Description

Technical Field

[0001] This utility model relates to the field of rack processing technology, specifically to a chamfering device for rack processing. Background Technology

[0002] Before chamfering, the teeth of a rack (including the tooth tip, tooth root, and tooth end) usually have sharp edges or burrs. The core function of chamfering is to eliminate these defects. Racks typically mesh with gears; if the rack teeth have sharp edges, they may scratch the gear teeth during meshing, leading to decreased fit accuracy, accelerated wear, and shortened gear lifespan. During the installation, adjustment, and maintenance of racks, operators may come into contact with the rack teeth, and the sharp edges can easily cut their hands. Chamfering reduces this safety hazard.

[0003] A search revealed a rack chamfering device with application number 201720531896.5, comprising a base, a guide rail, an electric grinding head assembly, and a worktable. The guide rail is located on the base behind the worktable and is parallel to the worktable. A sliding seat is provided on the guide rail, and a motor is mounted on the sliding seat. A vertical column is also fixed on the sliding seat, and a cantilever is fitted onto the column. A horizontal mounting hole is provided on the side of the cantilever, and a swing shaft is installed in the mounting hole. The swing shaft can swing around the mounting hole, and a clamp is fixedly connected to the front end of the swing shaft. The electric grinding head assembly is fixed to the clamp, and limit switches are provided at both ends of the guide rail. This utility model can process longer racks and has a high degree of automation, thus improving production efficiency.

[0004] In practical applications, the above-mentioned technical solutions have also revealed some problems. Among them, the most prominent problem is that when chamfering the rack, the metal shavings generated during the chamfering process are extremely inconvenient to handle. These metal shavings will fly everywhere, which will not only pollute the working environment and increase the subsequent cleaning workload, but may also fall onto various parts of the device, affecting the normal operation of the device, or even damaging the precision parts of the device and shortening the service life of the device.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Example 1:

[0032] Please see Figures 1-5 This is the first embodiment of the present invention.

[0033] This embodiment provides a chamfering device for rack machining, including a machining base 1 and a machining cover 2. The machining cover 2 is detachably installed on the upper surface of the machining base 1. It also includes a cooling circulation component 3, a driving machining component 4, a fixing component 5, and a regulating component 6. The cooling circulation component 3 is installed inside and outside the machining base 1, the driving machining component 4 is installed inside and outside the machining cover 2, the regulating component 6 is installed inside the upper part of the machining base 1, and the fixing component 5 is installed on the upper part of the regulating component 6.

[0034] Specifically, the cooling circulation assembly 3 includes a liquid tank 301 and a liquid pump 302. The liquid tank 301 is fixedly installed at the front end of the processing base 1, and the liquid pump 302 is fixedly installed on the upper end face of the liquid tank 301. The cooling circulation assembly 3 also includes a liquid delivery pipe 303 and a nozzle 304. The output end of the liquid pump 302 is connected to the liquid delivery pipe 303, and the output end of the liquid delivery pipe 303 passes through the inner wall of the processing cover 2 and is fixedly installed with the nozzle 304. The cooling circulation assembly 3 also includes a filter screen 305 and a connecting pipe 306. The filter screen 305 is fixedly installed inside the liquid tank 301, and the connecting pipe 306 passes through the inner side wall of the liquid tank 301. The cooling circulation assembly 3 also includes a collection tank 307 and a flow hole 308. The collection tank 307 is opened at the bottom end inside the processing base 1, and the upper end face of the processing base 1 is provided with a flow hole 308 that communicates with the collection tank 307.

[0035] Furthermore, the liquid pump 302 can extract the liquid from the liquid tank 301 and transport the liquid to the nozzle 304 through the liquid delivery pipe 303. The nozzle 304 can be used to cool the chamfered area.

[0036] Specifically, the control component 6 includes a mounting plate 601, an electric cylinder 602, a guide block 603, a guide groove 604, and a mounting slot 605. The mounting slot 605 is located inside the middle of the upper end face of the processing base 1. The electric cylinder 602 is fixedly installed on the bottom end face of the mounting slot 605. The mounting plate 601 is fixedly installed on the output end of the electric cylinder 602. The guide block 603 is fixedly installed on both side walls of the mounting plate 601. The guide groove 604 is opened on the outer side of the guide block 603 on the processing base 1.

[0037] Furthermore, by designing the mounting plate 601, the rack to be processed can be mounted. The operation of the electric cylinder 602 can drive the mounting plate 601 to slide in the mounting groove 605, thereby adjusting the height of the mounting plate 601, which can ensure that the rack has a suitable processing height.

[0038] Specifically, the fixing component 5 includes a pressurizing pipe 501, a control valve 502, a pressurizing seat 503, a pressurizing groove 504, and a clamping plate 505. The pressurizing pipe 501 is fixedly connected to the side wall of the liquid conveying pipe 303. The control valve 502 is fixedly installed in the middle position of the pressurizing pipe 501. The pressurizing seat 503 is fixedly installed on both sides of the upper end face of the mounting plate 601. The pressurizing groove 504 is opened inside the pressurizing seat 503. The clamping plate 505 is slidably installed inside the pressurizing groove 504.

