Abstract
The utility model discloses a lead screw adjusting device, its characterized in that: the motor-driven screw rod mounting device comprises a mounting rack, the motor is installed to the mounting rack, motor drive connects one and controls the lead screw, the one end of a left side dextrorotation lead screw is connected with first nut, and the other end is connected with the second nut, sliding connection has first slide and second slide on the mounting rack, first nut rotates and connects on first slide, the second nut rotates and connects on the second slide. The utility model discloses replaced and need adopt two sets of motors and two sets of lead screws just can realize the mode of the opposite movement or the opposite movement of slide in the past, had with low costs, the high technological effect of synchronism.
Description
Technical Field
The utility model relates to an adjusting device's technical field, concretely relates to lead screw adjusting device.
Background
In the center of the prior art, two sets of motors of two lead screws are generally used for controlling an up-down moving mode of two sliding seats, so as to form an up-down structure. However, the mechanism has the disadvantages that two sets of screw rods and two sets of motors are required, the cost is high, and because one screw rod is controlled by the two motors respectively, the up-and-down motion synchronism of the slide seat is poor due to inevitable difference, and the production and the manufacture of products are influenced.
SUMMERY OF THE UTILITY MODEL
In view of the not enough of background art, the utility model provides a lead screw adjusting device, the technical problem of its solution is how to realize the opposite directions or the reverse synchronous motion of slide with lower cost's structure.
For solving the technical problem, the utility model provides a following technical scheme:
lead screw adjusting device, including the mounting bracket, the motor is installed to the mounting bracket, motor drive connects about the lead screw, the one end of a left side dextrorotation lead screw is connected with first nut, and the other end is connected with the second nut, sliding connection has first slide and second slide on the mounting bracket, first nut rotates to be connected on first slide, the second nut rotates to be connected on the second slide.
Be equipped with parallel arrangement's first slide rail and second slide rail on the mounting bracket, the one end sliding connection of first slide is in on the first slide rail, other end sliding connection is in on the second slide rail, the one end sliding connection of second slide is in on the first slide rail, other end sliding connection is in on the second slide rail.
Compared with the prior art, the utility model beneficial effect who has is: the utility model discloses replaced and need adopt two sets of motors and two sets of lead screws just can realize the mode of the opposite movement or the opposite movement of slide in the past, had with low costs, the high technological effect of synchronism.
Drawings
The utility model discloses there is following figure:
FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic view of fig. 1 from another perspective.
Detailed Description
As shown in the figures, the screw rod adjusting device in the embodiment comprises a mounting frame 1, a motor 2 is mounted on the mounting frame 1, the motor 2 is connected with a left-right screw rod 3 in a transmission way, the left-hand screw rod 3 has left-hand screw thread at one end and right-hand screw thread at the other end, and the first nut 4 is connected with one end of the left-hand screw rod 3 and the second nut 5 is connected with the other end, therefore, when the left and right spinning rods 3 are driven by the motor 2 to rotate, the first nuts 4 and the second nuts 5 of the left and right spinning rods 3 can move oppositely or reversely and synchronously, the mounting frame 1 is connected with the first sliding seat 6 and the second sliding seat 7 in a sliding mode, the first nuts 4 are connected to the first sliding seat 6 in a rotating mode, the second nuts 5 are connected to the second sliding seat 7 in a rotating mode, and specifically, the first nuts 4 and the first sliding seat 6 and the second nuts 5 and the second sliding seat 7 can be connected through bearings.
In the present embodiment, the first carriage 6 and the second carriage 7 are slidably connected to the mounting frame 1 in the following manner: be equipped with parallel arrangement's first slide rail 8 and second slide rail 9 on the mounting bracket 1, the one end sliding connection of first slide 6 is on first slide rail 8, and other end sliding connection is on second slide rail 9, and the one end sliding connection of second slide 7 is on first slide rail 8, and other end sliding connection is on second slide rail 9.
To sum up, the utility model discloses replaced and need adopted two sets of motors and two sets of lead screws just can realize the mode of the opposite movement or the opposite movement of slide in the past, had with low costs, the high technological effect of synchronism.
