Description

Technical Field

[0001] The invention relates to the technical field of bolt ball reference hole processing, and in particular to an automatic machine tool for processing grid bolt ball reference holes. Background Art

[0002] Bolt balls are mostly used in grid structures. The main structural features are: multiple holes with internal threads are opened on a ball to connect multiple rods at one point. At present, it is mainly completed by manual use of lathes, milling machines and other machine tools in multiple processing procedures. The reference hole is used as a reference to determine the position of other holes and facilitate the fixation of the bolt ball. When processing the reference hole, the bolt ball needs to be fixed to determine the position of the reference hole. During processing, a large number of chips of different sizes are often generated. The dusty chips are easy to generate dust, which affects the operator's vision and physical and mental health. Therefore, we proposed an automated machine tool for processing the grid bolt ball reference hole. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an automated machine tool for machining gantry bolt ball reference holes, comprising: A base plate, and a support plate symmetrically arranged on the top of the base plate; A base hole mechanism having a drive structure for automatically clamping a plurality of bolt balls; A cleaning mechanism, the cleaning mechanism having a screening structure for inhaling and treating dust; The top of the bottom plate is fixedly connected to the bottom of the support plate, the side of the support plate away from the bottom plate is fixedly connected to the side of the base hole mechanism close to the bottom plate, the side of the support plate away from the base hole mechanism away from the bottom plate is fixedly connected to the side of the cleaning mechanism close to the bottom plate, and the base hole mechanism and the cleaning mechanism are rotatably connected at their respective sides; Wherein, the base hole mechanism comprises: A rotating block, the rotating block being hollow and arranged in a hemispherical shape, and a transmission assembly arranged on a plane side of the rotating block; A fixed component, which is arranged on the arc surface of the rotating block, and is arranged obliquely along the tangent direction of the arc surface of the rotating block, and three fixed components are arranged along the circumference of the rotating block; The surface of the transmission assembly is fixedly connected to the inner side of the support plate away from the cleaning mechanism, and the side of the transmission assembly away from the support plate is fixedly connected to the plane side of the rotating block, and the side of the rotating block away from the transmission assembly is rotatably connected to the side of the cleaning mechanism close to the transmission assembly, and the fixed assembly is fixedly installed on the arc surface side of the rotating block, so that the transmission assembly is in a stopped state, and bolt balls are placed inside the three fixed assemblies, and the fixed assembly fixes the bolt balls, and then the transmission assembly is started, and the transmission assembly drives the rotating block to rotate intermittently. When a fixed assembly is at the top of the bottom plate, the transmission assembly stops rotating, and the reference hole is processed for the fixed bolt ball. At the same time, the reference ball processed in the top fixed assembly is taken out, and the reference ball is placed inside. At this time, since the fixed assembly is provided with three, the other two fixed The fixed components are located at the bottom and are symmetrical, and the bolt balls inside the two can be processed at the same time to improve processing efficiency. Another processing method is that the top fixed component is only used to add bolt balls, and the bolt ball inside a fixed component at the bottom is processed for reference hole processing, and the other fixed component is unfixed, so that the previously processed bolt ball rolls out close to the bottom plate. Rolling out close to the bottom plate can avoid the bolt ball from being damaged by impact, and can automatically complete the unloading after processing. Under this processing method, the required labor can be reduced. The fixed component is tilted along the tangent direction of the arc surface of the rotating block, which can expose the bolt ball to the maximum extent and facilitate the observation of the reference hole processing. The tilted setting can facilitate the sliding of chips, avoid chips remaining in the fixed component, and avoid affecting the subsequent processing of the bolt ball.

[0004] Furthermore, the transmission assembly includes a motor, the surface of the motor is fixedly connected to the inner side of the support plate away from the cleaning mechanism, the side of the motor close to the other support plate is fixedly connected with a rotating shaft, the rotating shaft is fixedly connected to the output end of the motor, and the side of the rotating shaft away from the motor is fixedly connected to the plane side of the rotating block. When the motor is started, the output end of the motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the rotating block to rotate, thereby driving the fixed assembly and the bolt ball fixed therein to rotate, thereby realizing continuous processing of the bolt ball.

