Description
Technical Field
[0001] This utility model relates to the technical field of spline shaft processing equipment, specifically a cutting device for producing spline shafts with a dustproof structure. Background Technology
[0002] In the machinery manufacturing industry, splined shafts are key components for achieving torque transmission and motion coordination between mechanical parts. They are widely used in automotive transmission systems, industrial machine tools, construction machinery and other fields. The first step in the production of splined shafts is to cut the bar stock according to the design specifications to obtain blanks that meet the requirements of subsequent processing.
[0003] A search revealed that patent publication number CN219402588U discloses a cutting device for spline shaft processing, belonging to the field of spline shaft processing technology. The device includes a base, a collection box on the upper surface of the base, a vertical plate fixed to the upper surface of the base, a box body and a positioning cylinder on one side of the vertical plate, with the box body located below the positioning cylinder and movably mounted on the vertical plate. The positioning cylinder is fixedly connected to the vertical plate, and a positioning hole is provided on the positioning cylinder. A crossbar is fixed to one side of the positioning cylinder, and a collar is slidably mounted on the crossbar. A mounting plate is fixed to the bottom of the collar, and a cutting machine is mounted on the lower surface of the mounting plate. The box body is a cuboid structure with an open top, and a material discharge port is provided on the bottom wall of the box body. A push-pull structure is also provided on one side of the collar. This invention eliminates the need to adjust the position of the metal rod during each cut, ensuring consistent cutting length, reducing workload, and allowing for the cutting of blanks of different lengths, thus exhibiting high applicability.
[0004] Existing spline shaft production cutting equipment generates a large amount of metal shavings and fine dust during the high-speed friction between the cutting tool and the spline shaft material. This dust not only permeates the workshop air, deteriorating the production environment and threatening the respiratory health of operators, but also poses a risk of occupational diseases such as pneumoconiosis with long-term exposure. Furthermore, existing spline shaft production cutting equipment requires manual operation to adjust and fix the spline shaft material, affecting the processing efficiency. Therefore, a spline shaft production cutting equipment with a dustproof structure is designed. Utility Model Content

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In this utility model, through a series of structural arrangements, when the operator performs a cutting operation on the spline shaft material, after placing both ends of the spline shaft material to be cut into the V-shaped grooves at the top of the two lower fixed clamping plates, the operator closes the transparent door, starts the reduction motor and the first hydraulic telescopic rod, and allows external cutting fluid to be delivered into the input pipe. As the first hydraulic telescopic rod starts and drives the cutting mechanism to move downwards in the Y-axis direction, it also drives the upper fixed clamping plate to move downwards in the Y-axis direction. The upper fixed clamping plate will first contact the V-shaped grooves placed on the lower fixed clamping plates. When the spline shaft material comes into contact with the cutting mechanism, the upper fixed clamping plate exerts a certain force on the extrusion assembly as the cutting mechanism continues downward. The extrusion assembly compresses the material, and the rebound force generated by the compression is transmitted to the upper fixed clamping plate. The upper fixed clamping plate clamps the spline shaft on the lower fixed clamping plate. When the cutting mechanism continues downward, the cutting saw blade on the cutting mechanism cuts the spline shaft material that is clamped. Thus, this invention achieves automatic fixing of the cut spline shaft material without the need for manual adjustment, thereby improving production efficiency.
[0016] 2. In this utility model, through a series of coordinated structural arrangements, when the cutting saw blade on the cutting mechanism cuts the spline shaft material, the cutting fluid is transported to the input pipe through the external conveying structure and sprayed from the nozzle onto the cutting area of the spline shaft material. When the cutting fluid is sprayed onto the cutting area of the spline shaft material, it not only cools the cutting saw blade and the cutting area of the spline shaft material, but also prevents the dust generated during the cutting of the spline shaft material from filling the inside of the housing. It also prevents the dust inside the housing from rushing out when the operator opens the transparent door. Moreover, the spline shaft material is inside the housing during the cutting process, thus this utility model effectively avoids the situation where dust, debris and other substances generated during the cutting of the spline shaft material splash everywhere and pollute the working environment.

