Description

Machining device capable of chipping and creating grooves and sockets in and out of sight positions

[0001] This invention is related to the mechanical area with a sub-section of machines.

[0002] To date, various methods have been employed to facilitate such processes:

[0003] The first method involves creating a single-purpose production line, which demands substantial investment and costs to make such grooves. It is not cost-effective for productions with less than a million units. The other method is splitting the part into two halves in the groove line, creating an inner groove, welding the cut area, and machining the welded edges, which causes wastage of the parts and inadequate accuracy and has the potential for warping. The final method uses seven-axis machines, versatile fixtures, specialized tools, and inverters to recognize the x-y-z position, step ratio, and the beginning and end of the groove.

[0004] Searching the relevant history in the national and international databases, we didn't find a machine similar to this invention.Technical Problem

[0005] We have to make sockets or grooves in the inner walls of some assembled components so that two or more parts function together. The opposite assembled part acts as a guide or Horizontal guide in the created groove path, working in twisting, step, rail, or angular motions. The thickness, depth, length, and end of the groove path are of utmost importance in these components. Due to the high precision required, casting or die-casting methods are inadequate for creating grooves; instead, we should use high-precision chipping methods with measurement capability. Until now, no machine has been made capable of creating grooves outside of the view or inverted internal sockets (built in the center of the part) within the walls of the parts. Consequently, the industry must develop various tools utilizing multiple machines and complex fixtures, wasting time and money. This waste of resources happens only to produce a single-purpose product and avoids squandering billions of dollars invested in multi-purpose machines.

[0006] The primary objective behind developing this machine is to resolve the abovementioned issues by efficiently implementing necessary processes. First, we want to implement the process and then efficiently facilitate some procedures, including rotational or twisting form, negative angle, internal inverse angles, and horizontal and compound forms. The benefits of this machine include using the available tools and replaceable and repairable mechanical systems, as well as a workforce that requires less training for an operator. Moreover, it is possible to have high-volume production along with similar quality and quantity under control. Simultaneously, it prevents setting up a one-purpose production line. This machine can make negative and internal angles with twisting steps and chipping method concerning length, depth, step, and diameter in a versatile manner.Solution to Problem

[0007] The claimed invention, a "Machining device capable of chipping and creating grooves and sockets in and out of sight positions," is made of the following components:

[0008] Bottom base plate (1), base plate (2), Horizontal guide (3), stop clamp plate (4), bottom clamp (5), upper clamp (6), clamp screw (7), workpiece (8), guide 20 (9), base fixture (10), stop clamp (11), screw installation plate (12), pin and nut plate (13), retainer plate (14), location of four springs (15), lower round bearing (16), lower limit step (17), microswitch (upper limit step) (18), mediating bushing (19), microswitch base (20), workpiece outlet (21), loading screw M20*1mm (22), center start bushing (23), bearing location 42 to 17 (24), mediating plate (25), center connecting rod 75.00 (27), center connecting rod 80.00 (28), connecting rod cap (29), pin plug gauge 15 (30), roller bearing 21 to 15 (31), the upper plate that is located under the gearbox (32), gearbox engine base 1RPM (33), Round bottom bearing 25-47 (34), gearbox engine shaft 200RPM (35), gearbox engine base 200RPM (36), gearbox engine shaft 1RPM (37), screw-engine mediating bushing (38), electric motor body base 200RPM (39), 5PCS grease fitting (40), shaft spacer 30 (41), main base table (42), holder step 40 (43), fixing pins 10 (44), gearbox engine 200RPM (45), engine gearbox 1 (46), bearing connection pin (47), Round bottom bearing 35 to 20 (48), thorn (49), Round bottom bearing 21-35 (50), lock nut (51), spiral nut P40 (52), Round bottom bearing 21-35 (53), Acceleration slip adjustment ring behind the bearing (54), mediating plate spacer with gearbox (55), gearbox 200RPM (56), couple gearbox 1RPM (57), spacer ring (58), and bottom engine plate gearboxes (59).

[0009] The invention operates as follows: 1) circular movement; 2) charging, which determines the amount of material to be removed from the edge of the workpiece by chipping operation that changes the state from rotary to linear, 3) the holder rotates with a variable step in reciprocating motion, 4) it simultaneously creates the groove in width, 5) it simultaneously creates the groove in length using a holder with precise tabs and property of measuring and loading in transverse and longitudinal depth in the workpiece which can make negative internal angles with precise step concerning the diameter, with variable lengths and matching for different parts.

