Description

Technical Field

[0001] This utility model relates to the field of cutting tool manufacturing technology, and in particular to adjustable fixtures for cutting tool manufacturing. Background Technology

[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. Fixtures are devices used to hold workpieces or cutting tools during the tool manufacturing process; their structure can be adjusted to accommodate workpieces of different sizes, shapes, or processing requirements.

[0003] In existing technologies, general fixtures typically employ a clamping block structure with an arc-shaped jaw when positioning cutting tools. This type of clamping block with an arc-shaped jaw has good adaptability to cutting tools with small dimensional variations and can achieve stable clamping within a certain tolerance range. However, when the size of the cutting tool varies significantly, the size of the arc-shaped jaw cannot be matched with the cutting tool, which leads to a reduction in the effective contact area between the clamping block and the cutting tool. A reduced contact area results in insufficient clamping friction, which not only makes the clamping less secure but may even cause clamping marks on the cutting edge. Therefore, it is necessary to improve the tool manufacturing by developing an adjustable fixture to solve the above problems. Utility Model Content

[0004] To overcome the problem of unstable positioning caused by insufficient friction due to small contact area between the clamping block and the tool when dealing with tools with large dimensional changes.

[0005] The technical solution of this utility model is as follows: an adjustable tool manufacturing fixture, including a first mounting plate, a second mounting plate fixedly connected to the first mounting plate, a limiting cylinder fixedly connected to the second mounting plate, a first sliding plate slidably connected to the limiting cylinder, a first clamping plate fixedly connected to the first sliding plate, a second sliding plate slidably connected to the limiting cylinder, a second clamping plate fixedly connected to the second sliding plate, a guide assembly disposed on the limiting cylinder, and a power assembly mounted on the first mounting plate. The power assembly drives the first sliding plate and the second sliding plate to slide synchronously through the guide assembly, thereby clamping and positioning the tool through the first clamping plate and the second clamping plate.

[0006] Preferably, there are several first and second sliding plates, and these first and second sliding plates are evenly arranged in a circular array on the limiting cylinder.

[0007] Preferably, the first clamping plate is provided with a protrusion, and the second clamping plate is provided with a groove that matches the protrusion. When the first clamping plate and the second clamping plate are close together, the protrusion enters the groove.

[0008] Preferably, the guide assembly includes a first guide rod fixedly connected to the first slide plate, a second guide rod fixedly connected to the second slide plate, a guide disc rotatably connected to the limiting cylinder, a gear fixedly connected to the guide disc, and a gear plate meshing with the gear. The rotation of the guide disc drives several first guide rods and second guide rods to move synchronously.

[0009] Preferably, the guide plate has matching guide grooves at corresponding positions of the first guide rod and the second guide rod, and the first guide rod and the second guide rod are disposed inside the guide grooves.

[0010] Preferably, the power assembly includes a limiting frame fixedly connected to the first mounting plate, a positioning frame fixedly connected to the limiting frame, a hydraulic telescopic rod fixedly connected to the positioning frame, a connecting plate fixedly connected to one end of the hydraulic telescopic rod, and the connecting plate fixedly connected to the bottom of the toothed plate.

[0011] Preferably, the toothed plate has a matching groove at the corresponding position of the limiting frame, and the toothed plate slides on the limiting frame through the groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. By having multiple first clamping plates and second clamping plates simultaneously contact the tool, the contact area between the clamping plates and the tool is guaranteed. The staggered design of the protrusions and grooves allows for a larger range of movement of the first clamping plates and second clamping plates, resulting in more dimensions that can be positioned, a wider range of applications, flexible use, and improved tool stability.

[0014] 2. The rotation of the guide plate synchronously drives the sliding adjustment of several first and second slide plates, eliminating the need for multiple power sources, saving manufacturing costs, simplifying operation, and improving work efficiency. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of an adjustable tool production fixture, including a first mounting plate 1, a second mounting plate 21 fixedly connected to the first mounting plate 1, a limiting cylinder 22 fixedly connected to the second mounting plate 21, a first sliding plate 23 slidably connected to the limiting cylinder 22, a first clamping plate 24 fixedly connected to the first sliding plate 23, a second sliding plate 25 slidably connected to the limiting cylinder 22, a second clamping plate 26 fixedly connected to the second sliding plate 25, a guide assembly disposed on the limiting cylinder 22, and a power assembly mounted on the first mounting plate 1. The power assembly drives the tool through the guide assembly. The first slide plate 23 and the second slide plate 25 slide synchronously, so that the first slide plate 23 and the second slide plate 25 clamp the positioning tool through the first clamping plate 24 and the second clamping plate 26. The power component pushes the first slide plate 23 and the second slide plate 25 synchronously through the guide component. The first slide plate 23 and the second slide plate 25 slide synchronously, so that the first clamping plate 24 and the second clamping plate 26 contact the tool at the same time. The sliding distance of the first slide plate 23 and the second slide plate 25 can be adjusted according to the size of the tool. It can be applied to tools with large size variations. Moreover, the first clamping plate 24 and the second clamping plate 26 can be disassembled and adjusted in time according to actual use.

