Description

Technical Field

[0001] This utility model relates to the field of vertical milling machine technology, and in particular to a vertical milling machine fixture. Background Technology

[0002] A vertical milling machine fixture is a tooling device used on a vertical milling machine. Its main function is to accurately position and firmly clamp the workpiece during the machining process, ensuring the workpiece remains stable during milling and preventing displacement or vibration due to external forces. This guarantees machining accuracy and surface quality. It consists of positioning elements, clamping devices, a fixture body, and other auxiliary components. It can be designed and adjusted according to different machining parts and process requirements, effectively improving the machining efficiency and automation level of vertical milling machines. It is widely used in the field of mechanical processing.

[0003] A search revealed Chinese Patent Publication No. CN220073995U, which discloses a vertical milling machine fixture. The fixture includes a worktable with a clamping mechanism inside and a transmission mechanism on its inner wall. A first clamping block and a first anti-slip pad enable the fixture to clamp square and round workpieces, preventing them from easily detaching. A movable baffle blocks the sliding groove at the top of the worktable, preventing waste generated during processing and saving cleaning time later. When clamping a plate-shaped workpiece, rotating the handwheel causes the threaded rod to rotate synchronously. With the cooperation of the protrusion and sliding column, the second clamping block moves smoothly up and down, placing the plate-shaped workpiece on top of the first clamping block. This process is repeated until the second clamping block contacts the plate material, thus fixing it in place. This increases the fixture's versatility. However, manual screw clamping relies on the operating force, and the clamping force varies between different batches of workpieces, causing increased surface roughness and reducing the clamping effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a vertical milling machine fixture, which aims to improve the problem in the prior art where manual screw clamping depends on the operating force, the clamping force of different batches of workpieces varies, resulting in increased surface roughness and thus reduced clamping effect.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a vertical milling machine fixture, including a machine body 1. A clamping mechanism 3 is installed in the middle of the machine body 1 for clamping the machined parts. A cleaning mechanism 2 is installed at the bottom of the machine body 1 for cleaning debris. The clamping mechanism 3 includes a mounting plate 303, which is installed in the middle of the front side of the machine body 1. A second motor 301 is installed in the middle of the front side of the mounting plate 303. The output end of the second motor 301 is fixedly connected to a drive gear 302. The installation of the second motor 301 provides power to subsequent processes. Racks 304 are slidably connected to the upper and lower ends of the inner side of the mounting plate 303. The adjacent sides of the two racks 304 are respectively meshed with the upper and lower ends of the drive gear 302. The opposite sides of the two racks 304 are far apart. All are fixedly connected with connecting rods 305. A clamping plate 307 is installed on the front side of the connecting rod 305. A fixing component 306 is installed on the outer side of the connecting rod 305. The fixing component 306 includes two first U-shaped blocks 3061. The two first U-shaped blocks 3061 are slidably connected to the outer side of the two clamping plates 307 respectively. A second U-shaped block 3062 is slidably connected to the middle of the outer side of the connecting rod 305. A locking rod 3063 is slidably connected to the rear side of the connecting rod 305. The front side of the locking rod 3063 passes through the middle of the second U-shaped block 3062 and the locking rod 3063 respectively. A support plate 9 is fixedly connected to the front end of the middle part of the machine body 1. Support rods 8 are fixedly connected to the left and right ends of the bottom of the support plate 9. The installation of the support plate 9 makes the second motor 301 more stable.

[0040] Specifically, when the second motor 301 starts, the drive gear 302 at its output end begins to rotate. The upper and lower ends of the drive gear 302 mesh with the racks 304 at the upper and lower ends of the inner side of the mounting plate 303, respectively. Therefore, when the drive gear 302 rotates, it drives the two racks 304 to slide along the inner side of the mounting plate 303. Through the installation of the connecting rod 305, it drives the clamping plates 307 on both sides to move, thereby clamping or releasing the component. During the clamping process, by operating the fixing component 306, the sliding locking rod 3063 passes through the second U-shaped block 3062 and the locking rod 3063, and cooperates with the two first U-shaped blocks 3061 to stably fix the clamping plate 307 and the connecting rod 305, so that the clamping plate 307 remains stable during the processing and will not loosen. In addition, the installation of the fixing component 306 facilitates the quick replacement of different clamping plates 307.