[0010] The current mechanism utilizes a three-tab system, where the holder rotates through a crankshaft mechanism powered by an electric motor, and a reducer gearbox supplies its power. When charging via a screw, the chipping operation is initiated by rotating the holder to the right of the height and the left to the lower part of the height. The power is supplied by an electromotor capable of making two turns to the left and the right; two compound couple reducer gearboxes provide its power. The system uses a three-phase power. The system and mechanism comprise alloy steels, such as MO40-VCN-CK45-CK70, and color steels, like ALMINIUM BRONZ-PHOSPHOR BRONZ, mounted on an iron table.

[0011] The function of each part:

[0012] - A one-right-turn, three-phase electric motor facilitates the rotational movement of the holder with a step in a twisting mode, along with a reducer and increasing power gearbox. This ensures a consistent rotational force generated through electrical current, providing the necessary torque for the holder's rotation.

[0013] - To achieve the required radius for the holder's rotation, a connecting rod cap is installed after the gearbox outlet via an engine gearbox shaft that provides the initial rotation to the connecting rod.

[0014] - The connecting rods are designed to have varying cents and perform rotation based on the position of the connecting rod, radial outlet, and degree of angle. All three components - the crankshaft, small connecting rod (75.00 cents), and large connecting rod (80.00 cents) - exclusively rotate clockwise.

[0015] - To facilitate smooth rotation of the connecting rods and crankshaft, roller bearings have been installed in the upper parts of the centers within the pin plug gauge axis with HRC 60 hardness and 0.5 surface quality.

[0016] - To ensure precise placement of the roller bearings and gudgeon pins, as well as congruence of the connecting rods' height with the crankcase, round bottom bearings were employed on the lower edge of the connecting rods and the crank plate to eliminate any vertical reduction, and accurate and consistent circulation system.

[0017] - Four pieces of grease fitting have been used for lubrication to smooth the gudgeon pins with the roller bearings on the connecting rod body and the crank plate, preventing heat and wear.

[0018] - For the holder rotation, a thread is made in its body that is precisely in the same step as the spiral nut with bronze aluminum material, which is controlled by the similar step, and its material is different from the body so that the thread can be replaced in case of erosion and corrosion of the thread flank.

[0019] - The spiral nut is placed on the pin and nut plate, fixed by the holding plate. The spiral nut determines the position of the initial edge of the groove or socket (relative to the step and torsion) for the direction of the holder rotation in the process.

[0020] - The degree of charging is determined by the screw with a step of 1 mm, which is embedded on the screw plate.

[0021] - The rotation force of the charging screw is provided by a three-phase electric motor (with the possibility of two right and left turns) and two reduction compound and power gearboxes.

[0022] - To enable communication between the gearbox and the electric motor with a screw with low pitch, a gearbox engine shaft has been used. It is connected from the top to the gearbox bushing by a bolt, and from the other end, it is connected through a screw-engine mediating bushing.

[0023] - The opposite thread (nut) is embedded in the pin and nut plate to be placed precisely in the axis center of the holder and the charging screw with the minor slack.

[0024] - The pin and nut plate is connected to the screw plate by four guides 20 and four spring pins. These two plates are directed by a smooth vertical movement with a rail (guide), and the charging screw regulates the distance between them.

[0025] - Since the right-hand screw has a chipping mode, and the left-hand screw has a neutral state and a return to the original position, an electric motor, and a compound gearbox with two left and right rotations are used.

[0026] - The charging screw connected to the gearbox engine 1 RPM has a start and stop limit and two uses. First, to create the groove process by the chipping method, the screw must start charging right-turn relative to the cutting edge of the blades in the single holder, taking the lower limit position and the initial limit and right-turn command to the electric motor of the screw and proceed to the permitted limit of the chipping depth. Second, the chipping is completed after reaching the endpoint and taking the position of the upper limit, and the limit gives the electric motor the reverse command. To its original position for re-chipping, the screw gets a left-hand state.

[0027] - After reaching the lower stop limit, the chipping process begins by pressing the start button integrated into the switch and continues until the upper stop limit is activated. Then, we should press the end button on the switch (it is advised to open the component) to return to the start position and be ready to make the process in another component.

[0028] - To precisely adjust the X-Y-Z position of the workpiece, it is installed on the base fixture and on three axes of length, width, and height of the seat, maintaining and respecting the accuracy of the main chipping points.

[0029] - After installation, the parts are directed into their position in the base fixture and fixed with two clamps.

[0030] - The upper and lower clamps operate by two screws connected to the clamp top plate, and the clamp stop plate is connected to the bottom base by five screws

[0031] - In the main body of the holder (which passes through the workpiece), there are three tabs with the possibility of simultaneously measuring and chipping in width and length, consisting of two blades with a chipping diamond, including an upper diamond (single-tap) and a lower diamond (double-tap) and the three tabs can be controlled.