[0030] like Figure 1-8 As shown, a cutting device for producing splined shafts with a dustproof structure includes a housing 100. Inside the housing 100, a cutting mechanism 600 for cutting splined shaft raw materials is provided. On both sides below the cutting mechanism 600, there are fixing and clamping mechanisms 900 for fixing and clamping the splined shaft raw materials, and adjusting mechanisms 300 for adjusting the position of the fixing and clamping mechanisms 900 on the X-axis. Below the adjusting mechanisms 300, there is a guide channel 700 for guiding the flow of impurity-containing liquid. At the bottom of the housing 100, there is a filter channel 800 for receiving the impurity-containing liquid discharged from the guide channel 700 and filtering the impurities in the impurity-containing liquid. On both sides of the rear end wall of the housing 100, there are input pipes 400 for receiving cutting fluid. One end of the input pipe 400 is provided with a nozzle 410 for spraying cutting fluid onto the cutting area of the splined shaft raw materials, and the nozzle 410 is located inside the housing 100. The fixed clamping mechanism 900 is provided with an upper fixed clamping plate 920 and a lower fixed clamping plate 910 for fixing and clamping the spline shaft material. The fixed clamping mechanism 900 is also provided with a compression component 940 that will compress when subjected to a certain force in the Y-axis direction. The top of the housing 100 is provided with a first hydraulic telescopic rod 200 for moving the cutting mechanism 600, the extrusion assembly 940 and the upper fixed clamping plate 920 in the Y-axis direction.
[0031] The cutting mechanism 600 is provided with a lifting plate 610, and a side plate 611 is installed on the lower surface of the lifting plate 610. A second rotating shaft 640 is installed in the bearing on the outer wall of the side plate 611. A cutting saw blade 650 is provided on the circumferential outer wall of the second rotating shaft 640. One end of the second rotating shaft 640 is connected to one end of the first rotating shaft 630 through a bevel gear set.
[0032] The other end of the first rotating shaft 630 passes through a bearing on the surface of the lifting plate 610 and is connected to the output shaft of the reduction motor 620 via a bevel gear set. The reduction motor 620 is installed on one side of the upper surface of the lifting plate 610. Slide rails 612 are installed on both sides of the lower surface of the lifting plate 610. The outer wall of the lifting plate 610 and the inner wall of the housing 100 are in clearance fit. Because the outer wall of the lifting plate 610 and the inner wall of the housing 100 are in clearance fit, the movement of the lifting plate 610 can be limited and guided. When the reduction motor 620 starts, it drives the first rotating shaft 630 to rotate through the bevel gear set. When the first rotating shaft 630 rotates, it drives the second rotating shaft 640 to rotate through the bevel gear set. When the second rotating shaft 640 rotates, it drives the cutting saw blade 650 to rotate.
[0033] The first hydraulic telescopic rod 200 is installed at the center of the top of the housing 100, and the telescopic end of the first hydraulic telescopic rod 200 extends through the top of the housing 100 into the interior of the housing 100 and is connected to the lifting plate 610.
[0034] The adjustment mechanism is equipped with a second hydraulic telescopic rod 310, which is installed on the outer wall of the housing 100. The telescopic end of the second hydraulic telescopic rod 310 extends through the outer wall of the housing 100 into the interior of the housing 100 and connects to the movable plate 330. Both the front and rear ends of the outer wall of the movable plate 330 are provided with through holes, and a guide rod 320 is installed in the through holes of the movable plate 330. The outer wall of the guide rod 320 and the through hole of the movable plate 330 are clearance fit. One end of the guide rod 320 is installed on the inner wall of the housing 100. When the second hydraulic telescopic rod 310 is activated, it will drive the movable plate 330 to move linearly in the X-axis direction. When the movable plate 330 moves linearly in the X-axis direction, it will drive the fixed clamping mechanism 900 to move linearly in the X-axis direction, thereby adjusting the distance between the two fixed clamping mechanisms 900. The distance between the two fixed clamping mechanisms 900 is adjustable, so that splined shafts of different lengths can be fixed in principle.
[0035] The extrusion assembly 940 is provided with a mounting post 941. A mounting groove is opened at the center of the bottom end of the mounting post 941. An extrusion plate 943 is provided inside the mounting groove. The outer wall of the extrusion plate 943 and the groove wall of the mounting groove are in clearance fit. Because the outer wall of the extrusion plate 943 and the groove wall of the mounting groove are in clearance fit, the movement of the extrusion plate 943 can be limited and guided. The extrusion plate 943 is installed at one end of the connecting post 944, and the other end of the connecting post 944 passes through the mounting groove and extends to the outside. A spring 942 is provided between the top end of the extrusion plate 943 and the top end inside the mounting groove. A slider 930 is mounted on the top of the mounting post 941. The other end of the slider 930 is mounted on the slide rail 612, and the slider 930 and the slide rail 612 are slidably connected. The slider 930 and the slide rail 612 can limit and guide the movement of the fixed clamping mechanism 900 in the X-axis direction.
