Description

Technical Field

[0001] The invention relates to the technical field of screw slides, in particular to a two-dimensional motion screw slide suitable for spraying processing. Background Art

[0002] The screw slide can achieve more precise and accurate positioning through the programmable control system and the stepper motor or servo motor. This high-precision positioning allows the spraying work to be completed more evenly and finely, thereby improving the quality and efficiency of the spraying. During the manual spraying process, workers need to be exposed to paint and harmful gases for a long time, which poses a serious threat to the health of workers. The linear slide automatic paint spraying machine effectively prevents the adverse effects of paint dust on workers through the design of dust covers, safety doors and protective windows, reduces the contact of human hands, and reduces the risk of bacterial infection, thereby ensuring the health and safety of workers.

[0003] The paint produced during the spraying work will fall into the inside of the slide and gradually solidify, which will affect the operation of the slide. The inside of the slide is difficult to clean, which will reduce the service life of the equipment. The screw slide needs regular maintenance and lubricating oil when in use. The existing screw slide usually needs to be disassembled and manually added, which will cause the spraying work to stop, thereby reducing the product production speed. Summary of the invention

[0010] Furthermore, the top of the sliding seat is fixedly connected to a limiting seat, and two clamping frames are symmetrically slidably embedded in the limiting seat, and cylinder 2 is fixedly connected to the side walls of the two clamping frames.

[0011] Furthermore, the two sliding seats are arranged in an alternating and symmetrical manner.

[0012] Furthermore, the end of the ball screw is rotatably connected to an adjustment seat, and a hydraulic cylinder fixedly connected to a slide rail is fixedly connected to a side wall of the adjustment seat.

[0014] Furthermore, the length of the ball screw is equal to the inner length of the slide rail.

[0015] Furthermore, the closing mechanism includes a round shell fixedly connected to the slide rail, a winding wheel is rotatably connected inside the round shell, a spring steel belt fixedly connected to the side wall of the sliding seat is sleeved on the outside of the winding wheel, the spring steel belt is slidably embedded in the slide rail and the top cover, a clockwork spring is fixedly connected to the rotating shaft of the winding wheel, and a disc is sleeved on the outside of the clockwork spring.

[0016] Furthermore, the lubrication mechanism includes two cavity columns fixedly arranged inside the sliding seat, a plurality of steel balls are movably connected at equal distances in the cavity columns, a branch pipe is fixedly connected between the two cavity columns, one end of the branch pipe is fixedly connected to one end of a hose, the other end of the hose is fixedly connected to an extrusion column, a conical head is fixedly connected to the side wall of the extrusion column, the outside of the conical head is fixedly sleeved with a piston cylinder, the outside of the piston cylinder is slidably sleeved with a pumping cylinder, and the end of the piston cylinder is fixedly connected to an extrusion spring.

[0017] Furthermore, a connecting column is fixedly connected to the end of the liquid extraction cylinder, a suction tube connected thereto is fixedly connected to the center of the connecting column, an oil storage box is fixedly connected to the outside of the suction tube, and the oil storage box is fixedly connected to the side wall of the sliding seat.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Two sliding seats are arranged in an interlaced and symmetrical manner inside the screw slide. The output ends of the two driving motors can drive the coupling to rotate, and then the coupling drives the driving shaft to rotate, so as to drive the two ball screws to rotate in opposite directions, thereby driving the two sliding seats in the slide to move in opposite directions. In this way, the workpiece can be loaded from one end of the slide and transported to the other end of the slide through one of the two sliding seats. During the movement, the front and back sides of the workpiece are sprayed by two spraying robots. After arriving at the other end of the slide, the sprayed workpiece is unloaded. During unloading, the other sliding seat can load the next workpiece to be sprayed. , and then repeat the above operation, so that the two sliding seats can ensure that one of the sliding seats is loaded with a new workpiece to be sprayed during each staggered movement of the two sliding seats in the slide rail, thereby improving the spraying efficiency of the product, and the adjustment seat can be driven to move by the extension of the hydraulic cylinder, thereby driving the ball screw to slide on the drive shaft, so that the ball screw can be removed for inspection. When damage is found on the surface of the ball screw, it can be convenient to repair it. By adjusting the distance between the two sliding seats, the two sliding seat clamps can clamp thicker objects one after the other and move in the same direction, so that the device can perform mobile spraying on large objects.

