Technical Field

[0001] The utility model relates to the technical field of elastic collet chuck handles, in particular to an elastic collet chuck handle. Background Art

[0002] The tool holder is a fixed connection part used to be installed on the milling cutter, which makes it easy for the milling cutter to fit the elastic collet on the milling machine and install it.

[0003] When the tool handle body is installed on the milling cutter for use, the milling cutter is first screwed into the inside of one end of the tool handle body, and then the other end is clamped into the inside of the elastic collet body on the milling machine for fixation. Since the tool handle body and the elastic collet body are fixed by the friction between the extrusion of the elastic collet body and the contact position, they are prone to loosening during use, resulting in unstable fixation, causing the milling cutter to tilt during processing, affecting the processing effect and causing damage to the product. Utility Model Content

[0004] The utility model proposes an elastic collet chuck to solve the problem that the fixation between the tool handle body and the elastic collet body is fixed by the friction between the extrusion of the elastic collet body and the contact position, which is easy to loosen during use, resulting in unstable fixation, causing the milling cutter to tilt during processing, affecting the processing effect and causing damage to the product.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an elastic collet chuck handle, comprising a chuck body and an elastic collet body, the inner wall of one end of the elastic collet body being detachably connected to the outer surface of one end of the chuck body, a limiting device being symmetrically arranged on the outer surface of one end of the chuck body, an anti-slip device being arranged on the outer surface of one end of the chuck body, the limiting device comprising a bracket, the inner wall of the bracket being rotatably connected to a threaded rod, the outer surface of the chuck body being symmetrically provided with thread grooves, the inner wall of the thread groove being threadedly connected to the outer surface of the threaded rod, one end of the bracket being fixedly connected to a limiting arc block, and one side of the limiting arc block abutting against one side of the elastic collet body.

[0006] The effect achieved by the above-mentioned components is: by setting a limit device, when the shank body is installed on the milling cutter for use, the milling cutter is first screwed into the inside of one end of the shank body, and then the other end is clamped into the inside of the elastic collet body on the milling machine. After the threaded rod is screwed to a certain position in the threaded groove by a tool, the other hand holds the bracket so that it does not rotate with the rotation of the threaded rod, but only moves in one direction. When the threaded rod drives the bracket to move to a certain position, the limit arc block on one end of the bracket is abutted against one side of the elastic collet body to clamp it, so that the connection between the shank body and the elastic collet body can be fixed for a second time, making the connection more secure and less likely to loosen, so that when the milling cutter is used for processing in the later stage, it is not easy to tilt, which will affect the processing effect. The processing efficiency of the product is improved and the number of defective products is reduced.

[0007] Preferably, a plurality of anti-sliding blocks are fixedly connected to one side of the limiting arc block, and the anti-sliding blocks are made of rubber material.

[0008] The effect achieved by the above components is that by providing the anti-sliding block, the contact friction force on one side of the anti-sliding block can be increased, so that when the anti-sliding block abuts against one side of the elastic collet body, the abutment is more firm and less likely to shake.

[0009] Preferably, a round rod is fixedly connected to one side of the bracket, and round holes are symmetrically opened on the outer surface of the handle body, and the inner wall of the round hole is slidably connected to the outer surface of the round rod.

[0010] The effect achieved by the above components is that by providing the round rod and the round hole, the movement direction of the bracket can be limited and fixed, so that it is not easy to rotate with the rotation of the threaded rod.

[0011] Preferably, a screw groove is formed on one side of the threaded rod, and a longitudinal section of the screw groove is hexagonal.

[0012] The effect achieved by the above components is that by providing the screw groove, when it is inconvenient to screw the threaded rod manually, a screwing tool of a corresponding shape can be inserted into the screw groove and screwed, thereby making it convenient to screw the threaded rod.

[0013] Preferably, the anti-slip device includes a rubber block, the outer surface of the handle body is symmetrically fixedly connected to the limiting block, the inner wall of the rubber block is symmetrically provided with limiting grooves, the size and shape of the inner wall of the limiting groove are adapted to the size and shape of the outer surface of the limiting block, and the size and shape of the inner wall of the rubber block are adapted to the size and shape of the outer surface of one end of the handle body.

