Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a milling machine device for preparing automobile parts. Background Art

[0002] Auto parts are the various units that make up the whole car and a kind of product that serves the car. There are many kinds of auto parts. With the improvement of people's living standards, people's consumption of cars is increasing, and the market of auto parts is getting bigger and bigger. In the preparation process of auto parts, metal parts need to be precisely processed, and metal parts need to be polished by milling machine equipment.

[0003] When existing automobile parts milling machine equipment drills holes in metal parts, the drill bit cuts and drills the metal parts, which easily causes debris to splash, increasing the difficulty of cleaning the milling machine equipment for users. The metal debris generated by drilling can be recycled, but the splashed debris is not convenient for the staff to centrally handle. Therefore, a milling machine equipment for preparing automobile parts is introduced. Summary of the invention

[0004] The object of the present invention is to provide a milling machine device for preparing automobile accessories to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A milling machine device for preparing automobile parts comprises a processing machine tool, the processing machine tool comprises a supporting plate and a fixed frame rod, one side of the supporting plate is fixedly connected to the fixed frame rod, a connecting mechanism is arranged at the top of the fixed frame rod, a drilling mechanism is installed at one side of the connecting mechanism, a protective component is arranged at the bottom of the drilling mechanism, a positioning module is arranged on the upper surface of the supporting plate, and a workpiece is placed on the upper surface of the positioning module;

[0007] The drilling mechanism comprises a servo motor, one side of the servo motor is movably connected to the connecting mechanism, a drill bit is arranged on the bottom output shaft of the servo motor, and a through hole is opened inside the drill bit.

[0008] The connecting mechanism includes a transverse rotation module and a longitudinal rotation module. One side of the transverse rotation module is connected to a fixed frame rod. An electric linear slide is arranged at the top of the fixed frame rod. The transverse rotation module is movably connected to the fixed frame rod through the electric linear slide. The transverse rotation module includes a transverse rotation motor and a turntable. The turntable is connected to the electric linear slide. The transverse rotation motor is connected to the center of the turntable through an output shaft. The transverse rotation module is connected to the longitudinal rotation module through the turntable. The longitudinal rotation module includes a longitudinal rotation motor and a rotating shaft. One end of the rotating shaft is connected to the longitudinal rotation motor. The longitudinal rotation module is fixedly connected to the servo motor through the rotating shaft. Both the transverse rotation module and the longitudinal rotation module are connected and controlled through the central control platform. The electric linear slide at the top of the fixed frame rod is started to adjust the height of the drill bit in the drilling mechanism. The inclination angle of the drill bit is regulated by the transverse rotation module and the longitudinal rotation module to meet the multi-angle processing of the workpiece and improve the processing precision of the device.

[0009] The interior of the drill bit is set as a hollow structure through a through hole. The end of the drill bit close to the servo motor is connected to a cooling system through the through hole. The cooling system includes a storage box and stores coolant. The cooling system introduces the coolant into the through hole through a conduit. The drill bit rotates and drills by starting the servo motor. By introducing the coolant into the through hole, the coolant flows and absorbs the heat on the drill bit, and the drill bit is quickly cooled down. The coolant is ejected synchronously with the rotation of the drill bit to cool down the drilling point on the workpiece, avoiding the accumulation of chips caused by long-term high-temperature processing, resulting in the problem of built-up edge, and improving the drilling quality of the workpiece by the device.

[0010] The through hole is divided into two parts, the upper through hole coincides with the central axis of the drill bit, the lower through hole is horizontally and vertically arranged for the central axis, the inner wall of the lower through hole is arranged in an S shape, and the lower through hole is connected to the bottom of the upper through hole through the center point of the S shape. When the coolant flows through the through hole inside the drill bit, the coolant first passes through the upper part of the through hole to absorb and cool the heat on the drill bit, and then flows through the lower part of the through hole. The rotation of the drill bit drives the coolant to be ejected at a high speed, cools the processed holes on the workpiece, and takes out the accumulated debris inside.

