[0003] A range stop cylinder, referring to Figure 1 , comprises a cylindrical cylinder body 11 and four edge pipes 12 fixed to the side wall of the cylinder body 11, the four edge pipes 12 are arranged in a cylindrical shape, the four edge pipes 12 are axially parallel to the axial direction of the cylinder body 11, and the four edge pipes 12 are distributed along the circumferential direction of the side wall of the cylindrical cylinder body 11 at equal intervals; a semispherical shaft penetrating part 13 is fixed to one end of the cylinder body 11, the shaft penetrating part 13 is fixed to the center part of the one end of the cylinder body 11, the top end of the shaft penetrating part 13 is ground flat, a through hole 16 is formed in the top end of the shaft penetrating part 13 and penetrates the shaft penetrating part 13 along the axial direction of the cylinder body 11; an arc-shaped plate 14 parallel to the axial direction of the cylinder body 11 is fixed to the one end of the cylinder body 11 close to the shaft penetrating part 13, the arc-shaped plate 14 is arranged close to the shaft penetrating part 13, and the plate surface of the arc-shaped plate 14 is arranged in a curved shape and is attached to the edge of the shaft penetrating part 13; a hollow pin is fixed to the one end of the cylinder body 11 close to the shaft penetrating part 13 and close to one side edge, and the axial direction of the hollow pin is parallel to the axial direction of the edge pipe 12.

[0004] The range stop cylinder is formed to a cylinder body, and a cylinder groove needs to be formed in the cylinder body to accommodate a shift ring, a shift screw piece and other shift components on a shift lever. Figure 2 Referring to , a cylinder groove 17 is formed in the cylinder body, and the cylinder groove 17 is communicated with the shaft penetrating hole; after the cylinder groove 17 is formed, the cylinder body 11 is in a cylindrical shape as a whole, the one end of the cylinder body 11 close to the arc-shaped plate 14 is closed, and the other end of the cylinder body 11 is open.

[0005] The reaming process of the cylinder groove in the range stop cylinder needs two continuous processes of turning and polishing, in order to save the processing time of a single workpiece and improve the workpiece processing efficiency, a turning and polishing integrated numerical control machine tool is generally used to process the range stop cylinder in the actual process, and the numerical control machine tool switches the tool after turning and then performs the polishing process.

[0006] But at present, due to the special shape of the workpiece of the range stop cylinder, it is generally installed on the numerical control machine tool manually by workers and positioned, and the manual positioning method needs workers to adjust the installation position repeatedly according to visual observation when a single workpiece is installed, and in some manufacturing workshops of large and medium-sized enterprises, the method of fixing the range stop cylinder by using an electric three-jaw chuck is adopted, but the electric three-jaw chuck is expensive, the maintenance cost is high, and a high energy consumption is required for supporting in work, and it is not suitable for small enterprises.

[0007] For the related technologies in the above, the inventors believe that the positioning mechanism of the existing turning and grinding integrated numerical control machine tool can be improved, so as to improve the automation degree in low-cost technology, optimize the traditional worker feeding process, and improve the feeding and positioning efficiency of a single workpiece. SUMMARY

[0008] In order to optimize the feeding process of the numerical control machine tool and improve the positioning and feeding efficiency of a single workpiece, the application provides a feeding device for a range stop cylinder turning and grinding integrated machine tool.

