Description

Technical Field

[0001] This utility model relates to the field of indexing chucks, specifically an adjustable indexing chuck. Background Technology

[0002] A chuck is a clamping device used in machining. It is usually installed on machine tools such as lathes and milling machines. The chuck body is used to install jaws and connect to the machine tool spindle. The jaws can be adjusted according to the shape and size of the workpiece to clamp the workpiece, thereby meeting different machining requirements.

[0003] An adjustable indexing chuck is a type of chuck whose size can be flexibly changed through an adjustment mechanism to adapt to the clamping requirements of workpieces of different diameters. It is widely used in various occasions that require clamping and indexing of round workpieces.

[0004] Existing indexing chucks typically clamp one end of the workpiece when holding it. When the workpiece is long, the upper part of the workpiece lacks support, resulting in instability when machining the upper part. Therefore, an adjustable indexing chuck is proposed to address the above problem. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An adjustable indexing chuck of this utility model includes a disc body; a groove is formed in the middle of the disc body; a pair of sliding seats are slidably connected to the bottom end of the groove; a pair of first fixed seats are fixedly connected to the top end of the sliding seats; a baffle is rotatably connected to the middle of the first fixed seats; a clamp is fixedly connected to the side wall of the baffle; the clamp is fixedly connected to one end of the baffle; a limiting seat is fixedly connected to the side wall of the baffle; the limiting seat is fixedly connected to the other end of the baffle; a screw is threadedly connected to the side wall of the disc body; the screw is connected to the side of the sliding seat. The wall; the screw is rotatably connected to the sliding seat; a pair of cleaning rings are fixed to the side wall of the disc; through the above structure, the cleaning rings can clean the contaminants on the surface of the screw when the screw rotates, adapting to different workpieces, and can adjust the clamping for workpieces of different models. The baffle and the first fixed seat rotate to cooperate, which can clamp the bottom end of the workpiece with the limiting seat and the middle position of the workpiece with the fixture, increasing the clamping area and reducing the instability of the workpiece caused by only clamping the bottom end of the workpiece while the middle of the workpiece has no support point, thus increasing the stability of the workpiece during clamping and processing and reducing its shaking.

[0007] Preferably, a pair of telescopic rods are hinged to the side wall of the sliding seat; a spring is sleeved on the outer wall of the telescopic rod; the top of the telescopic rod is hinged to the side wall of the baffle; through the telescopic characteristics of the telescopic rod, the position of the baffle near the limiting seat can be supported, increasing the stability of the baffle; the elasticity and telescopic characteristics of the spring itself can apply a pushing force to the baffle, causing the pair of baffles to move towards the center through the pushing force, clamping the workpiece in the center of the limiting seat more tightly, increasing the clamping force of the workpiece, and reducing workpiece loosening.

[0008] Preferably, a rubber wheel is rotatably connected to the side wall of the limiting seat; the rubber wheel is correspondingly arranged with the limiting seat; by rotating the rubber wheel, the direct contact between the workpiece and the limiting seat when the workpiece is inserted into the limiting seat can be reduced, which would cause friction between the workpiece and the limiting seat and damage to the workpiece surface. The rotatable connection between the rubber wheel and the limiting seat can reduce the direct contact between the workpiece and the limiting seat, increase the integrity of the workpiece surface, reduce workpiece scratches, and the rotation of the rubber wheel can also make it easier to remove the workpiece.

[0009] Preferably, a circular clamp is fixed to the side wall of the fixture; the circular clamp is correspondingly arranged with the fixture; by cooperating with the fixture, the middle position of the workpiece can be increased, the stability of the clamping can be improved, and the clamping surface of the workpiece can be larger when it is clamped, which can effectively reduce the shaking or displacement of the workpiece during the processing and increase the stability of the clamping.

[0010] Preferably, a second fixing seat is fixedly connected to the side wall of the screw; a ring is fixedly connected to the side wall of the second fixing seat; the ring can increase the convenience of the screw during rotation, making the screw more labor-saving to rotate and increasing the speed of the indexing plate adjustment.

[0011] Preferably, a rubber pad is fixed to the side wall of the fixture; the rubber pad is correspondingly arranged with the fixture; the rubber pad can reduce the contact between the workpiece and the fixture during clamping, thus reducing scratches on the workpiece surface. The elasticity of the rubber pad itself can also further buffer the clamping force during clamping, increase the friction of clamping, and make the clamping more stable.

