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.

[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

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, which can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0051] Example 1, please refer to Figures 1 to 14 , a combined hobbing, grinding and quenching machine tool for vehicles, including a machine tool 1 and a first sliding member 2 fixed on the machine tool 1. An installation plate 201 is slidably installed on the first sliding member 2. A second sliding member 202 is fixed on the installation plate 201. A first direct drive motor 3 is slidably installed on the second sliding member 202. A chuck 301 is installed at one end of the first direct drive motor 3. The workpiece is clamped and fixed by the chuck 301;

[0052] A lifting table. A lifting plate 402 is slidably installed on one side of the lifting table. A second direct drive motor 4 is fixed on the lifting plate 402. A processing tool 401 is coaxially fixed on the output shaft of the second direct drive motor 4. There is also a tool reinforcement member 403 on the lifting plate 402. The tool reinforcement member 403 is rotatably connected to the other end of the processing tool 401. It further includes:

[0053] A second support seat 8, which is fixed on the machine tool 1. A secondary processing mechanism is installed on the second support seat 8. A chip collection mechanism is installed on the side of the second support seat 8 facing the installation plate 201. The chips generated during the processing of the processing tool 401 are collected by the chip collection mechanism;

[0054] A conveying table 701, which is located at the side end of the machine tool 1. The conveying table 701 cooperates with the secondary processing mechanism. A collection member 702 that cooperates with the conveying table 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 are defined as workpieces;

[0056] The workpiece passes through the first direct drive motor 3 and the chuck 301. The workpiece is fixed by the chuck 301. The first direct drive motor 3 is driven to rotate the chuck 301 to drive the chuck 301 and the workpiece to rotate, so as to meet the self-rotation requirement of the workpiece during the processing;

[0057] The first sliding member 2 is driven to move the installation plate 201 towards or away from the second support seat 8. The second sliding member 202 is driven to move the first direct drive motor 3, the chuck 301 and the workpiece in parallel, so as to move the workpiece on the machine tool 1 through this movement process. The subsequent description of the movement of the workpiece is realized based on the above movement state;

[0058] When the second direct drive motor 4 rotates, the processing tool 401 is driven to rotate through the transmission shaft. Through the above movement, the workpiece is moved to one side of the processing tool 401 and the workpiece is processed by the rotation of the processing tool 401. The chips generated by the workpiece will be collected by the chip collection mechanism to prevent the chips from splashing and interfering with the normal operation of other components;

[0059] The processing tool 401 includes a hob and a gear grinding wheel, which are coaxially fixed to each other. The lifting table drives the lifting plate 402, the second direct drive motor 4, and the processing tool 401 to move vertically, driving the position switching of the hob and the gear grinding wheel of the processing tool 401, so as to realize that two processing steps can be completed for the workpiece without large-scale movement at one position. After the two processing operations of the workpiece are completed by the processing tool 401, the workpiece moves to the position where the secondary processing mechanism is located for secondary processing. After the processing is completed, the workpiece is cut and dropped into the discharge pipe 7. Under the guidance of the discharge pipe 7, it moves into the conveying table 701 and is conveyed to the collecting member 702 for storage through the conveying table 701. The conveying table 701 realizes the conveyance of the workpiece towards the collecting member 702 by means of the conveyor belt inside it;

[0060] In summary, the present invention realizes various processing operations on the workpiece through the above-mentioned motion states, and the processing steps are relatively simple, and the iron filings generated during the processing are collected.