[0009] The feeding device for the range stop cylinder turning and grinding integrated machine tool provided by the application adopts the following technical scheme:

[0010] A feeding device for a range stop cylinder turning and grinding integrated machine tool, comprising a rotary table axially and horizontally installed on the inner side wall of the machine warehouse of a numerical control machine tool, a positioning mechanism, a fixing mechanism and a pop-up mechanism of the range stop cylinder are arranged on the rotary table, the rotary table is corresponding to the turning tool of the numerical control machine tool, and the feeding device further comprises:

[0011] A material conveying table is arranged in the machine warehouse, the material conveying table is inclined, one side edge of the inclined upward material conveying table is hinged to the inner side wall of the machine warehouse, the height of the hinge point of the two is not higher than the lowest point of the rotary table, and a rotary driving piece for driving the rotary table to rotate is arranged on the inner wall of the machine warehouse;

[0012] A material collecting groove is slidably arranged in the material conveying table, one end of the material collecting groove can slide to the outside of the downward inclined end of the material conveying table, and a sliding driving piece for sliding the material collecting groove is arranged in the material conveying table;

[0013] An inclined feeding plate is arranged on the material conveying table, one end of the inclined upward feeding plate is hinged to the material conveying table, the feeding plate and the material conveying table are slidably connected, and a driving piece for driving the feeding plate to rotate and slide is arranged on the material conveying table;

[0014] A groove is arranged on the feeding plate, the groove is corresponding to the shape of the cylinder body of the range stop cylinder and is used for fixing the range stop cylinder in the conveying process;

[0015] A material pushing mechanism is arranged on one side of the material conveying table and is used for pushing the range stop cylinder to the rotary table for fixation.

[0016] By adopting the technical scheme, the rotary table is a specific bearing part of the range blocking cylinder, and the positioning mechanism and the fixing mechanism arranged on the rotary table realize stable installation of the range blocking cylinder during turning and polishing of the range blocking cylinder. The machining process of turning and polishing of the range blocking cylinder needs the motor of the numerical control machine tool to drive the rotary table to rotate at high speed. The structure of the rotary table and the driving motor determines that the rotary table cannot change the angle in the horizontal plane by using hinging to facilitate workers to load. If not improved, the workers can only manually install the workpiece by putting their hands into the machine compartment of the numerical control machine tool. Considering the limitation of structural improvement, the scheme starts from the internal structure of the machine compartment of the numerical control machine tool. An inclined material conveying table is arranged on the inner wall of the machine compartment, and a loading plate is arranged on the material conveying table. The material conveying table and the loading plate are driven by driving members through the connection mode of respective hinged rotation and sliding. The automatic loading of the range blocking cylinder is realized. The loading process is as follows. The worker opens the door plate of the machine compartment of the numerical control machine tool, and then controls the numerical control machine tool to drive the loading plate to rotate relative to the material conveying table until the loading plate is in a horizontal state. At the same time, the driving member drives the loading plate to slide towards the side of the material conveying table which is inclined downward. When one end of the loading plate slides out of the machine compartment of the numerical control machine tool, the worker installs the range blocking cylinder into the mold groove. Then, the driving member drives the loading plate to return to the initial state. The driving member drives the material conveying table to become horizontal, and the driving member drives the loading plate to fall. The inclination speed of the material conveying table and the reverse inclination speed of the loading plate are kept the same, that is, the loading plate keeps the horizontal state during the rotation of the material conveying table and the loading plate and finally adheres to the material conveying table. Finally, the pushing mechanism on one side of the material conveying table pushes the range blocking cylinder towards the rotary table until the range blocking cylinder is on the positioning mechanism and the fixing mechanism of the rotary table. The material conveying table drives the loading plate to return to the initial state. When unloading, the ejecting mechanism on the rotary table ejects the range blocking cylinder into the material collecting groove. The door plate of the numerical control machine tool is opened. The sliding driving member operates to slide the material collecting groove towards the material conveying table until the material collecting groove slides out of the door plate. The worker can grab the range blocking cylinder from the material collecting groove.

[0017] Optionally, the pushing mechanism comprises;

[0018] The pushing cylinder is horizontally arranged on the side of the material conveying table away from the rotary table. The cylinder body of the pushing cylinder is fixedly connected to the edge of the material conveying table away from the rotary table.

[0019] The pushing plate is arranged on the end of the piston rod of the pushing cylinder.

