[0002] The sandblasting machine belongs to the category of air conveying machinery. It uses compressed air in a pipeline to transport powdery granular materials from one place to another. During the process of converting kinetic energy into potential energy, the high-speed moving sand grains scour the surface of the object, so that the surface of the workpiece obtains a certain cleanliness and different roughness, improves the mechanical properties of the workpiece surface, enhances the anti-fatigue property of the workpiece, increases the adhesion between it and the coating, and prolongs the durability of the coating film.

[0003] For the rotary sandblasting machine, the turntable needs to be rotated frequently, so it is necessary to lubricate the bearing at the bottom of the turntable regularly. However, when lubricating the turntable bearing at present, it is necessary to stop the machine and then the staff carry out the lubrication operation. This method is rather cumbersome and will affect the efficiency of the sandblasting work at the same time.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

However, when lubricating the turntable bearing at present, it is necessary to stop the machine and then the staff carry out the lubrication operation. This method is rather cumbersome and will affect the efficiency of the sandblasting work at the same time, the basic concept of the technical solution adopted by the present utility model is:

[0006] A lubricating device for a rotary automatic sandblasting machine for a sensor inlet pressure head, comprising a sandblasting machine;

[0007] A turntable arranged at the bottom end of the inner wall of the sandblasting machine, a lubricating mechanism is arranged on the outer wall of the sandblasting machine, a protection mechanism is arranged at the bottom of the turntable, and the lubricating mechanism includes a fixed frame fixedly connected to the outer wall of the sandblasting machine:

[0008] A motor is fixedly connected to the inner wall of the fixed frame, and a rotating rod is fixedly connected to the output end of the motor. A fixed ring is fixedly connected to the outer wall of the top of the sandblaster, and an oil barrel is fixedly connected to the inner wall of the fixed ring. A first connecting pipe is communicated at the bottom of the oil barrel, and one end of the first connecting pipe away from the oil barrel is communicated with a piston cylinder. A second connecting pipe is communicated at the bottom end of the piston cylinder. A sliding rod movably penetrates through the outer wall of the piston cylinder. One end of the sliding rod is fixedly connected with a connecting plate. One end of the connecting plate close to the piston cylinder is fixedly connected with a spring, and the other end of the spring away from the connecting plate is fixedly connected to the outer wall of the piston cylinder. The other end of the sliding rod away from the connecting plate is fixedly connected with a piston plate. A groove is opened at the top end of the piston cylinder, and a sliding groove is opened on the inner wall of the groove. A sliding plate is slidably connected to the inner wall of the sliding groove, and a stress block is fixedly connected to the top end of the sliding plate.

[0009] As a preferred embodiment of the present invention, the protection mechanism includes a rotating groove opened at the bottom end of the turntable. A protection plate is movably arranged on the inner wall of the rotating groove. The bottom end of the protection plate is fixedly connected to the inner wall of the bottom end of the sandblaster. A ball is movably arranged at the top end of the protection plate, and the outer wall of the ball rolls on the inner wall of the rotating groove.

[0010] As a preferred embodiment of the present invention, the piston cylinder is arranged in a state where the left side is lower and the right side is higher below the oil barrel.

[0011] As a preferred embodiment of the present invention, the inner wall of the sliding groove is fitted with the outer wall of the sliding plate, and an inclined surface is arranged on the outer wall of the stress block.

[0012] As a preferred embodiment of the present invention, the piston plate is made of rubber material, and the outer wall of the piston plate is fitted with the inner wall of the piston cylinder.

[0013] As a preferred embodiment of the present invention, the number of the balls is several, and the balls are evenly distributed at equal intervals at the top end of the protection plate.

[0014] As a preferred embodiment of the present invention, the inner wall of the rotating groove is fitted with the outer wall of the protection plate.

[0015] The present invention has the following beneficial effects compared with the prior art:

[0016] In this utility model, when the starting motor is activated, the output end thereof will drive the rotating rod to rotate. Then, the rotating rod will contact and exert a squeezing force on the force-receiving block. The force-receiving block being squeezed will move to the right, thereby driving the sliding plate to move to the right along the inner wall of the sliding groove. Through the movement of the sliding plate, the piston plate can be driven to move along the inner wall of the piston cylinder. At the same time, during the movement of the piston plate, the sliding rod and the connecting plate will be driven to move. Then, through the movement of the connecting plate, the spring can be squeezed. In this way, the piston plate can push the lubricating oil inside the piston cylinder, causing the lubricating oil to flow from the lower side to the higher side of the piston cylinder. Subsequently, the lubricating oil will be transported through the second connecting pipe to the bearing at the bottom of the turntable for rotation, thereby completing the lubrication function. After the lubrication is completed, continue to rotate the motor so that the rotating rod no longer contacts the force-receiving block. Then, the spring rebounds and resets to drive the piston plate to reset. In this way, the lubricating oil will flow to the lower side of the piston cylinder due to the gravity of the piston cylinder with a lower left and a higher right, thus stopping the oil injection. During this process, there is no need for parking operation at all, and there is also no need for manual operation, which simplifies the lubrication process and improves the sandblasting efficiency.

[0017] In this utility model, during the rotation of the turntable, the balls at the top of the protective plate will rotate along the inner wall of the rotating groove. At the same time, the protective plate can play a certain protective role for the bearing at the bottom of the turntable, preventing the emery from adhering to it, thereby affecting the rotation effect of the turntable.

