The tool is an annular cylinder, and the annular cylinder is divided into a first section, a second section and a connecting section. The first section and the second section are fixedly connected through the connecting section; the outer diameter of the first section is equal to the diameter of the chuck inner thread; the outer diameter of the second section is equal to that of the chuck shaft; the outer diameter of the connecting section is equal to that of the second section; and the second section is provided with an opening and a groove. Based on the device convenient for replacing the tensioning block of the chuck, when the tensioning block on the TMT winding head is aged and needs to be replaced, the first section of the tool is clamped into the internal thread of the chuck, the tensioning module on the outer side of the tensioning block needing to be replaced is withdrawn and arranged on the second section of the tool in a sleeving manner, and when the aged tensioning block is replaced, the tensioning block on the outer side of the tensioning block needing to be replaced is replaced. And then the retreated tensioning module is pushed back, so that the time for disassembling and assembling the tensioning module on the outer side is saved, and the working efficiency is greatly improved.

Description

Technical Field

[0001] The utility model relates to the technical field of chuck tension block replacement tools, in particular to a device for facilitating replacement of a chuck tension block. Background Art

[0002] The TMT winding head's chuck shaft is equipped with a tensioning block to hold the paper tube in place. However, this tensioning block is made of nylon and, after prolonged operation on the machine, will wear, crack, and age, causing the paper tube to become insecure and impacting production. Therefore, when the tensioning block ages, it must be promptly removed and replaced. However, a TMT winding head has two chucks, each with 102 tensioning blocks. While it's relatively easy to remove and replace the aging tensioning blocks on the outer edges, aging in the middle or innermost tensioning block requires the removal of all external accessories, including the tensioning ring, tensioning block, and aluminum sleeve, before replacement. Furthermore, the outer accessories must be reinstalled after replacement, making the disassembly and installation process cumbersome and significantly impacting work efficiency.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Combine Figure 1-3 This embodiment is described in detail. A device for facilitating replacement of a chuck tensioning block comprises: a tooling and a tensioning module, wherein the tensioning module is sleeved on the outside of the tooling; the tooling is an annular cylinder, and the annular cylinder is divided into a first section 1, a second section 2 and a connecting section 3; the first section 1 and the second section 2 are fixedly connected by the connecting section 3; the outer diameter of the first section 1 is equal to the diameter of the internal thread of the chuck; the outer diameter of the second section 2 is equal to the outer diameter of the chuck shaft; the outer diameter of the connecting section 3 is equal to the outer diameter of the second section 2; the second section 2 is provided with an opening 4 and a groove 5.

[0016] Furthermore, the tensioning module includes a tensioning block 6, an aluminum sleeve 7, a first tensioning ring 8, a second tensioning ring 9 and a spring 10; the aluminum sleeve 7 is provided with a square hole 11; the aluminum sleeve 7 is sleeved on the outside of the first tensioning ring 8; the first tensioning ring 8 is provided with a circular hole 12; the second tensioning ring 9 includes a ring portion 13 and a tooth portion 14, the spring 10 is sleeved on the tooth portion 14, and the end away from the ring portion 13 is inserted into the circular hole 12 of the first tensioning ring 8. Specifically, the ring portion 13 of the second tensioning ring 9 is divided into two types, Figure 2 The ring 13 in the middle is suitable for the tensioning module in the middle of the chuck. Figure 3 The ring portion 13 in the middle is suitable for the outermost tensioning module of the chuck.

[0017] Specifically, the aluminum sleeve 7 has six groups of equally spaced square holes 11, the end of the first tensioning ring 8 away from the spring 10 has six equally spaced wedge-shaped slopes, the bottom of the tensioning block 6 has a wedge-shaped slope and the top has two protrusions. During installation, the wedge-shaped slopes of the six tensioning blocks 6 are respectively matched with the wedge-shaped slopes of the first tensioning ring 8, and then the protrusions of the tensioning block 6 are extended from the square holes 11 of the aluminum sleeve 7.

[0018] Specifically, when the tensioning block 6 is aged and needs to be replaced, an annular spring is placed in the groove 5 provided in the tooling, the first tensioning ring 8 is sleeved on the second section 2, and the aluminum sleeve 7 is sleeved on the outside of the first tensioning ring 8. The tensioning block 6 passes through the opening 4, so that the wedge-shaped slope of the tensioning block 6 fits with the wedge-shaped slope of the first tensioning ring 8, so that the annular spring is clamped between the two protrusions of the tensioning block 6, and then the two protrusions extend from the square hole 11 of the aluminum sleeve 7. Repeat the installation of all six tensioning blocks 6, and then sleeve the spring 10 on the tooth portion 14 of the second tensioning ring 9, and insert the end away from the ring portion 13 into the circular hole 12 of the first tensioning ring 8 to complete the installation of the tensioning module. The first section 1 of the tooling is clamped with the internal thread of the chuck, and the tensioning module is pushed onto the chuck shaft to complete the replacement.

[0019] Furthermore, the outer diameter of the first section 1 is 92.8 mm, and the outer diameter of the second section 2 is 109.2 mm.

[0020] Furthermore, the length of the first section 1 is 40 mm, the length of the second section 2 is 100 mm, and the length of the connecting section 3 is 5 mm.

[0021] Furthermore, the thickness of the first section 1 is 7 mm, the thickness of the second section 2 is 4.5 mm, and the thickness of the connecting section 3 is 15.2 mm.

[0022] When the tension block 6 in the center of the chuck shaft ages and needs to be replaced, the tension module located outside it does not need to be replaced. To save time in disassembly and installation, a jig can be used. The first section 1 of the jig snaps into the internal threads of the chuck. The tension module that does not need to be disassembled and replaced is removed from the chuck shaft and fitted onto the second section 2 of the jig. The tension module that needs to be replaced with the tension block 6 is then removed and replaced, and the tension module fitted onto the jig is then pushed onto the chuck shaft. This jig saves time in disassembling and assembling the outer tension modules, greatly improving work efficiency. Without the jig, two workers would take 1.5 hours to disassemble and assemble a chuck. However, with the jig, replacing the tension block 6 by one person can be completed in just 0.5 hours, significantly improving work efficiency.

[0023] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
