Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to a tooling fixture for a CNC lathe. Background Technology

[0002] A CNC lathe is a type of lathe that uses computer numerical control technology for machining. It is widely used in the machining industry. By controlling the movement of the cutting tool through a computer program, it can achieve precise cutting and shaping of various materials. With the rapid development of modern manufacturing, CNC lathes have been widely used in the machining field due to their high efficiency and precision machining capabilities. In the machining process of a CNC lathe, the tooling fixture is an important component connecting the workpiece and the machine tool. Its design and performance directly affect the machining efficiency and product quality. Therefore, a tooling fixture for CNC lathes is required.

[0003] Traditional CNC lathes typically use bolts and nuts to secure the fixtures to the lathe. This method of installation and disassembly is time-consuming and reduces work efficiency. Furthermore, traditional fixtures are usually designed for workpieces of specific sizes, lacking flexibility. When machining workpieces of different sizes or shapes, different fixtures often need to be changed. This not only increases the inventory requirements for fixtures and increases production costs but also reduces the practicality of the equipment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a tooling fixture for CNC lathes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tooling fixture for a CNC lathe includes a CNC lathe body. L-shaped plates are fixed at the four corners of the top of the CNC lathe body. A common base is provided on the inner sidewall of each of the four L-shaped plates. Circular holes are provided at the four corners of the sidewall of the base. A snap-fit ​​mechanism for engaging the base is provided on the outer sidewall of each of the four L-shaped plates. A U-shaped plate is provided on both sides of the top of the base. A first moving mechanism for moving two U-shaped plates is provided on the top of the base. Two second sliders are slidably connected to the inner sidewall of each of the two U-shaped plates. A mechanism for moving one of the two second bidirectional lead screws is provided on the outer sidewall of each of the two slide blocks. The device includes a second moving mechanism for the two second sliders, and U-shaped plates fixed to the inner walls of the four second sliders. Each of the four U-shaped plates has a clamping mechanism for holding the workpiece. During use, the first moving mechanism moves the two U-shaped plates closer or further apart, and the second moving mechanism moves the two second sliders closer or further apart, thus adjusting the position of the four U-shaped plates. Combined with the clamping mechanisms, it can clamp and fix workpieces of different sizes without requiring fixture replacement, saving production costs and improving the practicality of the device.

[0007] Preferably, the snap-fit ​​mechanism includes a sleeve, which is disposed through the inner wall of one of the L-shaped plates. A circular slider is slidably connected to the inner wall of the L-shaped plate. A column is fixed to one end of the circular slider, and the column passes through the outer wall of one end of the sleeve. The column is adapted to one of the circular holes. A pull rod is fixed to the other end of the circular slider, and the pull rod passes through the outer wall of the other end of the sleeve. A spring is sleeved on the side wall of the pull rod. Connecting plates are provided at both ends of the top of the CNC lathe body. The two ends of the two connecting plates are respectively fixed to two of the pull rods. A handle is fixed to the outer wall of each of the two connecting plates. Two handles, in conjunction with two connecting plates, pull the four levers apart in pairs, thereby pulling the four circular sliders apart in pairs along the inner walls of the four sleeves until the four pillars retract into the four sleeves. At this point, all four springs are compressed. Then, place the base into the four L-shaped plates. Release the two handles, and the reaction force of the four compressed springs will push the four circular sliders in the opposite direction until the four pillars are pushed into the four circular holes. This completes the installation of the clamp without the need for bolts and nuts. The operation is simple, saves time, and improves work efficiency.

[0008] Preferably, the first moving mechanism includes a second slide groove, which is located at the middle of the top of the CNC lathe body. A first bidirectional lead screw is rotatably connected inside the second slide groove. Two first lead screw nuts are symmetrically sleeved on the sidewalls of the first bidirectional lead screw, and both first lead screw nuts are adapted to the first bidirectional lead screw. The two first lead screw nuts are respectively fixed to two U-shaped plates. First slide grooves are provided at both ends of the top of the base. Slide rods are fixed to the inner sidewalls of the two first slide grooves. Two first sliders are symmetrically sleeved on the sidewalls of the two slide rods. The four first sliders are respectively fixed to the bottom ends of the two U-shaped plates. A first motor is fixed to the outer sidewall of the base, and the output shaft of the first motor is fixed to the first bidirectional lead screw. The first motor drives the first bidirectional lead screw to rotate, thereby causing the two first lead screw nuts to move closer or further away from each other. Under the constraint of the two slide rods and the four first sliders, the two U-shaped plates move closer or further away from each other, thereby causing the four U-shaped plates to move closer or further away from each other in the left-right direction along the top of the CNC lathe body.