[0011] The outer wall of the drill bit is provided with a spiral groove, the end of the through hole is located on the inner wall of the spiral groove on the drill bit, the aperture of the through hole close to the outer wall of the drill bit is larger than the aperture of the through hole close to the inside of the drill bit, and the arc deflection direction of the S-shaped arrangement inside the through hole is the same as the rotation direction of the drill bit. Through the S-shaped arrangement of the through hole, since the spiral groove provided on the drill bit is connected with the through hole, after the drill bit is inserted into the hole inside the workpiece, the rotation of the drill bit drives the coolant to flow and flush along the spiral groove on the drill bit, cleans the debris stuck inside the spiral groove, and improves the cleanliness of the drill bit. Since the aperture of the through hole close to the outer wall is larger, the problem of debris blocking the through hole is avoided.

[0012] The protective component includes a movable clamping ring, the inner wall of which is movably clamped with the bottom of the servo motor, the inner wall of which is arranged in an arc shape, the movable clamping ring and the bottom of the servo motor form a universal joint structure, a movable clamping rod is clamped on one side of the movable clamping ring, a mesh cover is arranged at the bottom end of the movable clamping rod, a spring is arranged at the end of the movable clamping rod close to the mesh cover, the top of the spring contacts the movable clamping ring, the bottom of the spring contacts the mesh cover, a rubber clamping ring is arranged at the bottom of the mesh cover, and the bottom of the mesh cover contacts the top of the workpiece through the rubber clamping ring. While adjusting the drill bit to rise and fall at the top position of the workpiece, the mesh cover is driven to contact the upper surface of the workpiece, the mesh cover pushes the movable clamping rod to slide along one side of the movable clamping ring, and at the same time cooperates with the movable clamping ring to squeeze and buffer the spring, the reaction force squeezes the workpiece to fix and tighten it, improves the stability of workpiece processing, blocks the debris through the mesh cover, reduces the splash of the debris, and blocks and buffers the coolant at the same time.

[0013] The positioning module includes a transverse slide rail, the bottom of which is fixedly connected to the support plate, a longitudinal slide rail is arranged on the upper surface of the transverse slide rail, a material placement plate is installed on the upper surface of the longitudinal slide rail, a workpiece is placed on the upper surface of the material placement plate, and drainage channels are equidistantly provided on the upper surface of the material placement plate. The workpiece is placed on the material placement plate, and the transverse and longitudinal slide rails are adjusted to adjust the relative position of the workpiece and the drilling mechanism, and the workpiece is quickly adjusted to the processing point to improve the automation of the device. While the drill bit rotates to process the workpiece hole, the mesh cover buffers the debris and coolant, so that part of the coolant and debris flows into the drainage channel on the material placement plate, which is convenient for the user to centrally process and recycle.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] 1. Through the arrangement of the drilling mechanism, the protection component and the positioning module, it is convenient for the user to centrally process the processing debris and recycle the metal debris. The coolant is sprayed through the through hole in the drill bit to quickly cool the drill bit and the processed holes of the workpiece, thereby avoiding the problem of built-up edge caused by the accumulation of debris under high-temperature processing, improving the processing quality of the device, and taking out the debris through the coolant. At the same time, the mesh cover buffers and filters the coolant and debris. The outflowing coolant is centrally recovered through the material placement plate, thereby improving the environmental protection of the device.

[0016] 2. By setting up the connecting mechanism, drilling mechanism, protective components and positioning modules, the degree of automation of the workpiece processing of this device is improved, which is convenient for the user to quickly adjust the processing point of the workpiece. Then the connecting mechanism cooperates with the protective components to adjust the drill bit to an appropriate angle. The universal joint structure formed by the mesh cover and the bottom of the servo motor through the movable retaining ring is convenient for processing irregular workpiece surfaces. At the same time, the bottom of the mesh cover is in contact with the workpiece surface to quickly fix the position of the workpiece, further improving the processing quality of this device.

