[0002] A milling machine fixture is a device used to clamp workpieces on a milling machine. Its main function is to fix the workpiece on the milling machine for processing. The milling machine fixture mainly consists of a fixture body, a fixture base, a fixture steel sleeve, a fixture pressing plate, etc., and achieves the purpose of clamping the workpiece through fastening bolts or handwheels.

[0003] There are various classifications of milling machine fixtures. The most common one is the linear feed fixture, which has advantages such as high efficiency, stability, and versatility. However, the height of the clamping plate of the existing device is fixed and cannot be adjusted. When fixing a relatively high workpiece, only the lower end of the workpiece can be clamped, while the upper end of the workpiece is not fixed. The workpiece may shake left and right during processing, so the overall stability of the device is poor. Therefore, a milling machine fixture with high clamping stability is proposed to solve the above problems. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figure 1 - Figure 3 As shown in the figure, an embodiment provided by the present invention: A milling machine fixture with high clamping stability, including a base 1 for supporting the clamping plate 2. The top end of the base 1 is slidably connected with a clamping plate 2 for clamping a workpiece. The top end of the clamping plate 2 is provided with a moving component 4 for adjusting the height of the clamping plate 2. The moving component 4 includes a support column 41 for supporting the fixed plate 3. The top end of the support column 41 is fixedly connected with a fixed plate 3 for assisting in clamping. The inner wall of the base 1 is provided with a rotating component 7 for driving the moving component 4. The inner wall of the base 1 slides with a storage box 5 for collecting debris generated by the workpiece. The inner wall of the base 1 is provided with a groove adapted to the storage box 5 for accommodating the storage box 5. The front end of the storage box 5 is fixedly connected with a handle 6 for pulling the storage box 5. The top end of the storage box 5 is fixedly connected with a rubber block 10 for fixing the storage box 5. The top end of the base 1 is provided with a through slot 8 for allowing the debris generated by the workpiece to fall into the storage box 5. The front end of the base 1 is slidably connected with a limit block 9 for supporting the cross bar 48. The rotating component 7 includes a threaded rod 71 for supporting the movement of the slide block 73. The threaded rod 71 is installed on the inner wall of the base 1. The threaded rod 71 is a double-headed threaded rod with opposite thread directions at both ends. By rotating the knob 72, the two clamping plates 2 will move inward simultaneously. The right end of the threaded rod 71 is installed with a knob 72 for rotating the threaded rod 71. The bottom end of the clamping plate 2 is fixedly connected with a slide block 73 for driving the clamping plate 2 to move. The slide block 73 slides on the inner wall of the base 1. The slide block 73 is threadedly connected to the outer wall of the threaded rod 71. Rotating the knob 72 can drive the slide block 73 to slide on the inner wall of the base 1, thereby driving the clamping plate 2 to slide inward to clamp the workpiece.

[0024] Refer to Figure 1 、 Figure 3 、 Figure 4The support column 41 is slidably connected to the inner wall of the splint 2. The support column 41 is provided with two groups, which are arranged with the center line of the base 1 as the symmetric axis. The bottom end of the fixed plate 3 is fixedly connected with a sliding tube 42 for adjusting the height of the fixed plate 3. The sliding tube 42 is slidably connected to the inner wall of the splint 2. The sliding tube 42 is provided with two groups, which are arranged with the center line of the base 1 as the symmetric axis. The inner wall of the splint 2 is slidably connected with a fixing block 44 for fixing the sliding tube 42. The front end of the fixing block 44 is fixedly connected with a spring 45 for pushing the fixing block 44. The front end of the spring 45 is fixedly connected to the inner wall of the splint 2. The spring 45 will always push the fixing block 44 to be clamped in the groove 43. The outer wall of the sliding tube 42 is provided with a fixing block 44 for fixing the sliding tube 42. There is a groove 43 for accommodating a fixing block 44, and the groove 43 is adapted to the fixing block 44. When the fixing block 44 is clamped in the groove 43, the sliding tube 42 will be fixed and unable to move. The left end of the fixing block 44 is fixedly connected to a shifting block 47 for driving the fixing block 44 to disengage from the groove 43. The bottom end of the shifting block 47 is fixedly connected to an L rod 46 for driving the shifting block 47 to slide. The front end of the L rod 46 is slidably connected to a cross bar 48 for supporting the sliding of the L rod 46. The bottom end of the cross bar 48 is fixedly connected to the top of the limit block 9. When the splint 2 drives the L rod 46 to move inward, the L rod 46 will push the cross bar 48 to move forward, and the cross bar 48 will drive the limit block 9 to slide forward.

[0025] Working principle: When fixing a higher workpiece, the operator first moves the shift block 47, which will drive the fixing block 44 to disengage from the groove 43. At this time, the slide tube 42 will be released, and then the fixing plate 3 is pulled to drive the support column 41 and the slide tube 42 to move upward until the height of the workpiece is reached. Then the shift block 47 is released, and the fixing block 44 will slide into the groove 43 due to the reverse force of the spring 45. Then the knob 72 is turned to drive the clamping plate 2 to move inward until the object is completely fixed. Since it is fixed from both high and low places at the same time, the fixing effect is better.

[0026] When cleaning the debris, the operator first turns the knob 72 to move the splint 2 outward until the splint 2 returns to the initial position, then takes out the workpiece, and then the operator sweeps the debris generated by drilling and milling of the workpiece into the through groove 8, and the debris will enter the storage box 5 through the through groove 8. After cleaning, pull the handle 6 to slide the storage box 5 forward until the storage box 5 is completely separated from the base 1, and then process the debris to complete the cleaning of the entire device.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