[0009] Preferably, the second moving mechanism includes two support plates, which are symmetrically fixed to both ends of the outer wall of one of the U-shaped plates. The inner walls of the two support plates are rotatably connected to the same second bidirectional lead screw. The side wall of the second bidirectional lead screw is symmetrically fitted with two second lead screw nuts, and both second lead screw nuts are adapted to the second bidirectional lead screw. The two second lead screw nuts are respectively fixed to two of the second sliders. A second motor is fixed to the outer wall of one of the support plates, and the output shaft of the second motor is fixed to the second bidirectional lead screw, driving the two second motors to rotate simultaneously. In conjunction with the two second lead screw nuts, the two U-shaped plates move closer to each other or further away from each other. That is, the four U-shaped plates move closer to each other or further away from each other in pairs along the front-back direction of the top of the CNC lathe body.

[0010] Preferably, the clamping mechanism includes clamping plates, which are slidably disposed on the inner sidewall of one of the U-shaped plates. A threaded rod is rotatably connected to the top of the U-shaped plate and passes through the top of one of the U-shaped plates. A threaded hole is opened on the top of one of the U-shaped plates, and the threaded hole and the threaded rod are adapted to each other. The four corners of the workpiece are respectively placed into the four U-shaped plates, and the four threaded rods are rotated to drive the four clamping plates to move downward along the inner sidewall of the four U-shaped plates until the four clamping plates are in close contact with the workpiece, thereby completing the workpiece fixing work.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During use, four L-shaped plates are symmetrically fixed to the top of the CNC lathe body in advance, and two U-shaped plates are installed on the top of the base. Through the design of the snap-fit ​​mechanism, the snap-fit ​​work of the base can be completed quickly, that is, the installation of the fixture is completed. There is no need to use bolts and nuts for fixing. The operation is simple, saves time, and improves work efficiency.

[0013] 2. By using the first moving mechanism to move the two U-shaped plates closer or further apart, and in conjunction with the second moving mechanism to move the two second sliders closer or further apart, the position of the four U-shaped plates can be adjusted. With the clamping mechanism, workpieces of different sizes can be clamped and fixed without changing the fixtures, saving production costs and improving the practicality of the device.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-6 A tooling fixture for a CNC lathe includes a CNC lathe body 1. L-shaped plates 2 are fixed at the four corners of the top of the CNC lathe body 1. The inner walls of the four L-shaped plates 2 are provided with the same base 3. Circular holes 12 are provided at the four corners of the side walls of the base 3. The outer walls of the four L-shaped plates 2 are provided with snap-fit ​​mechanisms for snapping the base 3. Rectangular plates 4 are provided on both sides of the top of the base 3. A first moving mechanism for moving two of the rectangular plates 4 is provided on the top of the base 3. Two second sliders 24 are slidably connected to the inner walls of the two rectangular plates 4. The outer walls of the two second bidirectional lead screws 21 are provided with mechanisms for moving two of the second sliders 24. The second moving mechanism of the two sliders 24 has U-shaped plates 25 fixed to the inner walls of each of the four second sliders 24. Each of the four U-shaped plates 25 has a clamping mechanism for clamping functional workpieces. During use, the first moving mechanism drives the two U-shaped plates 4 to move closer or further apart, and the second moving mechanism drives the two second sliders 24 to move closer or further apart, thereby adjusting the position of the four U-shaped plates 25. With the clamping mechanism, workpieces of different sizes can be clamped and fixed without changing the fixtures, saving production costs and improving the practicality of the device.

[0023] Furthermore, the snap-fit ​​mechanism includes a sleeve 5, which is disposed through the inner wall of one of the L-shaped plates 2. A circular slider 8 is slidably connected to the inner wall of the L-shaped plate 2. A column 9 is fixed to one end of the circular slider 8, and the column 9 passes through the outer wall of one end of the sleeve 5. The column 9 is adapted to one of the circular holes 12. A pull rod 10 is fixed to the other end of the circular slider 8, and the pull rod 10 passes through the outer wall of the other end of the sleeve 5. A spring 11 is sleeved on the side wall of the pull rod 10. Connecting plates 6 are provided at both ends of the top of the CNC lathe body 1. The two ends of the two connecting plates 6 are respectively fixed to two of the pull rods 10. Handles 7 are fixed to the outer walls of the two connecting plates 6. 7. With the two connecting plates 6, pull the four levers 10 away from each other in pairs, thereby pulling the four circular sliders 8 away from each other along the inner walls of the four sleeves 5 in pairs, until the four pillars 9 are retracted into the four sleeves 5. At this time, the four springs 11 are all in a compressed state. Then, place the base 3 into the four L-shaped plates 2. At this time, release the two handles 7. Under the reaction of the four compressed springs 11, push the four circular sliders 8 to move in the opposite direction until the four pillars 9 are pushed into the four circular holes 12. This completes the installation of the fixture. There is no need to fix it by locking with bolts and nuts. The operation is simple, saves time, and improves work efficiency.