[0035] The connecting mechanism 2 includes a transverse rotation module 201 and a longitudinal rotation module 202. One side of the transverse rotation module 201 is connected to the fixed frame rod 102. An electric linear slide is arranged on the top of the fixed frame rod 102. The transverse rotation module 201 is movably connected to the fixed frame rod 102 through the electric linear slide. The transverse rotation module 201 includes a transverse rotation motor and a turntable. The turntable is connected to the electric linear slide. The transverse rotation motor is connected to the center of the turntable through an output shaft. The transverse rotation module 201 is connected to the longitudinal rotation module 202 through the turntable. The longitudinal rotation module 202 includes a longitudinal rotation motor and a rotating shaft. One end of the rotating shaft is connected to the longitudinal rotation motor. The longitudinal rotation module 202 is fixedly connected to the servo motor 301 through the rotating shaft. The transverse rotating module 201 and the longitudinal rotating module 202 are both connected and controlled through the central control platform, and the electric linear slide rail at the top of the fixed frame rod 102 is started to adjust the height of the drill bit 302 in the drilling mechanism 3. The inclination angle of the drill bit 302 is regulated by the transverse rotating module 201 and the longitudinal rotating module 202 to meet the multi-angle processing of the workpiece 6 and improve the processing precision of the device.

[0036] The interior of the drill bit 302 is set as a hollow structure through the through hole 303. The end of the drill bit 302 close to the servo motor 301 is connected to a cooling system through the through hole 303. The cooling system includes a storage box and stores coolant. The cooling system introduces the coolant into the through hole 303 through a conduit. The drill bit 302 rotates and drills by starting the servo motor 301. By introducing the coolant into the through hole 303, the coolant flows and absorbs the heat on the drill bit 302, and the drill bit 302 is quickly cooled down. The coolant is ejected synchronously with the rotation of the drill bit 302 to cool down the drilling point on the workpiece 6, thereby avoiding the accumulation of chips due to long-term high-temperature processing, causing the problem of built-up edge, and improving the drilling processing quality of the workpiece 6 by the device.

[0037] The through hole 303 is divided into two parts, the upper through hole 303 coincides with the central axis of the drill bit 302, and the lower through hole 303 is horizontally and vertically arranged for the central axis. The inner wall of the lower through hole 303 is arranged in an S shape, and the lower through hole 303 is connected with the bottom of the upper through hole 303 through the center point of the S shape. When the coolant flows through the through hole 303 inside the drill bit 302, the coolant first passes through the upper part of the through hole 303 to absorb and cool the heat on the drill bit 302, and then flows through the lower part of the through hole 303. The rotation of the drill bit 302 drives the coolant to be ejected at a high speed, cools the processed hole on the workpiece 6, and removes the accumulated debris inside.

[0038] The outer wall of the drill bit 302 is provided with a spiral groove, and the end of the through hole 303 is located at the inner wall of the spiral groove on the drill bit 302. The aperture of the through hole 303 near the outer wall of the drill bit 302 is larger than the aperture of the through hole 303 near the inside of the drill bit 302. The arc deflection direction of the S-shaped arrangement inside the through hole 303 is the same as the rotation direction of the drill bit 302. Through the S-shaped arrangement of the through hole 303, since the spiral groove provided on the drill bit 302 is connected with the through hole 303, after the drill bit 302 is inserted into the hole inside the workpiece 6, the rotation of the drill bit 302 drives the coolant to flow and flush along the spiral groove on the drill bit 302, and the debris stuck inside the spiral groove is cleaned, thereby improving the cleanliness of the drill bit 302. Since the aperture of the through hole 303 near the outer wall is larger, the problem of debris blocking in the through hole 303 is avoided.

[0039] The protective component 4 includes a movable snap ring 401, the inner wall of the movable snap ring 401 is movably connected to the bottom of the servo motor 301, the inner wall of the movable snap ring 401 is arranged in an arc shape, the movable snap ring 401 and the bottom of the servo motor 301 form a universal joint structure, a movable clamping rod 402 is clamped on one side of the movable snap ring 401, a mesh cover 403 is arranged at the bottom end of the movable clamping rod 402, a spring is arranged at one end of the movable clamping rod 402 close to the mesh cover 403, the top of the spring is in contact with the movable snap ring 401, the bottom of the spring is in contact with the mesh cover 403, a rubber snap ring is arranged at the bottom of the mesh cover 403, and the bottom of the mesh cover 403 is in contact with the top of the workpiece 6 through the rubber snap ring. While regulating the drill bit 302 to rise and fall at the top position of the workpiece 6, the mesh cover 403 is driven to contact the upper surface of the workpiece 6. The mesh cover 403 pushes the movable clamping rod 402 to slide along one side of the movable clamping ring 401, and cooperates with the movable clamping ring 401 to squeeze and buffer the spring. The reaction force squeezes the workpiece 6 to fix and tighten it, thereby improving the stability of the workpiece 6 processing. The mesh cover 403 blocks the debris and reduces the splash of the debris, while blocking and buffering the coolant.

