Description

Technical Field

[0001] This utility model relates to the field of gear shaping cutter technology, and in particular to a gear shaping cutter tool changing mechanism. Background Technology

[0002] A gear shaper is a cutting tool used for gear machining. It is mainly used to machine spur and helical cylindrical gears on gear shapers, and can also be used to machine racks, internal gears, non-circular gears, etc. It is one of the key tools in the gear manufacturing field.

[0003] During the use of gear shaping cutters, they need to be replaced and maintained regularly. When replacing them, a tool changing mechanism is required. However, traditional tool changing mechanisms have some problems. When changing gear shaping cutters, it is inconvenient to pre-clamp the newly replaced cutter, which makes it more troublesome to fix it later. Therefore, a gear shaping cutter tool changing mechanism is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a gear shaping cutter tool changing mechanism to solve the problem that the replacement of existing gear shaping cutters is relatively troublesome.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a gear shaping cutter tool changing mechanism, including a gear shaping cutter and a tool holder;

[0006] The top end of the gear shaping cutter is equipped with a tool holder, the bottom end of the tool holder is equipped with an installation sleeve, and the interior of the installation sleeve is provided with a pre-clamping structure.

[0007] The pre-clamping structure includes a mounting cavity, which is located inside the top of the mounting sleeve. A telescopic spring is installed inside the mounting cavity, and a clamping plate is installed on one side of the telescopic spring. A clamping groove is provided on the outer side of the top of the gear cutter.

[0008] Preferably, one end of the telescopic spring is fixed to one side of the mounting cavity, and the other end of the telescopic spring is fixed to one side of the clamping plate, forming a telescopic structure between the telescopic spring and the clamping plate.

[0009] Preferably, the clamping plates are provided in multiple sets, and the multiple sets of clamping plates are arranged in a ring inside the mounting sleeve.

[0010] Preferably, a tool changing structure is provided on the outer side of the mounting sleeve. The tool changing structure includes a fixed sleeve, which is installed on the outer side of the mounting sleeve. A movable cavity is formed inside the fixed sleeve, and a pressing block is installed inside the movable cavity. A movable block is installed on one side of the pressing block, and a rotating rod is installed at the top of the movable block.

[0011] Preferably, a fixing rod is installed on one side of the movable block, a fixing groove is formed inside the outer side of the gear cutter, an installation groove is formed on one side of the inside of the movable cavity, a return spring is installed inside the installation groove, and one side of the return spring is fixed to one side of the movable block.

[0012] Preferably, multiple sets of fixing rods are provided, and the multiple sets of fixing rods and fixing grooves form an insertion structure.

[0013] Preferably, the rotating rod passes through the interior of the top end of the fixed sleeve, and the rotating rod and the fixed sleeve form a threaded connection.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By incorporating a pre-clamping structure, the gear shaping cutter is made easier to fix during tool changes. The clamping plate and the telescopic spring work together to press one side of the clamping plate into the clamping groove, thus pre-clamping the gear shaping cutter and making it easier to fix it in the future.

[0016] By incorporating a tool changing mechanism, when changing and fixing the gear hobbing cutter, the rotating rod can push the extrusion block downwards, causing the extrusion block to press the moving block to one side. This allows the fixing rod on one side of the moving block to be inserted into the fixing groove, thus fixing the gear hobbing cutter. The use of multiple sets of fixing rods improves the fixing effect of the gear hobbing cutter, thereby completing the tool changing and fixing work of the gear hobbing cutter.

[0024] This utility model embodiment provides a gear shaper tool changing mechanism, such as... Figures 1-5 As shown, it includes a gear shaping cutter 1 and a tool holder 3; the top of the gear shaping cutter 1 is equipped with a tool holder 3, the bottom of the tool holder 3 is equipped with an installation sleeve 4, and the interior of the installation sleeve 4 is provided with a pre-clamping structure 5;

[0025] The pre-clamping structure 5 includes a mounting cavity 501, which is located inside the top of the mounting sleeve 4. A telescopic spring 502 is installed inside the mounting cavity 501, and a clamping plate 503 is installed on one side of the telescopic spring 502. A clamping groove 504 is provided on the outer side of the top of the gear cutter 1. One end of the telescopic spring 502 is fixed to one side of the mounting cavity 501, and the other end of the telescopic spring 502 is fixed to one side of the clamping plate 503. The telescopic spring 502 and the clamping plate 503 form a telescopic structure. Multiple sets of clamping plates 503 are provided, and the multiple sets of clamping plates 503 are arranged in a ring inside the mounting sleeve 4.

[0026] In a further preferred embodiment of this utility model, such as Figures 1-3 As shown: When changing the gear shaping cutter 1, after removing the old gear shaping cutter 1, the new gear shaping cutter 1 is installed into the mounting sleeve 4. During installation, the new gear shaping cutter 1 is inserted into the mounting sleeve 4. After the gear shaping cutter 1 is inserted into the mounting sleeve 4, the outer side of the top of the gear shaping cutter 1 will press the clamping plate 503 to one side and press the telescopic spring 502 to retract. After the gear shaping cutter 1 is inserted into the mounting sleeve 4, the telescopic spring 502 will press the clamping plate 503 to one side, so that one side of the clamping plate 503 is pressed into the clamping groove 504, thus completing the pre-clamping of the gear shaping cutter 1.

[0027] A tool changing structure 2 is provided on the outer side of the mounting sleeve 4. The tool changing structure 2 includes a fixed sleeve 201, which is installed on the outer side of the mounting sleeve 4. A moving cavity 203 is formed inside the fixed sleeve 201. A pressing block 204 is installed inside the moving cavity 203. A moving block 205 is installed on one side of the pressing block 204.