[0023] Please see Figures 1-3 In this embodiment, a plurality of first sliding plates 23 and second sliding plates 25 are provided, and the plurality of first sliding plates 23 and second sliding plates 25 are evenly arranged in a circular array on the limiting cylinder 22. The circular array design allows the tool to be clamped at the center position of the limiting cylinder 22, that is, in the central position, so that frequent centering operations are not required during processing, thereby improving processing accuracy and processing efficiency. The first clamping plate 24 is provided with a protrusion, and the second clamping plate 26 is provided with a groove adapted to the protrusion. When the first clamping plate 24 and the second clamping plate 26 are close together, the protrusion enters the groove. The protrusion and the groove are positioned in a corresponding and staggered manner, which can avoid path conflict between the first clamping plate 24 and the second clamping plate 26, and increase the moving distance of the first clamping plate 24 and the second clamping plate 26, thereby being applicable to tools of more sizes.

[0024] Please see Figure 1 , Figure 4In this embodiment, the guiding assembly includes a first guide rod 27 fixedly connected to the first slide plate 23, a second guide rod 28 fixedly connected to the second slide plate 25, a guide disc 31 rotatably connected to the limiting cylinder 22, a gear 32 fixedly connected to the guide disc 31, and a toothed plate 33 meshing with the gear 32. The rotation of the guide disc 31 drives several first guide rods 27 and second guide rods 28 to move synchronously. Several first slide plates 23 and second slide plates 25 can slide synchronously through one guide disc 31, eliminating the need for multiple power sources and saving costs. The guide disc 31 has matching guide grooves at corresponding positions of the first guide rods 27 and second guide rods 28, and the first guide rods 27 and second guide rods 28 are located inside the guide grooves. The guide grooves allow the guide disc 31 to push the first guide rods 27 and second guide rods 28 when rotating, thereby achieving the effect of synchronous movement of several first guide rods 27 and second guide rods 28.

[0025] Please see Figure 1 , Figure 4 , Figure 5 In this embodiment, the power assembly includes a limiting frame 41 fixedly connected to the first mounting plate 1, a positioning frame 42 fixedly connected to the limiting frame 41, a hydraulic telescopic rod 43 fixedly connected to the positioning frame 42, and a connecting plate 44 fixedly connected to one end of the hydraulic telescopic rod 43. The connecting plate 44 is fixedly connected to the bottom of the toothed plate 33. The hydraulic telescopic rod 43 pushes the toothed plate 33, thereby driving the gear 32 and the guide plate 31 to rotate. The hydraulic telescopic rod 43 provides more stable clamping power. The toothed plate 33 has a matching groove at the corresponding position of the limiting frame 41, and the toothed plate 33 slides on the limiting frame 41 through the groove. The groove makes the sliding of the toothed plate 33 more stable and smooth, avoids the toothed plate 33 from jamming, and ensures the stable operation of the device.

[0026] During operation, the first mounting plate 1 can be fixed in position with bolts, and the second mounting plate 21 can be fixed on the first mounting plate 1 with bolts. The tool to be processed is placed in the axial position inside the limiting cylinder 22. The hydraulic telescopic rod 43 pushes the connecting plate 44, the connecting plate 44 drives the toothed plate 33, the toothed plate 33 slides and drives the meshing gear 32 to rotate, the gear 32 drives the guide plate 31, the guide plate 31 pushes the first guide rod 27 and the second guide rod 28 through the guide groove, thereby pushing the first slide plate 23 and the second slide plate 25 through the first guide rod 27 and the second guide rod 28. The first slide plate 23 and the second slide plate 25 clamp the tool through the first clamping plate 24 and the second clamping plate 26, so that the tool is positioned in the axial position of the limiting cylinder 22.

[0027] Through the above steps, multiple first clamping plates 24 and second clamping plates 26 simultaneously contact the tool, thereby ensuring the contact area between the clamping blocks and the tool. This solves the problem of unstable positioning caused by insufficient friction due to the small contact area between the clamping blocks and the tool when dealing with tools with large size variations.
