Description

Technical Field

[0001] This invention relates to the field of parts processing technology, specifically to an automated CNC machine tool for bushing processing. Background Technology

[0002] A fuel tank bushing is a hollow shaft-shaped structural component that is inserted and fixed to the fuel tank wall. It is held between two bushings and the tank wall, with a wire mesh gasket between the bushings and the tank wall. One existing manufacturing method for bushings involves first manufacturing a steel pipe, then cutting the pipe into sections using cutting equipment to produce the bushings. After cutting a section of the steel pipe, it needs to be fed. Currently, a feeding device is generally used. Before feeding, a sensor is typically used to detect the cut length of the steel pipe. The feeding device then clamps and feeds the steel pipe, thus achieving automatic feeding.

[0003] However, in the current technology, during the processing of bushings, the feeding mechanism feeds the steel pipe one at a time and then grinds it into shape. There are intervals between feeding rates, which makes the processing efficiency of bushings insufficient to meet the needs of existing bushing processing enterprises. Therefore, it is necessary to propose a new automated CNC machine tool for bushing processing. Summary of the Invention

[0004] The purpose of this invention is to provide an automated CNC machine tool for bushing processing, in order to solve the technical problem mentioned in the background art that there are intervals between the feeding rates during the bushing processing operation, which makes the bushing processing efficiency insufficient to meet the needs of existing bushing processing enterprises.

[0006] The rotating machine assembly includes a base, on which a rotary motor is mounted, and a planetary gear set is provided inside the base. The output shaft of the rotary motor and the planetary gear set are installed together. The base is provided with a mounting groove, and a rotating annular guide rail is provided inside the mounting groove. The planetary gear set includes at least three sets of planetary gears, and the rotating shafts of the planetary gears are connected to the rotating annular guide rail.

[0007] The clamping transmission assembly includes a connecting vertical rod, a connecting housing connected to the connecting vertical rod, and a motor mounted on the connecting housing. A rotatable turntable is installed around the periphery of the connecting housing. The motor drives the turntable to rotate. The turntable has eight sets of docking holes around its periphery, and grinding steel pipes are plugged into the eight sets of docking holes.

[0008] Preferably, the side adjustment assembly includes a top cover frame, and two sets of columns are welded and installed on the front bottom wall surface of the top cover frame, with a second electric push rod installed inside the two sets of columns.

[0009] Preferably, the output shaft of the second electric push rod is connected to a connecting seat, the inner walls of the two sets of columns are provided with upper and lower sliding grooves, and the two sets of columns are provided with auxiliary sliding grooves, wherein the connecting seat is slidably connected to the auxiliary sliding grooves through a sliding block.

[0010] Preferably, a connecting slide rod is sleeved on the outside of the bottom rod of the second electric push rod, and the left and right ends of the connecting slide rod are slidably connected to the upper and lower sliding grooves.

[0011] Preferably, the lifting and adjusting assembly includes a reinforcing support rib, which is fastened to the back surface of the base, and a guide rail frame is fastened to the top of the reinforcing support rib. The inner surface of the guide rail frame is provided with a raised sliding strip.

[0012] Preferably, a stepper motor is externally mounted on the guide rail frame, and a ball screw is installed inside the guide rail frame. The stepper motor drives the ball screw to rotate with the cooperation of the bearing seat. A connecting frame block is installed and slidably between the ball screw and the convex slide bar. A reinforcing rod is fastened to the bottom of the guide rail frame.

[0013] Preferably, a protective base is installed on the top of the operating platform, an electric displacement guide rail is provided inside the protective base, a displacement block is slidably installed on the outside of the electric displacement guide rail, a grinding machine is fastened to the top of the displacement block, and a grinding head is installed on the outside of the grinding machine.

[0014] Preferably, a sliding base is fastened to the top of the grinder, and an adjusting groove is provided on the top surface of the sliding base. A pipe clamp block is slidably connected inside the adjusting groove.

[0015] Preferably, a water pipe is connected to the top surface of the liquid-cooled water tank, and the water pipe is installed through the sliding base and the pipe clamp block.