[0039] Furthermore, the fixed component 5 can clamp and fix the rack to be processed, thus ensuring the stability of the rack during processing.

[0040] In use, when the rack needs to be machined, open the door panel of the machining cover 2 to place the clamping plate on the mounting plate 601. At this time, start the liquid pump 302. The liquid pump 302 can draw out the liquid from the liquid tank 301 and deliver the liquid to the pressure pipe 501 through the liquid delivery pipe 303. Open the control valve 502, and the liquid in the pressure pipe 501 can flow into the pressure groove 504 of the pressure seat 503. The increase of liquid in the pressure groove 504 can push the symmetrical clamping plate 505 to clamp and fix the rack. When machining, start the electric cylinder 602. The electric cylinder 602 can drive the mounting plate 601 to slide in the mounting groove 605. Through the guide block 603 and the guide groove 605 The 04 mechanism ensures stability during height adjustment, allowing for adjustment of the mounting plate 601's height. During processing, the liquid pump 302 extracts liquid from the liquid tank 301 and delivers it to the nozzle 304 via the liquid delivery pipe 303. The nozzle 304 cools the chamfered area, and the cooled liquid carries away the machining chips, allowing the liquid and chips to flow into the flow hole 308. The flow hole 308 is connected to the collection tank 307, which collects the machining chips and liquid, allowing them to settle to the bottom. Simultaneously, some liquid flows into the liquid tank 301 through the connecting pipe 306, where it is filtered by the filter screen 305 for recycling.

[0041] In summary, the use of liquid-pressurized symmetrical clamping plates 505, with the increase in liquid volume within the pressurization tank 504, achieves clamping of the rack. Compared to mechanical clamping, this method provides more uniform force, reducing damage to the rack surface. The symmetrical clamping design ensures the rack does not shift or wobble during processing, guaranteeing the accuracy of the chamfering. During processing, the nozzle 304 directly sprays liquid onto the chamfer, quickly dissipating the heat generated during processing and effectively reducing the temperature of the processing area. This prevents the rack from deforming due to high temperatures, protects the cutting tool, and extends its lifespan. The cooled liquid carries away machining chips, flowing through the flow hole 308 into the collection tank 307, achieving simultaneous cooling and chip removal. This reduces chip accumulation and interference with processing, ensuring a smooth processing flow.

[0042] Example 2:

[0043] Please see Figures 1-5 This is the second embodiment of the present utility model.

[0044] Specifically, the driving processing component 4 includes a drive motor 401 and a ball screw 402. The drive motor 401 is fixedly installed on the side wall of the processing cover 2. The output end of the drive motor 401 passes through the side wall of the processing cover 2 and is fixedly connected to the ball screw 402. The driving processing component 4 also includes a limiting groove rail 403, a ball nut slider 404, and a fixing seat 405. The limiting groove rail 403 is fixedly installed on the upper end surface inside the processing cover 2. The ball nut slider 404 is slidably installed inside the limiting groove rail 403. The fixing seat 405 is fixedly installed on the bottom end surface of the ball nut slider 404. The driving processing component 4 also includes a grinding motor 406 and a grinding wheel 407. The grinding motor 406 is fixedly installed on the lower end surface of the fixing seat 405. The grinding wheel 407 is fixedly installed on the output end of the grinding motor 406.

[0045] Furthermore, the ball screw 402 and the ball nut slider 404 form a conventional ball screw transmission component, which can ensure the stability of the rack during movement. At the same time, the grinding motor 406 can drive the grinding wheel 407 to rotate, so that the rack can be ground and chamfered by the grinding wheel 407.

[0046] In use, the drive motor 401 is started, and the drive motor 401 drives the ball screw 402 to rotate. The rotation of the ball screw 402 drives the ball nut slider 404 to slide in the limit groove 403. This allows the ball nut slider 404 to move the fixed seat 405. The movement of the fixed seat 405 can drive the grinding motor 406 to move, thus facilitating the adjustment of the grinding position. At the same time, the grinding motor 406 is started, and the grinding motor 406 drives the grinding wheel 407 to rotate. This allows the grinding wheel 407 to perform grinding and chamfering on the rack.

[0047] In summary, the transmission method using a drive motor 401 and a ball screw 402 offers higher transmission accuracy and stability compared to traditional gear or belt drives. The helical structure of the ball screw 402 precisely converts the rotational motion of the motor into the linear motion of the ball nut slider 404, thereby achieving precise adjustment of the position of the grinding wheel 407 and meeting the processing requirements of different rack chamfer positions. The guide and constraint of the ball nut slider 404 by the limiting rail 403 effectively prevents offset or wobbling during adjustment, further ensuring the accuracy of position adjustment and the consistency of chamfer dimensions. Due to the precise position adjustment and smooth movement, the contact position and pressure between the grinding wheel 407 and the rack are easier to control, avoiding problems such as excessively large, small, or uneven chamfers caused by positional deviations, thus ensuring the stability of processing quality.