[0020] By adopting the technical scheme, the pushing plate is an auxiliary mechanism of the pushing cylinder. The pushing cylinder is used to drive the range blocking cylinder to displace along the axis of the rotary table. When the loading plate keeps horizontal and transports the range blocking cylinder clamped in the mold groove to the same height of the rotary table, the pushing cylinder extends the piston rod to drive the pushing plate to push the range blocking cylinder towards the rotary table, and then the range blocking cylinder is clamped by the positioning mechanism and the fixing mechanism on the rotary table.

[0021] Optionally, a chip removal groove is formed in the side wall of the side of the material collecting groove which is inclined downward.

[0022] By adopting the above technical scheme, since the turning tool needs to extend into the cylinder groove of the range stop cylinder during the turning and polishing process, a small amount of iron filings is left in the cylinder groove after the machining is completed, and the iron filings falls into the receiving groove when the range stop cylinder is ejected into the receiving groove by the ejection mechanism, so the setting of the chip groove is beneficial to the timely discharge of the iron filings, thereby avoiding the accumulation of the iron filings in the receiving groove and affecting the subsequent conveying of the range stop cylinder.

[0023] Optionally, the rotating member comprises;

[0024] The rotating rods are arranged in parallel below the feeding plate and are accommodated on the material conveying table and can be rotated to be perpendicular to the table top of the material conveying table.

[0025] The rotating motor is arranged on the material conveying table corresponding to the rotating rods, and the output shaft of the rotating motor is fixed to the same end of the rotating rods.

[0026] By adopting the above technical scheme, the feeding plate is lifted by the basic physical rotating structure, in the initial state, the rotating rod is arranged in parallel between the feeding plate and the material conveying table, when the material conveying table is required to be horizontal, the rotating rod is first driven to rotate by the rotating motor, the end of the rotating rod away from the rotating motor abuts against and supports the feeding plate, and the inclination angle of the feeding plate is increased with the sliding of the hinge point of the feeding plate, so that the feeding plate is continuously kept in a horizontal state; it is additionally mentioned that the selection of the rotating motor realizes the controllability and stability of the motor on the basis of low cost, and it is suggested to select a stepping motor, which has the advantages of high torque output, can maintain high stability of the feeding plate in the low speed and static state, and has simple structure and low maintenance cost.

[0027] Optionally, the positioning mechanism comprises;

[0028] The annular groove is arranged on the side of the rotating table close to the feeding plate, and the annular groove is arranged corresponding to the arc-shaped plate of the range stop cylinder.

[0029] The semispherical groove is arranged corresponding to the shaft penetrating member of the range stop cylinder, and the position relationship between the semispherical groove and the annular groove corresponds to the position relationship between the shaft penetrating member and the arc-shaped plate of the range stop cylinder.

[0030] By adopting the above technical scheme, the annular groove and the semispherical groove are the main components for positioning, during the rotation of the rotating table, the six degrees of freedom of the range stop cylinder need to be completely constrained in the spherical coordinate system of the fixed end of the rotating table, the worker places the range stop cylinder according to the corresponding position during installation, so that the arc-shaped plate of the range stop cylinder can be directly pushed into the annular groove for clamping when the material pushing cylinder operates, and the shaft penetrating member of the range stop cylinder can be clamped in the semispherical groove, and the constraint on the degrees of freedom is increased by positioning and clamping.

[0031] Optionally, the positioning mechanism further comprises;

[0032] The edge column is provided with a plurality of edge columns, and each edge column corresponds to each through hole on the range blocking air cylinder.

[0033] By adopting the above technical scheme, the two degrees of freedom of the range blocking air cylinder are constrained by the scheme of the ring groove clamping the arc plate and the hemispherical groove clamping the through shaft piece. On this basis, a plurality of edge columns are inserted into the through holes of the range blocking air cylinder. When the range blocking air cylinder is pushed by the pushing air cylinder, the four edge pipes of the range blocking air cylinder correspond to the edge columns, and the four edge columns are clamped into the through holes, thereby forming full constraint on the three rotational degrees of freedom of the range blocking air cylinder, reducing the six overall degrees of freedom to one degree of freedom along the axis of the rotary table, and increasing the constraint effect on the range blocking air cylinder.