[0016] Preferably, an operation panel is installed on the outer wall surface of the operating platform. The operation panel is connected and controlled by a liquid cooling water tank, a first electric push rod, a rotary motor, a motor, a second electric push rod, an electric displacement guide rail, and a grinding machine via wiring.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In this invention, through the cooperation of the rotating platform assembly, lifting adjustment assembly, side adjustment assembly, and clamping transmission assembly, after the displacement decreases to a preset position using the lifting adjustment assembly, the second electric push rod is activated using the operation panel. This second electric push rod drives the connecting vertical rod, connecting housing, motor, and rotary table to retract, thereby allowing the mating hole and the ejector end to engage. After the engagement is completed, the rotary motor and the rotating wheel are simultaneously activated. The rotary motor drives the planetary gear set and the rotating annular guide rail to rotate inside the mounting groove. Simultaneously, the planetary gear set creates a speed reduction group for the rotating annular guide rail, ensuring uniform rotation. Subsequently, the motor also drives the rotary table to rotate at the same speed as the rotating annular guide rail, in the same clockwise direction. During the synchronous operation of the rotating annular guide rail and the rotary table, the first electric push rod, acting on the first electric push rod, pushes the grinding steel pipe placed in the limiting mounting groove into the mating hole. Afterwards, the grinding machine is started to grind the steel pipe at a preset speed. This ensures that the ejection speed of the top block is the same as the processing speed of the steel pipe, reducing the problem of intervals in the feeding speed, improving the automatic feeding speed of bushing processing, and increasing the overall economic efficiency of the company's product production and sales.

[0019] 2. In this invention, the stepper motor is activated by the cooperation of the lifting and adjusting components and the side adjusting components. This drives the connecting frame block to move up and down inside the guide rail frame under the cooperation of the ball screw and the convex slide bar. When the connecting frame block is adjusted for displacement, it can drive the second electric push rod, the connecting seat, the connecting vertical rod, the connecting housing, the motor, and the rotary table to adjust the descent distance synchronously. Then, when the second electric push rod and the connecting seat are displaced, the horizontal stability of the second electric push rod and the connecting seat can be ensured by the cooperation of the upper and lower sliding grooves and the auxiliary sliding groove.

[0020] 3. In this invention, with the cooperation of the first electric push rod, the automatic conveyor belt, the rotating machine assembly, and the clamping transmission assembly, when the bushing is being processed, the automatic conveyor belt can automatically and uniformly transport the steel pipe to be ground. The operation of the electric displacement guide rail allows the displacement block to move the grinding machine to a preset position inside the protective base, moving it to the front end of the steel pipe in the mating hole. The grinding head then grinds the steel pipe. After grinding, the processed steel pipe is ejected by the ejector end and falls into an external collection box for collection. The grinding machine then returns to its initial position, and the first electric push rod restarts, repeating the automatic feeding and processing of the bushing in a reciprocating manner, thus improving the efficiency of the bushing processing.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Refer to Figures 1-8 The image shows an automated CNC machine tool for machining bushings. The machine tool includes an operating table 1, with a rotating table assembly 15 integrally formed on one side. A groove 20 is formed in the middle of the operating table 1 and the rotating table assembly 15. A lifting adjustment assembly 16 is connected to the back surface of the rotating table assembly 15. A side adjustment assembly 17 is fastened to the side end of the lifting adjustment assembly 16, and a clamping transmission assembly 18 is fastened to the side end of the side adjustment assembly 17. The operating table 1 has a conveying trough 12, on which an automatic conveyor belt 14 is installed. A liquid-cooled water tank 10 is installed on the operating table 1, and a first electric push rod 11 is mounted on the liquid-cooled water tank 10. A top block 13 is installed at the front end of the first electric push rod 11.

[0032] The rotating machine assembly 15 includes a base 151, on which a rotary motor 154 is mounted. A planetary gear set 152 is disposed within the base 151, and the output shaft of the rotary motor 154 and the planetary gear set 152 are mounted together. The base 151 has a mounting groove, within which a rotating annular guide rail 153 is disposed. The planetary gear set 152 is connected to the rotating annular guide rail 153 via rotating shafts mounted on the inner sides of three sets of planetary gears. The clamping transmission assembly 18 includes a connecting vertical rod 181, with a connecting housing 182 securely connected to the bottom of the connecting vertical rod 181. A motor 183 is mounted on the outside of the connecting housing 182, and a rotatable turntable 184 is mounted around the periphery of the connecting housing 182. The motor 183 drives the turntable 184 to rotate. The turntable 184 has eight sets of mating holes 185 arranged around its periphery, and grinding steel pipes 186 are plugged into the eight sets of mating holes 185.