[0041] Reference Figure 1 , Figure 3 and Figure 5The cleaning mechanism 2 includes a sliding ring 201, which is installed at the bottom of the machine body 1. A mounting block 203 is fixedly connected to the middle of the rear side of the sliding ring 201. A first motor 202 is installed on the top rear side of the sliding ring 201. A rotating short column 204 is fixedly connected to the output end of the first motor 202. A connecting rope 208 is fixedly connected to the left side of the rotating short column 204. A sliding block 207 is fixedly connected to the right side of the connecting rope 208. A fan 209 is installed on the top of the sliding block 207. An elastic rope 205 is fixedly connected to the right side of the sliding block 207. The left rear end of the elastic rope 205 is fixedly connected to the right side of the mounting block 203. An mounting component 206 is installed in the middle of the sliding ring 201. The mounting component 206 includes a moving wheel 2062, which is installed at the bottom of the sliding block 207. Multiple fixing blocks 2061 are fixedly connected at equal intervals around the middle of the sliding ring 201. The installation of the fixing blocks 2061 allows the sliding ring 201 to be securely installed.

[0042] Specifically, when the first motor 202 starts, the rotating short column 204 at its output end immediately begins to rotate, causing the connecting rope 208 to wind around. This allows the connecting rope 208 to drive the sliding block 207 to move within the sliding ring 201. One end of the elastic rope 205 on the right side of the sliding block 207 is connected to the mounting block 203. When the sliding block 207 moves, it stretches and contracts, working in conjunction with the connecting rope 208 to control the movement trajectory of the sliding block 207. The moving wheel 2062 at the bottom of the sliding block 207 rolls along the middle of the sliding ring 201, making the sliding smoother. The fixed block 2061 helps to limit the movement range of the moving wheel 2062, ensuring the stability of operation. The installation of the elastic rope 205 facilitates the reset of the fan 209. During the movement of the sliding block 207, the fan 209 on its top operates accordingly, using wind power to blow away and clean the debris generated during processing near the machine body 1.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A mounting rod 5 is installed on the top right side of the machine body 1, and a control device 6 is installed on the top of the mounting rod 5. A collection box 4 is fixedly connected to the bottom of the machine body 1, and the outer side of the collection box 4 is fixedly connected to the outer side of the fixing block 2061. A workbench 7 is installed at the front end of the machine body 1, and the top of the workbench 7 is slidably connected to the bottom of the clamping plate 307.

[0044] Specifically, the installation of control device 6 facilitates use by staff, the installation of workbench 7 facilitates the placement of processed parts, and the installation of collection box 4 facilitates the collection of most dirt.

[0045] Working principle: After the second motor 301 starts, the drive gear 302 at its output end rotates accordingly. Since the upper and lower ends of the drive gear 302 mesh with the racks 304 at the upper and lower ends of the inner side of the mounting plate 303 respectively, the rotation of the drive gear 302 will drive the two racks 304 to slide along the inner side of the mounting plate 303, and then drive the clamping plates 307 on both sides to move through the connecting rod 305 to achieve clamping or loosening of the part. During the clamping process, by operating the fixing component 306, the sliding locking rod 3063 is made to pass through the second U-shaped block 3062 and the locking rod 3063. With the cooperation of the two first U-shaped blocks 3061, the clamping plate 307 and the connecting rod 305 can be stably fixed to ensure that the part will not loosen during the processing. Moreover, the installation of the fixing component 306 facilitates the replacement of different clamping plates 307.

[0046] When the first motor 202 starts, the rotating short column 204 at its output end begins to rotate, causing the connecting rope 208 to wind around. This causes the connecting rope 208 to drive the sliding block 207 to move within the sliding ring 201. One end of the elastic rope 205 on the right side of the sliding block 207 is connected to the mounting block 203. As the sliding block 207 moves, it stretches and contracts, working with the connecting rope 208 to control the movement trajectory of the sliding block 207. The moving wheel 2062 at the bottom of the sliding block 207 rolls along the middle of the sliding ring 201, making the sliding smoother. The fixed block 2061 helps to limit the movement range of the moving wheel 2062, ensuring stable operation. The installation of the elastic rope 205 facilitates the reset of the fan 209. During the movement of the sliding block 207, the fan 209 at its top operates accordingly, using wind power to blow away and clean up the debris generated during processing near the machine body 1.

[0047] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