[0012] The advantages of this utility model are:

[0013] 1. The adjustable indexing chuck of this utility model uses a cleaning ring to clean contaminants on the screw surface during screw rotation, reducing the entry of contaminants into the chuck body and preventing screw rotation jamming. Rotating the screw causes the sliding seat to slide along the groove, which can adapt to different workpieces and can adjust the clamping of workpieces of different models. The baffle and the first fixed seat rotate to clamp the bottom end of the workpiece with the limiting seat and the middle position of the workpiece with the clamp, increasing the clamping area and reducing the instability of the workpiece caused by only clamping the bottom end while the middle of the workpiece has no support point. This increases the stability of the workpiece during clamping and processing and reduces its shaking.

[0014] 2. The adjustable indexing chuck of this utility model can support the position of the baffle near the limiting seat through the telescopic characteristics of the telescopic rod, thereby increasing the stability of the baffle. The elasticity and telescopic characteristics of the spring itself can apply a pushing force to the baffle, so that a pair of baffles move towards the center through the pushing force, clamping the workpiece in the center of the limiting seat more tightly, increasing the clamping force of the workpiece and reducing the loosening of the workpiece.

[0022] 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 scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5As shown in the embodiment of this utility model, an adjustable indexing chuck includes a disc body 1; a groove 18 is formed in the middle of the disc body 1; a pair of sliding seats 11 are slidably connected to the bottom end of the groove 18; a pair of first fixed seats 12 are fixedly connected to the top end of the sliding seats 11; a baffle 13 is rotatably connected to the middle of the first fixed seats 12; a clamp 14 is fixedly connected to the side wall of the baffle 13; the clamp 14 is fixedly connected to one end of the baffle 13; a limiting seat 17 is fixedly connected to the side wall of the baffle 13; the limiting seat 17 is fixedly connected to the other end of the baffle 13. One end; a screw 15 is threadedly connected to the side wall of the disc body 1; the screw 15 is connected to the side wall of the sliding seat 11; the screw 15 and the sliding seat 11 are rotatably connected; a pair of cleaning rings 16 are fixedly connected to the side wall of the disc body 1; during operation, rotating the pair of screws 15 applies a thrust to the sliding seat 11, causing the sliding seat 11 to slide against the groove 18, moving the pair of sliding seats 11 towards the center for adjustment. For larger workpieces, rotating the screws 15 causes the sliding seats 11 to slide towards both sides of the groove 18, moving the workpiece from... After the clamp 14 is inserted and the limiting seat 17 contacts the workpiece, one end of the baffle 13 is rotatably connected to the first fixed seat 12. The baffle 13 moves to both sides near the limiting seat 17. When the limiting seat 17 at one end of the baffle 13 moves to both sides, the other end of the baffle 13 can move the clamp 14 to the center through the lever principle. Finally, the limiting seat 17 clamps the bottom end of the workpiece, and the clamp 14 clamps the middle position of the workpiece. The cleaning ring 16 can clean the contaminants on the surface of the screw 15 when the screw 15 rotates, reducing the amount of contaminants entering the disc. Inside body 1, the screw 15 is jammed during rotation. Rotating the screw 15 causes the sliding seat 11 to slide along the groove 18, which can adapt to different workpieces and can adjust the clamping for workpieces of different models. The baffle 13 and the first fixed seat 12 rotate to cooperate, which can clamp the bottom end of the workpiece with the limiting seat 17 and the middle position of the workpiece with the clamp 14, increasing the clamping area and reducing the instability of the workpiece caused by only clamping the bottom end of the workpiece and the lack of support point in the middle of the workpiece. This increases the stability of the workpiece during clamping and processing and reduces its shaking.

[0025] like Figures 1 to 2 As shown, a pair of telescopic rods 2 are hinged to the side wall of the sliding seat 11; a spring 21 is sleeved on the outer wall of the telescopic rod 2; the top of the telescopic rod 2 is hinged to the side wall of the baffle 13; during operation, when the bottom end of the workpiece is clamped in the limiting seat 17, the telescopic rod 2 and the spring 21 on the side of the sliding seat 11 can apply a pushing force to the baffle 13, further pressing the workpiece in the middle of the limiting seat 17. Through the telescopic characteristics of the telescopic rod 2, the position of the baffle 13 near the limiting seat 17 can be supported, increasing the stability of the baffle 13. The elasticity and telescopic characteristics of the spring 21 can apply a pushing force to the baffle 13, causing the pair of baffles 13 to move towards the middle through the pushing force, clamping the workpiece in the middle of the limiting seat 17 more tightly, increasing the clamping force of the workpiece, and reducing workpiece loosening.

