Referring to fig. 1-7, the present invention provides a technical solution: a surface treatment device for processing a sensor shell comprises a circular truncated cone ring barrel 10 with a vertical large axis and a vertical small axis, a horizontal bottom plate 11 is fixedly arranged on the bottom surface of the circular truncated cone ring barrel 10, a chamfer 12 is arranged between the bottom plate 11 and the circular truncated cone ring barrel 10, a plurality of through holes 13 are vertically arranged on the bottom plate 11, a power shaft 14 is coaxially and rotatably arranged in the center of the bottom plate 11, a screw mechanism for driving the sensor shell to move upwards is fixedly arranged on the outer wall of the power shaft 14, the screw mechanism comprises an inverted cone-shaped screw plate 15, the height of two ends of any vertical section of the screw plate 15 is high, the middle of the vertical section of the screw plate 15 is low, a plurality of through holes 16 are vertically arranged on the screw plate 15, the through holes 16 in any vertical direction are not overlapped, the lower end of the circular truncated cone ring barrel 10 is provided with a circulating device for recovering gravel, and the side wall of the lower end of the circular truncated cone ring barrel 10 is provided with a feeding device which is triggered by the spiral plate 15 to advance and accurately feed;
before the device is used, the device is assembled, the sensor shell made of metal materials and needing surface treatment is transferred to a treatment site, the surface of the sensor metal shell is observed one by one, if products with large cracks and large surface curvature fluctuation are removed, waste of processing resources is avoided, as shown in fig. 1, the front end of the device is seen from the left side to the right side of fig. 1, the upper end of the device is seen from the upper side to the lower side of fig. 1, the right end of the device is seen from the upper side of fig. 1, and the device is described by adopting the direction of equipment, so that the device is not described again; when the device is placed, the axis of the circular truncated cone-shaped circular barrel 10 of the equipment needs to be ensured to be vertical to the horizontal plane (the power shaft 14 is driven to rotate at a low speed by external power);
when the invention is used, a sensor metal shell is placed in the circular truncated cone ring barrel 10 from a feeding device on the side wall of the lower end of the circular truncated cone ring barrel 10, external power drives the power shaft 14 to rotate, the power shaft 14 rotates to drive the spiral plate 15 to rotate (as shown in figure 2, a large interval is arranged between the lower end of the spiral plate 15 and the bottom plate 11, so that the sensor metal shell can not be directly contacted with the spiral plate 15 when sinking at the bottom of the bottom plate 11, thereby causing the problem of equipment jamming), the spiral plate 15 rotates to transmit the sensor metal shell upwards, meanwhile, gravel passes through the through hole 16 on the spiral plate 15 under the action of self gravity, and descends (the through hole 16 does not vertically coincide, thereby preventing the gravel from directly falling to the lowest end of the circular truncated cone ring barrel 10), the spiral plate 15 drives the sensor metal shell to ascend and revolve in the rotating process and is positioned at the lowest point in the middle of the spiral plate 15 (as shown in figure 2), meanwhile, the metal shell of the sensor can move outwards along the axial line of the power shaft 14 in the radial direction under the action of centrifugal force, the metal shell of the sensor moves to the high position outside the spiral plate 15 and then rolls to the lowest position of the spiral plate 15, so that dead corners in deburring are avoided, and compared with the conventional circular truncated cone ring barrel 10 with the same diameter from top to bottom, the circular truncated cone ring barrel 10 with the small lower end and the large upper end is adopted, so that sand gravel can be poured into the circular truncated cone ring barrel 10 more easily, and further, the sand gravel with the small lower end and the same mass can be quickly gathered to the lower end of the small circular truncated cone ring barrel 10 (the upper end is easy to unload) in the invention, so that the clearance of the sand gravel is reduced, the friction force is increased, and the pressure is applied to the metal shell of the sensor at the lower end at the same time, so that the larger friction force is provided, the resistance of the metal shell of the sensor is increased along with the rising of the spiral plate 15, so that efficient deburring can be realized, and the metal shell of the sensor at the lower end is positioned at a closer distance from the power shaft 14 and is smaller centrifugal force, therefore, the problem that a sensor metal shell is thrown to the boundary of the circular truncated cone-shaped annular barrel 10 to cause a deburring dead angle is avoided, secondly, the sand has certain fluidity, and when the spiral plate 15 rotates, the sensor metal shell on the upper end face of the bottom plate 11 can flexibly move onto the spiral plate 15, so that the problem of blocking is avoided;
when the sand continuously descends and passes through the through holes 13 on the bottom plate 11 (the chamfer 12 is used for avoiding the problem of static dead angles of the sand, and the mobility is poor), the sand flows up and down, and moves in the reverse direction with the metal shell of the sensor, so that the deburring efficiency is accelerated;
when the metal shell of the sensor is transmitted to the upper end of the circular truncated cone-shaped ring barrel 10 by the spiral plate 15, the metal shell of the sensor is usually positioned at the outer edge of the spiral plate 15 due to the increase of centrifugal force, and then blanking is carried out;
according to the invention, through the circular table ring barrel 10 with the large upper part and the small lower part, sand is rapidly accumulated, the interval is reduced, the friction force is increased, the deburring effect of the sensor metal shell is better, the sand adding speed is low, the unloading is convenient, the sensor metal shell is driven by the spiral plate 15 to ascend while revolving, the larger friction with the sand is increased, the deburring is carried out, then the sensor metal shell is driven by the rotation of the spiral plate 15 to revolve, the centrifugal force moves outwards, and the sensor metal shell is combined with the shapes of the spiral plate 15 with the two edges high and the middle low, so that the sensor metal shell rolls, the angle is changed, and the surface treatment process for efficiently deburring without dead angles can be carried out on the sensor metal shell.
