[0027] The following is a more detailed description of the linkage type sandblasting angle adjustment device based on the sandblasting machine of the utility model in conjunction with the accompanying drawings and through specific implementation methods.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., 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 a limitation on the present invention.

[0029] The present embodiment discloses a linkage-type sandblasting angle adjustment device based on a sandblasting machine, which can drive the shot blaster of the shot blasting machine to adjust the overall angle through the linkage structure, avoid increasing resistance during shot blasting, achieve surface treatment of metal parts, and avoid affecting the speed and force of steel shots when thrown due to changes in the angle of the shot blasting port, thereby ensuring the cleaning efficiency of metal parts. At the same time, the linkage structure can also enable the shot blaster to swing uninterruptedly, thereby ensuring all-round treatment of the surface of metal parts, avoiding excessive cleaning of the surrounding area caused by cleaning a certain place, and preventing damage to metal parts. The device has a stable structure, simple installation, strong practicality, can effectively improve the surface cleaning effect, and is conducive to large-scale promotion. See. Figure 1 , Figure 2 , which mainly includes a sandblasting chamber 1, and a conveying barrel 101 is arranged at the bottom of the sandblasting chamber 1. A frame 102 is arranged at the bottom of the sandblasting chamber 1 on both sides of the conveying barrel 101. Sandblasting parts are distributed on the side walls of the sandblasting chamber 1. The sandblasting part 2 is hingedly arranged on the side wall of the sandblasting chamber 1. A linkage part 3 is arranged outside the side wall of the sandblasting chamber 1. Linkage shafts 201 are symmetrically arranged on the upper and lower sides of the sandblasting part 2. The linkage part 3 drives the linkage shaft 201 connected to the sandblasting part 2.

[0030] Through the above structure, when the sandblasting part 2 is performing the shot blasting operation, the linkage part 3 can drive the linkage part 2 to perform cyclic swinging, thereby performing multi-angle shot blasting and enhancing the surface treatment effect, as described in detail below.

[0031] To realize the hinged installation of the sandblasting part relative to the sandblasting room, see Figure 1 , Figure 2 , a mounting opening having a shape and specifications matching that of the hinged end of the base of the sandblasting unit 2 is provided on the side wall of the sandblasting chamber 1. The sandblasting unit 2 is hingedly provided at the mounting opening. By providing a mounting opening on the side wall of the sandblasting chamber 1, the sandblasting unit 2 can be installed on the side wall of the sandblasting chamber 1. In this embodiment, a plurality of mounting openings are provided on the side wall of the sandblasting chamber 1, and a sandblasting unit 2 is installed in each of the mounting openings. In order to ensure the surface treatment effect of the metal parts, the sandblasting unit 2 is arranged in a surrounding shape.

[0032] For details, see Figure 1 , Figure 2, Figure 3 , the base side of the sandblasting unit 2 is also provided with an articulated splint 202 and a clamping sleeve 203. The articulated splint 202 is symmetrically arranged on the base side of the sandblasting unit 2. The clamping sleeve 203 is connected to the hinge shaft on the side of the articulated splint 202 through a bearing 204. Through the connection of the bearing 204, the clamping sleeve 203 sets the sandblasting unit 2 at the installation port and the angle of the sandblasting unit 2 can be adjusted. The clamping sleeve 203 is fixedly arranged at the installation port of the side wall of the sandblasting chamber 1 by a retaining bolt. The sandblasting unit 2 is set at the installation port of the side wall of the sandblasting chamber 1 through the clamping sleeve 203. By setting the clamping sleeve 203, it is convenient to set the sandblasting unit 1 at the installation port of the side wall of the sandblasting chamber 1.

[0033] To achieve the cyclic oscillation of the sandblasting section, see Figure 1 , Figure 2 , the linkage part 3 includes a driving motor 301, a crankshaft 302 and a linkage rod 303. The driving motor 301 drives the crankshaft 302. In this embodiment, the driving motor 301 is a double-shaft reduction motor. The crankshafts 302 are arranged at the rotating shafts at both ends of the driving motor 301. The driving motor 301 can drive the crankshaft 302 to move through the rotating shafts at both ends. One end of the linkage rod 303 is hingedly connected to the crankshaft 302. The other end is hingedly connected to the linkage shaft 201 symmetrically arranged on the upper and lower sides of the sandblasting part 2. The crankshaft 302 is driven to rotate by the driving motor 301, and the rotation of the crankshaft 302 drives the linkage shaft 201 to move through its own structure, and the movement of the linkage shaft 201 drives the sandblasting part 2 to swing in a cycle.

[0034] Specifically, in order to realize that one driving motor drives multiple sandblasting parts to swing in a cycle, see Figure 1 The crankshaft 302 is arranged on the outer wall of the sandblasting chamber 1 at the side of the sandblasting part 2 through a shaft sleeve 321, and multiple crankshafts 302 are arranged on both sides of the sandblasting chamber 1. By arranging multiple crankshafts 302, multiple sandblasting parts 2 can be driven simultaneously.

[0035] In addition, the crankshafts 302 and 302 can be connected by a variety of transmission methods, such as bevel gear set connection, gear connection, universal coupling connection, etc. In this embodiment, the crankshafts 302 and 302 are preferably connected by a universal coupling 322 for transmission.

[0036] At the same time, in order to ensure that the crankshaft drives the sandblasting part smoothly and makes it swing, see Figure 2, the position of the connecting rod journal 323 of the crankshaft 302 corresponds to the position of the linkage shaft 201 of the sandblasting part 2. One end of the linkage rod 303 is hingedly connected to the connecting rod journal 323 of the crankshaft 302, and the other end is hingedly connected to the linkage shaft 201 of the sandblasting part 2. In actual implementation, the connecting position of the connecting rod journal 323 of the crankshaft 302 and the linkage rod 303, and the connecting position of the linkage rod 303 and the linkage shaft 201 can be connected by bearings to reduce friction and increase movement flexibility. At the same time, in order to ensure the smooth transmission of the crankshaft 302, a balancing weight can be set on the crankshaft 302 to offset the movement inertia of the connecting rod journal 323.

[0037] The working principle of the linkage sandblasting angle adjustment device based on the sandblasting machine of the utility model is as follows:

[0038] When installing the device, an installation port is opened on the existing sandblasting room for installation. After installation, the crankshaft can be driven to rotate by the driving motor, and the rotation of the crankshaft can drive the linkage rod to swing. The swing of the linkage rod drives the sandblasting part to swing in a cycle through the linkage shaft, so that the sandblasting part can perform shot blasting and swing at multiple angles at the same time.

[0039] It should be noted that, in the specific implementation of the device, the crankshafts can be connected to each other through a variety of transmission methods, such as bevel gear set connection, gear connection, etc., which will not be described in detail here. In addition, the structure described in the drawings of this specification is not a fixed and unchanging implementation method. For example, the number of crankshafts and sandblasting parts can be added or reduced according to actual needs. The drawings of this specification and the drawings of the abstract are only schematic diagrams and do not represent the actual position or actual number of sandblasting parts and crankshafts in specific implementation.