[0005] Furthermore, the fixing assembly includes a connecting plate, which is fixedly connected to the arc surface side of the rotating block, and a connecting ring is fixedly connected to the side of the connecting plate away from the rotating block, and a plurality of connecting plates are arranged along the circumference of the connecting ring. The plurality of connecting plates form a cylindrical structure for placing bolt balls, and gaps are left between the connecting plates to ensure the falling of chips, avoid the accumulation of chips inside, avoid affecting the observation during the processing of the reference hole, and avoid affecting the fixation of the next bolt ball.

[0006] Furthermore, the first bent plate is fixedly connected to one side of the connecting plate near the center of the connecting ring, and the second bent plate is also fixedly connected to one side of the connecting plate near the center of the connecting ring, and the second bent plate is slightly longer than the first bent plate, and the second bent plate is arranged at the interval between the first bent plate and the rotating block, and an arc plate is arranged at the interval between the first bent plate and the second bent plate, and the two ends of the arc plate are respectively fixedly connected to one side where the first bent plate and the second bent plate are close to each other, and a driving assembly is arranged on one side of the arc plate near the connecting plate, and a bolt ball is placed in the connecting plate Inside the connecting ring and the connecting plate, the bolt ball first contacts the first bent plate, the first bent plate tilts, driving the arc plate to move, driving the second bent plate to tilt, and then the bolt ball enters the gap between the first bent plate and the second bent plate, and then the first bent plate, the arc plate, and the second bent plate are reset in turn, limiting the bolt ball at the gap between the first bent plate and the second bent plate to complete the pre-fixation. Since the second bent plate is slightly longer than the first bent plate, the bolt ball will not fall out of the gap between the first bent plate and the second bent plate, and during pre-fixation, the second bent plate is deformed and elongated, further preventing the bolt ball from falling out.

[0007] Furthermore, the first bent plate and the second bent plate are each provided with a deformation hole on a side away from the connecting plate, and the deformation hole is set to an elliptical shape. When the first bent plate and the second bent plate pre-fix the bolt ball, the sides of the two bent plates away from the connecting plate are squeezed by the bolt ball, and the deformation hole is deformed, so that during pre-fixation, it can adapt to bolt balls of various sizes, and the deformation hole set to an elliptical shape can just deform, so that the pre-fixation of bolt balls of different sizes can be completed more quickly.

[0008] Furthermore, the first bent plate and the second bent plate are close to each other at one end away from the connecting plate, and the first bent plate and the second bent plate are fixedly connected with friction rings at one end close to each other, and a plurality of friction rings are provided, and the friction rings are in contact with the bolt ball. The friction rings can increase the friction force with the bolt ball, thereby achieving a better fixing effect, and a plurality of friction rings are provided, which can increase the friction force along the circumference of the bolt ball, thereby avoiding the self-rotation of the bolt ball when drilling the reference hole, and avoiding affecting the drilling efficiency of the reference hole.

[0009] The cam is provided with an arc groove, and the surface of the slide frame is slidably connected to the inner wall of the slide groove, and a slide bar is provided at the interval of the slide frame, and two ends of the slide bar are fixedly connected to the inner side surface of the slide frame, and the surface of the arc groove is provided with an arc groove, and the surface of the slide bar is slidably connected to the inner wall of the arc groove. At a predetermined time, the arc plate moves and slides relatively with the slide bar, and the slide bar slides inside the arc groove. The arrangement of the arc groove and the slide bar can limit the movement of the arc plate, limit its movement trajectory, avoid arbitrary movement of the arc plate, avoid arbitrary inclination of the first bent plate and the second bent plate, thereby avoiding fatigue damage to the two. When fixed, the slide bar is driven to move, drive the slide frame to slide inside the slide groove, drive the arc plate to move, and finally drive the first bent plate and the second bent plate to open or approach each other, thereby completing the fixing and release of the bolt ball. The arrangement of the slide frame and the slide groove also plays a limiting role, so that the slide bar moves stably, avoids shaking, and ensures the fixing effect.