[0026] like Figures 2 to 3 As shown, a rubber roller 3 is rotatably connected to the side wall of the limiting seat 17; the rubber roller 3 is correspondingly arranged with the limiting seat 17; during operation, when the workpiece contacts and is clamped by the limiting seat 17, it will first contact the rubber roller 3 on the side wall of the limiting seat 17. When the workpiece is inserted into the limiting seat 17, the rubber roller 3 rotates. After the workpiece is processed, it is taken out and rotated in contact with the rubber roller 3 to send the workpiece out. By rotating the rubber roller 3, the direct contact between the workpiece and the limiting seat 17 when the workpiece is inserted into the limiting seat 17 can be reduced, which causes friction between the workpiece and the limiting seat 17 and damages the surface of the workpiece. The rotatable connection between the rubber roller 3 and the limiting seat 17 can reduce the direct contact between the workpiece and the limiting seat 17, increase the integrity of the workpiece surface, and reduce workpiece scratches. The rotation of the rubber roller 3 can also make it easier to remove the workpiece.

[0027] like Figure 3 and Figure 5 As shown, a circular clamp 4 is fixedly connected to the side wall of the fixture 14; the circular clamp 4 is correspondingly arranged with the fixture 14; during operation, when the fixture 14 is clamping the middle section of the workpiece, the circular clamp 4 can further clamp the periphery of the workpiece, increasing the area of ​​the workpiece during clamping. The cooperation between the circular clamp 4 and the fixture 14 can increase the stability of the middle section of the workpiece clamping, making the clamping surface of the workpiece larger during clamping, which can effectively reduce the shaking or displacement of the workpiece during processing and increase the stability of clamping.

[0028] like Figure 4 As shown, a second fixed seat 5 is fixedly connected to the side wall of the screw 15; a ring 51 is fixedly connected to the side wall of the second fixed seat 5; during operation, the ring 51 can be directly held when rotating the screw 15, and a rotational force is applied to the ring 51 to drive the screw 15 to rotate. The ring 51 can increase the convenience of the screw 15 during rotation, making the screw 15 more effortless to rotate and increasing the speed of the indexing plate adjustment.

[0029] like Figure 5 As shown, a rubber pad 6 is fixed to the side wall of the clamp 14; the rubber pad 6 is correspondingly arranged with the clamp 14; during operation, the workpiece clamped in the middle of the clamp 14 comes into direct contact with the rubber pad 6 during clamping. The rubber pad 6 can reduce the contact between the workpiece and the clamp 14 during clamping, thus reducing scratches on the workpiece surface. The elasticity of the rubber pad 6 itself can also further buffer the clamping force during clamping, increase the friction of clamping, and make the clamp 14 clamp more stably.

[0030] Working principle: By rotating a pair of screws 15, the screws 15 apply a pushing force to the sliding seat 11, causing the sliding seat 11 to slide against the groove 18, moving the pair of sliding seats 11 towards the center for adjustment. For larger workpieces, rotating the screws 15 causes the sliding seats 11 to slide towards both sides of the groove 18, inserting the workpiece into the clamp 14. After the limiting seat 17 contacts the workpiece, one end of the baffle 13 is rotatably connected to the first fixed seat 12, and the end near the limiting seat 17 moves to both sides. When the limiting seat 17 at one end of the baffle 13 moves to both sides, the other end of the baffle 13 can move the clamp 14 towards the center through the lever principle. Finally, the limiting seat 17 clamps the bottom end of the workpiece, and the clamp 14 clamps the middle position of the workpiece. When the workpiece is held in the limiting seat 17, the telescopic rod 2 and spring 21 on the sliding seat 11 side can apply a pushing force to the baffle 13, further pressing the workpiece in the middle of the limiting seat 17. When the workpiece contacts and is clamped with the limiting seat 17, it will first contact the rubber wheel 3 on the side wall of the limiting seat 17. When the workpiece is inserted into the limiting seat 17, the rubber wheel 3 rotates. After the workpiece is processed, it is taken out and rotated in contact with the rubber wheel 3 to send the workpiece out. When the clamp 14 is clamping the middle section of the workpiece, the circular clamp 4 can further clamp the periphery of the workpiece, increasing the area of ​​the workpiece when clamped. When the screw 15 is rotated, the ring 51 can be directly gripped, and the rotational force is applied to the ring 51 to drive the screw 15 to rotate. The workpiece clamped in the middle of the clamp 14 is in direct contact with the rubber pad 6 when clamped.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