[0061] The iron filing collecting mechanism includes a support plate 6 fixed to the side of the second support base 8 facing the mounting plate 201. Two conveying rollers 408 are rotatably mounted on the support plate 6. A conveyor belt 406 is connected between the two conveying rollers 408. A separation and collection assembly is provided at the conveying end of the conveyor belt 406, and the separation and collection assembly 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 conveyor belt 406 also cooperates with an iron filing guiding assembly mounted on the second support base 8 and the support plate 6;

[0063] Wherein, a retaining edge 407 is fixed to the side of the conveyor belt 406 away from the second support base 8. The retaining edge 407 and the conveyor belt 406 are both arranged in layers. The conveyor belt 406 and the retaining edge 407 both include a magnetic layer in the middle, 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 works, it drives one of the conveying rollers 408 to rotate, and when the conveying roller 408 rotates, it drives the conveyor belt 406 to convey;

[0065] When the iron filing guiding assembly works, it limits the iron filings during processing and drives the iron filings to move onto the conveyor belt 406 for conveyance. When the iron filings are conveyed to the conveying end of the conveyor belt 406, the separation and collection assembly separates the iron filings from the conveyor belt 406 and collects the iron filings;

[0066] Through the above description, the splashing iron filings are collected and stored at a designated position.

[0067] The driving member includes a high-torque motor 9 fixed to the support plate 6. The output shaft of the high-torque motor 9 penetrates the support plate 6, and the output shaft of the high-torque motor 9 is connected to one of the conveying rollers 408 through a first conveying chain 901.

[0068] In the embodiment of the present invention, the two conveying rollers 408 are also connected by a second conveying chain 902. Since there is a certain resistance for the second direct-drive motor 4 during iron chip separation and collection, in order to avoid insufficient friction between the conveyor belt 406 and the conveying rollers 408, the second conveying chain 902 can be used to achieve synchronous and co-directional rotation of the two conveying rollers 408, so as to greatly reduce the possibility of insufficient friction.

[0069] When the high-torque motor 9 works, its output shaft drives one of the conveying rollers 408 to rotate through the first conveying chain 901.

[0070] Among them, the high-torque motor 9 in the present invention is a high-torque reduction motor, and its specific model is not specifically limited in the present invention.

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

[0072] The top of the collection box 409 is provided with an inclined surface, the inclined surface abuts against the conveyor belt 406, a chip inlet 4010 is provided on the inclined surface, and a baffle 4011 is provided on one side of the chip inlet 4010.

[0073] In the embodiment of the present invention, when the conveyor belt 406 conveys, it will adsorb iron chips and carry the iron chips towards the collection box 409. When the iron chips contact the inclined surface of the collection box 409, the iron chips are shoveled off by the inclined surface and fall into the collection box 409 through the chip inlet 4010, and the baffle 4011 can play a role in blocking and correcting the iron chips to prevent the iron chips from falling to positions other than the chip inlet 4010. The iron chips falling into the collection box 409 will be stored through the collection box 409, and the stored iron chips can be taken out by removing the collection box 409 and pouring it.

[0074] The secondary processing mechanism includes an adjustment plate fixed to the second support base 8. A clamping jaw 801 is fixed to the second support base 8. An electromagnetic heating element 501 is provided on the side of the clamping jaw 801 facing the processing tool 401, and the electromagnetic heating element 501 is fixed to the first support base 5.

[0075] A cutting tool 7010 is fixed to the side end of the second support base 8 away from the processing tool 401.

[0076] On one side of the second support base 8, a discharge pipe 7 is fixed. The discharge port of the discharge pipe 7 faces the conveying table 701. A material blocking box 709 is fixed on the discharge pipe 7. The material blocking box 709 is sleeved on the cutting tool 7010. A material piece inlet 703 is provided on the material blocking box 709. A stabilizing component is installed on the side of the discharge pipe 7 away from the material piece inlet 703.

[0077] In an embodiment of the present invention, a tool and a rotating head required for processing are installed between the clamping jaws 801 and the cutting tool 7010. Specifically, a certain type of tool rotating head is installed. The present invention does not make specific limitations and can be selected according to actual operations.

[0078] The function of the electromagnetic heating element 501 is that after the material piece is processed into the required shape, it will drive the material to move into the electromagnetic heating element 501. When the electromagnetic heating element 501 works, the material piece is heated. After this heating process is completed, it is cooled through a supporting nozzle, that is, the common quenching treatment in metal processing.