[0010] Furthermore, a limit rod is provided inside the arc groove, and both ends of the limit rod are fixedly connected to both sides of the inner wall of the arc groove respectively, and the limit rod passes through the sliding rod, and the surface of the limit rod is slidably connected to the inner wall of the sliding rod, and the number of the limit rods is set to be several. The limit rod is provided to further limit the movement of the arc plate at a predetermined time, to ensure that the arc plate moves along a predetermined trajectory, to avoid shaking, to avoid arbitrary tilting of the first bent plate and the second bent plate, thereby avoiding fatigue damage to the two. At the same time, the limit rod cooperates with the arc groove to limit, and can continue to play a limiting effect when the arc groove is worn or the limit rod is damaged.

[0011] Furthermore, the cleaning mechanism includes a pump body, a surface of the pump body is fixedly connected to the inner side of the support plate away from the motor, a connecting pipe is fixedly connected to the side of the pump body close to the rotating block, one end of the connecting pipe away from the pump body is rotatably connected to the inner wall of the rotating block, and the inner cavity of the connecting pipe is communicated with the hollow inner cavity of the rotating block, and an exhaust pipe is fixedly connected to the side of the pump body away from the connecting pipe. The pump body is started while processing, and the pump body drives the gas circulation inside the connecting pipe. The chips fall into the hollow inner cavity of the rotating block and are then sucked into the connecting pipe and finally discharged from the exhaust pipe, thereby completing the cleaning of the chips, avoiding the generation of dust, and ensuring the operator's observation field of view during the reference hole processing.

[0012] Furthermore, a four-way groove is provided in the inner cavity of the rotating block, and the inner cavity of the four-way groove is connected with the inner cavity of the connecting pipe. A cover body is provided on the side of the four-way groove away from the connecting pipe, and the surface of the cover body is fixedly connected to the inner wall of the four-way groove. The cover body is provided with a plurality of covers along the circumference of the rotating block, and a shell is fixedly connected to the side of the cover body away from the connecting plate, and the shell is set in a spherical shape. A coarse filter groove is provided on the surface of the cover body, and a fine filter hole is provided on the surface of the shell. The connecting pipe generates suction, which drives the four-way groove to generate suction, so as to inhale the chips and dust generated by the processing. The dust passes through the coarse filter trough, fine filter holes, four-way groove, connecting pipe, pump body in turn, and is finally discharged from the exhaust pipe, completing the centralized treatment of chips and dust, facilitating subsequent recycling and reuse, and avoiding dust in the operating environment to ensure the physical and mental health of operators. The coarse filter trough can intercept large-particle chips, which then roll down into the shell. The shell with fine filter holes can prevent slender and curled chips from passing through, and prevent large-particle chips from clogging the pipeline. As the rotating block rotates, it rolls down to the outside of the cover, and finally falls to the top of the bottom plate, facilitating the recycling of large-particle chips.

[0013] The present invention has the beneficial effects: 1. The present invention provides three fixing components. The other two fixing components are located at the bottom and are symmetrical. The bolt balls located inside the two fixing components can be processed at the same time, thereby improving the processing efficiency. Alternatively, the bolt ball inside one fixing component at the bottom is processed with a reference hole, and the other fixing component is unfixed, so that the previously processed bolt ball rolls out close to the bottom plate. Rolling out close to the bottom plate can prevent the bolt ball from being damaged by impact, and can automatically complete the unloading after processing. In this processing method, the required labor can be reduced. The fixing components are tilted along the tangent direction of the arc surface of the rotating block, so that the bolt ball can be exposed to the maximum extent, which is convenient for observing the processing of the reference hole. The tilted setting can facilitate the sliding out of chips, thereby preventing chips from remaining inside the fixing components and affecting the subsequent processing of the bolt balls.