[0034] Optionally, the fixing mechanism comprises;

[0035] The corner air cylinder is provided with a plurality of corner air cylinders, and the corner air cylinders are arranged on the side of the rotary table close to the feeding plate. The cylinder body of the corner air cylinder is arranged parallel to the axis of the rotary table, and the corner air cylinder corresponds to the edge pipe.

[0036] The pressing block is fixed to the end of the rotating rod of the corner air cylinder, and one end of the pressing block can be displaced to the end of the edge pipe of the range blocking air cylinder with the operation of the corner air cylinder.

[0037] By adopting the above technical scheme, the assembly mode of the corner air cylinder and the fixing pin is similar to the assembly mode of the pushing air cylinder and the pushing plate. When the range blocking air cylinder is pushed onto the rotary table by the pushing plate, the rotating rod of the corner air cylinder rotates and drives the pressing block to rotate and abut against the end of the edge pipe. The piston rod of the corner air cylinder is retracted, and the pressing block presses the edge pipe of the range blocking air cylinder. In this way, the last constraint degree of the range blocking air cylinder is limited, and the range blocking air cylinder is prevented from being thrown out along the edge column during the rotation of the rotary table. One corner air cylinder is arranged at each of the two opposite edge pipes.

[0038] Optionally, a plurality of material collecting springs are fixed to the inner wall of the hemispherical groove, and the axial direction of the material collecting spring is parallel to the axial direction of the rotary table. One end of the material collecting spring away from the inner wall of the hemispherical groove is a free end and extends into the hemispherical groove.

[0039] By adopting the above technical scheme, the arrangement of the material collecting spring provides the basis for the range blocking air cylinder to be ejected relative to the rotary table. When the pushing air cylinder pushes the range blocking air cylinder towards the rotary table, the through shaft piece of the range blocking air cylinder is clamped into the ring groove and the hemispherical groove respectively. When the range blocking air cylinder is clamped into the ring groove and the hemispherical groove respectively, the range blocking air cylinder is pressed inwards to press the material collecting spring. After the machining is completed, the corner air cylinder cancels the fixation of the range blocking air cylinder, and the material collecting spring relaxes to eject the range blocking air cylinder from the rotary table, thereby realizing automatic unloading.

[0040] In summary, the present application has the following at least beneficial technical effects:

[0041] 1. The hinged connection between the loading plate and the conveying platform facilitates loading by workers, overcoming the drawback that the turntable's rotating connection mechanism cannot rotate around the vertical axis in the horizontal plane. The loading plate can be flexibly slid out of the machine room through the hinged and sliding mechanisms on the inner wall of the machine room, moving the loading plate to a position that is convenient for workers to place directly. After the workers install the workpiece, the loading plate is retracted. In the entire loading process, the workers only need to align the workpiece with the groove, matching the arc plate of the range-blocking cylinder with the annular groove on the turntable, and the through-shaft part with the hemispherical groove on the turntable.

[0042] 2. The modification cost is low. The energy consumption of the electric three-jaw chuck in the original application is applied to the motor and cylinder of this application, which not only reduces the energy consumption cost of CNC machine tools, but also reduces the maintenance cycle of workers, and applies the downtime of CNC machine tools for maintenance to the processing of workpieces.

