DETAILED DESCRIPTION

[0023] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 and Figure 2 The utility model provides a stress relief platform for cylinder castings, including a vibration platform 1, a rubber anti-vibration base 2 and a vibration motor 3 are installed at the bottom of the vibration platform 1, a plurality of concave longitudinal grooves 6 are opened on the top of the vibration platform 1, a shifting and driving mechanism 5 is arranged on the top of the concave longitudinal grooves 6, a multi-point pressure plate assembly 4 is fixedly installed at the output end of the shifting and driving mechanism 5, and the shifting and driving mechanism 5 is used to control the lifting and lowering of the multi-point pressure plate assembly 4;

[0025] The multi-point pressure plate assembly 4 includes a main pressure plate 41, and a plurality of through openings are opened on the top of the main pressure plate 41. Telescopic pressure rods 42 are fixedly connected in the plurality of through openings. The plurality of telescopic pressure rods 42 are evenly divided into a plurality of groups, and each group of telescopic pressure rods 42 is vertically aligned with a plurality of concave longitudinal grooves 6.

[0026] Reference Figure 2 The telescopic pressure rod 42 includes a fixed cylinder 421, and the inner cavity of the fixed cylinder 421 is slidably sleeved with a column 422. The bottom end of the column 422 is fixedly connected to a pressure plate 423, and the top of the fixed cylinder 421 is fixedly connected to a cover cylinder 424. The top of the column 422 is transmission-connected to the top of the inner wall of the cover cylinder 424 through a spring 425. When the multi-point pressure plate assembly 4 moves downward to press the casting inside the concave longitudinal groove 6 through the telescopic pressure rod 42, the pressure plate 423 contacts the casting at this time. When the casting pressed by a certain telescopic pressure rod 42 is large in size, the pressure plate 423 contacts the casting to generate a reaction force to make the column 422 shrink toward the inside of the cover cylinder 424, thereby adapting to the height of castings of different sizes. The elastic force of the spring 425 can ensure that the telescopic pressure rod 42 maintains a certain pressure on the casting to fix it, thereby enabling a number of telescopic pressure rods 42 to achieve a pressing and fixing effect on castings of different sizes.

[0027] Reference Figure 2 , 3 An inner column 426 is fixedly connected to the top of the inner wall of the cover cylinder 424, and the column 422 is slidably sleeved on the side wall of the inner column 426. The inner column 426 passes through the inner cavity of the spring 425. By setting the inner column 426, the spring 425 can be prevented from bending during the compression process, thereby improving the service life of the spring 425.

[0028] Reference Figure 3 The top of the side wall of the column 422 is fixedly connected with an anti-slip ring 427, and the diameter of the anti-slip ring 427 is larger than the inner diameter of the fixed tube 421. By setting the anti-slip ring 427, the column 422 can be prevented from falling off from the inner cavity of the fixed tube 421 due to the elastic force of the spring 425.

[0029] Reference Figure 4 The driving mechanism 5 includes a gantry frame 51, and an electric cylinder 52 is fixedly installed on the top of the gantry frame 51. The output end of the electric cylinder 52 passes through the gantry frame 51 and is fixedly connected to the top of the main pressure plate 41 through a seismic isolation connector 53. When in use, the main pressure plate 41 can be driven to rise and fall through the output and retraction of the electric cylinder 52, thereby replacing manpower. During the operation of the device, the seismic isolation connector 53 can be used for shock absorption to avoid the vibration force from affecting the electric cylinder 52.

[0030] Reference Figure 4A positioning shaft 55 is provided at the top of the inner wall of the gantry frame 51, and an ear block 54 is slidably sleeved on the side wall of the positioning shaft 55. The ear block 54 is fixedly connected to the side wall of the main body pressure plate 41. By arranging the ear block 54 and the positioning shaft 55, the stability of the main body pressure plate 41 during lifting and lowering can be improved.

[0031] Reference Figure 5 The seismic isolation connector 53 includes a fixed plate 531, a rubber seismic isolation plate 532, and a plurality of L-shaped hanging plates 533. The rubber seismic isolation plate 532 is fixedly connected to the bottom of the fixed plate 531. The top of the fixed plate 531 is fixedly connected to the output end of the electric cylinder 52. The bottom of the rubber seismic isolation plate 532 is fixedly connected to the top of the main body pressure plate 41. The plurality of L-shaped hanging plates 533 are distributed in an annular shape and are fixedly connected to the top of the main body pressure plate 41. The transverse plates of the plurality of L-shaped hanging plates 533 all extend to the top of the fixed plate 531. When the electric cylinder 5 2 output, the multi-point pressure plate assembly 4 is compressed by the fixed plate 531 and the rubber isolation plate 532, and the multi-point pressure plate assembly 4 can be isolated by the flexibility of the rubber isolation plate 532 to prevent the vibration force from being transmitted to the electric cylinder 52. When the electric cylinder 52 contracts and drives the fixed plate 531 to rise, a plurality of L-shaped hanging plates 533 are suspended on the top of the fixed plate 531, and the multi-point pressure plate assembly 4 is lifted up by the plurality of L-shaped hanging plates 533, thereby preventing the rubber isolation plate 532 from being broken due to its poor rigidity.

[0032] Reference Figure 4 The inner cavity of the ear block 54 is provided with an O-shaped rubber ring, and the positioning shaft 55 passes through the inner cavity of the O-shaped rubber ring. The O-shaped rubber ring can achieve a shock-absorbing effect to prevent the vibration force from being transmitted to the gantry frame 51 through the positioning shaft 55.

[0033] The working principle of the utility model is as follows: when in use, the smaller cylinder casting can be placed on the top of the vibration platform 1, and the larger cylinder casting can be placed inside the concave longitudinal groove 6. At this time, after the multi-point pressure plate assembly 4 is pressed down by the driving mechanism 5, the main pressure plate 41 can press and fix the casting on the top of the vibration platform 1. At this time, each group of telescopic pressure rods 42 respectively penetrates into a number of concave longitudinal grooves 6, and a number of castings inside the concave longitudinal grooves 6 are respectively pressed by a number of telescopic pressure rods 42. Since the telescopic pressure rods 42 have telescopic characteristics, when the castings stored inside the concave longitudinal grooves 6 have size differences, the telescopic pressure rods 42 are used to telescope and retract, so as to match the heights of castings of different sizes. This can cope with the size differences of castings in different parts of the cylinder, and avoid the situation where some castings fall off due to their small size and weak fixation.