[0033] The effect achieved in Embodiment 1 is that when the bushing needs to be processed, the steel pipe to be processed is placed sequentially in the limiting installation grooves set on the surface of the automatic conveyor belt 14. The limiting installation grooves are evenly distributed on the surface of the automatic conveyor belt 14 to facilitate uniform speed during material feeding. Next, the eight sets of docking holes 185 on the surfaces of the rotating annular guide rail 153 and the rotary table 184 are aligned and installed on the same horizontal line. Thus, when material feeding is required, a control signal can be sent to the rotary motor 154 under the control of the operation panel 19. When the rotary motor receives the signal, the rotary motor 154 can drive the planetary gear set 152 and the rotating annular guide rail 153 to rotate. The rotating annular guide rail 153 rotates inside the installation groove, and the planetary gear set 152 forms a reduction structure, ensuring that the rotation speed of the rotating annular guide rail 153 is uniform. Simultaneously, after the eight sets of mating holes 185 on the surface of the rotary table 184 and the ejector end on the surface of the rotating annular guide rail 153 are fitted together, a control signal is sent to the motor 183 via the operation panel 19. This causes the motor 183 to start and drive the rotary table 184 to rotate. The rotary table 184 and the rotating annular guide rail 153 rotate at the same speed and in the same clockwise direction. Then, under the action of the first electric push rod 11, the top block 13 is driven to eject the grinding steel pipe 186 placed in the limiting mounting groove into the mating hole 185. According to the preset speed, the ejection speed of the top block 13 by the first electric push rod 11 is the same as the processing speed at which the grinding steel pipe 186 is ground and shaped by the grinding machine 5 and the grinding head end 6. After a grinding steel pipe 186 is ground and recycled, the bushing formed by the grinding steel pipe 186 can be ejected by the ejector end and fall into the external collection box for collection and sorting. The operation of the overall structure reduces the problem of interval in the feeding rate, improves the automatic feeding rate of bushing processing, and increases the economy of the company's overall product production and sales.

[0034] Example 2: According to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the side adjustment assembly 17 includes a top cover frame 171. Two sets of columns 173 are welded and installed on the front bottom wall surface of the top cover frame 171. A second electric push rod 172 is provided inside the two sets of columns 173. The output shaft of the second electric push rod 172 is connected to a connecting seat 174. The inner walls of the two sets of columns 173 are provided with upper and lower sliding grooves 176, and the two sets of columns 173 are provided with auxiliary sliding grooves 177. The connecting seat 174 is slidably connected to the auxiliary sliding groove 177 through a sliding block. A connecting slide rod 175 is sleeved on the outside of the bottom rod of the second electric push rod 172, and the left and right ends of the connecting slide rod 175 are slidably connected to the upper and lower sliding grooves 176. The lifting adjustment assembly 16 includes a reinforcing support rib 160, which is fastened to the back surface of the base 151. A guide rail bracket 161 is securely mounted on the top of the reinforcing support rib 160. A raised sliding strip 162 is provided on the inner surface of the guide rail bracket 161. A stepper motor is mounted on the outside of the guide rail bracket 161, and a ball screw 163 is installed inside the guide rail bracket 161. The stepper motor drives the ball screw 163 to rotate with the cooperation of the bearing seat. A connecting bracket block 164 is slidably mounted on the outside of the ball screw 163 and the raised sliding strip 162, and a reinforcing rod 165 is securely connected to the bottom of the guide rail bracket 161.

[0035] The effect achieved in Embodiment 2 is that, during machining operations on the bushing, the stepper motor can be activated to drive the connecting block 164 to move up and down within the guide rail frame 161 in cooperation with the ball screw 163 and the convex slide bar 162. During the displacement adjustment of the connecting block 164, the second electric push rod 172 and the connecting seat 174 are simultaneously moved up and down. During the displacement of the second electric push rod 172 and the connecting seat 174, they can simultaneously slide up and down on the inner wall surfaces of the two sets of columns 173 in cooperation with the upper and lower sliding grooves 176 and the auxiliary sliding groove 177, ensuring the horizontal stability of the displacement of the second electric push rod 172 and the connecting seat 174. Afterwards, when the second electric push rod 172 drives the clamping transmission assembly 18 to the preset position, the second electric push rod 172 can be controlled to retract again, driving the rotary table 184, the eight sets of docking holes 185 and the ejector end of the rotating annular guide rail 153 to engage and fit together, ensuring the clamping and processing operation of the grinding steel pipe 186.

[0036] Example 3: According to Figure 1 , Figure 2 and Figure 3As shown, a protective base 2 is installed on the top of the operating platform 1. An electric displacement guide rail 3 is installed inside the protective base 2. A displacement block 4 is slidably installed on the outside of the electric displacement guide rail 3. A grinder 5 is fastened to the top of the displacement block 4. A grinding head end 6 is installed on the outside of the grinder 5. A sliding base 7 is fastened to the top of the grinder 5. An adjusting groove is opened on the top surface of the sliding base 7. A pipe clamp block 8 is slidably connected inside the adjusting groove.

