pulls the mounting plate 206 inward to move, at this time the mounting plate 206 drives the plug block 207 to move inward synchronously, so that the plug block 207 moves out of the inner cavity of the mounting groove 6, and as the mounting plate 206 moves, the hard spring 208 is deformed by the force, and then the bearing 3 is clamped in the mounting groove 6. After it is in the inner cavity, the pull block 209 is released. At this time, the hard spring 208 is deformed again due to the disappearance of the force, and pushes the mounting plate 206 to move inward through its own tension. At this time, the connecting rod 205 is flipped outward due to the movement of the mounting plate 206, and drives the slider 204, the pull block 209 and the splicing block 214 to move inward synchronously. The plug block 207 is plugged into the inner cavity of the socket 4 through the movement of the mounting plate 206, and then the limit bolt 215 is rotated to limit the position of the splicing block 214, thereby completing the installation of the bearing 3.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
