Description

Technical Field

[0001] This utility model relates to the field of lead screw processing technology, specifically a lead screw seat processing and fixing base with a self-locking structure. Background Technology

[0002] Lead screws are the most commonly used transmission components in precision machinery. Their main function is to convert rotary motion into linear motion or torque into axial reciprocating force. They also feature high precision, reversibility, and high efficiency.

[0003] A fixing fixture for ball screw machining is disclosed in CN221621950U, including a base, a frame mounted on the base, a sliding assembly mounted on the frame, a clamping assembly mounted on the sliding assembly, a first clamping assembly and a second clamping assembly mounted on the frame, a placement assembly mounted on the base, and a storage box mounted on the base. The first clamping assembly and the second clamping assembly are both located above the placement assembly, and the clamping assembly moves back and forth between the storage box and the placement assembly. This fixture enables fully automatic loading, unloading, and fixing of ball screws, achieving a high degree of automation and providing stable clamping of the ball screws, preventing wobbling during further machining and ensuring the precision of ball screw machining.

[0004] During the machining process of the lead screw, the lead screw and lead screw seat need to be further assembled and installed. When the lead screw seat and lead screw are assembled together, the lead screw body needs to be clamped and fixed. A fixed base is used to maintain the stability of the lead screw. When positioning the lead screw, the existing fixed base achieves clamping and positioning of the lead screw through multi-point clamping and pressing. The clamping points are mainly concentrated in the middle area of ​​the lead screw, and there is a lack of positioning and clamping structure at the end of the lead screw. This clamping method makes the lead screw prone to rolling. When the lead screw seat is assembled, it will generate a certain torque force on the lead screw, which will cause the lead screw to roll.

[0005] Therefore, those skilled in the art have provided a screw seat machining and fixing base with a self-locking structure to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to provide a screw seat processing and fixing base with a self-locking structure, so as to solve the problem mentioned in the background art that when the existing screw seat processing and fixing base clamps the screw body, the clamping point is concentrated in the middle area of ​​the screw and the end lacks a clamping structure, which makes the screw unable to cope well with torque force.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A screw seat machining and fixing base with a self-locking structure includes: a base body, a hydraulic cylinder five fixedly installed inside the base body, a support fixedly installed at the upper end of the hydraulic cylinder five, a clamping jaw one rotatably installed at both ends of the support, a hydraulic cylinder four rotatably connected to the outer side of the clamping jaw one, a clamping jaw two installed on one side of the clamping jaw one, a hydraulic cylinder three connected to the top of the clamping jaw two, an adjusting seat slidably installed at the left end of the base body, an installation plate fixedly installed on the surface of the adjusting seat, a clamping rod rotatably connected to the surface of the installation plate, an anti-slip foot fixedly installed at the end of the clamping rod away from the installation plate, a hydraulic cylinder one installed at the center of the surface of the installation plate, and a movable connecting rod rotatably connected to the output end of the hydraulic cylinder one.

[0009] As a further embodiment of this utility model: the first gripper is rotatably connected to the support, and the first gripper is rotatably connected to the fourth hydraulic cylinder, and the lower end of the fourth hydraulic cylinder is rotatably connected to the support.

[0010] As a further improvement of this utility model, the end of the movable connecting rod away from the hydraulic cylinder is rotatably connected to the inner wall of the clamping rod.

[0011] As a further embodiment of this utility model: the hydraulic cylinder is connected to the clamping rod via a movable connecting rod, and the clamping rod is distributed in a cross shape about the symmetrical center line of the mounting plate.

[0012] As a further improvement of this utility model: the adjusting seat and the base body are a sliding structure, and a hydraulic cylinder is installed between the adjusting seat and the base body.

[0013] As a further embodiment of this utility model: rotating rods are rotatably mounted on the left and right sides of the adjusting seat, and helical gears are fixedly mounted on the surface of the rotating rods. A pin is meshed above the helical gears, and a helical groove is mounted on the surface of the pin. A drive motor is mounted on the right end of the rotating rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Clamping jaws one and two are installed in the middle area of ​​the base body. Clamping jaws one and two are arranged in opposite directions. Clamping jaws one has two sets that clamp from bottom to top, while clamping jaws two are located between the two sets of clamping jaws one and clamp from top to bottom. The clamping directions are opposite, thus clamping the lead screw body tightly and increasing the clamping force on the lead screw, avoiding clamping in the same direction, which can cause the lead screw to roll easily. An adjusting seat is slidably installed inside the lead screw seat, and an installation plate is fixedly installed on the adjusting seat. A clamping rod is rotatably installed on the installation plate. The anti-slip feet at the front end of the clamping rod improve the clamping stability of the lead screw end. The rotation is achieved by using the telescopic pull of the movable connecting rod of hydraulic cylinder one. The movable connecting rod pulls the clamping rod to unfold and retract. The clamping rod on the mounting plate clamps and fixes the end of the lead screw. An additional clamping structure is added at the end. When the lead screw seat is assembled with the other end of the lead screw, the jaws on the lead screw in different directions and the clamping at the end prevent the torque force from affecting the stability of the lead screw during assembly. At the same time, a pin is installed on the adjusting seat. The pin uses the meshing structure between the helical gear and the helical grooved bar. The pin is inserted into the positioning hole to complete the self-locking of the mounting plate, improve the automatic locking and positioning of the mounting plate at the end of the lead screw, facilitate the clamping and positioning of the end of the lead screw, and improve the stability of the assembly and processing between the lead screw and the lead screw seat.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a screw seat processing fixing base with a self-locking structure, including: a base body 1, a hydraulic cylinder 5 13 fixedly installed inside the base body 1, and a support 4 fixedly installed at the upper end of the hydraulic cylinder 5 13, a gripper 1 5 rotatably installed at both ends of the support 4, a hydraulic cylinder 4 12 rotatably connected to the outer side of the gripper 1 5, a gripper 2 6 installed on one side of the gripper 1 5, a hydraulic cylinder 3 7 connected to the top of the gripper 2 6, a rotatable connection between the gripper 1 5 and the support 4, and a rotatable connection between the gripper 1 5 and the hydraulic cylinder 4 12, and a rotatable connection between the lower end of the hydraulic cylinder 4 12 and the support 4.

