[0014] Beneficial effects

[0015] This invention provides a high-precision CNC broach grinding machine. Compared with the prior art, it has the following advantages:

[0016] Firstly, this utility model sprays water during grinding wheel operation, which effectively reduces the temperature of the grinding area, preventing damage to the grinding wheel and broach due to overheating. Simultaneously, the water spray also acts as a lubricant, reducing friction between the grinding wheel and broach, improving grinding efficiency and quality, increasing grinding precision and surface finish, and effectively reducing airborne debris, thereby improving the working environment and reducing the health hazards of dust to operators. Water containing waste debris flows directly into the water collection housing through the through-hole for quick removal of these waste debris and wastewater.

[0017] Secondly, when water containing waste debris flows directly into the water collection shell through the through hole, the filter screen first filters and collects the debris in the water. Then, the filtered water flows to the bottom of the water collection shell for recycling, reducing water waste. The filter screen is positioned and engaged on the positioning slot and positioning column of the support frame on the limiting bracket, which facilitates the direct disassembly of the filter screen and collection and utilization of the filtered metal debris, reducing resource waste.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a high-precision CNC broach grinding machine, including a grinding machine base 1, on which a processing mechanism for the high-precision CNC broach grinding machine is provided, the processing mechanism including:

[0026] The processing assembly includes a support platform 2 fixed to the upper surface of a grinding machine base 1. The support platform 2 has uniformly spaced through holes 201. A first positioning rod 5 is fixed to the inner wall of the support platform 2. A first mounting seat 501 connected to the outer wall of the first positioning rod 5 via a telescopic assembly is slidably mounted on the outer wall of the first positioning rod 5. A clamping assembly for broaching is located at the left end of the support platform 2. A grinding machine processing seat 7 is fixedly connected to the rear wall of the grinding machine base 1. A movable cavity 703 is formed inside the grinding machine processing seat 7. Two sets of second positioning rods 8 are fixedly connected to the inner wall of the movable cavity 703. A slide rail bracket 801 slides on the outer wall of the second positioning rods 8. A slider 802 driven by a screw is located inside the slide rail bracket 801. A grinding wheel 806 adjustable via a gear assembly is located at the front end of the slider 802. The grinding wheel 806 is adjusted during the grinding process. During adjustment of step 6, the slide rail bracket 801 is driven by a screw to adjust its vertical position on the second positioning rod 8. Then, the slide rail bracket 801, driven by the screw, moves the slider 802, which has a T-shaped structure and slides inside the slide rail bracket 801. This causes the grinding wheel 806 to adjust horizontally, achieving omnidirectional adjustment of the grinding wheel 806. Specifically, through the vertical adjustment of the slide rail bracket 801 and the horizontal sliding of the slider 802, the position of the grinding wheel 806 can be precisely controlled, ensuring that the precision requirements during grinding are met. The second positioning rod 8 and the T-shaped slider 802 ensure increased stability of the sliding of the slide rail bracket 801 and slider 802 during adjustment. (See details...) Figure 2 ;

[0027] The collection component includes a water collection housing 3 that is slidably connected inside the grinding machine base 1, and a filter plate 4 connected by a positioning component is provided inside the water collection housing 3.

[0028] In a preferred embodiment, a water tank 701 is fixed to the rear side wall of the grinding machine base 7. A connecting hose 702 connected to a water pump is provided inside the water tank 701. One end of the connecting hose 702 is located inside the water tank 701, and the other end is fixedly connected to a fixing plate 10. The fixing plate 10 is located on the side wall of the drive body 805 and is used to spray water on the grinding wheel 806 during operation. This can effectively reduce the temperature of the grinding area and prevent the grinding wheel 806 and the broach from being damaged due to overheating. At the same time, the water spray can also play a lubricating role, reducing the friction between the grinding wheel 806 and the broach, improving grinding efficiency and quality, improving grinding accuracy and surface quality, and effectively reducing airborne debris, thereby improving the working environment and reducing the health hazards of dust to operators. Water containing waste debris flows directly into the interior of the water collection housing 3 through the through hole 201 for collection, which can quickly clean up these waste debris and sewage.

[0029] In a preferred embodiment, the telescopic assembly includes a first electric push rod 502 fixed to the right end of the support platform 2, a first mounting base 501 fixedly connected to the telescopic end of the first electric push rod 502, and a sliding connection between the first mounting base 501 and the first positioning rod 5. The first mounting base 501 slides on the first positioning rod 5 via the first electric push rod 502, and is adjusted according to the length of the broach being processed, adapting to the processing requirements of broaches of different lengths, increasing the flexibility and applicability of the equipment, and enabling it to handle more types of broach processing tasks.