[0014] The effect achieved by the above-mentioned components is: by setting the anti-slip device, when using the tool handle body, first put the rubber block on the outer surface of one end of the tool handle body, and make its limit block stuck in the limit groove for limiting, so that the rubber block is not easy to rotate after being put on the outer surface of one end of the tool handle body. The rubber block can increase the contact friction force of the outer surface of one end of the tool handle body, making it more firm and not easy to fall off when it is manually held, thereby avoiding the situation where the milling cutter falls off when installed on the tool handle body and causes damage to the milling cutter, and at the same time, it is convenient to grasp the tool handle body and then install it on the elastic collet body.

[0015] Preferably, the cross section of the limiting block is in a T-shape, and the cross section of the limiting groove is in a T-shape.

[0016] The effect achieved by the above components is: by setting the limit block and the limit groove in a T shape, the internal limit hook of the rubber block can be hooked, making it less likely to deform and expand outward, and the inner wall is more closely fitted to the outer surface of the handle body.

[0017] Preferably, a plurality of magnet blocks are fixedly connected to one side of the rubber block, an iron ring block is fixedly connected to the outer surface of the handle body, and one side of the magnet block is magnetically attracted to one side of the iron ring block.

[0018] The effect achieved by the above components is: by setting the iron ring block and the magnet block, after the rubber block is sleeved and clamped on the outer surface of one end of the handle body to a certain position, several magnet blocks on one side will be adsorbed and fixed on one side of the iron ring block, making its sleeve connection more firm and stable.

[0019] Preferably, a plurality of anti-skid protrusions are fixedly connected to the outer surface of the rubber block, and the plurality of anti-skid protrusions are arranged at equal distances.

[0020] The effect achieved by the above components is that by arranging the anti-skid protrusions, the roughness of the outer surface of the rubber block can be increased, making it less likely to slide when it is manually held, and the grip is more secure.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by arranging a limiting device, when the tool handle body is installed on the milling cutter for use, the milling cutter is firstly screwed into the interior of one end of the tool handle body, and then the other end thereof is clamped into the interior of the elastic collet body on the milling machine; after the threaded rod is screwed to a certain position in the thread groove by a tool, the other hand holds the bracket so that it does not rotate with the rotation of the threaded rod, but only moves in the direction of one side; when the threaded rod drives the bracket to move to a certain position, the limiting arc block on one end thereof abuts against one side of the elastic collet body to clamp and fix it, thereby the connection between the tool handle body and the elastic collet body can be fixed for a second time, making the connection more firm and less prone to loosening, thereby preventing the occurrence of tilting that affects the processing effect when the milling cutter is used for processing in the later stage, thereby improving the product processing efficiency and reducing the number of defective products.

When the shank body 1 is installed on the milling cutter for use, the milling cutter is first screwed into the inside of one end of the shank body 1, and then the other end is clamped into the inside of the elastic collet body 4 on the milling machine. After the threaded rod 23 is screwed to a certain position in the threaded groove 21 by a tool, the other hand holds the bracket 22 so that it does not rotate with the rotation of the threaded rod 23, but only moves in one direction. When the threaded rod 23 drives the bracket 22 to move to a certain position, the limiting arc block 24 on one end of the bracket is abutted against one side of the elastic collet body 4 to clamp it, so that the connection between the shank body 1 and the elastic collet body 4 can be fixed for a second time, making the connection more secure and less prone to loosening, so that when the milling cutter is used for processing in the later stage, it is not easy to tilt, which will affect the processing effect, thereby improving product processing efficiency and reducing the number of defective products.

[0029] Reference Figure 2 and Figure 3 As shown, this embodiment discloses that one side of the limiting arc block 24 is fixedly connected with a plurality of anti-sliding blocks 25, and the anti-sliding blocks 25 are made of rubber. By providing the anti-sliding blocks 25, the contact friction force on one side of the anti-sliding blocks 25 can be increased, so that when the anti-sliding blocks 25 abut against one side of the elastic collet body 4, the abutment is more firm and less likely to shake. A round rod 26 is fixedly connected to one side of the bracket 22, and a round hole 27 is symmetrically provided on the outer surface of the handle body 1, and the inner wall of the round hole 27 is slidably connected to the outer surface of the round rod 26. By providing the round rod 26 and the round hole 27, the movement direction of the bracket 22 can be limited and fixed, so that it is not easy to rotate with the rotation of the threaded rod 23.