[0036] The other end of the connecting column 944 is equipped with an upper fixed clamping plate 920, which is located directly above the lower fixed clamping plate 910. Guide columns 921 are installed at the four corners of the bottom of the upper fixed clamping plate 920. The other end of the guide column 921 passes through the inner wall of the damping sleeve 950 and extends to the outside. The damping sleeve 950 is set in the mounting hole, which is opened on the surface of the lower fixed clamping plate 910 and the moving plate 330. The lower fixed clamping plate 910 is installed at the top of the moving plate 330. The structure of guide column 921, spring 942 and damping sleeve 950 can play a role in shock absorption when the cutting saw blade 650 cuts the splined shaft material and generates a certain vibration, thereby reducing the vibration generated by the cutting saw blade 650 cutting the splined shaft material and improving the cutting quality of the splined shaft material.
[0037] Inclined guide blocks 710 are installed on both sides of the bottom of the guide channel 700. A drain outlet 720 is provided between the two inclined guide blocks 710 and is located on one side of the bottom of the guide channel 700. The inclined guide blocks 710 can guide the impurity liquid falling into the guide channel 700 and discharge it from the drain outlet 720. Mounting blocks are provided on both outer walls of the guide channel 700. The other end of the mounting block is installed in a groove. The outer wall of the mounting block and the groove wall are in clearance fit. The groove is located below the inner walls of both sides of the housing 100. Because the outer wall of the mounting block and the groove wall are in clearance fit, the operator can disassemble and clean the guide channel 700.
[0038] A plate filter screen 810 is installed on one side of the interior of the filter tank 800. Both ends of the plate filter screen 810 are installed in the U-shaped grooves on the U-shaped clamping plate, and the end walls of the plate filter screen 810 and the groove walls of the U-shaped grooves are in clearance fit. Because the end walls of the plate filter screen 810 and the groove walls of the U-shaped grooves are in clearance fit, it is convenient for the staff to disassemble, replace or clean the plate filter screen 810. The U-shaped clamping plate is installed on the front and rear ends inside the filter tank 800. A drain pipe is installed on the lower side of the outer wall of one side of the filter tank 800. A valve body is installed on the drain pipe. The other end of the drain pipe is connected to the output pipe 500 through a pipe joint. The other end of the output pipe 500 passes through the outer wall of one side of the housing 100 and extends to the outside. The liquid filtered in the filter tank 800 will be discharged from the drain pipe into the output pipe 500. The output pipe 500 can transport the filtered cutting fluid to the external conveying structure, which can form a cutting fluid recycling. The front wall of the housing 100 is provided with a transparent door, which makes it easy for staff to observe the cutting process inside the housing 100. The top of the housing 100 is provided with ventilation slots.
[0039] Working principle: When in use, connect the external power supply. When the operator is cutting the splined shaft material, place both ends of the material into the V-grooves at the top of the two lower fixed clamping plates 910. Then, close the transparent door, start the reduction motor 620 and the first hydraulic telescopic rod 200, and supply external cutting fluid to the input pipe 400. The first hydraulic telescopic rod 200 starts and drives the cutting mechanism 600 downwards along the Y-axis, which in turn drives the upper fixed clamping plate 920. Moving downwards along the Y-axis, the upper fixed clamping plate 920 first contacts the splined shaft material placed on the lower fixed clamping plate 910. As the cutting mechanism 600 continues downwards, the upper fixed clamping plate 920 exerts a certain force on the extrusion assembly 940, causing it to compress. The rebound force generated by the compression of the extrusion assembly 940 is transmitted to the upper fixed clamping plate 920, which then clamps the splined shaft on the lower fixed clamping plate 910. When the cutting mechanism 600 continues downwards... The cutting saw blade 650 on the cutting mechanism 600 cuts the splined shaft material that is fixed and clamped. This invention achieves automatic fixing of the cut splined shaft material without the need for manual adjustment, thus improving production efficiency. When the cutting saw blade 650 on the cutting mechanism 600 cuts the splined shaft material, cutting fluid is delivered to the input pipe 400 through an external conveying structure and sprayed from the nozzle 410 onto the cutting area of the splined shaft material. When the cutting fluid is sprayed onto the cutting area of the splined shaft material, it not only cools the cutting saw blade 650 and the cutting area of the splined shaft material, but also prevents dust generated during the cutting of the splined shaft material from filling the interior of the housing 100. It also prevents dust from escaping to the outside when workers open the transparent door. Furthermore, since the splined shaft material is cut inside the housing 100 during the cutting process, this invention effectively prevents dust, debris, and other substances generated during the cutting of the splined shaft material from splashing everywhere and polluting the working environment.
[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
