Description

Technical Field

[0001] The utility model relates to the technical field of reamers, in particular to a split type reamer. Background Art

[0002] A reamer is a rotary tool with one or more teeth used to remove a thin layer of metal from the surface of a machined hole. A reamer is a rotary finishing tool with a straight or spiral edge, used for expanding or repairing holes. Due to its small cutting volume, the machining accuracy requirements of a reamer are usually higher than those of a drill. It can be operated manually or installed on a drilling machine.

[0003] During the use of existing reamers, they are usually of a single-body structure. During the subsequent processing, if the edge of the reamer is damaged, the entire reamer will be disassembled and replaced, but the shank is in an intact state. Replacing the entire reamer will increase the overall cost of use. For this reason, we propose a split reamer. Utility Model Content

[0004] In view of the above problems, the present invention provides a split reamer, which can solve the problems existing in the above background technology.

[0005] The technical solution of the utility model is:

[0006] A split reamer includes a reamer body, one end of the reamer body is fixedly connected to a first quick-connect mechanism, the end of the first quick-connect mechanism away from the reamer body is provided with a second quick-connect mechanism, the end of the second quick-connect mechanism away from the first quick-connect mechanism is fixedly connected to a fixed connecting handle, and a connection protection mechanism is movably sleeved on the outer sides of the surfaces of the reamer body, the first quick-connect mechanism and the second quick-connect mechanism.

[0007] In a further technical solution, the first quick-connect mechanism includes a connecting table, a side of the connecting table away from the reamer body is fixedly connected to a fixed connecting block, and a fixed mounting hole is provided on the outer side of the surface of the fixed connecting block.

[0008] In a further technical solution, the second quick-connect mechanism includes a connecting limit ring, a connecting mounting rod is fixedly connected to the side of the connecting limit ring away from the connecting cone, a fixing slot is opened inside the connecting limit ring, and a fastening bolt is provided inside the connecting limit ring.

[0009] In a further technical solution, the inner side of the fixed slot and the outer side of the surface of the fixed connection block are slidably fitted with each other, and the fastening bolt and the fixed installation hole are connected and fixed by threads.

[0011] In a further technical solution, a plurality of fixing grooves are provided at one end of the protective sleeve.

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

[0013] 1. The first quick-connect mechanism and the second quick-connect mechanism are provided, so that during the process of disassembly and assembly, the reamer can be assembled and used through the connection between the first quick-connect mechanism and the second quick-connect mechanism. When the reamer body is disassembled and replaced, only the reamer body and the first quick-connect mechanism need to be disassembled and replaced, which can effectively reduce the overall use cost and is easy to operate.

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

[0022] Example:

[0023] like Figure 1-Figure 4 As shown, a split reamer includes a reamer body 1, one end of the reamer body 1 is fixedly connected to a first quick-connect mechanism 2, an end of the first quick-connect mechanism 2 away from the reamer body 1 is provided with a second quick-connect mechanism 3, an end of the second quick-connect mechanism 3 away from the first quick-connect mechanism 2 is fixedly connected to a fixed connecting handle 4, and a connection protection mechanism 5 is movably sleeved on the outer sides of the surfaces of the reamer body 1, the first quick-connect mechanism 2 and the second quick-connect mechanism 3.

[0024] The working principle of the above technical solution is as follows:

[0025] During use, the first quick-connect mechanism 2 and the second quick-connect mechanism 3 are connected and cooperated with each other, so that the whole can be quickly assembled and used. Conversely, when the reamer body 1 is damaged, it is only necessary to disassemble and separate the first quick-connect mechanism 2 and the second quick-connect mechanism 3, and replace the reamer body 1 and the first quick-connect mechanism 2 separately. The structure is simple and the operation is convenient and fast. When the whole is not in use, the connection protection mechanism 5 can protect the reamer body 1, and the operation is convenient and fast.

