Description

Technical Field

[0001] The invention relates to the field of machining, in particular to a composite machine tool for turning, hobbing, grinding and quenching gears. Background Art

[0002] A compound machine tool is a machine tool that can complete or complete as much as possible the processing of multiple elements from rough to finished product on a single host. Compound machine tools are generally CNC machine tools or machining centers, that is, compound CNC machine tools or compound machining centers.

[0003] After searching, a turning and milling compound machine tool was disclosed, with announcement number: CN103302498A, including a supporting device, a frame, an electric control box, and an oil cooling system, characterized in that: a spindle box is arranged in the middle of the frame, a shaft material advancing device is arranged on the left side of the spindle box, a feeding device is arranged on the right side of the spindle box, a turning tool fixing mechanism is arranged in the horizontal direction of the feeding device, and a gear hobbing mechanism is arranged in the vertical direction; an auxiliary fixing device is arranged on the right side of the turning tool fixing mechanism and the gear hobbing mechanism.

[0005] Secondly, in the final step of processing, the parts are cut off by a cutting tool, but the existing related composite machine tools do not have a corresponding stabilizing mechanism, including the invention, resulting in the following problems:

[0006] 1. When parts are cut, the contact surface is gradually cut off and becomes thinner and thinner, causing the parts to be thrown out, which can easily cause injuries to related personnel;

[0007] 2. When the parts are cut, the contact surface is gradually cut off and becomes thinner and thinner, causing the contact axis to bend, which in turn causes the cutting tool to break. Even in the best case, problems such as tool jumping may occur, resulting in a reduction in tool life. Summary of the invention

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0051] For example, see Figures 1 to 14 A gear turning, gear grinding and quenching composite machine tool, comprising a machine tool 1 and a No. 1 sliding member 2 fixed on the machine tool 1, a mounting plate 201 being slidably mounted on the No. 1 sliding member 2, a No. 2 sliding member 202 being fixed on the mounting plate 201, a No. 1 direct drive motor 3 being slidably mounted on the No. 2 sliding member 202, a chuck 301 being mounted at one end of the No. 1 direct drive motor 3, and a workpiece being clamped and fixed by the chuck 301;

[0052] A lifting platform, a lifting plate 402 is slidably mounted on one side of the lifting platform, a second direct drive motor 4 is fixed on the lifting plate 402, a processing knife 401 is coaxially fixed on the output shaft of the second direct drive motor 4, a tool reinforcement 403 is also provided on the lifting plate 402, and the tool reinforcement 403 is rotatably connected to the other end of the processing knife 401, and further includes:

[0053] A second support seat 8, the second support seat 8 is fixed on the machine tool 1, a secondary processing mechanism is installed on the second support seat 8, and an iron chip collecting mechanism is installed on the side of the second support seat 8 facing the mounting plate 201, through which the iron chips generated by the processing knife 401 during processing are collected;

[0054] A conveying platform 701 is provided at a side end of the machine tool 1 . The conveying platform 701 cooperates with the secondary processing mechanism. A collecting component 702 cooperating with the conveying platform 701 is installed on one side of the machine tool 1 .

[0055] In the embodiment of the present invention, the metal parts used for processing in the present invention are defined as material parts;

[0056] The material passes through the first direct drive motor 3 and the chuck 301, the material is fixed by the chuck 301, and the first direct drive motor 3 drives the chuck 301 to rotate, thereby driving the chuck 301 and the material to rotate, so as to realize the self-rotation requirement of the material during the processing;

[0057] The mounting plate 201 is driven to move toward or away from the second support seat 8 by the first sliding member 2, and the first direct drive motor 3 and the chuck 301 and the workpiece are driven to move parallel to each other by the second sliding member 202, so as to realize the movement of the workpiece on the machine tool 1 through this movement process. The movement of the workpiece described later is realized according to the above-mentioned movement state;

[0058] When the second direct drive motor 4 rotates, the processing knife 401 is driven to rotate through the conveying shaft, and the material is moved to the side of the processing knife 401 through the above movement, and the material is processed by the rotation of the processing knife 401, and the iron chips generated by the material will be collected by the iron chip collection mechanism to prevent the splashing of iron chips from interfering with the normal operation of other parts;

