[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, in some embodiments, the shot blasting device for the hydraulic component housing includes a fixed base 3, a transmission assembly 4 and a bearing assembly 5. The transmission assembly 4 is connected to the fixed base 3 to form a stable transmission mechanism, and the bearing assembly 5 is in transmission connection with the transmission assembly 4. Through this design, the transmission assembly 4 can stably drive the bearing assembly 5 to move forward and backward, so that the bearing assembly 5 can bring the hydraulic component housing 6 into the shot blasting bin, and the shot blasting machine 1 performs shot blasting on it, thereby improving work efficiency and quality.

[0020] In particular, a rotating mechanism and a sliding mechanism 53 are provided in the bearing assembly 5, and the sliding mechanism 53 is slidably connected to the fixed base 3, so that the bearing assembly 5 can slide freely on the fixed base 3. The rotating mechanism is arranged in the sliding mechanism 53, so that the rotating mechanism can move accurately under the guidance of the sliding mechanism 53.

[0021] The rotating mechanism is provided with a carrier frame 52 and a first motor 54, the output end of the first motor 54 is fixedly connected to the carrier frame 52, the first motor 54 drives the carrier frame 52 to rotate, and the hydraulic component housing 6 to be shot blasted is installed on the carrier frame 52. Driven by the first motor 54, the carrier frame 52 can rotate, so that the hydraulic component housing 6 can be evenly impacted by the steel shot during the shot blasting process, thereby achieving an ideal shot blasting effect.

[0022] In addition, the sliding mechanism 53 is provided with a limiting groove 532, and the carrier 52 is provided with a limiting block 521, and the limiting block 521 is arranged corresponding to the limiting groove 532. This design can effectively limit the rotation range of the carrier 52, thereby improving the safety and reliability of the equipment.

[0023] It should be particularly noted that, in the present embodiment, two working stations are provided, one of which is set as a loading and unloading station, and the other is set as a shot blasting bin. The hydraulic component housing 6 is installed on the carrier frame 52 at the loading and unloading station, and the transmission assembly 4 drives the carrier assembly 5 to move into the shot blasting bin. When the sliding mechanism 53 drives the rotating mechanism to move to the shot blasting bin, the first motor 54 is started, and the first motor 54 drives the carrier frame 52 to rotate, thereby causing the hydraulic component housing 6 to rotate with the carrier frame 52, so that the shot blasting machine 1 can perform shot blasting on different positions of the hydraulic component housing 6, so that it can achieve an ideal shot blasting effect.

[0024] When the hydraulic housing 6 is shot blasted, the transmission assembly 4 drives the bearing assembly 5 to move to the upper and lower material loading station, and the operator checks the effect of the shot blasting, removes the hydraulic housing 6 from the bearing frame 52, and reinstalls the hydraulic housing 6 to be shot blasted. During this period, the used steel shots are collected and processed by an external steel shot collection device for reuse.

[0025] It is worth noting that due to the high speed of the steel shots thrown by the shot blasting machine 1, in the current process, when the hydraulic component housing 6 is shot blasted using a hook-type shot blasting device, the position of the hydraulic component housing 6 will continue to change, which inevitably causes local excessive shot blasting or incomplete local shot blasting.

[0026] In this embodiment, the hydraulic component housing 6 is installed on the carrier frame 52 to ensure the stability of the position of the hydraulic component housing 6 during the shot blasting process, and the carrier frame 52 is driven to rotate through the rotating mechanism, so that the hydraulic component housing 6 can be evenly impacted by the steel shots during the shot blasting process, thereby achieving an ideal shot blasting effect.

[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments, the fixed base 3 includes a support platform 31, a support side plate 34 and a support end plate 35. Specifically, the support side plate 34 is arranged at the lower position of the support platform 31 to provide a stable support. The two ends of the support platform 31 are respectively equipped with support end plates 35, which enhance the stability of the support platform 31. In addition, inclined plates 33 are respectively installed on both sides of the support platform 31, and the design of these inclined plates 33 is intended to optimize the flow and collection of steel shots during the shot blasting process.

[0028] In the support platform 31, a slide rail 32 is specially provided, and the slide rail 32 provides a sliding path for the sliding mechanism 53. The sliding mechanism 53 can move smoothly along the slide rail 32, thereby realizing accurate control and operation of the bearing assembly 5. In order to ensure efficient and stable power transmission of the transmission assembly 4, a first through hole 36 is specially designed on the support end plate 35. This first through hole 36 is directly connected to the transmission assembly 4.

[0029] Further, in some embodiments, the transmission assembly 4 includes a second motor 41 and a transmission screw 42, wherein the second motor 41 is transmission-connected to one end of the transmission screw 42, thereby ensuring effective transmission of power. Both ends of the transmission screw 42 are axially connected to the two first through holes 36, respectively, and such a design enables the transmission screw 42 to be stably mounted on the support end plate 35, thereby ensuring stable operation of the transmission assembly 4. In addition, the second motor 41 is fixedly connected to one of the support end plates 35, and such a structural design enhances the stability of the transmission assembly 4.