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0027] As Figures 1 to 5 shown, a lubricating device for a rotary automatic sandblasting machine for a sensor inlet pressing head includes a sandblasting machine 1, a turntable 2 arranged at the bottom end of the inner wall of the sandblasting machine 1, a lubricating mechanism 31 arranged on the outer wall of the sandblasting machine 1, and a protection mechanism 32 arranged at the bottom of the turntable 2. The lubricating mechanism 31 includes a fixed frame 311 fixedly connected to the outer wall of the sandblasting machine 1, a motor 312 fixedly connected to the inner wall of the fixed frame 311, a rotating rod 313 fixedly connected to the output end of the motor 312, a fixed ring 314 fixedly connected to the outer wall of the top of the sandblasting machine 1, an oil barrel 315 fixedly connected to the inner wall of the fixed ring 314, a first connecting pipe 316 communicated at the bottom of the oil barrel 315, a piston cylinder 317 communicated at one end of the first connecting pipe 316 away from the oil barrel 315, a second connecting pipe 318 communicated at the bottom end of the piston cylinder 317, a slide bar 319 movably penetrating through the outer wall of the piston cylinder 317, a connecting plate 3110 fixedly connected to one end of the slide bar 319, a spring 3111 fixedly connected to the outer wall of one end of the connecting plate 3110 close to the piston cylinder 317, the spring 3111 fixedly connected to the outer wall of the piston cylinder 317 at the end away from the connecting plate 3110, a piston plate 3112 fixedly connected to the end of the slide bar 319 away from the connecting plate 3110, a groove opened at the top end of the piston cylinder 317, a chute 3113 opened on the inner wall of the groove, a slide plate 3114 slidably connected to the inner wall of the chute 3113, and a force-bearing block 3115 fixedly connected to the top end of the slide plate 3114.

[0028] Furthermore, the piston cylinder 317 is arranged below the oil barrel 315 in a state of being lower on the left and higher on the right. In this way, when the motor 312 is not started, the lubricating oil inside the piston cylinder 317 will always be at the left lower end inside it.

[0029] Further, the inner wall of the sliding groove 3113 is fitted with the outer wall of the sliding plate 3114, and the outer wall of the force-receiving block 3115 is provided with an inclined surface, so as to ensure that the force-receiving block 3115 can be squeezed by the rotating rod 313, thereby driving the sliding plate 3114 and the piston plate 3112 to move.

[0030] Furthermore, the piston plate 3112 is made of rubber material, and the outer wall of the piston plate 3112 is fitted with the inner wall of the piston cylinder 317, so as to ensure the tight fit between the outer wall of the piston plate 3112 and the inner wall of the piston cylinder 317, thereby ensuring the sealing performance of the inner wall of the piston cylinder 317.

[0031] The protection mechanism 32 includes a rotating groove 321 opened at the bottom end of the turntable 2. The inner wall of the rotating groove 321 is movably provided with a protection plate 322. The bottom end of the protection plate 322 is fixedly connected to the bottom end of the inner wall of the sandblasting machine 1. The top end of the protection plate 322 is movably provided with a ball 323, and the outer wall of the ball 323 rolls on the inner wall of the rotating groove 321.

[0032] Further, the number of the balls 323 is several, and the balls 323 are evenly distributed at equal intervals on the top end of the protection plate 322, so as to reduce the friction between the top end of the protection plate 322 and the inner wall of the rotating groove 321, making the rotation of the turntable 2 more smooth.

[0033] Furthermore, the inner wall of the rotating groove 321 is fitted with the outer wall of the protection plate 322, so as to ensure the tight fit between the outer wall of the protection plate 322 and the inner wall of the rotating groove 321, thereby ensuring the stability of the turntable 2 during rotation.

[0034] The implementation principle of the lubrication device of a rotary automatic sandblasting machine for the sensor inlet pressure head in this embodiment is as follows: First, lubricating oil is injected into the oil barrel 315, and the oil barrel 315 stores the lubricating oil. When it is necessary to lubricate the bearing at the bottom of the turntable 2, the motor 312 can be started, and its output end will drive the rotating rod 313 to rotate. Then the rotating rod 313 will contact and extrude the force-receiving block 3115. The force-receiving block 3115 being extruded will move to the right, thereby driving the slide plate 3114 to move to the right along the inner wall of the chute 3113. The movement of the slide plate 3114 can drive the piston plate 3112 to move along the inner wall of the piston cylinder 317. At the same time, during the movement of the piston plate 3112, the slide rod 319 and the connecting plate 3110 will be driven to move. Then, through the movement of the connecting plate 3110, the spring 3111 will be extruded. In this way, the piston plate 3112 can push the lubricating oil inside the piston cylinder 317, causing the lubricating oil to flow from the lower side to the higher side of the piston cylinder 317. Subsequently, the lubricating oil will be transported through the second connecting pipe 318 to the bearing at the bottom of the turntable 2 for rotation, thus completing the lubrication. After the lubrication is completed, continue to rotate the motor 312 so that the rotating rod 313 no longer contacts the force-receiving block 3115. Then the spring 3111 rebounds and resets to drive the piston plate 3112 to reset. In this way, the lubricating oil will flow to the lower side of the piston cylinder 317 due to the gravity of the piston cylinder 317 being lower on the left and higher on the right, thereby stopping the oil injection. During this process, there is no need to stop the machine operation at all, and there is also no need for manual operation, simplifying the lubrication process and improving the sandblasting efficiency.

[0035] During the rotation of the turntable 2, the balls 323 at the top of the protective plate 322 will rotate along the inner wall of the rotating groove 321. At the same time, the protective plate 322 can play a certain protective role for the bearing at the bottom of the turntable 2, preventing the emery from adhering to it and thus affecting the rotation effect of the turntable 2.