[0059] The processing knife 401 includes a hob and a gear grinding wheel, which are coaxially fixed. The lifting platform drives the lifting plate 402, the second direct drive motor 4 and the processing knife 401 to move upright, and drives the position switching of the hob and the gear grinding wheel of the processing knife 401, so that the material can complete two processing steps in one position without large-scale movement. After the two processing steps of the material are completed by the processing knife 401, the material moves to the position of the secondary processing mechanism for secondary processing. After the processing is completed, the material is cut and falls into the discharge pipe 7. Under the guidance of the discharge pipe 7, it moves to the conveying platform 701, and is transported to the collecting part 702 by the conveying platform 701 for storage. The conveying platform 701 relies on the conveyor belt inside it to realize the material conveying toward the collecting part 702.

[0060] In summary, the present invention realizes various processing of the material through the above-mentioned motion state, and the processing steps are relatively simple, and the iron filings generated in the processing are collected.

[0061] The iron filings collection mechanism includes a support plate 6 fixed to the second support seat 8 facing the mounting plate 201, two conveying rollers 408 are rotatably mounted on the support plate 6, and the two conveying rollers 408 are connected by a conveyor belt 406. A separation and collection component is provided at the conveying tail end of the conveyor belt 406, and the separation and collection component is fixed to the support plate 6;

[0062] One of the conveying rollers 408 is connected to a driving member mounted on the support plate 6, and the conveying belt 406 is also matched with an iron chip guide assembly mounted on the second support seat 8 and the support plate 6;

[0063] Among them, a side guard 407 is fixed on the side of the conveyor belt 406 away from the second support seat 8, and the side guard 407 and the conveyor belt 406 are both sandwich settings. The conveyor belt 406 and the side guard 407 both include a middle magnetic layer, and wear-resistant layers are fixed on both sides of the magnetic layer.

[0064] In the embodiment of the present invention, when the driving member is working, one of the conveying rollers 408 is driven to rotate, and when the conveying roller 408 rotates, the conveying belt 406 is driven to convey;

[0065] When the chip guide assembly is working, the chip is limited during processing and driven to move to the conveyor belt 406 for conveying. When the chip is conveyed to the conveying end of the conveyor belt 406, the chip is separated from the conveyor belt 406 by the separation and collection assembly and the chip is collected.

[0066] The above description achieves the goal of collecting the flying iron chips and storing them in a designated location.

[0067] The driving member includes a high-torque motor 9 fixed on the support plate 6 , the output shaft of the high-torque motor 9 passes through the support plate 6 , and the output shaft of the high-torque motor 9 is connected to one of the conveying rollers 408 via a No. 1 conveying chain 901 .

[0068] In the embodiment of the present invention, the two conveying rollers 408 are also connected by a No. 2 conveying chain 902. Since there is a certain resistance in the No. 2 direct drive motor 4 when the iron chips are separated and collected, in order to avoid insufficient friction between the conveying belt 406 and the conveying roller 408, the No. 2 conveying chain 902 can realize synchronous and unidirectional rotation of the two conveying rollers 408, so as to greatly reduce the possibility of insufficient friction.

[0069] When the high torque motor 9 is working, its output shaft drives one of the conveying rollers 408 to rotate through the No. 1 conveying chain 901;

[0070] The high-torque motor 9 in the present invention is a high-torque reduction motor, and the present invention does not specifically limit its specific model.

[0071] The separation and collection assembly includes a collection box 409, which is fixed on the support plate 6 and located at the conveying tail end of the conveyor belt 406;

[0072] The top of the collecting box 409 is provided with an inclined surface, the inclined surface abuts against the conveyor belt 406 , a chip feed port 4010 is provided on the inclined surface, and a stop bar 4011 is provided on one side of the chip feed port 4010 .