[0024] Specifically, gripper 5 is connected to hydraulic cylinder 5 13 to facilitate height adjustment. Gripper 2 6 has the same structure as gripper 5, but with a different orientation. Gripper 5 has two sets of gripping from bottom to top, while gripper 2 6 is located between the two sets of grippers 5 and grips from top to bottom. The gripping directions are opposite, thus clamping the lead screw body. Hydraulic cylinders 3 7 and 5 13 adjust grippers 5 and 2 6 respectively, increasing the clamping force of the grippers on the lead screw. The grippers clamp the lead screw, and hydraulic cylinder 4 12 pulls the grippers to rotate and adjust, thus facilitating clamping and fixing of the lead screw. The hydraulic cylinders used in this device are all model 3TG-E150*1500.

[0025] An adjusting seat 2 is slidably mounted on the left end of the base body 1, and a mounting plate 3 is fixedly mounted on the surface of the adjusting seat 2. A clamping rod 8 is rotatably connected to the surface of the mounting plate 3, and an anti-slip foot 9 is fixedly mounted on the end of the clamping rod 8 away from the mounting plate 3. A hydraulic cylinder 10 is mounted at the center of the surface of the mounting plate 3. The output end of the hydraulic cylinder 10 is rotatably connected to a movable connecting rod 11. The end of the movable connecting rod 11 away from the hydraulic cylinder 10 is rotatably connected to the inner wall of the clamping rod 8. The hydraulic cylinder 10 is connected to the movable connecting rod. 11 is connected to clamping rod 8, and clamping rod 8 is distributed in a cross shape about the symmetrical center line of mounting plate 3. The adjustment seat 2 and the base body 1 are sliding structures, and a hydraulic cylinder 15 is installed between the adjustment seat 2 and the base body 1. Rotating rods 16 are rotatably installed on the left and right sides of the adjustment seat 2, and a helical gear 17 is fixedly installed on the surface of the rotating rod 16. A pin 18 is meshed on the top of the helical gear 17, and a helical groove 19 is installed on the surface of the pin 18. A drive motor 20 is installed on the right end of the rotating rod 16.

[0026] Specifically, the position of the adjusting seat 2 is adjusted according to the length of the lead screw so that the mounting plate 3 installed on the adjusting seat 2 can be close to the lead screw, thereby facilitating the clamping and fixing of the end of the lead screw. The adjusting seat 2 is moved along the base body 1 using the hydraulic cylinder 15. After the position of the adjusting seat 2 is fixed, the drive motor 20 drives the rotating rod 16 to rotate. The helical gear 17 is fixedly connected to the rotating rod 16. The helical gear 17 rotates with the rotating rod 16. The helical gear 17 has a meshing structure with the helical bar 19, thereby driving the helical bar 19 to rotate and move forward. The oblique bar 19 and the pin 18 are fixedly connected, which pushes the pin 18 to move outward. The pin 18 will be inserted into the positioning hole 14 on the inner wall of the base body 1 to position the adjusting seat 2 and prevent the adjusting seat 2 from moving backward. The mounting plate 3 is rotatably connected to the clamping rod 8. The clamping rod 8 and the hydraulic cylinder 10 are rotatably connected to the movable connecting rod 11. When the hydraulic cylinder 10 extends or retracts, it will pull the movable connecting rod 11 to rotate. The movable connecting rod 11 will bring the clamping rod 8 to the middle, so that the anti-slip foot 9 at one end of the clamping rod 8 will be clamped and positioned at the end of the screw.

[0027] The working principle of this utility model is as follows:

[0028] When using this utility model, first place the lead screw on the base body 1. Then, according to the length of the lead screw, start the second hydraulic cylinder 15 to push the adjusting seat 2 to slide along the base body 1 to the end of the lead screw. At this time, the drive motor 20 drives the rotating rod 16 to rotate. The rotating rod 16 drives the helical gear 17 to rotate. The helical gear 17 meshes with the helical bar 19, pushing the helical bar 19 and the pin 18 forward until the pin 18 is inserted into the positioning hole 14 on the inner wall of the base body 1, thereby fixing the adjusting seat 2 and completing the self-locking position of the adjusting seat 2. Next, start the third hydraulic cylinder 7 and the fifth hydraulic cylinder 13 to adjust the height of the first gripper 5 and the second gripper 6, respectively. The clamping jaws 5 grip the lead screw from bottom to top, and the clamping jaws 6 grip the lead screw from top to bottom. The clamping directions of the two sets of jaws are opposite, which increases the clamping force on the lead screw. At the same time, the hydraulic cylinder 12 is activated to pull the clamping jaws 5 to rotate and adjust, so that the jaws clamp the lead screw more tightly. Finally, the hydraulic cylinder 10 is activated. When the hydraulic cylinder 10 extends and retracts, it pulls the movable connecting rod 11 to rotate. The movable connecting rod 11 drives the clamping rod 8 to retract to the middle. The anti-slip foot 9 at one end of the clamping rod 8 clamps and positions the end of the lead screw, thereby clamping and fixing the lead screw from the end, improving the clamping stability of the lead screw, and greatly improving the efficiency and accuracy of the assembly and processing of the lead screw seat and the lead screw.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