[0021] 2. The sliding seat and the slide rail are arranged to slide in an embedded manner, and a top cover is arranged on the top of the slide rail to protect the ball screw, thereby preventing paint mist from falling on the ball screw and the inside of the slide rail and gradually solidifying to cause serious wear of the equipment. The sliding seat can pull one end of the spring steel belt on the two side walls to move during the movement. Since the spring steel belt is wound around the outside of the winding wheel and a clockwork spring is arranged on the central axis of the winding wheel, the spring steel belt can be kept straight at all times when the sliding seat moves, so as to close the gap between the slide rail and the top cover, thereby completely closing the inside of the screw slide. This not only prevents dust and pollution, but also protects the internal mechanical structure from dust, debris and other pollutants, but also ensures the high precision and high stability of the slide during the sliding process. The closed screw slide can reduce the frequency and cost of mechanical maintenance.

[0022] 3. When it is necessary to add lubricating oil to the surface of the ball and screw, the cylinder can first be used to drive the moving plate close to the end of the slide rail, so that the moving plate can drive the connecting rods on both sides to swing, so that the end of the connecting rod can drive the rotating plate to rotate until it remains flush with the side plate of the slide rail. In this way, when the sliding seat moves to the end of the slide rail, it will drive the extrusion column and the rotating plate to conflict with each other, so that the piston cylinder can be pressed into the pumping cylinder, and then the valve ball can be squeezed out of the conical head under the action of hydraulic pressure. The lubricating oil will be squeezed from the pumping cylinder into the extrusion column and the hose, and then it will be discharged into the branch pipe and the two cavity columns. Multiple steel balls will contact the lubricating oil in the cavity column when rolling. Lubrication, and then the lubricating oil on the surface of the steel ball can lubricate the ball screw. When the extrusion column and the rotating plate no longer conflict with each other, the return spring will squeeze the valve ball to block the opening of a pair of conical heads, and then the extrusion spring can squeeze the piston cylinder to return to its original position, thereby driving the valve ball to move inside the connecting column under the action of negative air pressure, so that the suction tube uses the opening at the end of the connecting column to be connected with the inside of the liquid pumping cylinder, so that the lubricating oil in the oil storage box can be sucked into the liquid pumping cylinder, which is convenient for the next addition. Therefore, the lubricating oil can be automatically added to the inside of the screw slide without manual addition, thereby avoiding the aggravation of the internal wear of the screw slide due to manual forgetting to add lubricating oil.

[0039] like Figure 3 and 7 As shown, in this embodiment, the closing mechanism 200 includes a round shell 201 fixedly connected to the slide rail 101, a winding wheel 202 is rotatably connected inside the round shell 201, a spring steel belt 203 fixedly connected to the side wall of the sliding seat 108 is sleeved on the outside of the winding wheel 202, the spring steel belt 203 is slidably embedded in the slide rail 101 and the top cover 102, a clockwork spring 204 is fixedly connected to the rotating shaft of the winding wheel 202, a disc 205 is sleeved on the outside of the clockwork spring 204, two support seats 103 are symmetrically fixedly connected to the bottom of the slide rail 101, and the top cover 102 is fixedly connected to the top of the slide rail 101.