[0014] 2. The present invention sets a first bent plate and a second bent plate, and the bolt ball enters the gap between the first bent plate and the second bent plate. Then the first bent plate, the arc plate, and the second bent plate are reset in sequence, and the bolt ball is limited at the gap between the first bent plate and the second bent plate to complete pre-fixation. Since the second bent plate is slightly longer than the first bent plate, the bolt ball will not fall out of the gap between the first bent plate and the second bent plate. During pre-fixation, the second bent plate is deformed and elongated, further preventing the bolt ball from falling out and causing deformation of the deformation hole. Therefore, during pre-fixation, it can adapt to bolt balls of various sizes, and the deformation hole is set to an elliptical shape, which can just produce deformation and complete the pre-fixation of bolt balls of different sizes more quickly.

[0015] 3. The present invention sets an arc groove. The setting of the arc groove and the slide rod can limit the movement of the arc plate, limit its movement trajectory, avoid arbitrary movement of the arc plate, and avoid arbitrary tilting of the first bent plate and the second bent plate, thereby avoiding fatigue damage to the two. The setting of the slide frame and the slide groove also plays a limiting role, allowing the slide rod to move stably, avoiding shaking, and ensuring the fixing effect.

[0016] 4. The present invention sets a cleaning mechanism, and the chips and dust pass through the coarse filter groove, fine filter holes, four-way groove, connecting pipe, pump body in turn, and are finally discharged from the exhaust pipe, completing the centralized treatment of chips and dust, facilitating subsequent recycling and reuse, and avoiding dust generation in the operating environment, ensuring the physical and mental health of operators. The coarse filter groove can intercept large-particle chips, and then the large-particle chips roll into the inside of the shell. The shell with fine filter holes can prevent slender and curled chips from passing through, and prevent large-particle chips from clogging the inside of the pipeline. As the rotating block rotates, the chips roll to the outside of the cover body, and finally fall to the top of the bottom plate, which is convenient for the recovery of large-particle chips.

[0030] When the bolt ball is in use, it is placed in the connecting ring 332 and the connecting plate 331, and the bolt ball first contacts the first curved plate 333, which causes the first curved plate 333 to tilt, thereby driving the arc plate 335 to move and driving the second curved plate 334 to tilt. Then, the bolt ball enters the gap between the first curved plate 333 and the second curved plate 334, and then the first curved plate 333, the arc plate 335, and the second curved plate 334 are reset in sequence, and the bolt ball is limited at the gap between the first curved plate 333 and the second curved plate 334 to complete the pre-fixation. When fixing, the sliding rod 3362 is driven to move, driving the sliding frame 3361 to slide in the sliding groove 3366, driving the arc plate 335 to move, and finally driving the first curved plate 333 and the second curved plate 334 to open or approach each other, thereby completing the fixing and loosening of the bolt ball, and starting the motor 321. The output end of the motor 321 drives the rotating shaft 322 to rotate, and the rotation of the rotating shaft 322 drives the rotating block 31 to rotate, thereby driving The movable fixing component 33 and the bolt ball fixed therein rotate intermittently. When the bolt ball stops, the reference hole is processed. While processing, the pump body 41 is started, and the connecting pipe 42 generates suction, which drives the suction inside the four-way groove 44 to suck in the chips and dust generated by the processing. The chips and dust pass through the coarse filter groove 47, the fine filter hole 48, the four-way groove 44, the connecting pipe 42, and the pump body 41 in turn, and are finally discharged from the exhaust pipe 43. When a fixing component 33 is at the top of the base plate 1, the transmission component 32 stops rotating, the reference hole is processed for the fixed bolt ball, and the processed reference ball in the top fixing component 33 is taken out and placed inside. Another processing method is that the top fixing component 33 is only used to add bolt balls, and the bolt ball inside a fixing component 33 at the bottom is processed for reference hole processing, and the other fixing component 33 is unfixed, so that the previously processed bolt ball rolls out close to the base plate 1.