[0040] The positioning module 5 includes a transverse slide rail 501, the bottom of which is fixedly connected to the support plate 101, a longitudinal slide rail 502 is arranged on the upper surface of the transverse slide rail 501, a material placement plate 503 is installed on the upper surface of the longitudinal slide rail 502, a workpiece 6 is placed on the upper surface of the material placement plate 503, and drainage channels are equidistantly provided on the upper surface of the material placement plate 503. The workpiece 6 is placed on the material placement plate 503, and the transverse slide rail 501 and the longitudinal slide rail 502 are adjusted to adjust the relative position of the workpiece 6 and the drilling mechanism 3, and the workpiece 6 is quickly adjusted to the processing point, thereby improving the automation of the device. While the drill bit 302 rotates to process the hole of the workpiece 6, the mesh cover 403 buffers the debris and the coolant, so that part of the coolant and the debris flows into the drainage channel on the material placement plate 503, which is convenient for the user to centrally process and recycle.

[0041] Working principle of the present invention:

[0042] First, place the workpiece 6 on the material placement plate 503, adjust the horizontal slide rail 501 and the vertical slide rail 502 to adjust the relative position of the workpiece 6 and the drilling mechanism 3, and quickly adjust to the processing point. The horizontal rotation module 201 and the vertical rotation module 202 are connected and controlled through the central control platform, and the electric linear slide rail at the top of the fixed frame rod 102 is started to adjust the height of the drill bit 302 in the drilling mechanism 3. The inclination angle of the drill bit 302 is adjusted by the horizontal rotation module 201 and the vertical rotation module 202 to meet the multi-angle processing of the workpiece 6 and improve the processing precision of the device;

[0043] When the drill bit 302 is regulated to rise and fall at the top position of the workpiece 6, the mesh cover 403 is driven to contact the upper surface of the workpiece 6, and the mesh cover 403 pushes the movable clamping rod 402 to slide along one side of the movable clamping ring 401, and at the same time cooperates with the movable clamping ring 401 to squeeze and buffer the spring, and the reaction force squeezes the workpiece 6 to fix and tighten it, thereby improving the stability of the workpiece 6 processing, and the mesh cover 403 blocks the debris, reduces the splash of the debris, and at the same time blocks and buffers the coolant;

[0044] The drill bit 302 is lowered for drilling. The drill bit 302 rotates and drills by starting the servo motor 301. By introducing the coolant into the through hole 303, the coolant flows and absorbs the heat on the drill bit 302, and the drill bit 302 is quickly cooled down. The coolant is ejected synchronously with the rotation of the drill bit 302 to cool down the drilling point on the workpiece 6, so as to avoid the accumulation of chips due to long-term high-temperature processing and the problem of built-up edge, thereby improving the drilling quality of the workpiece 6 by the device. When the coolant flows through the through hole 303 inside the drill bit 302, the coolant first passes through the upper part of the through hole 303 to absorb and cool down the heat on the drill bit 302, and then flows through the lower part of the through hole 303. The rotation of the drill bit 302 drives the coolant to be ejected at a high speed, so as to cool down the processed hole on the workpiece 6 and bring out the accumulated chips inside.

[0045] Through the S-shaped setting of the through hole 303, since the spiral groove provided on the drill bit 302 is connected with the through hole 303, after the drill bit 302 is inserted into the hole inside the workpiece 6, the drill bit 302 rotates to drive the coolant to flow along the spiral groove on the drill bit 302 to flush the debris stuck inside the spiral groove, thereby improving the cleanliness of the drill bit 302. Since the aperture of the through hole 303 close to the outer wall is larger, the problem of debris blocking the through hole 303 is avoided;

[0046] While the drill bit 302 is rotating to drill the hole of the workpiece 6, the mesh cover 403 buffers the chips and the coolant, so that part of the coolant and the chips flow into the drainage channel on the material placement plate 503, which is convenient for the user to centrally process and recycle.
