[0009] Furthermore, a slider is slidably installed on the T-block, and two L-shaped support blocks are threadedly installed on the top of the slider. Round blocks are respectively provided on the two L-shaped support blocks, and wire reels are fixedly installed on the sides of the two round blocks close to each other. Both the two wire reels are communicated with the two L-shaped support blocks, and both the two wire reels are threadedly connected to the lead screw.

[0010] Furthermore, springs are wound on the outer walls of the two wire drums, and ends of the springs that are away from each other are fixedly connected to the two round blocks respectively.

[0011] Furthermore, two threaded rods are threadedly installed on the two L-shaped support blocks, and two nuts are threadedly installed on the outer walls of the two threaded rods respectively, and the sides of the two corresponding nuts close to each other are in contact with the two L-shaped support blocks.

[0012] Furthermore, the clamping mechanism includes a support plate threadedly mounted on the top of two L-shaped support blocks, two rectangular plates are fixedly mounted on the top of the support plate, round rods are respectively slidably mounted on the two rectangular plates, and clamping blocks are respectively fixedly mounted on the sides of the two round rods close to each other.

[0015] The utility model has the following beneficial effects:

[0016] (1) The utility model sets an adjustment mechanism. First, the nut is screwed into the screw. Then, the nut is moved so that the round block on it is engaged with an L-shaped support block on the slider. Next, a spring is inserted into the outer wall of the nut, and another nut is screwed in so that the two nuts match and clamp the spring. After clamping, another L-shaped support block is clamped on the round block of the nut that is screwed in last. Then, the two L-shaped support blocks are fixed by using a threaded rod and a nut. This arrangement can prevent the two nuts from generating a gap when moving. After all adjustments are made, the motor is started. The motor will drive the screw to rotate, thereby driving the two nuts to rotate, so that the spring is subjected to pressure. The tension of the spring makes one of the nuts close to the left tooth surface of the screw and the other nut close to the right tooth surface of the screw, thereby eliminating the gap between the two. The nut is pushed close to the tooth surface of the screw by the spring, which not only helps to improve the adjustment efficiency, reduce the cumbersome process, and facilitate operation, but also reduces the technical requirements for the operator.

[0017] (2) The utility model provides a clamping mechanism. First, the two handles are pulled away from each other, so that the reset spring is compressed and moves the clamping block. Then, the object to be fixed is placed between the two clamping blocks, and the two handles are released. Under the action of the reset spring, the clamping blocks clamp the left and right surfaces of the object. This arrangement is conducive to keeping the object fixed and avoiding unnecessary movement or shaking during use.

[0028] See also Figure 1-5 As shown, the utility model is a mechanical slide screw gap adjustment mechanism in a modular machine tool, comprising a plurality of legs 1 and a chassis 2 fixedly mounted on the top of the plurality of legs 1, and an adjustment mechanism and a clamping mechanism are arranged on the legs 1;

[0031] Through the cooperation of multiple screw holes 7 and bolts 8, the T-block 6 can be fixed in the chassis 2, which helps to ensure that the T-block 6 is firmly fixed inside the chassis 2 and improve the structural stability and safety of the equipment.

[0032] Among them Figure 2As shown, a slider 9 is slidably installed on the T-block 6, and two L-shaped support blocks 10 are threadedly installed on the top of the slider 9. Round blocks 11 are respectively provided on the two L-shaped support blocks 10, and wire reels 12 are fixedly installed on the sides of the two round blocks 11 close to each other. The two wire reels 12 are communicated with the two L-shaped support blocks 10, and the two wire reels 12 are threadedly connected to the lead screw 5.

[0033] The clamping and fixing of the two nuts 12 by the two round blocks 11 is conducive to ensuring the stable position of the two nuts 12 and preventing them from loosening or falling off, thereby improving the reliability and stability of the device.

[0034] Among them Figure 5 As shown, springs 13 are wound around the outer walls of the two wire drums 12 , and ends of the springs 13 that are away from each other are fixedly connected to the two round blocks 11 .

[0035] The two nuts 12 are pushed tightly against the tooth surface of the lead screw 5 by the spring 13, which not only helps to improve the adjustment efficiency, reduce the cumbersome process, and facilitate the operation, but also ensures the accuracy and stability of the adjustment.

[0036] Among them Figure 5 As shown, two threaded rods 14 are threadedly installed on the two L-shaped support blocks 10 , and two nuts 15 are threadedly installed on the outer walls of the two threaded rods 14 , respectively. The sides of the two corresponding nuts 15 close to each other are in contact with the two L-shaped support blocks 10 .

[0037] Through the cooperation of the two threaded rods 14 and the multiple nuts 15, the two L-shaped support blocks 10 can fix the nuts 12, which is conducive to ensuring that the nuts 12 are fully supported and fixed, and maintaining the structural stability and safety of the equipment.

[0041] The two clamping blocks 19 can realize clamping movement through the return spring 20 on the round rod 18, which is beneficial to ensure that the clamping blocks 19 can perform clamping movement when needed, provide the required functions of the device, and return to the original position through the return spring 20 when clamping is not needed.

[0042] Among them Figure 1 As shown, a controller 22 is disposed on the right side of the chassis 2 , and two buttons 23 are disposed on the right side of the controller 22 .

[0043] Controlling the device through the controller 22 is beneficial to improving the operating efficiency, stability and convenience of production management of the device.

[0044] A specific application of this embodiment is as follows: first, screw the nut 12 into the screw 5, then move the nut 12 so that the round block 11 on it is engaged with an L-shaped support block 10 on the slider 9, then, insert the spring 13 into the outer wall of the nut 12, and screw in another nut 12 so that the two nuts 12 match and clamp the spring 13. After clamping, insert another L-shaped support block 10 into the round block 11 of the nut 12 that is screwed in last, and then use the threaded rod 14 and the nut 15 to cooperate and fix the two L-shaped support blocks 10. This arrangement can prevent the two nuts 12 from generating a gap when moving. After all adjustments are made, start the motor 4, and the motor 4 will drive the screw 5 to rotate, thereby driving the two nuts 12 to rotate, so that the spring 13 is subjected to pressure, and the tension of the spring 13 makes one of the nuts 12 is close to the left tooth surface of the screw 5, and the other nut 12 is close to the right tooth surface of the screw 5, eliminating the gap between the two. The nut 12 is pushed to be close to the tooth surface of the screw 5 by the spring 13, which is not only conducive to improving the adjustment efficiency, reducing the cumbersome process, and facilitating operation, but also can reduce the technical requirements for operators; when it is necessary to fix the object, first, pull the two handles 21 to move them away from each other, so that the reset spring 20 is compressed and the clamping block 19 is moved, and then, the object to be fixed is placed between the two clamping blocks 19, and the two handles 21 are released, so that under the action of the reset spring 20, the respective clamping blocks 19 will clamp the left and right side surfaces of the object. Through this arrangement, it is beneficial to keep the object fixed and avoid unnecessary movement or shaking during use.