[0032] - To align the holder with the workpiece, the bottom plate, the base fixture, and two Horizontal guides (shivers) installed on the bottom plate are used, which are guided by the diameter of the holder guide in the width axis to the body of the holder. The longitudinal axis forms the exact position of AX through four rails mounted on the base plate and inside the Horizontal guides.

[0033] - Once the Horizontal guides are placed in their exact position (AX in the center of the device), they are fixed to the bottom base using two pins.

[0034] - Two electric motors and three gearboxes regulate the power and rate of rotation of the holder P40 for chipping and charging operations. To avoid vibrations and reinforcements in the lower part, we have used an engine base (the plate under the gearbox) and the mediating spacer for the plate under the gearbox. It is attached to the mediating plate via a screw from one side, and from the other end, it is connected to the engine base.

[0035] - To increase the speed, accuracy, and quality of the production and permanently eliminate the manpower, a motorized mechanism has been used instead of a mechanical mechanism. In this regard, a mediating plate is used, which mediates between the mechanical process, including the chipping mechanism (blade, holder, spiral nut), the charging mechanism (charging screw, screw adjustment plate, guide 20, springs), the fixtures (clamp, Horizontal guide, body stop clamp, clamp screw, clamp stop plate), and electric motor mechanism (automatic mode).

[0036] - To be more precise, four spacers 30 are embedded in the assembly of accessories during installation, connection, and assembly of engine accessories (automatic mode) with mechanical accessories (manual mode), connecting the base plate to the mediating plate with eight screws.

[0037] - The base plate is the first to be installed in the metal bed (table with base), and all the appliance components are installed and mounted on this plate.

[0038] - The base plate is both the entry and exit point of the workpiece.

[0039] - For precise guidance of the microswitch or limits, a microswitch guide is used, which is connected with two screws to the mediating plate on one side and to the base plate on the other side. From this guide to the chipping rate, we can determine and fix the limits' position performance (the groove height, starting first limit, and ending last limit of the groove aspect sizes).

[0040] - All the accessories of the device are mounted on a metal structure called the main table or base, which is also the entry and exit point of the components.

[0041] - The final position of the start and end of the spiral nut to connect to the gearbox engine shaft is one turn, and the chipping holder is determined by the mediating bushing, which is adjustable.

[0042] - A standard center bushing matches the cutting edge of diamonds or blades with the starting point of the holder tabs positioned based on the spiral nut.

[0043] - We use a step clamp on the upper edge of the holder to prevent trembling, vibration, and chipping of the cutting edge of blades or diamonds. It is connected to the body of the fixture base by two screws and ultimately leads to the accuracy and quality of the surface in the chipping part of the sockets.

[0044] - To address the raised issues, they have been assessed and resolved as follows:

[0045] 1- The torsion ratio with the special step of the internal groove is first created with the same torsion angle of the standard thread in the holder and the spiral nut of the desired step.

[0046] 2- A holder with the required number of tabs is built in three specific spots for chipping.

[0047] 3- Blades are embedded on three tabs with the same loading ratio (groove depth and torsion angle on the cutting edge) with the angle of chipping.

[0048] 4- Regarding the dimensional position on the first edge of the groove (the ratio of the exact dimensions of the first limit of the initial edge of the grooves and the height of the groove = 161.06 compared to the thread edge and the end position of the last edge of the groove= 151.23, the center-to-center limit of the groove edges are the ending point), the starting edge of the adjustable nut and the center start bushing were considered with the 360° rotatability.

[0049] 5- The first rotation direction and the return to the initial state are determined by the connecting rod concerning the length and the center of the position of the AX digits.

[0050] 6- Considering the screw with a low pitch with 1mm step, we minimize the productivity in chipping and design the theoretical system to implement the idea of using SOLIDWORK software. It confirms the desired amount of rotation relative to the calculated degree, angle, and depth of the load and the height of the blades.

[0051] The phases of manufacturing the device:

[0052] The bottom base plate (1), the base plate (2), the shaft spacer 30 (41), and the connection and outlet of the main base table (42) are connected through eleven screws. The base plate (2), which is the first center of the components, including the stop clamp plate (4), Horizontal guide (3), base fixture (10), bottom clamp (5), and upper clamp (6), fixes the workpiece (8) using two clamp screws (7). The base fixture (10) determines the exact X-Y-Z axes (width, length, and height) for fixing the component.