[0030] Reference Figure 2 and Figure 3 As shown, this embodiment discloses that a screw groove 28 is provided on one side of the threaded rod 23, and the longitudinal section of the screw groove 28 is hexagonal. By providing the screw groove 28, when it is inconvenient to manually screw the threaded rod 23, a screwing tool of a corresponding shape can be inserted into the screw groove 28 and screwed, so that the threaded rod 23 can be screwed conveniently.

[0031] Reference Figure 4As shown, the present embodiment discloses that the anti-slip device 3 includes a rubber block 32, the outer surface of the handle body 1 is symmetrically fixedly connected with the limiting block 31, the inner wall of the rubber block 32 is symmetrically provided with a limiting groove 33, the inner wall size and shape of the limiting groove 33 are adapted to the outer surface size and shape of the limiting block 31, and the inner wall size and shape of the rubber block 32 are adapted to the outer surface size and shape of one end of the handle body 1. When the handle body 1 is used, the rubber block 32 is first sleeved on the outer surface of one end of the handle body 1, and the limiting block 31 is clamped in the limiting groove 33 for limiting, so that the rubber block 32 is not easy to rotate after being sleeved on the outer surface of one end of the handle body 1, and the rubber block 32 can increase the contact friction force of the outer surface of one end of the handle body 1, so that it is more firm and not easy to fall off when it is manually held, thereby avoiding the situation that the milling cutter is damaged by falling off when it is installed on the handle body 1, and at the same time, it is convenient to grasp the handle body 1 and then install it on the elastic collet body 4.

[0032] Reference Figure 4 As shown, the embodiment discloses that the cross section of the limit block 31 is in a T-shape, and the cross section of the limit groove 33 is in a T-shape. By setting the limit block 31 and the limit groove 33 in a T-shape, the internal limit of the rubber block 32 can be hooked, so that it is not easy to deform and expand outward, and the inner wall is more closely fitted with the outer surface of the handle body 1. One side of the rubber block 32 is fixedly connected with a plurality of magnet blocks 34, and the outer surface of the handle body 1 is fixedly connected with an iron ring block 35, and one side of the magnet block 34 is magnetically attracted to one side of the iron ring block 35. By setting the iron ring block 35 and the magnet block 34, after the rubber block 32 is sleeved and stuck on the outer surface of one end of the handle body 1 to a certain position, the plurality of magnet blocks 34 on one side will be adsorbed and fixed on one side of the iron ring block 35, so that the sleeve connection is more firm and stable. The outer surface of the rubber block 32 is fixedly connected with a plurality of anti-skid protrusions 36, and the plurality of anti-skid protrusions 36 are arranged at equal distances.

[0033] Working principle: when the shank body 1 is installed on the milling cutter for use, the milling cutter is first screwed into the inside of one end of the shank body 1, and then the other end is clamped into the inside of the elastic collet body 4 on the milling machine. By inserting the tool in the screw groove 28 and screwing it, the threaded rod 23 can be driven to screw to a certain position in the threaded groove 21. Then, under the limiting action of the round rod 26 and the round hole 27, the threaded rod 23 drives the bracket 22 to move to one side to a certain position, so that the limiting arc block 24 and the anti-sliding block 25 on one end of the shank body 1 abut against one side of the elastic collet body 4 to clamp and fix it, so that the connection between the shank body 1 and the elastic collet body 4 can be fixed for the second time, making the connection more firm and less prone to loosening, so that when the milling cutter is used for processing in the later stage, it is not easy to tilt, which will affect the processing effect. The problem improves the product processing efficiency and reduces the number of defective products.

[0034] When using the shank body 1, hold the anti-skid protrusion 36 and the rubber block 32 to sleeve their inner walls on the outer surface of one end of the shank body 1, and make the limit block 31 stuck in the limit groove 33 for limiting. After being sleeved to a certain position, several magnet blocks 34 on one side will be adsorbed on one side of the iron ring block 35, so that the rubber block 32 is not easy to rotate after being sleeved on the outer surface of one end of the shank body 1. The rubber block 32 can increase the contact friction force of the outer surface of one end of the shank body 1, making it more firm and less likely to fall off when it is manually held, thereby avoiding the situation where the milling cutter falls off when installed on the shank body 1 and causes damage to the milling cutter, and at the same time, it is convenient to grasp the shank body 1 and install it on the elastic collet body 4.
