Description

Technical Field

[0001] This utility model relates to the field of tool holder technology, specifically to a tool holder for lathe machining. Background Technology

[0002] A follower post is an auxiliary device that radially supports a rotating workpiece. During machining, it moves along the workpiece's axial direction together with the cutting tool. In the machining of slender shafts (length-to-diameter ratio > 20) on a lathe (including CNC lathes), the cutting force causes the workpiece to bend, affecting the machining quality. To reduce workpiece bending during machining, a follower post is needed. Patent CN217493504U, entitled "A Hydraulic Follower Post," includes a base plate, a housing, a hydraulic cylinder, connecting rods, and jaws. The housing is fixed to the base plate, and a hydraulic cylinder is mounted on the right end face of the housing. A connecting rod is hinged to each side of the piston rod end of the hydraulic cylinder, and a jaw is hinged to the other end of each connecting rod. The middle sections of the two jaws are hinged to the housing. This hydraulic follower post is controlled by a hydraulic cylinder and has high machining efficiency. However, in actual use, the hydraulic follower post is driven by a hydraulic cylinder to move the connecting rod shaft through a slider in the transverse waist hole, thereby driving the connecting rod. The connecting rod then drives the jaws hinged to the housing to open and close, clamping the shaft parts to be processed through the jaw bars in the jaw block. This increases the friction between the shaft parts and the machined parts, affecting the normal rotation of the shaft parts and easily causing wear on the shaft parts. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a lathe machining follow post.

[0004] The technical solution adopted by this utility model to solve its technical problem is a lathe machining follow post, including a support. A motor is fixed at the top of the support. The output shaft of the motor is connected to a double-acting lead screw through a coupling. Two sliders are provided in the support. Each slider has a screw hole adapted to the double-acting lead screw. A notch is provided on one side of the support for vertical movement of the two sliders. A groove is provided at the end of each slider. A base is provided in each groove. Two rollers are rotatably connected in each base. Four locking bolts are provided on one side of the support. Two screw holes adapted to the locking bolts are provided on the side walls of the two sliders and the bases.

[0005] By adopting the above technical solution, the output shaft of the motor drives the bidirectional lead screw to rotate, and the two sliders move towards each other. The distance between the two sliders can be adjusted according to the diameter of the shaft parts. The four rollers contact the shaft parts, which not only improves the stability of the shaft parts and does not affect their normal rotation, but also reduces the friction between the shaft parts and the shaft parts, thus reducing wear. Loosening the locking bolts can release the locking of the base, making it easy to remove and replace the base together with the rollers.

[0006] Specifically, a vertical rod is fixed inside the support, and both sliders are provided with through holes adapted to the vertical rod.

[0007] By adopting the above technical solution, the vertical rod configuration can improve the stability of the two sliders.

[0008] Specifically, the support has an inspection port on the side away from the notch.

[0009] By adopting the above technical solution, the installation of the inspection port facilitates the maintenance of the bidirectional lead screw inside the support.

[0010] Specifically, the inspection port is equipped with a baffle, and both sides of the baffle are integrally formed with protruding plates. Both sides of the support are provided with grooves and slots that fit the protruding plates. Each groove is provided with an insert block. The top of each of the two protruding plates is provided with a slot that fits the insert block. The top of each of the two insert blocks is fixed with a guide rod. Each of the two guide rods is fitted with a spring. Both sides of the support are provided with guide grooves for the guide rods to slide vertically.

[0011] By adopting the above technical solution, the baffle can provide a certain degree of protection for the bidirectional lead screw in the inspection port, push the two insert blocks upward, and the bottom ends of the two insert blocks disengage from the slots at the top of the two protrusions, making it convenient to remove the baffle from one side of the support.

[0012] Specifically, a base is fixed to the bottom of the support, and mounting holes are provided at the four corners of the base.

[0013] By adopting the above technical solution, the mounting holes are designed to facilitate the use of bolts to fix the base to the lathe.

[0014] The beneficial effects of this utility model are:

[0015] (1) The lathe machining follow post described in this utility model has a motor output shaft that drives a bidirectional lead screw to rotate and two sliders to move towards each other. The distance between the two sliders can be adjusted according to the diameter of the shaft part. Four rollers contact the shaft part, which not only improves the stability of the shaft part and does not affect the normal rotation of the shaft part, but also reduces the friction between the shaft part and the shaft part, and reduces the wear on the shaft part. Loosening the locking bolts can release the locking of the base, making it convenient to remove and replace the base together with the rollers.