[0079] Secondly, the tool and rotation between the cutting tool 7010 and the clamping jaws 801 are used to process the material piece into the specified shape. The cutting tool 7010 is used to cut off the completed tool, so that the processed material piece falls into the material blocking box 709. The material blocking box 709 limits the processed material piece, and under the guidance of the discharge pipe 7, it falls onto the conveying table 701.

[0080] A certain length of material piece is stored in the chuck 301 and the first direct drive motor 3. The material piece extends 3 - 5 cm outside the chuck 301. After this section is processed and cut off, the clamping of the material piece by the chuck 301 is released. Then, the clamping jaws 801 clamp and limit the material piece outside the chuck 301. Then, the first direct drive motor 3 and the chuck 301 move in the direction away from the clamping jaws 801, and the supply of the material piece can be completed. Simply put, it is to pull out the material piece stored in the chuck 301 and the first direct drive motor 3.

[0081] A blower 502 is also fixed on the first support base 5. A discharge component 503 communicated with it is arranged on one side of the blower 502. The discharge end of the discharge component 503 faces the processing tool 401.

[0082] In an embodiment of the present invention, when the blower 502 works, a certain amount of air flow is generated. It is blown towards the processing tool 401 through the guidance of the blower 502 to blow the iron filings generated when the processing tool 401 processes the material piece towards the conveyor belt 406. During the process of the air flow blowing the iron filings, it is limited by the baffle 405, so that the iron filings move onto the conveyor belt 406.

[0083] The iron filings diversion assembly includes a baffle 405 fixed to the support plate 6. A sealing plate 404 is provided at the center of the baffle 405, and the sealing 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. The gear grinding wheel is above, and the hob is below. The diameter of the hob is smaller than that of the gear grinding wheel. Thus, when processing with the gear grinding wheel, the iron filings will not fall due to the notch on the baffle 405. However, due to the small diameter of the hob, when processing with the hob, the iron filings will fall through the notch on the baffle 405. And the above problems can be effectively solved by the sealing plate 404, and the structure is relatively simple.

[0085] The stable assembly includes a stroke limit groove 708 opened on one side of the material retaining box 709 away from the material inlet 703. A sliding seat 707 is slidably installed in the stroke limit groove 708;

[0086] A positioning shaft 704 is slidably installed on the sliding seat 707. A limit ring 705 is coaxially fixed on the positioning shaft 704. And a first spring 706 is also sleeved on the positioning shaft 704, and the first spring 706 is embedded in a spring slot 7014 opened on the sliding seat 707;

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

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

[0089] In an embodiment of the present invention, when the workpiece is processed into a specified shape and enters the final cutting and separating step, first, the workpiece is driven to enter the inside of the material retaining box 709 through the material inlet 703. During this process, a shaft hole is opened in the central axis of the workpiece, and the shaft hole is in a coaxial state with the material inlet 703;

[0090] After the workpiece enters the material retaining box 709, the workpiece moves towards the positioning shaft 704, and the shaft hole of the workpiece is sleeved on the positioning shaft 704. As the workpiece moves axially towards the positioning shaft 704, the workpiece abuts against the limit ring 705, and then drives the positioning shaft 704 and the positioning shaft 704 to move accordingly through the limit ring 705. And during this process, the first spring 706 is also compressed, so that the first spring 706 stores 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 to the positioning shaft 704. The limiting strip 7016 is slidably engaged with a limiting groove 7017 formed in the sliding seat 707. The rotation of the positioning shaft 704 is limited by the cooperation of the limiting groove 7017 and the limiting strip 7016.

[0098] A pin hole 7015 is formed in the positioning shaft 704. A pin shaft 7013 is fixed at the end of the stroke of the sliding seat 707 on the material retaining box 709. The pin shaft 7013 is inserted into the pin hole 7015.

[0099] In the embodiment of the present invention, when the sliding seat 707 and the positioning shaft 704 move to the end of the stroke, the pin shaft 7013 is inserted into the pin hole 7015.