[0043] 3. Enhanced restriction on degrees of freedom: Traditional electric three-jaw chucks only hold the outer side of the range stop cylinder with three jaws, relying on friction to restrict the range stop cylinder. This makes the outer side of the range stop cylinder prone to wear due to high-frequency vibration during workpiece processing. Attached Figure Description

[0060] The feeding and positioning process of a single range blocking cylinder 1 is described as follows: the piston rod of the first driving cylinder 221 is extended, the material conveying table 4 is driven to rotate around the hinged edge to change the included angle with the horizontal plane, so that the height of the material collecting groove 49 is not too low after the material collecting groove 49 slides out of the material conveying table 4, and the worker can directly place the range blocking cylinder 1; at the same time that the angle of the material conveying table 4 is changed, the second driving cylinder 43 drives the feeding plate 42 in the material feeding groove 41 to slide along the opening direction of the material feeding groove 41, and the feeding plate 42 is extended to the outside of the numerical control machine tool 2; at the same time that the feeding plate 42 slides along the material feeding groove 41, the output shaft of the rotating motor 46 rotates to drive one end of the rotating rod 45 to rotate and abut against the feeding plate 42, support the feeding plate 42 to rotate around the hinged point to change the angle, and in the displacement process of the feeding plate 42, the rotating motor 46 continuously adjusts the angle, so that the feeding plate 42 is in a horizontal state when it finally slides to the worker, the worker directly places one end of the arc-shaped plate 14 of the range blocking cylinder 1 toward one side of the rotating table 3, the worker finishes feeding, and the feeding plate 42 is retracted to the original position.

[0061] In the process of the second driving cylinder 43 driving the upper feeding plate 42 to retract and reset, the piston rod of the first driving cylinder 221 is retracted at the same time, so that the material conveying table 4 rotates and resets. In the process of the material conveying table 4 rotating and resetting and the upper feeding plate 42 sliding and resetting, the rotating motor 46 operates at the same time with the first driving cylinder 221 and the second driving cylinder 43, continuously and synchronously adjusts the angle of the rotating rod 45, so that the upper feeding plate 42 continuously maintains a horizontal state in the process of the range blocking cylinder 1 being transported to the numerical control machine tool 2, and the upper feeding plate 42 finally transports the range blocking cylinder 1 to the same height as the rotating table 3.

[0062] The pushing cylinder 48 extends the piston rod, pushes the range blocking cylinder 1 towards the rotating table 3 through the pushing plate 481, the arc-shaped plate 14 is inserted into the ring groove 31, the four edge pipes 12 are simultaneously inserted into the edge columns 35, the hollow pin is inserted into the corresponding positioning groove 34, the penetrating shaft 13 abuts against the semispherical groove 32 and extrudes the material collecting spring 33, and then the rotating angle cylinder 36 operates to drive one end of the pressing block 361 to rotate to the end of the edge pipe 12 and press the end of the edge pipe 12.

[0063] After being fixed, the pushing cylinder 48, the material conveying table 4 and the upper feeding plate 42 are reset, so as to avoid the pushing cylinder 48 blocking the feeding of the turning tool 211. The turning tool 211 feeds towards the rotating table 3, the main motor 212 drives the rotating table 3 to rotate, so that the inner wall of the cylinder groove 17 of the rotating range blocking cylinder 1 contacts the turning tool 211, and the turning process is completed. Then the turning tool 211 feeds back, the cutter head 21 rotates, the polishing tool is aligned with the inner wall of the cylinder groove 17 and feeds, and the same polishing process as turning is performed, until the single workpiece is processed.

[0064] Before the processing is completed, the third driving cylinder first operates to push the material collecting groove 49 to slide to the outside of the material conveying table 4 and remain, until the material collecting groove 49 is located below the rotating table 3. Then the rotating angle cylinder 36 drives the pressing block 361 to rotate, instantaneously cancels the pressing of the range blocking cylinder 1, the material collecting spring 33 relaxes, the range blocking cylinder 1 is bounced outwards and falls into the material collecting groove 49 to complete the material collecting, and the range blocking cylinder 1 collides with the bottom of the material collecting groove 49 to discharge the falling debris from the chip removal groove 491, so as to prevent the debris from accumulating in the material collecting groove 49 and affecting the material collecting.

[0065] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