[0030] like Figure 3 , Figure 5 and Figure 7As shown, in some embodiments, the sliding mechanism 53 further includes a fixed plate 531, a fixed frame 533 and a slider 534. Specifically, the fixed plate 531 is arranged on the upper part of the fixed frame 533, and the two are fixed as a whole through a connecting plate, and a slide groove is arranged between the two, and the slide groove is arranged corresponding to the slide rail 32. Through the mutual cooperation between the slide groove and the slide rail 32, the sliding mechanism 53 can move along the slide rail 32. In particular, a second through hole 535 is arranged on the fixed plate 531, and the second through hole 535 passes through the fixed frame 533. In addition, the first motor 54 is arranged inside the fixed frame 533, and its output end extends through the second through hole 535 to be fixedly connected to the carrier frame 52, and the first motor 54 can drive the carrier frame 52 to rotate.

[0031] In order to ensure the accurate movement of the carrier 52, a limiting groove 532 is provided on the fixing plate 531. The limiting groove 532 is coaxially arranged with the second through hole 535, and such a design can effectively limit the movement range of the limiting block 521, ensuring that it moves within a predetermined track.

[0032] The slider 534 is placed at the bottom of the fixed frame 533, and the two are welded and fixed therebetween, and the slider 534 is connected to the transmission screw 42 by means of threaded transmission. This connection method enables the slider 534 to respond to the rotational movement of the transmission screw 42, thereby achieving precise linear movement. In this way, the sliding mechanism 53 can efficiently control the position of the hydraulic component housing 6 during the shot blasting process, ensuring the uniformity and efficiency of the shot blasting.

[0033] Furthermore, in some embodiments, the rotating mechanism further includes a fixed shaft 51, which is disposed on the carrier 52, and is intended to be connected to a connecting hole on the hydraulic housing 6. With such a design, it is possible to ensure that the hydraulic housing 6 can rotate stably during the shot blasting process, thereby improving the efficiency and quality of the shot blasting.

[0034] Furthermore, in some embodiments, the carrier 52 is provided with a plurality of working surfaces, each of which is provided with a certain inclination angle, and the fixed shaft 51 is provided corresponding to the working surfaces. Specifically, the fixed shaft 51 is placed on each working surface, so that the hydraulic component housing can be in an inclined state during the shot blasting operation. Such a design enables the carrier 52 to be equipped with a plurality of hydraulic component housings 6, so that a plurality of hydraulic component housings 6 can be processed in a single shot blasting operation.

[0035] like Figure 1 and Figure 2As shown, in some embodiments, the shot blasting device for the hydraulic component housing also includes a shot blasting machine 1 and a shell 2. The shell 2 is arranged at one end of the fixed base 3. The fixed base 3 is divided into two operating workstations by the shell 2. The workstation outside the shell 2 is a loading and unloading workstation, and the workstation inside the shell 2 is a shot blasting bin. The shell 2 is fixedly connected to the bottom of the inclined plate 33.

[0036] In particular, the housing 2 is provided with a cabinet door, which is used to close the housing 2 to ensure that the shell 6 will not be disturbed by the external environment during the shot blasting process.

[0037] The shot blasting machine 1 is arranged on the top of the housing 2, and the opening of the shot blasting machine 1 is directed toward the hydraulic component housing 6. In this way, the shot blasting machine 1 can efficiently perform surface treatment on the hydraulic component housing 6, remove impurities and rust on the surface, and thus achieve the purpose of cleaning and strengthening the housing surface.

[0038] like Figure 8 As shown, in some embodiments, a flexible sealing plate is provided on the side wall of the slide rail 32, and the function of the flexible sealing plate is to effectively block and prevent the steel shots from falling into the interior of the slide rail 32, thereby ensuring the smooth progress of the shot blasting process and the convenience of cleaning and maintenance of the shot blasting device.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, two shot blasting machines 1 are provided, and the two shot blasting machines 1 are designed to be symmetrically arranged along the longitudinal center line of the fixed base 3. This symmetrical arrangement ensures the uniformity and efficiency of the shot blasting process, so that the hydraulic component housing 6 can be fully and evenly cleaned and strengthened during the shot blasting process.

[0040] The typical working process of the above embodiment is as follows: First, at the loading and unloading station, multiple hydraulic component housings 6 to be processed are installed on the carrier frame 52, and the second motor 41 is started. The bearing assembly 5 is moved into the shot blasting bin through the joint action of the transmission screw 42 and the slider 534, and the cabinet door of the outer shell 2 is closed to put the shot blasting bin in a closed state.

[0041] Secondly, start the shot blasting machine 1 located on the top of the shell 2, and drive the first motor 54 at the same time, so that the first motor 54 drives the carrier 52 to rotate, and then the hydraulic component housing 6 rotates with the carrier 52, so that the shot blasting machine 1 can shot blast different positions of the hydraulic component housing 6.

[0042] Finally, when the hydraulic housing 6 has completed the shot blasting, the second motor 41 drives the transmission screw 42 to move the bearing assembly 5 to the loading and unloading station, and the operator checks the effect of the shot blasting, removes the hydraulic housing 6 from the bearing frame 52, and reinstalls the hydraulic housing 6 to be shot blasted. During this period, the used steel shots are collected and processed by an external steel shot collection device for reuse.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