[0073] In an embodiment of the present invention, the conveyor belt 406 will absorb the iron filings and carry them toward the collection box 409. When the iron filings come into contact with the inclined surface of the collection box 409, the iron filings are shoveled off by the inclined surface and fall into the collection box 409 through the chip feed port 4010, and the stop bar 4011 can block and correct the iron filings to prevent them from falling outside the chip feed port 4010. The iron filings that fall into the collection box 409 will be stored in the collection box 409, and the stored iron filings can be taken out by dismantling the collection box 409 and dumping it.

[0074] The secondary processing mechanism includes an adjustment plate fixed on the second support seat 8, a clamping jaw 801 is fixed on the second support seat 8, and an electromagnetic heating element 501 is provided on the side of the clamping jaw 801 facing the processing knife 401, and the electromagnetic heating element 501 is fixed on the first support seat 5;

[0075] A cutting knife 7010 is fixed to the side end of the second support seat 8 away from the processing knife 401;

[0076] A discharge pipe 7 is fixed to one side of the No. 2 support seat 8, and the discharge port of the discharge pipe 7 faces the conveying platform 701. A material blocking box 709 is fixed to the discharge pipe 7. The material blocking box 709 is sleeved on the cutting knife 7010. A material inlet 703 is opened on the material blocking box 709, and a stabilizing component is installed on the side of the discharge pipe 7 away from the material inlet 703.

[0077] In the embodiment of the present invention, a tool and a rotary head required for processing are installed between the clamping jaw 801 and the cutting tool 7010. The tool rotary head installed is a certain tool rotary head, which is not specifically limited in the present invention and can be selected according to actual operation;

[0078] The function of the electromagnetic heating element 501 is to drive the material to move into the electromagnetic heating element 501 after the material is processed into the desired shape, and to heat the material when the electromagnetic heating element 501 is working. After the heating process is completed, the material is cooled by the matching nozzle, which is a common quenching process in metal processing.

[0079] Secondly, the tool and rotation between the cutting tool 7010 and the clamping jaw 801 are used to process the material into a specified shape. The cutting tool 7010 is used to cut off the tool that has been processed, so that the processed material falls into the blocking box 709, and the processed material is limited by the blocking box 709, and falls onto the conveying table 701 under the guidance of the discharge pipe 7;

[0080] A certain length of material will be stored in the chuck 301 and the No. 1 direct-drive motor 3, and the material will extend out of the chuck 301 by 3-5 cm. After this section is processed and cut off, the chuck 301 will release the material, and then the jaws 801 will clamp and limit the material outside the chuck 301, and then the No. 1 direct-drive motor 3 and the chuck 301 will move in the opposite direction away from the jaws 801 to complete the supply of the material. In simple terms, the material stored in the chuck 301 and the No. 1 direct-drive motor 3 is pulled out.

[0081] A fan 502 is also fixed on the No. 1 support seat 5 , and a discharge member 503 connected to the fan 502 is disposed on one side thereof, and a discharge end of the discharge member 503 faces the processing knife 401 .

[0082] In an embodiment of the present invention, when the fan 502 is working, a certain amount of airflow will be generated, which will be blown toward the processing knife 401 through the guidance of the fan 502, so as to blow the iron chips generated when the processing knife 401 processes the material toward the conveyor belt 406. In the process of the airflow blowing the iron chips, the baffle 405 is used to limit the position, so that the iron chips move to the conveyor belt 406.

[0083] The iron chip guide assembly includes a baffle 405 fixed on the support plate 6 , a blocking plate 404 is arranged at the center of the baffle 405 , and the blocking plate 404 cooperates with the baffle 405 .

[0084] In an embodiment of the present invention, the above-mentioned processing tool 401 of the present invention includes a hob and a gear grinding wheel, with the gear grinding wheel at the top and the hob at the bottom. The diameter of the hob is smaller than that of the gear grinding wheel, so that iron chips will not fall due to the grooves on the baffle 405 when processing through the gear grinding wheel. However, due to the small diameter of the hob, iron chips will fall through the grooves on the baffle 405 when processing through the hob. The above-mentioned problem can be effectively solved by using the sealing plate 404, and the structure is relatively simple.

