Technical Field

[0001] This utility model relates to the field of tool head machining technology, specifically a positioning device for CNC machine tool tool head machining. Background Technology

[0002] The tool turret is a core component in CNC machine tools used for automatic tool changing. Its function is to store multiple tools and quickly switch between them according to program instructions during machining, enabling continuous multi-process machining.

[0003] During production, the cutter head generally needs to be fixed and positioned to prevent displacement during drilling. The common positioning method is to use a clamp to clamp the two sides of the cutter head. However, some cutter heads need to have tool holder holes opened on the outside, and conventional two-side clamping and positioning devices will interfere with the opening of the tool holder holes, so improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for CNC machine tool tool head machining, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for CNC machine tool cutter head machining, comprising a cutter head body, a central hole, a machining table, and a positioning component. The cutter head body is placed on the top of the machining table, and a central hole is provided at the center of the cutter head body. Four sets of fixed sleeves are provided at the center of the top of the cutter head body via a bracket, and each fixed sleeve has a movable block inside. Each movable block has a guide post at its top and a positioning component at one end. A drive disk is provided above the fixed sleeves, and four sets of guide grooves are provided on the drive disk. A second drive motor is provided on the machining table below the drive disk, and the output end of the second drive motor is connected to the drive disk via a roller.

[0006] Preferably, a base is provided below the processing table, and a first drive motor is fixed at the top inside the base. The output end of the first drive motor is connected to the processing table through a roller.

[0007] Preferably, sliders are provided on both sides of the bottom of the processing table, and an annular groove matching the sliders is provided on the top surface of the base.

[0008] Preferably, the guide groove is formed in a concentric circle around the drive disk, and the top of each guide post extends above the guide groove.

[0009] Preferably, the positioning member has rubber protrusions evenly distributed on the side away from the drive disk, and the rubber protrusions are in contact with the inner wall of the central hole.

[0010] Preferably, one end of each positioning member is provided with an insert block, and the end of each movable block near the positioning member is provided with a slot that matches the insert block.

[0011] Preferably, screws pass through both sides of one end of the movable block, and a locking block is provided on the side of the screws near the insertion block.

[0012] Preferably, each of the insert blocks has a slot on the side near the card block, and each card block is embedded inside the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The positioning device for CNC machine tool tool head machining includes a tool head body, a center hole, a machining table, a drive plate, a second drive motor, a fixed sleeve, a movable block, a positioning element, a guide groove, and a guide column. The tool head body is placed on the top of the machining table, and the center hole of the tool head body passes through the drive plate.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 The present invention provides an embodiment of a positioning device for machining a CNC machine tool cutter head, comprising a cutter head body 1, a center hole 2, a machining table 4 and a positioning component 13. The cutter head body 1 is placed on the top of the machining table 4, and a center hole 2 is provided at the center of the cutter head body 1. The cutter head body 1 is placed on the top of the machining table 4.

[0023] Four sets of fixed sleeves 8 are provided at the center of the top of the cutter head body 1 via a bracket, and each fixed sleeve 8 is fitted with a movable block 9. Each movable block 9 is provided with a guide post 11 at the top and a positioning element 13 at one end.

[0024] A drive disk 3 is provided above the fixed sleeve 8, and four sets of guide grooves 10 are provided on the drive disk 3. A second drive motor 12 is provided on the processing table 4 below the drive disk 3, and the output end of the second drive motor 12 is connected to the drive disk 3 through a roller.

[0025] The guide groove 10 is formed in a concentric circle around the drive disk 3, and the top of the guide post 11 extends above the guide groove 10.

[0026] The center hole 2 of the cutter head body 1 passes through the drive disk 3. The second drive motor 12 drives the drive disk 3 to rotate. Four sets of guide grooves 10 are opened on the drive disk 3. The fixed sleeve 8 is set below the drive disk 3. Each fixed sleeve 8 is fitted with a movable block 9. Each movable block 9 is equipped with a guide post 11. Each guide post 11 passes through the guide groove 10.

[0027] When the drive disk 3 rotates, the geometric contour of the guide groove 10 forces the guide post 11 to move along a specific path, thereby causing the movable block 9 to extend out of the fixed sleeve 8, so that the positioning member 13 abuts against the inner wall of the center hole 2 of the cutter body 1, positioning the cutter body 1 without affecting the opening and processing of its side tool holder holes.

[0028] Rubber protrusions 16 are evenly distributed on the side of the positioning member 13 away from the drive disk 3, and the rubber protrusions 16 contact the inner wall of the central hole 2, which plays an anti-slip role and increases the stability of the positioning member 13 when it contacts the inner wall of the central hole 2.

[0029] A base 5 is provided below the processing table 4, and a first drive motor 6 is fixed at the top inside the base 5. The output end of the first drive motor 6 is connected to the processing table 4 through a roller.

[0030] The first drive motor 6 drives the machining table 4 to rotate, rotating the side of the cutter head body 1 to the position of the machining tool for drilling;

[0031] Both sides of the bottom of the processing table 4 are equipped with sliders 7. The top surface of the base 5 is provided with an annular groove 20 that matches the sliders 7. The material of the sliders 7 can be polytetrafluoroethylene (PTFE) to reduce friction. The shape and size of the annular groove 20 are matched according to the specific design of the sliders 7 to ensure that the processing table 4 slides smoothly on the base 5.

[0032] One end of each positioning component 13 is provided with a plug 19, and the end of each movable block 9 near the positioning component 13 is provided with a slot 18 that matches the plug 19. The plug 19 is made of hard alloy.

[0033] Both sides of one end of the movable block 9 are through which screws 14 pass, and each screw 14 is provided with a locking block 17 on the side of the insert block 19. Each insert block 19 is provided with a slot 15 on the side of the locking block 17, and the locking block 17 is embedded in the slot 15.

[0034] When it is necessary to replace the positioning component 13, the locking block 17 can be separated from the slot 15 by rotating the screw 14. Then the insert block 19 can be separated from the slot 18, thereby disassembling the positioning component 13. It can be adjusted and replaced according to the actual positioning requirements to meet different processing needs.

[0035] The specific model and specifications of the first drive motor 6 and the second drive motor 12 need to be determined by selection calculation based on the specifications and parameters of the device. The selection calculation method is existing technology, so it will not be described in detail here.

[0036] Working principle: In this embodiment, the cutter head body 1 is placed on top of the processing table 4. The center hole 2 of the cutter head body 1 passes through the drive disk 3. The second drive motor 12 drives the drive disk 3 to rotate. Four sets of guide grooves 10 are opened on the drive disk 3. The fixed sleeve 8 is set below the drive disk 3. Each fixed sleeve 8 is fitted with a movable block 9. Each movable block 9 is provided with a guide post 11. The guide post 11 passes through the guide groove 10. When the drive disk 3 rotates, the geometric contour of the guide groove 10 forces the guide post 11 to move along a specific path, thereby causing the movable block 9 to extend out of the fixed sleeve 8. This causes the positioning element 13 to abut against the inner wall of the center hole 2 of the cutter head body 1, positioning the cutter head body 1 without affecting the opening and machining of the side tool holder holes. Then, the first drive motor 6 drives the machining table 4 to rotate, rotating the side of the cutter head body 1 to the position of the machining tool for drilling. When it is necessary to replace the positioning element 13, the locking block 17 can be separated from the locking groove 15 by rotating the screw 14. Then the insert block 19 can be separated from the slot 18, thereby disassembling the positioning element 13. It can be adjusted and replaced according to the actual positioning requirements to meet different machining needs.
