Description

Technical Field

[0001] This utility model relates to the field of machine tool manufacturing technology, specifically a positioning mechanism for machine tool manufacturing. Background Technology

[0002] Machine tools are machines used to manufacture machines, also known as machine tools or machine tools. They are generally classified into metal cutting machine tools, forging and pressing machine tools, and woodworking machine tools. In modern mechanical manufacturing, there are many methods for processing mechanical parts. In addition to cutting, there are casting, forging, welding, stamping, extrusion, etc. However, parts with high precision requirements and fine surface roughness requirements generally need to be finally processed by cutting methods on machine tools.

[0003] In the processes of punching, forging, and grinding on machine tools, it is necessary to clamp and position the raw materials to facilitate processing. Currently, some clamping and positioning devices require changing the corresponding clamping and positioning device when processing different raw materials. There are clamping and positioning devices for round tubes and clamping and positioning devices for square tubes. Changing the clamping and positioning device is very time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a positioning mechanism for machine tool manufacturing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for machine tool manufacturing, including a base, and further comprising:

[0006] A fixed seat and a movable seat are symmetrically arranged on the outer side of the base. A first limiting pawl and a second limiting pawl are symmetrically rotatably mounted on the outer side of both the fixed seat and the movable seat. A first gear is provided on the outer side of both the first limiting pawl and the second limiting pawl, and the first gears on the first limiting pawl and the second limiting pawl mesh with each other.

[0007] An adjustment assembly is installed on the outside of the movable seat to drive the first gear, thereby driving the first and second limiting claws to rotate. A bracket is fixedly connected to the outside of the movable seat, and a second gear is rotatably installed inside the bracket. A toothed plate that meshes with the second gear is provided on the outside of the base.

[0008] Preferably, the adjustment assembly includes a worm gear fixedly mounted on the outside of the first gear, a worm gear meshing with the outside of the worm gear and a worm mounted on the outside of the movable seat, a first servo motor fixedly connected to the outside of the movable seat, and the worm fixedly mounted on the output end of the first servo motor.

[0009] Preferably, a second servo motor is fixedly connected to the outside of the bracket, and the second gear is fixedly installed on the output end of the second servo motor.

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

[0015] This invention uses a second servo motor to drive a second gear to rotate. The second gear meshes with a gear plate, causing a bracket to move on a base. The bracket then moves a movable seat on the base. The distance between the movable seat and the fixed seat is adjusted to a suitable position. The part is then placed between the first and second limiting claws on the fixed and movable seats. Next, the first servo motor drives a worm gear to rotate, which in turn drives a worm wheel to rotate. The worm wheel then drives the first gear on its outer side to rotate. The two first gears mesh and rotate, causing the first and second limiting claws to move closer together until the part is clamped between the two limiting claws, thus holding and limiting the part on the base. The distance between the first and second limiting claws can be adjusted according to the size of the part, making it applicable to a wide range of situations. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4 As shown, a positioning mechanism for machine tool manufacturing includes a base 1, and further includes: a fixed seat 2 and a movable seat 3 symmetrically arranged on the outer side of the base 1. The fixed seat 2 is fixedly installed at the bottom of the base 1, and the movable seat 3 is slidably installed at the top of the base 1. A first limiting pawl 4 and a second limiting pawl 5 are symmetrically rotatably installed on the outer side of both the fixed seat 2 and the movable seat 3. A first gear 6 is provided on the outer side of both the first limiting pawl 4 and the second limiting pawl 5, and the first gear 6 on the first limiting pawl 4 and the second limiting pawl 5 meshes with each other. The rotation of the first gear 6 drives the first limiting pawl 4 and the second limiting pawl 5 to rotate. An adjustment component 7 is installed on the outer side of the movable seat 3 to drive the first gear 6, thereby driving the first limiting pawl 4 and the second limiting pawl 5 to rotate. A bracket 8 is fixedly connected to the outer side of the movable seat 3. A second gear 9 is rotatably installed inside the bracket 8. A toothed plate 10 that meshes with the second gear 9 is provided on the outer side of the base 1.

[0023] The adjusting assembly 7 includes a worm gear 701 fixedly mounted on the outside of the first gear 6. The worm gear 701 is fixedly mounted on the outside of the first gear 6 on the second limiting pawl 5, and the worm gear 701 and the first gear 6 rotate synchronously. A worm 702 mounted on the outside of the movable seat 3 meshes with the outside of the worm gear 701. A first servo motor 703 is fixedly connected to the outside of the movable seat 3, and the worm 702 is fixedly mounted on the output end of the first servo motor 703. The first servo motor 703 drives the worm 702 to rotate, which in turn drives the worm gear 701 to rotate. The worm gear 701 drives the first gear 6 on its outside to rotate. The two first gears 6 mesh and rotate with each other, thereby causing the first limiting pawl 4 and the second limiting pawl 5 to move closer or further apart.

[0024] A second servo motor 11 is fixedly connected to the outside of the bracket 8, and a second gear 9 is fixedly installed on the output end of the second servo motor 11. The second servo motor 11 drives the second gear 9 to rotate, and the second gear 9 meshes with the gear plate 10, which drives the bracket 8 to move on the base 1. The bracket 8 drives the movable seat 3 to move on the base 1. The distance between the movable seat 3 and the fixed seat 2 can be adjusted to accommodate parts of different lengths.

[0025] The movable base 3 has two symmetrically arranged sliding grooves 12 inside. The top of the base 1 is fixedly connected to two sliders 13 that are adapted to the sliding grooves 12. The sliders 13 are engaged inside the sliding grooves 12. The movable base 3 is limited to the base 1 by sliding the sliders 13 in the sliding grooves 12, and can move freely.

[0026] Rubber pads 15 for increasing friction are fixedly connected to the outer sides of both the first limiting claw 4 and the second limiting claw 5. The rubber pads 15 protect the surface of the part and improve the clamping stability of the part. Support blocks 14 are fixedly connected to the outer sides of both the first limiting claw 4 and the second limiting claw 5. The support blocks 14 on each set of the first limiting claw 4 and the second limiting claw 5 are arranged upside down. The two staggered support blocks 14 will not affect the first limiting claw 4 and the second limiting claw 5 from getting closer to each other, and can also support the part.

[0027] Working principle: When positioning a part, the distance between the fixed seat 2 and the movable seat 3 is adjusted according to the length of the part. Specifically, the second servo motor 11 drives the second gear 9 to rotate, and the second gear 9 meshes with the gear plate 10, causing the bracket 8 to move on the base 1. The bracket 8 then moves the movable seat 3 on the base 1, adjusting the distance between the movable seat 3 and the fixed seat 2 to a suitable position. The part is then placed between the first limiting claw 4 and the second limiting claw 5 on the fixed seat 2 and the movable seat 3. Next, the first servo motor 703 drives the worm gear 702 to rotate, which in turn drives the worm wheel 701 to rotate. The worm wheel 701 drives the first gear 6 on its outer side to rotate, and the two first gears 6 mesh and rotate, thereby causing the first limiting claw 4 and the second limiting claw 5 to move closer together until the part is clamped between the two limiting claws, thus clamping and limiting the part on the base 1. The distance between the first limiting claw 4 and the second limiting claw 5 can be adjusted according to the size of the part, making it applicable to a wide range of situations.