[0037] A water pipe 9 is connected to the top surface of the liquid cooling water tank 10, and the water pipe 9 is installed through the sliding base 7 and the pipe clamp block 8. An operation panel 19 is installed on the outer wall surface of the operating platform 1, and the operation panel 19 is connected and controlled by the liquid cooling water tank 10, the first electric push rod 11, the rotary motor 154, the motor 183, the second electric push rod 172, the electric displacement guide rail 3 and the grinding machine 5 through wiring.

[0038] The effect achieved in Embodiment 3 is that after the grinding steel pipe 186 is placed, the electric displacement guide rail 3 can be controlled by the operation panel 19 to drive the displacement block 4 and the grinding machine 5 to move back and forth inside the protective base 2, thereby starting the grinding machine 5 to drive the grinding head end 6 to perform sequential grinding operations on the grinding steel pipe 186. At the same time, during the grinding process, the liquid cooling water tank 10 can be used to cool the grinding steel pipe 186 through the water pipe 9, and the water pipe 9 can be supported and fixed with the cooperation of the pipe clamp block 8. The pipe clamp block 8 can be slidably adjusted inside the adjusting groove, which facilitates the adjustment of the position of the water pipe 9 and reduces the problem that the position of the water pipe 9 cannot be changed when the coolant is poured on the grinding steel pipe 186 during the fixed installation.

[0039] The working process of this device is as follows: First, when performing bushing processing, the automatic conveyor belt 14 automatically and uniformly conveys the steel pipe 186 to be ground. The stepper motor drives the connecting frame block 164 to move up and down along the inside of the guide rail frame 161 under the cooperation of the ball screw 163 and the convex slide bar 162. When the connecting frame block 164 is adjusted in displacement, it can drive the second electric push rod 172, the connecting seat 174, the connecting vertical rod 181, the connecting housing 182, the motor 183, and the rotary table 184 to adjust the synchronous descent distance. When the second electric push rod 172 and the connecting seat 174 move, the horizontal stability of the displacement of the second electric push rod 172 and the connecting seat 174 can be ensured with the cooperation of the upper and lower sliding grooves 176 and the auxiliary sliding grooves 177.

[0040] When the displacement of the connecting seat 174 reaches the preset position, the first electric push rod 11 drives the top block 13 to push the grinding steel pipe 186 placed in the limiting installation groove into the docking hole 185. The second electric push rod 172 is activated through the operation panel 19, which drives the connecting vertical rod 181, the connecting housing 182, the motor 183 and the rotary table 184 to retract, so that the eight sets of docking holes 185 and the ejected end are fitted together, ensuring the clamping and processing operation of the grinding steel pipe 186.

[0041] After the grinding steel pipe 186 is installed, the rotary motor 154 and motor 183 are started synchronously. The rotary motor 154 drives the planetary gear set 152 and the rotating annular guide rail 153 to rotate inside the mounting slot. Simultaneously, the planetary gear set 152 ensures that the rotational speed of the rotating annular guide rail 153 is a uniform speed reduction gear. The rotational speed and direction of the rotary disk 184 driven by the motor 183 are the same as the uniform speed of the rotating annular guide rail 153, thus achieving synchronous operation between the rotating annular guide rail 153 and the rotary disk 184.

[0042] Next, the grinding machine 5 is started to grind the steel pipe 186. The rotary table 184, according to the preset speed, ensures that the ejection speed of the top block 13 is the same as the processing speed of the steel pipe 186. Under the control of the operation panel 19, the electric displacement guide rail 3 and the grinding machine 5 are started. The rotation of the displacement guide rail 3 causes the displacement block 4 to drive the grinding machine 5 to reciprocate within the protective base 2 at a preset position. When it moves to the front end of the steel pipe 186 in the docking hole 185, the grinding head end 6 is used to grind and shape the steel pipe 186.

[0043] After grinding, the ground steel pipe 186 can be ejected from the top end of the rotating displacement guide rail 3 and fall into the external collection box for collection. Simultaneously, during the grinding process, the ground steel pipe 186 can be cooled by the liquid cooling water tank 10 through the water pipe 9. With the cooperation of the pipe clamp block 8, the water pipe 9 can be supported and fixed, and the pipe clamp block 8 can slide and adjust within the adjusting groove to facilitate the adjustment of the water pipe 9's position. With the cooperation of the electric displacement guide rail 3, the grinding machine 5 returns to its initial position, and the first electric push rod 11 starts again, automatically feeding the ground steel pipe 186 placed in the limiting installation groove in a reciprocating motion.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