[0024] Furthermore, the first moving mechanism includes a second slide groove 17, which is located at the top center of the CNC lathe body 1. A first bidirectional lead screw 18 is rotatably connected inside the second slide groove 17. Two first lead screw nuts 19 are symmetrically sleeved on the side walls of the first bidirectional lead screw 18, and both first lead screw nuts 19 are adapted to the first bidirectional lead screw 18. The two first lead screw nuts 19 are respectively fixed to two U-shaped plates 4. A first slide groove 13 is provided at both ends of the top of the base 3. A slide rod 14 is fixed to the inner side wall of each of the two first slide grooves 13. Two slide rods 14 are symmetrically sleeved on the side walls of each of the two slide rods 14. The first slider 15, four first sliders 15 are respectively fixed to the bottom ends of the two U-shaped plates 4. The first motor 16 is fixed to the outer wall of the base 3, and the output shaft of the first motor 16 is fixed to the first bidirectional lead screw 18. The first motor 16 drives the first bidirectional lead screw 18 to rotate, thereby driving the two first lead screw nuts 19 to move closer or further away from each other. Under the restriction of the two slide rods 14 and the four first sliders 15, the two U-shaped plates 4 move closer or further away from each other, thereby driving the four U-shaped plates 25 to move closer or further away from each other in the left and right direction of the top of the CNC lathe body 1.

[0025] Furthermore, the second moving mechanism includes two support plates 20, which are symmetrically fixed to both ends of the outer wall of one of the U-shaped plates 4. The inner walls of the two support plates 20 are rotatably connected to the same second bidirectional lead screw 21. The side wall of the second bidirectional lead screw 21 is symmetrically fitted with two second lead screw nuts 22, and both second lead screw nuts 22 are adapted to the second bidirectional lead screw 21. The two second lead screw nuts 22 are respectively fixed to two of the second sliders 24. A second motor 23 is fixed to the outer wall of one of the support plates 20, and the output shaft of the second motor 23 is fixed to the second bidirectional lead screw 21. The two second motors 23 drive the two second bidirectional lead screws 21 to rotate simultaneously, which, together with the two second lead screw nuts 22, drives the two U-shaped plates 25 to move closer to each other or further away from each other. That is, the four U-shaped plates 25 move closer to each other or further away from each other in the front-back direction of the top of the CNC lathe body 1.

[0026] Furthermore, the clamping mechanism includes clamping plates 26, which are slidably disposed on the inner side wall of one of the U-shaped plates 25. A threaded rod 27 is rotatably connected to the top of the U-shaped plate 25, and the threaded rod 27 passes through the top of one of the U-shaped plates 25. A threaded hole is opened on the top of one of the U-shaped plates 25, and the threaded hole and the threaded rod 27 are adapted to each other. The four corners of the workpiece are placed into the four U-shaped plates 25 respectively, and the four threaded rods 27 are rotated to drive the four clamping plates 26 to move downward along the inner side wall of the four U-shaped plates 25 respectively, until the four clamping plates 26 are all in close contact with the workpiece, thus completing the workpiece fixing work.

[0027] Working Principle: During operation, four L-shaped plates 2 are symmetrically fixed to the top of the CNC lathe body 1, and two U-shaped plates 4 are installed on the top of the base 3. When installing the fixture, the two handles 7, in conjunction with the two connecting plates 6, pull the four pull rods 10 apart, causing the four circular sliders 8 to move apart along the inner walls of the four sleeves 5 until the four pillars 9 are retracted into the four sleeves 5. At this point, the four springs 11 are compressed. The base 3 is then placed inside the four L-shaped plates 2. Releasing the two handles 7 causes the four circular sliders 8 to move in the opposite direction under the reaction force of the four compressed springs 11, until the four pillars 9 are pushed into the four circular holes 12. This completes the fixture installation without the need for bolts and nuts. The operation is simple, saves time, and improves work efficiency. When clamping a workpiece, the distance between the four U-shaped plates 25 is adjusted according to the workpiece size. To adjust, the power switch of the first motor 16 is first turned on, driving the first motor 16 to drive the first bidirectional lead screw 18. The rotation causes the two first lead screw nuts 19 to move closer or further apart. Under the constraint of the two slide rods 14 and the four first sliders 15, the two U-shaped plates 4 move closer or further apart, which in turn causes the four U-shaped plates 25 to move closer or further apart in pairs along the left-right direction of the top of the CNC lathe body 1. At the same time, the power switches of the two second motors 23 are turned on, driving the two second motors 23 to drive the two second bidirectional lead screws 21 to rotate simultaneously. In conjunction with the two second lead screw nuts 22, the two U-shaped plates 25 move closer or further apart in pairs along the front-back direction of the top of the CNC lathe body 1. In this way, workpieces of different sizes can be clamped and fixed without changing the fixture, saving processing costs and improving the practicality of the device. When clamping the workpiece, the four corners of the workpiece are placed into the four U-shaped plates 25 respectively, and the four threaded rods 27 are rotated to drive the four clamping plates 26 to move downward along the inner sidewalls of the four U-shaped plates 25 respectively, until the four clamping plates 26 are in close contact with the workpiece, thus completing the workpiece fixing work.

[0028] 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.
