Description

Technical Field

[0001] The utility model relates to the technical field of graphite fixtures, in particular to an automatic positioning graphite fixture. Background Art

[0002] The fixture is one of the most common devices in the prior art. When clamping shaft workpieces, such as the Chinese patent application number 202122748964.2, an automatic positioning graphite tooling fixture is used.

[0003] When in use, the shaft workpiece is fixed by the wrapping assembly 10 through the flexible chain 110, which increases the contact area, effectively reduces the deformation of the tooling and the parts caused by the contact and extrusion between the tooling and the parts, improves reliability, and can adapt to shaft parts of different diameters to improve versatility; however, the fixing effect of the whole process is limited, there is no fixation in the upper direction of the shaft part, and the workpiece is only held by the flexible chain 110. In this way, the fixing effect is poor and the shaft body is easy to shake. Therefore, an automatic positioning graphite tooling fixture is needed to improve this problem. Utility Model Content

[0007] Preferably, a spring is sleeved on the outer surface of the telescopic rod, and the spring can automatically push the telescopic rod to extend and reset, so that the arc-shaped clamping block can be clamped into the clamping slot.

[0008] Preferably, an extrusion screw is provided on one side of the slot surface through a threaded engagement, and the extrusion screw can be inserted into the limit slot to lock the insert block, so that the graphite sheet cannot be detached.

[0010] Preferably, a twisting block is fixedly provided at one end of the screw rod, and the screw rod can be conveniently rotated by the twisting block; the movable ring is driven to move left and right along the screw rod through the screw rod and the thread.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When clamping, the utility model rotates the screw through the bearing, so that the screw and the thread drive the movable ring to move left and right along the screw; when the movable ring moves, the sliders can be driven to approach or open each other through the transmission rod, so that the graphite sheets can be driven to clamp shafts of different diameters; thus, the device has a good use effect, can conveniently position and clamp shafts of various diameters, and is highly stable during clamping, and the shaft is not easy to shake.

[0013] 2. When the utility model is used, if a high-temperature shaft is clamped, in order to prevent the shaft from deforming and limit the clamping force, when the screw is turned to tighten the graphite sheets closer to each other, they are clamped on the surface of the shaft. If the screw is turned too tightly, the arc-shaped clamping block will be squeezed to a greater extent, thereby causing the telescopic rod to shrink, so that the arc-shaped clamping block cannot be engaged in the slot, and the arc-shaped clamping block will be detached from the slot. At this time, the graphite sheet will fall off the surface of the slider, thereby preventing the shaft from being damaged by excessive clamping force. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides a technical solution: an automatic positioning graphite tooling fixture, comprising a first connecting plate 1, a second connecting plate 2 is arranged on one side of the first connecting plate 1, a clamping mechanism for clamping a shaft body is arranged between the first connecting plate 1 and the second connecting plate 2, the clamping mechanism comprises a screw 3, a movable ring 4, a slide groove 5, a slider 6, and a transmission rod 7, a screw 3 is movably arranged between the first connecting plate 1 and the second connecting plate 2 through a bearing, a movable ring 4 is movably screwed on the outer surface of the screw 3 through a thread, a slide groove 5 is provided on the outer surface of the second connecting plate 2, a slider 6 is movably engaged inside the slide groove 5, a transmission rod 7 is movably arranged on the outer surface of the movable ring 4 through a pin shaft, and one end of the transmission rod 7 close to the slider 6 is movably connected to the slider 6 through a rotating shaft, and a graphite sheet 8 is arranged on the outer surface of the slider 6.

[0020] A snap-fit ​​mechanism is provided between the graphite sheet 8 and the slider 6, and the snap-fit ​​mechanism includes a slot 9, an insert block 10, a telescopic rod 11, an arc-shaped block 12, and a slot 13. The outer surface of the slider 6 is provided with a slot 9, the outer surface of the graphite sheet 8 is fixedly provided with an insert block 10, the inner side of the slider 6 is fixedly provided with a telescopic rod 11, the movable end of the telescopic rod 11 is fixedly provided with an arc-shaped block 12, the outer surface of the insert block 10 is provided with an arc-shaped block 12, and the arc-shaped block 12 is movably engaged with the outer surface of the insert block 10. The inside of the card slot 13; the graphite sheet 8 and the slider 6 can be conveniently fixed by the card mechanism, and the fixing method of the card mechanism can limit the force of the graphite sheet 8 when clamping the shaft body. When the screw 3 is turned to make the graphite sheets 8 close to each other and tighten, they are clamped on the surface of the shaft body. If the screw is turned too tight, the arc-shaped card block 12 will not be able to be clamped in the card slot 13, so that the arc-shaped card block 12 will be separated from the card slot 13, and the graphite sheet 8 will fall off from the surface of the slider 6, so that the clamping force is too large to damage the shaft body;

[0021] The outer surface of the telescopic rod 11 is sleeved with a spring 14, which can automatically push the telescopic rod 11 to extend and reset, so that the arc-shaped clamping block 12 can be clamped into the clamping slot 13;

[0022] A squeeze screw 15 is provided on one side of the surface of the slot 9 through a threaded engagement, and the squeeze screw 15 can be inserted into the limit groove 16 to lock the insert block 10, so that the graphite sheet 8 cannot be separated. In this way, when facing the clamping of some shafts that need to be rigidly locked, the device can still be competent;

[0023] A limiting groove 16 is provided on one side of the surface of the plug block 10, and the limiting groove 16 can limit and lock the plug block 10 and the graphite sheet 8;

[0025] Working principle: When using this device, the device uses graphite sheets 8 to clamp and fix the shaft body. The graphite sheets 8 can withstand high temperatures to facilitate clamping of high-temperature shaft bodies. When clamping, the screw 3 is rotated through the bearing, so that the movable ring 4 is driven by the screw 3 and the thread to move left and right along the screw 3; when the movable ring 4 moves, the sliders 6 can be driven to approach or open each other through the transmission rod 7, so that the graphite sheets 8 can be driven to clamp shaft bodies of different diameters; in this way, the device has a good use effect, can conveniently position and clamp shaft bodies of various diameters, and is highly stable during clamping, and the shaft body is not easy to shake;

[0026] Furthermore, when the device is used, if a high-temperature shaft is clamped, in order to prevent the shaft from being deformed and limit the clamping force, when the screw 3 is turned to make the graphite sheets 8 close to each other and tighten, they are clamped on the surface of the shaft. If the screw is turned too tight, the arc block 12 will be greatly squeezed, so that the telescopic rod 11 will shrink, so that the arc block 12 cannot be clamped in the slot 13, so that the arc block 12 will be separated from the slot 13, and the graphite sheet 8 will fall off the surface of the slider 6, so that the clamping force is too large to damage the shaft;

[0027] When the device is used, the screw 15 can be inserted into the limiting groove 16 by squeezing, so that the insert block 10 is locked, so that the graphite sheet 8 cannot be separated. In this way, when facing the clamping of some shafts that need to be rigidly locked, the device can still perform the task.
