Description
Technical Field
[0001] This utility model relates to the field of cutting technology, and in particular to a cutting fixture that is easy to position. Background Technology
[0002] Positioning fixtures are tools or equipment used in machining to ensure the precise position and orientation of workpieces. When cutting parts, workers usually first use positioning fixtures to stably position and clamp the parts before cutting them with a cutting machine.
[0003] However, existing cutting fixtures that are easy to position can generally only clamp devices with planar surfaces. When clamping devices with curved surfaces, the contact area between the clamping plane of the clamping plate and the device is often small, which makes it impossible to clamp the curved device stably, affecting subsequent cutting operations.

[0018] 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.
[0019] This utility model provides, for example Figure 1-4The cutting fixture shown includes a mounting box 2 fixedly mounted on the top of a mounting plate 1. A dual-axis motor 3 is fixedly mounted inside the mounting box 2. Rotating screws 4 are fixedly mounted on the two output shafts of the dual-axis motor 3, and both rotating screws 4 are rotatably connected to the inner wall of the mounting box 2. To rotatably mount the rotating screws 4 onto the mounting box 2, rotating grooves are respectively formed on the inner walls of both sides of the mounting box 2. The two ends of the two rotating screws 4 extend into the two rotating grooves and are respectively fixedly fitted with rotating bearings. The outer rings of the two rotating bearings are fixedly connected to the inner wall of the rotating grooves. The rotating bearings make the rotating screws 4 rotate more stably on the mounting box 2. Connecting plates 5 are threaded onto the two rotating screws 4 respectively. Both connecting plates 5 are slidably connected to the mounting box 2, and the tops of both connecting plates 5 extend outside the mounting box 2. Frame plates 6 are fixedly installed on the tops of the two connecting plates 5 respectively. To place the components to be cut and facilitate clamping of the components, a U-shaped placement plate 11 is fixedly installed on the top of the mounting box 2. The U-shaped placement plate 11 passes through the two frame plates 6 and is movably connected to them. Arc-shaped clamping plates 7 are fixedly installed on the tops of the two frame plates 6 respectively. Openings are provided on the two arc-shaped clamping plates 7, and rectangular clamping plates 10 are slidably installed in the two openings. The dual-axis motor 3 rotates to drive the two rectangular clamping plates 10 to position and clamp the planar components. The outer walls of the two arc-shaped clamping plates 7 are divided into... Two U-shaped plates 8 are fixedly installed. Each U-shaped plate 8 has two adjustment ports 14. Adjustment plates 9 are slidably installed on each U-shaped plate 8 and are fixedly connected to two arc-shaped clamping plates 7. Two second slots 13 and two first slots 12 are respectively provided at the top and bottom of each adjustment plate 9. Fixed rods 15 are fixedly installed in each of the four adjustment ports 14. Moving plates 18 are slidably installed on each of the four fixed rods 15. To reduce the service life of the fixed rods 15 and thus the moving plates 18, and to improve the service life of the fixed rods 15, through holes are provided on each of the four moving plates 18. Linear bearings are fixedly installed in each of the four through holes. Four linear bearings are slidably connected to the inner walls of the four linear bearings. Each of the four movable plates 18 is fixedly mounted with a locking rod 19, and one end of each locking rod 19 extends into the corresponding second locking groove 13. First, the two movable plates 18 are moved away from each other, causing the locking rod 19 to move out of the second locking groove 13. Then, the two adjusting plates 9 are moved away from each other, so that the first locking groove 12 moves to the same vertical position as the locking rod 19. The movable plates 18 are released, and under the action of the compression spring 16, the locking rod 19 is pushed to move into the first locking groove 12 to hold the adjusting plate 9, so that the rectangular clamping plate 10 is stably held in the position next to the arc-shaped clamping plate 7. The two arc-shaped clamping plates 7 are driven to move closer to each other by the dual-axis motor 3 to position and clamp the curved surface device.
[0020] In order to keep the locking rod 19 in the second locking groove 13 to hold the adjusting plate 9 without being subjected to other external forces, compression springs 16 are movably sleeved on the four fixed rods 15 respectively, and one end of the four compression springs 16 is fixedly connected to the corresponding moving plate 18, and the other end of the four compression springs 16 is fixedly connected to the inner wall of the corresponding adjusting port 14 respectively.
[0021] In order to protect the compression springs 16 and prevent external dust from adhering to them and affecting their service life, protective telescopic bellows 17 are movably sleeved on each of the four compression springs 16. One end of each of the four protective telescopic bellows 17 is fixedly connected to the corresponding movable plate 18, and the other end of each of the four protective telescopic bellows 17 is fixedly connected to the inner wall of the corresponding adjustment port 14.
[0022] The working principle of the easy-to-position cutting fixture provided by this utility model is as follows: In the initial state, the compression spring 16 is in a compressed state. The compression spring 16 keeps one end of the clamping rod 19 in the second clamping groove 13 to hold the adjusting plate 9, thereby making the rectangular clamping plate 10 flush with the arc-shaped clamping plate 7. When it is necessary to cut a flat surface device, the flat surface device is placed on the U-shaped placement plate 11, and the dual-axis motor 3 is started. The rotation of the dual-axis motor 3 drives the two rotating screws 4 to rotate. The rotation of the screws 4 drives the two connecting plates 5 to move closer to each other. The two connecting plates 5 move closer to each other, which drives the two frame plates 6 and the rectangular clamping plate 10 to move closer to each other, so that the two rectangular clamping plates 10 position, clamp and fix the flat surface device, thereby facilitating cutting. When it is necessary to position and clamp curved parts for subsequent cutting operations, firstly, move the two moving plates 18 away from each other, causing the clamping rod 19 to move out of the second clamping slot 13. Then, move the two adjusting plates 9 away from each other, so that the first clamping slot 12 moves to the same vertical position as the clamping rod 19. At this moment, the rectangular clamping plate 10 is just outside the arc-shaped clamping plate 7. Release the moving plates 18, and then push the clamping rod 19 into the first clamping slot 12 under the action of the compressed spring 16 to clamp the adjusting plate 9. This keeps the rectangular clamping plate 10 stably in a position next to the arc-shaped clamping plate 7. Then, start the dual-axis motor 3 to drive the two arc-shaped clamping plates 7 to move closer to each other to position and clamp the curved parts, keeping the curved parts stably in the current position, which is convenient for subsequent cutting operations.
[0023] Compared with related technologies, the easy-to-position cutting fixture provided by this utility model has the following beneficial effects:
[0024] This utility model provides a cutting fixture for easy positioning. Flat surfaces are placed on a U-shaped placement plate 11. A dual-axis motor 3 rotates, driving two rectangular clamping plates 10 to position and hold the flat surfaces, facilitating subsequent cutting operations. When positioning and clamping curved surfaces is required, two moving plates 18 are first moved away from each other, causing the clamping rod 19 to move out of the second clamping slot 13. Then, two adjusting plates 9 are moved away from each other, moving the first clamping slot 12 to the same vertical position as the clamping rod 19. The moving plates 18 are released, and under the action of the compression spring 16, the clamping rod 19 is pushed into the first clamping slot 12 to hold the adjusting plate 9, keeping the rectangular clamping plate 10 stably positioned next to the arc-shaped clamping plate 7. The dual-axis motor 3 drives the two arc-shaped clamping plates 7 to move closer together to position and clamp the curved surfaces, keeping them stably in their current position, facilitating subsequent cutting operations.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