[0040] In this embodiment, the sliding seat 108 and the slide rail 101 are arranged to slide in an embedded manner, and a top cover 102 is arranged on the top of the slide rail 101 to protect the ball screw 104, thereby preventing paint mist from falling on the ball screw 104 and the inside of the slide rail 101 and gradually solidifying to cause serious wear of the equipment, and the sliding seat 108 can pull one end of the spring steel belt 203 on the two side walls to move during the movement. Since the spring steel belt 203 is wound around the outside of the winding wheel 202, and a clockwork spring 204 is arranged on the central axis of the winding wheel 202, the spring steel belt 203 can be kept in a straight state when the sliding seat 108 moves, so as to close the gap between the slide rail 101 and the top cover 102, thereby playing the role of completely closing the inside of the screw slide, which can not only prevent dust and pollution and protect the internal mechanical structure from being invaded by dust, debris and other pollutants, but also ensure the high precision and high stability of the slide during the sliding process. The closed screw slide can reduce the frequency and cost of mechanical maintenance.

[0041] Embodiment 2

[0042] like Figure 8-10 As shown, in this embodiment, the lubrication mechanism 300 includes two cavity columns 301 fixedly arranged inside the sliding seat 108, and the cavity columns 301 are movably connected with a plurality of steel balls 302 at a medium distance, and a branch pipe 303 is fixedly connected between the two cavity columns 301, and the end of the branch pipe 303 is fixedly connected to one end of a hose 304, and the other end of the hose 304 is fixedly connected to an extrusion column 305, and a conical head 306 is fixedly connected to the side wall of the extrusion column 305, and the outside of the conical head 306 is fixedly sleeved with a piston cylinder 309, and the outside of the piston cylinder 309 is slidably sleeved with a pumping cylinder 310, and the end of the piston cylinder 309 is fixedly connected with an extrusion spring 311. The end of the pumping cylinder 310 is fixedly connected with a connecting column 312, and the center position of the connecting column 312 is fixedly connected with a suction pipe 314 connected thereto, and the outside of the suction pipe 314 is fixedly connected with an oil storage box 315, and the oil storage box 315 is fixedly connected to the side wall of the sliding seat 108. A valve ball 1 307 is arranged in the conical head 306 , and a return spring 308 is fixedly connected to the valve ball 1 307 . A plurality of infusion holes are equidistantly arranged in a ring shape at the end of the connecting column 312 , and a valve ball 2 313 is slidably engaged inside the connecting column 312 .

[0043] In specific implementation, when it is necessary to add lubricating oil to the surface of the ball and the screw, the cylinder 111 can first drive the movable plate 112 to approach the end of the slide rail 101, so that the movable plate 112 can drive the connecting rods 113 on both sides to swing, so that the ends of the connecting rods 113 can drive the rotating plate 114 to rotate until it is kept flush with the side plates of the slide rail 101. In this way, when the sliding seat 108 moves to the end of the slide rail 101, it will drive the extrusion column 305 and the rotating plate 114 to conflict with each other, so that the piston cylinder 309 can be pressed into the liquid pumping cylinder 310, and then the valve ball 307 can be squeezed out of the conical head 306 under the action of hydraulic pressure, and the lubricating oil will be squeezed from the liquid pumping cylinder 310 into the extrusion column 305 and the hose 304, and then it will be discharged into the branch pipe 303 and the two cavity columns 301. The lubricating oil in the cavity column 301 is in contact with each other, and then the lubricating oil on the surface of the steel ball 302 can lubricate the ball screw 104. When the extrusion column 305 and the rotating plate 114 no longer conflict with each other, the return spring 308 will squeeze the valve ball 1 307 to block the opening of the conical head 306, and then the extrusion spring 311 can squeeze the piston cylinder 309 to return to its original position, thereby driving the valve ball 2 313 to move inside the connecting column 312 under the action of negative air pressure, so that the suction tube 314 is connected to the inside of the liquid pumping cylinder 310 through the opening at the end of the connecting column 312, so that the lubricating oil in the oil storage box 315 can be sucked into the liquid pumping cylinder 310, which is convenient for the next addition. Therefore, the lubricating oil can be automatically added to the inside of the screw slide without manual addition, thereby avoiding the aggravation of the internal wear of the screw slide due to manual forgetting to add the lubricating oil.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