[0026] In another embodiment, Figure 3 As shown, the first quick-connect mechanism 2 includes a connecting platform 6, and a fixed connecting block 7 is fixedly connected to the side of the connecting platform 6 away from the reamer body 1. A fixed mounting hole 8 is opened on the outer surface of the fixed connecting block 7.

[0027] It is convenient to insert the fixed connection block 7 into the inner side of the second quick connection mechanism 3, so that the fixed installation hole 8 and the second quick connection mechanism 3 are connected and matched, thereby quickly connecting and fixing, and the operation is convenient.

[0028] In another embodiment, Figure 3 As shown, the second quick-connect mechanism 3 includes a connecting limit ring 10, and the connecting limit ring 10 is fixedly connected to a connecting mounting rod 9 on the side away from the connecting table 6. A fixing slot 11 is opened inside the connecting limit ring 10, and a fastening bolt 12 is provided inside the connecting limit ring 10.

[0029] When the connecting block 7 is located inside the fixing slot 11 , the fastening bolt 12 is rotated and inserted into the interior of the connection limiting collar 10 and the inner side of the fixing hole 8 , thereby quickly performing the connection and fixing.

[0030] In another embodiment, Figure 3 As shown, the inner side of the fixed slot 11 and the outer side of the surface of the fixed connection block 7 are slidably fitted with each other, and the fastening bolt 12 is connected and fixed to the fixed installation hole 8 through a thread.

[0031] The connecting block 7 can be inserted into the inner side of the fixing slot 11 to facilitate the fixing, so that the whole can be stably transmitted when connected and fixed, and the operation is convenient.

[0032] In another embodiment, Figure 3 As shown, the connection protection mechanism 5 includes a protection sleeve 13 , an inner side of the protection sleeve 13 is provided with a limiting inclined surface 14 , and an inner end of the protection sleeve 13 is provided with a fixed limiting protrusion 15 .

[0033] It is convenient to put the protective sleeve 13 on the outside of the overall surface, so that the limiting slope 14 can fit together with the outside of the connecting cone 6, and at the same time, the fixed limiting protrusion 15 can be located at the edge of one end of the connecting mounting rod 9 close to the fixed slot 11, thereby limiting the installation.

[0034] In another embodiment, Figure 4 As shown, one end of the protective sleeve 13 is provided with a plurality of fixing slots 16 .

[0035] During the process of disassembling and assembling the protective sleeve 13 , the fixed limiting protrusion 15 and the connecting mounting rod 9 will squeeze each other, and the end of the protective sleeve 13 will expand under the action of the fixed through groove 16 , which is convenient for operation.

[0036] The working principle of the utility model is as follows: during use, when the whole is not in use, the protective sleeve 13 is sleeved on the outer surface of the whole from the direction of the fixed connecting handle 4, so that the protective sleeve 13 protects the reamer body 1, and at the same time the limiting inclined surface 14 and the connecting truncated cone 6 fit together, and at the same time the fixed limiting protrusion 15 can be sleeved on the edge of one end of the connecting mounting rod 9 close to the connecting limiting collar 10, thereby limiting the protective sleeve 13 and preventing the protective sleeve 13 from deflecting during use, thereby enabling the protective sleeve 13 to stably provide protection for the reamer body 1; During use, if the reamer body 1 is damaged and needs to be disassembled and replaced, it is only necessary to rotate and disassemble the fastening bolt 12 so that the fastening bolt 12 can be pulled out from the inner side of the fixed mounting hole 8 and the inside of the connecting limit ring 10, and the connection between the connecting limit ring 10 and the fixed connecting block 7 is no longer restricted. Then the reamer body 1, the connecting cone 6 and the fixed connecting block 7 are moved horizontally, so that the fixed connecting block 7 is pulled out from the inner side of the fixed slot 11, thereby quickly disassembling and replacing the reamer body 1 and the first quick-connect mechanism 2 as a whole. The structure is simple and the operation is convenient.

[0037] The above embodiments merely represent specific implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