[0016] (2) The tool holder for lathe machining described in this utility model has a baffle that can protect the bidirectional lead screw in the inspection port to a certain extent, push the two inserts to move upward, and the bottom of the two inserts disengage from the slots at the top of the two protrusions, making it convenient to remove the baffle from one side of the support.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To reduce friction in shaft-type parts during rotation, as one embodiment of this utility model, such as... Figure 1 , Figure 2 As shown, the lathe machining follow post of this utility model includes a support 1. A motor 2 is fixed to the top of the support 1 by bolts. The output shaft of the motor 2 is connected to a double-acting lead screw 10 through a coupling. Two sliders 3 are provided inside the support 1. Each slider 3 has a screw hole adapted to the double-acting lead screw 10. A notch is provided on one side of the support 1 for vertical movement of the two sliders 3. A slot is provided at the end of each slider 3. A base 5 is provided in each slot. Two rollers 6 are rotatably connected in each base 5. Four locking bolts 4 are provided on one side of the support 1. Two screw holes adapted to the locking bolts 4 are provided on the side walls of the two sliders 3 and the base 5.

[0024] In use, the output shaft of motor 2 drives the bidirectional lead screw 10 to rotate, and the two sliders 3 move towards each other. The distance between the two sliders 3 can be adjusted according to the diameter of the shaft parts, thereby adjusting the distance between the rollers 6 and the shaft parts. The four rollers 6 are in contact with the shaft parts, which not only improves the stability of the shaft parts and does not affect their normal rotation, but also reduces the friction between them and the shaft parts, thus reducing wear. Loosening the locking bolts 4 releases the locking of the base 5, making it easy to remove and replace the base 5 together with the rollers 6.

[0025] To improve the stability of slider 3, for example, such as Figure 2 As shown, a vertical rod 11 is welded and fixed inside the support 1, and both sliders 3 are provided with through holes that are adapted to the vertical rod 11.

[0026] To facilitate the maintenance of the bidirectional lead screw 10, for example, as follows: Figure 2 As shown, the support 1 has an inspection port on the side away from the notch.

[0027] To cover the access panel, for example, such as Figure 1 , Figure 3 As shown, the inspection port is provided with a baffle 7, and both sides of the baffle 7 are integrally formed with protruding plates 8. Both sides of the support 1 are provided with grooves and slots that are adapted to the protruding plates 8. Both grooves are provided with insert blocks 14. The tops of the two protruding plates 8 are provided with slots that are adapted to the insert blocks 14. The tops of the two insert blocks 14 are welded and fixed with guide rods 12. Both guide rods 12 are fitted with springs 13. Both sides of the support 1 are provided with guide grooves for the guide rods 12 to slide vertically.

[0028] When in use, the baffle 7 can cover and protect the inspection port. If the baffle 7 needs to be removed, push the two inserts 14 upwards. The bottom ends of the two inserts 14 will come out of the slots at the top of the two protrusions 8, making it easy to remove the baffle 7 from the side of the support 1.

[0029] For ease of installation, an example is provided, such as Figure 1 As shown, a base 9 is welded and fixed to the bottom end of the support 1, and mounting holes are provided at the four corners of the base 9.

[0030] In use, the base 9 is fixed to the lathe (existing technology, not shown) with bolts. The output shaft of the motor 2 drives the bidirectional lead screw 10 to rotate, and the two sliders 3 move towards each other. The distance between the two sliders 3 can be adjusted according to the diameter of the shaft part, so as to adjust the distance between the rollers 6 and the shaft part. The four rollers 6 are in contact with the shaft part, which not only improves the stability of the shaft part and does not affect the normal rotation of the shaft part, but also reduces the friction between the shaft part and the shaft part, and reduces the wear on the shaft part. Loosening the locking bolts 4 can release the locking of the base 5, making it convenient to remove and replace the base 5 together with the rollers 6.

[0031] The baffle 7 can protect the inspection port. If the baffle 7 needs to be removed, push the two inserts 14 upwards. The bottom ends of the two inserts 14 will come out of the slots at the top of the two protrusions 8, making it easy to remove the baffle 7 from the support 1 side.