[0030] In a preferred embodiment, the clamping assembly includes a second mounting base 6 fixedly connected to the left end of the support platform 2. The second mounting base 6 contains a mounting plate 601 rotatably connected to a rotating shaft. Second electric push rods 602 are fixed to the upper and lower ends of the mounting plate 601. Clamping blocks 603 are fixed to the telescopic ends of the second electric push rods 602. The broach to be processed is placed between the two sets of clamping blocks 603. Then, the two sets of second electric push rods 602 are driven to bring the two sets of clamping blocks 603 closer together, thereby fixing the broach. This ensures the stability and accuracy of the broach during processing, helps reduce vibration and offset during processing, and thus improves processing accuracy and finished product quality. The electric push rods enable rapid and accurate adjustment, reducing the time and difficulty of manual operation and helping to improve processing efficiency.

[0031] In a preferred embodiment, the gear assembly includes a drive shaft 803 rotatably connected to the front end of the slider 802. A mounting block 804 is fixed to the outer wall of the drive shaft 803. A drive body 805 is fixed to the front end face of the mounting block 804. A grinding wheel 806 is located at the output end of the drive body 805. A drive gear 9, driven by a motor, is provided on the side wall of the slider 802. A transmission gear 901 is fixed to the extended end of the drive shaft 803. The drive gear 9 and the transmission gear 901 are meshed. A fixing plate 10 is fixed to the side wall of the drive body 805. The grinding wheel 806 rotates through the drive body 805. The drive body 805 is connected to the mounting block 804 via... The drive shaft 803 moves on the slider 802. When adjusting the angle of the grinding wheel 806, the drive gear 9 is driven by a motor, which in turn drives the drive shaft 803 on the transmission gear 901 to adjust the angle of the grinding wheel 806. The drive gear 9 is larger than the transmission gear 901, which can reduce the transmission ratio error of the gear transmission and improve the accuracy of the angle adjustment. The equipment can more easily adapt to the adjustment requirements of the grinding wheel 806 at different angles. Whether processing broaches of different shapes or adjusting processing parameters, the angle of the grinding wheel 806 can be adjusted quickly and accurately, improving the adaptability and flexibility of the equipment.

[0032] In a preferred embodiment, the positioning component includes a limiting bracket 301 fixedly connected to the inner wall of the water collection housing 3. Positioning posts 302 are fixed at four ends of the upper surface of the limiting bracket 301. A support frame 304 is attached to the surface of the limiting bracket 301. Positioning grooves 303 corresponding to the positioning posts 302 are opened at four ends of the support frame 304. The filter plate 4 is fixedly connected to the inner wall of the support frame 304. When water containing waste debris flows directly into the interior of the water collection housing 3 through the through hole 201 for collection, the debris in the water is first filtered and collected by the filter plate 4. Then, the filtered water flows to the bottom of the water collection housing 3 for recycling, reducing water waste. The filter plate 4 is positioned and engaged on the limiting bracket 301 via the support frame 304, positioning grooves 303, and positioning posts 302, facilitating direct disassembly of the filter plate 4 to collect and utilize the filtered metal debris, further reducing resource waste.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, the slide rail bracket 801 is adjusted vertically via a screw drive on the second positioning rod 8. Then, the slide rail bracket 801, driven by the screw, moves the slider 802, which has a T-shaped structure and slides inside the slide rail bracket 801. This causes the grinding wheel 806 to be adjusted horizontally, achieving omnidirectional adjustment of the grinding wheel 806. The broach to be machined is then placed between two sets of clamping blocks 603. The two sets of second electric push rods 602 are then driven to bring the two sets of clamping blocks 603 closer together, thus fixing the broach. This ensures the stability and accuracy of the broach during machining. To help reduce vibration and offset during processing, the connecting hose 702 is located inside the water tank 701 at one end and fixedly connected to the fixing plate 10 at the other end. The fixing plate 10 is located on the side wall of the drive body 805 and is used to spray water on the grinding wheel 806 during operation. This can effectively reduce the temperature of the grinding area and prevent the grinding wheel 806 and broach from being damaged due to overheating. When water containing waste chips flows directly into the water collection shell 3 through the through hole 201 for collection, the chips in the water are first filtered and collected by the filter screen plate 4. Then the filtered water flows to the bottom of the water collection shell 3 for recycling.

[0035] When adjusting the grinding wheel 806, the drive gear 9 is driven by a motor, which in turn drives the transmission shaft 803 on the transmission gear 901 to adjust the angle of the grinding wheel 806. The drive gear 9 is larger than the transmission gear 901, which can reduce the transmission ratio error of the gear transmission and improve the accuracy of the angle adjustment. The equipment can more easily adapt to the adjustment requirements of the grinding wheel 806 at different angles. Since the motor and water pump mentioned above are all existing technologies, they will not be elaborated on further.