[0053] Once the workpiece (8) is placed in its position (the base fixture) through the workpiece outlet (21), the holder step 40 (43) with three tabs is located on it between the fixing pins 10 (44).

[0054] To prevent vibration, stop clamp (11) is placed on the upper edge of the holder step 40 (43) from one side and inside the fixing diameter 16.2 of the Horizontal guides (3) from the other side with two 8mm screws.

[0055] The start command is performed from the first starting point of the spiral nut 40 (52), which is located on the pin and nut plate (13) and is fixed to the screw installation plate (12) via four guides 20 (9).

[0056] The loading screw M20*1mm (22) and the location of four springs (15) are in the same line and have a holding role and passing guide 20 (9).

[0057] The starting point of the first tab of the blade's cutting edge is determined relative to the initial cent of charging in the socket.

[0058] The holder step 40 (43) is fixed in the location of the spiral nut (15) with a standard slack. The edges of the holder step P40 (43) are placed parallel to the edge of the T groove in the inner position of the workpiece (8). Holder step P40 (43) is connected to the cent start bushing (23) through the mediating bushing (19) and transmits the power from the gearbox engine 200RPM to the center connecting rod 75.00 (27).

[0059] The height adjustment is made through the bearing connection pin (47) with an accuracy of 0.01mm and alignment from the bearing 42 to 17 (24) and the round bottom bearing 35 to 20 (48). Finally, the bearing connection pin (47) reaches its longitudinal match by the thorn (49) and attaches to the center connecting rod 75.00 (27) with a thorn 5mm.

[0060] The connecting rods are connected via gudgeon pin 15 (30) and roller bearings 21 to 15 (31) to the center connecting rod 80.00 (28).

[0061] Finally, the center connecting rod 80.00 is attached to the connecting rod cap (29), which is fixed together with three screws of diameter 6 to accurately adjust the height (the distance between the connecting rods) and to prevent the pressure on the round bottom bearing 35 to 20 (50). One side of the connecting rod is a screw cap, and on the other side, a thread is embedded in the connecting rod body, in the interface of screw M6 to the socket, so they are not separated.

[0062] 5PCS grease fitting (40) lubricates connecting rods, intermediate location, round bottom bearings, and rolling bearings.

[0063] The primary power is transferred from the gearbox to the connecting rod cap through the gearbox engine shaft 200RPM (35). An 18-diameter thread is placed on its body, and a Round bottom bearing 47 to 25 (34) is used in the lower section to avoid messing up the setup.

[0064] To prevent the slack of the gearbox engine shaft 200RPM (35) to the gearbox engine busing 200RPM (45), we use two lock nuts (51), which are thin with some grooves on their outer diameter to be closed with a lock nut.

[0065] The gearbox engine 200RPM (45), responsible for the rotation of the connecting rods, is changed from 1330RPM to 200RPM using a reduction gearbox (to prevent chipping of the cutting edge of the blades and decreasing the temperature caused by the number of rotations of the connecting rods per minute) and the connecting rod cap (29), center connecting rod 75.00 (27), center connecting rod 80.00 (28), and their internal accessories (roller bearing, gudgeon pin, Round bottom bearing, screw M6) transmit the power.

[0066] This transition causes the current to circulate between 54 and 57 degrees (this must start and end at a certain point (it was explained at the beginning of the explanation of the entire process of starting and ending the nut to the holder, and all adjustments were done mechanically; no electronic system was implemented).

[0067] The charging rate in alignment with the rotation of 57 degrees is done by the loading screw M20*1mm (22), which is placed on the screw installation plate (12).

[0068] The thread is placed on the nut and pin plate (13) and passes through the retainer plate (14) and is connected directly to the screw engine mediating bushing (38) by the precise square 16, transmitting the loading power from the engine gearbox 1 (46) to the screw engine mediating bushing (38) by the thorn 6 on the gearbox engine shaft 1RPM (37). Finally, it advances to the limit step electric motor by the microswitch (upper limit step) (18) until the gearbox engine 200RPM (45) is cut off.

[0069] The holder step P40 (43) is connected parallel to the outlet slot and is placed on the workpiece (8) by the operator.

[0070] The engine gearbox 1 (46) is activated, and the current continues until it reaches the microswitch (lower limit step) (17) and the system is turned off (the return time is the same as the departure time).

[0071] It takes 5 minutes to produce 3 grooves of 5mm chipping. During the turnaround time, which is about 5 minutes, the operator can open the workpiece (8), remove the fixing pins (44), separate the Horizontal guides (3), clean the chips, and replace the next piece on the workpiece (21). The production is performed in the same way.Advantageous Effects of Invention
