However, during installation, visual positioning often results in poor parallelism, and the installation is time-consuming and labor-intensive, which is far from meeting industrial needs. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4A screw motor guide rail positioning seat includes a base plate 1, a card slot is opened on the base plate 1, a positioning block 2 is inserted in the card slot, a moving slot is symmetrically opened on the upper end of the positioning block 2, a first slider 3 and a second slider 4 are slidably installed in the two moving slots respectively, and the side walls of the first slider 3 and the second slider 4 are in precise contact with the inner wall of the moving slot.

[0023] The size of the bottom of the positioning block 2 just matches the size of the slot, so that the positioning block 2 can be just inserted into the slot. The base plate 1 is provided with mounting holes for installing the lead screw motor and the guide rail. The first slider 3 and the second slider 4 slide in the two movable grooves respectively. Since the side walls of the first slider 3 and the second slider 4 are in precise contact with the inner walls of the movable grooves, the first slider 3 and the second slider 4 slide stably without shaking.

[0024] A first mounting block 5 is fixedly mounted on the first slider 3 , a positioning plate 6 is fixedly mounted on the first mounting block 5 , a second mounting block 7 is fixedly mounted on the second slider 4 , a positioning column 8 is fixedly mounted on the second mounting block 7 , a positioning groove 9 is formed on the lower surface of the positioning column 8 , and the positioning column 8 is parallel to the positioning plate 6 .

[0025] When installing the guide rail, insert the positioning block 2 into the slot to fix the positioning block 2, then move the first slider 3, and drive the positioning plate 6 to move through the first mounting block 5. After moving the positioning plate 6 to the specified position, place the guide rail on the base plate 1 so that the guide rail fits the side of the positioning plate 6 to ensure the parallelism between the positioning plate 6 and the guide rail. When installing the lead screw motor, move the second slider 4, and drive the positioning column 8 to move through the second mounting block 7, and insert the lead screw on the lead screw motor into the positioning groove 9 provided on the positioning column 8 to ensure that the positioning column 8 is parallel to the lead screw on the lead screw motor. Since the positioning column 8 is parallel to the positioning plate 6, the parallelism between the guide rail and the lead screw motor can be ensured. After the installation is completed, the positioning block 2 is removed from the base plate 1. The installation is time-saving and labor-saving, and meets industrial needs.

[0026] Threaded rods 10 are installed horizontally and rotatably in the two movable grooves, one ends of the two threaded rods 10 pass through the movable grooves, and are fixedly installed with adjusting blocks 11. The first slider 3 and the second slider 4 are respectively threadedly sleeved on the two threaded rods 10. When the first slider 3 and the second slider 4 need to be moved, the threaded rod 10 can be driven to rotate by rotating the adjusting block 11. The first slider 3 and the second slider 4 are threadedly sleeved on the threaded rod 10, so that when the threaded rod 10 rotates, the first slider 3 and the second slider 4 can be driven to move. At the same time, when installing the guide rail and the screw motor, the first slider 3 and the second slider 4 can be prevented from sliding, thereby avoiding displacement of the installation position.

[0027] Two L-shaped clamping blocks 12 are installed on the side of the positioning plate 6 through an elastic component. The two clamping blocks 12 are located on the side of the positioning plate 6 close to the positioning column 8. The elastic component includes two spring rods 13. The ends of the two spring rods 13 away from the positioning plate 6 are fixedly connected to the clamping blocks 12. When the guide rail is fitted with the positioning plate 6, the guide rail is placed between the clamping blocks 12 and the positioning plate 6, and then the clamping blocks 12 are contacted with the guide rail under the action of the elastic force of the spring rods 13, so that the guide rail is clamped between the clamping blocks 12 and the positioning plate 6, so as to avoid deviation of the guide rail position when fixing the guide rail, which affects the use of the screw motor guide rail.

[0028] Anti-skid pads are fixedly installed on the positioning plate 6 and the two clamping blocks 12. The anti-skid pads are located on the opposite side of the positioning plate 6 and the clamping blocks 12. When the guide rail is clamped between the positioning plate 6 and the clamping blocks 12, the anti-skid pads can increase the friction between them to prevent the guide rail from moving. The anti-skid pads are made of rubber material, so when the positioning plate 6 contacts the clamping blocks 12, they can protect the guide rail and prevent the guide rail surface from being damaged, which would affect the use of the guide rail.

[0029] Both sides of the base plate 1 are provided with sockets connected to the card slot, and both sides of the positioning block 2 are penetrated with limit holes 15, and positioning pins 14 are inserted in the two sockets, and one end of the two positioning pins 14 is inserted into the limit holes 15. When the positioning block 2 is fully inserted into the card slot, the sockets provided on the base plate 1 and the limit holes 15 provided on the side of the positioning block 2 are just aligned, and then the positioning pins 14 are inserted into the sockets and the limit holes 15, thereby limiting and fixing the positioning block 2, avoiding the position of the positioning block 2 from being offset when the screw motor and the guide rail are installed, affecting the parallelism between the screw motor and the guide rail installation.

[0030] In the utility model, when installing the guide rail, the positioning block 2 is inserted into the card slot to complete the fixing of the positioning block 2, and then the first slider 3 is moved, and the positioning plate 6 is driven to move by the first mounting block 5. After the positioning plate 6 is moved to the specified position, the guide rail is placed on the base plate 1 so that the guide rail fits with the side of the positioning plate 6 to ensure the parallelism between the positioning plate 6 and the guide rail. When installing the lead screw motor, the second slider 4 is moved, and the positioning column 8 is driven to move by the second mounting block 7, and the lead screw on the lead screw motor is inserted into the positioning groove 9 provided on the positioning column 8 to ensure that the positioning column 8 is parallel to the lead screw on the lead screw motor. Since the positioning column 8 is parallel to the positioning plate 6, the parallelism between the guide rail and the lead screw motor can be ensured. After the installation is completed, the positioning block 2 is removed from the base plate 1, and the installation is time-saving and labor-saving, meeting industrial needs.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