[0085] The stabilizing component includes a travel limit groove 708 provided on a side of the material blocking box 709 away from the material entry port 703, and a slide seat 707 is slidably installed in the travel limit groove 708;

[0086] A positioning shaft 704 is slidably mounted on the slide seat 707, a limiting ring 705 is coaxially fixed on the positioning shaft 704, and a No. 1 spring 706 is sleeved on the positioning shaft 704, and the No. 1 spring 706 is embedded in a spring slot 7014 provided on the slide seat 707;

[0087] An elastic member is installed on the side of the conveying platform 701 away from the material inlet 703, and the elastic member is connected to the slide seat 707;

[0088] A locking member is installed at the end of the sliding stroke of the sliding seat 707 , and the locking member is matched with the positioning shaft 704 .

[0089] In the embodiment of the present invention, after the material is processed into the specified shape, it enters the final cutting and separation step, firstly driving the material through the material inlet 703 into the material blocking box 709, during which the central axis of the material is provided with an axial hole, which is in a coaxial state with the material inlet 703;

[0090] After the material enters the material blocking box 709, the material moves toward the positioning shaft 704, and the axial hole of the material is sleeved on the positioning shaft 704. As the material moves axially toward the positioning shaft 704, the material abuts against the limiting ring 705, and then the limiting ring 705 drives the positioning shaft 704 and the positioning shaft 704 to follow the movement. In the process, the No. 1 spring 706 is also compressed, so that the No. 1 spring 706 reserves a certain amount of elastic potential energy.

[0091] After the positioning shaft 704 and the limiting ring 705 are pushed to the end of the stroke by the material, the required cutting position of the material is perpendicular to the cutting blade 7010. The material is cut by the cutting blade 7010 through the movement of the material toward the cutting blade 7010. At the moment when the material is cut, the chuck 301 needs to move in the direction away from the positioning shaft 704 to complete the cutting of the material. In this process, since the material is sleeved on the positioning shaft 704, the material is limited by the positioning shaft 704, thereby giving stability to the cut section of the material, so that the material will not be thrown out due to the thinning of the connection point between the two sections of the material, and because the material is limited, the material will not bend during the cutting process due to the thinning of the connection point between the two sections of the material. The problem caused by the bending is the damage of the tool, and the corresponding "jumping tool" problem is also effectively solved.

[0092] After the two ends of the materials are cut and separated, the elastic component and the locking component work together to drive the slide 707 and the No. 1 spring 706 to reset. During the reset process, the positioning shaft 704 will release the elastic potential energy stored in the No. 1 spring 706 after a certain distance of reciprocating movement, so as to prevent the elastic potential energy of the material from being released instantly after cutting, causing the material to be quickly ejected and hit by the cutting knife 7010.

[0093] After the positioning shaft 704 moves back and forth for a certain distance, the elastic potential energy stored in the No. 1 spring 706 is released to drive the limit ring 705 and the positioning shaft 704 to rebound quickly, thereby driving the cut material to follow the movement. When the cut material moves, a certain inertia will be generated, and the inertia will be used to separate the material from the positioning shaft 704 and fall into the material blocking box 709 and the discharge pipe 7.

[0094] The elastic member includes a guide rod 7011 fixed on the material blocking box 709 , the guide rod 7011 is slidably matched with the slide seat 707 , and a No. 2 spring 7012 is sleeved on the guide rod 7011 .

[0095] In the embodiment of the present invention, when the slide 707 moves, the second spring 7012 is gradually compressed, so that the second spring 7012 reserves elastic potential energy. When the material on the positioning shaft 704 is cut off, the cut material is separated from the limit of the material on the chuck 301. At the moment of separation, the cut material is in a natural state without limit and constraint. Therefore, the elastic potential energy of the second spring 7012 is released instantly, thereby driving the slide 707, the positioning shaft 704, and the material to move back and forth until the end of the stroke.

[0096] It should be noted that the slide seat 707 performs damping and shock absorption when sliding.

[0097] The locking member includes at least one limiting strip 7016 fixed on the positioning shaft 704, and the limiting strip 7016 is slidably matched with a limiting groove 7017 provided on the slide seat 707, and the rotation of the positioning shaft 704 is limited by the cooperation between the limiting groove 7017 and the limiting strip 7016;
